RESUMEN
OBJECTIVES: To investigate trends in the treatment of patients with late-onset rheumatoid arthritis (LORA) using data from the National Database of Rheumatic Diseases in Japan (NinJa). METHODS: Patients registered in the NinJa were classified according to disease onset: at <65 years (young-onset rheumatoid arthritis [YORA]); at 65-74 years (early LORA); and at ≥75 years (late LORA). Chronological changes in the treatment and disease activity were compared. RESULTS: A total of 7,178, 13,171, 15,295, and 15,943 patients were evaluated in 2010, 2013, 2016, and 2019, respectively. In all groups, the use of methotrexate gradually decreased, whereas that of biological/targeted synthetic disease-modifying antirheumatic drugs (DMARDs) increased; the use of tumor necrosis factor inhibitors (TNFi) decreased, whereas that of non-TNFi increased. LORA was characterized by more single DMARD use, and less methotrexate and biological/targeted synthetic DMARD use. TNFi and interleukin-6 inhibitors were used less frequently, whereas abatacept was utilized more frequently in late versus early LORA. Conventional synthetic DMARD (excluding methotrexate) and glucocorticoid use was higher in late versus early LORA. CONCLUSIONS: This analysis revealed chronological changes in the treatment of LORA in Japan. Differences between early and late LORA suggest that patients are not a homogeneous population.
RESUMEN
OBJECTIVE: In this study, we examine how advancements in novel antirheumatic drugs affect the clinicopathologic features of lymphoproliferative disorder (LPD) in patients with rheumatoid arthritis (RA). METHODS: In this multicenter study across 53 hospitals in Japan, we characterized patients with RA who developed LPDs and visited the hospitals between January 1999 and March 2021. The statistical tools used included Fisher's exact test, the Mann-Whitney U-test, the log-rank test, logistic regression analysis, and Cox proportional hazards models. RESULTS: Overall, 752 patients with RA-associated LPD (RA-LPD) and 770 with sporadic LPD were included in the study. We observed significant differences in the clinicopathologic features between patients with RA-LPD and those with sporadic LPD. Histopathological analysis revealed a high frequency of LPD-associated immunosuppressive conditions. Furthermore, patients with RA-LPD were evaluated based on the antirheumatic drugs administered. The methotrexate (MTX) plus tacrolimus and MTX plus tumor necrosis factor inhibitor (TNFi) groups had different affected site frequencies and histologic subtypes than the MTX-only group. Moreover, MTX and TNFi may synergistically affect susceptibility to Epstein-Barr virus infection. In case of antirheumatic drugs administered after LPD onset, tocilizumab (TCZ)-only therapy was associated with lower frequency of regrowth after spontaneous regression than other regimens. CONCLUSION: Antirheumatic drugs administered before LPD onset may influence the clinicopathologic features of RA-LPD, with patterns changing over time. Furthermore, TCZ-only regimens are recommended after LPD onset.

BACKGROUND: Organizing pneumonia (OP) is recognized as a nonspecific lung injury response characterized histopathologically by the presence of intra-alveolar buds of granulation tissue. Most OP patients show excellent responses to corticosteroids, but relapse is frequently seen when corticosteroids are tapered or discontinued. Although several factors associated with relapse have been reported in cryptogenic OP (COP), the clinical features and risk factors associated with relapse in connective tissue disease-associated OP (CTD-OP) have yet to be fully understood. METHODS: We retrospectively reviewed data on 47 CTD-OP patients. We investigated the frequency of relapse and compared the clinical data between CTD-OP with and without relapse to clarify the risk factors for relapse. RESULTS: Eleven (23.4%) CTD-OP patients had relapses of OP during the study. In the multivariate analysis, no CTD treatment at OP diagnosis [O.R. 11.920, p = 0.012] and partial remission after steroid treatment [O.R. 35.944, p = 0.045] were independent risk factors for relapse. Among rheumatoid arthritis-associated OP (RA-OP) patients, partial remission after steroid treatment [O.R. 16.151, p = 0.047] and age at OP diagnosis [O.R. 0.899, p = 0.045] were independent risk factors for relapse. Most of the relapsed OP patients who were on no medication at OP diagnosis later developed CTD. CONCLUSION: CTD-OP patients with residual disease on HRCT after treatment and who had OP diagnosis preceding CTD diagnosis were more likely to have an OP relapse. During the clinical course of relapsed OP patients, it is necessary to pay attention to the onset of CTD.

This is a case of a 55-year-old man who presented with cough and anterior chest pain. Tracheal biopsy confirmed the diagnosis of relapsing polychondritis (RP). Although the patient had circumferential bronchial wall thickening extending to the tracheomembranous area and was positive foRPR3-ANCA, he did not meet the diagnostic criteria for granulomatosis with polyangiitis. The patient was refractory to prednisolone + methotrexate + azathioprine and responded to adalimumab, a biologic tumor necrosis factor-α inhibitor effective in RP refractory cases. Herein, we report a rare case of RP with circumferential bronchial wall thickening extending to the tracheomembranous area.

BACKGROUND: Acute exacerbation (AE) is a life-threatening clinical event that occurs during the clinical course of idiopathic pulmonary fibrosis (IPF). Several studies have reported that AE also occurs in interstitial lung disease (ILD) other than IPF. However, the incidence, clinical features, risk factors for AE, and major causes of death in antineutrophil cytoplasmic antibody (ANCA)-associated ILD (ANCA-ILD) patients have not been well established. METHODS: We retrospectively reviewed the data of 54 ANCA-ILD patients and 304 IPF patients. We investigated the frequency of AE, post-AE prognoses, risk factors for AE, and major causes of death in ANCA-ILD patients. We also compared the data of ANCA-ILD with that of IPF. RESULTS: Fourteen (25.9%) ANCA-ILD patients and 84 (27.6%) IPF patients developed AE. The median survival times (MSTs) after AE in ANCA-ILD and IPF patients were 35.5 and 60 days, respectively (p = 0.588, log-rank test). In a multivariate analysis, the percentage of predicted forced vital capacity (%FVC) [O.R. 0.750 (95% CI 0.570, 0.986), p < 0.01] and serum C-reactive protein (CRP) [O.R. 2.202 (95% CI 1.037, 4.674), p < 0.01] were independent risk factors for AE. AE was the most frequent cause of death in ANCA-ILD and IPF patients. CONCLUSION: ANCA-ILD patients could develop AE, and the frequency of AE in ANCA-ILD is similar to that in IPF. AE is the most frequent cause of death in ANCA-ILD patients. A low %FVC and a high serum CRP level were independent predictive factors for AE in ANCA-ILD. The prognosis after AE in ANCA-ILD was poor, as it was in IPF.

BACKGROUND: To analyse the subsequent clinical course of patients with rheumatoid arthritis (RA) who either continued or discontinued biologic agents after hospitalization for infections. METHODS: We retrospectively reviewed the clinical records of 230 RA patients with 307 hospitalizations for infections under biologic therapy between September 2008 and May 2014 in 15 institutions for up to 18 months after discharge. The risks of RA flares and subsequent hospitalizations for infections from 61 days to 18 months after discharge were evaluated. RESULTS: Survival analyses indicated that patients who continued biologic therapy had a significantly lower risk of RA flares (31.4% vs. 60.6%, P < 0.01) and a slightly lower risk of subsequent infections (28.7% vs. 34.5%, P = 0.37). Multivariate analysis showed that discontinuation of biologic therapy, diabetes, and a history of hospitalization for infection under biologic therapy were associated with RA flares. Oral steroid therapy equivalent to prednisolone 5 mg/day or more and chronic renal dysfunction were independent risk factors for subsequent hospitalizations for infections. CONCLUSIONS: Discontinuation of biologic therapy after hospitalization for infections may result in RA flares. Continuation of biologic therapy is preferable, particularly in patients without immunodeficiency.

BACKGROUND: Several studies have reported that acute exacerbation (AE), which occurs during the clinical course of idiopathic pulmonary fibrosis (IPF), also occurs in rheumatoid arthritis-associated interstitial lung disease (RA-ILD). However, the incidence, clinical features, and risk factors for AE, a major cause of death of RA-ILD patients, and the differences in clinical aspects of AE between RA-ILD and IPF have yet to be fully understood. METHODS: We retrospectively reviewed data on 149 RA-ILD patients and 305 IPF patients. We investigated the frequency of AE and compared the clinical data between RA-ILD with and without AE to clarify the risk factor for AE. We also compared the post-AE prognosis and cause of death between RA-ILD and IPF patients. RESULTS: Twenty-seven (18.1%) RA-ILD patients and 84 (27.5%) IPF patients developed AE. The median survival time (MST) after AE of RA-ILD and IPF was 277 days and 60 days, respectively (log rank, p = 0.038). In a multivariate analysis, hypoalbuminemia [odds ratio (O.R.) 0.090 (95%CI 0.011-0.733), p = 0.012] and % carbon monoxide diffusion capacity (%DLCO) [O.R. 0.810 (95%CI 0.814-0.964), p < 0.01] were independent risk factors for AE. AE was the most frequent cause of death of RA-ILD and IPF. CONCLUSION: RA-ILD patients could develop AE, and AE was not uncommon in RA-ILD or IPF. %DLCO and hypoalbuminemia were predictive factors of AE in RA-ILD. The prognosis after AE of RA-ILD was significantly better than that of IPF. The most frequent cause of death in RA-ILD and IPF was AE.

Abatacept may exert its clinical effect on rheumatoid arthritis (RA) by suppressing anti-cyclic citrullinated peptide (CCP) antibody production. This study was undertaken to test this hypothesis by examining the changes of disease activity of RA and anti-CCP antibody levels over time after starting abatacept. Sixty Japanese RA patients who started abatacept were included in this multicenter, prospective observational study. Simple Disease Activity Index (SDAI) and anti-CCP antibody levels were evaluated at 12, 24, and 52 weeks. The mean SDAI score significantly decreased within 12 weeks after starting abatacept and was maintained thereafter. On the contrary, the mean anti-CCP antibody levels did not change until 52 weeks. At the individual level, there were substantial changes of anti-CCP antibody levels, but these were not correlated with the changes of disease activity at any time points. Thus, abatacept reduces the disease activity of RA independently of modulating anti-CCP antibody production.

Objectives: To investigate the efficacy of suppressing joint destruction with subcutaneous tocilizumab (TCZ-SC) for Japanese rheumatoid arthritis (RA) patients in the real-world clinical setting.Methods: This 1-year prospective, multicenter study included 110 RA patients in whom TCZ-SC was newly initiated. Primary endpoint was the change from baseline in vdH-modified total Sharp score (mTSS) at week 52. Structural remission was defined as yearly mTSS of 0.5 or less. Disease activity was evaluated using the disease activity score (DAS28-ESR) and clinical disease activity index (CDAI).Results: At baseline, the patients' mean age was 58.6 years, and the mean disease duration was 10.6 years. The proportion of patients who were naïve for biologics was 44.5%, and 64.5% concomitantly received methotrexate. The yearly mTSS showed significant improvement from 9.41 before TCZ-SC initiation to -0.15 after 52 weeks. The structural remission rate was 76.1%. After 52 weeks, the DAS28-ESR and CDAI remission rates were 52% and 21%, respectively. Although the previous usage of biologics and baseline disease activity significantly affected the clinical remission, no factors with significant effects on structural remission were identified.Conclusion: These findings support the efficacy of TCZ-SC in suppressing disease activity as well as joint destruction over a 1-year period.

OBJECTIVE: Knowing the risk of hospitalized infection associated with individual biological agents is an important factor in selecting the best treatment option for patients with rheumatoid arthritis (RA). This study examined the comparative risk of hospitalized infection between biological agents in a routine care setting. METHODS: We used data for all RA patients who had first begun biological therapy at rheumatology divisions of participating community hospitals in Japan between January 2009 and December 2014. New treatment episodes with etanercept, infliximab, adalimumab, abatacept, or tocilizumab were included. Patients were allowed to contribute multiple treatment episodes with different biological agents. Incidence rates (IRs) of hospitalized infection during the first year of follow-up were examined. Cox regression analysis was used to calculate hazard ratios (HRs) for overall hospitalized infection and for pulmonary hospitalized infection, adjusting for possible confounders. RESULTS: A total of 1596 new treatment episodes were identified. The incidence of overall hospitalized infection during the first year was 86 with 1239 person-years (PYs), yielding a crude IR of 6.9 per 100 PYs (95% confidence interval [CI], 5.6-8.6). After correction for confounders, no significant difference in risk of hospitalized infection was observed between treatment groups: adjusted HRs (95% CI) were 1.54 (0.78-3.04) for infliximab, 1.72 (0.88-3.34) for adalimumab, 1.11 (0.55-2.21) for abatacept, and 1.02 (0.55-1.87) for tocilizumab compared with etanercept. Patient-specific factors such as age, RA functional class, body mass index (BMI), prednisolone use, and chronic lung disease contributed more to the risk of hospitalized infection than specific biological agents. The incidence of pulmonary hospitalized infection was 50 and a crude IR of 4.0 per 100 PYs (95% CI, 3.1-5.3). After adjustment for confounders, adalimumab had a significantly higher HR for pulmonary hospitalized infection compared with tocilizumab: an adjusted HR (95% CI) was 4.43 (1.72-11.37) for adalimumab. BMI, prednisolone use, diabetes mellitus, and chronic lung disease were also significant factors associated with the risk of pulmonary hospitalized infection. CONCLUSIONS: The magnitude of the risk of overall hospitalized infection was not determined by the type of biological agents, and patient-specific risk factors had more impact on the risk of hospitalized infection. For pulmonary hospitalized infections, the use of adalimumab was significantly associated with a greater risk of this complication than tocilizumab use.

OBJECTIVE: Upper limit of methotrexate (MTX) for patients with rheumatoid arthritis (RA) was recently increased from 8 to 16 mg/week in Japan. We therefore examined the effect of concomitant MTX dose on the efficacy of adalimumab (ADA) in clinical practice. METHOD: Sixty-one consecutive RA patients treated with ADA were followed for minimum 52 weeks and retrospectively compared by MTX dose; patients receiving concomitant MTX of 10 mg/week or more (MTX ≥10 mg group) and <10 mg/week (MTX <10 mg group). Disease activity and remission were evaluated by the disease activity score 28 (DAS28) criteria. RESULTS: The MTX ≥10 mg group consistently showed better improvement in DAS28 and resulted in more patients (52.8%) with DAS28-remission compared with the MTX <10 mg group (26.1%). Multivariate analysis showed that MTX ≥10 mg had a significant effect on DAS28 remission with odds ratio of 5.12. ADA retention rate was 72.2% in MTX ≥10 mg group compared with 52.0% in MTX <10 mg group. Discontinuation of ADA due to adverse events were comparable in the MTX ≥10 mg and MTX <10 mg groups (11.1% vs. 12.0%). CONCLUSIONS: These findings support the critical role of concomitant MTX in the efficacy of ADA, and recommend use of MTX ≥10 mg in Japanese RA patients.

INTRODUCTION: Patients with rheumatoid arthritis (RA) treated with abatacept (ABT) are at increased risk for vaccine-preventable infections. The aim of the present study is to evaluate the humoral response to 23-valent pneumococcal polysaccharide (PPSV23) vaccination in RA patients receiving ABT. METHODS: The immunogenicity study was nested within a randomized, double-blind placebo-controlled study, designed to evaluate the efficacy of the PPSV23. PPSV23 was given to 111 RA patients, who were classified into three groups: RA control (n = 35), methotrexate (MTX) alone (n = 55), and ABT (n = 21). Before and 4-6 weeks after vaccination, we measured the patients' concentrations of antibodies against pneumococcal serotypes 6B and 23F using an enzyme-linked immunosorbent assay and determined their antibody functionality using a multiplexed opsonophagocytic killing assay, reported as the opsonization index (OI). RESULTS: The pneumococcal serotype-specific IgG concentrations and OIs were both significantly increased in all treatment groups in response to PPSV23 vaccination. In the ABT group, the IgG responses for the 6B serotype were lower compared with those in the MTX alone or control groups, whereas the OI responses were similar to those in the other two groups. In a subgroup analysis, the pneumococcal serotype-specific IgG responses were significantly lower in both serotypes (6B and 23F) in the ABT/MTX group; however, the OI responses in the ABT group were not different from the control group. There was no association between the pneumococcal serotype-specific IgG and OI responses for the 6B serotype in patients receiving ABT in contrast to the control or MTX alone patients. No severe adverse effects were observed in any of the treatment groups. CONCLUSIONS: OI responses indicate antibody functionality rather than simply their amount, so the similarity of these measurements between all three groups suggests that RA patients receiving ABT still benefit from receiving the PPSV23 vaccination, even though they produce less IgG in response to it. The results suggest an influence of ABT on the humoral response to PPSV23 vaccination under MTX treatment; however, preserved opsonin responses are expected in RA patients treated with ABT plus MTX.

INTRODUCTION: In rheumatoid arthritis (RA) patients receiving immunosuppressive treatments, vaccination against Streptococcus pneumoniae is recommended. The objective of the study was to evaluate the effects of tacrolimus (TAC) on immune response following administration of a 23-valent pneumococcal polysaccharide vaccine (PPSV23) in patients with established RA. METHODS: Patients with RA (n = 133) were vaccinated with PPSV23. Patients were classified into TAC (n = 29), methotrexate (MTX) (n = 55), control (n = 35), and TAC/MTX (n = 14) treatment groups. We measured the concentrations of pneumococcal serotypes 6B and 23F by using an enzyme-linked immunosorbent assay and determined antibody functionality by using a multiplexed opsonophagocytic killing assay, reported as the opsonization index (OI), before and 4 to 6 weeks after vaccination. A positive antibody response was defined as at least a twofold increase in the IgG concentration or as at least a 10-fold increase in the OI. RESULTS: IgG concentrations and OIs were significantly increased in all treatment groups after PPSV23 vaccination. The TAC treatment group appears to respond in a manner similar to that of the RA control group in terms of 6B and 23F serotype concentration and function. In contrast, the MTX group had the lowest immune response. Patients who received a combination of TAC and MTX (TAC/MTX) also had a diminished immune response compared with those who received TAC alone. CONCLUSIONS: TAC monotherapy does not appear to impair PPSV23 immunogenicity in patients with RA, whereas antibody production and function may be reduced when TAC is used with MTX. Thus, PPSV23 administration during ongoing TAC treatment should be encouraged for infection-prone TAC-treated patients with rheumatic diseases.

We studied the clinico-pathological differences among PR3-ANCA-positive granulomatosis with polyangiitis (PR3-GPA), MPO-ANCA-positive GPA (MPO-GPA) and microscopic polyangiitis (MPA). ANCA-associated vasculitis (AAV) was classified using the European Medicines Agency classification. We retrospectively analyzed 38 patients with GPA and 41 with MPA treated in eight hospitals in Japan. Of the patients with GPA, 17 were positive for MPO-ANCA, and 15 for PR3-ANCA. All patients with MPA were MPO-ANCA positive. The mean ages of those with MPO-GPA were 69.6 years old, 10 years older than those with PR3-GPA. The majority (82 %) of patients with MPO-GPA were woman, a significantly greater proportion than for PR3-GPA. We also found that ear, nose and throat (ENT), nervous system involvement were significantly more common in MPO-GPA, but renal function was less impaired than those with MPA. Both PR3-GPA and MPO-GPA relapsed more frequently than MPA, but overall survival was significantly better (P < 0.01 and P < 0.05, respectively). Univariate analysis identified the following factors as predictors of a poor prognosis: MPA (P < 0.01), pulmonary UIP pattern (P < 0.005) Cr ≥ 1.7 mg/dl (P < 0.01) and absence of ENT involvement (P < 0.05), which were characteristics of MPA. In our cohort, MPO-GPA was most likely to affect older women and was associated with otitis media, nervous system involvement, mild renal impairment and more favorable outcome. It is clinically useful to differentiate MPO-GPA from MPA and PR3-GPA in patients with AAV.

Interstitial lung disease (ILD) has a heterogeneous clinical presentation and establishing prognosis for these patients is challenging. We investigated the clinical characteristics and outcome of patients with idiopathic interstitial pneumonias (IIPs) and patients with connective tissue disease-associated interstitial lung disease (CTD-ILD). We conducted a multicenter prospective study on 104 patients diagnosed with IIPs and 29 patients diagnosed with CTD-ILD, which were newly diagnosed and treated with corticosteroids initially. We compared the clinical characteristics, high-resolution computed tomography (HRCT) imaging date, and outcomes. Cox proportional hazard regression analysis was used to identify variables with increased risk of death. Survival was analyzed according to the Kaplan-Meier method and was assessed with the log-rank test. Of 133 patients with IIPs (nâ=â104) or CTD-ILD (nâ=â29), 44 patients died during the follow-up period (mean: 1.6â±â0.78 years). Patients with IIPs seemed to be associated with worse survival compared with those with CTD-ILD; however, this difference was not significant (log-rank test, Pâ=â0.084). Significant predictors for mortality in patients with IIPs at baseline were lower for performance status and definite usual interstitial pattern (UIP) on HRCT. Patients with UIP experienced worse survival than those with non-UIP. A definite UIP on HRCT and lower baseline performance status have important prognostic implications in patients with IIPs.

Pleural aspergillosis is a rare fungal infection. We herein report a case of pleuritis clinically diagnosed as aspergillosis without apparent Aspergillus lung lesions. A 75-year-old man receiving immunosuppressive therapy due to microscopic polyangiitis was admitted for treatment of massive pleural effusion. Histology of the parietal pleura revealed septate hyphae. In addition, a hematological marker of Aspergillus indicated Aspergillus pleuritis. The pleural effusion resolved after administration of the voriconazole. The trigger for invasion of Aspergillus into the pleura was thought to be spontaneous pneumothorax, which had occurred five months earlier.

OBJECTIVES: This study aimed to evaluate the remission in rheumatoid arthritis (RA) patients treated with tocilizumab (TCZ), based on prospectively registered data in clinical practice. METHODS: We studied 114 consecutive RA patients treated with TCZ for an average of 3.5 years. Remission was evaluated by using the EULAR criteria and the new ACR/EULAR Boolean-based criteria. RESULTS: Among 114 patients (average age 52.2 years; average disease duration 10.6 years), 76 (67 %) had previously received anti-TNF biologics. Mean baseline DAS28-ESR of 5.4 and improved to 2.4 at 36 months. Overall, DAS28-ESR <2.6 was attained by 66.7 %, while ACR/EULAR remission was attained by 35.1 %. ACR/EULAR remission rate was significantly higher in the patients who were biologics-naïve and had good response at the first month. Among 23 patients who completed the treatment for 3 years and had ACR/EULAR remission at 1 year, 15 (65 %) remained in the remission and 16 (70 %) had a DAS28-ESR <2.6 at the final follow-up. The retention rate at 36 months was 68.2 %. CONCLUSIONS: In patients with RA, TCZ is highly effective for both biologics-naïve patients and patients previously exposed to biologics, achieving a high remission rate and drug continuation rate (68.2 %) in clinical practice.

BACKGROUND/AIMS: The Japanese National Hospital Organization evidence-based medicine (EBM) Study group for Adverse effects of Corticosteroid therapy (J-NHOSAC) is a Japanese hospital-based cohort study investigating the safety of the initial use of glucocorticoids (GCs) in patients with newly diagnosed autoimmune diseases. Using the J-NHOSAC registry, the purpose of this observational study is to analyse the rates, characteristics and associated risk factors of intracellular infections in patients with newly diagnosed autoimmune diseases who were initially treated with GCs. METHODOLOGY/PRINCIPAL FINDINGS: A total 604 patients with newly diagnosed autoimmune diseases treated with GCs were enrolled in this registry between April 2007 and March 2009. Cox proportional-hazards regression was used to determine independent risk factors for serious intracellular infections with covariates including sex, age, co-morbidity, laboratory data, use of immunosuppressants and dose of GCs. Survival was analysed according to the Kaplan-Meier method and was assessed by the log-rank test. There were 127 serious infections, including 43 intracellular infections, during 1105.8 patient-years of follow-up. The 43 serious intracellular infections resulted in 8 deaths. After adjustment for covariates, diabetes (Odds ratio [OR]: 2.5, 95% confidence interval [95% CI] 1.1-5.9), lymphocytopenia (â¦1000/µl, OR: 2.5, 95% CI 1.2-5.2) and use of high-dose (â§30 mg/day) GCs (OR: 2.4, 95% CI 1.1-5.3) increased the risk of intracellular infections. Survival curves showed lower intracellular infection-free survival rate in patients with diabetes, lymphocytopaenia and high-dose GCs treatments. CONCLUSIONS/SIGNIFICANCE: Patients with newly diagnosed autoimmune diseases were at high risk of developing intracellular infection during initial treatment with GCs. Our findings provide background data on the risk of intracellular infections of patients with autoimmune diseases. Clinicians showed remain vigilant for intracellular infections in patients with autoimmune diseases who are treated with GCs.

Glucocorticoid (GC) therapy is associated with the risk of life-threatening adverse events in patients with autoimmune disease. To determine accurately the incidence and predictors of GC-related adverse events during initial GC treatment, we conducted a cohort study. Patients with autoimmune disease who were initially treated with GCs in Japan National Hospital Organization (NHO) hospitals were enrolled. Cox proportional hazard regression was used to determine the independent risks for GC-related serious adverse events and mortality. Survival was analyzed according to the Kaplan-Meier method and was assessed with the log-rank test.The 604 patients had a total follow-up of 1105.8 person-years (mean, 1.9 year per patient). One hundred thirty-six patients had at least 1 infection with objective confirmation, and 71 patients had serious infections. Twenty-two cardiovascular events, 55 cases of diabetes, 30 fractures, 23 steroid psychosis events, and 4 avascular bone necrosis events occurred during the follow-up period. The incidence of serious infections was 114.8 (95% confidence interval, 95.7-136.6) per 1000 person-years. After adjustment for covariates, the following independent risk factors for serious infection were found: elderly age (hazard ratio [HR], 1.25/10-yr age increment; p = 0.016), presence of interstitial lung disease (HR, 2.01; p = 0.011), high-dose GC use (≥29.9 mg/d) (HR, 1.71; p = 0.047), and low performance status (Karnofsky score, HR, 0.98/1-score increment; p = 0.002). During the follow-up period, 73 patients died, 35 of whom died of infection. Similarly, elderly age, the presence of interstitial lung disease, and high-dose GC use were found to be significant independent risk factors for mortality. The incidence of serious and life-threatening infection was higher in patients with autoimmune disease who were initially treated with GCs. Although the primary diseases are important confounding factors, elderly age, male sex, the presence of interstitial lung diseases, high-dose GCs, and low performance status were shown to be risk factors for serious infection and mortality.
RESUMEN
OBJECTIVES: This study aimed to evaluate the remission in rheumatoid arthritis (RA) patients treated with tocilizumab (TCZ), based on prospectively registered data in clinical practice. METHODS: We studied 114 consecutive RA patients treated with TCZ for an average of 3.5 years. Remission was evaluated by using the EULAR criteria and the new ACR/EULAR Boolean-based criteria. RESULTS: Among 114 patients (average age 52.2 years; average disease duration 10.6 years), 76 (67 %) had previously received anti-TNF biologics. Mean baseline DAS28-ESR of 5.4 and improved to 2.4 at 36 months. Overall, DAS28-ESR <2.6 was attained by 66.7 %, while ACR/EULAR remission was attained by 35.1 %. ACR/EULAR remission rate was significantly higher in the patients who were biologics-naïve and had good response at the first month. Among 23 patients who completed the treatment for 3 years and had ACR/EULAR remission at 1 year, 15 (65 %) remained in the remission and 16 (70 %) had a DAS28-ESR <2.6 at the final follow-up. The retention rate at 36 months was 68.2 %. CONCLUSIONS: In patients with RA, TCZ is highly effective for both biologics-naïve patients and patients previously exposed to biologics, achieving a high remission rate and drug continuation rate (68.2 %) in clinical practice.
