RESUMEN
BACKGROUND: The rebleeding risks and outcomes of endoscopic treatment for acute lower gastrointestinal bleeding (ALGIB) may differ depending on the bleeding location, type, and etiology of stigmata of recent hemorrhage (SRH) but have yet to be fully investigated. We aimed to identify high risk endoscopic SRH and to propose an optimal endoscopic treatment strategy. METHODS: We retrospectively analyzed 2699 ALGIB patients with SRH at 49 hospitals (CODE BLUE-J Study), of whom 88.6â% received endoscopic treatment. RESULTS: 30-day rebleeding rates of untreated SRH significantly differed among locations (left colon 15.5â% vs. right colon 28.6â%) and etiologies (diverticular bleeding 27.5â% vs. others [e.âg. ulcerative lesions or angioectasia] 8.9â%), but not among bleeding types. Endoscopic treatment reduced the overall rebleeding rate (adjusted odds ratio [AOR] 0.69; 95â%CI 0.49-0.98), and the treatment effect was significant in right-colon SRH (AOR 0.46; 95â%CI 0.29-0.72) but not in left-colon SRH. The effect was observed in both active and nonactive types, but was not statistically significant. Moreover, the effect was significant for diverticular bleeding (AOR 0.60; 95â%CI 0.41-0.88) but not for other diseases. When focusing on treatment type, the effectiveness was not significantly different between clipping and other modalities for most SRH, whereas ligation was significantly more effective than clipping in right-colon diverticular bleeding. CONCLUSIONS: A population-level endoscopy dataset allowed us to identify high risk endoscopic SRH and propose a simple endoscopic treatment strategy for ALGIB. Unlike upper gastrointestinal bleeding, the rebleeding risks for ALGIB depend on colonic location, bleeding etiology, and treatment modality.

This study examined the effects of intrathecal analgesia (ITA) using an extracorporeal pump with a subcutaneous port system in cancer patients with bone metastasis. Among the patients who died of cancer with bone metastasis at the palliative care unit of our institution, 11 who received ITA were selected. Changes in pain, opioid doses, the palliative prognostic index (PPI), and Eastern Cooperative Oncology Group Performance Scaleãafter ITA were assessed. Pain, opioid doses, and PPI decreased after ITA (P = 0.002, 0.002, and 0.017). ITA for cancer patients with increased PPI due to refractory cancer bone pain decreased pain, opioid doses, and PPI.(100 words).

BACKGROUND & AIMS: Currently, large, nationwide, long-term follow-up data on acute lower gastrointestinal bleeding (ALGIB) are scarce. We investigated long-term risks of recurrence after hospital discharge for ALGIB using a large multicenter dataset. METHODS: We retrospectively analyzed 5048 patients who were urgently hospitalized for ALGIB at 49 hospitals across Japan (CODE BLUE-J study). Risk factors for the long-term recurrence of ALGIB were analyzed by using competing risk analysis, treating death without rebleeding as a competing risk. RESULTS: Rebleeding occurred in 1304 patients (25.8%) during a mean follow-up period of 31 months. The cumulative incidences of rebleeding at 1 and 5 years were 15.1% and 25.1%, respectively. The mortality risk was significantly higher in patients with out-of-hospital rebleeding episodes than in those without (hazard ratio, 1.42). Of the 30 factors, multivariate analysis showed that shock index ≥1 (subdistribution hazard ratio [SHR], 1.25), blood transfusion (SHR, 1.26), in-hospital rebleeding (SHR, 1.26), colonic diverticular bleeding (SHR, 2.38), and thienopyridine use (SHR, 1.24) were significantly associated with increased rebleeding risk. Multivariate analysis of colonic diverticular bleeding patients showed that blood transfusion (SHR, 1.20), in-hospital rebleeding (SHR, 1.30), and thienopyridine use (SHR, 1.32) were significantly associated with increased rebleeding risk, whereas endoscopic hemostasis (SHR, 0.83) significantly decreased the risk. CONCLUSIONS: These large, nationwide follow-up data highlighted the importance of endoscopic diagnosis and treatment during hospitalization and the assessment of the need for ongoing thienopyridine use to reduce the risk of out-of-hospital rebleeding. This information also aids in the identification of patients at high risk of rebleeding.

AIM: No studies have compared the clinical outcomes of early and delayed feeding in patients with acute lower gastrointestinal bleeding (ALGIB). This study aimed to evaluate the benefits and risks of early feeding in a nationwide cohort of patients with ALGIB in whom haemostasis was achieved. METHODS: We reviewed data for 5910 patients with ALGIB in whom haemostasis was achieved and feeding was resumed within 3 days after colonoscopy at 49 hospitals across Japan (CODE BLUE-J Study). Patients were divided into an early feeding group (≤1 day, n = 3324) and a delayed feeding group (2-3 days, n = 2586). Clinical outcomes were compared between the groups by propensity matching analysis of 1508 pairs. RESULTS: There was no significant difference between the early and delayed feeding groups in the rebleeding rate within 7 days after colonoscopy (9.4% vs. 8.0%; p = 0.196) or in the rebleeding rate within 30 days (11.4% vs. 11.5%; p = 0.909). There was also no significant between-group difference in the need for interventional radiology or surgery or in mortality. However, the median length of hospital stay after colonoscopy was significantly shorter in the early feeding group (5 vs. 7 days; p < 0.001). These results were unchanged when subgroups of presumptive and definitive colonic diverticular bleeding were compared. CONCLUSION: The findings of this nationwide study suggest that early feeding after haemostasis can shorten the hospital stay in patients with ALGIB without increasing the risk of rebleeding.

PURPOSE: Urinary retention (UR) is a frequent complication following laparoscopic colorectal surgery. The aim of the present study was to investigate the risk factors for acute UR after laparoscopic surgery for colorectal cancer in patients receiving epidural analgesia. METHODS: A retrospective study was conducted of 201 patients who underwent laparoscopic surgery for colorectal cancer among those receiving epidural analgesia. Univariate and multivariate analyses were performed to determine the clinicopathological factors associated with acute UR. Acute UR was defined as Clavien-Dindo classification grade ≥ 1. RESULTS: The overall incidence of acute UR was 17.9% (36/201). The univariate analysis showed that male gender (P = 0.043), a history of chronic heart failure (P = 0.009), an increased level of serum creatinine (P = 0.028), an increased intraoperative fluid volume (P = 0.016), and an early postoperative date of urinary catheter removal (P = 0.003) were both associated with acute UR. The multivariate logistic regression analysis revealed an increased intraoperative fluid volume (100-ml increments; odds ratio [OR]: 1.085, 95% confidence interval [CI]: 1.034-1.138, P < 0.001), history of chronic heart failure (OR: 6.843, 95% CI: 1.893-24.739, P = 0.003), and postoperative date of urinary catheter removal (OR: 0.550, 95% CI: 0.343-0.880, P = 0.013) were independent risk factors for acute UR. CONCLUSION: Our findings suggest that an increased intraoperative fluid volume, history of chronic heart failure, and early removal of the urinary catheter are risk factors of UR after laparoscopic surgery for colorectal cancer in patients receiving epidural analgesia. An assessment using these factors might be helpful for predicting acute UR.

PURPOSE: Urinary dysfunction (UD) is a frequent complication following rectal surgery. The aim of the present study was to investigate the risk factors for acute UD after laparoscopic low anterior resection (LALAR) for rectal cancer in patients receiving epidural analgesia. METHODS: A retrospective study was conducted on 131 patients who underwent LALAR among those receiving epidural analgesia in a single institution between October 2008 and December 2019. Univariate and multivariate analyses were performed to determine the clinicopathological factors associated with acute UD. RESULTS: The overall incidence of acute UD was 16.0% (21/131). Univariate analysis showed that older age (P = 0.016) and earlier urinary catheter removal (P = 0.036) were associated with acute UD. Multivariate logistic regression analysis revealed that older age (10-year increments; odds ratio (OR) 2.046, 95% confidence interval (CI) 1.171-3.543, P = 0.011), urinary catheter removal before epidural analgesia discontinuation (OR 6.393, 95% CI 1.540-26.534, P = 0.011), and a large tumor circumference rate (10% increments; OR 1.263, 95% CI 1.043-1.530, P = 0.017) were independent risk factors for acute UD. CONCLUSION: Our findings suggest that older age, early removal of urinal catheter before epidural analgesia discontinuation, and large tumor circumference rate are risk factors of acute UD after LALAR for rectal cancer in patients receiving epidural analgesia.

PURPOSE: Early post-operative delirium (EPOD) is a frequent complication following colorectal surgery. The present study investigated the risk factors for EPOD after laparoscopic colorectal surgery in elderly patients. METHODS: A retrospective study was conducted among 208 patients ≥70 years old who underwent laparoscopic colorectal surgery. Univariate and multivariate analyses were performed to determine the clinicopathological factors associated with the EPOD. RESULTS: The overall incidence of EPOD was 10.1% (21/208). The univariate analysis showed that an older age (≥80 years old; P=0.002), sleeping pill medication before surgery (P=0.037), a history of dementia (P=0.030) and cerebrovascular disease (P=0.017), elevated levels of D-dimer (P=0.016), maximum intraoperative temperature ≥37 °C (P=0.036), and non-continuous usage of droperidol with analgesia (P=0.005) were associated with EPOD. The multivariate logistic regression analysis revealed an older age (≥80 years old; odds ratio [OR]: 6.26, 95% confidence interval [CI]: 1.94-20.15, P=0.002), sleeping pill medication before surgery (OR: 5.39, 95% CI: 1.36-21.28, P=0.016), history of cerebrovascular disease (OR: 3.91, 95% CI: 1.12-13.66, P=0.033), and maximum intraoperative temperature ≥37 °C (OR: 5.10, 95% CI: 1.53-16.92, P=0.008) to be independent risk factors. When the patients were divided into groups according to the number of positive risk factors, the prevalence rate was 6.5%, 16.0%, and 63.6% for patients with 1, 2, and 3 positive risk factors, respectively. CONCLUSION: Our findings suggest that an older age, sleeping pill medication before surgery, history of cerebrovascular disease, and maximum intraoperative temperature ≥37 °C are independent risk factors of EPOD after laparoscopic colorectal surgery in elderly patients.

PURPOSE: Refracture of pediatric both-bone diaphyseal forearm fractures (PBDFFs) may occur, even if the fractures are treated with intramedullary nailing. The purpose of this study was to investigate the risk of refracture of PBDFFs treated with intramedullary Kirschner wires (K-wires), which are commonly used in our clinic. METHODS: The present multicenter retrospective study included 60 consecutive patients with 60 PBDFFs who were treated with intramedullary K-wires at 5 hospitals between 2007 and 2016. The age of the patients at the time of the primary fracture ranged from 2 to 15 years. The characteristics of the primary fractures and treatment course were evaluated. RESULTS: Refracture occurred in 6 patients (10.0%). Three of the patients were young girls; the other 3 were adolescent boys. Refractures were caused by falling or during sports activity. The duration from primary fracture to refracture ranged from 46 to 277 days, and in 5 of the 6 patients refractures occurred within 6 months. Although we were unable to identify factors significantly contributing to refracture (e.g. fracture type or treatment procedures), radiographs at the latest visit before refracture demonstrated findings of immature healing in five of six patients. Both K-wires and external immobilization had been removed before complete fracture healing in a large proportion of patients with refracture (80.0%). CONCLUSIONS: Refracture of PBDFF may occur several months after treatment with intramedullary K-wires if the primary fracture shows immature healing. Physicians should pay special attention when judging radiographic fracture healing, even when the fracture is deemed to have clinically healed.

OBJECTIVE: To assess the correlations between dual-phase fluorine-18 fluorodeoxyglucose (18F-FDG) uptake and clinicopathological and immunohistochemical prognostic factors in patients with surgically resected breast cancer. SUBJECTS AND METHODS: We retrospectively analyzed the cases of 105 patients. We calculated the maximum standardized uptake value (SUVmax) at 85min (SUV1), SUVmax at 125min (SUV2) and the retention index [RI]. Spearman's rank correlation test, the Kruskal-Wallis test and receiver operating characteristic (ROC) analysis were performed to assess the association between 18F-FDG uptake and the clinicopathological and immunohistochemical factors: glucose transporter-1 (Glut-1), estrogen receptor alpha (ERα), ERß, progesterone receptor (PR), human epidermal growth factor 2 (Her2), mammalian target of rapamycin (mTOR), and P70S6kinase (P70S6). RESULTS: The SUV1 and SUV2 values were correlated with Glut-1, pathological tumor size, ERα negativity, and pathological stage (all P values were <0.05), but not with mTOR, P70S6, ERß, PR, Her2 or other factors. The SUV1 and SUV2 in the triple negative subtype were significantly higher than those of the hormone receptor-positive subtype (P<0.05). The RI was associated with pathological tumor size alone. In the ROC analysis of Glut-1, the areas under the curve for SUV1 and SUV2 were significantly larger than that for RI (SUV1, P=0.032, SUV2, P=0.022). CONCLUSION: Glucose transporter-1, estrogen receptor alpha negativity and nuclear grade might affect the high 18F-FDG uptake in breast cancer. The SUVmax might be more useful than the RI for predicting the Glut-1 expression and the aggressiveness of breast cancer.

This retrospective cohort study explored the prevalence of substantial weight loss (≥10% per year) in independent older individuals in order to develop and validate a scoring system for high-risk group identification and targeted intervention against malnutrition. We used insurance claims and the Kokuho Database (KDB), a nationwide repository of Japanese-specific health checkups and health assessments for the older people. The study included 12,882 community-dwelling individuals aged 75 years and older who were self-supported in their activities of daily living in Saga Prefecture, Japan. Health evaluations and questionnaires categorized weight-loss factors into organic, physiological, psychological, and non-medical domains. The resulting scoring system (SAGA score), incorporating logistic regression models, predicted ≥ 10% annual weight-loss risk. The results revealed a 1.7% rate of annual substantial weight loss, with the SAGA score effectively stratifying the participants into low-, intermediate-, and high-risk categories. The high-risk category exhibited a weight-loss rate of 17.6%, highlighting the utility of this scoring system for targeted prevention. In conclusion, the validated SAGA score is a crucial tool for identifying individuals at high risk of significant weight loss, enabling tailored interventions and social support benefiting both older individuals and their relatives.

PURPOSE: To explore the clinical features of COVID-19-associated conjunctivitis with the objective of preventing the spread of infection. STUDY DESIGN: Retrospective cohort study. METHODS: From March 2020 to March 2021, we retrospectively reviewed 26 (9.8%) consecutive COVID-19 patients with conjunctivitis among 282 COVID-19 cases admitted to our hospital. Clinical symptoms, onset date of conjunctivitis, time to patient recovery, and eye drop intervention were investigated. In addition, risk factors for developing conjunctivitis were statistically examined among 206 inpatients available for within 5 days of the onset. A multivariate analysis of conjunctivitis risk factors was performed. RESULTS: Among the 282 COVID-19 patients, 4 (1.4%) had conjunctival hyperemia as the primary symptom. The median time of onset was 4 days after the COVID-19 onset. Hyperemia was observed in all cases, but other ocular symptoms were rare. The median duration of hyperemia was 3 days. A multiple logistic regression analysis revealed that a young age (p=0.005) and current smoking habit (p=0.027) were independent risk factors for conjunctivitis after COVID-19. CONCLUSIONS: COVID-19-associated conjunctivitis is rare in the elderly and strongly associated with a history of smoking. It often occurs in the early stages of infection, and while hyperemia is recognized as a clinical symptom, other ocular symptoms are rare or non-existent. Many cases recover within a short time.

The study aimed to identify prognostic factors for patients with acute lower gastrointestinal bleeding and to develop a high-accuracy prediction tool. The analysis included 8254 cases of acute hematochezia patients who were admitted urgently based on the judgment of emergency physicians or gastroenterology consultants (from the CODE BLUE J-study). Patients were randomly assigned to a derivation cohort and a validation cohort in a 2:1 ratio using a random number table. Assuming that factors present at the time of admission are involved in mortality within 30 days of admission, and adding management factors during hospitalization to the factors at the time of admission for mortality within 1 year, prognostic factors were established. Multivariate analysis was conducted, and scores were assigned to each factor using regression coefficients, summing these to measure the score. The newly created score (CACHEXIA score) became a tool capable of measuring both mortality within 30 days (ROC-AUC 0.93) and within 1 year (C-index, 0.88). The 1-year mortality rates for patients classified as low, medium, and high risk by the CACHEXIA score were 1.0%, 13.4%, and 54.3% respectively (all P < 0.001). After discharge, patients identified as high risk using our unique predictive score require ongoing observation.

The relationship between blood group and rebleeding in acute lower gastrointestinal bleeding (ALGIB) remains unclear. This study aimed to investigate the association between blood group O and clinical outcomes in patients with ALGIB. The study included 2336 patients with ALGIB whose bleeding source was identified during initial endoscopy (from the CODE BLUE-J Study). The assessed outcomes encompassed rebleeding and other clinical parameters. The rebleeding rates within 30 days in patients with blood group O and those without blood group O were 17.9% and 14.9%, respectively. Similarly, the rates within 1 year were 21.9% for patients with blood group O and 18.2% for those without blood group O. In a multivariate analysis using age, sex, vital signs at presentation, blood test findings, comorbidities, antithrombotic medication, active bleeding, and type of endoscopic treatment as covariates, patients with blood group O exhibited significantly higher risks for rebleeding within 30 days (odds ratio [OR] 1.31; 95% confidence interval [CI] 1.04-1.65; P = 0.024) and 1 year (OR 1.29; 95% CI 1.04-1.61; P = 0.020) compared to those without blood group O. However, the thrombosis and mortality rates did not differ significantly between blood group O and non-O patients. In patients with ALGIB, blood group O has been identified as an independent risk factor for both short- and long-term rebleeding.

PURPOSE: The present study aimed to investigate the clinical implications of apical lymph node metastasis (ALNM) after curative resection of stage III colorectal cancer. METHODS: A retrospective study was conducted of 1403 consecutive colorectal cancer patients who underwent surgical resection at a single institution between April 2008 and January 2020. The characteristics of ALNM, the recurrence status and the relapse-free survival (RFS) were examined. RESULTS: The numbers of patients with stage ≤ I, II, III, and IV disease were 350, 437, 476, and 140 patients, respectively. Among these patients with stage III disease, ALNM was seen in 21 patients (4.4% of stage III patients). Among them, curative resection was performed in 19 patients. Recurrence was observed in 68% (13/19) of the patients with ALNM who received curative resection. The first sites of recurrence included the lymph nodes 53.8% (7/13), liver 30.8% (4/13), lung 15.4% (2/13), brain 7.7% (1/13), bone 7.7% (1/13), and peritoneum 7.7% (1/13). There was no significant difference in the RFS of patients with ALNM who were managed with or without adjuvant chemotherapy (P = 0.207). Furthermore, the RFS of the group managed without adjuvant chemotherapy and the group that received adjuvant chemotherapy with/without oxaliplatin did not differ to a statistically significant extent (P = 0.318). In stage III colorectal cancer patients with ALNM, recurrence was observed significantly more frequently in comparison to stage III colorectal cancer patients without ALNM (P = 0.007). The first site of recurrence in patients with ALNM was most frequently seen in the distant lymph nodes (P = 0.004). CONCLUSION: Our findings suggest that ALNM is strongly associated with recurrence in the distant lymph nodes and that it may lead to the development of systemic disease. The current regimen for stage III colorectal cancer may therefore not be sufficient for patients with stage III ALNM.

A prospective pilot study was conducted on 11 patients with rectal cancer to investigate fecal calprotectin (FC) as a diagnostic tool for detecting anastomotic leakage (AL) after low anterior resection. Among the 11 patients, 1 patient (9.1%) experienced AL (Clavien-Dindo Grade IIIa). During the post-operative course until post-operative day (POD) 5, the white blood cell count of the patient with AL was within the normal range. The C-reactive protein level in the AL and non-AL groups showed a similar time course. On the other hand, the FC level in patient with AL dramatically increased on POD5, while the FC level of the non-AL group remained relatively stable. There was no significant correlation between the preoperative FC level and the tumor circumference rate, tumor size, depth of invasion or stage. This pilot study showed the possibility of FC as a useful diagnostic tool for the detection of AL after low anterior resection for rectal cancer.
RESUMEN
BACKGROUND/AIM: Detection of pancreatic cancer using small samples of the pancreas obtained by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) remains a challenge. The purpose of this study was to investigate whether the detection of KRAS mutations in cell-free DNA (cfDNA) extracted from supernatants of liquid-based fixed cytology (LBC) specimens obtained using EUS-FNA in solid pancreatic cancer can be an auxiliary test for differential diagnosis. The purpose of this study was to investigate whether the detection of KRAS mutations in cell-free DNA (cfDNA) extracted from supernatants of liquid-based fixed cytology (LBC) specimens obtained using EUS-FNA in solid pancreatic cancer can be an auxiliary test for differential diagnosis. PATIENTS AND METHODS: This was a single-institution cohort study that included 50 patients with pancreatic lesions. cfDNA was isolated from the supernatant of fixed LBC samples, and KRAS mutation status was compared between cfDNA samples and FFPE small fragment tissues. RESULTS: Of the 50 cfDNA samples, 84% (42/50) were valid. KRAS mutations were detected in 57.1% (24/42) of the 42 valid samples. The sensitivity, specificity, and accuracy of KRAS mutation detection using cfDNA samples in the pancreatic lesions were 63.2% (24/38), 100.0% (4/4), and 66.7% (28/42), respectively. KRAS mutation status between FFPE small tissues and cfDNA samples were comparable. CONCLUSION: Gene mutation analysis using cfDNA from the supernatant of fixed LBC samples is an effective ancillary diagnostic tool for pancreatic cancer.

BACKGROUND/PURPOSE: We evaluated the difficulty score of laparoscopic cholecystectomy (LC) for acute cholecystitis (AC) proposed in the Tokyo guidelines 2018 (TG18) and analyzed the most appropriate scoring method. METHODS: We reviewed 127 patients who underwent LC for AC from January 2018 to March 2022. According to TG18, surgical difficulty was scored for five categories consisting of 25 intraoperative findings. The median, highest, and mean score of the five categories were analyzed for their association with surgical outcomes. RESULTS: The difficulty score distribution (0/1/2/3/4/5/6) was as follows: median (8/34/43/30/12/0/0), highest (1/1/32/42/36/15/0) and mean (19/49/49/10/0/0/0). In all three scoring methods, higher difficulty scores were significantly correlated with longer operative time, more blood loss, and higher occurrence of subtotal cholecystectomy in trend tests. The areas under the curve (AUCs) for prediction of prolonged operative time minutes and increased blood loss were similar in all three scoring methods. For conversion to subtotal cholecystectomy, the AUC was significantly better for the highest than median and mean score (p = .015 and p = .002, respectively). CONCLUSIONS: The difficulty score in TG18 appropriately reflects the surgical difficulty of LC for AC. The median, highest, and mean scores of the five categories are all available, and the highest scores are simple and versatile.

Intracholecystic papillary neoplasm (ICPN) is a non-invasive epithelial tumor that presents as a grossly identifiable mass arising in the mucosa and protruding into the lumen. ICPN is associated with invasive carcinoma. There are few studies on the clinicopathological features of ICPN, including that with invasive carcinoma. We evaluated the clinicopathological characteristics of 42 ICPNs and 41 conventional gallbladder adenocarcinomas (cGBAs). Subserosa or deeper (≥ss) invasion was significantly lower in ICPN (61.9%) than that in cGBA (90.2%) (P = 0.004). Cox regression analysis revealed that lymph node metastasis (hazard ratio [HR] [95% confidence interval (CI)]: 2.610 [1.131, 6.024], P = 0.025) and positive margin (HR [95% CI]: 5.143 [2.113, 12.516], P < 0.001), but not ≥ss invasion (HR [95% CI]: 1.541 [0.479, 4.959], P = 0.469), were independent prognostic factors. In addition, there was a significant interaction between histological type and lymph node metastasis (HR [95% CI]: 0.191 [0.042, 0.983], P = 0.033). In cGBA, the presence or absence of lymph node metastasis did not affect prognosis; however, ICPN without lymph node metastasis had better prognosis. Therefore, the histological classification of ICPN and cGBA and the pathological evaluation of lymph node metastasis in ICPN are crucial for determining prognosis.

AIMS: Relationship between baseline eGFR and the rate of decline in eGFR was investigated in diabetic kidney disease. MATERIALS AND METHODS: Patients with type 2 diabetes with microalbuminuria (MI) (n = 124) or macroalbuminuria (MA) (n = 81) received team-based medical care to prevent the development of diabetic kidney disease. The decline in eGFR over 4 years, divided into the first year and subsequent 3 years, was estimated by linear-mixed modeling. RESULTS: The eGFR showed a rapid decline during the first year, followed by a slower decline. On multiple regression analysis, the baseline eGFR was positively correlated with HbA1c in MI and negatively correlated with carotid plaque in MI and in MA. Subsequent eGFR decline following 1-year intervention was negatively correlated with the baseline eGFR and HbA1c level at 1 year in MI, whereas it was positively correlated with baseline eGFR and negatively correlated with the amount of proteinuria at 1 year in MA. Even in maintained baseline eGFR(⧠60 ml/min/1.73 m2) at the first year, when HbA1c ⧠7.5%, eGFR reduction rate and years to ESKD were much faster and shorter, compared to the group of HbA1c < 7.5% [- 3.44 (SE 1.137) vs. - 1.695 (SE 0.431) ml/min/1.73 m2/year, and 19.4 vs. 35.7 years, respectively]. In MA, lower eGFR (< 60 ml/min/1.73 m2) and higher proteinuria (⧠2.25 g/gCre) had a much faster eGFR decline and shorter time to ESKD, compared to the group of maintained eGFR and lower proteinuria (< 2.25 g/gCre) [- 5.240 (SE 1.537) vs. - 2.67 (SE 0.997) ml/min/1.73 m2/year, and 4.41 vs. 22.8 years, respectively]. CONCLUSIONS: In MI, even in maintained eGFR, the continued increase in eGFR in response to hyperglycemia (HbA1c ⧠7.5%) led to a faster decline in renal function and in MA, lower eGFR, with an increase in proteinuria, contributed to rapid decline of renal function.
