Drug-induced diabetes is one of the factors contributing to the increasing incidence of diabetes worldwide. This review considers the frequency, pathogenesis and treatment of drug-induced diabetes. Drugs that induce diabetes include hormonal therapy, especially glucocorticoids and androgen blockers, cardiovascular drugs, especially statins, beta-blockers and diuretics, antipsychotics, especially clozapine, olanzapine and quetiapine, antiretrovirals (protease inhibitors and non-reverse transcriptase inhibitors - NRTIs) and other drugs (mechanistic target of rapamycin inhibitors -mTORs, post organ transplantation drugs, tyrosine kinase inhibitors and interferon-alpha)...

MicroRNA-22 (miR-22) is a highly conserved microRNA that can regulate cell proliferation, oncogenesis, and cell maturation, especially during stress. In hematopoietic stem cells (HSCs) miR-22 has been reported to be involved in the regulation of key self-renewal factors including Tet2. Recent work demonstrates that miR-22 also participates in regulation of the interferon response, and expression profiling studies suggest that it is variably expressed at different stages in erythroid differentiation. We thus hypothesized that miR-22 regulates maturation of erythroid progenitors during stress hematopoiesis through its interaction with interferon...

BACKGROUND: Corticosteroid sparing is required in 15% to 40% of adults with persistent or chronic primary immune thrombocytopenic purpura (ITP). Herein, the efficacy of immunomodulatory drugs (dapsone, interferon alpha, danazol, and hydroxychloroquine as second-third-line therapies in ITP is investigated. METHODS: MEDLINE was searched for studies that included patients with persistent or chronic primary ITP and published before the end of December 2014. Two investigators independently extracted data regarding study design, patient characteristics, dosage schedule, time to response, and occurrence of adverse events...

Giant cell tumor (GCT) of bone is a locally aggressive benign neoplasm that is associated with a large biological spectrum ranging from latent benign to highly recurrent and occasionally metastatic malignant bone tumor. It accounts for 4-10% of all bone tumors and typically affects the meta-epiphyseal region of long bones of young adults. The most common site involved is the distal femur, followed by the distal radius, sacrum, and proximal humerus. Clinical symptoms are nonspecific and may include local pain, swelling, and limited range of motion of the adjacent joint...

The use of systematic approach for the analysis of mechanism of action of drugs at different levels of biological organization of organism is an important task in experimental and clinical pharmacology for drug designing and increasing the efficacy and safety of drugs. The analysis of published data on pharmacological effects of psychotropic drugs possessing immunomodulatory and/or antiviral properties have shown a correlation between central effects of examined drugs associated with the impact on the processes of neurogenesis of mature brain and survival of neurons, and their ability to alter levels of key proinflammatory cytokines...

BACKGROUND: Dual therapy (PegIFN and ribavirin) (DT) had been the standard of care in patients infected with HCV genotype 4 (HCV-4) until 2014. Thereafter, new treatment options were available including IFNbased and other IFN-free regimens. Objectives: The aim was to assess the efficacy (SVR24) of DT and a selection of predictive factors of SVR in HCV-4 infected patients. METHODS: 112 patients (62 men) of median age 23 years were treated with DT for 48/72 weeks (107/5)...

The host immune response is critical for homeostasis; however, when chronic low level activation of the immune response with or without the driver continues, a cascade of events can trigger immunological dysfunction. Monocytes are key peripheral sensors of the immune response and their activation is instrumental in the development of cognitive impairment. Here, we show that monocytes activated by interferon alpha, lipopolysaccharide or a combination of both generate exosomes carrying significantly altered microRNA profiles compared to non-activated monocytes...

BACKGROUND: Current treatments for chronic hepatitis B (CHB) include pegylated interferon alpha (PEG-IFN-α) which is an immune modulator, and nucleos(t)ide analogs (NAs) which directly inhibit HBV DNA polymerase. With the limited efficacy of PEG-IFN-α and prolonged treatment periods associated with NAs, there is an urgent need for novel therapeutic strategies, especially for patients with a poor early response to anti-viral therapy. METHODS: In this study, 178 patients with chronic hepatitis B (n = 131) and compensated (n = 47) HBV-induced cirrhosis were enrolled, 120 patients with HBeAg (+)...

Mycosis fungoides (MF), the most common variant of among cutaneous T cell lymphomas (CTCL), is characterised in its early stages by clonal proliferation of malignant T-cells in the skin manifesting as erythematous patches and plaques with a chronic course and progression to cutaneous tumors and extracutaneous organs in some patients. Skin directed therapies (SDT) are primarily used for effective palliation in early stage disease. Phototherapy with ultraviolet A radiation combined with 8-methoxypsoralen (PUVA) and with ultraviolet B radiation (UVB) has a longstanding history in the treatment of MF and are highly effective in inducing remissions...

Patients receiving the cytokine immunotherapy, interferon-alpha (IFN-α) frequently present with neuropsychiatric consequences and cognitive impairments. Patients (25-80%) report symptoms of depression, including, anhedonia, irritability, fatigue and impaired motivation. Our lab has previously demonstrated treatment (170,000IU/kg sc, 3 times per week for 4weeks) of the pro-inflammatory cytokine, IFN-α, induced a depressive phenotype in rats in the forced swim test (FST). Here, we examine the biological mechanisms underlying behavioral changes induced by IFN-α, which may be reflective of mechanisms underlying inflammation associated depression...

Despite the good clinical efficacy of interferon-alpha (IFNα) to treat some types of cancer and viral infections, this biological drug is underused given its severe adverse effects and high dosing parenteral regimens. Aiming to achieve a breakthrough in therapy with IFNα, this work reports for the first time on the design and full characterization of a novel nanomedicine of IFNα-2b-loaded chitosan nanoparticles (IFN-CT NPs) for oral delivery. IFN-CT NPs produced by ionotropic gelation, encapsulating approximately 100% of the drug, showed a size of 36 ± 8 nm, zeta potential of +30 mV (dynamic light scattering), and spherical morphology (transmission electron microscopy)...

Antiviral treatment options for chronic Hepatitis E Virus (HEV) infections are limited and immunological determinants of viral persistence remain largely unexplored. We studied the antiviral potency of pegylated interferon-α (pegIFNα) against HEV infections in humanized mice and modelled intrahepatic interferon stimulated gene (ISG) responses. Human gene expression levels in humanized mouse livers were analyzed by qPCR and Nanostring. Human CXCL10 was measured in mouse serum. HEV genotype 3 (gt3) infections were cleared from liver and feces within 8 pegIFNα doses in all mice and relapsed after a single pegIFNα injection in only half of treated animals...

David Durantel
Current therapies of chronic hepatitis B (CHB) remain limited to pegylated-interferon-alpha (pegIFN-α) or any of the five approved nucleos(t)ide analogues (NA). If viral suppression can be achieved in the majority of patients with the high-barrier-to-resistance new-generation of NA, i.e. entecavir and tenofovir, HBsAg loss is achieved by PEG-IFN-α and/or NA in only 10% of patients, after a 5-year follow-up. Attempts to improve the response by administering two different NA or a combination of NA and PEG-IFN-α have not provided a dramatic increase in the rate of "functional cure"...

Adequate therapeutic management of cutaneous T-cell lymphoma (CTCL) requires the identification of the exact CTCL stage and entity within the current WHO classification. There is no curative therapy for CTCL yet, so that treatment currently aims at improving symptoms and quality of life as well as reducing relapse rates. The treatment has to be stage-adapted. Therapeutic options comprise skin-directed as well as systemic treatment. In early stages, phototherapy and local steroids are the first-line therapeutic options...
