The use of biologics in dermatology has increased rapidly. Although most are relatively safe when correctly used and monitored, there are known side effects and adverse events that occur. Selection of patients should be done on a case-by-case basis. Severity of disease, comorbidity profile, drug profile, and cost-effectiveness should be all taken into consideration while deciding to start and/or maintain one of these therapies. Dermatologists should be aware of the benefits and limitations of this class of drugs, as well as the appropriate monitoring. The authors propose a concise overview of the safety profiles of some of the biologics currently used in the dermatologic field.

Onychomycosis is a common disorder of nails caused by diverse spectrum of fungi ranging from dermatophytes to nondermatophyte molds and yeasts. Presently, oral and topical therapies are the mainstay of treatment with oral therapies yielding somewhat better results. Though various treatment options are available to treat onychomycosis, search for a convenient, cost effective agent with high and long-lasting cure rates is continuing. Currently, many new therapies for onychomycosis are under investigation which includes new formulations of azoles, improvement of existing topical treatments through addition of ungual enhancers and new drugs with better nail permeation

Survey research has been used to investigate a wide range of issues in dermatology. The proper use of survey design and analysis is critical for achieving reliable, accurate data and high impact in the medical literature. Here we describe the use of surveys from both a theoretical and practical standpoint. We provide recommendations for limiting error and producing interpretable results, followed by an outline for achieving publication. We conclude with a discussion of previous successful uses of survey studies in dermatologic literature.

Lima XT, Abuabara K, Kimball AB, Lima HC. Briakinumab.. Expert opinion on biological therapy. 2009;9(8):1107-13. doi:10.1517/14712590903092188

BACKGROUND: Psoriasis is a chronic, autoimmune, T-cell mediated, inflammatory disease. An improved understanding of the pathogenesis of the autoimmune response has led to the development of targeted biologic therapies. Briakinumab is a human monocolonal antibody that blocks the activity of the cytokines IL-12 and IL-23. Immune dysregulation has been implicated in multiple inflammatory disorders and briakinumab has been investigated for the treatment of psoriasis, rheumatoid arthritis, inflammatory bowel disease, and multiple sclerosis.

OBJECTIVES: This review focuses on briakinumab and its use in chronic plaque-type psoriasis.

METHODS: A literature review was performed, searching Medline and the clinicaltrials.gov database for all articles with the keywords ABT-874, IL-12/IL-23 and psoriasis.

CONCLUSIONS: Although limited by small sample sizes, length of follow-up, and a lack of direct comparisons with other psoriasis treatments, initial data regarding the safety and efficacy of briakinumab for the treatment of psoriasis is promising. Ongoing Phase III trials may provide additional information regarding the relative efficacy and safety of briakinumab.

Makredes M, Robinson D, Bala M, Kimball AB. The burden of autoimmune disease: a comparison of prevalence ratios in patients with psoriatic arthritis and psoriasis.. Journal of the American Academy of Dermatology. 2009;61(3):405-10. doi:10.1016/j.jaad.2009.02.015

BACKGROUND: Current research has confirmed that many inflammatory autoimmune (AI) diseases are due to derangements in multiple cytokine pathways. Some of these cytokines appear to play comparable key roles across diseases, suggesting that a similar underlying systemic inflammatory cascade could be responsible for various disease states. A recent study supports the hypothesis of a common cytokine-based pathology by showing that having one AI disease significantly increased the risk of having another AI disease. Psoriasis is an AI, manifesting as a chronic inflammatory skin condition and is clearly associated with other conditions, most obviously psoriatic arthritis (PsA).

OBJECTIVE: We sought to examine whether patients with PsA enrolled in managed health care plans carry a higher AI disease burden than patients with cutaneous psoriasis only (PsO).

METHODS: Patients 18 years or older enrolled in a health claims database were classified by two clinical subtypes: PsA and PsO. Control subjects were matched 3:1 to patients with psoriasis on age, sex, census region, and length of previous medical insurance coverage. AI disease diagnoses were identified through International Classification of Diseases, Ninth Revision codes. The association of other AI diseases with each psoriasis cohort was assessed using a prevalence ratio.

RESULTS: PsO was associated with a higher prevalence ratio for the 3 gastrointestinal diseases: Crohn disease (1.6 [confidence interval {CI} 1.4-2.0]), ulcerative colitis (1.3 [CI 1.1-1.6]), and inflammatory bowel disease (1.4 [CI 1.2-1.6]). PsA was also associated with a higher prevalence ratio for the gastrointestinal diseases: Crohn disease (2.1 [CI 1.3-3.3]), ulcerative colitis (2.0 [CI 1.3-3.1]), and inflammatory bowel disease (1.8 [CI 1.3-2.5]). Patients with PsA had an increased prevalence ratio associated with giant cell arteritis (4.8 [CI 1.5-15.7]) and pulmonary fibrosis (1.9 [CI 1.2-3.0]).

LIMITATIONS: Detection and misclassification biases may have affected these findings.

CONCLUSIONS: These findings support the hypothesis that PsA and PsO are associated with development of other AI diseases. The data suggest that evaluating patients with psoriasis for other associated disorders in a prospective manner may be important, because they may be more likely to experience the onset of another AI disease. Treatment planning for these patients could, therefore, require the medical management of more than one AI disease. Further, our data suggest that PsA and PsO may be divergent in ways previously not described that could inform future research.

Armstrong AW, Watson AJ, Makredes M, Frangos JE, Kimball AB, Kvedar JC. Text-message reminders to improve sunscreen use: a randomized, controlled trial using electronic monitoring.. Archives of dermatology. 2009;145(11):1230-6. doi:10.1001/archdermatol.2009.269

OBJECTIVE: To evaluate the effectiveness of cellular telephone text messaging as a reminder tool for improving adherence to sunscreen application.

DESIGN: We conducted a randomized, controlled trial of the effect of an electronic text-message reminder system on adherence to sunscreen application. Adherence to daily sunscreen use was evaluated using a novel electronic monitoring device.

SETTING: Participants were recruited from the general community.

PARTICIPANTS: Seventy participants constituted a volunteer sample from the general community. The inclusion criteria required participants to be 18 years or older, to own a cellular telephone with text-message features, and to know how to retrieve text messages. Intervention Half of the participants received daily text-message reminders via cellular telephone for 6 weeks, and the other half did not receive reminders. The text-message reminders consisted of 2 components: a "hook" text detailing daily local weather information and a "prompt" text reminding users to apply sunscreen. Main Outcome Measure The primary end point of the study was adherence to sunscreen application measured by the number of days participants applied sunscreen during the 6-week study period.

RESULTS: All 70 participants completed the 6-week study. There were no statistically significant differences in baseline characteristics between the 2 study groups. At the end of the study period, the 35 participants who did not receive reminders had a mean daily adherence rate of 30.0% (95% confidence interval, 23.1%-36.9%). In comparison, the 35 participants who received daily text-message reminders had a mean daily adherence rate of 56.1% (95% confidence interval, 48.1%-64.1%) (P < .001). Among the participants in the reminder group, 24 (69%) reported that they would keep using the text-message reminders after the study, and 31 (89%) reported that they would recommend the text-message reminder system to others. Subgroup analysis did not reveal any significant demographic factors that predicted adherence.

CONCLUSIONS: Despite awareness of the benefits of sunscreen, adherence is low, even in this population, for whom adherence was knowingly monitored. Short-term data demonstrate that using existing cellular telephone text-message technology offers an innovative, low-cost, and effective method of improving adherence to sunscreen application. The use of ubiquitous communications technology, such as text messaging, may have implications for large-scale public health initiatives. Trial Registration clinicaltrials.gov Identifier: NCT00535769.
