Clinical, Genomic, and Transcriptomic Characteristics of Patients with Metastatic Renal Cell Carcinoma Who Developed Thromboembolic Events.

Thromboembolic events (TE) are a common complication in patients with metastatic renal cell carcinoma (mRCC) and are associated with poorer clinical outcomes. However, the incidence of TE and clinical and genomic characteristics of patients with mRCC who develop this complication are poorly understood. Herein, we describe the incidence and clinical features of patients with mRCC with or without TE at our institution, and examine their association with the underlying genomic and transcriptomic characteristics of the tumor. This retrospective study included all consecutive cases of mRCC seen at our institution. A CLIA-certified lab performed tumor genomics and transcriptomics. Patients were classified based on the presence of a TE within the first year of diagnosis. Three hundred and seventy patients with mRCC were included in the study. TE was seen in 11% (42) of the patients. Patients with favorable International mRCC Database Consortium (IMDC) risk were less likely to develop a TE. In contrast, patients receiving combination treatment with a tyrosine kinase inhibitor (TKI) and an immune checkpoint inhibitor were more likely to develop a TE. No difference in overall survival among patients with or without TE was observed (52 vs. 55 months; HR 0.85, 95% CI 0.5574-1.293, p = 0.24). The most upregulated pathways in mRCC with TEs versus those without were the xenobiotic metabolism and mTORC1 signaling pathways. Our findings suggest potential biomarkers that, after external validation, could be used to better select patients who would benefit from prophylactic anticoagulation.

NRG-BN002: Phase I study of ipilimumab, nivolumab, and the combination in patients with newly diagnosed glioblastoma.

Immune checkpoint inhibitors (ICIs) have efficacy in several solid tumors but limited efficacy in glioblastoma (GBM). This study evaluated the safety of anti-CTLA-4 and anti-PD-1 ICIs alone or in combination in newly diagnosed GBM after completion of standard radiochemotherapy with the subsequent intent to test combinatorial ICIs in this setting. The primary endpoint was dose-limiting toxicity (DLT) for adults with unifocal, supratentorial newly diagnosed GBM after resection and chemoradiation. Ipilimumab and nivolumab were tested separately and in combination with a planned expansion cohort dependent upon DLT results. Thirty-two patients were enrolled at 9 institutions: 6 to each DLT assessment cohort and 14 to the expansion cohort. Median age: 55 years, 67.7% male, 83.9% White. Treatment was well tolerated with 16% Grade 4 events; the combination did not have unexpectedly increased toxicity, with no Grade 5 events. One DLT was seen in each single-agent treatment; none were observed in the combination, leading to expanded accrual of the combined treatment. The median follow-up was 19.6 months. For all patients receiving combination treatment, median overall survival (OS) and progression-free survival (PFS) were 20.7 and 16.1 months, respectively. IPI and NIVO are safe and tolerable with toxicities similar to those noted with other cancers when given in combination with adjuvant temozolomide for newly diagnosed GBM. Combination IPI + NIVO is not substantially more toxic than single agents. These results support a subsequent efficacy trial to test the combination of ICIs in Phase II/III for patients with newly diagnosed GBM. NCT02311920.

Retrospective Large Database Study of Central Serous Chorioretinopathy Treatments and Visual Outcomes Analysis in the United States.

Purpose: To evaluate a large database detailing the changes in visual acuity (VA) and central subfield thickness after various treatments for central serous chorioretinopathy (CSCR). Methods: A retrospective analysis was performed of patients with CSCR from January 2015 to September 2022 using the Vestrum Health Retina Database of aggregated de-identified electronic medical records from retina specialists in the United States. The cases of CSCR were categorized by age, sex, and treatment provided. Results: The annual incidence of CSCR was 1.72% (61 755 of 3 598 672 patient eyes), with a mean patient age of 53 years. Male eyes comprised 71.8% of the patient population. Eighty-five percent of patients received no treatment within 1 year of diagnosis. Of the patients needing treatment, 21% received thermal laser therapy, 23% photodynamic therapy, and 49% antivascular endothelial growth factor (anti-VEGF) intraocular injection. Patients not receiving treatment had the best baseline and 1-year VA. All treatment groups had an increased percentage of patients gaining letters compared with patients not receiving treatment. Conclusions: Although most patients did not require treatment, those who received treatment generally did well, with a large proportion having visual gain. Statistical analysis suggests treatment has a positive impact on VA outcomes. Patients receiving combination treatment were older and had the least visual gain of the treated cohorts. Younger patients with CSCR treated with anti-VEGF (and without a secondary diagnosis of macular degeneration) had the greatest increase in VA at 1 year.

Cloxacillin plus fosfomycin versus cloxacillin alone for methicillin-susceptible Staphylococcus aureus bacteremia: a randomized trial

Treatment failure occurs in about 25% of patients with methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia. We assessed whether cloxacillin plus fosfomycin achieves better treatment success than cloxacillin alone in hospitalized adults with MSSA bacteremia. We conducted a multicenter, open-label, phase III–IV superiority randomized clinical trial. We randomly assigned patients (1:1) to receive 2 g of intravenous cloxacillin alone every 4 h or with 3 g of intravenous fosfomycin every 6 h for the initial 7 days. The primary endpoint was treatment success at day 7, a composite endpoint with the following criteria: patient alive, stable or with improved quick Sequential Organ Failure Assessment score, afebrile and with negative blood cultures for MSSA, adjudicated by an independent committee blinded to treatment allocation. We randomized 215 patients, of whom 105 received cloxacillin plus fosfomycin and 110 received cloxacillin alone. We analyzed the primary endpoint with the intention-to-treat approach in 214 patients who received at least 1 day of treatment. Treatment success at day 7 after randomization was achieved in 83 (79.8%) of 104 patients receiving combination treatment versus 82 (74.5%) of 110 patients receiving monotherapy (risk difference 5.3%; 95% confidence interval (CI), –5.95–16.48). Secondary endpoints, including mortality and adverse events, were similar in the two groups except for persistent bacteremia at day 3, which was less common in the combination arm. In a prespecified interim analysis, the independent committee recommended stopping recruitment for futility prior to meeting the planned randomization of 366 patients. Cloxacillin plus fosfomycin did not achieve better treatment success at day 7 of therapy than cloxacillin alone in MSSA bacteremia. Further trials should consider the intrinsic heterogeneity of the infection by using a more personalized approach. ClinicalTrials.gov registration: NCT03959345.

A meta-analysis for the efficacy and safety of icotinib combined with radiotherapy in treating brain metastases of non-small cell lung cancer.

Currently, the therapies for brain metastases of non-small cell lung cancer (NSCLC) mainly include whole brain radiotherapy and icotinib. For exploring the efficacy and safety of radiotherapy and icotinib, a meta-analysis was performed based on a series of data. A systematic search was performed on PubMed, Web of Science, Cochrane Library, China National Knowledge Infrastructure and Wanfang Database. The search time was set from the database establishment to December, 2022. All randomized controlled trials evaluating the efficacy and safety of whole brain radiotherapy alone or in combination with icotinib for whole brain metastases of NSCLC were included in our meta-analysis. Clinical outcomes and adverse reactions were analyzed using Stata17.0 software. Finally, 10 clinical studies were enrolled in this meta-analysis, including 717 patients. Briefly, compared with radiotherapy alone, icotinib combined with radiotherapy increased response rate [relative ratio (RR) = 1.240; 95% confidence interval (CI) (1.141, 1.348); P < .001] and disease control rate (RR = 1.240, 95% CI [1.141,1.348], P < .001). Besides, according to the outcomes of adverse reaction assessment exhibited, there were no significant differences between the 2 group patients in the incidence of rash (RR = 1.536, 95% CI [0.694, 3.402], P = .290), adverse reaction in gastrointestinal tract (RR = 1.060, 95% CI [0.792, 1.419], P = 1.419), hepatic injury (RR = 1.541, 95% CI [0.798,2.975], P = .198) and leukopenia (RR = 1.182, 95% CI [0.787, 1.777], P = .421). However, the patients receiving combination treatment showed much longer progression free survival than those receiving radiotherapy alone (standardized mean difference = 1.559; 95% CI [0.699, 2.419]; P < .001). Icotinib combined with radiotherapy can significantly short-term and long-term efficacy of NSCLC patients with brain metastases but not increase adverse reactions.

Determinants of the effectiveness of bezafibrate combined with ursodeoxycholic acid in patients with primary biliary cholangitis.

For patients with primary biliary cholangitis (PBC) exhibiting suboptimal responses to ursodeoxycholic acid (UDCA), obeticholic acid (OCA), and bezafibrate (BZF) are currently used and shown to improve long-term outcomes. Nevertheless, we encounter patients who die or undergo liver transplantation (LT) even with combination treatment. In this study, we explored prognostic indicators in patients receiving combination treatment of UDCA and BZF. We took advantage of the Japanese PBC registry and enrolled patients who received both UDCA and BZF therapy in 2000 or later. The covariates investigated included baseline covariates as well as treatment covariates. Two main outcomes (all-cause death or LT and liver-related death or LT) were assessed using multivariable-adjusted Cox proportional hazards models. In total, 772 patients were included. The median follow-up was 7.1years. Using the Cox regression model, bilirubin (hazard ratio [HR] 6.85, 95% confidence interval [CI] 1.73-27.1, p=0.006), alkaline phosphatase (HR 5.46, 95% CI 1.32-22.6, p=0.019), and histological stage (HR 4.87, 95% CI 1.16-20.5, p=0.031) were found associated with LT-free survival. For survival free from liver disease-related death or LT, albumin (HR 7.72, 95% CI 1.48-40.4, p=0.016) and bilirubin (HR 14.5, 95% CI 2.37-88.5, p=0.004) were found significantly associated. In patients with PBC receiving combination therapy, prognostic variables were similar to those in patients receiving UDCA monotherapy. These results indicate the importance of diagnosing patients with PBC at an earlier stage because of the reduced effectiveness of BZF at advanced stages.

Brain metastasis from colorectal cancer: Treatment, survival, and prognosis.

To investigate the clinical characteristics, survival, prognostic factors, and treatment of brain metastasis (BM) from colorectal cancer (CRC). Twenty-one patients with BM from CRC were retrospectively reviewed. Predictive factors for BM and prognostic factors after the diagnosis of BM were examined by univariate and multivariate COX analysis. The time from the development of extracranial metastases, including lung, bone, and liver, to the occurrence of BM was recorded separately. The median overall survival time was 7 months. In univariate prognostic analysis, median survival with multimodal therapy was better than that with unimodal therapy (10 months vs 3 months, P = .000). In addition, median survival with Karnofsky performance status (KPS) < 70, 1 BM lesion, primary tumor stage of II-III, extracranial lesions < 2, and no extracranial metastasis were much better than the other groups (P < .05 of all). Although there was not a significant difference in median survival between patients receiving combination treatment with bevacizumab and those who did not, treatment with bevacizumab was associated with better survival (10 months vs 5 months, P = .436). The time intervals from bone, liver, and lung metastases to BM were 3, 6.5, and 11 months, respectively. Based on multivariate Cox analysis, KPS and treatment modalities were independent prognosis factors (P = .039 and P = .000, respectively). CRC patients with a high KPS and multimodal treatment have improved survival.

Carbepenam resistance prevalence in north India

Background: We investigated the clinical consequences of healthcare-associated bacteremia in light of rising antimicrobial resistance and limited therapy choices for carbapenem-resistant bacteremia. Methods: Between March 2020 and March 2022, a retrospective observational study of carbapenem-resistant Gram-negative bacteremia was conducted at a tertiary care hospital in North India. Results: Patients in our study spent an average of 11.76 days in the intensive care unit (ICU), with a mean time to bacteremia of 6.4 days following admission. Klebsiella pneumoniae was the most prevalent pathogen (44 percent). Patients receiving combination treatment had a reduced death rate (44.8%) than those receiving colistin monotherapy (66.6%) (P = 0.35). Conclusion: Carbapenem resistant bacteremia is a late-onset illness that affects patients who have been exposed to antibiotics in the ICU and has a 60 percent mortality rate after 30 days.

Efficacy and Safety of TACE Combined With Lenvatinib Plus PD-1 Inhibitors Compared With TACE Alone for Unresectable Hepatocellular Carcinoma Patients: A Prospective Cohort Study.

PurposeTo compare the efficacy and safety of the combination of transcatheter arterial chemoembolization (TACE), Lenvatinib, and programmed cell death protein-1 (PD-1) inhibitors (combination group) with TACE (TACE group) in the treatment of patients with unresectable hepatocellular carcinoma (uHCC).MethodsWe consecutively enrolled 110 patients with uHCC in this prospective cohort study, with 56 patients receiving combination treatment and 54 patients receiving TACE from November 2017 to September 2020. The differences in tumor response, survival benefit, and adverse events (AEs) were compared between the two groups. Factors affecting survival were identified via Cox regression analysis.ResultsCompared with the TACE group, the combination group had a higher objective response rate (ORR) (67.9% vs. 29.6%, p < 0.001), longer median progression-free survival (mPFS) (11.9 vs. 6.9 months, P = 0.003) and overall survival (mOS) (23.9 vs. 15.3 months, p < 0.001). Multivariate analysis showed that the neutrophil-to-lymphocyte ratio (NLR) and the treatment option were independent factors associated with the PFS and OS. Further subgroup analysis showed that patients with low NLR (≤median 3.11) receiving combination therapy had better mPFS (20.1 vs. 6.2 months, P < 0.001) and mOS (28.9 vs. 15.2 months, P < 0.001) than those receiving TACE, while no obvious difference in PFS or OS was observed between the two groups in patients with high NLR (> 3.11). There were no unexpected toxicities in the combination group.ConclusionCompared with TACE, the combination treatment demonstrated an improved clinical efficacy and manageable safety profile in patients with uHCC. Combination treatment showed better therapeutic efficacy in patients with low NLR; therefore, this ratio could be used to identify patients who will benefit from this treatment.

Efficacy and tolerability of combination treatment of topiramate and greater occipital nerve block versus topiramate monotherapy for the preventive treatment of chronic migraine: A randomized controlled trial.

To compare the efficacy and tolerability of combination treatment of topiramate and greater occipital nerve block to topiramate monotherapy in adult chronic migraine patients. Options for the preventive treatment of chronic migraine are limited and costly. Combination treatments do not have an evidence base yet. This was a parallel group, 3 arms with 1:1:1 allocation ratio randomized controlled study in consecutive adult chronic migraine patients attending Headache Clinic in a tertiary care hospital. Patients received either topiramate monotherapy 100 mg/day (group A), or topiramate plus greater occipital nerve block with 40 mg lidocaine (2%) and 80mg (2 ml) methylprednisolone as the first injection followed by monthly injections of lidocaine for the next 2 months (group B) or topiramate plus greater occipital nerve block with 40 mg lidocaine (2%) injections monthly for 3 months (group C). The primary endpoint was the mean change in monthly migraine days at Month 3. Multiple secondary endpoints were assessed that included among others, achievement of ≥50% reduction in mean monthly headache days compared to baseline at Month 3 and assessment for any adverse events. One hundred and twenty-five patients were randomized; 41 to group A, 44 to group B, and 40 to group C. Efficacy assessments were done for 121 patients. Patients receiving combination treatment of topiramate and greater occipital nerve block with steroids and lidocaine and greater occipital nerve block with only lidocaine compared to topiramate monotherapy showed greater reductions in monthly migraine days at Month 3 (-9.6 vs -7.3 days; p = 0.003) and (-10.1 vs -7.3 days; p < 0.001) respectively. Greater proportion of patients in both the combination treatment groups (added greater occipital nerve block with and without steroid) achieved ≥50% reduction in mean monthly headache days [71.4% vs 39%; OR (95% CI) 3.9(1.6-9.8); p = 0.004] and [62.4% vs 39%; OR (95% CI) 2.7(1.1-6.7); p = 0.034] respectively, compared to those receiving topiramate monotherapy. Adverse effects between the groups were comparable although patients receiving combination treatment with added greater occipital nerve block reported transient adverse effects like post-injection dizziness, local site swelling, and pain. No serious adverse event was reported. Combination treatments of topiramate with monthly injections of greater occipital nerve block were more effective in reducing monthly migraine days in chronic migraine than topiramate monotherapy at Month 3. Combination treatments were well tolerated.

Differentiation between immune checkpoint inhibitor-related and radiation pneumonitis in lung cancer by CT radiomics and machine learning.

PurposeConsolidation immunotherapy after completion of chemoradiotherapy has become the standard of care for unresectable locally advanced non‐small cell lung cancer and can induce potentially severe and life‐threatening adverse events, including both immune checkpoint inhibitor‐related pneumonitis (CIP) and radiation pneumonitis (RP), which are very challenging for radiologists to diagnose. Differentiating between CIP and RP has significant implications for clinical management such as the treatments for pneumonitis and the decision to continue or restart immunotherapy. The purpose of this study is to differentiate between CIP and RP by a CT radiomics approach.MethodsWe retrospectively collected the CT images and clinical information of patients with pneumonitis who received immune checkpoint inhibitor (ICI) only (n = 28), radiotherapy (RT) only (n = 31), and ICI+RT (n = 14). Three kinds of radiomic features (intensity histogram, gray‐level co‐occurrence matrix [GLCM] based, and bag‐of‐words [BoW] features) were extracted from CT images, which characterize tissue texture at different scales. Classification models, including logistic regression, random forest, and linear SVM, were first developed and tested in patients who received ICI or RT only with 10‐fold cross‐validation and further tested in patients who received ICI+RT using clinicians’ diagnosis as a reference.ResultsUsing 10‐fold cross‐validation, the classification models built on the intensity histogram features, GLCM‐based features, and BoW features achieved an area under curve (AUC) of 0.765, 0.848, and 0.937, respectively. The best model was then applied to the patients receiving combination treatment, achieving an AUC of 0.896.ConclusionsThis study demonstrates the promising potential of radiomic analysis of CT images for differentiating between CIP and RP in lung cancer, which could be a useful tool to attribute the cause of pneumonitis in patients who receive both ICI and RT.

Diferelin® as an effective chemical castration agent for patients with prostate cancer

Androgen deprivation therapy (ADT) is one of the main treatments for patients with locally advanced and metastatic prostate cancer. ADT decreases the level of testosterone. Despite the development of new effective drugs in recent years, luteinizing gonadotropin-releasing hormone agonists are frequently administered as ADT. One of the most commonly used first-line drugs is triptorelin (Diferelin®). In Russia, patients usually receive slow-release triptorelin administered once every month or every 3 months (intramuscular injections) and once every 3 months (subcutaneous injections); the result of using different dosage forms is comparable. Triptorelin effectively keeps serum testosterone level below 20 ng/dL, thereby increasing the time to development of castration-resistant prostate cancer, overall survival of patients receiving combination treatment with radiotherapy, and reduces the severity of symptoms from the lower urinary tract. Triptorelin has a good safety profile and is generally well tolerated by patients.

Severity of constipation related to palonosetron during first-line chemotherapy: a retrospective observational study.

Palonosetron, a long-acting 5-HT3 receptor antagonist, is an effective antiemetic agent for chemotherapy-induced nausea and vomiting; however, it sometimes causes severe constipation. The aim of the present study was to evaluate the severity of palonosetron-related constipation. We retrospectively analyzed the incidence and severity of constipation after intravenous administration of 0.75-mg palonosetron in 150 chemotherapy-naïve patients who received first-line chemotherapy at Saga University Hospital. Constipation was classified into grades 1-5 according to the Common Terminology Criteria for Adverse Events version 5.0. Multiple logistic regression analysis was performed to identify factors associated with palonosetron-related worsening of constipation to grade 2 or higher. Palonosetron significantly increased the incidence and severity of constipation (incidence: before vs. after palonosetron, 35.4% vs. 74.0%, p < 0.0001, and severity: before vs. after palonosetron, 26.7% and 8.7% in grades 1 and 2, respectively, vs. 46.7%, 23.3%, and 4.0% in grades 1, 2, and 3, respectively, p < 0.0001). Despite the use of laxatives, 4.0% of patients had grade 3 constipation requiring manual evacuation. Combination treatment with aprepitant (odds ratio (OR), 10.9; 95% confidence interval (CI), 1.3-90.0; p = 0.026) and older age (OR, 1.25; 95% CI, 1.01-1.57; p = 0.039) were factors associated with the severity of constipation. Constipation was more severe in patients receiving combination treatment with aprepitant than in those treated with palonosetron alone. Older age was also associated with increased risk of severe palonosetron-related constipation. Identification of risk factors can help target risk-based laxative therapy.

Impact of bone mineral density in reducing fracture risk in patients receiving alendronate plus alfacalcidol therapy

BackgroudChanges in bone mineral density (BMD) are a potential surrogate marker for fracture endpoints in clinical trials. However little is known whether the increase in BMD in response to combination treatment with alendronate plus alfacalcidol is associated with fracture risk reduction. We aimed to evaluate the impact of BMD on fracture risk in osteoporosis patients, using the data from the randomized clinical trial comparing alendronate plus alfacalcidol with alendronate alone. MethodsWe selected 412 patients with two or more prevalent vertebral fractures and who had BMD measurements at baseline and after 6, 12, and/or 24 months out of 2022 patients from the database of the Japanese Osteoporosis Intervention Trial. Patients in this subset who received combination treatment with alendronate plus alfacalcidol had shown a lower risk of fracture than patients treated with alendronate alone. We used Poisson regression model analysis to calculate the proportion of treatment effect (PTE) that was attributable to BMD increases in patients receiving combination treatment. ResultsThe highest PTE attributable to changes in BMD was 1.2% in patients with a BMD increase of 3% or more in the lumbar spine. For BMD measurements of the radius, the highest PTE was 2.8% with a BMD increase of 0% or more. For BMD measurements of the metacarpal bone, the highest PTE was 1.2% with a BMD increase of 3% or more. In patients with a BMD greater than or equal to 70% of the young adult mean in the lumbar spine, the PTE attributable to BMD was 0.2%. In patients with a BMD greater than or equal to 70% of the young adult mean in the radius, the PTE attributable to BMD was 0.3%. ConclusionsThe additional effects of alfacalcidol in reducing fracture risk do not likely result from increased BMD; other mechanisms remain a possibility.

Emergency Combination of Four Drugs for Bloodstream Infection Caused by Carbapenem-Resistant Enterobacteriaceae in Severe Agranulocytosis Patients with Hematologic Malignancies after Hematopoietic Stem Cell Transplantation.

Bloodstream infection (BSI) caused by multidrug-resistant (MDR) bacteria or extensively drug-resistant (XDR) bacteria is a global threat. However, an effective treatment regimen is still controversial and inadequate due to the rapid deterioration caused by the bacteria. In immunocompromised and neutropenic patients, MDR-BSI is an emergency, which causes treatment-related mortality. In this study, four agranulocytosis patients with hematologic malignancies after HSCT receiving treatment for carbapenem-resistant Enterobacteriaceae- (CRE-) BSI were included. Conventional treatment using two to three combined antibiotics was administered in the first and second patients. Combination treatment using four drugs, polymyxin B, high-dose tigecycline, fosfomycin, and double-dose carbapenem, was administered in the third and fourth patients. None of the patients receiving conventional treatment survived. Both patients receiving combination treatment using four drugs survived. Therefore, four-drug combination therapy may be needed in CRE-BSI patients who experienced severe agranulocytosis after HSCT. The efficacy of the four-drug combination treatment for CRE-BSI patients as well as the adverse effects need to be further studied.

Plasma MCP-1 levels in bipolar depression during cyclooxygenase-2 inhibitor combination treatment

BackgroundNeuroinflammation plays a role in the pathophysiology of Bipolar Disorder Depression (BDD) and altered levels of inflammatory mediators, such as monocyte chemoattractant protein-1 (MCP-1, aka CCL2) have been reported. This study reports specifically on MCP-1 levels, as a potential marker of BDD and/or treatment response in patients receiving combination treatment with the cyclooxygenase-2 inhibitor, celecoxib (CBX). MethodsIn this randomized, 10-week, double-blind, two-arm, placebo-controlled study, 47 patients with treatment resistant BDD received either escitalopram (ESC) + CBX, or ESC + placebo (PBO). Plasma MCP-1 levels were measured at 3 time points in the BDD subjects, and in a healthy control (HC) group. Depression severity was quantified using the Hamilton Depression Scale (HAMD-17). ResultsThe CBX group had significantly lower HAMD-17 scores vs. PBO at week 4 (P = 0.026) and week 8 (P = 0.002). MCP-1 levels were not significantly different in BDD vs. HC subjects at baseline (P = 0.588), nor in CBX vs. PBO groups at week 8 (P = 0.929). Week 8 HAMD-17 scores and MCP-1 levels were significantly negatively correlated in treatment non-responders to CBX or PBO (P = 0.050). Non-responders had significantly lower MCP-1 levels vs. responders at weeks 4 (P = 0.049) and 8 (P = 0.014). MCP-1 was positively correlated with pro-inflammatory analytes in the PBO group and with anti-inflammatory analytes in the CBX group. ConclusionsCombination treatment reduced treatment resistance and augmented antidepressant response. Baseline plasma MCP-1 levels were not altered in BDD patients. Since non-responders had lower levels of MCP-1, elevated MCP-1 may indicate a better response to CBX + SSRI treatment.

Randomised controlled trial of a comprehensive protocol for preventing constipation following total hip arthroplasty.

To evaluate the efficacy and safety of a comprehensive protocol for constipation prevention. Constipation is a common problem for patients undergoing total hip arthroplasty (THA), yet sparse evidence is available to guide constipation prevention after THA. Randomised controlled superiority clinical trial. This randomised controlled study was carried out according to the Consolidated Standards of Reporting Trials (CONSORT). A total of 80 THA patients were randomised to receive only preoperative education about lifestyle or the combination of education with postoperative abdominal massage and polyethylene glycol 4,000 (Forlax®). Efficacy outcomes included rates of postoperative constipation and enema rescue, as well as time to first postoperative defecation and readmission within 30days. Safety outcomes were number and type of adverse events. Patients who received combination treatment showed a significantly lower rate of postoperative constipation during hospitalisation than patients who received only preoperative education (25% versus 55%), and they showed a significantly lower rate of enema rescue (12.5% versus 40%). Many more patients receiving combination treatment experienced their first defecation within two postoperative days than patients who received only preoperative education (62.5% versus 35.9%). In contrast, the two groups were similar in terms of constipation rate on postoperative days 15 and 30, rate of readmission within 30days and rate of postoperative adverse events. These results suggest that our comprehensive protocol can relieve constipation after THA, reduce the need for enema rescue and shorten time to first defecation without sacrificing safety. More work is needed to optimise and develop this protocol further. Constipation is a distressing problem that frequently occurs after THA. This study confirmed that a comprehensive protocol including preoperative education, postoperative abdominal massage and polyethylene glycol 4,000 can effectively relieve constipation after THA without sacrificing safety.

HIGH-RESOLUTION ANORECTAL MANOMETRY IN TESTING ANORECTAL FUNCTION AFTER COMBINATION TREATMENT FOR RECTAL CANCER

The purpose of the study was to evaluate anorectal function with high-resolution anorectal manometry in patients receiving combination treatment for rectal cancer. Material and methods. We analyzed literature data (PubMed, Scopus, eLIBRARY databases) and our treatment outcomes in 50 rectal cancer patients receiving combination or surgical treatment at Rostov Research Institute of Oncology. Results. The mean anal resting pressure was 1.8 times lower, and the maximal anal squeeze pressure was 1.5 times lower in patients after combination treatment, compared to surgical treatment (p&lt;0.05). 3 months after combination treatment with prolonged radiotherapy, contractile properties of the internal sphincter were decreased in 83.3%, of the external sphincter - in 26.7% of patients. Fatigue rate of external sphincter muscles was increased in 17 (56.7%) patients of this group. We observed a correlation between some anorectal manometry data and the LARS score: in both groups, patients with the maximal LARS score showed the lowest mean anal resting pressure, compared to patients with minimal and average LaRs scores (p&lt;0.05). Conclusion. Due to negative effect of radiation therapy on the anorectal function, careful selection of patients who will benefit from radiation therapy is very important, as well as identification of patients with a high risk of radiation-induced functional problems and development of rehabilitation programs for patients treated for rectal cancer.

Cervicocranialgia: rationale for and evaluation of the clinical efficiency of therapy with the Russian generics of dexketoprofen and tolperisone

Objective: to comparatively evaluate the clinical efficiency of cervicocranialgia therapy with dexketoprofen (flamadex) and tolperisone (calmyrex), as well as with their combination. Patients and methods. The investigation enrolled 90 patients aged 30–60 years with cervicocranialgia, who were randomized into three equal groups. Group 1 included 7 men and 23 women who took dexketoprofen; Group 2 consisted of 13 men and 17 women who were prescribed dexketoprofen and tolperisone; Group 3 comprised 18 men and 12 women who used tolperisone. The three patient groups underwent assessment of the intensity of pain on a visual analogue scale and the degree of muscle tone on a 3-point scale and evaluation of the efficiency of therapy and the hemodynamic effect of the drugs in the common carotid and vertebral arteries. Results and discussion. In all the groups, their treatment reversed neck pain, headache, and dizziness, normalized muscle tone, and improved hemodynamics in the carotid and vertebral arteries. The effect was more pronounced in patients receiving combination treatment (Group 2). The therapy showed a high safety and a good tolerability. Conclusion. Dexketoprofen and tolperisone have been demonstrated to be effective and safe in treating cervicocranialgia.

Pasireotide and Pegvisomant Combination Treatment in Acromegaly Resistant to Second-Line Therapies: A Longitudinal Study.

The treatment of acromegaly resistant to first- and second-line therapies can be extremely challenging. We have described six patients who were successfully treated with a combination therapy of pasireotide and pegvisomant and compared them with a control group of patients resistant to conventional somatostatin analogs (SSAs), whose disease was controlled with other treatment, such as pasireotide (as monotherapy) or pegvisomant (as monotherapy or combined with conventional SSAs). In these six patients, acromegaly was controlled with combined pasireotide and pegvisomant treatment after failure of all other treatments. Compared with the 49 patients in the control group, these six patients had giant and invasive pituitary adenomas (at both the cavernous sinus and other structures). Although not statistically significant, higher growth hormone levels, more elevated Ki-67 expression, greater somatostatin receptor (SSTR) subtype 5 expression, and lower SSTR subtype 2 expression at the diagnosis of acromegaly were detected in patients receiving combination treatment with pasireotide and pegvisomant compared with the control group. Our data have reinforced the importance of personalized treatment of patients with acromegaly according to the clinical, biochemical, molecular, and morphological disease markers and suggest that combined treatment with pasireotide and pegvisomant can induce disease control in tumors with low SSTR2 expression, resistant to conventional SSAs (alone or combined with pegvisomant) and to new-generation SSAs alone (pasireotide).
