Recurrent airway obstruction (RAO) represents a serious health problem and is traditionally classified as an allergic disease, where contact with an antigen can induce clinical airway inflammation, bronchial hyper-responsiveness and reversible airway obstruction. Previous studies have demonstrated the presence of the Th2 response in the lungs of human patients with asthma and horses with heaves. These cells are involved in the production of cytokines which regulate the synthesis of immunoglobulins. 40 horses were evaluated: 30 horses with RAO and 10 healthy animals...

BACKGROUND: Kasabach-Merritt syndrome (KMS) is a rare but life-threatening illness. The purpose of this study is to report our single-center experience with KMS. METHODS: We reviewed the medical records of 13 patients who were diagnosed with KMS between 1997 and 2012 at Samsung Medical Center. Treatment response was defined as follows: 1) hematologic complete response (HCR) - platelet count >130×10(9)/L without transfusion; 2) clinical complete response (CCR) - complete tumor disappearance or small residual vascular tumor displaying lack of proliferation for at least 6 months after treatment discontinuation...

Recent studies regarding mucosal drug delivery indicate that nanosystems with surface-available polyethylene glycol (PEG) are able to penetrate mucus barrier, assure closer contact with the epithelium, and improve drug delivery to vagina. In the present work, we developed the mucus-penetrating PEGylated liposomes containing interferon alpha-2b (IFN α-2b), destined to provide localized therapy for human papilloma virus (HPV) vaginal infections. The PEGylated liposomes were of a mean size of 181 ± 8 nm, bearing a negative zeta potential of - 13 mV and an entrapment efficiency of 81 ± 10 %...

Thyroid dysfunction is a common and severe side-effect encountered in up to 40% of patients treated with IFN-alpha-2a. The main two mechanisms by which IFN-alpha-2a induces thyroid dysfunction can be categorized as autoimmune and non-autoimmune disease. In the first subgroup, thyroid antibodies are found before treatment initiation, and then patients develop thyroiditis. In the second subgroup, IFN-alpha-2a induces thyroiditis by a direct cytotoxic effect on the thyroid gland; in this case, thyroid antibodies are usually negative...

Hendra virus and Nipah virus (NiV) are highly pathogenic zoonotic paramyxoviruses, from henipavirus genus, that have emerged in late 1990s in Australia and South-East Asia, respectively. Since their initial identification, numerous outbreaks have been reported, affecting both domestic animals and humans, and multiple rounds of person-to-person NiV transmission were observed. Widely distributed fruit bats from Pteropodidae family were found to be henipavirus natural reservoir. Numerous studies have reported henipavirus seropositivity in pteropid bats, including bats in Africa, thus expanding notably the geographic distribution of these viruses...

Chronic Hepatitis B is a major global health issue, and has no known cure. Currently there are over 240 million people infected with the disease, and it leads to the death of over 686,000 people each year. A total of seven treatments which help to control the disease are currently available: interferon-based treatments (pegasys, and interferon alpha), and nucleoside and nucleotide analogs (Viread, Baraclude, Tyzeka, Hepsera, Epivir-HBV), but all require continuing treatment to maintain control of the disease...

Treatment with either pegylated interferon-alpha (pegIFN-α) or last generation nucleos(t)ide analogues (NAs) successfully leads to serum viral load suppression in most chronically infected hepatitis B (CHB) patients, but HBsAg loss is only achieved in 10% of the cases after a 5-year follow-up. Thus, therapy must be administered long-term and it will not completely eliminate infection because of the persistent hepatitis B virus (HBV) minichromosome in infected cells, and cannot completely abolish the risk of developing severe sequelae such as cirrhosis and hepatocellular carcinoma...

PURPOSE: Various targeted disease-specific therapeutics are currently approved, demonstrating a survival benefit over therapy with interferon-alpha (IFN-α) in patients with metastatic renal cell carcinoma (mRCC). Temsirolimus, a highly specific inhibitor of the mammalian target of rapamycin (mTOR), improves the overall and progression-free survival of high-risk patients with mRCC. The purpose of this study was to estimate the effects of temsirolimus on several laboratory parameters and to report the potential adverse events (AEs) in patients with mRCC...

Long-term treatment with high-dose Interferon-alpha (IFN-α) has resulted in depression in 30-50% of the patients. Paeoniflorin may ameliorate the IFN-α-induced depression; however, the underlying mechanism is less studied. Here, we investigated the prophylactic antidepressant and anti-neuroinflammatory effects of paeoniflorin on the behaviors and specific emotion-related regions of the brain in mice with IFN-α-induced depression. A series of behavior assessments were conducted to identify the depressive state after subcutaneously IFN-α injections and with or without intragastrically paeoniflorin administration in C57BL/6J mice...

Interferon alpha (IFNα) is a cytokine approved for the treatment of several types of cancer. However, the modest effect on overall survival and the high toxicity associated with the treatment has reduced the clinical use of this cytokine. In this study, we have developed a tumor model that reproduces this clinical setting. A high dose of an adeno-associated virus encoding IFNα (AAV-IFNα) was able to eradicate a liver metastases model of colon cancer but induced lethal pancytopenia. On the other hand, a safe dose of AAV-IFNα was not able to eliminate the liver metastases of colon cancer...

OBJECTIVES: Type 1 diabetes results from T-cell-mediated destruction of the beta cells of the pancreas and is associated with several autoimmune phenomena. Many studies have suggested the involvement of interferon alpha (IFN α) in the development of type 1 diabetes, but the exact mechanism remains unclear. In this study, the binding of type 1 diabetes antibodies with recombinant interferon alpha-2b (hrIFN α-2b), their gene (cIFN α-2b gene) and commercially available interferon α-2b (IFN α-2b) were assessed...

Recurrent laryngeal papillomatosis (RRP) can be a devastating condition for a child to endure, and pulmonary involvement may have terminal consequences. Adjuvant therapies have been trialed and reported over the years; however, these chemotherapy options have not been successful. Bevacizumab (Avastin, Genetech Inc., South San Francisco, CA) is a vascular endothelial factor (VEGF) inhibitor that has shown promise in the management of papillomatosis. Most research has focused on intralesional injections of this antiangiogenic drug...

Ocular surface squamous neoplasia (OSSN) is a common ocular surface tumor with an increased incidence in African countries (3.4 and 3.0 cases/year/100,000). Despite its potential for vision loss and death, OSSN remains largely neglected by both eye and HIV care programs in Africa. The purpose of this review is to identify the barriers to timely diagnosis and early interventions for OSSN in Africa. PubMed searches were conducted targeting previous use of topical chemotherapy (interferon alpha 2b, Mitomycin-C, 5-Fluorouracil) and Human papillomavirus (HPV) vaccination in Africa...

: Enhancement of host anti-oxidant enzymes, such as heme oxygenase-1, may attenuate virus-mediated hepatocyte injury, while the induction of HO-1 by cobalt-protoporphyrin-IX (CoPP) administration, as the application of its heme degradation product biliverdin (BV), was shown to hinder HCV replication in vitro. Additionally, (GT)n -repeats length in the polymorphic region of the HO-1 promoter may affect HO-1 expression and responsiveness to infection and disease severity. Aim of this study was to investigate the antiviral and hepatoprotective effects of CoPP-mediated HO-1 induction, alone or in combination with interferon alpha (peg-IFNα), in HCV-infected mice harboring hepatocytes from donors with different HO-1-promoter polymorphisms...

Nanoparticles of defined size can be easily obtained by simply mixing Protamine, a pharmaceutical drug that is used to neutralize heparin after surgery, and RNA in the form of oligonucleotides or messenger RNA. Depending on the concentrations of the two reagents and their salt contents, homogenous nanoparticles with a mean diameter of 50 to more than 1000 nm can spontaneously be generated. RNA is a danger signal because it is an agonist of for example TLR-3, -7, and -8; therefore, Protamine-RNA nanoparticles are immunostimulating...

An estimated 350 million people are chronically infected with hepatitis B virus (HBV), and over one million people die each year due to HBV-associated liver diseases, such as cirrhosis and liver cancer. Current therapeutics for chronic HBV infection are limited to nucleos(t)ide analogs and interferon. These anti-HBV drugs in general reduce viral load and improve the long-term outcome of infection but very rarely lead to a cure. Thus, new therapies for chronic HBV infection need to be developed by utilizing liver cell lines and primary cultures and small laboratory animals capable of replicating HBV or surrogate hepadnaviruses for antiviral testing...
