Treatment of Sleep Disturbances and Appetite Stimulation

Pharmacological Interventions

• The National Comprehensive Cancer Network recommends mirtazapine doses of 7.5-30 mg for sleep disturbances, and 15-30 mg daily for appetite stimulation and anxiety symptoms 1, 2, 3, 4, 5
• Megestrol acetate is the most effective medication for increasing appetite, with high-quality evidence showing significant appetite stimulation and weight gain, though it carries risks that must be monitored, according to the Clinical Nutrition guideline and the American College of Physicians 6, 7, 5
• Dexamethasone provides rapid appetite stimulation, but its use is recommended for short-term only (1-3 weeks) due to side effects such as muscle wasting, insulin resistance, and increased infection risk, as stated by the Clinical Nutrition guideline and other authorities 6, 2, 1
• Cyproheptadine is a well-established safety profile and effective appetite stimulant, especially in pediatric patients, with a recommended dosage of 2-4 mg three times daily 1, 5
• Olanzapine (5 mg/day) is an alternative option with fewer thromboembolic risks, but requires monitoring for metabolic side effects 1

Non-Pharmacological Interventions

• Providing energy-dense and protein-rich foods can help decrease food volume while increasing nutritional content, as suggested by Clinical Nutrition guidelines 8
• Oral nutritional supplements (ONS) should be offered to elderly persons with malnutrition or at risk of malnutrition to improve dietary intake and body weight, with a recommendation of at least 400 kcal/day including 30g or more of protein/day, according to Clinical Nutrition guidelines 9
• Implementing non-pharmacological approaches, such as small, frequent meals, high-calorie, nutrient-dense foods, creating a pleasant eating environment, and moderate physical activity, can be beneficial when used alongside medication for best results 2, 6, 10, 11, 12, 13
• Promoting shared meals and social eating opportunities can be beneficial, as recommended by Clinical Nutrition guidelines 11
• Providing adequate mealtime assistance for those with functional limitations is important, according to Clinical Nutrition guidelines 11
• Implementing protected mealtimes in institutional settings can create a conducive eating environment, as suggested by Clinical Nutrition guidelines 8

Nutrition Recommendations

• Protein intake recommendations for elderly patients include 1.0-1.2 g/kg/day for healthy elderly, 1.2-1.5 g/kg/day for those with acute or chronic diseases, and >1.5 g/kg/day for those with cachexia or sarcopenia, as recommended by 14
• Meals on wheels for home-dwelling elderly should be energy-dense and/or include additional meals, as suggested by Clinical Nutrition guidelines 11
• Consideration should be given to enhanced meal delivery programs that provide three meals and snacks daily, according to Clinical Nutrition guidelines 11

Physical Activity and Exercise

• Encouraging physical activity and exercise alongside nutritional interventions can help maintain or improve muscle mass and function, as recommended by Clinical Nutrition guidelines 11
• Evaluating health status and physical performance level before starting exercise interventions is crucial, according to Clinical Nutrition guidelines 11
• Moderate physical activity, such as supervised or home-based moderate-intensity training, can naturally stimulate appetite in pediatric and elderly patients, as recommended by the American Academy of Pediatrics and the American College of Nutrition 6

Monitoring and Evaluation

• Monitoring should include weight changes, appetite improvement, anxiety symptoms, and side effects such as sedation, dry mouth, and dizziness, with caution advised when combining with other CNS depressants 15
• Regular follow-up evaluations should include reassessing appetite and weight after 2-4 weeks of therapy, as well as monitoring for medication-specific side effects such as somnolence, dizziness, fluid retention, and thromboembolic events 2, 3, 4, 11, 16
• The American Academy of Nutrition and Dietetics suggests that monitoring weight changes is essential to assess the effectiveness of appetite stimulants, with weight gain of >7% body weight requiring evaluation of benefit vs. risk 2
• Using validated screening tools, such as the Mini Nutritional Assessment (MNA), can help identify nutritional risk in elderly patients, with scores ≤11 indicating possible malnutrition and requiring further assessment, as recommended by the American Geriatrics Society 17

Benefit/Risk Assessment

Treatment Approach

• A step-wise approach to appetite stimulation is recommended, starting with comprehensive non-pharmacological approaches for 2-4 weeks, followed by initiation of cyproheptadine if insufficient response, and consideration of alternative options if no response to cyproheptadine after 4 weeks, as recommended by the American College of Nutrition and the National Comprehensive Cancer Network 6, 1
• The American Academy of Sleep Medicine recommends considering cyproheptadine for appetite stimulation and mild anxiolytic effects, given its mechanism of action and clinical evidence 15
• A step-ladder approach is proposed, starting with cyproheptadine 4mg at night, monitoring for appetite improvement, weight gain, and anxiety relief, and assessing for side effects, with potential escalation to higher doses or addition of clonazepam if inadequate response 15
