Adherence to high activity antiretrovial therapy (HAART) in pediatric patients infected with HIV: issues and interventions.

It has been proven that HAART is effective in suppressing human immunodeficiency virus (HIV) replication, decreasing morbidity and mortality associated with HIV and improving quality of life in adults as well as children infected with HIV. However, drugs don't work in patients who don't take them and in the management of HIV infection it is now well established that optimum adherence to HAART is critical to successful outcome of patients receiving therapy. At least 95% adherence to HAART is optimum and studies have shown that 50%. Important factors that influence adherence to HAART such as regimen related complexities, patient/family related issues and factors related to healthcare delivery system makes adherence to HAART challenging. Although numerous interventions to improve adherence have been investigated in developed as well as developing countries, majority of work in this area is focused on adherence in adults and data in children is limited. Therefore, in order to facilitate adherence and improve outcome of HAART in pediatric population, it is necessary to have a deep understanding of the factors influencing adherence and interventions that can improve adherence in children.
