ABSTRACT

Thalidomide and its derivatives have been used in the treatment of myelodysplastic syndrome (MDS) because of their anti-angiogenic and immunomodulatory effects. In recent years, some studies have found that thalidomide and its derivatives not only showed significant efficacy in lower-risk MDS patients with del (5q), but also showed advantages in non-del (5q) MDS patients. In addition, the discovery of its molecular targets and new substrates makes it possible to develop a new generation of immunomodulatory drugs (IMiDs) and to design IMiDs-based proteolysis-targeting chimeras. In this review, the new progress in mechanism and clinical application of thalidomide and its derivatives were summarized briefly, so as to provide a more scientific, reasonable and effective scheme to the treatment of MDS.

ABSTRACT

Abstract: Necrobiotic xanthogranuloma is a rare chronic condition, belonging to the group C non-Langerhans cell histiocytoses, which is relevant due to the possibility of extracutaneous involvement and association with systemic diseases, particularly hematologic malignancies. The case reported here was only diagnosed after nine years of evolution and was associated with plasma cell dyscrasia. After treatment with cyclophosphamide, dexamethasone, and thalidomide, there was a reduction of cutaneous lesions and serum levels of monoclonal protein.

ABSTRACT

Abstract INTRODUCTION: Thalidomide, used to treat erythema nodosum leprosum (ENL), is associated with severe adverse events (AEs) and is highly teratogenic. METHODS: A cross-sectional study was conducted on thalidomide-treated patients with ENL. AEs and selected variables were investigated through interviews and assessment of medical records. Odds ratios with 95% confidence intervals were estimated via logistic regression. RESULTS: Peripheral neuropathy symptoms and deep vein thrombosis (DVT) were the most common AEs reported. Although women of reproductive age used contraceptives, <50% of patients reported using condoms. Polypharmacy was associated with all endpoints, except DVT. CONCLUSIONS: Pharmacovigilance is crucial to prevent harmful thalidomide-associated AEs.

ABSTRACT

Abstract: Zoon's plasma cell balanitis is a chronic genital inflammatory dermatosis that affects uncircumcised men, especially the elderly. It's characterized by painless erythematous plaques of orange hue, located on the glans penis and foreskin. Circumcision is the most effective treatment; however, it can be hard for patients to accept. As an alternative, topical calcineurin inhibitors are used, with good response. This article reports the case of a 32-year-old patient, HIV carrier, diagnosed with Zoon's plasma cell balanitis. Treatment with topical tacrolimus was administered, without improvement. A 6-week course of thalidomide resulted in complete remission of the lesions, without recurrence after eight months of follow-up.

ABSTRACT

Abstract: Atopic dermatitis is a common inflammatory skin disease. New understanding in disease pathogenesis has led to a considerable number of promising new drugs in development. New topical agents can be especially helpful for children, providing an alternative to the need for chronic topical corticosteroid use. While many patients with mild or moderate disease can be managed with topical treatments, there are unmet needs for recalcitrant and severe cases. New and developing therapies hold promise for real advances in management of this complex disease.

ABSTRACT

In the present study, we successfully developed a docetaxel (DTX) and thalidomide (TDD) co-delivery system based on low density lipoprotein (LDL) modified silica nanoparticles (LDL/SLN/DTX/TDD). By employing the tumor homing property of LDL and the drug-loading capability of silica nanoparticles, the prepared LDL/SLN/DTX/TDD was expected to locate and specifically deliver the loaded drugs (DTX and TDD) to achieve effective chemotherapy of liver cancer. In vitro analysis revealed that nano-sized LDL/SLN/DTX/TDD with decent drug loading capabilities was able to increase the delivery efficiency by targeting the low density lipoprotein receptors, which were overexpressed on HepG2 human hepatocellular liver carcinoma cell line, which exerted better cytotoxicity than unmodified silica nanoparticles and free drugs. In vivo imaging and anti-cancer assays also confirmed the preferable tumor-homing and synergetic anti-cancer effects of LDL/SLN/DTX/TDD.

ABSTRACT

El eritema polimorfo solar es la fotodermatosis más frecuente y suele aparecer en primavera con la primera exposición intensa al sol. Sus manifestaciones cutáneas son variadas y el diagnóstico se basa en la clínica junto al antecedente de exposición solar. En los casos leves, la fotoprotección suele ser suficiente para el control de la enfermedad, pero en formas más graves se requieren otras terapéuticas, como corticoides, antihistamínicos, o fototerapia, que genera una "fotoadaptación" de las áreas de piel afectadas. Presentamos un caso típico de erupción polimorfa solar que respondió de forma adecuada a medidas de fotoprotección. (AU)


The polymorphic solar eruption is the most frequent photodermatosis, and usually appears in spring with the first intense exposure to the sun. It has multiple cutaneous manifestations, and its diagnosis is based on the clinic and the antecedent of solar exposition. In mild cases, photoprotection is usually enough to control the disease, but in more severe forms, other therapies are required, such as corticosteroids, antihistamines, or phototherapy to generate a "photo-adaptation" of the affected skin areas. We present a typical case of polymorphic solar eruption that responded adequately to photoprotection measurements. (AU)

ABSTRACT

Abstract: One of the biggest challenges in treating leprosy is the control of reaction events. Patients with lepromatous leprosy may present reaction type II, or erythema nodosum leprosum, during treatment, and this reaction can remain in a recurrent form after being released from the hospital, requiring the use of thalidomide and/or prednisone for long periods of time, in turn increasing the risk of side effects. Two reports of the use of antiTNF to treat erythema nodosum leprosum were found in the literature. A good response was found after an assay with infliximab and etanercept. This study reports on a patient with lepromatous leprosy and recurrent reaction, controlled by using etanercept and a 10-month follow-up, with the interruption of thalidomide and the maintenance of prednisone at 10 mg/day.

ABSTRACT

Solitary extramedullary plasmacytomas represent 3% of plasma cell neoplasms. Their most common locations are the upper gastrointestinal and respiratory tract. We report a 70-year-old male presenting with progressive dyspnea and cough. A chest radiography showed widened mediastinum. Chest computed tomography showed a mediastinal mass. A bronchoscopy showed an extrinsic compression and complete occlusion of the primary bronchus. A self-expandable prosthesis was installed in left bronchus. A population of plasmacytoid cells was evidenced in the mass biopsy. Immunohistochemistry revealed CD20+ and CD138+. These tumor cells stained positively for lambda light chains, but negatively for kappa chains. Therefore an extramedullary plasmacytoma was diagnosed. A multiple myeloma was discarded with a normal blood count, serum calcium and creatinine levels. Serum protein electrophoresis had a monoclonal spike, serum IgG was 1963 mg/dl. Bone marrow aspiration had 1% of plasma cells. Bone x-rays were normal. Computed tomographies of the neck, thorax, abdomen and pelvis ruled out other plasmacytomas. Eight cycles of chemotherapy with thalidomide, melphalan and prednisone were indicated, obtaining complete remission of the tumor. The review of the literature shows that mediastinal extramedullary plasmacytomas are extremely rare. They generally appear in men aged between 50 and 60 years. The treatment of choice is radiotherapy, but given the location in the present case, chemotherapy was considered the best option. Recurrence is approximately 10 to 30% and 10% of patients progress to myeloma, thus requiring close monitoring.

ABSTRACT

Abstract Leprosy is a chronic disease characterized by manifestations in the peripheral nerves and skin. The course of the disease may be interrupted by acute phenomena called reactions. This article reports a peculiar case of type 2 leprosy reaction with Sweet's syndrome-like features as the first clinical manifestation of leprosy, resulting in a delay in the diagnosis due to unusual clinical presentation. The patient had clinical and histopathological features reminiscent of Sweet's syndrome associated with clusters of vacuolated histiocytes containing acid-fast bacilli isolated or forming globi. Herein, it is discussed how to recognize type 2 leprosy reaction with Sweet's syndrome features, the differential diagnosis with type 1 leprosy reaction and the treatment options. When this kind of reaction is the first clinical presentation of leprosy, the correct diagnosis might be not suspected clinically, and established only with histopathologic evaluation.

ABSTRACT

Problema de investigación: Estimar para el caso colombiano, la RICE de lenalidomida más terapia de soporte comparada con terapia de soporte sin lenalidomida para pacientes adultos con SMD y Del 5q en Colombia.Tipo de evaluación económica: Análisis de costo-efectividad (ACE). Población objetivo: Pacientes adultos con SMD y Del 5q en Colombia. Intervención y comparadores: Intervención: lenalidomida (10 mg/día) más terapia de soporte.\r\nHorizonte temporal: Un (1) año. Perspectiva: La perspectiva de análisis es la del Sistema General de Seguridad Social en Salud (SGSSS). Tasa de descuento: No se aplicó tasa de descuento para costos ni para desenlaces en salud debido a que el horizonte temporal es de un año. Estructura del modelo: Para capturar las principales características del SMD y Del 5q se desarrolló un modelo de Markov con probabilidades de transición basadas en el estado de transfusión del paciente, la progresión a LMA y la muerte. La duración del cada ciclo (28 días) se basa en el intervalo de dosificación para lenalidomida. Fuentes de datos de efectividad y seguridad: Los datos de efectividad y seguridad para la elaboración del modelo se obtuvieron del ensayo clínico Fase III MDS-004, el único identificado de este tipo que compara el uso de lenalidomida contra placebo en pacientes con SMD y Del 5q dependientes de transfusión. Desenlaces y valoración: Como unidad natural de desenlace se tomó la proporción de pacientes que alcanzan independencia de transfusión de sangre por un mínimo de 8 semanas consecutivas. Costos incluidos: Se consideran eventos generadores de costos todos los recursos directos asociados al uso de las tecnologías evaluadas. Fuentes de datos de costos: SISMED 2015, Manual de Tarifas ISS 2001 + 30%, Circular No. 02 de 2015 de la Comisión Nacional de Precios de Medicamentos y Dispositivos Médicos, 4 laboratorios clínicos y 2 hemocentros del país. Resultados del caso base: La alternativa de lenalidomida más terapia de soporte es una opción costo-efectiva comparada con la terapia de soporte sin lenalidomida para el tratamiento de SMD y Del 5q en Colombia. \r\nAnálisis de sensibilidad: El análisis de sensibilidad determinístico muestra que los resultados del caso base no son sensibles a variaciones en los costos, aunque cambios en las efectividades pueden alterar esta conclusión. El análisis de sensibilidad probabilístico muestra que, con una probabilidad del 98%, la alternativa de lenalidomida más terapia de soporte sería costo-efectiva para todos los umbrales superiores a $6.345.981,2. Conclusiones y discusión: Es razonable incorporar en el POS la alternativa de lenalidomida más terapia de soporte para el tratamiento de SMD y Del 5q. Esta recomendación obedece a que la tecnología evaluada es costo-efectiva, pero sobre todo a que los pacientes a quienes se les administre esta opción de tratamiento pueden experimentar una mejoría significativa en su calidad de vida.(AU)

ABSTRACT

Abstract BACKGROUND: Actinic prurigo is an idiopathic photodermatosis, the pathophysiology of which has been hypothesized to involve subtype IV type b (Th2) hypersensitive response, whereby IL4, IL5, and IL13 are secreted and mediate the production of B cells, IgE, and IgG4. OBJECTIVES: To examine the association of serum IgE levels and the clinical severity of injuries. METHODS: This case-control study comprised patients with a clinical and histopathological diagnosis of actinic prurigo, as well as clinically healthy subjects, from whom 3cc of peripheral blood was taken for immunoassay. Cases were classified by lesion severity as mild, moderate, and severe. Descriptive statistics were analyzed, and chi-square test was performed. RESULTS: We included 21 actinic prurigo patients and 21 subjects without disease; 11 patients with actinic prurigo had elevated serum IgE levels, and 10 had low serum levels. Six actinic prurigo (AP) patients with elevated serum levels of IgE had moderate injuries, 4 had severe injuries, and 1 had minor injuries. Eight out of 10 patients with normal IgE levels presented with minor injuries in the clinical evaluation. The 21 controls did not have increased serum IgE levels. CONCLUSIONS: Elevated IgE levels are associated with moderate to severe clinical lesions, suggesting that actinic prurigo entails a type IV subtype b hypersensitivity response in which Th2 cells predominate.

ABSTRACT

CONTEXT: Refractory acute myeloid leukemia (AML) is a difficult disease to control with second or third-line chemotherapy regimens. In this report, we describe using azacitidine in combination with lenalidomide as salvage therapy. CASE REPORT: 52-year-old female was diagnosed with refractory AML and high-risk cytogenetics: complex monosomal karyotype consisting of t (3, 3) in association with monosomy 7 and del 5q. Morphological remission associated with maintenance of the cytogenetic abnormality of chromosome 3 and disappearance of the abnormalities relating to chromosomes 5 and 7 was achieved after three cycles of combination therapy with azacitidine and lenalidomide. CONCLUSION: Azacitidine plus lenalidomide can be a therapeutic option for patients with refractory AML, as illustrated in this case. .


CONTEXTO: A leucemia mieloide aguda (LMA) refratária é considerada doença de difícil controle com regime quimioterápico de segunda ou terceira linha. Neste relato, é descrito o uso de azacitidina em combinação com lenalidomida como esquema de resgate. RELATO DE CASO: Paciente de 52 anos, do sexo feminino, com o diagnóstico de LMA refratária de alto risco citogenético, apresentava cariótipo complexo e monossômico, com t (3, 3), associado à monosomia do 7 e del 5q. Destaca-se que, após três ciclos da terapia combinada com azacitidina e lenalidomida, houve remissão morfológica, com manutenção da anormalidade citogenética relacionada ao cromossomo 3 e desaparecimento da anormalidade relacionada aos cromossomos 5 e 7. CONCLUSÃO: Azacitidina e lenalidomida podem ser opção terapêutica para pacientes com LMA refratária, como demonstrado neste caso. .

ABSTRACT

Introducción: los síndromes mielodisplásicos (SMD) representan un grupo de neoplasias hematológicas de las células progenitoras hematopoyéticas que comparten características comunes como la presencia de citopenias y un riesgo variable de evolucionar a leucemia mieloblástica aguda (LMA). Se origina a partir de células madre hematopoyéticas con aberraciones genéticas adquiridas, dentro de las cuales se encuentra la deleción aislada del 5q, presente en aproximadamente el 10% de los casos y que se caracteriza por un curso benigno y de bajo riesgo. El objetivo terapéutico en los pacientes con SMD de alto riesgo es modificar la historia natural de la enfermedad y prolongar la supervivencia, y en los pacientes con SMD de bajo riesgo, mejorar la sintomatología y la calidad de vida. Objetivo: evaluar los beneficios y riesgos del uso de lenalidomida para el tratamiento de pacientes con síndrome mielodisplásico y deleción 5q. Metodología: se realizó una búsqueda de evidencia en las bases de datos: MEDLINE, EMBASE, la Librería Cochrane, LILACS, CENTRAL y en el Registro International de ensayos clínicos. Dos evaluadores de manera independiente, tamizaron las referencias obtenidas, resolviendo las discrepancias por consenso. La calidad de los estudios seleccionados fue evaluada empleando la herramienta de riesgo de sesgo de la colaboración Cochrane. Resultados: se identificó un único ensayo clínico aleatorizado, controlado fase 3 y 4 ensayos clínicos fase 2.

ABSTRACT

The use of thalidomide was never discontinued in Brazil where it is prescribed for leprosy type 2 reaction. Babies with birth defects compatible with the thalidomide embryopathy phenotype were born after 1965, an indication that control on drug dispensing and use failed in the country. The article reports data on thalidomide dispensing and clinical uses in the Federal District in 2011/12, when new rules were put into effect, and data on drug dispensing and use obtained ten years earlier. It was found that the number of patients making use of thalidomide declined from 819 in 2001 to 369 in 2011/12. Leprosy accounted for over 70% of prescriptions in both time periods analyzed in this study. In the same time interval, however, use for lupus erythematosus decreased from 13.7 to 4.9%, while that for multiple myeloma increased from 2.9 to 20.3% of all prescriptions. Thalidomide prescription for the remaining approved indications was far less frequent, and so was the use for off label indications that accounted for <1% of prescriptions in 2001 and 2011/12. Registration of prescribing doctors, patients and dispensing units at the state department of health, apparently rendered this control more effective and reliable.


O uso da talidomida nunca foi interrompido no Brasil, sendo prescrita para tratar a reação tipo 2 da hanseníase. Crianças com defeitos congênitos compatíveis com o fenótipo da embriopatia causada pela talidomida nasceram após 1965, evidenciando que o controle do uso e da dispensação do medicamento falhou no país. O artigo relata dados sobre a dispensação e usos clínicos da talidomida no Distrito Federal em 2011/12, quando a nova regulamentação passou a vigorar, e dados sobre a dispensação e uso do medicamento 10 anos antes. Os resultados mostraram que o número de pacientes que usaram talidomida decresceu de 819 em 2001 para 369 em 2011/12. A hanseníase foi a indicação clínica para mais de 70% das prescrições nos períodos analisados no estudo. No mesmo período, entretanto, o uso para lupus eritematoso reduziu de 13,7 para 4,9%, enquanto o uso para mieloma múltiplo cresceu de 2.9 para 20,3% de todas as prescrições. A prescrição de talidomida para as outras indicações aprovadas foi muito menor, enquanto para indicações não aprovadas correspondeu a < 1% das prescrições em 2001 e 2011/12. O cadastro dos prescritores, pacientes e unidades dispensadoras na secretaria estadual de saúde, aparentemente tornou esse controle mais eficiente e confiável.
