Objective: This study was performed to determine the relationship between urinary nitrite results and
bacterial resistance to antimicrobial drugs in urinary tract infection of children.
Methods: In a cross-section study 119 children younger than 12 years with urinary tract infection were
evaluated in Qazvin children's hospital. Patients were divided into negative and positive nitrite groups
depending on urinary nitrite test result. Rates of antibiotic resistance in the two groups were compared.
Findings: Sixty seven patients were in the negative nitrite group and 52 in the positive nitrite group.
Resistance rates to ceftriaxone, trimethoprim sulfamethoxazole, ampicillin, gentamicin, amikacin, nalidixic
acid, cephalothin and nitrofurantoin in the nitrite negative group were 7.5%, 31.3%, 50.7%, 11.9%, 9%, 3%,
14.9% and 11.9%, respectively. These values in the nitrite positive group were 21.2%, 28.8%, 63.5%, 7.7%,
5.8%, 1.9%, 9.6%, and 3.8%, respectively (P >0.05).
Conclusion: This study showed that there is no correlation between urinary nitrite results and bacterial
resistance to antimicrobial drugs. Therefore, it seems that physicians should not adjust antibiotic therapy for
UTI based on nitrite results.
