The clinical and laboratory findings in seven female patients with primary autoimmune diseases, one female patient with lymphoplasmacytoid (LP) immunocytoma and IgM paraproteinemia, and two male patients with multiple myeloma are described. The common denominator in all patients was a lupus anticoagulant or a closely related coagulation disorder. Recurrent thrombosis was observed in six patients with autoimmune diseases and in two patients with malignant monoclonal gammopathies. Other clinical manifestations included cerebral disorders (four patients with autoimmune disease/two patients with monoclonal gammopathy), repeated obstetric complications (6/1), asymptomatic valvular heart disease (6/1), renal dysfunction (6/2), hepatic involvement (2/2), and arthropathy (2/0). Laboratory investigations revealed a biologic false-positive serological test for syphilis in six patients with autoimmune disease and one with monoclonal gammopathy, antinuclear antibodies (4/0), antibodies against DNA (4/1), and a positive direct Coombs test (3/1) which was accompanied by hemolytic anemia in two patients (1/1). Additionally slight leukocytopenia (2/1) and thrombocytopenia (6/2) were observed; abnormal bleeding was only seen in one patient with severe thrombocytopenia. Other complications characteristic of LP immunocytoma or multiple myeloma were missing. The obvious similarities between the patients with autoimmune diseases and the patients with malignant monoclonal gammopathies suggest analogous pathogenetic mechanisms.(ABSTRACT TRUNCATED AT 250 WORDS)

The 48-year-old female patient was sent to our clinic for further evaluation of a spontaneous decrease of prothrombin- and prolongation of the bleeding-time. She presented in good conditions with an enlargement of cervical lymphnodes and the history of a monoclonal plasmacyte dyscrasia. The laboratory results revealed a pronounced decrease of prothrombin-time, a prolonged activated partial thromboplastin-time, a decrease of factor VII and X activity and a light chain paraprotein. The histological examination of the bone marrow led to the diagnosis of an immunocytoma and a medullar amyloidosis. For the aim of influencing the coagulopathy the patient was treated with chemotherapy. However, she developed severe bleedings. Further haemostaseological tests presented an amyloidosis-associated decrease of factor VII and X, an acquired von Willebrands disease, an acquired thrombozytopathy and a lupus-like anticoagulans. Under substitution of factor VIII-von Willebrand-factor-complex and chemotherapeutic treatment a stabilisation over several years was achieved till the patient died due to an amyloid-associated acute pancreatitis.

The antiphospholipid syndrome (APS) was described in 1983 as a clinical entity characterized by venous and arterial thrombosis, thrombocytopenia, and recurrent fetal loss. The serological markers of APS are antiphospholipid antibodies (APLA) directed mainly against anionic phospholipids, usually cardiolipin but also phosphatidylserine. Some APLA exhibit lupus anticoagulant activity. Monoclonal gammopathy sometimes occurs with the presence of autoantibodies. In this paper, we describe a patient with the diagnosis of immunocytoma with an IgM, kappa paraprotein with apparent specificity against anionic phospholipids, and lupus anticoagulant activity, but no clinical signs of APS. We describe in this patient the presence of a high titer of monoclonal APLA, which does apparently not induce the clinical symptoms of APS. This might be indicative for the presence of pathogenic and nonpathogenic antiphospholipid antibodies.
