Adjunctive corticosteroid therapy in patients with pulmonary tuberculosis.

OBJECTIVES: In tuberculosis treatment, corticosteroids are used as adjuvants, especially in meningeal/pericardial tuberculosis. In other forms of the disease, especially in severe tuberculosis requiring mechanical ventilation, its use is controversial. The aim of the present study is to assess whether the use of corticosteroids in the treatment of pulmonary tuberculosis patients in mechanical ventilation is associated with in-hospital mortality. METHODS: This is a retrospective cohort study. Tuberculosis patients >18 years requiring mechanical ventilation, admitted to the emergency department or intensive care unit, were included. Data on corticosteroid use and mortality were collected. RESULTS: In total, 467 patients were included in the analysis; 399 used corticosteroids and 68 were noncorticosteroid users. The mortality rate was higher among corticosteroid users (59.9%) than in noncorticosteroid users (41.2%) (p=0.010). The total dose of corticosteroid in prednisone equivalents was not different between survivors and nonsurvivors (median [interquartile range]: 80 mg [5-56.6 mg] vs. 80 mg [50-135 mg]; p=0.881). CONCLUSIONS: Tuberculosis patients in mechanical ventilation who used corticosteroids had a higher mortality rate than those who did not use corticosteroids. The role of corticosteroids in pulmonary tuberculosis, especially in critically ill patients, remains unclear and needs further evaluation in prospective studies.

Tuberculosis in the intensive care unit: alternative treatment regimens and association with mortality.

OBJECTIVES: Adequate anti-tuberculosis (TB) treatment is an important factor that can affect the patient's outcome. Higher mortality is found in patients who do not receive optimal treatment that includes isoniazid and rifampicin. The objective of this study is to evaluate the association of use of alternative TB treatment regimens (without rifampicin and isoniazid) and mortality among patients requiring intensive care. METHODS: Retrospective cohort study, from January 2010 to December 2018. Patients aged > 18 years with a TB diagnosis, admitted to the ICU of a general, tertiary care, university-affiliated hospital (Hospital de Clínicas de Porto Alegre - HCPA) were included. Data on TB treatment used and outcomes of treatment were collected. RESULTS: 462 patients met the inclusion criteria and were included in the analysis; 284 used the usual treatment regimen (rifampicin, isoniazid, pyrazinamide and ethambutol - all orally), and 178 used alternative treatment regimens (IV levofloxacin plus oral ethambutol plus IM streptomycin or IV amikacin, without rifampicin and isoniazid). The mortality was higher among users of alternative treatment regimens (63.5%) than among usual treatment regimen users (51.4%) (P = 0.011). In a multivariate analysis, age, albumin and death were independently associated with alternative treatment regimens use. CONCLUSIONS: TB programmes in which IV rifampicin is not widely available should consider including it, especially for critically ill TB patients, for whom there may be improved survival.

OBJECTIFS: Un traitement antituberculeux (TB) adéquat est un facteur important pouvant influencer les résultats du patient. Une mortalité plus élevée est observée chez les patients qui ne reçoivent pas un traitement optimal comprenant de l'isoniazide et de la rifampicine. L'objectif de cette étude est d'évaluer l'association entre l'utilisation d'autres schémas thérapeutiques anti-TB (sans rifampicine ni isoniazide) et la mortalité chez les patients nécessitant des soins intensifs. MÉTHODES: Etude de cohorte rétrospective, de janvier 2010 à décembre 2018. Les patients âgés de >18 ans avec un diagnostic de TB, admis à l'unité de soins intensifs d'un hôpital général, avec des soins tertiaires, affilié à l'Université (Hôpital de Clínicas de Porto Alegre-HCPA) ont été inclus. Des données sur le traitement anti-TB utilisé et les résultats du traitement ont été collectés. RÉSULTATS: 462 patients répondaient aux critères d'inclusion et ont été inclus dans l'analyse; 284 ont utilisé le schéma thérapeutique habituel (rifampicine, isoniazide, pyrazinamide et éthambutol - tous par voie orale) et 178 ont utilisé des schémas thérapeutiques alternatifs (lévofloxacine IV plus éthambutol oral plus streptomycine IM ou amikacine IV, sans rifampicine ni isoniazide). La mortalité était plus élevée chez les utilisateurs de schémas thérapeutiques alternatifs (63,5%) que chez les utilisateurs de schémas thérapeutiques habituels (51,4%) (P = 0,011). Dans l'analyse multivariée, l'âge, l'albumine et le décès ont été indépendamment associés à l'utilisation de schémas thérapeutiques alternatifs. CONCLUSIONS: Les programmes de lutte contre la TB dans lesquels la rifampicine IV n'est pas largement disponible devraient envisager de l'inclure, en particulier pour les patients atteints de TB et sévèrement malades, pour lesquels la survie peut être améliorée.
