Latent tuberculosis infection reactivation in patients with multiple sclerosis in use of disease-modifying therapies: A systematic review.

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.

Taxa de parto normal versus cesárea em gestantes com uma cesárea anterior e fatores associados / Normal birth rate versus cesarean in pregnant women and associated factors

Objetivo: Calcular taxa de parto vaginal e cesárea em pacientes com uma cesárea anterior e gestação a termo, bem como fatores associados à recorrência de cesaria- na. Métodos: Estudo caso-controle, por meio de dados de prontuário de gestantes a termo com uma cesárea prévia admitidas para parto na Maternidade Darcy Vargas do município de Joinville (SC), em 2019. Resultados: Foram analisadas 788 pacientes, das quais 331 (42,00%) tiveram parto normal (PN) e 457 (58,00%), cesárea (CS). O grupo PN foi composto por mulheres mais velhas (29; 28) e com mais gestações que o grupo CS, possuindo pelo menos um parto normal prévio (171; 57; p < 0,001). Como fator de risco para recorrência de cesárea, destacou-se a presença de colo desfavorável no momento do parto (47; 356; p < 0,001). Internação por trabalho de parto (284; 92; p < 0,001) e ruptura prematura de membranas (RUPREME) (33; 79; p = 0,030) estão entre os fatores de proteção para ocorrência de uma nova cesariana. Conclusão: A taxa de parto vaginal pós-cesariana (VBAC) foi de 42% e a de parto cesáreo foi de 58%, condi- zente com valores de referência mundiais. O fato de ter um ou mais partos normais anteriores e internar-se em trabalho de parto ou com RUPREME foi fator protetor contra a repetição da cesárea, enquanto o colo desfavorável no momento da inter- nação foi fator de risco. Há grande divergência na literatura, sendo necessários mais estudos para elaborar estratégias que auxiliem profissionais e pacientes a decidirem pela melhor via de parto após cesariana anterior.(AU)

Objective: To calculate the rate of vaginal and cesarean delivery in patients with pre- vious cesarean section and pregnancy to term, as well as factors associated with recur- rent abdominal delivery. Methods: Case-control study, by medical records of pregnant women to term with a previous cesarean section admitted for delivery at Maternity Dar- cy Vargas in the city of Joinville (SC) in 2019. Results: 788 patients, of which 331 (42,00%) had a normal delivery (PN) and 457 (58,00%) cesarean section (CS). The PN group was composed of older women (29;28), and who had more pregnancies than the CS group, having at least 1 previous vaginal birth (171; 57; p < 0,001). As a risk factor for cesarean recurrence, the presence of an unfavorable cervix at the time of delivery was highlighted (47; 356; p < 0,001). Hospitalization for labor (284; 92; p < 0,001) and premature rupture of membranes (33; 79; p = 0,030) are among the protective factors for the occurrence of a new cesarean section. Conclusion: The post-cesarean vaginal birth (VBAC) rate was 42% and the cesarean delivery rate was 58%, consistent with world reference values. The fact of having one or more previous normal bir- ths, hospitalization in labor or with premature rupture of fetal membranes were protective factors against the repetition of cesarean section, while the unfavorable cervix at the time of hospitalization was a risk factor. There is divergence in litera- ture, therefore more studies are needed to develop strategies that help professionals and patients to decide on the best way of delivery after a previous cesarean section.(AU)
