| dc.description.abstract | Introduction and aims: Patients undergoing percutaneous endoscopic gastrostomy (PEG) may present protein-energy malnutrition, anemia and deficiencies of hematopoietic factors, e.g., iron, folate and vitamin B12. There are no comprehensive studies on anemia or other hematological changes in PEG-patients. Our aim was to evaluate the hematological status of dysphagic patients that had undergone PEG and its association with clinical outcome. Methods: This research comprises a retrospective study of patients followed by our Artificial Feeding Team, submitted to PEG from 2010 to 2018. Patients were divided into two etiological groups: neurological dysphagia (ND) and head/neck or esophageal disorders (HNE). Laboratory data included serum albumin, hemoglobin, mean corpuscular volume, ferritin, transferrin, iron, vitamin B12 and folate. Survival after PEG was recorded in months, until death or December 2018. Results: We evaluated 472 patients; 250 (53%) presented anemia at the moment of gastrostomy, mostly normocytic (n = 219), with laboratory data suggestive of anemia of chronic disease (ACD). Six patients (1.3%) presented vitamin B12 deficiency and 57 (12.1%) presented folate deficit. No statistically significant difference in hemoglobin was found between the etiological groups (p = 0.230). Folate and vitamin B12 levels were lower in the HNE group (p < 0.01). A positive correlation between hemoglobin and survival was present (p < 0.01, r = 0.289), and hemoglobin levels were lower in the deceased population (p < 0.01). Conclusion: Anemia is frequent in PEG-patients, mostly with the features of ACD or multifactorial. It is associated with significant decrease in survival and may be viewed as a marker of severe metabolic distress, signaling poor outcome. | eng |
