The clinical data of maintenance hemodialysis (MHD) patients from twenty hemodialysis centers in Guizhou province from June to September 2020 were collected by cross-sectional study. The patients were divided into AFD group and non-AFD group according to whether AFD had occurred. LTI was measured by body composition monitor. The results showed that the incidence of AFD in 2 781 MHD patients was 30.0% (835/2 781). Median LTI level was 15.2 (13.2, 17.5) kg/m². The LTI level in the AFD group was higher than that in the non-AFD group (P < 0.05). According to the tertiles of LTI, low LTI group (LTI ≤ 13.9 kg/m²) had the highest incidence of AFD (35.5%, 334/940), and the high LTI group had the lowest incidence of AFD (26.3%, 241/916), and the difference among the three groups was statistically significant (χ²=20.182,P < 0.001). Multivariate logistic regression analysis showed that low LTI group as the reference, the risk of AFD in moderate LTI group (13.9 kg/m² < LTI ≤ 16.6 kg/m²) and high LTI group were associated with the 20.0% (OR=0.800, 95% CI 0.650-0.986, P=0.036) and 22.8% (OR=0.772, 95% CI 0.616-0.966, P=0.024) decrease, respectively. These results suggest that low LTI level is independently associated with an increased risk of AFD in MHD patients.

The therapeutic technique of hemodialysis and the concept of clearance have both followed a long but instructive course of development. In addition, it recently has been shown that physiological changes occurring during hemodialysis have important clinical consequences both in the treatment of drug toxicity and in the selection of appropriate replacement doses of therapeutic drugs. Two major approaches for calculating hemodialysis clearance are currently used. The first approach, termed the recovery method is the “gold standard” that is recommended for use in the current US FDA draft guidance on the conduct of pharmacokinetic studies in patients with impaired renal function. The second approach, termed the A-V difference method, is used more commonly. Unfortunately, this method results in erroneous plasma clearance estimates when improper values for dialyzer flow are chosen. This constitutes a major pitfall that should be avoided in future studies.

Intraocular pressure was determined in 20 dialysis patients before, during and after dialysis. We examined the blood pressure, body weight and visual acuity before and after treatment. After dialysis, there was no statistically significant difference in blood pressure and body weight. No blurring of vision was noted. But a significant increase was noted in the intraocular pressure during dialysis. It is not yet clear what was the cause of intraocular pressure rise during dialysis. This. study suggests that all patients should undergo an ophthalmologic examination prior to dialysis. (Author)

PURPOSE: Due to their comorbidities, dialysis patients have many chances to undergo radiologic procedures using iodinated contrast media. We aimed to assess time-sequenced blood oxidative stress level after contrast exposure in hemodialysis (HD) patients compared to those in the non-dialysis population. MATERIALS AND METHODS: We included 21 anuric HD patients [HD-coronary angiography (CAG) group] and 23 persons with normal renal function (nonHD-CAG group) scheduled for CAG, and assessed 4 oxidative stress markers [advanced oxidation protein products (AOPP); catalase; 8-hydroxydeoxyguanosine; and malondialdehyde] before and after CAG, and subsequently up to 28 days. RESULTS: In the nonHD-CAG group, only AOPP increased immediately after CAG and returned to baseline within one day. However, in the HD-CAG group, all four oxidative stress markers were significantly increased starting one day after CAG, and remained elevated longer than those in the nonHD-CAG group. Especially, AOPP level remained elevated for a month after contrast exposure. CONCLUSION: Our study showed that iodinated contrast media induces severe and prolonged oxidative stress in HD patients.

OBJECTIVES: Safe and effective anticoagulation is essential for hemodialysis patients who are at high risk of bleeding. The purpose of this trial is to evaluate the effectiveness and safety of two-stage regional citrate anticoagulation (RCA) combined with sequential anticoagulation and standard calcium-containing dialysate in intermittent hemodialysis (IHD) treatment. METHODS: Patients at high risk of bleeding who underwent IHD from September 2019 to May 2021 were prospectively enrolled in 13 blood purification centers of nephrology departments, and were randomly divided into RCA group and saline flushing group. In the RCA group, 0.04 g/mL sodium citrate was infused from the start of the dialysis line during blood draining and at the venous expansion chamber. The sodium citrate was stopped after 3 h of dialysis, which was changed to sequential dialysis without anticoagulant. The hazard ratios for coagulation were according to baseline. RESULTS: A total of 159 patients and 208 sessions were enrolled, including RCA group (80 patients, 110 sessions) and saline flushing group (79 patients, 98 sessions). The incidence of severe coagulation events of extracorporeal circulation in the RCA group was significantly lower than that in the saline flushing group (3.64% vs. 20.41%, P<0.001). The survival time of the filter pipeline in the RCA group was significantly longer than that in the saline flushing group ((238.34±9.33) min vs. (221.73±34.10) min, P<0.001). The urea clearance index (Kt/V) in the RCA group was similar to that in the saline flushing group with no statistically significant difference (1.12±0.34 vs. 1.08±0.34, P=0.41). CONCLUSIONS Compared with saline flushing, the two-stage RCA combined with a sequential anticoagulation strategy significantly reduced extracorporeal circulation clotting events and prolonged the dialysis time without serious adverse events.

Drugs are well known causes of eosinophilic lung disease. In many patients, drug-induced eosinophilic lung disease presents with transient eosinophilic infiltrates that disappear after discontinuation of the drug. Some patients, however, experience a fulminant, acute eosinophilia-like disease. Recently, we experienced a case of amitriptyline-associated acute eosinophilic pneumonia with respiratory failure in a diabetic hemodialysis patient. Eight days after treatment with amitriptyline, sudden fever, chill, dry cough and dyspnea developed. Subsequently, multiple patch consolidations appeared on the chest radiographs. Bronchoalveolar lavage (BAL), established a diagnosis of acute eosinophilic pneumonia. After immediate discontinuation of amitriptyline, a rapid clinical and radiological improvement was observed. The present case indicates that the possibility of acute eosinophilic pneumonia should be fully considered in dialysis patients developing unexplained respiratory symptoms while on amitriptyline therapy.

OBJECTIVETo explore the clinical efficacy and safety of the early use of urokinase in the prevention and treatment on tunneled hemodialysis catheter related fibrin sheaths.

METHODSThirty-eight hemodialysis patients with tunneled central venous catheter and good catheter function were randomly divided into experimental group and control group. Urokinase was given after 3 days of indwelling catheter in the experimental group and after the onset of catheter dysfunction in the control group. The catheter function, mean blood flow and venous pressure of dialysis, coagulation, and side effects in the two groups were observed for 6 months.

RESULTSThe rates of catheter dysfunction on the arterial side were 0.65% and 2.71% in the experimental group and control group, respectively (P<0.05), with catheter dysfunction rates on the vein side of 0.92% and 2.41%, respectively (P<0.05). Catheter dysfunction occurred for the first time at 87.9 ± 24.1 days in the experimental group, and at 31.3 ± 11.5 days in the control group (P<0.05). The mean blood flow showed no significant difference between the two groups at 1 month after tube insertion (P>0.05), but was higher in the experimental group at 3 and 6 months after the tube insertion (P<0.05). The mean venous pressure in two groups was similar 1 and 3 months after tube insertion (P>0.05), but was significantly lower in the experimental group at 6 months (P<0.05). Compared with control group, the experimental group showed significantly prolonged prothrombin time (P<0.05) but similar rest coagulation parameters. No serious drug-related side effects occurred in these two groups.

CONCLUSIONEarly use of urokinase is safe and effective for prevention and treatment of tunneled hemodialysis catheter-related fibrin sheaths with minimal side effects.
