A case of epithelial thymoma occurring synchronously with Philadelphia chromosome-positive chronic myelogenous leukemia and urinary bladder carcinoma in a 76-year-old man is described. Thymomas have been associated with numberous hematologic, collagen-vascular and autoimmune disease states, as well as with an increased incidence of nonthymic malignancy. Human thymoma-associated leukemia is, however, extremely unusual, despite the well-documented role of the thymus in leukemogenesis in experimental animals. No previous literature reports of thymoma associated with chronic myelogeneous leukemia were found. A review of long-term followup data of surviving thymoma patients is necessary to determine if an increased propensity to develop leukemia is present in present in patients with thymoma.

Symptoms of autoimmune disease were evaluated in 125 patients with chronic myelogenous leukemia (CML) and in 12 patients with essential thrombocythemia undergoing treatment with recombinant interferon (IFN)-alpha-2b plus/minus low-dose recombinant IFN-gamma. Twenty-seven of 137 patients (20%) developed rheumatoid symptoms. Furthermore, the incidence of antinuclear antibody (ANA) formation was studied. Elevated ANA titers were found in 5/19 (26%) of CML patients at the time of diagnosis and in 3/18 (17%) of patients treated with hydroxyurea or busulfan. During IFN treatment, 18 of 25 tested patients (72%) had elevated ANA titers. In 15 of these ANA-positive patients, clinical signs of autoimmune disease appeared. All these patients were under long-term IFN treatment and were in remission of disease. In three patients criteria for systemic lupus erythematosus were fulfilled. Severity of side effects had led to the discontinuation of IFN treatment in these patients. The data indicate that IFN-alpha and IFN-gamma can induce ANA associated with autoimmune disease in patients with myeloproliferative disorders.

Lupus anticoagulant antibodies have never been reported to disappear after either allogeneic or autologous bone marrow transplantation in humans. We report the first case of disappearance of lupus anticoagulant antibodies in a patient without systemic lupus erythematosus or clinical evidence of other autoimmune disorders, who received an allogeneic bone marrow transplant as treatment for chronic myeloid leukemia. Although marrow transplantation is not a recognized therapy for antiphospholipid syndrome, our observation should be considered another example of the capability of intensive chemo-radiotherapy followed by stem cell transplantation to ablate a pathologic marrow clone resulting in an autoimmune disorder and improve, or even cure, some severe autoimmune diseases.

Treatment of autoimmune disease with bone marrow transplantation (BMT) is under investigation. A few reports of patients undergoing allogeneic BMT for malignant conditions observed the resolution of psoriasis after BMT, with minimal late morbidity. We describe a patient with chronic myelogenous leukemia (CML) whose psoriasis resolved completely after allogeneic BMT. However, the patient's course was complicated by extensive chronic graft-versus-host disease (GVHD), recurrent serious infections, poor performance status and quality of life, and severe disability. The patient died 887 days post transplant due to infectious complications. The potential benefits and risks of treatment of autoimmune diseases with allogeneic BMT are discussed.

Serological identification of tumor antigens by cDNA expression cloning is a technique used to isolate cDNAs encoding tumor antigens that are recognized by IgG antibodies in sera from cancer patients. It is also useful for the isolation of tumor antigens recognized by T cells. We applied this method to identify melanoma antigens recognized by the serum from a patient with a good prognosis who had T-cell-infiltrated melanoma and vitiligo. By screening a lambda phage cDNA library constructed from a highly pigmented melanoma cell line, SKmel23, with the patient's serum, 50 positive cDNA clones consisting of 26 distinct antigens were isolated. Of these, 20 encoded known proteins, and 6 encoded previously uncharacterized ones. The most frequently isolated clone, which we named KU-MEL-1, was unknown previously but was homologous to partial cDNA sequences registered in the expressed sequence tag database. Reverse transcription-PCR and Northern blot analysis demonstrated that KU-MEL-1 was strongly expressed in most melanoma cell lines, melanoma tissue samples, and cultured melanocytes and weakly expressed in cell lines derived from other types of tumors, as well as in some normal tissues, including testis. Western blot analysis with polyclonal murine antibody generated by immunization with the recombinant KU-MEL-1 protein demonstrated that the KU-MEL-1 protein was preferentially expressed in melanoma cells and melanocytes. IgG antibodies against KU-MEL-1 were detected in the sera from 9 of 26 melanoma patients and from some patients with other cancers, including brain tumor, esophageal cancer, colon cancer, and chronic myelogenous leukemia, but were not detected in sera from 30 healthy individuals. Although the IgG specific for KU-MEL-1 was not detected in sera from 12 vitiligo patients, it was detected in sera from 7 of 11 patients with Vogt-Koyanagi-Harada disease that is thought to be an autoimmune disease against melanocytes. These results suggest that KU-MEL-1 may be a useful target for the development of diagnostic and therapeutic methods for patients with various cancers, particularly with melanoma, as well as patients with autoimmune diseases against melanocytes.

Interferon-alpha is the frontline therapy of the majority of chronic myeloid leukemia (CML) patients who are not eligible for bone marrow transplantation. Many patients are treated for long periods, and there is concern about the long-term immune effects of its use. Autoimmune disorders in patients treated with IFN-alpha may be related to the direct immunomodulating properties of IFN or may be linked to a possible toxic effect in target organs, triggering autoimmunity. On the other hand, the immune effects of IFN may play a role in its therapeutic actions. The aims of our study were to assess the incidence of autoimmune phenomena in these patients, and to measure the possible association between the generation of autoimmune phenomena and the antileukemic effect of IFN alpha. Therefore, 46 patients with Ph1(+) CML in the first chronic phase were studied for the appearance of immune complications, their connection to IFN dose, time of appearance, and the possible association with the response to treatment. Autoimmune abnormalities have been found in 28% of our patients. Moreover, a significant association was found between autoimmune alterations and female sex (P = 0.02, OR 4.5, 95% CI 1.13-17.9) and a longer treatment time (1.6 vs. 4.1 years) (P = 0.02; OR 1.01, 95% CI 1-1.02). The Kaplan-Meier estimated probability of obtaining a cytogenetic response was significantly higher in patients who developed autoimmune alterations (P = 0.049), and this difference was also evident in Cox's analysis when controlling with other potentially confounding variables (P = 0.078). We conclude that CML patients treated with IFN alpha have a high incidence of autoimmune phenomenon.

The development of various kinds of autoimmune disease as a result of interferon-alpha (IFN-alpha) therapy has been reported among chronic myeloproliferative disorders(CMPD) including chronic myeloid leukemia(CML). Therefore, we investigated the frequency of autoimmune disorders in 33 patients with hematopoietic diseases treated with IFN-alpha in our department. Thirty-three patients (12 females, 21 males) included cases of CML (n = 23), essential thrombocythemia (ET) (n = 1), multiple myeloma (n = 8), and hypereosinophilic syndrome (HES) (n = 1). Autoantibodies (ANA, dsDNA, and RAPA), thyroid grand functions, and coagulant functions were examined. Twenty-five out of 33 patients were treated with natural IFN-alpha, and 8 patients were treated with recombinant IFN-alpha 2b (rIFN alpha-2b). Three patients were treated with IFN and anticancer agents. Antinuclear antibodies were detected in 2 of 33 patients. RAPA and anti-thyroglobulin antibody became positive in 3 and 4 patients, respectively. Ten patients showed low serum levels of either free T3 and/or free T4. However, none of them showed any clinical symptoms for developing autoimmune diseases. In addition, circulating anticoagulant antibodies were detected in 3 of 23 patients with CML treated with rIFN alpha-2b, but in no cases treated with natural IFN-alpha. Although none of the patients developed autoimmune diseases, we concluded that patients receiving IFN therapy should be carefully monitored for clinical signs and symptoms of autoimmune disorders.

This case report is on a 40-year-old male patient with chronic myeloid leukemia (CML) receiving an allogeneic hematopoietic stem cell transplantation (HSCT) in first chronic phase from an HLA-identical sibling brother. He suffered from alopecia universalis occurring 11 years previously. The alopecia involved all body hair, including eyebrows and eyelashes. Between day 40 and day 55 after transplantation, hair started to grow on the chin, eyelashes, and on the top of his head. Immunosuppression was stopped at 6 months because of cytogenetic relapse and incomplete donor chimerism with some renewed hair loss. He returned to full donor chimerism with mild chronic graft-versus-host disease and continued hair growth. With 2 years of follow-up he has remained in continuous remission. Chimerism analyses of hair follicles did not show any donor alleles. Alopecia universalis is probably a chronic autoimmune disorder, curable with replacement of the immune system with an allogeneic HSCT.

Multiple sclerosis (MS) is thought to be an autoimmune disease in which activated T-cells initiate a macrophage mediated destruction of CNS myelin. Bone marrow transplantation (BMT) is currently being evaluated in the treatment of MS in patients with aggressive disease activity. Autologous BMT could potentially reset the immune response to myelin antigens leading to immune tolerance and decreased disease activity. Allogeneic transplantation could reconstitute the immune system potentially arresting the progression of autoimmune disease. The purpose of this paper is to report a patient with MS who underwent allogeneic BMT for chronic myelogenous leukemia (CML) and showed continued evidence of active demyelinating disease by clinical and radiologic criteria over a period of two years. While this is only a single case report with inherent limitations, it suggests that the immune mediated destruction of CNS myelin in MS may not be prevented or aborted by immune system reconstitution, and is consistent with the idea that immune mediated tissue destruction in MS could be targeted against an abnormal antigen.

Patients diagnosed with ulcerative colitis (UC) are known to be at an increased risk of colorectal and liver cancers and leukemia. UC is an autoimmune disease, which may present a wider spectrum of cancers. We wanted to examine the risk of cancer in a large population of UC patients in order to reach high statistical power. A UC research database was constructed by identifying UC patients from the Swedish Hospital Discharge Register and cancer patients from the Cancer Registry. Follow-up of 27,606 UC patients hospitalized for the first time during the years 1964-2004 identified 2,058 patients with cancer. Standardized incidence ratios were calculated for cancer in UC patients by comparing to subjects without hospitalization for UC. The novel tumor sites in UC patients included small intestinal (carcinoid), pancreatic, breast and prostate cancers, nonthyroid endocrine gland tumors, non-Hodgkin lymphoma and multiple myeloma. A total of 11 sites showed an increased risk, which remained at 6 sites when tumors diagnosed in the year of UC hospitalization were excluded; even chronic myeloid leukemia was in excess. Cancer risks depended on the age at first hospitalization for UC. The SIRs for colon, rectal, liver and pancreatic cancers declined by age at hospitalization for UC, while for endocrine tumors the older patients were at higher risk. Our large study identified novel subsequent cancers in UC patients. However, some of these, including small intestinal carcinoids, prostate cancers and nonthyroid endocrine tumors, may be in excess because of intensified medical surveillance of the patients.
