Summary
Drug-induced immune hemolytic anemia (DIIHA) can lead to serious complications. This review identifies implicated drugs, antibody production mechanisms, and diagnostic methods for DIIHA, noting increasing drug involvement.
Area of Science:
- Hematology
- Immunology
- Pharmacology
Background:
- Drug-induced immune hemolytic anemia (DIIHA) is a significant clinical concern.
- Serious complications frequently arise from DIIHA.
Purpose of the Study:
- To identify drugs causing DIIHA.
- To elucidate mechanisms of drug-induced antibody production.
- To outline methods for identifying causative agents.
Main Methods:
- Comprehensive literature review of Pubmed and Scholar databases.
- Inclusion of all English language reports and cross-references.
- Analysis of clinical and serological studies.
Main Results:
- Two antibody types identified: drug-dependent and drug-independent.
- Mechanisms include complement-mediated intravascular and Fc-mediated extravascular hemolysis.
- Over 130 drugs implicated, though data can be incomplete.
Conclusions:
- The number of drugs causing DIIHA is rising.
- Most drugs cause DIIHA in isolated cases.
- Newer cephalosporins, diclofenac, oxaliplatin, and fludarabine are frequently implicated.

01:01Hypersensitivity Reactions: Cytolytic Reactions
Type II hypersensitivity involves IgG and IgM antibodies targeting cell surface antigens, leading to cell destruction. This can occur through complement activation, antibody-dependent cell-mediated cytotoxicity (ADCC), or acting as opsonins for phagocytosis. When excessive, these reactions cause significant tissue damage.Drug-induced hemolytic anemia is a common example, where drugs like penicillin or cephalosporins bind to red blood cells, forming drug-protein complexes. These complexes...
01:30Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
01:25Immunodeficiency Diseases
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

01:16Drug toxicity: Idiosyncratic Reactions
Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...
01:27Allergic Drug Reactions
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...
01:19Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
