RESUMO
OBJECTIVES: A quality indicator for the treatment of systemic lupus erythematosus during pregnancy and childbirth that is useful for sharing standard treatment policies has not yet been developed. This study aimed to develop a quality indicator for systemic lupus erythematosus associated with pregnancy and childbirth. METHODS: To identify candidate quality indicators, we conducted a systematic literature review on the development of quality indicators for systemic lupus erythematosus related to pregnancy and childbirth and on clinical practice guidelines. Candidate quality indicator items were extracted from the final selected articles, and a first evaluation, panel meeting, and second evaluation were conducted to determine whether the candidate items were appropriate as quality indicators. Items for which all panel members reached a consensus were designated pregnancy and childbirth-related systemic lupus erythematosus quality indicators. RESULTS: Four articles on systemic lupus erythematosus-quality indicator development and 28 practice guidelines were listed through abstract/text screening. Based on these studies, 52 candidate quality indicators were extracted that were limited to items related to pregnancy and childbirth, and 41 items were selected on which all panel members agreed. CONCLUSION: We developed pregnancy-related systemic lupus erythematosus quality indicators using the RAND/UCLA method and selected 41 items, which could be used clinically.
RESUMO
OBJECTIVES: To investigate if disease activity among elderly RA patients over 75 years has changed over time in the real-world clinical setting. METHODS: Data from an observational multicentre registry of RA patients in Japan were analyzed. The primary outcome was to evaluate the changes in the proportion of very elderly RA patients (over 75 years) who achieved remission and low disease activity, from 2014 to 2021. The secondary outcome was to identify factors associated with remission and low disease activity by comparing demographic and clinical characteristics among the patients who had a study visit within the study period, using multivariate logistic regression. RESULTS: A total of 32 161 patient visits were identified from 2014 to 2021. The proportion of patients over 75 years increased from 16.5% to 26.9%, with biologics and targeted-synthetic disease modifying anti-rheumatic drugs (b/tsDMARDs) usage increasing and glucocorticoids usage decreasing, while conventional-synthetic DMARDs usage remained relatively stable. The proportion of RA patients over 75 years achieving remission and low disease activity significantly increased from 62.2% to 78.2% (p for trend < 0.001). A negative factor associated with achieving remission and low disease activity was glucocorticoid usage, seropositivity, and history of previous b/tsDMARDs use while MTX usage was associated positively, independent of other predictors. CONCLUSIONS: In our cohort, disease activity among very elderly RA patients has improved over time. The study suggests the importance of using a treat-to-target approach in very elderly RA patients to improve clinical outcomes.
RESUMO
This multicenter retrospective study aimed to clarify the prognostic factors for mortality and changes in treatment modalities and disease activities after the onset of Pneumocystis jirovecii pneumonia (PCP) in patients with rheumatoid arthritis (RA). Data regarding the clinical background, treatment modalities, and disease activity indicators of RA at the onset of PCP (baseline), and 6 months and 12 months after treatment were extracted. Of the 37 patients with RA-PCP (median age, 69 years; 73% female), chemical prophylaxis was administered to 8.1%. Six patients died during PCP treatment. The serum C-reactive protein (CRP) levels and the prednisolone (PDN) dose at baseline in the PCP death group were significantly higher than those in the survivor group. Multivariate analysis using a Cox regression model showed that PDN dose at baseline was a predictor of death from PCP in patients with RA. During the 12 months from baseline, the RA disease activity significantly decreased. A high dose of corticosteroids for RA may result in a poor prognosis when PCP is complicated. In the future, preventive administration techniques must be established for patients with RA who need PCP prevention.

The aim of this multi-centre retrospective study was to clarify the prognostic factors for respiratory-related death in patients with interstitial lung disease (ILD) complicated rheumatoid arthritis (RA). Patient background data, treatment regimen, and disease activity indicators of RA and ILD at baseline, 6 months after the diagnosis of ILD, and at the last follow-up visit were extracted. A total of 312 patients with RA-ILD (17 patients who died from respiratory-related causes and 295 survivors) were included. Patients who died from respiratory-related causes had an older median age, a higher proportion of being male, and a higher anti-cyclic citrullinated peptide antibody positivity rate than survivors (p = .0001, .038, and .016, respectively); they also had significantly higher baseline serum levels of Krebs von den Lungen-6 (KL-6) than survivors (p = .013). Patients who died from respiratory-related causes showed significantly greater changes in serum KL-6 levels between the 6-month time point and the last visit [ΔKL-6 (6 months - last)] than survivors (p = .011). Multivariate analysis showed that the ΔKL-6 (6 months - last) corrected by disease duration was a predictor of respiratory-disease-related death in patients with RA-ILD (p < .0001). Long-term increase in serum KL-6 levels is associated with respiratory-disease related death in patients with RA-ILD.

BACKGROUND: Management of infectious complications in pregnant women receiving immunosuppressive therapy for systemic lupus erythematosus (SLE) is important. Maternal infection with cytomegalovirus (CMV) often causes congenital CMV infection in the foetus. Thus far, there are only few reports on congenital CMV infection after maternal reactivation in patients with SLE. We report the first case of congenital CMV infection after maternal primary infection in a patient with SLE. CASE PRESENTATION: A 19-year-old Japanese primigravida with SLE received treatment with prednisolone 3 mg/day and azathioprine 75 mg/day at conception. At 7 weeks of gestation, she suddenly developed fever and had decreased white blood cell and platelet counts and elevated aspartate aminotransferase and alanine aminotransferase levels. These clinical findings led to a diagnosis of SLE exacerbation. The prednisolone dose was increased to 15 mg/day, and hydroxychloroquine (200 mg/day) was administered. Consequently, all clinical findings normalised at 12 weeks. At 19 weeks, foetal ultrasound findings revealed oligohydramnios, brain hypoplasia, ventriculomegaly and hyperechogenic bowel. Maternal serological test results indicated increased CMV-specific IgG and IgM levels, low IgG avidity (26%), and positive CMV antigenemia. The foetus was diagnosed with symptomatic congenital CMV infection transmitted from the maternal primary infection. After counselling about the severe prognosis of the foetus, the mother decided to terminate her pregnancy and underwent artificial abortion at 21 weeks. DISCUSSION: The foetus of a mother with SLE who is receiving immunosuppressive therapy may be at increased risk of transmission and aggravation of congenital CMV infection; thus, preventive management and screening for congenital CMV infection during pregnancy are recommended for such patients. Maternal CMV infection shows clinical findings similar to those of SLE exacerbation, and careful differential diagnosis by maternal serological evaluation and foetal ultrasound scans is required.

Rheumatoid factor (RF) binds to the fragment crystallizable (Fc) portion of immunoglobulin. It could bind to the Fc portion of anti-TNF inhibitors (TNFi) and attenuate the clinical efficacy. We tried to determine whether the therapeutic efficacy of TNFi with Fc might be lower than that of TNFi without Fc in rheumatoid arthritis (RA) patients with high titres of RF. The Kansai Consortium for Well-being of Rheumatic Disease Patients (ANSWER) cohort is an observational multi-center registry of patients with RA in the Kansai district of Japan. RA patients treated with TNFi were included and divided into two groups based on the structural characteristics between TNFi with Fc (infliximab, adalimumab, golimumab, and etanercept) and TNFi without Fc (certolizumab pegol). Patients were classified into 4 groups according to RF titre quartiles. The sequential disease activity score in 28 joints using erythrocyte sedimentation rate (DAS28-ESR) was compared by Mann-Whitney U test between TNFi with and without Fc in each RF titre group. Multiple linear regression analysis was used to analyze the effect of TNFi without Fc for the change of DAS28-ESR adjusted after potential confounders. A total of 705 RA patients were classified into four groups (RF1; RF 0-15.0 IU/mL, RF2; 15.0-55.0, RF3; 55.0-166, RF4; 166-7555). In RF4, RA patients treated with TNFi without Fc had a significantly lower DAS28-ESR than those treated with TNFi with Fc [3.2 (2.3-4.2) vs. 2.7 (2.0-3.0)] after 12 months. This effect of TNFi without Fc for the change of DAS28-ESR after 12 months treatment retained in multivariate analysis in RF4. TNFi without Fc may be more efficacious than TNFi with Fc in RA patients with high RF titres.

OBJECTIVES: We explored rheumatoid arthritis (RA) disease activity before, during, and after pregnancy in patients treated with tight control and investigated the association between disease activity in the postpartum period and those before and during pregnancy. METHODS: We retrospectively reviewed disease activity and medications of 27 patients before pregnancy, at every trimester, and in the postpartum period. RESULTS: Prednisolone was administered to 33% of patients with a median dose of 0 (0-2.5) mg/day and biologic agents was 78% in the third trimester. The median remission rates during all periods were the Disease Activity Score-28-C-reactive Protein assessed with three variables (DAS28-CRP-3) 85%, Simplified Disease Activity Index (SDAI) 55%, and Clinical Disease Activity Index (CDAI) 54%. Although SDAI and CDAI decreased significantly from before pregnancy to the first trimester and increased from the third trimester to the postpartum period, DAS28-CRP-3 did not change during all periods. Although SDAI and CDAI before and during pregnancy were significantly correlated with those in the postpartum period, DAS28-CRP-3 was not. CONCLUSIONS: Tight control before pregnancy suppressed RA disease activity during pregnancy and in the postpartum period. SDAI/CDAI before and during pregnancy were predictive for disease activity in the postpartum period.

OBJECTIVE: The objective of this study was to investigate the role of periodontal pathogens in RA in remission. METHODS: Twenty-one patients with active RA and 70 patients in clinical remission, including 48 patients with synovitis [US power Doppler (USPD)(+) group] and 22 patients without synovitis [USPD(-) group] were clinically assessed by US. CRP, ESR, haemoglobin, MMP-3, RF and ACPA were measured. Antibody titres against four types of periodontal pathogen [Aggregatibacter actinomycetemcomitans, Eikenella corrodens (Ec), Porphyromonas gingivalis and Prevotella intermedia (Pi)] were analysed using ELISA. RESULTS: Musculoskeletal US examination showed that 68.6% of patients with RA in clinical remission exhibited synovitis. CRP, ESR, haemoglobin, MMP-3 and RF levels in both the USPD(+) and USPD(-) groups were clearly lower compared with the RA group in non-remission. The IgG serum antibody titre against Ec in the non-remission RA(+) group was significantly greater than that in the USPD(+) group, and the IgG antibody titre against Pi in the non-remission RA and USPD(+) groups was greater than in the USPD(-) group. CONCLUSION: More than half of RA patients in remission showed persistent synovitis. This synovitis may be associated with periodontal disease-causing Pi. Thus, treating periodontal disease should also be considered in order to achieve more profound remission of RA.

Pulmonary amyloidosis is characterized by extracellular deposition of fibrous protein called amyloid in the lungs and has three subtypes: nodular, diffuse, and tracheobronchial amyloidosis. Pulmonary nodular amyloidosis can mimic other lung diseases including infectious diseases, metastatic lung tumors, sarcoidosis, and pulmonary hyalinizing granuloma. A biopsy of the lesion is essential for a definitive diagnosis. Herein, we report the case of a 66-year-old man who presented for shortness of breath on exertion and was diagnosed with nodular pulmonary amyloidosis on ultrasound-guided percutaneous needle biopsy. A chest X-ray and computed tomography (CT) revealed bilateral slowly growing multiple calcified pulmonary nodules and cavities. Malignancy was suspected based on 18F-fluoro-deoxyglucose (18F-FDG) positron emission tomography/CT (PET/CT) images. An ultrasound-guided percutaneous needle biopsy was performed, and histopathologic examination of the lesion confirmed nodular pulmonary amyloidosis. This case highlights the importance of considering nodular pulmonary amyloidosis in the differential diagnosis of pulmonary nodules with increased uptake of 18F-FDG on PET/CT and the utility of ultrasound-guided needle biopsy in the definitive diagnosis.
RESUMO
Immunoglobulin A vasculitis (IgAV), also known as Henoch-Schönlein purpura (HSP), is a disease that causes inflammation and bleeding in small blood vessels in the skin, joints, intestines, and kidneys. Although various infections and chemicals are known to be triggers, the underlying cause of IgAV remains unknown. Here, we describe a case of an 86-year-old male patient with IgAV that developed after anti-tuberculosis treatment for tuberculous pleurisy. There have been several case reports implicating Mycobacterium tuberculosis and other acid-fast bacterium in the development of IgAV, but only a few case reports implicating anti-tuberculous drugs. This case highlights the importance of recognizing that IgAV can be caused by anti-tuberculous drugs.
RESUMO
AIM: To investigate the association of large joint involvement (LJI) with disease activity and drug retention in patients with rheumatoid arthritis (RA) who started receiving a biological disease-modifying antirheumatic drug or Janus kinase inhibitor. METHODS: Patients with RA from a Japanese multicenter observational registry were enrolled. Our definition of large joints included the shoulder, elbow, hip, knee, and ankle joints. Linear mixed-effects models were used to examine changes in the clinical disease activity index (CDAI) score at Week 24 as the primary outcome, and drug retention rates were compared between patients with and without LJI using Cox proportional hazards models. We examined the potential effect modifications of changes in the CDAI by baseline characteristics. RESULTS: Overall, 2507 treatment courses from 1721 patients were included (LJI, 1744; no LJI, 763). Although LJI was associated with significantly higher changes in CDAI from baseline at Week 24 (difference in change in CDAI: -5.84 [-6.65 to -5.03], p < .001), CDAI was significantly higher in patients with LJI over time. Retention rates were similar in both groups. The association of LJI with changes in disease activity was more prominent in patients with a short disease duration, negative anti-citrullinated peptide antibodies, and interleukin-6 receptor inhibitor (IL-6Ri) use. CONCLUSION: Although LJI was associated with a greater reduction in disease activity from baseline, higher disease activity at baseline was not offset over time in patients with LJI, demonstrating that LJI is an unfavorable predictor. An early treat-to-target strategy using an IL-6Ri may be beneficial for patients with LJI.

The diagnostic criteria of aspiration pneumonia have not been established, and it remains an underdiagnosed entity. Diagnosis and cause investigation is essential in improving the management of aspiration pneumonia. The Japanese Respiratory Society Guidelines for the Management of Pneumonia in Adults (JRS Guidelines) show a list of risk factors for aspiration pneumonia. We developed an algorithm to aid physicians in evaluating these possible underlying factors and guide their management with a focus on aspiration pneumonia. The algorithm was developed based on the JRS Guidelines. The algorithm suggested dysphagia screening, pneumococcal and influenza vaccination, and other preventative measures for pneumonia. The algorithm was implemented in the acute setting of a general hospital among older patients admitted with pneumonia. Their outcomes were compared with a historical control group constituting similar patients from the previous year. Forty patients with pneumonia were assessed with the algorithm group, and 44 patients were included in the control group. In the algorithm group, significantly more cases (95.0% vs. 15.9%, p < 0.01) underwent early screening for a swallowing disorder. Two patients in the algorithm group were diagnosed with a new condition causing aspiration pneumonia, as opposed to none in the control group. Drugs with a potential risk for aspiration were identified and discontinued in 27.5% of the patients in the algorithm group and 4.5% in the control group. In conclusion, an aspiration pneumonia cause investigation algorithm translating the JRS guideline approach into practice enhanced the rate of swallow screening and preventative measures for aspiration.

Spontaneous pneumothorax occurs predominantly in young males and older adults, often as a secondary condition, and can be refractory and fatal. This study aimed to investigate the mortality and prognostic factors for pneumothorax in older patients. We retrospectively cohort studied patients with pneumothorax aged ≥65 years who visited our department from October 2012 to January 2019. Data on sex, age, medical history, smoking history, underlying lung disease, treatment, and prognosis were extracted from medical records. Cox proportional hazards regression analysis was used to investigate pneumothorax mortality and prognostic factors. In total, 239 patients were included. Among them, 36 (15%) died during hospitalization. Respiratory disease was the direct cause of death in 30 patients (83.3%), and 211 (88.3%) patients had underlying lung disease. The incidence of pneumonia in our hospital was 22.6% (54 cases). On admission, the mortality rate was 33% (18/54) in patients with concomitant pneumonia; univariate analysis showed significant differences in the Charlson Comorbidity Index (CCI), activities of daily living (ADL), and concomitant pneumonia. In the Cox proportional hazards analysis of ADL (p = 0.09), CCI (p = 0.05), and concomitant pneumonia on admission (p = 0.02), concomitant pneumonia on admission was found to be an independent predictor of in-hospital mortality. This study suggests that concomitant pneumonia at admission may be a mortality risk factor for pneumothorax.

OBJECTIVES: This multicentre retrospective study in Japan aimed to assess the retention of biological disease-modifying antirheumatic drugs and Janus kinase inhibitors (JAKi), and to clarify the factors affecting their retention in a real-world cohort of patients with rheumatoid arthritis. METHODS: The study included 6666 treatment courses (bDMARD-naïve or JAKi-naïve cases, 55.4%; tumour necrosis factor inhibitors (TNFi) = 3577; anti-interleukin-6 receptor antibodies (aIL-6R) = 1497; cytotoxic T lymphocyte-associated antigen-4-Ig (CTLA4-Ig) = 1139; JAKi=453 cases). The reasons for discontinuation were divided into four categories (ineffectiveness, toxic adverse events, non-toxic reasons and remission); multivariate Cox proportional hazards modelling by potential confounders was used to analyse the HRs of treatment discontinuation. RESULTS: TNFi (HR=1.93, 95% CI: 1.69 to 2.19), CTLA4-Ig (HR=1.42, 95% CI: 1.20 to 1.67) and JAKi (HR=1.29, 95% CI: 1.03 to 1.63) showed a higher discontinuation rate due to ineffectiveness than aIL-6R. TNFi (HR=1.28, 95% CI: 1.05 to 1.56) and aIL-6R (HR=1.27, 95% CI: 1.03 to 1.57) showed a higher discontinuation rate due to toxic adverse events than CTLA4-Ig. Concomitant use of oral glucocorticoids (GCs) at baseline was associated with higher discontinuation rate due to ineffectiveness in TNFi (HR=1.24, 95% CI: 1.09 to 1.41), as well as toxic adverse events in JAKi (HR=2.30, 95% CI: 1.23 to 4.28) and TNFi (HR=1.29, 95%CI: 1.07 to 1.55). CONCLUSIONS: TNFi (HR=1.52, 95% CI: 1.37 to 1.68) and CTLA4-Ig (HR=1.14, 95% CI: 1.00 to 1.30) showed a higher overall drug discontinuation rate, excluding non-toxicity and remission, than aIL-6R.

We report a case of an isolated congenital interruption of the right interlobar pulmonary artery with unilateral interstitial lung abnormality. 3D-CT with enhancement showed absent right interlobar pulmonary artery without any other abnormalities of the pulmonary artery and an enlarged inferior phrenic artery. High-resolution CT demonstrated ground-glass opacities, reticular changes, and small cysts in the right middle and lower lobes, which were compatible with interstitial lung abnormality. The patient was diagnosed with an isolated congenital interruption of the right interlobar pulmonary artery since chronic pulmonary thromboembolism, structural heart disease, systemic congenital disease, and systemic vasculitis were ruled out.
RESUMO
BACKGROUND: With the abundance of CT scanners in Japan, doctors can easily order CT scans to diagnose pneumonia. The Japanese Respiratory Society (JRS) guidelines uniquely recommend conditions for which additional CT scans should be considered at the time of diagnosis of pneumonia, a feature not found in other guidelines. In this study, we aimed to evaluate the usefulness of the recommendations in a bid to reduce the number of unnecessary CT examinations. METHODS: We retrospectively reviewed the electronic medical records of consecutive patients with pneumonia hospitalized between April 2016 and March 2017 to extract patients' backgrounds and clinical courses. Conformity with the JRS guideline recommendations was also examined. In the patients who did not meet the recommendations, we investigated the proportion of them for whom an additional CT scan influenced the clinical decisions. Finally, we evaluated whether there was a difference in hospital stay depending on the additional chest CT at the time of admission. RESULTS: We included 363 hospitalized patients with pneumonia. Chest CT scan was performed in 306 patients (84.3%), of whom 186 (60.8%) did not meet the JRS guideline recommendations. Chest CT revealed findings requiring a change in treatment strategy in only 14 (7.5%) of the 186 patients. Among the 240 patients (66.1%) who did not meet the recommendations, no statistically significant difference was observed in the hospital stay or mortality between patients with and without CT scans. CONCLUSIONS: Adherence to the JRS guideline recommendations may reduce the excessive use of CT scans in the diagnosis of pneumonia.

BACKGROUND: This study aimed to clarify predictors of preterm birth in pregnancy of women with systemic lupus erythematosus (SLE). We investigated the predictors of preterm birth before pregnancy from the perspective of the importance of preconception care. METHODS: We analysed fetal outcomes of 108 pregnancies in 74 SLE patients in a retrospective study. We compared pre-pregnancy clinical characteristics and disease activity in these women between the preterm birth and full-term birth groups to select predictive factors for preterm birth before pregnancy. RESULTS: Eighty-three of 108 pregnancies resulted in live births, of which 27 (25.0%) were preterm births. Pre-pregnancy serum complement 3 (C3) level was significantly lower in the preterm birth group (77.0 mg/dl) than the full-term birth group (87.5 mg/dl) (P = 0.029). Multivariate analysis identified history of lupus nephritis (odds ratio: 5.734, 95% CI 1.568-21.010, P = 0.008) and low C3 level (< 85 mg/dl) at pre-pregnancy (odds ratio 4.498, 95% CI 1.296-15.616, P = 0.018) as risk factors for preterm birth. The greater the number of these risk factors, the higher was the preterm birth rate (P = 0.0007). In the case of SLEDAI score ≤ 4, the preterm birth rate was higher in the pre-pregnancy low C3 group (< 85 mg/dl) (42.1%) than in the high C3 group (C3 ≥ 85 mg/dl) (14.7%) (P = 0.018). CONCLUSION: For patients with a history of LN, treatment management focusing on pre-pregnancy serum complement levels is very important.

Large-cell carcinoma (LCC) of the lung is defined as an undifferentiated non-small cell lung cancer (NSCLC) and accounts for approximately 7.5% of lung cancers. Immune checkpoint inhibitors (ICIs) may be effective for LCC, but there has been no firm evidence due to its low frequency. We herein report an 80-year-old woman with LCC of the lung who was successfully treated with pembrolizumab but developed sclerosing cholangitis as an immune-related adverse event. This case highlights the efficacy of ICIs for LCC as well as the importance of the immediate and detailed management of ICI-related sclerosing cholangitis.

RESUMO
BACKGROUND: Serum lactate level can predict clinical outcomes in some critical cases. In the clinical setting, we noted that patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR) and with poor serum lactate improvement often do not recover from cardiopulmonary arrest. Therefore, we investigated the association between lactate clearance and in-hospital mortality in cardiac arrest patients undergoing ECPR. METHODS: Serum lactate levels were measured on admission and every hour after starting ECPR. Lactate clearance [(lactate at first measurement - lactate 6 h after)/lactate at first measurement × 100] was calculated 6 h after first serum lactate measurement. All patients who underwent ECPR were registered retrospectively using opt-out in our outpatient's segment. RESULT: In this retrospective study, 64 cases were evaluated, and they were classified into two groups according to lactate clearance: high-clearance group, > 65%; low-clearance group, ≤ 65%. Surviving discharge rate of high-clearance group (12 cases, 63%) is significantly higher than that of low-clearance group (11 cases, 24%) (p < 0.01). Considering other confounders, lactate clearance was an independent predictor for in-hospital mortality (odds ratio, 7.10; 95% confidence interval, 1.71-29.5; p < 0.01). Both net reclassification improvement (0.64, p < 0.01) and integrated reclassification improvement (0.12, p < 0.01) show that adding lactate clearance on established risk factors improved the predictability of in-hospital mortality. CONCLUSION: In our study, lactate clearance calculated through arterial blood gas analysis 6 h after ECPR was one of the most important predictors of in-hospital mortality in patients treated with ECPR after cardiac arrest.
