Antiphospholipid antibodies and lipoprotein(a) in obese children

ACTA PAEDIATRICA, Issue 4 2009
Devis Pascut
Abstract Aim: Antiphospholipid (aPL) antibodies, Lipoprotein(a) [Lp(a)] and obesity are considered three independent risk factors for development of cardiovascular diseases. We investigate the presence of aPL antibodies and the Lp(a) concentration in 190 obese and 30 healthy children divided into prepubertal and pubertal, compared with healthy adults. Results: aPL antibodies were detected in 2.65% of prepubertal and in 2.59% of pubertal obese children. Considering results obtained by Lp(a) test, 4.4% of prepubertal and 5.2% of pubertal obese children and 17.5% of healthy adults were at risk for development of cardiovascular diseases. Conclusion: The presence of various prothrombotic risk factors increases the probability of developing thrombosis. Considering aPL antibodies there is no statistically significant difference among the different considered groups; therefore each category has the same risk factor. The Lp(a) distribution in adults is significantly different from the Lp(a) distribution in prepubertal (p = 0.012) and pubertal (p = 0.029) obese children. There is no significant difference among prepubertal subjects (p = 0.632) as well as pubertal subjects (p = 0.465), independently from the BMI. These results suggest the control of BMI in young population to avoid the presence of the obesity as another independent prothrombotic risk factor to be added to aPL and Lp(a) in the future adulthood.

Abdominal venous thrombosis in neonates and infants: role of prothrombotic risk factors , a multicentre case,control study

BRITISH JOURNAL OF HAEMATOLOGY, Issue 2 2000
Christine Heller
The factor V (FV) G1691A mutation, the prothrombin (PT) G20210A variant, the methylenetetrahydrofolate reductase (MTHFR) T677T genotype, together with fasting homocysteine (HCY) concentration, lipoprotein (Lp)(a), anti-thrombin (AT), protein C (PC), protein S (PS) and anti-cardiolipin antibodies were investigated in 65 consecutively recruited infants (neonate to <,12 months) with renal venous thrombosis (RVT; n = 31), portal vein thrombosis (PVT; n = 24) or hepatic vein thrombosis (HVT n = 10), and 100 age- and sex-matched healthy controls. FV G1691A was found in 14 babies (heterozygous: RVT n = 9, PVT n = 4; homozygous HVT n = 1) and five controls, the MTHFR TT677 genotype together with increased HCY in four infants with thrombosis (RVT n = 2; PVT n = 1; HVT n = 1) compared with one control, and the PT G20210A variant was present in one control only. PC type I deficiency was diagnosed in three patients (RVT n = 2; PVT n = 1) and AT deficiency in two patients (RVT n = 1; PVT n = 1). Three neonates with spontaneous thrombosis showed FV G1691A combined with Lp(a) and the FV G1691A was combined with the PT G20210A genotype in two infants. Additional triggering factors were reported in 27 patients (41·5%). The overall odds ratios (ORs) and 95% confidence intervals (CIs) with respect to the different thrombosis locations were: RVT (OR/CI: 10·9/3·85,31·1; P < 0·0001), PVT (5·47/1·7,17·6; P < 0·0007) and HVT (3·3/0·58,18·7; P = 0·18). The data presented here suggest that genetic prothrombotic risk factors also play an important role in abdominal venous thrombosis during infancy. [source]

Neonatal renal vein thrombosis and prothrombotic risk

ACTA PAEDIATRICA, Issue 7 2010
SL Harris
Abstract A case of extensive deep venous thrombosis in a four a day old infant was presented. Unusually this patient was shown to be heterozygous for three thrombophilia genes; Factor V Leiden, prothrombin and antithrombin gene mutations, the latter being novel. Conclusion: There are no randomized controlled trials to guide management in deep venous thrombosis in the newborn but knowledge of the prothrombotic risk factors may help direct treatment. [source]
