Liver Storage Disease in Iran: A Ten Year Study of Liver Biopsies in Children Medical Center Hospital in Tehran-Iran

Background: Liver storage diseases are rare biochemical and inherited diseases that affect multiorgan systems.
Objectives: This study was performed to determine the rate of storage diseases and their types in liver pathology specimens of subjects who were referred to a tertiary pediatric center.
Patients and Methods: Two pathologists evaluated 2216 pathology specimens (stained with hematoxylin and eosin and periodic acid-Schiff) from subjects who were referred to the largest pediatric tertiary referral center in Iran between 1996 and 2007. Baseline data and clinical and laboratory manifestations were retrieved from the patients' files.
Results: We identified 117 patients who had storage diseases. A combination of clinical and laboratory findings was used to assess the final diagnosis. Glycogen storage disease (GSD) was observed in 85 of cases, compared with lysosomal storage diseases (LSD) in 31 patients and mucopolysaccharidoses in 1 case. LSD was more prevalent in those aged between 1 month and 1 year, whereas GSD was more frequent in those aged between 1 and 6 years. Most of the patients aged between 1 and 6 years. Most patients with LSD and GSD had unknown types of the disease. The most common known types in the LSD and GSD groups were Niemann-Pick disease and GSD type I respectively. The most common clinical and laboratory manifestation was hepatomegaly and abnormal liver enzymes, respectively.
Conclusions: Most of our patients with storage diseases had Gaucher disease. Hepatomegaly and elevated transaminase levels were the most striking finding. However, with regard to the limitations of our methodology, further studies that collect more accurate data are warranted.

• Implication for health policy/practice/research/medical education:
  There is no report of liver storage disease in Iran. This study is the first who report the results of ten years study of liver biopsies in a tertiary care center in Tehran-Iran. This article would be attractive for practitioners and researches who are interested in pediatrics, pediatric endocrinology and pediatric gastroenterology.
