The association between serum complement 4 and relapse of primary membranous nephropathy: a multicenter retrospective cohort study

BackgroundRelapse after initial remission reduces renal survival in patients with primary membranous nephropathy (PMN). In this study, we aim to identify risk factors of relapse in PMN and construct a model to identify patients at high risk of relapse early.MethodsWe conducted a multi-center retrospective study using the China Renal Data System database, which includes data from 24 urban academic centers across China. A prediction model based on the Cox proportional hazards model was derived in the derivation group and validated in the validation group.Result515 patients with biopsy-proven PMN achieving initial remission were enrolled. 32.62% of patients subsequently relapsed during a median of 6.08 months. Lower serum albumin (Alb) (per 1 g/L decrease, hazard ratio [HR] =1.48, 95% confidence interval [CI] 1.29–1.78, p < 0.001), lower estimated glomerular filtration rate (eGFR) (per 10 mL/min/1.73m2 decrease, HR =1.14, 95% CI 0.97–1.49, p < 0.001), higher serum complement 4 (C4) (per 0.1 g/L increase, HR =1.89, 95% CI 1.32–3.22, p = 0.012), partial remission (PR) (HR =2.28, 95%CI 1.74–4.04, p < 0.001), and treatment with calcineurin inhibitors (CINs) (HR =1.33, 95%CI 1.04–1.64, p < 0.001) at the time of remission were risk factors for relapse. C-statistic, time-dependent areas under the receiver operating characteristic curve, and calibration plots confirmed that the model had excellent discrimination and calibration in predicting PMN relapse. The anti-phospholipase A2 receptor antibody (aPLA2Rab) titers and pathologic features did not substantially improve the model.ConclusionOur study confirms the well-known low Alb and eGFR, PR, and treatment of CNIs at the time of remission as risk factors for PMN relapse, but aPLA2Rab and pathologic features may not predict relapse. In addition, it is the first study to show serum C4 is associated with PMN relapse. We suggest that complement-targeted therapies may be a potential therapy to prevent PMN relapse.

Analysis of clinical characteristics and risk factors for recurrence of combined EB virus infection in patients with inflammatory bowel disease treated with biological agents

To investigate the degrees of EB virus reactivation in patients with inflammatory bowel disease (IBD) treated with different biologics and the levels of important cytokines associated with relapse under the influence of this virus, and to assess its diagnostic efficacy as a risk factor for identifying disease relapse. A case-control retrospective study based on patients' hospitalization history data was conducted to select a total of 105 patients who were hospitalized in the Department of Gastroenterology, Huashan Hospital, Fudan University, with a confirmed diagnosis of IBD from 2021 to 2023. Based on the quantitative copy level of whole blood EBV DNA to determine the status of EB virus infection in patients, integrated cytokine 8 (IL-2, IL-4, IL-6, IL-10, IL-12p70, IL-17, TNF-α, IFN-γ), C-reactive protein, and fecal calreticulin, to find the risk variable associated with treatment relapse. Logistic regression was used to analyze the relative risk between this variable and treatment relapse, and ROC curves were used to predict the diagnostic efficacy of cytokine multifactorial thresholds for treatment relapse. Results showed that the median age of the study was 37(26, 54)years, with a minimum of 18 years and a maximum of 70 years, with a median age of 34(24, 51) years for Crohn's Disease (CD) patients and 46(35, 60) years for Ulcerative colitis (UC) patients, with a statistically difference between the ages of the two groups (t=2.675, P=0.009). The median age at 50 years of patients treated with Vedolizumab (VDZ) in the UC group was higher than in the treatment groups other than VDZ. The highest rate of EB virusreactivation was found in the group treated with immunosuppressants Azathioprine (AZA) combined with anti-tumor necrosis factor-α (anti-TNF-α) and VDZ (62.5% in both groups), and the lowest in the group treated with Ustekinumab (UST) (0%). IL-2 levels were elevated in the AZA+anti-TNF-α and anti-TNF-α groups after EB virus entryreactivation. Three treatment groups, AZA+anti-TNF-α, anti-TNF-α, and VDZ, had elevated levels of IL-6 expression after EB virus entry reactivation.In the anti-TNF-α treatment-related group IL-2was associated with treatment relapse in IBD (OR=1.127, 95%CI: 1.044-1.256, P=0.007). ROC analysis showed that the AUC for IL-2 combined with EB virus in a replicative state was 0.8282 (P=0.006), with a negative predictive value and a positive value of 90% and 75%, respectively. As well as IL-6 was associated with treatment relapse of IBD in the anti-TNF-αtreatment-related group as well as in the VDZ-treated group (OR=1.049, 95%CI: 1.017-1.095, P=0.008). ROC analysis showed that the diagnostic sensitivity and specificity for post-treatment relapse at a critical value of 6.10 pg/ml for IL-6 was 83.33% and 82.93%, respectively. The AUC for IL-6 combined with EB virus in a replicative state was 0.900 (P<0.000 1), with negative and positive predictive value of 84.09% and 73.33%, respectively. In summary, the imbalance of proinflammatory and anti-inflammatory cytokines varies between drugs, with EBV in a replication-activated state, combined with elevated levels of IL-2 as well as IL-6 expression being a risk factor for relapse in patients treated with anti-TNF-α-related drugs and VDZ.

Enhancing outcomes of childhood acute lymphoblastic leukemia in workplace diversity in Thailand: multicenter study on behalf of the Thai Pediatric Oncology Group.

The Thai Pediatric Oncology Group (ThaiPOG) has adapted treatment regimens from the Children's Oncology Group (COG) to enhance outcomes for childhood acute lymphoblastic leukemia (ALL). This study examined the risk factors and treatment results of pediatric ALL in Thailand. This multicenter study included newly diagnosed children (< 18years) with ALL in 19 centers between January 1, 2015, and December 31, 2019. Most of the 1,157 patients (97.6%) were treated according to ThaiPOG protocols. The genetic testing was performed in 71% of patients. The patients were classified as standard (n = 539), high (n = 402), and very high (n = 130) risks. The 5-year event-free survival (EFS) and overall survival (OS) rates were 75% (95% confidence intervals (CI), 72%-77.8%) and 81.7% (95% CI, 78.9%-84.1%), respectively. The 5-year EFS rates of the standard-, high-, and very high-risk groups were 78.5% (95% CI, 74.1%-82.3%), 73.6% (95% CI, 68.5%-78%) (p = 0.761), and 65% (95% CI, 55.1%-73.3%) (p = 0.001), respectively, and the 5-year OS rates were 86.9% (95% CI, 83.1%-89.9%), 77.3% (95% CI, 72.5%-81.4%) (p = 0.001), and 73.1% (95% CI, 63.7%-80.4%) (p = 0.001), respectively. The independent risk factors for relapse and death were age ≥ 10years, white blood cells (WBCs) ≥ 50,000/mm3, M2 or M3 marrow status at the end of induction, and high-risk group. The overall outcome of Thai pediatric ALL has improved after the implementation of new modified COG treatment protocols. High-risk characteristics of ALL increased adverse outcome risk.

Relapse risk factors and clinical characteristics of idiopathic inflammatory myopathies in 105 patients.

To identify the risk factors for relapse of idiopathic inflammatory myopathies (IIMs). Patients who were newly diagnosed with IIMs and underwent muscle biopsy between 2000 and 2017 at Asan Medical Center were retrospectively reviewed. The relapse of IIMs was defined as the recurrence of muscle or cutaneous manifestations with a ≥50% increase in glucocorticoid dosage after reaching the low-dose glucocorticoid phase with clinically significant improvement. The factors associated with the relapse of IIMs were investigated by Cox proportional hazards analysis. Of 105 patients with IIMs, relapse was observed in 65 patients (62%). The titer of antinuclear antibody (ANA) was higher in the relapse group than in the non-relapse group (P = 0.033). Multivariable analysis showed that the relapse of IIMs was significantly associated with histopathologic features consistent with IIMs (hazard ratio [HR], 1.69; 95% confidence interval [CI], 1.01-2.83, P = 0.045) and the use of immunosuppressants before relapse (HR, 0.50; 95% CI, 0.29-0.86, P = 0.013). Doubling of ANA titer was also associated with relapse, albeit without statistical significance (HR, 1.13; 95% CI, 1.00-1.27, P = 0.052). In patients with IIMs, the use of immunosuppressants had a significant negative association with relapse. Administering immunosuppressants from the early period during the initial glucocorticoid tapering phase may be useful in reducing the risk of relapse in patients with IIMs. Key Points • Since idiopathic inflammatory myopathies (IIMs) have a low prevalence, it is poorly understood which factors are associated with the relapse of IIMs. • In this study, about two-thirds of 105 patients with IIMs experienced a relapse of IIMs. • The risk of relapse in patients with IIMs was negatively associated with the use of immunosuppressants during glucocorticoid tapering and low-dose glucocorticoid phase. • Even in less severe cases, the use of immunosuppressants might be a good option for the management of IIMs.

Pemphigus relapse: Mechanisms, risk factors, and agents associated with disease recurrence.

Pemphigus represents a spectrum of potentially life-threatening autoimmune-mediated skin blistering conditions caused by antibody production against desmoglein 1 and 3 (anti-DSG 1 and 3) in keratinocytes. Greater than 50% of pemphigus patients experience relapse, which complicates long-term medical management, including risks associated with re-treatment and complications such as infection and dehydration. This review aims to elucidate mechanisms, risk factors, and medications associated with pemphigus relapse. Mechanisms of relapse include the persistence of auto-reactive B-cell populations post-treatment and CD20- B-cell populations that reactivate after B-cell depletion therapy. Risk factors for relapse include high body surface area (BSA) of pemphigus involvement, high body mass index, high severity according to the Pemphigus Disease Area Index (PDAI) at onset, treatment delay, and high anti-DSG1 and DSG3 titers post-treatment. Targeted B-cell localization is associated with better clinical outcomes, including less frequent relapses. Rituximab is currently the gold standard of treatment for moderate-severe pemphigus and has relapse rates of 11%-44% in selected studies, with a mean time to relapse of 5.8 months to 36 months following treatment. Relapse rates across lymphoma dosing (375 mg/m2) versus rheumatoid arthritis dosing (1 g dosing weekly) was inconsistent; however, more frequent dosing, earlier treatment, and higher cumulative dosing were associated with lower relapse rates. Alternative agents that have clinical efficacy include corticosteroid monotherapy, mycophenolate mofetil, azathioprine, and intravenous immunoglobulin. Future studies should include head-to-head comparators over long follow-up periods to identify the best treatment agents associated with the least relapse risk.

Elevations in interleukin-8 levels in individuals with alcohol use disorder and clinical insomnia symptoms.

Insomnia commonly co-occurs with alcohol use disorder (AUD) and predicts poorer outcomes for those with AUD. Insomnia and AUD are individually associated with increases in systemic inflammation. Insomnia and inflammation both serve as risk factors for relapse in AUD. However, little is known about the relationship between insomnia and systemic inflammation in individuals with AUD. Therefore, the present study examined the relationship between the severity of insomnia symptoms and plasma levels of inflammatory cytokines in a sample of treatment-seeking individuals with an AUD. This secondary analysis included 101 (61M/40F) individuals with an AUD. Participants were categorized into groups based on their scores on the Insomnia Severity Index: no insomnia (n = 47), subthreshold insomnia (n = 37), and clinical insomnia (n = 17). Participants provided blood samples to measure plasma levels of four peripheral markers of inflammation (IL-6, IL-8, TNF-α, and CRP). Inflammatory marker levels were compared between groups. Interactive effects of sex and AUD severity were examined. There was a significant main effect of insomnia group on log IL-8 levels (F = 6.52, p = 0.002), such that individuals with AUD and clinical insomnia had higher log IL-8 levels compared to both the no insomnia and subthreshold insomnia groups (ps ≤ 0.05). Sex and AUD severity interacted with this relationship, such that men with clinical insomnia and AUD and individuals with severe AUD had higher log IL-8 levels. There were no significant effects of insomnia on IL-6, TNF-α, or CRP levels. The present study identified a specific elevation in IL-8 levels in individuals with an AUD and clinical insomnia that was not identified in other markers of peripheral inflammation (IL-6, TNF-α, CRP). Sex and AUD severity interacted with insomnia symptoms, indicating that those with clinical insomnia and severe AUD or male sex may be the most vulnerable to the inflammatory consequences associated with AUD and clinical insomnia symptoms.

Risk factors for relapse of immune-related pneumonitis after 6-week oral prednisolone therapy: a follow-up analysis of a phase II study.

Immune-related pneumonitis (irP) is one of the most important immune-related adverse events caused by immune checkpoint inhibitors (ICIs). After corticosteroid therapy irP frequently relapses, which can interfere with cancer therapy. However, risk factors for irP relapse are unknown. This study was a follow-up analysis of a phase II study that evaluated 56 patients with grade ≥ 2 irP treated with oral prednisolone, 1mg/kg/day, tapered over 6 weeks. Clinical factors including patient characteristics, blood test findings, and response to prednisolone therapy were assessed to identify risk factors for irP relapse using the Fine-Gray test. Among 56 patients with irP, 22 (39.3%) experienced irP relapse after 6 weeks of prednisolone therapy during the follow-up observation period. Radiographic organising pneumonia (OP) pattern and duration to irP onset ≥ 100 days from ICI initiation were determined to be significant risk factors for irP relapse in a multivariate Fine-Gray test (hazard ratio [HR] = 3.17, 95% CI 1.37-7.32, p = 0.007, and HR = 2.61, 95% CI 1.01-6.74, p = 0.048, respectively). Other patient characteristics, blood test findings, irP severity, and response to prednisolone therapy were not associated with irP relapse. In irP patients treated with 6-week prednisolone tapering therapy, OP pattern and duration to irP onset ≥ 100 days were associated with relapse risk. Assessment of the risk factors for irP relapse will be helpful for irP management.

Risk Factors of Relapse in Nephrotic Syndrome

Background: Nephrotic syndrome (NS) is a kidney disease with high incidence, typically in young children. NS is a disease of relapse, and it is a major problem to manage the cases with relapse. So, it is very important to find out such children who are prone to develop relapse. Hence, this study was carried out to find out the risk factors of relapse in children with NS. Objective: To determine the risk factors of relapse in patients with nephrotic syndrome. Methods: This case-control study was conducted at the Department of Paediatric Nephrology and Department of Paediatrics, Dhaka Medical College Hospital, for 12- months following ethical approval. A total of 100 NS children (age: 2-12 years) were enrolled in this study, among them 50 were cases (NS with relapse) and 50 were controls (initial attack of NS with no relapse within one year of disease onset). After obtaining written informed consent from parents/legal guardian, a detailed history, thorough clinical examination and necessary investigations were carried out in each patient during initial episode of NS. Data analysis was done by SPSS 26.0. Results: Mean age of the cases and controls was6.11±3.01years and 6.96±3.14years, respectively (p=0.169), with an overall boys-girl ration of 1.3:1. Maximum cases (56.0%) had infrequent relapse. Lower age of onset was prevalent among case group than control (31.96±15.15 months vs 46.48±27.76 months; p=0.002). Infection was significantly more prevalent among cases than controls (68.0% vs 38.0%; OR=3.46; p=0.003), UTI (38.0% vs 10.0%; OR; 5.52; p=0.001). Cases had significantly higher history of atopy (52.0% vs 30.0%; OR=2.53; p=0.025). Higher serum cholesterol (441.62±61.46 mg/dL vs 389.12±72.18 mg/dL; &lt;0.001) and lower serum albumin (15.74±2.20 gm/L vs 17.30±2.99 gm/L; p=0.004) were seen in cases than control. Conclusion: Lower age of onset, history of atopy, infection, higher serum cholesterol and lower serum albumin level during initial attack were associated .......

Assessing the Risk of Tuberculosis Relapse Development during the Period of Stabilization of the COVID-19 Epidemic

The objective: to evaluate risk factors for tuberculosis relapse development during stabilization of the COVID-19 situation.Subjects and Methods. 165 patients over 18 years of age were enrolled in the observational comparative study, those patients were followed up due to respiratory tuberculosis relapses in 2021-2023. Risk factors for early and late relapses that occurred during the pandemic (2021-2022) and post-pandemic (2023) periods were analyzed. They included age, gender, accommodation, social status, imprisonment, smoking, alcohol and substances abuse, comorbidities, clinical forms of tuberculosis, presence of cavities, bacterial excretion, and drug resistance of Mycobacterium tuberculosis.Results. The data obtained confirmed the assumption that the COVID-19 pandemic had led to changes in social and medical-biological risk factors for tuberculosis relapse.

Risk Factors for Locoregional Relapse After Segmentectomy: Supplementary Analysis of the JCOG0802/WJOG4607L Trial

IntroductionThe JCOG0802/WJOG4607L trial revealed superior overall survival in segmentectomy compared with lobectomy for small-peripheral NSCLC. Nevertheless, locoregional relapse (LR) is a major issue for segmentectomy. An ad hoc supplementary analysis aimed to determine the risk factors for LR and the degree of advantages of segmentectomy on the basis of primary tumor sites. MethodsParticipants in multi-institutional and intergroup, open-label, phase 3 randomized controlled trial in Japan were enrolled from August 10, 2009, to October 21, 2014. Risk factors for LR after segmentectomy and clinical features following the primary tumor site were investigated. ResultsOf 1105 patients, 576 and 529 underwent lobectomy and segmentectomy, respectively. The primary tumor site for segmentectomy was the left upper division, left lingular segment, left S6, left basal segment, right upper lobe, right S6, or right basal segment. Multivariable analysis in the segmentectomy group revealed that pure-solid appearance on thin-section computed tomography (OR = 3.230; 95% confidence interval [CI]: 1.559–6.690; p = 0.0016), margin distance less than the tumor size (OR = 2.682; 95% CI: 1.350–5.331; p = 0.0049), and male sex (OR = 2.089; 95% CI: 1.047–4.169; p = 0.0366) were significantly associated with LR. Patients with left lingular segment tumors (OR = 4.815; 95% CI: 1.580–14.672) tended to experience LR more frequently than those with left upper division tumors, although primary tumor sites were not statistically significant. ConclusionsThin-section computed tomography findings and margin distance are important factors to avoid LR in segmentectomy.

Pre-transplantation levels of lysine (K)-specific methyltransferase 2A (KMT2A) partial tandem duplications can predict relapse of acute myeloid leukemia patients following haploidentical donor hematopoietic stem cell transplantation.

We aimed to identify dynamic changes of lysine (K)-specific methyltransferase 2A partial tandem duplications (KMT2A-PTD) before and after haploidentical donor hematopoietic stem cell transplantation (HID HSCT) and explore the prognostic value of pre-transplantation levels of KMT2A-PTD in acute myeloid leukemia (AML) receiving HID HSCT. Consecutive 64 AML patients with KMT2A-PTD positivity at diagnosis receiving HID HSCT were included in this study. Patients with KMT2A-PTD ≥1% before HSCT had a slower decrease of KMT2A-PTD after HID HSCT. Patients with KMT2A-PTD ≥1% before HID HSCT had a higher cumulative incidence of relapse (36.4%, 95% confidence interval [CI]: 6.3%-66.5%) at 2 years after HSCT than those with KMT2A-PTD <1% (7.5%, 95% CI: 0.3%-14.7%, P = .010). In multivariable analysis, KMT2A-PTD ≥1% before HID HSCT was the only independent risk factor for relapse (hazard ratio [HR]: 4.90; 95% CI: 1.22-19.59; P = .025). Thus, pre-transplantation levels of KMT2A-PTD could predict relapse in AML patients following HID HSCT.

Long-Term Survival and Immune Reconstitution of Donor-Derived Chimeric Antigen Receptor T-Cell Therapy for Childhood Molecular Relapse of B-Cell Acute Lymphoblastic Leukemia After Allogeneic Hematopoietic Stem Cell Transplantation

Measurable residual disease (MRD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an independent risk factor for relapse in patients with acute lymphoblastic leukemia (ALL). This study aimed to assess the efficacy, safety, and immune reconstitution of chimeric antigen receptor T-cell (CAR-T) therapy in patients with molecular relapse after allo-HSCT. Eleven patients with molecular relapse of B-cell-ALL who underwent CAR-T therapy after allo-HSCT were enrolled. The rate of MRD negativity after a month of CAR-T infusion was 81.8%. Patients who bridged to second-HSCT after CAR-T therapy (n = 3) showed a trend of higher 3-year leukemia-free survival and 3-year overall survival than those who did not (n = 8; 100% vs. 75.0%; 95% CI, 45.0–104.9%; p = 0.370). No treatment-related mortalities were observed. Among patients who did not bridge to second-HSCT and remained in complete remission until the last follow-up (n = 6), five of them had not recovered normal immunoglobulin concentrations with a median follow-up of 43 months. CAR-T therapy may be a safe and effective treatment strategy to improve survival after allo-HSCT; however, the problem of prolonged hypogammaglobulinemia in patients who do not bridge to second-HSCT is worth noting.

Follow-up strategies after trimodal treatment for muscle-invasive bladder cancer: a systematic review

PurposeOptimal follow-up strategies following trimodal treatment for muscle invasive bladder cancer play a crucial role in detecting and managing relapse and side-effects. This article provides a comprehensive summary of the patterns and risk factors of relapse, functional outcomes, and follow-up protocols.MethodsA systematic literature search on PubMed and review of current guidelines and institutional follow-up protocols after trimodal therapy were conducted.ResultsOut of 200 identified publications, 43 studies (28 retrospective, 15 prospective) were selected, encompassing 7447 patients (study sizes from 24 to 728 patients). Recurrence rates in the urinary bladder varied between 14–52%; 3–16% were muscle-invasive while 11–36% were non-muscle invasive. Nodal recurrence occurred at 13–16% and distant metastases at 15–35%. After 5 and 10 years of follow-up, around 60–85% and 45–75% of patients could preserve their bladder, respectively. Various prognostic risk factors associated with relapse and inferior survival were proposed, including higher disease stage (> c/pT2), presence of extensive/multifocal carcinoma in situ (CIS), hydronephrosis, multifocality, histological subtypes, incomplete transurethral resection of bladder tumor (TURBT) and incomplete response to radio-chemotherapy. The analyzed follow-up guidelines varied slightly in terms of the number, timing, and types of investigations, but overall, the recommendations were similar.ConclusionRandomized prospective studies should focus on evaluating the impact of specific follow-up protocols on oncological and functional outcomes following trimodal treatment for muscle-invasive bladder cancer. It is crucial to evaluate personalized adaption of follow-up protocols based on established risk factors, as there is potential for improved patient outcomes and resource allocation.

Molecular profiling of risk factors for relapse in Japanese patients with stage II colorectal cancer: a retrospective cohort study.

The association between the molecular profiles and prognosis of Stage II colorectal cancer remains unclear. This study aimed to examine the risk factors for relapse of Stage II colorectal cancer using molecular profiling. We retrospectively enrolled patients with pStage II colorectal cancer who did not receive perioperative adjuvant therapy and whose surgically resected specimens were evaluated using gene expression and whole-exome analyses between January 2014 and December 2018. We evaluated the long-term outcomes and examined the risk factors for relapse-free survival. We evaluated 322 patients with pStage II colorectal cancer, including 126 (39.1%) with right colon cancer. Eighty-seven patients (27.0%) had pT4 tumor, 175 (54.3%) had positive venous invasion, 120 (37.3%) had positive lymphatic invasion, and 68 (21.1%) had perineural invasion. The presence of mutations in key genes for colorectal cancer development based on whole-exome analyses was as follows: APC, 245 (76.1%); TP53, 208 (64.6%); and KRAS, 134 (41.6%). According to the consensus molecular subtype classification based on gene expression, 76 patients (23.6%) had consensus molecular subtype 4 and a significantly lower relapse-free survival than the other patients (5-year relapse-free survival: 83.8% vs. 92.9%, p = 0.017). Perineural invasion (hazard ratio: 5.316, p < 0.001) and consensus molecular subtype 4 (hazard ratio: 2.399, p = 0.020) were identified as independent risk factors for relapse-free survival. Molecular profiling of Stage II colorectal cancer to assess the risk factors for relapse may contribute to the indication and drug selection for adjuvant chemotherapy.

Identifying risk factors for relapse in graves' disease: a retrospective study

Identifying risk factors for relapse in graves' disease: a retrospective study

Clinical characteristics of double negative atypical inflammatory demyelinating disease: A prospective study.

This study aimed to investigate the clinical characteristics and predictors of relapse in double negative atypical inflammatory demyelinating disease (IDD) and to explore potential antigenic targets by tissue-based assays (TBA) using rat brain indirect immunofluorescence. We compared the clinical, laboratory, and MRI data of double negative atypical IDD with other IDD patients. Serum samples were collected for TBA. The predictors of relapse were examined over a minimum of 24 months follow-up. In our cohort of 98 patients with double negative atypical IDD, there was no significant female predominance (58.2%, 57/98). The lesions primarily affected the spinal cord and brain stem, with fewer cases of involvement in the area postrema (5.1%, 5/98) and longitudinally extensive transverse myelitis (43.9%, 43/98). A total of 62.5% (50/80) patients tested positive for anti-astrocyte antibodies based on rat brain TBA. Over a median duration of 39.5 months, 80 patients completed the entire follow-up, and 47.5% (38/80) patients exhibited monophasic course. A total of 36% (18/50) patients positively for anti-astrocyte antibodies had a monophasic course, which is significantly lower than patients negatively for anti-astrocyte antibodies (66.7%, 20/30) (p = 0.008). The presence of anti-astrocyte antibodies (hazard ratio (HR), 2.243; 95% CI, 1.087-4.627; p = 0.029) and ≥4 cerebrum lesions at first attack (HR, 2.494; 95% CI, 1.224-5.078; p = 0.012) were risk factors for disease relapse, while maintenance immunotherapy during remission (HR, 0.361; 95% CI, 0.150-0.869; p = 0.023) was protective factor. Double negative atypical IDD are unique demyelinating diseases with a high relapse rate. Maintenance immunotherapy is helpful to the prevention of relapse, particularly in patients with anti-astrocyte antibodies or ≥4 cerebrum lesions at first attack.

Development and validation of a nomogram for predicting rapid relapse in triple-negative breast cancer patients treated with neoadjuvant chemotherapy.

Triple-negative breast cancer (TNBC) accounts for disproportionately poor outcomes in breast cancer, driven by a subset of rapid-relapse TNBC (rrTNBC) with marked chemoresistance, rapid metastatic spread, and poor survival. This study aimed to develop and validate a nomogram based on clinicopathological characteristics to predict rapid relapse in TNBC patients treated with neoadjuvant chemotherapy (NAC) first. The clinicopathological data of 504 TNBC patients treated with NAC first in Tianjin Medical University Cancer Hospital were analyzed retrospectively, with 109 rapid relapsed patients, and 395 non-rapid relapsed patients, respectively. Based on clinicopathologic characteristics, and follow-up data were analyzed. The independent predictors of clinicopathological characteristics were identified by logistic regression analysis and then used to build a nomogram. The concordance index (C-index), the area under the curve (AUC) of receiver operating characteristic (ROC), and calibration plots were used to evaluate the performance of the model. Univariate and multivariate logistic regression analyses showed that age at diagnosis (age≥50years, OR = 0.325,95% CI:0.137-0.771), Nodal staging (N3 staging, OR = 13.669,95% CI:3.693-50.592),sTIL expression levels (sTIL intermediate expression, OR = 0.272,95% CI:0.109-0.678; sTIL high expression, OR = 0.169,95% CI:0.048-0.594), and NAC response (ORR, OR = 0.059,95% CI:0.024-0.143) were independent predictors of rapid relapse in TNBC patients treated with NAC firstly. Among these independent predictors, age ≥ 50years, sTIL intermediate expression, sTIL high expression, and ORR in NAC were independent protective factors for rapid relapse in TNBC NAC patients. N3 staging was an independent risk factor for rapid relapse in TNBC NAC patients. The ROC curve, calibration curve, and decision curve analysis were used to validate the model. The C-Index of the training sets and validation sets were 0.938 and 0.910, respectively. The Brier scores of the training sets and validation sets were 0.076 and 0.097, respectively. This study developed and verified a nomogram for predicting rapid relapse in TNBC NAC patients, and the predictive model had high discrimination and accuracy.

Comparison of Drug-Free Remission after the End of Phase III Trials of Three Different Anti-IL-23 Inhibitors in Psoriasis.

Knowing the remission duration after biologics discontinuation in patients with psoriasis is important, especially when disease relapse is defined as the restart of systemic agents, because it also reflects the real-world clinical practice when topical treatment alone is not adequate for disease control, and a systemic treatment, including biologic, is needed. Biologics are currently indicated for patients with psoriasis who are candidates for systemic treatments. We included 42 patients who were followed up with regularly after the end of risankizumab, guselkumab and mirikizumab trials and investigated the drug-free remission (DFR). A Kaplan-Meier survival analysis and Cox regression model were employed to identify the possible risk factors for relapse. Overall, 38/42 (90.5%) patients experienced relapses after discontinuing trial biologics during the follow-up period of at least 96weeks and up to 227weeks. In all patients with relapse, the median DFR was 104days. Kaplan-Meier survival analysis revealed a significant 1-year drug-free survival (DFS) difference between risankizumab (Z) and guselkumab (T) + mirikizumab (M) (p = 0.0462). A difference in DFS curves was noted when patients were categorized by disease duration > or ≤ 2years (p = 0.1577) and maintenance of a psoriasis area and severity index score (PASI) of 90 at the end of trials (p = 0.1177). Univariate Cox regression model identified that age [hazard ratio (HR) = 1.030 (1.000-1.060), p = 0.0467] and disease duration [HR = 1.046(1.009-1.084), p = 0.0134] were significantly associated with relapse risk. A risk model was established on the basis of multivariable Cox regression results. Risk value = 0.021038 * Age + 0.515628 * Biologic_type (Z = 0,T/M = 1) + 0.025048 * Disease_Duration. The validated patients were divided into two groups by median risk value (1.5). The high-risk group (risk value > 1.5) had a non-significant higher relapse risk than the low-risk group (risk value < 1.5), with a hazard ratio of 1.62 [95% confidence interval (CI) = 0.82-3.23, p = 0.1809]. Types of biologics used, disease duration > or ≤ 2years, and PASI 90 improvement at the end of trial affect the 1-year DFS after biologics discontinuation. Further studies consisting of a larger patient number and longer follow-up period are needed to verify our findings.

Prognostic and survival factors in head and neck extra-nodal non-Hodgkin's lymphoma

To make a clinical-biological characterization of this pathology and assess the survival of these patients and the associated prognostic factors. A retrospective observational study was designed to identify primary extranodal non-Hodgkin lymphomas of the head and neck diagnosed between January 1, 2005, and January 1, 2016. Cases were considered if they presented with a single tumor in situ or if the extranodal component was clinically predominant. A total of 145 patients were included. Localized stages (I-II) were present in 69.3%. Overall, 91.8% were B-cell phenotype, with diffuse large B-cell lymphoma being the most frequent. Overall, 78% of patients were treated with immunochemotherapy. The overall survival at 3 and 5 years was 75% and 73%, respectively. Adverse prognostic factors were: low hemoglobin, elevated ß2-microglobulin, and lactate dehydrogenase (LDH) levels, Eastern Cooperative Oncology Group (ECOG), stage III/IV, and B symptomatology at diagnosis. The progression-free survival at 3 and 5 years was 71% and 68%. Risk factors for relapse were high ß2-microglobulin, high LDH, and stage III-IV at diagnosis. These pathologies show a good response to treatment with immuno-polychemotherapy. Factors associated with a worse prognosis included low hemoglobin, elevated levels of ß2-microglobulin and LDH, elevated ECOG, stage III/IV, and B symptomatology at diagnosis.

Uveitis as predictor of disease flare after the first anti-TNF withdrawal in oligoarticular and polyarticular juvenile idiopathic arthritis: a multicentric Italian experience.

TNF inhibitors (TNFi) have dramatically changed the prognosis of juvenile idiopathic arthritis (JIA), but it is not clear how and when to stop therapy. We aim to describe a multicentric cohort of JIA treated with adalimumab or etanercept who discontinued the treatment for persistent inactivity and to identify factors associated with relapse. In a multicentric Italian retrospective cohort study, medical records of patients with oligoarticular and polyarticular JIA were evaluated if they stopped therapy for persistent inactivity after the first TNFi. 136 patients were enrolled (102 female, median age at onset 3 years (range 1-15), of whom 55.9% had oligoarticular JIA, 40.4% uveitis and 72.8% ANA positivity. Adalimumab (59.3%) and etanercept (40.7%) were started at a median age of 6 years (range 1-16), TNFi were discontinued after a median time of 30 months (range 6-90), increasing the interval (76.5%), reducing the dose (18.4%) and abrupt discontinuation (16.9%). 79.4% of patients relapsed after a median time of 5 months (range 0.5-66). Patients with uveitis relapsed earlier (log rank χ² 16.4 p<0.0001), while patients who lengthened the interval of administration showed a later relapse (log rank χ² 6.95 p=0.008). Uveitis (HR 2.11 CI 1.34-3.31), age at onset (HR 0.909 CI 0.836-0.987), duration of tapering (HR 0.938 CI 0.893-0.985) and to have a persistent oligoarticular JIA (HR 0.597 CI 0.368-0.968) are significant predictors of disease relapse (Mantel-Cox χ² 34.23 p<0.001). Younger age at onset, uveitis, duration of tapering, and non-persistent oligoarticular JIA seem to be independent risk factors for earlier relapse after the first TNFi withdrawal.
