RESUMO
The first-line treatment for autoimmune hepatitis involves the use of prednisone or prednisolone either as monotherapy or in combination with azathioprine (AZA). Budesonide has shown promise in inducing a complete biochemical response (CBR) with fewer adverse effects and is considered an optional first-line treatment, particularly for patients without cirrhosis; however, it is worth noting that the design of that study favored budesonide. A recent real-life study revealed higher CBR rates with prednisone when equivalent initial doses were administered. Current guidelines recommend mycophenolate mofetil (MMF) for patients who are intolerant to AZA. It is important to mention that the evidence supporting this recommendation is weak, primarily consisting of case series. Nevertheless, MMF has demonstrated superiority to AZA in the context of renal transplant. Recent comparative studies have shown higher CBR rates, lower therapeutic failure rates, and reduced intolerance in the MMF group. These findings may influence future guidelines, potentially leading to a significant modification in the first-line treatment of autoimmune hepatitis. Until recently, the only alternative to corticosteroids was lifelong maintenance treatment with AZA, which comes with notable risks, such as skin cancer and lymphoma. Prospective trials are essential for a more comprehensive assessment of treatment suspension strategies, whether relying on histological criteria, strict biochemical criteria, or a combination of both. Single-center studies using chloroquine diphosphate have shown promising results in significantly reducing relapse rates compared to placebo. However, these interesting findings have yet to be replicated by other research groups. Additionally, second-line drugs, such as tacrolimus, rituximab, and infliximab, should be subjected to controlled trials for further evaluation.
RESUMO
Objective: To evaluate the application of proactive pro-drug therapy (TDM) at week six in users of infliximab therapy in ulcerative colitis patients and to analyze the need for further disease optimization. Method: This is a retrospective analysis that will be carried out simultaneously at the Hospital de Clínicas de Passo Fundo and at the Endoclin Diagnostic Center in the city of Passo Fundo, with secondary data collection between January 2020 and May 2022. The sample included patients from both sexes, regardless of age, who are being followed up in the services mentioned above, by signing the informed Free and Clarified Consent Term. Results: 63.2% of patients required optimization of their treatment based on the serum level assessment at week six. Conclusion: Proactive TDM performed at week six benefits patients in order to complete indications for treatment to avoid lack of drug response and complications from the disease. (AU)

Abstract Introduction: The use of Rituximab (RTX) in glomerular diseases (GD) has increased in the past years, although it is still only used in a small fraction of patients. Methods: A single center retrospective study of adult patients with membranous nephropathy (MN), focal segmental glomerulosclerosis (FSGS), lupus nephritis (LN), and vasculitis treated with RTX as first or second-line therapy was conducted at our center from 2010 to 2020. Results: We identified 19 patients; 36.8% had MN and 25.0% each had FSGS, LN, and vasculitis. RTX was first-line therapy in 26.3% of patients and in 73.7% it was second-line therapy. Mean follow-up time was 7.7 ± 7.2 years. In MN, 2 patients (28.6%) had complete remission (CR), 2 patients (28.6%) had partial remission (PR), and 3 patients (42.9%) had no response (NR). In FSGS, 2 patients (50.0%) presented CR, 1 patient (25.0%) had no response, and 1 patient had renal deterioration. Two patients (50.0%) had a LN class IV with a CR after RTX, 1 patient with LN class IIIC/V had no response, and 1 patient with LN class II had renal deterioration. In vasculitis, 3 patients (75.0%) presented CR and 1 patient had PR. Infusion reactions were present in 2 patients (10.5%) and one patient had multiple infectious complications. Conclusions: The efficacy of RTX in treating different types of immune-mediated GD has been demonstrated with different response rates, but an overall safe profile. In our case series, the results are also encouraging. Longitudinal studies are needed to better understand the effect of RTX in GD.
Resumo Introdução: O uso de Rituximab (RTX) em doenças glomerulares (DG) aumentou nos últimos anos, embora ainda utilizado apenas em uma pequena fração de pacientes. Métodos: Conduzimos em nosso centro, de 2010-2020, um estudo retrospectivo de único centro de pacientes adultos com nefropatia membranosa (NM), glomeruloesclerose segmentar focal (GESF), nefrite lúpica (NL) e vasculite tratada com RTX como terapia de primeira ou segunda linha. Resultados: Identificamos 19 pacientes; 36,8% tinham NM; 25,0% cada apresentava GESF, NL e vasculite. RTX foi terapia de primeira linha em 26,3% dos pacientes e em 73,7% foi terapia de segunda linha. O tempo médio de acompanhamento foi 7,7 ± 7,2 anos. Em NM, 2 pacientes (28,6%) tiveram remissão completa (RC), 2 pacientes (28,6%) remissão parcial (RP), e 3 pacientes (42,9%) não tiveram resposta (NR). Na GESF, 2 pacientes (50,0%) apresentaram RC, 1 paciente (25,0%) não teve resposta e, 1 paciente, deterioração renal. Dois pacientes (50,0%) apresentaram NL classe IV com RC após RTX, 1 paciente com NL classe IIIC/V não teve resposta, e 1 paciente com NL classe II apresentou deterioração renal. Na vasculite, 3 pacientes (75,0%) apresentaram RC e 1 paciente RP. Reações à infusão ocorreram em 2 pacientes (10,5%) e um paciente apresentou múltiplas complicações infecciosas. Conclusões: A eficácia do RTX em tratar diferentes tipos de DG imunomediada tem sido demonstrada com diferentes taxas de resposta, mas com perfil geral seguro. Em nossa série de casos, os resultados também são encorajadores. Estudos longitudinais são necessários para compreender melhor o efeito do RTX na DG.
RESUMO
INTRODUCTION: Several treatments have been used to reduce inflammation and to reverse epithelial alterations in actinic cheilitis (AC). AIM: A systematic review was conducted to analyze the potential of topical treatments for remission and clinical improvement of AC as well as patient acceptability. METHODS: A systematic review of clinical trials was conducted following the PICO strategy to answer the following question: Are topical anti-inflammatory and antineoplastic agents effective in the treatment of actinic cheilitis? The quality of the studies was assessed by ROB-2, and the certainty of evidence was rated by GRADE guidelines. RESULTS: Eight clinical trials were selected, including four that investigated the use of anti-inflammatory drugs and four use of antineoplastic agents. The use of 3% diclofenac sodium was associated with partial remission of AC, while 5% imiquimod and ingenol mebutate promoted complete remission. Furthermore, 5% fluorouracil was the drug most associated with complications during treatment. Diclofenac sodium (3%) and fludroxycortide showed the best acceptance by the patients, especially in terms of symptom relief and comfort provided. CONCLUSION: The anti-inflammatory and antineoplastic agents analyzed largely provided good clinical outcomes, with evidence of remission of AC lesions, development of few local adverse reactions during treatment, and good patient adherence.

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

Introduction: Acromegaly prevalence is 35-70 / million. Transsphenoidal surgery is the first-line treatment, with a remission rate of 80% for microadenomas and 50% for macroadenomas. Our aim was to evaluate the surgical results in Córdoba and determine predictive remission factors due to the lack of records. Methods: Retrospective-descriptive study of patients with surgery as the first therapeutic line. Remission criteria: IGF1 normalization for age/sex, with GH ≤1.0 g/L. Test X2 and Fisher's exact test with p<0.05. Results: 38 patients were included: 61% women and 39% men; Average age 45 years. Most frequent chief complaint: headache and acral growth (26%), visual disturbances (20%). Macroadenomas were the 84% of the tumors. Of 37 patients, 54% underwent microscopic surgery, 38% endoscopic and 8% transcranial. The 29% of patients showed post-operative complications and diabetes insipidus was the most frequent (10%). The percentage of them was: 33% transcranial surgery, 29% endoscopic and 25% microscopic (p = 0.557). The biochemical remission at 6 months was 34% and at 12 months 55% (p= 0.0001). No significant differences between the endoscopic and microscopic approach (p = 0.071). Of 36 patients, 31% showed complete tumor resection. The subjective clinical improvement was 88%. There weren´t predictive remission factors with significant differences. Conclusion: The surgical biochemical remission was similar to the bibliography. We didn´t find predictive remission factors but a larger number of patients could modify these results.
Introducción: La acromegalia tiene una prevalencia de 35-70/millón. La cirugía transesfenoidal es el tratamiento de elección, siendo la tasa de remisión del 80% en microadenomas y 50% en macroadenomas. Debido a la falta de registros, nos propusimos evaluar los resultados quirúrgicos en Córdoba y determinar factores predictivos de remisión. Métodos: Estudio retrospectivo-descriptivo de pacientes con cirugía como primera línea terapéutica. Criterios de remisión: normalización de IGF1 para edad/sexo, con GH ≤1,0 g/L.Test X2 y test exacto de Fisher y p<0,05. Resultados: Se incluyeron 38 pacientes: 61% mujeres y 39% hombres; edad promedio 45 años. Motivos de consulta más frecuentes: cefalea y crecimiento acral (26%), alteraciones visuales (20%). El 84% de los tumores fueron macroadenomas. De 37 pacientes, 54% se sometieron a cirugía microscópica, 38% endoscópica y 8% transcraneal. El 29% evidenció complicaciones postquirúrgicas, siendo la diabetes insípida la más frecuente (10%). El porcentaje de las mismas fue: cirugía transcraneal el 33%, endoscópica 29% y microscópica 25% (p= 0,557). La remisión bioquímica a los 6 meses fue de 34% y a los 12 meses 55% (p=0,0001). Sin diferencias significativas entre la vía endoscópica y microscópica (p=0,071). De 36 pacientes el 31% evidenció resección tumoral completa. La mejoría clínica subjetiva fue del 88%. No hubo factores predictivos de remisión bioquímica estadísticamente significativos. Conclusión: La remisión bioquímica con la cirugía fue similar a la bibliografía. No encontramos factores predictivos de remisión pero un número mayor de casos podría modificar estos resultados.

The effects of dose reduction or spacing of all types of biologics in rheumatoid arthritis has not been consistently assessed in systematic reviews. We aimed to assess the effects of biologics reduction compared with dose maintenance in patients with rheumatoid arthritis in low disease activity or remission. We performed a systematic review with meta-analysis according to a previously registered protocol (PROSPERO registration: CRD42017069080); and searched MEDLINE, Embase, Scopus, Cochrane Library and trial registers up to July, 2020. Two researchers selected, extracted and assessed the risk of bias of controlled trials that randomized patients to reduction/spacing or dose maintenance of biologics. Low disease activity, disability and other clinically important outcomes were summarized in random effect meta-analyses. We rated the certainty of evidence according to the Grading of Recommendations Assessment, Development, and Evaluation approach. We included ten studies (n = 1331 patients), which assessed reduction or spacing of abatacept, adalimumab, certolizumab pegol, etanercept, or tocilizumab. Risk of bias was high in over half of trials, mainly due to lack of blinding. No statistically significant difference was found in low disease activity (RR = 0.90; 95% CI 0.78-1.04; I2 = 60%, very low certainty), and other outcomes. Subgroup analysis of blinded studies led to homogeneous results, which remained heterogeneous in open-label studies. Reduction or spacing biologics did not affect disease activity and other important outcome. Changes in the doses regimen should consider patient preferences, considering the low certainty of evidence.

Introducción: la Ley Ricarte Soto (LRS) permite a pacientes con artritis reumatoide refractaria acceder a medicamentos biológicos. Sin embargo con esta regulación los pacientes inician éstos con actividad alta de enfermedad por un período prolongado, luego de recibir al menos 3 fármacos sintéticos. Previo a la implementación de esta ley no era necesario cumplir estos requisitos. Objetivos:comparar la respuesta a tratamiento lograda con el uso de medicamentos biológicos según niveles de actividad al inicio mediante la comparación de pacientes con biológicos antes y después de la LRS. Métodos: tomando datos del Programa de atención de pacientes con artritis reumatoide de la Red de Salud UC-Christus se compraró grupos de pacientes que accedieron a biológicos pre y post implementación de la LRS. Se analizó el cambio en DAS28 y la categorización de actividad de enfermedad según DAS28. Se realizó una regresión lineal evaluando edad, seropositividad y DAS28 pre tratamiento. Resultados: se encontró una diferencia significativa en el cambio de DAS28 a los 6 meses de tratamiento (p=0,02) y en la regresión solo con el DAS28 pre tratamiento (p=0,00). Dentro del grupo de pacientes que requirió cambio de biológico, los pacientes post ley iniciaron la terapia más activos y presentaban mayor persistencia de actividad severa a los 6 meses de tratamiento (11% vs 25%).Conclusiones: si bien el nivel de actividad al inicio no influyó en la respuesta a los 6 meses de tratamiento, si influyó en la persistencia de actividad severa en quienes requirieron cambio de biológico.
Introduction: Chilean regulations (Ley Ricarte Soto (RS) allow patients with refractory rheumatoid arthritis to have access to biological agents, but because of the requirements of the law, they spend a long period with active disease. Objectives: To compare the effective-ness of treatment with biological agents according to baseline disease activity by comparing subjects initiating biologics previous to and after ley RS. Methods: Using data from the rheumatoid arthritis clinic at Red Salud UC-Christus, we compared groups of patients who had access to biological agents before and after the implementation of the RS law. Change in DAS 28 was analyzed as well as disease activity categories according to DAS 28. We performed linear regression evaluating age, seropositivity, and baseline DAS28. Results: We found a significant difference in the DAS28 score delta at six months of treatment (p=0.02). In linear statistically significant association in the treatment response with the pre-treatment DAS28 (p=0.00), but in the group of patients that required more than one biological agent, the post-LRS group had a higher pre-treatment DAS28 and a higher rate of high disease activity (11% vs. 25%) after six months of treatment. Discussion: Although the baseline disease activity level did not influence the final response to treatment, it had an impact on the persistence of severe activity in patients that required more than one biologic agent

Objective: German psychiatrist Kurt Schneider proposed the concept of first-rank symptoms (FRS) of schizophrenia in 1959. However, their relevance for diagnosis and prediction of treatment response are still unclear. Most studies have investigated FRS in chronic or medicated patients. The present study sought to evaluate whether FRS predict remission, response, or improvement in functionality in antipsychotic-naive first-episode psychosis. Methods: Follow-up study of 100 patients at first episode of psychosis (FEP), with no previous treatment, assessed at baseline and after 2 months of treatment. The participants were evaluated with the standardized Positive and Negative Syndrome Scale (PANSS) and Global Assessment of Functioning (GAF) and for presence of FRS. Results: Logistic regression analysis showed that, in this sample, up to three individual FRS predicted remission: voices arguing, voices commenting on one's actions, and thought broadcasting. Conclusion: Specific FRS may predict remission after treatment in FEP patients. This finding could give new importance to Kurt Schneider's classic work by contributing to future updates of diagnostic protocols and improving estimation of prognosis.

ABSTRACT While first-line induction therapy for patients with multiple myeloma has changed over the years, autologous hematopoietic stem cell transplantation still plays a significant role, improving both depth of response and progression-free survival of myeloma patients. Our 25-year experience in mobilizing hematopoietic stem and progenitor cells for 472 transplant-eligible myeloma patients was retrospectively reviewed. Patients were stratified according to the remission induction therapy received, and the outcomes were compared among the cohorts that received vincristine, adriamycin and dexamethasone (VAD) (n = 232), bortezomib and dexamethasone (BD) (n = 86), cyclophosphamide, bortezomib and dexamethasone (CyBorD) (n = 82) and other regimens (n = 67). Cyclophosphamide plus granulocyte colony-stimulating factor was the predominant mobilization regimen given. A greater number of CD34+ cells (9.9 × 10E6/kg, p = 0.026) was collected with less hospital admissions in BD patients (13%, p = 0.001), when compared to those receiving VAD (7.5 × 10E6/kg, 29%), CyBorD (7.6 × 10E6/kg, 19%), or other regimens (7.9 × 10E6/kg, 36%). Induction therapy did not influence the overall rate of unscheduled visits or the length of hospitalization because of complications following mobilization. The myeloma response was not significantly deepened following the cyclophosphamide administered for mobilization. This analysis demonstrates the importance of monitoring the impact of initial treatment on downstream procedures such as stem cell mobilization and collection.
