The Association between Multiple Myeloma and Ankylosing Spondylitis: A Report of Two Cases / 대한혈액학회지

Multiple myeloma is a malignant disease of plasma cells, whereas ankylosing spondylitis is a chronic inflammatory disease of axial joints. The relationship between the two diseases is uncertain, but chronic inflammation could trigger multiple myeloma. The authors report the cases of two ankylosing spondylitis patients with a disease duration of more than 20 years, that subsequently developed IgA kappa and IgG lambda chain myeloma, respectively, and discuss the possible pathogenetic relationship between these diseases.

Progressive Multifocal Leukoencephalopathy in a Patient with Systemic Lupus Erythematosus / 대한류마티스학회지

Progressive multifocal leukoencephalopathy (PML) is a rare, serious, and usually fatal demyelinating disease that occurs predominantly in severely immunosuppressed patients. The disease is caused by the infection of oligodendrocytes with JC virus that is widely distributed as a latent infection in the general populations. PML has been described mainly in patients infected with the human immunodeficiency virus. However, other immune-suppressed patients including malignancies and organ transplants can be affected with JC virus infection. Recently it is suggested that rheumatologic diseases, including systemic lupus erythematosus (SLE), rheumatoid arthritis, dermatomyositis, polymyositis, wegener`s granulomatosis be known to be at risk of developing PML. We report a case of PML in a patient with SLE.

A Case of Endogenous Endophthalmitis and Multifocal Pneumonia Complicated by Renal Abscess and Sepsis due to Escherichia coli / 대한신장학회지

Metastatic or septic endogenous endophthalmitis is a rare, but devastating complication of systemic septicemia. This condition may become more common as the number of chronically debilitated patients and the use of invasive procedures increase. Many etiologic organisms (gram-positive, gram-negative and fungi) and many clinical conditions (pyelonephritis, endocarditis, meningitis, pneumonia) have been reported to cause endogenous endophthalmitis. Risk factors include most of the known reasons for immune suppression and chronic illness. A high clinical suspicion is required in early diagnosis and treatment. Early antibiotics and vitrectomy are more widely accepted as therapeutic modalities.
