Pelvic Congestion

Pelvic congestion syndrome (PCS) typically causes chronic non-cyclical abdominal pain with a considerable negative effect on the quality of life of women. However, pediatric cases with PCS are limited and non-invasive therapy for adolescent patients has not been reported. We report here a 13-year-old girl who presented with intermittent abdominal pain since the age of 2 years and her symptoms further deteriorated after breast development at 6 years and 9 months old. PCS and coexistent idiopathic central precocious puberty were finally diagnosed on the basis of tortuous ovarian and pelvic veins, and a pubertal response to a gonadotropin-releasing hormone (GnRH) test without hypothalamic–pituitary lesions. After treatment with the GnRH agonist, the pain score was greatly reduced and there was increased prediction of adult height. This case highlights the occurrence of PCS in adolescents and also indicates the role of non-invasive GnRH agonists in young patients with PCS before surgical intervention.

Abstract Objectives To determine appetite-regulating hormone levels in girls with central precocious puberty (CPP) before and after 20 weeks of gonadotropin-releasing hormone analogue (GnRH-A) treatment. Methods Eighteen newly diagnosed CPP girls were enrolled. Body composition measured by bioelectrical impedance analysis and GnRH-A test were performed with fasting serum leptin, ghrelin and peptide YY (PYY) measurements at baseline (before) and after 20 weeks of GnRH-A treatment. Results Following GnRH-A treatment, all patients had prepubertal gonadotropin and estradiol levels. Mean (SD) fat mass index (FMI) was significantly increased from 4.5 (1.7) to 5.0 (1.8) kg/m2 after treatment. Also, median (IQR) serum leptin level was significantly increased from 6.9 (4.2–8.6) to 7.4 (5.3–13.1) ng/mL. FMI had a positive correlation with serum leptin level (r=0.64, p=0.004). In contrast, no significant changes of serum ghrelin and PYY levels were observed. Conclusions Decreased estrogen following short-term GnRH-A treatment in CPP girls may cause an increase in appetite and consequently an elevation of FMI. Increased serum leptin may be a result of having increased FMI secondary to an increase in appetite.

Objective: The aim of this study is to determine the cutoff values of gonadotropin response to gonadotropin-releasing hormone analogs (GnRHas) corresponding to the activation of the hypothalamic–pituitary–gonadal axis that could differentiate central precocious puberty (CPP) from premature thelarche (PT) and using the electrochemiluminescence assay method. Methods: A total of 49 girls underwent the stimulation test with the intramuscular injection of 3.75 mg leuprolide acetate. Based on the clinical and laboratory characteristics, they were divided into two groups: CPP (n = 22) and PT (n = 27). Baseline estradiol, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) were collected before GnRHa administration, and LH and FSH at 60 and 120 min, respectively, after GnRHa administration. Results: The girls with CPP presented an increased height Z-score, advanced bone age, and higher baseline LH, FSH, estradiol, and LH/FSH ratio in relation to PT (p < 0.001). Stimulated LH differed significantly between the two groups, and the LH cutoff values were ≥4.29 IU/L (p < 0.001) and ≥3.95 IU/L at 60 and 120 min, respectively (p < 0.001). LH peak was found at 60 min after stimulation. Conclusions: The GnRHa test is effective in distinguishing CPP from PT, and a single sampling, at 60 min, with LH concentrations above 4.29 may be the parameter of choice with the advantage of greater convenience and practicality.
