PURPOSE: Increased fecal calprotectin is a sensitive marker of various types of intestinal inflammation. We investigated correlations between high fecal calprotectin concentration and serum inflammatory markers in children with different intestinal diseases with diarrhea with/without blood and/or abdominal pain, to test whether the combination of these markers can differentiate potential patients with inflammatory bowel disease. MATERIALS/METHODS: The study included 128 children with high fecal calprotectin concentration (>150ug/g) and symptoms suggesting bowel disorders, hospitalized in the years 2013- 2015...

PURPOSE: In most cases gastroesophageal reflux disease proceeds without macroscopic erosions in the esophagus. We aimed to clarify if abnormalities detectable in magnifying endoscopy may offer additional diagnostic criteria for gastroesophageal reflux disease and to what histopathologic structures do they correspond. PATIENTS/METHODS: Esophageal mucosa above and below Z-line was evaluated under x115 magnification in 67 gastroesophageal reflux disease patients (11 with erosive reflux disease, 28 with Barrett's esophagus, 28 with nonerosive reflux disease) and in 12 patients without gastroesophageal reflux disease (negative control group)...

PURPOSE: Maternal obesity can unfavorably influence offspring body composition, muscle strength, and possibly muscle's adaptability to training, but the human studies are scarce. Therefore, we aimed to investigate the effect of maternal obesity on offspring muscle strength responses to resistance training intervention in elderly frail women. MATERIALS/METHODS: Recruited participants were elderly frail women offspring of lean/normal weight mothers (n = 19, mean body mass index (BMI): 22...

PURPOSE: Folic acid is an essential vitamin participating in DNA synthesis and repair. Recently folic acid has been shown to stimulate DNA-repair capacity in dermal fibroblasts in response to injury. Thus, the present study aimed to investigate the effects of topical folinic acid, a 5-formyl derivative of tetrahydrofolic acid, on wound healing using rat wound model. MATERIALS AND METHODS: A rat wound model was established, and the wound healing was evaluated by macroscopic and histological analyses among vehicle control, 2...

PURPOSE: The risk of vitamin E deficiency is of primary concern in cystic fibrosis patients. However, early diagnosis and routine vitamin E supplementation can lead to its normal or even high levels. In the present study, we assessed vitamin E status in a large group of cystic fibrosis patients. Moreover, we also aimed to establish determinants of its body resources in cystic fibrosis patients. MATERIAL AND METHODS: The study group comprised 211 cystic fibrosis patients aged from 1 month to 48 years...

PURPOSE: The aim of the study was to assess cardiac and autonomic function in patients with Crohn's disease and explore their relation to disease duration using cardiovascular reflex tests. MATERIALS AND METHODS: Cardiovascular parameters, baroreflex sensitivity, spectral-indices of short-term heart rate variability and blood pressure variability were compared between patients with Crohn's disease in remission (n = 30) and a control group (n = 29). Cardiac autonomic function was assessed during response to standing (tilt) and deep breathing test (expiration/inspiration ratio-E/I)...

PURPOSE: Previous retrospective claims database analyses reported increased prevalence and earlier onset of cardiovascular comorbidities in patients with versus without hemophilia A. A comprehensive chart review was designed to further investigate previous findings. METHODS: This retrospective chart review study was conducted at Henry Ford Health System (Detroit, MI, USA). Baseline demographics, bleeding events, treatment parameters, coexisting diseases, hemophilia-associated events, Charlson Comorbidity Index score, and prevalence of 12 cardiovascular risk factors and associated diseases were compared between hemophilia A and control cohorts...

PURPOSE: The aim of the study was to assess plasma RBP4 concentration in elderly subjects in relation to nutritional status and kidney function in the population of the PolSenior Study. MATERIAL AND METHODS: We assessed RBP4, glucose, insulin, albumin, lipid profile, C-reactive protein, (hsCRP) and creatinine concentrations in 2614 PolSenior Study participants (1235 women and 1379 men). The study group was divided based on BMI and HOMA-IR values, and the occurrence of diabetes...

PURPOSE: Human leukocyte antigen (HLA)-G is a non-classic major histocompatibility complex HLA class I molecule. HLA-G may have tolerogenic properties which are linked to epigenetic-sensitive pathways. There is a correlation of sHLA-G levels and graft acceptance in transplantation studies. There are previous data on correlation of sHLA-G with graft rejection as well as with viral infections such as hepatitis C virus (HCV) in kidney transplanted patients. Here, we report the sHLA-G expression in patients on the waiting list for kidney transplantation, with and without anti-HCV compared to a control group...

Pulmonary arterial hypertension is a multifactorial disease characterized by vasoconstriction, vascular remodeling, inflammation and thrombosis. Although an increasing number of research confirmed that pulmonary artery endothelial cells, pulmonary artery smooth muscle cells as well as platelets have a role in the pulmonary arterial hypertension pathogenesis, it is still unclear what integrates these factors. In this paper, we review the evidence that platelets through releasing a large variety of chemokines could actively impact the pulmonary arterial hypertension pathogenesis and development...

PURPOSE: Adaptation of the colorimetric method for the determination of β-d-galactosidase, β-d-glucuronidase and α-l-fucosidase activities in serums from hemolyzed blood, the material currently being discarded. MATERIALS AND METHODS: The materials included serums from hemolyzed and non-hemolyzed blood, obtained from 26 healthy volunteers. The adaptation of the method involved precipitation of the proteins with trichloroacetic acid after incubating serums with substrates, but before determining the products of enzymatic reactions...

MATERIAL AND METHODS: Twenty seven Polish healthcare facilities (HCFs) participated in this prospective study. Each HCF systematically sent all diarrhoeal stools received from inpatients at their laboratories on two days (one in January 2013 and one in July 2013), independently of CDI test request, to the National Coordinating Laboratory (NCL) for standardized testing of CDI...

Numerous reports on the interactions between the immune and endocrine systems, especially growth hormone axis, can be found in the literature. Growth hormone acts mainly indirectly through insulin-like growth factor-1, which stimulates the growth and development processes, metabolism of lipids, proteins, and carbohydrates, and it also has a modulating effect on the cells of the immune system. Several studies have been conducted on the influence of growth hormone therapy on the immunological parameters in children and adults with and without growth hormone deficiency...
