RESUMO

Background: An association between serum uric acid (UA) and disease activity in rheumatoid arthritis (RA) patients has not been well studied. We describe RA patients with high and normal UA and study its association with RA activity. Methods: Adult RA patients from the Kuwait Registry for Rheumatic Diseases (KRRD) were studied from February 2012 through March 2022. Patients with documented UA levels were included. UA of >357 µmol/L (6mg/dL) was considered high. Statistical comparison and correlation were made using multivariate logistic regression. Results: Overall, 1054 patients with documented UA. A total of 158 patients (15%) had high UA level with a mean of 409± 44.4µmol/L. The mean age for the high UA group and low UA group were 59.3 ± 10.7 years and 54.5 ± 12.4 years, respectively (p<0.001). 49.4% were female in high UA group, and 62.2% were female in low UA group, respectively (p<0.05). Logistic analysis showed an inverse relation between DAS28 and UA, as lower DAS28 score was associated with higher UA level (p=0.032) OR 1.39. There was a direct relation with HAQ, creatinine and UA. A higher HAQ is associated with a higher UA level (p=0.019) OR 0.78. High creatinine level is also associated with high UA level (p<0.001) OR 0.24. The use of antirheumatic drugs was similar among patients with high and normal UA. Conclusion: RA patients with a higher UA had a lower disease activity despite using similar antirheumatic drugs. The reasons behind this association need to be further studied.

RESUMO

The emergency state caused by COVID-19 saw the use of immunomodulators despite the absence of robust research. To date, the results of relatively few randomized controlled trials have been published, and methodological approaches are riddled with bias and heterogeneity. Anti-SARS-CoV-2 antibodies, convalescent plasma and the JAK inhibitor baricitinib have gained Emergency Use Authorizations and tentative recommendations for their use in clinical practice alone or in combination with other therapies. Anti-SARS-CoV-2 antibodies are predominating the management of non-hospitalized patients, while the inpatient setting is seeing the use of convalescent plasma, baricitinib, tofacitinib, tocilizumab, sarilumab, and corticosteroids, as applicable. Available clinical data also suggest the potential clinical benefit of the early administration of blood-derived products (e.g. convalescent plasma, non-SARS-CoV-2-specific immunoglobins) and the blockade of factors implicated in the hyperinflammatory state of severe COVID-19 (Interleukin 1 and 6; Janus Kinase). Immune therapies seem to have a protective effect and using immunomodulators alone or in combination with viral replication inhibitors and other treatment modalities might prevent progression into severe COVID-19 disease, cytokine storm and death. Future trials should address existing gaps and reshape the landscape of COVID-19 management.

RESUMO

The Kuwait Association of Rheumatology members met thrice in April 2020 to quickly address and support local practitioners treating rheumatic disease in Kuwait and the Gulf region during the coronavirus disease 2019 (COVID-19) pandemic. Because patients with rheumatic and musculoskeletal disease (RMD) may need treatment modifications during the COVID-19 pandemic, we voted online for the general guidance needed by local practitioners. In this review, we have addressed patients' vulnerability with rheumatic disease and issues associated with their optimum management. Our recommendations were based on the formulation of national/international guidelines and expert consensus among KAR members in the context of the Kuwaiti healthcare system for patients with RMD. The most recent reports from the World Health Organization, the Center for Disease Control, the National Institutes of Health-National Medical Library, and the COVID-19 educational website of the United Kingdom National Health Service have been incorporated. We discuss the management of RMD in various clinical scenarios: screening protocols in an infusion clinic, medication protocols for stable patients, and care for patients with suspected or confirmed COVID infection and whether they are stable, in a disease flare or newly diagnosed. Further, we outline the conditions for the hospital admission. This guidance is for the specialist and non-specialist readership and should be considered interim as the virus is relatively new, and we rely on the experience and necessity more than evidence collection. The guidance presented should be supplemented with recent scientific evidence wherever applicable.

RESUMO

OBJECTIVE: In 2016, ASAS and EULAR made joint recommendations for the management of patients with spondyloarthritis. Although Global and European perspectives are important, they cannot accurately reflect the situation for all patients in all countries and regions. As such, the group worked to tailor the existing international recommendations to suit the specific demographic needs of local populations in the Gulf region, with a specific focus on Kuwait. METHODS: Recommendations drafted following a PubMed search for relevant literature were reviewed and then underwent Delphi vote to reach consensus on those to be included. Advice for newly approved agents, including targeted synthetic disease-modifying anti-rheumatic drugs, was included based on the group's clinical experience. RESULTS: The resulting 41 recommendations are grouped into five categories covering key definitions and principles for the management and treatment of both axial and peripheral forms of spondyloarthritis. CONCLUSION: Through adaptation of existing guidelines and incorporating the current evidence and clinical experience of the members of the group, these recommendations have been developed to reflect the unique situation in Kuwait with regard to differing patient profiles, local culture and approved therapeutic approaches, and are designed to aid in clinical decision-making.

RESUMO

People with IRD are at increased risk of infection, and in 2011 EULAR made general recommendations for vaccination in these patients. Global and European perspectives are important, but they cannot accurately reflect the individual situations of patients in different countries and regions. Based on our clinical experience and opinions, we have sought to tailor the original EULAR recommendations to include advice for vaccination with new agents approved in the intervening years-including the new class of targeted synthetic disease-modifying antirheumatic drugs. We have also considered the specific demographic needs of patients in local populations in the Gulf region. The resulting 16 recommendations are grouped into four main categories covering general vaccination guidelines and best-practice for all patients with IRD, followed by a set of recommended vaccines against specific pathogens. The last two categories include recommendations for certain patient subgroups with defined risks and for patients who wish to travel.

RESUMO

Data on spondyloarthritis (SpA) from the Middle East are sparse and the management of these diseases in this area of the world faces a number of challenges, including the relevant resources to enable early diagnosis and referral and sufficient funds to aid the most appropriate treatment strategy. The objective was to report on the characteristics, disease burden, and treatment of SpA in the Middle East region and to highlight where management strategies could be improved, with the overall aim of achieving better patient outcomes. This multicenter, observational, cross-sectional study collected demographic, clinical, laboratory, and treatment data on 169 consecutive SpA patients at four centers (Egypt, Kuwait, Qatar, and Saudi Arabia). The data collected presents the average time from symptom onset to diagnosis along with the presence of comorbidities in the region and comparisons between treatment with NSAIDs and biologics. In the absence of regional registries of SpA patients, the data presented here provide a rare snapshot of the characteristics, disease burden, and treatment of these patients, highlighting the management challenges in the region.

RESUMO

Over the last decade, biologic therapeutic proteins have advanced the treatment of diseases such as rheumatoid arthritis (RA). Therapeutic antibodies such as infliximab, adalimumab, rituximab, tocilizumab, golimumab, certolizumab pegol, the receptor construct etanercept, and abatacept, an anticluster of differentiation (CD)80/anti-CD86 fusion protein, are used as treatment for RA and ankylosing spondylitis (AS). Infliximab, adalimumab, golimumab, certolizumab pegol, and etanercept are inhibitors of tumor necrosis factor (TNF), a key regulator of inflammation. Left untreated, progression of rheumatic diseases due to inflammation can lead to irreversible joint damage and serious disability. One limitation for the use of therapeutic antibodies is immunogenicity, the induction of antibodies by the adaptive immune system in response to foreign substances. The development of antidrug antibodies (ADAs) has a varying impact on the clinical efficacy of biologic agents for the treatment of RA and AS, depending on whether the ADAs are neutralizing or non-neutralizing. Studies have indicated that neutralizing ADAs are associated with a reduced efficacy, decreased drug survival, increased instances of dose escalation, and adverse events. Comparison studies of anti-TNF biologics have demonstrated that each drug has a different sustained efficacy profile depending on immunogenicity. The purpose of this review is to provide rheumatologists with information regarding the effect of neutralizing antibodies on the sustainable efficacy of anti-TNF biologic therapies. This information will be of value to practicing rheumatologists in Africa and the Middle East who should take into account the potential for changes in the efficacy and safety of biologic therapies and closely monitor patients under their care.

RESUMO

OBJECTIVES: Rheumatoid arthritis (RA) is a common, complex autoimmune disease known to be associated with inheritance of certain human leukocyte antigen (HLA)-DR alleles in different populations. This study investigated the association of DRB1 alleles in Kuwaiti patients with RA. MATERIALS AND METHODS: DRB1 alleles were analyzed in 47 Kuwaiti patients and 70 ethnically matched controls using a DNA-based sequence specific primer (SSP) method. RESULTS: The frequency of DRB1*04 allele was higher in patients compared to the controls (P < 0.012). The association with of HLA-DRB1*04 allele in our patients with RA was accounted for mainly by the seropositive group of patients (P < 0.05). Moreover, five patients were homozygous for DRB1*4 compared to none in the controls. None of the other DRB1 alleles tested was significantly higher in the patients. All patients homozygous for the DRB1*04 allele were females. There was no statistically significant difference in the frequency of DRB1*04 allele in patients classified according to presence of erosive disease or extra-articular manifestations. CONCLUSION: Our results indicate that in Kuwaiti patients, RA is associated with the presence of DRB1*04 allele. The lack of association with severity or the phenotype of RA is not surprising since this is a hospital-based study where patients tend to have a more severe disease.
