ABSTRACT
INTRODUCTION: Hydroxychloroquine (HCQ) is most frequently used in the treatment of systemic inflammatory diseases. Cardiac complications of anti-malarial drugs are uncommon, and most of the time are the result of a long-term exposition. In this case, cardiotoxicity is the consequence of the lysosomal dysfunction and the result of intracytoplasmic granular material inclusions. CASE REPORT: We report a 77-year-old woman who presented a very early and reversible cardiotoxicity, probably related to the quinidine like effect of the HCQ, 10 days after initiation of therapy for Whipple endocarditis. CONCLUSION: We discuss the different mechanisms of cardiotoxicity of anti-malarial drugs and their clinical manifestations.

The case of 53-year-old man who suffered from chronic lymphocytic leukemia since 1993 was presented. In the 6th year of treatment fludarabine was administered. Few days after administration of drug the patient developed watery diarrhoea not responding to treatment. We excluded both infectious etiological factors and infiltration of intestine in course of chronic lymphocytic leukemia. Histopathological examination with monoclonal antibodies and periodic acid-Schiff stain (PAS) revealed Whipple's disease as the reason of enteropathy. During 6 months diarrhoea caused extreme dyselectrolitemia, renal insufficiency and finally death of the patient.
