title: [Pneumococcal conjugate vaccine failure in HIV-infected child. Clinical case].
abstract: Despite appropriate antimicrobial therapy and vaccination, invasive pneumococcal infections remain associated with significant mortality, especially in selected high-risk groups (asplenic, humoral immunity deficient patients, etc.). We present a 13-year-old caucasian boy with HIV infection (vertical transmission). He received treatment with highly-active antiretroviral therapy (amprenavir, lamivudine and zidovudine) and vaccination with 23-valent vaccine (6 years old) and 7-valent pneumococcal conjugate vaccine (10 years old). His CD4 count and his viral load at these times were 2,063/microl and 13461 cop/ml, when he was 6 years old and 1,315/microl and 32400 cop/ml when he was 10 years old, respectively. The latest CD4 count (1,000/microl) and his viral load (3800 cop/ml) confirmed satisfactory control of the disease. He was referred to our emergency department presenting with fever, head and stomach-ache and vomiting. In the following hours his condition continued to deteriorate and depressed level of consciousness and meningismus were observed. Streptococcus pneumoniae, serotype 18 C, was detected in blood and cerebrospinal fluid cultures. Despite appropriate treatment with antibiotics (cefotaxime and vancomycin) and anti-oedema medications, brain-death was confirmed 24 hours after his admittance.
