Persisting Ulcerating Lesions After Cyclosporine Therapy for Erosions Found in Flexural Sites.

In February 2012, a patient with a 15-year history of painful, pruritic eruptions presented with a severe exacerbation that had lasted for the previous week. The patient also reported severe headaches, a fever of 38.9°C (102.1°F), a cough, and diarrhea, which had now resolved. Physical examination showed erythematous macerated patches with erosions in the left submammary region, bilateral axillae, and vaginal area (Figure 1), and greasy scale covering the scalp. Despite lessening of the lesions in the submammary region and abdomen with the administration of minocycline 100 mg twice per day and cyclosporine 100 mg three times per day, the patient continued to complain of persistent painful ulcerations in the labia majora and perianal area (Figure 2). The patient was started on acyclovir 400 mg three times per day for 10 days for positive herpes simplex viral culture and ampicillin for Proteus infection of the area.

Incidence of Pulmonary Arterial Hypertension in Patients with Psoriasis: A Retrospective Cohort Study.

CONTEXT: Inflammatory signaling may play an important role in the pathogenesis of pulmonary arterial hypertension (PAH). OBJECTIVE: To assess the incidence of PAH in patients with mild and severe psoriasis compared with their respective controls. DESIGN: From January 2004 to November 2012, we performed a retrospective cohort study of patients with psoriasis in the Kaiser Permanente Southern California Health Plan. Patients with an International Classification of Diseases, Ninth Revision Clinical Modification diagnostic code for psoriasis (696.1) or psoriatic arthritis (696.0) without a prior diagnosis of primary PAH (416.0) or secondary PAH (416.8) were eligible for inclusion. Patients who had never received a diagnosis of psoriasis were frequency-matched by age, sex, and race to form the control cohorts. MAIN OUTCOME MEASURES: Incidence of PAH in patients with psoriasis compared with matched controls. RESULTS: There were 10,115 patients with mild psoriasis, 3821 with severe psoriasis, and 69,360 matched controls. On multivariable analysis, there was a significantly increased risk of PAH developing in the severe psoriasis cohort vs their controls (hazard ratio = 1.46, 95% confidence interval = 1.09-1.94). CONCLUSION: The systemic inflammatory process underlying psoriasis may be a cause for an increased risk of PAH, but there are numerous secondary causes of PAH, some of which were not accounted for in our study. Further prospective, randomized controlled trials are necessary to establish psoriasis as a risk factor for PAH.

Trends in Type of Original Psoriasis Publications by Decade, 1960 to 2010.

CONTEXT: Research investigating psoriasis has spanned decades, and as our understanding of the disease has evolved, the focus of publications has changed. OBJECTIVE: We sought to characterize the trends in original psoriasis-related research from 1960 to 2010 chronologically by decade. METHODS: A literature review was performed using the keyword psoriasis in the MEDLINE database. All original psoriasis-related articles published at the beginning of each decade were searched and categorized by study type and topic. MAIN OUTCOME MEASURE: Number of articles per topic. RESULTS: A total of 869 original psoriasis-related articles were found. The number of publications increased 18 fold over 5 decades. The immunology and pathogenesis of psoriasis was the most frequently researched topic (36%), and retrospective studies were the most common study type (37%). Recent highly published topics included biologic therapy, genetics, and psoriasis-associated cardiovascular disease. CONCLUSION: Original psoriasis-related publications have grown substantially since 1960. Basic science research into the immunology and pathogenesis has been and continues to be the mainstay of psoriasis research. Recent research trends suggest the focus has expanded to topics such as psoriasis-associated cardiovascular disease, genetics, and biologic therapy.

Melanoma in patients with chronic lymphocytic leukemia and non-Hodgkin lymphoma.

BACKGROUND: The relationship between melanoma and chronic lymphocytic leukemia (CLL) or non-Hodgkin lymphoma (NHL) has been minimally investigated. OBJECTIVE: The objective of this study was to examine the incidence of melanoma in patients with a history of CLL or NHL, and their associated mortality. METHODS: Cohorts of Kaiser Permanente Southern California members with a history of CLL and NHL were identified. Age-adjusted incidence density rates of melanoma among patients with CLL or NHL were compared with rates of melanoma among the general population of Kaiser Permanente Southern California patients. The mortality of patients with melanoma was examined using Cox proportional hazards modeling. RESULTS: The age-adjusted incidence rate per 100,000 person-years for melanoma among patients with either CLL or NHL was 107 (95% confidence interval 84.4-129.6) versus 25.9 among the general population (95% confidence interval 84.4-129.6, P < .001). Patients with melanoma and a history of CLL or NHL had 2.46 greater odds of death compared with those without CLL or NHL (95% confidence interval 1.77-3.41). LIMITATIONS: This study was retrospective in nature; the International Classification of Diseases, Ninth Revision codes used may contain diagnostic errors; and only overall survival was used in our analysis. CONCLUSIONS: Patients with a history of CLL or NHL have a higher incidence of melanoma. Patients with CLL or NHL who are subsequently given the diagnosis of melanoma have a higher mortality than patients with melanoma without a preceding diagnosis of CLL.

Evidence for supplemental treatments in androgenetic alopecia.

Currently, topical minoxidil and finasteride are the only treatments that have been FDA approved for the treatment of female pattern hair loss and androgenetic alopecia. Given the incomplete efficacy and sife effect profile of these medications, some patients utilize alternative treatments to help improve this condition. In this review, we illustrate the scientific evidence underlying the efficacy of these alternative approaches, including biotin, caffeine, melatonin, a marine extract, and zinc.

Finasteride associated melasma in a Caucasian male.

Melasma is an acquired hypermelanosis that typically affects sun-exposed areas on the face and presents as symmetric brownish macules and patches. It is most commonly reported in women and thought to be related to the effects of estrogen and progesterone on melanocytes. Since the advent of finasteride 1mg daily tablets for the treatment of androgenic alopecia, we have noticed an increase in the number of men presenting with melasma. Here we present one of those cases. We hypothesize this could be related to the effects of finasteride on estrogen and progesterone concentrations in the skin.

Bariatric surgery and psoriasis.

Obesity is associated with psoriasis and poses a significant obstacle to psoriasis management. Bariatric surgery is an effective procedure for weight loss, and some reports suggest that it may improve psoriasis. However, more evidence is needed before definitive conclusions can be drawn. Bariatric surgery procedures, in particular the Roux-en-Y gastric bypass, may one day be a viable option for obese patients with refractory psoriasis.

Aspirin use and melanoma risk: a review of the literature.

In view of the increasing incidence of melanoma, it is critical to find effective preventive approaches. Contradictory evidence has been reported with regard to the possible association of aspirin use and the risk of melanoma. We review these studies and seek to elucidate the mechanism by which aspirin may produce a chemoprotective effect against melanoma.

Effect of treating psoriasis on cardiovascular co-morbidities: focus on TNF inhibitors.

Psoriasis patients are at increased risk for cardiovascular disease. Literature on rheumatoid arthritis has shown the association of treatment with tumor necrosis factor (TNF) inhibitors and improvement of cardiovascular disease. Recent literature has also shown similar findings in psoriasis patients. We present a review of the literature on the effect of TNF inhibitors for psoriasis treatment on cardiovascular disease, cardiovascular biomarkers, and insulin resistance. We conclude that TNF inhibitors may be especially beneficial in preventing myocardial infarction, to a degree greater than methotrexate, especially in the Caucasian population. The effects of TNF inhibitors in altering insulin sensitivity or preventing new onset diabetes have been contradictory. Case reports of both hyperglycemia and hypoglycemia developing in patients under TNF inhibitor treatment teach us to warn patients about these side effects. More robust clinical studies are needed to evaluate the true effect of TNF inhibitors in diabetic psoriasis patients. More studies are also needed to assess the effect of TNF inhibitors on hypertension, dyslipidemia, and stroke.

Partial reversal of androgenetic alopecia with methotrexate therapy for psoriasis.

We report the case of a 64-year-old man with androgenetic alopecia who was started on methotrexate therapy for treatment of psoriasis after traditional modalities failed. Following treatment with methotrexate, he noted hair regrowth on the scalp. We propose that methotrexate may inhibit gonadal steroidogenesis, therefore leading to lower testosterone levels, or may increase testosterone aromatization at the hair follicles. These mechanisms may account for the hair growth observed in our patient, which indicates that partial reversal of androgenetic alopecia may be a side effect of methotrexate therapy.

Combination therapy with tumor necrosis factor inhibitors in psoriasis treatment.

Psoriasis is a systemic disease that affects approximately 2% of the US population. Traditional treatment modalities include phototherapy, topical therapy, methotrexate, cyclosporine, and retinoids. Three tumor necrosis factor (TNF) inhibitors have been approved by the US Food and Drug Administration for the treatment of plaque psoriasis: etanercept, infliximab, and adalimumab. The combination of TNF inhibitors with phototherapy and topical and systemic agents may be effective in treating patients who are recalcitrant to monotherapy. We examine clinical trials that evaluated the efficacy and safety of combination treatments with TNF inhibitors. This review elucidates that combination therapy is both effective and well tolerated among patients with refractory psoriasis. Furthermore, combination therapy may allow for reduction of required treatment doses, thereby decreasing the potential for toxicity. It is important to note, however, that the studies reviewed here are limited in the long-term follow-up of patients. We conclude that dermatologists can safely and effectively incorporate combination therapy with TNF inhibitors in the treatment of patients with recalcitrant psoriasis.

Infliximab-induced psoriasis in treatment of Crohn's disease-associated ankylosing spondylitis: case report and review of 142 cases.

TNF-alpha inhibitors are used to treat numerous inflammatory conditions including rheumatoid arthritis and inflammatory bowel disease. Recent reports have illustrated the paradoxical development of psoriasis with TNF-alpha inhibitor therapy. We present here a review of 142 cases of new-onset psoriasis with infliximab, adalimumab, and etanercept therapy. This review illustrates the diverse conditions responsible for TNF-alpha-inhibitor induced psoriasis, the variable time prior to psoriasis development, and the most predominant forms of psoriasis. An analysis of the various therapeutic regimens applied may help provide guidelines for patient management.

The efficacy of ustekinumab in psoriasis.

Psoriasis is an immune-mediated cutaneous disease affecting 2% of the worldwide population. While topical therapy, phototherapy, oral systemic therapy, and biologic agents have been used, the treatment of psoriasis still remains a challenge. Ustekinumab is a biologic therapy that provides a novel avenue for management by blocking interleukin-12/23. The purpose of this article is to review the mechanism of action of ustekinumab and its efficacy in psoriatic patients. The use of ustekinumab in other immune-mediated diseases is also discussed. It is our goal to provide dermatologists with the knowledge to enable them to incorporate ustekinumab into their practice.

The safety of ustekinumab in psoriasis.

Ustekinumab is effective in the treatment of a variety of autoimmune conditions including psoriasis. As a relatively new therapeutic agent, its long-term effects are still under investigation. Short-term studies, however, have revealed ustekinumab to be generally well tolerated and safe. This article provides a comprehensive review of the pharmacokinetics of ustekinumab, its safety profile, adverse effects, and use in pregnancy. The effect of diabetes and prior immunosuppressant therapy is also addressed.

Perspectives of people in Mali toward genetically-modified mosquitoes for malaria control.

BACKGROUND: Genetically-modified (GM) mosquitoes have been proposed as part of an integrated vector control strategy for malaria control. Public acceptance is essential prior to field trials, particularly since mosquitoes are a vector of human disease and genetically modified organisms (GMOs) face strong scepticism in developed and developing nations. Despite this, in sub-Saharan Africa, where the GM mosquito effort is primarily directed, very little data is available on perspectives to GMOs. Here, results are presented of a qualitative survey of public attitudes to GM mosquitoes for malaria control in rural and urban areas of Mali, West Africa between the months of October 2008 and June 2009. METHODS: The sample consisted of 80 individuals - 30 living in rural communities, 30 living in urban suburbs of Bamako, and 20 Western-trained and traditional health professionals working in Bamako and Bandiagara. Questions were asked about the cause of malaria, heredity and selective breeding. This led to questions about genetic alterations, and acceptable conditions for a release of pest-resistant GM corn and malaria-refractory GM mosquitoes. Finally, participants were asked about the decision-making process in their community. Interviews were transcribed and responses were categorized according to general themes. RESULTS: Most participants cited mosquitoes as one of several causes of malaria. The concept of the gene was not widely understood; however selective breeding was understood, allowing limited communication of the concept of genetic modification. Participants were open to a release of pest-resistant GM corn, often wanting to conduct a trial themselves. The concept of a trial was reapplied to GM mosquitoes, although less frequently. Participants wanted to see evidence that GM mosquitoes can reduce malaria prevalence without negative consequences for human health and the environment. For several participants, a mosquito control programme was preferred; however a transgenic release that satisfied certain requirements was usually acceptable. CONCLUSIONS: Although there were some dissenters, the majority of participants were pragmatic towards a release of GM mosquitoes. An array of social and cultural issues associated with malaria, mosquitoes and genetic engineering became apparent. If these can be successfully addressed, then social acceptance among the populations surveyed seems promising.
