  • Once hemolytic anemia is diagnosed, the next step in the workup is to differentiate extravascular from intravascular hemolysis. As mentioned above, splenomegaly is a physical finding that points strongly toward extravascular hemolysis.[thebigl.co]
  • Transfusions of platelets in TTP may make condition worse Urgent use of second and third line treatments in refractory TTP helps prevent complications Patients with DIC should first be stabilized, prior to workup or treatment of underlying causes.[oncologynurseadvisor.com]
  • However, recognizing that a hemolytic process is present is also very important, as this will guide workup and occasionally, specific treatments. References / Further Reading Kelton JG, Chan H, Heddle N, et al. Blood and Bone Marrow Pathology.[emdocs.net]


  • Treatment Treatment is directed at the underlying cause. Iron loss can be remedied with iron replacement therapy for a period of time. References 1. Merck Manual (Home edition): Anemia 2.[nethealthbook.com]

  • Because she had no evidence of cardiovascular decompensation, the only treatment needed was iron replacement.[bloodjournal.org]
  • For severe anemia ineligible for reoperation, recombinant human erythropoietin treatment may diminish or eliminate transfusion requirements.[mhmedical.com]
  • Despite B cells returning to normal 11 months after treatment, infant no 1 remained in clinical remission during follow-up (22 months post treatment).[learningcenter.ehaweb.org]


  • THERAPY, COURSE, AND PROGNOSIS If the anemia is sufficiently severe, the most effective treatment consists of replacement of the prosthesis.[medtextfree.wordpress.com]
  • […] the Rh locus Treatment: Steroids: induce remission in 2/3 of patients If disease refractory to steroid taper, can initiate steroid-sparing immunosuppression Splenectomy: equivalent efficacy to steroids IVIG: only occasionally effective (unlike in ITP) Prognosis[errolozdalga.com]
  • Prognosis of typical and atypical HUS is good with high survival rates with supportive treatment or eculizumab. Kidney function can return to normal when eculizumab is started early. This is the key to try to preserve kidney function.[oncologynurseadvisor.com]
  • Prognosis The prognosis, or outlook, of anemia is often good, depending upon the type and specific cause of the disorder. The severity of anemia, patient’s age, patient’s health, and patient’s compliance with treatment will affect recovery.[phlbi.org]
  • Prognosis AIHA is transient in children following viral infection. Usually chronic in adults with exacerbations and remissions 27. Warm AIHA 28. COLD ANTIBODY IMMUNOHEMOLYTIC ANEMIA.[slideshare.net]

  • […] production and keep up with the loss. 1, 2, 3 Usually HAs are diagnosed through laboratory tests, however, the patient's history and physical examination are crucial as they provide important information about the presence of hemolysis and its probable etiology[ncbi.nlm.nih.gov]
  • Patients admitted to the ICU with different etiology showed symptoms and signs of microangiopathic hemolytic anemia. There were 80 patients (age: 20 - 70 years) and 100 controls in this study. Controls were selected at random from a laboratory.[thejh.org]
  • This possible mechanism should be considered in patients with iron deficiency anemia with no apparent etiology (gastrointestinal bleeding, heavy menses, pregnancy, or hookworm infestation).[thebigl.co]
  • The etiologies of hemolysis often are categorized as acquired or hereditary. Common acquired causes of hemolytic anemia are autoimmunity, microangiopathy, and infection.[aafp.org]

  • This disorder is similar to TTP and HUS in that endothelial cell damage plays a key role in the pathophysiology.[emdocs.net]

  • Causes include RBC membrane abnormalities such as bound immunoglobulin, or physical abnormalities restricting RBC deformability that prevent egress from the spleen. Extravascular hemolysis is characterized by spherocytes.[med-ed.virginia.edu]
  • Prevention A healthy lifestyle, including an appropriate diet, limited alcohol use, and regular medical checkups for blood tests can help to prevent anemia or, for those already diagnosed with the condition, keep it under control.[phlbi.org]
