Summary of "Escalation in mucus cystatin 2, pappalysin-A, and periostin levels over time predict need for recurrent surgery in chronic rhinosinusitis with nasal polyps."

Chronic rhinosinusitis with nasal polyps (CRSwNP) is treated using oral/topical steroids and surgery. Despite maximal medical therapy, some patients remain recalcitrant. Mucus cystatin 2, pappalysin-A, and periostin can predict the presence of CRSwNP and correlate with disease severity. This study was designed to determine whether prospective sampling of these mucus proteins could predict medical failure and the need for revision surgery.

Serum Periostin Level Has Limited Usefulness as a Biomarker for Allergic Disease in 7-Year-Old Children.

Previous studies have used serum periostin levels as a biomarker of Th2-driven inflammatory responses. However, no population-based study has yet examined the association of serum periostin levels wit...

Elevated serum levels of periostin in patients with Allergic Bronchopulmonary Aspergillosis.

Serum periostin levels have been reported to be an indicator of Th2 inflammation in asthmatic patients.

Increased cystatin F levels correlate with decreased cytotoxicity of cytotoxic T cells.

Background Cystatin F is a protein inhibitor of cysteine peptidases, expressed predominantly in immune cells and localised in endosomal/lysosomal compartments. In cytotoxic immune cells cystatin F inh...

Medical and Biotech [MESH] Definitions

A cytastin subtype found at high levels in the SKIN and in BLOOD CELLS. Cystatin A incorporates into the cornified cell envelope of stratified squamous epithelial cells and may play a role in bacteriostatic properties of skin.

An extracellular cystatin subtype that is abundantly expressed in bodily fluids. It may play a role in the inhibition of interstitial CYSTEINE PROTEASES.

A cystatin subtype that has a diverse tissue distribution, target specificity, and functions as an endogenous inhibitor of lysosomal cysteine proteases.

An intracellular cystatin subtype that is found in a broad variety of cell types. It is a cytosolic enzyme inhibitor that protects the cell against the proteolytic action of lysosomal enzymes such as CATHEPSINS.

A neoplastic disease in which the alveoli and distal bronchi are filled with mucus and mucus-secreting columnar epithelial cells. It is characterized by abundant, extremely tenacious sputum, chills, fever, cough, dyspnea, and pleuritic pain. (Stedman, 25th ed)
