Pattern Of Injury

Antiphospholipid antibody syndrome (APS) is an acquired prothrombotic autoimmune disease caused by the presence of antibodies against anionic phospholipids or plasma proteins bound to phospholipids on cell membranes. It can be a primary disease or secondary to other autoimmune diseases, most commonly systemic lupus erythematosus (SLE). Laboratory testing for antiphospholipid antibodies (aPL) may be only transiently positive, so APS could be missed until a catastrophic thrombotic episode or pregnancy morbidity occurs. In the kidneys, this manifests as thrombotic microangiopathy (TMA), and patients present with hypertensive urgency and acute kidney injury. However, APS may not always have a catastrophic presentation but instead a more smoldering course. Kidney biopsy may not show obvious active TMA lesions but rather only chronic injury in the form of zonal cortical scarring and tubular thyroidization. Still, it may warrant anticoagulation therapy. So it is important to recognize this pattern of injury in the biopsy. Herein, we retrospectively study the correlation between presence of this histologic feature in kidney biopsies of SLE patients and positive aPL testing results (anticardiolipin antibodies and/or lupus anticoagulant). Kidney biopsies of SLE patients from 2004 to 2015 ( n = 186) were screened for presence or absence of zonal cortical scarring. Their electronic medical records were reviewed for aPL results. Our study showed low sensitivity (33%) but higher positive predictive value (62%), specificity (89%) and negative predictive value (71%). This histologic finding is therefore not a sensitive screening tool, but if present, greatly increases the likelihood of underlying aPL. We want to emphasize that recognition of this histologic feature in the biopsies of SLE patients is important so as not to miss the opportunity to treat with anticoagulation therapy and possibly slow down the chronic renal damage.

SummaryObjective: To evaluate the usefulness of IgA antiphospholipid antibodies as markers of thrombosis and/or antiphospholipid antibody syndrome. Patients and Methods: A cross-sectional study design in a tertiary, university-based, autoimmune reference hospital. Seven-hundred ninety-five patients classified into five different groups – autoimmune diseases (255), deep vein thrombosis (153), transitory ischemic attacks (108), obstetric complications (196), infectious diseases (83) and controls (81) – were tested for IgA, IgG and IgM aPL, and lupus anticoagulant. Plasma and serum samples were drawn for detection of aPL using an internationally standardized ELISA method and LA was carried out using coagulometric assays. Results: True IgA aPL were found only in two patients with systemic lupus erythematosus; these patients were also positive to IgG aPL. Conclusion: The incidence of true positivity to IgA anticardiolipin antibodies is extremely low. Their determination was not helpful in diagnosing the antiphospholipid syndrome or in explaining thrombotic events or aPL related manifestations – fetal loss – in the groups studied.

Thrombophilic Condition

Catastrophic antiphospholipid syndrome (CAPS) is a rare but highly fatal clinical syndrome that occurs in up to 1% of patients with antiphospholipid syndrome (APS). The diagnosis of CAPS is often delayed because its presentation with multiple organ thromboses can be confused with other thrombotic microangiopathies and severe sepsis. We report a case of CAPS in a patient with APS and systemic lupus erythematosus (SLE) presenting with thrombotic storm precipitated by trauma, cytomegalovirus (CMV) infection, and noncompliance with anticoagulation therapy. Our case reflects the “two-hit hypothesis” of APS in which the presence of antiphospholipid antibodies (first hit) increases the thrombophilic risk, and thromboses take place in the presence of another thrombophilic condition such as CMV infection in our case. In this case review, we discuss the diagnostic challenges and management of CAPS. In clinical practice, we aim to stress the importance of thorough evaluation and management of precipitating events such as infections in addition to timely diagnosis and treatment of this catastrophic clinical entity.

Abstract Background: Although pyoderma gangrenosum (PG) -like lesions have been rarely described in adults with the antiphospholipid antibody syndrome (APS) and systemic lupus erythematosus (SLE), the occurrence of PG as a preceding manifestation of APS in children with SLE has not been reported until. We present a young girl with SLE and APS who developed progressive extstensive ulcerations that were consistent with PG.Case presentation: A 14-year-old girl with a 2-year history of SLE was admitted to our department, complaining painful crusted ulcerations on her legs. Skin biopsy was reported as PG. However, she did not respond to immunosuppressive therapy administered. When her skin biopsy findings is reassessed in keeping with the positive anticardiolipin antibody results, superficial small vessel microthrombosis was observed. Diagnosis of APS and PG developing secondary to SLE were made. It was resulted in marked clinical improvement with anticoagulation therapy in addition to immunosuppressives as is recommended in APS. Conclusions: Based in clinical, pathological and response to proposed treatment, we can state that PG -like lesions in children with SLE could be considered as a secondary form of APS.

Threefold Increase

Antiphospholipid antibodies (aPL): lupus anticoagulant (LA), anticardiolipin antibodies (aCL) and anti-β2-glycoprotein I antibodies (anti-β2GPI) are found in 12 to 44% of systemic lupus erythematosus (SLE) patients. On average, antiphospholipid antibody syndrome (APS) develops in50% of aPL-positive patients with SLE. The seronegative APS is characterized by the absence of the diagnostic levels of "classical" aPL and by the presence of non-criteria aPL: antibodies against pro- thrombin (aPT), antibodies against annexin V, antibodies against phosphatidylethanoamine (aPE), antibodies to phosphatidylserine/prothrombin complex (aPS-PT) and antibodies against negatively charged phospholipids. The presence of four antibodies (LA + aCT + anti-β2GPI + aPT) is associated with a threefold increase in the risk of thrombosis. The presence of aCL and anti-β2GPI in SLE patients with APS and recurrent thromboses is associated with the HLA dRB1 * 0402.

Summary Antiphospholipid syndrome (APS) is an autoimmune disease characterized by antiphospholipid antibodies (aPL) associated with thrombosis and/or pregnancy morbidity. Most APS events are directly related to thrombotic events, which may affect small, medium or large vessels. Other clinical features like thrombocytopenia, nephropathy, cardiac valve disease, cognitive dysfunction and skin ulcers (called non-criteria manifestations) add significant morbidity to this syndrome and represent clinical situations that are challenging. APS was initially described in patients with systemic lupus erythematosus (SLE) but it can occur in patients without any other autoimmune disease. Despite the autoimmune nature of this syndrome, APS treatment is still based on anticoagulation and antiplatelet therapy.

A high functioning 74-year-old man with systemic lupus erythematosus presented to the emergency department with acute anxiety. He was found to have elevated cardiac enzymes and admitted to the cardiology service for investigation. In hospital, he developed an erythematous papular rash, and deteriorated to being somnolent and bedridden. He was found to have new multiterritory ischaemic strokes. It was eventually noted that he had persistent eosinophilia, present even on admission, which had been overlooked as the total leucocyte count was normal. Serology for antiphospholipid antibody syndrome (APS) was positive. He was diagnosed with hypereosinophilic syndrome (HES) secondary to new APS, and responded to high-dose steroids. This case highlights the importance of fully evaluating a leucocyte differential to make a diagnosis of HES. We discuss the definition, clinical manifestations, diagnostic approach and management of this important condition.
