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).
For example, if the cause of pleurisy is a bacterial infection of your lung (pneumonia), an antibiotic may control the infection. But, for pleurisy due to a viral infection, antibiotics won't be effective. Most viral infections run their course without treatment.
