[The 505th case: refractory ascites and monoclonal immunoglobulin].

A 52-year-old woman was admitted with a primary complaint of abdominal distension and increased abdominal circumference for more than half a year. There was no evidence of infection or solid tumor on abdominocentesis or laparoscopic surgery. Concurrently, smoldering multiple myeloma was diagnosed. Due to refractory ascites and portal hypertension, a transjugular intrahepatic portosystemic shunt was performed, but the efficacy was not satisfactory. As the anemia progressed, she was finally diagnosed with active multiple myeloma after monoclonal plasma cells were detected in the ascites by flow cytometry. Treated with a triplet regimen that included bortezomib, cyclophosphamide, and dexamethasone (BCD), she achieved a very good partial response and ascites regressed.

[Efficacy of allogeneic hematopoietic stem cell transplantation based on a total body irradiation conditioning treatment regimen for adult acute lymphocytic leukemia].

Objective: To analyze the efficacy of allo-HSCT with total body irradiation (TBI) and chemotherapy alone in the treatment of adult ALL and to explore the factors affecting prognosis. Methods: The clinical data of 95 adult patients with ALL who underwent allo-HSCT from January 2015 to August 2022 were included. According to the conditioning regimen, the patients were divided into two groups: the TBI plus cyclophosphamide (TBI/Cy) group (n=53) and the busulfan plus cyclophosphamide (Bu/Cy) group (n=42). Hematopoietic reconstitution after transplantation, GVHD, transplantation-related complications, relapse rate (RR), non-relapse mortality (NRM), OS, and LFS were compared, and the factors related to prognosis were analyzed. Results: The median time of neutrophil engraftment was 14 (10-25) days in the TBI/Cy group and 14 (10-24) days in the Bu/Cy group (P=0.106). The median time of megakaryocyte engraftment was 17 (10-42) days in the TBI/Cy group and 19 (11-42) days in the Bu/Cy group (P=0.488). The incidence of grade Ⅱ-Ⅳ acute GVHD (aGVHD) in the TBI/Cy and Bu/Cy groups was 41.5% and 35.7%, respectively (P=0.565). The incidence of grade Ⅲ-Ⅳ aGVHD in these two groups was 24.5% and 4.8%, respectively (P=0.009). The incidence of severe chronic GVHD in the two groups was 16.7% and 13.5%, respectively (P=0.689). The incidence of cytomegalovirus infection, Epstein-Barr virus infection, severe infection, and hemorrhagic cystitis in the two groups was 41.5% and 35.7% (P=0.565), 34.0% and 35.7% (P=0.859), 43.4% and 33.3% (P=0.318), and 20.8% and 50.0% (P=0.003), respectively. The median follow-up time was 37.1 months and 53.3 months in the TBI/Cy and Bu/Cy groups, respectively. The 2-year cumulative RR was 17.0% in the TBI/Cy group and 42.9% in the Bu/Cy group (P=0.017). The 2-year cumulative NRM was 24.5% and 7.1%, respectively (P=0.120). The 2-year LFS was 58.5% and 50.0%, respectively (P=0.466). The 2-year OS rate was 69.8% and 64.3%, respectively (P=0.697). In the multivariate analysis, the conditioning regimen containing TBI was a protective factor for relapse after transplantation (HR=0.304, 95% CI 0.135-0.688, P=0.004), whereas the effect on NRM was not significant (HR=1.393, 95% CI 0.355-5.462, P=0.634). Infection was an independent risk factor for OS after allo-HSCT in adult patients with ALL. Conclusion: allo-HSCT based on TBI conditioning regimen had lower relapse rate and lower incidence of hemorrhagic cystitis for adult ALL, compared with chemotherapy regimen. While the incidence o grade Ⅲ/Ⅳ aGVHD was hgher in TBI conditioning regimen than that in chemotherapy regimen.

Prevalence of anticipatory nausea and vomiting in breast cancer patients undergoing highly emetogenic chemotherapy.

OBJECTIVE: Anticipatory nausea and vomiting are unpleasant symptoms observed before undergoing chemotherapy sessions. Less is known about the occurrence of symptoms since the advent of the new neurokinin-1 antagonist. METHODS: This prospective cohort study was performed at a single Brazilian Institution. This study included breast cancer patients who received doxorubicin and cyclophosphamide chemotherapy and an appropriate antiemetic regimen (dexamethasone 10 mg, palonosetron 0.56 mg, and netupitant 300 mg in the D1 followed by dexamethasone 10 mg 12/12 h in D2 and D4). Patients used a diary to record nausea, vomiting, and use of rescue medication in the first two cycles of treatment. The prevalence of anticipatory nausea and vomiting was assessed before chemotherapy on day 1 of C2. RESULTS: From August 4, 2020, to August 12, 2021, 60 patients were screened, and 52 patients were enrolled. The mean age was 50.8 (28-69) years, most had stage III (53.8%), and most received chemotherapy with curative intent (94%). During the first cycle, the frequency of overall nausea and vomiting was 67.31%, and that of severe nausea and vomiting (defined as grade>4 on a 10-point visual scale or use of rescue medication) was 55.77%. Ten patients had anticipatory nausea and vomiting (19.23%). The occurrence of nausea and vomiting during C1 was the only statistically significant predictor of anticipatory nausea and vomiting (OR=16, 95%CI 2.4-670.9, p=0.0003). CONCLUSION: The prevalence of anticipatory nausea is still high in the era of neurokinin-1 antagonists, and failure of antiemetic control in C1 remains the main risk factor. All efforts should be made to control chemotherapy-induced nausea or nausea and vomiting on C1 to avoid anticipatory nausea.

Protective effect of coenzyme Q10 in cyclophosphamide-induced kidney damage in rats.

OBJECTIVE: We aimed to investigate the effect of coenzyme q10 on cyclophosphamide-induced kidney damage in rats. METHODS: A total of 30 female Wistar-Albino rats were utilized to form three groups. In group 1 (control group) (n=10), no drugs were given. In group 2 (cyclophosphamide group) (n=10), 30 mg/kg intraperitoneal cyclophosphamide was administered for 7 days. In group 3 (cyclophosphamide+coenzyme q10 group) (n=10), 30 mg/kg cyclophosphamide and 10 mg/kg coenzyme q10 were given for 7 days via intraperitoneal route. Right kidneys were removed in all groups. Blood malondialdehyde levels and activities of catalase and superoxide dismutase were measured. Histopathological damage was evaluated by examining the slides prepared from kidney tissue using a light microscope. RESULTS: Tissue damage was significantly higher in the cyclophosphamide group than in the cyclophosphamide+coenzyme q10 group (p<0.05). The malondialdehyde levels were significantly higher and the activities of superoxide dismutase and catalase were lower in the cyclophosphamide group than in the cyclophosphamide+coenzyme q10 group (p<0.05). CONCLUSION: Coenzyme q10 may be a good option to prevent cyclophosphamide-induced kidney damage.

Determination of genoprotection against cyclophosphamide induced toxicity in bone marrow of Swiss albino mice by Moringa oleifera leaves and Tinospora cordifolia stem.

The present study aimed to determine the genoprotective activity and safety of Moringa oleifera leave and Tinospora cordifolia stem extracts against cyclophosphamide (CP)-induced genotoxicity utilizing Swiss albino mice. Animals were divided into 14 groups for subacute treatment with either M. oleifera or T. cordifolia extracts daily for 28 days. The extract doses selected were 100, 200 or 400 mg/kg b.w administered orally alone or combined with CP (50 mg/kg b.w. intraperitoneally daily for 5 days). Analyses performed included the comet assay, micronucleus test (MN) in bone marrow cells and sperm head abnormality assay (SHA). M. oleifera and T. cordifolia extracts induced no significant genotoxic effects on somatic and germ cells. In contrast, for all cells examined M. oleifera and T. cordifolia extracts inhibited DNA damage initiated by CP. Taken together data demonstrated that both plant extracts did not exhibit marked genotoxic effects but displayed potential chemoprotective properties against CP-induced genotoxicity in Swiss mice.

[Ameliorative effect of rare ginsenosides on reproductive injury induced by cyclophosphamide in female rats: based on metabonomics].

Objective: To investigate the effect of rare ginsenosides (RGS) on reproductive injury induced by cyclophosphamide (CP) in female rats. Methods: Twenty-four female rats were divided into four groups [normal control (NC), RGS, CP, and CP+RGS group] with 6 rats in each group. CP group (the model group) and CP+RGS group (the treatment group) were intraperitoneally injected with CP 30 mg/kg for 5 days for modeling, and CP+RGS group was given RGS intragastric intervention. General growth status of rats in each group was observed, the organ index was calculated, and the pathological changes of ovary, uterus, liver and kidney were observed by hematoxylin-eosin staining. Serum levels of estradiol, follicle stimulating hormone (FSH), luteinizing hormone (LH), pro-inflammatory factors interleukin (IL) 6, IL-1ß, tumor necrosis factor-α were detected. The urine samples were collected after RGS treatment for metabonomics analysis. Metabolomic profiling based on ultra performance liquid chromatography (UPLC) coupled with mass spectrometry (MS) was used to analyze and determine the urine metabolites of rats in each group. Results: Compared with NC group, the ovary index of CP group [(0.054±0.015) %] was significantly decreased (P<0.05), the uterus index [(0.293±0.036) %] and estradiol level [(62.9±6.4) pmol/L] were significantly decreased (all P<0.01), serum levels of FSH, LH, IL-6 and IL-1ß [(20.4±1.0) U/L, (29.0±3.0) U/L, (185.4±28.6) ng/L, (72.9±2.0) ng/L, respectively] were significantly increased (all P<0.01). Compared with CP group, the ovary index in CP+RGS group [(0.075±0.010) %] was significantly increased (P<0.05), serum estradiol level [(122.1±16.2) pmol/L] was significantly increased (P<0.01), serum FSH, IL-1ß and IL-6 levels [(16.7±1.0) U/L, (111.8±17.4) ng/L, (60.1±2.2) ng/L, respectively] were significantly decreased (all P<0.01). Metabonomics analysis results showed that, a total of 352 metabolites were detected in urine, of which 12 were found to be potential markers associated with reproductive injury according to the screening standard. After treatment with RGS, differential metabolites were improved in the direction of NC group. Pathway enrichment suggests that the therapeutic effect of RGS was related to multiple metabolic pathways, including purine metabolism and taurine and hypotaurine metabolism. Conclusion: RGS might reduce inflammation and thus ameliorate the damage caused by CP to the reproductive system of female rats by affecting purine metabolism and other pathways.

Effect of Flavonols of Aronia melanocarpa Fruits on Morphofunctional State of Immunocompetent Organs of Rats under Cyclophosphamide-Induced Immunosuppression.

Aronia melanocarpa berries contain many compounds with potential benefits for human health. The food flavonoids quercetin and rutin, found in significant amounts in the fruits of A. melanocarpa, are known to have favourable effects on animal and human organisms. However, data on the effect of flavonols isolated from black chokeberry on immune functions during immunosuppression are not available in the literature. Thus, the aim of this study was to evaluate the effect of flavonol fraction isolated from A. melanocarpa fruits, in comparison with pure quercetin and rutin substances, on the dysfunctional state of rat thymus and spleen in immunodeficiency. The study was performed on Wistar rats. The animals were orally administered solutions of the investigated substances for 7 days: water, a mixture of quercetin and rutin and flavonol fraction of A. melanocarpa. For induction of immunosuppression, the animals were injected once intraperitoneally with cyclophosphamide. Substance administration was then continued for another 7 days. The results showed that under the influence of flavonols, there was a decrease in cyclophosphamide-mediated reaction of lipid peroxidation enhancement and stimulation of proliferation of lymphocytes of thymus and spleen in rats. At that, the effect of the flavonol fraction of aronia was more pronounced.

Position statement of the Brazilian society of Rheumatology on mesna use as a preventive therapy for bladder disease in patients with systemic autoimmune diseases and systemic vasculitis under cyclophosphamide treatment.

OBJECTIVE: To review current literature to support the use of mesna as a preventive therapy for hemorrhagic cystitis and bladder cancer in patients with systemic autoimmune diseases and systemic vasculitis treated with cyclophosphamide. MATERIALS AND METHODS: The search for articles was conducted systematically through MEDLINE, LILACS, Cochrane Library, and Embase databases. Only articles in English were selected. For available records, titles and abstracts were selected independently by two investigators. RESULTS: Eighteen studies were selected for analysis. The known adverse effects of cyclophosphamide were hematological toxicity, infections, gonadal toxicity, teratogenicity, increased risk for malignancy and hemorrhagic cystitis. Long-term toxicity was highly dependent on cyclophosphamide cumulative dose. The risk of bladder cancer is especially higher in long-term exposure and with cumulative doses above 36 g. The risk remains high for years after drug discontinuation. Hemorrhagic cystitis is highly correlated with cumulative dose and its incidence ranges between 12 and 41%, but it seems to be lower with new regimens with reduced cyclophosphamide dose. No randomized controlled trials were found to analyze the use of mesna in systemic autoimmune rheumatic diseases and systemic vasculitis. Retrospective studies yielded conflicting results. Uncontrolled prospective studies with positive results were considered at high risk of bias. No evidence was found to support the use of mesna during the treatment with cyclophosphamide for autoimmune diseases or systemic vasculitis to prevent hemorrhagic cystitis and bladder cancer. In the scenarios of high cumulative cyclophosphamide dose (i.e., > 30 g), patients with restricted fluid intake, neurogenic bladder, therapy with oral anticoagulants, and chronic kidney disease, mesna could be considered. CONCLUSION: The current evidence was found to be insufficient to support the routine use of mesna for the prophylaxis of hemorrhagic cystitis and bladder cancer in patients being treated for systemic autoimmune diseases and systemic vasculitis with cyclophosphamide. The use may be considered for selected cases.

[Antioxidative effect of wheat-grain moxibustion on cyclophosphamide-induced liver injury in mice based on Nrf2-Keap1 signaling pathway].

OBJECTIVE: To observe the protective effect of wheat-grain moxibustion on cyclophosphamide (CTX)-induced liver injury in mice, and explore its mechanism based on the nuclear factor E2-related factor 2 (Nrf2)-Kelch-like ECH-associated protein 1 (Keap1) signaling pathway. METHODS: Twenty-four male CD-1 (ICR) mice were randomly divided into a blank group, a model group, and a moxibustion group, with 8 mice in each group. The mice in the model group and the moxibustion group were intraperitoneally injected with CTX (80 mg/kg) to induce liver injury. The mice in the moxibustion group were treated with wheat-grain moxibustion at "Guanyuan" (CV 4) and bilateral "Zusanli" (ST 36) and "Sanyinjiao" (SP 6), with each acupoint being treated by 3 cones, approximately 30 seconds per cone, once daily for 7 days. After intervention, the general condition of the mice was observed; the liver mass was measured and the liver index was calculated; HE staining was used to observe the morphology of the liver, and the liver tissue pathological score was assessed; ELISA was used to detect the serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), glutamate dehydrogenase (GLDH) and the levels of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) in the liver; Western blot and real-time fluorescence quantitative PCR were used to detect the protein and mRNA expression of Nrf2, Keap1, and quinione acceptor oxidoreductase 1 (NQO1) in the liver. RESULTS: Compared with the blank group, the mice in the model group showed sluggishness, unsteady gait, and decreased body weight; liver index was increased (P<0.01); liver cells were loosely arranged, with a small number of cell swollen and exhibiting balloon-like changes; liver tissue pathological score was increased (P<0.05); the serum levels of AST, ALT, GLDH, and level of MDA in the liver were increased (P<0.05), and the levels of SOD and GSH-Px in the liver were decreased (P<0.05); protein and mRNA expression of Nrf2 and NQO1 in the liver was decreased (P<0.01), protein and mRNA expression of Keap1 in the liver was increased (P<0.01). Compared with the model group, the mice in the moxibustion group showed improvement in general condition; liver index was decreased (P<0.01); liver cell structure was relatively intact and clear, and liver tissue pathological score was decreased (P<0.05); the serum levels of AST, ALT, GLDH, and level of MDA in the liver were decreased (P<0.05), and the levels of SOD and GSH-Px in the liver were increased (P<0.05, P<0.01); protein and mRNA expression of Nrf2 and NQO1 in the liver was increased (P<0.05), protein and mRNA expression of Keap1 in the liver was decreased (P<0.05). CONCLUSION: The wheat-grain moxibustion may alleviate CTX-induced liver injury by activating the Nrf2-Keap1 signaling pathway and enhancing the expression of antioxidative enzyme system in the body.

Mycophenolate mofetil vs. cyclophosphamide-based induction regimens for lupus nephritis: Outcomes at a tertiary care centre in Lahore, Pakistan.

Objectives: To compare the efficacy of mycophenolate mofetil with intravenous cyclophosphamideas induction therapy in lupus nephritis. METHODS: The observational, prospecrive, cohort study was conducted at the Rheumatology Department of Fatima Memorial Hospital, Lahore, Pakistan, from July 2016 to June 2019, and comprised lupus nephritis patients. For induction therapy, the patients were assigned at the discretion of the treating rheumatologist to mycophenolate mofetil group MMF, and intravenous cyclophosphamide group CYC. The latter group was further divided into NIH subgroup that received the therapy as per the protocol of the National Institutes of Health, and ELNT subgroup which recived the therapy as per the Euro Lupus Nephritis Trial protocol. Maintenance therapy in all groups was mycophenolate mofetil. Tacrolimus was added in case of non-response. The outcome was the achievement of complete renal response at 6, 12 and 24 months. Data was analysed using SPSS 26. RESULTS: Of the 131 patients, 126(96.2%) were females. The overall mean age was 27±7.7 years. There were 58(44.2%) patients in group MMF and 73(55.7%) in group CYC, which had subgroup NIH 46(63%) and subgrpup ELNT 27(37%). The complete renal response rates at 6, 12, and 24 months were 22 (43.1%), 35 (71.4%), and 40(83.3%) for group MMF; 5(12.5%), 9(22%) and 24 (58.5%) for subgroup NIH, and 6(26.1%), 8(36.4%) and 14(63.6%) for subgroup ELNT. Group MMF outcomes were significantly better than the rest (p<0.05). CONCLUSIONS: Mycophenolate mofetil induction therapy was more effective than intraveenous cyclophosphamide in terms of achieving remission at 6, 12 and 24 months.

Semimethylation is a feature of diffuse large B-cell lymphoma, and subgroups with poor prognosis are characterized by global hypomethylation and short telomere length.

BACKGROUND: Large B-cell lymphoma (LBCL) is the most common lymphoma and is known to be a biologically heterogeneous disease regarding genetic, phenotypic, and clinical features. Although the prognosis is good, one-third has a primary refractory or relapsing disease which underscores the importance of developing predictive biological markers capable of identifying high- and low-risk patients. DNA methylation (DNAm) and telomere maintenance alterations are hallmarks of cancer and aging. Both these alterations may contribute to the heterogeneity of the disease, and potentially influence the prognosis of LBCL. RESULTS: We studied the DNAm profiles (Infinium MethylationEPIC BeadChip) and relative telomere lengths (RTL) with qPCR of 93 LBCL cases: Diffuse large B-cell lymphoma not otherwise specified (DLBCL, n = 66), High-grade B-cell lymphoma (n = 7), Primary CNS lymphoma (n = 8), and transformation of indolent B-cell lymphoma (n = 12). There was a substantial methylation heterogeneity in DLBCL and other LBCL entities compared to normal cells and other B-cell neoplasms. LBCL cases had a particularly aberrant semimethylated pattern (0.15 ≤ ß ≤ 0.8) with large intertumor variation and overall low hypermethylation (ß > 0.8). DNAm patterns could not be used to distinguish between germinal center B-cell-like (GC) and non-GC DLBCL cases. In cases treated with R-CHOP-like regimens, a high percentage of global hypomethylation (ß < 0.15) was in multivariable analysis associated with worse disease-specific survival (DSS) (HR 6.920, 95% CI 1.499-31.943) and progression-free survival (PFS) (HR 4.923, 95% CI 1.286-18.849) in DLBCL and with worse DSS (HR 5.147, 95% CI 1.239-21.388) in LBCL. These cases with a high percentage of global hypomethylation also had a higher degree of CpG island methylation, including islands in promoter-associated regions, than the cases with less hypomethylation. Additionally, telomere length was heterogenous in LBCL, with a subset of the DLBCL-GC cases accounting for the longest RTL. Short RTL was independently associated with worse DSS (HR 6.011, 95% CI 1.319-27.397) and PFS (HR 4.689, 95% CI 1.102-19.963) in LBCL treated with R-CHOP-like regimens. CONCLUSION: We hypothesize that subclones with high global hypomethylation and hypermethylated CpG islands could have advantages in tumor progression, e.g. by inactivating tumor suppressor genes or promoting treatment resistance. Our findings suggest that cases with high global hypomethylation and thus poor prognosis could be candidates for alternative treatment regimens including hypomethylating drugs.

Efficacy and safety of netupitant/palonosetron in preventing nausea and vomiting in diffuse large B cell lymphoma patients undergoing R-CHOP chemotherapy.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma, for which cyclophosphamide, doxorubicin, vincristine, and prednisone with rituximab(R-CHOP) is one of the standard regimens. Given that R-CHOP is highly emetogenic, chemotherapy-induced nausea and vomiting (CINV) prevention is clinically important. However, there is a paucity of studies focusing on these patients. This study aimed to ascertain the effectiveness of an oral fixed-dose combination of netupitant and palonosetron (NEPA) in preventing CINV in patients with DLBCL undergoing first-line R-CHOP chemotherapy. Seventy patients were enrolled in this single-center prospective non-comparative study conducted between November 2020 and May 2023 in South Korea. NEPA was administered 1 h prior to chemotherapy initiation on day 1. The primary endpoint of the study was the complete response rate (no emesis, and no rescue medication) during the acute, delayed, and overall phases, which were assessed over a period of 120 h post-chemotherapy. The complete response rates for NEPA were 90.0% [95% CI 80.5, 95.9] for the acute phase, 85.7% [95% CI 75.3, 92.9] for the delayed phase, and 84.3% [95% CI 73.6, 91.9] for the overall phase, with no-emesis rates (acute: 97.1% [95% CI 97.1, 99.7], delayed: 95.7% [95% CI 88.0, 99.1], overall: 92.9% [95% CI 84.1, 97.6]). NEPA was well tolerated with no severe treatment-emergent adverse events. NEPA exhibited substantial efficacy in mitigating CINV in DLBCL patients undergoing R-CHOP chemotherapy, demonstrating high CR and no-emesis rates, and favorable safety profiles.

Diffuse Large B-Cell Lymphoma With Cardiac Invasion Presented as Acute Myocardial Infarction and Left Ventricular Hypertrophy: A Case Report.

Primary cardiac lymphoma is an exceedingly rare malignant tumor, with diffuse large B-cell lymphoma (DLBCL) being the most prevalent histological subtype. This disease has non-specific clinical manifestations, making early diagnosis crucial. However, DLBCL diagnosis is commonly delayed, and its prognosis is typically poor. Herein, we report the case of a 51-year-old male patient with DLBCL who presented with recurrent chest tightness for 4 months as the primary clinical symptom. The patient was admitted to the hospital and diagnosed with acute myocardial infarction and left ventricular hypertrophy with heart failure. Echocardiography revealed a progression from left ventricular thickening to local pericardial thickening and adhesion in the inferior and lateral walls of the left ventricle. Finally, pathological analysis of myocardial biopsy confirmed the diagnosis of DLBCL. After treatment with the R-CHOP chemotherapy regimen, the patient's chest tightness improved, and he was discharged. After 2 months, the patient succumbed to death owing to sudden ventricular tachycardia, ventricular fibrillation, and decreased blood pressure despite rescue efforts. Transthoracic echocardiography is inevitable for the early diagnosis of DLBCL, as it can narrow the differential and guide further investigations and interventions, thereby improving the survival of these patients.

Yogurt Alleviates Cyclophosphamide-Induced Immunosuppression in Mice through D-Lactate.

Numerous studies have investigated the immunomodulatory effects of yogurt, but the underlying mechanism remained elusive. This study aimed to elucidate the alleviating properties of yogurt on immunosuppression and proposed the underlying mechanism was related to the metabolite D-lactate. In the healthy mice, we validated the safety of daily yogurt consumption (600 µL) or D-lactate (300 mg/kg). In immunosuppressed mice induced by cyclophosphamide (CTX), we evaluated the immune regulation of yogurt and D-lactate. The result showed that yogurt restored body weight, boosted immune organ index, repaired splenic tissue, recovered the severity of delayed-type hypersensitivity reactions and increased serum cytokines (IgA, IgG, IL-6, IFN-γ). Additionally, yogurt enhanced intestinal immune function by restoring the intestinal barrier and upregulating the abundance of Bifidobacterium and Lactobacillus. Further studies showed that D-lactate alleviated immunosuppression in mice mainly by promoting cellular immunity. D-lactate recovered body weight and organ development, elevated serum cytokines (IgA, IgG, IL-6, IFN-γ), enhanced splenic lymphocyte proliferation and increased the mRNA level of T-bet in splenic lymphocyte to bolster Th1 differentiation. Finally, CTX is a chemotherapeutic drug, thus, the application of yogurt and D-lactate in the tumor-bearing mouse model was initially explored. The results showed that both yogurt (600 µL) and D-lactate (300 mg/kg) reduced cyclophosphamide-induced immunosuppression without promoting tumor growth. Overall, this study evaluated the safety, immune efficacy and applicability of yogurt and D-lactate in regulating immunosuppression. It emphasized the potential of yogurt as a functional food for immune regulation, with D-lactate playing a crucial role in its immunomodulatory effects.

Symptomatic adverse events of chemotherapy in breast cancer patients:Using CTCAE, PRO-CTCAE, and EORTC QLQ-C30.

BACKGROUND: The Common Terminology Criteria for Adverse Events (CTCAE) is used as a tool to evaluate the adverse events (AE) of chemotherapy in cancer patients. Since CTCAE by medical providers underestimates AE more than patient-reported outcomes (PRO), the National Cancer Institute developed PRO-CTCAE. The present study investigated differences between symptoms detected using CTCAE by medical providers and PRO-CTCAE by breast cancer patients. METHODS: Patients received chemotherapy comprising epirubicin and cyclophosphamide pre- or postoperatively. AE were evaluated using 4 questionnaires:PRO-CTCAE, CTCAE, the European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire (EORTC-QLQ-30), and Hospital Anxiety and Depression Scale (HADS) after 1, 2, and 3 courses of chemotherapy. RESULTS: Forty-two patients were registered. Regarding the recognition of psychological symptoms, such as fatigue, anxiety, and discouragement, and subjective symptoms, including heart palpitations and shortness of breath, PRO using PRO-CTCAE was significantly higher than medical provider-recognized outcomes using CTCAE. Concerning the recognition of regimen-specific symptoms, such as vomiting, nausea, and decreased appetite, medical provider- recognized outcomes were the same or higher than PRO. In QLQ-C30, the physical and role functions, fatigue and dyspnea significantly worsened after 2 and 3 courses of chemotherapy. J. Med. Invest. 71 : 82-91, February, 2024.

Evaluation of some proinflammatory cytokines and biochemical parameters in pre and postmenopausal breast cancer women.

The study was planned to evaluate the differences in certain proinflammatory cytokines(IL-6, TNF-α) with CRP and biochemical parameters (E2, D3, LDH, GGT, TSB, Ca, Ph, uric acid), between women with pre- and postmenopausal breast cancer and seemingly healthy women in Iraqi women as controls; at medical city in teaching Oncology hospital,70 breast cancer patients women their ages ranged (47.51 ± 1.18) and 20 healthy women with age (44.45 ± 2.66) begun from September (2020) to February (2021). The aims of this study to investigate the evaluation of chemotherapy effects especially doxorubicin and cyclophosphamide only use in this study in pre and postmenopausal breast cancer women on proinflammatory cytokines(IL-6, TNF-α) with CRP and on biochemical parameters(E2, D3, LDH, GGT, TSB, Ca, Ph, uric acid) in pre and postmenapausal breast cancer women. The patients were divided into five groups and each group contains 14 patients women with breast cancer during pre and postmenopausal periods. The control groups were divided into 10 pre and 10 postmenopausal women(Fig. 1). The results of proinflammatory cytokines of and biochemical parameters in premenopausal groups were as the levels of IL-6 (pg/ml),TNF-α(pg/ml) and CRP (ng/ml) showed significant increase differences (P < 0.01)among breast cancer treated (BCT) groups in comparison with control groups,While the Liver enzymes GGT,LDH and TSB showed highly significant increase (P < 0.01) in BCT groups, Estrogen levels (pg/ml) and D3(ng/ml) increased significantly (P < 0.01)among BCT groups.

Ibrutinib combined with immunochemotherapy with or without autologous stem-cell transplantation versus immunochemotherapy and autologous stem-cell transplantation in previously untreated patients with mantle cell lymphoma (TRIANGLE): a three-arm, randomised, open-label, phase 3 superiority trial of the European Mantle Cell Lymphoma Network.

BACKGROUND: Adding ibrutinib to standard immunochemotherapy might improve outcomes and challenge autologous stem-cell transplantation (ASCT) in younger (aged 65 years or younger) mantle cell lymphoma patients. This trial aimed to investigate whether the addition of ibrutinib results in a superior clinical outcome compared with the pre-trial immunochemotherapy standard with ASCT or an ibrutinib-containing treatment without ASCT. We also investigated whether standard treatment with ASCT is superior to a treatment adding ibrutinib but without ASCT. METHODS: The open-label, randomised, three-arm, parallel-group, superiority TRIANGLE trial was performed in 165 secondary or tertiary clinical centres in 13 European countries and Israel. Patients with previously untreated, stage II-IV mantle cell lymphoma, aged 18-65 years and suitable for ASCT were randomly assigned 1:1:1 to control group A or experimental groups A+I or I, stratified by study group and mantle cell lymphoma international prognostic index risk groups. Treatment in group A consisted of six alternating cycles of R-CHOP (intravenous rituximab 375 mg/m2 on day 0 or 1, intravenous cyclophosphamide 750 mg/m2 on day 1, intravenous doxorubicin 50 mg/m2 on day 1, intravenous vincristine 1·4 mg/m2 on day 1, and oral prednisone 100 mg on days 1-5) and R-DHAP (or R-DHAOx, intravenous rituximab 375 mg/m2 on day 0 or 1, intravenous or oral dexamethasone 40 mg on days 1-4, intravenous cytarabine 2 × 2 g/m2 for 3 h every 12 h on day 2, and intravenous cisplatin 100 mg/m2 over 24 h on day 1 or alternatively intravenous oxaliplatin 130 mg/m2 on day 1) followed by ASCT. In group A+I, ibrutinib (560 mg orally each day) was added on days 1-19 of R-CHOP cycles and as fixed-duration maintenance (560 mg orally each day for 2 years) after ASCT. In group I, ibrutinib was given the same way as in group A+I, but ASCT was omitted. Three pairwise one-sided log-rank tests for the primary outcome of failure-free survival were statistically monitored. The primary analysis was done by intention-to-treat. Adverse events were evaluated by treatment period among patients who started the respective treatment. This ongoing trial is registered with ClinicalTrials.gov, NCT02858258. FINDINGS: Between July 29, 2016 and Dec 28, 2020, 870 patients (662 men, 208 women) were randomly assigned to group A (n=288), group A+I (n=292), and group I (n=290). After 31 months median follow-up, group A+I was superior to group A with 3-year failure-free survival of 88% (95% CI 84-92) versus 72% (67-79; hazard ratio 0·52 [one-sided 98·3% CI 0-0·86]; one-sided p=0·0008). Superiority of group A over group I was not shown with 3-year failure-free survival 72% (67-79) versus 86% (82-91; hazard ratio 1·77 [one-sided 98·3% CI 0-3·76]; one-sided p=0·9979). The comparison of group A+I versus group I is ongoing. There were no relevant differences in grade 3-5 adverse events during induction or ASCT between patients treated with R-CHOP/R-DHAP or ibrutinib combined with R-CHOP/R-DHAP. During maintenance or follow-up, substantially more grade 3-5 haematological adverse events and infections were reported after ASCT plus ibrutinib (group A+I; haematological: 114 [50%] of 231 patients; infections: 58 [25%] of 231; fatal infections: two [1%] of 231) compared with ibrutinib only (group I; haematological: 74 [28%] of 269; infections: 52 [19%] of 269; fatal infections: two [1%] of 269) or after ASCT (group A; haematological: 51 [21%] of 238; infections: 32 [13%] of 238; fatal infections: three [1%] of 238). INTERPRETATION: Adding ibrutinib to first-line treatment resulted in superior efficacy in younger mantle cell lymphoma patients with increased toxicity when given after ASCT. Adding ibrutinib during induction and as maintenance should be part of first-line treatment of younger mantle cell lymphoma patients. Whether ASCT adds to an ibrutinib-containing regimen is not yet determined. FUNDING: Janssen and Leukemia & Lymphoma Society.
