Multimodal Care effective for Chronic Leprosy Ulcers, Suggests Review

Driven by peripheral neuropathy and vascular impairment, leprosy ulcers affect 60% of patients at diagnosis and cause major socioeconomic distress. To bridge the clinical gap identified in the 2019 Cochrane review, Dr. Muslimin and his Diponegoro University team synthesized current therapeutic modalities to optimize management strategies.

Therefore, the comprehensive review analyzed English-language randomized controlled trials, systematic reviews, and case reports from 1982 to 2025 across major databases like PubMed and Scopus. It evaluated topical, physical, off-loading, and preventive modalities, prioritizing clinical endpoints such as granulation tissue formation and healing time. Findings were systematically categorized into four therapeutic domains, with evidence quality graded from high to very low to establish clear, evidence-based recommendations for clinical practice.

Key Clinical Findings of the Review Includes:

• Robust Off-loading: The analysis confirmed that Total Contact Casting (TCC) and Molded Double-Rocker Plaster (MD POP) shoes offer the most robust evidence-based protection for redistributing plantar pressure, with non-infected neuropathic ulcers achieving a median healing time of approximately 34 days in the review.

• Topical Adjuncts: Phenytoin demonstrated significant clinical utility in accelerating the development of healthy granulation tissue and reducing fluid discharge more effectively than standard saline dressings, earning a moderate-to-high evidence rating in the review.

• Metabolic Support: Topical insulin emerged as a viable, cost-effective treatment that significantly accelerates wound healing and shortens the time to complete closure compared to placebo saline dressings, as per the review.

• Surgical Efficacy: Reconstructive techniques, specifically the use of fascio-cutaneous island flaps for weight-bearing heel areas, maintain a strong recommendation status for managing chronic ulcers and preventing disability according to the review.

• Hygiene Standards: While Sodium Chloride 0.9% (NaCl 0.9%) remains a fundamental component for basic wound hygiene and bed preparation, the review found very low certainty for its effectiveness as a standalone curative modality.

The results suggest that managing these chronic conditions effectively requires a comprehensive, multimodal approach where evidence-based interventions like total contact casting are combined with adjuncts such as phenytoin or insulin to optimize healing. This integration of diverse strategies across the identified therapeutic domains appears most promising for improving long-term patient outcomes despite the varying levels of scientific certainty for individual treatments.

Thus, the review concludes clinicians should consider the routine integration of validated off-loading techniques and cost-effective topical agents like phenytoin to improve recovery trajectories for patients suffering from anesthetic foot complications.

While the review offers a thorough synthesis of existing treatments, the overall low certainty of current data indicates a vital need for further large-scale, high-quality meta-analyses to establish more rigorous international clinical protocols.
