This article reviews a population pharmacokinetics studies conducted during the past few years in Serbia. Studies have included three the most frequently used antiepileptic drugs (valproate, carbamazepine and lamotrigine) and different populations of epileptic patients: children, adults and heterogeneous population composed of both children and adults. The review compares obtained values of population pharmacokinetic models of clearance of these drugs, and factors that are significantly determined, making brief comments on the results of other authors on the same topic. Individualization of drug dosage is the basis of rational therapy, and factors of variability will always be subject of scientific research.

Aim: Research into quality of life has become very important recently, since quality of life is increasingly used to characterise diseases and estimate the efficiency of therapeutics. The aim of this study was to determine significant factors that are associated with the quality of life of patients with schizophrenia accommodated in social welfare institutions. Material and methods: The study was conducted at the Institution for the Accommodation of Adults “Male Pcelice,” Kragujevac, Serbia. It was designed as a cross-sectional study. The quality of life was measured by using five distinct scales. The data on factors that might be associated with the quality of life were obtained from case records and the patients’ questionnaires. The association of every single factor was evaluated by using comparative analysis and the method of multiple linear regression. Results: Multiple linear regression shows that EuroQoL Five-dimensions – Five-Level scale score was associated with gender (B = −0.059 ± 0.021; p = 0.006) and daily dose (B = −0.051 ± 0.015; p = 0.001); Quality of Life Enjoyment and Satisfaction Questionnaire score was associated with the patient’s level of education (B = 2.873 ± 1.054; р = 0.007); the number of prescribed antipsychotics was associated with the Brief Psychiatric Rating Scale score (B = 3.150 ± 1.111; р = 0.007); the physical domain of the World Health Organization Quality of Life-BREF was associated with the year of disease onset (B = −0.142 ± 0.055; р = 0.011) and the daily dose (B = −2.335 ± 0.787; р = 0.004); the psychological domain of the World Health Organization Quality of Life-BREF was associated with gender (B = −2.686 ± 1.216; р = 0.029); the social relationship domain of the World Health Organization Quality of Life-BREF was associated with the level of education (B = 3.109 ± 1.289; р = 0.017) and the number of prescribed antipsychotics (B = −3.297 ± 1.516; р = 0.031); the environment domain of the World Health Organization Quality of Life-BREF was associated with the number of prescribed antipsychotics (B = −1.420 ± 0.653; р = 0,031). Conclusion: The quality of life of patients with schizophrenia was higher in males with a university degree, when the duration of the disease was shorter, negative symptoms were less pronounced, and with fewer side effects. Efforts to improve the quality of life in patients with schizophrenia accommodated in social welfare institutions should be made that could contribute to the prevention of adverse outcomes.

Cel pracy: Badania nad jakością życia nabrały ostatnio szczególnej wagi – coraz częściej kategoria ta jest stosowana do opisu chorób oraz oceny skuteczności leczenia. Celem badania była określenie istotnych czynników związanych z jakością życia pacjentów chorych na schizofrenię przebywających w placówkach psychiatrycznych stałego pobytu. Materiał i metoda: Badanie o charakterze przekrojowym zostało przeprowadzone wśród pacjentów Centrum Pobytu dla Osób Dorosłych „Male Pcelice” w miejscowości Kragujevac w Serbii. Jakość życia chorych na schizofrenię zmierzono za pomocą pięciu skal. Dane dotyczące czynników, które mogły mieć wpływ na jakość życia badanych, zostały pozyskane z dokumentacji medycznej pacjentów oraz z wypełnianych przez nich ankiet. W ocenie zależności pomiędzy jakością życia pacjentów a poszczególnymi czynnikami wykorzystano analizę porównawczą oraz metodę regresji wielorakiej. Wyniki: Metodą regresji wielorakiej wykazano, iż wynik skali EuroQoL Five-dimensions – Five-Level korelował z płcią pacjentów (B = −0,059 ± 0,021; p = 0,006) oraz dzienną dawką przyjmowanych leków (B = −0,051 ± 0,015; p = 0,001), wynik Quality of Life Enjoyment and Satisfaction Questionnaire – z poziomem wykształcenia (B = 2,873 ± 1,054; р = 0,007), liczba przyjmowanych leków przeciwpsychotycznych – z wynikiem skali Brief Psychiatric Rating Scale (B = 3,150 ± 1,111; р = 0,007), domena fizyczna skali World Health Organization Quality of Life-BREF – z czasem trwania choroby (rokiem wystąpienia choroby) (B = −0,142 ± 0,055; р = 0,011) oraz dzienną dawką przyjmowanych leków (B = −2,335 ± 0,787; р = 0,004), domena psychologiczna skali World Health Organization Quality of Life-BREF – z płcią (B = −2,686 ± 1,216; р = 0,029), domena społeczna skali World Health Organization Quality of Life-BREF – z poziomem wykształcenia (B = 3,109 ± 1,289; р = 0,017) oraz liczbą przyjmowanych leków przeciwpsychotycznych (B = −3,297 ± 1,516; р = 0,031), zaś domena środowiskowa skali World Health Organization Quality of Life-BREF – z liczbą przyjmowanych leków przeciwpsychotycznych (B = −1,420 ± 0,653; р = 0,031). Wnioski: Jakość życia chorych na schizofrenię objętych badaniem była wyższa u pacjentów płci męskiej z wyższym wykształceniem, o krótszym przebiegu choroby, z mniej dotkliwymi objawami oraz mniejszą liczbą skutków ubocznych. Poprawa jakości życia osób chorujących na schizofrenię przebywających w placówkach psychiatrycznych stałego pobytu pozwoli zapobiec niepomyślnym wynikom leczenia psychiatrycznego.

Changes of platelets’ function in preeclampsia

EN
Increased aggregation of platelets during preeclampsia was shown in several studies, yet several others reported no change. The aim of our study was to investigate platelet aggregation in a group of patients suffering from preeclampsia. In a cross-sectional study blood samples were taken from 89 hospitalized patients in the third trimester of pregnancy: 38 were suffering from mild to moderate preeclampsia and 51 patients were without preeclampsia. From the blood samples platelet aggregation, secretion of adenine nucleotides from platelets, concentration of energy-rich adenine compounds and levels of cyclic adenosine-mono-phosphate and cyclic guanosine mono-phosphate in platelets were measured. In the patients with preeclampsia, the adenosine diphosphate threshold for biphasic aggregation [odds ratio (OR):.75; 95% Confidence Interval (CI): 0.55–1.02; p<0.05], total adenine nucleotides concentration in the metabolic pool of platelets (OR:0.99; CI: 0.62–1.57; p<0.01) and cyclic adenosine-mono-phosphate (OR:0.81; CI: 0.57, 1.14; p<0.05) and cyclic guanosine mono-phosphate (OR:.78; CI: 0.55–1.09; p<0.05) levels in platelets were decreased in comparison with the control group, while adenylate energy charge in the metabolic pool of platelets (OR: >100.00; CI: 0.00->100.00; p<0.05) and secretion of adenosine triphosphate (OR:.13; CI: 0.00–14.26; p<0.05) and adenosine diphosphate (OR:.77; CI: 0.08–36.79; p<0.05) were increased. The results of our study show increased activation and aggregation of platelets in pregnant females with preeclampsia.
