    ABSTRACT: Objectives Congenital cytomegalovirus (CMV) infection is one of the most common intrauterine diseases. In all, 1% of live births is affected by cytomegalovirus infection, while 90% neonates with perinatal infection do not show symptoms of disease. Symptomatic CMV is present in 5–10% of children. Typical clinical signs of CMV infection are microcephalia, mental retardation, progressive major amblyacousia, and neuromuscular infection. Hypoacusis is present in 30–60% of children with congenital symptomatic CMV – in most cases it is bilateral and applies to high frequency hearing loss. The purpose of this article is to emphasize the importance of hearing evaluation in children with congenital and acquired cytomegalovirus infection. Patients and methods A group of 70 children had serological and genetic screening for CMV DNA, using PCR method, in urine and blood. In this group, 52 children were diagnosed with congenital CMV and 18 children had acquired CMV. Audiological examinations including PTA, ABR, TEOAE and immittance audiometry were performed. Results Bilateral sensorineural hearing losses were found in 9 children, associated with mental and physical retardation, brain malformation and microcephalia, and unilateral losses in 3 children. In 40 cases, we did not observe hearing loss, although the level of bilirubin was high, and splenomegaly, hepatomegaly and paralysis of facial nerve were present. In the group of children with acquired CMV, we did not notice hearing loss. Conclusions This research proved that CMV infection often caused hearing loss. In spite of this, all children with congenital and acquired CMV should be monitored and assessed throughout their lifetime by an audiologist.

    ABSTRACT: Introduction Cohort study evaluated dendritic cells (DCs) subsets in portal and peripheral blood of patients with pancreatic cancer (PC) and chronic pancreatitis (CHP). Material and Methods Myeloid type 1 (mDCs1) and 2 (mDCs2), plasmocytoid (pDCs) and SLAN+ DCs were assessed in PC (n=20) and CHP (n=6) patients. Results Percentage of mDCs1 was significantly lower in PC patients when compared to CHP (0,48±0,26 vs 0,76±0,3; p=0,038) only in portal, but not peripheral blood. Discussion Further studies to assess the functional properties of portal blood DCs and their applicability in anticancervaccination are needed.

    ABSTRACT: Toxoplasma gondii has a highly clonal genetic structure classified into three major genetic types, I, II, and III, plus additional recombinant and atypical strains. In humans, type I and atypical strains usually associate with severe toxoplasmosis. Type II strains, predominantly identified in European countries and the United States, correlate with a differential course of toxoplasmosis. During pregnancy, the important protective role of the placenta against maternal-fetal T. gondii transmission has been reported. T. gondii preferentially colonizes extravillous trophoblasts as compared to syncytiotrophoblasts. The latter compartment was suggested to act as the real barrier to the fetal dissemination of T. gondii. Alterations in immune response to particular T. gondii strains were observed. Higher transcription levels of IP-10, IL-1β, IL-6, IL-10, IL-12 cytokines, and NF-κB translocation to the nucleus were more often documented for type II strains than type I strains. Since the induction of IL-12 during type II infection was Myd88-dependent, the involvement of Toll-like receptors (TLRs) in the immunity against these strains was suggested. Differential expression of TLRs depends on placental cell types and gestational age. The expression of TLR2 and TLR4 in the first trimester of pregnancy was reported only for villous cytotrophoblasts and extravillous trophoblasts, but not for syncytiotrophoblasts. The involvement of single-nucleotide polymorphisms (SNPs) in the TLR genes in infectious pathogenicity, including toxoplasmic retinochoroiditis, points at a possible involvement of TLR alterations in immunity against T. gondii. We conclude that studies on TLR contributions in the maternal-fetal transmission of particular parasite strains and congenital toxoplasmosis are warranted.
