The study by Merola and colleagues on the risk for venous thromboembolism (VTE) in patients with atopic dermatitis (AD) raises all kinds of interesting issues. To begin with, in this large, well-done, claim-based study, patients with AD were at higher risk for VTE than were control individuals without AD. However, after controlling for VTE risk factors (for example, steroid use), there was no meaningful difference in the VTE rate between those with and without AD. What matters when we treat patients, though, is the overall risk that people have; if people with AD tend to have more risk factors, we might need to be more concerned about VTE in AD patients.

But here's the thing: We should not be making clinical judgments on the basis of differences in relative risk; clinical decisions should be based on absolute risks. Should we worry about VTE risk when treating patients with AD? This paper did not focus on absolute risk, but we can get an idea of the absolute risk by looking at the data presented in the figures in the paper. The risk for VTE in patients without AD was about 1 in 400, whereas with AD the risk was about 1 in 300, even before controlling for risk factors. This rate is sufficiently low for both groups that it doesn't seem like this risk would affect whether we would use a drug that might be associated with some minimal or theoretical increased risk for VTE.

The bottom line is that the findings of this study are reassuring, at least to me.

I'm already convinced that dupilumab is a very safe treatment for our patients with AD. The study by Simpson and colleagues looked at data from a registry of patients followed in real-life practice. The 2-year study showed no new concerns for dupilumab treatment of AD. The most common adverse event was conjunctivitis, and that was seen in only 2.4% of the patients. Perhaps the most interesting finding was that 83% of the patients who started in the study were still on dupilumab treatment at the end of 2 years. Dupilumab has a good level of efficacy and safety such that the great majority of patients who start on it seem to do well.

Dupilumab is a highly effective, very safe treatment for AD. Rademikibart Is another interleukin-4 receptor alpha-chain blocker. Not surprisingly, rademikibart also seems to be an effective, safe treatment for AD (Silverberg et al). Rademikibart may serve as another option for AD, and I imagine that it could be used if a patient on dupilumab were to develop an anti-drug antibody and lose effectiveness.

The very interesting analysis by Silverberg and colleagues looks at a new way to compare the effectiveness of different drugs for AD. They use this new approach to compare upadacitinib and dupilumab. What they found, not surprisingly, was that upadacitinib was generally more effective for AD than dupilumab. I used to think I would never see anything more effective for AD than dupilumab, but, clearly, based on head-to-head trials, upadacitinib is more effective for AD than is dupilumab. But does that greater efficacy mean that we should use upadacitinib first? We need to consider safety, too. Dupilumab works well enough for the great majority of patients and is extremely safe. I think upadacitinib is a great choice for patients who did not respond to dupilumab and could also be considered for those patients who want to take the most effective treatment option.

Trimeche and colleagues' study of contact allergens in patients with AD may change how I practice. In this study, 60% of the AD patients had positive patch test results of which 71% were considered relevant. The most frequent allergens included textile dye mix (25%), nickel (20%), cobalt (13%), isothiazolinone (9%), quanterium-15 (4%), and balsam of Peru (4%). Two patients were allergic to corticosteroids. Avoidance of relevant allergens resulted in improvement. I need to warn my AD patients to be on the lookout for contact allergens that may be causing or exacerbating their skin disease.
