Association between subtypes of metabolic syndrome and prognosis in patients with stage I endometrioid adenocarcinoma: A retrospective cohort study.

Purpose: To investigate the association between subtypes of metabolic syndrome (MetS) and prognosis of patients with stage I endometrioid adenocarcinoma. Patients and methods: Patients with stage I endometrioid adenocarcinoma who received surgical treatment as primary therapy at the Department of Gynecology of the Sun Yat-sen Memorial Hospital between June 2015 and December 2019 were retrospectively enrolled. According to the diagnosis criteria of MetS, the patients were categorized as patients without MetS, patients with MetS but without raised fasting plasma glucose (FPG, including previously diagnosed diabetes), and patients with MetS and raised FPG. All the included patients were followed from the dates of surgery until death, June 2021, or loss to follow-up, whichever came first, and cancer recurrence (including metastasis) was studied as the main outcome. Cox regression was used to evaluate the associations between subtypes of MetS and the study outcome adjusting for potential confounding factors. Results: Among the included 387 patients with stage I endometrioid adenocarcinoma, 193 (49.9%) were without MetS, 65 (16.8%) were with FPG not involving MetS, and 129 (33.3%) were with raised FPG involved MetS. With a median follow-up of 1,253 days, the cumulative incidence of cancer recurrence was 8.76% (95% confidence interval (CI) 2.5%-14.62%), 28.31% (95% CI 2.33%-47.38%), and 7.54% (95% CI 1.54%-13.17%), respectively. After adjusting for age, menopause, histological grade, tumor size, lymph-vascular space invasion, deep myometrial invasion, and treatments, comorbid FPG not involving MetS is a stronger risk factor of cancer recurrence than comorbid raised FPG involving MetS (hazard ratio 2.82 (95% CI 1.10-7.24) versus 1.18 (95% CI 0.45-3.13)) when compared to patients without MetS. Conclusion: Comorbid MetS generally presents as a risk factor of poor prognosis in patients with stage I endometrioid adenocarcinoma after surgical treatment, but the magnitude of the association may vary between subtypes, in which FPG not involving MetS appears to be predominant.

The Correlation between Serum Lipoprotein(a) and Risk of Mortality in Patients on Peritoneal Dialysis.

BACKGROUND: Patients with peritoneal dialysis commonly have severe disorders of lipid metabolism, with particularly severe changes in serum lipoprotein(α) [Lp(α)]. Serum Lp(α) may play a role in the risk of mortality in peritoneal dialysis patients. The aim was to investigate the correlation between high serum Lp(α) levels and all-cause mortality and death from cardiovascular events and infection in peritoneal dialysis patients. METHODS: Three hundred and ninety-two patients with end-stage kidney disease who started peritoneal dialysis treatment between March 1, 2007 and May 31, 2020, were selected. Clinical data of all enrolled patients after 3 months of peritoneal dialysis were collected. Based on the median value of serum Lp(α) level, all enrolled patients were divided equally into a high serum Lp(α) level group (> 275.95 mg/L, n = 196) and a low serum Lp(α) level group (< 275.95 mg/L, n = 196). SPSS25.0 statistical software was used to analyze the factors affecting serum Lp(α) levels and the correlation between high serum Lp(α) levels and all-cause mortality and death from cardiovascular events and infection in peritoneal dialysis patients. RESULTS: Binary multivariate logistic regression analysis showed that higher low-density lipoprotein (LDL) levels (OR = 1.614, 95% CI: 1.261 - 2.068, p = 0.000) and high Body Mass Index (BMI) levels (OR = 1.063, 95% CI: 1.004 - 1.126, p = 0.036) were the risk factors for the high serum Lp(α) levels. High serum albumin levels (OR = 0.959, 95% CI: 0.927 - 0.991, p = 0.014) and high parathyroid hormone levels (OR = 0.999, 95% CI: 0.997 - 1.000, p = 0.010) were protective factors for the high serum Lp(α) levels. The cumulative survival of patients in the high serum Lp(α) level group was lower in death from cardiovascular events as shown by Kaplan-Meier survival analysis (Log-rank test χ2 = 4.348, p = 0.037). Multivariate Cox regression analysis showed that high serum Lp(α) levels were an independent risk factor for death from cardiovascular events in peritoneal dialysis patients (HR = 1.002, 95% CI: 1.001 - 1.003, p = 0.001). CONCLUSIONS: The occurrence of high serum Lp(α) levels in peritoneal dialysis patients was positively associated with LDL and BMI, and negatively associated with serum albumin and parathyroid hormone levels. High serum Lp(α) levels were related to the risk of death from cardiovascular events in peritoneal dialysis patients.

Successful application of roxadustat in the treatment of patients with anti-erythropoietin antibody-mediated renal anaemia: a case report and literature review.

Recombinant human erythropoietin (rHuEPO) has been used worldwide for treatment of renal anaemia due to its good curative effect. However, rHuEPO treatment is associated with a rare but severe complication because of the development of anti-EPO antibodies, which are difficult to treat. Currently, the main treatments for the anti-EPO antibodies include withdrawing the rHuEPO, providing blood transfusions and administrating steroid-based immunosuppressive agents. Although the above methods can alleviate anti-EPO-related anaemia, there are obvious side-effects such as decreased immunity and an increased risk of infection. Therefore, accurately identifying anti-EPO-related anaemia and effectively treating this complication is worth exploring. This current case report describes a 49-year-old female patient with chronic kidney disease that received rHuEPO subcutaneously and then developed anti-EPO antibody-mediated renal anaemia with her haemoglobin levels dropping to 37 g/l. The patient refused to be treated with steroids, so she received 120 mg roxadustat administered orally every 72 h and her Hb level increased to 110 g/l over a few months. This current case report demonstrates that roxadustat can be used to successfully treat anti-EPO antibody-mediated renal anaemia without the use of steroid-based immunosuppressants.
