RESUMO
PURPOSE: Tick-borne co-infections are a serious epidemiological and clinical problem. Only a few studies aimed to investigate the effect of tick-borne encephalitis (TBE) and human granulocytic anaplasmosis (HGA) co-infection in the course of the inflammatory process and the participation of chemokines in the pathomechanism of these diseases. The aim of the study was to evaluate CCL-4, CCL-17, CCL-20, and IL-8 serum concentrations in patients with HGA, TBE and HGAâ¯+â¯TBE co-infection. METHODS: Eighty-seven patients with HGA (nâ¯=â¯20), TBE (nâ¯=â¯49) and HGAâ¯+â¯TBE (nâ¯=â¯18) were included to the study. The control group (CG) consisted of 20 healthy people. Concentrations of cytokines were measured in serum using commercial ELISA assays. In patients with TBE and HGAâ¯+â¯TBE inflammatory markers were assessed during the acute and convalescent period. The results were analyzed using non-parametric tests with pâ¯<â¯0.05 considered as significant. RESULTS: Before treatment, significantly higher concentrations of IL-8, CCL-4 and CCL-20 were observed in HGA patients. CCL-4 and CCL-20 concentrations were significantly higher in TBE patients compared to CG. Concentrations of IL-8, CCL-4, and CCL-20 were significantly higher in HGAâ¯+â¯TBE than in CG. After treatment, a significant reduction of IL-8, CCL-4, and CCL-20 concentrations in TBE patients and IL-8 in HGAâ¯+â¯TBE co-infection was observed. CCL-4 concentration was higher in HGAâ¯+â¯TBE co-infection in comparison to patients with TBE after treatment. CONCLUSIONS: Our study confirms that concentrations of IL-8, CCL-4, and CCL-20 are increased in the course of HGA and TBE. Their concentrations in serum may be used to monitor the course of TBE and HGA, as well as possibly detect co-infections with the diseases.

INTRODUCTION: Scabies is a parasitic skin disease caused by Sarcoptes scabiei. About 200 million casesworldwide each year in people of all ages are reported. AIM OF STUDY: Retrospective analysis of records of patients hospitalized at the Department with scabies. MATERIALS AND METHODS: Six-year retrospective analysis of medical records of patients hospitalized with scabies at the Department of Dermatology. Gender, age of patients, comorbidities, clinical course of the disease and treatment were considered. RESULTS: In this period 193 patients were hospitalized with scabies, 96 females (49.7%) and 97 males (50.3%), including 33 children (17%). Mean age of patients was 52.9. Skin lesions persisted 142 days in average; reoccurrence was noted in 14% of cases. Lesions were observed most often in winter (31%). The most common manifestations were erosions (80.8%), excoriations (73.6%), papules (72.6%) and crusts (24.3%), localized mainly on trunk (92%), lower (91%) and upper (86%) limbs. 181 patients (93.8%) reported pruritus which intensified at night in 35.8%. Previous contact with people with scabies reported 41 patients (21%). The most common comorbidity was hypertension, diabetes mellitus and coronary heart disease. Accompanying dermatoses were eczema, secondary superinfection and psoriasis. 85 patients (44%) were overweight or obese. Patients received mostly topical permethrin (57%), crotamiton (29%), glicocorticosteroids (73%) and antibiotics (11%), also oral antihistamines (91%). CONCLUSIONS: Analysis revealed more frequent occurrence in adults with no evident sex prevalence. Greater incidence in winter may be caused by people's tendency to spend more time indoors closer to each other at this time of year. Pruritus, the most common subjective symptom, typically worsens at night.

AIM AND BACKGROUND: Herpes zoster is a viral disease caused by the reactivation of varicella-zoster virus (VZV) which remained latent in the cranial nerve or dorsal root ganglia. Cell-mediated immunity is known to decline with age as part of immunosenescence and can lead to the reactivation of VZV. Whereas herpes zoster is usually mild in healthy young persons, older patients are at increased risk for complications. In the present study we investigated the serum cytokine profile (IL-17, IL-23, IL-21, IL-4, IL-12), representing cellular and humoral immunity and assessed the level of VZV IgG antibodies in patients with herpes zoster. METHODS: We investigated the serum concentrations of IL-17, IL-23, IL-21, IL-4, IL-12 and the level of VZV IgG antibodies in 23 patients with herpes zoster who did not develop superinfection. The control group was represented by 21 individuals in similar age with no inflammatory and infectious diseases. Cytokine and antibodies levels were measured by ELISA method. Statistical analysis was performed using the ROC curve (receiver operating characteristic), t-test, Welch's t-test, and nonparametric tests with STATISTICA 10 software. RESULTS: In patients with herpes zoster, the serum level of IL-17, IL-23, IL-21, IL-4 and IL-12 as well as VZV IgG antibodies titer were statistically significantly increased compared to control group. CONCLUSION: Our results confirm the broad activation of the immune system involving humoral and cell-mediated immunity.

INTRODUCTION AND OBJECTIVE: Acute parvovirus B19 (B19V) infection is a proven risk for pregnant women and fetus. The aim of this study was to determine the prevalence of B19V antibodies among pregnant women or planning pregnancy, who were referred for preventive toxoplasmosis screening. MATERIAL AND METHODS: Between 2007-2010, 55 women in the age between 21 and 40 years were tested for both B19V IgG and IgM antibodies and sociodemographic information was collected. RESULTS: Among the study group, the mean age was 30 years, 43.6% of women were positive only for B19V IgG antibodies, 9% were positive for both B19V IgG and IgM antibodies and 11% were positive only for B19V IgM antibodies. Women negative for B19 IgG antibodies (47.3%) were considered as a high-risk group of B19V viremia. The serological profile indicating infection with Toxoplasma gondii was considered as a risk factor for fetal distress. The T. gondii IgG antibodies were detected in 51% cases, in 32.7% antibodies were positive for both IgG and IgM, while in 16.3% cases both IgG and IgM were negative. CONCLUSIONS: B19V infection and overlapping of other independent risk factors during pregnancy pose a significant hazard to fetus during development. Therefore, we recommend further broadening the epidemiological database of B19V infection prevalence among women. B19V infection should be taken into account during differential diagnosis as a cause of miscarriage.
