Randomized Controlled Trial Comparative Study Clinical Trial
Use of a low-molecular weight heparin (enoxaparin) or of a phenformin-like substance (moroxydine chloride) in primary early recurrent aborters with an impaired fibrinolytic capacity.
An impaired fibrinolytic capacity, defined as an insufficient venous occlusion-induced shortening of the plasma euglobulin clot lysis time, is a common feature in women suffering from primary early recurrent unexplained miscarriages. We investigated the therapeutic effect of a low-molecular-weight heparin and of a phenformin-like substance. In a prospective, randomized trial, 30 consecutive patients initially received either enoxaparin, 20 mg per day during one month, or moroxydine chloride, 1200 mg per day during one month. ⋯ Concerning the effects on the fibrinolytic system, 20 out of 29 women responded to the first or second-line enoxaparin treatment whereas only 1 woman out of 19 responded to moroxydine chloride (p = 0.00002). Concerning the effects on fertility, responders to LMWH were more likely to initiate a new pregnancy than non-responders (16/20 vs 2/10, p = 0.002). In patients conceiving, LMWH responders were more likely to obtain live births than nonresponders (13/16 vs. 0/2, p = 0.02).(ABSTRACT TRUNCATED AT 250 WORDS)
