Hemolytic Anemia Induced by Infectious Agents: Diagnostic and Treatment approaches

Hemolytic anemia results from the destruction of red blood cells at a faster rate than the body can replace them. Various infectious microorganisms induce this condition through various mechanisms like toxin release, direct invasion of red blood cells and immune responses. The burden of hemolytic anemia requires collaborative efforts to identify risk factors, develop interventions, and control the condition. Diagnosis involves clinical evaluation and laboratory tests like complete blood count, peripheral blood smear examination, serum bilirubin tests, Coombs Test and genetic testing. Advanced molecular diagnostic technologies such as PCR, loop-mediated isothermal amplification (LAMP), gene chips, and high-throughput sequencing offer improved sensitivity, specificity and automation for early pathogen detection in hemolytic anemia cases induced by infectious agents. Treatment options include Rituximab and Bortezomib for immune-mediated hemolytic anemia. Vaccines against Streptococcus pneumoniae, Haemophilus influenzae type b, Plasmodium falciparum and SARS-CoV-2 virus work by reducing pathogen density in the body thus reducing the risk of developing delayed hemolytic anemia. Management strategies should aim to improve diagnostic tools possibly by using diagnostic biomarkers, the development of vaccines, the improvement of treatment options the development of targeted therapies, gene therapies and the re-purposing of existing drugs. Collaboration between healthcare professionals, researchers, and policymakers is crucial to identify risk factors, develop interventions and implementing management strategies.
