ABSTRACT

OBJECTIVES: To determine the occurrence of MTHFR gene polymorphisms and to study their association with vitamin B12 deficiency and adverse perinatal outcomes among a cohort of pregnant women from Kaniyambadi block, Tamil Nadu. METHODS: 120 consecutive pregnant women who were ≤20 weeks of gestational age from the 82 villages of Kaniyambadi block were recruited. Genomic DNA was isolated from the peripheral blood. PCR amplification was done followed by Sangers sequencing. Maternal and neonatal outcomes were extracted. Data was entered and analysed. RESULTS: Our study found the occurrence of c.1298A>C variant in homozygous state in 14.2% and c.677C>T heterozygous state in 15%. Sanger sequencing of exon 7 identified another pathogenic variant c.1262G>T in heterozygous state in two of them. Both the mothers who harboured that variant had preterm delivery and one of them gave birth to a low-birth-weight neonate. In the entire cohort, 5% of the mothers had abortion, 4.2% of them had preterm delivery and 8.8% of the neonates had low birth weight. Presence of c.1298A>C or c.677C>T variants were associated with vitamin B12 deficiency [Pearson Chi squared value (χ2)=7.9 and 7.6 respectively; p=0.02]. Heterozygous pathogenic variant c.1262G>T was associated with both adverse maternal [χ2=11.5; p=0.001] and neonatal [χ2=18.3; p=0.009] outcomes. CONCLUSIONS: MTHFR gene polymorphisms could be associated with several adverse perinatal outcomes and vitamin B12 deficiency. Further larger studies are needed to prove the pathogenicity of c.1262G>T variant on pregnancy.

ABSTRACT

Background: Hypertension is one of the most common medical disorders complicating pregnancy. In India, high blood pressure contributes to 7.1% of maternal deaths. This study was carried out to describe the characteristics and pregnancy outcomes of patients presenting with eclampsia or pre-eclampsia to a secondary care hospital in rural India. Methods: Patients diagnosed with pre-eclampsia or eclampsia between January 2018 and April 2021 were identified and included in the study. Medical records were searched and general patient characteristics, obstetrical history, information about the antenatal period, mode of delivery and outcomes were documented and analysed. Results: Among the 3651 women who delivered in this hospital during this time period, 2.3% (n = 83) presented with eclampsia and 1.9% (n = 71) with pre-eclampsia. More than 50% of the women delivered by lower segment caesarean section among both the eclamptics and pre-eclamptics. The stillbirth rate among those with either pre-eclampsia or eclampsia was 1 per 1000. The number of low birth weight babies born to those presenting with eclampsia (66.7%) was significantly more than those presenting with pre-eclampsia (48.6%). Eclampsia/pre-eclampsia accounted for 21% of all maternal deaths with a case fatality rate of 2.6%. Conclusions: This study identified that in this setting the patients presenting with eclampsia were much higher than those presenting with pre-eclampsia which is in stark contrast to the status even in developing countries. This could be an important finding indicating poorer health-seeking behaviour among the population and will need more studies on various interventions to change this status.

ABSTRACT

BACKGROUND: Hypertensive disorders in pregnancy are one of the common causes for perinatal and maternal morbidity and mortality in developing countries. Pre-eclampsia is a condition which typically occurs after 20 weeks of gestation and has high blood pressure as the main contributing factor. The aim was to study the effects of pre-eclampsia on the mother and the fetus in rural South Indian population. MATERIALS AND METHODS: This was a descriptive study conducted in a secondary level hospital in rural South India. A total of 1900 antenatal women were screened for pre-eclampsia during the period August 2010 to July 2011 to study the effects on the mother and fetus. RESULTS: Of the 1900 women screened 93 were detected with pre-eclampsia in the study. Among these, 46.23% were primigravida, 30.1% belonged to socio-economic class 4 and 48.8% were among those with BMI 26-30. The incidence of severe pre-eclampsia was higher in the unregistered women. The most common maternal complication was antepartum hemorrhage (13.9%) and the most common neonatal complication was prematurity (23.65%). CONCLUSIONS: Treating anemia and improving socioeconomic status will improve maternal and neonatal outcome in pre-eclampsia. Antenatal care and educating women on significance of symptoms will markedly improve perinatal morbidity and mortality. Prematurity, growth restriction and low birth weight are neonatal complications to be anticipated and dealt with when the mother has pre-eclampsia. A good neonatal intensive care unit will help improve neonatal outcomes.
