简要总结
Schizophrenia is a chronic disorder associated with wide range of manifestations in several psychopathological dimensions such as positive, negative, disorganized, cognitive and affective symptoms. Up to 2/3rd of patients achieve good outcomes with antipsychotic treatment whereas 1/3rd show poor outcome. Thus, 30% to 40% of patients have Treatment Resistant Schizophrenia (TRS) characterized by inadequate response to treatment with two or more trials of dopaminergic antipsychotics (> 600 chlorpromazine equivalents); and illness duration more than 2 years. The antipsychotic Clozapine is the drug of choice for management of TRS. Many patients however do not respond to Clozapine monotherapy and require to be administered adjunctive treatments. They have high risk of bioenergetic and cognitive dysfunction. Acetyl-L-carnitine is involved in the bioenergetic pathways and it may be beneficial in cognitive dysfunction. The aim of the study is to assess therapeutic efficacy of Acetyl-L-Carnitine as an augmenting agent in clozapine resistant schizophrenia. 78 participants will be recruited using consecutive purposing sampling in a hospital based prospective, parallel group, open label study. Group I (n=39) will be given clozapine ± other antipsychotics + acetyl-L-carnitine and Group II (n=39) will be given clozapine ± other antipsychotics + placebo. The sociodemographic and clinical data will be recorded. Primary outcomes of treatment (efficacy of treatment as assessed by severity of symptoms and functioning) will be assessed on Positive and Negative Syndrome Scale (PANSS), Clinical Global Impressions Scale (CGI), Global Assessment of Functioning (GAF) and Montreal Cognitive Assessment (MoCA). Secondary outcomes will be assessed for antipsychotic side effects on Abnormal Involuntary Movement Scale (AIMS) and Barnes Akathisia Rating Scale (BARS), adverse drug effects of ALC on adverse event scale and cost effectiveness. Data thus extracted will be analyzed by appropriate statistical methods with P value ≤0.05 being statistically significant.
