Psoriasis in hypertension patients significantly increases mortality risk, claims study published in PLoS One.
The linkage between psoriasis and hypertension has been established through observational studies. Despite this, a comprehensive assessment of the combined effects of psoriasis and hypertension on all-cause mortality is lacking. The principal aim of the present study is to elucidate the synergistic impact of psoriasis and hypertension on mortality within a representative cohort of adults residing in the United States. The analysis was conducted on comprehensive datasets derived from the National Health and Nutrition Examination Study spanning two distinct periods: 2003–2006 and 2009–2014. The determination of psoriasis status relied on self-reported questionnaire data, whereas hypertension was characterized by parameters including systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥ 90 mmHg, self-reported physician diagnosis, or the use of antihypertensive medication. The assessment of the interplay between psoriasis and hypertension employed multivariable logistic regression analyses. Continuous monitoring of participants’ vital status was conducted until December 31, 2019. A four-level variable amalgamating information on psoriasis and hypertension was established, and the evaluation of survival probability utilized the Kaplan-Meier curve alongside Cox regression analysis. Hazard ratios (HRs) and their associated 95% confidence intervals (CIs) were computed to scrutinize the correlation between psoriasis/hypertension and all-cause mortality. Results: In total, this study included 19,799 participants, among whom 554 had psoriasis and 7,692 had hypertension. The findings from the logistic regression analyses indicated a heightened risk of hypertension among individuals with psoriasis in comparison to those devoid of psoriasis. Throughout a median follow-up spanning 105 months, 1,845 participants experienced all-cause death. In comparison to individuals devoid of both hypertension and psoriasis, those with psoriasis alone exhibited an all-cause mortality HR of 0.73 (95% CI: 0.35–1.53), individuals with hypertension alone showed an HR of 1.78 (95% CI: 1.55–2.04), and those with both psoriasis and hypertension had an HR of 2.33 (95% CI: 1.60–3.40). In the course of a stratified analysis differentiating between the presence and absence of psoriasis, it was noted that hypertension correlated with an elevated risk of all-cause mortality in individuals lacking psoriasis (HR 1.77, 95% CI: 1.54–2.04). Notably, this association was further accentuated among individuals with psoriasis, revealing an increased HR of 3.23 (95% CI: 1.47–7.13). The outcomes of our investigation demonstrated a noteworthy and positive association between psoriasis, hypertension, and all-cause mortality. These findings indicate that individuals who have both psoriasis and hypertension face an increased likelihood of mortality.
