Background The advantages of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) in reducing risk of cardiovascular events (CVEs) and delaying end-stage kidney disease (ESKD) in patients with chronic kidney disease (CKD) is well-known. However, the efficacy and safety of these agents in non-dialysis CKD stages 3-5 patients are still a controversial issue. Methods Two investigators (Yaru Zhang and Dandan He) independently searched and identified relevant studies from MED-LINE (from 1950 to October 2018), EMBASE (from 1970 to October 2018), and the Cochrane Library database. Randomised clinical trials in non-dialysis CKD3-5 patients treated with renin-angiotensin system (RAS) inhibitors were included. We used standard criteria (Cochrane risk of bias tool) to assess the inherent risk of bias of trials. We calculated the odds ratio (OR) and 95% confidence interval (CI) for each outcome by random-effects model. A 2-sided p value < 0.05 was considered statistically significant, and all statistical analyses were performed using STATA, version 15.0. This network meta-analysis was undertaken by the frequency model. Results Forty-four randomised clinical trials with 42,319 patients were included in our network meta-analysis. ACEIs monotherapy significantly decreased the odds of kidney events (OR 0.54, 95% CI 0.41-0.73), cardiovascular events (OR 0.73, 95% CI 0.64-0.84), cardiovascular death (OR 0.73, 95% CI 0.63-0.86) and all-cause death (OR 0.77, 95% CI 0.66-0.91) when compared to placebo. According to the cumulative ranking area (SUCRA), ACEI monotherapy had the highest probabilities of their protective effects on outcomes of kidney events (SUCRA 93.3%), cardiovascular events (SUCRA 77.2%), cardiovascular death (SUCRA 86%), and all-cause death (SUCRA 94.1%), even if there were no significant differences between ACEIs and other antihypertensive drugs, including calcium channel blockers (CCBs), β-blockers and diuretics on above outcomes except for kidney events. ARB monotherapy and combination therapy of an ACEI plus an ARB showed no more advantage than CCBs, β-blockers and diuretics in all primary outcomes. In the subgroup of non-dialysis diabetic kidney disease patients, no drugs, including ACEIs or ARBs, significantly lowered the odds of cardiovascular events and all-cause death. However, ACEIs were still better than other antihypertensive drugs including ARBs in all-cause death but not ARBs in cardiovascular events according to the SUCRA. Only ARBs had significant differences in preventing the occurrence of kidney events compared with placebo (OR 0.82, 95% CI 0.72-0.95). Both ACEI/ARB monotherapy and combination therapy had higher odds of hyperkalaemia. ACEIs had 3.81 times higher odds than CCBs (95% CI 1.58-9.20), ARBs had 2.08-5.10 times higher odds than placebo and CCBs and combination therapy of an ACEI and an ARB had 4.80-24.5 times higher odds than all other treatments. Compared with placebo, CCBs and β blockers, ACEI therapy significantly increased Yaru Zhang and Dandan He...
Study design:Here we describe a patient who developed myelopathy due to gouty tophi of the ligamentum flavum in the thoracic spine. We also review similar cases previously reported in the literature.Objective:Our aim was to present a case of myelopathy due to thoracic spinal gouty tophus.Methods:We report the case of a 56-year-old male with history of peripheral gout and renal insufficiency. The patient complained of back pain and paraparesis of the left lower limb. Multiple tophi were noted over several interphalangeal and metatarsophalangeal joints. Neurological examination showed decreased left lower limb strength and a positive Babinski sign. Magnetic resonance imaging of the thoracic spine revealed hypertrophy of the ligamentum flavum at the level of T3/T4, T5/T6, T9/T10, T10/T11 and T11/T12.Results:A thoracic laminectomy at T1-T5 was performed. Chalky white granular material was found in the ligamentum flavum during surgery. Histological analysis of the specimen demonstrated a gouty tophus. The patient's back pain and paraparesis of the lower left limb improved.Conclusion:The clinician should include spinal gout in the differential diagnosis when dealing with patients with gout and axial pain with or without neurologic deficits. If this diagnosis is seriously entertained, then a CT scan or magnetic resonance imaging as well as tissue biopsy may be needed to establish the diagnosis.
Background This study aims to evaluate the effect of a modified approach on severe congenital ptosis treatment. Methods Through anterior approach, Müller muscle was preserved, meanwhile the upper tarsus was suspended to combined fascia sheath (CFS) and levator muscle (LM) complex. The main outcome measures included marginal reflex distance1 (MRD1), palpebral fissure height (PFH), MRD1 regression, MRD1 improvement, and patient self-satisfaction. Results There were 70 patients (90 eyelids) with severe congenital ptosis received treatment of modified operation, including 20 bilateral and 50 unilateral ptosis. The average LF was 2.53 ± 1.06 mm. The preoperative MRD1 and PFH was −0.06 ± 0.76 mm and 4.25 ± 0.85 mm, respectively. The follow-up was at least 6 months with average of 12.67 ± 4.92 months. The immediate postoperative MRD1 and PFH average was 4.52 ± 0.39 mm and 9.24 ± 0.26, respectively. The last follow-up MRD1 and PFH average was 2.43 ± 0.57 mm and 7.16 ± 0.69 mm, respectively, which was improved significantly (P < 0.01). There were variety degrees of MRD1 regression especially in the first month after operation, and the last follow-up MRD1 regression was 2.09 ± 0.67 mm. The lagophthalmos was obvious immediately after operation and regularly released after 6 months. Objective curative effect assessment showed 78 (86.7%) satisfactory eyes, 4 (4.4%) improved eyes, and 8 (8.9%) noneffective eyes. Two noneffective eyes required reoperation of frontalis suspension. Self-satisfaction rate was 93.3%. Parameters analysis showed that LF had positive correlation with last follow-up MRD1 and negative correlation with MRD1 improvement (P < 0.01). Five eyes had levator shorten history, which was associated remarkably with CFS + LM curative effect (P < 0.01). Mean swelling time was 0.53 ± 0.41 months, and no complications were observed until the last visit. Conclusions This modified method gives powerful correction and vivid eyelid contour, featured with simple surgical procedures, few complications, and satisfactory effect, which is worth to wide application.
Background: More and more studies demonstrated that genetic variation at C1GALT1 influences Gd-IgA1 level in IgAN. However, whether the expression of β1, 3-galactosyltransferase (β1, 3Gal-T) was influenced may provide insights into how Gd-IgA1 levels are controlled in IgAN. Methods: Thirty IgAN patients diagnosed in Tianjin Medical University General Hospital from April to September 2018 and 30 healthy volunteers whose age and gender matched with patients were enrolled in this study. Total Gd-IgA1 levels in plasma were determined by ELISA and C1GALT1 levels were determined by RT-PCR. Four databases (PubMed, EMBASE, CNKI, WanFang Medical Network) were searched to identify eligible studies that evaluated a difference in the expression of C1GALT1 in IgAN patients compared with total controls (non-IgAN and health controls). The C1GALT1C1 expression levels, which was indispensable to β1, 3Gal-T of IgA1, was also been compared. Results: Gd-IgA1 levels were remarkable higher in IgAN patients compared with healthy control. The expression levels of C1GALT1 gene were remarkably down-regulated in IgAN patients compared with healthy control. And the mRNA level of C1GALT1 was inversely correlated to Gd-IgA1 levels. In meta-analysis, six articles including 316 participants that analyzed the expression of β1, 3Gal-T were met inclusion criteria. There was no significant difference in the expression of C1GALT1 between IgAN patients compared with controls. And we found patients with IgAN had lower levels of C1GALT1 gene expression in the B cells compared to controls. The C1GALT1C1 levels in the IgAN patients were not different from the levels in the control group, which were unchanged no matter according to different ethnic population, different control group and different cell source. Two studies including 46 persons compared enzymatic activity of β1, 3Gal-T in B cells, and the result showed the β1, 3Gal-T activity was decreased in B cells. Conclusions: We found expression levels of C1GALT1 were remarkably downregulated in IgAN patients and negatively correlated with higher levels of Gd-IgA1. Subsequent meta-analysis validated the low expression and activity of β1, 3Gal-T in B cells in patients with IgAN. However, there was no apparent disparity in the aspect of C1GALT1C1 expression between IgAN and control groups.
The role of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) in reducing the progression of albuminuria and risk of cardiovascular events in hypertensive patients with diabetic kidney disease (DKD) is well-documented. However, the efficacy and safety of these agents in normotensive patients with DKD are still controversial. MEDLINE, Embase, and Cochrane Library were searched for relevant random controlled trials. The odd risk (OR) reductions were calculated with a random-effects model. Decrease in albuminuria, changes in eGFR, major cardiovascular events, and drug-related adverse events were analyzed. Thirteen RCTs including 1282 patients were retrieved. Compared with placebo or other active agent groups, ACEIs or ARBs significantly decreased albuminuria (MD –80.28 mg/d, 95% CI –104.79 mg/d to –55.77 mg/d), and the efficacy is independent of changes in blood pressure and systolic blood pressure at baseline. The result of subanalysis showed the declining of albuminuria was more significantly in normotensive DKD patients with 2DM (p=0.005). No significant differences were found with regard to the declining of evaluated glomerular filtration rate (eGFR) (MD –0.29 ml/min/1.73 m2, 95% CI –2.99 to 2.41 ml/min/1.73 m2). There were no significant differences in the side effect of the drugs such as hypotension and hyperkalemia. This meta-analysis demonstrated that ACEIs or ARBs can decrease albuminuria to varying degree in normotensive patients with DKD, and better response occurred in patients with 2DM.
