Abstract
Background and objectives The association between body iron stores and risk of deep vein thrombosis/ pulmonary embolism (DVT/ PE) has not been studied among Indian subjects. This study aimed to evaluate the same and also study the association between iron stores and recanalization of affected veins at week-12. Methods This Case-Control with follow-up study enrolled 85 consecutive adult (≥ 18 years) cases presenting with first episode of spontaneous, proximal lower extremity DVT/ PE and 170 age (± 3 years) and sex matched adult controls without DVT/ PE. Those with haemoglobin(Hb) < 9 g/dl, malignancies, serum creatinine ≥ 2 mg/dL, heart failure and concurrent infections/ inflammatory disorders were excluded. All participants underwent iron profile, serum ferritin light-chain (FtL) and hepcidin testing. Results Anaemia [OR = 2.3 (95% CI = 1.3-4.0), p = 0.001] and elevated RDW (RDW-CV > 15%) [OR = 2.3 (95% CI = 1.2-4.3), p = 0.012] were significantly associated with increased risk of DVT/ PE. Iron deficiency (ID, defined as serum ferritin < 30 µg/L, along with TSAT < 20%) was not associated with DVT/ PE risk [OR = 0.8 (95% CI = 0.4-1.7), p > 0.05]. Serum FtL in the highest quartile (> 75th centile) was associated with higher risk of DVT/ PE (OR = 5, 95% CI = 2.6-9.6) and levels < 25th centile with protection against DVT/ PE (OR = 0.1, 95% CI = 0.01-0.32), compared to levels between 25th and 75th centiles (referent range). Highest DVT/ PE risk was associated with FtL > 90th centile [OR≈12 (95% CI = 3.9-37.2)]. No associations were noted between serum hepcidin and DVT/ PE risk and ID and DVT recanalization at week-12. Conclusion Higher iron stores, rather than ID, were associated with increased risk of DVT/ PE among those with Hb ≥ 9 g/dL. Anaemia and elevated RDW were also associated with risk of DVT/ PE. ID was not associated with poorer DVT recanalization at week-12.

Abstract
OBJECTIVE To perform a systematic review and meta-analysis of data devoted to the risk of post-thrombotic syndrome (PTS) following direct oral anticoagulant (DOAC) intake. MATERIAL AND METHODS A systematic review and meta-analysis of trials available in the PubMed database were performed in March 2021. Analysis included the reports with known Villalta score for PTS in patients receiving DOACs or alternative anticoagulation. We analyzed the incidence and risk of any form of PTS. RESULTS We found 10 comparative studies comprising 3161 patients. Incidence of PTS under DOAC therapy was 30.8% (95% confidence interval (CI) 22.2-39.3%), severe PTS - 2.2% (95% CI 1.0-3.4%). DOACs were associated with significantly less risk of any form of PTS (odds ratio (OR) 0.57; 95% CI 0.48-0.68; p<0.001) and severe PTS (OR 0.56; 95% CI 0.36-0.87; p=0.010) compared to vitamin K antagonists. Among various DOACs, specified data were available only for rivaroxaban (OR 0.54, 95% CI 0.42-0.71, p<0.001 for any PTS; OR 0.49, 95% CI 0.27-0.89, p=0.019 for severe PTS). The use of flavonoids in adjunction to rivaroxaban was associated with additional risk reduction for PTS (OR 0.14; 95% CI 0.06-0.31; p<0.001). CONCLUSION Moderate quality evidence suggests that DOACs are associated with significant less risk of any PTS and severe PTS compared to VKA in patients with deep vein thrombosis. Among all DOACs, only rivaroxaban has clear data confirming PTS risk reduction. The use of flavonoids in adjunction to rivaroxaban can further improve treatment outcomes.

Predictive factors of venous recanalization in upper-extremity vein thrombosis. PLoS One 2021; 16:e0251269. [PMID: 33983979 PMCID: PMC8118536 DOI: 10.1371/journal.pone.0251269] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Accepted: 04/22/2021] [Indexed: 12/05/2022] Open
Abstract
BACKGROUND Upper extremity venous thrombosis (UEVT) represents about 10% of venous thrombo-embolic disease. This is mainly explained by the increasing use of central venous line, for oncologic or nutritional care. The factors associated with venous recanalization are not known. OBJECTIVE The aim of this study was to investigate prognosis factor associated with venous recanalization after UEVT. METHODS This study included patients with UEVT diagnosed with duplex ultra-sonography (DUS) from January 2015 to December 2017 with DUS evaluations during follow-up. A multivariate Cox proportional-hazards-model analysis was performed to identify predictive factors of UEVT complete recanalization. RESULTS This study included 494 UEVT, 304 proximal UEVT and 190 distal UEVT. The median age was 58 years, 39.5% were women. Clinical context was: hematological malignancy (40.7%), solid cancer (14.2%), infectious or inflammatory context (49.9%) and presence of venous catheters or pacemaker leads in 86.4%. The rate of recanalization without sequelae of UEVT was 38%. For all UEVT, in multivariate analysis, factors associated with complete vein recanalization were: thrombosis associated with central venous catheter (CVC) (HR:2.40, [1.45;3.95], p<0.001), UEVT limited to a venous segment (HR:1.94, [1.26;3.00], p = 0.003), occlusive thrombosis (HR:0.48 [0.34;0.67], p<0.0001), the presence of a PICC Line (HR:2.29, [1.48;3.52], p<0.001), a thrombosis of deep and distal topography (HR:1.70, [1.10;2.63], p = 0.02) or superficial thrombosis of the forearm (HR:2.79, [1.52;5.12], p<0.001). For deep and proximal UEVT, non-occlusive UEVT (HR:2.23, [1.49;3.33], p<0.0001), thrombosis associated with CVC (HR:1.58, [1.01;2.47], p = 0.04) and infectious or inflammatory context (HR:1.63, [1.10;2.41], p = 0.01) were factors associated with complete vein recanalization. CONCLUSION In this study, factors associated with UEVT recanalization were UEVT limited to a venous segment, thrombosis associated with CVC, a thrombosis of deep and distal thrombosis topography and superficial thrombosis of the forearm. Occlusive thrombosis was associated with the absence of UEVT recanalization.
