Description of intervention(s) / exposure
Treatment: Drugs - N-acetylcysteine
Experimental: 1 - 5 patients: 28 days of n-acetylcysteine (in addition to standard therapy) and then repeat serum creatinine and vascular study then crossover to placebo for 28 days after one week washout period.
Placebo comparator: 2 - 28 days of oral distilled water (5ml) (in addition to standard therapy) and then repeat serum creatinine and vascular study then crossover to intervention (N-acetylcysteine 500mg oral bd) for 28 days after one week washout period with tests repeated again at 4 weeks and 9 weeks.
