Gonadal function in adolescents and young women with juvenile systemic lupus erythematosus

Abstract

The authors analysed the gonadal function and age of menarche of 23 female adolescents and young women with SLE, and correlated these with clinical, SLEDAI and therapeutic parameters. the presence of one or more clinical and laboratory parameters defined normal gonadal function: normal menstrual cycles with or without dysmenorrhea; elevated cervical mucus length; normal levels of plasma FSH, LH, estradiol, progesterone, prolactin and testosterone; normal urinary hormonal cytology; serial pelvic ultrasound compatible with ovulatory pattern; and present or previous pregnancy. the mean age of menarche (13.5 +/- 1.4 years) was greater than that found among 2578 healthy Brazilian adolescents (12.5 +/- 1.3 years; P = 0.0002). the delay in menarche correlated with an increase in the duration of the disease (P = 0.0085) and the cumulative dose of prednisone (P = 0.0013) used until the appearance of the menarche. the mean phase length in SLE was 31.5 +/- 10.3. Sixteen female (70%) patients showed normal and seven (30%) abnormal gonadal function. Gonadal function was not correlated with parameters of SLE. These results suggest that the patients of this study reach adulthood with a high chance of fertility.Univ São Paulo, Sch Med, Dept Pediat, Pediat Rheumatol Unit,Childrens Inst, São Paulo, BrazilUniv São Paulo, Sch Med, Adolescent Gynaecol Serv, São Paulo, BrazilUniv São Paulo, Sch Med, Dept Pediat, Adolescent Gynecol Serv,Childrens Inst, São Paulo, BrazilWeb of Scienc
