AB Endothelin-1 is a recently identified cytokine with potent
vasoconstrictor activity which is associated with various diseases
involving blood vessels. HIV-1 related retinal microangiopathic syndrome
is a frequent finding in patients with AIDS or AIDS-related complex,
presenting predominantly with retinal cotton-wool spots. We investigated
55 HIV-1 infected patients by ophthalmoscopy and for endothelin-1
immunoreactivity in plasma and an additional 76 HIV-1 infected patients
only for endothelin-1 levels. For reference values 13 age-matched
healthy subjects were studied. In 18 of 55 patients (33%) investigated
ophthalmoscopically we found evidence of microangiopathic syndrome.
Overall, the mean endothelin-1 immunoreactivity in plasma of HIV-1
infected patients was significantly elevated as compared to controls
(4.28 +/- 3.62 versus 2.72 +/- 0.67 fmol/ml, P < 0.0001). HIV-1 infected
patients with retinal microangiopathic syndrome had significantly higher
plasma levels of endothelin-1 immunoreactivity (4.59 +/- 1.38 fmol/ml)
compared to HIV-1 infected patients without microangiopathic syndrome
(3.18 +/- 1.64 fmol/ml, P = 0.003). Correlation analysis revealed that
endothelin-1 immunoreactivity in plasma had no significant association
with disease progression, CD4 cell count, beta 2-microglobulin,
neopterin, or age. Endothelin-1 immunoreactivity in plasma was
correlated exclusively with retinal microangiopathic syndrome in one or
both eyes (r = 0.45, P = 0.0006) and with the number of cotton-wool
spots (r = 0.50, P = 0.0001). In conclusion, HIV-1 related retinal
microangiopathic syndrome is associated with elevated plasma levels of
endothelin-1. By virtue of its potent vasoconstrictor activity
endothelin-1 may be involved in the pathogenesis of HIV-1 related
vascular disease.
