From the Guidelines
The patient, Shaniqua, should be treated with ifosfamide as part of her chemotherapy regimen, given that she is already receiving mesna disulfide as a protective agent. Mesna is typically given to prevent hemorrhagic cystitis caused by ifosfamide or cyclophosphamide chemotherapy. According to the most recent and highest quality study, ifosfamide can be administered at a dose of 1200 mg/m² IV on days 1-5, with mesna given at a dose of 120 mg/m² slow IV push before ifosfamide on day 1, then 1200 mg/m² IV continuous infusion on days 1-5 1. The mesna protocol typically involves giving it before chemotherapy and at intervals afterward (usually at 0,4, and 8 hours after chemotherapy) to ensure continuous protection of the bladder. Mesna works by binding to the toxic metabolites of these alkylating agents in the urinary tract, preventing them from damaging the bladder epithelium. Adequate hydration should also be maintained throughout treatment to help flush the bladder and further reduce the risk of hemorrhagic cystitis.
Some key points to consider when administering ifosfamide and mesna include:
- The dose and schedule of ifosfamide and mesna may vary depending on the specific chemotherapy regimen and the patient's individual needs.
- Mesna should be given before and after ifosfamide administration to ensure adequate protection of the bladder.
- Adequate hydration is essential to help flush the bladder and reduce the risk of hemorrhagic cystitis.
- The patient should be closely monitored for signs and symptoms of hemorrhagic cystitis, such as hematuria, dysuria, and pelvic pain.
It's worth noting that the use of mesna with ifosfamide has been well established in the literature, with studies demonstrating its effectiveness in preventing hemorrhagic cystitis 1. However, the most recent and highest quality study provides the most up-to-date guidance on the use of mesna with ifosfamide 1.

From the Research
Treatment for Hemorrhagic Cystitis
To treat Shaniqua, who is scheduled for chemo and has been given mesna disulfide, the following drugs can be considered:
Efficacy of Mesna
Mesna has been shown to be effective in preventing or diminishing hemorrhagic cystitis induced by ifosfamide 2 and cyclophosphamide 3, 4. However, its efficacy in combination with hyperhydration is still debated 5, 6.
Considerations for Treatment
When considering treatment for Shaniqua, it is essential to take into account the specific chemotherapy regimen she will be undergoing and the potential risks of hemorrhagic cystitis. Mesna has been shown to be a useful uroprotectant in patients receiving oxazaphosphorine chemotherapy 4, but its efficacy may vary depending on the specific context.
