The global variation in type 1 diabetes (T1D) incidence rates is one of the most significant observed for any non-communicable disease. Geographical patterns in incidence suggest that low sun exposure may contribute to the wide disparity, with incidence rates generally increasing with distance from the Equator. T1D development is associated with hyperactivity of the adaptive immune system leading to autoimmune destruction of insulin-secreting pancreatic β cells. Both exposure to ultraviolet radiation (UVR) and vitamin D, with their known immunosuppressive effects, have the potential to delay or inhibit the disease...

Programmed cell death-1 (PD-1) and its ligands, PD-L1 and PD-L2, have been regarded as important immune system regulatory molecules. The aberrant expression of the molecules has been related to several autoimmune disorders. This study is aimed to assess the mRNA expression level of PD-1, PD-L1, and PD-L2 molecules in the peripheral blood mononuclear mells (PBMCs) from multiple sclerosis (MS) patients. PBMCs were isolated from the whole blood of 50 MS and 50 healthy individuals. Total RNA content of the leukocytes was extracted...

Small intestinal bleeding in Crohn's disease patients with noncirrhotic portal hypertension and partial portal and superior mesenteric vein thrombosis is a life-threatening event. Here, a case is reported in which treatment with azathioprine may have resulted in nodular regenerative hyperplasia, portal hypertension and portal vein thrombosis. The 56-year-old patient with Crohn's disease developed nodular regenerative hyperplasia under treatment with azathioprine. He was admitted with severe bleeding. Gastroscopy showed small esophageal varices without bleeding stigmata...

Many antihypertensive agents have been demonstrated to assist in preservation of kidney function, among them those that modulate calcium channels. Calcium channel blockers may also be of value in protecting hemodialysis patients from complications of sepsis. In diabetic recipients of kidney transplant allografts treated with cyclosporine, calcium channel blockade has been retrospectively linked to improved graft preservation and to fewer episodes of sepsis. This brief review outlines clinical and experimental publications on potential protection from sepsis by addition of calcium channel blockers to standard antibiotic therapy in individuals who may or may not have normal kidney function, or in the presence or absence of immunosuppression...

Researchers have figured out a way to switch the immunosuppressive phenotype of tumor-associated macrophages to one that's immunostimulatory. By inhibiting PI3Kγ in these macrophages, they significantly suppressed tumor growth in mice; when anti-PD-1 therapy was added to PI3Kγ inhibition, complete and sustained tumor eradication was observed in many cases.

Immune cells constitute a large fraction of the tumor microenvironment and modulate tumor progression. Clinical data indicate that chronic inflammation is present at tumor sites and that IL4 in particular is upregulated. Here we demonstrate that T follicular helper (Tfh) cells arise in tumor-draining lymph nodes where they produce an abundance of IL4. Deletion of IL4-expressing Tfh cells improves antitumor immunity, delays tumor growth, and reduces the generation of immunosuppressive myeloid cells in the LNs...

PD-1/PD-L1 pathway is a negative regulator of immune activation that is up-regulated in multiple myeloma and is a critical component of the immunosuppressive tumor microenvironment. Expression is increased in advanced disease and in the presence of bone marrow stromal cells. PD-1/PD-L1 blockade is associated with tumor regression in several malignancies but single agent activity is limited in myeloma patients. Combination therapy involving strategies to expand myeloma specific T cells and T cell activation via PD-1/PD-L1 blockade are currently being explored...

Immune mediated necrotizing myopathy (IMNM) is an acquired inflammatory myopathy. One form of the disease is associated with serum anti-HMGCR autoantibodies and significant proportion of patients has a history of statin treatment. The disease is rare with the incidence estimated around 23 cases/100 000 statin treated individuals. In contrast to direct statin toxicity, anti-HMGCR associated IMNM is an induced autoimmune disease.Patients suffer particularly from severe muscle weakness, which may be occasionally totally immobilizing...

Patients with inflammatory bowel disease (IBD) are not vaccinated at the same rate as general medical patients. IBD places patients at increased risk for developing vaccine-preventable illnesses, and this risk is further exacerbated by immunosuppressive therapy. Therefore, gastroenterologists should familiarize themselves with health maintenance measures pertaining to patients with IBD. This article highlights the vaccinations required for patients with IBD, especially those who are immunosuppressed: influenza; pneumococcal pneumonia; hepatitis A and B viruses; human papilloma virus; meningococcal disease; tetanus, diphtheria, and pertussis; measles, mumps, and rubella; varicella zoster; and herpes zoster...

Improved short- and long-term survival of liver transplant recipients has led to increased focus on complications of both the early and late posttransplant periods. A variety of metabolic complications have been observed in the post-orthotopic liver transplant population, including hypertension, hyperlipidemia, obesity, diabetes mellitus, nonalcoholic fatty liver disease, and nonalcoholic steatohepatitis. Although only a small proportion of patients experience metabolic complications prior to transplantation, the prevalence of these complications posttransplantation reaches or exceeds that of the general population...

Generalized pustular psoriasis appears as an uncommon variant form of psoriasis consisting of widespread pustules on an erythematous background (von Zumbusch). A 39-year-old male patient with a history of plaque psoriasis since the age of 9 who had an acute relapse of generalized pustular psoriasis 12 days following a successful renal transplantation is presented. Despite administered immunosuppression for transplantation, the addition of cyclosporine and methotrexate did not reverse the ongoing process of disease and the patient died on the 57th posttransplant day due to multiorgan failure subsequent to severe bone marrow suppression...
