Abstract

Pemphigus vulgaris (PV) is a rare, yet serious autoimmune disorder primarily affecting the skin and mucous membranes. While the dermatological and mucosal aspects of PV are well-documented, the potential for systemic involvement, particularly cardiac complications, remains under-explored. This study aimed to investigate the serum cardiac troponin I (cTnI) level in patients with PV versus healthy controls. The relationship between serum cardiac troponin I (cTnI) levels and various demograpgics, clinical and laboratory characteristics in patients with PV was also dealt with. This cross-sectional study was conducted on 59 patients with pemphigus vulgaris and 59 age- and sex- matched healthy controls, visited at a tertiary care hospital from August 2021 to May 2023. After thorough history taking and physical examination, troponin level was measured by the ECL (Electrochemiluminescence) method. The correlation between serum cTnI level and various variables was evaluated using Pearson’s correlation coefficient. The mean serum cardiac troponin I (cTnI) level in patient group was 0.104 ± 0.05 ng/mL, with a range of 0.01 to 0.25 ng/mL. Despite mean cTnI level in patients was greater than controls, this difference was not reach to the significance level (P value: 0.058). The analysis revealed a significant positive correlation (r = 0.52, p = 0.005310), suggesting that higher PDAI scores were associated with elevated cTnI level. The correlation between serum cardiac troponin I (cTnI) level and PDAI score, even without any clinical sign or risk factor for cardiovascular disease suggests a potential link between the severity of PV and subtle cardiac involvement, highlighting the importance of cardiac monitoring in these patients. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.
