    Following the opening of the University Hospital of the University of Malaya in 1967, over 126,000 patients (excluding obstetric patients) have been admitted. A retrospective review, run concurrently with a prospective study, of over 200 patients thought to have suffered from systemic lupus erythematosus (SLE) revealed that, up until the 31st December 1975, 175 patients fulfilled the criteria for the diagnosis of SLE. There was a highly significant increase in the diagnosis of SLE over this period among Chinese patients compared to all other races, and no significant differencein the diagnosis of SLE among Indian and Malay patients. A review of the literature revealed that SLE appears to be a worldwide disease, reported frequently from Chinese communities but infrequently from tropical Africa. It is concluded that SLE is more common in the Chinese from Peninsular Malaysia than the other races, and that a careful study of geographical and racial factors in SLE may contribute to further understanding of its pathogenesis.

  3. Fulltext Frequency and predictors of the lupus low disease activity state in a multi-national and multi-ethnic cohort
    Golder V, Kandane-Rathnayake R, Hoi AY, Huq M, Louthrenoo W, An Y, et al.
    Arthritis Res Ther, 2016 11 09;18(1):260.

    BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic heterogeneous disease with considerable burden from disease activity and damage. A novel clinical treatment target in the form of the lupus low disease activity state (LLDAS) has been recently reported, with retrospective validation showing that time spent in LLDAS translates to reduced damage accrual. The objectives of this study were to describe the frequency and identify the predictors of attaining LLDAS in a large multinational cohort of patients with SLE.
    METHODS: Data were collected at the recruitment visit in patients with SLE enrolled in a longitudinal study in nine countries. Data were analysed cross-sectionally against the recently published definition of LLDAS, and the frequency and characteristics associated with presence of LLDAS were determined. Stepwise multivariable logistic regression was used to determine predictors of LLDAS.
    RESULTS: Of the 1846 patients assessed, criteria for LLDAS were met by 44 %. Patients with shorter disease duration were less likely to be in LLDAS (OR 0.31, 95 % CI 0.19-0.49, p

    Ann Rheum Dis, 1980 Jun;39(3):266-9.
    PMID: 7416817 DOI: 10.1136/ard.39.3.266
    In the first 9 years following the opening of the University Hospital in kuala Lumpur nearly 130,000 patients have been admitted (excluding obstetric patients), and, of these, 175 fulfilled the American Rheumatism Association criteria for the diagnosis of systemic lupus erythematosus. This diagnosis was made significantly more frequently in Chinese patients than in other races. SLE is more often reported from Chinese communities in Asia than from India and tropical Africa. There may be a lower susceptibility to autoimmune disease in black Africans than the suspected increased susceptibility to autoimmune disease in black Africans than the suspected increased susceptibility in their American Negro and West Indian descendants. A careful study of racial and geograhical factors in autoimmune disease should throw further light on the interaction between the host and his environment which results in autoimmune disease.

    OBJECTIVE: Peripheral neuropathy in systemic lupus erythematosus (SLE) is heterogeneous and its commonest pattern is symmetrical polyneuropathy. The aim of this study was to describe the prevalence, clinical and electrophysiological features, disease associations and effects on function and quality of life of polyneuropathy in SLE patients, defined using combined clinical and electrophysiological diagnostic criteria.
    METHODS: Consecutive SLE patients seen at the University of Malaya Medical Centre were included. Patients with medication and other disorders known to cause neuropathy were excluded. Demographic, clinical and laboratory data were obtained using a pre-defined questionnaire. Function and health-related quality of life was assessed using the modified Rankin scale and the SF-36 scores. Nerve conduction studies (NCS) were carried out in both upper and lower limbs. Polyneuropathy was defined as the presence of bilateral clinical symptoms and/or signs and bilateral abnormal NCS parameters.
    RESULTS: Of 150 patients, 23 (15.3%) had polyneuropathy. SLE-related polyneuropathy was mainly characterized by sensory symptoms of numbness/tingling and pain with mild signs of absent ankle reflexes and reduced pain sensation. Function was minimally affected and there were no differences in quality of life scores. NCS abnormalities suggested mild length-dependent axonal neuropathy, primarily in the distal lower limbs. Compared to those without polyneuropathy, SLE-related polyneuropathy patients were significantly older but had no other significant demographic or disease associations.
    CONCLUSIONS: SLE-related polyneuropathy is a chronic, axonal and predominantly sensory neuropathy, associated with older age. Its underlying pathogenetic mechanisms are unknown, although a possibility could be an increased susceptibility of peripheral nerves in SLE patients to effects of aging.

  6. Lupus organ damage: what is damaged in Asian patients?
    Kuan WP, Li EK, Tam LS
    Lupus, 2010 Oct;19(12):1436-41.
    PMID: 20947554 DOI: 10.1177/0961203310370050
    Assessment of organ damage has become the standard outcome measure for morbidity and mortality in patients with lupus. Ethnicity is thought to be a marker for genetic, environmental, behavioral, and other variables that may affect disease outcomes. Previous studies suggest that Asians residing in western countries had significantly higher prevalence of damage compared with Whites. In contrast, studies performed in Chinese, Korean and Arab patients showed that the overall prevalence of damage and the most commonly involved organs (neuropsychiatric and musculoskeletal) were similar to Whites. Compared with their Asian counterparts, Pakistani and Jewish patients appeared to have a higher prevalence of damage, most likely secondary to longer disease duration. Chinese patients had an increased prevalence of premature gonadal failure, whereas patients residing in western and southern Asia had more skin damage. When compared with Whites, Asian patients had more renal damage but less ocular and cardiovascular damage. Risk factors associated with organ damage in Asian lupus patients included older age, higher disease activity, and the use of cyclophosphamide and steroids. Further investigations into other determinants such as genetic predisposition, socioeconomic factors, prevalence and severity of disease manifestations, and treatment, is needed in order to understand the variation in damage accrual in lupus patients from different ethnicities.

    PMID: 10392744
    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.

    Med J Malaysia, 1995 Mar;50(1):25-31.
    PMID: 7752972
    Between January 1976 and December 1992, 17 patients on follow-up at Systemic Erythematosus (SLE) Clinic in the University Hospital, Kuala Lumpur had onset of the disease after the age of 50 years. This constituted about 4% of our total SLE patients. They formed a distinct subgroup of the lupus population with an insidious onset and have a benign course compared to the younger SLE patients. Arthritis and skin rashes were the commonest initial manifestations. Renal and central nervous system manifestations were uncommon but pulmonary involvement was frequent compared to young SLE patients. The prevalence of positive autoantibodies and hypocomplementaemia were lower. Disease activity showed no correlation with erythrocyte sendimentation rate, autoantibodies or complement levels. Overall prognosis in these late-onset patients was favourable with a good response to steroids and less frequent relapses.

  9. Maternal and perinatal outcomes of pregnancies in systemic lupus erythematosus: A nationwide population-based study
    Chen YJ, Chang JC, Lai EL, Liao TL, Chen HH, Hung WT, et al.
    Semin Arthritis Rheum, 2020 06;50(3):451-457.
    PMID: 32115237 DOI: 10.1016/j.semarthrit.2020.01.014
    OBJECTIVES: Systemic lupus erythematosus (SLE) is an autoimmune disease that develops mainly in women of reproductive age. We aimed to explore the risk of pregnancy complications in Asian patients with SLE.

    METHODS: From January 2005 to December 2014, we conducted a nationwide case-control study, using Taiwan's National Health Insurance Research Database. Obstetric complications and perinatal outcomes in SLE patients were compared with those without SLE.

    RESULTS: 2059 SLE offspring and 8236 age-matched, maternal healthy controls were enrolled. We found increased obstetric and perinatal complications in SLE population compared with healthy controls. SLE patients exhibited increased risk of preeclampsia/eclampsia (8.98% vs.1.98%, odds ratio [OR]: 3.87, 95% confidence interval [95% CI]: 3.08-4.87, p<0.0001). Their offspring tended to have lower Apgar scores (<7) at both 1 min (10.7% vs. 2.58%, p<0.0001) and 5 min (4.25% vs. 1.17%, p<0.0001), as well as higher rates of intrauterine growth restriction (IUGR, 9.91% vs. 4.12%, OR: 2.24, 95% CI: 1.85-2.71, p<0.0001), preterm birth (23.70% vs 7.56%, OR: 3.00, 95% CI: 2.61-3.45, p<0.0001), and stillbirth (4.23% vs. 0.87%, OR: 3.59, 95% CI: 2.54-5.06, p<0.0001). The risks of preterm birth and stillbirth were markedly increased in SLE patients with concomitant preeclampsia/eclampsia or IUGR. Preterm birth of SLE patients was 1~4 gestational weeks earlier than that of healthy controls and the peak occurrence of stillbirth in SLE population was at 20~30 gestational weeks.

    CONCLUSIONS: Asian SLE patients exhibited increased risks of maternal complications and adverse birth outcomes. Frequent antenatal visits before 20 gestational weeks are recommended in high-risk SLE patients.

    PLoS One, 2021;16(3):e0248845.
    PMID: 33739994 DOI: 10.1371/journal.pone.0248845
    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.

    PMID: 28952322 DOI: 10.1177/0333102417694881
    Background The occurrence of antiphospholipid antibodies (aPLs) and headache comorbidity in the presence or absence of underlying autoimmune diseases remains unclear. Aim The aim of this review was to summarize the relationship between headache and aPLs based on evidences from cohort studies and case reports, in addition to examining the treatment strategies that resolved headache in aPLs-positive individuals.
    Methods A comprehensive literature search was conducted through PubMed, ISI Web of Science and Google Scholar. A total of 559 articles were screened and the appropriate articles were selected based on quality and level of evidence.
    Results Cohort studies (n = 27) from Europe, North America and Asia demonstrated comorbidity of aPLs and headache in antiphospholipid syndrome, systemic lupus erythematosus (SLE) and neuropsychiatric SLE patients. Significantly higher association between migraine and aPLs was observed (n = 170/779; p

    Lupus, 2013 Aug;22(9):967-71.
    PMID: 23846232 DOI: 10.1177/0961203313496299
    OBJECTIVES: Ethnic differences in systemic lupus erythematosus (SLE) have been previously described in the multiethnic Malaysian population. However, there have since been many demographic and socioeconomic changes in the country. The aim of this study is to re-examine the clinical and immunological profiles of Malaysian SLE patients of different ethnic backgrounds.
    METHODS: Consecutive follow-up patients at the University Malaya Medical Centre (UMMC) from July 2010 until March 2011 were included in the study.
    RESULTS: The most common clinical manifestations were malar rash (61.3%), arthritis (52.3%), haematological disease (51.6%), oral ulcers (51%) and renal disease (40.6%). Ethnic Indians had fewer malar and discoid rashes but were at higher risk of arthritis, serositis, renal and neuropsychiatric disease compared to Malays and Chinese Malaysians. Antiphospholipid syndrome (APS) was less common in Chinese. A longer duration of SLE correlated with a lower SLEDAI score.
    CONCLUSION: Overall, the spectrum disease expression was similar to the earlier Malaysian study but the frequency of the more severe disease manifestations, viz. renal, haematological, neuropsychiatric involvements and serositis, were lower. This study further emphasises differences primarily between ethnic Indians and the other races in Malaysia.

    PMID: 9104731 DOI: 10.1177/096120339700600306
    The aims of this study were to examine the clinical and laboratory features of Malaysian patients with systemic lupus erythematosus (SLE) and to identify any difference in disease expression between the different genders and among the three major ethnic groups of Malaysia. Retrospective analysis of all patients with SLE admitted to and followed-up at University Hospital Kuala Lumpur from 1974-90 was undertaken. Ethnic Chinese had the highest prevalence of SLE compared to other ethnic groups. There was a high incidence of renal disease, 74% of patient had significant proteinuria and half of these had associated nephrotic syndrome. Indian patients had significantly less incidence of skin manifestation compared to other racial groups. No difference in disease expression was detected between the ethnic Chinese and Indians and between the male and female patients. The overall 5 y and 10 y survival rates were 82% and 70% respectively. Indian patients had the poorest survival rates. Survival rates are similar among the Chinese and Malay patients. Our findings are in broad agreement with those previously reported.

    All 79 patients who attended a University Systemic Lupus Erythematosus (SLE) Clinic over a 6 month period were assessed using the Clinical Interview Schedule for psychiatric disorder. Using the ICD-9 Classification, 40 were found to have psychiatric disorder, 26 having depressive neurosis, six anxiety neurosis, five endogenous depression and three dementia. The group with psychiatric disorder had significantly poor family support as well as lack of a confidant compared to the group without psychiatric disorder (P < 0.01). There was no difference between the group with psychiatric disorder and those without psychiatric disorder in terms of age, duration of illness, ethnicity and severity of SLE. Psychiatric disorder is common affecting more than half the subjects and depression was the most frequent diagnosis.

    Flare of Systemic Lupus Erythematosus (SLE) may occur during pregnancy and puerperium. We studied the prevalence and factors associated with SLE relapse during pregnancy and post-partum period in a multi-ethnic SLE cohort. Consecutive SLE patients who attended the outpatient clinic were reviewed for previous history of pregnancies in our institution. Patients who had a complete antenatal, delivery, and post-partum follow up were included. Their medical records were retrospectively analysed to assess the disease activity at pre-pregnancy/conception, during antenatal, and post-partum period. Presence of flare episodes during pregnancy and puerperium were recorded. The pregnancy outcomes recorded include live birth, foetal loss, prematurity and intra-uterine growth restrictions (IUGR). Univariate and multivariable logistic regression with generalized estimating equations (GEE) analyses were performed to determine the factors associated with disease relapse and the pregnancy outcomes. A total of 120 patients with 196 pregnancies were included, with a live birth rate of 78.6%. Four (2.0%) were diagnosed to have SLE during pregnancy. The flare rate in pregnancy was 40.1% while post-partum 17.4%. Majority of the relapse in pregnancy occurred in haematological system (62.3%) followed by renal (53.2%), musculoskeletal (22.1%), and mucocutaneous (14.3%). In GEE analyses, active disease at conception was the independent predictor of SLE relapse during and after pregnancy, whereas older maternal age and Malay ethnicity were associated with higher flare during post-partum. HCQ use was significantly associated with reduced risk of flare in univariate analysis but it was no longer significant in the GEE analyses. Presence of disease flare in pregnancy was significantly associated with prematurity. In conclusion, pregnancy in SLE need to be planned during quiescent state as pre-pregnant active disease was associated with disease relapse in both during and after pregnancy. Malay patients had an increased risk of post-partum flare but further larger prospective studies are needed to confirm the association between pregnancies in the different ancestral background.

    Regulated on activation, normal T-cell expressed and secreted (RANTES) and stromal cell-derived factor 1 (SDF-1) are members of the CC- and CXC-chemokine families, respectively. Both genes have been postulated to be involved in the pathogenesis of systemic lupus erythematosus (SLE). We analyzed position 28 of the RANTES gene promoter region, as well as the SNP observed in the 3' UTR of the SDF-1 gene at position 801, in 130 patients presenting SLE at the Malaya University Medical Centre. Screening of 130 healthy volunteer controls using RFLP was also performed. RANTES-28 polymorphism analysis showed no significant (P = 0.3520) relationship, even though homozygous C/C was more frequent in SLE patients (OR = 1.4183) and heterozygous C/G was more frequent in healthy controls (OR = 0.7051). There were no significant (P = 0.2650) associations between A/A (OR = 0.783), G/G (OR = 1.5914) and G/A (OR = 0.8289) genotypes in the SDF-1 gene polymorphism with SLE. We conclude that there is no significant association of RANTES-28 and SDF-1 gene polymorphisms and occurrence of SLE in Malaysia.

    SLE is an autoimmune disease that is not uncommon in Malaysia. In contrast to Malays and Indians, the Chinese seem to be most affected. SLE is characterized by deficiency of body's immune response that leads to production of autoantibodies and failure of immune complex clearance. This minireview attempts to summarize the association of several candidate genes with risk for SLE in the Malaysian population and discuss the genetic heterogeneity that exists locally in Asians and in comparison with SLE in Caucasians. Several groups of researchers have been actively investigating genes that are associated with SLE susceptibility in the Malaysian population by screening possible reported candidate genes across the SLE patients and healthy controls. These candidate genes include MHC genes and genes encoding complement components, TNF, FcγR, T-cell receptors, and interleukins. However, most of the polymorphisms investigated in these genes did not show significant associations with susceptibility to SLE in the Malaysian scenario, except for those occurring in MHC genes and genes coding for TNF-α, IL-1β, IL-1RN, and IL-6.

    We performed a cross-sessional study of all systemic lupus erythematosus (SLE) pregnancies during a 4-year period (2006-2009) to describe the clinical features, maternal and foetal outcomes in our centre. There were 48 pregnancies in 44 women with SLE. Our patients have a mean age of 30.0 years (SD 6.36) and a mean disease duration of 40.67 months (SD 48.23). Our patients have complicated pregnancies: 32.7% have SLE flares, 17.3% have preeclampsia and 48.9% needed caesarean sections. There were 20.0% foetal losses and 17.8% preterm deliveries in our patients. SLE flares contributed to 60.0% of foetal losses in our patients. Lupus pregnancies in our centre generally have a good maternal and foetal outcome comparable to developed countries in Asia. The low incidence of APS, the high usage of hydroxychloroquine and the high SLE remission rate in our patients prior to conceptions contributed to the good outcome.

    PMID: 12223986 DOI: 10.1007/s100670200102
    The aim of this study was to investigate the incidence of IgG anticardiolipin antibody (ACL) and IgG anti-beta(2) glycoprotein I antibody (anti-beta2GPI) positivity in patients with primary or secondary antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE), to assess the association between IgG ACL and anti-beta2GPI, and the relationship between the presence of ACL and anti-beta2GPI with the clinical manifestations of APS. IgG ACL and IgG anti-beta2GPI levels were measured in 51 SLE patients, 20 patients with SLE and APS (secondary APS) and 11 primary APS patients using commercially available ELISA kits. Relationships between laboratory data and clinical manifestations of the patients were examined. The incidence of IgG ACL positivity was significantly higher in primary (36.4%) and secondary (40%) APS than in SLE (13.7%) patients (P = 0.02). The incidence of IgG anti-beta2GPI positivity was significantly higher in primary (54.5%) and secondary (35%) APS than in SLE (7.8%) patients (P = 0.0006). Mean levels of IgG ACL and anti-beta2GPI were significantly higher in the primary and secondary APS than in the SLE patients (P = 0.002 for both). A significant relationship was found between IgG ACL and IgG anti-beta2GPI (P = 0.01, R(2) = 0.56). There was a significant correlation between the presence of IgG ACL and a history of thrombosis in the combined primary and secondary APS group, but not in SLE patients. In conclusion, in this study IgG ACL and IgG anti-beta2GPI are closely related and mean levels of IgG ACL and IgG anti-beta2GPI are higher in patients with either primary or secondary APS than in SLE patients.
