The impact of acne treatment on quality of life and self-esteem: A prospective cohort study from Lebanon

Establishing minimal clinically important differences for the Pemphigus Disease Area Index

BACKGROUND

Pemphigus is a rare autoimmune blistering disease with potentially life-threatening consequences. Establishing minimal clinically important differences (MCIDs) for disease severity scores like the Pemphigus Disease Area Index (PDAI) is crucial for assessing treatment efficacy.

OBJECTIVES

To calculate MCIDs for both improvement and deterioration in PDAI scores in patients with pemphigus vulgaris (PV) and pemphigus foliaceus (PF), using the anchor-based method.

METHODS

A total of 41 patients with pemphigus were recruited, with 35 meeting the MCID analysis criteria. The anchor-based method was used to calculate MCIDs for PDAI scores against the 15-point Likert scale and the Physician Global Assessment visual analogue scale (PGA-VAS) anchors. Receiver operating characteristic curves were employed to determine optimal MCID cutpoints with the highest Youden Index (J). The 15-point Likert scale scores the change in disease severity spanning from -7 to +7, designed to quantify the extent of disease improvement/deterioration since the preceding visit.

RESULTS

The MCID for improvement in PDAI activity scores was 2.65 points using the 15-point Likert scale (78.7% correct classification; sensitivity 75.9%; specificity 73.5%) and 2.5 points using the PGA-VAS as the anchor (78.0% correct classification; sensitivity 84.4%; specificity 68.2%). Given the slightly higher correct classification rate using the 15-point Likert scale anchor, the MCID of 2.65 points was selected for PDAI activity score improvement. In contrast, the MCID for deterioration consistently remained at 2.5 points for the 15-point Likert scale anchor (81.0% correct classification; sensitivity 72.7%; specificity 81.0%) and 2.5 points for the PGA-VAS anchor (70.9% correct classification; sensitivity 69.6%; specificity 76.9%).

CONCLUSIONS

This study marks the inaugural attempt at MCID determination for PDAI scores in pemphigus, filling a critical knowledge gap. The study's calculated MCIDs provide essential benchmarks for clinical trials, treatment evaluation and research design optimization. Future studies should explore international collaborations, to examine potential cross-cultural variations in MCIDs.

Effects of acne severity and acne-related quality of life on depressive symptoms among adolescents and young adults: a cross-sectional study in Bangladesh

INTRODUCTION

Depression is a common mental health disorder and one of the major causes of disability. This study aimed at investigating the relationship of acne severity and acne-related quality of life with depressive symptoms, and the mediating effect of acne-related quality of life in a relationship between acne severity and depressive symptoms.

METHODS

This is a cross-sectional study. Data were collected from acne patients attending a tertiary-level hospital, using a questionnaire that comprised three validated instruments - Investigator's Global Assessment (a single item) scale, Cardiff Acne Disability Index, and Beck Depression Inventory for measuring acne severity, acne-related quality of life, and depressive symptoms, respectively. Logistic regression and linear regression were used to examine the association between acne severity and depressive symptoms and a correlation between the acne-related quality of life and depressive symptoms, respectively. A mediation analysis was also performed to see the mediation effects of acne-related quality of life in a relationship between acne severity and depressive symptoms.

RESULTS

A total of 185 acne patients (155 females, 83.8%) with a mean age was 22.55 ± 8.67 years were included in the study. Adolescents and young adults with severe and moderate acne had 6.14-and 2.28 times higher odds of depression compared to their peers with mild acne, respectively. Patients with low levels of acne-related quality of life had a higher level of depressive symptoms (β = 0.42, p < 0.001). The total effect (direct + indirect) was also significant (β = 0.27, 95% CI: 1.29-4.09), implying the effect of acne severity on depression.

CONCLUSION

The present study suggests that acne severity and acne-related quality of life were associated with depressive symptoms among patients with acne vulgaris. The study also indicates that the relationship between acne severity and depressive symptoms might occur through a chain-mediating effect of acne disability in this population.

Pathways from Trait Emotional Intelligence to factors of distress in Rosacea: The mediating role of Social Phobia and Self-Esteem

BACKGROUND

Rosacea is a skin disease characterized by facial erythema and inflammatory pustules that may result in emotional distress. Social Phobia and Self-Esteem appear to be linked to the development of higher levels of distress in dermatological conditions, while Trait Emotional Intelligence (Trait EI) has been consistently associated with greater levels of adaptation to one's chronic condition. Hence, it seems extremely relevant to observe the interplay between these dimensions in the context of Rosacea. The goal of the current study is to test the hypothesis that an association between Trait EI and General Distress, in individuals with Rosacea would be mediated by Self-Esteem and Social Phobia.

METHODS

Questionnaires were administered to 224 individuals suffering from Rosacea to assess Trait EI, Social Phobia, Self-Esteem, and General Distress.

RESULTS

Results highlighted that Trait EI was positively related to Self-Esteem and negatively related to Social Phobia and General Distress. In addition, both Self-Esteem and Social Phobia showed a mediating role in the relationship between Trait EI and General Distress.

LIMITATIONS

The main limitations of this work consist in the cross-sectional nature of the data, the small number of participants, also it was not possible to differentiate the participants according to the type of rosacea.

DISCUSSION

These results emphasize how individuals with Rosacea may be vulnerable to internalizing states and how high levels of Trait EI may constitute a protective factor for the onset of distressing states and it would be useful to create programs aimed at fostering Trait EI in Rosacea sufferers.

Acne Vulgaris Relapse in Sudanese Patients Treated with Oral Isotretinoin: Rate and Predictive Factors

Purpose

Acne vulgaris is a skin disorder primarily affecting teenagers and young adults. Acne relapse is the main drawback of oral isotretinoin (OI), which is the golden therapy for severe acne. This study aimed to assess the rate and predictive factors of acne relapse among Sudanese patients using OI.

Patients and Methods

A cross-sectional study was conducted in a dermatology and venereology clinic-Sudan, using a self-administered questionnaire and data collection sheet. Patients using OI for acne treatment were enrolled in the study. Chi-square test and logistic regression analysis were used to evaluate the association between variables. P-value <0.05 was considered statistically significant.

Results

225 acne patients (mean age: 26.0±4.2 years, females: 88.9%) were included in this study. OI daily dose ranged from 0.25 to 1 mg/kg/day, with frequent daily doses of 40-49 mg (57.3%) over 3-6 months (81.8%). Around one-third of patients (36%) received maintenance therapy after completion of OI course. At a 2-year follow-up, approximately 36% of patients experienced acne relapse that commonly occurred within 6-18 months after the last OI therapy. Early discontinuation of OI was a positive predictor of acne relapse which was 3.99 times greater in patients who had early discontinued OI than those completing the planned OI course (OR=3.99; p=0.002). OI cumulative doses of 120-139 mg/kg and 140-159 mg/kg were negative predictors of acne relapse (OR=0.23; p=0.001 and OR=0.15; p=0.02, respectively). Most patients (94.2%) received prescription OI, and 76.4% of women were advised to use contraceptives. About 69% of patients practiced skin care.

Conclusion

About one-third of patients experienced acne relapse. Early discontinuation and low cumulative doses of OI are the main risk factors for acne relapse. Long-term therapy of OI, with cumulative doses of 120-159 mg/kg, would be beneficial to reduce acne relapse.

13-cis-Retinoic Acid Affects Brain Perfusion and Function: In Vivo Study

Purpose. Study the effects of 13-cis-retinoic acid (13-RA), a synthetic analogue of a vitamin A used for the treatment of severe acne, on the blood flow in the rat brain using technetium-99m hexamethyl propylene amine oxime (99mTc-HMPAO) imaging. Methods. A total of 30 adult male Wistar rats were divided into the control (C), low-dose (L), and high-dose (H) groups. The L and H rats were exposed subcutaneously to 0.3 and 0.5 mg, respectively, of 13-RA per kg of body weight for seven days. Brain blood flow imaging was performed using a gamma camera. Then, a region of interest (ROI) around the brain (target, T), a whole-body region (WB), and a background region (BG) was selected and delimited. The net 99mTc-HMPAO brain counts were calculated as the net target counts, $\text{NTC}=\left(\text{T}-\text{BG}\right)/\left(\text{WB}-\text{BG}\right)$ in all groups. At the end of the 99mTc-HMPAO brain blood flow imaging, the brain, heart, kidney, lung, and liver were rapidly removed, and their uptake was determined. Brain histopathological analysis was performed using hematoxylin and eosin stains. In addition, the plasma fatty acids were studied using gas chromatography/mass spectrometry. Results. There were highly significant differences between L and H in comparison to C and across the groups. The 99mTc-HMPAO radioactivity in the brain showed increased uptake in a dose-dependent manner. There were also significant changes in the brain tissues and decreased free fatty acids among the groups compared to C. Conclusion. 13-RA increases 99mTcHMPAO brain perfusion, uptake, and function and reduces fatty acids.

Psychological Impact of Acne Vulgaris on the Young Saudi Population

Background

Acne is a chronic inflammatory skin disease caused by bacterial colonization that damages the pilosebaceous gland on the face and other parts of the body. It is one of the most frequent dermatologic diseases in the young population. Acne vulgaris is a devastating disease, and it has a significant impact on a patient's quality of life, influencing their self-esteem as well as their psychosocial development. This study aimed to explore the psychological symptoms associated with patients with acne, its impact on their quality of life according to their personal characteristics, and to raise the importance of observing and managing psychological symptoms during acne treatment.

Methods

In this cross-sectional study, data were collected through a paper questionnaire. The questionnaire was composed of two parts, the first includes data about demographics and general health while the second has details about the Dermatology Life Quality Index (DQLI); the Arabic validated version was used for data collection. Data were analyzed using SPSS version 20 (IBM Corp., Armonk, NY).

Results

According to the impact of acne on respondents' lives, 40.0% have no effect at all, 31.0% have small effects, 19.0% have moderate effects,9.0% have large effects, and 0.7% have extremely large effects.

Conclusions

Acne is a major problem that affects the quality of life of young patients. Its effect is significantly higher among less educated patients and those with a longer duration of disease.
