Poorly controlled pediatric type 1 diabetes mellitus is a risk factor for metabolic dysfunction associated steatotic liver disease (MASLD): An observational study

OBJECTIVES

Recent studies have suggested a link between type 1 diabetes mellitus (T1D) and metabolic dysfunction associated steatotic liver disease (MASLD) in children and adolescent, but longitudinal evidence is lacking. This study aimed to investigate the potential association between poorly controlled T1D and elevated alanine aminotransferase (ALT), serving as a proxy for MASLD in children and adolescents over time.

METHODS

The study included 32,325 children aged 2-17 years with T1D from Germany, Austria, and Switzerland who had undergone at least one assessment of liver enzyme levels recorded in the Diabetes-Patienten- Verlaufsdokumentation registry. Multivariable logistic and Cox regression models were calculated to show possible associations between T1D and elevated ALT values (>26 U/L in males, >22 U/L in females) as a proxy for MASLD.

RESULTS

Children with poorly controlled T1D (HbA1c > 11%) exhibited increased odds of elevated ALT values, after adjustment for age, sex, diabetes duration and overweight (odds ratio [OR] 2.54; 95% confidence interval [CI], 2.10-3.10; p < 0.01). This finding is substantiated by a longitudinal analysis, which reveals that inadequately controlled T1D was associated with a higher hazard ratio (HR) of elevated ALT values compared to children with controlled T1D over an observation period extending up to 5.5 (HR: 1.54; 95% CI, 1.19-2.01; p < 0.01).

CONCLUSION

In conclusion, the current study strongly links poorly controlled T1D in children and adolescents to MASLD irrespective of overweight. This association is not only present cross-sectionally but also increases over time. The study underscores the critical role of effective diabetes management in reducing the risk of MASLD in this population.

Effect of feeding sodium butyrate to beef female cows during pre- and post-partum period on concentrations of glucagon-like peptides in plasma and colostrum

The objective of this study was to evaluate the effect of feeding beef cows with sodium butyrate during the late pregnancy and early post-partum periods on concentrations of glucagon-like peptide (GLP)-1 and 2 in plasma, colostrum, and transition milk. Twelve Japanese Black female cows were fed concentrate feed without (CON; n = 6) or with (BUTY; n = 6) sodium butyrate supplementation at 1.1% of dietary dry matter from -60 d relative to the expected parturition date to 4 d after parturition. Plasma total cholesterol concentration was higher for the BUTY than for the CON (P = 0.04). In addition, plasma GLP-1 concentration was higher for the BUTY than for the CON at 3 d after calving (P < 0.05). This study showed for the first time that GLP-1 is present in the colostrum of Japanese Black cows at higher concentrations as compared to in plasma (P < 0.01). On the other hand, no treatment effect was observed for concentrations of metabolite and hormone in colostrum and transition milk. In summary, feeding beef cows with sodium butyrate during the late gestation and early post-partum period likely increases plasma GLP-1 concentrations post-partum without affecting the components of colostrum and transition milk.
