RESUMO

Leptin is an appetite-regulating adipokine that is reduced in patients with anorexia nervosa (AN), a psychiatric disorder characterized by self-imposed starvation, and has been linked to hyperactivity, a hallmark of AN. However, it remains unknown how leptin receptor (LepR) and its JAK2-STAT3 downstream pathway in extrahypothalamic brain areas, such as the dorsal (dHip) and ventral (vHip) hippocampus, crucial for spatial memory and emotion regulation, may contribute to the maintenance of AN behaviors. Taking advantage of the activity-based anorexia (ABA) model (i.e., the combination of food restriction and physical activity), we observed reduced leptin plasma levels in adolescent female ABA rats at the acute phase of the disorder [post-natal day (PND) 42], while the levels increased over control levels following a 7-day recovery period (PND49). The analysis of the intracellular leptin pathway revealed that ABA rats showed an overall decrease of the LepR/JAK2/STAT3 signaling in dHip at both time points, while in vHip we observed a transition from hypo- (PND42) to hyperactivation (PND49) of the pathway. These changes might add knowledge on starvation-induced fluctuations in leptin levels and in hippocampal leptin signaling as initial drivers of the transition from adaptative mechanisms to starvation toward the maintenance of aberrant behaviors typical of AN patients, such as perpetuating restraint over eating.

RESUMO

Cancer-related anorexia-cachexia (CRAC) comprises one of the most common syndromes of advanced cancer patients. The prevalence of CRAC increases from 50% to 80% before death. CRAC is associated not only with impaired quality of life in patients and family members but also with shorter survival. The management of CRAC is a great challenge in clinical practice. There are no definite practice guidelines yet for the prevention and treatment of CRAC. A multimodal strategy is the most effective way to treat anorexia-cachexia. Numerous medications have been suggested and used in clinical trials, while others are still being studied on experimental animals. These medications include branched-chain amino acids, eicosapentaenoic acid, thalidomide, cytokine inhibitors, steroids, antiserotoninergic medications, and appetite stimulants. The benefits of supportive care interventions and the advancement of exciting new pharmacological medicines for anorexia-cachexia are becoming more widely recognized. Health care professionals need to be aware of the psychosocial and biological effects of anorexia-cachexia, even though knowledge of the underlying molecular causes of the disorder has advanced significantly.

RESUMO

OBJECTIVE: Cancer-related anorexia-cachexia comprises one of the most common syndromes of advanced cancer patients. The management of cancer-related anorexia-cachexia is a great challenge in clinical practice. There are no definite practice guidelines yet for the prevention and treatment of cancer-related anorexia-cachexia. This study is considered to find out whether there is any role of mirtazapine in the improvement of anorexia in cancer patients. METHODS: A total of 80 cancer-anorexia patients were enrolled. Patients in the trial arm received the standard chemotherapy medication plus one tablet of mirtazapine 15 mg daily at night orally for 8 weeks starting from the day of an initial assessment. The control arm received the standard chemotherapy medication plus one tablet of megestrol acetate 160 mg daily orally for 8 weeks starting from the day of an initial assessment. Each patient was assessed by validated versions of Functional Assessment of Anorexia/Cachexia Therapy Anorexia/Cachexia Sub Scale v 4 questionnaires. RESULTS: After 4 and 8 weeks each patient was evaluated again using the Functional Assessment of Anorexia/Cachexia Therapy Anorexia/Cachexia Sub Scale tool. The quality of life of each patient was assessed by European Organization for Research and Treatment QLQ-C30 v 3.0. After 4 to 8 weeks of treatment, the Functional Assessment of Anorexia/Cachexia Therapy Anorexia/Cachexia Sub Scale score in cancer anorexia patients in the mirtazapine improved anorexia significantly. However, the improvement after 4 to 8 weeks was not statistically significant when it was compared with the megestrol acetate (P > 0.05). CONCLUSIONS: Therefore, the findings of this study reveal that mirtazapine might be a potential alternative to megestrol acetate, as it has shown potential efficacy as like as megestrol acetate.

RESUMO

Cancer cachexia (CC) syndrome, a feature of cancer-associated muscle wasting, is particularly pronounced in older patients, and is characterised by decreased energy intake and upregulated skeletal muscle catabolic pathways. To address CC, appetite stimulants, anabolic drugs, cytokine mediators, essential amino acid supplementation, nutritional counselling, cognitive behavioural therapy, and enteral nutrition have been utilised. However, pharmacological treatments that have also shown promising results, such as megestrol acetate, anamorelin, thalidomide, and delta-9-tetrahydrocannabinol, have been associated with gastrointestinal and cardiovascular complications. Emerging evidence on the efficacy of probiotics in modulating gut microbiota also presents a promising adjunct to traditional therapies, potentially enhancing nutritional absorption and systemic inflammation control. Additionally, low-dose olanzapine has demonstrated improved appetite and weight management in older patients undergoing chemotherapy, offering a potential refinement to current therapeutic approaches. This review aims to elucidate the molecular mechanisms underpinning CC, with a particular focus on the role of anorexia in exacerbating muscle wasting, and to propose pharmacological and non-pharmacological strategies to mitigate this syndrome, particularly emphasising the needs of an older demographic. Future research targeting CC should focus on refining appetite-stimulating drugs with fewer side-effects, specifically catering to the needs of older patients, and investigating nutritional factors that can either enhance appetite or minimise suppression of appetite in individuals with CC, especially within this vulnerable group.

RESUMO

Importance: Currently there is no standard therapy to improve cancer-related anorexia, hampering survival. Mirtazapine has been suggested as a feasible option in this context. Objectives: To assess the effect of mirtazapine on appetite and energy consumption in patients with advanced non-small cell lung cancer (NSCLC). Design, Setting, and Participants: This randomized, double-blind, placebo-controlled clinical trial including adults was performed in a tertiary cancer care center from August 2018 to May 2022 with a follow-up of 8 weeks. Overall, 134 patients were screened; 114 were assessed for eligibility and 28 were excluded. Interventions: Patients were randomized in a 1:1 ratio to receive mirtazapine, 15 mg, or placebo for 2 weeks followed by a dose escalation to 30 mg until week 8 or placebo. Both groups received nutritional assessment and dietary advice. Main outcomes and measures: Appetite was assessed by the Anorexia Cachexia Scale and energy intake. Dietary parameters were evaluated at baseline, 4 weeks, and 8 weeks, with a 24-hour dietary recall, and energy quantification based on the Mexican system of nutritional equivalents. Results: A total of 86 patients met the inclusion criteria and were randomized to the placebo (n = 43) or the mirtazapine group (n = 43). The mean (SD) age was 63.5 (11.2) years, 41 were women (57.7%) and had adenocarcinoma, Eastern Cooperative Oncology Group performance status scale score of 1, stage IV NSCLC, and were receiving first-line treatment. Baseline characteristics were similar between groups. There was no difference in appetite scores in patients who received mirtazapine or placebo after 4 and 8 weeks. After 4 weeks, mirtazapine significantly increased energy intake (379.3 kcal; 95% CI, 1382.6-576.1; P < .001) including proteins (22.5 g; 95% CI, 11.5-33.4; P = .001), carbohydrates (43.4 g; 95% CI, 13.1-73.8; P = .006), and fats (13.2 g; 95% CI, 6.0-20.4; P = .006). Fats intake was significantly higher in patients in the mirtazapine group (14.5 g vs 0.7 g; P = .02) after 8 weeks. The mirtazapine group significantly decreased the proportion of patients with sarcopenia (82.8% vs 57.1%, P = .03) at 8 weeks. Patients on mirtazapine tolerated the treatment well, but reported a higher perception of nightmares at 2 weeks based on a 10 cm VAS score (0 [25th-75th percentile, 0-1] vs 0 [25th-75th percentile, 0-0] in the control group; P = .009) but this finding was nonsignificant after 4 and 8 weeks. Conclusion and Relevance: In this randomized clinical trial of patients with advanced NSCLC, there was no difference in appetite scores in all patients who received mirtazapine or placebo, but the mirtazapine group had a significant increase in energy intake through the 4- and 8-week follow-up, mainly in fat intake, which is a better and crucial source of energy. The addition of mirtazapine in the treatment of patients with advanced NSCLC and anorexia may help these patients achieve their energy requirements and improve health-related quality of life, specifically emotional and cognitive functioning.

RESUMO

Healthcare professionals are frequently asked about the benefits of cannabis for appetite or anorexia-cachexia syndrome. In popular culture, cannabis has a reputation of causing an increased hunger, slang termed "the munchies," so many patients consume this with the hope that it may improve the loss of appetite associated with serious illness such as cancer. There have only been a few randomized, controlled trials studying the controversial question as to if cannabis improves appetite. These studies are small and show no statistically significant benefit for appetite and one small study showed improvement of taste for foods. Due to regulation barriers, the studies have use synthetic products, not the products that represent what is more commonly used in the population, often whole flower smoked, vaporized or oral products. Despite the popularity of cannabis in culture, often touted as a panacea for all maladies, the evidence and education for several adverse effects and potential drug interactions have has yet to catch up with the cultural craze. International cannabis experts in the United States and Australia do not routinely certify patients for medical cannabis off trial for anorexia-cachexia, but one expert in Canada would consider use in selected cancer patients.

RESUMO

The lack of specific treatments for anorexia nervosa (AN) is partly driven by an inadequate understanding of the neurobiological drivers of the condition. The activity-based anorexia (ABA) model recapitulates key characteristics of AN in rats and mice, and can be used to understand factors that predispose, maintain, and rescue anorectic behaviour. With the rapidly evolving suite of technologies to manipulate and record neural activity during the development of ABA, we are better placed than ever before to take advantage of this unique biobehavioural model in order to develop and refine novel treatments for AN. This will require a collective effort to bridge research disciplines in order to capitalise on knowledge gains from genetics, neurobiology, metabolism, and cognition.

RESUMO

OBJECTIVE: This study aimed to validate the assessment of anorexia in patients with acute stroke using the Simplified Nutritional Appetite Questionnaire. METHODS: This cross-sectional observational study assessed appetite using the Simplified Nutritional Appetite Questionnaire in patients with acute stroke at discharge from an acute care hospital. Additionally, the relationship between the Simplified Nutritional Appetite Questionnaire and Mini Nutritional Assessment, Mini Nutritional Assessment - Short Form scores, skeletal muscle mass, muscle strength, and activities of daily living measured using the Functional Independence Measures for the motor domain was investigated. A multiple regression analysis was conducted with the Functional Independence Measure for the motor domain as the dependent variable and the Simplified Nutritional Appetite Questionnaire and other confounding factors as explanatory variables to evaluate the association between the Simplified Nutritional Appetite Questionnaire and functional outcomes. RESULTS: Among the 234 patients with stroke analyzed in this study, the median Simplified Nutritional Appetite Questionnaire score was 15 (IQR = 13-16) points. The Simplified Nutritional Appetite Questionnaire score significantly correlated with weight change, Functional Independence Measure for the motor domain, nutritional assessment index, and energy and protein intake. However, no significant differences in body mass index, muscle mass, or muscle strength were observed. In the multiple regression analysis adjusted for confounders, the Simplified Nutritional Appetite Questionnaire score (ß = 0.106; P = 0.007) was independently associated with the Functional Independence Measure for the motor domain (adjusted R2 = 0.662). CONCLUSIONS: This study's results found a significant correlation between Simplified Nutritional Appetite Questionnaire scores and nutritional status as well as an independent association with functional outcomes in patients with stroke. These findings suggest that the Simplified Nutritional Appetite Questionnaire can be a valuable tool for evaluating anorexia in this patient population.

RESUMO

Alterations in the central nervous system in cancer patients are pivotal in determining appetite dysregulation and body weight loss (BWL). Autonomic nervous system activity was tested by measuring heart rate variability (HRV) in cancer patients presenting with anorexia. We considered inpatients with different types of cancer and investigated anorexia using their FAACT scores. HRV was evaluated by a three-channel Holter ECG. The domains of low frequencies (LF, sympathetic activity) and high frequencies (HF, parasympathetic activity) were calculated. Also, SDNN (autonomic activity) and RMSSD (parasympathetic activity) were assessed. We enrolled 56 patients with cancer and 23 controls. In cancer patients, RMSSD and SDNN were lower than in controls (p < 0.001 and p = 0.009). Sympathetic activity (LF nu) was lower in cancer patients than in controls (p = 0.023), including sympathovagal balance (LF/HF nu ratio) (p = 0.025). RMSSD was reduced in anorexic (p < 0.001) and non-anorexic (p = 0.003) cancer patients compared to controls. The SDNN was lower in anorexic cancer patients than in non-anorexic cancer patients (p = 0.025), and it was lower in anorexic cancer patients than in controls (p = 0.001). LF nu was lower in anorexic cancer patients than in controls (p = 0.015), as was LF/HF (p = 0.031). SDNN was negatively correlated with BWL in the cancer group (rho = -0.40; p = 0.007). Our data support the hypothesis that autonomic nervous system dysregulation exists in patients with cancer presenting with anorexia, with implications for its diagnosis and treatment.

RESUMO

BACKGROUND: Social isolation is a pervasive and debilitating condition that has adverse prognostic impacts. This condition often co-occurs with other geriatric syndromes, further exacerbating negative health outcomes. Given these considerations, the present study aims to elucidate the roles of social isolation in older adults with anorexia of aging and/or sarcopenia with respect to long-term mortality using a nationally representative cohort study. METHODS: Data were obtained from the Taiwan Longitudinal Study on Aging (TLSA), with a sample size of 3,762 study participants aged 50 years and older. Data from 1999 (wave 4) to 2015 (wave 9) were analyzed. The TLSA questionnaire was used to define social isolation, anorexia, and sarcopenia. Logistic regressions were employed to explore the associations between social isolation, anorexia, and sarcopenia. The Cox proportional hazard model was utilized to examine the synergistic effects of social isolation and anorexia or sarcopenia on 16-year all-cause mortality. RESULTS: After controlling for demographic information and comorbidities, older adults with social isolation were significantly associated with anorexia (adjusted odds ratio [aOR] 1.46 [95% confidence interval: 1.00-2.12, p=0.0475]) and sarcopenia (aOR 1.35 [95% CI: 1.12-1.64, p=0.0021]). Furthermore, the synergistic effects of social isolation with anorexia (aOR 1.65 [95% CI: 1.25-2.18, p=0.0004]) or sarcopenia (aOR 1.65 [95% CI: 1.42-1.92, p<0.0001]) were both significantly associated with higher risks of all-cause mortality, while social isolation alone revealed borderline statistical significance. CONCLUSIONS: Our findings indicate that social isolation is closely linked to anorexia and sarcopenia among middle-aged and older adults. Additionally, social isolation significantly exacerbates the long-term mortality risk associated with anorexia of aging and sarcopenia. However, social isolation alone appears to have borderline long-term mortality risk in this cohort. These findings underscore the importance of addressing social isolation in older adults with anorexia and/or sarcopenia to optimize their health outcomes and mitigate long-term mortality risk.

RESUMO

Cancer-related anorexia/cachexia syndrome (CACS) is characterized by anorexia and loss of body weight. Evidence is insufficient to strongly endorse any pharmacologic agent for the treatment of CACS. In this systematic review, we assessed the efficacy of oral anamorelin treatment for patients with CACS. On July 6, 2022, we systematically searched the following databases for randomized controlled trials (RCTs) of adults with CACS comparing oral anamorelin versus placebo: CENTRAL, PubMed, EMBASE, and ICHUSHI. The primary outcomes were total body weight (TBW), patient-reported quality of life (QOL), and adverse events (AEs). Secondary outcomes included lean body mass (LBM), overall survival (OS), non-dominant hand grip strength (HGS), and appetite. We included seven RCTs with a total of 1944 CACS patients. Anamorelin significantly increased TBW (mean difference (MD) 1.73, 95% confidence interval (CI) 1.34-2.13, p < 0.00001), LBM (MD 1.06, 95% CI 0.30-1.81, p = 0.006), and QOL (standardized mean difference (SMD) 0.16, 95% CI 0.04-0.27, p = 0.006) compared with placebo without a significant difference in all AEs, severe AEs, OS, HGS or appetite. Anamorelin may be an effective treatment for CACS patients; however, further studies are needed to confirm the efficacy and safety of this drug.

RESUMO

High rates of obesity, unhealthy eating behaviors, and eating disorders among children and adolescents have a very negative impact on their physical and mental health. The role of pediatricians and general practitioners is central in terms of prevention and screening. When a referral to a specialist is necessary, it is important to consider the bidirectional relationship between eating disorders and mental health problems. A history of obesity in a patient with mental anorexia leads to the need for specific management, particularly in relation to the concept of Weight Suppression (WS).


Les taux élevés d'obésité, d'habitudes alimentaires inadaptées et de troubles du comportement alimentaire chez les enfants et les adolescents ont un impact très négatif sur leur santé physique et mentale. Le rôle du pédiatre et du médecin généraliste est central en termes de prévention et de screening. Lorsqu'un relais vers le spécialiste est nécessaire, il est important de considérer la relation bidirectionnelle entre les troubles alimentaires et les problèmes de santé mentale. Des antécédents d'obésité chez un patient souffrant d'anorexie mentale conduisent à la nécessité d'adapter spécifiquement la prise en charge, notamment en lien avec le concept de Weight Suppression (WS).

RESUMO

BACKGROUND/AIM: Several reports have evaluated the efficacy and safety of concurrent radiotherapy with cetuximab (BRT) in patients with nasopharyngeal carcinoma (NPC). Combination therapy with cetuximab can be a treatment option for NPC. Although clinical data regarding the efficacy and safety of BRT without induction chemotherapy (ICT) or adjuvant chemotherapy is essential for the development of new therapeutic strategies, such data are rarely reported. PATIENTS AND METHODS: We retrospectively investigated a series of patients with NPC treated in our institution to evaluate the efficacy and safety of BRT. Eleven patients with newly diagnosed NPC were identified from an inpatient database from July 2015 to April 2018. Seven patients who received BRT were reviewed. RESULTS: All patients completed BRT without cessation of treatment. Six (85.7%) patients achieved a complete response and one (14.3%) achieved stable disease. The response rate was 85.7%. All patients with ≤T3 disease achieved a complete response. Both patients with T3 disease developed local recurrence, and one of the four patients with T1-2 disease developed distant metastases. The 1- and 3-year overall survival rates were 85.7% and 47.6%, respectively. The most common adverse events (AEs) were pharyngeal mucositis (100%), radiation dermatitis (100%), anorexia (28.6%), weight loss (28.6%), acneiform rash (28.6%), and dry mouth (28.6%). Grade 3 AEs were pharyngeal mucositis (42.9%), radiation dermatitis (28.6%), and anorexia (14.3%). No grade 4/5 AEs were observed. CONCLUSION: BRT for NPC was tolerable, but our findings suggest that BRT without induction chemotherapy or adjuvant chemotherapy is insufficient at least for ≥T3 disease.

RESUMO

BACKGROUND Alcohol abuse inhibits the ability of the liver to release glucose into the bloodstream, primarily by inhibiting gluconeogenesis, so chronic alcohol abusers exhibit hypoglycemia after drinking alcohol without eating; this is called alcohol-induced hypoglycemia. Central adrenal insufficiency (AI) is characterized by cortisol deficiency due to a lack of adrenocorticotropic hormone. It is challenging to diagnose central AI, as it usually presents with nonspecific symptoms, such as asthenia, anorexia, and a tendency toward hypoglycemia. Here, we report a rare case of central AI that presented with AI symptoms shortly after an alcohol-induced hypoglycemic coma. CASE REPORT An 81-year-old Japanese man who had been a moderate drinker for >40 years developed a hypoglycemic coma after consuming a large amount of sake (alcohol, 80 g) without eating. After the hypoglycemia was treated with a glucose infusion, he rapidly recovered consciousness. After stopping alcohol consumption and following a balanced diet, he had normal plasma glucose levels. However, 1 week later, he developed asthenia and anorexia. The endocrinological investigation results indicated central AI. He was started on oral hydrocortisone (15 mg/day), which relieved his AI symptoms. CONCLUSIONS Cases of central AI associated with alcohol-induced hypoglycemic attacks have been reported. Our patient developed AI symptoms following an alcohol-induced hypoglycemic attack. His alcohol-induced hypoglycemic attack likely occurred in combination with a developing cortisol deficiency. This case highlights the importance of considering central AI in chronic alcohol abusers presenting with nonspecific symptoms, including asthenia and anorexia, especially when patients have previously experienced alcohol-induced hypoglycemic attacks.

RESUMO

Anorexia nervosa (AN) is a chronic, life-threatening disease with mental and physical components that include excessive weight loss, persistent food restriction, and altered body image. It is sometimes accompanied by hyperactivity, day-night reversal, and amenorrhea. No medications have been approved specific to the treatment of AN, partially due to its unclear etiopathogenesis. Because adiponectin is an appetite-regulating cytokine released by adipose tissue, we hypothesized that it could be useful as a specific biomarker that reflects the disease state of AN, so we developed a modified AN mouse model to test this hypothesis. Twenty-eight 3-week-old female C57BL/6J mice were randomly assigned to the following groups: 1) no intervention; 2) running wheel access; 3) food restriction (FR); and 4) activity-based anorexia (ABA) that included running wheel access plus FR. After a 10-day cage adaptation period, the mice of the FR and ABA groups were given 40% of their baseline food intake until 30% weight reduction (acute FR), then the body weight was maintained for 2.5 weeks (chronic FR). Running wheel activity and the incidence of the estrous cycle were assessed. Spontaneous food restriction and the plasma adiponectin level were evaluated at the end of the acute and chronic FR phases. An increase in running wheel activity was found in the light phase, and amenorrhea was found solely in the ABA group, which indicates that this is a good model of AN. This group showed a slight decrease in spontaneous food intake accompanied with an attenuated level of normally induced plasma adiponectin at the end of the chronic FR phase. These results indicate that the plasma adiponectin level may be a useful candidate biomarker for the status or stage of AN.

Adult hemophagocytic lymphohistiocytosis is a lifethreatenning disease which has hepatic manifestations mimicking acute hepatitis or can present with fulminant hepatic failure. The undelying pathophysiology is immune dysregulation causing a hyperinflammatory state. Clues to diagnosis include extremely high ferritin levels, whereas definitive diagnosis is usually made by bone marrow, as opposed to liver biopsy. Even with early and appropriate treatment with weekly dexamethasone and etoposide, mortality remains high.

RESUMO

INTRODUCTION: Cancer patients often suffer from malnutrition and early detection and raising awareness of nutritional issues is crucial in this population. METHODS: The Spanish Oncology Society (SEOM) conducted the Quasar_SEOM study to investigate the current impact of the Anorexia-Cachexia Syndrome (ACS). The study employed questionnaires and the Delphi method to gather input from both cancer patients and oncologists on key issues related to early detection and treatment of ACS. A total of 134 patients and 34 medical oncologists were surveyed about their experiences with ACS. The Delphi methodology was used to evaluate oncologists' perspectives of ACS management, ultimately leading to a consensus on the most critical issues. RESULTS: Despite widespread acknowledgement of malnutrition in cancer as a significant issue by 94% of oncologists, the study revealed deficiencies in knowledge and protocol implementation. A mere 65% of physicians reported being trained to identify and treat these patients, with 53% failing to address ACS in a timely manner, 30% not monitoring weight, and 59% not adhering to any clinical guidelines. The lack of experience was identified as the primary hindrance to the use of orexigens in 18% of cases. Furthermore, patients reported concerns and a perception of inadequate attention to malnutrition-related issues from their physicians. CONCLUSION: The results of this study point to a gap in the care of this syndrome and a need to improve education and follow-up of cancer patients with anorexia-cachexia.

RESUMO

Cancer cachexia is a complex multifaceted syndrome involving functional impairment and changes in body composition that cannot be reversed by nutritional support. Cancer cachexia is characterized by decreased skeletal muscle mass, increased lipolysis, and decreased food intake. Cancer cachexia decreases chemotherapy tolerance as well as quality of life. However, because no fully effective interventions are available, cancer cachexia remains an unmet need in cancer treatment. In recent years, several discoveries and treatments for cancer cachexia have been studied, and guidelines have been published. We believe that the development of effective strategies for the diagnosis and treatment of cancer cachexia will lead to breakthroughs in cancer treatment.
