Toxoplasma gondii and multiple sclerosis: a population-based case-control seroprevalence study, Central Anatolia, Turkey.

BACKGROUND: Toxoplasma gondii, an obligate intracellular parasite, is prevalent in various mammalian species, as well as certain avian, reptilian, and cold-blooded organisms. While immunocompetent individuals generally remain asymptomatic, immunocompromised individuals may experience severe and life-threatening conditions. Multiple sclerosis (MS), a chronic autoimmune disease affecting the central nervous system (CNS), is characterized by inflammation, demyelination, and axonal damage. Despite extensive research, the etiology and pathogenesis of MS remain incompletely understood. Given the strong affinity of T. gondii for the CNS, researchers have explored the potential association between T. gondii and autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, type 1 diabetes, and MS. This study aimed to investigate the possible relationship between MS and T. gondii. METHODS: A population-based incident cohort of MS patients in Sivas, Turkey, was used to randomly select MS patients. Age- and sex-matched controls were also randomly selected from the general population. A total of 182 MS patients and 182 controls were included in the study. Clinical and socio-demographic variables were recorded using a structured questionnaire. Blood samples were collected from MS patients, and Toxoplasma IgG and IgM antibodies were measured using the enzyme-linked immunosorbent assay technique. RESULTS: Anti-Toxoplasma IgG antibodies were detected in 78 cases (42.9%) and 73 controls (40.1%) (p>0.05). Age, female sex, and consumption of raw meat were identified as risk factors for toxoplasmosis in both MS patients and controls. CONCLUSION: In contrast to previous studies, this study did not find a significant difference in T. gondii seropositivity between the control group and MS patients. Further investigations are recommended to elucidate the precise relationship between MS patients and T. gondii.

Clinical and Demographic Characteristics and Two-Year Efficacy and Safety Data of 508 Multiple Sclerosis Patients with Fingolimod Treatment.

Introduction: Fingolimod is the first oral immunomodulatory treatment used as secondary care therapy in the treatment of multiple sclerosis for the last 10 years. The objective of our study is to reveal the experiences of the first generic fingolimod active ingredient treatment in different centers across Turkey. Method: The first generic fingolimod efficacy and safety data of patients followed-up in 29 different clinical multiple sclerosis units in Turkey were analyzed retrospectively. Data regarding efficacy and safety of the patients were transferred to the data system both before the treatment and on the 6th, 12th and 24th month following the treatment. The data were analyzed using the IBM SPSS 20.00. P value of <0.05 was considered to be statistically significant. Results: A total of 508 multiple sclerosis patients, 331 of whom were women, were included in the study. Upon comparing the Expanded Disability Status values before and after the treatment, a significant decrease was observed, especially at month 6 and thereafter. Since bradycardia occurred in 11 of the patients (2.3%), the first dose had to be longer than 6 hours. During the observation of the first dose, no issues that could prevent the use of the drug occured. Side effects were seen in 49 (10.3%) patients during the course of fingolimod treatment. Respectively, the most frequent side effects were bradycardia, hypotension, headache, dizziness and tachycardia. Conclusion: The observed results regarding efficacy and safety were similar to clinical trial data in the literature and real life data in terms of the first equivalent with fingolimod active ingredient.

The role of systemic immune inflammatory index in showing active lesion in patients with multiple sclerosis : SII and other inflamatuar biomarker in radiological active multiple sclerosis patients.

BACKGROUND: Multiple sclerosis (MS) has two pathophysiological processes, one inflammatory and the other degenerative. We investigated the relationship between active lesions on magnetic resonance imaging showing the inflammatory phase in MS patients and serum parameters that can be used as inflammatory biomarkers. Thus, we aim to detect the inflammatory period in clinical and radiological follow-up and to reveal the period in which disease-modifying treatments are effective with serum parameters. METHODS: One hundred eighty-six MS patients presented to our hospital between January 2016 and November 2021 and 94 age- and sex-matched healthy volunteers were recruited for our study. While 99 patients had active lesions on magnetic resonance imaging, 87 patients did not have any active lesions. Neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and monocyte/lymphocyte ratio (MLR) were determined. The SII (systemic immune inflammatory index) value was calculated according to the platelet X neutrophil/lymphocyte ratio formula. RESULTS: NLR, MLR, PLR and SII values were found to be statistically significantly higher in MS patients than in the control group. The NLR, MLR, PLR and SII were higher in the active group with gadolonium than in the group without active lesions. In addition, the cutoff values that we can use to determine the presence of active lesions were 1.53, 0.18, 117.15, and 434.45 for NLR, MLR PLR and SII, respectively. CONCLUSIONS: We found that all parameters correlated with radiological activity. In addition, we showed that we can detect the inflammatory period with high sensitivity and specificity with the cutoff value used for SII and PLR. Among these easily accessible and inexpensive evaluations, we concluded that SII, including the values in the PLR formula, can come to the fore.

Prevalence of multiple sclerosis in an urban population of Sivas province in Turkey

Background/aim: Multiple sclerosis (MS) is a common neurological disorder that can be a leading cause of nontraumatic disability in several countries. Recent reports have indicated a moderate to high risk of MS in European countries. In this study, we examined the prevalence of MS in a well-defined urban population of provincial center in Sivas Province in Turkey. Materials and methods: This study sampled all registered residents of urban areas of provincial center in Sivas Province in April 2017 and 2018 January. All the included patients met the McDonald 2010 criteria. Medical records were reviewed, including all available previously acquired magnetic resonance imaging data. All patients were subsequently subjected to neurologic examination to confirm the MS diagnosis. Results: We identified 21 possible MS patients, with MS diagnosis confirmed in 19. The prevalence of MS was 288 per 100,000 inhabitants. Conclusion: For future studies, these high ratio results can be used in regional and national comparisons to determine cofactors contributing to the high prevalence of MS in our region and can help health-decision makers to better plan healthcare policies to improve neurological services and awareness about multifaceted clinical presentations of MS.

Monocyte/high-density lipoprotein ratio predicts the mortality in ischemic stroke patients.

OBJECTIVE: The inflammatory process is a very important stage in the development and prognosis of acute ischemic stroke (AIS). The monocyte to high-density lipoprotein (HDL) ratio (MHR) is accepted as a novel marker for demonstrating inflammation. However, the role of MHR as a predictor of mortality in patients with AIS remains unclear. METHODS: We retrospectively enrolled 466 patients who were referred to our clinic within the first 24hours of symptom presentation and who were diagnosed with AIS between January 2008 and June 2016. Four hundred and eight controls of similar age and gender were also included. The patient group was classified into two groups according to 30-day mortality. The groups were compared in terms of monocyte counts, HDL, and MHR values. RESULTS: The patient group had significantly higher monocyte counts and lower HDL levels; therefore, this group had higher values of MHR compared to controls. Additionally, the monocyte count and MHR value were higher, and the HDL level was lower in non-surviving patients (p<0.001). The MHR value was also observed as a significant independent variable of 30-day mortality in patients with AIS (p<0.001). The optimum cut-off value of MHR in predicting the 30-day mortality for patients with AIS was 17.52 (95% CI 0.95-0.98). CONCLUSION: Our study demonstrated that a high MHR value is an independent predictor of 30-day mortality in patients with AIS.

The Effect of Eosinopenia on Mortality in Patients with Intracerebral Hemorrhage.

INTRODUCTION: Inflammation may determine the prognosis of intracerebral hemorrhage (ICH), which has high mortality and morbidity rates. Recent studies have increasingly demonstrated eosinopenia as a prognostic factor, particularly in bacteremia, chronic obstructive pulmonary disease, and myocardial and cerebral infarction. Nonetheless, its significance regarding the determination of prognosis in patients with ICH has not yet been clarified. MATERIALS AND METHODS: Our study included 296 patients who presented to our clinic within 24 hours of the onset of symptoms and who were diagnosed with ICH between January 2008 and June 2016, along with 180 age- and sex-matched controls. During their hospitalization, 120 of these 296 patients died. Patients and controls were compared in terms of neutrophil count/percentage and eosinophil count/percentage; these were also compared between nonsurviving and surviving patients. The significance of eosinopenia in predicting mortality was also evaluated. RESULTS: Patients had a significantly higher neutrophil count/percentage and a significantly lower eosinophil count/percentage than controls; these results were similar between nonsurviving and surviving patients (P < .001). Consequently, the patient group was divided into 4 subgroups depending on the presence of eosinopenia and/or neutrophilia. The mortality rate was highest (62%) in the group that had both eosinopenia and neutrophilia. Univariate and multivariate logistic regression analyses indicated that neutrophilia and eosinopenia were independent predictors of mortality in ICH (P = .002; P = .004) DISCUSSION: These results indicate that eosinopenia can occur in patients with ICH and that although the mechanism is unclear, eosinopenia is closely associated with mortality in these patients, particularly when accompanied by neutrophilia.

Severity and frequency of restless legs syndrome in patients with familial Mediterranean fever.

OBJECTIVE: Restless legs syndrome (RLS) is a common sensory motor disorder. RLS an urge to move the extremities that may be accompanied by dysesthesias, and significantly affects quality of life of affected patients. The frequency of RLS is higher in different systemic inflammatory diseases. Familial Mediterranean fever (FMF) is an inherited inflammatory disease characterized by attacks of polyserositis, arthritis, and fever. The prevalence of RLS in patients with FMF is unknown. This study aimed to evaluate the prevalence rate of RLS in a sample of patients with FMF and compare this prevalence with that of a matched normal population. METHOD: A total of 60 patients with FMF and 60 healthy controls were studied. All participants underwent a neurological examination. Diagnostic criteria as proposed by the International Restless Legs Syndrome Study Group (IRLSSG) were used to define RLS. The IRLSSG rating scale for the severity of RLS was applied to determine the severity of symptoms. RESULTS: The prevalence of RLS was not significantly different between patients and controls. Although the mean International Restless Legs Syndrome Rating Scale (IRLSRS) scores tended to be higher in patients compared with controls, this difference was not significant. When each item of the severity scale was compared between the two groups, significantly higher scores were found in some items of the IRLSRS in patients with FMF compared with controls. CONCLUSION: According to this result, RLS symptoms in patients with FMF were more frequent and lasted longer than those in controls.
