RESUMO
Abstract Relapsing polychondritis is a rare multisystem disease involving cartilaginous and proteoglycan-rich structures. The diagnosis of this disease is mainly suggested by the presence of flares of inflammation of the cartilage, particularly in the ears, nose or respiratory tract, and more rarely, in the presence of other manifestations. The spectrum of clinical presentations may vary from intermittent episodes of painful and often disfiguring auricular and nasal chondritis to an occasional organ or even life-threatening manifestations such as lower airway collapse. There is a lack of awareness about this disease is mainly due to its rarity. In 2020, VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome, a novel autoinflammatory syndrome, was described. VEXAS syndrome is attributed to somatic mutations in methionine-41 of UBA1, the major E1 enzyme that initiates ubiquitylation. This new disease entity connects seemingly unrelated conditions: systemic inflammatory syndromes (relapsing chondritis, Sweet's syndrome, and neutrophilic dermatosis) and hematologic disorders (myelodysplastic syndrome or multiple myeloma). Therefore, this article reviews the current literature on both disease entities.

Introduction: Multiple sclerosis is a chronic, inflammatory, demyelinating, autoimmune disease of the central nervous system. It is the first cause of non-traumatic disability in young adults, significantly affecting the quality of life, with physical, social and emotional alterations. Objective: To characterize from the clinical point of view, patients diagnosed with multiple sclerosis. Method: A descriptive and cross-sectional observational study was carried out in a case series of 40 patients, with variables age, sex, comorbidity, initial symptoms, clinical forms and degree of disability. A frequency analysis was carried out. Results: Patients aged between 30 and 39 years (57.5%) predominated. Female patients represented 58.8% of the cases studied and 85.5% presented motor manifestations, as initial symptoms of the disease. Motor symptoms were predominant during the onset of the disease. The most frequent clinical form of multiple sclerosis was relapsing-remitting and the degree of minimal disability. Conclusions: Motor manifestations are the most frequent initial symptoms, as well as the relapsing-remitting clinical form and the minimum degree of disability. The patients are fundamentally female, in the fourth decade of life.
RESUMO
Resumen Antecedentes: La esclerosis múltiple es una enfermedad crónica, autoinmune y degenerativa. Las terapias blanco contra los linfocitos B han probado ser efectivas en su tratamiento; sin embargo, existen pocos estudios que evalúen su eficacia en población mexicana. Objetivo: Evaluar el impacto clínico del rituximab en pacientes con esclerosis múltiple remitente recurrente (EMRR) de reciente diagnóstico. Material y métodos: Estudio de vida real, descriptivo, en el que se evalúa rituximab como tratamiento de EMRR durante un periodo de 24 meses. Se analizaron variables clínicas pre y postratamiento; se realizó la comparación entre pacientes naïve y no naïve. Resultados: Se incluyeron 28 pacientes con EMRR. La edad media al diagnóstico fue de 30.7 años y 22 pacientes fueron naïve (78.5 %). Después de 24 meses, se observó una reducción media de 1.8 puntos en EDSS y en el número de lesiones activas por resonancia magnética. Aunque se logró establecer una diferencia significativa en ambas variables con p < 0.05, el modelo de regresión logística no mostró una relación entre las variables para alcanzar un NEDA-3. No se observaron eventos adversos graves. Conclusiones: El tratamiento con rituximab resultó en mejoría significativa clínica y radiológica en pacientes mexicanos con EMRR naïve y no-naïve.
Abstract Background: Multiple sclerosis is a chronic, autoimmune, degenerative disease. Therapies targeting B-cells have been shown to be effective in its treatment; however, there are few studies evaluating their efficacy in the Mexican population. Objective: To evaluate the clinical impact of rituximab in patients with newly-diagnosed relapsing-remitting multiple sclerosis (RRMS). Material and methods: Real life, descriptive study, in which rituximab was evaluated as treatment for RRMS over a 24-month period. Pre- and post-treatment clinical variables were analyzed; a comparison was made between treatment-naïve and non-treatment-naïve patients. Results: Twenty-eight patients with RRMS were included. Mean age at diagnosis was 30.7 years, and 22 patients were treatment-naïve (78.5 %). After 24 months, there was a mean reduction of 1.8 points in the EDSS scale and a decrease in the number of active lesions on magnetic resonance imaging; a significant difference in both variables could be established (p < 0.05). However, the logistic regression model did not show a relationship between the variables for achieving NEDA-3 criteria. No serious adverse events were observed. Conclusions: Treatment with rituximab resulted in significant clinical and radiological improvement in treatment-naïve and non-treatment-naïve Mexican patients with RRMS.

RESUMO
Objective:To investigate the changes in gray matter volume of the subsystems as well as intra-subsystem and inter-subsystem functional connectivity in the default mode network (DMN) of relapsing-remitting multiple sclerosis (RRMS) patients with preserved cognitive function.Methods:In this prospective study, thirty-seven RRMS patients with preserved cognitive function who were admitted to Huashan Hospital of Fudan University from April 2020 to January 2021 (RRMS group) and 43 healthy volunteers (HC group) were recruited. Patients in the RRMS group received the cognitive assessment using a clinical cognitive functioning scale. Three-dimensional T 1WI and resting-state functional MRI were performed to obtain the brain structural and functional data. The DMN was divided into three subsystems: CORE, dorsal medial prefrontal cortex (DMPFC), and medial temporal lobe (MTL). The gray matter volume of the three subsystems were extracted from the gray matter volume map generated by spatial normalization; 24 regions of interest (ROIs) of the DMN were defined based on Yeo′s 17 networks, and their functional connectivity values were calculated to derive the mean intra-subsystem and inter-subsystem functional connectivity values. Differences in gray matter volume and functional connectivity between the RRMS and HC groups were compared using independent sample t-tests; Spearman′s partial correlation was used to analyze the correlation between subsystems′ gray matter volume and functional connectivity, as well as between subsystems′ functional connectivity and clinical scale scores. Results:Compared to the HC group, the gray matter volume of the three subsystems of the DMN were considerably reduced in the RRMS group ( P<0.05). The functional connectivity within and between the three subsystems were not statistically significantly different between the HC and RRMS groups ( P>0.05). Based on the ROI analysis, patients with RRMS the brain regions with significantly reduced DMN intra-subsystem functional connectivity values were mainly located in the left dorsomedial prefrontal cortex of the DMPFC, the right lateral temporal cortex of the DMPFC, and the left medial temporal cortex of the MTL, as compared with the HC group ( P<0.01). The gray matter volume of DMPFC was positively correlated with the functional connectivity within DMPFC in the control group ( r=0.326, P=0.040). In the RRMS group, the gray matter volume of CORE was positively correlated with the functional connectivity between CORE and DMPFC ( r=0.363, P=0.038), and the functional connectivity within CORE was positively correlated with scores on the memory and executive screening scale ( r=0.430, P=0.036). Conclusions:RRMS patients with preserved cognitive function exhibit gray matter atrophy in all three DMN subsystems. There is no correlation between the structure and function of the DMPFC subsystem. The functional connectivity within CORE subsystem may reflect memory and execution status; DMPFC and CORE may be critical encephalic regions for neurodegeneration and brain functional changes in RRMS patients with preserved cognitive function.
RESUMO
OBJECTIVES@#To investigate the change in the distribution of memory B cell subsets in children with frequently relapsing nephrotic syndrome (FRNS) during the course of the disease.@*METHODS@#A total of 35 children with primary nephrotic syndrome (PNS) who attended the Department of Pediatrics of the Affiliated Hospital of Xuzhou Medical University from October 2020 to October 2021 were enrolled as subjects in this prospective study. According to the response to glucocorticoid (GC) therapy and frequency of recurrence, the children were divided into two groups: FRNS (n=20) and non-FRNS (NFRNS; n=15). Fifteen children who underwent physical examination were enrolled as the control group. The change in memory B cells after GC therapy was compared between groups, and its correlation with clinical indicators was analyzed.@*RESULTS@#Before treatment, the FRNS and NFRNS groups had significantly increased percentages of total B cells, total memory B cells, IgD+ memory B cells, and IgE+ memory B cells compared with the control group, and the FRNS group had significantly greater increases than the NFRNS group (P<0.05); the FRNS group had a significantly lower percentage of class-switched memory B cells than the NFRNS and control groups (P<0.05). After treatment, the FRNS and NFRNS groups had significant reductions in the percentages of total B cells, total memory B cells, IgM+IgD+ memory B cells, IgM+ memory B cells, IgE+ memory B cells, IgD+ memory B cells, and IgG+ memory B cells (P<0.05) and a significant increase in the percentage of class-switched memory B cells (P<0.05). The FRNS group had a significantly higher urinary protein quantification than the NFRNS and control groups (P<0.05) and a significantly lower level of albumin than the control group (P<0.05). In the FRNS group, urinary protein quantification was negatively correlated with the percentage of class-switched memory B cells and was positively correlated with the percentage of IgE+ memory B cells (P<0.05).@*CONCLUSIONS@#Abnormal distribution of memory B cell subsets may be observed in children with FRNS, and the percentages of IgE+ memory B cells and class-switched memory B cells can be used as positive and negative correlation factors for predicting recurrence after GC therapy in these children.

Abstract Introduction Postural instability is considered one of the most disabling symptoms of relapsing-remitting multiple sclerosis (RRMS). Objective To evaluate postural control in patients with RRMS. Method A total of 79 individuals between 18 and 65 years old, of both genders, were distributed into an experimental group composed of patients with RRMS (n = 51) and in a control group composed by healthy individuals (n = 28). The evaluation consisted of anamnesis, Dizziness Handicap Inventory (DHI), visual vertigo analog scale (WAS), and static posturography (Tetrax IBS). Results Patients with RRMS presented mild degree in the DHI and in the VVAS; in Tetrax IBS, they presented higher or lower values of the indices of general stability, weight distribution, synchronization of postural oscillation, fall risk, and frequency bands of postural oscillation in two, five or all eight sensory conditions, in relation to the control group. Vestibular, visual and/or somatosensory dysfunction of peripheral type (51.0%) prevailed over the central type. The RRMS group, with an expanded scale of disability status > 3 points, presented a higher fall risk than with a score ≤ 3 points (p = 0.003). There was a positive correlation of the Fall Risk Index with the total DHI Score (s = 0.380; p = 0.006) and with the VVAS score (s = 0.348; p = 0.012). Conclusion Patients with RRMS may present with inability to maintain postural control due to general instability, desynchronization and increased postural oscillation at frequencies that suggest deficiencies in the vestibular, visual, and somatosensory systems; as well as fall risk related to the state and intensity of functional disability and self-perception of the influence of dizziness on quality of life.

RESUMEN Fundamento: las alternativas terapéuticas en pacientes con esclerosis múltiple no deben centrar sus esfuerzos en la rehabilitación de dominios cognitivos específicos, sino valorar el empleo de estrategias de intervención multimodal, con el propósito de minimizar los factores negativos que intervienen en la salud cognitiva de estos. Objetivo: determinar la efectividad del tratamiento neurorrehabilitador integral en la función cognitiva de los pacientes con esclerosis múltiple remitente recurrente. Métodos: se realizó un estudio cuasiexperimental con dos grupos (un grupo estudio y un grupo control) en pacientes con diagnóstico de esclerosis múltiple remitente recurrente. Cada grupo quedó conformado por 39 pacientes. Los métodos estadísticos exigieron la utilización de un estudio de pruebas repetidas, variante de ANOVA. Para las pruebas de dos momentos se utilizó el concepto de ANOVA de un factor. Resultados: después de la intervención se obtuvo en el grupo de estudio, un aumento de las puntuaciones en las pruebas de velocidad de procesamiento, memoria de trabajo-flexibilidad cognitiva, fluidez verbal y el control inhibitorio; así como disminución en los niveles de fatiga. Se comprobó una mejoría significativa en el estado emocional del grupo de estudio, pues hubo disminución del estado de ansiedad y depresión. Conclusiones: el proceso de neurorrehabilitación integral resultó efectivo al disminuir en los pacientes los niveles de depresión y ansiedad, además de mejorar el funcionamiento cognitivo en el grupo de pacientes que completó el proceso, lo que muestra la viabilidad de un enfoque de neurorrehabilitación integral y su utilidad para mejorar la calidad de vida en adultos con esclerosis múltiple.
ABSTRACT Background: Therapeutic alternatives should not focus their efforts on the rehabilitation of specific cognitive domains, but value the use of multimodal intervention strategies, with the purpose of minimizing the negative factors that intervene in the cognitive health of patients with multiple sclerosis. Objective: to determine the effectiveness of comprehensive neurorehabilitation treatment on the cognitive function of patients with relapsing-remitting multiple sclerosis. Methods: a quasi-experimental study was carried out with two groups (a study group and a control group) in patients diagnosed with relapsing-remitting multiple sclerosis. Each group was made up of 39 patients. Statistical methods required the use of a repeated test study, variant of ANOVA. For the two-moment tests, the one-way ANOVA concept was used. Results: after the intervention, in the study group, an increase in the scores in the tests of processing speed, working memory-cognitive flexibility, verbal fluency and inhibitory control was obtained; as well as decreased levels of fatigue. A significant improvement in the emotional state of the study group was verified, showing a decrease in the state of anxiety and depression. Conclusions: the comprehensive neurorehabilitation process was effective in reducing depression and anxiety levels in patients, in addition to improving cognitive functioning in the group of patients who completed the process, which shows the viability of a comprehensive neurorehabilitation approach and its effectiveness utility to improve quality of life in adults with multiple sclerosis.

ABSTRACT Introduction: The initiation of interferon therapy has been and is the first step in the treatment of many patients with multiple sclerosis, with the aim of delaying the progression of the disease. Objective: To identify the clinical markers of response to treatment with Interferon beta-1a in patients with relapsing-remitting multiple sclerosis. Methods: An observational, descriptive, longitudinal, prospective study was carried out of a series of cases of patients diagnosed with relapsing-remitting multiple sclerosis, who received treatment with interferon beta-1a, in the period between January 2014 and December 2020. All 39 patients were included. Results: The mean age was 34.54 years. The mean disability level at baseline, 12, 24, and 36 months was 1.76; 1.91; 2.1 and 2.37 respectively. The mean number of flares at baseline, 12, 24, and 36 months was 1.13; 0.26; 0.38 and 0.13 respectively. The number of progressions lower by 51% at 36 months is shown. The odds ratio for the absence of relapses is between 2 and 4 times in these patients. Conclusions: Clinical markers of response to treatment with Interferon beta-1a are identified that help assess the response to treatment, which has a positive impact on the evolution of the disease.
RESUMO
ABSTRACT Objective: To describe clinical, diagnostic and therapeutic characteristics of the periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) syndrome. Data source: Literature review in the PubMed database by using specific descriptors to identify all articles published in the English language in the last three years; 38 articles were found. After performing selection of titles and abstract analysis, 13 out of the 38 articles were fully read. Relevant studies found in the references of the reviewed articles were also included. Data synthesis: The PFAPA syndrome (Periodic Fever, Aphthous Stomatitis, Pharyngitis and cervical Adenitis) is a medical condition grouped among the periodic fever syndromes. The etiology is uncertain, but possibly multifactorial, and its symptoms are accompanied by recurrent febrile episodes although weight and height development are preserved. It is a self-limiting disease of benign course with remission of two to three years without significant interference in the patient's overall development. Treatment consists of three pillars: interruption of febrile episodes, increase in the interval between episodes, and remission. Conclusions: Despite several attempts to establish more sensitive and specific criteria, the diagnosis of PFAPA syndrome is still clinical and reached by exclusion, based on the modified Marshall's criteria. The most common pharmacological options for treatment include prednisolone and betamethasone; colchicine may be used as prophylaxis, and surgical treatment with tonsillectomy can be considered in selected cases.
RESUMO Objetivo: Descrever as características clínicas, diagnósticas e de tratamento da síndrome de febre periódica, estomatite aftosa, faringite e adenite (PFAPA). Fontes de dados: Revisão de literatura na base de dados PubMed, feita por meio de descritores específicos para identificar todos os artigos publicados em língua inglesa nos últimos três anos. Dos 38 artigos encontrados, foram encaminhados para leitura integral 13 publicações após seleção de títulos e análise de abstract. Estudos relevantes encontrados nas referências dos artigos revisados também foram incluídos. Síntese dos dados: A PFAPA é traduzida do inglês periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis. Caracterizada por etiologia ainda incerta e possivelmente multifatorial, seus sintomas são acompanhados por episódios recorrentes de febre associados a um desenvolvimento pôndero-estatural preservado. É uma doença autolimitada de curso benigno, com remissão em dois a três anos, sem interferências significativas no desenvolvimento do paciente pediátrico. O tratamento consiste em três pilares: interrupção da crise febril, aumento do intervalo entre crises e remissão. Conclusões: Apesar de várias tentativas de estabelecer critérios atuais mais sensíveis e específicos, o diagnóstico da síndrome PFAPA ainda é clínico e de exclusão com base nos critérios de Marshall modificados. As opções farmacológicas mais utilizadas para o tratamento são a prednisolona e betametasona; colchicina pode ser utilizada como profilaxia e o tratamento cirúrgico com tonsilectomia pode ser considerado em casos selecionados.

ABSTRACT Background: Multiple sclerosis (MS) is a chronic inflammatory disease affecting the central nervous system. The YKL-40 protein, which is secreted from various cells that contribute to inflammation and infection, plays a role in immune regulation. Objective: This study investigated the serum YKL-40 levels of patients with clinically isolated syndrome (CIS) and MS. Methods: The participants was divided into three groups: 1) patients with CIS (n = 20); 2) patients with relapsing-remitting MS (RRMS; n = 39); and 3) healthy individuals (n = 35). The YKL-40 levels in serum samples obtained from the participants were measured using enzyme-linked immunoassays. Results: The median serum YKL-40 level was 20.2 ng/mL (range 9.8-75.9 ng/mL) in the patients with CIS, 22.7 ng/mL (range 13.4-57.9 ng/mL) in the patients with RRMS and 11.0 ng/mL (range 10.0-17.3 ng/mL) in the control group (p < 0.001). The serum YKL-40 levels in the patients with RRMS were correlated with the patients' expanded disability status scale scores and ages (p < 0.05). No relationships were determined between the serum YKL-40 levels and the other variables (p > 0.05). The serum YKL-40 levels were higher in the CIS group than in the MS group. These findings show that the serum YKL-40 levels were high even at the beginning of the disease. The serum YKL-40 levels were also not involved in the progression to clinically definite MS. Conclusions: The findings from this study suggested that YKL-40 may be a useful marker for the inflammatory process of MS.
RESUMO Contexto: A Esclerose Múltipla (EM) é uma doença inflamatória crônica que afeta o sistema nervoso central. A proteína UKL-40, secretada de várias células que participam de processos inflamatórios e infecciosos, desempenha um importante papel na regulação imunológica. Objetivo: Este estudo investigou níveis séricos de YKL-40 em pacientes com Síndrome Clinicamente Isolada (SCI) e EM. Métodos: Os participantes foram divididos em três grupos: 1) pacientes com SCI (n = 20); 2) pacientes com EM recorrente-remitente (EMRR; n = 39); e 3) indivíduos saudáveis (n = 35). Os níveis de YKL-40 em amostras séricas obtidas dos participantes foram medidos usando-se imunoensaios ligados a enzimas. Resultados: O nível sérico médio de YKL-40 foi 20.2 ng/mL (range 9.8-75.9 ng/mL) em pacientes com CIS, 22.7 ng/mL (intervalo entre 13.4-57.9 ng/mL) em pacientes com EMRR e 11.0 ng/mL (intervalo entre 10.0-17.3 ng/mL) no grupo controle (p < 0.001). Os níveis séricos de YKL-40 em pacientes com EMRR estavam correlacionados às pontuações e idades dos pacientes na EDSS (p < 0.05). Não foram determinadas relações entre os níveis séricos de YKL-40 e outras variáveis (p > 0.05). Os níveis séricos de YKL-40 no grupo SCI estavam mais elevados do que no grupo EM. Estes resultados demonstram que os níveis séricos de YKL-40 estavam mais elevados até mesmo no início da doença. Os níveis séricos de YKL-40 também não estavam associados à progressão da EM clinicamente definida. Conclusões: A partir deste estudo, os resultados sugeriram que a proteína YKL-40 pode ser um indicador útil no processo inflamatório da EM.

Relapsing polychondritis (RP) is a rare multisystemic autoimmune disorder characterized by the inflammation and destruction of cartilages, with preference for auricular, nasal and laryngotracheal cartilages. RP may also affect proteoglycan-rich structures, such as, blood vessels, eyes, kidneys, and heart. The central nervous system (CNS) is involved in less than 3% of patients. We report a 32-year-old female with RP associated with a progressive subacute encephalopathy characterized by behavioral disturbances, auditory and visual hallucinations. The EEG showed generalized slow activity and a mononuclear pleocytosis with increased protein was found in the cerebrospinal fluid. The brain magnetic resonance imaging showed multiple supra and infratentorial nodular inflammatory lesions. After initiating treatment with corticosteroids and cyclophosphamide, a significant improvement in chondritis and neurological status was observed.

Objective:To investigate the alterations of cerebellar and cerebral functional connectivity (FC) in patients with relapsing-remitting multiple sclerosis (RRMS) and associations with clinical parameters.Methods:Eighteen acute RRMS patients, 25 remitting RRMS patients and 20 healthy controls (HC) who underwent 3.0 T brain MRI using resting-state functional protocols were collected retrospectively from September 2012 to June 2019 at the First Hospital of Nanchang University. After data preprocessing, the functional connectivity coefficients were calculated between each seed of the cerebellum and every other voxel in the cerebrum for comparison of the inter-groups difference and correlation analysis with clinical variables.Results:Compared with HC, the acute RRMS patients showed significant decreased FC of left cerebellar lobule Ⅵ, the right cerebellar lobule Ⅵ and the left vermis ( P<0.001, Gaussian Random Field theory correction at cluster level P<0.05), the remitting RRMS patients showed the decreased FC of the right cerebellar Crus I, the left cerebellar Crus Ⅰ, the left cerebellar lobule Ⅴ and right cerebellar lobule Ⅴ ( P<0.001, Gaussian Random Field theory correction at cluster level P<0.05). In the acute RRMS patients, FC between the left cerebellar lobule Ⅵ and the right precentral/postcentral gyrus was negatively correlated with illness duration ( r=-0.492, P=0.038). FC between the right cerebellar lobule Ⅵ and the right postcentral gyrus/right superior parietal gyrus was negatively correlated with the expanded disability status scale scores ( r=-0.611, P=0.007). FC between the left vermis and the left calcarine gyrus was negatively correlated with illness duration ( r=-0.534, P=0.02). In the remitting RRMS patients, FC between the right Crus Ⅰ and the left anterior insula was negatively correlated with normalized total white matter lesion load ( r=-0.453, P=0.023). FC between the right Crus Ⅰ and the right anterior insula was negatively correlated with modified fatigue impact scale ( r=-0.450, P=0.024). Conclusions:The cerebello-cerebral connection of cognitive related networks is decreased in both acute attack and remission stages of RRMS patients. In addition, the cerebello-cerebral connection in sensorimotor network can also be significantly impacted in acute attack stage, while the cerebello-cerebral connection of emotional network may be decreased in remission stage.
RESUMO
Objective:To investigate the clinical efficacy and safety of bendamustine combination regimen in the treatment of patients with relapsed or refractory multiple myeloma (RRMM).Methods:From March 2020 to December 2020, 16 patients with RRMM were treated with bendamustine combination regimen in Beijing Jishuitan Hospital. The efficacy and adverse events (AEs) of bendamustine combination regimen were retrospectively analyzed in the 16 patients.Results:The median treatment lines for 16 patients with RRMM who received bendamustine combination regimen was 4 lines, and the median course of treatment was 3 (1-8). The median follow-up time after bendamustine treatment started was 5.3(1.3-9.2)months. Among the 16 cases, the disease control rate (DCR), overall response rate(ORR), and ≥ very good partial remission (VGPR) rate were 13/16, 5/16, 4/16 respectively. The median PFS was 4.9 months. Among them, the ORR of bendamustine combined with immunomodulators was higher. AEs were anemia, leukopenia, neutropenia, thrombocytopenia and fatigue. No patients who stopped treatment and adjusted the dose due to AEs.Conclusions:Bendamustine combination regimen is an effective and safe regimen for relapsed/refractory multiple myeloma.
RESUMO
Objetivo: Avaliar o impacto orçamentário da inclusão da cladribina oral no tratamento de esclerose múltipla remitente-recorrente em alta atividade da doença (EMRR HDA) no Sistema de Saúde Suplementar (SSS). Métodos: Foi conduzida uma análise de impacto orçamentário, sob a perspectiva do SSS, com horizonte temporal de quatro anos, considerando a abordagem de coorte aberta na qual o número de pacientes elegíveis para tratamento varia em cada ano com a introdução de novos pacientes diagnosticados de EMRR HDA e a retirada de indivíduos prevalentes devido a morte ou progressão secundária. Foram considerados custos médicos diretos, incluindo a aquisição e administração de medicamentos, monitoramento, eventos adversos e surtos. Os comparadores utilizados na análise foram: alentuzumabe, fingolimode, natalizumabe e ocrelizumabe. Os custos foram apresentados em real brasileiro (BRL). Resultados: O custo incremental da inclusão da cladribina oral para o SSS foi estimado em 463.265 BRL, 739.691 BRL, -1.414.963 BRL, -3.719.007 BRL, nos anos 1, 2, 3 e 4, respectivamente. Isso resultou em um custo incremental total de -3.931.015 BRL no período analisado, representando 1,5% da redução orçamentária total no tratamento de EMRR HDA. Conclusão: A inclusão da cladribina oral para o tratamento de pacientes com diagnóstico de EMRR HDA poderia gerar uma economia substancial para o sistema brasileiro de saúde suplementar, atingindo um valor de cerca de 3,9 milhões de BRL em um período de quatro anos
Objective: To evaluate the budget impact of adopting cladribine tablets as a treatment strategy for relapsing remitting multiple sclerosis with high disease activity (RRMS HDA), from the Brazilian private healthcare system perspective. Methods: A budget impact analysis, under private healthcare system perspective, with a 4-years time horizon was conducted, considering the open cohort approach in which the number of patients eligible for treatment varies each year with the introduction of newly diagnosed RRMS HDA patients and the drop out of prevalent individuals due to death or secondary progression. Direct medical costs, including acquisition, drug administration, monitoring, adverse events and relapses were considered. Comparators used in the analysis were: alentuzumab, fingolimod, natalizumab and ocrelizumab. Costs were presented in Brazilian real (BRL). Results: The incremental cost of incorporating cladribine tablets into the private healthcare system was estimated at 463,265BRL, 739,961BRL, -1,414,963 BRL, -3,716,007 BRL, in years 1, 2, 3 and 4, respectively. This resulted in a total incremental cost of -3,931,015 BRL over the period analyzed, representing 1.5% of the total budget reduction in the treatment of RRMS HDA. Conclusion: Incorporation of cladribine tablets for the management of RRMS HDA could generate substantial savings for the private healthcare system, reaching a value of approximately 3.9 million BRL in a 4-years period

El diagnóstico, evaluación y tratamiento del síndrome nefrótico en el niño data de los tiempos de Hipócrates. Sin embargo, en la actualidad algunos pacientes con la enfermedad siguen siendo un reto terapéutico para el médico. Nos proponemos examinar en la literatura reciente, distintas propuestas o protocolos de tratamiento y las nuevas drogas que pueden utilizarse en la atención al paciente con esta enfermedad. Los protocolos de tratamiento varían con relativa frecuencia y las drogas, tanto en los síndromes nefróticos recaedores frecuentes, corticodependientes o corticorresistentes, no garantizan en muchas ocasiones la curación del paciente. Cuando fracasan los esteroides se pueden utilizar agentes alquilantes, inhibidores de la calcineurina, antiproliferativos, anticuerpos monoclonales y otros fármacos, pero existen pacientes que no tienen remisión de la proteinuria con ninguno de estos tratamientos. Por sus características evolutivas, algunos pacientes con síndrome nefrótico idiopático siguen siendo un reto para el médico que trata de evitar su evolución hacia la pérdida de la función renal. A pesar de todos los avances en la atención del niño con síndrome nefrótico, desde el descubrimiento de los esteroides, antibióticos, diuréticos e inmunosupresores, en la actualidad no sabemos exactamente cuál es el mejor tratamiento en las formas resistentes del síndrome nefrótico idiopático en niños(AU)
Diagnosis, evaluation and treatment of nephrotic syndrome in children dates from Hypocrate times. However, nowadays some patients with this disease are still a therapeutic challenge for physicians. The aim of this work is to search in recent literature different proposals or treatment protocols, and new drugs that can be used in the care of patients with this disease. Treatment protocols vary with relative frequency and drugs, as well as in frequent relapsing nephrotic, corticodependent or corticoresistant syndromes, do not guarantee in many ocassions the cure of the patient. When steroids fail, alkylanting agents, calcineurin depressants, antispreading, monoclonal antibodies and other drugs can be ussed; but there are patients who do not have remission of proteinuria with any of these treatments. Due to their evolutive characteristics, some patients with idiopathic nephrotic syndrome are still a challenge for the physicians who try to avoid its evolution toward the loss of renal function. Although all the advances in the care of children with nephrotic syndrome due to the discover of steroids, antibiotics, diuretics and immunosupressive drugs, nowadays we do not exactly know which is the best treatment for the resistant types of idiopathic nephrotic syndrome in children(AU)
