Objective: To assess the rationale use of benzodiazepines among various departments in a multi-speciality hospital. Methods: A prospective study was conducted with a sample size of 200 for a period of six months. Data was collected from patients based on inclusion and exclusion criteria. Naranjo Adverse Drug Reaction Probability Scale and Drug Interaction Probability Scale (DIPS) were used as a study tool to measure the causality of adverse drug reactions and drug interactions. Based on the dosage of various benzodiazepines DDD was calculated and compared with WHO Anatomical Therapeutic Chemical (ATC) classification Defined Daily Dose (DDD). Results: BZD’s were mostly prescribed in males (74.5%) and married patients (86.5%) were more exposed to benzodiazepines compared to others. Lorazepam (70.1%) was found to be the most commonly used drug, mainly prescribed for sedation, followed by anxiety. DDD was calculated and majority of patients had DDD in accordance with WHO standard. Based on cost analysis, Clobazam was found to be the high cost and Lorazepam being the low-cost drug. The results of drug utilization evaluation of benzodiazepines study were compiled and reported to the respected department physician and their feedback was collected. Conclusion: The study showed a rational utilization of benzodiazepines and the negative outcomes of BZDs can be reduced by providing drug-related information to the prescribers and consumers.

Background Ever since AE was acknowledged as a potentially treatable cause of encephalitis, it has been increasingly recognised worldwide. Data suggests that these disorders are under-recognized, which calls for an increased awareness of the varying clinical, laboratory, electrophysiological and radiological presentations of the different types of autoimmune encephalitis. This cross-sectional observational study included all patients diagnosed with AE, who presented to a tertiary care centre from June 2016 to January 2021. Data were collected including patient’s demography, clinical, laboratory, radiological and electrophysiology studies, management and outcomes. Results 31 study participants were included, of which 13 patients were anti-NMDA antibody positive, 12 patients were anti-LGI1 antibody positive, 2 patients were anti-CASPR2 antibody positive, 2 were positive for dual positive status (anti-LGi1 and anti-CASPR2), and one each for anti-GABA-B and anti-GAD 65. There was a marginal male predilection with overall seizures being the most common symptom (68%) followed by behavioural disturbance (64.5%), and impairment of consciousness (32.3%). Patients with Anti-NMDA encephalitis were likely to be young females, with CSF pleocytosis, a more protracted hospital course with more chances of relapse and residual disease, while the patients with anti-Lgi1 encephalitis were likely to be older males with a shorter, less severe hospital course. Conclusion The present study detailed the demographic, clinical, imaging, laboratory and EEG characteristics of 31 AE patients from a tertiary centre. The findings concurred with the literature and demonstrate the diverse spectrum of clinical manifestations of patients with AE, present with.
