RESUMEN
Infertility is defined as 1 year of unprotected sexual intercourse without pregnancy. It is further classified as primary and secondary. Secondary infertility is one in which prior pregnancy not necessarily live birth has occurred. Pelvic infections as a cause for infertility are seen in 12% cases while genital tuberculosis contribute 10-15%. Various studies have well established a relationship between subclinical infection and infertility with the two most potential pathogens being: Chlamydia trachomatis and mycoplasma species. Authors are presenting two cases one of a 30yr female, P0+5, with class 2 obesity with previous three ectopic pregnancies with LSO done 1 year back i/v/o left ruptured ectopic now presenting with secondary infertility for 1 year and another case of a 21 years female, P0+2, with previous two ectopic with LSO done 2 years back now presenting with infertility. These cases emphasize that infections are important causes for recurrent ectopic pregnancies and infertility.
RESUMEN
OBJECTIVE: Adenosine deaminase acts on adenosine and deoxyadenosine metabolism and modulates the immune response. The adenosine deaminase G22A polymorphism (20q.11.33) influences the level of adenosine deaminase enzyme expression, which seems to play a key role in maintaining pregnancy. The adenosine deaminase 2 phenotype has been associated with a protective effect against recurrent spontaneous abortions in European Caucasian women. The aim of this study was to investigate whether the G22A polymorphism of the adenosine deaminase gene is associated with recurrent spontaneous abortions in Brazilian women. METHODS: A total of 311 women were recruited to form two groups: G1, with a history of recurrent spontaneous abortions (N = 129), and G2, without a history of abortions (N = 182). Genomic DNA was extracted from peripheral blood with a commercial kit and PCR-RFLP analysis was used to identify the G22A genetic polymorphism. Fisher's exact test and odds ratio values were used to compare the proportions of adenosine deaminase genotypes and alleles between women with and without a history of recurrent spontaneous abortion (p<0.05). The differences between mean values for categorical data were calculated using unpaired t tests. The Hardy-Weinberg equilibrium was assessed with a chi-square test. RESULTS: Statistically significant differences were identified for the frequencies of adenosine deaminase genotypes and alleles between the G1 and G2 groups when adjusted for maternal age. CONCLUSIONS:The results suggest that the adenosine deaminase *2 allele is associated with a low risk for recurrent spontaneous abortions, but this association is dependent on older age.
