Cordyceps sinensis (a traditional Chinese medicine) for treating chronic kidney disease.

BACKGROUND: Cordyceps sinensis (Cordyceps, Dong Chong Xia Cao), a herbal medicine also known as Chinese caterpillar fungus, is one of the most commonly used ingredients in traditional Chinese medicine for the treatment of people with chronic kidney disease (CKD). OBJECTIVES: This review aimed to evaluate the therapeutic effects and potential adverse effects of Cordyceps sinensis for the treatment of people with CKD. SEARCH METHODS: We searched the Cochrane Renal Group's Specialised Register to 14 April 2014 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. We also searched CINAHL, AMED, Current Controlled Trials, OpenSIGLE, and Chinese databases including CBM, CMCC, TCMLARS, Chinese Dissertation Database, CMAC and Index to Chinese Periodical Literature. SELECTION CRITERIA: Randomised and quasi-randomised trials comparing Cordyceps or its products with placebo, no treatment, or conventional treatment were considered for inclusion in the review. DATA COLLECTION AND ANALYSIS: Two authors independently assessed data quality and extracted data. Statistical analyses were performed using the random-effects model and the results expressed as risk ratio (RR) for dichotomous outcomes or mean difference (MD) for continuous data with 95% confidence intervals (CI). MAIN RESULTS: We included 22 studies that involved 1746 participants. Among people with CKD who were not receiving dialysis, Cordyceps preparations were found to significantly decrease serum creatinine (14 studies, 987 participants): MD -60.76 µmol/L, 95% CI -85.82 to -35.71); increase creatinine clearance (6 studies, 362 participants): MD 9.22 mL/min, 95% CI 3.10 to 15.34) and reduce 24 hour proteinuria (4 studies, 211 participants: MD -0.15 g/24 h, 95% CI -0.24 to -0.05). However, suboptimal reporting and flawed methodological approaches meant that risk of bias was assessed as high in four studies and unclear in 18 studies, and hence, these results need to be interpreted with caution. AUTHORS' CONCLUSIONS: We found that Cordyceps preparation, as an adjuvant therapy to conventional medicine, showed potential promise to decrease serum creatinine, increase creatine clearance, reduce proteinuria and alleviate CKD-associated complications, such as increased haemoglobin and serum albumin. However, definitive conclusions could not be made because of the low quality of evidence.

Bundled interventions for consumption management and monitoring of personal protective equipment in COVID-19 pandemic in Hong Kong local hospitals.

Since the outbreak of COVID-19 in December 2019, there had been global shortage of personal protective equipment (PPE) supply due to the breakage of supply chain and also the forbidding of PPE exported by various countries. This situation had greatly affected the healthcare services in local hospitals of Hong Kong. To maintain the availability of PPE for healthcare workers in high-risk clinical settings, the cluster management of New Territories West Cluster, Hospital Authority, had implemented a bundle of interventions in controlling and managing the PPE consumption and ensuring its proper use. A Taskforce on Management of PPE was set up in February 2020 with the aim to monitor and manage the use of PPE in five local hospitals and eight general outpatient clinics of New Territories West Cluster, which were governed in a cluster basis, under the COVID-19 epidemic. Interventions including cutting down non-essential services, implementing telecare, monitoring PPE consumption at unit level and PPE stock at the Cluster Central Distribution Centre and forming mobile infection teams were implemented. The updated PPE standards and usage guidelines to clinical staff were promulgated through forums, newsletters and unit visits. The PPE consumption rates of individual unit were reviewed. Significant decrease in PPE consumption rates was noted when comparing with the baseline data. Comparing the data between 20 February and 1 June 2020, the overall PPE consumption rates were reduced by 64% (r=-0.841; p<0.001) while the PPE consumption rates in anaesthesia and operating theatres, and isolation and surveillance wards were reduced by 47% (r=-0.506; p=0.023) and 49% (r=-0.810; p<0.001), respectively. A bundled approach, including both administrative measures and staff education, is effective in managing PPE consumption during major infection outbreaks especially when PPE supply is at risk.

Comparison of efficacy and renal safety of telbivudine and entecavir in treatment-naive elderly patients with chronic hepatitis B.

BACKGROUND: Data comparing the clinical outcomes of telbivudine (LdT) and entecavir (ETV) in elderly patients with chronic hepatitis B are limited. GOALS: The aim of the present study was to compare the efficacy and renal safety of LdT and ETV in treatment-naive elderly (≥ 60 years) patients with chronic hepatitis B. METHODS: A total of 33 patients treated with LdT were consecutively enrolled in the study. Each patient was matched on the basis of age, sex, and baseline hepatitis B virus (HBV) DNA levels with three to four randomly selected controls treated with ETV. RESULTS: Clinical characteristics were comparable between the two groups. Higher cumulative HBeAg-seroconversion rates were observed in the LdT group than in the ETV group after 2 years (50 vs. 20%) and 3 years (50 vs. 26.67%) of treatment (all P<0.0001). Virological response rate at week 24 was significantly lower in the LdT group than it was in the ETV group (54.55 vs. 70.87%, P<0.0001), but no significant difference was noted in long-term cumulative rates of undetectable HBV DNA levels between the two groups (P=0.562). Virological breakthrough occurred in six (18.18%) LdT patients, with no such cases reported in the ETV group (P<0.0001). Antiviral resistance was strongly associated with LdT use and the absence of undetectable HBV DNA at weeks 12 and 24 (P<0.0001). During the study, significant improvement was observed in the estimated glomerular filtration rate and model for end-stage liver disease score in LdT versus ETV group. CONCLUSION: LdT has a lower clinical efficacy for viral suppression and a higher risk of antiviral resistance than does ETV. However, LdT resulted in higher HBeAg-seroconversion rates and better renoprotective effects than did ETV.
