Clinical Trial of High-Dose Pegylated-Interferon-Alfa-2b Combined With Phototherapy in Advanced Stage Mycosis Fungoides.

The combination of Interferon-α-2b (IFN-α-2b) and phototherapy is highly effective in treating mycosis fungoides (MF) but side effects often lead to discontinuation of therapy.1.

Safety of combination interferon alfa-2b/ribavirin therapy in chronic hepatitis C-relapsed and treatment-naive patients.

The coadministration of ribavirin with recombinant interferon alfa-2b (rIFN-alpha 2b) compared with rIFN-alpha 2b alone markedly enhanced sustained virologic response rates in relapsed and treatment-naive chronic hepatitis C patients. The potential for ribavirin to likewise exacerbate the adverse events associated with the alpha interferons is reviewed. The overall safety and tolerability of combination rIFN-alpha 2b/ribavirin therapy was evaluated in 2,089 patients treated in phase III clinical studies conducted in the United States and internationally. Serious adverse events were also evalua

Induction of class I major histocompatibility complex antigen expression by West Nile virus on gamma interferon-refractory early murine trophoblast cells.

Primary murine trophoblast giant cells (TGC) do not express detectable major histocompatibility complex (MHC) antigens and are refractory to the MHC-increasing effects of alpha and beta (virus-induced) interferons and gamma (immune type) interferon during early implantation (postcoital days 3.5-6). West Nile virus infection of primary TGC monolayers from postcoital-day-3.5 preimplantation blastocysts induced paternal MHC antigen expression within 16 hr, as detected by immunogold labeling for electron microscopy. Induction is unlikely to have been mediated by secreted virus-induced interferons

Systemic interferon therapy of multiple sclerosis: the pros.

The rationale for the use of interferon (IFN) in the treatment of multiple sclerosis (MS) is based on its recognized antiviral and immunomodulating actions. The pathogenesis of MS is generally believed to be due to an immunologic response in a genetically predisposed individual, localized within the CNS white matter, and triggered by exposure to an environmental agent such as a virus. In a randomized, double-blind, placebo-controlled, crossover trial of systemic natural alpha IFN in 24 patients with exacerbating-remitting MS, patients with a strictly exacerbating-remitting course showed a redu

Interferon-induced vitiligo in a patient with chronic viral hepatitis C infection.

Vitiligo is an autoimmune disease characterized by depigmentation of the skin due to destruction of melanocytes. Interferons have been used for the treatment of chronic hepatitis C and some malignancies. We report interferon alpha-2a-induced vitiligo in a male patient with chronic active hepatitis C. All skin lesions disappeared completely without requiring therapy after discontinuation of interferon. This case suggests that vitiligo may be developed during interferon therapy as a side effect.

A case of erythrodermia from exacerbated psoriasis vulgaris due to treatment of acute hepatitis C.

BACKGROUND: Skin side effects during interferon-alpha and ribavirin treatment are common, but autoimmune dermatosis triggered by interferon-alpha is rare. We describe a case of erythrodermia from exacerbated psoriasis during the treatment of acute hepatitis C with pegylated-interferon-alpha and ribavirin. The incidence of psoriasis in this circumstance is unknown and only 36 cases are described in the literature, of which only one describes an erythrodermic psoriasis flare. CASE PRESENTATION: A 50-years old healthy white man presented with the complaints of headache, muscle pain, appetite los…

Thrombotic microangiopathy associated with use of interferon-beta.

Interferon-beta is widely used for the treatment of relapsing multiple sclerosis. The drug is usually well tolerated, but autoimmune adverse effects, including kidney disease, have been reported. Only a few cases of hemolytic uremic syndrome-thrombotic microangiopathy associated interferon-alpha have been described so far, and even fewer with beta-interferon. We report a patient who developed thrombotic microangiopathy during treatment with interferon-beta and improved after discontinuation and steroid therapy. Complement cascade and antiphospholipid antibodies are investigated. The spectrum o…

[Treatment of chronic hepatitis C with lymphoblastic interferon. Long-term follow-up].

OBJECTIVES: A randomized controlled trial was set up to assess the effect of two different therapy regimens with lymphoblastoid interferon on the treatment and follow-up of patients with chronic C hepatitis. METHODS: Eighty-five patients with chronic hepatitis C were randomized into two treatment groups (n = 30 respectively) and one control group (no treatment: n = 25). In one treatment group patients received three million units of alpha-lymphoblastoid interferon. The other received six million units. RESULTS: A rapid decline in both alanine aminotransferase and aspartataminotransferase lev

Bulevirtide and emerging drugs for the treatment of hepatitis D.

INTRODUCTION: Hepatitis delta virus (HDV) causes acute and chronic liver disease that requires the co-infection of the Hepatitis B virus and can lead to significant morbidity and mortality. Bulevirtide is a recently introduced entry inhibitor drug that acts on the sodium taurocholate cotransporting peptide, thereby preventing viral entry to target cells in chronic HDV infection. The mainstay of chronic HDV therapy prior to bulevirtide was interferon alpha, which has an undesirable side effect profile. AREAS COVERED: We review bulevirtide data from recent clinical trials in Europe and the Unit

Role of the promyelocytic leukemia protein PML in the interferon sensitivity of lymphocytic choriomeningitis virus.

Lymphocytic choriomeningitis virus (LCMV) induces type I interferon (alpha and beta interferon [IFN-alpha and IFN-beta]) upon infection and yet is sensitive to the addition of type II interferon (gamma interferon [IFN-gamma]) to the culture media. This sensitivity is biologically important because it correlates inversely with the ability of certain LCMV strains to persist in mice (D. Moskophidis, M. Battegay, M. A. Bruendler, E. Laine, I. Gresser, and R. M. Zinkernagel, J. Virol. 68:1951-1955, 1994). The cellular oncoprotein PML is induced by both IFN-alpha/beta and IFN-gamma, and PML binds th

Интерлейкин-1бета, интерлейкин-1 рецепторные антагонистические уровни у пациентов с субакутным склерозом панэнцефалита и эффектом различных протоколов лечения.

Подводные склерозы панэнцефалита — это редкое прогрессивное воспалительное заболевание центральной нервной системы, вызванное стойкой аберрантной корью. Цитокины - это полипептиды, которые регулируют иммунную реакцию и подстрекательские реакции. Interleukin-1beta была замешана в качестве центрального посредника в повреждении тканей и разрушении ряда заболеваний центральной нервной системы. Интерлейкин-1-рецепторный антагонист может функционировать как важный антивоспалительный цитокин. Мы изучали уровни интерлейкина-1беты и интерлейкина-1 рецептора антагонистов в цереброспинных жидкостях пацие

[Molecular diagnosis and therapeutic strategy for Philadelphia chromosome-positive acute leukemia].

We focused on biological characteristics of Philadelphia chromosome-positive acute leukemia (Ph+ AL) and treated those patients with BHAC-DMPV induction chemotherapy. After obtaining complete remission, we attempted to treat with allogeneic bone marrow transplantation, while those without suitability for marrow transplantation were treated with alpha-interferon (IFN-alpha), in order to obtain prolong remission status. Chromosomal and molecular analyses, including BCR rearrangement and BCR -ABL mRNA, before and after IFN-alpha treatment demonstrated a recovery of normal hematopoiesis by the tre

Pancreatic beta-cell-selective production of tumor necrosis factor-alpha induced by interleukin-1.

Cytokines have been regarded as effector molecules responsible for beta-cell death and major histocompatibility complex hyperexpression in endocrine pancreas of type I diabetes. However, the mechanism that results in beta-cell-selective destruction has not been elucidated. We demonstrated in this study, using cell lines of transformed mouse beta-cells and alpha-cells, that only pancreatic beta-cells but not alpha-cells produced tumor necrosis factor-alpha when exposed to interleukin-1 beta. Northern blot analysis confirmed the beta-cell-selective expression of tumor necrosis factor-alpha mRNA.

Combating pan-coronavirus infection by indomethacin through simultaneously inhibiting viral replication and inflammatory response.

Severe infections with coronaviruses are often accompanied with hyperinflammation, requiring therapeutic strategies to simultaneously tackle … tiator of interferon response through increasing STAT1 phosphorylation. Combining indomethacin with interferon-alpha exerted synergistic antiviral effects against multiple coronaviruses. The anti-coronavirus activity of indomethacin is associated with activating interferon response. In a co-culture system of lung epithelial cells with macrophages, indomethacin inh …

Atypical chronic graft-versus-host disease following interferon therapy for chronic myeloid leukaemia relapsing after allogeneic BMT.

We report a 54-year-old woman who received interferon alpha for haematological relapse of Ph-positive CML, 7 years after allogeneic BMT from an HLA-identical brother. Eighteen months after relapse, cytogenetic and molecular remission was achieved. She received interferon therapy for 25 months and it was discontinued when she developed skin lesions on her face and trunk, dysphagia and fever with respiratory failure and bilateral patchy airspace consolidation of the lung without microbiologic findings. Histologic features showed discoid lupus erythematosis, oesophagitis with pseudomembranes and

Natural interferon-beta treatment for patients with chronic hepatitis C in Japan.

Chronic hepatitis C virus (HCV) infection can cause liver cirrhosis and hepatocellular carcinoma (HCC). Several studies have demonstrated that the eradication of HCV reduces the occurrence of HCC. In Japan, as many people live to an advanced age, HCV-infected patients are also getting older, and the age at HCC diagnosis has also increased. Although older HCV-infected patients have a risk of developing HCC, the treatment response to peginterferon-alpha plus ribavirin therapy is relatively poor in these patients because of drop-out or discontinuation of this treatment due to adverse events. It i…

The effect of intraventricular interferon on subacute sclerosing panencephalitis.

Two patients with subacute sclerosing panencephalitis (SSPE) were treated with intraventricular alpha interferon (IFN-alpha) via an Ommaya reservoir for 20-57 months. The clinical course of the disease was followed for 20-67 months. Clinical improvement was observed after daily intraventricular administration of IFN in one case. There were no serious complications or side effects during interferon therapy except for the fever. Intraventricular administration of IFN appears superior to intrathecal administration for long-term treatment in several respects and is considered to be a potential the

Effects of cytokines from virus-induced human lymphoblasts on the growth and viability of the promyelocytic leukemia cell line HL-60.

Cells of the human B-cell lymphoblastic leukemia line, BALL-1, were stimulated with Sendai virus. It is shown that the crude culture supernatants contain not only interferon-alpha (IFN-alpha) and tumor necrosis factor-alpha (TNF-alpha) but also other cytokines, here collectively termed 'X' cytokines. The latter did not affect the cytostatic or differentiation-inducing effect of IFN-alpha but synergistically increased the cytotoxicity of TNF-alpha.

Expression of plasmacytoid dendritic cells, IRF-7, IFN-alpha mRNA in the lesions of psoriasis vulgaris.

To investigate the expression of plasmacytoid dendritic cells (pDCs), interferon regulatory factor-7 (IRF-7) and interferon alpha (IFN- alpha) mRNA in skin lesions of patients with psoriasis vulgaris, the expressions of plasmacytoid dendritic cells, IRF-7, IFN-alpha mRNA in the lesional skin of psoriasis vulgaris were detected by immunohistochemical technique (SP) and RT-PCR. Normal skin of healthy volunteers, serving as control, was also tested. The immunohistochemical study showed that the expression of pDCs in the psoriatic lesions was significantly higher than that in the normal controls.

The proinflammatory CXC-chemokines GRO-alpha/CXCL1 and MIG/CXCL9 are concomitantly expressed in ulcerative colitis and decrease during treatment with topical corticosteroids.

BACKGROUND: Ulcerative colitis is characterized by relapsing mucosal inflammation where the lesions include tissue-damaging granulocytes. In addition, T cells and natural killer (NK) cells play important pathophysiologic roles. Chemokines are a large family of peptides that play key roles in the regulation of inflammation. The CXC-chemokines, growth-related oncogene (GRO)-alpha/CXCL1 and interleukin (IL)-8/CXCL8, both recruit neutrophils and possess mitogenic properties, whereas the interferon-dependent CXC-chemokines monokine induced by gamma-interferon (MIG)/CXCL9, interferon-gamma inducible
