Dehydrated Amniotic Membrane Allograft for Treatment of Chronic Leg Ulcers in Patients With Multiple Comorbidities: A Case Series.

Cellular and/or tissue-based products (CTPs) are emerging treatment options for chronic non-healing wounds. Dehydrated amniotic membrane allograft (DAMA) was used in 7 patients whose wounds had not responded adequately to standard and adjuvant therapies; four VLUs, 2 surgical wounds, and 1 DFU. Patients had multiple comorbidities, including 2 with autoimmune disorders (CREST syndrome and systemic lupus erythematosus). Patients received 3-8 applications of DAMA at weekly to biweekly intervals (average, 5.4 applications). Complete wound healing was observed in 6 of 7 patients during study period, with an average time to closure of 7.9 weeks. Closure was achieved in 3 of 7 patients after 3 DAMA applications. In the patient with CREST syndrome who did not completely close, DAMA reduced the area and volume by nearly 50% and later went on to closure. These cases suggest that DAMA is a viable option for recalcitrant DFUs, VLUs, and surgical wounds.
