Treatment of Non-Healing Wounds Secondary to Hansen's Disease

Antimicrobial Treatment for Hansen's Disease

• The World Health Organization recommends multidrug therapy (MDT) for multibacillary leprosy, consisting of rifampin 600mg monthly supervised, clofazimine 300mg monthly supervised plus 50mg daily unsupervised, and dapsone 100mg daily for 12-24 months, according to the World Health Organization 1
• Treatment with MDT should be continued during wound healing and not interrupted due to skin complications, as advised by the World Health Organization 1
• Screening for G6PD deficiency is necessary before initiating dapsone due to the risk of hemolytic anemia, as recommended by the World Health Organization 1
• Regular monitoring of complete blood count and liver function tests is required during dapsone therapy, according to the World Health Organization 1

Wound Care Management

• Prompt management of foot infections with antibiotics and surgical debridement is necessary if abscess, gas, or necrotizing fasciitis is present, as recommended by the American College of Cardiology 2
• Bacterial and fungal cultures should be taken from three areas of the wound, particularly sloughy or crusted areas, on alternate days, according to the British Association of Dermatologists 3
• Regular debridement to remove necrotic tissue and biofilm is essential, using techniques such as surgical, sharp, autolytic, mechanical, or enzymatic methods, as recommended by the American College of Cardiology 2
• Wounds should be cleansed regularly by irrigating gently with warmed sterile saline or chlorhexidine (1:5000 dilution), according to the British Association of Dermatologists 3
• A greasy emollient (50% white soft paraffin with 50% liquid paraffin) should be applied over the entire epidermis, including denuded areas, as recommended by the British Association of Dermatologists 3
• Topical antimicrobial agents should be used on sloughy areas only, considering silver-containing products/dressings guided by local microbiology, according to the American College of Cardiology and the British Association of Dermatologists 2, 3
• Non-adherent dressings should be applied to denuded dermis, such as Mepitel or Telfa, with secondary foam or burn dressing to collect exudate, as recommended by the British Association of Dermatologists 3
• Maintaining a moist wound bed while controlling drainage and avoiding tissue maceration is crucial, according to the American College of Cardiology 2

Pressure Offloading

• Proper pressure offloading for plantar ulcers is necessary to minimize excessive or persistent pressure at the wound site, as recommended by the American College of Cardiology 2
• This is individually tailored and critical for tissue growth, particularly in neuropathic wounds from Hansen's disease, according to the American College of Cardiology 2

Infection Management

• Systemic antibiotics should only be administered if clinical signs of infection are present, not prophylactically, according to the British Association of Dermatologists 3
• For established infection, broad-spectrum coverage with antibiotics such as amoxicillin-clavulanate, piperacillin-tazobactam, or carbapenems is recommended, as advised by the Infectious Diseases Society of America 5, 6
• Surgical debridement is mandatory for deep infections involving bone, joints, or soft tissue abscesses, according to the American College of Cardiology 2

Medical Optimization

• Smoking cessation is crucial for promoting wound healing, as recommended by the American College of Cardiology 2
• Glycemic control is necessary if the patient is diabetic, according to the American College of Cardiology 2
• Cardiovascular risk factor modification is essential, as recommended by the American College of Cardiology 2
• Nutritional support with 20-25 kcal/kg daily during the catabolic phase and 25-30 kcal/kg daily during recovery is necessary, according to the British Association of Dermatologists 3

Monitoring for Leprosy Reactions

• Leprosy reactions should be distinguished from treatment failure, and MDT should be continued while adding anti-inflammatory therapy, as recommended by the World Health Organization 1
• Type 1 reversal reactions should be treated with corticosteroids while continuing MDT, according to the World Health Organization 1

Follow-up and Surveillance

• Wound healing progress should be assessed at regular intervals, expecting lesion flattening by 4-6 weeks after treatment initiation, as recommended by the World Health Organization 1
• Monitoring for drug toxicity, including liver function and complete blood count, is necessary, according to the World Health Organization 1
• ECG monitoring for QT interval is required when using clofazimine, especially with other QT-prolonging medications, as recommended by the World Health Organization 1
