Assessment of Haematological Parameters in Patients under Carbamazepine Antiepileptic Drug Treatment

Nesreen Hassan Ali, Amira Ahmed K. Humeida


AIM Carbamazepine is iminostilbene derivative used as an antiepileptic drug against partial and tonic-clonic seizures and is also used in trigeminal neurologic and bipolar affective disorders. According to previous studies, carbamazepine is associated  with a wide range of haematological toxicities including leucopenia, reduced haemoglobin and red blood cell count,  and thrombocytopenia.

This study was conducted to establish the effect of carbamazepine as an antiepileptic drug in haematological parameters in patients using it for different durations.

METHOD In this study, 50 individuals were recruited as the study group and 50 individuals as the control group. Seventeen patients were female while 33 were male in the study group. Twenty-two were female and  28 were male in the control group. In both groups age-range was  15-70 years. We included patients under treatment for at least one month. Subjects with neurological deficits, haematological deficits, or history of drugs/alcohol abuse at recruitment were excluded from the study. Route of administration was oral. Blood samples (2.5 ml each sample) were collected from all patients and controls in Ethyelene diamine tetra acetic acid (EDTA) blood tubes, Full Blood Counts (FBCs) were carried out using automated Huma count 30 cell counter.

RESULTS  In this study administration of carbamazepine at different doses, different duration and with different severity of disease produced slight differences in mean haemoglobin, haematocrit and white blood cell count with p value > 0.05. The mean platelet counts were also within normal range in all patients. Addition of folic acid to carbamazepine therapy did not produce any clinically significant changes in haematological parameters. Our study did not reveal any significant relationship between severity of disease, duration or dose of carbamazepine and changes on FBC results.

CONCLUSION Carbamazepine had no significant difference in FBC parameters among epileptic patients who used it as treatment.
