Four different purified hyaluronidases have been approved for use in the United States, three of animal origin and one recombinant. They are indicated as adjuvants in subcutaneous fluid administration for achieving hydration, for increasing the dispersion and absorption of other injected drugs, or for improving resorption of radiopaque agents, in subcutaneous urography.
Hyaluronidase is widely assumed to facilitate the spread of the bacteria through tissues by breaking down hyaluronic acid, an important component of connective tissue. However, very few isolates of S. pyogenes are capable of secreting active hyaluronidase due to mutations in the gene that encodes the enzyme.
This enzyme is active at an acidic pH and is the major hyaluronidase in plasma. Mutations in this gene are associated with mucopolysaccharidosis type IX, or hyaluronidase deficiency. The gene is one of several related genes in a region of chromosome 3p21.3 associated with tumor suppression.
The fixed-dose combination of pertuzumab, trastuzumab, and hyaluronidase was approved for medical use in the United States in June 2020. [5] [10]The FDA's approval was based on the results of a non-inferiority study in participants with HER2-positive early breast cancer, which demonstrated the fixed-dose combination of pertuzumab, trastuzumab, and hyaluronidase had comparable efficacy and ...
Hyaluronidase-2 is a multifunctional protein, previously thought to only possess acid-active hyaluronan-degrading enzymatic function. In humans it is encoded by the HYAL2 gene. [5] [6] [7] This gene encodes a protein which is similar in structure to hyaluronidases.
It is diagnosed through a combination of a thorough clinical evaluation in which characteristic findings are identified, specialized tests that can detect things like excessive levels of mucopolysaccharides and enzym essays to see if there is a deficiency in the enzyme hyaluronidase. [4]
Microbial hyaluronic acid production refers to the process by which microorganisms, such as bacteria and yeast, are utilized in fermentation to synthesize hyaluronic acid (HA). [1] HA is used in a wide range of medical, cosmetic , and biological products because of its high moisture retention and viscoelasticity qualities. [ 2 ]
Nivolumab/hyaluronidase, sold under the brand name Opdivo Qvantig, is a fixed-dose combination anti-cancer medication used for the treatment of various forms of cancer. [ 1 ] [ 2 ] Nivolumab/hyaluronidase contains nivolumab , a programmed death receptor-1 (PD-1)-blocking monoclonal antibody ; and hyaluronidase , an endoglycosidase . [ 1 ]
