Dr. Reed's SIX WOUND HEALING FACTORS

1. Diabetic Glucose Control

Stable blood sugar levels are critical for wound healing. High glucose causes arteriole narrowing , restricting oxygen and antibiotic delivery to tissues. This leads to poor circulation, weakened immune response, and stalled healing . Proper glucose control prevents these complications and promotes faster recovery .

2. Wound Microcirculation & Vascular Health

Healthy blood flow is essential for healing. Many diabetic patients suffer from Peripheral Arterial Disease (PAD) , restricting circulation. Dr. Reed uses advanced capillary refill testing and nitroglycerin patches to enhance microcirculation and reverse diabetic complications such as neuropathy.

3. Wound Tissue Growth Stimulation

Regular debridement (removal of dead tissue) and proper wound care stimulate new cell growth. Weekly treatments by Dr. Reed ensure:

✔ Removal of non-viable tissue

✔ Elimination of bacterial biofilm

✔ Stimulation of platelet-derived growth factors to support healing

4. Infection Control & Antibiotic Management

Targeted antibiotic therapy is key to fighting infection. Dr. Reed:

✔ Uses tissue and bone cultures (not surface swabs) for accurate diagnosis

✔ Prescribes customized antibiotic treatments to combat resistant bacterial strains

✔ Ensures proper white blood cell migration to fight infection effectively

5. Pressure Off-Loading & Wound Protection

Pressure relief is vital for wound healing. Continuous pressure restricts blood flow, oxygen delivery, and immune response . Dr. Reed provides customized solutions such as:

✔ Diabetic shoes, braces, and insoles

✔ Knee scooters or wheelchairs for non-weight bearing

✔ Surgical corrections for foot stability when necessary

6. Nutrition & Metabolic Supplementation

Diabetic patients often suffer from nutritional deficiencies , which hinder healing. Key concerns include:

✔ Low albumin levels (affecting circulation, enzyme function, and tissue repair)

✔ Vitamin B1 (Thiamin) & B12 (Cobalamin) deficiencies , leading to nerve damage and poor oxygenation

✔ Personalized dietary plans to stabilize glucose and optimize healing

✔ Intermittent Fasting to Improve Diabetic Control

Innovative Approaches for Diabetic Wound Healing

Dr. Reed has successfully guided diabetic patients through an intermittent fasting protocol (16/8 method) , which has significantly reduced insulin dependency and improved HbA1C levels. Patients receive detailed instructions on dietary strategies and supplement recommendations to support their metabolic health.

These advanced therapies are combined with Dr. Reed’s Six-Point Wound Healing Protocol , which includes daily wound care, weekly debridement, and comprehensive healing strategies to ensure optimal recovery.

A TEAM APPROACH TO WOUND HEALING

The key to turning around a non-healing diabetic wound is a comprehensive examination to uncover underlying medical conditions that may be preventing proper healing. Many patients with chronic wounds also suffer from systemic issues such as:

✅ Peripheral Vascular Disease – Poor circulation affecting wound oxygenation
✅ Immune Compromise – Reduced ability to fight infections
✅ Anemia & Nutritional Deficiencies – Lack of essential nutrients for tissue repair
✅ Diabetes Instability – Uncontrolled glucose levels delaying healing
✅ Incorrectly Identified Infections – Inaccurate antibiotic use prolonging recovery
✅ Failure to Off-Load Pressure – Continued pressure causing recurrent ulceration

With over 30 years of experience , Dr. Mark Reed works alongside a team of specialists to address these challenges, collaborating with Vascular Surgeons, Vein Specialists, Interventional Radiologists, Infectious Disease Experts, Endocrinologists, and Diabetologists to resolve underlying factors and accelerate wound healing.

MODERN ADVANCES TO PREVENT DIABETIC COMPLICATIONS

Modern medicine has made significant advancements in diabetes management, allowing for better monitoring, control, and even remission with the right combination of medication, nutrition, and specialized diabetic footwear. These improvements help prevent microvascular ischemia and other diabetic complications, reducing the risk of chronic wounds.

Cutting-Edge Treatments for Diabetic Ulcers

Today’s advanced wound care options provide faster and more effective healing than ever before. These include:
✅ Nitroglycerin Therapy – Reverses microvascular ischemia to restore blood flow
✅ Ultramist® Ultrasound Therapy – Stimulates tissue growth and accelerates healing
✅ Skin Substitute Grafts – Provides essential coverage for ulcer healing
✅ Negative Pressure Therapy – Enhances granulation and tissue regeneration

Surgical Solutions for Chronic Wounds

For some patients, surgery is the key to lasting wound healing. Two proven surgical procedures include:

�� Floating Metatarsal Head Osteotomies – A minimally invasive surgery performed under local anesthesia that rebalances foot pressure, allowing chronic ulcers to heal while the patient remains weight-bearing.

�� Percutaneous Achilles Lengthening – For patients with transmetatarsal amputations, this procedure helps rebalance forefoot pressure, significantly improving wound healing and preventing future complications.

With the right approach, diabetic wounds can heal, and complications can be prevented.

Intermittent Fasting to Control Diabetes

For over 30 years , Dr. Mark Reed has helped heal and prevent diabetic ulcers and many different types of wounds while improving insulin management through an intermittent fasting 16/8 protocol . Patients with Type 1 and Type 2 diabetes have experienced:

✔ Reduced daily insulin requirements (from 120+ units to below 30 )

✔ Lower HbA1C levels (from 11-12 to below 7 )

Nutritional Support for Diabetic Patients

Proper nutritional supplementation should be managed by a healthcare provider to avoid medication interactions. Recommended brands include Costco Kirkland and Centrum , with dosages kept within the recommended daily allowance (RDA) —avoiding megadose vitamins that may strain the liver. Glucose monitoring and insulin adjustments are essential, and patients receive detailed guidance on fasting and nutritional supplements while working closely with their Internist or Diabetologist .

Research shows that intermittent fasting can be a safe and effective strategy for managing Type 1 and Type 2 diabetes , leading to weight loss, reduced insulin needs, and improved metabolic function . Studies indicate that, with proper medication adjustments and blood glucose monitoring , intermittent fasting can:

✔ Enhance insulin sensitivity and reduce insulin resistance

✔ Lower blood pressure and oxidative stress

✔ Increase hemoglobin levels and oxygen-carrying capacity

✔ Improve overall metabolic function

With medical supervision , intermittent fasting can be a powerful tool for diabetes control and overall health improvement . Always consult a healthcare provider before making dietary changes.Intermittent fasting for patients

Intermittent Fasting & Diabetes: Research-Backed Benefits

Studies show that intermittent fasting can significantly improve insulin sensitivity, blood pressure, and oxidative stress —even without weight loss ( Sutton et al., 2018 ). With proper medication adjustments and glucose monitoring , intermittent fasting can be safely integrated into diabetes management ( Grajower et al., 2019 ).

Research has also found that fasting increases hemoglobin oxygen-carrying capacity , improving metabolic function and reducing insulin resistance ( Horne et al., 2013 ). These findings highlight intermittent fasting as a powerful tool for controlling diabetes and enhancing overall health .

Turning Around Non-Healing Diabetic Wounds

Turning a chronic non-healing diabetic wound to a healing wound requires a comprehensive evaluation to identify and address the underlying causes. Many chronic wounds are linked to systemic conditions such as:

✔ Peripheral Vascular Disease – Poor circulation causing a chronic wound.

✔ Weakened Immune System – Reduces the body’s ability to fight infection.

✔ Anemia & Nutritional Deficiencies – Limits oxygen and essential nutrients needed for tissue repair.

✔ Unstable Diabetic Control – Fluctuating blood sugar impairs healing.

✔ Incorrectly Identified Infections – Delayed or ineffective treatment.

✔ Failure to Off-Load Pressure – Continuous stress on the ulcer site prevents closure.

With 30+ years of experience , Dr. Reed collaborates with top local specialists to resolve these barriers, working closely with:

✔ Vascular Surgeons & Vein Specialists – Restoring proper blood flow.

✔ Interventional Radiologists – Minimally invasive procedures for improved circulation.

✔ Infectious Disease Specialists – Targeting hard-to-treat infections.

✔ Endocrinologists & Diabetologists – Optimizing blood sugar control.

By addressing both the wound and its root causes , Dr. Reed provides a faster, more effective healing process —helping patients regain mobility and improve their quality of life.

THE 30 DAY ASSESSMENT

A key benchmark in Dr. Mark Reed’s wound care protocol is a 50% reduction in wound size within the first 30 days of treatment. If this milestone is not met, a comprehensive reassessment is conducted to identify and address any underlying factors interfering with healing. This proactive approach ensures that every wound continues to progress toward full recovery.

While national statistics indicate that diabetic wounds typically take 20 weeks to heal, Dr. Reed’s advanced treatment methods reduce healing time to just 6 to 10 weeks for most patients. His commitment to ongoing evaluation and treatment adjustments ensures optimal healing outcomes.

How Microcirculation Works During Walking

The capillary refill process plays a crucial role in keeping the skin of the feet oxygenated:

During walking, foot oxygenation follows a cyclical pattern :

✔ Foot Off the Ground → Capillaries refill, supplying oxygen.

✔ Foot on the Ground → Pressure blanches the skin, momentarily reducing oxygen flow.

This natural process is disrupted in diabetes , as impaired microcirculation delays oxygen replenishment , increasing the risk of ulcers.

The Four Phases of Wound Healing & Diabetes Impact

1. Hemostasis (Immediate Response)

�� Begins at injury → Platelets clot and blood vessels constrict to stop bleeding.

�� Platelets release growth factors that initiate healing.

2. Inflammatory Phase (0–4 Days)

�� White blood cells (Neutrophils, Macrophages, Leukocytes) rush to the wound to:

✔ Fight infection by killing bacteria

✔ Clear damaged tissue

�� These cells release secondary growth factors , attracting more immune cells to start tissue repair.

3. Proliferative Phase (4–14 Days)

�� Fibroblasts arrive to:

✔ Produce new collagen

✔ Create new blood vessels

✔ Repair damaged epithelial tissue

�� Osteoblasts build new bone and chondrocytes form scar cartilage.

4. Remodeling Phase (6 Months – 1 Year)

�� Fibroblasts strengthen tissue by increasing collagen production.

�� Osteoclasts & osteoblasts reshape bone under weight-bearing forces.

How Diabetes Disrupts Wound Healing

In diabetes mellitus , high blood sugar (hyperglycemia) causes protein glycation , leading to:

❌ Impaired oxygen delivery to tissues

❌ Neutrophils unable to exit blood vessels → Delayed infection response

❌ Reduced macrophage activity → Slower release of growth factors

❌ Poor capillary formation → Weakened connective & granulation tissue

�� Clinical Insight: Targeting microvascular health and improving oxygenation (e.g., vasodilators, optimized glucose control) can significantly enhance wound healing outcomes in diabetic patients.

Reversing Diabetic Microvascular Ischemia

Dr. Reed utilizes medications that improve microcirculation, including:
�� Nitroglycerin Therapy → Dilates small arteries, reversing glycation-induced ischemia.
�� Sildenafil & Tadalafil → Increase capillary oxygenation and circulation.

Long-term use of Nitroglycerin (up to a year) has been shown to:
✔ Reverse neuropathy
✔ Heal retinopathy
✔ Improve kidney function

By restoring oxygen flow to the feet, these treatments reduce ulcer risk, improve healing, and help prevent severe diabetic complications.

Gangrene & Diabetes: Risks, Symptoms, and Treatment

Gangrene occurs when there is a loss of blood supply to an area of skin, often due to poor circulation or bacterial infection . It is most common in diabetic patients with circulatory issues in the feet and toes . A sudden onset of foot pain, cold skin, and color changes may indicate a critical blockage of blood flow , requiring immediate medical attention .

Diabetic neuropathy further increases the risk by reducing pain sensation, meaning injuries like ingrown toenails or minor cuts can go unnoticed, leading to infection, gangrene, and potential amputation .

Types of Gangrene & Treatment

1. Dry Gangrene (Non-Infected)

• Assessment: A Wound Care Specialist evaluates the condition with X-ray or MRI to rule out gas gangrene.

• Treatment: Often managed with povidone-iodine desiccants to keep tissue infection-free until it naturally sloughs off.

2. Wet Gangrene (Infected) & Gas Gangrene

• Signs: Severe redness, swelling, pus, fever, weakness , and a rapidly spreading infection. Gas gangrene can develop, caused by flesh-eating bacteria like Hemolytic Streptococcus, which has a 94% mortality rate if untreated .

• Treatment: Requires immediate surgery to remove infected tissue, IV antibiotics, hyperbaric oxygen therapy , and, in severe cases, bypass surgery to restore circulation .

Urgency of Treatment

Wet or gas gangrene is a life-threatening emergency . Without immediate medical intervention, it can lead to amputation or death . Early detection, proper wound care, and circulation assessments are crucial to prevent severe complications.

Diabetic Charcot Foot

mark.reed.dpm@gmail.com (Mark Reed) — Thu, 03 Apr 2025 23:10:01 GMT

Diabetic Charcot Foot

Diabetic Charcot Foot: Causes, Symptoms, and Treatment

Charcot foot is a serious, non-infectious, degenerative condition that affects the bones, joints, and soft tissues of the foot and ankle, primarily in people with diabetes. It occurs in approximately 1% to 2.5% of diabetic individuals, and its prevalence has been rising as people with diabetes live longer. This condition affects both men and women equally, with an average onset age of 40. Additionally, about 30% of cases involve both feet and/or ankles.

What Happens in Charcot Foot?

Charcot foot can develop suddenly and, in some cases, without pain. Within a short period, the bones in the foot or ankle may weaken, spontaneously fracture, and fragment. As the condition progresses, it leads to severe foot deformity, often making it difficult to wear standard footwear.

One of the hallmark signs of Charcot foot is the collapse of the arch, resulting in a characteristic “rocker-bottom” foot shape. As the foot loses its normal structure, areas of high pressure form on the sole, making it prone to ulcers and open sores. Additionally, ankle instability may become so severe that walking without a brace becomes difficult or even impossible.

Treatment Options

Most cases of Charcot foot can be managed without surgery using:

• Custom braces and splints

• Special orthopedic footwear

• Total contact casting to stabilize the foot and prevent further deformity

Advancements in medical technology have expanded the range of non-surgical treatment options, allowing for better management of Charcot foot.

When is Surgery Necessary?

In some cases, surgical intervention may be required, particularly when:

1. The deformity causes significant instability that cannot be managed with bracing.

2. Increased pressure on the sole of the foot raises the risk of ulcers.

3. Chronic ulcers develop due to severe foot deformity and do not heal with conservative treatment.

4. Ulcers repeatedly return despite successful non-surgical management.

Why Early Detection Matters

Recognizing Charcot foot early is crucial to preventing severe complications. If you have diabetes and notice swelling, warmth, or changes in foot shape, seek medical attention immediately. Prompt treatment can help maintain mobility and reduce the risk of serious deformities.

Charcot Foot Surgical Correction

Charcot Foot is a serious condition that can lead to severe deformity, ulceration, and even amputation if left untreated. Surgical intervention is often required in advanced cases to stabilize the foot and restore function. The type of surgery depends on several factors, including:

Location of the Charcot deformity (midfoot, ankle, etc.)
Stage of the Charcot process (three defined stages)
Presence of an ulcer
Stability of the deformity
Patient’s overall health

Types of Surgical Procedures

Ostectomy

Purpose: Removes a bony prominence causing excessive pressure and ulceration.
Procedure: Outpatient or one-night hospital stay; local or general anesthesia.
Recovery: 3-4 weeks in a weight-bearing brace or cast, followed by extra-depth diabetic footwear.

2 . Midfoot Realignment Arthrodesis

Purpose: Used for significant midfoot instability and collapsed arches.
Procedure: Hospital stay (1-2 nights), general anesthesia, internal fixation (plates/screws).
Recovery:
3 months in a non-weight-bearing cast
1-2 months in a weight-bearing brace
5-6 months before returning to extra-depth diabetic footwear

3. Hindfoot and Ankle Realignment Arthrodesis

Purpose: Limb salvage procedure for severe instability when bracing has failed.
Procedure:
1-2 night hospital stay, general anesthesia
Use of screws, plates, nails, and external fixators for stabilization
Recovery:
4 months in a non-weight-bearing cast
2-3 months in a protective rocker-bottom brace
Progression to a custom-made brace for long-term support

Potential Complications

Increased risk of infection due to diabetes-related immune suppression
Higher failure rates in arthrodesis procedures compared to minor surgeries
Longer recovery periods with an increased risk of post-surgical complications
Limb loss in cases of severe infection or non-healing wounds

Patient Considerations Before Surgery

Extensive Consultation: Discuss risks and benefits thoroughly with a surgeon.
Preoperative Assessment: Cardiac and overall health evaluation before surgery.
Postoperative Care: Long-term commitment to protective footwear and braces.

Why Choose Surgical Management?

While surgery for Charcot Foot carries risks, it is often the only alternative to below-the-knee amputation. Successful procedures can restore mobility, reduce pain, and improve overall quality of life. It is crucial to seek treatment from an experienced specialist, preferably at a tertiary care facility with expertise in diabetic foot conditions.

THE PATHOPHYSIOLOGY OF DIABETES, AND IMPACT ON TISSUE DAMAGE & VASCULAR HEALTH

The effects of diabetes mellitus on the body are complex, but the primary mechanism of tissue damage is protein glycation . This process occurs when excess glucose enters cells, drawing in water and causing osmotic swelling. The result is arteriole constriction, reduced oxygen delivery, and eventual cell dysfunction or death.

How Diabetes Affects the Body

�� Blood Vessels (Diabetic Angiopathy):

The smooth muscle cells in arteriole walls absorb glucose without insulin, leading to arteriole constriction and reduced capillary oxygen delivery.

�� Nerves (Diabetic Neuropathy):

High glucose levels convert into aldose reductase, which damages Schwann cells in nerves, leading to nerve dysfunction and loss of sensation.

�� Kidneys (Diabetic Nephropathy):

Glycation in the kidneys causes albumin leakage from glomeruli, leading to proteinuria and elevated creatinine, which can progress to kidney failure.

�� Eyes & Capillary Damage (Diabetic Retinopathy):

Similar osmotic glycation damage occurs in the retina, which can lead to blindness if left uncontrolled. Excess glucose is converted into sorbitol, which damages capillaries and causes oxygen loss and albumin leakage—a major factor in chronic wounds.

Why Diabetics Are at High Risk for Foot Ulcers

The plantar skin of the feet requires significant oxygen supply , making it highly vulnerable to diabetic foot ulcers due to diabetic angiopathy (vascular damage) .

The feet, eyes, kidneys, and nerves are among the body’s most oxygen-dependent tissues.

Because diabetic vascular disease reduces oxygen delivery, diabetic foot ulcerations, neuropathy, nephropathy, and retinopathy are common complications.

Managing blood sugar levels, improving circulation, and utilizing advanced wound care treatments are critical for prevention and treatment of diabetes-related complications.

Understanding these mechanisms, and e arly intervention can help preserve vascular health, nerve function, and organ integrity.

THE PATHOPHYSIOLOGY OF DIABETIC FOOT WOUNDS - ULCERS

Diabetic foot ulcers result from diabetes-induced microvascular damage (diabetic angiopathy), where glycation restricts oxygen flow to the skin, leading to tissue breakdown. This lack of oxygen causes tissue breakdown, making the feet vulnerable to ulceration and slow healing.

The Capillary Return Test (CPT) & Its Importance

The CPT test evaluates how quickly blood flow returns to the skin:

�� Hallux (Big Toe): Normal = Color returns in under 1 second

�� First Metatarsal: Normal = Instantaneous color return

�� Diabetic Patients: Delayed CPT = Microvascular impairment

✅ Normal CPT:

Under the big toe (hallux) → Color returns in <1 second

Under the first metatarsal → Color returns almost instantly
✅ Diabetics typically have delayed CPT, indicating poor microcirculation and increased risk of ulcers.

Why Wound Healing Is Impaired in Diabetes

Hyperglycemia (high blood sugar) causes protein glycation, restricting oxygen supply.
Neutrophils (first responders) cannot escape the blood vessels to fight infection.
Macrophages fail to release proper growth factors, preventing fibroblast activation.
New capillary and tissue formation is significantly delayed, leading to chronic wounds.

This impaired healing process explains why diabetic foot ulcers are slow to recover and require specialized treatment approaches to restore proper function.

➡️ Dr. Reed’s advanced wound care protocols address these underlying diabetic complications, promoting faster and more effective healing.

HOW DIABETES EFFECTS FIGHTING INFECTIONS AND WOUND HEALING

Hyperglycemia, or high blood sugar, has two major effects on the wound healing process that contribute to poor healing and increased risk of complications, such as infection and amputations.

1. Restricted Microvascular Flow

Glycation caused by excess glucose constricts the arterioles, reducing blood flow to the injured tissue.
Under normal conditions, arterioles dilate to ensure proper blood supply when a wound occurs. However, in diabetic patients, this restricted blood flow prevents the release of essential growth factors (such as platelet-derived growth factor), which are critical to initiate wound healing.
As a result, the wound becomes stagnant, prone to infection, and unable to progress through the necessary healing stages.
Oral antibiotics and basic wound care (like bandage changes) often fail to address the root cause, leading to deep bone infections (osteomyelitis) and amputations.

2. Leukocyte Dysmotility

Leukocytes (white blood cells), which are crucial for fighting infection and clearing dead tissue, become enlarged due to excessive glucose.
This dysmotility prevents these cells from properly migrating out of the arteriole walls to the site of injury.
The inability of white blood cells to reach the wound site leads to poor infection control and delayed tissue repair.
Without proper immune response, the wound is more susceptible to infection, and the infection can spread, threatening deeper tissues, including the bones.

Supporting Studies:
Spampinato SF, et al. 714-528-3668: Discusses the treatment of impaired wound healing in diabetes, emphasizing the role of old drugs. (Pharmaceuticals (Basel). 2020 Apr 1; 13(4):60)
Pezhman L, Tahrani A, Chimen M. 714-528-3668: Explores dysregulation of leukocyte trafficking in Type 2 diabetes and potential therapeutic avenues. (Front Cell Dev Biol. 2021 Feb 22; 9:714-528-3668

These two key issues—restricted blood flow and impaired immune response—lead to wound stagnation, increased risk of infection, and potential for osteomyelitis (bone infection), which is why wounds in diabetic patients often fail to heal and may ultimately require amputation.

By addressing these underlying issues, advanced wound care treatments like microvascular vasodilation and wound stimulation technologies can help reverse these complications and promote healing.

DIABETIC NEUROPATHY (DNP) CHALLENGES AND NITROGLYCERIN

Diabetic neuropathy remains one of the most significant and challenging complications of diabetes. It typically manifests as neuropathic pain or numbness in the extremities, which often significantly impacts the quality of life.

Neuropathy pain and numbness remain major complications of diabetes, often resistant to traditional treatments like Lyrica or Gabapentin, which only mask pain and can cause sleep disturbances.

For over 33 years, Dr. Mark Reed has used nitroglycerin patches to increase microcirculation in the lower extremities, reversing oxygen ischemia—similar to its effect in treating angina. Applied for 12 hours daily , these patches have been highly effective in reducing or eliminating radiating burning pain in the feet.

Additionally, for wound healing , Dr. Reed places an extra patch near the ulcer to increase oxygenation , improve white blood cell migration , and accelerate tissue repair . Research supports the significant pain reduction achieved with transdermal nitroglycerin. (Taheri A, Farbood et al., J Diabetes Metab Disord, 2015).

Traditional Treatments

Common medications for diabetic neuropathic pain include Lyrica and Gabapentin. While these drugs can provide pain relief, they mask the symptoms rather than addressing the root cause.
These medications are non-narcotic pain relievers but are often associated with side effects such as sleep disturbances and other complications.

Nitroglycerin for Neuropathy and Wound Healing

A breakthrough treatment that addresses the root cause of diabetic neuropathy involves Nitroglycerin, which has been used for over 75 years to treat oxygen ischemia in conditions like angina pectoris through microcirculatory vasodilation.
Dr. Mark Reed has successfully employed transdermal Nitroglycerin patches for over 33 years to improve microcirculation in the lower extremities.
The patches are worn for 12 hours a day and help reverse the ischemic effects in the feet, significantly reducing or even eliminating the burning pain often associated with diabetic neuropathy.
Studies, such as those by Taheri et al., have demonstrated the pain-reducing effects of transdermal Nitroglycerin for diabetic peripheral neuropathy.

Nitroglycerin's Role in Wound Healing

In addition to pain relief, Nitroglycerin is used to enhance oxygenation in the area surrounding diabetic foot ulcers.
The increased oxygen supply helps improve white blood cell migration to the wound, boosting infection control and stimulating healing.
By applying an additional patch proximal to the ulcer, the treatment helps the body naturally promote healing by enhancing the oxygen delivery to tissues involved in the wound healing process.

This approach offers a more comprehensive solution for managing both neuropathic pain and chronic wound healing in diabetic patients, addressing the underlying circulatory issues rather than just masking symptoms. For more information click here!

DIABETES AND LARGE VESSEL PERIPHERAL VASCULAR DISEASE

In 50% of diabetic patients , large vessel disease (atherosclerosis) occurs alongside microvascular damage caused by hyperglycemia. This condition results from atherosclerotic plaque —a buildup of fibrous material, lipids, and cholesterol—often affecting arteries in the thigh and below the knee , increasing the risk of limb loss .

Atherosclerosis worsens oxygen deprivation in the feet by restricting blood flow to the microcirculation (arterioles and capillaries) , compounding the effects of diabetes-induced ischemia. Every diabetic patient with weak pulses or neuropathy should be screened for peripheral vascular disease (PVD) . If arterial Doppler studies and ankle-brachial index (ABI) tests indicate reduced circulation, revascularization may be required.

A simple analogy: Large arteries are like the main water pipe supplying a house, while arterioles are the smaller pipes leading to faucets. Diabetes constricts these smaller vessels , preventing oxygen delivery. Nitroglycerin patches help by dilating arterioles, restoring oxygen flow to tissues , reducing complications, and improving healing.

Atherosclerotic Disease in Diabetes

In addition to the well-known effects of hyperglycemia on the microcirculation, diabetic patients often experience large vessel disease (LVD) due to atherosclerosis.

Atherosclerosis in diabetics accelerates due to factors such as chronic high blood glucose, which contributes to the formation of plaques in the arteries. These plaques consist of a fibrous cap that overlying a core of necrotic cellular debris, foam cells, lipid, and cholesterol crystals. Atherosclerosis typically begins at the trifurcation below the knee, impacting arteries like the popliteal artery, which can restrict blood flow to the lower extremities.

The Impact on Diabetic Patients

Atherosclerosis causes thickening or hardening of the arteries, resulting in arterial occlusion or narrowing that severely restricts blood flow to tissues.
This is compounded in diabetic patients, who already have microvascular damage due to hyperglycemia-induced glycation, leading to oxygen ischemia in tissues like the feet.
The combination of large vessel disease and microvascular damage places diabetic patients at high risk of limb loss due to inadequate blood supply, impaired tissue healing, and increased risk of infection.

Pathophysiology Analogy

An analogy to understand this vascular compromise is comparing the human circulation system to plumbing:

Large Arteries = Main six-inch pipe supplying water to the house. These large vessels are impacted by atherosclerosis but not by hyperglycemia.
Arterioles and Capillaries = Smaller three-quarter inch pipes supplying water to faucets. These smaller vessels are impacted by hyperglycemia-induced microvascular damage, leading to vasoconstriction and impaired oxygen delivery.

In diabetes, the smaller pipes (arterioles) become constricted due to glycation, restricting blood flow to the tissues. Nitroglycerin works as a vasodilator, helping to relax the constricted arterioles and improve oxygenation to the tissues.

Screening for Peripheral Arterial Disease (PAD)

Given the significant risk of large vessel disease in diabetic patients, it’s essential to screen for peripheral vascular disease (PVD), which is commonly associated with poorly palpable pulses or diabetic neuropathy. The following diagnostic tools help identify PAD:

Arterial Doppler Study: This test helps assess blood flow in the arteries of the legs.
Ankle-Brachial Index (ABI): The comparison of blood pressure in the arm to the ankle or toe can help identify abnormalities in blood flow and confirm the presence of PVD.
Referral for Revascularization: If ABI or doppler results are abnormal, a vascular specialist should evaluate the patient for potential revascularization to restore blood flow to the affected tissues and prevent limb loss.

This comprehensive approach to understanding and managing diabetic vascular disease underscores the importance of identifying both microvascular and large vessel issues in order to provide effective treatment and prevent severe complications like limb amputation.

UNDERSTANDING GLYCATED HEMOGLOBIN (HBA1C) MONITORING

Glycated hemoglobin ( HbA1c ) is a key marker for assessing osmotic microcirculation ischemic cell damage from high blood sugar ( glycation ). Since red blood cells have a 120-day lifespan , HbA1c provides a reliable measure of medium-term blood sugar control in diabetes.

The goal for diabetic patients is to maintain HbA1c below 6 , achieving diabetic remission —a state where microcirculation damage is minimized . This helps prevent serious complications , including:

✅ Diabetic foot ulcers

✅ Neuropathy (nerve damage)

✅ Retinopathy (vision loss)

✅ Nephropathy (kidney disease)

✅ Cardiopathy (heart disease)

Monitoring and controlling HbA1c levels is essential for long-term health and complication prevention in diabetes.

One of the most important assessments of diabetic osmotic microcirculation ischemic cell damage from hyperglycemia (glycation) is the damage occurring in the red blood cells by measuring glycated hemoglobin . The Red blood cells have a consistent lifespan of 120 days and are accessible for measurement of amount of damage occurring to cells as glycated hemoglobin . Measurement of HbA1c that is the predominant form of glycated hemoglobin, enables medium-term blood sugar control to be monitored in diabetes . The goal of every diabetic patient is to have their glycated hemoglobin results to below 6 that would place a diabetic patient in what is defined as “diabetic remission” where the effects of damaging tissues from microcirculation ischemia would be controlled to prevent the long-term complications of diabetic foot ulcerations, retinopathy, neuropathy, nephropathy and cardiopathy.

Understanding Glycated Hemoglobin (HbA1c)

Glycated hemoglobin (HbA1c) is a critical marker in monitoring long-term blood glucose control in diabetic patients. Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body. When blood glucose levels are high, glucose molecules bind to hemoglobin, forming glycated hemoglobin (HbA1c). This process is known as glycation, which can lead to cellular damage in various tissues.

HbA1c Test: The HbA1c test measures the percentage of hemoglobin that has glucose attached to it, reflecting the average blood sugar levels over the past 2-3 months. Since red blood cells have a lifespan of about 120 days, the HbA1c provides a reliable measure of medium-term blood sugar control.
Normal HbA1c Levels: For most individuals, the normal range for HbA1c is typically between 4% and 5.6%. Diabetic patients should aim for a target HbA1c level of below 6%, which is considered diabetic remission.

Diabetic Remission and Its Importance

Achieving an HbA1c level below 6% indicates good blood sugar control and suggests that microvascular damage caused by hyperglycemia (such as glycation-induced ischemia) is being minimized.
Maintaining an HbA1c level below 6% is associated with a reduced risk of developing long-term complications of diabetes , including:
Diabetic foot ulcerations
Retinopathy (damage to the eyes)
Neuropathy (nerve damage)
Nephropathy (kidney damage)
Cardiopathy (heart disease)

The Goal of Diabetic Remission

The ultimate goal of diabetes management is to achieve diabetic remission, where blood sugar levels are well-controlled, and the damaging effects of microvascular ischemia (caused by hyperglycemia and glycation) are minimized. This helps to prevent or delay the onset of complications like foot ulcers, nerve damage, and other vascular complications.
Aiming for HbA1c below 6% requires a combination of consistent blood sugar monitoring, medication, lifestyle changes (including diet and exercise), and sometimes specialized treatments to reduce glycation effects on tissues.

By achieving diabetic remission through careful control of HbA1c levels, diabetic patients can significantly reduce their risk of long-term complications, improving overall quality of life and health outcomes.

WOUND TYPES

OC Center for Wound Healing & Foot Care addresses a wide range of wound types, each requiring specific care and treatment protocols to ensure optimal healing. The following are the types of ulcers and wounds commonly treated:

1. Diabetic Wounds

Diabetic foot ulcers are common among individuals with diabetes due to the microvascular damage caused by hyperglycemia. These wounds often occur in areas of pressure or trauma, and effective management includes controlling blood glucose levels, promoting circulation, and managing infection.

2. Pressure Ulcers (Bedsores)

Caused by prolonged pressure on the skin, usually in immobile patients, these ulcers can range from mild skin damage to deep, necrotic tissue. Treatment involves relieving pressure, improving circulation, and preventing infection.

3. Venous Stasis Ulcers

Typically seen in individuals with chronic venous insufficiency, these ulcers often occur on the lower legs. They result from poor circulation and are often treated with compression therapy, as well as managing any underlying venous disease.

4. Skin Lacerations

Lacerations caused by trauma, accidents, or surgical procedures can be treated by cleaning, debridement, and suturing or using other wound closure methods. Infection prevention is crucial.

5. Traumatic Injuries

Any injury from accidents, falls, or other physical trauma that results in broken skin or deeper tissue damage is treated with appropriate wound cleaning, debridement, and sometimes surgical repair to ensure proper healing.

6. Ischemic Ulcers with or without Gangrene

Ischemic ulcers are caused by poor blood flow due to narrowed or blocked arteries (often due to atherosclerosis). If left untreated, these ulcers can progress to gangrene (tissue death). Treatments often involve revascularization procedures or amputation if gangrene has set in.

7. Post-Surgical Incision Wounds

After surgery, patients may develop wounds or incisions that require specialized care to prevent infection and promote healing. This includes careful dressing changes and monitoring for signs of infection or complications.

8. Infected Wounds

Infected wounds can result from surgical procedures, trauma, or chronic conditions like diabetes. They require appropriate antibiotics, wound cleaning, and debridement to remove dead tissue and promote healthy tissue regeneration.

9. Post-Cancer Radiation Wounds

Radiation therapy for cancer can cause skin damage, leading to radiation burns or wounds that require special care to soothe, heal, and prevent further damage. Treatment often includes topical ointments, wound dressings, and managing the underlying radiation effects.

10. Lymphedema Ulcerations

Lymphedema, which causes swelling in the limbs due to fluid accumulation, can lead to ulcerations. Treatment often involves compression therapy, elevation, and careful management of skin integrity to prevent infection and further injury.

11. Burn Wounds

Burns, depending on severity, require immediate cooling, cleaning, and dressing. Severe burns may need more complex treatments such as skin grafts or surgical repair to promote healing.

Treatment Protocols for Various Ulcers

Each of these wound types has specific care requirements to promote healing and prevent complications like infection or tissue death. OC Center for Wound Healing & Foot Care utilizes advanced technologies such as negative pressure wound therapy, hyperbaric oxygen therapy, and skin grafts in combination with traditional wound care methods to optimize healing outcomes for each patient.

WOUND CARE TYPES OF TREATMENT

Wound Care Interventions for Chronic Wounds

Effective wound care involves a variety of therapeutic interventions designed to promote healing and address underlying factors contributing to wound stagnation. These treatments are used when a wound has not shown significant healing after 30 days or when chronic conditions complicate the healing process, such as diabetic ulcers, pressure sores, or venous stasis ulcers. Below are the advanced treatments commonly utilized:

1. Topical Wound Medications

Purpose: Prevents bacterial growth and infection in the wound.
Examples: Antiseptic creams, antibiotics, or silver sulfadiazine can be applied to minimize bacterial contamination and promote a sterile environment.

2. Hydrogel Dressings

Purpose: Maintains moisture balance in the wound and allows observation of exudate drainage.
Benefit: These dressings are ideal for wounds with dry or necrotic tissue and help promote healing by preventing desiccation of the wound bed.

3. Debridement

Purpose: Removal of non-viable, infected, or necrotic tissue from the wound site.
Benefit: Promotes the release of platelet-derived growth factors (PDGF) and enables the wound to enter the next phase of healing by preparing the tissue bed for new tissue growth.

4. Skin Substitutes (e.g., Amniotic Membrane Grafts)

Purpose: These biologic dressings provide a scaffold for tissue regeneration.
Benefit: They offer temporary protection and support while encouraging tissue growth and reducing the chance of infection.

5. Off-Loading (e.g., Total Contact Cast, Walking Cast, or Pneumatic Walking Boot)

Purpose: Reduces pressure on the ulcerated area, improving circulation and oxygenation.
Benefit: These devices help re-establish proper blood flow to the affected tissues, promoting healing, particularly in diabetic foot ulcers.

6. Hyperbaric Oxygen Therapy

Purpose: Increases oxygen concentration in tissues by having the patient breathe 100% oxygen in a pressurized chamber.
Indication: Only used for chronic, diabetic osteomyelitis (bone infection).
Benefit: Enhances the body’s ability to fight infection and promotes the healing of difficult-to-treat wounds.

7. Nitroglycerin / Sildenafil Citrate (Arteriole Dilators)

Purpose: These medications dilate the arterioles, increasing oxygenated blood flow to the wound site.
Benefit: This is particularly effective for improving microcirculation in diabetic ulcers, enhancing the oxygenation needed for tissue repair and reducing pain.

8. Wound Vacuum Assisted Closure (VAC)

Purpose: Uses negative pressure to promote the formation of granulation tissue and reduce wound size.
Benefit: Encourages tissue growth, reduces edema, and aids in the closure of chronic wounds over fascia, muscle, tendon, and bone.

9. Platelet-Derived Growth Factors (PDGF)

Purpose: Derived either from the patient's own blood or through recombinant technology (yeast-based), these growth factors stimulate tissue regeneration and wound healing.
Benefit: PDGF accelerates the inflammatory phase of wound healing, stimulates cell proliferation, and enhances the formation of new blood vessels.

10. Autologous Skin Graft Transfers

Purpose: Uses the patient’s own healthy skin to cover the wound, providing a natural barrier to infection.
Benefit: Promotes quicker healing and minimizes the risk of rejection or allergic reactions, as the graft is from the patient’s own body.

11. Sliding Metatarsal Head Osteotomy

Purpose: A surgical procedure to rebalance pressure across the metatarsals, typically done in diabetic patients with foot deformities.
Benefit: Helps distribute the forces during walking, reducing the formation of pressure ulcers and improving foot function.

12. Percutaneous Achilles Tendon Lengthening

Purpose: A procedure to lengthen the Achilles tendon to off-load pressure from the forefoot.
Benefit: Helps prevent or treat ulcers caused by excessive pressure and deformities in the foot.

13. Compressive Dressings

Purpose: Reduces edema (swelling) and helps the wound heal by applying a uniform, controlled pressure.
Benefit: Particularly useful for venous ulcers and other types of wounds where edema is a contributing factor to delayed healing.

14. Gradient Compression Stockings

Purpose: Reduces lymph edema and enhances blood flow in patients with chronic venous insufficiency or lymphatic issues.
Benefit: These stockings help reduce swelling, improve circulation, and support the healing of ulcers.

Each wound type and patient condition requires an individualized treatment plan, which may involve one or several of the above advanced wound care interventions. The goal is to optimize tissue healing by addressing the underlying causes of the wound, improving circulation, and preventing infection, all while minimizing the risks of complications like osteomyelitis or amputation.

GANGRENE

Gangrene is the death of tissue due to a loss of blood supply or severe bacterial infection. The most common type, dry gangrene, occurs in patients with diabetes mellitus who also have peripheral arterial disease (PAD), leading to poor circulation in the feet and toes.

Other contributing factors include:

Atherosclerosis: Plaque buildup in arteries that restricts blood flow.
Diabetic Neuropathy: Nerve damage that reduces pain perception, making injuries go unnoticed.
Infections: Open sores, ulcers, or injuries that develop bacterial infections due to impaired immune response in diabetics.
Sudden Blockage of Blood Flow: A sudden clot in an artery (acute ischemia) leading to immediate tissue death.

Warning Signs of Gangrene

Pain and Skin Changes: Sudden onset of pain in the feet or legs, though diabetics with neuropathy may not feel pain.
Temperature Decrease: Affected areas become cold to the touch due to reduced blood supply.
Skin Color Changes:
Early signs: Red or purple discoloration.
Progression: Dark brown or black tissue, indicating necrosis (tissue death).
Foul Odor: Associated with wet gangrene, which involves bacterial infection and tissue liquefaction.
Blisters and Sores: Open wounds that do not heal and become infected.

Diabetic Neuropathy and Increased Risk

Diabetic neuropathy causes a loss of sensation in the feet, leading to unnoticed injuries. For example:

A minor ingrown toenail can go undetected, worsening into an infection.
Without pain perception, a diabetic foot ulcer may develop and lead to tissue necrosis.
Poor circulation impairs wound healing, increasing the risk of gangrene and amputation.

Medical Urgency

Immediate attention is required if there are signs of sudden ischemia (such as cold, painful, or discolored feet).
Surgical intervention (angioplasty or bypass surgery) may be necessary to restore circulation.
If gangrene progresses, amputation may be needed to prevent systemic infection (sepsis).

Prevention Strategies

Blood Sugar Control: Keeping HbA1c below 6.0 reduces the risk of vascular complications.
Daily Foot Inspections: Checking for cuts, blisters, or color changes.
Proper Footwear: Avoiding tight shoes that cause pressure points.
Regular Circulation Assessments: Capillary refill time (CPT) and Doppler studies to check for PAD.
Prompt Wound Care: Treating minor injuries early to prevent infections.
Vasodilators: Medications such as nitroglycerin or sildenafil to improve microcirculation.

Gangrene is a serious complication, but early intervention and strict diabetes management can prevent limb loss and life-threatening infections.
