Abstract:
Few cases of IgA nephropathy with angioimmunoblastic T-cell lymphoma (AITL) have been reported. We herein present the case of a 79-year-old Japanese man with AITL and IgA nephropathy. The patient presented with generalized edema, fatigue, and fever. Laboratory investigations revealed polyclonal gammopathy with a high level of IgA, microscopic hematuria, proteinuria, and some other immunological abnormalities. Computed tomography revealed generalized lymphadenopathy. A diagnosis of AITL and IgA nephropathy was made based on inguinal lymph node and renal biopsies. Following chemotherapy for AITL, the patient's edema, microscopic hematuria, and proteinuria were alleviated. These findings indicate that IgA nephropathy may occur in AITL patients.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
