    Thayan R, Huat TL, See LL, Tan CP, Khairullah NS, Yusof R, et al.
    Trans R Soc Trop Med Hyg, 2009 Apr;103(4):413-9.

    Dengue infection is a major public health problem affecting millions of people living in tropical countries. With no suitable vaccines and specific antiviral drugs, treatment for dengue is usually symptomatic and supportive. Early diagnosis and recognition of severe disease is therefore crucial for better management of the patient. Two-dimension electrophoresis was used to identify disease-associated proteins that can be used for diagnosis and as drug targets for treatment. Two markers, identified by mass spectrometry analysis as alpha1-antitrypsin and NS1 proteins were found to be upregulated in dengue fever (DF; n=10) and dengue haemorrhagic fever (DHF; n=10) patients compared with healthy individuals (n=8). Both alpha1-antitrypsin and NS1 proteins were overexpressed two-fold in DHF patients compared with DF patients. Our study suggests that alpha1-antitrypsin and NS1 protein could be used as biomarkers as early indicators of DHF risk among patients with suspected dengue infection.

    Suleiman S, Kamaliah D, Nadeem A, Naing NN, Che Maraina CH
    Int J Rheum Dis, 2009 Jul;12(2):100-6.
    PMID: 20374326 DOI: 10.1111/j.1756-185X.2009.01391.x
    AIM: To measure the level of anti-nucleosome antibodies in systemic lupus erythematosus (SLE) patients, to determine the sensitivity and the specificity of these antibodies in the diagnosis of the disease and to evaluate the relationship between the levels of anti-nucleosome antibodies, anti-dsDNA (double-stranded DNA) and SLE disease activity.
    METHODS: A cross-sectional study was conducted. All patients attended either a medical specialist clinic or were admitted to the medical wards of Hospital Universiti Sains Malaysia with the diagnosis of SLE (n = 90), other connective tissue diseases (n = 45) or were normal controls (n = 90) within the period from July 2004 until September 2005. They were tested for anti-nucleosome antibodies by enzyme-linked immunosorbent assay and anti-DNA antibodies by immunofluorescence. SLE disease activity was evaluated by SLE disease activity index (SLEDAI) score.
    RESULTS: Out of 90 SLE patients, anti-nucleosome antibodies were positive in 47 (52.2%) patients, whereas these antibodies were positive in three (6.7%) patients with other connective tissue diseases. Anti-dsDNA antibodies were positive in 33 (36.7%) SLE patients, whereas these antibodies were positive in four (8.9%) patients with other connective tissue diseases. Anti-nucleosome antibodies were positive in 40 (97.6%) patients with active SLE, whereas these antibodies were positive in seven (14.3%) patients with inactive SLE. Anti-nucleosome antibodies had a stronger correlation than anti-dsDNA antibodies with SLEDAI score. There was a significant association between anti-nucleosome antibodies and disease activity.
    CONCLUSION: Anti-nucleosome antibodies test is highly sensitive and specific for the diagnosis of SLE, especially when the anti-dsDNA antibodies are absent. They are additional disease activity markers in the assessment of SLE disease activity.

  5. CXCL 9 and CXCL 10 as Sensitive markers of disease activity in patients with rheumatoid arthritis
    Kuan WP, Tam LS, Wong CK, Ko FW, Li T, Zhu T, et al.
    J Rheumatol, 2010 Feb;37(2):257-64.
    PMID: 20032101 DOI: 10.3899/jrheum.090769
    OBJECTIVE:
    To assess whether serum levels of CC and CXC chemokines correlate with disease activity in patients with rheumatoid arthritis (RA), and to determine whether these effects predict clinical response.

    METHODS:
    Serum levels of the chemokines CC (CCL2, CCL5) and CXC (CXCL8, CXCL9, CXCL10) were quantified at baseline and after 12 weeks of treatment with disease-modifying antirheumatic drugs or biologic agents in 28 patients using flow cytometry. Serum from 40 healthy individuals was collected for comparison at baseline. Response to treatment was classified according to the European League Against Rheumatism (EULAR) response criteria. Remission of disease was defined as a Disease Activity Score < 2.6.

    RESULTS:
    The baseline serum concentrations of CC and CXC chemokines were significantly elevated in patients with active RA compared to healthy controls (p < 0.05) except for CCL2. Significant improvement in all disease activity measurements was observed after 12 weeks of treatment. Seventeen (60.7%) patients achieved good to moderate response based on the EULAR response criteria, and 5 (17.9%) patients achieved remission. The improvement in clinical activity in patients with RA was accompanied by a significant reduction in the serum concentration of CXCL9 and CXCL10 (p < 0.001). A significant reduction in the serum level of CXCL10 was also observed in the group that achieved EULAR response. Serum concentration of CCL5 remained significantly elevated in patients with RA (n = 5) who achieved remission compared to the healthy controls (p < 0.05).

    CONCLUSION:
    Serum concentration of CXCL9 and CXCL10 may serve as sensitive biomarkers for disease activity in patients with RA.

  6. Reexamination of risk criteria in dengue patients using the self-organizing map
    Faisal T, Taib MN, Ibrahim F
    Med Biol Eng Comput, 2010 Mar;48(3):293-301.
    PMID: 20016950 DOI: 10.1007/s11517-009-0561-x
    Even though the World Health Organization criteria's for classifying the dengue infection have been used for long time, recent studies declare that several difficulties have been faced by the clinicians to apply these criteria. Accordingly, many studies have proposed modified criteria to identify the risk in dengue patients based on statistical analysis techniques. None of these studies utilized the powerfulness of the self-organized map (SOM) in visualizing, understanding, and exploring the complexity in multivariable data. Therefore, this study utilized the clustering of the SOM technique to identify the risk criteria in 195 dengue patients. The new risk criteria were defined as: platelet count less than or equal 40,000 cells per mm(3), hematocrit concentration great than or equal 25% and aspartate aminotransferase (AST) rose by fivefold the normal upper limit for AST/alanine aminotransfansferase (ALT) rose by fivefold the normal upper limit for ALT. The clusters analysis indicated that any dengue patient fulfills any two of the risk criteria is consider as high risk dengue patient.

    Teng KT, Voon PT, Cheng HM, Nesaretnam K
    Lipids, 2010 May;45(5):385-92.
    PMID: 20437207 DOI: 10.1007/s11745-010-3416-1
    Knowledge about the effects of dietary fats on subclinical inflammation and cardiovascular disease risk are mainly derived from studies conducted in Western populations. Little information is available on South East Asian countries. This current study investigated the chronic effects on serum inflammatory markers, lipids, and lipoproteins of three vegetable oils. Healthy, normolipidemic subjects (n = 41; 33 females, 8 males) completed a randomized, single-blind, crossover study. The subjects consumed high oleic palm olein (HOPO diet: 15% of energy 18:1n-9, 9% of energy 16:0), partially hydrogenated soybean oil (PHSO diet: 7% of energy 18:1n-9, 10% of energy 18:1 trans) and an unhydrogenated palm stearin (PST diet: 11% of energy 18:1n-9, 14% of energy 16:0). Each dietary period lasted 5 weeks with a 7 days washout period. The PHSO diet significantly increased serum concentrations of high sensitivity C-reactive protein compared to HOPO and PST diets (by 26, 23%, respectively; P < 0.05 for both) and significantly decreased interleukin-8 (IL-8) compared to PST diet (by 12%; P < 0.05). In particular PHSO diet, and also PST diet, significantly increased total:HDL cholesterol ratio compared to HOPO diet (by 23, 13%, respectively; P < 0.05), with the PST diet having a lesser effect than the PHSO diet (by 8%; P < 0.05). The use of vegetable oils in their natural state might be preferred over one that undergoes the process of hydrogenation in modulating blood lipids and inflammation.

    Ma NH, Teh CL, Rapaee A, Lau KB, Fong AY, Hi S, et al.
    Int J Rheum Dis, 2010 Aug;13(3):223-9.
    PMID: 20704618 DOI: 10.1111/j.1756-185X.2010.01533.x
    INTRODUCTION: Rheumatoid arthritis (RA) patients who have active disease with longer disease duration have been reported to have increased risk of cardiovascular events compared to the normal population.
    OBJECTIVE: The primary aim of our study is to ascertain the prevalence of significant asymptomatic coronary artery disease (CAD) in Asian RA patients who are in remission using multi-detector computed tomography (MDCT). The secondary aims of our study are the usage of pulse wave velocity and the biomarkers N-terminal pro-brain natriuretic peptide (NT-proBNP) and high-senstivity C-reactive protein (hs-CRP) to detect subclinical atherosclerosis in RA patients.
    METHODS: We performed a comparative cross-sectional study of 47 RA patients who were in remission with a control group of non-RA patients with a history of atypical chest pain in Sarawak General Hospital from November 2008 to February 2009. All patients underwent 64-slice MDCT, assessment of arterial stiffness using the SphygmoCor test and blood analysis for NT-proBNP and hsCRP.
    RESULTS: There were 94 patients in our study with a mean age of 50 +/- 8.8 years. The RA and control patients in each group were matched in terms of traditional CV risk factors. Our RA patients had a median disease duration of 3 years (IQR 5.5). MDCT showed evidence of CAD in nine (19.1%) RA patients and three (6.4%) control patients (P = 0.06). There was no significant association between pulse wave velocity (PWV) and presence of CAD in our RA group. There was no significant correlation between PWV with levels of proBNP or hsCRP in our RA patients.
    CONCLUSIONS: In our current pilot study with the limitation of small sample size, RA was not associated with an increased risk of CAD in our RA patients who were in remission. Larger studies of CAD in Asian RA patients are needed to confirm our current finding.

    Poh R, Muniandy S
    Southeast Asian J. Trop. Med. Public Health, 2010 Sep;41(5):1231-46.
    PMID: 21073045
    The role of paraoxonase 1 in cardiovascular disease complications in type 2 diabetes mellitus is not fully understood. We studied paraoxonase activity towards paraoxon in 188 non-diabetic and 140 diabetic subjects using general linear models and univariate analysis. Adjusting for age revealed a reduction in activity towards paraoxon was associated with a significant increase in risk (p = 0.023) for cardiovascular disease complications in diabetic patients. Multivariate analysis of two plasma measures of paraoxonase activity using paraoxon and diazoxon also showed reduced paraoxonase activity towards paraoxon was associated with a significant increase in risk (p = 0.045) for cardiovascular disease complications in diabetic patients. These analyses showed that a reduced paraoxonase activity towards paraoxon was associated with ethnicity. Based on multivariate analysis, subjects of Malay ethnic origin have significantly higher than expected activity (p = 0.008, compared to Indians), towards paraoxon than subjects of Chinese origin who in turn had higher than expected paraoxonase activity (p = 0.028, compared to Indians) Indian subjects.

  10. Fulltext Diagnostic value of anti-modified citrullinated vimentin in rheumatoid arthritis
    Maraina CH, Nurdayana AK, Rusni D, Azwany Y
    Int J Rheum Dis, 2010 Oct;13(4):335-9.
    PMID: 21199468 DOI: 10.1111/j.1756-185X.2010.01552.x
    BACKGROUND: Rheumatoid factors (RF) are currently used in the diagnosis of rheumatoid arthritis (RA). Several other autoantibodies found in RA are directed to epitopes in citrullinated proteins such as anti-cyclic citrullinated and recently anti-modified citrullinated vimentin (MCV).
    OBJECTIVE: In this study we determined the sensitivity and specificity of anti-MCV in comparison with anti-cyclic citrullinated peptide (CCP) antibodies and RF in RA patients and in a control group using the American College of Rheumatology (ACR) criteria as the gold standard.
    MATERIALS AND METHODS: A cross sectional study was conducted from January to December 2008 on 100 patients with RA and 153 patients with arthritis or arthralgia but not fulfilling ACR criteria for RA. Serum from each subject was tested for anti-MCV, anti-CCP antibodies and immunoglobulin G (IgG) RF by enzyme-linked immunosorbent assay. Sensitivity and specificity of the tests were evaluated using the ACR criteria as the gold standard.
    RESULTS: The sensitivity of RF was 85% with 74.5% specificity. For anti-CCP antibodies the sensitivity was 71% and the specificity was 94.8%. The sensitivity of anti-MCV antibodies was 80% with 59.5% specificity. The area under the curve for RF was 0.759, for anti-CCP antibodies was 0.866 and for anti-MCV antibodies was 0.681, while for at least one positive test it was 0.691.
    CONCLUSION: Anti-CCP antibodies have higher diagnostic specificity and positive predictive value than RF and anti-MCV antibodies. RF has the highest sensitivity when compared to anti-CCP and anti-MCV antibodies. Thus anti-MCV antibody is not a better marker when compared to RF or anti-MCV antibody in the diagnosis of RA patients.

  11. Neonatal intrahepatic cholestasis associated with citrin deficiency (NICCD): a case series of 11 Malaysian patients
    Chew HB, Ngu LH, Zabedah MY, Keng WT, Balasubramaniam S, Hanifah MJ, et al.
    J Inherit Metab Dis, 2010 Dec;33 Suppl 3:S489-95.
    PMID: 21161389 DOI: 10.1007/s10545-010-9248-6
    Citrin deficiency, aetiologically linked to mutations of SLC25A13 gene, has two clinical phenotypes, namely adult-onset type II citrullinaemia (CTLN2) and neonatal/infantile intrahepatic cholestasis, caused by citrin deficiency (NICCD). Malaysian patients with NICCD, especially of Malay and East Malaysian indigenous descent, have never been reported in the literature. We present the clinical features, biochemical findings and results of molecular analysis in 11 Malaysian children with NICCD. In this case series, all patients manifested prolonged cholestatic jaundice and elevated citrulline levels. The other more variable features included failure to thrive, bleeding diathesis, hypoproteinaemia, abnormal liver enzymes, prolonged coagulation profile, hyperammonaemia, hypergalactosaemia, multiple aminoacidaemia, elevated α-feto protein and urinary orotic acid as well as liver biopsies showing hepatitis and steatosis. DNA analysis of SLC25A13 revealed combinations of 851del4(Ex9), IVS16ins3kb and 1638ins23. Most of our patients recovered completely by the age of 22 months. However, one patient had ongoing symptoms at the time of reporting and one had died of liver failure. Since a small percentage of children with NICCD will develop CTLN2 and the mechanisms leading to this is yet to be defined, ongoing health surveillance into adulthood is essential.

    Hypertensive disorders in pregnancy contributes to about 12% of maternal deaths in Malaysia and similarly worldwide. Early detection and adequate management are preventable strategies. Biochemical markers of abnormal angiogenesis would be more specific in early detection than routine blood pressure and proteinuria measurements. The aim of this study was to estimate maternal plasma PlGF and sFlt-1 levels in pregnant women with gestational hypertension at three intervals of pregnancy and correlate these biomarker levels with placental morphometry.

  13. Fulltext Histopathology and biochemistry analysis of the interaction between sunitinib and paracetamol in mice
    Lim AY, Segarra I, Chakravarthi S, Akram S, Judson JP
    BMC Pharmacol., 2010;10:14.
    PMID: 20950441 DOI: 10.1186/1471-2210-10-14
    BACKGROUND: Sunitinib, a tyrosine kinase inhibitor to treat GIST and mRCC may interact with paracetamol as both undergo P450 mediated biotransformation and P-glycoprotein transport. This study evaluates the effects of sunitinib-paracetamol coadministration on liver and renal function biomarkers and liver, kidney, brain, heart and spleen histopathology. ICR male mice (n = 6 per group/dose) were administered saline (group-A) or paracetamol 500 mg/kg IP (group-B), or sunitinib at 25, 50, 80, 100, 140 mg/kg PO (group-C) or coadministered sunitinib at 25, 50, 80, 100, 140 mg/kg PO and paracetamol IP at fixed dose 500 mg/kg (group-D). Paracetamol was administered 15 min before sunitinib. Mice were sacrificed 4 h post sunitinib administration.
    RESULTS: Group-A serum ALT and AST levels were 14.29 ± 2.31 U/L and 160.37 ± 24.74 U/L respectively and increased to 249.6 ± 222.7 U/L and 377.1 ± 173.6 U/L respectively in group-B; group-C ALT and AST ranged 36.75-75.02 U/L and 204.4-290.3 U/L respectively. After paracetamol coadministration with low sunitinib doses (group-D), ALT and AST concentrations ranged 182.79-221.03 U/L and 259.7-264.4 U/L respectively, lower than group-B. Paracetamol coadministration with high sunitinib doses showed higher ALT and AST values (range 269.6-349.2 U/L and 430.2-540.3 U/L respectively), p < 0.05. Hepatic histopathology showed vascular congestion in group-B; mild congestion in group-C (but lesser than in group-B and D). In group-D, at low doses of sunitinib, lesser damage than in group-B occurred but larger changes including congestion were observed at high sunitinib doses. BUN levels were higher (p < 0.05) for group-B (33.81 ± 5.68 mg/dL) and group-D (range 35.01 ± 6.95 U/L to 52.85 ± 12.53 U/L) compared to group-A (15.60 ± 2.17 mg/dL) and group-C (range 17.50 ± 1.25 U/L to 26.68 ± 6.05 U/L). Creatinine remained unchanged. Renal congestion and necrosis was lower in group-C than group-B but was higher in group-D (p > 0.05). Mild cardiotoxicity occurred in groups B, C and D. Brain vascular congestion occurred at high doses of sunitinib administered alone or with paracetamol. Hepatic and renal biomarkers correlated with histopathology signs.
    CONCLUSIONS: Paracetamol and sunitinib coadministration may lead to dose dependent outcomes exhibiting mild hepatoprotective effect or increased hepatotoxicity. Sunitinib at high doses show renal, cardiac and brain toxicity. Liver and renal function monitoring is recommended.

  18. Combined use of wild-type HBV precore and high serum iron marker as a potential tool for the prediction of cirrhosis in chronic hepatitis B infection
    Chook JB, Ngeow YF, Yap SF, Tan TC, Mohamed R
    J Med Virol, 2011 Apr;83(4):594-601.
    PMID: 21328372 DOI: 10.1002/jmv.22016
    Hepatitis B virus (HBV) and high liver iron deposits have both been associated with the development of cirrhosis. Among HBV factors, genotype and mutations in the basal core promoter (BCP) and precore regions have been most frequently studied but the evidence for a positive association with cirrhosis has been inconsistent. In this study, sera from persons with chronic HBV infection with and without cirrhosis were used for whole HBV genome analysis and for the estimation of serum iron marker (serum iron or ferritin) levels. Single codon analysis showed that the precore wild-type, TGG (nt 1,895-1,897), gave the highest accuracy (77.5%) for the identification of cirrhosis compared to other codons. When TGG was analyzed together with the precore start codon wild-type, ATG (nt 1,814-1,816), the accuracy was improved to 80.0% (odds ratio=35.29; 95% confidence interval=3.87-321.93; Phi=0.629; P<0.001). When the serum iron marker was included for analysis, it was clear that a combination of a precore wild-type and high serum iron marker gave a better accuracy (90.0%) (odds ratio=107.67; 95% confidence interval=10.21-1,135.59; Phi=0.804; P<0.001) for the identification of cirrhosis than either biomarker alone. It appeared that a combined use of both these biomarkers might help to predict the development of cirrhosis in a person with chronic HBV infection, but longitudinal studies are required to test this hypothesis.

    Jothy SL, Zakaria Z, Chen Y, Lau YL, Latha LY, Sasidharan S
    Molecules, 2011 Jun 23;16(6):5268-82.
    PMID: 21701437 DOI: 10.3390/molecules16065268
    BACKGROUND AND OBJECTIVE: Cassia fistula is widely used in traditional medicine to treat various types of ailments. The evaluation of toxic properties of C. fistula is crucial when considering public health protection because exposure to plant extracts can result in undesirable effects on consumers. Hence, in this study the acute oral toxicity of C. fistula seeds extract was investigated in mice.

    RESULTS: Oral administration of crude extract at the highest dose of 5000 mg/kg resulted in no mortalities or evidence of adverse effects, implying that C. fistula in nontoxic. Throughout 14 days of the treatment no changes in behavioural pattern, clinical sign and body weight of mice in both control and treatment groups. Also there were no any significant elevations observed in the biochemical analysis of the blood serum. Further, histopathological examination revealed normal architecture and no significant adverse effects observed on the kidney, heart, liver, lung and spleen.

    CONCLUSIONS: Overall, the results suggest that, the oral administration of C. fistula methanolic seeds extract did not produce any significant toxic effect in mice. Hence, the extract can be utilized for pharmaceutical formulations.
