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).
Pleural effusion. In some cases, pleurisy causes a build-up of excess fluid around the lungs called pleural effusion. Pleural effusion can result in shortness of breath that gets progressively worse. This is more likely in cases of pleurisy caused by pulmonary embolism or a bacterial infection.
