Case 1: Wolman disease (OMIM No: 278000)
A two months male child with acid lipase enzyme activity deficiency
Clinical presentation: The child presented with clinical suspicion of Wolman disease with hepatosplenomegaly,
calcified adrenal glands, diarrhea and failure to thrive.
Laboratory work up: Acid lipase enzyme activity was found to be deficient (~ 2.1% of mean normal) in leukocytes.
In view of the age of onset and clinical presentation the diagnosis was consistent with Wolman disease.
About the disorder: Both Wolman disease and Cholesteryl ester storage disease are rare autosomal recessive
lysosomal storage disorders caused by a deficient activity of lysosomal acid lipase, the differentiating factor being
the age of onset and clinical presentation. Wolman disease is the early onset form and develops during the first
few weeks or month of life and presents with hepatomegaly, liver disease, adrenal gland calcification, vomiting,
diarrhea, and failure to thrive. The late onset form which is known as Cholesteryl ester storage disease (CESD)
typically presents later in childhood or even adulthood and presents with hepatosplenomegaly, coronary artery
disease, stroke, altered liver function, jaundice, steatosis, fibrosis, cirrhosis and related complications of
esophageal varices, and/or liver failure, anemia and/or thrombocytopenia. Residual enzyme activity of ≤5% of
mean normal is obtained in Wolman disease and 2% - 11% of mean normal is observed in Cholesterol ester storage
disease (CESD).
Prevalence: Wolman disease is estimated to occur in 1 in 100,000 newborns and CESD is 1 in 1, 30,000 live births.
Differentials: Owing to its similarity with other cardiovascular, liver and metabolic diseases, the differential
diagnosis of these disorders can be challenging. The differential diagnosis includes:
Niemann-Pick disease, Types A/B
Gaucher disease
Familial hypercholesterolemia
Chanarin dorfman syndrome

Case 2: Lysinuric Protein Intolerance (LPI) (OMIM No: 222700)
A two years eleven months male child born from a consanguineous marriage presented with hyper ammonia
Clinical presentation: The child presented with an eight month history of daily episodic irritability lasting for up to
twelve hours associated slow congitive regression. The child was being treated for epilepsy with multiple
anticonvulsants without any improvement. His EEG was normal and MRI had shown symmetrical periventricular T2
hyperintensities. On clinical Examination he was pale, ataxic and had mild hepatosplenomegaly.
Prior work up: His serum Ammonia was significantly raised at 840 micromol/l as were plasma ferritin with mild
derangment of liver function. Clinically urea cycle disorder was suspected.
Diagnostic workup: The patient was referred for metabolic work up including urine organic acid analysis, urine &
plasma amino acid analysis. Urine organic acid analysis revealed a 689-fold elevation of orotic acid and 6-fold
elevation of uracil. Plasma amino acid analysis revealed an elevation of alanine, low level of lysine, absence of
ornithine but arginine was within normal limits. Urine amino acid analysis revealed increase in multiple amino acids
including glutamic acid, glutamine, α-amino adipic acid, citrulline, amino butyric acid, cystine, methionine,
phenylalanine, lysine, and arginine, but ornithine was within normal limits.
Treatment: The child showed dramatic improvement in his symptomatology after starting anitscavanging therapy
(Sodium benzoate and Citrulline) and protein restricted diet.
About the disorder: Lysinuric protein intolerance is an autosomal recessive disorder caused by defective cationic
amino acid (CAA) transport at the basolateral membrane of epithelial cells in kidney and intestine. Clinical
symptoms are presented at infancy after weaning from being breast-fed and include hepatomegaly, pancreatitis,
splenomegaly, nausea, vomiting diarrhea, and aversion to protein rich food, impaired intestinal absorption of
cationic amino acids, chronic renal disease, and impaired renal absorption of CAA, mental retardation, postprandial
hyperammonemia, anemia, leucopenia and thrombocytopenia. The patients look as if they have protein deficiency
or malnutrition, loose skin, hypotonia, muscle weakness, interstitial changes on chest x-ray, respiratory
insufficiency and pulmonary hemorrhage.
The phenotypic variability of lysinuric protein intolerance (LPI) has resulted in various differentials.

Urea Cycle disorders
Malnutrition/ malabsorptive diseases
Lysosomal storage diseases (LSDs)
Hemophagocytic lymphohistiocytosis/macrophagic activation syndrome
Autoimmune disorders

Molecular Diagnostics of Infectious Diseases (New Tests)
At Sandor, our goal is to assist clinicians to make quicker decisions in the prognosis and management of different
infections. Molecular identification in clinical settings is a faster method allowing clinicians to avoid prolonged
management based on empiric medication and to implement specific therapy.
Molecular diagnostics based on Nucleic acid based methods detect organism specific DNA or RNA sequences
extracted from the microorganism. Nucleic acid–based tests are qualitative, but quantification methods do exist for
limited pathogens and can be useful for diagnosis and monitoring of response to treatment. Monitoring of any
infection by Real Time PCR [RT-PCR] assay has high end clinical value and utility in pace with critical care. It
detects/quantifies any infectious agent in any type of appropriate sample with high specificity and sensitivity. In
comparison to conventional cultures and serological detection assays real-time PCR assay has admirable
turnaround times. As this technique does not require post PCR processing, chances of false positivity is very
uncommon as compared to conventional PCR.
Some of the advantages of molecular detection by Real Time PCR are:
Wide range of pathogen detection
High sensitivity & specificity
High end clinical value and utility
Viral load monitoring
Low turnaround time compared to conventional methods
Testing of wide range specimen types
Sandor offers the following tests by Real time PCR:
Hepatitis B virus [HBV] detection, viral load and genotyping
Hepatitis C [HCV] detection, viral load and genotyping
Human Immuno deficiency virus [HIV-1] – detection and viral load
Herpes simples virus 1 &2 – detection
Cytomegalovirus[CMV]- viral load
Epstein-Barr virus[EBV]- viral load
Parvo virus B19- viral load

JC virus - viral load
Human adenovirus- viral load
M. tuberculosis complex and non tuberculosis mycobacterium-detection
