Introduction: Linear IgA bullous dermatosis (LABD) is a rare autoimmune disease. Although dapsone is the initial treatment, other immunomodulators are used in resistant cases or when dapsone is unavailable. Case report: A 12-year-old Mexican child, with no relevant medical history, developed in May 2023 a disseminated dermatosis affecting all body segments, including mucous membranes, characterized by erythematous patches and plaques evolving into the formation of serous and serosanguinous blisters and vesicles, distributed in a “string of pearls” pattern. LABD was suspected and confirmed by skin biopsy, which showed a subepidermal blister with neutrophilic infiltration and linear Immunoglobulin A deposits at the dermo-epidermal junction by direct immunofluorescence. Treatment with prednisone (2 mg/kg/day) and cyclosporine (5 mg/kg/day) resulted in improvement and lesion remission within 2 weeks. Both drugs needed to be discontinued for 3 months due to intermittent blistering. Cyclosporine was continued as maintenance therapy at a dose of 4 mg/kg/day for 8 months. Conclusions: The report highlights the use of cyclosporine as an alternative immunomodulator for DAAL, an immunosuppressive agent used in autoimmune disorders. Few cases, including this one, have described complete remission and control of the dermatosis with cyclosporine, accompanied by prednisone at the start of treatment. [ABSTRACT FROM AUTHOR]

Introducción: Las distrofias musculares son trastornos miogénicos hereditarios caracterizados por una atrofia muscular progresiva y una debilidad de distribución y gravedad variable. La población de Republica Dominicana es fruto de una mezcla de etnias, haciéndola portadora de una herencia cromosómica y ADN diverso, siendo susceptibles a poder presentar cualquier desorden de carácter hereditario. Material y métodos: Con una muestra de 17 pacientes obtenidos entre septiembre 2019- marzo 2020, se realizó un estudio retrospectivo, descriptivo y transversal, en el cual se hizo una revisión de los expedientes de la clínica de miopatías en la consulta de neurología pediátrica del Hospital Infantil Doctor Robert Reid Cabral, para describir el perfil clínico de los pacientes con distrofia muscular y los hallazgos de electromiografía en los casos que la misma. Resultados: se encontró que la distribución de la edad correspondió a 5-9 años en un 53%, siendo el sexo masculino, el más frecuente. En el 70.59% presentaron antecedentes familiares de distrofia muscular. Los principales motivos de consulta fueron cansancio y caídas frecuentes. Conclusión: En los hallazgos de electromiografía, el porcentaje de pacientes que presentó esta prueba con alteraciones fue de 88.24% y sin alteraciones el 11.76%. Esto nos demuestra, la gran utilidad de dicho estudio en el diagnóstico de las distrofias musculares en países donde no se cuenta con estudio molecular, siendo una de las pruebas esenciales en el abordaje diagnóstico de los pacientes con sospecha clínica de dichas patologías.

Introduction: The immediate-release solid oral products containing very soluble and permeable drugs are candidates for the biowaiver process. This work aims to compare in vitro, in silico, and in vivo data to establish if previously published prednisone oral tablet formulations are biowaiver candidates. Method: To achieve this goal, permeation studies were conducted on Caco-2 cells. A previous bioequivalence study between the test and the reference drug product was applied on an in silico evaluation using Gastroplus® to assess the bioequivalence of two other previously proposed formulations. Results: The apparent permeability coefficient for prednisone presented a value of 3.69 x 10-5 cm/s in 180 minutes. The bioequivalence study shows that the tested and reference product was equivalent. The in silico simulations successfully predicted the pharmacokinetics of the tested and the other two formulations since they were validated with the in vivo study. Both exhibit the same plasma concentration vs. time profiles. Conclusions: Through the in silico results, it is possible to infer that the other two formulations tested may be bioequivalent concerning the reference product. This result may be helpful in biowaiver requesting. Toward to reduce costs and the use of human beings in bioequivalence studies, this approach could be an essential way to work in the pharmaceutical industry. [ABSTRACT FROM AUTHOR]

Introducción: las recomendaciones actuales del tratamiento de la nefritis lúpica (NL) apuntan a dosis de glucocorticoides más bajas para lograr el control de la enfermedad y evitar el daño acumulado. Objetivo: conocer y comparar la respuesta al tratamiento de pacientes con NL proliferativa en su etapa de inducción con dos pautas de tratamiento con prednisona (PDN): dosis iniciales reducidas 30 mg/d. Método: se compararon variables clínicas, analíticas y terapéuticas de pacientes con NL proliferativa categorizados en dos grupos según la dosis inicial de prednisona (PDNi) estándar o reducida. Resultados: se estudiaron 21 pacientes con NL proliferativa (n=12 PDNi reducida vs. n=9 PDNi estándar). No hubo diferencias significativas en las variables clínicas y analíticas. Se observó una diferencia estadísticamente significativa en el número de pulsos de metilprednisolona (5 ± 2,95 PDNi 30 mg/d, p = 0,041) y en la dosis de prednisona acumulada a 6 meses (12,8 mg ± 4,9 PDNi 30 mg/d, p =0,008). No hubo diferencias significativas en la proporción de pacientes que alcanzaron la respuesta completa, en el tiempo hasta alcanzarla ni en los efectos adversos entre ambos grupos. Conclusiones: el esquema terapéutico del grupo PDNi

La insuficiencia suprarrenal primaria es un defecto en la producción de glucocorticoides, mineralocorticoides y andrógenos sexuales. Los pacientes afectados por esta condición se caracterizan por concentraciones bajas de cortisol y deficiencia de aldosterona con hiponatremia e hiperpotasemia concomitantes. La etiología más común es el desarrollo de anticuerpos contra la enzima 21 hidroxilasa. Otra causa importante de la insuficiencia suprarrenal primaria son las enfermedades infecciosas, en especial en los países de bajos ingresos. Entre las causas infecciosas que se han descrito se encuentran: Mycobacterium tuberculosis, el complejo de Mycobacterium avium, Neisseria meningitidis, Pseudomonas aeruginosa, Haemophilus influenzae, citomegalovirus, Pneumocystis jirovecii, Histoplasma capsulatum, Blastomyces dermatiditis, Cryptococcus neoformans, Cocciodiodes immitis, Nocardia spp. y Paracoccidioides brasiliensis. En este artículo se presenta la imagen de la tomografía de un paciente que presentó falla suprarrenal, con masas en las glándulas suprarrenales, cuya biopsia permitió establecer el diagnóstico final de paracoccidioidomicosis.

Tolosa Hunt Syndrome (STH) is a rare disease whose etiopathogenesis remains unclear. Most cases result from microvascular infarctions of the nerve at some point along its path, from the brain stem to the orbit. The most affected cranial nerves are the third, sixth, fourth and fifth, with involvement of multiple cranial pairs in most cases, presenting as a painful ophthalmoplegia and hemicranial headache. The etiology of an isolated oculomotor paralysis with normal pupil is often not clarified, even after neuroimaging and extensive laboratory research, and other etiologies, such as carotid aneurysm, carotid-cavernous fistula, thrombosis of the cavernous sinus, tumors and infection by herpes zoster. The treatment of choice is prednisone 1 mg / kg / day, orally, with clinical improvement in most episodes. In cases refractory to corticosteroid therapy, immunosuppressive drugs can be beneficial, with methotrexate and azathioprine being the most used. This article is a case report of a patient with a clinical diagnosis established for STH, which occurred in the city of Barbacena - MG. This work is justified by the rare occurrence of this syndrome, as well as by the timely discussion of the observed clinical picture and the response obtained with corticotherapy.

Background: The proteinuria selectivity index (PSI) can predict the response to prednisone in the primary nephrotic syndrome (PNS). Objective: To determine the association of prednisone response with the PSI in patients with PNS. Material and methods: With analytical cross-sectional design, pediatric patients with PNS were studied with at least six months of prior follow-up, at the Nuevo Hospital Civil de Guadalajara from 2014 to 2015. They were divided into poor response to prednisone (frequent relapses or resistance) and good response (habitual relapses). PSI was calculated with serum and urinary measurement of IgG and transferrin. Chi square and OR were used, with 95% CI. Results: 67 patients with relapsing PNS were studied. The response to prednisone had been good in 33 (49.3%) and poor in 34 (50.7%). The PSI was = 0.10 mg/mg in 23/67 (34.3%); 0.11-0.19 mg/mg in 15/67 (22.4%); and = 0.20 mg/mg 29/67 (43.3%). 3/34 patients (8.8%) presented = 0.1 mg/mg with poor response to prednisone and 20/33 presented good response (60.6%) (p < 0.001; OR: 0.6; 95% CI, 0.010-20). PSI between 0.11-0-19 mg/mg occurred in 8/34 patients (23%) with poor response to prednisone and in 7/33 with good response (21%). PSI = 0.20 mg/mg resulted in 23/34 patients 67.6%) with poor response to the steroid and in 6/33 with good response (18.2%) (p < 0.001; OR: 9.4; 95% CI, 3.01-29.42). Conclusions: In children with PNS, a PSI = 0.20 mg/mg was associated with a poor response to prednisone treatment and a PSI = 0.10 mg/mg with a satisfactory response. [ABSTRACT FROM AUTHOR]

RESUMEN La arteritis temporal o de células gigantes es una inflamación arterial que cursa con cefalea e hipersensibilidad del cuero cabelludo, entre otras formas de presentación. Se presentó el caso de un paciente masculino de 64 años de edad con antecedentes personales de hipertensión arterial que acudió a consulta pues desde hacía varios meses, venía presentando cefalea en región temporo-parietal a predominio derecho que se intensificaba al acostarse unido a lagrimeo del ojo homónimo, con hipersensibilidad a la palpación del cuero cabelludo y aumento de volumen de las arterias temporales superficiales, con velocidad de sedimentación normal lo cual se ha descrito en la literatura solo en un 5,4 % de los casos; se realizó biopsia de la arteria temporal superficial derecha que fue compatible con arteritis temporal, se realizó TAC craneal que descartó proceso expansivo intracraneal como causa de la cefalea. Se indicó tratamiento con prednisona con buena respuesta. ABSTRACT The temporal arteritis or gigantic cells is an arterial inflammation showing hypersensibility and headache in the scalp among others forms of presentation. It is presented a patient masculine of 64 years old who had personal antecedent of higher blood pressure, he went to the doctor because some months ago he suffered from a bad headache in the temporal-parietal region and when he went to sleep it was more intense, at the same time he presented tearing on his right eye with scalp hypersensibility and volume increase of the temporal arteries, with the normal erythrocyte sedimentation velocity which is describe only in literature in a 5,4 % of the cases, we performed a biopsy of the right superficial temporal artery, CT scan was performed that discarded an intracranial expansive process as the cause of the headache. It was treated with prednisone with good answer.

Glucocorticoids are steroid hormones that coordinate the systemic response to physical, chemical or biological stress. In the context of acne vulgaris these hormones contribute to the excessive production of sebum; however, they are used in daily clinical practice as therapeutic agents for their anti-inflammatory and anti-androgenic properties. In severe inflammatory acne, oral corticosteroids such as prednisone at low doses for 2-3 weeks can be co-administered with isotretinoin to potentially reduce inflammatory flares. Triamcinolone acetonide can be administered intralesionally at a dilution of 2.5 to 10 mg/mL in cystic lesions and 10 to 40 mg/mL in keloid scars, every 2-3 weeks. In acne fulminans prednisone plays a fundamental role and should be administered at doses of 0.5 to 1 mg/kg/day, with continuous treatment for 2 to 4 weeks prior to the gradual addition of isotretinoin. Oral corticosteroids at low doses can be considered monotherapy in patients with well-documented adrenal hyperandrogenism. Corticosteroids can be used in specific clinical scenarios of acne; clinical trials are needed to define optimal doses, duration of treatment, preferable agent and safety profile of these therapeutic agents.

ABSTRACT Chronic periaortitis (CP) is an umbrella term used to describe a group of nosologically allied conditions that include idiopathic retroperitoneal fibrosis (Ormond's disease), inflammatory abdominal aortic aneurysm, and perianeurysmal retroperitoneal fibrosis. Retroperitoneal fibrosis encompasses a range of diseases characterized by the presence of a fibro-inflammatory tissue, which usually surrounds the abdominal aorta and the iliac arteries and extends into the retroperitoneum to envelop neighboring structures-ureters. Retroperitoneal fibrosis is generally idiopathic, but can also be secondary to the use of certain drugs, malignant diseases, infections, and surgery. Here we describe a 5 years follow up (2006-2011) of 5 patients admitted to our hospital with symptoms, laboratory, imaging and pathologic finding compatible with retroperitoneal fibrosis. We review our clinical course of our patient with respect to the literature.

RESUMEN Y CONCLUSIONES 1. Se presentan 28 casos de tiroiditis sub-aguda, 4 en hombres y 24 en mujeres, atendidos en Consulta Privada durante un lapso de 11 años; de ellos 26 fueron tratados mediante drogas con acción glucocorticoide. 2. Se emplearon : a) prednisona per os, a dosis decreciente de 10 a 2.5 mg cada 8 horas durante 10 a 30 días, en 14 casos; b) dexametasona per os, a dosis decreciente de 0.4 a 0.1 mg cada 8 horas durante 13 días, en 1 caso; c) acetato del éster de 6-metil-prednisolona por vía intramuscular, a dosis única de 40 mg. 3. En 20 pacientes con tiempo de evolución de la enfermedad menor de 50 días, se obtuvo mejoría definitiva en todos ellos: 12 mediante prednisona y 8 mediante acetato de 6-metil-prednisolona. 4. En 6 pacientes con tiempo de evolución de la enfermedad mayor de 50 días, se obtuvo solamente mejoría transitoria, mediante prednisona, dexametasona o acetato de 6-metilprednisolona; 5 de ellos presentaron franca recidiva, controlable mediante glucocorticoide distinto al empleado como primer agente terapéutico. 5. El autor considera como el método de elección en el tratamiento actual de la tiroiditis subaguda en fase inicial o de daño progresivo tiroidiano auto-inmune, la administración intra-muscular de 40 mg de acetato del éster de 6-metilprednisolona, en una sola dosis.

El pioderma gangrenoso es una enfermedad de etiología desconocida, con variedad de manifestaciones clínicas especialmente cutáneas, de difícil diagnóstico, de evolución crónica, con exacerbaciones y remisiones frecuentes, en la cual no existe un tratamiento de elección efectivo, por lo que su respuesta a la terapia es muy variable. Se presentó el caso de una mujer, mestiza, de 64 años de edad, con antecedentes patológicos personales de gastritis, hipertensión arterial y cardiopatía isquémica, con un año de evolución de una lesión ulcerada en primer artejo de pie derecho, con fracasos terapéuticos anteriores al diagnóstico. Se le realizaron estudios hematológicos e histopatológico, confirmándose un pioderma gangrenoso, que respondió favorablemente a la terapia con prednisona, dapsona y oxigenación hiperbárica.

OBJECTIVE: To evaluate the effect size of oral corticosteroid treatment on eosinophilic bronchitis in asthma, through systematic review and meta-analysis. METHODS: We systematically reviewed articles in the Medline, Cochrane Controlled Trials Register, EMBASE, and LILACS databases. We selected studies meeting the following criteria: comparing at least two groups or time points (prednisone vs. control, prednisone vs. another drug, or pre- vs. post-treatment with prednisone); and evaluating parameters before and after prednisone use, including values for sputum eosinophils, sputum eosinophil cationic protein (ECP), and sputum IL-5-with or without values for post-bronchodilator FEV1-with corresponding 95% CIs or with sufficient data for calculation. The independent variables were the use, dose, and duration of prednisone treatment. The outcomes evaluated were sputum eosinophils, IL-5, and ECP, as well as post-bronchodilator FEV1. RESULTS: The pooled analysis of the pre- vs. post-treatment data revealed a significant mean reduction in sputum eosinophils (↓8.18%; 95% CI: 7.69-8.67; p < 0.001), sputum IL-5 (↓83.64 pg/mL; 95% CI: 52.45-114.83; p < 0.001), and sputum ECP (↓267.60 µg/L; 95% CI: 244.57-290.63; p < 0.0001), as well as a significant mean increase in post-bronchodilator FEV1 (↑8.09%; 95% CI: 5.35-10.83; p < 0.001). CONCLUSIONS: In patients with moderate-to-severe eosinophilic bronchitis, treatment with prednisone caused a significant reduction in sputum eosinophil counts, as well as in the sputum levels of IL-5 and ECP. This reduction in the inflammatory response was accompanied by a significant increase in post-bronchodilator FEV1.

O estudo tem o objetivo de identificar efeitos indesejáveis da ribavirina, prednisona e DMSO em cães naturalmente infectados com o vírus da cinomose. Foram utilizados 60 cães apresentando quadro neurológico da cinomose com evolução de 10 dias. Os animais foram internados e receberam tratamento de suporte; foram avaliados diariamente e realizados hemograma, dosagem bioquímica e exame de urina tipo I. Os grupos 1 e 2 foram tratados com ribavirina e sua associação com DMSO; os grupos 3 e 4 com DMSO e prednisona e o grupos 5 com ribavirina e prednisona e o grupo 6 com ribavirina, prednisona e DMSO. Os animais foram anestesiados para a colheita de líquor, medula óssea e sangue, antes do tratamento para diagnóstico através da RT-PCR. As amostras negativas foram analisadas pela técnica de hn-PCR. Todos os animais apresentaram resultado positivo em pelo menos uma das duas reações. O efeito adverso da ribavirina e a sua associação com a prednisona foi a anemia hemolítica, que foi confirmada pela observação de bilirrubina na urina apenas dos cães tratados com ribavirina.

Feline infectious peritonitis (FIP) is a serious polysystemic viral disease caused by feline infectious peritonitis virus (FIPV), a mutation of feline enteric coronavirus (FECV). Cats aged 3 months to 3 years are reported to be more frequently affected (70% of the animals with the disease presents the age of 1 year). However, the PIF can affect cats of all ages, including older animals. Males and cats of the Persian breeds, Bengals and Ragdols are more prone. It is an invariably fatal immune disease caused by feline infectious peritonitis virus (FIPV). The transmission occurs FECV by oro-faecal route through contact in such a cat with the feces of an infected cat, particularly by mutual us the litter. Although infrequent, can occur transmissão by licking and shared use of containers and drinking fountains. This study aims to report a case of wet FIP in feline patient, from its history to the outcome of your treatment. [ABSTRACT FROM AUTHOR]

BACKGROUND: The increasing in the number of kidney transplant recipients has favored, more frequently than before, the emergence of dermatoses and warranted their study through subsequent publications. OBJECTIVES: to evaluate the frequency of dermatoses in kidney transplant recipients. METHODS: kidney transplant recipients with suspected dermatoses between March 1st 2009 and June 30th 2010. RESULTS: 53 patients (28 males and 25 females), aged between 22 and 69 (mean age = 45 years) were evaluated. Most of them came from the cities of Ceilândia, Samambaia and São Sebastião/DF, and had already been transplanted for 5 to 10 years before (37.7%); 62.3% were recipients of living donors and 83% were prednisone-treated. The most prevalent dermatoses were of fungal (45.3%) and viral (39.6%) etiologies. Among the non-melanoma malignant neoplasms, the basal cell carcinoma prevailed (six cases), in spite of the low incidence. Concerning fungal dermatoses, 12 cases of onychomycosis, five of pityriasis versicolor and four of pityrosporum folliculitis were reported. For diagnosis, in most cases (64.2%), laboratory examinations (mycological and histopathological) were performed. CONCLUSION: cutaneous manifestations in kidney transplant recipients are generally secondary to immunosuppression. The infectious dermatoses, especially those of fungal origin, are frequently found in kidney transplant recipients and their occurrence increases progressively according to the time elapsed from the transplantation, which makes follow-up important. FUNDAMENTOS: o crescente aumento do número dos transplantados renais tem favorecido o aparecimento mais frequente das dermatoses e permitido o estudo em sucessivos trabalhos. OBJETIVOS: avaliar a frequência das dermatoses em pacientes transplantados renais. MÉTODOS: captação de pacientes transplantados renais durante o período de 1° de março de 2009 a 30 de junho de 2010 com suspeita de dermatoses. RESULTADOS : foram avaliados 53 pacientes (28 homens e 25 mulheres), entre 22 e 69 anos (com uma média de 45 anos), a maioria procedente de Ceilândia, Samambaia e São Sebastião/DF, entre 5 e 10 anos de transplante renal (37,7%), sendo 62,3% receptor de doador vivo e 83% em uso de prednisona. As dermatoses mais prevalentes foram as de etiologia fúngica (45,3%) e viral (39,6%). Das neoplasias malignas não-melanoma, apesar da baixa incidência, predominou o carcinoma basocelular (seis casos). Com relação s dermatoses de origem fúngica, ocorreram 12 casos de onicomicoses, cinco casos de pitiríase versicolor e quatro casos de foliculite pitirospórica. Para realização do diagnóstico, na maioria dos casos (64,2%), foi utilizado os exames laboratoriais ( micológicos e histopatológicos). CONCLUSÃO: as manifestações cutâneas em pacientes transplantados renais são geralmente secundárias imunossupressão. As dermatoses infecciosas, principalmente as de etiologia fúngica, são frequentes em pacientes transplantados renais, e sua ocorrência aumenta progressivamente, conforme o tempo transcorrido, a partir do transplante, sendo importante o acompanhamento.

Se realizó un estudio prospectivo, aplicado y analítico para determinar la efectividad del tratamiento con altas dosis de dexametasona en pacientes con trombocitopenia inmune primaria crónica atendidos en la consulta de hemostasia del Instituto de Hematología e Inmunología en el período comprendido entre abril de 2008 y abril de 2011. Se estudiaron 30 pacientes, 18 del sexo femenino y 12 del masculino, con una edad promedio de 37 años. Se alcanzó una respuesta favorable en 17 pacientes (68,0 %), de ellos, en 14 la remisión fue completa y en 3 parcial. No se obtuvo respuesta en 8 pacientes. Se observó un aumento significativo del recuento plaquetario entre el inicio y el final del tratamiento. Las remisiones se obtuvieron tempranamente, entre el primero y el tercer ciclo, y no se observaron respuestas tardías. La mayoría de los enfermos que respondieron a tratamientos previos con prednisona tuvieron una respuesta favorable a la dexametasona. Por lo general, los efectos adversos fueron leves y los más frecuentes fueron: mialgias, edemas y artralgias. En 3 pacientes fue necesario interrumpir el tratamiento por efectos indeseables y 9 mantuvieron la remisión durante el período de seguimiento. La dexametasona en altas dosis constituye una alternativa eficaz y segura en pacientes con trombocitopenia inmune primaria crónica.A prospective, analytical and applied study was conducted to determine the effectiveness of treatment with high-dose dexamethasone in patients with chronic primary immune thrombocytopenia, who were assisted at the Hemostasis service of the Institute of Hematology and Immunology from April 2008 to April 2011. 30 patients, 18 females and 12 males with an average age of 37 years were studied. Favorable response was achieved in 17 patients (68.0%), out of them, 14 had complete and 3 had partial remission respectively. No response was obtained in eight patients. A significant increase in platelet count was observed during the whole therapy. Referrals are obtained early, from the first to the third cycle, and late responses were not observed. Most patients who responded to previous treatment with prednisone had a favorable response to dexamethasone. In general, adverse events were mild and the most frequent were myalgia, edema, and arthralgias. Three patients required stopping the treatment because of side effects and nine maintained remission during the follow-up period. High-dose dexamethasone is an effective and safe alternative treatment in patients with chronic primary immune thrombocytopenia.

Os glicocorticóides são muito utilizados para fins antiinflamatórios e imunossupressores, porém apresentam importantes efeitos colaterais no fígado. O exame ultrassonográfico é um método não-invasivo que avalia a anatomia intra-hepática e possibilita a caracterização de alterações no parênquima decorrentes dos efeitos indesejáveis dos glicocorticóides. O histograma é uma mensuração ultrassonográfica que minimiza a subjetividade do exame, permitindo uma avaliação quantitativa da ecotextura e da ecogenicidade do órgão. Exames citopatológicos e histopatológicos podem auxiliar no diagnóstico de lesões hepáticas induzidas por corticóides. O objetivo deste trabalho foi avaliar os efeitos da terapia com prednisona no fígado de cães por meio de exames citopatológicos, histopatológicos e ultrassonográficos. Para isto, administrou-se em 11 cães adultos prednisona na dose de 2 mg/kg a cada 24 horas durante 14 dias, sendo feita análise ultrassonográfica pela técnica de histograma e coletadas amostras guiada por ultrassom para avaliação citopatológica e histopatológica no primeiro e último dia de administração do medicamento. A partir dessas mensurações pelo histograma, foi possível detectar um significativo aumento da ecogenicidade hepática ao final do protocolo experimental. As análises citopatológicas e histopatológicas demonstraram presença de vacuolização e granulação citoplasmática promovendo um aumento no tamanho dos hepatócitos. Verificou-se que mesmo em curtos períodos e em dosagens terapêuticas, a prednisona promove importantes efeitos colaterais sobre o parênquima hepático.

Acne fulminans é uma manifestação rara, que pode ocorrer durante a evolução da acne vulgar, principalmente, em adolescentes masculinos. Uso de isotretinoína, testosterona, e reações imunológicas exacerbadas no organismo são desencadeantes relacionados. Sinais, sintomas e alterações laboratoriais como: febre, hepatomegalia, poliartralgia, leucocitose, plaquetose, aumento de provas inflamatórias e transaminases, são característicos. A cintilografia óssea pode detectar lesões líticas em vários sítios do esqueleto. O tratamento é realizado com prednisolona, isotretinoína e antibióticos se infecções secundárias. Este caso relata um paciente masculino com diagnóstico de acne grau III, que desenvolveu acne fulminans e sacroileíte bilateral, com incapacidade de deambulação após início de terapia com isotretinoínaAcne fulminans is a rare manifestation that may occur during the evolution of acne vulgaris primarily in male adolescents. Use of isotretinoin, testosterone, and exacerbated immune responses in the body are related triggers. Signs, symptoms and laboratory findings such as fever, hepatomegaly, polyarthralgia, leukocytosis, plaquetose, increased inflammatory markers and transaminases, are characteristic. A bone scan can detect osteolytic lesions in multiple skeletal sites. The treatment is performed with prednisolone, isotretinoin and antibiotics if secondary infection is present. This case describes a male patient with a diagnosis of grade III acne, who developed acne fulminans and bilateral sacroiliitis with inability to ambulate, after initiation of therapy with isotretinoin

O líquen plano hipertrófico é uma variante do líquen plano, com pronunciada hiperplasia epidérmica em resposta à coçadura persistente. Clinicamente, caracterizam-se por placas hiperceratósicas, simétricas, de coloração cinza-violácea, com predileção pela região pré-tibial. O prurido intenso, a refratariedade aos tratamentos convencionais e a possibilidade de associação de um carcinoma epidermoide às lesões de longa duração impõem um tratamento eficaz. Os corticoides são considerados o tratamento de primeira linha e podem ser aplicados topicamente ou empregados de forma sistêmica. Outras modalidades terapêuticas propostas são a fototerapia com UVB-NB ou PUVA, imunossupressores e retinoides sistêmicos, com destaque para a acitretina. Relatamos um caso com apresentação clínica exuberante e excelente resposta à acitretin, totalizando um seguimento de nove mesesHyperthrofic lichen planus is considered a variant of lichen planus with marked epidermal hyperplasia in response to persistent itch. It is clinically, characterized by symmetric hyperkeratotic plaques, of purplish-grey color, often located in the pretibial region. Intense pruritus, refractoriness to conventional treatments and the possibility of association of the long-term injuries with squamous cell carcinoma requires an effective treatment. The first-line treatment is corticosteroids which can be applied either topically or systemically. Other therapeutic modalities proposed are: NB-UVB phototherapy or PUVA, immunosuppressive drugs and systemic retinoids, notably acitretin. We report a case with exuberant clinical presentation of hyperthrofic lichen planus with excellent response to acitretin after nine months of treatment

It is reported a case of an eight-year-old Yorkshire Terrier dog, with a history of prolonged use of prednisone in a dosage of 1mg/kg of body weight each 24 hours during two years. The helical computed tomography revealed hepatomegaly associated to a hyperattenuation of the parenchyma, with a radiodensity value of 82.55 Hounsfield units (HU). The spleen presented a mean radiodensity of 57.17HU, and a radiodensity difference of 25.38HU was observed between the two organs. Based on the history and findings of imaging technique, it was determined the presumptive diagnosis of steroidal hepatopathy compatible with accumulation of hepatic glycogen. It was concluded that computed tomography enabled the characterization of hepatic injury and the presumed diagnosis of steroidal hepatopathy

La mielofibrosis idiopática crónica (MIC), también conocida como metaplasia mieloide agnogénica, mielofibrosis primaria, mieloesclerosis con metaplasia mieloide, y mielofibrosis idiopática, se caracteriza por esplenomegalia, hematopoyesis extramedular, anemia progresiva, reacción leucoeritroblástica, hematíes en lágrimas en sangre periférica y fibrosis en médula ósea. Se han obtenido beneficios modestos con las terapias para la anemia (eritropoyetina y andrógenos) o la esplenomegalia (hidroxiurea, interferón-alfa). Ninguno de estos regímenes confiere un beneficio de supervivencia o cambio demostrable en la fibrosis intramedular. La ausencia de tratamiento eficaz para la enfermedad ha llevado al estudio de sus mecanismos patogénicos y el uso de nuevas alternativas terapéuticas. Se describen 2 pacientes con diagnóstico de MIC de 9 y 5 años de evolución que debido a los altos requerimientos transfusionales y la gran esplenomegalia, se les administró tratamiento con talidomida y prednisona. El tratamiento combinado logró aumento de las cifras de hemoglobina y de los conteos de plaquetas y una reducción y eliminación de los requerimientos transfusionales.Chronic idiopathic myelofibrosis (CIM) also known as agnogenic myeloid metaplasia, primary myelosclerosis with myeloid metaplasia and idiopathic myelofibrosis is characterized by splenomegalia, extramedullary hematopoiesis, progressive anemia, leukoerythroblastosis reaction, tears white cells in peripheral blood and bone marrow fibrosis. There have been modest benefits with anemia therapies (erythropoietin and androgens) or the splenomegalia (hydroyurea, alpha-interferon). Neither of these regimes confers survival benefit or a demonstrable change in extramedullary fibrosis. The lack of an effectiveness treatment for this disease has leads us to study its pathogenic mechanisms and the use of new therapeutical alternatives. Two cases are described diagnosed with CIM with a course of 9 and 5 years and due to the high transfusion requirements and a significant splenomegalia it was necessary to administer a treatment with thalidomide and prednisone. Combination treatment achieved an increase in hemoglobin figures and of platelet counts and a decrease and elimination of transfusion requirements.

A pitiríase liquenoide é dermatose incomum, idiopática, com espectro clínico-histopatológico onde inclui a forma varioliforme aguda (doença de Mucha-Habermann), sua variante febril úlceronecrótica e a forma crônica. Manifestações sistêmicas podem ocorrer na variante febril úlcero-necrótica, com relatos de casos fatais em adultos. Relata-se o caso de um paciente jovem, com diagnóstico clínico e histopatológico de doença de Mucha-Habermann, variante febril úlcero-necrótica, e acometimento mucoso exuberante, fato ocasional, mesmo nas formas mais graves de pitiríase liquenoide. Além do aspecto clínico inusitado, demonstra-se excelente resultado terapêutico, com a associação de prednisona e metotrexato.Pityriasis lichenoides is a rare idiopathic cutaneous disorder, with a clinical-histopathological spectrum comprising the acute varioliform form (Mucha-Habermann's disease), its febrile ulceronecrotic variant, and its chronic form. Systemic manifestations may occur in the febrile ulceronecrotic variant, with reports of adult mortality. The case of a young male patient with clinical and histopathological diagnosis of Mucha-Habermann’s disease, febrile ulceronecrotic variant, with severe mucosal involvement - an occasional incidence even in the most severe forms of pityriasis lichenoides - is presented. In addition to the atypical clinical aspect, an excellent therapeutic result is shown with the association of prednisone and methotrexate.

Foram utilizados 25 ratos (Rattus novergicus) submetidos a trauma experimental da medula espinhal, empregando-se aparelho estereotáxico com um peso de 50,5g comprimindo a duramáter durante cinco minutos. Após o trauma, os animais foram divididos em cinco grupos de cinco. O grupo A (controle) recebeu placebo oito horas após o trauma; os grupos B, C, D e E receberam prednisona oito, 24, 48 e 120 horas após o trauma, respectivamente. A prednisona foi administrada na dose inicial de 2mg/kg, durante cinco dias, com diminuição progressiva até o 26º dia. Os animais foram avaliados conforme a capacidade motora, posicionamento proprioceptivo, reflexo de localização, plano inclinado e sensibilidade dolorosa. Após 33 dias da cirurgia, foram sacrificados para avaliação histológica das medulas espinhais. Observaram-se degeneração das raízes nervosas, necrose medular, inflamação local e reação glial, sem diferenças entre os grupos. Não houve correlação entre os testes neurológicos. A utilização da prednisona na lesão medular aguda não teve efeito diferenciado com o tempo e não foi prejudicial na recuperação neurológica, mesmo quando utilizada tardiamente.Twent-five rats (Rattus novergicus) were submitted to an experimental spinal cord injury by using a 50.5g stereotaxic equipament to apply pressure on the duramater during five minutes. After the spinal cord injury, the animals were randomly distributed into five groups of five animals each: one group received placebo 8 hours after injury and the remaining four groups received prednisone at 8, 24, 48, and 120 hours after injury. Prednisone was applied at 2mg/kg dosage during five days and progressively reduced until the 26th day. Animals were evaluated by motor capacity, proprioceptive positioning, locating reflex, inclined plan, and sensibility to pain. The animals were sacrificed 33 days after surgery for histological study of the spinal cords that revealed degeneration of the rootlets, necrosis, inflammatory foci, and reactive gliosis, with no significant differences among the treated groups. The administration of high dosages of prednisone to animals with acute spinal cord injury had no deleterious effects on neurological recovery, even when used late.

Contact allergic reactions to topical corticosteroids are common. Cutaneous hypersensitivity reactions to systemically administered corticosteroids might occur though less frequently. The purpose of this literature review is to examine reported cases of cutaneous reactions to systemically administered corticosteroids. The data are presented considering route of administration, type of drug, type of reaction, and testing results. Corticosteroid classifications, cross-reactions, and allergy testing methods are also discussed.São comuns as reações alérgicas de contato a corticóides tópicos. Podem ocorrer reações cutâneas de hipersensibilidade a corticóides sistêmicos, mas são menos frequentes. O objetivo desta revisão da literatura é examinar relatos de casos de reações cutâneas a corticóides sistêmicos. Os dados apresentados levam em consideração a via de administração, tipo de medicamento, tipo de reação e resultados dos testes. A revisão discute também sobre classificações de corticóides, reações cruzadas e testes alérgicos.

Chromoblastomycosis is a subcutaneous and progressive mycosis caused by a black fungus of the Herpotrichiellaceae family. Squamous nodules, verrucous plaques, atrophic plaques and ulcerative lesions characterize it. The treatment is difficult and commonly there is resistance, moreover in extensive lesions and in immunosuppressed patients. This paper reports a 15 year-evolution chromoblastomycosis case in a non-controlled diabetic patient with self-medicated 50mg/ day prednisone along within 15 years. Samples from affected area were taken for direct examination by KOH and culture in Sabouraud dextrose agar, and modified Sabouraud. We also obtained serum glucose level and glycated hemoglobin. Fumagoid cells were observed in direct microscopy by KOH, and a black fungus colony in Sabouraud dextrosa agar and modified Sabouraud. Fonsecaea pedrosoi was identified, so we concluded chromoblastomycosis; 233 mg/dL glucose and 8.4% glycated hemoglobin were reported. We prescribed itraconazole (400mg daily) and cryosurgery with liquid nitrogen (monthly application) for 58 weeks. In addition, patient was evaluated by Internal Medicine department where control of diabetes and progressive weaning of steroids were made. Patient is disease free at the 9-month follow-up. In the context of a chromoblastomycosis patient with immunosuppression risk factors, as diabetes and the chronic intake of steroids, treatment should be combined, in general, healing is difficult, and so an integral evaluation is important.

Justificación y Objetivo: La nefritis lúpica es considerada como el prototipo de las glomeru-lonefritis mediadas por complejos inmunes. Existe gran variedad de manifestaciones clínicas y cambios histológicos asociados con esta patología. Los pacientes que la padecen tienen un elevado riesgo de deterioro progresivo de la función renal como resultado de la interacción de mecanismos inmunológicos y esclerosantes crónicos de lesión renal. El monitoreo de parámetros serológicos, la excreción renal de proteínas, y especialmente el sedimento urinario facilita el reconocimiento del pronóstico y el tratamiento de este desorden. Se realizó la presente investigación para comparar la respuesta de los pacientes diagnosticados con nefritis lúpica a los diferentes esquemas terapéuticos empleados en el tratamiento de esta patología, en el Servicio de Reumatología del Hospital México. Métodos: Se realizó un análisis retrospectivo tranversal de tipo descriptivo en el que se incluyeron los expedientes clínicos de pacientes diagnosticados con nefropatía lúpica en la Consulta Externa del Servicio de Reumatología del Hospital México en el período de tiempo comprendido entre 1990-1999. Se realizó una comparación de la respuesta a los diferentes regímenes terapéuticos empleados para el tratamiento en cada paciente. Resultados: La población de pacientes diagnosticados con nefropatía lúpica en los años mencionados fue de un total de 65. El sexo femenino predominó en una proporción de 5 a 1. El grupo de edad más frecuente fue el de los 20 a 40 años. El hallazgo histológico más frecuente en las biopsias renales fue la nefropatía lúpica clase IV. De los distintos esquemas terapéuticos, el más utilizado fue el de prednisona más ciclofosfamida, correspondiendo a un 52,31% del total, y fue con este esquema con el único que se obtuvo mejoría en la totalidad de los parámetros analizados luego del empleo del mismo. La ciclofosfamida fue el medicamento que presentó mayor número de efectos adversos. Conclusión: Se comprueba mediante este estudio la mayor eficacia en el tratamiento de las complicaciones de los pacientes con nefropatía lúpica cuando se utiliza el esquema medicamentoso de prednisona más ciclofosfamida

A prescrição de drogas anti-reumáticas em pacientes férteis deve ter em conta o conhecimento atual sobre os efeitos na concepção, gestação e lactação. Um aconselhamento que levasse em consideração os riscos e benefícios do planejamento da gravidez, quando possível, seria o ideal. Com a incorporação de novas substâncias e o aparecimento constante de novos dados na literatura, esse assunto deve ser continuamente atualizado. O estagiamento de acordo com o fator de risco estabelecido pelo FDA é algumas vezes contraditório em relação a nossa prática, em parte porque os estudos em modelos animais podem não ser diretamente aplicáveis a humanos. A terapia com agentes modificadores da resposta biológica é aparentemente segura durante a gestação, considerando-se que tais agentes sejam compostos por moléculas grandes, incapazes de atravessar a placenta. Antiinflamatórios não-esteroidais (incluindo os inibidores específicos de COX-2) podem prejudicar a implantação do óvulo, mas o seu uso é possível no caso da gestação estar em curso, devendo ser evitados após 32 semanas do início da gravidez, quando estão relacionados com complicações fetais. Os inibidores específicos de COX-2 devem ser evitados pelo risco de malformação renal. Aspirina em baixa dose pode ser usada seguramente, quando indicada durante a gravidez. Há preferência pelas heparinas de baixo peso molecular, desde que a não fracionada apresente maior risco de induzir trombocitopenia e sangramento. A hidroxicloroquina é usada e de fato recomendada em gestantes com lúpus, com benefícios para a paciente e sem risco fetal. Varfarina é teratogênica se usada da 6ª a 9ª semana de gestação, mas pode ser usada durante o segundo e terceiro trimestres até a 34ª semana, quando deve ser interrompida com o intuito de evitar sangramento fetal. A imunoglobulina endovenosa é recomendada em casos difíceis de síndrome do anticorpo antifosfolipídeo e vem sendo estudada na prevenção do bloqueio cardíaco total da síndrome do lúpus neonatal. O uso de prednisona e prednisolona é limitado a menor dose eficaz, não atinge a circulação fetal, mas pode induzir os efeitos colaterais maternos já conhecidos. Azatioprina e ciclosporina são utilizadas, quando indicadas formalmente, sem aparente risco fetal. Metotrexato e leflunomide devem ser evitados a qualquer custo e o tratamento interrompido três meses antes da tentativa de concepção. Todas as decisões terapêuticas em pacientes grávidas devem ser individualizadas e os riscos e benefícios considerados.The prescription of anti-rheumatic drugs in fertile patients should take into account the current knowledge about their effects on conception, pregnancy and lactation. Judicious advice and pregnancy planning is ideal when possible. With the incorporation of new substances and the constant appearance of recent data in the literature this subject has to be continuously updated. The FDA risk factor rating is sometimes contradictory to our practice, in part because results from animal studies may not be directly applicable to humans. Biologic response modifiers seem to be safely used during pregnancy, since they are large molecules that are not capable of crossing the placenta. Non-steroidal anti-inflammatory drugs including specific COX-2 inhibitors may impair implantation of the ovum but can be used once pregnancy is under way, they should be avoided after 32 weeks, when there is a relationship with fetal complications. COX-2 inhibitors must be avoided due to its risk of renal mal-formation. Low-dose aspirin can be used safely during pregnancy. Low molecular weight heparins are preferred, since the unfractionated heparins have an increased risk of inducing thrombocytopenia and bleeding. Hydroxychloroquine is used and in fact recommended in lupus pregnancy with patients' benefits and no fetal risk. Warfarin is teratogenic if given between the 6th and 9th gestational weeks, but can be used during the second and third until 34 weeks, when it should be withdrawn in order to avoid the risk of neonatal bleeding. Intravenous immunoglobulin is recommended for difficult antiphospholipid cases and is being studied to prevent the congenital heart block of neonatal lupus. Prednisone and prednisolone use is limited to the least effective dose since they do not reach fetal circulation, but can induce maternal side effects. Azathioprine and cyclosporine are used when necessary with no apparent fetal harm. Methotrexate and leflunomide must be avoided by all means and the treatment stopped three months before conception. Every therapeutic decision for a pregnant patient has to be individualized and the risk and benefits considered.

Acne fulminans is a rare condition and the most severe form of acne. It involves the sudden onset of febrile and multisystemic symptoms, with poor response to ordinary therapy in patients who previously had mild to moderate acne. It is characterized by hemorrhagic ulcerative crusting lesions on the face, chest and upper back. The authors report a case of acne fulminans that was successfully treated with oral prednisone and dapsone.A acne fulminans é uma condição rara e a mais severa forma de acne. Manifesta-se com um quadro agudo, febril e multissistêmico, resistente à terapêutica convencional em doentes com antecedente de acne leve ou moderada. As lesões são caracteristicamente úlcero-hemorrágicas e acometem preferencialmente tórax e face. Os autores relatam um caso de acne fulminans com excelente resposta terapêutica ao tratamento empregado.

Em estudo retrospectivo avaliamos a evolução clínica e eletrencefalográfica das formas criptogênica e sintomática da síndrome de West e analisamos a eficácia do hormônio adrenocorticotrófico, vigabatrina, prednisona, ácido valpróico e nitrazepam no controle dos espasmos. Participaram do estudo 70 pacientes, acompanhados por período maior que 2 anos. Doze (17%) eram criptogênicos e 58 (83%) sintomáticos. O grupo criptogênico apresentou percentagem significativamente maior de pacientes que frequentavam escola regular e desenvolvimento motor normal, melhor controle das crises epilépticas, tendência menor a evoluir para síndrome de Lennox Gastaut e 83,3% tiveram controle completo dos espasmos (72,4% dos pacientes do grupo sintomático obtiveram controle completo dos espasmos). O hormônio adrenocorticotrófico e a vigabatrina foram as drogas mais eficazes, controlando 68,75% e 60% dos espasmos, respectivamente, quando utilizados como droga de primeira escolha e 75% e 50%, respectivamente, como drogas de segunda escolha.In a retrospective study we assessed the outcome of the criptogenic and symptomatic forms of West syndrome and evaluated the efficacy of adrenocorticotropic hormone, vigabatrin, prednisone, valproate and nitrazepam in the spasms control. Seventy patients were follwed up by 2 years. Twelve (17%) were criptogenics and 58 (83%) symptomatics. In criptogenic group significantly more patients were in regular school classes and with normal motor development, better control of seizure, less tendency to evoluate to Lennox Gastaut syndrome and 83.3% had control of spasms (72.4% of patients from symptomatic group had control of spasms). Adrenocorticotropic hormone and vigabatrin were the most efective drugs, with 68.75% and 60% of spasms control, respectivelly, when used as first line of therapy and 75% and 50%, respectivelly, as second line of therapy.

A síndrome de Tolosa-Hunt (STH) consiste de oftalmoplegia dolorosa relacionada a processo inílamatório granulomatoso no seio cavernoso. Seu diagnóstico só pode ser firmado quando outras causas potenciais de oftalmoplegia dolorosa forem descartadas. Resposta satisfatória e padronizada a corticosteróides, associada a evolução benigna, pode reforçar essa possibilidade, embora pseudotumor orbitário e neoplasias do tipo linfoma e até meningioma possam suscitar dúvidas no diagnóstico diferencial, pois também podem apresentar boa resposta a essa medicação. Faz-se necessário, portanto, ampla investigação complementar. Apresentamos estudo clínico-radiológico-laboratorial de cinco pacientes com STH. Prednisona foi utilizada em doses entre 40 e 80 mg/dia. Houve resposta analgésica excelente, com remissão da dor em menos de 48 horas em 4 pacientes. Houve melhora mais lenta da oftalmoplegia, que regrediu completamenteentre 4 e 45 dias em todos os pacientes.The Tolosa-Hunt syndrome (THS) consists of a painful ophthalmoplegia related to granulomatous inflammatory process in the cavernous sinus. According to recent concepts, the diagnosis is established only when other causes of painful ophthalmoplegia are ruled out. A typical pattern of response to corticosteroids associated with a benign evolution may reinforce this possibility. Tumors such as lymphoma and meningioma and orbital pseudotumors can make difficult the differential diagnosis because they also may respond to steroids. Thus it is always necessary to make an extensive ancillary investigation. We performed a clinical, laboratory and radiologic study of five patients with THS. Prednisone was used in all, with dosages ranging from 40 to 80 mg/day. In four patients there was a dramatic analgesic effect in less than 48 hours. Improvement of the ophthalmoplegia was not so fast but occurred in all with a complete remission in 4 to 45 days.

It mentions that for the collection cerebrospinal fluid, bone marrow and blood samples of the animals were anesthetized.

Budesonide is a glucocorticoid characterized by its local action, with a low systemic bioavailability. Since the original trial comparing budesonide with prednisone in 2010, it is recommended as an effective alternative for the treatment of non-severe acute or chronic autoimmune hepatitis. In this document, we review the general pharmacologic properties of glucocorticoids, the available evidence for the use of budesonide as first line option for autoimmune hepatitis as well as the safety profile of the drug., (Copyright © 2021 Elsevier España, S.L.U.

OBJETIVO: chamar a atenção para o diagnóstico da doença de Devic e realizar revisão da literatura. DESCRIÇÃO: paciente de 6 anos, do sexo masculino, apresentou subitamente paresia nos membros inferiores, que desapareceu no decorrer da internação. No entanto, à medida que a paresia desaparecia, ocorria perda da visão. Os sintomas só foram revertidos após o uso de prednisona. COMENTÁRIOS: a abordagem diagnóstica e terapêutica foi semelhante à usada em outros casos em diferentes centros de referência, ou seja, o diagnóstico foi clínico e o tratamento com prednisona, obtendo-se a melhora completa dos sintomas. Apesar disso, várias contradições ainda cercam essa doença, desde a etiologia até sua relação com outras doenças desmielinizantes, como a esclerose múltipla.OBJECTIVE: to report a case of Devic disease, emphasizing its diagnosis, in addition to reviewing the medical literature. DESCRIPTION: male, six-year-old patient suddenly developed weakness in lower limbs, with resolution during hospital stay. However, as the weakness disappeared, loss of vision occurred. The symptoms were reverted after the use of prednisone. COMMENTS: the diagnostic and therapeutic approach was similar to that used in other cases reported by different reference centers. In other words, clinical diagnosis and prednisone therapy were used, with the complete improvement of symptoms. However, there is still some controversy surrounding its etiology and relationship with other demyelinating diseases, such as multiple sclerosis.

Se informó de 1 paciente con acné conglobata de aproximadamente 3 años de diagnóstico, presentó agravamiento de sus lesiones, toma del estado general, fiebre, anemia, pérdida de peso, eritro acelerado y pruebas funcionales hepáticas alteradas; lo cual se interpretó como un acné fulminans. Se trató con esteroides y antibióticos, así como con cirugía e injerto de las lesionesA patient was reported to have acne conglobata diagnosed three years ago approximately. He presented with worsening of his lesions, deteriorated general condition, fever, anemia, weight loss, accelerated erythrosedimentation and altered hepatic functional tests, all this was considered to be an indicator of a case of acne fulminans. The patient was treated with steroids and antibiotics as well as surgery and grafting

Descrevemos dois casos clínicos de paraparesia espástica tropical/mielopatia associada ao HTLV-I, obedecendo os critérios da OMS-1989. Estes são os primeiros casos diagnosticados em Cuiabá. Em um dos casos houve resposta clínica ao uso de prednisona.

Introducción: la parálisis de Bell es una afección frecuente que presenta en 15% de los casos una recuperación incompleta. En los últimos años se ha acumulado evidencia del posible rol del virus herpes simple tipo 1 en su etiología. Objetivos: comparar la eficacia de valaciclovir y prednisona versus prednisona placebo en la parálisis de Bell. Material y método: se realizó un ensayo prospectivo, randomizado y placebo controlado. De los 41 pacientes incluidos, 21 fueron tratados con valaciclovir 2 g día durante siete días más prednisona (PV) y 19 con prednisona más placebo (PP) administrados oralmente. Los controles clínicos se realizaron a las 2, 4, 8 y 12 semanas, los pacientes con recuperación incompleta fueron seguidos durante seis meses. La recuperación fue definida como satisfactoria con un puntaje mayor a 90 usando una escala compuesta de parálisis facial (FGS). Resultados: la evolución de la escala de parálisis facial no mostró diferencias significativas entre ambos grupos. La recuperación a los seis meses fue de 86,4% en el grupo PV y 89,5% en el grupo PP (p=0,86). El tiempo medio de recuperación en días fue 70,2 y 71,1, respectivamente (p=0,88). Conclusiones: nuestros resultados no demuestran un beneficio adicional del valaciclovir en el tratamiento de la parálisis de Bell. De acuerdo con las evidencias actuales, no hay consenso respecto al uso rutinario de antivirales en todos los caso de parálisis de Bell (NCT00561106).
