ABSTRACT:
FIELD OF THE INVENTION
This invention relates to hyperthermic treatment of hepatitis C.
BACKGROUND OF THE INVENTION
Injected drug users are the largest group of people with hepatitis C infection. People who received a blood transfusion or kidney transplant before a diagnostic test became available form another large group of those infected.
Since human immunodeficiency virus (HIV) is also common among injected drug users and is transmitted sexually, about forty percent of HIV infected patients are co-infected with HCV. Various types of HIV such as HIV-1 and HIV-2 exist. Hepatitis C virus occurs in six known genotypes and more than fifty subtypes. The hepatitis C virus is harbored in the liver and most people infected with HCV eventually will develop cirrhosis or liver carcinoma. HCV can cause an acute or chronic infection. In chronic infection, the infected person can exhibit signs of chronic hepatitis or be a chronic asymptomatic carrier.
Current treatments for hepatitis C include interferons and other pharmaceuticals. However, because these treatments are not effective for all patients, improved methods for treating hepatitis C are being sought.
SUMMARY OF THE INVENTION
The invention provides a method for treating a patient infected with hepatitis C virus (HCV) comprising raising the core temperature of the patient and then returning the core temperature of the patient to normal at least one time. The core temperature is raised to a temperature range, a duration, and a number of times sufficient to reduce or eliminate the patient's viral load of HCV. In another embodiment of the invention, the patient is co-infected with the human immunodeficiency virus (HIV).
The invention also provides a method for treating a patient infected with HCV comprising raising the temperature of the patient's liver and then returning the temperature of the patient's liver to normal at least one time. The temperature of the patient's liver is raised to a temperature range, a duration, and a number of times sufficient to reduce or eliminate the patient's viral load of HCV.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
