TUESDAY, June 4 (HealthDay News) -- Some women with symptoms of a urinary tract infection may be able to skip the antibiotics typically prescribed and have their symptoms improve or clear, according to a new Dutch study.
"In healthy people, many mild infections can be cured spontaneously," said study leader Dr. Bart Knottnerus, a researcher at the Academic Medical Center of the University of Amsterdam.
A U.S. expert, however, had a number of cautions about the findings, including the small number of women studied.
For the research, published May 31 in the journal BMC Family Practice, Knottnerus recruited women from 20 general medical practices in and around the Netherlands from 2006 to 2008. Women who had contacted their doctor complaining of frequent urination, painful urination or both were asked if they would be willing to delay antibiotics -- but only if their symptoms had been present for no longer than seven days.
Certain women were excluded, including those pregnant or breast-feeding or those whose immune systems were compromised.
In all, 176 women participated. Of those, 137 were asked to delay antibiotics and 51 agreed. All the women gave a urine sample to be analyzed and cultured. The women reported on their symptoms over the next week.
After a week, 28 of the 51 women willing to delay antibiotic use still had not used an antibiotic. Twenty of these women (71 percent) reported disappearance or improvement of their symptoms. Of these 20, more than a third had a positive culture result, indicating an infection. The researchers did not know the culture results at the start of the study.
Most of the women not willing to delay antibiotics had a positive culture.
The women who did agree to delay, Knottnerus said, might be aware of the bacterial resistance that can result from antibiotic use. "Furthermore," he said, "in the Netherlands
