Effectiveness of Chinese herbal medicine compared with angiotensin II receptor blockers in patients with diabetic kidney disease: A hospital-based matched cohort study.

Angiotensin II receptor blockers (ARBs) are one of the standard treatments for diabetic kidney disease (DKD). Some patients may opt for Chinese herbal medicine (CHM) of their own free will. However, there is no real-world evidence regarding the effectiveness and safety of CHM. We aimed to explore the effectiveness of CHM for DKD in comparison to ARBs. We enrolled 732 DKD patients (72 used only CHM and 661 used ARBs) from 2007 to 2016, and all patients were followed until December 2016 at China Medical University Hospital in Taiwan. A total of 355 ARB users and 71 CHM users were analyzed after propensity score matching. The estimated glomerular filtration rate (eGFR) after treatment was 84.9 ± 28.1 ml/min/1.73 m2 in CHM users, which was higher than that (67.8 ± 35.4 ml/min/1.73 m2) in ARB users (p < 0.001). The change in the eGFR was -6.0 ± 21.4 ml/min/1.73 m2 in CHM users and -12.9 ± 24.8 ml/min/1.73 m2 in ARB users (p = 0.029). The blood urea nitrogen (BUN) and creatinine levels of patients taking CHM were 22 ± 16 mg/dl and 0.9 ± 0.4 mg/dl, respectively, and were lower than those (30 ± 28 mg/dl and 1.7 ± 2.0 mg/dl) of patients taking ARBs (p = 0.025 and p = 0.003). Using linear regression with adjustments for age, sex, BMI, baseline eGFR, and HbA1c levels, we found that the declines in the eGFR/baseline eGFR and changes in the urine albumin-creatinine ratio (ACR) were comparable between the two groups (p = 0.86 and 0.73). This study suggests that CHM may have comparable effectiveness to ARBs, which provides insights for further investigations.

Integrated Chinese herbal medicine and Western medicine successfully resolves spontaneous subcutaneous emphysema and pneumomediastinum in a patient with severe COVID-19 in Taiwan: A case report.

CASE: Serious complications of severe coronavirus disease 2019 (COVID-19) include subcutaneous emphysema (SE) and pneumomediastinum, which are complicated to treat with conventional Western medicine. We report how combining Chinese herbal medicine (CHM) with Western medicine quickly resolved a patient's COVID-19-associated pulmonary complications, shortened hospital stay and improved quality of life. CLINICAL FEATURES AND OUTCOME: A 59-year-old male with a history of smoking and tumors was diagnosed with COVID-19 in May 2021. At hospitalization, his oxygen saturation (SpO2) was 80%, he had a continuous severe cough, rapid shallow breathing, spontaneous SE and pneumomediastinum. By Day 4 of hospitalization, his condition was worsening despite standard care, so CHM was added. After 3-5 days, his coughing had lessened and supplementary oxygen therapy was de-escalated. Nine days after starting CHM, the SE had completely resolved and the patient avoided intubation. His WHO OS 10-point Scale score had fallen from 6 to 3 points and the modified Medical Research Council Dyspnea Scale score from 4 to 2 points. He was hospitalized for 19 days. At 1 week post-discharge, the patient could handle most of his daily activities and experienced minor shortness of breath only when performing labor-intensive tasks. At 1 month, his work output was restored to pre-COVID-19 levels. CONCLUSION: CHM combined with standard Western medicine improved pulmonary function, respiratory rate, blood oxygen saturation and shortened the hospital stay of a patient with severe COVID-19 complicated by SE and pneumomediastinum.

Coprescription Trends in Western Medicine, Chinese Herbal Medicine and Dental Medicine among Older Adults in Taiwan from 1997 to 2013.

BACKGROUND: Coprescription is a potential medical problem for older adults that could induce polypharmacy and subsequent complications. In Taiwan, Chinese herbal medicine (CHM) is popular among the older adults. Investigating the coprescription trends in Western medicine, CHM and dental medicine is important to avoid possible polypharmacy. METHODS: We analyzed data from the Longitudinal Health Insurance Database 2000 (LHID 2000) in Taiwan. Patients ≥ 60 years old who received coprescription of Western medicine, CHM and drugs for dental care from 1997 to 2013 were included. The odds ratio (OR) and 95% confidence interval (95% CI) were estimated by a logistic regression model for evaluating the correlation between baseline characteristics and coprescription. RESULTS: A total of 266,034 patients were included for the analysis. Most patients receiving coprescriptions lived in the northern Taiwan and with a monthly income lower than 20,000 new Taiwan dollars. The trends in older adults using Western medicine alone or CHM alone decreased over time, but the cohort using dental medicine alone had the opposite result. Decreased trends in coprescription with age were noted. The trends in the proportion of coprescription and the number of days of coprescription increased with the calendar year. Increased trends in the proportion of patients with coprescription were also found, except for the cohort of patients who used both Western medicine and CHM. Patients who were female, and aged 70-79 years were prone to receive coprescription. CONCLUSIONS: Coprescription in older patients is not uncommon in Taiwan. Healthcare providers and policymakers should be aware of the complex coprescription pattern in the older adults.

Chinese Herbal Medicine Decreases Incidence of Cirrhosis in Patients with Non-Alcoholic Fatty Liver Disease in Taiwan: A Propensity Score-Matched Cohort Study.

Objective: Chinese herbal medicine (CHM) is quite popular in Asia. The purpose of this study is to investigate the benefits of decreasing the risk of cirrhosis in patients with non-alcoholic fatty liver disease (NAFLD) by using CHM. Design: We performed a 1:3 propensity score-matched cohort study to analyze patients with NAFLD diagnosed between January 1, 1997 and December 31, 2011 through the Taiwanese National Health Insurance Research Database. Patients who received CHM therapy from the initial date of diagnosis of NAFLD to December 31, 2011 were included in the CHM group. Patients who were not treated with CHM during the same interval were categorized in the non-CHM group. Cox regression model was used to adjust for sex, age, comorbidities, and drug use. Hazard ratios were also compared between the two groups. Results: A total of 13,072 patients were identified after 1:3 propensity score matching. The patients had similar basic characteristics. A lower cumulative incidence of cirrhosis was found in the CHM cohort (log-rank test, p < 0.0001). Finally, 176 patients in the CHM cohort (4.66 per 1000 person-years) and 582 patients in the non-CHM cohort (7.92 per 1000 person-years) developed cirrhosis (adjusted hazard ratios 0.63, 95% confidence interval 0.53-0.75). The effect of CHM to lower cirrhosis incidence was independent of sex, drug use, and comorbidities, including diabetes mellitus, hypertension, and cardiovascular diseases. Patients older than 40 years of age and without comorbidities such as chronic obstructive pulmonary disease, hyperlipidemia, alcoholism, tobacco use, or obesity also benefited from CHM. Conclusions: Our study is the first large-scale investigation in Taiwan that shows the association between patients with NAFLD and cirrhosis prevention after CHM intervention. The results may be useful for treatment and for decision making for patients and clinical doctors. Further restricted trials are needed to support our findings.

Qi deficiency is associated with depression in chronic hemodialysis patients.

OBJECTIVE: Depression is a common bio-psycho-social problem in hemodialysis (HD) patients. Traditional Chinese medicine has been used for symptom management in patients with depression. Identification of the specific constitution in traditional Chinese medicine is critical for personalized care. However, the association between depression and specific constitution in HD patients is unknown. METHODS: We conducted a cross-sectional study in all chronic HD patients (HD for more than 3 months) at China Medical University Hospital in Taiwan. The depression symptom severity was determined using the Beck Depression Inventory II (BDI-II). Clinical patterns in Chinese medicine were determined using the Constitution in Chinese Medicine Questionnaire. The association between constitution and depression was analyzed using logistic regression. RESULTS: We recruited 467 chronic hemodialysis patients, including 219 females and 248 males, with a mean age of 63±12years. The mean duration of HD was 5.8 years. The mean score for the BDI-II was 11 (interquartile range 8-14). The major constitution was Yang-deficiency (43.7%) among these chronic HD patients. Qi-deficiency was correlated with a duration of HD of more than 5.8 years (p=0.04). Qi-deficiency [odds ratio (OR): 4.05, 95% confidence interval (CI): 1.69-9.72, p<0.01] was also associated with depression in logistic regression with adjustments for confounders, including calcium, phosphorus and hemoglobin levels. CONCLUSION: Qi-deficiency constitution in Chinese medicine is associated with depression in chronic HD patients. Further studies are needed to determine whether treating Qi-deficiency integrating Chinese medicine treatment can improve patients' depression symptoms.

Enhanced chondrogenic differentiation potential of human gingival fibroblasts by spheroid formation on chitosan membranes.

Human gingival fibroblasts (HGF) were recently found to be a source of mesenchymal stem cells. Their behavior on a biomaterial has not been reported so far. The effect of culturing HGF on chitosan membranes on their chondrogenic differentiation was investigated in this study. HGF were first cultured on chitosan membranes and spheroid formation of HGF was observed. Next, HGF on chitosan were induced with chondrogenesis induction medium and their chondrogenic differentiation potential was expressed by assessing the expression of chondrogenesis related genes at both mRNA and protein levels by reverse transcription-polymerase chain reaction (RT-PCR) and immunostaining, respectively. We discovered that the chondrogenic differentiation potential of HGF could be enhanced simply by culturing HGF on chitosan membranes. Expression of neural crest and stemness genes were also analyzed by RT-PCR to evaluate the stemness and self-renewal of HGF spheroids. We found that spheroid formation helped to increase and maintain the expression of stemness genes in HGF. To understand the aspects of the chitosan membranes that induced spheroid formation of HGF, mechanical and physical properties of the chitosan membranes were examined. The migration of HGF on chitosan membranes was also monitored to speculate the process of spheroid formation. In addition, the roles of the Rho/Rho-associated kinase (ROCK) pathway and connexin 43 (Cx43) in spheroid formation were explored. Treatment of HGF cultured on chitosan with the ROCK-activity inhibitor Y27632 clearly inhibited spheroid formation, suggesting that the Rho/ROCK pathway was involved in spheroid formation. The increased Cx43 activity of HGF spheroids on chitosan indicated that the gap junction intercellular communication was regulated by spheroid formation. It was concluded that culturing HGF on chitosan may activate the Rho/ROCK pathway, which led to spheroid formation and gap junction regulation. These changes may contribute to the enhanced chondrogenic differentiation potential of HGF on chitosan.
