ADA - Fluid

ADA- Adenosine Deaminase is an enzyme that involves in the metabolism of Purine. It breakdowns the Adenosine of the food we consume and convert it into nucleic acids. ADA plays a vital role in regulating the Immune System of the body. This test measures Adenosine Deaminase in Pleural fluid to diagnose Tuberculosis (TB) or Mycobacterium Tuberculosis.

Why ADENOSINE DEAMINASE ADA-2 test?

CLINICAL INFORMATION :

Adenosine deaminase (ADA -2) deficiency or deficiency of adenosine deaminase – 2 (DADA-2) is associated with systemic inflammation and vasculopathy that affects a wide variety of organs. Clinical manifestation includes recurrent fever, livedoid rash (reticular or racemose), various cytopenias (reduced cell counts), and stroke, immunodeficiency, and bone marrow failure. DADA-2is caused by mutation In ADA-2gene. ADA-1 is an intracellular enzyme protein, while ADA-2 is an extracellular enzyme protein highly expressed by myeloid immune cells such as monocytes, macrophages, and dendritic cells. The function of ADA is to catalyze adenosine (it is one of the four nucleosides which is a building block for DNA and RNA) and also serves as a growth factor (hence the treatment of ADA is TNF inhibitors which reduces vasculitis), moreover ADA functions as intracellular DNA sensor. Thus deficiency of ADA-2 leads to inflammatory phenotype disorders. Adenosine also binds to cell surface receptors on neutrophils causing the formation of neutrophil extracellular traps (NETs). Hence levels of NETs are found in high levels in DADA-2. These NETs cause an inflammatory response from macrophages, thus release excess pro-inflammatory cytokines such as TNFa (TNF alpha). Symptoms of DADA-2 are vasculopathy (Hallmark of DADA-2) along with skin, GIT, kidneys, and neurological manifestations, decreased IgG, IgM, reduced B-cell function, and/or immunodeficiencies, pure red cell aplasia (no synthesis of RBCs due to bone marrow failure along with hepato-splenomegaly).
