Blood eosinophil numbers may be elevated in allergy, inflammatory bowel disease and eosinophilic esophagitis. The aim of this study was to examine whether circulating eosinophils display distinct phenotypes in these disorders and if different patterns of eosinophilic chemoattractants exist. Blood eosinophils from patients with symptomatic eosinophilic esophagitis (EoE; n = 12), ulcerative colitis (n = 8), airway allergy (n = 10) and healthy controls (n = 10) were enumerated and their surface markers analyzed by flow cytometry. Plasma levels of pro-eosinophilic cytokines were quantified in parallel. Data were processed by multivariate pattern recognition methods to reveal disease-specific patterns of eosinophil phenotypes and cytokines. EoE patients had higher numbers of eosinophils with enhanced expression of CD23, CD54, CRTH2 and CD11c and diminished CCR3 and CD44 expression. Plasma CCL5 was also increased in EoE. Although allergic patients had increased interleukin (IL)-2, IL-3, IL-5 and granulocyte macrophage colony-stimulating factor plasma concentrations, their blood eosinophil phenotypes were indistinguishable from those of healthy controls. Decreased eosinophilic expression of CD11b, CD18, CD44 and CCR3, but no distinctive pattern of eosinophil chemoattractants, characterized ulcerative colitis. We propose that eosinophils acquire varying functional properties as a consequence of distinct patterns of activation signals released from the inflamed tissues in different diseases.

Poor perineal wound healing and infections after proctectomy surgery cause a significant proportion of physical and psychological morbidities, such as pain, leakage, and abscesses. In the long run, some of these symptoms will lead to extended periods of hospitalization. These kinds of postoperative complications are also associated with delays in possible chemotherapy treatment. The aim of this study was to describe patient experiences of perineal wound infections following proctectomy due to rectal cancer, and the importance of the communication with and the self-care support from the nurse for these patients. Five women and five men (61–87 years, median age 71 years) were included and interviewed. A qualitative content analysis of the interviews was carried out and the following main categories emerged: “Managing postoperative complications,” “Being independent,” “Feeling safe,” and “Accepting the situation.” A perineal wound infection after a proctectomy is devastating for the individual patient. The limitations and changes to the patients’ lives turn into new daily routines, which force them to find new ways to live and to accept the situation. For many of them, the infections remained for several months and, sometimes, for years. The ability to lead an independent life is drastically reduced, but through continuity in care it is possible to create a feeling of safety. Information, communication, and self-care support are all important and valuable factors for recovery. Specialized care containing an action plan is therefore needed in clinical practice to reduce the number of perineal wound infections postoperatively and should be initiated when the patient is discharged from the ward and continue until recovery.
