Common variable immunodeficiency (CVID) is the commonest from of primary immunodeficiency characterized by antibody deficiency, recurrent bacterial infections and autoimmunity. Advanced chronic liver disease occurs in a subset of patients with CVID and manifests with various histological features such as nodular regenerative hyperplasia, inflammation, fibrosis and cholangiopathy. We present a case series characterizing the outcomes in adult patients transplanted for primary CVID-related liver disease. We discuss the unique transplantation challenges faced in this primary immunodeficiency group including susceptibility to infections and early disease recurrence...

Hepatitis B virus (HBV) reactivation becomes a challenging issue with increasing use of immunosuppressive agents and cytotoxic chemotherapy for varied medical conditions, including cancer. The spectrum of HBV reactivation in the setting of immunosuppression may vary from asymptomatic reactivation to liver failure leading to death. HBV reactivation can hamper the course of planned therapies and diminish the effects of therapies; thus, it adversely affects the prognosis of the original disease and the survival of the patients...

Hepatitis E virus (HEV) infection can lead to acute and chronic hepatitis as well as to extrahepatic manifestations such as neurological and renal disease; it is the most common cause of acute viral hepatitis worldwide. Four genotypes are responsible for most infection in humans, of which HEV genotypes 1 and 2 are obligate human pathogens and HEV genotypes 3 and 4 are mostly zoonotic. Until quite recently, HEV was considered to be mainly responsible for epidemics of acute hepatitis in developing regions owing to contamination of drinking water supplies with human faeces...

OBJECTIVE: We examined the treatment patterns among adults with rheumatoid arthritis (RA) and identified factors influencing access to traditional and biological disease modifying antirheumatic drugs (DMARDs). METHODS: We analyzed visits recorded in the National Ambulatory Medical Care Survey from 2005 to 2014 with a RA diagnosis. The primary outcome was DMARD use (traditional and/or biological). We included prescriptions of all RA-related treatments such as traditional and biological DMARDs, glucocorticoids, gold preparations, immunosuppressants, and non-steroidal anti-inflammatory drugs...

Renal dysfunction caused by calcineurin inhibitor (CNI) nephrotoxicity occurs often and contributes significantly to late mortality after heart transplantation (HTx). Over the last decades, this has prompted many clinical studies in an effort to develop kidney-protecting immunosuppressive strategies including delayed CNI start, minimization, withdrawal or even de-novo CNI avoidance. In the past, these strategies often failed due to the lack of efficacy. Since 2009, novel CNI-reducing strategies are under investigation...

Tumor cell chemoresistance is a major challenge in cancer therapeutics. Major select metal-based drugs are potent anticancer agents yet they exhibit undesirable side-effects and are effective against only a few types of cancers. A need, therefore, arises for new metallodrugs with an improved spectrum of efficacy and lower toxicity. Development of anticancer drugs based on antitumor metals is currently a very active field, with considerable efforts having been made toward elucidating the mechanisms of immune action of complex metalloforms and optimizing their immunoregulatory bioactivity through appropriate structural modification...

Current strategies for treating autoimmunity involve the administration of broad-acting immunosuppressive agents that impair healthy immunity. Intravenous (i.v.) administration of poly(lactide-co-glycolide) nanoparticles (NPs) containing disease-relevant antigens (Ag-NPs) have demonstrated antigen(Ag)-specific immune tolerance in models of autoimmunity. However, subcutaneous (s.c.) delivery of Ag-NPs has not been effective. This investigation tested the hypothesis that co-delivery of the immunomodulatory cytokine, transforming growth factor beta 1 (TGF-β), on Ag-NPs would modulate the immune response to Ag-NPs and improve the efficiency of tolerance induction...

Primary nephrotic syndrome (NS) is the most common glomerular disease in children. It is characterized by massive proteinuria and hypoalbuminemia. It typically has a sudden onset and more than 70% of patients will experience at least one relapse. An immunological origin has long been postulated, although the precise molecular mechanisms underlying the disease remain debated. Steroids are the first-line therapy with cumulative dose and duration of initial treatment varying among countries. Steroid-sparing agents may be indicated in case of steroid-dependency or frequent relapses...

Gangrenous dermatitis (GD) is a disease of chickens and turkeys that causes severe economic losses in the poultry industry worldwide. Clostridium septicum, Clostridium perfringens type A, and occasionally Clostridium sordellii are considered the main causes of GD, although Staphylococcus aureus and other aerobic bacteria may also be involved in some cases of the disease. GD has become one of the most significant diseases of commercial turkeys in the United States. Several infectious and/or environmental immunosuppressive factors can predispose to GD...

Previous research indicated the association between hepatitis B virus (HBV) infection/vaccination and the onset of demyelinating diseases. However, most of these studies were single case reports, and comprehensive data are still scarce. Here we present a comprehensive analysis of 10 patients with neuromyelitis optica spectrum disorder (NMOSD) combined with chronic hepatitis B (CHB) infection and seropositive for anti-aquaporin-4 antibody (AQP4-Ab). Demographic, clinical, laboratory, neuroimaging, outcome, and follow-up data of the 10 patients were retrospectively analyzed...

Chronic uveitis is a common extra-articular manifestation of juvenile idiopathic arthritis. The classic clinical picture is one of chronic anterior uveitis, which usually remains asymptomatic until ocular complications arise. The risk of uveitis is increased in girls with an early onset of oligoarthritis and positive antinuclear antibodies. Even though the inflammation in patients with juvenile idiopathic arthritis is initially limited in the anterior part of the eye, chronic active inflammation may eventually cause significant damage to the posterior pole...

Neuromyelitis Optica Spectrum Disorder (NMOSD) is a relapsing neuro inflammatory disease of the central nervous system that typically presents with optic neuritis or myelitis and may cause severe disability. The diagnostic criteria have been updated and several immunosuppressive agents have been demonstrated to prevent acute exacerbations. As the disease rarely develops in a progressive course, management of acute attacks and proper prevention of exacerbations may change the long term out-come and prevent future disability...

Multiple Sclerosis (MS) is an autoimmune disease in which lymphocytes target putative myelin antigens in the CNS, causing inflammation and neurodegeneration. Fingolimod (FTY720) is an immunosuppressive drug used as a second line therapy for relapsing forms of MS due to its safety profile and good response to treatment. Despite its safety, there are still concerns about the possibility of Fingolimod being linked to the development of opportunistic infections like disseminated varicella zoster infections and herpes simplex encephalitis...

BACKGROUND: Chronic disseminated candidiasis (CDC) is a severe invasive fungal infection principally observed during neutrophil recovery in patients with acute leukemia treated with intensive chemotherapy. Its pathophysiology remains unclear. We describe the management of six children with symptomatic CDC who did not respond to antifungal therapy. METHODS: The databases of the hematology-oncology departments of two tertiary pediatric medical centers were searched for all patients diagnosed with CDC from 2003 to 2015 who responded to corticosteroids after failing antifungal therapy...

Autoimmune hepatitis is an uncommon idiopathic syndrome of immunemediated destruction of hepatocytes, typically associated with autoantibodies. The disease etiology is incompletely understood but includes a clear association with human leukocyte antigen (HLA) variants and other non- HLA gene variants, female sex, and the environment. Pathologically, there is a CD4+ T cell-rich lymphocytic inflammatory infiltrate with variable hepatocyte necrosis and subsequent hepatic fibrosis. Attempts to understand pathogenesis are informed by several monogenetic syndromes that may include autoimmune liver injury, by several drug and environmental agents that have been identified as triggers in a minority of cases, by human studies that point toward a central role for CD4+ effector and regulatory T cells, and by animal models of the disease...

Treatment of patients with hepatocellular carcinoma in the advanced stage remains a great challenge, with very few drugs approved. After decades of failures of immune therapies, immune checkpoint inhibitors have emerged as potentially effective treatments for patients with hepatocellular carcinoma in the advanced stage. Immune checkpoints, including human cancer, cytotoxic T-lymphocyte protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1), are surface proteins expressed in a variety of immune cells, and mostly provide immunosuppressive signals...

Tacrolimus (FK506) is a chemotherapeutic agent, which uses calcineurin pathway via inhibiting the stimulation of T cells to prevent the formation of immune response in the recipient individual in organ transplants. FK506 is mainly metabolized in the liver by cytochrome P450 enzyme system and is known that it has high toxic effects on different cells. Mesenchymal stem cells (MSCs) have recently gained importance since their potential to be used in cellular therapy and tissue regeneration. In some clinical cases, MSCs are transferred into the patient after the organ transplantations in order to support the treatment...

Hydroxychloroquine (HCQ) is an immunosuppressive agent widely used in rheumatoid arthritis (RA). T follicular helper (Tfh) cells play a vital role in the pathogenesis of RA. However, whether HCQ suppresses arthritis development through interfering with Tfh cells have never been reported. To address this issue, we investigated the percent of Tfh cells in newly diagnosed RA patients and found that they were up-regulated in peripheral blood. Importantly, in ex vivo experiments of peripheral blood mononuclear cells (PBMCs) from healthy volunteers, we proved that the percentage of Tfh cells in PBMCs and purified CD4(+) T cells were decreased after HCQ treatment...
