Associated Factors of Tophaceous Gout: A Study Involving 20 Primary Care Clinics in an Urbanized State in Malaysia.

Objectives: Gout is a treatable disease. A complication of untreated or poorly-controlled gout is tophi formation. We conducted this study to investigate the associated factors of tophaceous gout among patients who attended 20 primary care clinics in Selangor, an urbanized state in Malaysia. Methods: We conducted a cross-sectional study from July to October 2019 that included all patients with gout who attended the clinics. Data on clinical demographics and laboratory results were collected. Comparison between tophaceous and non-tophaceous groups was performed using descriptive analysis. Results: A total of 421 patients with gout were involved in this study, 83 (19.7%) patients had visible tophi and were categorized into the tophaceous group, while the other 338 (80.3%) patients were categorized into the non-tophaceous group. The majority of patients were male with a mean age of 57.6±12.8 years. Three factors found to be significantly associated with tophaceous gout were age at symptom onset [tophaceous (45.6±13.3 years) vs. non-tophaceous (49.7±13.9 years), p = 0.026], mean disease duration of gout [tophaceous (105.2±92.6 months) vs. non-tophaceous (77.6±88.6 months), p = 0.013], and baseline serum uric acid level [tophaceous (622.3±129.1 µmol/L) vs. non-tophaceous (582.6±102.3 µmol/L), p = 0.021]. Conclusions: Tophaceous gout is associated with longer disease duration, higher baseline serum uric acid level, and younger age at symptoms onset. Hence, early initiation of urate-lowering therapy with a treat-to-target approach is crucial to prevent tophi formation.

High prevalence of undiagnosed impaired glucose tolerance in patients with rheumatoid arthritis.

Objectives: Although the risk of diabetes mellitus has been recognised in rheumatoid arthritis, undiagnosed dysglycaemia remained under-reported. The study aimed to determine the prevalence and associated factors of dysglycaemia among patients with rheumatoid arthritis, utilising the oral glucose tolerance test. Methods: This cross-sectional study involved patients with rheumatoid arthritis, aged ⩾30 years. Following an oral glucose tolerance test, they were divided into two: dysglycaemia and normoglycaemia. Demographic and laboratory parameters were compared using logistic regression analyses. Results: There were 35.5% (55/155) patients with dysglycaemia (including 25.8% impaired glucose tolerance, 7.1% diabetes mellitus and 1.9% with both impaired fasting glucose and impaired glucose tolerance). Patients with dysglycaemia were heavier (65.5 ± 12.3 versus 60.7 ± 10.6 kg, p = 0.01), had wider waist (89.0 ± 12.5 versus 83.1 ± 9.6 cm, p < 0.01), lower high-density lipoprotein cholesterol (1.4 ± 0.3 versus 1.5 ± 0.4 mmol/L, p = 0.02), higher triglyceride (1.3 (0.9-1.8) versus 0.9 (0.8-1.2) mmol/L, p < 0.01) and intercellular adhesion molecule-1 (361.79 (290.38-481.84) versus 315.92 (251.45-407.93) ng/mL, p = 0.01). History of smoking (odds ratio: 5.70, confidence interval: 1.27-25.7), elevated triglyceride (odds ratio: 2.87, confidence interval: 1.33-6.22) and intercellular adhesion molecule-1 (odds ratio: 1.003, confidence interval: 1.001-1.006) were significantly associated with dysglycaemia. Conclusions: Prevalence of undiagnosed dysglycaemia, particularly impaired glucose tolerance, was high in these patients with rheumatoid arthritis, using a 75-g oral glucose tolerance test, which was not associated with disease activity or corticosteroid use. Those with high triglyceride, history of smoking and elevated intercellular adhesion molecule-1 were the two significant predictors for dysglycaemia in our patients with rheumatoid arthritis. Oral glucose tolerance test could be an important laboratory investigation for dysglycaemia in these high-risk patients.

A Questionnaire-based Survey on Depression and Anxiety among Rheumatology Patients during the COVID-19 Pandemic: Patient's Perspective.

OBJECTIVES: The Coronavirus Disease 2019 (COVID-19) outbreak is a global pandemic and has caught the attention of the rheumatology fraternity, where patients are thought to be at higher risk of infection. We aimed to study the incidence of COVID-19 infection and depression and anxiety symptoms among patients with rheumatic disease (RD) in Hospital Selayang, Malaysia, during the COVID-19 pandemic. METHODS: A cross-sectional study was conducted via phone interview using a structured questionnaire in patients with RD aged > 18 years old scheduled for clinic appointments from 4 to 28 May 2020, which coincided with the second wave of COVID-19 cases in Malaysia. The questionnaire included demographics, COVID-19 screening questions, depression and anxiety symptoms screening using questions derived from the Patient Health Questionnaire-2 (PHQ-2) and Generalized Anxiety Disorder-2 (GAD-2). RESULTS: Among the 361 patients enrolled, the majority were females (83.1%), and over half (54.3%) were ethnic Malays, 41.6% had rheumatoid arthritis, 34.6% had systemic lupus erythematosus, 12.2% had spondyloarthropathy, and only one (0.3%) patient had COVID-19 infection. The mean age of patients was 48.2 years (range: 16-80 years). The frequency of patients with depression and anxiety symptoms was 8.6% and 6.9%, respectively. Married patients reported feeling more anxious (p =0.013), while patients with tertiary education levels reported feeling more depressed (p =0.012). CONCLUSIONS: The incidence of COVID-19 infection is low, probably due to the low rate of testing. Depression and anxiety symptoms reported by patients in our cohort were modest. Our findings suggest that the COVID-19 pandemic has a greater impact on married patients with RD and those with a higher education level.

Clinical and economic implications of upper gastrointestinal adverse events in Asian rheumatological patients on long-term non-steroidal anti-inflammatory drugs.

AIM: To determine the incidence and direct costs of NSAID-induced upper GI adverse events in Malaysian rheumatology patients. METHODS: A retrospective, multi-centre, cohort study of rheumatology patients on long-term NSAIDs was conducted. Clinical data of patients treated between 2010 and 2013 were collected for a 24-month follow-up period. The costs of managing upper GI adverse events were based on patient level resource use data. RESULTS: Six hundred and thirty-four patients met the inclusion criteria: mean age 53.4 years, 89.9% female, diagnosis of rheumatoid arthritis (RA; 59.3%), osteoarthritis (OA; 10.3%) and both RA and OA (30.3%). Three hundred and seventy-one (58.5%) patients were prescribed non-selective NSAIDs and 263 (41.5%) had cyclo-oxygenase-2 inhibitors. Eighty-four upper GI adverse events occurred, translating into a risk of 13.2% and an incidence rate of 66.2 per 1000 person-years. GI adverse events comprised: dyspepsia n = 78 (12.3%), peptic ulcer disease (PUD) n = 5 (0.79%) and upper GI bleeding (UGIB) n = 1 (0.16%). The total direct healthcare cost of managing adverse events was Malaysian Ringgit (MR) 37 352 (US dollars [USD] 11 419) with a mean cost of MR 446.81 ± 534.56 (USD 136.60 ± 163.42) per patient, consisting mainly of GI pharmacotherapy (33.8%), oesophagoduodenoscopies (23.1%) and outpatient clinic visits (18.2%). Mean cost per patient by GI events were: dyspepsia, MR 408.98 ± 513.29 (USD125.03 ± 156.92); PUD, MR 805.93 ± 578.80 (USD 246.39 ± 176.95); UGIB, MR 1601.94 (USD 489.74, n = 1). CONCLUSION: The economic burden of GI adverse events due to long-term NSAIDs use in Malaysian patients with chronic rheumatic diseases is modest.

Relation of Doppler ultrasound synovitis versus clinical synovitis with changes in native complement component levels in rheumatoid arthritis patients treated with biologic disease-modifying anti-rheumatic drugs.

OBJECTIVES: The complement system plays a fundamental role in mediating the activity of rheumatoid arthritis (RA). Biologic therapy can reduce native complement component levels and its activation. We aimed to study the relation of Doppler ultrasound (US) synovitis versus clinical synovitis with changes in native complement component levels in RA patients on biologic therapy. METHODS: This was a cross-sectional study. Ninety-seven consecutive patients with RA on biologic therapy for at least 3 months were recruited. Clinical, laboratory and Doppler US assessments were performed. The Disease Activity Score in 28 joints (DAS28), Simplified Disease Activity Index (SDAI) and a 12-joint US assessment were carried out. Synovitis was semiquantitatively scored in B-mode and power Doppler (PD) mode. RESULTS: A significant decrease in native complement (i.e. C3 and C4) and C-reactive protein (CRP) levels was observed. This was highly significant for C3 decrease (p<0.0005), and C4 decrease (p<0.0005). Synovitis detected by PD US showed significant negative association with C3 change (p<0.008), where patients with higher C3 change were more likely to have PD US inactive status on assessment. CONCLUSIONS: Our results suggested that disease inactive status determined by PD US but not by clinical assessment can be related with decrease in complement in RA patients treated with biologic therapy.
