Maternal and Perinatal Outcomes of Influenza in Pregnancy after Treatment with Oseltamivir.

CONTEXT: Influenza infection in pregnancy causes 4%-8% case fatality and five times more perinatal mortality. Influenza is a major contributor to mortality in developing countries; however, the morbidity has largely been underestimated. Public health interventions for prevention are also lacking. AIMS: This study aimed to determine the seasonality of influenza in pregnant Indian women and to estimate the maternal and perinatal morbidity after treatment with oseltamivir. SETTINGS AND DESIGN: This was a prospective observational cohort study, conducted in a tertiary hospital. SUBJECTS AND METHODS: Pregnant women with ILI (influenza-like illness) were recruited into Cohort 1 (polymerase chain reaction [PCR] positive) and Cohort 2 (PCR negative). Gestational age-matched asymptomatic controls formed Cohort 3. Women in Cohort 1 received oseltamivir for 5 days. The incidence of small-for-gestational age (SGA) and preterm birth were the primary outcomes. Maternal and neonatal morbidity formed the secondary outcomes. STATISTICAL ANALYSIS: Unmatched (Cohort 1 and 2) and matched analysis (Cohort 1 and 3) were done. Student's t-test and Chi-square test were used to compare between variables. RESULTS: Year-round incidence of influenza was recorded. Severe illness was more in Cohort 1 compared to Cohort 2 (36.2% vs. 6.3%; P < 0.001). SGA was comparable in all the cohorts (13%). Preterm birth (7.8% vs. 3.3%; P < 0.08; relative risk-2.75) was considerably high in Cohort 1. Secondary maternal and neonatal outcomes were similar between the groups. CONCLUSION: Influenza in pregnancy showed year-round incidence and increased maternal and neonatal morbidity despite treatment with oseltamivir. We suggest the need for newer interventions to curtail the illness in pregnancy.

Ectopic pregnancies: Catch them early, treat them wisely!

INTRODUCTION: Ectopic pregnancy (EP) is a common condition encountered in Obstetrics and Gynecology. Different management protocols are currently available for haemodymanically stable patients but definitive recommendations is yet to be established, especially in developing countries with limited resources. AIM: To determine the outcome of EP in patients who are haemodynamically stable and to evaluate the factors that would predict success of specific management protocols in them. METHODOLOGY: Haemodynamically stable patients with HCG levels <1500 mIU/ml were recruited for expectant management, 1500-5000 mIU/ml were given MTX and those with >5000 mIU/ml were managed surgically. RESULTS: The overall success rate for expectant management was 92.7% and that with MTX was 80%. Baseline HCG values was found to be the only significant factor for predictor of success of treatment in the expectant group (P 0.05). The size of mass seen on USG did not have a significant correlation with beta HCG values (P 0.257). CONCLUSION: Of all the predictors for success of treatment that have been studied, the initial HCG value alone remains of paramount importance. Women with initial values of HCG <1500 mIU/ml can be offered expectant management, with a much better assurance of success for those with values <1000 mIU/ml. Those with values <5000 mIU/ml can be given MTX, with single dose being sufficient most often for <3000 mIU/ml. The presence of fluid restricted to the pelvis on USG can be managed non-surgically. One should not opt for surgical management only on the basis of size of the adnexal mass on USG.

Evaluating the PGMY-centre hospitalier universitaire vaudois assay as a cost-effective tool for human papillomavirus genotyping in HIV-infected women.

Aims: Cervical cancer is one of the leading causes of cancer among women, worldwide. HIV-positive women tend to have persistent infection and infection with multiple human papillomavirus (HPV) types. There is a need for affordable HPV DNA tests as viable alternatives to the existing costly commercial assays. The aim of the study was to establish PGMY-CHUV reverse hybridization assay as a cost-effective tool for HPV genotyping. Study Design: This was a prospective study conducted in a tertiary care centre from March 2011 to July 2012. Subjects and Methods: Fifty cervical brush samples from HIV-infected women and 43 WHO reference samples were tested by both the CHUV assay and linear array (LA). Results: The CHUV assay in comparison to the LA showed a sensitivity of 91%, specificity of 52% and a moderate agreement for all samples that were compared. However, most high-risk HPV types were identified amongst the clinical samples, and the entire range of genotypes in the WHO reference panel was detected. Statistical Analysis: The accuracy indices such as sensitivity, specificity, positive predictive value and negative predictive value were calculated. The level of agreement (kappa value) between the two assays was also calculated. Conclusion: The CHUV assay had an acceptable sensitivity, but it lacked specificity for HPV detection. Despite the lower rates of detection of multiple infections from clinical samples, better results were obtained with the WHO reference samples and the ability of the assay to identify the entire range of genotypes suggests that it can be an efficient tool for genotyping.

New Evidence to Support Antibiotic Prophylaxis in Meconium-Stained Amniotic Fluid in Low-Risk Women in Labor a Prospective Cohort Study.

PURPOSE OF STUDY: To assess the maternal and perinatal complications associated with meconium-stained amniotic fluid (MSAF) in low-risk women in labor. METHODS: This prospective cohort study was conducted at CMC Hospital, Vellore, India. Two hundred low-risk women who had artificial or spontaneous rupture of membranes after admission with MSAF were included in the study. Two hundred similar women with clear liquor were taken as controls. The primary outcomes considered were the incidence of chorioamnionitis and endomyometritis in the mothers. The secondary outcomes included postpartum hemorrhage and retained placenta in the mothers and respiratory distress, meconium aspiration, sepsis, and NICU admission in the newborn. Statistical analysis was done using Fischer exact test. Odds ratio, 95% confidence interval, and P value were estimated. RESULTS: Compared to controls, those with MSAF had significantly higher rates of chorioamnionitis (2 vs. 8%, P = 0.006) and endomyometritis (3 vs. 9.5% P = 0.007). Among the secondary end points, only neonatal respiratory distress (8.5 vs. 1.5%; P = 0.001) and meconium aspiration (4 vs. 0%; P = 0.007) were found to be significantly increased in the meconium group. CONCLUSION: Statistically significant increased incidence of chorioamnionitis and endomyometritis in women with MSAF in labor established in our study strongly supports the use of prophylactic antibiotics in these women to prevent immediate and long-term consequences.

Comprehensive Maturity Onset Diabetes of the Young (MODY) Gene Screening in Pregnant Women with Diabetes in India.

Pregnant women with diabetes may have underlying beta cell dysfunction due to mutations/rare variants in genes associated with Maturity Onset Diabetes of the Young (MODY). MODY gene screening would reveal those women genetically predisposed and previously unrecognized with a monogenic form of diabetes for further clinical management, family screening and genetic counselling. However, there are minimal data available on MODY gene variants in pregnant women with diabetes from India. In this study, utilizing the Next generation sequencing (NGS) based protocol fifty subjects were screened for variants in a panel of thirteen MODY genes. Of these subjects 18% (9/50) were positive for definite or likely pathogenic or uncertain MODY variants. The majority of these variants was identified in subjects with autosomal dominant family history, of whom five were in women with pre-GDM and four with overt-GDM. The identified variants included one patient with HNF1A Ser3Cys, two PDX1 Glu224Lys, His94Gln, two NEUROD1 Glu59Gln, Phe318Ser, one INS Gly44Arg, one GCK, one ABCC8 Arg620Cys and one BLK Val418Met variants. In addition, three of the seven offspring screened were positive for the identified variant. These identified variants were further confirmed by Sanger sequencing. In conclusion, these findings in pregnant women with diabetes, imply that a proportion of GDM patients with autosomal dominant family history may have MODY. Further NGS based comprehensive studies with larger samples are required to confirm these finding.

Masked hypoglycemia in pregnancy.

BACKGROUND: Hypoglycemia is a major hindrance for optimal glycemic control in women with gestational diabetes mellitus (GDM) on insulin. In the present study, masked hypoglycemia (glucose <2.77mmol/L for ≥30 min) was estimated in pregnant women using a continuous glucose monitoring (CGM) system. METHODS: Twenty pregnant women with GDM on insulin (cases) and 10 age-matched euglycemic pregnant women (controls) between 24 and 36 weeks gestation were recruited. Both groups performed self-monitoring of blood glucose (SMBG) and underwent CGM for 72 h to assess masked hypoglycemia. Masked hypoglycemic episodes were further stratified into two groups based on interstitial glucose (2.28-2.77 and ≤2.22 mmol/L). RESULTS: Masked hypoglycemia was recorded in 35% (7/20) of cases and 40% (4/10) of controls using CGM, with an average of 1.28 and 1.25 episodes per subject, respectively. Time spent at glucose levels between 2.28 and 2.77 mmol/L did not differ between the two groups (mean 114 vs 90 min; P = 0.617), but cases spent a longer time with glucose ≤2.2 mmol/L. Babies born to women with GDM were significantly lighter than those born to controls (2860 vs 3290 g; P = 0.012). There was no significant difference in birth weight within the groups among babies born to women with or without hypoglycemia. CONCLUSION: Euglycemic pregnant women and those with GDM on insulin had masked hypoglycemia. Masked hypoglycemia was not associated with adverse maternal or fetal outcomes. Therefore, low glucose levels in the hypoglycemic range may represent a physiologic adaptation in pregnancy. This response is exaggerated in women with GDM on insulin.

Ultrastructural demonstration of antigen presenting cells in human uterine tube

Langerhans cells (LCs) are the predominant antigen-presenting cells distributed in the mucosa of various organs with high antigenic exposure. They capture antigens, process and present them to the T lymphocytes. LCs are known to be present in the human female reproductive tract. Very few studies have demonstrated the presence of LCs in human uterine tubes. The aim of the present study was to demonstrate the morphology and distribution of LCs in the normal and postpartum human uterine tube by electron microscopy. Tissues from two normal and three postpartum uterine tubes were studied under electron microscopy. The epithelium of the uterine tube varied from simple ciliated columnar epithelium to stratified ciliated columnar epithelium. LCs with a single dendritic process could be identified in the epithelium. The dendritic process displayed the unique Birbeck granules in the cytoplasm. Close apposition of LCs with the intraepithelial lymphocytes was noted. In addition, there were M cells in the epithelium of the normal uterine tube. In the lamina propria, LCs with two or three processes were present which displayed Birbeck granules. They were in close association with lymphocytes as well as with the endothelial cells of the capillaries. A few high endothelial venules (HEVs) were present in the lamina propria of the postpartum uterine tube. The presence of LCs, M cells and HEVs in the uterine tube indicates that the uterine tube is an integral part of mucosa-associated lymphoid tissue

Different subsets of Langerhans cells in human uterine tubes and uterus.

AIM: Langerhans cells (LC) are antigen-presenting cells present in tissues with high antigenic exposure. Their role in the upper female reproductive tract is not fully understood. This study aims to determine the distribution and morphology of LC in the normal and post-partum human uterine tubes and uterus by staining with the specific LC markers, CD1a and zinc iodide-osmium (ZIO), and to determine their association with helper and cytotoxic T cells. MATERIAL AND METHODS: Normal and post-partum uterine tube and uterine specimens were stained with CD1a and ZIO and their morphology and distribution noted. Double immune staining with CD1a-CD4 and CD1a-CD8 in post-partum uterine tube were also done. RESULTS: It was noted that CD1a-positive cells were significantly fewer and smaller in diameter than ZIO-positive cells in the uterine tube and both types of cells were significantly more prevalent in post-partum tubes. Perivascular clusters of ZIO-positive cells were seen in the post-partum tubes. Close association of CD1a-positive cells with CD4- and CD8-positive T cells was noted in the post-partum uterine tube. In the uterus, scanty CD1a-positive cells were present in the surface and glandular epithelium and endometrial stroma. ZIO-positive cells were absent. CONCLUSION: This study suggests that CD1a-positive and ZIO-positive cells may be different subsets of LC that are needed for presentation of antigen to immunocompetent cells. Their respective functions are yet to be determined.

Domestic violence as a risk factor for maternal depression and neonatal outcomes: a hospital-based cohort study.

OBJECTIVES: This study attempted to follow up a cohort of women who presented to a tertiary hospital to investigate the effect of domestic violence on maternal and neonatal outcomes. MATERIALS AND METHODS: Women, between 26-34 weeks of gestation, attending the obstetrics outpatient department, were recruited and followed up until delivery. They were assessed at recruitment and after delivery using the Edinburgh Postnatal Depression Scale, the Abuse Assessment Screen, and a pro forma to assess socio-demographic and clinical characteristics. Bivariate and multivariate statistics were employed to assess statistical significance. RESULTS: One hundred and fifty women were recruited, 132 delivered in the hospital and were followed up. Domestic violence was associated with antenatal and postnatal depression, spouse's insistence of a boy baby, medical complications during pregnancy, preterm delivery, and lower birth-weight. CONCLUSION: Domestic violence has a significant impact on maternal and neonatal outcomes. Screening for domestic violence and interventions should be part of all antenatal programs. India should also employ public health approaches to change its patriarchal culture.

Pandemic (H1N1) 2009 virus infection during pregnancy in South India.

OBJECTIVE: To assess the clinical profile of pregnant/puerperal women from a semi-urban Indian population who were infected with pandemic (H1N1) 2009 virus (P[H1N1]2009v) and to evaluate their outcome. METHODS: In a cross-sectional study, 566 women (79 pregnant/puerperal, 487 nonpregnant) who presented to a tertiary care hospital with influenza-like illness were tested for P(H1N1)2009v by real-time reverse transcriptase polymerase chain reaction. Outcomes measures were the maternal mortality and the perinatal mortality rate (PMR). RESULTS: Twenty (25%) pregnant/puerperal and 144 (30%) nonpregnant women tested positive for P(H1N1)2009v, with 5 pregnant and 3 postpartum women requiring admission to the intensive care unit (ICU). P(H1N1)2009v-related mortality was higher in pregnant than nonpregnant women (25% versus 8%; P=0.04). In the pregnant/puerperal cohort, factors associated with death included delayed presentation (median 6days versus 1.5days in survivors; P=0.007), need for ICU admission (P=0.004), need for ventilation (P=0.001), and renal failure (P=0.001). The PMR was 55.5/1000 births compared with 33.5/1000 births in the hospital overall during the study period. CONCLUSION: In a low-income country, P(H1N1)2009v infection in pregnancy is associated with considerable mortality. Delayed presentation to a tertiary care center, lack of awareness, and restricted access to treatment might have contributed to the high mortality.

HIV-1 seroprevalence and awareness of mother-to-child transmission issues among women seeking antenatal care in Tamil Nadu, India.

BACKGROUND: Despite increasing availability of HIV-1 testing, education, and methods to prevent transmission, Indian women and their children remain at risk of acquiring HIV. We assessed the seroprevalence and awareness about HIV among pregnant women presenting to a private tertiary care hospital in South India. METHODS: Seroprevalence was determined via enzyme-linked immunosorbent assay (ELISA) testing, and questionnaires were analyzed using chi-square statistics and odds ratios to look for factors associated with HIV positivity. RESULTS: A total of 7956 women who presented for antenatal care were interviewed. Fifty-one women of the 7235 women who underwent HIV testing (0.7%) were found to be HIV positive. Awareness of mother-to-child transmission (MTCT) of HIV (64%), HIV transmission through breast milk (42%), and prevention of MTCT (13%) was low. CONCLUSIONS: There is a need to educate South Indian women about HIV to give them information and the means to protect themselves and their unborn children from acquiring HIV.

Amnioinfusion for relief of recurrent severe and moderate variable decelerations in labor.

OBJECTIVE: To determine whether intrapartum amnioinfusion (AI) relieves recurrent moderate and severe variable decelerations in laboring women with clear or grade I meconium-stained amniotic fluid and reduces cesarean section rate for fetal distress. STUDY DESIGN: A randomized controlled trial was conducted in labor unit of Christian Medical College Hospital, Vellore, India, between October 2003 and September 2004. Women were randomized to receive AI (group I) and not to receive it (group II). RESULTS: A total of 150 women (75 in each group) were included in the study. There was significant relief of variable decelerations in group I and no difference in overall cesarean section rate but significant reduction in cesarean section rate for fetal distress in group I, and significant reduction in cesarean section rate for fetal distress in nulliparous women of group I. Neonatal acidemia was also significantly reduced in the nulliparous women receiving AI. The duration of maternal postpartum hospital stay was significantly reduced in group I. There were no adverse maternal or neonatal outcomes. CONCLUSION: AI was a beneficial therapeutic intervention in women patients showing fetal distress in first stage of labor, and it reduced cesarean section for fetal distress and neonatal acidemia.

Prevalence and risk factors for human papillomavirus and cervical intraepithelial neoplasia among HIV-positive women at a tertiary level hospital in India.

OBJECTIVES: The hypothesis to be tested was that the prevalence of human papillomavirus (HPV) and cervical intraepithelial neoplasia would be significantly higher in HIV seropositive women as compared with seronegative controls. Secondary aims were to determine the risk factors for HPV and cervical intraepithelial neoplasia and the HPV types in HIV-positive women. MATERIALS AND METHODS: A cross-sectional study of women 18 to 49 years old was done. Seventy-five women who were HIV seropositive and 58 seronegative women, of whom 27 had HIV-positive partners, participated in the study. A Pap smear and a cervical swab for HPV were done. Women with Pap smear abnormality underwent colposcopy and large loop excision procedures if indicated. RESULTS: Ten (13.3%) HIV-positive women had high-grade squamous intraepithelial lesion as compared with 2 (3.4%) seronegative women (odds ratio [OR] 4.3; 95% CI = 0.9-41.7; p =.048). Among the HIV-positive women, 28 (37.3%) had high-risk HPV, whereas only 9 (15.5%) had high-risk HPV among seronegative women (OR 3.2; 95% CI = 1.3-8.3; p =.009). Among women who were positive for high-risk HPV, the HIV-positive women were significantly more likely to have more than 1 HPV type (OR 7.4; 95% CI = 1.4-43.7; p =.005). Women who had coitus at less than 18 years of age were more likely to have high-risk HPV infection (OR 2.9; 95% CI = 1.2-6.2; p =.013) even after controlling for HIV status. CONCLUSIONS: HIV-positive women have a higher risk for multiple HPV infections as compared with seronegative women. Behavioral factors dominate HIV in determining HPV infections and resultant cervical neoplasia.

HIV and obstetric complications and fetal outcomes in Vellore, India.

Antenatal prevalence is more than 1% in parts of India, yet little is known about the complications and fetal outcomes in this region. We reviewed the records of 23,386 women who delivered at the Christian Medical College Hospital in Vellore, India from 2000 through 2002. HIV-infected women were more likely than HIV-uninfected women to have pregnancy-induced hypertension, anaemia, breech presentations, stillborn babies and fetal deaths. HIV-infected women who did not receive mother-to-child transmission prophylaxis or had breech fetal presentation were more likely to have fetal deaths (P = 0.001). HIV prophylaxis and optimal prenatal care should be a priority for HIV-infected pregnant women in resource-limited countries.

Endometrial resection/vaporization: a patient-friendly first-option treatment for menorrhagia in rural areas.

Hysterectomy, a major surgical procedure, is often an unacceptable procedure for many patients from rural areas who attend small rural hospitals. Near total endometrial resection/vaporization is a more acceptable procedure which can control menorrhagia. This procedure can be carried out with standard urology instruments.
