Relapse In Patients Research Articles

Relapse prevention following guided self-help for common health problems: A Scoping Review

Abstract Purpose To gain an in-depth understanding of interventions, tools, and resources available focused on maintaining recovery and preventing relapse for patients with anxiety and/or depression symptoms following guided self-help (GSH). Methods The literature search was conducted on four electronic databases from inception until May 2024 (PsycINFO, CINAHL Plus, PubMed and Web of Science). Additional searches were also conducted through other sources, including Grey Literature Databases, Google Search Engine, Citations and contacting experts in the field. All identified articles were screened for eligibility by two independent reviewers and quality appraised. Results A total of 1277 records across databases and other sources were identified. After removing duplicates, 511 were screened for eligibility. A total of six references met the inclusion criteria and were included in the review. Three peer-reviewed publications were identified, and all reported an intervention targeting relapse prevention following GSH which included monthly telephone follow-up calls. The other three sources included two workbooks and a mobile application developed and completed towards the final GSH sessions and used following treatment. All of the articles highlight the importance of independently learning and practicing skills and strategies to ease an individuals’ symptoms following discharge from GSH. Conclusions The current review found limited evidence surrounding recovery and relapse prevention interventions following GSH. Developing this field of research by further creating and testing relapse prevention interventions can provide an understanding of the core components needed in such tools, to successfully maintain treatment gains over time and support individuals to continue their recovery journey.

Early autologous and/or allogeneic stem cell transplantation for adult patients with advanced stage T- lymphoblastic leukemia/lymphoma or Burkitt lymphoma. A retrospective single-centre analysis

T-cell acute lymphoblastic leukemia/lymphoma (T-ALL/LBL) and Burkitt lymphoma (BL) are uncommon, highly aggressive diseases originating either from immature precursor T cells or from mature B cells in BL. We retrospectively analyzed the outcome of an early autologous and/or allogeneic stem cell transplantation (SCT) concept in 28 patients with advanced stage T-ALL/LBL and BL after three to four remission induction/consolidation chemotherapy cycles. Considering only patients in first complete remission (CR), the 5-year overall survival (OS) and event-free survival (EFS) was 91% in patients with BL and 73% in patients with T-ALL/LBL with a 5-year relapse incidence (RI) of 9% in patients with BL and 27% in patients with T-ALL/LBL. All relapsing patients finally succumbed to the disease (n = 10) or complications/toxicity after having received a salvage allogeneic transplant (n = 5). Despite the low patient number our retrospective single-centre analysis by incorporating an early intensive high-dose chemo-/radiotherapy strategy with either autologous or allogeneic stem cell transplantation, although preliminary, show promising long-term outcome. Further studies are highly warranted to better define those patients who might benefit most from such a treatment approach.

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.

Proteomic profile of extracellular vesicles from plasma and CSF of multiple sclerosis patients reveals disease activity-associated EAAT2

Background and objectivesThere is an urgent need to discover blood-based biomarkers of multiple sclerosis (MS) to better define the underlying biology of relapses and monitor disease progression. The main goal of this study is to search for candidate biomarkers of MS relapses associated with circulating extracellular vesicles (EVs), an emerging tool for biomarker discovery.MethodsEVs, purified from unpaired plasma and CSF samples of RRMS patients by size-exclusion chromatography (SEC), underwent proteomic analysis to discover novel biomarkers associated with MS relapses. The candidate biomarkers of disease activity were detected by comparison approach between plasma- and CSF-EV proteomes associated with relapses. Among them, a selected potential biomarker was evaluated in a cohort of MS patients, using a novel and highly reproducible flow cytometry-based approach in order to detect low abundant EV subsets in a complex body fluid such as plasma.ResultsThe proteomic profiles of both SEC-purified plasma EVs (from 6 patients in relapse and 5 patients in remission) and SEC-purified CSF EVs (from 4 patients in relapse and 3 patients in remission) revealed a set of proteins associated with MS relapses significant enriched in the synaptic transmission pathway. Among common proteins, excitatory amino-acid transporter 2, EAAT2, responsible for the majority of the glutamate uptake in CNS, was worthy of further investigation. By screening plasma samples from 110 MS patients, we found a significant association of plasma EV-carried EAAT2 protein (EV-EAAT2) with MS relapses, regardless of disease-modifying therapies. This finding was confirmed by investigating the presence of EV-EAAT2 in plasma samples collected longitudinally from 10 RRMS patients, during relapse and remission. Moreover, plasma EV-EAAT2 levels correlated positively with Expanded Disability Status Scale (EDSS) score in remitting MS patients but showed a negative correlation with age in patients with secondary progressive (SPMS).ConclusionOur results emphaticize the usefulness of plasma EVs as a source of accessible biomarkers to remotely analyse the CNS status. Plasma EV-EAAT2 showed to be a promising biomarker for MS relapses. Further studies are required to assess the clinical relevance of this biomarker also for disability progression independent of relapse activity and transition from RRMS towards SPMS.

Combinations of immunomodulatory agents for prevention of uveitis relapse in patients with severe Behçet's disease already on corticosteroid therapy: a randomised, open-label, head-to-head trial

Data from head-to-head trials of immunomodulatory therapies for Behçet's disease are scarce. We aimed to compare the efficacy and safety of ciclosporin, interferon alfa-2a, and adalimumab, each combined with corticosteroids, in preventing uveitis relapse in patients with severe Behçet's disease. We did a randomised, open-label, assessor-masked, head-to-head trial at a large, specialised uveitis centre in Chongqing, China. Patients aged 18 years or older with severe Behçet's disease uveitis on corticosteroids and naive to anti-TNF therapy were eligible. Patients were randomly assigned in a 1:1:1 ratio to ciclosporin (2-5 mg/kg per day orally), interferon alfa-2a (3 million IU per day subcutaneously), or adalimumab (40 mg every 2 weeks subcutaneously), each combined with a tapering dose of corticosteroids with subsequent dose adjustments. The primary outcome was the annualised relapse rate of uveitis, assessed in the full analysis set (all randomly assigned patients with at least one post-baseline assessment). The non-inferiority margin of difference between the interferon alfa-2a and adalimumab groups was set to 1·0 for the primary outcome. Safety was assessed in all patients who received at least one dose of trial drugs. Individuals with lived experience of Behçet's disease uveitis were involved in the trial design and implementation. This study is registered with Chinese Clinical Trial Registry, ChiCTR2000031637. The trial is ongoing, but is closed to new participants. Between May 12, 2020, and Feb 22, 2022, a total of 270 patients (mean age 38·1 years [SD 9·8]; 213 [79%] men, 57 [21%] women; 270 [100%] east Asian ethnicity) were randomly assigned to ciclosporin, interferon alfa-2a, or adalimumab (n=90 in each group); 261 patients were included in the full analysis set. For the primary outcome, the least-squares mean was 1·84 (95% CI 1·40 to 2·44) with ciclosporin, 1·44 (1·10 to 1·89) with interferon alfa-2a, and 0·95 (0·64 to 1·40) with adalimumab. The annualised relapse rate was significantly higher in patients receiving ciclosporin than in those receiving adalimumab (least-squares mean difference 0·90 [95% CI 0·27 to 1·53]; p=0·0054 for superiority). The least-squares mean difference between interferon alfa-2a and adalimumab was 0·50 (-0·04 to 1·04), which did not meet non-inferiority criteria (p=0·034 for non-inferiority). The primary outcome did not differ substantially between interferon alfa-2a and ciclosporin (least-squares mean difference -0·40 [-1·05 to 0·25]; p=0·23 for superiority). Serious adverse events were reported in 12 (13%) of 90 patients on ciclosporin plus corticosteroids, eight (9%) of 90 patients on interferon alfa-2a plus corticosteroids, and seven (8%) of 90 patients on adalimumab plus corticosteroids. There were no treatment-related deaths. Adalimumab plus corticosteroids was superior to ciclosporin plus corticosteroids with respect to uveitis relapse rate in patients with severe Behçet's disease naive to anti-TNF therapy, and interferon alfa-2a plus corticosteroids was not found to be non-inferior to adalimumab plus corticosteroids or superior to ciclosporin plus corticosteroids.

Immunosuppressive agents or intravenous immunoglobulin in addition to glucocorticoids in the treatment of Susac syndrome: a French national cohort study

Susac syndrome is a rare disease affecting mainly young women and is characterised by an occlusive microvessel disease limited to the brain, retina, and inner ear. No randomised controlled trial has been published or declared as ongoing to investigate treatments for Susac syndrome. We aimed to compare the effect of glucocorticoids given alone or in combination with immunosuppressive agents or intravenous immunoglobulin for the prevention of relapse in patients with Susac syndrome. The Phenotypic and Etiological Characterization of Susac Syndrome-National Clinical Research Hospital Program study is a prospective national cohort study that started enrolling on Nov 29, 2011, and included all consecutive patients aged 18 years or older with Susac syndrome who were referred to the French reference centre (Department of Internal Medicine, Bichat-Claude Bernard Hospital, Paris). Susac syndrome was defined by either the triad of encephalopathy with typical brain MRI abnormalities, cochleo-vestibular damage, and multiple occlusions of retinal central artery branches, or at least two of the three criteria without any alternative diagnosis. Collected data included fundoscopy, retinal angiography, audiometry, cerebrospinal fluid, brain MRI, and treatment received at diagnosis; months 1, 3, 6, and 12 after diagnosis; and then annually for 5 years or in the case of a relapse. The primary outcome was defined as the first relapse occurring within a 36-month follow-up period from the first day of treatment, characterised by new clinical symptoms or signs, and new abnormalities observed on retinal angiography, audiometry, or brain MRI, necessitating treatment intensification. There was no involvement of people with lived experience at any stage. The study is registered at ClinicalTrials.gov, NCT01481662. Between Nov 29, 2011, and Dec 2, 2022, 64 patients were included in the study, with a mean age at diagnosis of 35 years (SD 11); 41 (64%) were women and 23 (36%) were men. At diagnosis, 60 patients received glucocorticoids; 40 (63%) of 64 patients received glucocorticoids alone as a first-line therapy while 20 (31%) received glucocorticoids in combination with immunosuppressive agents or intravenous immunoglobulin. Overall, 46 (72%) of 64 patients had a first relapse with a median relapse-free survival time of 3·96 months (95% CI 2·24-16·07). Comparison of relapse-free survival showed no significant difference between the two treatment strategies (hazard ratio [HR] 1·11 [95% CI 0·56-2·17], p=0·76), compared with glucocorticoids alone as the reference group. In patients who first relapsed while treated with glucocorticoids alone, there was no significant difference in second relapse-free survival between those who did or did not receive immunosuppressive agents or intravenous immunoglobulin as a second-line therapy (HR 2·66 [95% CI 0·63-11·18], p=0·18). The combination of glucocorticoids with immunosuppressive agents or intravenous immunoglobulin did not appear to reduce the risk of Susac syndrome relapse compared with glucocorticoids alone. Our findings did not support the systematic use of immunosuppressive agents in Susac syndrome. French Ministry of Health.

Analysis of influencing factors of recurrence after en bloc spondylectomy of spinal tumors

Objectives: To investigate the survival and tumor recurrence after en bloc spondylectomy of spinal tumor and analyze the risk factors of postoperative tumor recurrence. Methods: This is a retrospective case series study. Data of 101 patients undergoing en bloc spondylectomy of spinal tumors in the Musculoskeletal Tumor Center, Peking University People's Hospital from December 2006 to June 2022 were analyzed. There were 58 males and 43 females, aged (38.2±15.8) years (range: 10 to 79 years) at the time of surgery; the follow-up time was(44.0±36.0) months (range: 12 to 171 months).Among them, there were 25 relapsed patients, with 7 females and 18 males; aged (34.8±16.3) years (range: 12 to 66 years) at the time of surgery. The types of tumors included 5 giant cell tumors of bone, 6 osteosarcomas, 1 chordoma, 5 chondrosarcomas, 1 undifferentiated sarcoma, 1 fibrosarcoma, 2 Ewing sarcomas, 3 metastases and 1 malignant giant cell tumor of bone. Survival analysis of overall and relapsed patients were performed using the Kaplan-Meier curves. A segmented regression model was used to fit the sequence of recurrence rate changes over time since admission and identify change points for further analysis on risk factors. Univariate and multivariate Logistic regression analysis were performed to assess risk factors associated with recurrence rate; results from multivariate regression analysis were presented using a forest plot. Results: The tumor recurrence rate after en bloc spondylectomy was 24.8% (25/101).The overall median recurrence-free survival after en bloc spondylectomy was 161 months (95%CI: 92 months to NA).The median recurrence-free survival of recurrent patients was 13 months (95%CI: 12 to 27 months).Regarding the classification based on tumor malignancy, and relapse-free survival of metastatic tumors was significantly shorter (P=0.007); and among the surgical margin groups, relapse-free survival of R0 group was significantly better than the R1 and R2 groups (P<0.01). According to the segmented regression model, the tumor recurrence rate for en bloc spondylectomy showed a significant downward trend over time, with relatively higher recurrence rates before 2009 and a relatively stable trend after 2014. The results of univariate analysis showed that surgical margin and time of admission were the influencing factors of patient recurrence. The results of multivariate analysis showed that the R1 resection(OR=13.453,95%CI:2.897 to 97.941,P=0.002) and R2 resection(OR=11.379,95%CI:2.658 to 79.429,P=0.003) were independent influencing factor affecting patient recurrence. Conclusions: The overall tumor recurrence rate after en bloc spondylectomy was high. The surgical margin of tumor resection is an independent risk factor affecting tumor recurrence. Specifically, R2 and R1 resections significantly increase the risk of tumor recurrence.

The efficacy of gemcitabine and docetaxel chemotherapy for the treatment of relapsed and refractory osteosarcoma: A systematic review and pre-clinical study.

Osteosarcoma is the most common primary malignancy of the bone. There is a lack of effective treatments for patients who experience relapsed osteosarcoma. One treatment for relapsed patients is gemcitabine and docetaxel combination chemotherapy (GEMDOX). This systematic review aimed to establish the efficacy of this chemotherapy regimen, as well as identify the common severe toxicities that are associated with it. Resistant osteosarcoma cell lines developed from MG-63 and HOS-143B were used to represent relapsed osteosarcoma patients in a pre-clinical study. We identified 11 retrospective and Phase II studies that were suitable for inclusion in our review. 10.65% of patients had a response to gemcitabine and docetaxel combination therapy and the disease control rate was 35% (n = 197). 36%, 35.3% and 18.04% of patients experienced grade 3 or 4 neutropenia, thrombocytopenia and anaemia respectively (n = 133). Male patients (X2 = 9.14, p < 0.05) and those below the age of 18 (X 2 = 10.94, p < 0.05) responded better to GEMDOX treatment than females and patients older than 18 years. The resistant osteosarcoma cell lines remained sensitive to either single-agent gemcitabine, docetaxel, and the combination of both. Cisplatin-resistant models (MG-63/CISR8 & HOS-143B/CISR8) were the most responsive to GEMDOX treatment compared to doxorubicin, methotrexate, and triple-combination resistant models. GEMDOX treatment has potential efficacy in relapsed osteosarcoma patients especially those with cisplatin resistance. To directly compare the efficacy of GEMDOX therapy against other therapies randomised phase III clinical trials with adequate patient follow up must be performed to improve treatment options for osteosarcoma.

Constraint on boric acid resistance and tolerance evolvability in Candida albicans.

Boric acid is a broad-spectrum antimicrobial used to treat vulvovaginal candidiasis when patients relapse on the primary azole drug fluconazole. Candida albicans is the most common cause of vulvovaginal candidiasis, colloquially referred to as a "vaginal yeast infection". Little is known about the propensity of C. albicans to develop BA resistance or tolerance (the ability of a subpopulation to grow slowly in high levels of drug). We evolved 96 replicates from eight diverse C. albicans strains to increasing BA concentrations to test the evolvability of BA resistance and tolerance. Replicate growth was individually assessed daily, with replicates passaged when they had reached an optical density consistent with exponential growth. Many replicates went extinct quickly. Although some replicates could grow in much higher levels of BA than the ancestral strains, evolved populations isolated from the highest terminal BA levels (after 11 weeks of passages) surprisingly showed only modest growth improvements and only at low levels of BA. No large increases in resistance or tolerance were observed in the evolved replicates. Overall, our findings illustrate that there may be evolutionary constraints limiting the emergence of BA resistance and tolerance, which could explain why it remains an effective treatment for recurrent yeast infections.

Introducing the Arabic inflammatory bowel disease disk as a tool for assessing disability in patients with inflammatory bowel disease in Jordan

Background and study aimInflammatory bowel diseases (IBD) are chronic relapsing-remitting disorders of the gastrointestinal tract. IBD causes significant impairment in the patient’s quality of life that should be assessed and monitored in a flexible and easy way. The IBD-Disability Index (IBD-DI) is the only validated tool to assess disability in IBD patients, but it is difficult to use in clinical practice. The IBD Disk is a new shortened, self-administering version of the IBD-DI that allows quick assessment of IBD patients and tracks changes in disease burden over time. However, the IBD Disk has not been used yet in clinical practice in Jordan. The aim of the study was to translate the IBD Disk to Arabic language and introduce it in clinical practice in Jordan. Patients and methodsAfter translating the original IBD Disk to Arabic language, IBD patients referred to outpatient clinic or admitted to the medical department at the new Al-Hussein hospital, Al-Salt, Jordan, from September 2021 until March 2022, filled the translated IBD Disk. ResultsA total of 50 IBD patients (52 % males) were included in the study and filled the IBD Disk. The IBD Disk was easy to complete by the patients. Energy, regulating defecation, and emotions were the most disabling domains for relapsing patients. Polygonal shape area of the mean for IBD Disk scores decreased during remission. Education & work and energy had the strongest correlation at relapse. ConclusionThe IBD Disk is a reliable visual representation of IBD disability. In this study, a translated version of IBD Disk to Arabic language was introduced for the first time in clinical practice in Jordan. The reduction in the polygonal shape area of the scores’ mean represents decreased disease burden.

Fasting insulinemia as biomarker of illness relapse in patients with severe mental illness?

Severe Mental Illness (SMI) is often associated with metabolic alteration and/or metabolic syndrome, which may determine an increased mortality due to a further increased cardiovascular risk. The relationship with metabolic syndrome is often bidirectional, resulting in a pathoplastic effect of these dysmetabolisms. Among the several hormones involved, insulin appears to play a key role, albeit not entirely clear. The aim of our real-world cross-sectional observational study is to investigate a set of metabolic biomarkers of illness relapse/recurrence/onset in a cohort of 310 adult SMI inpatients consecutively admitted to the Psychiatry Clinic of the Azienda Ospedaliero Universitaria of Marche, in Ancona (Italy), between February 2021 and February 2024. According to the stepwise multivariate regression model, a higher number of acute episodes per year was positively predicted by the age of illness onset, the lifetime number of suicidal attempts and fasting insulinemia and negatively by the participant’s age. A second stepwise multivariate regression model using only the metabolic characteristics as independent variables, found that a higher number of acute episodes per year was predicted positively by the fasting insulinemia and red blood cells and negatively by the abdominal circumference. Overall, our findings could provide practical implications for the treatment and management of SMI patients, emphasizing the importance of monitoring and managing metabolic factors, particularly insulinemia, metabolic syndrome and insulin resistance. Finally, insulinemia could potentially act as metabolic biomarker of illness relapse, though more larger and longitudinal studies should be carried out to confirm these results.

MYC translocation is a valuable marker for the development and relapse of extramedullary disease in multiple myeloma.

To study the cytogenetic characteristics of extramedullary disease (EMD) in patients with multiple myeloma (MM) and their impact on prognosis. Patients with newly diagnosed MM (NDMM) at Peking Union Medical College Hospital (Beijing, China) between June 2007 and December 2019 were recruited for this study. Demographic information, clinical data, fluorescence in situ hybridization (FISH) results of marrow and tissue samples, and survival outcome data were collected. A total of 439 patients with NDMM were divided into those without EMD (non-EMD, n = 339), those with EMD with primary paraosseous plasmacytoma (pEMD-B, n = 48), those with primary EMD with soft-tissue involvement (pEMD-S, n = 33), and those with secondary EMD (sEMD, n = 19). The incidence of EMD was 18.5% (81/439) at diagnosis and 22.8% (100/439) throughout the disease course. Comparison of FISH results showed a higher proportion of RB1 deletion (n = 20; 60.0% vs. 20.0%, p = .013) and MYC translocation (n = 12; 44.4% vs. 12.5%, p = .041) in the extramedullary tissues than in the paired bone marrow samples. At diagnosis, the percentage of MYC translocations in the sEMD group was notably higher than that in the non-EMD group (55.6% vs. 15.5%, p = .012). The median overall survival (OS) of patients with pEMD-S (32 months) and sEMD (17 months) was significantly shorter (both p = .001) than that of non-EMD patients (60 months). Soft-tissue EMD can be considered a high-risk condition, even in the era of novel agents. MYC translocation can serve as a valuable marker that correlates with extramedullary spread and relapse in patients with MM and should be considered for inclusion in routine FISH panels in clinical practice.

The Potential of Molecular Remission: Tissue Neutrophil Elastase Is Better Than Histological Activity for Predicting Long-Term Relapse in Patients With Ulcerative Colitis in Endoscopic Remission.

Growing interest exists in deep remission, beyond clinical and endoscopic remission, to enhance long-term prognosis in patients with ulcerative colitis (UC). Our study aimed to evaluate the risk of relapse according to tissue expression levels of calprotectin and neutrophil elastase (NE) in patients with quiescent UC. Rectal biopsies were performed on 218 patients with UC in clinical and endoscopic remission. Histological activity was prospectively scored using the Robarts Histological Index. Tissue calprotectin and NE levels were evaluated using immunohistochemistry. Optimal tissue calprotectin and NE cutoffs for relapse were determined using log-rank analysis. Cox proportional hazard analyses evaluated relapse risk factors. Tissue calprotectin and NE levels were significantly higher in patients with histological activity than in those in histological remission (P < .001). The optimal cutoffs of tissue calprotectin and NE for relapse were 10.61 and 22.08permm2, respectively. The 3-year clinical relapse risk was significantly lower in the low-tissue NE group than in the high-tissue NE group (P = .009); however, it did not differ between the low- and high-tissue calprotectin group (P = .094). In multivariate analyses, a low level of tissue NE expression was independently associated with a lower risk of 3-year clinical relapse (adjusted hazard ratio = 0.453, 95% confidence interval = 0.225-0.911, P = .026), unlike histological index and tissue calprotectin. In patients with UC who have achieved clinical and endoscopic remission, tissue expression of NE is a better predictor of long-term relapse than histological activity.

Relapse Predictors in Antineutrophil Cytoplasmic Antibody (ANCA)-Associated Vasculitis.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAVs) are a group of rare diseases with a chronic and relapsing course. Recent treatment guidelines offer many therapeutic options depending mainly on the type of diagnosis and disease manifestations. Areas that remain under discussion include whether all patients diagnosed with AAV belong to a homogeneous group with a similar prognosis at baseline or if the type and duration of remission-inducing treatment should depend on factors other than just diagnosis and disease severity. The aim of this review is to present the recent literature on the tools available to use while evaluating the risk of relapse in patients upon presentation as well as potential biomarkers of proceeding flare in patients upon remission.

Assessment of the Circulating PD-1 and PD-L1 Levels and P53 Expression as a Predictor of Relapse in Pediatric Patients with Wilms Tumor and Hypernephroma.

Background/Objectives: Wilms tumor (WT) is the most common form of pediatric renal tumor, accounting for over 90% of cases followed by hypernephroma. Some pediatric patients with WT (10%) experience relapse or metastasis and have poor survival rates. PD-L1 assists cancer cells in escaping damage from the immune system. P53 mutations are found in relapsed WT tumor samples. We hypothesized that testing circulating PD-1 and PD-L1 and P53 expression levels could offer a simple method to predict patient relapse and explore novel treatments for pediatric WTs and hypernephroma. Methods: Flow cytometric detection of cPD-1, cPD-L1, and P53 expression in relapsed and in-remission WT and hypernephroma before and after one year of chemotherapy was performed. Results: Our data shows increased levels of cPD-L1 in relapsed pediatric patients with WT or hypernephroma before and after chemotherapy. There were also slight and significant increases in cPD-1 levels in relapsed groups before chemotherapy. Additionally, we observed significant decreases in P53 expression after one year of chemotherapy in relapsed pediatric patients. Conclusions: Our study found that circulating PD-L1 can be used as a predictor marker for WT and hypernephroma relapse. In conclusion, these circulating markers can assist in monitoring relapse in WT and hypernephroma patients without the need for several biopsies.

Large vessel vasculitis is a risk factor for relapse only in giant cell arteritis patients without polymyalgia rheumatica.

To evaluate differences in presentation and outcome of giant cell arteritis (GCA) patients with and without large vessel vasculitis (LVV) and according to the extent and severity of LVV. Consecutive patients diagnosed with GCA between 2003 and 2020 who have had FDG PET imaging at diagnosis ≤3 days after initiation of glucocorticoids and followed for ≥12 months at the University Hospitals Leuven (Belgium), were included retrospectively. PET scans were visually scored (0-3) in 7 vascular areas and a total vascular score (TVS) was calculated. LVV was defined as FDG uptake ≥2 in any large vessel. We included 238 GCA patients, of which 169 (71%) had LVV. LVV patients were younger (69 vs 74 years, p< 0.001) and more frequently female (72% vs 49%, p= 0.001). In patients without PMR symptoms, the presence of LVV was associated with relapse (aOR 3.05 [95%CI 1.32-7.43], p= 0.011) and with a lower probability of stopping glucocorticoids (aHR 0.59 [95%CI 0.37-0.94], p= 0.025). However, in those with PMR symptoms, there was no difference in relapse risk (aOR 1.20 [95%CI 0.53-2.66], p= 0.657) and in the probability of stopping glucocorticoids (aHR 1.25 [95%CI 0.75-2.09], p= 0.394) between patients with and without LVV. A higher TVS was associated with an increased risk of relapse (aOR 1.09 [95%CI 1.04-1.15], p= 0.001] in patients without PMR symptoms, but not in those with PMR symptoms (aOR 1.01 [95%CI 0.96-1.07], p= 0.693). LVV is a risk factor for relapse in GCA patients without PMR symptoms with a higher relapse risk in those with higher TVS.

Leucine-rich alpha-2 glycoprotein is useful in predicting clinical relapse in patients with Crohn's disease during biological remission.

Serum leucine-rich alpha-2 glycoprotein (LRG) is a potential biomarker of Crohn's disease (CD). This study aimed to evaluate the usefulness of LRG in predicting clinical relapse in patients in remission with CD. This retrospective observational study assessed the relationships among patient-reported outcome (PRO2), LRG, and other blood markers. The influence of LRG on clinical relapse was assessed in patients in remission with CD. Data of 94 patients tested for LRG between January 2021 and May 2023 were collected. LRG level did not correlate with PRO2 score (ρ = 0.06); however, it strongly correlated with C-reactive protein (CRP) level (r=0.79) and serum albumin level (r=-0.70). Among 69 patients in clinical remission, relapse occurred in 22 patients (31.9%). In the context of predicting relapse, LRG showed the highest area under the curve, followed by CRP level, platelet count, and albumin level. Multivariate analysis revealed that only LRG (P= 0.02) was an independent factor for predicting clinical remission. The cumulative non-relapse rate was significantly higher in patients with LRG < 13.8 μg/mL than in patients in remission with LRG ≥ 13.8 μg/mL and normal CRP level (P= 0.002) or normal albumin level (P= 0.001). Cumulative non-relapse rate was also higher in patients with LRG < 13.8 μg/mL compared to those with LRG ≥ 13.8 μg/mL in patients with L3 or B2+B3 of Montreal calcification. LRG is useful in predicting clinical relapse in patients with CD during biological remission. LRG is a useful biomarker for predicting prognosis, even in patients with intestinal stenosis, or previous/present fistulas.
