HBeAG and anti-HBe in the Malaysian population and in Malaysian prisoners

Ton SH, Lopez CG, Noriah R

Southeast Asian J Trop Med Public Health, 1983 Jun;14(2):252-4.
PMID: 6635764

The incidence of HBsAg in random blood donors was found to be twice that of the prisoner population. The anti-HBe however, was about twice that in the prisoners when compared with the random blood donors. Both the random blood donors and the prisoners had similar incidence of HBeAg. The percentage frequency of HBsAg positivity with anti-HBe positivity was also similar in both groups. The 18 normal non-blood donors did not have HBsAg, HBeAg or anti-HBe.

Fulltext Digoxin toxicity: clinical and laboratory assessment

Ong HT, Ch'ng SL, Masduki A, Chandrasekharan N

Med J Malaysia, 1989 Dec;44(4):296-301.
PMID: 2520037

A prospective study to correlate clinical digoxin toxicity with serum digoxin levels was carried out in 67 patients of whom 24 were clinically toxic and 43 were asymptomatic. The patients were clinically diagnosed to be toxic based on typical cardiac arrhythmias (n = 11) or non-cardiac symptoms (n = 13). Blood samples were collected at least six hours after the last digoxin dose and the sera assayed for digoxin using a radioimmunoassay method. The mean serum digoxin level in the toxic group (x1 = 2.09 +/- 1.28 ng/ml) was significantly higher than in the non-toxic group (x2 = 1.20 +/- 0.75 ng/ml), p less than 0.01. All the non-toxic patients had serum digoxin levels below 3 ng/ml. However, there was a considerable overlap of serum digoxin levels between the two groups of patients. Serum level cannot be the sole criterion in diagnosing digoxin toxicity. Nevertheless, raised serum digoxin levels especially above 3 ng/ml, in the presence of suggestive clinical features is strongly suggestive of toxicity.

Heat-labile serum inhibitor of anti-phospholipid antibody binding in ELISA

Cheng HM, Phuah EB

Immunol Lett, 1989 Oct;22(4):263-6.
PMID: 2628284

Normal human sera (NHS), heat-inactivated at 56 degrees C for 30 min, demonstrated positive ELISA reactions for anti-cardiolipin (aCL) antibodies. The heat-induced reactivity in ELISA was inhibitable by the cardiolipin antigen and was abolished by prior IgG depletion of the heated NHS with a protein A preparation. The heat-potentiated aCL also cross-reacted selectively with phosphatidic acid and phosphatidylserine, but not with phosphatidylcholine or phosphatidylethanolamine.

Experimental infection of the leaf-monkey, Presbytis cristata, with subperiodic Brugia malayi

Mak JW, Choong MF, Suresh K, Lam PL

Parasitol Res, 1990;76(8):689-91.
PMID: 2251244

Presbytis cristata monkeys infected through the inoculation of between 200 and 400 subperiodic Brugia malayi infective larvae (L3) in the right thigh, in both thighs or in the dorsum of the right foot were followed up for varying periods of up to about 8 months after infection. All 148 inoculated animals became patent, with mean prepatent periods being between 66 and 76 days. In animals injected in the thigh, the patterns of microfilaraemia were similar, there being a rapid rise in the geometric mean counts (GMCs) of microfilariae during the first 10-12 weeks of patency, which then plateaued at levels of greater than 1000/ml. Adult worm recovery, expressed as the percentage of the infective dose, was significantly higher in animals injected with 100 L3 in each thigh, being 9.4% as compared with 2.8%-4.8% in other groups. It is therefore recommended that animals should be injected with 100 L3 in each thigh and that the testing of potential filaricides in this model be carried out during the phase of rapid increase in microfilaraemia to ensure that any microfilaricidal effect can easily be detected.

Evaluation of the whole blood lymphocyte transformation assay for scrub typhus exposure: adaptability to field sample collection

Lim TS, LaBarre DD, Lewis GE

Jpn. J. Med. Sci. Biol., 1988 Apr;41(2):57-68.
PMID: 3149355 DOI: 10.7883/yoken1952.41.57

The optimal conditions for the determination of exposure to scrub typhus by the whole blood lymphocyte transformation assay was 7 days culture of 10% blood in RPMI 1640 medium supplemented with 10% human AB-negative serum and L-glutamine with 50-200 micrograms protein/ml of Karp, Kato, or Gilliam strain membrane antigen. A simple exponentially decaying linear model shows the decrease in lymphocyte viability, the ability of sensitized cells to be stimulated with PHA mitogen, and the corresponding decrease in stimulation by scrub typhus antigens with increasing time of preincubation on ice. The lower limit of stimulation index for the detection of scrub typhus by whole blood lymphocyte transformation assay was 4.0 with a type I error of 1%.

Fulltext Gestational diabetes: what size the problem?

Wang KW, Balakrishnan V, Liauw PC, Chua EK, Vengadasalam D, Tan YT

Singapore Med J, 1988 Feb;29(1):53-5.
PMID: 3406769

Diabetes mellitus is a common chronic disease in Singapore. Its occurrence in pregnant women was 1.3% in a previous report. In a survey of 145 consecutive pregnant women registered at Alexandra Hospital the incidence of gestational diabetes was 13.1% when a total screen with 75 gm oral glucose challenge was used. The mean age of this sample was 27 years and the mean gestation at screening 33 weeks. There was an excess of Malay and Indian patients. Fifty percent had traditional risk factors tor gestational diabetes. Whether this higher incidence is a result of more stringent screening and/or increased occurrence remains to be confirmed.

Fulltext Lumbar sympathectomy techniques for critical lower limb ischaemia due to non-reconstructable peripheral arterial disease

Karanth VK, Karanth TK, Karanth L

Cochrane Database Syst Rev, 2016 12 13;12:CD011519.
PMID: 27959471 DOI: 10.1002/14651858.CD011519.pub2

BACKGROUND: Critical lower limb ischaemia (CLI) is a manifestation of peripheral arterial disease (PAD) that is seen in patients with typical chronic ischaemic rest pain or patients with ischaemic skin lesions - ulcers or gangrene - for longer than 2 weeks. Critical lower limb ischaemia is the most severe form of PAD, and interventions to improve arterial perfusion become necessary. Although surgical bypass has been the gold standard for revascularisation, the extent or the site of disease may be such that the artery cannot be reconstructed or bypassed. These patients require other modalities of treatment, for example, vasodilatation by drugs or lumbar sympathectomy to relieve pain at rest and to avoid amputations. A systematic review of randomised controlled trials is required to evaluate the effects of lumbar sympathectomy in treating patients with CLI due to non-reconstructable PAD.
OBJECTIVES: The objective of this review is to assess the effects of lumbar sympathectomy by open, laparoscopic and percutaneous methods compared with no treatment or compared with any other method of lumbar sympathectomy in patients with CLI due to non-reconstructable PAD.
SEARCH METHODS: The Cochrane Vascular Information Specialist (CIS) searched the Specialised Register (January 2016) and the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 12). In addition, the CIS searched clinical trials databases for details of ongoing and unpublished studies.
SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing any of the treatment modalities of lumbar sympathectomy, such as open, laparoscopic and chemical percutaneous methods, with no treatment or with any other method of lumbar sympathectomy for CLI due to non-reconstructable PAD were eligible. To decrease the bias of including participants that may be incorrectly diagnosed with CLI, review authors defined CLI as persistently recurring ischaemic rest pain requiring regular analgesia for more than two weeks, or ulceration or gangrene of the foot or toes, attributable to objectively proven arterial occlusive disease by measurement of ankle pressure of < 50 mmHg or toe pressure < 30 mmHg. We defined non-reconstructable PAD as a resting ankle brachial index (ABI) < 0.9 when no reasonable open surgical or endovascular revascularisation treatment option is available, as determined by individual trial vascular specialists.
DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies identified for potential inclusion in the review. We planned to conduct data collection and analysis in accordance with the Cochrane Handbook for Systematic Review of Interventions.
MAIN RESULTS: We identified no studies that met the predefined inclusion criteria. To decrease the bias of including participants who may be incorrectly diagnosed with CLI, we based our inclusion criteria on objective tests, as described above. The randomised trials identified by the literature search were performed before such objective criteria for selection were applied and therefore were not eligible for inclusion in the review.
AUTHORS' CONCLUSIONS: We identified no RCTs assessing effects of lumbar sympathectomy by open, laparoscopic and percutaneous methods compared with no treatment or compared with any other method of lumbar sympathectomy in patients with CLI due to non-reconstructable PAD. High-quality studies are needed.

QbD-Driven Development and Validation of Liquid Chromatography Tandem Mass Spectrometric Method for the Quantitation of Sildenafil in Human Plasma

Hasnain MS, Ansari SA, Rao S, Tabish M, Singh M, Abdullah MS, et al.

J Chromatogr Sci, 2017 Jul 01;55(6):587-594.
PMID: 28335023 DOI: 10.1093/chromsci/bmx010

The present work was employing the Quality by Design approach for the development and validation of a LC-MS-MS method to support the clinical advancement in determination of sildenafil in human plasma using lorazepam as an internal standard. Sample preparation involved solid phase extraction and calibration range observed between 3 and 1,700 ng/mL. The method was systematically optimized by employing Box-Behnken design and used mobile phase flow rate, pH and composition of mobile phase as the critical factors, and assessing the design for retention time and peak area as the responses. A substantial decrease in the variability associated with the method variables was shown in optimization studies and confirmed enhanced method robustness. The present studies revealed that developed method achieves all the regulatory requirements for linearity, accuracy, precision, selectivity, sensitivity and stability for the determination of sildenafil in human plasma. There was not any significant change in the stability of the drug shown by stability studies, performed in human plasma through freeze-thaw cycles, bench-top stability, short-term stability, long-term stability and auto sampler stability. In short, this method shows satisfactory results for the analysis of sildenafil in human plasma and possesses high degree of utility in pharmacokinetic and bioequivalence studies.

Left ventricular flow propagation velocity measurement: Is it cast in stone?

Chan BT, Yeoh HK, Liew YM, Aziz YFA, Sridhar GS, Hamilton-Craig C, et al.

Med Biol Eng Comput, 2017 Oct;55(10):1883-1893.
PMID: 28321684 DOI: 10.1007/s11517-017-1639-5

This study aims to investigate the measurement of left ventricular flow propagation velocity, V p, using phase contrast magnetic resonance imaging and to assess the discrepancies resulting from inflow jet direction and individual left ventricular size. Three V p measuring techniques, namely non-adaptive (NA), adaptive positions (AP) and adaptive vectors (AV) method, were suggested and compared. We performed the comparison on nine healthy volunteers and nine post-infarct patients at four measurement positions, respectively, at one-third, one-half, two-thirds and the conventional 4 cm distances from the mitral valve leaflet into the left ventricle. We found that the V p measurement was affected by both the inflow jet direction and measurement positions. Both NA and AP methods overestimated V p, especially in dilated left ventricles, while the AV method showed the strongest correlation with the isovolumic relaxation myocardial strain rate (r = 0.53, p

Studies on the Malayan forest rat filaria, Breinlia booliati: periodicity and microfilaraemic patterns during the course of infection

Yap EH, Ho BC, Singh M, Kang KL, Lim BL

J Helminthol, 1975 Dec;49(4):263-9.
PMID: 1206216

Breinlia booliati exhibited nocturnal subperiodicity in its natural host, Rattus sabanus in contrast to experimentally infected laboratory-reared albine rats which showed irregular fluctuations of microfilariae throughout the 24 hour cycle. All the infected albino rats showed a prepatent period between 11-14 weeks postinoculation. Three patterns of microfilaraemia were discerned during the course of infection 38/49 rats displayed a single peak, 4/49 displayed 2 peaks about 12-15 weeks apart and 7/49 showed a sustained high plateau-like pattern of microfilaraemia. Cortisone had no effect on microfilarial levels when administered to rats near postpatency and some at postpatency.

Background: In Malaysia, the prevalence of hypertension amongst adults aged 30 years and above has increased from 32.9% in 1996 to 40.5% in 2004 and to 42.6% in 2006. Information on the prevalence of hypertension among adolescents is lacking.
Objective: to determine the prevalence of hypertension among Malay secondary school students in Putrajaya.
Methods: A cross sectional study was carried out in Putrajaya, Malaysia. The sampling frame consisted of a list of all the 12 secondary schools in Putrajaya. Three schools were selected using table of random numbers. All Malay students aged 13 years old to 17 years old from the three selected school students were included in the study. Blood pressure was measured after the respondents had rested for at least 5 minutes using a standard mercury sphygmomanometer. Three blood pressure measurements were taken for each respondent. Systolic blood pressure [SBP] was defined as the average of three SBP readings and diastolic blood pressure [DBP] was defined as the average of three DBP readings. Data was analyzed using SPSS 18.
Results: The overall mean SBP and DBP were 108.9 mmHg and 63.2 mmHg respectively. The prevalence of pre-hypertension and hypertension among the male was 16.2% and 12.9% respectively as compared to 5.8% and 10.2% respectively in the females. The overall prevalence of prehypertension and hypertension was 11.1% and 11.6% respectively. The prevalence increased with age (p<0.05). There was a significant positive correlation between BMI and SBP (r = 0.52, r2 = 0.27, p= 0.001) and BMI and DBP (r = 0.38, r2 = 0.15, p= 0.001). The mean SBP was significantly higher in males (111.7 mmHg) as compared to 106 mmHg in females (p<0.001). The mean DBP in males (63.5 mmHg) was slightly higher as compared to 62.9 mmHg in females but the difference was not significant.
Conclusions: Prevalence of hypertension and pre-hypertension is high. There is an urgent need for implementation of a comprehensive CVD prevention program and routine blood pressure measurements should be taken in school children to improve the detection, prevention and treatment of hypertension

Night work and rotating shift work are found to be detrimental to the health of workers. A cross sectional analytical study was conducted among the employees of a public medical centre in Kuala Lumpur. A total of 380 employees participated in the health screening and questionnaire survey. The majority of the respondents were Malays, females, and with mean age of 49 years old. The shift workers persistently had higher but non-significant proportions of being overweight/obesity and unhealthy clinical indicators such as systolic and diastolic blood pressure, fasting blood glucose and lipid profile except waist circumferences and HDL-cholesterol. There were also slightly more shift workers diagnosed with diabetes mellitus, hypertension or coronary heart disease (p>0.05). Although the present study could not provide established evidence for a relationship between shift work and cardiovascular risks, this could serve as a pilot study for future studies in this area.

Int J Public Health Res, 2011;1(2):72-78.
MyJurnal

Introduction Hepatitis C Virus (HCV) recently was identified as a major cause of post transfusion hepatitis world wide. To evaluate the role of blood transfusion on the prevalence of HCV infection, by testing antibody and RNA as well as the genotypes of HCV .Also to detect if Blood transfusion acts as unconfounding risk factor for HCV infection.
Methods Sera from 3491 pregnant women were investigated for the presence of HCV antibodies (anti-HCV) by using third generation enzyme immunoassay (EIA-3) as screening test, followed by immunoblot assay (Lia Tek-III). In addition 94 sera of studied women were subjected to molecular analysis (at laboratories of Sorin BioMedica - Italy) for the detection of viral RNA and genotypes of HCV. Using RT-PCR & DNA Enzyme immunoassay (DEIA) method.
Results Our study revealed, that seroprevalence rate of HCV specific Ab & RNA were significantly higher (16.32 %, 80% respectively) among women with a history of blood transfusion, compared to those (2.53%, 56.5%) with no such history P=0.0001, P=0.01. And there is a significant direct linear correlation between number of blood transfused and the seropositive rate of anti-HCV (r=0.7, p=0.046). Based on multivariate analysis, interestingly, this study confirmed that, blood transfusion significantly acting as unconfounding risk factor for acquiring HCV infection (Adjusted OR=1.938,95% C.I=1.646-2.28). And the risk of exposure is increases with increased number of blood transfused. Although, we found no significant association between, HCV genotypic distribution and history of blood transfusion. However, high proportion of women with a history of blood transfusion were harboring HCV genotype -4 or 1b, 50%,40%, resepctively.
Conclusions Our study shows, evidence that, blood transfusion acts as unconfounding risk factor for acquiring and in a mode of transmission of HCV infection. Therefore strict screening of blood donor for HCV-Abs and / or RNA is highly recommended.

Current issues in the management of thalassaemia

Rahman Jamal

Malaysian Journal of Child Health, 1998;10(1):1-8.
MyJurnal

The thalassaemias are the commonest single gene disorders amongst the inherited diseases. In Malaysia, there are an estimated 2200 transfusion dependent thalassaemia patients. With a carrier rate of 3-5%, 120-340 new cases of thalassaemia are expected to be born each year. The reference treatments for these patients are regular blood transfusions and iron chelation therapy. With optimal management, these patients are able to survive into the third or fourth decade of life and most importantly avoid the complications related to transfusions and iron overload. The use of desferal locally is still limited to only those who can afford i.e. about 30% of the cases. Treatment for some of the complications such as hepatitis C, diabetes mellitus, growth impairment and pubertal delay, are now available. Curative treatment approaches like bone marrow transplantation have now become standard treatment for eligible cases whilst cord blood transplantation may yet offer hope for those who are without compatible sibling donors. Research on globin gene therapy looks very promising but will probably take some time to deliver. Hb F switching is a very novel idea but so far the results are mainly anecdotal. Finally, the strive for optimal management of thalassaemia must come hand in hand with a prevention programme to achieve a reduction of new cases.
