Toxic epidermal necrolysis following heart transplantation may caused by cefoperazone sodium and sulbactam sodium.

BACKGROUND: The outcome of heart transplantation is significantly affected by perioperative infections. Individualised immunosuppression strategies are essential to reduce the risk of such infections. CASE PRESENTATION: We report the successful management of a 56-year-old male patient diagnosed with dilated cardiomyopathy who underwent heart transplantation. During the perioperative period, the patient was prescribed cefoperazone sodium and sulbactam sodium, which induced a severe skin reaction: toxic epidermal necrolysis (TEN). The patient was treated with prednisone, immunoglobulins, etanercept, and other active immunomodulatory measures, together with an individualised anti-rejection regimen and physical therapy. The systemic rash resolved within a month, and the patient was successfully discharged after surgery. CONCLUSION: Effective management of heart transplantation necessitates balancing immunosuppression and infection prevention. Individualised immunosuppressive strategies are critical for optimal clinical outcomes.

A case report of Stevens-Johnson syndrome caused by omeprazole.

RATIONALE: Stevens-Johnson syndrome (SJS) is a rare but severe skin-mucosal reaction with a high mortality rate. It is characterized by sudden, painful blistering lesions on the skin, often accompanied by high fever and systemic toxicity. Lesions typically appear on the dorsal surfaces of the hands, feet, forearms, legs, and soles of the feet. They can also affect the conjunctiva, oral mucosa, labial mucosa, and vaginal mucosa. Patients may experience complications such as pneumonia, severe comorbidities, and liver and renal failure. PATIENT CONCERNS: A 51-year-old female patient was admitted to the hospital due to "abdominal distention and skin yellowing for 20 days." After using omeprazole, she developed a rash all over her body, and her liver function further deteriorated, ultimately leading to chronic acute liver failure. DIAGNOSES: The diagnosis included fever, rash suspected to be drug-induced, chronic and acute liver failure, and decompensation of post-Hepatitis B cirrhosis. INTERVENTIONS: During hospitalization, suspected adverse drug reactions were discontinued, and symptomatic supportive treatment with methylprednisolone and fluid replacement was promptly provided. OUTCOMES: The patient's symptoms and follow-up showed that the rash disappeared and liver and kidney function improved significantly after treatment. LESSONS: We explored how chronic acute liver failure can cause immune system abnormalities and immune paralysis in patients, manifested as susceptibility to infection. This case report describes a drug-induced allergic reaction - SJS - in patients with chronic acute liver failure, as well as subsequent treatment, including hormone dosage and treatment duration. I hope this report will help enrich the relevant literature on drug-induced SJS combined with chronic and acute liver failure, laying the foundation for improving the survival rate of patients with the disease.

Stevens-Johnson Syndrome/Toxic epidermal necrolysis complicated with fulminant type 1 diabetes mellitus: a case report and literature review.

BACKGROUND: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threatening skin lesion triggered by hypersensitive drug reaction. They are characterized by extensive epidermal necrosis and skin exfoliation. Fulminant type 1 diabetes mellitus (FT1DM) is featured by a rapid-onset of hyperglycemia with ketoacidosis due to severely destroyed ß-cell function. Fulminant type 1 diabetes mellitus as a sequela of SJS/TEN has rarely been reported. CASE PRESENTATION: We present a 73-year-old female patient who developed SJS/TEN skin allergic reaction after taking carbamazepine and phenytoin for 35 days. Then, hyperglycemia and diabetic ketoacidosis occurred 20 days after discontinuation of antiepileptic drugs. A very low serum C-peptide level (8.79 pmol/l) and a near-normal glycosylated hemoglobin level met the diagnostic criteria for fulminant T1DM. Intravenous immunoglobulin (IVIG) and insulin were promptly administered, and the patient recovered finally. CONCLUSIONS: This rare case indicates that monitoring blood glucose is necessary in SJS/TEN drug reaction, and comprehensive therapy with rehydration, insulin, antibiotics, and IVIG may improve the prognosis.

Steven-Johnson Syndrome/Toxic Epidermal Necrolysis is Associated with PD-1/PD-L1 Inhibitors Usage: A Case Series.

Aims/Background The increasing adoption of inhibitors of programmed cell death-1 (PD-1) and its ligand, programmed death-ligand 1 (PD-L1), in the treatment of multiple cancer types in China has started to garner broader attention due to the occurrence of immune-related adverse events (irAEs), especially life-threatening skin reactions such as Steven-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN). Isolated case reports have described SJS/TEN associated with PD-1/PD-L1 inhibitors usage. In this paper, we presented a series of cases of SJS/TEN following the use of PD-1/PD-L1 inhibitors in a dermatology hospital located in Zhejiang Province of China in the past several years, summarizing characteristics of these cases and providing a reference of management. Methods We retrospectively reviewed all the medical records of inpatients diagnosed with SJS/TEN in the Hangzhou Third People's Hospital from 2012 to 2024. We analyzed and compared the situation of SJS/TEN onset, types of PD-1/PD-L1 inhibitors used, score of severity, laboratory findings, and essential therapies of the patients who had received PD-1/PD-L1. Results We identified 12 SJS/TEN patients who had been treated with PD1/PD-L1 inhibitors: sintilimab had been used in six patients; tislelizumab in two cases; toripalimab, keytruda and cadonilimab each in one case; and an unknown prescription in one case. The longest duration between the first PD-1/PD-L1 inhibitor dose and the SJS/TEN diagnosis recorded was nine months whereas the shortest was 11 days. Half of the selected patients received chemotherapy at the same time. More than two types of therapies were applied to the cases, except for two cases with mild SJS. Conclusion This study unveils a potential, under-recognized cause of SJS/TEN in the cancer patients after analyzing the cases of SJS/TEN in cancer patients with prior exposure to PD-1/PD-L1 inhibitors. This paper also provides clue about the prominent features of SJS/TEN aforesaid, offering insights on the effective management measures for optimizing clinical safety.

Antibiotic-induced severe cutaneous adverse reactions: a single-center retrospective study over ten years.

Objective: Severe cutaneous adverse reactions (SCARs) are rare but life-threatening, with antibiotics being the main cause. This retrospective study from a single center was designed to analyze the culprit drugs, clinical features and treatment outcomes of antibiotic-induced SCARs. Methods: We analyzed cases of antibiotic-induced SCARs in a tertiary hospital in China between January 2013 and January 2024, including Steven-Johnson syndrome (SJS) or Stevens-Johnson syndrome-toxic epidermal necrolysis (SJS-TEN) overlap, toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS) and acute generalized exanthematous pustulosis (AGEP). Descriptive analysis of the demographic characteristics, clinical manifestations, treatment and prognosis were carried out. Results: Among 354 cases of SCARs, 63 validated antibiotic-related cases were included. Cephalosporins (31.7%), penicillins (25.4%), and quinolones (19.0%) were the most common triggers for SCARs. Overall, liver (50.8%), lungs (31.7%), and kidneys (23.8%) were the most frequently affected organ in SCARs cases. Eight patients (28.6%) in the SJS/SJS-TEN overlap group and 8 patients (80.0%) in the TEN group received combination therapy of corticosteroids and IVIG. Patients with SCARs caused by penicillins or cephalosporins could receive alternative treatments such as lincomamides, quinolones, and tetracyclines. The mortality rate in the TEN group was the highest at 20.0%, followed by the SJS/SJS-TEN overlap group (7.1%), and no deaths were observed in the DRESS and AGEP groups. Conclusion: The identification of the culprit antibiotics and the application of alternative antibiotic therapies are crucial for the management of antibiotic-induced SCARs. If complicated underlying conditions and complications like advanced age, cancer and pneumonia coexist with SCARs, patients might be more at risk for mortality.

Tumor necrosis factor inhibitors enhance corticosteroid therapy for Stevens-Johnson syndrome and toxic epidermal necrolysis linked to immune checkpoint inhibitors: a prospective study.

Introduction: Immune-related epidermal necrolysis (irEN), including Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN), represents a potentially lethal reaction to immune checkpoint inhibitors. An optimal treatment strategy remains undefined. This study evaluates the effectiveness and safety of combination therapy with corticosteroids and tumor necrosis factor inhibitors (TNFi) in treating irEN patients. Methods: In this single-center, prospective, observational study, patients with irEN received either corticosteroid monotherapy or a combination therapy of corticosteroids and TNFi (etanercept for SJS, infliximab for TEN). The primary endpoint was re-epithelization time, with secondary endpoints including corticosteroid exposure, major adverse event incidence, acute mortality rates, and biomarkers indicating disease activity and prognosis. The study was registered at the Chinese Clinical Trial Registry (ChiCTR2100051052). Results: Thirty-two patients were enrolled (21 SJS, 11 TEN); 14 received combination therapy and 18 received corticosteroid monotherapy. IrEN typically occurred after 1 cycle of ICI administration, with a median latency of 16 days. Despite higher SCORTEN scores in the combination group (3 vs. 2, p = 0.008), these patients experienced faster re-epithelization (14 vs. 21 days; p < 0.001), shorter corticosteroid treatment duration (22 vs. 32 days; p = 0.005), and lower prednisone cumulative dose (1177 mg vs. 1594 mg; p = 0.073). Major adverse event rates were similar between groups. Three deaths occurred due to lung infection or disseminated intravascular coagulation, with mortality rates for both groups lower than predicted. Potential risk factors for increased mortality included continuous reduction in lymphocyte subset counts (CD4+ T cells, CD8+ T cells, natural killer cells) and consistent rises in inflammatory markers (serum ferritin, interleukin-6, TNF-α). Re-epithelization time negatively correlated with body mass index and positively correlated with epidermal detachment area and serum levels of interleukin-6 and TNF-α. Conclusions: Corticosteroids combined with TNFi markedly promote re-epithelization, reduce corticosteroid use, and decrease acute mortality in irEN patients without increasing major adverse events, offering a superior alternative to corticosteroid monotherapy. Inflammatory markers and lymphocyte subsets are valuable for assessing disease activity and prognosis.

Generalized Fixed Drug Eruptions Require Urgent Care: A Case Series.

A generalized fixed drug eruption (FDE) is an uncommon but potentially dangerous reaction to medication. In this case series, we present 1 patient with a generalized FDE and 2 patients with generalized bullous FDE that resolved with cyclosporine, though 1 patient required close monitoring in the intensive care unit. Immediate acceleration of care upon development and recognition of generalized bullous FDE is essential, as the mortality rate is similar to Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN).

Moderate and serious adverse reactions to antimicrobials among hospitalized children: A systematic review.

AIMS: This systematic review aimed to investigate the occurrence of moderate and severe adverse drug reactions (ADRs) to antimicrobials among hospitalized children. METHODS: The PubMed/Medline, Cochrane Library, Embase, Web of Science, Scopus, Lilacs and CINAHL databases were searched in April 2023 to systematically review the published data describing the characteristics of moderate and severe ADRs to antimicrobials among hospitalized children. The search was carried out without date restrictions, up to the search date (April, 2023). RESULTS: At the end of the selection process, 30 articles met the inclusion criteria. Cutaneous reactions were the primary serious clinical manifestations in most articles (19/30), followed by erythema multiforme (71 cases), Stevens-Johnson syndrome (72 cases), and toxic epidermal necrolysis (22 cases). The main antimicrobials involved in moderate and severe ADRs were penicillins, cephalosporins and sulfonamides. Regarding the primary outcomes, 30% (9/30) of the articles reported deaths, and 46.7% (14/30) of studies reported increased lengths of hospital stay, need for intensive care, and transfer to another hospital. Regarding the main interventions, 10% (3/30) of the articles mentioned greater monitoring, suspension, medication substitution or prescription of specific medications for the symptomatology. CONCLUSIONS: The findings of this review could be used to identify areas for improvement and help health professionals and policymakers develop strategies. In addition, we emphasize the importance of knowing about ADRs so that there is adequate management to avoid undesirable consequences.

Life-threatening Rash Due to Lamotrigine and a Failure to Understand Its Pharmacology: How Forensic Detective Work Uses Medical Knowledge and Clinical Pharmacology to Solve Cases.

This column is the second of a 3-part series describing cases where general medical knowledge, including psychiatric and clinical pharmacology, were instrumental in determining dereliction and direct cause in a malpractice suit. This case summarizes how lamotrigine can cause dangerous consequences if its pharmacology is not properly understood. The case also illustrates how the 4 Ds of a forensic malpractice suit were met in this case. First, there was duty on the part of the prescriber which, if followed, would have prevented or minimized the damages experienced by the patient. Dereliction in the performance of a patient-physician treatment contract was a direct cause of the development of Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) in this patient. An immune-mediated reaction to lamotrigine or one of its metabolites has been extensively reported in the literature, with the risk of this reaction increasing at higher doses and with more rapid titration, fulfilling the elements of direct cause. Dereliction implies a deviation from the standard of care. On the basis of the clinical information from the package insert, more likely than not a deviation from the standard of care occurred in this case when lamotrigine was titrated faster than recommended by the package insert.

Methotrexate might become the sole treatment option for leukemia following the occurrence of Stevens-Johnson syndrome.

INTRODUCTION: Severe cutaneous adverse reactions (SCARs) arising from drug interactions can carry life-threatening implications and result in lasting effects. SCARs can be triggered by various factors, with trimethoprim/sulfamethoxazole identified as a primary culprit. Anticonvulsants and antineoplastic agents have been noted as secondary triggers. Notably, antineoplastics linked to SCARs include immunomodulatory agents. The higher mortality rates among cancer patients with SCARs underscore the significance of comprehending cancer--specific risk factors. Our objective is to present the case of a boy with acute lymphocytic leukemia (ALL) who developed Stevens-Johnson syndrome (SJS) following MTX treatment. CASE REPORT: We present the case of a three-year-old male patient diagnosed with ALL who developed Stevens-Johnson syndrome (SJS) subsequent to the administration of MTX, following the "BFM 2009" protocol. He had undergone intrathecal MTX administration on six previous occasions. Our patient received IVIG at a dose of 2g/kg along with steroids, resulting in partial clinical improvement after 21 days. An innovative protocol was developed, involving IVIG before MTX infusion and dexamethasone before MTXi, with folinic acid rescue. Intravenous immunoglobulin (IVIG) mitigates SJS/TEN via type IV hypersensitivity down-regulation and apoptosis curbing. CONCLUSION: As far as we know, the prophylactic use of IVIG to counteract SCARs in a pediatric leukemia patient represents uncharted territory. Moreover, research into the immune system dynamics within these patients and the preservation of indispensable treatments should involve allergist-immunologists as part of the multidisciplinary team attending to neoplastic conditions.

Stevens-Johnson syndrome-toxic epidermal necrolysis overlap in a patient taking quetiapine and famotidine: a case report.

BACKGROUND: Stevens-Johnson syndrome-toxic epidermal necrolysis (SJS-TNE) overlap is a rare skin disorder characterized by erythema, blisters, extensive exfoliation, epidermal detachment, the involvement of multiple mucosae, and positive Nikolsky's sign. SJS-TEN has a high mortality rate. Our case involves a rare occurrence of drug-induced Stevens-Johnson syndrome-toxic epidermal necrolysis overlap with a delayed onset in the setting of quetiapine and famotidine therapy. CASE PRESENTATION: An 82-year-old Taiwanese female was admitted to our hospital for decreased urine output, generalized edema, and multiple skin blisters and bedsores. With further spread of the lesions, multiple ruptured bullae with shallow erosions on the face, trunk, and limbs and mucosal involvement affected 20% of the total body surface area. Nikolsky's sign was positive. A diagnosis of Steven-Johnson syndrome was highly suspected. One month prior, she had started famotidine and quetiapine. Intravenous methylprednisolone treatment was initiated, which ameliorated the skin lesions after 3 days. However, new lesions developed after only 1 day of methylprednisolone tapering. The patient died 12 days after admission. CONCLUSION: Stevens-Johnson syndrome-toxic epidermal necrolysis is a rare skin disorder. Although it is mainly acute and has a high mortality rate, delayed onset can still occur. Quetiapine and famotidine are generally safe and effective for treating geriatric and gastrointestinal problems, but rare drug hypersensitivity reactions can lead to debilitating consequences. Therefore, increased clinical awareness and the initiation of supportive care are imperative. Optimal management guidelines are still lacking, and confirmation of developed guidelines through randomized controlled trials is needed. Collaboration for better management strategies is warranted.

Stevens-Johnson syndrome and toxic epidermal necrolysis associated with immune checkpoint inhibitors: a systematic review.

Introduction: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare yet life-threatening adverse events associated with immune checkpoint inhibitors (ICIs). This systematic review synthesizes the current literature to elucidate the clinical characteristics and outcomes of patients with ICI-related SJS/TEN. Methods: We conducted a thorough search across databases including Embase, Web of Science, Cochrane, MEDLINE, Scopus, and PubMed. Selection criteria focused on reports of SJS/TEN among cancer patients treated with ICIs, analyzing clinical manifestations, therapeutic interventions, and outcomes. Results: Our analysis included 47 articles involving 50 patients with ICI-related SJS/TEN. The cohort had a mean age of 63 years, with a slight male predominance (54%). Most patients had melanoma or non-small cell lung cancer. SJS/TEN typically occurred early, with a median onset of 23 days post-ICI initiation. Treatment primarily involved systemic corticosteroids and intravenous immunoglobulins. The overall mortality rate was 20%, higher for TEN at 32%, with infections and tumor progression as leading causes. Median time from onset to death was 28 days. Survivors experienced a median re-epithelization time of 30 days, positively correlated with the extent of epidermal detachment (rs = 0.639, p = 0.009). Deceased patients exhibited a significantly higher proportion of TEN (90% vs. 48%, p = 0.029) and a larger epidermal detachment area (90% vs. 30% of the body surface area [BSA], p = 0.005) compared to survivors. The combination therapy group showed a higher proportion of TEN compared to corticosteroid monotherapy or non-corticosteroid therapy groups (72% vs. 29% and 50%, p = 0.01), with no significant differences in mortality or re-epithelization time. Dual ICI therapy resulted in a higher TEN rate than single therapy (100% vs. 50%, p = 0.028). Among single ICI therapies, the sintilimab-treated group trended towards a higher TEN rate (75% vs. 40-50%, p = 0.417), a larger detachment area (90% vs. 30-48% of BSA, p = 0.172), and a longer re-epithelization time (44 vs. 14-28 days, p = 0.036) compared to other ICI groups, while mortality rates remained similar. Conclusion: ICI-related SJS/TEN substantially impacts patient outcomes. Prospective clinical trials are critically needed to further clarify the pathogenesis and optimize therapeutic regimens.

Pyrazinamide-induced Toxic Epidermal Necrolysis.

The antitubercular drugs are associated with different cutaneous adverse drug reactions. Toxic epidermal necrolysis (TEN) is a severe form of cutaneous reaction. Although it is rare, it carries a high mortality rate. We report a case of a 75-year-old man with abdominal tuberculosis, who developed pyrazinamide-induced TEN.

RésuméLes médicaments antituberculeux sont associés à différents effets indésirables cutanés. La nécrolyse épidermique toxique (TEN) est une forme sévère de réaction cutanée. Bien qu'elle soit rare, elle entraîne un taux de mortalité élevé. Nous rapportons le cas d'un homme de 75 ans atteint de tuberculose abdominale, qui ont développé un TEN induit par le pyrazinamide.

[The overlap Stevens-Johnson syndrome due to meropenem administration. Clinical case and nursing care]. / Sindrome da overlap di Stevens-Johnson causata dalla somministrazione di meropenem. Descrizione clinica e trattamento infermieristico.

. The overlap Stevens-Johnson syndrome due to meropenem administration. Clinical case and nursing care. A case of overlap Stevens-Johnson syndrome caused by meropenem administration is described. It is a rare cutaneous reaction due to delayed hypersensitivity to drugs characterised by the destruction and separation of the skin epithelium and mucous membranes, affecting between 10% and 29% of the body surface area. The clinical description of the case and a detailed description of nursing management and interventions based on the available literature are reported.

Paraneoplastic dermatomyositis and Stevens-Johnson syndrome related to immunotherapy.

Paraneoplastic syndromes such as dermatomyositis, often emerge as the initial clinical manifestation across various cancer types and are characterized by the development of B-cell responses targeting cancer-cell antigens that cross-react with normal skin and muscle cells. While these syndromes may alleviate following antineoplastic intervention, their response to immunotherapy remains elusive due to the exclusion of patients with autoimmune phenomena from clinical trials. In this report, we present the case of a female patient with advanced urothelial cancer presenting with dermatomyositis, who subsequently underwent treatment with anti-PD1 immunotherapy and experienced the onset of Stevens-Johnson syndrome. We discuss these two autoimmune entities and provide a comprehensive review of the existing literature to elucidate similar associations.

Dermatomyositis, an inflammatory disorder that causes a skin rash, might be the first sign that someone has cancer. But when scientists test new cancer treatments, they often don't include people with this skin problem. So, we do not know much about how safe or effective these treatments are for them. Here's a story about someone who had bladder cancer and dermatomyositis. They received a treatment called immunotherapy, but it caused a serious problem called Stevens-Johnson syndrome. We also found similar cases in medical papers.

Antiepileptic Medication-induced Severe Cutaneous Adverse Reactions in Hospitalized Children: A Retrospective Study.

BACKGROUND: There are limited data on severe cutaneous adverse reactions (SCARs) associated with antiepileptic medications. The current study aims to investigate the clinical and epidemiological characteristics of antiepileptic medication-induced SCARs in hospitalized children. MATERIALS AND METHODS: The current five-year retrospective study was conducted at Isfahan University of Medical Sciences, Iran. This study included all children with a definite diagnosis of SCARs secondary to the use of antiepileptic medications based on the world health organization (WHO) definition. In our study SCARs were categorized into three fields: Hypersensitivity syndrome, drug reaction with eosinophilia and systemic symptoms (DRESS), and Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN). RESULTS: Among 259 children with SCARs induced by antiepileptic medications, 199 (76.83%), 42 (16.22%), and 18 (6.95%) had hypersensitivity syndrome, DRESS, and SJS/TEN, respectively. Phenobarbital was the most common offending drug in all types of SCARs. The multinomial logistic regression model revealed that lymphadenopathy increased the occurrence of DRESS by 35 times compared to hypersensitivity syndrome (P < 0.001). Girls were at risk of SJS/TEN approximately 6 times more than boys (P = 0.027). Age (P = 0.021), weight (P = 0.036), and mucosal involvement (P < 0.001) affected the hospitalization duration in children with SCARs related to antiepileptic medication. CONCLUSION: There are some similarities and differences in the clinical and epidemiological features of Iranian children suffering from antiepileptic medication-induced SCARs.
