Abstract

BACKGROUND: Viral contamination of platelet (PLT) concentrates can result in transfusion‐transmitted diseases. A photochemical treatment (PCT) process with amotosalen‐HCl and long‐wavelength ultraviolet light (UVA), which cross‐links nucleic acids, was developed to inactivate viruses and other pathogens in PLT concentrates. STUDY DESIGN AND METHODS: High titers of pathogenic or blood‐borne viruses, representing 10 different families, were added to single‐donor PLT concentrates containing 3.0 × 10 11 to 6.0 × 10 11 PLTs in approximately 300 mL of 35 percent plasma and 65 percent PLT additive solution (InterSol). After PCT with 150 µmol per L amotosalen and 3 J per cm 2 UVA, residual viral infectivity was assayed by sensitive cell culture or animal systems. RESULTS: Enveloped viruses were uniformly sensitive to inactivation by PCT whereas nonenveloped viruses demonstrated variable inactivation. Log reduction of enveloped viruses for cell‐free HIV‐1 was >6.2; for cell‐associated HIV‐1, >6.1; for clinical isolate HIV‐1, >3.4; for clinical isolate HIV‐2, >2.5; for HBV, >5.5; for HCV, >4.5; for DHBV, >6.2; for BVDV, >6.0; for HTLV‐I, 4.2; for HTLV‐II, 4.6; for CMV, >5.9; for WNV, >5.5; for SARS‐HCoV, >5.8; and for vaccinia virus, >4.7. Log reduction of nonenveloped viruses for human adenovirus 5 was >5.2; for parvovirus B19, 3.5‐>5.0; for bluetongue virus, 5.6‐5.9; for feline conjunctivitis virus, 1.7‐2.4; and for simian adenovirus 15, 0.7‐2.3. CONCLUSION: PCT inactivates a broad spectrum of pathogenic, blood‐borne viruses. Inactivation of viruses in PLT concentrates with amotosalen and UVA offers the potential to prospectively prevent the majority of PLT transfusion‐associated viral diseases.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Psoralen derivatives are used in photopheresis of cutaneous T-cell lymphoma and photoinactivation of pathogens in plasma and platelet components.

    “Other applications of psoralen derivatives deal with the photopheresis of cutaneous T-cell lymphoma (156-158) and the photoinactivation of pathogens in plasma and platelet components (159,160).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
