Behcet's disease and multiple arterial aneurysms: 4 case reports

Neurological involvement in patients with systemic autoimmune rheumatic diseases: a descriptive study in an Egyptian cohort

Background

Neurologic manifestations in the systemic autoimmune rheumatic diseases (SARDs) are protean. They add to the disease burden and could contribute to mortality. Increasing awareness about the neuro-rheumatologic syndromes might help with early diagnosis and effective therapy. Our aim is to survey the clinical and imaging patterns of neurological involvement in Egyptian patients with SARDs.

Results

Neurological involvement is common in Behçet’s disease (BD) (12.7%) and systemic lupus erythematosus (SLE) (6.4%) patients compared with other SARDs. Compared with SLE, neurological involvement in BD tends to develop at an older age (31 ± 7.1 versus 28.3 ± 9.6 years = 0.022) with a greater progression risk (13.8% versus 2.6%, P = 0.003). A higher proportion of SLE patients had abnormal neuroimaging without neurological symptoms (15.7% versus 4.3%, P = 0.026, OR = 4.9, 95%CI 1.1–22.4). SLE patients had a higher frequency of seizures (31.3% versus 6.4%, P < 0.001, OR = 6.7, 95%CI 2.7–16.7) and benign intracranial hypertension (9.6% versus 1.1%, P = 0.009, OR = 9.8, 95%CI 1.2–77.7) but a lower prevalence of quadriplegia due to brain insult (1.7% versus 3.2%, P = 0.045, OR = 0.2, 95%CI 0.04–0.9), dural sinus thrombosis (13% versus 33%, P = 0.001, OR = 0.3, 95%CI 0.2–0.6), brainstem syndrome (0.9% versus 6.4%, P = 0.047, OR = 0.1, 95%CI 0–1.1) and cranial neuropathies (9.6% versus 31.9%, P < 0.001, OR = 0.2, 95%CI 0.1–0.5). Concerning neuroimaging, brain atrophic changes were more common (27.4% versus 9.5%, P = 0.002, OR = 3.6, 95%CI 1.6–8.3) while thrombosis was less prevalent (36.3% versus 53.6%, P = 0.016, OR 0.5, 95%CI = 0.3–0.9) in lupus patients. The cerebral cortex was more commonly affected (20.4 versus 4.8%, P = 0.002, OR = 5.1, 95%CI 1.7–15.4) while dural sinuses (14.2% versus 40.5%, P < 0.001, OR = 0.2, 95%CI 0.1–0.5), basal ganglia (1.8% versus 10.7%, P = 0.010, OR = 0.2, 95%CI 0–0.7), diencephalon (0% versus 13.1%, P < 0.001) and brainstem (1.8% versus 22.6%, P < 0.001, OR = 0.1, 95%CI 0–0.3) were less frequently involved in SLE patients. Concerning other SARDs, cranial neuropathies were the most common neurological presentations. Abnormalities in neuroimaging did not correlate with the patients’ clinical presentations.

Conclusions

Neurological presentations associated with SARDs are protean. Neuroimaging abnormalities should be interpreted within the context of the clinical picture and the results of other investigations.

Clinical presentation and treatment outcomes of arterial involvement in Behçet's disease: a single-centre experience

Arterial involvement, although rare, accounts for significant mortality and morbidity in patients of Behçet's disease (BD). There is paucity of data on arterial BD. The objective of this 5-year retrospective cohort study was to examine the clinical presentation, pattern of arterial involvement, and treatment outcome in Indian arterial BD patients. Data on demography, clinical presentation, radiology, instituted therapy, vascular interventions and treatment outcomes were recorded and analyzed. Ten (16.9%) out of 59 patients with BD had arterial involvement in 13 vascular territories [mean age 30 (8) years, 9 (90%) males]. Pulmonary artery was most commonly involved (46%), followed by abdominal aorta (15%), femoral artery (15%), descending thoracic aorta (8%), common iliac (8%), and dorsalis pedis artery (8%). Two patients had multi-territory involvement. The median interval between disease onset and development of arterial aneurysms was 3 years (3 months-12 years). Concomitant deep vein thrombosis was seen in 60% cases. Prednisolone and cyclophosphamide were the most common immunosuppressive therapy used; one patient who relapsed on cyclophosphamide responded to infliximab. Five surgical or endovascular interventions were performed. Four patients (40%) died due to aneurysm rupture-all had a delayed diagnosis, and three had pulmonary artery involvement, with death due to massive hemoptysis. Based on the present study, we concluded that arterial involvement in BD is seen predominantly in males and has a high mortality. Early detection and aggressive treatment with immunosuppression and surgical or endovascular interventions are essential for good outcomes.
