SCREENING FOR URINARY-TRACT INFECTION IN CHILDREN WITH CANCER

Neutropaenia and immunosuppression place children on treatment for mal ignancies at a high risk for infections, We undertook to determine the prevalence of urinary tract infection (UTI) in children on treatment for cancer at the Kenyatta National Teaching and Referral hospital, Wi th the understanding that many laboratories in the rural areas of the country lack appropriate facilities for confirmation of UTI, it was al so important to evaluate simple and inexpensive screening methods agai nst a ''gold standard'' in this cross sectional study. One hundred and eighty six children between the ages of five and 14 years admitted in Kenyatta hospital with leukaemia or lymphoma were enrolled. Besides c linical evaluation, urinalysis and culture and sensitivity were perfor med on all the subjects. Urine culture was considered the ''gold stand ard'' for diagnosis for UTI, The prevalence of UTI was 8.1% (CI=6.1, 1 0.1), Only five out of 15 patients were symptomatic. E. coli and klebs iella spp, were responsible for 93.4 % of the infections, Presence of pyuria, defined as five or more pus cells per high powerfield, had a s ensitivity of 80.0 %,specificity of 97.1% and a positive predictive va lue of 70.6% while comparative values associated with a positive nitri te test were 60%, 97.7% and 96%, Of her clinical and laboratory tests had low sensitivity. UTI is a relatively frequent infection in childre n on cancer treatment, Screening for pyuria is simple, inexpensive and an accurate method of diagnosing UTI in children on treatment for lym phohaematopoietic malignancies in situations where facilities for urin e culture are unavailable.
