The patient underwent the following laboratory tests and procedures: Biopsy: (unspecified date) mild ileitis; Blood albumin: (unspecified date) 3.0 g/dl; Blood calcium: (unspecified date) 7.5 mg/dl; Blood glucose: (unspecified date) 136 mg/dl; Blood immunoglobulin A: (unspecified date) 56.7 g/l; Blood immunoglobulin G: (unspecified date) 94.1 g/l; Blood osmolarity: (unspecified date) 274.3 mmol/L; Blood potassium: (unspecified date) 3.0 mEq/l; Blood sodium: (unspecified date) 129 mmol; Bone densitometry: (unspecified date) bones are back to normal; C-reactive protein: (unspecified date) 60 mg/l; Immunology test: (unspecified date) 40 ng/ml; Haemoglobin: (unspecified date) 7.0 g/dl; Drug trough level: (unspecified date) 2.7, notes: mcg/ml; Mean cell volume: (unspecified date) 85, notes: fl; Activated partial thromboplastin time: (unspecified date) 36 seconds; Computerised tomogram: (unspecified date) mesenteric inflammation, dilation of biliary tree; Prothrombin time: (unspecified date) 16 seconds; Protein total: (unspecified date) 5.8 g/dl; Weight: (unspecified date) 10 lbs; (01Jun2022) 10 lbs. Clinical course:  It was reported that the patient experienced the events of frequent evacuation, fatigue, frequent bowels/frequency reached up to 10 times day/mucus with the blood loss, weight loss, axial skeleton issue in lumbar/sacral region and vomiting and non-serious osteoporosis, feeling afraid to vomit, frequent bowels/frequency reached up to 10 times day/mucus with the blood loss, feeling anxious, low-grade fever and rectal pain with humira (adalimumab). information was also received from a healthcare professional. on unknown dates, the patient experienced axial skeleton issue in lumbar/sacral region, osteoporosis, frequent bowels/frequency reached up to 10 times day/mucus with the blood loss and rectal pain. in May2022, the patient experienced frequent bowels/frequency reached up to 10 times day/mucus with the blood loss, weight loss, feeling afraid to vomit and feeling anxious. on 03Jun2022, the patient experienced low grade fever. on 03Jun2022, the low grade fever resolved. on 04Jun2022, the patient experienced frequent evacuation, Fatigue and vomiting. In Jun2022, the feeling afraid to vomit and feeling anxious resolved. On unknown dates, axial skeleton issue in lumbar/sacral region and osteoporosis resolved. Imuran (azathioprine), methotrexate and medrol (methylprednisolone acetate) were also considered suspect. The primary reported said patient's bowel frequency reached up to 10 times day possibly to stretched out the supply of humira, because insurance in Puerto Rico only covers 50 percentage of the medication cost and the remaining cost was out of pocket. He lost 10 pounds over the course of seven months, then another 10 pounds in the week before he was admitted to a hospital on 01Jun2022. He had severe fatigue and he was hospitalized since 05Jun2022 and had received intravenous fluids as treatment for vomits. He had mucus with the blood. He was still in the hospital, but was down to three bowel movements daily and mild blood loss. He had a low grade fever at 17 hours one night of this hospital stay of 99 to 100 and received one dose of Tylenol. His body mass index was 16.5 as of 15Jun2022, but the height was unknown. He adjusts his diet to avoided rectal pain. He had skeletal issue occurred following the use of Imuran and caused osteoporosis, but once it was discontinued, a dual energy x-ray absorptiometry scan showed bones were back to normal, so the doctor suspected the patient was ingesting higher doses of Imuran than prescribed. The alternative etiology of frequent bowels, blood loss, weight loss, feeling afraid to vomit, feeling anxious and low-grade fever were possible lack of compliance or misadministration and for rectal pain was rice consumptions. It was unknown if patient was enrolled in a covid-19 vaccine trial. Primary reporter did not have the lot number information, because the packaging was discarded. The patient was treated with zoloft, flagyl, cipro and tylenol. The patient's past medications include: delzicol for unknown indication solu medrol for unknown indication causality for humira(adalimumab) the reporter's causality for the event(s) of frequent evacuation, fatigue, axial skeleton issue in lumbar/sacral region, vomiting, osteoporosis and frequent bowels/frequency reached up to 10 times day/mucus with the blood loss unknown onset was not provided. The reporter's causality for the event(s) of frequent bowels/frequency reached up to 10 times day/mucus with the blood loss onset in May2022, weight loss, frequent bowels/frequency reached up to 10 times day/mucus with the blood loss onset in May2022, feeling afraid to vomit, feeling anxious, low-grade fever and rectal pain with humira(adalimumab) was no reasonable possibility. Company's opinion is that there is no reasonable possibility that the events of frequent evacuation, fatigue, frequent bowels/frequency reached up to 10 times day/mucus with the blood loss onset in May2022, weight loss, axial skeleton issue in lumbar/sacral region, frequent bowels/frequency reached up to 10 times day/mucus with the blood loss onset in May2022, vomiting, osteoporosis, feeling afraid to vomit, frequent bowels/frequency reached up to 10 times day/mucus with the blood loss unknown onset, feeling anxious, low grade fever and rectal pain are related to humira (adalimumab).  The reporter's assessment of the causal relationship of "vomiting", "frequent bowels/frequency reached up to 10 times day/mucus with the blood loss", "frequent evacuation fatigue", "weight loss", "feeling afraid to vomit", "feeling anxious" and "low grade fever" with the suspect product(s) BNT162b2 was not provided at the time of this report. Since no determination has been received, the case is managed based on the company causality assessment.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.; Sender's Comments: Based on known drug safety profile, there is reasonable possibility of causal association between the events and BNT162B2.
