RECURRENT ATTACKS OF HEMOLYTIC UREMIC SYNDROME

In 1955 Gasser and his co-workers [1] were the first to describe the so-called hemolytic uremic syndrome (HUS); since then, the number of reports has steadily increased. Some authors consider HUS as a unique syndrome [2], while others suggest that HUS is both heterogenic and heterogeneous [3]. It is generally emphasized that HUS never recurrs [4, 5]. However, this view should be reconsidered due to the numerous reports on a recurrent form of HUS [6-9], which is beginning to be recognized as an important subset or variant of this syndrome [10]. This report describes a case, where three similar recurrent episodes of hemolytic anemia, thrombocytopenia and uremia had occurred during the past eight years.
