[Recurrences of agranulocytosis (author's transl)]

Since agranulocytosis is in principal a curable condition with modern treatment, recurrences must be reckoned with in sensitized patients. They are relatively frequent. Recurrence occurred in eight of 17 patients. One patient had three recurrences, the last one 18 years after the first. In an Italian woman nine recurrences due to aminophenazone occurred within six years. Since sensitization does not disappear spontaneously, a recurrence may also occur in patients who have had one episode of agranulocytosis. Sensitizing drugs must be strictly avoided to prevent such recurrences: their presence in drug mixtures must be guarded against. But once a patient is sensitized he may react with agranulocytosis to various types of drugs.
