Heart Disease and Stroke Statistics—2019 Update: A Report From the American Heart Association

Isoform composition of antithrombin in a covalent antithrombin-heparin complex.

Pulmonary thromboembolism (PTE) is rare in neonates and infants; however evidence suggests it is underdiagnosed. The primary objective is to conduct a scientific review to determine if the presentation, diagnosis, treatment and outcomes of neonates and infants with PTE are consistent across studies. Secondly, to develop an algorithm to establish the diagnosis and management of the condition based on current information. Two authors searched the literature independently using existing databases and verified that identical articles were assembled. Infants aged less than 1 year with PTE were included and further categorized into neonates 28 days or less and infants 29 days to 1 year or less. Forty-five articles with 157 cases (121 neonates; 36 infants) were identified with PTE. All of the reports were descriptive and neither randomized controlled trials nor prospective or case-control studies were identified. The reports are sub-classified into cases of pulmonary air embolism (PAE) with a higher mortality rate and patients with PTE. Diagnostic and treatment strategies varied widely and were individually case-based, dependent on clinical findings, which influenced patient outcomes. Scientific data to guide an evidence-based, diagnostic and treatment approach to PTE is limited because of the absence of rigorous clinical trials. Large scale, multicenter collaborative studies are required to firmly establish the management of PTE in this population.

Neonatal and infant pulmonary thromboembolism: a literature review.

Antithrombin-heparin covalent complex reduces microemboli during cardiopulmonary bypass in a pig model.

We have developed a covalent antithrombin-heparin (ATH) complex with advantages compared to non-covalent antithrombin: heparin (AT:H) mixtures. In addition to increased activity, ATH has a longer intravenous half-life that is partly due to reduced plasma protein binding.GivenATH’s altered clearance,we investigated biodistribution of ATH in vivo. ATH made from either human plasma-derivedAT (pATH) or recombinant human (produced in goats) AT (rhATH) was studied. 125I-ATH + unlabeled carrier was injected into rabbits at different doses. 131 Ilabeled albumin was administered just before sacrifice as a marker for trapped blood in tissues. Immediately after sacrifice, animal components were removed, weighed, and subsamples were counted for gamma-radioactivity. Percent recoveries of ATH in various organs/compartments at different time points were calculated, and kinetic distribution plots generated. At saturating doses, early disappearance of rhATH from the circulation was much faster than pATH. Co-incident with clearance, 26 ± 3 % of dose for rhATH was liver-associated compared to only 3.7 ± 0.5 % for pATH by 20 min.Also, at early time periods, > 60 % of all extravascular ATH was liver-associated. Analysis of the vena cava and aorta suggested that vessel wall binding might also account for initial plasma loss of rhATH. By 24 h, most of pATH and rhATH were present as urinary degradation products (51 ± 3 % and 63 ± 8 %, respectively). In summary, systemic elimination ofATH is greatly influenced by the form ofAT in the complex, with liver uptake and degradation playing a major role.
