Cushing's syndrome is an uncommon condition caused by prolonged exposure to high levels of glucocorticoids, resulting in a range of symptoms, including skin changes, metabolic issues, and muscle weakness. Proximal myopathy, characterised by difficulties in climbing stairs, walking, and standing, is a significant discriminatory sign of Cushing's syndrome. While there is no specific therapy available for the associated myopathy, the current treatment recommendations include adequate protein intake and moderate physical exercise. Surgical remission is considered the most crucial step for the recovery of muscle function, and further treatment options include medications, radiation, and chemotherapy.

What You'll Learn
Surgery
Cushing's syndrome is a rare condition that arises from prolonged exposure to high levels of glucocorticoids, resulting in a range of symptoms, including muscle wasting and weakness. While there is no specific therapy available for the treatment of muscle wasting in Cushing's syndrome, surgical intervention is often necessary to achieve remission and facilitate the recovery of muscle function.
In one case report, a 36-year-old man with Cushing's disease presented with proximal muscle weakness, making walking, climbing stairs, and standing difficult. Despite initial treatment with corticosteroids and immunosuppressants, his condition deteriorated, and he eventually became wheelchair-bound. Subsequent surgery, followed by a second procedure six months later, led to significant improvements in his muscle weakness. Within a year, he was able to walk unassisted and continued to recover with the aid of various medications and supplements.
The success of surgical remission in treating muscle wasting and restoring muscle function depends on several factors, including age, the presence of co-morbidities, and postoperative insulin-like growth factor concentrations. It is important to note that the treatments for Cushing's syndrome, including surgery, can be uncomfortable for the patient. However, they are often worth undergoing as they can lead to a cure for the syndrome and its associated symptoms.
While surgery can be an effective treatment for Cushing's syndrome and its related muscle wasting, it is not the only option. Other treatments, such as medications, radiation, and chemotherapy, may also be recommended by healthcare providers depending on the specific case and patient condition.

Medication
Cushing's syndrome is a rare condition that occurs due to prolonged exposure to high levels of glucocorticoid, a steroid hormone known as cortisol or the "stress hormone". The syndrome is characterised by various symptoms, including muscle weakness and muscle wasting, which predominantly affects the proximal part of the limbs. This muscle weakness is a crucial discriminatory sign of Cushing's syndrome.
In some cases, Cushing's syndrome may be induced by medications containing cortisol, which is prescribed for other conditions such as asthma and rheumatoid arthritis. Therefore, it is crucial to consult a healthcare provider to review any medications being taken and adjust them if necessary.
Additionally, glucocorticoid-induced muscle atrophy and myopathy have been extensively studied, and ultrasound-based detection methods have been proposed to identify muscle impairments early. This can help guide treatment decisions and potentially prevent or mitigate muscle wasting.
While there is no specific medication for muscle wasting in Cushing's syndrome, treating the underlying condition and managing symptoms are crucial. This may involve a multidisciplinary approach, including endocrinologists and other specialists, to ensure comprehensive care.

Radiation
Cushing's syndrome, or hypercortisolism, is a rare condition that occurs when the body has too much of the steroid hormone cortisol, also known as the "stress hormone". Proximal muscle wasting and weakness are typical side effects of Cushing's syndrome, which can be caused by the use of glucocorticoids to treat the disease.
The time to remission with radiation therapy is unpredictable, and medical therapy to lower cortisol production may be required in the interim. Radiation therapy does not result in immediate control of cortisol production, and it may take years for cortisol levels to return to normal. During this time, patients may need to take cortisol medications such as hydrocortisone tablets, which can be stopped after 6 to 18 months.
There are several complications associated with radiation therapy, including adverse effects on vision and normal brain tissue. Older methods of fractionated radiation delivery can also cause vasculopathy and increase the risk of cerebrovascular disease. However, more targeted methods of delivery are now being used, which may reduce these risks.
It is important to discuss all potential side effects with a healthcare provider before undergoing radiation therapy, as the treatment can be uncomfortable.

Chemotherapy
Cushing's syndrome is a rare condition characterised by prolonged exposure to high levels of cortisol, a steroid hormone commonly known as the "stress hormone". The most common cause of Cushing's syndrome is a tumour in the brain's pituitary gland, which produces high amounts of adrenocorticotropic hormone (ACTH). Proximal muscle weakness and muscle wasting are important discriminatory signs of Cushing's syndrome.
In some cases, Cushing's syndrome may be caused by an ACTH-producing tumour in a different part of the body, such as the nose. If the tumour is cancerous and has spread to other parts of the body, chemotherapy is necessary. Chemotherapy drugs work by killing cancer cells, which can help to shrink the tumour and reduce the overproduction of cortisol. This, in turn, may help to alleviate the symptoms of Cushing's syndrome, including muscle wasting.
It is important to note that chemotherapy can have significant side effects, and patients should discuss these with their healthcare providers before starting treatment. Additionally, other treatments for Cushing's syndrome, such as surgery, medication, and radiation therapy, may be considered as part of a comprehensive treatment plan.
While there is no specific therapy currently available for Cushing's syndrome-associated myopathy, maintaining adequate protein intake and engaging in moderate physical exercise may be recommended to help manage muscle weakness and wasting. In some cases, muscle weakness may dramatically improve or even resolve after successful treatment of Cushing's syndrome.

Adequate protein intake and moderate physical exercise
Cushing's syndrome is a group of symptoms caused by high levels of cortisol, a stress hormone, in the body. It can lead to muscle weakness and thinner arms and legs due to reduced muscle mass. This is known as Cushing's syndrome-associated myopathy, which affects the proximal part of the limbs, impairing stair climbing and straightening up.
Adequate Protein Intake
Eating enough protein can help keep muscles in good shape. It is important to make smart food choices to give your body the tools it needs to manage the effects of excess cortisol. A healthy diet combined with proper treatment can improve your quality of life.
Moderate Physical Exercise
Exercise is important for people living with Cushing's syndrome. It is recommended to exercise frequently and consistently. There are specific exercises designed to help with rehabilitation, symptom relief, and general health and wellness, developed in collaboration with physiotherapists. These exercises focus on strengthening the core and improving flexibility, such as the 4-point kneeling position, where you bring your leg outwards while squeezing your tummy and feeling your bottom muscles engage.
It is important to consult a doctor or physiotherapist for guidance on the appropriate level of exertion during exercise, especially if you have other conditions that may impact your ability to exercise.

Frequently asked questions
Cushing's disease is a rare condition that occurs when the body has excessive levels of cortisol, a hormone that is released during times of stress. This can be caused by a benign tumour in the pituitary gland, which secretes too much adrenocorticotropic hormone (ACTH), leading to increased cortisol secretion from the adrenal glands.
Symptoms of Cushing's disease include skin changes such as acne and skin infections, increased fat accumulation in the face, neck, trunk, and intra-abdominal areas, proximal muscle weakness and wasting, and various other musculoskeletal, cardiovascular, metabolic, and psychiatric issues.
Cushing's disease can be treated through surgery, medications, radiation, and chemotherapy. While these treatments may be uncomfortable, they are effective in curing the disease. It is important to consult a healthcare provider for guidance and support throughout the treatment process.
Muscle wasting in Cushing's disease can be treated by addressing the underlying condition. Surgical remission of Cushing's syndrome is crucial for the recovery of muscle function. Additionally, adequate protein intake and moderate physical exercise are recommended to support muscle health.
