RESUMEN
BACKGROUND: Cross-sectional plasma citrulline concentration (CIT) is considered a marker of enterocyte mass. The role of CIT in clinical practice in patients with short bowel syndrome (SBS) is not clearly defined. AIM: To assess the accuracy of CIT to discriminate SBS from healthy controls (HC) and SBS with intestinal failure (SBS-IF), requiring intravenous supplementation (IVS), from SBS with intestinal insufficiency (SBS-II). METHODS: Cross-sectional study on unselected outpatients (31 SBS-II, 113 SBS-IF) and 19 healthy controls (HC). Demographic data, SBS characteristics, nutritional status, oral intake, intestinal fat absorption, renal function and IF severity, categorized by the volume of the required IVS, were collected at time of CIT evaluation (µmol/L). Data as mean±SD. RESULTS: CIT was 36.6 ± 6.0 in HC, 30.2 ± 14.0 in SBS-II and 18.8 ± 12.3 in SBS-IF (p < 0.001). CIT cutoff was 31 for the diagnosis of SBS (sensitivity 79 %, specificity 89 %), and 14 for the discrimination between SBS-IF and SBS-II (sensitivity 100 %, specificity 51 %). Wide ranges of CIT were observed in all SBS-IF severity categories. CONCLUSIONS: In unselected SBS patients, CIT was accurate to diagnose SBS, had high sensitivity to diagnose SBS-IF but showed low specificity for SBS-II. In SBS-IF, CIT was not an accurate marker of IF severity.
RESUMEN
RATIONALE: To investigate the association between malnutrition and patient outcome following hospitalisation for Corona Virus Disease 2019 (COVID-19). METHODS: In April 2020, 268 adult patients (235 included in the follow-up) hospitalised for COVID-19 infection were evaluated for malnutrition risk and diagnosis using modified Nutritional Risk Screening 2002 and modified Global Leadership Initiative on Malnutrition criteria (GLIM), respectively. An 18-month follow-up was carried out to assess the incidence and the associated risk factors for death and re-hospitalization. RESULTS: The outcome was unknown for 33 patients. Death occurred in 39% of the 235 patients included in the follow-up. The risk of death was independently associated with malnutrition risk or diagnosis of malnutrition, whereas the male sex showed a protective association. The Kaplan-Meier survival curves showed that patients with diagnosis of malnutrition had lower survival rate. The re-hospitalization rate was 31% and was negatively associated with BMI≥25, and positively associated with length of hospitalisation for COVID-19 and with cancer comorbidity. CONCLUSIONS: In hospitalized patients for SARS-CoV-2 disease, both malnutrition risk (p = 0.050) and diagnosis of malnutrition (p = 0.047 with modified GLIM and C-reactive protein >0.5 mg/dL; p = 0.024 with modified GLIM and C-reactive protein >5 mg/dL) were predictive risk factors for mortality, whereas male sex was associated with lower risk of death. Overweight at time of hospitalization and the length of hospitalisation were respectively protective and risk factor for re-hospitalization after discharge.
RESUMEN
Lifestyle factors, such as diet and sleep quality, are receiving increasing interest as accessible therapeutic approaches to migraine. The Mediterranean diet (MD) has shown clear benefits in cardiovascular and metabolic diseases, as well as in sleep patterns. Here, our objective was to identify the impact of adherence to the MD and other lifestyle factors on the clinical burden of migraine. For this purpose, we enrolled 170 migraine patients and 100 controls, assessing the clinical disability of headache using standardized clinical scales (HIT-6 and MIDAS) in the migraineur cohort and lifestyle patterns in both groups through the PREDIMED score for MD adherence, the IPAQ scale for physical activity, and BMI. Subjects were also screened for sleep-wake disturbances based on the Pittsburgh Sleep Quality Index (PSQI). We found that migraine patients had lower adherence to the MD compared to the controls and that the HIT-6 scale had a significant negative relationship with MD adherence in patients with high-frequency episodic and chronic migraine. Additionally, in the same migraine patients, the presence of sleep-wake disturbances was correlated with greater migraine disability as assessed by the MIDAS score. In conclusion, this study found that among different lifestyle factors, poor adherence to the MD and the presence of sleep-wake disturbances were closely associated with migraine disability and chronification.

OBJECTIVE: In this pilot prospective cohort study, we aimed to evaluate, using high-density electroencephalography (HD-EEG), the longitudinal changes in functional connectivity (FC) in patients with chronic migraine (CM) treated with onabotulinumtoxinA (OBTA). BACKGROUND: OBTA is a treatment for CM. Several studies have shown the modulatory action of OBTA on the central nervous system; however, research on migraine is limited. METHODS: This study was conducted at the Neurology Unit of "Policlinico Tor Vergata," Rome, Italy, and included 12 adult patients with CM treated with OBTA and 15 healthy controls (HC). Patients underwent clinical scales at enrollment (T0) and 3 months (T1) from the start of treatment. HD-EEG was recorded using a 64-channel system in patients with CM at T0 and T1. A source reconstruction method was used to identify brain activity. FC in δ-θ-α-ß-low-γ bands was analyzed using the weighted phase-lag index. FC changes between HCs and CM at T0 and T1 were assessed using cross-validation methods to estimate the results' reliability. RESULTS: Compared to HCs at T0, patients with CM showed hyperconnected networks in δ (p = 0.046, area under the receiver operating characteristic curve [AUC: 0.76-0.98], Cohen's κ [0.65-0.93]) and ß (p = 0.031, AUC [0.68-0.95], Cohen's κ [0.51-0.84]), mainly involving orbitofrontal, occipital, temporal pole and orbitofrontal, superior temporal, occipital, cingulate areas, and hypoconnected networks in α band (p = 0.029, AUC [0.80-0.99], Cohen's κ [0.42-0.77]), predominantly involving cingulate, temporal pole, and precuneus. Patients with CM at T1, compared to T0, showed hypoconnected networks in δ band (p = 0.032, AUC [0.73-0.99], Cohen's κ [0.53-0.90]) and hyperconnected networks in α band (p = 0.048, AUC [0.58-0.93], Cohen's κ [0.37-0.78]), involving the sensorimotor, orbitofrontal, cingulate, and temporal cortex. CONCLUSION: These preliminary results showed that patients with CM presented disrupted EEG-FC compared to controls restored by a single session of OBTA treatment, suggesting a primary central modulatory action of OBTA.

The biological substrate of persistent post-COVID-19 hyposmia is still unclear. However, as many neurodegenerative diseases present with smell impairment at onset, it may theoretically reflect degeneration within the central olfactory circuits. However, no data still exist regarding the post-COVID-19 patients. As the olfactory neurons (ONs) mirror pathological changes in the brain, allowing for tracking the underlying molecular events, here, we performed a broad analysis of ONs from patients with persistent post-COVID-19 OD to identify traces of potential neurodegeneration. ONs were collected through the non-invasive brushing of the olfactory mucosa from ten patients with persistent post-COVID-19 hyposmia (lasting > 6 months after infection) and ten age/sex-matched controls. Immunofluorescence staining for protein quantification and RT-PCR for gene expression levels were combined to measure ONs markers of α-synuclein, amyloid-ß, and tau pathology, axonal injury, and mitochondrial network. Patients and controls had similar ONs levels of oligomeric α-synuclein, amyloid-ß peptide, tau protein, neurofilament light chain (NfL), cytochrome C oxidase subunit 3 (COX3), and the heat shock protein 60 (HSP60). Our findings thus did not provide evidence for synucleinopathy and amyloid-ß mismetabolism or gross traces of neuronal injury and mitochondrial dysfunction within the olfactory system in the early phase of persistent post-COVID-19 hyposmia.
RESUMEN
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common monogenic form of cerebral small vessel disease, caused by a mutation in the NOTCH3 gene on chromosome 19. The main clinical features include migraine (often with aura), early onset, recurrent subcortical ischemic strokes, mood disturbances, and cognitive impairment, frequently leading to dementia and disability with a reduction in life expectancy. Cerebral chronic global hypoperfusion, due to impaired cerebrovascular reactivity, seems to play a primary role in CADASIL. Migraine is the most common early feature of the disease, and to date, there are no consensus guidelines for treatment. Given the vasomodulatory influence of many antimigraine drugs, there is concern about their use in this disease. In particular, the calcitonin gene-related peptide (CGRP) system serves as a vasodilatory protective mechanism during cerebral and cardiac ischemia. Blocking this system could exacerbate ischemic events. Herein, we describe two CADASIL patients who were treated with the calcitonin gene-related peptide (CGRP) receptor antagonist erenumab for chronic migraine, reporting a significant reduction in the frequency of attacks and intensity of pain, and an improvement in quality of life without adverse effects.
RESUMEN
BACKGROUND: Endometriosis and migraine frequently coexist, but only a limited number of studies have focused on their mutual association. The aim of our study was to investigate, in untreated women with comorbid endometriosis/adenomyosis and migraine, the correlation between headache features and endometriotic subtypes and their possible relationship with pain severity and disease disability. METHODS: Fifty women affected by endometriosis/adenomyosis and migraine matched (1:2) with 100 patients with endometriosis alone and 100 patients with only migraine were recruited and underwent pelvic ultrasound imaging and neurological examination. RESULTS: Severe adenomyosis, posterior and anterior deep infiltrating endometriosis (p = 0.027, p = 0.0031 and p = 0.029, respectively) occurred more frequently in women with migraine. Dysmenorrhea was the most commonly reported symptom in women with endometriosis and migraine and the mean VAS scores of all typical endometriotic symptoms were significantly higher in the presence of comorbidity. Women with both migraine and endometriosis reported significant higher pain intensity (p = 0.004), higher monthly migraine days (p = 0.042) and increased HIT 6-scores (p = 0.01), compared with those without endometriosis. CONCLUSIONS: Our results demonstrated that the co-occurrence of migraine in untreated women with endometriosis is associated with more severe gynecological infiltrations and correlated with increased pain intensity and disease disability.Trial Registration: Protocol number 119/21.

In the world, migraine is one of the most common causes of disability in adults. To date, there is no a single cause for this disorder, but rather a set of physio-pathogenic triggers in combination with a genetic predisposition. Among the factors related to migraine onset, a crucial role seems to be played by gut dysbiosis. In fact, it has been demonstrated how the intestine is able to modulate the central nervous system activities, through the gut-brain axis, and how gut dysbiosis can influence neurological pathologies, including migraine attacks. In this context, in addition to conventional pharmacological treatments for migraine, attention has been paid to an adjuvant therapeutic strategy based on different nutritional approaches and lifestyle changes able to positively modulate the gut microbiota composition. In fact, the restoration of the balance between the different gut bacterial species, the reconstruction of the gut barrier integrity, and the control of the release of gut-derived inflammatory neuropeptides, obtained through specific nutritional patterns and lifestyle changes, represent a possible beneficial additive therapy for many migraine subtypes. Herein, this review explores the bi-directional correlation between migraine and the main chronic non-communicable diseases, such as diabetes mellitus, arterial hypertension, obesity, cancer, and chronic kidney diseases, whose link is represented by gut dysbiosis.

BACKGROUND: The outcome of migraine patients retreated with monoclonal antibodies (mAbs) targeting the calcitonin gene-related peptide (anti-CGRP) or its receptor (anti-CGRPr) is not completely known. METHODS: This multicentric prospective observational cohort study assessed monthly migraine days (MMDs), migraine acute medication intake (MAMI), and HIT-6 at baseline, after 90-112 days (Rev-1), after 84-90 days since Rev-1 (Rev-2) and 30 days after the last injection of anti-CGRP/CGRPr mAbs (Year-end), in the first and the second year after a discontinuation period. RESULTS: We enrolled 226 patients (79.6% with chronic migraine; 55.3% on erenumab and 44.7% on galcanezumab or fremanezumab). MMDs, MAMI, and HIT-6-did not differ at the respective first and second-year evaluations in the entire cohort, and comparing anti-CGRP with anti-CGRPr Abs. MMDs (18.1 ± 7.8 vs. 3.4 ± 7.8), MAMI (26.7 ± 28.3 vs.17.7 ± 17.2), and HIT-6 scores (63.1 ± 5.9 vs. 67.1 ± 10.3) were lower in the second year than in the pre-treatment baseline (consistently, p < 0.0001). Second-year baseline MMDs were lower in patients on anti-CGRP mAbs (p = 0.001) and with lower pre-treatment baseline MMDs (p ≤ 0.001). CONCLUSION: Anti-CGRP/CGRPr mAbs are effective in the second as in the first year. The use of anti-CGRP or CGRPr mAbs influenced the second-year baseline MMDs, but their effectiveness did not differ during the two treatment years.
RESUMEN
BACKGROUND: The Cluster Headache Impact Questionnaire (CHIQ) is a specific and easy-to-use questionnaire to assess the current impact of cluster headache (CH). The aim of this study was to validate the Italian version of the CHIQ. METHODS: We included patients diagnosed with episodic CH (eCH) or chronic CH (cCH) according to the ICHD-3 criteria and included in the "Italian Headache Registry" (RICe). The questionnaire was administered to patients through an electronic form in two sessions: at first visit for validation, and after 7 days for test-retest reliability. For internal consistency, Cronbach's alpha was calculated. Convergent validity of the CHIQ with CH features and the results of questionnaires assessing anxiety, depression, stress, and quality of life was evaluated using Spearman's correlation coefficient. RESULTS: We included 181 patients subdivided in 96 patients with active eCH, 14 with cCH, and 71 with eCH in remission. The 110 patients with either active eCH or cCH were included in the validation cohort; only 24 patients with CH were characterized by a stable attack frequency after 7 days, and were included in the test-retest cohort. Internal consistency of the CHIQ was good with a Cronbach alpha value of 0.891. The CHIQ score showed a significant positive correlation with anxiety, depression, and stress scores, while showing a significant negative correlation with quality-of-life scale scores. CONCLUSION: Our data show the validity of the Italian version of the CHIQ, which represents a suitable tool for evaluating the social and psychological impact of CH in clinical practice and research.

Persistent olfactory dysfunction (OD) is one of the most complaining and worrying complications of long COVID-19 because of the potential long-term neurological consequences. While causes of OD in the acute phases of the SARS-CoV-2 infection have been figured out, reasons for persistent OD are still unclear. Here we investigated the activity of two inflammatory pathways tightly linked with olfaction pathophysiology, namely Substance P (SP) and Prokineticin-2 (PK2), directly within the olfactory neurons (ONs) of patients to understand mechanisms of persistent post-COVID-19 OD. ONs were collected by non-invasive brushing from ten patients with persistent post-COVID-19 OD and ten healthy controls. Gene expression levels of SP, Neurokinin receptor 1, Interleukin-1ß (IL-1ß), PK2, PK2 receptors type 1 and 2, and Prokineticin-2-long peptide were measured in ONs by Real Time-PCR in both the groups, and correlated with residual olfaction. Immunofluorescence staining was also performed to quantify SP and PK2 proteins. OD patients, compared to controls, exhibited increased levels of both SP and PK2 in ONs, the latter proportional to residual olfaction. This work provided unprecedented, preliminary evidence that both SP and PK2 pathways may have a role in persistent post-COVID-19 OD. Namely, if the sustained activation of SP, lasting months after infection's resolution, might foster chronic inflammation and contribute to hyposmia, the PK2 expression could instead support the smell recovery.

BACKGROUND AND PURPOSE: To evaluate the 1-year effectiveness and tolerability of galcanezumab in real life and the prognostic indicators of persistent response. METHODS: High-frequency episodic migraine (HFEM) and chronic migraine (CM) patients treated with galcanezumab who completed a 1-year observation were enrolled. The primary outcomes assessed during the 12 months (V1-V12) were the change in monthly migraine days (MMDs) from baseline and the response rates ≥50% in MMDs (MMD ≥50% RR). The secondary outcomes were changes in pain intensity (numerical rating scale [NRS]) and in monthly acute medication intake (MAMI). RESULTS: We enrolled 191 patients (77.5% CM). Twenty-three patients (12%) dropped out, two for nonserious adverse events. At least 40% of patients took add-on standard preventives from baseline to V12. At V12, MMDs were reduced by 6.0 days in HFEM and by 11.9 days in CM patients (both p < 0.00001); NRS and MAMI were also decreased in both groups (p < 0.00001). One-hundred eight (56.5%) patients presented MMD ≥50% RR for 9 cumulative months (interquartile range=8): we defined this value as the cutoff for a persistent response. Persistent responders were less likely to have a higher body mass index (BMI) (p = 0.007) but more frequently had a good response to triptans (p = 0.005) and MMD ≥50% RR at V1 (p < 0.0000001). Patients without a persistent response were on add-on therapy for longer periods of time (p < 0.001). CONCLUSIONS: Galcanezumab was effective and well-tolerated in the 1-year term, with most patients presenting MMD ≥50% RR for at least 9 months. Triptan response, lower BMI, and MMD ≥50% RR in the first month emerged as predictive factors for a persistent response.

BACKGROUND AND OBJECTIVES: The identification of predictors of response to antiCGRP mAbs could favor tailored therapies and personalized treatment plans. This study is aimed at investigating predictors of ≥ 50%, ≥ 75% and 100% response at 24 weeks in patients with high-frequency episodic (HFEM: 8-14 days/month) or chronic migraine (CM). METHODS: This is a large, multicenter, cohort, real-life study. We considered all consecutive adult patients affected by HFEM or CM who were prescribed antiCGRP mAbs for ≥ 24 weeks in 20 headache centers. Patients were interviewed face-to-face using a shared semi-structured questionnaire carefully exploring socio-demographic and clinical characteristics. Patients received subcutaneous erenumab (70 mg or140 mg, monthly), galcanezumab (120 mg monthly, following a 240 mg loading dose), or fremanezumab (225 mg, monthly or 675 mg, quarterly) according to drug market availability, physician's choice, or patient's preference. The primary endpoint of the study was the assessment of ≥ 50% response predictors at 24 weeks. Secondary endpoints included ≥ 75% and 100% response predictors at 24 weeks. RESULTS: Eight hundred sixty-four migraine patients had been treated with antiCGRP mAbs for ≥ 24 weeks (erenumab: 639 pts; galcanezumab: 173 pts; fremanezumab: 55 pts). The ≥50% response (primary endpoint) in HFEM was positively associated with unilateral pain (UP) + unilateral cranial autonomic symptoms (UAs) (OR:4.23, 95%CI:1.57-11.4; p = 0.004), while in CM was positively associated with UAs (OR:1.49, 95%CI:1.05-2.11; p = 0.026), UP + UAs (OR:1.90, 95%CI:1.15-3.16; p = 0.012), UP + allodynia (OR:1.71, 95%CI:1.04-2.83; p = 0.034), and negatively associated with obesity (OR:0.21, 95%CI:0.07-0.64; p = 0.006). The 75% response (secondary endpoint) was positively associated with UP + UAs in HFEM (OR:3.44, 95%CI:1.42-8.31; p = 0.006) and with UP + UAs (OR:1.78, 95%CI:1.14-2.80; p = 0.012) and UP + allodynia (OR:1.92, 95%CI:1.22-3.06; p = 0.005) in CM. No predictor of 100% response emerged in patients with HFEM or CM. CONCLUSIONS: A critical evaluation of headache characteristics indicating peripheral or central sensitization may help in predicting responsiveness to antiCGRP mAbs in HFEM and CM. A more precise pain profiling may represent a steppingstone for a mechanism-based approach and personalized treatment of migraine with compounds targeting specific molecular mechanisms.

RESUMEN
BACKGROUND: Olfactory dysfunction (OD)-including anosmia and hyposmia-is a common symptom of COVID-19. Previous studies have identified olfactory training (OT) as an important treatment for postinfectious OD; however, little is known about its benefits and optimizations after SARS-CoV-2 infection. OBJECTIVE: This study aimed to assess whether olfactory training performance can be optimized using more fragrances over a shorter period of time in patients with persistent OD after COVID-19. In addition, we determined the presence of other variables related to OD and treatment response in this population. METHODS: This multicenter randomized clinical trial recruited 80 patients with persistent OD and prior COVID-19 infection for less than 3 months. The patients were divided into 2 groups receiving either 4 or 8 essences over 4 weeks. Subjective assessments and the University of Pennsylvania Smell Identification Test (UPSIT) were performed before and after the treatment. RESULTS: Significant olfactory improvement was measured subjectively and using the UPSIT in both groups; however, no significant differences between the groups were observed. Additionally, the presence of olfactory fluctuations was associated with higher UPSIT scores. CONCLUSION: These data suggest that training intensification by increasing the number of essences for 4 weeks does not show superiority over the classical method. Moreover, fluctuant olfaction seems to be related to a higher score on the UPSIT.

OBJECTIVE: To investigate in real-life the conversion from chronic migraine (CM) to episodic migraine (EM), specifically to EM with High-Frequency (HFEM: 8-14 monthly migraine days, MMDs), Medium-Frequency (MFEM, 4-7 MMDs), and Low-Frequency EM (LFEM, 0-3 MMDs), and its persistence during 1 year of treatment with galcanezumab. METHODS: Consecutive CM patients treated with galcanezumab completing 1 year of observation were enrolled. We collected data on MMDs, pain intensity (Numeric Rating Scale, NRS score), and monthly acute medication intake (MAMI) from baseline (V1) to the 12-month visit (V12). RESULTS: Of the 155 enrolled patients, 116 (around 75%) reverted to EM at every visit and 81 (52.3%) for the entire 1-year treatment. Patients with older onset age (p = 0.010) and fewer baseline MMDs (p = 0.005) reverted more frequently to EM. At V12, 83 participants (53.5%) presented MFEM or LFEM. Patients reverted to MFEM or LFEM for 7 months (25th 1, 75th 11). The medication overuse discontinuation rate at V12 was 82.8% and occurred for 11 months (25th 8, 75th 12). From baseline to V12, the MAMI decreased by 17 symptomatic drugs (p < 0.000001) while the NRS score reduced by almost 2 points (p < 0.000001). A consistent transition to EM for the entire treatment year was observed in 81 (52.3%) patients. DISCUSSION: The 1-year GARLIT experience suggests that more than half of CM patients treated with galcanezumab persistently reverted to EM in real life. TRIAL REGISTRATION: ClinicalTrials.gov NCT04803513.

BACKGROUND: Fremanezumab has demonstrated to be effective, safe, and tolerated in the prevention of episodic or chronic migraine (CM) in randomized, placebo-controlled trials (RCTs). Real-life studies are needed to explore drug effects in unselected patients in routine circumstances and to provide higher generalizability results. This study explores the effectiveness, safety, and tolerability of fremanezumab in a real-life population of individuals affected by high-frequency episodic (HFEM: 8-14 days/month) or CM. METHODS: This is a 12-week multicenter, prospective, cohort, real-life study. We considered all consecutive patients affected by HFEM or CM visited at 9 Italian headache centers from 28/07/2020 to 11/11/2020. Eligible patients were given subcutaneous fremanezumab at the doses of 225 mg monthly or 675 mg quarterly, according to their preference. Primary study endpoints were the change in monthly migraine days (MMDs) in HFEM and monthly headache days (MHDs) in CM patients at weeks 9-12 compared to baseline. Secondary endpoints encompassed variation in monthly analgesic intake (MAI), Numerical Rating Scale (NRS), HIT-6 and MIDAS scores, and ≥ 50%, ≥ 75% and 100% responder rates at the same time intervals. RESULTS: Sixty-seventh number migraine patients had received ≥ 1 subcutaneous fremanezumab dose and were considered for safety analysis, while 53 patients completed 12 weeks of treatment and were included also in the effectiveness analysis. Fremanezumab was effective in both HFEM and CM, inducing at week 12 a significant reduction in MMDs (-4.6, p < 0.05), MHDs (-9.4, p < 0.001), MAI (-5.7, p < 0.05; -11.1, p < 0.001), NRS (-3.1, p < 0.001; -2.5, p < 0.001), and MIDAS scores (-58.3, p < 0.05; -43.7; p < 0.001). HIT-6 was significantly reduced only in HFEM patients (-18.1, p < 0.001). Remission from CM to episodic migraine and from MO to no-MO occurred in 75% and 67.7% of the patients. The ≥ 50%, ≥ 75% and 100% responder rates at week 12 were 76.5%, 29.4% and 9.9% in HFEM and 58.3%, 25% and 0% in CM. Younger age emerged as a positive response predictor (OR = 0.91; 95% CI 0.85-0.98, p = 0.013). Treatment-emergent adverse events were uncommon (5.7%) and mild. No patient discontinued fremanezumab for any reason. CONCLUSIONS: Fremanezumab seems more effective in real-life than in RCTs. Younger age emerges as a potential response predictor.
