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.

Acquired hypercoagulable states comprise a diverse group of clinical conditions that are associated with an increased risk of thrombosis. These clinical conditions include malignancy, diabetes mellitus, venous stasis, pregnancy, oral contraceptive use, lupus anticoagulant, postoperative state, immobilization, myeloproliferative disorders, and nephrotic syndrome. Recognition of these associations, possible underlying mechanisms, identification of high risk individuals, thromboembolic prophylaxis, and other clinical implications are discussed.

Bilateral symmetrical polyarthritis occurred in three patients (2 males and 1 female), with no previous history of inflammatory rheumatologic disease, given alpha-interferon for 1 1/2, 7, and 10 months as treatment of chronic non A-non B hepatitis, myelofibrosis, and thrombocytopenia with myeloproliferative disorder, respectively. Joint manifestations developed 1 1/2, 3, and 10 months after initiation of alpha-interferon in a dosage of 3.10(6) U three times a week, 4.5.10(6) U per day, and 8.10(6) U three times a week. Polyarthritis persisted following withdrawal of alpha-interferon in the two last patients of whom one had rheumatoid nodules and positive rheumatoid serology and the other had scleritis, exanthema, and negative rheumatoid serology. Erosive rheumatoid arthritis was diagnosed after 28 months and 12 months, respectively, in two patients who required systemic corticosteroids with antimalarials (1 case) or azathioprine after failure of methotrexate (one case). Follow-up in the third case (12 months) is too short to allow differentiation of systemic lupus erythematosus (ANA: 1/1500 H with anti-DNA antibodies 58 U/ml) and chronic autoimmune hepatitis. Reports of chronic inflammatory rheumatologic disease during alpha interferon therapy are exceedingly few in number. In the cases reported herein, alpha-interferon may have either triggered or revealed the joint disease. To prevent occurrence of this complication, exclusion from alpha-interferon therapy of patients with autoantibodies or a positive history for clinical evidence of immune dysfunction may be considered.

Hemapheresis has been used in a variety of clinical states, primarily for its ability to remove an offending component, likely be either plasma or cellular elements. We have reviewed 43 cases of therapeutic hemapheresis over the past two years at Veterans General Hospital. There were 20 cases of plasmapheresis, 7 cases of leukapheresis and 16 cases of thrombocytapheresis. Most of them had satisfactory and desirable effects except a few cases in therapeutic plasmapheresis. Among 20 cases of therapeutic plasmapheresis, all but 2 cases of systemic lupus erythrematosus had transient clinical improvement. Average decrease of leukocyte count in 11 procedures of leukemic patients was 37%. As for the myeloproliferative disorders with thrombocytosis, the average drop of platelet count was 41%. The side effects of therapeutic hemapheresis were not infrequent. There were 56 recorded side effects with one sudden death among 94 procedures. Hemapheresis is useful in certain clinical conditions but more judicious application should be considered.

A series of 122 consecutive patients with bone marrow fibrosis initially referred or categorized as idiopathic myelofibrosis is described. After a clinical and pathological review 14 patients were classified as postpolycythaemic myelofibrosis and 7 patients as a transitional myeloproliferative disorder. In 13 patients a diagnosis of hairy cell leukaemia was made, 3 patients had malignant lymphoma, 2 had malignant histiocytosis, and 1 patient had systemic lupus erythematosus with myelofibrosis. Two patients were excluded for further analysis owing to insufficient data. In the remaining 80 patients a diagnosis of idiopathic myelofibrosis was made. The clinical and laboratory findings in this series of patients are presented and compared to those in previous series. Infectious, cardiovascular, thromboembolic, and haemorrhagic complications were frequent, being recorded in 63%, 50%, 40%, and 33% of the patients, respectively. Various autoimmune phenomena were found in a proportion of the patients, but none had clinical evidence of connective tissue disease. Fifteen patients (19%) had a syndrome of acute myelofibrosis. The diagnostic criteria for this disease entity and its place within the spectrum of myeloproliferative disorders are discussed. In the present series acute myelofibrosis was found to encompass various transitional stages toward the evolution of acute leukaemia. It is proposed that acute or malignant myelofibrosis is considered as an acute variant of idiopathic myelofibrosis. Within this syndrome the acute variant seems to be far more common than previously recognized, which may also explain the marked clinical heterogeneity of the myelofibrosis/osteomyelosclerosis syndrome in this and most previous series.

We measured the calmodulin content in platelets in 13 normal persons and in 62 patients with hematological diseases. The level of platelet calmodulin was higher in patients with idiopathic thrombocytopenic purpura (ITP), systemic lupus erythematosus, myeloproliferative disorders, acute leukemia in a recovery phase, aplastic anemia, thrombosis and hypersplenism as compared to the controls. Among the patients with ITP, calmodulin was lower in responders than in nonresponders and those at the initial diagnosis. We also measured the volume, life-span and aggregation of the platelets and demonstrated a significant relationship between the calmodulin level and the platelet volume, and a negative relationship between the calmodulin level and platelet life-span, there was no correlation between the calmodulin level and platelet aggregation. We thus conclude that platelet calmodulin is inversely correlated with platelet turnover.

Venous thromboembolic diseases are of major importance with respect to morbidity and mortality. Therefore, efficient prophylaxis is essential. Indication for thromboprophylaxis has to be made individually: In high risk situations, especially in orthopedic surgery, every patient should receive medical prophylaxis, e.g. with heparin, in addition to other preventive measures such as the wearing of elastic stockings or physiotherapy until full mobilization. For high-risk patients having a history of recurrent venous thromboembolism or which are suffering from a thrombogenic disease (e.g. myeloproliferative disorder, especially polycythemia vera, paroxysmal nocturnal hemoglobinuria, systemic lupus erythematosus, homocystinuria) or a hereditary thrombophilia (e.g. deficiency of antithrombin III, protein S, protein C or APC resistance), prophylactic measures should be more generally applied. In these patients, risk factors (e.g. oral contraceptive medication) or risk situations (e.g. long-distance travelling by car or airplane) have to be avoided whenever possible. In inevitable risk situations (e.g. perioperative or peripartal period) prophylaxis is mandatory. It is generally limited to the period of elevated thrombogenic risk and is often effected by application of a low molecular weight heparin. Patients with a history of recurrent thromboembolic events despite elimination of all avoidable risk factors should get a lifelong prophylaxis, usually with oral anticoagulants.

We have presented a working hypothesis showing the possible interrelations between proliferative, aproliferative and autoimmune disorders that may follow infection with lymphotropic herpesviruses. Aproliferative disorders in this context may also indicate immune or hematopoietic deficiency. Although this hypothesis can currently be best documented with the lymphotropic viruses (herpesviruses as well as similarly HTLV and HIV), the model may apply as well--with certain variations--to other viral infections such as with hepatitis virus B or C with acute or chronic infectious diseases, post-infectious arthritis, aplastic anemia, and other autoimmune liver diseases, as well as neoplastic diseases (hepatocellular carcinoma, chronic lymphocytic leukemia). The working hypothesis as depicted in Figure 2 permits a preview of which combinations of symptoms may occur in an individual disease independent of its initial classification and what clinical testing should be done respectively, and it also permits certain prognostic considerations. The above-mentioned transitions or combinations of various disease patterns have been repeatedly described in the medical literature (to refer to only a few examples: APL and MPD, HD and MDS, SLE and aplastic anemia, SLE and Kikuchi's disease; 23, 80-83). Finally the hypothesis can ideally serve as the basis for future planning of clinical research.

In a prospective study of 22 patients with non-tumorous Budd-Chiari syndrome, four were found to have the antiphospholipid syndrome with no other cause of hepatic vein thrombosis. All four patients were young women. The antiphospholipid syndrome was secondary to systemic lupus in one case, to a "lupus-like disease" in another, and apparently primary in the remaining two cases. Two patients died. The other two are in good health on chronic oral anticoagulation. In our experience, the antiphospholipid syndrome is a frequent cause, after myeloproliferative disorders, of non-tumorous Budd-Chiari syndrome. In such patients, long-term anticoagulation may prevent recurrence or extension of thrombosis.

Side effects of long-term interferon (IFN) therapy for myeloproliferative disorders may be vasospastic Raynaud's attacks and lupus-like illness. The authors report on a woman with chronic myelogenous leukemia who experienced severe trophic lesions of the fingers after forty-nine months of IFN therapy. Digital artery occlusions could be proven arteriographically.
