Interest has increased in comorbidities associated with psoriasis and their effects on health‐related quality of life (HRQoL). This study aimed to evaluate the prevalence of metabolic syndrome (MetS) and psoriatic arthritis (PsA) and to investigate HRQoL and the prevalence of hypertension, type 2 diabetes mellitus (T2DM), obesity and dyslipidemia. In a cross‐sectional design, patients diagnosed with plaque psoriasis answered an interview and standardized questionnaires (Dermatology Life Quality Index questionnaire [DLQI], 36‐Item Short Form Health Survey [SF‐36] and EuroQol Five‐Dimension Questionnaire Three‐Level version [EQ‐5D‐3L]). Physical examination and several tests to assess desired outcomes were performed by a dermatologist and a rheumatologist during three visits. The prevalence of MetS and PsA was 50.0% and 41.8%, respectively. Dyslipidemia was the most prevalent (74.5%) secondary comorbidity, followed by hypertension (61.8%), obesity (52.5%) and T2DM (30.9%). The mean (standard deviation) DLQI score was 6.5 (6.9), and mean physical and mental SF‐36 measures were 45.2 (10.4) and 45.5 (12.3), respectively, and for EQ‐5D‐3L, mean utility index and EQ‐VAS scores were 0.68 (0.27) and 72.7 (19.7), respectively. PsA and MetS are important comorbidities; a reduced HRQoL is noted among plaque psoriasis patients with these comorbidities, emphasizing the relevance of diagnosis and treatment beyond the care of skin lesions.

Objective This study was designed to develop a severity index for geographic tongue (GT) based on the Psoriasis Area and Severity Index. Study Design This cross-sectional observational study, with a retrospective sample of 100 participants, included 5 photographs of each case (dorsum, right border, left border, apex, and lingual belly), totaling 500 images of GT, which were evaluated by 3 experienced researchers in the area of GT and psoriasis. At the end of the analysis, GT was classified as mild, moderate, or severe. Results Of the 100 patients, white women were most prevalent, accounting for 53% of cases. Of these participants, 34% had psoriasis and 24% reported a burning sensation. The values of the proposed new index obtained at time 1 (0.855) and time 2 (0.819) presented low variability, and intra- and interrater correlations produced satisfactory values ranging from 0.950 to 0.898 and 0.898 to 0.850, respectively. Conclusion The new index, Geographic Tongue Area and Severity Index, provides a better characterization of GT by assessing the severity of lesions in an easy and reliable manner, and it is indicated as a first step for interpreting the condition in clinical routines and clinical trials.

Background Few studies have examined the clinical features of geographic tongue (GT), an inflammatory lesion, making diagnosis and the investigation of oral psoriasis difficult. Purpose To investigate the clinical features of GT to facilitate its identification and understand its relationship with psoriasis. Methods A total of 96 participants diagnosed with GT underwent stomatological and dermatological examinations. The parameters assessed were burning sensation; number, classification, and location of lesions; loss of papillae; severity of GT lesions; and association with fissured tongue (FT). Psoriatic patients (PS) and those without psoriasis (NPS) were compared. Results Burning sensation was reported by 45 (47%) patients, 67 (70%) patients showed active GT, 68 (71%) presented with typical lesions, and 59 (61%) exhibited moderate lesions. GT was associated with FT in 75% of the cases and exhibited a diffused pattern associated with severe lesions. It was also more frequent in the PS group. The comparative analysis between the PS and NPS groups showed significant differences between the groups with regard to gender, presence of burning sensation, and GT severity. Conclusion GT is a symptomatic lesion with a thick halo. In contrast, psoriatic patients are frequently asymptomatic and exhibit severe lesions with greater loss of papillae that are associated with severe FT. The present study is the first to demonstrate clinical differences in the GT of patients with and without psoriasis, suggesting that some GT cases may represent true oral psoriasis and some cases may represent only GT.

The platelet-rich plasma (PRP) has proved promising regarding its applicability in dermatology, especially in the healing of chronic ulcers. The autologous platelet-rich plasma is obtained by centrifuging the blood, so that the components are separated by density gradient. The final product is a gel rich in growth factors that act in tissue repair by activating fibroblasts and inducing extracellular matrix remodeling.

Geographic tongue (GT) and fissured tongue (FT) are the more frequent oral lesions in patients with psoriasis. The aims of this study were to compare the prevalence of GT/FT between psoriasis group (PG) and healthy controls (HC) and investigate the correlation between GT/FT and psoriasis severity using the PASI and age of psoriasis onset. Three hundred and forty-eight PG and 348 HC were selected. According to the age of psoriasis onset, the individuals were classified as having early psoriasis and late psoriasis. The severity of vulgaris psoriasis was determined according to PASI. A follow-up was conducted in patients with psoriasis vulgaris (PV) with GT to evaluate the progression of oral and cutaneous lesions. The FT and GT were more frequent in PG than in HC. The incidence of GT was higher in patients with early psoriasis and that of FT in late-psoriasis. There is association between psoriasis intensity and GT; and a higher monthly decrease of PASI score in patients without GT. The presence of GT and FT is higher in PG than in the HC. GT is associated with disease severity and may be a marker of the psoriasis severity.

Background Infections are known to trigger and exacerbate psoriasis. Although oral candidiasis is often clinically diagnosed, it is not always confirmed by laboratory tests such as oral cytopathology. Objectives The aims of this study were to determine the prevalence of oral candidiasis in patients with psoriasis through clinical and cytopathological diagnosis and to investigate the association between oral candidiasis and psoriasis with regards to the severity of the clinical presentation and the type of treatment for psoriasis. Methods A total of 140 patients with psoriasis and 140 healthy control subjects received an oral examination. Scrapings of the tongue were also obtained for a cytopathological examination. Results The oral examination and the results of the cytopathological smear revealed 37 (26%) cases of candidiasis in the patients with psoriasis and no cases of candidiasis in the healthy control subjects. There was no correlation between the type of psoriasis treatment and the presence of oral candidiasis ( P = .616). There was a statistically significant association ( P = .033) between the clinical severity of psoriasis and the presence of Candida . Limitations This study was limited by the small number of subjects and the lack of follow-up to determine the development of psoriasis after treatment for oral candidiasis. Conclusions The presence of oral candidiasis is higher in patients with psoriasis and it is associated with disease severity. This increased presence of oral candidiasis was apparent despite any type of treatment for the psoriasis. Cytopathology to rule out oral candidiasis should be used in the routine medical workup of patients with psoriasis.
