Diabetic peripheral neuropathic pain is a stronger predictor of depression than other diabetic complications and comorbidities.

Aims: To investigate the independent effect on depression of painless diabetic polyneuropathy, painful diabetic polyneuropathy, and general and diabetes-related comorbidities. Methods: In 181 patients, the presence of painless diabetic polyneuropathy, painful diabetic polyneuropathy, comorbidities and depression was assessed using the Michigan Neuropathy Screening Instrument Questionnaire, the Michigan Diabetic Neuropathy Score, nerve conduction studies, the Douleur Neuropathique en 4 Questions, the Charlson Comorbidity Index and the Beck Depression Inventory-II. Results: In all, 46 patients met the criteria of confirmed painless diabetic polyneuropathy and 25 of painful diabetic polyneuropathy. Beck Depression Inventory-II scores indicative of mild-moderate-severe depression were reached in 36 patients (19.7%). In a multiple logistic regression analysis (including age, sex, body mass index, being unemployed, duration, haemoglobin A1c, insulin treatment, systolic blood pressure, nephropathy, retinopathy, Charlson Comorbidity Index and painful diabetic polyneuropathy), female sex (odds ratio: 5.9, p = 0.005) and painful diabetic polyneuropathy (odds ratio: 4.6, p = 0.038) were the only independent predictors of depression. Multiple regression analysis, including Douleur Neuropathique en 4 Questions and Michigan Diabetic Neuropathy Score instead of painful diabetic polyneuropathy, showed that Douleur Neuropathique en 4 Questions, in addition to female sex, was a significant predictor of depressive symptoms severity (p =0.005). Conclusion: Painful diabetic polyneuropathy is a greater determinant of depression than other diabetes-related complications and comorbidities. Painful symptoms enhance depression severity more than objective insensitivity

Assessment of diagnostic criteria for multifocal motor neuropathy in patients included in the Italian database

Background and purposeThis study aimed to assess the diagnostic criteria, ancillary investigations and treatment response using real-life data in multifocal motor neuropathy (MMN) patients.MethodsClinical and laboratory data were collected from 110 patients enrolled in the Italian MMN database through a structured questionnaire. Twenty-six patients were excluded due to the unavailability of nerve conduction studies or the presence of clinical signs and symptoms and electrodiagnostic abnormalities inconsistent with the MMN diagnosis. Analyses were conducted on 73 patients with a confirmed MMN diagnosis and 11 patients who did not meet the diagnostic criteria.ResultsThe European Federation of Neurological Societies/Peripheral Nerve Society (EFNS/PNS) diagnostic criteria were variably applied. AUTHOR:When applying the American Association of Electrodiagnostic Medicine criteria, an additional 17% of patients fulfilled the criteria for probable/definite diagnosis whilst a further 9.5% missed the diagnosis. In 17% of the patients only compound muscle action potential amplitude, but not area, was measured and subsequently recorded in the database by the treating physician. Additional investigations, including anti-GM1 immunoglobulin M antibodies, cerebrospinal fluid analysis, nerve ultrasound and magnetic resonance imaging, supported the diagnosis in 46%-83% of the patients. Anti-GM1 immunoglobulin M antibodies and nerve ultrasound demonstrated the highest sensitivity. Additional tests were frequently performed outside the EFNS/PNS guideline recommendations.ConclusionsThis study provides insights into the real-world diagnostic and management strategies for MMN, highlighting the challenges in applying diagnostic criteria

Impact of 2021 European Academy of Neurology/Peripheral Nerve Society diagnostic criteria on diagnosis and therapy of chronic inflammatory demyelinating polyradiculoneuropathy variants

Background and purpose: there are different criteria for the diagnosis of different variants of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). The 2021 European Academy of Neurology/Peripheral Nerve Society (EAN/PNS) guidelines provide specific clinical criteria for each CIDP variant even if their therapeutical impact has not been investigated. Methods: we applied the clinical criteria for CIDP variants of the 2021 EAN/PNS guidelines to 369 patients included in the Italian CIDP database who fulfilled the 2021 EAN/PNS electrodiagnostic criteria for CIDP. Results: according to the 2021 EAN/PNS clinical criteria, 245 patients achieved a clinical diagnosis of typical CIDP or CIDP variant (66%). We identified 106 patients with typical CIDP (29%), 62 distal CIDP (17%), 28 multifocal or focal CIDP (7%), four sensory CIDP (1%), 27 sensory-predominant CIDP (7%), 10 motor CIDP (3%), and eight motor-predominant CIDP (2%). Patients with multifocal, distal, and sensory CIDP had milder impairment and symptoms. Patients with multifocal CIDP had less frequently reduced conduction velocity and prolonged F-wave latency and had lower levels of cerebrospinal fluid protein. Patients with distal CIDP more frequently had reduced distal compound muscle action potentials. Patients with motor CIDP did not improve after steroid therapy, whereas those with motor-predominant CIDP did. None of the patients with sensory CIDP responded to steroids, whereas most of those with sensory-predominant CIDP did. Conclusions: the 2021 EAN/PNS criteria for CIDP allow a better characterization of CIDP variants, permitting their distinction from typical CIDP and more appropriate treatment for patients

Management of Spasticity in a Frail Multiple Sclerosis Patient During the COVID-19 Pandemic

Spasticity is a common symptom in patients with multiple sclerosis, and it is associated with fatigue, anxiety, depression, pain and mobility and bladder dysfunction, negatively affecting patient quality of life. During the COVID-19 pandemic, several patients were not able to continue treatment for multiple sclerosis. Here, we present a case of a 45-year-old man who experienced symptoms that worsened after discontinuing nabiximols treatment during the lockdown. Within 2 months of treatment restoration, the patient showed a strong improvement in his overall clinical condition

Anti-HBs titers are not decreased after treatment with oral Cladribine in patients with Multiple Sclerosis vaccinated against Hepatitis B virus

Background: Oral cladribine is a novel treatment for Multiple Sclerosis (MS). It is a purine nucleoside antimetabolite analogue that is incorporated into the DNA, resulting in single-strand breaks in DNA and apoptosis of replicating lymphocytes. Specifically, Cladribine induces limited depletion of CD4 and CD8 T cell subsets and more marked depletion of memory B cell subsets. Therefore, natural and acquired humoral responses against pathogens may be potentially reduced. The aim of this study was to assess longitudinal variation of antiHBs titers in patients with MS treated with Cladribine.Methods: Patients with MS treated with 1 cycle of Cladribine (3,5 mg/kg) and previously vaccinated against Hepatitis B virus (HBV) were enrolled. Anti-HBs titers were compared before and after 12 months from Cladribine treatment. Total lymphocyte count was also analysed.Results: Among the 13 RMS patients (10 F, 3 M, mean age 33,8, SD 5,9) enrolled, all had anti-HBs titers >10 mg/dl at baseline. Anti-HBs titer dropped below the reference value at 12 months after Cladribine only in 1 case. Pre-post Cladribine mean anti-HBs values were not significantly different considering the whole cohort (Wilcoxon-Mann-Whitney Test p = 0,762). Four patients had grade 1 and 1 patient grade 2 lymphocytopenia at 12 months.Conclusions: : Cladribine does not seem to reduce humoral immune responses in subjects previously vaccinated against HBV, even in case of lymphocytopenia. These results, if confirmed in larger populations, appear reassuring also for other vaccinations (i.e. COVID19). The low impact of Cladribine on plasma cells may explain such findings

Acute disseminated encephalomyelitis following Campylobacter jejuni gastroenteritis: Case report and review of the literature

We describe a case of a 25-year-old male with a diagnosis of acute disseminated encephalomyelitis (ADEM) following infection with Campylobacter jejuni, which is implicated in various human pathologies regarding the central nervous system (CNS) with acute course like Guillain-Barré syndrome (GBS), Miller-Fisher syndrome (MFS), Bickerstaff's brainstem encephalitis (BEE), acute transverse myelitis (ATM) as well as ADEM. These conditions are caused by cross-reactivity between Campylobacter's epitopes and cells of the CNS that causes an immunomediated inflammatory demyelination of the CNS. In the acute phase, magnetic resonance (MR) can detect pathologic signal intensity at the CNS with areas of pathologic contrast enhancement at cortical and spinal white matter that normalize over time or can be stable. These findings can be associated with edema in parts of the CNS. The lesions typically appear at different times during the disease course and also can have a different evolution. Our purpose therefore was to describe the clinical course and MR findings of this case and perform a critical review of the literature

COVID-19 vaccine hesitancy among Italian people with multiple sclerosis

Introduction Vaccine hesitancy promotes the spread of infectious diseases including COVID-19 virus, limiting the herd immunity. Complications caused by COVID-19 in people with multiple sclerosis forced governments to ensure them prior access to vaccinations. Their propensity to be vaccinated needs to be assessed to promote adhesion to vaccination programs. The aim of this study was to explore the COVID-19 vaccine hesitancy rate in pwMS.Methods We conducted an observational study recruiting patients affected by multiple sclerosis followed at MS Clinical and Research Unit of Tor Vergata University, Rome. We invited them to fill in an online survey about their intent to get COVID-19 vaccination. Fisher's exact test and Kruskal-Wallis test were performed to explore differences in sociodemographic, clinical, and emotional variables relative to the opinions about vaccinations. An exploratory factor analysis (EFA) was performed to assess the factorial structure of the questionnaire; Pearson's correlations between the factors and Big Five personality dimensions were also calculated.Results Of 276 respondents, 90% was willing to get vaccinated, while only 1.4% was sure to refuse the vaccination. Education level, opinions on safety and efficacy of vaccines, and emotional status were found to be associated to the propensity of getting the COVID-19 vaccination (respectively: p = 0.012, p < 0.001, and p = 0.0001). Moreover, general opinions on healthcare system were related to the intention to get vaccinated.Conclusion Our results reinforce the importance of a good relationship between doctor and patient and the need to adapt doctors' communication strategy to patients' personalities and beliefs

Adherence to social distancing and use of personal protective equipment and the risk of SARS-CoV-2 infection in a cohort of patients with multiple sclerosis

Background Aiming to safeguard its population from COVID19 infection, Italian government provided specific advices, especially to fragile individuals such those affected by Multiple Sclerosis (MS), to respect social distancing, to arrange remote work and to use personal protective equipment (PPE). The aim of this study is to investigate real adherence to these measures among MS patients and to evaluate its impact on exposure to infection. Methods MS patients followed at the MS center of Tor Vergata University hospital, Rome, Italy were asked to complete an anonymous 35-items web-survey exploring demographics, residency, employment, social distancing habits, use of PPE, MS features and COVID19 infection data, including self-reported information about contacts with SARS-CoV-2 positive/presumed positive persons. In order to estimate adherence to social distancing and use of PPE, an overall \u2018Lockdown Score\u2019 (LS) on 0\u201310 scale was created analyzing four main domains (Working (0 - 4), Social distancing and PPE use (0 - 4), Assistance for shopping needs (0 - 2), Residency (-2 - 0)). Mean scores for several pre-defined subgroups of patients were compared using both univariable and multivariable analyses. Accuracy of the score in discriminating subjects at higher risk of coming in contact with SARS-CoV-2 positive/presumed positive individuals was calculated as the area under the receiver-operator characteristic curve (AUC). The optimal cut-off was identified and used to dichotomize LS (high/ low). Logistic regression model was applied to estimate individuals' characteristics associated with high/low LS and odds ratio of coming in contact with SARS-CoV-2 positive/presumed positive persons based on continous and dichotomised LS. Results Respondents (N = 551) had a mean(\ub1SD) overall LS of 6.52\ub12.11 (Working 3.16\ub11.19, Social distancing and PPE use 2.69\ub11.33, Assistance 0.66\ub1 0.62, Residency penalty applied in 4 cases). Female, disabled and unemployed individuals had significantly higher mean LS (p<0.05). The AUC of the LS was 0.68 (95% CI, 0.59\u20130.77) and the optimal LS cut-off for discrimination was 6.0. Consistently, female, disabled and unemployed individuals had higher odd of getting a high LS ( 65 6) compared to male, independent and employed (p<0.05). Odd of coming in contact with SARS-CoV-2 positive/presumed positive individuals was significantly reduced for one-unit increase in LS (0.74 (95% CI: 0.64\u20130.85)) and among individuals with high LS (0.37 (95% CI: 0.19\u20130.72)). Only one subject among respondents declared to have been diagnosed with COVID19. Conclusions MS patients, especially those with social unfavorable conditions, demonstrated good adherence to social distancing and use of protection equipment. Implementing domains, such as social assistance, may improve protection from infection. LS score is potentially able to identify subjects with behaviors at greater risk of infection, although it needs to be validated against MS population living in higher incidence areas
