101. Pyoderma gangrenosum associated with subcorneal pustular dermatosis and IgA myeloma. (Abstract)

Pyoderma gangrenosum associated with subcorneal pustular dermatosis and IgA myeloma. We report a 57-year-old woman with a 12-year history of ulcerative pyoderma gangrenosum (PG). Five years after the onset of PG, she developed subcorneal pustular dermatosis (SPD) and biclonal IgA and IgG gammopathy. She developed PG at two bone-marrow biopsy sites, showing pathergy. Finally, she developed multiple myeloma. Although PG and SPD may occur without associated underlying malignancy, these patients

Cavitary pyoderma gangrenosum treated with local infusion of corticosteroid. Pyoderma gangrenosum (PG) is a rare inflammatory skin condition, characterized by progressive and recurrent skin ulceration, often representing a pathergy response.We report a case of spontaneous retrosternal PG that developed on the background of previous PG of the skin of the back. The patient had underlying ulcerative colitis. After failure of prednisone, minocycline, and dapsone, a novel method was instituted

eye involvement. Twelve (30%) had a positive pathergy test. Four (10%) had vascular involvement. The Lp(a) level of the patient population was 19.6+/-18.8 mg/dL. This level was higher than that of the controls, but not statistically significant. The Lp(a) levels of the four patients with vascular complications were within normal limits.Lp(a) is of interest, as it is a genetically determined parameter that was found to be high in BD patients in our study group. The levels were independent

disease, who were treated successfully using vacuum-assisted closure (VAC) for wound management. We present the advantages and disadvantages of this method, as well as illustrating the essential and known therapeutic principles.Our experience shows VAC to be an excellent and effective alternative in the treatment of therapy-resistant chronic wounds caused by vasculopathy (small vessel occlusion or vasculitis). We did not observe any pathergy or proinflammatory effects caused by VAC.2007 S. Karger AG

107. Behçet's disease-like presentation of bullous pyoderma gangrenosum associated with Crohn's disease. (Abstract)

Behçet's disease-like presentation of bullous pyoderma gangrenosum associated with Crohn's disease. A 47-year-old woman presented with a 2-month history of generalized arthralgia and a 10-day history of oral aphthous ulcers. After hospitalization, papulopustular lesions and perianal ulcerations developed. Pathergy test was positive and ophthalmological examination was normal. The presence of oral aphthous ulcers, genital ulcerations, papulopustular lesions and arthralgia, and the positive (...) pathergy test suggested the diagnosis of Behçet's disease (BD). In a few days, positive pathergy reactions and papulopustular lesions evolved into bullous lesions, which were diagnosed dermatopathologically as pyoderma gangrenosum. Two days after the presentation of papulopustular lesions, the patient experienced diarrhoea accompanied by bloody stools and mucus. Histopathological examination of biopsy specimens showed no vasculitis but revealed findings suggestive of Crohn's disease. The patient

of TNF-alpha-1031C [P = 0.018, OR = 1.83, 95% confidence interval (CI) = 1.07-3.13]. When the allele frequencies were analysed according to the clinical features, the T allele in patients with positive skin pathergy test (SPT) was significantly increased when compared with those of patients without these findings (P = 0.004, OR = 2.75, 95% CI = 1.3-5.86). To demonstrate the frequency of TNF-alpha and IFN-gamma producing cells, mononuclear cells from four representative individuals of each genotype (...) in the spontaneous IFN-gamma values between groups were not statistically significant, the stimulated IFN-gamma values were found to be significantly increased in the BD group when compared with the healthy control group (P = 0.004).Our results showed that, in the Turkish population the TNF-alpha-1031C allele is associated with susceptibility to BD. On the other hand, carrying the T allele may render patients more prone to developing a positive skin pathergy test. In addition, ELISPOT assays revealed that BD

109. Involvement of chemokines and Th1 cytokines in the pathogenesis of mucocutaneous lesions of Behçet's disease. (Abstract)

at the site of pathergy testing were studied using real-time quantitative reverse transcriptase-polymerase chain reaction.We observed important increases in the expression of interleukin-8 (IL-8) ( approximately 700-fold), monocyte chemoattractant protein 1 ( approximately 65-fold), interferon-gamma ( approximately 71-fold), and IL-12 ( approximately 69-fold) messenger RNA in BD lesions compared with normal skin. Except for IL-10 ( approximately 75-fold increase), Th2 cytokines (i.e., IL-4 and IL-13) were

112. 'Sticky' neutrophils, pathergic arthritis, and response to heparin in pyoderma gangrenosum complicating ulcerative colitis. Full Text available with Trip Pro

'Sticky' neutrophils, pathergic arthritis, and response to heparin in pyoderma gangrenosum complicating ulcerative colitis. Pyoderma gangrenosum is strongly associated with inflammatory bowel disease and exhibits pathergy, occurring at sites of previous minor trauma. A patient is presented with a 21 year history of extensive ulcerative colitis, who developed pyoderma gangrenosum and arthralgia while receiving high dose corticosteroids for active ulcerative colitis. The arthralgia exhibited (...) pathergy affecting particularly the left temporomandibular joint, which was stressed by an asymmetric bite, and the left elbow, which had been fractured many years previously. This prompted the hypothesis that neutrophils in this condition may be marginated, as a result of increased stickiness of either the neutrophil or the vascular endothelium. The introduction of heparin therapy was associated with rapid resolution of the arthralgia, pyoderma gangrenosum, and ulcerative colitis.

Response to intradermal injection of monosodium urate crystals in Behçet's syndrome. The cutaneous response to intradermal injection of monosodium urate crystals was investigated in 97 patients with Behçet's syndrome in Turkey and 14 in the United Kingdom, and in 82 healthy and 88 diseased controls. Urate crystals produced an increased erythematous response in patients compared with controls in both countries. This response was different from that of the pathergy test performed at the same

100 mg daily or placebo for three months in a double-blind manner. After three months, patients were crossed over and followed for a further three months. Patients were followed up in each visit by assessing the number, size, duration and frequency of oral and genital ulcers, other cutaneous manifestations, and systemic manifestations of the disease. A pathergy test was done on each visit. Laboratory investigations included hemoglobin concentration, white blood cell count, ESR, and C-reactive (...) protein. In dapsone-treated patients, there were significant reductions in the oral and genital ulcer parameters as well as the incidence of other cutanous and systemic manifestations. In the placebo-treated group, there were no significant changes in these parameters. The pathergy test result as well as those of other laboratory tests were all decreased in the dapsone-treated group. Although this study was a small scale study, it shows that dapsone was effective in treatment of mucocutaneous
