Have received conjugate pneumococcal vaccination against Hib and S. pneumoniae (otherwise eligible but unvaccinated children will be vaccinated through the study as above) ? Carer willing/able to provide consent and to bring the child for follow-up visits, as demonstrated by either regular attendance at SCD clinics to date, or attending two visits (one of which may be the screening visit) before randomisation
Exclusion criteria
Exclusion criteria: ? Weighing 5/year), known abnormal transcranial Doppler ultrasound velocities, stroke or acute chest syndrome) ? Already receiving hydroxyurea ? Taking concomitant medications that are contraindicated with any of the trial medications (hydroxyurea, SP, DHA-PQP, penicillin V, cotrimoxazole) (including, but not limited to, nefazodone, verapamil, rifampicin, isoniazid, ethambutol) ? A positive pregnancy test at screening or enrolment visits ? Known cancer ? A clinical history of previous or existing liver or renal diseases unrelated to sickle cell disease ? Known cardiac ventricular dysfunction or failure or a previous history of cardiac arrhythmias ? Known HIV (these children should receive cotrimoxazole prophylaxis and many will be receiving antiretrovirals that are contraindicated with one or more trial medications (zidovudine, amprenavir, atazanavir, indinavir, nelfinavir, ritonavir)) ? Current participation in any other clinical trial of an investigational medicinal product ?
