A novel combination of bortezomib, lenalidomide, and clarithromycin produced stringent complete response in refractory multiple myeloma complicated with diabetes mellitus - clinical significance and possible mechanisms: a case report.

Background: In general, dexamethasone is a required component drug in various combination chemotherapies for treating multiple myeloma, and its efficacy has been widely recognized. However, administration of dexamethasone is known to cause various adverse effects including hyperglycemia which requires insulin therapy. During the course of treatment, we developed a novel effective dexamethasone-free combination regimen and evaluated it for its effect in multiple myeloma.

Successful treatment in a case of Propionibacterium acnes-associated sarcoidosis with clarithromycin administration: a case report.

Introduction: Sarcoidosis is recognized as a multiorgan disorder characterized by the presence of non-caseating granulomas in the involved tissues. It has been suggested that sarcoidosis might be due to the exposure to infectious or non-infectious agents in genetically susceptible individuals. In particular, Propionibacterium acnes and Mycobacterium tuberculosis have been considered causative microorganisms.

Complete Remission of Methotrexate-Related Epstein-Barr-Virus-Associated Hodgkin-Like Lymphoma following Withdrawal of MTX Coupled with Clarithromycin Administration.

Patients with rheumatoid arthritis (RA) are known to develop lymphoproliferative disorders (LPDs) during the course of illness, particularly in cases treated with methotrexate (MTX) for long periods. We describe a case of MTX-related Epstein-Barr-virus-(EBV-) associated LPD resembling Hodgkin's lymphoma (HL), in which a dramatic complete remission was achieved after withdrawal of MTX coupled with clarithromycin (CAM) administration. Withdrawal of MTX coupled with CAM administration seemed to be effective for treating MTX-related EBV-associated LPDs.
