Body mass index, HbA1c and serum C-reactive protein are predictors of secondary failure in infliximab continuance for Japanese psoriasis patients: A hospital-based retrospective case-control study

Hyperglycemia Is a Potential Prognostic Factor for Exacerbation in Severe Psoriasis with Diabetes or Prediabetes

Background

Psoriasis is an immune-mediated skin disease with a chronic relapsing-remitting course. Hyperglycemia has been shown to correlate with psoriasis severity. However, whether it could trigger psoriasis flares is not known.

Objective

To investigate the association between hyperglycemia and psoriasis exacerbation.

Methods

We conducted a retrospective cohort study at a university-affiliated hospital in Bangkok, Thailand, between 2008 and 2022 to examine the effects of elevated HbA1c on psoriasis flares. Patients with psoriasis vulgaris and either type 2 diabetes mellitus (T2DM) or impaired fasting glucose (IFG) who had at least 2 HbA1c values were identified. Statistical analyses were performed using mixed-effects logistic regression.

Results

A total of 201 psoriasis patients (95 with severe psoriasis and 106 with mild psoriasis) with 1,717 follow-up visits were included in the analysis. In patients with severe psoriasis, HbA1c ≥ 7% (adjusted odds ratio (OR): 1.905 (95% confidence interval: 1.328-2.731)) and alcohol consumption status (adjusted OR: 3.328 (1.235-8.965)) were identified as independent prognostic factors for psoriasis flares. Meanwhile, in mild psoriasis patients, none of the variables were independently associated with psoriasis flares.

Conclusion

Hyperglycemia and alcohol consumption were associated with exacerbation in patients with severe psoriasis who had T2DM/IFG.

Biologics for Reducing Cardiovascular Risk in Psoriasis Patients

Psoriasis is a chronic inflammatory skin disease with a high prevalence of cardiovascular disease (CVD), obesity, dyslipidemia, hypertension, diabetes mellitus, and metabolic syndrome. Among them, CVD is the most common cause of morbidity and mortality in psoriasis patients. Since CVD is associated with considerable morbidity and mortality, primary care clinicians are increasingly committed to reducing the risk of CVD in patients with psoriasis. Biologics targeting TNF-α, IL-12/23, and IL-17 are systemic therapies that can dramatically improve the condition of psoriasis. Recent studies have reported that these inflammatory cytokine signals may promote atherosclerosis, suggesting that biologics might be effective for improving psoriasis as well as reducing the risk of CVD. Here, we reviewed cardiovascular risk in psoriasis patients, the association between psoriatic inflammation and atherosclerosis, and the efficacy of biologics for reducing the risk of cardiovascular diseases.

Characterization of rosacea patients in Tohoku area of Japan: Retrospective study of 340 rosacea cases

Rosacea is a chronic inflammatory skin disease with facial redness and acne-like papules and pustules. The characteristics and background of rosacea patients in Japan have not been well documented. In this study, we retrospectively collected the medical information of rosacea patients, and investigated the background, complications, exacerbating factors, and status of allergy. Between January 2010 and December 2020, 431 cases were diagnosed as rosacea or rosacea-like dermatitis. We selected 340 patients, in which we could confirm telangiectasia on facial skin. Females and males numbered 266 and 74, respectively. The average age of the first visit was 51.5 years, and the youngest and oldest were 11 and 88 years old. Among 340 cases, 323 had erythematotelangiectatic rosacea, 97 papulopustular rosacea, 20 phymatous rosacea presenting as rhinophyma, and four had symptoms of ocular rosacea. The most common complication was hay fever (93 individuals, 27.4%), and 66 (19.4%) had a medical history of contact dermatitis. Temperature differences (141 individuals, 41.5%) were the most common exacerbating factor followed by sunlight exposure (60 individuals, 17.6%). Seventy-eight individuals received allergen-specific immunoglobulin (Ig)E tests, and IgE for cedar was the most frequently observed (46 individuals, 59.0%). High frequencies of IgE for Dermatophagoides pteronyssinus or D. farinae (33 individuals, 42.3%) and house dust I (31 individuals, 39.7%) suggested that environmental conditions at home would affect rosacea symptoms. Since the facial skin is exposed to environmental stimuli every moment, this retrospective observation suggested the importance of the daily lifestyle guidance as well as medical treatments.
