A Controlled Trial of Azathioprine in Behçet's Syndrome

Cytotoxic agents have long been used in Behcets syndrome, especially for eye involvement, but their effectiveness has been uncertain. We conducted a two-year randomized, placebo-controlled, double-blind trial of azathioprine (2.5 mg per kilogram of body weight per day) in Turkish men with Behcets syndrome without eye disease (group 1; n = 25) or with eye disease (group 2; n = 48). Corticosteroid treatment remained available to all the patients. All six patients withdrawn from the study because of severe eye disease were receiving placebo (P less than 0.001). Azathioprine was superior to placebo in the prevention of new eye disease in group 1 (1 vs. 8 patients; P less than 0.01) and in group 2 among the 14 patients who at entry had disease in only one eye (P less than 0.001). There were fewer episodes of hypopyon uveitis (1 vs. 15; P less than 0.001) among the group 2 patients who took azathioprine. The patients taking azathioprine also had less frequent oral ulcers, genital ulcers, and arthritis. There were no serious side effects attributable to azathioprine. We conclude that azathioprine is effective in controlling the progression of Behcets syndrome, especially its most serious manifestation, eye disease.

Recommendations for pimecrolimus 1% cream in the treatment of mild-to-moderate atopic dermatitis: from medical needs to a new treatment algorithm

Pimecrolimus 1% cream is an effective, non-corticosteroid, topical anti-inflammatory treatment for atopic dermatitis (AD). The aim of this article was to review published clinical data that have examined how pimecrolimus can address the medical needs of AD patients. Clinical studies have demonstrated that early treatment with pimecrolimus decreases the progression to disease flares, rapidly improves pruritus and significantly enhances quality of life. Patients find the formulation easy to apply, which may result in improved adherence with the treatment regimen. Pimecrolimus, in contrast to topical corticosteroids (TCSs), does not induce skin atrophy or epidermal barrier dysfunction and is highly effective for the treatment of AD in sensitive skin areas. Furthermore, pimecrolimus reduces the incidence of skin infections compared with TCSs and is not associated with other TCS-related side effects such as striae, telangiectasia and hypothalamic-pituitary-adrenal axis suppression. An additional benefit of pimecrolimus is its substantial steroid sparing effect. On the basis of these data, a new treatment algorithm for patients with mild-to-moderate AD is proposed in which pimecrolimus is recommended as a first line therapy for patients with established mild AD at the first signs and symptoms of disease. Pimecrolimus is also recommended for mild-to-moderate AD after initial treatment with a TCS. After resolution of lesions, maintenance treatment with pimecrolimus may effectively prevent subsequent disease flares. In conclusion, the clinical profile of pimecrolimus suggests that it may be considered the drug of choice for the treatment of mild-to-moderate AD in children as well as adults and particularly in sensitive skin areas.

Evaluation of body composition parameters in patients with psoriasis

Body composition parameters, such as weight, body mass index (BMI), and visceral fat rating, have been found to be associated with psoriasis. However, the associations of these parameters with psoriasis have not been demonstrated clearly.

A retrospective analysis of patients with pemphigus vulgaris associated with pregnancy

SIR, Interferon alfa (IFN-a) therapy is highly effective in patients with chronic myelogenous leukaemia and other malignant diseases. Most side-effects, such as chills, malaise, myalgia and fatigue, are transient and tend to disappear with ongoing therapy, while others, such as anorexia, neurological and mood disorders, are dose-related and need dose adjustment or withdrawal of IFN-a. Induction of immunemediated disease, including thyroid disease, rheumatoid arthritis, systemic lupus erythematosus, vasculitis, thrombocytopenia, autoimmune haemolytic anaemia, and insulin-dependent diabetes mellitus, has also been described. Moreover, other immunological entities, such as myasthenia gravis, vitiligo, lichen planus, Henoch–Schönlein purpura and Sjögren syndrome, have been reported after IFN-a therapy for chronic viral hepatitis or multiple sclerosis (MS). Here, we report on the first case of systemic sclerosis (SSc) developing after therapy with IFN-a for chronic myelogenous leukaemia. In October 1998, a 52-year-old-woman without a personal or a familiar history of autoimmune disease, was diagnosed as having chronic myelogenous leukaemia, with a karyotype 46,XX,t(9;22), bcr ⁄ abl positive in all the metaphases. She was given hydroxyurea 20 mg kg day for 2 months and then IFN-a 2a to a maximum daily dose of 10 · 10 U. In June 1999, cytogenic evaluation showed a normalization of the karyotype in up to 33% of metaphases. Meanwhile, treatment was reduced to 6 · 10 U day for the appraisal of arthralgias, ataxia and depression. In June 2000 a further evaluation revealed the loss of efficacy of therapy (Ph chromosome positive in all the analysable metaphases). In the same period, the patient experienced fever, dyspnoea and oedema of the extremities. Laboratory findings were normal, except for an increased erythrocyte sedimentation rate (ESR, 50 mm in the first hour). Chest X-ray and computed tomography (CT) of the lung demonstrated the presence of pulmonary vascular congestion. Cardiac function, evaluated by electrocardiogram and Doppler echocardiography, was normal. The possible diagnosis of congestive heart failure was discarded and the patient’s symptoms were ascribed to a leak capillary syndrome secondary to interferon therapy; interferon therapy was interrupted. Peripheral oedema and respiratory symptoms improved on treatment with diuretics. Nevertheless, 3 months later, in November 2000 she experienced dyspnoea, oedema of both the upper and lower limbs and progressive skin thickening of the hands and wrists. A further echocardiographic evaluation revealed a normal ejection fraction (70%) and minimal tricuspid regurgitation with increased pulmonary artery pressure (34 mmHg). CT of the chest showed a picture of diffuse parenchymal and interstitial fibrosis with multiple areas of ground-glass attenuation. Pulmonary function tests demonstrated the presence of reduced volumes with an impaired diffusion capacity for carbon monoxide (DLCO, 46% predicted). Oesophagogastroduodenoscopy showed a total absence of peristalsis. Laboratory examination indicated: elevated ESR (80 mm in the first hour), impaired renal function (creatinine, 1Æ8 mg dL) with mild proteinuria (72 mg 24 h) and positive antisclero-70 antibodies. Her complete major histocompatibility phenotype was HLA-DRB1*11; 07, DQA*05;0201, DQB*03;02, A28, A24, B35, B13, Bw4, Bw6, Cw4. Capillaroscopy findings were consistent with scleroderma, showing multiple microhaemorrhages, dilation, distortion and rarefaction of capillaries. No skin biopsy was performed. A diagnosis of localized SSc was put forward, according to LeRoy et al. The patient was given loop diuretics, cyclophosphamide 100 mg day, prostanoids (iloprost, 2 ng kg min for 8 h for five consecutive days and then thrice monthly), steroids (methylprednisolone 750 mg intravenously for 3 days and then prednisone 25 mg day). In the following months the patient’s clinical condition improved, scleroedema decreased, the skin thickening partially receded and the signs of alveolitis were no longer detectable at a further CT evaluation of the lung (October 2001). Therapy has been gradually tapered and the patient is now receiving cyclophosphamide 50 mg day, prednisone 12Æ5 mg day, iloprost 2 ng kg min for 8 h every 3 weeks and hydroxyurea 10 mg kg on every alternate day. The patient’s main clinical and laboratory findings, before and after 10 months of therapy, are summarized in Table 1. Several authors showed that IFN-a therapy for malignancies, chronic viral hepatitis or MS may trigger the formation of autoantibodies directed toward various substrates, such as thyroid, platelets, erythrocytes, pancreas, parietal cells and nuclei. Their occurrence is sometimes, but not necessarily, coupled with the onset or the exacerbation of autoimmune diseases. In most cases endocrine disorders are described, but rheumatic and collagen–vascular diseases have been observed as well. Nevertheless, to date, no reports of SSc after interferon therapy have been made. However, Wandl et al. noticed that patients who develop antinuclear antibodies may experience Raynaud’s phenomenon, one of the diagnostic findings in SSc. Moreover, Black et al. pointed out that IFN-a therapy in the treatment of scleroderma may be deleterious, exacerbating life-threatening symptoms and precipitating the lung deterioration. As far as our patient is concerned, the laboratory findings, typical vascular alterations and ⁄ or clinical signs of autoimmunity are ascribable to interferon therapy. The patient had neither a personal nor a familiar history of autoimmunity, and a clear temporal relation between IFN-a administration and the occurrence of initial symptoms can be seen. Besides, she did receive IFN-a continuously for approximately 2 years. Fattovich et al. indeed noticed that de novo immuneBritish Journal of Dermatology 2002; 147: 385–410.

An alternative treatment modality for cellulite: LPG endermologie

Abstract Background: LPG endermologie is a worldwide FDA-approved massage system used in the treatment of cellulite. Objective: The aim of this study is to evaluate safety, efficacy, and the slimming potential of LPG endermologie. Material and methods: A total of 118 women (mean age, 34.59 ± 8.02 years) were enrolled in this study. The LPG treatment sessions were performed twice weekly and continued for at least 15 sessions. The outcome was clinically evaluated using digital photography for cellulite grade assessment while perimetric measurements for eight body sites were performed. The evaluation also included measurements of body weight and body fat percentage (BFP). Results: One hundred and seventeen patients (99%) showed loss in body circumference measurements. A mean body circumference reduction of 2.9 ± 1.6 cm was obtained per site for all patients. There was a mean body circumference loss which was statically significant with p < 0.001. Weight loss was detected in one hundred and three patients (87%). The mean body weight loss was 2.717 ± 1.938 kg for all patients. One hundred and ten subjects (93%) also showed decreases in BFP. The questionnaire indicated high satisfaction in 81 (69%) patients. Conclusion: LPG endermologie is a well-tolerated and effective alternative treatment modality for slimming and body contouring.

Evaluation of Advanced Oxidation Protein Products, Prooxidant-Antioxidant Balance, and Total Antioxidant Capacity in Untreated Vitiligo Patients

Background Vitiligo is a chronic, common disease of unknown etiology, and oxidative stress is suggested to have a role in its etiopathogenesis. Objective Advanced oxidation protein products (AOPPs), prooxidant-antioxidant balance (PAB), and ferric-reducing antioxidant power (FRAP) were evaluated regarding their role in the pathogenesis of vitiligo as well as their relationship with clinical presentation and disease severity, and these parameters were compared with those of healthy controls. Methods The study included 53 patients with vitiligo and 20 healthy volunteers as the control group. AOPP level, PAB, and FRAP were determined by colorimetric methods. Results PAB and FRAP level were significantly higher in patients with vitiligo than in healthy controls (p<0.001). The AOPP levels in vitiligo patients were not statistically significantly higher than those in healthy controls. The Vitiligo Area Scoring Index positively correlated with disease duration (rs: 0.531, p<0.001). Conclusion To the best of our knowledge, this is the first report of AOPP and PAB status in vitiligo. PAB may be used as an indicator for oxidative stress in the etiopathogenesis of vitiligo. Our results show that these parameters may play a major role in the melanocyte damage observed in vitiligo. Further studies are required to confirm the mechanisms underlying this effect.

Helicobacter pylori infection and skin disorders.

Helicobacter pylori is a Gram-negative bacterium that has been linked to peptic ulcer disease, gastric lymphoma, and gastric carcinoma. Apart from its well-demonstrated role in gastroduodenal diseases, some authors have suggested a potential role of Helicobacter pylori infection in several extra-intestinal pathologies including haematological, cardiovascular, neurological, metabolic, autoimmune, and dermatological diseases. Some studies suggest an association between Helicobacter pylori infection and skin diseases such as chronic idiopathic urticaria and rosacea. There have also been few case reports documenting association between Helicobacter pylori and psoriasis vulgaris, Behçets disease, alopecia areata, Henoch-Schönlein purpura, and Sweets syndrome. However, more systematic studies are required to clarify the proposed association between Helicobacter pylori and skin diseases; most of the studies do not show relevant relationships of these diseases with Helicobacter pylori infections. This review discusses skin diseases that are believed to be associated with Helicobacter pylori.

Paraneoplastic pemphigus associated with fludarabine use.

Paraneoplastic pemphigus is a severe mucocutaneous disease associated with B-cell lymphoproliferative disorders. A 51-yr-old man presented to the oncology clinic with mucocutaneous skin lesions after six cycles of fludarabine for non-Hodgkin’s lymphoma. A punch biopsy from the skin showed suprabasal acantholysis and blister formation in the epidermis and upper dermis. Direct immunofluorescence demonstrated intercellular IgG deposition in all epidermal layers and complement (C3) at the basement membrane. The indirect immunofluorescence on rat bladder showed intercellular binding of IgG. These findings were consistent with paraneoplastic pemphigus associated with fludarabine use. The temporal association between fludarabine use and paraneoplastic pemphigus suggests there is an etiopathological link between these two entities.

A case of solitary angiokeratoma successfully treated with a 1064-nm long-pulsed Nd:YAG laser

Abstract Angiokeratomas are vascular malformations that are clinically or histologically verrucous, with superficial vessels just beneath the epidermis. Solitary angiokeratomas occur most commonly as a small, warty, black papule on the lower extremities. Various therapeutic methods, including laser, electrocoagulation, excision, and cryotherapy, may be used for their treatment. A 13-year-old girl presented to the laser clinic for the treatment of her lesions that were present for two months. A 1064-nm long-pulsed Nd:YAG (yttrium aluminium garnet) laser was used to treat the patients lesions. We performed two laser treatment sessions at a 4-week interval. We saw the patient 1 month after the last treatment session and obtained successful cosmetically acceptable results. No recurrence was observed over a follow-up period of 3 months. Long-pulsed Nd:YAG laser is more effective for the treatment of hyperkeratotic angiokeratomas due to deeper skin penetration of laser. Long-pulsed Nd:YAG laser is an effective and safe therapeutic option for the treatment of solitary angiokeratomas.

Evaluation of Effectiveness of Cryotherapy on the Treatment of Cutaneous Kaposi's Sarcoma

OBJECTIVE Kaposis sarcoma (KS) is a vascular tumor that affects the skin and other organs. Several therapeutic options are available, but the optimal therapy is unclear. The aim of this study was to determine the effectiveness and safety of cryotherapy in the treatment of KS. MATERIALS AND METHODS Thirty patients were evaluated. Cryotherapy was applied using liquid nitrogen. Each treatment consisted of two freeze–thaw cycles, with freezing times ranging from 15 to 40 seconds per cycle. RESULTS One hundred twenty‐five lesions were treated in an average of 3.2 sessions. Complete response was observed in 19 (63%) of the 30 patients after cryotherapy treatment with no recurrence. The subjects tolerated cryotherapy well. Blistering occurred frequently, but local pain was limited. There were no secondary infections. CONCLUSION Liquid nitrogen cryotherapy is safe and cost‐efficient and can be readily adopted as an effective primary therapy for cutaneous KS lesions that respond slowly or show incomplete cosmetic improvement after systemic therapies.
