Increased carotid atherosclerosis and carotid artery stiffness according to the disease duration and activity in patients with systemic lupus erythematosus / 고신대학교의과대학학술지

OBJECTIVE: The link among carotid intima-media thickness (IMT), vascular elastic property and the disease activity of systemic lupus erythematosus (SLE) is not well defined. We investigated the association between carotid atherosclerosis, elastic properties of the carotid arterial wall and clinical parameters of SLE. METHODS: Fifty-one SLE patients and fifty healthy controls were included. Peak systolic global circumferential and posterior radial strains of carotid artery were measured to assess the elastic properties. Beta stiffness index was used as conventional method for the distensibility of the carotid artery. Information concerning SLE duration, cumulative dose of steroids and/or immunosuppressive drug intake was recorded, and SLE activity was assessed by SLE disease activity index (SLEDAI) score. RESULTS: Carotid plaques were more common in SLE patients. SLE patients with plaques were older and showed the increased mean IMT, high sensitivity C-reactive protein (hs CRP), IgG anti-cardiolipin antibody (aCL), and longer disease duration compared with those without plaques. Peak systolic global circumferential and posterior radial strain as well beta stiffness index were significantly lower in SLE group. Age, disease duration, hsCRP, IgG aCL showed significant correlations with mean IMT and parameters of carotid elastic property (all P's<0.05). CONCLUSIONS: Carotid atherosclerosis was more common in SLE patients, and carotid arterial stiffness had significant correlation with disease duration, hsCRP and IgG aCL level. Speckle tracking strain imaging is a comparative method for the assessment of elastic properties of carotid artery of SLE patients.

A Case of Persistent Apical Ballooning in a Patient with SLE

Apical ballooning syndrome (ABS), also referred to as stress cardiomyopathy, is characterized by acute left ventricular dysfunction following a stressful situation. Diagnosis of ABS is made in the following scenarios: transient hypokinesia or dyskinesia of the left ventricular segment, absence of obstructive coronary disease, new electrocardiogram abnormalities, absence of recent significant head trauma, pheochromocytoma, myocarditis, and hypertrophic cardiomyopathy. Prognosis is usually favorable since the wall motion abnormality returns to normal within days, and certainly within the first month. We encountered a case of SLE with apical ballooning on echocardiography in a 44-year-old woman. She was suffering from severe left ventricular dysfunction that has persisted on 5 year follow-up echocardiography. We report this case along with a review of the relevant literature.

A Case of Infliximab-induced Psoriasis in Treatment of Ankylosing Spondylitis

Infliximab, which is indicated for refractory rheumatoid arthritis (RA), ankylosing spondylitis (AS) and Crohn's disease, has cutaneous adverse events including skin rash, urticaria, pruritus, and lupus-like eruption. Psoriasis induced by infliximab is very rare. In Korea, it is infrequently reported in Crohn's disease or RA and never reported in AS. We encountered a case of psoriasis induced by infliximab treatment for AS, and report here on this case along with a review of the relevant literature.

A Case of Diffuse Idiopathic Skeletal Hyperostosis Presenting with Dysphagia Secondary to Cervical Osteophyte and Restrictive Ventilatory Impairment / 대한내과학회지

Diffuse idiopathic skeletal hyperostosis (DISH) is a condition characterized by the calcification and ossification of soft tissue, and can lead to severe cervical kyphosis, presenting with a spectrum of physical complaints including dysphagia, hoarseness, stridor, aspiration pneumonia, and dyspnea due to airway compromise. Restrictive ventilatory impairment is very rare. We encountered a 73-year-old man with DISH presenting with progressive dysphagia and dyspnea over a few months. The symptoms were evaluated with a video fluoroscopy swallowing study and pulmonary function tests (PFT). The PFT revealed restrictive ventilatory impairment. A neck magnetic resonance imaging (MRI) study showed anterior cervical osteophytes causing upper airway compromise and compression of the esophagus. Osteophytes were removed surgically and the patient improved clinically. Here, we describe the case with a literature review.

Microvascular Findings in Patients with Rheumatoid Arthritis: Assessed, Using Fundus Photography and Fluorescein Angiography

OBJECTIVE: Although a series of trials support that rheumatoid arthritis (RA) is associated with increased atherosclerosis, the link between microvascular structural changes and the disease activity of RA has not been clarified. We measured changes in the retinal microvasculature using fundus fluorescein angiography (FAG) and investigated the association between the retinal vasculature and clinical parameters of RA. METHODS: Seventy-five RA patients and sixty healthy control were included. Morphometric and quantitative features in the capillary images including retinal vascular signs and vessel diameters were measured with fundus photography and FAG. RA activity was assessed based on high sensitivity C-reactive protein (hsCRP), disease activity score with 28 joints (DAS 28), and health assessment questionnaire (HAQ). RESULTS: Central retinal arteriolar equivalents (CRAE) was 118.1+/-31.3 microm in RA patients and 123.8+/-19.9 microm in control subjects, showing the tendency of retinal arteriolar narrowing in patients with RA but without statistical significance. The mean central retinal venular equivalents (CRVE) was 162.4+/-26.4 microm which was significantly higher than that of control group (144.1+/-23.1 microm, p<0.001). The prevalence of AVN was 34.7%, and significantly higher in RA group. Among retinal findings, the presence of early pinpoint hyperfluorescence and areas of delayed choroidal perfusion correlated with hsCRP. Age, disease duration, DAS 28, HAQ, and rheumatoid factor (RF) had no effect on CRAE and CRVE. In multivariate analysis, only hsCRP was found to be associated with wider venular caliber. CONCLUSION: Retinal venular widening was more common in RA patients. Retinal venular diameter had significant correlation with disease activity of RA. Retinal imaging is a comparative method for the assessment of microvascular findings of RA patients.
