We report an association between histologically confirmed progressive multifocal leukoencephalopathy (PML) and an extremely rare humoral immunodeficiency disease, Franklin disease. In our patient, clinical presentation has been typical and prompted us, together with radiological findings, to perform a brain biopsy to confirm the diagnosis even if there was(More)
Cryoglobulins are immunoglobulins that precipitate in serum at temperatures below 37°C and resolubilize upon warming. The clinical syndrome of cryoglobulinemia usually includes purpura, weakness, and arthralgia, but the underlying disease may also contribute other symptoms. Blood samples for cryoglobulin are collected, transported, clotted and spun at 37°C,(More)
BACKGROUND Monoclonal gammopathies encompass a wide range of diseases characterized by the monoclonal expansion of a B-cell clone. Despite emerging therapeutic strategies, chances of survival of patients who are affected are still scarce, which implies that new tools are necessary not only for the diagnosis but also for the follow-up of patients affected by(More)
OBJECTIVES A new rapid, automatic, and sensitive screening test useful to detect cryoglobulins in serum samples is proposed. DESIGN AND METHODS The increase of turbidity during the cryoglobulin aggregation was monitored spectrophotometrically in sera from 400 patients with clinical evidence of cryoglobulinemia related disorders and 100 controls.
