Predictive factors of developing lupus nephritis in systemic lupus erythematosus

Renal involvement is common in systemic lupus erythematosus (SLE), and even without elevated serum creatinine, there is a high proportion of abnormal urine analysis in these patients. Lupus nephritis (LN) develops early in the course of the disease in 50% of SLE patients, and end stage renal disease (ESRD) occurs in 4.3-10.1%. We performed a keyword-based literature search and included 31 articles published from 2004 to 2023. Ethnic and racial differences may affect LN, including higher incidence of LN in Black, Hispanic and Asian compared with white patients. In addition, male sex, longer disease duration, smoking, low albumin globulin ratio, low complement, anti-double stranded DNA, high anti-Sm is associated with disease progression to LN. High serum creatinine (>1.5 mg/dL) at disease onset is the most commonly reported independent clinical laboratory predictor for ESRD in patients with SLE. Other factors indicating an increased risk for ESRD are higher chronicity index, high systolic blood pressure, black race, male sex, hypocomplementemia, class of LN (III, IV and V) and older age.

Predictive values of sarcopenia and systemic inflammation-based markers in advanced hepatocellular carcinoma after hepatectomy

Sarcopenia accompanied by systemic inflammation is associated with poor prognosis in patients with advanced hepatocellular carcinoma (HCC). However, the effect of sarcopenia combined with systemic inflammation on the prognosis of patients with advanced HCC who underwent hepatectomy is unclear. This study aimed to evaluate the effect of sarcopenia and inflammation on the prognosis of patients with advanced HCC. This retrospective study included 151 patients recruited between July 2010 and December 2022. We defined advanced HCC as that presenting with vascular invasion or tumor size ≥2cm or multiple tumors. Sarcopenia was assessed using the psoas muscle index. Preoperative inflammatory markers were used by calculating the prognostic nutritional index, albumin-globulin ratio (AGR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio. Cox regression analysis was performed to determine the prognostic factors for overall survival. Of 151 patients, sarcopenia occurred in 84 (55.6 %). Sarcopenia was significantly associated with male sex, older age, body mass index (<25kg/m2), and a higher NLR. In the multivariate analysis, AGR <1.25 (hazard ratio [HR], 2.504; 95% confidence interval [CI]: 1.325-4.820; p<0.05); alpha-fetoprotein levels ≥25ng/mL (HR, 1.891; 95% CI: 1.016-3.480; p=0.04); and sarcopenia (HR, 1.908; 95% CI: 1.009-3.776; p<0.05) were independent predictors of overall survival. The sarcopenia and low AGR groups had significantly worse overall survival than either the non-sarcopenia and high AGR or sarcopenia and low AGR groups. Sarcopenia and AGR are independent prognostic factors in patients with advanced HCC. Thus, sarcopenia may achieve a better prognostic value when combined with AGR.

Albumin-Globulin Ratio Is an Independent Prognostic Factor for Gastric Cancer Patients who Received Curative Treatment.

The albumin-globulin ratio (AGR) is a useful biomarker for predicting postoperative complications and a poor prognosis in patients with various types of cancer and can be evaluated without invasive testing or surgery. In this study, we aimed to evaluate the usefulness of the AGR in predicting the short- and long-term prognoses of patients with gastric cancer who underwent radical resection at our institution. This study is a retrospective cohort analysis in which eligible patients were selected from the medical records of patients who underwent radical resection for gastric cancer at Yokohama City University from 2000 to 2020 and their medical records were reviewed. A total of 240 patients with gastric cancer were classified into high-AGR (>1.57) and low-AGR (≤1.57) groups and their overall survival (OS), recurrence-free survival (RFS), and postoperative complication rates were compared. Of the total 240 patients, 87 were classified into the high AGR group and 153 were classified into the low AGR group; the incidence of postoperative complications in the two groups did not differ to a statistically significant extent (34.4% vs. 39.2%, p=0.491). The long-term findings showed that the 5-year OS and RFS rates were significantly better in the high AGR group [84.0% vs. 64.8% (p=0.005), 80.0% vs. 61.9% (p=0.015), respectively]. Preoperative low AGR is a risk factor for OS and DFS in patients with gastric cancer who undergo surgery. The AGR may be a useful biomarker that can be applied as a prognostic indicator for patients with gastric cancer.

Peripheral blood nutrient indices as biomarkers for anti‑PD‑1 therapy efficacy and prognosis in patients with advanced gastric cancer.

Immunotherapy offers survival benefits for patients with advanced gastric cancer, but not all populations can benefit from immunotherapy. Good nutritional status is fundamental to a patient's immune function and may have an impact on the efficacy of immunotherapy. The present study aimed to investigate changes in prognostic nutritional index (PNI), advanced lung cancer inflammation index (ALI) and albumin-globulin ratio (AGR) values before and after immunotherapy in patients with advanced gastric cancer. The study also aimed to determine the potential association of the aforementioned values with patient outcomes and prognosis. Body mass index (BMI), serum albumin, total protein, peripheral blood lymphocyte, neutrophil, carcinoembryonic antigen (CEA), carbohydrate antigen19-9 (CA19-9) and a-fetoprotein (AFP) data were collected from 195 patients with advanced gastric cancer who underwent immunotherapy from January 2020 to October 2021. In addition, PNI, ALI and AGR values were calculated based on variables in blood collected from the patients within 3 days prior to immunotherapy and 3 weeks after immunotherapy. The results demonstrated that low PNI was associated with elevated CEA levels. Moreover, low ALI levels were associated with reduced BMI levels, elevated AFP levels, PD-L1 negative and first-line treatment. Comparison of responding and non-responding groups revealed that patients who responded to immunotherapy had higher PNI and AGR values than patients who did not respond, both before and after treatment, but had lower CEA and CA19-9 levels after treatment. Furthermore, in the non-responding group, PNI and AGR values were decreased and CEA values were increased following treatment compared with those prior to treatment. The objective response and disease control rates were higher in the high PNI and AGR groups compared with the low PNI and AGR groups, respectively. Moreover, PNI and AGR were found to be independent predictors of the short-term efficacy of immunotherapy for advanced gastric cancer, with cut-off values of 47.18 and 1.29, respectively. Univariate analysis revealed that ALI was associated with the progression-free survival (PFS) of patients, while multivariate analysis demonstrated that baseline PNI and AGR were independent predictors of PFS. In conclusion, tumor progression leads to a decline in the nutritional level of patients, and the present study indicated that effective immunotherapy may alleviate this deterioration to a certain extent. Furthermore, PNI and AGR exhibit potential in predicting the efficacy of immunotherapy and the prognosis of patients with advanced gastric cancer, and may exhibit potential as biomarkers in clinical practice.

Albumin-Globulin Ratio Indicates the Survival Outcome of Pancreatic Cancer Cases Who Underwent Preoperative Treatment and Curative Surgical Resection

Background The pretreatment albumin–globulin ratio (AGR) is a frequently used inflammation-associated factor that has been reported to have associations with the survival outcomes of various malignancies. Methods We retrospectively analyzed 162 patients with pancreatic cancer who underwent preoperative treatment followed by curative surgery at Nagoya University Hospital between April 2010 and December 2020. Representative nutritional status indicators of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), prognostic nutritional index (PNI), and albumin–globulin ratio (AGR) were calculated for each case. Results Among pretreatment blood examination parameters, only AGR (cutoff: 1.33) showed a significant difference in overall survival time (OS) and progression-free survival time (PFS) from the beginning of the preoperative treatment. Median PFS was 22.3 mo, in high AGR cases and 17.1 mo, in low AGR cases (P = 0.019). Median OS was 48.7 mo, in high AGR cases and 32.9 mo, in low AGR cases (P = 0.043). Conclusion High pretreatment AGR may be a favorable prognostic factor for pancreatic cancer patients who received preoperative multimodal therapy followed by curative cancer resection. It may imply that nutritional status and inflammation control before the multimodal treatment affect the survival outcomes of pancreatic cancer cases and needs to be optimized.

Clinicopathological Findings in Cats Tested for Feline Immunodeficiency Virus (FIV) and Feline Leukaemia Virus (FeLV)

Abstract This retrospective study aimed to evaluate the clinicopathological changes in a population of cats tested for feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV), in an Italian Veterinary University Hospital, in the period between January 2002 and May 2016. During the period of 14 years, 1834 cats were tested, and of these 241/1834 (13.1%) were positive for FIV antibodies and 92/1834 (5%) cats were positive for FeLV antigen. These data confirm the presence of a high prevalence of these viruses on Italian territory. To the authors’ knowledge, this study describes findings that have never been evaluated before, such as iron status in retrovirus-infected cats and urinalysis in FeLV-positive cats. In this study, FIV-positive cats were more likely to have higher serum protein concentration and lower albumin-globulin ratio than other groups of cats. Lower urine specific gravity and higher urine protein to creatinine ratio were also detected for FIV-positive cats when compared with negative and healthy cats. FeLV-positive cats were more likely to have cytopenia, decreased haemoglobin, haematocrit and RBC compared with other groups of cats. The data obtained underline the importance of considering retroviral infections in the presence of a broad spectrum of risk factors and laboratory anomalies.

Should We Always Perform Preoperative Chest Computed Tomography in Patients with cT1a Renal Cell Carcinoma?

No definitive criteria regarding the performance of preoperative chest computed tomography (CT) in patients with cT1a renal cell carcinoma (RCC) exists. We aimed to establish an objective standard for the optimal timing of preoperative chest CT in patients with RCC. Data from 890 patients who underwent surgical treatment for RCC between January 2011 and December 2020 were retrospectively collected. The primary endpoint was detection of lung metastasis on chest CT before nephrectomy. A multivariable logistic regression model predicting positive chest CT scans was used. Predictors included preoperative cTN stage, presence of systemic symptoms, Charlson comorbidity index (CCI), platelet count/hemoglobin ratio, albumin/globulin ratio (AGR), and De Ritis ratio. The overall rate of positive chest CT scans before nephrectomy was 3.03% (27/890). Only one patient had lung metastasis before surgery for cT1a. cT stage (≥cT1b), CCI ≥4, and low AGR were associated with a higher risk of positive chest CT scans. The best cutoff value for AGR was 1.39. After 890-sample bootstrap validation, the concordance index was 0.80. The net benefit of the proposed strategy was superior to that of the select-all and select-none strategies according to decision curve analysis. Therefore, when chest CT scans were performed with a risk of a positive result ≥10%, 532 (59.8%) negative chest CT scans could be prevented. Only 24 (2.7%) potentially positive chest CT scans were misdiagnosed. Therefore, we recommend chest CT in patients with ≥cT1b disease, CCI ≥4, and low AGR.

The Predictive Significance of Prognostic Nutritional Index and Serum Albumin/Globulin Ratio on the Overall Survival of Penile Cancer Patients Undergoing Penectomy.

Objective: To assess the value of using the prognostic nutritional index (PNI) and serum albumin/globulin ratio (AGR) in predicting the overall survival (OS) of patients with penile cancer (PC) undergoing penectomy. Materials and methods: A retrospective analysis of 123 patients who were admitted to our hospital due to PC from April 2010 to September 2021 and who underwent penectomy were included in the study. The optimal cut-off value of the PNI and AGR was determined by receiver operating characteristic curve analysis. Kaplan–Meier analysis and the Cox proportional hazard model were used to evaluate the correlation between the PNI, AGR, and OS in patients with PC. Results: A total of 16 of the 123 patients died during the follow-up period, and the median follow-up time was 58.0 months. The best cut-off values of the PNI and AGR were set to 49.03 (95% confidence interval 0.705–0.888, Youden index = 0.517, sensitivity = 57.9%, specificity = 93.7%, p < 0.001) and 1.28 (95% confidence interval 0.610–0.860, Youden index = 0.404, sensitivity = 84.1%, specificity = 56.2%, p = 0.003). The Kaplan–Meier analysis showed that the OS of the patients in the high PNI group and the high AGR group was significantly higher than that of the patients in the low PNI group and the low AGR group (p < 0.001). The univariable analysis showed that the aCCI, the clinical N stage, the pathological stage, and the PNI, AGR, SII, and PLR are all predictors of OS in patients with PC (p < 0.05). The multivariable analysis showed that the PNI (risk rate [HR] = 0.091; 95% CI: 0.010–0.853; p = 0.036) and the AGR (risk rate [HR] = 0.171; 95% CI: 0.043–0.680; p = 0.012) are independent prognostic factors for predicting OS in patients with PC undergoing penectomy. Conclusions: Both the PNI score and the serum AGR are independent prognostic factors for predicting OS in patients with PC undergoing penectomy.

Pankreatikoduodenektomili hastalarda albümin/globulin oranının postoperatif pankreas fistülünü öngörmedeki rolü

Background: The albumin/globulin ratio (AGR) is one of several indicators of inflammation and immunity. This ratio has a prognostic significance in many malignant diseases. Previous studies have demonstrated a relationship between inflammatory mediators and post-operative pancreatic fistula (POPF). This study aimed to evaluate the relationship of AGR, a relatively new indicator, with post-operative pancreatic fistula (POPF).&#x0D; Methods: Pancreaticoduodenectomy (PD) patients between 2017 and 2020 were retrospectively analyzed and divided into two groups: (1) with and (2) without clinically relevant POPF (CR-POPF). The two groups were compared in terms of pre-operative–post-operative AGR and clinicodemographic characteristics. AGR was calculated as albumin/total protein–albumin, and the cutoff point for AGR was determined according to Youden’s index.&#x0D; Results: CR-POPF developed in 21% of 121 patients who underwent PD. No differences between the groups in terms of age, gender, comorbid disease status, pancreatic duct width, and anastomosis technique were found. Pre- and post-operative day-3 (POD3) albumin levels and AGR were found to be significantly lower in the CR-POPF group. Multivariate analysis showed that AGR and pancreatic tissue stiffness are independent risk factors for POPF development.&#x0D; Conclusion: Low AGR is an independent risk factor for the development of CR-POPF. To reduce the incidence of POPF, this ratio should be maintained at an optimal level. The use of AGR as a useful tool for predicting POPF in pancreaticoduodenectomy patients is suggested.

The association between albumin-globulin ratio (AGR) and survival in patients treated with immune checkpoint inhibitors.

The albumin-globulin ratio (AGR) could be a prognostic biomarker in patients with cancer, although the data is limited in patients treated with immune-checkpoint inhibitors (ICIs). We aimed to evaluate the association between AGR and survival in ICI-treated patients. The data of 212 advanced-stage patients were retrospectively evaluated in this cohort study. The association between AGR with overall (OS) and progression-free survival (PFS) were evaluated with multivariate analyses. Additionally, receptor operating curve (ROC) analysis was conducted to assess the AGR's predictive power in the very early progression (progression within two months) and long-term benefit (more than twelve months survival). The median AGR was calculated as 1.21, and patients were classified into AGR-low and high subgroups according to the median. In the multivariate analyses, patients with lower AGR (< 1.21) had decreased OS (HR: 1.530, 95% CI: 1.100-2.127, p= 0.011) and PFS (HR: 1.390, 95% CI: 1.020-1.895, p= 0.037). The area under curve of AGR to detect early progression and long-term benefit were 0.654 (95% CI: 0.562-0.747, p= 0.001) and 0.671 (95% CI: 0.598-0.744, p< 0.001), respectively. In our experience, survival with ICIs was impaired in patients with lower AGR. Additionally, the AGR values could detect the very early progression and long-term benefit ICIs.

Predictive factors for the development of lupus nephritis after diagnosis of systemic lupus erythematosus

ObjectivesTo determine predictive factors for the development of lupus nephritis (LN) at the time of diagnosis of systemic lupus erythematosus (SLE). MethodsA case-control study was carried out in a single center, 595 patients with a diagnosis of SLE without LN participated by clinical or laboratory parameters at diagnosis, they were followed for a mean of 6.8 (+4.5) years, conforming to the data of their files two groups: with NL (cases) and without NL (controls) at the end of the follow-up. Sociodemographic, clinical, serological, immunological variables and the albumin – globulin ratio (AGR), calculated as albumin/total protein-albumin at diagnosis, were compared between both groups. A univariate and multivariate analysis was carried out. Results124 (20.8%) patients had LN during follow-up and 471 (79.2%) did not develop LN. Univariate analysis: variables significantly associated with the development of LN: smoking, oral ulcers, serositis, more than four classification criteria, abrupt onset of SLE, higher SLEDAI value, low AGR, low C3 levels, high anti-titers. –Double stranded DNA (anti-dc DNA), anti-nucleosomes and positivity of immunofluorescence in skin. Multivariate analysis: predictors of developing LN: elevated serum levels of anti-dc DNA (odds ratio (OR): 15.82; confidence interval (CI): 1.08−1.22, P < .0001), decrease in the C3 fraction (OR: 36.50; CI: 13.52–81.91, P < .0001) and the RAG < 1 (OR: 47.58; CI: 11.85−79.17, P < .0001). ConclusionThe AGR below one was the greatest predictor of the appearance of LN, together with the low levels of C3 and high levels of anti-dc DNA antibodies, they may contribute to identifying patients with a higher risk of presenting LN.

Value of Preoperative Hematological Parameters in the Prognosis of Gastric Cancer Patients Undergoing a Total Gastrectomy.

This study aimed to evaluate the relationships between the albumin/globulin ratio (AGR), neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR) and clinicopathological information for gastric cancer patients. In addition, the prognostic values of these hematological parameters for resectable gastric cancer patients undergoing a total gastrectomy were determined. A total of 245 patients with gastric cancer who underwent a total gastrectomy at our hospital between January 1, 2005, and December 30, 2015, were enrolled into this study. The preoperative AGR, NLR, and PLR in the serum samples of the patients were measured. The relationships between the hematological parameters and the disease-free survival (DFS) as well as overall survival (OS) were analyzed by statistical analysis. The cutoff values of AGR, NLR, and PLR were 1.57, 3.5, and 193, respectively. Univariate analyses demonstrated that a low AGR, a high NLR, and a high PLR were significant risk factors for a poor prognosis. According to multivariate analysis, a high PLR was found to be independently associated with a poor survival. Additionally, when age was considered as a stratified factor, univariate analyses demonstrated that a low AGR had the tendency to be correlated with a shorter DFS in nonelderly patients (<65 years old). A low AGR was significantly correlated with a shorter DFS and OS in elderly patients (≥65 years old). AGR, NLR, and PLR are independent risk factors associated with a poor gastric cancer survival by univariate analysis, and AGR is an independent risk factor for predicting DFS and OS in elderly patients (≥65 years old) with gastric cancer after total gastrectomy.

Correlation between Preoperative Serum Albumin-Globulin Ratio and Prognosis of Patients Undergoing Low Rectal Cancer Surgery.

To explore the correlation between preoperative serum albumin-globulin ratio (AGR) and the prognosis of patients undergoing low rectal cancer surgery. A total of 152 patients treated from June 2013 to June 2015 were selected. They were divided into survival group (n = 128) and death group (n = 24). Their general clinical data and preoperative and postoperative serum albumin (ALB), globulin (GLB) levels, and AGR were compared. Multivariate logistic regression analysis was performed for influencing factors for postoperative death. A nomogram prediction model was established based on independent risk factors. The predictive value of AGR for clinical outcomes was analyzed by receiver operating characteristic (ROC) curve, and the optimal cut-off value was obtained. The correlation between AGR and postoperative clinical outcomes was analyzed. The patients were divided into group A and B according to cut-off value, survival curves were plotted by Kaplan-Meier method, and 5-year survival rates were compared. There were significant differences in tumor stage, cell differentiation, depth of tumor invasion, lymph node metastasis, chemotherapy, preoperative ALB, GLB, and AGR between the two groups, which were all independent risk factors for death. After operation, ALB and AGR significantly declined and were significantly lower in the death group than those in the survival group. The death group had significantly higher GLB level than that of the survival group. The optimal cut-off value of AGR for predicting death was 1.73. AGR was significantly correlated with postoperative clinical outcomes. The survival rate of patients with AGR > 1.73 significantly exceeded that of cases with AGR ≤ 1.73. The preoperative serum AGR is an independent risk factor for the postoperative clinical outcomes of patients with low rectal cancer and has a high predictive value. Lower AGR indicates higher risk of postoperative death.

Clinical Significance of Serum Albumin/Globulin Ratio in Patients With Pyogenic Liver Abscess.

Pyogenic liver abscess (PLA) remains a significant challenge for modern clinicians. Serum albumin/globulin ratio (AGR) can reflect the progress of many diseases. However, the clinical significance of AGR in PLA has not been evaluated. The aim of this study was to explore the effect of AGR on the clinical characteristic and prognosis in PLA patients. This retrospective study included 392 PLA patients who admitted to the First Affiliated Hospital of Xi'an Jiaotong University from January, 2007 to December, 2016. The medical records on admission were collected. Compared with the healthy controls and the patients with extraperitoneal infection or non-infectious liver disease, PLA patients had lower levels of AGR. The mean level of AGR in PLA patients was 1.02 ± 0.25. There were 179 (45.4%) patients with AGR > 1.02 and 213 (54.6%) patients with AGR ≤ 1.02. The baseline data and treatment plans of PLA patients with high or low AGR were comparative. However, PLA patients with a low AGR had higher body temperature, leukocytes and neutrophils, lower hemoglobin, poorer liver and coagulation function, larger abscess diameter, higher positive rate of pus culture and proportion of Escherichia coli, and were more susceptible to multiple bacteria. Moreover, PLA patients with a low AGR had more complications, including systemic inflammatory response syndrome (SIRS), peritoneal effusion and pleural effusion. And it also needs longer time for temperature normalization and hospital stay. In conclusion, PLA patients have lower AGR and lower AGR is associated with worse clinical manifestations, more complications and poorer prognosis. Thus, monitoring of AGR is of great clinical significance for evaluating the progress of PLA patients.

Evaluation and Validation of the Prognostic Value of Serum Albumin to Globulin Ratio in Patients With Cancer Cachexia: Results From a Large Multicenter Collaboration.

BackgroundRecently, albumin–globulin ratio (AGR), a serological indicator that reflects nutritional status and systemic inflammatory, has been reported to be associated with the prognosis of various cancers. However, there is currently no research report on its relationship with cancer cachexia.ObjectivesThis study aimed to explore the prognostic value of AGR in patients with cancer cachexia through a multicenter retrospective analysis.MethodsWe recruited 2,364 patients with cancer cachexia and randomly divided the patients into training and validation cohorts at a ratio of 7:3. The optimal stratification method was used to determine the optimal cutoff value of AGR. The survival curve was evaluated by the Kaplan–Meier method. Cox regression proportional-hazards model was used to determine independent prognostic factors in patients with cancer cachexia. The time-dependent receiver operating characteristic curve was used to compare the prognostic performance of different malnutrition evaluation tools.ResultsThe optimal cutoff value of AGR is 1.24 in patients with cancer cachexia. Increasing AGR was associated with survival in a dose–response manner with a forward L-shape. Compared with the high AGR group, the low AGR group had a shorter overall survival; and there was consistency in training and validation cohorts. In the stratified analysis of TNM stage, AGR has good prognostic distinguishing ability for advanced patients. Multivariate survival analysis determined that low AGR was an independent risk factor affecting all-cause mortality in patients with cancer cachexia. In addition, compared with other malnutrition evaluation tools, AGR could effectively stratify the prognosis of patients with cancer cachexia.ConclusionAGR was an independent prognostic factor affecting patients with cancer cachexia, especially in advanced patients. Compared with other malnutrition evaluation tools, AGR can effectively stratify the prognosis of patients with cancer cachexia.

Albumin-Globulin Ratio Is an Independent Determinant of 28-Day Mortality in Patients with Critical Illness.

Background Critical illness in the intensive care unit (ICU) has been a global health priority. Systemic nutritional status has turned out to be related to the prognosis of critically ill patients. The albumin-globulin ratio (AGR) has been reported to be a novel prognostic factor of many diseases. This study is aimed at investigating whether the AGR could predict the mortality risk in critically ill patients. Methods We enrolled 582 adult patients admitted to the respiratory intensive care unit (RICU). We collected the clinical and laboratory data. X-tile software was used to determine the optimal cut-off values for the AGR. Patients were divided into three groups according to the AGR (low AGR group with AGR < 0.8, medium AGR group with AGR ranging from 0.8 to 1.1, and high AGR group with AGR > 1.1). Kaplan-Meier analysis was used for survival analysis. A Cox proportional hazard model was applied to the univariate and multivariate analyses for the potential predictors associated with survival. Results Our present study showed that the AGR was related to the 28-day survival of critically ill patients in the RICU. The rate of pneumonia in the low AGR group was significantly higher than that in the other groups. Patients with a lower AGR present an increased risk of 28-day mortality compared to patients with a higher AGR. Cox regression analysis showed that the AGR might be an independent predictor of prognosis to 28-day survival in critically ill patients in the RICU. Medium and high AGR values remained independently associated with better 28-day survival than low AGR values (HR: 0.484 (0.263-0.892) (p = 0.02); HR: 0.332 (0.166-0.665) (p = 0.002)). Conclusion The AGR might be an independent predictor of prognosis in critically ill patients.

Usefulness of albumin-globulin ratio as a clinical prognostic factor in patients with thyroid cancer treated with radioiodine.

Albumin-globulin ratio (AGR), which is calculated by dividing serum albumin by serum globulin, is considered as a cancer-related inflammation biomarker. Although the prognosis of many solid cancers has been shown to be associated with AGR, there are no studies to demonstrate the association between the prognosis of thyroid cancer and AGR. The purpose of this study is to reveal the relationship between AGR and overall survival (OS) in patients with thyroid cancer who received radioactive iodine therapy (RIT). Eighty-eight patients with thyroid cancer who had received RIT for the first time in our institution were included. The values before RIT were adopted as initial measurements for serum albumin, globulin, and thyroglobulin (Tg) and used for analysis. Patients were divided into two groups based on the AGR value. We analyzed the relationship between clinical factors and treatment outcome. The median follow-up period was 92.4months (range: 30.1-173.9months). The 5-year OS and progression-free survival (PFS) were 94% and 54%, respectively. Seventeen patients (< 65years, 8; and ≥ 65years, 9) died during the follow-up period. Low AGR was significantly associated with OS in both univariate and multivariate analyses (p = 0.0059 and p = 0.0120, respectively). As the 5-year OS was as high as 94%, there was no significant difference in survival rate between the two groups during the first 5years. However, there seemed to be a remarkable difference in 10years after the first RIT. On the other hand, Tg was significantly associated with PFS in both univariate and multivariate analyses (p = 0.0016 and p = 0.0441, respectively). In patients under the age of 65, the PFS rate was significantly lower in the low AGR group (p < 0.0001), while there was no difference in PFS rate between the two AGR groups in patients aged 65years or older. AGR may be used as a prognostic factor in relatively younger patients with thyroid cancer treated with radioiodine, while it may be less useful in the older. Overall, it may be an independent prognostic factor for long-term survival in those with thyroid cancer.

The role of serum albumin/globulin ratio in combination with prognostic risk indexes of febrile neutropenia.

The aim of this study was to evaluate the effect of the serum albumin/globulin ratio (AGR) on the 30-day mortality of febrile neutropenia (FEN). The second aim of the study was to evaluate the effect of the combination of the AGR with the Multinational Association for Supportive Care in Cancer (MASCC) and Clinical Index of Stable Febrile Neutropenia (CISNE) risk indexes on 30-day mortality of FEN. A retrospective study evaluating the effect of serum AGR, MASCC and CISNE scores on 30-day FEN mortality. A total of 137 FEN episodes in 120 patients were included in this study. Nineteen patients (14%) died within the first 30days of FEN episodes. The 30-day mortality rate was calculated as 4% in patients with high AGR and 23% in patients with low AGR (P=.002). According to the MASCC and CISNE risk scores, the mortality rates in low-risk patients were 8% and 6%, respectively, and in the high-risk group 22% and 29%, respectively (P=.024 vs P<.001). In the group of patients with MASCC <21 and CISNE ≥3, the 30-day mortality rate was 7%, when the AGR was >1.13, and in those with AGR ≤1.13 mortality rate increased to 50% (P=.012). A low AGR in a patient with FEN was found to be associated with an increased risk of 30-day mortality. Combining the AGR with MASCC and CISNE risk indexes might increase the predictive value of these scoring systems on 30-day mortality.

Prognostic value of the albumin-globulin ratio and albumin-globulin score in patients with multiple myeloma.

ObjectiveThe albumin–globulin ratio (AGR) has been identified as a promising prognostic predictor of mortality in patients with hematological malignancies. This study investigated the prognostic significance of AGR in patients with multiple myeloma.MethodsTwo hundred patients diagnosed with multiple myeloma from January 2010 to October 2018 were retrospectively analyzed and followed up until December 2019. Kaplan–Meier curves and multivariate Cox regression analysis were applied to detect the prognostic value of AGR.ResultsThe median follow-up period was 36 months. The optimal cutoff of AGR was 1.16 according to receiver operating characteristic curve analysis. High AGR was significantly correlated with better overall survival (OS) and progression-free survival (PFS). Multivariate analysis revealed that low AGR was an independent prognostic factor for worse OS (hazard ratio [HR] = 1.82, 95% confidence interval [CI] = 1.15–2.94) and PFS (HR = 1.53, 95% CI = 1.09–2.17).ConclusionsAGR may represent a potential prognostic biomarker in patients with multiple myeloma.Mini : We demonstrated that high AGR was associated with a favorable overall survival and progression-free survival in patients with multiple myeloma.
