1. Randomized controlled clinical trial of Shenzhuo Formula in the treatment of macroalbuminuria in diabetic kidney disease and its inflammation-modulating mechanisms.
In a multicenter double-blind, double-dummy RCT (n=120 macroalbuminuric DKD), Shenzhuo Formula achieved proteinuria reduction comparable to irbesartan while better preserving renal function and improving TCM symptom scores, with favorable safety. Multi-omics analyses (Olink proteomics, scRNA-seq) implicated suppression of CX3CL1/MCP-1–mediated inflammation as a mechanistic pathway.
Impact: Provides high-quality randomized evidence for a novel anti-inflammatory therapeutic strategy in DKD with mechanistic validation. Potentially practice-informing if replicated and benchmarked against contemporary standards of care.
Clinical Implications: Shenzhuo Formula could be considered as an adjunct or alternative to ARB therapy for macroalbuminuric DKD where appropriate, pending larger phase 3 trials and head-to-head comparisons with SGLT2 inhibitors and finerenone. Its inflammation-modulating profile may benefit patients with high inflammatory activity.
Key Findings
- In a randomized, double-blind, double-dummy multicenter trial, SZF matched irbesartan for proteinuria reduction.
- Renal function preservation was superior with SZF alongside improvement in traditional Chinese medicine symptom scores.
- Inflammation proteomics and scRNA-seq implicated suppression of CX3CL1/MCP-1 signaling as a mechanism.
- Safety profile was favorable.
Methodological Strengths
- Randomized, double-blind, double-dummy, multicenter active-controlled design with Bayesian analysis
- Integrated mechanistic validation using Olink inflammation proteomics and single-cell RNA-seq
Limitations
- Sample size was modest (n=120) and duration/follow-up details were not specified in the abstract
- Generalizability of a multi-herb formula to diverse healthcare systems and comparison with contemporary DKD standards (SGLT2i, finerenone) remain to be determined
Future Directions: Conduct large phase 3 trials with longer follow-up; directly compare SZF with SGLT2 inhibitors and finerenone; deconvolute active constituents and pharmacokinetics; validate inflammatory signatures as predictive biomarkers.
2. Taxonomic and functional shifts in the microbiome of severely obese, prediabetic patients: Ketogenic diet versus energy-matched standard diet.
In a randomized, energy‑matched trial in severely obese, prediabetic adults, ketogenic diet acutely reduced alpha diversity (loss of Lachnospiraceae; rise in Bacteroidaceae) and reprogrammed functional pathways (energy metabolism, amino acid synthesis, RNA modification, vitamin biosynthesis), with increased serum acetate. These shifts were not observed with an energy‑matched standard diet.
Impact: Demonstrates that macronutrient composition, independent of caloric intake, rapidly remodels microbiome taxonomy and function in high‑risk metabolic states, strengthening causal links between diet and microbiome-mediated metabolic effects.
Clinical Implications: Supports considering ketogenic dietary patterns for short-term metabolic modulation in severe obesity/prediabetes, while monitoring microbiome diversity and metabolite shifts; findings motivate personalized diet-microbiome strategies.
Key Findings
- Ketogenic diet significantly reduced alpha diversity driven by selective loss of Lachnospiraceae and increased Bacteroidaceae.
- Functional gene profiles shifted with KD (energy metabolism, amino acid synthesis, nucleic acid/RNA modification, vitamin biosynthesis), not seen with energy‑matched standard diet.
- Serum acetate levels increased significantly following KD.
Methodological Strengths
- Randomized, energy-matched dietary comparison isolating macronutrient composition effects
- Integrated taxonomic (16S) and functional profiling with serum metabolite assessment
Limitations
- Short-term intervention; durability and clinical metabolic outcomes were not reported
- Sample size and full CONSORT details not provided in the abstract
Future Directions: Longer trials linking microbiome remodeling to glycemic control, insulin sensitivity, and hepatic outcomes; resolve long-term impacts of reduced alpha diversity; integrate metagenomics/metabolomics for mechanistic personalization.
3. Glucagon-Like Peptide-1 Analogues and the Risk of Recurrent Pancreatitis in Diabetic Patients With History of Pancreatitis or Elevated Lipase: Retrospective Cohort Analysis.
In 46,186 high‑risk diabetic patients (prior pancreatitis or elevated lipase), GLP‑1 analogue exposure independently increased recurrent pancreatitis risk (time‑varying HR 1.252, 95% CI 1.178–1.332), persisting after adjustment for confounders. Results align with pharmacovigilance signals and call for caution when prescribing GLP‑1RAs to such patients.
Impact: Addresses a critical safety question for widely prescribed GLP‑1RAs in a very large cohort using time‑varying models, providing actionable risk stratification for high‑risk patients.
Clinical Implications: Avoid or use extreme caution with GLP‑1RAs in patients with prior pancreatitis or elevated lipase; consider alternative agents, informed consent, and close monitoring; integrate pancreatitis risk into shared decision making.
Key Findings
- In a cohort of 46,186 high-risk diabetic patients, GLP‑1 analogue use was associated with higher recurrent pancreatitis risk (time‑varying HR 1.252, 95% CI 1.178–1.332).
- Association remained significant after adjusting for demographics, alcohol use, and pancreatitis‑associated medications.
- Exclusion of prior users around index date minimized immortal time and prevalent user bias.
Methodological Strengths
- Very large cohort with de‑identified, comprehensive health system data
- Time‑varying exposure modeling with multivariable adjustment for confounders
Limitations
- Retrospective observational design susceptible to residual confounding and misclassification
- Indication bias and incomplete clinical detail (e.g., imaging severity) cannot be fully excluded
Future Directions: Prospective, ideally randomized safety studies or active‑comparator new‑user designs in high‑risk patients; develop clinical prediction tools for pancreatitis risk under GLP‑1RA therapy; mechanistic studies on pancreatic susceptibility.
