Successful Treatment of Atopic Dermatitis with Dupilumab in a Patient with Non-Hodgkin's Lymphoma

Treatment of Severe Atopic Dermatitis with Dupilumab in Patients with Advanced Cancer

Atopic dermatitis is a chronic inflammatory intensively pruritic skin disease. Patients with moderate-to-severe atopic dermatitis or with difficult-to-treat areas are candidates for systemic therapy, especially when topical therapy is inadequate. Currently, we have available not only conventional immunosuppressive systemic therapy, but also targeted biological therapy, which has shown a remarkable reduction in clinical severity with a good safety profile. Dupilumab has been approved to treat moderate-to-severe atopic dermatitis. Even though the therapy has been available for more than 3 years, there are still limited data regarding the treatment of patients with concomitant cancer. Previous immunosuppressive treatment for atopic dermatitis, such as cyclosporine or azathioprine, poses a safety risk for patients with malignant disease. We present a case series of three patients with advanced cancer and severe atopic dermatitis treated with dupilumab for an average of 17 months with a great response toward atopic dermatitis without cancer recurrence. One patient had colorectal cancer' the second and the third both had cancer duplicity-colorectal and kidney cancer and penile squamous cell carcinoma with prostate cancer. Our cases suggest that dupilumab can safely control atopic dermatitis in patients with advanced cancer.

Dupilumab for the treatment of prurigo nodularis: A systematic review

Background

Conventional treatment techniques have limited efficacy and more side effects in the treatment of prurigo nodularis. The better alternative treatment option for better outcomes of the disease is dupilumab.

Objective

The objective of this study was to systematically review dupilumab-related treatment outcomes in prurigo nodularis.

Methods

Several databases like Embase, PubMed, Web of Science, and Cochrane library were searched for data acquisition on October 8, 2022. Based on Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, 24 publications were included in this study.

Results

After 4,12,16 and more than 16 weeks of dupilumab treatment, 8.3% (n=5/60), 34.4% (n=11/32), 3.6% (n=2/56), and 45.3% (n=29/64) of patients had complete remission, respectively. In addition, 85.0% (n=51/60), 59.4% (n=19/32), 83.9% (n=47/56), and 43.8% (n=28/64) had partial remission, respectively. Moreover, 6.7% (n=4/60), 6.3% (n=2/32), 12.5% (n=7/56), and 10.9% (n=7/64) showed no remission, respectively, and significant reduction of numeric rating scale itch intensity (from 9.0 to 4.9, 2.1, 2.8, 0.9) was attained. There were no serious adverse events observed during treatment, but the most common event observed was conjunctivitis (12.6%, n=15/119).

Conclusions

Dupilumab has definite effectiveness and safety in prurigo nodularis treatment.

Dupilumab in the Treatment of Cheilitis in Atopic Dermatitis Patients

Background/Objectives

The lip is a unique tissue type that acts as a “barrier” to the mouth and receives many external stimuli. It is also a common symptom in atopic dermatitis. Dupilumab was the first targeted biological drug approved for the treatment of moderate-to-severe atopic dermatitis (AD). There is no real-world clinical data on the use of dupilumab in patients with AD and cheilitis. This retrospective study compared the improvement in skin lesions in AD patients with cheilitis after dupilumab treatment and evaluated the improvement in cheilitis.

Methods

This is a retrospective case series. We investigated patients with AD treated with dupilumab in our department from September 2020 to May 2022, including those with cheilitis. Demographic information such as age, sex, AD or other atopy history, and the anatomical site of dermatitis was collected. Disease severity was assessed using the eczema area and severity index score (EASI), body surface area (BSA), and severity assessment of cheilitis (the cheilitis symptom score) at baseline and after 16 weeks.

Results

We reviewed 96 patients treated with dupilumab for AD, and including the 10 patients with cheilitis (10.4%). All patients demonstrated significant improvement in skin lesions, and lip symptoms improved in seven patients. Among AD patients with improved cheilitis, the average reduction in EASI was 35.0% for BSA (34.9%) and the cheilitis symptom score was 29.9% at week 8. At week 16, compared with the baseline score, the improvement in cheilitis symptom scores was 58.1%, EASI was 60.8%, and BSA was 56.2%, respectively.

Conclusion

Effective treatment of both the skin and cheilitis was achieved with dupilumab. The improvement in cheilitis involvement was slower than that in skin lesions. This case series confirms that dupilumab could be a valuable approach for treating patients with atopic dermatitis-associated lip involvement.

Atopic Dermatitis with Multiple Comorbidities Treated with Dupilumab. A Case Report and Review of the Literature Regarding the Safety of Dupilumab

Dupilumab is the only available biological treatment for moderate-to-severe atopic dermatitis (AD). Even so, limited clinical data regarding its safety profile are available. Interactions with other drugs and the adverse effects of Dupilumab on patients with multiple comorbidities, such as chronic heart disease, diabetes, chronic kidney disease, etc., are not known yet. Moreover, there have been described cases of cutaneous lymphomas induced by Dupilumab. Therefore, the clinician that wants to start treatment for moderate-to-severe atopic dermatitis, which does not respond to conventional drugs, might be reluctant to choose biologic agents such as Dupilumab. In this paper, we reported a case of severe atopic dermatitis with multiple comorbidities in which the patient was successfully treated with Dupilumab despite numerous underlying conditions. We also conducted a review of the current literature on the safety profile of Dupilumab in special categories of patients with comorbidities, such as heart, kidney, and liver disease, oncologic conditions, and during pregnancy.

Dupilumab for the treatment of adult atopic dermatitis in special populations

BACKGROUND

Special populations (SPs) involve people who require additional consideration in clinical research. Effectiveness of treatment or occurrence of side effects may be different in SPs with respect to not-SPs.

OBJECTIVES

To retrospectively compare the effectiveness and safety of dupilumab in AD treatment of SPs versus not-SPs.

METHODS

A 52-weeks retrospective study was performed enrolling patients with a diagnosis of moderate-to-severe AD undergoing treatment with dupilumab at labelled dosage. Patients were divided in Group A (SPs patients) and Group B (not-SPs patients). Disease severity was assessed using Eczema Area Severity Index (EASI), Pruritus-Numerical Rating Scale (P-NRS), and Dermatology Life Quality Index (DLQI) score at baseline and after 4 weeks (W4), W16, W24, and W52.

RESULTS

A total of 263 patients were enrolled and divided in Group A (25) and Group B (238). SPs included history of cancer, severe kidney failure, viral hepatitis, neurological diseases, acquired immunodeficiency syndrome, and transplanted patients. A statistically significant reduction of EASI, DLQI, and P-NRS was assessed in both groups at each follow-up visit (p < 0.0001), without significant differences between the groups. No differences were recorded for safety.

CONCLUSIONS

There are not significant differences between SPs and not-SPs as regards effectiveness and safety of dupilumab in AD management.
