RESUMEN
BACKGROUND: Herpes zoster (HZ) is a common infection in individuals with acquired immunodeficiency syndrome (AIDS) patients. Traditional Chinese medicine (TCM) has been used widely in clinical practice for HZ, which remains not supportive of evidence. This review aimed to evaluate the effectiveness and safety of TCM in treating HIV-associated HZ. METHODS: Nine electronic databases were searched for randomized controlled trials (RCTs) testing TCM in treating HIV-associated HZ. Data were extracted on citations, interventions, and outcomes, by two authors independently. For the quality evaluation, Cochrane risk-of-bias tool 2.0 was used. Meta-analyses were performed by Revman5.3 software. Effect estimation presented as risk ratio (RR) for dichotomous data and mean difference (MD) for continuous data with their 95% confidence interval (CI). RESULTS: Twelve RCTs (n = 644) were included; the majority of them had a high or unclear risk of bias. Meta-analysis showed that pain intensity (VAS 0-5) in the Chinese herbal medicine (CHM) group was lower than it in the drugs group (MD = -0.87, 95% CI [-1.69, -0.04], two trials, n = 93). Duration of herpes-related pain (days) of patients in the combination group was shorter than those in the drugs group (MD = -9.19, 95% CI [-16.73, -1.65], n = 144). The incidence of postherpetic neuralgia (PHN) in the combination group was lower than in the drugs group (RR = 0.49, 95% CI [0.25, 0.99], n = 202). As for cure rate (complete absence of pain and herpes), two trials showed that CHM was better than drugs (RR = 1.58, 95% CI [1.13, 2.22], n = 93), five trials showed combination treatment was better than drugs (RR = 1.40, 95% CI [1.08, 1.82], n = 224). The cure rate in the acupuncture group was more than that in the drugs group (RR = 1.99, 95% CI [1.18, 3.36], n = 120). Four trials reported adverse effects and found no serious adverse events occurred. CONCLUSION: CHM and acupuncture demonstrate more benefits than drugs in pain relief, cure rate improvement, and incidence reduction of PHN. However, given the data limitation and TCM therapies' diversity, the conclusions need to be verified in future trials.
RESUMEN
BACKGROUND: Myasthenia Gravis (MG) is a disorder of neuromuscular transmission bringing mild ocular weakness to severe generalized muscle weakness and disability. The conventional treatments have long-term side effects, and Chinese herbal medicines (CHM) have shown possible effect and safety for MG patients, but the existing evidence was not robust enough and the results were out of date. METHODS: Searching for randomized controlled trials (RCTs) was conducted in 7 databases and clinical trial registries until July 2021. The ROB 2 tool was used to assess the study quality and GRADE was used to assess the quality of whole evidence. Meta-analyses were conducted and the results were presented as risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI). RESULTS: Nineteen RCTs (1283 participants) testing 13 kinds of CHM with adequate randomization were included and six RCTs investigating Compound Huangqi were included in the meta-analyses. In addition to conventional treatment, nine CHMs reduced symptom scores of MG. Compound Huangqi plus conventional treatment (pyridostigmine bromide or prednisone or both) reduced the symptom scores compared with conventional treatment (MDâ¯=â¯-3.56, 95%CI -4.86 to -2.26). Less adverse events happened in the CHM groups (3/247 in the CHM groups, 52/245 in the control groups, RRâ¯=â¯0.13, 95%CI 0.06 to 0.30, 9 RCTs, a total of 492 participants). The effect on quality of life was inconsistent. CONCLUSION: Nine CHMs could probably bring benefit for MG symptom improvement. Moderate to low certainty of evidence supported Compound Huangqi added-on conventional treatment probably bring extra benefit of improving MG symptoms. Adding CHMs could be safer than giving only conventional treatment. STUDY REGISTRATION: The protocol was registered in PROSPERO (ID: 32718).
RESUMEN
ETHNOPHARMACOLOGICAL RELEVANCE: Extract from Kushen (Sophora flavescens Aiton) and Baituling (Heterosmilax japonica Kunth), Compound Kushen Injection has a long history for cancer treatment in China. As a common adjunctive drug in chemotherapy of non-small cell lung cancer (NSCLC), the evidence of effectiveness and safety of Compound Kushen Injection needs to be synthesized. AIM OF THE STUDY: The objective of this overview is to synthesize recent evidence and assess the methodological quality of systematic reviews (SRs) of Compound Kushen Injection, in treating NSCLC as an adjunctive treatment of chemotherapy. MATERIALS AND METHODS: We searched PubMed, PubMed Central, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform and VIP China Science and Technology Journal Database from inception to April 22, 2020. We included SRs of the efficacy and safety of Compound Kushen Injection combined with chemotherapy in the treatment of NSCLC. Two authors assessed eligibility and extracted data. The quality of SRs was assessed using AMSTAR-2. A meta-analysis was conducted for the original trials where good homogeneity was present. Evidence maps using bubble plots illustrated overall results. The quality of the evidence was graded by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. RESULTS: Twelve SRs were included, with 91 randomized controlled trials and 7466 participants. Overall, the quality of the included SRs was low. Only six SRs reported specific chemotherapy regimens, three using vinorelbine combined with cisplatin (NP), one using paclitaxel combined with cisplatin (TP), one using gemcitabine combined with cisplatin (GP), and one discussed the three regimens in subgroups. Meta-analysis showed that CKI used as an adjuvant to chemotherapy was superior to chemotherapy alone in promoting tumor complete response rate, tumor partial response rate, Kamofsky score, and relieving some chemotherapy related side effects. Evidence mapping showed that Kushen Injection combined with NP and GP had better effect. The evidence quality of increasing Kamofsky score and decreasing the incidence of leukopenia were moderate, others were low or very low. CONCLUSIONS: There are some favorable effects in improving short-term effectiveness, quality of life and alleviating some side effects of chemotherapy in patients with NSCLC. Results are more promising when Compound Kushen injection is used as an adjunctive to NP and GP. Promising results are however, compromised by the poor quality overall of the clinical trials.
