Article

The theme of the articles this month is migraine and blood vessels. Migraine is a known risk factor for vascular events, it is a known vasodilatory phenomenon, and it is commonly treated with vasoconstrictive medications. Genetic studies are further elucidating the connection between migraine and vascular risk factors. The following studies take this vascular connection to clinical relevance in different ways.

Previous studies have investigated the combination of simvastatin and vitamin D for migraine prevention. Statins have anti-inflammatory properties and migraine can partially be understood as an inflammatory vascular phenomenon. Vitamin D and simvastatin were previously shown to be effective in a randomized trial; this study¹ investigated the combination of atorvastatin with nortriptyline for migraine prevention. Patients were excluded if they had a vitamin D deficiency.

This was a triple-blinded study with one control group, one placebo plus notriptyline group, and one atorvastatin plus nortiptyline group. The nortiptyline dosage was 25mg nightly, and the interventions were given for 24 weeks. The primary outcome was decrease in headache day frequency; secondary outcomes were severity and quality of life as measured by the Migraine-Specific Quality of Life Questionnaire (MSQ).

Migraine frequency was seen to be significantly improved after 24 weeks in the statin group; however severity was not significantly affected. Adverse effects were mild and overall no subjects discontinued due to the intervention. Quality of life was also seen to be better in the combination statin/nortriptyline group.

The results of this study are compelling enough to consider the addition of a tricyclic antidepressant (TCA) for a patient already on a statin or to start a statin (in the appropriate clinical setting) on a patient already on a TCA. The main limiting factor may be the hesitation to use a TCA medication in an older patient, where the anticholinergic effects may be less predictable.

Caffeine has a controversial place in the headache world. Many patients either use caffeine as a way to treat their migraine attacks, or avoid it completely as they are told it is a migraine trigger. Most headache specialists recommend the avoidance of excessive caffeine use (typically considered >150 mg daily) and tell their patients to be consistent about when they consume caffeine. The effect of caffeine on migraine likely is due to its vasoactive property, specifically that it is vasoconstrictive in nature. These vasoactive properties may also be why many studies investigating cerebrovascular reactivity have been inconclusive in the past.

The authors in this study² recruited patients with episodic migraine and divided them based on caffeine use. All subjects underwent transcranial Doppler testing at baseline and after 3 months, caffeine users were instructed to discontinue caffeine in the interim. Doppler testing looked for differences in BHI (breath holding index) of the bilateral posterior cerebral arteries (PCA), which is a standard at their institution. Subjects were only investigated if they were headache-free and had not used a migraine abortive medication in the previous 48 hours. Preventive medications were not controlled for.

Although the investigators recommended discontinuation of caffeine for the caffeine users, only 28% of that subgroup did discontinue. They then subdivided the group of caffeine users into those whose caffeine intake increased, decreased, or stayed the same. Transcranial Doppler testing was performed in all subgroups.

The investigators found a lower BHI-PCA, or decrease in vasodilatory function, in the subgroups that remained on caffeine. Those who stopped caffeine had improvement in this metric, showing the possible reversibility that discontinuation of caffeine can have. It remains unclear precisely how caffeine is vasoactive, and the effects may be via adenosine receptors, endothelial function, neurotransmitter production, or regulation of the autonomic nervous system. The long-term vascular effects of caffeine are unknown, but they do appear to be reversible after a 3 month period.

Migraine, and especially migraine with aura, is well known as a vascular risk factor. The presence of migraine increases the odds ratio of stroke, myocardial ischemia, deep vein thrombosis and other vascular events significantly. The American College of Obstetrics and Gynecology recommends avoiding the use of any estrogen containing medication in the presence of migraine, due to estrogen itself being a pro-thrombotic hormone.  The precise mechanism that leads to this increased risk is unknown.

This study investigated the connection between migraine and large artery atherosclerosis (LAA). This group observed 415 consecutive patients aged 18-54 who presented for a first time ischemic stroke (other neurovascular events, such as cerebral venous sinus thrombosis, subarachnoid hemorrhage with secondary ischemia and transient ischemic attacks, were excluded). Data regarding these patient’s risks factors was collected and analyzed including elevated body mass index (BMI), hypertension, diabetes, tobacco use, and hyperlipidemia.

All patients underwent magnetic resonance imaging (MRI), as well as either magnetic resonance angiography (MRA) or computed tomography angiography (CTA), and duplex ultrasound confirmed the images. Atherosclerosis was classified using a standardized system (ASCOD: atherosclerosis, small-vessel disease, cardiac pathology, other causes, and dissection) that grades atheroslerotic lesions on a 0-3 scale.

The results may be considered counterintuitive. The presence of migraine was negatively associated with the presence of LAA: a history of migraine did not increase the risk of atherosclerosis. This was even the case when controlling for the traditional vascular risk factors. The authors theorize that likely the association between migraine and stroke and other vascular events is not related to atherosclerosis and may be due to other causes.

A genome-wide association study recently identified a specific polymorphism that was shared by migraine and coronary artery disease. But just like this study, the people with migraine had a negative association with coronary artery disease. If people with migraine do develop stroke or other vascular phenomena they typically present younger and healthier, and this may be why this negative correlation exists.

Mucous membrane pemphigoid with esophageal web stricture. 

Additional laboratory examination showed that his serum anti-BP180 antibody level was high (11.7 U/mL; normal range, <9.0 U/mL). Biopsy specimens taken from the laryngopharyngeal erosion showed subepithelial blister formation and it was consistent with pemphigoid pathologically (Figure D). He did not have cutaneous lesions and was diagnosed with mucous membrane pemphigoid (MMP). After performing endoscopic dilation, prednisolone (20 mg/d) was administered orally. Three months after starting the prednisolone treatment, follow-up endoscopy showed improvements of the laryngopharyngeal erosions (Figure E) and esophageal blister on the web. However, esophageal narrowing remained, and thus endoscopic balloon dilation was performed (Figure F-H). Three months after the dilation, the narrowing improved (Figure I).

The influence of sex and gender on psoriatic arthritis (PsA) continues to be of interest. Using data from the Dutch south-west Early Psoriatic Arthritis cohort (DEPAR), Passia et al¹assessed sex-related differences in demographics, disease characteristics, and evolution over 1 year in 273 men and 294 women newly diagnosed with PsA. They found that at baseline, women had a significantly longer duration of symptoms, higher tender joint count and enthesitis, higher disease activity, higher levels of pain, more severe limitations in function and worse quality of life. During the 1 year follow up, composite measures of disease activity declined in men and women, but women continued to have higher levels than men. At the end of 1 year, fewer women achieved the criteria for minimal disease activity (MDA). Thus, the disease burden of PsA was higher in women vs. men at all time points and even after 1 year of standard-of-care treatment. Sex-specific treatment strategies might help a higher proportion of women achieve MDA.

Although, enthesitis is believed to be a primary pathogenetic lesion in PsA, the relationship between active enthesitis and disease severity as measured by the presence of joint erosions is less well studied. In a cross-sectional study of 104 PsA patients, Smerilli et al² explored the association between ultrasound (US) entheseal abnormalities and the presence of US detected bone erosions in PsA joints. At least 1 joint bone erosion was found in 45.2% of patients and was associated with power Doppler signal at enthesis (odds ratio [OR] 1.74; P < .01), entheseal bone erosions (OR 3.17; P = .01), and greyscale synovitis (OR 2.59; P = .02). Thus, Doppler signal and bone erosions at entheses indicate more severe PsA and patients with such abnormalities should therefore be treated aggressively.

Comorbidities and associated conditions were a focus of several publications last month. Venous thromboembolism (VTE) is associated with inflammatory diseases, including PsA. In a retrospective cohort study including 5,275 patients with newly diagnosed PsA, Gazitt et al³ assessed the association between PsA and VTE events using a large population-based database in Israel. During follow-up, 1.2% vs. 0.8% patients in the PsA vs. control group were diagnosed with VTE, but this association was not statistically significant after adjusting for demographic factors and comorbidities (adjusted hazard ratio [aHR] 1.27; P = .16) with only older age (aHR 1.08; P < .0001) and history of VTE (aHR 31.63; P < .0001) remaining associated with an increased risk for VTE. Thus, VTE in patients with PsA may be associated with underlying comorbidities rather than PsA per se. In another study, Harris et al⁴demonstrated that PsA was associated with increased risk of endometriosis. In an analysis of 4112 patients with laparoscopically confirmed endometriosis from the Nurses’ Health Study II, they found that psoriasis with concomitant PsA was associated with increased risk for subsequent endometriosis (HR 2.01; 95% CI 1.23-3.30), which persisted even after adjusting for comorbidities. Finally, in a cross-sectional study using data from 1862 juvenile PsA (jPsA) patients (122 [6.6%] of whom developed uveitis) in the German National Pediatric Rheumatological Database, Walscheid et al⁵ showed that patients with jPsA were more likely to develop uveitis if they were diagnosed with PsA at a younger age or were antinuclear antibody positive, with higher disease activity being the only factor significantly associated with the presence of uveitis.

Finally, in a cross-sectional study using data from 1862 juvenile PsA (jPsA) patients (122 [6.6%] of whom developed uveitis) in the German National Pediatric Rheumatological Database, Walscheid et al⁵ showed that patients with jPsA were more likely to develop uveitis if they were diagnosed with PsA at a younger age or were antinuclear antibody positive, with higher disease activity being the only factor significantly associated with the presence of uveitis.

The recent ORAL Surveillance trial has raised concerns about the safety of tofacitinib (and potentially other JAK inhibitors) in the treatment of rheumatoid arthritis.¹ JAK inhibitors are known to increase cholesterol levels; however, this was not previously known to increase cardiovascular risk. The ORAL Surveillance trial was an open-label randomized non-inferiority trial comparing 5mg or 10 mg tofacitinib twice daily with tumor necrosis factor (TNF) inhibitor use. Both adverse cardiac events and cancer were increased in the tofacitinib groups (with hazard ratios of 1.33 and 1.48, respectively). The study did not include a control group and so the impact of RA itself on cardiac events and cancer is not known. However, the apparent risk was greatest in patients over the age of 65, suggesting caution should be used in treating older patients with RA with JAK inhibitors. Interestingly, the STAR-RA study, an observational cohort study, looked at claims data from several sources to try to replicate trial results as well as provide real-world evidence on the topic of cardiovascular risk associated with tofacitinib use.² The authors were able to replicate the inclusion/exclusion criteria from the ORAL Surveillance trial and found that the results were similar. However, on “relaxing” inclusion and exclusion criteria, ie, the “real-world evidence” cohort, there was no difference in incidence of cardiovascular outcomes between tofacitinib and TNF-inhibitor groups. Specifically, patients in the real-world cohort who had no cardiovascular risk factors or prior events were not found to have an increased cardiovascular risk with tofacitinib use, a reassuring finding supporting careful attention to cardiovascular risk in patients with RA when evaluating treatment options.

One consideration in the use of rituximab for treatment of RA is the possibility of changing or lowering subsequent or maintenance doses. Past studies have suggested that halving the dose of rituximab to a single 1000 mg infusion was tolerated by RA patients. The REDO trial, published in 2019, looked at even lower doses: 500 mg and 200 mg. The study did not establish non-inferiority of lower doses at 6 months in a per-protocol analysis, only in intention-to-treat. An extension study of REDO presented at the ACR Convergence in 2021 looked at a subset of those patients for up to 4 years and did find non-inferiority in terms of disease activity. Wientjes et al³ present further analysis of the REDO trial with 140 RA patients at 6 months, looking at the association of rituximab dosage with B cell counts as well as the predictive value of different patient characteristics in terms of response to lower dosages. Interestingly, serum drug levels and B cell counts at 3 and 6 months did not predict response to rituximab, nor did patient characteristics, such as age, smoking, disease, duration, or seropositivity for RF and CCP. Though the authors suggest that this implies even lower doses may be effective, it is not clear, and a similar analysis of the extension trial would be of interest. 

Use of methotrexate as a first-line DMARD for RA is cost-effective but often limited by patient fears or intolerance due to adverse events (AE). This observational cohort study by Sherbini et al⁴ evaluates not only the prevalence of AE, but also baseline factors that may predict the development of AE. Over 1,000 patients with early RA initiating methotrexate were included in analysis. More than 75% reported at least one AE in 12 months, with gastrointestinal AE, such as nausea, being most prevalent (42%); 18% developed elevated liver enzyme tests (defined as a single reading above the upper limit of normal). Few strong predictors of AE were identified, though women were overall more likely than men to report AE. Reassuringly, combination conventional synthetic DMARD therapy did not generally lead to more reported AE. Given the few predictive findings from this study, analysis of a comparator group or comparison of AE at different starting and maintenance doses of methotrexate would be of interest.

The predilection for brain metastases in human epidermal growth factor receptor 2 (HER2)-positive breast cancer has historically presented a therapeutic challenge, and agents with enhanced central nervous system (CNS) penetrance are certainly desired. Pyrotinib is a small molecule irreversible tyrosine kinase inhibitor against epidermal growth factor receptor (EGFR), HER2, and HER4. Yan et al investigated the activity and safety of pyrotinib + capecitabine in the single-arm, two-cohort, phase 2 PERMEATE study among 78 patients with HER2-positive metastatic breast cancer (MBC) with brain metastases. The intracranial objective response rate was 74.6% in radiotherapy-naive patients and 42.1% in those progressing after prior radiotherapy. The combination showed good tolerability with the most common grade 3 treatment-related adverse events of diarrhea and neutropenia. Additional studies have shown impressive CNS activity with other HER2-targeted therapies including tucatinib + capecitabine + trastuzumab combination, as well as trastuzumab deruxtecan (HER2CLIMB and DESTINY-Breast03 trials, respectively). The evolution of these agents in both the metastatic and early settings will continue to transform the treatment algorithm for HER2-positive breast cancer. A particularly interesting concept is whether earlier use of drugs with better CNS efficacy can reduce risk or prevent development of brain metastases.

Endocrine therapy in early-stage hormone receptor-positive (HR+) breast cancer leads to significant reductions in recurrence and breast cancer mortality. A meta-analysis was performed by Early Breast Cancer Trialists' Collaborative Group including four trials (ABCSG XII, SOFT, TEXT and HOBOE), 7030 premenopausal patients with early-stage ER+ breast cancer, who received an aromatase inhibitor or tamoxifen for 3-5 years with ovarian suppression. Rates of breast cancer recurrence were lower with an aromatase inhibitor vs tamoxifen, with the main benefit seen during years 0-4 (relative risk [RR] 0.68, P < .0001) and an absolute reduction in 5-year recurrence risk of 3.2% (6.9% vs 10.1%). Aromatase inhibitor use was associated with decreased distant recurrence risk (RR 0.83), but there was no significant difference for breast cancer or all-cause mortality. The favored endocrine therapy approach for an individual patient is often complex and based on overall risk, comorbidities and toxicity concerns, as well as patient preference. Longer follow-up of trials with endocrine therapy and ovarian suppression will provide further insight on mortality impact.

Aromatase inhibitor (AI)-associated musculoskeletal symptoms are not infrequent and can contribute to treatment discontinuation. Current management practices include use of non-steroidal anti-inflammatory drugs (NSAID), weight loss and exercise, trial of alternative AI or tamoxifen, use of serotonin and norepinephrine reuptake inhibitors (SNRI) (duloxetine) and acupuncture. Martinez et al reported on outcomes of the non-selective NSAID, sulindac (150mg twice daily for 12 months), in a phase 2 study among postmenopausal women with early HR+ breast cancer who were stable on AI therapy for at least 3 months. At 12 months, patients receiving sulindac (n = 43) reported improvements (decreases) in Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index (-5.85, P = .003), pain (-5.40, P = .043), stiffness (-9.53, P < .001) and physical function (-5.61, P = .006); those in the observation group (n = 40) did not experience improvements in these variables. The most significant improvement with sulindac was seen in those with a higher degree of baseline symptoms and in overweight/obese patients. These findings support further investigation into abbreviated NSAID use and strategies focused on exercise and healthy body weight maintenance for breast cancer patients.

The treatment landscape for early-stage triple-negative breast cancer (TNBC) continues to evolve with integration of new drugs into our armamentarium, and use of pathologic complete response (pCR) as a surrogate for outcome and for tailoring adjuvant therapy. Geyer et al reported on event-free survival outcomes with a 4.5 year follow-up of the phase 3 BrighTNess trial, which included 634 patients with stage II-III TNBC. Significant improvement in event-free survival (EFS) was seen in the carboplatin + veliparib + paclitaxel arm vs. paclitaxel alone (HR 0.63, P = .02), but no difference in EFS in carboplatin + veliparib + paclitaxel vs. carboplatin + paclitaxel (HR 1.12, P = .62). The EFS rates at 4 years were 78% (carboplatin + veliparib + paclitaxel), 79% (carboplatin + paclitaxel) and 69% (paclitaxel alone). The phase 3 KEYNOTE-522 trial demonstrated improvement in EFS with the addition of neoadjuvant pembrolizumab to chemotherapy (carboplatin/paclitaxel followed by AC) followed by adjuvant pembrolizumab compared to chemotherapy alone in patients with stage II-III TNBC. The emergence of new therapies for early TNBC, including immunotherapy and  poly (ADP-ribose) polymerase (PARP) inhibitors (the latter for patients with germline BRCA mutations), has created more treatment options for patients along with questions regarding combinations and sequencing.

The treatment landscape for early-stage triple-negative breast cancer (TNBC) continues to evolve with integration of new drugs into our armamentarium, and use of pathologic complete response (pCR) as a surrogate for outcome and for tailoring adjuvant therapy. Geyer et al reported on event-free survival outcomes with a 4.5 year follow-up of the phase 3 BrighTNess trial, which included 634 patients with stage II-III TNBC. Significant improvement in event-free survival (EFS) was seen in the carboplatin + veliparib + paclitaxel arm vs. paclitaxel alone (HR 0.63, P = .02), but no difference in EFS in carboplatin + veliparib + paclitaxel vs. carboplatin + paclitaxel (HR 1.12, P = .62). The EFS rates at 4 years were 78% (carboplatin + veliparib + paclitaxel), 79% (carboplatin + paclitaxel) and 69% (paclitaxel alone). The phase 3 KEYNOTE-522 trial demonstrated improvement in EFS with the addition of neoadjuvant pembrolizumab to chemotherapy (carboplatin/paclitaxel followed by AC) followed by adjuvant pembrolizumab compared to chemotherapy alone in patients with stage II-III TNBC. The emergence of new therapies for early TNBC, including immunotherapy and  poly (ADP-ribose) polymerase (PARP) inhibitors (the latter for patients with germline BRCA mutations), has created more treatment options for patients along with questions regarding combinations and sequencing.

Key clinical point: Atogepant shows a favorable safety and efficacy profile in the prophylactic treatment of episodic migraine.

Major finding: Atogepant (10 mg, 30 mg, and 60 mg) vs. placebo caused a significant reduction in mean monthly migraine (P < .00001, P < .00001, and P = .007; respectively), headache (P < .00001, P < .00001, and P = .001; respectively), and medication use (all P < .00001) days; an increase in the ≥50% responder rate (P = .0008, P = .02, and P = .04; respectively); and a nonsignificant difference in the outcomes of adverse events (P = .57, P = .64, and P = .68; respectively).

Study details: Findings are from a meta-analysis of 3 randomized controlled trials including 2,466 adult patients with episodic migraine who received atogepant (10 mg, 30 mg, or 60 mg once daily) or placebo.

Disclosures: The study was supported by the Suzhou Health Talents Training Project. None of the authors declared any conflicts of interest.

Key clinical point: Discontinuation of anticalcitonin gene-related protein (CGRP) monoclonal antibodies (mAb) leads to a progressive increase in monthly migraine days (MMD) and analgesic use from the first month, which, on reinitiation, revert to values comparable with those in the last month of treatment.

Main finding: At months 2 and 3 after discontinuation, a significant increase in MMD (P = .003 and P < .001, respectively) and analgesic use (both P < .001) was observed compared with month 12 of treatment. In the reinitiation month, the MMD (P = .40), days with ≥1 analgesic used (P = .83), and number of analgesics used (P = .74) were similar to the treatment month 12 values.

Study details: Findings are from a single-center, prospective, observational study involving 44 patients >18 years of age with treatment-resistant chronic migraine who received erenumab or galcanezumab for 12 months before a 3-month treatment discontinuation phase and 1 month of reinitiation.

Disclosures: The study received no specific funding. Some authors reported receiving personal fees or grants from various sources.

Key clinical point: The efficacy and safety of eptinezumab in preventing migraine realized in the PROMISE-1 and PROMISE-2 trials remain unperturbed by the intrinsic baseline characteristics of the study participants, including sex, age, and body mass index (BMI).

Main finding: The ≥50% migraine responder rate (MRR) was ≥10% higher with eptinezumab relative to placebo for most demographic factors, except in the case of obesity; although patients with a BMI of 30-35 kg/m² receiving eptinezumab vs. placebo showed improved ≥50% MRR, the separation was <10%. Eptinezumab was generally safe, and no new treatment-emergent adverse events were identified.

Study details: This was a post hoc subgroup analysis of adult patients with episodic or chronic migraine from the phase 3 PROMISE-1 and PROMISE-2 trials, respectively, which included a total of 1,960 patients in the safety analysis and 1,737 patients (99.8%) in the efficacy analysis.

Disclosures: The study received financial support from H. Lundbeck A/S. The authors disclosed having no conflicts of interest.
