Hughes syndrome (the antiphospholipid syndrome): a disease of our time

What you need to know about migraine in Hughes syndrome patients

BACKGROUND

Headache, often migrainous, is common in patients with antiphospholipid antibodies, whether or not they meet Sydney criteria for a definite diagnosis of Hughes syndrome. Migraine may be a harbinger of stroke in this patient population and even refractory migraine may be highly responsive to antithrombotic therapy in this clinical context.

PURPOSE

To summarize what is known to date about managing this important manifestation of the immune-mediated hypercoagulable Hughes syndrome.

RESULTS

We provide a suggested management algorithm for refractory headache in this unique patient population.

CONCLUSION

Most neurologists don't see or recognize many aPL-positive patients in their practice, so hematologists and rheumatologists who see these patients should recognize that refractory headache may be a manifestation of their immune-mediated hypercoagulable disorder and understand that the potential risks of not addressing this issue may be high.

Immunological Risk Factors in Recurrent Pregnancy Loss: Guidelines Versus Current State of the Art

Around 1-5% of all couples experience recurrent pregnancy loss (RPL). Established risk factors include anatomical, genetic, endocrine, and hemostatic alterations. With around 50% of idiopathic cases, immunological risk factors are getting into the scientific focus, however international guidelines hardly take them into account. Within this review, the current state of immunological risk factors in RPL in international guidelines of the European Society of Reproduction and Embryology (ESHRE), American Society of Reproductive Medicine (ASRM), German/Austrian/Swiss Society of Obstetrics and Gynecology (DGGG/OEGGG/SGGG) and the Royal College of Obstetricians and Gynecologists (RCOG) are evaluated. Special attention was drawn to recommendations in the guidelines regarding diagnostic factors such as autoantibodies, natural killer cells, regulatory T cells, dendritic cells, plasma cells, and human leukocyte antigen system (HLA)-sharing as well as treatment options such as corticosteroids, intralipids, intravenous immunoglobulins, aspirin and heparin in RPL. Finally, the current state of the art focusing on both diagnostic and therapeutic options was summarized.

[Lupus and thrombophilia : Antiphospholipid syndrome]

Even early on thromboembolic events were observed in patients with systemic lupus erythematosus (SLE) until the antiphospholipid syndrome (APS) was described in the 1980s as an independent disorder. The APS is a systemic autoimmune disease often overlapping with SLE in which antiphospholipid autoantibodies, including lupus anticoagulant, can cause a hypercoagulation state, which clinically by definition is manifested as arterial and venous occlusions or pregnancy complications. The pathophysiology has not yet been entirely delineated and the clinical spectrum of associated concomitant manifestations is large. As the mortality is increased with SLE and simultaneous APS, focused diagnostics and risk assessment are indispensable. According to the recently published recommendations of the European League Against Rheumatism the therapeutic strategy comprises individualized secondary prevention of thromboembolic complications by means of anticoagulation (with unaltered importance of vitamin K antagonists) and thrombocyte aggregation inhibition, usually lifelong. Statins and antimalarial drugs are recommended for vascular protection while immunosuppressive treatment has not so far been sufficiently proven for APS but remains the subject of current research.

Immune profiling in patients with recurrent miscarriage

The central role of the maternal immune system for successful and disturbed pregnancies such as recurrent miscarriage (RM) is apparent. Recent studies have increased understanding of the complex interaction of the different immunological players and the adaptation of the maternal immune system to the semi-allogeneic embryo. There is growing evidence for immunological abnormalities in RM patients, including autoimmune and allogeneic factors. However, the question remains unsolved whether these changes represent the cause or the consequence of RM. As in half of the RM patients the underlying mechanism remains unknown, further diagnostic methods are urgently needed. Within this review we summarize (recent) literature on the immunological diagnosis in RM patients to find out current trends and to identify potential targets of therapy. As the exact mechanisms of feto-maternal tolerance have not yet been determined we suggest that the immunological diagnosis should be implemented only in well-designed clinical trials in specialized centers to establish a standardized immunological work-up in RM patients.

Leg ulcers in antiphospholipid syndrome secondary to systemic lupus erythematosus treated with intravenous immunoglobulin

BACKGROUND

Despite encouraging reports on the efficacy of intravenous immunoglobulin (IVIg) in antiphospholipid syndrome, the clinical value of this treatment is not well established, and most of the data are based on case reports and small series of patients.

OBSERVATION

We describe the significant improvement of leg ulcers with IVIg in a 61-year-old female, with diabetes mellitus, venous peripherical insufficiency and secondary antiphospholipid syndrome to systemic lupus erythematosus.

CONCLUSIONS

This case illustrates a rare cause of leg ulcers and documents that IVIg may be an effective adjuvant treatment in the management of selected patients with antiphospholipid syndrome when conventional strategies using subcutaneous heparin and low-dose aspirin are insufficient.

Reflections on Lupus 2013: butterflies, wolves and prophecies

The recently concluded Tenth International Congress on Systemic Lupus Erythematosus (SLE) held in Buenos Aires was a resounding success. This overview summarizes some of the origins of the First International Congress held in Calgary, Canada in 1986, predictions offered by past Congress Presidents, and a perspective on the trends in autoantibody testing, which remains one of the key approaches to the early and accurate diagnosis of SLE. The last few decades have witnessed a remarkable proliferation of new diagnostic technologies including addressable laser bead immunoassays and, more recently, chemiluminescence and lateral flow technologies that could find a clinical niche in point-of-care diagnostics. Against the backdrop of these constantly emerging technologies, indirect immunofluorescence has remained the platform of choice for many laboratories and diagnosticians. The notion that autoantibodies are pathogenic has been challenged by evidence that some autoantibodies are protective, some may have catalytic capacity while others may be neutral or have no function at all. The latter notion of functionless or "junk" autoantibodies needs to be taken under some advisement, because there was a time when a great proportion of the human genome was considered to include "junk DNA". The butterfly as a symbol of hope and progress in SLE research over the past 27 years since the First International Congress on SLE is almost certainly to be even more appropriate when future Congresses are held in Geneva (2015), Melbourne (2017) and eventually one in 2050.
