| Summary: | Abstract Background It has been recognized that primary membranous nephropathy (MN) is related to an increased risk for thromboembolic complications. However, the current evidence supporting prophylactic and therapeutic anticoagulation is too weak to better meet the clinical needs of this patient population. The present review provides some suggestions to guide the decision on anticoagulant management in primary MN patients with a high risk of thrombosis or with thromboembolic complication. Materials and methods We extracted relevant studies by searching the published literature using the Cochrane Library, Medline, PubMed and Web of Science from March 1968 to March 2018. Eligible publications included guidelines, reviews, case reports, and clinical trial studies that concerned the rational management of anticoagulation therapy in the primary MN population. The evidence was thematically synthesized to contextualize implementation issues. Results It was helpful for clinicians to make a decision for personalized prophylactic aspirin or warfarin in primary MN patients when serum albumin was < 3.2 g/dl to prevent arterial and venous thromboembolic events (VTEs). The treatment regimen for thromboembolic complications (VTEs, acute coronary syndrome and ischemic stroke) in primary MN was almost similar to that for the general population with thromboembolic events. It is noteworthy that patients should continue the previous primary MN treatment protocol during the entire treatment period until they achieve remission, the protocol is complete and the underlying diseases resolve. Conclusion The utility of prophylactic aspirin or warfarin may have clinical benefits for the primary prevention of thromboembolic events in primary MN with hypoalbuminemia. It is necessary to perform large randomized controlled trials and to formulate relevant guidelines to support the present review.
