Múltiples reacciones adversas graves a fármacos en un paciente luego de la infección por COVID-19: informe de un caso / Drug-induced severe cutaneous adverse reactions in a patient after COVID-19 infection: case report

Durante la pandemia por COVID-19 se observaron diversas reacciones adversas a fármacos. Esto pudo haber estado relacionado con una mayor susceptibilidad inmunológica de los pacientes con SARS-CoV-2 a presentar este tipo de cuadros, así como también con la exposición a múltiples medicamentos utilizados en su tratamiento. Comunicamos el caso de un paciente con una infección respiratoria grave por COVID-19, que presentó 2 reacciones adversas graves a fármacos en un período corto de tiempo. (AU)

During the COVID-19 pandemic, various adverse drug reactions were observed. This could have been related to a greater immunological susceptibility of patients with SARS-CoV-2 to present this type of symptoms, as well as exposure to multiple drugs used in their treatment. We report the case of a patient with a severe respiratory infection due to COVID-19, who presented 2 serious adverse drug reactions associated with paracetamol in a short period of time. (AU)

Fotobiomodulação na Síndrome de Stevens-Johnson no Câncer de Mama Metastático: Relato de Caso / Photobiomodulation in Stevens-Johnson Syndrome in a Metastatic Breast Cancer: Case Report / La Fotobiomodulación en el Síndrome de Stevens-Johnson en el Cáncer de Mama Metastásico: Informe de Caso

Introdução: A síndrome de Stevens-Johnson é uma condição rara e potencialmente fatal que requer diagnóstico precoce e tratamento adequado para garantir bom prognóstico. Em virtude da complexidade da síndrome e da falta de tratamento padrão para as feridas, o uso da fotobiomodulação tem sido discutido. Relato do caso: Mulher, 30 anos, com câncer de mama metastático, portadora das síndromes de Stevens-Johnson e de Li-Fraumeni Like, em uso da fotobiomodulação como estratégia adjuvante no tratamento da dor e das feridas na pele. As feridas cutâneas eritematosas envolveram quase toda a superfície corpórea, com lesões escamosas, crostosas e bolhosas, dolorosas, com pontos hemorrágicos em região posterior de ambos os lóbulos das orelhas e na região occipital, dificultando a acomodação da paciente em decúbito lateral e em posição semirreclinada. Foram realizadas duas aplicações da fotobiomodulação (vermelho, com comprimento de onda de 660 nm) nas regiões occipital e de orelhas, com dose de 2 Joules por ponto; e 4 Joules em região escapular para analgesia (infravermelho, com comprimento de onda de 808 nm). Ambas as aplicações foram seguidas de mobilização e liberação miofascial na região escapular. Em 48 horas, houve regressão das lesões cutâneas e melhora da dor, facilitando posicionamento adequado e indolor no leito. Após 15 sessões de fisioterapia, a paciente recebeu alta hospitalar. Conclusão: O uso da fotobiomodulação se mostrou eficaz para o tratamento complementar da fase aguda da síndrome de Stevens-Johnson no que diz respeito à regeneração tecidual e analgesia.

Introduction: Stevens-Johnson syndrome is a rare but potentially fatal condition, which requires early diagnosis and treatment to ensure good prognosis. Due to the complexity of the syndrome and the lack of a standard wound care treatment, the use of photobiomodulation has been discussed. Case report: A 30-year-old woman with metastatic breast cancer and Stevens-Johnson and Li-Fraumeni Like syndromes using photobiomodulation as an adjuvant strategy in the treatment of pain and skin wounds. The erythematous cutaneous lesions involved almost the entire body surface with painful, scaly, crusted and bullous lesions with bleeding spots in the posterior region of both ears lobes and in the occipital region which made it difficult to accommodate the patient in lateral decubitus and in semi-recumbent position. Two photobiomodulation applications (red, with a wavelength of 660 nm) were performed, where lesions in the occipital region and ears were treated with a dose of 2 Joules per point and 4 Joules in the scapular region for pain relief (infrared, with a wavelength of 808 nm), followed by mobilization and myofascial release in the scapular region. In 48 hours, the cutaneous lesions reduced, and the pain improved, which facilitated the adequate and painless positioning in bed. After 15 physiotherapy sessions, the patient was discharged. Conclusion: Photobiomodulation has been shown to be effective in the complementary treatment of the acute phase of Stevens-Johnson Syndrome regarding tissue regeneration and analgesia.

Introducción: El síndrome de Stevens-Johnson es una condición rara y potencialmente fatal que requiere diagnóstico temprano y tratamiento adecuado para asegurar un buen pronóstico. Debido a la complejidad del síndrome y la falta de un tratamiento estándar de las heridas, se ha discutido el uso de fotobiomodulación. Informe del caso: Mujer, 30 años, con cáncer de mama metastásico, portadora de los síndromes de Stevens-Johnson y Li-Fraumeni Like en uso de la fotobiomodulación como estrategia adyuvante para el tratamiento del dolor y las heridas cutáneas. Las heridas cutáneas eritematosas comprometían casi toda la superficie corporal, con lesiones dolorosas, descamativas, costrosas y ampollosas, con puntos hemorrágicos en la región posterior de ambos lóbulos de las orejas y en la región occipital, que dificultaban la acomodación del paciente en decúbito lateral y en posición cómoda semirrecostada. Se realizaron dos aplicaciones de fotobiomodulación (rojo, con longitud de onda de 660 nm) en región occipital y auricular con dosis de 2 Joules por punto; y 4 Joules en la región escapular para analgesia (infrarrojo, con longitud de onda de 808 nm). Ambas aplicaciones fueron seguidas de movilización y liberación miofascial en la región escapular. En 48 horas hubo una regresión de las lesiones cutáneas y mejoría del dolor, lo que facilitó una adecuada e indolora posición en la cama. Después de 15 sesiones de fisioterapia, la paciente fue dada de alta del hospital. Conclusión: El uso de la fotobiomodulación demostró ser efectivo para el tratamiento complementario de la fase aguda del síndrome de Stevens-Johnson en lo que respecta a la regeneración tisular y la analgesia.

Reacciones cutáneas adversas graves en la infancia / Severe adverse skin reactions in the childhood

RESUMEN Las reacciones cutáneas a drogas son cada vez más frecuentes en edades pediátricas, con un alto impacto en la salud de los niños. Pueden manifestarse en formas muy disímiles, desde un exantema transitorio hasta cuadros graves con afectación multisistémica potencialmente fatales. En la presente revisión se hace énfasis en las farmacodermias graves en la infancia, con el objetivo de promover el conocimiento por parte del personal médico para facilitar su diagnóstico y tratamiento oportuno. Se desarrolló una búsqueda en la Biblioteca Virtual de Salud de Infomed y en Google: se revisaron 28 trabajos científicos sin limitación de año y país, 24 de ellos pertenecen a los últimos cinco años y de estos 17 a los últimos tres. El dominio de los elementos para el diagnóstico precoz y las opciones terapéuticas son indispensables para elegir la conducta adecuada frente a estas reacciones cutáneas graves y disminuir la morbimortalidad por estas afecciones (AU).

ABSTRACT Skin reactions to drugs are increasingly common at pediatric ages, with a high impact on children's health. They can appear in very dissimilar forms, from a transient rash to serious pictures with potentially fatal multisystem involvement. This review focuses on severe pharmacodermies in the childhood, with the aim of promoting medical staff knowledge to facilitate their timely diagnosis and treatment. A search was led in the Infomed Virtual Health Library and in Google: 28 scientific papers were reviewed without limitation of year and country, 24 of them belong to the last five years and from these 17 to the last three. Mastery of the elements for early diagnosis and therapeutic options are indispensable to choose the appropriate behavior against these serious skin reactions and to decrease morbidity and mortality due to these conditions (AU).

Necrólisis epidérmica tóxica en una adolescente diagnosticada de trastorno bipolar II y tratada con lamotrigina / Toxic epidermal necrolysis in an adolescent with Bipolar Disorder II and treated with Lamotrigine

Resumen La necrólisis epidérmica tóxica es una enfermedad cutánea severa, la mayoría de las veces desencadenada como reacción adversa a medicamentos, con alta morbilidad y mortalidad. La lamotrigina, junto a otros medicamentos estabilizadores del ánimo, constituye la causa medicamentosa más frecuente de esta complicación, consistente en necrosis y esfacelo de la epidermis y mucosas en más del 30 % de la superficie corporal, con la consecuente pérdida de líquidos y electrolitos, respuesta inflamatoria sistémica, susceptibilidad a infecciones y hasta sepsis, además de posibles secuelas ominosas. En la actualidad, el diagnóstico de trastorno bipolar se hace con mayor frecuencia, incluyendo al grupo etario de niños y adolescentes, pero tal proceso diagnóstico se caracteriza por dificultades y controversias en mayor cuantía que otros diagnósticos psiquiátricos. Ello obliga a una meticulosa elucubración diagnóstica y selección farmacológica, con pleno conocimiento de las moléculas del arsenal medicamentoso para, en caso de prescripción de lamotrigina, establecer una escrupulosa psicoeducación al paciente y sus familiares además de un seguimiento estricto y cercano. A propósito del caso de una adolescente diagnosticada de trastorno bipolar II, que recibió lamotrigina durante un episodio depresivo pero con un esquema posológico inadecuado, y desarrolló necrólisis epidérmica tóxica, revisamos y comentamos la literatura correspondiente. Concluimos en que es preciso extremar las precauciones al decidir el uso de lamotrigina para minimizar el riesgo de este severo efecto adverso.

Toxic epidermal necrolysis is a severe skin disease, most often triggered as an adverse drug reaction, with high morbidity and mortality. Lamotrigine, together with other mood stabilizer drugs, constitutes the most frequent drug that causes this complication, which consists of necrosis and detachment of the epidermis and mucosa in more than 30% of the body surface, with the consequent loss of water and electrolytes, systemic inflammatory response, susceptibility to infections and even sepsis, in addition to other possible ominous sequelae. Currently, the diagnosis of bipolar disorder is made more frequently, including the age group of children and adolescents, but such a diagnostic process is characterized by difficulties and controversies to a greater extent than other psychiatric diagnoses. This requires meticulous diagnostic process and pharmacological selection, with full knowledge of the molecules in the drug arsenal so, in case of lamotrigine prescription, it should be established scrupulous psychoeducation to the patient and their family members, as well as strict and close follow-up. A propos of the case of an adolescent girl diagnosed with bipolar II disorder, who received lamotrigine during a depressive episode but with an inappropriate posology, and developed toxic epidermal necrolysis, we reviewed and commented on the corresponding literature. We conclude that extreme caution is necessary when deciding the use of lamotrigine to minimize the risk of this severe adverse effect.

Cohort study of patients with Stevens-Johnson syndrome and toxic epidermal necrolysis in China: evaluation of risk models and new predictor of pulmonary consolidation on computed tomography / 医学前沿

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but severe diseases. This study aimed to validate the predictive ability of risk models in patients with SJS/TEN and propose possible refinement in China. Patients in the Department of Dermatology of Huashan Hospital from January 2008 to January 2019 were included. Results showed that the severity-of-illness score for TEN (SCORTEN) had a good discrimination (area under the receiver operating characteristic curve (AUC), 0.78), and it was superior to auxiliary score (AS) and ABCD-10, which indicates age, bicarbonate level, cancer, dialysis, and 10% involved body surface area (AUC, 0.69 and 0.68, respectively). The calibration of SCORTEN (Hosmer-Lemeshow goodness-of-fit test, P = 0.69) was also better than that of AS (P = 0.25) and ABCD-10 (P = 0.55). SCORTEN and ABCD-10 were similar (Brier score (BS), 0.04 and 0.04) in terms of accuracy of predictions. In addition, the imaging appearance of pulmonary consolidation on computed tomography was associated with high mortality. Refined models were formed using the variables and this imaging appearance. The refined AS and ABCD-10 models were similar in discrimination compared with the original SCORTEN (0.74 vs. 0.78, P = 0.23; 0.74 vs. 0.78, P = 0.30, respectively). Therefore, SCORTEN showed good discrimination performance, calibration, and accuracy, and refined AS or ABCD-10 model may be an option when SCORTEN variables are not available.

Stevens-Johnson syndrome/toxic epidermal necrolysis successfully treated with Chinese herbal medicine Pi-Yan-Ning: A case report / 中西医结合学报

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.

Fotobiomodulação na síndrome de stevens-johnson: relato de caso / Photobiomodulation for stevens-johnson syndrome: case report

Introdução: A Síndrome Stevens-Johnson (SSJ) é uma doença causada por hipersensibilidade a imunocomplexos e pode ser desencadeada por distintos fármacos, dentre eles a fenitoína. Devido sua complexidade e raridade, ainda nãohá consenso de tratamento padrão ouro, porém sabese da necessidade da atuação multidisciplinar. Para os cuidados com as feridas, pode-se citar os curativo se a fotobiomodulação (FBM). Objetivo: Relatar o uso da FBM como terapia complementar em um caso de SSJ no Hospital Universitário Regional dos Campos Gerais (HU-UEPG). Métodos: Paciente sexo feminino, 26 anos, deu entrada na unidade de terapia intensiva (UTI) com diagnóstico de SSJ secundária ao uso de fenitonína, escore de SCORTEN 1, com área sem epitélio íntegro 10- 30% e área acometida por lesões de 94,5%, poupando apenas o couro cabeludo. Foi abordada e tratada por uma equipe multidisciplinar e solicitado vaga em centro de especializado em queimados. No sétimo dia de UTI foi iniciado tratamento com FBM, 2 J por ponto, distância entre pontos de 2cm, comprimento onda vermelho (660nm), nas feridas que não apresentavam secreção, foram cinco sessões com intervalo de três dias entre a terceira e a quarta. Resultados: A paciente apresentou melhora visível das lesões cutâneas e recebeu alta hospitalar 5 dias após cessação da FBM. Conclusão: O uso da FBM pode ser efetiva no tratamento complementar da fase aguda SSJ desencadeada por fenitoína.

Introduction: Stevens-Johnson Syndrome (SJS) is a disease caused by hypersensitivity to immune complexes and can be triggered by different drugs, including phenytoin. Due to its complexity and rarity, there is still no consensus on gold standard treatment, but the need for multidisciplinary action is known. For wound care, dressings and photobiomodulation (PBM) can be mentioned. Objective: This study is to report the use of PBM as complementary therapy in a case of SJS at Hospital Universitário Regional dos Campos Gerais (HU-UEPG). Methods: A 26-year-old female patient was admitted to the intensive care unit (ICU) diagnosed with SJS secondary to the use of phenytoin, SCORTEN score 1, with an area without intact epithelium 10-30% and an area affected by injuries of 94.5 %, saving only the scalp. She was approached and treated by a multidisciplinary team which requested a place in a specialized burn center. On the seventh day of ICU, treatment with PBM, 2J per point was started, distance between points of 2cm, red wave length (660nm), in wounds that did not present secretion, with a total of five sessions with an interval of three days between the third and fourth. Results: The patient showed a visible improvement of skin lesions and was discharged from hospital 5 days after cessation of PBM. Conclusion: Use of PBM can be effective in complementary treatment of acute SJS phase triggered by phenytoin.

Necrolisis tóxica epidérmica en cuidados intensivos / Epidermal toxic necrolysis in intensive care

Se estudiaron dos pacientes ingresados en sala de cuidados intensivos polivalente, los cuales presentaron necrolisis tóxica epidémica (NTE), complicación poco frecuente que tiene una incidencia de 1 a 4 casos por millón de habitantes. La causa de la enfermedad en estos pacientes fue medicamentosa y los principales medicamentos implicados fueron anfotericin B y ciprofloxacino. Una de las cuestiones que hace interesante el reporte de estas reacciones adversas es que se trata del primer caso de NTE relacionada con el uso de Anfotericin B Liposomal que se reporta en Cuba y en el resto de la comunidad científica. El diagnóstico se confirmó por biopsia de piel, ambos pacientes presentaron un riesgo de muerte, según índice de Scorten, mayor al 50 por ciento. Por lo infrecuente que es el tratamiento de esta afección en una sala de cuidados intensivos polivalentes, por lo raro que es ver esta enfermedad en relación a estos antibióticos antes mencionados, por lo dramático del cuadro clínico y por la evolución tórpida de los pacientes, se realizó esta investigación con el objetivo de transmitir la experiencia y el conocimiento a la comunidad médica y científica en general y a los profesionales que laboran en las salas de terapia intensiva polivalente en particular(AU)

Two patients admitted to a multipurpose intensive care ward were studied. They showed epidemic toxic necrolysis (NTE), a rare complication that has an incidence of 1 to 4 cases per million inhabitants. Drugs were the cause of the disease in these patients and the main drugs involved were amphotericin B and ciprofloxacin. This is the first case of NTE related to the use of Liposomal Amphotericin B reported in Cuba and in the rest of the scientific community, which makes it interesting. The diagnosis was confirmed by skin biopsy, both patients had risk of death, according to the Scorten index, higher than 50 percent. This research was carried out with the aim of communicating the experience and knowledge to the medical and scientific community in general and to the professionals who work in multipurpose intensive care rooms in particular, since this condition is rare in a multipurpose intensive care room, it is rare in relation to the aforementioned antibiotics, its dramatic clinical status and the torpid evolution of patients(AU)

Erupção fixa bolhosa generalizada após reexposição à dipirona: relato de caso e revisão da literatura / Generalized bullous fixed drug eruption after reexposure to dipyrone: a case report and literature review

A erupção fixa à droga (EFD) é uma reação de hipersensibilidade tardia a medicamentos caracterizada por máculas ou pápulas eritematosas, violáceas ou acastanhadas, bem demarcadas, que aparecem após uso de uma medicação, e reaparecem na mesma localização após exposições repetidas. A erupção fixa à droga bolhosa generalizada (EFDBG) é uma variante rara da EFD que foi recentemente incluída pelo RegiSCAR no grupo das farmacodermias graves. Apresenta-se através de lesões cutâneas generalizadas características de EFD, com formação de bolhas, geralmente em pacientes com história prévia de EFD. Os principais medicamentos envolvidos na EFDBG são antibióticos e anti-inflamatórios não esteroidais. O diagnóstico é clínico, entretanto, a biópsia cutânea na fase aguda e o teste de contato após a recuperação do paciente, podem auxiliar a investigação. O tratamento requer geralmente apenas a suspensão do fármaco suspeito e medidas de suporte. Relatamos um caso de EFDBG em adolescente após reexposição à dipirona (metamizol) apesar da história prévia de hipersensibilidade a esta medicação. O objetivo deste relato é alertar sobre a importância do diagnóstico da EFDBG e ressaltar os principais pontos para o diagnóstico diferencial com a síndrome de Stevens-Johnson (SSJ)/necrólise epidérmica tóxica (NET).

Fixed drug eruption (FDE) is a delayed drug hypersensitivity reaction characterized by erythematous, violaceous or brownish well-demarcated macules or papules that appear after use of a medication and reappear at the same site after repeated exposures. Generalized bullous fixed drug eruption (GBFDE) is a rare FDE variant that has been recently included by RegiSCAR in the group of severe cutaneous adverse reactions to drugs. GBFDE presents as generalized cutaneous lesions characteristic of FDE, with blistering, usually in patients with a previous history of FDE. The main drugs involved in GBFDE are antibiotics and nonsteroidal anti-inflammatory drugs. The diagnosis is clinical, but some tests can help the investigation, such as skin biopsy in the acute phase and patch testing after patient recovery. Treatment usually requires suspension of the suspected drug and some supportive measures. We report a case of GBFDE after reexposure to dipyrone (metamizole) in an adolescent with a previous history of hypersensitivity to this drug. The aim of this report is to warn about the importance of diagnosing GBFDE and to highlight the main points for differential diagnosis with Stevens- Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN).

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.

Necrólisis epidérmica tóxica con buena respuesta a pulsos de metilprednisolona / Toxic epidermal necrolysis with good response to methylprednisolone pulses

Mujer de 15 años de edad, que después de recibir lamotrigina por epilepsia no controlada, desarrolló eritema generalizado, ampollas y descamación, con compromiso de mucosas y que abarcó del 60%-80% de la superficie corporal. El cuadro clínico de necrólisis epidérmica tóxica fue confirmado por biopsia de piel. Aparte de las medidas de soporte, se le administró pulsos de metilprednisolona con rápida respuesta favorable. (AU)

A 15-year-old woman, who, after receiving lamotrigine by uncontrolled epilepsy, developed generalized erythema, blisters and flaking, with mucous membrane involvement and covering 60%-80% of the body surface area. The clinical picture of toxic epidermal necrolysis was confirmed by skin biopsy. In addition to support measures, she was given methylprednisolone pulses with rapid favorable response. (AU)

Afecciones perianales no infecciosas, no neoplásicas, del adulto / Noninfectious, non-neoplasic adult perianal affections

Las enfermedades perianales del adulto, de carácter no infeccioso y no neoplásico, son un motivo de consulta poco frecuente. Se caracterizan por la variedad de su etiología y de su sintomatología clínica, y plantean dificultad en el diagnóstico y en la terapéutica.

The objective of this paper is to address a pathology that raises the need for interdisciplinary intervention anatomopathological, clinical and therapeutic considerations are included. (AU)

A case of toxic epidermal necrolysis induced by cytomegalovirus infection followed by DRESS (drug reaction with eosinophilia and systemic symptoms)

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome and toxic epidermal necrolysis (TEN) are severe cutaneous adverse reactions. Although viral reactivation is associated with DRESS syndrome, its role in TEN remains unclear. An 80-year-old woman visited our hospital because of fever and skin eruption. DRESS syndrome was diagnosed and was thought to caused by the use of the drug allopurinol. She was treated by discontinuation of the drug and administration of systemic steroids. She recovered from DRESS syndrome and was discharged from the hospital with tapering doses of steroids prescribed. One week after discharge, she visited our hospital again as the skin rash recurred and oral pain as well as oral and ocular mucosal lesions developed. In addition to the skin rash, blisters and Nikolsky's sign that were different from the skin lesions present in the previous DRESS syndrome were observed. Unlike those in DRESS syndrome, the viral serological test results were positive for anti-cytomegalovirus (CMV) IgM and CMV polymerase chain reaction. Therefore, it was thought that TEN was due to reactivation of CMV and she was treated this with ganciclovir and intravenous immunoglobulin. Here, we report a case of TEN caused by viral reactivation after DRESS syndrome developed after use of allopurinol which recovered after steroid treatment.

Conjuntivitis cicatrizal recalcitrante: Tratamiento de nueve pacientes con rituximab / Recalcitrant cicatrizing conjunctivitis. Treatment of nine patients with rituximab

La conjuntivitis cicatrizal es la consecuencia de distintas enfermedades oculares. Entre ellas, las más graves son el penfigoide cicatrizal y el síndrome de Stevens-Johnson crónico. El tratamiento de estas enfermedades con corticoides e inmunosupresores es habitualmente exitoso, pero unos pocos pacientes siguen un curso recalcitrante. En los últimos años se introdujo el uso de rituximab, asociado o no a gammaglobulina endovenosa, en forma abierta, para el control de la inflamación conjuntival. Describimos aquí el tratamiento de siete pacientes con penfigoide y dos con Stevens-Johnson recalcitrante, con rituximab. Ocho recibieron también gammaglobulina y todos alcanzaron la remisión de la actividad. Tres recayeron y recibieron dos o tres nuevos cursos de la medicación con mejoría sintomática. El rituximab probó ser una droga efectiva para el tratamiento de la conjuntivitis cicatrizal crónica recalcitrante.

Cicatrizing conjunctivitis is the final consequence of several diseases. The most severe among them are cicatricial pemphigoid and chronic Stevens-Johnson syndrome. Systemic immunosuppressive drugs and steroids are usually an effective approach to these diseases. However, a few patients follow a recalcitrant course unremitting to usual therapy. We describe the treatment with rituximab of seven patients with cicatricial pemphigoid and two with chronic Stevens-Johnson syndrome. Eight of them also received gammaglobulin and all achieved clinical remission. Three relapsed and required two or three new courses of rituximab with good control of disease activity. Rituximab proved to be an efficacious drug for chronic recalcitrant cicatrizing conjunctivitis.
