Administration of biological therapy (BT) in rheumatoid arthritis (RA) patients is often associated with hematological complications, which result in switching among therapies. Thus, there is an instant need for suitable screening parameters that will help to individualize the therapy and minimize the onset of adverse effects. We analyzed the hematological profile of 99 RA patients receiving TNFα (Adalimumab - ADA, Golimumab - GOL, Etanercept - ETA) or IL-6 receptor (Tocilizumab - TCZ) inhibitors in order to find possible indicators to improve personalization of RA therapy. BTs significantly affect the levels of observed hematological parameters. In contrast to TNF-α inhibitors, TCZ normalized almost all monitored hematological parameters to values of healthy donors. Only GOL from the TNF-α inhibitors studied, was able to normalize neutrophil counts, as well as platelet indicators. Importantly, effects on the blood parameters (e.g. lymphocytes or platelet count) differ even within the same therapeutic group (anti-TNFα). Variable effects of individual biological agents in RA treatment point to importance to evaluate the patient's hematological profile to improve the selection of suitable BT. It will help to personalize the administration of BT and prevent unnecessary switching from an effective therapy just because of provocation of avoidable hematological complications.

Nitro-oleic acid (NO2-OA), pluripotent cell-signaling mediator, was recently described as a modulator of the signal transducer and activator of transcription 3 (STAT3) activity. In our study, we discovered new aspects of NO2-OA involvement in the regulation of stem cell pluripotency and differentiation. Murine embryonic stem cells (mESC) or mESC-derived embryoid bodies (EBs) were exposed to NO2-OA or oleic acid (OA) for selected time periods. Our results showed that NO2-OA but not OA caused the loss of pluripotency of mESC cultivated in leukemia inhibitory factor (LIF) rich medium via the decrease of pluripotency markers (NANOG, sex-determining region Y-box 1 transcription factor (SOX2), and octamer-binding transcription factor 4 (OCT4)). The effects of NO2-OA on mESC correlated with reduced phosphorylation of STAT3. Subsequent differentiation led to an increase of the ectodermal marker orthodenticle homolog 2 (Otx2). Similarly, treatment of mESC-derived EBs by NO2-OA resulted in the up-regulation of both neural markers Nestin and β-Tubulin class III (Tubb3). Interestingly, the expression of cardiac-specific genes and beating of EBs were significantly decreased. In conclusion, NO2-OA is able to modulate pluripotency of mESC via the regulation of STAT3 phosphorylation. Further, it attenuates cardiac differentiation on the one hand, and on the other hand, it directs mESC into neural fate.

Barthov syndróm je zriedkavé mitochondriové ochorenie viazané na chromozóm X. Je charakterizované širokým spektrom klinických príznakov a laboratórnych nálezov, z ktorých najtypickejšie je postihnutie srdca, myopatia, neutropénia, rastová retardácia, 3-metylglutakónová acidúria. Považuje sa za poddiagnostikovanú klinickú jednotku s rizikom náhleho úmrtia v detskom veku. V kazuistike prezentujeme prvého pacienta s dokázaným Barthovým syndrómom na Slovensku, u ktorého sa ochorenie manifestovalo v 3. týždni života kardiálnou dekompenzáciou s nálezom ľavokomorovej nonkompaktnej kardiomyopatie a hepatálnou dysfunkciou so závažnou koagulopatiou. Na základe metabolického vyšetrenia, klinických príznakov a pozitívnej rodinnej anamnézy – úmrtie dvoch chlapcov v dojčenskom období na ochorenie srdca, bola diagnóza Barthovho syndrómu potvrdená molekulovo-genetickým vyšetrením v 7. týždni života.
Barth syndrome is a rare mitochondrial disorder linked to chromosome X. It is characterized by a wide range of clinical signs and laboratory findings, most typically heart disease, myopathy, neutropenia, growth failure and 3-methylglutaconic aciduria. It is considered to be a underdiagnosed disease with the risk of sudden death in childhood. We report the first patient in Slovakia with proven Barth syndrome manifested by cardiac decompensation with the finding of left ventricular noncompaction cardiomyopathy and hepatic dysfunction with severe coagulopathy in the 3rd week of life. Based on the metabolic examination, clinical signs and a positive family history of two boys who died in infancy due to cardiac disorder, the diagnosis of Barth syndrome was genetically confirmed in the 7th week of life.
