Increased soluble CD72 in systemic lupus erythematosus is in association with disease activity and lupus nephritis.

Introduction: B cell receptor (BCR) -mediated signals are enhanced when CD72 expression is deficient on B cells in autoimmune diseases. The significance of soluble CD72 (sCD72) has not been elucidated.

Methods: Soluble CD72 was analyzed in the serum of 159 SLE patients, 40 rheumatoid arthritis (RA) patients, and 100 healthy individuals.

Characteristics and Outcome of Patients Diagnosed With HIV at Older Age.

To characterize the clinical, virological, and immunological status at presentation as well as the outcome of patients diagnosed with HIV above the age of 50. A retrospective study of 418 patients newly diagnosed with HIV in 1 Israeli center, between the years 2004 and 2013. Patients with new HIV diagnosis ≥ 50 years of age defined as "older' and < 50 defined as "younger.

Angiotensin-converting enzyme inhibitor-induced angioedema.

Angiotensin-converting enzyme inhibitors (ACE-I) are widely used, effective, and well-tolerated antihypertensive agents. The mechanisms by which those agents act can cause side effects such as decreased blood pressure, hyperkalemia, and impaired renal function. ACE-I can induce cough in 5%-35% and angioedema in up to 0.

Type I interferon signature in systemic lupus erythematosus.

Type I interferons (IFN) are primarily regarded as an inhibitor of viral replication. However, type I IFN, mainly IFNalpha, plays a major role in activation of both the innate and adaptive immune systems. Systemic lupus erythematosus (SLE) is a chronic, multi-systemic, inflammatory autoimmune disease with undefined etiology.

Novel biological treatments for systemic lupus erythematosus: current and future modalities.

Current treatments for systemic lupus erythematosus (SLE) are effective in reducing morbidity and mortality but are not specific and have severe adverse effects. Based on understanding of the different dysregulated immunological pathways involved in SLE pathogenesis, specific targeted therapies were developed. This review presents the current and the near-future novel biological immune targeted treatments, such as B cell-targeted therapy, cytokine blockade, peptide-based treatments and other novel treatments for SLE.

High alpha-defensin levels in patients with systemic lupus erythematosus.

Innate immunity plays a role in systemic lupus erythematosus (SLE). Our objective was to determine the levels of defensins, which are antimicrobial and immunomodulatory polypeptides, in SLE. Sera from SLE patients and healthy controls were tested for pro-inflammatory human beta-defensin 2 (hBD-2) and for alpha-defensin human neutrophil peptide 1 (HNP-1).
