Article Synopsis
- A recent review examined the link between COVID-19 vaccination and the development of aplastic anemia (AA) in patients infected with SARS-CoV-2, analyzing 26 research studies involving 53 cases.
- The review highlighted diverse causes of AA and discussed potential new factors, including SARS-CoV-2 and COVID-19 vaccines, while addressing a gap in current medical knowledge.
- Although a direct mechanism connecting AA with these factors isn’t confirmed, the review explored possible biological mechanisms behind this association to enhance understanding in medical practice.
Article Synopsis
- - Kounis syndrome (KS) involves acute coronary syndrome triggered by an anaphylactic reaction and is often missed in diagnoses; new causes for it are being recognized.
- - A review of 190 studies revealed that most patients were male, with an average age of 54.4 years, and common issues included hypertension, diabetes, and chest pain.
- - KS commonly results from drug use (especially antibiotics) and has a calculated incidence rate of 11.12 per 1000 people, with a mortality rate of 7.47%, but 86.92% of patients showed positive outcomes after treatment.
Aplastic Anemia Following COVID-19 Vaccination: A Systematic Review of Case Reports and Case Series.

Aplastic anemia (AA) is the prototypical bone marrow failure syndrome due to the destruction of hematopoietic stem cells by cytotoxic T cells. According to case reports, vaccines could lead to the development of AA. We conducted the present systematic review to evaluate cases of AA following vaccination against coronavirus disease (COVID-19).

- This study systematically reviews case reports related to acute abdomen following COVID-19 vaccination to explore potential associations and patient characteristics.
- A total of 17 cases were identified, most frequently linked to the Pfizer-BioNTech vaccine, with conditions like acute pancreatitis and appendicitis observed post-vaccination.
- The findings suggest acute abdomen is a rare complication, mostly treatable, and emphasize the need for further research to understand the mechanisms behind these occurrences.
Objective: Vaccination against SARS-CoV-2 reduced morbidity and mortality rates due to COVID-19 worldwide. However, several adverse effects have been documented and of great interest such as Systemic Lupus Erythematosus (SLE). The aim of the present study was to perform a systematic review of case reports and case series describing the development of SLE following COVID-19 against vaccination.
