Prophylactic treatment can modify vascular risk biomarkers in high-frequency episodic and chronic migraine patients: a pilot study.

To evaluate whether preventive treatment can modify endothelial and oxidative biomarkers of vascular disease risk in patients with high-frequency episodic and chronic migraine. In this observational, prospective pilot study, 88 prophylactic treatment-naïve patients with episodic and chronic migraine and 56 healthy sex/age matched controls underwent ultrasonography exams and blood tests at baseline, and again in the migraine patients after 3 months' treatment with metoprolol or topiramate. Biomarkers for endothelial function and oxidative stress were analyzed. At baseline, patients with migraine in the low-frequency episodic group had differences exclusively in nitrates 17.6 versus 27.33 µM; p = 0.046 compared to the controls. However, when comparing the group comprised of patients with high-frequency episodic migraine and chronic migraine versus controls, statistically significant differences appeared in hsCRP 2.68 versus 1.64 mg/dL; p = 0.049, vWF antigen (133% vs. 110%; p = 0.020, vWF activity (111% vs. 90%; p = 0.010) and isoprostane levels (181 vs. 238 µM; p = 0.05). Only in the chronic migraine subgroup did we found statistically significant differences in CIMT (0.60 vs. 0.54 mm; p = 0.042) which were significantly greater than in the controls. After treatment, patients who respond to preventive treatment exhibited significantly higher levels of nitrates (24.2-13.8 µM; p = 0.022) and nitrites (10.4-3.43 µM; p = 0.002) compared than non-responders. Moreover, biomarker levels improved in treatment-responsive patients with migraine; hsCRP levels decreased from 2.54 to 1.69 mg/dL (p < 0.05), vWF activity levels decreased from 124 to 103 IU/dL (p = 0.003) and prothrombin activity decreased from 1.01 to 0.93 (p = 0.01). These differences were also observed in the high-frequency and chronic migraine subgroup and reach statistical significance in the case of hsCRP, which decreased from 2.12 to 0.83 mg/dL (p = 0.048). Patients with migraines have differences in biomarker levels compared to controls, suggesting endothelial and oxidative dysfunction. The greatest differences in biomarker levels compared to controls are observed in migraine patients in the high-frequency and chronic migraine subgroups. Based on our results, preventive treatment is capable of modifying markers of endothelial dysfunction and oxidative stress in migraine patients, even in cases of chronic and high-frequency migraine.

Diabetic Retinopathy and Skin Tissue Advanced Glycation End Products Are Biomarkers of Cardiovascular Events in Type 2 Diabetic Patients.

Risk of cardiovascular events is not homogeneous in subjects with type 2 diabetes; therefore, its early identification remains a challenge to be met. The aim of this study is to evaluate whether the presence of diabetic retinopathy and accumulation of advanced glycation end-products in subcutaneous tissue can help identify patients at high risk of cardiovascular events. For this purpose, we conducted a prospective study (mean follow-up: 4.35 years) comprising 200 subjects with type 2 diabetes with no history of clinical cardiovascular disease and 60 non-diabetic controls matched by age and sex. The primary outcome was defined as the composite of myocardial infarction, coronary revascularization, stroke, lower limb amputation or cardiovascular death. The Cox proportional hazard multiple regression analysis was used to determine the independent predictors of cardiovascular events. The patients with type 2 diabetes had significantly more cardiovascular events than the non-diabetic subjects. Apart from the classic factors such as age, sex and coronary artery calcium score, we observed that the diabetic retinopathy and advanced glycation end-products in subcutaneous tissue were independent predictors of cardiovascular events. We conclude that the diabetic retinopathy and advanced glycation end-products in subcutaneous tissue could be useful biomarkers for selecting type 2 diabetic patients in whom the screening for cardiovascular disease should be prioritized, thereby creating more personalized and cost-effective medicine.

A study to evaluate the effect of ultrasound treatment on nodules in multiple sclerosis patients.

Purpose/aim: Ultrasound has demonstrated anti-inflammatory and pain-relief benefits in several conditions such as cellulite or trauma events. We assessed the efficacy of ultrasound therapy on nodules associated with first-line treatments in multiple sclerosis patients. MATERIALS AND METHODS: Twenty-two multiple sclerosis patients were enrolled during 2013 and randomized to two groups: in the control group patients were treated only with a conventional gel prescribed for cellulite and nodules, while in the experimental group the gel was combined with ultrasound therapy. Patients were treated during 10 weeks and followed up for 10 additional weeks. Three nodules were assessed for each patient, measuring size, pain and redness at 0, 10 and 20 weeks. RESULTS: We found a significant decrease in both groups in size, pain and redness across the three visits (p < 0.0001 for size, p = 0.01 and p < 0.0001 for pain, and p = 0.0002 and p < 0.0001 for redness, respectively for the difference at visit 2 and 3 with respect to visit 1). More interestingly, we observed a greater reduction in pain and redness in the ultrasound-treated group, but the difference was only statistically significant at 10 weeks (p = 0.01 for both pain and redness). On the third visit, no differences between control and experimental groups were detected, both achieving the same levels in measured variables. CONCLUSIONS: Both treatments are useful to improve skin reaction after first-line treatments, but ultrasound in combination with gel achieves a faster reduction in pain and redness, suggesting that ultrasound treatment might be a good analgesic for nodule management in multiple sclerosis patients.

Patients with recently-diagnosed adult celiac disease were evaluated with the Gastrointestinal Symptom rating Scale (GSRS) and Psychological General Well-Being Index (PGWBI) to evaluate their psychological alterations, the association between any alterations and gastrointestinal symptoms, and their outcome after starting a gluten-free diet. The patients underwent nutritional assessment and then started a gluten-free diet; they were reassessed 6 months later. Quantitative variables are expressed as the median and 25th-75th percentiles. Results: We included 21 patients, 17 women and 4 mena, with a mean age of 43 years (31-47). The results of histological analysis were compatible with Marsh I lesions in 6 patients, Marsh IIIa in 6 and Marsh IIIb in 9. At baseline, 8 patients showed severe psychological distress, 4 showed moderate distress and 9 showed no distress. The GSRS score was 34 (17-43) and the PGWBI was 64 (48-87), with a significant correlation between the 2 indexes (rho = -.58, P = .006). At 6 months, 3 patients had severe psychological distress, 5 had moderate distress, 9 showed no distress and 4 showed psychological well-being. The GSRS score at 6 months was 13 (8-17) and the PGWBI was 83 (68-95) (P < .05 compared with baseline data for the 3 indicators). The 6 axes of the PGWBI showed significant improvement. At 6 months, no correlation was found between the GSRS and PGWBI. Conclusions: Patients with celiac disease have psychological alterations whose intensity is relted to gastrointestinal symptoms.
