Red cell distribution width-to-albumin ratio is a simple promising prognostic marker in acute cholangitis requiring biliary drainage

Background: It is crucial to assess the severity of acute cholangitis(AC). There are currently several prognostic markers. However, the accuracies of these markers are not satisfied. The present study aimed to investigate the predictive value of the red cell distribution width(RDW)-to-albumin ratio(RAR) for the prognosis of AC. Methods: We retrospectively evaluated consecutive patients diagnosed with AC between May 2019 and March 2022. RAR was calculated, and its predictive ability for in-hospital mortality, intensive care unit(ICU) admission, bacteremia, and the length of hospitalization were analyzed. Results: Out of 438 patients, 34(7.8%) died. Multivariate analysis showed that malignant etiology [odds ratio(OR) = 4.816, 95% confidence interval(CI): 1.936-11.980], creatinine(OR = 1.649, 95% CI: 1.095-2.484), and RAR(OR = 2.064, 95% CI: 1.494-2.851) were independent risk factors for mortality. When adjusted for relevant covariates, including age, sex, malignant etiology, Tokyo severity grading(TSG), Charlson comorbidity index, and creatinine, RAR significantly predicted mortality(adjusted OR = 1.833, 95% CI: 1.280-2.624). When the cut-off of RAR was set to 3.8, its sensitivity and specificity for mortality were 94.1% and 56.7%, respectively. Patients with an RAR of > 3.8 had a 20.9-fold(OR = 20.9, 95% CI: 4.9-88.6) greater risk of mortality than the remaining patients. The area under the curve value of RAR for mortality was 0.835(95% CI: 0.770-0.901), which was significantly higher than that of TSG and the other prognostic markers, such as C-reactive protein-to-albumin ratio, and procalcitonin-to-albumin ratio. Lastly, RAR was not inferior to TSG in predicting ICU admission, bacteremia, and the length of hospitalization. Conclusions: RAR successfully predicted the in-hospital mortality, ICU admission, bacteremia, and the length of hospitalization of patients with AC, especially in-hospital mortality. RAR is a promising marker that is more convenient than TSG and other prognostic markers for predicting the prognosis of patients with AC.

Application of neutrophil-lymphocyte ratio and red blood cell distribution width in diabetes mellitus complicated with heart failure

BACKGROUND Accumulating clinical evidence has shown that diabetes mellitus(DM)is a serious risk factor for cardiovascular disorders and an important factor for adverse cardiovascular events.AIM To explore the value of the combined determination of the neutrophil-lymphocyte ratio(NLR)and red blood cell distribution width(RDW)in the early diagnosis and prognosis evaluation of DM complicated with heart failure(HF).METHODS We retrospectively analyzed clinical data on 65 patients with type 2 DM(T2DM)complicated with HF(research group,Res)and 60 concurrent patients with uncomplicated T2DM(control group,Con)diagnosed at Zhejiang Provincial People’s Hospital between January 2019 and December 2021.The NLR and RDW values were determined and comparatively analyzed,and their levels in T2DM+HF patients with different cardiac function grades were recorded.The receiver operating characteristic(ROC)curves were plotted to determine the NLR and RDW values(alone and in combination)for the early diagnosis of HF.The correlation between NLR and RDW with the presence or absence of cardiac events was also investigated.RESULTS Higher NLR and RDW levels were identified in the Res vs the Con groups(P<0.05).The NLR and RDW increased gradually and synchronously with the deterioration of cardiac function in the Res group,with marked differences in their levels among patients with grade II,III,and IV HF(P<0.05).ROC curve analysis revealed that NLR combined with RDW detection had an area under the curve of 0.915,a sensitivity of 76.9%,and a specificity of 100%for the early diagnosis of HF.Furthermore,HF patients with cardiac events showed higher NLR and RDW values compared with HF patients without cardiac events.CONCLUSION NLR and RDW were useful laboratory indicators for the early diagnosis of DM complicated with HF,and their joint detection was beneficial for improving diagnostic efficiency.Additionally,NLR and RDW values were directly proportional to patient outcomes.

Red cell distribution width/platelet ratio estimates the 3-year risk of decompensation in Metabolic Dysfunction-Associated Steatotic Liver Disease-induced cirrhosis

BACKGROUND For compensated advanced chronic liver disease(cACLD)patients,the first decompensation represents a dramatically worsening prognostic event.Based on the first decompensation event(DE),the transition to decompensated advanced chronic liver disease(dACLD)can occur through two modalities referred to as acute decompensation(AD)and non-AD(NAD),respectively.Clinically Significant Portal Hypertension(CSPH)is considered the strongest predictor of decompensation in these patients.However,due to its invasiveness and costs,CSPH is almost never evaluated in clinical practice.Therefore,recognizing noninvasively predicting tools still have more appeal across healthcare systems.The red cell distribution width to platelet ratio(RPR)has been reported to be an indicator of hepatic fibrosis in Metabolic Dysfunction-Associated Steatotic Liver Disease(MASLD).However,its predictive role for the decompensation has never been explored.AIM In this observational study,we investigated the clinical usage of RPR in predicting DEs in MASLD-related cACLD patients.METHODS Fourty controls and 150 MASLD-cACLD patients were consecutively enrolled and followed up(FUP)semiannually for 3 years.At baseline,biochemical,clinical,and Liver Stiffness Measurement(LSM),Child-Pugh(CP),Model for End-Stage Liver Disease(MELD),aspartate aminotransferase/platelet count ratio index(APRI),Fibrosis-4(FIB-4),Albumin-Bilirubin(ALBI),ALBI-FIB-4,and RPR were collected.During FUP,DEs(timing and modaities)were recorded.CSPH was assessed at the baseline and on DE occurrence according to the available Clinical Practice Guidelines.RESULTS Of 150 MASLD-related cACLD patients,43(28.6%)progressed to dACLD at a median time of 28.9 months(29 NAD and 14 AD).Baseline RPR values were significantly higher in cACLD in comparison to controls,as well as MELD,CP,APRI,FIB-4,ALBI,ALBI-FIB-4,and LSM in dACLD-progressing compared to cACLD individuals[all P<0.0001,except for FIB-4(P:0.007)and ALBI(P:0.011)].Receiving operator curve analysis revealed RPR>0.472 and>0.894 as the best cut-offs in the prediction respectively of 3-year first DE,as well as its superiority compared to the other non-invasive tools examined.RPR(P:0.02)and the presence of baseline-CSPH(P:0.04)were significantly and independently associated with the DE.Patients presenting baseline-CSPH and RPR>0.472 showed higher risk of decompensation(P:0.0023).CONCLUSION Altogether these findings suggest the RPR as a valid and potentially applicable non-invasive tool in the prediction of timing and modalities of decompensation in MASLD-related cACLD patients.

Red blood cell distribution width derivatives in alcohol-related liver cirrhosis and metabolic-associated fatty liver disease

BACKGROUND Looking for undiscovered blood markers of liver fibrosis and steatosis still remains an issue worth exploring.There are still plenty of unresolved issues related to the actual role of hematological indices as potential markers of liver function.AIM To study red blood cell distribution width(RDW),RDW-to-platelet ratio(RPR)and RDW-to-lymphocyte ratio(RLR) in alcohol-related liver cirrhosis(ALC) and metabolic-associated fatty liver disease(MAFLD).METHODS The study group was composed of 302 people:142 patients with ALC and 92 with MAFLD;68 persons were included as controls.RDW,RPR and RLR were measured in each person.Indirect and direct parameters of liver fibrosis were also assessed [aspartate transaminase to alkaline transaminase ratio,aspartate transaminase to platelet ratio index(APRI),fibrosis-4(FIB-4),gamma-glutamyl transpeptidase to platelet ratio(GPR),procollagen I carboxyterminal propeptide,procollagen Ⅲ aminoterminal propeptide,transforming growth factor-α,plateletderived growth factor AB,laminin].MELD score in ALC patients and nonalcoholic fatty liver disease(NAFLD) fibrosis score together with BARD score were obtained in the MAFLD group.The achieved results were compared to controls.Then a correlation between assessed markers was done.Diagnostic value of each investigated parameter and its suggested cut-off in the research group RESULTS RDW,RPR and RLR values turned out to be significantly higher in ALC and MAFLD groups compared to controls(ALC:P<0.0001;NAFLD:P<0.05,P<0.0001 and P<0.0001,respectively).RPR correlated positively with MELD score(P<0.01) and indirect indices of liver fibrosis(FIB-4 and GPR;P<0.0001) in ALC patients;negative correlations were found between PDGF-AB and both:RDW and RPR(P<0.01 and P<0.0001,respectively).RPR correlated positively with NAFLD fibrosis score and APRI(P<0.0001) in the MAFLD group;a positive relationship was observed between RDW and FIB-4,too(P<0.05).AUC values and suggested cut-offs for RDW,RPR and RLR in ALC patients were:0.912(>14.2%),0.965(>0.075) and 0.914(>8.684),respectively.AUC values and suggested cut-offs for RDW,RPR and RLR in MAFLD patients were:0.606(>12.8%),0.724(>0.047) and 0.691(>6.25),respectively.CONCLUSION RDW with its derivatives appear to be valuable diagnostic markers in patients with ALC.They can also be associated with a deterioration of liver function in this group.

Red cell distribution width/albumin ratio and 90-day mortality after burn surgery

Background:Red cell distribution width(RDW)and serum albumin concentration are associated with postoperative outcomes.However,the usefulness of the RDW/albumin ratio in burn surgery remains unclear.Therefore,we evaluated the association between RDW/albumin ratio and 90-day mortality after burn surgery.Methods:Between 2013 and 2020,a retrospective review of patients in a burn intensive care unit(ICU)was performed.Receiver operating characteristic curve,multivariate Cox logistic regression,multivariate logistic regression and Kaplan-Meier analyses were conducted to evaluate the associ-ation between RDW/albumin ratio and 90-day mortality after burn surgery.Additionally,prolonged ICU stay rate(>60 days)and ICU stay were assessed.Results:Ninety-day mortality was 22.5%(210/934)in burn patients.Risk factors for 90-day mortality were RDW/albumin ratio at postoperative day 1,age,American Society of Anesthesiologists physical status,diabetes mellitus,inhalation injury,total body surface area burned,hypotensive event and red blood cell transfusion volume.The area under the curve of the RDW/albumin ratio at postoperative day 1 to predict 90-day mortality,after adjusting for age and total body surface area burned,was 0.875(cut-off value,6.8).The 90-day mortality was significantly higher in patients with RDW/albumin ratio>6.8 than in those with RDW/albumin ratio≤6.8(49.2%vs 12.3%,p<0.001).Prolonged ICU stay rate and ICU stay were significantly higher and longer in patients with RDW/albumin ratio>6.8 than in those with RDW/albumin ratio≤6.8(34.5%vs 26.5%;21[11-38]vs 18[7-32]days).Conclusion:RDW/albumin ratio>6.8 on postoperative day 1 was associated with higher 90-day mortality,higher prolonged ICU stay rate and longer ICU stay after burn surgery.
