Patients with acute renal failure due to sepsis have a worse prognosis than those with non-septic acute renal failure. Sepsis and the above-defined predictive factors are to be considered in studies on prognosis of ARF patients. Our results suggest that the use of biocompatible membranes may reduce significantly mortality in these patients.
Quality of life measured with a health-related quality of life scale and a satisfaction scale 6 months after an ICU stay depended on the admission diagnosis. Different dimensions of quality of life were variably affected.
The influence of patients' age on survival, level of therapy and length of stay was analyzed from data collected in 792 consecutive admissions to eight intensive care units. Mortality rate increased progressively with age; over 65 years of age, it was more than double that of patients under 45 years (36.8% versus 14.8%). However, mortality rate in patients over 75 years was equal to that observed in the 55 to 59 years group. There was a significant relationship between age and acute physiology score (APS) and the influence of age upon outcome decreased when APS increased. The number of TISS (therapeutic intervention scoring system) points delivered to patients increased slightly but significantly with age (r = 0.14). Standard care was responsible for the main part of this increase. Both in survivors and in non-survivors the length of stay was not different comparing the stay of the oldest patient with that of the younger age groups. We conclude that, in ICU patients, age is an important factor of prognosis but not as important as the severity of illness, and that there is no major difference in outcome of patients over 65 years of age compared to the entire study group of ICU patients.
Nocardia infection classically occurs in immuno-compromized patients. Only a few cases of mediastinal infection due to this pathogen have been described in the literature. We report a patient who developed mediastinitis due to Nocardia asteroides after cardiac transplantation. The treatment was surgical debridement, dressing, sugaring and antibiotic therapy. The emergence of a severe acute renal failure possibly induced by drug interaction between Cyclosporin, cyclines and aminoglycosides, led us to modify the antimicrobial treatment. The intravenous use of Imipenem 2 g per day and Ciprofloxacin 400 mg per day for four weeks and then oral Ciprofloxacin 1.5 g per day for 1 year, was effective and allowed a good outcome, without any drug interaction with Cyclosporin, adverse effect, graft rejection episode or infection relapse.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
