RESUMEN

Abstract BACKGROUND: Vitiligo is an acquired pigmentary skin disorder that affects 0.5% to 2.0% of the population. OBJECTIVE: Patients' knowledge, opinions, and attitudes about vitiligo were evaluated. METHODS: The team conducted a cross-sectional, descriptive, prospective study between June 2014 and May 2015. The study included 100 patients aged over 12 years who were diagnosed with vitiligo. A questionnaire including items on knowledge, opinions, and beliefs about vitiligo and the Illness Perception Questionnaire (IPQ) were filled out by the patients, and the results were analyzed. RESULTS: In total, 100 (58 female, 42 male) patients were included in the study. Of them, 74% knew the name of their disease, 90% thought that vitiligo was not contagious, 48% reported that they obtained information on the disease from a doctor, and 69% believed they had adequate information on vitiligo. Eighty percent reported no negative effects from vitiligo on relationships with friends or family. It was believed that stress, excessive sun exposure, and heredity were causes of vitiligo, according to 84%, 37%, and 22% of the patients, respectively. Thirty-six patients (36%) believed that their illness was a serious disease and 35% deemed that it did not have a major impact on their lives. CONCLUSIONS: Our results show that vitiligo patients were generally highly aware of their condition. The disease did not negatively affect patient opinions or attitudes about vitiligo. The authors believe that improving patient-physician communication will impact positively on the course of the disease.

RESUMEN

BACKGROUND: Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the general population. The nails may be affected in patients with an autoimmune disease such as psoriasis, and in those with alopecia areata. It has been suggested that nail abnormalities should be apparent in vitiligo patients. OBJECTIVE: We sought to document the frequency and clinical presentation of nail abnormalities in vitiligo patients compared to healthy volunteers. We also examined the correlations between nail abnormalities and various clinical parameters. METHODS: This study included 100 vitiligo patients and 100 healthy subjects. Full medical histories were collected from the subjects, who underwent thorough general and nail examinations. All nail changes were noted. In the event of clinical suspicion of a fungal infection, additional mycological investigations were performed. RESULTS: Nail abnormalities were more prevalent in the patients (78%) than in the controls (55%) (p=0.001). Longitudinal ridging was the most common finding (42%), followed by (in descending order): leukonychia, an absent lunula, onycholysis, nail bed pallor, onychomycosis, splinter hemorrhage and nail plate thinning. The frequency of longitudinal ridging was significantly higher in patients than in controls (p<0.001). CONCLUSIONS: Nail abnormalities were more prevalent in vitiligo patients than in controls. Systematic examination of the nails in such patients is useful because nail abnormalities are frequent. However, the causes of such abnormalities require further study. Longitudinal ridging and leukonychia were the most common abnormalities observed in this study.

RESUMEN

BACKGROUND: Vitamin D plays a key role in the immune responses generated by lymphocytes and antigen-presenting cells. Decreased vitamin 25-hydroxyvitamin D (25(OH)D) levels have been implicated in several allergic disorders and association between 25(OH)D levels and chronic urticaria (CU) symptom scores has been evaluated in a few studies. This study was performed to assess the effects of vitamin D supplementation on the symptoms and quality of life scores in chronic spontaneous urticaria (CSU) and to vitamin D levels in CSU patients in comparison with controls. PATIENTS AND METHODS: Fifty-eight CSU patients and forty-five controls were included in the study. The patients were divided into two groups according to severity of the disease; as mild/moderate and severe urticaria. Serum 25-hydroxyvitamin D (25(OH)D) concentrations were measured in serum of CSU patients and compared with the control groups. In patients with 25(OH)D concentrations lower than 30 µg/L, 300 000 IU/month of vitamin D3 supplementation was added to standard therapy. The clinical improvement was evaluated after 3 months with urticaria activity score (UAS4) and Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL). RESULTS: Serum 25(OH)D concentration was significantly lower in CSU group compared to healthy subjects (p < 0.001). The prevalence of vitamin D deficiency (<20 (µg/L) and insufficiency (<30 µg/L) was significantly higher in CSU patients than control groups. In addition, 25(OH)D concentrations were significantly lower in both mild-moderate and severe CSU patients than those of the controls (p = 0.011 and p < 0.001, respectively). Ninety eight percent of patients (25(OH)D < 30 µg/L) were treated with vitamin D3 (300 000 IU/month) supplementation, and after 12 weeks, these patients showed significant improvements in UAS4 and CU-Q2oL scores. CONCLUSION: This study support the contributing and beneficial effects of vitamin D in the treatment of CU. Replacement of vitamin D may provide improvement in both the severity of symptoms and the quality of life scores in these patients.

RESUMEN

BACKGROUND: Visfatin is an adipokine produced by visceral adipose tissue and has insulin-mimicking effects. Fetuin-A is a hepatic secretory protein that binds the insulin receptor and inhibits insulin action both in vivo and in vitro. The authors of the present study aimed to investigate the levels of serum visfatin and fetuin-A and their correlation with hemoglobin A1c (HbA1c) and urine albumin levels in patients with type 2 diabetes mellitus (T2DM). METHODS: A total of 40 obese patients with T2DM (11 males and 29 females; age, 54.47±10.83 years and 23 obese nondiabetic controls (8 males and 15 females; age, 53.04±11.33 years) were included in the study. Age, sex, and body mass index were similar in the 2 groups. Serum visfatin and fetuin-A levels were measured by enzyme-linked immunosorbent assay. HbA1c and urine albumin levels were measured by high performance liquid chromatography and nephelometric method, respectively. RESULTS: Serum levels of visfatin in patients with T2DM (4.03±2.44 ng/mL) were similar to the control group (3.65±3.02 ng/mL). Serum fetuin-A levels were significantly lower in patients with T2DM than the controls (298.75±78.86 and 430.73±94.46 µg/mL, respectively). HbA1c levels were significantly higher in the T2DM group compared with controls (7.33±1.32 and 5.44±0.84%, respectively). Correlations between visfatin, fetuin-A and HbA1c levels were not observed. CONCLUSION: The present study suggests fetuin-A may play a role in the pathogenesis of T2DM.
