[Nutritional status assessment in 57 hospitalized aged patients: impact of the causal disease]. / Evaluation de l'état nutritionnel de 57 malades âgés hospitalisés: influence de la pathologie causale.

PURPOSE: To study the nutritional status in elderly patients hospitalized for rehabilitation and to compare it among patients with hip fracture and those with medical care. METHODS: Patients were nutritionally assessed upon admission (d0) to our unit by measurement of anthropometric, biological parameters and dietary intake. Thirty-seven patients were operated for hip fracture (group I) and 21 were hospitalised for medical disease (group II). Nutritional status was compared in the two groups on d0 and was evaluated after one month (d30) in the operated group. RESULTS: No significant difference could be observed for any anthropometric or biologic (albumin, transthyretin and transferrin) in the two groups. Daily food intake related to body weight was much the same in both groups (31 kcal/kg). C-reactive protein and orosomucoid levels were above the reference range in both groups. Hip fracture operated patients had higher orosomucoid than non-operated ones (1.50 +/- 0.4 versus 1.14 +/- 0.4 g/L; P = 0.002). One-month follow-up of nutritional status performed in 31 operated patients showed a significant decrease in TST and MAC (respectively p = 0.02 and p = 0.007) and in orosomucoid (p = 0.003) although daily food intake increased. CONCLUSION: Twenty-eight percent of patients were undernourished upon admission in the unit. A moderate inflammatory state still remained in all our patients, particularly in those who had undergone surgery. This inflammatory state persisted two months after surgery.

Serum levels of insulin-like growth factor-1 in the three months following surgery for a hip fracture in elderly: relationship with nutritional status and inflammatory reaction.

BACKGROUND AND AIMS: Serum IGF-1 level declines with advancing age and is a reliable index of protein-energy undernutrition in elderly patients in a metabolically stable condition. We have examined the value of IGF-1 as an indicator of malnutrition in elderly patients during recovery within 1 month after surgery for a hip fracture and we have studied the relationship between changes in IGF-1 levels, nutritional status and inflammatory reaction during 2 month follow up. STUDY DESIGN: Forty elderly patients (mean age 84.0+/-1.9) were nutritionally assessed upon admission to our rehabilitation unit (D0) then monthly (D30-D60) by measurement of anthropometric and biological parameters. Two groups of patients were defined on the basis of mid-arm circumference (MAC) and tricipital skinfold thickness (TST) measurement at D0: group 1, undernourished (n=13) and group 2, normally nourished (n=27). Changes in anthropometric and biological parameters during the study were compared between these two groups of patients. RESULTS: IGF-1 level was significantly lower in group 1 (79.5+/-9.1 vs 108+/-8.6 ng/ml, P<0.05) while usual serum protein levels were in the same range in the two groups. Orosomucoid level significantly decreased during 2 month follow-up in group 2 (P<0.01), CRP level decreased but not significantly. TST and MAC decreased in group 2 (respectively P<0.02 and P<0.05) while anthropometric parameters tended to slightly increase in group 1 in relation with an increase in caloric intake (P<0.05). IGF-1 level increased significantly during the study in group 2 (P<0.05) and was significantly lower in patients with complications occurring between D0 and D30 in comparison with patients without complications (respectively P<0.05 at D0, P<0.02 at D30). IGF-1 level correlated with body mass index, MAC, TST, muscle midarm circumference, albumin and transthyretin levels. Changes in IGF-1 levels positively correlated with those in transthyretin levels and negatively with those in orosomucoid levels. CONCLUSION: IGF-1 level seems a reliable index of protein-energy under-nutrition in elderly patients in the recovery period after surgery for a hip fracture. This marker is influenced by the inflammatory reaction. Decline of inflammatory reaction, rather than change in nutritional status, is responsible for the variation in IGF-1 level during a 2 month follow-up.

Nutritional status and energy expenditure in elderly patients with recent hip fracture during a 2-month follow-up.

A 2-month follow-up of nutritional status was performed in forty elderly patients with recent hip fracture. Patients were nutritionally assessed on admission to our rehabilitation unit (day 0), then monthly (day 30, day 60) by measurement of resting energy expenditure (REE), anthropometric, impedance and biological variables. Patients were defined as undernourished (n 13) or normally nourished (n 27) on the basis of mid-arm circumference (MAC) and triceps skinfold thickness (TST) measurements. Seven patients recovered a walking autonomy and were discharged from the hospital before day 30 (group I) whereas thirteen patients were discharged after day 30 (group II); twenty patients remained in the study at day 60 (group III). MAC and TST decreased in normally nourished patients from group III throughout the study whereas they did not change in group II or in undernourished patients from group III. REE values in relation to fat-free mass were increased compared with normal values and were similar in the three groups on day 0; they did not change during the study. Daily energy intake in relation to body weight was higher in group I and increased in group II and in undernourished patients from group III throughout the study. In contrast, it was below the recommended value at day 0 and it did not significantly improve in normally nourished patients from group III. Serum albumin, transthyretin and transferrin levels on day 0 were below reference intervals in the three groups. Albumin levels increased in group III throughout the study. Inflammatory proteins decreased in groups II and III, with C-reactive protein levels returning to normal values in group II by day 30 and in group III at day 60, while orosomucoid levels did not become completely normal over this period. Our findings indicate no improvement in nutritional status in undernourished patients after surgery for recent hip fracture, despite an adequate energy intake. An insufficient spontaneous energy intake for normally nourished patients was associated with a delayed favourable outcome resulting in a prolonged duration of hospitalization. A hypermetabolic state persisted during the 3 months after surgery.

Aging, energy expenditure and nutritional status: evidence for denutrition-related hypermetabolism.

Resting energy expenditure (REE) and nutritional status have been evaluated in 39 elderly inpatients (mean age 84.0 +/- 6.9 years). The nutritional status declined with aging as shown by significant negative correlations between age and, respectively, weight (p < 0.001), fat free mass (FFM) (p < 0.01) and body mass index (BMI) (p < 0.01). The best prediction for REE when considering the whole population was given by FFM (p < 0.001). Increased REE was observed in patients after recent surgery, related to an inflammatory state, as shown by increased plasma levels of C-reactive protein and orosomucoid. Irrespectively of the inflammatory state, REE was also found to be related to the nutritional status: patients who showed a BMI < 20 had higher REE than patients with a BMI > 20 (28.4 +/- 1.3 vs. 22.1 +/- 0.7 kcal/kg of body weight; p < 0.001; 35.7 +/- 1.6 vs. 30.9 +/- 1.0 kcal/kg of FFM; p < 0.02). These results increasingly suggest that elderly patients may suffer from denutrition relevant to hypermetabolism.

[Enteral nutrition in elderly patients]. / La nutrition entérale chez les sujets âgés.

In elderly subjects, enteral nutrition makes it possible to alleviate anorexia by preserving the venous system without requiring bedrest for the patient, can be performed in his home, but this method exposes the patient to digestive reflux side-effects and minor reactions whose incidence may be kept to a minimum by using the correct technique.

[Complications of digestive involvement in CRST syndrome. 3 cases (author's transl)]. / Complications des localisations digestives du syndrome de Thibierge-Weissenbach (syndrome CRST). 3 observations.

In CRST syndrome, latent oesophageal involvement is common but not usually associated with any clinical manifestations. Involvement of the small intestine is rare. In three patients there occurred severe complications related to digestive involvement in the condition. In one case, involvement of the small intestine was associated with functional obstruction. In the other two patients, oesophageal involvement progressed to very tight stenosis of the lower end of the eosophagus. The generally accepted bening nature of this form of scleroderma must therefore be questioned.
