Causes that may contribute to the development of<unk>  are: immunosuppression (especially for organ transplantation, e.g. with tacrolimus), severe infection and/or sepsis, chemotherapy, autoimmune disease, and pre-eclampsia. High blood<unk> sure is often<unk> ent. Similarly, the majority of people with<unk>  have an impaired kidney function, and 21% are receiving regular hemodialysis. In<unk>  related to medications, there may be an interval of weeks to months between the initiation of the treatment and the development of<unk> . After a hematopoietic stem cell transplantation (bone marrow transplant) the risk of<unk>  is approximately 8%, whereas the risk is lower (0.4-6%) after a solid organ transplant. The following autoimmune conditions have been found to be associated with<unk> : thrombotic thrombocytopenic purpura (TTP), primary sclerosing cholangitis (PSC), rheumatoid arthritis (RA), Sjögren<unk> , polyarteritis nodosa (PAN), systemic sclerosis, systemic lupus erythematosus (SLE), granulomatosis with polyangiitis (GPA), Crohn's disease and neuromyelitis optica (NMO), as well as hemolytic-uremic<unk>  (HUS). A number of other associations have also been reported, including some other groups of medications, blood transfusion, elevated calcium levels, decreased magnesium levels, postpartum cerebral angiopathy, and drugs of abuse (cocaine and amphetamine). It has been suggested that<unk>  is identical or closely related with hypertensive<unk> , the<unk> ence of neurological symptoms in those with a hypertensive emergency.
