Revisión del síndrome post-COVID-19 asociado a efluvio telógeno agudo

BACKGROUND: The coronavirus disease 2019 (COVID-19) has impacted our society in numerous aspects. As of November 2022, around 640 million SARS-CoV-2 infections have been confirmed worldwide. OBJECTIVE: To know and compare the literature described about the association of COVID-19 with the development of telogen effluvium (TE). MATERIAL AND METHODS: A review of the literature limited to case reports and described bibliography of acute TE associated with post-COVID-19 syndrome was carried out. Various contributions on this entity are shown so far. RESULTS: After the analysis of the selected studies, carried out in Spain, Italy, Iraq and the USA, a greater presence of telogen effluvium was identified in patients with COVID-19 diagnosed by confirmatory PCR test, being mainly female, aged over 40 years, with outpatient care and topical treatment. CONCLUSIONS: The analysis shows that patients with COVID-19 are exposed to multiple predisposing factors for the development of TE; about 1 in 10 patients suffering from acute TE had some subclinical infection by the virus.
