The influence of the immune system deregulation on the risk of schizophrenia is increasingly recognized. The aim of this study was to assess the influence of serum interleukin-6 (IL-6) level together with the polymorphism in its gene (IL6 -174G/C) and high sensitivity C-reactive protein (hsCRP) levels on clinical manifestation and cognition in schizophrenia(More)
OBJECTIVE Doxepin is a tricyclic antidepressant formulated as a mixture of E-(trans) and Z-(cis) stereoisomers. Cytochrome P450 2D6 (CYP2D6) catalyzes the hydroxylation of E-doxepin and E-N-desmethyldoxepin stereospecically. There is evidence that tricyclic antidepressants might inhibit CYP2D6 activity but there is no data about the influence of doxepin on(More)
There are studies showing that gene polymorphisms within the transforming growth factor-β (TGF-β) signaling constitute schizophrenia risk variants. However, the association between TGFB1 gene polymorphisms (+869T/C and +915G/C), TGF-β level with schizophrenia course, and its symptomatology together with cognitive functioning has not been investigated so(More)
Overwhelming evidence indicates the involvement of immune-inflammatory processes in the pathophysiology of major depressive disorder (MDD). Peripheral cytokine alterations serve as one of most consistently reported indices of subthreshold inflammatory state observed in MDD. Although cytokines cannot pass directly through the blood-brain barrier, a number of(More)
Therapeutic drug monitoring (TDM) is used to optimise therapy by an assessment of the drug's plasma concentration. The indications for TDM according to Preskorn are: 1. well defined relationships between plasma concentration of a drug and its therapeutic efficacy, and between plasma level and adverse events and/or toxicity, 2. narrow therapeutic index of a(More)
AIM Genetically determined activity ofCYP2D6 may be modified by some drugs through inhibition processes. Inhibition properties of TCA's were confirmed mainly in in vitro studies. The aim of the study was to assess the influence of clomipramine on CYP2D6 activity in vivo. METHOD 11 patients diagnosed with depression according to ICD-10 and DSM-IV (major(More)
The paper reports the case of a 42-year-old woman with a diagnosed catatonic-paranoidal syndrome and a noted dysfunction as regards lymphocyte subpopulation and the production of some cytokins: Tumor Necrosis Factor (TNF) and interferons (IFN). As the first phase of the treatment had proved unsuccessful and there appeared symptoms hinting at the possibility(More)
We aimed to investigate whether antipsychotics differentially impact insight and whether these effects appear because of improvement in psychopathological manifestation in 132 first-episode schizophrenia patients and 201 acutely relapsed schizophrenic patients, who were followed up for 12 weeks. Olanzapine and risperidone were administered to first-episode(More)
Polymorphisms in immune-inflammatory response genes are believed to impact schizophrenia susceptibility. However, it remains unknown whether immunogenetic factors play a role in the etiology of deficit schizophrenia (D-SCZ). Therefore, we genotyped four polymorphisms in genes encoding two immune system regulatory proteins (CTLA-4 rs231775 and CD28(More)
The paper describes: 1. Drug oxidation process. 2. Cytochrome P-450 Isozymes. 3. Genetic polimorphism of drug oxidation. 4. Spartein test. Metabolic ratio, extensive and poor metabolizers. 5. Cytochrom P-450 and drug metabolism. 6. Inhibition of drug oxidation process and inhibitors of CYP450. 7. Influence of CYP450 genetic polimorphism on development of(More)
