RESUMEN

OBJECTIVES: To explore the agreement between patient-reported flare status and clinically significant flare status in patients with rheumatoid arthritis (RA) in sustained remission. METHOD: Patients with RA in remission for ≥12 months on stable treatment were included in the ARCTIC REWIND tapering trials and pooled 12-month data used in current analyses. Patient-reported flare status was assessed according to the Outcome Measures in Rheumatology flare questionnaire; 'Are you having a flare of your RA at this time?' (yes/no). A clinically significant flare was defined as a combination of Disease Activity Score (DAS) >1.6, increase in DAS of ≥0.6 and 2 swollen joints, or the rheumatologist and patient agreed that a clinically significant flare had occurred. Agreement coefficient, sensitivity, specificity and predictive values of patient-reported flare status with regard to clinically significant flare status were determined. RESULTS: Of 248 patients, 64% were women, age 56.1 (11.8) years, disease duration 4.1 (2.8-7.4) years, DAS 0.8 (0.3). 35% of patients reported a flare at least once, clinically significant flares were recorded in 21%. 48/53 clinically significant flares (91%) led to an intensification of disease-modifying antirheumatic drugss. In 621/682 (91%) visits, patient-reported and clinically significant flare status were in agreement, agreement coefficient 0.89. Sensitivity and specificity were both 91%, positive predictive value of patient-reported flare status 46% and negative predictive value 99%. CONCLUSION: Among patients in sustained remission, patient-reported flare status was accurate in ruling out a clinically significant flare. About half of the patient-reported flares were assessed to be clinically significant. These findings support a potential for using patient-reported flare status in remote monitoring of patients with RA in sustained remission.

RESUMEN

Partial remission (PR) occurs in only half of people with new-onset type 1 diabetes (T1D) and corresponds to a transient period characterized by low daily insulin needs, low glycemic fluctuations and increased endogenous insulin secretion. While identification of people with newly-onset T1D and significant residual beta-cell function may foster patient-specific interventions, reliable predictive biomarkers of PR occurrence currently lack. We analyzed the plasma of children with new-onset T1D to identify biomarkers present at diagnosis that predicted PR at 3 months post-diagnosis. We first performed an extensive shotgun proteomic analysis using Liquid Chromatography-Tandem-Mass-Spectrometry (LCMS/MS) on the plasma of 16 children with new-onset T1D and quantified 98 proteins significantly correlating with Insulin-Dose Adjusted glycated hemoglobin A1c score (IDAA1C). We next applied a series of both qualitative and statistical filters and selected protein candidates that were associated to pathophysiological mechanisms related to T1D. Finally, we translationally verified several of the candidates using single-shot targeted proteomic (PRM method) on raw plasma. Taken together, we identified plasma biomarkers present at diagnosis that may predict the occurrence of PR in a single mass-spectrometry run. We believe that the identification of new predictive biomarkers of PR and ß-cell function is key to stratify people with new-onset T1D for ß-cell preservation therapies.

RESUMEN

INTRODUCTION: Graves' disease (GD) is an autoimmune disorder characterized by hyperthyroidism due to increased thyroid-stimulating hormone receptor antibodies (TRAb).The treatment of GD often consists of radioactive iodine therapy, anti-thyroid drugs (ATD), or thyroidectomy. Since few studies have collected data on remission rates after treatment with ATD in Saudi Arabia, our study aimed to assess the efficacy and the clinical predictors of GD long-term remission with ATD use. METHOD: We conducted a retrospective chart review study of 189 patients with GD treated with ATD between July 2015 and December 2022 at the endocrine clinics in King Abdulaziz Medical City in Riyadh. All GD patients, adults, and adolescents aged 14 years and older who were treated with ATD during the study period and had at least 18 months of follow-up were included in the study. Patients with insufficient follow-up and those who underwent radioactive iodine (RAI) therapy or thyroidectomy as first-line therapy for GD were excluded from the study. RESULTS: The study sample consisted of 189 patients, 72% of whom were female. The patients' median age was 38years (33, 49). A total of 103 patients (54.5%) achieved remission. The median follow-up period for the patients was 22.0 months (9, 36). Patients who achieved remission had lower mean free T4 levels (25.8pmol/l ± 8.93 versus 28.8pmol/l ± 10.82) (P value = 0.038) and lower median TRAb titer (5.1IU/l (2.9, 10.7)) versus (10.5IU/l (4.2, 22.5)) (P value = 0.001) than patients who did not achieve remission. Thirty-five out of 103 patients who achieved remission (34%) relapsed after ATD discontinuation. The patients who relapsed showed higher median thyroid uptake on 99mTc-pertechnetate scan than patients who did not relapse: 10.3% (5.19, 16.81) versus 6.0% (3.09, 12.38), with a P value of 0.03. They also received ATD for a longer period, 40.0 months (29.00, 58.00) versus 25.0 months (19.00, 32.50), with a P value of < 0.0001. CONCLUSION: The remission of GD was achieved in approximately half of the patients treated with ATD; however, approximately one-third of them relapsed. Lower Free T4 and TRAb levels at diagnosis were associated with remission. Longer ATD use and higher thyroid uptake upon diagnosis were associated with relapse after ATD discontinuation. Future studies are necessary to ascertain the predictors of ATD success in patients with GD.

RESUMEN

Blinatumomab has emerged as a promising component of first-line therapy for acute B-cell precursor lymphoblastic leukemia (BCP-ALL), bolstering treatment efficacy. To mitigate CD19 selection pressure and reduce the incidence of blinatumomab-associated toxicities, pre-treatment chemotherapy is recommended before administering blinatumomab. From September 2022 to December 2023, we conducted a single-arm, multicenter, phase 2 trial (NCT05557110) in newly diagnosed Philadelphia chromosome-negative BCP-ALL (Ph-negative BCP-ALL) patients. Participants received induction treatment with reduced-dose chemotherapy (RDC), comprising idarubicin, vindesine, and dexamethasone over 7 days, followed by 2 weeks of blinatumomab. Those failing to achieve composite complete remission (CRc) received an additional 2 weeks of blinatumomab. The primary endpoint was the CRc rate post initial induction treatment. Of the 35 enrolled patients, 33 (94%) achieved CRc after 2 weeks of blinatumomab, with 30 (86%) achieving measurable residual disease (MRD) negativity. Two patients extended blinatumomab to 4 weeks. With either 2 or 4 weeks of blinatumomab treatment, all patients achieved CR (35/35) and 89% (31/35) were MRD negativity. The median time to CR was 22 days. Immune effector cell-associated neurotoxicity syndrome was limited (14%, all grade 1). Non-hematological adverse events of grade 3 or higher included pneumonia (17%), sepsis (6%), and cytokine release syndrome (9%). With a median follow-up of 11.5 months, estimated 1-year overall survival and 1-year progression-free survival rates were 97.1% and 82.2%, respectively. These findings affirm that RDC followed by blinatumomab is an effective and well-tolerated induction regimen for newly diagnosed Ph-negative BCP-ALL, supporting a shift towards less intensive and more targeted therapeutic approaches.

RESUMEN

BACKGROUND: Numerous studies have compared the efficacy of ustekinumab (UST) and anti-TNF agents [infliximab (IFX) or adalimumab(ADA)] in moderate to severe Crohn's disease (CD) patients. This study aims to compare the efficacy of UST, IFX, and ADA while differentiating between bio-naïve and bio-experienced patients, which is an underexplored aspect, particularly in Asia. METHODS: We conducted a retrospective multi-center study from 2012 to 2023, categorizing patients into bio-naïve and bio-experienced groups. We evaluated clinical remission rates after induction therapy and clinical outcomes, including CD-related hospitalization, intestinal resection, and drug discontinuation during maintenance therapy. RESULTS: Among the 214 bio-naïve CD patients, 60 received UST, 108 received IFX, and 46 received ADA. After 1:1 propensity score matching between UST and anti-TNF agents groups, 59 patients were analyzed in each group (45 in the IFX group and 14 in the ADA group). We found no significant differences in clinical remission rates (P = 0.071), CD-related hospitalization (P = 0.800), intestinal resection (P = 0.390), or drug discontinuation (P = 0.052) between the UST, IFX, and ADA groups in bio-naïve CD patients. In bio-experienced CD patients, with 35 in the UST group and 13 in the anti-TNF agents group, the UST group showed a lower risk of drug discontinuation (P = 0.004) than the anti-TNF agents group. CONCLUSIONS: This study suggests that UST, IFX, and ADA are equally effective in bio-naïve CD patients, while in bio-experienced patients, mostly with previous exposure to anti-TNF agents, UST may offer superior drug durability.

RESUMEN

DNA-hypomethylating agents (HMAs) induce notable remission rates in AML/MDS patients with TP53 mutations; however, secondary resistance often develops rapidly. In the DECIDER trial (NCT00867672), elderly AML patients (also those with adverse genetics) randomized to all-trans retinoic acid (ATRA) added to decitabine (DEC) attained significantly delayed time-to-resistance. An 82-year-old patient with a non-disruptive, in-frame TP53 mutation (p.Cys238_Asn239delinsTyr, VAF 90%) and complex-monosomal karyotype attained a complete hematologic and cytogenetic remission with DEC + ATRA, with 3.7 years survival after 30 treatment cycles that were well-tolerated. Further HMA + ATRA studies appear warranted in AML/MDS patients of different genetic risk groups ineligible for more intensive treatment.Trial registration: This trial was registered at ClinicalTrials.gov identifier: NCT00867672.

RESUMEN

Psossibility and appropriate timing of discontinuation of dupilumab for atopic dermatitis (AD) remain unclear. We explored the possibility of patients, who could maintain remission with topical therapy alone after withdrawing dupilumab in the real world. Furthermore, we identified their characteristics. All adult AD patients who initiated dupilumab from June 2018 to July 2022 and were treated with dupilumab for more than 3 months at our hospital were included in this study. The observation period was from June 2018 to July 2023. In 138 patients, 58 (42.0%) discontinued dupilumab at least once. Among them, 18 (13.0%) discontinued dupilumab but reinitiated dupilumab later due to exacerbation. Only seven patients (5.1%) could maintain remission with topical therapy alone after discontinuation of dupilumab, with characteristics of lower POEM, VAS of pruritus, serum levels of TARC and LDH, and neutrophil counts at baseline, and those of longer duration of dupilumab until its discontinuation (24.0 ± 13.3 vs. 12.8 ± 7.3 months) and lower EASI and affected BSA at the discontinuation of dupilumab. In 118 patients treated with dupilumab for at least 1 year, 38 patients (32.2%) discontinued at least once. Only four patients (3.4%) could maintain remission with topical therapy alone after discontinuation of dupilumab, with characteristics of lower POEM at baseline and lower EASI at the discontinuation of dupilumab. In conclusion, maintaining remission after withdrawing dupilumab is challenging. Discontinuation of dupilumab may be considered in patients with low baseline POEM, after more than 2 years of dupilumab treatment, with a substantial decrease in EASI.

RESUMEN

The therapeutic armamentarium of chronic myeloid leukemia (CML) has dramatically improved after small molecule tyrosine kinase inhibitors (TKIs) targeting BCR::ABL1 became available, with a life expectancy now close to that of the general population. Although highly effective, these drugs also have a toxicity profile that is often mild to moderate, but sometimes severe. Indeed, long-term treatment with TKIs can lead to chronic adverse events that can negatively affect patients' quality of life and can promote significant morbidity and mortality, particularly in the case of second- or third-generation TKIs. Treatment discontinuation has therefore become an emerging goal for CML patients and numerous studies have evaluated in off-TKI subjects what requirements are appropriate for an attempt at treatment-free remission (TFR). TFR eligibility is currently limited to a small population of subjects with both deep and sustained molecular responses to TKIs. For those attempting TFR, average success rates are promising, with 25%-30% of patients experiencing prolonged TFR. In case of failure to maintain sustained TFR, safety results to date are reassuring, with almost all patients responding successfully to resumption of TKIs, and advanced-phase disease progression representing a very rare event. The purpose of this review is to discuss guidelines for TKI discontinuation, clinical advances from clinical trials and real-life experiences, and describe areas of research, particularly regarding the biological factors capable of predicting the success of TFR.

RESUMEN

Mild psoriasis may be burdensome; if symptoms are inadequately controlled, switching therapy may be warranted. In the Phase 3 NAVIGATE trial, patients with moderate-to-severe plaque psoriasis received ustekinumab for 16 weeks. Patients with inadequate response (Investigator's Global Assessment [IGA] ≥ 2) were randomized to switch to guselkumab or continue ustekinumab. This post-hoc analysis evaluated the patient subgroup with residual mild psoriasis (IGA = 2) after initial ustekinumab therapy. Outcomes assessed included the Psoriasis Area and Severity Index (PASI), Dermatology Life Quality Index (DLQI), and Psoriasis Symptoms and Signs Diary (PSSD). Initially, 871 patients received ustekinumab. At Week 16, 161 randomized patients had residual mild psoriasis (IGA = 2). Among guselkumab- vs ustekinumab-treated patients at Week 28, 59.0% vs 27.7% achieved PASI 90, and 50.0% vs 21.0% achieved DLQI 0/1. Mean changes from baseline in PSSD score were -44 vs -28 and -50 vs -32, respectively, with thresholds of -40 considered clinically meaningful. Mean changes in PSSD itch score were -4.6 vs -2.9, with reductions ≥ 4.0 considered clinically meaningful. Treatment differences were maintained/increased through Week 52. Among patients with residual mild psoriasis after 16 weeks of ustekinumab, those switching to guselkumab had greater improvements in skin clearance, health-related quality of life, and patient-reported symptoms and signs than those continuing ustekinumab.

RESUMEN

Despite the abundance of data concerning biologic treatments for patients with psoriasis, clinicians are often challenged with discerning the optimal treatment for each patient. To inform this selection, this study explored whether a patient's baseline characteristics or disease profile could predict the likelihood of achieving complete skin clearance with biologic treatment. Machine-learning and other statistical methods were applied to the substantial data collected from patients with moderate-to-severe psoriasis in the ongoing, international, prospective, observational Psoriasis Study of Health Outcomes (PSoHO). The 3 measures of complete skin clearance were a psoriasis area and severity index (PASI)100 response at (a) week 12, (b) month 12, and (c) week 12 and maintain ed at month 6 and month 12 (PASI100 durability). From these real-world data, the absence of nail psoriasis emerged  as the most consistent feature that may be used by clinicians to predict high-level treatment responses with biologic treatment. Other significant predictors of skin clearance with biologic treatments were the absence of hypertension and a lower body surface area affected by psoriasis. Overall, this study evidences the substantial challenge of identifying reliable clinical markers of treatment response for patients with psoriasis and highlights the importance of regular screening for psoriatic nail involvement.

RESUMEN

INTRODUCTION: Although there are well-defined guidelines for the management of mild-to-moderate ulcerative colitis (UC), there are still unmet needs. For this reason, we conducted an international expert consensus to standardize the management of patients with mild-to-moderate UC and provide practical guidance to clinicians. AREAS COVERED: Based on Delphi methodology, 15 statements were approved after two rounds of voting, addressing several aspects of disease management from sequencing to treatment duration, from monitoring to optimization techniques and safety profile. EXPERT OPINION: Growing knowledge of mild-to-moderate UC has led to the development of new ambitious outcomes such as histological remission and disease clearance. Furthermore, noninvasive tools for patient monitoring such as fecal calprotectin and intestinal ultrasound are now available. Their implementation in clinical practice will allow clinicians to tightly monitor disease activity and promptly adapt treatment, avoiding complications and disease progression and targeting better disease control.

RESUMEN

BACKGROUND: During the run-in phase of the TESTING study, approximately half of patients with IgA nephropathy (IgAN) were excluded due to proteinuria below 1 g/24 h after intensive supportive therapy. The long-term prognosis of these patients needs further investigation. METHODS: 112 screening failed patients in the TESTING study from 10 centers in China were enrolled in this retrospective study. The prognosis of 88 patients, who were excluded because of proteinuria below 1 g/24 h, was analyzed by Landmark Kaplan-Meier analysis. The composite kidney endpoint was defined by a ≥ 50% reduction in eGFR, ESKD (eGFR <15 mL/min per 1.73 m2), chronic dialysis for at least 6 months, or renal transplantation. RESULTS: In total, 88 patients were excluded due to proteinuria less than 1 g/24 h. During the follow-up, 73/88 (83.0%) patients received renin-angiotensin system blocker. 72/88 (81.8%) had stable proteinuria remission and did not receive immunosuppressive therapy (IST), and 16/88 (18.2%) received IST because of a relapse of proteinuria. Landmark Kaplan-Meier analysis revealed that, the kidney survival from dialysis or composite kidney outcome of these excluded patients with IST was similar to those without IST during the early stages of follow-up (dialysis, before 60 months, p = 0.778; composite kidney outcome, before 48 months, p = 0.862); whereas the risk for dialysis of patients receiving IST was significantly higher than those without IST after 60 months (OR = 11.3, p = 0.03). Similarly, the risk for the composite kidney outcome of patients receiving IST was also significantly higher than those without IST after 48 months (OR = 5.92, p = 0.029). CONCLUSIONS: IgAN patients who maintained a persistent remission of proteinuria after intensive supportive therapy had a much better long-term kidney outcome than those who experienced a relapse of proteinuria and needed IST.

RESUMEN

The utility of Rituximab (RTX) for IgA vasculitis nephritis (IgAVN) is not well established. Up to now, we analysed the largest samples of IgAVN patients treated by RTX with a total of 41 retrieved subjects up to December 29, 2023 in the present systematic review. We assessed the clinical profiles, efficacy, and safety of RTX treatments. The present review showed that the renal function tended to be stabilized (P = 1.000) and urinalysis tended to normalize after RTX treatment with no serious adverse events reported. Moreover, 40% (16/40) of patients was freed use of glucocorticoid after RTX administration (P < 0.001). The remission rate was 92.7% (38/41) and complete remission rate was 46.3% (19/41) in IgAVN patients. Interestingly, 76.9% (10/13) of IgAVN child patients achieved complete remission when compared with 32.1% (9/28) of adult patients (P = 0.017). In summary, our results support the benefit of RTX therapy in IgAVN patients, especially children subjects.

RESUMEN

OBJECTIVES: To assess the ability of baseline serum biomarkers to predict disease activity and remission status in juvenile idiopathic arthritis (JIA) at 18-year follow-up (FU) in a population-based setting. METHODS: Clinical data and serum levels of inflammatory biomarkers were assessed in the longitudinal population-based Nordic JIA cohort study at baseline and at 18-year FU. A panel of 16 inflammatory biomarkers was determined by multiplexed bead array assay. We estimated both univariate and multivariate logistic regression models on binary outcomes of disease activity and remission with baseline variables as explanatory variables. RESULTS: Out of 349 patients eligible for the Nordic JIA cohort study, 236 (68%) had available serum samples at baseline. We measured significantly higher serum levels of interleukin 1ß (IL-1ß), IL-6, IL-12p70, IL-13, MMP-3, S100A9 and S100A12 at baseline in patients with active disease at 18-year FU than in patients with inactive disease. Computing receiver operating characteristics illustrating the area under the curve (AUC), we compared a conventional prediction model (gender, age, joint counts, erythrocyte sedimentation rate, C reactive protein) with an extended model that also incorporated the 16 baseline biomarkers. Biomarker addition significantly improved the ability of the model to predict activity/inactivity at the 18-year FU, as evidenced by an increase in the AUC from 0.59 to 0.80 (p=0.02). Multiple regression analysis revealed that S100A9 was the strongest predictor of inactive disease 18 years after disease onset. CONCLUSION: Biomarkers indicating inflammation at baseline have the potential to improve evaluation of disease activity and prediction of long-term outcomes.

BACKGROUND: We report the final results of treatment with aripiprazole, blonanserin, and paliperidone from the Japan Useful Medication Program for Schizophrenia (JUMPs), a 104-week naturalistic study. METHODS: JUMPs was an open-label, three-arm, randomized, parallel-group, 104-week study. Patients aged ≥ 20 years with schizophrenia requiring antipsychotic treatment or a switch from previous therapy were enrolled. The primary endpoint was treatment discontinuation rate over 104 weeks. Secondary endpoints included remission rate, Personal and Social Performance (PSP), safety, Positive and Negative Syndrome Scale (PANSS), and quality of life (QOL; EuroQol-5 dimension). RESULTS: In total, 251 patients received aripiprazole (n = 82), blonanserin (n = 85), or paliperidone (n = 84). Treatment discontinuation rates (aripiprazole, 80.5%; blonanserin, 81.2%; paliperidone, 71.4%) were not significantly different (p = 0.2385) among the treatment groups at 104 weeks; comparable outcomes were observed for endpoints, including remission (42.9%, 46.7%, and 45.8%), PANSS, and safety. In the overall cohort, while the improvement in the PSP total score at Week 104 was not significantly different from baseline, a significant improvement (p < 0.05) in QOL and total PANSS scores (including all subscales) was observed at Week 104 compared with baseline. Multivariable analysis identified a shorter disease duration and a higher chlorpromazine-equivalent antipsychotic dosage level (≥ 1000 mg) before switching to monotherapy as predictors of treatment discontinuation. CONCLUSIONS: The 104-week treatment outcomes were comparable between groups; the overall trend of improvement in remission rate, safety, and QOL suggests the importance of continued treatment. CLINICAL TRIAL REGISTRATION: UMIN-Clinical Trials Registry UMIN000007942 (public release date: 14/05/2012).

RESUMEN

Objective: To explore the prognostic factors of primary plasma cell leukemia (pPCL) in the era of novel agents. Methods: The clinical data of 66 patients with pPCL treated at the Department of Haematology, Beijing Chao-Yang Hospital, Capital Medical University from 2011 to 2022 were retrospectively collected to analyze their prognostic factors. Results: Among the 66 patients with pPCL, the median age was 59 (range: 29-79) years. The median overall survival (OS) duration was 19.0 (95% CI 10.4-27.6) months, and the median progression-free survival (PFS) duration was 11.0 (95% CI 6.5-15.6) months. The median OS and PFS were significantly longer in patients with the best post-treatment response of very good partial remission (VGPR) or better than in patients with a response of partial remission (PR) or worse (median OS: 33.0 months vs 6.0 months, P<0.001; median PFS: 16.0 months vs 3.0 months, P<0.001). OS was significantly longer in patients who underwent autologous hematopoietic stem cell transplantation than in those who did not undergo transplantation (49.0 months vs 6.0 months, P=0.002), and there was a trend toward a longer PFS in patients who underwent transplantation than in those who did not undergo transplantation (19.0 months vs 8.0 months, P=0.299). The median OS and PFS were significantly longer in patients who received maintenance therapy than in those who did not receive maintenance therapy (median OS: 56.0 months vs 4.0 months, P<0.001; median PFS: 20.0 months vs 2.0 months, P<0.001). Multivariate analysis showed that hypercalcemia was an independent risk factor (HR=3.204, 95% CI 1.068-9.610, P=0.038) for patients with pPCL, while receiving maintenance therapy (HR=0.075, 95% CI 0.022-0.253, P<0.001) and post-treatment response of VGPR or better (HR=0.175, 95% CI 0.048-0.638, P=0.008) were independent protective factors for patients with pPCL. Conclusions: In the era of novel agents, hypercalcemia, receiving maintenance therapy, and post-treatment response of VGPR or better are independent prognostic factors for pPCL.
