Treatment of chronic

These results suggest a potential role for anikioguanidine in the future treatment of chronic diabetes compHcations. 

Antibiotic LL-E19020a and LL-E19020P are described as useful agents for the treatment of chronic respiratory disease, fowl cholera, and necrotic enteritis in birds (76) and as anthelmintics in monogastric and mminant animals (28). 

Busulfan was used for the treatment of chronic myeloid leukemia and polycytemia vera. 

BFNs are classified into three groups a, (3, and y, and the different classes are produced from different cell types. Recombinant BFN-a is used in the treatment of chronic hepatitis B and C. 

Cytokines and biological response modifiers represent a broad class of therapeutic agents that modify the hosts response to cancer or cancer therapies. The enormous body information about their clinical uses and their side effects is beyond the scope of this essay that can only give illustrative examples. For an up-to-date information the reader can resort to reference [5]. As many as 33 different interleukins are known and the list continues to grow IL-2 used in the treatment of kidney cancer is one example. Interferon alpha is used for chronic myelogenous leukeia, hairy cell leukaemia and Kaposi s sarcoma. Interferons are also used in the treatment of chronic infections such as viral hepatitis. Tumor necrosis factor (alpha), G/GM/M-CSF, and several other cellular factors are used in treatment of various cancers. Many of these cytokines produce serious side effects that limit their use. 

Interferon alfacon-1 (Inferax ), interferon alfa-2b (IntronA ), and interferon alfa-2a (Roferon -A) are applied in the treatment of chronic hepatitis B and C and some malignancies, especially hairy cell leukemia. IFN-a proteins induce the expression of antiviral, antiproliferative and immunomodulatory genes. 

Interferon gamma-lb (Imukin ) is used to reduce the incidence of infections in the treatment of chronic granulomatosis. 

Zafirlukast and zileuton are used in the prophylaxis and treatment of chronic asthma in adults and children older than 12 years. Montelukast is used in the prophylaxis and treatment of chronic asthma in adults and in children older than 2 years.

Bismudi subsalicylate is used in combination witii otiier dru > to treat gastric and duodenal ulcers caused by H. pylori bacteria Mesalamine is used in the treatment of chronic inflammatoiy bowel disease Misoprostol is used to prevent gastric ulcers in those taking aspirin or nonsteroidal anti-inflammatory dragp in high doses for a prolonged time Olsalazine is used in the treatment of ulcerative colitis in those allergic to sulfasalazine. Sulfasalazine is used in the treatment of Crohn s disease and ulcerative colitis. Sucralfate is used in the treatment of duodenal ulcer.

HCV drugs with a direct antiviral mode of action are needed for the treatment of chronic HCV infection. The NS3 protease, NS3 heficase (which localizes to the carboxy-terminal domain of NS3 and catalyzes the unwinding of the double stranded RNA in a 3 to 5 direction (Tai et al. 1996)), and NS5B RNA polymerase... 

Adefovir in its prodrug form, adefovir dipivoxil, is indicated in the treatment of chronic HBV infections (chronic hepatitis B), where, if administered orally as a single dose of lOmg per day, HBV DNA load is reduced significantly (>31ogio) over a 1- or 2-year period (Hadziyannis et al. 2005). 

In addition to the NRTI lamivudine (3TC) and the NtRTI adefovir dipivoxU and tenofovir disoproxil fumarate (which has been recently licensed for the treatment of chronic hepatitis B), two other nucleoside analogues, that is, entecavir and L-dT (tel-bivudine) (Fig.4aa), have been licensed for the treatment of HBV infections. Two other compounds 3 -Val-L-dC (valtorcitabine) and L-FMAU (clevudine) (Fig. 4aa) are in clinical development for the treatment of HBV infections, and yet two other compounds, that is, racivir and elvucitabine (Fig. 3), yield potential for the treatment of both HBV and HIV infections.

Abstract In 2007, the world celebrated the 50th anniversary of the discovery of interferon (IFN) by Isaacs and Lindemnann. Subsequently, the IFN-a gene was cloned, fully sequenced and IFN-a was produced in recombinant form. Recombinant IFN-a is now used as the basis for treatment of chronic hepatitis C virus infection and can also be used to treat certain forms of chronic hepatitis B virus infections. IFNs have also been used in other viral infections, although with less success. The antiviral mechanisms of IFNs are reviewed in this chapter as well as the utility of IFNs in the treatment of persistent viral infections. 

Different forms of IFN-a have been available for the treatment of chronic hepatitis B and C, including IFN-a2a and IFN-a2b. The administered dose was 3-5 megaunits three times a week subcutaneously.
