IgA nephropathy associated with thalassemia: A case report

Abstract

Background: Thalassemia is a group of hereditary diseases characterized by a common recessive monogenic hematological disorder, presenting a significant public health concern in the developing countries. Recent studies have identified the renal effects of thalassemia syndrome. Chronic hypoxia, long-term anemia, iron overload, and iron chelators are the major causes of renal tubular dysfunction and glomerular filtration abnormalities, while glomerulonephritis is not considered a major cause of abnormal urinalysis. Case presentation: We report a case of a 38-year-old female patient with immunoglobulin A (IgA) nephropathy accompanied by anemia who was misdiagnosed initially, but was diagnosed with alpha-thalassemia after gene tests. We administered a combination of oral prednisolone, leflunomide, and angiotensin receptor blockers as well as folic acid and mecobalamin. During the follow-up, her proteinuria was significantly reduced, and her anemia was improved. Conclusions: The possibility of occurrence of thalassemia should be considered in IgA nephropathy complicated with refractory anemia, especially in high-incidence areas of the disease.
