A patient with IgM-secreting B-cell lymphoma developed demyelinating peripheral neuropathy, nodular regenerative hyperplasia of the liver, coagulopathy, and terminal miliary lymphomatous spreading. Serologic auto-antibody activities directed against myelin associated glycoprotein, prothrombinase complex (i.e. lupus anticoagulant) and smooth muscle cells were detected. It is suggested that there is a link between the IgM gammopathy, the immunological abnormalities and the various clinico-pathological conditions.

Recent reports strongly suggest an association between a laboratory picture of autoimmunity in the absence of clinical signs and symptoms and the recurrence of spontaneous pregnancy loss. This association seems particularly strong when circulating lupus anticoagulant is present and has therefore been called the circulating lupus anticoagulant syndrome. We present four patients with this syndrome who in addition to the asymptomatic autoimmune laboratory picture were also found to exhibit a distinct IgM gammopathy. In view of earlier reports that implicated IgM in poor pregnancy outcome, particularly in association with systemic lupus erythematosus, it is suggested that all patients with circulating lupus anticoagulant syndrome be evaluated for an IgM gammopathy. A fraction of IgM may be detrimental to development and growth of the normal fetal placental unit and may thus be implicated in repeated early pregnancy loss.

The plasma of a patient with myasthenia gravis had strong lupus anticoagulant activity and his IgM paraprotein displayed non-specific inhibition to coagulation factors IX, XI, XII, prekallikrein, and high molecular weight kininogen. He was placed on prednisolone, which resulted in improvement in his myasthenic symptoms, but the prolongation of APTT and macroglobulinemia remained. Double filtration plasmapheresis successfully decreased the serum IgM level from 1,190 mg/dl to 375 mg/dl and APTT improved from 58 s to 38 s. Myasthenia gravis is frequently associated with other autoimmune diseases, but the association with lupus anticoagulant and IgM gammopathy is rare.

The list of multisystem diseases involving both kidney and skin is long and includes immunologic disorders like systemic lupus erythematodes, a broad variety of vasculitides, metabolic disorders like diabetes mellitus, and infectious diseases. The present work describes the first case of renal failure due to Schnitzler's syndrome, a rare entity characterized by the association of generalized chronic urticaria, monoclonal IgM gammopathy, and osteosclerotic lesions. The described patient experiences improvement of renal function after treatment with the chimeric anti-CD20 antibody rituximab, indicating that the impairment of renal function might be mediated by B-lymphocytes. Renal insufficiency is known to be a potential complication of hypocomplementemic urticarial vasculitis. The present case reveals that it can occur in normocomplementemic urticarial vasculitides as well. Schnitzler's syndrome is a rare but probably underdiagnosed syndrome. It should be considered in the differential diagnosis of rash and coincidental renal failure of unknown origin. Immunofixation of immunoglobulins constitutes the crucial diagnostic step, since monoclonal gammopathy is a constant clinical sign in this entity.
