To determine the changes in the subfoveal choroidal thickness (CT), the foveal thickness (FT), and the serum level of vascular endothelial growth factor (VEGF) after thalidomide treatment in patients with the polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome.
This was retrospective, observational case series. We studied 22 eyes of 11 treatment-naïve patients with the POEMS syndrome at the Chiba University Hospital from January 2013 through May 2015. The subfoveal CT and FT were determined by enhanced depth imaging optical coherence tomography (EDI-OCT) at the baseline and at 6 months after the thalidomide treatment. The serum level of VEGF was also determined by enzyme-linked immunosorbent assays (ELISAs) at the baseline and at 6 months after the thalidomide treatment. The correlations between the serum level of VEGF and the subfoveal CT or the FT at the baseline and at 6 months after thalidomide treatment were determined.
At the baseline, the mean subfoveal CT was 455.7 ± 56.0 µm (right eye, 457.8 ± 53.2 µm; left eye, 453.7 ± 61.3 µm), the mean FT was 245.9 ± 50.9 µm (right eye, 255.7 ± 64.0 µm; left eye, 236.1 ± 33.6 µm), and the mean serum level of VEGF was 8103 ± 3617 pg/ml. At 6 months after thalidomide treatment, the mean serum level of VEGF significantly decreased to 1556 ± 1751 pg/ml (P<0.001) and the subfoveal CT significantly decreased along with an improvement in the serum level of VEGF to 315.3 ± 82.2 µm (right eye, 319.2 ± 86.9 µm, P<0.0001; left eye, 311.3 ± 81.2 µm, P<0.0001). On the other hand, the mean FT did not significantly change from the baseline (both eyes, 227.5 ± 34.4µm, P>0.05; right eye, 227.4 ± 34.2 µm, P>0.05; left eye, 227.6 ± 36.2 µm, P>0.05). At 6 months after treatment, the change in subfoveal CT from baseline in all eyes was significantly and linearly related to the change in the serum levels of VEGF from baseline (r=0.66, P<0.001) but the change in FT from baseline in all eyes was not significantly related to the change in the serum levels of VEGF.
The decrease in the subfoveal CT along with the decrease in the serum level of VEGF suggests that serum levels of VEGF might influence the choroidal thickness in patients with POEMS syndrome.
