Melasma is a chronic hyperpigmentation disorder. Although several treatment methods are used for patients, it remains a challenging problem for physicians. Erbium-YAG laser is one of the laser ...treatment methods that proved its efficacy in melasma treatment. We aimed to compare the efficacy of combining the fractional Er: YAG laser and Kligman’s formula with Kligman’s formula alone in the treatment of melasma. Twenty female patients with bilateral melasma were randomly treated in a split-face controlled manner with a fractional Er: YAG laser followed by Kligman’s formula on one side and Kligman’s formula on the other side. All patients received three laser sessions with four-week intervals. The efficacy of treatments was determined through photographs, Visioface, and Melasma Area Severity Index (MASI) score, all performed at baseline and three months after the end of laser sessions. Fractional Er: YAG laser and Kligman’s formula showed a significant decrease in MASI score than Kligman’s formula alone (
P
= 0.005). There was a significant decrease in cheek Visioface score on Er: YAG laser and Kligman’s formula vs Kligman’s formula (
P
= 0.02). However, the Patient Global Assessment Scale of both sides was not statistically significant (
P
= 0.23). The combination of Fractional Er: YAG laser with Kligman’s formula is an effective treatment method for melasma.
Lichen planopilaris (LPP) is one of the important causes of cicatricial alopecia. We aimed to evaluate the efficacy and safety of low-dose naltrexone (LDN) in the setting of a clinical trial in ...patients with LPP.
We included patients with LPP between 2018 and 2020. Patients were allocated to two groups. The first group received topical clobetasol plus oral low dose naltrexone (3 mg) while the second received topical clobetasol plus placebo. The assessment was made for the disease severity by lichen planopilaris activity index (LPPAI) instrument and the safety of the drug in 2-month intervals up to 6 months. To compare both groups, we used the ANOVA test for repeated measures. Clinical trials registry code: IRCT20180809040747N1.
Thirty-four patients were analyzed in an intention-to-treat fashion. There was a decrescendo pattern on LPPAI scores that was statistically significant within the LDN (p = .001) but almost significant within the placebo group (p = .060) and non-significant between the groups (p = .813). The side effects attributable to the low dose naltrexone was not statistically different between studied groups.
Low-dose naltrexone (3 mg) failed to improve the severity of the LPP more than what is achievable with topical clobetasol.
Introduction: Vitiligo is a common pigmentation disorder manifested by white macules and patches. It is accompanied by some autoimmune and neurological diseases. Recently, it has been suggested that ...multiple sclerosis (MS) is more common in vitiligo patients and that they have a higher risk of developing MS during their lifetime. Objectives: In this study, we aimed to determine the prevalence of MS in patients with vitiligo and their first-degree relatives and compare it with the prevalence in the population. Methods: In this cross-sectional study, data were consecutively collected from patients referred to Razi Hospital from March 2020 to December 2021. Results: 709 patients with vitiligo participated in this study, and 15 reported a history of MS (2.12%, 95% CI: 1.06-3.17%). This rate was significantly higher than the prevalence of MS in the average population of Tehran (p < 0.001). Of the 2886 first-degree relatives of the patients, 10 had MS (0.35%, 95% CI: 0.13-0.56%), which was higher than the prevalence of MS, yet not statistically significant. Conclusions: A significant association between vitiligo and MS was observed, which should be of clinical and therapeutic importance. However, the prevalence of MS in first-degree relatives of vitiligo patients was higher than the average rate, yet not statistically significant.
Alopecia areata is a relapsing hair disorder characterized by a sudden hairloss and has a considerable impact on patient’s quality of life. The goal of this study was to determine quality of life ...among patients with mild and severe forms of alopecia areata and compare the two groups.
During one year, 176 patients (96 mild, 80 severe) were selected and asked to complete Dermatology Life Quality Index (DLQI) questionnaires.
Our study revealed that the severe group was predominantly female and had higher amount of unemployment, more prolonged disease duration, unstable disease course and facial involvement. The mean DLQI scores in the severe and mild groups were 10.7±7.5 and 5.4±6.8, respectively which was significantly different and severe group had higher DLQI scores and more quality of life impairment. As well, there was a significant association between total DLQI scores and acute stress during last 6 months.
Our study confirms that alopecia areata considerably impacts quality of life and this is more pronounced in patients with severe disease and those who had acute stress recently.
Pemphigus vulgaris (PV) is a rare but seriously disabling disorder of the skin and mucous membranes that can gravely impact the quality of life (QoL) of patients.
The aim of the present study was to ...identify how family members of patients with PV are affected by the disease.
A total of 118 patients with confirmed PV and one of their family members (caregivers) were enrolled in the study. To calculate disease severity, the Autoimmune Bullous Skin Disorder Intensity Score was used. The Persian version of the Dermatology Life Quality Index (DLQI) questionnaire was used to evaluate the QoL of patients and the Family Dermatology Life Quality Index (FDLQI) to evaluate the QoL of caregivers.
The mean age of patients was 43.14 ± 12.5 years. Ninety patients (76.3%) were female. Eighty-one patients (68.6%) had the mucocutaneous phenotype and 37 cases (31.4%) the mucosal phenotype. The DLQI score was 10.1 ± 7.1 for patients. The DLQI score was higher for patients with the mucocutaneous phenotype (11.8 ± 7.5) than those with the mucosal phenotype (6.4 ± 4.9; p < .001). QoL was significantly affected by disease severity. FDLQI score was 13 ± 7 for caregivers, and was significantly higher in older caregivers and married ones. There was a positive correlation between patients’ admission frequencies and FDLQI score. FDLQI score was also significantly affected by the Autoimmune Bullous Skin Disorder Intensity Score of patients’ disease severity. The QoL of patients and their caregivers showed a significant positive correlation.
The QoL of patients and their families are impaired significantly, and is considerably prominent in the mucocutaneous phenotype of PV and more severe forms.
Pemphigus Disease Area Index (PDAI) and Autoimmune Bullous Disease QoL (ABQoL) were not used in this study.
Prolactin is a hormone; in addition to it known roles, it has immunomodulatory effects on lymphocytes maturation and immunoglobulins production. Hyperprolactinemia has been demonstrated in various ...autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, type I diabetes mellitus, and Graves’ disease. In view of the prolactin immunomodulatory roles, studying prolactin levels in pemphigus as an autoimmune blistering disease may introduce new ways of understanding disease etiology and developing treatment strategies.
Our purpose was to determine the prolactin levels in patients with newly diagnosed pemphigus vulgaris and study its correlation with pemphigus disease area index.
Our study was limited by the lack of a control group.
In this cross-sectional study, prolactin and anti-desmoglein 1 and 3 autoantibodies levels were measured in 50 patients with newly diagnosed pemphigus vulgaris in Razi Dermatology Hospital. Pemphigus severity and extent was estimated using the Pemphigus Disease Area Index.
Of the 50 patients, 18 were male and 32 were female with a mean age of 41.56 ± 13.66 years. Mean prolactin (PRL) level was 15.60 ± 11.72 ng/ml (10.68 in males and 18.37 in females). Mean anti-desmoglein 1 and 3 autoantibodies were 135.8 ± 119.8 and 245.8 ± 157.4 U/ml, respectively. Eleven out of 50 patients had a higher than normal prolactin range. No relation was found between prolactin level and disease activity (p = .982). Also, correlation studies show no relation between prolactin and anti-desmoglein 1 and 3 autoantibodies levels (respectively, p = .771 and .738). In comparing the extent of the disease between the two groups with normal and high prolactin, paired t-test showed no significance (p = .204).
In our study, 22% of patients had hyperprolactinemia, which was greater among females. The highest PRL level was detected in mucocutaneous group. Although serum PRL levels were higher in patients with a greater Pemphigus Disease Area Index, it did not reach statistical significance.
Psoriasis is a chronic relapsing disorder that involves the skin, nails and joints. With regard to the role of the immune system in psoriasis, the current study compared serum IgE concentration in ...patients with psoriasis with control group. Current case-control study was conducted in Dermatology clinic of Razi hospital, Tehran University of medical sciences, Tehran, Iran in 2012. Fifty-eight patients with psoriasis e referred to the clinic were assigned as patient group and 58 healthy subjects with matched age and sex as a control group. Patient's history, family history and demographic characteristics such as age and sex, duration and severity of disease using PASI, were collected and entered into a form. Consent form was obtained from participants. Serum IgE concentrations of both study groups were measured by electrochemiluminescence assay in the laboratory A total number of 58 patients with psoriasis, mean age of 44.15 (19-76 years) and 58 controls with matched age and sex were studied. Mean average of serum IgE concentration in the control group was 115.13 versus 200/06 concentration in patients group (P=0.16). Serum IgE concentration in 22.4% of patients versus 17.2% in controls was greater than normal concentration (P=0.48). No significant correlation was between serum IgE concentration and disease severity using PASI (P=0.11, r=0.21), neither a significant correlation with disease duration, age and gender. According to the present study, serum IgE concentrations are not greater in patients with psoriasis. IgE concentration is also not associated with the severity of psoriasis based on the PASI score, therefore, the role of IgE in psoriasis can be considered insignificant as some previous studies indicate.
