There are many controversies about the role of N-Acetyl Cystein in preventing of contrast nephropathy. These contradictory results may be due to different criteria for patients' selection, different end points, different type and dose of N-Acetyl Cystein administration and finally different prophylactic measures other than N-Acetyl Cystein. The investigators try to enroll a double blind double dummy study with a good power to compare the effect of this drug both in the form of oral and intravenous against the placebo in preventing the contrast nephropathy in the patients whom undergo coronary angiography/angioplasty.

Further study details as provided by Imam Khomeini Hospital:

Primary Outcome Measures:
  • Increase in serum creatinine more than 25% of baseline [ Time Frame: 24 hours, 48 hours after exposure to contrast media ]

Secondary Outcome Measures:
  • Increase in serum creatinine more than 25% of baseline [ Time Frame: The 5th day after exposure to contrast media ]

Estimated Enrollment: 549
Study Start Date: March 2013
Estimated Study Completion Date: November 2014
Estimated Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Intravenous N Acetyl Cystein
1200 mg IV N- Acetyl Cystein half an hour before contrast administration. This group will also take oral placebo
Drug: IV N-Acetyl Cystein
Bolus IV administration of 1200 mg N- Acetyl Cystein half an hour before contrast media administration
Placebo Comparator: Placebo
Patients on both oral placebo and IV placebo just like patients on oral and IV N-acetyl cystein groups in regard of dose and timing.
Drug: Placebo group
The patients in this group will be received both oral placebo and IV placebo
Active Comparator: Oral N Acetyl Cystein
Patients on 600 mg oral N-Acetyl Cystein bid started at the day before contrast exposure and continue until the next day of contrast exposure.These patients will also take IV placebo
Drug: Oral N-Acetyl Cystein
Oral N-Acetyl Cystein 600 mg bid started the day before contrast administration and continue the day after exposure to contrast

Detailed Description:
Contrast Nephropathy is the third cause of acute kidney injury in hospitalized patients. The morbidity and mortality of this disorder is considerable. There is no treatment for this condition and all measures should be taken into account to prevent this complication. Among the all prophylactic measures hydration and the dose ant type of contrast are the only factors that have been proved to be effective in preventing contrast nephropathy. N-Acetyl Cystein is an antioxidant agents that may be effective in different aspects of medicine, but it,s use in this condition is controversial. While some studies showed it is effective in prevention of contrast nephropathy, others showed no benefit. Different studies used different dose and route of administration. So more clinical trials with good power are needed to compare different oral Vs IV administration of the drug in a randomized double blinded clinical trial. In this study we allocate the eligible patients with chronic kidney diseases stages 2 to 4 to three groups. Oral N-Acetyl Cystein group, IV N-Acetyl Cystein group, placebo group. All group will be matched according to stages of chronic kidney diseases, diabetes, anemia, heart failure, age and sex.
