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.

Kidney transplantation in multiple myeloma in 2023: A short review.

Patients with multiple myeloma (MM) frequently present with kidney involvement, of which a non-negligible proportion will progress to end-stage kidney disease. Kidney transplantation (KT) is the preferred kidney replacement therapy for selected patients; however, there are still many uncertainties regarding its application in MM patients. The risk of hematological relapse and subsequent graft loss or patient death often leads nephrologists to deem these patients unfit for KT. As such, data on KT in MM patients are heterogeneous and originate from individual case reports and small case series. Although MM is still an incurable disease, the addition of newer drugs and autologous hematopoietic stem cell transplant (HSCT) in the standard of care has been increasing patients' overall survival in recent decades. Risk stratification using cytogenetic studies and minimal residual disease detection are helpful in assessing the risk of relapse in patients who attain a complete response after HSCT. The greatest challenges remain the correct identification of patients who will most probably benefit from KT from a survival perspective and the determination of how long relapse-free survival should be before the transplant is performed.

TEDOVA: vaccine OSE2101 +/- pembrolizumab as maintenance in platinum-sensitive recurrent ovarian cancer.

Ovarian cancer is a leading cause of death from gynecological cancers worldwide. Platinum-based chemotherapy provides the cornerstone of the medical management. In first line and subsequent relapses, maintenance strategies are offered to prolong intervals between lines of chemotherapy. Current maintenance options involve bevacizumab and poly ADP-ribose polymerase inhibitors, but these lines of therapy can only be used once in the disease course. Patients in first or second platinum sensitive relapse after poly ADP-ribose polymerase inhibitors and bevacizumab represent an area of unmet medical need. This academic sponsored, international Phase II randomized trial is evaluating the combination of a therapeutic cancer vaccine (OSE2101) with anti-PD1 (pembrolizumab) as maintenance therapy, in patients with platinum-sensitive recurrence regardless of number of prior lines and no progression after platinum-based chemotherapy.Clinical Trial Registration: NCT04713514 (ClinicalTrials.gov).

Machine Learning-Driven Evaluation of Pramipexole and Mood Stabilizer Combination Therapy in Bipolar Disorder

Background Bipolar disorder (BD) requires long-term management to prevent relapse of depressive episodes. The use of pramipexole, a dopamine agonist, in combination with mood stabilizers has been explored for its potential to prevent antidepressant relapse. Objective This case series aims to evaluate the efficacy and safety of pramipexole in combination with mood stabilizers in preventing antidepressant relapse in patients with bipolar disorder. Methods Two patients with bipolar disorder who were at high risk of relapse after discontinuation of antidepressants were treated with pramipexole in combination with mood stabilizers. Clinical assessments were conducted using the Mood Disorder Questionnaire (MDQ), Clinical Global Impression-Severity (CGI-S), Hamilton Depression Rating Scale (HDRS), and Global Assessment of Functioning (GAF) before and after the addition of pramipexole. Results The combination therapy of pramipexole and mood stabilizers effectively prevented relapse in both patients. MDQ scores decreased, CGI-S scores improved, HDRS scores reduced, and GAF scores increased, with no significant adverse effects reported over a follow-up period of 12 months. Conclusion Pramipexole in combination with mood stabilizers appears to be an effective and safe strategy for preventing antidepressant relapse in patients with bipolar disorder. These findings suggest that this combination therapy could be considered for patients at high risk of relapse after antidepressant discontinuation.

Neoadjuvant Statistical Algorithm to Predict Individual Risk of Relapse in Patients with Resected Liver Metastases from Colorectal Cancer.

(1) Background: Liver metastases (LM) are the leading cause of death in colorectal cancer (CRC) patients. Despite advancements, relapse rates remain high and current prognostic nomograms lack accuracy. Our objective is to develop an interpretable neoadjuvant algorithm based on mathematical models to accurately predict individual risk, ensuring mathematical transparency and auditability. (2) Methods: We retrospectively evaluated 86 CRC patients with LM treated with neoadjuvant systemic therapy followed by complete surgical resection. A comprehensive analysis of 155 individual patient variables was performed. Logistic regression (LR) was utilized to develop the predictive model for relapse risk through significance testing and ANOVA analysis. Due to data limitations, gradient boosting machine (GBM) and synthetic data were also used. (3) Results: The model was based on data from 74 patients (12 were excluded). After a median follow-up of 58 months, 5-year relapse-free survival (RFS) rate was 33% and 5-year overall survival (OS) rate was 60.7%. Fifteen key variables were used to train the GBM model, which showed promising accuracy (0.82), sensitivity (0.59), and specificity (0.96) in predicting relapse. Similar results were obtained when external validation was performed as well. (4) Conclusions: This model offers an alternative for predicting individual relapse risk, aiding in personalized adjuvant therapy and follow-up strategies.

Long-term exposure and response to azacitidine for post-hematopoietic stem cell transplantation relapse of early T-cell precursor acute lymphoblastic leukemia: a case report and review of the literature

Adult T-cell acute lymphoblastic leukemia has a poor outcome after relapse. Because the subtype of early T-cell precursor displays characteristics close of those of acute myeloid leukemia, such as epigenetic dysregulation, hypomethylating agents might prove of interest. We describe the case of a patient relapsing 3 months only after allogeneic stem cell transplantation who achieved complete remission on azacitidine, and is still on therapy 9 years later. We discuss the biological background of this very long-term response, underlining the immunological effects of hypomethylating agents, and the perspectives opened by combination of hypomethylating agents with other drugs such as venetoclax.

Clinical and sociodemographic characteristics associated with relapse following electroconvulsive therapy for bipolar disorder.

Electroconvulsive therapy (ECT) is an effective treatment for bipolar disorder, but relapse following a successful ECT series is common. We aimed to identify clinical and sociodemographic characteristics associated with the risk of relapse following ECT in bipolar disorder. Using data from nationwide Danish registers, we identified all patients receiving their first ECT series with an indication diagnosis of bipolar disorder between 2006 and 2018. We then followed these patients for relapse, defined as either psychiatric admission or a new ECT series, for 6 months following ECT. Associations between clinical and sociodemographic characteristics and relapse were examined via multivariable Cox proportional-hazards regression, yielding adjusted hazard rate ratios (aHRR). Of the 1473 patients receiving ECT for bipolar disorder (62% females, mean age = 53 years), 34% met the relapse criterion. The following characteristics were associated with an elevated risk of relapse; age <40 (aHRR = 1.54, 95% CI = 1.05-2.26); being a pensioner (aHRR = 1.73, 95% CI = 1.29-2.32), indication diagnosis for ECT being psychotic mania (aHRR = 1.63, 95% CI = 1.16-2.28), psychotic bipolar depression (aHRR = 1.37, 95% CI = 1.06-1.80), mixed episode (aHRR = 1.51, 95% CI = 1.13-2.02), or other bipolar episodes (aHRR = 1.68, 95% CI = 1.28-2.21); and treatment with antipsychotics prior to the course of ECT (aHRR = 1.32, 95% CI = 1.04-1.67). Patients with bipolar disorder face a particularly high risk of relapse following ECT if they present with the following characteristics when initiating ECT: age <40, being a pensioner, having received treatment with an antipsychotic before initiating ECT, or having psychotic bipolar depression, psychotic mania, mixed episodes, or other bipolar episodes as the indication for ECT. These findings may guide relapse monitoring following ECT in bipolar disorder.
