INTRODUCTIONAsthma is a common problem around the world with variable prevalence ranging from 1%-18% 1 in different age and geographical distribution. There are proximately 300 million affected individuals in the world. Study by Kwon HL et al suggests that approximately 4.1% of all pregnant women had experienced an asthma attack in previous year.2 Recent study in USA suggests 3.7-8.4% of women had asthma in 1997-2001, as compared to 3.2% according to data in 1988-1994. 3 There are growing prevalence and morbidity, due to asthma associated with pregnancy. Course of asthma in pregnancy is unpredictable, studies suggest that about 1/3rd have exacerbation, 1/3rd improve and rest of 1/3rd show no change in symptoms. 4,5 On the contrary asthma also had adverse effect on fetus and maternal outcomes in pregnant women. Various historical and prospective cohort studies have investigated the effect of maternal asthma on pregnancy outcomes, studies suggest that asthmatic women are more at risk of low birth neonate, preterm delivery, IUGR, congenital deformities and increased hospital stay. Maternal risks includes; preterm labor, preeclampsia, hypertension, antepartum and postpartum hemorrhage, increased cesarean section and forceps delivery. There are fewer studies on asthma & its ABSTRACTBackground: Asthma is a common problem all around the world with variable prevalence ranging from 1%-18% in different age and geographical distribution. There are proximately 300 million affected individuals. There are growing prevalence and morbidity, due to asthma associated with pregnancy. The course of asthma in pregnancy is unpredictable. Methods: 2400 consecutive pregnant women attending the antenatal clinic of S.P. Medical College and AG of Hospitals, Bikaner, were screened using asthma questionnaire translated in Hindi based on the questionnaire developed for International Union against Tuberculosis and Lung Disease. 52 patients diagnosed as asthma were subjected for PFT and classified according to clinical severity as per GINA guidelines, 2006. All subjects were followed till delivery and postpartum charts reviewed to see neonate and maternal outcome. Results: The prevalence of asthma during pregnancy was 2.1%, among them, 25 (48.1%) were categorized as having intermittent asthma, 6 (11.5%) with mild persistent asthma, 10 (19.2%) with moderate persistent asthma and 11 (21.2%) having severe persistent asthma. During the course of pregnancy, 36% had no change in the symptomatology, while (32.5%) experienced improvement and (32.5%) of worsening of asthma. 22 (42.31%) women were newly diagnosed during our study. There was no significant adverse maternal and fetal outcome in asthmatic group compared to control. Conclusions: Asthma is an under diagnosed and under treated disorder, especially during pregnancy and overall morbidity of asthma among women & neonates does not change during pregnancy.

“…Asthma is known as one of the most frequent chronic diseases encountered during pregnancy, affecting up to 8.8% of pregnant women [1]. Adverse perinatal outcomes, such as a preterm birth, a low-birth-weight (LBW) infant and a small-for-gestational-age (SGA) infant, have been reported to be higher in pregnant women with asthma when compared to women without asthma in some studies [2][3][4][5][6][7][8][9][10], but not in other studies [11][12][13][14][15][16][17][18].…”

There are conflicting results concerning the impact of maternal asthma during pregnancy on perinatal outcomes. The present study investigated the associations between maternal asthma during pregnancy and the risk of a small-for-gestational-age (SGA) infant, a low-birth-weight (LBW) infant, and preterm birth. A population-based cohort of 40,788 pregnancies from asthmatic and non-asthmatic women was reconstructed through the linking of three Quebec (Canada) administrative databases between 1990 and 2002. A two-stage sampling cohort design was used to collect additional information by way of a mailed questionnaire. The generalized estimation equation models were used to obtain adjusted odds ratios of SGA, LBW and preterm birth comparing asthmatic and non-asthmatic women. The cohort included 13,007 pregnancies from asthmatic and 27,781 pregnancies from non-asthmatic women. Final estimates showed that the odds of SGA (odds ratio: 1.27, 95% confidence interval: 1.14, 1.41), LBW (1.41: 1.22, 1.63) and preterm delivery (1.64: 1.46, 1.83) were significantly higher among asthmatic than non-asthmatic women. Mothers with asthma during pregnancy are more likely to have SGA, LBW, or preterm birth infants than non-asthmatic women. These results can be more easily generalized to women with lower socio-economic status since the cohort under represents women with high socio-economic status.

“…Die hö-here Prävalenz von Asthma bei (allen) Frauen im Alter von 18-24 Jahren im Vergleich zu 25-bis 34-Jährigen bzw. 35-bis 44-Jährigen spricht dafür, dass die Anzahl von Frauen, die während der Schwangerschaft an Asthma leiden, weiter zunimmt [18]. Die vorliegenden Prävalenzanga-ben für Asthma während der Schwangerschaft in Europa sind variabel (~3,8-6,6%).…”

Ein bekannter Risikofaktor für die Entstehung von Asthma sind betroffene Verwandte ersten Grades, wobei mütterliches Asthma einen hö-heren Risikofaktor darstellt als väter-liches Asthma. Weiter ist belegt, dass allergische Sensibilisierung bereits in utero erfolgen kann. Diese Beobachtungen legen nahe, dass pränatal wirksame Mechanismen, wie epigenetische Modifizierungen, eine Rolle bezüglich des Asthmarisikos spielen.
