First data on latent tuberculosis infection in Syrian refugees with diabetes in Lebanon.

OBJECTIVE

The association between diabetes mellitus and tuberculosis is a health-threatening double trouble. Vulnerable populations such as refugees and conflict-displaced populations may be at higher risk of both diseases. Here, we examined the prevalence of latent tuberculosis infection (LTBI) and its associated risk factors in a population of Syrian refugees with diabetes in North Lebanon.

STUDY

DESIGN

This is a cross-sectional study.

METHODS

A total of 87 Syrian refugees with diabetes were enrolled. Demographic and clinical data were collected using a structured questionnaire, and a blood sample was obtained from each patient. LTBI was examined using the last generation QuantiFERON-TB Gold Plus assay.

RESULTS

The mean age of the study population was 54.1 ± 10.5 years, and the majority were women (79.3%). LTBI was found in 1 in 5 (17/87; 19.5%) enrolled patients, with the majority being originated from Aleppo (47.05%). Infection was significantly associated only with age (P = 0.009), and its risk was 4-fold higher in patients aged ≥60 years (odds ratio: 4.1, confidence interval: 1.4-12.5, P = 0.018).

CONCLUSION

This study highlights the need to implement effective tuberculosis control strategies among refugees with diabetes, with particular attention to those at older age.
