Objective This study examined whether or not the disease control in Japanese patients with systemic lupus erythematosus (SLE) had improved in recent years and its possible association with altered balance between the use of glucocorticoids and immunosuppressants. Methods We enrolled Japanese patients with SLE who visited our medical center during 2013-2017 (Group A, 75 patients) and compared them with patients encountered during 1999-2003 (Group B, 69 patients; not overlapping with Group A). Patient background characteristics, doses of glucocorticoids, and the use of immunosuppressants at the times of SLE onset and disease flares were reviewed from the medical records. Disease flare was defined as new British Isles Lupus Assessment Group 2004 A or B scores in at least one system. Results Lupus nephritis and neuropsychiatric manifestations were less frequently observed in Group A than in Group B (p=0.042 and p=0.045, respectively). Although the initial glucocorticoid dosage was similar between the groups, the inclusion rate of immunosuppressants in the initial SLE treatment was significantly higher in Group A than in Group B (56% vs. 6% in Group B, p<0.001). The median number of SLE flares per person-year was significantly lower in Group A than in Group B (0 vs. 0.3, respectively, p<0.001), and a propensity score-matched analysis indicated the association of SLE flare with the non-use of immunosuppressants in the initial treatment (p=0.012). The rates of infectious diseases and other complications were similar between the groups. Conclusion The recent aggressive use of immunosuppressants in Japan resulted in a reduction in the rate of SLE flare.

Objective Acute-onset diffuse interstitial lung disease (AoDILD) in patients with rheumatoid arthritis (RA) has been a serious concern, especially for those under treatment with biological agents which may affect the presentation and outcome of AoDILD, including Pneumocystis pneumonia (PCP). Therefore, we conducted a retrospective, multi-center study of AoDILD in RA patients receiving biological agents. Methods Patients who developed AoDILD while receiving biological agents (infliximab, etanercept, adalimumab and tocilizumab) were enrolled in the study. Definite PCP was defined as patients who showed either P. jirovecii organisms in their respiratory samples by microscopic examination, or positive tests for both P. jirovicii DNA-PCR with respiratory samples and an elevated serum 1,3-β-D-glucan level above the cut-off value. Probable PCP was defined as either a positive test for P. jirovicii PCR or an elevated serum β-D-glucan level. Chest HRCT findings were evaluated and scored by two board-certified radiologists. Results The final diagnoses for 26 patients examined were definite PCP for 13 patients, probable PCP for 11, and methotrexate-associated pneumonitis in 2 patients. Definite and probable PCP cases were clinically indistinguishable. Generalized, diffuse ground-glass opacity (GGO) is the characteristic HRCT finding in patients with definite or probable PCP, which was different from our previous findings in RA patients, mostly without biologics, showing GGO distributed in a panlobular or multilobular manner. The clinical outcome was favorable by treatment with trimethoprim-sulfamethoxazole and glucocorticoids. Conclusion The possibility of PCP should be intensively investigated in RA patients developing AoDILD while receiving biological agents.
