Vertebrobasilar Artery Stroke as the Heralding Sign of Systemic Lupus Erythematosus

Three cases of systemic lupus erythematosus presenting with ischemic stroke as the initial symptom: Case reports and literature review

BACKGROUND

Ischemic stroke constitutes a grave complication within the context of systemic lupus erythematosus (SLE), typically manifesting several years postdiagnosis of SLE. Incidents where ischemic stroke precedes and acts as an initial symptom of SLE are comparatively rare in its early stages, and such presentations are frequently misdiagnosed as ischemic cerebrovascular diseases, posing significant diagnostic challenges.

CASE REPORTS

This article presents three cases of young females in whom ischemic stroke emerged as the initial manifestation of SLE. It incorporates a review of 17 case reports published over the past two decades, focusing on patients with SLE where ischemic stroke was a primary symptom. This discussion encompasses the clinical presentation, outcomes, and therapeutic approaches for these patients.

CONCLUSION

In young patients, particularly females presenting with ischemic stroke and especially in cases accompanied by hematologic or multisystemic involvement, there should be heightened vigilance for SLE-induced ischemic stroke. Early diagnosis and treatment significantly enhance patients' quality of life and survival rates.

Ischemic stroke in human immunodeficiency virus-positive patients: An increasingly age-related comorbidity?

Introduction

The global incidence of ischemic stroke among patients with human immunodeficiency virus is increasing. The aim of this controlled case analysis was to study patient characteristics, stroke etiologies, and risk factors in human immunodeficiency virus-positive patients in a medical system with easy access to antiretroviral therapies.

Patients and methods

We conducted a retrospective, observational study of human immunodeficiency virus-positive patients treated in our stroke unit and outpatient clinic in Germany between 2012 and 2018. A control group of all patients treated for acute ischemic stroke in 2018 was used to elicit possible differences in stroke localization, etiology, and distribution of risk factors.

Results

Out of 3615 patients with an acute ischemic stroke, 24 (0.7%) were newly or previously diagnosed as human immunodeficiency virus-positive. Strokes in this cohort were caused by large-vessel disease (37.5%), small-vessel disease (20.8%), cryptogenic-embolism (20.8%), vasculitis (16.7%), and cardio-embolism (4.2%). Large-vessel disease-related strokes were more often located in the posterior circulation (77.8%). Compared to the control group, cardio-embolic strokes were less and vasculitis and large-vessel disease more frequent. Human immunodeficiency virus-positive patients were younger at stroke onset (53.7 ± 12.8 vs. 70.2 ± 14.6 years, p = 0.05).

Discussion

Although the prevalence of human immunodeficiency virus-infection among patients treated for acute ischemic strokes appears low, this collective merits special attention due to a high burden of potentially modifiable risk factors and vasculitis.

Conclusion

Compared to previous studies, age at stroke onset was one of the highest, supporting the hypothesis that as antiretroviral therapy increases the life expectancy of people living with HIV/AIDS, they will be increasingly affected by cardiovascular disease. Human immunodeficiency virus-related cerebral vasculitis was associated with high mortality (75%).

Ischemic stroke as initial manifestation of systemic lupus erythematosus: A case report and review of the literature

Stroke is a frequent occurrence among patients suffering from systemic lupus erythematosus (SLE), but it rarely occurs as the initial manifestation of the disease. We here present the case of a 37 year-old patient who developed an acute cerebellar ischemic stroke as initial event of SLE: elevated partial thromboplastin time and ESR, thrombocytopenia, anti-ds-DNA, anti-SSA, anti-JO-1, and the lupus anticoagulant were detected, and the diagnosis of SLE was established. In addition, we reviewed the literature in order to clarify the demographic, clinical, imaging and outcome characteristics of such a presentation, and found 10 similar cases. Most patients were young (age 31.7 ± 8.5 years) and women (8/11, 72.7%). Stroke most often affected the vertebrobasilar territory (7/11, 63.6%). The stroke mechanism was not clearly defined in these cases. Treatment with immunosuppression and anticoagulation was considered to be a reasonable choice for early secondary stroke prevention. The occurrence of ischemic stroke, primarily in the vertebrobasilar system among young patients, especially women, should always raise suspicion for underlying SLE, and prompt diagnostic investigations to confirm or exclude its presence.

•

Ischemic stroke rarely is the initial manifestation of systemic lupus erythematosus (SLE).

•

It mainly affects young patients, especially women, following the age and gender pattern of SLE

•

The vertebrobasilar territory is disproportionately affected.

•

Immunosuppression and anticoagulation therapy is a rational therapeutic approach to minimize early stroke recurrence.
