[PMID: 37920213 PMCID: PMC10619915 DOI: 10.3389/fphar.2023.1230604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 09/28/2023] [Indexed: 11/04/2023] Open
Abstract
Objectives: Chronic cough is a frequent condition worldwide that significantly impairs quality of life. Herbal medicine (HM) has been used to treat chronic cough due to the limited effectiveness of conventional medications. This study aimed to summarize and determine the effects of HM on patients with chronic cough. Methods: A comprehensive search of 11 databases was conducted to find randomized controlled clinical trials (RCTs) that reported the effects of HM for patients with chronic cough on 16 March 2023. The primary outcome was cough severity, and the secondary outcomes included cough-related quality of life, cough frequency, total effective rate (TER), and cough recurrence rate. The methodological quality of the included studies was assessed using the Cochrane risk of bias tool, and the certainty of the evidence for effect estimates was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations tool. Results: A total of 80 RCTs comprising 7,573 patients were included. When HM was used as an alternative therapy to conventional medication, there were inconsistent results in improving cough severity. However, HM significantly improved cough-related quality of life and TER and significantly lowered the cough recurrence rate compared with conventional medication. When used as an add-on therapy to conventional medication, HM significantly improved cough severity, cough-related quality of life, and TER and significantly lowered the recurrence rate. In addition, HM had a significantly lower incidence of adverse events when used as an add-on or alternative therapy to conventional medication. The subgroup analysis according to age and cause of cough also showed a statistically consistent correlation with the overall results. The certainty of the evidence for the effect of HM was generally moderate to low due to the risk of bias in the included studies. Conclusion: HM may improve cough severity and cough-related quality of life, and lower the cough recurrence rate and incidence of adverse events in patients with chronic cough. However, due to the high risk of bias and clinical heterogeneity of the included studies, further high-quality placebo-controlled clinical trials should be conducted using a validated and objective assessment tool.

Lee B, Park HJ, Jung SY, Kwon OJ, Park YC, Yang C. Herbal Medicine Maekmundong-Tang on Patients with Nonspecific Chronic Cough: Study Protocol for a Double-Blind, Randomized Controlled Clinical Trial. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:4164. [PMID: 36901170 PMCID: PMC10002217 DOI: 10.3390/ijerph20054164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 02/21/2023] [Accepted: 02/22/2023] [Indexed: 06/18/2023]
Abstract
As the treatment of nonspecific chronic cough with conventional medications that treat cough according to the cause is limited, Maekmundong-tang (comprising Liriopis seu Ophiopogonis Tuber, Pinelliae Tuber, Oryzae Semen, Zizyphi Fructus, Ginseng Radix, and Glycyrrhizae Radix et Rhizoma) has been used empirically in the clinical setting of East Asian traditional medicine. This study is the first to explore the feasibility, preliminary effect, safety, and cost-effectiveness of Maekmundong-tang for nonspecific chronic cough. This study protocol is that of a double-blind, randomized, active-controlled, parallel-group clinical trial for comparing Maekmundong-tang with Saengmaek-san (comprising Liriopis seu Ophiopogonis Tuber, Ginseng Radix, and Schisandrae Fructus), a Korean national health insurance-covered herbal medicine for cough. A total of 30 nonspecific chronic cough patients will participate and receive the assigned herbal medicine for 6 weeks, and clinical parameters will be assessed at weeks 0 (baseline), 3 (midterm assessment), 6 (primary endpoint), 9, and 24 (follow-up). Study feasibility outcomes, including recruitment, adherence, and completion rates, will be assessed. Preliminary effects on cough severity, frequency, and quality of life will be evaluated using outcome measures, such as the Cough Symptom Score, Cough Visual Analog Scale, and the Leicester Cough Questionnaire. Adverse events and laboratory tests will be monitored for safety evaluation, and exploratory economic evaluations will be conducted. The results will provide evidence of Maekmundong-tang in the treatment of nonspecific chronic cough.

Support Care Cancer 2021; 30:1169-1179. [PMID: 34448942 DOI: 10.1007/s00520-021-06506-0] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2021] [Accepted: 08/11/2021] [Indexed: 12/12/2022]
Abstract
PURPOSE Patients who undergo surgery for lung cancer experience a variety of symptoms, such as pain and coughing, which interfere with their postoperative daily functions. However, there may be differences between the perception of symptoms among healthcare providers and patients. This study aimed to investigate patients' experiences after lung cancer surgery and analyze whether the perception of postoperative symptoms among the healthcare providers differed from that reported by patients. METHODS Semi-structured qualitative interviews involving 39 patients who underwent lung cancer surgery at the Sichuan Cancer Hospital were conducted between November 2018 and October 2019. In addition, 22 healthcare providers from the Department of Thoracic Surgery at the hospital answered open-ended questions about their perception of symptoms related to lung cancer surgery. The types and frequencies of symptoms reported by the patients and healthcare providers were compared. RESULTS The most frequent patient-reported symptoms were pain (967 times, 39 patients, 100%), coughing (904 times, 37 patients, 94.87%), shortness of breath (491 times, 35 patients, 89.74%), Disturbed sleep (412 times, 34 patients, 87.18%), and interference while walking (347 times, 36 patients, 92.31%). Of the patient-reported symptoms, the first four were perceived by the healthcare providers, while they interpreted interference while walking as fatigue. CONCLUSION Although the healthcare providers and patients had a certain consensus on the main symptoms, there were differences in perception. Healthcare providers need to pay more attention to postoperative interference while walking.

Abstract
BACKGROUND Cough is a common symptom that occurs in 25% of patients after lung cancer surgery. It might last a long time and degrade the quality of life of patients. Maekmoondong-tang (Bakumondo-to in Japanese or Mai-Men-Dong-Tang in Chinese) is a herbal medicine which has been widely used for respiratory diseases with cough in Korea, China, and Japan. AIMS The aim of the present study is to evaluate the efficacy and safety of Maekmoondong-tang for postoperative cough in patient with lung cancer. METHODS/DESIGN This study is a randomized, double-blind, placebo-controlled, multicenter trial of Maekmoondong-tang. A total of 96 participants will be enrolled and allocated to 2 parallel groups: the Maekmoondong-tang group and the placebo group from 5 university hospitals. The participants will be administered either Maekmoondong-tang or a placebo 3 times a day for 4 weeks. The primary outcome measurement is the change in the Leicester Cough Questionnaire (LCQ) score. The secondary outcome measurements are the changes in the cough visual analog scale and Yin Deficiency Scale. The participants will visit 4 times in total for 4 weeks of trial period. DISCUSSION The present study will be the first multicener study to evaluate the efficacy and safety of Maekmoondong-tang for postoperative cough in patient with lung cancer surgery. The results of this study will provide a new treatment for cough using herbal medicine and will be a reference for planning clinical trial of herbal medicine in patient with cough.
