Dupilumab for treatment of atopic dermatitis in patients living with HIV: a case series

Targeted Systemic Therapies for Adults with Atopic Dermatitis: Selecting from Biologics and JAK Inhibitors

Therapeutic options for people with moderate or severe atopic dermatitis refractory to topical therapy have rapidly expanded in recent years. These new targeted immunomodulatory agents-biologics and Janus kinase (JAK) inhibitors-have each demonstrated high levels of efficacy and acceptable safety in mostly placebo-controlled clinical trials for atopic dermatitis, but there is no universally applicable algorithm to help choose between them for a given patient. Hence, patients and physicians should utilize shared decision making, discussing efficacy, safety, mode of delivery, monitoring, costs, speed of onset, and other factors to reach individualized treatment decisions. In this review, we try to aid shared decision making by summarizing the efficacy, safety, and monitoring of biologics and oral JAK inhibitors for adults with atopic dermatitis. Network meta-analyses suggest that higher doses of abrocitinib and upadacitinib are more effective than biologics. They also show that, among biologics, dupilumab is likely more effective than tralokinumab and lebrikizumab. Biologics are generally considered safer than JAK inhibitors, although concerns about JAK inhibitors are mainly extrapolated from older generation JAK inhibitors used in higher-risk populations. We also outline evidence and considerations for choosing and using systemic immunomodulatory treatments for special populations including pregnant individuals, those with human immunodeficiency virus (HIV), hepatitis B and C, end stage kidney disease, and older adults.

Biologic Therapies in HIV/AIDS Patients with Inflammatory Diseases: A Systematic Review of the Literature

Biologic therapies have been increasingly developed and used for the treatment of severe inflammatory diseases. However, the safety and efficacy profile of biologic drugs in patients with HIV is not well established as this patient population is historically excluded from clinical trials. We review the available evidence of biologic use in people with HIV. We conducted a systematic review of the literature up to June 29, 2022 and included studies that treated patients with HIV who have inflammatory disease using biologic drugs. Clinical data regarding safety and efficacy were abstracted into tables. One hundred twelve studies were included, and 179 patients were included in our study. Nearly all classes of biologics drugs had a favorable safety profile with minimal or minor adverse events. Anti-CD-20 inhibitors and TNF-alpha inhibitors were associated with opportunistic infections. Transient increase in HIV viral load was noted with use of some agents such as TNF-alpha inhibitors. The quality of evidence is low, restricted to case reports and retrospective reviews. However, the safety profile of biologics observed in these patients with HIV was overall favorable.

The use of dupilumab in patients with HIV

BACKGROUND

The goal of this study was to complete the first Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) based systematic review of dupilumab use in patients living with human immunodeficiency virus (HIV).

METHODS

A systematic literature review was performed using PubMed, Google Scholar, Ovid MEDLINE, and Science Direct databases as well as an internal review using University of Virginia's electronic medical record system. All reports of dupilumab use in patients with confirmed HIV were included.

RESULTS

14 published cases comprising 23 patients were identified and included in the review. Additionally, four unpublished cases from our own institution were included for a final cohort of 27 patients. A total of 25 patients (96%) were observed to have a clinical response, defined as improvement or complete resolution of their cutaneous or asthmatic symptoms. In 100% of patients, viral load improved or did not change, and in 80% of patients, CD4 counts remained stable. Side effects occurred in 48% of patients but were self-limited.

DISCUSSION AND CONCLUSIONS

All reported cases indicate that dupilumab is safe in patients with HIV with stable CD4 counts and low viral loads. Most patients had significant improvement within 2 months of treatment with mild side effects.

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.
