    Int J Rheum Dis, 2010;13:121.
    DOI: 10.1111/j.1756-185X.2010.01502.x
    BACKGROUND: In Malaysia, patients have a choice of attending a public (fully subsidised bygovernment) hospital (PUBH) or a private (fee-paying) hospital (PRIH) for their healthcare.The aim of this study was to, firstly, provide an overview of the characteristics of MalaysianSLE patients attending rheumatology clinics, and secondly, to ascertain if there were any dif-ferences between patients attending PUBH and PRIH.
    METHODS:A standardised questionnaire was administered to all SLE patients attendingrheumatology clinics in a PRIH in Selangor state and a PUBH in Negeri Sembilan state dur-ing the months of September to December 2009.
    RESULTS:One hundred and thirty patients were included in the study. There were 55(42.3%) patients from PRIH and 75 (57.7%) from PUBH. 93.8% were female. 61.5% wereChinese, 29.2% Malay and 7.7% Indians. The majority of patients completed secondaryschooling (46.9%) with significantly less PUBH patients going onto higher education(P = 0.001). 53.8% were in fulltime employment with 37.7% housewives/unemployed.There were significantly more unemployed patients in PUBH (45.3%) versus PRIH (27.2%)(P = 0.05). 33.8% of patients were single, 60.8% married and 3.8% divorced. Average ageat SLE diagnosis was 29.8510.17 years. At diagnosis, the most common presenting symp-tom was related to the mucocutaneous system 70.8%, followed by joints 55.3%, haemato-logical 46.9% and renal 23.1%. Significantly more patients had renal involvement atdiagnosis in PUBH (33.3%) versus PRIH (9.1%) (P = 0.001). At the time of survey, therewere 12 (9.2%) patients in remission. Of those still symptomatic, 48.5% related to themucocutaneous system, 32.3% joints, 27.7% haematological, 22.3% renal, with significantlymore current renal disease in PUBH (30.7%) versus PRIH (10.9%) (P = 0.008). The mostfrequently prescribed drug was prednisolone in 83.1% of patients, followed by hydroxychlo-roquine 68.5% and azathioprine 23.1%. Only 64.8% of patients on prednisolone were onbone protective agents. More patients in PRIH were on prednisolone (90.9%) versus PUBH(77.3%) (P = 0.04), but more patients were on activated vitamin D in PUBH (72%) versusPRIH (29.1%) (P < 0.001).
    CONCLUSION:The demographics and clinical characteristics of SLE patients attending PUBHand PRIH are significantly different. This has important implications when considering edu-cational and treatment strategies

    APLAR Journal of Rheumatology, 2006;9 Suppl 1:A89.
    Objective: To determine the epidemiological, clinical and laboratory features of the patients with gout, on follow up in Rheumatology Outpatient Clinic, Hospital Seremban.
    Methods: This was a retrospective study. Case notes of all our existing gout patients were reviewed, and data on demography, clinical features, associated conditions, and laboratory findings were noted.
    Results: 54 patients were studied, 48 (89%) were male and 6 (11%) were female at the ratio of M : F = 8:1, 30 (57%) of them had the onset of symptoms at their 3rd and 4th decades of life. The majority were the Malays 39 (72%), followed by the Indians 11 (20%) and the Chinese 4 (8%). Commonly associated conditions were hypertension in 37 (68.5%), obesity (BMI of 30 and above) in 36 (66.7%) and hyperlipidaemia in 36 (66.7%) of them. Mixed hyperlipidaemia (High TG and LDL cholesterol) were found in 19 (53%). Underlying history of diabetes mellitus 7 (13%), alcohol consumption 8 (15%), smoking habits 22 (40%) and family history of gout 18 (33%). Half of our patients 27 (50%) had at least 2 or more joints involvement. 28 (52%) of them had tophaceous gout. Among those with tophaceous gout, 18 (64%) had renal impairment with serum creatinine of .150mmol/l. 6 (31.5%) of the patients with renal impairment found to have renal calculi on ultrasonography.
    Conclusion: There was male predominance in our group of patients which was consistent with other reported epidemiological studies. Hypertension, mixed hyperlipidaemia and obesity were common associated conditions while diabetes mellitus, smoking and family history of gout were not. The majority of gout patients in our clinic were Malays and due to religious reasons, alcohol was not a common associated factor. Half of our patients had multiple joints involvement and more than half also had tophaceous gout. There was high incidence of renal impairment seen in patients with tophaceous gout. These could be due to delay in seeking medical treatment, present of renal calculi and possibly contributed by associated hypertension and diabetes mellitus.
  5. To compare ESR and CRP as predictors of disease activity in rheumatoid arthritis patients in Hospital Seremban. [Abstract]
    Gun SC, Loh YL, Das Gupta E
    APLAR Journal of Rheumatology, 2006;9 Suppl 1:A185.
    Background: Rheumatoid arthritis (RA) is an inflammatory disease. Predictors of disease activity include presence of joint inflammation, blood investigations such as erythrocyte sedimentation rate (ESR) and c-reactive protein (CRP). ESR is said to be imprecise as it is affected by aging, female sex, obesity, pregnancy, anaemia and polycythaemia. But it is inexpensive and easy to perform. CRP is produced as an acute phase reactant by the liver in response to interleukin 6 and other cytokines. CRP is more specific but costs more than ESR. Both tests are done in the rheumatology clinic of Hospital Seremban. Objective: To compare the usefulness of ESR and CRP as a predictor of disease activity in rheumatoid arthritis (RA) patients. Method: This was a retrospective study. The medical records of 248 RA patients who attended the rheumatology clinic, Hospital Seremban between 1 January 2004 and 31 Dec 2004 were reviewed. The following data were obtained: joint swelling and tenderness, other clinical features which indicate inflammation secondary to infection or trauma and inflammation of soft tissue, ESR, CRP, FBC and UFEME. Results: Data was analysed and the results showed that a total number of 248 patients were seen. There were 13 defaulters. Of the 248 patients there were 929 patients' visits. Of the total number of patients' visits where patients clinically had active disease, 80.2% had raised ESR while 88.8% had raised CRP. As for visits where patients had quiescent disease clinically, 57.3% had normal ESR and 36.5% had normal CRP. Conclusion: CRP is more sensitive but less specific than ESR. This suggests that we still should use both tests as they complement each other. ESR can serve as a countercheck for CRP and vice versa.
  6. A survey on the management of gout in Malaysia
    Yeap SS, Goh EM, Gun SC
    Int J Rheum Dis, 2009 Dec;12(4):329-35.
    PMID: 20374371 DOI: 10.1111/j.1756-185X.2009.01431.x
    AIM: The aim of this study was to ascertain the management of gout by doctors in Malaysia.
    METHODS: A cross-sectional questionnaire survey was carried out among doctors attending rheumatology post-graduate courses, where gout was not a lecture topic.
    RESULTS: A total of 128 questionnaires were analyzed, of which the majority (67: 52.3%) were general practitioners. In the treatment of acute gout, 68.0% use non-selective non-steroidal anti-inflammatory drugs (NSAIDs), 53.9% use selective COX-2 inhibitors (coxibs), 66.4% use colchicine and 10.2% use allopurinol (ALLO). In the treatment of chronic gout, 36.7% use NSAIDs, 44.5% use coxibs, 19.5% use colchicine and 93% use ALLO. In both acute and chronic gout, corticosteroids (CS) are not used by over 90% of respondents. Fifty percent would stop ALLO during an acute attack. 95.3% do not start ALLO during an acute attack; 87.5% would start ALLO after the attack, with a median of 14 days afterwards. Once ALLO was started, 54.7% would continue indefinitely. Regarding target urate levels while on treatment, 10.9% would be satisfied with a high normal range, 21.9% middle of the range, 18.0% low normal range and 45.3% anywhere within the normal range. Fifteen percent would treat asymptomatic hyperuricemia.
    CONCLUSIONS: In Malaysia, anti-inflammatory agents are most commonly used for the treatment of acute and chronic gout, with corticosteroid usage at a low level. However, there are areas of concern regarding the diagnosis of gout and the usage of ALLO which are not consistent with current guidelines

Indications for early referral include: i. Early morning stiffness (EMS) of 30 mins ;- ii. Metatarsophalangeal (MTP) / metacarpophalageal (Mep) involvement. iii. 2 or more swollen joints.
  8. Rheumatology in Malaysia
    Yeap SS, Gun SC, Das Gupta E, Veerapen K
    Rheumatol Int, 2020 Jun;40(6):829-836.
    PMID: 32285145 DOI: 10.1007/s00296-020-04577-6
    Malaysia is a developing country in the South-East Asian region with a significant burden of disability from musculoskeletal disease. Rheumatology in Malaysia is a relatively young speciality. Currently, there is approximately 1 rheumatologist per 390,000 population, mostly concentrated in the urban areas. This article aims to give a brief overview of the research in rheumatology, the healthcare system, and rheumatology training and education in Malaysia. From 1950 until mid-2019, there were 547 publications about rheumatological conditions from Malaysia, with a 27-fold increase in the numbers from the period before 1980 compared to 2010-2019. Although there is universal access to healthcare through the public (government funded) hospitals and clinics, as well as a system of private healthcare, funding for expensive biological therapies remain patchy and scarce, leading to significant under-utilization of such treatments in rheumatology patients. Training in rheumatology in Malaysia is well established with a formalised training curriculum introduced in 2004, followed by the introduction of training in musculoskeletal ultrasound in 2006. To improve care for patients with musculoskeletal conditions, there has been regular continuing educational meetings and courses, not just for rheumatologists, but also for other medical professionals, as not all areas in Malaysia have easy access to rheumatology services. Thus overall, despite the small number of rheumatologists, rheumatology in Malaysia has made encouraging progress over the past 2 decades, but improvements in patient care, training, education and research need to continue in the future.
  9. Fulltext Ethnic differences in the prognostic utility of rheumatoid factor isotypes and anticyclic citrullinated peptides in rheumatoid arthritis patients: a cross-sectional study
    Gomez EL, Gun SC, Somanath SD, Chinna K, Radhakrishnan AK
    Mod Rheumatol, 2013 Jul;23(4):716-21.
    PMID: 22854883 DOI: 10.1007/s10165-012-0718-6
    OBJECTIVES: The prognostic significance of rheumatoid factor (RF) and anticyclic citrullinated peptide antibody (anti-CCP) in rheumatoid arthritis (RA) remains contentious due to the conflicting lines of evidence. This study aims to determine the association between RF isotypes and anti-CCP with disease severity in RA patients from three ethnic groups.
    METHODS: A total of 147 RA patients from three different ethnic groups (Malays, Chinese, and Indians) who fulfilled the 1987 American College of Rheumatology (ACR) revised criteria for RA were recruited into this study. The seroprevalence of RF isotypes immunoglobulin (Ig)A, IgG, and IgM, as well as anti-CCP was determined using commercial enzyme-linked immunosorbent assay (ELISA) kits. Multinomial regression analysis was performed to assess the independent effects of autoantibody status on the development of deforming and erosive RA and the presence of extra-articular manifestations (EAM).
    RESULTS: In Chinese patients, we found a significant association (p < 0.05) between IgG RF and anti-CCP and the presence of erosive disease, as well as IgM RF and IgG RF with the presence of joint deformities. In Indian patients, IgM RF was associated with deforming disease, whereas none of the antibodies were associated with disease severity in Malay patients. Multinomial regression analysis revealed that IgG RF was the most important predictor variable for erosive disease in Chinese patients, and IgM RF the only predictor variable associated with deforming disease in both Chinese and Indian RA patients.
    CONCLUSIONS: There is variability in the phenotypic association of RF isotypes and anti-CCP in relation to disease severity of RA in the three ethnic groups. RF, in particular, IgG and IgM, may be better prognosticators of severe disease in Chinese and Indian patients.
  10. Fulltext Clinical characteristics of gout: a hospital case series

    PMID: 25606228 MyJurnal
    INTRODUCTION: Gout is an increasingly common medical problem. The traditional risk factors of male sex and high red meat or alcohol consumption have been joined with newer risks such as increased life expectancy, and the metabolic syndrome (hypertension, diabetes, dyslipidaemia, truncal obesity).
    METHODS: This was a retrospective study to determine the epidemiology, clinical features, associated conditions as well as renal related conditions in existing gout patients followed-up in Rheumatology outpatient clinic, Hospital Tuanku Ja'afar, Seremban.
    RESULTS: Over a three month period, we identified 54 gouty patients on our follow-up, the majority being male, Malay ethnicity, with the age of onset in the third and fourth decades of life. Commonly associated risk factors were hypertension, hyperlipidaemia and obesity. However, underlying history of diabetes mellitus, alcohol consumption, and family history were not commonly associated with gout in our group of patients. Half of our patients had at least two or more joints involvement. About half of the patients with tophaceous gout had renal impairment.
    CONCLUSION: Our series of gout patients highlight the high prevalence of cardiovascular risk factors. The high prevalence of tophi and renal impairment is a cause for concern.

  11. Fulltext The prevalence of rheumatoid factor isotypes and anti-cyclic citrullinated peptides in Malaysian rheumatoid arthritis patients
    Gomez EL, Gun SC, Somnath SD, D'Souza B, Lim AL, Chinna K, et al.
    Int J Rheum Dis, 2011 Feb;14(1):12-7.
    PMID: 21303477 DOI: 10.1111/j.1756-185X.2010.01573.x
    AIM: The purpose of this study is to compare the prevalence of rheumatoid factor (RF) isotypes and second generation anti-cyclic citrullinated peptides (anti-CCP) in Malaysian rheumatoid arthritis (RA) patients.
    METHODS: In this cross-sectional study, 147 established RA patients from three ethnic groups were recruited from a major rheumatology clinic in Malaysia. Enzyme-linked immunosorbent assays (ELISA) for serum RF isotypes IgA, IgG and IgM as well as second-generation anti-CCP were performed and the prevalence of each auto-antibody was compared in the three ethnic groups.
    RESULTS: The anti-CCP was the most prevalent auto-antibody in each of the ethnic groups, followed closely by RF IgM and RF IgG. Rheumatoid factor IgA was the least prevalent across all three ethnic groups. The anti-CCP-RF IgM combination provided the best test sensitivity. Seroprevalence of anti-CCP was strongly associated with the presence of each of the RF isotypes. The seroprevalence of RF and anti-CCP did not increase or decrease with advancing age, age at onset and disease duration.
    CONCLUSION: When used alone, anti-CCP provides a diagnostic advantage over RF IgM on the basis of test sensitivity. Considering the high cost of the anti-CCP assay, step-wise serum testing with IgM RF followed by anti-CCP may provide a more economically sensible option to optimize test sensitivity for RA.

  12. Comparison of single nucleotide polymorphisms in the human interleukin-10 gene promoter between rheumatoid arthritis patients and normal subjects in Malaysia
    Hee CS, Gun SC, Naidu R, Das Gupta E, Somnath SD, Radhakrishnan AK
    Mod Rheumatol, 2007;17(5):429-35.
    PMID: 17929139 DOI: 10.1007/s10165-007-0612-9
    In this study, three single nucleotide polymorphisms (SNPs) located within the promoter of the human interleukin (IL)-10 gene [rs1800896 (position: -1087G>A), rs1800871 (position: -824C>T) and rs1800872 (position: -597C>A)] were investigated in 84 rheumatoid arthritis (RA) patients and 95 age- and sex-matched healthy subjects using polymerase chain reaction-restriction fragment length polymorphism method. Production of IL-10 by peripheral blood lymphocytes from the RA patients and healthy subjects cultured in the presence of Concanavalin A (Con A) was determined by using enzyme-linked immunosorbent assay. The results show that the distribution of the IL-10 genotypes did not differ significantly between RA patients and healthy subjects (P>0.05). However, a significant difference was observed in allele frequencies of -824CT, -824TT, -597CA, and -597AA between the RA patients and healthy volunteers (P=0.04). The -1087A/-824T/-597A (ATA) haplotype, which comprises all mutant alleles, was associated with lower IL-10 production when compared with the other haplotypes. In contrast, the RA patients who did not display the ATA haplotype produced significantly higher levels of IL-10 when compared with those carrying either one (P=0.012) or two (P=0.005) ATA haplotypes. Our findings suggest that there is an association between SNPs in the promoter of the human IL-10 gene and susceptibility to RA.

    PMID: 26377236 DOI: 10.1177/0961203315606441
    Pseudo-pseudo Meigs' syndrome (PPMS) has been reported to be a rare presentation of patients with systemic lupus erythematosus (SLE). However, such a presentation is not common in other forms of connective tissue disease. We presented a case of gross ascites, pleural effusion, and marked elevation of CA-125 level (PPMS-like features) that led to a diagnosis of MCTD. The patient responded to systemic steroid therapy.
  15. Knowledge of osteoporosis among primary care doctors in Malaysia. [Abstract]
    Das Gupta E, Goh EML, Gun SC, Hussein H, Shahril NS, Yeap SS
    APLAR Journal of Rheumatology, 2006;9 Suppl 1:A53.
    Background: In the ageing population, osteoporosis (OP) is becoming an increasingly common medical condition. Effective interventions are available that should enable clinicians to limit the magnitude of the burden but this will require the proper knowledge of OP and its management. Objective: To explore family physicians' perceptions of OP and to identify their educational needs in this area.
    Method: Self administered questionnaires about OP knowledge and management were distributed to attendees of Rheumatology Workshops for primary care physicians between March and November 2005, in Malaysia.
    Results: A total of 134 primary care physicians participated in this survey comprising 53% private practitioners, 44% government doctors, 2.2% from academic institutions and 0.7% not stated. The majority 73 (54.4%) had practiced for more than 10 years, 29 (21.6%) under 5 years and 32 (23.9%) between 5 and 10 years. 127 (94.4%) of them saw patients with osteoporosis. Those who had qualified for over 10 years were more likely to treat OP (p = 0.012). 82% felt that osteoporosis was under-diagnosed whereas 14.9% thought it was over diagnosed. This was not related to specialty or years qualified. Regarding the reasons for under-diagnosis of osteoporosis, 71% stated that they had no access to DXA screening, 74% had no access to heel ultrasound, 66% felt the disease was asymptomatic, 37% felt that investigations were costly and only 11% perceived the problem as a lack of referral for specialist opinion. Majority of respondents recognized the risk factors for OP such as increasing age (93%), post menopausal state (90%), positive family history (70%) and a previous low trauma fracture (65%). 7% were not sure how to further investigate a case of OP. For all categories of bone density, under 50% would advise changes in life-style measures. For osteopenia, 65.7% recommended calcium, 54.5% activated vitamin D products. For OP, 79.1% would use bisphosphonates, 50% calcium. In established OP, 80.6% would use bisphosphonates, 44% calcium. Usage of HRT and SERMs ranged between 20% and 30% in all categories. 63% were aware of the Malaysian Clinical Practice Guidelines on Osteoporosis. 22% would not refer to a specialist, whereas 50.4% would refer severe cases only. Almost all (98%) requested for further continuing medical education on OP.
    Conclusions: In this study, the majority of primary care physicians had a reasonable working knowledge of the management of OP. However, 71% had no access to DXA. Therefore, awareness needs to be supplemented by adequate facilities to further improve the management of OP in the community.
  16. Diagnostic accuracy of pneumonia in Hospital Tuanku Ja'afar Seremban, a tertiary hospital
    Poh KW, Cheok LH, Liow JH, Mat Soom MA, Azlina S, Nadiah MN, et al.
    Med J Malaysia, 2020 01;75(1):7-11.
    PMID: 32008012
    OBJECTIVES: The primary objective of this study was to describe the accuracy of pneumonia diagnosis, both community-acquired pneumonia (CAP) and hospitalacquired pneumonia (HAP). Secondary objectives were describing the choice of antibiotics used, pathogens isolated, and predictive parameters in diagnosing pneumonia.

    METHODS: This was a prospective cross-sectional study to determine the accuracy of the diagnosis of CAP and HAP admitted to Hospital Tuanku Ja'afar. All patients aged ≥12 years admitted to the general medical ward with the diagnosis of CAP or HAP were included in the study. Chest radiograph interpretation was done by certified radiologists. An accurate diagnosis of pneumonia was defined by clinical signs and symptoms of pneumonia supported by radiographical evidence.

    RESULTS: A total of 159 patients were enrolled into the study from January 2018 to February 2018. Of these only 59(37.1%) cases were accurately diagnosed as pneumonia. Amongst those with pneumonia diagnosis made by the emergency department, medical officers and specialists of medical department; 65.4%, 60% and 47.3% respectively were not pneumonia. Amoxicillin with clavulanate and azithromycin were amongst the most common first choice of antibiotic used (46.5%). In this study, pathogens were isolated either by blood culture or sputum culture in only 20 (12.6%) patients. There was no significant predictive parameter identified in this study, which included white cell counts, Creactive protein (CRP) levels, erythrocyte sedimentation rate (ESR), and Pao2/FiO2 ratio.

    CONCLUSION: About two-thirds of patients diagnosed with pneumonia did not have a compatible radiological finding. Better tools and systems are needed to aid in the diagnosis of pneumonia.

    PMID: 34386157 DOI: 10.51866/rv1206
    Chronic low back pain, defined as back pain lasting for more than three months, can be divided into mechanical or inflammatory back pain (IBP). IBP typically starts in patients below the age of 40, is improved with activity and worsens with rest. IBP is strongly associated with axial spondyloarthritis. Early recognition of IBP among primary care physicians is essential for timely diagnosis and intervention to ensure the best outcomes for patients with axial spondyloarthritis. This paper describes the Malaysian Society of Rheumatology's recently developed Inflammatory Back Pain Referral Algorithm for primary care physicians, which aims to facilitate the early identification and referral of IBP patients to rheumatologists.

    Rheumatoid arthritis (RA) is a chronic inflammatory condition that can be associated with abnormal bone turnover and hence osteoporosis. Osteocalcin (OC) levels are increased in conditions with high bone turnover, including high RA disease activity. Thus, OC levels could possibly be used as a marker to assess bone health and disease activity in RA patients. As there have been no previous studies looking at serum OC levels in Malaysian RA patients, this study was performed to examine possible correlations between OC, bone mineral density (BMD) and disease activity in this population. A cross-sectional study of 75 female RA patients and 29 healthy controls was performed. Serum OC was measured using a Quantikine® ELISA kit. Dualenergy x-ray absorptiometry (DXA) was used to assess BMD. Serum OC levels were not significantly different between RA patients (median 14.44 ng/mL, interquartile range [IQR 12.99]) compared to healthy controls (median 11.04 ng/mL IQR 12.29) (p=0.198). Serum OC increased with age (Spearman’s rho r=0.230, p=0.047). There was no significant correlation between serum OC and body mass index (BMI), menopause status, BMD, DAS28, swollen or tender joint counts. Overall, there were 11 (14.7%) patients with osteoporosis and 27 (36.0%) with osteopenia. Menopause status was significantly associated with BMD at all sites (lumbar spine p=0.002, femoral neck p=0.004, total hip p=0.002). Serum OC were similar in RA patients compared to healthy controls. In RA patients, serum OC did not correlate with RA disease activity or BMD. Menopause status remains an important influence on BMD. Thus, measuring serum OC levels in Malaysian RA patients was not useful in identifying those at risk of low BMD.

    The objective of this study was to compare the tolerability of methotrexate in two different regimes of folic acid (FA) supplementation in rheumatoid arthritis (RA). We performed a multicenter, cross-sectional observational cohort study on 240 RA patients with 120 patients each in 5 mg of FA weekly and 30 mg of FA weekly supplementation. There were no significant differences for side effects (14.2 versus 22.5%, P=0.523) and discontinuation of methotrexate (3.6 versus 13.3%, P=0.085). RA patients given 5 mg of FA weekly supplementation had a lower disease activity score 28 compared to 30 mg of FA weekly supplementation [3.44 (1.10) versus 3.85 (1.40), P=0.014]. FA supplementation of 5 mg per week and 30 mg per week was associated with similar tolerability of methotrexate in RA patients.
