HCV in 2006 ()
• I am seeing increasing numbers of patients from Bangladesh and Pakistan with advanced liver disease from HCV

HCV in 2006 ()Are we missing something ?
• The government tells us that this is a drug users disease
• I am seeing non-drug users with liver cancer secondary to HCV
• Are we missing something important ?

Treating the non-1 patientCan we use shorter durations of therapy ?
• Pilot study of 14 weeks therapy in patients with an early virological response
• Used Peg-Intron 1.5g/kg + Normal dose ribavirin

HCV – Who should we treat?(Opinion based medicine)
We should NOT treat active drug users
They will not comply
They will get reinfected
(They are not worth it)

HCV in drug users
• Drug users infect others !
• Not treating drug users encourages the spread of HCV

Therapy for HCV Summary (I)
• The natural history of HCV is of glacial progression
• Many patients will eventually develop cirrhosis
• Delaying therapy may reduce response rates
![Page 36: Hepatitis C When, how and which patients should be treated](https://reader035.vdocuments.us/reader035/viewer/2022062807/56815004550346895dbdd2d4/html5/thumbnails/36.jpg)
Therapy for HCV Summary (II)
• We have effective therapies available and these can be given to ALL patients with chronic HCV
