Abstract

Vaccination against the virus responsible for COVID-19 has become a key in preventing mortality and morbidity related to the infection. Studies have shown that the benefits of vaccination outweigh the risks. However, there are concerns regarding serious adverse events of some vaccines, although they are fortunately rare. Here, we report a case of a 47-year-old female from Kathmandu who presented with high grade fever, dry cough and erythematous rash a week after exposure to the Oxford-AstraZeneca vaccine. She had hepatosplenomegaly, persistent leucocytosis, anaemia and thrombocytosis along with markedly raised inflammatory markers. Her tests for infectious causes and haematological malignancies was negative and she showed no response to multiple antibiotics. Finally, she had a dramatic response to steroids with disappearance of fever and normalization of other laboratory parameters. Hence, she was diagnosed with Adult-onset Still’s Disease (AOSD). She was under methotrexate and prednisolone tapering dose and doing well as at time of writing. The trigger for the disease was hypothesized to be the vaccine because of the strong temporal association.

Highlights

  • Adult-onset Still’s Disease (AOSD) is a multisystem autoinflammatory disease characterized by high grade fever, inflammatory arthritis, and an evanescent rash

  • We describe a case of AOSD following administration of the Oxford-AstraZeneca vaccine in Nepal
