Psoriasis is a frequent skin disease, affecting 2% of the world's population. Stress, alcohol, smoking and obesity may be associated with psoriasis. A 56-year-old man with BMI 46.9 kg/m(2), hypertension and gastroesophageal reflux, had severe psoriasis for the last 39 years, without any remission on multiple treatments. Psoriatic papules and plaques were noted on his face, dorsum of hands, buttocks, knees, and elbows. He underwent open Roux-en-Y gastric bypass. At 4-month follow-up, the patient had lost 23 kg or 34.8% of excess weight, and presented complete remission of the psoriasis without medications. Bariatric surgery for positive metabolic, psychological and lifestyle consequences should be considered a treatment of psoriasis. Long-term observation is necessary.

Membranous lipodystrophy represents a peculiar type of fat necrosis that is present in patients with various types of skin disease. It is characterized by the presence of microcysts and macrocysts and is lined by amorphous eosinophilic material with a crenelated arabesque appearance. These findings have been associated with lupus erythematosus, diabetes mellitus, erythema nodosum, trauma, etc. We report a case of a 43-year-old woman who had a red to purple asymptomatic indurated plaque, approximately seven cm in diameter and on the left arm. She was a chronic hepatitis B antigen carrier and had hypertension for four years. Histopathology of the biopsied lesion showed transepidermal elimination of altered collagen and elastic fibers, as well as membranous lipodystrophy changes. There were hypertensive vascular changes including lymphohistiocytic infiltration around the vascular wall, swelling of endothelial cells, increased thickness of the vascular walls, and narrowing of the lumen. We report a case showing transepidermal elimination with membranous lipodystrophy. We carefully suggest that the secondary phenomenon of transepidermal elimination was associated with membranous lipodystrophy and degenerate connective tissues.

Psoriasis is a chronic inflammatory skin disease that is associated with an increased cardiovascular risk profile. The systemic inflammation present in psoriasis, various systemic treatments for psoriasis and an increased prevalence of unhealthy life style factors may all contribute to this unfavorable risk profile. The purpose of this article is to provide an overview of what is known about these risk factors in psoriasis, the way they influence the cardiovascular risk of psoriasis patients, and what can be done to reduce this risk. Genetic studies demonstrate that psoriasis and cardiovascular disease share common pathogenic features in which, for example inflammatory cytokines like TNF-alpha and IL-1 play an important role. The chronic inflammation in psoriasis has an unfavorable effect on the cardiovascular risk profile. Multiple cardiovascular risk factors seem to be influenced; the blood pressure, oxidative stress, dyslipidemia, endothelial cell dysfunction, homocysteine levels and blood platelet adhesion. Moreover, classic cardiovascular risk factors like smoking and obesity that have an increased prevalence among patients with psoriasis, indirectly also worsen the cardiovascular risk profile by stimulating the psoriasis activity. Systemic treatments in psoriasis reduce the cardiovascular risk by diminishing the inflammation, but it should be taken into account that most therapies also have adverse cardiovascular effects like dyslipidemia, hyperhomocysteinemia and hypertension. As a consequence preventive measures may be indicated at least during long-term treatments. Prospective research is warranted to accurately estimate the increased cardiovascular risk in psoriasis, to determine the underlying processes and to consider preventive measures according to the absolute risk of cardiovascular disease. The present overview provides data to advice health care providers to pay more attention to the cardiovascular risk profile in psoriasis patients.

The role of chronic inflammation causing metabolic and vascular disorders is increasingly recognized. It is hypothesized that proinflammatory cytokines contribute to atherogenesis, peripheral insulin resistance, and the development of hypertension and type II diabetes. Psoriasis as a chronic inflammatory skin disorder is characterized by a variety of immunologic and inflammatory changes and may similarly predispose for those disorders. The objective of this study was to elucidate the association of psoriasis with chronic vascular and metabolic disorders. We investigated a total of 581 adult patients hospitalised for plaque type psoriasis as compared to 1,044 hospital-based controls. A distinct pattern of chronic disorders was found to be significantly associated with psoriasis, including diabetes mellitus type II [odds ratio (OR)=2.48], arterial hypertension (OR = 3.27), hyperlipidemia (OR = 2.09), and coronary heart disease (OR = 1.95). The combined presence of these conditions together with obesity, known as the metabolic syndrome, was clearly more prevalent in psoriasis patients (OR = 5.29). In addition, psoriasis patients were significantly more likely to be smokers (OR = 2.96) and to have a regular or heavy consumption of alcohol (OR = 3.33 and 3.61, respectively). In conclusion, psoriasis patients appear to be at higher risk for diabetes mellitus and cardiovascular disease. This could likely be due to the effects of chronic inflammatory changes, in particular the secretion of proinflammatory cytokines. The risk of late term cardiovascular complications might support the use of systemic treatment in psoriasis.

Systemic sclerosis is an autoimmune disease characterized by fibrosis of the skin and internal organs. Raynaud's phenomenon generally precedes other disease manifestations. The distribution of skin lesions and the internal organ involvement are the basis for the classification into limited and diffuse forms of the disease. Clinically evident renal disease is observed in 10-40% of patients. The most common renal presentation is renal crisis, characterized by acute onset of renal failure and severe hypertension; some patients remain normotensive, showing microangiopathic hemolytic anemia. Renal complications due to penicillamine may occur in some patients. Finally, ANCA-associated glomerulonephritis is a rare complication of the disorder. In spite of treatment with ACE inhibitors, 20-50% of patients with renal crisis progress to end-stage renal disease. In the absence of a specific therapy, there is accumulating evidence supporting the effectiveness of prostacyclin derivatives, antifibrotic and immunosuppressive drugs. The evidence is strong that the ACE inhibitors that are used in renal crisis are disease modifying. In our series including 193 patients with systemic sclerosis, renal involvement was observed in 19 patients; 11 presented renal crisis (hypertensive in 8; normotensive in 3); 5 had chronic nephropathy; 2 developed penicillamine-induced nephrotic syndrome, and 1 ANCA-associated glomerulonephritis. Renal disease occurs in a minority of patients with systemic sclerosis, and may have a variable clinicopathological picture. As renal involvement is associated with a worse prognosis, careful monitoring of blood pressure, urine chemistry and renal function is required, particularly in patients with diffuse skin disease.

The role of pregnancy in the progression of systemic lupus erythematosus (SLE) is still poorly understood. We analysed the effect of repeated pregnancies in MRL/lpr mice, a murine model of SLE. Seven-week old female mice were used: multiparous mice underwent three consecutive pregnancies (M); age-matched virgin mice served as controls (V). Animals were harvested at 20 weeks of age. Skin lesions were characterized by hair loss and scabs in the dorsum of the neck. Virgin skins showed thickened dermis, fibrosis and mononuclear cell infiltrates, which were practically absent in M. This was accompanied by higher IFN-gamma and lower IL-10 mRNA expression levels in V compared to M skin. Plasma IFN-gamma protein levels were also upregulated in V versus M. However, survival and kidney function were dramatically reduced and accompanied by hypertension after multiple pregnancies. Kidney histology also showed markedly increased renal lesions in M. In contrast to plasma and skin levels, both IL-10 and IFN-gamma mRNA were lower in the kidneys of V versus M mice. Concluding our findings, the pathomechanisms of lupus kidney and skin disease may be regulated differently at the organ level during pregnancy. Both IFN-gamma and IL-10 may be important regulatory cytokines at the local level.

Chronic plaque psoriasis is an immune-mediated, inflammatory skin disease with a heavy burden on quality of life of patients. The disease has a chronic relapsing course and may be life long. Comorbid disorders include psoriatic arthritis, obesity, dyslipidemia, hypertension and an increased rate of cardiovascular disease. Conventional systemic treatments include methotrexate, cyclosporine and acitretin, which are associated with end organ toxicity that precludes long term therapy. Biological drugs are designed to selectively interfere with the immune mechanisms that induce psoriasis. Efalizumab is effective for skin psoriasis but not psoriatic arthritis. Anti-TNF-alpha agents (etanercept, infliximab and adalimumab) are active on both psoriasis and psoriatic arthritis. Infliximab is the most effective and rapid agent, but its safety profile may be less favourable. Moreover, efficacy can reduce over time. Etanercept is moderately active but has a better safety profile, and can be discontinued and re-used without loss of efficacy. The long term safety of all these agents has not been established.

The objective of our study was to evaluate the natural history of oral lichen planus (OLP) and other extrahepatic manifestations in the inhabitants of an area in Japan that is hyperendemic for hepatitis C virus (HCV) infection. Over 4 years, 224 adult inhabitants with HCV infection were examined for OLP by a single oral surgeon. All subjects were interviewed regarding the natural history of other extrahepatic manifestations they had developed. The antibodies to HCV (anti-HCV) and serum HCV RNA were determined. Anti-HCV were detected in sera from 224 subjects (100%); HCV RNA in 210 (93.8%). Of the 224, 88 had at least 1 oral examination for OLP during the 4-year period. In 2000, 2001, 2002 and 2003, OLP was observed in 8.5 (5/59), 14.8 (8/54), 20 (11/55) and 21.4% (12/56) of subjects, respectively. OLP prevalence increased as the subjects grew older. The incidence of OLP over the 4 years among all subjects with HCV infection was 17.0% (15/88, 2 men and 13 women). None experienced natural healing or the development of malignant transformations. Between 2000 and 2003, there was an increase in the prevalence of type 2 diabetes mellitus (DM), thyroid dysfunction, skin disease, renal disease and hypertension. Screening for extrahepatic manifestations should be conducted in patients with risk factors for HCV infection.

The psoriasis is a chronic dermatosis which is characterized by strong inflammation. Recent studies showed that the chronic inflammation plays an important part in the pathogenesis of many metabolic and vascular diseases. Moreover, the diseases mediated by lymphocytes TH1 were related to the myocardial infarction. Epidemiologic investigations showed that psoriasis is associated at the increased risk of Comorbidities and mortality per comparison to the general population. Thus, the psoriatic patients have a high prevalence of metabolic pathologies such as the diabetes, hypertension, obesity and hyperlipidemy. These concomitant affections can complicate the treatment of psoriasis. It is important that the dermatologist systematically seeks these concomitant pathologies among psoriatic patients. These data also suggest that the treatments of these patients improve not only the skin lesions, but also control the inflammation associated with the psoriasis.

Pulmonary hypertension is a common but underdiagnosed complication of systemic lupus erythematosus, which can be associated with significant morbidity and early mortality. Although often associated with anti-phospholipid antibodies, the etiology remains poorly understood. In case reports and small open trials, the anti-CD20, B-cell targeted therapeutic antibody, rituximab, has been reported to provide benefits for systemic lupus erythematosus patients with glomerulonephritis, anti-phospholipid antibody syndrome, vasculitis, arthritis, and refractory skin disease. However, the outcome of rituximab treatment of pulmonary arterial hypertension associated with systemic lupus erythematosus has not been described. We, therefore, present a case of a young systemic lupus erythematosus patient with early onset of pulmonary arterial hypertension during the disease course, refractory to multiple treatment modalities, who had significant improvement with rituximab therapy.
