ABSTRACT
Contrast medium-induced nephropathy (CIN) is a leading cause of acquired acute kidney injury and has been associated with prolonged hospitalization and adverse clinical outcomes. This study aimed to determine if omega 3 fatty acids reduce the risk of CIN in patients with chronic kidney disease undergoing coronary angiography. A total of 130 consecutive patients undergoing coronary angiography were randomly assigned to one of two groups as follows: 67 patients were assigned to the N-acetylcysteine (NAC; 1200 mg) and 63 patients were assigned to the omega 3 fatty acid (4 g). Both drugs were administered orally twice per day one day before and on the day of contrast administration. Of the 130 patients enrolled in this study, 10 (7.7%) experienced an increase of at least 0.5 mg/dL (44 µmol/L) in serum creatinine levels 48 h after administration of the contrast agent including 5 of the 67 patients in the NAC group (7.5%) and 5 of the 63 patients in the omega 3 fatty acids group (7.9%; P = 0.919). There were no significant differences in the need for renal replacement therapy (3.0% vs. 9.5%, P = 0.121) or in the mortality rate (3.0% vs. 6.3%, P = 0.361) between the two groups. Short-term prophylactic omega 3 fatty acid treatment with hydration does not reduce the risk of CIN in patients with chronic kidney disease undergoing coronary angiography.

OBJECTIVES: To detect the incidence of and risk factors for infections among patients with end-stage renal disease (ESRD) undergoing peritoneal dialysis (PD). METHODS: A retrospective cohort study was conducted at the PD unit of King Fahad Medical City. End-stage renal disease patients above the age of 12 years who were undergoing PD management between January 2006 and March 2016 were included. RESULTS: One hundred PD patients were enrolled in the study and examined over a total observation period of 2,553 patient-months. The leading ESRD etiology was hypertension (26.3%). The mean duration of PD was 28.05 months. A total of 45 patients developed 101 episodes of technique-related infections (TRIs). Peritonitis represented the majority of these episodes (90 episodes), with an overall rate of one episode per 28.3 patient-months. TRIs were mostly caused by coagulase-negative staphylococci. A total of 12 patients developed non-technique related infections (NTRIs). There was a statistically significant difference between patients with TRI and non-infected patients regarding the presence of diabetes and duration of dialysis. No peritonitis-related deaths were noted. In total, 21 patients continued on PD and 18 patients were shifted to hemodialysis (HD). Conclusion: In our setting, ESRD patients undergoing PD are more susceptible to TRIs than NTRIs. Diabetes increases the risk of developing TRIs. The high incidence of coagulase-negative staphylococcal TRI suggests touch contamination.
