RESUMEN
BACKGROUND: Glucocorticoids are the mainstay of treatment for autoimmune blistering diseases (AIBDs). The Glucocorticoid Toxicity Index (GTI) is a novel, outcome-based glucocorticoid-induced adverse effects monitoring instrument. OBJECTIVE: To investigate whether the GTI score was able to accurately quantify the glucocorticoid-induced toxicity in patients with AIBDs. METHODS: The prospective cohort study included patients with confirmed diagnoses of AIBDs (group1, currently receiving glucocorticoids; and group 2, had glucocorticoids ceased earlier). Data were collected minimally at baseline (V1) and 3 months (V2). Further data from patients who were able to complete the follow-up visits at 6 months (V3) and 12 months (V4) amid the COVID-19 pandemic were also included. GTI scores were calculated after data collection. RESULTS: Analysis of data from V1 and V2 found a linear correlation between GTI score and prednisone doses (P < .05) and a significant difference in GTI scores between group1 and group 2 (P < .05). Data from V3 and V4 suggested that GTI scores continued to rise progressively alongside increasing cumulative prednisone dose. LIMITATIONS: Small sample size, further exacerbated by the COVID-19 pandemic. Single-center study. CONCLUSION: The GTI sensitively and specifically captured the changes in glucocorticoids toxicity over time among patients with AIBDs. The GTI could be a feasible tool that can be used in future clinical trials as a glucocorticoid-induced toxicity outcome measure.
RESUMEN
Autoimmune and inherited bullous disorders are rare skin diseases that may have a profound negative impact on quality of life (QOL). Common symptoms include pain, pruritus, and scarring, and complications may result in the loss of the ability to perform daily tasks. Diagnosis may have a negative psychological impact, and ongoing management may require a significant allocation of time and resources by both patients and providers. To provide patient-centered care, consideration of these factors is of utmost importance for the dermatologist treating patients with bullous disorders. Herein, we present a review of the primary literature evaluating QOL in autoimmune and inherited bullous disorders, including pemphigus, pemphigoid, epidermolysis bullosa, and Hailey-Hailey disease.
RESUMEN
PURPOSE: Autoimmune bullous dermatoses (AIBD) are rare, severe diseases resulting from some antibodies activity against the different adhesion structures within the skin and/or mucosa. Few studies investigated quality of life (QOL) in AIBD by generic and dermatology-specific instruments, all reporting strong impact on QOL. Recently, disease-specific measurement tools have been developed: Autoimmune Bullous Disease Quality of Life (ABQOL) and Treatment of Autoimmune Bullous Disease Quality of Life (TABQOL) questionnaires. The aim of this study was to test the reliability and validity of ABQOL and TABQOL by developing the first foreign language versions and to evaluate ABQOL and TABQOL in Polish patients. MATERIAL AND METHODS: The study enrolled 80 patients from the tertiary referral center for AIBD at the outpatient clinic or on admission to the hospital. Sixty six patients completed the 17-item questionnaires of each ABQOL and TABQOL at day 0 and after 5-7 days. Both questionnaires were translated into Polish according to protocol. RESULTS: The internal consistency and test-retest reliability were high (Cronbach α=0.95 for ABQOL, α=0.87 for TABQOL), (R=0.98 for ABQOL, R=0.86 for TABQOL). In convergent validity, the correlation of ABQOL and TABQOL was strong (R=0.81), but low with objective disease activity scales. The strongest impact of AIBD on QOL has been observed in flares and in patients with the onset below 70 years of age. The patients with bullous pemphigoid had the highest QOL compared to other AIBD patients. CONCLUSIONS: The ABQOL and TABQOL are reliable and valid instruments for the assessment of QOL in AIBD.
