Classification Criteria For Rheumatoid Arthritis Research Articles

Significance of High-Frequency Sonography for the Subclinical Progression of Rheumatoid Arthritis.

This study aims to investigate the use of high-frequency sonography as a tool for detecting inflammatory and destructive changes in the hand and foot joints of patients with early and long-term RA. This study employs a prospective cohort design involving 162 patients diagnosed with Rheumatoid arthritis (RA) who meet the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria. Patients were divided into two groups based on disease duration: Group 1 (n = 74) included patients with a disease duration of up to 2 years, or early РА (ERA;), Group 2 (n = 88) consisted of patients with a disease duration exceeding 2 years, or long-term persistent РА (LtRA). All patients underwent a clinical assessment of their joints, as well as radiography and arthrosonography, at the beginning of the study and again at 6 and 12 months later. In the general group of patients, ultrasound examination revealed signs of synovitis in the joints of the hands more frequently (66%) compared with clinical examination (56% by a number of swollen joints [NSJ] and 55% by a number of painful joints [NPJ], P < .01). After 6 months of treatment, 12% of the patients achieved full US remission and 24% achieved partial US remission. Within the scope of comprehensive RA diagnostics, arthrosonography of the joints of the hands and feet, utilizing a combination of greyscale and power Doppler, may surpass radiography in detecting early RA. This method allows for a more accurate assessment of disease activity and progression rates.

E062 Nailfold capillaroscopy: its application in routine clinical practice

Abstract Background/Aims Nailfold capillaroscopy (NFC) is a non-invasive tool to evaluate the structural microvascular abnormalities found in systemic sclerosis (SSc). NFC allows for the visualization of the capillary bed at the nailfold, providing valuable insights into the structure and function of these capillaries. NFC helps differentiate primary from secondary Raynaud’s phenomenon (RP). Abnormal NFC is included in the 2013 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria and due to its predictive value of developing SSc is included in the Very Early Diagnosis of SSc (VEDOSS) criteria. Dudley Group NHS FT runs a consultant-led service supported by a specialty trainee where clinical review is carried out alongside NFC using video capillaroscopy. Patients can be referred to this clinic from rheumatology or respiratory colleagues. Methods We audited all patients who had attended a monthly NFC clinic between September 2021 and October 2023. We reviewed clinical letters and electronic patient record system and collected details of: demographics; immunology; clinical characteristics; reason for attending the clinic; NFC findings; and diagnosis. NFC findings were classified as normal or abnormal (to include scleroderma pattern and non-specific changes). Data was analysed using excel for individual variables and their comparison with nailfold capillaroscopy results. Results We identified 80 patients, of which 63 (79%) were females and median age was 54.5 years. ANA was positive in 64 (80%) patients, SSc and myositis immunology blots were positive in 41 (51%) and 4 (5%) respectively. Clinical characteristics included RP in 71 (89%) and interstitial lung disease (ILD) in 17 (21%). The reasons for attending the NFC clinic were categorised as: to exclude secondary causes of RP (52; 65%); to aid diagnosis of suspected SSc (23; 29%); surveillance of known SSc (5; 6%). NFC was normal in 42 patients. In the 38 patients where NFC was abnormal the clinical diagnosis was categorised as: primary RP (8; 10%); SSc spectrum of disease (17; 21%); and another CTD (20; 25%). Of patients with SSc spectrum of disease: 24% (4/17) had a diagnosis of VEDoSS; 47% (8/17) Limited Cutaneous SSc; and 29% (5/17) Diffuse SSc. The presence of RP and ANA was not significantly different in patients with abnormal NFC. There was a non-significant association between the presence of ILD and abnormal NFC. 9/17 (52%) patients with ILD had an abnormal NFC compared to 18/63 (29%) patients without ILD (p = 0.059). Conclusion NFC is a simple procedure in conjunction with a clinical review to enhance the early diagnosis of SSc and exclusion of secondary Raynaud’s. It supports education and training as a tool for learning as being part of the curriculum. Disclosure S.A. Tabassum: None. K.M.J. Douglas: None. E. Udeshika: None.

Treatment for Rheumatoid Arthritis Associated With Alterations in the Gastrointestinal Microbiota.

Emerging research suggests that rheumatoid arthritis (RA) is associated with intestinal dysbiosis. This prospective pilot study evaluates changes in intestinal microbial composition in patients with RA initiating treatment with either methotrexate (MTX) or a tumor necrosis factor inhibitor (TNFi). Consecutive patients, fulfilling the 2010 American College of Rheumatology/EULAR classification criteria for RA, who started treatment with either MTX or TNFi delivered a stool sample upon initiation of immunosuppression and 3 months later. A 16S ribosomal RNA gene-based validated microbiota test (GA-map Dysbiosis Index Score [DIS], Genetic Analysis, Oslo, Norway) was used to evaluate for the presence and degree of dysbiosis. Fecal levels of Prevotella copri (P. copri) were analyzed by custom-made quantitative polymerase chain reaction. Changes in microbial composition were analyzed in relation to changes in disease activity, as measured by the disease activity score based on 28-joint counts, using C-reactive protein. At baseline, dysbiosis was present in 33 of 50 (66%) participants and more common in participants with more than 2 years of disease duration (P = 0.019). At the 3-month follow-up, 27 of 50 (54%) were good treatment responders and the DIS had improved in 14 of 50 (28%). Participants initiating TNFi more often exhibited improvement in the DIS compared with those initiating MTX (P = 0.031). P. copri was identified in 32 of 50 (64%) at baseline. An improvement in disease activity score based on 28-joint counts, using C-reactive protein was associated with a simultaneous decrease in P. copri abundance (rs = 0.30, P = 0.036). This study affirms that dysbiosis is a feature of RA. Although patients were not randomized to MTX or TNFi, the findings suggest that specific therapies may differentially modulate the gastrointestinal microbiota in RA. The association between P. copri and treatment response requires further study.

Classification of rheumatoid arthritis: is it time to revise the criteria?

Classification criteria have been developed for rheumatoid arthritis (RA) and other rheumatic diseases in order to gather a homogeneous patient population for clinical studies and facilitate the timely implementation of therapeutic measures. Although classification criteria are not intended to be used for diagnosis, they are frequently used to support the diagnostic process in clinical practice, including clinical decision-making. The 2010 American College of Rheumatology (ACR)/European Alliance of Associations for Rheumatology (EULAR) classification criteria for RA are capable of identifying the majority of symptomatic patients with RA already in the earliest stages of the disease who are not yet showing radiographic changes. These patients will also profit from the early implementation of therapy with disease-modifying antirheumatic drugs (DMARDs). However, the risk of misclassification is higher as compared with the former 1987 ACR criteria, which were considerably less sensitive to the recognition of patients with early RA. Of note, the presence of rheumatoid factors (RFs) and anticitrullinated protein antibodies (ACPAs) has been attributed equal weight in the 2010 ACR/EULAR criteria and may contribute up to 50% of the score needed for being classified as RA. However, while ACPAs have been proven to be the most specific serological markers of RA, the specificity of RF is moderate, especially at lower titres. This may lead to the misclassification of RF-positive patients and, consequently, the unjustified implementation of DMARD therapy. Therefore, issues arise on how comprehensive the criteria should be and whether they should be updated and adapted to findings from the past two decades that might increase both their specificity and sensitivity.

Headache-Related Characteristics of Biopsy-Confirmed Giant Cell Arteritis and the Relationship of Transmural Inflammation With Artery Tenderness and Chordal Thickening.

Giant cell arteritis (GCA) is characterized by headaches, but few studies have examined the detailed characteristics of pathologically confirmed cases. We investigated the characteristics of GCA patients, particularly headache, and their correlation with pathological findings. We retrospectively analyzed 26 patients (median age: 77.5 years, male: 38.4%) with GCA who underwent superficial temporal artery (STA) biopsy at the Japanese Red Cross Shizuoka Hospital between May 2001 and February 2022. All patients fulfilled the American College of Rheumatology and European League Against Rheumatism classification criteria for GCA. We focused on the relationship between clinical features, especially headache, and pathological findings. Twenty-four patients had unilateral, nonpulsatile, intermittent headaches. Transmural inflammation (TMI), a characteristic pathology of GCA, was present in 14 patients. Bivariate analysis revealed significant associations between the TMI and STA-related tenderness (odds ratio [OR]=11, 95% confidence interval [CI]=1.14 to 106.43, p=0.046) and the TMI and STA-related chordal thickening (OR=0.19, 95% CI=0.068 to 0.52, p=0.021). Headache in GCA patients was often unilateral, nonpulsatile, and intermittent. This study highlights the significant association of TMI with STA tenderness and ligamentous thickening, which has not been reported previously. Abnormal STA findings were significantly associated with pathological changes in GCA patients, emphasizing the importance of these lesions in predicting GCA.

Prevalence of different types of surgery in Rheumatoid arthritis patients: A study based on registry data of Rheumatologic clinic, Rafsanjan 2022

Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease that can affect many organs, and due to its systemic nature, it seems that some types of surgeries are more prevalent in this disease. This study aimed to investigate the prevalence of different types of surgery in RA patients. This retrospective study using the RA registry was performed on 639 RA patients in the rheumatology clinic of Rafsanjan, Iran, 2022. All patients fulfilled the ACR/EULAR 2010 classification criteria for RA. Demographic information, clinical parameters, laboratory information, surgical history, and surgery time were collected from the medical records. The sample comprises 555 (86.9%) women and 84 (13.1%) men. The average age was 55.08 ± 12.52, and the mean duration of the disease was 7.32 ± 5.94. There was a history of at least one surgery in 252 (39.4%) patients. The prevalence of gastrointestinal, gynecological, orthopedic, eye, ear, nose, and throat, cardiovascular and urological surgeries was 18%, 16.4%, 9.2%, 8.3%, 3.9%, 0.9% and 0.9%, respectively. There were 69.8% of eye surgeries and 57.6% of orthopedic surgeries after disease diagnosis; other surgeries were more prevalent before the diagnosis. The average age (58.16 ± 11.89 vs. 53.07 ± 12.53, P-value &lt; 0.001) and body mass index (29.65 ± 5.68 vs 28.63 ± 5.56, P-value = 0.025) were higher in participants with surgery than those with no surgery. The most prevalent surgeries were gastrointestinal, gynecological, and orthopedic surgeries, and Cardiovascular and urological surgeries were the least. The mean age and body mass index in patients with surgery were significantly higher than those without surgery. Also, physical activity was significantly lower in the participants with surgery.

Examining the clinical and radiological landscape of rhupus: navigating the challenges in disease classification.

Rhupus, in the broad sense,refers to an overlap between rheumatoid arthritis (RA) and lupus. However, there is a paucity of data on the appropriate diagnostic/classification criteria that should be used to define rhupus. Hence, we undertook this narrative review to analyze the clinical characteristics, radiology, and treatment with a focus on diagnostic challenges and defining features of rhupus. The databases of Medline/PubMed, Scopus, and DOAJ were searched for relevant articles using the following keywords: ("Rhupus"), ("lupus" AND "erosive" AND "arthritis"), and ("lupus" AND "rheumatoid arthritis" AND "overlap").Studies have used a variety of classification criteria for rhupus of which a combination of the latest classification criteria for RA and lupus along with positive anti-cyclic citrullinated peptide, anti-Smith, and anti-dsDNA antibodies seem most relevant. The majority of rhupus cohorts report the onset of the disease asRA (two-thirds of rhupus patients) followed by the development of features of lupusat an average interval of 3-11.3years. The radiographic features and distribution of erosions are similar to RA. However, ultrasonography and MRI reveal erosions in pure lupus relatedarthritis as well. This makes the reliability of radiologic tools for the evaluation of rhupus supportive at the most. Extra-articularfeatures in rhupus are mild with majororgan involvement in the form of neuropsychiatriclupus and lupus nephritis beingrare. We have further discussed the fallacies of the variousclassification criteria and proposed a theme for classifying rhupus which needs to be tested and validated in future studies. Our current state of understanding supports rhupus as an overlap of SLE and RA with articular disease similar to RA with the extra-articular disease being milder than SLE. Developing standardized classification criteria for rhupus will help in the early diagnosis and prevention of articular damagein patients with rhupus.

A case of seronegative microscopic polyangiitis following the diagnosis of renal pelvic carcinoma.

The incidence rate of malignancy in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is higher than that in the general population. Malignancy has been indicated to be a risk factor or inducer of AAV. Herein, we report the case of a healthy 84-year-old man with seronegative microscopic polyangiitis (MPA) after thediagnosis of renal pelvic carcinoma. Four weeks before admission, his estimated glomerular filtration rate (eGFR) was 85ml/min/1.73m2, and nohematuria or proteinuria was detected. Renal biopsy on admission revealed invasive urothelial carcinoma of the right renal pelvis. On day 15, his eGFR decreased to 30ml/min/1.73m2 without any incitement. The renal specimen extracted via right robot-assisted nephroureterectomy indicated the presence of ANCA-associated glomerulonephritis. On day 37, urinary protein/urinary creatinine level of 6.48g/gCre, serum albumin level of 2.1mg/dL, and eGFR of 20ml/min/1.73m2 indicated the presence of nephrotic syndrome. His blood sputum was analyzed via chest computed tomography, which revealed alveolar hemorrhage. Although his myeloperoxidase-ANCA was negative, he was diagnosed with MPA based on the 2022 American College of Rheumatology/European League Against Rheumatism classification criteria. This is the first case report of MPA orAAV complicated with renal pelvic carcinoma. The clinical indicators demonstrated that renal pelvic carcinoma preceded the onset of MPA. The spatial proximity of both diseases indicated that renal pelvic carcinoma had some influence on MPA development via the mechanism of inflammatory cytokines or neutrophil extracellular traps. Our report may be useful in elucidating the mechanism of MPA development.

Clinical features of patients with connective tissue disease with anti-human upstream binding factor antibodies: A single-center retrospective study.

Anti-human upstream-binding factor (anti-hUBF) antibodies have been reported predominantly in patients with connective tissue diseases (CTDs); these have also been reported in patients without CTDs such as hepatocellular carcinoma. Because of the low frequency of expression and few case reports, there is no consensus on the clinical significance of these antibodies. Thus, we aimed to examine the clinical features of patients with anti-hUBF antibodies and analyzed 1042 patients with clinically suspected CTDs. The presence of anti-hUBF antibodies was screened using immunoprecipitation assays. Of the 1042 patients, 19 (1.82%) tested positive for anti-hUBF antibodies; among them, 10 (56%) were diagnosed with undifferentiated CTD (UCTD), six with systemic sclerosis (SSc) and three with other diseases. Five of the 10 patients with UCTD were referred to our hospital with suspected SSc. None of the five patients fulfilled the 2013 American College of Rheumatology/European League Against Rheumatism classification criteria, but three scored seven points, a relatively high score. Six anti-hUBF-positive patients with SSc had a significantly lower modified Rodnan skin score (mRSS) than that of anti-hUBF-negative patients with SSc (2 [0-2] vs 7 [0-49], p < 0.01). Compared with anti-topoisomerase I-positive patients, anti-hUBF-positive patients had a significantly lower mRSS (2 [0-2] vs 13 [0-42], p < 0.01) and lower incidence of scleroderma renal crisis (0 of 6 vs 8 of 184, p < 0.01). Compared with anti-centromere-positive patients, anti-hUBF-positive patients had a higher incidence of interstitial lung disease (ILD), but the difference was not statistically significant (4 of 6 vs 19 of 239). In conclusion, anti-hUBF antibodies were predominantly detected in patients with CTDs and UCTD. In patients with CTDs, SSc exhibited a high ratio, displaying a lower mRSS and higher incidence of ILD. In patients with UCTD, careful follow-up is recommended as they may develop CTDs in the future.

A Rare Manifestation of IgG4-Related Disease and Secondary Hypereosinophilic Syndrome: A Case Report.

We report a case of IgG4-related disease with marked eosinophilia. A 79-year-old woman was admitted due to diarrhea, and weight loss. Cervical lymphadenopathy, bilateral submandibular glands swelling, anemia (Hb8.5g/dl), hypereosinophilia (9,750/μL), and elevated serum creatinine (1.57 mg/dL), pancreatic amylase (191 IU/L), and IgG4 (3,380 mg/dL) were found. Diffusion-weighted image on MRI showed high intensity signals inside of both the pancreas and the kidney. The echogram of submandibular glands revealed cobblestone pattern. Kidney biopsy revealed acute tubulointerstitial nephritis. Biopsies of lip, gastrointestinal tract and bone marrow showed infiltration of lymphoplasmacytic cells and IgG4 positive plasma cells (30-67/HPF). Gastrointestinal and bone marrow biopsies also showed eosinophilic infiltration. Adrenal insufficiency, rheumatic disease, tuberculosis, parasite infection, drug induced eosinophilia, and eosinophilic leukemia were all ruled out. We started treatment with 40mg of prednisolone and her general condition rapidly improved. The eosinophil count, serum IgG4, and serum creatinine decreased. We gradually tapered prednisolone and maintained 5mg/day. During the 5 years of treatment, she had no recurrence of the symptom. According to the 2019 American College of Rheumatology/European League Against Rheumatism classification criteria for IgG4-related disease, eosinophils > 3000/μL is one of the exclusion criteria. If we comply this criterion, the diagnosis of IgG4-related disease should be avoided. However, our case fit the diagnostic criteria of type I autoimmune pancreatitis, IgG4-related sialadenitis and global diagnosis of IgG4-related disease. We finally diagnosed our case as IgG4-related disease with secondary hypereosinophilic syndrome. This case suggests that IgG4-related disease with eosinophils > 3000/μL does exist in the real world.

Factors associated with severe infection in rheumatoid arthritis patients: lessons learned from the COVID-19 pandemic.

This aimed to identify the factors associated with severe/critical coronavirus disease 2019 (COVID-19) infection in rheumatoid arthritis (RA) patients. Two-hundred RA patients diagnosed according to the American College of Rheumatology/ European League Against Rheumatism (ACR/EULAR) classification criteria with proven COVID-19 infection were recruited and categorized according to the world health organization (WHO) COVID-19 severity grading into 2 groups: patients with mild/moderate COVID-19 (n = 164) and patients with severe/critical COVID-19 (n = 36). Comparison between both groups was done to identify the risk factors associated with severe/critical infection. Incidence of RA disease activity flare defined as increase in clinical disease activity index (CDAI) more than 10 points following infection was calculated. Multivariate analysis identified history of previous serious infection, age > 60years, and diabetes as factors positively associated, whereas COVID-19 vaccination was negatively associated with severe/critical infection. Following COVID-19 infection, the number of patients with severe/critical COVID-19 who had high RA disease activity and the incidence of flares was significantly higher in comparison to patients with mild/moderate COVID-19 (P < 0.001 and 0.003; respectively). Age > 60years, diabetes, and history of previous serious infections are risk factors for severe/critical COVID-19, while vaccination has a protective role in RA patients. Infection particularly when severe is associated with risk of disease flare.

Demographic, Clinical Profile of Rheumatoid Arthritis Patients and Their Association with Disease Severity in Ghana.

Rheumatoid arthritis (RA) is one of the frequent chronic, systemic, inflammatory autoimmune disorders with an estimated global prevalence of 1%. RA leads to joint destruction and disability if left untreated. Ghana has seen very few studies on RA, and little is known about the disease's severity and related variables. This study sought to characterize the clinical presentation and determine disease severity and associated risk factors with disease severity among RA patients in a tertiary hospital in Ghana. This cross-sectional study was conducted between September 2020 and August 2021. This study included 56 consecutively consenting RA patients from the Komfo Anokye Teaching Hospital orthopaedic unit. Diagnosis of RA was based on the updated American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) 2022 rheumatoid arthritis classification criteria by a rheumatologist. A study questionnaire was used to gather participant demographics and clinical features, and results from the laboratory were taken from the patients' charts and medical records. The patients' disease severity was evaluated based on the rheumatoid arthritis disease activity score, which is based on a 28-joint count (DAS28), and their functioning was evaluated using the modified health assessment questionnaire. The participants' mean age was 51.25 ± 13.22 years. Out of the total participants, 46 were females, and 10 were males (female-to-male ratio 4.6 : 1). Moreover, 37.50% had arthritis of the hand; 5.30% had severe disease, and 94.60% were not severe. A majority (76.80%) were on methotrexate medication. The most frequently involved joints were the knee (42.90%), wrist (32.10%), and elbow (12.50%). There was no statistically significant association with disease severity and a functional status score of >0.5 (cOR: 10.60, 95% CI (0.52-217.30); p = 0.124). In addition, marital status (p = 0.04), disease duration (p = 0.04), family complaints (p = 0.02), and ESR (p = 0.03) were significantly associated with disease severity. RA is predominant among elder populations and females. Disease duration, family complaints, and ESR are associated with disease severity. The findings of this study call for interventions towards ensuring early diagnosis of RA among high-risk populations to enhance good management practices.

Comparison between dual-energy computed tomography and ultrasound in the diagnosis of gout

Objectives: Gout is one of the most common inflammatory arthritic conditions that arise due to the super saturation of urate levels in body tissues, resulting in the formation of monosodium urate (MSU) crystals that get deposited in and around the joints. Clinical diagnosis of gout is generally made based on signs and symptoms. The biochemical diagnosis is based on the levels of serum uric acid. However, hyperuricemia is a weak marker for gout diagnosis. The gold standard for diagnosing gout is the identification of MSU crystals in the synovial fluid by Polaroid microscopy. However, it is an invasive procedure that could lead to complications such as joint effusion and intra-articular hemorrhage. Imaging offers a non-invasive method for the diagnosis of gout. Ultrasound (USG) has emerged as a useful measure for detecting joint effusion and synovitis, studying cartilage, describing early bone erosions, and evaluating tendons and crystal deposition. Dual-energy computed tomography (DECT) is a useful non-invasive technique that helps visualize MSU crystals, along with other soft tissue changes and erosive pathologies, at high resolution, much earlier than conventional radiography could do. Material and Methods: Clinically suspected or diagnosed gout patients in the age group of 20–75 years of both genders attending outpatient services were selected for the study. All the patients fulfilling the inclusion criteria of clinical suspicion of gout or already proven cases of gout were clinically examined, and body mass index, presenting complaints, symptomatic joints, past medical history, family history, and personal habits were noted. The diagnosis of gout was confirmed using the 2015 American college of rheumatology/European league against rheumatism (ACR/EULAR) classification criteria: A cut-off score &gt;8 was considered diagnostic. Thereafter, all the patients underwent ultrasonographic and computed tomography evaluations. All the patient’s assessments were made at nine locations bilaterally – shoulder, neck, wrist, metacarpal, metatarsophalangeal, ankle, hip, knee, and elbow to check for multiple joint involvements. All the DECT images were post-processed, allowing analysis of images using the three material decomposition methods. On reconstructed DECT images, green color-coded MSU crystals were considered suggestive of gout. Results: The present study reported a higher detection of gout on DECT (97.1%) as compared to the USG (88.2%). Similarly, several studies reported a higher detection rate of MSU crystal deposition by DECT as compared to the detection of the double-contour sign by USG. This study reported sensitivity, specificity, positive predictive, and negative predictive value (PPV and NPV) of USG as 91%, 92%, 95%, and 85%, respectively. In contrast, DECT’s sensitivity, specificity, PPV, and NPVs were 96%, 100%, 100%, and 92%, respectively. DECT showed to have a high sensitivity as well as specificity. Conclusion: The study showed that DECT is more sensitive and had a better PPV and accuracy than USG in the diagnosis of gout. Keeping in view the high efficacy of DECT in diagnosing gouty joints, it is a strong candidate to emerge as a non-invasive imaging modality of choice for diagnosing gout.

Exploratory clinical subgroup clustering in systemic sclerosis: Results from the Indian Progressive Systemic Sclerosis Registry

Objective: To conduct an exploratory cluster analysis of systemic sclerosis patients from the baseline data of the Indian systemic sclerosis registry. Methods: Patients satisfying American College of Rheumatology-European League Against Rheumatism classification criteria for systemic sclerosis were included. The clusters formed using clinical and immunological parameters were compared. Results: Of the 564 systemic sclerosis registry participants, 404 patients were included. We derived four clusters of which three were anti-topoisomerase I predominant and one was anti-centromere antibody 2 dominant. Cluster 1 ( n-82 (20.3%)) had diffuse cutaneous systemic sclerosis patients with the most severe skin disease, anti-topoisomerase I positivity, males, younger age of onset and high prevalence of musculoskeletal, vasculopathic and gastrointestinal features. Cluster 2 ( n-141 (34.9%)) was also diffuse cutaneous systemic sclerosis and anti-topoisomerase I predominant but with less severe skin phenotype than cluster 1 and a lesser prevalence of musculoskeletal, vasculopathic and gastrointestinal features. Cluster 3 ( n-119 (29.5%)) had limited cutaneous systemic sclerosis patients with anti-topoisomerase I positivity along with other antibodies. The proximal muscle weakness was higher and digital pitting scars were lower, while other organ involvement was similar between clusters 2 and 3. Cluster 4 ( n-62 (15.30%)) was the least severe group with limited cutaneous systemic sclerosis and anti-centromere antibody predominance. Age of onset was higher with low musculoskeletal disease and a higher presence of upper gastrointestinal features. The prevalence of interstitial lung disease was similar in the three anti-topoisomerase I predominant clusters. Conclusion: With exploratory cluster analysis, we confirmed the possibility of subclassification of systemic sclerosis along a spectrum based on clinical and immunological characteristics. We also corroborated the presence of anti-topoisomerase I in limited cutaneous systemic sclerosis and the association of interstitial lung disease with anti-topoisomerase I.

Ayurvedic intervention in the management of Amavata (Rheumatoid Arthritis): A Case Series

The present case series documents the successful management of five cases of confirmed Amavata (Rheumatoid Arthritis). A retrospective analysis of five patients with Rheumatoid Arthritis (RA) symptoms was conducted in this study at the Arogyashala Rugnalaya Panchavati Nashik, Maharashtra. The patients were between the age of 39 to 70 years, were diagnosed as RA positive through a blood investigation, in July-August 2023, and were managed through Ayurveda interventions. The interventions include Anshanrupi Langhana (Fasting), Sunthisiddha Jala (Medicated water) in a dosage of 250-500 ml a day, Ruksha Waluka Pottali Swedana (Dry steam), and Shothahara Lepa (Medicinal paste) were prescribed for five days. Symptomatic assessment was done every day and blood investigations were conducted after 5 days. Significant relief in all the cases was observed as per RA classification criteria 2010 and DAS28-P index scores. However, large-scale randomized controlled trials are required to further validate the same.

Cachexia Prevalence in a Population of Moroccan Women with Rheumatoid Arthritis.

To assess body composition in women with rheumatoid arthritis (RA) compared to healthy controls, to calculate the prevalence of rheumatoid Cachexia (RC), and to identify the associated factors. We conducted a case-control study on 112 female patients with RA according to the 2010 American College of Rheumatology/European League Against Rheumatism classification criteria for RA; and 224 age-matched healthy women. Body composition (BC) and bone mineral density (BMD) scans were obtained using Dual-energy X-ray absorptiometry (DXA). RC was defined by a fat-free mass index (FFMI) below the 10th percentile and a fat mass index (FMI) above the 25th percentile compared with the control group. We conducted a comparison between RA patients and healthy controls then a multiple regression analysis was conducted where the dependant variable is the presence of RC. RC prevalence was 42.85% while the mean body mass index (BMI) was the same in both groups. RA patients had a higher FM and lower FFM comparing to healthy controls. In our population, 78.60% of patients were on methotrexate and 12.50% on anti TNF therapy. Comparison between patients with and without RC showed that patients with RC have a higher proportion of erosive arthritis and of active disease. Regression logistic analysis showed that RC was significantly associated to erosive arthritis and active disease (OR at 33.31 (8.42-131.70) and 8.98 (1.64-49.20) respectively), independently of age, erythrocyte sedimentation rate, C-reactive protein, disease duration, steroid cumulative dose and biologic Disease-Modifying Anti-Rheumatic Drugs(bDMARDs) use. Our study showed that almost half of our RA patients have RC, even with a high BMI.

Association of serum chemerin levels with complications and comorbidity in rheumatoid arthritis

Introduction. Rheumatoid arthritis (RA) is a systemic autoimmune disease as well as a typical inflammatory process. Chemerin is a fat tissue cytokine, which specific receptors were discovered on the surface of the innate immune cells. It is of interest to study the association of chemerin with the complications and comorbidity in RA.Aim. To study the association between serum chemerin levels with complications and comorbidity in rheumatoid arthritis.Materials and methods. 88 women with RA were enrolled in our study. ll patients undergone standard clinical and laboratory examination. Serum chemerin, high-sensitive C-reactive protein (hsCRP), anti-citrullinated protein antibodies, insulin and C-peptide levels were determined using ELISA. X-ray absorptiometry was performed. Statistical analysis was performed using conventional methods with a software package Statistica 10.0.Results. Median chemerin concentration was 463.5 [366–576.5] ng/ml. Chemerin concentration correlated with the age (ρ = 0.232; р = 0.030), weight (ρ = 0.254; р = 0.017) and body mass index (BMI) (ρ = 0.212; р = 0.047), but wasn’t associated with the RA classification criteria. Positive correlation between chemerin concentration and number of painful joints (NPJ) (ρ = 0.213; р = 0.046) and hsCRP (ρ = 0.273; р = 0.010) was observed. Patients with type 2 diabetes mellitus (DM2) had higher chemerin concentration (598.0 ng/ml vs 479.5 ng/ml, Z = -2.68; p = 0.007) and patients with cholecystectomy in anamesis had lower (359.0 ng/ml vs 479.0 ng/ml, Z = 2.02; p = 0.043). Chemerin concentration correlated with systolic and diastolic blood pressure (BP) (ρ = -0.41; р &lt; 0.001 and ρ = -0.27; р = 0.028, respectively).Conclusions. Chemerin concentration in women with RA correlates with age, weight, BMI, NPJ and hsCRP. Chemerin concentration in patients with comorbid DM2 was higher and in patients comorbid with cholecystectomy in anamnesis was lower. Chemerin concentration correlates negatively with a systolic and diastolic BP.

Evaluation of the Salivary Oxidative Stress, and Non-Enzymatic Antioxidants Marker in Patients with Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic systemic inflammatory autoimmune disease that preferentially affects diarthrodial joints. Oxidative stress is elevated in RA patients implying reactive oxygen species (ROS) are possible mediators of tissue damage. Assess the level of total antioxidant capacity (TAC), malondialdehyde (MDA), and non-enzymatic antioxidants (vitamin E, and C )in the saliva of in patients with rheumatoid arthritis(RA). For the realization of our goals we included sixty rheumatoid arthritis patients (RA) (21 female and 39 male) who were fulfilling the American College of Rheumatology and European League Against Rheumatism 2010 revised criteria for classification of RA ,picked randomly, at the age from 25-57 years, and 60 as age matched control group, who attended to Tikrit Teaching Hospital / Tikrit / Iraq during the period from January 2017 to March 2018. Stimulated saliva specimens were collected at the morning. TAC of saliva was evaluated by spectrophotometric assay. Statistical comparisons were performed using Student’s t-test, by SPSS 13. Levels of salivary pH, flow rate, TAC, vit E and C were decreased significantly, whereas the salivary level of MDA were increased significantly in RA patients when compared with healthy controls. There was an increased oxidative stress and a low antioxidant status in patients with RA. These changes are probably due to efforts for reducing lipid peroxidation and hence to lower tissue damage.

Vasculitis distribution and clinical characteristics in giant cell arteritis: a retrospective study using the new 2022 ACR/EULAR classification criteria.

Giant cell arteritis (GCA) is the most common vasculitis of the elderly. In recent years, advanced imaging has to a certain extent replaced temporal artery biopsy (TAB) to aid diagnosis in many institutions and helped to identify three major phenotypes of GCA, namely, cranial GCA (c-GCA), large-vessel non-cranial GCA (LV-GCA), and a combination of these two patterns called mixed-GCA, which all show different clinical patterns. Recent 2022 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria respect the changing conception and clinical practice during the last two decades. In this cohort study, we present vasculitis distribution and baseline characteristics using the 2022 ACR/EULAR classification criteria as well as the EULAR core data set. In this retrospective study from Southern Norway, we identified all patients diagnosed with GCA between 2006 and 2019 in our single-center fast-track clinic (FTC). We included all patients who were examined using ultrasound (US) of cranial as well as non-cranial large vessels at diagnosis to depict vascular distribution. EULAR core data set, ACR 1990, and 2022 ACR/EULAR classification criteria were used to characterize the cohort. Seventy-seven patients were diagnosed with GCA at our institution in the aforementioned period. Seventy-one patients (92.2%) were diagnosed with the help of US and included in the further analysis. The 2022 ACR/EULAR classification criteria allocated 69 patients (97.2%), while the ACR 1990 classification criteria allocated 49 patients (69.0%) in our cohort as having GCA. Mixed-GCA was the most common type in 33 patients (46.5%). Weight loss was significantly more common in patients with large-vessel non-cranial vasculitis in LV-GCA and mixed-GCA. Headache, on the other hand, was significantly more common in patients with involvement of cranial vessels. Mixed GCA was the most common form of GCA in our cohort. In our study, the 2022 ACR/EULAR classification criteria seem to be a more useful tool compared with the old ACR 1990 classification criteria to allocate GCA patients diagnosed and treated at our US-based FTC as having GCA.

Non-contact meibography changes according to disease activity in rheumatoid arthritis cases

Abstract Purpose To measure dry eye disease (DED) activity in rheumatoid arthritis (RA) patients, correlate it with the activity and duration of RA, and objectively measure the degree extent of DED in RA active cases. Methods The paper studied the meibomian gland of 30 RA cases referred by the Rheumatology Department, Sohag University Hospitals to Sohag Cornea and Refractive Center, Sohag, Egypt, by infrared non-contact meibography in the Scheimpflug topographer (Sirius, CSO, Italy) from July 2021 to July 2022. The cases fulfilled the RA classification criteria according to the 2010 American College of Rheumatology and European League and underwent full lab investigations. They were distributed to two groups based on the DAS-28 questionnaire. The patients were distributed into low to moderate activity (3.2 &lt; score &lt; = 5.1) and high activity groups (score &gt; 5.1). Results This study included 60 eyes of 30 RA patients. They scored a mean age of (44 ± 10 years), number of swollen joints (3 ± 3), number of tender joints (5 ± 3), duration of disease (8 ± 4), activity of the disease measured by DAS-28 (4.4 ± 0.9), and sex (males were 9.7% vs females 90.3%). The number of swollen joints, tender joints, ESR and DAS-28 were more in the high activity group with the p-value of (0.018, 0.001, &lt; 0.003 and &lt; 0.004), respectively. There are no statistically significant differences between both groups as regards disease duration (p-value of 3.8). The high activity group showed significant affection regarding the mebioscore of the lower and upper lids, total mebioscore, percentage of meibomian glands in upper and lower lids, first non-invasive break-up time test (NIV-BUT) of the tear film, as well as average non-invasive break-up time test (NIavg-BUT). There were moderate correlations between the activity of the disease represented by (DAS-28) and different parameters evaluating eye dryness (meiboscore of the lower and upper lids, total meiboscore, percentage of meibomian glands in upper and lower lids, NIV-BUT of the tear film, and NIavg-BUT of the tear film). Conclusion There was no correlation with duration of RA but moderate correlations between the activity of the disease represented by (DAS-28) and different parameters evaluating eye dryness in RA patients with valuable use of noncontact Meibography to evaluate eye dryness in RA cases. Both Meiboscore and Meiboscale of Non-contact Meibography were found to be useful tools in grading of dry eye disease in different activity grades of Rheumatoid Arthritis.
