The Impact of Systemic Treatment of Atopic Dermatitis on Depressive Symptoms: A Prospective Clinical Cohort Study

Italian healthcare resource consumptions and direct costs of adults with atopic dermatitis before and after dupilumab treatment

BACKGROUND

Atopic dermatitis (AD) is a heterogeneous disease, associated with comorbidities, and high healthcare consumptions and costs. This study assessed the burden before and after treatment with dupilumab in adults with severe AD from 2018 to 2020, from the perspective of the Italian National Health Service (SSN).

METHODS

From Fondazione Ricerca e Salute's administrative healthcare database (~5 million inhabitants/year), adults treated with dupilumab from 09/01/2018 to 31/12/2020 (index date) and a five-year lookback were identified. Age, sex and comorbidities at baseline, concomitant drugs, overnight hospitalizations, outpatient specialist services and direct costs charged to the SSN one year before/after index date were assessed.

RESULTS

Of 337 adults treated with dupilumab (5.8x100,000 adult inhabitants/2019; 8.0x100,000/2020; 55% males; mean age 43±19), 68% (228/337) had ≥12-month follow-up available. Asthma was a common comorbidity (23% patients). Rates of patients treated with nearly all concomitant AD-related therapies reduced from 12 months before to 12 months after dupilumab treatment: antibacterials (from 59% to 50%), systemic corticosteroids (55% to 29%), antihistamines (54% to 38%) and cyclosporine (52% to 7%). A similar trend was observed among patients with asthma as comorbidity. Within 12 months before/after dupilumab, patients hospitalized halved from 14% to 7%, and patients receiving outpatient specialist care reduced from 72% to 65%. Annual mean direct total costs per patient treated with dupilumab charged to the SSN, net of dupilumab cost, were €1384 and €773, before and after dupilumab dispensation, respectively.

CONCLUSIONS

Before dupilumab, observed patients had higher healthcare resource consumptions and direct SSN costs than after dupilumab.

Patient and Caregiver Perspectives on the Relationship Between Atopic Dermatitis Symptoms and Mental Health

Background: Atopic Dermatitis (AD) patients have increased likelihood of developing depression and anxiety. The patient and caregiver's perceptions of the correlation of mental health (MH) and AD symptoms are not well understood. Objective: To evaluate patient-reported MH symptoms and their correlation with AD disease severity and understand patient-perceived associations of AD with impacts to their MH. Methods: Adult AD patients (18+ years) or caregivers of AD patients (8-17 years) were recruited to complete a survey about MH and their perception of its relationship with AD. Results: Of 1496 respondents, 954 met inclusion criteria and completed the survey. Respondents were primarily adults (83.3%) with moderate AD (31.4%). In total, 26.0% reported MH symptoms >10 days per month, and most adults (65.5%) scored in the borderline/abnormal range on the Hospital Anxiety and Depression Scale. Most (70.6%) respondents perceived their MH was negatively affected by AD in the past 12 months. AD severity impacted the perception of the relationship between AD and MH; respondents were more likely to believe MH was impacted by AD when they/their child had severe AD. Conclusion: Our study highlights patient and caregiver awareness of the detrimental impact of AD on MH. Addressing MH in AD care settings early in the disease journey may be beneficial.

Mental health interventions for atopic dermatitis: knowledge gaps, pilot programmes and future directions

Atopic dermatitis (AD) is associated with high levels of psychosocial burden, often resulting in poor mental health outcomes. Despite this association, few studies have evaluated the efficacy of mental health interventions within this population. Utilization of multidisciplinary and peer-led support, in addition to equipping patients with psychological tools, may be beneficial in improving mental health outcomes. Future research is needed to determine which interventions and formats are desired by, effective in and accessible to patients and caregivers with AD.
