Background
  • Wiskott-Aldrich syndrome (WAS) is an inherited, immunodeficiency disorder that occurs almost exclusively in males. The recessive genetic disorder is caused by a mutation in the WAS (Wiskott-Aldrich syndrome) gene, which is an X-linked trait. The gene mutation leads to abnormalities in B- and T-lymphocytes (white blood cells), as well as blood platelet cells. In a healthy individual, the T-cells provide protection against viral and fungal infection, the B cells produce antibodies, and platelets are responsible for blood clotting to prevent blood loss after a blood vessel injury.
  • Individuals diagnosed with WAS suffer from recurrent infections, eczema and thrombocytopenia (low levels of platelets).
  • Before 1935, patients only lived an average of eight months. Today, patients usually live an average of eight years, according to a recent case study. The cause of death is usually attributed to extensive blood loss. However, cancer (especially leukemia) is common and often fatal among WAS patients.
  • The only possible cure for WAS is a bone marrow transplant. However, if a patient's family member is not a possible match for a bone marrow donation, patients may have to wait years for a potential donor. Other aggressive treatments may also increase a patient's life expectancy. For instance, one study found that patients who underwent splenectomy (removal of the spleen) lived to be more than 25 years old. The spleen may harbor too many platelets, and cause a decrease in the number of platelets in circulation. Antibiotics, antivirals, antifungals, chemotherapeutic agents, immunoglobulins and corticosteroids have also been used to relieve symptoms and treat infections and cancer associated with WAS.
  • Researchers estimate that about four people per one million live male births develop the disease in the United States.
  • The syndrome is named after Dr. Robert Anderson Aldrich, an American pediatrician who described the disease in a family of Dutch-Americans in 1954, and Dr Alfred Wiskott, a German pediatrician who discovered the syndrome in 1937. Wiskott described three brothers with a similar disease, whose sisters were unaffected.

Function
  • Once HIV infects a human cell, the virus copies its own genetic makeup into the cell's DNA. This programs the human cell to produce new copies of HIV. The infected cell makes a long strand of genetic material that must be cut up and put back together in order to form new copies of HIV. The protease enzyme is responsible for "cutting up" these strands. Without the protease enzyme, the virus cannot replicate.
  • Protease inhibitors (PIs) prevent the protease enzyme from doing its job. Like a key fitting into a lock, PIs inhibit the activity of the protease enzyme. When protease is blocked, HIV makes copies of itself that are unable to infect new cells. Studies have shown that protease inhibitors can reduce the amount of virus in the blood and increase CD4 cell counts. These drugs have shown to effectively increase CD4 cell counts, even when counts are extremely low.

Uses
  • NSAIDs are primarily used to reduce inflammation, pain (mild to moderate), and low-grade fever. The anti-inflammatory effects may take anywhere from a few days to three weeks to initiate.
  • Specific uses include the treatment of headaches, arthritis (including osteoarthritis and rheumatoid arthritis), back pain, sciatica (pain extending from lower back down the leg), pain after surgery, fever, dental pain, kidney stone pain, sports injuries, menstrual cramps, tendonitis (inflamed tendons), and other painful conditions (especially where there is inflammation).
  • NSAIDs are also added to many cold and allergy drugs to relieve symptoms such as minor aches and pains, headaches, and fevers.
