Objective: To determine the frequency of depression in Hepatitis-C patients and its association clearance of HCV. Methods: It is cross sectional study that was conducted between 1st July to 31st December, 2020, at National Institute of Liver and Gastrointestinal Diseases (NILGID), Dow University of Health Sciences (DUHS). Both male and female patients aged 18 to 60 years presenting with Hepatitis-C PCR positive or had received DAA for three months and became PCR negative were included in this cross sectional study. Depression was analyzed by Hamilton Depression Rating Scale (HDRS). Mean and standard deviations were calculated and analyzed. Results: Total 210 patients were included in this study, with mean age 36.06±10.11 years. Depression was present in 118 (56.2%) patients. Among patients with HCV PCR positive depression present in 63 (30.0%) patients while in HCV PCR negative 55 (26.0%) patients. Similarly, depression in HCV PCR positive male patients, aged ≤40 years 80 (38.1%) and in HCV PCR negative 56 (26.7%) patients. Conclusion: Patients with chronic Hepatitis-C commonly suffer from depression. However, our study found no significant difference with change in PCR status at 12 weeks. doi: https://doi.org/10.12669/pjms.38.1.4788 How to cite this:Khuhro Q, Shaikh H, Washdev, Hashmi S.

Background: Neurobiology of schizophrenia involves impairment of glutamatergic neurotransmission. In this context, polymorphism in glutamate Ionotropic receptor a-amino-3-hydroxy-5-methyl-4-propionic acid (AMPA) type subunit 1 encoded by Glutamate Ionotropic Receptor AMPA Type Subunit 1 Gene (GRIA), (rs1127386, G/A) can be considered as a substantial contributor in pathogenesis of schizophrenia. Therefore, a pilot study was planned to find out if the single nucleotide polymorphism of GRIA (rs1127386, G/A) is a risk factor for schizophrenia in the population of Pakistan. It maps at 5q33, a schizophrenia susceptible locus as per genome-wide association studies. Methodology: Following Diagnostic and Statistical Manual 5 (DSM 5) criteria guidelines, 50 schizophrenia cases were incorporated in this case-control study and 51 controls, individuals without any psychiatric illness. The sternness of illness was figured out using positive and negative syndrome scale score (PANSS) score. Genomic DNA was extracted from blood, and further analysis was done on gel electrophoresis after conducting ARMS (amplification refractory mutation system) PCR. Frequencies of reported genotype and allele within both groups were determined using the chi-square test. Results: Statistically significant difference was not found in genotype and allele frequencies of (rs1127386, G/A) (p>0.05) between cases and controls in the study population. The severity status of the disease was also independent of the polymorphism (p>0.05). Conclusion: This pilot study specifies that polymorphism rs1127386 is not a risk factor for schizophrenia, at least in the Pakistani population.
