Background
- One of the thrombotic microangiopathies
- Different pathophysiology and treatment from typical hemolytic-uremic syndrome (after STEC diarrhea) and atypical hemolytic-uremic syndrome (though often grouped with aHUS)
- Associated with autoimmune diseases, transplantation, malignancy, infection, cytotoxic mediation, or pregnancy
- Most common associations are with Streptococcus pneumoniae and influenza
- Solid organ transplantation, mostly in the month or months after transplantation but rarely after a year[1]
- Hematopoietic stem cell transplantation, up to months to years after transplant
- Systemic lupus erythematosus[2]
- Multiple solid organ malignancies (usually metastatic) are associated with TMA, though prostate cancer (non-metastatic) appears to favour an HUS-like pattern[3]
- Normal pregnancy[4]
- Drug-induced thrombotic microangiopathy
