ABSTRACT

Osteoarthritis (OA) contributes to significant medical and socioeconomic burden in many populations. Its prevalence is expected to rise continuously owing to the combined effects of aging and increase in risk factors, including obesity, physical inactivity, and joint injuries. Pain is a hallmark presentation of OA. Topical nonsteroidal anti-inflammatory drugs (NSAIDs) are recommended by many international guidelines as an early treatment option of the management of osteoarthritic pain. However, the use of topical NSAIDs remains low in Malaysia and appears not to be a preferred agent in managing OA pain by prescribers. There is also limited guidance from local medical bodies on the use of topical NSAIDs to manage OA pain. This consensus recommendation is intended to serve as a practical guide for healthcare practitioners on the use of topical NSAIDs in the management of OA pain. Eight statements and recommendations were finalized covering the areas of OA burden, topical NSAIDs formulations, safety and efficacy of topical NSAIDs, and patient education. Robust evidence is available to support the efficacy and safety of topical NSAIDs, with its benefits further strengthened by ease of use and access. Taking these into consideration, we recommend that healthcare practitioners advocate for the early use of topical NSAIDs over oral NSAIDs for mild-to-moderate OA pain, while engaging in a shared decision-making process with patients for optimal clinical outcomes.

ABSTRACT

The programmed cell death 1 (PDCD1) gene encodes for the PD-1 (programmed death 1) molecule, which negatively regulates self-reactive T- and B-cells in the maintenance of peripheral tolerance. A previous report had shown the development of lupus-like phenotypes in PD-1-deficient C57BL/6 mice, was suggestive to the role of PDCD1 in predisposing to systemic lupus erythematosus (SLE). Hence, we aimed to investigate the association between PDCD1 and SLE susceptibility in the Malaysian population. A TaqMan-based real-time PCR was employed to screen for PD1.1, PD1.3, PD1.5 and PD1.6 in both SLE and healthy control groups of 200 samples each. The observed frequency for PD1.5C/C genotype was significantly higher in Indian SLE patients and Malay controls (p < 0.01). On the other hand, the PD1.5C/T genotype might predispose the Malays to SLE, but confer a protective effect among the Indians (p < 0.01). The PD1.1, PD1.3 and PD1.6 were, however, not correlated to genetic predisposition of SLE in our Malaysian population. In conclusion, PD1.5 variant was significantly associated to SLE susceptibility in our Malaysian cohort. Our failure in replicating the association between other investigated PDCD1 variants and risk of getting SLE might due to ethnic and geographic variations in the distribution of these genetic variants.

ABSTRACT

AIM: To evaluate the clinical and antibody profile of systemic sclerosis (SSc) in a Malaysian cohort. METHODS: Consecutive patients with SSc in University Malaya Medical Centre from March to November 2012 were included in this study. In addition to clinical characterization, all subjects underwent autoantibody testing using Euroline immunoblot assay. The association between clinical features and autoantibody profile was evaluated. RESULTS: There were 31, predominantly Chinese (45.2%), subjects. Limited cutaneous disease was the most common subtype (71%). Raynaud's phenomenon was the most commonly observed feature (83.9%). Nine (29%) had esophageal dysmotility symptoms and 23 (74.2%), including all patients with diffuse SSc, had symptoms of gastro-esophageal reflux disease (GERD). Restrictive pattern on pulmonary function test and evidence of lung fibrosis were seen in more than 70% of patients. Echocardiographic evidence of pulmonary arterial hypertension was seen in 58.1%. Telangiectasia, calcinosis, digital ulcers, digital pulp loss or pitting were seen more commonly in the diffuse subtype. The two most prevalent autoantibodies were anti-Scl-70 and anti-Ro-52. The presence of anti-Scl-70 was significantly associated with restrictive lung disease (P = 0.05). Anti-Ro-52 was associated with control subjects with other autoimmune diseases (P = 0.043). The presence of anti-PM-Scl-75 was associated with overlap syndrome (P = 0.032). Patients with anticentromere antibodies were more likely to have vasculitic rash (P = 0.012). CONCLUSION: In Malaysia, SSc most commonly affects the Chinese. Limited cutaneous is more common than diffuse subtype. Features of CREST (calcinosis, Reynaud disease, esophageal dysmotility, sclerodactyly, telangiectasia) are more commonly observed in the diffuse cutaneous subgroup. Anti-Scl-70 and anti-Ro-52 antibodies are promising biomarkers for pulmonary involvement in SSc.

ABSTRACT

AIM: Mycophenolate is an immunosuppressive agent which has been used in systemic lupus erythematosus (SLE) patients who have failed conventional therapy. However, the use of mycophenolate sodium in extra-renal SLE involvement has yet to be established. This study aimed to assess the efficacy of mycophenolate sodium in extra-renal SLE. METHODS: A total of 14 SLE patients without renal involvement were randomized either to receive mycophenolate sodium or other immunosuppressive agents. Patients were assessed monthly from baseline until week 16. Assessment parameters included SLE Disease Activity Index (SLEDAI) score, other organ-specific parameters and immunological parameters, including anti-double stranded DNA and C3. Steroid-sparing effect of mycophenolate sodium was also evaluated. RESULTS: Mycophenolate sodium produced a significant reduction in SLEDAI scores (P < 0.05) after 16 weeks of treatment. Mixed responses were detected in terms of organ-specific clinical changes. A positive trend was observed in improvement of immunological parameters and steroid dose reduction. No major adverse events were reported in this study. CONCLUSION: Mycophenolate sodium is a safe alternative therapy in SLE patients with extra-renal involvement. The reduction in SLEDAI scores and the observation of no major safety concerns suggest that a larger prospective study of mycophenolate sodium in non-renal SLE is warranted.
