Catastrophic antiphospholipid syndrome presenting as bilateral central retinal artery occlusions

Case of catastrophic antiphospholipid syndrome presenting as neuroretinitis and vaso-occlusive retinopathy

BACKGROUND

Ocular involvement in catastrophic antiphospholipid syndrome (CAPS), a rare, life-threatening form of antiphospholipid syndrome (APS) that results in multiorgan failure and a high mortality rate, has rarely been reported.

CASE PRESENTATION

A 15-year-old girl presented with sudden vision blurring in both eyes. She had marked optic disc swelling and macular exudates in the right eye and intra-arterial white plaques, a few retinal blot hemorrhages, and a white ischemic retina in the left eye. Systemic examination revealed she had acute kidney injury with thrombotic microangiopathy (TMA), multiple cerebral infarcts, valvular dysfunction, and a high titer of triple aPL. Thus, she was diagnosed with CAPS involving the brain, eyes, heart, and kidneys. Plasma exchange and the administration of glucocorticoids, immunoglobulin, warfarin, and rituximab brought a sustained recovery of the TMA, visual symptoms, and echocardiographic findings.

CONCLUSIONS

Ocular involvement of both vaso-occlusive retinopathy, an APS-related thrombotic microangiopathy, and neuroretinitis, a non-thrombotic microangiopathy, can occur as an initial presentation of CAPS.

Catastrophic Antiphospholid Syndrome - An Unusual Case Report

Antiphospholipid syndrome (APLS) is characterised by venous or arterial thrombosis and/or adverse pregnancy outcome in the presence of persistent laboratory evidence of antiphospholipid antibodies. Catastrophic Antiphospholipid Syndrome (CAPS) is a severe and rare form of antiphospholipid syndrome characterised by multiple site thrombosis involving small, medium and large blood vessels occurring over a short period of time (usually 1 week) causing multiorgan failure.

We present an unusual case of left upper limb acute arterial thrombosis with purpura fulminans like skin lesions precipitated by swine flu (H1N1) infection with adult respiratory distress syndrome subsequently developing acute renal failure, retinal infarcts, multiple acute cerebral infarcts, cardiac valvular vegetations and hemolytic anemia with recurrent bleeding episodes. A positive lupus anticoagulant confirmed the diagnosis of CAPS. In spite of early initiation of triple therapy (anticoagulation, high dose steroids, plasmapheresis) our patient did not survive. This rare case of probable CAPS is presented with an aim to study the clinical manifestations, laboratory findings, efficacy of therapy and prognosis in the medical ICU.

Coexistence of antiphospholipid antibodies and cephalalgia

Background

The occurrence of antiphospholipid antibodies (aPLs) and headache comorbidity in the presence or absence of underlying autoimmune diseases remains unclear.

Aim

The aim of this review was to summarize the relationship between headache and aPLs based on evidences from cohort studies and case reports, in addition to examining the treatment strategies that resolved headache in aPLs-positive individuals.

Methods

A comprehensive literature search was conducted through PubMed, ISI Web of Science and Google Scholar. A total of 559 articles were screened and the appropriate articles were selected based on quality and level of evidence.

Results

Cohort studies (n = 27) from Europe, North America and Asia demonstrated comorbidity of aPLs and headache in antiphospholipid syndrome, systemic lupus erythematosus (SLE) and neuropsychiatric SLE patients. Significantly higher association between migraine and aPLs was observed (n = 170/779; p < 0.0001) in individuals without any underlying diseases. Our analysis of shortlisted case reports (n = 17) showed that a higher frequency of anticardiolipin antibodies were present in subjects with different autoimmune disorders (70.6%). Corticosteroids were highly effective in resolving headache in aPLs-positive individuals.

Conclusion

Higher frequency of comorbidity between aPLs and headache was observed in healthy individuals and patient cases. Therefore, experimental studies are warranted to evaluate the aPLs-induced pathogenic mechanism of headache.
