Comparison of comorbidities of the Egyptian rheumatoid arthritis patients to the global cohort of the COMORA study: a post-hoc analysis

The Use of Ultrasound for Detecting the Association Between Endothelial Dysfunction and lp13.3 Genomic Region rs646776 Polymorphism in Patients With Rheumatoid Arthritis From the Suez Canal Region

Background  Rheumatoid arthritis (RA) is an autoimmune disease associated with endothelial dysfunction (ED) and vascular morbidity. The study aimed to use ultrasound to assess the relationships of lp13.3 genomic region-rs646776 polymorphism with ED and subclinical cardiovascular disease (CVD) in patients with RA from the Suez Canal region in Egypt. Results This case-control study included 66 patients with RA and 66 healthy controls. Polymerase chain reaction-restriction fragment length polymorphism showed that the genotype frequencies for lp13.3 genomic region-rs646776 polymorphism in the RA group were 62.1% (n = 41), 34.8% (n = 23), and 3% (n = 2) for the AA, AG, and GG genotypes, respectively. The prevalence of the G allele was higher in the RA group than in the control group (20.5% and 7.6%, respectively; p < 0.01). Furthermore, ED was more prevalent in G allele carriers than in A allele carriers, suggesting a greater probability of ED and CVD in patients with RA with the GG genotype than in those with other genotypes. Conclusions This study indicated the validity of ultrasound in detecting the association between lp13.3 genomic region-rs646776 polymorphism and ED in Egyptian patients with RA. These findings could help identify high-risk patients with RA who may benefit from active treatment to help prevent CVD.

Consensus recommendations on managing the selected comorbidities including cardiovascular disease, osteoporosis, and interstitial lung disease in rheumatoid arthritis

BACKGROUND

Rheumatoid arthritis (RA)-related comorbidities, including cardiovascular disease (CVD), osteoporosis (OP), and interstitial lung disease (ILD), are sub-optimally managed. RA-related comorbidities affect disease control and lead to impairment in quality of life. We aimed to develop consensus recommendations for managing RA-related comorbidities.

METHODS

The consensus statements were formulated based on emerging evidence during a face-to-face meeting of Taiwan rheumatology experts and modified through three-round Delphi exercises. The quality of evidence and strength of recommendation of each statement were graded after a literature review, followed by voting for agreement. Through a review of English-language literature, we focused on the existing evidence of management of RA-related comorbidities.

RESULTS

Based on experts' consensus, eleven recommendations were developed. CVD risk should be assessed in patients at RA diagnosis, once every 5 years, and at changes in DMARDs therapy. Considering the detrimental effects of nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids on CVD risks, we recommend using the lowest possible dose of corticosteroids and prescribing NSAIDs cautiously. The OP/fragility fracture risk assessment includes dual-energy X-ray absorptiometry and fracture risk assessment (FRAX) in RA. The FRAX-based approach with intervention threshold is a useful strategy for managing OP. RA-ILD assessment includes risk factors, pulmonary function tests, HRCT imaging and a multidisciplinary decision approach to determine RA-ILD severity. A treat-to-target strategy would limit RA-related comorbidities.

CONCLUSIONS

These consensus statements emphasize that adequate control of disease activity and the risk factors are needed for managing RA-related comorbidities, and may provide useful recommendations for rheumatologists on managing RA-related comorbidities.

Comparative study evaluating antihistamine versus leukotriene receptor antagonist as adjuvant therapy for rheumatoid arthritis

PURPOSE

Investigating the efficacy and safety of rupatadine (RUP) versus montelukast (MON) as adjuvant therapy for patients with rheumatoid arthritis (RA).

METHODS

From December 2018 to December 2019, 75 patients with active RA were enrolled in this randomized double-blind placebo-controlled study. The patients were randomized into three groups (n = 25 in each group); methotrexate (MTX) group which received MTX 15-25 mg/week plus placebo tablet once daily; MTX/RUP group which received MTX plus RUP 10 mg once daily; and MTX/MON group which received MTX plus MON 10 mg once daily. The treatment duration was 3 months. At baseline and 3 months after treatment, blood samples were collected for the biochemical analysis of high-sensitivity C-reactive protein (hs-CRP), interleukins 8 and 17 (IL-8, IL-17), E-selectin, and clusterin (CLU) levels. Clinical and functional assessments using Disease Activity Score-CRP (DAS28-CRP) and Multidimensional Health Assessment Questionnaire (MDHAQ) were performed.

RESULTS

Both RUP and MON produced clinical and functional improvements which were translated by significant improvements in DAS28-CRP score and MDHAQ. Rupatadine significantly reduced all measured parameters (P < 0.05) except for IL-17 and CLU. Montelukast significantly decreased all measured variables (P < 0.05) except for E-selectin. Interleukin-8 was positively correlated with IL-17 and CLU, while hs-CRP was positively correlated with E-selectin and body mass index (BMI). Both drugs were well tolerated; somnolence was the common side effect for RUP. No neuropsychiatric events were reported with MON.

CONCLUSION

Rupatadine or montelukast may serve as a potential adjuvant therapy for patients with rheumatoid arthritis secondary to the preliminary evidence of efficacy and safety. ClinicalTrials.gov identifier NCT03770923, December 10, 2018.

Management and Comorbidities in Middle-European Patients with Rheumatoid Arthritis: A Retrospective, Cross-sectional Comparison with COMORA Data

Objective:

To assess disease-specific characteristics and comorbidities in consecutive Middle-European Rheumatoid Arthritis (RA) patients, and to compare results with international data.

Methods:

Cross-sectional retrospective analysis of consecutive RA patients from a Middle-European outpatient service. Data are compared to those of the international “Co-morbidity in Rheumatoid Arthritis” (COMORA) cohort.

Results:

80 RA patients with mean disease duration of 10.6 ± 8.3 years were enrolled within 5 months. Age was 62 ± 13 years and 75% were female. The Middle-European cohort showed slightly lower disease activity than the Austrian COMORA subcohort. 88.8% of all Middle-European RA patients were in remission or had low disease activity. Despite comparable disease characteristics, the percentage of patients ever treated with biological disease-modifying antirheumatic drugs (bDMARDs) was lower in the middle-European cohort (36.3%) than in the Austrian subcohort of COMORA (59%), but similar to the international COMORA cohort (39%). More smokers were in the Austrian COMORA subcohort (48.0) than in the Middle-European (22.5%) and the COMORA cohort (13%). Hypertension (38.8%) and osteoporosis (30.0%) were the most frequent comorbidities.

Conclusion:

Comparison of RA patients from this Middle-European cohort with the Austrian COMORA subcohort showed less frequent use of bDMARDs during disease course – probably according to the local referral structure. 88.8% of the Middle-European RA-patients achieved the treat-to target-aim of remission or low disease activity.

Epidemiology and treatment patterns of rheumatoid arthritis in a large cohort of Arab patients

OBJECTIVES

There is limited information on the epidemiology and treatment patterns of rheumatoid arthritis (RA) across the Arab region. We aim in this study to describe the demographic characteristics, clinical profile, and treatment patterns of patients of Arab ancestry with RA.

METHODS

This is a cross sectional study of 895 patients with established rheumatoid arthritis enrolled from five sites (Jordan, Lebanon, Qatar, Kingdom of Saudi Arabia (KSA), and United Arab Emirates). Demographic characteristics, clinical profile, and treatment patterns are compared between the five countries.

RESULTS

The majority of our patients are women, have an average disease duration of 10 years, are married and non-smokers, with completed secondary education. We report a high (>80%) ever-use of methotrexate (MTX) and steroids among our RA population, while the ever-use of disease modifying anti-rheumatic drugs (DMARDs) and TNF-inhibitors average around 67% and 33%, respectively. There are variations in RA treatment use between the five country sites. Highest utilization of steroids is identified in Jordan and KSA (p-value < 0.001), while the highest ever-use of TNF-inhibitors is reported in KSA (p-value < 0.001).

CONCLUSION

Disparities in usage of RA treatments among Arab patients are noted across the five countries. National gross domestic product (GDP), as well as some other unique features in each country likely affect these. Developing treatment guidelines specific to this region could contribute in delivering standardized therapies to RA patients.

Rheumatology in Egypt: back to the future

Medical knowledge in ancient Egypt had a remarkable reputation since rulers of other empires used to request the pharaoh to send them their best physician to treat their beloved ones. Many rheumatologic conditions as giant-cell arteritis, reactive arthritis and other forms of spondyloarthritis have been identified in ancient Egyptian materials. Rheumatologists in Egypt are enormously expanding and mastering the tools that aid them in enhancing the management of rheumatic diseases. More Egyptian rheumatologists are actively participating in the annual European League Against Rheumatism (EULAR) and American College of Rheumatology conferences and those attached to well known state of the art centers are increasing. EULAR certified Egyptian MSUS trainers are effectively performing regionally. This review throws light on the rheumatology practice in Egypt, its progress from ancient times passing through Egyptian medical healthcare services, education systems for rheumatologists, rheumatology associations, an overview on the spectrum of rheumatic diseases through publications in the field till future perspectives. Rheumatology in Egypt is an actively growing and dynamic specialty of medicine with considerable contributions to the world's literature. These days, persistent efforts are mandatory to raise the standard of clinical and basic research, to optimize clinical practice with regard to new biologics, to develop tailored and targeted therapies for the rheumatic diseases, and to meet the medical demands of the exponentially increasing Egyptian population. Opportunities and challenges discussed high-lighten future perspectives needed to boost the rheumatology practice in Egypt.

Role of LncRNA-AF085935, IL-10 and IL-17 in Rheumatoid Arthritis Patients With Chronic Hepatitis C

BACKGROUND

The current study aimed at testing the effect of corticosteroid therapy on serum levels of interleukin-10 (IL-10) and IL-17 as well as lncRNA-AF085935 in patients of rheumatoid arthritis (RA) associated with hepatitis C virus (HCV) and evaluating the usefulness of using these parameters to predict the therapeutic efficacy of steroids in these patients.

METHODS

Thirty healthy control subjects and 65 chronic HCV patients with RA were included in our study. Patients were subjected to clinical examination, abdominal ultrasound, and liver biopsy and received 6-methyl-prednisolone (PDN) 16 mg/day for 48 weeks. Blood samples were collected from all subjects and serum was separated to assess IL-10 and IL-17 by ELISA and HCV RNA and lncRNA-AF085935 by qRT-PCR.

RESULTS

Our study revealed that there were significant increases in serum levels of IL-10, IL-17 and lncRNA-AF085935 in RA patients associated with HCV compared with healthy control subjects. Also there were significant increases in serum levels of IL-10 and HCV RNA and a significant decrease in serum level of IL-17 in patients after corticosteroid therapy, while lncRNA-AF085935 is not significantly changed.

CONCLUSION

LncRNA-AF085935 might be a useful candidate biomarker for the early detection of RA associated with HCV, providing potential new strategies for early screening and therapy of these patients. IL-17 is a non-invasive prognostic marker to predict the efficacy of corticosteroid therapy in RA patients associated with chronic hepatitis C.
