ABSTRACT

One of the most famous works by the Austrian symbolist painter Gustav Klimt and one of the most widely reproduced works of art worldwide, Adele Bloch-Bauer I which portrays the beautiful wife of Austrian magnate Ferdinand Bloch-Bauer. Adele was the only woman painted by Klimt on more than one occasion. Apart from the beauty and value of the painting, the daring sea of gold that surrounds Adele and the gentle intimacy with which her fragile figure is portrayed have shrouded the history of this painting in mystery. Beyond speculation as to a special bond between artist and model, observation of the painting with a keener, clinical gaze yields evidence of potential illness in the model: facial erythema which, if not produced artificially by makeup, could represent a malar rash; pallor or cyanosis of the hands; and her draped fingers, which seemingly attempt to hide a deformity. This paper seeks to provide a biographical review both of the painter, Gustav Klimt, and of the subject, Adele Bloch-Bauer; to analyse Klimt's two portrayals of her in a search for evidence of a potential intimate relationship between artist and muse and, finally, to compile clinical evidence of possible diagnoses for the Lady in Gold.

ABSTRACT

Smoking is a risk factor for thromboangiitis obliterans (TAO, Buerger's disease) and arteriosclerosis, but there are few cases of coronary heart disease (CAD)-associated Buerger's disease. A literature search for articles in English, Spanish and French published between 1966 and 2012 on patients with coronary involvement and TAO revealed 12 patients. We describe an additional case with involvement of the central nervous system, myocardium and large-diameter proximal arteries. The main clinical manifestations in these 13 cases were lower limb claudication and acute thoracic pain. The histologic findings showed thrombosis with unbroken internal elastic lamina and intimal clusters of granulocytes; coronary angiography revealed predominant involvement of the left anterior descending and right coronary artery. Treatment included coronary bypass procedures, coronary angiopiasty, smoking cessation, and anticoagulant therapy. A complete therapeutic response was observed in half the patients. This review of all published cases of TAO patients with coronary symptoms, together with our patient, demonstrates the rarity of this clinical association. Patients under age 40 with CAD but no prominent cardiovascular risk factors besides smoking should be evaluated for the presence of Buerger's disease.

ABSTRACT

BACKGROUND: Few studies have addressed the ultrastructure of vascular permeability in urticaria. OBJECTIVES: To describe the types of endothelial cell organelles involved in vascular permeability in drug-induced acute urticaria (DIAU). METHODS: Seven patients with DIAU were enrolled in the study. Biopsies of urticarial lesions and apparently normal skin were performed. The 14 collected fragmentswere processed with immunogold electron microscopy using single stains for tryptase and factor XIIIa (FXIIIa) and double immunogold labeling for both tryptase and FXIIIa. RESULTS: Some sections demonstrated mast cells in the degranulation process, in both anaphylactic and piecemeal degranulation. After double immunogold staining, 10 nm (FXIIIa) and 15 nm (tryptase) gold particles wereboth present, covering the granules in the mast cells, indicating that both tryptase and FXIIIa were localized within the granules of these cells. Interestingly, we found strong evidence of the presence of caveolae and vesico-vacuolar organelles (VVOs) in the endothelial cells of the biopsies. In addition to these findings, we were able to demonstrate the presence of tryptase and FXIIIa in the endothelial celIs, in urticarial lesions and in apparently normal skin. CONCLUSIONS: VVOs are present in the endothelial cells of post-capillary venules in DIAU. This is the first report on the expression of FXIIIa and tryptase in the cytoplasm of endothelial cells in urticaria.

ABSTRACT

The DRESS syndrome (drug reaction with eosinophilia and systemic symptoms), also known as DIHS (drug-induced hypersensitivity syndrome), presents clinically as an extensive mucocutaneous rash, accompanied by fever, lymphadenopathy, hepatitis, hematologic abnormalities with eosinophilia and atypical lymphocytes, and may involve other organs with eosinophilic infiltration, producing damage in several systems, especially kidney, heart, lungs, and pancreas. The pathogenesis is related to specific drugs (especially the aromatic anticonvulsants), altered immune response, sequential reactivation of herpes virus, and association with some HLA alleles. Glucocorticoids are the basis for the treatment of the syndrome, which may be given with intravenous immunoglobulin and, in selected cases, ganciclovir. This article reviews current concepts regarding the interaction of drugs, viruses and immune responses during this complex adverse-drug reaction.

ABSTRACT

OBJECTIVES: This study was undertaken to evaluate a possible association of adipocytokines with metabolic syndrome (MetS), inflammation and other cardiovascular risk factors in primary antiphospholipid syndrome (PAPS). METHODS: Fifty-six PAPS patients and 72 controls were included. Adiponectin, leptin, visfatin, resistin, plasminogen activator inhibitor-1 (PAI-1), lipoprotein (a), glucose, ESR, CRP, uric acid and lipid profiles were measured. The presence of MetS was determined as defined by the International Diabetes Federation (IDF), and insulin resistance was rated using the homeostasis model assessment (HOMA) index. RESULTS: Concentrations of leptin were higher [21.5 (12.9-45.7) ng/mL] in PAPS patients than in the controls [12.1 (6.9-26.8) ng/mL), p=0.001]. In PAPS patients, leptin and PAI-1 levels were positively correlated with BMI (r=0.61 and 0.29), HOMA-IR (r=0.71 and 0.28) and CRP (r=0.32 and 0.36). Adiponectin levels were negatively correlated with BMI (r=-0.28), triglycerides (r=-0.43) and HOMA-IR (r=-0.36) and positively correlated with HDL-c (r=0.37) and anti-ß2GPI IgG (r=0.31). The presence of MetS in PAPS patients was associated with higher levels of leptin (p=0.002) and PAI-1 (p=0.03) levels and lower levels of adiponectin (p=0.042). Variables that independently influenced the adiponectin concentration were the triglyceride levels (p<0.001), VLDL-c (P=0.002) and anti-ß2GPI IgG (p=0.042); the leptin levels were BMI (p<0.001), glucose (p=0.046), HOMA-IR (p<0.001) and ESR (p=0.006); and the PAI-1 levels were CRP (p=0.013) and MetS (p=0.048). CONCLUSIONS: This study provides evidence that adipocytokines may be involved in low-grade inflammation, insulin resistance and MetS in PAPS patients.

ABSTRACT

BACKGROUND: Antibodies directed against endothelial cell surface antigens have been described in many disorders and have been associated with disease activity. Since the most prominent histopathologic feature in mixed connective tissue disease (MCTD) is the widespread and unique proliferative vascular lesion, our aim was to evaluate the frequency of anti-endothelial cell antibodies (AECA) in this condition. OBJECTIVES: To evaluate the frequency of AECA in this disease and assess its clinical and laboratory associations. METHODS: Seventy-three sera from 35 patients with MCTD (Kasukawa's criteria), collected during a 7 year period, were tested for immunoglobulins G and M (IgG and IgM) AECA by cellular ELISA, using HUVEC (human umbilical vein endothelial cells). Sera from 37 patients with systemic lupus erythematosus (SLE), 22 with systemic sclerosis (SSc) and 36 sera from normal healthy individuals were used as controls. A cellular ELISA using HeLa cells was also performed as a laboratory control method. RESULTS: IgG-AECA was detected in 77% of MCTD patients, 54% of SLE patients, 36% of SSc patients and 6% of normal controls. In MCTD, IgG-AECA was associated with vasculitic manifestations, disease activity and lymphopenia, and was also a predictor of constant disease activity. Immunosuppressive drugs were shown to reduce IgG-AECA titers. Since antibodies directed to HeLa cell surface were negative, AECA was apparently unrelated to common epitopes present on epithelial cell lines. CONCLUSIONS: AECA are present in a large proportion of patients with MCTD and these antibodies decrease after immunosuppressive treatment.

ABSTRACT

Catastrophic antiphospholipid (Asherson's) syndrome (CAPS) is known to be a severe variant (1%) of antiphospholipid syndrome, with a high rate of mortality (50%). The distinguishing feature of CAPS is microvascular thromboses in the presence of antiphospholipid antibodies. Molecular mimicry between beta2-glycoprotein I and infectious agents, endothelial cell activation and reduced fibrinolysis are the most frequently described pathophysiological mechanisms. Genetic risk factors have also been implicated in the onset of CAPS, although these have not yet been identified. There have been no randomized, controlled trials evaluating the efficacy of any medication on CAPS; however, when CAPS is suspected, aggressive multimodal treatment is required. Patients who receive a combination of anticoagulation therapy, glucocorticosteroids and plasma exchange with or without intravenous immunoglobulin show the best survival rates. Herein, we review the clinical and laboratory findings, diagnostic criteria, pathophysiology, treatment and prognosis of CAPS.
