What Is the Current Recommended Treatment for Lupus Nephritis?
Lupus nephritis is kidney disease that is caused by lupus. To start, it must be understood that there are many forms of kidney disease that are referred to as lupus nephritis. Each form is distinguished by characteristic patterns of abnormalities as defined by a kidney biopsy. (A biopsy is the removal of a sample of tissue for microscopic examination.) Typically, the findings on a kidney biopsy of a lupus patient are classified according to the appearance of the tissue and immune abnormalities seen under the microscope.
In addition to the numerous unique forms of lupus kidney disease, other types of kidney diseases that are not from lupus can sometimes occur in a patient with lupus. While treatment for lupus nephritis can sometimes be initiated without a kidney biopsy, more often, a biopsy is done before starting treatment. Thus, when the blood tests and the overall state of the lupus disease so require, the biopsy can define the cause of the kidney disease when it is in question. The biopsy can also guide treatment when it demonstrates the presence of such severe kidney damage that a favorable response to potentially toxic medications is unlikely.
Any particular form of lupus nephritis has a variety of treatments available that are effective. Moreover, the treatment for individual patients with lupus nephritis depends not only on their own particular form of kidney disease, but also on the manner in which lupus is affecting other areas of their body, their overall health, and their personal wishes. Also, medical control of conditions that could further injure the kidneys, such as elevated blood pressure and medication-induced kidney toxicity, is essential.
