Human immunodeficiency virus (HIV) is a condition that weakens the immune system by attacking the white blood cells responsible for fighting infection, thus increasing the risk of various cancers and opportunistic infections. The most severe stage of HIV is known as acquired immunodeficiency syndrome (AIDS), which occurs during stage 3 of the disease. In the absence of treatment, the average survival time for HIV is approximately eight to 10 years, with a staggering mortality rate of 90%. Initially, individuals may experience a prolonged period without any symptoms or only mild flu-like symptoms. While a cure for HIV has not yet been discovered, there are numerous antiretroviral treatments available within the HIV drug class that effectively slow down the progression of the disease, reduce transmission rates, and significantly extend the lifespan of individuals infected with the virus, according to the Centers for Disease Control and Prevention (CDC).
What is Post-Exposure Prophylaxis (PEP)?
Post-Exposure Prophylaxis (PEP) is a preventive treatment that can be administered within 72 hours after potential exposure to HIV in order to prevent infection. This treatment is commonly used in emergency situations, such as accidental needle sticks among medical professionals, instances of sexual assault, and the sharing of needles.
PEP treatment has proven to be effective in most exposure situations. The key to its effectiveness lies in the prompt administration of the treatment following exposure. The sooner the treatment is given, the more likely it is to prevent HIV infection from occurring.
Protease Inhibitors for HIV Treatment
Protease enzymes are crucial for various functions in the human body, including immune support, blood clotting, cell division, and protein recycling. In the context of HIV treatment, medications known as protease inhibitors (PIs) are used to block viral proteases. These proteases are essential for the replication of the HIV virus. By binding to these proteases, PIs effectively reduce the viral load and slow down the progression of HIV. However, it is important to note that protease inhibitors can have certain side effects. These may include insulin resistance, liver problems, and a noticeable alteration in the sense of taste when consuming food.
