Subclinical hypothyroidism among infertile women at a tertiary hospital in South-West Nigeria.

Background: Overt thyroid dysfunction is an accepted cause of female infertility. Its milder form, subclinical hypothyroidism have also been implicated as a contributing factor to disturbed reproductive function. Objective: To determine the contribution of subclinical hypothyroidism (SCH) to the burden of infertility. Methodology: This is a cross sectional, comparative study of One hundred and twenty women with primary or secondaryinfertility who presented for evaluation at gynaecological clinic and controls which are clients that came to access Family planning services. Results: The prevalence of infertility among gynaecological patients seen in the clinic was 38.8% (192/495). The prevalence of SCH among the studied infertile women was 11.7% (7/60) compared with 3.3% (2/60) of the control group (p=0.222). The commonest type of infertility was secondary, 76.7% (46/60). All thestudied infertile women with SCH presented with secondary infertility. There was an observed statistically significant difference in the mean serum TSH (3.19±4.38mIU /L vs 1.60±1.22mIU /L) and FT3, FT4 (0.29±0.074ng/dl vs 0.95±0.16ng/dl and 0.33±0.071ng/dl vs 1.09±0.19ng/dl respectively). Conclusion: Subclinical hypothyroidism was found to be higher among infertile women but this finding was not statistically significant, therefore, the routine screening for SCH among infertile women might be unnecessary.

Bacterial vaginosis in pregnancy and early labour using Nugent scoring and the implication on foetal outcome.

BACKGROUND: To compare the pattern of vaginal microflora during pregnancy with pattern in early labour using Nugent scoring and determine the effect of these changes on fetal outcome. DESIGN: A prospective longitudinal study. SETTING AND POPULATION: Pregnant women attending antenatal clinics of Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria between June 2017 and May 2018. METHODS: Consenting pregnant women who attended antenatal clinics were recruited. Vaginal secretions were obtained for Nugent scoring during pregnancy and at presentation in labour. MAIN OUTCOME MEASURES: Prevalence of abnormal vaginal flora in pregnancy and early labour, birth outcome, birth weight, gestational age at delivery, APGAR scores, need for neonatal ward admission. RESULTS: Sixty-seven (33.3%) of pregnant women had abnormal flora which was consistent with bacterial vaginosis. At the presentation of these women in labour, 14.4% of them had bacterial vaginosis thus indicating a significant reduction in abnormal vaginal flora in labour compared to the proportion of abnormal flora in antenatal period (P<0.001). There were no significant differences in the fetal outcomes of mothers with bacterial vaginosis when compared with those with normal vaginal flora (P-value >0.05). CONCLUSIONS: Persistence of abnormal vaginal microflora from pregnancy till early labour did not seem to be associated with poorer foetal outcomes when compared with women with normal vaginal microflora in labour. The possibility of persistent infection or re-infection before labour may justify the need for re-evaluation of vaginal smears in the late third trimester to allow for prompt treatment before the onset of labour. FUNDING: This research work was sponsored by the Tertiary Education Trust Fund, Nigeria (TETFund) with reference number OOU/IBR/010.

Vaginal Candida infection in pregnancy and its implications for fetal well-being.

Vaginal Candida infection is one of the most common genital tract infections reported in pregnant women. This study was designed to determine the prevalence of vaginal Candida infection and pattern of Candida species isolates in the genital tract of pregnant women during antenatal period and in early labour; and the associated fetal outcome. The study was conducted at the antenatal clinic and labor ward of Olabisi Onabanjo University Teaching Hospital Sagamu, Ogun State, Nigeria. High vaginal swabs were collected from 408 pregnant women at the antenatal clinic and repeated in early labour. The samples were processed to isolate Candida species. Data were analysed using Statistical Package for Social Science (SPSS) windows version 21.0 (IBM Corp., Armonk, NY, USA). Prevalence of Candida infection was significantly higher in early labour (46%) than during antenatal period (38%) (P=0.02). Candida albicans was the predominant isolate, followed by Candida glabrata and Candida tropicalis. Candida infection was associated with increased likelihood of low birth weight babies (AOR 2.8, CI: 1.1-6.8; P= 0.03). However there was no statistically significant effect of Candida infection on the likelihood of preterm delivery (AOR 1.4, CI: 0.7-2.6; P= 0.35). Routine screening and prompt treatment of women at risk of delivering low birth weight babies is advocated.
