Scientific titleA single-centre randomised controlled trial of Antibiotic Prophylaxis before second-trimester Genetic Amniocentesis in women: the APGA trial
Study acronymAPGA Trial
Study objectivesWe hypothesise that:
1. There exists a risk factor for infection that could be responsible for rupture of the membranes (preterm Premature Rupture Of Membranes [pPROM]) and often for foetal death, and that this risk factor is present even before the amniocentesis procedure is undertaken
2. Antibiotic prophylaxis before amniocentesis can prevent pPROM and/or foetal death
Ethics approval(s)Ethics approval obtained from the Local Ethics Committee of the "Artemisia Medical Institute Network" (created according to the guidelines reported in the "Decreto Ministeriale (DM) 15/7/1997", Ministry of Health of Italy) on the 12th September 1998.
Health condition(s) or problem(s) studiedPreterm Premature Rupture Of Membranes (pPROM), foetal death
InterventionIntervention:
Oral azithromycin 500 mg daily for the three days prior to the amniocentesis procedure, in three doses taken at 24-hour intervals.

Control:
No therapy.

Both groups have a scan on the day of the amniocentesis. The women have to be discharged 30 minutes after completion of the procedure. The patients that present any complications, within 4 weeks, must to be checked into the Centre with a scan and PROM test. The coordinators, after 4 weeks, will check by phone that all women will not come back to the centre for prescribed control. All study personnel were blinded to treatment assignment for the duration of the study.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Azithromycin
Primary outcome measureTo determine the efficacy of antibiotic prophylaxis in second-trimester amniocentesis in preventing the foetal death in both groups, assessed four weeks after the procedure.
Secondary outcome measures1. To determine the incidence of pPROM in both groups, defined as a rupture of the membranes, assessed four weeks after the procedure
2. To evaluate the incidence of foetal death after the pPROM in both groups, assessed four weeks after the procedure
Overall study start date02/01/1999
