Effect of intravenous calcium administration on gentamicin-induced nephrotoxicosis in ponies.
Abstract: To determine whether supplemental i.v. calcium administration would attenuate or prevent gentamicin-induced acute renal failure, defined as an increase in serum creatinine concentration > or = 50% above baseline. Methods: 10 healthy pony mares. Methods: Pony mares were randomly assigned to receive calcium at a dosage of 20 mg/kg of body weight or saline solution i.v., twice daily for 14 days. All pony mares received gentamicin at a dosage of 20 mg/kg i.v. every 8 hours for 14 days. Gentamicin pharmacokinetic, serum biochemical, and urinalysis data were measured every other day for the 14-day study period. Renal histologic examination was performed, and results were scored at the end of the 14-day period. Results: 4 of 5 mares not receiving calcium supplementation developed acute renal failure. Only 1 of the 5 mares receiving calcium supplementation developed acute renal failure. Over the course of the study, pony mares receiving calcium supplementation had significantly fewer changes in urinalysis variables, and significantly less microscopic renal damage. Conclusions: Daily i.v. administration of calcium attenuated gentamicin-induced acute renal failure. Conclusions: Calcium supplementation may help diminish the risk of acute renal failure associated with aminoglycoside antibiotics.

This research explores the impact of intravenously administered calcium on the harmful effects gentamicin – a particular type of antibiotic – has on the kidneys of ponies. The results suggest that calcium can substantially lessen kidney damage caused by gentamicin.
Research Methodology
- The study was conducted on 10 healthy pony mares, split randomly into two groups.
- One group was given calcium intravenously at a dosage of 20 mg per kilogram of body weight, twice a day, over a span of two weeks.
- The control group received a saline solution under the same conditions.
- All ponies were given gentamicin (an antibiotic) at a dosage of 20 mg per kilogram intravenously every eight hours for the same period.
- The effects of gentamicin and calcium/saline solution on the ponies were closely monitored over the course of the study. This was done through regular measurements of gentamicin pharmacokinetic, serum biochemical, and urinalysis data every other day.
- At the end of the two weeks, the ponies’ kidneys were examined histologically, and the results were scored.
Research Findings
- Four out of five ponies that did not receive calcium developed acute renal failure.
- In contrast, only one out of five ponies that received the calcium supplement developed acute renal failure.
- Therefore, the research found that ponies who were given the calcium supplement demonstrated significantly fewer changes in urinalysis variables, indicating that calcium helped reduce the overall impact on their kidneys.
- Furthermore, these ponies had significantly less microscopic renal damage compared to the control group.
Conclusions
- This daily intravenous administration of calcium significantly lessened the severity of gentamicin-induced acute renal failure in ponies.
- Consequently, the study concludes that calcium supplementation can assist in reducing the risk of acute renal failure associated with antibiotics of the aminoglycoside class, such as gentamicin.
