ABSTRACT

Objective:

To summarize the clinical characteristics and experiences in the diagnosis and treatment of congenital tuberculosis.

Methods:

This study involved four infants with congenital tuberculosis diagnosed in Guangdong Women and Children Hospital from January 2010 to January 2020. Moreover, publications of 52 congenital tuberculosis cases from Chinese hospitals between January 1994 and January 2019 were retrieved from Wanfang Database, China National Knowledge Infrastructure and PubMed. Clinical data of all patients were retrospectively analyzed.

Results:

All four cases we reported here were preterm infants with the onset of the disease at 14-30 d after birth and received anti-tuberculosis treatment. The interval between disease onset and diagnosis was 1-34 d. One baby was cured, one was improved, while the other two died. The median age at the onset of the disease in these 56 cases (including the four we reported and 52 from literature) was 14.5 d (7.0-20.7 d) and the median interval between the onset and diagnosis was 10.5 d (7.5~22.0 d). Forty-eight (88.9%) out of the 54 mothers were suffered from active tuberculosis during the perinatal period, including 16 diagnosed before delivery. The main clinical symptoms in these neonates were fever (82.1%, 46/56), respiratory distress (69.6%, 39/56), drowsiness and/or irritation (57.1%, 32/56), cyanosis (53.6%, 30/56), feeding difficulties (53.6%, 30/56), hepatomegaly (48.2%, 27/56) and splenomegaly (41.1%, 23/56). The positive rates of acid-fast staining, culture and polymerase chain reaction detection of Mycobacterium tuberculosis in sputum smears or gastric juice were all less than 33.3%, and the positive rate of spot test for Mycobacterium tuberculosis infection was 7/12. Chest X-ray showed miliary nodules and diffused nodules-patchy in 37.0% (20/54) and 25.9% (14/54) of the patients, respectively. Abdominal ultrasonography found 52.4% (11/21) with hepatomegaly and/or splenomegaly and 47.6% (10/21) with multiple low-density nodules in liver and spleen. The misdiagnosis rate was 28.6% (16/56). The overall mortality rate was 51.8% (29/56). However, the figure was 28.9% (11/38) in infants with anti-tuberculosis treatment and 18/18 in those without.

Conclusions:

Nonspecific clinical manifestations of congenital tuberculosis, together with low detection rate through laboratory tests, may lead to a higher rate of misdiagnosis and mortality. Therefore, a comprehensive assessment of the mothers of infants with suspected congenital tuberculosis is necessitated. Diagnosis and effective anti-tuberculosis treatment as early as possible are essential to improve the prognosis.
