RESUMEN
INTRODUCTION: PD catheter tip migration is a common complication and a significant cause of catheter malfunction. In this perspective, we present our experience with a new catheter and a new technique that involves the use of a new triple cuff PD catheter and a low entry site in an attempt to prevent PD catheter migration. METHODS: A total of 503 incident PD patients have been studied in more than one PD center over a period of 5 years. RESULTS: During the 5-year follow up we recorded zero percent catheter migration. Other technical complications were poor drainage in 3.4%, omental wrap in 2.8%, early leakage in 3.4%, and catheter replacement in 2.4%. By the end of the study, the one-year PD catheter survival was 97.6%. CONCLUSION: Our new triple cuff PD catheter and our low-entry approach seem to be effective in preventing PD catheter migration and minimizing other mechanical complications.

Very few detailed descriptive studies focusing on peritonitis in patients on peritoneal dialysis (PD) have been published. Most of the current information is available through from either study with the limited number of patients or isolated case reports. We conducted an observational study of our PD-peritonitis database over the past 12 years to study the clinical profile and the outcomes of peritonitis episodes in our PD center. A total of 1123 patients (male: 59.5%) with 319 episodes of peritonitis were identified. Of the patients, 130 (11.6%) were considered immunocompromised (steroid use, failed renal transplant, systemic lupus erythematosus, malignancy) and 468 (41.7%) had diabetes mellitus. The total number of bacterial peritonitis episodes was 319; of these 226 (70.8%) were seen with double cuff Tenckhoff PD catheter and 93 (29.2%) occurred with triple-cuff Saudi PD catheter (P = 0.0001). Of all peritonitis episodes 170 (53.3%) episodes were caused by a single Gram-positive organism, 124 (38.9%) episodes by a single Gram-negative organism, and 25 (7.8%) were polymicrobial. Coagulase-negative staphylococci were responsible for most cases of Gram-positive peritonitis (n = 110, 64.7%), while Escherichia coli was the causative organism in 67 (54.0%) of the single Gram-negative episodes. Peritonitis episodes due to Gram-positive organisms had a better outcome than those caused by Gram-negative bacteria. Fifteen (4.7%) of the 319 episodes resulted in death in 13 patients. In 79 (24.8%) episodes, the patients had to be transferred to hemodialysis because of unresolved peritonitis. Resolution rate was 75.2% (240 episodes) which was influenced by PD catheter type, PD duration and the number of days peritoneal fluid effluent remained above 100 cells/µL. Other modifiable and non-modifiable factors had no effect on the resolution rate. Peritonitis episodes due to Gram-positive organisms had a better outcome than those with Gram-negative or polymicrobial etiology. Peritonitis resolution rates were worse with Staphylococcus aureus and Pseudomonas aeruginosa infections. Diabetes, current steroid use, and exit-site/tunnel infections seemed to have limited influence on the peritonitis outcome. Type of PD catheter (double Tenckhoff vs triple-cuff Saudi catheter), duration of PD and the number of days peritoneal fluid effluent remained >100 cells/µL were the only factors with significant effects on the outcome.

Coronavirus Disease 2019 (COVID-19) is a pandemic disease that increased the burden on health-care system. In the Kingdom of Saudi Arabia, 74,795 cases have been reported until 26 May 2020 and the number of cases is rapidly increasing. The mortality rate of COVID-19 worldwide is 6.37%. Here we report three cases of acute kidney injury (AKI) secondary to pneumonia of severe COVID-19; they were treated with automated peritoneal dialysis (PD) with full recovery. To the best of our knowledge, few reports in the literature have discussed the use of PD in AKI secondary to COVID-19.

BACKGROUND: Ultrafiltration is an alternative strategy to diuretic therapy for the treatment of patients with acute decompensated heart failure. Little is known about the efficacy and safety of peritoneal dialysis in patients with acute decompensated heart failure complicated by acute cardiorenal syndrome. METHODS: We randomly assigned a total of 88 patients with type 1 acute cardiorenal syndrome to a strategy of ultrafiltration therapy (44 patients) or tidal peritoneal dialysis (44 patients). The primary endpoint was the change from baseline in the serum creatinine level and left ventricular function represented as ejection fraction, as assessed 72 and 120 h after random assignment. Patients were followed for 90 days after discharge from the hospital. RESULTS: Ultrafiltration therapy was inferior to tidal peritoneal dialysis therapy with respect to the primary endpoint of the change in the serum creatinine levels at 72 and 120 h (p = 0.041) and ejection fraction at 72 and 120 h after enrollment (p = 0.044 and p = 0.032), owing to both an increase in the creatinine level in the ultrafiltration therapy group and a decrease in its level in the tidal peritoneal dialysis group. At 120 h, the mean change in the creatinine level was 1.4 ± 0.5 mg/dL in the ultrafiltration therapy group, as compared with 2.4 ± 1.3 mg/dL in the tidal peritoneal dialysis group (p = 0.023). At 72 and 120 h, there was a significant difference in weight loss between patients in the ultrafiltration therapy group and those in the tidal peritoneal dialysis group (p = 0.025). Net fluid loss was also greater in tidal peritoneal dialysis patients (p = 0.018). Adverse events were more observed in the ultrafiltration therapy group (p = 0.007). At 90 days post-discharge, tidal peritoneal dialysis patients had fewer rehospitalization for heart failure (14.3% vs 32.5%, p = 0.022). CONCLUSION: Tidal peritoneal dialysis is a safe and effective means for removing toxins and large quantities of excess fluid from patients with intractable heart failure. In patients with cardiorenal syndrome type 1, the use of tidal peritoneal dialysis was superior to ultrafiltration therapy for the preservation of renal function, improvement of cardiac function, and net fluid loss. Ultrafiltration therapy was associated with a higher rate of adverse events.

BACKGROUND: The aim of this paper was to review the feasibility of peritoneal dialysis (PD) in the presence of a permanent suprapubic catheter over a long follow-up period. METHODS: Twelve patients with automated PD and permanent suprapubic catheters were studied for complications over a period of 10 years. RESULTS: In all 12 patients, PD went smoothly. Two of our patients required removal of the PD catheter due to peritonitis. The overall rate of exit-site infection throughout the study was 41.7/patient-month and the difference between patients 60 years or older and those 25 years or younger was not significant (p = 0.3673). The overall peritonitis rate for all patients was 38.3 episode/patient-month, and none of the patients with ventriculoperitoneal shunt (VPS) had peritonitis. All patients with episodes of infection responded well to the proper antibiotics. CONCLUSIONS: The available data supported the feasibility of PD in patients with permanent suprapubic catheters; however, a greater number of patients with a longer follow-up period need to be studied to support our results.
