Pediatric tuberculosis in the metropolitan area of Rio de Janeiro

Missed opportunities in the prevention and diagnosis of pediatric tuberculosis: a scoping review

OBJECTIVES

Identify potential barriers, delays, and missed opportunities in the prevention and diagnosis of childhood TB.

METHODS

Scoping review according to the PRISMA extension. The definitions considered for the selection followed the acronym PCC where the population (P) is children under 18 years of age with TB disease, the concept (C) refers to missed opportunities for prevention and diagnosis, and context (C) is defined as a diagnosis of TB disease. The authors searched systematically in the databases; VHL/Lilacs, Medline via PubMed, Cochrane, Scopus, and Web of Science, without date or language limitation.

RESULTS

Seven studies were included. In developed countries, with low disease burden, the main shortcoming is the delay in diagnosing bacilliferous adults in contact with young children. This problem is concentrated in the portion of the population with socioeconomic vulnerability. In underdeveloped countries, with a high burden of disease, the biggest challenge is tracking children who come into contact with bacilliferous patients.

CONCLUSIONS

There are still many missed opportunities in the prevention and diagnosis of childhood TB. The positive legacy of the COVID-19 pandemic should be taken advantage of and the encouragement of scientific development in the management of infectious diseases should be taken.

Treatment outcome of pediatric tuberculosis in eastern Ethiopia

BACKGROUND

Children are more vulnerable to developing active Mycobacterium tuberculosis infection which causes significant morbidity and mortality. However, the contribution of childhood tuberculosis and its treatment outcomes have not been well documented, and no research has been conducted in eastern Ethiopia.

OBJECTIVE

This study aimed to assess the treatment outcome and its predictors of pediatric tuberculosis in eastern Ethiopia from September 1, 2017 to January 30, 2018.

METHODS

A retrospective study was conducted in eight selected hospitals in eastern Ethiopia. Data on 2002 children with tuberculosis was extracted by using the standard checklist of the national tuberculosis treatment format. Treatment outcomes were determined according to the standard definitions of the National Tuberculosis and Leprosy Control Programme. Data were entered into Epi Data software version 3.1 and exported to Statistical Package for Social Science (SPSS) version 20 for analysis. Bivariable and multivariable regression analyses were carried out to examine the associations between dependent and independent variables. A P-value of <0.05 was considered statistically significant.

RESULT

The overall successful treatment rate was 1,774 (88.6%) [95% confidence interval (CI): (80.59-97.40)]. A total of 125 (6.2%), 1,648 (82.3%), 59 (2.9%), and 19 (0.9%) children with tuberculosis (TB) were cured, completed, defaulted, and died, respectively. A high number of defaulters and deaths were reported in the age group <10 years. More children with smear-positive pulmonary TB (74.4%) were cured, while smear-negative tuberculosis had higher treatment completion rates. Being male in sex (adjusted odds ratio (AOR): 0.71, 95% CI: 0.53, 0.96) and those with human immunodeficiency virus (HIV) positive sero status (AOR: 0.51, 95% CI: 0.29, 0.90) had a lower chance of a successful treatment outcome.

CONCLUSION

In this study, thee treatment success rate was higher than the recent World Health Organization report. Those males and HIV seropositive status were less likely to have a successful treatment outcome. Therefore, efforts should be made by each health institution in eastern Ethiopia by giving emphasis on male and HIV-positive individuals.

Tuberculosis among children and adolescents in Rio de Janeiro, Brazil - Focus on extrapulmonary disease

OBJECTIVE

To compare the socio-demographic, clinical, and diagnostic characteristics and treatment outcomes between extrapulmonary tuberculosis (EPTB) and pulmonary tuberculosis (PTB) in children and adolescents in Rio de Janeiro, a high TB-burdened Brazilian city.

METHODS

This retrospective study used data from patients with EPTB and PTB aged 0 - 18 years, notified on two national databases from 2014 to 2016.

RESULTS

Among the 1008 patients, 144 (14.2%) had EPTB. Patients with EPTB showed higher odds of hospital-based diagnosis (odds ratio (OR): 6.76 [95% confidence interval (95% CI): 4.62-9.90]; p < 0.001), no laboratory confirmation (OR: 4.9 2.14 [95% CI: 3.07 - 7.85]; p < 0.001), and being <14 years old (OR: 3.13 [95% CI: 2.18-4.49]) than those with PTB. A diagnosis without laboratory investigation was observed among 301/864 (34.8%) patients with PTB, 48/144 (33.3%) with EPTB, and among those aged under five years with EPTB (15/27 [55.6%]). TB deaths were more frequent in patients with EPTB (5/144 [3.5%]) than in those with PTB (4/864[0.5%]) (p = 0.001); 4/5 (80%) TB deaths were due to TB meningitis; 50% died within 14 days of diagnosis.

CONCLUSIONS

EPTB remains a clinical diagnostic challenge that needs to be addressed to fully benefit from the higher sensitivity laboratory investigations.
