Renal complications from bisphosphonate treatment.

چکیده
PURPOSE OF REVIEW More than 10 years ago evidence emerged that bisphosphonate therapy especially in malignant bone diseases is associated with renal complications. The nature of renal injury from bisphosphonates has become clearer in recent years. RECENT FINDINGS Pamidronate can rarely cause (collapsing) focal segmental glomerular sclerosis with the nephrotic syndrome and renal insufficiency. This renal complication has also been observed with other bisphosphonates but only in isolated cases. Other types of renal injury include transient but self-limited rises in creatinine, and, very rarely, acute tubular necrosis causing acute renal failure. The frequency of the latter two complications appears to follow the potency of different bisphosphonates. Although thus far no tubular transport for bisphosphonates has been identified (renal excretion appears to be only by glomerular ultrafiltration), the occurrence of tubular cell injury gives rise for the possibility that these cells can take up bisphosphonates. In patients receiving bisphosphonates monitoring of serum creatinine before and after intravenous (i.v.) dosing or periodically with oral bisphosphonates is advised. SUMMARY Renal complications with bisphosphonates are rare but creatinine monitoring, especially with i.v. bisphosphonates is strongly advised. The mechanisms by which bisphosphonates can cause renal insufficiency are still elusive and opportunities for research include the discovery of potential mechanisms of tubular cell uptake of bisphosphonates.

Economic Analysis of Bisphosphonate Use after Distal Radius Fracture for Prevention of Hip Fracture
Background: Osteoporosis is a common condition among the elderly population, and is associated with an increased risk of fracture. One of the most common fragility fractures involve the distal radius, and are associated with risk of subsequent fragility fracture. Early treatment with bisphosphonates has been suggested to decrease the population hip fracture burden. However, there have been no p...

Bisphosphonates are important agents for the treatment of skeletalrelated events in cancer therapy, as well as for the treatment of multiple myeloma and osteoporosis. Bisphosphonate-related osteonecrosis of the jaws (BRONJ) is a serious side-effect of bisphosphonate therapy. Its cardinal symptom is exposure of jawbone that does not heal within eight weeks. This condition significantly compromis...
متن کاملBisphosphonate-induced bilateral acute renal cortical necrosis
Renal cortical necrosis (RCN), a rare cause of renal failure in which there is death of the renal cortex but sparing of the medulla, is a catastrophic entity with high mortality. Its incidence and severity are higher in developing countries, mostly due to pregnancy-related complications. This paper presents the case of a 65-year-old woman who had bilateral renal cortical necrosis caused by bisp...
