PMID: 3452712

In the 12-year period between 1974 and 1985, 19 children aged between 8 and 12 years with systemic lupus erythematosus (SLE) were seen in the Department of Paediatrics, University Hospital, Kuala Lumpur. A preponderance of females (M:F = 1:2.8) and ethnic Chinese was evident. Renal biopsies revealed a wide Iange of renal morphology, including minimal change glomerulonephritis, focal proliferative glomerulonephritis, diffuse proliferative glomerulonephritis with varying degrees of severity and membranous glomerulonephritis. The majority (15) of patients had clinical SLE at the time of renal biopsy, of whom 4 were also grossly nephrotic. In the remaining 4 patients a diagnosis of SLE was made after further investigation for nephrotic syndrome (2) and acute nephritis (2). The pattern of renal pathology in childhood lupus nephritis appears not to differ significantly from adults.

PMID: 3241577

Between 1980-1986, 219 renal biopsies were performed on patients with lupus nephritis (LN) presenting at the General Hospital, Kuala Lumpur. There were 172 (78.5%) females and 47 (21.5%) males. The ethnic distribution of 48.4% Malays, 46.1% Chinese and 5.5% Indians reflected their proportional composition in the general population. Peak incidence (40.6%) of cases occurred in the third decade of life (20-29 group) followed by 26.5% and 20.1% in the second and fourth decades respectively. The median age was 24 for females and 27 for males. In both sexes, nephrotic syndrome was the commonest mode of presentation (62.2%) followed by proteinuria (20.5%). Acute oliguric renal failure occurred in 11 patients (5%) and 8 of these showed crescentic glomerulonephritis with more than 50% crescents. The commonest histological picture was diffuse proliferative LN (WHO Stage IV-44.7%) which included 70% (19/27) of those with crescentic disease. This was followed by membranous LN (28.8%) of which 6 (all males) had crescentic disease. 7 (12.3%) of our patients had crescentic nephritis with a female to male distribution of 14: 13, suggesting either more aggressive disease or delayed diagnosis in males.

Renal biopsy is essential in the management of renal parenchymal diseases. Thus far there is no publish report on the pattern of glomerulonephritis in Kelantan. We decided to establish the pattern of glomerulonephritis in Kelantan and use this information as our reference in future studies. Records of patients who had proven glomerulonephritis histologically were analysed. Their biological data, clinical presentation, etiology and clinicopathological pattern were studied. Where appropriate mean and standard deviation were calculated. A total of 74 biopsies were performed during the study period (between January 1991 and December 1993), out of which 72 biopsies (97.3%) were considered suitable for analysis. The male to female ratio was 1:1.1. Mean age at presentation was 27.6 +/- 12.2 years. Nephrotic syndrome was the commonest clinical presentation (65.3%). The main underlying cause was systemic lupus erythematosus (50%) followed by primary glomerulonephritis. Histologically, IgA nephropathy and minimal change disease were the main patterns among patients with primary glomerulonephritis while diffuse proliferative glomerulonephritis was the commonest pattern among patients with lupus nephritis. Hence the pattern of glomerulonephritis is similar to other reported series. The procedure is considered safe and has a high success rate.

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.

Longitudinal associations of active renal disease with irreversible organ damage accrual in systemic lupus erythematosus

Kandane-Rathnayake R, Kent JR, Louthrenoo W, Luo SF, Wu YJ, Lateef A, et al.

Lupus, 2019 Dec;28(14):1669-1677.
PMID: 31718467 DOI: 10.1177/0961203319887799

OBJECTIVE: To examine longitudinal associations of active lupus nephritis with organ damage accrual in patients with systemic lupus erythematosus (SLE).
METHODS: This study was performed using data from a large multinational prospective cohort. Active lupus nephritis at any visit was defined by the presence of urinary casts, proteinuria, haematuria or pyuria, as indicated by the cut-offs in the SLE Disease Activity Index (SLEDAI)-2K, collected at each visit. Organ damage accrual was defined as a change of SLICC-ACR Damage Index (SDI) score >0 units between baseline and final annual visits. Renal damage accrual was defined if there was new damage recorded in renal SDI domains (estimated glomerular filtration rate <50%/proteinuria >3.5 g per 24 h/end-stage kidney disease). Time-dependent hazard regression analyses were used to examine the associations between active lupus nephritis and damage accrual.
RESULTS: Patients (N = 1735) were studied during 12,717 visits for a median (inter-quartile range) follow-up period of 795 (532, 1087) days. Forty per cent of patients had evidence of active lupus nephritis at least once during the study period, and active lupus nephritis was observed in 3030 (24%) visits. Forty-eight per cent of patients had organ damage at baseline and 14% accrued organ damage. Patients with active lupus nephritis were 52% more likely to accrue any organ damage compared with those without active lupus nephritis (adjusted hazard ratio = 1.52 (95% confidence interval (CI): 1.16, 1.97), p

INTRODUCTION: Renal involvement is the most common serious complication in patients with systemic lupus erythematosus (SLE).
OBJECTIVE: The objective of this article is to investigate and determine the associated factors of disease damage among lupus nephritis (LN) patients.
METHODS: Medical records of LN patients who attended regular follow-up for at least one year in the Nephrology/SLE Clinic, Universiti Kebangsaan Malaysia Medical Centre (UKMMC), were reviewed. Their Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) Damage Index scores were noted. Univariate analysis and multivariable regression analysis were performed to determine the independent factors of disease damage in LN.
RESULTS: A total of 150 patients were included and their follow-up duration ranged from one to 20 years. Sixty (40%) LN patients had disease damage (SDI ≥1). In the univariate analysis, it was associated with age, longer disease duration, antiphospholipid syndrome (APS), higher maximum daily oral prednisolone dose (mg/day), lower mean C3 and C4, higher chronicity index and global sclerosis on renal biopsies (p < 0.05). Patients who received early (≤3 months after the SLE diagnosis) hydroxychloroquine (HCQ), optimum HCQ dose at 6.5 mg/kg/day and achieved early complete remission (CR) were less likely to have disease damage (p < 0.05). After adjustment for age, gender, disease duration and severity, multivariable regression analysis revealed that a higher maximum daily dose of oral prednisolone was independently associated with disease damage while early HCQ and CR were associated with lower disease damage.
CONCLUSION: Higher maximum daily prednisolone dose predicted disease damage whereas treatment with early HCQ and early CR had a protective role against disease damage.

Thickened carotid intima media thickness and carotid atherosclerosis among lupus nephritis patients: the role of traditional and lupus-specific factors

Sazliyana S, Mohd Shahrir MS, Kong NC, Tan HJ, Hamidon BB, Azmi MT

Int J Rheum Dis, 2011 Aug;14(3):267-75.
PMID: 21816023 DOI: 10.1111/j.1756-185X.2011.01638.x

AIM: The objectives of this study were to investigate the frequency of thickened carotid intima media thickness (CIMT) and atherosclerosis among lupus nephritis (LN) patients and to study their associated risk factors.
METHOD: In this cross-sectional study, carotid ultrasonography was performed on consecutive LN patients to determine CIMT and presence of carotid plaques. CIMT was considered to be abnormally thickened if it was more than the 75th percentile matched for age and sex from the 'Carotid Atherosclerosis Progression Study'. The association between thickened CIMT with traditional cardiovascular risk factors and lupus characteristics were examined. A total of 83 patients with the mean age of 33.6 ± 10 years were recruited.
RESULTS: Fourteen patients (16.9%) had thickened CIMT and three (3.6%) had carotid plaques. On univariate analysis, traditional risk factors significantly associated with thickened CIMT (P < 0.05) were patient's current age, diabetes mellitus and waist circumference. Meanwhile, a lower serum C4 levels and higher serum C-reactive protein levels were the lupus-specific factors associated with thickened CIMT (P < 0.05, P < 0.05 and P < 0.01, respectively). In logistic regression analysis, the independent predictors of thickened CIMT were age of diagnosis, lower serum C4 levels and waist circumference (P < 0.05).
CONCLUSION: More lupus specific factors were independently associated with thickened CIMT, suggesting that a multi-targeted approach of treatment addressing both the lupus and traditional cardiovascular risks are very important. Larger prospective studies of these special risk factors are indicated.
