Prevalência de toxoplasmose em gestantes triadas pelo programa estadual de proteção a gestantes de Mato Grosso do Sul, no período de 2011

Abstract

Toxoplasmosis is a zoonosis of broad geographic distribution, caused by intracellular protozoan Toxoplasma gondii. The transmission of toxoplasmosis to humans usually occurs by ingestion of cysts, oocysts in contaminated food, blood transfusion, organ transplantation or form the placenta, which can cause serious consequences to the fetus, so a disease of public health importance. Toxoplasmosis has diagnosis based on the detection of anti-T. gondii. This study aimed to identify the seroprevalence of anti-T.gondii IgM / IgG in pregnant women screened by the State Program to Protect Pregnant Women in Mato Grosso do Sul relationship with its regional distribution and age of the patients. We conducted a descriptive study, quantitative and retrospective study, which consisted of pregnant women screened in every state of Mato Grosso do Sul, in the period January to December 2011. The results showed that within 38 849 a number of pregnant women screened, yielding a frequency of 0.502% for seropositivity acute T. gondii. It was observed that 93.6% of pregnant women had reactive IgG and IgM serology is negative, showing previous exposure to infection, and 5.9% had IgG and IgM serology reagents, revealing susceptible to acquiring the infection. Among the population with acute seropositivity group 1 - toxoplasmosis confirmed in the two tests that accounted for 92% of pregnant women. Group 2 - toxoplasmosis confirmed only in the first phase of tests that accounted 88% women. Group 3 - toxoplasmosis confirmed only in the second phase of tests that accounted for 15% of pregnant women. The age group with the highest seroprevalence was 20 to 24 years. Among the meso southwest was the one with a higher percentage of confirmed cases (40.53%). As the Microregions, Campo Grande had the highest percentage (28.71%) followed closely by Microregion of Gold (27.72%). The results show that the prevalence of toxoplasmosis in pregnant women is relatively high, reaffirming the importance of early diagnosis in pregnant women providing adequate treatment.
