NCT02476526

Brief Summary

The purpose of this study is to show that the use of low volume iso-osmolar non-ionic radio contrast medium (30 cc) in a thoracic CT Scanning procedure in a selected group of patients with chronic kidney disease (CKD) will avoid contrast induced nephropathy (CIN) in comparison to a similar group of patients with CKD who receive no contrast medium..

Conditions

Outcome Measures

Primary Outcomes (1)

  • Peak Serum Creatinine Level

    The peak serum creatinine increase over baseline within 72 hours after intervention is the outcome variable. This variable is used for comparison between two groups, as well as for safety monitoring in the intervention group (25% increase is the upper threshold)

    Up to 72 hours after intervention

Study Arms (2)

Low Volume Contrast

EXPERIMENTAL

Subjects in this arm will receive a single intravenous injection of low volume iso-osmolar non-ionic radio contrast medium, prior to undergoing 64-MDCT scanning. The use of low volume radio contrast medium constitutes the intervention. Both experimental and control groups receive a) acetylcysteine inhalation (Mucomyst) 1200 mg po BID x 48 hours starting the day prior to the CT scan; and b) isotonic Sodium Bicarbonate Solution 3ml/kg/hr iv for 1 hour prior to the CT scan and for 6 hours after the CT scan

Drug: Low Volume iso-osmolar non-ionic radio contrast mediumDrug: Acetylcysteine InhalationDrug: Sodium Bicarbonate SolutionProcedure: 64-MDCT Scanning

Control

SHAM COMPARATOR

Subjects in this arm will undergo 64-MDCT scanning without Radio Contrast Medium (RCM). Both experimental and control groups receive a) acetylcysteine inhalation (Mucomyst) 1200 mg po BID x 48 hours starting the day prior to the CT scan; and b) isotonic Sodium Bicarbonate Solution 3ml/kg/hr iv for 1 hour prior to the CT scan and for 6 hours after the CT scan

Drug: Acetylcysteine InhalationDrug: Sodium Bicarbonate SolutionProcedure: 64-MDCT Scanning

Interventions

Intravenous injection of low volume (30 cc) iso-osmolar non-ionic radio contrast medium as part of the 64-MDCT Scanning procedure (intervention group only)

Also known as: Visipaque 320

Both experimental and control groups will undergo 64-MDCT scanning over the thoracic area

Also known as: 64-Multi-Detector Computed Tomography Scanning

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects with documented stable Chronic Kidney Disease (CKD) defined as a stable eGFR 16-60 ml/min/m\^2 for ≥ 12 months; and
  • Referred to CT scanning procedure to evaluate pulmonary embolism, pulmonary malignancy, acute aortic syndromes, or renal artery stenosis.

You may not qualify if:

  • CKD Stages 1, 2 and 5
  • Stage 3-4 congestive heart failure (CHF)
  • Irregular supraventricular tachycardia
  • Allergic to iodinated Radio Contrast Medium (RCM)
  • Allergic to Mucomyst
  • Pregnancy
  • Evidence of acute renal failure (ARF)
  • Serum bicarbonate either less than 20 meq/L or greater than 35 meq/L
  • Hydration with a bicarbonate solution is contraindicated or considered unsafe by the subject's caring physicians
