Contrast Nephropathy Associated FFA

Status Active, not recruiting

Clinical Trial Summary

After the use of iodinated contrast agents, there is a risk of developing contrast nephropathy. Limited data in the literature are available on the incidence of contrast nephropathy after fluorescein angiography (FFA), which is an iodine-free organic contrast. Additionally, factors associated with contrast nephropathy after FFA are not clearly understood. Our study aims to evaluate these points.

Clinical Trial Description

It is known that patients are at risk of developing contrast nephropathy after FFA with iodinated contrast media. However, although it is known that contrast nephropathy may develop after FFA with fluorescein, a non-iodinated organic contrast agent, there is very limited data in the literature. In this study, we aimed to determine the incidence of contrast nephropathy after FFA for retinopathy evaluation and to evaluate the associated factors (age, gender, diabetes mellitus, hypertension, chronic kidney disease, baseline renal function, medications, etc.). Our study was planned prospectively. Patients over the age of 18 years who applied to Prof. Dr. Cemil Taşcıoğlu City Hospital Eye Clinic as outpatients and who did not meet the exclusion criteria and agreed to participate in the study will be included in our study. Age, gender, demographic, clinical and laboratory data of these patients will be recorded from the patient file and hospital data processing system. The definition of contrast nephropathy is defined as an increase in serum creatinine (SCr) ≥0.5 mg/dL or more than 25% of the baseline value in the study titled "Contrast-induced Kidney Injury:Focus on Modifiable Risk Factorsand Prophylactic Strategies", "Risk of nephropathy after intravenous administration of contrast material: a critical literature analysis. In this study, an increase of 0.3 mg/dL in serum creatinine within 48 hours after contrast was accepted. The definition of contrast nephropathy will be evaluated separately as both an increase of 0.5 mg/dl or 25% increase in creatinine value compared to baseline and an increase of 0.3 mg/dl compared to baseline. In this way, there are studies in which the frequency of contrast nephropathy was evaluated separately according to both criteria in the same study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
