Key result

Circulating betatrophin levels were significantly elevated by 4.1 to 5.4 times in Japanese patients with type 1 and type 2 diabetes compared to healthy controls.

Why the study?

Are circulating betatrophin levels elevated in patients with type 1 and type 2 diabetes compared to healthy controls?

Population

76 Japanese subjects including 12 healthy controls, 34 patients with type 1 diabetes, and 30 patients with…

Overview

Elevated betatrophin in Japanese diabetes patients is hypothesis-generating; leaves open biomarker or therapeutic utility pending prospective validation.

Structured PICO

Are circulating betatrophin levels elevated in patients with type 1 and type 2 diabetes compared to healthy controls?

P
Population
76 Japanese adults, comprising 34 with type 1 diabetes, 30 with type 2 diabetes, and 12 healthy controls, evaluated for circulating betatrophin levels.
C
Comparator
Healthy controls (n=12)
O
Outcome

Main Result

Effect estimate: 4.1 to 5.4 times higher

p-value: p=<0.001

Circulating betatrophin is significantly elevated in Japanese patients with type 1 and type 2 diabetes and correlates with glucose and triglyceride levels.

Limitations

  • Retrospective study based on a small number of patients
  • Could not examine lipid profiles and lipoprotein lipase (LPL) in detail
  • Potential variability in results depending on the specific ELISA kit used (N-terminus vs C-terminus reactivity)
  • Could not examine lipid profiles and LPL in detail

Cite This Study

Yamada et al. (2015) conducted a cross-sectional in Type 1 and Type 2 Diabetes (n=76). Diabetes mellitus vs. Healthy controls was evaluated on Circulating betatrophin levels (4.1 to 5.4 times higher, p=<0.001). Circulating betatrophin levels were significantly elevated by 4.1 to 5.4 times in Japanese patients with type 1 and type 2 diabetes compared to healthy controls.
