[Efficacy and safety of collagen biomaterial local application in complex treatment of the diabetic foot syndrome (final results of the multicenter randomised study)]. / Éffektivnost' i bezopasnost' mestnogo primeneniia kollagenovogo biomateriala v kompleksnom lechenii sindroma diabeticheskoi stopy (itogi mnogotsentrovogo randomizirovannogo klinicheskogo issledovaniia).

AIM: To evaluate the efficacy and safety of collagen biomaterial application during the 4-week follow-up of patients with diabetic foot syndrome. MATERIAL AND METHODS: 75 patients with diabetic foot (Wagner II (69.3%) and III (30.7%)) aged 30-80 years were included in the multicenter study, among them were 50.7% with the wound unhealed for 1.5-6 months and 49.3% over 6-48 months. Patients were randomized into 2 groups: 1) standard therapy (n=37), 2) the additional use of the collagen material Collost (n=38). Observation period was at least 4 weeks for each patient. The size of ulcers, results of general and biochemical blood tests, oximetry, microbiological testing, ultrasound of lower extremities vessels as well as a detailed medical history, social and functional status, level of cardiovascular comorbidity and ongoing therapy were estimated. RESULTS: Additional use of a collagen biomaterial has led to a significant reduction ulcers of all sizes from 13.5 to 2.1 cm2 (in the comparison group - from 12.5 to 7 cm2). The best dynamics have been registered in Wagner II (4.4-fold average wound area regress in Collost group, from 8.8 to 2.0 cm2; average wound area regress by 1.8 times, from 10 to 5.6 cm2 in the comparison group) than in Wagner III group (in the main group from 55 to 21.3 cm2; in the control group from 36 to 32.4 cm2) and in ulcers existing less than 6 months. Treatment with biological material Collost within standard therapy after 4 weeks led to increase of complete epithelialization by 2.6% (21.1% as compared to 14.7%), while decreasing the frequency of ineffective treatment by 4.1 (7.9% in primary and 32.4% in the comparison group). CONCLUSION: We have proved the efficacy and safety of collagen biomaterial topical application in a diabetic foot syndrome treatment.

[The first experience of using a single-layer intra-abdominal collagen plate].

UNLABELLED: The aim of this study was to define the possibility of using a collagen substance CollGARA as a protective barrier between the polypropylene mesh implant and abdominal organs. The drug is a sterile bioabsorbable membrane consisting of refolded equine collagen. Indications--use as barrier separating adjoining tissues and organs in the areas of the abdominal cavity, where the formation of adhesions. MATERIALS AND METHODS: Were performed 10 operations in patients with ventral hernias with different localization. 8 patients had postoperative hernia in 2--linea alba hernia. 8 patients were operated open, 2--laparoscopically. After intra-abdominal hernia repair was performed plastic mesh implant, delimiting it from the abdominal cavity membrane CollGARA. Serious complications from the abdominal cavity and the surgical wound wasnt observed. RESULTS: The first experience with intra-abdominal plastic polypropylene mesh implant coated with collagen plate indicates the possibility of applying this method in the future.
