A large Italian observational multicentre study on vascular ulcers of the lower limbs (Studio Ulcere Vascolari).

An observational study of 2 years was promoted by the Italian Association for Cutaneous Ulcers (AIUC) in order to monitor the epidemiology of leg ulcers, the trend of healing and the more frequent therapeutic approaches in lower limb ulcers. Fifty-nine sites in 14 different Italian regions involved in the study, with 1333 enrolled patients (1163 patients fully evaluated and followed up for 9 months). A prevalence of females (62%) was observed with a mean age of 70 years and a high rate of hypertension (62%), diabetes (38%) and obesity (29%). Venous ulcer was most frequent (55%), followed by mixed (25%) and diabetic (8·3%) ulcers. Basically, all patients received a local therapy (LT) (compression and advanced local therapies), while 63% of patients have an associated systemic pharmaceutical treatment. Ulcer healing rates progressively increased throughout the study and despite the type of observational study does not allow conclusions on the treatment, it was observed that the patients receiving additional systemic drugs were associated with a more rapid acceleration of healing rates of ulcers compared to LT alone (3 months: 39·7% versus 29·2%; 6 months: 62·0% versus 47·0%; 9 months: 74·7% versus 63·8%). In particular, the Studio Ulcere Vascolari (SUV) study showed that a combination treatment with sulodexide and compression therapy allows for a greater increase in the healing rates in venous ulcers.

Effects of iloprost on pain-free walking distance and clinical outcome in patients with severe stage IIb peripheral arterial disease: the FADOI 2bPILOT Study.

BACKGROUND: Patients with peripheral arterial disease (PAD) at stage IIb, pain-free walking distance (PFWD) less than 100 m and unsuitable for revascularization have both impaired quality of life and severe clinical outcome. Aim of the study was to evaluate the efficacy of the prostacyclin analogue iloprost, added to standard therapy, in these patients. MATERIAL AND METHODS: Patients were randomized to receive standard medical therapy (Group A) or standard therapy plus iloprost (Group B), for 1 year. Iloprost was administered for 10 days every 3 months. Treadmill test was performed every 3 months, in Group B before starting the 10-day iloprost cycle. RESULTS: Fifty patients in Group A and 51 in Group B were enrolled. Mean baseline and 12-month PFWD values were 75.4 ± 21.3 and 128.9 ± 62.9 for iloprost group and 70.3 ± 21.6 and 99.6 ± 62.6 m for controls. Patients treated with iloprost had significantly higher PFWD at 9 and 12 months. This finding was confirmed after carrying forward the last valid observation (124.7 ± 63.4 vs. 88.4 ± 63.1 m, P < 0.01). Major cardiovascular events occurred in 32.0% and 3.9% of patients in Group A and Group B, respectively (P < 0.001). Five patients in Group A died vs. none in Group B (P = 0.02). No serious unexpected adverse reactions occurred in patients receiving iloprost. CONCLUSIONS: Iloprost, added to standard therapy, significantly increases exercise capacity in patients with PAD at severe stage IIb. The percentage of patients who died or experienced major cardiovascular events was significantly lower in patients receiving iloprost. Future studies should focus on the effects of this therapy on clinical outcome.
