Is microRNA 1910-3p (miR-1910-3p) a really distinctive marker for psoriasis?

Background/aim: Although the cause of immune activation in the pathogenesis of psoriasis is still unclear, miRs are thought to have an effect on psoriasis. This work aimed to evaluate the role of miRs (miR-4649-3p, miR-6867-5p, miR-4296, miR-210, and miR-1910-3p) that target the FOXP3 mRNA and IL-17A mRNA in psoriasis. Materials and methods: Forty-four psoriasis patients and 44 healthy controls were included in the study. Quantitative real-time PCR (qRT-PCR) was used for the measurement of miRs. Serum IL-17A levels were determined by an enzyme-linked immunosorbent assay (ELISA) method. Results: Plasma miR-1910-3p levels were significantly lower in the patient group than the controls (P = 0.000, fc: 0.10). ROC analysis showed that plasma miR-1910-3p levels could significantly differentiate psoriasis patients from healthy controls [AUC = 0.912 (0.848­ 0.975), P = 0.000]. The plasma miR-4649-3p level was significantly higher in the psoriasis group compared to the controls (P = 0.000, fc: 2.99). Conclusion: Decreased expression of miR-1910-3p increases the risk of developing psoriasis by approximately 50-fold and was able to use for the significant differentiation of psoriatic patients from healthy controls.

Effects of isotretinoin on body mass index, serum adiponectin, leptin, and ghrelin levels in acne vulgaris patients.

INTRODUCTION: Isotretinoin has been successfully used for the treatment of acne vulgaris. AIM: To investigate the effects of isotretinoin on body mass index (BMI), to determine whether isotretinoin causes any changes in serum adiponectin, leptin, and ghrelin levels in acne vulgaris patients, and to correlate variables. MATERIAL AND METHODS: Thirty-two patients were included in this study. Oral isotretinoin was begun at a dose of 0.5-0.6 mg/kg and raised to 0.6-0.75 mg/kg. Pretreatment and posttreatment third-month BMI and adiponectin, leptin, and ghrelin serum levels were measured. RESULTS: The pre- and posttreatment BMI values were not significantly different. In addition, serum adiponectin and leptin levels were significantly increased following isotretinoin therapy while serum ghrelin levels were not different. CONCLUSIONS: Isotretinoin may exert its anti-inflammatory activity by increasing leptin and adiponectin levels.

The Role of EREG, PTPN1, and SERPINB7 Genes in the Pathogenesis of Psoriasis: May SERPINB7 Be Protective and a Marker of Severity for Psoriasis?

INTRODUCTION: Psoriasis is a chronic inflammatory dermatological disease with complex pathogenesis in which many immune system cells, including keratinocytes, play a role. Many genes regulate the proliferation of keratinocytes and other immune cells that have essential roles in the pathogenesis of psoriasis. The expressions of EREG, PTPN1, and SERPINB7 genes were shown as upregulated in psoriatic skins in a few studies previously. OBJECTIVES: We aimed to evaluate the expressions of these genes in psoriatic lesional skin and compared them with non-lesional adjacent skin of the same patients and normal skin of healthy controls. RESULTS: Our results revealed that the expressions of EREG and PTPN1 genes were upregulated, whereas the SERPINB7 gene expression was down regulated in the psoriatic skin of the patients than normal skin of controls. Moreover, the expression level of the SERPINB7 gene was also negatively correlated with the severity of the disease among patients. CONCLUSIONS: According to our results, overexpression of EREG and PTPN1 genes, and decreased expression of SERPINB7 gene may lead to the development of psoriasis.

Assessment of hearing loss in patients with rosacea.

OBJECTIVES/AIMS: Rosacea is not only a skin condition but a systemic inflammatory disease that includes chronic inflammation, vascular alterations, and autoimmunity in pathogenesis. We aimed to evaluate the presence of a sensorineural hearing loss in the patients with rosacea in comparison with the healthy control group and, also to compare the audiometric results according to the severity of disease among the patient group. METHODS: Fifty-three patients with erythematelangiectatic or papulopustular type of rosacea and 105 age- and sex-matched healthy controls were included. Each participant had audiometric measurements after a complete ear-nose-throat examination by the same otorhinolaryngologist. RESULTS: The results of air and bone conduction thresholds showed statistically significant differences in particularly high frequencies between the groups in both the right and left ear (for all p < 0.05), but there was no correlation between audiometric measurements and the severity or the type of rosacea (p > 0.05). CONCLUSIONS: Regardless of disease severity or type, rosacea patients are likely to have sensorineural hearing loss, and it is important to refer these patients in the early period.

Effect of the Mediterranean diet in patients with chronic spontaneous urticaria.

OBJECTIVE: Patients with chronic spontaneous urticaria often want to be informed about dietary modifications. There have been many studies evaluating dietary approaches in chronic spontaneous urticaria. In this study, we aimed to investigate the relationship between adherence to the Mediterranean diet and chronic spontaneous urticaria. METHODS: In this cross-sectional case-control observational study, 100 patients (70 males and 30 females, mean age: 38.6±13.0 years) with chronic spontaneous urticaria and age- and sex-matched 100 healthy controls 70 males and 30 females, mean age: 38.7±13.8 years) were enrolled. A validated 14-item questionnaire evaluating the Mediterranean diet score was used for the assessment of adherence to the Mediterranean diet. The severity and the control of chronic spontaneous urticaria were assessed by Urticaria Activity Score over 7 days and Urticaria Control Test, respectively. RESULTS: The mean Mediterranean diet score in the patient group was 5.40±1.88, whereas in healthy controls it was 6.30±1.39 (p<0.001). The Urticaria Activity Score over 7 days score of the patients was negatively correlated with the Mediterranean diet score, whereas the Urticaria Control Test score was positively correlated. CONCLUSION: We reported that adherence to the Mediterranean diet may be an independent factor that decreases the risk of chronic spontaneous urticaria. It may also reduce the severity of chronic spontaneous urticaria symptoms.

Comparison of quality of life in patients with androgenetic alopecia and alopecia areata.

BACKGROUND: Androgenetic alopecia is one of the most common forms of hair loss. Alopecia areata is a common autoimmune disorder which causes hair loss. It has been previously reported that both alopecia disorders can have negative effects on quality of life. However, only a few studies have compared the effects of the two disorders. OBJECTIVE: The aim is to show the impact of alopecia on patients' quality of life and compare patients with androgenetic alopecia and alopecia areata. METHODS: 82 androgenetic alopecia and 56 alopecia areata patients were recruited. All patients were evaluated with the Hairdex scale and dermatology quality of life instrument in Turkish (TQL), and the scores were statistically compared according to age, sex, employment and education status, and severity of illness in the two groups. Also, female patients were statistically evaluated according to whether they wore headscarves. RESULTS: Androgenetic alopecia patients had significantly higher total Hairdex scores in terms of emotions, functioning, and symptoms, while self-confidence was significantly higher in the alopecia areata patients. No significant differences were found in stigmatization or TQL scores between groups. The Hairdex scale and TQL scores did not show differences between the groups in terms of wearing headscarves. STUDY LIMITATIONS: The validity and reliability of the Hairdex index have not been established in Turkey. CONCLUSIONS: Based on the Hairdex scale, our findings revealed that androgenetic alopecia patients are more affected by their disorder than alopecia areata patients. Although androgenetic alopecia is common and neither life-threatening nor painful, it is a stressful disorder with increased need for improvement in the patient's quality of life.
