Targeted Approach

Cancer cachexia has two main components: anorexia and metabolic alterations. The main changes associated with the development of this multi-organic syndrome are glucose intolerance, fat depletion and muscle protein hypercatabolism. The aim of this paper is to review the more recent therapeutic approaches designed to counteract the wasting suffered by the cancer patient with cachexia. Among the most promising approaches we can include the use of ghrelin agonists, beta-blockers, beta-adrenergic agonists, androgen receptor agonists and anti-myostatin peptides. The multi-targeted approach seems essential in these treatments, which should include the combination of both nutritional support, drugs and a suitable program of physical exercise, in order to ameliorate both anorexia and the metabolic changes associated with cachexia. In addition, another very important and crucial aspect to be taken into consideration in the design of clinical trials for the treatment of cancer cachexia is to staging cancer patients in relation with the degree of cachexia, in order to start as early as possible this triple approach in the course of the disease, even before the weight loss can be detected.

Anorexia and metabolic alterations are the main components of the cachectic syndrome. Glucose intolerance, fat depletion, muscle protein catabolism and other alterations are involved in the development of cancer cachexia, a multi-organ syndrome. Nutritional approach strategies are not satisfactory in reversing the cachectic syndrome. The aim of the present review is to deal with the recent therapeutic targeted approaches that have been designed to fight and counteract wasting in cancer patients. Indeed, some promising targeted therapeutic approaches include ghrelin agonists, selective androgen receptor agonists, β-blockers and antimyostatin peptides. However, a multi-targeted approach seems absolutely essential to treat patients affected by cancer cachexia. This approach should not only involve combinations of drugs but also nutrition and an adequate program of physical exercise, factors that may lead to a synergy, essential to overcome the syndrome. This may efficiently reverse the metabolic changes described above and, at the same time, ameliorate the anorexia. Defining this therapeutic combination of drugs/nutrients/exercise is an exciting project that will stimulate many scientific efforts. Other aspects that will, no doubt, be very important for successful treatment of cancer wasting will be an optimized design of future clinical trials, together with a protocol for staging cancer patients in relation to their degree of cachexia. This will permit that nutritional/metabolic/pharmacological support can be started early in the course of the disease, before severe weight loss occurs. Indeed, timing is crucial and has to be taken very seriously when applying the therapeutic approach.

Skeletal Muscle Loss

With the growing number of dialysis patients with frailty, the concept of renal rehabilitation, including exercise intervention and nutrition programs for patients with chronic kidney disease (CKD), has become popular recently. Renal rehabilitation is a comprehensive multidisciplinary program for CKD patients that is led by doctors, rehabilitation therapists, diet nutritionists, nursing specialists, social workers, pharmacists, and therapists. Many observational studies have observed better outcomes in CKD patients with more physical activity. Furthermore, recent systematic reviews have shown the beneficial effects of exercise intervention on exercise tolerance, physical ability, and quality of life in dialysis patients, though the beneficial effect on overall mortality remains unclear. Nutritional support is also fundamental to renal rehabilitation. There are various causes of skeletal muscle loss in CKD patients. To prevent muscle protein catabolism, in addition to exercise, a sufficient supply of energy, including carbohydrates, protein, iron, and vitamins, is needed. Because of decreased digestive function and energy loss due to dialysis treatment, dialysis patients are recommended to ingest 1.2-fold more protein than the regular population. Motivating patients to join in activities is also an important part of renal rehabilitation. It is essential for us to recognize the importance of renal rehabilitation to maximize patient satisfaction.

The influence of cancer cachexia and chemotherapy and subsequent recovery of skeletal muscle protein mass and turnover was investigated in mice. Cancer cachexia was induced using colon 26 adenocarcinoma, which is characteristic of the human condition, and can be cured with 100% efficacy using an experimental nitrosourea, cystemustine (C6H12CIN3O4S). Reduced food intake was not a factor in these studies. Three days after cachexia began, healthy and tumor-bearing mice were given a single intraperitoneal injection of cystemustine (20 mg/kg). Skeletal muscle mass in tumor-bearing mice was 41% lower ( P < 0.05) than in healthy mice 2 wk after cachexia began. Skeletal muscle wasting was mediated initially by decreased protein synthesis (−38%; P < 0.05) and increased degradation (+131%; P < 0.05); later wasting resulted solely from decreased synthesis (∼−54 to −69%; P < 0.05). Acute cytotoxicity of chemotherapy did not appear to have an important effect on skeletal muscle protein metabolism in either healthy or tumor-bearing mice. Recovery began 2 days after treatment; skeletal muscle mass was only 11% lower than in healthy mice 11 days after chemotherapy. Recovery of skeletal muscle mass was affected initially by decreased protein degradation (−80%; P < 0.05) and later by increased protein synthesis (+46 to +73%; P < 0.05) in cured compared with healthy mice. This study showed that skeletal muscle wasted from cancer cachexia and after chemotherapeutic treatment is able to generate a strong anabolic response by making powerful changes to protein synthesis and degradation.

Abstract COVID-19, the global threat to humanity, shares etiological cofactors with multiple diseases including Alzheimer’s disease (AD). Understanding the common links between COVID-19 and AD would harness strategizing therapeutic approaches against both. Considering the urgency of formulating COVID-19 medication, its AD association and manifestations have been reviewed here, putting emphasis on memory and learning disruption. COVID-19 and AD share common links with respect to angiotensin-converting enzyme 2 (ACE2) receptors and pro-inflammatory markers such as interleukin-1 (IL-1), IL-6, cytoskeleton-associated protein 4 (CKAP4), galectin-9 (GAL-9 or Gal-9), and APOE4 allele. Common etiological factors and common manifestations described in this review would aid in developing therapeutic strategies for both COVID-19 and AD and thus impact on eradicating the ongoing global threat. Thus, people suffering from COVID-19 or who have come round of it as well as people at risk of developing AD or already suffering from AD, would be benefitted.

Uveal melanoma (UM), which is the most common cancer of the eye, was investigated in recent years by many teams in the field of biomedical sciences and eye clinicians. New knowledge was acquired on molecular pathways found to be dysregulated during the multistep process of oncogenesis, whereas novel therapeutic approaches gave significant results in the clinical applications. Uveal melanoma-affected patients greatly benefited from recent advances of the research in this eye cancer. Tumour biology, genetics, epigenetics and immunology contributed significantly in elucidating the role of different genes and related pathways during uveal melanoma onset/progression and UM treatments. Indeed, these investigations allowed identification of new target genes and to develop new therapeutic strategies/compounds to cure this aggressive melanoma of the eye. Unfortunately, the advances reported in the treatment of cutaneous melanoma have not produced analogous benefits in metastatic uveal melanoma. Nowadays, no systemic adjuvant therapy has been shown to improve overall survival or reduce the risk of metastasis. However, the increasing knowledge of this disease, and the encouraging results seen in clinical trials, offer promise for future effective therapies. Herein, different pathways/genes involved in uveal melanoma onset/progression were taken into consideration, together with novel therapeutic approaches.

Circulating Levels

Cachexia is a devastating pathology induced by several kinds of diseases, including cancer. The hallmark of cancer cachexia is an extended weight loss mainly due to skeletal muscle wasting and fat storage depletion from adipose tissue. The latter exerts key functions for the health of the whole organism, also through the secretion of several adipokines. These hormones induce a plethora of effects in target tissues, ranging from metabolic to differentiating ones. Conversely, the decrease of the circulating level of several adipokines positively correlates with insulin resistance, metabolic syndrome, diabetes, and cardiovascular disease. A lot of findings suggest that cancer cachexia is associated with changed secretion of adipokines by adipose tissue. In agreement, cachectic patients show often altered circulating levels of adipokines. This review reported the findings of adipokines (leptin, adiponectin, resistin, apelin, and visfatin) in cancer cachexia, highlighting that to study in-depth the involvement of these hormones in this pathology could lead to the development of new therapeutic strategies.
