Abstract
Purpose: To study bacteriuria in a defined population with special emphasis on asymptomatic infections.
Methods: All newborn infants in the area were offered screening at 2 weeks, 3 and 10 months of age. Bacteriuria was confirmed by bladder puncture. Radiology and tests for level diagnosis were performed. Bacteria were analysed for virulence factors. No treatment was given if the child was asymptomatic and no signs of renal involvement were found.
Results: From Oct 1977 to Dec 1979 2746 2-weeks old infants entered the study (96% participation). So far 2173 have been screened also at 3 months and 1269 at 10 months of age. Bacteriuria was confirmed in 31 boys (2.7%) and 8 girls (0.7%), in all cases without symptoms. Among the boys none had signs of renal involvement, 2 had reflux without dilatation. So far all have spontaneously cleared the bacteriuria before one year of age without any recurrences. One girl had scarred kidneys on IVP and was treated. The other girls became spontaneously free from bacteria within 6 months of diagnosis. 2 had asymptomatic recurrences.
Conclusion: Asymptomatic bacteriuria during infancy was mostly transient. Renal involvement was rare. Screening for bacteriuria among healthy infants does not seem motivated.
