36 patients suffering from systemic lupus erythematosus (SLE) were subjected to various screening and confirmation tests for the presence of lupus anticoagulants (LA) which are a risk for thrombosis. In five out of the 36 patients (14%) lupus anticoagulants could be found. Five out of the 36 patients (14%) showed increased antiphospholipid antibody (APA) levels whereby only two of these patients were at the same time LA-positive. The specificity, sensitivity and effectiveness of various tests in respect of LA-demonstrability have been assessed and the results taken as the basis for proposal of a largely automated stepwise diagnostic procedure for LA-determination within the routine coagulation laboratory.

Evaluation of MRX PT DOAC as a new screening method for detecting interferences in thrombophilia analyses.

Background: Direct oral anticoagulants (DOACs) can interfere with coagulation analyses, causing erroneous results such as false-positive lupus anticoagulant and false-normal antithrombin, threatening patient safety when overlooked. A test using a prothrombin time quotient method to detect DOAC presence in plasma samples is now commercially available, the MRX PT DOAC, with the result expressed as Clot Time Ratio (CTR).
Objectives: Evaluate the ability of MRX PT DOAC to identify interfering apixaban or rivaroxaban concentrations, identify non-interfering or interfering patient samples, and detect whether a patient is on DOAC treatment.

Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease with an important course due to systemic compromise. SLE is frequently associated with antiphospholipid syndrome, and pulmonary thromboembolism (PE) is particularly common. It is extremely rare for PE to be the initial clinical presentation and even more uncommon for it to coincide with cardiac tamponade, representing a challenge in diagnosis and management.

Background: Current guidelines recommend application of the 99th percentile to determine the cut-off value on at least 120 healthy donors regardless of sex for lupus anticoagulant (LA) ratio of each step. However, a statistically significant difference between the sexes has been found for LA ratio recently.
Objectives: To clarify whether this sex difference in dilute Russell's viper venom time (DRVVT) exists in various detection systems and the necessity of setting sex-specific cut-off values.

Introduction: Systemic lupus erythematosus (SLE) complicated by thrombotic microangiopathy (TMA) and non-cirrhotic portal hypertension (NCPH) is rare. We present a case of a female patient with SLE who developed TMA and NCPH and responded positively to rituximab and plasma exchange treatment.
Case Description: A 53-year-old woman was admitted with 6 h of confusion.
