    INTRODUCTION: Gout and hyperuricaemia attributed to genetic and lifestyle factors have been associated with several chronic diseases. This study aimed to determine the association and interaction effects between vascular endothelial growth factor receptor-2 (VEGFR-2) gene polymorphisms (rs1870377 and rs2071559) and dietary patterns on blood uric acid in Malay and Indian adults.
    METHODS: Dietary intakes of 153 Malays and 177 Indians were obtained using a food frequency questionnaire for the construction of dietary patterns using factor analysis. Genotyping of rs1870377 and rs2071559 was performed by real-time PCR using TaqMan probes. Anthropometric measurements, body mass index (BMI) and blood pressure and biomarkers, uric acid, glycated haemoglobin A1c (HbA1c), and blood lipids were determined.
    RESULTS: There were significant differences in the mean values for HbA1c (41±-12 vs 45±-8 mmol/mol, p<0.001) and blood lipids levels (p<0.05) between Malays and Indians. Significant correlations were obtained between uric acid with selected blood lipids (p<0.05) and BMI in Malays (r=0.362, p<0.001) and Indians (r=0.212, p<0.01). Four dietary patterns were extracted from dietary intakes of all subjects: ‘Vegetables diet’; ‘Fruits diet’ (FD); ‘Animal protein and rice diet’; and ‘Fast foods and preserved foods diet’. There were no significant associations between dietary patterns (p=0.054-0.609) and VEGFR-2 gene polymorphisms (p=0.348-0.778) with uric acid. In Malay subjects, the interaction of rs2071559 and FD had a borderline effect (p=0.05) on blood uric acid after adjusting for potential confounders.
    CONCLUSION: The associations and gene-diet interactions involving VEGFR-2 gene polymorphisms and FD on uric acid provide new information on gout and hyperuricaemia risks in Malays.

    The aim of the present study was to test the hypothesis that colchicine may alter Aggregatibacter actinomycetemcomitans-induced immune response and abscess formation in mice. BALB/c mice were either sham-immunized or immunized with heat-killed A. actinomycetemcomitans. Spleen cells were stimulated with heat-killed A. actinomycetemcomitans in the presence or absence of colchicine. Specific IgG subclass antibodies, interferon-gamma (IFN-gamma), interleukin-4 (IL-4) and cell proliferation were determined. The animals were sham-immunized (group I) or immunized with heat-killed A. actinomycetemcomitans (groups II-VII). Colchicine was administered intraperitoneally before (group III), on the same day of (group IV), or after (group V) the primary immunization and on the same day of (group VI) or after (group VII) the secondary immunization. All groups were challenged with viable A. actinomycetemcomitans. The levels of serum-specific IgG subclasses and both IFN-gamma and IL-4 before and after bacterial challenge were assessed. The diameter of skin lesions was assessed. The results showed that colchicine augmented splenic-specific IgG1 and IL-4 as well as cell proliferation but suppressed specific IgG2a and IFN-gamma levels. Enhancement of serum-specific IgG1 and IL-4 levels, suppression of specific IgG2a and IFN-gamma levels as well as DTH response, and delayed healing of the lesions were observed in groups IV and VI, but not in the remaining groups of animals. Therefore, these results suggest that colchicine may induce a T helper 2 (Th2)-like immunity specific to A. actinomycetemcomitans in vitro and that colchicine administered on the same day as the immunization may stimulate a non-protective Th2-like immunity in A. actinomycetemcomitans-induced infections in mice.

    This is a case report of an extremely rare condition of atlanto-axial subluxation secondary to gouty arthritis, which mimicked rheumatoid arthritis at presentation. Gouty arthritis involving the spine is a rare condition. We highlight a case of gouty arthritis involving the atlanto-axial joint resulting in joint instability, subluxation, and neurological deficit. A 66-year-old obese woman who had a polyarticular disease for the previous 3 years presented with neck pain and progressive neurology. A 2-stage procedure was performed: posterior decompression and occipitocervical fusion followed by further anterior trans-oral decompression. However, after an initial neurological improvement, she succumbed to aspirational pneumonia and septicaemia. Atlanto-axial subluxation caused by gouty arthritis can present in the same way as rheumatoid arthritis. Therefore, the possibility of this as a differential diagnosis should be kept in mind.

    In West Malaysia RA appears to be less common than in temperate climates, but more common than in tropical Africa; furthermore, the incidence of gout and SLE is comparable. The clinical manifestations of RA are milder than those seen in more temperate climates. Subcutaneous rheumatoid nodules have not been observed. Positive serological tests for RF are significantly higher than in the general Malaysian population, but still lower than those reported for patients with RA in temperate climates. Of the three main ethnic groups, the highest incidence of positive results is found in the Chinese.

    The methanol extract from the leaves of Phyllanthus niruri L. showed oral antihyperuricemic activity in potassium oxonate- and uric acid-induced hyperuricemic rats. Fractionation of the extract by resin chromatography led to the isolation of a less polar fraction which exhibited the highest reduction of plasma uric acid. Further antihyperuricemic-guided purification of the fraction afforded three lignans, phyllanthin (1), hypophyllanthin (2) and phyltetralin (3), of which 1 significantly reversed the plasma uric acid level of hyperuricemic animals to its normal level in a dose-dependent manner, comparable to that of allopurinol, benzbromarone and probenecid which are used clinically for the treatment of hyperuricemia and gout. Thus, the lignans of P. niruri are potential antihyperuricemic agents worthy of further investigation.

    INTRODUCTION: Cardiovascular disease is a major cause of morbidity and mortality. Primary care doctors as general practitioners (GPs) play a central role in prevention, as they are in contact with a large number of patients in the community through provision of first contact, comprehensive and continuing care. This study aims to assess the adequacy of cardiovascular disease preventive care in general practice through a medical audit.
    METHODS: Nine GPs in Malaysia did a retrospective audit on the records of patients, aged 45 years and above, who attended the clinics in June 2005. The adequacy of cardiovascular disease preventive care was assessed using agreed criteria and standards.
    RESULTS: Standards achieved included blood pressure recording (92.4 percent), blood sugar screening (72.7 percent) and attaining the latest blood pressure of equal or less than 140/90 mmHg in hypertensive patients (71.3 percent). Achieved standards ranged from 11.1 percent to 66.7 percent in the maintenance of hypertension and diabetic registries, recording of smoking status, height and weight, screening of lipid profile and attaining target blood sugar levels in diabetics.
    CONCLUSIONS: In the nine general practice clinics audited, targets were achieved in three out of ten indicators of cardiovascular preventive care. There were vast differences among individual clinics.

    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.

    Background: Gouty arthritis is a disease of global burden in which defective metabolism of uric acid causes arthritis. Gouty arthritis or medications used for its treatment may lead to uric acid-associated complications such as upper gastrointestinal bleeding (UGIB) and renal impairment.

    Methods: In this cross-sectional study with retrospective record review, 403 established gouty arthritis patients were recruited to determine the incidence of UGIB and associated factors among gout patients who were on regular nonsteroidal anti-inflammatory drugs (NSAIDs).

    Results: The mean age of the 403 gouty arthritis patients was 55.7 years old and the majority (n = 359/403; 89.1%) were male. The incidence of UGIB among gouty arthritis patients who were on NSAIDs was 7.2% (n = 29/403). Older age (p < 0.001), diclofenac medication (p = 0.003), pantoprazole medication (p = 0.003), end-stage renal failure (ESRF) (p = 0.007), smoking (p = 0.035), hypertension (p = 0.042) and creatinine (p = 0.045) were significant risk factors for UGIB among the gouty arthritis patients in univariable analysis. Older age (p = 0.001) and diclofenac medication (p < 0.001) remained significant risk factors for UGIB among the gouty arthritis patients in multivariable analysis.

    Conclusions: Age and diclofenac were significantly associated with UGIB among patients with gouty arthritis on regular NSAIDs, indicating that these factors increased the risks of developing UGIB in gout patients. Hence, these high-risk groups of gouty arthritis patients should be routinely monitored to avoid the potential onset of UGIB. Our data also suggest that diclofenac should be prescribed for the shortest duration possible to minimize the risk of developing UGIB in gout patients.

    INTRODUCTION: Gout is one of the most common inflammatory arthritis in Malaysia. It is due to persistent hyperuricemia that leads to the formation and deposition of intra- and periarticular monosodium urate crystals either due to excessive production or insufficient excretion of uric acid. Incidence and prevalence of gout is increasing worldwide, with a higher rate among men compared to women. Malay is the largest ethnic group in Malaysia, followed by Chinese and Indian. SLC2A9 is a renal urate transporter that controls renal uric acid excretion and genetic variants in SLC2A9 are associated with the risk of gout in several populations. This study aimed to test if the SLC2A9 variant (R265H, rs3733591) is also associated with gout among Malays in Malaysia.

    METHODOLOGY: A total of 89 patients with gouty arthritis and 100 normal subjects who consented and were recruited in this study. The serum urate and creatinine were measured. The SNP genotyping was performed using PCR-RFLP method for rs3733591 and BST 1236 was used as a restriction enzyme to cut the targeted amplicons.

    RESULT: SLC2A9 variant was associated with gout, p-value of 0.007, OR=4.713 [95%CI 1.530-14.513], however this association was not significant after adjustment for age and gender with p=0.465 (OR=1.950; 95%CI[0.325-11.718]).

    CONCLUSION: Our data suggest that the genetic variant of SLC2A9 may contribute to the susceptibility of gout among Malays in Malaysia.

    Introduction: Gout is a clinical syndrome resulting from the deposition of monosodium urate monohydrate crystals. Recent studies have shown gout to be a significant metabolic disorder. However, there has been insufficient information on the clinical spectrum in the Malaysian population.
    Objective: This study is conducted to review the clinical characteristics of patients with gout.
    Study methods: In this cross-sectional study 52 patients with gout were recruited. The records of 13 patients from National University of Malaysia Hospital and 39 patients from Putrajaya Hospital, attending the rheumatology clinic between October and December 2005 were reviewed. Results: Gout was found predominantly among ethnic Malays 83%, and Chinese 17% in these centers. The male to female ratio was 12 :1. The peak age of onset of the disease was less than 40 years in 46% of the subjects. Primary gout in females was seen after menopause. 37% cases had a definitive hereditary incidence. At the first presentation 83% had acute monoarthritis and 17% acute polyarticular arthritis. Podagra was seen in 62%. Peripheral joints involvement was seen in 81% patients. Tophaceous gout was seen in 42%. In 85% cases the disease had a chronic polyarticular course, whereas in 15% the disease remained only at a single joint. In 10% cases, there was associated sero-negative arthritis. Associated disorders included hypertension (65%), diabetes mellitus (33%), dyslipidemia (56%), ischemic heart disease (23%), urate nephropathy (39%), uric acid nephrolithiasis (2%). In 88% of cases, there was associated hyperuricaemia. Most of the patients were overweight with body mass index 25-29 (39%) and obese with body mass index 30-70 (36%). Conclusions: Gout is not an unusual disorder in our centre. The age of onset of gout occurred much earlier with forty-six per cent of patients having their first attack of gout before the age of 40. Primary gout in females was seen after menopause. Majority of patients first presented with acute monoarthritis, of which sixty-two per cent presented with podagra. The incidence of tophi was high. Patients with gout should be screened for other associated disorders like diabetes mellitus, hypertension, dyslipidemia and obesity.

    Treat-to-target (T2T) for gout has been established recently to improve its management, which has been reported to be sub-optimal with significant gaps between the goals of treatment and day-to-day clinical practice. T2T recommended a goal of serum urate (SUA) target of <360 μmoI/L in all patients with gout and <300 μmoI/L in patients with tophaceous or severe gout. T2T strategy was applied in the management of gout patients in two Rheumatology clinics from 1 January 2016 onwards. We performed a clinical audit to assess T2T of SUA in gout patients and to identify causes for failure to achieve target SUA among them. There were a total of 304 patients for our analysis. They were of multi-ethnic origin with male predominance (88.8%). They had a mean age of 57.7+13.7 years and mean disease duration of 10.1+8.7 years. The most common comorbidities were hypertension (76.2%), dyslipidemia (52.5%) and diabetes mellitus (DM) (27.4%). Our patients' body mass indexes showed that 47.7% were obese while 34.2% were overweight. Up to 62.4% of our patients had tophi and 42.6% had joint deformities. Only 34.9% of patients achieved target SUA. Nonadherence (52.3%) was the main reason identified for failure to achieve target SUA. The independent predictors for failure to achieve target SUA were nonadherence (HR=7.84, p=0.000) and presence of tophi (HR=1.95, p=0.001).

    Ylang-ylang (Cananga odorata Hook. F. & Thomson) is one of the plants that are exploited at a large scale for its essential oil which is an important raw material for the fragrance industry. The essential oils extracted via steam distillation from the plant have been used mainly in cosmetic industry but also in food industry. Traditionally, C. odorata is used to treat malaria, stomach ailments, asthma, gout, and rheumatism. The essential oils or ylang-ylang oil is used in aromatherapy and is believed to be effective in treating depression, high blood pressure, and anxiety. Many phytochemical studies have identified the constituents present in the essential oils of C. odorata. A wide range of chemical compounds including monoterpene, sesquiterpenes, and phenylpropanoids have been isolated from this plant. Recent studies have shown a wide variety of bioactivities exhibited by the essential oils and the extracts of C. odorata including antimicrobial, antibiofilm, anti-inflammatory, antivector, insect-repellent, antidiabetic, antifertility and antimelanogenesis activities. Thus, the present review summarizes the information concerning the traditional uses, phytochemistry, and biological activities of C. odorata. This review is aimed at demonstrating that C. odorata not only is an important raw material for perfume industry but also considered as a prospective useful plant to agriculture and medicine.

    BACKGROUND: The prevalence, clinical patterns, and causative drugs of cutaneous adverse drug reactions (cADR) vary among the different populations previously studied.
    AIM: To determine the prevalence, the clinical patterns of drug eruptions, and the common drugs implicated, particularly in severe cADR such as Stevens-Johnson Syndrome/Toxic epidermal necrolysis (SJS/TEN) and drug rash with eosinophilia and systemic symptoms (DRESS) in our population.
    METHODS: We analyzed the database established for all cADR seen by the department of Dermatology from January 2001 till December 2010.
    RESULTS: A total of 362 cADR were seen among 42 170 new clinic attendees, yielding an incidence rate of 0.86%. The most common reaction pattern seen was maculopapular eruption (153 cases) followed by SJS/TEN (110 cases) and DRESS (34 cases). Antibiotics was the most commonly implicated drug group (146 cases) followed by anticonvulsants (81 cases) and antigout drugs (50 cases). The most frequently implicated drug was allopurinol (50 cases). Carbamazepine, allopurinol, and cotrimoxazole were the three main causative drugs of SJS/TEN accounting for 21.8%, 20.9%, and 12.7%, respectively, of the 110 cases seen, whereas DRESS was mainly caused by allopurinol (15 cases). Mortality rates for TEN, SJS, and DRESS were 28.6%, 2.2%, and 5.9%, respectively.
    CONCLUSIONS: The low rate of cADR with a high proportion of severe reactions observed in this study was probably due to referral bias. Otherwise, the reaction patterns and drugs causing cADR in our population were similar to those seen in other countries. Carbamazepine, allopurinol, and cotrimoxazole were the three main causative drugs of SJS/TEN in our population.

    BACKGROUND: To date, no studies have been published at evaluating the level of knowledge, awareness and practice of dietary, particularly regarding to urolithiasis in patients or the general population. This study aims to provide basic information on the level of knowledge, awareness and dietary practice among general population in Kuantan, Pahang.

    DESIGN AND METHODS: The respondents (n=30) were conveniently recruited within 10 kilometres radius of Kuantan city. The data were obtained using semi-guided administered questionnaires, which consists of four parts: socio-demographic data, lifestyle and clinical history (Part A); attitude and awareness on dietary practice regarding urolithiasis (Part B); food frequency questionnaire on urolithiasis (Part C) and level of knowledge on urolithiasis (Part D).

    RESULTS: Majority of the respondents were women (70%), Malay (83.3%), mean age of 33.97 (±9.27), married (63.3%), completed higher education level (60%), working with government sector (33.3%) and have fixed monthly income (53.3%). Some of them had hypertension (n=4), diabetes (n=1), gout (n=1) and intestinal problem (n=1). Majority (80%) claimed having no family history of urolithiasis, consumed alcohol (10%), exercise with average frequency 2-3 times/week (46.7%) and heard about urolithiasis from healthcare worker (46.7%). The respondents' awareness about urolithiasis is considered to be good [81.23 (±9.98)] but having poor knowledge score [2.70 (±1.149)]. Majority preferred wholemeal bread, white rice, chicken meat, mackerel fish, chicken egg, apple, carrot, mustard leave and fresh milk in daily intake. Lesser plain water intake than standard requirement was noticed among respondents. Seasoning powder was commonly used for seasoning.

    CONCLUSIONS: Generally, the general population of Kuantan, Pahang was aware of urolithiasis disease but needed more information on dietary aspect in terms of knowledge and food choice.

    OBJECTIVE: Studies found a strong association between allopurinol-induced Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) and the HLA-B*58:01 allele. HLA-B*58:01 screening-guided therapy may mitigate the risk of allopurinol-induced SJS/TEN. This study aimed to evaluate the cost-effectiveness of HLA-B*58:01 screening before allopurinol therapy initiation compared with the current practice of no screening for Malaysian patients with chronic gout in whom a hypouricemic agent is indicated.

    METHODS: This cost-effectiveness analysis adopted a societal perspective with a lifetime horizon. A decision tree model coupled with Markov models were developed to estimate the costs and outcomes, represented by quality-adjusted life years (QALYs) gained, of three treatment strategies: (a) current practice (allopurinol initiation without HLA-B*58:01 screening); (b) HLA-B*58:01 screening before allopurinol initiation; and (c) alternative treatment (probenecid) without HLA-B*58:01 screening. The model was populated with data from literature review, meta-analysis, and published government documents. Cost values were adjusted for the year 2016, with costs and health outcomes discounted at 3% per annum. A series of sensitivity analysis including probabilistic sensitivity analysis were carried out to determine the robustness of the findings.

    RESULTS: Both HLA-B*58:01 screening and probenecid prescribing were dominated by current practice. Compared with current practice, HLA-B*58:01 screening resulted in 0.252 QALYs loss per patient at an additional cost of USD 322, whereas probenecid prescribing resulted in 1.928 QALYs loss per patient at an additional cost of USD 2203. One SJS/TEN case would be avoided for every 556 patients screened. At the cost-effectiveness threshold of USD 8695 per QALY, the probability of current practice being the best choice is 99.9%, in contrast with 0.1 and 0% in HLA-B*58:01 screening and probenecid prescribing, respectively. This is because of the low incidence of allopurinol-induced SJS/TEN in Malaysia and the lower efficacy of probenecid compared with allopurinol in gout control.

    CONCLUSION: This analysis showed that HLA-B*58:01 genetic testing before allopurinol initiation is unlikely to be a cost-effective intervention in Malaysia.
