RESUMEN
Central precocious puberty (CPP) is a common pediatric endocrine disease caused by premature activation of the hypothalamic-pituitary-gonadal axis, featured by rapid development of internal and external reproductive organs and secondary sexual characteristics in girls before age 8 and boys before age 9.The gonadotropin-releasing hormone analogue (GnRHa) is the first choice for the treatment of CPP.Currently, 3.75 mg/ month sustained -release short-acting dosage form (1M depot formulations) is the most commonly used in China.The development of long-acting dosage form will reduce injection times and clinic visits.At present, the 3-month long-acting dosage form (11.25 mg 3M depot formulations) of Leprorelin microsphere has been approved in China.However, clinical practice experience of 3-month Leuprorelin acetate depot formulations is lacking in China.Therefore, in this paper, existing clinical evidence for this dosage form was reviewed to provide evidence-based medicine support for its clinical application.
RESUMEN
Hepatic glycogen storage diseases (GSDs) are a group of rare inherited disorders of glycogen metabolism.Currently, since there is no specific treatment, nutritional therapy becomes the most effective way to reduce and relieve clinical symptoms.Although all types of hepatic GSDs are mainly treated with raw cornstarch, for different subtypes of hepatic GSDs, specific treatment strategies and management are different, so as to the key issues concerned during the follow-up.Therefore, attention should be paid to the long-term nutritional management of patients with different types of hepatic GSDs.
RESUMEN
The relationship between vitamin D deficiency and idiopathic central precocious puberty (ICPP) has been recently documented. In this study, 280 girls diagnosed with ICPP and 188 normal puberty control girls of similar ages were enrolled and retrospectively studied. The ICPP group had significantly lower serum 25-hydroxyvitamin D (25[OH]D) levels than the control group. Furthermore, a nonlinear relationship was found between serum 25[OH]D and ICPP, and a cut-off point for serum 25[OH]D was found at 31.8 ng/ml for ICPP with and without adjusting the different confounding factors. Girls with serum 25[OH]D ≥ 31.8 ng/ml had a lower odds ratio (unadjusted: OR 0.36, 95% CI 0.15 to 0.83, P < 0.05; height and weight adjusted: OR 0.44, 95% CI 0.18 to 1.08, P = 0.072; BMI adjusted: OR 0.36, 95% CI 0.16 to 0.84, P < 0.05). The ICPP subjects with 25[OH]D deficiency had a higher body mass index (BMI) than the subjects from the two other subgroups. Correlation analysis showed that vitamin D level is correlated with BMI and some metabolic parameters in the ICPP group. Our study suggested that vitamin D status may be associated with ICPP risk and may have a threshold effect on ICPP.
