Final answer:
Complications of treatments like immunotherapy include hypersensitivities such as immediate, delayed, and autoimmune reactions, in addition to the risk of iatrogenic and nosocomial diseases.
Step-by-step explanation:
Complications of Immunotherapy Treatments
Reactions that may happen during or after a treatment are known as hypersensitivities and can range from mild to severe. These reactions are maladaptive immune responses towards harmless foreign substances or self antigens after tissue sensitization. Common forms of hypersensitivities include immediate reactions, such as anaphylaxis, delayed reactions like contact dermatitis or tuberculin reactions, and autoimmunity conditions, such as type I diabetes mellitus and rheumatoid arthritis. Another concern in medical treatment are iatrogenic diseases, which are contracted as a result of a medical procedure. Nosocomial diseases, contracted in hospital settings, also pose a significant threat due to factors like improper sterilization and the prevalence of drug-resistant bacteria.
