Immune-mediated hemolytic anemia (IMHA) in cats - part 1: a review
Bibliographic record
Abstract
In contrast to dogs, immune-mediated hemolytic anemia is rarely seen in cats and occurs most often secondary to an underlying infectious, neoplastic or inflammatory process.Clinical symptoms are often vague and are caused by severe anemia and the effect of hypoxia on organ systems.Laboratory abnormalities in cats with IMHA are comparable to those seen in dogs, with the exception of spherocytes, which are difficult to identify in cats.The diagnosis is based on hemolytic anemia in combination with a positive 'true' autoagglutination and/or a positive Coombs test.A search for underlying causes should always be performed and, because infections with hemotrophic mycoplasma species are the most important underlying cause for IMHA in cats, a polymerase chain reaction test to detect these bacteria should be carried out.Treatment consists of immunosuppressive drugs, providing oxygen-carrying solutions, treating underlying causes and supportive care.In cats, IMHA carries a better prognosis than in dogs, although relapses are seen in equal frequency. SAMENVATTINGImmuungemedieerde hemolytische anemie (IMHA) komt zelden voor bij katten en ontstaat meestal secundair aan onderliggende infectieuze, tumorale of inflammatoire processen.De klinische symptomen van IMHA zijn meestal vaag en worden veroorzaakt door erge anemie met secundair hypoxie van organen.De bevindingen bij laboonderzoek zijn vergelijkbaar met deze die gezien worden bij honden, met uitzondering van de sferocyten, die bij katten moeilijk te identificeren zijn.De diagnose is gebaseerd op een combinatie van hemolytische anemie met een positieve 'echte' autoagglutinatie-en/of coombstest.Verder onderzoek naar onderliggende oorzaken is steeds noodzakelijk.Aangezien infecties met hemotrofe mycoplasmen de belangrijkste oorzaak van IMHA bij katten zijn, is het uitvoeren van een PCR-test ter detectie van deze bacterie aangewezen.De behandeling bestaat uit het behandelen van onderliggende ziekten, het toedienen van immunosuppressieve geneesmiddelen en een ondersteunende behandeling met ondermeer bloedtransfusies.Katten met IMHA hebben een betere prognose dan honden met deze ziekte, hoewel het percentage patiënten dat hervalt, gelijk is voor beide diersoorten.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
