[Double hit; a case report-A history of numerous embolic events during a COVID-19 illness]. / Fallbericht "double hit"­ eine Geschichte mehrerer embolischer Ereignisse im Rahmen einer COVID-19-Erkrankung.

This case report is about an 81-year-old male patient that was brought into the emergency room. Paramedics and an emergency doctor were alarmed because of unconsciousness of unclear origin. Additionally, ST-elevation were detected preclinically, raising the suspicion of an intercerebral hemorrhage; however, the clinical work-up revealed a different and unsuspected cause.

A quadrivalent HPV vaccine induces humoral and cellular immune responses in WHIM immunodeficiency syndrome.

WHIM-syndrome is an inherited immunodeficiency disorder with abnormal susceptibility to human papillomavirus (HPV) infection and diseases. We determined safety and immunogenicity to a quadrivalent HPV vaccine in WHIM-syndrome by detection of HPV-specific antibodies and lymphoproliferation. In virus-like-particle (VLP)-ELISA, a WHIM patient showed antibody titers up to 400 for HPV-6/11/16/18, whereas immuno-competent controls developed titers of 6400-25,600. In pseudovirion assays, the patient's neutralization titers ranged from 20 to 400 to the four HPV vaccine types, while titers of 1600-25,600 were detected in healthy vaccinees. Specific proliferation of PBMC of the WHIM patient to the HPV vaccine was demonstrated. This first report on response to HPV vaccination in WHIM-immunodeficiency highlights that patients with WHIM-syndrome, and probably other immunodeficiencies, may benefit from HPV immunoprophylaxis.
