    PMID: 22331687
    OBJECTIVE: To study the validity of the visual clinical assessment of weight relative to length and length relative to age as compared to the World Health Organization (WHO) 2006 standard and National Center for Health Statistics (NCHS) 1977 reference in asssessing the physical growth of children younger than 1 year.

    MATERIALS AND METHODS: A prospective cohort study was carried out among 684 infants attending goverment health clinics in 2 states in Malaysia. Body weight, length, and clinical assessment were measured on the same day for 9 visits, scheduled every month until 6 months of age and every 2 months until 12 months of age. All of the 3 z-scores for weight for age (WAZ), length for age (HAZ), and weight for length (WHZ) were calculated using WHO Anthro for Personal Computers software.

    RESULTS: The average sensitivity and specificity for the visual clinical assessment for the detection of thinness were higher using the WHO 2006 standard as compared with using NCHS 1977. However, the overall sensitivity of the visual clinical assessment for the detection of thin and lean children was lower from 1 month of age until a year as compared with the WHO 2006 standard and NCHS 1977 reference. The positive predictive value (PPV) for the visual clinical assessment versus the WHO 2006 standard was almost doubled as compared with the PPV of visual clinical assessment versus the NCHS 1977 reference. The overall average sensitivity, specificity, PPV, and negative predictive value for the detection of stunting was higher for visual clinical assessment versus the WHO 2006 standard as compared with visual clinical assessment versus the NCHS 1977 reference.

    CONCLUSION: The sensitivity and specificity of visual clinical assessment for the detection of wasting and stunting among infants are better for the WHO 2006 standard than the NCHS 1977 reference.

  2. Fulltext HLA-DQ A1, -DQB1 and -DRB1 gene polymorphism--in Malay type 1 diabetes mellitus patients and their use for risk prediction
    Rohana AG, Loh KC, Tin SK, Soh CH, Nazaimoon WM, Fong KY, et al.
    Med J Malaysia, 2011 Jun;66(2):133-7.
    PMID: 22106694
    HLA-DQA1, -DQB1, and -DRB1 gene polymorphism were analyzed to study type 1 DM susceptibility in Malay patients from Southeast Asia (Malaysia and Singapore). Patients showed significant increases in the occurrence of DQA1*0501 (50.7% vs. 20.4%; RR = 3.97; Pc < 0.01), DQB1*0201 (48% vs. 19.1%; RR = 3.86; Pc < 0.05), and DRB1*0301 (38.7 vs. 6.8%; RR = 8.36; 95% Pc < 0.05). Conversely, significant decreases were noted in the occurrence of DQA1*0601 (14.7% vs. 35.2%; RR = 0.33; Pc = 0.008) and DQB1*0601 (4% vs. 23.5%; RR = 0.16; Pc < 0.05) in type 1 DM patients. Using a logistic regression model, we derived a risk prediction model for type 1 DM in our indigenous Malay population based on the identified HLA genotypes. The RR for type 1 DM increases by a factor of 5.68 for every unit increase in the number of DRB1*0301 allele (P < 0.001), and decreases by a factor of 0.18 per unit increase in the number of DQB1*0601 allele (P < 0.001). After adjusting for these two HLA genotypes, DQA1*0501, DQB1*0201 and DQA1*0601 were not statistically significant as risk predictors. The lower incidence of type 1 DM in the Malay population may be contributed by the genotypic combinations of DR and DQ genes as well as the linkage disequilibria between susceptible and protective alleles.

  3. Ultrasonic plaque echolucency and emboli signals predict stroke in asymptomatic carotid stenosis
    Topakian R, King A, Kwon SU, Schaafsma A, Shipley M, Markus HS, et al.
    Neurology, 2011 Aug 23;77(8):751-8.
    PMID: 21849657 DOI: 10.1212/WNL.0b013e31822b00a6
    Better methods are required to identify patients with asymptomatic carotid stenosis (ACS) at risk of future stroke. Two potential markers of high risk are echolucent plaque morphology on carotid ultrasound and embolic signals (ES) in the ipsilateral middle cerebral artery on transcranial Doppler ultrasound (TCD). We explored the predictive value of a score based on these 2 measures in the prospective, observational, international multicenter Asymptomatic Carotid Emboli Study.

  4. Clinical predictors of non-diabetic renal disease and role of renal biopsy in diabetic patients with renal involvement: a single centre review
    Chong YB, Keng TC, Tan LP, Ng KP, Kong WY, Wong CM, et al.
    Ren Fail, 2012;34(3):323-8.
    PMID: 22250665 DOI: 10.3109/0886022X.2011.647302
    BACKGROUND:
    Type 2 diabetes mellitus (T2DM) is reportedly the leading cause of end-stage renal disease (ESRD) worldwide. However, non-diabetic renal diseases (NDRD) are not uncommon among T2DM patients with renal involvement. Our study aimed to examine the prevalence of NDRD in T2DM and clinical markers for diabetic nephropathy (DN) and NDRD and to determine the role of renal biopsy in T2DM patients and its impact on clinical practice.

    METHODS:
    We conducted a retrospective analysis of T2DM patients in whom renal biopsies were performed from January 2004 to March 2008 (n = 110).

    RESULTS:
    Biopsy results were divided into three groups: group I/pure DN (62.7%), group II/isolated NDRD (18.2%), and group III/mixed lesions (19.1%). The causes of NDRD in decreasing order of frequency were acute interstitial nephritis, glomerulonephritides, hypertensive renal disease, and acute tubular necrosis. Significant clinical markers for DN are presence of diabetic retinopathy and longer duration of diabetes. For NDRD, useful clinical markers include the presence of acute renal failure and microscopic hematuria. In the DN subgroup, Indians had significantly shorter duration of diabetes on biopsy compared with Malays and Chinese.

    CONCLUSIONS:
    NDRD is prevalent in T2DM patients, and given its potentially treatable nature, renal biopsy should be considered in T2DM patients with nephropathy, especially in those with atypical features.

    Tan PC, King AS, Omar SZ
    J Obstet Gynaecol Res, 2012 Jan;38(1):145-53.
    PMID: 21955280 DOI: 10.1111/j.1447-0756.2011.01652.x
    AIM: The aim of this study was to evaluate urine microscopy, dipstick analysis and urinary symptoms in screening for urinary tract infection (UTI) in hyperemesis gravidarum (HG).
    MATERIALS AND METHODS:   A prospective cross-sectional study was performed on women at first hospitalization for HG. A clean-catch mid-stream urine sample from each recruit was sent for microscopy (for bacteria, leucocytes and erythrocytes), dipstick analysis (for leukocyte esterase, nitrites, protein and hemoglobin) and microbiological culture. The presence of current urinary symptoms was elicited by questionnaire. UTI is defined as at least 10(5) colony-forming units/mL of a single uropathogen on culture. Screening test parameters were analyzed against UTI.
    RESULTS: UTI was diagnosed in 15/292 subjects (5.1%). Receiver-operator characteristic curve analysis of microscopic urine leucocytes revealed area under the curve=0.64, 95% confidence interval (CI) 0.5-0.79, P=0.063 and erythrocytes area under the curve=0.53, 95%CI 0.39-0.67, P=0.67 for UTI indicating the limited screening utility of these parameters. Microscopic bacteriuria (likelihood ratio [LR] 1.1, 95%CI 0.7-1.5) and urine dipstick leukocyte esterase (LR 1.4, 95%CI 1.1-1.8), nitrites (LR 2.3, 95%CI 0.3-17.2), protein (LR 1.0, 95%CI 0.7-1.6) and hemoglobin (LR 0.8, 95%CI 0.4-1.5) were not useful screening tests for UTI in HG. Elicited symptoms were also not predictive of UTI.
    CONCLUSION: Urine microscopy, dipstick analysis and urinary symptoms were not useful in screening for UTI in HG. UTI should be established by urine culture in HG before starting antibiotic treatment.

    Norizan A, Shamsuddin K
    J Intellect Disabil Res, 2010 Nov;54(11):992-1003.
    PMID: 20868445 DOI: 10.1111/j.1365-2788.2010.01324.x
    Having children with intellectual disability can be stressful for most parents. Currently there are very few studies focusing on parenting stress among mothers of children with Down syndrome (DS) in Asia. The present study examined the level of parenting stress experienced by Malaysian mothers of children with DS and evaluated the child and maternal factors that contributed to parenting stress based on Hill's ABC-X Model (Hill 1949).

  7. Role of phIGFBP-1 and ultrasound cervical length in predicting pre-term labour
    Azlin MI, Bang HK, An LJ, Mohamad SN, Mansor NA, Yee BS, et al.
    J Obstet Gynaecol, 2010;30(5):456-9.
    PMID: 20604646 DOI: 10.3109/01443615.2010.489162
    This prospective observational study was to evaluate the efficacy of combining phosphorylated insulin-like growth factor binding protein-1 (phIGFBP-1) and transvaginal ultrasound cervical length (CL) compared with either indicator alone in predicting pre-term labour (PTL). Women with singleton pregnancy between 24 and 36 weeks' gestation with evidence of PTL were subjected to phIGFBP-1 and CL tests. Of the 51 women, five were tested positive (phIGFBP-1 positive and CL <2.5 cm) for combination of phIGFBP-1 and CL (four delivered within 1 week), whereas 46 tested negative, of which, only one delivered. A much higher negative predictivity (NP), positive predictivity (PP) and specificity (SP) in the combination test was seen compared with phIGFBP-1 or CL alone (NP: 97.8% vs 97.7% vs 97.1%; PP: 80.0% vs 51.1% and CL 23.5%; SP: 97.8% vs 93.5% vs 71.1%, respectively). The cervical os dilatation of 2 cm with combined positive test (p = 0.001) indicated a higher likelihood of PTL.

  8. Fulltext Assessing the impact of vomiting episodes on outcome after acetaminophen poisoning
    Zyoud SH, Awang R, Sulaiman SA, Al-Jabi SW
    Basic Clin Pharmacol Toxicol, 2010 Nov;107(5):887-92.
    PMID: 20456332 DOI: 10.1111/j.1742-7843.2010.00594.x
    Identifying indices of poor prognosis at first presentation after acetaminophen poisoning is the key to both improving clinical care and determining targets for intervention. This study intended to document the prevalence, clinical characteristics and predictors of vomiting and to investigate the relationship between episodes of vomiting at first hospital presentation and outcome in acetaminophen poisoning. This retrospective cohort study included patients who attended the emergency department and were admitted within 24 hr of acetaminophen ingestion. The study was conducted over a period of 5 years from 1 January 2004 to 31 December 2008. Parametric and non-parametric tests were used to test differences between groups depending on the normality of the data. SPSS 15 was used for data analysis. Data from 291 patients were included. Vomiting was present in 65.3% of patients with acetaminophen poisoning at the time of first presentation. Multiple logistic regression showed that significant risk factors for vomiting were present among patients who reported an ingested dose of acetaminophen ≥10 g (p < 0.001) and a latency time of more than 8 hr (p = 0.030). Overall, an increasing trend in prothrombin time (p = 0.03), serum bilirubin (p < 0.001), serum creatinine (p = 0.005), serum potassium (p < 0.001), length of hospital stay (p < 0.001) and the prevalence of patients who had a serum acetaminophen level above a 'possible toxicity' treatment line (p = 0.001) were associated with an increased number of episodes of vomiting. In conclusion, vomiting was common among patients with acetaminophen poisoning. This study suggests that an increase in episodes of vomiting at first presentation appears to be an important risk marker of subsequent nephrotoxicity and hepatotoxicity.

  9. 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.

  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. Fulltext A case-controlled validation study of a blood-based seven-gene biomarker panel for colorectal cancer in Malaysia
    Yip KT, Das PK, Suria D, Lim CR, Ng GH, Liew CC
    J Exp Clin Cancer Res, 2010;29:128.
    PMID: 20846378 DOI: 10.1186/1756-9966-29-128
    BACKGROUND: Colorectal cancer (CRC) screening is key to CRC prevention and mortality reduction, but patient compliance with CRC screening is low. We previously reported a blood-based test for CRC that utilizes a seven-gene panel of biomarkers. The test is currently utilized clinically in North America for CRC risk stratification in the average-risk North American population in order to improve screening compliance and to enhance clinical decision making.
    METHODS: In this study, conducted in Malaysia, we evaluated the seven-gene biomarker panel validated in a North American population using blood samples collected from local patients. The panel employs quantitative RT-PCR (qRT-PCR) to analyze gene expression of the seven biomarkers (ANXA3, CLEC4D, TNFAIP6, LMNB1, PRRG4, VNN1 and IL2RB) that are differentially expressed in CRC patients as compared with controls. Blood samples from 210 patients (99 CRC and 111 controls) were collected, and total blood RNA was isolated and subjected to quantitative RT-PCR and data analysis.
    RESULTS: The logistic regression analysis of seven-gene panel has an area under the curve (AUC) of 0.76 (95% confidence interval: 0.70 to 0.82), 77% specificity, 61% sensitivity and 70% accuracy, comparable to the data obtained from the North American investigation of the same biomarker panel.
    CONCLUSIONS: Our results independently confirm the results of the study conducted in North America and demonstrate the ability of the seven biomarker panel to discriminate CRC from controls in blood samples drawn from a Malaysian population.

  13. Pattern and predictors of soil-transmitted helminth reinfection among aboriginal schoolchildren in rural Peninsular Malaysia
    Hesham Al-Mekhlafi M, Surin J, Atiya AS, Ariffin WA, Mohammed Mahdy AK, Che Abdullah H
    Acta Trop, 2008 Aug;107(2):200-4.
    PMID: 18582430 DOI: 10.1016/j.actatropica.2008.05.022
    Data on soil-transmitted helminth (STH) infections and reinfection among Orang Asli (aborigine) schoolchildren and their nutritional and socioeconomic status were analyzed to investigate the pattern and the possible predictors of STH reinfection. In this longitudinal study, 120 (60 males and 60 females) Orang Asli primary schoolchildren aged 7-12 years and living in remote areas in Pos Betau, Kuala Lipis, Pahang were screened for the presence of STH using modified cellophane thick smear and Harada Mori techniques. The overall prevalence of ascariasis, trichuriasis and hookworm infections were 65.8, 97.5 and 10.8%, respectively. After complete deworming with a 3-day course of 400mg/daily of albendazole tablets, children were re-examined at 3 and 6 months from baseline. The reinfection rate, by one or more of STH species, at 3 months after deworming was high (49.5%) while 79.6% of the children were reinfected at 6 months after deworming. Logistic regression analyses showed that females, stunted children and those living in houses without toilets had significantly higher reinfection rates than others at 3 months (P<0.05). At 6 months, maternal employment status emerged as another predictor where children of working mothers had significantly higher reinfection rates (P=0.026). In conclusion, reinfection rate of STH is high and thus necessitates frequent and periodic deworming among children. Public health personnel need to re-look at the current control measures and identify innovative and integrated ways in order to reduce STH significantly in the rural communities.

  14. The 50-g glucose challenge test and pregnancy outcome in a multiethnic Asian population at high risk for gestational diabetes
    Tan PC, Ling LP, Omar SZ
    Int J Gynaecol Obstet, 2009 Apr;105(1):50-5.
    PMID: 19154997 DOI: 10.1016/j.ijgo.2008.11.038
    OBJECTIVE:
    To evaluate the 50-g glucose challenge test (GCT) on pregnancy outcome in a multiethnic Asian population at high risk for gestational diabetes (GDM).

    METHODS:
    GCT was positive if the 1-hour plasma glucose level was >or=7.2 mmol/L. GDM was diagnosed by a 75-g glucose tolerance test using WHO (1999) criteria. Of the 1368 women enrolled in the study, 892 were GCT negative, 308 were GCT false-positive, and 168 had GDM. Pregnancy outcomes were extracted from hospital records. Multivariable logistic regression analysis was performed with GCT negative women as the reference group.

    RESULTS:
    GCT false-positive status was associated with preterm birth (adjusted odds ratio [AOR] 2.1; 95% CI, 1.2-3.7) and postpartum hemorrhage (AOR 1.7; 95% CI, 1.0-2.7). GDM was associated with labor induction (AOR 5.0; 95% CI, 3.3-7.5), cesarean delivery (AOR 2.2; 95% CI, 1.6-3.2), postpartum hemorrhage (AOR 2.1; 95% CI, 1.2-3.7), and neonatal macrosomia (AOR 2.5; 95% CI, 1.0-6.0).

    CONCLUSION:
    GCT false-positive women had an increased likelihood of an adverse pregnancy outcome. The role and threshold of the GCT needs re-evaluation.

  15. Fulltext Does the pre-operative value of serum CA15-3 correlate with survival in breast cancer?
    Velaiutham S, Taib NA, Ng KL, Yoong BK, Yip CH
    Asian Pac J Cancer Prev, 2008 Jul-Sep;9(3):445-8.
    PMID: 18990019
    INTRODUCTION: CA15-3 is a well-known tumour marker for breast cancer. Currently it is not recommended for screening or diagnosis of breast cancer and its main application is in monitoring response to treatment in women with metastatic breast cancer. The aim of this study was to correlate serum CA15-3 at presentation with the stage of disease and overall survival in women with breast cancer in the University Malaya Medical Centre.

    METHODS: This is a retrospective study of 437 women who had CA15-3 levels determined at initial presentation of breast cancer to UMMC between Jan 1999 and Oct 2003.

    RESULTS: Of those patients who were adequately staged, CA15-3 was found to be elevated (defined as >51 U/ml) in 0% of Stage 1, 7.9% of Stage 2, 36.7% of Stage 3 and 68.6% of Stage 4 cases. In a subset of 331 patients with survival data, patients with normal CA15-3 had a 85% five year overall survival rate compared to 38% in their counterparts with elevation of the tumor marker. The level of elevation was also significantly related to survival; patients with values more than 200 U/ml exhibited only a 28% five year survival. The association of elevated CA15-3 at initial presentation with poor outcome was maintained over univariate and multivariate analyses.

    CONCLUSION: Estimation of CA15-3 at presentation of breast cancer is important as it is an independent prognostic indicator and may prompt the physician to investigate for metastases if elevated.

  16. Combination of SMN2 copy number and NAIP deletion predicts disease severity in spinal muscular atrophy
    Watihayati MS, Fatemeh H, Marini M, Atif AB, Zahiruddin WM, Sasongko TH, et al.
    Brain Dev, 2009 Jan;31(1):42-5.
    PMID: 18842367 DOI: 10.1016/j.braindev.2008.08.012
    Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder caused by mutations in the SMN1 gene. The SMN2 gene is highly homologous to SMN1 and has been reported to be correlated with severity of the disease. The clinical presentation of SMA varies from severe to mild, with three clinical subtypes (type I, type II, and type III) that are assigned according to age of onset and severity of the disease. Here, we aim to investigate the potential association between the number of copies of SMN2 and the deletion in the NAIP gene with the clinical severity of SMA in patients of Malaysian origin. Forty-two SMA patients (14 of type I, 20 type II, and 8 type III) carrying deletions of the SMN1 gene were enrolled in this study. SMN2 copy number was determined by fluorescence-based quantitative polymerase chain reaction assay. Twenty-nine percent of type I patients carried one copy of SMN2, while the remaining 71% carried two copies. Among the type II and type III SMA patients, 29% of cases carried two copies of the gene, while 71% carried three or four copies of SMN2. Deletion analysis of NAIP showed that 50% of type I SMA patients had a homozygous deletion of exon 5 of this gene and that only 10% of type II SMA cases carried a homozygous deletion, while all type III patients carried intact copies of the NAIP gene. We conclude that there exists a close relationship between SMN2 copy number and SMA disease severity, suggesting that the determination of SMN2 copy number may be a good predictor of SMA disease type. Furthermore, NAIP gene deletion was found to be associated with SMA severity. In conclusion, combining the analysis of deletion of NAIP with the assessment of SMN2 copy number increases the value of this tool in predicting the severity of SMA.

    PMID: 18376797 MyJurnal
    Hepatocellular carcinoma (HCC) is the most common primary liver cancer and its diagnosis on routine stains is usually straightforward, except in some cases where there may be difficulty in distinguishing HCCs from metastatic carcinomas (MC) and cholangiocarcinomas (CC). Hepatocyte Paraffin 1 antibody (Hep Par 1) is a new monoclonal antibody which reacts with normal and neoplastic hepatocytes, and this study aims to determine its specificity and sensitivity in distinguishing hepatocellular carcinoma (HCC) from cholangiocarcinoma (CC) and metastatic carcinomas (MC). Hep Par 1 antibody was applied to 28 cases of HCC, 22 cases of MC from varying sites and 8 CCs, and produced a strong, diffuse, granular, cytoplasmic staining of all benign hepatocytes. 23 out of 28 cases of HCC showed heterogeneously positive staining for Hep Par 1 irrespective of their degree of differentiation, while 2 out of 8 cases of cholangiocarcinoma were positive for Hep Par 1, and all 22 cases of metastatic carcinoma were negative. The sensitivity and specificity of Hep Par 1 for HCC was 82.1% and 93.3% respectively; whereby the antibody was noted to show occasional false positivity in cases of cholangiocarcinoma and non-neoplastic bowel mucosa, while its variable staining in HCC produced false negative results in some small biopsies. Thus, Hep Par 1 should be used in a panel with other antibodies to obtain useful information in distinguishing HCC from CC and MC.

    This study was done to determine the correlation between glucose monitoring by fasting blood glucose or 2 hours postprandial blood glucose with HbA1c and fructosamine in type 2 diabetic patients. A total of 82 patients from the Primary Care Clinic were enrolled in the study. Fasting blood was drawn for fasting plasma glucose (FPG), glycated haemoglobin (HbA1c) and fructosamine. Two hours after a standard breakfast, blood was again drawn for prandial plasma glucose (PPG). Both PPG and FPG significantly correlated with both HbA1c and fructosamine but PPG showed better correlation to HbA1c than FPG (r= 0.604 vs.0.575) whereas that of FPG and PPG were equally correlated to fructosamine (r= 0.566 vs. 0.551). In predicting good glycaemic control (HbA1c < 7.0%), the sensitivity, specificity and positive predictive value of PPG were 75.0%, 80.6% and 82.5% whereas FPG were 81.8%, 58.3% and 70.6% respectively. These results show that PPG correlated better than FPG to HbA1c and both equally correlated to fructosamine levels. Thus, PPG predicted overall glycaemic control better than FPG. Compared to HbA1c, fructosamine correlated least well with mean glucose profiles. Hence, using HbAlc in monitoring overall glycaemic control is better than fructosamine.

    PMID: 17014550
    Sepsis is characterized by an uncontrolled release of pro-inflammatory and anti-inflammatory mediators leading to immunoparalysis, cellular and humoral dysfunction, multiorgan dysfunction and death. This study evaluated the efficacy of high-volume haemofiltration (HVHF) compared with continuous venovenous haemofiltration (CVVH) in removing these inflammatory mediators. Clinical responses were assessed with the sequential organ failure assessment (SOFA) score.
