Fulltext Antibody to hepatitis C virus in thalassemia patients

Isahak I, Baharin R, Hakim AS, Abu Bakar M, George E

Malays J Pathol, 1993 Jun;15(1):85-7.
PMID: 8277796

A specific enzyme immunoassay (EIA) for the diagnosis of hepatitis C virus (HCV) infection was developed by recombinant DNA technology. Abbott HCV EIA was used to detect antibody to HCV (anti-HCV) in non-transfused and multiply-transfused thalassemia patients. None of 11 non-transfused patients had anti-HCV but 3 of 52 (5.8%) multiply-transfused patients had anti-HCV. This study showed that the prevalence rate of HCV infection is low in thalassemia patients. However, it is still important to identify hepatitis C virus infected patients in high risk groups because hepatitis C is associated with chronic hepatitis, cirrhosis and hepatocellular carcinoma.

Cheah PL, Looi LM, Nazarina AR, Mun KS, Goh KL

Malays J Pathol, 2008 Dec;30(2):103-7.
PMID: 19291919 MyJurnal

Transaminase enzymes, alanine (ALT) and aspartate transaminase (AST), have been reported to be raised and implicated to have prognostic value in hepatocellular carcinoma (HCC). Ki67, a marker of cellular proliferative activity, has also been noted to be increased in HCC. A study was conducted at the Department of Pathology, Faculty of Medicine, University of Malaya, Kuala Lumpur to determine the possible association of proliferative activity, as determined by Ki67, with the transaminase enzymes. 31 cases of histologically diagnosed HCC who underwent tumour resection were retrieved from departmental archives. The patients' ages ranged between 40 to 79 years with a mean of 58.3 years. There was a male preponderance with M:F = 2.9:1. Ethnic Chinese formed 83.9% of the cases. 4 microm sections, cut from the formalin-fixed, paraffin-embedded tumour tissue block of each case, were immunohistochemically stained with Ki67 (DAKO monoclonal MIB-1) using the commercial DakoCytomation EnVision+System-HRP kit. The latest ALT and AST levels, assayed within 7 days prior to tumour resection, were retrieved from the patients' case records. 24 (77.4%) HCC demonstrated elevation of either ALT and/or AST. 27 (87.1%) HCC were immunopositive for Ki67. Ki67 immunoexpression was significantly correlated with raised transaminases (p<0.05). Hypothetically, the mechanism by which this phenomenon may occur may simply be release of transaminases due to destruction of hepatocytes by the cancer. Thus rising levels of the transaminases could signal a more rapid growth of the tumour and these routinely performed tests can be of prognostic value in management of HCC patients.

The impact of serum total bilirubin, alanine transaminase and gamma-glutamyl transferase on survival of biliary atresia patients following Kasai procedure

Noor HZ, Noor HZ, Makhmudi A, Gunadi

Med J Malaysia, 2020 05;75(Suppl 1):1-4.
PMID: 32483103

BACKGROUND: Many prognostic factors have been reported for the outcomes of biliary atresia (BA) patients after Kasai procedure, however, it still shows a conflicting result. Our study was to determine the impact of total bilirubin postoperative day-7 and pre-operative ratio (TB7/TB0), gammaglutamyl transferase post-operative day-7 and pre-operative ratio (GGT7/GGT0), and alanine transaminase post-operative day-7 and pre-operative ratio (ALT7/ALT0) on the survival of BA patients following Kasai surgery.
METHODS: We reviewed the medical records of BA patients who underwent Kasai procedure at the Dr. Sardjito Hospital, Indonesia from August 2012 to December 2018. The cut-off values of TB7/TB0, GGT7/GGT0, and ALT7/ALT0 for prediction of patients' survival were determined by receiver operating characteristics (ROC) curves. Log-rank tests were utilised to test the association between cut-off values and overall survival.
RESULTS: In all 46 BA patients (23 males and 23 females) after Kasai procedure were included, consisting of one type 1, 17 type 2A, seven type 2B, and 21 type 3. The cut-off values of TB7/TB0, ALT7/ALT0 and GGT7/GGT0 for overall survival was 0.455 (sensitivity 87.5%, specificity 22.7%, area under curve (AUC) 0.59; 95% Confidence Interval (95%CI): 0.42, 0.75), 0.481 (sensitivity 87.5%, specificity 18.2%, AUC 0.49; 95%CI: 0.31, 0.65), and and 0.31 (sensitivity 79.2%, specificity 9.1%, AUC 0.34; 95%CI: 0.18, 0.50), respectively. However, these cut-off values were not significantly associated with overall survival, with p-values of 0.18, 0.49, and 0.56, respectively.
CONCLUSION: The TB7/TB0, ALT7/ALT0, and GGT7/GGT0 might not predict the overall survival of BA patients after Kasai procedure. Further multicentre studies with a larger sample size is needed to clarify our findings.

Chin JH, Abas HH, Sabariah I

Trop Biomed, 2008 Apr;25(1):9-16.
PMID: 18600199

Orthosiphon stamineus Benth (Family: Lamiaceae) or locally known as Misai Kucing has been widely used in Malaysia for treating kidney problems, gout, and diabetes. This study aims to evaluate the possible toxic effect after following fourteen days oral administration of methanol extract of O. stamineus in female Sprague Dawley (SD) rats. Control groups were treated orally with distilled water (vehicle) while the four test groups were treated up to fourteen days with 0.5 g/kg, 1 g/kg, 3 g/kg and 5 g/kg body weight of methanol extract of O. stamineus respectively. Toxicity of the methanol extract of O. stamineus was evaluated by the incident of lethality, side-cage observation and blood serum biochemical parameters. No lethality or adverse toxic signs were seen during the experimental period. A significant decrease in several serum biochemical parameters i.e. AST and ALT and increase in liver weight was observed in young female SD rat after being fed fourteen days with methanol extract of O. stamineus. No delayed toxic effect and lethality was observed in all rats during fourteen days of recovery period. In conclusion, methanol extract of O. stamineus within these range and treatment duration would not cause any severe toxic effects and organ damages in rats.

Fulltext Prediction of mortality in severe dengue cases

Md-Sani SS, Md-Noor J, Han WH, Gan SP, Rani NS, Tan HL, et al.

BMC Infect Dis, 2018 05 21;18(1):232.
PMID: 29783955 DOI: 10.1186/s12879-018-3141-6

BACKGROUND: Increasing incidence of dengue cases in Malaysia over the last few years has been paralleled by increased deaths. Mortality prediction models will therefore be useful in clinical management. The aim of this study is to identify factors at diagnosis of severe dengue that predicts mortality and assess predictive models based on these identified factors.
METHOD: This is a retrospective cohort study of confirmed severe dengue patients that were admitted in 2014 to Hospital Kuala Lumpur. Data on baseline characteristics, clinical parameters, and laboratory findings at diagnosis of severe dengue were collected. The outcome of interest is death among patients diagnosed with severe dengue.
RESULTS: There were 199 patients with severe dengue included in the study. Multivariate analysis found lethargy, OR 3.84 (95% CI 1.23-12.03); bleeding, OR 8.88 (95% CI 2.91-27.15); pulse rate, OR 1.04 (95% CI 1.01-1.07); serum bicarbonate, OR 0.79 (95% CI 0.70-0.89) and serum lactate OR 1.27 (95% CI 1.09-1.47), to be statistically significant predictors of death. The regression equation to our model with the highest AUROC, 83.5 (95% CI 72.4-94.6), is: Log odds of death amongst severe dengue cases = - 1.021 - 0.220(Serum bicarbonate) + 0.001(ALT) + 0.067(Age) - 0.190(Gender).
CONCLUSION: This study showed that a large proportion of severe dengue occurred early, whilst patients were still febrile. The best prediction model to predict death at recognition of severe dengue is a model that incorporates serum bicarbonate and ALT levels.

Hyperthermic effects of Durio zibethinus and its interaction with paracetamol

Chua YA, Nurhaslina H, Gan SH

Methods Find Exp Clin Pharmacol, 2008 Dec;30(10):739-43.
PMID: 19271022 DOI: 10.1358/mf.2008.30.10.1316830

Because durian (Durio zibethinus), which is known in Southeast Asia as "the king of fruits", is thought to have special body-warming properties, it should not be consumed with paracetamol due to a risk of toxic effects. The claim of warming properties, however, has not been scientifically proven. This study was conducted to investigate durian's hyperthermic effect and its toxicity when consumed together with paracetamol in rats. Five groups of rats (n=6) were fed with: 1) distilled water (4 ml/250 g), 2) homogenized durian (4 g/250 g), 3) paracetamol solution (2400 mg/kg), 4) durian (4 g/250 g) followed by paracetamol solution (2400 mg/kg), or 5) prazosin solution (15 mg/kg, pregavaged) followed 1 h later by durian (4 g/250 g) and paracetamol solution (2400 mg/kg). Rectal temperature, systolic blood pressure and serum alanine aminotransferase (ALT) levels were taken from each rat at baseline and after the various administrations at 1, 2 and 5 h. Our results showed that the body temperature of rats in the durian-treated group was not significantly elevated when compared to the control. However, there was a significant decrease in body temperature over time in animals from groups 4 and 5. We did not, however, observe a consistent pattern of blood pressure change. Serum chemical analysis for ALT also did not show any significant change in any of the groups. In conclusion, contrary to what some believe, even though durian was found to increase body temperature in some rats, this increment was not significant. Rats receiving the durian-paracetamol combination showed a significant drop in body temperature, which may explain the belief that the two mixtures are toxic. However, the exact mechanism of toxicity is still unknown.

Ooi ET, Ganesananthan S, Anil R, Kwok FY, Sinniah M

Med J Malaysia, 2008 Dec;63(5):401-5.
PMID: 19803300

This is a retrospective study of the gastrointestinal symptoms, signs and laboratory parameters in adult dengue patients admitted to Kuala Lumpur Hospital from 1st December 2004 to 31st December 2004. Clinical and laboratory parameters that may predict the need for intensive care were investigated. Six hundred sixty-six patients with clinical and biochemical features consistent with dengue infection were identified. Patients were stratified into those who required intensive care and those who were managed in non high dependency wards. Serum alanine aminotransaminase (ALT) levels were normal in 22.8% of patients and 5.9% of patients had acute fulminant hepatitis. More patients with dengue haemorrhagic fever (DHF) had elevated ALT levels as compared to patients with classic dengue fever (DF) (p = 0.012). Patients with DF had a statistically significant lower mean ALT level as compared to patients with DHF. Abdominal pain (p = 0.01) and tenderness (p<0.001), gastrointestinal bleed (p<0.001), jaundice (p<0.001), hepatomegaly (p<0.001) and ascites (p<0.001) were predictors of need for intensive care. We conclude that gastrointestinal manifestations are very common in dengue patients. Presence of abdominal pain and tenderness, gastrointestinal bleed, jaundice, hepatomegaly and ascites can be used to triage patients requiring intensive care.

PMID: 26826813

Brewers' rice is one of abundant agricultural waste products in the rice industry. The present study is designed to investigate the potential of brewers' rice to inhibit the development of aberrant crypt foci (ACF) in colon of azoxymethane (AOM)-treated rats. The effects on the attenuation of hepatic toxicity and kidney function enzymes were also evaluated. Male Sprague-Dawley rats were randomly divided into five groups: (G1) normal; (G2) AOM alone; and (G3), (G4), and (G5), which were AOM fed with 10%, 20%, and 40% (w/w) of brewers' rice, respectively. The rats in group 2-5 were injected intraperitoneally with AOM (15 mg/kg body weight) once weekly for two weeks. After 8 weeks of treatment,the total number of ACF/colon and the number of ACF in the distal and middle colon were significantly reduced in all treatment groups compared to G2 (p<0.05). Brewers' rice decreased the number of ACF with dysplastic morphology in a dose-dependent manner. Alkaline phosphatase (ALP) level in G5 was significantly lower compared to the G2 (p<0.05). In conclusion, this study found the potential value of brewers' rice in reducing the risk of cancer susceptibility in colon.

Wahid SF, Sanusi S, Zawawi MM, Ali RA

Southeast Asian J. Trop. Med. Public Health, 2000 Jun;31(2):259-63.
PMID: 11127322

The impact of dengue on liver function was studied on fifty serologically confirmed dengue cases admitted to Hospital Universiti Kebangsaan Malaysia (HUKM). Twenty-five of these patients had classic dengue fever (DF) and 25 had grade 1 or 2 dengue hemorrhagic fever (DHF). There were more (60%) DHF patients with hepatomegaly compared to DF (40%) but the difference was not statistically significant. Analysis of the liver profile showed that liver dysfunction was commoner in DHF compared to DF, indicating that the degree of liver impairment may be related to the severity of DHF. Hyperbilirubinemia was noted in 3 (12%) DHF and 2 (8%) DF patients. The mean (range) serum bilirubin was higher in DHF [14.2(5-50) micromol/l] compared to DF [10.9(5-30) micromol/l)] (p > 0.05). Elevated levels of serum alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were observed more frequently in DHF (20 and 12 patients respectively) compared to DF (16 and 8 patients respectively). Nine (36%) DHF and 6 (24%) DF patients had concomitant elevation of ALT and ALP levels. The mean (range) serum ALT levels were 109.3(23-325) U/l in DHF and 90.8(13-352) U/l in DF (p > 0.05). The mean (range) serum ALP levels were 102.2(15-319) U/l in DHF and 93.3(34-258) U/l in DF (p > 0.05). The ALT and ALP levels were significantly higher in DHF patients with spontaneous bleeding than those without bleeding (p < 0.05) None of the patients developed fulminant hepatitis. The immunoregulatory cells, which include the T (CD3), B (CD 19), CD4, CD8, CD5 and natural killer (NK) cells were significantly lower in DHF compared to DF patients (p < 0.05). However, the reduction in these cell counts did not correlate with the liver dysfunction seen in DHF patients. In conclusion, hepatomegaly and liver dysfunction were commoner in DHF compared to DF.

Effects of copper overload on hepatic lipid peroxidation and antioxidant defense in rats

Zhang SS, Noordin MM, Rahman SO, Haron J

Vet Hum Toxicol, 2000 Oct;42(5):261-4.
PMID: 11003114

The influence of copper (Cu) overload on hepatic lipid peroxidation and antioxidation defense capacity was studied by overloading rats with copper sulphate orally (500 mg Cu/kg bw) 5 d/w for 8 w. Malondialdehyde (MDA), Cu-Zn superoxide dismutase (SOD), and Se-glutathione peroxidase (GSH-Px) were measured in serum and liver homogenate at 2, 4 and 8 w of dosing. Liver Cu concentration and alanine aminotransferase (ALT) activity were also determined. As Cu loading progressed, there were multiparameter changes with significant ALT elevation, increased MDA concentrations in serum and liver homogenate, and dramatic declines of SOD and GSH-Px activities in erythrocytes and whole blood respectively, along with marked elevation of hepatic Cu in the Cu-dosed group. Excessive Cu accumulation in the liver depressed SOD and GSH-Px activities and resulted in high MDA in serum and liver homogenate due to the lipid peroxidation induced by the Cu overload.

The value of liver function tests in hepatocellular carcinoma

Lopez JB, Balasegaram M, Thambyrajah V, Timor J

Malays J Pathol, 1996 Dec;18(2):95-9.
PMID: 10879229

This study was undertaken to see if liver function tests (LFT) served a worthwhile purpose in the investigation of hepatocellular carcinoma (HCC). Sera from 80 HCC, 76 benign liver disease (BLD) and 152 healthy adult (HA) subjects were assayed for alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT), aspartate aminotransferase (AST), alanine aminotransferase and lactate dehydrogenase, bilirubin and albumin. Cut-off values were determined from the HA. ALP, GGT, AST and albumin were abnormal in about 90% of the HCC. With the exception of bilirubin, the LFT were abnormal more frequently in HCC than in chronic hepatitis and cirrhosis, the conditions which preceed it. Raised ALP in the presence of normal bilirubin was more often a feature of HCC than BLD although this relationship was not statistically significant. It seems unlikely that LFT serve a useful function in HCC.

Treatment of subperiodic Brugia malayi infection with a single dose of ivermectin

Mak JW, Navaratnam V, Grewel JS, Mansor SM, Ambu S

Am J Trop Med Hyg, 1993 Apr;48(4):591-6.
PMID: 8480868

A clinical trial on the efficacy of a single oral dose of ivermectin at 20, 50, 100, and 200 micrograms/kg was carried out in 40 subjects with subperiodic Brugia malayi microfilaremia. There was no significant difference in the clearance of microfilaremia in the four treatment groups, and the lowest geometric mean microfilarial count (GMC) achieved in the 40 subjects was 8.8/ml or 8.3% of the initial count (106.1/ml), at two weeks post-treatment. The GMC started to increase at one month post-treatment and by six months was 22.2% of the initial GMC. Only 27.5%, 23.1%, 15.0%, and 18.9% of subjects were amicrofilaremic at two, four, 12, and 24 weeks post-treatment, respectively. Mild fever in 35% of the subjects was the primary side reaction and was more common in those with microfilarial counts > or = 500/ml (85.7%) than in those with counts < 500/ml (32%). The clearance of B. malayi microfilaremia by ivermectin was less rapid than that reported for Wuchereria bancrofti. The smaller number of side reactions encountered in the present study compared with those reported for bancroftian filariasis is probably related to the lower microfilarial density in the present subjects. Since ivermectin at a single oral dose of 20-200 micrograms/kg can reduce the GMC to less than 10% at two weeks and maintain it below 25% of the initial level even at six months post-treatment, it is recommended that the drug be seriously evaluated for use in the control of brugian filariasis.

Tan DS, Dimitrakakis M, Zaini Rahman M, Fang R, Collett D, Ooi BG, et al.

Southeast Asian J. Trop. Med. Public Health, 1986 Jun;17(2):205-8.
PMID: 3024325

Icteric patients with clinical and biochemical evidence of liver disease, admitted into various hospitals in Malaysia, were investigated to determine the cause of their infection. Of these patients, 11.0% (16/145) were found positive for IgM anti-HAV (EIA), 4.1% (6/145) for IgM anti-HBc (EIA), 1.0% (1/102) for IgM anti-CMV (ELISA), 17.2% (16/64) for rising titres of leptospiral agglutinin, and none for heterophile antibody of EBV. Hepatitis NANB accounted for 67.9% of cases. The mean serum transaminases (ALT and AST) values in patients with hepatitis A and B were higher (more than 500IU) than in patients with leptospirosis or non-A, non-B hepatitis, whereas serum bilirubin levels were higher in patients with hepatitis A and leptospirosis than in patients with hepatitis B.

Biochemical studies in Presbytis cristata infected with subperiodic Brugia malayi

Choong MF, Mak JW

Trop. Med. Parasitol., 1991 Mar;42(1):71-2.
PMID: 1675809

The Presbytis cristata--Brugia malayi model, now established as a reliable non-human primate model for the experimental screening of potential filaricides, was monitored at monthly intervals for changes in the liver and renal function tests and also for alkaline phosphatase levels during infection. Animals infected with 200-400 infective larvae became patient at 50-90 days post-infection and geometric mean microfilarial counts were above 1000 per ml from the fourth month onwards. There were no significant changes in the biochemical parameters monitored throughout the period of observation. This is an important observation as any changes seen in these parameters during experimental drug studies can be attributed to drug reaction or toxicity and this will be invaluable in decision making as to drug safety.

Antivenom in sea-snake bit poisoning

Reid HA

Lancet, 1975 Mar 15;1(7907):622-3.
PMID: 47960

Among a series of 101 patients bitten by sea-snakes in Malaya in the years 1957-64, 80% were fishermen. Bathers and divers are occasionally bitten. Before sea-snake antivenom became available the mortality-rate (despite the high toxicity of sea-snake venom) was only 10%; however, of 11 with serious poisoning, 6 died. Subsequently 10 patients with serious poisoning received specific sea-snake antivenom; 2 patients, admitted moribund, temporarily improved but died, and 8 patients recovered dramatically. In serious poisoning the suitable dosage of intravenous sea-snake antivenom is 3000-10,000 units; in mild poisoning 1000-2000 units should suffice.

Gamma-glutamyltransferase, alanine transaminase and aspartate transaminase levels and the diagnosis of gestational diabetes mellitus

Tan PC, Aziz AZ, Ismail IS, Omar SZ

Clin Biochem, 2012 Oct;45(15):1192-6.
PMID: 22659058 DOI: 10.1016/j.clinbiochem.2012.05.025

OBJECTIVES: To evaluate gamma-glutamyltransferase (GGT), alanine transaminases (ALT) and aspartate transaminases (AST) levels and prevalent gestational diabetes mellitus (GDM).
DESIGN AND METHODS: Random plasma glucose, GGT, ALT and AST and the 50-g glucose challenge test were done on antenatal women followed by diagnostic 3-point 75-g oral glucose tolerance test within two weeks. GDM was diagnosed by ADA (2011) criteria.
RESULTS: The GDM rate was 12.2% (319/2610). Mean GGT level was higher in GDM women, 18 ± 12 vs. 16 ± 11 IU/L; P=0.03. The risk for GDM was higher for women in the highest GGT quartile band compared to the lowest: RR 1.35 95%CI 1.0-1.8; P=0.04. However, after adjustment for confounders, GGT was no longer associated with GDM. There was no correlation between ALT and AST levels and GDM.
CONCLUSIONS: Liver transaminases do not predict GDM in contrast to type 2 diabetes.

The Hepatoprotective Effect of Clidemia hirta against Carbon Tetrachloride (CCl4)-Induced Oxidative Stress and Hepatic Damage in Mice

Amzar N, Iqbal M

J Environ Pathol Toxicol Oncol, 2017;36(4):293-307.
PMID: 29431062 DOI: 10.1615/JEnvironPatholToxicolOncol.2017019824

Liver diseases still represents a major health burden worldwide. Moreover, medicinal plants have gained popularity in the treatment of several diseases, including liver disease. Clidemia hirta possesses many medicinal properties for healing several diseases and for health maintenance. However, the hepatoprotective effects and antioxidative potential of C. hirta have not been fully investigated. In the present study, we evaluated the hepatoprotective and antioxidative potential of C. hirta against carbon tetrachloride (CCl4)-induced liver injuries and oxidative damage in a murine model. Various biochemical changes associated with liver damage and oxidative stress were measured. The mice were pretreated for 14 consecutive days with aqueous extract of C. hirta at selected doses (150 mg/kg body weight [b.w.], 300 mg/kg b.w. and 600 mg/kg b.w.) followed by two doses of CCl4 (1.0 mL/kg b.w.) orally on days 14 and 15. All animals were sacrificed 24 hours after the last dose of CCl4 or saline. Blood and liver tissues were taken quickly for biochemical and histopathological studies to assess the derangement in the functioning of liver. The development of oxidative stress was observed through the escalation of hepatic lipid peroxidation, depletion of glutathione, and reduced antioxidant enzymes (glutathione peroxidase, glutathione reductase, catalase, glutathione S-transferase and quinone reductase). Hepatic damage was evaluated by measuring serum transaminase (ALT and AST). In addition, CCl4-induced hepatic damage was further evaluated using histopathological assessments. However, most of these changes were dependently ameliorated by the pretreatment of mice with a C. hirta dose. These results indicate that the hepatoprotective effect of C. hirta might be due to its antioxidant and free-radical scavenging properties.
