the measurment of various cytokines may provide a different tool for evaluation of the immune system. recent investigations have shown that the number and function of peripheral natural killer cells (nk- cells) increase during early pregnancy in women with a history of unexplained recurrent spontaneous abortions (rsa). nk-cells activity may be responsible for some cases of rsa. the objective of...

The etiology of recurrent spontaneous abortion (RSA) is still unexplained. Many couples do not find the cause of their RSA at all. The purpose of this research was to evaluate the association between recurrent pregnancy loss and previous (cured prior to pregnancy) acute/chronic genitourinary infections in both parents.

We evaluated the folate and cobalamin status in 29 non-pregnant women with a history of recurrent spontaneous abortion (three or more consecutive) of unknown aetiology in comparison to 29 healthy nulligravidae of similar reproductive age (controls). Serum concentrations of folate and cobalamin showed no significant differences between the two groups. No correlation between age and vitamin conce...
