The Saudi consensus recommendations for the management of psoriatic arthritis (2023).

Psoriatic arthritis (PsA) is a complex inflammatory disease characterized by musculoskeletal and non-musculoskeletal manifestations. It is a distinct disease entity at the interface between rheumatology and dermatology, making it challenging to manage. The diverse clinical presentation and severity of PsA require a multidisciplinary approach for optimal care. Early diagnosis and management are necessary to improving quality of life for patients. In Saudi Arabia, there is currently no unified national consensus on the best practices for managing PsA. This lack of consensus leads to debate and uncertainty in the treatment of the disease, resulting in over or under prescribing of biological agents. To address this issue, a multidisciplinary work group was formed by the Saudi Ministry of Health. This group, consisting of dermatologists, rheumatologists, and pharmacists, aimed to develop evidence-based consensus recommendations for he use and monitoring of biological therapy in PsA management. The work group conducted five consensus workshops between December 2021 to March 2022. Using the nominal group technique, they discussed various aspects of PsA management, including eligibility criteria for biological treatment, monitoring of disease activity, treatment goals, screening, precautions, and management of PsA with biologic therapies. The group also considered special considerations for patients with comorbidities, pregnant and lactating women, as well as pediatric and adolescent populations. The resulting consensus document provides recommendations that are applicable to the Saudi setting, taking into account international guidelines and the specific needs of PsA patients in the country. The consensus document will be regularly updated to incorporate new data and therapeutic agents as they become available. Key Points • In Saudi Arabia, there is a lack of unified national consensus on the optimal management of PsA, therefore, this article aims to provide up-to-date evidence-based consensus recommendations for the optimal use and monitoring of biologic therapy in the management of PsA in Saudi Arabia. • The consensus development process was undertaken by a multidisciplinary work group of 13 experts, including two dermatologists, six rheumatologists, and five pharmacists. • There is more than one disease activity tool used in PsA disease, depending on the disease domain - peripheral arthritis Disease Activity Index in Psoriatic Arthritis (DAPSA) or Minimal Disease Activity (MDA), axial PsA Ankylosing Spondylitis Disease Activity Score (ASDAS), and dactylitis and enthesitis MDA. • The main goal of therapy in all patients with PsA is to achieve the target of remission, or alternatively, low disease activity in all disease domains and improve quality of life (QoL).

The Fidelity of Rheumatoid Arthritis Multivariate Diagnostic Biomarkers Using Discriminant Analysis and Binary Logistic Regression.

Rheumatoid arthritis (RA) is an autoimmune inflammatory disease that causes multi-articular synovitis. The illness is characterized by worsening inflammatory synovitis, which causes joint swelling and pain. Synovitis erodes articular cartilage and marginal bone, resulting in joint deterioration. This bone injury is expected to be permanent. Cytokines play a prominent role in the etiology of RA and could be useful as early diagnostic biomarkers. This research was carried out at Riyadh's King Khalid University Hospital (KKUH). Patients were enrolled from the Rheumatology unit. Seventy-eight RA patients were recruited (67 (85.9%) females and 11 (14.1%) males). Patients were selected for participation by convenience sampling. Demographic data were collected, and disease activity measurements at 28 joints were recorded using the disease activity score (DAS-28). Age- and sex-matched controls from the general population were included in the study. A panel of 27 cytokines, chemokines, and growth factors was determined in patient and control sera. Binary logistic regression (BLR) and discriminant analysis (DA) were used to analyze the data. We show that multiple cytokine biomarker profiles successfully distinguished RA patients from healthy controls. IL-17, IL-4, and RANTES were among the most predictive variables and were the only biomarkers incorporated into both BLR and DA predictive models for pooled participants (men and women). In the women-only models, the significant cytokines incorporated in the model were IL-4, IL-17, MIP-1b, and RANTES for the BLR model and IL-4, IL-1Ra, GM-CSF, IL-17, and eotaxin for the DA model. The BLR and DA men-only models contained one cytokine each, eotaxin for BLR and platelet-derived growth factor-bb (PDGF-BB) for DA. We show that BLR has a higher fidelity in identifying RA patients than DA. We also found that the use of gender-specific models marginally improves detection fidelity, indicating a possible benefit in clinical diagnosis. More research is needed to determine whether this conclusion will hold true in various and larger patient populations.

Single Nucleotide Polymorphisms Associated with Rheumatoid Arthritis in Saudi Patients.

Rheumatoid arthritis (RA) is a complex, multifactorial disorder with an autoimmune etiology. RA is highly heritable and is associated with both human leucocyte antigen (HLA) and non-HLA genes. We investigated the associations of 33 single nucleotide polymorphisms (SNPs) with RA in the Saudi population. METHODS: This study included 105 patients with RA and an equal number of age- and sex-matched controls. The patients with RA attended outpatient clinics at King Khalid University Hospital in Riyadh, Saudi Arabia. Blood samples were collected, and DNA was extracted using Qiagen kits. Primers were designed for the 33 selected SNPs using the MassEXTEND primers program, and samples were genotyped on the Sequenom MassARRAY iPLEX platform. The allele frequencies and genotypes were determined for each SNP, and the results obtained for the patients were compared to those for the controls. RESULTS: The allele and genotype frequencies of six SNPs were significantly associated with RA: rs1188934, rs10919563, rs3087243, rs1980422, rs10499194, and rs629326. The minor alleles of rs1188934, rs10919563, rs10499194, and rs629326 were protective, with odds ratios of 0.542, 0.597, 0.589, and 0.625, and p-values of 0.002, 0.023, 0.013 and 0.036, respectively. In addition, the heterozygote frequencies of two SNPs (rs6859219 and rs11586238) were significantly higher in the controls than in the patients. CONCLUSIONS: There is considerable heterogeneity in the genetics of RA in different populations, and the SNPs that are associated with RA in some populations are not in others. We studied 33 SNPs and only eight were associated with RA. The remaining SNPs showed no allelic or genotypic associations with RA.

Functional and psychosocial impact of COVID-19 pandemic on rheumatic patients' quality of life in Saudi Arabia.

PURPOSE: The COVID-19 pandemic might add to the stressors experienced by people living with rheumatic diseases. This study aimed to examine rheumatic patients' functional and psychosocial states during the pandemic and assess its impact on their quality of life. METHODS: Our time-series study included a patient-centered electronic survey, sampling adult rheumatic patients living in Saudi Arabia at different time points from March to August 2020. Patient-reported outcomes included physical function, anxiety, depression, fatigue, sleep disturbance, ability to participate in social roles, and pain interference domains were measured using the Patient-Reported Outcomes Measurement Information System (PROMIS-29 Profile v2.1). RESULTS: A total of 1278 respondents were enrolled. Results showed significant variation in patients' experiences. Our analyses revealed that the physical well-being of rheumatic patients was significantly impacted, and such effect was persistent over time irrespective of public health measures to control the COVID-19 outbreak. CONCLUSION: Our findings consistently demonstrated the need for psychological and social consideration to improve rheumatic patients' quality of life. Nevertheless, there is still a lot to be learned about the extent of COVID-19 impact on rheumatic patients and the implications it has on long-term disease outcomes.

National systemic lupus erythematosus prospective cohort in Saudi Arabia: A study protocol.

ABSTRACT: Systemic Lupus erythematosus (SLE) is a chronic multisystem, multifactorial inflammatory autoimmune disease. The SLE patients have 3 times increased risk of mortality based on international data with ethnicity playing an important impact on patients' morbidity and mortality. Descriptive studies from Saudi Arabia showed variation in clinical features from one region to another. Moreover, reliable inference from these studies is limited by study methodology and lack of translational data using biological samples to understand clinical phenotypes of Saudi SLE patients.The aim of this report is to describe the prospective study protocol of the National Systemic Lupus Erythematosus Cohort in Saudi Arabia. The purpose of this cohort study is multifold: first, to examine clinical characteristics and molecular phenotypes of Saudi SLE patients in relation to local environment and practices/lifestyles; second, to assess long-term outcomes of SLE in Saudi population and factors that influence favorable outcomes; third, to compare the effectiveness of various treatment regimens in Saudi SLE population.This study is a longitudinal prospective cohort study of adult, Saudi SLE patients using open cohort study design. Primary outcomes include disease-related outcomes (activity, improvement, and organ damage) and patient-reported outcomes (quality of life). Secondary outcomes include physiological and molecular modifications associated with changes in disease activity states.Results and analysis are in on-going study.This study provides a source of reliable data for clinical and translational research. This will allow us to have a holistic approach to SLE pathogenesis especially in Saudi population and may take us a step further toward much more personalized medicine.This protocol has been registered in NIH ClinicalTrial.gov (ClinicalTrial.gov identifier: NCT04604990) on October 27, 2020.

Cross-Cultural Validation of the 5-Item Compliance Questionnaire for Rheumatology to the Arabic Language in Patients with Rheumatoid Arthritis.

PURPOSE: A simple measure to assess drug adherence in Saudi patients with rheumatoid arthritis (RA) is required. The aim of this study was to translate and validate the 5-Item Compliance Questionnaire for Rheumatology (CQR5) into Arabic. PATIENTS AND METHODS: The questionnaire was translated and culturally adapted to Arab patients in six steps: initial translation, synthesis of the translation, back translation, expert committee review, test of the pre-final version, and development of the Arabic CQR5 (ACQR-5). The resulting version was tested for validity in patients with RA. RESULTS: A total of 103 adult patients with RA were recruited from rheumatology clinics at a university hospital in Riyadh, Saudi Arabia. After extensive translation, the final tool (CQR) was piloted in 15 patients. The final validation was performed with 88 patients. Of these, 80 (90.9%) were female and 43.2% were seropositive. The mean (±SD) age and disease duration were 50 (±13) and 11.4 (±8.2) years, respectively. Cronbach's alpha reliability was 0.886, and the Kaiser-Meyer-Olkin measure of sampling adequacy for factor analysis was 0.870 (p<0.001). The mean ACQR-5 was 17.78 (2.70), with 14 (15.9%) classified as low adherents and the remaining 74 (84.1%) as high adherents. Binary logistic regression revealed that increasing age (odds ratio [OR] 1.082, 95% confidence interval [CI]: 1.025-1.142, p=0.005) and a trend toward the presence of other comorbidities (OR 3.111, 95% CI: 0.961-10.070, p=0.058) were associated with low adherence. CONCLUSION: ACQR-5 is a simple and feasible tool for identifying adherence levels in patients with RA in Saudi Arabia. A high level of adherence was observed in this study. Additional studies are required to assess ACQR-5 validity and adherence levels in a larger, more diverse population.

Impact of COVID-19 outbreak on rheumatic patients' perceptions and behaviors: A cross-sectional study.

AIM: The dynamics of coronavirus disease 2019 (COVID-19) pandemic has become of special concern to the rheumatology community. Rheumatic patients are required to engage in effective health management but their behavior is often influenced by intrinsic and extrinsic factors. This cross-sectional study aims to examine patients' experiences during the current pandemic and its implication on their health perception and behavior. METHOD: A patient-centered electronic survey was used, randomly sampling rheumatic patients in Saudi Arabia during March and April 2020. Questions included patients' socio-demographics, diseases, medications, COVID-19 knowledge, source of information, fear level, disease activity perception, health care utilization, medication accessibility, and therapeutic compliance (measured using a modified version of Medication Adherence Reporting Scale). Correlation and regression coefficients were used to evaluate associations among the aforementioned variables. RESULTS: A total of 637 respondents were included. The majority were rheumatoid arthritis patients (42.7%). Patients' knowledge about COVID-19 was correlated with social media use (P = .012). Fear of COVID-19 infection correlated with healthcare facility for follow-up visits (P = .024) and fear of disease deterioration if contracting the infection correlated with patients' levels of knowledge (P = .035). Both types of fear did not correlate with patients' perceptions of disease activity. However, patients' perceptions of worsened disease activity were correlated with unplanned healthcare visits (P < .001), medication non-adherence, and difficulty accessing medication (P = .010 and .006, respectively). CONCLUSION: The COVID-19 pandemic and surrounding public health measures could affect rheumatic patients' health management which might contribute to disease flare-up and subsequently taxing healthcare systems even further.
