Biktarvy is a medication used to treat HIV-1 that combines three antiviral medicines: bictegravir, emtricitabine, and tenofovir. While Biktarvy is an effective treatment for HIV, it can cause a range of side effects, including muscle pain and weakness. The medication affects the immune system and can cause lactic acidosis, a buildup of lactic acid in the blood, resulting in muscle pain, cramps, and weakness. It is important for patients taking Biktarvy to be aware of these potential side effects and to consult their healthcare provider if they experience any unusual symptoms, as some side effects can be serious or life-threatening.

Lactic acidosis
Lactic acid, also known as lactate, is a natural byproduct of cellular metabolism. Our cells produce lactate when they need immediate energy that cannot be supplied by oxygen. This process is called anaerobic glycolysis, and it serves as an emergency backup to our usual aerobic metabolism, which relies on oxygen for energy production. While lactic acidosis can occur as a temporary side effect of overexercising, it can also be caused by certain diseases and medical conditions.
Diseases that can cause lactic acidosis include pulmonary and circulatory disorders that deprive the blood or tissues of oxygen. Additionally, underlying conditions such as liver or kidney disease, vitamin B1 deficiency, and mitochondrial diseases can inhibit the body's ability to metabolize lactate, leading to lactic acidosis. Certain medications, such as beta-adrenergic agonist inhalers, antiretroviral therapy, and antibiotics, have also been associated with lactic acidosis as a rare but serious side effect.
The symptoms of lactic acidosis can vary depending on its severity and underlying causes. Some common symptoms include muscle pain or weakness, numbness or cold feeling, trouble breathing, stomach pain, vomiting, irregular heart rate, dizziness, and a general feeling of weakness or tiredness. Lactic acidosis can be diagnosed through blood tests that measure lactate and electrolyte levels, as well as corrected anion gap calculations and arterial blood gas analyses. Management strategies for lactic acidosis include fluid resuscitation, vasopressor use, and renal replacement therapy.

Muscle wasting is a common feature of chronic liver disease, found in approximately 40% of patients with cirrhosis. It is considered one of the major complications of end-stage liver disease, and its incidence increases with disease progression. Muscle wasting is defined as the progressive and generalized loss of muscle mass. It is independently associated with mortality and is a significant predictor of survival rates in patients with cirrhosis.
The primary cause of muscle depletion is ageing, but the cause of sarcopenia, or muscle loss, is multifactorial. Sarcopenia is a major component of malnutrition and occurs in the majority of patients with liver disease. It is associated with increased mortality and the risk of developing other complications of cirrhosis. Unfortunately, there are no effective therapies to prevent or reverse sarcopenia in liver disease.
Several mechanisms contribute to muscle wasting in patients with liver cirrhosis. One important mechanism is reduced intestinal absorption due to maldigestion caused by pancreatic insufficiency, drug-related diarrhoea, or intestinal bacterial overgrowth. Additionally, disturbances in metabolic rates, such as increased energy expenditure, high protein catabolism, insulin resistance, and increased fat turnover, can result in a hypermetabolic state.
