1.4 Chemical Determination. Proteins are complex, organic compounds composed of many amino acids linked together through peptide bonds and cross-linked between chains by sulfhydryl bonds, hydrogen bonds and van der Waals forces.
Common causes of pleurisy include trauma, postcardiac injury, infection (i.e., viral, bacterial, or parasitic), respiratory illness, caustic exposure (i.e., drug-induced), autoimmune disease, and malignancy (TABLE 1).
Pleurisy used to be a common complication of bacterial infections; since the use of antibiotics, however, rates have dropped substantially. If pleurisy is the result of a bacterial infection, doctors can prescribe antibiotics. If a virus is the underlying cause of pleurisy, no treatment will be given.
