Glycyrrhizin (GL) not only has an inhibitory effect on HIV replication but also exhibits interferon-inducing and natural killer (NK)-enhancing effects and improves liver dysfunction. Thus, large doses of GL (200-800 mg/day) were intravenously administered for more than 8 weeks to 9 hemophilia A patients with HIV infection (asymptomatic carrier, AC). Lymphocyte count increased in all 9 cases. OKT4 OKT8 ratio was elevated in 6 out of the 9 cases and OKT4-positive lymphocytes increased in 8 out of the 9 cases; 66.7% and 88.9% improvement, respectively. Changes in NK cell activity and mitogenic responsiveness to PHA, Con A and PWM were not significant. Liver dysfunction, noted in 4 cases, clearly improved. Serum electrolytes, protein, lipids, and renal function were within normal levels and no serious side-effects were observed during treatment. On the other hand, in 3 cases of hemophilia without HIV infection, the number of OKT4 lymphocytes was not significantly altered during treatment. From these results, large dose administration of GL to HIV-positive hemophilia patients (AC) seems to be effective in preventing development of AC into AIDS by raising the number of decreased OKT4 lymphocytes and improving liver dysfunction.

The distribution of T-lymphocyte subsets was assessed using monoclonal antibodies in 20 symptom-free patients with haemophilia. In 15 patients, the T-cell subsets appear substantially balanced with only a moderate reduction in the proportion and absolute number of OKT4 positive cells. In the remaining 5, all with a reversed OKT4/OKT8 ratio, the proportion and absolute number of OKT4 positive cells was significantly reduced (p less than 0.0002) while the absolute number of OKT8 positive cells was normal or reduced although the proportion of these cells appeared increased. Functional studies, testing the proliferative response to PHA and PWM, were normal in all cases including those with immunological abnormalities. These results suggest that a proportion of patients with classic haemophilia show some immunological abnormalities similar to those observed in patients with acquired immunodeficiency syndrome and that regular evaluation of several immunological parameters is warranted in these patients.

Previous studies interpreted increases of soluble Fas (sFas) in the plasma during disease progression in HIV-infected patients as evidence of increased apoptosis of CD4(+) lymphocytes. We studied whether sFas and sFas ligand (sFasL) plasma levels are associated with CD4(+) and CD8(+) lymphocyte counts, plasma viral load, and IgM, IgG, C3d, and gp120 complexes on circulating CD4(+) blood lymphocytes in long-term surviving HIV-infected hemophilia patients, most of whom were receiving HAART. Twenty-six hemophilia patients who were infected with HIV in the early 1980s were investigated in 1997, 1998, and 1999. HAART was initiated in 1996 and 1997 in most patients. Lymphocyte subpopulations and immune complex-coated CD4(+) lymphocytes in the blood were investigated by flow cytometry, plasma viral load (HIV-1 mRNA copies/ml plasma) was tested with HIV-1 QT Nuclisens kits, sFas (ng/ml) and sFasL (ng/ml) plasma levels were measured with MBL ELISA kits, and the in vitro response of patient lymphocytes was tested in cell cultures. During the period from 1997 to 1999 we observed an increase in sFas plasma levels (p = 0.003) as well as in CD4(+) (p = 0.004) and CD8(+) (p = 0.023) cell counts; a decrease in IgG (p = 0.047), C3d (p = 0.024), and gp120 (p = 0.001)-coated CD4(+) lymphocytes in the blood; and a decrease in the number of impaired mitogen stimulation assays (p = 0.013). sFas was negatively associated with viral burden (r = -0.662, p = 0.0002) as well as with CD4(+)IgM(+) (r = -0.554, p = 0.004), CD4(+)IgG(+) (r = -0.431, p = 0.031), CD4(+)C3d(+) (r = -0.551, p = 0.041), and CD4(+)gp120(+) (r = -0.430, p = 0.041) blood lymphocytes, CD8(+)DR(+) cell counts (r = -0.700, p = 0.016), and impaired in vitro responses of patient lymphocytes to PHA (r = -0.475, p = 0.016). sFasL was negatively associated with total lymphocyte counts (r = -0.433, p = 0.027), as well as with absolute numbers of CD3(+) (r = -0.492, p = 0.011) and CD8(+) (r = -0.432, p = 0.027) cells. We conclude that, contrary to expectations, sFas plasma levels increased in long-term surviving HIV-infected hemophilia patients receiving HAART, concomitant with increases in CD4(+) and CD8(+) cell counts. Increased sFas may reflect the growing pool of T lymphocytes that recovers because of a decreasing viral burden and a decreasing immune complex load of CD4(+) lymphocytes.
