A 12-month-old female child was admitted with fever, cough, and shortness of breath. Her history included recurrent pneumonia. On examination, she had respiratory distress, hepatosplenomegaly, and low weight. Tests found elevated lipids and bone marrow cells resembling Niemann-Pick cells. The child was suspected of having Niemann-Pick Disease type B, a rare genetic disorder caused by a lipid metabolism enzyme deficiency. Type B presents in infancy with lung and liver involvement. No specific treatment exists but management focuses on supportive care.

and normal HB Electrophoresis.
 U/S Abdomen shows mild Hepatospleno-meglly.
 CXR shows BL pulmonary infiltrates
 Bone marrow morphology revealed Large
vacuolated cells resembling Bubble like
appearance depicting Niemann-pick cells.

36.  Child is suspected Niemann Pick Disease
type-B on the basis of clinical manifestations
and characteristic cells on Bone marrow
report.
 Acid sphingomylinase enzyme activity could
not be seen due to lack of facilities.

38.  NPD is autosomal recessive LIPID storage
disorder that results from the deficiency of a
lysozomal enzyme ACID SPHINGOMYLINASE.
 Which involves breakdown transport and use
of fats and cholesterol in body.
 Abnormal metabolism causes harmful
amount of lipids to accumulate in the liver,
spleen, lung, bone marrow and Brain.

latter in childhood.
1. Hepatospenomegaly
2. Pulmonary
involvement in form
of Recurrent
pneumonia
3. Pancytopenia on CBC
due to
hypersplenism
TYPE-C

present with severe
hepatic disease and
pulmonary disease
leading to
respiratory failure.

filpin stain positivity in cultured cell fibroblasts and
identification of a specific mutation in the NPC1 or
NPC2 gene.

chorionic villi.

44.  pancytopenia
 Respiratory failure
 Cor pulmonale
 Bronchopneumonia
 Cirrhosis, portal hypertension, Ascites

45.  No specific treatment is available .
 BONE MARROW TARNSPLANTATION in small
number of type-B NPD patient have been
successful in reducing the sphingomylinase
content of viscera's, Niemann-pick cells in
bone marrow and radiological detected
infiltration of the lung.

recombinant human Acid sphingomylinase is
currently in clinical trials for the treatment of
type-B NPD
 MIGLUSTAT has been approved for the
treatment of type-C NPD .
 Treatment of type A NPD has not been
successful because of the severe neurological
involvement
