ABSTRACT
BACKGROUND: Existing evidence indicates that elevated triglycerides may affect blood pressure, but the underlying mechanisms are not fully understood. Herein, we aim to identify the intermediaries of associations of triglyceride with systolic blood pressure and diastolic blood pressure using the Mendelian randomization (MR) framework. METHODS: Triglyceride-associated single nucleotide polymorphisms were extracted and used to match phenotypes in PhenoScanner. From the broad spectrum of possible triglyceride-associated traits, potential mediators linking triglyceride to blood pressure were screened out by MR and MR-based mediation analysis. Moreover, cross-sectional observational data of 206 341 adults were used to validate the mediators identified at the genetic level. RESULTS: Among the nearly 100 raw phenotypes matched by 313 triglyceride-associated single nucleotide polymorphisms, 39 traits were filtered and integrated into subsequent analysis. By further filtering using MR analysis, only pulse rate and lymphocyte count (LC) were identified as independent mediators. MR-based mediation analysis showed that genetically predicted LC could mediate 9.2% of the association of triglyceride with systolic blood pressure; genetically predicted pulse rate and LC could mediate 18.3% and 17.6% of the association of triglyceride with DBP, respectively. Observational data also support the mediating role of pulse rate and LC. CONCLUSIONS: The current findings highlighted the mediating role of pulse rate and LC on the causal pathway from triglyceride to blood pressure and may contribute to a better understanding of the pathogenic mechanism by which high triglyceride affects other cardiometabolic factors.

BACKGROUND: Obesity is a well-known modified risk factor for isolated systolic hypertension (ISH), but evidence is lacking regarding whether the combination of anthropometric and lipid indicators could strengthen their correlation with ISH. Therefore, we compared the association of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), visceral adiposity index (VAI), lipid accumulation product index (LAP), and cardiometabolic index (CMI) with ISH. METHODS: A total of 106,248 adults who received routine health screening and did not have diastolic blood pressure ≥ 90 mmHg were recruited in this cross-sectional study. The associations between these indicators and ISH were evaluated using multivariate regression. RESULTS: Each standard deviation (SD) increase in traditional obesity indicators (especially WHR and WHtR) had significantly higher multivariate-adjusted odds ratios (ORs) than each SD increase in lipid-related obesity indicators. In addition, multivariate-adjusted ORs for ISH in the third (vs. the first) tertile of traditional obesity indicators were also significantly higher than those of lipid-related indicators. Moreover, traditional obesity indicators exhibited a higher area under the ROC curve for discriminating ISH than lipid-related obesity indicators. CONCLUSIONS: Traditional obesity indicators were more strongly associated with ISH than lipid-related obesity indicators among Chinese adults.

The vital role of insulin resistance (IR) in the pathogenesis of isolated systolic hypertension (ISH) has been expounded at the theoretical level. However, research on the correlation between some specific IR indicators and ISH is still rare, especially at different glycemic statuses. We conducted this study to explore the association between three IR indicators and ISH among young and middle-aged adults with normal fasting plasma glucose (NFG). This large cross-sectional study included 8246 young and middle-aged men with NFG and diastolic blood pressure < 90 mmHg. The homeostasis model assessment for IR (HOMA-IR) index, triglyceride glucose (TyG) index, and the metabolic score for IR (METS-IR) were calculated with the corresponding formula. The proportions of ISH among young and middle-aged men were 6.7% and 4.4%, respectively. After fully adjusting, only HOMA-IR rather than TyG and METS-IR was significantly associated with ISH. Moreover, fully adjusted smooth curve fitting showed that the association between HOMA-IR and ISH were approximately linear in both two age groups (P for non-linearity were 0.047 and 0.430 in young and middle-aged men, respectively). Among young and middle-aged men with NFG, using HOMA-IR instead of noninsulin-dependent IR indicators may have advantages in the hierarchical management of ISH. Further longitudinal research may be needed to determine their potential causal relationship.

INTRODUCTION: Apart from their recognized lipid-lowering effect, Hedan tablets, a mixture of Chinese herbal medicines, have demonstrated a certain weight-loss effect in clinical practice. The aim of this randomized, double-blind, placebo-controlled study was to verify the effect of Hedan tablets on body weight (BW) and insulin resistance (IR) in patients with metabolic syndrome (MetS). METHODS: A total of 62 eligible patients with MetS were divided into two groups: the treatment group (Hedan tablets at 4.38 g/day tid) and the control group (placebo treatment). Both groups attended follow-ups at 8, 16, and 24 weeks during the process. The parameters of the assessment include lipid level, BW, triglyceride (TG) to high-density lipoprotein cholesterol (HDLc) ratio (TG/HDLc), homeostasis model assessment for IR (HOMA-IR) index, and adiponectin. RESULTS: Patients in the treatment group showed a significant decrease in BW compared to those in the control group (-4.47 vs. 0.06 kg) after 8 weeks of treatment. A significant decrease in body mass index (BMI) was also observed in the treatment group after 16 weeks of treatment (-1.79 vs. -0.03 kg/m2). In the treatment group, 20 out of 31 (64.5%) patients lost 5-10% BW and 4 out of 31 (12.9%) patients lost over 10% BW after 24 weeks of treatment. Although there were no significant changes in the patients' HOMA-IR, the treatment group showed a significant reduction in TG/HDLc (-0.98 vs. -0.19) after 8 weeks of treatment and a significant increase in adiponectin (6.87 vs. -0.43) after 16 weeks of treatment. DISCUSSION/CONCLUSION: The Hedan tablets significantly improve BW, BMI, TG/HDLc, and adiponectin in patients with MetS. Thus, Hedan tablets may be used as an adjunct to existing MetS management methods.

BACKGROUND AND AIMS: Although hyperinsulinemia and insulin resistance (IR) together cause metabolic diseases, the available evidence fails to link hyperinsulinemia with blood pressure (BP) elevation. To further understand the role of hyperinsulinemia in the pathophysiology of hypertension, we conducted this study to investigate the moderating effect of fasting insulin (FINS) on the association between IR and BP. METHODS AND RESULTS: The health screening data of 72,076 individuals were analyzed for this moderation analysis. IR was indicated by the homeostatic model assessment of insulin resistance (HOMA-IR), triglyceride-glucose index (TyG), and triglyceride to high-density lipoprotein cholesterol ratio (TG/HDLc). In the adjusted model, three IR indicators were considered independent variables; FINS was used as a moderator, and systolic BP (SBP) and diastolic BP (DBP) were used as dependent variables. The regression coefficient of the interaction term between the three IR indicators and FINS was significantly negative in all moderation models. Simple slope tests and the Johnson-Neymann technique also indicated that FINS negatively moderated the association between IR and BP. CONCLUSIONS: This moderation analysis showed that FINS negatively mediated the association between IR and BP, suggesting that hyperinsulinemia may buffer, not reinforce, the effect of IR on hypertension.

BACKGROUND: Identification and intervention of insulin resistance may be beneficial to the prevention of hyperuricemia (HUA) and its related diseases. Thus, we conducted this longitudinal study to examine the relation of triglyceride-glucose index (TyG), a simple noninsulin-based IR assessment tool, and its derivatives with the risk of HUA. METHODS: A total of 42,387 adults who received routine health screening and were free of HUA were included for the longitudinal analyses. TyG, body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WtHR) were calculated through anthropometric and biochemical indicators. Associations of TyG, TyG-BMI, TyG-WC, and TyG-WHtR with HUA risk were estimated using Cox regression analyses. RESULTS: The incident cases of HUA occurred in 4,230 subjects during the 138,163 person-years of observation, and the crude incidence rate of HUA was 30.6 per 1000 person-years. After multivariate adjustment, we observed an increased risk for incident HUA for the upper TyG and its derivatives' tercile. The HRs of TyG were greater than that of its components in both sexes. Compared with TyG, TyG-related parameters only had higher HRs in women but not in men. CONCLUSIONS: TyG and its integration with obesity indicators have the potential to help risk stratification and prevention of HUA, especially among women.
ABSTRACT
For normal-weight population, the management of prehypertension may be more beneficial by identifying insulin resistance (IR) status than relying solely on traditional indicators of obesity. We investigated the association of triglyceride glucose (TyG) index, a simple surrogate marker of IR, and its combination of obesity indices with prehypertension in lean individuals. A total of 105 070 lean adults without hypertension were included in this analysis. Body mass index (BMI), waist circumference (WC), waist-to-height ratio (WtHR), and TyG were calculated according to the corresponding formula; TyG-BMI, TyG-WC, and TyG-WHtR were calculated by multiplying the corresponding two parameters. Gardner-Altman plots, partial correlation, and logistic regression analyses were applied to explore the associations in continuous variables and quartiles. The prehypertensive ones had higher mean values of TyG, TyG-BMI, TyG-WC, and TyG-WHtR than normotensive individuals. All the four indicators showed positive correlations with systolic blood pressure and diastolic blood pressure. After full adjustment, only TyG-BMI and TyG-WC were significantly associated with prehypertension in both genders. Furthermore, TyG-BMI had the highest OR for prehypertension. Our study showed that TyG-BMI might be an accessible and complementary monitor in the hierarchical management of non-obese prehypertensive patients.

BACKGROUND: Systemic inflammation may be involved in the formation and progression of thyroid nodule (TN). The aim of this large-scale study was to investigate the association of several simple inflammatory markers with the presence and size of TN. METHODS: A total of 133,698 adults were included for the current analysis. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and monocyte-to-high-density lipoprotein cholesterol ratio (MHR) were calculated. The logistic regression was used to explore the association of the four markers with the presence and size of TN. RESULTS: The prevalence of TN was 55.1% among females and 44% among males; 13% of women and 8% of men had non-micronodule. In women, MHR and PLR were significantly associated with the presence of TN and non-micronodule; in men, MHR and NLR were significantly associated with the presence of TN and non-micronodule. CONCLUSIONS: As a low-cost, simple, and reproducible inflammatory marker, MHR is strongly associated with the presence and size of TN irrespective of the gender.

Background: Nonobese individuals with disproportionate body fat distribution are also vulnerable to dysglycemia. This study aimed to evaluate the association between three visceral adiposity surrogates and impaired fasting glucose (IFG) in nonobese Chinese individuals. Methods: A total of 70,200 nonobese adults without diabetes were included in this analysis. Two diagnostic criteria (IFG-ADA and IFG-WHO) were used to define IFG. The values of the visceral adiposity index, lipid accumulation product index (LAP), and cardiometabolic index (CMI) were calculated. Multivariable logistic analysis was used to evaluate the association between these surrogates and IFG. Results: Among the three indicators, only LAP and CMI were positively correlated with fasting plasma glucose (all P < 0.001). After fully adjusting for confounders, only LAP and CMI exhibited significant associations with IFG. For women, the odds ratios (ORs) for IFG-ADA in the highest quartile of the LAP and CMI were 1.967 (95% confidence interval [CI]: 1.645-2.353) and 1.594 (95% CI: 1.383-1.836), respectively; and were 2.025 (95% CI: 1.597-2.567) and 2.017 (95% CI: 1.647-2.470), respectively, for IFG-WHO (all P < 0.001). For men, the ORs for IFG-ADA of the LAP and CMI were 1.503 (95% CI: 1.233-1.833) and 2.045 (95% CI: 1.752-2.388), respectively; and were 1.534 (95% CI: 1.174-2.005) and 2.541 (95% CI: 2.025-3.188), respectively, for IFG-WHO (all P < 0.001). Conclusions: The LAP and CMI, cost-effective and simple visceral adiposity surrogates, are strongly associated with IFG in nonobese Chinese individuals. These surrogates might be potential targets to monitor for the recognition and management of excess visceral adiposity in nonobese individuals with prediabetes.

BACKGROUND: A blood pressure (BP) of 130-139/80-89âmmHg has been defined as stage 1 hypertension by the 2017 American College of Cardiology/American Heart Association High Blood Pressure Clinical Practice Guidelines. This study was conducted to assess the association of cardiovascular risk factors (CRFs) and newly defined stage 1 hypertension in China. METHODS: We analyzed the data of 84,489 adults with a BP of <140/90 mmHg. The 10-year cardiovascular disease (CVD) risk score was calculated using the China-PAR equation. Logistic analysis was used to assess the association between CRFs and stage 1 hypertension. RESULTS: The mean values of CRFs, the proportion of metabolic abnormalities, the prevalence of ≥2 CRFs, and the 10-year CVD risk of individuals with a BP of 130-139/80-89 mmHg were significantly higher than those of the population with a BP of <130/80 mmHg. The adjusted odds ratios (ORs) of waist circumference, fasting plasma glucose (FPG), and triglycerides were 1.362 (CI 95% = 1.081-1.715, p = .009), 1.264 (CI 95% = 1.093-1.462, p = .002), and 1.331 (CI 95% = 1.009-1.755, p = .043), respectively. Other CRFs were not significantly associated with stage 1 hypertension. CONCLUSIONS: Multidisciplinary and targeted interventions are required to manage the CRFs (especially abdominal obesity, elevated FPG, and hypertriglyceridemia) of the population with a BP of 130-139/80-89 mmHg in China.

Most animal spinal cord injury models involve a laminectomy, such as the weight drop model or the transection model. However, in clinical practice, many patients undergo spinal cord injury while maintaining a relatively complete spinal canal. Thus, open spinal cord injury models often do not simulate real injuries, and few previous studies have investigated whether having a closed spinal canal after a primary spinal cord injury may influence secondary processes. Therefore, we aimed to assess the differences in neurological dysfunction and pathological changes between rat spinal cord injury models with closed and open spinal canals. Sprague-Dawley rats were randomly divided into three groups. In the sham group, the tunnel was expanded only, without inserting a screw into the spinal canal. In the spinal cord injury with open canal group, a screw was inserted into the spinal canal to cause spinal cord injury for 5 minutes, and then the screw was pulled out, leaving a hole in the vertebral plate. In the spinal cord injury with closed canal group, after inserting a screw into the spinal canal for 5 minutes, the screw was pulled out by approximately 1.5 mm and the flat end of the screw remained in the hole in the vertebral plate so that the spinal canal remained closed; this group was the modified model, which used a screw both to compress the spinal cord and to seal the spinal canal. At 7 days post-operation, the Basso-Beattie-Bresnahan scale was used to measure changes in neurological outcomes. Hematoxylin-eosin staining was used to assess histopathology. To evaluate the degree of local secondary hypoxia, immunohistochemical staining and western blot assays were applied to detect the expression of hypoxia-inducible factor 1α (HIF-1α) and vascular endothelial growth factor (VEGF). Compared with the spinal cord injury with open canal group, in the closed canal group the Basso-Beattie-Bresnahan scores were lower, cell morphology was more irregular, the percentage of morphologically normal neurons was lower, the percentages of HIF-1α- and VEGF-immunoreactive cells were higher, and HIF-1α and VEGF protein expression was also higher. In conclusion, we successfully established a rat spinal cord injury model with closed canal. This model could result in more serious neurological dysfunction and histopathological changes than in open canal models. All experimental procedures were approved by the Institutional Animal Care Committee of Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, China (approval No. HKDL201810) on January 30, 2018.
ABSTRACT
Insulin resistance (IR) plays a crucial role in the development of hypertension, so early recognition of IR is of substantial clinical importance for the management of hypertension. But traditional IR indexes are invasive, complex, and impractical. We aimed to evaluate the associations between three simple IR indexes and hypertension in different body mass index (BMI) categories. A total of 142 005 adults who did not take antihypertensive medication were included in this analysis. The ratio of triglycerides to high-density lipoprotein cholesterol (TG/HDLc), the product of fasting triglycerides and glucose (TyG), and metabolic score for IR (METS-IR) were calculated according to the corresponding formulas. The associations between them and hypertension were analyzed by logistic regression. Among the three indicators, only METS-IR had positive correlations with blood pressure levels (all P < 0.001). After full adjustment, METS-IR was significantly associated with hypertension in the normal BMI group but not in the elevated BMI group. The OR for hypertension in the normal BMI group in the highest quartile of METS-IR was 2.884 (95% CI: 2.468-3.369) in the total sample, 1.915 (95% CI: 1.614-2.271) in females and 2.083 (95% CI: 1.717-2.527) in males. Our findings indicate that METS-IR, a simple and cost-effective IR index, was strongly associated with hypertension in normal-weight Chinese subjects. It could help monitor and manage hypertension in normal-weight individuals.

OBJECTIVE: The association between hyperuricemia and insulin resistance (IR) has been demonstrated by many studies, but the traditional IR indexes are too impractical to be used in clinical practice for the recognition of the IR state in individuals with hyperuricemia. Therefore, we aimed to further investigate the association between hyperuricemia and three non-insulin-based IR indexes in this large-scale cross-sectional study. METHODS: A total of 174,695 adults without self-reported use of antihyperuricemic agents, hypoglycemic agents, or lipid-lowering drugs were included in the current analysis. The triglyceride to high-density lipoprotein cholesterol ratio (TG/HDLc), the product of fasting triglycerides and glucose (TyG), and metabolic score for IR (METS-IR) were calculated. Then, logistic regression analyses were applied to explore their association with hyperuricemia. RESULTS: The TG/HDLc, TyG, and METS-IR all had positive correlations with uric acid level. However, only TG/HDLc and TyG were significantly associated with hyperuricemia in both sexes and body mass index (BMI) classification (the ORs of the highest quartile for each were 6.751 and 1.505 in females and 6.487 and 1.646 in males, respectively). The AUC values of TG/HDLc and TyG to discriminate hyperuricemia were also statistically significant in both sexes and BMI classification (all greater than 0.7). CONCLUSIONS: TG/HDLc and TyG are strongly associated with hyperuricemia regardless of BMI classification. These two obtainable and cost-effective non-insulin-based IR indexes could be potential monitors during the management of hyperuricemia and prevention of its IR-driven comorbidities. Key Points ⢠In this large-scale study, we identified TG/HDLc and TyG as indicators for identification of IR in patients with hyperuricemia. ⢠These simple and practical IR indicators are of substantial clinical importance for implementing preventive strategies against IR-driven comorbidities of hyperuricemia.

Background: Insulin resistance (IR) is the common pathophysiology of prehypertension and prediabetes. Recognition of IR in one of the two disease states is critical for carrying out preventive strategies of another disease state. This study aimed to explore which simple IR indexes were significantly associated with prehypertension in subjects with normoglycemia. Methods: A total of 108,370 adults without elevated fasting plasma glucose and hypertension were included in this study. The three simple IR indexes [triglycerides to high-density lipoprotein cholesterol ratio, the product of fasting triglycerides and glucose, and metabolic score for IR (METS-IR)] were calculated. Partial correlation was used to analyze the correlation between the three indicators and blood pressure (BP) levels, and logistic regression analysis was used to explore their association with prehypertension. Results: Among the three indicators, only METS-IR had positive correlations with systolic and diastolic blood pressure levels. Furthermore, METS-IR was also significantly associated with prehypertension, irrespective of the categorization of waist circumference (WC). The odds ratios of the highest quartile were 2.223 (95% confidence interval [CI]: 2.044-2.417) in all subjects, 2.022 (95% CI: 1.501-2.725) in elevated WC subgroup, and 1.815 (95% CI: 1.620-2.034) in normal WC subgroup. Conclusions: METS-IR was associated with prehypertension in normoglycemic Chinese subjects, which bypasses the impact of WC and might be valuable for the management of prehypertension and the prevention of prediabetes in different ethnic groups.

OBJECTIVE: To assess the 10-year Atherosclerotic Cardiovascular Disease (ASCVD) risk score among adults in eastern China using the China-PAR equation which formulated primarily for the Chinese population. METHODS: Data from 72,129 individuals from 35-74 years old who received routine physical examinations in eastern China were analyzed in this study. The 10-year risk scores were calculated using the China-PAR equation. The chi-square test and logistic regression were then performed to evaluate the association between the selected risk factors and overall CVD risk. RESULTS: The mean 10-year ASCVD risk scores were 3.82% ± 3.76% in men and 1.30% ± 1.65% in women based on the China-PAR equation. Overall, 20% of men and 3.5% of women were intermediate-risk, and 7.3% of men and 0.3% of women were high-risk. Waist to hip ratio (WHR) [OR = 1.16 (CI 95% = 1.06-1.26)], waist to height ratio (WHtR) [OR = 1.16 (CI 95% = 1.05-1.28)], non-high-density lipoprotein cholesterol (non-HDL-C) [OR = 1.23 (CI 95% = 1.09-1.39)], and total cholesterol (TC)/HDL-C [OR = 1.68 (CI 95% = 1.46-1.94)] were more strongly associated with CVD risk than body-mass index (BMI), waist circumference (WC), and TC alone. CONCLUSION: Male-specific prevention and treatment strategies for ASCVD are needed in eastern China. In addition, WHR, WHtR, non-HDL-C, and TC/HDL-C which not included in the the China-PAR equation were also independently associated with 10-year ASCVD risk score categories.

BACKGROUND: The association between several novel adiposity indices and hyperuricemia is inconclusive. Therefore, we aimed to investigate this association so as to provide theoretical support for the management of hyperuricemia in overweight/obese individuals. METHODS: A cross-sectional study was carried out among 174,698 adults. The values of body adiposity index (BAI), conicity index (CI), a body shape index (ABSI), body roundness index (BRI), visceral adiposity index (VAI), lipid accumulation product (LAP) index, and cardiometabolic index (CMI) were divided into four quartiles, and multivariate logistic analysis was used to analyze the association between them and hyperuricemia. Receiver operating characteristic curve and area under curve (AUC) were used to evaluate the power of predictions for hyperuricemia. RESULTS: After adjusting for confounding variables, LAP and CMI exhibited stronger association with hyperuricemia than other indices. The odd ratio (OR) for hyperuricemia in the highest quartile of the LAP and CMI was 2.049 (CI 95% = 1.824-2.302) and 4.332(CI 95% = 3.938-4.765). The AUC value of LAP was 0.632 (95% CI = 0.626-0.637), p < 0.001; and the AUC value of CMI was 0.687 (95% CI = 0.682-0.692), p < 0.001. The optimal cutoff values of LAP and CMI were 26.21 and 0.485, respectively. CONCLUSIONS: LAP and CMI, combination of WC and lipid parameters and reliable visceral adiposity indices, were strongly associated with hyperuricemia than other indices. So they could be potential monitoring indicators for hyperuricemia management in overweight/obese individuals.

To estimate the mortality and describe the causes of death in a large multicenter cohort of hospitalized patients with SLE in China. This was a retrospective study of a nationwide SLE cohort (10 centers, 29,510 hospitalized patients) from 2005 to 2014 in China. Standardized mortality ratios (SMRs) were calculated for all death and were stratified by sex and age. Chi-square test was used to determine whether the major causes of death vary in age, sex, duration of SLE, disease activity, or medications. Comparison between dead patients and survival controls was used to identify the risk factors for mortality. Logistic regression analysis was used to evaluate the risk factors for mortality. A total of 360 patients died during the study period, accounting for 1.22%. The overall SMR was 2.13 (95% CI 1.96, 2.30), with a particularly high SMR seen in subgroups characterized by younger age. Infection (65.8%) was the most common cause of death, followed by lupus nephritis (48.6%), hematological abnormality (18.1%), neuropsychiatric lupus/NPSLE (15.8%), and interstitial pneumonia (13.1%). Cardiovascular disease and malignancy contributed little to the causes of death. Infection, in particular severe pulmonary infection, emerged as the foremost risk factor for mortality, followed by lupus encephalopathy. However, lupus nephritis and hematological abnormalities occurred more frequently in survival patients. SLE patients at a younger age of diagnosis have a poorer prognosis. Infection dominated the causes of death in recent China. Ethnicity and medications might account for the differences in causes of death compared with western populations.

The metabolic characteristics of rheumatoid arthritis (RA) or diabetes mellitus (DM) have been studied, but the metabolic abnormalities of RA patients complicated with DM are not completely understood. Therefore, we recruited RA patients with DM to investigate the metabolic abnormalities in these patients. We collected data of RA patients with DM and age- and sex-matched RA and DM patients from Changhai Hospital's electronic medical record system. Data of demographically matched healthy controls were also collected from the health management system of the Hangzhou Sanatorium of People's Liberation Army. Blood pressure, uric acid, glucose, and lipid levels were compared. The clinical data of RA with DM (n = 104), DM (n = 100), and RA (n = 100) patients and healthy controls (n = 100) were collected and compared. RA patients with DM had higher blood pressure and lower high-density lipoprotein cholesterol levels than the other three groups, a higher triglycerides (TG) level than healthy controls and RA patients, and a lower TG level than DM patients. RA patients with DM exhibited a relatively high proportion of metabolic abnormalities based on existing standards. Our study examined metabolic abnormalities in RA patients with DM for the first time, and our results suggest that clinicians should pay more attention to the metabolic abnormalities of RA patients with DM.
