Gender differences in the treatment of HIV infection
Abstract
In recent years, following the successful development of highly active antiretroviral therapy (HAART), several studies have evaluated potential differences between men and women in the course of HIV infection, response to treatment, and drug pharmacokinetics. A slightly lower HIV viral load in untreated women has been reported, particularly at higher CD4+ levels, but this difference does not translate into gender-specific recommendations concerning initiation of therapy. Data on drug response suggest similar response of treatment and similar outcomes in men and women, but female subjects appear to be more susceptible to adverse events related to antiretroviral treatment. Social and behavioural factors may determine gender differences in therapeutic adherence and treatment discontinuation. The available evidence on pharmacokinetics of antiretroviral drugs suggests higher exposure in women compared to men. The factors and mechanisms more likely to be clinically relevant in determining this difference are represented by body weight and composition, renal clearance, and P-glycoprotein activity. Many antiretroviral drugs influence P450 activity, and interactions are common. The results of the studies exploring gender differences in ...Continue Reading

Allergy and Asthma
Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
Birth Defects
Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
Cellular Immunometabolism
Immunometabolism involves not only the way metabolites are digested by the immune system, but the way in which they can alter the pathway of the immune system. These responses occur in day-to-day healthy cell functioning, but can result in diseases, such as autoimmune disorders. Discover the latest research on cellular immunometabolism here.
