ABSTRACT
BACKGROUND: Excessive use of fructose has been incriminated as a risk factor for hepatic steatosis. Procollagen type III N-terminal peptide (P3NP) is a marker for steatohepatitis. Thus, we aimed to assess fructose intake in obese children and its relation to nonalcoholic fatty liver disease (NAFLD) and P3NP. METHODS: Fifty-five obese children were compared to 30 controls. All were subjected to dietary fructose and anthropometric assessment, fasting blood sugar (FBS), fasting insulin (FI) and homeostasis model assessment of insulin resistance (HOMA-IR), lipid profile, uric acid, alanine aminotransferase (ALT), P3NP and abdominal ultrasound. RESULTS: Patients had higher fructose intake which was associated with increased NAFLD grade. There was an increase in P3NP with increased NAFLD grade. P3NP correlated positively with fructose intake (processed sources and total) and caloric intake. CONCLUSIONS: High fructose intake is associated with NAFLD and P3NP may serve as a marker of NAFLD in obese children with a proposed cutoff value of 8.5 ng/mL.

BACKGROUND: B-cell chronic lymphocytic leukemia (B-CLL) is a heterogeneous disease with a highly variable clinical course. Some patients may survive for years without need for therapy while others, although they had early treatment, the outcome is unsatisfactory. The motive to find more reliable prognostic factors apart from stage, age, tumor volume and immunoglobulin heavy chain mutations is of clinical interest. MATERIAL AND METHODS: The study was carried out on 25 CLL patients attending Hematology Clinic at Ain Shams University Hospitals. Peripheral blood sample was taken from each patient for surface CD38 and cytoplasmic zeta-chain-associated protein tyrosine kinase (ZAP-70) by flow cytometry and lipoprotein lipase (LPL) expression by real time PCR. RESULTS: We demonstrated statistically significant association between high level of LPL expression and significantly high LDH level, poor cytogenetic risk, ZAP- 70 expression and response to therapy (p=0.01, 0.02, 0.04 and 0.001 respectively). CONCLUSIONS: LPL expression can serve as a new surrogate prognostic factor for CLL patients and can be used to detect patients who need early treatment.
