Abstract

Objective: Rubella and toxoplasma infections are considered as causes of congenital anomalies. The aim of this study was to evaluate the incidence of rubella and toxoplasma infections in pregnancy and determine risk factors which related with infection. Material and Method: This retrospective study was conducted in January 2014- December 2014. In this study, the screening of rubella and toxoplasma test results of 2947 pregnant women with unknown pre-pregnancy serological status were evaluated. The women who were screened for rubella and toxoplasma with immunoglobulin (Ig) G and IgM antibodies in first trimester of present pregnancy included. The screening protocol was standardized. Both IgG and IgM antibodies for screening rubella and toxoplasma were evaluated. Results: Presence of IgM antibody positivity alone was not detected in any women. High avidity was detected in 52 out of 55 women who were IgM antibody positive, which excluded primary infection. Two women were positive for rubella IgG and IgM antibodies with low avidity index were considered have acute infection. In one woman with IgG and IgM antibodies positive against Toxoplasma gondii, avidity index was borderline and susceptible to acute infection during pregnancy. High abortion rates were revealed in women who diagnosed with toxoplasma seropositivity. Discussion: Assessment of IgG and IgM antibodies followed by IgG avidity testing for inconclusive results represents an acceptable approach in pregnant women with unknown pre-pregnancy serological status.

Özet

Amaç: Rubella ve toxoplazma enfeksiyonları konjenital anomalilerin başlıca sebepleri arasında yer almaktadır. Bu çalışmanın amacı gebelikte rubella ve toxoplazma gondii enfeksiyon oranın değerlendirilmesi ve enfeksiyonlar ile ilişkili risk faktörlerinin tespitidir.Gereç ve Yöntem: Bu retrospektif çalışmada Ocak 2014 – Aralık 2014 arasında önceden rubella ve toxoplazma açısından serolojik durumu bilinmeyen 2947 gebenin sonuçları değerlendirildi. Hastaların çalışmaya dahil edilme kriteri olarak gebeliğin ilk trimesterinde rubella ve toxoplazma enfeksiyon taraması için IgG ve IgM antikorları ile değerlendirilmiş olması alındı. Taranma için standart bir protokol kullanıldı. Bu protokolde gebelerden alınan serum örneklerinde rubella ve toxoplazma antijenine karşı IgG ve IgM antikor seviyeleri ölçüldü. Bulgular: Çalışmaya dahil edilen hastaların hiçbirinde tek başına IgM antikor pozitifliğine rastlanmadı. IgM antikoru artmış olan 55 gebenin yapılan avidite değerlendirmesinde 52’sinde yüksek avidite tespit edildi ve akut enfeksiyon dışlandı. Bununla birlikte rubella IgG ve IgM antikoru yüksek tespit edilen 2 gebede avidite sonucunun düşük olduğu ve toxoplazma IgG ve IgM antikoru yüksek tespit edilen 1 gebenin avidite sonucu sınırda düşük olduğu ve akut enfeksiyon ihtimali tespit edildi. Gebelik sonuçları açısından değerlendirildiğinde ise toxoplazma seropozitivitesi olan hastalarda abortus oranın yüksek olduğu tespit edildi. Sonuç: Gebelik öncesi serolojik durumu bilinmeyen hastalarda akut rubella ve toxoplasma gondii enfeksiyonlarının tespiti için enfeksiyon ajanlarına karşı IgG ve IgM antikorlarının değerlendirilmesi ve şüpheli sonuçlar varlığımda IgG avidite testinin yapılması kabul edilebilir bir yaklaşımdır.
