Clinical Evidence on Polysorbate 80

Kounis Syndrome and Monoclonal Antibody Infusion

Polysorbate 80 has been implicated in allergic reactions during monoclonal antibody infusions. A case study highlighted a patient who developed Kounis syndrome after infliximab infusion, emphasizing the need for early recognition and treatment of such reactions. For more details, see Potential infliximab-induced Kounis syndrome in a patient with metastatic melanoma.

Injection Site Reactions

While specific details are not provided, polysorbate 80 is known to be a component in formulations that can lead to hypersensitivity reactions at injection sites. For further reading, refer to Severe Delayed Hypersensitivity Reaction at Guselkumab Injection Site.

Effects on Skin Microbiome

Research indicates that polysorbate 80 can influence the growth of Cutibacterium acnes, a key bacterium in human skin. High concentrations may enhance bacterial growth, which could relate to skin conditions. More information can be found in the study Effects of common cosmetic ingredients on growth of dominant human skin inhabitant Cutibacterium acnes.
