Comparison of retention of biologics in Japanese patients with elderly-onset rheumatoid arthritis-the ANSWER cohort study.

OBJECTIVES: This multicentre, retrospective study aimed to compare retention and reasons for discontinuation between Janus kinase inhibitors (JAKi) and biologic disease-modifying antirheumatic drugs in patients with elderly-onset rheumatoid arthritis (EORA). METHODS: Patients with RA enrolled in a Japanese multicentre observational registry between 2015 and 2022 were included. EORA was defined as RA with onset at 60 or over. To adjust confounding factors by indication for initiation of tumor necrosis factor inhibitors (TNFi), interleukin-6 inhibitors (IL-6i), cytotoxic T-lymphocyte associated antigen 4 immunoglobulin (CTLA4-Ig) blockers, or JAKi, a propensity score based on baseline characteristics was used to compare drug retention. To assess the reasons for discontinuation, retention rates for ineffectiveness, adverse events, and remission were analyzed as secondary outcomes. RESULTS: A total of 572 patients with 835 treatment courses were identified (314 TNFi, 175 IL-6i, 228 CTLA4-Ig, and 118 JAKi). After adjusting for differences in baseline characteristics, drug retention was significantly higher for IL-6i (HR = 0.38, 95%CI = 0.27-0.55, p< 0.01) as compared with TNFi. Discontinuation due to lack of effectiveness was lower with the JAKi (HR = 0.38, 95%CI = 0.22-0.66, p< 0.01) and the IL-6i (HR = 0.29, 95%CI = 0.19-0.46, p< 0.01) as compared with the TNFi although the CTLA4-Ig had a similar HR to TNFi. The adjusted incidence of discontinuation due to adverse event was higher in the JAKi (HR = 2.86, 95%CI = 1.46-5.59, p< 0.01) than the TNFi. CONCLUSIONS: In EORA patients, IL-6i and JAKi had longer retention and less discontinuation due to ineffectiveness than TNFi. The potential risks of JAKi should be approached with an individualized perspective.

Characteristics of patients presenting with concomitant carpal tunnel syndrome at the initial diagnosis with rheumatoid arthritis.

OBJECTIVE: To investigate the clinical characteristics of patients who presented with concomitant carpal tunnel syndrome (CTS) at the initial diagnosis with rheumatoid arthritis (RA). METHODS: We analyzed patients with newly diagnosed RA at a single institution between 2012 and 2021. Patient demographic and laboratory data, the 2010 ACR/EULAR classification criteria, and the duration from the initial visit to RA diagnosis were compared between RA patients with concomitant CTS (RA with CTS group) and those without CTS (RA without CTS group). RESULTS: The study included 235 patients (157 females), of which 11 patients (4.7%) presented with CTS at the initial diagnosis with RA. In the RA with CTS group, the age was significantly higher (P = .033), all patients were female, and anti-cyclic citrullinated peptide antibody (ACPA) was negative, and the duration to RA diagnosis was longer than in the RA without CTS group. Among all RA with CTS patients, ultrasonography showed power Doppler signal-positive tenosynovitis in the carpal tunnel, which is not usually detected in idiopathic CTS. CONCLUSIONS: Patients with concomitant CTS at the initial diagnosis with RA were characterized by old age, female sex, and negative ACPA. Patients with symptoms of CTS should undergo ultrasonography for early diagnosis of RA.

Association of air pollution and genetic risks with incidence of elderly-onset atopic dermatitis: A prospective cohort study.

BACKGROUND: Elderly-onset atopic dermatitis (AD) is a remarkable subtype and has been put on the agenda owing to its difficulty to control. Understanding the influence of genetic and environmental exposures is crucial to preventing elderly-onset AD. OBJECTIVES: To explore the association between genes and air pollution on incident elderly-onset AD. MATERIAL AND METHODS: This study was based on UK Biobank that recruited over 500,000 participants. The genetic risks were categorized into low, intermediate, and high groups according to tertiles of polygenic risk scores. Mixed exposure to various air pollutants was assessed using the weighted quantile sum (WQS) and also categorized based on tertiles. Within each genetic risk group, whether air pollutant mixture was associated with incident elderly-onset AD was estimated. RESULTS: 337,910 participants were included in the final analysis, and the mean age was 57.1. The median years for follow-up were 12.0, and the incident cases of AD were 2545. The medium and high air pollution mixture was significantly associated with incident AD compared with the low pollution group, with HRs of 1.182 (P = 0.003) and 1.359 (P < 0.001), respectively. In contrast, HR for medium and high genetic susceptibility was only 1.065 (P = 0.249) and 1.153 (P = 0.008). The population-attributable fraction of air pollution and genetic risk was 15.5 % (P < 0.001) and 6.4 % (P = 0.004). Additionally, compared with low genetic risk and low air pollution, high genetic risk and high air pollution was significantly associated with the incidence of elderly-onset AD with a HR of up to 1.523 (P < 0.001). There were no interactive effects between each group of genetic risks and air pollution. When grouped by sex, females could observe a stronger effect by genetic and air pollutant mixture exposure. CONCLUSION: Air pollution and genetics both independently enhance the risk of newly developed AD, and the effect of air pollutants is stronger than the investigated genes.

Usefulness of ultrasound as a predictor of elderly-onset rheumatoid arthritis with polymyalgia rheumatica-like onset.

OBJECTIVES: Differentiation between polymyalgia rheumatica (PMR) and elderly-onset rheumatoid arthritis (EORA), especially in elderly patients, is often difficult due to similarities in symptoms and serological kinetics. In this study, we aimed to analyse the predictors of EORA with PMR-like onset. METHODS: Seventy-two patients diagnosed with PMR, who attended our hospital for routine care and underwent musculoskeletal ultrasonography at that time were evaluated. Synovitis was evaluated semi-quantitatively (0-3) by grey scale (GS) and power Doppler (PD) in 24 joints [both hands (wrist, metacarpophalageal, and proximal interphalangeal joints) and both shoulder joints]. RESULTS: Overall, 18 patients had rheumatoid arthritis (25.0%); the mean age was 75.0 years, and 34.7% and 65.3% were male and female, respectively. In PMR and PMR/EORA groups, multivariate logistic analysis showed that rheumatoid factor positivity, GS ≥2 of hand joints, and PD ≥1 of hand joints were independent factors with significant differences. At least one of the three factors had a sensitivity of 88.9% and specificity of 92.6%. CONCLUSIONS: The presence of at least one of the criteria: rheumatoid factor positivity, GS ≥ 2, and PD ≥ 1 of hand joints, suggested the possibility of developing EORA within 1 year of PMR diagnosis.

Elderly-Onset Rheumatoid Arthritis: Characteristics and Treatment Options.

Elderly-onset rheumatoid arthritis (EORA) is a distinct clinical entity defined as the onset of rheumatoid arthritis (RA) in individuals aged over 60 years. EORA presents unique clinical features, including a more equitable distribution of sexes, a potential predilection for male involvement, a higher incidence of acute onset characterized by constitutional symptoms, a propensity for systemic manifestations, elevated sedimentation rates at disease onset, a reduced occurrence of rheumatoid factor positivity, increased titers of anti-citrullinated protein antibodies, a preference for involvement of large joints, elevated disease activity, the presence of bone erosions, and heightened patient disability. RA is recognized to consist of three partially overlapping subsets. One subset mirrors the classical RA clinical presentation, while the remaining subsets exhibit either a polymyalgia rheumatica-like phenotype or present with remitting seronegative symmetrical synovitis accompanied by pitting edema syndrome. In the initial stages of EORA management, non-steroidal anti-inflammatory drugs (NSAIDs) are not typically the first-line treatment choice, because seniors are much more prone to develop side effects due to NSAIDs, and the use of NSAIDs is in reality contraindicated to the majority of seniors due to comorbidities. Disease-modifying antirheumatic drugs (DMARDs), frequently methotrexate, are introduced immediately after the diagnosis is made. In cases where elderly patients demonstrate resistance to conventional DMARD therapy, the introduction of biological or targeted synthetic DMARDs becomes a viable treatment option. EORA presents a unique clinical profile, necessitating tailored treatment strategies. Our study emphasizes the challenges of NSAID use in seniors, highlighting the imperative shift toward DMARDs such as methotrexate. Future research should explore personalized DMARD approaches based on disease activity, comorbidities, and safety considerations, aiming to optimize treatment outcomes and minimize glucocorticoid reliance, thereby enhancing the quality of care for EORA patients.

Drug-resistant epilepsy at the age extremes: Disentangling the underlying etiology.

The incidence of epilepsy is highest at the extreme age ranges: childhood and elderly age. The most common syndromes in these demographics - self-limited epilepsies of childhood and idiopathic generalized epilepsies in pediatric age, focal epilepsy with structural etiology in older people - are expected to be drug responsive. In this work, we focus on such epilepsy types, overviewing the complex clinical background of unexpected drug-resistance. For self-limited epilepsies of childhood and idiopathic generalized epilepsies, we illustrate drug-resistance resulting from syndrome misinterpretation, reason on possible unexpected courses of epilepsy, and explicate the influence of inappropriate treatments. For elderly-onset epilepsy, we show the challenges in differential diagnosis possibly leading to pseudoresistance and analyze how drug-resistant epilepsy can arise in stroke, neurocognitive disorders, brain tumors, and autoimmune encephalitis. In children and senior people, drug-resistance can be regarded as a hint to review the diagnosis or explore alternative therapeutic strategies. Refractory seizures are not only a therapeutic challenge, but also a cardinal sign not to be overlooked in syndromes commonly deemed to be drug-responsive.

Epibulbar solitary myofibroma in an elderly patient: a case report.

A 93-year-old male patient presented with abrupt expansion of an old epibulbar mass at the temporal area of the left eye. He had a medical history of previously treated laryngeal cancer with surgery and radiotherapy. The tumor, despite being firmly attached to the underlying sclera, was excised completely and histopathological examinations revealed a solitary myofibroma. The patient had a 4-month uneventful follow-up with excellent wound healing. Solitary myofibroma may be a differential diagnosis for epibulbar masses in elderly patients.

Treatment strategies for elderly-onset rheumatoid arthritis in the new era.

Elderly-onset rheumatoid arthritis (EORA) is characterized by acute onset and clinical features of high disease activity. Anti-cyclic citrullinated peptide antibody (ACPA) positivity or the presence of bone erosions predicts a radiological joint destruction of EORA, but ACPA-negative EORA with a polymyalgia rheumatica (PMR) phenotype may also present. Biological disease-modifying antirheumatic drugs (bDMARDs) and Janus kinase inhibitors were beneficial both in older and in younger patients in terms of risk-benefit balance. Implementation of a treat-to-target strategy could improve EORA outcomes, but older patients have more age-related comorbidities and interstitial lung disease than younger patients. Baseline comorbidities, more frequent methotrexate dose-dependent adverse events, serious infections, cardiovascular disease events, and malignancy all influence the choice of treatment and the treatment goals for older patients. Based on articles reviewed here, it is suggested that current treatment strategies for younger patients are also useful for ACPA-positive EORA and for ACPA-negative EORA with bone erosion. Differential diagnosis of ACPA-negative EORA without erosive arthritis and PMR with peripheral manifestations is challenging, and the treatment strategy of patients presenting with this overlap phenotype remained unclear. An appropriate treatment strategy for all patients with EORA still needs to be developed.

Effectiveness and safety of treat-to-target strategy in elderly-onset rheumatoid arthritis: a 3-year prospective observational study.

OBJECTIVES: To evaluate 3-year outcomes of following a treat-to-target (T2T) strategy targeting low disease activity for patients with elderly-onset RA (EORA) and to confirm safety profile of T2T. METHODS: Treatment was adjusted to target low disease activity with conventional synthetic DMARDs, followed by biologic DMARDs (bDMARDs) in 197 MTX-naïve EORA patients (mean age 74.9 years) with moderate-to-high disease activity. Non-implementation of T2T was evaluated at week 12, 24, 36, 52, 76, 104 and 128. To evaluate risks of using MTX, bDMARDs and glucocorticoids, 2122 periods of 3 months each were analysed using Bayesian hierarchical logistic regression models. RESULTS: Of the patients, 84.7% received methotrexate, 34.0% glucocorticoids with DMARDs and 41.6% bDMARDs during the observation period. Sixty-nine of the 197 patients failed to adhere to T2T because of comorbidities or the patient's own decision: 33 failed once, 19 twice, 10 three times and 6 four times or more. Simplified disease activity index (SDAI) remission and HAQ Disability Index (HAQ-DI) ≤0.5 at 3 years were achieved in 57.8% and 70.3% of the 128 patients adhering to T2T, and 34.8% and 43.5% of the 69 patients who did not adhere to T2T, respectively, and these were significantly different. Eighty-nine serious adverse events (SAEs) of any type were reported in 61 patients. MTX, bDMARDs and glucocorticoid were not associated with SAEs when adjusted for mean SDAI during the observation period and comorbidities at baseline. CONCLUSION: T2T strategy for EORA by using MTX and bDMARDs was effective with an acceptable safety profile. Adhering to T2T led to better outcomes.

Relation of geriatric nutritional risk index with clinical risks in elderly-onset ulcerative colitis.

BACKGROUND AND AIM: Worldwide increasing aging societies have many elderlies with intractable diseases including ulcerative colitis (UC). Reportedly, each patients' frailty as well as chronological age is a clinical risk factor of elderly-onset UC (EOUC). Because malnutrition is one of the major manifestations of frailty, we aimed to investigate the effect of malnutrition on the prognosis of EOUC with geriatric nutritional risk index (GNRI), a prognostic tool for several diseases in the elderly to estimate malnutrition, and to evaluate clinical risks among EOUC patients in Japan, the world-leading aging society. METHODS: The EOUC patients (≥ 65 years at diagnosis, n = 2778) in the previous nationwide survey were classified by age and GNRI, and odds ratios (ORs) of hospitalization and UC-related surgery were determined to evaluate the effects of malnutrition on the EOUC patients as well as aging. RESULTS: The risks of hospitalization and surgery were elevated as age advanced. The value of GNRI, negatively correlated with disease activity (r = -0.53), could distinguish severe activity (cutoff ≤ 86.82, sensitivity = 0.79, and specificity = 0.77) and discriminate the EOUC patients suffering from surgery and hospitalization. In a multivariate analysis, GNRI ≤ 86.82 was a higher risk of hospitalization (OR: 4.0, 95% CI, 2.5-6.5) and surgery (OR: 2.7, 95% CI, 0.98-7.4) than cutoff age ≥ 75 years old (OR of hospitalization and surgery were 1.4 [95% CI, 0.99-2.0] and 2.3 [95% CI, 0.8-6.3], respectively). CONCLUSION: Malnutrition estimated by GNRI was significantly related with poor clinical courses of the EOUC patients, suggesting that evaluation of nutritional status at the onset might be useful for predicting risks of clinical courses.

Invasive Haemophilus influenzae type a infection and polyarthritis in a 72-year-old Japanese man: A case report.

Haemophilus influenzae is a small, nonmotile, non-spore-forming bacterium classified into 6 serotypes (a to f) and non-typeable strains that lack a capsule. Although H. influenzae serotype a (Hia) is prevalent in Canada, the United States, Brazil, Australia, across the African continent, and several other locations, it has not been reported in Japan thus far. Our case was of a 72-year-old Japanese man who sought medical consultation after presenting with chills, fever, and polyarthritis. Cultures of blood and synovial fluid from the left knee revealed H. influenzae infection. Diagnostic imaging showed poor contrast regions in both kidneys, fluid retention around both knee joints, the left shoulder joint, and both elbow joints. Subsequently, the patient was diagnosed with invasive H. influenzae infection accompanied by polyarthritis and renal infarction. 16S ribosomal RNA gene sequencing revealed that the bacterial strain was Hia. The patient was treated with antimicrobial agents and arthroscopic curettage. We present a case of invasive Hia infection accompanied by polyarthritis and renal infarction. To the best of our knowledge, this is the first case of Hia infection in Japan. The case is very rare considering that the disease occurred in an elderly patient who developed polyarthritis.

Clinical features of elderly-onset Adult-onset Still's disease.

OBJECTIVES: To clarify the characteristics of patients with elderly-onset Adult-onset Still's disease (AOSD). METHODS: Patients were classified into elderly-onset (>60 years: 47 patients) and younger-onset (≤60 years: 95 patients) groups according to their age at diagnosis of AOSD. Clinical features, treatments, and prognosis were compared between the elderly-onset and younger-onset groups. RESULTS: In the elderly-onset group, compared with the younger-onset group, typical skin rashes were less frequent (21.3% vs 58.9%, respectively; p < .0001), whereas pleuritis (27.7% vs 7.4%, respectively; p = .0011) and disseminated intravascular coagulation (19.1% vs 2.1%, respectively; p = .0004) were more frequent, and serum ferritin levels were higher (median 12,700 ng/ml vs 2526 ng/ml, respectively; p < .0001). Overall survival and AOSD-related survival were reduced (p = .0006 and p = .0023, respectively) and drug-free remission was less frequent (p = .0035) in the elderly-onset group compared with the younger-onset group. CONCLUSIONS: Our results demonstrated that elderly-onset AOSD patients had several characteristics that differed from younger-onset AOSD patients, including less typical skin lesions, more AOSD-related complications, higher ferritin levels, and poorer prognoses.

Consideration of differences in drug usage between young-onset and elderly-onset rheumatoid arthritis with target of low disease activity.

OBJECTIVES: Elderly-onset rheumatoid arthritis (EORA) is reported to differ from young-onset rheumatoid arthritis (YORA) with regard to patient background and drug treatment. We examined the amount of drug administered to patients who achieved low disease activity (LDA) for rheumatoid arthritis at our hospital. METHODS: Demographics, clinical history, and treatments were compared between patients with EORA (n = 70) and YORA (n = 190). RESULTS: There was a significant difference in the average age (73.8 vs. 57.8 years), disease duration (6.66 vs. 14.7 years), and sex (62.9% males vs. 83.7% females), but no difference in rheumatoid factor positivity (85.3% vs. 80.7%), anti-citrullinated peptide antibody positivity (86.5% vs. 87.7%), simplified disease activity index (4.28 vs. 4.59), or disease activity score 28-CRP (1.99 vs. 2.04) in the EORA and YORA groups, respectively. There were also no significant differences in prednisolone use (37.1% vs. 36.3%), amount of methotrexate administered (MTX) (1.45 vs. 1.41 mg), and MTX use (55.7% vs. 65.3%). However, the MTX dose (2.89 vs. 4.09 mg/week, p = .011) and overall biologics use (32.9% vs. 56.3%, p = .0012) were significantly lower in patients with EORA than in those with YORA. CONCLUSION: Patients with EORA may be able to achieve LDA with lower drug dosage than those with YORA.

Subcutaneous Tocilizumab Is Effective for Treatment of Elderly-Onset Rheumatoid Arthritis.

Rheumatoid arthritis (RA) is an autoimmune disease characterized by systemic articular and bone manifestations and its pathogenesis is driven by a complex network of proinflammatory cytokines, including tumor necrosis factor and interleukin (IL)-6. Treatment of rheumatoid arthritis (RA) has been standardized by the introduction of a treat-to-target approach. Subcutaneous tocilizumab (TCZ-SC) is a humanized anti-IL-6 receptor monoclonal antibody, and is widely used for refractory RA patients in the clinical settings. However, it remains unknown whether TCZ-SC shows effectiveness for elderly onset RA. The study was aimed to assess the effectiveness and safety of TCZ-SC in elderly-onset rheumatoid arthritis (EORA) patients in daily practice. Fifty-five RA patients were divided into two age groups upon TCZ-SC administration: young (Y) group (< 65 years old, n = 30) and elderly-onset (EO) group (> 65 years old, n = 25). Disease activity score-28 (DAS28) upon TCZ-SC administration (4.84 in EO group vs. 4.41 in Y group) was significantly decreased to 1.94 vs. 1.93 at 3 months and 1.61 vs. 1.75 at 12 months after administration. The clinical remission (DAS28 < 2.6) rate was 75% in EO group vs. 83% in Y group at 3 months and 90% vs. 85% at 12 months. The retention rate at 12 months was 88% in EO group and 92% in Y group without significant difference. The cessation cases of adverse events were two in each group. In conclusion, TCZ-SC showed good clinical effectiveness and safety in EORA patients. TCZ-SC is a useful agent for patients with EORA.

[Clinical characteristics of elderly and younger onset rheumatoid arthritis].

Objective: To compare the clinical and laboratory characteristics and therapy methods of elderly onset rheumatoid arthritis (EORA) and younger onset rheumatoid arthritis (YORA). Methods: The clinical, laboratory and therapeutic data of 481 RA patients in the Department of Rheumatology and Immunology in Peking University Third Hospital from January 2013 to December 2018 were collected and used to analyze the difference of characteristics between EORA group and YORA group, which might be useful for better diagnosis and treatment of EORA patients. Quantitative data of normal distribution were compared with t test between the two groups. Results: There were 481 patients in this cohort, of which 137(28.5%) were EORA, 344(71.5%) were YORA, with a mean age of (59±14) years (19-87 years). There were 358 females (74.4%) and 123 males (25.6%). The percentage of male patients was obviously higher in EORA group (36.5% vs 21.2%, χ(2)=12.012, P<0.01), and the average disease course was obviously shorter (Z=-7.985, P<0.01). Disease Activity Score 28 (DAS28) score was higher in EORA group (5.6±1.3 vs 5.2±1.6, t=2.549, P<0.05), meanwhile the incidences of pleural effusion and interstitial lung disease (ILD) were higher (6.6% vs 1.7%, 29.9% vs 18.3%, respectively; χ(2)=7.550, 7.797, both P<0.05). The incidences of venous thrombosis, primary hypertension, diabetes mellitus, cerebrovascular disease, coronary heart disease (CHD), peripheral atherosclerosis and cataract in EORA group were all significantly higher than those in YORA group (all P<0.05). Erythrocyte sedimentation rate (ESR) and D-Dimer in EORA group were all remarkably higher (both P<0.05). The rate of using glucocorticoid in EORA group was higher but the rate of using methotrexate and anti-tumor necrosis factor-α agents were lower (χ(2)=5.271, 8.407, 9.356, all P<0.05). Conclusion: Compared to YORA group, the percentage of male patients and disease activity of EORA group are higher. The occurrence of pleural effusion, ILD, venous thrombosis, primary hypertension, diabetes mellitus, cerebrovascular disease, CHD, peripheral atherosclerosis and cataract in EORA group are higher than those in YORA group.

[Successful treatment with enzyme replacement therapy for pelvic fragile fracture in an elderly case of type I Gaucher's disease].

A 76-year-old male with lower-limb weakness was admitted to our hospital where thrombocytopenia and anemia were noticed. CT showed massive splenomegaly and multiple nodules inside the spleen. Bone marrow examination showed an increase of macrophages with large cytoplasm. Suspected of splenic lymphoma, the patient underwent splenectomy. Spleen specimens were histologically analyzed and suggested the probability of Gaucher's disease (GD). Leukocyte glucocerebrosidase (GBA) enzyme activity had decreased to 1.25 nmol/mg, and mutation analysis of GBA revealed two missense variants, p.D448H (D409H), p.L483P (L444P), which confirmed the diagnosis of type I GD. Fourteen months after splenectomy, he developed right buttock pain, and pelvic magnetic resonance imaging showed a fragile right pubic and pelvic fracture. We initiated injection of imiglucerase as enzyme replacement therapy (ERT) and administered bisphosphonate. His symptoms gradually improved without surgical treatment. In addition, thrombocytopenia and anemia also improved, and angiotensin-converting enzyme levels decreased. Type I GD should be considered a differential diagnosis of giant splenomegaly and thrombocytopenia, even in the elderly. ERT or substrate reduction therapy should be administrated to GD patients, while paying attention to the development of bone lesions.

Subjective sleep disturbances at the time of diagnosis in patients with polymyalgia rheumatica and in patients with seronegative elderly-onset rheumatoid arthritis. A pilot study.

OBJECTIVES: To investigate subjective sleep disturbances in patients with recent-onset polymyalgia rheumatica (PMR) and in patients with recent-onset seronegative elderly-onset rheumatoid arthritis (SEORA). MATERIAL AND METHODS: The study involved patients consecutively referred to two outpatient clinics from January to June 2018, with a diagnosis of PMR according to 2012 European League Against Rheumatism and American College of Rheumatology provisional criteria, and patients with a diagnosis of SEORA according to 1987 American Rheumatism Association criteria + age + absence of rheumatoid factor and anti-citrullinated peptide antibodies. All patients were naive to glucocorticoid (GC) therapy. After informed consent, we asked the patients to fill out a questionnaire including the Medical Outcomes Study - Sleep Scale (MOS-SS), pain Visual Analogic Scale (VAS), Cumulative Illness Rating Scale (CIRS), Neuropsychiatric Inventory (NPI), and how many minutes their morning stiffness (MS) lasted, at baseline and after 1 (T1) and 12 (T2) months. Differences between groups were calculated with the t-test; all p-values were two-sided and p < 0.05 was used to determine statistical significance. The study was approved by the local ethics committee and carried out in accordance with the Helsinki Declaration. RESULTS: The MOS-SS scores and MS duration were the only variables to show at T0 a significant difference between the two groups. In particular, MOS-SS scores were 47.6 ±8.4 (PMR) and 28.26 ±12.4 (SEORA), with p-values = 0.000. The MS duration was 90 ±9.9 minutes and 45 ±5.5 minutes, with p-value = 0.000. At T1 and T2, MOS-SS scores and MS duration decreased in the two groups, and no significant differences were found. CONCLUSIONS: The study suggests that the assessment of subjective sleep disturbances can be useful in the differential diagnosis between recent-onset PMR and SEORA.

Clinical differences between elderly-onset ulcerative colitis and non-elderly-onset ulcerative colitis: A nationwide survey data in Japan.

BACKGROUND AND AIM: Studies on the characteristics of elderly-onset ulcerative colitis (EOUC) and non-elderly-onset ulcerative colitis (NEOUC) have reported conflicting findings. The aim of this study was to compare disease characteristics of EOUC and NEOUC by analyzing the database of the Japanese nationwide inflammatory bowel disease (IBD) registry. METHODS: We analyzed the age of disease onset, sex, disease severity, and disease extent in patients with ulcerative colitis that were newly diagnosed and registered within 1 year between 2004 and 2009 (n = 28 179). We also analyzed the medical treatment, rate of IBD-related surgery, and postoperative complications. We compared them between younger than 65 years old (NEOUC group) and 65 years old or older (EOUC group) patients. RESULTS: A total of 25 401 (90.1%) and 2778 (9.9%) patients were included in the NEOUC and EOUC groups, respectively. In the EOUC group, disease activity was significantly higher, and extent of pathological changes in the colon more extended significantly. Laboratory findings showed that inflammatory markers were elevated significantly in the EOUC group. The proportion of those with IBD-related hospitalization was significantly higher in the EOUC group (54.2% vs 35.7%, P < 0.001). The proportion of patients who were treated with corticosteroids was significantly higher in the EOUC group (36.7% vs 30.8%, P < 0.001). Significantly more number of patients underwent IBD-related surgery in the EOUC group (0.68% vs 0.27%, P < 0.001). CONCLUSION: Elderly patients show higher disease activity, with a higher proportion requiring IBD-related hospitalization and IBD-related surgery, according to the nationwide registry in Japan.

Elderly-Onset and Adult-Onset Ulcerative Colitis Are More Similar than Previously Reported in a Nationwide Cohort.

BACKGROUND: Elderly-onset ulcerative colitis (EO-UC) is recognized as a distinct subpopulation of UC. To our knowledge, there have been no nationwide studies of EO-UC populations in the USA. AIMS: We aim to characterize differences in presentation at diagnosis and clinical course between EO-UC and adult-onset UC (AO-UC) patients in a national cohort. METHODS: Complete medical records of patients newly diagnosed with UC from October 2001 to October 2011 in the Veterans Affairs health system were obtained. Patients were followed until colectomy, death, or the end of the observation period on November 2015. EO-UC patients (age of diagnosis ≥65 years) were compared to AO-UC patients (age of diagnosis ≤40 years) with respect to demographic, severity, and therapeutic data. Statistical analysis was performed using JMP statistical software. RESULTS: We identified 836 newly diagnosed UC patients, of which 207 had EO-UC and 102 had AO-UC. The mean age of diagnosis was 72.4 years (EO-UC) and 32.9 years (AO-UC), with a mean 8-year follow-up period. The incidence of pancolitis at the time of diagnosis was similar between both groups (p = 0.67). There was no difference in steroid use (36.7 vs 45.1%, p = 0.1563), thiopurine use (19.3 vs 22.6%, p = 0.5081), and colectomy rates (6.3 vs 5.9%, p = 0.8911) between EO-UC and AO-UC populations. There was lower anti-TNF use in EO-UC patients compared to AO-UC patients (5.8 vs 14.7%, p = 0.0091). CONCLUSION: In this nationwide cohort, we found that the use of steroids, thiopurines, and colectomy was similar in both populations, while anti-TNF use was lower among the elderly.
