Abstract
Chikungunya is a viral disease transmitted by female Aedes mosquitoes that has been increasingly reported in many parts of the world across the geographical borders. In addition to fever and joint pain, mucocutaneous manifestations of chikungunya have been reported in 40-75% of infected patients. Dermatological manifestations of chikungunya are often under-recognized and misdiagnosed as clinicians are not sensitized or educated regarding these. The early-onset cutaneous manifestations of chikungunya fever, occurring within 1 month of the fever, include maculopapular rashes, vesiculobullous eruptions, Steven-Johnson syndrome/toxic epidermal necrolysis-like eruptions, flagellate lesions, scrotal dermatitis, oro-genital ulcers, and exacerbation of preexisting dermatoses like psoriasis. Hyperpigmentation, lichenoid eruptions, diffuse hair fall, and exacerbation of acne usually occur as a late manifestation. Diagnosis of these mucocutaneous manifestations can be challenging as they often resemble other common dermatoses. This review article elaborates on various mucocutaneous manifestations of chikungunya fever, based on literature review and authors' clinical experience.

Abstract
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe dermatological emergencies. The role of cytokines and chemokines in the pathogenesis, progression of the disease, and histopathologic features is not fully elucidated. To address this gap, we conducted a retrospective study examining the associations between 42 serum biomarkers, histopathologic findings, and clinical outcomes in SJS/TEN patients. We reviewed the medical records of 23 patients diagnosed with SJS/TEN. Regarding histopathology, our study did not reveal any significant associations between the degree of epidermal necrosis, dermal mononuclear cell infiltration, and clinical outcomes. However, an intriguing observation was made regarding the degree of dermal infiltration of CD8 + cells, which showed a negative correlation with the severity of acute ocular complications. Notably, serum levels of IFN-γ positively correlated with the number of CD8 + cells in dermal infiltration. Additionally, higher serum levels of myeloperoxidase were associated with greater degrees of epidermal necrosis, while serum Fas ligand and stem cell factor levels were elevated in individuals with increased dermal mononuclear cell infiltration. Furthermore, the levels of S100A8/A9 were significantly correlated with the SCORTEN and mortality rate. These findings provide insights into the intricate pathogenesis of the disease.

Abstract
Importance Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) are severe cutaneous adverse reactions, and patients with SJS/TEN frequently require intensive care. However, there is limited evidence on the clinical outcomes of immunomodulating therapy, including plasmapheresis and intravenous immunoglobulin (IVIG) in patients with SJS/TEN. Objective To compare clinical outcomes of patients with SJS/TEN who were treated with plasmapheresis first vs IVIG first after ineffective systemic corticosteroid therapy. Design, Setting, and Participants This retrospective cohort study used data from a national administrative claims database in Japan that included more than 1200 hospitals and was conducted from July 2010 to March 2019. Inpatients with SJS/TEN who received plasmapheresis and/or IVIG therapy after initiation of at least 1000 mg/d of methylprednisolone equivalent systemic corticosteroid therapy within 3 days of hospitalization were included. Data were analyzed from October 2020 to May 2021. Exposures Patients who received IVIG or plasmapheresis therapy within 5 days after initiation of systemic corticosteroid therapy were included in the IVIG- and plasmapheresis-first groups, respectively. Main Outcomes and Measures In-hospital mortality, length of hospital stay, and medical costs. Results Of 1215 patients with SJS/TEN who had received at least 1000 mg/d of methylprednisolone equivalent within 3 days of hospitalization, 53 and 213 patients (mean [SD] age, 56.7 [20.2] years; 152 [57.1%] women) were included in the plasmapheresis- and IVIG-first groups, respectively. Propensity-score overlap weighting showed no significant difference in inpatient mortality rates between the plasmapheresis- and IVIG-first groups (18.3% vs 19.5%; odds ratio, 0.93; 95% CI, 0.38-2.23; P = .86). Compared with the IVIG-first group, the plasmapheresis-first group had a longer hospital stay (45.3 vs 32.8 days; difference, 12.5 days; 95% CI, 0.4-24.5 d; P = .04) and higher medical costs (US $34 262 vs $23 054; difference, US $11 207; 95% CI, $2789-$19 626; P = .009). Conclusions and Relevance This nationwide retrospective cohort study found no significant benefit to administering plasmapheresis therapy first instead of IVIG first after ineffective systemic corticosteroid treatment in patients with SJS/TEN. However, medical costs and length of hospital stay were greater for the plasmapheresis-first group.

Reactive infectious mucocutaneous eruption due to COVID-19 with erythema-multiforme-like lesions and myeloid cells. J Cutan Pathol 2023; 50:321-325. [PMID: 36194075 PMCID: PMC9874869 DOI: 10.1111/cup.14339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 09/06/2022] [Accepted: 10/03/2022] [Indexed: 01/27/2023]
Abstract
Reactive infectious mucocutaneous eruption (RIME) is a recently described entity in which there is prominent mucositis, most commonly involving the oral and urogenital mucosa, secondary to a variety of pathogens. There is typically minimal cutaneous involvement in RIME. This contrasts with erythema multiforme (EM) in which characteristic targetoid lesions predominate, usually in isolation (EM minor), but in a subset of cases, with severe mucositis (EM major). While the histopathologic features of RIME have not been as well defined, those of EM are characterized by epidermal apoptosis and interface dermatitis with lymphocytes making up the predominant cell type. We report a unique case of RIME in a 16-year-old male with COVID-19 characterized by significant mucositis involving the oral and genital mucosa, as well as numerous targetoid lesions on the trunk and extremities. Histopathologically, there was an inflammatory infiltrate obscuring and disrupting the epidermal interface, associated with epidermal necrosis, and blister formation. The infiltrate was composed of cells with irregular, non-segmented and elongate nuclei, with myeloid and histiocytoid cytomorphology. The cells were positive for myeloperoxidase, CD68, and CD163 (subset) suggesting myeloid lineage. RIME is a rarely reported COVID-19-related eruption, and targetoid lesions and myeloid interface reactions have not been described with RIME.

Abstract
Publication bias may lead to a misestimation in the association between pharmacogenetic biomarkers (PGx) and antiseizure drug's adverse effects (AEs). We aimed to assess its prevalence in this field. We searched for systematic reviews assessing PGx of antiseizure drug's AEs. For each unique association between a PGx, a drug and its AE, we used the available odds ratio (ORs) to generate corresponding funnel plots. We estimated the prevalence of publication bias using visual inspections and asymmetry tests. We explored the impact of publication bias using ORs adjusted for potential publication bias. Twenty-two associations were available. Our visual analysis suggested a publication bias in five out twenty-two funnel plots (23% [95%CI: 8; 45]). The Egger's test showed a significant publication bias in one (HLA-B*15:02 and phenytoin-induced Stevens-Johnson syndrome or toxic epidermal necrolysis, p = 0.03) out of nine (11% [95%CI: 0; 48]) and the Begg's test in one (HLA-B*15:02 and carbamazepine-induced serious cutaneous reactions, p = 0.02) out of ten (10% [95%CI: 0; 45]) assessable funnel plots. Adjusting for publication bias may reduce by half the ORs of the pharmacogenetics associations. Publication bias in the pharmacogenetic of antiseizure drug's AEs is not uncommon and may affect the estimation of the effect of such biomarkers. When conducting pharmacogenetic studies, it is critical to publish also the negative one.

Abstract
Nivolumab is an immune checkpoint inhibitor acting on programmed cell death protein 1 (PD-1) that has been used to treat a growing number of malignancies. Cutaneous side effects are common with nivolumab treatment, though they are typically self-limited. Here we present a case of persistent lichenoid dermatitis in a patient treated with nivolumab for renal cell cancer. The patient then developed Stevens-Johnson syndrome 9 months after initiation of nivolumab, with no other identifiable offending medication in the interim. Although an unusual presentation, a growing number of cases have reported delayed Stevens-Johnson syndrome/toxic epidermolytic necrosis-like reactions to immune checkpoint inhibitors. Awareness of this phenomenon is imperative for prompt recognition and treatment of potentially life-threatening cutaneous side effects.

Abstract
A 52-year-old male presented to Beijing Tongren Hospital with a 5-year history of bilateral dry eyes. He had been diagnosed with Steven-Johnson syndrome due to allergy to cold medication. On examination, the Schirmer I test value was 0 mm, the tear break-up time was 0 s, and corneal fluorescein staining showed corneal epithelial erosion with partial fusion in both eyes. The clinical diagnosis was dry eyes (severe) and Steven-Johnson syndrome. No significant effect was observed after use of artificial tears and anti-inflammatory eye drops and tear punctal embolization. Then an insular infraorbital neurovascular pedicle labial salivary gland transplantation was performed in the right eye. During the 1-year postoperative follow-up, the symptoms and signs were significantly improved in the operated eye, and the surgical results were satisfactory. (Chin J Ophthalmol, 2021, 57: 946-948).

Abstract
OBJECTIVES Earlier diagnosis and the best management of virus-related, drug-related or mixed severe potentially life-threatening mucocutaneous reactions of COVID-19 patients are of great concern. These patients, especially hospitalised cases, are usually in a complicated situation (because of multi-organ failures), which makes their management more challenging. In such consultant cases, achieving by the definite beneficial management strategies that therapeutically address all concurrent comorbidities are really hard to reach or even frequently impossible. METHODS According to the lack of any relevant systematic review, we thoroughly searched the databases until 5 October 2020 and finally found 57 articles including 93 patients. It is needed to know clinical presentations of these severe skin eruptions, signs and symptoms of COVID in these patients, time of skin rash appearance, classifying drug-related or virus-related skin lesions, classifying the type of skin rash, patients' outcome and concurrent both COVID-19 therapy and skin rash treatment. RESULT Severe and potential life-threatening mucocutaneous dermatologic manifestations of COVID-19 usually may be divided into three major categories: virus-associated, drug-associated, and those with uncertainty about the exact origin. Angioedema, vascular lesions, toxic shock syndrome, erythroderma, DRESS, haemorrhagic bulla, AGEP, EM, SJS and TEN, generalised pustular figurate erythema were the main entities found as severe dermatologic reactions in all categories. CONCLUSION We can conclude vascular injuries may be the most common cause of severe dermatologic manifestations of COVID-19, which is concordant with many proposed hypercoagulation tendencies and systemic inflammatory response syndrome as one of the most important pathomechanisms of COVID-19 so the skin may show these features in various presentations and degrees.

Abstract
PURPOSE OF REVIEW An update of the pharmacogenetic risk factors associated with T-cell-mediated delayed hypersensitivity reactions. RECENT FINDINGS Recent HLA associations relevant to our understanding of immunopathogenesis and clinical practice include HLA-B∗13:01 with co-trimoxazole-induced SCAR, and HLA-A∗32:01 with vancomycin-DRESS, for which an extended HLA class II haplotype is implicated in glycopeptide antibiotic cross-reactivity. Hypoactive variants of ERAP1, an enzyme-trimming peptide prior to HLA loading, are now associated with protection from abacavir-hypersensitivity in HLA-B∗57:01+ patients, and single-cell sequencing has defined the skin-restricted expansion of a single, public and drug-reactive dominant TCR across patients with HLA-B∗15:02-restricted carbamazepine-induced SJS/TEN. More recent strategies for the use of HLA and other risk factors may include risk-stratification, early diagnosis, and diagnosis in addition to screening. SUMMARY HLA is necessary but insufficient as a risk factor for the development of most T-cell-mediated reactions. Newly emerged genetic and ecological risk factors, combined with HLA-restricted response, align with underlying immunopathogenesis and drive towards enhanced strategies to improve positive-predictive and negative-predictive values. With large population-matched cohorts, genetic studies typically focus on populations that have been readily accessible to research studies, but it is now imperative to address similar risk in globally relevant and understudied populations.

Abstract
PURPOSE To evaluate the effect of systemic cyclosporine (CsA) on ocular disease in Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) patients. METHODS In this retrospective, comparative cohort study at a single center, patients with a diagnosis of SJS/TEN and with at least 3 months of follow up were divided into two groups: those who received systemic CsA and those who did not receive systemic CsA. Best-corrected visual acuity (BCVA) and chronic ocular surface complications score (COCS) at final follow-up were compared between the two groups. RESULTS The median age and follow-up period of patients was 29 years (range, 1.5-71 years) and 16.8 months (range, 3.67-91.58 months), respectively. BCVA, COCS, meibomian gland dysfunction, limbal stem cell deficiency, and the need for mucous membrane grafting and scleral lenses were not significantly different between patients who received systemic CsA as compared to patients who did not receive systemic CsA. CONCLUSIONS In this small cohort of patients with SJS/TEN, we could identify no association between the use of systemic CsA as a component of their initial therapy and chronic ocular complications.

Abstract
OBJECTIVE The aim: To determine a possible role of nitric oxide system as one of the pathogenesis links in Stevens-Johnson syndrome depending on the severity of disease progression. PATIENTS AND METHODS Material and methods: We examined 11 patients with Stevens-Johnson syndrome. The function of nitric oxide system (NO - NOS) in blood serum was examined. RESULTS Results: During the study of nitric oxide system (NO-NOS) in patients with SJS, it was observed that NO2¯ level was increased by 1.53 times, NO3¯ level - by 3.33 times, activity of total NOS - by 5.78 times, constitutive (cNOS) - by 1.81 times and inducible (iNOS) - by 13.36 times. CONCLUSION Conclusions: The intensity of nitric oxide system function was studied in patients with Stevens-Johnson syndrome and dependence of changes of its parameters from the clinical signs of disease was detected. It was found that the determination of nitrite and nitrate anion levels in blood serum can be used for the purpose of predicting the disease course and choosing the therapy methods for the patients with SJS.

Severe Delayed Cutaneous and Systemic Reactions to Drugs: A Global Perspective on the Science and Art of Current Practice. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2017; 5:547-563.

Abstract
Most immune-mediated adverse drug reactions (IM-ADRs) involve the skin, and many have additional systemic features. Severe cutaneous adverse drug reactions (SCARs) are an uncommon, potentially life-threatening, and challenging subgroup of IM-ADRs with diverse clinical phenotypes, mechanisms, and offending drugs. T-cell-mediated immunopathology is central to these severe delayed reactions, but effector cells and cytokines differ by clinical phenotype. Strong HLA-gene associations have been elucidated for specific drug-SCAR IM-ADRs such as Stevens-Johnson syndrome/toxic epidermal necrolysis, although the mechanisms by which carriage of a specific HLA allele is necessary but not sufficient for the development of many IM-ADRs is still being defined. SCAR management is complicated by substantial short- and long-term morbidity/mortality and the potential need to treat ongoing comorbid disease with related medications. Multidisciplinary specialist teams at experienced units should care for patients. In the setting of SCAR, patient outcomes as well as preventive, diagnostic, treatment, and management approaches are often not generalizable, but rather context specific, driven by population HLA-genetics, the pharmacology and genetic risk factors of the implicated drug, severity of underlying comorbid disease necessitating ongoing treatments, and cost considerations. In this review, we update the basic and clinical science of SCAR diagnosis and management.

The Importance of Patient-Specific Factors for Hepatic Drug Response and Toxicity. Int J Mol Sci 2016; 17:E1714. [PMID: 27754327 PMCID: PMC5085745 DOI: 10.3390/ijms17101714] [Citation(s) in RCA: 62] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2016] [Revised: 09/23/2016] [Accepted: 09/27/2016] [Indexed: 02/07/2023] Open
Abstract
Responses to drugs and pharmacological treatments differ considerably between individuals. Importantly, only 50%-75% of patients have been shown to react adequately to pharmacological interventions, whereas the others experience either a lack of efficacy or suffer from adverse events. The liver is of central importance in the metabolism of most drugs. Because of this exposed status, hepatotoxicity is amongst the most common adverse drug reactions and hepatic liabilities are the most prevalent reason for the termination of development programs of novel drug candidates. In recent years, more and more factors were unveiled that shape hepatic drug responses and thus underlie the observed inter-individual variability. In this review, we provide a comprehensive overview of different principle mechanisms of drug hepatotoxicity and illustrate how patient-specific factors, such as genetic, physiological and environmental factors, can shape drug responses. Furthermore, we highlight other parameters, such as concomitantly prescribed medications or liver diseases and how they modulate drug toxicity, pharmacokinetics and dynamics. Finally, we discuss recent progress in the field of in vitro toxicity models and evaluate their utility in reflecting patient-specific factors to study inter-individual differences in drug response and toxicity, as this understanding is necessary to pave the way for a patient-adjusted medicine.

Abstract
Our purpose is to comprehensively review the state of the art with regard to Stevens- Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), with particular attention to improving the management of associated ocular surface complications. SJS and TEN are two ends of a spectrum of immune-mediated disease, characterized in the acute phase by a febrile illness followed by skin and mucous membrane necrosis and detachment. Part I of this review focused on the systemic aspects of SJS/TEN and was published in the January 2016 issue of this journal. The purpose of Part II is to summarize the ocular manifestations and their management through all phases of SJS/TEN, from acute to chronic. We hope this effort will assist ophthalmologists in their management of SJS/TEN, so that patients with this complex and debilitating disease receive the best possible care and experience the most optimal outcomes in their vision and quality of life.

Abstract
Stevens-Johnson syndrome (SJS) is a severe skin and mucosal condition, with eruption of hemorrhagic vesiculous to bullous lesions, caused by hypersensitive reaction to certain drugs; rarely, it can be parainfectious. SJS is a minor form of toxic epidermal necrolysis, with involvement of less than 10 % of the skin surface. Cutaneous and mucosal lesions are caused by necrosis of epithelial cells induced by T lymphocytes. The diagnosis is based on clinical features but it has to be confirmed by histologic and immunohistologic examination of the lesions. The treatment consists of high doses of systemic corticosteroids and particularly thorough local, supportive and symptomatic therapy. The authors present a case of parainfectious SJS and discuss the latest knowledge about SJS as well as therapeutic options.

A clinical approach to pharmacogenetics. Neth J Med 2013; 71:145-152. [PMID: 23712814] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 06/02/2023]
Abstract
Taking into account the high frequency of adverse drug reactions (ADRs) in the clinic and taking into account the growing knowledge of the genetic mechanisms underlying some of these ADRs, we believe that every clinician should know at least the basic principles of pharmacogenetics. However, our experience is that many clinicians are unaware of the potential contribution of pharmacogenetic testing and have not implemented this new modality in their daily practice. We present a case of Stevens-Johnson syndrome in a patient treated with carbamazepine. Following the pathways of clinical reasoning, we describe the possibilities of pharmacogenetic testing in the clinic (HLA-B*1502 and HLA-A*3101 in our patient). We describe the pharmacological and pharmacogenetic aspects relevant for the clinician's daily practice (the existence of ADR subtypes, cytochrome P450, drug-drug interactions, genetic variations, CYP450 and HLA genotyping). Based on the Dutch top 100 of most prescribed drugs, we provide data on CYP450 and HLA genotypes relevant to those 100 most commonly used drugs. We discuss the availability and costs of pharmacogenetic testing, show a calculation of the 'number needed to genotype' and, based on these data, we propose a decision model for pharmacogenetic testing by clinicians.

Abstract
UNLABELLED We describe an affordable, easily available technique to relieve discomfort, free the eyeball and partially rehabilitate a patient with ocular complications of end stage Stevens Johnson syndrome. MATERIAL AND METHODS Two eyes of a patient with severe adhesions between the lids, bulbar conjunctiva and cornea were involved. After taking consent from patient, the adhesions were separated and the fornices were dressed with sofratulle and artificial lubricants until healing was complete. DISCUSSION The separation of the lids from the globe and prevention of contact between the ocular surface and tarsal conjunctiva until both are healed by sofratulle and lubricants happens to be the only choice in our environment without material and human resources for complex procedures such as submandibular autotransplantation, osteo-odonto keratoprosthesis and modified cutler beard flap. The use of amniotic membrane transplantation (AMT) was also not feasible at that time. RESULTS The visual acuity was hand movement in both eyes, the lids were free and the eyes remained freely mobile four weeks after surgery. CONCLUSION In an environment with little resources, our procedure is recommended for use as an initial procedure pending final rehabilitative surgery, as it is easily available and affordable.

Abstract
The hypersensitivity syndromes are a group of diseases in which the cutaneous vasculature is altered through immunologic or nonimmunologic mechanisms. These reactions range in severity from mild to life-threatening and can be triggered by drugs, infectious agents, foods, or environmental allergens. Although their causes may vary, the morphologic appearance of these entities may be similar making a clinical diagnosis a challenge.
