Abstract
INTRODUCTION Stevens Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are serious conditions that carry a high rate of morbidity and mortality. OBJECTIVE This review highlights the pearls and pitfalls of SJS/TEN, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION SJS/TEN is a rare, delayed hypersensitivity reaction resulting in de-epithelialization of the skin and mucous membranes. The majority of cases are associated with medication or infection. Clinicians should consider SJS/TEN in any patient presenting with a blistering mucocutaneous eruption. Evaluation of the skin, mucosal, pulmonary, renal, genital, and ocular systems are essential in the diagnosis of SJS/TEN, as well as in the identification of complications (e.g., sepsis). Laboratory and radiological testing cannot confirm the diagnosis in the ED setting, but they may assist in the identification of complications. ED management includes stabilization of airway and breathing, fluid resuscitation, and treatment of any superimposed infections with broad-spectrum antibiotic therapy. All patients with suspected SJS/TEN should be transferred and admitted to a center with burn surgery, critical care, dermatology, and broad specialist availability. CONCLUSIONS An understanding of SJS/TEN can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are immune-mediated skin reactions with high mortality as a result of severely compromised skin barrier function. Currently, there is no consensus on the topical management of these conditions. Some advocate for surgical debridement of affected skin as a means of preventing infection and facilitating reepithelialization with synthetic and biological wound coverage. Others prefer a conservative approach that relies on leaving the blistered skin in situ. A consensus is lacking, primarily due to the rarity of the disease and the lack of high-quality evidence supporting one particular form of management. The goal of this review is to explore and compare the two treatment approaches for SJS and TEN, namely conservative management and surgical debridement.

An individual patient data meta-analysis of wound care in patients with toxic epidermal necrolysis. Australas J Dermatol 2024; 65:128-142. [PMID: 38063272 DOI: 10.1111/ajd.14193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 10/20/2023] [Accepted: 11/19/2023] [Indexed: 03/10/2024]
Abstract
Toxic epidermal necrolysis (TEN) involves extensive mucocutaneous loss, and care is supportive. The approach to wound care includes surgical debridement or using dressings while leaving the epidermis intact. Robust evidence for either approach is lacking. We compared surgical debridement to the use of dressings while leaving the epidermis in situ (referred to hereon as dressings) in adult patients with TEN. The primary outcome assessed was mortality. The secondary outcome was time to re-epithelialisation. The impact of medications was evaluated. An individual patient data (IPD) systematic review and meta-analysis was undertaken. A random effects meta-analysis and survival analysis for IPD data examined mortality, re-epithelisation time and the effect of systemic medications. The quality of evidence was rated per the Grading of Recommendations Assessment, Development and Evaluation (GRADE). PROSPERO: CRD42021266611 Fifty-four studies involving 227 patients were included in the systematic review and meta-analysis, with a GRADE from very low to moderate. There was no difference in survival in patients who had surgical debridement or dressings (univariate: p = 0.91, multivariate: p = 0.31). Patients who received dressings re-epithelialised faster than patients who underwent debridement (multivariate HR: 1.96 [1.09-3.51], p = 0.023). Intravenous immunoglobulin (univariate HR: 0.21 [0.09-0.45], p < 0.001; multivariate HR: 0.22 [0.09-0.53], p < 0.001) and cyclosporin significantly reduced mortality (univariate HR: 0.09 [0.01-0.96], p = 0.046; multivariate HR: 0.06 [0.01-0.73], p = 0.028) irrespective of the wound care. This study supports the expert consensus of the dermatology hospitalists, that wound care in patients with TEN should be supportive with the epidermis left intact and supported with dressings, which leads to faster re-epithelialisation.

Abstract
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe drug-induced hypersensitivity reactions characterized by widespread epidermal necrosis, mucous membrane erosions, and systemic findings. We have provided our 11-year experience from a Milan, Italy tertiary hospital managing SJS/TEN, evaluating the clinical and histopathologic features plus the impact on mortality. We retrospectively analyzed 28 patients diagnosed with SJS/TEN based on the clinical and histopathologic findings, according to the classification criteria of multiple studies. We assessed the dermatographics, comorbidities, drug history, lesion characteristics, clinical findings, treatments, blood tests, and outcomes. Severity scores (SCORTEN, Re-SCORTEN, ABCD-10) were used for treatment evaluation and mortality prediction. Data were statistically analyzed, and significant factors associated with mortality were identified. We found that among the 28 patients, 89.2% had comorbidities, mainly cardiovascular diseases, and 21.4% had autoimmune disorders. All patients had received systemic therapy (46.6% monotherapy, 53.6% combination therapy), with systemic steroids (71.4%) and intravenous immunoglobulins (67.8%) being common treatments. There were complications, including systemic infections (67.9%) and septic shock (10.7%). The overall mortality rate was 17.8%. The statistical analysis indicated that malignancy, a high ABCD-10 score, and a high neutrophil-to-lymphocyte ratio were significantly associated with mortality. The extent of affected body surface area did not correlate significantly with mortality. This study provides insights into SJS/TEN management, revealing factors influencing mortality in a high-complexity tertiary hospital setting.

Sedation and Analgesia for Toxic Epidermal Necrolysis in the Intensive Care Unit: Few Certainties, Many Questions Ahead. J Pers Med 2023; 13:1194. [PMID: 37623445 PMCID: PMC10455435 DOI: 10.3390/jpm13081194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 07/25/2023] [Accepted: 07/26/2023] [Indexed: 08/26/2023] Open
Abstract
Toxic epidermal necrolysis (TEN) is a rare, acute mucocutaneous life-threatening disease. Although research has focused on the pathophysiological and therapeutic aspects of the disease, there is a paucity of data in the literature regarding pain management and sedation in the intensive care unit (ICU). Most therapies have been extrapolated from other situations and/or the general ICU population. These patients present unique challenges during the progression of the disease and could end up requiring invasive mechanical ventilation due to inadequate pain management, which is potentially avoidable through a comprehensive treatment approach. In this review, we will present clinical and pathophysiological aspects of TEN, analyze pain pathways and relevant pharmacology, and propose therapeutic alternatives based on a rational and multimodal approach.

Photodistributed Stevens-Johnson syndrome and toxic epidermal necrolysis: a systematic review and proposal for a new diagnostic classification. Eur J Med Res 2023; 28:188. [PMID: 37303053 DOI: 10.1186/s40001-023-01142-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Accepted: 05/15/2023] [Indexed: 06/13/2023] Open
Abstract
BACKGROUND Ultraviolet radiation (UVR) exposure is commonly reported as a risk factor for Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). However, minimal evaluation of photo-induced SJS/TEN has been conducted. Thus, this review identifies all cases of SJS/TEN that are linked to an acute exposure of UVR and outlines the unifying characteristics of these cases. Furthermore, the theoretical pathogenesis, differential diagnoses, and proposed diagnostic criteria are defined. METHODS PubMed, Google Scholar, and other databases and websites were searched from inception to September 2021 to identify studies that met inclusion criteria. The following keywords were utilized: "Stevens-Johnson syndrome" and "toxic epidermal necrolysis" with "ultraviolet," "photodistributed," "photo-induced," "photosensitivity," and "photo." One reviewer assessed study characteristics, with confirmation by a second. The risk of bias was assessed independently by another. RESULTS Thirteen patient cases were identified, all reporting ultraviolet radiation prior to rash onset and an underlying causal drug. Case classifications included 7/13 SJS and 6/13 TEN. All cases described the rash as photodistributed with UVR exposure prior to rash onset (delay of 1-3 days) and a causal drug. 10 cases provided evidence that the photodistributed rash lacked linear demarcation (as in a sunburn) with satellite target-like lesions. No cases described a flu-like prodrome. DISCUSSION Mucositis, palmar and plantar rash, a positive Nikolsky sign, and a prolonged disease course can help distinguish from photosensitive reactions, while a negative direct immunofluorescence test is important to distinguish from other photo-induced disorders. CONCLUSION Physicians should be aware that UVR may precipitate SJS/TEN in patients taking susceptible drugs. After a 24-h delay from UVR exposure, a non-distinct, photodistributed rash appears with no flu-like prodrome and progresses for at least 48 h to include vesiculobullous eruptions and mucous membrane involvement. Photodistributed SJS/TEN appears to be photo-drug-induced with a unique onset and rash presentation that should be recognized as a distinct diagnosis.

Abstract
Toxic epidermal necrolysis (TEN) is a dermatological process which has lacked both clear pathophysiological definition and efficacious medical treatment. This leads to metabolic dysfunction due to the inability to regulate fluid and electrolytes after the loss of skin. It is a deadly and costly disease which is associated with long lengths of stay and high-mortality rates. The depth of TEN mimics that of a partial-thickness burn. There has been documentation of successful usage of autologous skin cell suspension (ASCS) in TEN. This study expands upon our previous experience using ASCS in TEN to a series of three. Dermatology is consulted for biopsy along with the burn surgery team for wound care, where a Score for TEN is performed for risk stratification. Aggressive operative debridement is performed in the operative suite and a healthy, uninvolved donor site is harvested and processed per standard protocol. Dressings are taken down at postoperative day 4 for evaluation. The average length of stay when compared to historical data in literature is a reduction by 48%. ICU days were reduced by 64%. Cost was reduced by 54%. There was no mortality in our population of three. ASCS is both therapeutically and cost effective at treating TEN. The question of type of dressing and decision to operate is mitigated by this intervention. As an efficacious intervention, it reduces hospital stay, reduces wound cares, speeds healing, and provides a cosmetically acceptable outcome.

Abstract
Importance Antibiotics are an important risk for Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN), which are the most severe types of drug hypersensitivity reaction with a mortality rate up to 50%. To our knowledge, no global systematic review has described antibiotic-associated SJS/TEN. Objective To evaluate the prevalence of antibiotics associated with SJS/TEN worldwide. Data Sources The MEDLINE and Embase databases were searched for experimental and observational studies that described SJS/TEN risks since database inception to February 22, 2022. Study Selection Included studies adequately described SJS/TEN origins and specified the antibiotics associated with SJS/TEN. Data Extraction and Synthesis Two reviewers (E.Y.L. and C.K.) independently selected the studies, extracted the data, and assessed the risk of bias. A meta-analysis using a random-effects model was performed in the studies that described patient-level associations. Subgroup analyses were performed to explore the heterogeneity. The risk of bias was assessed using the Joanna Briggs Institute checklist, and the certainty of evidence was rated using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. Main Outcomes and Measures Prevalence of antibiotic-associated SJS/TEN was presented as pooled proportions with 95% CIs. Results Among the 64 studies included in the systematic review, there were 38 studies that described patient-level associations; the meta-analysis included these 38 studies with 2917 patients to determine the prevalence of single antibiotics associated with SJS/TEN. The pooled proportion of antibiotics associated with SJS/TEN was 28% (95% CI, 24%-33%), with moderate certainty of evidence. Among antibiotic-associated SJS/TEN, the sulfonamide class was associated with 32% (95% CI, 22%-44%) of cases, followed by penicillins (22%; 95% CI, 17%-28%), cephalosporins (11%; 95% CI, 6%-17%), fluoroquinolones (4%; 95% CI, 1%-7%), and macrolides (2%; 95% CI, 1%-5%). There was a statistically significant heterogeneity in the meta-analysis, which could be partially explained in the subgroup analysis by continents. The overall risk of bias was low using the Joanna Briggs Institute checklist for case series. Conclusion and Relevance In this systematic review and meta-analysis of all case series, antibiotics were associated with more than one-quarter of SJS/TEN cases described worldwide, and sulfonamide antibiotics remained the most important association. These findings highlight the importance of antibiotic stewardship, clinician education and awareness, and weighing the risk-benefit assessment of antibiotic choice and duration.

Abstract
Background Sintilimab is a fully human monoclonal antibody targeting PD-1, which has been considered well tolerated among patients and widely applied in malignancies. Case Presentation We present a case report of a patient with gallbladder carcinoma treated with sintilimab who developed toxic epidermal necrolysis (TEN). A 72-year-old female presented with fever and maculopapular rash after receiving one dose of sintilimab for metastatic gallbladder carcinoma. Widespread maculopapular rashes with progressive skin detachment occurred within one week. Early skin biopsy of the patient showed apoptotic keratinocytes along with interface dermatitis. She was initially treated with escalating methylprednisolone (from 0.8 to 1.6 mg/kg/d) and subsequently in the combination of intravenous immunoglobulin. Her skin lesions significantly improved, and satisfying re-epithelialization was achieved after 43 days of hospitalization. Conclusion Because of the high mortality of grade four immune related adverse event (irAE) on skin, we recommend early monitoring and recognition of symptoms. During management, high-dose glucocorticoids with combined intravenous immune globulin and supportive care may be helpful.

Intravenous Immunoglobulin Combined With Corticosteroids for the Treatment of Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis: A Propensity-Matched Retrospective Study in China. Front Pharmacol 2022; 12:750173.

Abstract
Background: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threatening severe adverse drug reactions. The use of corticosteroids and intravenous immunoglobulin (IVIg) in SJS/TEN remains controversial. Methods: In this single-center, observational, propensity-matched, retrospective study, we collected a total of 224 patients with SJS/TEN who were hospitalized in our department from 2008 to 2019; according to treatment with IVIg combined with corticosteroids or with corticosteroids alone, patients were divided into combination therapeutic group (163 patients) and monotherapeutic group (61 patients). Patients from the two groups were matched by their propensity score in blocks of 2:1. Comparisons of the clinical characteristics and prognoses between propensity-matched SJS/TEN patients treated with IVIg combined with corticosteroids and corticosteroids alone were made. Results: After our propensity matching, a total of 145 patients were yielded, including 93 patients treated with IVIg and 52 patients not treated with IVIg. All of the 23 variables reflected good matching between patients treated with/without IVIg, and no significant difference was observed. Although there was no significant difference between the totally predicted and actual mortality in both of our groups, the actual mortality was lower than it was predicted in patients treated with IVIg [p > 0.250, the standardized mortality ratio (SMR) was 0.38, 95% CI 0.00-0.91] and patients treated without IVIg (p = 1.000, the SMR was 0.75, 95% CI 0.00-1.76). IVIg tended toward reducing the time to arrest of progression by 1.56 days (p = 0.000) and the length of hospital stay by 3.37 days (p = 0.000). The mortality rate was 45% lower for patients treated with IVIg combined with corticosteroids than those only treated with corticosteroid therapy, although it was not statistically significant (p = 0.555). The incidence of skin infections was significantly lower in the combined therapy group (p < 0.025), and the total infection rate of patients treated with combination therapy tended to decrease by 67% compared to patients treated with corticosteroids alone (p = 0.047). Conclusion: The actual mortality rate of patients treated with corticosteroids alone or IVIg combined with corticosteroids tended to be lower than those predicted by TEN-specific severity-of-illness score (SCORTEN), although there was no significance. Compared with those treated by corticosteroids alone, combination therapy was prone to bring a better prognosis for SJS/TEN patients.

Abstract
Background: Stevens–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are acute, life-threatening, severe drug reactions. Randomized studies on these diseases are difficult to perform. Aims and Objectives: The purpose of this study was to summarize the demographic and clinical characteristics of patients with SJS and TEN in a tertiary hospital in Turkey. Materials and Methods: We evaluated the records of 33 patients with SJS and TEN who were followed in our clinic or examined between January 2008 and June 2019, retrospectively. Age, sex, time of admission to hospital, causative drug, presence of concomitant disease, skin findings, mucosal involvement, the severity-of-illness score for TEN, the medication used, antibiotic use, transfer to intensive care, development of complications, and death or discharge status were noted. Results: Of the 33 patients, 11 (33.3%) had SJS, 3 (9.1%) had SJS/TEN overlap, and 19 (57.6%) had TEN. The majority (60.6%) of the patients were female. Nineteen (57.6%) patients had one, and 13 (39.4%) had more than one suspected drug exposure in their history. The most commonly suspected drugs were antibiotics. Twelve (36.4%) patients had intensive care unit hospitalization. Ten (30.3%) patients died. Conclusion: The demographic data of our study were consistent with the literature. Similar to the literature, antibiotics were the most common reaction-causing drugs. However, antiepileptic drugs, which were more frequently reported in other studies, were identified as suspicious in only one patient. We believe that our study will contribute to the determination of characteristics of this rare disease with real-life data.

Abstract
Toxic epidermal necrolysis is a drug-mediated disease process which mimics a partial thickness thermal injury. It has long been treated with frequent wound dressing changes and supportive care. There has been minimal efficacious system therapy. The pathophysiology is poorly understood but causes necrosis of keratinocytes at the dermal-epidermal junction leading to sloughing of the epidermis. The disease is rare with high mortality rates associated with long hospital stays. This case report describes the application of autologous skin cell suspension to a patient with toxic epidermal necrolysis after antihypertensive and hyperglycemic therapy. This was associated with minimal wound care and efficacious arrest of patient disease process and timely closure of wound.

Abstract
Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a rare adverse cutaneous reaction with a low incidence and high mortality. Despite posing a serious threat to patients' health and lives, there is no high-quality evidence for a standard treatment regimen. Here we report the case of a 62-year-old man with stage IV pancreatic cancer who experienced immunotherapy-induced SJS/TEN. After consensus-based regular treatments at a local hospital, his symptoms became worse. Thus, he consented to receive Chinese herbal medicine (CHM) therapy. The affected parts of the patient were treated with the CHM Pi-Yan-Ning which was applied externally for 20 min twice a day. After 7 days of treatment, the dead skin began peeling away from the former lesions that had covered his hands, feet, and lips, indicating that skin had regenerated. After 12 days of treatment, the patient's skin was completely recovered. In this case, SJS/TEN was successfully treated with Pi-Yan-Ning, suggesting that there might be tremendous potential for the use of Pi-Yan-Ning in the treatment of severe skin reactions to drug treatments. Further basic investigations and clinical trials to explore the mechanism and efficacy are needed.

Abstract
Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are rare diseases that are characterized by widespread epidermal necrosis and sloughing of skin. They are associated with significant morbidity and mortality, and early diagnosis and treatment is critical in achieving favorable outcomes for patients. In this scoping review, Excerpta Medica dataBASE and PubMed were searched for publications that addressed recent advances in the diagnosis and management of the disease. Multiple proteins (galectin 7 and RIP3) were identified that are promising potential biomarkers for SJS/TEN, although both are still in early phases of research. Regarding treatment, cyclosporine is the most effective therapy for the treatment of SJS, and a combination of intravenous immunoglobulin (IVIg) and corticosteroids is most effective for SJS/TEN overlap and TEN. Due to the rare nature of the disease, there is a lack of prospective, randomized controlled trials and conducting these in the future would provide valuable insights into the management of this disease.

Background: Toxic epidermal necrolysis (TEN) is a rare life-threatening disease that mainly affects the skin and mucous membranes, resulting from a toxic delayed-type hypersensitivity (DTH) reaction (type IV reaction) to the presence of foreign antigens such as drugs. The clinical symptoms are caused by pathophysiological processes leading to massive apoptosis of keratinocytes in the dermo-epidermal junction. This results in the formation of a bulla and subsequent separation of the entire epidermis with the exposure of the dermis. The current approach in the local therapy of TEN prefers the use of biological dressings, which helps provide several critical requirements for defect healing; in particular, it helps in the acceleration of the spontaneous wound closure (re-epithelialization) of the skin defect and the reduction of the risk of development of various complications and infections, such as the risk of pathological scar maturation. This paper is a case report of the use of a lyophilized amniotic membrane (AM) for accelerating wound healing in a patient with TEN. Case Presentation: We report a case of an 8-year-old girl transferred to our center with a histologically confirmed diagnosis of TEN. Despite the application of immunosuppressive therapy consisting of corticosteroids and intravenous immunoglobulins, we have observed disease progression and exfoliation of up to 60% of the total body surface area (TBSA). In the facial area, which is cosmetically privileged, we decided to use the lyophilized amniotic membrane (Amnioderm®) to cover up approximately 2% of the TBSA. Within 2 days after the application, we observed accelerated reepithelialisation, with rapid wound closure. We have not observed any side effects nor infections during the subsequent phases of wound healing. Skin defects in non-facial areas of the body were treated with synthetic dressings. When compared to the areas covered with the lyophilized AM, the healing process was prolonged. Conclusions: To our knowledge, this is the first case study using a lyophilized amniotic membrane in the treatment of a patient with TEN. The AM application in the cosmetically-privileged area (face), proved to be very efficient in the treatment of TEN patients. The use of this allogeneic material demonstrated excellent biocompatibility and caused a unique acceleration of epithelialization and wound healing, yielding also excellent long-term results. The current study opens broad possibilities for clinical application of the used material, the improvement of current therapy of patients with TEN and better outcomes and recovery of patients.

Autologous scalp skin grafting to treat toxic epidermal necrolysis in a patient with a large skin injury: A case report. World J Clin Cases 2021; 9:1646-1653. [PMID: 33728308 PMCID: PMC7942035 DOI: 10.12998/wjcc.v9.i7.1646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 11/26/2020] [Accepted: 12/10/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Toxic epidermal necrolysis (TEN) is often associated with skin wounds affecting large areas. Healing of this type of wound is difficult because of pressure, infection and other factors. It can increase the length of hospital stay and result in wound sepsis and even death.
CASE SUMMARY A 49-year-old woman developed a skin lesion covering 80% of the total body surface area after using a kind of Chinese medicinal ointment on a burn wound on her back; she developed life-threatening wound sepsis and septic shock. Methicillin-resistant Staphylococcus aureus, carbapenem-resistant Acinetobacter baumannii, carbapenem-resistant Pseudomonas aeruginosa and other bacteria were cultured from wound tissue, deep venous catheter and blood samples. Imipenem cilastatin sodium, tigecycline and teicoplanin were used for anti-infection therapy. Finally, the patient was transferred to the burn department because of severe wound sepsis. In the burn intensive care unit, pain-free dressing changes and autologous scalp skin grafting were performed to heal the wound in addition to reasonable and effective antibacterial treatment according to microbial susceptibility test results. After three operations within 2 wk, the wound healed and sepsis resolved.
CONCLUSION TEN patients with large areas of skin injury may develop wound infection and life-threatening wound sepsis. Autologous scalp skin grafting may be beneficial for rapid wound healing and reducing the risk of sepsis in TEN patients, and it leaves no scar at the donor site.

Impact of Antibiotics Associated with the Development of Toxic Epidermal Necrolysis on Early and Late-Onset Infectious Complications. Microorganisms 2021; 9:microorganisms9010202. [PMID: 33477980 PMCID: PMC7835845 DOI: 10.3390/microorganisms9010202] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2021] [Revised: 01/14/2021] [Accepted: 01/15/2021] [Indexed: 01/01/2023] Open
Abstract
Toxic epidermal necrolysis (TEN) is a rare disease, which predominantly manifests as damage to the skin and mucosa. Antibiotics count among the most common triggers of this hypersensitive reaction. Patients with TEN are highly susceptible to infectious complications due to the loss of protective barriers and immunosuppressant therapy. The aim of this study was to investigate the potential relationship between antibiotics used before the development of TEN and early and late-onset infectious complications in TEN patients. In this European multicentric retrospective study (Central European Lyell syndrome: therapeutic evaluation (CELESTE)), records showed that 18 patients with TEN used antibiotics (mostly aminopenicillins) before the disease development (group 1), while in 21 patients, TEN was triggered by another factor (group 2). The incidence of late-onset infectious complications (5 or more days after the transfer to the hospital) caused by Gram-positive bacteria (especially by Enterococcus faecalis/faecium) was significantly higher in group 1 than in group 2 (82.4% vs. 35.0%, p = 0.007/pcorr = 0.014) while no statistically significant difference was observed between groups of patients with infection caused by Gram-negative bacteria, yeasts, and filamentous fungi (p > 0.05). Patients with post-antibiotic development of TEN are critically predisposed to late-onset infectious complications caused by Gram-positive bacteria, which may result from the dissemination of these bacteria from the primary focus.

Abstract
The ojective of this study was to describe the reasons for admission to the burn center of patients with autoimmune rheumatic diseases (ARD), identify their clinical characteristics, and assess their outcomes relative to the non-ARD patients. We conducted a retrospective study of ARD patients admitted to a burn center from 2011 to 2018, and they were compared with a non-ARD group of patients. Medical records were reviewed for patients' clinical characteristics, including demographics, ARD diagnosis, laboratory studies, and APACHE II score. Additionally, we evaluate the reason for admission in the burn center, management during the burn center stay, complications, outcomes including length of stay, and mortality during the hospital stay. Among the 1094 adult patients admitted during the study period, 30 (2.7%) had a new or prior diagnosis of ARD. The most common ARD associated with admission in the burn center was rheumatoid arthritis (RA) (37%, n = 11) followed by systemic lupus erythematosus (SLE) (33%, n = 10). Burn injuries (47%, n = 14), and Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) (30%, n = 9) were the most frequent admission reasons. Compared with the non-ARD group (n = 52), ARD patients were more likely to be females (60% vs. 24%, P = 0.004), to receive glucocorticoids (50% vs. 6.9%; P < 0.05), require renal replacement (20% vs. 5%, P < 0.05) and enteral nutrition (63% vs. 24%; P < 0.05) during their burn stay. The non-ARD group was more likely to be admitted for burn injuries (81% vs 46%, P < 0.01). RA and SLE were the most common ARD, and burn injuries, followed by SJS/TEN, the most frequent causes associated with burn admissions. ARD patients were more likely to be female, received glucocorticoids, require renal replacement, and enteral nutrition during the burn stay.

Abstract
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening conditions with high morbidity and mortality. Supportive care management of SJS/TEN is highly variable. A systematic review of the literature was performed by dermatologists, ophthalmologists, intensivists, and gynecologists with expertise in SJS/TEN to generate statements for supportive care guideline development. Members of the Society of Dermatology Hospitalists with expertise in SJS/TEN were invited to participate in a modified, online Delphi-consensus. Participants were administered 9-point Likert scale questionnaires regarding 135 statements. The RAND/UCLA Appropriateness Method was used to evaluate and select proposed statements for guideline inclusion; statements with median ratings of 6.5 to 9 and a disagreement index of ≤1 were included in the guideline. For the final round, the guidelines were appraised by all of the participants. Included are an evidence-based discussion and recommendations for hospital setting and care team, wound care, ocular care, oral care, urogenital care, pain management, infection surveillance, fluid and electrolyte management, nutrition and stress ulcer prophylaxis, airway management, and anticoagulation in adult patients with SJS/TEN.

Abstract
BACKGROUND Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is an autoimmune condition with significant morbidity and mortality. METHODS A retrospective review was performed at a single institution. All patients admitted to the LAC+USC burn unit from May 1st 2015-January 1st 2018 with a histologic diagnosis of SJS/TEN were reviewed. Patient characteristics and outcomes were recorded. These outcomes were compared to our previously published cohort. RESULTS Thirteen total consecutive SJS/TEN patients were treated with etanercept. Compared to non-etanercept treated patients, etanercept-treated patients did not experience a significant difference in mortality (15.4% vs. 10%, P=0.58), ICU days (6.9 vs. 15.1, P=0.08), length-of-stay (9.8 vs 16.4, P=0.11), or infections (38.5% vs. 57.5%, P=0.58). The standardized mortality ratio in etanercept-treated patients was 0.44 (95% CI, 0.21, 0.65). In general, etanercept-treated patients had higher SCORTENs (3 vs. 2, P=0.03) and longer delays to presentation (5.2 vs. 2.7 days, P<0.01). CONCLUSIONS Etanercept can be considered in the treatment of SJS/TEN patients in addition to IVIg, and supportive care in a burn unit.

Abstract
RATIONALE Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are 2 rare but life-threatening diseases characterized by detachment of epidermis, bullous skin lesions, and mucous membrane erosions. Drugs are highly suspected to be the causative agents. We report a case of SJS/TEN induced by oseltamivir, which is a very rare event. PATIENT CONCERNS A 9-year-old girl with upper respiratory tract infections presented with generalized maculopapular rash the second day after taking oseltamivir. DIAGNOSIS The diagnosis of SJS/TEN was made based on cytotoxic skin lesions and mucous membrane involvement. INTERVENTIONS After discontinuing of the drug and combination therapy of corticosteroid and human immunoglobulin initiation, the lesions were improved. Human leukocyte antigen (HLA) gene sequencing was done. OUTCOMES The girl was followed-up for 1 year. The skin and mucous membranes symptoms were relieved. LESSONS We report this case to attract attention to the rare but serious side effect of this antiviral drug.

Abstract
Stevens-Johnson syndrome (SJS) is a disease that causes skin exfoliative lesions, characterized by fever, necrosis, and epidermal detachment. Biological skin substitutes may be considered interesting options for the treatment of this disease. This study aims at identifying in the literature the evidence on the current role of these biomaterials in the treatment of SJS and its related diseases. A systematic review with a search period between 2003 and 2017 was carried out, consulting the Lilacs, BVS, and PubMed databases. The quality of the included studies was evaluated by the Oxford Center for Evidence-Based Medicine Classification, for evaluating levels of evidence from the scientific publications. Ninety-five publications were found, and after applying inclusion and exclusion criteria, they resulted in 9 articles. In total, 20 patients with 73.87% average of body surface affected received SJS skin treatment with some biological substitutes, among them are cutaneous allograft, amnion, and xenograft. Mortality rate was 10%, and in these situations, literature indicates mortality rates ranging from 25% to 70%. Effectiveness of the use of biological dressings may be a possible explanation for this finding. Findings indicate the use of these biomaterials may favor reepithelialization, reduce water loss, decrease the chance of infection, and, consequently, improve the survival of patients with SJS and toxic epidermal necrolysis. Biological skin substitutes have characteristics that make them very promising in the topical treatment of these wounds, but their use remains very restricted in the treatment of SJS.

Abstract
BACKGROUND Hypersensitivity reactions (HSRs) are immunologic responses to drugs. Identification of HSRs documented in the electronic health record (EHR) is important for patient safety. OBJECTIVE To examine HSR epidemiology using longitudinal EHR data from a large United States health care system. METHODS Patient demographic information and drug allergy data were obtained from the Partners Enterprise-wide Allergy Repository for 2 large tertiary care hospitals from 2000 to 2013. Drug-induced HSRs were categorized into immediate and delayed HSRs based on typical phenotypes. Causative drugs and drug groups were assessed. The prevalence of HSRs was determined, and sex and racial differences were analyzed. RESULTS Among 2.7 million patients, 377,474 (13.8%) reported drug-induced HSRs, of whom 70.3% were female and 77.5% were white. A total of 580,456 HSRs were reported, of which 53.1% were immediate reaction phenotypes. Common immediate HSRs included hives (48.8%), itching (15.0%), and angioedema (14.1%). Delayed HSR phenotypes (46.9%) were largely rash (99.0%). Penicillins were associated with the most immediate (33.0%) and delayed (39.0%) HSRs. Although most HSRs were more prevalent in females and white patients, notable differences were identified for certain rare HSRs including acute interstitial nephritis, which appeared more commonly in males (0.02% vs 0.01%, P < .001). Asian patients had more fixed drug eruptions (0.007% vs 0.002%, P = .021) and severe cutaneous adverse reactions (0.05% vs 0.04%, P < .001). CONCLUSIONS Drug HSRs were reported in 13.8% of patients. Almost one-half of reported immediate HSR phenotypes were hives, and almost all reported delayed HSR phenotypes were rash. HSRs largely affected female and white patients, but differences were identified for specific rare HSRs.

Abstract
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are considered a delayed-type hypersensitivity reaction to drugs. They represent true medical emergencies and an early recognition and appropriate management is decisive for the survival. SJS/TEN manifest with an "influenza-like" prodromal phase (malaise, fever), followed by painful cutaneous and mucous membrane (ocular, oral, and genital) lesions, and other systemic symptoms. The difference between SJS, SJS/TEN overlap, and TEN is defined by the degree of skin detachment: SJS is defined as skin involvement of < 10%, TEN is defined as skin involvement of > 30%, and SJS/TEN overlap as 10-30% skin involvement. The diagnosis of different degrees of epidermal necrolysis is based on the clinical assessment in conjunction with the corresponding histopathology. The mortality rates for SJS and TEN have decreased in the last decades. Today, the severity-of-illness score for toxic epidermal necrolysis (SCORTEN) is available for SJS/TEN severity assessment. Drugs with a high risk of causing SJS/TEN are anti-infective sulfonamides, anti-epileptic drugs, non-steroidal anti-inflammatory drugs of the oxicam type, allopurinol, nevirapine, and chlormezanone. Besides conventional drugs, herbal remedies and new biologicals should be considered as causative agents. The increased risk of hypersensitivity reactions to certain drugs may be linked to specific HLA antigens. Our understanding of the pathogenesis of SJS/TEN has improved: drug-specific T cell-mediated cytotoxicity, genetic linkage with HLA- and non-HLA-genes, TCR restriction, and cytotoxicity mechanisms were clarified. However, many factors contributing to epidermal necrolysis still have to be identified, especially in virus-induced and autoimmune forms of epidermal necrolysis not related to drugs. In SJS/TEN, the most common complications are ocular, cutaneous, or renal. Nasopharyngeal, esophageal, and genital mucosal involvement with blisters, erosions as well as secondary development of strictures also play a role. However, in the acute phase, septicemia is a leading cause of morbidity and fatality. Pulmonary and hepatic involvement is frequent. The acute management of SJS/TEN requires a multidisciplinary approach. Immediate withdrawal of potentially causative drugs is mandatory. Prompt referral to an appropriate medical center for specific supportive treatment is of utmost importance. The most frequently used treatments for SJS/TEN are systemic corticosteroids, immunoglobulins, and cyclosporine A.

Abstract
OBJECTIVE To provide a brief overview of the clinical presentation, common offending agents, management, prognosis, and mortality of 6 selected high-risk drug rashes, namely, Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome, multiple drug hypersensitivity (MDH) syndrome, acute generalized exanthematous pustulosis (AGEP), and drug-induced bullous pemphigoid (DIBP). DATA SOURCES A review of the published literature was performed with PubMed and supplemented with our clinical experience. STUDY SELECTIONS The most recent clinically relevant studies and older seminal works were selected. RESULTS Most of the published data on these uncommon rashes were based on small observational series or case reports. SJS and TEN have specific genotypes association with certain drugs, have high morbidity and mortality, and require aggressive management by a team of multiple specialists. DRESS syndrome is a severe, prolonged multiorgan reaction, yet it has a better prognosis than TEN. MDH is a syndrome of repeated reactions to unrelated drugs that often imposes diagnostic and management difficulties. AGEP consists of generalized sterile small pustules, usually mistaken for infection with subsequent inappropriate treatment. Bullous pemphigoid presents with tense pruritic bullae and characteristic linear basement membrane deposition of IgG and C3. DIBP has much better prognosis than the autoimmune variety. CONCLUSION In such high-risk drug rashes, early recognition, immediate withdrawal of the suspected drug(s), prompt individualized management, and monitoring of vital organs function are mandatory for reducing morbidity and mortality. The lack of reliable tests for identification of the causative agent imposes difficulty, particularly in patients receiving multiple medications.

Abstract
Background Contrary to popular perception, several dermatological conditions may be associated with lethal outcome in the absence of timely intervention or due to complications. Aims The aim was to estimate the number of deaths and analyze their causes due to skin disorders at a tertiary level inpatient dermatology ward. Materials and Methods We conducted a retrospective, record-based observational study involving 538 patients spanning over 4 years (2013-2016) at our dermatology indoor setup. Results There were 45 deaths (male:female = 1.5:1), accounting for 8.4% or total admissions, occurring mostly in patients in their 7th decade. Vesiculobullous disorders were the most frequent cause of mortality (57.8%), followed by drug reactions accounting for 17.8% of cases. In the former group pemphigus vulgaris accounted for most deaths (31.1%) followed by bullous pemphigoid (17.8%) and pemphigus foliaceus (8.9%), whereas toxic epidermal necrolysis was the most frequent cause of death from drug reactions (8.9%). Almost half of all deaths (48.9%) occurred due to septicemia followed by cardiopulmonary complications (40%). Most of the cases presented to us at an advanced state of the disease previously being treated inappropriately. Conclusion Prompt diagnosis and treatment of such dermatological conditions are mandated, preferably in an intensive care set-up, to reduce mortality rates. Advanced age, the area of skin involvement, mucosal involvement, and septicemia were adverse prognostic factors in these patients.

Abstract
BACKGROUND Extracorporeal treatments such as hemodialysis and plasma exchange are lifesaving measures in the treatment of drug poisoning. This treatment method generally is not used for severe cutaneous and systemic drug reactions. METHODS Here, we describe three cases wherein hemodialysis therapy was instrumental in reversing the adverse drug reaction. RESULTS In the cases of severe cutaneous drug reactions reviewed, patients presented with linear immunoglobulin A bullous dermatosis, acute generalized exanthematous pustulosis, and toxic epidermal necrolysis. Salvage treatment with hemodialysis therapy drastically influenced the course of disease, resulting in remission. CONCLUSIONS This novel and highly effective treatment option is not considered in current algorithms for adverse drug reactions. Hence, in addition to the rarity of these reactions, the main limitation of the study is the small number of patients. Hemodialysis can substantially alter the prognosis and, in some cases, be a lifesaving treatment for patients with severe adverse cutaneous drug reaction associated with systemic toxicity.

Abstract
INTRODUCTION Stevens Johnson Syndrome/toxic epidermal necrolysis (SJS/TEN) are rare, potentially fatal desquamative disorders characterised by large areas of partial thickness skin and mucosal loss. The degree of epidermal detachment that occurs has led to SJS/TEN being described as a burn-like condition. These patients benefit from judicious critical care, early debridement and meticulous wound care. This is best undertaken within a multidisciplinary setting led by clinicians experienced in the management of massive skin loss and its sequelae. In this study, we examined the clinical outcomes of SJS/TEN overlap & TEN patients managed by our regional burns service over a 12-year period. We present our treatment model for other burn centres treating SJS/TEN patients. METHODS A retrospective case review was performed for all patients with a clinical diagnosis of TEN or SJS/TEN overlap admitted to our paediatric and adult burns centre between June 2004 and December 2016. Patient demographics, percentage total body surface area (%TBSA), mucosal involvement, causation, severity of illness score (SCORTEN), length of stay and survival were appraised with appropriate statistical analysis performed using Graph Pad Prism 7.02 Software. RESULTS During the study period, 42 patients (M26; F: 16) with TEN (n=32) and SJS/TEN overlap (n=10) were managed within our burns service. Mean %TBSA of cutaneous involvement was 57% (range 10-100%) and mean length of stay (LOS) was 27 days (range 1-144 days). We observed 4 deaths in our series compared to 16 predicted by SCORTEN giving a standardised mortality ratio (SMR) of 24%. CONCLUSION Management in our burns service with an aggressive wound care protocol involving debridement of blistered epidermis and wound closure with synthetic and biological dressings seems to have produced benefits in mortality when compared to predicted outcomes.

Abstract
The terms 'lichenoid' and 'interface' dermatitis are often used interchangeably to describe an inflammatory pattern characterized histologically by damage to the basal keratinocytes in the epidermis. The mechanism of cell damage of such cells is now best understood as apoptosis, or programmed cell death. This inflammatory pattern of dermatoses, is also accompanied frequently by a band of lymphocytes and histiocytes in the superficial dermis, that often obscures the dermal-epidermal junction, hence the term 'lichenoid'. A discussion of the more common lichenoid/interface dermatitides encountered in the routine clinical practice encompasses the following entities: lichen planus, lupus erythematosus, dermatomyositis, erythema multiforme, graft versus host disease, fixed drug reactions, and multiple others.
