Abstract
Lower extremity arterial disease (LEAD) is caused by atherosclerotic plaque in the arterial supply to the lower limbs. The neutrophil to lymphocyte and platelet to lymphocyte ratios (NLR, PLR) are established markers of systemic inflammation which are related to inferior outcomes in multiple clinical conditions, though remain poorly described in patients with LEAD. This review was carried out in accordance with PRISMA guidelines. The MEDLINE database was interrogated for relevant studies. Primary outcome was the prognostic effect of NLR and PLR on clinical outcomes following treatment, and secondary outcomes were the prognostic effect of NLR and PLR on disease severity and technical success following revascularisation. There were 34 studies included in the final review reporting outcomes on a total of 19870 patients. NLR was investigated in 21 studies, PLR was investigated in two studies, and both NLR & PLR were investigated in 11 studies. Relating to increased levels of systemic inflammation, 20 studies (100%) reported inferior clinical outcomes, 13 (92.9%) studies reported increased disease severity, and seven (87.5%) studies reported inferior technical results from revascularisation. The studies included in this review support the role of elevated NLR and PLR as key components influencing the clinical outcomes, severity, and success of treatment in patients with LEAD. The use of these easily accessible, cost effective and routinely available markers is supported by the present review.

Abstract
OBJECTIVES We examined the effect of sarcopenia on early surgical outcomes in patients with critical limb ischemia (CLI) in terms of major adverse cardiac events (MACE) and major adverse limb events (MALE), as well as the value of inflammatory markers of neutrophil-to-lymphocyte (NLR) and platelet-to-lymphocyte ratios (PLR) as indicators of sarcopenia in CLI patients. METHODS This was an observational retrospective single-center study. Patients who required surgical revascularization for CLI between October 2015 and December 2020 were identified. Psoas muscle areas were calculated from computed tomography images for psoas muscle index (PMI) calculations. Sarcopenia was defined as PMI < 5.5 cm2/m2 for men and PMI < 4.0 cm2/m2 for women. Risk factors for 30-day major adverse cardiac events (MACE) and major adverse limb events (MALE) were analyzed. NLR and PLR were compared between sarcopenic and non-sarcopenic patients. RESULTS The mean age of 217 study patients was 61.5 ± 10.9, and 16 (7.4%) patients were female. 82 (37.8%) patients were sarcopenic. Patients with sarcopenia were older (65.1 ± 9.3 vs 59.4 ± 11.2, p < .001) and history of myocardial infarction was more frequent (23.2% vs 12.6%, p = 0.042) among sarcopenic patients. Sarcopenic patients more frequently encountered MACE (9.8% vs 0.7%, p = 0.002), but not MALE. Sarcopenia increased early postoperative MACE in our cohort with an odds ratio of 11.925. NLR was not different between the two groups, while PLR was higher (127.16 vs 104.06, p = 0.010) among sarcopenic patients. The platelet-to-lymphocyte ratio of 125.11 had a sensitivity of 53.7% and a specificity of 68.1% for differentiating sarcopenia. CONCLUSIONS Sarcopenia was associated with more frequent 30-day MACE and perioperative mortality after revascularization for CLI. 30-day MALE was not increased in patients with sarcopenia. The use of PLR as a simple marker of sarcopenia is limited by its low sensitivity and specificity.

The Impact of Clinical Follow-Up After Revascularization on the Outcomes of Patients with Chronic Limb Threatening Ischemia. Ann Vasc Surg 2022; 86:286-294. [PMID: 35803459 DOI: 10.1016/j.avsg.2022.05.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 05/04/2022] [Accepted: 05/28/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND Guidelines for optimal follow-up for patients undergoing lower extremity revascularization (LER) for peripheral arterial disease recommend multiple visits with imaging during the first year followed by yearly monitoring thereafter. Critical limb-threatening ischemia (CLTI) patients are at a greater risk for mortality and limb amputation than claudicants and thus necessitate closer monitoring. The goal of this article is to study the effects of compliance with follow-up after revascularization for patients with CLTI on major amputation rates and mortality. METHODS A single-center retrospective chart review of consecutive patients undergoing LER for CLTI was performed. Patients were stratified based on compliance with follow-up to compliant or noncompliant cohorts. Patient characteristics, reinterventions, and perioperative and long-term outcomes were compared between the 2 groups. RESULTS There were 356 patients undergoing LER and 61% (N = 218) were compliant. There was no significant difference in baseline characteristics between the 2 groups. Noncompliant patients were more likely to undergo endovascular interventions compared to compliant patients (92.8% vs. 79.4%, P = 0.03). There was no difference in perioperative outcomes between the 2 groups with overall 30-day mortality of 0.6%. After mean follow-up of 2.7 years, compliant patients had greater ipsilateral reintervention rates (49.1% vs. 34.1%, P = 0.005) and overall reintervention rates (61% vs. 44.2%, P = 0.002) compared to noncompliant patients. There was no significant difference in mortality or ipsilateral major amputations between the 2 groups. CONCLUSIONS Patients who were compliant with follow-up after LER for CLTI underwent more reinterventions with no difference in mortality or major limb amputation. Further research regarding the threshold for reintervention and the optimal schedule for follow-up in patients with CLTI is needed.

JOURNAL DE MEDECINE VASCULAIRE 2022; 47:116-124. [PMID: 36055680 DOI: 10.1016/j.jdmv.2022.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Accepted: 07/17/2022] [Indexed: 06/15/2023]
Abstract
OBJECTIVE Demonstrate that simplified ERICVA (Valladolid Critical Limb Ischaemia Risk Scale) is useful in predicting amputation in chronic limb-threatening ischemia (CLI) after one year of revascularization. METHODS A retrospective cohort study was performed. We analyzed the medical records of 93 patients over the age of 35 with the diagnosis of CLI who were treated in the Department of Internal Medicine, Orthopedics or in the Cardiovascular Surgery Unit of the Víctor Lazarte Echegaray Hospital and the High Complexity Virgen de La Puerta Hospital during the period 2015-2018. The simplified ERICVA score was determined in patients before surgical and endovascular revascularization. We included 31 patients who scored 2 or more points in the exposed group and 62 patients who scored less than 2 points in the group not exposed to amputation risk. The collected data was analyzed with the statistical program SPSS where the Relative Risk and significance was obtained with Pearson's Chi-square. The multivariate analysis was also carried out in order to obtain the adjusted relative risk. RESULTS It was identified that the simplified ERICVA score greater than or equal to 2 points was more frequent in those who underwent amputation (90.3%) compared to patients who did not undergo amputation (4.8%), increasing the risk of amputation in those patients with CLI who underwent revascularization (RR: 18.67, P<0.001). It was also possible to identify that within the group of patients that showed a high risk of amputation according to the ERICVA scale, they had a higher risk of major amputation (RR: 9.32, P<0.001) as opposed to the risk of minor amputation (RR: 1, 89, P=0.193). Among the items of the simplified ERICVA scale, the preoperative neutrophil-lymphocyte ratio and hematocrit were significantly higher in the group of amputated patients (P<0.001). In addition, it was possible to identify that the score greater than or equal to 2 was independently associated with the risk of amputation in patients revascularized with CLI (RR: 13.5, P<0.001). CONCLUSION In our patient population, the simplified ERICVA scale is useful in predicting major and minor amputation in critical limb ischemia after revascularization. The present data showed that the patients who had a simplified ERICVA score greater than or equal to 2 had a higher risk of major amputation compared to the risk of minor amputation. However, it is important to highlight that the impact on the prediction of minor amputation is greater because in some circumstances major amputation can appear as a complication of CLI.

Abstract
Background Two-year longevity is a crucial consideration in revascularization strategies for patients with symptomatic lower extremity arterial disease (LEAD). However, factors associated with 2-year longevity and risk stratification in octogenarians or nonagenarians have been underreported. Objective This paper aims to investigate the associated variables and stratify the 2-year prognosis in older patients with LEAD. Methods We performed logistic regression and association rule mining based on the Apriori algorithm to discover independent variables and validate their associations with 2-year longevity. Malnutrition, inflammation, and stroke factors were identified. C statistics and Kaplan-Meier analysis were used to assess the impact of different numbers of malnutrition, inflammation, and stroke factors on 2-year longevity. Results We recruited a total of 232 octogenarians or nonagenarians (mean age 85 years, SD 4.2 years) treated with endovascular therapy. During the study period, 81 patients died, and 27 of those (33%) died from a cardiac origin within 2 years. Association rules analysis showed the interrelationships between 2-year longevity and the neutrophil-lymphocyte ratio (NLR) and nutritional status as determined by the Controlling Nutritional Status (CONUT) score or Geriatric Nutritional Risk Index (GNRI). The cut-off values of NLR, GNRI, and CONUT were ≥3.89, ≤90.3, and >3, respectively. The C statistics for the predictive power for 2-year longevity were similar between the CONUT score and the GNRI-based models (0.773 vs 0.760; P=.57). The Kaplan-Meier analysis showed that 2-year longevity was worse as the number of malnutrition, inflammation, and stroke factors increased from 0 to 3 in both the GNRI-based model (92% vs 68% vs 46% vs 12%, respectively; P<.001) and the CONUT score model (87% vs 75% vs 49% vs 10%, respectively; P<.001). The hazard ratio between those with 3 factors and those without was 18.2 (95% CI 7.0-47.2; P<.001) in the GNRI and 13.6 (95% CI 5.9-31.5; P<.001) in the CONUT score model. Conclusions This study demonstrated the association and crucial role of malnutrition, inflammation, and stroke factors in assessing 2-year longevity in older patients with LEAD. Using this simple risk score might assist clinicians in selecting the appropriate treatment.

Abstract
Lower limb amputations due to ischemia represent an important health care and social issue. However, there are currently no specific biomarkers able to predict the risk of amputation and postamputation complications and prognosis. We conducted a systematic review of studies investigating whether blood cell count indexes of systemic inflammation are linked to the risk and the outcome of lower limb amputations due to ischemia. Overall, in 22 studies involving 8832 patients selected for review, several blood cell count indexes, particularly the neutrophil lymphocyte ratio, showed some promise in terms of predicting amputations and general outcomes of conservative and surgical treatments, as well as postamputation complications and prognosis. However, largely due to methodological limitations, further prospective studies are required to establish the clinical utility and applicability of blood cell indexes in the routine management of patients with ischemia-related lower limb amputations.

Ann Vasc Surg 2020; 72:72-78. [PMID: 32479878 DOI: 10.1016/j.avsg.2020.05.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 05/16/2020] [Accepted: 05/21/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND Sarcopenia is a factor of poor prognosis for patients with critical limb threatening ischemia (CLTI), but its diagnosis requires imaging measurements and is time consuming. We investigated whether preoperative platelet-to-lymphocyte ratio (PLR) could be an easy and rapid marker of sarcopenia. METHODS Patients treated for CLTI between January 2019 and July 2019 were included in this single-center retrospective study. Sarcopenia was defined by a psoas muscle index (PMI) <5.5 cm2/m2 in men, and <4.0 cm2/m2 in women. PLR was calculated for all patients based on their systematic preoperative blood analysis. The diagnostic power of PLR was analyzed through a receiver operating characteristic (ROC) curve. Early outcomes of sarcopenic patients in terms of 30-day mortality and 30-day morbidity were retrieved. RESULTS Sixty-four patients were included in the study: 48 nonsarcopenic patients (mean PMI 7.34 cm2/m2; interquartile range [IQR] 6.58-8.01) and 16 sarcopenic patients (mean PMI 4.30 cm2/m2; IQR 3.45-5.17). No difference was found between both groups regarding patient demographics, clinical characteristics, cardiovascular risk factors, comorbidities, or revascularization modalities. PLR was significantly higher in the sarcopenic group (mean 332.1; IQR 158.2-320.7) compared with the nonsarcopenic group (mean 204.6; IQR 133.8-265.6) (P = 0.02). A PLR value ≥292.5 was shown to be a diagnostic marker for sarcopenia based on the ROC curve (sensitivity 31.3%, specificity 91.7%). Thirty-day mortality was 12.5% in the sarcopenic group and 2.1% in the nonsarcopenic group (P = 0.15); 30-day morbidity was 56.3% in the sarcopenic group and 10.4% in the nonsarcopenic group (P < 0.001). CONCLUSIONS PLR might help identifying a subgroup of CTLI patients associated with poor prognosis but does not seem appropriate to be used as a marker of sarcopenia given its low sensitivity.
