Abstract The safety of the injection therapy has to be secured including that of the injection itself as well as that of the equipment used for injection, i.

The contamination of insoluble particulate matter ascribed to coating of silicone oil over disposable syringe is being solved by the development of syringe using fluoro-resin laminated rubber. In the case of blood administration set and blood bag system, there are some in which the solvent used for adhesion has been eluted. Further, the relationship between the quality of materials of administration set and the adsorption of drugs has become clear.

In the case of plastic bag, that made of polyethylene does not adsorb drugs so much and the formation of insoluble particulate matter is a little.

Glass syringes were used with stainless steel needles and uncoated plunger stopper. Surface of borosilicate glass is hydrophilic, whereas the COP plastic surface is rather hydrophobic, suggesting that the difference in surface hydrophobicity is insignificant for the aggregates formation. The FDA also is working with federal, state, and local law enforcement officials to inform them of these occurrences and to help prevent unlicensed providers from harming people through the injection of silicone and other unapproved materials.

Intravenous silicone oil safety. Associated Data

In contrast, small amounts of dimers and oligomers were detected by SEC for silicone oil-lubricated glass syringe samples. In general, there was a reasonable agreement between SEC and AUC-SV results regarding detected oligomeric species and their respective amounts as reported previously. In agreement with the results of previous studies, the levels of aggregates were slightly higher when measured by AUC-SV compared with the SEC estimates.

Overall, for both protein formulations, the loss of monomer for samples in silicone oil-lubricated syringes is clearly indicated by both SEC and AUC-SV. The results of particle counting obtained by RMM are shown in Figure 2. On the basis of different buoyancy, protein particles and silicone oil droplets were discriminated and counted separately. PBS-formulated abatacept samples showed similar content of protein particles in polymer and glass SOF syringes, which were lower compared with samples in silicone oil-lubricated syringes Fig.

In the abatacept acetate buffer formulation, particle counts were similar between silicone oil-lubricated and SOF syringes in the range 0. Results of particle counts by RMM for the abatacept PBS formulation a , abatacept acetate buffer formulation b , adalimumab PBS formulation c , and adalimumab acetate buffer formulation d.

Concentrations of protein particles determined by MFI are shown in Figure 3 and total particle counts are summarized in Suppl. Tables S1 and S2. For each protein formulation, the algorithm that allows discriminating silicone oil droplets from total particle counts was developed. Samples from SOF syringe filled with the protein formulation and silicone oil-lubricated syringe filled with the respective formulation buffer were subjected to MFI analysis to derive respective representative profiles of protein particles and silicone oil droplets.

We found that circularity is an appropriate parameter that can be used to discriminate between protein particles and silicone oil droplets. The mean values of the confidence intervals for protein particles and silicone oil droplets were used as a cutoff value Suppl. Table S3. Concentrations of protein particles determined by MFI for the abatacept PBS formulation a , abatacept acetate buffer formulation b , adalimumab PBS formulation c , and adalimumab acetate buffer formulation d.

Considerably larger amounts of particles were detected for silicone oil-lubricated syringes samples. In agreement with MFI results for the abatacept, adalimumab formulations showed similar particles concentrations for SOF syringes samples and higher levels of particles were detected for silicone oil-lubricated samples.

The loss of native protein upon particles formation is essentially undetectable as cumulative mass of the protein in particles only comprises a few micrograms. Figure S2. Layers of adsorbed protein form films that are suspected to serve as a major source of protein particles upon rupture. Agitation of protein solutions in the presence of COP beads with no headspace did not induce aggregate formation data not shown.

Thus, the disruption of the layers of adsorbed protein followed by the release of the torn film pieces into bulk solution phase can be attributed to the air bubble in the headspace as suggested previously. Microflow imaging results indicated that at least with the proteins and syringes used in the present study, no significant differences in particle levels were observed between SOF glass and polymer-based syringes.

During agitation, the dissociation of adsorbed protein from the surface was caused by the air bubble, and after agitation completion the layers of adsorbed protein were removed when the solution was pushed through the syringe barrel with the plunger to collect samples for the further analyses. Tables S4 and S5. These results suggest that a correlation exists between silicone oil levels and amounts of particles formed in solution.

In the present study, the amount of silicon oil used to lubricate the inner surface of syringe was about 0. Further studies may be needed to evaluate the effect of different silicone oil levels applied to the different syringe barrel material. Table S1. Similarly, for adalimumab formulations prefilled in silicone oil-lubricated syringes, amounts of particles were larger in acetate buffer formulation compared with PBS formulation Suppl.

Table S2. Interestingly, the increased protein particles counts in acetate buffer formulation were consistent with higher amounts of silicone oil droplets detected relative to PBS formulation, again suggesting a positive correlation between the amount of silicone oil droplets and particle counts. These observations indicate that acetate buffer promotes detachment of silicone oil droplets from the inner surface of syringe, which in turn leads to increase in the number of particles.

For the adalimumab solutions prefilled in SOF syringes, no soluble aggregates were detected and particle counts were similar for different formulations. In all cases, samples from SOF glass and polymer-based syringes had similar amounts of insoluble aggregates, soluble aggregates, and subvisible particles.

Silicone oil lubrication caused the formation of insoluble aggregates in samples other than the adalimumab formulated in acetate buffer, and the effect was more pronounced in case of silicone oil-lubricated glass syringes compared with silicone oil-lubricated polymer syringes.

For the same lubricated syringe type, particle counts were higher in acetate buffer formulations than in PBS formulations. The highest particles counts were consistently observed in silicone oil-lubricated glass syringes, which was associated with larger silicone oil amounts detected in silicone oil-lubricated glass syringes compared with polymer-based syringes.

Surgery to remove large-scale injectable silicone may present additional risks and serious complications, and may not entirely rid the body of the silicone. Multiple medical and surgical interventions are sometimes needed to treat symptoms years after initial injection; even then, patients may continue to experience ongoing pain, infection, and scarring and permanent disfigurement requiring ongoing treatment.

FDA Actions The FDA is monitoring reports of adverse events associated with the use of injectable silicone and other unapproved materials and will update the public if significant new information becomes available.

The FDA has investigated numerous criminal cases related to injectable silicone, which have resulted in successful prosecutions. The FDA also is working with federal, state, and local law enforcement officials to inform them of these occurrences and to help prevent unlicensed providers from harming people through the injection of silicone and other unapproved materials.

Reporting Problems to the FDA Prompt reporting of adverse events can help the FDA to identify and better understand the risks associated with these products. If you suspect or experience a problem with injectable silicone or a dermal filler, we encourage you to file a voluntary report through MedWatch , the FDA Safety Information and Adverse Event Reporting program. Health care personnel employed by facilities that are subject to the FDA's user facility reporting requirements should follow the reporting procedures established by their facilities.

GOV , , or Recommendations for Consumers: Injectable Silicone Do not get injectable silicone or any type of filler material for large-scale body contouring or enhancement.

The FDA is aware of serious medical problems and multiple deaths associated with such use. See the Summary of Problem and Scope section above for more information. Know that there are no FDA-approved injectable silicone products for body contouring, or to increase the size of areas such as the breasts or buttocks. Seek medical attention immediately if you experience problems such as difficulty breathing, chest pain, signs of a stroke including sudden difficulty speaking, numbness or weakness in your face, arms, or legs, difficulty walking, face drooping, severe headache, dizziness, or confusion after receiving injectable silicone, as it may be a life-threatening situation.

Be sure to let your health care provider know you have had silicone injections. Seek appropriate medical care, such as from a licensed board-certified plastic surgeon, if you have had silicone oil injections and are experiencing side effects such as pain, hardening of the skin, lumps, or infections.

If you believe you have been offered or have received injectable silicone for body contouring from an unlicensed provider, you are encouraged to use the FDA website to report suspected criminal activity. If you are considering a body enhancement or body contouring procedure, only see a licensed health care provider who has appropriate training and experience e. Recommendations for Consumers: FDA-Approved Dermal Fillers Before deciding to have any sort of filler injections, talk with your licensed health care provider about appropriate treatment injection sites and the risks associated with the procedure as well as the product being injected.

Know that FDA-approved dermal fillers are not indicated for everyone. Only get FDA-approved dermal fillers injected by licensed health care providers. These health care providers should have appropriate training and experience and should be knowledgeable about the anatomy at and around the injection site. When getting any sort of injectable filler, ask your health care provider for the FDA-approved product brochure and patient labeling.

Ask questions and read and discuss the patient labeling for the specific filler you are receiving. Check the FDA website on approved dermal fillers prior to receiving treatment to confirm that the product has been approved by the FDA.

Recommendations for health care providers Be aware that injectable silicone is not approved for large-scale body contouring or enhancement, and serious adverse events have been reported.

Product Silicone oil is a liquid polymer of siloxane that can be used in products such as lubricants and caulking materials. The U. Food and Drug Administration FDA has not approved injectable silicone silicone oil for large-scale body contouring or enhancement. Injectable silicone is different from silicone oil used in small amounts in the eyes and from the silicone used to fill FDA-approved breast implants.

The only FDA-approved injectable silicone is silicone oil used for specific intraocular ophthalmic inside the eye use.

Purpose The FDA is alerting the public and health care providers that injectable silicone is not approved to enhance or augment the body. Such use can lead to ongoing pain, infections, and serious injuries, such as scarring and permanent disfigurement, embolism blockage of a blood vessel , stroke, and death.

The FDA is aware that some injectors have falsely told consumers they were receiving an FDA-approved dermal filler, but consumers were instead injected with silicone. Injectable silicone is permanent, with side effects that can occur right after the injection and up to years after treatment.

Silicone spreads and migrates easily inside the body, which may worsen adverse events and make surgical attempts to remove the silicone oil more difficult or impossible.

Silicone, when injected into areas with many blood vessels such as the buttocks, can travel to other parts of the body and block blood vessels in the lungs, heart, or brain. This can result in permanent damage to those tissues and lead to stroke or death. Surgery to remove large-scale injectable silicone may present additional risks and serious complications, and may not entirely rid the body of the silicone.

Multiple medical and surgical interventions are sometimes needed to treat symptoms years after initial injection; even then, patients may continue to experience ongoing pain, infection, and scarring and permanent disfigurement requiring ongoing treatment. FDA Actions The FDA is monitoring reports of adverse events associated with the use of injectable silicone and other unapproved materials and will update the public if significant new information becomes available.

Recommendations for health care providers Be aware that injectable silicone is not approved for large-scale body contouring or enhancement, and serious adverse events have been reported. The FDA recommends that you do not inject silicone to achieve breast, muscle, or buttocks enhancement.

Be aware that: The use of silicone oil outside intraocular ophthalmic use is not approved by the FDA. Silicone injections used for body enhancement have resulted in serious injuries or death. When treating patients after injections for body contouring, the type of material used may be unknown. When treating patients who have received silicone injections, the material injected may migrate during revision surgery, which may worsen adverse events and make attempts to remove the injectable silicone oil difficult, incomplete, or impossible.

Educate health care facility staff on how to quickly identify and assist patients who report signs and symptoms of complications from injectable silicone. Staff must understand how to instruct patients to receive appropriate medical care if a serious adverse reaction occurs such as difficulty breathing or signs of a stroke including sudden difficulty speaking, numbness or weakness in the face, arms, or legs, difficulty walking, face drooping, severe headache, dizziness, or confusion during or shortly after a procedure.

Discuss the benefits and risks of FDA-approved options for body contouring with patients. Report to the FDA and, if applicable, the manufacturer if you become aware of a patient experiencing an adverse event associated with injectable silicone.
