Molecular Detection of Influenza A(H1N1)Pdm09 Virus Among Chronic Kidney Disease Patients: A Peripheral Blood Sample Approach and Assessment of the Associated Risk Factors

Abstract

Introduction: Chronic kidney disease (CKD) is a progressive loss of functional nephron characterized by various risk factors. Influenza virus has been found to cause rhabdomyolysis, which is toxic to the kidneys and can initiate or worsen CKD. This study aims to investigate the frequency and molecular detection of Influenza A(H1N1)Pdm09 Virus gene among CKD patients attending University of Maiduguri Teaching Hospital, Nigeria.Materials and Methods: Peripheral blood samples were collected from 150 CKD patients. One-step RT-PCR was performed for detection of influenza virus using the Centers for Disease Control and Prevention protocol. Relevant clinical data were collected in standardized questionnaires from each patient, and medical history was obtained from their hospital records.Results: Conventional PCR analysis revealed that 16% of the CKD patients tested positive for Inf A/Pdm H1N1. The virus frequency was found to be higher among patients in CKD stage 5 (end-stage CKD) and lower in CKD stage 3 (moderate CKD). Additionally, female CKD patients and those in the age group of 55-64 years showed a higher susceptibility to Inf A/Pdm H1N1 infection.Discussion: The study provides evidence of the presence of Inf A/Pdm H1N1 in CKD patients, aligning with previous research showing its involvement in kidney disease aggravation. CKD patients often exhibit immune dysregulation, which might facilitate the virus's invasion and persistence. Conclusion: This study provides evidence of an association between Influenza A(H1N1)Pdm09 viraemia and decreased kidney function among CKD patients. The findings highlight the importance of monitoring and preventing influenza infection in CKD patients to prevent further kidney damage.
