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).
Treatments used in pleurisy and pleural effusion focus primarily on the underlying cause. For example, if bacterial pneumonia is the cause, an antibiotic will control the infection. If the cause is viral, pleurisy will resolve on its own. The outcome of pleurisy treatment depends on the seriousness of the underlying disease.
