ABSTRACT
Introduction: Few studies have reported on administering enfortumab vedotin to patients with metastatic urothelial carcinoma and end-stage renal disease requiring hemodialysis. Case presentation: Case 1: An 85-year-old man underwent hemodialysis for progressive renal failure 4 months after right laparoscopic radical nephroureterectomy. Case 2: A 73-year-old man underwent hemodialysis after two laparoscopic radical nephroureterectomies for recurrent urothelial carcinoma. In both cases, enfortumab vedotin was administered due to postoperative recurrence and progression despite platinum-based chemotherapy and pembrolizumab. Partial response and disease progression were observed in cases 1 and 2, respectively. Adverse events included a mild skin rash in both patients and neutropenia in Case 1, both of which resolved with symptomatic treatment. Conclusion: The efficacy and safety of enfortumab vedotin in patients with metastatic urothelial carcinoma, and end-stage renal disease undergoing hemodialysis, were confirmed.
ABSTRACT
BACKGROUND/AIM: Overactive bladder (OAB) has recently been recognized as an independent risk factor for falls and fractures. This study aimed to predict fracture risk in female patients with OAB symptoms. PATIENTS AND METHODS: We assessed and compared the fracture risk in newly diagnosed female patients with OAB to those without OAB using the Fracture Risk Assessment Tool (FRAX), and investigated the relationship between fracture risk and OAB severity. RESULTS: The present single-center, cross-sectional study included 177 female participants (79 with OAB, 98 without OAB). The OAB group was older (p=0.033) and shorter (p=0.010) compared to the non-OAB group. Compared to the non-OAB group, the OAB group had more patients with hypertension (p<0.001) and diabetes mellitus (p=0.011), as well as higher risks for major fractures (non-OAB group: 15.2±13.2%; OAB group: 23.6±14.1%; p<0.001) and hip fractures (non-OAB group: 6.3±11.0%; OAB group: 10.6±10.0%; p=0.007). In addition, those with moderate/severe OAB had the most significantly elevated risks for both major fractures (non-OAB group: 15.2±13.2%, mild-OAB: 17.6±12.5%, moderate/sever-OAB: 26.4±14.0%; p<0.001) and hip fractures (non-OAB group: 6.3±11.0%, mild-OAB: 6.5±7.6%, moderate/sever-OAB: 12.5±10.4%; p<0.001). Among the OAB symptoms, nocturia had the strongest correlation with fracture risk (major fracture, ρ=0.534; hip fracture, ρ=0.449; all p<0.001). CONCLUSION: Patients with severe OAB, and particularly severe nocturia, should be closely monitored with timely and aggressive symptom management; however, an interventional study incorporating the management of OAB symptoms is required to confirm whether the proactive management of OAB symptoms reduces the risk of fractures in older females.
