Neonatal polycystic kidney disease:a case report and literature review / 中国新生儿科杂志

ABSTRACT

Objective To study the clinical characteristics and imaging features of perinatal autosomal recessive polycystic kidney disease ( ARPKD) and a systematic review of the literature was performed to improve awareness of the disease. Methods A newborn with infantile ARPKD admitted to the neonatal department of our hospital was studied and her clinical data and imaging features retrospectively reviewed. CNKI, CBMdisc, MEDLINE and Embase databases were searched using autosomal recessive, perinatal and polycystic kidney as keywords. 9 case reports were retrieved from 2005 to 2015 and a total of 9 patients were analyzed. Results The gestational age of patients with infantile ARPKD was from 33 to 37 weeks. 6 of them were diagnosed using prenatal ultrasound and one patient was diagnosed using genetic sequencing. One of 10 infants had a family history, 4 patientsˊ mothers had abnormal pregnancy history (spontaneous abortion or miscarriage) and 7 (70. 0%) patients with respiratory failure needed mechanical ventilation. The ultrasound of all the patients showed enlarged and hyperechogenic kidneys. 9 patients died, and only one patient was alive after renal transplant. Conclusions The characteristics of perinatal APRKD are enlarged and polycystic kidneys, hepatic cysts and liver fibrosis. Infants with this disease have poor outcomes and high mortality rate. Respiratory failure and renal failure are the main causes of death in the neonatal period and early diagnosis and treatment are necessary.
