BACKGROUND: Primary immune thrombocytopenia is a severe bleeding disorder. About 50-85% of patients achieve initial remission from first-line therapies, but optimal second-line treatment remains a challenge. All-trans retinoic acid (ATRA) has an immunomodulatory effect on haemopoiesis, making it a possible treatment option. We aimed to evaluate the efficacy and safety of ATRA plus danazol versus danazol in non-splenectomised patients with corticosteroid-resistant or relapsed primary immune thrombocytopenia...

MEDI-570 is a fully human afucosylated monoclonal antibody (MAb) against Inducible T-cell costimulator (ICOS), highly expressed on CD4+ T follicular helper (TFH) cells. Effects of MEDI-570 were evaluated in an enhanced pre-postnatal development toxicity (ePPND) study in cynomolgus monkeys. Administration to pregnant monkeys did cause any abortifacient effects. Changes in hematology and peripheral blood T lymphocyte subsets in maternal animals and infants and the attenuated infant IgG immune response to keyhole limpet hemocyanin (KLH) were attributed to MEDI-570 pharmacology...

BACKGROUND: Abdominal aortic aneurysms (AAA) are a major source of morbidity and mortality despite continuing advances in surgical technique and care. Although the inciting factors for AAA development continue to be elusive, accumulating evidence suggests a significant peri-aortic inflammatory response leading to degradation and dilation of the aortic wall. Previous human trials have demonstrated safety and efficacy of mesenchymal stem cells (MSCs) in the treatment of inflammation-related pathologies such as rheumatoid arthritis, graft vs host disease, and transplant rejection...

Purpose The addition of nivolumab (anti-programmed death-1 antibody) to ipilimumab (anti-cytotoxic T-cell lymphocyte-associated 4 antibody) in patients with advanced melanoma improves antitumor response and progression-free survival but with a higher frequency of adverse events (AEs). This cross-melanoma study describes the safety profile of the approved nivolumab plus ipilimumab regimen. Methods This retrospective safety review on data from three trials (phase I, II, and III) included patients with advanced melanoma who received at least one dose of nivolumab 1 mg/kg plus ipilimumab 3 mg/kg every 3 weeks × 4 and then nivolumab 3 mg/kg every 2 weeks until disease progression or unacceptable toxicity while following established guidelines for AE management...

BACKGROUND: While there are guidelines for the use of intravenous immunoglobulins in children with Guillain-Barre syndrome and myasthenia gravis based on high-level evidence studies, data is fewer for the majority of neurologic disorders in this age group. Neuronal antibodies are detected in children with seizures of autoimmune etiology. Intravenous immunoglobulins with their broad immunomodulatory mechanism of action could be ideally effective in different forms of immune-dysregulated intractable epilepsies such as autoimmune epilepsy and autoimmune Rasmussen encephalitis...

BACKGROUND: Surgical site infections (SSI) are one of the most common complications after hepato-pancreato-biliary surgery. Infectious complications may lead to an associated immune-modulatory effect that inhibits the body's response to cancer surveillance. We sought to define the impact of SSI on long-term prognosis of patients undergoing surgical resection of extrahepatic biliary malignancies (EHBM). METHODS: Patients undergoing surgery for EHBM between 2000 and 2014 were identified using a large, multi-center, national cohort dataset...

Immune checkpoint inhibitors (ICIs) are becoming a standard therapy for non-small-cell lung cancer in the advanced stage. As these ICIs become widely available in clinical practice, immune-related adverse effects will become more common. Here we report a patient with lung adenocarcinoma who was treated with nivolumab and developed obstruction because of biliary inflammation. A 63-year-old Japanese man having lung adenocarcinoma with pleural dissemination complained of epigastric pain on the fifth cycle of nivolumab...

PURPOSE: Vitamin D may induce tolerance in the intestinal immune system and has been shown to regulate the phenotype of tolerogenic intestinal dendritic cells (DCs) in vitro. It is unknown whether vitamin D supplementation affects human intestinal DCs in vivo, and we aimed to investigate the tolerability and effect on intestinal CD103(+)DCs of high-dose vitamin D3 treatment in healthy subjects. METHODS: Ten healthy subjects received a total of 480,000 IU oral vitamin D3 over 15 days and colonic biopsies were obtained before and after intervention by endoscopy...

Resolution agonists, including lipid mediators and peptides such as annexin A1 (ANXA1), are providing novel approaches to treat inflammatory conditions. Surgical trauma exerts a significant burden on the immune system that can affect and impair multiple organs. Perioperative cerebral injury after cardiac surgery is associated with significant adverse neurological outcomes such as delirium and postoperative cognitive dysfunction. Using a clinically relevant rat model of cardiopulmonary bypass (CPB) with deep hypothermic circulatory arrest (DHCA), we tested the pro-resolving effects of a novel bioactive ANXA1 tripeptide (ANXA1sp) on neuroinflammation and cognition...

Cancer immunotherapy are taking a leading role of cancer therapy due to the development of the immune checkpoint blockade. To date, however, only about 20% of patients have clinical responses and the cancer-specific T cells in cancer site are required to obtain beneficial effects. There has been an innovative development in the field of adoptive cell therapy, especially receptor gene-modified T cells in recent years. The effector cells mostly express PD-1, therefore the cytotoxic reactivity of the effector cells are inhibited by PD-L1...

The mitogen-activated protein kinases (MAPKs) are fundamental in inflammation and cancer control, through the crosstalk between the redox regulated nuclear factor E2-related factor 2 (Nrf2) and nuclear factor-kB (NFκB) gene expression. MAPKs regulate various cellular activities involved in cancer progression, including proliferation, apoptosis and immune escape and blockade of upstream kinases is a current therapeutic strategy. However, these therapies are associated with some adverse effects and with the paradoxical activation of the MAPKs pathway...

Dysregulation of the endogenous lipid mediators endocannabinoids and their G-protein-coupled cannabinoid receptors 1 and 2 (CB1R and CB2R) has been implicated in a variety of cardiovascular pathologies. Activation of CB1R facilitates the development of cardiometabolic disease, whereas activation of CB2R (expressed primarily in immune cells) exerts anti-inflammatory effects. The psychoactive constituent of marijuana, Δ(9)-tetrahydrocannabinol (THC), is an agonist of both CB1R and CB2R, and exerts its psychoactive and adverse cardiovascular effects through the activation of CB1R in the central nervous and cardiovascular systems...

Psoriasis is a chronic inflammatory and immune-mediated skin disease. The pathogenesis involves T cells activation via the IL-23/Th17 axis. Conventional treatments of psoriasis have adverse events influencing patients' adherence. Wannachawee Recipe (WCR) has been effectively used as Thai folk remedy for psoriasis patients; however, preclinical evidence defining how WCR works is still lacking. This study defined mechanisms for its antiproliferation and anti-inflammatory effects in HaCaT cells. The cytotoxicity and antiproliferation results from SRB and CCK-8 assays showed that WCR inhibited the growth and viability of HaCaT cells in a concentration-dependent manner...

While trimethoprim-sulfamethoxazole is considered first-line therapy for Pneumocystis pneumonia prevention in renal transplant recipients, reported adverse drug reactions may limit use and increase reliance on costly and less effective alternatives, often aerosolized pentamidine. We report our experience implementing a protocolized approach to trimethoprim-sulfamethoxazole adverse drug reaction assessment and rechallenge to optimize prophylaxis in this patient cohort. We retrospectively reviewed 119 patients receiving Pneumocystis pneumonia prophylaxis prior to and after protocol implementation...

Probiotics have been defined as live microorganisms which, when ingested in adequate numbers, confer health benefits to the host. They are currently consumed without any age restrictions and adverse effects such as sepsis, a marker of the risk of invasion of the bloodstream, are extremely infrequent. However, some health professionals express doubts about probiotics being truly innocuous. This review discusses the incidence of sepsis secondary to probiotics use, mainly lactobacilli and bifidobacteria, evaluated through molecular biology or classic culture techniques, showing that sepsis in large numbers of individuals along decennia is extremely low, of the order of 0,02% en some centers or as low as 1 case/million population in France...

Recent advances in understanding the molecular mechanisms of cancer have opened a new era of precision medicine for cancer treatment. Precision cancer therapies target specific molecules that are responsible for cancer development and progression, and they achieve marked treatment benefits in specific cohorts of patients. However, these therapies are also associated with a variety of complications that are often unique to specific groups of anticancer agents. The rapidly increasing use of immune checkpoint inhibitors in the treatment of various advanced malignancies has brought new challenges in diagnosing and monitoring a unique set of toxic effects termed immune-related adverse events...
