Effects of prednisolone tapering on effectiveness of infliximab in patients with ulcerative colitis: data from a retrospective cohort.

BACKGROUND AND OBJECTIVE: The influence of concomitant prednisolone on clinical outcomes and safety in infliximab-treated ulcerative colitis (UC) patients is unknown. DESIGN, SETTING, PARTICIPANTS AND OUTCOME MEASURES: A retrospective cohort study was performed, including 147 UC patients treated with infliximab at a tertiary inflammatory bowel disease (IBD) centre. Primary outcome was corticosteroid-free clinical remission (CFCR) at week 14 and week 52. Patients were grouped according to prednisolone tapering regimens: standard (≤5 mg/week), fast (>5 mg/week), direct discontinuation or no prednisolone. Patients intolerant to corticosteroids and patients stopping corticosteroids in preparation for surgery including colectomy during their initial admission were excluded. RESULTS: There was no overall association between prednisolone exposure or no exposure and CFCR at weeks 14 or 52 of infliximab. The proportion of patients with C reactive protein ≤5 mg/L was higher in the standard tapering at week 14 as compared with faster regimens or no prednisolone. In subgroup analyses, the standard tapering was associated with a higher rate of CFCR at week 14 compared with the fast-tapering regimen in patients receiving ≥40 mg prednisolone at initiation of infliximab (64.3% vs 26.3%, p=0.04) and among patients admitted with acute severe UC (66.6% vs 23.5%, p<0.05). Similar data were seen at week 52. Prednisolone did not affect infliximab trough levels but increased infection rates (10/77 vs 2/70, p=0.03), in particular C. difficile infection. CONCLUSION: In UC patients with limited disease burden, prednisolone did not affect effectiveness of infliximab. However, patients with increased disease burden seem to benefit from corticosteroid combination therapy.

Mycophenolate mofetil vs. cyclophosphamide-based induction regimens for lupus nephritis: Outcomes at a tertiary care centre in Lahore, Pakistan.

Objectives: To compare the efficacy of mycophenolate mofetil with intravenous cyclophosphamideas induction therapy in lupus nephritis. METHODS: The observational, prospecrive, cohort study was conducted at the Rheumatology Department of Fatima Memorial Hospital, Lahore, Pakistan, from July 2016 to June 2019, and comprised lupus nephritis patients. For induction therapy, the patients were assigned at the discretion of the treating rheumatologist to mycophenolate mofetil group MMF, and intravenous cyclophosphamide group CYC. The latter group was further divided into NIH subgroup that received the therapy as per the protocol of the National Institutes of Health, and ELNT subgroup which recived the therapy as per the Euro Lupus Nephritis Trial protocol. Maintenance therapy in all groups was mycophenolate mofetil. Tacrolimus was added in case of non-response. The outcome was the achievement of complete renal response at 6, 12 and 24 months. Data was analysed using SPSS 26. RESULTS: Of the 131 patients, 126(96.2%) were females. The overall mean age was 27±7.7 years. There were 58(44.2%) patients in group MMF and 73(55.7%) in group CYC, which had subgroup NIH 46(63%) and subgrpup ELNT 27(37%). The complete renal response rates at 6, 12, and 24 months were 22 (43.1%), 35 (71.4%), and 40(83.3%) for group MMF; 5(12.5%), 9(22%) and 24 (58.5%) for subgroup NIH, and 6(26.1%), 8(36.4%) and 14(63.6%) for subgroup ELNT. Group MMF outcomes were significantly better than the rest (p<0.05). CONCLUSIONS: Mycophenolate mofetil induction therapy was more effective than intraveenous cyclophosphamide in terms of achieving remission at 6, 12 and 24 months.

Decitabine as epigenetic priming with CLAG induce improved outcome of relapsed or refractory acute myeloid leukemia in children.

BACKGROUND: Decitabine (DAC), a DNA methyltransferase inhibitor, has shown efficacy combined with chemotherapy for relapsed or refractory (R/R) acute myeloid leukemia (AML) in adults, but less is known about its efficacy in children. Accordingly, we conducted a study which involved a priming regimen consisting of DAC with cladribine, cytarabine, and granulocyte-stimulating factor (DAC-CLAG) and compared the efficacy and safety of this regimen with CLAG alone. METHODS: A total of 39 R/R AML children who received the CLAG or DAC-CLAG regimen in Shanghai Children's Hospital were retrospectively enrolled in this non-randomized study. These regimens were studied sequentially over time. Twenty-two patients received CLAG from 2015, while 17 patients were administered epigenetic priming with DAC before CLAG from 2020. Patients were subsequently bridged to stem cell transplantation (SCT) or consolidation chemotherapy. Complete remission (CR) and adverse effects were analyzed by Fisher's exact test, and survival was analyzed by the Kaplan-Meier method. RESULTS: DAC-CLAG conferred a numerically higher CR compared to CLAG (70.59% vs 63.64%; P = 0.740). High CR rates occurred in patients with good cytogenetics (P = 0.029) and prior induction without cladribine (P = 0.099). The 1-year event-free survival (EFS) was 64.71% ± 11.59% and 63.31% ± 10.35% in the DAC-CLAG and CLAG group (P = 0.595), and 1-year overall survival (OS) was 81.45% ± 9.72% and 77.01% ± 9.04%, respectively (P = 0.265). The 1-year OS and EFS after SCT were higher in the DAC-CLAG than in the CLAG cohort (100% vs 92.31% ± 7.39%, P = 0.072; 92.31% ± 7.39% vs 85.71% ± 9.35%, P = 0.158). Univariate analysis revealed that a good prognosis included good cytogenetics (P = 0.002), non-complex karyotype (P = 0.056), CR on reinduction (P < 0.0001), and bridging to SCT (P = 0.0007). Use of a hypomethylating agent (P = 0.049) and bridging to SCT (P = 0.011) were independent prognostic factors. Grade 3/4 hematologic toxicity and infection were the main adverse events. CONCLUSIONS: DAC prior to the CLAG regimen improved remission in pediatric R/R AML, and was feasible and well tolerated. CLAG ± DAC as a salvage therapy prior to SCT induced improved survival.

Barriers to clinical remission in severe asthma.

Severe asthma is associated with an increased risk for exacerbations, reduced lung function, fixed airflow obstruction, and substantial morbidity and mortality. The concept of remission in severe asthma as a new treatment goal has recently gained attention due to the growing use of monoclonal antibody therapies, which target specific pathologic pathways of inflammation. This review evaluates the current definitions of asthma remission and unveils some of the barriers for achieving this state in the severe asthma population. Although there is no unified definition, the concept of clinical remission in asthma should be based on a sustained period of symptom control, elimination of oral corticosteroid exposure and exacerbations, and stabilization of pulmonary function. The conjugation of these criteria seems a realistic treatment target in a minority of asthmatic patients. Some unmet needs in severe asthma may affect the achievement of clinical remission. Late intervention with targeted therapies in the severe asthma population may increase the risk of corticosteroid exposure and the development of irreversible structural airway changes. Moreover, airway infection is an important component in persistent exacerbations in patients on biologic therapies. Phenotyping exacerbations may be useful to guide therapy decisions and to avoid the liberal use of oral corticosteroids. Another challenge associated with the aim of clinical remission in severe asthma is the multifaceted interaction between the disease and its associated comorbidities. Behavioural factors should be evaluated in case of persistent symptoms despite optimised treatment, and assessing biomarkers and targeting treatable traits may allow for a more objective way of reaching remission. The concept of clinical remission will benefit from an international consensus to establish unifying criteria for its assessment, and it should be addressed in the future management guidelines.

Application of clinical decision support tools for predicting outcomes with vedolizumab therapy in patients with inflammatory bowel disease: A KASID multicentre study.

BACKGROUND/AIM: We aimed to validate clinical decision support tools (CDSTs) to predict real-life effectiveness of vedolizumab (VDZ) in patients with inflammatory bowel disease. METHODS: We retrospectively enrolled patients with Crohn's disease (CD) or ulcerative colitis (UC) treated with VDZ at 10 tertiary referral centres in Korea between January 2017 and November 2021. We assessed clinical remission (CREM) and response (CRES), corticosteroid-free clinical remission (CSF-CREM) and response (CSF-CRES), biochemical response based on C-reactive protein (BioRES[CRP]) and faecal calprotectin (BioRES[FC]), endoscopic healing (EH), and the need to optimise or switch drugs based on CDST-defined response groups. Additionally, the area under the receiver operating characteristics curve (AUC) for the CDSTs was calculated. RESULTS: We included 143 patients with CD and 219 with UC. We observed incremental trends on CSF-CRES at week 14 (W14) (ptrend = 0.004) and decreasing trends for the need to optimise or switch drugs (ptrend = 0.016) in CD from the low to high probability groups. Except for CSF-CREM at W54, we noticed incremental trends for all clinical responses at W14, W26 and W54 (ptrend <0.001) in UC. W26 and W54 BioRES[CRP] and W14 EH also showed increasing trends (ptrend <0.05) in UC. With increasing probabilities of response, drug optimisation or switching was less frequently required in UC (ptrend = 0.013). With 26 points cut-off, CDSTs effectively identified W14 CSF-CRES, W26 BioRES[CRP], BioRES[FC] and W54 BioRES[CRP] in UC, all with AUCs >0.600, whereas CDSTs showed poor accuracy in CD. CONCLUSIONS: CDSTs for VDZ had acceptable accuracy in predicting effectiveness outcomes including clinical and biochemical outcomes in UC. However, their utility in CD was limited.

Disease clearance in ulcerative colitis: A new therapeutic target for the future.

Advancements in murine modeling systems for ulcerative colitis have diversified our understanding of the pathophysiological factors involved in disease onset and progression. This has fueled the identification of molecular targets, resulting in a rapidly expanding therapeutic armamentarium. Subsequently, management strategies have evolved from symptomatic resolution to well-defined objective endpoints, including clinical remission, endoscopic remission and mucosal healing. While the incorporation of these assessment modalities has permitted targeted intervention in the context of a natural disease history and the prevention of complications, studies have consistently depicted discrepancies associated with ascertaining disease status through clinical and endoscopic measures. Current recommendations lack consideration of histological healing. The simultaneous achievement of clinical, endoscopic, and histologic remission has not been fully investigated. This has laid the groundwork for a novel therapeutic outcome termed disease clearance (DC). This article summarizes the concept of DC and its current evidence.

Reverse-engineered exclusive enteral nutrition in pediatric Crohn's disease: A pilot trial.

BACKGROUND: In pediatric Crohn's disease (CD), commercial formulas used as exclusive enteral nutrition (EEN) are effective at inducing remission. This study aims to assess the impact of a whole-food blended smoothie as EEN on CD activity and the intestinal microbiome. METHODS: A 4-week prospective trial assessed the impact of EEN with a whole-food smoothie on newly diagnosed mild-to-moderate active pediatric CD. The smoothie with a multivitamin were developed to meet age-appropriate nutritional requirements. Assessment over 4 weeks included Pediatric Crohn's Disease Activity Index (PCDAI), serum laboratories, fecal calprotectin (FCP), and stool collection for metagenomic shotgun sequencing and microbiota composition analysis. Clinical remission was defined as PCDAI ≤ 10 at week 4. RESULTS: Ten participants were enrolled with median age 14.5 years, and 8 completed the trial. Baseline mean PCDAI was 26.3 ± 9.1 and mean FCP 1149 ± 718 µg/g. At week 4, 80% of participants achieved clinical remission. FCP decreased by over half in 60% of participants, with FCP below 250 µg/g in 60% and below 100 µg/g in 40%. Microbiome analysis showed a significant increase in species richness over 4 weeks (p = 0.01). Compared to baseline, the relative abundance at week 2 and at week 4 was significantly increased for Bifidobacterium and Streptococcus and decreased for Blautia (p < 0.05 for all). CONCLUSION: A whole-food blended smoothie was effective for inducing clinical remission and decreasing FCP in pediatric CD similar to commercial EEN formulas. Further research may give insight into data-driven whole-food dietary approaches for CD management. CLINICALTRIALS: gov NCT03508193.

Real-world efficacy and safety of tofacitinib treatment in Asian patients with ulcerative colitis.

BACKGROUND: Real-world data on tofacitinib (TOF) covering a period of more than 1 year for a sufficient number of Asian patients with ulcerative colitis (UC) are scarce. AIM: To investigate the long-term efficacy and safety of TOF treatment for UC, including clinical issues. METHODS: We performed a retrospective single-center observational analysis of 111 UC patients administered TOF at Hyogo Medical University as a tertiary inflammatory bowel disease center. All consecutive UC patients who received TOF between May 2018 and February 2020 were enrolled. Patients were followed up until August 2020. The primary outcome was the clinical response rate at week 8. Secondary outcomes included clinical remission at week 8, cumulative persistence rate of TOF administration, colectomy-free survival, relapse after tapering of TOF and predictors of clinical response at week 8 and week 48. RESULTS: The clinical response and remission rates were 66.3% and 50.5% at week 8, and 47.1% and 43.5% at week 48, respectively. The overall cumulative clinical remission rate was 61.7% at week 48 and history of anti-tumor necrosis factor-alpha (TNF-α) agents use had no influence (P = 0.25). The cumulative TOF persistence rate at week 48 was significantly lower in patients without clinical remission than in those with remission at week 8 (30.9% vs 88.1%; P < 0.001). Baseline partial Mayo Score was significantly lower in responders vs non-responders at week 8 (odds ratio: 0.61, 95% confidence interval: 0.45-0.82, P = 0.001). Relapse occurred in 45.7% of patients after TOF tapering, and 85.7% of patients responded within 4 wk after re-increase. All 6 patients with herpes zoster (HZ) developed the infection after achieving remission by TOF. CONCLUSION: TOF was more effective in UC patients with mild activity at baseline and its efficacy was not affected by previous treatment with anti-TNF-α agents. Most relapsed patients responded again after re-increase of TOF and nearly half relapsed after tapering off TOF. Special attention is needed for tapering and HZ.

Real-world effectiveness of ustekinumab and vedolizumab in TNF-exposed pediatric patients with ulcerative colitis.

OBJECTIVES: Vedolizumab (VDZ) and ustekinumab (UST) are second-line treatments in pediatric patients with ulcerative colitis (UC) refractory to antitumor necrosis factor (anti-TNF) therapy. Pediatric studies comparing the effectiveness of these medications are lacking. Using a registry from ImproveCareNow (ICN), a global research network in pediatric inflammatory bowel disease, we compared the effectiveness of UST and VDZ in anti-TNF refractory UC. METHODS: We performed a propensity-score weighted regression analysis to compare corticosteroid-free clinical remission (CFCR) at 6 months from starting second-line therapy. Sensitivity analyses tested the robustness of our findings to different ways of handling missing outcome data. Secondary analyses evaluated alternative proxies of response and infection risk. RESULTS: Our cohort included 262 patients on VDZ and 74 patients on UST. At baseline, the two groups differed on their mean pediatric UC activity index (PUCAI) (p = 0.03) but were otherwise similar. At Month 6, 28.3% of patients on VDZ and 25.8% of those on UST achieved CFCR (p = 0.76). Our primary model showed no difference in CFCR (odds ratio: 0.81; 95% confidence interval [CI]: 0.41-1.59) (p = 0.54). The time to biologic discontinuation was similar in both groups (hazard ratio: 1.26; 95% CI: 0.76-2.08) (p = 0.36), with the reference group being VDZ, and we found no differences in clinical response, growth parameters, hospitalizations, surgeries, infections, or malignancy risk. Sensitivity analyses supported these findings of similar effectiveness. CONCLUSIONS: UST and VDZ are similarly effective for inducing clinical remission in anti-TNF refractory UC in pediatric patients. Providers should consider safety, tolerability, cost, and comorbidities when deciding between these therapies.

Dose Tapering and Discontinuation of Biologic DMARDs in Axial Spondyloarthritis: A Narrative Review (2023 SPARTAN Annual Meeting Proceedings).

PURPOSE OF REVIEW: Limited data is available for tapering or discontinuation of biologic therapy in patients with axSpA who are in disease remission. The current review concentrates on published studies regarding dose tapering or withdrawal of biologics in axSpA. RECENT FINDINGS: Recent evidence in light of randomized controlled trials suggests that tapering of b-DMARDs is a feasible strategy to maintain remission or low disease activity in axSpA patients. TNF inhibitors were the studied biologics in most of these trials. The disease flare rates were comparable to those maintained on standard dose in most of these studies, although with variable tapering strategies and follow-up. Additionally, the duration of disease in remission prior to tapering, studied primary outcome, and flare definitions were heterogeneous. Female sex, HLA-B*27 negativity, high physician global score, and high CRP were negative predictors of successful tapering, but not consistently reported in all the trials. Although designed to address efficacy, there were no safety concerns with b-DMARD tapering. Withdrawal or complete discontinuation of biologics met with increased risk of flares compared to standard dosing. Tapering of TNF inhibitors may be feasible in certain axSpA patients with an acceptable disease state; however, discontinuation is not currently recommended owing to increased risk of flare. Future studies with axSpA patients with longer remission duration prior to taper and different doses and types of b-DMARDs may provide more guidance.

Efficacy of infliximab after loss of response of/intolerance to adalimumab in pediatric Crohn's disease: A retrospective multicenter cohort study of the "GETAID pédiatrique".

BACKGROUND: Infliximab (IFX) and adalimumab (ADA) are recommended for induction and maintenance of remission in pediatric Crohn's disease (CD). ADA is now often used in first line due to its efficacy and tolerability, but a loss of response (LOR) can occur over time. The aim was to assess the efficacy of IFX as second line therapy after LOR or intolerance to ADA in pediatric CD patients at 1 year. METHODS: We conducted a retrospective and multicenter study in France among the "GETAID pédiatrique" centers between April 2019 and April 2022. CD patients under 18 years old and treated with IFX after ADA failure or intolerance were included. We collected anthropometric, clinical, and biological data at baseline (start of IFX), at 6 and 12 months. Clinical remission was defined by a Weighted Pediatric CD Activity Index (wPCDAI) score less than 12.5 points. RESULTS: Of the 32 patients included in our study, 27 (84.4%) were still on IFX at 12 months of the switch. Among them, 13 had discontinued ADA because of a LOR, 12 for insufficient response and 2 due to primary nonresponse. At M12, 22 patients were in corticosteroid free clinical remission (68.7%). Under IFX, the wPCDAI decreased over time (47.5 ± 24.1, 16.6 ± 21.2 and 9.7 ± 19.0 at M0, M6 and M12 respectively). The only factor associated with clinical remission at 12 months was absence of perianal disease at the end of the IFX induction. CONCLUSIONS: IFX is effective in maintaining remission at 1 year in pediatric CD patients experiencing a LOR or intolerance with ADA, and IFX could be an interesting therapeutic choice instead of other biologics in this situation.

Genetic biomarkers of methotrexate response and safety in Crohn's disease: Data from the Spanish ENEIDA registry.

AIMS: Methotrexate (MTX) is used to induce and maintain remission in patients with steroid-dependent Crohn's disease (CD). Despite its proven efficacy, its use is limited due to associated adverse events. Polymorphisms involving folate pathway genes might influence MTX efficacy and toxicity. We aimed to assess the impact of certain polymorphisms on the therapeutic outcomes of MTX in CD. METHODS: Patients with CD who exclusively followed MTX monotherapy and fulfilled inclusion criteria were identified from the GETECCU ENEIDA registry. Variants of ATIC, DHFR, MTHFR, SLC19A1, ABCB1 and ABCC3 genes were analysed and their association with efficacy and toxicity was assessed. RESULTS: A total of 129 patients were included in the analysis. MTX was used at a median weekly dose of 25 mg (interquartile range, 15-25 mg) and a median time of 14 months (interquartile range, 4-52 months). Thirty-seven percent of the patients achieved disease remission with MTX monotherapy, while 34% were nonresponders (MTX failure). MTX-related toxicity occurred in 40 patients (30%), leading to MTX discontinuation in 19%. DHFR rs408626 (odds ratio [OR] 3.12, 95% confidence interval [CI] 1.22-7.69; P = .017) and MTHFR rs1801133 (OR 2.86, 95% CI 1.23-6.68; P = .015) variants, and smoking (OR 2.61, 95% CI 1.12-6.05; P = .026) were associated with a higher risk of MTX failure. Additionally, the MTHFR rs1801131 variant was associated with a higher risk of MTX-related adverse effects (OR 2.78, 95% CI 1.26-6.13, P = .011). CONCLUSION: Our study shows that variants of MTHFR and DHFR genes may be associated with MTX efficacy and adverse events in patients with CD.

The clinical efficacy and safety of granulocyte and monocyte adsorptive apheresis in patients with Crohn's disease: A multicenter retrospective pilot study.

INTRODUCTION: A remission induction therapy of granulocyte and monocyte adsorptive apheresis (GMA) was given to patients with Crohn's disease (CD). However, establishing an appropriate treatment strategy for GMA in patients with CD remains unclear. METHODS: This study evaluated the clinical efficacy and subsequent clinical progression after GMA in patients with CD who underwent GMA in seven independent institutions in Japan from 2010 to 2023. RESULTS: Sixteen patients were enrolled. The overall remission and response rates were 25.0% and 68.8%, respectively. All patients responding to GMA received biologics that were continuously used and 36.4% of patients remained on the same biologics 52 weeks after GMA. Notably, all patients who continued the same biologics had previously experienced a loss of response to biologics. CONCLUSION: GMA may exhibit effectiveness even in cases with refractory CD. Moreover, it represents a potential novel therapeutic option for refractory CD with loss of response to biologics.

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.

Increased remission with fewer corticosteroids and more biologics in rheumatoid arthritis at 7-year follow-up in real-life conditions.

Remission in rheumatoid arthritis (RA) is an important therapeutic target that is not easy to achieve in real-life conditions. Some prognostic factors have been identified but the literature is variable. The objectives of this study were to evaluate the remission rate and the maintenance of remission in patients with RA over 7 years of follow-up in real-life conditions and to identify prognostic factors of long-term remission. Patients with RA seen at the Poitiers University Hospital were identified and clinical and biological data were collected. Data were analysed after 1 year and 7 years. Twice as many patients were in remission at 7 years than at 1 year of follow-up. 48.6% of patients who were not in remission at 1 year obtained remission at 7 years of follow-up. Patients achieving remission were more often receiving coprescription of csDMARDs and bDMARDs. Patients not in remission at 7 years were given more corticosteroids at higher doses. After 7 years of follow-up, low initial disease activity and use of csDMARDs and bDMARDs appeared to be independent positive predictive factors. Once obtained at one year, remission was maintained for 76% of our patients. As a conclusion, modern management of RA, whatever disease duration, leads to remission rates similar to those of early RA after 7 years of follow-up.

Approach to switching biologics in juvenile idiopathic arthritis: a real-life experience.

The primary aim of the treatment of juvenile idiopathic arthritis (JIA) is complete remission and minimizing the development of complications. Though biologic agents (BAs) provide better disease control, data related to BA switching patterns in JIA patients are scarce. This study aimed to determine the BA switching patterns in JIA patients. The study included children with JIA that received ≥ 1 BAs. Disease activity was evaluated based on the juvenile arthritis disease activity score 71 (JADAS71). Demographic data, clinical and laboratory findings, BA switching patterns, and the rationales for BA switching were recorded. The study included 177 (82 female and 95 male) JIA patients that received ≥ 1 BAs. Mean age at diagnosis of JIA was 9.1 ± 4.9 years. BAs were prescribed a median of 14 months (range: 3-66 months) after diagnosis. Among the 177 patients, 31 (17.5%) required BA switching a median 10.5 months (range: 3-38 months) after initiation of the first BA. Among all the BAs that were switched to after administration of the first BA, tocilizumab was the most commonly switched (n = 15). The most common reason for BA switching was inadequate response (n = 29). BAs were switched 2 times in 5 patients and 3 times in 1 patient. When patients that switched BAs 1 time were compared to those that switched 2 and 3 times there were not any differences in terms of JIA types, whereas those that switched 2 and 3 times had a higher active joint count and JADAS71 score after 6 months of initiation of the first BA. As some of the JIA patients could not achieve remission despite using the prescribed BA, BA switching was required. Herein, we provide data on both BA switching patterns and requirements, which may improve the management of JIA patients.

Propensity-score matched analysis of the efficacy of maintenance/continuous therapy in newly diagnosed patients with multiple myeloma: a multicenter retrospective collaborative study of the Japanese Society of Myeloma.

BACKGROUND: Maintenance ± consolidation or continuous therapy is considered a standard of care for both transplant-eligible and -ineligible patients with multiple myeloma (MM). However, long-term benefits of such therapy have not yet been clarified in the context of clinical practice. PURPOSE: To clarify the efficacy of maintenance/continuous approach, we retrospectively analyzed the cohort data of newly diagnosed MM patients by propensity-score matching based on age, gender, revised International Staging System (R-ISS) stage, and implementation of transplantation to reduce the bias due to confounding variables. FINDINGS: Among 720 patients, 161 were identified for each of the maintenance and no maintenance groups. Maintenance/continuous therapy employed immunomodulatory drugs (n = 83), proteasome inhibitors (n = 48), combination of both (n = 29), or dexamethasone alone (n = 1). Progression-free survival (PFS) was significantly prolonged in the maintenance group compared with the no maintenance group (median 37.7 and 21.9 months, p = 0.0002, respectively). Prolongation of PFS was observed in both transplanted and non-transplanted patients (p = 0.017 and p = 0.0008, respectively), with standard risk (p < 0.00001), R-ISS stage I (p = 0.037) and stage II (p = 0.00094), and those without obtaining complete response (p = 0.0018). There was no significant benefit in overall survival (OS), but it tended to be better in the maintenance group in non-transplanted patients. Regarding the treatment pattern, the substitution or addition of drugs different from the induction therapy and the combination with immunomodulatory drugs and proteasome inhibitors appeared to be more beneficial for PFS but not OS. CONCLUSION: These results support the benefit of current maintenance/continuous approach in routine clinical practice in the management of MM.

Consensus-based recommendations on the diagnosis, referral and clinical management of patients with psoriatic arthritis.

Psoriatic arthritis (PsA) is a highly heterogeneous disease with complex manifestations. Limited understanding of the disease and non-availability of local guidelines pose challenges in the management of PsA in Saudi Arabia. Therefore, this expert consensus is aimed to provide recommendations on the management of patients with PsA, including referral pathway, definition of remission and treat-to-target (T2T) approach. A Delphi technique of consensus development was used involving an expert panel comprised of 10 rheumatologists, one dermatologist and one family physician. Based on the review of available published evidence and the opinions of clinical experts, key recommendations were developed. A consensus was achieved in defining the following: management guideline adaptable for Saudi Arabia, most useful screening tool, laboratory investigations, imaging tests and criteria for referring suspected PsA patients to a rheumatologist. In addition, an agreement was achieved in defining the T2T strategy and remission for the clinical management of PsA. Overall, these recommendations provide an evidence-based framework for the management of PsA patients in Saudi Arabia.
