NCT05736354

Brief Summary

Bacterial biofilms cause implant failures, chronic inflammation, and immune polarization. The study investigates the possible role of bacterial biofilm as a factor in the etiology of Breast Implant Illness. Three patient cohorts will be studied (A) Subjects with breast implant with BII manifestations (B) Subjects with breast implants without BII manifestations (C) Subjects without breast implants who underwent breast surgery procedure. Blood, surgically discarded tissue, implants, and associated capsules will be collected through this protocol.

Outcome Measures

Primary Outcomes (4)

  • Presence of Biofilm in Breast Tissue

    During a clinically scheduled breast surgery, breast tissue specimens will be taken from surgically discarded tissue. The specimens from both breast implant subjects and control subjects (those undergoing breast surgery for a reason other than implant removal) will be analyzed to determine the presence of bacterial biofilm.

    Through study completion, an average of 1 year

  • Analysis of host-biofilm interaction mediated oxylipins from blood

    Prior to a clinically scheduled breast surgery, 20 milliliters of blood will be collected during the pre-operative surgical preparations. The blood samples from both breast implant subjects and control subjects (those undergoing breast surgery for a reason other than implant removal) will be analyzed for host-biofilm interaction mediated oxylipins.

    Through study completion, an average of 1 year

  • Cytokine analysis will be performed on breast tissue

    During a clinically scheduled breast surgery, breast tissue specimens will be taken from surgically discarded tissue. The specimens from both breast implant subjects and control subjects (those undergoing breast surgery for a reason other than implant removal) will undergo cytokine analysis.

    Through study completion, an average of 1 year

  • Analysis of host-biofilm interaction mediated oxylipins from breast tissue

    During a clinically scheduled breast surgery, breast tissue specimens will be taken from surgically discarded tissue. The specimens from both breast implant subjects and control subjects (those undergoing breast surgery for a reason other than implant removal) will undergo oxylipin analysis.

    Through study completion, an average of 1 year

Secondary Outcomes (1)

  • CD4+ Immunological Activation due to Host Implant Interaction

    Through study completion, an average of 1 year

Study Arms (3)

BII Subjects

Subjects with breast implants having BII manifestations.

Non-BII Subjects

Subjects with breast implants with no reported BII symptoms.

Subjects without Breast Implants

Subjects without breast implants.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

The study population focuses on females, ages 18 years or older, that are either undergoing removal of breast implants or undergoing breast surgery. Participants must be willing to comply with protocol instructions and possess the mental capabilities to understand the procedures, risks, and benefits of the study. Additionally, participants that are pregnant will not be eligible for participation. Lastly, participants that are deemed immunodeficient or currently taking immunosuppressive medications will be ineligible for participation.

You may qualify if:

  • Age greater than or equal to 18 years
  • Undergoing removal of breast implant
  • Willing and able to comply with protocol instructions
  • Age greater than or equal to 18 years
  • Undergoing breast surgery
  • Willing and able to comply with protocol instructions

You may not qualify if:

  • Individuals who are deemed unable to understand the procedures, risks, and benefits of the study, (i.e., unable to provide informed consent)
  • Pregnant females
  • Immunodeficiency (HIV/AIDS, SCID)
  • Currently on immunosuppressive medications
  • Prisoners

Retention: SAMPLES WITH DNA

Surgically discarded samples (implants, associated capsule, and tissue). For control participants, adipose tissue will be collected which will be removed during implant placement. 20 mL of blood will be collected at the time of pre-operative surgical preparation.
