Understand how AIHA and its subtypes can be diagnosed through a combination of clinical assessment and laboratory tests.

Consequent complement activation can impact the clinical picture and is an emerging target for therapeutic approaches. When a patient presents with anemia, a stepwise approach should be followed.

Initial simple investigations Table 1 will first alert the physician to the suggestion of hemolysis as the cause of the anemia. Although the typical pattern is presented, none of these tests are fully sensitive or specific for hemolysis. For example, liver disease can increase lactate dehydrogenase LDH and reduce haptoglobin.

The bilirubin may be normal with milder hemolysis, and spherocytes are not always visible. Reticulocytopenia can occur in AIHA, secondary to bone marrow infiltration by a lymphoproliferative disorder or to parvovirus B19 infection. This may be caused by immune attack on late-stage erythroid precursors or reflect a lag in marrow responsiveness, but it can sometimes persist and predict a more severe clinical course. There are fewer causes of intravascular hemolysis; therefore, these can be very useful for subsequent investigations Table 2.

Once hemolysis is confirmed, further investigation is needed to establish whether that hemolysis is immune, principally by the direct anti-globulin test DAT. Modified from Hill et al, with permission. After identifying hemolytic anemia with a positive DAT, hopefully obvious causes, such as a delayed transfusion reaction from a recent transfusion, alloimmune hemolysis following solid organ or allogeneic stem cell transplantation, drug-induced immune hemolysis, or hemolytic disease of the newborn, will be quickly identified by clinical assessment.

When considering alternatives, it should be remembered that a positive DAT can occur as a result of other processes, such as passive deposition of antibodies or immune complexes in liver disease, chronic infection, malignancy, systemic lupus erythematosus SLE , renal disorders, and following drug therapies, such as IV Ig or anti-thymocyte globulin.

If no alternative cause is identified, a diagnosis of AIHA can be made. A diagnosis of DAT-negative AIHA can be made following careful exclusion of alternative causes of hemolysis, and confirmation by a sensitive technique where available, and is supported by a response to steroid therapy. A suggested diagnostic pathway for AIHA is shown in Figure 2 , although it is recognized that there are exceptions eg, a low-titer cold antibody can sometimes be clinically significant.

Therefore, a final diagnosis may require synthesis of the clinical picture and advice from a specialist reference laboratory. Diagnostic pathway for AIHA. Adapted from Hill et al with permission. Primary cold agglutinin disease CAD is caused by an underlying lymphoproliferative bone marrow disorder, and its pathophysiology is described elsewhere. IgM binds C1q on the red cell membrane, activating the classical complement pathway but disassociating from the red cells centrally, leading to a DAT that is characteristically positive for only C3d, although a weak positive IgG is sometimes also detected.

This process leads to extravascular removal of C3b-coated red cells by the reticuloendothelial system; however, exacerbations can activate C5, leading to intravascular hemolysis.

Patients with positive screening can then have antibody titers assessed. Cold agglutinin syndrome CAS can be diagnosed in patients with laboratory criteria consistent with a clinically significant cold antibody that occurs in association with secondary disorders, such as infection, SLE, or aggressive lymphoma.

Paroxysmal cold hemoglobinuria PCH usually occurs in children. The hemolysis can be severe and intravascular but is typically transient following infection. PCH is caused by a biphasic IgG antibody that binds to red cells at low temperature and causes complement-mediated lysis as the temperature is increased.

Criteria for the diagnosis of AIHA and its subtypes, as well as definitions of treatment response, have varied among studies. An international consensus on terminology and response criteria would be useful to increase comparability between clinical trials. British guidelines on secondary AIHA have recently been published. A broad strategy is to treat the underlying condition according to best practice. Successful treatment may also improve the AIHA, but that is not always the case because the strength of the association varies.

If the associated condition does not require treatment, AIHA can usually be approached in a similar fashion to primary AIHA, although treatment decisions must be individualized. In patients with active CLL that also requires treatment, combinations, such as rituximab, cyclophosphamide, and dexamethasone RCD ; rituximab, cyclophosphamide, vincristine, and prednisolone R-CVP ; and bendamustine and rituximab BR , appear to be effective. New targeted therapies, such as obinutuzumab, ibrutinib, idelalisib, and venetoclax, could potentially be beneficial for patients with AIHA; however, vigilance is needed because of potential for development of drug-induced immune cytopenias, as previously observed with single agent fludarabine.

Erythropoiesis increases in response to hemolysis, resulting in greater demand for folate. Folic acid is a well-tolerated supplement to prevent a deficiency that could exacerbate the anemia. Without a history of transfusion or pregnancy, the patient is unlikely to have an alloantibody. If anemia is life threatening, transfusion of ABO Rh and K matched red cells may be preferable to waiting for full-compatibility testing. Your reviews of a new store or restaurant were written for businesses you liked, until they were written for advertisements by Google.

Nest and Google are just trying to make sure you have the best energy provider to use with your Nest. In light of all the information Google already has on us, a shallow, knee-jerk reaction to its acquisition of Nest might be, so what? It already knows where we are through smartphone GPS more or less all the time. I can do Google one better: it certainly knows my location from my Wi-Fi router, and it knows the one address I type into Google Maps 95 percent of the time.

Google knows where I live, certainly. Nest made several partnerships with electric companies in that would provide a Nest device and some bill discounts to customers if they were able to lower their power consumption. Vaccines and Preventable Diseases. Section Navigation.
