Poor dietary intake is commonly associated with malnutrition in the dialysis population and oral nutritional supplementation is strategized to redress dietary inadequacy. Knowledge on clinical efficacy of whey protein supplementation (WPS) as an option to treat malnutrition in continuous ambulatory peritoneal dialysis (CAPD) patients is limited.. This multicenter, parallel, open-label, randomized controlled trial investigated the clinical efficacy of WPS in 126 malnourished CAPD patients with serum albumin <40 g/L and body mass index (BMI) <24 kg/m. Seventy-four patients (n = 37 per group) completed the study. Significantly more IG patients (59.5%) achieved dietary protein intake (DPI) adequacy of 1.2 g/kg per ideal body weight (p < 0.001) compared to CG (16.2%) although difference in the adequacy of dietary energy intake between groups was non-significant (p > 0.05). A higher DPI paralleled significant increases in serum urea (mean Δ: IG = +2.39 ± 4.36 mmol/L, p = 0.002, d = 0.57 vs CG = -0.39 ± 4.59 mmol/L, p > 0.05, d = 0.07) and normalized protein catabolic rate, nPCR (mean Δ: IG = +0.11 ± 0.14 g/kg/day, p < 0.001, d = 0.63 vs CG = +0.001 ± 0.17 g/kg/day, p > 0.05, d = 0.09) for IG compared to CG patients. Although not significant, comparison for changes in post-dialysis weight (mean Δ: +0.64 ± 1.16 kg vs +0.02 ± 1.36 kg, p = 0.076, d = 0.58) and mid-arm circumference (mean Δ: +0.29 ± 0.93 cm vs -0.12 ± 0.71 cm, p = 0.079, d = 0.24) indicated trends favoring IG vs CG. Other parameters remained unaffected by treatment comparisons. CG patients had a significant decline in QOL physical component (mean Δ = -6.62 ± 16.63, p = 0.020, d = 0.47). Using changes in nPCR level as a marker of WPS intake within IG, 'positive responders' achieved significant improvement in weight, BMI, skinfold measures and serum urea (all p < 0.05), while such changes within 'negative responders' were non-significant (all p > 0.05).. A single macronutrient approach with WPS in malnourished CAPD patients was shown to achieve DPI adequacy and improvements in weight, BMI, skin fold measures, serum urea and nPCR level.

To explore the epidemiological and histopathological patterns of glomerular diseases in Sabah.. A state-wide cross-sectional study was conducted. There were 336 native renal biopsies in 296 eligible patients from 1st January 2013 to 30th June 2016. All patients aged ≥12 years with sufficient sampling (≥8 glomeruli) for histopathological assessment were included. Graft kidney biopsies, protocol-based biopsies and patients with uncertain demographics were excluded. Demographics of patients, clinical data, laboratory parameters prior to biopsy, and histology findings of renal biopsies were collected from local unit database and recorded into a standardised data collection form. Descriptive statistical analyses were employed and factors associated with Lupus nephritis (LN) were explored using logistic regression.. The mean age during biopsy was 34.53 years (Standard Deviation 0.759). Primary glomerulonephritis (PGN) accounted for 42.6% (126) of all native renal biopsies. The commonest cause of PGN was minimal change disease (38.9%, 49) followed by focal segmental glomerulosclerosis (33.3%, 42) and IgA nephropathy (14.3%, 18). LN is the leading cause for secondary glomerulonephritis (SGN) (87.2%, 136). Younger age (Odds Ratio, OR 0.978; 95% Confidence Interval, 95%CI 0.960, 0.996); female gender (OR 17.53; p<0.001); significant proteinuria (OR 132.0; p<0.001); creatinine level at biopsy (OR 11.26; p=0.004); positive antinuclear antibody (ANA) (OR 46.7; p<0.001); and ANA patterns (OR 8.038; p=0.018) were significant in predicting the odds of having LN.. This is the first epidemiology study of glomerular diseases in Sabah. The predominance of LN suggests lower threshold for renal biopsy in patients with suspected glomerular disorders. We have identified significant predictors for early detection and treatment of LN.

Feline morbillivirus (FeMV), a novel virus from the family of Paramyxoviridae, was first identified in stray cat populations. The objectives of the current study were to (i) determine the molecular prevalence of FeMV in Malaysia; (ii) identify risk factors associated with FeMV infection; and (iii) characterise any FeMV isolates by phylogenetic analyses. Molecular analysis utilising nested RT-PCR assay targeting the L gene of FeMV performed on either urine, blood and/or kidney samples collected from 208 cats in this study revealed 82 (39.4%) positive cats. FeMV-positive samples were obtained from 63/124 (50.8%) urine and 20/25 (80.0%) kidneys while all blood samples were negative for FeMV. In addition, from the 35 cats that had more than one type of samples collected (blood and urine; blood and kidney; blood, urine and kidney), only one cat had FeMV RNA in the urine and kidney samples. Risk factors such as gender, presence of kidney-associated symptoms and cat source were also investigated. Male cats had a higher risk (p = 0.031) of FeMV infection than females. In addition, no significant association (p = 0.083) was observed between the presence of kidney-associated symptoms with FeMV status. From the 82 positive samples, FeMV RNA was detected from 48/82 (58.5%) pet cats and 34/126 (27.0%) shelter cats (p < 0.0001). Partial L and N gene sequencing of the RT-PCR-positive samples showed 85-99% identity to the published FeMV sequences and it was significantly different from all other morbilliviruses. A phylogenetic analysis of the identified Malaysian FeMVs was performed with isolates from Japan, Thailand and China. Molecular characterisation revealed high relatedness of the Malaysian isolates with other Asian FeMVs, indicating that the virus had been circulating only within the region. Therefore, this study confirmed the existence of FeMV among domestic cats in Malaysia. The findings suggest further characterisation of the local isolates, including the whole genome sequencing and that studies at determining the direct consequences of FeMV infection in domestic cats are needed.

Calcium infusion is used after parathyroid surgery for renal hyperparathyroidism to treat postoperative hypocalcaemia. We compared a new infusion regimen to one commonly used in Malaysia based on 2003 K/DOQI guidelines.. Retrospective data on serum calcium and infusion rates was collected from 2011-2015. The relationship between peak calcium efflux (PER) and time was determined using a scatterplot and linear regression. A comparison between regimens was made based on treatment efficacy (hypocalcaemia duration, total infusion amount and time) and calcium excursions (outside target range, peak and trough calcium) using bar charts and an unpaired t-test.. Fifty-one and 34 patients on the original and new regimens respectively were included. Mean PER was lower (2.16 vs 2.56 mmol/h; P = 0.03) and occurred earlier (17.6 vs 23.2 h; P = 0.13) for the new regimen. Both scatterplot and regression showed a large correlation between PER and time (R-square 0.64, SE 1.53, P < 0.001). The new regimen had shorter period of hypocalcaemia (28.9 vs 66.4 h, P = 0.04), and required less calcium infusion (67.7 vs 127.2 mmol, P = 0.02) for a shorter duration (57.3 vs 102.9 h, P = 0.001). Calcium excursions, peak and trough calcium were not significantly different between regimens. Early postoperative high excursions occurred when the infusion was started in spite of elevated peri-operative calcium levels.. The new infusion regimen was superior to the original in that it required a shorter treatment period and resulted in less hypocalcaemia. We found that early aggressive calcium replacement is unnecessary and raises the risk of rebound hypercalcemia.

Tenofovir (TDF) has been associated with renal function deterioration, but local data regarding the incidence and risk factors for this adverse event were lacking.. To determine the incidence of nephrotoxicity in HIV-infected patients on tenofovir-based regimens and to evaluate risk factors involved in tenofovir-associated renal function decline.. This is a single-centre retrospective cohort study of 440 HIV-infected adults who were started on tenofovirbased antiretroviral regimens. Data were extracted from electronic medical and pharmacy records.. A decline in eGFR of 25% or more was seen in 67 patients (15.2%) with an estimated incidence rate of 12 per 100 person-years. Among all 440 subjects, 22 discontinued TDF-based therapy due to renal complication. From multivariate analysis, the odds of developing >25% decrease in eGFR with tenofovir-containing regimen was three times higher for patients with baseline moderate renal impairment (HR 3.19; 95% CI, 1.43-7.12; p=0.005) and 14 times higher for patients with baseline severe renal impairment (HR 14.2; 95% CI, 11.20-170.7; p=0.036) as compared to those without pre-existing renal insufficiency. Age above 50 years and CD4 cell count of less than 50 were significantly associated with >25% decrement in eGFR.. The incidence rate of tenofovir-related renal dysfunction was found to be 12 per 100 person-years. Preexisting renal impairment, age 50 and above, and CD4 cell count below 50 as were predictors for renal function decline. Given that the use of tenofovir is escalating in Malaysia, increased awareness about this adverse event is essential.

Established 20 years ago with a single dialysis center assisting only 20 patients with 6 hemodialysis machines, Medicare has grown leaps and bounds to assist thousands of poor patients to obtain a highly subsidized rate for quality treatment. Millions of ringgit raised via various fundraising projects and events have been well utilized to serve the growing number of kidney patients in Malaysia who simply cannot bear the exorbitant cost of treatment. Staying true to its mission, Medicare extends its assistance to needy kidney patients and their families, who indirectly have become part of the Medicare family.

Kidney biopsy is indicated to confirm the clinical diagnosis or to evaluate prognosis of a renal problem. It is a reliable and safe procedure, especially with real-time ultrasound guidance. This is a single-center, retrospective review of the biopsies performed in Hospital Tengku Ampuan Afzan, Pahang from 2000 to 2010. The demographic data, clinical parameters, and histological reports were extracted from clinic records and analyzed to determine the diagnostic adequacy of biopsy samples for both lupus and non-lupus patients. A total of 219 biopsies were performed throughout the period and only 74 were included in this review. Their mean age was 22.5 ± 10.5 years. 59.5% of the biopsies were performed on female patients. Malays comprised 79.7% (n = 59) of them, followed by Chinese (18.9%, n=14) and Indian (1.4%, n=1). About one-third of the biopsies(n = 25) were performed on patients with lupus nephritis and two-thirds (n = 49) on non-lupus nephritis patients. At the time of biopsy, their serum creatinine values were normal, serum albumin 28.4 ± 10 g/L and total cholesterol 8.9 ± 4.6 mmol/L (mean ± SD). The urine dipstick was 3+ for both proteinuria and hematuria and daily protein excretion was 3.6 ± 3.2 g. Sixty-seven specimens were considered adequate and only six (8%) were inadequate for histological interpretations. The mean number of glomeruli in the biopsy specimens was 16 ± 9.9 (range: 0-47 glomeruli). In non-lupus patients, focal segmental glomerulosclerosis was the commonest histological diagnosis (n = 15, 30.6%), followed by minimal change disease (n = 13, 26.5%) and mesangial proliferative glomerulonephritis (n = 7, 14.3%). Membranous nephropathy was diagnosed in four (8.2%) and membranoproliferative glomerulonephritis in two (4.1%) specimens. Both post-infectious glomerulonephritis and advanced glomerulosclerosis were found in one specimen each. Among the lupus nephritis patients (n = 25), 88% of them were females (P <0.05) and lupus nephritis WHO class IV was the commonest variant (n = 12, 48%) followed by WHO class III (n = 7, 28%). Membranous glomerulopathy or lupus nephritis WHO class V was found in three (12%), and two (8%) had lupus nephritis WHO class II. Serum albumin, urinalysis findings, and daily urinary protein excretion were comparable for both lupus and non-lupus patients. In conclusion, renal biopsy in our center is adequate and sufficient for histological interpretations and management of patients with renal problems.

Risk stratification in ST-elevation myocardial infarction (STEMI) is important, such that the most resource intensive strategy is used to achieve the greatest clinical benefit. This is essential in developing countries with wide variation in health care facilities, scarce resources and increasing burden of cardiovascular diseases. This study sought to validate the Thrombolysis In Myocardial Infarction (TIMI) risk score for STEMI in a multi-ethnic developing country.. Data from a national, prospective, observational registry of acute coronary syndromes was used. The TIMI risk score was evaluated in 4701 patients who presented with STEMI. Model discrimination and calibration was tested in the overall population and in subgroups of patients that were at higher risk of mortality; i.e., diabetics and those with renal impairment.. Compared to the TIMI population, this study population was younger, had more chronic conditions, more severe index events and received treatment later. The TIMI risk score was strongly associated with 30-day mortality. Discrimination was good for the overall study population (c statistic 0.785) and in the high risk subgroups; diabetics (c statistic 0.764) and renal impairment (c statistic 0.761). Calibration was good for the overall study population and diabetics, with χ2 goodness of fit test p value of 0.936 and 0.983 respectively, but poor for those with renal impairment, χ2 goodness of fit test p value of 0.006.. The TIMI risk score is valid and can be used for risk stratification of STEMI patients for better targeted treatment.

The prevalence of hypertension in Malaysia is alarmingly high. The National Survey in 2006 showed 43% of people aged ≥30 had hypertension and among treated patients, only 26% reached the target blood pressure (BP) of <140/90 mmHg. We evaluated BP control in tertiary institutions in Malaysia and the difference in hypertension control between genders and within specific cardiovascular risk factor groups. This cross-sectional study aimed at determining BP control among hypertensive patients attending three specialist institutions in Malaysia, located in Kuala Lumpur, Kuantan and Kota Bharu. A total of 950 patients with known hypertension for at least 6 months were recruited between January 2007 and July 2008. There were more males (n=548, 57.7%) with a mean age of 60.3±10.5 (±s.d.) years. The mean systolic BP (SBP) and diastolic BP were 138.8±20.3 mmHg and 79.6±11.3 mmHg, respectively. In total, 48.5% of all the patients had good BP control (<140/90 mmHg). Males had better SBP control compared with female (SBP: 135.9±18.7 vs. 142.8±21.7 mmHg, P<0.001). Overall, 54.6% of the patients had ischemic heart disease (IHD), 24.2% had undergone coronary revascularization, 50.1% were diabetic, 68.6% hyperlipidemic, 17.3% smokers and 27.5% had renal impairment. Males and small numbers of antihypertensives used were independently associated with better treatment outcome. In summary, our data reveal a poorer BP control, secondary to higher SBP levels in women. Moreover, the gender difference is more pronounced in patients with concomitant diabetes mellitus, renal impairment and IHD.

Murraya koenigii (Linn.) Spreng (curry leaf) is widely used as a nephroprotective agent in kidney's infirmities among diabetics by the traditional practitioners in Malaysia. However, the latter role of curry leaf has been grossly under reported and is yet to receive proper scientific evaluation.. The present study was designed to investigate the beneficial effect of the leaves of Murraya koenigii (Linn.) on diabetes-induced renal damage in vivo with regard to prove its efficacy by local traditional practitioners in the treatment of kidney frailties in diabetics.. Aqueous (AQ) extract of the leaves of Murraya koenigii (Linn.) was administered to both normal and streptozotocin (STZ) induced diabetic male rats (Sprague-Dawley strain). Animals were divided into six groups (n=6) and treated with variable dose levels of AQ extract (200 and 400mg/kg body weight/day) for 30 days. At the end of 30 days, animals were sacrificed, blood was collected, processed and stored at -70°C for the zestimation of serum urea and creatinine, changes in plasma antioxidant capacity by FRAP assay, and glutathione peroxidase levels, in the normal and STZ-induced diabetic rats. Histological changes of the kidneys of these animals were also evaluated by light microscopy to determine the beneficial effect of the leaves.. Daily oral administration of variable dose levels of the AQ extract for 30 days, produced significant dose dependant decrease in serum urea and creatinine levels (p<0.001), and marked increase in the levels of plasma antioxidant capacity (p<0.01) in diabetic treated rats, compared to the control (non-diabetic) subjects. However, the normal treated rats showed minimal variation in these parameters in comparison to normal controls. Histological studies of the kidneys of these animals showed comparable tissue regeneration by the AQ extract.. The results of our study scientifically support the traditional belief for using the leaves of Murraya koenigii (Linn.) as adjuvant, in the treatment of pain disorders related to renal impairments among diabetics.

There is substantial heterogeneity in literature regarding the epidemiology for chronic kidney disease (CKD) in different Asian populations. We aimed to assess the prevalence and risk factors of CKD in a multi-ethnic Asian population in Singapore.. We examined 4499 participants of Chinese, Malay and Indian ethnicity, aged 24-95 years, who participated in the Singapore Prospective Study Program. CKD was defined as an estimated glomerular filtration rate <60 ml/min/1.73 m(2) or the presence of micro/macroalbuminuria.. The age, sex-standardized prevalence of CKD was 12.8% (11.4%, 18.6% and 17.6% in Chinese, Malays and Indians). Older age and the presence of diabetes, hypertension and dyslipidaemia were significantly associated with CKD in all ethnic groups. Clinical, metabolic, socioeconomic and behavioral factors accounted for 68% and 78% of excess risk of CKD in Malays and in Indians, respectively. Diabetes (45%) and dyslipidaemia (16%) among Malays and hypertension among Indians (23%) had greater population-attributable risk of CKD.. The prevalence of CKD is high in all three major Asian ethnic groups, in particular Malays and Indians, but risk factors are similar to those reported from previous studies in Western populations. The association of modifiable risk factors with CKD emphasizes the need to screen and treat high-risk populations for early detection and prevention of CKD.

Western-style medicine was introduced to Malaya by the Portuguese, Dutch and British between the 1500s and 1800s. Although the earliest pathology laboratories were developed within hospitals towards the end of the 19th Century, histopathology emerged much later than the biochemistry and bacteriology services. The University Departments of Pathology were the pioneers of the renal histopathology diagnostic services. The Department of Pathology, University of Malaya (UM) received its first renal biopsy on 19 May 1968. Hospital Universiti Kebangsaan Malaysia (HUKM) and Hospital Universiti Sains Malaysia (HUSM) started their services in 1979 and 1987 respectively. It is notable that the early services in these University centres caterred for both the university hospitals and the Ministry of Health (MOH) until the mid-1990s when MOH began to develop its own services, pivoted on renal pathologists trained through Fellowship programmes. Currently, key centres in the MOH are Kuala Lumpur Hospital, Sultanah Aminah Hospital Johor Bahru and Malacca Hospital. With the inclusion of renal biopsy interpretation in the Master of Pathology programmes, basic renal histopathology services became widely available throughout the country from 2000. This subsequently filtered out to the private sector as more histopathologists embraced private practice. There is now active continuing professional development in renal histopathology through clinicopathological dicussions, seminars and workshops. Renal research on amyloid nephropathy, minimal change disease, IgA nephropathy, fibrillary glomerulonephritis, lupus nephritis and microwave technology have provided an insight into the patterns of renal pathology and changing criteria for biopsy. More recently, there has been increasing involvement of renal teams in clinical trials, particularly for lupus nephritis and renal transplant modulation.

The Malaysian National Renal Registry was set up in 1992 to collect data for patients on renal replacement therapy (RRT). We present here the report of the Malaysian dialysis registry. The objectives of this papar are: (1) To examine the overall provision of dialysis treatment in Malaysia and its trend from 1980 to 2006. (2) To assess the treatment rate according to the states in the country. (3) To describe the method, location and funding of dialysis. (4) To characterise the patients accepted for dialysis treatment. (5) To analyze the outcomes of the dialysis treatment. Data on patients receiving dialysis treatment were collected at initiation of dialysis, at the time of any significant outcome, as well as yearly. The number of dialysis patients increased from 59 in 1980 to almost 15,000 in 2006. The dialysis acceptance rate increased from 3 per million population in 1980 to 116 per million population in 2006, and the prevalence rate from 4 to 550 per million population over the same period. The economically advantaged states of Malaysia had much higher dialysis treatment rates compared to the less economically advanced states. Eighty to 90% of new dialysis patients were accepted into centre haemodialysis (HD), and the rest into the chronic ambulatory peritoneal dialysis (CAPD) programme. The government provided about half of the funding for dialysis treatment. Patients older than 55 years accounted for the largest proportion of new patients on dialysis since the 1990s. Diabetes mellitus has been the main cause of ESRD and accounted for more than 50% of new ESRD since 2002. Annual death rate averaged about 10% on HD and 15% on CAPD. The unadjusted 5-year patient survival on both HD and CAPD was about 80%. Fifty percent of dialysis patients reported very good median QoL index score. About 70% of dialysis patients were about to work full or part time. There has been a very rapid growth of dialysis provision in Malaysia particularly in the older age groups. ESRD caused by diabetes mellitus, despite being a preventable and treatable cause of ESRD--has increased and accounted for more than 50% of incident dialysis patients. Death and survival rates on dialysis are comparable to those from other countries.

The factors associated with proteinuria were examined in a large multiracial Asian population participating in a screening program aimed at the early detection of renal disease. Of 213,873 adults who participated, 189,117 with complete data were included. Malay race, increasing age, both extremes of body mass index (BMI), self-reported family history of kidney disease (FKD), and higher systolic and diastolic BP measurements (even at levels classified as being within the normal range) were independently associated with dipstick-positive proteinuria. The odds ratios (OR) for proteinuria increased progressively with age. There was a J-shaped relationship between BMI and proteinuria (OR of 1.3, 1.00, 1.3, 1.6, and 2.5 for BMI of < or =18.00, 23.00 to 24.99, 25.00 to 27.49, 27.50 to 29.99, and > or =30.00 kg/m(2), respectively, compared with BMI of 18.01 to 22.99 kg/m(2)). OR for proteinuria according to systolic and diastolic BP were significantly increased beginning at levels of 110 and 90 mmHg, respectively. In addition, the Malay race was associated with a significantly higher OR for proteinuria, compared with the Chinese race (OR of 1.3). Finally, FKD was significantly associated with proteinuria (OR of 1.7), whereas a family history of diabetes mellitus and a family history of hypertension were not. When family histories were analyzed by clustering, isolated FKD remained a significant determinant of proteinuria and the magnitude of the effect was not significantly different from that observed in the presence of a coexisting family history of diabetes mellitus or hypertension. This is the first study to evaluate factors associated with proteinuria in an Asian population. The epidemiologic study of renal disease in this population suggests that risk factors for renal disease might differ significantly among racial groups.

Consecutive renal biopsies received from 1994 to 2000 in Johor Bahru were reviewed. There were 441 cases, of which 407 were adequate biopsies (92.3%). Lupus nephritis formed the largest diagnostic entity (126 cases, 31.0%). This reflected the high prevalence of systemic lupus erythematosus (SLE) patients in Malaysia. The most common histological pattern of lupus nephritis was diffuse proliferative glomerulonephritis: WHO Class IV (96 cases, 76.2%). Other diagnostic entities were minimal change disease (28.5%), proliferative glomerulonephritis (10.6%), IgA nephropathy (9.8%), focal glomerulosclerosis (4.9%), membranous glomerulonephritis (4.4%), transplant rejection (3.9%), end stage nephropathy (3.4%) and others (3.4%). The morphological pattern of renal biopsies in Johor was similar to that reported in the University Hospital Kuala Lumpur.

A retrospective analysis of the case records of 494 systemic lupus erythematosus (SLE) patients under follow-up at University Hospital, Kuala Lumpur during 1976-1990 was performed. Overall mortality was 20.2% (100 patients). The causes of death were infection (30%), renal (15%), respiratory (14%), neurological (5%), cardiovascular (7%), other causes (2%) and unknown (27%). Active SLE was a contributing factor in 19% of the deaths. The patients who died had significantly more renal disease, neurological disease, serositis or thrombocytopenia by the end of the first year of disease compared to the survivors. As in other series, infection and active SLE remain important causes of death.

To determine the effects of ethnicity on disease manifestations in Oriental patients with systemic lupus erythematosus (SLE) and to describe the risk of developing renal or central nervous system (CNS) involvement with time.. A retrospective study of 472 patients with SLE seen at the only Rheumatology Unit in Singapore. The effect of ethnicity on selected disease manifestations at diagnosis was assessed after adjusting for demographic variables using multiple logistic regression. The probability of developing selected disease manifestations with time was determined using the Kaplan-Meier product limit method.. At diagnosis, Malays had a higher risk of renal or CNS involvement than Chinese (OR 2.26, 95% CI 1.21 to 4.21, and OR 3.07, 95% CI 1.01 to 9.34, respectively), and Indians a lower risk of malar rash and a higher risk of oral ulcers than Chinese (OR 0.30, 95% CI 0.13 to 0.68, and OR 2.90, 95% CI 1.45 to 7.34, respectively). The prevalence of renal or CNS involvement in the entire cohort increased with time, reaching 75.6% (95% CI 66.1% to 85.0%) and 16.7% (95% CI 11.7% to 21.6%), respectively, after 18 years of disease.. Ethnicity influenced disease manifestations at diagnosis in this cohort of Oriental patients with SLE. Renal or CNS involvement developed in previously unaffected patients up to 18 years after diagnosis, highlighting the need for continued vigilance in patients with lupus.

Congo red screening of routine biopsies at the University Hospital Kuala Lumpur revealed the following categories of amyloidosis: systemic AL (5.9%); systemic AA (3.2%); isolated atrial (14%); primary localized cutaneous (7.5%); other primary localized deposits (3.2%); localized intratumour (58%); and dystrophic (8.6%). Unlike in the West, AA amyloidosis in this population was usually secondary to leprosy or tuberculosis. Liver involvement in AL amyloidosis was shown to exhibit a sinusoidal pattern and differed from the vascular pattern of AA amyloidosis. Within the category of AA amyloidosis, there were two patterns of renal involvement--glomerular and vascular, with the glomerular pattern carrying a more ominous clinical picture. Notable among the localized amyloidoses were isolated atrial amyloidosis complicating chronic rheumatic heart disease, intratumour amyloidosis within nasopharyngeal carcinomas and dystrophic amyloidosis which occurred in fibrotic tissues.

An analysis of 1000 consecutive, adequate renal biopsies from patients of the University Hospital Kuala Lumpur between 1982 and 1991 revealed: minimal change nephritis (20.7%), focal glomerulosclerosis (2.9%), proliferative glomerulonephritides (16.0%), membranous glomerulonephritis (5.5%), IgA nephropathy (18.5%), lupus nephritis (24.9%), end stage nephropathy (3.1%) and others (8.4%). Compared with the previous decade, IgA nephropathy has emerged as a common entity. Lupus nephritis forms the largest diagnostic entity and is probably related to the selected referral of SLE patients to this hospital.

Seven cases of analgesic nephropathy due to excessive ingestion of paracetamol are reported. None of these patients had been taking any other analgesic. All had radiological features of papillary necrosis. With the increasing use of paracetamol as a mild analgesic it is necessary to be aware of the possibility that paracetamol may induce analgesic nephropathy.

Adequately biopsied renal tissue received in the Department of Pathology, University Hospital, Kuala Lumpur from 1,000 consecutive Malaysian patients during an eleven year period between 1970 and 1981 was reviewed. The youngest patient was 6 days old and the oldest 80 years. Both sexes were equally represented. The majority of the patients were Chinese (71%) with Malays and Indians comprising most of the remainder. Over half the patients (50.4%) presented with the nephrotic syndrome. Other modes of presentation included systemic lupus erythematosus, proteinuria and haematuria separately or in combination and hypertension. Minimal change (25.7%) and proliferative glomerulonephritis (24.8%) were present in about equal numbers and together accounted for over half of the cases (50.5%). Lupus nephritis was the third most common diagnosis (18.4%). In addition, there were patients with focal glomerulonephritis (5.4%), membranous glomerulonephritis (5.5%), Berger's disease (5.8%), amyloidosis (0.6%) and end stage renal disease (4.0%).
