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.

Projecting direct medical costs and productivity benefits of improving access to advanced therapy for rheumatoid arthritis: a projection modelling study.

INTRODUCTION: To ensure the sustainability of the AT access improvement, it is important that health system stakeholders have timely, analyzed information accessible for reference and decision-making support. In this study, we projected the direct costs required as well as the expected direct medical cost-offset and productivity benefits resulting from improving the disease control. METHODS: We implemented a deterministic, prevalence-based mathematical model to project the annual cost of rheumatoid arthritis (RA) management within the public healthcare system in Malaysia. We also calculated the annual productivity loss due to uncontrolled RA in monetary value. Using the projection model, we compared the projected costs of the status quo scenario vs. several scenarios of improved advanced therapy (AT) access over a 5-year period. RESULTS: We projected that between 10,765 and 11,024 RA patients in Malaysia over the period of 2020-2024 will need access to AT due to treatment failure with conventional synthetic disease modifying antirheumatic drugs (DMARDs). The projected net total medical cost under the status quo scenario were 163.5 million annually on average (approximately MYR 15,000 per patient per year). Cost related to health service utilization represented the heaviest component, amounting to 71.8% followed by drug cost (24.7%). Under the access improvement scenarios, drug cost constituted a higher proportion of the total medical, ranging from 25.6% to 30.4%. In contrast, the cost of health service utilization shown a reverse pattern (reducing to between 66.3% and 70.1%). Productivity costs were also expected to reduce as AT access improved leading to better outcomes. Treatment shifts to targeted synthetic DMARDs in anticipation of price adjustment appeared to have a cost saving advantage to the health system if all other parameters remain unchanged. DISCUSSION: Improving AT access for RA patients towards the aspirational target appeared to be feasible given the current health budget in Malaysia. Broader socio-economic consequences of productivity and income loss should be included as an important part of the policy consideration. The financial implication of different AT utilization mixes and the anticipated price adjustment will likely result in some cost saving to the health system.

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.

Asymptomatic Lymphocytic Interstitial Pneumonia with Extensive HRCT Changes Preceding Sjogren's Syndrome.

Lymphocytic interstitial pneumonia (LIP) is a rare condition, commonly associated with Sjogren's syndrome (SS). We report a 53-year-old woman with an incidental finding of an abnormal chest radiograph. LIP was diagnosed based on high-resolution computed tomography and lung biopsy, but treatment was not initiated. Six years later, she developed cough and dyspnoea, associated with dry eyes, dry mouth, and arthralgia. While being investigated for the respiratory symptoms, she developed cutaneous vasculitis and was treated with 1 mg/kg prednisolone, which resulted in the improvement of her respiratory symptoms. Physical examination revealed fine bibasal crepitations, active vasculitic skin lesions, and a positive Schirmer's test. Investigations revealed a restrictive pattern in the pulmonary function test, stable LIP pattern in HRCT, and positive anti-Ro antibodies. She was treated with prednisolone and azathioprine for 18 months, and within this time, she was hospitalised for flare of LIP, as well as respiratory tract infection on three occasions. During the third flare, when she also developed cutaneous vasculitis, she agreed for prednisolone but refused other second-line agents. To date, she remained well with the maintenance of prednisolone 2.5 mg monotherapy for more than one year. The lessons from this case are (i) patients with LIP can be asymptomatic, (ii) LIP can precede symptoms of SS, and (iii) treatment decision for asymptomatic patients with abnormal imaging or patients with mild severity should be weighed between the risk of immunosuppression and risk of active disease.

Real-world clinical experience of biological disease modifying anti-rheumatic drugs in Malaysia rheumatoid arthritis patients.

The effect of biologic disease modifying anti-rheumatic drugs (bDMARDs) in treating rheumatoid arthritis (RA) in real-world clinical practice remains unknown in Southeast Asia. We aimed to assess the efficacy and safety of bDMARDs among Malaysian RA patients treated in routine clinical practice. A retrospective medical chart review of RA patients from 11 government hospitals were conducted from January 2003 to January 2014. A standardized questionnaire was used to abstract patient's demographic, clinical and treatment data. Level of disease activity was measured by DAS28 collected at baseline, 3, 6 and 12 months. Three hundred and one patients were available for analysis, mean age 41 (SD, 10.8) years, mean RA duration 12.3 (SD, 6.9) years and 98% had history of two or more conventional-synthetic DMARDs. There were 467 bDMARD courses prescribed with mean bDMARDs duration use of 12.9 months (SD 14.7). Tumour necrosis factor alpha inhibitors were the most common prescribed bDMARDs (77.1%), followed by Tocilizumab (14.6%) and Rituximab (8.4%). We observed significant improvement in mean DAS28 values from baseline to 3, 6 and 12 months (p < 0.001). Overall, 16.9% achieved DAS28 remission at 6 months. A third (35.6%) of patients reported adverse events, three commonest being infections (46.5%), allergy (22.9%) and laboratory abnormalities (12.9%). 3.7% of our patients had tuberculosis. Biologic DMARDs were effective in treating RA in real-world practice in Malaysia, despite a lower remission rate compared to developed countries. Except for higher rates of tuberculosis, the AEs were similar to the published reports.
