BACKGROUND: Takayasu arteritis-induced renal arteritis (TARA), commonly seen in Takayasu arteritis (TA), has become one of the main causes of poor prognosis and early mortality in patients with TA. TARA progressing into Takayasu arteritis-induced renal artery stenosis (TARAS), could lead to severe complications including malignant hypertension, cardiac-cerebral vascular disease, and ischemic nephropathy. Since there existed no guidelines on treatments, this study aimed to review the comprehensive treatments for TARA. METHODS: We searched systematically in databases including PubMed, Ovid-Medline, EMBASE, Web of Science, China National Knowledge Infrastructure, Wanfang, and SinoMed, from inception to May 2018. Literature selection, data extraction, and statistical analysis were performed. RESULTS: Eighty-two literatures were recruited focusing on medical treatments (n = 34) and surgical treatments (n = 48). We found that combined medical treatments of glucocorticoids and conventional synthetic disease-modifying anti-rheumatic drugs could reach high rates of remission in patients with TARA, and biological disease-modifying anti-rheumatic drugs were preferred for refractory patients. After remission induction, surgical treatment could help reconstruct renal artery and recover renal function partly. Percutaneous transluminal angioplasty was the first choice for patients with TARAS, while open surgery showed a good long-term survival. CONCLUSIONS Patients with TARA should benefit both from medical treatments and from surgical treatments comprehensively and sequentially. Multidisciplinary team coordination is recommended especially in patients with severe complications.

In the past decade, mounting evidence points to the possibility of targeting bone for treating, preventing, and predicting type 2 diabetes mellitus. Osteoblast-derived osteocalcin (OCN) can stimulate insulin secretion, enhance insulin sensitivity, and favor glucose and fatty acid uptake and utilization. Lipocalin 2 is another osteokine secreted by osteoblasts and acts in appetite suppression. Neuropeptide Y may function in browning of white adipose tissue and energy expenditure. Osteocytes are proposed to have impact on the browning of white adipose tissue and energy expenditure through the secretion of bone morphogenetic protein 7 and sclerostin. Active bone resorption is also implicated in glucose homeostasis. In addition, there is evidence indicating the involvement of bone-derived receptor activator of nuclear factor κ-B ligand in the regulation of energy metabolism. We collect and summarize recent advances and the rationales for treating, preventing, and predicting diabetes by targeting skeleton. (Chin J Endocrinol Metab, 2018, 34: 543-548)

In order to standardize the application of imaging techniques in the clinical diagnosis and treatment of patients with Takayasu arteritis in China,the protocol for development of the guidelines for the imaging diagnosis and treatment of Takayasu arteritis was written by Zhongshan Hospital of Fudan University,the Rheumatology Committee of Chinese Medical Association,China Primary Health Care Foundation,and the Evidence-Based Medicine Center of Fudan University.The guideline working group will standardize the development of guidelines based on the existing imaging literature evidence of Takayasu arteritis and with reference to the WHO Guideline Development Manual.This protocol mainly introduced the significance of guideline formulation,the formation of working group,the selection of clinical problems,evidence retrieval and evaluation,the formation and publication of guidelines and other processes.

BACKGROUND: Rheumatoid arthritis (RA), a chronic systemic autoimmune disease, is characterized by synovitis and progressive damage to the bone and cartilage of the joints, leading to disability and reduced quality of life. This study was a randomized clinical trial comparing the outcomes between withdrawal and dose reduction of tofacitinib in patients with RA who achieved sustained disease control. METHODS: The study was designed as a multicenter, open-label, randomized controlled trial. Eligible patients who were taking tofacitinib (5 mg twice daily) and had achieved sustained RA remission or low disease activity (disease activity score in 28 joints [DAS28] ≤3.2) for at least 3 months were enrolled at six centers in Shanghai, China. Patients were randomly assigned (1:1:1) to one of three treatment groups: continuation of tofacitinib (5 mg twice daily); reduction in tofacitinib dose (5 mg daily); and withdrawal of tofacitinib. Efficacy and safety were assessed up to 6 months. RESULTS: Overall, 122 eligible patients were enrolled, with 41 in the continuation group, 42 in the dose-reduction group, and 39 in the withdrawal group. After 6 months, the percentage of patients with a DAS28-erythrocyte sedimentation rate (ESR) of <3.2 was significantly lower in the withdrawal group than that in the reduction and continuation groups (20.5%, 64.3%, and 95.1%, respectively; P  < 0.0001 for both comparisons). The average flare-free time was 5.8 months for the continuation group, 4.7 months for the dose reduction group, and 2.4 months for the withdrawal group. CONCLUSION: Withdrawal of tofacitinib in patients with RA with stable disease control resulted in a rapid and significant loss of efficacy, while standard or reduced doses of tofacitinib maintained a favorable state.

BACKGROUNDApproximately 15-20% cases of systemic lupus erythematosus (SLE) are diagnosed in children. There have been a few studies reporting the epidemiological data of pediatric-onset SLE (cSLE) in China, neither comparing the differences between cSLE and adult-onset SLE (aSLE). The aim of this study was to describe the impact of age of onset on clinical features and survival in cSLE patients in China based on the Chinese SLE Treatment and Research group (CSTAR) database.

METHODSWe made a prospective study of 225 cSLE patients (aged Results: The mean age of cSLE patients was 12.16 ± 2.92 years, with 187 (83.1%) females. Fever (P < 0.001) as well as mucocutaneous (P < 0.001) and renal (P = 0.006) disorders were found to be significantly more frequent in cSLE patients as initial symptoms, while muscle and joint lesions were significantly less common compared to aSLE subjects (P < 0.001). The cSLE patients were found to present more frequently with malar rash (P = 0.001; odds ratio [OR], 0.624; 95% confidence interval [CI], 0.470-0.829) but less frequently with arthritis (P < 0.001; OR, 2.013; 95% CI, 1.512-2.679) and serositis (P = 0.030; OR, 1.629; 95% CI, 1.053-2.520). There was no significant difference in SLE disease activity index scores between cSLE and aSLE groups (P = 0.478). Cox regression indicated that childhood onset was the risk factor for organ damage in lupus patients (hazard ratio 0.335 [0.170-0.658], P = 0.001). The survival curves between the cSLE and aSLE groups had no significant difference as determined by the log-rank test (0.557, P = 0.455).

CONCLUSIONScSLE in China has different clinical features and more inflammation than aSLE patients. Damage may be less in children and there is no difference in 5- year survival between cSLE and aSLE groups.

BACKGROUND: Plasminogen activator inhibitor-1 (PAI-1) plays an important role in the pathophysiology of sepsis, but the exact mechanism remains debatable. In this study, we investigated the associations among the serum levels of PAI-1, the incidence of 4G/5G promoter PAI-1 gene polymorphisms, immunological indicators, and clinical outcomes in septic patients. METHODS: A total of 181 patients aged 18-80 years with sepsis between November 2016 and August 2018 in the intensive care unit in the Xinhua Hospital were recruited in this retrospective study, with 28-day mortality as the primary outcome. The initial serum level of PAI-1 and the presence of rs1799768 single nucleotide polymorphisms (SNPs) were examined. Univariate logistic regression and multivariate analyses were performed to determine the factors associated with different genotypes of PAI-1, serum level of PAI-1, and 28-day mortality. RESULTS: The logistic analysis suggested that a high serum level of PAI-1 was associated with the rs1799768 SNP of PAI-1 (4G/4G and 4G/5G) (Odds ratio [OR]: 2.49; 95% confidence interval [CI]: 1.09, 5.68). Furthermore, a high serum level of PAI-1 strongly influenced 28-day mortality (OR 3.36; 95% CI 1.51, 7.49). The expression and activation of neutrophils (OR 0.96; 95% CI 0.93, 0.99), as well as the changes in the expression patterns of cytokines and chemokine-associated neutrophils (OR: 1.00; 95% CI: 1.00, 1.00), were both regulated by the genotype of PAI-1. CONCLUSIONS Genetic polymorphisms of PAI-1 can influence the serum levels of PAI-1, which might contribute to mortality by affecting neutrophil activity. Thus, patients with severe sepsis might clinically benefit from enhanced neutrophil clearance and the resolution of inflammation via the regulation of PAI-1 expression and activity.
