Entecavir is new drug for chronic hepatitis B treatment
Entecavir je nový lék na chronickou hepatitidu B
Protivirová léčba chronické hepatitidy B interferony byla v poslední dekádě významně rozšířena o syntetické nukleosidy a nukleotidy, které se podávají per os. Prvním lékem byl lamivudin (100 mg/den), druhým adefovir dipivoxil (10 mg/den) a v současné době probíhají rozsáhlé klinické studie s entecavirem (0,5 mg/den), což je guanosinový analog s velkou a selektivní protivirovou aktivitou proti viru hepatitidy B. Je indikován u HBeAg pozitivních i negativních pacientů s chronickou hepatitidou B a známkami virové replikace. Při porovnání výsledků léčby entecavirem a lamivudinem nastalo po 12 měsících léčby významné histologické, virologické a biochemické zlepšení, které bylo vyšší u entecaviru. Bezpečnost a snášenlivost léčby byly u obou léků podobné, a zatím nebyla zjištěna po léčbě entecavirem žádná rezistence proti viru hepatitidy B.

Overview
The antiviral treatment of chronic hepatitis B by interferons was significantly extended in last decade by synthetic nucleosides and nucleotides which are given perorally. Lamivudin (100 mg/day) was the first, adefovir dipivoxil (10 mg/day) was the second drug, and nowadays extensive clinical trials are continuing with entecavir (0.5 mg/day) which is an analogue of guanosine with high and selective antiviral activity against hepatitis B virus. It is given to HBeAg positive and negative patients with chronic hepatitis B and serological markers of viral replication. In comparison of entecavir to lamivudine treatment there was significantly higher histological, virological and biochemical improvement in entecavir. Safety and tolerance profil was similar in both drugs and no antiviral resistence to hepatitis B virus was meanwhile observed during 12 moths entecavir treatment.
