Nonadherence with pediatric human immunodeficiency virus therapy as medical neglect.

OBJECTIVE: To examine the results of an interventionist approach applied to human immunodeficiency virus (HIV)-infected children for whom caregiver nonadherence was suspected as the cause of treatment failure. METHODS: The medical records of a cohort of 16 perinatally HIV-infected children whose care was managed at the Arkansas Children's Hospital Pediatric HIV Clinic for an uninterrupted period of >or=3 years were reviewed through July 2003. Data collected included date of birth, dates of and explanations for clinic visits and hospitalizations, dates of laboratory evaluations, CD4(+) T cell percentages, plasma HIV-1 RNA levels, antiretroviral medications, viral resistance tests (eg, phenotype and genotype), and physician-initiated interventions to enhance adherence to the medication regimen. A stepwise interventionist approach was undertaken when patients continued to demonstrate high viral loads, despite documented viral sensitivity to the medication regimen and caregivers' insistence that medications were being administered regularly. Step 1 was prescribing a home health nurse referral, step 2 was administering directly observed therapy (DOT) while the patient was hospitalized for 4 days, and step 3 was submitting a physician-initiated medical neglect report to the Arkansas Department of Human Services. RESULTS: The results for 6 patients for whom this stepwise approach was initiated are reported. Home health nurse referrals failed to result in sustained improvements in adherence in all 6 cases. Viral load assays performed before and after DOT provided an objective measure of the effect of adherence, with 12 hospitalizations resulting in a mean +/- SD decrease in HIV RNA levels of 1.09 +/- 0.5 log(10) copies per mL, with a range of 0.6 to 2.1 log(10) copies per mL. Four families responded to DOT hospitalization, and sustained decreases in the respective patients' viral loads were noted. In 2 cases, medical neglect reports were submitted when DOT did not result in improved adherence. These patients were eventually placed in foster care, with subsequent improvements in their viral loads and CD4(+) T cell percentages. CONCLUSIONS: Nonadherence with antiretroviral therapy can be established on the basis of persistently elevated HIV RNA levels that decrease with DOT. Nonadherence poses a danger to the child that is grave and potentially irreversible. Caregivers should be offered all available resources to help them adhere to a sound treatment plan. In cases of demonstrated inability to provide needed care, it is necessary to consider seeking child protection, even for apparently healthy children.

Impact of the conjugate pneumococcal vaccine in arkansas.

BACKGROUND: On the basis of the success of the early trials in the prevention of invasive pneumococcal disease in infants and children using a heptavalent conjugate pneumococcal vaccine, the American Academy of Pediatrics recommended in August 2000 that the vaccine be given concurrently with other childhood immunizations. METHODS: Data concerning invasive pneumococcal infections from 1998-2000 were compared with 2001-2003 to assess the impact of the heptavalent pneumococcal conjugate vaccine in Arkansas. Basic demographic data were gathered as well as history of vaccination with the pneumococcal vaccine, underlying medical conditions, site of infection and morbidity and mortality. Pneumococcal isolates were serogrouped or serotyped and penicillin susceptibilities were obtained. RESULTS: The incidence of invasive disease decreased from a high of 5.78/100,000 population to 3.02/100,000 population (P = 0.002). Although the percentage of White patients increased from 2001-2003, the overall incidence of disease did not change. The incidence of disease among Blacks fell from 20.5/100,000 population to 4.9/100,000 population. The greatest decrease of disease occurred in children 24 months of age or younger with the incidence rate falling from 44.2/100,00 population to 8.30/100,000 population (P < 0.02). The incidence among White children 24 months of age or younger fell from 19/100,000 population to 1.8/100,000 population, whereas that of Black children 24 months of age or younger declined from 164/100,000 to 35/100,000. From 1998 to 2000, 3.7/100 cases were from nonvaccine serogroups compared with 44/100 cases from 2001 to 2003 (P < 0.001). In children 24 months of age or younger, the number of nonvaccine isolates increased from 1.3/100 cases to 30.5/100 cases (P < 0.001). Overall 56 (44%) were nonsusceptible to penicillin from 1998 to 2000; that was not significantly different from 2001-2003 when 37 (46%) of 81 isolates were nonsusceptible to penicillin. CONCLUSIONS: A significant decrease of invasive pneumococcal disease has been documented in Arkansas. Of concern, however, is the increasing number of invasive isolates not included in the current vaccine.
