BACKGROUND: Active Vitamin D analogues are used clinically for prevention and treatment of secondary hyperparathyroidism (SHPT) in hemodialysis (HD) patients. Nutritional vitamin D supplementation is used for additional local parathyroid (PTH) suppression, with lower incidence of hypercalcemia and hyperphosphatemia. This study evaluates the possible beneficial effects of combined vitamin D treatment (paricalcitol and cholecalciferol). METHODS: Sixty HD patients with serum parathyroid hormone (iPTH) >300 pg/mL were enrolled...

We previously reported that the early vesicle of the palmoplantar pustulosis (PPP) vesicle originated from eccrine sweat in the acrosyringium, and that the PPP vesicle contains the antimicrobial peptide human cathelicidin (hCAP)-18/LL-37. The concentration of LL-37 was sufficient to induce the subsequent inflammation in lesions and human keratinocytes, and the PPP vesicles contained additional small fragments of hCAP-18, of ∼7 kDa, which have not been identified. The aim of the present study was to clarify the additional processed forms found in PPP vesicles and their physiological effects on normal keratinocytes and sweat gland cells...

The current work exploits the effective application of thermoluminescence (TL), optically stimulated luminescence (OSL) and the possibility of applying Electron Paramagnetic Resonance (EPR) for the discrimination between different bioactive responses in the case of the 45S5 bioactive glass (SiO2 45, Na2O 24.5, CaO 24.5, P2O5 6 in wt%), which was synthesized through melting process. These techniques are suggested mainly due to their low spectroscopic detection thresholds. The original 45S5 in grain size range of 20-40μm was immersed in the Simulated Body Fluid (SBF) for various different immersion times ranging over one week...

The traditional Chinese medicine Chan-Su is widely used for treatment of cancer and cardiovascular diseases, but also as a remedy for infections such as furunculosis, tonsillitis and acute pharyngitis. The clinical use of Chan-Su suggests that it has anti-infective effects, however, the mechanism of action is incompletely understood. In particular, the effect on the human immune system is poorly defined. Here, we describe previously unrecognized immunomodulatory activities of cinobufagin (CBG), a major bioactive component of Chan-Su...

BACKGROUND: After the concept of healthcare associated pneumonia (HCAP) was introduced in 2005 by the American Thoracic Society/Infectious Disease Society of America (ATS/IDSA), pneumonia in hemodialysis patients has been classified as HCAP. Even though there are several risk factors and scoring systems of drug-resistant pathogens (DRPs) in HCAP, the risk factors for DRPs in hemodialysis-associated pneumonia are unclear. METHODS: Patients who were admitted to our tertiary care hospital from January 2005 to December 2010 were screened by a discharge diagnosis of pneumonia...

The biologically active form of vitamin D, 1α,25-dihydroxyvitamin D3 (1,25D3), has been reported to positively regulate the human cathelicidin anti-microbial peptide (CAMP) gene coding for LL-37, but the mechanisms are not completely understood. We have determined the expression of CAMP, vitamin D receptor (VDR), and the retinoid X receptor (RXR) isoforms in human skin and gingival tissue biopsies and investigated the signaling pathways involved in 1,25D3-induced upregulation of CAMP. Human skin and gingival biopsies exhibited few VDR-immunoreactive cells within the stratum basale, whereas rat colon enterocytes (positive control) possessed abundant VDR immunoreactivity...

Maxacalcitol (22-oxacalcitriol: OCT) is a synthetic vitamin D3 analog with a limited calcemic effect. In this study, we investigated whether OCT increases the production of LL-37/CAP-18, a human cathelicidin antimicrobial peptide, in human gingival/oral epithelial cells. A human gingival epithelial cell line (Ca9-22) and human oral epithelial cell lines (HSC-2, HSC-3, and HSC-4) exhibited the enhanced expression of LL-37 mRNA upon stimulation with OCT as well as active metabolites of vitamins D3 and D2. Among the human epithelial cell lines, Ca9-22 exhibited the strongest response to these vitamin D-related compounds...

Community acquired pneumonia (CAP) is an infection with a limited spectrum of pathogens. Pneumonias acquired in a hospital or under immunoincompetence are being treated according to different algorithms. The concept of health care associated pneumonia (HCAP) is discarted. It is not capable to predict a high probability of multiresistant pathogens.
