Abstract
BACKGROUND Cancer patients who undergo tumor removal, and reconstructive surgery by transfer of a free tissue flap, are at high risk of surgical site infection and ischemia-reperfusion injury. Complement activation through the lectin pathway (LP) may contribute to ischemia-reperfusion injury. Remote ischemic preconditioning (RIPC) is a recent experimental treatment targeting ischemia-reperfusion injury. The study aims were to investigate LP protein plasma levels in head and neck cancer patients compared with healthy individuals, to explore whether RIPC affects LP protein levels in head and neck cancer surgery, and finally to examine the association between postoperative LP protein levels and the risk of surgical site infection. METHODS Head and neck cancer patients (n = 60) undergoing tumor resection and reconstructive surgery were randomized 1:1 to RIPC or sham intervention administered intraoperatively. Blood samples were obtained preoperatively, 6 hours after RIPC/sham, and on the first postoperative day. LP protein plasma levels were measured utilizing time-resolved immunofluorometric assays. RESULTS H-ficolin and M-ficolin levels were significantly increased in cancer patients compared with healthy individuals (both P ≤ 0.02). Conversely, mannan-binding lectin (MBL)-associated serine protease (MASP)-1, MASP-3, collectin liver-1 (CL-L1), and MBL-associated protein of 44 kilodalton (MAp44) levels were decreased in cancer patients compared with healthy individuals (all P ≤ 0.04). A significant reduction in all LP protein levels was observed after surgery (all P < 0.001); however, RIPC did not affect LP protein levels. No difference was demonstrated in postoperative LP protein levels between patients who developed surgical site infection and patients who did not (all P > 0.13). CONCLUSIONS The LP was altered in head and neck cancer patients. LP protein levels were reduced after surgery, but intraoperative RIPC did not influence the LP. Postoperative LP protein levels were not associated with surgical site infection.

Abstract
INTRODUCTION The administration of FVIII leads to inhibitors in up to 30% of patients with hemophilia A (HA), the most severe treatment complication. FVIII-mannosylation fosters the presentation of FVIII to CD4+-T-lymphocytes. Mannose as primary ligand for the mannose-binding lectin (MBL) activates the lectin pathway of complement. MBL2 single nucleotide polymorphisms (SNPs) lead to low peripheral MBL concentrations that may hamper the removal of mannosylated FVIII. OBJECTIVE Investigation of the association between the inhibitor development in hemophilia A and MBL2-SNPs. METHODS In a case-control study the MBL2-SNPs in exon 1 at codons 52, 54 and 57 (C, B, D-Alleles respectively) were determined in 237 patients with severe hemophilia A with and without inhibitors to FVIII (119 vs 118). The association of MBL2-SNPs and the -308 G>A TNF-α-polymorphism with the presence of inhibitors were determined. RESULTS In the inhibitor group higher frequencies of the B allele (codon 54) (OR: 1.77, P < 0.05) were present. Summarising the MBL2 SNPs (alleles B, C and D) as 0, the 0/0 type occurred only in the inhibitor group (frequencies: 0.08 vs 0, P = 0.003). Based on the genetic background a functional immune response phenotype was determined. 11.8% of patients with inhibitors were of the low MBL/high TNF-α phenotype vs 0.03% of the non-inhibitor patients (OR: 3.71). CONCLUSION Data suggest an association of MBL2-SNPs alone or combined with the 308-TNF-α polymorphism in the inhibitor development. Investigations of components of all three complement pathways are required to comprehend their individual and overall contribution to the inhibitor development in HA.

Abstract
PROBLEM The lectin pathway of the complement system may be involved in the pathogenesis of pre-eclampsia. We aimed to investigate changes in serum concentrations of a broad range of lectin pathway proteins during normal pregnancy and their association with pre-eclampsia, placental infarctions and intrauterine growth restriction (IUGR). METHOD OF STUDY We included 51 women with normotensive pregnancies and 54 women with pregnancies complicated by pre-eclampsia. Blood samples were obtained at gestational weeks 16, 33, 37, and after delivery for the normotensive pregnant women and before and after delivery for women with pre-eclampsia. Mannose-binding lectin (MBL), H- and M-ficolin, collectin liver-1 (CL-L1), MBL-associated serine protease (MASP)-1, MASP-2 and MASP-3 and MBL-associated proteins of 19 (MAp19) and 44 (MAp44) kDa were analysed. Clinical information was obtained from medical records. The placentae were examined by two experienced perinatal pathologists. RESULTS Lectin pathway protein concentrations generally increased during normal pregnancy and decreased after delivery in both normotensive pregnant women and women with pre-eclampsia. Exceptions were MASP-3 which increased after delivery in both groups (P < 0.0001) and H-ficolin which increased after delivery in pre-eclampsia (P < 0.0001). H-ficolin (P < 0.0001), M-ficolin (P = 0.005) and MASP-3 (P = 0.03) concentrations were lower in women with pre-eclampsia than in normotensive pregnant women. Low MASP-3 concentrations were associated with placental infarction (P = 0.03) and IUGR (P = 0.04). Low H-ficolin concentrations were associated with IUGR (P < 0.01). CONCLUSION In general, lectin pathway protein serum concentrations increased during normal pregnancy. H-ficolin and MASP-3 may be involved in the pathophysiology of pre-eclampsia and IUGR and could be potential future pre-eclampsia biomarkers.

Abstract
Background Due to the threat from venous thromboembolism (VTE) after major thoracic surgery, especially for cancers, guidelines recommend either heparin sodium (unfractionated heparin) or low-molecular-weight-heparin (LMWH) for those patients at high risk of deep vein thrombosis (DVT). However, risk of bleeding remains a major concern for pre-operative administration of anti-coagulation agents. Therefore, this study aimed to compare the bleeding risk of preoperative administration of LMWH and heparin in patients undergoing video-assisted thoracic surgery (VATS) lobectomy for lung cancer. Methods A retrospective, single-center study was designed. A total of 130 patients diagnosed with lung cancer were included from August 2016 to January 2018. These patients were divided into two groups. The preoperative administration of heparin group (PH group) had received heparin 5,000 IU, BID (twice a day) both pre- and post-operatively. And the LMWH group (PL group) had received LMWH 4,000 IU, QD (once a day) both pre- and post-operatively. These anticoagulants would not be ceased until patient was discharged or 24-hour postoperative chest drainage volume exceeded 500 mL. Both preoperative and postoperative coagulation parameters including platelet count (PLT), hemoglobin value (HGB), international normalized ratio (INR), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), thrombin time (TT), postoperative drainage parameters and intraoperative bleeding volume were compared. Results A total of 62 patients were collected in PH group, while 68 patients comprised PL group. Preoperative coagulation parameters, hematologic data and demographic data were comparable. Preoperative duration of two agents (P=0.414), operation time (P=0.155), postoperative HGB (P=0.943), PLT (P=0.244), INR (P=0.469), PT (P=0.651), TT (P=0.407), FIB (P=0.151), drainage duration (P=0.800), duration of heparin and LMWH (P=0.778) were all comparable between the two groups. Compared with PL group, intraoperative bleeding volume (105.11 and 50.26, P<0.001) and postoperative mean drainage volume (251.52 and 216.90 mL, P=0.025) of PH group were significant more. Postoperative APTT (30.17 vs. 28.20 seconds, P=0.022) was significantly longer in PH group. Conclusions Compared with preoperative administration of heparin, preoperative thromboprophylactic administration of LMWH significantly decreased the risk of intraoperative bleeding in VATS lobectomy.

Factors involved in initiation and regulation of complement lectin pathway influence postoperative outcome after pediatric cardiac surgery involving cardiopulmonary bypass. Sci Rep 2019; 9:2930. [PMID: 30814659 PMCID: PMC6393526 DOI: 10.1038/s41598-019-39742-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2018] [Accepted: 02/01/2019] [Indexed: 11/10/2022] Open
Abstract
Congenital heart disease (CHD) often requires surgical intervention, and is sometimes associated with life-threatening post-operative complications. We have investigated some factors of the innate immune system involved in the initiation or regulation of complement lectin pathway activation (MASP-1, MASP-2 MASP-3, MAp19, MAp44, ficolin-3) and related them to complications and prognosis in 190 pediatric patients undergoing CHD repair with the use of cardiopulmonary bypass (CPB). Patients with MAp44 levels ≤1.81 µg/ml more frequently experienced low cardiac output syndrome (LCOS), renal insufficiency, systemic inflammatory response syndrome (SIRS) and multiorgan dysfunction (MODS). Low MASP-3 (≤5.18 µg/ml) and high MASP-1 (≥11.7 µg/ml) levels were often associated with fatal outcome. Low ficolin-3 concentrations (≤10.1 µg/ml) were more common among patients experiencing SIRS and MODS than in those without complications. However, patients suffering from SIRS and MODS with low ficolin-3 had a much better prognosis (91% survival vs. 37% among other patients; p = 0.007). A discriminating value of 12.7 µg/ml ficolin-3 yielded 8% vs. 60% mortality (p = 0.001). Our data extend the knowledge concerning involvement of proteins of the lectin pathway in development of post-CPB complications. The potential prognostic value of low preoperative MAp44 and high preoperative ficolin-3 seems promising and warrants independent confirmation.
