An attack of acute neuro-Behçet's disease during the course of chronic progressive neuro-Behçet's disease: report of two cases

A Systematic Review of Neurocognitive Functioning in Behçet's Disease

Behçet's disease (BD) is a vascular, inflammatory multisystem disorder with neuro-Behçet's (NBD) diagnosed in a subset of patients with neurological manifestations. The objective of this review was to determine whether neurocognitive dysfunction is observed in BD, in which neurocognitive domains, and whether there are differences in rates of dysfunction observed between BD and NBD groups. Studies of any methodology were included that reported results from standardized neurocognitive assessment measures in participants with BD or NBD. Twelve group comparison studies met the criteria for inclusion in the review (totalling 284 BD and 157 NBD participants), as well as 17 case study/series papers (11 BD, 35 NBD). Issues with blinding, incomplete data reporting and selective reporting bias were found across the group and case study/series papers, as well as inadequate statistical adjustment for multiple comparisons in the group studies, and the lack of the use of appropriate norms or adjustment for premorbid ability in the case series/studies papers. These quality issues impacted on the conclusions that could be drawn from the current literature. Neurocognitive dysfunction was found in NBD compared to health controls (HC) in a higher proportion of results across studies, than in comparisons between BD and HC groups. The domains in which neurocognitive attenuation was most often reported were visual spatial ability, working memory and acquired knowledge, with more than 25% of these results showing significantly lower functioning in both the BD and NBD groups compared to HC. More than 25% of the processing speed and long-term memory encoding and retrieval results were also lower for the NBD group, compared to HC. Group comparisons between NBD and multiple sclerosis participants indicated few significant differences in neurocognitive test results. The majority of case study/series participants were found to have some degree of attenuated neurocognitive functioning, as defined by case study/series authors.

Ptosis and Mass Like Lesions in Behçet's Disease: A Rare Presentation

In this article, we describe a case of neuro-Behçet's disease presenting with unilateral ptosis and facial paresis due to an intracranial mass lesion. A 25-year-old male patient with a history of Behçet's disease presented with headache, vertigo, double vision, ptosis in his right eyelid and slurred speech. Cranial magnetic resonance imaging scan revealed a right-sided capsulothalamic lesion, which was extending to the right cerebral pedicle, pons and superior cerebellar pedicle. This lesion was interpreted as neuro-Behçet's disease involvement of central nervous system. Cerebral mass- like lesion is a rare form of neuro-Behçet's disease. Review of the literature revealed a limited number of cases. Ptosis related with Behçet's disease is also a very rare presentation. This case shows that this symptom might be a part of the clinical presentation of neuro-Behçet's disease.

Distinct clinical features between acute and chronic progressive parenchymal neuro-Behçet disease: meta-analysis

Neuro-Behçet’s disease (NBD) is subcategorized into parenchymal-NBD (P-NBD) and non-parenchymal-NBD types. Recently, P-NBD has been further subdivided into acute P-NBD (A-P-NBD) and chronic progressive P-NBD (CP-P-NBD). Although an increasing number of studies have reported the various clinical features of A-P-NBD and CP-P-NBD over the last two decades, there was a considerable inconsistency. Two investigators systematically searched four electrical databases to detect studies that provided sufficient data to assess the specific characteristics of A-P-NBD and CP-P-NBD. All meta-analysis was carried out by employing the random-model generic inverse variance method. We included 11 reports consisted of 184 A-P-NBD patients and 114 CP-P-NBD patients. While fever (42% for A-P-NBD, 5% for CP-P-NBD, p < 0.001, I² = 93%) was more frequently observed in A-P-NBD cases; sphincter disturbances (9%, 34%, P = 0.005, I² = 87%), ataxia (16%, 57%, P < 0.001, I² = 92%), dementia (7%, 61%, P < 0.001, I² = 97%), confusion (5%, 18%, P = 0.04, I² = 76%), brain stem atrophy on MRI (4%, 75%, P < 0.001, I² = 98%), and abnormal MRI findings in cerebellum (7%, 54%, P = 0.02, I² = 81%) were more common in CP-P-NBD. Cerebrospinal fluid cell count (94/mm³, 11/mm³, P = 0.009, I² = 85%) was higher in A-P-NBD cases. We demonstrated that A-P-NBD and CP-P-NBD had clearly different clinical features and believe that these data will help future studies investigating P-NBD.

Severe panuveitis in neuro-Behçet's disease in Malaysia: a case series

Behçet’s disease (BD) is a multisystemic disease that is very rare in Malaysia. About 5% of patients develop central nervous system involvement, termed neuro-Behçet’s. Neuro-Behçet’s is one of the most serious causes of long-term morbidity and mortality. We report two cases of neuro-Behçet’s associated with uveitis (ocular BD) highlighting the clinical presentation, diagnostic measurement, and therapeutic management of these cases.

Infliximab is a plausible alternative for neurologic complications of Behçet disease

Objective:

We evaluated the effectiveness of infliximab in patients with neuro-Behçet syndrome for whom other immunosuppressive medications had failed.

Methods:

Patients whose common immunosuppressive medications fail in recurrent neuro-Behçet syndrome need an alternative. We report our experience with the tumor necrosis factor α blocker infliximab for long-term treatment of neuro-Behçet syndrome. We recruited patients within a multidisciplinary referral practice of Behçet disease and prospectively followed everyone with a neurologic symptom(s). Patients (n = 16) with ≥2 neurologic bouts (excluding purely progressive disease) while on another immunosuppressive treatment were switched to and successfully sustained on infliximab (5 mg/kg in weeks 0, 2, and 6, then once every 8 weeks; minimum follow-up duration ≥12 months). Infliximab was stopped within 2 months after initiation in one patient because of pulmonary and CNS tuberculosis.

Results:

Patients had stepwise worsening due to relapses in the Expanded Disability Status Scale modified for neuro-Behçet syndrome before switching to infliximab (median score of 5.0, range 2.0–7.0; median neuro-Behçet syndrome duration 29.1 months, range 5.0–180.7). Median duration of preinfliximab immunosuppressive medication use was 20.0 months (range 3.0–180.7). In all 15 patients, during infliximab treatment (median score 4.0, range 2.0–7.0; median duration 39.0 months, range 16.0–104.9 months), neurologic relapses were completely aborted and there was no further disability accumulation.

Conclusion:

We observed a significant beneficial effect of infliximab in neuro-Behçet syndrome.

Classification of evidence:

This study provides Class IV evidence that for patients with neuro-Behçet syndrome whose other immunosuppressive medications failed, infliximab prevents further relapses and stabilizes disability.
