Acne and risk of mental disorders: A two-sample Mendelian randomization study based on large genome-wide association data

Background

Despite a growing body of evidence that acne impacts mental disorders, the actual causality has not been established for the possible presence of recall bias and confounders in observational studies.

Methods

We performed a two-sample Mendelian randomization (MR) analysis to evaluate the effect of acne on the risk of six common mental disorders, i.e., depression, anxiety, schizophrenia, obsessive–compulsive disorder (OCD), bipolar disorder, and post-traumatic stress disorder (PTSD). We acquired genetic instruments for assessing acne from the largest genome-wide association study (GWAS) of acne (N = 615,396) and collected summary statistics from the largest available GWAS for depression (N = 500,199), anxiety (N = 17,310), schizophrenia (N = 130,644), OCD (N = 9,725), bipolar disorder (N = 413,466), and PTSD (N = 174,659). Next, we performed the two-sample MR analysis using four methods: inverse-variance weighted method, MR-Egger, weighted median, and MR pleiotropy residual sum and outliers. Sensitivity analysis was also performed for heterogeneity and pleiotropy tests.

Results

There was no evidence of a causal impact of acne on the risk of depression [odds ratio (OR): 1.002, p = 0.874], anxiety (OR: 0.961, p = 0.49), OCD (OR: 0.979, p = 0.741), bipolar disorder (OR: 0.972, p = 0.261), and PTSD (OR: 1.054, p = 0.069). Moreover, a mild protective effect of acne against schizophrenia was observed (OR: 0.944; p = 0.033).

Conclusion

The increased prevalence of mental disorders observed in patients with acne in clinical practice was caused by modifiable factors, and was not a direct outcome of acne. Therefore, strategies targeting the elimination of potential factors and minimization of the occurrence of adverse mental events in acne should be implemented.

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.

The course of acne in healthcare workers during the COVID-19 pandemic and evaluation of possible risk factors

BACKGROUND

There are a limited number of publications reporting an increase in acne in the COVID-19 outbreak.

OBJECTIVE

The study aimed to evaluate the course and the clinical features of acne and possible risk factors during the COVID-19 pandemic in healthcare workers.

METHOD

A total of 172 physicians (female, n = 159, male; n = 13, mean age = 35.03 ± 5.27 years) who had acne in any period of their life were included in the study. A self-administered online questionnaire was applied.

RESULTS

During the COVID-19 pandemic, 45.35% of the participants reported that their acne complaints increased, 27.33% reported relapses, and 7.56% reported occurrence for the first time. Newly formed acne was reported most frequently on the chin (78.26%). The number of female participants, smoking, increased stress, and the rate of surgical mask use were found to be higher in the group whose acne occurred for the first time, relapsed, or increased than in the group whose acne complaints were unchanged or decreased (p < 0.05). In the group whose acne relapsed or increased, adult-onset acne, presence of scar, and use of systemic acne treatment before the COVID-19 pandemic were more common than in the group whose acne complaints were unchanged or decreased (p < 0.05).

CONCLUSION

Almost half of the participants reported an increase in acne. More than a third of the participants reported that their acne relapsed or they had acne for the first time. In addition to the use of surgical masks, factors such as increased stress, smoking, adult-onset acne, presence of scar, and previous systemic acne treatment were found to be responsible for acne development.

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

Background

Acne is highly prevalent among teenagers and young adults, with proven negative psychological and emotional impact. To our knowledge, no study has been conducted to quantify the repercussions of acne on quality of life (QoL) and self-esteem in Lebanon.

Objective

This study aimed to highlight the effect of acne treatment on QoL and self-esteem of Lebanese adolescents and young adults.

Methods

In this observational prospective study, patients between 15 and 40 years old with moderate-to-severe acne were allocated to one of two treatment groups (isotretinoin vs. systemic antibiotics combined with topical treatments) and followed for a period of 6 months. The effect of acne on QoL was measured using the Dermatology Life Quality Index, Cardiff Acne Disability Index, and Rosenberg Self-esteem Scale before treatment initiation (T1), after 3 months (T2), and after 6 months (T3). A multivariate analysis of covariance model was used.

Results

Sixty-two patients were included, of whom 79% were female and 61.3% had moderate acne. Fifty-five percent of patients were treated with systemic antibiotics combined with topical treatments, and 45% received isotretinoin. Mean scores of Cardiff Acne Disability Index, Dermatology Life Quality Index, and Rosenberg Self-esteem Scale at T1 were comparable between the two groups. A significant improvement was noticed in both groups at T2 and T3. The multivariate analysis of covariance model showed an interaction of time and age that concerned 25- to 40-year-old patients in both groups, who were the most negatively affected by acne at T1 and improved the most at T3.

Conclusion

This study demonstrated the equivalence between acne treatments in improving QoL and revealed the social obstacle that acne creates and its recrudescence in the subgroup of women of childbearing age.

Comparison of the psychosocial impact of acne in adolescents and adults; body satisfaction, self-esteem, and quality of life

BACKGROUND

Dermatological diseases, including acne vulgaris, have significant psychosocial effects on patients.

AIMS

To compare body satisfaction, self-esteem, and quality of life (QoL) in adolescents and adults with acne.

METHODS

A total of 192 acne patients (132 female, 60 male; aged 19.42 ± 3.50 years) were included in the study. Global Acne Grading System, Rosenberg Self-Esteem Scale (RSES), Turkish Acne Quality of Life Index (TAQoLI), and Body Cathexis Scale (BCS) were used. The patients were divided into two groups: under 20 years old (adolescents) and 20 years and above (adults).

RESULTS

The mean RSES score was found as 19.49 ± 5.11, the mean BCS score was 143.95 ± 20.92 and the mean TAQoLI score was 23.44 ± 10.02. There was no difference between adolescents and adults in terms of the mean value of the RSES score, TAQoLI score, and BCS score (p > 0.05). But, the proportion of those whose RSES score is below 15 is higher in patients under 20 years of age (28%) than patients aged 20 and over (14%) (p < 0.05). Linear regression analysis revealed that the most important determinant of body satisfaction was self-esteem (β = 0.287, p < 0.05), the most important determinants of self-esteem were body satisfaction (β = 0.208, p < 0.05), QoL (β = -0.398, p < 0.001), and education level (β = 0.245, p = 0.007) and, one of the most important determinant of QoL was self-esteem (β = -0.403, p < 0.001).

CONCLUSIONS

This study demonstrates that acne vulgaris negatively affects an individual's body satisfaction, self-esteem, and QoL. The psychosocial burden of acne is as significant for adults as for adolescents. Body satisfaction, self-esteem, and QoL are in interaction with each other.

Acne in the first three decades of life: An update of a disorder with profound implications for all decades of life

Acne vulgaris is a chronic, inflammatory, skin condition that involves the pilosebaceous follicles and is influenced by a variety of factors including genetics, androgen-stimulation of sebaceous glands with abnormal keratinization, colonization with Cutibacterium acnes (previously called Propionibacterium acnes), and pathological immune response to inflammation. Acne can occur at all ages and this discussion focuses on the first three decades of life. Conditions that are part of the differential diagnosis and/or are co-morbid with acne vulgaris are also considered. Acne in the first year of life includes neonatal acne (acne neonatorum) that presents in the first four weeks of life and infantile acne that usually presents between 3 and 6 months of the first year of life with a range of 3 to 16 months after birth. Acne rosacea is a chronic, inflammatory, skin condition that is distinct from acne vulgaris, typically presents in adults, and has four main types: erythemato-telangiectatic, papulopustular, phymatous and ocular. Treatment options for acne vulgaris include topical retinoids, topical benzoyl peroxide, antibiotics (topical, oral), oral contraceptive pills, isotretinoin, and others. Management must consider the increasing impact of antibiotic resistance in the 21st century. Psychological impact of acne can be quite severe and treatment of acne includes awareness of the potential emotional toll this disease may bring to the person with acne as well as assiduous attention to known side effects of various anti-acne medications (topical and systemic). Efforts should be directed at preventing acne-caused scars and depigmentation on the skin as well as emotional scars within the person suffering from acne.
