Background: Inflammatory processes have been proposed in the pathophysiology of ischemic stroke. The present study was designed to evaluate the relationship between tumor necrosis factor-alpha (TNF-α), interleukin 6 (IL-6), IL 1 beta (IL-1β), and high sensitivity C-reactive protein (hsCRP) with the prognosis and functional outcome in patients with less severe ischemic stroke. Methods: We measured the level of IL-1β, IL-6, hsCRP, and TNF-α on days 1 and 5 after stroke onset by enzyme-linked immunosorbent assay (ELISA). The infarct volume was assessed using Alberta Stroke Program Early CT Score (ASPECTS) and posterior circulation ASPECTS (pcASPECTS) score in brain computed tomography (CT) scan and magnetic resonance imaging (MRI). The severity of stroke was assessed by applying the National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Scale (MRS) in 24 hours on day 5and after 3 months from stroke onset. Good outcome was defined as the third month MRS ≤ 2. The association of inflammatory markers and the course of stroke symptoms over time was examined. Results: Forty-four first-ever stroke patients without concurrent inflammatory diseases with a mean age of 65 years were included. The mean NIHSS and MRS in admission time were 6.5 ± 3.5 and 3.07, respectively. The day 1 and the day 5 levels of IL-1β, IL-6, hsCRP, and TNF-α were not significantly different in good and poor outcome groups (all P-values > 0.05). In addition, they were not significantly associated with the ASPECTS, pcASPECTS, and changes of NIHSS and MRS over time. Conclusion: The levels of hsCRP, IL-1β, IL-6, and TNF-α are not reliable predictors of functional outcomes in patients with less severe acute ischemic stroke (AIS).

Background: Subclinical atherosclerosis is the asymptomatic phase of carotid atherosclerosis, and its early diagnosis is important to prevent cerebrovascular diseases. Although the vitamin D plays a role in the structure of vessels, the association between the serum level of vitamin D and subclinical atherosclerosis has not been well-studied. We aimed to investigate the association between serum vitamin D level and carotid artery intima-media thickness (CIMT) in Iranian population. Methods: One hundred individuals with the age range from 20 to 50 years with no history of cardiovascular risk factors were selected for the analysis. Measurements of serum25-hydroxyvitamin D3 [25(OH) D3] concentration and CIMT were made. Confounding factors such as diabetes, hypertension (HTN), smoking, alcohol, tobacco, dyslipidemia, cardiovascular disease (CVD), high body mass index (BMI), history of drug intake especially calcium, vitamin D, statins, and anti-hypertensive drugs were considered and then excluded from our study. Results: The mean serum vitamin D level was 15.55 ± 0.42 ng/ml, whereas in the increased intima-media thickness (IMT), it was 12.50 ± 9.50 ng/ml. 55% of the subjects were diagnosed with subclinical atherosclerosis (IMT ≥ 0.75 mm). Mean IMT was 0.74 ± 0.12 mm; however, it was higher (0.86 ± 0.30) in severe vitamin D deficiency group. The analysis showed an association between serum 25(OH) D3 level and CIMT (P = 0.002). 44% of those participants with subclinical atherosclerosis had also a severe vitamin D deficiency, while only 13% of normal people had a severe vitamin D deficiency. Also, a correlation was observed between severe vitamin D deficiency and the presence of plaque or higher IMT. Conclusion: Serum 25(OH) D3 level was inversely correlated with CIMT in our investigated subjects with no cardiovascular risk factor.

Background: Multiple sclerosis (MS) is a common autoimmune inflammatory disease in the central nervous system (CNS) without exact pathology. Environmental factors such as infections have a causal or protective role in MS. Helicobacter pylori (HP) is one of the infections in digestive diseases and previous studies reported controversial findings of this infection role in MS. So, we conducted this study to assess the frequency of HP infection in patients with MS in comparison to the healthy population. Methods: This cross-sectional study was undertaken between 2015 and 2019. 191 participants including 58 patients with clinically isolated syndrome (CIS), 57 patients with relapsing-remitting MS (RRMS), 39 patients with secondary progressive MS (SPMS), and 39 age- and sex-matched healthy controls (HCs) were tested for the presence of HP immunoglobulin G (IgG) and IgM antibodies (Abs) in their serum sample. Results: The frequency of HP IgG seropositivity in patients with SPMS was significantly higher than patients with CIS [Odds ratio (OR): 6.333, 95% confidence interval (CI): 2.522-15.906, P < 0.001], patients with RRMS (OR: 4.583, 95% CI: 1.842-11.407, P = 0.001), and HCs (OR: 8.485, 95% CI: 3.058-23.540, P < 0.001). We did not find a significant difference among other study groups regarding IgG seropositivity. No significant difference among groups regarding HP IgM seropositivity was evident. On univariate model, Expanded Disability Status Scale (EDSS) score (OR: 1.038, 95% CI: 1.038-1.460, P = 0.017) and SPMS (OR: 4.583, 95% CI: 1.842-11.407, P = 0.001) were predictor for HP IgG seropositivity. On multivariate model, only SPMS had higher risk for HP IgG seropositivity compared to RRMS (OR: 5.554, 95% CI: 1.327-23.253, P = 0.019). We did not find a significant association between clinical and demographic variables with HP IgM seropositivity. Conclusion: Based on our findings, progressive MS and HP infection may have association. Further longitudinal studies with large sample size are needed to determine the role of HP infection in MS.

Background: Migraine is a neurologic disorder. Although, based on previous evidence, migraine is related with inflammation and oxidative stress, its relationship with the inflammatory potential of the diet is still unknown. Thus, the aim of this study was to show the correlation between Dietary Inflammatory Index (DII) and severity and duration of migraine headache. Methods: In this cross-sectional study, 266 women who suffered from migraine, were included. Demographic and anthropometric data were collected form all participants. 147-item semiquantitative food frequency questionnaire (FFQ) was collected to assess dietary intake and consequently, DII scores were calculated. Migraine Disability Assessment (MIDAS) questionnaire, Visual Analog Scale (VAS), and a 30-day headache diary were also completed by each participant. Results: The DII score ranged between -4.22 and 5.19 and its median [interquartile range (IQR)] was 0.003 (-1.48-1.55). There was no meaningful association between age, occupation, physical activity (PA), weight, height, Body Mass Index (BMI), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR) and DII score classifications (P > 0.050). Subjects with more than 20 days of headache had higher DII score compared to those with less than 10 days per month [odds ratio (OR) = 1.60, 95% confidence interval (CI) = 1.12-2.08, P = 0.001]. There was no association between DII and migraine severity (VAS and MIDAS) in the crude and adjusted model of logistic regression. Although there was a significant association between headache duration and DII (P = 0.020), this relationship was not meaningful after adjusting for age, PA, BMI, and job status (OR = 0.53, 95% CI = 0.28-1.00, P = 0.052). Conclusion: The present study showed a direct association between headache frequency and DII. Nevertheless, any relationship was not found between headache duration or migraine severity and DII score. Future large and prospective studies are needed to explore the effect of inflammatory potential of diet in migraine characteristics.

Background: Headache is among the most common disabling neurologic disorders. We measured quality of life in chronic migraine (CM) and episodic migraine (EM), stratified by medication overuse headache (MOH) and presence of aura. Methods: In this observational study, conducted from January 2016 to December 2018, adult patients referred to the tertiary headache clinic of Sina Hospital in Tehran, Iran, who met International Classification of Headache Disorders, 3rd Edition-beta (ICHD-3 β) criteria for migraine were classified to EM and CM subtyped based on presence of aura and MOH. Validated Farsi versions of Migraine Disability Assessment Scale (MIDAS) and 6-item Headache Impact Test (HIT-6) questionnaires were used. Results: A total of 2454 patients (1907 women) were enrolled from which 1261 (51.4%) patients had EM and 1193 (48.6%) had CM, while 908 subjects (37.0%) had MOH, of whom 890 (98.0%) had CM. Median scores of MIDAS and HIT-6 were significantly higher in patients with CM compared to EM sufferers. Chronic migraineurs with MOH had a significantly higher median score of MIDAS and HIT-6 compared to patients with non-MOH CM. Also, there was a moderate positive correlation between MIDAS (disability) and HIT-6 scores (impact on patients’ life) and a moderate correlation between HIT-6 and pain severity. Conclusion: The results of this study confirm that CM and MOH are associated with a higher headache-related disability and impact on life compared to EM. Therefore, treatment goals in prevention of MOH and migraine transformation warrant higher quality of life in patients with migraine.
