RESUMO
OBJECTIVE: Peginterferon ß-1a (PEG-IFN-ß-1a) is the most recent interferon beta formulation approved for treating relapsing-remitting multiple sclerosis (RRMS). We aim to describe the real-world utilization of PEG-IFN-ß-1a in RRMS and compare it with other injectable disease-modifying therapies (DMTs). PATIENTS AND METHODS: In this population-based study, we used 2015-2019 routinely collected healthcare data of the Campania region of Italy from National Healthcare System DMT prescriptions, inpatient and outpatient clinical records of hospitals in Campania, and the Federico II University MS clinical registry for a subset of patients. We included individuals with RRMS receiving new prescriptions of PEG-IFN-ß-1a [n=281; age = 38.8±12.3 years; females=70.5%; disease duration = 8.4±8.3 years; Expanded Disability Status Scale (EDSS) at baseline=2.0 (1.0-6.5)], glatiramer acetate [n=751; age = 46.0±11.4 years; females=67.1%; disease duration = 9.8±8.2 years; EDSS=4.0 (1.5-8.5)], and subcutaneous (SC) IFN-ß-1a [n=1,226; age = 39.7±11.7 years; females=66.5%; disease duration = 8.2±6.5 years; EDSS 2.5 (1.5-6.5)]. Adherence [medication possession ratio (MPR)], escalation to more effective DMTs, hospitalization rates and costs were measured. We used mixed-effect linear regression models (for adherence, hospitalization rates and costs) and Cox regression models (for escalation) to assess differences between PEG-IFN-ß-1a (statistical reference), glatiramer acetate, and SC IFN-ß-1a. All models included age, sex, previous treatment/untreated, year of treatment initiation, treatment duration, and adherence as covariates. RESULTS: Adherence was lower in glatiramer acetate (MPR = 0.91±0.1; Coeff=-0.11; p<0.01), and IFN-ß-1a (MPR = 0.92±0.1; Coeff=-0.08; p<0.01), compared with PEG-IFN-ß-1a (MPR = 1.01±0.1). The probability of escalating to more effective DMTs was higher for glatiramer acetate (14.9%; HR=4.09; p<0.01) and IFN-ß-1a (9.1%; HR=3.35; p=0.01), compared with PEG-IFN-ß-1a (4.9%). No differences in annualized hospitalization rates were identified between glatiramer acetate [annualized hospitalization rates (AHR) = 0.05±0.30; Coeff=0.02; p=0.31), IFN-ß-1a (AHR = 0.02±0.21; Coeff=0.01; p=0.97], and PEG-IFN-ß-1a (AHR = 0.02±0.24); however, monthly costs for MS admissions were higher for glatiramer acetate (49.45±195.27; Coeff=-29.89; p=0.03), compared with IFN-ß-1a (29.42±47.83; Coeff=6.79; p=0.61), and PEG-IFN-ß-1a (23.91±43.90). CONCLUSIONS: SC PEG-IFN-ß-1a and IFN-ß-1a were used in relatively similar populations, while glatiramer acetate was preferred in older and more disabled patients. PEG-IFN-ß-1a was associated with higher adherence and lower escalation rates toward more effective (and costly) DMTs.

BACKGROUND: Although multiple sclerosis (MS) Intimacy and Sexuality Questionnaire-19 (MSISQ-19) is a widely applied tool, no unique definition of sexual dysfunction (SD) based on its score exists. OBJECTIVE: To explore the impact of different MSISQ-19 cut-offs on SD prevalence and associated risk factors, providing relevant information for its application in research and clinical settings. METHODS: After defining SD according to two different MSISQ-19 cut-offs in 1155 people with MS (pwMS), we evaluated SD prevalence and association with sociodemographic and clinical features, mood status and disability via logistic regression. RESULTS: Depending on the chosen cut-off, 45% to 54% of pwMS reported SD. SD defined as MSISQ-19 score >30 was predicted by age (OR=1.01, p=0.047), cognition (OR=0.96, p=0.004) and anxiety (OR=1.03, p=0.019). SD defined as a score >3 on any MSISQ-19 item was predicted by motor disability (OR=1.12, p=0.003) and cognition (OR= 0.96, p=0.002). CONCLUSION: Applying different MSISQ-19 cut-offs influences both the estimated prevalence and the identification of risk factors for SD, a finding that should be considered during study planning and data interpretation. Preserved cognition exerts a protective effect towards SD regardless from the specific study setting, representing a key point for the implementation of preventive and therapeutic strategies.
RESUMO
BACKGROUND AND PURPOSE: The long-term impact of gadolinium retention in the dentate nuclei of patients undergoing administration of seriate gadolinium-based contrast agents is still widely unexplored. The aim of this study was to evaluate the impact of gadolinium retention on motor and cognitive disability in patients with MS during long-term follow-up. MATERIALS AND METHODS: In this retrospective study, clinical data were obtained from patients with MS followed in a single center from 2013 to 2022 at different time points. These included the Expanded Disability Status Scale score to evaluate motor impairment and the Brief International Cognitive Assessment for MS battery to investigate cognitive performances and their respective changes with time. The association with qualitative and quantitative MR imaging signs of gadolinium retention (namely, the presence of dentate nuclei T1-weighted hyperintensity and changes in longitudinal relaxation R1 maps, respectively) was probed using different General Linear Models and regression analyses. RESULTS: No significant differences in motor or cognitive symptoms emerged between patients showing dentate nuclei hyperintensity and those without visible changes on T1WIs (P = .14 and 0.92, respectively). When we tested possible relationships between quantitative dentate nuclei R1 values and both motor and cognitive symptoms, separately, the regression models including demographic, clinical, and MR imaging features explained 40.5% and 16.5% of the variance, respectively, without any significant effect of dentate nuclei R1 values (P = .21 and 0.30, respectively). CONCLUSIONS: Our findings suggest that gadolinium retention in the brains of patients with MS is not associated with long-term motor or cognitive outcomes.

Introduction: Disease modifying treatments are commonly used in the treatment of multiple sclerosis. As different opportunistic infections have been reported, concerns are also raised regarding the risk of invasive fungal infections.Areas covered: Both clinical trials and observational studies on safety and efficacy of diseases modifying treatment for multiple sclerosis were reviewed and data regarding the occurrence of invasive fungal infections were reported. Papers evaluating the following drugs were reviewed: rituximab, ocrelizumab, alemtuzumab, fingolimod, natalizumab, dimethyl fumarate, interferon, glatiramer acetate, cladribine, teriflunomide.Expert opinion: Overall, the occurrence of invasive fungal infections was low, with most infective events reported among patients treated with monoclonal antibodies and fingolimod. Aspergillosis and cryptococcal meningitidis were the most representative fungal infections. Although not common, these infections may be difficult to diagnose and their fatality rate is often high. For this reason, screening protocols for fungal infections must be implemented in the clinical practice when managing patients with MS.

The prevalence of trigeminal neuralgia (TN) in patients with Multiple Sclerosis (MS) is higher than in the general population and its management can be particularly challenging due to a number of reasons including high recurrence rates, lack of MS-specific treatment guidelines and uncertainties about pain pathophysiology. Aim of this cross-sectional, multicentre survey was to gather information on the current treatment modalities and options of MS-related TN across 23 Italian MS centres. Initial medical management (carbamazepine or oxcarbazepine) of MS-related TN was fairly homogeneous throughout Italian centres. The most commonly available surgical procedure was microvascular decompression, but the frequency and types of surgical procedures available locally differed considerably throughout MS centers, and were unavailable in one quarter of them. This survey reveals some of the issues that could hamper an optimal patient management and underlines the need for a consensus on MS-related TN to support health-care professionals in their approach to this challenging condition and to facilitate the development of local guidelines aimed at ensuring equity in access to care and treatment optimization.

In the last years, change in multiple sclerosis (MS) therapeutic scenario has highlighted the need for an improved doctor-patient communication in advance of treatment initiation in order to allow patient's empowerment in the decision-making process. AIMS: The aims of our project were to review the strategies used by Italian MS specialists to inform patients about treatment options and to design a multicentre shared document that homogenizes the information about disease-modifying treatment (DMTs) and the procedure of taking informed consent in clinical practice. RESULTS: The new resource, obtained by consensus among 31 neurologists from 27 MS Centres in Italy with the supervision of a medico-legal advisor, received the aegis of Italian Neurological Society (SIN) and constitutes a step toward a standardized decision process around DMTs in MS.

BACKGROUND: Dimethyl-fumarate (DMF) was effective and safe in relapsing-remitting multiple sclerosis (MS) in randomized clinical trials. We aimed to evaluate the efficacy and safety of DMF and factors related to drug response in real-life setting. METHODS: We analysed prospectively collected demographic and clinical data for patients treated with DMF in six multiple sclerosis (MS) centers from 2015 to 2017 in Campania region, Italy. We performed univariate and multivariate analyses to assess relationships between baseline parameters and DMF efficacy outcomes, Annualized Relapse Rate (ARR), Expanded Disability Status Scale (EDSS) progression and No Evidence of Disease Activity (NEDA-3) status. RESULTS: we analyzed data of 456 patients (67% female subjects, mean age 40 ± 12 years, mean disease duration 9 ± 9 years, mean treatment duration 18 ± 11 months, median EDSS 2.5, 0-8). Proportion of Naïve versus pretreated with other DMTs patients was 149/307 (32.7%), with 122 patients switching to DMF for disease activity (26.7%) and 185 for safety and tolerability issues (40.6%). During treatment with DMF, the annualized relapse rate was reduced by 75% respect to the pre-treatment ARR [incidence-rate-ratio (IRR) = 0.25, p < 0.001, CI 0.18-0.33]. Factors influencing ARR rate while on DMF were relapsing remitting (RR) MS course (IRR = 2.0, p = <0.001, CI 1.51-2.73) and previous DMTs status: de-escalating from second-line therapies was associated to higher risk of relapsing (IRR = 1.8, p < 0.001, CI 1.39-2.31). At multivariable Cox proportional hazard model, only age of onset was related with rate or relapses, with younger age being protective (HR 0.96, p = 0,02). EDSS remained stable in 88% of patients. Disease duration was associated with higher rate of NEDA-3 failure, that was instead maintained in 65% of patients at 24 months. 109 patients (22%) discontinued therapy after a mean of 1.1 ±+ 0.7 years. Reasons for DMF discontinuation over time were lack of efficacy (50%), safety issues (30%), tolerability (7%), poor compliance (7%), and pregnancy (4%). Higher pre-treatment EDSS was associated with DMF discontinuation (p = 0.009). Only 33 patients dropped out due to safety reasons (7%), the most frequent safety issues driving to drop out being lymphopenia, liver/pancreatic enzymes increase, gatrointestinal severe tolerability issues. We recorded 95 cases (24%) of lymphopenia: 60 grade I (13%), 31 grade II (7%) and 4 grade III (1%). CONCLUSIONS: We confirm that DMF shows a good efficacy in both naïve patients and patients switching from other first-line DMTs, especially in patients with early onset of disease. Higher baseline EDSS was a risk factor for discontinuing DMF therapy, while shorter disease duration was protective for both EDSS progression and NEDA-3 status maintenance.

BACKGROUND: Both cognition and olfaction are impaired in multiple sclerosis (MS). However, little is known about the relationship between smell identification ability and measures of cognitive function in this disease. OBJECTIVE: To assess olfactory function in MS and to evaluate its relationship with cognitive and physical disability. METHODS: Fifty-five MS patients and 20 healthy controls (HCs) were tested. The University of Pennsylvania smell identification test (UPSIT) was administered to assess olfactory function. Cognitive function was tested using the symbol digit modalities test (SDMT), California verbal learning test-II (CVLT II), brief visuospatial memory test (BVMT), paced auditory serial addition test (PASAT), and controlled oral word association test (COWAT). Fatigue and depressive symptoms were evaluated using the Modified Fatigue Impact Scale and the Beck Depression Inventory II, respectively. RESULTS: MS patients had lower UPSIT scores than those of the HCs (28.76⯱â¯5.48â¯vs 31.7⯱â¯2.18, pâ¯=â¯0.02), with secondary-progressive and cognitively impaired MS patients showing the greatest impairment. Scores on the SDMT, CVLTII, BVMT and COWAT were related to the olfactory test scores. CONCLUSION: We confirm that olfactory function is impaired in MS, particularly in progressive phenotypes, and show, for the first time, that such dysfunction is related to a broad range of cognitive measures. Our data suggest that olfactory dysfunction might be considered as an indirect measure of MS severity. Longitudinal studies are needed to confirm this possibility.

BACKGROUND AND PURPOSE: Vascular pathology is increasingly acknowledged as a risk factor for multiple sclerosis (MS). Vascular density (VD) is reduced in the eyes of patients with MS on optical coherence tomography (OCT) angiography. We performed a 1-year prospective study to estimate VD variations over time and possible clinical correlates. METHODS: A total of 50 patients with MS underwent spectral domain-OCT and OCT angiography at baseline and after 1-year follow-up. Mixed-effect linear regression models were used to assess variations of each OCT measure and its relation to treatment and clinical outcomes. RESULTS: We observed an increase in parafovea VD (coefficient, 1.147; 95% confidence interval, 0.081-2.214; P = 0.035). Reduction in parafovea VD was associated with increase in Expanded Disability Status Scale score (coefficient, -0.969; 95% confidence interval, -1.732/-0.207; P = 0.013). CONCLUSIONS: Retinal VD can improve over time in MS, particularly in patients experiencing disease stability. Longer follow-up, inclusion of early MS cases and combination with conventional markers of MS severity (i.e. brain atrophy) are needed to better define VD as a potential new biomarker.

BACKGROUND: Over the last few decades, patients have increasingly been searching for health information on the Internet. This aspect of information seeking is important, especially for people affected by chronic pathologies and require lifelong treatment and management. These people are usually very well informed about the disease but are nonetheless vulnerable to hopes of being cured or saved, often amplified by misinformation, myths, legends, and therapies that are not always scientifically proven. Many studies suggest that some individuals prefer to rely on the Internet as their main source of information, often hindering the patient-doctor relationship. A professional approach is imperative to maintain confidentiality, honesty, and trust in the medical profession. OBJECTIVE: we aimed to examine, in a medically supervised Italian web community (SMsocialnetwotk.com) dedicated to people with Multiple Sclerosis (pwMS), the posts shared by users and to verify the reliability of contents of posts shared by users pinpointed as Influencers through an online questionnaire. METHODS: we grouped the posts published on SMsocialnetwork from April to June 2015 into those with medical content (scientifically correct or fake news), and those related to social interactions. Later, we gave a questionnaire to the community asking to identify the three users/Influencers providing the most reliable advice for everyday life with MS and the three users/Influencers providing the most useful information about MS treatments. RESULTS: 308 posts reported scientific and relevant medical information, whereas 72 posts included pieces of fake news. 1420 posts were of general interest. Four out of the 6 Influencers had written only posts with correct medical information (3 were pwMS, 1 was a Neurologist) and never any fake news. The remaining 2 appointed Influencers (2 pwMS) had written only posts about general interests. CONCLUSION: the identification of fake news and their authors has shown that the latter are never appointed as Influencers. SMsocialnetwork.com acted as a "web safe environment" where the Influencers contributed by sharing only correct medical information and never fake news. We speculate that the presence of neurologists and psychologists supervising the information flow might have contributed to reduce the risk of fake news spreading and to avoid their acquisition of authoritative meaning.

BACKGROUND: Wikipedia is a frequently-accessed online source of health-related information. In this study we evaluated the number of views of the Italian Wikipedia articles related to multiple sclerosis (MS) and its treatment. METHODS: Using Pageviews Analysis we assessed the total views, and mean monthly and daily views of the Italian Wikipedia articles on MS and its treatments from 1 January 2015 to 31 October 2017. We compared the views of the article on MS with those for Alzheimer´s disease, epilepsy, migraine and stroke, and adjusted results for crude disease prevalence. RESULTS: The total views of the Italian Wikipedia article on MS was 929,983 (mean monthly views: 33,214; mean daily views: 1089). The adjusted views for the Italian Wikipedia article on MS were higher than those for the other neurological disorders. The normalized views for the MS article were 16, 7, 145 and 11 times higher than those of the articles on Alzheimer's disease, epilepsy, migraine and stroke, respectively. Peaks were temporally related to famous people with MS talking about their disease in talk shows on television or to news on novel treatments for MS. CONCLUSION: Wikipedia searches do not reliably reflect its actual epidemiology. Celebrities with MS acting as testimonials might effectively increase public knowledge on MS.

OBJECTIVES: Disease-modifying treatments (DMTs) constitute the largest direct medical cost for multiple sclerosis (MS). This study aims at investigating predictors of the 10-year economic burden for DMT administration and management. MATERIALS AND METHODS: This study included 537 newly diagnosed, drug naïve relapsing-remitting MS (RRMS) patients, followed up for 10.1±3.3 years. Costs for DMT administration and management were calculated, and referred to each year of observation (annual costs). Possible predictors of disease evolution were categorized into early predictors (age, gender, disease duration, baseline expanded disability status scale (EDSS), 1-point EDSS progression within 2 years, and annualized relapse rate -ARR- within 2 years), and long-term predictors (reaching of EDSS 4.0, conversion to secondary progressive -SP-, ARR, number of DMTs, follow-up duration). Association between predictors and study outcome was explored using mixed-effects log-linear regression models. RESULTS: A 1-point higher EDSS at diagnosis was associated with 13.21% increase in the annual costs (95%CI=4.16-23.04%). Each additional year of age at diagnosis was associated with a 0.74% decrease in the annual costs (95%CI=-1.43 to-0.04%). Female gender was associated with a 12.43% decrease in the annual costs (95%CI=-22.61 to-0.93%). Converting to SP was associated with a 14.26% decrease in the annual costs (95%CI=-14.26 to-2.94%). Each additional year of follow-up was associated with a 3.05% decrease in the annual costs (95%CI=-4.51 to-1.57%). CONCLUSIONS: An estimate of the 10-year costs associated with DMT administration and management can be calculated by analyzing different factors, and might be of particular interest for planning resources needed for treating people with MS.

BACKGROUND AND PURPOSE: Growth hormone (GH)/insulin-like growth factor 1 (IGF-1) axis abnormalities in multiple sclerosis (MS) suggest their role in its pathogenesis. Interferon ß (IFN-ß) efficacy could be mediated also by an increase of IGF-1 levels. A 2-year longitudinal study was performed to estimate the prevalence of GH and/or IGF-1 deficiency in clinically isolated syndrome (CIS) patients and their correlation with conversion to MS in IFN treated patients. METHODS: Clinical and demographic features of CIS patients were collected before the start of IFN-ß-1b. IGF-1 levels and GH response after arginine and GH releasing hormone + arginine stimulation tests were assessed. Clinical and magnetic resonance imaging evaluations were performed at baseline, 1 year and 2 years. RESULTS: Thirty CIS patients (24 female) were enrolled. At baseline, four patients (13%) showed a hypothalamic GH deficiency (GHD), whilst no one had a pituitary GHD. Baseline demographic, clinical and radiological data were not related to GHD, whilst IGF-1 levels were inversely related to age (P < 0.001) and GH levels (P = 0.03). GH and IGF-1 serum mean levels were not significantly modified after 1 and 2 years of treatment in the whole group, although 3/4 GHD patients experienced a normalization of GH levels, whilst one dropped out. After 2 years of treatment 13/28 (46%) patients converted to MS. The presence of GHD and GH and IGF-1 levels were not predictive of relapses, new T2 lesions or conversion occurrence. CONCLUSIONS: Growth hormone/IGF-1 axis function was found to be frequently altered in CIS patients, but this was not related to MS conversion. Patients experienced an improvement of GHD during IFN therapy. Longer follow-up is necessary to assess its impact on disease progression.

BACKGROUND: Different retrospective studies compared natalizumab and fingolimod in relapsing-remitting multiple sclerosis (RRMS), with conflicting results. We aimed to explore the prescriptive attitude and the clinical outcome of the two therapies. METHODS: We retrospectively included all RRMS patients treated with natalizumab (n=101) or fingolimod (n=78) as their first second-line therapy with at least 24-month follow-up. Demographic and clinical features were recorded to calculate the propensity score (PS). Outcomes of interest were annualized relapse rate (ARR), risk of relapse, and change in the EDSS RESULTS: At baseline, natalizumab patients were younger and had a shorter disease duration, a higher number of relapse in 1 year (1yR) and 2 years (2yR) and overall (ARR-PT) pretherapy, compared to fingolimod patients. On therapy, the proportion of relapsing patients and the mean RR were similar in the two groups. However, the change in the ARR was higher in natalizumab than in fingolimod group (P<.002), but, using PS as a covariate, it was comparable (P=.960). Similarly, the change in EDSS was significantly different for the two groups (P<.004), but not after adjusting for the PS (P=.321). CONCLUSION: We observed a comparable efficacy on ARR reduction and on EDSS progression with natalizumab and fingolimod correcting through PS, suggesting that the efficacy difference observed before correction might derive from the clinical attitude in prescribing natalizumab in more active MS patients in real life.

BACKGROUND AND PURPOSE: Grey matter (GM) and white matter (WM) are both affected in multiple sclerosis (MS). WM is predominantly involved in inflammatory demyelination of relapsing-remitting MS (RRMS), whereas GM is predominantly involved in neurodegenerative processes of secondary progressive MS. Thus, we investigated the ratio between GM and WM volumes in predicting MS evolution. METHODS: The present 10-year retrospective cohort study included 149 patients with newly-diagnosed RRMS, undergoing magnetic resonance imaging for segmentation and brain volumetry. The ratio between GM and normal-appearing WM (NAWM) volumes was calculated for each subject. Outcome measures of interest were Expanded Disability Status Scale (EDSS) progression, reaching EDSS 4.0 and conversion to secondary progressive (SP) MS. RESULTS: During a period of 10.6 ± 2.4 years, a median 1.5 EDSS progression was observed (range 0-5.5), 54 subjects (36.2%) reached EDSS 4.0 and 30 subjects (20.1%) converted to SP. With ordinal logistic regression models, EDSS progression was associated with GM:NAWM ratio (coefficient, -2.918; 95% CI, -4.739-1.097). With Cox regression models, subjects with higher GM:NAWM ratio at diagnosis had a 90% lower rate of reaching EDSS 4.0 (hazard ratio, 0.111; 95% CI, 0.020-0.609) and of converting to secondary progressive MS (hazard ratio, 0.017; 95% CI, 0.001-0.203) compared with subjects with lower GM:NAWM ratio. CONCLUSIONS: The GM:NAWM ratio is a predictor of disability progression and of SP conversion in subjects with newly diagnosed RRMS, suggesting that GM and NAWM are variably affected in relation to disease evolution from the early phases of MS.

BACKGROUND AND PURPOSE: Very little is known about the progression of non-motor symptoms (NMSs) in Parkinson's disease (PD) and there are no longitudinal studies exploring this topic from the earliest stage, when patients receive the diagnosis. We here report on the progression of NMSs over 4 years from diagnosis in a cohort of de-novo, previously untreated, patients with PD. METHODS: Consecutive de-novo (disease duration < 2 years), untreated patients with PD were enrolled in this observational study. Evaluations were then scheduled every 2 years and included assessment of motor and non-motor features as well as of quality of life measures. RESULTS: Sixty-one patients were prospectively followed-up for 4 years from diagnosis. The majority of NMSs increased over time and significantly affected quality of life, whereas motor disability did not. There was no significant association between NMSs and dopaminergic therapy in terms of both drug class and total levodopa-equivalent daily dosage. Excessive daytime sleepiness was the only NMS correlating with therapy with dopamine agonists. Female patients were more likely to have worse quality of life. CONCLUSIONS: Non-motor symptoms significantly increase over time, with a different progression rate for each one. NMSs significantly affect quality of life in PD and we here demonstrated that this was especially the case when patients were in their (motor) honeymoon period. Future trials should target non-dopaminergic networks and consider NMSs in their outcomes.

BACKGROUND AND PURPOSE: Cardiovascular risk factors can increase the risk of multiple sclerosis (MS) and modify its course. However, such factors possibly interact, determining a global cardiovascular risk. Our aim was to compare the global cardiovascular risk of subjects with and without MS with the simplified 10-year Framingham General Cardiovascular Disease Risk Score (FR) and to evaluate its importance on MS-related outcomes. METHODS: Age, gender, smoking status, body mass index, systolic blood pressure, type II diabetes and use of antihypertensive medications were recorded in subjects with and without MS to estimate the FR, an individualized percentage risk score estimating the 10-year likelihood of cardiovascular events. RESULTS: In total, 265 MS subjects were identified with 530 matched controls. A t test showed similar FR in cases and controls (P = 0.212). Secondary progressive MS presented significantly higher FR compared to relapsing-remitting MS (P < 0.001). Linear regression analysis showed a direct relationship between FR and Expanded Disability Status Scale (P < 0.001) and MS Severity Scale (P < 0.001). CONCLUSION: The FR, evaluating the global cardiovascular health by the interaction amongst different risk factors, relates to MS disability, severity and course.

BACKGROUND AND PURPOSE: Oxidative stress is a central pathogenic mechanism of Parkinson's disease (PD), and the heme oxygenase (HO) bilirubin pathway is one of the main mammalian antioxidative defences. Indeed, there is growing evidence of HO-bilirubin upregulation from early phases of PD. Our aim was to investigate bilirubin as a possible biomarker of PD diagnosis and progression. METHODS: A cross-sectional case-control study was performed to evaluate differences in bilirubin levels between newly diagnosed, drug-naïve PD subjects and controls. Afterwards, PD subjects were included in a 2-year longitudinal study to evaluate disease progression in relation to baseline bilirubin levels. RESULTS: Seventy-five de novo PD subjects were selected and matched with 75 controls by propensity score. Analysis of variance showed higher bilirubin levels in PD patients compared with controls (P < 0.001). Linear regression analysis failed to show a relationship between bilirubin and Unified Parkinson's Disease Rating Scale (UPDRS) part III (P = 0.283) at baseline evaluation. At 2-year follow-up, indirect relationships between bilirubin levels and UPDRS part III (P = 0.028) and between bilirubin levels and levodopa-equivalent daily dosage (P = 0.012) were found. CONCLUSIONS: Parkinson's disease subjects showed higher levels of bilirubin compared with controls. Bilirubin increase might be due to HO overexpression as a compensatory response to oxidative stress occurring from early stages of PD.
