ABSTRACT
INTRODUCTION:
Contact investigations with drug-susceptible tuberculosis (DS-TB) patients have demonstrated a high prevalence of tuberculosis infection (TBI). However, the prevalence of TBI among individuals in close contact with drug-resistant tuberculosis (DR-TB) patients is poorly understood. This systematic review and meta-analysis aimed to determine the prevalence of TBI among household and non-household contacts of DR-TB patients. METHOD ANDANALYSIS:
We searched five databases (Medline, Embase, Scopus, Web of Science, and Cumulative Index to Nursing and Allied Health Literature (CINAHL)) from inception to 2 June 2023. All studies that reported the prevalence of TBI among DR-TB contacts were included in the study. A random-effects meta-analysis was conducted to estimate the pooled prevalence of TBI with a 95% confidence interval (CI). Sub-group analyses were conducted using study characteristics as covariates.RESULTS:
Thirty studies involving 7659 study participants from 19 countries were included. The pooled prevalence of TBI among DR-TB contacts was 36.52% (95% CI 30.27-42.77). The sub-group analysis showed considerable heterogeneity in the estimates, with the highest prevalence reported in Southeast Asia (80.74%; 95% CI 74.09-87.39), household contacts (38.60%; 95% CI 30.07-47.14), lower-middle-income countries (LMICs) (54.72; 95% CI 35.90, 73.55), children (43.27%; 95% CI 25.50, 61.04), and studies conducted between 2004 and 2012 (45.10; 95% CI 32.44, 57.76).CONCLUSION:
The prevalence of TBI among DR-TB contacts was high, with substantial regional variations. Further research is needed to determine the drug susceptibility status of TBI in DR-TB contacts. PROTOCOL REGISTRATION The protocol is registered in PROSPERO (CRD42023390339).Palavras-chave
