BACKGROUND
Henoch-Schonlein purpura (HSP) is an IgA-mediated systemic small-vessel vasculitis (IgAV) that typically presents with a variable tetrad of symptoms. HSP if often preceded by respiratory tract infections, vaccinations, drugs or malignancies. During the recent COVID-19 pandemic multiples cases of HSP have been described after both infection and vaccination for SARS-CoV2. This study aims to perform a systematic review of literature and describe an additional complicated case of de-novo HSP appeared after the administration of the third dose of a mRNA-SARS-CoV2 vaccination.
METHODS
Electronic bibliographic research was performed to identify all the original reports describing cases of de-novo HSP or IgAV appeared after respiratory infection or vaccine administration for SARS-CoV2. We included all case series or case reports of patients who respected our inclusion and exclusion criteria.
RESULTS
Thirty-eight publications met our pre-defined inclusion criteria, for an overall number of 44 patients. All patients presented with palpable purpura variable associated with arthralgia, abdominal pain or renal involvement. Increased levels of inflammation markers, mild leukocytosis and elevated D-dimer were the most common laboratory findings. Up to 50% of patients presented proteinuria and/or hematuria. Almost all skin biopsies showed leukocytoclastic vasculitis, with IgA deposits at direct immunofluorescence in more than 50% of cases.
CONCLUSIONS
Our results suggest that the immune response elicited by SARS-CoV2 vaccine or infection could play a role in the development of HSP. Current research suggests a possible role of IgA in immune hyperactivation, highlighted by early seroconversion to IgA found in some COVID-19 patients who develop IgA vasculitis.

Adult-onset Still's Disease (AOSD) is a systemic inflammatory condition, mainly characterized by high spiking fevers, leukocytosis, skin rash, arthralgia and myalgia. Liver involvement is a frequent feature, usually presenting with hepatomegaly and mild liver enzymes abnormalities, which usually normalize after treatment with anti-inflammatory or immunomodulatory drugs given for AOSD. Although uncommon, the onset of severe acute hepatitis and even of life-threatening liver failure is possible and requires a prompt diagnosis and an aggressive therapy and, in some cases, an emergency liver transplantation. The differential diagnosis of the cause of the liver injury can be very challenging in these patients. We reviewed the charts of all consecutive patients admitted for acute hepatitis, between January 2019 and December 2019, to the unit of Gastroenterology and Hepatology, Molinette Hospital, Turin, Italy, searching for episodes AOSD-related. In this period, 21 cases of acute hepatitis were recorded with one among them diagnosed as due to AOSD. The incidence was 5% (1/21). This patient was a woman with a recent diagnosis of AOSD who developed a severe acute seronegative biopsy-proven autoimmune hepatitis. She was successfully treated with high-dose methylprednisolone, with a full and stable recovery from the liver injury. We discussED the incidence, etiology, pathophysiology, diagnosis, and standard of treatment in the clinical management of AOSD with a special attention and a systematic review on the available therapies for severe liver involvement associated with AOSD.
