Objectives: Multiple sclerosis (MS) is a chronic inflammatory disease of the human central nervous system. In the present study, we aimed to determine adiponectin, tumor necrosis factor-α, interleukin (IL)-12p70, and IL-13 levels in the sera of patients with MS and to investigate the effects of interferon (IFN), glatiramer acetate (GA), and immunosuppressive treatment regimens on these parameters. Methods: Fifty-seven patients with MS and 34 healthy controls were enrolled into the study. Serum cytokine levels were measured using enzyme immunoassay. Results: Significantly elevated levels of IL-12p70 and IL-13 were found in the sera of patients with MS, but decreased adiponectin levels were found in patients’ sera compared to healthy controls. The levels of IL-12p70 and IL-13 in the IFN therapy group were higher than those of the healthy controls. However, the IL-12p70 and IL-13 levels in the GA therapy group were not different from those of the healthy controls. There were no differences with regard to adiponectin levels among the subgroups of patients with MS according to therapy regimen and the healthy controls. At the end of a 2-year follow-up period, Expanded Disability Status Scale (EDSS) values were found to be increased in the IFN therapy group but unchanged in the GA therapy group. Conclusions: These findings suggest that adiponectin, IL-12p70, and IL-13 may play a role in the pathogenesis of MS. Additionally, GA therapy regimens in MS are more effective than IFN therapy with respect to decreasing the levels of IL-12p70 and IL-13 and stabilizing the EDSS value.

Vitamin D deficiency is suggested to be associated with Parkinson's disease (PD). Our aim was to investigate the serum 25-hydroxyvitamin D (25OHD) levels of PD patients in Turkish cohort, to investigate any association of vitamin D binding protein (GC) genotypes with PD due to the significant role of GC in vitamin D transport, to determine whether vitamin D receptor (VDR) haplotype that we previously demonstrated to be a risk haplotype for AD is also a common haplotype for PD and to investigate any relevant consequence of serum 25OHD levels, GC or VDR genotypes on clinical features of PD. Three hundred eighty-two PD patients and 242 healthy subjects were included in this study. The serum 25OHD levels were investigated by CLIA, and GC and VDR SNPs were evaluated with LightSnip. Our results indicated a strong relationship between low serum 25OHD levels and PD (p < 0.001). rs7041 of GC and ApaI of VDR were associated with the PD risk (p < 0.05). Minor allele carriers for BsmI of VDR gene in both PD patients and healthy subjects had significantly higher levels of serum 25OHD (p < 0.05). The homozygous major allele carriers for rs2282679, rs3755967 and rs2298850 of GC gene in PD patients with slower progression had significantly higher levels of serum 25OHD (p < 0.05). Minor allele carriers for FokI of VDR gene were more frequent in patients with advanced-stage PD (p < 0.05). Consequently, this is the first study demonstrating GC gene as a risk factor for PD. The relationship between PD's clinical features and low 25OHD or risk genotypes might have effects on PD independently.

Ophthalmoplegic migraine has been considered to have a microvascular, ischemic etiology, but more recently it has been reclassified as a demyelinating condition affecting the oculomotor. To our knowledge, this is the first ophthalmoplegic migraine case presented pretreatment and post-treatment with clinical photographic documentation and an MRI showing enduring thickening of the oculomotor nerve although symptoms and contrast enhancement resolved.
