[Transmissibility of HIV infections via allogeneic transplants]
Insights
Cialit treatment effectively destroys the human immunodeficiency virus (HIV) in preserved auditory ossicles and fascia. This finding supports the continued use of these allogeneic transplants in middle-ear surgery, ensuring patient safety regarding HIV transmission.
Area of Science:
- Virology
- Transplant Surgery
- Materials Science
Context:
- Human immunodeficiency virus (HIV) can be transmitted through blood, semen, and organ transplants.
- The World Health Organization (WHO) recommends screening donors to prevent HIV transmission.
- Preservation methods for allografts, such as auditory ossicles, are critical for transplant safety.
Purpose:
- To investigate the efficacy of cialit preservation in inactivating HIV in auditory ossicles.
- To determine if the findings extend to other preserved tissues like solvent-dried fascia.
- To assess the safety of using cialit-preserved allografts in light of HIV transmission risks.
Summary:
- Experimental examinations were conducted on HIV-infected auditory ossicles preserved in cialit.
- Results indicate that cialit treatment effectively destroys the HIV virus within the preserved tissues.
- Similar virus-inactivating effects were observed for solvent-dried fascia preserved in the same manner.
Impact:
- The study suggests that cialit preservation is a safe method for allogeneic transplantation of auditory ossicles and fascia.
- It removes objections to the use of these allografts concerning HIV transmission.
- This research supports the continuation of middle-ear allograft transplantations without HIV-related safety concerns.
Abstract:
HIV-infections can be transferred by blood and blood products, semen or organ transplants. For this reason, the WHO recommended a screening of all donors of blood, semen, tissues and organs. Those who belong to high-risk groups should be excluded from donations. If this recommendation should be also applied to cialit preserved auditory aussicles, this would probably mean the end of allogeneic transplantations of middle-ear surgery which are being performed daily. Therefore, we carried out experimental examinations with HIV-infected auditory aussicles in cialit. According to our results, it can be assumed that a virus-destruction takes place via a cialit-treatment. The same applies to solvent-dried fascia as to auditory aussicles which have been preserved in the same way. Consequently, there is no objection to further application of these allogeneic transplants in respect to HIV-infections.
