<b>OBJECTIVEb>To analyze the clinical characteristics of three Chinese cases of Niemann-Pick disease type C patients with neonatal cholestasis as initial presentation, and enhance awareness of Niemann-Pick disease type C among pediatricians.

<b>METHODb>Three sporadic cases with confirmed Niemann-Pick disease type C initially presented as neonatal cholestasis were retrospectively reviewed in this study. Their peripheral blood specimens were collected after obtaining informed consent. All exons and the intron-exon boundaries of NPC1 gene were examined by bi-directional sequencing.

<b>RESULTb>Three patients, 1 female and 2 males, aged from 2 months to 5 years and 10 months, all first complained of jaundice in the neonatal period. Laboratory tests showed total bilirubin and direct bilirubin significantly increased with predominant increase of direct bilirubin. Total bile acid, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were also increased, while high-density lipoprotein cholesterol decreased. All patients were also accompanied by hepatosplenomegaly, with two of them having increased bronchovascular markings in chest X-ray. Two heterozygous changes of NPC1 gene, c.2741G>T +c.3020C>G (p. C914F + p. P1007R), c.2177G>C + c.3734_ 3735delCT (p.R726T + p. P1245RfsX12), and c.2054T>C + c.2128C>T(p.I685T + p.Q710X), were identified in patient 1, 2 and 3, respectively.

<b>CONCLUSIONb>We reported three cases suffered from Niemann-Pick disease type C with initial presentation as neonatal cholestasis in the mainland of China. For newborns with prolonged jaundice in the neonatal period, as well as neonatal cholestasis, hepatosplenomegaly, Niemann-Pick type C should be included in consideration of differential diagnosis. Genetic testing can identify causative mutations for diagnosis.

Niemann-Pick disease is a storage disease characterized by accumulation of sphingomyelin and other lipids, mainly in the reticuloendothelial system. We experienced a case of type A Niemann-Pick disease in a 18-month-old male infant. He showed dyspnea, marked hepatosplenomegaly and developmental retardation. Fundoscopic examination revealed cherry red spots in both macula. Bone marrow aspirates showed characteristic foam cells. Autopsy finding revealed that liver, spleen, lung, lymph node and brain were involved. Reticular infiltration was shown on chest X-ray. We reported a case of type A Niemann-Pick disease with a brief review of the related literature.

BACKGROUND AND OBJECTIVES: Niemann Pick A disease causes a progressive accumulation of sphyngomyelin in several organs and the survival of the patients is usually limited to three years. We describe the outcome of a patient suffering from Niemann Pick A disease, who first underwent an haploidentical bone marrow transplantation, and then intrathecal and I.V injections of mesenchymal cells. METHODS AND RESULTS: While the outcome of bone marrow transplantation was a complete failure, one month after the treatment with the mesenchymal cells the patient improved from the psychomotor and the parenchymal storage perspective. When hypersplenism was solved platelets rose quickly from 20,000 to 120,000/microliter. CONCLUSIONS: Therefore cellular therapy should be considered as a possible choice of treatment of NPA disease.
