A 6-month follow-up of nutritional status in institutionalized patients with Alzheimer's disease.

OBJECTIVE: A follow up of nutritional status in institutionalized patients with Alzheimer's disease. DESIGN: Observational study. SETTING: Specialized unit for patients with Alzheimer's disease in Dijon hospital, France. SUBJECTS: Fourteen women, aged 72-92 years. ASSESSMENTS: On admission of patients to the specialized unit for dementia, body weight, body mass index, arm muscle circumference (AMC) and triceps skin fold (TSF) were measured. Serum concentrations of albumin, prealbumin, homocysteine, orosomucoide, calcium, folates, vitamins B12 and B6 and C-reactive protein were recorded. The same clinical and biological measurements were repeated at day 30, 90 and 180. RESULTS: Both mean weight and mean BMI increased throughout the study with significant differences between day 0 and day 90, and day 180 (p<0.01). The weight gain was associated with a significant increase in AMC and TSF (p<0.01 and p<0.001, respectively). There was no significant difference for values of both mean serum levels of albumin and prealbumin between day 0 and day 180. Whatever the period, serum concentrations of folates and vitamin B12 were in the normal range, while mean levels of vitamin B6 were lower than the normal range; For all these values, there was no significant difference between day 0, 30, 90, 180. Mean levels of C-reactive protein and orosomucoide and lymphocyte counts were in the normal range both at admission and day 180. No significant difference was noted between value of homocysteine at admission and at day 180. CONCLUSION: In this special care unit, the patients with Alzheimer's disease who take part in daily activities and particularly preparation of the meal don't lose weight. It is certain that future studies recording food intake and energy expenditure are necessary to explain the benefits in the nutritional status observed in patients showing dementia when they are institutionalized in a special unit.

[Clostridium difficile diarrhea in the very old. Clinical features and course in 21 cases]. / Diarrhée à Clostridium difficile chez le sujet très âgé. Particularités cliniques et évolutives de 21 cas.

OBJECTIVES: Determine the clinical and etiological features of Clostridium difficile diarrhea in elderly subjects. PATIENTS AND METHODS: We retrospectively analyzed 21 cases of C. difficile diarrhea observed in patients at the Dijon geriatric center from January 1994 through December 1995. The diagnosis was established on C. difficile toxin evidenced in fecal matter. RESULTS: There were 13 women and 8 men (mean age 85.9 years). All patients had several underlying disease conditions and were highly dependent. Three outbreaks involving 11 patients were observed. In more than half of the patients, the primary clinical signs were colitis with fever, highly elevated erythrocyte sedimentation rate and high white cell count. Eleven patients also had candidiasis of the digestive tract. All patients had received one or several antibiotics during the 15 days prior to diarrhea. The main antibiotic families were aminopenicillins, cephalosporins and fluoroquinolones. Twenty patients were given specific treatment: imidazoles in 15 cases and vancomycin in 9. Diarrhea was successfully controlled in 14 cases. There were 2 cases of recurrence and 6 patients died after a cascade of complications. C. difficile infection persisted in 2 at death. DISCUSSION: Over recent years C. difficile diarrhea has become a serious problem in geriatric units. Antibiotic therapy is the main risk factor as well as protein-calorie malnutrition, immunodeficiency, and colonic stasis. Morbidity and mortality are high in fragile elderly subjects.
