RESUMO

Background: There are several procedural variations for kidney transplant donors, including open, laparoscopic, hand-assisted, and robotic methods, with either an intra- abdominal or retroperitoneal approach. Conversely, fewer options are available for the recipient procedure. We introduce a method that involves a small incision, with the goal of being less invasive for recipients. Methods: Our current method was introduced in April 2022. As of July 2023, we have completed 27 cases. We analyzed several factors in these 27 cases, including the size of the incision, rewarming time, anastomosis time, graft function, analgesic use, and complications. Results: The average incision size was 73 mm. The time taken for anastomosis was 24. 1 minutes, while the rewarming time averaged 43.1 minutes. There were no instances of primary nonfunction. One case necessitated postoperative dialysis three times due to heart failure. Following stent removal, one patient developed grade 1 hydronephrosis. There was one instance of bleeding from the drain insertion site. Another case involved a clamp injury to the external iliac artery, which necessitated stent insertion on the fourth postoperative day. Compared to procedures performed using conventional methods, the use of analgesics was less in these cases. Conclusions: Our minimally invasive technique, which involves a small incision, is a feasible alternative that could potentially be less invasive than traditional methods.

RESUMO

Some asymptomatic patients with diabetes mellitus (DM) have critical coronary artery disease (CAD), although the guidelines do not recommend aggressive screening for CAD in asymptomatic patients. Chronic kidney disease (CKD) is among the serious co-morbidities of severe systemic atherosclerosis. Thus, CKD may be associated with potential myocardial ischaemia. Therefore, the present study aimed to determine the impact of CKD on the incidence of silent myocardial ischaemia (SMI) and the long-term outcomes in asymptomatic patients with DM. This study investigated 461 consecutive patients with DM. All patients who were asymptomatic and self-sufficient in daily life underwent the ergometer exercise (ERG) test. Coronary angiography was performed if the stress test was positive, or if the patient did not achieve 90% of the target heart rate. The primary end point included major adverse cardiac and cerebrovascular events (MACCE) including death, non-fatal myocardial infarction and stroke. The median follow-up duration after study enrolment was 35 months for the entire cohort of 461 patients. Eighty-one patients were diagnosed with SMI. The estimated glomerular filtration rate was significantly lower in the SMI group (70.5 ± 23.8 vs. 81.8 ± 30.0 mL/min/1.73 m2, P < 0.001). SMI occurred more frequently in patients with advanced CKD [27/103, (26.2%) in stages 3-5], whereas only 5/68 (7.3%) patients without CKD, 13/81 (16.0%) patients with stage 1 CKD and 36/209, (17.2%) in stage 2, had SMI. The Kaplan-Meier curves revealed that, patients with SMI had poor clinical outcomes (log-rank: P = 0.016). The incidence of MACCE (log-rank: P = 0.009) was higher in patients with severe CKD > stage 3a in the SMI subgroup. Urinary albumin (mg/gCr) was associated with MACCE in the SMI subgroup [HR 3.37, 95%CI (1.170-9.521), P = 0.025] after adjusting for age, sex, and conventional risk factors. SMI was more prevalent in patients with CKD and the incidence was proportional to the CKD stage in asymptomatic patients with DM. Those Patients with CKD and SMI exhibited poor clinical outcomes. CKD may be a key factor for the identification and management of SMI in asymptomatic patients with DM in routine clinical practice.Trial Registration: UMIN000038340.

RESUMO

BACKGROUND: The long-term safety and utility of intravascular ultrasound (IVUS)-guided zero-contrast percutaneous coronary intervention (PCI) in patients with chronic kidney disease (CKD) are unknown.Methods and Results: A total of 698 consecutive patients treated with PCI (1,061 procedures) in our center were studied. Patients with acute coronary syndrome, who are on maintenance hemodialysis, and who had a planned rotational atherectomy were excluded. Finally, they were divided into 2 groups: zero-contrast PCI (n=55, 78 procedures) and conventional PCI (n=462, 670 procedures). After propensity score matching, 50 patients were matched for each group to evaluate long-term outcomes. Primary endpoints were major adverse cardiovascular events (MACE), including all-cause death, non-fatal myocardial infarction (MI), and clinically driven target lesion revascularization. All patients in the zero-contrast PCI group had stage 3-5 CKD with an estimated glomerular filtration rate of 38.3±14.8 mL/min/1.73 m2. Zero-contrast PCI was successful in all 78 procedures without renal events such as acute kidney injury or emergent hemodialysis and procedural complications such as coronary perforation or periprocedural MI. During a follow-up period of 32 months, 7 patients died (1 cardiac, 6 non-cardiovascular), and 4 patients were introduced to renal replacement therapy. The incidence of MACE was similar between the zero-contrast and conventional PCI groups (log-rank, P=0.95). CONCLUSIONS: IVUS-guided zero-contrast PCI might be safe and feasible in patients with CKD with satisfactory acute and long-term renal and cardiovascular outcomes.

RESUMO

Although several studies have shown that release of water channel proteins, aquaporin 1 (AQP1) and AQP2 in urinary extracellular vesicles (uEV-AQP1 and -AQP2), were altered in experimental kidney injury models, their release in human chronic kidney disease (CKD) has been largely unexplored. The aim of the present study was to clarify whether the release of uEV-AQP1 and -AQP2 is altered in patients with CKD. Urine samples were collected from 15 healthy volunteers (normal group) and 62 CKD patients who were categorized into six glomerular filtration rate (GFR) categories (G1, G2, G3a, G3b, G4, and G5) in between 2005 and 2016 at Miyazaki Prefectural Miyazaki Hospital, Japan. uEV-proteins were evaluated by immunoblot analysis. The release of AQP1 and AQP2 were significantly decreased in patients with both CKD G4 and G5, in comparison with the normal group. The area under the receiver operating characteristic (ROC) curve (AUC) values for AQP1 and AQP2 in patients with CKD G4 and G5 were 0.926 and 0.881, respectively. On the other hand, the AUC values in patients with CKD G1-G3 were 0.512 for AQP1 and 0.680 for AQP2. Multiple logistic regression analysis showed that AQP1 and AQP2 in combination were useful for detecting CKD G4 and G5, with a higher AUC value of 0.945. These results suggest that the release of uEV-AQP1 and -AQP2 was decreased in patients with CKD G4 and G5, and these proteins might be helpful to detect advanced CKD.

RESUMO

BACKGROUND: Left atrial (LA) volume and left ventricular longitudinal strain (LVLS) have significant prognostic values for major cardiovascular events (MACEs). Prognostic values of LA reservoir functional indices measured by 3-dimensional (3D) speckle-tracking echocardiography (STE) were evaluated.Methods and Results:A total of 264 patients, who underwent 2-dimensional (2D) echocardiography and 3DSTE for various underlying heart diseases, were followed up to record MACE. After a mean follow up of 547±435 days, 30 patients developed MACE: 7 cardiac deaths, 6 strokes, 1 non-fatal myocardial infarction, and 22 admissions for heart failure (5 of these had cardiac death after discharge, whereas 1 sustained stroke after discharge). Receiver operating characteristic curve analysis was performed to determine the optimal cut-off levels of 4 LA functional indices: LA emptying fraction (LAEmpF), LA longitudinal strain (LALS), LA circumferential strain (LACS), and LA area change ratio (LAAC), using 3DSTE. Among these factors, 2DLVLS, 3DLAEmpF, and 3DLALS demonstrated a higher hazard ratio (>5.0) than other variables. The 3DLAEmpF and 3DLALS had a higher average treatment effect (ATE) and ATE on the treated (ATT), respectively, than the other indices after propensity score matching. Addition of 3DLAEmpF to the base model using clinical variables and LV ejection fraction or 2DLVLS demonstrated higher prognostic power. CONCLUSIONS: LAEmpF calculated using 3DSTE possessed additive prognostic values for the prediction of MACE.

RESUMO

BACKGROUND: Diabetic patients often have coronary artery disease (CAD) without symptoms. It is known that females tend to have silent or less chest pain and worse prognoses when they develop acute coronary syndrome. Thus, sex differences may impact long-term outcomes in diabetes mellitus (DM) patients with silent myocardial ischemia (SMI). The present study aimed to assess the influence of sex on long-term outcomes in DM patients with SMI. METHODS: A total of 461 consecutive asymptomatic and self-sufficient DM patients seen at our hospital from 2011 to 2017 were prospectively reviewed. Patients underwent an ergometer exercise test. When the exercise test was positive or the patient could not achieve 90% of their target heart rate, coronary angiography was performed. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCEs), including death, non-fatal myocardial infarction, and stroke. RESULTS: SMI was diagnosed in 81 patients. The median follow-up duration from diagnosis was 35 (15-57) months. The incidence of SMI was similar in females and males [34/170 (20%) vs. 47/291 (16.2%), p = 0.36]. Enrolled patients were divided into four groups according to sex and the presence/absence of SMI. Female patients with SMI showed worse clinical outcomes. After adjustment for age and coronary risk factors, female SMI was independently associated with MACCEs [hazard ratio 2.59, 95% confidence interval 1.07-5.68, p = 0.024], while male SMI was not. CONCLUSIONS: Female SMI was associated with worse long-term outcomes in DM patients. Early diagnosis of potential SMI and appropriate care are required in female DM patients. (UMIN000038340).

RESUMO

BACKGROUND: New guidelines from The Society of Thoracic Surgeons recommend adding surgical ablation as a concomitant procedure for class I indications. We performed the maze procedure for all patients who experienced atrial fibrillation (AF) before cardiac surgery, without surgeon pre-exclusion. METHODS: We retrospectively analyzed 83 patients, aged 71 ± 11 years (22% >80 years), who underwent Cox maze IV for persistent AF between 2014 and 2017. The mean AF duration (AFD) was 6.9 ± 8.6 years and European System for Cardiac Operative Risk Evaluation II was 7.2 ± 6.8. RESULTS: The 30-day mortality was 2.4%. During follow-up (mean, 675 days), the 1-, 2-, and 3-year survival rates were 92%, 86%, and 82%, respectively. No strokes were observed despite a mean CHA2DS2-VASC (Congestive heart failure, Hypertension, Age [≥65 = 1 point, ≥75 = 2 points], Diabetes, and Stroke/transient ischemic attack [2 points], vascular disease, Sex [female = 1 point]) score of 4.1 (expected stroke rate, 4%/y). Twelve patients required a new pacemaker; 56 of 73 survivors (77%) remained AF free. Multivariate logistic regression identified preoperative AFD, f wave size, and mean heart rate per Holter as important risk factors for AF recurrence, with AFD as the most important: 98% of patients with AFD less than 5 years remained AF free. Although the AF-free rate with the AFD of 5 or more years was only 55%, their symptoms improved without heart failure readmission. Concomitant atrial plication was performed more frequently in the group with AFD for 5 or more years, with greater atrial volume reduction and appreciable increases in stroke volume. CONCLUSIONS: The Cox maze IV procedure performed without pre-exclusion showed reasonable survival rates. Although AF recurred in patients with longer AFD, they fared well with substantial increases in stroke volume. Concomitant atrial volume reduction may have contributed to these additional benefits.

RESUMO

Acid-catalyzed intramolecular Friedel-Crafts cyclization of optically active α-hydroxy-α-alkenylsilanes possessing a benzene ring (>99% ee) with TMSOTf as a Lewis acid gave enantio-enriched tetrahydronaphthalenes (up to 98% ee). The silyl group attached to the chiral carbon played a crucial role in the chirality transfer.

RESUMO

BACKGROUND: Diuresis has been observed within a week following renal transplantation, suggesting that the procedure causes acute disturbance of renal water homeostasis. Aquaporin (AQP) 1 and AQP2, important proteins for renal water reabsorption, have been identified in urinary extracellular vesicles (uEV-AQP1 and -AQP2), and experimental studies have shown that the presence of uEV-AQP1 and -AQP2 may be an indicator of their levels of expression in the kidney. However, the release patterns of uEV-AQP1 and -AQP2 during the acute phase following renal transplantation are largely unknown. METHODS: In this study, we examined the release of uEV-AQP1 and -AQP2 in recipients until 6 days (day 6) after renal transplantation. At Miyazaki prefectural Miyazaki Hospital, Japan, uEVs were obtained from 7 recipients, all of whom had received renal allografts from living donors. uEVs were isolated by differential centrifugation. RESULTS: Immunoblotting analysis showed that the release of uEV-AQP2 was significantly decreased on day 1 in comparison with a control sample (from 3 healthy volunteers), accompanied by high urine output and low urine osmolality. Thereafter, the level increased gradually to the control level by day 6. The release pattern of uEV-AQP1 was similar to that of uEV-AQP2, but the levels did not reach statistical significance in comparison with the control level at any of the time points examined. Evaluation of the relationship between urinary osmolality and uEV-AQPs revealed a significant correlation for uEV-AQP2, but not for uEV-AQP1. CONCLUSION: These results indicate that acute diuresis after renal transplantation might be due to a decrease in the renal expression of AQP2, whose level can be estimated from the amount released in uEVs.

RESUMO

BACKGROUND: The prognostic value of indices for left atrial volumes (LAV) and reservoir function measured by 3D speckle-tracking analysis (3DSTA) has not been determined. Methods and Results: LA maximal and minimal volume indices (LAVImax, LAVImin), and LA emptying fraction (LAEmpF) were measured via 2D echocardiography (2DE) and 3DSTA in 514 patients (62% male, mean age: 66±15 years) with various cardiovascular diseases. Two cutoff values using normal±2SD (cutoff criterion 1) and receiver-operating characteristic analysis (cutoff criterion 2) were evaluated. During a mean follow-up of 720±383 days, MACE (cardiac death, nonfatal myocardial infarction, stroke and admission for heart failure) occurred in 98 patients. Kaplan-Meier survival analysis showed both cutoff criteria measured by 2DE and 3DSTA had significant predictive power for MACE (P<0.001). For cutoff criterion 1, 3DSTA measurements yielded higher hazard ratios than 2DE by Cox proportional hazard model. Cutoff criterion 2 using 3DSTA had higher average treatment effect values than 2DE by matching propensity scores on the outcome. Further, a regression model that included clinical variables, left ventricular ejection fraction and cutoff criterion 2 using 3DSTA-derived LAEmpF had significantly higher prognostic power than 2DE. CONCLUSIONS: LA indices measured by 3DSTA had greater prognostic power for future MACE than 2DE. In particular, 3DSTA-derived LAEmpF has the potential to be a valuable prognostic tool in clinical settings.

RESUMO

BACKGROUND: The ideal surgical technique for ischemic mitral regurgitation (MR) is controversial. We introduced an extended posterior mitral leaflet (PML) augmentation technique for functional MR with severe tethering, which detached the PML from the annulus almost completely and augmented it with a large 3×6-cm oval pericardial patch. Methods and Results: A total of 17 mitral repairs using the new technique were performed for ischemic MR with no 30-day mortality and 2 hospital deaths. The NYHA class was III in 47% and IV in 13%. The EuroSCORE II was 9.7±4.9. The ring size was 32±1.4 mm. Concomitant coronary bypass was performed in 67% and left ventricular repair in 28%. The mechanism of leaflet closure was evaluated using transthoracic echocardiography in 15 survivors. MR decreased to none or trivial with a significant increase in coaptation length (Pre: 4.6±0.8 mm vs. Post: 9.8±2.5 mm; P<0.001). The PML flexibly moved forward and tightly contacted as if "snuggling up" to the anterior leaflet. There were no late deaths, heart failure readmissions or MR recurrences during follow-up (850±181 days). All patients remained in NYHA I or II. CONCLUSIONS: Extended PML augmentation for ischemic MR showed excellent early results with deep leaflet coaptation through a "snuggling up" phenomenon, which would help prevent late MR recurrence.

RESUMO

We present the cases of eight patients (mean age 75 years; EuroSCORE II 17.0 ± 22.0) who underwent post-cardiotomy venovenous extracorporeal membrane oxygenation (ECMO) without heparinization due to serious bleeding. Three liver cirrhosis, two chronic hemodialysis, three redo sternotomy, and two urgent surgery cases were included. Respiratory ECMO Survival Prediction score was - 5.1 ± 4.2 (estimated survival rate: approximately 30%). Mean ECMO duration was 14 days with 9 circuit exchanges. Five patients were weaned from ECMO and three were discharged alive at 90 days (survival 37.5%). There was a case of pump-head thrombosis requiring urgent circuit exchange. All experienced bleeding complications without clinically apparent pulmonary thromboembolism. Disseminated Intravascular Coagulation scores (Pre 1.3 ± 0.8 vs. Post 3.8 ± 1.7; p < 0.05) significantly increased (N = 6). Post-cardiotomy ECMO without heparinization facilitated patient rescue at a reasonable survival rate. However, bleeding complications were still observed. More sophisticated management protocols are warranted.

RESUMO

Anderson-Fabry disease is a rare X-linked lysosomal storage disease caused by α-galactosidase A (α-GalA) gene variants and characterized by a large genotypic and phenotypic spectrum. Enzyme replacement therapy (ERT) using recombinant α-GalA has been approved for > 10 years as a specific therapy for the disease. However, the long-term clinical efficacy for cardiac manifestations has been equivocal because it depends on several factors such as genotype, sex, age, and disease severity at the initiation of ERT. We report the differences in the clinical effects of ERT continued for > 10 years in three patients with the same genotype. Left ventricular hypertrophy and myocardial dysfunction progressed in the heterozygote proband even under ERT, although disease progression was prevented in two sons of Case 1.

RESUMO

Although surgical left atrial (LA) volume reduction combined with mitral valve surgery and/or surgical ablation for atrial fibrillation has been reported to be effective, its long-term outcomes in the absence of mitral procedure are not well established. A 74-year-old man with two previous sternotomies-the first for pericardiectomy due to constrictive pericarditis and the second for mitral valve replacement with mechanical valve and tricuspid annuloplasty-presented with heart failure and thrombus in his giant left atrium (1291 mL), complicated by cerebral infarction. His electrocardiogram showed rate-controlled persistent atrial fibrillation. His mechanical valve was functioning well. A third atrial volume reduction combined with pulmonary vein isolation, without valve surgery, was performed. The postoperative course was uneventful, and the patient has remained asymptomatic with regular junctional rhythm and without any episodes of thromboembolism or re-dilation of LA (approximately 550 mL). His left ventricular filling improved with end-diastolic volume (96 mL vs 140 mL) and forced vital capacity (2.60 L vs 2.89 L) increased. Both remained relatively constant for 6 years. The combination of atrial volume reduction with pulmonary vein isolation prevented thromboembolism, improved left ventricular filling, and continued to improve symptoms associated with heart failure and respiratory condition for 6 years. .

RESUMO

Acute kidney injury (AKI) is an important risk factor for the development of chronic kidney disease (CKD), and an alteration in renal water handling has been observed during the transition of AKI to CKD. Urinary exosomal release of aquaporin-1 (AQP1) and AQP2, important proteins for renal water handling, has recently been reported to predict their levels of renal expression. Therefore, we examined the patterns of urinary exosomal release of AQP1 and AQP2, and the exosomal marker proteins tumor susceptibility 101 protein (TSG101) and ALG-2 interacting protein X (Alix), in the acute and chronic phases following induction of AKI by renal bilateral ischemia/reperfusion (I/R) in rats. Blood tests and histological examinations indicated that AKI occurred before at 7 days after renal I/R ( day 7) and that renal fibrosis developed progressively thereafter. Immunoblotting demonstrated significant decreases in the urinary exosomal release of AQP1 and AQP2 during severe AKI. Urinary exosomal release of Alix and TSG101 was significantly increased on day 7. These data were also confirmed in rats with unilateral renal I/R causing more serious AKI. Urinary exosomal release of either the Ser-256- or Ser-269-phosphorylated form of AQP2, both of which are involved in apical trafficking of AQP2, was positively correlated with that of total AQP2. These results suggest that urinary exosomal release of AQP1 and AQP2 is reduced in I/R-induced AKI, whereas that of Alix and TSG101 is increased in the initial phase of renal fibrosis. Furthermore, apical trafficking of AQP2 appears to be related to urinary exosomal release of AQP2.

RESUMO

BACKGROUND: Little information is available on non-cardiovascular (CV) death in acute heart failure (AHF) patients. The present study determined the incidence, time course, and factors associated with long-term non-CV death in AHF patients in a real-world setting. METHODS: The ATTEND registry, a nationwide, prospective observational multicenter cohort study, included 4842 consecutive patients hospitalized for AHF. The primary endpoint of the present study was non-CV death. RESULTS: Median follow-up duration from admission was 513 (range, 385-778) days. Over the study period, 1183 patients died; 356 deaths (30.1%) were non-CV related. The proportion of non-CV deaths increased in the later follow-up phase (0-180days, 26.7%; 181-360days, 38.4%; >360days, 36.6%, p<0.001). After adjustment for all variables at baseline, age (hazard ratio [HR] 1.6 per decade, p<0.001) and non-cardiac comorbidities including chronic obstructive pulmonary disease (HR 1.58, p=0.003), history of stroke (HR 1.44, p=0.011), renal insufficiency (HR 1.07, per 10ml/min/1.73m2 decrease in estimated glomerular filtration, p=0.015), and hemoglobin (HR 1.15 per 1.0g/dl decrease, p<0.001) were strongly associated with non-CV death. Other predictors included ischemic etiology (HR 1.33, p=0.023), prior hospitalization for heart failure (HR 1.34, p=0.017), C-reactive protein (HR 1.04, p<0.001), and statin use (HR 0.70, p=0.016). CONCLUSIONS: The incidence of non-CV death was high in patients with AHF, accounting for 30% of long-term mortality. Furthermore, the proportion of non-CV death increased in the later follow-up phase. Better understanding of non-CV death and more comprehensive treatment of non-CV comorbidities are vital to further improving prognosis in AHF patients.

RESUMO

OBJECTIVE: Despite the remarkable advances in chemotherapy and allogeneic hematopoietic stem cell transplantation (HSCT), adult T-cell leukemia-lymphoma (ATL) is still associated with a high mortality rate. It is therefore essential to elucidate the current features of ATL. METHODS: We retrospectively analyzed 81 patients with aggressive type ATL at our institution over a 7-year period based on Shimoyama's diagnostic criteria. RESULTS: Eighty-one patients with a median age of 67.5 years were classified as having acute (n=47), lymphoma (n=32), or chronic type (n=2) ATL. They were initially treated by either palliative therapy (n=25) or systemic chemotherapy [n=56; cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) therapy (n=25)/vincristine, cyclophosphamide, doxorubicin, and prednisone (VCAP)-doxorubicin, ranimustine, and prednisone (AMP)-vindesine, etoposide, carboplatin, and prednisone (VECP) therapy (VCAP-AMP-VECP) or CHOP-VMMV therapy (n=31)], and showed median survival durations of 16 and 277 days, respectively. Subsequent to the initial treatment, HSCT (n=6) was performed for certain patients, thus revealing that two-thirds (n=4) relapsed, and one-third (n=2) survived for 131 days and 203 days, respectively. The relapsed ATL patients were treated with conventional salvage therapy (n=29) or anti-CC chemokine receptor 4 antibody (mogamulizumab) (n=3). The patients treated with mogamulizumab demonstrated complete response (2) and partical response (1) with short duration periods of 82 days, 83 days, and 192 days, respectively. Among the five long-term survivors (>5 years) who received chemotherapy, most showed a low and intermediate risk according to the ATL prognostic index. CONCLUSION: In our study, the overall survival of ATL remains poor due to the advanced age of the patients at diagnosis, a high proportion of patients receiving palliative therapy, and a small proportion of long-term survivors receiving chemotherapy and undergoing HSCT. This study illustrates the current clinical features, treatment strategies, and outcomes in clinical practice.

RESUMO

OBJECTIVE: Disseminated intravascular coagulation (DIC) is a clinical condition with high mortality that is characterized by the systemic activation of coagulation pathways resulting in multiple organ failure. Although no standard treatment for DIC has been established, recent reports have indicated that recombinant human soluble thrombomodulin (rTM) is effective against DIC. METHODS: To elucidate the clinical characteristics and outcomes of DIC, we retrospectively analyzed 92 DIC patients who were treated with rTM at Miyazaki Prefectural Hospital over a 4-year period (62 patients had infectious diseases and 30 patients had hematological diseases). A diagnosis of DIC was made based on the diagnostic criteria of the Japanese Association for Acute Medicine (JAAM) and Japanese Ministry of Health and Welfare (JMHW) for infectious diseases and hematological diseases, respectively. In addition to treating the underlying disease, rTM was administered for six consecutive days. RESULTS: In this study, 49 of the 92 DIC patients (53.3%) experienced resolution of DIC seven days after administration (46.8% patients with infectious disease and 66.7% with hematological disease). A higher survival rate was observed after a 28-day observation period in 69 of the 92 patients (75.0%) (72.6% of the patients with infectious disease and 80.0% of the patients with hematological disease). A lower DIC score at the initiation of rTM treatment was closely related to a higher rate of resolution of DIC. CONCLUSION: Our findings indicate that rTM therapy is an effective, safe and feasible treatment for DIC patients. Furthermore, making an accurate and early diagnosis of DIC and providing subsequent immediate treatment with rTM may improve the resolution of DIC.
