Long-term adalimumab efficacy in patients with moderate-to-severe hidradenitis suppurativa/acne inversa: 3-year results of a phase 3 open-label extension study.

BACKGROUND: The optimal long-term dosing strategy for adalimumab (ADA) in hidradenitis suppurativa/acne inversa (HS) was evaluated by pooling the results of the PIONEER phase 3 trials and an open-label extension (OLE) study. OBJECTIVE: To assess the response to and tolerability of long-term administration of ADA in HS. METHODS: The durations of the PIONEER I/II periods A, B, and OLE were 12, 24, and 52 or more weeks, respectively. Patients who entered the OLE and received ADA (40 mg every week continuously) and responders plus partial responders (PRRs) were evaluated. Primary efficacy assessments included measurement of HS clinical response (HiSCR), lesion counts, skin pain, and Dermatology Life Quality Index (DLQI). Treatment-emergent adverse events were assessed. RESULTS: At week 12, 52.3% of those receiving ADA weekly and 73.0% of PRRs achieved HiSCR. Achievement of HiSCR was maintained through week 168 in 52.3% of patients who received ADA weekly and 57.1% of PRRs. Sustained improvement in lesion counts, skin pain, and DLQI score were also observed. The safety profile throughout the OLE was similar to the profiles observed in the PIONEER studies. LIMITATIONS: The OLE was uncontrolled. CONCLUSION: Continuous weekly dosing with ADA, 40 mg, is a reasonable treatment option for long-term control of moderate-to-severe HS.

Legal considerations of consent and privacy in the context of clinical photography in Australian medical practice.

Clinical photography has become integral to clinical practice, especially in visually oriented specialties. Where a clinical photograph forms part of a patient's medical record, clinicians have a legal obligation to keep that photograph for several years, as determined by federal privacy legislation and various state legislation. Patients may be able to access their own clinical photographs in the context of freedom of information legislation. Consent to take clinical photographs must be informed consent, and clinicians have a legal requirement to only use the photograph for the purpose defined by that consent.

Psoriasis uncovered--measuring burden of disease impact in a survey of Australians with psoriasis.

BACKGROUND/OBJECTIVES: Internationally, the understanding of psoriasis has advanced in recent years to the point now where it is no longer considered a benign or cosmetic skin condition but a systemic, immune-mediated disease associated with significant comorbidities and considerable detriment to quality of life. The aim of this study was to gain a better understanding of the physical, psychosocial and medical burden of psoriasis on Australian adults and the impact on health status. METHODS: Two large-scale multi-centre cross-sectional studies of Australian adults with psoriasis were conducted during 2010 and 2011, with the participation of a national patient representative group (Psoriasis Australia). The studies were based on detailed questionnaires that were self-completed by individuals with psoriasis. RESULTS: A total of 362 and 330 completed surveys were received in 2010 and 2011, respectively. A significant physical, psychosocial and medical burden was reported by the respondents. It was noteworthy that patients reported actively concealing their disease from the general public (83%), work colleagues (65%), friends (58%), employers (49%), family (40%), close friends (39%) and spouse/partner (20%). The mean five-dimension European quality of life (EQ-5D) score for the 2011 cohort was 0.73, representing a significant impact on their HRQoL. The presence of comorbidities, found in three-quarters of the cohort, was associated with an even greater detriment to their HRQoL (mean score 0.64). CONCLUSIONS: Psoriasis imposes a significant psychosocial burden on the lives of patients, including a profound impact upon their personal and professional relationships, social interactions and quality of life, to a degree comparable to other serious chronic conditions. This study highlights the importance of collaboration between primary and specialist health-care providers in developing patient management strategies that address the spectrum of physical and psychological manifestations associated with psoriasis.

Analysis of patients with suspected photosensitivity referred for investigation to an Australian photodermatology clinic.

BACKGROUND: Australia's first dedicated photodermatology clinic was established at St Vincent's Hospital Melbourne in 1993. OBJECTIVE: We sought to review clinical diagnoses and results of investigations performed on patients seen at this institution. METHODS: A database was created to enable a retrospective and prospective analysis of all patients attending for evaluation of suspected photosensitivity from April 1993 to October 2000. RESULTS: A total of 513 patients were seen, 289 (56.3%) female and 224 (43.7%) male, with a mean age of 45.2 years (range: 2.6-85.9). A photosensitive disorder was diagnosed in 397 patients (77.4%), with the acquired idiopathic photodermatoses accounting for diagnoses in 215 (41.9%) of all patients seen. The most common diagnosis was polymorphous light eruption. Reduced minimal erythema doses were seen in 25.3% of all patients light tested. In those photopatch tested, 23.3% had at least 1 photocontact reaction. Allergic contact dermatitis in a photosensitive distribution was diagnosed in 7.4% of the clinic population. CONCLUSION: A large proportion of referrals to a photodermatology clinic comprise people with acquired idiopathic photodermatoses, with other common diagnoses that may mimic photosensitivity including allergic contact dermatitis, atopic dermatitis, and rosacea.

Changes of photosensitivity and action spectrum with time in solar urticaria.

BACKGROUND: Solar urticaria is a rare photosensitivity disorder characterized by the rapid onset of a pruritic, erythematous and urticarial rash following sun-exposure. The action spectrum and degree of photosensitivity have been observed to change over time in several isolated reports. METHODS: Monochromator phototesting was performed on multiple occasions on 12 patients with solar urticaria. RESULTS: Six patients demonstrated normal responses in the initial phototest. They remained normal in five patients upon subsequent testing. Seven patients demonstrated abnormal immediate responses, most frequently at UVA wavelengths. Within some individuals, variations in action spectrum and/or degree of photosensitivity were observed over the years, but not over days. CONCLUSION: Significant changes in action spectrum and degree of photosensitivity may occur over years in solar urticaria. However, changes over shorter periods of time are likely to be minor and not have clinical significance.

Thalidomide experience of a major Australian teaching hospital.

St Vincent's Hospital Melbourne cautiously prescribes thalidomide as a treatment for recalcitrant dermatoses. The guidelines used for prescribing and monitoring thalidomide for dermatological conditions at this institution are presented. Fourteen patients were treated with thalidomide (11 women, three men) over a 5-year period. The diagnoses of patients treated were actinic prurigo, prurigo nodularis, lupus erythematosus and Behçet's syndrome. A clinical improvement was noted in 10 patients (71.4%) prescribed thalidomide. Cessation of thalidomide treatment occurred in seven patients (50%) because of adverse effects. Of the patients with adverse effects, four developed abnormal nerve conduction studies and three developed intolerable adverse events (such as dizziness and vomiting). Adverse effects from thalidomide treatment are common but, through vigilant treatment planning, patient education and regular monitoring, the risk of permanent peripheral neuropathy and teratogenicity from thalidomide toxicity can be minimized.
