HIV-Associated Growth Failure: Serostim
This study will determine the effect of Serostim on children's growth (height and weight), and determine if growth hormone has any effect on the ability to gain and maintain lean body mass (muscle). Since growth hormone has not been tested in HIV-infected children before, this study will also determine the safety of using Serostim in this population. During the screening process, children will have an MRI (magnetic body scan) to determine fat and muscle content, a body water measurement (using a saliva test), and a BIA test. Participating children will be assigned by chance to one of four groups. Children in Group 1 will receive one dose of growth hormone once a day for 96 weeks. Children in Group 2 will receive half the dose given to Group 1 once a day for 96 weeks. Children in Groups 3a and 3b will receive no Serostim for the first 24 weeks of the study. After 24 weeks, they will receive either a full dose once a day (Group 3a) or half the full dose (Group 3b) once a day for
the remaining 72 weeks of the 96-week study. Serostim will be given by the child's parent or guardian once a day at bedtime by injection under the skin. Parents/guardians will be taught how to give injections at home and dispose of needles safely. There is no CD4 cell count requirement but subjects must have fewer than 20,000 copies/mL of HIV RNA or a documented viral load decrease of at least 1 log10 from baseline viral load while on antiretroviral therapy. Girls must be between 4 and 12 years of age; boys, between 4 and 13 years of age. Participants must have documented height growth failure and a dietary intake of at least 100% of the recommended dietary allowances for calories and protein. Persistent fevers, serious infections, retractable diarrhea, cancers, and diabetes are not allowed. The study is being conducted in Long Island (718-470-3300), Los Angeles (310-206-6369), Newark (973-972-3118), San Diego (619-543-8080 ext. 204), and San Francisco (415-476-6480).
Antiretroviral Therapy and Body Composition
This study will determine if any changes occur in children's body weight, growth, body fat, muscle mass or fat, and muscle distribution after starting or changing anti-HIV medications. This is an observational study. After screening, there will be four study visits at weeks 12, 24, 36, and 48. During these visits, participating children will undergo physical exams, blood tests, and body measurements such as weight, height, arm size, and leg size. The distribution of fat and muscle will be measured using calipers to determine the thickness of the child's or baby's skin. Subjects will also undergo a BIA, which measures body fat as well as lean body mass; the BIA tests are quick and painless. Children and their parents will also answer questions about the types of food eaten on certain days. The study will last 48 weeks. Children must be between one month and 13 years of age and beginning or changing antiretroviral therapy. Acute illnesses, cancers, metal prostheses or
implanted electrical devices, previous limb amputation, and diabetes requiring insulin are not allowed. Study sites include Newark (973-972-3118), Oakland (510-428-3885 ext. 2827), and San Francisco (415-476-6480). (ACTG P1010)
