RESUMEN
Background: Coronary artery disease as a consequence of atherosclerosis is the most common cause of morbidity and mortality in type 2 Diabetes Mellitus (DM) patients. Homocysteine (HCY), as one of the risk factors, and uric acid (UA) as the most common antioxidant in serum have their roles in the processes of inflammation and atherogenesis, which underlie the pathogenesis of acute myocardial infarction (AMI). The effect of HCY in cardiovascular disease is thought to be manifested primarily through oxidative damage, implying a potential correlation between the HCY level and antioxidant status. Since the data related to the diagnostic significance of both HCY and UA in diabetic patients with AMI are conflicting, and so far not reported in Bosnian patients, this research aimed to examine the association of HCY and UA levels with glomerular filtration rate (eGFR) and explore the pathophysiological significance of these data in Bosnian diabetic patients with AMI. Methods: This prospective research included 52 DM type 2 patients diagnosed with AMI. Blood samples were taken on admission and used for biochemical analysis. Results of the biochemical analyses were statistically analysed. Results: Elevated HCY and UA levels were observed in diabetic patients. Females have higher HCY compared to males. A positive correlation was revealed between HCY and UA and was confirmed with different HCY levels in subgroups with different UA level. A negative correlation was observed between UA and HbA1c, as well as between both HCY and UA with eGFR. Conclusions: These results contribute to the clarification of the biochemical mechanisms characteristic in AMI patients with DM. According to these results, we believe that joint measurement of HCY and UA could enable a better assessment of the prognosis for this group of patients. This kind of assessment, as well as regression analysis, can identify high-risk patients at an earlier stage when appropriate interventions can influence a better outcome in such patients.
RESUMEN
BACKGROUND: Altered levels of many hematological parameters have been directly associated with diabetes in adults, while studies on children with type 1 diabetes mellitus are lacking. The aim of this study was to determine hematological indices in diabetic Bosnian children in comparison to healthy controls as well as to correlate their levels to blood glucose and hemoglobin A1c. METHODS: 100 healthy and 100 children with type 1 diabetes mellitus (age 1-18) were included in this study. Complete blood count, hemoglobin A1c, and glucose were tested. Results were analysed by IBM SPSS Statistics version 23. RESULTS: Significant differences (p<0.05) between healthy and diabetic children were found in relation to HbA1c, glucose, mean platelet volume, the number of white blood cells and erythrocytes, hematocrit, hemoglobin and MCH values. No gender differences or significant age differences were seen for hemoglobin, hematocrit, and MCV, while platelets, MPV, and MCH differed by age only in healthy children. When diabetic children were classified according to HbA1c levels, significant differences were seen for erythrocyte count and hematocrit value (p=0.013 and 0.019, respectively). The number of erythrocytes and white blood cells correlated significantly with HbA1c (p=0.037 and 0.027, respectively). CONCLUSIONS: Lower levels of erythrocytes, hematocrit, and hemoglobin in diabetic compared to healthy children indicate possible development of anemia, while higher MCV, MCH, and MPV values indicate an alteration in erythrocyte morphology. Hematological indices could be a useful inexpensive tool in the diagnosis and follow up of type 1 diabetes in children.
RESUMEN
The response to metformin, the most commonly used drug for the treatment of type 2 diabetes (T2D), is highly variable. The common variant rs7903146 C>T within the transcription factor 7-like 2 gene (TCF7L2) is the strongest genetic risk factor associated with T2D to date. In this study, we explored the effects of the TCF7L2 rs7903146 genotype on metformin response in T2D. The study included 86 newly diagnosed patients with T2D, incident users of metformin. Levels of fasting glucose, insulin, HbA1c, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, and anthropometric parameters were measured prior to metformin therapy, and 6 and 12 months after the treatment. Genotyping of the TCF7L2 rs7903146 was performed by the Sequenom MassARRAY® iPLEX® platform. At baseline, the diabetes risk allele (T) showed an association with lower triglyceride levels (p = 0.037). After 12 months of metformin treatment, the T allele was associated with 25.9% lower fasting insulin levels (95% CI 10.9-38.3%, p = 0.002) and 29.1% lower HOMA-IR index (95% CI 10.1-44.1%, p = 0.005), after adjustment for baseline values. Moreover, the T allele was associated with 6.7% lower fasting glucose levels (95% CI 1.1-12.0%, p = 0.021), adjusted for baseline glucose and baseline HOMA-%B levels, after 6 months of metformin treatment. This effect was more pronounced in the TT carriers who had 16.8% lower fasting glucose levels (95% CI 7.0-25.6%, p = 0.002) compared to the patients with CC genotype. Our results suggest that the TCF7L2 rs7903146 variant affects markers of insulin resistance and glycemic response to metformin in newly diagnosed patients with T2D within the first year of metformin treatment.

BACKGROUND: FTO, a gene recently discovered in genomewide associated studies for type 2 diabetes mellitus (T2D), play an important role in the management of energy homeostasis, nucleic acid demethylation and regulation of body fat mass by lipolysis. The aim of this study was to analyze the association of FTO rs8050136 A>C genetic variant with clinical and biochemical parameters of T2D in the population of West Balkan region (Bosnians and Herzegovinians and Kosovars). METHODS: The study included 638 patients with T2D and prediabetes and 360 healthy controls of both genders, aged from 40 to 65 years. Patients were recruited at the Clinical Centre University of Sarajevo, University Hospital of Clinical Centre in Banja Luka, General Hospital in Tesanj and Health Centre in Prizren. Genotyping of analyzed FTO polymorphism rs8050136 A>C was performed by qPCR allelic discrimination. RESULTS: Genotype frequencies of the analyzed polymorphism were comparable between patients with T2D, prediabetic patients, and healthy population. Logistic regression analyses didn't show significant association of FTO rs8050136 A allele with increased risk of T2D. However, risk A allele was significantly associated with higher levels of HbA1c, insulin, HOMA-IR index, diastolic blood pressure, and inflammatory markers (fibrinogen and leukocytes) as well as showed tendency of association with increased values of obesity markers (BMI, waist and hip circumference). CONCLUSIONS: Results of our study showed a significant association of FTO genetic variant rs8050136 A>C with the major markers of insulin resistance, obesity and inflammation, opening new avenues for solving many unclear questions in the pathogenesis of T2D.
RESUMEN
Background Previous studies reported conflicting results regarding association of insulin receptor substrate 1 (IRS1) gene variation with type 2 diabetes (T2D) and insulin resistance (IR) in different ethnic groups. We examined the association of rs7578326, rs2943641, and rs4675095 in the IRS1 gene with T2D and related traits in a population from Bosnia and Herzegovina, which is one of the European countries with the highest T2D prevalence of 12.5%. Methods Our study included 390 T2D patients and 252 control subjects. Biochemical parameters, including fasting glucose (FG), fasting insulin (FI), homeostasis model assessment insulin resistance index (HOMA-IR), and HbA1c were measured in all participants. Genotyping analysis was performed by Mass Array Sequenom iPlex platform. Results Our results demonstrated that rs7578326 and rs4675095 variants were associated with increased FG levels. The rs7578326 was also associated with higher FI, HOMA-IR (B = 0.08, 95% CI [0.01, 0.15], padd = 0.025; B = 0.079, 95% CI [0.006, 0.150], padd = 0.033, respectively) in T2D, and with HbA1c (B = 0.034, 95% CI [0.003, 0.065], pdom = 0.035) in non-drug-treated T2D. In contrast, rs2943641 C allele was associated with lower FG levels in control subjects (B = -0.17, 95% CI [-0.03, -0.002], padd = 0.030) and HbA1c (B = 0.03, 95% CI [0.002, 0.06], pdom = 0.040) in non-drug-treated T2D. Conclusions We report the association between common variants in IRS1 gene with insulin resistance, glucose, and HbA1c levels in Bosnia and Herzegovina's population.

Aim To determine the relationship of homocysteine (HCY), uric acid (UA) and C-reactive protein (CRP) in serum of patients with acute myocardial infarction (AMI) prior to application of percutaneous coronary intervention (PCI) and their level of correlation in serum of patients with normal and elevated CRP (predictor of worse cardiovascular outcomes). Methods The study involved 85 patients with diagnosed AMI. Before the PCI, venous blood samples were taken into the vacuum test tubes. The analysis of HCY, UA, inflammatory markers CRP and neutrophil to lymphocyte ratio (NLR) as well as lipoprotein status were performed on a different type of analysers and according to accepted protocols of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC). Results Elevated level of both HCY and UA in AMI patients as well as a positive correlation between HCY and UA level was observed. Classification of patients on the basis of mean UA concentration showed significant difference at the level of HCY concentration (p=0.022). Conclusion Since HCY and UA participate in the atherosclerotic process and their metabolism, as well as the effects on the cardiovascular system show significant overlaps, their serum level should be analysed synchronously with the level of CRP and NLR (indicators of significant inflammatory process in vessels). Considering a potential link between all parameters observed, further research involving a greater number of patients and including the post treatment effects should be conducted.

Aim To investigate whether or not additional treatment of ischemic heart disease with trimetazidine could improve effort tolerance and overall quality of life of patients with ischemic heart disease. Methods The study included 200 patients with ischemic heart disease. The sample was divided into 2 randomly selected groups: experimental and control group. The diagnostic procedures included: trade-mill test according to Bruce protocol, heart ultrasound for assessment of ejection fraction, test for the assessment of quality of life and subjective problems (Short Form SF 36). Patients were tested for time of discharge from hospital, after 6 and 12 months, including re-evaluation of the overall condition of the previous period. Results Patients have been tested for the tolerance of effort with the measurement Metabolic Equivalent of TASK (METs), which is the equivalent of physical labor. Patients treated with trimetazidine since the time of hospital discharge achieved an average of 3.68, after 6 months 5.68, and after 12 months 7.79 METs. The control group achieved 3.68, 3.59 and 3.87 METs, respectively. Using Mann-Whitney test no difference at discharge time (p=0.880), but after six and twelve months there was some difference (p<0.001). Results of ejection fraction measured by echocardiography were similar. No difference between the two groups with regard to time of discharge (p=0.821, but p<0.001 after six and twelve months, respectively). Conclusion Patients treated with conventional therapy including trimetazidine have better tolerance to effort and better ejection fraction on heart ultrasound examination in comparison with those treated without trimetazidine, so trimetazidin improve the metabolic balance of heart muscle.

Aim To analyse the long-term impact of altered metabolism on the level of mediators of inflammatory response in female patients with type 2 diabetes. Methods This study included 97 female patients with type 2 diabetes and 107 female, nondiabetic control subjects, who were recruited at the Clinical Centre University of Sarajevo and the General Hospital Tesanj. The effects of glycaemic control on markers of inflammatory response represented by C-reactive protein (CRP), fibrinogen, leukocytes, sedimentation rate, and cytokine IL-6 were tested. All subjects were free of evidence of infections, surgery, thyroid disease, polycystic ovarian syndrome, active liver and kidney damage. All biochemical analyses were performed according to standard International Federation of Clinical Chemistry (IFCC) protocols. Results A significant increase of fibrinogen (p<0.001), CRP (p=0.001), interleukin-6 (p=0.013), leukocytes (p<0.001) and sedimentation rate (p=0.008) in diabetic female population compared to control subjects was found. A significant correlation between CRP and haemoglobin A1c (p=0.035), interleukin-6 and glucose (p=0.032), IL-6 and body mass index (p=0.007) was found. Conclusion Our data suggest that inflammation plays an important role in the pathogenesis of diabetes in female diabetic population. A more detailed study on a far larger number of subjects is needed if they were to be used effectively as biomarkers in the primary prevention of type 2 diabetes in this population.

OBJECTIVE: Tobacco cigarette smoking is one of the major leading causes of death throughout the world. Smoking has both acute and chronic effect on haematological parameters. The aim of the present study was to assess the extent of adverse effects of cigarette smoking on biochemical characteristics in healthy smokers. SUBJECTS AND METHOD: One hundred and fifty six subjects participated in this study, 56 smokers and 100 non-smokers. The smokers were regularly consuming 10-20 cigarettes per day for at least 3 years. Complete blood cell count was analyzed by CELL-DYN 3700 fully automatic haematological analyzer. RESULTS: The smokers had significantly higher levels of white blood cell (p<0,001), hemoglobin (p=0,042), mean corpuscular volume (p=0,001) and mean corpuscular hemoglobin concentration (p<0,001). All other measured parameters did not differ significantly. Cigarette smoking caused a significant increase (p<0,001) in red blood cells, white blood cells (p=0,040), hemoglobin (p<0,001), hematocrit (p=0,047) and mean corpuscular hemoglobin (p<0,001) in males in comparison to female smokers. CONCLUSION: In conclusion, our study showed that continuous cigarette smoking has severe adverse effects on haematological parameters (e.g., hemoglobin, white blood cells count, mean corpuscular volume, mean corpuscular hemoglobin concentration, red blood cells count, hematocrit) and these alterations might be associated with a greater risk for developing atherosclerosis, polycythemia vera, chronic obstructive pulmonary disease and/or cardiovascular diseases.

INTRODUCTION: Because of increasing prevalence of T2MD worldwide, it's very important to recognize risk factors for diabetic complications, as soon as possible. Symptoms of complications appear a few or many years after tissue damage. So, it's imperative to establish surveillance of diabetics with laboratory and other diagnostic procedures for early recognition of diabetic complications. Follow up of clinical curs of diabetes, by using databases of patients, provide possibility for permanent analysis of important laboratory parameters and any changes could be registered. Although an emerging evidence suggests a strong association of ALT (alanine aminotransferase) and γGT (gamma glutamyl transferase) activity with type 2 diabetes mellitus (T2DM), only a limited number of studies have analyzed the association of AST (aspartate aminotransferase), ALT, γGT, and ALP (alkaline phosphatase) activities in controlled T2DM. MATERIAL AND METHODS: Gender differences are of special interest in trying to follow diabetes progression and development of its complications. Here the activities of ALT, AST, γGT, ALP were analyzed as well as levels of glycosylated hemoglobin (HbA1c) and fasting plasma glucose (FPG) in 40 T2DM patients and 40 age-matched healthy subjects. Blood samples were collected from all participants in regular 3-months intervals up to 6 months period. Standard IFCC enzyme protocols were used to determine enzyme activities. RESULTS AND DISCUSSION: In first measured interval, significantly higher activities of ALT (p= 0,050) and glucose levels (p=0,045) were shown in male. A significant correlation was shown between ALT and AST activity with FPG and HbA1c levels in first and third measured interval. ALT activity was much higher in the group of patients with poor glycemia control. Average levels of activities of enzymes stay nearly in normal limits, but changes of enzymes activities should be recognized as soon as possible, earlier than tissue changes and diabetic complications become irreversible.
RESUMEN
AIM: To investigate association of two LPIN1 gene variations with main traits of metabolic syndrome (MS) (waist circumference, body mass index, blood pressure, triglycerides, HDL-cholesterol and fasting glucose levels) in population from Bosnia and Herzegovina. METHODS: This study included 43 patients with metabolic syndrome and 43 healthy controls from General Hospital in Tesanj, Bosnia and Herzegovina. Subjects were genotyped for two LPIN1 gene variations (rs11693809: C>T and rs2716610: C>T) by real time PCR method. RESULTS: In control subjects LPIN1 polymorphism, rs2716610: C>T, was significantly associated with a lower body mass index (BMI) (p=0.008) and waist circumference (p=0.008). The second analyzed rs11693809: C>T polymorphism was associated with lower blood HbA1c levels (p=0.048) in a group of MS patients. CONCLUSION: Results of our study suggest that rs2716610: C>T polymorphism of LPIN1 gene could have a protective effect against development of metabolic syndrome, while rs11693809: C>T might affect a glucose control in patients with MS.

Type 2 diabetes mellitus (T2DM) is a worldwide epidemic with considerable health and economic consequences. T2DM patients are often treated with more than one drug, including oral antidiabetic drugs (OAD) and drugs used to treat diabetic complications, such as dyslipidemia and hypertension. If genetic testing could be employed to predict treatment outcome, appropriate measures could be taken to treat T2DM more efficiently. Here we provide a review of pharmacogenetic studies focused on OAD and a role of common drug-metabolizing enzymes (DME) and drug-transporters (DT) variants in therapy outcomes. For example, genetic variations of several membrane transporters, including SLC2A1/2 and SLC47A1/2 genes, are implicated in the highly variable glycemic response to metformin, a first-line drug used to treat newly diagnosed T2DM. Furthermore, cytochrome P450 (CYP) enzymes are implicated in variation of sulphonylurea and meglitinide metabolism. Additional variants related to drug target and diabetes risk genes have been also linked to interindividual differences in the efficacy and toxicity of OAD. Thus, in addition to promoting safe and cost-effective individualized diabetes treatment, pharmacogenomics has a great potential to complement current efforts to optimize treatment of diabetes and lead towards its effective and personalized care.

INTRODUCTION: The enzyme 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) catalyzes the conversion of the hormonally inactive cortisone to active cortisol, thus facilitating glucocorticoid receptor activation in target tissues. Increased expression of 11beta-HSD1 in adipose tissue has been associated with obesity and insulin resistance. In this study, we investigated the association of two 11beta-HSD1 gene (HSD11B1) polymorphisms with the metabolic syndrome (MetS) and its characteristics in the Bosnian population. MATERIALS AND METHODS: The study included 86 participants: 43 patients diagnosed with MetS and 43 healthy controls. Subjects were genotyped for two HSD11B1 gene polymorphisms: rs846910: G > A and rs45487298: insA, by the high resolution melting curve analysis. Genotype distribution and an influence of genotypes on clinical and biochemical parameters were assessed. RESULTS: There was no significant difference in the mutated allele frequencies for the two HSD11B1 gene polymorphisms between MetS patients and controls. In MetS patients, no significant associations between disease-associated traits and rs45487298: insA were found. Regarding rs846910: G > Avariant, heterozygous patients (G/A) had significantly lower systolic (P = 0.017) and diastolic blood pressure (P = 0.015), lower HOMA-IR index (P = 0.011) and higher LDL-cholesterol levels (P = 0.049), compared to the wild-type homozygotes. In the control group, rs45487298: insA polymorphism was associated with lower fasting plasma insulin levels (P = 0.041), lower homeostasis model assessment insulin resistance (HOMA-IR) index (P = 0.041) and lower diastolic blood pressure (P = 0.048). Significant differences between rs846910: G > A genotypes in controls were not detected. Haplotype analysis confirmed the association of rs45487298: insA with markers of insulin resistance in the control subjects. CONCLUSIONS: Our results indicate that a common rs45487298: insA polymorphism in HSD1181 gene may have a protective effect against insulin resistance.

In this paper we would like to briefly introduce readers to the situation in the field of laboratory medicine in Bosnia and Herzegovina, with a focus on training in the field of medical biochemistry. As in some of neighboring countries, term Medical biochemist is the usual name for the Clinical biochemist or Clinical chemist in Bosnia and Herzegovina. Despite the difficult period through which the profession had passed in the last two decades, laboratory work, particularly clinical biochemistry, has managed to retain the necessary quality and keep pace with the developed world. In post war period, Society of Medical Biochemists of Bosnia and Herzegovina held regular meetings each year as a part of "life long learning" process, where both scientific and vocational lecturers presented their work. A single law on the state level would provide us with more defined and precise answers, such as: who can get a specialization, how long should last the training for medical biochemistry specialists (duration in years). This law should be in consent with the program described in EC4 or other documents given by the EFCC (European Federation of Clinical Chemistry and Laboratory Medicine) and IFCC (International Federation of Clinical Chemistry and Laboratory Medicine).

INTRODUCTION: Laboratory diagnosis of medical biochemistry activity plays a significant role in the Primary Health Care Center (PHCC), dominated by Family medicine and diagnostic services. Medical biochemical diagnosis has a visible place at all levels of health care, which shows the number of requests for laboratory diagnosis, number and type of required laboratory tests. MATERIALS AND METHODS: The study included 1000 requests for laboratory tests at the PHCC in Gracanica in primary health care units. We made an analysis of the most common laboratory tests in the requests by doctors from primary health care based on requests for laboratory diagnosis. RESULTS: The requests of primary health care units in PHCC laboratory tests are required at all levels of service: urine, WBC, SE, glucose, total bilirubin, ALT, AST, AF, CK, cholesterol, HDL cholesterol, triglycerides, creatinine, urea, uric acid, CRP, fibrinogen, calcium and phosphorus. The following requirements are the most common laboratory tests with 94% representation: urine, WBC, glucose, cholesterol, triglycerides, aminotransferases, creatinine, and urea. In 1000 requires was required total of 5333 laboratory tests. Test requirements of a general practice make 44, 1%; FM doctors account for 40% and the requirements of other specialists (pediatricians, gynecologists and specialists of occupational medicine) are 15, 3%. The doctors in family practice most often required: glucose, urine, WBC, SE, TGL., Chol., ALT, AST, creatinine and urea. General practitioners are demanding more cholesterol and triglycerides, a family medicine doctors are demanding lower cholesterol and triglycerides and higher CRP, fibrinogen, total bilirubin, ALT, AST, and other specialists the most demanded urine and WBC. DISCUSSION: Laboratory diagnosis is a common diagnosis, which shows the representation of required number and type of laboratory tests. In requirements of PHC units in PHCC laboratory tests are required at all levels of service: urine, WBC, SE, glucose, bilirubin, ALT, AST, AF, CK, cholesterol, HDLchol., triglycerides, creatinine, urea, uric acid, CRP, fibrinogen, calcium and phosphorus. The following requirements are the most common laboratory tests at the primary level: urine, WBC, glucose, cholesterol, urea, and found the secondary level of triglycerides, index levels and did not clear the number of searches required by the standards and norms of PHC.

BACKGROUND AND AIMS: N-acetyltransferase 2 (NAT2) is a drug-metabolizing enzyme, which is genetically variable in human populations. Polymorphisms in the NAT2 gene have been associated with drug efficacy and toxicity as well as disease susceptibility. Recently, an association of NAT2 gene variation with risk of type 2 diabetes mellitus (T2DM) has been suggested. This is the first study performed in a population from Bosnia and Herzegovina (BH) in which the frequency of two common NAT2 polymorphisms, 341T>C (NAT2*5) and 590G>A (NAT2*6) was determined in diabetic patients. METHODS: The frequency of the NAT2*5 (341T>C) and NAT2*6 (590G>A) polymorphisms was analyzed by employing TaqMan SNP Genotyping Assays (Applied Biosystems) in a group of 63 patients with T2DM and 79 nondiabetic subjects. RESULTS: Our data demonstrated that the frequencies of NAT2*5 (341T>C) and NAT2*6 (590G>A) polymorphisms in BH population were in line with the Caucasians genotype data. The NAT2*5 and NAT2*6 alleles were in high linkage disequilibrium (D' = 0.969). Strinkingly, there was a significant difference in genotype frequencies for NAT2*5 (p <0.05) and NAT2*6 (p <0.001) polymorphisms between diabetic and nondiabetic subjects. NAT2*5 polymorphism was associated with 2.4-fold increased risk for developing T2DM (adjusted OR = 2.40, 95% CI = 1.10-5.25, p = 0.028). On the contrary, NAT2*6 variant significantly decreased by 5-fold susceptibility to the disease (adjusted OR = 0.20, 95% CI = 0.09-0.43, p <0.001). CONCLUSIONS: Our data demonstrated that NAT2 genetic variation appeared to be an important risk factor in development of T2DM.

AIM: Lipin 1 is a recently discovered multifunctional protein involved in the metabolism of lipids, while PPARgamma is involved in adipocyte differentiation, and regulation of lipid metabolism. Up to now, LPIN1 and PPARG gene polymorphisms have been associated with type 2 diabetes, metabolic syndrome, and central obesity. In this study, we hypothesized that genetic variants within LPIN1 and PPARG genes were associated with traits of metabolic syndrome. Correlation between biochemical parameters (including but not limited to, glucose, HbA1c, insulin levels, HDL and LDL cholesterol, triglycerides, serum proteins, liver enzymes) and frequency of polymorphisms in LPIN1 (rs11693809 and rs2716610) and PPARG gene (rs10865710, rs3856806 and rs1801282), was tested in this study. METHODS: The study included 70 patients diagnosed with metabolic syndrome and type 2 diabetes. Two polymorphisms of LPIN1 gene (rs11693809 and rs2716610), and three polymorphisms of PPARG gene (rs10865710, rs385806 and rs1801282) were analyzed by real time PCR and conventional PCR-RFLP methods. RESULTS: Our analysis revealed correlation between insulin levels and rs11693809 LPIN1 polymorphism in diabetic patients. Also the results of this study showed an association of rs10865710 and rs385806 polymorphism of PPARG with HDL cholesterol and LDL plus total cholesterol levels, respectively. CONCLUSION: These data reflect an association of analyzed PPARG and LPIN1 gene polymorphisms with values of insulin, HDL, LDL and total cholesterol witch indicates an important role of these genes in lipid metabolism and pathogenesis of type 2 diabetes and metabolic syndrome.

AIM: Differences in the frequency of distribution of the cytochrome P450 (CYP) allelic variants have been demonstrated between distinct ethnic groups, contributing to observed interindividual variation in drug response. In this study we determined, for the first time, prevalence of the common allelic variants of the polymorphic CYP enzymes, CYP3A4*1B and CYP3A5*3, in the population of Bosnia and Herzegovina (BH). METHODS: Genomic DNA was extracted from blood samples collected from 140 unrelated subjects. A real-time PCR was used for the detection of CYP polymorphisms, with the application of the specific TaqMan SNP Genotyping Assay (Applied Biosystems) for CYP3A5*3, while CYP3A4*1B was genotyped by high-resolution melting analysis. RESULTS: Our results have shown that the distribution of CYP3A4*1B and CYP3A5*3 alleles was in line with the data reported in European Caucasians. We confirmed that CYP3A4*1B mutant allele is rare in Caucasians, being present in only 5.1% individuals. However, CYP3A5*3 polymorphism was found to be predominant in the Bosnian population with an incidence of 94%, similarly to other European populations tested so far. Interestingly, we have demonstrated a strong linkage disequilibrium between CYP3A5*3 and CYP3A4*1B alleles. No significant difference in allele frequencies for CYP3A4*1B and CYP3A5*3 has been shown between male and female subjects participating in our study. CONCLUSION: Our data demonstrated the high prevalence of CYP3A5*3 allele in Bosnian population, indicating significance of analysis of CYP3A5 and CYP3A4 polymorphisms and corresponding allele frequencies in specific ethnic groups. Importantly, results of this study may lead to translation of pharmacogenetics and individualized therapeutic approach in current clinical practices in BH.

AIM: To analyze usefulness of measurement amino-terminal pro-B type natriuretic peptide of (NT pro-BNP) as the one of parameters of water overload in patients with chronic kidney diseases. METHODS: A total number of 277 patients with chronic kidney diseases (CKD) were followed up in the period often years between January 2000 and July 2010. Patients with creatinine clearance of 60 ml/min or less were included in the study. Changes of creatinine clearance, and in last five years changes of NT pro-BNP were followed. Water overload was analyzed using chest x-ray in relation with concentration of NT pro-BNP in the blood. RESULTS: Decrease of clearance of creatinine ranged from average 54.7 ml/min in the first year to 14.6 ml/min in the fifth year of the monitoring. Average NT pro-BNP level in patients without any sign of water overload was 94 pg/ml (SD 21), mean value in those with Kerley lines was 231 pg/ml/L (SD 64), in those with clear signs of water overload but without pleural effusion it was 525 pg/ml (SD 223), and in those with water retention including pleural effusion it was 1606 pg/ml (SD 1134). Using test of multiple correlation a statistically significant correlation between X-ray signs of water overload and NT pro-BNP concentration was shown, p < 0.05. CONCLUSION: Measurement of NT pro-BNP was increased in the beginning of water overload in patients with CKD. Increased value of NT pro-BNP may be found earlier than any other signs of water overload. NT pro-BNP was a useful parameter in estimation of water overload in these patients.

BACKGROUND: Polymorphisms in HSD11B1, the gene encoding 11ß-hydroxysteroid dehydrogenase type 1 enzyme, have been associated with obesity, metabolic syndrome, and type 2 diabetes. In this study, we present an optimized high-resolution melting (HRM) method for genotyping two common polymorphisms of the HSD11B1 gene: rs846910: G>A and rs45487298: insA. METHODS: One hundred DNA samples from patients with polycystic ovary syndrome and healthy controls were genotyped by HRM. The results were compared with those obtained with classic polymerase chain reaction followed by restriction fragment length polymorphism analysis. RESULTS: Various approaches were used during HRM specificity optimization. With the optimized method, genotyping accuracy of 100% was achieved. CONCLUSIONS: HRM analysis is a fast, simple, and cost-effective method compared with the alternative genotyping approaches. The work required for optimizing the method (improvement of specificity) is minor compared to the advantages.
