Isolated invasive Mucormycosis of the parotid gland is rarely reported in the literature (1). Mucormycosis most commonly manifests as rhino-oculocerebral and pulmonary infections in the patients with altered immunity (uncontrolled Diabetes mellitus, recipients of immunosupressive therapy and underlying hematological malignancies) (2). Rarely, it causes infection in the immunocompetent individuals (3) with the involvement of unusual sites like gastrointestinal tract, ear, soft tissue and skin (4, 5).

Currently, Systemic Lupus Erythematosus (SLE) therapies range from antimalarials to glucocorticoids, in addition to immunosupressive agents or biologics such as rituximab or belimumab, when needed. Several unmet needs remain in the treatment SLE and more targeted drugs with improved safety profiles are expected. Based on recent advances in the understanding of the complex pathogenesis of SLE, several targeted treatments are currently assessed in clinical trials. In this study, we performed a systematic review of all targeted therapies under clinical development in SLE in 17 online registries of clinical trials...

Gyrodactylus cichlidarum and Cichlidogyrus sclerosus, two monogenean ectoparasite species commonly found on the body surface and gills of Nile tilapia (Oreochromis niloticus) respectively, inflicted considerable economic losses in intensive tilapia farming. In order to explore the immune response of tilapia against these two species of monogeneans, expression patterns of five immune-related genes were studied after singular G. cichlidarum or C. sclerosus infection and their coinfection. The transcription levels of IL-1β were up-regulated in the skin after G...

OBJECTIVE: Autoimmune hepatitis (AIH) is an inflammatory disease caused by aberrant immune response to hepatic self-antigens in which regulatory T cells (Tregs) are critical to maintain immunosupression. Soluble form of Fibrinogen-like protein 2 (sFGL2), a novel effector molecule of Treg is rarely investigated in AIH. Here, we dissected the role of sFGL2 in the autoimmune hepatitis and its potential mechanism underlying AIH progression. METHODS: Plasma and intrahepatic sFGL2 levels, as well as Treg cells were measured in both AIH patients and experimental autoimmune hepatitis (EAH) mice...

The prototypic proinflammatory cytokine IL-1β plays a central role in innate immunity and inflammatory disorders. The formation of mature IL-1β from an inactive pro-IL-1β precursor is produced via nonconventional multiprotein complexes called the inflammasomes, of which the most common is the nucleotide-binding domain leucine-rich repeat-containing protein 3 (NLRP3) inflammasome composed by NLRP3, (ASC) apoptosis-associated speck-like protein containing a caspase activation and recruitment domain (CARD), and caspase-1...

Hepatology played an important role in ESPGAN from the beginning. In 1989, the Hepatology Committee was started. In the early 1990s H for hepatology was included in ESPGHAN. Hepatology Summer schools were held from 1995 and later monothematic conferences met the needs of many young ESPGHAN members. The role of ESPGHAN members in the progress of diagnostic and therapeutic measures in hepatitis B and C will be elucidated (Chapter 6.1) as well as the role of other ESPGHAN members in the understanding of immunological hepatic disorders of childhood (Chapter 6...

Systemic sclerosis is classed as a diffuse (systemic) disease of connective tissue. It is a heterogeneous disease significantly shortening life expectancy. Its etiology is unknown. Pathogenetic interplay is assumed to involve a triad of pathological autoimmune inflammation, vasculopathy and fibrosis. Clinical manifestations can be classed based on the preponderant pathogenetic process. Vasculopathy is manifested by secondary Raynauds phenomenon with abnormal findings on the nailfold capillaroscopy, skin telangiectasias, gastric antral vascular ectasia, life threatening scleroderma renal crisis, digital ulcerations and prognostically severe pulmonary arterial hypertension...

Solid organ transplantation is the treatment of choice for patients with end-stage organ dysfunction. Despite improvements in short-term outcome, long-term outcome is suboptimal due to the increased morbidity and mortality associated with the toxicity of immunosuppressive regimens and chronic rejection (1-5). As such, the attention of the transplant community has focused on the development of novel therapeutic strategies to achieve allograft tolerance, a state whereby the immune system of the recipient can be re-educated to accept the allograft, averting the need for long-term immunosuppression...

INTRODUCTION: In prior small animal studies, we maintained vascularized bone allotransplant viability without long-term immunotherapy. Instead, an autogenous neoangiogenic circulation is created from implanted vessels, sufficient to maintain bone viability with only 2 weeks immunosupression. Blood flow is maintained despite rejection of the allogeneic vascular pedicle thereafter. We have previously described a large animal (swine) pre-clinical model, reconstructing tibial defects with vascularized tibial allotransplants...

Two purified polysaccharides named WPMP-1 and WPMP-2 were obtained from Polygonum multiflorum with an average molecular weight of 2.04kDa and 92.13kDa, respectively. Structural characterization revealed that WPMP-1was supposed to be a glucan composed of 1,4-linked α-d-Glcp, 1,4,6-linked α-d-Glcp, and terminal α-d-Glcp. WPMP-2 contained a complex branched structre formed by 1,2-linked α-d-Rhap, 1,2,4-linked α-d-Rhap, 1,3,5-linked α-l-Ara, 1,5- linked α-l-Araf, terminal α-l-Araf, 1,4-linked β-d-Galp, 1,4-linked α-d-GalpA, and 4-linked α-d-GalpA...

INTRODUCTION: Recent animal studies demonstrated immunosuppressive effects of opioid withdrawal resulting in a higher risk of infection. The aim of this study was to determine the impact of remifentanil discontinuation on Post-Anesthesia Care Unit (PACU)-acquired infection after a schedule of sedoanalgesia of at least 6 days. METHOD: All patients over 18 years of age with a unit admission of more than 4 days were consecutively selected. The study population was the one affected by surgical pathology of any origin where sedation was based on any hypnotic and the opioid remifentanil was used as analgesic for at least 96 hours in continuous perfusion...

A presence of mycotoxins in feed is one of the most alarming issues in the poultry feed industry. Ochratoxins, produced by several Aspergillus and Penicillium species, are important mycotoxin regarding the health status of poultry birds. Ochratoxins are further classified into to several subtypes (A, B, C, etc) depending on their chemical structures, but ochratoxin A (OTA) is considered the most important and toxic. Bentonite clay, belonging to phyllosilicates and formed from weathering of volcanic ashes, has adsorbent ability for several mycotoxins...

Opportunistic fungal infections like invasive candidiasis and aspergillozis have high mortality rate particularly in immunosupressive patients. The rate of therapy success with antifungal agents is usually low. Although immunotherapy methods have been developed to increase the host response against antifungals, there has been a need for new antifungal therapeutic agents in the treatment of invasive aspergillozis and other opportunistic fungal infections. Mycoviruses are the viruses that specifically infect fungi...

Magnusiomyces capitatus is an emerging opportunistic fungal pathogen particularly in immunocompromised patients. We report a case of a M. capitatus peritonitis in child with acute lymphocytic leukemia as a breakthrough infection during caspofungin therapy. The possibility of breakthrough infections caused by M. capitatus must be taken into consideration, particularly in immunosupressed patients being treated for systemic fungal infections by caspofungin. Although there are no defined breakpoints for susceptibility testing of M...

MYH9-related disorders (MYH9-RDs) caused by mutation of the MYH9 gene which encodes non-muscle myosin heavy-chain-IIA (NMMHC-IIA), an important motor protein in hemopoietic cells, are the most commonly encountered cause of inherited macrothrombocytopenia. Despite distinguishing features including an autosomal dominant mode of inheritance, giant platelets on the peripheral blood film accompanied by leucocytes with cytoplasmic inclusion bodies (döhle-like bodies), these disorders remain generally under-recognized and often misdiagnosed as immune thrombocytopenia (ITP)...
