Abstract

We report a case of a 63-year-old HIV-positive Japanese male with a CD4 cell count of 127/μL who was admitted to our hospital because of suspected malignant lymphoma. Initial blood tests revealed anemia, thrombocytopenia, hypoalbuminemia, and hypergammaglobulinemia. Imaging tests revealed a lung nodule, bilateral pleural effusion, hepatosplenomegaly and generalized lymphadenopathy. No evidence of malignant lymphoma or multicentric Castleman's disease was noted on biopsy specimens; however, Kaposi sarcoma-associated herpesvirus (KSHV)-encoded latency-associated nuclear antigen-1-positive cells were observed as well as an elevated interleukin (IL)-6, IL-10 and KSHV viral load. He fulfilled the novel diagnostic criteria for KSHV-associated inflammatory cytokine syndrome (KICS). After initiating antiretroviral therapy, his symptoms and radiological abnormalities drastically improved. After 1-year follow-up, his HIV was well controlled without any relapsing symptoms.

HIV/AIDS infection increases the risk of non-communicable diseases common in the aged including HIV/AIDS-related malignancies. Discover the latest research in HIV/AIDS-related malignancies.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Castleman Disease

Castleman disease is a rare disorder that involves an overgrowth of cells in the lymph nodes. Unicentric Castleman disease affects one lymph node, usually in the chest or abdomen. Multicentric Castleman disease affects multiple lymph nodes, commonly located in the neck, collarbone, underarm and groin areas. Discover the latest research on Castleman disease here.
