ABSTRACT

We show a systematic review appears to establish if in the cases of gestational thrombocytopenia (GT), it happens greater frequency of births preterm. Material and methods: An electronic search of data bases took place, the level of evidence for each one of reviewed articles was identified and the type of study was classified that represented, to group itself according to its level of intervention. The clinical studies with evaluation of pregnant woman in the third trimester with thrombocytopenia were taken into account, in where the prognosis of the pregnancy with respect to preterm birth (PB), comparing with gestational thrombocytopenia (GT) against immunological thrombocytopenia (ITP). Results: We do not identified clinical studies with level of evidence I or II-1. The prevalence of GT was 6.9% (5.5 to the 8.4%). In children of mother with GT, the prevalence of neonatal thrombocytopenia was 0.80% (0.32-1.46%). Whereas the prevalence of the PB in women with GT, shows a variable behavior of the 5.6, 0.0 and 35.7% for publications of level II-2, II-3 and level III, respectively. The prevalence of births by vaginal via in ITP varies from the 53.0 to 73.1% (average 65.5), whereas for GT was 98.2 to 99.8% (average 99.5). Conclusions: The information available in systematic literature shows an irregular behavior in the report of its results, that is independent of the level of evidence of the evaluated article. This prevents to emit recommendation some for the more common clinical questions related to the TG. Reason why the clinical conduct will have to continue on the base of the consensus reports or personal or institutional experience.
