Chinese Consensus Report on Family-Based Helicobacter pylori Infection Control and Management (2021 Edition).

OBJECTIVE: Helicobacter pylori infection is mostly a family-based infectious disease. To facilitate its prevention and management, a national consensus meeting was held to review current evidence and propose strategies for population-wide and family-based H. pylori infection control and management to reduce the related disease burden. METHODS: Fifty-seven experts from 41 major universities and institutions in 20 provinces/regions of mainland China were invited to review evidence and modify statements using Delphi process and grading of recommendations assessment, development and evaluation system. The consensus level was defined as ≥80% for agreement on the proposed statements. RESULTS: Experts discussed and modified the original 23 statements on family-based H. pylori infection transmission, control and management, and reached consensus on 16 statements. The final report consists of three parts: (1) H. pylori infection and transmission among family members, (2) prevention and management of H. pylori infection in children and elderly people within households, and (3) strategies for prevention and management of H. pylori infection for family members. In addition to the 'test-and-treat' and 'screen-and-treat' strategies, this consensus also introduced a novel third 'family-based H. pylori infection control and management' strategy to prevent its intrafamilial transmission and development of related diseases. CONCLUSION: H. pylori is transmissible from person to person, and among family members. A family-based H. pylori prevention and eradication strategy would be a suitable approach to prevent its intra-familial transmission and related diseases. The notion and practice would be beneficial not only for Chinese residents but also valuable as a reference for other highly infected areas.

[Amoxicillin-Clarithromycin-Containing Bismuth Quadruple Therapy for Primary Eradication of Helicobacter pylori].

Objective To evaluate the efficacy and safety of amoxicillin-clarithromycin-containing bismuth quadruple regimen as a primary therapy for Helicobacter pylori (Hp) eradication.Methods A total of 102 Hp-infected outpatients diagnosed by 13C-or 14C-urea breath test from December 2015 to June 2017 were enrolled and received 14-day bismuth quadruple therapy (esomeprazole 20 mg bid,bismuth potassium citrate 220 mg bid,amoxicillin 1000 mg bid,and clarithromycin 500 mg bid for 14 days). Hp status was assessed by 13C-or 14C-urea breath test 4 weeks,8 weeks,6 months,and 12 months after the treatment. The primary outcome was Hp eradication rate,which was analyzed by intention-to-treat (ITT) and per-protocol (PP) analyses. The second outcomes were Hp infection recurrence,symptomatic benefit from Hp eradication,and safety. Results A total of 101 patients,of which 65 patients had dyspeptic symptoms before eradication,completed the study. Hp eradication rates by ITT analysis and by PP analysis were 88.2% and 89.1%,respectively. Only in two of 84 patients,who were followed for 8 weeks after eradication,Hp became positive. No Hp recurrence happened at the 6-month and 12-month follow-up and the annual recurrence rate was 2.4%. The symptomatic relief rates at the 4-week,8-week,6-month and 12-month follow-up were 81.5%,75.4%,71.2%,and 70.2% respectively. Eleven of 101 patients had mild and similar side-effects,which were well tolerated.Conclusion Amoxicillin-clarithromycin-containing bismuth quadruple regimen can be used as the standard therapy for Hp eradication.

Effect of e-learning program for improving nurse knowledge and practice towards managing pressure injuries: A systematic review and meta-analysis.

AIM: The aim of this review was to determine the effectiveness of the e-learning programs for improving the knowledge and professional practices of nursing personnel in managing pressure injuries patients. DESIGN: Systematic review and meta-analysis. METHODS: Systematic search was done in EMBASE, SCOPUS, Cochrane library, MEDLINE, Google Scholar, ScienceDirect and Clinicaltrials.gov databases until August 2022. Meta-analysis was carried out using random-effects model, and the results were reported as pooled standardized mean differences (SMD), or odds ratios (OR) with 95% confidence intervals (CIs). RESULTS: Eight studies were included in the analysis. Most of the studies had higher risk of bias. The pooled SMD for knowledge score and for the classification skill were 1.40 (95%CI: 0.45-2.35; I2 = 93.1%) and 1.75 (95%CI: 0.94-3.24; I2 = 78.3%) respectively. The pooled OR for the classification skills was 1.75 (95%CI: 0.94-3.24; I2 = 78.3%). PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

[The efficacy and safety of continuous erythropoietin receptor activator in dialytic patients with chronic renal anemia: an open, randomized, controlled, multi-center trial].

OBJECTIVE: To evaluate the efficacy and safety of continuous erythropoietin receptor activator (C.E.R.A.) once every 4 weeks by subcutaneous administration on hemoglobin (Hb) maintenance in dialytic patients with chronic renal anemia who had been treated with stable dose of erythropoietin (EPO). METHODS: This was an open, randomized, controlled, multi-center trial. All the hemodialysis or peritoneal dialytic patients in EPO maintenance treatment received subcutaneous EPO-ß during the 6-week pre-treatment period to maintain Hb level between 100 g/L and 120 g/L. Eligible patients were randomized (2:1) to accept either C.E.R.A. once every 4 weeks by subcutaneous administration (C.E.R.A. group, n = 187) or subcutaneous EPO-ß 1-3 times weekly (EPO group, n = 94) for 28 weeks (including 20-week dose titration period and 8-week efficacy evaluation period). The starting dose of C.E.R.A. was converted according to the dose of EPO-ß administered in the week preceding the first study drug administration. The primary outcome was the change of Hb level between the baseline and that in the efficacy evaluation period. RESULTS: Totally 253 patients completed the whole 28-week treatment. The change of baseline-adjusted mean Hb was +2.57 g/L for C.E.R.A. group and +1.23 g/L for EPO group, resulting in a treatment difference of 1.34 g/L (95%CI -1.11 - 3.78 g/L). Since the lower limit of 95%CI was greater than the pre-defined non-inferiority margin -7.5 g/L (P < 0.0001), C.E.R.A. once every 4 weeks by subcutaneous administration was clinically non-inferior to EPO regarding the maintenance of stable Hb level. The proportion of patients maintaining Hb level within the range of 100-120 g/L through efficacy evaluation period was similar between the two groups (69.0% for C.E.R.A. group vs 68.9% for EPO group, P > 0.05). The overall incidence of adverse events was similar between the C.E.R.A.(41.7%) and EPO (46.2%) groups (P > 0.05). The safety findings were in accordance with the patients' primary diseases rather than the administration. CONCLUSIONS: Conversion from EPO to C.E.R.A. once every 4 weeks by subcutaneous injection could maintain the Hb in target level in dialytic patients with renal anemia, and it was non-inferior to EPO. In general, subcutaneous administration of C.E.R.A. is well tolerated in dialytic patients with chronic renal anemia.

The Efficacy of Traditional Chinese Medicine Shoutai Pill Combined with Western Medicine in the First Trimester of Pregnancy in Women with Unexplained Recurrent Spontaneous Abortion: A Systematic Review and Meta-Analysis.

BACKGROUND: Shoutai Pill (STP), a famous classic herbal formula documented in traditional Chinese medicine (TCM), is widely available in China for treating unexplained recurrent spontaneous abortion (URSA). This systematic review and meta-analysis aims at evaluating the efficacy and safety of STP in the first trimester of pregnancy in women with a history of unexplained recurrent spontaneous abortion. METHODS: The following eight databases were searched from their establishment to Dec 31, 2019, for randomized controlled trials (RCTs): PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), the Chinese BioMedical database (CBM), Chinese Scientific Journal Database (VIP), and the Wanfang database. The quality of evidence was estimated by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). RESULTS: A total of 12 studies (916 patients) with URSA were contained in this meta-analysis. The forest plot showed that patients treated with Shoutai Pill and western medicine had a significantly lower incidence of early pregnancy loss (RR: 0.42; 95% CI: 0.34-0.52; P < 0.01, I 2 = 0%). Subgroup analysis revealed that different types of TCM syndrome differentiation had the similar results. Also, in the combined group, patients had a lower TCM syndromes and symptoms and serum D-dimer level, while higher incidence of live birth. CONCLUSIONS: Our findings suggest that cotreatment with STP and western medicine might be superior to western medicine alone in the first trimester of pregnancy to prevent miscarriage in women with unexplained recurrent spontaneous abortion, and there was no adverse event in the experimental group reported. However, the methodological quality of included RCTs was unsatisfactory; it is necessary to verify its effectiveness with further more standardized researches of rigorous design.

Treatment efficacy and safety of low-dose azathioprine in chronic active ulcerative colitis patients: A meta-analysis and systemic review.

OBJECTIVE: To evaluate the efficacy and safety of low-dose azathioprine (AZA) in treating patients with chronic active ulcerative colitis (UC). METHODS: A literature search of Medline, Embase, the Cochrane Library, Web of Science, Wanfang Database, CNKI, SinoMed, VIP Chinese Science and the Technology Journals Database was conducted to identify eligible studies that evaluated the efficacy and safety of low-dose azathioprine (AZA) in treating patients with chronic active UC published up to 15 July 2015. Data were extracted from the studies, including clinical efficacy (response rate, adverse drug reaction [ADR] rate, steroid withdrawal rate and relapse rate) and endoscopic improvement (endoscopic remission rate and mucosal healing rate). RESULTS: Six studies with 211 patients were eligible for the analysis. The overall response rates after 6 and 12 months of treatment were 78.0% (95% confidence interval [CI] 71.0-85.0%) and 88.0% (95% CI 80.0-96.0%), respectively. The overall ADR rate was 25.0% (95% CI 18.0-31.0%). Endoscopic response rate was around 85.0%, while the endoscopic remission rates and mucosal healing rates after 6 and 12 months of treatment were above 60.0% and 70.0%, respectively. The steroid withdrawal rate and relapse rate were in moderate to high heterogeneity. Egger's test indicated that there was no publication bias for studies regarding the 6-month response rate and ADR rate. CONCLUSIONS: Low-dose AZA is effective and safe in the treatment of chronic active UC patients. However, randomized controlled trials with large sample sizes are needed to draw definitive conclusions.

Prospective controlled study on mycophenolate mofetil and prednisolone in the treatment of membranous nephropathy with nephrotic syndrome.

BACKGROUND: Retrospective and anecdotal data suggest that mycophenolate mofetil (MMF) might be effective when given as rescue therapy for membranous nephropathy (MN). Prospective controlled data on MMF and prednisolone as primary therapy are lacking. METHODS: A prospective, randomized, controlled, open-label study was performed to investigate the efficacy and tolerability of MMF and prednisolone as primary treatment in MN with nephrotic syndrome. MMF and prednisolone given for 6 months was compared against a modified Ponticelli regimen in 20 patients, with follow up of 15 months. RESULTS: MMF with prednisolone and the comparative immunosuppressive regimen showed similar efficacy in proteinuria reduction, despite a lower cumulative prednisolone dose in the MMF group (3.80 +/- 0.28 vs 9.93 +/- 0.25 g, P < 0.001). Remission (composite of 'complete' and 'partial') rates were 63.6% and 66.7% in the MMF group and control group, respectively (P = 1.000). Serum creatinine and creatinine clearance remained stable during follow up. Cumulative relapse rate was 23.1% at 2 years. Chlorambucil resulted in more leucopenia compared with MMF. CONCLUSION: Data from this pilot study indicate that more than 60% of patients with MN and nephrotic syndrome respond to combined MMF and prednisolone treatment, and suggest potential benefits of MMF as being steroid-sparing and having less adverse effects compared with other commonly used cytotoxic agents.
