    PMID: 28503272
    Von Hippel-Lindau (VHL) disease is a rare autosomal dominantly inherited multisystem disorder characterised by the development of a variety of benign and malignant tumours. We report a case of VHL disease that was inherited by a daughter from her father, who both presented at a young age with progressive headache and were found to have a posterior fossa haemangioblastoma (HB) on magnetic resonance imaging (MRI). Multiple benign pancreatic and renal cysts were also noted in both patients.

    A 6-year-old intact Persian cat was presented for the primary complaint of inappetence and weight loss. Irregular surface of
    kidneys was palpated during physical examination. Abdominal radiograph findings were indicative of renomegaly. Ultrasonography
    revealed multiple anaechoic structures within the renal parenchyma. The cortex, medulla and renal pelvis were unable to be
    differentiated. Both radiographic and ultrasonographic findings were suggestive of polycystic kidney disease. Blood test revealed
    normochromic, normocytic anaemia with azotaemia whereas urinalysis findings were hypostenuria and proteinuria, consistent of
    chronic kidney disease due to polycystic kidney. Ultrasound is a useful antemortem diagnostic tool to diagnose polycystic kidney
    disease in cats.

    Bhargava V, Jasuja S, Tang SC, Bhalla AK, Sagar G, Jha V, et al.
    Nephrology (Carlton), 2021 Nov;26(11):898-906.
    PMID: 34313370 DOI: 10.1111/nep.13949
    BACKGROUND: Peritoneal dialysis (PD) as a modality of kidney replacement therapy (KRT) is largely underutilized globally. We analyzed PD utilization, impact of economic status, projected growth and impact of state policy(s) on PD growth in South Asia and Southeast Asia (SA&SEA) region.

    METHODS: The National Nephrology Societies of the region responded to a questionnaire on KRT practices. The responses were based on the latest registry data, acceptable community-based studies and societal perceptions. The representative countries were divided into high income and higher-middle income (HI & HMI) and low income and lower-middle income (LI & LMI) groups.

    RESULTS: Data provided by 15 countries showed almost similar percentage of GDP as health expenditure (4%-7%). But there was a significant difference in per capita income (HI & HMI -US$ 28 129 vs. LI & LMI - US$ 1710.2) between the groups. Even after having no significant difference in monthly cost of haemodialysis (HD) and PD in LI & LMI countries, they have poorer PD utilization as compared to HI & HMI countries (3.4% vs. 10.1%); the reason being lack of formal training/incentives and time constraints for the nephrologist while lack of reimbursement and poor general awareness of modalities has been a snag for the patients. The region expects ≥10% PD growth in the near future. Hong Kong and Thailand with 'PD first' policy have the highest PD utilization.

    CONCLUSION: Important deterrents to PD underutilization were lack of PD centric policies, lackadaisical patient/physician's attitude, lack of structured patient awareness programs, formal training programs and affordability.

  4. Fulltext Moxibustion (ArtemisiaPlant at Acupuncture Point) as Alternative Therapy in Hypertension: A Promising Approach
    Siddiqui MJ, Kamarudin MFB, Mohammed Al-Shami AK, Mat So'ad SZ, Jamshed SQ
    J Pharm Bioallied Sci, 2017 Oct-Dec;9(4):279-281.
    PMID: 29456380 DOI: 10.4103/jpbs.JPBS_24_17
    Hypertension is a pathological condition in which the blood pressure is higher than under normal physiological conditions, i.e., 140/90 mmHg or higher. Blood pressure is measured as the force exerted by the blood pumped by the heart against the walls of arteries (aorta) and distributed throughout the body. Use of complementary and alternative medicine as a cure for hypertension is a common phenomenon because of the high risk of cardiovascular complications and kidney diseases caused by conventional Western medicine. It is reported that high blood pressure causes ~49% of myocardial infarction and 62% of strokes. Effective treatment of hypertension is restricted by adverse effects and cost of the medication. Moxibustion is the application of heat by burning a small bundle of tightly bound moxa, to targeted acupoint, and sometimes it is used along with acupuncture. Encouraging results have been reported on randomized trials indicating the efficacy of moxibustion. But more controlled clinical trials are required to further establish the potential efficacy of moxibustion approach in hypertension.

  8. Fulltext An Asian validation of the TIMI risk score for ST-segment elevation myocardial infarction
    Selvarajah S, Fong AY, Selvaraj G, Haniff J, Uiterwaal CS, Bots ML
    PLoS One, 2012;7(7):e40249.
    PMID: 22815733 DOI: 10.1371/journal.pone.0040249
    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.

  9. A modified in situ RT-PCR method for localizing fungal-specific gene expression in Candida-infected mice renal cells
    Yong VC, Ong KW, Sidik SM, Rosli R, Chong PP
    J Microbiol Methods, 2009 Nov;79(2):242-5.
    PMID: 19737582 DOI: 10.1016/j.mimet.2009.08.019
    In situ Reverse Transcriptase PCR (in situ RT-PCR) can amplify mRNA and localize gene expression in cells. However, this method is not feasible in fungi as the thick fungal cell wall constitutes a barrier to this procedure. We developed a two step in situ RT-PCR procedure which enabled the detection and localization of Candida tropicalis mRNA expression in formalin-fixed, paraffin-embedded (FFPE) mouse kidney sections. This in situ hybridization study revealed the first direct evidence for deposition of Candida tropicalis secreted aspartic proteinase 2 (CtSAP2) in the tip of pseudohyphae and its involvement in acute systemic candidiasis. We conclude that in situ RT-PCR can be successfully applied to FFPE tissues and will offer new perspectives in studying gene expression in Candida species.

  10. The pattern of amyloidosis in Malaysia
    Looi LM
    Malays J Pathol, 1994 Jun;16(1):11-3.
    PMID: 16329569
    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.

  11. Clinical pharmacokinetics, toxicity and cost effectiveness analysis of aminoglycosides and aminoglycoside dosing services
    Mathews A, Bailie GR
    J Clin Pharm Ther, 1987 Oct;12(5):273-91.
    PMID: 3119606
    This article reviews the clinical pharmacokinetics, clinical toxicity and cost-effectiveness analysis of aminoglycosides and of dosing services for aminoglycosides. The reader is referred elsewhere for a review of the pharmacology, antimicrobial spectrum of activity and clinical use of these drugs. A critique of the more commonly used methods of aminoglycoside dosage determinations is included, based on the inter-individual variation in aminoglycoside disposition parameters. The advantages and disadvantages of arbitrary, predictive, and pharmacokinetic methods of dosing determination are summarized. Justification for the routine determination of serum aminoglycoside concentrations is reviewed. We review the lack of standardization of definitions for aminoglycoside-associated nephrotoxicity in published studies, and studies which illustrate these differences are highlighted. Evidence for the association between serum aminoglycoside concentrations and nephrotoxicity is examined. Ototoxicity is similarly reviewed. The concept of cost-effectiveness analysis is examined extensively in this review. We discuss the literature concerning the cost benefit analysis of drug dosing services.

    Prathap K, Looi LM
    Ann Acad Med Singap, 1982 Jan;11(1):52-6.
    PMID: 7073229
    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%).

  14. Chlorogenic acid attenuates kidney fibrosis via antifibrotic action of BMP-7 and HGF
    Yunus J, Salman M, Lintin GBR, Muchtar M, Sari DCR, Arfian N, et al.
    Med J Malaysia, 2020 05;75(Suppl 1):5-9.
    PMID: 32471962
    BACKGROUND: Kidney fibrosis, characterised by tubulointerstitial fibrosis, is a histological landmark of chronic kidney disease. The body attempts to compensate for progressive detrimental process of kidney fibrosis by producing antifibrotic substances, such as bone morphogenetic protein-7 (BMP-7) and hepatocyte growth factor (HGF). Chlorogenic acid is known to have renoprotective and antifibrotic properties. This study aims to evaluate the effect of chlorogenic acid on unilateral ureteral obstruction (UUO)-induced kidney fibrosis mice model.

    METHODS: This study was a quasi-experimental with posttestonly control group design. Twenty-five adult male Swiss Webster mice were randomly divided into five groups: shamoperated group (SO), UUO-control day-7 (U7), UUO-control day-14 (U14), UUO-chlorogenic acid day-7 (UC7), and UUOchlorogenic acid day 14 (UC14). Myofibroblasts were identified by immunohistochemical staining of alphasmooth muscle actin (α-SMA) while collagen fibers were identified by Sirius Red staining. Both data were presented as area fraction. BMP-7 and HGF mRNA expressions were assessed by reverse transcription PCR (RT-PCR). Data were quantified using ImageJ software.

    RESULTS: UUO-control groups (U7 and U14) showed higher α- SMA-immunopositive (6.52±1.33, 18.24±1.39 vs. 0.22±0.01; p<0.05) and Sirius Red-positive area fractions (6.61±0.8, 12.98±2.31 vs. 0.62±0.10; p<0.05), lower BMP-7 (1.02±0.47, 1.18±0.65 vs. 2.09±0.87; p<0.05) and HGF mRNA expressions (1.06±0.31, 0.89±0.14 vs. 1.88±0.81; p<0.05) compared to SO group. UUO-chlorogenic acid groups (UC7 and UC14) showed lower α-SMA-immunopositive (1.24±0.37, 4.58±0.61; p<0.05) and Sirius Red-positive area fractions (4.76±1.03, 3.72±0.54; p<0.05), higher BMP-7 (1.84±0.49, 2.19±0.43; p<0.05) and HGF (1.58±0.38; p>0.05, 1.84±0.42; p<0.05) mRNA expressions compared to UUO-control groups. UUOchlorogenic acid groups showed BMP-7 and HGF mRNA expressions that were not significantly different from the SO group.

    CONCLUSION: Chlorogenic acid administration prevents kidney fibrosis in UUO mice model through modulating antifibrotic pathway.

    Zahari Sham SY, C Thambiah S, Samsudin IN, Lim SM
    Malays J Pathol, 2017 Dec;39(3):311-315.
    PMID: 29279596 MyJurnal
    Multiple myeloma is a type of plasma cell dyscrasia, characterised by presence of paraprotein or monoclonal (M)-protein in serum or urine. The M-protein may consist of an intact immunoglobulin, the heavy chain only or the light chain only. The latter, designated as light chain multiple myeloma (LCMM) makes up almost 20% of myelomas. Clinical manifestation is often heralded by hypercalcaemia, renal impairment, normocytic normochromic anaemia and bone lesions, reflecting end-organ damage, collectively known as the acronym CRAB. In particular, free light chain nephrotoxicity accounts for the high prevalence of renal impairment seen in LCMM. This case illustrates a typical presentation of LCMM with focal discussion on its initial and diagnostic, as well as prognostic biochemical investigations.

  16. Fulltext Rhabdomyolysis and acute renal failure following a switchover of therapy between two fibric acid derivatives
    Kamaliah MD, Sanjay LD
    Singapore Med J, 2001 Aug;42(8):368-72.
    PMID: 11764054
    Drug induced myopathy has been reported with the use of fibric acid derivatives, hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors and nicotinic acid. Over the last three decades, hypolipemiants like fibric acid derivatives and statins have been increasingly recognised as causes of rhabdomyolysis and acute renal failure especially during combination therapy and in the presence of underlying renal impairment. We report two cases of bezafibrate-induced rhabdomyolysis in patients with underlying coronary artery disease and pre-existing renal impairment. Both patients developed rhabdomyolysis leading to acute renal failure soon after their hyperlipidaemia treatment was changed from gemfibrozil to bezafibrate. There were no intercurrent illnesses or co-administration of other lipid lowering drugs in both patients. Even though both drugs belong to the same fibric acid derivatives group, these patients developed the complication only after a switchover of therapy.

  17. The effects of ethnicity on disease patterns in 472 Orientals with systemic lupus erythematosus
    Thumboo J, Fong KY, Chng HH, Koh ET, Chia HP, Leong KH, et al.
    J Rheumatol, 1998 Jul;25(7):1299-304.
    PMID: 9676760
    OBJECTIVE: 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.
    METHODS: 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.
    RESULTS: 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.
    CONCLUSION: 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.

  20. Diallyl sulphide, a component of garlic, abrogates ferric nitrilotriacetate-induced oxidative stress and renal damage in rats
    Ansar S, Iqbal M, AlJameil N
    Hum Exp Toxicol, 2014 Dec;33(12):1209-16.
    PMID: 24596035 DOI: 10.1177/0960327114524237
    Ferric nitrilotriacetate (Fe-NTA) induces tissue necrosis as a result of lipid peroxidation (LPO) and oxidative damage that leads to high incidence of renal carcinomas. The present study was undertaken to evaluate the effect of diallyl sulphide (DAS) against Fe-NTA-induced nephrotoxicity. A total of 30 healthy male rats were randomly divided into 5 groups of 6 rats each: (1) control, (2) DAS (200 mg kg(-1)), (3) Fe-NTA (9 g Fe kg(-1)), (4) DAS (100 mg kg(-1)) + Fe-NTA (9 mg Fe kg(-1)) and (5) DAS (200 mg kg(-1)) + Fe-NTA (9 mg Fe kg(-1)). Fe-NTA + DAS-treated groups were given DAS for a period of 1 week before Fe-NTA administration. The intraperitoneal administration of Fe-NTA enhanced blood urea nitrogen and creatinine levels with reduction in levels of antioxidant enzymes. However, significant restoration of depleted renal glutathione and its dependent enzymes (glutathione reductase and glutathione-S-transferase) was observed in DAS pretreated groups. DAS also attenuated Fe-NTA-induced increase in LPO, hydrogen peroxide generation and protein carbonyl formation (p < 0.05). The results indicate that DAS may be beneficial in ameliorating the Fe-NTA-induced renal oxidative damage in rats.
