The Safety and Effectiveness of Zidovudine in the Treatment of HIV-Infected Children With Mild to Moderate Symptoms

28 octobre 2021 mis à jour par: National Institute of Allergy and Infectious Diseases (NIAID)

A Multicenter Placebo-Controlled Trial To Evaluate the Safety and Efficacy of Oral Zidovudine in the Treatment of Children Infected With Human Immunodeficiency Virus With Mild to Moderate Symptoms (Including LIP)

To determine the safety and usefulness of zidovudine (AZT) for the treatment of children 3 months to 12 years of age. This study is designed to determine if children who are infected with HIV and who have a special type of lung disease called lymphocytic interstitial pneumonitis (LIP) or other early symptoms of HIV infection may derive benefit from treatment with AZT. It is hoped that this drug will prevent children from developing additional symptoms and infections and will help resolve already existing symptoms.

AZT has been shown in the laboratory to inhibit the infection of cells by HIV. AZT has been shown to decrease the mortality and the frequency of opportunistic infections in certain adult patients with symptomatic HIV infection. It is, therefore, likely that symptomatic HIV-infected children may also benefit from specific antiviral therapy.

Description détaillée

AZT has been shown in the laboratory to inhibit the infection of cells by HIV. AZT has been shown to decrease the mortality and the frequency of opportunistic infections in certain adult patients with symptomatic HIV infection. It is, therefore, likely that symptomatic HIV-infected children may also benefit from specific antiviral therapy.

Children who participate in the study are evaluated at a hospital outpatient clinic and are under the care of a specialist in pediatrics. Of the children who participate in the study, half receive AZT syrup and half receive a placebo (sugar solution). The investigator does not know which medication each child receives as this is decided by a random process. The children take the medication in a strawberry-flavored clear syrup every 6 hours (4 times a day), for a period of 2 years or 104 weeks. The children are monitored on an outpatient basis while receiving therapy and the tests performed on admission to the study are repeated several times during treatment. Blood samples are obtained once a week for the first 4 weeks, every other week for the next 4 weeks, and then monthly until the end of the study. At certain sites, Cerebrospinal fluid (CSF) is collected by lumbar puncture every 52 weeks to evaluate infection involving the brain and nervous system. An independent committee reviews the data collected on the children every 6 months. The drug is stopped or the dose reduced if unacceptable side effects develop. AMENDED: As of August 7, 1989 the study blind was broken, the placebo arm discontinued and the study closed to accrual as of September 25, 1989. The 6 children enrolled in the study have been offered AZT.
