PURPOSE: Corticosteroids are efficient anti-inflammation treatments. However, there are still arguments on whether it should be used in keratitis. This study was to observe the effect of corticosteroids on keratocytes both in normal condition and inflammation status in vitro. METHODS: Rat keratocytes were cultured and used for examination. 10 μg/ml lipopolysaccharide (LPS) was used to establish the inflammatory keratocyte cell model, and prednisolone acetate (PA), dexamethasone (Dex) and fluorometholone (Flu) were used as corticosteroids treatments...

Candida glabrata is one of most prevalent yeast in fungal infections, especially in immunocompromised patients. Its azole resistance results in a low therapeutic response, particularly when associated with biofilms. The main goal of this work was to study the effectiveness of voriconazole (Vcz) against C. glabrata biofilms oral pathologies, as esophageal or oropharyngeal candidiasis. Antifungal susceptibilities were determined in pre-formed 24-h-biofilms and ERG genes expression was determined by qRT-PCR. Protein quantification was performed using BCA(®) Kit, carbohydrate was estimated according to the Dubois assay and β-1,3 glucans concentration were determined using Glucatell(®) kit...

Background &Aims: Sofosbuvir is a powerful drug for treatment of hepatitis C virus (HCV) infection. In comparison to preceding remedies, sofosbuvir-based regimens provide a higher cure rate, fewer side effects, and much lower duration of treatment. The aim of the work was to assess the efficacy and safety of sofosbuvir plus ribavirin with or without peginterferon-alfa in treatment of a cohort of Egyptian patients with hepatitis C virus infection. METHODS: Two hundred treatment naive patients who were HCV-antibody positive and HCV RNA by PCR positive aged more than 18 years were enrolled in the study and patients were classified into two groups: Group I which included 100 patients who received dual therapy with sofosbuvir plus oral weight based ribavirin and Group II which included 100 patients triple therapy with sofosbuvir plus oral weight based ribavirin (as with the dual therapy) and a 180 mcg Peg-INF alpha 2a subcutaneous injection weekly for 12 weeks...

Myeloid-derived suppressor cells (MDSCs) accumulate in tumor-bearing hosts and play a key role in the suppression of the innate and adaptive immunity. Chemotherapeutic strategies have been developed to deplete or deactivate MDSCs in different tumor models. The pyrimidine analog, 5-fluorouracil (5-FU) is found to reduce the tumor size by depleting MDSCs. Here, we asked whether the purine analog, fludarabine (Flu), could exert similar effects. Employing a lymphoma model, we demonstrated that in mice with advanced tumors (where MDSC-induced suppression was present), treatment with a single low-dose Flu (25, 50, 100mg/kg) elevated the numbers of splenic MDSCs and serum arginase activity, and simultaneously, increased the tumor growth (only the highest dose)...

Cytomegalovirus (CMV) is a DNA herpesvirus that is common worldwide. The two known main sources of primary CMV infection during pregnancy are through sexual activity and contact with young children. Primary infection occurs in approximately 1 to 4% of pregnancies, and is mostly asymptomatic in immunocompetent adults. However, primary infection may manifest as a mild mononucleosis or flu-like syndrome with persistent fever and fatigue. CMV can be transmitted from mother-to-child in utero, intrapartum, or during breastfeeding...

Background/Aims A single best endpoint for evaluating treatments of severe influenza requiring hospitalization has not been identified. A novel six-category ordinal endpoint of patient status is being used in a randomized controlled trial (FLU-Intravenous Immunoglobulin - FLU-IVIG) of intravenous immunoglobulin. We systematically examine four factors regarding the use of this ordinal endpoint that may affect power from fitting a proportional odds model: (1) deviations from the proportional odds assumption which result in the same overall treatment effect as specified in the FLU-IVIG protocol and which result in a diminished overall treatment effect, (2) deviations from the distribution of the placebo group assumed in the FLU-IVIG design, (3) the effect of patient misclassification among the six categories, and (4) the number of categories of the ordinal endpoint...

BACKGROUND: Dendritic cells (DCs) enhance the quality of anti-tumor immune response in patients with cancer. Thus, we posit that DC-based immunotherapy, in conjunction with toll-like receptor (TLR)-3 agonist poly-ICLC, is a promising approach for harnessing immunity against metastatic or locally advanced unresectable pancreatic cancer (PC). METHODS: We generated autologous DCs from the peripheral blood of HLA-A2(+) patients with PC. DCs were pulsed with three distinct A2-restricted peptides: 1) human telomerase reverse transcriptase (hTERT, TERT572Y), 2) carcinoembryonic antigen (CEA; Cap1-6D), and 3) survivin (SRV...

Bronchiolitis obliterans with organizing pneumonia is an inflammatory reaction that can occur as a consequence of various pulmonary affections. Radiotherapy is not the sole and systematic cause of bronchiolitis obliterans with organizing pneumonia. Radiation-induced should not be confused with post-radiation, dose-dependent, inflammatory pulmonary fibrosis, which is non-immunological and located within the irradiation field. The role of immunity, local inflammation and individual radiosensitivity in bronchiolitis obliterans with organizing pneumonia is not well defined...

OBJECTIVE: Flutamide (FLU) is a non-steroidal antiandrogen drug approved for the treatment of advanced prostate cancer. While this indication limits the use to male patients, FLU is widely prescribed to women, off-label, for the treatment of polycystic ovary syndrome (POCS) related hirsutism and acne. According to the literature, its assumption is associated with a higher incidence of adverse events in women than in male patients. MATERIALS AND METHODS: A literature search was conducted in main databases targeting unwilling FLU effects in hepatic and reproductive function...

Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is a rare inflammatory chorioretinopathy, which mainly affects young light-skinned, myopic adults between 20 and 30 years of age. The exact aetiology of APMPPE is unknown. Some patients report a viral or flu-like illness preceding the onset of APMPPE symptoms. This condition is usually bilateral and self-limiting with a good overall prognosis. Visual loss is sudden, but usually temporary. Relapses are very rare. Foveal involvement may lead to a worse visual prognosis...

OBJECTIVES: Candida glabrata is becoming one of the most prevalent pathogenic yeasts in cases of oral diseases. Mucositis is an recurrent oral infection in immunocompromised patients, and the actual guidelines recommend the use of fluconazole (Flu) for many cases. However, the azole resistance by C. glabrata is renowned, causing a reduced therapeutic response, especially when it occurs in biofilms. In this study, we performed an in vitro evaluation of an alternative pharmacotherapy for C...

The ectodomain of the influenza A matrix protein 2 (M2e) is highly conserved amongst all influenza virus A subtypes. M2e is present on the surface of influenza A virus-infected cells, and therefore a suitable target for broadly protective therapies. We designed bispecific T cell engaging (BiTE(®)) antibody constructs specific for M2e by genetically fusing a single chain variable fragment (scFv) derived from an M2e-specific murine monoclonal antibody with a CD3ɛ-specific scFv. These so-called FLU BiTE(®) antibody constructs selectively mediate T cell dependent lysis of M2-expressing and influenza A virus infected cells and protect BALB/c mice against challenge with different influenza A virus subtypes...

Zika virus (ZIKV) disease is caused by a virus transmitted by Aedes mosquito. It presents as flu-like symptoms lasting for 5-7 days and shows potential association with neurological and autoimmune complications such as congenital microcephaly and adult paralysis disorder, Guillain-Barré syndrome. Treatment measures are conservative as the disease is self-limiting. ZIKV earlier affected several tropical regions of Africa and Asia from 1951 to 2006. Subsequently, it moved out from these regions to land as outbreaks in Yap Island, French Polynesia, South America, and most recently in Brazil...

BACKGROUND: Hemophagocytic lymphohistiocytosis is a disease process characterized by unregulated hyperactivation of the immune system associated with multiorgan involvement and high mortality rates. Early recognition is crucial and a recently validated diagnostic schema, the H-Score, may facilitate diagnosis particularly in secondary hemophagocytic lymphohistiocytosis cases. We present a patient with secondary hemophagocytic lymphohistiocytosis in association with metastatic renal cell carcinoma in whom high-dose steroid therapy induced a remarkable response...
