In vivo T-cell immune response against anaplastic lymphoma kinase in patients with anaplastic large cell lymphomas.

Background And Objectives: Anaplastic lymphoma kinase (ALK) oncogenic fusion proteins, expressed in about 60% of anaplastic large cell lymphomas (ALCL), are tumor-specific molecular targets for such a malignancy. One of the promising ALK-targeted therapeutic options is cancer vaccination. In this study, we investigate whether ALK is a tumor-associated antigen suitable for immune interventions.

Prevalence of gallstones in patients with primary immunoglobulin deficiency. Evidence for lack of association.

In the early 1970s an increased prevalence of gallstones was reported in adults and children with immunoglobulin deficiency. As the advent of ultrasonography has largely changed the diagnostic approach to gallstones, we have reevaluated the prevalence of cholelithiasis in a group including 37 patients with common variable immunodeficiency and seven patients with other forms of primary immunodeficiency. All patients were receiving intravenous gammaglobulin replacement since 1983 or, in more recent cases, soon after the diagnosis was made, and therefore had relatively few infections.
