Congenital Tuberculosis in a Neonate: A Diagnostic Dilemma

Disseminated Congenital Tuberculosis in Neonates: A Case Series

Congenital tuberculosis (CTB) is an uncommon yet, well-defined condition. CTB has a non-specific clinical presentation, making the diagnosis difficult. The rarity of CTB in neonates is due to the difficulty in distinguishing between congenital and postnatally acquired infection, and non-specific symptoms in the newborn, which are often misdiagnosed. Though it has a low incidence, it has significant mortality if the diagnosis is delayed. We are presenting two cases of CTB in newborns who showed signs of disease in the first few days of life. The diagnosis was suspected based on chest computed tomography, magnetic resonance imaging brain, cerebrospinal fluid studies, intrauterine growth restriction, non-response to standard treatment and a maternal history of active tuberculosis. These cases highlight the significance of having a high suspicion of CTB and timely treatment for better outcomes.

Congenital and Perinatal Tuberculosis

This review discusses the recent literature (2006-2020) about the epidemiology, clinical presentation, diagnosis, and management of infants with congenital or perinatal tuberculosis (TB). While the incidence of childhood TB is declining in the United States and worldwide, many case reports describe how clinical suspicion for neonatal TB is raised only if an ill-appearing neonate does not improve with broad-spectrum antibiotics. Furthermore, the delay in initiating appropriate anti-TB therapy often results in the need for significant cardiopulmonary support and/or an increase in mortality. This review summarizes important clinical indications in the maternal and newborn history, the evaluation of an infant with possible TB exposure, and step-by-step recommendations for the treatment and follow-up of infants with TB.

Tuberculosis in a 2.5-month-old infant: congenital or acquired dilemma?

Infants may develop congenital tuberculosis from an infectious mother or acquire the disease postnatally by contact with an infectious adult. Delayed diagnosis is common, especially in infants under 1 year of age, and, if unrecognised, there is an increased risk of death. A 2.5-month-old boy presented with respiratory distress, small inhomogeneous opacities in both lungs and hepatosplenomegaly mimicking sepsis. He had received BCG vaccination and there was no history of contact with tuberculosis (TB). He had had fever since 1 month of age for which there had been several outpatient visits. Gastric aspirate cartridge-based nucleic acid amplification test (CBNAAT) confirmed TB and sonological evaluation demonstrated multiple granulomata in the liver and spleen, and a liver biopsy supported TB. He responded well to 12 months of anti-tuberculous treatment. The mother's tuberculin test, chest radiograph and endometrial biopsy showed no evidence of TB. There was no history of tuberculous contact with close family members. Despite the lack of proof of current tuberculous TB infection in the mother, it is likely that the infant had congenital TB.

Tuberculosis (TB) in pregnancy - A review

Tuberculosis (TB) is a common infectious pathology especially in low-income countries, which may complicate pregnancy. Although pulmonary TB is more common in pregnancy than extra pulmonary TB (EPTB), EPTB is becoming more common especially in those living with human deficiency virus (HIV) co infection or have other comorbidities. The diagnosis of TB may be delayed in pregnancy due to the masking of its symptoms by those of pregnancy. If diagnosed and treated on time both pulmonary TB and EPTB are associated with excellent maternal and perinatal outcome. If, however, there is delay in diagnosis and treatment then there could be adverse maternal and fetal consequences like preterm labour, fetal growth restriction and even stillbirths. Similarly severe forms of TB like disseminated disease (miliary TB) or multi drug resistant TB (MDR TB) are associated with poor outcome. Diagnosis and management is same as in non-pregnant patients. Both drug sensitive pulmonary TB and EPTB are treated with four drugs (isoniazid, rifampicin, pyrazinamide and ethambutol) orally daily for 2 months followed by three drugs (isoniazid, rifampicin and ethambutol) orally daily for 4 months. Drug resistant TB is treated with second line drugs with caution, as some of these drugs are teratogenic. Optimum antenatal care and nutrition therapy along with anti-tuberculosis drugs provide for optimum maternal and perinatal outcome. This review discusses maternal and perinatal outcomes, diagnosis and management of pulmonary TB and extrapulmonary TB as well as perinatal tuberculosis.

A case of early neonate bovine tuberculosis in Ethiopia

This report illustrates that calves may be infected with bovine tuberculosis at early age under natural conditions and progression can be rapid. Thus, testing of calves needs to be considered in any control program to reduce the risk of transmission.

Congenital Tuberculosis in a Neonate: A Case Report and Literature Review

Congenital tuberculosis (TB) is difficult to detect because the disease presents few or no symptoms in the fetus during pregnancy and nonspecific symptoms in neonates. We reviewed 20 cases of congenital TB reported between 2011 and 2017 and report a case of a mother and her 8 days old neonate with congenital TB. In these 21 cases (including our case), the most common clinical presentations were respiratory distress, fever, and hepatosplenomegaly. The most common chest imaging findings were pneumonia, multiple pulmonary nodules, and miliary pattern. The mortality rate of infants with TB was increased ~2.2-fold if their mothers had no symptoms. The case reported herein concerns an 8 days old neonate with the rare presentation of a 2 days history of fever, followed by abdominal distension without respiratory symptoms. Computed tomography (CT) imaging exhibited a large amount of right pleural effusion. Multiple antimicrobial therapies were administered to the neonate; however, his symptoms persisted. Repeat CT was used to identify a progressed disease with multiple nodules over the lung, spleen, and hepatic hilar region. Standard anti-TB medications were prescribed, and the patient recovered gradually. Both gastric lavage and pleural effusion cultures confirmed the diagnosis of TB. The neonate's mother denied any TB contact history and the diagnosis of any medical disease during pregnancy, but she experienced a fulminant course of miliary TB and was admitted to the intensive care unit 24 days postpartum. She died despite receiving anti-TB treatment. In TB-endemic areas, congenital TB should be taken into consideration when neonates develop fever, respond poorly to antimicrobial treatment, and when their mothers deny any TB contact history.
