Fulltext Effect of socioeconomic status and healthcare provider on post-transplantation care in Malaysia: A multi-centre survey of kidney transplant recipients

Gan Kim Soon P, Rampal S, Lim SK, Su TT

PLoS One, 2023;18(4):e0284607.
PMID: 37075033 DOI: 10.1371/journal.pone.0284607

INTRODUCTION: As the rate of end-stage kidney disease rises, there is an urgent need to consider the catastrophic health expenditure of post-transplantation care. Even a small amount of out-of-pocket payment for healthcare can negatively affect households' financial security. This study aims to determine the association between socioeconomic status and the prevalence of catastrophic health expenditure in post-transplantation care.
METHOD: A multi-centre cross-sectional survey was conducted in person among 409 kidney transplant recipients in six public hospitals in the Klang Valley, Malaysia. Catastrophic health expenditure is considered at 10% out-of-pocket payment from household income used for healthcare expenditure. The association of socioeconomic status with catastrophic health expenditure is determined via multiple logistic regression analysis.
RESULTS: 93 kidney transplant recipients (23.6%) incurred catastrophic health expenditures. Kidney transplant recipients in the Middle 40% (RM 4360 to RM 9619 or USD 1085.39 -USD 2394.57) and Bottom 40% (RM 9619 or > USD 2394.57) income group. Kidney transplant recipients in the Bottom 40% and Middle 40% income groups were more susceptible to catastrophic health expenditure at 2.8 times and 3.1 times compared to higher-income groups, even under the care of the Ministry of Health.
CONCLUSION: Universal health coverage in Malaysia cannot address the burden of out-of-pocket healthcare expenditure on low-income Kidney transplant recipients for long-term post-transplantation care. Policymakers must reexamine the healthcare system to protect vulnerable households from catastrophic health expenditures.

Fulltext Prevalence and Pattern of Glomerulonephritis: An Experience of Two Tertiary Centers in Malaysia

Maifata S, Hod R, Ghani FA, Zakaria F

Saudi J Kidney Dis Transpl, 2023 Mar 01;34(2):167-177.
PMID: 38146727 DOI: 10.4103/1319-2442.391896

The prevalence of glomerulonephritis (GN), especially membranous GN (MGN), changes from time to time. This change may be due to genetic predisposition, environmental factors race, age, and indications for a renal biopsy. This study was conducted to evaluate the distribution and changing patterns of GN by further assessing the prevalence of MGN. A 1000, 123 biopsies were performed from January 2012 to October 2019 in Hospital Serdang and Hospital Kuala Lumpur. Electron microscopy, immunohistochemistry, and clinical presentations were used to differentiate primary and secondary MGN, from which 611 and 457 primary and secondary subjects were diagnosed with primary and secondary GN, respectively. Primary MGN accounts for 13% of all the primary GN, while lupus nephritis (LN) accounts for 44.2% of all secondary GN followed by diabetes mellitus (25.6%). The proportions of primary and secondary MGN were 64.8% and 35.2%, respectively, with a male-to-female ratio of 1:1.1 in favor of females. The renal biopsy obtained from the registry of two prominent hospitals in Malaysia provided valuable prevalence and demonstrated changes in the prevalence of GN in Malaysia. Notwithstanding, immunoglobulin A nephropathy and LN remain the most common causes of primary and secondary GN in Malaysia.

The countries of Asia are home to multiple ethnicities. There are ethnic differences in diet, culture, and attitudes towards health screening, access to care, and treatment of chronic diseases. Chronic kidney disease (CKD) and end-stage kidney disease (ESKD) have rising incidence and prevalence due to increased affliction with non-communicable diseases of diabetes and hypertension. To prevent the expensive complications of ESKD, one of the most important risk factors to control is hypertension in patients with CKD. We performed a narrative review on the prevalence of CKD in patients with hypertension, the prevalence and control of hypertension in patients with CKD, and the dietary sodium intake in CKD populations.

Fulltext Bilateral Emphysematous Pyelonephritis with Hepatic Portal Venous Gas: Case Report

Cheng ML, Nording H, Lim CH

Malays J Med Sci, 2015 May-Jun;22(3):71-4.
PMID: 26715900 MyJurnal

Emphysematous pyelonephritis is a rare life-threatening condition caused by a severe acute necrotising infection of the renal parenchyma and its perinephric tissues, and it is commonly seen in diabetic patients. There is a rare association between emphysematous pyelonephritis and hepatic portal venous gas. Hepatic portal venous gas is an uncommon radiological finding, which implies a significant underlying abdominal disease. The management of emphysematous pyelonephritis has evolved from prompt nephrectomy to medical therapy. In the present report, we present a case of a diabetic woman diagnosed with bilateral emphysematous pyelonephritis with hepatic portal venous gas that was successfully managed medically despite the presence of poor prognostic factors, such as acute renal failure and thrombocytopenia.

Fulltext Zinc Supplementation and Ischemia Pre-conditioning in Renal Ischemia/Reperfusion Injury

Mazaheri B, Emami F, Moslemi F, Talebi A, Nematbakhsh M

Malays J Med Sci, 2019 Jul;26(4):39-46.
PMID: 31496892 DOI: 10.21315/mjms2019.26.4.5

Backgrounds: Renal ischemia/reperfusion (RIR) is a major cause of kidney dysfunction in clinic. The main objective of this study was to investigate the effect of pre-conditioning ischemia (IPC) and zinc (Zn) supplementation on renal RIR injury.
Methods: A total of 63 unilateral nephrectomised male and female Wistar rats were divided into five groups. Group 1 (ShOPR): Rats as sham-operated group were subjected to surgical procedure without RIR. Group 2 (Isch): Rats underwent RIR (left kidney ischemia for 30 min followed by 48 h reperfusion). Group 3 (Zn+Isch): Rats were treated as group 2 but they received Zn sulphate (30 mg/kg) 1 h before induction of RIR. Group 4 (IPC+Isch): Rats were treated as group 2 but they underwent 1 min of ischemia followed by 3 min reperfusion as IPC, which was repeated for three times before induction of RIR. Group 5 (Zn+IPC+Isch): Rats were subjected to receive both Zn sulphate and IPC before induction of RIR. Urine samples were collected in the last 6 h of reperfusion, and finally biochemical and histological measurements were performed.
Results: The serum level of creatinine (Cr), normalised kidney weight (KW) and kidney tissue damage score (KTDS) increased by RIR alone significantly (P < 0.05). These parameters were attenuated statistically by Zn supplementation (P < 0.05). However, IPC alone or co-treatment of Zn and IPC did not improve the biochemical and histological markers altered by RIR injury.
Conclusion: Zn supplementation had a protective role against RIR while such protective effect was not observed by IPC alone or by co-treatment of Zn and IPC.

Somchit MN, Sanat F, Hui GE, Wahab SI, Ahmad Z

Adv Pharm Bull, 2014 Dec;4(4):401-4.
PMID: 25436198 DOI: 10.5681/apb.2014.059

PURPOSE: Nonsteroidal anti-inflammatory drugs (NSAIDs) are used for the treatment of many joint disorders, inflammation and to control pain. Numerous reports have indicated that NSAIDs are capable of producing nephrotoxicity in human. Therefore, the objective of this study was to evaluate mefenamic acid, a NSAID nephrotoxicity in an animal model.
METHODS: Mice were dosed intraperitoneally with mefenamic acid either as a single dose (100 or 200 mg/kg in 10% Dimethyl sulfoxide/Palm oil) or as single daily doses for 14 days (50 or 100 mg/kg in 10% Dimethyl sulfoxide/Palm oil per day). Venous blood samples from mice during the dosing period were taken prior to and 14 days post-dosing from cardiac puncture into heparinized vials. Plasma blood urea nitrogen (BUN) and creatinine activities were measured.
RESULTS: Single dose of mefenamic acid induced mild alteration of kidney histology mainly mild glomerular necrosis and tubular atrophy. Interestingly, chronic doses induced a dose dependent glomerular necrosis, massive degeneration, inflammation and tubular atrophy. Plasma blood urea nitrogen was statistically elevated in mice treated with mefenamic acid for 14 days similar to plasma creatinine.
CONCLUSION: RESULTS from this study suggest that mefenamic acid as with other NSAIDs capable of producing nephrotoxicity. Therefore, the study of the exact mechanism of mefenamic acid induced severe nephrotoxicity can be done in this animal model.

Fulltext Durian induced hyperkalaemia

Leo CL, Leong WS, Tieh CS, Liew CK

Med J Malaysia, 2011 Mar;66(1):66-7.
PMID: 23765149 MyJurnal

Hyperkalaemia is a life threatening acute medical emergency. Patients with end stage renal failure are more prone to get hyperkalaemia as potassium is normally excreted via the kidneys. Therefore, patients with end stage renal failure should avoid food with high potassium contents. Bananas are well known to have high potassium content. However, the 'king of fruits' the durian, has higher potassium content compared to bananas. We describe a case of life threatening hyperkalaemia in a lady with end stage renal failure who ate durians prior to her presentation.

Fulltext Air in the kidney: between emphysematous pyelitis and pyelonephritis

Kua Ch, Abdul Aziz Y

Biomed Imaging Interv J, 2008 Oct;4(4):e24.
PMID: 21611013 DOI: 10.2349/biij.4.4.e24

Presence of air in the kidney can be problematic as the location of the air in different parts of the kidney greatly affects the subsequent management and outcome of the patient. We present here a case of a patient who had emphysematous pyelitis, in which CT scan was able to display presence of air only in the collecting system, thus differentiating this condition from the more fulminant emphysematous pyelonephritis. This leads to a more favourable prognosis and outcome to the patient.

PMID: 19248702 MyJurnal

The association of congenital hepatic fibrosis (CHF) with autosomal recessive polycystic kidney disease (ARPKD) is well known and occurs in approximately 50% of cases. However the association of CHF with autosomal dominant polycystic kidney disease (ADPKD) is less well known and less well documented. We report a child with neonatal onset of hypertension due to ADPKD who later develops portal hypertension due to CHF in childhood. A review of this rare association follows.

Fulltext Acute renal failure in the same hospital ten years apart

Chow YW, Lim BB, Hooi LS

Med J Malaysia, 2007 Mar;62(1):27-32.
PMID: 17682566 MyJurnal

A three month prospective study was carried out in 1994 (8/3/94 - 7/6/94) and late 2004/early 2005 (24/11/2004 - 15/2/2005) among patients with acute renal failure (ARF) (serum creatinine > 0.200 mmol/1). Incidence of ARF had increased from 0.48% (78/16,418) to 1.1% (211/18,697) of admissions between 1994 and 2004. Two thirds of patients were male. Mean age was 57.7 +/- 20.1 years in 1994 and 55.6 +/- 17.8 years in 2004. No difference was noted in causative factors, rate of oliguric ARF (about 10%) and mean peak urea and creatinine. The cause was pre-renal failure in 43.6% in 1994 and 53.5% in 2004. The second commonest cause was sepsis with 41% in 1994 and 37.9% in 2004. One in six patients needed dialysis and peritoneal dialysis was the main dialysis modality (69.2% and 74.3%). Mortality was 56.4% in 1994 and 44.5% in 2004. A quarter of deaths occurred within two days of admission due to severe underlying illness. Mortality among non-oliguric patients decreased from 52.9% in 1994 to 37.0% in 2004 (p = 0.04); for patients from intensive care units it was 78.3% in 1994 and 68.5% in 2004.

Med J Malaysia, 2005 Dec;60(5):647-9.
PMID: 16515119

Anaesthetizing patients with Long QT Syndrome is a major challenge, as the potential for sudden catastrophic cardiovascular collapse is well known. We present a 15-year-old boy with Long QT Syndrome who presented for an elective renal transplant. All electrolyte concentration abnormalities were corrected preoperative and adequate beta-blockade was maintained. The patient was given a target controlled infusion of propofol, together with opioids and atracurium. Anaesthesia was uneventful and the patient was extubated at the end of the surgical procedure.

PMID: 23354221

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.

Fulltext Acute renal failure requiring dialysis--a 5 year series

Hooi LS

Med J Malaysia, 1997 Sep;52(3):251-6.
PMID: 10968094

A retrospective review of 246 patients with established acute renal failure (ARF) needing dialysis from 1990-1994 is reported from Hospital Sultanah Aminah, Johor Bahru. Peritoneal dialysis was more commonly used than haemodialysis or haemofiltration. Patients on mechanical ventilation in Intensive Care Unit (ICU) who were hypercatabolic and fluid overloaded were treated with haemofiltration. Males outnumbered females by a ratio of 1.5:1. The majority were Malays (61.4%). Most patients were from the district of Johor Bahru, but 41.5% were from other districts in the Johor state. The mean age was 47.1 years (SD 18.2). The ARF was caused by acute tubular necrosis in 55.3%, post-renal obstruction in 22.8%, nephrotoxins in 5.7% and other causes in 16.2%. The proportions of patients referred from the medical, surgical and obstetric and gynaecology units were 50.8%, 45.5% and 3.7% respectively. The mortality rate was 48%. Patients with established ARF should be dialysed early as they tolerate uraemia poorly. Prevention is by prompt treatment of patients with sepsis, avoidance of hypovolaemia and nephrotoxic drugs.

Djenkol bean poisoning (djenkolism): an unusual cause of acute renal failure

Segasothy M, Swaminathan M, Kong NC, Bennett WM

Am J Kidney Dis, 1995 Jan;25(1):63-6.
PMID: 7810535

This report describes a patient with acute renal failure that resulted from the ingestion of djenkol beans. Features of acute djenkolism include nausea, vomiting, bilateral loin pain, gross hematuria, and oliguria. The blood urea level was 16.2 mmol/L and the serum creatinine was 460 mumol/L. Phase contrast microscopy of the urinary sediment indicated that the hematuria was nonglomerular. Ultrasound of the kidneys showed slightly enlarged kidneys with no features of obstruction. Renal biopsy showed acute tubular necrosis similar to the single animal study reported in the literature. With conservative therapy, which included rehydration with normal saline and alkalinization of the urine with sodium bicarbonate, the acute renal failure resolved. Based on its chemistry, djenkol bean-associated acute renal failure may be analogous to acute uric acid nephropathy.

Clinical review of acute renal failure: a 5-year experience at Kuala Lumpur

Suleiman AB

Ann Acad Med Singap, 1982 Jan;11(1):32-5.
PMID: 7073225

Over a five year period, 184 patients were treated for acute renal failure. Uraemia was usually treated by peritoneal dialysis, and haemodialysis was reserved for post surgical and hypercatabolic patients. The overall mortality was 33.2% and was highest among surgical patients. These results were similar to previous reports. Peritoneal dialysis was usually effective in controlling uraemia. Uncontrolled sepsis remains a major problem, and septicaemia and gastrointestinal bleeding were adverse factors affecting the outcome. The combination of septicaemia and gastrointestinal bleeding commonly led to a fatal outcome.

Establishment of epithelial and fibroblast cell cultures and cell lines from primary renal cancer nephrectomies

Yap NY, Ong TA, Morais C, Pailoor J, Gobe GC, Rajandram R

Cell Biol Int, 2019 Jun;43(6):715-725.
PMID: 31062478 DOI: 10.1002/cbin.11150

Renal cell carcinoma (RCC) is one of the most lethal urogenital cancers and effective treatment of metastatic RCC remains an elusive target. Cell lines enable the in vitro investigation of molecular and genetic changes leading to renal carcinogenesis and are important for evaluating cellular drug response or toxicity. This study details a fast and easy protocol of establishing epithelial and fibroblast cell cultures or cell lines concurrently from renal cancer nephrectomy tissue. The protocol involves mechanical disaggregation, collagenase digestion and cell sieving for establishing epithelial cells while fibroblast cells were grown from explants. This protocol has been modified from previous published reports with additional antibiotics and washing steps added to eliminate microbial contamination from the surgical source. Cell characterisation was carried out using immunofluorescence and quantitative polymerase chain reaction. Eleven stable epithelial renal tumour cell lines of various subtypes, including rare subtypes, were established with a spontaneous immortalisation rate of 21.6% using this protocol. Eight fibroblast cell cultures grew successfully but did not achieve spontaneous immortalisation. Cells of epithelial origin expressed higher expressions of epithelial markers such as pan-cytokeratin, cytokeratin 8 and E-cadherin whereas fibroblast cells expressed high α-smooth muscle actin. Further mutational analysis is needed to evaluate the genetic or molecular characteristics of the cell lines.
