    ABSTRACT: Respiratory syncytial virus (RSV) infection is the most common cause of hospitalization in infants and small children. The aim was to present a 13-months old boy diagnosed with acute airway infection, acute otitis media (AOM) and hepatitis during the RSV-infection. Serum catalytic activities of alkaline phosphatase (ALP), aspartate aminotranspherase (AST), alanine aminotranspherase (ALT), gamma glutamyl transpherase (GGT), lactate dehydrogenase (LD), and concentrations of bilirubin were monitored during hospitalization and at control examination. The child had clinical signs and symptoms of respiratory failure, AOM, and laboratory findings of virus infection and liver disease. On admission, catalytic activities of enzymes were markedly increased, especially the activity of ALP (10333 U/L, i.e. 24-fold increase in comparison with the upper reference limit). The highest increased in AST (339 U/L, 4.5-fold), ALT (475 U/L, 10.3-fold) and LD (545 U/L, 1.5-fold) were registered on the 3rd day, and the highest increase in GGT (68 U/L, 3.1-fold) occurred on the 11th day. Seven weeks after discharge AST, ALT, GGT and LD decreased into reference range, and ALP remain mildly increased (478 U/L, 1.1 fold increase). RSV was confirmed in nasal lavage fluid. Laboratory results in patient with RSV infection needs to be interpreted in the light of both, respiratory and extrapulmonary manifestations of the infection, respectively.

    ABSTRACT: Interferon-γ (IFN-γ) release assay (IGRA) is used for diagnosis of latent tuberculosis infection (LTBI), and for serial testing of active tuberculosis (TB). The aim of this study was to evaluate the results of IGRA for diagnosis and treatment monitoring of children with LTBI and children with TB. IGRA was performed in BCG vaccinated children before and six months after the beginning of treatment. A total of 59 BCG vaccinated children aged 4-18 years were investigated due to exposure to active TB. The participants were divided into two groups: Group 1, children with LTBI (N = 41), and Group 2, children with TB (N = 18). IGRA (QuantiFERON-TB Gold In-Tube) was performed twice, i.e., before treatment and at the end of prophylaxis and therapy. There was no significant difference in IFN-γ concentrations between Group 1 and Group 2 subjects either before or after the treatment. Difference between pre-treatment and post-treatment IFN-γ concentrations compared in either Group 1 or Group 2 was not statistically significant. During follow-up, children with LTBI did not develop active TB. In addition, in children with TB, signs and symptoms of TB improved with anti-TB therapy. This study showed that the concentrations of IFN-γ did not differ in children with LTBI and TB either before or at the end of treatment. IGRA may remain positive over a long period of time. It seems that IGRA is not useful for monitoring treatment of children with LTBI and children with TB.
