Hypogammaglobulinaemia and agranulocytosis:case report

Hypogammaglobulinaemia and agranulocytosis associatedwith the use of carbamazepine, occurred in a 63-year-old man.

The man had experienced a cerebral haemorrhagecomplicated by a grand mal seizure and had then takencarbamazepine 400mg twice daily. He also took lisinopril andatenolol to control his BP. Approximately 7 months after theepisode, he presented with anorexia, bodyweight loss, and acough. Haemophilus influenzae was identified in his sputumand tests showed panhypogammaglobulinaemia with absent Blymphocytes; at this time his granulocyte count was normal.

Lisinopril was substituted with amlodipine, and the dosageof carbamazepine was reduced to 100mg twice daily. By thefollowing month, the man had a fever, nausea, and a largeulcer on his lip; his WBC count was 1.4 x 109/L, with 0.5 x 109/Lgranulocytes. Carbamazepine was replaced by valproic acid.

The agranulocytosis was treated successfully with 3 days ofgranulocyte colony-stimulating factor therapy, and this wasfollowed by a resolution of the fever. The man was also treatedwith anti-infective agents. After approximately 3 months,mature B lymphocytes were detectable, and IgG, IgA, and IgMhad increased, but IgG2 was still reduced.
