    We examined the prevalence of diabetes among inpatients in our hospital, the relationship of the diagnoses on admission to diabetes, and the frequency of testing for HbA1c as a marker of long-term glycaemic control, proteinuria, and hypercholesterolaemia. In addition, patients with raised laboratory plasma glucose without a know history of diabetes mellitus, were studied to see if these had been further evaluation. The overall prevalence of diabetes in our hospital was 25.% with the highest prevalence found (37.8%) on medical wards. 10.5% of admissions were due directly to diabetes and a further 58.9% of patients were admitted with illness which were significant related to diabetes. Overall testing rates for HbA31c, proteinuria, and hypercholesterolaemia were less than ideal (51.6, 73.4 and 45.% respectively). Less than 50% of patients without previously diagnosed diabetes but with high plasma glucose values had further evaluation for diabetes. In conclusion, this study has detected a high overall prevalence of diabetes among inpatients in an urban Malaysian hospital. Rates of testing for HbA51c, proteinuria, and hypercholesterolaemia, are disappointingly low, as is further evaluation of patients without known diabetes, but with elevated glucose values. More effective measures to improve the delivery of inpatient diabetes care are needed.

    This paper investigates the dielectric properties of urine in normal subjects and subjects with chronic kidney disease (CKD) at microwave frequency of between 0.2 GHz and 50 GHz. The measurements were conducted using an open-ended coaxial probe at room temperature (25°C), at 30°C and at human body temperature (37°C). There were statistically significant differences in the dielectric properties of the CKD subjects compared to those of the normal subjects. Statistically significant differences in dielectric properties were observed across the temperatures for normal subjects and CKD subjects. Pearson correlation test showed the significant correlation between proteinuria and dielectric properties. The experimental data closely matched the single-pole Debye model. The relaxation dispersion and relaxation time increased with the proteinuria level, while decreasing with the temperature. As for static conductivity, it increased with proteinuria level and temperature.

    IMPORTANCE: The effect of glucocorticoids on major kidney outcomes and adverse events in IgA nephropathy has been uncertain.

    OBJECTIVE: To evaluate the efficacy and adverse effects of methylprednisolone in patients with IgA nephropathy at high risk of kidney function decline.

    DESIGN, SETTING, AND PARTICIPANTS: An international, multicenter, double-blind, randomized clinical trial that enrolled 503 participants with IgA nephropathy, proteinuria greater than or equal to 1 g per day, and estimated glomerular filtration rate (eGFR) of 20 to 120 mL/min/1.73 m2 after at least 3 months of optimized background care from 67 centers in Australia, Canada, China, India, and Malaysia between May 2012 and November 2019, with follow-up until June 2021.

    INTERVENTIONS: Participants were randomized in a 1:1 ratio to receive oral methylprednisolone (initially 0.6-0.8 mg/kg/d, maximum 48 mg/d, weaning by 8 mg/d/mo; n = 136) or placebo (n = 126). After 262 participants were randomized, an excess of serious infections was identified, leading to dose reduction (0.4 mg/kg/d, maximum 32 mg/d, weaning by 4 mg/d/mo) and addition of antibiotic prophylaxis for pneumocystis pneumonia for subsequent participants (121 in the oral methylprednisolone group and 120 in the placebo group).

    MAIN OUTCOMES AND MEASURES: The primary end point was a composite of 40% decline in eGFR, kidney failure (dialysis, transplant), or death due to kidney disease. There were 11 secondary outcomes, including kidney failure.

    RESULTS: Among 503 randomized patients (mean age, 38 years; 198 [39%] women; mean eGFR, 61.5 mL/min/1.73 m2; mean proteinuria, 2.46 g/d), 493 (98%) completed the trial. Over a mean of 4.2 years of follow-up, the primary outcome occurred in 74 participants (28.8%) in the methylprednisolone group compared with 106 (43.1%) in the placebo group (hazard ratio [HR], 0.53 [95% CI, 0.39-0.72]; P

    Screening for proteinuria and hematuria is important in the prevention of chronic renal disease. In Malaysia to date no such attempt has been made to establish the prevalence of proteinuria and hematuria. A total of 45,149 primary school children from three districts in Kelantan were screened for proteinuria and hematuria. They were 23,289 boys and 21,860 girls. The prevalence of abnormal urinary sediments after third screening was 0.17% ie 0.07% were in boys and 0.10% were in girls. The commonest abnormality was proteinuria (0.12%), followed by hematuria (0.03%) and combination of proteinuria and hematuria (0.02%). Hematuria was more commonly seen in girls compared to boys while proteinuria was seen in almost equal proportion in boys and girls. Despite screening large number of children the prevalence of asymptomatic proteinuria and hematuria was far lower than in an earlier reported study. Furthermore the majority had mild abnormalities.

    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.

    Diabetic nephropathy is now the number one cause of end stage renal failure in Malaysia. This places a huge burden on patients and the health care system especially in developing countries with limited health care resources, such as in Sarawak in East Malaysia. This study describes the prevalence of proteinuria/microalbuminuria in diabetic patients treated in Klinik Kesihatan Tanah Puteh. Early detection of proteinuria/microalbuminuria allows remedial measures to be taken to retard the progression of nephropathy. Forty-eight percent of the cases had proteinuria and microalbuminuria was found in 16%. Seventy-eight percent of cases with proteinuria were on treatment with angiotensin-converting-enzyme inhibitors or angiotensin-receptor blockers. Seventy-five percent of patients had hypertension but only 6% achieved the targeted BP of < 130/80 mmHg.

    BACKGROUND: Patients treated for human immunodeficiency virus (HIV) infection are prone to developing chronic kidney disease (CKD). Current methods used in assessing kidney function suffer inaccuracy in HIV-infected patients. This study aims to identify biomarkers that could complement existing methods of kidney assessment among HIV-infected subjects.

    METHODS: Plasma protein profiling was performed for HIV patients with CKD presented with negative/trace proteinuria (non-proteinuric) (n = 8) and their matched non-CKD controls, using two-dimensional gel electrophoresis (2DE); selected protein candidates were identified using mass spectrometry. Subsequently, altered plasma abundance of protein candidates were verified using Western blotting in HIV-infected subjects with non-proteinuric CKD (n = 8), proteinuric CKD (n = 5), and their matched non-CKD controls, as well as in HIV-uninfected subjects with impaired kidney function (n = 3) and their matched controls.

    RESULTS: Analysis of 2DE found significantly altered abundance of five protein candidates between HIV-infected patients with non-proteinuric CKD and without CKD: alpha-1-microglobulin (A1M), serum albumin (ALB), zinc-alpha-2-glycoprotein (AZGP1), haptoglobin (HP), and retinol binding protein (RBP4). Western blotting showed an increased abundance of A1M and HP in HIV-infected patients with non-proteinuric CKD compared to their non-CKD controls, whereas A1M, AZGP1, and RBP4 were significantly increased in HIV-infected patients with proteinuric CKD compared to their non-CKD controls. Such pattern was not found in HIV-uninfected subjects with impaired kidney function.

    CONCLUSION: The data suggests four proteins that may be used as biomarkers of CKD in HIV-infected patients. Further validation in a larger cohort of HIV-infected patients is necessary for assessing the clinical use of these proposed biomarkers for CKD.

    PURPOSE: Macular edema, serous retinal detachment, and retinal pigment epithelial detachment have been reported in patients with nephrotic syndrome. However, there is limited data about macular thickness in children with nephrotic syndrome. The aim of this study was to compare the mean macular thickness in children with nephrotic syndrome and in a control group and to correlate it with visual acuity and level of proteinuria.

    METHODS: The comparative cross-sectional study included 66 children aged 6 to 17 years with nephrotic syndrome and healthy control seen in two tertiary centers in Malaysia. We recorded demographic data, as well as visual acuity, level of proteinuria, and the mean macular thicknesses in both groups. The mean macular thickness was measured using Stratus optical coherence tomography according to nine areas of the Early Treatment Diabetic Retinopathy Study map.

    RESULTS: The mean foveal thickness was 238.15 ± 22.98 µm for children with nephrotic syndrome and 237.01 ± 22.60 µm for the control group. There was no significant difference in the mean macular thickness between the groups (p = 0.843). A significant correlation with visual acuity was observed in the superior outer macula (r = -0.41, p = 0.019), the nasal outer macula (r = -0.41, p = 0.019), and the inferior outer macula (r = -0.40, p = 0.021). There was no significant correlation between the mean macular thickness and level of proteinuria (p = 0.338), although those with higher levels of proteinuria demonstrated a trend towards increased macular thickness.

    CONCLUSIONS: The mean macular thickness in children with nephrotic syndrome was similar to that of healthy children. A significant correlation between the mean thickness of the outer macular layer and the presenting visual acuity was observed. There was no correlation between the mean macular thickness and the level of proteinuria.

    Microalbuminuria is the earliest indicator of diabetic kidney disease and generalised vascular endothelial dysfunction. The Microalbuminuria Prevalence (MAP) Study was carried out to assess the prevalence of macroalbuminuria, microalbuminuria and normoalbuminuria in Asian hypertensive patients with type 2 diabetes on usual care. This paper presents a subanalysis of data from patients in Malaysia. In 733 analysed patients, the prevalence of macroalbuminuria and microalbuminuria was 15.7% and 39.7%, respectively. The high prevalence of diabetic nephropathy in these high-risk patients is a cause for concern, and the Malaysian Health Care system should be prepared for a pandemic of end-stage renal disease due to diabetic nephropathy.

    A survey was done to determine the prevalence of diabetes mellitus, hypertension and renal disease, as well as extent of diabetic control, amongst the workers of Malaysian Railways. The prevalence of diabetes was high at 6.6%, with 3.8% of these being insulin dependent diabetes. The highest prevalence was in Indians (16.0%) followed by Chinese (4.9%) and Malays (3.0%). Using HbA1 measurements, diabetic control was poor in 70.6% of the diabetics. Hypertension was found in 37% and proteinuria in 35%. Renal impairment was present in 30% of the diabetics. This survey shows that diabetes, hypertension and renal disease are high amongst the railway workers in Malaysia.

    Aim: Treatment of chronic kidney disease (CKD) poses a huge burden to the healthcare system. To address the problem, the National Kidney Foundation of Malaysia embarked on a programme to screen for proteinuria and educate the public on CKD.

    Methods: The public was invited for health screening and the data collected over a 21 month period was analyzed.

    Results: In total, 40400 adults from all the states in Malaysia were screened. The screening population had a mean age of 41 years, 30.1% had hypertension and 10.6% had diabetes. Proteinuria was detected in 1.4% and haematuria in 8.9% of the participants. Factors associated with the highest risk for proteinuria were the presence of diabetes (adjusted odds ratio (OR) 2.63 (95% confidence interval (CI) 2.16-3.21)), hypertension (OR 2.49 (95% CI 2.03-3.07)) and cardiac disease (OR 2.05 (95% CI 1.50-2.81)). Other risk factors identified were lower educational level, family history of kidney disease, hypercholesterolaemia, obesity and lack of regular exercise. Chinese had the lowest risk for proteinuria among the races (OR 0.71 (95% CI 0.57-0.87) compared with Malays). The combination of high blood glucose and high blood pressure (BP) substantially increased the risk for proteinuria (OR 38.1 for glucose ≥ 10 mmol/L and systolic BP ≥ 180 mm Hg and OR 47.9 for glucose ≥ 10 mmol/L and diastolic BP ≥ 110 mm Hg).

    Conclusion: The prevalence of proteinuria in Malaysia is similar to other countries. The major risk factors for proteinuria were diabetes, hypertension and cardiac disease. The presence of both high blood pressure and high blood glucose exert a synergistic effect in substantially increasing the risk for proteinuria.

    Cough associated with angiotensin converting-enzyme (ACE) inhibitor therapy has been reported in Western communities, where its incidence is disputed. We, therefore, reviewed our patients who were treated with captopril primarily for congestive cardiac failure. 19 of 61 patients (31.1%) receiving an ACE inhibitor had volunteered cough as an important adverse effect, compared with only one of 59 patients who recieved other treatment. In 3 patients, the cough was intolerably severe to require discontinuation of treatment. Another 7 patients were withdrawn from ACE inhibitor treatment because of other adverse effects including deteriorating renal function, insomnia, dizzy spells, ageusia and proteinuria, and skin rash. We suggest that although ACE inhibitors are very beneficial in improving the clinical status of congestive heart failure, intolerable adverse effects are not uncommon and might mandate withdrawal in a sizeable minority (16.4%).

    This study investigates the effect of ACE2 activation on leptin-induced changes in systolic blood pressure (SBP), proteinuria, endothelial activation and ACE2 expression during pregnancy in Sprague-Dawley rats. Pregnant rats were given subcutaneous injection of either saline, or leptin, or leptin plus xanthenone (ACE2 activator), or xanthenone (XTN) alone. SBP, serum ACE, ACE2, endothelin-1, E-selectin and ICAM-1 levels were estimated; also their gene expressions were determined in the kidney and aorta respectively. Compared to control, SBP was higher in the leptin-only treated group (P<0.001) and lower in rats treated with xanthenone alone (P<0.01). Proteinuria, markers of endothelial activation were significantly higher than controls in leptin-only treated rats (P<0.05). ACE2 activity and expression were lower in leptin-only treated rats when compared to controls (P<0.05). It seems, leptin administration during pregnancy significantly increases SBP, proteinuria, endothelial activation, but decreases ACE2 level and expression. These effects are prevented by concurrent administration of xanthenone.
