Comorbidities, mortality and survival in patients with pyoderma gangrenosum: a Danish nationwide registry-nested case-control study

Pyoderma Gangrenosum in a Patient with Crohn's Disease Treated with Adalimumab: A Case-Based Review and Systematic Review of the Current Literature

Background: Pyoderma gangrenosum (PG) is a rare inflammatory cutaneous disorder that frequently occurs in association with systemic diseases such as inflammatory bowel disease (IBD). This case report describes a 23-year-old female with Crohn's disease (CD) who developed PG and was successfully treated with adalimumab. The objective of this study is to present the clinical course, treatment approach, and outcomes while reviewing the existing literature on the efficacy of adalimumab in PG management. Methods: A case report is presented, detailing clinical presentation, diagnostic evaluation, and treatment strategy. Additionally, a systematic review was conducted using PubMed to assess studies on adalimumab in PG, focusing on treatment response, remission rates, and adverse effects. Results: The patient presented with ulcerative lesions on her lower extremities and sacroiliitis. After corticosteroid therapy, adalimumab was initiated, leading to significant ulcer healing, reduced back pain, and CD remission. The systematic review identified seven studies on adalimumab in PG. Findings suggest that adalimumab is effective in steroid-refractory cases, with remission achieved in a significant proportion of patients. The most common adverse effects were infections, but overall, adalimumab showed a favorable safety profile. Conclusions: This case highlights the importance of early diagnosis and multidisciplinary management of PG in CD patients. Adalimumab appears to be a promising therapeutic option, particularly for steroid-resistant PG, though further research is needed to establish standardized treatment protocols.

Updates in innovation of the treatment of pyoderma gangrenosum

INTRODUCTION

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis characterized by rapidly enlarging, painful ulcers with undermined borders. The management of PG is challenging due to the lack of standardized evidence-based treatments.

AREAS COVERED

This review examines recent efforts to establish standardized outcomes for clinical trials to facilitate the drug development process for PG. It explores new therapeutics in development and evaluates advanced options for wound and pain management. Literature available on the pathogenesis, treatment, and pain management of PG from database inception to April 2024 was searched in PubMed, Embase, and Cochrane. ClinicalTrials.gov and the EU Clinical Trials Register were searched for clinical trials on PG.

EXPERT OPINION

New therapeutics such as interleukin 36 inhibitor and complement component C5a inhibitor more specifically target key pathways in the pathogenesis of PG have shown promise and can greatly benefit patients with PG, which still lacks an FDA-approved treatment. In addition to systemic therapy, local wound care and pain management should be carried out simultaneously to achieve successful wound healing.

Estimating mortality in rare diseases using a population-based registry, 2002 through 2019

BACKGROUND

Rare diseases (RD) are a heterogeneous group of diseases, sharing aspects of complexity. Prognosis is variable, even in individuals with the same disease. Real-world data on RD as a whole are scarce. The aim of this study is to provide data on mortality and survival for a substantial group of RD deriving from a population-based registry, which covers the Veneto region in Italy (4.9 million inhabitants).

RESULTS

During the study period, 3367 deaths occurred, mainly in males (53.9%), elderly patients (63.5%) and patients with diseases having a reported prevalence of 1-9/100000 (65.6%). When standardizing by age, the mortality ratio was higher in RD patients than in the general population, SMR = 1.93 (95% CI 1.84-2.11), with an observed gender difference, 2.01 (95% CI 1.88-2.29) in females and 1.86 (95% CI 1.73-2.10) in males. The lowest survival rates are experienced by patients with rare neurologic diseases, rare skin diseases and rare systemic or rheumatologic diseases, 58%, 68% and 81%, respectively, after a 15-year observation period. It should be noted that only 18% of patients diagnosed with motor neuron diseases were alive after 15 years from diagnosis.

CONCLUSIONS

Despite progress in diagnosis, treatment and care in recent years, RD patients globally have higher mortality rates and reduced survival compared to the general population, with specific variations according to gender, age and disease group.

Treatment Strategies in Neutrophilic Dermatoses: A Comprehensive Review

Neutrophilic dermatoses (NDs) are a group of noninfectious disorders characterized by the presence of a sterile neutrophilic infiltrate without vasculitis histopathology. Their physiopathology is not fully understood. The association between neutrophilic dermatoses and autoinflammatory diseases has led some authors to propose that both are part of the same spectrum of diseases. The classification of NDs depends on clinical and histopathological features. This review focuses on the recent developments of treatments in these pathologies.
