Case report: Dialysis-associated hypotension in patients with eosinophilia

Hypotension is an important complication during haemodialysis, which is induced by many factors. Two patients complained of chest discomfort accompanied by hypotension during haemodialysis. The blood pressure of these patients fell with the numbers of eosinophils throughout the dialysis sessions. Reducing the eosinophilia by the administration of a steroid and an antihistaminic agent led to a significant improvement of hypotension during dialysis. These two cases suggest that the eosinophil might be an initiator of the cytokine network, ultimately releasing vasodilators, and thus is a cause of hypotension during haemodialysis.
