The nutritional status and treatment of patients with hyperemesis gravidarum.

OBJECTIVE: The objective of this study was to evaluate the nutritional status of patients with hyperemesis gravidarum and the effect of a treatment regimen administered during hospitalization. STUDY DESIGN: This was a descriptive, controlled study of 20 patients with hyperemesis gravidarum whose nutritional status was assessed and compared with that of 20 pregnant, nonvomiting matched controls. Blood nutrient status was reassessed after 10 days of treatment with an intravenous saline solution containing a multivitamin preparation and again at day 20. RESULTS: Mean dietary intake of most nutrients fell below 50% of the recommended dietary allowances and differed significantly (p < 0.01) from that of controls. More than 60% of the patients had suboptimal biochemical status of thiamine, riboflavin, vitamin B6, vitamin A, and retinol-binding protein. Vitamin C, calcium, albumin, hematocrit, and hemoglobin values were significantly higher in those patients where the duration of vomiting had been longer, suggesting the presence of dehydration. Treatment was associated with cessation of vomiting and improvement in blood nutrient status. Pregnancy outcome was favorable in all patients. CONCLUSION: The hyperemetic pregnant patient is at nutritional risk; prompt initiation of corrective therapy is recommended.

Failure to thrive and its relationship to serum vitamin A levels and diet.

Serum vitamin A and retinol-binding protein (RBP) levels were determined in a group of 34 children between 1 and 4 years of age with failure to thrive and in 34 age- and sex-matched controls. Both groups of children were also assessed in respect of anthropometry and diet. Vitamin A levels in patients (0-32.2 micrograms/100 ml; median 16.9 micrograms/100 ml) did not differ significantly from controls (6.4-47.2 micrograms/100 ml; median 16.1 micrograms/100ml). Fourteen patients (42%) and 4 controls (12%) had vitamin A levels below 10 micrograms/100 ml. RBP levels in patients (0.45-3.50 mg/100 ml; median 2.17 mg/100 ml) also did not differ significantly from those in controls (1.21-3.66 mg/100 ml; median 2.06 mg/100 ml). No clinical features of vitamin A deficiency were detected. Weight and height for age, weight for height, mid-upper arm circumference and head circumference differed significantly between patients and controls (P < 0.0001 in each instance). Although within the recommendations for intake, patients had a significantly lower intake of the essential fatty acid C 18:2 (N = 6) (linoleic acid) and vitamin A. In view of the current proposed relationship between vitamin A status and infectious diseases, the prevalence of biochemical vitamin A deficiency in children in the Cape Town community studied may contribute to the morbidity and mortality associated with infectious diseases in the area to a greater degree than has been suspected.

Fat-soluble vitamin concentration in chronic alcohol-induced pancreatitis. Relationship with steatorrhea.

In order to study the fat-soluble vitamin concentration of patients with chronic alcohol-induced pancreatitis (CAIP) we measured vitamins A and E, total lipids, and retinol-binding protein (RBP) in the plasma of 44 patients with CAIP and 83 controls (44 healthy controls; 39 Crohn's disease patients). Mean plasma vitamin E and vitamin E/total lipid ratio were significantly lower in CAIP when compared with either control or Crohn's disease groups. A low vitamin E/total lipid ratio was found in 75% of CAIP patients (91% with steatorrhea) and a ratio less than 1.0 was virtually 100% predictive of steatorrhea. The mean plasma vitamin A level for the CAIP group was significantly lower (overall 16%, 38% with steatorrhea) than in controls. Patients with CAIP show subnormal plasma levels vitamin E more often as compared to vitamin A. Further, the plasma vitamin E/total lipids ratio may be a sensitive and practical means in the detection and follow-up of steatorrhea in these patients.

Nutrition status of the elderly in Anogia, Crete, Greece.

General health and nutritional status of 167 free-living elderly Greek (aged 65-91 years) were assessed. The most prevalent diseases/symptoms encountered were related to respiratory, gastrointestinal, musculoskeletal and vascular systems (hypertension). Most subjects were socially active. Body mass index was < 20 and > 25 Kg/m2 in 7 and 57% of the subjects, respectively. Systolic blood pressure was significantly higher in women than in men, and as a group, 18 and 42%, respectively, had diastolic blood pressures > 90 and systolic blood pressures > 160 mmHg. Anemia and hypoalbuminemia were detected in < 5% of the population. Total fat intake was 40-45% of total energy intake and most of it came from monounsaturated fat. Hypercholesterolemia (> 6 mmol/L) was present in 32% of subjects. The percentages of men who smoked (66%) or drank (68%) were significantly higher than those of women (2 and 1%, respectively). Dietary intake data were compared with US recommended dietary allowances (RDA) for elderly. Daily energy and protein intakes were lower than the US RDA levels; calcium intake was > 50% of the US RDA, while magnesium and vitamin B6 levels were < 50% of the US RDA. Vitamin C intake was much higher than that of the US RDA. Mean thiamin, vitamin A, riboflavin and iron intakes were below the US RDA, while fiber intake was < 50% of the corresponding US estimate. Phosphorus was higher than the US RDA in men, while lower for women. Sodium intakes exceeded those recommended, while potassium levels were higher than those recommended in males, and lower in females.(ABSTRACT TRUNCATED AT 250 WORDS)
