🌼 على الرغم من وجود ال Viral interference
.واللي عبارة عن Superinfection- resistance
بمعنى انو اذا دخل الفايرس للخلية يصير Down regulation of receptor
بالتالي تكون الخلية ماعاد تتأثر بفايرس اخر اذا كانت مصابة بالفايرس

بس فيه حالات يكون ال Patient متعرض
لل HBV & HCV في نفس الوقت ؟

مالسبب ؟

السبب انو الكبد يتكون من الالاف الخلايا
فالفايرس B يصيب خلية و الفايرس C يصيب خلية اخرى غير مصابة ..

🌷 There are 6 genotypes of hepatitis C virus ..

🌷 the genotype in middle-east including Arabic country : Yemen , Egypt and so on Is Genotype 4⃣

🌷 we can't develop a vaccination for Hepatitis C virus due to presence of variable Quasispecies .. which change it's antigen خيرااات

🌷The presence of Anti- HCV IgM is not useful to determine if it is acute, chronic or either cured infection ( due to Quasispecies)

🌷 We must do RT-PCR to confirm the results

🌷 Both Acute and Chronic infection present HCV DNA .. But note
🍃 Acute infection >> rised ALT
🍃 chronic infection >> fluctuating ALT
