Antibiotics can up kidney stone risk: Study

ISLAMABAD
People treated with certain oral antibiotics have a heightened risk of developing kidney stones, new study has found.
This is the first time that these medicines have been linked to this condition. The strongest risks appeared at younger ages and among patients most recently exposed to antibiotics.
“The overall prevalence of kidney stones has risen by 70 percent over the past 30 years, with particularly sharp increases among adolescents and young women,” said study leader Gregory E. Tasian, of Children’s Hospital of Philadelphia (CHOP) USA.
Tasian noted that kidney stones were previously rare in children.
The study team drew on electronic health records from the United Kingdom, covering 13 million adults and children seen by general practitioners in the Health Improvement Network between 1994 and 2015. The team analyzed prior antibiotic exposure for nearly 26,000 patients with kidney stones, compared to nearly 260,000 control subjects, Medical Daily reported.
They found that five classes of oral antibiotics were associated with a diagnosis of kidney stone disease. The five classes were oral sulfas, cephalosporins, fluoroquinolones, nitrofurantoin, and broad-spectrum penicillins.
After adjustments for age, sex, race, urinary tract infection, other medications and other medical conditions, patients who received sulfa drugs were more than twice as likely as those not exposed to antibiotics to have kidney stones; for broad-spectrum penicillins, the increased risk was 27 percent higher.
The strongest risks for kidney stones were in children and adolescents. The risk of kidney stones decreased over time but remained elevated several years after antibiotic use.
Tasian pointed out that other researchers have found that roughly 30 percent of antibiotics prescribed in office visits are inappropriate, and children receive more antibiotics than any other age group, so the new findings reinforce the need for clinicians to be careful in prescribing correct antibiotics.
