Introduction: The most common adverse effects associated with bisphosphonates are renal toxicity, acute-phase reactions, gastrointestinal toxicity, osteonecrosis of the jaw, transitory fever and uveitis. We report a unique adverse case of vasculitis induced by clodronate.
Case Presentation: A 61-year-old Caucasian woman developed bilateral renal ischemia after kyphoplasty and clodronate treatment for lumbar vertebral fracture. Tests revealed a vasculitis due to clodronate treatment. The antithrombotic and immunosuppressive drugs allowed us to reduce the extent of the renal ischemia. In the following months the increased auto-antibodies returned to the healthy physiological range, but the chronic renal failure persisted.
Conclusions: Drug-induced vasculitis is an inflammation of blood vessels caused by the use of various pharmaceutical agents. The spectrum of drug-induced vasculitis can range from cutaneous rashes to fatal multi-organ involvement. To the best of our knowledge this is the first documented case of drug-induced vasculitis caused by clodronate in the literature. Previously, it was verified that clodronate injection could increase the pro-apoptotic action on immune cells. Further studies are necessary to clarify the role of bisphosphonates on drug-inducing vasculitis.

The role of mitochondrial reactive oxygen species in initiating mitochondrial damage and inflammation in wasp-venom-induced acute kidney injury.

Acute kidney injury induced by stings from multiple wasps is a medical emergency and is a driving factor of acute renal dysfunction. Numerous studies have shown that mitochondrial reactive oxygen species (mtROS) play a key role in ischemia-reperfusion injury-, cisplatin-, and sepsis-induced acute kidney injury. However, the role of mtROS and its underlying mechanisms in wasp-venom-induced acute kidney injury remain inconclusive.

Sevelamer is a non-absorbable polymer used to treat hyperphosphatemia in individuals with end-stage renal disease (ESRD) undergoing hemodialysis. The deposition of sevelamer crystals in the gastrointestinal (GI) tract, especially in the colon, can cause mucosal inflammation, pseudopolyps, ulceration, ischemia, or necrosis. Owing to its rarity and lack of physician awareness, the actual incidence and prevalence of sevelamer-induced gastrointestinal mucosal injury (SIGMI) remain unknown.

Background: Over the last decade, the number of simultaneous heart-kidney transplants (SHKTs) has increased dramatically. There are few reports of renal allograft outcomes in these high acuity patients. The goal of the present study was to identify variables that were related to early adverse outcomes (EAOs), including delayed graft function (DGF), primary non-function (PNF), and renal allograft futility (RAF) after SHKTs.

Background: Renal ischemia-reperfusion injury (RIRI) stands as an unavoidable complication arising from kidney surgery, profoundly intertwined with its prognosis. The role of differentially expressed in FDCP 6 homolog (DEF6) in RIRI remains elusive, despite its confirmation as a potential therapeutic target for diverse diseases. Here, we investigated the mechanism by which DEF6 regulated RIRI.

Objective: This study investigates the effects of caloric restriction (CR) on renal injury and fibrosis following ischemia-reperfusion injury (IRI), with a focus on the roles of the mechanistic/mammalian target of rapamycin complex 1 (mTORC1) signaling and autophagy.
Methods: A mouse model of unilateral IRI with or without CR was used. Renal function was assessed through serum creatinine and blood urea nitrogen levels, while histological analysis and molecular assays evaluated tubular injury, fibrosis, mTORC1 signaling, and autophagy activation.
