Association between use of antipyretics and antibody titers after two doses of the BNT162b2 SARS-CoV-2 vaccine in adolescents and young adults with underlying diseases.

There are few reports on the association between antipyretic use and antibody titers in adolescents and young adults following SARS-CoV-2 vaccination. Multivariable linear regression analyses were performed to examine the association between antipyretic use and antibody titers. The use of antipyretics was not associated with antibody titers (ß coefficient [95% CI] = -0.107 [-0.438 to 0.224]).

Safety and antibody response of the BNT162b2 SARS-CoV-2 vaccine in children aged 5-11 years with underlying diseases: A prospective observational study.

BACKGROUND: Data on the safety and antibody response of the BNT162b2 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccine in children aged 5-11 years with underlying diseases are limited. Thus, our study aimed to address this gap. METHODS: This prospective observational study investigated the antibody titers for SARS-CoV-2 spike protein receptor-binding domain (S-IgG) and nucleocapsid protein (N-IgG) in patients aged 5-11 years with chronic underlying diseases following two doses of BNT162b2. Additionally, a questionnaire was used to assess adverse events (AEs) arising within 7 days after each dose. Data on severe AEs arising within 28 days after each dose were extracted from the patients' electronic medical records. RESULTS: Among 122 patients, 24.6% (30/122) were immunocompromised. Furthermore, 79 patients experienced at least one AE following vaccination, but all recovered without sequelae, including one severe case after the first dose. The seropositivity rate after the second dose was 99.1% (116/117). Excluding 19 N-IgG-positive patients, the geometric mean antibody titer (GMT) was significantly higher in immunocompetent patients than in immunocompromised patients (1496 U/mL [95% confidence interval 1199-1862] vs. 472 U/mL [200-1119], p = 0.035). Additionally, the GMT of S-IgG was higher in N-IgG-positive patients than in N-IgG-negative patients (8203 [5847-11482] U/mL vs. 1127 [855-1486] U/mL, p < 0.001). CONCLUSIONS: BNT162b2 is acceptably safe and immunogenic for children aged 5-11 years with underlying diseases. Although seroconversion was satisfactory in immunocompromised patients, the titers were lower than in immunocompetent patients.

Pharmacogenetic implementation for CYP2C19 and pharmacokinetics of voriconazole in children with malignancy or inborn errors of immunity.

BACKGROUND: Voriconazole pharmacokinetics (PK) are known to be affected by genetic polymorphisms of drug-metabolizing enzymes such as CYP2C19; however, such information is limited for the pediatric population. The primary aim of this study is to establish a voriconazole PK model incorporating CYP2C19 phenotypes in Japanese children with malignancy or inborn errors of immunity. METHODS: CYP2C19 genotypes were assessed by whole-genome genotyping and defined as follows: *17/*17: ultrarapid metabolizer (URM), *1/*17: rapid metabolizer (RM), *1/*1:normal metabolizer (NM), *1/*2, *1/*3, *2/*17:intermediate metabolizer (IM), and *2/*2, *2/*3, *3/*3: poor metabolizer (PM). Population PK analysis was performed. The voriconazole serum concentration profile was described by a two-compartment model with first-order absorption, mixed linear and nonlinear (Michaelis-Menten) elimination. RESULTS: Voriconazole concentration data were available from 60 patients with a median age of 5.3 years. The phenotypes predicted from CYP2C19 genotypes were RM in 1 (2 %), NM in 21 (35 %) patients, IM in 27 (45 %) patients, and PM in 11 (18 %) patients. Underlying diseases included 38 (63%) patients with hematological malignancy and 18 (30 %) patients with inborn errors of immunity. Among the CYP2C19 phenotypes, PM was predicted to show complete inhibition (the degree of Vmax inhibition [Vmax, inh] = 100 %; Vmax = 0). The estimated parameters of Vmax,inh were +0.8 higher in patients with gamma-glutamyl transpeptidase (γ-GTP) Grade 2 or higher and +2.7 higher when C-reactive protein (CRP) levels were 2.0 mg/dL or higher. CONCLUSION: CYP2C19 genetic polymorphisms, γ-GTP, and CRP affect Vmax,inh of voriconazole in children with malignancy or inborn errors of immunity.

Trends in Treatment for Patients with Late-onset Rheumatoid Arthritis in Japan: Data from the NinJa Study.

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.

Challenges Nurses Face in Providing Care for Patients with Juvenile Idiopathic Arthritis.

OBJECTIVES: This study aimed at identifying challenges nurses face in caring for patients with juvenile idiopathic arthritis (JIA) in Japan. METHODS: Nurses certified by the Japan Rheumatism Foundation were asked to describe their challenges with caring for JIA patients. Data was analyzed using qualitative content analysis. RESULTS: Responses were collected from 89 participants. 58 issues were identified from 40 participants with experience caring for JIA patients. Sixteen categories emerged, grouped into five challenges: communication, understanding, expertise, system, and collaboration. Care for JIA patients included different challenges from adult patients with rheumatoid arthritis, such as complicated patient-parent relationships, inadequate patient independence and insufficient patient information. Moreover, 76 issues from 49 participants with no experience were identified. Seven categories emerged, grouped into two challenges: expertise and opportunity. Issues included in expertise between both groups were similar. Even with no experience caring for JIA patients, nurses recognized the importance of acquiring knowledge. CONCLUSION: This is the first study in Japan regarding the difficulties nurses face in caring for JIA patients. Multidisciplinary team care and a comprehensive understanding of the patient journey, including relationships with guardians, acquaintances, and healthcare providers, is crucial to improve treatment outcome and overall patient quality of life.

Consensus statement on the management of late-onset rheumatoid arthritis.

OBJECTIVES: Late-onset rheumatoid arthritis (LORA), which has been increasing in recent years, lacks evidence for initial treatment. Japanese rheumatology experts recognized this gap and addressed it by developing consensus statements on the first clinical application of LORA. METHODS: These statements were created following an introductory discussion about treatment fundamentals, which included a review of existing literature and cohort data. The steering committee created a draft, which was refined using a modified Delphi method that involved panel members reaching a consensus. The panel made decisions based on input from geriatric experts, clinical epidemiologists, guideline developers, patient groups, and the LORA Research Subcommittee of the Japan College of Rheumatology. RESULTS: The consensus identified four established facts, three basic approaches, and six expert opinions for managing LORA. Methotrexate was recommended as the primary treatment, with molecular-targeted agents being considered if treatment goals cannot be achieved. An emphasis was placed on assessing the lives of older patients due to challenges in risk management and methotrexate accessibility caused by comorbidities or cognitive decline. CONCLUSIONS: The experts substantiated and refined 13 statements for the initial treatment of LORA. To validate these claims, the next is to conduct a registry study focusing on new LORA cases.

Monogenic inflammatory bowel disease with STXBP2 mutations is not resolved by hematopoietic stem cell transplantation but can be alleviated via immunosuppressive drug therapy.

STXBP2, encoding syntaxin-binding protein 2, is involved in intracellular organelle trafficking and is associated with familial hemophagocytic lymphohistiocytosis type 5. Although STXBP2 mutations reportedly cause monogenic inflammatory bowel disease, the clinical course and underlying pathogenic mechanisms remain unclear. We identified a novel mutation in STXBP2 [c.1197delC, p.Ala400fs] in a boy with congenital intractable diarrhea and hemophagocytic lymphohistiocytosis (HLH). HLH was treated with intravenous prednisolone, cyclosporine, and dexamethasone palmitate. Hematopoietic stem cell transplantation (HSCT) along with prophylaxis for graft-versus-host-disease was performed at 5 months of age. Additionally, colonoscopies done before and after HSCT showed mild colitis with cryptitis. The patient showed elevated fecal calprotectin levels and persistent diarrhea even after HSCT and required partial parenteral nutrition. While anti-inflammatory treatment reduced diarrhea, it was not completely normalized even after HSCT, suggesting that the pathogenesis of inflammatory bowel disease associated with STXBP2 mutations involves both hyperinflammation and functional epithelial barrier defects.

Risk factors for severity in seasonal respiratory viral infections and how they guide management in hematopoietic cell transplant recipients.

PURPOSE OF REVIEW: Seasonal respiratory virus infections (RVIs) often progress to severe diseases in hematopoietic cell transplant (HCT) recipients. This review summarizes the current evidence on risk factors for the severity of RVIs in this high-risk population and provides clinical management. RECENT FINDINGS: The likelihood of the respiratory viral disease progression depends on the immune status of the host and the type of virus. Conventional host factors, such as the immunodeficiency scoring index and the severe immunodeficiency criteria, have been utilized to estimate the risk of progression to severe disease, including mortality. Recent reports have suggested nonconventional risk factors, such as hyperglycemia, hypoalbuminemia, prior use of antibiotics with broad anaerobic activity, posttransplant cyclophosphamide, and pulmonary impairment after RVIs. Identifying novel and modifiable risk factors is important with the advances of novel therapeutic and preventive interventions for RVIs. SUMMARY: Validation of recently identified risk factors for severe RVIs in HCT recipients is required. The development of innovative interventions along with appropriate risk stratification is critical to improve outcomes in this vulnerable population.

Safety of and antibody response to the BNT162b2 COVID-19 vaccine in adolescents and young adults with underlying disease.

BACKGROUND: Data are limited regarding the safety of and antibody response to the BNT162b2 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) messenger ribonucleic acid vaccine in adolescents and young adults with underlying disease. METHODS: This prospective observational study enrolled patients age 12-25 years with chronic underlying disease who received 2 doses of BNT162b2. A 18-item questionnaire was used to assess adverse events within 7 days post-vaccination, and data regarding severe adverse events were collected from electronic medical records. An antibody titer for the receptor-binding domain of the spike protein in SARS-CoV-2 was used to assess antibody response after the second vaccine dose. RESULTS: Study participants were 429 patients (241 [56.2%] age 12-15 years; 188 [43.8%] age 16-25 years). The most common underlying diseases were genetic or chromosomal abnormalities and/or congenital anomalies, followed by endocrine or metabolic diseases; 32% of participants were immunocompromised. Severe adverse events were observed after the second dose in 1 (0.4%) patient age 12-15 years and in 2 (1.1%) patients age 16-25 years; all patients recovered. Seropositivity after the second vaccine dose was 99.0%. The geometric mean antibody titer was higher in patients age 12-15 years versus 16-25 years (1603.3 [1321.8-1944.7] U/mL vs. 949.4 [744.2-1211.0] U/mL). Compared with immunocompetent patients, immunocompromised patients had a lower antibody titer (2106.8 [1917.5-2314.7] U/mL vs. 467.9 [324.4-674.8] U/mL). CONCLUSIONS: Vaccination with BNT162b2 was acceptably safe and immunogenic for adolescents and young adults with underlying disease.

Challenges faced by nurses engaged in rheumatology care in Japan.

OBJECTIVES: This study aimed to identify the challenges faced by nurses engaged in rheumatology care in Japan. METHODS: We conducted a questionnaire survey of nurses in Japan in 2020 on challenges experienced in rheumatology care. The participants were nurses certified by the Japan Rheumatism Foundation. Participants' answers were coded and categorized based on relevant phrases and words. Content analysis was performed on the findings. RESULTS: Responses were collected from 162 participants, and a total of 228 issues were identified. Eighteen categories with 56 subcategories emerged from the data analysis, which were grouped into five types of challenges: (1) communication, (2) understanding, (3) expertise, (4) system, and (5) collaboration. In particular, the results highlighted deficiencies in needs-based multidisciplinary team care. CONCLUSION: This study elucidated issues experienced by rheumatology nurses in clinical settings in Japan. Furthermore, this investigation revealed the necessity of patient-centered multidisciplinary team care, including health professionals, patients, and other relevant individuals. This study provided practical directions to facilitate the implementation of effective care focused on improving patients' quality of life.

Antibodies against Serum Anti-Melanoma Differentiation-Associated Gene 5 in Rheumatoid Arthritis Patients with Chronic Lung Diseases.

Chronic lung diseases (CLD), including interstitial lung disease (ILD) and airway diseases (ADs), are common complications of rheumatoid arthritis (RA). Rheumatoid factor (RF) and anti-citrullinated peptide antibodies are reported to be associated with CLD in RA patients. The presence of anti-melanoma differentiation-associated gene 5 (MDA5) antibodies (Abs) is associated with clinically amyopathic dermatomyositis developing into rapidly progressive ILD. However, few studies on anti-MDA5 Abs in RA have been published. Here, we analyzed the association of anti-MDA5 Abs with CLD complications in RA. Anti-MDA5 Abs were quantified in sera from RA patients with or without CLD. Anti-MDA5 Ab levels were higher in RA patients with ADs than without (mean ± SDM, 4.4 ± 2.4 vs. 4.0 ± 4.2, p = 0.0001). AUC values of anti-MDA5 Ab and RF ROC curves were similar in RA patients with or without CLD (0.578, 95%CI 0.530-0.627 and 0.579, 95%CI 0.530-0.627, respectively, p = 0.9411). Multiple logistic regression analysis of anti-MDA5 Abs and clinical characteristics yielded an MDA5-index with a higher AUC value than anti-MDA5 Ab alone (0.694, 95%CI 0.648-0.740, p = 5.08 × 10-5). Anti-MDA5 Abs were associated with ADs in RA patients and could represent a biomarker for CLD, similar to RF. The involvement of anti-MDA5 Abs in the pathogenesis of ADs in RA is proposed.

[A Case of Esophageal Cancer with Consciousness Disorder Due to Hyperammonemia during FP Treatment].

Hyperammonemia induced by 5-fluorouracil(5-FU)is known as a rare adverse event, but there are few reports of hyperammonemia occurring during FP(5-FU plus CDDP)treatment for esophageal cancer. We report a case of esophageal cancer with consciousness disorder due to hyperammonemia during FP treatment with an examination of some of the relevant literature. The patient was a man of approximately 70 years of age who was received FP treatment. He showed consciousness disorder on day 4. A blood test showed hyperammonemia(427µg/dL), which was considered to be the cause of his consciousness disorder. He was treated with branched chain amino acid infusion, lactulose and kanamycin and made a full recovery. An operation for esophageal cancer was performed after 3 months and he is currently followed up without recurrence. Hyperammonemia should be considered as a differential diagnosis of consciousness disorder during chemotherapy including 5-FU.

Branched chain amino acids in the treatment of polymyositis and dermatomyositis: a phase II/III, multi-centre, randomized controlled trial.

OBJECTIVES: To assess the efficacy and safety of branched chain amino acids (BCAAs) in the treatment of PM/DM prior to official approval of their use in Japan. METHODS: Treatment naïve adults with PM/DM were enrolled in a randomized, double-blind trial to receive either TK-98 (drug name of BCAAs) or placebo in addition to conventional treatment. After 12 weeks, patients with an average manual muscle test (MMT) score <9.5 were enrolled in an open label extension study for a further 12 weeks. The primary endpoint was the change of the MMT score at 12 weeks. The secondary endpoints were the clinical response and the change of functional index (FI). RESULTS: Forty-seven patients were randomized either to the TK-98 (n = 24) or placebo (n = 23) group. The changes of MMT scores at 12 weeks were 0.70 (0.19) [mean (s.e.m.)] and 0.69 (0.18), respectively (P = 0.98). Thirteen patients from the TK-98 group and 12 from the placebo group were enrolled in the extension study. The MMT scores in both groups improved similarly. The increase of the FI scores of the shoulder flexion at 12 weeks was significantly greater in the TK-98 group [27.9 (5.67) vs 12.8 (5.67) for the right shoulder flexion, and 27.0 (5.44) vs 13.4 (5.95) for the left shoulder; P < 0.05]. Frequencies of adverse events up to 12 weeks were similar. CONCLUSION: BCAAs showed no effect on the improvement of the muscle strength evaluated by MMT and the clinical response. However, they were partly effective for improving dynamic repetitive muscle functions. TRIAL REGISTRATION: UMIN-CTR Clinical Trial, https://center6.umin.ac.jp/, UMIN000016233.

Serum rheumatoid factor IgA, anti-citrullinated peptide antibodies with secretory components, and anti-carbamylated protein antibodies associate with interstitial lung disease in rheumatoid arthritis.

OBJECTIVE: Rheumatoid arthritis (RA) is often complicated with chronic lung diseases (CLD), including interstitial lung disease (ILD) and airway disease, which occur as extra-articular manifestations. CLD in RA have been associated with the production of rheumatoid factor (RF), anti-citrullinated peptide antibody (ACPA), or anti-carbamylated protein (CarP) antibody. However, few validation studies have been performed thus far. In the present study, we investigated the association of RF, ACPA, and anti-CarP antibodies with RA complicated with CLD. METHODS: Sera from RA patients with or without CLD were collected. The levels of serum RF, RF immunoglobulin A (IgA), ACPA IgG, ACPA IgA, and ACPA secretory component (SC) were measured using enzyme-linked immunosorbent assay. RESULTS: The comparison of RA patients with and without CLD showed that RF IgA was associated with ILD (mean ± standard deviation: 206.6 ± 400.5 vs. 95.0 ± 523.1 U/ml, respectively, P = 1.13 × 10- 8), particularly usual interstitial pneumonia (UIP) (263.5 ± 502.0 U/ml, P = 1.00 × 10- 7). ACPA SC was associated with RA complicated with ILD (mean ± standard deviation: 8.6 ± 25.1 vs. 2.3 ± 3.4 U/ml, respectively, P = 0.0003), particularly nonspecific interstitial pneumonia (NSIP) (10.7 ± 31.5 U/ml, P = 0.0017). Anti-CarP antibodies were associated with RA complicated with ILD (0.042 ± 0.285 vs. 0.003 ± 0.011 U/ml, respectively, P = 1.04X10- 11). CONCLUSION: RF IgA and ACPA SC in RA were associated with UIP and NSIP, respectively, suggesting different specificities in patients with RA. Anti-CarP antibodies were associated with ILD in RA. These results may help elucidate the different pathogeneses of UIP and NSIP in RA.

Transitioning from paediatric to adult rheumatological healthcare: English summary of the Japanese Transition Support Guide.

Issues related to transitioning from paediatric to adult healthcare are currently receiving international attention. In Japan, 1000 patients with childhood-onset chronic rheumatological diseases reach adulthood every year and require transition from care by paediatric to care by adult rheumatologists. Here, we propose a guide for the latter, wherein the adult caregiver poses the clinical questions about transitional support that they need to have answered, and the paediatric caregiver mainly compiles the plans for the transition. To formulate the guide, we sought comments from both the Japan College of Rheumatology and the Pediatric Rheumatology Association of Japan and obtained their approval. Here, we present the outcome of this consultation in the form of a Guide for Supporting Transitional Care, aiming to provide essential knowledge to physicians in the fields of adult internal medicine and orthopaedics who may be involved in treating patients with rheumatic disease during the transition from paediatric to adult care. The features of transitional support that are common for patients with various different rheumatic diseases are presented in this guide, with the aim of informing policy and strategies to deliver optimal outcomes in transitional care by non-paediatric rheumatologists.

Factors associated with impaired physical function in elderly rheumatoid arthritis patients who had achieved low disease activity.

OBJECTIVE: We aimed to investigate factors associated with impaired physical function (defined as HAQ Disability Index [HAQ-DI] >0.5) of old-old (aged 75-84) patients with rheumatoid arthritis (RA). METHODS: Data from 15,185 RA patients in the National Database of Rheumatic Disease in Japan were extracted from 2017 to 2018. We enrolled 3,708 patients aged 55-84 in simplified disease activity index (SDAI) ≤11 and Steinbrocker stage I/II. Factors associated with HAQ-DI >0.5 were analyzed by multivariable logistic regression. RESULTS: About half of the old-old patients received methotrexate, which was lower than middle-aged (55-64) and young-old patients (65-74). The proportion of glucocorticoids in the old-old patients was highest among the three groups, and biological disease-modifying anti-rheumatic drugs were similarly used. The prevalence of HAQ-DI >0.5 was significantly higher in old-old patients with low disease activity than in those with remission. The same was true in the middle-aged and young-old patients. Multivariable analysis showed age, higher SDAI, glucocorticoid use, and methotrexate non-use were significantly associated with HAQ-DI >0.5 in the old-old patients. CONCLUSIONS: SDAI remission was an ideal goal for old-old patients in terms of physical function. Glucocorticoids and a low proportion of methotrexate use may influence the physical function of old-old patients.

The Impact of Hybrid Minimally Invasive Esophagectomy with Neck-Abdominal First Approach on the Short- and Long-Term Outcomes for Esophageal Squamous Cell Carcinoma.

BACKGROUND: Currently, there is no consensus for an optimal minimally invasive esophagectomy (MIE) approach. This study aimed to compare hybrid MIE (hMIE) with neck-abdominal first approach to standard open esophagectomy (OE). METHODS: Data from a cohort of 301 patients were retrospectively analyzed. All participants received either hMIE or OE for the treatment of esophageal squamous cell carcinoma at Tokyo Medical and Dental University between January 2003 and December 2013. Analyses included propensity score matching and the Kaplan-Meier statistical method to determine overall survival (OS) and disease-free survival (DFS) of the cohort. RESULTS: After one-to-one propensity score matching, there were 68 patient pairs. The hMIE group had significantly lower incidence of severe postoperative complications (20.1% vs. 7.4%; p = 0.026) and severe respiratory complications (7.4% vs. 0%; p = 0.058) than the OE group. The 5-year oncological outcomes of the two groups were almost equivalent (OS: OE, 55.0%; hMIE, 69.0%; p = 0.063 and DFS: OE, 54.0%; hMIE, 62.0%; p = 0.28). CONCLUSIONS: This study compared hMIE with neck-abdominal first approach to standard OE. The results showed significantly less severe postoperative complications for hMIE with neck-abdominal first approach in comparison with OE, without a compromise in long-term oncological outcomes.

Disease activity, treatment and long-term prognosis of adult juvenile idiopathic arthritis patients compared with rheumatoid arthritis patients.

Objective: To evaluate the difference between adult juvenile idiopathic arthritis (JIA, starting at <16 years) and rheumatoid arthritis (RA).Methods: Data on 128 adult JIA patients were from the National Database of Rheumatic Diseases in Japan (NinJa), 2014, divided into 4 groups by period of disease onset (Group 1: 2000-2013, n = 32; Group 2: 1981-1999, n = 32; Group 3: 1966-1980, n = 31; Group 4: ∼1965, n = 33). Disease activity, treatment and long-term prognosis of adult JIA patients were compared with RA patients matched for sex- and disease duration in each era.Results: In Groups 1 and 2, adult JIA patients had significantly lower clinical disease activity indices (CDAI) (Group 1: adult JIA 1.5 [0.4-6.9]-vs-RA 5.3 [2.5-10.3], p = .001, Group 2: 2.6 [0.6-9.0]-vs-6.9 [3.5-11.0], p = .001, shown as median [quartile range], p-value, respectively), and had higher CDAI remission rates than RA patients (Group 1: 54.8%-vs-28.2%, p = .002, Group 2: 51.7%-vs-17.0%, p < .001). More adult JIA than RA patients in Group 1 used biologics (62.5%-vs-24.7%, p < .001). However, there were no adult JIA-vs-RA differences in joint destruction and physical function in any group.Conclusions: Adult rheumatologists must recognize that adult JIA patients are different from RA patients even when disease duration is the same.

Related factors, increased mortality and causes of death in patients with rheumatoid arthritis-associated interstitial lung disease.

Objectives: Interstitial lung disease (ILD) is a life-threatening extra-articular manifestation of rheumatoid arthritis (RA). We aimed to clarify the relationship between chronic ILD with a pattern of usual interstitial pneumonia (UIP) or non-UIP and mortality in RA patients.Methods: We retrospectively surveyed information of consecutive RA patients who visited our hospital from 2009 to 2014. The relationship between their mortality and chronic ILD (UIP or non-UIP) detected by high-resolution computed tomography was examined.Results: Of 2702 patients enrolled, 261 (9.7%) had chronic ILD and among these 120 had a UIP pattern. At the onset of RA, the prevalence of chronic ILD was 6%. Patients with chronic ILD had a higher mortality than those without. The most frequent cause of death was pneumonia including acute exacerbation (AE) of chronic ILD. Lung cancer death was frequently identified in deceased patients with chronic ILD with a UIP pattern compared with the other decedents (p=.062). The estimated mortality of lung cancer in patients with chronic ILD with a UIP pattern was five times higher than the general population.Conclusion: RA patients with ILD with a UIP pattern have a high mortality rate and are prone to die of AE or lung cancer.

The development of quality indicators for systemic lupus erythematosus using electronic health data: A modified RAND appropriateness method.

Objective: Quality indicators (QIs) are tools that standardize evaluations in terms of the minimum acceptable quality of care, presumably contributing for the better management of patients with systemic lupus erythematosus (SLE). This study aimed to develop QIs for SLE using electronic health data.Methods: The modified RAND/UCLA Appropriateness Method was used to develop the QIs. First, a literature review was conducted. Second, the candidate QI items that were available to be evaluated using the electronic health data were extracted. Third, the appropriateness of the items was assessed via rating rounds and panelists' discussions.Results: We found 3621 articles in the initial search. Finally, 34 studies were reviewed, from which 17 potential indicators were extracted as candidate QIs. Twelve indicators were selected as the final QI set through the process of appropriateness. The median appropriateness of these 12 indicators was at least 7.5, and all of them were without disagreement. The QI included assessment of disease activity, treatment of SLE, drug toxicity monitoring, treatment of glucocorticoid complications, and assessment of SLE complications.Conclusion: We formulated 12 QIs for the assessment of patients with SLE based on electronic medical data. Our QI set would be a practical tool as a quality measure.
