AIDS wasting syndrome is a condition characterised by weight loss, particularly in muscles. Muscle weakness and wasting in people with HIV/AIDS can be caused by a variety of factors, including malnutrition, amino acid deficiencies, glutamine deficiency, and HIV-associated neuromuscular weakness syndrome (HANWS). HANWS is characterised by rapidly progressive weakness, nausea, vomiting, weight loss, abdominal distension, hepatomegaly, and lipoatrophy. Additionally, certain HIV medications can cause muscle weakness as a side effect. Treatments for muscle wasting in people with HIV/AIDS include nutritional supplementation, cytokine reduction, hormone therapy, and resistance exercise training.

What You'll Learn
Amino acid deficiencies
AIDS wasting syndrome is characterised by weight loss, muscle and fat depletion, and extreme weakness. Amino acid deficiencies can sometimes be the underlying cause of muscle weakness. Muscle is mostly made up of protein, which is itself made up of amino acids. Therefore, essential amino acid deficiencies can cause muscle weakness.
Deficiencies can result from poor protein digestion. Gas or bloating after meals can be a sign of poor protein digestion. If this is an ongoing problem, and you are experiencing muscle weakness, it is recommended that you consult a healthcare professional about the possibility of an amino acid deficiency.
Glutamine is an amino acid often deficient in people living with HIV. It is involved in many aspects of healthy body function, including maintaining antioxidant levels, building and maintaining muscle tissue, strengthening immune function, and repairing and maintaining intestinal tissue. L-glutamine is an essential amino acid required for protein synthesis. During stress and inflammation, the need for L-glutamine exceeds the rate of production, and skeletal muscle is catabolised to provide this amino acid to other parts of the body. L-glutamine is also necessary for many metabolic processes, including tissue repair.
To increase lean tissue mass and improve muscular strength in HIV-infected persons, nutritional interventions can be used to supplement for specific amino acid deficiencies. Resistance exercise training has also been found to increase lean tissue mass in HIV-infected populations.

HIV-associated neuromuscular weakness syndrome
AIDS can cause muscle weakness, and HIV-associated neuromuscular weakness syndrome (HANWS) is a recognised condition. Neuromuscular disorders are common in HIV, occurring at all stages of the disease and affecting all parts of the peripheral nervous system.
The causes of HIV-associated neuromuscular weakness syndrome are diverse, and can include HIV itself, immune suppression and dysregulation, co-morbid illnesses and infections, and side effects of medications. Certain antiretroviral drugs may lead to toxic myopathy, presumably through impairment of mitochondrial function. Zidovudine (AZT) myopathy, for example, can manifest as fixed weakness or exercise intolerance which resolves within months of withdrawing the drug. Stavudine (d4T), which is now rarely used in wealthy countries, can cause HIV-associated neuromuscular weakness syndrome.
HANWS is characterised by rapidly progressive weakness, resembling Guillain-Barre syndrome, associated with lactic acidosis, nausea, vomiting, weight loss, abdominal distension, hepatomegaly and lipoatrophy. In a study of 69 patients, severe axonal polyneuropathy was the most common diagnosis, however, demyelinating and mixed neuropathies, as well as myopathy, also occurred. Muscle biopsies revealed evidence of mitochondrial dysfunction, including ragged red fibres and depletion of mitochondrial DNA.
Other neuromuscular complications of HIV include distal symmetric polyneuropathy, inflammatory demyelinating polyneuropathy, mononeuropathy, mononeuropathy multiplex, autonomic neuropathy, progressive polyradiculopathy due to cytomegalovirus, herpes zoster, myopathy and other rarer disorders.

Cytomegalovirus co-infection
AIDS, or acquired immunodeficiency syndrome, is a condition caused by the human immunodeficiency virus (HIV) that damages the immune system over time, making it harder for the body to fight off infections and diseases. One of the many complications of AIDS is muscle weakness, which can be caused by a variety of factors, including co-infections.
Cytomegalovirus (CMV) co-infection is one of the possible causes of muscle weakness in AIDS patients. CMV is a common virus that belongs to the herpes family and can cause serious health problems in people with weakened immune systems, such as those with AIDS. CMV can infect the cauda equina, leading to inflammation and necrosis of the lumbosacral nerve roots and a progressive polyradiculopathy. This condition is known as CMV-related mononeuropathy multiplex and presents with weakness and numbness in the lower extremities, sphincter dysfunction, and flaccid paraparesis. In advanced cases, the upper extremities and cranial nerves may also be involved.
CMV co-infection can also cause severe neuropathy in AIDS patients, resulting in progressive neuromuscular disorders with sensory components, severe weakness, muscle wasting, and fasciculations. Atrophy of the spinal cord and evidence of HIV-like immunoreactivity in rare anterior horn cells have also been observed in some cases. Additionally, CMV infection has been associated with painful peripheral neuropathy in AIDS patients, further contributing to muscle weakness and discomfort.
The treatment for CMV co-infection in AIDS patients involves managing both the AIDS and the CMV infection. Highly active anti-retroviral therapy (HAART) has been shown to improve longevity in patients living with HIV. Specific treatments for CMV-related mononeuropathy multiplex include plasmapheresis, high-dose corticosteroids, intravenous immune globulin, and ganciclovir. However, despite treatment, CMV co-infection can lead to severe complications and even death in AIDS patients, making early diagnosis and intervention crucial.

Nutritional supplementation
HIV attacks the body's immune system, destroying white blood cells needed to fight off infections. People living with HIV have higher energy needs and are at a higher risk of developing nutrient deficiencies. Nutritional supplementation, cytokine reduction, hormone therapy, and resistance exercise training are all potential treatments for muscle weakness in HIV-infected individuals.
Protein helps build muscles, organs, and a strong immune system. HIV-positive people should aim to consume 100-150 grams of protein per day (men) and 80-100 grams per day (women). Good sources of protein include chicken, fish, eggs, beans, and protein powder. Nutritional supplements containing high amounts of protein can help people with HIV gain muscle mass and body weight.
In addition to protein, people with HIV should focus on including a variety of carbohydrates and fats in their diet. Carbohydrates provide energy, and a mix of fruits and vegetables ensures a wide range of nutrients. Examples of healthy fats include nut butter, Greek yogurt, and olive oil.
Vitamin and mineral supplements can also be beneficial for people with HIV. Vitamin D, for example, can help reduce ART-related complications like decreased bone mineral density. Calcium supplements are also recommended for those who do not consume enough calcium through their diet.
It is important to note that individual nutrient needs vary among people with HIV, so personalized advice from a medical professional is essential.

Resistance exercise training
HIV-infected patients often experience disability, muscle wasting, weakness, and lower aerobic capacity. Resistance exercise training has been found to be an effective strategy to improve muscle weakness and aerobic capacity in HIV-infected patients.
Resistance training, when combined with aerobic exercise, is known as combined aerobic and resistance exercise (CARE). CARE has been shown to improve muscle strength, health status, energy, and physical function in HIV-infected individuals. It also resulted in a significant improvement in the handgrip, lower-limb strength, agility, gait speed, postural stability, functional performance, fat mass, and muscle mass.
A progressive resistance training program for elderly HIV-positive patients included three sets of 8-12 repetitions of leg press, seated row, lumbar extension, and chest press, performed with free weight machines twice a week for a year. The strengths of major muscle groups increased by 74%-122%, with a corresponding improvement in sit-standing and walking times.
Resistance training is more accessible to HIV-infected individuals than other treatments for muscle wasting and has been successfully used to increase lean tissue mass. It is a highly effective preventive strategy to delay and attenuate the negative effects of sarcopenia and frailty in both the early and late stages of HIV.
