It is quite obvious that African paediatricians are facing numerous challenges. However, their daily fight against frequent pathologies such as malaria, diarrhoeal diseases and respiratory infections should not prevent them from taking into consideration the existence of other pathologies, particularly urinary infections. The clinical picture of urinary infections which is often polymorphic would require a systematic test among infants. Reactive fillets may therefore be relevant in detecting such urinary infections. This survey shows that the best intrinsic values of the fillets used (multistix® 8 SG) are reached with leucocytes (sensibility: 95%) and with the combination of leucocytes and nitrites (specificity: 77.1%). The best predictable validities were obtained with the combination of leucocytes and nitrites (positive predictable value: 68.1%) as well as with the combination of leucocytes or nitrites (negative predictable value: 86%). In the daily practice, reactive fillets may turn out to be helpful to the clinician. The negativity of both tests speaks for the isolation and exclusion of urinary infections. On the other hand, the positivity of both tests highlights a strong urinary infection which is subject to a careful and rigorous use of fillets.
