Two doses of megestrol acetate (MA) have been prospectively compared in a random fashion as treatment for cancer-related anorexia-cachexia syndrome (ACS) in 122 patients with progressive soft tissue sarcoma, colorectal, lung, head and neck and renal cancer resistant to systemic chemotherapy. After 30 days of MA, 55% of patients receiving MA at 160 mg day-1 reported an increase in appetite, 27% of patients no variation and 18% complained of a decrease in appetite. Patients treated with MA at 320 mg day-1 reported an increase in appetite in 68% of cases, a stabilisation in 20% of cases and a decrease in 12%. Although an increase in appetite was more frequently observed in patients receiving MA at 320 mg day-1, however this difference was not statistically significant (P = 0.305). After 30 days of MA, 31% of patients treated with MA at 160 mg day-1 showed an increase in body weight, 25% a stabilisation and 44% a decrease. In the group of patients treated with MA at 320 mg day-1, 45% reported an increase in body weight, 16% no change and 23% weight loss. Although there was a trend favouring the higher dose of MA, overall analysis however failed to detect any statistically significant difference between the two treatment arms (P = 0.242). Twenty-seven patients pretreated with 160 mg day-1 and 23 patients treated with 320 mg day-1 received further therapy with MA at the dose of 320 and 480 mg day-1 respectively. In the group of 22 patients treated with 320 mg day-1 four (18%) reported an increase in body weight, eight (36%) an improvement in appetite, but none had an increase in performance status. Among the 20 evaluable patients treated with 480 mg day-1, two (10%) had an increase in body weight, four (20%) an improvement in appetite, but none reported an increase in performance status. No difference in median survival was detected between the two arms. Toxicity was mild and predictable. In conclusion, the data achieved in the present study confirm the clinical safety and effectiveness of oral MA in the management of ACS in patients with advanced cancer resistant to systemic chemotherapy. Moreover, data concerning the dose escalation of MA dosage in unresponsive patients suggest that a step by step increase in MA dosage could be the best way of administering MA for the management of ACS and that the increase of MA dosage over 480 mg day-1 will probably be useless in the vast majority of cases. Data on body weight suggest that after 2 weeks' therapy MA could be stopped or its dosage tailored to patients' needs since the majority of patients respond after only 15 days of MA. To assess the effect of megestrol acetate (MA), a progestational appetite stimulant commonly used in patients with AIDS and cancer, on body weight and composition, respiratory muscle strength, arterial blood gas levels, and subjective perceptions in COPD patients.
                Prospective, double-blind, randomized, placebo-controlled trial conducted on an outpatient basis at 18 sites.
                Underweight (< 95% ideal body weight) COPD patients > or = 40 years old.
                Either MA, 800 mg/d oral suspension, or placebo at a 1:1 ratio for 8 weeks.
                Of 145 randomized patients (63% men), 128 patients completed the trial. Body weight increased by 3.2 kg in the MA group and 0.7 kg in the placebo group (p < 0.001). Anthropometric and dual-energy radiograph absorptiometry assessments confirmed that weight gain was mainly fat. Spirometry and maximal voluntary ventilation showed no significant changes from baseline in either group, and the difference in the change in maximum inspiratory pressure between groups was not significant. The 6-min walk distances did not differ statistically between groups at week 2 and week 4, but were greater in the placebo group at week 8 (p = 0.012). Consistent with the known ability of MA to stimulate ventilation, PaCO(2) decreased (4.6 mm Hg, p < 0.001) and PaO(2) increased (2.8 mm Hg, p < 0.04) in the MA group. Questionnaires revealed that body image and appetite improved in the MA group but not the placebo group. Adverse event frequency and type were similar in both groups, but cortisol and testosterone (in men) levels decreased substantially in the MA group.
                We conclude that MA safely increased appetite and body weight, stimulated ventilation, and improved body image in underweight COPD patients, but did not improve respiratory muscle function or exercise tolerance. Studies suggest eicosapentaenoic acid (EPA), an omega-3 fatty acid, augments weight, appetite, and survival in cancer-associated wasting. This study determined whether an EPA supplement-administered alone or with megestrol acetate (MA)-was more effective than MA.
                Four hundred twenty-one assessable patients with cancer-associated wasting were randomly assigned to an EPA supplement 1.09 g administered bid plus placebo; MA liquid suspension 600 mg/d plus an isocaloric, isonitrogenous supplement administered twice a day; or both. Eligible patients reported a 5-lb, 2-month weight loss and/or intake of less than 20 calories/kg/d.
                A smaller percentage taking the EPA supplement gained >or= 10% of baseline weight compared with those taking MA: 6% v 18%, respectively (P =.004). Combination therapy resulted in weight gain of >or= 10% in 11% of patients (P =.17 across all arms). The percentage of patients with appetite improvement (North Central Cancer Treatment Group Questionnaire) was not statistically different: 63%, 69%, and 66%, in EPA-, MA-, and combination-treated arms, respectively (P =.69). In contrast, 4-week Functional Assessment of Anorexia/Cachexia Therapy scores suggested MA-containing arms experienced superior appetite stimulation compared with the EPA arm, with scores of 40, 55, and 55 in EPA-, MA-, and combination-treated arms, respectively (P =.004). Survival was not significantly different among arms. Global quality of life was not significantly different among groups. With the exception of increased impotence in MA-treated patients, toxicity was comparable.
                This EPA supplement, either alone or in combination with MA, does not improve weight or appetite better than MA alone. The aim of this review is to assess the efficacy and safety of megestrol acetate (MA) in geriatric cachexia. The paper presented here reviews a previously published study of MA use in 69 patients in a randomized double blind placebo-controlled trial. This paper will also address the underlying pathogenesis of cachexia (specifically, the role of cytokines) along with the use of MA, its mechanism of action and its side effects.
                To compare the effects of MA oral suspension (O.S.), 800 mg/day, versus placebo on weight in geriatric nursing home patients with weight loss or low body weight.
                Twelve weeks, randomized, double-blind, placebo-controlled trial with a 13-week follow-up period.
                Northport VAMC Nursing home patients with weight loss of * 5% of usual body weight over the past 3 months, or body weight 20% below their ideal body weight.
                Patients were randomly assigned to receive placebo or MA 800 mg/d for 12 weeks and were then followed for 13 weeks off treatment and mortality 4 years post treatment.
                Primary outcome- weight and appetite change. Secondary outcome-sense of well being, enjoyment of life, change in depression scale, laboratory nutrition parameters, energy intake counts, body composition, and adverse events.
                At 12 weeks there were no significant differences in weight gain between treatment groups, while MA-treated patients reported significantly greater improvement in appetite, enjoyment of life, and well being. At week 25 (3 months after treatment), 61.9% of MA-treated patients had gained * 1.82 kg (4 lbs) compared to 21.7% of placebo patients. There was no difference in survival between MA and placebo groups. Considering possible confounders, higher initial IL-6, initial TNFR-p75 levels, and final neutrophil percentage were associated with elevated mortality, whereas higher initial pre-albumin, initial albumin, final pre-albumin, final albumin and final weight gain were associated with decreased death. To assess the effect of megestrol acetate (MA) on the appetite and weight of cancer patients with nonhormone-dependent tumors, a double-blind, placebo-controlled trial was designed. One hundred fifty patients were included: 76 were given MA (240 mg/day orally) for at least 2 months, and 74 were given placebo (P). Body weight, subjective sense of appetite (SSA) evaluated by an analogic linear visual scale scored from 1 to 10, and performance status (PS) were measured before therapy and monthly thereafter. No differences in body weight before and after treatment could be found in any group. However, 32% of the patients in the MA group (95% confidence interval: 20.1-44.6%) gained 2 or more kilograms (P less than 0.001). This group also showed an improvement in SSA (P less than 0.01): an increase greater than or equal to 2 points appeared in 57.5% of patients (95% confidence interval 44.6-69.4%). There was no significant difference in PS for the treatment groups before or after therapy. The percentage of reported adverse events did not differ significantly from one treatment group to the next. We conclude that therapy with MA at a dose of 240 mg/day improved SSA and was associated with moderate weight gain in patients with hormone-insensitive malignancies. The aim of this study was to evaluate a low-dose regimen of megestrol acetate (MA; 320 mg/day) on appetite in advanced cancer patients. Out-patients with far-advanced non-hormone responsive tumours and loss of appetite were randomised in a phase III trial, with two consecutive phases: a 14-day double-blind placebo controlled phase (phase A) and a 76-day open phase (phase B). During phase A, patients were treated with MA, two 160 mg tablets/day, or placebo. In phase B, the MA dose was titrated to clinical response in both groups. Appetite, food intake, body weight, performance status, mood and quality of life were evaluated with standardised measures; patients' global judgement about treatment efficacy was also requested. Of 42 patients entering the study, 33 (17 MA and 16 placebo) were evaluable for efficacy. The appetite score improved significantly with MA after 7 days (P = 0.0023), and this effect was still significant at 14 days (P = 0.0064). Patients judged the treatment with MA effective in 88.2% of cases (14th day), whilst placebo was considered effective by 25% (P = 0.0003). None of the other measures showed significant changes during treatment. The remarkable effect on appetite evident after 7 days, without serious side-effects, shows that MA can produce significant subjective effects at a low-dose even in patients with far-advanced disease. A randomised double-blind placebo-controlled multicentre trial was performed to investigate the effects of megestrol acetate (MA) on the quality of life (QoL), appetite, weight and survival of patients with advanced, incurable, hormone-insensitive cancer. QoL was assessed at the start of treatment and at 4, 8 and 12 weeks, using the EORTC-QLQ-C30 instrument. 255 patients were randomised to 320 mg of MA daily or placebo for 12 weeks. 244 patients were assessable at baseline, 190 at 4 weeks (placebo 94; MA 96), 150 at 8 weeks (placebo 69; MA 81) and 112 at 12 weeks (placebo 55; MA 57). A beneficial effect of MA on appetite loss was observed at week 4 (P < 0.0001) and possibly at week 8 (P = 0.058). Further weight loss during treatment was significant only in the placebo group. In the first 8 weeks, changes in mean global QoL were small and similar in both groups. By 12 weeks the decrease in mean global QoL was more pronounced in the MA group (P = 0.028), which was related to a deterioration in physical function, while psychosocial function was not affected. Survival was not affected by MA, and side-effects were mild. The results show that MA has a beneficial effect on appetite and that it may retard weight loss with no adverse impact on survival and with mild toxicity. However, MA does not appear to improve global QoL as measured by the EORTC QLQ-C30. Preliminary information has suggested that megestrol acetate leads to appetite stimulation and nonfluid weight gain in patients with breast cancer, other cancers, and AIDS. Pursuant to this, we developed a randomized, double-blind, placebo-controlled trial of megestrol acetate in patients with cancer-associated anorexia and cachexia. We randomly assigned 133 eligible patients to receive 800 mg of megestrol acetate per day or a placebo. Patients assigned to megestrol acetate more frequently reported improved appetite (P = .003) and food intake (P = .009) when compared with patients receiving the placebo. A weight gain of 15 lb or more over baseline was seen in 11 of 67 (16%) patients receiving megestrol acetate compared with one of 66 (2%) given the placebo (P = .003). Patients receiving megestrol acetate reported significantly less nausea (13% vs. 38%; P = .001) and emesis (8% vs. 25%, P = .009). No clinically or statistically significant toxic reactions were ascribed to megestrol acetate, with the exception of mild edema. This study convincingly demonstrated that megestrol acetate can stimulate appetite and food intake in patients with anorexia and cachexia associated with cancer, leading to significant weight gain in a proportion of such patients. To compare the effects of oral suspensions of megestrol acetate, 800 mg/d, and placebo on body weight in patients with acquired immunodeficiency syndrome (AIDS)-related weight loss.
                Randomized, double-blind, placebo-controlled trial.
                Outpatient community and university patient care setting.
                Consecutive patients with AIDS who had substantial weight loss and anorexia were enrolled. Of 271 patients, 270 and 195 were evaluable for safety and efficacy, respectively.
                Patients were randomly assigned to receive placebo or megestrol acetate (100 mg, 400 mg, or 800 mg) daily for 12 weeks.
                The primary efficacy criterion was weight gain. Patients were evaluated at 4-week intervals for changes in weight and body composition, caloric intake, sense of well-being, toxic effects, and appetite.
                For evaluable patients receiving 800 mg of megestrol acetate per day, 64.2% gained 2.27 kg (5 pounds) or more compared with 21.4% of patients receiving placebo (P < 0.001). An intent-to-treat analysis showed significant differences (P = 0.002) between those receiving placebo and those receiving 800 mg of megestrol acetate for the number of patients who gained 2.27 kg (5 pounds) or more (8 of 32 [25%] compared with 38 of 61 [62.3%], respectively). Compared with patients receiving placebo at the time of maximum weight change, evaluable patients receiving megestrol acetate, 800 mg/d, reported improvement in overall well-being and had an increase in mean weight gain (-0.725 compared with 3.54 kg [-1.6 compared with +7.8 pounds]; P < 0.001), lean body mass (-0.772 compared with +1.14 kg [-1.7 compared with +2.5 pounds]; P < 0.001), appetite grade (P < 0.001), and caloric intake (-107 compared with +645.6 calories/d; P = 0.001).
                In patients with AIDS-related weight loss, megestrol acetate can stimulate appetite, food intake, and statistically significant weight gain that is associated with a patient-reported improvement in an overall sense of well-being. This double-blind, cross-over trial was designed to assess the effects of megestrol acetate (MA) on cancer-induced cachexia. Forty consecutive malnourished patients with advanced non-hormone-responsive tumors receiving no antineoplastic treatment were randomized to receive MA 480 mg/day versus placebo for 7 days. During day 8, a cross-over was made until day 15. Appetite, pain, nausea, depression, energy, and well-being were assessed with a visual analog scale (0 to 100 mm) at 9:00 AM and 4:00 PM during days 6, 7, 13, and 14. Weight (W;kg), tricep skinfold (TS; mm), arm circumference (AC; cm), and calf circumference (CC; cm) were measured at days 1, 8, and 15. Caloric intake (CI; Kcal/day) was determined during days 6, 7, 13, and 14. In 31 evaluable patients, the percentual difference in appetite at 9:00 AM, appetite at 4:00 PM, energy, and well-being after MA was +15.1, +14, +3.2, and +5.2, versus -12 (P = 0.03), -5.1 (P = 0.015), -10 (P = 0.024), and -8.3 (not significant) after placebo. Percentual difference in W, TS, AC, and CC after MA was +0.2, +1, -0.1, and +0.4 versus -0.8 (P = 0.03), -0.8 (P = 0.001), -0.3 (not significant), and -0.5 (P = 0.04) after placebo. CI during MA was 3480 +/- 1574 (48-hour intake), versus 2793 +/- 1542 (P less than 0.001) during placebo. Patients and investigators blindly chose MA in 20 (66%, P = 0.023) and 28 cases (92%, P less than 0.001), placebo in eight and two cases, and made no choice in three and one cases, respectively. Toxicity consisted of mild edema and nausea in three and two cases, respectively. After mean follow-up of 27 +/- 13 days, on an open basis, an average increase in W and AC of 4.8 +/- 1.7 kg and 2.8 +/- 1.7 cm was observed, respectively. The authors conclude that MA is a powerful appetite stimulant with subjective and objective effects on nutritional status. To investigate the effects of medroxyprogesterone acetate (MPA) on appetite, weight, and quality of life (QL) in patients with advanced-stage, incurable, non-hormone-sensitive cancer.
                Two hundred six eligible patients were randomized between double-blind MPA 500 mg twice daily or placebo. Appetite (0 to 10 numerical rating scale), weight, and QL (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire [EORTC-QLQ-C30]) were assessed before the start of treatment (t = 0), and 6 weeks (t = 6) and 12 weeks (t = 12) thereafter.
                One hundred thirty-four patients (68 MPA and 66 placebo) were assessable at t = 6 and 99 patients (53 MPA and 46 placebo) at t = 12. A beneficial effect of MPA on appetite was observed after both 6 weeks (P = .008) and 12 weeks (P = .01) of treatment. After 12 weeks, a mean weight gain of 0.6 +/- 4.4 kg was seen in the MPA, versus an ongoing mean weight loss of 1.4 +/- 4.6 kg in the placebo group. This difference of 2.0 kg was statistically significant (P = .04). During the study, several areas of QL deteriorated in the total group of patients. With the exception of an improvement in appetite and possible also a reduction in nausea and vomiting, no measurable beneficial effects of MPA on QL could be demonstrated. The side effects profile of MPA was favorable: only a trend toward an increase in (usually mild) peripheral edema was observed.
                In weight-losing, advanced-stage non-hormone-sensitive cancer patients, MPA exhibits a mild side effects profile, has a beneficial effect on appetite, and may prevent further weight loss. However, general QL in the present study was not measurably influenced by MPA treatment. High-dose megestrol acetate has been associated with increased appetite and weight. To examine the effects of high-dose megestrol acetate in the treatment of anorexia and weight loss in patients with advanced hormone-insensitive malignant lesions, a randomized double-blind placebo-controlled trial was conducted. Patients receiving megestrol acetate for 1 month reported a significant improvement in appetite and adequacy of food intake compared with those receiving placebo. A three-item scale measuring appetite, adequacy of food intake, and concern about weight revealed a higher improvement with megestrol acetate than with placebo. Patients who worsened while receiving placebo had similar favorable changes after the cross over to megestrol acetate. These data indicate that megestrol acetate may improve appetite and food intake in patients with advanced cancer. To determine whether dronabinol administered alone or with megestrol acetate was more, less, or equal in efficacy to single-agent megestrol acetate for palliating cancer-associated anorexia.
                Four hundred sixty-nine assessable advanced cancer patients were randomized to (1) oral megestrol acetate 800 mg/d liquid suspension plus placebo, (2) oral dronabinol 2.5 mg twice a day plus placebo, or (3) both agents. Eligible patients acknowledged that loss of appetite or weight was a problem and reported the loss of 5 pounds or more during 2 months and/or a daily intake of less than 20 calories/kg of body weight.
                Groups were comparable at baseline in age, sex, tumor type, weight loss, and performance status. A greater percentage of megestrol acetate-treated patients reported appetite improvement and weight gain compared with dronabinol-treated patients: 75% versus 49% (P =.0001) for appetite and 11% versus 3% (P =.02) for > or = 10% baseline weight gain. Combination treatment resulted in no significant differences in appetite or weight compared with megestrol acetate alone. The Functional Assessment of Anorexia/Cachexia Therapy questionnaire, which emphasizes anorexia-related questions, demonstrated an improvement in quality of life (QOL) among megestrol acetate-treated and combination-treated patients. The single-item Uniscale, a global QOL instrument, found comparable scores. Toxicity was also comparable, with the exception of an increased incidence of impotence among men who received megestrol acetate.
                In the doses and schedules we studied, megestrol acetate provided superior anorexia palliation among advanced cancer patients compared with dronabinol alone. Combination therapy did not appear to confer additional benefit. Two appetite stimulants, megestrol acetate and cyproheptadine were administered in a randomized trial to 14 patients who had no evidence of opportunistic infection or malabsorption but were wasted (had lost more than 5 kg body weight) as a result of human immunodeficiency virus (HIV) infection. Energy intakes were calculated from a 7 day weighed dietary record. Mean energy intakes per kilogramme body weight were similar in both treatment groups (greater than 34 kcal/kg) and were higher than that in well British males. Energy intakes increased by just over 500 kcal during both treatments, but fell to pretreatment levels after therapy. Patients in both treatment groups gained a moderate amount of weight. Megestrol acetate was associated with impotence in 4 patients. Insufficient calorie intake alone is not a common cause of wasting associated with HIV and the role of appetite stimulants is likely to be limited. To study the effects of a megestrol acetate liquid formulation (800 mg/d) on body weight, body composition, caloric intake, and mental outlook in patients with the acquired immunodeficiency syndrome (AIDS) who had cachexia.
                Twelve-week, multicenter, randomized, double-blind, placebo-controlled trial.
                Multiple clinical centers.
                100 patients with AIDS who had weight loss of 10% or more of ideal body weight were randomly assigned to placebo (n = 48) or megestrol acetate (n = 52).
                Caloric intake, body weight, body composition, and sense of well-being.
                Most patients receiving megestrol acetate had increased caloric intake resulting in body weight gain (mainly fat mass). From baseline to week 8, the megestrol acetate group increased their daily caloric intake by 608 calories, whereas the placebo group increased intake by 134 calories (difference, 474 calories; 95% CI, -68 to 880 calories). Body weight in the megestrol acetate group increased by 3.86 kg from baseline to week 8, although it decreased by 0.46 kg in the placebo group (difference, 4.32 kg; CI, 2.42 to 6.22 kg). At week 8 in the megestrol acetate group, patients gained 3.68 kg in fat mass and those in the placebo group lost 0.28 kg (difference, 3.96 kg; CI, 2.49 to 5.43 kg). Body water, lean mass, and patient survival were not statistically different between treatment groups. Patients treated with megestrol acetate had an increased sense of well-being when compared with patients who received placebo.
                This megestrol acetate liquid formulation is well tolerated, increases food intake, results in body weight gain, and improves the sense of well-being in cachectic patients with AIDS. A placebo-controlled, randomized trial assessed the activity, tolerance, and degree of weight gain and anorexia of two doses of megestrol acetate in patients with advanced cancer and cachexia. Patients received either low-dose (480 mg/day) or high-dose (960 mg/day) megestrol acetate or placebo for 8 weeks. As of March 1991, 91 patients had been randomized; 65 patients were evaluable. Median initial weight loss in all patients ranged from 13 to 16%. Further weight loss was seen in 13 of 17 patients in the placebo group, compared with 10 of 27 and 6 of 21 in the low- and high-dose megestrol acetate groups, respectively. Eight of 27 patients in the low-dose-group and 9 of 21 in the high-dose group gained weight, with a median of 3 and 4 kg, respectively. Beneficial effects of megestrol acetate were seen in 63 and 71% of the low- and high-dose groups, respectively, compared with 24% of the placebo group. Side effects of megestrol acetate were mild. No correlation between megestrol acetate dosage and weight gain was found, but there was a tendency for increased weight in more patients taking high-dose megestrol acetate. Megestrol acetate, a semisynthetic gestagen, is effective not only for endocrine therapy of advanced breast carcinomas, but also in the treatment of cachectic patients with aggressive, hormone-independent tumors. Sixty-six patients with therapy-resistant, advanced bronchogenic carcinomas of different histologic types, who had lost more than 10% of their regular body weight within a prospective, randomized trial, were treated with megestrol acetate at a dose of either 160 or 480 mg/day for 3-4 months. The mean weight gain for all patients was 2.5 kg. Nearly all of them (80%) reported improved appetite and well-being. The mean weight gain in the group of patients receiving 480 mg/day was higher (3.0 kg) than in the group receiving 160 mg/day (2.0 kg). To investigate the effect of two doses of megestrol acetate (MA) compared with placebo on quality of life (QoL) and nutritional status (NS) in patients with advanced endocrine-insensitive cancer.
                Two hundred forty patients were randomised to double-blind MA 480 mg/day, MA 160 mg/day, or matching placebo for 12 weeks. Nutritional status (including weight, skinfold thickness and midarm circumference) and QoL (using 6 linear analogue self-assessment (LASA) scales) were assessed at randomisation and after four, eight and 12 weeks. A QoL ranking incorporating QoL and death was also used ranging from 1 = dead to 5 = much better QoL.
                One hundred seventy-four patients were assessable at week four, 136 at week eight and 103 patients at week 12. Patients receiving MA reported substantially better appetite (P = 0.001), mood (P = 0.001) and overall quality of life (P < 0.001), and possibly less nausea and vomiting (P = 0.08) than patients receiving placebo, based on a test for trend. A larger benefit was seen with the higher dose which (unlike the lower dose) was significantly better in pairwise comparisons with placebo for appetite, mood and overall QoL (each P < or = 0.001). Despite some missing data on QoL scores, QoL ranking was available on 227 (95%) of patients with significantly higher QoL ranking associated with MA (P = 0.002). Improvements in QoL occurred early within four weeks and were sustained. No statistically significant differences were observed in NS measurements, including weight (P = 0.29). Side effects of therapy were minor and did not differ significantly across treatments.
                Megestrol acetate given at 480 mg/day is useful palliation in patients with endocrine-insensitive advanced cancer. It improves appetite, mood and overall quality of life in these patients, although not through a direct effect on nutritional status. To evaluate the effects of nutrition counseling with or without oral supplementation in malnourished patients infected with the human immunodeficiency virus (HIV).
                Randomized controlled trial.
                HIV-infected men (n=118) who were less than 90% of usual weight for height or who had lost more than 10% of body weight.
                Nutrition counseling alone (control group) vs nutrition counseling plus enteral supplementation (supplement group) for 6 weeks. All patients were instructed to consume a diet that exceeded estimated total energy expenditure by 960 kcal/day.
                Weight, skinfold thickness, fat-free mass, grip strength, quality of life, and cognitive function (Buschke test).
                Differences in baseline variables and outcomes were evaluated using analysis of variance or the Wilcoxon rank sum test.
                Ninety-nine men completed at least 4 weeks of treatment, 49 in the supplement group and 50 in the control group. Half the patients in each treatment group achieved at least 80% of their energy target. No differences in weight, skinfold thickness measurements, or quality of life were observed. Compared with the control group, the supplement group had larger increases in fat-free mass and grip strength, although the differences did not reach statistical significance.
                In the short term, nutrition counseling with or without oral supplementation can achieve a substantial increase in energy intake in about 50% of malnourished HIV-infected patients. Although further study is needed to evaluate long-term effects, these findings suggest that nutrition counseling has an important role in the management of malnourished HIV-infected patients. This double-blind controlled study examines the impact of clomipramine when taken by an anorexia nervosa population, refeeding in hospital, over and above that generated by the established treatment programme. Of the 16 patients studied, all reached their target weights including three who asked to leave the study. Clomipramine was significantly associated with increased hunger, appetite and energy intake. It tended, though, to be associated with a reduced rate of weight gain, possibly because activity was increased. Patients receiving clomipramine were more stable in their eating habits and maintained body weight better than those on placebo after leaving the trial. These findings indicate the sensitivity of the hypothalamus to changes in body weight. Clomipramine, which is known to act at a hypothalamic level, seems to influence hunger, appetite and dietary intake according to the body weight of the patient. The threshold weights which have been shown to trigger hypothalamic sexual responses, may also influence hunger, appetite, motility and voluntary energy intake. A Nordic multicenter study in asymptomatic patients with advanced colorectal cancer compared initial chemotherapy with sequential methotrexate-5-FU with leucovorin rescue (MFL) for 6 months versus primary expectancy with chemotherapy only after the appearance of symptoms. The study (183 patients randomized between January 1985 and February 1990) showed that symptom-free survival, progression-free survival and survival respectively were about 6 months longer in the group of patients randomized to initial MFL. Whether these prolongations could be achieved without an impaired 'quality of life' was studied in an associated study. Between January 1985 and March 1987, 43 patients were randomized at one of the hospitals, 36 of which were interviewed with a questionnaire at randomization. Even if all these patients were considered, by the physician, to be 'free of symptoms from their disease', 16/36 (44%) had symptoms that could be referred to the disease. In spite of this, the patients were in a good general condition, and considerably better off than patients considered to have 'symptoms from the disease' who were interviewed with the same questionnaire when randomized in a parallel study of symptomatic patients. Patients randomized to initial chemotherapy and interviewed longitudinally maintained their good condition throughout treatment. Toxicity was mild, although the patients expressed more adverse effects than the physicians recorded. Since symptom-free survival, progression-free survival and survival were statistically significantly longer in the group of patients randomized to MFL also in this associated study, it is concluded that initial chemotherapy can prolong symptom-free survival and survival without reduced 'quality of life' during the treatment period. To compare nutritional counseling with and without oral supplements in HIV-infected patients with recent weight loss.
                Randomized non-blinded controlled trial, stratified for change in antiretroviral treatment at baseline.
                HIV-infected patients with recent weight loss (> 5% of total, and >3% in the last month).
                Nutritional counseling to increase dietary intake by 600 kcal/day over 8 weeks; in group A (n=24) by normal food, and in group B (n=26) by a range of fortified drink supplements with a calorific value of 0.6 to 1.5 kcal/ml.
                Body composition by bioelectrical impedance analysis, dietary intake by 24 h recall.
                Fat free mass increased from baseline to week 8 (P<0.05) with no difference between groups A and B (P=0.97). Body cell mass and weight gain were not significant and equal between groups. Assessed at weeks 2 and 4, group B patients consumed 11 +/- 6 kcal/kg as supplements, and their total energy intake was 6 kcal/kg higher than in group A (P<0.01). Total energy intake was not different between groups at weeks 6 and 8.
                Nutritional counseling and oral supplements are both feasible methods to restore food energy intake in malnourished HIV-infected patients. Although normal food intake is partially replaced, oral supplements may improve the adherence to a weight gain regimen.
                Copyright 1999 Harcourt Publishers Ltd. A phase III, randomized study was carried out to establish the most effective and safest treatment to improve the primary endpoints of cancer cachexia-lean body mass (LBM), resting energy expenditure (REE), and fatigue-and relevant secondary endpoints: appetite, quality of life, grip strength, Glasgow Prognostic Score (GPS) and proinflammatory cytokines.
                Three hundred thirty-two assessable patients with cancer-related anorexia/cachexia syndrome were randomly assigned to one of five treatment arms: arm 1, medroxyprogesterone (500 mg/day) or megestrol acetate (320 mg/day); arm 2, oral supplementation with eicosapentaenoic acid; arm 3, L-carnitine (4 g/day); arm 4, thalidomide (200 mg/day); and arm 5, a combination of the above. Treatment duration was 4 months.
                Analysis of variance showed a significant difference between treatment arms. A post hoc analysis showed the superiority of arm 5 over the others for all primary endpoints. An analysis of changes from baseline showed that LBM (by dual-energy X-ray absorptiometry and by L3 computed tomography) significantly increased in arm 5. REE decreased significantly and fatigue improved significantly in arm 5. Appetite increased significantly in arm 5; interleukin (IL)-6 decreased significantly in arm 5 and arm 4; GPS and Eastern Cooperative Oncology Group performance status (ECOG PS) score decreased significantly in arm 5, arm 4, and arm 3. Toxicity was quite negligible, and was comparable between arms.
                The most effective treatment in terms of all three primary efficacy endpoints and the secondary endpoints appetite, IL-6, GPS, and ECOG PS score was the combination regimen that included all selected agents. This randomized, controlled trial assessed the activity, tolerance, and degree of weight gain and anorexia of two doses of megestrol acetate in patients with advanced cancer and cachexia. Patients received either 480 mg/d or 960 mg/d megestrol acetate or placebo for 8 weeks. As of June 1990, 55 patients had been randomized; 16 died during the 8-week study, and it was too early to evaluate another 5 patients. The remaining 34 patients were included in analyses. The median initial weight loss ranged from 15% to 22% of usual body weight, which shows the severe degree of malnutrition. Further weight loss was seen in 6 of 8 patients in the placebo group compared with only 5 of 15 and 3 of 11 patients in the low-dose and high-dose megestrol acetate groups, respectively. The median further weight loss was comparable in all groups. Six of 15 and 6 of 11 patients in the low-dose and high-dose groups, respectively, gained weight with a median of 3 kg and 4 kg, respectively. A trend showed beneficial effects of megestrol acetate. Appetite improvement was similar in all groups. Due to the small sample size, however, there were no statistically significant differences among the three groups. Side effects of megestrol acetate were mild. In a subgroup of 15 patients, measurement of body water content indicated a decrease of body fat after 8 weeks in the placebo and low-dose groups. Only the high-dose megestrol acetate group showed an increase in both fat and lean body mass, suggesting a positive effect.
This review shows that MA improves appetite and is associated with slight weight gain in cancer, AIDS and in patients with other underlying pathology. Despite the fact that these patients are receiving palliative care they should be informed of the risks involved in taking MA.
