New York: Antibiotic use following surgery for complicated appendicitis may do more harm than good, suggests new research.

The researchers found that patients who received antibiotics following complicated appendicitis surgery remained in the hospital up to one day longer than similar patients who had not received antibiotics.

“Our study indicates antibiotics may not be necessary following surgery for complicated appendicitis,” said lead researcher Dennis Kim from Los Angeles Biomedical Research Institute in the US.

The researchers studied the outcomes over five years for 410 adults with complicated appendectomies, or those where the appendix was found to be perforated or gangrenous.

Post-operative antibiotics were administered to 274 of those patients, or 66.8 percent.

The study compared patients who received post-operative antibiotics to those who had not received the medications and found no significant difference in wound complications among the two groups.

The 274 patients who received post-operative antibiotics did have slightly longer hospital stays – an average of about one day longer – than the patients who did not receive the medication.

“Antibiotics are not without risks, costs or complications. While further study is needed, surgeons and physicians may wish to re-examine or be more selective in deciding which patients may potentially benefit from post-operative antibiotic therapy for complicated appendicitis,” Kim noted.

The study was published online in the American Journal of Surgery.

Oral Antibiotics Possess Threat of Kidney Stones

For broad-spectrum penicillins, the increased risk was 27 per cent higher, the researchers added.

Children and adults treated with oral antibiotics may have a higher risk of developing kidney stones, according to a new study.

The findings, published in Journal of the American Society of Nephrology, suggested that 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 per cent over the past 30 years, with particularly sharp increases among adolescents and young women,” said lead author Gregory E. Tasian from the Children’s Hospital of Philadelphia (CHOP).

According to the researchers, kidney stones were previously rare in children.

“The reasons for the increase are unknown, but our findings suggest that oral antibiotics play a role, especially given that children are prescribed antibiotics at higher rates than adults,” said co-author Michelle Denburg from CHOP.

For the study, the team analysed prior antibiotic exposure for nearly 26,000 patients with kidney stones, compared to nearly 260,000 control subjects.

They found that five classes of oral antibiotics — oral sulfas, cephalosporins, fluoroquinolones, nitrofurantoin, and broad-spectrum penicillins — were associated with a diagnosis of kidney stone disease.

After adjustments for age, sex, race, urinary tract infection, other medications and medical conditions, patients who received sulfa drugs were more than twice as likely as those not exposed to antibiotics to have kidney stones, the researchers said.

They also mentioned that the risk of kidney stones decreased over time but remained elevated several years after antibiotic use.

“Our findings suggest that antibiotic prescription practices represent a modifiable risk factor, a change in prescribing patterns might decrease the current epidemic of kidney stones in children,” Tasian noted. (IANS)
