Abstract

Background: Although there is no specific therapy for COVID-19, it is recommended that patients with severe SARS-CoV-2 infection are treated with corticosteroids and anti-IL-6 receptor monoclonal antibodies. Both COVID-19 itself and the treatment modalities mentioned above have suppressive effects on the immune system which may lead to an increased susceptibility to other infections. In patients with latent tuberculosis (TB) reactivation of TB infection after recovery from severe COVID-19 has been described. Most of these cases have occurred in parts of the world where tuberculosis is endemic.

Case description: The patient is a female in her 70s who was born and raised in Southeast Asia and has lived in the Netherlands for more than 30 years. She was treated for a severe COVID-19 requiring mechanical ventilation for several weeks and pharmaceutical treatment with corticosteroids and anti-IL-6 receptor monoclonal antibodies (Sarilumab). She recovered well. Two years later she was readmitted with symptoms of a serious pulmonary infection and meningitis. Her condition deteriorated in a short time. An active TB infection was diagnosed. Despite adequate antibiotic treatment and supportive therapy her condition worsened and four days after admission to the ICU she deceased.

Discussion: Reactivation of latent TB after recovery from a severe COVID-19 has been described several times and may occur several months after the SARS-CoV-2 infection. In this case the reactivation presented two years after COVID-19. This case illustrates that long-term follow-up of patients with latent TB that recover from a severe COVID-19 may be indicated.

Learning points: Reactivation of latent tuberculosis infection in patients treated for a severe COVID-19 may occur even two years after recovery from SARS-CoV-2 infection.Most cases of reactivation of tuberculosis after COVID-19 are described in regions where tuberculosis is endemic. However, it may also occur in countries with a relatively low prevalence of tuberculosis infection. The exact incidence of tuberculosis reactivation after COVID-19 is unknown and probably underestimated.A long-term follow-up of patients after severe COVID-19 treated with corticosteroids and/or anti-IL-6 receptor monoclonal antibodies with a history of tuberculosis or patients migrated from countries where tuberculosis is endemic seems to be important.
