HIV drug therapy often fails because of the appearance of multidrug-resistant virus. There are two possible scenarios for the outgrowth of multidrug-resistant virus in response to therapy. Resistant virus may preexist at low frequencies in drug-naive patients and is rapidly selected in the presence of drugs. Alternatively, resistant virus is absent at the start of therapy but is generated by re...

The most serious problem of nucleoside/nucleotide analogue therapy for hepatitis B virus (HBV) infection is the emergence of drug-resistant mutant virus. Here, we describe a patient with chronic hepatitis B infection with a complex drug-resistant mutant virus during sequential therapy with lamivudine (3TC), entecavir (ETV) and adefovir dipivoxil (ADV). The patient was a 52-year-old male with po...

Combination antiretroviral therapy reduces overall and liver-specific morbidity and mortality in coinfection with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) and represents the most beneficial pharmaceutical treatment intervention for most coinfected patients. Antiviral therapy for HCV infection is potentially organ- and life-saving but, in general, should be reserved for pat...

OBJECTIVE To evaluate whether or not highly active antiretroviral therapy is associated with carotid artery stiffness in human immunodeficiency virus-positive patients in Henan Province, China. METHOD Fifty human immunodeficiency virus-positive patients with at least a 5-year history of highly active antiretroviral therapy use and 50 human immunodeficiency virus-positive patients without a hi...

context viral hepatitis and the consumption of alcohol are recognized as important reasons for the development of liver disease throughout the world. it would also seem that chronic alcoholism causes more severe and rapid progression of liver disease in patients with chronic hepatitis c, leading to more frequent liver cirrhosis and hepatocellular carcinoma. evidence acquisition the data for thi...

chronic hepatitis c might lead to several immunological dysfunctions. studies have shown a positive association between hepatitis c virus (hcv) infection and psoriasis. these results suggest that the infection may be one of the triggering factors for the development or exacerbation of psoriasis. here, we present a case of chronic hcv infection with psoriasis who developed exacerbation of skin l...

800x600 hepatitis b virus (hbv) infection is the main cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma (hcc). several factors such as serum hbv dna level, genotype and specific viral mutations have been clarified to determine disease progression of chronic hepatitis b. among these, mutations can also occur in chronic hbv patients with antiviral treatment such as lamivudine the...

celiac disease is characterized by a gluten-induced damage of the small bowel in sensitive individuals that may cause malabsorption. non-intestinal inflammatory diseases may trigger immunologic gluten intolerance in susceptible people and the hcv virus may be considered as a suitable candidate. interferon therapy could precipitate symptom onset in subjects with silent celiac disease. in fact, s...

Human immunodeficiency virus (HIV) attacks the immune system and can cause acquired syndrome. Thankfully, antiretroviral therapy is highly effective, people infected with HIV live long lives proper adherence to therapy. One of important noninfectious complications development pulmonary arterial hypertension (PAH). This review will cover epidemiology, pathogenesis, clinical characteristics HIV-a...

The prevalence of Hepatitis C virus (HCV) is approximately 3% around the world. This virus causes chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. The effectiveness of interferon-α and ribavirin therapy is about 50% and is associated with significant toxicity and cost. Hence, generating new vaccines or drugs is an obligation. However, there is no vaccine available for clinical u...
