    In a cross-sectional study of 24 Oriental children with systemic lupus erythematosus (SLE) with a mean age of 11.25 years, 75% were found to have clinical and neurophysiological evidence of cerebral lupus. Seizures were the most common manifestation affecting 11 (61%) of the cases, followed by psychosis in five (27.7%), encephalopathy in five (27.7%), headaches in five (27.7%), personality changes in four (22.2%), stroke in three (16.6%), movement disorders in three (16.6%) and myelitis in one child (5.5%). Four children had cerebral lupus as the presenting manifestation of SLE. Twenty-one children had an electroencephalogram (EEG) of which 11 were normal. Abnormalities detected in the rest included focal sharps, slowing of background and electrodecremental changes. There was a poor correlation of EEG with the clinical presentation. Sixteen children with cerebral lupus had a computed tomogram (CT) of which three were normal. The commonest abnormality was cerebral atrophy with or without infarcts. Only four of the cases had lupus anticoagulant but compliment was reduced in 13. Sixteen of the cases also had renal involvement. Treatment was generally with steroids with only two patients receiving cyclophosphamide for cerebral relapse. Eight children (44%) made a full recovery. Learning disability was the most frequent sequelae affecting one-third of children seen at a 1-year follow up. Four (22%) had epilepsy, two (11%) had motor deficits and one child had optic atrophy. One child died of cerebral haemorrhage during a hypertensive crisis.

    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.

    Chronic intestinal pseudo-obstruction (CIPO) is a rare clinical syndrome of ineffective intestinal motility characterised by clinical and radiological evidence of intestinal obstruction with no identifiable mechanical lesion. CIPO can either be idiopathic or secondary to a systemic disease, like systemic lupus erythematosus (SLE). Fewer than 30 cases of CIPO secondary to SLE have been reported so far. Here we describe a case of SLE with the initial presentation of CIPO. In SLE-related CIPO, treatment includes a combination of high-dose intravenous corticosteroids, immunosuppressants and supportive care. With awareness of this condition, unnecessary surgical intervention and repeated invasive procedures could be avoided. Early initiation of treatment would avoid complications and bring about resolution of symptoms.

    OBJECTIVES: This study examined the correlations of both serum and urine interleukin-17A (IL-17A) levels with disease activity in systemic lupus erythematosus (SLE). This study was also aimed at determining their sensitivity and specificity as biomarkers of disease activity in SLE.

    METHODS: A cross-sectional study was performed involving SLE patients (n = 120 patients) from Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Serum and urinary IL-17A levels were determined by immunoassay while disease activity was assessed using Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K) and British Isles Lupus Assessment Group's 2004 index (BILAG 2004) scores. The correlations between serum and urinary IL-17A levels with total SLEDAI-2K and BILAG 2004 scores were determined using bivariate correlation analyses. Receiver operating characteristic curves were calculated to determine their sensitivity and specificity as disease activity biomarkers.

    RESULTS: Both serum and urinary IL-17A levels correlated with total scores of BILAG 2004, BILAG renal, BILAG mucocutaneous, and SLEDAI-2K (P

    One hundred and two patients attending the systemic lupus erythematosus (SLE) clinic of the Department of Medicine, Universiti Kebangsaan Malaysia, were studied retrospectively to determine their survival rates and causes of death. There were 21 deaths. The 1, 5, and 10 year survival rates were 93%, 86% and 70% respectively. There was a bimodal pattern of mortality with more patients dying in the first 2 years or after 5 years of disease. Infection was the direct cause of death in 52% and contributed to a further 19% of deaths. Patients with lupus nephritis had a higher relative risk (RR) of death (RR = 4.34, p < 0.02) although there was no significant increase in risk with any particular histological type on biopsy. Cerebral lupus (RR = 3.08, p < 0.001) and methylprednisolone treatment (RR = 6.24, p < 0.001) were also associated with increased risk of death. Increased awareness of infection and earlier use of antibiotic therapy may improve survival of patients suffering from SLE.

    To determine the incidence, types and risk factors for infection in systemic lupus erythematosus (SLE) patients in Kuala Lumpur, Malaysia, we retrospectively reviewed the medical records of 102 patients with definite SLE attending a specialist clinic. Details of major infections (pneumonia or severe infection requiring intravenous therapy) and minor infections, and their time of onset in relation to immunosuppressive therapy and disease flares were recorded. There were 77 major and 163 minor infections during 564 patient-years of follow-up. In the month following a course of pulse methylprednisolone, the incidence of major infection was 20 times higher and the incidence of minor infection was 10 times higher than at other periods (p < 0.0001). In the month after disease flare, the incidence of major infection was 10 times higher and the incidence of minor infection six times higher than at other times (p < 0.0001). After allowing for methylprednisolone therapy and disease flares, there was no increase in the rate of infections during treatment with azathioprine, oral or intravenous cyclophosphamide. There was no effect of renal involvement on infection rate.

    During a period of three years (February 1995 --January 1998), 30 biopsies were performed for patients within the paediatric age group in Hospital Universiti Sains Malaysia (HUSM). The majority of these patients (19 cases) had steroid-resistant Nephrotic Syndrome. Other indications were lupus erythematosus (5 cases), acute or chronic glomerulonephritis (5 cases) and infantile nephrotic syndrome (1 case). The biopsy of the 19 cases of steroid-resistant nephrotic syndrome gave the following findings: 10 showed minimal- change nephrotic syndrome, 4 focal segmental glomerulosclerosis, 3 mesangial proliferative glomerulonephritis and one diffuse sclerosing glomerulonephritis while there was insufficient glomeruli for a conclusive diagnosis in one case. The 5 patients with acute/chronic glomerulonephritis showed diffused sclerosing glomerulonephritis. The other 5 patients with lupus nephritis showed mesangial proliferative glomerulonephritis (2) and severe proliferative glomerulonephritis (3). The 5-month-old child with infantile nephrotic syndrome showed mesangial proliferative glomerulonephritis. There were no severe complications noted during or immediately after the procedure. There were 3 cases of gross haematuria, one lasting less than 24 hours and the other two less than

    Heat treatment of sera at 56 degrees C for 30 min results in positive ELISA reactions for anti-cardiolipin antibody (aCL) in sera that had undetectable or low levels of aCL before heat inactivation. The positive, potentiated reactivity of the heated sera in the aCL ELISA could be inhibited with the cardiolipin antigen and was abolished by prior IgG depletion using staphylococcal protein A. The heat-potentiating effect of aCL binding in ELISA was evident in both normal human sera and clinical sera including sera from patients with systemic lupus erythematosus and syphilis.

    Introduction White matter hyperintense (WMHI) lesions are the most common finding in magnetic resonance imaging (MRI) of the brain in patients with systemic lupus erythematosus (SLE). Objective The objective of this article is to determine the clinical factors associated with an increase in WMHI lesion load among SLE patients. Method A total of 83 SLE patients with MRI of the brain from National University of Malaysia Medical Centre were included. The WMHI lesion load was determined using the Scheltens score and Fazekas scale, and their distribution was divided into the deep white matter (DWMHI) and periventricular (PVH) regions. The clinical correlates of WMHI lesions were initially determined using univariate analyses and subsequently multivariable regression analyses were performed to determine the independent factors of increased WMHI lesion load. Results MRI of the brain of 46 patients who had WMHI lesions were compared with 37 patients with normal MRI. We found significant association between the presence of WMHI lesions and age, presence of cerebral infarcts, positive antiphospholipid antibody (aPL), active disease, neuropsychiatric lupus (NPSLE) and disease damage. Age, SLEDAI scores, cerebral infarcts and disease damage were significantly associated with higher DWMHI and PVH Scheltens scores. Meanwhile, patients with active lupus nephritis (LN), lower serum albumin and more severe proteinuria were associated with larger Fazekas WMHI lesions. Multivariable regression analysis revealed that the independent factors associated with presence of WMHI lesions were positive aPL and SLEDAI scores ( p

    We report a 13-year-old girl diagnosed with systemic lupus erythematosus (SLE) who presented with left-sided chest pain, with ECG changes and elevation troponins that were suggestive of an acute inferior wall myocardial infarction (MI). Her multi-slice computed tomography coronary angiogram and standard angiogram were normal. The cardiac magnetic resonance imaging revealed an area of infarcted myocardium that was in the right coronary artery territory. We believe her MI was most likely secondary to coronary vasospasm. MI is rare and coronary vasospasm is an uncommon cause of MI in children and adolescents with SLE.

    BACKGROUND: Vitamin D deficiency is more prevalent among SLE patients than the general population. Over the past decade, many studies across the globe have been carried out to investigate the role of vitamin D in SLE from various clinical angles. Therefore, the aim of this systematic review is to summarise and evaluate the evidence from the published literature; focusing on the clinical significance of vitamin D in SLE.

    METHODS: THE FOLLOWING DATABASES WERE SEARCHED: MEDLINE, Scopus, Web of Knowledge and CINAHL, using the terms "lupus", "systemic lupus erythematosus", "SLE and "vitamin D". We included only adult human studies published in the English language between 2000 and 2012.The reference lists of included studies were thoroughly reviewed in search for other relevant studies.

    RESULTS: A total of 22 studies met the selection criteria. The majority of the studies were observational (95.5%) and cross sectional (90.9%). Out of the 15 studies which looked into the association between vitamin D and SLE disease activity, 10 studies (including the 3 largest studies in this series) revealed a statistically significant inverse relationship. For disease damage, on the other hand, 5 out of 6 studies failed to demonstrate any association with vitamin D levels. Cardiovascular risk factors such as insulin resistance, hypertension and hypercholesterolaemia were related to vitamin D deficiency, according to 3 of the studies.

    CONCLUSION: There is convincing evidence to support the association between vitamin D levels and SLE disease activity. There is paucity of data in other clinical aspects to make firm conclusions.

    Avascular necrosis of bone (AVN) is increasingly being recognized as a complication of SLE and causes significant disability due to pain and mobility limitations. We studied the prevalence and factors associated with avascular necrosis (AVN) in a multiethnic SLE cohort. SLE patients who visited the outpatient clinic from October 2017 to April 2019 were considered eligible. Their medical records were reviewed to identify patients who developed symptomatic AVN, as confirmed by either magnetic resonance imaging or plain radiography. Subsequently, their SLE disease characteristics and treatment were compared with the characteristics of patients who did not have AVN. Multivariable logistic regression analyses were performed to determine the independent factors associated with AVN among the multiethnic SLE cohort. A total of 390 patients were recruited, and the majority of them were females (92.6%); the patients were predominantly of Malay ethnicity (59.5%), followed by Chinese (35.9%) and Indian (4.6%). The prevalence of symptomatic AVN was 14.1%, and the mean age of AVN diagnosis was 37.6 ± 14.4 years. Both univariate and multivariable logistic regression analyses revealed that a longer disease duration, high LDL-C (low density lipoprotein cholesterol), positive anti-cardiolipin (aCL) IgG and anti-dsDNA results, a history of an oral prednisolone dose of more than 30 mg daily for at least 4 weeks and osteoporotic fractures were significantly associated with AVN. On the other hand, hydroxychloroquin (HCQ), mycophenolate mofetil (MMF) and bisphosphonate use were associated with a lower risk of AVN. No associations with ethnicity were found. In conclusion, several modifiable risk factors were found to be associated with AVN, and these factors may be used to identify patients who are at high risk of developing such complications. The potential protective effects of HCQ, MMF and bisphosphonates warrant additional studies.

    BACKGROUND: Hospital admissions and re-admissions in lupus patients are common occurrences that can lead to poor prognosis.

    OBJECTIVES: We evaluated the leading causes of all-cause hospitalizations and their predictive factors in the Malaysian multi-ethnic SLE patients.

    METHODS: This is a retrospective study involving 300 SLE patients. Demographic data and details of hospitalizations from the year 1988 until 2019 were reviewed. Baseline and latest disease activity (SLEDAI-2 K) and SLICC/ACR damage index (SDI) scores were evaluated. To be eligible for this study, their SLE diagnosis and disease duration was at least one year; this is to ensure that the baseline disease damages were measured at least after 6 months of diagnosis and subsequent disease damage indexes were captured.

    RESULTS: Majority were of Chinese ethnicity 150 (50%). The cohort's median age was 48 (18-82) years and median disease duration was 13 (1-52) years. 133 (44.3%) had SDI score of ≥1 at baseline (early damage). 69 (23%) had developed new organ damage during this study period.There were 222 (74%) patients ever hospitalized from this cohort. The main cause of hospitalization was lupus flare which included concurrent infection (n = 415 admissions, 46%), followed by elective admissions for procedures and others (n = 284 admissions, 31.5%). Admissions for treatment and disease related complications were 13.8%. 8.7% of admissions were due to infections alone. Median length of stay for SLE-related cause admissions was longer compared to non-SLE related causes. Jointly predictive factors for hospitalization were anti-phospholipid syndrome (OR 5.82), anti-Smith (OR 6.30), anti-SSA (OR 3.37), serositis (OR 14.56), neurological (OR 5.52) and high baseline SDI (OR 1.74), all p

    The frequency of the HLA class II antigens/alleles (HLA-DR, DQ and DP) were studied in 70 Malaysian Chinese patients with systemic lupus erythematosus (SLE) to examine the contribution of these genes to disease susceptibility, their clinical expression and Immunological responses. This was done using modified PCR-RFLP technique. These samples were then compared with 66 ethnically matched controls. We found a strong association of the DQA1*0102 (p corr = 0.032, rr = 3.39), DQB1*0501 (p corr = 0.003, rr = 4.55), *0601 (p corr = 0.006, rr = 4.22) and DPB1* 0901(p corr = 0.02, rr = 4.58) with SLE. Clinically, we found a strong association of DR2 and DQA1*0301 with renal involvement and DQA1*0102 with alopecia. Immunologically, statistical analysis (Chi-square test ) showed a strong association of DQA1*0102 with anti-Ro/La antibodies while DQA1*0301 was observed to be strongly associated with antibodies to ds DNA. DQA1*0102 was found more frequently in those with a later disease onset (30 years of age or above). From these data we suggest that the HLA class II genes play a role in conferring disease susceptibility and clinical and immunological expression.

    An analysis of the clinical and serological features of 12 male and 122 female patients with SLE was done to determine whether sex related differences exist. We found a lower incidence of mucocutaneous symptoms and arthritis but an increased incidence of discoid lesions, pleuritis and pericarditis in males at disease onset. During the disease course, there was a lower incidence of arthritis, a similar prevalence of mucocutaneous symptoms but an increased incidence of pleuritis in males with a trend towards renal involvement. These findings were however not statistically significant except for the higher incidence of thrombosis among males. Serologically, both groups showed similar frequencies of autoantibodies and hypocomplementaemia. Although the study was small, it was shown that several sex-related differences in the clinical and serological features exist in Malaysian SLE patients.

    BACKGROUND: Studies have shown that certain genes within the major histocompatibility complex predispose to systemic lupus erythematosus (SLE) and may influence clinical and autoantibody expression. Thus, we studied the frequency of HLA-DR, -DQA, -DQB and -DPB alleles in ethnic Malays with SLE to determine the role of these genes in determining disease susceptibility and their association with clinical and immunological manifestations.
    METHODS: Fifty-six Malay SLE patients were enrolled into the study. Demographic, clinical and immunological findings were obtained from medical records. HLA-DR, DQ and DP typing were done using modified PCR-RELP. Controls were from ethnically-matched healthy individuals.
    RESULTS: We found a strongly significant association of the DR2 and DQB1 *0501 and DQB1*0601 (pcorr = 0.03, rr = 3.83, pcorr = 0.0036, rr = 4.56 and pcorr = 0.0048 and rr = 6.0, respectively). There was also a weak increase of DQB1*0.201 and DPB1*0.0901 with a weak decrease of DQA1*0601 and DQB1*0503 and *0301 which were not significant after corrections for multiple comparisons were made. There was a significant positive association of DR2 and DQB1*0501 with renal involvement and DR8 with alopecia. A nonsignificant increase of DQB1*0503 in patients with photosensitivity was noted. Significant autoantibody associations were also found: DQB1*0601 with anti-Sm/RNP, DR2 with antiSSA (Ro)/SSB (La), and DR2, DQB1*0501 and *0601 with antibodies to ds DNA. There was no specific DR, DQ or DP associations with age of disease onset (below 30 years or those at or above 30 years).
    CONCLUSION: Our data suggests the role of the HLA class II genes in conferring SLE susceptibility and in clinical and autoantibody expression.

    Objective: SLE is an autoimmune disease which affects multiple organ system. Clinical and immunological expression of the disease have been widely studied and variations occur in different ethnic groups. Here in this study, we have analyzed the clinical manifestations and immunological features of Malaysian patients with Systemic lupus erythematosus (SLE) and compared them with SLE population from some of the Asian countries. Study design: A total of 134 Malaysian patients attending the SLE Clinic of The National University Hospital of Malaysia, Kuala Lumpur and who satisfy the revised ACR (American College of Rheumatology) criteria for the classification of SLE were enrolled into the study. Data on the demography, clinical and immunological features were obtained from medical records. Materials and Methods: The female to male ratio in the study cohort was 10:1 and consisted of the Malay, Chinese and Indian races. Past clinical and immunological features were entered into a prepared questionnaire. At study entry patients were seen by a rheumatologist for assessment of present clinical condition and blood obtained for immunological tests (Antinuclear, antids DNA, antiSm, antiU1RNP, antiSSA(Ro), antiSSB(La), anticardiolipin (IgG and IgM) antibodies and complements C3 and C4). Chi-square, Fisher's exact test and Mann Whitney U Test were used to analyze data. Results: Clinical features expressed at disease presentation in order of frequency was mucocutaneous (72%), followed by musculoskeletal (58%) and renal involvement (45%) which was also similar during the course of the disease (90%, 72% and 64% respectively). A high prevalence of antiSSB (La) antibodies was found (48%). Conclusion: This study provides the literature on the clinical and immunological features of Malaysian SLE patients and further shows the different spectrum of disease profile when compared to other ethnic groups. The roles of racial and genetic factors are suggested.

    Objective: The frequency of the HLA class II antigens (HLA DR, DQ and DP) were determined among Malay patients with systemic lupus erythematosus (SLE) to ascertain the role they play in disease susceptibility. Study design: Fifty-six Malay SLE patients on follow-up at the SLE Clinic of the National University of Malaysia Hospital, Kuala Lumpur were enrolled into the study. Controls were taken from healthy unrelated individuals, ethnically-matched. Materials and Methods: Five ml of anticoagulated blood was taken from each patient and control and DNA extracted. The HLADR, DQ and DP antigen/allele frequencies were determined by the technique of modified PCR-RFLP and statistical analysis done by Chi-square and Fischers exact test. Relative risk was determined by the odds ratio and significant p values were corrected for the number of antigens/alleles tested. Results: We found that the DR2 antigen was significantly increased among the patients (85.7%) as compared to controls (61%)(p corr=0.03, RR=3.83). As for HLA-DQA1, the allele most commonly found among the patients was *0102 (57 vs 49.2%). HLA-DQA1* 0601 was slightly decreased among the patients but this finding was insignificant. Both HLA-DQB1*0501 and 0601 were found to be increased among the patients even after correction of multiple comparisons made (p=0.0036, RR=4.56 and p=0.0048, RR=6.0, respectively). However, HLA-DQB1*0503 and 0301 was slightly decreased in the sle patients though not statistically significant. The frequency of HLA-DQB1*0201 was insignificantly increased among the patients. Limited studies on the DPB1 locus shows the uncertain role of this antigen in contributing to disease susceptibility. However, our analysis of the HLA-DPB1*0901 showed a slight increase among the patients as compared to controls but failed to remain significant after being corrected with number of comparisons made. All other HLA-DPB1 alleles exhibited similar frequencies between sle patients and controls. Conclusion: From this study we suggest that HLA DR2, DQB1*0501 and *0601 may be important genetic factors in conferring disease susceptibility in the Malay SLE population of Malaysia.
