The following information was reported: SERUM FERRITIN DECREASED (non-serious) with onset 29Mar2021, outcome "unknown", described as "Low ferritin (9 ng/ml)"; HAEMORRHAGE (medically significant) with onset 2021, outcome "not recovered", described as "Bleeding; continuous to bleed heavy"; VAGINAL DISCHARGE (non-serious) with onset 2021, outcome "unknown", described as "Increased vaginal discharge"; PALPITATIONS (non-serious) with onset 2021, outcome "unknown"; UTERINE LEIOMYOMA (non-serious) with onset 2021, outcome "unknown", described as "Ultrasound pelvis showed 2 fibroids minimum 1.5x1.1x1.4"; CERVICAL POLYP (non-serious) with onset 15Jul2021, outcome "unknown", described as "Cervical polyp 0.8 x 0.6 x 0.5; benign result polyp; chromic, inflammatory reactive epithelial change"; ANTINUCLEAR ANTIBODY POSITIVE (non-serious) with onset 14Sep2021, outcome "unknown", described as "ANA positive (10.65 mg/l)"; CANDIDA TEST POSITIVE (non-serious) with onset 14Sep2021, outcome "unknown", described as "Candida IgG positive (13%)"; EPIPLOIC APPENDAGITIS (medically significant) with onset 20Oct2021, outcome "recovered" (Jan2022), described as "Epiploic appendages; epiploic appendicitis; severe abdominal pain". The patient underwent second vaccination on 12Jan2021 and experienced continuous heavy bleeding. Laboratory tests checked on 24Mar2021. On and off palpitation and bleeding, doctors continued to monitor laboratory tests and rule out other issues experienced - other symptoms like increased vaginal discharge and (illegible) blood checked DVC (unspecified) to heavy bleeding. This was positive. Antifungals started. Bleeding continued and abdominal pain extreme prompting ultrasound pelvis and CT abdomen (Sep2021 to Oct2021); pelvis which showed 2 fibroids minimum 1.5x1.1x1.4 and show 2x1.8x2 and epiploic appendages. They continued to monitor ferritin/CRPs and multiple follow-up appointments. The patient underwent other laboratory tests and procedures: Antinuclear antibody (0-3): (14Sep2021) 10.65 mg/l; Blood test: (24Mar2021) DVC to heavy bleeding; Candida test (15-55): (14Sep2021) 13 %; Computerised tomogram abdomen: (24Oct2021) Hybrids x 2 intramuscular submucosal, notes: Spreading of that exposed appendicitis; C-reactive protein (0-3): (15Jul2021) 8.68 mg/l, notes: High; C-reactive protein (0-10): (29Mar2021) 5 mg/l; Full blood count: (29Mar2021) Normal; Gynaecological examination: (15Jul2021) Cervical polyp 0.8 x 0.6 x 0.5, notes: Benign result polyp; chromic, inflammatory reactive epithelial change; Hammer strainer (0-14.5): (29Mar2021) 6.5 v/mol/L; Serum ferritin (15-150): (29Mar2021) 9 ng/ml, notes: Low; (29Dec2021) 12 ng/ml; Ultrasound pelvis: (24Oct2021) Hybrids x 2 intramuscular submucosal, notes: Spreading of that exposed appendicitis. The event "epiploic appendages; epiploic appendicitis; severe abdominal pain" required emergency room visit. All events required physician office visit. Therapeutic measures were not taken as a result of epiploic appendagitis. Therapeutic measures were taken as a result of haemorrhage, palpitations, vaginal discharge.; Sender's Comments: The causal relationship between BNT162b2 and the events epiploic appendagitis and haemorrhage cannot be excluded as the information available in this report is limited and does not allow a medically meaningful assessment. This case will be reassessed once additional information becomes available.
