[Treatment of Raynaud's phenomenon in scleroderma with a new stable prostacyclin derivative].
In a single-blind trial 25 patients with progressive scleroderma and Raynaud's phenomenon intravenous infusions of iloprost, a prostacyclin derivative (carbaprostacyclin), were given daily for five hours during a six-day hospital stay, after a comparable initial single placebo infusion. Duration, frequency and intensity of Raynaud symptoms improved in more than 75% of the patients. This improvement was objectified by telethermometry which demonstrated acral hyperthermia and significantly briefer rewarming after standardized cooling of the hands. In addition, there was more rapid healing of ulcerations and necroses of the digital pulp. A significant inhibition of ADP- and collagen-dependent platelet aggregation was demonstrated during the iloprost infusion. Side effects, such as headache, nausea and tiredness occurred only transitorily during the infusion, were individually highly variable, and then only at higher concentrations. A dosage of 2 ng/kg X min was tolerated by all patients.
