Cystatin c: a Biomarker of AKI in Aneurysmal Subarachnoid Haemorrhage Patients

Completed

• Conditions: Acute Kidney Injury

• Registration Number: NCT06635408
• Lead Sponsor: Alexandria University

Brief Summary

The goal of this observational study is to assess cystatin c as a predictive biomarker of early acute kidney injury in aneurysmal subarachnoid hemorrhage patients. The main question it aims to answer is:

- Does cystatin c biomarker can predict early acute kidney injury in aneurysmal subarachnoid hemorrhage patients?

Participants will be grouped into Aki and Non-Aki groups based on RIFLE criteria and Cystatin c biomarker will be tested to answer the study question.
