REMITTING SERONEGATIVE SYMMETRICAL SYNOVITIS WITH PITTING EDEMA (RS3PE) IN A 75-YEAR-OLD WOMAN: A CASE REPORT

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare inflammatory condition seen in elderly people. The disease is a syndrome characterized by sudden-onset swelling and pitting edema, holding hands and feet, especially in the distal extremities. RS3PE may be an alone disease or associated with malignancy, inflammatory rheumatic diseases or infections. The pathophysiology is not very clear. Its prevalence is not well known. Due to the presence in the elderly, especially polymyaljia rheumatica (PMR) and late-onset rheumatoid arthritis (LORA) is involved in the differential diagnosis. There are several criteria defined for diagnosis. Especially cases of RS3PE that are not associated with malignancy respond well to low-dose steroids. Although the relationship with cancer is known, it is not clear which patients should be screened for cancer. Our aim in this article is to present a patient with RS3PE and to remind physicians dealing with the geriatric population of the existence of RS3PE and to emphasize its importance.

Unveiling the arthritis divide: Exploring treatment response and impact in late-onset vs. young-onset rheumatoid arthritis.

Impact of osteoarthritis (OA) on the initial treatment response of rheumatoid arthritis (RA) by treat to target (T2T) practice was compared between the patients with an onset age ≥65 years old (late-onset RA [LORA]) and those with an onset age <65 years old (young-onset RA [YORA]). A retrospective study was conducted on the patients with RA, who were referred to our clinic without treatment between January 2021 and July 2022. Patients with grade ≥3 OA according to the Kellgren-Lawrence (K-L) classification either in the knee or hand were classified in the OA(+) group and others were in the OA(-) group. The clinical data were compared at the diagnosis and one year after the initial treatment between the groups for 74 LORA and 59 YORA patients, respectively. One year after starting treatment in the LORA patients, the OA(+) group had poorer disease activity control and greater disability in the several activities of daily living (ADL) than the OA(-) group. In the YORA patients, there were no differences in ADL disability between the groups. In the initial treatment of the LORA patients, the prevalence of OA was high, and impact of OA on LORA was larger than on YORA.

A preliminary survey of rheumatologists on the management of late-onset rheumatoid arthritis in Japan.

Objectives We investigated the current perspectives regarding the management of late-onset rheumatoid arthritis (LORA) among rheumatologists in clinical practice. Methods This study was performed in October 2021, and included 65 rheumatologists certified by the Japan College of Rheumatology, who were administered questionnaires (including multiple choice and descriptive formulae) regarding the management of LORA. We aggregated and analyzed the responses. Results All 65 rheumatologists responded to the survey; 47 (72%) answered that >50% of newly diagnosed patients were aged ≥65 years, 42 (65%) answered that achievement of remission or low disease activity was the treatment goal, and 40 (62%) considered patient safety to be the highest priority. Most rheumatologists are concerned about the management of conditions other than RA, such as comorbidities, financial constraints, and life circumstances that interfere with standard or recommended treatment implementation. Conclusion This preliminary survey highlighted various rheumatologists' perspectives regarding the management of LORA.

Not all geriatric cachexia is cancer - The difficult lateonset rheumatoid arthritis.

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

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. 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. 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. 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.

Trends in treatment for patients with late-onset rheumatoid arthritis in Japan: Data from the NinJa study

ABSTRACT Objectives Our objective was 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 National Database of Rheumatic Diseases in Japan were classified according to the disease onset: at &amp;lt;65 years (young-onset rheumatoid arthritis); 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 7178, 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 decreased, whereas that of non-tumor necrosis factor inhibitors increased. LORA was characterized by more single DMARD use and less methotrexate and biological/targeted synthetic DMARD use. Tumor necrosis factor inhibitors 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.

The Characteristics and Management Considerations of Late-onset Rheumatoid Arthritis.

The Characteristics and Management Considerations of Late-onset Rheumatoid Arthritis.

MANAGEMENT OF RHEUMATOID ARTHRITIS IN ELDERLY PATIENTS

Rheumatoid arthritis (RA) is a chronic inflammatory disease that is characterized by polyarthritis, progresses with joint damage, and may involve extra-articular tissue. Although RA can develop at any age, its prevalence increases with age. The number of elderly RA patients is gradually increasing due to both the increase in the frequency of late-onset (age 65 and over) RA (LORA) patients and the increased life expectancy. RA is characterized by inappropriately accelerated immune aging that occurs in the early period and is independent of disease duration. Aging can affect both the onset and the clinical phenotype of RA. Moreover, one of the most challenging issues for specialists is the treatment of RA in elderly patients. Targeted treatment of RA in elderly patients is inadequate or not optimally administered due to patients’ pre-existing comorbidities, polypharmacy, physicians’ concerns about possible drug side effects, and the lack of specific treatment guidelines for elderly RA patients. Elderly RA patients have been rarely and sometimes not even included in randomized controlled trials due to both age and comorbidities. Nevertheless, evidence for the safety and efficacy of specific RA treatments in the elderly population is gradually increasing. In elderly patients with RA, disease activity, all the comorbidities of the patient, and possible side effects of the drugs should be taken into consideration when making treatment decisions, and the treatment target should be individualized. In this review, the epidemiology of elderly RA patients, their comorbidities, briefly immune aging in RA, and the medical treatment approach in elderly RA will be discussed in light of studies.

ARTICULAR SYNDROME IN THE ELDERLY: COMMON DIFFERENTIALS AND CHALLENGES

Articular syndrome includes a spectrum of inflammatory and non-inflammatory joint involvement ranging from arthralgia to arthritis. Its phenotype, differentials and management differ slightly in the elderly, considering the added effect of physiological changes with ageing, comorbidity and multimorbidity. This review aims to provide an overview of the common differentials of articular syndrome in the elderly, including the inflammatory and degenerative causes. The common inflammatory arthritis in the elderly includes late-onset rheumatoid arthritis, polymyalgia rheumatica, paraneoplastic arthritis, crystal arthropathies, and systemic vasculitis, including ANCA-associated vasculitis, to name a few. The non-inflammatory articular syndromes in this age group predominantly include osteoarthritis and osteoporosis. There are also evident alterations in the gut microbiome associated with inflammatory arthritis and with physiological ageing and osteoarthritis, which have possible mechanistic significance. The management aspect in the geriatric population comes with challenges of addressing multimorbidity, polypharmacy, drug interactions, and not just disease activity. An integrated approach with effective physical therapy, and vocational activities, tailored to each patient is essential for optimal management.

Initiation of Disease-Modifying Antirheumatic Drugs in Older Medicare Beneficiaries With New Diagnosis of Late-Onset Rheumatoid Arthritis.

Older adults with rheumatoid arthritis (RA) account for up to one-third of the RA population and are less likely to receive optimal treatment. For the subgroup of older adults with late-onset RA (LORA), who experience more symptomatic and progressive disease, suboptimal treatment could be more consequential than the general population who age with RA. We evaluated use of disease-modifying antirheumatic drugs (DMARDs) in older adults with a new diagnosis of LORA. In this retrospective observational study, we identified adults 66 years of age or older with a new diagnosis of LORA using Medicare data from 2008 to 2017. Information on baseline patient characteristics and DMARD initiation during the first 12 months after LORA diagnosis were collected. We also assessed concomitant use of glucocorticoids (GCs). We identified 33,373 older adults with new diagnosis of LORA. Average age at LORA diagnosis was 76.7 (SD 7.6); 75.4% were female, 76.9% were White, and 35.6% had low-income subsidy (LIS). Less than one-third were initiated on a DMARD (28.9%). In multivariable analyses, DMARD initiation was associated with younger age, fewer comorbidities, and absence of LIS status. Concomitant long-term (>3 months) GC use was higher among those on any DMARD (44.3%) compared with those without (15.2%). DMARD initiation after new diagnosis of LORA is low despite current clinical practice guidelines recommending early aggressive initiation of treatment. Long-term GC use is common among those on any DMARDs, raising concern for suboptimal DMARD use. Further studies are needed to understand drivers of DMARD use in older adults.

Effects of oral contraceptives and menopausal hormone therapy on the risk of rheumatoid arthritis: a prospective cohort study.

Oral contraceptives (OC) and menopausal hormone therapy (MHT) contain exogenous sex hormones and are used by millions of women around the world. However, their effect on the development of rheumatoid arthritis (RA) is still debated and the current literature suggests that they may exert opposite effects on the risk of RA. The present study aimed to estimate the effects of exogenous hormones on the development of RA, both during the reproductive lifespan and later in life. The association between OC and RA, as well as between MHT and late-onset RA (LORA), was investigated using time-dependent Cox regression modelling in white British women from the UK Biobank (n = 236 602 and n = 102 466, respectively) and replicated in women from all ethnic groups. OC use was associated with a decreased risk of RA in ever-users [hazard ratio (HR) = 0.89; 95% CI = 0.82-0.96], as well as in current (HR = 0.81; 0.73-0.91) and former users (HR = 0.92; 0.84 -1.00), compared with never-users. In contrast, MHT use was associated with an increased risk of LORA in ever-users (HR = 1.16; 1.06-1.26) as well as in former users (HR = 1.13; 1.03-1.24) compared with never-users. OC use appears to protect against RA, while MHT may increase the risk of LORA. This study provides new insights into the possible inverse effect of exposure to different exogenous sex hormones on the risk of RA.

Clinical characteristics of rheumatoid arthritis patients with interstitial lung disease: baseline data of a single-center prospective cohort

BackgroundTo introduce a prospective cohort for rheumatoid arthritis (RA) patients with interstitial lung disease (ILD) and to identify their clinical features in comparison with RA patients without ILD.MethodsUsing a multidisciplinary collaborative approach, a single-center cohort for RA patients with ILD (RA-ILD) was established in May 2017, and enrolment data from May 2017 to March 2021 were used to compare the clinical features of RA patients without ILD (RA-non ILD). Multivariable logistic regression analysis was used to identify factors associated with ILD in RA patients.ResultsAmong 148 RA-ILD and 410 RA-non ILD patients, participants in the RA-ILD group were older (65.8 ± 9.9 vs. 58.0 ± 10.4 years, P < 0.001) and included more males (35.8% vs. 14.6%, P < 0.001) than in the RA-non ILD group. The RA-ILD group had a higher proportion of late-onset RA patients (age ≥ 60 years) than in the comparator group (43.9% vs. 14.2%, P < 0.001). Multivariable logistic regression analysis showed that higher age at RA onset (OR 1.056, 95% CI 1.021–1.091), higher body mass index (BMI; OR 1.65, 95% CI 1.036–2.629), smoking history (OR 2.484, 95% CI 1.071–5.764), and oral glucocorticoid use (OR 3.562, 95% CI 2.160–5.874) were associated with ILD in RA patients, whereas methotrexate use was less likely to be associated with ILD (OR 0.253, 95% CI 0.155–0.412).ConclusionsHigher age at RA onset, smoking history, and higher BMI were associated with the presence of ILD among RA patients. Oral glucocorticoids were more frequently used whereas methotrexate was less likely to be used in RA-ILD patients.

Efficacy and gastrointestinal tolerability of methotrexate in late-onset rheumatoid arthritis patients: a prospective cohort study

BackgroundThe proportion of the late-onset forms of disease is growing in rheumatoid arthritis (RA) population. Concerns about comorbidities and drug adverse events lead to delay or ineffective treatment in these patients. The aim of this study is to analyze the tolerability and efficacy of methotrexate therapy in late-onset RA (LORA) patients and compare the baseline characteristics, efficacy, and gastrointestinal (GIT) adverse effects of methotrexate treatment between LORA and young-onset RA patients (YORA).ResultsPatients whose symptoms began after 65 years or older were classified as LORA. Baseline characteristics, rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA) status, C-reactive proten (CRP) levels, disease activity scores, and radiographs of hands and feet were recorded. Patients were started to methotrexate therapy and followed for 6 months. Female gender was predominant in both LORA and YORA. LORA patients had less seropositivity (RF or anti-CCP), higher CRP levels, and higher DAS 28 scores. More than half of the patients (58%) had large joint involvement. Remission rates were higher in LORA patients, and total remission and low disease activity rates were similar. Methotrexate withdrawal due to gastrointestinal adverse events (nausea and vomiting) was lower than YORA patients. Logistic regression analysis demonstrated that DAS 28 score was the only predictor for disease remission (p: 0.000), and no predictive factor was found for methotrexate-related adverse events.ConclusionMethotrexate-related gastrointestinal adverse events do not increase in LORA patients, and nausea-vomiting is seen lower than YORA. Methotrexate is well tolerated and effective in LORA patients, and a large amount of patients achieve treatment targets after 6 months of treatment with MTX. Methotrexate should be started immediately in LORA without additional concerns on adverse effects.

Late-onset rheumatoid arthritis registry study, LORIS study: study protocol and design

BackgroundAlthough drug treatment strategies for rheumatoid arthritis (RA) are relatively well established, there is a paucity of evidence on the treatment in older patients. The purpose of this study is to build a registry for late-onset RA (LORA), which is expected to increase rapidly worldwide. In addition, we aim to propose optimal treatment strategies according to the patient background including frailty, thereby contributing to improving the quality of treatment and daily living in patients with RA.Methods/designThe LORIS (Late-onset Rheumatoid Arthritis Registry) Study is a prospective nation-wide multicenter observational study of patients with LORA. The inclusion criteria were patients aged ≥ 65 years at onset, meeting 2010 ACR/EULAR classification criteria for RA, and starting either any disease-modifying antirheumatic drugs (DMARDs) in a DMARD-naïve patient or the first biologic/targeted synthetic DMARDs during the study period. Enrollment was started on 11 January, 2022 and will be closed on 31 December, 2023. Patients will undergo a comprehensive baseline assessment including clinical data, medication, cognitive and physical function, psychosocial factors, and frailty. Data will be collected at baseline, Month 3, 6, 12, 18, 24, 36, and summarized descriptively. The factors associated with adverse events and achieving remission will be determined.DiscussionA multi-disciplinary panel including patients, rheumatologists, and geriatric specialists will discuss the results and build a consensus regarding the treatment goals of LORA. We expect to provide a broad range of information for evidence-based shared decision making in the treatment of LORA.Study registration: Registered at the UMIN registry (UMIN000046086) on 1 January 2022.

Late-onset rheumatoid arthritis has a similar time to remission as younger-onset rheumatoid arthritis: results from the Ontario Best Practices Research Initiative

BackgroundThe prevalence of rheumatoid arthritis (RA) in persons 60 years or older is estimated to be 2%. Late-onset rheumatoid arthritis (LORA) is traditionally defined as the onset of RA after the age of 60 years. Compared to younger-onset rheumatoid arthritis (YORA) which occurs before the age of 60 years, LORA has unique characteristics and disease manifestations. To date, few reports have addressed LORA and the prognosis of LORA patients remains unclear. We compared the clinical characteristics, time to remission and treatment regimen at remission between LORA and YORA patients.MethodsThis prospective cohort study used a registry database in Ontario, Canada from 2008 to 2020. Patients were included if they had active rheumatoid arthritis (RA) disease (≥1 swollen joint) and were enrolled within 1 year of diagnosis. LORA was defined as a diagnosis of RA in persons 60 years and older and YORA as a diagnosis of RA in persons under the age of 60. Remission was defined by Disease Activity Score 28 (DAS28) ≤2.6. A multivariable Cox proportional hazards model was used to estimate time to remission.ResultsThe study included 354 LORA patients and 518 YORA patients. The mean (standard deviation) baseline DAS28 score was 5.0 (1.3) and 4.8 (1.2) in LORA and YORA patients, respectively (p=0.0946). Compared to YORA patients, the hazard ratio for remission in LORA patients was 1.10 (95% confidence interval 0.90 to 1.34 p=0.36) after adjusting for other prognostic factors. For patients who reached remission, LORA patients were less likely to be on a biologic or Janus kinase (JAK) inhibitor (16% vs. 27%) and more likely to be on a single conventional synthetic disease-modifying anti-rheumatic drugs (csDMARD) (34% vs. 27%) than YORA patients (p=0.0039).ConclusionLORA and YORA patients had similar prognosis in terms of time to remission. At remission, LORA patients were more likely to be on a single csDMARD without a biologic or JAK inhibitor.

Inflammatory profile of incident cases of late-onset compared with young-onset rheumatoid arthritis: A nested cohort study.

To describe the characteristics of patients between late-onset rheumatoid arthritis (LORA) with young-onset (YORA), and analyze their association with cumulative inflammatory burden. We performed a nested cohort study in a prospective cohort comprising 110 patients with rheumatoid arthritis (RA) and 110 age- and sex-matched controls. The main variable was cumulative inflammatory activity according to the 28-joint Disease Activity Score with erythrocyte sedimentation rate (DAS28-ESR). High activity was defined as DAS28 ≥ 3.2 and low activity as DAS28 < 3.2. The other variables recorded were inflammatory cytokines, physical function, and comorbid conditions. Two multivariate models were run to identify factors associated with cumulative inflammatory activity. A total of 22/110 patients (20%) met the criteria for LORA (≥ 60 years). Patients with LORA more frequently had comorbid conditions than patients with YORA and controls. Compared with YORA patients, more LORA patients had cumulative high inflammatory activity from onset [13 (59%) vs. 28 (31%); p = 0.018] and high values for CRP (p = 0.039) and IL-6 (p = 0.045). Cumulative high inflammatory activity in patients with RA was associated with LORA [OR (95% CI) 4.69 (1.49-10.71); p = 0.008], smoking [OR (95% CI) 2.07 (1.13-3.78); p = 0.017], anti-citrullinated peptide antibody [OR (95% CI) 3.24 (1.15-9.13); p = 0.025], average Health Assessment Questionnaire (HAQ) score [OR (95% CI) 2.09 (1.03-14.23); p = 0.034], and physical activity [OR (95% CI) 0.99 (0.99-0.99); p = 0.010]. The second model revealed similar associations with inflammatory activity in patients with LORA. Control of inflammation after diagnosis is poorer and comorbidity more frequent in patients with LORA than in YORA patients and healthy controls.

Loneliness in patients with late-onset rheumatoid arthritis: Relationship with disease activity and psychosocial factors

Amaç: Yalnızlık hissi, kronik hastalıklar ve ağrılı durumlar ile şiddeti artan, oldukça yaygın görülen bir durumdur. Bu çalışmanın amacı, geç başlangıçlı romatoid artritli (RA) hastalarda yalnızlık hissinin araştırılması ve yalnızlık hissi ile hastalık aktivitesi ve psikososyal durum arasındaki ilişkinin incelenmesidir. Yöntem: Çalışmaya hastalık başlangıç yaşı 60 ve üzeri olan 44 RA'lı hasta ve 44 kontrol dahil edildi. Tüm katılımcıların sosyodemografik özellikleri, Beck Depresyon Ölçeği (BDÖ) ve Beck Anksiyete Ölçeği (BAÖ), Çok Boyutlu Algılanan Sosyal Destek Ölçeği ve UCLA Yalnızlık Ölçeği kısa formu (ULS-8) skorları kaydedildi. Ek olarak RA’lı hastaların eritrosit sedimantasyon hızı ve C-reaktif protein değerleri, Görsel Analog Skala-ağrı, Hastalık Aktivite Skoru ve Sağlık Değerlendirme Anketi (HAQ) skorları kaydedildi. Bulgular: RA’lı hastalarda kontrollerle karşılaştırıldığında depresyon skorları ile ULS-8 skorları daha yüksek ve algılanan sosyal destek skorları daha düşüktü ancak anksiyete açısından iki grup arasında fark yoktu. RA'lı hastalarda hem yalnızlık hem de algılanan sosyal destek BDÖ, BAÖ ve HAQ skorları ile korelasyon göstermekteydi. Aktif hastalığı olan grupta remisyona giren hastalara göre anksiyete ve depresyon puanlarının daha yüksek, algılanan sosyal desteğin daha düşük ve yalnızlık hissinin daha fazla olduğu belirlendi. Sonuç: Geç başlangıçlı RA hastalarında yalnızlık hissi; depresyon, algılanan sosyal destek, fonksiyonel durum ve hastalık aktivitesi ile ilişkilidir. Yaşlı bireylerde morbiditeyi artıran bir faktör olan yalnızlık, geç başlangıçlı RA’lı hastalarda daha şiddetli olmaktadır.

Diagnosis of COVID-19 associated arthritis in patients with or without underlying rheumatic and musculoskeletal disease supported by musculoskeletal ultrasound: a case series from three European centres.

The coronavirus disease 19 (COVID-19) pandemic concerns the field of rheumatology in many ways. Arthritis in conjunction with COVID-19 is increasingly reported. However, clinical data are still limited and there is lack of a detailed characterisation of COVID-19 associated arthritis by musculoskeletal ultrasound (MSUS). This case series reports different forms of COVID-19 associated arthritis supported by MSUS in patients with or without underlying rheumatic and musculoskeletal disease (RMD). From March 2020 to July 2021, adult patients (n=10) with arthritis timely related to COVID-19 were assessed in three European centres by clinical and laboratory values and additionally MSUS. In the group without underlying RMD (n=6), two patients presented with polyarticular arthralgia during severe COVID-19, swelling was rarely seen and MSUS demonstrated arthritis only in a few joints affected. The other four patients showed arthritis four to 16 weeks after mild or moderate COVID-19 (without hospitalisation): polyarthritis (n=1), oligoarthritis of the upper and lower limb (n=2), and in one case, late-onset rheumatoid arthritis (LORA) was newly diagnosed. In the group with an underlying RMD (n=4), an increase of disease activity was reported by MSUS during mild and mild-moderate COVID-19. In general, MSUS often presented power Doppler (PD) positive synovitis and tenosynovitis. In our patients without underlying RMD, arthritides associated with COVID-19 are comparable to the clinical picture of a reactive arthritis (ReA) or other virus-related arthritides (e.g. parvovirus B19). New onset or flares of RMD possibly triggered by COVID-19 are noteworthy.

Impact of Gender and Age-at-onset on Clinical and Medical Features of Rheumatoid Arthritis in Western Algerian Population

Background: This study aimed to demonstrate the gender and age-at-onset differences in rheumatoid arthritis (RA) in the western Algerian population and their impacts on patients' clinical features and medical management. Methods: A retrospective cross-sectional study was carried out at the Internal Medicine and Functional Rehabilitation Departments (University Hospital of Sidi-bel-Abbes region) based on medical records of over 306 RA patients diagnosed between 2016 and 2019 according to ACR 1987 criteria. Late-onset RA (LORA) was defined as disease onset at 51 years of age or older. All data were processed and analyzed via SPSS 22.0. Results: We enrolled 306 rheumatoid arthritis patients (85% women) with a mean age-at-onset of 52.47 ± 12.14. Algerian RA women were more at risk of developing type 2 diabetes (P = 0.035), hypertension (P = 0.003), and thyroid disorders (P = 0.05). We did not find any significant relationship between clinical features, laboratory data, and gender. The LORA group comprised 60.5% of our study population with a higher number of comorbidities such as hypertension (P &lt; 0.001), osteoporosis (P = 0.007), and scleroderma (P = 0.014). Nonetheless, we found evidence of an association between positive anti-CCP, RF rate, and age-at-onset (P = 0.001 and P &lt; 0.001, respectively). Conclusions: Algerian RA women with LORA presented a higher prevalence of comorbidities, while Young-onset RA (YORA) was associated with a high rate of RF.

Temporal artery biopsy for suspected giant cell arteritis: a retrospective analysis.

Temporal artery biopsy (TAB) is one of the diagnostic criteria of giant cell arteritis (GCA) according to 1990 ACR criteria and remains a tool for diagnosis. Although clinicians perform TAB with an intent to confirm suspected GCA, some biopsies result in negative and some lead to non-GCA diagnoses. We aim to review the diagnoses after TAB biopsy performed for suspected GCA and also wanted to evaluate the diagnostic changes and concomitant diseases that develop over time. The patients who had undergone TAB for suspected GCA were identified using the record entry code for TAB. Patients meeting the classification criteria for GCA were designated as the GCA group and not meeting criteria were designated as a non-GCA group. Other classification criteria were implemented for the non-GCA group diseases. A total of 51 patients (Female: 62.7%, median age: 72.1 ± 7.4years) who had undergone TAB for suspected GCA were evaluated. TAB was positive in 23 (69.6%) of the 33 patients who met the GCA classification criteria. No significant difference was found between TAB-positive and TAB-negative GCA patients in terms of clinical and laboratory parameters. In the non-GCA group, 12 patients had isolated polymyalgia rheumatica (PMR), and the diagnoses of the remaining six patients were as follows: four large vessel vasculitis (LVV) not satisfying GCA diagnostic criteria, one chronic myelomonocytic leukemia (CMML), and one amyloidosis. TAB was negative in all patients with isolated PMR. TAB showed primary amyloidosis in one patient. Out of 33 GCA patients, 21 had "isolated" GCA, four had GCA + Rheumatoid arthritis (RA), seven had GCA + PMR, and one had GCA + polymyositis. RA was diagnosed antecedent to GCA in two patients, and after GCA in the other two patients. One of the patients had developed GCA 20years after polymyositis had been diagnosed. TAB was found to be positive in two-thirds of patients with suspected GCA. Late-onset RA and rarely other inflammatory rheumatic diseases may develop in the course of GCA.
