BACKGROUND: AFP serum levels are considered as diagnostic and specific for hepatocellular carcinoma (HCC) in patients with liver cirrhosis (LC). AIM: This study aimed to examine the diagnostic value of AFP in the distinguishing of patients with HCC from patients with LC, and to analyse the potential correlation between AFP levels and liver disease stages. MATERIAL AND METHODS: Fifty patients with LC and fifty patients with HCC were included in this study. The majority of the patients were males, while the HBV aetiology was dominant. RESULTS: Significant differences between LC and HCC patients were detected for AST, ALT, GGT, bilirubin, AFP and AP. Patients with HCC had higher AFP values compared to LC. There was no significant correlation between the size of the tumour lesion and serum AFP levels. A positive correlation between AFP concentration and GGT activity was determined, as was the negative correlation between AFP and age of the subjects. The AFP value of 23.34 ng/m showed high sensitivity (84%) and specificity (82%). CONCLUSION: The size of the surface below the ROC curve (AUC) was 0.877 (0.80-0.95), which makes AFP a good biomarker and this diagnostic test is sufficient to separate patients with HCC and LC.

Background: Heteromorphic variants including Yq12 material, being inserted or added to autosomal chromosomes have been reported for chromosomes 1, 7, 11, 13, 14, 15, 21 and 22. Here we describe a novel insertion of Yq12 heterochromatin into a chromosome 17; to the best of our knowledge no similar cases have been reported previously. Methods: GTG-, C-banding, fluorescence in situ hybridization (FISH), and homemade human heterochromatin specific multicolor FISH probes set (HCM-mix) were used to define the abnormality. A whole chromosome painting (wcp) probe for #17 together with a probe for Yq12 heterochromatin was hybridized to the patient sample. Additionally, Y microdeletion PCR was done to detect possible AZF subregional deletions. Results: The male patient had normal sperm analysis and no AZF deletions on Y chromosome. GTG and Cbanding showed an additional band on chromosome 17q21. FISH studies revealed that the insertion was derived from Yq12 heterochromatin. Conclusions: The heterochromatin insertion on 17q21 originating from Yq12 chromosome did not affect the spermatogenesis of aberration carrier and is probably not the cause of infertility in these partners. However, a new heteromorphic variant was identified in this case.

Microdeletion syndromes are caused by chromosomal deletions of less than 5 megabases which can be detected by fluorescence in situ hybridization (FISH). We evaluated the most commonly detected microdeletions for the period from June 01, 2008 to June 01, 2015 in the Federation of Bosnia and Herzegovina, including DiGeorge, Prader-Willi/Angelman, Wolf-Hirschhorn, and Williams syndromes. We report 4 patients with DiGeorge syndromes, 4 patients with Prader-Willi/Angelman, 4 patients with Wolf-Hirschhorn syndrome, and 3 patients with Williams syndrome in the analyzed 7 year period. Based on the positive FISH results for each syndrome, the incidence was calculated for the Federation of Bosnia and Herzegovina. These are the first reported frequencies of the microdeletion syndromes in the Federation of Bosnia and Herzegovina.

Aim: The aim of prenatal diagnostics is to provide information of the genetic abnormalities of the fetus early enough for the termination of pregnancy to be possible. Chromosomal abnormalities can be detected in an unborn child through the use of cytogenetic, molecular- cytogenetic and molecular methods. In between them, central spot is still occupied by cytogenetic methods. In cases where use of such methods is not informative enough, one or more molecular cytogenetic methods can be used for further clarification. Combined use of the mentioned methods improves the quality of the final findings in the diagnostics of chromosomal abnormalities, with classical cytogenetic methods still occupying the central spot. Material and methods: Conducted research represent retrospective-prospective study of a four year period, from 2008 through 2011. In the period stated, 1319 karyotyping from amniotic fluid were conducted, along with 146 FISH analysis. Results: Karyotyping had detected 20 numerical and 18 structural aberrations in that period. Most common observed numerical aberration were Down syndrome (75%), Klinefelter syndrome (10%), Edwards syndrome, double Y syndrome and triploidy (5% each). Within observed structural aberrations more common were balanced chromosomal aberrations then non balanced ones. Most common balanced structural aberrations were as follows: reciprocal translocations (60%), Robertson translocations (13.3%), chromosomal inversions, duplications and balanced de novo chromosomal rearrangements (6.6% each). Conclusion: With non- balanced aberrations observed in the samples of amniotic fluid, non- balanced translocations, deletions and derived chromosomes were equally represented. Number of detected aneuploidies with FISH, prior to obtaining results with karyotyping, were 6.

Background: HCV infection is characterized by a tendency towards chronicity. Acute HCV infection progresses to chronic infection in 70% of cases. Hepatitis C virus infection can cause progressive liver injury and lead to fibrosis and eventually cirrhosis. The degree of histologic fibrosis is an important marker of the stage of the disease. One of current standard treatment for CHC infection is the combination of PEG-IFN α and ribavirin. Objectives: The aim of the study was to investigate the effect of the therapy with Peginterferon alfa-2a or alfa-2b plus Ribavirin on evolution of liver fibrosis in patients with chronic hepatitis C. Also, our aim was to examine whether there was a difference between the genders in the efficacy of these antiviral therapy. Our goal also was to determine effect of the therapy with Peginterferon alfa-2a or alfa-2b plus Ribavirin on evolution of liver steatosis in patients with chronic hepatitis C. Patients and Methods: A retrospective study was made of chronic hepatitis C patients who had been treated from 2005 to April 2014 at the Clinic of Gastroenterohepatology, Clinical Center University of Sarajevo. We reviewed 40 patient medical records to collect demographic, epidemiological and clinical information, as information on liver biopsies that was performed prior to the antiviral therapy and FibroScan® test that was performed after the antiviral therapy. For the processing of data SPSS (Statistical Package for the Social Sciences Program) for Windows, ver. 21.0 statistical software was used. Comparisons between qualitative and quantitative variables were performed using the Student t-test. Mann Whitney U test was used to compare differences in variables such as fibrosis stage and steatosis grade. A value of p<0.05 was considered as statistically significant. Results: After treatment, there was a statistically significant increase in the number of patients with no fibrosis (p<0.05). There was no statistically significant reduction in the number of patients with cirrhosis (F4) (p>0.05). There was significantly higher decrease of fibrosis progression at the patients that were in an mild-to-moderate fibrosis (F1/F2/F3), patients that were in advanced stage of fibrosis (F4) at the time of the pre-treatment did not have a statistically significant fibrosis reduction. We found significant association in evolution of fibrosis after treatment with PEG-IFN α2a (40) kD and PEG-IFNα2a (12,5) kD with ribavirin (p< 0.05). We also found significant association in evolution of steatosis after treatment with PEG-IFN α2a (40) kD and PEG-IFNα2a (12,5) kD with ribavirin (p < 0.05). There was statistically significant differences (p<0.05) between genders within fibrosis qualitative evolution. Conclusions: There were significant regression of fibrosis especially at the patients that were in an mild-to-moderate fibrosis (F1/F2/F3), patients that were in advanced stage of fibrosis (F4) at the time of the pre-treatment did not have a statistically significant fibrosis reduction after treatment with PEG-IFN α2a (40) kD and PEG-IFNα2b (12,5) kD with ribavirin. Our results showed significant improvement in steatosis in patients infected with HCV after treatment with PEG-IFN α2a (40) kD and PEG-IFNα2b (12,5) kD with ribavirin. Those results provides further evidence for direct involvement of HCV and antiviral therapy in the pathogenesis of hepatic steatosis. Female gender showed a higher degree of fibrosis reduction.
