Intensified case finding for screening tuberculosis among antenatal women in Delhi, India; A facility-based prospective observational study

The clinical presentation and detection of tuberculosis during pregnancy and in the postpartum period in low- and middle-income countries: A systematic review and meta-analysis

For women infected with Mycobacterium tuberculosis, pregnancy is associated with an increased risk of developing or worsening TB disease. TB in pregnancy increases the risk of adverse maternal and neonatal outcomes, however the detection of TB in pregnancy is challenging. We aimed to identify and summarise the findings of studies regarding the clinical presentation and diagnosis of TB during pregnancy and the postpartum period (within 6 months of birth) in low-and middle-income countries (LMICs). A systematic review was conducted searching Ovid MEDLINE, Embase, CINAHL and Global Index Medicus databases. We included any primary research study of women diagnosed with TB during pregnancy or the postpartum period in LMICs that described the clinical presentation or method of diagnosis. Meta-analysis was used to determine pooled prevalence of TB clinical features and health outcomes, as well as detection method yield. Eighty-seven studies of 2,965 women from 27 countries were included. 70.4% of women were from South Africa or India and 44.7% were known to be HIV positive. For 1,833 women where TB type was reported, pulmonary TB was most common (79.6%). Most studies did not report the prevalence of presenting clinical features. Where reported, the most common were sputum production (73%) and cough (68%). Having a recent TB contact was found in 45% of women. Only six studies screened for TB using diagnostic testing for asymptomatic antenatal women and included mainly HIV-positive women ‒ 58% of women with bacteriologically confirmed TB did not report symptoms and only two were in HIV-negative women. Chest X-ray had the highest screening yield; 60% abnormal results of 3036 women tested. Screening pregnant women for TB-related symptoms and risk factors is important but detection yields are limited. Chest radiography and bacteriological detection methods can improve this, but procedures for optimal utilisation remain uncertain in this at-risk population.

An extremely rare case of endophthalmitis in an infant with congenital tuberculosis

Congenital tuberculosis (CTB) is the transmission of Mycobacterium tuberculosis infection from mother to infant during the intrauterine period or delivery. An 82-day-old infant presented to Nilratan Sircar Medical College and Hospital, Kolkata, with a history of persistent fever from Day 15 of age. Over the course of more than 2 months, there were pneumonia, hepatosplenomegaly and endophthalmitis which were unresponsive to a range of antibiotics, and there had been several admissions to local hospitals. On this admission, his chest radiograph and contrast-enhanced computed tomography (CECT) of the thorax demonstrated bilateral nodules and enlarged mediastinal lymph nodes. Ultrasound and CECT of the abdomen demonstrated hepatosplenomegaly with multiple hypodense enhancing lesions. GeneXpert of a gastric lavage on Day 2 of this admission detected M. tuberculosis without rifampicin resistance. The infant was diagnosed with tuberculosis (TB) complicated by caseating hepatic granulomas, which fulfilled Cantwell's diagnostic criteria for CTB. Magnetic resonance imaging of the orbit demonstrated focal heterogeneous lesions involving the anterior portion of the left ocular bulb and vitreous, suggesting panophthalmitis, which was unresponsive to intravitreal antibiotics. Following commencement of standard anti-TB therapy from Day 90 of life, there was clinical and radiological recovery of endophthalmitis. The mother had a cachectic appearance owing to weight loss, and she had attended only one antenatal appointment. She had a positive acid-fast bacilli sputum stain but was unwilling to allow a genital tract smear. In the spectrum of CTB, TB panophthalmitis is an extremely rare presentation, and, as far as we are aware, it has not been reported in a child.Abbreviations: AFB: acid-fast bacilli; ATT: anti-tuberculous therapy; CTB: congenital tuberculosis; CECT: contrast-enhanced computed tomography; CSF: cerebrospinal fluid; ESR: erythrocyte sedimentation rate; HIV: human immunodeficiency virus; TB: tuberculosis; MRI: magnetic resonance imaging; USG: ultrasonogram.
