RESUMO

Background: The objective is to evaluate the prevalence of acute kidney injury (AKI) as an early complication of the percutaneous nephrolithotomy (PCNL) procedure. Materials and Methods: From May 2022 to October 2022, we conducted a retrospective study on patients undergoing PCNL procedures in two of the tertiary medical centers affiliated with Isfahan University of Medical Sciences. Patients' baseline characteristics, laboratory values, perioperative data, and stone features were documented. AKI was defined either as a ≥0.3 mg/dL increase in the serum creatinine level within 2 days, or a ≥1.5-fold increase in baseline serum creatinine level within 7 days after the operation. Laboratory values were measured 1 day before PCNL and daily thereafter until discharge. Patients were followed 1 week later to detect all of the possible cases of AKI. Results: The final analysis was performed on 347 individuals. AKI developed in 16 (4.61%) cases. The two groups were comparable regarding age (P = 0.887), gender (P = 0.566), and underlying comorbidities including diabetes mellitus (P = 0.577) and hypertension (P = 0.383). The mean body mass index (BMI) (P < 0.001) and both frequency and severity of hydronephrosis (P < 0.001) were significantly different. A higher mean PCNL duration (P < 0.001), period of hospitalization (P < 0.001), and blood loss volume (P < 0.001) were observed in those who developed AKI. Overall, 56.3% (9) of patients in the AKI group and 2.7% (9) in the non-AKI group required the establishment of more than one access tract, during the procedure (P < 0.001). A lower preoperative hemoglobin level was observed in the AKI group (P < 0.001). Those with AKI had significantly larger stones (3.08 ± 0.46 vs. 2.41 ± 0.23 cm, P < 0.001) and higher Hounsfield units (P < 0.001). In addition, in the AKI group, most of the calculi (81.3%, 13) were of staghorn type, whereas in the non-AKI group, calculi were most frequently located in the middle calyx (30.2%, 100), (P < 0.001). Conclusion: The prevalence of post-PCNL AKI is approximately 4.61%. The mean BMI, preoperative hemoglobin level, PCNL duration, intraoperative blood loss volume, and hospitalization period were significantly higher among patients who developed AKI. Those with AKI had significantly larger stones with higher Hounsfield units and more frequently of staghorn type. The two groups were not statistically different regarding age, gender, and presence of comorbidities (hypertension and diabetes mellitus).

RESUMO

PURPOSE: The current candidate gene association study aims to investigate tag SNPs from the TACR1 gene as pharmacogenetic predictors of response to the antiemetic guidelines-recommended, NK-1 receptor antagonist-based, triple antiemetic regimens. METHODS: A set of eighteen tag SNPs of TACR1 were genotyped in breast cancer patients receiving anthracycline and cyclophosphamide (with/without docetaxel) applying real-time PCR-HRMA. Data analysis for 121 ultimately enrolled patients was initiated by defining haplotype blocks using PHASE v.2.1. The association of each tag SNP and haplotype alleles with failure to achieve the defined antiemetic regimen efficacy endpoints was tested using PLINK (v.1.9 and v.1.07, respectively) based on the logistic regression, adjusting for the previously known chemotherapy-induced nausea and vomiting (CINV) prognostic factors. All reported p-values were corrected using the permutation test (n = 100,000). RESULTS: Four variants of rs881, rs17010730, rs727156, and rs3755462, as well as haplotypes containing the mentioned variants, were significantly associated with failure to achieve at least one of the defined efficacy endpoints. Variant annotation via in-silico studies revealed that the non-seed sequence variant, rs881, is located in the miRNA (hsa-miR-613) binding site. The other three variants or a variant in complete linkage disequilibrium with them overlap a region of high H3K9ac-promoter-like signature or regions of high enhancer-like signature in the brain or gastrointestinal tissue. CONCLUSION: Playing an essential role in regulating TACR1 expression, gene polymorphisms of TACR1 serve as the potential pharmacogenetic predictors of response to the NK-1 receptor antagonist-based, triple antiemetic regimens. If clinically approved, modifying the NK-1 receptor antagonist dose leads to better management of CINV in risk-allele carriers.

RESUMO

MicroRNAs (miRs) play a crucial role in the leukemogenesis and the prognosis of acute myeloid leukemia (AML). This study investigated the therapeutic effects of resveratrol, gallic acid, and piperine as natural anticancer agents on the HL-60 cell line and their roles in apoptosis. In this experimental study, quantitative analysis of miRs, including miR-17, miR-92b, miR-181a, and miR-222, were performed in 150 newly diagnosed patients with AML by real-time PCR assay. HL-60 cell viability as well as the expression of miRs, BAX, BCL-2, MCL-1, WT1, c-Kit, and CEBPA, were also assessed after transfection with the LNA-miRs and treatment with resveratrol, gallic acid, and piperine. The expression of miR-17 and miR-181a decreased significantly in LNA-anti-miRs. Although HL-60 cell viability decreased in LNA-anti-miR-222, miR-17, and miR-92b, blockade of miR-181a increased the cell viability. Besides, the cell viability increased merely in the piperine-treated group. Compared to untreated cells, miR-17 and miR-92b expression significantly increased in gallic acid- and resveratrol-treated cells. In HL-60 cells treated with resveratrol, gallic acid, and piperine, the expression of miR-181a was also increased significantly. The expression of BAX was also increased in resveratrol and piperine-treated groups. Compared to untreated cells, the expression of c-Kit increased significantly in the piperine-treated group; however, it decreased in the resveratrol-treated group. LNA-anti-miRs may be a promising agent for the treatment of AML. All three compounds used in this study showed anticancer effects, which can exert the desired outcome in patients with AML.

RESUMO

BACKGROUND: Gemcitabine is a chemotherapeutic agent, widely used for the treatment of many types of cancer. Cytidine deaminase (CDA) enzyme plays an important role in the metabolism of gemcitabine. This study aimed to assess the power of serum CDA residual activity in predicting drug efficacy and toxicity in gemcitabine-treated cancer patients. METHODS: This prospective observational study enrolled 63 patients with different types of malignancies who received gemcitabine chemotherapy between May 2019 and January 2022. Blood samples were obtained before the initiation of chemotherapy and serum CDA residual activity was determined using a modification of the Berthelot assay. The patients were followed up for at least 12 months up to 41 months. Overall survival was recorded and treatment-related toxicities were documented according to National Cancer Institute Common Terminology Criteria. RESULTS: Kaplan-Meier analysis showed that patients with a lower than median CDA value (≤ 8.06 U/mg protein) had a significantly longer survival compared to patients with higher CDA values (> 8.06 U/mg, P ˂ 0.005). Among several potentially involved factors, a significant association between CDA activity and overall survival was observed in univariate analysis (HR = 4.219, 95% CI 1.40-12.74, P = 0.011). On the other hand, the rate of anemia was significantly higher in low-CDA patients compared to high-CDA individuals (P < 0.05). CONCLUSION: These findings suggest that CDA activity could be a promising biomarker to predict survival and the occurrence of anemia in cancer patients treated with gemcitabine.

RESUMO

BACKGROUND: Colorectal cancer is one of the most common cancers in the world, with about one million cases diagnosed annually. Various treatment methods can be used to treat colorectal cancer, including chemotherapy with different drug regimens. Considering the need to opt for more effective and less expensive drugs in the treatment of this disease, the present study aimed to compare the cost-effectiveness of FOLFOX6+Bevacizumab with FOLFOX6+Cetuximab in patients with stage IV colorectal cancer referred to medical centers in Shiraz, Iran, in 2021. MATERIALS AND METHODS: Using a decision tree, the cost-effectiveness and cost-utility of the 2 drug regimens were compared in all studied patients through the census method. Having a societal perspective, this study considered direct medical costs, direct non-medical costs, and indirect costs. The effectiveness indicators included the rate of major response to the drug combination used and the Quality-adjusted Life Year (QALY). The data were analyzed using Treeage 2011 and Excel 2016 software. In order to ensure the robustness of the results, one-way and probabilistic sensitivity analyses were performed as well. RESULTS: The results showed that the expected costs, the effectiveness (major response rate), and the QALYs of the FOLFOX6+Bevacizumab drug regimen were $16746.13(USD), .49, and .19, respectively, and those of the FOLFOX6+Cetuximab regimen were, respectively, $15191.05 (USD), .68, and .22. Therefore, FOLFOX6+Cetuximab compared to FOLFOX6+Bevacizumab was less costly and more effective and had a greater QALY, thus being considered as the dominant option. Also, the results of the sensitivity analyses showed that there was a bit of uncertainty. CONCLUSION: Considering that the FOLFOX6+Cetuximab regimen was more cost-effective, it is suggested to be prioritized in preparing clinical guidelines for Iranian colorectal cancer patients. In addition, increasing the basic and supplementary insurance coverage for this drug combination as well as the use of remote technology to guide patients by oncologists can be solutions to reduce direct and indirect costs of the patients.

RESUMO

Background: Circulating microRNAs (miRNAs) can help to predict the chemotherapy response in breast cancer with promising results. The aim of the present study was to investigate the relationships between the miR-199a, miR-663a, and miR-663b expression and chemotherapy response in metastatic breast cancer patients. Methods: This study is a case-control study performed at Yasuj University of Medical Sciences (2018-2021). The expression levels of miR-663a, miR-663b, and miR-199a in the serum of 25 patients with metastatic breast cancer versus 15 healthy individuals were determined by the real-time polymerase chain reaction method. The response to treatment was followed up in a 24-month period. All patients were treated with second-line medications. Two or more combinations of these drugs were used: gemcitabine, Navelbine®, Diphereline®, Xeloda®, letrozole, Aromasin®, and Zolena®. Statistical analyses were performed in SPSS 21.0 and GraphPad Prism 6 software. The expression levels were presented as mean±SD and analyzed by Student's t test. Results: The results and clinicopathological features of patients were analyzed by t test. The statistical analysis showed that miR-663a expression was related to human epidermal growth factor receptor 2 (HER2) status and was significantly lower in the HER2+ than HER2- group (P=0.027). Moreover, the expression of miR-199a and miR-663b was significantly correlated with the response to treatment, in which the expression of miR-199a was higher in the poor-response group (P=0.049), while the higher expression of miR-663b was seen in the good-response group (P=0.009). Conclusion: These findings state that the high plasma level of miR-199a and the low plasma level of miR-663b may be related to chemoresistance in patients with metastatic breast cancer.

RESUMO

Background: Blood loss of postoperative after prostate surgery could be related with an increase in urinary fibrinolytic activity. Tranexamic acid (TXA) is both a potent inhibitor of plasminogen and urokinase activators and a low molecular weight substance that is excreted unchanged in the urinary tract and can be administered both orally and intravenously. This study aimed to evaluate the effectiveness TXA administration in reducing bleeding in benign prostatic hyperplasia (BPH) patients who underwent open prostatectomy. Materials and Methods: This double-blind randomized clinical trial was conducted on patients with BPH who underwent open prostatectomy. The first group received TXA (1 gr IV from during surgery to 48 h after surgery, 3 times/day). Twenty-four hours after surgery, the two groups were compared in terms of bleeding rate. Hemoglobin (Hb), hematocrit (HCT), and platelet (Plt) counts were also assessed before and after the intervention. Results: Intervention and control groups were comparable in terms of basic and baseline values of variables at the beginning of the study (P > 0.05). The mean bleeding volume in TXA group was significantly lower than the control group 112.11 ± 53.5 and 190.00 ± 97.5 CC; P ≤ 0.001). Mean hospitalization (3.28±0.46 vs. 4.38 ± 0.95 days P < 0.001) and surgery duration (98.11 ± 37.11 vs. 128.00 ± 39.12 h; P = 0.001) were significantly lower in TXA group compared to control intervention. Conclusion: According to the findings of the current study, the administration of TXA led to reduce bleeding in BPH patients who underwent open prostatectomy. Furthermore, the mean Hb, HCT, levels were significantly affected by TXA. TXA treatment approach also can reduce the surgery and hospitalization time effectively. TXA approach is recommended as effective procedure in BPH patients who underwent open prostatectomy.

RESUMO

INTRODUCTION AND HYPOTHESIS: Abdominal Sacral Colpopexy (ASC) is one of the best surgical methods to repair apical or uterine prolapse. We aimed to evaluate the short-term results of a triple-compartment open ASC strategy using polyvinylidene fluoride (PVDF) mesh in the treatment of patients with severe apical or uterine prolapse. METHODS: Women with high-grade uterine or apical prolapse with or without cysto-rectocele were prospectively enrolled in the study from April 2015 to June 2021. We performed all-compartment repair using a tailored PVDF mesh for ASC. We assessed the severity of pelvic organ prolapse (POP) using the Pelvic Organ Prolapse Quantification (POP-Q) system at baseline and 12 months after the operation. The patients completed the International Continence Society Questionnaire Vaginal Symptom (ICIQ-VS) questionnaire at baseline, 3, 6, and 12 months postoperatively. RESULTS: Thirty-five women with a mean age of 59.8±10.0 years were included in the final analysis. Stage III and stage IV prolapse was evident in 12 and 25 patients, respectively. After 12 months, the median POP-Q stage was significantly lower compared to the baseline (4 vs 0, p=<0.0001). Vaginal symptoms score was also reduced significantly at 3-month (7.5±3.5), 6-month (7.3±3.6), and 12-month (7.2±3.1) compared to the baseline (39.5±6.7) (p values < 0.0001). We did not observe any mesh extrusion or high-grade complications. Six (16.7%) patients had cystocele recurrence during the 12-month follow-up, and two of them needed reoperation. CONCLUSIONS: Our short-term follow-up showed that using an open ASC technique with PVDF mesh in treating high-grade apical or uterine prolapse is associated with a high rate of procedural success and low rates of complication.

RESUMO

BACKGROUND: Hairy cell leukemia (HCL) is an indolent chronic lymphoproliferative disorder and first-line treatment with either intravenous or subcutaneous cladribine generally leads to long-lasting remissions. METHOD: All 131 patients with hairy-cell leukemia (HCL) were analyzed, with a median follow-up of 91 months. Data is from 2007 to 2020. We evaluated the response rate to cladribine as the first line and the response rate to cladribine with or without rituximab in relapsed patients. Further, we assessed relapse-free survival, complications, and secondary malignancy. RESULTS: After a median follow-up of 91 months, the recurrence rate was 24%. The 5-year and 10-year RFS rates were 85% and 66%, respectively. Adding rituximab to 2-CDA leads to a better response rate than just cladribine (90% vs. 27.3%, p-value = 0.002) in the relapsed patients. CONCLUSION: HCL patients have long-term survival when cladribine is the first line of treatment. Furthermore, adding rituximab to cladribine leads to a higher response rate.

RESUMO

BACKGROUND: Selenium (Se) is a micronutrient, which has recently been proven to have a positive effect on the immune system of cancer patients, but the underlying mechanism is not clearly defined. In this randomized controlled trial, we evaluated the effect of three-month Se supplementation on the profile of CD4+ T-helper subsets including IFN-γ+/IL-4- Th1, IFN-γ-/IL-4+ Th2, and CD4+IL-17+ Th17 cells in sixteen diffuse large B cell lymphoma (DLBCL) patients at stable remission phase who consumed Se (Se+) compared to the fourteen control patients who did not receive Se (Se-). METHODS: The frequency of IFN-γ+/IL-4- Th1, IFN-γ-/IL-4+ Th2, and CD4+IL-17+ Th17 lymphocytes was determined using a four-color flow cytometry method. RESULTS: The results revealed that three-month Se supplementation significantly decreased the proportion of CD4+IL-17+ Th17 lymphocytes but not IFN-γ+/IL-4- Th1 and IFN-γ-/IL-4+ Th2 subtypes in DLBCL patients at stable remission. Change in the percentage of IFN-γ+/IL-4- Th1, IFN-γ-/IL-4+ Th2, and CD4+IL-17+ Th17 cells did not significantly differ between Se+ and Se- groups. No positive correlation was observed between changes in different Th subpopulations in both Se+ and Se- groups. CONCLUSIONS: Taken together, three-month Se supplementation can reduce the proportion of CD4+IL-17+ Th17 cells in DLBCL patients at stable remission phase. Larger population and longer follow-up of patients is necessary to specify the clinical significance of Se supplementation on the popularity of T-helper cells in DLBCL patients.

RESUMO

Objective: The high prevalence of urolithiasis and its recurrence entail the preparation of an efficient drug with the least side effects. Tribulus terrestris, Urtica dioica, Adiantum capillus-veneris, Stigma maydis (corn silk), and Cucumis melo are herbal remedies utilized in traditional medicine for urolithiasis. This study aimed to assess the efficiency of these plants' extracts in treating urolithiasis. Methods: In a randomized, single-blind, placebo-controlled clinical trial, participants meeting inclusion criteria were randomly allocated to the drug (n = 27) and placebo (n = 27) groups to take herbal or placebo solutions, respectively, at a dose of 60 drops 3 times daily for 4 weeks with standard treatment. Before and after the intervention, 24-h urine volume and the quantities of calcium, sodium, citrate, oxalate, urea, creatinine, and uric acid in 24-h urine, and urinary pH were measured. The number and size (diameter in mm) of stones were determined by ultrasonography and recorded for each patient. Findings: Except for 24 h urine volume, other urinary parameters did not alter significantly at the end of the intervention compared to baseline. Furthermore, the two groups had no significant difference regarding these indices. Regarding stone parameters, the stone size decreased significantly in the drug group compared to the placebo group (P = 0.049). The number of cases with complete stone expulsion in the drug group was significantly higher than in the placebo group (12 cases vs. 4 cases, respectively, P = 0.017). Conclusion: Oral consumption of the herbal solution causes stone size reduction and stone expulsion in patients with urolithiasis.

RESUMO

BACKGROUND: Factor V deficiency is a rare bleeding disorder that can be either congenital or acquired. Factor V deficiency mostly present with mucosal bleeding. Coagulation factor V does not increase considerably during normal gestation. Since pregnancy can be threatened by blood clotting disorders, abnormal changes in coagulation factors level can pose challenges to pregnant women. CASE PRESENTATION: We report a 40-year-old pregnant woman with prolonged gingival bleeding and epistaxis at 28 weeks of pregnancy. Her past medical history included two unexplained abortions. Physical examination was unremarkable, but the blood test showed elevated PT and PTT with a considerable decrease in factor V activity, while other factors were within normal range. Subsequently, the patient was diagnosed with congenital factor V deficiency. After treatment with fresh frozen plasma, she underwent vaginal delivery and a baby with factor V deficiency was born. CONCLUSIONS: This is the second report of recurrent miscarriage in congenital factor V deficiency patients. Clinicians should consider the possibility of factor V deficiency in women with a history of idiopathic miscarriage even in patients without any symptoms.

RESUMO

In this paper, the properties of CuInSe2 (CISe) films deposited on three transparent substrates (FTO, FTO/NiOx, FTO/MoO3) are studied. These substrates might be used for bifacial solar cells, in place of the conventional glass/Mo substrates. CISe layers are deposited by spray pyrolysis followed by a selenization process. For the same deposition conditions, the CISe layers on FTO show the largest grain size (~ 0.50 µm) and crystallinity, while FTO/MoO3 substrates result in the smallest grains (~ 0.15 µm). The optical bandgap of the CISe films ranged from 1.35 eV for FTO substrate to 1.44 eV for FTO/MoO3 substrate. All films show p-type conductivity, with the carrier densities of 1.6 × 1017 cm-3, 5.4 × 1017 cm-3, and 2.4 × 1019 cm-3 for FTO, FTO/NiOx, and FTO/MoO3 substrates, respectively. The CISe films also show different conduction, and valence levels, based on the substrate. In all cases, an ohmic behavior is observed between the CISe and substrate. The results demonstrate that CISe layer crystallinity, carrier concentration, mobility, and energy levels are strongly dependent on the chemical nature of the substrate. Bare FTO shows the most appropriate performance in terms of device requirements.

RESUMO

BACKGROUND: Post-chemotherapy cognitive impairment commonly known as 'chemobrain' or 'chemofog' is a well-established clinical disorder affecting various cognitive domains including attention, visuospatial working memory, executive function, etc. Although several studies have confirmed the chemobrain in recent years, scant experiments have evaluated the potential neurotoxicity of different chemotherapy regimens and agents. In this study, we aimed to evaluate the extent of attention deficits, one of the commonly affected cognitive domains, among breast cancer patients treated with different chemotherapy regimens through neuroimaging techniques. METHODS: Breast cancer patients treated with two commonly prescribed chemotherapy regimens, Adriamycin, Cyclophosphamide and Taxol and Taxotere, Adriamycin and Cyclophosphamide, and healthy volunteers were recruited. Near-infrared hemoencephalography and quantitative electroencephalography assessments were recorded for each participant at rest and during task performance to compare the functional cortical changes associated with each chemotherapy regimen. RESULTS: Although no differences were observed in hemoencephalography results across groups, the quantitative electroencephalography analysis revealed increased power of high alpha/low beta in left fronto-centro-parietal regions involved in dorsal and ventral attention networks in the Adriamycin, Cyclophosphamide and Taxol-treated group compared with the Taxotere, Adriamycin and Cyclophosphamide and control group. The Adriamycin, Cyclophosphamide and Taxol-treated cases had the highest current source density values in dorsal attention network and ventral attention network and ventral attention network-related centers in 10 and 15 Hz associated with the lowest Z-scored Fast Fourier Transform coherence in the mentioned regions. CONCLUSIONS: The negatively affected neurocognitive profile in breast cancer patients treated with the Adriamycin, Cyclophosphamide and Taxol regimen proposes presumably neurotoxic sequelae of this chemotherapy regimen as compared with the Taxotere, Adriamycin and Cyclophosphamide regimen.

RESUMO

This study aimed to evaluate the effects of two common chemotherapy regimens on breast cancer (BC) survivors' cognition. The participants comprised 35 patients with BC who underwent two chemotherapy regimens, AC-T and TAC, and 24 matched healthy volunteers. The participants were assessed regarding cognitive function through Addenbrooke's Cognitive Examination and Cambridge Brain Science tests. The results represent the AC-T regimen to be more toxic than the TAC in domains of language, concentration, and visuospatial working memory (P-value = 0.036, 0.008, and 0.031, respectively) and should be prescribed with caution in patients with BC suffering from baseline cognitive impairments.

RESUMO

Background: Previous animal studies have shown a protective effect of 5-phosphodiesterase inhibitors on cancer therapeutics-related cardiac dysfunction (CTRCD) of anthracyclines. Aim: The aim of this study was to evaluate the clinical effect of sildenafil on the primary prevention of CTRCD in human. Materials and Methods: In this randomized double-blind clinical trial, the primary end point was efficacy in preventing the reduction of left ventricular ejection fraction (LVEF). The intervention group patients received sildenafil at a dose of 25 milligrams twice a day before starting the chemotherapeutic regimen, and the control group received placebo. All the patients at baseline and after the 6-month follow-up underwent 4D and speckle-tracking echocardiography and cardiac MRI, accompanied by hs-troponin I and NT-Pro-BNP measurement. Results: Sixty patients were enrolled in this study, and data from 52 patients (24 patients in the intervention group and 28 patients in the control group) were used in the final analysis. Our findings showed that in the intervention and control groups, LVEF was dropped from 61.28 ± 7.36 to 51.57 ± 7.67 (difference (D) = -9.71 ± 11.95, p=0.003) and from 57.9 ± 7.29 to 50.2 ± 7.02% (D = -7.7 ± 5.93; p=0.001), respectively (between-group difference = -2.01%, p=0.26). CTRCD was detected in 11 patients in the control group (42.8%) and 10 in the intervention group (41.6%, p=0.51). Conclusion: Consumption of sildenafil for primary prevention of anthracycline-induced cardiac toxicity seems to be unbeneficial. This trial is registered with IRCT20180506039554N1.

RESUMO

PURPOSE: The current study aimed at investigating the efficacy of aprepitant-containing triple antiemetic regimen in FLOT (fluorouracil + leucovorin + oxaliplatin + docetaxel) recipients as well as the emetogenic potential of FLOT regimen, through comparison of nausea and vomiting rates in a moderately emetogenic chemotherapy, FLOT, and a highly emetogenic chemotherapy recipients. STUDY: Patients planned to receive one of FLOT, FOLFOX (fluorouracil + leucovorin + oxaliplatin/moderate-emetic risk), or TAC (docetaxel + doxorubicin + cyclophosphamide/high-emetic risk) regimens were recruited. All patients were treated with the same triple antiemetic regimen containing aprepitant. RESULTS: A total of 165 chemotherapy-naïve patients (52 FLOT recipients) were eligible to enter the study. At the end of day 5, "complete response" (primary efficacy endpoint) was achieved by 84.6%, 63.5%, and 61.5% of the FLOT-receiving patients in acute, delayed, and overall phases, respectively. A significant difference was seen among the odds of FLOT recipients and FOLFOX recipients concerning "complete response" achievement in delayed (p = 0.014) and overall (p = 0.017) phases, "no emesis" in delayed (p = 0.018) and overall (p = 0.010) phases, and also "complete protection" in acute (p = 0.023), delayed (p = 0.009), and overall (p = 0.006) phases; however, the difference between the odds of FLOT recipients and TAC recipients, in relation to achieving these endpoints, was insignificant. FLOT group showed significantly faster time-to-antiemetic regimen failure and time-to-first emetic episode in comparison with the FOLFOX group, which was insignificant in comparison with the TAC group. CONCLUSION: According to the findings, FLOT has to be considered as a high-emetic-risk regimen; provided that, as recommended by the antiemetic guidelines towards better management of delayed nausea and vomiting induced by highly emetogenic regimens, executing clinical trials concerning the efficacy of continuing dexamethasone on days 2-4 in aprepitant-containing triple antiemetic regimen schedule is required.

RESUMO

INTRODUCTION: Little is known about the expression of immune checkpoint receptors in the peripheral blood of lymphoma patients. Herein, we assessed the expression of inhibitory checkpoint receptors, including CTLA-4, PD-1/PDL-1, LAG-3, and TIM-3 in the peripheral blood of lymphoma patients and its correlation with the clinical outcomes of patients. Therefore, 47 classical Hodgkin lymphoma (cHL), 48 non-Hodgkin lymphoma patients with diffuse large B-cell lymphoma (DLBCL) subtype, and 30 healthy controls were recruited. METHODS: The expression of inhibitory receptors was evaluated using SYBR Green real-time PCR method. RESULTS: CTLA-4, LAG-3, and TIM-3 genes were significantly upregulated in both cHL and DLBCL patients compared to the healthy controls. In addition, the level of these molecules was differentially expressed in cHL and DLBCL patients at different disease phases compared to the healthy controls. The CTLA-4 gene was highly expressed in newly diagnosed (ND) cHL patients compared to the relapsed ones. Relapsed DLBCL patients had significantly increased LAG-3 expression compared to patients at remission, as well as ND patients. Regarding cHL patients, high CTLA-4 expression was correlated with low lactate dehydrogenase level and better performance status, whereas the level of LAG-3 was significantly elevated in patients with poor performance status. Lower initial PD-1 expression was associated with improved disease-free survival in cHL patients. CONCLUSIONS: Inhibitory immune checkpoint receptors are aberrantly expressed in the peripheral blood of cHL and DLBCL patients in which high LAG-3 in DLBCL patients and PD-1/LAG-3 in cHL patients are associated with relapse occurrence and worse prognosis, respectively.

RESUMO

BACKGROUND: The role of T-helper lymphocytes especially T helper 2 (Th2) subsets in lymphoid malignancies is debatable and unknown. METHODS: Herein, we evaluated the polarization of the IFN-γ+/IL-4- Th1 and IFN-γ-/IL-4+ Th2 lymphocytes in 95 lymphoma patients including 47 classical Hodgkin's lymphoma (cHL) and 48 diffuse large B cell lymphoma patients (DLBCL) at different disease phases and its correlation with the clinical outcomes of patients using flow cytometry method. RESULTS: The proportion of IFN-γ+/IL-4- Th1 lymphocytes was significantly higher in cHL patients at remission compared to the newly diagnosed ones. Both cHL and DLBCL patients at remission phase had significantly more IFN-γ-/IL-4+ Th2 lymphocytes than those patients at relapse/refractory phase as well as newly diagnosed ones. Despite having higher frequency of IFN-γ+/IL-4- Th1 lymphocytes, the mean fluorescent intensity (MFI) of IFN-γ was lower in relapsed cHL patients, in those with high-risk IPI score, performance status (PS) ≥2 and B symptom-positive groups compared to their corresponding counterparts in newly diagnosed patients. CONCLUSION: Taken together, higher peripheral blood IFN-γ-/IL-4+ Th2 lymphocytes might be associated with a favorable prognosis like lower rate of relapse in lymphoma patients.
