The aim of this report is to emphasize the risk of acquiring TBE by the consumption of raw milk and dairy products. In April-May 2015, we registered the first outbreak of tick-borne encephalitis in Croatia in seven members out of ten exposed persons who consumed raw goat milk or cheese from the same supplier. Infection was confirmed by TBEV enzyme-linked immunosorbent assay (ELISA) in all patients. None had been vaccinated nor had observed a tick bite.
In this study, the most common isolated serotype was ADV type 2. Most affected children were younger than 3 years. ADV infections in young children can present with prolonged fever, leukocytosis and significantly elevated C-reactive protein and erythrocyte sedimentation rate, mimicking bacterial infections.
Kawasaki disease (KD) is an acute systemic vasculitis of childhood. Due to development of coronary artery aneurysms (CAA) it is considered the most common cause of acquired heart disease in children. The clinical and laboratory features of patients with complete and incomplete KD were compared in order to identify the possible predictors of CAA development. A cross-sectional study of children with KD treated at the University Hospital for Infectious Diseases, Zagreb, between January 2003 and December 2012 was conducted. A total of 111 KD patients were included; 70.3% patients had complete KD. Patients with complete KD had more frequently rash, changes on extremities and mucous membranes, as well as higher serum bilirubin, aminotransferases, gamma-glutamyl transferase and lactate dehydrogenase levels. Patients with incomplete KD had longer duration of fever before the diagnosis (8 vs. 7 days) and delayed IVIG treatment (day 8 vs. 7). CAA was detected in seven children (6.3%). Disease duration before hospitalization >6 days (OR 7.16, 95% CI 1.51-100.35), age <6 months (OR 25.86, 95% CI 1.68-398.35) and platelet count >771 after the 7th day of disease (OR 13.33, 95% CI 2.19-80.87) were independently associated with CAA development. The diagnosis and treatment in incomplete KD can be delayed due to the absence of major criteria. Age, duration of symptoms prior hospitalization and platelet count were identified as independent predictors of CAA development.
A total of 1,442 patients with symptoms of chronic prostatitis were examined over a 4-year period at the Outpatient Department for Urogenital Infections, University Hospital for Infectious Diseases Dr. Fran Mihaljević, Zagreb, Croatia. The inclusion criteria for chronic prostatitis caused by Ureaplasma urealyticum were the presence of clinical symptoms, presence of U. urealyticum in expressed prostatic secretion (EPS) or voided urine collected immediately after prostatic massage (VB3), absence of U. urealyticum in urethral swabs and absence of other possible pathogens of chronic prostatitis in EPS or VB3. A total of 63 patients with prostate infection caused by U. urealyticum were available for this pilot study. The patients were randomized according to a computer randomization list to receive a total dose of 4.5 g of azithromycin given as a 3-day therapy of 1 × 500 mg weekly for 3 weeks or doxycyline 100 mg b.i.d. for 21 days. Patients’ sexual partners were treated at the same time. Clinical efficacy and tolerability of the administered drug as well as possible adverse events were evaluated during, at the end and 4–6 weeks after completion of therapy. Bacteriological efficacy was evaluated 4–6 weeks after completion of therapy. Treatment groups did not differ regarding age, distribution of urethral, prostatic, sexual and other symptoms, or digitorectal prostatic examination. Five patients treated with doxycycline had nausea. In the group of patients with prostate infection caused by U. urealyticum, the eradication rate was not significantly different with regard to the administered azithromycin (25/32) or doxycycline (23/31). Clinical cure did not significantly differ with regard to the administered azithromycin (22/32) or doxycycline (21/31).
A total of 123 patients, older than 18 years of age, with symptoms of chronic prostatitis and inflammatory findings as well as the presence of Chlamydia trachomatis confirmed by DNA/RNA DIGENE hybridization method in expressed prostatic secretion or in voided bladder urine collected immediately after prostatic massage, were examined. The patients were randomized to receive a total of 4.5 g of azithromycin for 3 weeks, given as a 3-day therapy of 1 x 500 mg weekly or clarithromycin 500 mg b.i.d. for 15 days. Patients' sexual partners were treated at the same time. Clinical and bacteriological efficacy were evaluated 4-6 weeks after the end of therapy. In the group of patients with chronic chlamydial prostatitis the eradication rates (azithromycin 37/46, clarithromycin 36/45) and the clinical cure rates (azithromycin 32/46, clarithromycin 32/45) were not significantly different with regards to the administered drug (p > 0.05). In the group of patients with asymptomatic chlamydial prostatitis the eradication rates (azithromycin 11/16, clarithromycin 10/15) were not significantly different with regards to the administered drug (p = 1.00, OR = 1.1).
Severe RSV infections and frequent recurrence could be related to the altered polarization of type-2/type-1 T cells. This increases the importance of determining distinctive chemokines and chemokine receptor profiles on memory T cells. We analyzed systemic adaptive T cell response in the acute (n = 17) and convalescent phase (n = 7) of RSV-infected children, in the acute (n = 11) and convalescent phase (n = 6) of children with other viral respiratory infections (adenovirus and influenza virus), and in healthy children (n = 18). Expression of CCR4 and CXCR3 on effector-memory (TEM) and central-memory (TCM) T cells was compared between tested groups. Serum concentrations of specific chemokines were determined. High CXCL10 levels were detected in acutely infected children regardless of virus pathogen, whereas increased CCL17 production was RSV-specific. Higher percentages of CCR4+ CD4 TEM cells in acute RSV infection were accompanied with higher percentages of CXCR3+ CD8 TEM cells, whereas the development of long-lived memory CXCR3+ CD4 and CD8 TCM cells seems to be compromised, as only children with other viral infections had higher percentages in the convalescent phase. Presence of type-2 and type-1 adaptive antiviral immune response, together with insufficient development of long-lived type-1 T cell memory, could play an important role in RSV pathogenesis and reinfection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
