When women during pregnancy and lactation are also complicated with certain diseases, and need to take glucocorticoids and immunosuppressive agents, the doctors should consider not only the efficacy of the drugs, but also the safety of the drugs to the mother, the fetus, and the infant to be fed.Which glucocorticoids and immunosuppressive agents can be safely used during pregnancy and lactation?Which drugs can pass through the placenta to affect the growth and development of the fetus, or to be teratogenic? Which drugs can be secreted into the milk through the breast, acting on newborns or infants?This article gave a more detailed introduction to all of the above topics.
Objective To investigate the clinical features of elderly patients with stage 3-4 chronic kidney disease (CKD) and to analyze the risk factors of the kidney function progression.Methods This was a cross-sectional study. The clinical data of elderly patients (≥60 years)with stable clinical manifestation in Beijing Hospital from January, 2014 to December, 2015 were collected. Based
BackgroundPersistent proteinuria is an important factor contributing to the progression of diabetic nephropathy. The present randomized double-blind placebo-controlled multicenter clinical study evaluated the efficacy and safety of telmisartan combined with the antioxidant probucol in reducing urinary protein levels in patients with type 2 diabetes (T2D).MethodsPatients with T2D and 24-h proteinuria 0.5-3 g were enrolled in the study and randomly assigned to one of two groups: a telmisartan or a probucol + telmisartan group. Both groups were given telmisartan 80 mg q.d. for 48 weeks. The probucol + telmisartan group was given probucol 500 mg b.i.d. for the first 24 weeks, with the dosage then reduced to 250 mg b.i.d. for the remaining 24 weeks. The telmisartan group was given probucol placebo.ResultsIn all, 160 patients were enrolled in the present study. The 24-h proteinuria levels were significantly reduced in the probucol + telmisartan compared with telmisartan group. For patients with baseline 24-h proteinuria levels <1.0 g, both treatments resulted in significant reductions in 24-h proteinuria levels after 48 weeks treatment. However, in patients with baseline 24-h proteinuria levels 1.0 g, 24-h proteinuria levels after 48 weeks treatment were only reduced in the probucol + telmisartan group. There was no significant difference between the two groups for either adverse cardiovascular or other events.ConclusionsIn patients with diabetic nephropathy, probucol combined with telmisartan more effectively reduces urinary protein levels than telmisartan alone.

BACKGROUND To identify the relationship between predialysis pulse wave velocity (PWV), postdialysis PWV during 1 hemodialysis (HD) session, and deaths in maintenance HD patients. METHODS 43 patients were recruited. PWV was measured before and after one HD session and dialysis- related data were recorded. Clinical data such as blood pressure, blood lipids, and blood glucose, were carefully observed and managed in a 5-year follow-up. The association between all-cause death, predialysis PWV, postdialysis PWV, change of PWV (ΔPWV), and other related variables were analyzed. RESULTS After 5 years, 17 patients (39.5%) died. Univariate Cox regression analysis showed that all-cause death of the patients significantly correlated with age, postdialysis PWV, and ΔPWV. Multivariate Cox regression analysis revealed that postdialysis PWV was an independent predictor for all-cause death in these patients (HR: 1.377, 95% CI: 1.146 - 1.656, p = 0.001). CONCLUSION Elevated postdialysis PWV significantly correlated with and was an independent predictor for all-cause death in maintenance HD patients.
Background:The efficacy and safety of telmisartan combined with clopidogrel, leflunomide, or both drugs for immunoglobulin A nephropathy (IgAN) are unclear. This study was designed to evaluate the efficacy and safety of telmisartan combined with clopidogrel, leflunomide, or both drugs for IgAN. Methods:It is a multicenter, prospective, double-dummy randomized controlled trial. Primary IgAN patients were recruited in 13 renal units across Beijing, China, from July 2010 to June 2012. After a 4-week telmisartan (80 mg/d) wash-in, 400 patients continuing on 80 mg/d telmisartan were randomly assigned to additionally receive placebo (Group A), 50 mg/d clopidogrel (Group B), 20 mg/d leflunomide (Group C), or 50 mg/d clopidogrel and 20 mg/d leflunomide (Group D). The 24-week intervention was completed by 360 patients. The primary endpoint was change in 24-h proteinuria at 24 weeks. A linear mixed-effect model was used to analyze the changes at 4, 12, and 24 weeks. Generalized estimating equations were used to evaluate changes in hematuria grade. This trial was registered at the Chinese Clinical Trial Registry. Results:The effects of telmisartan combined with leflunomide on changes in proteinuria (0.36 [95% confidence interval (CI) 0.18–0.55] g/d, P < 0.001), in serum uric acid (76.96 [95% CI 57.44–96.49] &mgr;mol/L, P < 0.001), in serum creatinine (9.49 [95% CI 6.54–12.44] &mgr;mol/L, P < 0.001), and in estimated glomerular filtration rate (−6.72 [95% CI −9.46 to −3.98] ml[BULLET OPERATOR]min−1[BULLET OPERATOR]1.73 m−2, P < 0.001) were statistically significant, whereas they were not statistically significant on changes in systolic and diastolic blood pressure and weight (P > 0.05). Telmisartan combined with clopidogrel had no statistical effect on any outcome, and there was no interaction between the interventions. No obvious adverse reactions were observed. Conclusions:Telmisartan combined with leflunomide, not clopidogrel, is safe and effective for decreasing proteinuria in certain IgAN patients.

肾脏病早期,大多没有症状.如果没有注意尿色的异常、尿量的变化,或没有出现明显的水肿、腰痛,往往就不会引起人们的重视.这时,不进行尿液常规检查的话,很难在早期发现是否患有肾脏病.本文就易患肾脏病的情况及应注意的临床细节进行分析. 中老年人容易罹患继发性肾小球病 中老年人容易罹患继发性肾小球病,例如糖尿病肾病、高血压肾损伤、骨髓瘤肾病等.已经患上了糖尿病、高血压、高脂血症、痛风或高尿酸血症的患者,或是长期吸烟者、肥胖者,如果对血糖、血压、血脂等指标控制不好,逐渐出现了微量白蛋白尿或持续蛋白尿,就说明已经进入了慢性肾脏病阶段.
<正>骨-矿物质代谢异常是慢性肾脏病(Chronic kidney disease,CKD)常见并发症之一。近年来,人们发现成纤维细胞生长因子23(Fibroblast growth factor 23,FGF23)在CKD早期就参与了血磷代谢的调节;并被证实与终末期肾脏病(End stage renal disease,ESRD)患者的高死亡率和高心血管事件发生率相关。本文就FGF23在肾脏病领域的研究进展作一综述。1 FGF23分子结构和生理功能FGF23属于FGFs家族中一员,相对分子质量为32 000,基因定位于染色体12p13,共有3个外显子及2个内含子,编码糖蛋白产物含251个氨基酸,首先切除前24个氨基酸信号肽链,随后经GALNT3酶
BACKGROUND:Family members of patients with end stage renal disease were reported to have an increased prevalence of chronic kidney disease (CKD). However, studies differentiated genetic and non-genetic family members are limited. We sought to investigate the prevalence of CKD among fist-degree relatives and spouses of dialysis patients in China.METHODS:Seventeen dialysis facilities from 4 cities of China including 1062 first-degree relatives and 450 spouses of dialysis patients were enrolled. Sex- and age- matched controls were randomly selected from a representative sample of general population in Beijing. CKD was defined as decreased estimated glomerular (eGFR<60 mL/min/1.73 m2) or albuminuria.RESULTS:The prevalence of eGFR less than 60 mL/min/1.73 m2, albuminuria and the overall prevalence of CKD in dialysis spouses were compared with their counterpart controls, which was 3.8% vs. 7.8% (P<0.01), 16.8% vs. 14.6% (P=0.29) and 18.4% vs. 19.8% (P=0.61), respectively. The prevalence of eGFR less than 60 mL/min/1.73 m2, albuminuria and the overall prevalence of CKD in dialysis relatives were also compared with their counterpart controls, which was 1.5% vs. 2.4% (P=0.12), 14.4% vs. 8.4% (P<0.01) and 14.6% vs. 10.5% (P<0.01), respectively. Multivariable Logistic regression analysis indicated that being spouses of dialysis patients is negatively associated with presence of low eGFR, and being relatives of dialysis patients is positively associated with presence of albuminuria.CONCLUSIONS:The association between being family members of dialysis patients and presence of CKD is different between first-degree relatives and spouses. The underlying mechanisms deserve further investigation.
Objective To understand the blood pressure variability (BPV) and the influencing factors through ambulatory blood pressure monitoring during hemodialysis (HD) in the end-stage renal disease (ESRD) patients.Method Eighty-one ESRD patients on maintenancing HD for more than three months were enrolled into the study.The patients were with properly dry body weight.The blood pressure was monitored using dynamic blood pressure monitor around the HD.BPV was estimated with the coefficient of variation (CV) and standard deviation (SD) of the systolic blood pressure (SBP-CV,SBP-SD).Patients were divided into two groups according to the mean of SBP-CV:high SBPV group and low SBPV group.The possible influencing factors such as age,dialysis duration,ultrafitration volume,ultrafiltration/body weight,therapy of antihypertensive,electrolyte,nutrition state,metabolic bone disease indexes,inflammatory state and serum lipid state were analyzed and compared between the two groups.And multivariate stepwise regression analysis was made between the SBP-CV,SBP-SD and the above observational parameters.Results The average SBP-CV of the 81 patients was (8.12± 3.16)%,SBP-SD was (11.22±4.55) mm Hg.The proportion of hypertention and hypotention in high SBPV(SBP-CV≥8.12%) group (20.0%,25.7%) was higher than that in the low SBPV(SBP-CV <8.12%) group (8.7%,6.5%)(P =0.009).Serum high-sensitivity c-reactive protein (hs-CRP) and alkaline phosphatase (ALP) were higher in high SBPV group than that in the low SBPV group[(7.19± 5.95) mg/L vs (3.35±2.78) mg/L,P =0.001 and (180.31±96.32) U/L vs (98.00±41.19) U/L,P =0.049].Serum creatinine and potassium were higher in the low SBPV group than that in the high SBPV group [(1015.83±276.20) μmol/L vs (893.63±216.61) μmol/L,P =0.034 and (5.27±0.78) mmol/L vs (4.80± 0.23) mmol/L,P =0.005].SBP-SD was positively correlated with hs-CRP (β =0.499,P < 0.01),SBP-CV was positively correlated with hs-CRP and dialysis vintage (β =0.464 and 0.211,P < 0.01 and P < 0.05) by the multivariate stepwise regression analysis.Conclusions The SBP-CV during HD is 8.12% in ESRD patients.Hypertention and hypotention are more often in the higher SBPV patients.SBPV is closely related to the serum hs-CRP.

Drugs are a double-edged sword, which can both treat the disease and cause damage to kidney and other organs. The predisposing factors of drug-induced renal injury include lack of effective volume of circulating blood, the original kidney damage, the elderly, and the joint use of nephrotoxic drugs. Early drug-induced renal injury may not show obvious symptoms, signs, or only show abnormal levels of biomarkers such as urinary neutrophil gelatinase-associated lipocalin(NGAL), kidney injury molecule-1(Kim-1), and interleukin-18(IL-18), etc. During the course of medication, regular test of these indicators will help early detection of drug-induced renal injury. To prevent or reduce drug-induced renal injury, we should be familiar with the drug features, adverse drug reactions as well as the patients' physical condition, strictly control the medication indications, and adhere to rational use of drugs.
