A comparison of international treatment guidelines for Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis

Evaluation of the Factors Influencing Mortality in Patients with Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis: A Multicenter Study of 166 Patients

INTRODUCTION

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening acute mucocutaneous disorders usually triggered by drugs. In this study, we aimed to evaluate the factors affecting mortality in patients with SJS-TEN.

METHODS

Our study is a retrospective cohort study, analyzing data collected from a total of 12 tertiary care centers between April 2012 and April 2022.

RESULTS

The study included 59 males and 107 females, a total of 166 patients, with an average age of 50.91 ± 21.25 years. Disease classification was TEN in 50% of cases, SJS in 33.1%, and SJS-TEN overlap in 16.9%. The average SCORTEN within the first 24 h was 2.44 ± 1.42. Supportive care was provided to 99.4% of patients. The most commonly used systemic immunomodulatory treatments were systemic steroids (84.3%), IVIG (intravenous immunoglobulin) (49.3%), and cyclosporine (38.6%). Plasmapheresis was administered to five patients. While 66.3% of patients were discharged, 24.1% resulted in exitus. Our comparative analysis of survivors and deceased patients found no effect of systemic steroids, IVIG, and cyclosporine treatments on mortality. Univariate analysis revealed that the SCORTEN scores on days 1 and 3 as well as the rates of detachment at the onset and during follow-up were significantly higher in deceased patients compared to survivors. The rates of fever, positive blood cultures, and systemic antibiotic use were higher in deceased patients compared to survivors. The presence of comorbidities, diabetes, and malignancy were significantly more common in deceased patients. Multivariate regression analysis indicated that over SCORTEN 2, the mortality risk exponentially rose with each SCORTEN increment, culminating in an 84-fold increase in mortality at SCORTEN 5-6 (odds ratio [95% confidence interval]: 13.902-507.537, p < 0.001) compared to SCORTEN 0-1. Additionally, the utilization of plasmapheresis was associated with a 22-fold increase in mortality (odds ratio [95% confidence interval]: 1.96-247.2, p = 0.012).

CONCLUSION

Our study found that a high SCORTEN score within the first 24 h and the use of plasmapheresis were related to increased mortality, while systemic steroids, IVIG, and cyclosporine treatments had no impact on mortality. We believe that data gathered from one of the most comprehensive studies which we conducted on SJS-TEN will enrich the literature, although additional research is warranted.

Role of Silver Nitrate Spray for Skin Wound Care in Patients with Toxic Epidermal Necrolysis: Our Experience in 4 Patients

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are examples of severe cutaneous adverse reactions to drugs (SCARs) with several international recommendations for global medical management, ranging from pharmacological systemic therapy to skin wound care. There is no defined best management of the skin wounds in SJS/TEN. The care of wounds is essential to initiate re-epithelialization. Our objective is to improve the cicatrization process, avoiding scarring due to deepening of the wounds, as well as prevent infections, achieve pain control, and avoid loss of serum proteins, fluids, and electrolytes. In this retrospective case series, we highlight the value of systemic therapy and the use of silver nitrate for wound management in four patients with TEN.

Evolving trends in inpatient paediatric dermatology

PURPOSE OF REVIEW

This review provides updates in the evaluation and management of key dermatologic diseases encountered in the hospitalized child.

RECENT FINDINGS

Our understanding of dermatologic disorders in children continues to evolve. Staphylococcal scalded skin syndrome (SSSS) is a potentially severe blistering disorder typically seen in children under the age of 4 with an incidence that is increasing in the United States. Recent research has highlighted that the majority of cases are due to methicillin-sensitive Staphylococcus aureus (MSSA) and most patients can be adequately managed with beta-lactams. Toxic epidermal necrolysis (TEN) is one of the most feared dermatologic disorders. Currently, there is a lack of consensus on the most efficacious first-line systemic therapy. Etanercept is increasingly being used based on studies showing a shorter time to re-epithelization and decreased mortality. Lastly, the COVID-19 pandemic introduced the novel inflammatory condition multisystem inflammatory syndrome in children (MIS-C) in which approximately three out of four children present with a mucocutaneous eruption. Early recognition of the dermatologic features of MIS-C is important in potentially establishing a diagnosis and differentiating it from the many other causes of childhood fever and rash.

SUMMARY

There are no clear universal treatment guidelines for these rare diagnoses, and therefore, clinicians must remain informed of the latest findings in diagnosis and therapeutics.
