Assessment of serum inflammatory parameters in RRMS and SPMS patients.

OBJECTIVES: Multiple sclerosis (MS) is a chronic autoimmune inflammatory disease. Patients with relapsing-remitting MS (RRMS) and secondary progressive MS (SPMS) differ in their responses to treatment; therefore, the correct diagnosis of the particular type of MS is crucial, and biomarkers that can differentiate between the forms of MS need to be identified. The aim of this study was to compare the levels of inflammatory parameters in serum samples from patients with RRMS and SPMS. METHODS: The study group consisted of 60 patients with diagnosed MS. The patients were divided into RRMS and SPMS groups. In the RRMS patients, the usage of disease-modifying treatment was included in our analysis. The serum levels of inflammatory parameters were evaluated. RESULTS: The serum levels of BAFF, gp130 and osteopontin were significantly higher in SPMS patients than in RRMS patients. The serum levels of BAFF correlated with age in both RRMS and SPMS patients. The serum levels of MMP-2 were significantly higher in RRMS patients than in SPMS patients and correlated with the number of past relapses. The serum levels of IL-32 were significantly higher in RRMS treatment-naïve patients than in RRMS patients treated with disease-modifying therapy. DISCUSSION: Significant differences were found in BAFF, gp130, MMP-2 and osteopontin levels between RRMS and SPMS patients. Serum IL-32 levels were statistically lower in RRMS patients treated with disease-modifying therapy than in treatment-naïve patients.

Headache in Multiple Sclerosis: A Narrative Review.

Background: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disorder of the central nervous system characterized by autoimmune-mediated damage to oligodendrocytes and subsequent myelin destruction. Clinical implications: Clinically, the disease presents with many symptoms, often evolving over time. The insidious onset of MS often manifests with non-specific symptoms (prodromal phase), which may precede a clinical diagnosis by several years. Among them, headache is a prominent early indicator, affecting a significant number of MS patients (50-60%). Results: Headache manifests as migraine or tension-type headache with a clear female predilection (female-male ratio 2-3:1). Additionally, some disease-modifying therapies in MS can also induce headache. For instance, teriflunomide, interferons, ponesimod, alemtuzumab and cladribine are associated with an increased incidence of headache. Conclusions: The present review analyzed the literature data on the relationship between headache and MS to provide clinicians with valuable insights for optimized patient management and the therapeutic decision-making process.

The level of cytokines in tears as a novel indicator of demyelinating diseases.

INTRODUCTION: A novel research objective is to identify new molecules in more readily accessible biological fluids that could be used in the diagnosis of multiple sclerosis (MS) and other demyelinating disorders. AIM: To compare the level of selected cytokines in tears between patients with MS or other demyelinating disorder and healthy controls. MATERIAL AND METHODS: 84 patients with diagnosed MS during remission or with other demyelinating disease of the CNS and 70 healthy controls were enrolled in the study. Tears were collected without any stimulation and stored till the day of assessment. The concentration of selected cytokines was measured by the Bio-Plex Pro Human cytokine screening panel 27 cytokines assay according to the manufacturer's instructions. Statistical analysis was performed with Statistica 13. RESULTS: IL-1b level was significantly lower in the study group compared to the control group [3,6 vs 8.71, p < 0.001]. The same pattern was observed for IL-6 [3,1 vs 5.26, p = 0.027] and IL-10 [1,7 vs 10.92, p < 0.001] (Table 1). In the study group, IL-1RA (p = 0.015), IL-5 (p = 0.04), IL-9 (p = 0.014), and IL-15 (p = 0.037) showed significant correlations with age. In the total sample, IL-1Ra (p = 0.016) and IFN-g (p = 0.041) were significantly correlated with age, while in the control group, IL-8 (p = 0.09), MIP-1a (p = 0.009), and RANTES (p = 0.031) showed significant correlations. CONCLUSIONS: Our results show that MS and other demyelination diseases lead to decrease in the overall level of cytokines in tears. Further research is needed to determine the role of tear fluid in the assessment of demyelinating disorders like MS.

Risk Factors for Psychiatric Disorders in Patients with Multiple Sclerosis-A Single-Center Study in the Polish Population.

Aim: The aim of this study was to determine the prevalence of mental disorders in a group of patients with multiple sclerosis (MS) during outpatient treatment. Additionally, an attempt was made to assess the influence of parameters related to patients and their clinical status on the prevalence of mental disorders. Materials and Methods: This study was conducted between 2017 and 2018 in a group of 103 patients with MS who underwent treatment at the Outpatient Clinic of Neurology at the Clinical Hospital No. 1 in Zabrze, Poland. Sociodemographic data were collected, and the course of the underlying disease and comorbidities underwent assessment. The Mini International Neuropsychiatric Interview (MINI) and psychiatric examination were used to assess the occurrence of mental disorders. Results: In this study, female subjects accounted for 67.96% of patients (mean age: 43 years). Of all patients, 67% of subjects were clinically diagnosed with mental disorders during their lifetime. The results of the MINI Questionnaire showed that 33% of MS patients had a history of a major depressive episode, while 8.7% of patients met the criteria for a depressive episode. The same number of patients were treated for recurrent depressive disorders. Generalized anxiety disorder was diagnosed in 10.7% of patients, agoraphobia in 8.7% and panic disorder in 7.8%. Most patients (94.2%) had a low risk of suicide, according to the MINI Questionnaire. This study did not show a significant influence of age, sex, duration of MS symptoms or severity of symptoms as expressed by the Expanded Disability Status Score (EDSS) on the prevalence of mental disorders (p = 0.05). However, a significantly higher median EDSS score was found in patients with a history of mental disorders (p = 0.03). Additionally, a significant negative correlation was found between having a family and a psychiatric diagnosis (p = 0.01). A statistically significant negative correlation was found between the level of education and the suicide risk as assessed by the MINI Questionnaire (p = 0.03). Conclusions: This study showed a high prevalence of mental disorders in patients with MS, of which depressive episodes and anxiety disorders were the most commonly reported. There may exist a relationship between the degree of disability of MS patients and a higher prevalence of mental disorders. Patients with MS who do not have a family may be more susceptible to mental disorders. In turn, patients with a lower level of education may show a higher risk of suicide. This suggests the need for psychological and psychiatric support for patients with MS, with particular consideration given to those who are alone, those with more severe disability and patients with a lower level of education.

Analysis of seroconversion following COVID-19 vaccination among multiple sclerosis patients treated with disease-modifying therapies in Poland.

CLINICAL RATIONALE FOR THE STUDY: The rapid spread of SARS-CoV-2 throughout the world has highlighted the importance of vaccinations to control the pandemic and to protect people at risk for severe disease courses. Disease-modifying therapies (DMT) in multiple sclerosis (MS), whether immunomodulatory or immunosuppressive, may affect the immune response. Therefore, the question arose as to whether these vaccinations would be effective. AIM OF THE STUDY: We planned a study to assess the immune response to SARS-CoV-2 vaccines by type of therapy. MATERIAL AND METHODS: Participants were recruited from 14 Polish MS centres. The data was obtained by neurologists using a questionnaire. We collected data on 353 MS patients (269 females, 84 males) who received complete primary SARS-CoV-2 vaccination. All persons with MS (PwMS) were treated with disease-modifying therapies. RESULTS: 305 out of 353 PwMS (86.4%) were positive for IgG Abs against SARS-CoV-2 S domain S1 Ag after vaccination. A strong immune response was noted in 129 PwMS (36.5%). The rate of seroconversion after SARS-CoV-2 vaccination in PwMS who received immunomodulatory DMTs (interferon beta, glatiramer acetate, teriflunomide, dimethyl fumarate, natalizumab) was 91.5%, in PwMS receiving immune reconstruction therapy (alemtuzumab, cladribine) was 92%, and in immunosuppressive DMTs (fingolimod, ocrelizumab), the seroconversion rate was 59%. CONCLUSIONS AND CLINICAL IMPLICATIONS: Our study shows that, in PwMS receiving immunomodulatory therapy, the immune response to vaccination is generally excellent. Even in immunosuppressive patients, seroconversion is satisfactory.

Sense of happiness in Polish patients with multiple sclerosis.

INTRODUCTION: Happiness is crucial to patient well-being and their acceptance of their disease. The aim of this study was to assess the sense of happiness in persons with multiple sclerosis (PwMS), compare it to the level of happiness in patients with other neurological conditions, and determine which factors affect the sense of happiness in PwMS. MATERIAL AND METHODS: Five hundred and eighty-nine PwMS and 145 control subjects (post-stroke patients with chronic pain syndromes and neuropathies) were included in the study. Due to the differences between the groups in terms of demographic variables, an adjusted group of PwMS (n = 145) was selected from the entire group of PwMS. All patients were assessed using the Oxford Happiness Questionnaire (OHQ), the Satisfaction with Life Scale (SLS), and the Family APGAR Questionnaire. Based on regression analysis, the study examined which variables affected the level of happiness in the groups. RESULTS: Analysis of the OHQ scores showed that PwMS had a lower sense of happiness compared to the control group in the overall score [113.21 (25-42) vs. 119.88 (25-49), respectively; p = 0.031] and the subscales (OHQ subscale 1 - 54.52 vs. 57.84, respectively; p = 0.027; subscale 2 - 35.61 vs. 37.67; respectively; p = 0.044). Based on linear regression analysis, life satisfaction (ß = 0.40; p < 0.001), positive orientation (ß = 0.32; p < 0.001), and primary education (ß = 0.08; p = 0.009) were the most significant predictors of a higher level of happiness in PwMS. Similar results were found in the control group. CONCLUSIONS: The sense of happiness in PwMS was lower than in patients with other conditions. The most important factors influencing happiness included life satisfaction and positive orientation. Influencing these predictors should be the aim of psychological interventions, especially in patients with a reduced sense of happiness.

The Comparison of the Selected Parameters of Brain Injury and Interleukins in the CSF in Patients Diagnosed De Novo with RRMS Compared to the Control Group.

BACKGROUND: Multiple sclerosis (MS) is a chronic autoimmune disorder affecting the central nervous system (CNS). Due to the different phenotypes of the disease and non-specific symptoms of MS, there is a great need for a validated panel of biomarkers to facilitate the diagnosis, predict disease progression, and evaluate treatment outcomes. METHODS: We determined the levels of the parameters of brain injury (NF-H, GPAF, S100B, and UCHL1) and the selected cytokines in the cerebrospinal fluid (CSF) in 101 patients diagnosed de novo with RRMS and 75 healthy controls. All determinations were made using the Bio-Plex method. RESULTS: We found higher levels of NF-H and GFAP in the relapsing-remitting multiple sclerosis (RRMS) group compared to the controls. The concentrations of both molecules were significantly increased in patients with Gd+ lesions on brain MRI. The level of S100B did not differ significantly between the groups. UCHL1 concentrations were higher in the control group. We found some correlations between the selected cytokines, the levels of the parameters of brain injury, and the time from the first symptoms to the diagnosis of MS. CONCLUSIONS: The role of the above molecules in MS is promising. However, further research is warranted to define their precise functions.

A comparison of serum inflammatory parameters in progressive forms of multiple sclerosis.

INTRODUCTION: Multiple sclerosis (MS) is a chronic, inflammatory demyelinating disease of the central nervous system. Primary progressive MS (PPMS) is diagnosed in approximately 10-15 % of MS patients. Disease-modifying therapies (DMT) are less effective in modifying the course of progressive types of MS. It seems that inflammatory processes differ in the MS subtypes. OBJECTIVES: The objective of this study was to assess differences in the inflammatory parameters between PPMS and other courses of MS. MATERIALS AND METHODS: A total of 84 subjects were included in the study. The study group was divided according to the course of MS into the following categories: PPMS (n = 24); SPMS-secondary progressive multiple sclerosis (n = 14); RRMS-relapsing-remitting multiple sclerosis (n = 46). PPMS patients were further divided into treated with ocrelizumab and treatment-naive groups. The concentrations of serum inflammatory parameters were evaluated. RESULTS: PPMS and SPMS significantly differed in the serum levels of sCD30, gp130, sIL-6R alpha, osteopontin, pentraxin-3 and sTNF-R1. The serum concentrations of IFN-alpha2, IL-10, IL-20, IL-29 and osteopontin significantly differed between PPMS and RRMS. The serum levels of BAFF, IL-19, IL-20, pentraxin-3, s-TNF-R1 and s-TNF-R2 significantly differed between PPMS treated with ocrelizumab and treatment-naive. CONCLUSION: Although inflammatory processes take part in the pathogenesis of all types of MS, they differ between MS courses. Serum inflammatory parameters seem to be promising biomarkers in helping to differentiate courses of MS, and in assessing reactions to DMT treatment. Further investigations on their usage are required.

OCRELIZUMAB THERAPY IN PATIENTS WITH ANTI-HBC ANTIBODIES - A PRELIMINARY STUDY.

OBJECTIVE: Aim: Multiple sclerosis (MS) is a chronic inflammatory neurodegenerative disease resulting in cognitive impairment, physical disabilities, and neurological symptoms. Ocrelizumab is an effective drug used in MS treatment. However, it causes a risk of hepatitis B reactivation in anti-HBc positive patients. We describe the impact of entecavir and tenofovir on HBV reactivation during treatment with ocrelizumab. PATIENTS AND METHODS: Materials and methods: Our study included eight patients (aged 18-70 years) with positive anti-HBc antibodies who were diagnosed with MS based on the 2017 McDonald criteria. The subjects were treated with ocrelizumab and were given anti-HBV prophylaxis with nucleoside analogs. The mean time from the beginning of therapy with nucleoside analogs to the initiation of ocrelizumab treatment was 27.5 days. Patients were administered ocrelizumab and none of them was diagnosed with HBV reactivation. RESULTS: Results: None of the laboratory parameters worsened. No severe adverse effects were observed. These results suggest that entecavir and tenofovir are effective in HBV reactivation prophylaxis. Additionally, positive anti-HBc antibodies do not rule out treatment with ocrelizumab. CONCLUSION: Conclusions: In patients with positive anti-HBc antibodies, nucleoside analogs, such as entecavir or tenofovir, should be administered before ocrelizumab administration to reduce the risk of viral reactivation. Further studies on simultaneous treatment with ocrelizumab and nucleoside analogs are required to confirm our findings.

Cladribine tablets for highly active relapsing-remitting multiple sclerosis in Poland: a real-world, multi-centre, retrospective, cohort study during the COVID-19 pandemic.

INTRODUCTION: Treatment with cladribine tablets is indicated in highly active relapsing-remitting multiple sclerosis (RRMS). Cladribine tablets proved safe and effective in the pivotal CLARITY trial, but that trial included primarily treatment-naïve patients. In clinical practice however, cladribine tablets are often given to patients who have failed other treatments. Therefore, this study investigated the real-world safety and efficacy of cladribine tablets. MATERIAL AND METHODS: We gathered data from nine MS clinical centres across Poland for patients with RRMS who started treatment with cladribine tablets from December 2019 to June 2022. RESULTS: We enrolled 140 patients, with follow-up data available for 136 in year 1 and for 66 in year 2. At baseline, the mean age was 35.6 years, mean disease duration was 7.3 years, median EDSS score was 2.5, and 94% of patients were treatment- -experienced. Thirty-nine patients (27.9%) had undergone COVID-19, and 94 (67.1%) were vaccinated against COVID-19. The annualised relapse rate (ARR) decreased from 1.49 at baseline to 0.33 in year 1 (p < 0.001) and to 0.25 in year 2 (p < 0.001). The percentage of relapse-free patients increased from 11.5% at baseline to 70.2% in year 1 and 82.1% in year 2. The percentage of patients with active lesions decreased from 91.4% at baseline to 36.2% in year 1 and 18.2% in year 2. EDSS score remained stable or improved in 83.7% of patients in year 1 and 89.6% in year 2. No evidence of disease activity (NEDA-3) was achieved in 42.7% of patients in year 1 and 66.7% in year 2. Only one patient (0.72%) had grade 4 lymphopenia and 21 (15.1%) had grade 3 lymphopenia. Varicella zoster virus infections occurred in three patients. Eight patients discontinued treatment with cladribine: five due to inefficacy, one due to lymphopenia, and two due to a personal decision. CONCLUSIONS: Cladribine tablets proved safe and effective in a real-world cohort of treatment-experienced patients. However, the efficacy measures improved to a lesser extent in our cohort than in the pivotal clinical trial, which is probably due to a higher proportion of treatment-experienced patients in our cohort.

Course of therapy in patients with active relapsing-remitting multiple sclerosis despite first-line treatment.

Purpose: Treatment of patients with relapsing-remitting multiple sclerosis (RRMS) in Poland begins with first-line therapy; however, the treatment often fails. The aim of this study was to investigate the course of first-line treatment in patients who, despite experiencing an active course of the disease, did not receive more efficacious treatment due to the existing criteria in the drug program. Methods: The study included 139 patients from 45 treatment centers. Medical data concerning the course of treatment were collected with the use of specific forms. Results: The most frequently used drugs were ß-interferons, and treatment was initiated with these drugs in most cases; however, administration of dimethyl fumarate was also common. The median treatment duration was 30.9 months, with the longest treatment duration observed for ß-interferons. The most common reason for therapy switching or termination was treatment failure. Conclusions: First-line therapy in the studied population was based mainly on ß-interferons and dimethyl fumarate. For most medications, the discontinuation of therapy or drug switching were very common and the main reason was total or partial treatment failure. These observations suggest the need for earlier implementation of more effective treatment, based on drugs with high efficacy, in the study population.

Evaluation of antioxidant parameters of multiple sclerosis patients' serum according to the disease course.

INTRODUCTION: Multiple sclerosis (MS) is a chronic, demyelinating disease of the central nervous system. Its clinical courses are clinically isolated syndrome (CIS), relapsing remitting (RRMS), secondary progressive (SPMS), and primary progressive (PPMS). The differentiation of MS types is crucial for adequate treatment. OBJECTIVES: To evaluate antioxidant parameters of MS patients' serum according to MS type. MATERIALS AND METHODS: The study included 84 patients diagnosed with MS. The study group was divided into three subgroups corresponding to MS courses RRMS, SPMS, and PPMS. Sulfhydryl groups (SH), ceruloplasmin (CER), and superoxide dismutase (SOD) and its isoforms were identified in study participants' sera. RESULTS: CuZnSOD levels were significantly higher in SPMS patients than in PPMS patients, but there was no difference between SMPS and treatment-naive PPMS patients. MnSOD activity was significantly lower in SPMS patients than in PPMS patients. Our results show that SH levels were decreased in SPMS patients compared with RRMS patients, but this difference was significant only for male participants. SH concentration was reversely correlated with age, BMI, disease duration, EDSS, and in smoking patients with pack-years. CER serum levels waere elevated in SPMS patients compared with RRMS patients, but this difference was significant only for male participants. Our results show correlation between CER and EDSS levels. CONCLUSION: Oxidative stress plays a limited role in all disease stages, particularly in smokers as a confounding factor.

Cognitive and emotional support for the family of a person with frontotemporal degeneration - with particular consideration given to a minor. / Wsparcie poznawcze i emocjonalne rodziny osoby ze zwyrodnieniem czolowo-skroniowym ­ ze szczególnym uwzglednieniem dziecka niepelnoletniego.

The diagnosis of frontotemporal degeneration changes the entire family, being an unexpected and emotionally burdening experience for all the individuals in the family. Confrontation with problems that are diametrically different from those that occur in the family system without a person with a major neurocognitive disorder requires the development of new coping strategies. If these coping mechanisms are to be useful, they should undergo successive modifications that consider the progression of the neurodegenerative disease and the dynamics of the family system. Providing the information on different aspects of this group of diseases is the basic form of supporting families with frontotemporal degeneration. Growing up in the family with a parent affected by frontotemporal degeneration is a crucial, though non-normative, developmental experience of a child. It results in an irreversible loss of the existing relationship and the necessity to form another relationship with an affected parent. The paper focuses on providing support for a minor. Graphic medicine can be a support tool, which combines verbal communication with graphics, and, as a result, it provides knowledge on health problems and also creates the possibility of expressing emotions triggered by the presence of the disease in the family.

Multiple sclerosis and autoimmune diseases - a case control study.

INTRODUCTION: Multiple sclerosis (MS) is one of the most common autoimmune diseases worldwide, and various autoimmune comorbidities have been reported with MS. The aim of this study was to estimate the prevalence of autoimmune disease comorbidity in patients with MS and their relatives in a Polish population. MATERIAL AND METHODS: In this retrospective multicentre study, we investigated a group of patients with MS, and their relatives, in terms of age, gender, and the presence of simultaneous autoimmune diseases such as Graves's Disease, Hashimoto's thyroiditis, type 1 diabetes mellitus, myasthenia gravis, psoriasis, ulcerative enteritis, Crohn's Disease, coeliac disease, rheumatoid arthritis, autoimmune hepatitis and systemic lupus erythematous. RESULTS: This study included 381 patients with MS, of whom 52.23% were women. 27 patients (7.09%) had at least one autoimmune disease. The most common comorbidity was Hashimoto's thyroiditis (14 patients). 77 patients (21.45%) had relatives with an autoimmune disease, of which the most common was Hashimoto's thyroiditis. CONCLUSIONS: Our study revealed that the probability of autoimmune diseases co-occurring in patients with MS, and in their relatives, is higher and we found the greatest risk to be for Hashimoto's thyroiditis.

COVID-19 and autoimmune diseases of the nervous system - an update.

INTRODUCTION: Due to a similar pathomechanism, COVID-19 infection may significantly affect the course of autoimmune diseases (AIDs). In our review, we aimed to assess the severity of SARS-CoV-2 infection, response to treatment, and the impact of COVID-19 infection on the course of the underlying disease in patients with neuroimmune diseases. STATE OF THE ART: In the time of the COVID-19 pandemic, it was important to determine the influence of COVID-19 infection on the course of autoimmune diseases due to the weakened immune system and immunosuppressive therapies. CLINICAL IMPLICATIONS: Many reports have indicated that in patients with AIDs, the existence of the disease is not associated with a worse prognosis in the course of the viral infection. Patients in advanced stages of the disease, elderly patients, and those with comorbidities are at risk of more frequent hospitalisations and higher mortality in the course of COVID-19. Moreover, some drugs used in AIDs have been tested for their efficacy in SARS-CoV-2 infection. Episodes of newly diagnosed myasthenia gravis, Guillain-Barré syndrome, acute disseminated encephalomyelitis (ADEM), and neuromyelitis optica spectrum disorder (NMOSD) secondary to COVID-19 or vaccination have also been reported. Vaccination against this pathogen is highly recommended in most patients with AIDs. FUTURE DIRECTIONS: Despite many studies on the association between COVID-19 and neuroimmune diseases, more specific data is needed. The approach to patients with AIDs should be individual, since many issues remain unresolved despite the long-lasting pandemic.

Role of Microglial Cells in the Pathophysiology of MS: Synergistic or Antagonistic?

Many studies indicate an important role of microglia and their cytokines in the pathophysiology of multiple sclerosis (MS). Microglia are the macrophages of the central nervous system (CNS). They have many functions, such as being "controllers" of the CNS homeostasis in pathological and healthy conditions, playing a key role in the active immune defense of the CNS. Macroglia exhibit a dual role, depending on the phenotype they adopt. First, they can exhibit neurotoxic effects, which are harmful in the case of MS. However, they also show neuroprotective and regenerative effects in this disease. Many of the effects of microglia are mediated through the cytokines they secrete, which have either positive or negative properties. Neurotoxic and pro-inflammatory effects can be mediated by microglia via lipopolysaccharide and gamma interferon. On the other hand, the mediators of anti-inflammatory and protective effects secreted by microglia can be, for example, interleukin-4 and -13. Further investigation into the role of microglia in MS pathophysiology may perhaps lead to the discovery of new therapies for MS, as recent research in this area has been very promising.

SARS-CoV-2 neurotropism and other possible causes of olfactory disorders in COVID-19.

Coronavirus disease 2019 (COVID-19) is an acute infectious respiratory disease (AIRD) caused by infection with the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first cases were diagnosed and reported in Wuhan, central China, in November 2019. The disease initially occurred locally. However, the number of infected individuals increased dynamically and spread worldwide. The most common symptoms of the SARS-CoV-2 infection include malaise, fever, dry cough and dyspnoea. Over time, reports of new COVID-19 symptoms included taste and smell disorders. A potential cause of these disorders is related to neurotropism, i.e. the affinity of SARS-CoV-2 to the nervous system. Angiotensin-converting enzyme 2 receptor is essential in the pathogenesis of SARS-CoV-2 infection. The receptor is found in many tissues and organs, including the olfactory epithelium, neurons and neuroglial cells. Another potential cause is neuroinvasiveness, i.e. the ability of the virus to invade the central nervous system, and thereby damage its structures. As a result, olfactory disorders may occur. Other concepts, such as the inflammatory response of the body and the concept of stroke or damage to olfactory supporting cells, are also considered.

The comparative analysis of selected interleukins and proinflammatory factors in CSF among de novo diagnosed patients with RRMS.

OBJECTIVES: Cytokines play a key role in neuroinflammation, which is present in every subset of multiple sclerosis (MS). The aim of the study was to assess levels of selected interleukins and proinflammatory factors in cerebrospinal fluid (CSF) among patients diagnosed with relapsing-remitting multiple sclerosis (RRMS). METHODS: One hundred eighteen patients diagnosed de novo with RRMS were enrolled in the study. We analysed the relationships between selected cytokines' levels depending on the age at diagnosis, time from the first symptoms to diagnosis and presence of MRI lesions. RESULTS: Among the study group the levels of IL-5 and IL-13 increased with the age at the diagnosis of MS. The concentration of IL-10 was lower in group of patients over the age of 35. The levels of IFN-γ, TNF-α, IL-5, IL-10 and IL-15 increased with the longer time from the first symptoms to diagnosis. Positive correlations were found between the levels of IL-2 and IL-12, IL-17, IL-4, IL-1RA as well as IL-1 and IL-4, IL-17. The concentration of IL-5 correlated positively with IL-4, IL-9 and IL-13. The level of IL-10 increased with IL-6 and IL-9 concentrations. A negative correlation was found for IL-10 and IL-4. In turn, between IL-13 and both IL-5 and IL-9, the relationship was positive. The level of IL-2 was significantly higher among patients without gadolinium-enhanced (Gd(+)) MRI lesions. CONCLUSIONS: The results of the study provide new insight into the role of selected molecules in the development of inflammation in MS. It might be crucial in planning the most adequate immunomodulatory therapy.

Common pathomechanism of migraine and depression. / Wspólny patomechanizm migreny i depresji.

Migraine and depression often coexist and constitute an important clinical problem. Both disorders are associated with the necessity of chronic treatment, and their mutual coexistence contributes to the phenomenon of drug resistance. Influencing the functioning of patients, they also cause numerous social consequences - affecting the quality of life and achievement of personal goals of patients. This review presents factors that may explain the common pathomechanisms of depression and migraine. Structural and functional disturbances of the central nervous system (CNS), disturbances in the neurotransmitter systems, inflammatory theories, hormonal disturbances, as well as a possible genetic basis were taken into account. Due to the fact that both depression and migraine have a multifactorial etiology and at the present stage of scientific research it is difficult to clearly determine which factor is the most important, such a broad overview has been presented. It is also difficult to determine which of the above-mentioned factors, well documented in international studies, only coexist, and which of them may have a cause-and-effect relationship in the described disorders. Further research into the comorbidity and causes of migraine and depression seems to be worth considering.

Religious meaning system and life satisfaction: the mediating role of meaning in life among Polish people with multiple sclerosis.

Introduction: The complexity of the associations between religiosity and indicators of well-being suggests the presence of a mediating mechanism. Previous studies indicate that religion may influence subjective well-being because it helps to find meaning and purpose. Therefore, the aim of our study was to examine the mediating role of the presence and search dimensions of meaning in life in the relationship between religious meaning system and life satisfaction in patients with multiple sclerosis (MS). Methods: This cross-sectional study included 600 MS patients recruited from Poland who completed the Satisfaction with Life Scale (SWLS), the Religious Meaning System Questionnaire (RMS) and the Meaning in Life Questionnaire (MLQ). Model 6 of Hayes PROCESS was used to test the hypotheses. Results: The results of our research indicate that there was a significant indirect effect of religious meaning system on life satisfaction through the presence of meaning in life. The specific indirect effect of religious meaning system on life satisfaction through searching for meaning in life was not significant. Discussion: The results of our study are relevant because they show that religion as a meaning system is positively related to the presence of meaning in life, which in turn positively predicts life satisfaction. This is particularly important in the case of incurable illness, where finding meaning in life is one of the natural stages of adaptation. By incorporating these findings into mental health practice, professionals can enhance the holistic well-being of people coping with MS and contribute to a more comprehensive and effective approach to mental health care.
