Estado actual y retos futuros en el tratamiento de las enfermedades reumáticas / Current status and future challenges in the treatment of rheumatic diseases

Las nuevas estrategias, que incluyen el diagnóstico y el tratamiento tempranos, el enfoque de tratamiento dirigido a un objetivo, la remisión como ese objetivo principal del tratamiento, la participación de los pacientes en las decisiones terapéuticas, junto con el desarrollo de nuevos tratamientos efectivos, han cambiado las expectativas de los reumatólogos y de los pacientes con enfermedades reumáticas. Todavía existen, sin embargo, importantes desafíos tales como la seguridad a largo plazo de los tratamientos actuales y poder escoger tratamientos más individualizados y eficaces, de forma tal de elegir el mejor tratamiento para cada paciente. El futuro, como en el resto de la medicina, probablemente sea la prevención del desarrollo de enfermedades reumáticas. Discutiremos estos temas en esta revisión. (AU)

New strategies, including early diagnosis and treatment, targeted therapy, remission as the main objective of treatment, patient involvement in therapeutic decision-making, and the development of new effective therapies, have changed the expectations of rheumatologists and patients with rheumatic diseases.There are still serious challenges, such as the long-term safety of current treatments and the ability to make more individualized and effective treatments to choose the best treatment for each patient. The future, as that of the whole of medical science, will probably lie in preventing the development of rheumatic diseases. We will discuss these issues in this review. (AU)

Combinación de antidepresivos vs. aumentación con antipsicóticos atípicos tras no lograr la remisión en la depresión unipolar / Combination of antidepressants vs. augmentation with atypical antipsychotics upon failure to achieve remission in unipolar depression

RESUMEN: Introducción: Lograr la recuperación funcional lo más rápido posible en el tratamiento de la depresión unipolar es un reto que la práctica clínica debe tratar de afrontar en la actualidad, ya que cualquier retraso en lograr la remisión de los síntomas es predictivo de un mayor número de recurrencias y mayores tasas de morbimortalidad. En esta revisión comprensiva, nuestro objetivo es guiar a los clínicos en su elección de aumentar con antipsicóticos atípicos o combinar el fármaco de referencia con un segundo antidepresivo, después de que se haya optimizado la dosis del antidepresivo seleccionado inicialmente y/o se haya cambiado el antidepresivo, sin lograr remisión, o bien cuando solo han obtenido una respuesta parcial después de un tiempo suficiente a una dosis apropiada. Estas decisiones surgen con frecuencia en la práctica clínica diaria. Metodología: Se realizó una búsqueda sistemática en PubMed bajo varias combinaciones clave de palabras, resultando en 230 informes. Después de aplicar los criterios de inclusión y según el título y el resumen, el número final de informes seleccionados para la revisión completa fue de 113. Se respondieron dos preguntas principales con base en estos estudios: 1) ¿Existe evidencia para recomendar claramente la combinación de antidepresivos versus potenciación con antipsicóticos (y el momento correcto para hacerlo) en la depresión unipolar no respondedora, una vez que las estrategias de optimización o de cambio han fallado en obtener la remisión? y 2) ¿Es posible identificar algunas características clínicas para guiar la decisión de combinación de antidepresivos versus potenciación con agentes antipsicóticos? Resultados: Según nuestro análisis, no hay datos disponibles para seleccionar una estrategia de otra de manera clara. Sin embargo, sugerimos favorecer una combinación o estrategia de aumento, basada en un enfoque de "tratamiento contra objetivos dianas" para perfilar al paciente, considerando una o dos características clínicas predominantes que permanecen activas como parte de una depresión mayor con respuesta parcial. Un adecuado análisis de los dominios sintomáticos presentes, una visión crítica de las guías clínicas actuales y de las opciones preferidas, considerar la bipolaridad oculta como uno de los principales diagnósticos diferenciales y adoptar una actitud enérgica pero lúcida en esta etapa del tratamiento son, a nuestro juicio, fundamentales para lograr recuperación ad integrum del paciente.

ABSTRACT Introduction: achieving functional recovery as quickly as possible in the treatment of unipolar depression is a challenge that clinical practice must try to meet nowadays, since any delay in accomplishing remission of the symptoms is predictive of a larger number of recurrences and higher morbidity and mortality rates. In this topical review we aim to guide clinicians in their choice to augment with atypical antipsychotics or to combine the baseline drug with a second antidepressant, after the dose of the antidepressant initially selected has been optimized and/or the antidepressant has been changed, not achieving remission, or resulting only in a partial response after sufficient time at an appropriate dose. These decisions arise frequently in everyday clinical practice. Methodology: a systematic search in PubMed was performed under several key combinations of words, resulting in 230 reports. After applying inclusion criteria and based in title and abstract, the final number of reports selected for full revision were 113. Two main questions were answered based on these studies: 1) Is there evidence to clearly recommend combination of antidepressants vs. augmentation with antipsychotics (and the correct moment to do it) in non-responsive unipolar depression, once optimization or switching strategies have failed to obtain remission? and 2) Is it possible to identify some clinical features to guide the decision of combination of antidepressants vs. augmentation with antipsychotic agents? Results: According to our analysis, there is no data available to select one strategy from another in a clear-cut manner. Nevertheless, we suggest favoring a combination or augmentation strategy, based in a "treating to target" approach to profile the patient, considering one or two predominant clinical features that remain active as part of a major depression with partial response. Proper analysis of the symptomatic domains present, a critical view of current clinical guidelines and preferred options, considering hidden bipolarity as one of the main differential diagnoses and adopting an energetic but lucid attitude at this stage of treatment are, in our view, fundamental for achieving ad integrum patient recovery.

Comparison between DAS28-ESR and DAS28- CRPus for patients with rheumatoid arthritis: application in a population of southern Brazil

Abstract The Disease Activity Score 28 (DAS28) shows discrepancies when using erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) scores to assess rheumatoid arthritis (RA). This study aimed to verify the agreement between the DAS28-CRP and DAS28-ESR scores in patients with RA from the south of Brazil. A unicentric cross-sectional study was performed (n = 56). The diagnosis of the patients followed the American College of Rheumatology/ European League Against Rheumatism criteria, and their DAS28 were calculated. The DAS28- ESR score was higher than the DAS28-CRP (DAS28-ESR mean 4.8±1.6; DAS28-CRP mean 4.3±1.4) for 83.9% of the patients. The DAS28-CRP and DAS28-ESR scores showed a very strong correlation (Pearson's coefficient = 0.922; P<0.0001, 95% CI +0.87 to +0.95, statistical power 100%). Spearman's correlation coefficient (0.49; P=0.0001, 95% CI +0.25 to +0.67, statistical power 47.54%) showed a moderate correlation between the unique components of the DAS28 formulas. There was agreement between the tests in only 36 of the patients (64.29%). Among the discordant categories, DAS28-ESR overestimated the classification in 16 patients (28.5%). The Kappa coefficient between the categories was 0.465 (SE 0.084, 95% CI +0.301 to +0.630), showing a moderate degree of agreement between the instruments. Although the DAS28-ESR and DAS28-CRP were highly correlated, they differed significantly in terms of patient categorization and should not be used interchangeably

Incorporación de las altas dosis de antraciclina en el tratamiento de la leucemia mieloide aguda del adulto / Incorporation of the high dose of anthracycline in the treatment of adult acute myeloid leukemia

Introducción: La leucemia mieloide aguda representa el 80 por ciento de las leucemias agudas entre los adultos; el tratamiento de inducción a la remisión, para los pacientes menores de 60 años, está basado en la combinación de antraciclinas y arabinósido de citosina. Objetivo: incorporar las altas dosis de antraciclinas al tratamiento de inducción de la leucemia mieloide aguda no promielocítica en pacientes adultos menores de 60 años. Método: Se realizó un estudio cuasiexperimental en 41 pacientes con este diagnóstico, atendidos en el servicio de Adultos del Instituto de Hematología e Inmunología, desde septiembre del 2013 hasta diciembre del 2016. A todos los pacientes se les realizó estudios morfológicos, inmunológicos, citogenéticos y moleculares al inicio de la enfermedad y ecocardiografía para determinar la fracción de eyección y de acortamiento del ventrículo izquierdo al año de finalizado el tratamiento, para determinar la cardiotoxicidad por el uso de las altas dosis de antraciclinas. Resultados: La distribución por edad fue mayor en el grupo de 46 a 52 años representado por el 26,8 por ciento de los casos y predominó el sexo masculino 60,9 por ciento. En el 85 por ciento de los casos la enfermedad apareció de novo. Según los criterios morfológicos de la clasificación Franco Británico Americana el 31,7 por ciento correspondió a la variante M1, en estrecha relación con las determinaciones por citometría de flujo, para esta variedad. Los genes más comúnmente involucrados fueron el NPM1 y el AML/ETO, para el 24 por ciento y 22 por ciento, respectivamente. El 56,1 por ciento de los pacientes alcanzó la remisión hematológica con un solo ciclo de tratamiento y el 14,6 por ciento, necesitó realizar un segundo esquema de inducción. No se reportaron eventos de cardiotoxocidad por antraciclina durante el tratamiento, ni al año de culminado este. Conclusiones: Con el uso de las altas dosis de antraciclina se lograron remisiones hematológicas, sin toxicidad cardiovascular demostrada(AU)

Introduction: Acute myeloid leukemia represents 80 percent of acute leukemias among adults; the induction treatment to obtain remission in patients under 60 years old is based on the combination of anthracyclines and cytosine arabinoside. Objective: to incorporate the high doses of anthracyclines to the treatment of induction of non-promyelocytic acute myeloid leukemia in adult patients under 60 years of age. Method: We conducted a quasi-experimental study in 41 patients with this diagnosis, at the adult clinic service of the Institute of Hematology and Immunology, from september 2013 to december 2016. Morphological, immunological, cytogenetic and molecular studies were carried out at the beginning of the disease and also echocardiography was performed to determine the ejection fraction and shortening of the left ventricle a year after the end of treatment, to determine cardiotoxicity due to the use of high doses of anthracyclines. Results: The distribution by age was higher in the group of 46 to 52 years represented by 26.8 percent of the cases and the male sex predominated 60.9 percent. In 85 percent of the cases the disease appeared de novo. According to the morphological criteria of the French American British classification, 31.7 percent corresponded to the M1 variant, in close relation with the determinations by flow cytometry, for this variety. The genes most commonly involved were NPM1 and AML / ETO, for 24 percent and 22 percent respectively. 56.1 percent of patients achieved hematological remission with a single treatment cycle and 14.6 percent of patients needed a second induction scheme. No anthracycline cardiotoxicity events were reported during the treatment, nor a year after the treatment, in the patients evaluated. Conclusions: With the use of high doses of anthracycline, have been hematological remissions, without demonstrated cardiovascular toxicity(AU)

Histological remission of autoimmune hepatitis after the addition of allopurinol and azathioprine dose reduction

The standard therapy for some autoimmune diseases consists of a combination of corticosteroids and thiopurines. In non-responders to thiopurine drugs, the measurement of the metabolites of azathioprine, 6-thioguanine, and 6-methylmercaptopurine, can be a useful tool. The measurement has been used during the treatment of inflammatory bowel diseases and, less commonly, in autoimmune hepatitis. Many patients preferentially metabolize thiopurines to 6-methylmercaptopurine (6-MMP), which is potentially hepatotoxic, instead of 6-thioguanine, the active immunosuppressive metabolite. The addition of allopurinol shifts the metabolism of thiopurine towards 6-thioguanine, improving the immunosuppressive effect. We present the case of a 51-year-old female with autoimmune hepatitis who had a biochemical response after azathioprine and prednisone treatment without histological remission, and who preferentially shunted to 6-MMP. After the addition of allopurinol, the patient's 6-thioguanine levels increased, and she reached histological remission with a reduction of 67% of the original dose of azathioprine. The patient did not develop clinical manifestations as a consequence of her increased immunosuppressive state. We also review the relevant literature related to this issue. In conclusion, the addition of allopurinol to thiopurine seems to be an option for those patients who do not reach histological remission and who have a skewed thiopurine metabolite profile.

Outcomes of inpatients with severe mental illness: a naturalistic descriptive study

Objective: To describe and evaluate the response and predictors of remission during inpatient treatment in a psychiatric unit in a general hospital based on symptomatology, functionality, and quality of life (QoL). Methods: Patients were admitted to a psychiatric unit in a tertiary general hospital in Brazil from June 2011 to December 2013 and included in the study if they met two of the severe mental illness (SMI) criteria: Global Assessment of Functioning (GAF) ≤ 50 and duration of service contact ≥ 2 years. Patients were assessed by the Brief Psychiatric Rating Scale (BPRS), the Clinical Global Impression (CGI) Severity Scale , GAF, the World Health Organization Quality of Life Instrument – Abbreviated version (WHOQOL-Bref), and specific diagnostic scales. Results: A total of 239 patients were included. BPRS mean scores were 25.54±11.37 at admission and 10.96±8.11 at discharge (p < 0.001). Patients with manic episodes (odds ratio: 4.03; 95% confidence interval: 1.14-14.30; p = 0.03) were more likely to achieve remission (CGI ≤ 2 at discharge) than those with depressive episodes. Mean length of stay was 28.95±19.86 days. All QoL domains improved significantly in the whole sample. Conclusion: SMI patients had marked improvements in symptomatic and functional measures during psychiatric hospitalization. Patients with manic episodes had higher chance of remission according to the CGI.

Efficacy of Adalimumab in Korean Patients with Crohn's Disease

BACKGROUND/AIMS: Adalimumab is effective for both remission induction and the maintenance of Crohn's disease (CD) in Western countries. We evaluated the efficacy of adalim-umab in the conventional step-up treatment approach for CD in Korea. METHODS: We retrospectively reviewed 62 patients with CD who were treated with adalimumab. Their Crohn's disease activity index (CDAI) was measured at weeks 4, 8, and 52. Clinical remission was defined as a CDAI score <150. Induction and maintenance outcomes were analyzed. RESULTS: Forty-one patients (66.1%) achieved a reduction of 70 CDAI points at week 8. Among them, 28 (45.2%) achieved clinical remission at week 8, 20 (32.3%) maintained remission at week 52. The absence of prior anti-tumor necrosis factor (TNF) therapy and Montreal classification L1 at baseline predicted clinical remission at week 8 in the multivariate logistic regression analysis. In the Cox proportional hazards model, the hazard ratio for the secondary loss of response during maintenance therapy after clinical remission induction was significantly higher in patients who showed initial mild CDAI severity or Montreal classification A3. CONCLUSIONS: In our study, anti-TNF therapy-naive and Montreal classification L1 were associated with adalimumab efficacy as induction therapy in CD. Further studies are warranted to determine the prognostic factors for the long-term response after adalimumab therapy.

Efficacy and Safety of Adalimumab in Moderately to Severely Active Cases of Ulcerative Colitis: A Meta-Analysis of Published Placebo-Controlled Trials

BACKGROUND/AIMS: To evaluate the efficacy and safety of adalimumab (ADA) in moderately to severely active ulcerative colitis (UC) patients who are unresponsive to traditional therapy. METHODS: Electronic databases, including the PubMed, Embase, and Cochrane databases, were searched to April 20, 2014. UC-related randomized controlled trials (RCTs) that compared ADA with placebo were eligible. Review Manager 5.1 was used for data analysis. RESULTS: This meta-analysis included three RCTs. ADA was considerably more effective compared with a placebo, and it increased the ratio of patients with clinical remission, clinical responses, mucosal healing and inflammatory bowel disease questionnaire responses in the induction and maintenance phases (p<0.05), as well as patients with steroid-free remission (p<0.05) during the maintenance phase. Clinical remission was achieved in a greater number of UC cases in the ADA 160/80/40 mg groups (0/2/4 week, every other week) compared with the placebo group at week 8 (p=0.006) and week 52 (p=0.0002), whereas the week 8 clinical remission rate was equivalent between the ADA 80/40 mg groups and the placebo group. Among the patients who received immunomodulators (IMM) at baseline, ADA was superior to the placebo in terms of inducing clinical remission (p=0.01). Between-group differences were not observed in terms of serious adverse events (p=0.61). CONCLUSIONS: ADA, particularly at doses of 160/80/40 mg (0/2/4 week, every other week), is effective and safe in patients with moderate-to-severe UC who are unresponsive to traditional treatment. Concomitant IMM therapy may improve the short-term therapeutic efficacy of ADA.

Fotoféresis en el tratamiento de Síndrome de Sézary: Caso clínico / Sézary syndrome treated with extracorporeal photopheresis: Report of one case

Sézary syndrome (SS) is an unusually aggressive T- cell lymphoma characterized by the triad of erythroderma, the presence of more than 1,000 Sézary cells in peripheral blood and lymphadenopathies. It is accompanied by generalized pruritus and poor quality of life. The management of SS depends on its stage, patient comorbidities, and treatment availability. Extracorporeal photopheresis (ECP) is the first line of treatment for patients with T-cell lymphomas in stage IVA1, IVA2 or SS. This treatment comprises three phases: leukapheresis, photoactivation and subsequent reinfusion of lymphocytes. As it is an immunomodulatory therapy it does not produce generalized immunosuppression. We report a 76 year-old male with SS stage IIIb initially treated with 12 sessions of ultraviolet phototherapy without response. After 10 well-tolerated sessions of ECP, itching and skin lesions eventually disappeared.

Salvaged single-unit cord blood transplantation for 26 patients with hematologic malignancies not in remission

Treatments for patients with hematologic malignancies not in remission are limited, but a few clinical studies have investigated the effects of salvaged unrelated cord blood transplantation (CBT). We retrospectively studied 19 patients with acute leukemia, 5 with myelodysplastic syndrome (MDS with refractory anemia with excess blasts [RAEB]), and 2 with non-Hodgkin's lymphoma who received 1 CBT unit ≤2 loci human leukocyte antigen (HLA)-mismatched after undergoing myeloablative conditioning regimens between July 2005 and July 2014. All of them were in non-remission before transplantation. The infused total nucleated cell (TNC) dose was 4.07 (range 2.76-6.02)×107/kg and that of CD34+ stem cells was 2.08 (range 0.99-8.65)×105/kg. All patients were engrafted with neutrophils that exceeded 0.5×109/L on median day +17 (range 14-37 days) and had platelet counts of >20×109/L on median day +35 (range 17-70 days). Sixteen patients (61.5%) experienced pre-engraftment syndrome (PES), and six (23.1%) patients progressed to acute graft-versus-host disease (GVHD). The cumulative incidence rates of II-IV acute GVHD and chronic GVHD were 50% and 26.9%, respectively. After a median follow-up of 27 months (range 5-74), 14 patients survived and 3 relapsed. The estimated 2-year overall survival (OS), disease-free survival (DFS), and non-relapse mortality (NRM) rates were 50.5%, 40.3%, and 35.2%, respectively. Salvaged CBT might be a promising modality for treating hematologic malignancies, even in patients with a high leukemia burden.

Timing in resolution of left heart dilation according to the degree of mitral regurgitation in children with ventricular septal defect after surgical closure / Momento da resolução da dilatação do coração esquerdo segundo o grau de regurgitação mitral em crianças submetidas a fechamento cirúrgico de defeito do septo ventricular

OBJECTIVE: Children with ventricular septal defects (VSD) can have chronic volume overload, which can result in changes of left heart echocardiographic parameters. To evaluate the changes before and after surgical closure, the children were divided into three groups according to the degree of mitral regurgitation (MR), and their echocardiographic characteristics were reviewed at serial follow-up after surgical closure. METHODS: The preoperative, and one-, three-, and 12-month postoperative echocardiographic data of 40 children who underwent surgical closure of VSD were retrospectively reviewed. Left ventricular end-diastolic volume (LVEDV), left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic dimension (LVESD), mitral valvular characteristics, including degree of MR and mitral valve annulus, and left atrial (LA) characteristics, including volume and dimensions, were observed. RESULTS: Preoperative LVEDV, LVEDD, LVESD, mitral valvular annulus, LA volume, and LA dimensions were significantly larger in children with MR. Additionally, there were significant decreases in LVEDV, LVEDD, LA volume, and LA dimensions at one, three, and 12 months postoperatively. The degree of MR also improved to a lower grade after surgical closure of the VSD without additional mitral valve repair. CONCLUSION: The echocardiographic parameters of left heart dilation and MR in children with VSD improved within the first year after surgical closure without additional mitral valve repair. Furthermore, in all of the patients with VSD, regardless of MR, LA dilation was reduced within three months after surgical closure of the VSD; however, LV and mitral valve annular dilatation decreased within 12 months. .

OBJETIVO: Crianças com defeito do septo ventricular (DSV) podem apresentar sobrecarga devolume crônica, que pode resultar em mudanças nos parâmetros ecocardiográficos do curacao esquerdo. Para avaliar as mudanças antes e depois do fechamento cirúrgico, as crianças foram divididas em 3 grupos segundo o grau de regurgitação mitral (RM) e suas características eco-cardiográficas foram analisadas com acompanhamento em série após o fechamento cirúrgico. MÉTODO: Revisamos retrospectivamente os dados ecocardiográficos de 40 crianças submetidas afechamento cirúrgico de DSV antes da cirurgia e nos meses 1, 3 e 12 após a cirurgia. Observamos o volume diastólico final do ventrículo esquerdo (VDFVE), dimensão diastólica final do ventrículo esquerdo (DDFVE) e dimensão sistólica final do ventrículo esquerdo (DSFVE), características da válvula mitral, incluindo grau de RM e o anel da válvula mitral, e características do átrio esquerdo (AE), incluindo volume e dimensões. RESULTADOS: Os resultados para VDFVE, DDFVE, DSFVE, anel da válvula mitral, volume do AE e dimensões do AE foram significativamente maiores em crianças com RM. Além disso, não houveredução significativa no VDFVE, DDFVE, volume do AE e nas dimensões do AE nos meses 1, 3e 12 após a cirurgia. O grau de RM também apresentou melhoria para um grau menor após o fechamento cirúrgico do DSV sem reparo adicional da válvula mitral. CONCLUSÃO: Os parâmetros ecocardiográficos de dilatação do coração esquerdo e a RM em crianças com DSV haviam apresentado melhora no primeiro ano após o fechamento cirúrgicos em reparo adicional da válvula mitral. Além disso, em todos os pacientes com DSV, independentemente ...

Remisión completa de síndrome nefrótico asociado a carcinoma cervicouterino luego de tratamiento del tumor: Comunicación de 2 casos / Complete remission of nephrotic syndrome associated with carcinoma of the cervix after treatment of the tumor: Report of two cases

Nephrotic syndrome secondary to paraneoplastic glomerulopathies is exceptional. We are aware of only three cases reported of cervical carcinomas associated with nephrotic syndrome. Two women, aged 40 and 79 years, presented with nephrotic syndrome. The first had a membranous nephropathy and the second was not biopsied. The first women had a metrorrhagia after 8 months of unsuccessful therapy with corticosteroids and immunosuppressive drugs. An advanced cervical carcinoma with lymph node metastases was found. In the second patient, a cervical carcinoma and hematometra was discovered two months after diagnosis ofa nephrotic syndrome. The syndrome subsided completely, nine months after radiotherapy and chemotherapy in the first patient and 10 months after hysterectomy in the second patient.

Synchronous pyoderma gangrenosum and inflammatory bowel disease, healing after total proctocolectomy / Pioderma gangrenoso associado a doença inflamatória intestinal, com resolução após proctocolectomia total

We present a female patient observed with painful violaceous plaques with central bullae and pustules on the lower limbs, rapidly transformed into ulcers, associated with bloody diarrhea, recurrent oral erosions and hyperthermia in the previous 3 months. Cutaneous biopsy was consistent with pyoderma gangrenosum, and intestinal diagnostic procedures revealed a non-classifiable inflammatory bowel disease with high x-ANCA titers. Soon after admission the patient was submitted to total proctocolectomy following colonic perforation. Complete ulcer healing occurred three months after surgery, without recurrence. Pyoderma gangrenosum is a rare dermatosis frequently associated with inflammatory bowel disease. This case is particularly interesting for the synchronic clinical presentation of cutaneous and intestinal diseases, but also for the prompt regression of the former after total proctocolectomy.

Apresentamos uma paciente do sexo feminino observada com múltiplas placas violáceas dolorosas dos membros inferiores, com bolhas e pústulas evoluindo rapidamente para lesões ulceradas, surgindo no contexto de diarreia sanguinolenta, erosões orais recorrentes e febre com três meses de evolução. A biópsia cutânea foi compatível com pioderma gangrenoso; o estudo complementar revelou doença inflamatória intestinal inclassificável com títulos elevados de x-ANCA. Após perfuração cólica, a doente foi submetida a proctocolectomia total, com rápida cicatrização das lesões cutâneas ulceradas em três meses, sem recorrência. O pioderma gangrenoso é uma dermatose rara frequentemente associada a doença inflamatória intestinal. É interessante verificar neste caso a apresentação clínica sincrónica das doenças cutânea e intestinal, bem como a rápida resolução da primeira após proctocolectomia total.

Tratamiento de la leucemia linfoide aguda del adulto: Experiencia de un hospital en la Ciudad de México / Results of treatment of acute lymphoblastic leukemia in two cohorts of Mexican patients

Background: GIMEMA ALL 0288 trial was designed to evaluate the impact of a 7-day prednisone (PDN) pretreatment on complete remission of acute lymphoblastic leukemia. We adopted this trial in 2007. Aim: To evaluate the results of treatment in two cohorts of patients with acute lymphoblastic leukemia, treated from 2007 to January 2009 and from February to December 2009. Material and Methods: We studied 99 patients treated in the first period (58 males) and 54 patients treated in the second period (33 males) The age of patients ranged from 16 to 60 years and 70 percent of patients were of high risk. BCR/ABL fusion transcript was present in 12 percent of patients. Results: Remission rates were 61 and 51 percent for patients of the first and second group of treatment, respectively. The main cause of death were infections during the induction period. There were 49 relapses, mainly detected in the blood marrow. Global and event free 34 months survival were 32 and 30 percent respectively. Multivariate analysis disclosed risk stratification and central nervous system infiltration as risk factors for mortality. Conclusions: The main obstacles for the treatment of acute lymphoblastic leukemia in these cohorts of patients were the high incidence of infections and the lack of use of growth stimulating factors.

Vitiligo y terapia con inmunoglobulina intravenosa: a propósito de un paciente con síndrome de Sjögren / Remission of vitiligo during treatment with intravenous immunoglobulin: Report of one case

Vitiligo is associated with other autoimmune diseases. We report a 52-year-old male with a Sjögren syndrome that was treated with monthly pulses of intravenous immunoglobulin for a chronicinflammatory demyelinating polyradiculoneuropathy. The neurological disorder responded adequately to the treatment and the patient also noted a marked remission of his vitiligo with almost compete re-pigmentation of the scalp and face and partial repigmentation of other areas.

Efecto de una sola dosis de ácido zoledrónico en un caso de enfermedad de Paget ósea / Effect of a single dose of zoledronic acid in a case of Paget bone disease

La enfermedad de Paget es un trastorno crónico del remodelado óseo, caracterizado por un aumento de la resorción ósea producido por osteoclastos atípicos, seguido por un incremento acelerado de la formación ósea, lo que resulta en la formación de hueso en mosaico desorganizado. Un excelente marcador bioquímico para orientar el diagnóstico y seguimiento es la fosfatasa alcalina (FAL). Se presenta el caso de un paciente de 90 años, de sexo masculino, con diagnóstico de enfermedad de Paget. Se inicia tratamiento con pamidronato vía oral con respuesta parcial, por lo que se rota a pamidronato endovenoso. Disminuyen el dolor y la concentración plasmática de FAL, persistiendo con centellograma óseo patológico. Luego de varios años de tratamiento, con adecuado aporte de calcio y vitamina D, comienza nuevamente con dolor y valores elevados de FAL. Se decide iniciar tratamiento con ácido zoledrónico endovenoso 4 mg, única aplicación, obteniéndose remisión clínica y bioquímica desde hace cuatro años y mejoría de la imagen centellográfica. Este informe refiere la buena respuesta, sostenida en el tiempo, al tratamiento con única dosis de ácido zoledrónico en un paciente que presentó resistencia al pamidronato.

Paget's disease is a chronic disorder of bone remodeling characterized by increase of bone resorption by atypical osteoclasts, followed by rapid increase in bone formation resulting in a disorganized mosaic bone. The biochemical marker for early diagnosis and monitoring is serum alkaline phosphatase (ALP). We report the case of a 90 year old male, with diagnose of Paget's disease. Pamidronate treatment was started orally with partial response, so it was switched to intravenous pamidronate. Pain intensity and FAL levels diminished. The scyntigraphic scan, however, though improved, persisted abnormal. After several years of treatment, with adequate calcium and vitamin D support, the patient presents pain and increase of FAL. We administered intravenous zoledronic acid (4 mg) in a single dose. After this treatment we observed clinical and biochemical remission during four years and a significantly improvement in the scintigraphy. We report a case of Paget´s disease, resistant to pamidronate treatment in whom a single dose of zoledronic acid produced clinical and biochemical remission during 4 years and a significant improvement in the scintigraphic scan.

Anti-hypertensive drugs have different effects on ventricular hypertrophy regression: [review]

OBJECTIVES: There is a direct relationship between the regression of left ventricular hypertrophy (LVH) and a decreased risk of mortality. This investigation aimed to describe the effects of anti-hypertensive drugs on cardiac hypertrophy through a meta-analysis of the literature. METHODS: The Medline (via PubMed), Lilacs and Scielo databases were searched using the subject keywords cardiac hypertrophy, antihypertensive and mortality. We aimed to analyze the effect of anti-hypertensive drugs on ventricle hypertrophy. RESULTS: The main drugs we described were enalapril, verapamil, nifedipine, indapamina, losartan, angiotensin-converting enzyme inhibitors and atenolol. These drugs are usually used in follow up programs, however, the studies we investigated used different protocols. Enalapril (angiotensin-converting enzyme inhibitor) and verapamil (Ca++ channel blocker) caused hypertrophy to regress in LVH rats. The effects of enalapril and nifedipine (Ca++ channel blocker) were similar. Indapamina (diuretic) had a stronger effect than enalapril, and losartan (angiotensin II receptor type 1 (AT1) receptor antagonist) produced better results than atenolol (selective â1 receptor antagonist) with respect to LVH regression. CONCLUSION: The anti-hypertensive drugs induced various degrees of hypertrophic regression.
