The development of an Excel® spreadsheet to document disease activity in autoimmune bullous disease

We have developed a specialised Excel® spreadsheet which records a panel of clinical variables for patients presenting to specialised bullous clinics at our institution. The spreadsheet incorporates scores for the two disease specific instruments for autoimmune bullous disease; the Autoimmune Bullous Skin Disorder Intensity Score (ABSIS) and the Pemphigus Disease Area Index (PDAI), as well as medication doses, and quality of life (QOL) scores. The spreadsheet has automated arithmetic functions for tallying scores, explanatory pop-ups and restrictions on data values to prevent the inadvertent input of invalid data. The major strength of the spreadsheet is that using the graph function, one can instantly appreciated how the disease trajectory of a patient has evolved across a range of parameters (such as disease activity, QOL and the need for immunosuppression) through the visual depiction of their clinical course. The spreadsheet built by our group is practical for routine clinical use and is a useful tool for longitudinal monitoring of disease activity in bullous patients.</p

Dupilumab-associated ocular surface disease : an interdisciplinary decision framework for prescribers in the Australian setting

Background/Objectives: Dupilumab-associated ocular surface disease (DAOSD) is of particular relevance in patients with atopic dermatitis (AD). Guidance on DAOSD assessment and management in the Australian setting is needed to reduce its impact and minimise disruption to treatment. Methods: A systematic review of the literature was undertaken to identify data pertaining to the incidence, pathophysiology, risk factors and management of DAOSD. A critical review of this literature was used to inform a decision framework for dupilumab-prescribers and develop a graded severity scoring tool to guide appropriate management options. Results: DAOSD typically emerges within 4 months of commencing dupilumab and the occurrence of new events diminishes over time. The reported incidence varies widely depending on the nature and source of the data: 8.6–22.1% (clinical trials programme), 0.5–70% (real-world data; differences in study size, duration of follow-up, ophthalmologist intervention, use of prophylaxis). Occurrence increases with AD severity and in patients with prior history of ocular disease; pathophysiology is still to be fully characterised. Management options have evolved over time and include lubricants/artificial tears, corticosteroids, calcineurin inhibitors, antihistamines, anti-inflammatory agents and antimicrobial agents. Current therapies aim to resolve symptoms or reduce severity to levels sufficiently tolerable to enable continuation of dupilumab therapy. Conclusions: Recommendations for DAOSD assessment and management include identification of high-risk patients, vigilance for red flags (keratoconus, herpetic and bacterial keratitis), regular assessment of symptom severity (before and during dupilumab therapy), conservative management of mild DAOSD by the prescribing physician and ophthalmologist referral for collaborative care of moderate–severe DAOSD and high-risk patients

Quality of life in patients with bullous dermatoses

Genetic and acquired bullous dermatoses can severely affect multiple domains of a patient's quality of life (QOL). Integrating formal evaluation of QOL into the clinical evaluation of patients facilitates an objective assessment of disease severity, mapping of disease trajectory, and captures therapeutic intervention outcomes. There have been 5 studies evaluating QOL in autoimmune dermatoses and 4 studies reviewing QOL in the genodermatoses. All literature to date indicates a significant disease burden in this setting. The development of formal QOL instruments has facilitated quantification of QOL deficits in this arena and offers promising tools for patient assessment in the future

Diffuse melanosis cutis in the setting of BRAF(V600E) mutant melanoma and treatment with targeted therapies

Diffuse melanosis cutis (DMC) is a rare presentation of metastatic melanoma associated with a particularly guarded prognosis. We report a case of a 35-year-old man with BRAFV600E metastatic melanoma treated with dabrafenib (as well as ipilimumab and whole brain radiotherapy), who is alive, 25 months after the onset of his DMC. This is significantly longer than the reported mean survival of 4 months, highlighting the importance of BRAF mutation testing and the promising survival advantage of using targeted therapies compared with conventional chemotherapeutic regimens.3 page(s

Neonatal lupus erythematosus presenting as a non-bullous histiocytoid neutrophilic dermatosis

Histopathologic findings in neonatal lupus erythematosus (NLE) are usually congruent with those of subacute cutaneous lupus erythematosus. However, neutrophilic dermatosis-type histopathologic features are being increasingly recognized in the literature including rare cases with variant histiocytoid morphology. We report the case of a 7-week-old male presenting with figurate erythema. His mother was found to have elevated anti-nuclear antibodies and was positive for anti-SSA/Ro, anti-SSB/La antibodies and Ro52 autoantibodies. The infant had a similar serological profile. Skin biopsy showed a histiocytoid interstitial infiltrate with mild lichenoid features, sparse neutrophils and mild leukocytoclasis. The histiocytoid infiltrate showed prominent CD68, CD163, and myeloperoxidase expression. Isolated clusters of CD123+ histiocytes were also present. This case highlights the rare finding of non-bullous neutrophilic dermatosis with histiocytoid change in neonatal lupus. In neonates presenting with figurate erythemas with morphological histiocytic change on biopsy, NLE should be considered as a differential diagnosis and investigated for accordingly

Diffuse melanosis cutis in the setting of BRAFV 600E metastatic melanoma

Case Report: A 79-year-old Caucasian male presented with a 1-week history of diffuse progressive blue-gray discoloration of the skin subsequently found to due to diffuse melanosis cutis (DMC) in the setting of metastatic melanoma. Mutation testing demonstrated BRAFV 600E mutation status, an unexpected finding given his age. He died two weeks after presentation. Discussion: As our understanding of the molecular subtypes of melanoma increases, in the future it may be possible to predict which melanoma patients have a predilection to developing DMC. Mutation testing of DMC patients should be considered as BRAF inhibitors, and other novel targeted therapies may improve the bleak prognosis associated with this unusual presentation of metastatic melanoma
