Assessment of IL-1β, IL-6, TNF-α, IL-8, and CCL 5 levels in newly diagnosed Saudi patients with rheumatoid arthritis. Int J Rheum Dis 2022; 25:1013-1019. [PMID: 35748059 DOI: 10.1111/1756-185x.14373] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 06/03/2022] [Accepted: 06/11/2022] [Indexed: 02/06/2023]
Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic systemic inflammatory disorder which mainly affects small joints, occurs most commonly in middle-aged adults, and can be fatal in severe cases. The exact etiology of RA remains unknown. However, uncontrolled expression of pro-inflammatory cytokines and chemokines can contribute to the pathogenesis of RA. AIM In the current study, we assessed the potential of serum concentrations of interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, IL-8, and C-C motif chemokine ligand (CCL)5 as early predictive markers for RA. METHODS In addition to clinical examination, blood samples were collected from 100 Saudi patients recently diagnosed with early RA for basic and serological tests, including rheumatoid factor (RF), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR). Sera of 32 healthy individuals were used as controls. Specific enzyme-linked immunosorbent assay was used to quantify the serum IL-1β, IL-6, TNF-α, IL-8, and CCL5 levels in the samples. RESULTS Our results indicated that RF, CRP, and ESR levels were higher in RA patients compared to controls. Furthermore, serum levels of IL-1β, IL-6, IL-8, and CCL5, but not TNF-α, significantly increased in RA patients compared to controls. CONCLUSION Overall, the findings suggested that IL-1β, IL-6, IL-8, and CCL5 can be used as biomarkers in the early diagnosis of RA.

Demographic and Clinical Patterns of Rheumatoid Arthritis in an Emirati Cohort from United Arab Emirates. Int J Rheumatol 2019; 2019:3057578. [PMID: 31662761 PMCID: PMC6778867 DOI: 10.1155/2019/3057578] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2019] [Revised: 07/22/2019] [Accepted: 08/01/2019] [Indexed: 01/09/2023] Open
Abstract
This retrospective cohort study aimed to assess the demographic and clinical characteristics of rheumatoid arthritis (RA) in Emirati patients attending Cleveland Clinic Abu Dhabi, a large tertiary center in the Middle East. In this study, 414 Emirati patients with RA were evaluated over a 3-year period from April 2015 to April 2018. All patients fulfilled the 2010 RA ACR/EULAR criteria and were assessed for demographic and clinical characteristics. The estimated RA prevalence rate in our population cohort was 2.72%. Females showed predominance (80%) with a higher body mass index (31.4 ± 6.61, P = 0.0001) compared to males (28.8 ± 6.03, P = 0.0001). The most frequent comorbidity observed was dyslipidemia (43.5%) followed by hypertension (37.9%), diabetes mellitus (34.5%), and gastroesophageal reflux disease (33.1%). Xerophthalmia was the most frequent extra-articular manifestation. Rheumatoid factor and anti-citrullinated peptide were detected in 63.3% and 41.5% patients, respectively, while both were present in 33.3% of patients. Methotrexate, adalimumab, and rituximab were the most frequently prescribed disease modifying agents. In this study, we describe disease features that are unique to United Arab Emirates (UAE) patients and demonstrate that RA has a significant disease burden. Our findings highlight the need for a RA national registry to improve the quality of care of these patients in UAE.

Abstract
Objective This study assessed the mode of application (oral, intravenous or subcutaneous (SC)) currently employed in the treatment of rheumatoid arthritis (RA) in patients from Qatar in comparison with patients' individual preferences for the mode of application of their treatment. Methods This study included 294 RA patients visiting three clinics at the main referral hospital in Qatar who were interviewed using a standard questionnaire to determine their preference of mode of application for their disease-modifying antirheumatic drug (DMARD) treatment in relation to their currently employed mode of application. Results The majority of patients were female (76%), and 93% of male patients and 61% of female patients in the study clinics were of a nationality other than Qatari. The highest patient preference recorded was for an oral therapy (69%), compared with injection (23%) and intravenous (8%) therapy. In total, 85% of patients expressed a preference to remain on oral therapy compared with 63% and 58% of intravenous and SC injection patients indicating a preference to remain on their current method of administration. Conclusions This high preference for oral therapies highlights the considerable need for incorporation of new oral targeted synthetic DMARD therapies into clinical practice within the region.

Abstract
OBJECTIVES To describe the prevalence of rheumatoid nodules (RN) in patients with rheumatoid arthritis (RA) and to compare their features with those of patients without RN. SUBJECTS AND METHODS Adult RA patients (n = 952) in the Kuwait Registry for Rheumatic Diseases from February 2013 to December 2015 were evaluated for RN. Demographic and serological features and disease activity and severity were obtained from the registry. RESULTS Of the 952 RA patients, 22 (2.3%) had RN and 930 (97.7%) did not. Age, sex, disease duration, smoking, and family history of an autoimmune rheumatic disease were similar. Obesity was more prevalent in the RN group, i.e. 11 (50%) vs. 326 (35.1%), p = 0.016. There was no difference in rheumatoid factor (RF) or anti-cyclic citrullinated peptide antibody positivity. Patients with RN had more sicca symptoms, i.e. 8 (36.4%) vs. 152 (16.3%), p = 0.025, a higher mean score on the visual analogue scale pain (3 ± 2.9 vs. 2 ± 2.7, p < 0.001), more tender joints (6.4 ± 8.8 vs. 4.2 ± 7.2, p = 0.001), a higher patient global assessment of disease activity (3.3 ± 2.7 vs. 2.3 ± 2.7, p < 0.001), and more deformities, i.e. 3 (13.6%) vs. 74 (8%), p = 0.034. The mean health assessment questionnaire score in RN patients was 1.1 versus 0.9 in patients without RN (p = 0.08). Patients with RN had a low disease activity (means: disease activity score [DAS-28], 3.02; clinical disease activity index, 7.7; and simple disease activity index, 10.4), similar to the other group. While the rates of methotrexate treatment were comparable, biologic therapy was administered more in patients with RN (i.e. 15 [68.2%] vs. 478 [51.4%], p < 0.001). CONCLUSION In Kuwait, the prevalence of RN is low among RA patients. Patients with and without RN are similar in terms of demographics and serologic features, except for more obesity. However, patients with RN have more sicca symptoms, joint deformities, and painful and tender joints. Disease activity scores are low with more frequent biologic therapy.

Abstract
INTRODUCTION Brazilian epidemiological studies on rheumatoid arthritis are scarce, mainly in the northeast; thus many data currently available originate from the international literature. OBJECTIVES To describe demographic, clinical and serological characteristics of patients with rheumatoid arthritis (RA) followed-up by the same physician, in state of Piauí, Brazil. PATIENTS AND METHODS Data were collected between August 2010 and March 2013, in three health services of Piauí that provided health care in Rheumatology: a university-affiliated hospital, a public outpatient clinic and a private clinic. RESULTS The numbers represent mean ± SD or percentage: 47.5±11.03 years-old non-Caucasian woman, non-smoker (59.2%), low educational level, mean disease duration of 7.7 years ± 7.6, and major extra-articular manifestations were rheumatoid nodules (19.4%) and sicca syndrome (46.9%). CONCLUSION Features of rheumatoid arthritis obtained in this study are similar to those found in some national and international studies, but we observed higher female preponderance and illiteracy rate, in addition to a moderately severe erosive disease on average, with frequent sicca and other extra-articular manifestations.

Abstract
OBJECTIVE To describe the clinical characteristics, serologic, radiological and clinical disease activity, and modality of therapy in patients with rheumatoid arthritis (RA) at tertiary outpatient care in Qatar. METHODS The study design was cross-sectional where 100 consecutive cases who met 1987 American College of Rheumatology criteria for diagnosis of RA were enrolled in this study. Demographic data (sex, nationality and age) numbers of swollen and tender joints, X-rays and current medications were collected during outpatients visits to Hamad General Hospital. Disease Activity Score of 28 joints (DAS28) and Health Assessment Questionnaires (HAQ) scores were calculated. All patients with RA who were seen as rheumatology outpatients were invited to participate in the study. RESULTS One hundred patients were seen and examined during their follow-up at the outpatient clinic; data were collected and analyzed. Females represented 67% of all patients, 6% had more than six swollen joints, 9% had more than six tender joints. DAS28 and erythrocyte sedimentation rate (DAS28) calculation revealed 49% of patients were in remission (DAS28 < 2.6), 15% had low disease activity (DAS28 2.6-3.2) and 36% had DAS28 > 3.2.Mean HAQ score was 1.02. Rheumatoid factor (RF) was positive in 63%, while anti-cyclic citrullinated protein antibody (anti-CCP) was positive in 71%, and 49% were positive for both. Radiography of hands and feet during the previous year was done in 65% of patients: 11% of them had erosions. Sixty-six percent were on one synthetic disease-modifying anti-rheumatic drug (DMARD) and 27% where on more than one synthetic DMARD and 7% where on no DMRD. Glucocorticoids were used in 51% and 29% were on biologics. CONCLUSION Sixty-four percent of rheumatoid arthritis patients in Qatar were in remission or had low disease activity while the remaining 36% had active disease and among these patients 29% were on biologics.

Abstract
OBJECTIVES To determine the spectrum and expression of rheumatoid arthritis (RA) in patients attending the rheumatology clinic in Nizwa hospital, Oman. METHODS SUBJECTS AND METHODS 66 patients fulfilling the American College of Rheumatology (ACR) criteria for the diagnosis of RA were included in the study. The patients were either attending for the first time or were already diagnosed and attending for follow up. The demographic, clinical, laboratory and radiological findings are reported. RESULTS Of the 66 patients studied, 16 were males and 50 were females. The mean age of patients at onset was 44.5 ±14.5 years, and the females were younger than males at presentation. 38 (57.57%) were seropositive and two (3.03%) only had rheumatoid nodules. The majority of the patients were considered as class 1 or 2 according to the ACR functional classification. The commonest extra-articular manifestation was anaemia (27.27%) followed by keratoconjuctivitis sicca (24.42%). The upper limb joints were affected more than the lower limbs and the most commonly involved joint was the wrist (81%) followed by the metacarpophalangeal (MCP) (66.66%) joints, the knee (57.57%), ankle (45.45%), elbow (42.42%), shoulder (42.42%), and the proximal interphalangeal (PIP) (36.36%) joints. The main associated diseases were hypertension (21%), ischemic heart disease (13.63%) and diabetes mellitus (9.03%). Systemic features were predominantly morning stiffness (84.5%) and fatigue (45.45%). Reported deaths were due to sepsis and cardiac arrhythmia. Thus 63 (95.45%) of the patients were on conventional disease modifying antirheumatic drugs. CONCLUSIONS Demographic characteristics were similar to those reported by others, the seropositivity rate and nodular form of the disease was less in the studied patients and the disease seemed milder than that reported in western countries.

Abstract
Studies have shown that patients with rheumatoid arthritis (RA) in the Middle East have delayed diagnosis and low disease-modifying anti-rheumatic drug (DMARD) utilization. We describe the characteristics and treatments of consecutive RA patients presenting to a new musculoskeletal clinic in Dubai, United Arab Emirates (UAE). Demographic and clinical data were collected over a 10-month period at the first visit to our clinic for patients meeting the American College of Rheumatology (ACR) criteria for RA. A total of 100 patients were seen: (average +/- SD) age 42.2 +/- 12.3 years; female 87%; Arabs 38%, Indian 36%, Caucasian and others 26%; 73% rheumatoid-factor positive; years since diagnosis: 3.9 +/- 5.7; lag time between symptom onset to diagnosis 1.2 +/- 1.3 years and lag time to first DMARD was 1.6 +/- 2.0 years. Mean tender joint count was 8.9 +/- 7.9, mean swollen joint count 9.0 +/- 7.6, mean patient's global assessment of disease activity 57.4 +/- 25.0 mm, mean ESR 33 +/- 25 mm/h, mean DAS28 5.2 +/- 1.6, physician global assessment 55.0 +/- 23.8. Only 43% were on DMARDs (25% MTX, 5% TNF blockers). Among the patients who were not on DMARD, only 28.1% had disease duration less than 1 year (p = <0.01). Erosions were present in 55.2% of patients with available X-rays, and deformities in 26% of patients. There were no racial differences in disease characteristics. The UAE has a unique population with many races residing in the country. Among the first 100 consecutive patients seen at our clinic, there were no significant differences in disease characteristics with the majority of the patients having very active disease, delayed diagnosis, and not being treated with DMARDs.

Abstract
Association between HLA-DRB1 alleles and rheumatoid arthritis (RA) has been known for more than three decades. However, the strength of these links varies between ethnic groups. This study examines the frequency of HLA-DRB1 alleles amongst Saudi RA patients. The DRB1 region of major histocompatibility complex was screened by polymerase chain reaction/sequence specific primers (PCR/SSP) in a total of 140 subjects including 70 RA patients and 70 matched healthy controls. HLA-DRB1 *04 was found to be the most frequent allele associated with RA followed by DRB1 *08 and DRB1 *10. On the other hand, the frequency of DRB1*06 was found to be decreased in RA patients as compared to controls. Molecular sub typing of the most prevalent allele DRB1 *04 revealed a statistically significant association between RA and DRB1 *0405. We conclude that an improved understanding about the influence of HLA on RA might help in predicting the susceptibility or protection against disease.

Abstract
BACKGROUND The specific aim of our study was neither prognosis nor long-term evaluation but focus on determining incidence of rheumatoid nodules (RN) in a large population of patients with rheumatoid arthritis (RA) on the coastline of Croatia (Dalmatia) within a certain range. We compared our data with those published previously in the literature. METHODS Our study was focused on determining incidence of RN occurrence in patients with rheumatoid arthritis in Dalmatia, Croatia by comparing these figures with data reported elsewhere and evaluating its importance in the process of diagnosing RA. The duration of the study was 10 years (1991-2001). There were 421 patients (344 women and 77 men) with confirmed RA diagnosis. Median follow-up time was 2 years (range: 1.4-3.5 years). RESULTS Existence of RN was established by clinical examination in 109 of 421 patients; incidence density was 17.3%. RN occurred somewhat more frequently in men (32%) as compared to women (24%) without statistically significant difference. In 38% of patients, RN occurred simultaneously in several sites, more frequently in men (64%) than in women (30%) (odds ratio [OR] 2.13, p <0.05). Correlation of seropositivity and RN appearance was very high: positive in 84% of patients with nodules as compared to 58% of patients without nodules (OR 1.45, p <0.05) with no statistically significant differences between sexes. CONCLUSIONS Results obtained warrant the conclusion that RN incidence in our patients from Dalmatia is comparable with results of earlier Croatian studies as well as with Western European figures and Caucasian population data reported on other continents. RN incidence differs significantly for Asian and Arabian populations, i.e., is less frequent, and for the U.S. population, where it is more frequent.
