Structural brain characteristics of epilepsy patients with comorbid migraine without aura

Migraine is a common bi-directional comorbidity of epilepsy, indicating potential complex interactions between the two conditions. However, no previous studies have used brain morphology analysis to assess possible interactions between epilepsy and migraine. Voxel-based morphometry (VBM), surface-based morphometry (SBM), and structural covariance networks (SCNs) can be used to detect morphological changes with high accuracy. We recruited 30 individuals with epilepsy and comorbid migraine without aura (EM), along with 20 healthy controls (HC) and 30 epilepsy controls (EC) without migraine. We used VBM, SBM, and SCN analysis to compare differences in gray matter volume, cortical thickness, and global level and local level graph theory indexes between the EM, EC, and HC groups to investigate structural brain changes in the EM patients. VBM analysis showed that the EM group had gray matter atrophy in the right temporal pole compared with the HC group (p < 0.001, false discovery rate correction [FDR]). Furthermore, the headache duration in the EM group was negatively correlated with the gray matter volume of the right temporal pole (p < 0.05). SBM analysis showed cortical atrophy in the left insula, left posterior cingulate gyrus, left postcentral gyrus, left middle temporal gyrus, and left fusiform gyrus in the EM compared with the HC group (p < 0.001, family wise error correction). We found a positive correlation between headache frequency and the cortical thickness of the left middle temporal gyrus (p < 0.05). SCN analysis revealed no differences in global parameters between the three groups. The area under the curve (AUC) of the nodal betweenness centrality in the right postcentral gyrus was lower in the EM group compared with the HC group (p < 0.001, FDR correction), and the AUC of the nodal degree in the right fusiform gyrus was lower in the EM group compared with the EC group (p < 0.001, FDR correction). We found clear differences in brain structure in the EM patients compared with the HC group. Accordingly, migraine episodes may influence brain structure in epilepsy patients. Conversely, abnormal brain structure may be an important factor in the development of epilepsy with comorbid migraine without aura. Further studies are needed to investigate the role of brain structure in individuals with epilepsy and comorbid migraine without aura.

Ovarian Dermoid Cyst Trajectory in Premenarchal Girls

Study ObjectiveMature ovarian dermoid cysts (ODCs) are the most common benign ovarian tumors diagnosed in children. However, there is minimal data on management of ODCs in premenarchal patients. This study assesses characteristics associated with expectant (EM) vs surgical (SM) management in premenarchal patients and the growth rate of ODCs in EM patients at a single institution. MethodsForty-four premenarchal patients, either post-surgical with pathologically-confirmed ODC or having radiologic findings consistent with ODCs, were included. Data collected included demographics, cyst characteristics, imaging findings, presence of symptoms, surgical procedure performed, and ovarian torsion occurrence. ResultsPatient age at diagnosis was similar between groups (SM: 8.8 vs EM: 8.0, P = .55). At presentation, 36 patients (82%) underwent SM and 8 (18%) underwent EM. There was a significant difference in cyst size between groups (SM: 8.9 cm vs EM: 3.6 cm, P = .004). Of SM patients, 30% underwent oophorectomy vs cystectomy, with a significant difference in ODC size between procedures (11.8 cm vs 7.7 cm, P = .016). Of EM patients, 75% had at least one and 60% had three follow-up ultrasounds, with average follow-up timeframes of 3.7 and 27 months respectively. Average yearly ODC growth rate for the latter group was 0.8 cm. ConclusionThe average yearly growth rate of ODCs in premenarchal patients within our institution was slower than in older cohorts, and both age and cyst size played significant roles in determining surgical procedure. Continued study on EM in premenarchal ODCs will help define parameters for recommending SM vs EM in this population.

Cost Effectiveness of Fremanezumab in Episodic and Chronic Migraine Patients from a Japanese Healthcare Perspective.

Fremanezumab is an effective treatment for episodic (EM) and chronic migraine (CM) patients in Japan, but its cost effectiveness remains unknown. The objective of this study was to determine the cost effectiveness of fremanezumab compared with standard of care (SOC) in previously treated EM and CM patients from a Japanese healthcare perspective. Estimated regression models were implemented in a probabilistic Markov model to inform effectiveness and health-related quality-of-life data for fremanezumab and SOC. The model was further populated with data from the literature. The adjusted Japanese healthcare perspective included productivity losses. The main model outcomes were quality-adjusted life-years (QALYs), costs (2022 Japanese Yen [¥]), and incremental outcomes including the incremental cost-effectiveness ratio (ICER). Analyses were performed separately for the EM and CM patients and combined. Costs and effects were discounted at an annual rate of 2.0%. The mean QALYs over a 25-year time horizon for the EM and CM populations combined were 13.03 for SOC and 13.15 for fremanezumab. The associated costs were ¥27,550,292 for SOC and ¥28,371,048 for fremanezumab. QALYs were higher and costs lower for EM patients compared with CM patients for both fremanezumab and SOC. The deterministic ICERs of fremanezumab versus SOC were ¥6,334,861 for EM, ¥7,393,824 for CM, and ¥6,530,398 for EM and CM combined. Indirect costs and choice of mean migraine days model distribution had a substantial impact on the ICER. Using fremanezumab in a heterogeneous mixture of Japanese EM and CM patients resulted in a reduction of monthly migraine days and thus more QALYs compared with SOC. The cost effectiveness of fremanezumab versus SOC in EM and CM patients resulted in an ICER of ¥6,530,398, from an adjusted Japanese public healthcare perspective.

CGRP neuropeptide levels in patients with endometriosis-related pain treated with dienogest: a comparative study

Background and objectiveEndometriosis (EM) involves the peripheral nervous system and causes chronic pain. Sensory nerves innervating endometriotic lesions contribute to chronic pain and influence the growth phenotype by releasing neurotrophic factors and interacting with nearby immune cells. Calcitonin gene-related peptide (CGRP), a pain-signaling neurotransmitter, has a significant role. This study examines the effect of Dienogest (DNG), a hormone therapy used for managing EM -related pain, on serum CGRP levels in EM patients.Materials and methodsThe Visual Analog Scale (VAS) assessed pain in diagnosed EM. individuals. Serum samples were obtained to measure CGRP concentration. Participants received a 2 mg/day oral dose of DNG for six months as prescribed treatment. Additional serum samples were collected after this period to measure CGRP levels.ResultsIn the EM group, 6.7%, 33.3%, and 20% had ovarian EM, ovarian plus uterosacral, and ovarian plus bladder, respectively. The EM group showed higher CGRP serum levels than the control group (80.53 ± 16.13 vs. 58.55 ± 6.93, P < 0.0001). Still, after drug administration, CGRP serum levels significantly decreased compared to pre-treatment levels (69.66 ± 11.53 vs. 80.53 ± 16.13, P < 0.05). The EM group showed higher pain compared to the control group (7.93 ± 1.58 vs. 0.13 ± 0.35, P < 0.0001), but after drug administration, pain significantly decreased compared to pre-treatment levels (1.00 ± 2.00 vs. 7.93 ± 1.58, P < 0.05).ConclusionDNG administration reduces pain and serum CGRP levels in EM patients, offering the potential for innovative treatments and tailored options. Understanding neurotransmitter roles and drug effects can aid in discovering more effective modulators for these pathways.

Comparison of microbial abundance and diversity in uterine and peritoneal fluid in infertile patients with or without endometriosis

IntroductionEndometriosis (EM) is a multifactorial disease that affects 10 − 15% of women of reproductive age. Additionally, 30–50% of women with EM suffer from infertility. The mechanism of infertility caused by EM has not yet been consistently explained. In recent years, studies have shown a link between infertility associated with EM and changes in the reproductive tract microbiota.MethodsIn this study, we involved 26 EM patients (8 cases of stage I-II and 18 cases of stage III-IV) and 31 control subjects who were tubal obstruction-related infertility (TORI). The samples from peritoneal fluid (PF) and uterine fluid (UF) were collected and sequenced by 16 S rRNA amplicon.ResultsIn the comparison of microbial diversity, we found no significant differences in the microbial diversity of PF and UF between patients with stage I-II EM and those with TORI. However, there was a significant difference in microbial diversity among patients with stage III-IV EM compared to the previous two groups. Lactobacillus decreased in PF of EM compared to the control group, while it increased in UF. In PF, the abundance of Pseudomonas, Enterococcus, Dubosiella and Klebsiella was significantly higher in patients with stage III-IV compared to TORI patients. And in UF, the main differences existed between stage I-II EM compared to the other two groups. The abundance of pontibacter, aquabacterium, Rikenellaceae and so on at the genus level was significantly enriched in the EM patients with stage I-II. In the analysis based on KEGG database, EM may affect the receptivity related pathways of the endometrium by influencing changes in the uterine microbiota.ConclusionOur results indicated that as EM progresses, the microorganisms in UF and PF keep changing. These changes in the microbiota, as well as the resulting alternations in gene functional classification, may play an important role in the infertility associated with EM.

Erythema multiforme: A retrospective study of etiologies, clinical manifestations, and treatments

Background/purposeErythema multiforme (EM) is considered a hypersensitivity reaction associated with drugs and infections, and remains underestimated due to the lack of precise classification and diagnostic criteria. The aim of this study was to evaluate the triggering factors and clinical manifestations of EM and to present our experience in the diagnosis and management of this disorder. Materials and methodsAll patient records were reviewed, and records of patients admitted, diagnosed, and treated with EM were retrieved. Data on age, gender, medical history, triggering factor(s), clinical form, mucosal/cutaneous involvement, affected oral site(s), recurrence, and treatment were collected. The data were analyzed statistically at a significance level set at P < 0.05. ResultsA total of 36 EM patients were studied. The triggering factor was identified as infection in 25 %, drugs in 16.7 %, infections and drugs in 41.7 %, and none in 16.7 % of the 36 EM patients. EM minor was diagnosed in 77.8 % of the patients. Labial mucosa (86.1 %) was the most commonly affected oral site. Most patients were treated with topical steroids (25 %). No significant differences were detected between demographic and clinical characteristics with regards to gender, triggering factor, and the number of affected oral sites (P > 0.05). ConclusionThe results of this study, based on the data from 36 EM patients with oral involvement treated at our clinic, can guide dentists in this regard and may be considered as an epidemiological source for the region.

Comorbid pathology of the mammary glands and endometriosis: risk factors and prognosis

Aim: based on a retrospective analysis, the relationship between external genital endometriosis and comorbid breast pathology was established and risk factors were identified, their comparison and the formation of a prognostic risk criterion were determined. Materials and Methods: to address the objectives of the study, a retrospective analysis of 470 cases of patients treated for external genital endometriosis after surgical treatment and comorbid breast pathology was conducted. The control group included 30 healthy non-pregnant women. Statistical processing was performed on a personal computer using the statistical software package Statistica 10. Results: As a result of the analysis, the age of the patients ranged from 23 to 40 years. The average age of patients in the study group was (32.2}1.18) years, and in the control group (31.1}1.35) (p&gt;0.05). The groups were homogeneous in terms of age (p&gt;0.05), marital status (p&gt;0.05) and level of education (p&gt;0.05). Close relatives in 208 (44.25}2.18) % (OR=8.86; 95 % CI: (0.68-10.53); p&lt;0.002) cases suffered from benign (hormone-dependent) tumours and tumour-like diseases of the uterus and appendages in isolation or in various combinations (fibroids, adenomyosis, endometrial hyperplasia). It was also found that 102 (21.70}1.67) % of patients had endometriosis, which may indicate a genetic predisposition to this disease. In the closest relatives of EM patients: in 118 (25.10}2.01) % of the examined parents, breast problems were noted, in 66 (14.04}1.12) % – diabetes mellitus, and in 98 (20.85}1.22) % thyroid diseases were detected, which in total amounted to (60.00}2.23) % (OR=9.12; 95 % CI: (0.58-11.54); p&lt;0.002). Early menarche almost tripled the risk of EM (OR=2.72; 95% CI: (1.02-5.11); p&lt;0.002), and menstrual irregularities doubled it (OR=2.04; 95% CI: (1.09-3.14); p&lt;0.05), higher education, urban residents – 2.2 times higher (OR= 2.27; 95 % CI: (1.11-3.63); p&lt;0.05), diseases of the gastrointestinal tract and hepatobiliary complex – 5.2 times higher (OR=5.27; 95 % CI: (1.89-12.03); p&lt;0.05), frequently recurrent inflammatory diseases of the appendages – 3 times higher (OR=3.14; 95 % CI: (0.91-5.14); p&lt;0.05), dysmetabolic manifestations (thyroid dysfunction) – 5 times higher (OR=5.11; 95 % CI: (1.61-9.503); p&lt;0.002). Conclusions: Thus, in endometriosis and dyshormonal diseases of the mammary glands, menstrual and generative function disorders, along with clinical symptoms of pelvic pain, dysmenorrhoea, autonomic nervous system disorders and sexual dysfunction, are significant components of this problem, initiating comorbidity processes in target organs in the setting of hormonal maladaptation. Therefore, these comorbidities become a trigger for the activation of systemic hormonal imbalance and become an urgent interdisciplinary problem that requires further study.

Emergency department use of an electronic differential diagnosis generator in the evaluation of critically ill patients.

Accurate diagnosis is an essential component of managing critically ill emergency department (ED) patients. Electronic diagnosis generators (EDGs) are software tools which assist clinicians in their diagnosis generation; however, they have not been evaluated for use for critical ED patients. We aimed to evaluate the use of an EDG for this population to determine its impact on diagnosis generation and diagnostic testing. We performed an observational study on usage of an EDG in the high-acuity area of a tertiary care ED. The EDG was used by residents evaluating each patient in the area. The resident used the EDG when the case was felt to have diagnostic uncertainty and completed a data collection tool. Data were summarized by frequencies. Chi-squared or Fisher's exact tests were used to assess the association of added value of the EDG for diagnosis generation and diagnostic testing. Over the 8-month study period, the EDG was utilized to evaluate 98 critical ED patients, of whom 60% were female, 7% were pediatric, and 46% were elderly. It was used most commonly for gastroenterological, infectious disease/immunologic, metabolic/renal, and neuropsychiatric presentations, and was least used for trauma presentations. Use of the EDG led to a diagnosis not initially considered in 47% of cases and led to additional diagnostic testing in 4% of cases. EDGs have some potential to improve diagnosis in critical EM patients by expanding the differential diagnosis and, to a lesser extent, altering diagnostic testing.

Increased MRI-based Brain Age in chronic migraine patients

IntroductionNeuroimaging has revealed that migraine is linked to alterations in both the structure and function of the brain. However, the relationship of these changes with aging has not been studied in detail. Here we employ the Brain Age framework to analyze migraine, by building a machine-learning model that predicts age from neuroimaging data. We hypothesize that migraine patients will exhibit an increased Brain Age Gap (the difference between the predicted age and the chronological age) compared to healthy participants.MethodsWe trained a machine learning model to predict Brain Age from 2,771 T1-weighted magnetic resonance imaging scans of healthy subjects. The processing pipeline included the automatic segmentation of the images, the extraction of 1,479 imaging features (both morphological and intensity-based), harmonization, feature selection and training inside a 10-fold cross-validation scheme. Separate models based only on morphological and intensity features were also trained, and all the Brain Age models were later applied to a discovery cohort composed of 247 subjects, divided into healthy controls (HC, n=82), episodic migraine (EM, n=91), and chronic migraine patients (CM, n=74).ResultsCM patients showed an increased Brain Age Gap compared to HC (4.16 vs -0.56 years, P=0.01). A smaller Brain Age Gap was found for EM patients, not reaching statistical significance (1.21 vs -0.56 years, P=0.19). No associations were found between the Brain Age Gap and headache or migraine frequency, or duration of the disease. Brain imaging features that have previously been associated with migraine were among the main drivers of the differences in the predicted age. Also, the separate analysis using only morphological or intensity-based features revealed different patterns in the Brain Age biomarker in patients with migraine.ConclusionThe brain-predicted age has shown to be a sensitive biomarker of CM patients and can help reveal distinct aging patterns in migraine.

Modeling Monthly Migraine-Day Distributions Using Longitudinal Regression Models and Linking Quality of Life to Inform Cost-Effectiveness Analysis: A Case Study of Fremanezumab in Japanese-Korean Migraine Patients.

As regression approaches have been used more recently to model the effectiveness and health-related quality of life (HRQOL) of novel migraine treatments, an example is provided for fremanezumab. The objective is to estimate the distribution of mean monthly migraine days (MMD) as a continuous variable and corresponding migraine-specific utility values as a function of the MMD, to inform health states in a cost-effectiveness model (CEM). Three longitudinal regression models (zero-adjusted gamma [ZAGA], zero-inflated beta-binomial [ZIBB], and zero-inflated negative binomial [ZINBI]) were fitted to Japanese-Korean clinical trial data of episodic (EM) and chronic migraine (CM) patients treated with fremanezumab or placebo, to estimate MMD over a period of 12 months. The EQ-5D-5L and the migraine-specific quality-of-life (MSQ), mapped to the EQ-5D-3L, questionnaires were used to measure HRQOL. Migraine-specific utility values were estimated as a function of MMD using a linear mixed effects model. The ZIBB models fitted the data best in estimating the distribution of mean MMD over time. MSQ-derived values were more sensitive than the EQ-5D-5L values for the effect of the number of MMD on HRQOL, with higher values for less MMD and more time on treatment. Using longitudinal regression models to estimate MMD distributions and linking utility values as a function is an appropriate method to inform CEMs and capture inter-patient heterogeneity. The observed distribution shifts demonstrated fremanezumab's effect at reducing MMD for both EM and CM patients, while treatment effect on HRQOL was captured by MMD and time on treatment.

A cross-sectional study on the personality traits of episodic and chronic migraine patients.

Migraine, is a common neurological disorder that may be associated with certain personality traits. This study aims to identify and compare the personality traits accompanying the clinical and sociodemographic profiles in migraine groups. The study included a cohort of chronic, episodic migraine (CM - EM) and healthy controls (HC). Migraine was diagnosed according to the International Classification of Headache Disorders-3β criteria. Age, gender, migraine-related disease duration, number of days with a headache each month, and headache intensity of the patients were recorded. The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) was used to determine personality traits. The study groups were similar in terms of sociodemographic characteristics (70 CM, 70 EM, and 70 HC). The visual analog scale (VAS) score was significantly higher in CM (p<0.05). No statistically significant difference was found between the groups concerning symptoms of migraine such as osmophobia, photophobia, phonophobia, and nausea (p>0.05). When the personality traits were examined, the mean scores of the MMPI test results of migraine patients were found to be higher than healthy controls in line personality disorders (p<0.05 for all personality traits). In CM patients, the 'hysteria' score was found to be higher in subgroup evaluation (p<0.05). EM and CM patients had more evidence of personality disorders than healthy controls. CM patients had higher hysteria scores than EM patients. In addition to pain treatment, determining personality traits and providing appropriate management with a multidisciplinary approach can benefit both in terms of treatment, cost, and time.

Telomere-related genes as potential biomarkers to predict endometriosis and immune response: Development of a machine learning-based risk model.

Endometriosis (EM) is an aggressive, pleomorphic, and common gynecological disease. Its clinical presentation includes abnormal menstruation, dysmenorrhea, and infertility, which seriously affect the patient's quality of life. However, the pathogenesis underlying EM and associated regulatory genes are unknown. Telomere-related genes (TRGs) were uploaded from TelNet. RNA-sequencing (RNA-seq) data of EM patients were obtained from three datasets (GSE5108, GSE23339, and GSE25628) in the GEO database, and a random forest approach was used to identify telomere signature genes and build nomogram prediction models. Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, and Gene Set Enrichment Analysis were used to identify the pathways involved in the action of the signature genes. Finally, the CAMP database was used to screen drugs for potential use in EM treatment. Fifteen total genes were screened as EM-telomere differentially expressed genes. Further screening by machine learning obtained six genes as characteristic predictive of EM. Immuno-infiltration analysis of the telomeric genes showed that expressions including macrophages and natural killer cells were significantly higher in cluster A. Further enrichment analysis showed that the differential genes were mainly enriched in biological pathways like cell cycle and extracellular matrix. Finally, the Connective Map database was used to screen 11 potential drugs for EM treatment. TRGs play a crucial role in EM development, and are associated with immune infiltration and act on multiple pathways, including the cell cycle. Telomere signature genes can be valuable predictive markers for EM.

Annual indirect costs savings in patients with episodic or chronic migraine: a post-hoc analysis of phase 3 galcanezumab clinical trials in the United States

BackgroundGalcanezumab (GMB) improved quality-of-life and reduced disability of patients with episodic (EM) and chronic migraine (CM) in Phase 3 trials.AimTo estimate indirect cost savings associated with GMB treatment in patients with migraine in the United States (US).MethodsWe analyzed data of patients from the US from three randomized, Phase 3, double-blind, placebo (PBO)-controlled GMB studies: EVOLVE-1 and EVOLVE-2 (EM patients), REGAIN (CM patients). Annual indirect costs were calculated using items of the Migraine Disability Assessment (MIDAS) questionnaire: lost time/productivity at work/school, household work, and leisure time. All costs were annualized and expressed in 2019 US dollars. While the main analysis considered lost time/productivity at work/school and household work as a full day, a sensitivity analysis was performed by discounting them by half. For EM, annual indirect costs savings were estimated using mixed model repeated measures analysis. For CM, ANCOVA models were used to estimate annual indirect costs savings as change from baseline.ResultsThe analysis included 805 patients with EM (mean age = 41.4 years; PBO = 534; GMB = 271) and 423 patients with CM (mean age = 38.9 years; PBO = 279; GMB = 144). Compared to PBO, GMB significantly reduced annual indirect costs among patients with EM at 3 months (least square mean [95% confidence interval] work/school = $1,883.6 [603.64–3,163.65], p = .0040, household work = $628.9 [352.95–904.88], p <.0001, and leisure activity = $499.17 [42.36–955.98], p = .0323) and 6 months (work/school = $2,382.29 [1,065.48–3,699.10], p = .0004, household work = $559.45 [268.99–849.90], p = .0002, and leisure activity = $753.81 [334.35–1,173.27], p = .0004), whereas a significant difference was not observed among patients with CM. Sensitivity analysis results were similar to primary analysis results.ConclusionsGMB treatment versus PBO resulted in significantly greater indirect cost savings in patients with EM through improved productivity at work/school, household work, and leisure days. Patients with CM receiving GMB versus PBO attained greater cost savings, although not statistically significant, through reduced lost productivity at work/school.

Behavioral and psychological factors in individuals with migraine without psychiatric comorbidities

BackgroundIt is well known that the course of migraine is influenced by comorbidities and that individual psychological characteristics may impact on the disease. Proper identification of psychological factors that are relevant to migraine is important to improve non-pharmacological management. This study aimed at investigating the relationship between psychological factors and migraine in subjects free of psychiatric comorbidities.MethodsA sample of women with episodic (EM) and chronic migraine (CM) without history of psychiatric comorbidities were included in this cross-sectional study. The study also included female healthy controls (HC) without migraine or other primary headaches. We evaluated sleep, anxiety, depression, intolerance of uncertainty, decision making style and tendence to pain catastrophizing by validated self-report questionnaires or scales. Comparisons among groups were performed using ANOVA and Bonferroni post-hoc tests. Statistical significance was set at p < 0.05.ResultsA total of 65 women with EM (mean age ± SD, 43.9 ± 7.2), 65 women with CM (47.7 ± 8.5), and 65 HC (43.5 ± 9.0) were evaluated. In sleep domains, CM patients reported poorer overall sleep quality, more severe sleep disturbances, greater sleep medication use, higher daytime dysfunction, and more severe insomnia symptoms than HC. EM group showed better sleep quality, lower sleep disturbances and sleep medication use than CM. On the other hand, the analysis highlighted more severe daytime dysfunction and insomnia symptoms in EM patients compared to HC. In anxiety and mood domains, CM showed greater trait anxiety and a higher level of general anxiety sensitivity than HC. Specifically, CM participants were more afraid of somatic and cognitive anxiety symptoms than HC. No difference in depression severity emerged. Finally, CM reported a higher pain catastrophizing tendency, more severe feeling of helplessness, and more substantial ruminative thinking than EM and HC, whilst EM participants reported higher scores in the three above-mentioned dimensions than HC. The three groups showed similar decision-making styles, intolerance of uncertainty, and strategies for coping with uncertainty.ConclusionsEven in individuals without psychiatric comorbidities, specific behavioral and psychological factors are associated with migraine, especially in its chronic form. Proper identification of those factors is important to improve management of migraine through non-pharmacological strategies.

The Performance of Nine Commercial Serological Screening Assays for the Diagnosis of Lyme Borreliosis: a Multicenter Modified Two-Gate Design Study.

ABSTRACTIn this retrospective study, the performance of nine serological screening assays for Lyme borreliosis (LB) diagnostics was evaluated using a study population of LB cases and controls. Sera derived from 74 well-defined LB cases and 122 controls were included. The LB cases were diagnosed with erythema migrans (EM; n = 11), Lyme neuroborreliosis (LNB; n = 35), Lyme arthritis (LA; n = 20), or acrodermatitis chronica atrophicans (ACA; n = 8). Controls comprised 74 age- and gender-matched healthy individuals and 48 patients with other diseases with anticipated high rates of cross-reactivity. The assays under evaluation were selected based on a literature review and expected continued availability with CE marking under the new in vitro diagnostic regulation (European Union) 2017/746. The overall sensitivity (IgG and IgM results combined) among LB cases ranged between 54.5% (6 of 11) and 90.9% (10 of 11) for EM patients and between 97.1% (34 of 35) and 100% for patients with LNB, LA, and ACA. The positivity rate ranged between 8.1% (6 of 74) and 29.7% (22 of 74) among the healthy controls and between 22.9% (11 of 48) and 64.6% (31 of 48) among the cross-reactivity controls. The IgM results were more heterogeneous than the IgG and IgM/IgG results and did not contribute to the overall sensitivity but substantially increased the positivity rates among the controls. In conclusion, all evaluated Borrelia serological screening assays performed comparably with respect to early- and late-disseminated LB. The addition of an IgM assay to the screening of Borrelia-specific IgG antibodies had no added value for the diagnosis of Lyme borreliosis.IMPORTANCE Serology plays an important role in the diagnosis of Lyme borreliosis. Guidelines prescribe a two-tier testing algorithm in which a highly sensitive screening assay is used for screening and reactive sera are retested with an immunoblot to reduce false positivity rates. Recently, two commonly used screening assays were discontinued, including the very well-performing C6 Lyme enzyme-linked immunosorbent assay (ELISA) (Immunetics). This study provides an evaluation of the performance of nine different Borrelia serology screening assays, eight with expected future availably and the C6 Lyme ELISA, using a well-defined study panel of Lyme borreliosis patients, healthy population controls, and cross-reactivity controls. Evaluation data on multiple assays aid diagnostic laboratories in their choice for a reliable Borrelia serology screening assay to improve their diagnostic algorithm for Lyme borreliosis.

Eptinezumab for migraine prevention in patients 50 years or older.

ObjectiveTo evaluate the efficacy and safety of eptinezumab versus placebo in patients ≥50 years old with episodic (EM) or chronic migraine (CM).Materials and MethodsThis post hoc analysis included data from two phase 3, parallel‐group, randomized, double‐blind, placebo‐controlled studies in adults with EM (PROMISE‐1) or CM (PROMISE‐2). Patients ≥50 years at baseline treated with eptinezumab 100 mg, 300 mg, or placebo were pooled from both studies to evaluate efficacy and safety.ResultsA total of 385/1960 (19.6%) EM and CM patients who were ≥50 years old at baseline (range, 50–71 and 50–65 years, respectively) received eptinezumab 100 mg (n = 132), 300 mg (n = 127), or placebo (n = 126) over Weeks 1–12. Reductions in mean monthly migraine days (MMDs) in ≥50‐year‐old EM patients were –3.8 (100 mg) and –4.4 (300 mg) with eptinezumab versus –2.6 with placebo. In ≥50‐year‐old CM patients, mean changes in MMDs were –7.7 (100 mg) and –8.6 (300 mg) with eptinezumab versus –6.0 with placebo. Changes in MMDs were comparable to total study results. A ≥50% MMD reduction over Weeks 1–12 was achieved by 57.9% of eptinezumab‐treated versus 35.7% of patients who received placebo, and a ≥75% reduction by 30.5% versus 13.5%, respectively. The incidence of treatment‐emergent adverse events (TEAEs) in EM and CM patients ≥50 years old was similar across treatment groups, with ≥96% of TEAEs mild or moderate in severity.ConclusionsTreatment with eptinezumab was efficacious, tolerable, and safe in patients ≥50 years with EM or CM, congruent with results from the overall study population.

Patient-reported outcomes, health-related quality of life, and acute medication use in patients with a\u2009\u2265\u200975% response to eptinezumab: subgroup pooled analysis of the PROMISE trials

BackgroundPROMISE-1 and PROMISE-2 evaluated the preventive efficacy, tolerability, and safety of eptinezumab, a calcitonin gene-related peptide–targeted monoclonal antibody, in adults with episodic (EM) and chronic migraine (CM), finding significant reductions in migraine frequency. This post hoc analysis compared patient-reported outcomes (PROs), health-related quality of life (HRQoL) and acute medication use in patients with a ≥ 75% migraine responder rate (MRR) after treatment with eptinezumab to patients with a ≥ 50– < 75% MRR.MethodsPROMISE-1 and PROMISE-2 were phase 3, randomized, double-blind, placebo-controlled studies. This analysis included patients from both studies treated with eptinezumab 100 mg or 300 mg who experienced ≥ 75% and ≥ 50–< 75% MRR over Weeks 1–12 (wks1–12). In both studies, HRQoL was measured by the 36-item Short-Form Health Survey (SF-36) and acute medication usage. PROMISE-2 also included the 6-item Headache Impact Test (HIT-6), patient-identified most bothersome symptom (PI-MBS), and Patient Global Impression of Change (PGIC).ResultsIn PROMISE-1, a total of 115/443 (26.0%; 100 mg, n = 49, 300 mg, n = 66) and 120/443 (27.0%; 100 mg, n = 61, 300 mg, n = 59) eptinezumab-treated patients achieved ≥ 75% and ≥ 50–< 75% MRR over wks1–12, respectively. In PROMISE-2, a total of 211/706 (30.0%; 100 mg, n = 95; 300 mg, n = 116) and 209/706 (29.6%; 100 mg, n = 110, 300 mg, n = 99) eptinezumab-treated patients achieved ≥ 75% and ≥ 50–< 75% MRR over wks1–12, respectively. EM and CM patients with ≥ 75% and ≥ 50–< 75% MRR over wks1–12 showed reduced use of acute headache medication and increased HRQoL to normative levels across SF-36 domains of bodily pain, social functioning, and physical functioning. In CM patients with ≥ 75% and ≥ 50–< 75% MRR over wks1–12, the mean change in HIT-6 total score with eptinezumab (pooled) was − 11.7 and − 7.6, respectively. “Very much” or “much” improvement responses were reported in 41.8% and 16.5% on PI-MBS and 36.2% and 20.0% on PGIC in ≥ 75% and ≥ 50–< 75% MRR, respectively.ConclusionEptinezumab treatment induced a ≥ 75% MRR over wks1–12 in the majority of patients. This patient subgroup reported substantial improvements in PROs associated with headache-related life impact and HRQoL, and reductions in acute headache medication use, which were more marked than those in the ≥ 50–< 75% responders. This study supports the clinical meaningfulness of ≥ 75% MRR for patients with either EM or CM.Trial registrationClinicalTrials.gov identifiers: NCT02559895 (PROMISE-1), NCT02974153 (PROMISE-2).

Tick-transmitted co-infections among erythema migrans patients in a general practice setting in Norway: a clinical and laboratory follow-up study

BackgroundErythema migrans (EM) is the most common manifestation of Lyme borreliosis. Here, we examined EM patients in Norwegian general practice to find the proportion exposed to tick-transmitted microorganisms other than Borrelia, and the impact of co-infection on the clinical manifestations and disease duration.MethodsSkin biopsies from 139/188 EM patients were analyzed using PCR for Neoehrlichia mikurensis, Rickettsia spp., Anaplasma phagocytophilum and Babesia spp. Follow-up sera from 135/188 patients were analyzed for spotted fever group (SFG) Rickettsia, A. phagocytophilum and Babesia microti antibodies, and tested with PCR if positive. Day 0 sera from patients with fever (8/188) or EM duration of ≥ 21 days (69/188) were analyzed, using PCR, for A. phagocytophilum, Rickettsia spp., Babesia spp. and N. mikurensis. Day 14 sera were tested for TBEV IgG.ResultsWe detected no microorganisms in the skin biopsies nor in the sera of patients with fever or prolonged EM duration. Serological signs of exposure against SFG Rickettsia and A. phagocytophilum were detected in 11/135 and 8/135, respectively. Three patients exhibited both SFG Rickettsia and A. phagocytophilum antibodies, albeit negative PCR. No antibodies were detected against B. microti. 2/187 had TBEV antibodies without prior immunization. There was no significant increase in clinical symptoms or disease duration in patients with possible co-infection.ConclusionsCo-infection with N. mikurensis, A. phagocytophilum, SFG Rickettsia, Babesia spp. and TBEV is uncommon in Norwegian EM patients. Despite detecting antibodies against SFG Rickettsia and A. phagocytophilum in some patients, no clinical implications could be demonstrated.

Clinical Features and Long-Term Outcomes After Laparoscopic Surgery in Patients Co-existing With Endometriosis and Adenomyosis.

Objective: To investigate the difference of clinical features and outcomes between EM patients with and without AM after following up for at least 6 years after surgery.Methods: We retrospectively analyzed 358 EM patients who had a minimum of 6 years follow-up after laparoscopic cystectomy, which was performed by one single doctor at Peking Union Medical College Hospital from January 2009 to April 2013. All women were divided into AM group and non-AM group and analysis was performed in preoperative characteristics, surgical findings and postoperative outcomes during follow-up.Results: A total of 358 EM patients were recruited, of which 142 (39.7%) were in the AM group and the rest 216 (60.3%) in the non-AM group. Between the two group, the mean age was 34.6 vs. 32.2 years (P < 0.001). The mean operating time in the AM and non-AM group was 73.2 vs. 61.9 min (P < 0.001). According to the revised AFS classification, the mean score of the two group were 60.3 vs. 45.5 (P < 0.001). At the end of the follow-up, though the AM group was with higher rate of disease relapse, yet no significant difference was found between the two groups in statistical comparison (34/142 [23.9%] vs. 34/216 [15.7%], P = 0.053). With a minimum follow-up of 6 years after laparoscopic cystectomy, failed and successful pregnancy were seen in 107/142(75.4%) and 35/142 (24.6%) patients in the AM group vs. 114/216(52.8%) and 102/216 (47.2%) patients in the non-AM group (P < 0.05). As for the successfully pregnant patients, live births, including spontaneous pregnancy and IVF-ET, were seen in 34/35 (97.1) vs. 99/102 (97.1) patients between AM and non-AM groups, while others ended in spontaneous abortion. No significant associations were found between the two groups in infertility, leiomyoma presence, the size of ovarian endometrioma, type of deep infiltrating endometriosis (DIE) or type of recurrence (P > 0.05).Conclusion: Compared with non-AM group, EM patients with concurrent AM may have higher age, longer mean operating time and higher mean AFS score. In terms of fertility outcomes, patients in the AM group were with lower likelihood of pregnancy after surgery during the long-time follow-up.
