A 2-year-old boy is sent for immunologic testing because of recurring respiratory infections, including several bouts of pneumonia. The results show decreased immunoglobulin levels, especially IgG. Although his white blood cell count was within the normal range, the lymphocyte count was low. Flow Cytometry (cellular separation based on size and CD markers) was performed to determine if a particular subset of lymphocytes was low or missing. It was determined that he had a low number of CD3+ lymphocytes, although the CD19+ lymphocyte population was normal. How can this be interpreted? In other words explain the roles of the cell populations described, how the decrease or normal level of each affects the function of the patient’s immune system. How does this support or relate specifically to the patients recurring bacterial infection?

Case 3: A 2 year old boy is sent for immunologic testing because of recurring respiratory infections including several bouts of pneumonia. The results show decreased immunoglobulin levels, especially of IgG. Although his WBC count was within the normal range, the lymph count was low. Flow cytometry was performed to determine the levels of different classes of lymphocytes. The results showed a decrease in CD4+ cells. The CD19+ lymph population was normal. (5) a.

Peter is an 18-month-old boy that was born after an uneventful pregnancy. He weighed 6 lbs 12 oz at birth and was 21.4 inches long. Soon after going home, he developed a persistent ear infection that was finally cleared after a 30-day course of antibiotics. At 2-months-old and again at 8-months-old, Peter was admitted to the pediatric intensive care because of aggressive Haemophilus influenzaepneumonia. When he was 12-months-old he developed a severe case of strep throat. In each case, the infections...

Case Study - Diseases of the Immune System. Peter was born after an uneventful pregnancy and weighed 3.1kg. At 3 months, he developed otitis media and an upper respiratory tract infection. At the ages of 5 months and 11 months, he was admitted to hospital with Hemophilus influenza pneumonia. The infections responded promptly to the appropriate antibiotics on each occasion. When 16 months old, he had a relapse of otitis media. He is the fourth child of unrelated parents: his...

John Fitzgerald was well for the first 10 months of his life. In the next year he had pneumonia once, several episodes of otitis media, and on one occasion developed erysipelas (streptococcal skin infection) on his right cheek. These infections were all treated successfully with antibiotics. John's mom was a nurse in Norwalk OH, and to her it seemed like John was always on antibiotics. John's mom worried about such things, as she had had two brothers, each of whom...

Susan and Joe were worried. Their little boy, Daniel, had been having an awful lot of bacterial infections and he was barely a year old. It seemed that the antibiotics cleared up one bacterial respiratory infection only to have another follow shortly. The scary thing was that Daniel had just fought off a case of pneumonia caused by Pneumocystis carnii, a fungal infection that was usually found in people with HIV. Waiting for the test results of an HIV test...
