3.3. Clinical and
demographic characteristics
The 17 included studies described a total of 17 patients with: age
groups, gender distribution and time to onset of symptoms described
separately for each disease. history/comorbidities, test COVID-19, type
of COVID-19 vaccine, dose, symptoms, and treatment were evenly
distributed. Most cases were associated with Pfizer-BioNTech vaccine
(mRNA) with 64.71 %, followed by Modern (mRNA) (11.76 %), BBIBP-CorV
(Sinopharm) (11.76 %) and Johnson & Johnson / Jassen vaccine (Viral
Vector) (11.76 %), most cases associated with the first dose (52.94
%). Among the symptoms, acute abdominal pain was present in almost all
studies (82.35 %), other studies reported Epigastric pain (17.64 %).
No death was reported in any study, all patients recovered, and most
were discharged in the following weeks. Treatment was medical in most
cases (88.34 %) and only one (11.76 %) required surgical treatment.
The clinical and demographic characteristics are shown in detail inTable 2 .
