Home-based subcutaneous immunoglobulin after switch from intravenous immunoglobulin improved quality of life in pediatric patient with common variable immunodeficiency A case report

Common variable immunodeficiency (CVID) is one of the primary immunodeficiency. Regular immunoglobulin G (IgG) replacement therapy is often performed for patients with CVID. We experienced a patient who was hospitalized in our hospital for repeated pneumonia and diagnosed CVID at the age of 10 years. He had often been absent from school due to infectious diseases. We were administered intravenous IgG (IVIG) two times and his serum level of IgG became over 1,000 mg/dL. Afterward, he was affected the hand-foot-and-mouth disease one week after discharge. At that time, his IgG level decreased to 751 mg/dL. To maintain stable IgG trough levels, we introduced subcutaneous IgG (SCIG). Since then, his IgG levels remained around 1,000 mg/dL, he has lived without suffering from infectious diseases. There are some reports that IVIG and SCIG were compared and SCIG was able to obtain a stable IgG trough levels to prevent infection. In addition, because our patient is a mother and child family, it was difficult to visit the outpatient department frequently, so it was desirable to infuse at home. We experienced a patient who had a stable trough levels with SCIG and improved quality of life, so we report this case with literature reviews.
