Key clinical point: Baricitinib monotherapy was as effective as baricitinib plus methotrexate therapy with high drug retention rates in patients with rheumatoid arthritis (RA), suggesting baricitinib monotherapy as a viable option in the case of methotrexate intolerance.

Major finding: The 28-joint Disease Activity Scores based on Erythrocyte Sedimentation Rate were not significantly different at all time points over 96 weeks (log-rank P = .44) and drug survival rates at 1 year (69% vs 67%) and 2 years (62% vs 56%) were comparable in the baricitinib alone vs baricitinib+methotrexate arm. No new safety signals were identified.

Study details: This prospective observational study included 139 patients with RA who switched to baricitinib monotherapy or baricitinib plus methotrexate therapy because of high disease activity or intolerance to previous conventional synthetic and biologic disease-modifying antirheumatic drugs.

Disclosures: This study was supported by the Deutsche Forschungsgemeinschaft and other sources. Several authors reported receiving speaker honoraria or travel support or serving as consultants for various sources.

Practice Gap

Cutaneous surgery involves many areas where skin is quite thin and fragile, which often is encountered in elderly patients; the forearms and lower legs are the most frequent locations for thin skin.¹ Dermatologic surgeons frequently encounter these situations, making this a highly practical arena for technical improvements.

For many of these patients, there is little meaningful dermis for placement of subcutaneous sutures. Therefore, a common approach following surgery, particularly following Mohs micrographic surgery in which tumors and defects typically are larger, is healing by secondary intention.² Although healing by secondary intention often is a reasonable option, we have found that maximizing the use of epidermal skin for primary closure can be an effective means of closing many such defects. Antimicrobial reinforced skin closure strips have been incorporated in wound closure for thin skin. However, earlier efforts involving reinforcement perpendicular to the wound lacked critical details or used a different technique.³

The Technique

We developed a novel effective closure technique that minimizes these problems. Our technique has been used on the wounds of hundreds of patients with satisfying results. Early on, we used multiple variations to optimize outcomes, including different sizes of sutures and reinforced skin closure strips, application of medical liquid adhesive, liquid adhesive, and varying postoperative dressings. For 3 years, we tracked outcomes in-house and gradually narrowed down our successes into a single, user-friendly paradigm.

Supplies—To perform this technique, required supplies include:

• 2-0 Polypropylene suture with a PS-2 needle, or the equivalent. Polyglactin or silk suture can be utilized if a less-rigid suture is desired; however, we primarily have used polypropylene for repairs with good results. Each repair requires at least 2 sutures.

• Reinforced skin closure strips (1×5 inches). This width affords increased strength.

• Conforming stretch bandage and elastic self-adherent wrap.

• Polysporin (bacitracin zinc, polymyxin B sulfate, and petrolatum)(Johnson & Johnson).

• All usual surgical instruments and supplies, including paper tape and nonadherent gauze (surgeon dependent).

Step-by-step Technique—Close the wound using the following steps:

1. Once the defect is finalized following Mohs micrographic surgery or excision, excise the ellipse to be utilized for the closure and perform complete hemostasis.

2. Place 2 layers of reinforced skin closure strips—one on top of the other—along each side of the defect, leaving approximately 1 cm of uncovered skin between the wound edges and the reinforced skin closure strips (Figure, A).

3. Take a big-bite pulley suture about one-third of the way from one end of the ellipse, with both punctures passing through the reinforced skin closure strips. Leave that in place or have the assistant hold it and wait. Place a second suture immediately adjacent to the pulley suture. Once that suture is placed but still untied, have the assistant carefully pull the pulley suture outward away from the wound edge while you carefully bring the suture together and tie it off gently (Figure, B). Doing this utilizes the pulley ability of the suture to protect the skin from tearing and releases sufficient pressure on the single suture so that it can be easily tightened without risk to the fragile skin.

4. Repeat step 3, this time placing a pulley suture near the midline of the ellipse and the subsequent single suture adjacent to it.

5. Take pulley sutures repeatedly as in steps 3 and 4 until multiple sutures are secured in place. Replace the pulley sutures with single sutures because the double-pulley sutures in areas of lower vascularity tend to have, in our experience, a slightly increased incidence of focal necrosis in comparison to single sutures.

6. Make a concerted attempt to keep as much blood as possible off the reinforced skin closure strips throughout the procedure; the less dried blood on the reinforced skin closure strips, the cleaner and better the final closure (Figure, C).

7. Most of these cases involve the forearms and the legs below the knees. Because any increase in pressure or swelling on the wound can result in skin breakdown, postoperative dressing is critical. We use a layered approach; the following sequence can be modified to the preference of the surgeon: Polysporin (bacitracin zinc, polymyxin B sulfate, and petrolatum), nonadherent gauze, paper tape, conforming stretch bandage, and elastic self-adherent wrap. Minimizing swelling and infection are the primary goals. The wrap is left on for 1 week and should be kept dry.

8. Have the patient return to the office in 1 week. Unwrap the entire wound; trim back the reinforced skin closure strips; and have the patient utilize typical wound care at home thereafter consisting of cleaning and application of Polysporin or plain petrolatum, nonadherent gauze, and a paper-tape bandage. Because liquid adhesive is not utilized in this technique, the reinforced skin closure strips can be carefully removed without tearing skin. Leave sutures in for 3 weeks for arm procedures and 4 weeks for leg procedures, unless irritation develops or rapid suture overgrowth occurs in either location.

Complications

Most outcomes after using this technique are typical of optimized linear surgeries, with reduced scarring and complete wound healing (Figure, D). We seldom see complications but the following are possible:

• Bleeding occurs but rarely; the weeklong wrap likely provides great benefit.

• Infection is rare but does occur occasionally, as in any surgical procedure.

• Breakdown of the entire wound is rare; however, we occasionally see focal necrosis near 1 stitch—or rarely 2 stitches—that does not require intervention, apart from longer use of topical Polysporin or petrolatum alone to maximize healing by secondary intention in those small areas.• Despite simple suture placement far from the edge of the wound, wound inversion is seldom a problem because these taut closures have a tendency to expand slightly due to postoperative swelling.

Practice Implications

Any experienced dermatologic surgeon can perfect this technique for closing a wound in thin skin. Because wound closure in areas of fragile skin frequently is encountered in cutaneous surgery, we hope that utilizing this technique results in an optimal outcome for many patients.

Key clinical point: The use of conventional disease-modifying antirheumatic drugs did not increase the risk for rheumatoid arthritis-associated interstitial lung disease (RA-ILD) progression, except leflunomide, which increased the risk for ILD-progression in patients with severe ILD.

Major finding: Overall, the use vs no use of methotrexate, tacrolimus, or leflunomide was not associated with an increased risk for ILD progression; however, leflunomide significantly increased the risk for ILD progression in patients with reduced lung function (adjusted hazard ratio 8.42; 95% CI 2.61-27.15).

Study details: This prospective cohort study included 143 patients with RA-ILD who received methotrexate, leflunomide, or tacrolimus.

Disclosures: This study was supported by Seoul National University Hospital and Korea Health Technology R&D Project funded by the Ministry of Health and Welfare, Republic of Korea. The authors declared no conflicts of interest.

Q1. Correct answer: D. Rabeprazole 

Rationale 

Within-class switching of proton pump inhibitors (PPIs) for patients with incomplete control of symptoms is frequently done in clinical practice. For the management of gastroesophageal reflux disease, this practice can be "considered" according to guidelines. More recent data suggest varying potencies of PPIs might be responsible for some patient's incomplete response. When measured as omeprazole equivalents, the relative potencies of standard-dose pantoprazole, lansoprazole, omeprazole, esomeprazole, and rabeprazole have been estimated at 0.23, 0.90, 1.00, 1.60, and 1.82 OEs, respectively.

This patient's clinical presentation of weight gain and associated symptoms are most closely related to a diagnosis of obesity. In addition, her laboratory findings are consistent with common obesity complications, including prediabetes and dyslipidemia, and her blood pressure is borderline high. 

Obesity is a chronic, multifactorial disease with a complex pathogenesis comprising of genetic, biological, psychosocial, socioeconomic, and environmental factors. It is a heterogeneous disease characterized by a dysfunction of the normal pathways and mechanisms that are involved in body fat regulation (often referred to as weight regulation), which may lead to variable presentation and complications. According to the US Centers for Disease Control and Prevention, the highest age-adjusted prevalence of obesity is seen in non-Hispanic Black adults (49.9%), followed by Hispanic adults (45.6%), non-Hispanic White adults (41.4%), and non-Hispanic Asian adults (16.1%).

Epidemiologic studies have defined obesity as a BMI > 30, which is then subclassified into class 1 (BMI of 30-34.9), class 2 (BMI of 35-39.9), or class 3 (BMI ≥ 40) obesity. Though BMI is widely used to evaluate and classify obesity, it mainly represents general adiposity and can be confounded by excessive muscle mass or frailty. Guidelines from the American Diabetes Association state that in addition to weight and BMI, clinicians should consider weight distribution (including predisposition for central/visceral adipose deposition) and weight gain pattern and trajectory because these can help guide risk stratification and treatment options.

Increasingly, evidence supports visceral adiposity, or abdominal obesity, as a marker of cardiovascular risk. Abdominal obesity has been shown to be a strong independent predictor of mortality. On its own, BMI is an insufficient biomarker of abdominal obesity. Not all individuals with obesity have a central distribution of their weight; some individuals may have central obesity without meeting the criteria for the BMI definition of obesity. This can lead to misclassification and underdiagnosis of health risks in clinical practice. Consequently, numerous organizations and expert panels have recommended that waist circumference be measured along with BMI, specifically when the BMI < 35. Measurement of both BMI and waist circumference provides valuable opportunities to counsel patients regarding their risk for cardiovascular disease and other complications of obesity. Waist-to-hip ratio has also been shown to be a stronger predictor for mortality compared with BMI; however, it is rarely measured in clinical practice.

Although rarely performed outside of research settings, measurement of epicardial and pericardial fat via CT is also emerging as a potentially useful approach for informing predictive and precision medicine strategies. Recently, the Jackson Heart Study showed pericardial and visceral fat volumes were associated with incident heart failure, particularly heart failure with preserved ejection fraction, and all-cause mortality among Black participants even after adjusting for age, sex, education, and smoking status. Another recent study showed an increased risk of heart failure, particularly heart failure with preserved ejection fraction, among men and women with high pericardial fat volume. The Multi-Ethnic Study of Atherosclerosis showed that pericardial fat was associated with a higher risk of all-cause cardiovascular disease, hard atherosclerotic cardiovascular disease, and heart failure. Epicardial fat is directly correlated with BMI, visceral adiposity, and waist circumference.

Best practices for the management of obesity begin with recognizing and treating it as a complex chronic disease rather than the result of an individual's lifestyle choices. According to a 2020 joint international consensus statement for ending the stigma of obesity, the assumption that choosing to eat less and/or exercise more can entirely prevent or reverse obesity is contradicted by a definitive body of biological and clinical evidence that shows obesity results primarily from a complex combination of genetic, epigenetic, and environmental factors. When diagnosing patients with obesity, it may be helpful for clinicians to acknowledge that the term obesity is often perceived as an undesirable term because it has been associated with stigma but that it is in fact a clinical diagnosis, not a judgement. Many patients prefer the neutral term unhealthy weight over obesity.

As with other chronic diseases, individualized treatment and long-term support along with shared decision-making are essential for optimizing outcomes. Key components of obesity management include diet, exercise, and behavioral modification. In addition, an increasing array of pharmacologic therapies are also showing unprecedented efficacy for weight management, including several drugs that are also approved for the management of type 2 diabetes. In particular, the glucagonlike peptide 1 (GLP-1) agonists, semaglutide and liraglutide, and the novel glucose-dependent insulinotropic polypeptide (GIP)–GLP-1 receptor agonist, tirzepatide have been associated with significant weight loss. Semaglutide and liraglutide have been US Food and Drug Administration (FDA)–approved for chronic weight management and tirzepatide was granted fast track designation for the treatment of obesity by the FDA in October 2022. These drugs may also help to prevent the progression of prediabetes to diabetes. For individuals with severe obesity, metabolic and bariatric surgery is an effective treatment option that is associated with clinically significant and relatively sustained weight reduction in addition to significant amelioration of related complications.

This patient's clinical presentation of weight gain and associated symptoms are most closely related to a diagnosis of obesity. In addition, her laboratory findings are consistent with common obesity complications, including prediabetes and dyslipidemia, and her blood pressure is borderline high. 

Obesity is a chronic, multifactorial disease with a complex pathogenesis comprising of genetic, biological, psychosocial, socioeconomic, and environmental factors. It is a heterogeneous disease characterized by a dysfunction of the normal pathways and mechanisms that are involved in body fat regulation (often referred to as weight regulation), which may lead to variable presentation and complications. According to the US Centers for Disease Control and Prevention, the highest age-adjusted prevalence of obesity is seen in non-Hispanic Black adults (49.9%), followed by Hispanic adults (45.6%), non-Hispanic White adults (41.4%), and non-Hispanic Asian adults (16.1%).

Epidemiologic studies have defined obesity as a BMI > 30, which is then subclassified into class 1 (BMI of 30-34.9), class 2 (BMI of 35-39.9), or class 3 (BMI ≥ 40) obesity. Though BMI is widely used to evaluate and classify obesity, it mainly represents general adiposity and can be confounded by excessive muscle mass or frailty. Guidelines from the American Diabetes Association state that in addition to weight and BMI, clinicians should consider weight distribution (including predisposition for central/visceral adipose deposition) and weight gain pattern and trajectory because these can help guide risk stratification and treatment options.

Increasingly, evidence supports visceral adiposity, or abdominal obesity, as a marker of cardiovascular risk. Abdominal obesity has been shown to be a strong independent predictor of mortality. On its own, BMI is an insufficient biomarker of abdominal obesity. Not all individuals with obesity have a central distribution of their weight; some individuals may have central obesity without meeting the criteria for the BMI definition of obesity. This can lead to misclassification and underdiagnosis of health risks in clinical practice. Consequently, numerous organizations and expert panels have recommended that waist circumference be measured along with BMI, specifically when the BMI < 35. Measurement of both BMI and waist circumference provides valuable opportunities to counsel patients regarding their risk for cardiovascular disease and other complications of obesity. Waist-to-hip ratio has also been shown to be a stronger predictor for mortality compared with BMI; however, it is rarely measured in clinical practice.

Although rarely performed outside of research settings, measurement of epicardial and pericardial fat via CT is also emerging as a potentially useful approach for informing predictive and precision medicine strategies. Recently, the Jackson Heart Study showed pericardial and visceral fat volumes were associated with incident heart failure, particularly heart failure with preserved ejection fraction, and all-cause mortality among Black participants even after adjusting for age, sex, education, and smoking status. Another recent study showed an increased risk of heart failure, particularly heart failure with preserved ejection fraction, among men and women with high pericardial fat volume. The Multi-Ethnic Study of Atherosclerosis showed that pericardial fat was associated with a higher risk of all-cause cardiovascular disease, hard atherosclerotic cardiovascular disease, and heart failure. Epicardial fat is directly correlated with BMI, visceral adiposity, and waist circumference.

Best practices for the management of obesity begin with recognizing and treating it as a complex chronic disease rather than the result of an individual's lifestyle choices. According to a 2020 joint international consensus statement for ending the stigma of obesity, the assumption that choosing to eat less and/or exercise more can entirely prevent or reverse obesity is contradicted by a definitive body of biological and clinical evidence that shows obesity results primarily from a complex combination of genetic, epigenetic, and environmental factors. When diagnosing patients with obesity, it may be helpful for clinicians to acknowledge that the term obesity is often perceived as an undesirable term because it has been associated with stigma but that it is in fact a clinical diagnosis, not a judgement. Many patients prefer the neutral term unhealthy weight over obesity.

As with other chronic diseases, individualized treatment and long-term support along with shared decision-making are essential for optimizing outcomes. Key components of obesity management include diet, exercise, and behavioral modification. In addition, an increasing array of pharmacologic therapies are also showing unprecedented efficacy for weight management, including several drugs that are also approved for the management of type 2 diabetes. In particular, the glucagonlike peptide 1 (GLP-1) agonists, semaglutide and liraglutide, and the novel glucose-dependent insulinotropic polypeptide (GIP)–GLP-1 receptor agonist, tirzepatide have been associated with significant weight loss. Semaglutide and liraglutide have been US Food and Drug Administration (FDA)–approved for chronic weight management and tirzepatide was granted fast track designation for the treatment of obesity by the FDA in October 2022. These drugs may also help to prevent the progression of prediabetes to diabetes. For individuals with severe obesity, metabolic and bariatric surgery is an effective treatment option that is associated with clinically significant and relatively sustained weight reduction in addition to significant amelioration of related complications.

When I hear about a new drug for inflammatory skin disease that has a novel target, the first thing I do is Google what happens when you have a deficiency in that pathway. For OX40, the first thing that comes up is "inherited human OX40 deficiency underlying classic Kaposi sarcoma of childhood."¹ That doesn't make this target seem appealing to me. While I might use a new drug targeting this pathway if other options fail, drugs targeting this pathway would not be my first choice, even if clinical trial safety data looked good. Clinical trials are powered to assess efficacy and common safety issues but tend not to be large enough to fully characterize rare risks.

Black box warnings on topical calcineurin inhibitors seem dumb to me. I think black box warnings on topical calcineurin inhibitors would be truly ridiculous, even laughable, except that laughing is not appropriate because these misguided warnings may be hurting our patients. These black box warnings on topical calcineurin inhibitors may exemplify the limitations of governmental bureaucracies. There doesn't seem to be a strong rationale for why these black box warnings were placed on topical calcineurin inhibitors initially. Why regulators haven't removed these black box warnings since then is baffling, as topical calcineurin inhibitors are considerably safer for patients than the alternative, topical corticosteroids. We have good evidence that topical calcineurin inhibitors do not cause cancer in our patients. The continued presence of black box warnings on these products may undermine the credibility of FDA-mandated black box warnings on other products.

Hedderson and colleagues state, in a study of cardiovascular events and atopic dermatitis, "VTE [venous thromboembolism] and DVT [deep vein thrombosis] IRs [incidence rates] were markedly higher in this study than have been observed in the general US adult population (VTE: 2.0 [current study] vs. 1.1; DVT: 1.6 [current study] vs. 0.66 per 1000 person-years." I think that's misleading. The difference of only 1 in 1000 doesn't seem like a markedly higher rate to me and it's also unlikely to be clinically meaningful. Even if there is some increased relative risk of some type of cardiovascular event, even if the rate is doubled, that doesn't mean we need to screen or intervene. We need to be mindful of the absolute risks and not be moved by relative risks. We need to see cost-effectiveness studies showing that an intervention is valuable before we conclude that we should be doing some screening or intervention to chase down and increase the relative risk for some potential adverse event.

The US Preventive Services Task Force (USPSTF) recently released draft recommendations on screening for tuberculosis (TB).¹ The USPSTF continues to recommend screening for latent TB infection (LTBI) in those at high risk.

Why is this important? Up to one-quarter of the world’s population has been infected with TB, according to World Health Organization (WHO) estimates. In 2021, active TB was diagnosed in 10.6 million people, and it caused 1.6 million deaths.² Worldwide, TB is still a major cause of mortality: It is the 13th leading cause of death and is the leading cause of infectious disease mortality in non-COVID years.

Although the rate of active TB in the United States has been declining for decades (from 30.7/100,000 in 1960 to 2.4/100,000 in 2021), 7882 cases were reported in 2021, and an estimated 13 million people in the United States have LTBI.³ If not treated, 5% to 10% of LTBI cases will progress to active TB. This risk is higher in those with certain medical conditions.³ People born outside the United States currently account for 71.4% of reported TB cases in the United States.³

To reduce the morbidity and mortality of TB, the Centers for Disease Control and Prevention (CDC), WHO, and USPSTF all recommend screening for and treating LTBI. An effective approach to TB control also includes early detection and completion of treatment for active TB, as well as testing contacts of active TB cases.

Who should be screened? Those at high risk for LTBI include those who were born in, or who have resided in, countries with high rates of TB (eg, Latin America, the Caribbean, Africa, Asia, Eastern Europe, and Russia); those who have lived in a correctional facility or homeless shelter; household and other close contacts of active TB cases; and health care workers who provide care to patients with TB.

Some chronic medical conditions can increase risk for progression to active TB in those with LTBI. Patients who should be tested for LTBI as part of their routine care include those who are HIV positive; are receiving immunosuppressive therapy (chemotherapy, biological immune suppressants); have received an organ transplant; have silicosis; use illicit injected drugs; and/or have had a gastrectomy or jejunoileal bypass.

In addition, local communities may have populations or geographic regions in which TB rates are high. Family physicians can obtain this information from their state or local health departments.

There are 2 screening tests for LTBI: TB blood tests (interferon-gamma release assays [IGRAs]) and the Mantoux tuberculin skin test (TST). Two TB blood tests are available in the United States: QuantiFERON-TB Gold Plus (QFT-Plus) and T-SPOT.TB test (T-Spot).

There are advantages and disadvantages to both types of tests. A TST requires accurate administration and interpretation and 2 clinic visits, 48 to 72 hours apart. The cutoff on a positive test (5, 10, or 15 mm) depends on the patient’s age and risk.⁴ An IGRA should be processed within 8 to 32 hours and is more expensive. However, a major advantage is that it is more specific, because it is unaffected by previous vaccination with bacille Calmette-Guérin or by most nontuberculous mycobacteria infections.

To rule out active TB ... If a TB screening test is positive, the recommended work-up is to ask about TB symptoms and perform a chest x-ray to rule out active pulmonary TB. Sputum collection for acid-fast smear and culture should be ordered for anyone with a suspicious chest x-ray, respiratory symptoms consistent with TB, or HIV infection.

Treatment for LTBI markedly reduces the risk for active TB. There are 4 options:

• Isoniazid (INH) plus rifapentine (RPT) once per week for 3 months.
• Rifampin (RIF) daily for 4 months.
• INH plus RIF daily for 3 months.
• INH daily for 6 or 9 months.

Details about the variables to consider in choosing a regimen are described on the CDC website.^4,5

Know your resources. Local and state public health departments should have TB control programs and are sources of information on TB diagnosis and treatment; they also can assist with follow-up of TB contacts.⁶ Although LTBI is a reportable condition only in young children, any suspicion of community spread of active TB should be reported to the public health department.

Two new papers published recently provide evidence of the efficacy and safety of bimekizumab in psoriatic arthritis (PsA). Bimekizumab is a novel bispecific monoclonal antibody targeting interleukin (IL)-17A and IL-17F and is already approved for the treatment of chronic plaque psoriasis. McInnes and colleagues reported the results of the phase 3 BE OPTIMAL study, which included 852 patients with active PsA who were naive to biologic disease-modifying antirheumatic drugs (bDMARD) and were randomly assigned to receive bimekizumab, placebo, or adalimumab. At week 16, a significantly higher proportion of patients receiving bimekizumab vs placebo achieved ≥ 50% improvement in American College of Rheumatology response (ACR50; 44% vs 10%; odds ratio [OR] 7.1; P < .0001). Compared with placebo, significant improvements were also noted in psoriasis, enthesitis, and dactylitis in the bimekizumab group and there was less progression of radiographic damage.

Bimekizumab was also demonstrated to be beneficial in PsA patients with inadequate response or intolerance to tumor necrosis factor inhibitors (TNFi). In the phase 3 BE COMPLETE study, which included 400 patients with active PsA and previous inadequate response or intolerance to TNFi, patients were randomly assigned to receive 160 mg subcutaneous bimekizumab every 4 weeks or placebo. Merola and colleagues reported that at week 16, a significantly higher proportion of patients receiving bimekizumab vs placebo achieved ACR50 response (43% vs 7%; OR 11.1; P < .0001). Thus, bimekizumab is a welcome addition to the treatment portfolio we have for PsA. In regard to side effects of special concern when inhibiting IL-17, bimekizumab was associated with higher risk for oral and genital candidiasis, occurring in 4% of the treated patients within 16 weeks in the two studies; however, no cases of systemic fungal infections occurred. The incidence of inflammatory bowel disease was also very low, but head-to-head studies against other available agents would be required to help rheumatologists decide the place of bimekizumab in PsA management.

A common clinical question is whether axial PsA is similar to ankylosing spondylitis (AS) with psoriasis. Assuming that it is, clinicians have used treatments approved for AS for managing axial PsA. Recent studies have questioned this assumption, however. Michelena and colleagues conducted a cross-sectional study that included 109 patients with axial PsA and 127 patients with AS and psoriasis from the REGISPONSER registry. Compared with patients with AS and psoriasis, patients with human leukocyte antigen (HLA)-B27–negative axial PsA had less inflammatory pain (P = .002), anterior uveitis (P = .014), and structural damage (P < .001), along with a higher prevalence of nail disease (P = .009). Patients with HLA-B27–positive axial PsA vs AS and psoriasis were similar but had less structural damage to the spine (P < .001). Thus, there seem to be significant clinical and genetic differences between these two diseases that require further investigation. Lack of an accepted definition of axial PsA, however, is a hindrance to multiple high-quality genetic, clinical, and interventional studies comparing axial PsA and AS with psoriasis.

Observational studies have recognized the clinical and familial association between psoriatic disease and Crohn's disease (CD), but such cross-sectional or retrospective studies cannot identify causal relationships. Mendelian randomization is a method used to identify causal relationships. Using this method, Sun and colleagues demonstrated that PsA was associated with a 31.9% increased risk for CD (P < .001) and genetically predicted CD was linked to a 44.8% higher risk for PsA (P = .001). No such association was found with ulcerative colitis. Thus, there is a bidirectional causal relationship between the two diseases. Patients with PsA should be evaluated for symptoms of CD, and those with CD for psoriatic disease, to facilitate early diagnosis and better long-term outcomes.

Two new papers published recently provide evidence of the efficacy and safety of bimekizumab in psoriatic arthritis (PsA). Bimekizumab is a novel bispecific monoclonal antibody targeting interleukin (IL)-17A and IL-17F and is already approved for the treatment of chronic plaque psoriasis. McInnes and colleagues reported the results of the phase 3 BE OPTIMAL study, which included 852 patients with active PsA who were naive to biologic disease-modifying antirheumatic drugs (bDMARD) and were randomly assigned to receive bimekizumab, placebo, or adalimumab. At week 16, a significantly higher proportion of patients receiving bimekizumab vs placebo achieved ≥ 50% improvement in American College of Rheumatology response (ACR50; 44% vs 10%; odds ratio [OR] 7.1; P < .0001). Compared with placebo, significant improvements were also noted in psoriasis, enthesitis, and dactylitis in the bimekizumab group and there was less progression of radiographic damage.

Bimekizumab was also demonstrated to be beneficial in PsA patients with inadequate response or intolerance to tumor necrosis factor inhibitors (TNFi). In the phase 3 BE COMPLETE study, which included 400 patients with active PsA and previous inadequate response or intolerance to TNFi, patients were randomly assigned to receive 160 mg subcutaneous bimekizumab every 4 weeks or placebo. Merola and colleagues reported that at week 16, a significantly higher proportion of patients receiving bimekizumab vs placebo achieved ACR50 response (43% vs 7%; OR 11.1; P < .0001). Thus, bimekizumab is a welcome addition to the treatment portfolio we have for PsA.

January's theme is migraine triggers. We'll take a look at three recent studies that have tried to better determine the nature of specific triggers for headache.

One of the most common and reportedly consistent migraine triggers is exposure to alcohol, and the International Classification of Headache Disorders (ICHD-3) includes alcohol-induced headache as a secondary headache. Little is known regarding the association between migraine and alcohol. Vives-Mestres and colleagues investigated the alcohol intake of people using a digital health diary for headache. They specifically looked at the 48 hours preceding a migraine attack and whether alcohol was consumed, and also the number of beverages consumed. This was further adjusted for sex, age, and average weekly alcohol intake.

The N1-Headache Tracker is a digital headache diary that patients use to track their daily headache symptoms and inform them of potential migraine risk factors. Over a 90-day period, this study followed patients that did not meet the criteria for a diagnosis of chronic migraine. They also reported on their intake to the platform that they regularly consume alcohol. Of note, persons who never tracked alcohol consumption were excluded from this study. On intake to the platform, alcohol exposure was characterized both as whether daily consumption of alcohol was occurring and as the total daily number of alcoholic beverages.

The primary outcome of this study was migraine attack 1 day after alcohol consumption. Participants were specifically asked if their headaches were diagnosed as migraine by a physician. Migraine attack onset was considered binary, and a logistic model was used to estimate the probability of having a migraine attack on any given day with the association of alcohol intake for up to 48 hours prior to that day.

A total of 487 people with migraine were included in this trial and they collectively contributed over 43,000 diary days; almost 6000 were first days of a migraine attack. Overall alcohol consumption was not considered high and was noted to vary between groups; people with lower frequency migraine tended to have higher rates of alcohol intake. No significant correlation was observed between the presence of migraine attacks within 48 hours after alcohol consumption. This did not vary among different probability models; a population-level model showed that the probability of a migraine attack 2 days after alcohol intake was 25% lower than the probability of an attack with no alcohol consumption. This was also true after adjustment for age, sex, and average number of alcoholic beverages per week.

The association between migraine and alcohol is complicated, and the concept of migraine triggers in general is very complex. Although over 70% of people with migraine say that they have a consistent trigger, and alcohol is consistently at the top of the list of those reported triggers, there does not appear to be a direct correlation between migraine and alcohol exposure. The greatest caveat of this study is the fact that people with chronic migraine were excluded. Further research should specifically investigate triggers such as alcohol in this population.

The use of proton pump inhibitors (PPI) has been shown in previous studies over the past few years to be associated with a number of neurologic events and risks, including impaired hearing, vision, and memory, as well as migraine occurrence. The specifics of this association are not well known — specifically, whether the duration of use is the main factor, or whether it is acute exposure to a PPI medication that is a trigger. Kang and colleagues reviewed data in the Korean national database and developed a case-control model to study this association specifically.

The migraine and control groups were equally matched: They had the same demographics, smoking status, alcohol consumption, blood pressure range, fasting glucose, and total cholesterol. Past and current PPI use and comparisons of migraine occurrence were further differentiated among patients who were exposed to PPI medications for < 30 days, 30-365 days, and > 365 days.

The use of PPI treatments was noted to be linked to increased migraine regardless of duration, and regardless of the acute presence of the PPI. Even a history of prior PPI use was noted to increase the odds ratio of migraine development. This was significant among all subgroups, independent of age, sex, and other comorbidities. There was no difference in the presence of aura associated with migraine.

As we noted above, the concept of migraine triggers is overall poorly understood. This is even more the case when it comes to historical exposures. Although the use of PPI medications appears to be associated with the occurrence of migraine in this population, these medications are necessary in many instances, including in patients with severe gastritis and gastroesophageal reflux refractory to diet changes. It remains to be seen precisely how PPI medications would potentially lead to a higher incidence of migraine.

Among many of the triggers discussed, specific foods are commonly thought to be associated with migraine. Although there is scant evidence for a specific diet to improve migraine frequency, many patients are very interested in potential dietary changes that may help them. Prior studies and reviews have looked at gluten-free, dairy-free, low-carbohydrate, low-tyramine, and elimination diets — all of which were not associated with a significant improvement in migraine frequency or severity. Bakıran and colleagues sought to investigate an antioxidant-rich diet that included polyphenols and carotenoids — substances that may improve systemic inflammation, glucose metabolism, and oxidative stress.

Phytochemical-rich foods include fruits and vegetables (excluding potatoes) as well as nuts, whole grains, pulses, and olive oil. The phytochemical index is a tool used by dietitians and nutritionists to assess the phytochemical content in a diet.

A total of 90 patients who had a diagnosis of episodic migraine by a neurologist were enrolled. Individuals were excluded if they had a body mass index > 40 or < 18 or had other significant chronic comorbidities, such as hypertension, diabetes, hepatic or renal disease, or other neurologic conditions. Participants filled out a headache diary over 3 months; the Migraine Disability Assessment (MIDAS) questionnaire was also followed in order to assess migraine-related disability. Diet quality was cataloged as per patient records; patients also filled out a 3-day nonconsecutive food diary. This information was added to a food software program that calculated specific nutrients, including the phytochemical index.

Participants were divided into groups with good diet quality and poor diet quality based on their phytochemical index. No differences were seen in migraine frequency or disability between these groups, although mean attack duration was lower in those with poor diet quality. Severity was noted to be higher in those with poor diet quality; 75% of participants with poor diet quality experienced severe attacks.

Overall, the results of this study are very mixed. Participants on the recommended high phytochemical diet were seen to have lower severity of migraine but a prolonged duration of attack. There also was no correlation between this diet and either frequency or disability. This was a small study, and further research should focus on this among other diet changes that have the possibility to improve the quality of life of people with migraine.

The Diagnosis: Atypical Mycobacterial Infection

The history of rapid growth followed by shrinkage as well as the craterlike clinical appearance of our patient’s lesion were suspicious for the keratoacanthoma variant of squamous cell carcinoma (SCC). Periodic acid–Schiff green staining was negative for fungal or bacterial organisms, and the biopsy findings of keratinocyte atypia and irregular epidermal proliferation seemed to confirm our suspicion for well-differentiated SCC (Figure 1). Our patient subsequently was scheduled for Mohs micrographic surgery. Fortunately, a sample of tissue had been sent for panculture—bacterial, fungal, and mycobacterial—to rule out infectious etiologies, given the history of possible traumatic inoculation, and returned positive for Mycobacterium marinum infection prior to the surgery. Mohs surgery was canceled, and he was referred to an infectious disease specialist who started antibiotic treatment with azithromycin, ethambutol, and rifabutin. After 1 month of treatment the lesion substantially improved (Figure 2), further supporting the diagnosis of M marinum infection over SCC.

The differential diagnosis also included sporotrichosis, leishmaniasis, and chromoblastomycosis. Sporotrichosis lesions typically develop as multiple nodules and ulcers along a path of lymphatic drainage and can exhibit asteroid bodies and cigar-shaped yeast forms on histology. Chromoblastomycosis may display pseudoepitheliomatous hyperplasia and granulomatous inflammation; however, pathognomonic pigmented Medlar bodies also likely would be present.¹ Leishmaniasis has a wide variety of presentations; however, it typically occurs in patients with exposure to endemic areas outside of the United States. Although leishmaniasis may demonstrate pseudoepitheliomatous hyperplasia, ulceration, and mixed inflammation on histology, it also likely would show amastigotes within dermal macrophages.²

Atypical mycobacterial infections initially may be misdiagnosed as SCC due to their tendency to induce irregular acanthosis in the form of pseudoepitheliomatous hyperplasia as well as mild keratinocyte atypia secondary to inflammation.^3,4 Our case is unique because it occurred with M marinum infection specifically. The histopathologic findings of M marinum infections are variable and may additionally include granulomas, most commonly suppurative; intraepithelial abscesses; small vessel proliferation; dermal fibrosis; multinucleated giant cells; and transepidermal elimination.^4,5 Periodic acid–Schiff, Ziehl-Neelsen (acid-fast bacilli), and Fite staining may be used to distinguish M marinum infection from SCC but have low sensitivities (approximately 30%). Culture remains the most reliable test, with a sensitivity of nearly 80%.^5-7 In our patient, a Periodic acid–Schiff stain was obtained prior to receiving culture results, and acid-fast bacilli and Fite staining were added after the culture returned positive; however, all 3 stains failed to highlight any mycobacteria.

The primary risk factor for infection with M marinum is contact with aquatic environments or marine animals, and most cases involve the fingers or the hand.⁶ After we reached the diagnosis and further discussed the patient’s history, he recalled fishing for and cleaning raw shrimp around the time that he had a splinter. The Infectious Diseases Society of America recommends a treatment course extending 1 to 2 months after clinical symptoms resolve with ethambutol in addition to clarithromycin or azithromycin.⁸ If the infection is near a joint, rifampin should be empirically added to account for a potentially deeper infection. Imaging should be obtained to evaluate for joint space involvement, with magnetic resonance imaging being the preferred modality. If joint space involvement is confirmed, surgical debridement is indicated. Surgical debridement also is indicated for infections that fail to respond to antibiotic therapy.⁸

This case highlights M marinum infection as a potential mimicker of SCC, particularly if the biopsy is relatively superficial, as often occurs when obtained via the common shave technique. The distinction is critical, as M marinum infection is highly treatable and inappropriate surgery on the typical hand and finger locations may subject patients to substantial morbidity, such as the need for a skin graft, reduced mobility from scarring, or risk for serious wound infection.⁹ For superficial biopsies of an atypical squamous process, pathologists also may consider routinely recommending tissue culture, especially for hand and finger locations or when a history of local trauma is reported, instead of recommending complete excision or repeat biopsy alone.

Sporotrichosis lesions typically develop as multiple nodules and ulcers along a path of lymphatic drainage and can exhibit asteroid bodies and cigar-shaped yeast forms on histology. Chromoblastomycosis may display pseudoepitheliomatous hyperplasia and granulomatous inflammation; however, pathognomonic pigmented Medlar bodies also likely would be present.¹ Leishmaniasis has a wide variety of presentations; however, it typically occurs in patients with exposure to endemic areas outside of the United States. Although leishmaniasis may demonstrate pseudoepitheliomatous hyperplasia, ulceration, and mixed inflammation on histology, it also likely would show amastigotes within dermal macrophages.²

Atypical mycobacterial infections initially may be misdiagnosed as SCC due to their tendency to induce irregular acanthosis in the form of pseudoepitheliomatous hyperplasia as well as mild keratinocyte atypia secondary to inflammation.^3,4 Our case is unique because it occurred with M marinum infection specifically. The histopathologic findings of M marinum infections are variable and may additionally include granulomas, most commonly suppurative; intraepithelial abscesses; small vessel proliferation; dermal fibrosis; multinucleated giant cells; and transepidermal elimination.^4,5 Periodic acid–Schiff, Ziehl-Neelsen (acid-fast bacilli), and Fite staining may be used to distinguish M marinum infection from SCC but have low sensitivities (approximately 30%). Culture remains the most reliable test, with a sensitivity of nearly 80%.^5-7 In our patient, a Periodic acid–Schiff stain was obtained prior to receiving culture results, and acid-fast bacilli and Fite staining were added after the culture returned positive; however, all 3 stains failed to highlight any mycobacteria.

The primary risk factor for infection with M marinum is contact with aquatic environments or marine animals, and most cases involve the fingers or the hand.⁶ After we reached the diagnosis and further discussed the patient’s history, he recalled fishing for and cleaning raw shrimp around the time that he had a splinter. The Infectious Diseases Society of America recommends a treatment course extending 1 to 2 months after clinical symptoms resolve with ethambutol in addition to clarithromycin or azithromycin.⁸ If the infection is near a joint, rifampin should be empirically added to account for a potentially deeper infection. Imaging should be obtained to evaluate for joint space involvement, with magnetic resonance imaging being the preferred modality. If joint space involvement is confirmed, surgical debridement is indicated. Surgical debridement also is indicated for infections that fail to respond to antibiotic therapy.⁸

This case highlights M marinum infection as a potential mimicker of SCC, particularly if the biopsy is relatively superficial, as often occurs when obtained via the common shave technique. The distinction is critical, as M marinum infection is highly treatable and inappropriate surgery on the typical hand and finger locations may subject patients to substantial morbidity, such as the need for a skin graft, reduced mobility from scarring, or risk for serious wound infection.⁹ For superficial biopsies of an atypical squamous process, pathologists also may consider routinely recommending tissue culture, especially for hand and finger locations or when a history of local trauma is reported, instead of recommending complete excision or repeat biopsy alone.

The Diagnosis: Atypical Mycobacterial Infection

The history of rapid growth followed by shrinkage as well as the craterlike clinical appearance of our patient’s lesion were suspicious for the keratoacanthoma variant of squamous cell carcinoma (SCC). Periodic acid–Schiff green staining was negative for fungal or bacterial organisms, and the biopsy findings of keratinocyte atypia and irregular epidermal proliferation seemed to confirm our suspicion for well-differentiated SCC (Figure 1). Our patient subsequently was scheduled for Mohs micrographic surgery. Fortunately, a sample of tissue had been sent for panculture—bacterial, fungal, and mycobacterial—to rule out infectious etiologies, given the history of possible traumatic inoculation, and returned positive for Mycobacterium marinum infection prior to the surgery. Mohs surgery was canceled, and he was referred to an infectious disease specialist who started antibiotic treatment with azithromycin, ethambutol, and rifabutin. After 1 month of treatment the lesion substantially improved (Figure 2), further supporting the diagnosis of M marinum infection over SCC.
