Abstract
BACKGROUND
Rheumatic patients have a higher frequency of tuberculosis(TB) than the general population. This study aimed to describe children and adolescents with TB and rheumatic diseases(RD) who were being treated in a reference center.
METHODS
A series of TB cases were investigated in a reference center for childhood TB in Rio de Janeiro, Brazil, from 1995 to 2022.
RESULTS
Fifteen patients with underlying RD and TB were included with 8(53%) being female. The mean age at RD diagnosis was 7.10years (SD ± 0,57 years), and the mean age at TB diagnosis was 9.81 years(SD ± 0.88 years). A total of 9 cases of pulmonary TB(PTB) and 6 cases of extrapulmonary TB-pleural(2), joint/osteoarticular(1), cutaneous(1), ocular(1), and peritoneal(1)- were described. The RD observed in the 15 patients included juvenile idiopathic arthritis(9), juvenile systemic lupus erythematosus(3), juvenile dermatomyositis(1), polyarteritis nodosa(1), and pyoderma gangrenosum(1). Among the immunosuppressants/immunobiologics, methotrexate(8) was the most commonly used, followed by corticosteroids(6), etanercept(2), mycophenolate mofetil(1), cyclosporine A(1), adalimumab(1), and tocilizumab(1). The most common symptoms were fever and weight loss, and a predominance of PTB cases was noted. GeneXpert MTB/RIF® was performed in six patients and was detectable in two without rifampicin resistance; Xpert Ultra® was performed in five patients, and traces with indeterminate rifampicin resistance were detected in three. One female patient discontinued treatment, and another passed away.
CONCLUSIONS
The case series demonstrated the importance of suspecting and investigating TB in RD affected patients who are using immunosuppressants/ immunobiologics, particularly in countries with high rates of TB such as Brazil.
