Effects of the volume of processed plasma on the outcome, arterial pressure and blood procalcitonin levels in patients with severe sepsis and septic shock treated with coupled plasma filtration and adsorption
To understand how coupled plasma filtration and adsorption (CPFA) could influence the time course of the advanced stages of sepsis, mean arterial pressure (MAP) and norepinephrine dosage.
METHODS:
Patients with severe sepsis and septic shock with 652 organ failures not responding to volume resuscitation and vasopressor infusion were treated with CPFA within 8 h of admission to the intensive care unit.
RESULTS:
Thirty-nine patients were treated (median age: 63 years, median SAPS II score: 45) and 28 survived advanced sepsis. In the latter, the median MAP increased and the norepinephrine dosage decreased significantly after CPFA, whereas in the nonsurvivors these values did not change significantly. The volume of treated plasma was significantly higher in survivors than nonsurvivors.
CONCLUSION:
These results suggest a possible existence of a dose-response effect for CPFA. Future studies are therefore recommended to evaluate the efficacy of this treatment and to determine its best timing and intensit
Influence of Timing of Initiation and Volume of Processed Plasma on the Outcome of Septic Shock Patients Treated with Coupled Plasma Filtration and Adsorption
The extracorporeal removal of mediators is a rescue strategy for septic shock patients, which is still under investigation. Several techniques are available: coupled plasma filtration and adsorption (CPFA) combines plasma processing with renal replacement therapy
Coupled Plasma Filtration Adsorption for Treatment of Capillary Leak Syndrome Superimposed to Acute Generalized Exanthematous Pustolosis: A Case Report
Coupled plasma filtration adsorption (CPFA) is an extracorporeal supportive therapy based on nonspecific adsorption of pro- and anti-inflammatory mediators combined with continuous renal replacement therapy. The main field of CPFA application is septic shock, and there are limited data about its efficacy in the treatment of other acute conditions characterized by a dysregulation in immune homeostasis. Capillary leak syndrome (CLS) defines a life-threatening condition sustained by hypercytokinemia and characterized by abrupt onset of increased capillary permeability leading to severe generalized edema and hypovolemic shock refractory to fluid administration. Therapy for CLS is not specific and, at present time, it consists in the use of steroids or intravenous immunoglobulins. We present the case of a 34-year-old woman who developed CLS superimposed to acute generalized exanthematous pustulosis after initiating therapy with hydroxychloroquine for undifferentiated connective tissue disease. CLS did not respond to steroids and intravenous immunoglobulins, while it was successfully treated with CPFA. This observation supports the possible role of CPFA in restoring a proper immunologic homeostasis not only in sepsis but also in other devastating conditions sustained by hypercytokinemia
Adsorption therapy and septic shock: a retrospective study comparing Coupled Plasma Filtration-Adsorption and CytoSorb
Background and Aims: Septic shock is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Excessive release of cytokines and other inflammatory mediators is a key mechanism and cytokines adsorption therapies are applied in this context to restore a balanced immune homeostasis. Different adsorption techniques are available but there are no studies comparing these different adsorption approaches. The aim of this retrospective observational study was to compare Coupled Plasma Filtration Adsorption (CPFA) and CytoSorbTM in terms of hemodynamic and clinical response, mortality and renal function recover
Radiation dose from medical imaging in end stage renal disease patients: a Nationwide Italian Survey
Background and objectives: End stage renal disease (ESRD) patients are exposed to the risk of ionizing radiation during repeated imaging studies. The variability in diagnostic imaging policies and the accompanying radiation doses across various renal units is still unknown. We studied this variability at the centre level and quantified the associated radiation doses at the patient level.
Methods: Fourteen Italian nephrology departments enrolled 739 patients on haemodialysis and 486 kidney transplant patients. The details of the radiological procedures performed over one year were recorded. The effective doses and organ doses of radiation were estimated for each patient using standardized methods to convert exposure parameters into effective and organ doses
RESULTS: Computed tomography (CT) was the major contributor (> 77%) to ionizing radiation exposure. Among the haemodialysis and kidney transplant patients, 15% and 6% were in the high ( 65 20 mSv per year) radiation dose groups, respectively. In haemodialysis patients, the most exposed organs were the liver (16 mSv), the kidney (15 mSv) and the stomach (14 mSv), while the uterus (6.2 mSv), the lung (5.7 mSv) and the liver (5.5 mSv) were the most exposed in kidney transplant patients. The average cumulative effective dose (CED) of ionizing radiation among centres in this study was highly variable both in haemodialysis (from 6.4 to 18.8 mSv per patient-year; p = 0.018) and even more so in kidney transplant (from 0.6 to 13.7 mSv per patient-year; p = 0.002) patients.
Conclusions: Radiation exposure attributable to medical imaging is high in distinct subgroups of haemodialysis and transplant patients. Furthermore, there is high inter-centre variability in radiation exposure, suggesting that nephrology units have substantially different clinical policies for the application of diagnostic imaging studies
