Clozapine-associated neutropenic enterocolitis
1Department of Internal Medicine, College of Medicine, University of Iowa, Iowa City 52242.
Summary
Clozapine, used for treatment-resistant schizophrenia, can cause agranulocytosis. This case report details a rare instance of neutropenic enterocolitis developing after clozapine-induced agranulocytosis.
Area of Science:
- Pharmacology
- Gastroenterology
- Psychiatry
Background:
- Clozapine is reserved for treatment-resistant schizophrenia due to the risk of agranulocytosis.
- Potential side effects of clozapine may be underreported due to its restricted use.
Observation:
- A male schizophrenic patient developed agranulocytosis.
- Following agranulocytosis, the patient subsequently developed neutropenic enterocolitis.
Findings:
- This case represents the first reported instance of neutropenic enterocolitis associated with clozapine-induced neutropenia or agranulocytosis.
- The study reviews clozapine's history, side effect profile, and the pathophysiology of neutropenic enterocolitis.
Implications:
- Highlights a previously undocumented severe adverse event linked to clozapine therapy.
- Suggests the need for increased vigilance regarding gastrointestinal complications in patients on clozapine, especially those with neutropenia.
