Impact of nonsteroidal anti-inflammatory drugs on efficacy of anti-PD-1 therapy for primary liver cancer / 南方医科大学学报

OBJECTIVE@#To assess the impact of nonsteroidal anti-inflammatory drugs (NSAIDs) on clinical outcomes of patients receiving anti-PD-1 immunotherapy for hepatocellular carcinoma.@*METHODS@#We conducted a retrospective study among 215 patients with primary liver cancer receiving immunotherapy between June, 2018 and October, 2020. The patients with balanced baseline characteristics were selected based on propensity matching scores, and among them 33 patients who used NSAIDs were matched at the ratio of 1∶3 with 78 patients who did not use NSAIDs. We compared the overall survival (OS), progression-free survival (PFS), and disease control rate (DCR) between the two groups.@*RESULTS@#There was no significant difference in OS between the patients using NSAIDs (29.7%) and those who did not use NSAIDs (70.2%). Univariate and multivariate analyses did not show an a correlation of NSAIDs use with DCR (univariate analysis: OR=0.602, 95% CI: 0.299-1.213, P=0.156; multivariate analysis: OR=0.693, 95% CI: 0.330-1.458, P=0.334), PFS (univariate analysis: HR=1.230, 95% CI: 0.789-1.916, P=0.361; multivariate analysis: HR=1.151, 95% CI: 0.732-1.810, P=9.544), or OS (univariate analysis: HR=0.552, 95% CI: 0.208-1.463, P=0.232; multivariate analysis: HR=1.085, 95% CI: 0.685-1.717, P=0.729).@*CONCLUSION@#Our results show no favorable effect of NSAIDs on the efficacy of immunotherapy in patients with advanced primary liver cancer, but this finding still needs to be verified by future prospective studies of large cohorts.

Treatment of inflammatory bowel disease with Chinese drugs administered by both oral intake and retention enema / 中国结合医学杂志

<p><b>OBJECTIVE</b>To study the clinical effect of Chinese drugs administered by both oral intake and retention enema on inflammatory bowel diseases (IBD).</p><p><b>METHODS</b>Adopting a randomized controlled design, 78 patients were assigned to three groups: 26 patients in group A treated with Chinese drugs given by both oral intake and retention enema, 27 in group B with Chinese drugs given by retention enema only, and 25 in group C with given Western medicine. The changes before and after a 30-day treatment of the patients' symptoms (including diarrhea, abdominal pain, mucous or pus-bloody stool), colonoscopic examination scores and histopathology of the colonic membrane were observed.</p><p><b>RESULTS</b>Group A showed the best outcomes in all the aspects of clinical comprehensive effectiveness. Improvements in the main symptoms, colonoscopic scores and histopathology of the colonic membrane were significantly different from those in groups B and C, respectively (P<0.05). Meanwhile comparisons between groups B and C showed insignificant differences (P>0.05); group B was better in ameliorating tenesmus (P<0.05).</p><p><b>CONCLUSION</b>Through the use of Chinese drugs administered by both oral intake and retention enema to treat IBD, which combined external-internal therapies for both overall regulation and local management, it was confirmed that the Chinese medicine could embody the therapeutic principle of attending to both disease-diagnosis and syndrome-differentiation.</p>
