Prevalence of diseases screened by a pregnancy protection program of the State of Mato Grosso do Sul, Brazil, 2004 -2007

Abstract

The reduction of infantile and maternal morbi-mortality should be treated by the
services of public health as a primordial goal. The State of Mato Grosso do Sul
implanted a differentiated program of diagnosis and follow-up of some diseases. The
results of a transversal study involving 153,857 pregnant women who were attended
by the Pregnancy Protection Program of the state of Mato Grosso do Sul between
2004 and 2007 are presented here. This study objectified to evaluate the prevalence
of the screened diseases, to calculate the predictive value of these tests as well as
to identify differences of prevalence in the age groups. The prevalence found for
the tests were: toxoplasmosis: 12.79, rubella: 1.75, cytomegalovirus: 1.03, simplex
herpes virus: 0.5, syphilis: 26.91, HIV 1 and 2: 2.28, Chagas disease: 3.33, hepatitis
B (HBsAg): 3.04 hepatitis C: 1.59, maternal phenylketonuria: 0.02, HTLV I and
II (Human T-cell lymphotropic virus): 2.03, Chlamydia: 73.97, hypothyroidism:
0.8. Differences in the prevalence among age groups and infections by rubella,
cytomegalovirus, Chagas disease and simplex herpes virus were observed. The prevalence rates obtained were near those already described in the literature for
Brazil. The Positive predictive value of the test used in relation to the confirmation
was high, highlighting the methodology of screening by the method of the dry
blood in paper filter. The continuity of the prenatal screening and the follow-up of
the child after the birth are measures that certainly will reduce the prevalence and
complications of the diseases screened, throughout the time.
