Dr. Ossama Ashraf Ahmed is a distinguished professor of internal medicine, gastroenterology, and hepatology at Ain Shams University in Cairo, Egypt. Born on October 25, 1977, in Cairo, he completed his Bachelor of Medicine and Surgery (M.B.B.Ch) with honors from Ain Shams University in December 2001. He furthered his education and training at the same institution, culminating in his appointment as a professor in December 2019. Throughout his career, Dr. Ahmed has made significant contributions to the field of hepatology, particularly in the management and treatment of Hepatitis C Virus (HCV) infections. He co-authored a pivotal study titled "Sofosbuvir Plus Daclatasvir in Treatment of Chronic Hepatitis C Genotype 4 Infection in a Cohort of Egyptian Patients: An Experiment the Size of Egyptian Village." This research evaluated the efficacy and safety of a combination therapy in treating HCV genotype 4, a prevalent strain in Egypt. The study demonstrated a 96% sustained virologic response at week 12, highlighting the regimen's effectiveness. In another notable study, Dr. Ahmed investigated the "Impact of IL28B Gene Polymorphism on Efficacy and Safety of Direct Acting Antivirals in Hepatitis C Egyptian Patients." This research explored how genetic variations affect patient responses to antiviral treatments, providing insights that could lead to more personalized and effective therapies.
