RESUMEN
BACKGROUND: Research on the combined use of ear acupoint embedding beans and warming meridians with cold-dispersing formulas for alleviating resting pain in patients with arteriosclerosis obliterans (ASO) remains limited. AIM: To explore the therapeutic efficacy of auricular point embedding beans combined with Wenjing Sanhan prescription in alleviating resting pain in patients with lower-limb ASO. METHODS: A total of 100 patients with ASO experiencing resting pain who were treated at our hospital from January 2022 to January 2023 were enrolled. They were randomly allocated into two groups using a double-blind approach. The control group was treated using a warming meridian with a cold-dispersing formula, while the study group received additional treatment with ear acupoint embedding beans. The clinical efficacy, ankle-brachial artery pressure ratio, hemorheological indicators, and traditional Chinese medicine symptom scores were compared between the two groups. RESULTS: The clinical efficacy rate in the study group was significantly higher (94.00%) than that in the control group (72.00%, P < 0.05). Moreover, the ankle-brachial artery pressure ratio was significantly higher in the study group after treatment (P < 0.05). Hemorheological parameters, including whole blood viscosity, plasma viscosity (1.83 ± 0.11) mPa/s, fibrinogen levels (3.30 ± 0.21) g/L, platelet adhesion rate (49.87% ± 10.51%), and erythrocyte aggregation index (1.79 ± 0) were improved in the study group compared to the control group. In addition, the scores for decreased skin temperature (1.41 ± 0.26), intermittent claudication (1.30 ± 0.20), and resting pain (1.23 ± 0.31) were significantly lower in the study group than those in the control group (all P < 0.05). The level of oxidative stress in the study group also exhibited significant improvement (P < 0.05), and the levels of inflammatory factors were considerably lower than those in the control group. CONCLUSION: The combination of ear point embedding beans and Wenjing Sanhan prescription demonstrates promising clinical efficacy in alleviating resting pain associated with ASO.
RESUMEN
Objectives: The prevalence of peripheral arterial disease (PAD) is on the rise, with endovascular treatment being a widely accepted surgical intervention. Patients with PAD often experience reduced activities of daily living (ADL). Therefore, we conducted a retrospective cohort study to investigate the impact of early rehabilitation after endovascular treatment in patients with PAD. Methods: Using data from the JMDC hospital database, the study included 529 patients who were hospitalized for PAD and underwent endovascular treatment. Patients were classified into two independent variables: early rehabilitation group (rehabilitation started within 2 days postoperatively) and control group (rehabilitation started within 3-7 days postoperatively). The outcome measures were the occurrence of hospital-associated disability (HAD) and duration of hospitalization. Results: Unadjusted data showed that the early rehabilitation group (n=469) had fewer HAD events (8.5% vs. 23.3%, P <0.001) and a shorter mean hospitalization duration (4.4 vs. 18.9 days, P <0.001) than the control group (n=60). The difference remained significant after adjustment by propensity score analysis. Conclusions: In patients with PAD, early rehabilitation after endovascular treatment may be beneficial in preventing the development of HAD and reducing the duration of hospitalization.
RESUMEN
BACKGROUND: Excessive vascular smooth muscle cell (VSMC) proliferation and migration are the main contributors to the symptoms of lower-extremity arteriosclerosis obliterans (ASO). Previous studies suggested that microRNAs (miRNAs) regulate VSMC activity. Nevertheless, the molecular mechanisms by which they do so are unclear. OBJECTIVE: The present study aimed to identify the biological processes accounting for the effects of miR-140-3p on VSMCs in ASO. METHODS: The expression levels of miR-140-3p in clinical samples were analyzed by real-time polymerase chain reaction. An ASO cell model was established to investigate the expression of miR-140-3p on VSMCs. The transwell® assays and MTT assays were used to assess migration and proliferation. The interaction between RhoA and miR-140-3p was verified using the Dualluciferase reporter assay. Western blot technique was used to identify RhoA, RhoA-associated protein kinase 1 (ROCK1), and ROCK2. RESULTS: We discovered that miR-140-3p inhibited the proliferation, migration, and invasion but promoted the apoptosis of VSMCs, and RhoA was its downstream target gene. RhoA, ROCK1, and ROCK2 were upregulated in vascular tissues damaged by ASO compared to normal, healthy arteries. MiR-140-3p also decreased RhoA, ROCK1, and ROCK2 mRNA and protein expression. CONCLUSION: Overall, the present work partially elucidated the mechanism by which miR-140-3p regulates VSMC function and offered novel insights into potential therapeutic approaches for patients with lower-extremity arteriosclerosis obliterans.
RESUMEN
BACKGROUND: Arteriosclerosis obliterans (ASO) is a chronic arterial disease that can lead to critical limb ischemia. Endovascular therapy is increasingly used for limb salvage in ASO patients, but the outcomes vary. The development of prediction models using unsupervised machine learning may lead to the identification of novel subtypes to guide patient prognosis and treatment. METHODS: This retrospective study analyzed clinical data from 448 patients with ASOs who underwent endovascular therapy. Unsupervised machine learning algorithms were employed to identify subgroups. To validate the precision of the clustering outcomes, an analysis of the postoperative results of the clusters was conducted. A prediction model was constructed using binary logistic regression. RESULTS: Two distinct subgroups were identified by unsupervised machine learning and characterized by differing patterns of clinical features. Patients in Cluster 2 had significantly worse conditions and prognoses than those in Cluster 1. For the novel ASO subtypes, a nomogram was developed using six predictive factors, namely, platelet count, ankle brachial index, Rutherford category, operation method, hypertension, and diabetes status. The nomogram achieved excellent discrimination for predicting membership in the two identified clusters, with an area under the curve of 0.96 and 0.95 in training cohort and internal test cohort. CONCLUSION: This study demonstrated that unsupervised machine learning can reveal novel phenotypic subgroups of patients with varying prognostic risk who underwent endovascular therapy. The prediction model developed could support clinical decision-making and risk counseling for this complex patient population. Further external validation is warranted to assess the generalizability of the findings.

This study aims to elucidate the effect of alprostadil (ALP) plus cilostazol (CIL) on the treatment outcomes and inflammatory factors in patients with lower extremity arteriosclerosis obliterans (LEASO) receiving evidence-based care. Firstly, 130 patients with LEASO were selected from February 2020 to February 2023 and then randomly divided into two groups with 65 patients each. Excluding the dropouts, 59 patients in the control group (6 cases of dropout) received ALP and 62 patients in the research group (3 cases of dropout) received ALP plus CIL. Both groups were cared for in accordance with the evidence-based care model. Treatment outcomes, arteriosclerosis indexes (blood flow of dorsalis pedis artery [DPA], ankle-brachial index [ABI] and toe-brachial index [TBI]), hemorheological parameters (erythrocyte aggregation index [EAI], erythrocyte deformation index [EDI], high blood viscosity [HBV] and haematocrit [HCT]), inflammatory factors (interleukin [IL]-6, IL-8 and tumour necrosis factor [TNF]-α) and complications (nausea, diarrhoea, headache and transaminase elevation) were compared between the control and research groups. Results show that the overall response rate was markedly higher in the research group (90.32%) than in the control group (74.58%). Additionally, the blood flow of DPA, ABI and TBI in the research group significantly increased after the treatment and were higher than those in the control group. Meanwhile, the EAI, EDI, HBV, HCT, IL-6, IL-8 and TNF-α were significantly lower. The two groups did not differ markedly in the complication rate. The above findings suggest that ALP plus CIL is effective for patients with LEASO receiving evidence-based care. It can significantly improve arteriosclerosis indexes and hemorheological parameters while inhibiting serum inflammatory responses, with some certain safety.

This study aimed to decipher the mechanism of circular ribonucleic acids (circRNAs) in lower extremity arteriosclerosis obliterans (LEASO). First, bioinformatics analysis was performed for screening significantly down-regulated cardiac specific circRNA-circHAT1 in LEASO. The expression of circHAT1 in LEASO clinical samples was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The protein expression of splicing factor arginine/serine-rich 1 (SFRS1), α-smooth muscle actin (α-SMA), Calponin (CNN1), cyclin D1 (CNND1) and smooth muscle myosin heavy chain 11 (SMHC) in vascular smooth muscle cells (VSMCs) was detected by Western blotting. Cell Counting Kit-8 (CCK-8), 5-ethynyl-2'-deoxyuridine (EdU) and Transwell assays were used to evaluate cell proliferation and migration, respectively. RNA immunoprecipitation (RNA-IP) and RNA pulldown verified the interaction between SFRS1 and circHAT1. By reanalyzing the dataset GSE77278, circHAT1 related to VSMC phenotype conversion was screened, and circHAT1 was found to be significantly reduced in peripheral blood mononuclear cells (PBMCs) of LEASO patients compared with healthy controls. Knockdown of circHAT1 significantly promoted the proliferation and migration of VSMC cells and decreased the expression levels of contractile markers. However, overexpression of circHAT1 induced the opposite cell phenotype and promoted the transformation of VSMCs from synthetic to contractile. Besides, overexpression of circHAT1 inhibited platelet-derived growth factor-BB (PDGF-BB)-induced phenotype switch of VSMC cells. Mechanistically, SFRS1 is a direct target of circHAT1 to mediate phenotype switch, proliferation and migration of VSMCs. Overall, circHAT1 regulates SFRS1 to inhibit the cell proliferation, migration and phenotype switch of VSMCs, suggesting that it may be a potential therapeutic target for LEASO.
RESUMEN
OBJECTIVE: Oxidative damage is observed in the ischemic limbs of patients with arteriosclerosis obliterans. We investigated whether pemafibrate, a selective peroxisome proliferator-activated receptor alpha modulator, reduced oxidative stress in ischemic limbs and consequently rescued limb damage in model mice. MATERIALS AND METHODS: We surgically induced hind-limb ischemia in mice and orally administered pemafibrate solution (P-05 group, 0.5 mg/kg/day; P-10 group, 1.0 mg/kg/day) or control solution (control group). Seven days after the surgery, differences in reactive oxygen species (ROS) contents, antioxidative enzyme and transcription factor expression, blood flow, and capillary density in ischemic limbs were assessed. RESULTS: Tissue ROS levels were lower in the P-05 and P-10 groups compared with those in the control group. Although the tissue expression levels of nuclear factor-erythroid 2-related factor 2 increased in the P-10 group compared with that in the control group, no corresponding changes were observed in the tissue expression of four antioxidative enzymes. The limb salvage rates and capillary densities in ischemic limbs were higher in the P-05 and P-10 groups than that in the control group. CONCLUSION: Pemafibrate treatment reduced oxidative stress and augmented angiogenesis in ischemic limbs, contributing to prevention of limb damage in mice.

BACKGROUND: Lower extremity arteriosclerosis obliterans (ASO) is the most common occlusive disease of the peripheral blood vessels. OBJECTIVE: To explore the application effect of symptom management-based rehabilitation strategy in postoperative functional exercises in patients with lower extremity ASO. METHODS: The researchers selected 136 patients that underwent lower extremity ASO surgery for the first time in their department from January to September 2020. Patients were divided into a control group (n= 68) and an experimental group (n= 68). The control group implemented routine discharge rehabilitation education and continuous nursing. On this basis, the experimental group applied the symptom management theory to the rehabilitation management strategy to compare the degree of pain, the ankle-brachial index, self-care ability and quality of life between the two groups before and after the intervention. RESULTS: Three months (P= 0.045) and six months (P=0.013) after discharge, the experimental group's degree of pain was significantly lower than that of the control group. At one month (P= 0.019), three months (P= 0.003) and six months (P= 0.000) after discharge, the experimental group recovered significantly better than the control group. At six months after discharge, the self-care ability, mood status and physical pain of the experimental group were significantly higher than in the control group (P< 0.05). CONCLUSION: The rehabilitation management strategy, which is based on symptom management theory, can effectively improve the symptoms, quality of life and self-efficacy of ASO patients in continuous care. This nursing strategy is worthy of clinical promotion.

RESUMEN
Objective:To investigate the efficacy of excimer laser atherectomy (ELA) combined with drug-coated balloon (DCB) in the treatment of femoropopliteal arteriosclerosis obliterans (ASO) and its influencing factors.Methods:The clinical data of patients with femoropopliteal ASO treated by ELA combined with DCB from July 2019 to March 2022 were retrospectively analyzed, including technical success rate, ankle-brachial index(ABI), primary patency rate and freedom from target lesion revascularization (TLR) rate. Cox regression was applied to analyze the risk factors affecting the decline in the rate of primary patency and freedom from TLR.Results:All 82 patients were treated with ELA+DCB. The technical success was 91.5%. The post-operative ABI (0.73±0.13) was significantly higher than preoperative ABI (0.39±0.11) ( t=35.26, P<0.001). The 24-month cumulative primary patency and TLR-free rates were 64.1% and 76.8%, respectively. Lesion length>15 cm ( HR=2.57, P=0.047) and severe calcification ( HR=3.26, P=0.021) were associated with loss of primary patency. Having diabetes ( HR=5.24, P=0.010) and a single postoperative outflow tract ( HR=4.18, P=0.008) were associated with a decrease in TLR-free rates. Conclusions:ELA combined with DCB for femoropopliteal ASO is safe and has good intermediate efficacy. Lesion length>15 cm and severe calcification were independent risk factors for primary patency rate, and diabetes and a single postoperative outflow tract were independent risk factors for TLR-free rate.
RESUMEN
Objective To explore the effect of different treatment methods on prognosis in elderly patients with lower extremity arterial occlusive disease.Methods A total of 352 elderly patients with lower extremity arterial occlusive disease admitted in our hospital from May 2020 to May 2022 were enrolled,and according to their willingness and characteristics of lower extremity le-sions,they were divided into balloon dilation group(142 patients),stent implantation group(145 patients)and conservative treatment group(65 patients).All patients were followed up for 13-24 months.The incidences of major adverse cardiovascular events(MACE),including all-cause death,acute myocardial infarction,acute ischemic stroke,and major adverse lower limb events(MALE),including lower extremity pain at rest,ulcers or skin defects,gangrene,reocclusion,and amputation were observed and recorded.The clinical data and prognosis were compared and ana-lyzed of the three groups.Kaplan-Meier survival curves were drawn.Results The incidence of all-cause mortality was significantly lower in the stent implantation group than the conservative treatment group(9.7%vs 23.1%,P<0.01).The incidence of MALE was obviously lower in the stent implantation group and the balloon dilatation group than the conservative treatment group(4.8%and 9.2%vs 24.6%,P<0.01).Conclusion Endovascular therapy can reduce the risk of all-cause death and MALE occurrence in elderly patients with lower extremity arterial occlusive disease who are suitable for interventional therapy.
RESUMEN
Objective:To construct a predictive model for the risk of major adverse cardiovascular events(MACE) after surgery in patients with symptomatic arteriosclerosis obliterans(ASO) .Methods:From Jan 2018 to Dec 2021, 957 patients with symptomatic ASO admitted to Nanjing Drum Tower Hospital were selected and divided into MACE and non-MACE groups according to whether they had a post-op MACE. A risk prediction model was constructed based on a stepwise regression method with multi-factor COX regression analysis. The model was evaluated using the receiver operating characteristic curve (ROC), the calibration curve to assess the model fit, and the Bootstrap method for internal validation.Results:MACE occurred in 143 patients (14.94%). After COX regression analysis, BMI, creatinine clearance, fibrinogen, rivaroxaban and previous history of surgery were enrolled into model constructing. The ROC curve assessed the model with a C-statistic of 0.690 (95% CI: 0.644-0.736), sensitivity and specificity of 49.2% and 80.7% respectively, a Jorden index of 0.299 and an optimal cut-off value of 0.086. Calibration curves showing agreement between predicted and actual observed values. Internally validated C-statistic of 0.689 (95% CI: 0.672-0.700). The population was divided into high and low risk groups based on the best cut-off value and analysed for survival. The difference between the two groups was statistically different. Conclusion:The risk prediction model for the occurrence of MACE based on clinical parameters is simple and convenient, with good predictability and good discriminatory ability, and can provide reference for the assessment and treatment of MACE in ASO patients.
RESUMEN
BACKGROUND: Endoluminal interventions have become one of the main options for the treatment of arteriosclerosis obliterans (ASO). OBJECTIVE: To explore the effect of hydration therapy and nursing intervention on the prevention of contrast-induced nephropathy (CIN) after interventional treatment of lower extremity ASO. METHODS: A convenience sampling method was used to select 94 patients who received ASO treatment in our hospital from March 2019 to May 2021 as the study subjects. All patients underwent endovascular interventional therapy and were randomly divided into two groups by the random number table method, with odd numbers entering the observation group (n= 47) and even numbers entering the control group (n= 47). The control group received routine nursing intervention, while the observation group underwent hydration therapy and had a corresponding nursing intervention scheme. The clinical efficacy of the two groups and the incidence of contrast-induced nephropathy after interventional therapy were compared, and an evaluation of satisfaction within the two groups was performed via a questionnaire. RESULTS: The total effective rate of patients in the observation group was higher after hydration treatment (97.87% vs 87.23%, p< 0.05). The blood urea nitrogen, creatinine, and ß2 microglobulin levels in the observation group were significantly lower than those in the control group after the intervention (p< 0.05). Patients in the observation group had higher nursing satisfaction after using preventive measures of hydration therapy combined with nursing interventions (100% vs 89.36%, p< 0.05). CONCLUSION: Hydration therapy and nursing intervention can effectively prevent CIN after interventional treatment of lower extremity ASO. After interventional therapy, patients had better clinical outcomes, lower biochemical indexes and improved satisfaction evaluations. The therapy is worthy of clinical promotion and application.
RESUMEN
Introduction: Orthotopic kidney transplantation is an option when heterotopic kidney transplantation into the iliac fossa is inappropriate. We report a case of orthotopic kidney transplantation following stenting of both external iliac arteries to treat arteriosclerosis obliterans. Case presentation: A 56-year-old woman on hemodialysis for end-stage kidney disease underwent living-donor kidney transplantation. Desensitization therapy was administered because of her history of sensitization by pregnancy. Stents had been placed previously in both external iliac arteries. The left kidney was removed via an oblique lumbar incision. The two graft arteries were conjoined and anastomosed to the native renal artery end-to-end. The urinary tract was reconstructed by uretero-ureterostomy with ureteral stent placement. Renal function improved promptly after surgery. Conclusion: Preoperative imaging of vascular anatomy is important for successful orthotopic kidney transplantation in patients who have previously undergone stenting of both external iliac arteries for arteriosclerosis obliterans.
RESUMEN
An increasing number of studies have shown that noncoding RNAs are involved in cardiovascular diseases. Our study shows that the expression of microRNA-30a-3p (miR-30a-3p) in patients with arteriosclerosis obliterans (ASO) of the lower extremities is significantly decreased after endovascular treatment, but its role is unclear. This study aims to explore the role of microRNA-30a-3p in ASO and its related mechanisms. Immunofluorescence and in situ hybridization costaining indicated that microRNA-30a-3p mostly exists in vascular smooth muscle cells (VSMCs). Furthermore, after transfection into VSMCs, microRNA-30a-3p inhibited VSMC proliferation, migration and phenotype switching. In addition, luciferase reporter and western blot analyses indicated that ROCK2 (Rho-related spiral coil 2 containing protein kinase) is a microRNA-30a-3p target gene, and participates in the microRNA-30a-3p mediated cell inhibitory effect. At last, the rat carotid artery was infected by lentivirus after balloon injury, which increased microRNA-30a-3p levels and apparently suppressed the formation of neointima in vivo. Overall, exogenous introduction of microRNA-30a-3p, a noncoding RNA with unlimited potential, may be a new approach to treat ASO.

Background: Arteriosclerosis obliterans (ASO) is the leading cause of nontraumatic lower-extremity amputations. Multiple researches have suggested that circular RNAs (circRNAs) played vital regulatory functions in cancer and cardiovascular disease. Nevertheless, the underlying effect and pathological mechanism of circRNAs in the formation and progression of ASO are still indistinct. Methods and Results: This study used microarray analysis to investigate the expression portrait of circRNAs in normal lower extremity arteries and ASO arteries. Bioinformatics analysis was conducted using the KEGG database to study the enrichment of differentially expressed circRNAs (DE circRNAs) and predict their functions. The accuracy of microarray assay was verified by evaluating expression of the top 5 upregulated and 5 downregulated circRNAs (raw density of normal group ≥200) using RT-qPCR. A circRNA-miRNA-mRNA interaction network was further predicted using software. Compared to the normal lower extremity group, the ASO arteries with HE and EVG staining presented hyperplastic fibrous membrane and luminal stenosis. A total of 12,735 circRNAs were identified, including 1196 DE circRNAs with 276 upregulated and 920 downregulated in ASO group based on |log2(FC)| > 1 and padj < 0.05. Among selected 10 circRNAs, RT-qPCR confirmed that hsa_circ_0003266, hsa_circ_0118936 and hsa_circ_0067161 were upregulated while hsa_circ_0091934 and hsa_circ_0092022 were downregulated in ASO group (p < 0.05). GO analysis presented that the DE circRNAs were primarily enriched in protein binding, intracellular part and organelle organization. KEGG pathway analysis indicated that MAPK signaling pathway, human T-cell leukemia virus 1 infection, proteoglycans in cancer were associated with the DE circRNAs. The circRNA-miRNA-mRNA interactive network revealed that both mRNAs and miRNAs linked to circRNAs played an indispensable role in ASO. Conclusion: This study described the expression portrait of circRNAs in human ASO arteries, and revealed the molecular background for further investigations of the circRNA regulatory mechanism in the formation and progression of ASO.
RESUMEN
OBJECTIVE: To explore the effect of a health (E)-coach chronic disease management model on the rehabilitation behaviour management of patients with arteriosclerosis obliterans (ASO). METHODS: The E-coach chronic disease management model was constructed based on a literature review and expert interviews. The effect of the E-coach model on patients with ASO during hospitalisation was analysed by comparing the compliance rates of blood glucose control, blood pressure control, drug compliance, ankle-brachial index, 6-min walking test (6MWT) and pain-free walking distance (PFWD) scores between the E-coach and control groups. RESULTS: In total, 212 patients with ASO were included in this study. After the intervention, the blood pressure compliance rate (44.8% vs. 65.7%) and blood glucose compliance rate (48.6% vs. 66.8%) were higher in the E-coach group than in the control group (p < 0.05). After intervention, compared with the control group, the patients in the E-coach group had better drug compliance (6.8 ± 1.9 vs. 7.9 ± 1.0), and the difference was statistically significant (p < 0.05). The scores for the 6MWT (329.19 ± 5.58 vs. 353.00 ± 9.76; 412.65 ± 12.59 vs. 499.16 ± 18.43) and PFWD (219.15 ± 11.96 vs. 225.36 ± 16.13; 331.62 ± 51.36 vs. 369.42 ± 75.71) tests were significantly higher in the E-coach group than in the control group at 1 and 6 months after intervention (p < 0.05). CONCLUSION: The E-coach chronic disease management model can effectively improve the control rates of blood glucose and blood pressure and the behaviour management of patients with ASO and is thus worthy of clinical reference.

Objective: Our study aims to investigate the long non-coding RNA plasmacytoma variant translocation 1 (lncRNA PVT1) in lower extremity arteriosclerosis obliterans (LEASO) patient serum and its clinical significance in LEASO. Patients and Methods: From July 2021 to April 2022, 133 LEASO patients diagnosed at the Qingdao Municipal Hospital were included. Among them, 44 complicated with coronary artery disease (CAD) were classified as the LEASO with CAD group. The remaining 89 were marked as the LEASO group, which was classified into single (n = 48) and double (n = 41) lower limb groups, with the former being subclassified into the left (n = 28) and right (n = 20) lower limb groups based on the affected sites. Fifty healthy individuals who came to our hospital for physical examination during the same period were randomly included and defined as the Healthy Control group. PVT1 expression was detected in serum samples from each group using a quantitative reverse transcriptase-polymerase chain reaction , and differences in expression levels were calculated. The ankle-brachial index (ABI) of patients in the LEASO group was measured using a sphygmomanometer, and its correlation with PVT1 was analyzed. Clinical data and laboratory test results (including blood routine, liver and renal function, and blood lipids) were collected for all patients upon admission. Logistic regression analyses were performed to determine the influence of PVT1 and laboratory test results on LEASO. The diagnosis and prediction of LEASO were obtained by combing PVT1 with laboratory test indicators. Results: It was found that lncRNA PVT1 expression was the highest in the serum of the LEASO with CAD group, followed by the LEASO and control groups (P < 0.05). Within the LEASO group, no significant difference in PVT1 expression was seen between the left and right limbs (P > 0.05), nor between the single and double lower limb groups. Furthermore, the PVT1 expression increased with the Rutherford grades, indicating a negative correlation between PVT1 and ABI. Logistic regression analysis revealed that triglycerides (OR = 2.972, 95% CI [1.159-7.618]), cholesterol (OR = 6.655, 95% CI [1.490-29.723]), C-reactive protein (OR = 1.686, 95% CI [1.218-2.335]), and PVT1 (OR = 2.885, 95% CI [1.350-6.167]) were independent risk factors for LEASO. Finally, strong sensitivity was observed in the receiver operating characteristic curve when combining PVT1 with meaningful laboratory indicators to diagnose and predict LEASO. Conclusion: lncRNA PVT1 promotes LEASO occurrence and progression and is related to atherosclerosis severity. The expression of PVT1 was negatively correlated with ABI. Logistic regression analysis suggested that blood lipid levels and inflammatory reactions might be related to LEASO occurrence. PVT1 was incorporated into laboratory indicators to predict LEASO. The subject's working curve area was large, and the prediction results were highly sensitive.

INTRODUCTION: Patients with peripheral arterial disease (PAD) have a poorer prognosis than those without PAD. PAD complications worsen the prognosis of patients with chronic kidney disease (CKD), especially those on maintenance dialysis. Although low-density lipoprotein apheresis (LDL-A) is expected to be effective in treating severe PAD, there are no large-scale reports on the prognosis of patients undergoing LDL-A. METHODS: We obtained a clinical database from April 2008 to August 2021 and selected 924 238 patients with CKD. We selected patients with disease codes of lower limb arteriosclerosis obliterans, arteriosclerosis obliterans, and critical limb ischemia or foot ulcer. Patients who were prescribed antithrombotic medications were included. Patients who used steroids were excluded. Among these patients, those undergoing blood purification considered LDL-A were selected, and their current status was investigated. RESULTS: We included 147 patients (113 males and 34 females). The mean patient age was 70 ± 10 years. Diabetes mellitus was present in 86%, ischemic heart disease in 34%, and stroke in 48%. Maintenance dialysis patients accounted for 86% of the patients. Statins were administered to 40% of the patients, and bypass surgery was performed in 2.7%. The median observation period was 812 days, and the mortality rate was 41%. CONCLUSION: LDL-A was performed in a small population of patients with CKD with the most severe form of PAD. The prognosis for these patients is extremely poor. Therefore, strategies to improve prognosis are important.
