[Associated risk factors for serious bacterial illness in children less than 24 months, admitted with fever without source].
OBJECTIVE
To analyze risk factors for serious bacterial illness (SBI) in children less than 2 years of age admitted with fever without source.


METHODS
Children under 2 years admitted at the Pediatric Service of Sanatorio Mater Dei from May 2004 to December 2005.


METHODS
Observational, prospective and longitudinal study.


METHODS



METHODS
age, gender, siblings, household viral infections, day care attendance, vaccination, season, laboratory data, Rochester criteria, YIOS scale, antibacterial treatment, length of hospitalization, and final diagnosis. A multiple logistic regression stepwise model was used.


RESULTS
70 out of 201 patients developed SBI, 56 were under 3 months of age. Predominant diagnosis were: urinary tract infection (n: 47), meningitis (n: 11) and bacteremia (n: 9). Predictive factors: white-cells count > 15.000/mm3 (coef 1.05, OR = 2.17, 95% CI 1.13-4.15) and household viral contact (coef-0.79, OR 0.42, CI 0.23-0.77).


CONCLUSIONS
Risk factor for SBI was leucocytes count >15.000/mm3. Household viral contact proved being a protective factor.
