Incidencia de síndrome de Stevens-Johnson y necrólisis epidérmica tóxica en Chile años 2001-2015 y su asociación con latitud / Hospital discharges due to Stevens-Johnson syndrome and toxic epidermal necrolysis in Chile from 2001 to 2015

Background: Stevens-Johnson Syndrome (SSJ) and Toxic Epidermal Necrolysis (NET) are infrequent and life-threatening mucocutaneous diseases, which occur predominantly as adverse drug reactions. Aim: To describe the frequency of SSJ and NET diagnoses at a national level, estimate their incidence and describe their distribution among the different regions of the country. Material and Methods: Analysis of hospital discharge databases available at the website of the Chilean Ministry of Health searching for the tenth version of the International Classification of Diseases (ICD 10) codes for SSJ or NET, between 2001 and 2015. Results: We analyzed 24,521,796 hospital discharges nationwide. SSJ caused 855 discharges, with a lethality of 2%. NET caused 128 discharges with a lethality of 16%. The global cumulative incidence was 3.87 cases per million inhabitants per year nationwide, with a trend line to increase incidence towards the regions of higher latitude. Conclusions: SSJ and NET are dermatological emergencies with high mortality. The increase in incidence towards regions at higher latitudes may suggest an association between these conditions and lower levels of vitamin D, correlated with latitude and exposure to UV radiation.

Epidermal necrolysis: SCORTEN performance in AIDS and non-AIDS patients

Abstract: Background: Stevens-Johnson syndrome and toxic epidermal necrolysis are life-threatening blistering drug reactions with high incidence of ocular sequela. The term 'Epidermal Necrolysis' has been recently used to better describe the full spectrum of the disease that includes Stevens-Johnson syndrome and toxic epidermal necrolysis at opposite ends, which differ by the extent of body surface area with epidermal detachment. SCORTEN is a mortality prognosis score for 'Epidermal Necrolysis' cases that still needed validation in acquired immunodeficiency syndrome. Objective: To evaluate the SCORTEN performance in acquired immunodeficiency syndrome, and the differences in outcomes between acquired immunodeficiency syndrome and non- acquired immunodeficiency syndrome cohorts. Methods: Retrospective cohort study of AIDS and non-AIDS 'Epidermal Necrolysis' cases admitted to a Brazilian reference center from 1990-2014. Results: Five deaths (16.7%) occurred as a consequence of EN in 30 AIDS patients, and seven (17.9%) in 39 non-AIDS patients, relative risk (RR) .92 (p=1.0). SCORTEN showed great performance, with an Area Under the Receiver Operating Curve (AUC) (ROC) of 0.90 with a 95% confidence interval ranging from .81 to .99. The performance of SCORTEN was better among non- AIDS patients than AIDS patients: AUC non- acquired immunodeficiency syndrome =0.99 (CI 05% 0.96-1.00), AUC acquired immunodeficiency syndrome = 0.74 (CI 95% 0.53-0.95), p=.02. Study Limitations: Heterogeneity of cases, wide variation of systemic corticosteroid doses when used. Conclusion: SCORTEN is valid for the Brazilian population, including among those patients with acquired immunodeficiency syndrome, and, as such, its use is recommended for aiding treatment choice in this subgroup of patients.

Stevens-Johnson syndrome and toxic epidermal necrolysis: epidemiological and clinical outcomes analysis in public hospitals

Abstract: Background: Adverse drug reactions are harmful and involuntary responses to drugs that occur at doses normally used for a given condition. Among them are Stevens-Johnson syndrome and toxic epidermal necrolysis, both rare and potentially fatal conditions. Objectives: To analyze the epidemiological and clinical characteristics related to patients diagnosed with Stevens-Johnson syndrome and toxic epidermal necrolysis in public hospitals in the Federal District - Brazil. Methods: Retrospective, cross-sectional and descriptive study, in which data were collected referring to patients hospitalized in the public healthcare system of the Federal District from 1999 to 2014. Results: Between 1999 and 2014, 86 cases of hospitalized patients with diagnosis of Stevens-Johnson syndrome and toxic epidermal necrolysis in the Federal District were reported. The majority of patients were women; the most affected age group was 0 to 10 years. Patients older than 60 years (elderly) represent 6.98% of the cases. Most patients admitted to the referral hospital were discharged. However, occurrence of deaths exceeded that of discharge in elderly patients. Limitations of the study: There is fragility in the registry of hospitalization of patients, both in the hospital information system and in the medical records of the reference hospital. Conclusion: There is a need for greater production and better dissemination of information on the incidence of adverse drug reactions.

Stevens-Johnson syndrome and toxic epidermal necrolysis at the University Hospital of the West Indies, Jamaica / El síndrome de Stevens-Johnson y la necrólisis epidérmica tóxica en el Hospital Universitario de West Indies, Jamaica

OBJECTIVE: Stevens-Johnson syndrome and toxic epidermal necrolysis are uncommon acute dermatologic disorders. The purpose of this study was to examine the frequency, aetiology and outcome of cases of Stevens-Johnson syndrome and toxic epidermal necrolysis admitted to the dermatology ward at the University Hospital of the West Indies. METHODS: This was a retrospective study looking at all patients who were admitted with a diagnosis of Stevens-Johnson syndrome, Stevens-Johnson syndrome/toxic epidermal necrolysis overlap syndrome and toxic epidermal necrolysis over a nine-year period. RESULTS: The results showed almost equal numbers of males and females. The drugs most commonly implicated were phenytoin and cotrimoxazole. The most common complications were hepatic impairment and ophthalmic complications. CONCLUSION: Stevens-Johnson syndrome and toxic epidermal necrolysis contribute significantly to morbidity and mortality of patients on the dermatology ward although mortality was low compared to other studies.

OBJETIVO: El síndrome de Stevens-Johnson (SSJ) y la necrólisis epidérmica tóxica (NET) son trastornos dermatológicos agudos poco frecuentes. El propósito de este estudio fue examinar la frecuencia, la etiología y el resultado de casos de síndrome Stevens-Johnson y necrólisis epidérmica tóxica ingresados en la sala de dermatología del Hospital Universitario de West Indies. MÉTODOS: Se trata de un estudio retrospectivo con todos los pacientes que fueron ingresados con diagnóstico de síndrome de Stevens-Johnson, síndrome de solapamiento entre el síndrome de Stevens-Johnson y NET, y necrólisis epidérmica tóxica, por un período de nueve años. RESULTADOS: Los resultados mostraron casi igual número de varones y hembras. Los fármacos más comúnmente implicados fueron la fenitoína y el cotrimoxazol. Las complicaciones más frecuentes fueron deterioro hepático y complicaciones oftálmicas. CONCLUSIÓN: El síndrome Stevens-Johnson y la necrólisis epidérmica tóxica contribuyen significativamente a la morbilidad y mortalidad de los pacientes en la Sala de Dermatología, aunque la mortalidad fue baja en comparación con otros estudios.

Cutaneous drug reactions in patients admitted to the dermatology unit at the University Hospital of the West Indies, Kingston, Jamaica / Reacciones cutáneas medicamentosas en pacientes ingresados en la Unidad de Dermatología del Hospital Universitario de West Indies, Kingston, Jamaica

OBJECTIVE: Cutaneous reactions are among the most common adverse reactions to drugs. The purpose of this study is to examine the aetiology and outcome of cutaneous drug reactions among patients admitted to the Dermatology Ward at the University Hospital of the West Indies. SUBJECTS AND METHODS: This was a retrospective study looking at all patients who were admitted with a diagnosis of a cutaneous drug eruption from January 1, 1997 to December 31, 2005. Data included patient demographics, date of admission to hospital, duration of hospitalization and a detailed drug history including any previous episodes of drug sensitivity. All drugs reportedly ingested by the patients up to three months prior to their cutaneous reaction were documented and the period of time between drug ingestion and the appearance of skin lesions was also noted. Clinical diagnosis, co-morbidities, histopathological diagnosis, final outcome and all ensuing disabilities were noted. The data retrieved were collated and analyzed using SPSS 12.0. RESULTS: The results showed a female to male ratio of 2.2:1. The categories of drugs most commonly implicated were antimicrobials followed by anti-epileptic drugs and nonsteroidal anti-inflammatory drugs. The most common form of drug eruption requiring admission was the exanthematous drug eruption followed by erythema multiforme, toxic epidermal necrolysis and Stevens-Johnson syndrome. CONCLUSION: In general, the causative agents identified and the types of drug eruptions were similar to those found in previous studies. However, the anti-epileptic drugs, phenytoin and carbamazepine, ranked among the most commonly implicated drugs which differ significantly from other studies.

Las reacciones cutáneas se hallan entre las reacciones adversas más comunes frente a los medicamentos. El propósito de este estudio fue examinar la etiología y la evolución clínica de las reacciones cutáneas medicamentosas entre pacientes ingresados a la sala de dermatología en el Hospital Universitario de West Indies. MÉTODOS: Este es un estudio retrospectivo que pasa revista a todos los pacientes que fueron ingresados con diagnóstico de erupción cutánea desde el 1ero. de enero de 1997 al 31 de diciembre de 2005. RESULTADOS: Los resultados mostraron una proporción hembra-varón de 2.2:1. Las categorías de los medicamentos más frecuentemente implicados fueron los antimicrobianos, seguidos por los medicamentos antiepilépticos y los antiinflamatorios no esteroideos. La forma más común de erupción que requirió ingreso a causa de medicamentos, fue la erupción exantemática medicamentosa seguida por el eritema multiforme, la necrólisis epidérmica tóxica, y el síndrome de Stevens-Johnson. CONCLUSIÓN: En general, los agentes causativos identificados y los tipos de erupciones medicamentosas, fueron similares a los hallados en estudios previos. Sin embargo, los antiepilépticos conocidos como fenitoína y carbamazepina, estuvieron entre los medicamentos más comúnmente implicados, presentándose en tal sentido una diferencia significativa con los otros estudios.

[Lyell's syndrome: a report of 16 cases]

Lyell's syndrome [SL] or toxic epidermal necrolysis is a rare mucocutaneous eruption, which is characterised by an acute necrosis of the totality of the epidermis +1-the mucosal epithelium. This is a serious affection considering the severity of systemic manifestations, the unprcdictable evolution, and the absence of specific therapy. To assess epidemiological and clinical features of this condition in our departments. This was a retrospective study concerning the cases of Lyell's syndrome carried in the dermatology and the intensive care department of Parhat Hached hospital over a 26 year period. Results: We listed 12 women and 4 with a mean age of 48,9 years. Epidermal detachmcnt varied between 26 and 80%of the body surface and mucus were involved in 87, 5%of cases. Systemic manifestatinns wcre noted in 11 patients. A drug etiology was found in 875%of cases, half of which was due to antibiotics. Our results are similar to those in the literature. Our study illustrates the severity of this toxiderma with a high mortality rate [43, 75%of cases], conformable with what was predicted by the severity-of-illness score "SCORTEN". Infectious complications wore the principal cause of death

Síndrome de Stevens-Johnson y necrólisis epidérmica tóxica: experiencia clínica en el Hospital Nacional Guillermo Almenara Irigoyen, Lima - Perú / Stevens-Johnson Syndrome and toxic epidermal necrolysis: clinical experience at the Hospital Nacional Guillermo Almenara Irigoyen, Lima-Peru

Objetivo: Describir las características clínicas de un grupo de pacientes diagnosticados de síndrome de Stevens-Johnsons (SSJ) y necrólisis epidérmica tóxica (NET). Material y métodos: Estudio retrospectivo, transversal y descriptivo realizado en el Hospital Nacional Guillermo Almenara Irigoyen entre junio de 2004 y mayo del 2007. Se revisó las historias clínicas de los casos hospitalizados, recogiendo la información sobre drogas responsables, tratamiento y resultado final. Resultados: Se estudiaron siete pacientes, cinco con diagnóstico de NET, uno con SSJ y uno con síndrome SSJ-NET. Cinco pacientes fueron mujeres y dos varones, con una edad media de 47 años.Los fármacos asociados fueron los anticonvulsivantes (fenitoína y lamotrigina) en tres pacientes, metamizol en dos, cotrimoxazol en uno y fluconazol también en uno. La mucosa oral fue afectada en todos los casos, la mucosa genital en cuatro y la mucosa conjuntival en tres. El tratamiento de elección fueron los corticoides en seis pacientes y se inicio de forma rápida en cuatro, evolucionando con mínimas complicaciones y solo uno de ellos presento secuelas oculares. Solo hubo un deceso en este grupo. Conclusiones: El SSJ y la NET en nuestros casos fueron causados principalmente por anticonvulsivantes y metamizol, fueron tratados en su mayoría con corticoides sistémicos. Drogas de uso creciente como fluconazol y lamotrigina también deben considerarse entre los medicamentos de riesgo.
