Juvenile hemochromatosis (JH) is a rare condition classified as an autosomal recessive disorder that leads to severe iron absorption. JH usually affects people under the age of 30 and presents symptoms such as chronic liver damage, hypogonadotropic hypogonadism, cardiac diseases and endocrine dysfunctions. The present case reports a 29-year-old Brazilian woman with JH condition due to mutation (g.47G>A), treated with phlebotomies and deferasirox. She presented symptoms such as weakness, skin hyperpigmentation, joint pain in the shoulders and hands and amenorrhea. First laboratory tests showed altered biochemical parameters [serum ferritin (SF): 5696 ng/mL, transferrin saturation (TS): 85%]. After sessions of phlebotomies (450 mL every 15 d), the patient presented partial symptomatic improvements and biochemical parameters (SF: 1000 ng/mL, Hb: 11 g/dL). One year later, deferasirox (15 mg/kg per day) was introduced to the treatment, and the patient showed total symptomatic improvement, with significant clearing of the skin, SF: 169 ng/mL, and TS: 50%. Furthermore, after the combined deferasirox-phlebotomy therapy, magnetic resonance imaging measurements revealed normalized level for liver iron (30 μmol/g; reference value < 36 μmol/g). In conclusion, combined deferasirox-phlebotomy treatment was able to normalize iron levels and improve symptoms.
青少年血色素沉着症(JH)是一种罕见的疾病,归类为常染色体隐性遗传病,会导致严重的铁吸收。JH通常影响30岁以下的人群,表现出慢性肝损伤、低促性腺激素性腺功能减退、心脏病和内分泌功能障碍等症状。本病例报告了一名29岁的巴西女性,因基因突变(g.47G>A)患有JH,接受了放血疗法和地拉罗司治疗。她出现了虚弱、皮肤色素沉着、肩部和手部关节疼痛以及闭经等症状。首次实验室检查显示生化参数改变[血清铁蛋白(SF):5696 ng/mL,转铁蛋白饱和度(TS):85%]。经过多次放血治疗(每15天450 mL)后,患者症状部分改善,生化参数(SF:1000 ng/mL,血红蛋白:11 g/dL)。一年后,开始使用地拉罗司(每天15 mg/kg)进行治疗,患者症状完全改善,皮肤明显好转,SF:169 ng/mL,TS:50%。此外,在联合使用地拉罗司-放血疗法后,磁共振成像测量显示肝脏铁水平恢复正常(30 μmol/g;参考值<36 μmol/g)。总之,联合使用地拉罗司-放血疗法能够使铁水平恢复正常并改善症状。
