A premature neonate was admitted to the neonatal intensive care unit. The blood bank performed a neonatal antibody profile consisting of blood type, antibody screen, and a direct antiglobulin test. The neonate phenotypes as group A, D-positive.the antibody screen is negative. The doctor placed a transfusion  order for 20 mL of RBCs. 1. Can this neonate receive type-specific RBC products? 2. If the baby had a passive maternal ABO antibody, what blood group would be compatible with the neonate?

What would happen if someone did not receive a compatible blood type during a blood transfusion? (Hint: Reaction between antigens and antibodies when blood typing.)

A 2-and-a-half-year-old kid who weighed 11kg and had no previous/ known medical conditions was hospitalised for various bruises for one week owing to thrombocytopenia. Immune thrombocytopenic purpura was identified as the cause.    In light of bleeding manifestations and extremely severe thrombocytopenia with platelet level of 3 109/L, patient was suggested for two units of whole blood, derived platelet transfusion and began on intravenous immunoglobulin at a dose of 1 mg/kg. Due to the lack of blood group B platelets, the patient, who is B Rhesus D positive, got O RhD positive WB-derived platelets.    During the second unit of platelet transfusion, the kid started to experience, shortness of breath, chill, and rigor. the patient became worse with a fever of 38 C, an oxygen saturation of 80% in room air, hypotension (94/56 mmHg), tachycardia (156 beats/minute), and tachypnea (26 breaths/minute).    Blood film evidence of spherocytosis and tiny agglutinations helped to explain why the…

A 45-year-old man with HIV infection comes to the office because of a 6-week history of swelling near the left side of his neck. His most recent CD4+ T-lymphocyte count was 42/mm3 (N>500), and plasma HIV viral load was 55,000 copies/mL. He currently takes no medications. His temperature is 38oC (100oF), pulse is 72/min, respirations are 12/min and blood pressure is 120/81 mmHg. Physical examination shows a left supraclavicular mass. Immunohistochemical staining of a biopsy specimen of the mass confirms the presence of the causal virus’s DNA and replication within lymphoma cells but not in nearby normal cells. Which of the following is the most likely explanation for the tumor formation? a) Chronic immune activation of B lymphocytes b) Chronic immune activation of T lymphocytes c) Inhibition of B-lymphocyte tumor surveillance d) Inhibition of T-lymphocyte tumor surveillance e) Malignant transformation of B lymphocytes f) Malignant transformation of T lymphocytes
