E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the rate of nasal colonization by different pneumococcal serotypes in HIV-positive adults, in relation to baseline antibody titers at T0; to define serological response after 2 doses of PCV13 vaccine (booster dose after 8 weeks) in HIV+ adults; to evaluate the effect of 2 doses PCV13 vaccine in terms of nasal pneumococcal carriage and occurrence of invasive pneumococcal diseases. |
Il progetto si propone di valutare, in modo prospettico, la risposta anticorpale a 2 dosi di PCV-13 e la prevalenza della colonizzazione nasofaringea da S. pneumoniae in una popolazione HIV+ non ospedalizzata, correlando i dati anamnestici, clinici, sierologici e microbiologici; valutare l'effetto di due dosi di PCV13 in termini di colonizzazione nasofaringea e sviluppo di patologia pneumococcica invasiva. |
|
E.2.2 | Secondary objectives of the trial |
To determine pneumococcal serotypes and chemosusceptibility to different antibiotic and to evaluate the prevalence of multiresistant strains; to evaluate molecular epidemiology of pneumococcal isolates. |
La ricerca permettera' di valutare la percentuale di PNSSP, PRSP e/o multiresistenti, ed i sierotipi di pneumococco circolanti in questo tipo di popolazione, in relazione al titolo anticorpale al T0. Con l`analisi dei dati clinici anamnestici ed i successivi follow up, sara` possibile distinguere i soggetti portatori a breve e a lungo termine, stabilirne i fattori di rischio e la frequenza di infezione. Le analisi molecolari permetteranno di definire l`epidemiologia dell`acquisizione, valutando l`eventuale diffusione clonale di alcuni sierotipi di S. pneumoniae e la correlazione genetica fra isolati da portatore e da malattia. |
