Nutritional support of the hospitalized patient

Serum lipids of pemphigus foliaceus patients on long-term glucocorticoid therapy

Endemic pemphigus foliaceus, and long-term corticotherapy may affect serum lipid levels. The aim of this study was to compare serum lipids of pemphigus foliaceus patients on glucocorticoid therapy to a healthy control group. Fifteen patients receiving prednisone (0.33 +/- 0.22 mg/kg) for at least 12 months and 15 controls were submitted to 48-h food intake records, anthropometry, and biochemical measurements. Data were compared by chi2, Mann-Whitney and Student "t" tests. The groups were matched for gender, age, weight, body mass index, arm circumference and triceps skin fold. No differences were observed in relation to energy, fat, protein and carbohydrate daily intakes, total cholesterol, HDL, LDL, uric acid, and serum creatinine levels. Pemphigus foliaceus patients had higher triglyceride [159 (64-371) vs. 100 (45-133) mg/dl], VLDL [32 (13-74) vs. 20 (9-114) mg/dl] and ESR [44 (9-87) vs. 7 (1-30) mm/h] levels than controls, probably due to metabolic effects of inflammatory disease and corticotherapy.

Nutritional support in the postoperative period

Nutritional support is used frequently as a treatment modality in the postoperative patient. Indications for nutrition support, patient selection, mode of administration, contents of solutions and complications of therapy are issues that the consulting internist must address. The role of a nutrition support team and optimal communication between the consultant and members of the surgical staff are emphasized.

Nutritonal evaluation of pemphigus foliaceus patients on long term glucocorticoid therapy

Our objective was to compare food intake and nutritional status of Pemphigus Foliaceus patients (PG) on long term glucocorticoid therapy to a Control Group (CG). Fourteen PG female inpatients receiving prednisone (0.33 +/- 0.22mg/kg) for at least 12 months and twelve CG subjects were submitted to nutritional evaluation, including anthropometry, urinary creatinine determination and serum biochemical measurements, besides 48-h-based food intake records. Groups were compared by Chi-square, Mann-Whitney and "t" tests. PG patients and CG were paired, respectively, in relation to age (24.7 +/- 14.1 vs. 22.0 +/- 12.0 years), body mass index (25.8 +/- 6.4 vs. 24.0 +/- 5.6kg/m2), daily protein intake (132.9 +/- 49.8 vs. 95.2 +/- 58.9g), and serum albumin (median; range) (3.8; 3.5-4.1 vs. 3.8; 3.6-5.0g/dl). However, PG patients had lower height-creatinine index (64.8 +/- 17.6 vs. 90.1 +/- 33.4%), and higher daily energy (3080 +/- 1099 vs. 2187 +/- 702kcal) and carbohydrate (376.8 +/- 135.8 vs. 242.0 +/- 80.7g) intakes. Despite high food, protein and energy consumption, PG patients on long term glucocorticoid therapy had lower body muscle mass than controls, while showing high body fat stores. These findings are possibly related to combined metabolic effects of long term corticotherapy and inflammatory disease plus corticosteroid-induced increased appetite.

Pressure sores and tube feeding in patients with a fracture of the hip: a randomized clinical trial

Pressure sores are a frequent problem, especially in elderly patients. Nutritional status may influence the incidence, progression and severity of pressure sores, data, however, are contradictory (1). The purpose of this study was to determine the effect of supplemental feeding on the nutritional status and the development and severity of pressure sores. The effect of supplemental feeding overnight (tube +) on patients with a fracture of the hip and a high pressure-sore risk score, was studied in a randomized clinical trial. The control group (tube -) had no supplemental feeding. After informed consent, 140 patients were randomized, and 129 of these took part in the trial (62 tube +, and 67 tube -). Protein and energy intake, haemoglobin, serum albumin, total serum protein and pressure-sore grade were measured at admission and after 1 and 2 weeks. Of the 62 patients randomized for tube feeding (tube +), only 25 tolerated their tube for more than 1 week and 16 for 2 weeks. Nevertheless, energy and protein intake was significantly higher in the tube + group (P < 0.001). This, however, did not significantly influence total serum protein, serum albumin and development and severity of pressure sores after 1 and 2 weeks. Comparison of the actually tube fed group (n=25 at 1 week, n = 16 at 2 weeks) and the control group showed a 2-3 times higher protein and energy intake (P < 0.0001), and a significantly higher total serum protein and serum albumin after 1 and 2 weeks in the actually tube fed group (all P < 0.001). Pressure-sore development and severity were not significantly influenced in the actually tube fed group. We conclude that we were not able to show a significant decrease in development and severity of pressure sores, because the nasogastric tube for supplemental feeding was not well tolerated in this patient group. Nevertheless, tube feeding overnight does result in a significant higher protein and energy intake, and has a significant effect on nutritional status in the actually tube-fed group. Other means of supplemental feeding will have to be used in order to answer the question of whether supplemental feeding can decrease development and severity of pressure sores.
