Therefore, a role of non-cellular components in the epidermal antifungal defence was suggested. To investigate the presence of such factors in these infections, the expression of human beta defensins 2 and 3 (hBD-2, hBD-3), RNase 7, psoriasin, toll-like receptors 2, 4 and 9 (TLR2, TLR4

and TLR9) and dectin 2 was analysed by use of immunostainings in skin biopsies. We found that hBD2, hBD3, psoriasin, Ulixertinib RNase7, TLR2 and TLR4 were significantly more often expressed in distinct layers of lesional epidermis as compared with uninfected epidermis. In both infections but not in normal skin, hBD2 and hBD3 were commonly expressed within the stratum corneum and in the stratum granulosum. Similarly, psoriasin was seen more often in the upper skin layers of both infections as compared with normal skin. No significant differences between normal and infected skin were found for

the expression of TLR9 and dectin 2. Our findings clearly show DNA Damage inhibitor the expression of specific antimicrobial proteins and defence-related ligands in superficial tinea as well as in pityriasis versicolor, suggesting that these factors contribute to fungal containment. “
“Although the consequences of invasive fungal infections (IFIs) secondary to chronic hepatitis B infections secondary IFIs are serious, the incidence and main pathogenic factors of IFIs in acute-on-chronic liver failure (ACLF) patients remain unclear. This study included 1200 Inositol monophosphatase 1 hepatitis B patients who were treated in the Department of Infectious Diseases, Shanghai Changzheng Hospital from January 2006 to January 2009. Patients with ACLF were screened according to the diagnostic guidelines for liver failure. Patients with ACLF and secondary IFI were the disease group, and patients with ACLF without secondary IFI were the controls. The incidence of IFI, mortality, and possible IFI causes in two groups

were evaluated retrospectively. Sixty patients with ACLF had secondary IFI, of which 14 were confirmed cases and 46 were suspected cases. The incidence of IFI was 47.62% for ACLF patients. Logistic regression analysis showed that the level of hepatitis B viral (HBV) DNA was an important risk factor for secondary IFI in ACLF patients. Receiver operating characteristic curve analysis suggested that when the number of HBV DNA copies was higher than 3.16 × 103 copies ml−1, the possibility of secondary IFI in ACLF patients increased significantly, while white blood cell levels showed protective effects for these patients. The incidence of IFI is high in ACLF patients and high hepatitis B virus DNA levels may be an independent risk factor of secondary IFI in these patients. “
“A total of 165 sporotrichosis cases occurring in Nagasaki prefecture, and examined at Nagasaki University Hospital, were evaluated.
