ABSTRACT
Comorbid alcohol dependence is common in patients with schizophrenia and is associated with a variety of serious adverse consequences. Although case reports exist concerning the positive impact of lamotrigine addition on clozapine treatment in resistant schizophrenia, a review of the literature fails to document any evidence regarding a combination of the two in the treatment of patients with schizophrenia and comorbid alcohol dependence. In the present study, we present three cases in which patients with resistant schizophrenia and comorbid alcohol use disorder were given lamotrigine to augment clozapine. Our findings suggest that clozapine plus lamotrigine may be helpful in reducing alcohol consumption and craving among patients with schizophrenia and comorbid alcohol dependence.

Increased oxidative stress has been speculated to be one possible mechanism of ethanol toxicity. This study evaluates malondialdehyde (MDA) and protein carbonyl content in serum as markers of oxidative stress and DNA damage in lymphocytes in the same patients with chronic alcoholism. Patients with chronic alcoholism showed a significant increase in MDA levels and protein carbonyl content of their serum as compared with non-alcoholic control subjects. Increases in endogenous and H2O2-induced DNA damage were also observed in lymphocytes of patients with chronic alcoholism. In addition, there were significant correlations between endogenous and H2O2-induced DNA damage and serum MDA or protein carbonyl content in patients with chronic alcoholism. These results clearly indicate the presence of oxidative stress in patients with chronic alcoholism.
