The objective of this study was to describe the prevalence and outcome of disease-related serositis in Chinese patients with systemic lupus erythematosus (SLE). The records of all SLE patients who attended the medical clinics of Tuen Mun Hospital, Hong Kong were retrospectively reviewed. Patients with disease-related serositis at any stage of their illness were identified and the outcome of these serositis episodes was reported. Three-hundred and ten patients (90% women) who fulfilled at least four of the ACR criteria for SLE were studied. The mean age of SLE onset was 32.6 +/- 13.1 years. sixty-nine episodes of SLE-related serositis occurred in 37 patients - 18 (26%) episodes were pericarditis/ pericardial effusion, 30 (44%) were pleuritis/pleural effusion and 21 (30%) were peritonitis/ascites. The prevalence of serositis was 12%. At the time of serositis, 34 (92%) patients had active SLE in other systems. Nonsteroidal anti-inflammatory drugs (NSAIDs) were initially used in 13 (35%) patients. Moderate to high doses of oral prednisolone was used in 28 (76%) patients for both serositis and concomitant disease activity in other organs. All episodes of serositis resolved completely within two months. Over a mean observation of 46 months, nine patients had 18 relapses of serositis, which were responsive to either NSAIDs or augmentation of prednisolone dosage. Pleural fibrosis developed in three patients. Serosal complications are not uncommon in patients with SLE and can be life-threatening. NSAIDs and corticosteroids are often effective but more aggressive immunosuppressive therapy is required for severe or refractory cases. The prognosis of lupus serositis is generally good. Relapse or progression to fibrotic disease is uncommon.

Purpose: To determine the long-term outcome of ischemic stroke patients with concurrent intracranial and extracranial atherosclerosis using magnetic resonance angiography. Methods: A prospective cohort of patients in Hong Kong with acute ischemic stroke was studied with magnetic resonance angiography of the brain and carotid duplex. All patients were followed up regularly for the development of recurrent stroke, cardiac events, or death. Results: Totally 343 patients with acute ischemic stroke were included, of whom 104 (30%) had concurrent intracranial and extracranial lesions. The follow-up period was up to 76 months (mean 44.5 months). Overall, 55 patients (15.5%) died of any cause and 91 patients (26.5%) suffered a further nonfatal vascular event. The overall 5-year cumulative rates of mortality, restroke and poor outcomes (combined death and further vascular events) were 18, 27 and 37%, respectively. In patients with concurrent lesions, these rates were 31, 41 and 51%, respectively. The corresponding rates were 13, 22 and 31% in patients without concurrent lesions. The risks were highest in the first year after stroke. More deaths (log rank, 16.3; p = 0.0001), restrokes (log rank, 9.71; p = 0.002) and poor outcomes (log rank, 13.87; p = 0.0001) were found among patients with concurrent lesions. The presence of concurrent vascular lesions, advanced age, smoking, hyperlipidemia and previous history of stroke were independent predictors of poor outcomes. Conclusions: The long-term prognosis of ischemic stroke patients with concurrent atherosclerosis of intracranial and extracranial vessels is poor. They are at high risk of further vascular events or death.

Gabapentin did not produce a significant reduction in symptom severity compared with placebo over an eight-week period.

Background and Purpose-Concurrent atherosclerosis of the intracranial and extracranial cerebrovascular system is common in Asians. The typical lesion patterns and the mechanisms of stroke in patients with concurrent stenoses are unclear. This study aimed to determine these stroke features of such patients in Hong Kong. Methods-We conducted a cross-sectional cohort study in a university hospital from January 2002 to December 2003.Consecutive Chinese patients with acute ischemic stroke underwent CT brain, MRI brain (with MR angiography and diffusion-weighted imaging sequences), and carotid duplex. Results-In total, 251 patients were included in the analysis. Of these, 109 (43%) had concurrent stenoses. Patients who had concurrent stenoses, as compared with those without concurrent stenoses, had more symptomatic stenoses (84% versus 58%; OR, 4.0; 95% CI, 2.1 to 7.3; PϽ0.001), more concomitant perforating artery infarct, pial infarct, and borderzone infarct (14% versus 4%; OR, 3.6; 95% CI, 1.4 to 9.7; Pϭ0.007), more multiple diffusion-weighted imaging lesions (55% versus 37%; OR, 2.1; 95% CI, 1.3 to 3.4; Pϭ0.005), and more infarcts in the territory of the leptomeningeal branches of middle cerebral artery (26% versus 13%; OR, 2.2; 95% CI, 1.2 to 4.3; Pϭ0.01). In multivariate regression analysis, smoking; prior stroke; the presence of concomitant pial infarct, pial infarct, and borderzone infarcts; multiple diffusion-weighted imaging lesions; and symptomatic stenoses were significantly associated with concurrent stenoses. Among patients with concurrent stenoses, those who had tandem lesions, as compared with those who had nontandem lesions, had more perforating artery infarct and borderzone infarcts (27% versus 8%; OR, 4.3; 95% CI, 0.9 to 19.8; Pϭ0.04); more concomitant pial infarct, pial infarct, and borderzone infarcts (18% versus 0%; Pϭ0.02), and more multiple diffusion-weighted imaging lesions (65% versus 23%; OR, 6.2; 95% CI, 2.2 to 17.2; PϽ0.001). Infarcts in the territory of middle cerebral artery leptomeningeal branches and symptomatic stenoses were more common in patients with tandem lesions. Conclusions-Concomitant perforating artery infarct, pial infarct, and borderzone infarcts; multiple diffusion-weighted imaging lesions, and infarcts in the leptomeningeal branches of the middle cerebral artery were more common in patients with concurrent stenoses, especially those with tandem lesions. This study suggested that the combination of hemodynamic compromise attributable to concurrent stenoses and artery-to-artery embolization is a common stroke mechanism in these patients.
