Patients and methods: Serum samples were obtained from 48 patients with RA (9 males, 39 females; mean age 60.5 years; range 54 to 64 years) and 48 healthy controls (9 males, 39 females; mean age 57.5 years; range, 47 to 65 years). The enzyme-linked immunosorbent assay method was used for quantitative analysis of serum Pyd. Besides, all RA patients were assessed for joint damage based on modified Sharp score, disease activity based on disease activity score in 28 joints and functional capacity based on health assessment questionnaire-disability index.

Results: The median serum Pyd levels were significantly higher among the RA patients (110.20 ng/mL [92.30-120.64]) compared to the controls (98.22 ng/mL [85.54-111.41]); p<0.05. RA patients with erosive disease had significantly higher serum Pyd levels (p=0.024). There was a significant positive correlation between serum Pyd levels and joint erosion score (r=0.285, p=0.049). The serum Pyd levels had no demonstrable association with disease activity or functional capacity. Steroid therapy did not appear to influence the levels of serum Pyd.

METHOD: This was a cross-sectional study involving SLE patients aged 18-56 years from Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Employment history was obtained from clinical interviews. WD was defined as unemployment, interruption of employment or premature cessation of employment due to SLE at any time after the diagnosis. SLE disease characteristics, presence of organ damage and Safety of Estrogens in Lupus Erythematosus National Assessment-SLE Disease Activity Index (SLEDAI) flare index were determined from the medical records. Self-reported quality of life (QoL) was performed using the Medical Outcomes Study Short Form-36 (SF-36). Demographic factors, disease characteristics, and QoL were compared between patients with and without WD using statistical analyses.

RESULTS: A total of 215 patients were recruited and the majority were Malay (60.5%), followed by Chinese (33.5%), Indian (4.5%) and others (n = 4, 1.9%). The prevalence of WD was 43.2% (n = 93) with 22.3% (n = 48) patients were unemployed at the time of study. Over half the patients with WD (n = 51, 54.8%) had onset of disability at <5 years from diagnosis. Patients with WD had significantly lower health-related QoL. The independent factors associated with WD were SLEDAI score at diagnosis, frequency of flare, Systemic Lupus International Collaborating Clinics score, being married, had lower education and lupus nephritis.

OBJECTIVE: To determine the prevalence and factors associated with APOs in the multi-ethnic SLE populations in Malaysia.Methodology: This was a retrospective review of the consecutive SLE patients who attended the outpatient clinic in two major rheumatology centres from January 2016 until December 2019 with complete pre-pregnancy, antenatal and intra-partum records. APOs include pregnancy loss, prematurity, pre-eclampsia, intra-uterine growth restriction (IUGR) and maternal death. Univariate and multivariable logistic regression with generalised estimating equation (GEE) analyses were performed to determine the factors associated with APOs.

RESULTS: A total of 153 patients with 240 pregnancies were included and the majority of the patients were Malay (69.9%), followed by Chinese (24.2%) and Indian (5.9%). The prevalence of APOs was 61.7% with the commonest complication being prematurity (28.3%), followed by pregnancy loss (24.6%) and pre-eclampsia (21.8%). Logistic regression model-based GEE analysis revealed that the independent predictors of APOs were active haematological system during pregnancy, pre-pregnancy active disease, Indian patients and positive lupus anticoagulant. Hydroxychloroquine use was associated with lower APOs including pre-eclampsia, prematurity and IUGR in the univariate analyses but it was no longer significant in the GEE analysis.

METHODS: A systematic search was conducted on PubMed, EBSCOHost, and Web of Science. We identified 22 casecontrol studies that matched our inclusion and exclusion criteria. Information such as study characteristics, genetic polymorphisms associated with SLE, and organ manifestations was extracted and reported in this review.

RESULTS: In total, 30 polymorphisms in 16 genes were found to be associated with SLE among Asians. All included polymorphisms also reported associations with various SLE clinical features. The association of rs1234315 in TNFSF4 linking to SLE susceptibility (P=4.17x10-17 OR=1.45 95% CI=1.34-1.59) and musculoskeletal manifestation (P=3.35x10-9, OR=1.37, 95%CI= 1.23-1.51) might be the most potential biomarkers to differentiate SLE between Asian and other populations. In fact, these associated genetic variants were found in loci that were implicated in immune systems, signal transduction, gene expression that play important roles in SLE pathogenesis.
