Abstract

Background: Tuberculosis (TB) is an infectious-contagious disease caused by Mycobacterium tuberculosis. This disease can act acutely or in latent form as granuloma. Multiple Sclerosis (MS) is a chronic inflammatory disease more common in the Central Nervous System (CNS). Its treatment involves disease-modifying therapies (DMTs), which can predispose MS patients to a higher risk of infections by interfering in the immune system. Patients undergoing MS treatment could be more susceptible to Latent Tuberculosis Infection (LTBI) reactivation. This study aims to elucidate the possible relationship between MS and LTBI through a systematic review of the literature.

Methods: MEDLINE/PubMed, Cochrane, ScienceDirect, LILACS, and SciELO were systematically reviewed from 2010 to 2020 and Google Scholar from 2015 to 2020 to detect eligible papers. The following keywords were used for this search: "LTBI and MS"; "Multiple Sclerosis and Latent Tuberculosis"; "Multiple Sclerosis and Latent Tuberculosis infection reactivation"; "Multiple Sclerosis and Pulmonary Tuberculosis"; "Multiple Sclerosis and Active Tuberculosis"; "Multiple Sclerosis and Tuberculosis Reactivation" for MEDLINE/Pubmed and ScienceDirect; and "Multiple Sclerosis and Latent Tuberculosis Infection" for Google Scholar, Cochrane, SCIELO, and LILACS. The filter for "review articles," "research articles," and "case reports" was applied in ScienceDirect.

Results: Fourteen (14) studies describing the relationship between MS and LTBI were included in qualitative synthesis: case-report (2), prevalence (2), non-systematic review (4), expert consensus (2), and case-control (4) studies.

Conclusion: The reactivation of LTBI is well understood, but hardly any literature addressed the association between the contagious disease and MS' treatment. The selected articles are observational studies that offer limited data and differ in many aspects detailed over this study. These divergences make it challenging to compare articles' results. Nevertheless, most reports recommend screening for LTBI before starting MS treatment, mainly in high incidence countries.
