Unlike primary central nervous system lymphomas (PCNSLs) in patients with AIDS or organ transplants, PCNSLs in the elderly are usually not considered to be mediated by Epstein Barr virus (EBV); hence, diagnostic studies for EBV are not routinely performed. We encountered 4 patients, 65 years or older, who developed EBV-associated PCNSLs and who had been treated with a variety of immunosuppressi...

the immunosuppressive effect of antimacrophage serum (ams) on the primary immune response of mice to sheep red blood cells (srbc) was studied. ams, given before a small dose of antigen, abrogated the immune response. transplantation of normal, galss-adherent macrophages enabled ams-treated animals to respond to srbc, while administration of lymph node lymphocytes did not reveres ams - induced i...

Renal transplantation is the preferred treatment modality for patients with ESRD who are good surgical risks and able to comply with chronic immunosuppressive medications. Clinical transplantation has advanced significantly, with most transplant centers reporting 1-yr renal allograft survival rates of better than 80%. Nevertheless, rejection and a progressive loss of allografts over time contin...

BACKGROUND Biologic therapies are widely used in inflammatory diseases, and they are associated to an increased infection risk, especially to granulomatous and intracellular infections such as Legionella. RESULTS A review of the literature revealed 105 cases of Legionella pneumonia in patients taking biologic therapies. Sixty-four patients (65.3%) were treated with infliximab, 23 (23.5%) with...

The cornea is the most commonly transplanted tissue in the body. Although corneal grafts generally have high success rates, transplantation onto inflamed and vascularized host beds, or so-called high-risk corneal transplantation, has a high rate of graft rejection. The management of this high-risk corneal transplantation is challenging and involves numerous measures. One of the key measures to ...

Immunosuppressive therapy can improve clinical, biochemical and histological features and considerably prolong survival in patients with autoimmune hepatitis. Although ethnicity may affect disease severity and presentation, the long-term outcome of immunosuppression in Korean populations is unknown. This study was aimed to assess the efficacy of immunosuppressive therapy and determine the progn...

INTRODUCTION Worldwide, there are approximately 8 million new cases and 3 million deaths from tuberculosis (TB) each year. TB affects the entire body and the eye. Although ocular TB is considered rare, its incidence has varied widely across time, patient populations, and geography. We report 2 patients with unique presentations of ocular TB and detail the treatment and outcome of the disease. ...

The immune function test is an integrated measure of total mitogen-inducible CD4(+) T cell metabolic activity in the peripheral blood, and it is used to guide the dosing of immunosuppressive medications after solid organ transplantation. Recently, low CD4(+) T cell metabolic activity due to pharmacologic immunosuppression has been linked to rapidly progressive cirrhosis in hepatitis C virus (HC...

BACKGROUND Pyoderma gangrenosum (PG) is a rare skin disorder of the neutrophilic dermatoses spectrum that can mimic wound infections in surgical patients. PG after breast surgery has been reported but in limited amounts in autologous breast reconstruction patients. We present the first case of PG after a delayed bilateral deep inferior epigastric perforator flap breast reconstruction in the set...
