Several studies have suggested that GH increases tumor necrosis factor (TNF)-α production in both children and adults. However, a number of studies have demonstrated a negative correlation between GH and TNF α. The aim of this study is to explore the relationship between endogenous GH secretion and certain pro and anti-inflammatory cytokines in short children undergoing GH stimulation testing for evaluation for GH deficiency. Methods: Plasma growth hormone, TNF α, CRP, IL-6, IL1-β, IL-4 and IL-10 levels are obtained at baseline and every 30 minutes for 150 minutes following two provocative agents (clonidine, and either arginine or glucagon). Results: Among the 23 children, 7 are found to be GH deficient. No significant differences in baseline TNF α levels are found between GH deficient and GH sufficient children. No correlation is identified between TNF α levels and GH levels during stimulation testing. Furthermore, no relationship is found between GH and pro-inflammatory cytokines or GH and anti-inflammatory cytokines. Conclusion: Our results do not demonstrate an acute relationship between endogenous GH secretion and the cytokines examined.展开更多

The patient was a 33-year old primary infertile woman due to male’s factors and underwent her second in vitro fertilization (IVF) cycle using GnRH agonist protocol, and no oocytes harvested on ovum picked-up (OPU) day. The start of gonadotropin usage was on day 8th of her period, and the P level increased rapidly and strangely high from day 8th after gonadotropin usage. The E2 level and follicles grew normally but finally no oocytes harvested. She was diagnosed as late ovarian hyper-stimulation syndrome (OHSS) 7 days after OPU. 20 days after OPU, no menstruation come and a positive urine test of hCG were reported. And the patient was diagnosed as EP by laparoscopy. In conclusion, rapidly increased P level, no oocyte retrieval and late onset of OHSS should be very important clues to diagnose this misdiagnosed EP.展开更多
