There are three main groups of blood cancers: 1. Leukemia. 2. Lymphoma. 3. Multiple myeloma. Leukemia. A diagnosis of leukemia is made when the cells that cause a cancer are found circulating in the bloodstream.ultiple Myeloma. This very complicated blood cancer is caused by the overgrowth in the bone marrow of an immune cell called a plasma cell, which secretes a protein into the bloodstream, called an âM-protein,â that can be detected by a test called an immunoelectrophoresis.
Drugs that induce pemphigus may be categorized into 2 groups: thiol drugs and nonthiol drugs. Thiol drugs are reported most frequently as the culprits of drug-induced pemphigus. They contain a thiol group (-SH) in their chemical structure. Penicillamine, captopril, and enalapril are the thiol drugs most often associated with drug-induced pemphigus.
Back to Top Causes. Pemphigus is an autoimmune disorder. The immune system produces antibodies against specific proteins in the skin and mucus membranes. These antibodies break the bonds between skin cells. This leads to the formation of a blister. The exact cause is unknown. Sometimes pemphigus is caused by certain medications, although this is rare. Medications that may cause this condition include: 1  A drug called penicillamine, which removes certain materials from the blood (chelating agent). 2  Blood pressure medications called ACE inhibitors.
