Introduction. Cytomegalovirus is the most common cause of infections in the post-transplantation period. A reliable and timely laboratory diagnosis of cytomegalovirus infection in patients on dialysis and in the post-transplantation period is significant because of the possibility of preventing or mitigating the effects of cytomegalovirus disease. The main objective of this study was to compare serological and molecular polymerase chain reaction methods to determine the presence of cytomegalovirus in the blood of dialysis patients. Material and Methods. The study included 28 dialysis patients, potential renal transplant recipients. All patients were evaluated for the presence of cytomegalovirus in the blood by a quantitative polymerase chain reaction method as well as in the serum for the presence of anti-cytomegalovirus Immunoglobulin G and Immunoglobulin M antibodies. Results. According to the comparative enzyme-linked immunosorbent assay for detecting antibodies in dialysis patients, 96.4% were once exposed to the virus, while 7.1% showed current infection not confirmed by polymerase chain reaction test. No statistically significant association was found between the positive finding of anti-cytomegalovirus Immunoglobulin M antibodies and the findings of the polymerase chain reaction cytomegalovirus method when Chi-square (?2) and Fisher?s correlation tests were conducted (p > 0.05). Conclusion. Due to 7.1% false positives results for the presence of anti-cytomegalovirus Immunoglobulin M antibodies in the serum of immunocompromised dialysis patients, not confirmed by polymerase chain reaction test, serological techniques are not reliable in detecting active cytomegalovirus infection causing positive finding of anti-cytomegalovirus Immunoglobulin M, so confirmation of cytomegalovirus deoxyribonucleic acid by polymerase chain reaction method is required.

The modern way of life contributes to the higher frequency of a complex state medically called metabolic syndrome (MetS), which is an inevitable consequence of several most common diseases of modern civilization. Patients with MetS have three times higher risk of experiencing a heart attack or a stroke and twice higher possibility to die from them. Serbia holds the infamous third place in Europe in mortality from heart disease, just behind Russia and Ukraine. The study explores the correlation of every combination of genotypes of apoE (apolipoprotein E) and LRP1 (low density receptor- related protein 1) genes with presence of MetS, and the connection with each anthropometric and biochemical parameter in both tested groups. Study demonstrates the impact of genotype combinations on the emergence and development of the MetS in Serbia. 63 patients and 30 controls were included in the study, aged from 19 to 65. Each person genotype was determined by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) profile. Odds ratio (OR) values showed that the presence of apoE e3e4/LRP1 CC genotype combination of genotypes in patients multiplies the chance (7.6 times) for the occurrence of the MetS in comparison to the presence of other genotype combinations. Determining the genetic basis of MetS is one of the necessary steps in the prevention of disease, saving the cost of treatment, and in the design of targeted therapies.

Introduction. The alpha-1 antitrypsin deficiency is the best described genetic cause of chronic obstructive pulmonary disease. The study of the alpha-1 antitrypsin deficiency, as the most important genetic risk factor for chronic obstructive pulmonary disease, is an important step in developing a strategy for the prevention and treatment of this disease. The aim of the study was detection of homozygous and heterozygous deficient gene alleles (protease inhibitor Z and protease inhibitor S) for alpha-1 antitrypsin in the group of patients with chronic obstructive pulmonary disease with the predominance of lung emphysema, as well as determination of a positive correlation between the serum levels of alpha-1 antitrypsin and the corresponding alpha-1 antitrypsin genotype. Material and Methods. The study included 90 patients, mutually unrelated individuals, hospitalized due to lung emphysema. The control group included 10 subjects, with no clinical signs of lung emphysema, but with a family history of chronic obstructive pulmonary disease. We attempted to identify the most common deficient alleles (protease inhibitor Z and protease inhibitor S) and the concentration of alpha-1 antitrypsin in the serum of the examinees. The polymorphism between the two allelic forms, protease inhibitor Z and protease inhibitor S, was detected by real-time polymerase chain reaction. Results. Protease inhibitor MM genotype alpha-1 antitrypsin was present in all 90 patients with the diagnosis of pulmonary emphysema, and the serum levels of alpha-1 antitrypsin were within the range of reference values. In the control group, there were two cases with mutated protease inhibitor MZ genotype, and in these 2 subjects the serum level of alpha-1 antitrypsin was at the lower limit of reference values. Conclusion. In patients diagnosed with lung emphysema, protease inhibitor MM genotype of alpha-1 antitrypsin and normal serum alpha-1 antitrypsin levels, the genetically- determined deficiency of alpha-1 antitrypsin is not responsible for the development of chronic obstructive pulmonary disease.

The determination of genetic background in metabolic syndrome (MetS) represents one of the necessary steps to prevent the disorder, thus reducing the cost of medical treatments and helping to design targeted therapy. The study explores the association between individual alleles of the LRP1 gene and the diagnosis of MetS to find correlation between the low-density lipoprotein receptor-related (LRP1) gene polymorphism and each individual anthropometric and biochemical parameter. The study included 93 males and females, aged from 19 to 65, divided into two groups. The genotype of each person was determined from the restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) profile. Results indicated the association of the T allele form of exon 3 LRP1 gene with development and progression of MetS that further pointed out its negative impact on tested anthropometric and biochemical parameters. The presence of the T allele in patients multiplies the chance of occurrence of deviations from the reference values of body mass index (BMI), (4.24-fold) and low-density lipoprotein (LDL) (20.26-fold) compared to C allele carriers. The results showed that T allele presence multiplies the chance (4.76 fold) for the occurrence of MetS in comparison to C allele carriers. Correlation found that the T allele of the LRP1 gene with MetS determinants is not negligible, therefore, the T allele may be considered as a risk factor for MetS development.

The roles of the pharmacist were transformed throughout the history and modern pharmacist as we know now beside providing products and playing in optimization of medicines has a crucial role in ensuring the efficacy and safety of applied drugs. A better life quality, global health and safety is the major goal of the 21st century and to achieve that great span of roles pharmacy profession involves now. The paper highlighted new roles of the pharmacist today in order to better understand the transition of the pharmacy profession.
