Résumé

Abstract Background: Lichen planus is a chronic inflammatory mucocutaneous disease. Recent studies have suggested that it is associated with an increased risk of cardiovascular comorbidities. Objective: The purpose of this study was to assess and compare arterial stiffness and cardiovascular hemodynamics in patients with lichen planus and a healthy control group. Methods: Fifty-five patients with lichen planus and 42 healthy controls were enrolled. All patients underwent echocardiographic examination, and arterial stiffness was measured using applanation tonometry. Results: No statistically significant difference was determined between the patient and control groups in terms of arterial stiffness, but stiffness was markedly higher in patients with erosive lichen planus compared to the control group and other patients (p = 0.006, and p = 0.023, respectively). Moderate positive correlation was determined between duration of disease and arterial stiffness. Impairment of systolic and diastolic functions was also determined in patients with lichen planus compared to the control group (p < 0.001, and p = 0.005, respectively). Study limitations: Relatively low number of patients. Conclusion: The positive correlation observed between duration of disease and arterial stiffness in patients with lichen planus suggests that these patients should be followed-up in terms of cardiovascular risk in the presence of resistant and long-term disease, particularly in case of erosive lichen planus.

Résumé

OBJECTIVE: Lichen planus is a chronic inflammatory autoimmune mucocutaneous disease. Recent research has emphasized the strong association between inflammation and both P-wave dispersion and dyslipidemia. The difference between the maximum and minimum P-wave durations on an electrocardiogram is defined as P-wave dispersion. The prolongation of P-wave dispersion has been demonstrated to be an independent risk factor for developing atrial fibrillation. The aim of this study was to investigate P-wave dispersion in patients with lichen planus. METHODS: Fifty-eight patients with lichen planus and 37 age- and gender-matched healthy controls were included in this study. We obtained electrocardiographic recordings from all participants and used them to calculate the P-wave variables. We also assessed the levels of highly sensitive C-reactive protein, which is an inflammatory marker, and the lipid levels for each group. The results were reported as the means ± standard deviations and percentages. RESULTS: The P-wave dispersion was significantly higher in lichen planus patients than in the control group. Additionally, highly sensitive C-reactive protein, LDL cholesterol, and triglyceride levels were significantly higher in lichen planus patients compared to the controls. There was a significant positive correlation between highly sensitive C-reactive protein and P-wave dispersion (r = 0.549, p<0.001) in lichen planus patients. CONCLUSIONS: P-wave dispersion increased on the surface electrocardiographic measurements of lichen planus patients. This result may be important in the early detection of subclinical cardiac involvement. Increased P-wave dispersion, in terms of the tendency for atrial fibrillation, should be considered in these patients. .

Résumé

Las Dermatosis Liquenoides son un grupo de enfermedades frecuentes en Dermatología. La palabra liquen produce confusión a los dermatólogos, pues es utilizada indistintamente para definir un patrón histopatológico de infiltrado linfocítico en banda en la membrana basal, así como también un patrón clínico de pápulas violáceas aplanadas y brillantes. Considerando su frecuencia, es conveniente que los dermatólogos se encuentren bien familiarizados con estos conceptos en orden a realizar diagnósticos precisos y así otorgar tratamientos adecuados a estos pacientes.


Lichenoid dermatoses are a group of diseases frequently seen in dermatology. The word lichen tends to confuse dermatologists because this term describes a histopathological pattern characterized by a band-like lymphocytic infiltrate in the basal membrane, as well as a clinical pattern of flat, violet, shiny papules. Given the high number of patients suffering from this disorder, it is advisable for dermatologists to be well familiarized with these concepts in order to give an accurate diagnosis and suitable treatment.

Résumé

Os autores apresentam um caso do Líquen plano ungueal com comprovação histopatológica- no qual, além das alterações clínicas habituais, houve associação de hiperpigmentação da lâmina. São discutidas as diversas manifestações do acometimento ungueal, a evolução peculiar do caso com melhora das alterações pigmentares, além de se proceder a uma breve revisão literatura
