Abstract

Spektrum patologi klinik dari perlemakan hati non alkoholik (PHNA) terentang dari simple steatosis sampai non alkoholic steatohepatitis (NASH). Simple steatosis memiliki perjalanan klinik yang relatif jinak, namun NASH dapat berkembang ke sirosis dan karsinoma hepatoseluler. PHNA umumnya asimtomatik dan harus dicurigai pada pasien-pasien dengan obesitas abdominal dan diabetes melitus tipe 2. Peningkatan alanine aminotransferase (ALT) serum dan/atau gambaran perlemakan hati pada USG sering kali merupakan temuan pertama yang mengarahkan diagnosis ke PHNA. Diagnosis PHNA ditegakkan setelah menyingkirkan penyakit hati kronis yang lain; diagnosis definitif hanya dibuat dengan biopsi. Peningkatan ALT umumnya tidak melebihi 5 kali batas atas nilai normal. Adanya ikterus, bilirubinuria dan demam juga menyingkirkan diagnosis PHNA. Sebagian besar steatosis hepatik tidak berkembang menjadi fibrosis atau steato hepatitis, 30-40% akan menjadi fibrosis dalam periode 4 tahun dan +15% akan berkembang menjadi sirosis. Penatalaksanaan PHNA tidak ditargetkan pada hepar saja, melainkan harus holistik, berpusat pada perbaikan resistensi insulin dan gangguan metabolisme terkait, yang dimulai dengan modifikasi gaya hidup. Berat badan harus diturunkan secara bertahap.Vitamin E dan asam ursodeoksikolat diberikan karena dapat menurunkan ALT. Metformin dan/atau rosiglitazone dapat diberikan pada pasien tanpa diabetes yang nyata, karena obat-obat ini tidak menyebabkan hipoglikemia, dan dapat meningkatkan sensitivitas insulin. Perburukan fungsi hati juga harus dicegah dengan menghindari zat-zat hepatotoksik.

Abstract

The increased percentage of patients with HIV-TB coinfection leads to inevitable interactions between rifampicin and efavirenz. Efavirenz is a potent non-nucleoside reverse transcriptase inhibitor (NNRTI) for the treatment of HIV infection. The use of this drug combination with rifampicin causes problems in determination of the optimal dosage of efavirenz when administered concomitantly with rifampicin. Efavirenz is metabolized by the enzyme cytochrome P-450 (CYP), i.e. the CYP2B6 and CYP3A4 isozymes, of which rifampicin is an inducer. The induction of cytochrome P-450 by rifampicin is mediated by pregnane X (PXR) and constitutive androstane receptors (CAR) in the cell nucleus, resulting in a wide variation in the plasma efavirenz concentrations, such that a therapeutic failure or the occurrence of toxic effects are to be expected. The optimal dosage of efavirenz is commonly determined through pharmacokinetic studies, but this  is problematic in the combined use of the drug with rifampicin, due to the wide variation in study design, method, and sample size of each study. Ethnic factors and genetic polymorphism of the enzymes that metabolize efavirenz contribute to the problem of determining the optimal dose of this drug. Pharmacokinetic studies with good measurement parameters and methods are still necessary as the basis for determining the optimal dose of efavirenz in the Indonesian population.

Abstract

BackgroundHypertension is associated with endothelial-dependent vasodilation disorders, due to reduced nitric oxide (NO) availability and excessive angiotensin II (ANG-II) activation. The objective of this study was to determine the association between matrix metallopeptidase 9 (MMP-9) gene polymorphism and hypertension in ethnic Javanese in the 40-80 year age group. MethodsThis was a case-control study on 50 PROLANIS patients of family doctors meeting the inclusion criteria and 50 controls without hypertension. Subjects were hypertensive patients with constant systolic arterial pressure of >140 mmHg and diastolic arterial pressure of >90 mmHg, confirmed in three successive measurements The observed parameters were degree of MMP-9 polymorphism, and NO and ANG-II levels. Matrix metallopeptidase 9 polymorphism was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) using the SmaI restriction enzyme. MMP-9 polymorphisms were indicated by variation in band patterns. Degree of polymorphism in cases and controls were compared with NO and ANG-II levels in both groups. Data analysis was done using independent t-test.ResultsThe heterozygous (3 band) to normal (2 band) MMP-9 genotype ratio was 3:1 in hypertensives, but balanced in controls. In hypertensives, heterozygous GA and homozygous AA genotype frequencies were respectively 3.198 and 1.548 times higher than that of the GG genotype (p=0.008 and p=0.726). There was a statistically significant differences of NO and Ang-II levels between cases and controls (p=0.000 and p=0.000; respectively). ConclusionMatrix metallopeptidase 9 gene polymorphisms in hypertensive ethnic Javanese are associated with NO and angiotensin II levels.

Abstract

Aeromonas species are gram-negative, motile, facultative anaerobic, rod shaped, oxidase positive bacteria of the recently assigned family Aeromonadaceae. The significance of Aeromonas species as causative agent of human diarrhoea has recently been established. The aim of the present study was to investigate the distribution, and antibiotic sensitivity of Aeromonas in nonhospitalized children with diarrhea.One hundred and seventeen rectal swabs from children with diarhhea were cultured for isolation of Aeromonas organisms as the etiological agents. In addition to Aeromonas, other enteric pathogens were also isolated. Overall, the isolates of enteric pathogens amounted to 36.8%, consisting of Salmonella, Shigella, Aeromonas, and Vibrio. Aeromonas was only found in 5.1% of cultures, with a ratio of A. caviae and A. hydrophila of 2:1, while Salmonella made up the majority of causative organisms with an isolation frequency of 18.8%, followed by Shigella with 11.1%. In this study no isolates of Vibrio cholerae O1 were found as etiological agents of diarrhea; however, V. cholerae non-O1 and V. parahaemolyticus were found in small numbers (<1%). All isolates of Aeromonas were resistant to ampicillin and tetracycline, but sensitive to ciprofloxacin and ceftriaxone, as were the other enteric pathogens. Although the frequency of isolation of these enteric pathogens was higher than for Vibrio spp., their role in infective diarrhea was less clearcut in comparison with Salmonella and Shigella.

Abstract

INTRODUCTIONBlood urea nitrogen and creatinine levels are routine laboratory tests for evaluating renal function. Renal dysfunction has been related to worse prognosis of cardiovascular diseases. The purpose of this study was to determine the relationship between admission blood urea nitrogen and creatinine levels with in-hospital mortality in acute myocardial infarction patients. METHODSA cross-sectional study was performed using secondary data of 80 acute myocardial infarction patients hospitalized in Intensive Cardiac Care Unit of dr. Wahidin Sudirohusodo Hospital, Makassar, from June 2010 to July 2011. Admission blood urea nitrogen and creatinine levels were analyzed with Mann Whitney and Chi-Square tests.RESULTSMortality risk in the patients with blood urea nitrogen levels >50 mg/dL was 3.58 higher compared with those with blood urea nitrogen levels <50 mg/dL [OR=3.58; 95% confidence interval (CI) =1.27-10.11, p=0.013]. Mean admission creatinine levels in surviving and non- surviving patients were 0.99 ± 0.30 mg/dL and 1.70 ± 1.99 mg/dL, respectively (p=0.043). Mortality risk in patients with creatinine levels >1.1 mg/dL was 3.0-fold higher compared to patients with creatinine levels <1.1 mg/dL [OR=3.00; 95% confidence interval (CI) =1.13-7.92, p=0.024]. Multiple logistic regression showed blood urea nitrogen to be a better predictor of mortality than creatinine (OR= 3.583, p=0.016 vs OR 1.844, p=0.317).CONCLUSIONSPatients with high levels of blood urea nitrogen and creatinine had higher mortality risks than patients with normal levels. Blood urea nitrogen was a better predictor of mortality than creatinine.

Abstract

Cardiovascular disease (CVD) incidence increases with age and is frequently higher in the elderly.(1) Therefore prevention of CVD in the elderly through management of risk factors is important in order to reduce the risk of coronary heart disease (CHD). There are several risk factors of CVD that can be modified, such as smoking, physical activity, and unhealthy diet. Cessation of smoking is the most potent measure to prevent thousands of CVD events and death

Abstract

Cardiovascular disorders are the most common complications encountered in patients with type 2 diabetes mellitus (DM). The relationship is likely to be multifactorial and may also involve a specific, though ill-defined, diabetic cardiomyopathy. Patients with heart failure accompanied by DM have a reduced cardiac output compared with patients without DM. Thiazolidinediones (TZDs) are agonists of peroxisome proliferator-activated receptor gamma (PPARã) and have beneficial effects in the control of blood glucose and cardiovascular parameters, but the ability of these drugs to induce retention of plasma has to be taken into consideration in prescribing them for patients with DM at high risk of cardiovascular disease. The molecular mechanism of fluid retention by TZDs has not been fully elucidated. Available evidence indicate a possible role of epithelial sodium channels (ENaC) in causing the side effects of TZDs. This paper will discuss the mechanism of ENaC in inducing fluid retention and the management to be applied for anticipating these side effects.

Abstract

Worldwide, the proportion of people aged 60 and over is growing faster than any other age group. It has been well-established that the aging process can be associated with increased susceptibility to chronic conditions, disability, and co-morbidity, which however may be minimized or even partially reversed by physical activity. The assessment of physical activity is becoming an increasingly important component in the evaluation of elderly persons. Nutritional intake and status play an essential role in determining the physical activity level potentially capable of minimizing the health burden of older persons. The objective of this study was to find out whether nutritional intake and status were correlated with physical activity in community-dwelling older persons. The study population included 219 aged 60 to 69 years, of whom complete measures of socio-demographic characteristics, nutritional status, nutritional intake and physical activity were obtained. Serum total protein, albumin, globulin and hemoglobin concentration were measured as nutritional indicators (biomarkers). The nutrient content of food intakes was analyzed and calculated by “Nutrisurvey” software. Analysis indicated that there was a significant correlation between nutritional biomarkers [total protein (r=-0.211; p=0.002) and globulin (r=-0.247; p=0.000)] and physical activity. Compared to other food intakes, intakes of carbohydrate (r=0.241; p=0.001) and animal protein (r=0.149; p=0.027) were significantly correlated with physical activity. Our findings lend support to the existence among healthy older persons of a relationship between nutrional intake and status and physical activity.

Abstract

BACKGROUNDRed fruit oil (RFO) is popular in Indonesia especially in Papua. It is consumed by people for maintaining health and to treat diseases. Red fruit (Pandanus conoideus Lam) oil is reported to contain the antioxidants á-tocoferol and âcarotene.The aim of this study was to confirm the protective effect of RFOagainst decreased glutathione levels in the plasma and liver of rats induced by 2N-(2-fluorenyl) acetamide (2-FAA).METHODSWistar male rats weighing 200 ± 20 g were randomly assigned into a control group (receiving distilled water only) and three intervention groups, designated RFO, FAA, and RFO-FAA (n=6 rats per group). RFO was given RFO 10 ì l/g/BW/day, FAA received fluoroenylacetamide (FAA) at 40ìg/day, while RFOFAA received both RFO and FAA. At 4 weeks blood samples were taken from the tail. At 8 weeks the rats were sacrified for collection of blood and liver tissues. Ellman’s method was employed to determine the parameters of antioxidantglutathione (glutahione sulfhydryl/GSH). One-way ANOVA and Tukey post hoc test were used to compare glutathione levels between groups.RESULTSThis study showed that liver and plasma glutathione levels were not significantly lower in the RFO-FAA group than in the FAA group. Glutathione levels were significantly lower in plasma and liver homogenates of the RFO group compared with the control group and were not significantly different from those in theFAA group.CONCLUSIONAdministration of RFO in rats does not protect against decreased glutathione but is a potential source of oxidative stress.
