Nutritional status of alcoholics of different socioeconomic class.

Most studies concerning the nutritional status of alcoholics have focused on the indigent alcoholic but programs now increasingly consider the working patient. The role of socioeconomic status in determining nutritional status of the alcoholic is further clarified in this study. One hundred patients from an alcoholic population were studied, 50 with low socioeconomic status and 50 with middle or higher socioeconomic status. The nutritional status of these two different socioeconomic groups was examined and compared. The middle-income alcoholic had significantly higher values in weight to height index (P less than .02), the triceps skinfold (P less than .01), the midarm muscle circumference (P less than .05), hematocrit (P less than .01), and epilation force (P less than .001) than the lower-income alcoholic group. Hair-pulling tension was compared in both groups as an index of protein malnutrition. There was a highly significant difference in the two groups.

Increased urinary excretion and prolonged turnover time of folic acid during ethanol ingestion.

The effect of ethanol on the kinetics of folic acid urinary excretion was studied in five chronic alcoholic patients who were maintained in a folate replete state. For 17 days, 95% ethanol was administered orally at 2-h intervals (X9). The folate pool(s) were labeled with the tritium labeled pteroyl glutamic acid at the start of the period of ethanol ingestion and at the start of a control abstinent period. The 24-h urine volume did not change with consumption of ethanol. Total urinary folate excretion was significantly greater by 20 to 40% in four of five patients during the ethanol administration period (p less than 0.05). The fall-off in urinary radioactivity corrected for total folate excretion (dpm/microgram Lactobacillus casei folate) was resolved into a biexponential decay with two distinct slopes. Ethanol caused the slope of the second component to flatten significantly with mean t1/2 of 63.7 days on ethanol versus 9.6 days off (p less than 0.05). These kinetic results are consistent with the known interference by ethanol of folate utilization in a functional tissue pool.

Comparison of fenoprofen calcium, ibuprofen and placebo in primary dysmenorrhea.

This prospective, double-blind, parallel, two clinic study compared fenoprofen calcium, 200 mg; ibuprofen, 400 mg; and placebo in the treatment of pain due to primary dysmenorrhea. By various criteria, the treatment groups, prior to treatment, were not significantly different (P greater than 0.05) in paired comparisons. However, after oral administration of the study medications, the pain scores were significantly greater (P less than 0.05) for the placebo group than for either other group. The posttreatment pain scores for the fenoprofen and ibuprofen treated groups were not significantly different (P greater than 0.05).

Protein-energy malnutrition and liver dysfunction limit the usefulness of the relative dose response (RDR) test for predicting vitamin A deficiency.

The relative dose response (RDR) test was examined for its value in predicting vitamin A nutriture among chronically ill patients with protein-energy malnutrition and among patients with varying degrees of liver dysfunction. The RDR test was elevated (ie greater than 14 per cent) and, thus, predictive of vitamin A deficiency in only 4 out of 9 patients with combined vitamin A deficiency and protein-energy malnutrition. Among 27 patients with liver dysfunction who had vitamin A determinations performed on liver biopsy material, there was no correlation found between the RDR response and the hepatic vitamin A level. Of 12 patients with low hepatic vitamin A levels (less than 100 micrograms/g wet weight), the RDR test was normal in 9 (75 per cent). Inability of the RDR test to predict vitamin A nutriture in patients with protein-energy malnutrition and in patients with liver dysfunction may, in part, be due to inadequate synthesis or release of retinol-binding protein.

Thiamin in the elderly--relation to alcoholism and to neurological degenerative disease.

Status of thiamin in the elderly North American population is reviewed. Most Americans eat sufficient thiamin but about 5% of those over 60 yr old show impaired thiamin status. This is more marked in the poor, those confined in institutions, or those with illness. Thiamin responsive heart disease and Wernicke Korsakoff CNS syndromes occur in the elderly but there is no increased prevalence. Minor heart or neurological syndromes related to thiamin deficiency cannot be identified. The Recommended Dietary Allowance of thiamin provides at least 50% excess thiamin for those over 60 yr old--this amount is adequate. There is no known toxicity for thiamin.

Deficiency of fat soluble vitamins after jejunoileal bypass surgery for morbid obesity.

Significant vitamin A, E, or 25-hydroxy D deficiency occurred in 76% of 40 patients studied up to 6 years after jejunoileal bypass surgery for morbid obesity. Vitamin A was significantly lower in those who had lost 30% of their initial weight than in those who had lost less weight; however, there was no correlation of vitamin A, E, or D levels, time elapsed since surgery, or with daily intake of vitamins as subnormal values were found despite multivitamin supplementation and consumption of twice the recommended daily allowance of vitamin A. Functional derangement of retinal adaptation to darkness secondary to vitamin A deficiency was found in four of nine stable, healthy patients studied at least 18 months after surgery. There was no linear relationship between vitamin A levels and dark adapted final thresholds or with serum albumin, prothrombin time, or degree of steatorrhea. Three patients with abnormal adapted final thresholds were treated with vitamin A. Total daily intake of up to 65,000 IU of vitamin A daily for several months resulted in normalization of function in all.

Impaired acid neutralization in the duodenum in pancreatic insufficiency.

The influence of severe exocrine pancreatic disease on the acid-neutralizing capacity of the duodenum was studied in five patients with pancreatic insufficiency (PI) and six control subjects using duodenal perfusion-marker technique. Hydrochloric acid (0.1 N containing 1% PEG) was infused at constant rates (1.2, 4.5 and 7.0 ml/min) into the duodenum just distal to the duodenal bulb. Samples were aspirated from the tip of the duodenal perfusion tube located at the ligament of Treitz. All samples were analyzed for volume, pH, titrable acidity, PEG and [14C]PEG (gastric marker) determination. Patients with PI demonstrated significantly diminished ability to neutralize various acid loads as compared to controls who virtually completely neutralized acid loads in the range of maximal gastric acid secretion. Exogenous secretin did not significantly improve percent acid neutralized in PI. These data clearly indicate that patients with PI have significantly impaired ability to neutralize even small loads of acid in the duodenum.

Associated liver disease in alcoholic pancreatitis.

Two studies investigating the association of liver disease with acute and chronic pancreatitis in alcoholics are presented. In a retrospective study of 50 patients, no clinical liver disease was found in 9 patients with acute pancreatitis, while 23 (56%) of 41 patients with chronic pancreatitis had liver disease by clinical criteria. Of this latter group, 8 were confirmed histologically; thus 19% of patients with chronic pancreatitis had biopsy-proven cirrhosis. Fifty alcoholic patients with pancreatitis were prospectively evaluated. All who had clinical evidence of liver disease were biopsied. No cases of liver disease were encountered in the 4 patients with acute pancreatitis. Although 28 (60%) cases of clinically diagnosed liver disease were present in 46 patients with chronic pancreatitis, only 20 of these seemed significant (cirrhosis, alcoholic hepatitis, severe fatty liver), for an incidence of 43%. Thus, clinically significant alcoholic liver disease occurs quite frequently in association with alcoholic pancreatitis. This association is meaningful in more effective management of these patients in general and in preoperative assessment of the risk of surgery in particular.

A controlled trial of 6-methylprednisolone in acute alcoholic hepatitis. With a note on published results in encephalopathic patients.

In a prospective double-blind study, 27 patients with alcoholic hepatitis were randomized for 6-methylprednisolone (12 patients) or placebo treatment (15 patients). The mortality was 50% among steroid treated patients and 47% in the control group (P less than .05). The role of liver biopsy feasibility at selection is emphasized since the mortality in this group was 10% as opposed to 71% when the procedure was contraindicated (P less than .01). Complications in the steroid-treated subjects were similar quantitatively and qualitatively to those observed in the control series.
