Vitamin D deficiency impairs rituximab-mediated cellular cytotoxicity and outcome of patients with diffuse large B-cell lymphoma treated with but not without rituximab.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc in the context of cellulite.

To investigate the impact and mechanisms of vitamin D deficiency (VDD) on the outcome of elderly patients with diffuse large B-cell lymphoma (DLBCL).

Who Took Part

According to the abstract, 60 patients were involved.

By PubMed's age tags, the people studied were middle-aged adults, older adults and people over 80, both men and women.

Three hundred fifty-nine pretreatment 25-hydroxyvitamin D3 (25[OH]D3) serum levels from the RICOVER-60 study (Six Versus Eight Cycles of Biweekly CHOP-14 With or Without Rituximab in Elderly Patients With Aggressive CD20+ B-Cell Lymphomas) and 63 from the RICOVER-noRTh study (an amendment to the RICOVER-60 study in which patients received six cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone administered at an interval of 2 weeks plus two cycles of rituximab [R-CHOP-14], but without radiotherapy) were determined by chemoluminescent immunoassay.

How the Study Was Run

The researchers set it up as a randomized study.

The patients were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

Rituximab-mediated cellular cytotoxicity (RMCC) was assessed by lactate dehydrogenase release assay of CD20+ Daudi cells.

What Was Measured

The subject headings attached to it are Antibodies, Monoclonal, Murine-Derived, Antineoplastic Agents, Antineoplastic Combined Chemotherapy Protocols, Calcifediol, Cyclophosphamide, Doxorubicin and Lymphoma, Large B-Cell, Diffuse.
