Burden and management of gout in a multi-ethnic Asian cohort.

Gout has significant impact on the quality of life with over-utilisation of health resources. While lowering serum urate (SU) to ≤ 360 µmol/L improves clinical outcomes, this is usually not achieved. We describe the burden of gout and determine predictors of achieving SU target in gout patients in Singapore. This was a cross-sectional study of 282 gout patients from a Singapore hospital rheumatology service. Sociodemographic and lifestyle factors, co-existing medical conditions and medications, gout history and severity, SU levels and treatment were obtained. Patients with SU ≤ 360 µmol/L were compared with those > 360 µmol/L to determine factors associated with achieving SU target. Descriptive statistics and multivariate model were used. Severe disease was reported in 50%, with emergency attendances and hospitalisations in 33% and 19% respectively, and unemployment in 32%. Only 22% were at SU target and 67% on urate-lowering therapy (ULT) at recruitment. Hypertension, dyslipidaemia, chronic kidney disease and diabetes were prevalent in 56.7%, 48.2%, 32.3% and 18.8%, respectively. Malays had more comorbidities compared to Chinese participants. In multivariate analysis, ULT prescription and ≥ 2 comorbidities were associated with reaching SU target with odds ratios of 3.92 [95% confidence interval (CI) (1.75-8.71)] and 2.65 [95% CI (1.59-4.43)] respectively, independent of age, tophi, disease duration, body mass index, alcohol and diuretic use. Patients with gout have high disease burden resulting in significant healthcare utilisation. SU control is sub-optimal hence the use of ULT remains key in achieving SU target. Patients with other comorbidities are more likely to reach target than those with only gout as a single diagnosis.

Singapore chapter of rheumatologists' updated consensus statement on the eligibility for government subsidization of biologic and targeted therapy for the treatment of psoriatic arthritis.

AIM: There have been major advances in biologic treatment options for psoriatic arthritis (PsA) since the publication of the 2015 consensus recommendations by the Chapter of Rheumatologists, College of Physicians, Academy of Medicine, Singapore, for government-assisted funding, thus warranting a revision of this guideline. METHODS: Recent trials and nine published guidelines on the use of biologic therapy for PsA were reviewed. Based on the synthesized evidence, a task force panel (TFP), consisting of 10 practicing rheumatologists in Singapore, rated the statements pertaining to the use of biologic therapy, using a modified Delphi approach. Consensus was obtained if >70% agreed on a statement. RESULTS: The TFP agreed on 10 recommendations pertaining to the initiation, choice and continuation of biologic therapy. A biologic is indicated in patients with PsA: (a) with at least three swollen and tender joints, digits or entheses; and (b) who have failed at least two conventional synthetic disease-modifying anti-rheumatic drug (csDMARD) strategies for a minimum of 3 months each. Any approved drug class including tumor necrosis factor inhibitors, interleukin-17 inhibitors (IL-17i), IL-12/23i or targeted synthetic DMARDs may be considered as first-line treatment, and continued only if a response is achieved by 6 months. CONCLUSION: These recommendations developed through a formal consensus method may be useful to guide funding considerations for appropriate and equitable use of biologic therapy for eligible patients with PsA.
