Chronic wounds are a major cause of morbidity and mortality. Approximately 20% to 23% of nonhealing wounds that are refractory to vascular intervention have other causes, including vasculitis, pyoderma gangrenosum, and other autoimmune diseases. The purpose of this article was to review the literature across medical and surgical specialties with regard to refractory chronic wounds associated with vasculitis and autoimmune diseases and to delineate clinical outcomes of these wounds in response to vascular and other interventions.. An electronic search encompassing MEDLINE, PubMed, Cochrane Library, and Scopus was completed using the following search terms: rheumatoid arthritis; systemic sclerosis; systemic lupus erythematosus; antineutrophil cytoplasmic antibody-associated vasculitis; mixed connective tissue disease; antiphospholipid syndrome; pyoderma gangrenosum; thromboangiitis obliterans; cryoglobulinemia; hydroxyurea; sickle cell; atrophie blanche; livedoid vasculitis; cholesterol emboli; calciphylaxis; antiphospholipid antibodies; prothrombotic; combined with the terms: chronic wound and leg ulcer. Full-text articles published in English up to March 1, 2016, that investigated the clinical outcomes of chronic wounds associated with autoimmune diseases were included. Review articles and evaluations of management of chronic wounds were also reviewed. Primary outcomes included in the review were amputation, ulcer healing, reduction in wound size, overall survival, and freedom from reintervention. Owing to the heterogeneity of data reporting among articles, qualitative analysis is also reported.. Vasculitis and autoimmune diseases play a role in 20% to 23% of patients with chronic lower extremity ulcers. Furthermore, patients with autoimmune disease have a significantly high rate of split thickness skin graft failure (50% compared to 97% in patients without autoimmune disease; P = .0002). The management of leg ulcers associated with autoimmune diseases is discussed.. Autoimmune and vasculitic causes should be considered in patients with chronic wounds who do not respond to appropriate vascular intervention and standard local wound care. A multidisciplinary approach with the involvement of rheumatologists allows investigation for underlying systemic disease and improves clinical outcomes for many of these challenging patients.

Sickle cell disease is associated with a decreased life expectancy, half of the deaths occurring in the ICU. We aimed to describe the characteristics of sickle cell disease patients admitted to ICU and to identify early predictors of a complicated outcome, defined as the need for vital support or death.. Retrospective observational cohort study of sickle cell disease patients over a 6-year period.. ICU of a French teaching hospital and sickle cell disease referral center.. Hundred thirty-eight ICU admissions in 119 sickle cell disease patients.. None.. ICU admission was mainly indicated for sickle cell disease-related events, especially acute chest syndrome. Mechanical ventilation, vasoactive drugs, and renal replacement therapy were administered to 25 (18%), 10 (7%), and 10 (7%) episodes, respectively. The complicated outcome group (n = 28; 20%) was characterized by a more aggressive acute disease within the 48 hours preceding ICU admission, with a higher respiratory rate, a more frequent acute kidney injury, and a more sustained drop of hemoglobin (all p < 0.01). All nine deaths (7%) were sickle cell disease related. None of the sickle cell disease baseline characteristics predicted accurately a complicated outcome. In multivariate analysis, hemoglobin less than or equal to 7.8 g/dL (odds ratio, 3.6; 95% CI, 1.1-11.9), respiratory rate more than or equal to 32 cycles/min (odds ratio, 5.6; 95% CI, 1.8-17.2), and acute kidney injury on ICU admission (odds ratio, 11.5; 95% CI, 2.5-52.6) were independently associated with a complicated outcome.. Sickle cell disease patients are at high risk of complications when admitted to the ICU. A sustained drop of hemoglobin, acute respiratory distress, and kidney injury at admission are strong predictors of a complicated outcome.
