Mycobacterium tuberculosis Infection and the development of laryngeal stenosis in children — is there a relationship?

Abstract

The aim is to study the relationship of Mycobacterium tuberculosis infection and the development of laryngeal stenosis (croup) in children. 250 children with croup aged from 6 months to 8 years were examined.It was found that infection with Mycobacterium tuberculosis in children with laryngeal stenosis (croup) developed at the age of under 4 years. The first episode of croup coincided in 90% of cases with the early period of primary infection with Mycobacterium tuberculosis. A high proportion of close contact with adult tuberculosis patients reached 35% in patients with recurrent laryngeal stenosis (croup). The incidence of tuberculosis among children with repeated episodes of croup was 30%. Anti-TB therapy for latent tuberculosis infection or local forms of tuberculosis led to the cessation of repeated episodes of croup in 85% of cases. Infection with Mycobacterium tuberculosis and active tuberculosis infection is considered as one of the factors contributing to the recurrent course of laryngeal stenosis in children.
