Supervivencia de la ciclosporina en el tratamiento de la dermatitis atópica moderada-grave: Registro Español de Dermatitis Atópica (BIOBADATOP) / Drug Survival in Cyclosporine Treatment for Moderate to Severe Atopic Dermatitis: Analysis of the Spanish Atopic Dermatitis Registry (BIOBADATOP)

Antecedentes: Debido a la eclosión en el último quinquenio de nuevas alternativas terapéuticas para la dermatitis atópica (DA), nos planteamos estudiar la supervivencia actual de la ciclosporina (CsA) en esta patología. La CsA, como paso necesario solicitado por el Sistema Nacional de Salud de España para la autorización de otros tratamientos sistémicos, podría presentar una supervivencia menor que en otras enfermedades. Material y método: Estudio multicéntrico, observacional, de cohortes prospectivo para el que se recogieron pacientes incluidos en el Registro Español de Dermatitis Atópica (BIOBADATOP). Como cohorte de comparación se emplearon los datos del Registro Español de tratamientos sistémicos en Psoriasis (BIOBADADERM). Resultados: Se incluyeron 130 pacientes diagnosticados de DA que habían recibido CsA (mediana de supervivencia de CsA: 1 año). En el grupo comparador se incluyeron 150 pacientes psoriásicos que habían recibido CsA (mediana de supervivencia: 0,37 años). Observamos una mayor supervivencia de la CsA en los pacientes con DA en comparación con los pacientes psoriásicos (p<0,001). Conclusión: La supervivencia de la CsA en BIOBADATOP es similar a la descrita en otras series de pacientes con DA, y superior a la observada en los pacientes con psoriasis en el registro BIOBADADERM.(AU)

Background: The past 5 years have seen a proliferation of new treatments for atopic dermatitis (AD). We analyzed recent drug survival data for cyclosporine in this setting. Because the Spanish National Healthcare system requires patients with AD to be treated with cyclosporine before they can be prescribed other systemic treatments, drug survival for cyclosporine may be shorter than in other diseases. Material and method: Multicenter, observational, prospective cohort study using data from the Spanish Atopic Dermatitis Registry (BIOBADATOP). Data from the Spanish Registry of Systemic Treatments in Psoriasis (BIOBADADERM) were used to create a comparison cohort. Results: We analyzed data for 130 patients with AD treated with cyclosporine (median drug survival, 1 year). Median cyclosporine survival in the psoriasis comparison group (150 patients) was 0.37 years. Drug survival was significantly longer in AD than in psoriasis (P<.001). Conclusion: Drug survival of cyclosporine in the BIOBADATOP registry is similar to that described in other series of patients with AD and longer than that observed in the BIOBADADERM psoriasis registry.(AU)

20% Autologous serum vs. 0.05% cyclosporine and preservative-free artificial tears in the treatment of Sjögren related dry eye / Soro autólogo a 20% versus ciclosporina a 0,05 e lubrificantes oculares sem conservantes no tratamento da síndrome do olho seco relacionada à Sjögren

ABSTRACT Purpose: To compare the 3-month results of treatment with 20% autologous serum or combination treatment with preservative-free artificial tears and 0.05% cyclosporine in patients with dry eye disease due to primary Sjögren's syndrome. Methods: A total of 130 eyes of 65 patients with newly diagnosed dry eye disease due to primary Sjögren's syndrome were included in the study. The patients were divided into two treatment groups: 66 eyes of 33 patients were assigned to the autologous serum treatment group, and 64 eyes of 32 patients were assigned to the combination treatment group. Schirmer test, tear break-up time and Ocular Surface Disease Index (OSDI) scores were recorded at pretreatment and at 3 months of treatment. Results: At 3 months of treatment, the mean Schirmer value and the mean tear break-up time were significantly higher in the combination treatment group (p<0.0001 and p=0.034, respectively). The OSDI score at 3 months was significantly lower in the autologous serum Group (p=0.004). When the two groups were evaluated separately, the improvements in Schirmer, tear break-up time test, and OSDI scores from before to after treatment were statistically significant: p<0.0001, p<0.001, and p<0.0001, respectively, for the authologus serum Group, and p<0.0001, p<0.001, and p<0.0001, respectively, for the combination treatment group. Conclusions: In short-term treatment of dry eye disease due to primary Sjögren's syndrome, treatment with autologous serum was significantly superior to -combination treatment with preservative-free artificial tears and 0.05% cyclosporine in terms of improvement in OSDI scores. Improvements in Schirmer test and tear break-up time scores were significantly superior in the group treated with preservative-free artificial tears and 0.05% cyclosporine.

RESUMO Objetivo: Comparar os resultados de 3 meses de soro autólogo a 20% com um tratamento combinado, ou seja, lubrificantes oculares sem conservantes e ciclosporina a 0,05% em pacientes com síndrome do olho seco devida à síndrome de Sjögren primária. Métodos: Foram incluídos no estudo 130 olhos de 65 pacientes recentemente diagnosticados com síndrome do olho seco devida à síndrome de Sjögren primária. Os pacientes foram divididos em dois grupos de tratamento, 66 olhos de 33 pacientes foram incluídos no grupo de tratamento com soro autólogo e 64 olhos de 32 pacientes foram incluídos no grupo de tratamento combinado com lubrificantes oculares sem conservantes e ciclosporina. Os resultados do teste de Schirmer e do tempo de ruptura do filme lacrimal e os índices de doença da superfície ocular (OSDI) foram registrados antes e depois de três meses de tratamento. Resultados: Três meses após o tratamento, o valor médio do teste de Schirmer foi mais alto com significância estatística no grupo do tratamento combinado com lubrificantes oculares sem conservantes e ciclosporina (p<0,0001) e o tempo de ruptura do filme lacrimal também foi significativamente maior nesse grupo (p=0,034). Também aos três meses, a doença da superfície ocular foi menor com significância estatística no grupo de tratamento com soro autólogo (p=0,004). Quando os dois grupos foram avaliados separadamente, a melhora no teste de Schirmer, o tempo de ruptura e a doença da superfície ocular antes e depois do tratamento tiveram diferenças estatisticamente significativas tanto no grupo de soro autólogo (p<0,0001, p<0,001 e p<0,0001, respectivamente) quanto no grupo de tratamento combinado (p<0,0001, p<0,001 e p<0,0001, respectivamente). Conclusões: No tratamento de curto prazo da síndrome do olho seco devida à síndrome de Sjögren primária, o tratamento com soro autólogo foi significativamente superior ao tratamento com lubrificantes oculares sem conservantes combinados com ciclosporina, em termos de melhora no doença da superfície ocular. As melhoras no teste de Schirmer e no tempo de ruptura do filme lacrimal foram significativamente maiores no grupo de tratamento combinado com lubrificantes oculares sem conservantes e ciclosporina.

Severe and life-threatening onset of systemic lupus erythematosus.

Macrophage activation syndrome (MAS) is a potentially life-threatening complication of rheumatic diseases. We report a unique case of a previously healthy 20-year-old female presenting with MAS as first presentation of systemic lupus erythematosus. Remission was achieved with hydroxychloroquine, intravenous methylprednisolone pulse followed by oral prednisolone and cyclosporine. However, the management of MAS is still challenging, and the mortality rate remains high.

Cyclosporine induced generalized hyperkeratosis in a dog.

INTRODUCTION: Cyclosporine is a potent immunosuppressive agent used in veterinary medicine to treat a variety of inflammatory or immune mediated conditions. Many adverse effects are associated with this medication, however most of them rarely occur. A 5-year-old, female intact French bulldog was presented with multiple, multifocally distributed, severe hyperkeratotic and papillomatous/verrucous plaques. The dog was on long-term immunosuppressive treatment with cyclosporine for meningoencephalitis of unknown origin (MUO). It had an history of atopic dermatitis and calcinosis cutis. A papillomavirus infection was excluded by polymerase chain reaction (PCR), and histopathologic analysis revealed a chronic lymphoplasmacytic non-specific dermatitis, perifolliculitis and periadnexitis and focal folliculitis with papillomatous epidermal hyperplasia and orthokeratotic hyperkeratosis. The diagnosis of "cyclosporine-induced epidermal hyperplasia with secondary pyoderma" was made. Cyclosporine was discontinued and as an alternative mycophenolate mofetil was started to control the MUO. An antimicrobial treatment was prescribed for three weeks. After four months, the skin lesions had healed completely. To date after 2 years, the dog is still in remission. The occurrence of hyperplastic lesions associated with cyclosporine therapy have already been described in previous reports. Most of them resemble those of psoriasiform lichenoid dermatitis, although papilloma virus may be detected in some instances. The dog of the present case showed some peculiarities in the histopathological findings, and a papillomavirus involvement was ruled out with PCR. Like observed in a previous report, there was no correlation between cyclosporine blood level and the severity of dermatological changes. A discontinuation of cyclosporine resulted in complete healing in 4 months. This case highlights the importance of regular monitoring and follow-ups in patients on immunosuppressive therapy. Even rare side effects should always be considered in these cases.

INTRODUCTION: La cyclosporine est un puissant agent immunosuppresseur utilisé en médecine vétérinaire pour traiter une variété de conditions inflammatoires ou à médiation immunitaire. De nombreux effets indésirables sont associés à ce médicament, mais la plupart d'entre eux se produisent rarement. Un bouledogue français intact, âgé de 5 ans, a été présenté avec de multiples plaques hyperkératosiques et papillomateuses/verruqueuses sévères, réparties de manière multifocale. Le chien suivait un traitement immunosuppresseur à long terme à base de cyclosporine pour une méningo-encéphalite d'origine inconnue (MUO). Il avait des antécédents de dermatite atopique et de calcinosis cutis. Une infection à papillomavirus a été exclue par réaction en chaîne par polymérase (PCR) et l'analyse histopathologique a révélé une dermatite chronique lymphoplasmocytaire non spécifique, une périfolliculite et une périannexite ainsi qu'une folliculite focale avec hyperplasie épidermique papillomateuse et hyperkératose orthokératosique. Le diagnostic d'¼hyperplasie épidermique induite par la cyclosporine avec pyodermie secondaire¼ a été posé. La cyclosporine a été stoppée et on a commencé à administrer du mycophénolate mofétil comme alternative pour contrôler l'OMU. Un traitement antimicrobien a été prescrit pendant trois semaines. Après quatre mois, les lésions cutanées étaient complètement guéries. À ce jour, après deux ans, le chien est toujours en rémission. L'apparition de lésions hyperplasiques associées au traitement par la cyclosporine a déjà été décrite dans des rapports précédents. La plupart d'entre elles ressemblent à celles de la dermatite lichénoïde psoriasiforme, bien que le virus du papillome puisse être détecté dans certains cas. Le chien du cas présent présentait quelques particularités dans les résultats histopathologiques et une implication du papillomavirus a été exclue par PCR. Comme observé dans un rapport précédent, il n'y avait pas de corrélation entre le taux sanguin de cyclosporine et la sévérité des altérations dermatologiques. L'arrêt de la cyclosporine a permis une guérison complète en 4 mois. Ce cas souligne l'importance d'une surveillance et d'un suivi réguliers des patients sous traitement immunosuppresseur. Les effets secondaires, même rares, doivent toujours être pris en compte dans ces cas.

Dupilumab, upadacitinib, cyclosporine, and azathioprine are well tolerated and safe

Dermatite atópica grave: guia prático de tratamento da Associação Brasileira de Alergia e Imunologia e Sociedade Brasileira de Pediatria / Severe atopic dermatitis: a practical treatment guide from the Brazilian Association of Allergy and Immunology and the Brazilian Society of Pediatrics

A dermatite atópica (DA) é uma doença cutânea inflamatória, crônica, comum, complexa e de etiologia multifatorial, que se manifesta clinicamente com prurido muitas vezes incapacitante, lesões recorrentes do tipo eczema, xerose e que pode evoluir para liquenificação. Embora o conhecimento sobre a sua fisiopatologia venham crescendo nos últimos anos, ainda as formas graves são frequentes e representam um desafio para o clínico. Para o presente guia realizou-se revisão não sistemática da literatura relacionada à DA grave refratária aos tratamentos habituais com o objetivo de elaborar um documento prático e que auxilie na compreensão dos mecanismos envolvidos na DA, assim como dos possíveis fatores de risco associados à sua apresentação. A integridade da barreira cutânea é um dos pontos fundamentais para a manutenção da homeostase da pele. Além dos cuidados gerais: evitação dos agentes desencadeantes e/ou irritantes, o uso de hidratantes, suporte emocional, entre outros, o uso de agentes anti-inflamatórios/imunossupressores de uso tópico e/ou sistêmico também foi revisado. A aquisição de novos agentes, os imunobiológicos e as pequenas moléculas, melhorou a terapêutica para os pacientes com formas graves de DA, sobretudo as refratárias aos tratamentos convencionais.

Atopic dermatitis is a chronic, common, and complex inflammatory skin disease with a multifactorial etiology. It manifests clinically with often disabling pruritus, recurrent eczema-like lesions, and xerosis, and can progress to lichenification. Although understanding of the disease's pathophysiology has been growing in recent years, severe forms are still frequent and represent a challenge for clinicians. A non-systematic review of the literature on severe atopic dermatitis refractory to conventional treatment was conducted to develop the present guide, whose purpose is to help clarify the mechanisms involved in the disease and possible risk factors. The integrity of the skin barrier is fundamental for maintaining skin homeostasis. In addition to general care, patients should avoid triggering and/or irritating agents and moisturizers and seek emotional support, etc.; the use of topical and/or systemic anti-inflammatory/immunosuppressive agents was also reviewed. New agents, immunobiologicals, and small molecules have led to a broader range of therapies for patients with severe forms of the disease, especially cases refractory to conventional treatment.

Comparative efficacy of three regimens (cyclosporine, tacrolimus, and cyclophosphamide) combined with steroids for the treatment of idiopathic membranous nephropathy.

INTRODUCTION AND OBJECTIVES: To investigate the efficacy of combined immunosuppressive regimens of cyclosporine (CsA), tacrolimus (TAC), or cyclophosphamide (CTX) combined with steroids in the treatment of idiopathic membranous nephropathy (IMN). MATERIALS AND METHODS: A total of 150 biopsy-proven IMN patients were divided into three groups: CTX, TAC, and CsA groups (50 cases each). Patients received a selected regimen for 48 weeks. The efficacy (remission rate, 24h urinary protein, and serum albumin and creatinine) and safety (adverse events) profiles of administered regimens were evaluated at 12, 24 and 48 weeks. RESULTS: At 12 weeks, the response rates for CsA, TAC, and CTX groups were 14%, 50%, and 22%, respectively. This increased to 74%, 84%, and 82%, respectively at 48 weeks. During follow-up, 24h urinary protein significantly reduced from baseline in all regimens (P<0.05), while serum albumin increased in TAC and CTX groups after 12 weeks (P<0.05), and CsA group at 48 weeks (P<0.05). No significant changes in serum creatinine levels were noted in all three regimens (P>0.05). Safety was comparable in all groups, with lower respiratory tract infection being the most frequent adverse event. CONCLUSIONS: The combined regimens (i.e., TAC, CsA, and CTX) are effective in the treatment of patients with IMN at 48 weeks, while TAC and CTX might be more beneficial in terms of shortened time to remission and increased complete response rate.

Introducción y objetivos: Investigar la eficacia de los regímenes inmunosupresores combinados de ciclosporina (CsA), tacrolimús (TAC) o ciclofosfamida (CTX) combinados con esteroides en el tratamiento de la nefropatía membranosa idiopática (NMI). Materiales y métodos: Un total de 150 pacientes con NMI comprobada por biopsia se dividieron en 3 grupos: grupos CTX, TAC y CsA (50 casos cada uno). Los pacientes recibieron un régimen seleccionado durante 48 semanas. Se evaluaron los perfiles de eficacia (tasa de remisión, proteína en orina de 24h y albúmina y creatinina séricas) y seguridad (eventos adversos) de los regímenes administrados a las 12, 24 y 48 semanas. Resultados: A las 12 semanas, las tasas de respuesta para los grupos CsA, TAC y CTX fueron del 14, el 50 y el 22%, respectivamente. Esto aumentó al 74, el 84 y el 82%, respectivamente, a las 48 semanas. Durante el seguimiento, la proteína urinaria de 24h se redujo significativamente desde el inicio en todos los regímenes (p <0,05), mientras que la albúmina sérica aumentó en los grupos TAC y CTX después de 12 semanas (p <0,05) y el grupo CsA a las 48 semanas (p <0,05). No se observaron cambios significativos en los niveles de creatinina sérica en los 3 regímenes (p> 0.05). La seguridad fue comparable en todos los grupos, siendo la infección del tracto respiratorio inferior el evento adverso más frecuente. Conclusiones: Los regímenes combinados (es decir, TAC, CsA y CTX) son eficaces en el tratamiento de pacientes con NMI a las 48 semanas, mientras que TAC y CTX podrían ser más beneficiosos en términos de reducción del tiempo de remisión y aumento de la tasa de respuesta completa.

Evaluation of the impact of subepithelial corneal infiltrates on corneal biomechanics after epidemic keratoconjunctivitis / Avaliação do impacto de infiltrados sub-epiteliais corneanos na biomecânica corneana após ceratoconjuntivite epidêmica

ABSTRACT Purpose: To examine the effect of subepithelial corneal infiltrates on corneal biomechanical properties after epidemic keratoconjunctivitis compared to that in healthy controls. Methods: The cross-sectional study included consecutive patients with bilateral subepithelial corneal infiltrates after epidemic keratoconjunctivitis and healthy controls. Best corrected visual acuity corneal subepithelial infiltrate scoring Fantes grading scale, and central corneal thickness were measured. Corneal hysteresis corneal resistance factor Goldmann correlated intraocular pressure and corneal compensated intraocular pressure were assessed using an ocular response analyzer. Results: This study included 66 eyes of 33 patients with subepithelial corneal infiltrates following epidemic keratoconjunctivitis and randomly selected 37 eyes of 37 healthy volunteers. The mean Fantes and CSIS scores were 1.8 ± 0.8 and 2.9 ± 1.3, respectively, in the first involved eyes and 1.3 ± 1.1 and 1.9 ± 1.7, respectively, in the fellow eyes (p=0.009 and p=0.002, respectively). The first (526.1 ± 28.1 µm; p=0.005) and second involved eyes (523.4 ± 38.1 µm; p=0.044) had significantly thinner corneas compared to that in healthy controls (557.0 ± 38.1 µm). While best-corrected visual acuity showed a positive correlation with corneal resistance factor (r=0.363, p=0.045) and corneal hysteresis (r=0.414, p=0.021), corneal subepithelial infiltrate scoring showed a negative correlation with Goldmann correlated intraocular pressure (r=-0.479, p=0.006) and corneal compensated intraocular pressure (r=-0.413, p=0.021). Conclusion: Eyes with subepithelial corneal infiltrates had significantly thinner corneas compared to that in healthy controls. A positive correlation of the corneal resistance factor and corneal hysteresis with best-corrected visual acuity and a negative correlation of the Goldmann correlated intraocular pressure and corneal compensated intraocular pressure with corneal subepithelial infiltrate scoring should be taken into account when measuring intraocular pressure values in patients with subepithelial corneal infiltrates.

RESUMO Objetivo: Examinar o efeito de infiltrados sub-epiteliais corneanos nas propriedades biomecânicas da córnea após ceratoconjuntivite epidêmica, em comparação com controles saudáveis. Métodos: Este estudo transversal incluiu pacientes consecutivos com infiltrados sub-epiteliais corneanos bilaterais após ceratoconjuntivite epidêmica e controles saudáveis. Foram medidas a melhor acuidade visual corrigida, uma pontuação do infiltrado sub-epitelial da córnea, a escala de graduação de Fantes e a espessura central da córnea. A histerese da córnea, o fator de resistência da córnea, a pressão intraocular correlacionada à tonometria de Goldmann e a pressão intraocular compensada da córnea foram avaliados com o Ocular Response Analyzer. Resultados: Este estudo incluiu 66 olhos de 33 pacientes com infiltrados corneanos sub-epiteliais após ceratoconjuntivite epidêmica e selecionou aleatoriamente 37 olhos de 37 voluntários saudáveis. As pontuações médias da escala de Fantes e dos infiltrados sub-epiteliais corneanos nos primeiros olhos acometidos foram respectivamente de 1,8 ± 0,8 e 2,9 ± 1,3. Nos olhos contralaterais, foram respectivamente de 1,3 ± 1,1 e 1,9 ± 1,7 (p=0,009 e p=0,002, respectivamente). O primeiro e o segundo olhos envolvidos tinham córneas significativamente mais finas (respectivamente 526,1 ± 28,1 µm; p=0,005 e 523,4 ± 38,1 µm; p=0,044) em comparação com os controles saudáveis (557,0 ± 38,1 µm). Embora a acuidade visual melhor corrigida tenha mostrado uma correlação positiva com o fator de resistência da córnea (r=0,363, p=0,045) e com a histerese da córnea (r=0,414, p=0,021), a pontuação dos infiltrados sub-epiteliais corneanos mostrou uma correlação negativa com a pressão intraocular correlacionada à tonometria de Goldmann (r=-0,479, p=0,006) e com a pressão intraocular compensada da córnea (r=-0,413, p=0,021). Conclusão: Os olhos com infiltrados corneanos sub-epiteliais tinham córneas significativamente mais finas em comparação com os controles saudáveis. Ao se medirem os valores de pressão intraocular em pacientes com infiltrados sub-epiteliais corneanos, deve-se levar em consideração tanto as correlações positivas do fator de resistência da córnea e da histerese da córnea com a melhor acuidade visual corrigida quanto as correlações negativas da pressão intraocular correlacionada à tonometria de Goldmann e da pressão intraocular compensada da córnea com a pontuação do infiltrado sub-epitelial da córnea.

Urticária crônica espontânea nos adultos: diagnóstico e terapêutica no presente e futuro. Uma revisão narrativa / Chronic spontaneous urticaria in adults: diagnosis and therapy in the present and future. A narrative review

As urticárias são dermatoses frequentes, acometendo 15% a 20% da população, com pelo menos um episódio agudo da doença na vida. São classificadas em agudas (≤ 6 semanas) ou crônicas (> 6 semanas), de etiologia induzida ou espontânea. A urticária crônica espontânea tem prevalência estimada entre 1% e 2% da população mundial. Apresenta intenso comprometimento da qualidade de vida dos doentes, de forma que afeta várias esferas da vida como relacionamentos interpessoais, perdas laborais, interferência no estudo, perda de sono, entre outras, além de provocar transtornos psiquiátricos em 46% dos doentes pela imprevisibilidade das crises e peso monetário pela perda laboral e custo de tratamento contínuo. Atualmente os anti-histamínicos não sedantes (de segunda geração) constituem a pedra angular no tratamento da urticária crônica espontânea, em decorrência dos seus efeitos reduzidos sobre as atividades cognitivas e outras no sistema nervoso central e cardiovascular. A abordagem terapêutica se inicia com as doses licenciadas pelos fabricantes e é consenso internacional que os anti-histamínicos de segunda geração podem ser usados em doses duplicadas, triplicadas ou quadruplicadas, pois as doses padrão controlam apenas 39% dos doentes. Ainda assim, para grupo substancial dos doentes, torna-se necessária a segunda linha de tratamento, que é o omalizumabe, (um anticorpo monoclonal anti-imunoglobulina E [IgE] e anti-receptor de alta afinidade da IgE nos mastócitos e basófilos). Como terceira linha terapêutica, destaca-se a ciclosporina. Em raros casos refratários às medidas anteriores, há drogas com menor nível de evidência científica disponíveis, as quais são abordadas neste artigo de revisão.

Effect of Tacrolimus and Cyclosporine Immunosuppressants on Peripheral Nerve Regeneration: Systematic Review and Meta-analysis / Efeito dos imunossupressores tacrolimus e ciclosporina na regeneração de nervos periféricos: Revisão sistemática e metanálises

Abstract Peripheral nerve damage is an important cause of seeking medical attention. It occurs when the continuity of structures is interrupted and the propagation of nervous impulses is blocked, affecting the functional capacity of individuals. To assess the effects of the immunosuppressants tacrolimus and cyclosporine on the regeneration of peripheral nerves, a systematic review of the literature was carried out. The articles included were published until September 2018 and proposed to evaluate the effects of the immunosuppressants tacrolimus and cyclosporine on nerve regeneration and neuroprotection, available in the MEDLINE, EMBASE, Cochrane Library, Web of Science, Oxford Pain Relief Database, and LILACS databases. The research analysed a total of 56 articles, of which 22 were included in the meta-analysis. Statistical analysis suggests the protective effect of tacrolimus in the regeneration of the number of myelinated axons (95% confidence interval [CI]: 0.93-2.39; p< 0.01); however, such effect was not observed in relation to cyclosporine (95%CI: - 0.38-1.18; p» 0.08) It also suggests that there is a significant relationship between the use of tacrolimus and myelin thickness (95%CI» 2.00-5.71; p< 0. 01). The use of immunosuppressants in the regeneration of peripheral nerve damage promotes an increase in the number of myelinated axons in general, regardless of the administered dose. In addition, it ensures greater myelin thickness, muscle weight and recovery of the sciatic functional index. However, heterogeneity was high in most analyses performed.

Resumo As lesões nervosas periféricas são uma causa importante de busca por atendimento médico. Elas ocorrem quando há a interrupção da continuidade das estruturas e do bloqueio da propagação dos impulsos nervosos, afetando a capacidade funcional dos indivíduos. Para avaliar os efeitos dos imunossupressores tacrolimus e ciclosporina na regeneração de nervos periféricos, foi realizada uma revisão sistemática da literatura. Foram incluídos artigos publicados até setembro de 2018, que se propunham avaliar os efeitos dos imunossupressores tacrolimus e ciclosporina na regeneração nervosa e neuroproteção, disponíveis nas bases de dados MEDLINE, EMBASE, Cochrane Library, Web of Science, Oxford Pain Relief Database e LILACS. A pesquisa analisou um total de 56 artigos, dos quais 22 foram para metanálise. A análise estatística sugere o efeito protetor do tacrolimus na regeneração do número de axônios mielinizados (intervalo de confiança [IC] 95%: 0,93-2,39; p< 0,01); todavia tal efeito não foi observado em relação à ciclosporina (IC95%: - 0,38-1,18; p» 0,08). Ela também sugere haver uma relação significativa entre o uso do tacrolimus e a espessura da mielina (IC95%: 2,00-5,71; p< 0,01). O uso de imunossupressores na regeneração de lesão nervosa periférica promove um aumento no número de axônios mielinizados de forma geral, independentemente da dose administrada. Além disso, garante uma maior espessura da mielina, um maior peso muscular e restabelecimento do índice da função do nervo ciático. Todavia, a heterogeneidade foi alta na maioria das análises realizadas.

Síndrome DRESS inducido por ácido valproico en una niña que respondió a la ciclosporina con análisis de HLA / Valproic acid-induced DRESS in a child responding to cyclosporine with HLA analysis

El síndrome de erupción medicamentosa con eosinofilia y síntomas sistémicos (drug reaction with eosinophilia and systemic symptoms, DRESS), también conocido como síndrome de hipersensibilidad inducida por medicamentos, es una reacción rara potencialmente mortal que causa una erupción grave y que puede provocar insuficiencia multiorgánica. Como con otras erupciones medicamentosas graves, los linfocitos T específicos para un medicamento tienen una función crucial en el síndrome DRESS. El modelo de hapteno/pro-hapteno, el modelo de interacción farmacológica y el modelo alterado de repertorio de péptidos son tres modelos diferentes desarrollados para describir la relación/interacción entre un medicamento o sus metabolitos y el sistema inmunitario. Analizamos nuestra experiencia con el tratamiento con ciclosporina en un caso de síndrome DRESS resistente a esteroides causado por ácido valproico en una niña y sus resultados clínicos, de laboratorio y de antígeno leucocitario humano (HLA).

Drug reaction with eosinophilia and systemic symptoms (DRESS), also known as drug-induced hypersensitivity syndrome, is a potentially life-threatening rare reaction that causes a severe rash and can lead to multiorgan failure. As in other severe drug eruptions, drug-specific T lymphocytes play a crucial role in DRESS. The hapten/pro-hapten model, pharmacological interaction model, and altered peptide repertoire model are three different models developed to describe the relationship/interaction between a medication or its metabolites and the immune system. We discuss our experience with cyclosporine treatment in a steroid-resistant DRESS syndrome caused by valproic acid in a girl, as well as her clinical, laboratory, and human leukocyte antigens (HLA) study results

In vitro activity of immunosuppressive agents against Cryptococcus neoformans.

INTRODUCTION: Infections caused by Cryptococcus neoformans are a major cause of fungal mortality in HIV-infected/AIDS patients and in those receiving organ transplants. We evaluated the in vitro activity of tacrolimus and cyclosporine in combination with amphotericin B and fluconazole against C. neoformans. METHODS: MICs were determined against a total of 30 clinical isolates of C. neoformans by the microdilution method following the CLSI M27-A3 guidelines and by the checkerboard method. RESULTS: Tacrolimus and cyclosporine A showed in vitro activity against cryptococcal isolates. The combination of amphotericin B with cyclosporine A or tacrolimus was synergistic against 90% and 30% of isolates, respectively. Synergism was also observed with the combination of fluconazole with cyclosporine A or tacrolimus, against 70% and 20% of isolates, respectively. CONCLUSIONS: The synergistic interactions between the calcineurin inhibitors and antifungal drugs against C. neoformans isolates, could potentially have a role in devising novel therapeutic strategies for this opportunistic mycosis.

Comparison of the clinical effects of two different doses (0. 05% and 0. 1%) of topical cyclosporine A in dry eyes with meibomian gland dysfunction / Comparação de efeitos clínicos de duas doses diferentes (0, 05% e 0, 1%) de ciclosporina A tópica em olhos secos com disfunção da glândula tarsal

ABSTRACT Objective: To compare the clinical efficacy of two different doses of topical cyclosporine A used in addition to artificial tears in the treatment of patients with meibomian dysfunction and secondary dry eye. Methods: Fifty patients aged 18 to 40 years, who presented to our clinic between June 2020 and June 2021 were included in our study. Patients were divided into two groups as Group A (topical cyclosporine A 0.05%) and Group B (topical cyclosporine A 0.1%). All the patients underwent a detailed ophthalmological examination, basal Ocular Surface Disease Index measurement, and Schirmer 1 and tear break-up time tests at all visits. Results: The mean age was 32±7.1 years in Group A and 30.7±8.5 years in Group B. In Group A, there were 15 women and ten men, and Group B consisted of 14 women and 11 men. There was no difference between the groups in terms of age and gender distribution (p>0.05). Schirmer 1 and tear break-up time results and Ocular Surface Disease Index score also did not significantly differ between the groups (p>0.05). Conclusion: Cyclosporine A 0.05% and 0.1% eye drops were both seen to be effective in managing dry eye disease in patients with meibomian gland dysfunction.

RESUMO Objetivo: Comparar a eficácia clínica de duas doses diferentes de ciclosporina A tópica utilizada além da lágrima artificial no tratamento de pacientes com disfunção da glândula tarsal e olho seco secundário. Métodos: No estudo, foram incluídos 50 pacientes com idades entre 18 e 40 anos, que se apresentaram em nossa clínica entre junho de 2020 e junho de 2021. Os pacientes foram divididos em dois grupos: Grupo A (ciclosporina A 0,05% tópica) e Grupo B (ciclosporina A 0,1% tópica). Todos os pacientes foram submetidos a um exame oftalmológico detalhado, medição basal do Índice de Doença da Superfície Ocular, e testes de Schirmer 1 e de tempo de ruptura em todas as visitas. Resultados: A idade média foi de 32±7,1 anos no Grupo A e 30,7±8,5 anos no Grupo B. No Grupo A, havia 15 mulheres e dez homens, e o Grupo B consistia de 14 mulheres e 11 homens. Não havia diferença significativa entre os grupos em termos de distribuição por idade e gênero (p>0,05). Os resultados do Schirmer 1 e do tempo de ruptura e do Índice de Doenças da Superfície Ocular também não apresentaram diferença significativa entre os grupos (p>0,05). Conclusão: Observou-se que os colírios de ciclosporina A 0,05% e 0,1% são eficazes no tratamento da síndrome do olho seco em pacientes com disfunção da glândula tarsal.
