It has been reported that the administration of interferon alpha-2b is of potential benefit in the treatment of mastocytosis based on a single patient study (NEJM, Feb 27, 1992, 326(9):619-623). Following this report, we administered interferon alpha-2b at a dose of 4 to 5 million units per square meter of body surface area for at least 12 months to one patient with mastocytosis with an associated hematologic disorder (patient 1), one patient with aggressive systemic mastocytosis (patient 2), and one patient with indolent mastocytosis (patient 3). Patients were monitored with the following clinical and laboratory parameters: serial bone marrow biopsies and aspirates, patient log of histamine release attacks, medication dependency, plasma tryptase levels, serum lactate dehydrogenase (LDH) levels, white blood cell counts and differentials, extent of urticaria pigmentosa lesions, bony involvement, and extent of gastrointestinal involvement and hepatomegaly. We also examined the ability of interferon alpha-2b to inhibit recombinant human stem cell factor (rhSCF)-dependent mast cell proliferation from CD34+ bone marrow-derived cells. All patients demonstrated continued progression of disease in one or more clinical criteria at one year of therapy. Similarly, interferon alpha-2b did not inhibit the culture of mast cells from CD34+ bone marrow-derived cells in the presence of SCF. Thus, in our study of three patients with systemic mastocytosis, treatment with interferon alpha-2b was found to be ineffective in controlling progression of disease.

A 69-year-old man was found to have leukocytosis and a bleeding tendency, when he underwent surgery for hemorrhoids in November 1992, at the age of 69. The patient was referred to our department for further examination, and was admitted on December 4. On admission, he had hepatomegaly (5 cm) and splenomegaly (12 cm). Laboratory data on admission showed that the leukocyte count was 173,400/microliter, erythrocyte count, 314 x 10(4)/microliter, hemoglobin level, 10.5 g/dl, hematocrit value, 29.7%, and platelet count, 14.4 x 10(4)/microliter, respectively. Peripheral hemogram revealed neutrophilia with a shift to the left to promyelocytes, and the positivity of neutrophil alkaline phosphatase (NAP) was very low. The bone marrow was hyperplastic with a high M/E ratio (5.8). As the chromosome analysis revealed that he had 9:22 translocation in all 20 karyotypes, chronic myelogenous leukemia in the chronic phase, was diagnosed. After the daily intramuscular administration of 9 megaunits interferon alpha-2b was started on December 9, 1992, his leukocyte count stabilized between 5,000 and 8,000/microliter. Thereafter, intramuscular administration of IFN alpha has been continued regularly almost twice a week at the outpatient clinic until now. The leukocyte count ranges from 3,000 to 6,000/ml and he is asymptomatic. In April 1995, complete cytogenetic response was achieved 28 months after the start of interferon alpha therapy. The recent bone marrow chromosomes examination showed Philadelphia-negative metaphases until now, December, 2002, although major bcr-abl still remains positive. This case suggests that treatment with interferon alpha may still be useful in some elderly patients with chronic myelogenous leukemia.

The case report of a young female patient with personal history of primary thrombocythaemia, treated with interferon alpha, admitted to our medical department for severe abdominal pain, hepatomegaly, ascites and alteration of hepatic function is presented. Magnetic resonance imaging showed the picture typical for Budd-Chiari syndrome caused by external obstruction of the intrahepatal portion of inferior vena cava. The cause of the syndrome remains uncertain, possibility of the haematogenic infiltration of the liver or venal thrombosis within primary or secondary (interferon-induced) antiphospholipid syndrome is discussed. Liver biopsy could elucidate the exact cause, but it was not performed for technical problems.
