Pack-year cigarette smoking affects the course of palmoplantar pustulosis.

BACKGROUND: Palmoplantar pustulosis (PPP) is a chronic inflammatory disease with poorly understood pathogenesis. The disease has a chronic course with improvements and exacerbations. Due to palmoplantar location, PPP has a severely negative impact on patients' quality of life. OBJECTIVES: To identify demographic and environmental factors, concomitant diseases, medications, and bacterial factors which may affect the course of PPP. MATERIAL AND METHODS: A total of 51 patients suffering from PPP took part in the study. They were classified according to the Palmoplantar Pustulosis Psoriasis Area and Severity Index (ppPASI) into 3 groups due to the severity of the disease. Pack-year of smoking score was established as a quotient of packets smoked every 24 h and the years of being addicted. Diagnosis of metabolic syndrome was based on the IDF criteria from 2009. Chlamydia trachomatis was detected using enzyme-linked immunosorbent assay (ELISA) technique, Staphylococcus aureus by the culture swabs. Contact hypersensitivity was examined with the T.R.U.E. test. RESULTS: Significantly high severity of PPP was observed in patients addicted to smoking with a high pack-year score (p = 0.03). Significantly lower intensity of PPP lesions was observed in patients treated with ibuprofen (p < 0.01). There was no correlation between severity of PPP skin lesions and comorbidities. CONCLUSIONS: Addiction to cigarette smoking and a high pack-year score aggravates the course of PPP. Treatment with ibuprofen can improve the course of the disease.

Palmoplantar pustulosis: Factors causing and influencing the course of the disease.

Palmoplantar pustulosis (PPP) is a chronic inflammatory disease, most often occurring in middle-aged women. In the course of the condition, painful skin lesions appear on the hands and feet, i.e., areas that are extremely important in everyday life. Therefore, the disease significantly reduces quality of life. The pathogenesis of this disease is poorly understood, although it is known that genetic, immunological and environmental factors play a role in its development. Clinical observations confirm the role of nicotine and contact allergens in the development of the lesions. The skin lesions can also occur as a side effect of certain medications. In some cases, PPP coexists with other diseases, i.e., seronegative arthropathies, as well as celiac and thyroid diseases. There is also a connection between the disease and infectious bacterial foci. Exacerbation of the skin lesions is triggered by stress. Therefore, patients require multidirectional tests, since finding the cause of the disease is essential to administering effective treatment.
