Six-month mortality risks in long-term care residents with chronic ulcers

INTERNATIONAL WOUND JOURNAL, Issue 5 2008
Paul Y Takahashi
Abstract Chronic ulcers are a common problem in long-term care. Residents with ongoing ulcers are often frail and at risk for mortality. This study evaluated the relationship between wound characteristics and other health predictors with 6-month mortality in nursing home residents. The subjects included were nursing home residents seen by the wound consult service from 1998 to 2007 with an ongoing chronic ulcer. This was a retrospective cohort study. Data were manually and electronically abstracted for each resident. Six-month mortality was collected as the primary outcome. Statistical comparisons were made using logistic regression with a final multivariant model. Four hundred and forty residents were seen with 411 records reviewed. Ulcer area was not associated with mortality; however, chronic ulcer number was associated with 6-month mortality with an odds ratio of 1·32 (95% CI 1·07,1·63). Other significant risk factors included heart failure, dementia, cancer, depression and blindness with all factors having an odds ratio greater than 1·75. Higher haemoglobin and venous insufficiency were protective of 6-month mortality. Ulcer number is an important predictor for 6-month mortality. The presence of multiple ulcers and comorbid health concerns may influence discussion of prognosis for healing and for potential end of life discussions. [source]

Abstract Objectives Erythropoietin has anti-oxidative and anti-inflammatory activity. We wanted to evaluate its activity in preventing damage to the gastric mucosa. Methods We examined the protective effect of erythropoietin on indometacin-induced gastric mucosa damage in the rat stomach and compared its potency with that of famotidine. We also measured effects on oxidant and antioxidant parameters in the rat stomach. Key findings Famotidine and erythropoietin 2500 and 5000 IU/kg reduced the ulcer area by 98%, 31% and 58%, respectively, compared with the indometacin group. Superoxide dismutase activity and glutathione level were decreased and myeloperoxidase activity increased in the indometacin group compared with healthy rats. Famotidine and erythropoietin at all doses increased superoxide dismutase and glutathione levels significantly compared with the indometacin group. Myeloperoxidase activity was decreased by erythropoietin and famotidine. Conclusions These results support the view that erythropoietin counteracts the effects of indometacin in inducing gastric ulcer and could be used as a an antiulcer compound. Its antiulcer effect is less potent than that of famotidine. The antiulcerogenic effects of erythropoietin may be related to its intrinsic ability to sustain the activities of free-radical scavenging enzymes and the bioavailability of glutathione. [source]

The effect of hyperprolactinaemia, induced by two or four pituitary homografts under the kidney capsule, on gastric and duodenal ulcers has been studied. The acute gastric ulcer models used were pylorus ligation, indometacin-induced and ethanol-induced gastric ulcers. Chronic gastric ulcers were induced using acetic acid and duodenal ulcers by mercaptamine hydrochloride. After pylorus ligation, there was an approximate 30,40% increase in gastric secretion, a significant increase in total acidity (P < 0.01) and in the ulcer index (P < 0.01) in rats bearing pituitary homografts under the kidney capsule when compared with the sham-operated control. Hyperprolactinaemia did not affect the formation of ethanol-induced gastric ulcers but showed a 40% reduction in the development of indometacin-induced gastric ulcers. It also produced a 20% increase in the ulcer index in acetic acid-induced chronic gastric ulcers and a 30% increase in ulcer area in mercaptamine-induced duodenal ulcers. Our results showed that hyperprolactinaemia induced gastric acid secretion and thereby aggravated gastric and duodenal ulcers in rats. Hyperprolactinaemia did not affect gastric cytoprotection.

Treatment of severe scleroderma skin ulcers with recombinant human erythropoietin

Summary Systemic sclerosis (SSc) is frequently complicated by skin ulcers, often unresponsive to traditional treatments. A preliminary evaluation of the effects of recombinant human erythropoietin (rHuEPO) was carried out in 14 patients with SSc with nonhealing, severe cutaneous ulcers. Patients received rHuEPO subcutaneously at a dosage of 150 IU/kg 3 times weekly for 2 weeks, twice weekly for the next 2 weeks, and then once weekly for 1 month. At follow-up 3,6 months from the beginning of the treatment, six patients showed complete resolution of the skin ulcers, while a significant reduction (> 60%) in lesional areas was obtained in the other eight patients (mean ± SD ulcer area reduced from 27.6 ± 28 to 5.3 ± 7.8 cm2; P < 0.005). Moreover, patients' quality of life significantly improved (pain, as measured on visual analogue scale reduced from 96 ± 5 to 46 ± 17 points; P = 0.0001; disability as measured by the Health Assessment Questionnaire,Disability Index reduced from 1.6 ± 0.5 to 0.9 ± 0.4 points; P = 0.0001). The rHuEPO may represent a novel treatment of nonhealing scleroderma skin ulcers, suggesting some important aetiopathological implications. [source]
