Peginterferon alfa-2a and peginterferon alfa-2b combined with ribavirin in patients with genotype 1 chronic hepatitis C: results of a prospective single-centre study.

Purpose: This prospective, randomized, single-centre study compared peginterferons alfa-2a and alfa-2b, combined with ribavirin, in treating patients infected with hepatitis C virus (HCV) genotype 1.

Material/methods: Hundred-and-one patients received 48 weeks of open-label treatment with peginterferon alfa-2a (180 μg/week) and 111 patients received peginterferon alfa-2b (1.5 μg/kg/week).

Identification of GPR39 receptor and ghrelin receptor in thyroid tissues in paediatric patients with immune and non-immune thyroid diseases.

The preproghrelin gene is responsible for generating ghrelin and obestatin, two gastric peptides with opposite effects on food intake. Obestatin suppresses food intake and digestive motility through interaction with GPR39 (GPCR). Ghrelin is supposed to be a link connecting metabolism and energy homeostasis with growth as the result of activation of the growth hormone secretagogue receptor (GHSR).

Asymptomatic and symptomatic glial cysts of the pineal gland.

Glial cysts of the pineal gland are benign and mostly asymptomatic incidental lesions found in the brain MRI or at autopsy examinations. In rare cases pineal cysts become symptomatic and require surgical intervention. Symptomatic glial cysts may be clinically and radiologically indistinguishable from cystic neoplasms of the pineal region; therefore, histopathological diagnosis is critical for further prognosis and therapy in operated patients.

[Analysis of Fas, FasL and Caspase-8 expression in thyroid gland in young patients with immune and non-immune thyroid diseases].

Introduction: Apoptosis, programmed cell death is a regulating mechanism enabling the removal of superabundantly produced and unnecessary at the certain moment cells. Disturbances of the apoptosis regulation contribute to the pathogenesis of many diseases, including autoimmune thyroid disorders. The aim of this study was to estimate expression of proapoptotic Fas/FasL and caspase-8 in thyroid tissues in patients with Graves' disease (GD), non-toxic nodular goiter (NTNG) and Hashimoto's thyroiditis (HT).

[Analysis of intracellular proapoptotic (Bax, Bak) and antiapoptotic (Bcl-2, Bcl-XL) proteins expression in thyrocytes from young patients with immune and non-immune thyroid disorders].

Apoptosis one of the form of programmed cell death is a physiological occurrence, requisite to the correct function of every organism. This is an active process that proceeds with a participation of the cellular metabolism embracing the activation of genes and the synthesis of proteins. The signal to apoptosis can be started practically in every cell of our organism.

[Comparison of early virologic response among patients with chronic hepatitis C infected with genotype non 2/3 treated with pegylated interferon alfa-2B and ribavirin in dependence with hepatic fibrosis stages].

Early virologic response (EVR) depending on various hepatic fibrosis was analyzed at 12 week of pegylated interferon alfa-2b (Pegintron, 12 KD) with ribavirin treatment among chronic hepatitis C patients (pts) infected with genotype non 2/3. The A group composed 29 pts. They were of staging 0 and grading 1.

[Study of the efficacy of combined therapy with interferon alfacon-1 and ribavirin for chronic hepatitis C].

The results of combined interferon alfacon-1 and ribavirin therapy of 94 patients with chronic hepatitis C were analyzed. Complete data, including sustained viral response (SVR), were obtained in 88 patients. 46.

[Cytofluorometric analysis of chosen markers of apoptosis CD95/CD95L (Fas/FasL) in thyroid tissues from young patients with Graves' disease and Hashimoto's thyroiditis].

Background: Apoptosis, one of the forms of programmed cell death, is a physiologic process of cell death that is central to normal development and occurs in response to a variety of physiologic and pathophysiologic stimuli. In the thyroid, abnormal apoptotic activity may be involved in a variety of diseases such as Hashimoto thyroiditis and Graves disease. The aim of this study was to estimate the expression of chosen apoptotic molecules CD95 (Fas) and CD95L (FasL) on the surface of thyroid follicular cells in application of mouse monoclonal antibodies #64 which recognized B antigen regions of thyroid peroxidase (TPO) and infiltrating inflammatory cells.
