A Veterans Affairs cooperative study involving 273 male patients was performed to evaluate efficacy of oxandrolone in combination with an enteral food supplement in severe alcoholic hepatitis. All patients had some degree of protein calorie malnutrition. On an intention-to-treat basis, only minimal changes in mortality were observed. However, in patients with moderate malnutrition mortality on active treatment at 1 mo was 9.4% compared with 20.9% in patients receiving placebo. This beneficial effect was maintained so that after 6 mo on active treatment 79.7% of patients were still alive, compared with 62.7% of placebo-treated patients (p = 0.037). Improvements in both the severity of the liver injury (p = 0.03) and malnutrition (p = 0.05) also occurred. No significant improvement was observed with severe malnutrition. To better determine the effect on therapeutic efficacy, we compared results with those from a nearly identical population (cooperative study 119) treated with oxandrolone but not given the food supplement. Patients were stratified according to their caloric intake (greater than 2,500 kcal/day was considered adequate to supply energy needs and promote anabolism). For patients with moderate malnutrition and adequate caloric intake, oxandrolone treatment reduced 6-mo mortality (4% active treatment vs. 28% placebo [p = 0.002]). For patients with moderate malnutrition and inadequate calorie intake, oxandrolone had no effect on mortality (30% active treatment vs. 33% placebo). In cases of severe malnutrition, oxandrolone had no effect on survival. However, adequate caloric intake was associated with 19% mortality, whereas patients with inadequate intake exhibited 51% mortality (p = 0.0001). These results indicate that nutritional status should be evaluated in patients with alcoholic hepatitis. When malnutrition is present, vigorous nutrition therapy should be provided, and in patients with moderate malnutrition oxandrolone should be added to the regimen.

The optimal management of severe ascites in patients with alcoholic cirrhosis has not been defined. in a 5 1/2-year study, we randomly assigned 299 men with alcoholic cirrhosis, who had persistent or recurrent severe ascites despite a standard medical regimen, to receive either intensive medical treatment or peritoneovenous (LeVeen) shunting. We identified three risk groups: Group 1 had normal or mildly abnormal results on liver-function tests, Group 2 had more severe liver dysfunction or previous complications, and Group 3 had severe prerenal azotemia without kidney disease. For the patients who received the medical treatment and those who received the surgical treatment combined, the median survival times were 1093 days in Group 1, 222 days in Group 2, and 37 days in Group 3 (P less than or equal to 0.01) for all comparisons). For all the groups combined, the median time to the resolution of ascites was 5.4 weeks for medical patients and 3.0 weeks for surgical patients (P less than 0.01). Within each risk group, mortality during the initial hospitalization and median long-term survival were similar among patients receiving either treatment. However, the median time to the recurrence of ascites in Group 1 was 4 months in medical patients, as compared with 18 months in surgical patients (P = 0.01); in Group 2 it was 3 months in medical patients as compared with 12 months in surgical patients (P = 0.04). The median duration of hospitalization was longer in medical patients than in surgical patients (6.1 vs. 2.4 weeks in Group 1 [P less than 0.001] and 5.0 vs. 3.1 weeks in Group 2 [P less than 0.01]). Group 3 was too small to permit a meaningful comparison. During the initial hospitalization, the incidence of infections, gastrointestinal bleeding, and encephalopathy was similar among the medical and surgical patients. We conclude that peritoneovenous shunting alleviated disabling ascites more rapidly than medical management. However, survival was closely related to the severity of the illness at the time of randomization and was not altered by shunting.

Deterioration in nutritional parameters is a significant risk factor for survival in severe patients with alcoholic hepatitis. This deterioration is reversible with standard hospital care. Active therapy further improves creatinine height index, mid arm muscle area and total lymphocyte counts. Hence, these later parameters appear to be the best indicators for follow-up assessments.

Seven clinically healthy, nondiabetic (ND) and four Type II diabetic (D) men were assessed for circadian rhythms in oxidative "stress markers." Blood samples were collected at 3h intervals for approximately 27 h beginning at 19:00h. Urine samples were collected every 3 h beginning with the 16:00h-19:00h sample. The dark (sleep) phase of the light-dark cycle extended from 22:30h to 06:30h, with brief awakening for sampling at 01:00h and 04:00h. Subjects were offered general hospital meals at 16:30h, 07:30h, and 13:30h (2400 cal in total/24h). Serum samples were analyzed for uric acid (UA) and nitrite (NO) concentrations, and urine samples were assayed for 8-hydroxydeoxyguanosine (8-OHdG), malondialdehyde (MDA), and 8-isoprostane (ISP). Data were analyzed statistically both by the population multiple-components method and by the analysis of variance (ANOVA). The 24h mean level of UA and NO was greater in D than in ND subjects (424 vs. 338 micromol/L and 39.2 vs. 12.7 microM, respectively). A significant circadian rhythm in UA (p = 0.001) and NO (p = 0.048) was evident in ND but not in D (p = 0.214 and 0.065). A circadian rhythm (p = 0.004, amplitude = 8.6 pmol/kgbw/3h urine vol.) was also evident in urine 8-OHdG of ND but not of D. The 24h mean levels of ND and D were comparable (76.8 vs. 65.7 pmol/kgbw/3h urine vol.). No circadian rhythm by population multiple-components was evident in MDA and ISP levels of ND subjects, or in 8-OHdG, MDA, and ISP in D. However, a significant time-effect was demonstrated by ANOVA in all variables and groups. The 24h mean of MDA and ISP in D was significantly greater than in ND (214 vs. 119 nmol/3h urine vol. and 622 vs. 465 ng/3h urine vol.). The peak concentrations of the three oxidative "stress markers" in urine, like those of serum NO, occurred early in the evening in both groups of men. This observation suggests a correlation between increased oxidative damage and increased rate of anabolic-catabolic events as evidenced by similarities in the timing of peak NO production and in parameters relevant to metabolic functions.
