Investigating the Morbidity of Glucocorticoid Use in Patients With Autoimmune Bullous Diseases (AIBDs)
Investigating the Nature and Prevalence of Glucocorticoid-related Morbidity in Patients With Autoimmune Bullous Disease (AIBD) Using the Glucocorticoid Toxicity Index (GTI)

Detailed Description
This study is an multi-centre observational trial. Patients with AIBDs are recruited based on the criteria: an age of eighteen years or above; a new or established diagnosis of autoimmune bullous disease confirmed by clinical assessment, histopathology, immunofluorescence, and enzyme-linked immunoassay (ELISA) or biochip testing; new or current use of oral glucocorticoids for the treatment of autoimmune bullous disease (Group 1, active treatment group), patients with receipt of previous oral glucocorticoid use with no current use (Group 2, steroid-sparing control group) or patients who had ceased glucocorticoids during the study (Group 3, ceased steroid group) ; attendance of at least one baseline visit (V1) and one follow-up visit during the study period; and, the provision of capacitated and informed consent.
Patients are considered for enrolment based on inclusion criteria after attendance at a bullous disease clinic at a participating study site. At the baseline visit (V1), patients are comprehensively interviewed for demographic factors (age, gender), pre-existing medical conditions, and past and current medications. Patients attend regular follow-up visits at three-month intervals, to a maximum follow-up period of 15 months (V6). Treatment plans, including glucocorticoid dose, are determined by accredited medical professionals based on the clinical condition of the patient.
The Glucocorticoid Toxicity Index (GTI) tool (Figure 1) is used to evaluate glucocorticoid toxicity at all visits, including in dermatologic, neuropsychiatric, musculoskeletal, endocrine and metabolic domains.
Myopathy was measured and graded in accordance to the GTI.
Patients were divided into three groups: Group 1 (control) comprised of patients was comprised of who were not exposed to glucocorticoids during the study period, Group 2 comprised of patients whose glucocorticoid dose was ceased during the study period. Patients who continued on glucocorticoid treatment for the duration of the study period formed the third group.

Patients with autoimmune bullous disease not currently receiving glucocorticoids
Patients with autoimmune bullous disease who have received glucocorticoids for their condition in the past, but are not currently on steroids.

|
Patients with autoimmune bullous disease receiving glucocorticoids for the duration of the study
Patients with autoimmune bullous disease currently receiving glucocorticoids for their condition, as independently assessed by an appropriately qualified medical professional/dermatologist, for the duration of the study period.
|
Glucocorticoid as calculated in prednisone oral equivalents.
|
Patients with autoimmune bullous disease ceasing glucocorticoids during the study period
Patients with autoimmune bullous disease who initially had glucocorticoid treatment at the first visit, and had ceased glucocorticoid use during the study period.

Measure Description |
Time Frame |
---|---|---|
Glucocorticoid Toxicity Score
Time Frame: 2 years
|
Glucocorticoid toxicity score as calculated by the glucocorticoid toxicity index (GTI) application licenced by Steritas. The final glucocorticoid toxicity index (GTI) score is comprised of two sub-scores. The GTI-cumulative worsening score (GTI-CWS) captures any additive glucocorticoid toxicities, transient or persistent, that are not present at baseline is scored from 0 to +439. The GTI-aggregate improvement score (GTI-AIS) assesses end-point toxicity comparative to baseline and is scored from -317 to +410; a negative score represents an improvement in toxicity, whilst a positive score indicates worsening toxicity. |
