Abstract: Objective To investigate the clinical characteristics of tuberculosis in patients with different rheumatic diseases, and to provide reference for clinical diagnosis and treatment. Methods Medical records for 220 tuberculosis patients with different rheumatic diseases and 95 ordinary tuberculosis patients in the Third People's Hospital of Shenzhen from January 2012 to December 2018 were retrieved. Clinical characteristics between patients of different rheumatic diseases and patients were described. Results Among 220 patients with rheumatic diseases and tuberculosis, there were 29.10% (64/220) tuberculosis patients with systemic lupus erythematosus (SLE); 35.91% (79/220) with rheumatoid arthritis (RA); 15.91%(35/220) with ankylosing spondylitis(AS); 10.00% (22/220) with sicca syndrome (SS); 5.45% (12/220) with of psoriasis; 3.63% (8/220) with dermatomyositis (DM). In terms of gender distribution, most patients with SLE or SS or DM were female while most patients with AS and psoriasis were male. In terms of age distribution, most patients with SLE were young adults while most patients with RA,SS and PSO were middle-aged and elderly (P<0.0033). In the detection of pathogens, the positive rate of TB-DNA was only statistically different between AS and DM (P<0.0033), and there was a statistical difference of acid-fast bacilli smear positive rate between RA and AS (P<0.0033). Compared to ordinary tuberculosis patients, there were statistical differences in sex, age, tuberculosis type, initial treatment or re-treatment, the positive rate of interferon-gamma release assays, GeneXpert, TB-DNA and mycobacterium culture (P<0.05). Conclusions Tuberculosis patients with SLE, SS and DM are mainly female, while with RA, AS and psoriasis are mainly male; Comparing to ordinary tuberculosis patients, patients with rheumatic diseases have lower positive rate of interferon-gamma release test and lower positive rate of pathogen.
