BACKGROUND: We recently identified a regulatory rheumatoid factor (regRF), the production of which is associated with autoimmune disease resistance and remission. In studies of regRF in the blood of healthy rats, spontaneous increases in the regRF level were noted. We suggest that in the normal state, a mechanism exists for maintaining the activity of the pool of regRF-producing lymphocytes at a level that makes it possible to control the expansion of autoreactive lymphocytes. OBJECTIVE: The purpose of this study was to test the hypothesis that the endogenous stimulator of regRF production is Fc fragments of IgG that are formed upon exposure to the proteases of neutrophils...

Kikuchi-Fujmoto disease (KFD), also known as "histiocytic necrotizing lymphadenitis", is a rare lymphadenitis of unknown origin, but with an excellent prognosis. It is more common in Asia, but isolated cases are also reported in America, Africa and Europe. The disease can have an acute or subacute course, usually develops in 1 to 3 weeks, with spontaneous resolution in 1-4 months. The main clinical sign is cervical lymphadenopathy, especially in the posterior cervical triangle with bulky and painful lymph nodes, usually affecting only one side; rare cases of generalized lymphadenopathy can be seen...

Leukocytosis is among the most common findings on peripheral blood smear. A wide range of causes may mediate this finding, and careful clinical and laboratory evaluation assist in differentiating between benign and malignant causes of increased white blood cell counts. In this article, various nonmalignant causes are explored, including infectious, inflammatory, autoimmune, and allergic. In addition, malignant causes of leukocytosis are discussed, including myeloproliferative disorders, acute leukemia, and chronic leukemia, as well as treatment and monitoring for patients with these diseases...

Bispecific antibodies are a rapidly growing class of therapeutic molecules, originally developed for the treatment of cancer but recently explored for the treatment of autoimmune and infectious diseases. Bordetella pertussis is a reemerging pathogen, and several of the key symptoms of infection are caused by the pertussis toxin (PTx). Two humanized antibodies, hu1B7 and hu11E6, bind distinct epitopes on PTx and, when coadministered, mitigate disease severity in murine and baboon models of infection. Here we describe the generation of a bispecific human IgG1 molecule combining the hu1B7 and hu11E6 binding sites via a knobs-in-holes design...

Skin lesions are frequently encountered in clinical practice which can be a presentation of systemic diseases not excluding an occult malignancy. Commonly reported paraneoplastic dermatologic manifestations include acanthosis nigricans, dermatomyositis, erythroderma, hypertrophic osteoarthropathy, Sweet syndrome, and paraneoplastic pemphigus (PNP). PNP is a rare autoimmune mucocutaneous disease characterized by severe stomatitis, polymorphic skin eruptions, and associated underlying neoplasms most commonly non-Hodgkin's lymphoma, chronic lymphocytic leukemia, and Castleman disease...

We report a patient with a clinical picture of suggestive for adult-onset Still's Disease (ASOD) due to Bartonella infection. A 42-year-old immunocompetent man was admitted with fever, rash, arthralgia and sore throat. As his clinical picture suggested ASOD except unusual skin manifestation, we treated him on steroid and ibuprofen. His fever and constitutional symptoms responded immediately within 24hrs of commencing therapy, yet rash and leukocytosis remained. Meanwhile, Bartonella infection was proved by culture of bone marrow...

Systemic lupus erythematosus (SLE) is an autoimmune disease and can cause multi-organ damage. Peritoneal involvement, also called lupus peritonitis, is a rare but sometimes fatal manifestation. Deposition of immune complexes consisting of immunoglobulin G and complement is considered to be involved in the pathogenesis of lupus peritonitis; however, it remains unknown whether inflammatory cytokines contribute to the pathology of this manifestation. Here we present two patients with treatment-resistant lupus peritonitis: a 37-year-old woman with a 26-year history of SLE who had been treated with prednisolone and cyclophosphamide followed by azathioprine and a 65-year-old woman with a 33-year history of SLE who had been treated with prednisolone alone...

Ras-associated autoimmune leukoproliferative disorder (RALD) is a chronic, nonmalignant condition that presents with persistent monocytosis and is often associated with leukocytosis, lymphoproliferation, and autoimmune phenomena. RALD has clinical and laboratory features that overlap with those of juvenile myelomonocytic leukemia (JMML) and chronic myelomonocytic leukemia (CMML), including identical somatic mutations in KRAS or NRAS genes noted in peripheral blood mononuclear cells. Long-term follow-up of these patients suggests that RALD has an indolent clinical course whereas JMML is fatal if left untreated...

The erythrocyte sedimentation rate (ESR) has been used as an index for inflammatory conditions, such as infectious diseases, autoimmune diseases, and malignancies. The ESR values of a 37-year-old male with marked leukocytosis due to chronic myeloid leukemia showed remarkable differences between two devices of the same model (Ves-Matic 30, DIESSE Diagnostica Senese). From the appearance of the tested tube after the ESR measurement, the values obtained using one device might have been falsely low, whereas the values obtained using the other device were likely to have been accurate...
