Background
PD-associated peritonitis is a complication that impacts the morbidity and mortality of patients.The ISPD recommends diagnosing peritonitis when at least two of the following criteria are met: clinical features such as abdominal pain or cloudy dialysis effluent,dialysis effluent WBC > 100/µL with > 50% PMN,or positive dialysis effluent culture.The Spanish Society of Nephrology suggests using a urine dipstick for early diagnosis based on a new strip designed to test PD fluid.
Methods
A prospective study was conducted at the Hospital Universitario Dr. José Eleuterio González, evaluating consultations for PD-associated peritonitis from the emergency department to the nephrology department during August 2022 through February 2023. After a 2-hour exchange, samples were taken the strip testing (Siemens multistix10 SG) were to the laboratory for cytochemical analysis, culture.The strip results were read after a waiting time of 2 minutes and were interpreted by a nephrologist.
Results
30 patients were screened, confirming the diagnosis of PD-associated peritonitis based on the strip and cytochemical results.The demographic data shown in Figure1.The strip showed a sensitivity of 73% and specificity of 100% when using a cutoff of 3 crosses. However,these values changed when using a cutoff of 2 crosses,resulting in a sensitivity of 95% and specificity of 100%.
Conclusion
Urine dipsticks are feasible, and cheap tools that can be useful for the diagnosis of PD-associated peritonitis with great sensibility and specificity saving time for the initiation of the antibiotic.It also helps conserve resources and enables patients to continue their treatment outside the clinic using a simple method.
