We report on two patients with Ph+ chronic myeloid leukemia (CML) in chronic phase who developed severe thrombocytopenia during treatment with interferon-alpha 2A (IFN-alpha 2A). In both cases, we detected the presence of platelet-associated antibodies (PAIg) by autoimmune flow cytometry. We postulated an immune mediated platelet destruction mechanism; corticosteroid therapy was employed and in...
In 2004, we reported the short-term results of a multicentric, phase 2 study of imatinib 400 mg daily and pegylated interferon-alpha in the treatment of 76 early chronic phase Philadelphia-positive chronic myeloid leukemia patients. In this report, we update the results with an observation time of five years. After two years of treatment, all but 10 patients (13%) had discontinued pegylated int...
A 67-year-old man was admitted with a chief complaint of dyspnea. Computed tomography (CT) revealed a left renal tumor, 12 cm in diameter, with tumor thrombus in the left renal vein, multiple lung metastases, right pleural effusion, and para-aortic lymph node metastases. Because of poor condition in respiratory status, nephrectomy was considered to be impossible and the patient was administered...
The allele Mx regulates the extent to which interferon alpha/beta inhibits the growth of influenza viruses in mouse cells such as peritoneal macrophages. The time course of induction of the antiviral state against an influenza A virus is comparable in macrophages with and without Mx and is similar to that found with vesicular stomatitis virus. In contrast, the decay of the antiviral state again...
BACKGROUND Studies using neuroimaging and in vivo microdialysis in humans and nonhuman primates indicate that inflammatory cytokines such as interferon-alpha reduce dopamine release in the ventral striatum in association with depressive symptoms including anhedonia and psychomotor slowing. METHODS Herein, we examined whether reduced striatal dopamine release in rhesus monkeys chronically trea...
A 68-year-old man with multiple pulmonary metastases from a right renal cell carcinoma was treated with alpha interferon, but there was no improvement. For this reason, alpha interferon was ceased, and daily monotherapy with recombinant interleukin-2 (1,000,000 units/day) was commenced. After 4 months, plain chest x-ray and chest CT revealed complete clearance of the pulmonary metastases. There...
Pegylated interferon alpha (PEG-IFN-alpha) is a formulation of recombinant human interferon conjugated with polyethylene-glycol. This preparation has a long half-life (compared with conventional IFN), which allows for once-weekly injection. Elimination half-life of PEG-IFN-alpha 2b is 22-60 hours (average, 35-40 hours). We report the development of a local necrotizing reaction complicating subc...
We describe a 33-year old man suffering from severe vertebral osteoporosis and urticaria pigmentosa due to systemic mast cell disease (SMCD). Because i.v. clodronate therapy could not prevent further vertebral fractures, an additional treatment with interferon alpha-2b was initiated. During 24 months of treatment, our patient had no further pain episodes, no new vertebral fractures were discove...
The vesicular stomatitis virus cytopathic effect reduction assay is suitable to quantify polyethylene glycol-alpha interferon 2a (PEG-IFN-alpha 2a) and PEG-IFN-alpha 2b. Human serum and ribavirin did not interfere with the assay. This bioassay was successfully used for assaying PEG-IFN-alpha 2a and PEG-IFN-alpha 2b in serum samples from patients undergoing combination therapy.
