Antiphospholipid antibodies in relation to sterility/infertility.

Of the systemic autoimmune diseases that lead to sterility/infertility, antiphospholipid syndrome (APS) has an outstanding importance; it may be associated with abortion and premature birth which are included in its diagnostic criteria, as well as preeclampsia, pregnancy-induced hypertension, foetal retardation, miscarriage, stillbirth and sterility. Between 2004 and 2009, on the Department of Immunology in the Zala County Hospital, 100 female patients with sterility (st)/infertility (if) (33/67), (mean age: 34.08 years) underwent, in addition to history taking and physical examination, an assessment by immune-serologic tests (ANA, anti-dsDNA, ENA-Profile, anti-TPO, a-sperm, aCL, aPS, aβ2GP1, aANX, and aPT).

Combined plasmapheresis and high-dose intravenous immunoglobulin treatment in systemic sclerosis for 12 months: follow-up of immunopathological and clinical effects.

Systemic sclerosis (SSc) is an autoimmune disease which involves the skin, as well as several internal organs. Most therapies available in this disease are symptomatic. Authors present a case of diffuse SSc with progressive disease not responding to currently available treatments.

Intracytoplasmic cytokine expression and T cell subset distribution in the peripheral blood of patients with ankylosing spondylitis.

Objective: To determine the role of inflammatory mediators in the pathogenesis of ankylosing spondylitis (AS), we investigated peripheral blood lymphocyte subsets and their intracellular cytokine production.

Methods: The percentages of T and B lymphocytes, natural killer (NK) cells, activated T lymphocytes, CD4+ T helper (Th), and CD8+ T cytotoxic (Tc) cells were determined by flow cytometry in 42 patients with AS compared to 52 healthy controls. In order to assess circulating Th1/Th2 and Tc1/Tc2 subsets, we used a whole-blood cytometric assay based on the intracellular interferon-gamma, interleukin 4 (IL-4), and IL-10 expression of the cells.

Progressive divergent shifts in natural and induced T-regulatory cells signify the transition from undifferentiated to definitive connective tissue disease.

The objectives of the study is to determine clinical signs and distribution of peripheral T-cell subsets, B cells and T regulatory cells in patients with undifferentiated connective tissue disease (UCTD) and during the development toward well-established connective tissue diseases (CTD). The methods include 46 patients with UCTD were followed and investigated for differentiation into defined CTDs for 2 years. Cell subsets were determined on the basis of cell surface markers, intracellular cytokine production by flow cytometry and serum cytokine levels by ELISA.
