RESUMEN

Lupus remains a disease with a low prioritisation in the national agendas of many countries in Latin America, the Middle East, and Asia-Pacific, where there is a dearth of rheumatologists and limited access to new or even standard lupus treatments. There is thus an important need for education, advocacy, and outreach to prioritise lupus in these regions to ensure that patients receive the care they need. This article reviews some of the specific challenges facing the care and management of people with lupus in these regions and suggests strategies for improving patient outcomes. Specifically, we review and discuss (with a focus on the aforementioned regions) the epidemiology of lupus; economic costs, disease burden, and effects on quality of life; barriers to care related to disease assessment; barriers to effective treatment, including limitations of standard treatments, high glucocorticoid use, inadequate access to new treatments, and low adherence to medications; and strategies to improve lupus management and patient outcomes. We hope that this represents a call to action to come together and act now for the lupus community, policymakers, health authorities, and healthcare professionals to improve lupus management and patient outcomes in Latin America, the Middle East, and Asia-Pacific.

RESUMEN

Dengue is the most prevalent mosquito-borne disease in Southeast Asia, where the incidence of systemic lupus erythematosus (SLE) is approximately 30 to 53 per 100,000. Severe dengue, however, is rarely reported among individuals with SLE. Here, whether sera of patients with SLE cross-neutralize dengue virus (DENV) was investigated. Serum samples were obtained from individuals with SLE who were dengue IgG and IgM serology negative. Neutralization assays were performed against the three major DENV serotypes. Of the dengue serology negative sera of individuals with SLE, 60%, 61% and 52% of the sera at 1/320 dilution showed more than 50% inhibition against dengue type-1 virus (DENV-1), DENV-2 and DENV-3, respectively. The neutralizing capacity of the sera was significantly greater against DENV-1 (P < 0.001) and DENV-3 (P < 0.01) than against DENV-2 (P < 0.05). Neutralization against the DENV correlated with dengue-specific IgG serum titers below the cut-off point for dengue positivity. Depletion of total IgG from the sera of patients with SLE resulted in significant decreases of up to 80% in DENV inhibition, suggesting that IgG plays an important role. However, some of the SLE sera was still able to neutralize DENV, even with IgG titers <0.1 OD absorbance. Our findings suggest that sera of patients with SLE contain IgG, and possibly other type of antibodies, that can cross-neutralize DENV, which may explain the rarity of severe dengue in individuals with SLE. Further studies, are needed to further substantiate this finding and to elucidate the specific neutralizing epitopes recognized by the sera of individuals with SLE.

RESUMEN

AIM: To determine the incidence and direct costs of NSAID-induced upper GI adverse events in Malaysian rheumatology patients. METHODS: A retrospective, multi-centre, cohort study of rheumatology patients on long-term NSAIDs was conducted. Clinical data of patients treated between 2010 and 2013 were collected for a 24-month follow-up period. The costs of managing upper GI adverse events were based on patient level resource use data. RESULTS: Six hundred and thirty-four patients met the inclusion criteria: mean age 53.4 years, 89.9% female, diagnosis of rheumatoid arthritis (RA; 59.3%), osteoarthritis (OA; 10.3%) and both RA and OA (30.3%). Three hundred and seventy-one (58.5%) patients were prescribed non-selective NSAIDs and 263 (41.5%) had cyclo-oxygenase-2 inhibitors. Eighty-four upper GI adverse events occurred, translating into a risk of 13.2% and an incidence rate of 66.2 per 1000 person-years. GI adverse events comprised: dyspepsia n = 78 (12.3%), peptic ulcer disease (PUD) n = 5 (0.79%) and upper GI bleeding (UGIB) n = 1 (0.16%). The total direct healthcare cost of managing adverse events was Malaysian Ringgit (MR) 37 352 (US dollars [USD] 11 419) with a mean cost of MR 446.81 ± 534.56 (USD 136.60 ± 163.42) per patient, consisting mainly of GI pharmacotherapy (33.8%), oesophagoduodenoscopies (23.1%) and outpatient clinic visits (18.2%). Mean cost per patient by GI events were: dyspepsia, MR 408.98 ± 513.29 (USD125.03 ± 156.92); PUD, MR 805.93 ± 578.80 (USD 246.39 ± 176.95); UGIB, MR 1601.94 (USD 489.74, n = 1). CONCLUSION: The economic burden of GI adverse events due to long-term NSAIDs use in Malaysian patients with chronic rheumatic diseases is modest.

RESUMEN

AIM: The main objective of this study is to elucidate the clinical significance of the SLC2A9/GLUT9 rs11722228 polymorphism among male gout patients. METHOD: We consecutively recruited all newly diagnosed male gout patients who were treatment-naive from the rheumatology outpatient clinics of two Malaysian hospitals. Age-matched healthy male adults were employed as controls. All subjects were tested for the SLC2A9/GLUT9 rs11722228 genotypes, serum uric acid (SUA), urine uric acid and creatinine levels. All gout subjects were examined for the presence of tophi and sonographically screened for renal calculi. RESULTS: A total of 73 male gout patients and 73 age-matched healthy male adults were recruited in this study. The genotypic frequencies of SLC2A9/GLUT9 rs1172228 did not differ significantly between the gout cases and the healthy controls. The gout subjects with the CC genotype had significantly higher SUA levels (P = 0.002), family history of gout (P < 0.050) and the occurrence of renal calculi (P = 0.026). The SUA-adjusted odds ratios (OR) of the occurrence of renal calculi in the CC genotype (OR = 1 [reference]) was significantly higher than the CT genotype (OR = 0.338, 95%CI: 0.141-0.813) and the TT genotype (OR = 0.271, 95%CI: 0.086-0.854). CONCLUSIONS: The genotypic distribution of SLC2A9/GLUT9 rs1172228 in male gout patients did not differ significantly from that of healthy male controls. However, the CC genotype in gout had significant associations with higher levels of SUA, renal calculi and a positive family history of gout.

RESUMEN

The aim of the study is to investigate the correlation of serum cartilage oligomeric matrix protein (COMP) levels with articular cartilage damage based on sonographic knee cartilage thickness (KCT) and disease activity in rheumatoid arthritis (RA). A total of 61 RA patients and 27 healthy controls were recruited in this study. Serum samples were obtained from all subjects to determine the serum COMP levels. All subjects had bilateral ultrasound scan of their knees. The KCT was based on the mean of measurements at three sites: the medial condyle, lateral condyle and intercondylar notch. Besides, the RA patients were assessed for their disease activity based on 28-joint-based Disease Activity Score (DAS 28). Serum COMP concentrations were significantly elevated in the RA patients compared to the controls (p = 0.001). The serum COMP levels had an inverse relationship with bilateral KCT in RA subjects and the healthy controls. COMP correlated significantly with disease activity based on DAS 28 (r = 0.299, p = 0.010), disease duration (r = 0.439, p = < 0.05) and mean left KCT (r = - 0.285, p = 0.014) in RA. The correlation between serum COMP and DAS 28 scores was comparable to the traditional markers of inflammation: erythrocyte sedimentation rate (ESR) (r = 0.372, p = 0.003) and C-reactive protein (CRP) (r = 0.305, p = 0.017). The serum COMP is a promising biomarker in RA which reflects disease activity and damage to the articular cartilage.

RESUMEN

OBJECTIVES: This study aims to determine the predictors of poor sleep quality in rheumatoid arthritis (RA). PATIENTS AND METHODS: This was a monocentric, cross sectional, case-control study which was conducted at the Putrajaya Hospital, Malaysia. We recruited 46 patients with RA (3 males; 43 females; mean age 48.15±14.96) and 46 age and sex-matched healthy controls (3 males; 43 females; mean age 47.11±12.22). RA patients were assessed for their disease activity based on disease activity score in 28 joints, disease damage based on radiographic erosions, and functional status based on Health Assessment Questionnaire Disability Index. The Pittsburgh Sleep Quality Index (PSQI) scores were determined by interviewing all the subjects. Subjects with RA were further subdivided based on their PSQI scores as "good sleepers" with PSQI scores of <5 and "poor sleepers" with PSQI scores of ≥5. RESULTS: The percentage of poor sleepers was significantly higher among RA patients (47.83% versus 9.57%). Median scores of 5 out of 7 components of the PSQI were higher among RA patients compared to controls. Among poor sleepers with RA, a significantly higher proportion tested positive for anti-citrullinated cyclic peptide autoantibodies (p=0.037). Besides, poor sleepers had significantly higher median Health Assessment Questionnaire Disability Index (p=0.017) than good sleepers. However, both Health Assessment Questionnaire Disability Index (p=0.968) and anti-citrullinated cyclic peptide (p=0.431) were insignificant when entered in the equation of a logistic regression model. CONCLUSION: The findings of this study demonstrate a link between functional disability, anti-citrullinated cyclic peptide antibodies, and sleep quality in RA.

RESUMEN

Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease and despite the improvement in the survival in the past few decades, the morbidity due to disease damage remains significant. The objectives of this study were to investigate the disease damagepattern and determine the associated factors of damage in the multi-ethnic Malaysian SLE patients. We consecutively 424SLE patients who attended a consistent follow-up at the National University of Malaysia Medical Centre and Putrajaya Hospital were recruited. Disease damage was assessed using the SLICC/ACR (Systemic Lupus International Collaborating Clinics/American College of Rheumatology) Damage Index (SDI) scores. Information on their demographics and disease characteristics were obtained from the clinical record. Univariate analysis was performed and the best model of independent predictors of disease damage was determined by multivariate logistic regression analysis. A total of 182 patients (42.9%) had disease damage (SDI ≥1). A significantly higher number of Indian patients had disease/organ damage and they predominantly developed steroid-induced diabetes mellitus (SDM). Patients with corticosteroid-induced osteoporosis (CIOP) were more likely to be Malayswhile majority of patients who developed malignancy were Chinese (p<0.05). In the univariate and multivariate analyses, disease damage was significantly associated with age, Indian ethnicity, lower mean cumulative C3 level, neuropsychiatry lupus (NPSLE), and antiphospholipid syndrome (APLS). Patients who had ever and early treatment with hydroxychloroquine(HCQ)were less likely to develop disease damage while more patients who had received oral prednisolone ≥1mg/kg daily over 2 weeks had disease damage (p<0.05). In conclusion, there were inter-ethnic differences in the damage pattern and risks among SLE patients.

RESUMEN

Survivin is a biomarker of cancer known for its anti-apoptotic and cell-cycle regulating properties. In the context of non-cancer pathology, high levels of survivin may be measured in blood and synovial fluid of patients with rheumatoid arthritis (RA) and associate with early joint damage and poor therapy response. The aim of the study was to investigate the value of survivin measurements in blood for diagnosis of RA in the frame of the Malaysian epidemiological investigation of rheumatoid arthritis (MyEIRA) study. The study enrolled RA patients from eight rheumatology centres in Peninsular Malaysia. The healthy controls matched by age, gender and ethnicity were recruited on the community basis from the residential area of the patients. Levels of survivin were measured in blood of RA patients (n = 1233) and controls (n = 1566) by an enzyme-linked immuno-sorbent assay (ELISA). The risk for RA was calculated as odds ratio (OR) and 95% confidence intervals in the individuals with high levels of survivin. The risk was calculated in relation to antibodies against cyclic citrullinated peptides (ACPA), detected by ELISA and HLA-DRB1 shared epitope (SE) alleles, identified by the polymerase chain reaction using sequence specific oligonucleotide method. High levels of survivin were detected in 625 of 1233 (50.7%) RA cases and in 85 of 1566 (5.4%) controls, indicating its high specificity for RA. Survivin was association with an increase in RA risk in the patients having neither SE-alleles nor ACPA (OR = 5.40, 95% CI 3.81-7.66). For the patients combining survivin, SE, and ACPA, the estimated risk for RA was 16-folds higher compared to the survivin negative patients with SE and ACPA(OR = 16.21, 95% CI 5.70-46.18). To conclude, detection of survivin in blood provides a simple test to improve diagnostic and to increase predictability for RA.

RESUMEN

BACKGROUND & OBJECTIVES: Colorectal cancer (CRC) is second only to breast cancer as the leading cause of cancer-related deaths in Malaysia. In the Asia-Pacific area, it is the highest emerging gastrointestinal cancer. The aim of this study was to identify single nucleotide polymorphisms (SNPs) and environmental factors associated with CRC risk in Malaysia from a panel of cancer associated SNPs. METHODS: In this case-control study, 160 Malaysian subjects were recruited, including both with CRC and controls. A total of 768 SNPs were genotyped and analyzed to distinguish risk and protective alleles. Genotyping was carried out using Illumina's BeadArray platform. Information on blood group, occupation, medical history, family history of cancer, intake of red meat and vegetables, exposure to radiation, smoking and drinking habits, etc was collected. Odds ratio (OR), 95% confidence interval (CI) were calculated. RESULTS: A panel of 23 SNPs significantly associated with colorectal cancer risk was identified (P<0.01). Of these, 12 SNPs increased the risk of CRC and 11 reduced the risk. Among the environmental risk factors investigated, high intake of red meat (more than 50% daily proportion) was found to be significantly associated with increased risk of CRC (OR=6.52, 95% CI :1.93-2.04, P=0.003). Two SNPs including rs2069521 and rs10046 in genes of cytochrome P450 (CYP) superfamily were found significantly associated with CRC risk. For gene-environment analysis, the A allele of rs2069521 showed a significant association with CRC risk when stratified by red meat intake. INTERPRETATION & CONCLUSIONS: In this preliminary study, a panel of SNPs found to be significantly associated with CRC in Malaysian population, was identified. Also, red meat consumption and lack of physical exercise were risk factors for CRC, while consumption of fruits and vegetables served as protective factor.

RESUMEN

AIM: To assess the potential risk of tuberculosis (TB) in patients treated with anti-tumor necrosis factor-alpha (TNF-α) agents in Asia. METHODS: Absolute risk increase (ARI) of TB was estimated for three widely used anti-TNF-α therapies using published standardized incidence ratios (SIR) from the French Research Axed on Tolerance of bIOtherapies registry and incidence (absolute risk [AR]) of TB in Asia. Assuming an association of increased TB risk with anti-TNF-α therapy and country TB AR (incidence), the ARI of TB by country was calculated by multiplying the SIR of the anti-TNF-α therapy by the country's TB AR. The numbers needed to harm (NNH) for each anti-TNF-α agent and numbers needed to treat (NNT) to reduce one TB event using etanercept therapy instead of adalimumab or infliximab were also calculated for each country. RESULTS: The ARI of TB with anti-TNF-α therapies in Asian countries is substantially higher than Western Europe and North America and the difference between etanercept versus the monoclonal antibodies becomes more evident. The NNH for Asian countries ranged from 8 to 163 for adalimumab, 126 to 2646 for etanercept and 12 to 256 for infliximab. The NNT to reduce one TB event using etanercept instead of adalimumab therapy ranged from 8 to 173, and using etanercept instead of infliximab therapy the NNT ranged from 13 to 283. CONCLUSION: Higher numbers of patients are at risk of developing TB with anti-TNF-α therapy in Asia compared with Western Europe and North America. The relative lower risk of TB with etanercept may be particularly relevant for Asia, an endemic area for TB.

RESUMEN

AIM: To determine the prevalence of sexual dysfunction (FSD) among women with rheumatoid arthritis attending the Rheumatology Clinic in Universiti Kebangsaan Malaysia Medical Centre (UKMMC) and Hospital Putrajaya, Malaysia, and to determine its associations with potential clinical and disease activity factors. METHOD: This was a cross-sectional study involving women with rheumatoid arthritis between the ages of 20 and 60 years. A validated Malay Version Female Sexual Function Index (MVFSFI) was administered to diagnose FSD. Sociodemographic and disease activity profiles were obtained and those who had and did not have FSD were compared. RESULTS: Among 63 respondents, 51 patients were included in the analysis for FSD. The prevalence of FSD in women with rheumatoid arthritis attending UKMMC and Hospital Putrajaya Rheumatology Clinic was 29.4%. Erythrocyte sedimentation rate (ESR) and Disease Activity Score in 28 joints (DAS28-ESR) correlates with MVFSFI score with r=-0.364 (P=0.009) and r=-0.268 (P=0.057), respectively. Sociodemographic factors that correlate with MVFSFI score were: patient's age (r=0.520, P<0.001); duration of marriage (r=-0.355, P=0.001); husband's age (r=-0.460, P=0.001); age of oldest child (r=-0.449, P=0.001); and age of youngest child (r=-0.627, P<0.001). CONCLUSION: We found in this study that the prevalence of FSD in rheumatoid arthritis in our centers was 29.4%. Age and family dynamics appear to be more important predictors compared to disease activity.

RESUMEN

We investigated the association between cigarette smoking and the risk of developing rheumatoid arthritis (RA) in the Malaysian population. A total of 1,056 RA patients and 1,416 matched controls aged 18-70 years within a defined area of Peninsular Malaysia were evaluated in a case-control study between August 2005 and December 2009. A case was defined as a person with early diagnosed RA using the 1987 American College of Rheumatology criteria for RA. Controls were randomly selected matched for sex, age, and residential area. Cases and controls answered a questionnaire on a broad range of issues, including lifestyle factors and smoking habits wherein current and former smoking was classified as ever-smoking. The presence of anti-citrullinated peptide antibodies (ACPA) was determined for cases and controls. We found that ever-smokers had an increased risk of developing ACPA-positive RA [odds ratio (OR) = 4.1, 95% confidence interval (CI) 1.9-9.2] but not ACPA-negative RA (OR = 0.7, 95% CI 0.3-2.0), compared with never-smokers. A significant dose-response relationship between cumulative dose of smoking and risk of ACPA-positive RA was observed (<20 pack-years OR = 3.3, 95% CI 1.1-9.8; at least 20 pack-years OR = 5.2, 95% CI 1.6-17.6). Hence, smoking is associated with an increased risk of ACPA-positive RA in the Malaysian population, in which the genetic context is similar to several other Asian countries.

RESUMEN

Objective: Although osteoarthritis (OA) is widely accepted as a degenerative disease, autoimmune processes are believed to be involved in the pathogenesis. There are limited studies in this area and most of them focused on antibodies against chondrocyte membrane. In an attempt to address the paucity of evidence in this regard, we explored the clinical significance of antinuclear antibody (ANA) in primary osteoarthritis of the knee (OAK). Method: We studied 106 patients with primary osteoarthritis of at least 1 knee and 63 healthy controls from two tertiary centres in Malaysia from September 2005 to May 2012. All subjects were tested for ANA by immunofluorescence testing, and a titer of 1:40 and above was considered positive. Besides, the radiographs of bilateral knees were evaluated for grading, tibiofemoral compartment involvement and total knee replacement (TKR) implants. We compared the clinical characteristics between the ANA positive and ANA negative OAK cases. Results: The incidence of ANA positivity among the cases (39.4 %) was higher than the controls (27 %) but this difference was statistically insignificant (p=0.754). ANA positive cases showed significantly higher incidence of bilateral and Grade IV OAK with higher frequency of TKR. In the multiple regression analysis, bilateral OAK (p< 0.0001; odds ratio 9.00), Grade IV OAK (p<0.001, odds ratio 3.44) and TKR (p=0.009; odds ratio 2.97) remained associated with ANA positivity. Conclusions: ANA test is a potential prognostic tool in primary OAK and its positivity is associated with the clinical outcomes of bilateral, Grade IV OAK and TKR.

RESUMEN

AIMS: The aim of this study was to evaluate the left ventricular (LV) diastolic dysfunction in rheumatoid arthritis (RA) patients without clinically evident cardiovascular manifestations and to estimate whether there is any correlation between RA disease severity and disability and LV diastolic dysfunction. METHODS: The study was a cross-sectional study involving 53 patients (47 female and 6 male) with RA without clinically evident heart disease and 53 healthy subjects (47 female and 6 male) who served as a control group. Both groups were matched for age and sex. Echocardiographic and Doppler studies were conducted in all patients with RA and control subjects. RESULTS: Of 17 cardiac parameters assessed, only two were abnormal. None of the specific cardiac diastolic dysfunction parameters were significantly different in RA patients compared to the control group. There was no significant correlation between diastolic function values in RA patients and value of Disease Activity Score 28 (DAS-28) and value of Health Assessment Questionnaires Disability Index (HAQDI). Atrial (A) wave velocity was greater in RA patients compared to the control group (0.71 [0.58-0.83] vs. 0.61 [0.51-0.71]; P < 0.04). However, interventricular relaxation time (IVRT) ([73.08 ± 9.92 vs. 70.74 ± 9.02], P = 0.207), lower E/A ratio (1.27 [1.02-1.56] vs. 1.42 [1.20-1.68], P = 0.102), diastolic dysfunction parameters according to Redfield Classification (25 [47.2%] vs. 27 [50.9%] P = 0.56), diastolic dysfunction using E/A (P = 0.321) and tissue doppler imaging (E/E') (P = 0.148) were not different. CONCLUSION: Prevalence of diastolic dysfunction in the rheumatoid arthritis group (47.2%) was not different from controls (50.9%). LV diastolic function had no significant correlation with RA disease severity and duration of disease.

RESUMEN

UNLABELLED: We would like to report a case of a 29-year-old male patient who presented with multiple lymphadenopathy and vague symptoms of low grade fever, cough, weight loss, rashes, vomiting, dry eyes and dry mouth. Physical examination revealed submandibular lymphadenopathy, vasculitic rashes over both lower limbs, and parotid gland enlargement. Blood investigations showed mild anemia with leukocytosis, predominantly eosinophilia and high erythrocyte sedimentation rate and C-reactive protein. Computed tomography of the neck, thorax and abdomen showed bilateral submandibular, submental adenopathy, mediastinal and para-aortic lymphadenopathy with generalized reticulonodular densities in both lower lobes. There were hepatomegaly and bilateral enlarged kidneys with renal cyst. Histopathological examination from the cervical lymph node later revealed non-caseating granuloma, consistent of sarcoidosis. Patient responded well to prednisolone 50 mg daily with subsequent reduction in the size of cervical lymphadenopathy and parotid swelling. KEYWORDS: Lymphadenopathy; Granuloma; Sjogren; Sarcoidosis.

RESUMEN

INTRODUCTION: Psoriatic Arthritis (PsA) is an inflammatory arthritis associated with Psoriasis. Its recognition as an inflammatory disease distinct from Rheumatoid Arthritis has put forward for consideration several questions regarding its specific CVS mortality and morbidity (9, 11, 16, 26). Carotid intima media thickness is a useful surrogate and sensitive marker to determine atherosclerosis even in its subclinical stages (6, 14, 22, 27, 32). OBJECTIVE: Prevalence of carotid intima media thickness in patients with Psoriatic arthritis is unknown in Asian population. We aim to identify the presence of subclinical atherosclerosis in patients with psoriatic arthritis and disease activity association and its predictors in a series of patients with PsA attended to the rheumatology clinic, tertiary hospitals. METHODS: A total of 63 patients with PsA who fulfilled the CASPAR criteria were recruited from UKM Medical Centre and Hospital Putrajaya. Common carotid intima media thickness (IMT) was measured in both right and left carotid artery by using high resolution B-mode ultrasound. This was a cross sectional study first done in Malaysia for PsA patients. RESULTS: The positive IMT (IMT > 1.00 mm) among PsA was observed in 10 out of 63 patients (15.9 %) regardless of background cardiovascular risk. The mean +/- SD of IMT was 0.725 +/-0.260 mm for this study. Variables significantly associated with positive IMT (p < 0.05) included age at the time of study (p = 0.005), waist circumference (p = 0.001), Hypertension (p = 0.007), Diabetes (p = 0.002) and Metabolic syndrome (p = 0.001) and not associated with gender, ethnicity, duration of PsA disease, pattern of PsA, disease activity and severity. Above all, only age had positive IMT independent predictor (p = 0.032), with OR 1.116; 95 % CI (1.010-1.234). CONCLUSIONS: There was a significant association between CVS risk and positive Intima Media Thickness in Psoriatic Arthritis patients. Otherwise, there was no association in disease activity, disease severity and DMARDS therapy with positive Intima Media Thickness in Psoriatic Arthritis patients. The study was approved by Research and Ethics Committee of the faculty of medicine, Universiti Kebangsaan Malaysia with project code FF-114-2008 and by Community Research Center (CRC) of National Institutes of Health (NIH) for the case study in Hospital Putrajaya with the project code NMRR-08-970-2125.
