Medical Case Reports

The  human leukocyte antigen  ( HLA ) genes  encode proteins essential for mounting an immune response.  Immune systems of people with specific HLA types may be better or worse at mounting an immune response and generating antibodies to specific proteins.  HLA-A11  (A11) is one of serotypes with 10.8% frequency in worldwide population. It's most  common in East Asia. One of its variations,  HLA-A*11, has been linked with vaccine-induced  subacute thyroiditis (V-SAT) . This rare transient inflammatory thyroid disease is usually associated with pain and tenderness of the gland, as well as generalized somatic symptoms: from anxieties,  difficulty swallowing, changes in appetite,  malaise and fatigue to  complete prostration for weeks or months if left untreated. HLA-A*11:01:01:01 was found to be significantly associated with the severity of COVID-19.   SAT is the most common thyroid dysfunction following SARS-CoV-2 vacc...

We present two cases following inactivated virus and mRNA vaccines and discuss additional cases of fetal pericardial effusion after maternal COVID-19 vaccination.  A 34-year-old man without any significant past medical history experienced chills and fever 48 hours after inoculation of the Sinopharm vaccine. He had taken Acetaminophen to control the fever; however, on the third day post-vaccination, he developed an atypical pleuritic chest pain for which he was brought to our center. A pan-CT scan with intravenous contrast was performed and showed no findings suggestive of malignant lesions nor any lesions in favor of neoplastic processes. Peritracheal lymph nodes were found with less than 10 mm diameter showing benign reactive lymph nodes. The patient was on nonsteroidal anti-inflammatory drugs and Colchicine with suspicion for pericarditis but no improvement was seen in his condition evaluated by serial echocardiograms. Therefore, a pericardial window was inserted for him and the...
