Study Profile
- Design
- single-patient case study (60-year-old woman with grade 5 diabetic foot ulcer facing imminent amputation; Jamia Hamdard, New Delhi, India)
- Sample size (n)
- 1
- Intervention
- Unani blood purifier + deobstruent medication, unripe papaya wound dressing, hirudotherapy weekly for ~3.5 months
- Comparator
- Conventional treatment trajectory toward amputation
- Primary endpoint
- Wound healing, pain control, limb salvage from amputation
- Primary result
- Pain score decreased from 80mm to 0-10mm on 100mm VAS within 20 days; necrotic areas disappeared and wound completely healed within 3.5 months; limb salvaged from imminent amputation
- Follow-up duration
- 3.5 months active treatment + observation
- PMID
- 24809835
Key Findings
- Limb salvage achieved in grade 5 diabetic foot facing imminent amputation
- Pain reduction from 80mm to 0-10mm VAS within 20 days
- Complete wound healing within 3.5 months
- Combination Unani + hirudotherapy + papaya dressing protocol
- No adverse events reported
Limitations
- Single patient - no generalizable conclusions possible
- Cannot separate effects of Unani medicine vs hirudotherapy vs papaya
- No long-term follow-up reported
- Subjective pain assessment
- Publication bias toward dramatic case successes
Clinical Implications
Zaidi 2014 provides hypothesis-generating evidence for hirudotherapy as adjunct in advanced diabetic foot ulcer management. For US clinicians under K040187, this Indian Unani-medicine case suggests potential utility in non-healing wounds but the multi-modal intervention prevents causal attribution. Provides motivation for prospective trials of leech adjunct in diabetic foot ulcers.
