PROBLEM: The effect of mini‐dose heparin/aspirin (H/A) alone vs. combined intravenous immunoglobulin G (IVIg) and H/A on in vitro fertilization (IVF) birthrates in women who test seropositive for antiphospholipid antibodies (APA+) was evaluated, as was the question of whether outcome is influenced by the gammaglobulin isotype(s) or the phospholipid (PL) epitope(s) to which the APAs are directed.

PROBLEMS: 1) Does the administration of heparin and aspirin (H/A) in combination with intravenous immunoglobulin G (IVIG) improve in vitro fertilization (IVF) implantation and birth rates in patients with recurrent IVF failures? 2) Is the effect of such treatment related to the antiphospholipid antibody (APA) status of the patients concerned?

PROBLEM: To compare the effect of heparin/aspirin therapy alone vs. heparin/aspirin in combination with intravenous immuno‐globulin (IVIg) immunotherapy on in vitro fertilization (IVF) outcome of patients who test positive for antithyroid antibodies (ATAs).

PROBLEM: Antiphospholipid antibodies (APAs) are important in the etiology of reproductive failure. Studies have shown that binding proteins are necessary for the detection of APAs. One of these, β2‐glycoprotein, has been shown to be necessary for detection of anticardiolipin antibodies. It is felt that some APAs may be directed to the binding protein itself, or to a combination of the binding protein and phospholipid.

Systemic Lupus Erythematosus (SLE) is a multisystem disease characterized by an increase in the secretion of autoantibodies. The mechanisms of autoantibody-induced disease have not been clarified. 1,25-Dihydroxy-vitamin D3 (1,25-D3) is known to be important in the regulation of normal human lymphocyte functions. Among its regulatory functions is the ability to inhibit mitogen-stimulated production of immunoglobulin. The experiments reported here explored the regulation of IgG production by peripheral blood mononuclear cells (PBMCs) of patients with inactive and active SLE. 1,25-Dihydroxyvitamin D3 inhibited mitogen-stimulated IgG production in cells from normal individuals and inactive SLE patients, but not spontaneous IgG production by PBMCs from active SLE patients. Addition of exogenous IL-2 (5-50 U/ml) to 1,25-D3-treated cells from all patient groups did not affect IgG production significantly under any conditions tested. The addition of IL-2 to PMBCs had no effect on IgG production in normal individuals or inactive SLE patients, but stimulated IgG production in PBMCs of active SLE patients. We conclude that the regulation of mitogen-stimulated IgG production in inactive SLE patients by 1,25-D3 and IL-2 is similar to normal individuals, but IgG production by active SLE PBMCs is unresponsive to 1,25-D3 regulation and is increased with the addition of IL-2.

PROBLEM: There is substantial data that support the efficacy of paternal leukocyte immunization (PLI) for the treatment of alloimmune mediated miscarriage; however, there is confusion regarding the laboratory test that should be performed to determine levels of maternal anti‐paternal leukocyte antibodies (MAPLA).
