Abstract

Purpose

Haemorrhagic cystitis (HC) after allogeneic transplantation (HSCT) is a condition characterized by diffuse inflammation and bleeding from the bladder mucosa. Treatment of HC is not standardized and clinical Guidelines are elusive. The aim of this study was to evaluate the safety and efficacy of intravesical treatment with platelet-rich plasma (PRP) in patients with HC after allogenic HSCT.

Methods

Data from ten consecutive patients with BK virus-induced HC between 2013 and 2017 were collected. HC was classified into four grades. Inclusion criteria were (a) grade 3 or 4 BKV-induced HC after allogenic HSCT; (b) HC refractory to conservative therapy. All patients underwent transurethral cystoscopy and PRP treatment under general anaesthesia.

Results

Mean patients’ age was 33.6 years. Four patients (40%) presented a grade 3 BKV-induced HC and six patients (60%) a grade 4. No intraoperative complications occurred. Postoperative complications were recorded in six patients: three patients required blood transfusion while three patients endovenous antibiotic therapy. Median time to catheter removal was 6 days (IQR 2–10). Median length of hospitalization was 35 days (IQR 6–73). At 30 days after surgery, a three-way catheter was repositioned in one patient for grade 4 haematuria, six patients had a complete response, and three a partial response.

Conclusions

Our preliminary experience suggests that intravesical administration of PRP should be considered as a feasible and safe option for the treatment of BK-induced HC after HSCT. Future studies are needed to assess its potential value in other forms of haemorrhagic cystitis.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
