Abstract

The objective: To identify, review and compare the pathological acne and the connection between other gynecological diseases in women of different ethnic groups.

Methods and materials: This study was carried out based on the World Health Organization database, hospital based acne incidence, different research materials and official websites of medical committees.

Results: After analyzing the materials for 20 years, one in ten (7-17%) of people having acne after the age of twenty five. Women are far more likely to have acne during their early adult years than men, with more than eight in ten of cases of adult acne occurring in women. Clinical acne was more prevalence in African American (37%) and Hispanic women (32%) than in Continental Indian (23%), Caucasian (24%) and Asian women (30%).Among the women with acne 37.3% of women were diagnosed with polycystic ovarian syndrome where as 39.2% with abnormal menstruation. Other percentage of women diagnosed with premenstrual dysphoric disorder and other gynecological disorders.

Conclusion: Many causes of adult acne are due to changes in hormone levels that women experience at certain points during their lives such as before menstrual periods, during pregnancy, starting or stopping birth control pills and polycystic ovarian syndrome and their prevalence percentage depend on their nationality. Importantly, public health initiatives that improve acne associated with gynecological diseases awareness address amenable risk factors and allow for the early detection will be essential in addressing the outcome inequalities that currently exist.

Introduction

Acne is the most common type of inflammatory dermatological disease widespread among any age from newborn to menopause .Peak incidence of acne (59% to 95%) occurs in adolescent girls aged between 15-16. After 25 years the frequency of acne decreases up to 25%.1,2 Acne is thought to be caused by changes in hormones that are triggered during puberty and frequency of occurrence doesn’t depend on gender. But women of secondary reproductive age suffer more from acne than men. Psychological stress, diet, smoking, genetic predisposition and hormonal disbalance have been considered as factors that can trigger or worsen acne. Research studies have shown that there is a direct relationship of acne with hormonal disbalance and gynecological diseases.3

Can stress exacerbate acne?

There is increasing evidence that psychological stress is an important factor in acne pathogenesis. Emotional stress associated with the production of hormones, neuro peptides, and inflammatory cytokines influences the chronic course and exacerbation of acne by altering the activity of the pilosebaceous unit. These mechanisms involve the HPA axis and the neuro-immuno-cutaneous system where neuropeptides and hormones such as CRH and melanocortins play a substantial role.4 Stress signals initiate the hypothalamic pituitary adrenal (HPA) axis and the sympathetic nervous system, while also inducing secretion of different neurotransmitters, cytokines, and hormones that possess skin receptors and can aggravate several skin diseases, including acne.5,6 The corticotrophin-releasing hormone (CRH) appears to be an important aspect in the development of acne lesions.7,8 Many patients report that emotional stress makes their acne worse, and these statements were confirmed in several studies by a significant percentage of affected adolescents and adults (varying between 50-80%).9 An Australian survey that included 215 graduating medical students, reported that 67% of them identified stress as one of the factors leading to acne exacerbations.10 Two Korean epidemiological studies found psychological stress to be the main triggering or aggravating factor influencing acne as reported by the majority (80-82%) of patients (Figure 1).9

The effects of smoking on acne

Smoking has negative effect on human body including acne. Some studies prove that nicotine has an anti-inflammatory action on acne.11 According to recent studies it showed that smokers have higher affinity to acne and there is a relationship between smoking and non-inflammatory acne.12 Smoking produce free radicals it stimulate body to produce cytokines.13

Studies have shown that cytokine levels are high in clogged pores and when healthy skin is exposed to high levels of cytokines; it starts to develop acne.14 Smoking leads to the reduction of estrogen levels in the body and it leads to ovarian malfunction, irregular menstruation. According to the researches smoking has less effect on changing testosterone levels in the body.15

Relationship between acne and hormone levels

Hormones are an important factor in acne development, particularly androgens, which are present in both males and females. Higher levels of androgens tend to lead to acne. While it is not known exactly how hormones affect acne, we do know that the skin is a target for hormones and can even produce hormones itself.16 Higher levels of estrogens normally correlate with fewer acne symptoms (Figure 2).

Effects of food on acne

Dairy products

Milk contains insulin-like growth factor (IGF-1). Higher levels of IGF-1 lead to higher production of skin oil. Higher production of skin oil because more prevalence of acne, researchers states that insulin-like growth factor in milk increased skin oil production and cause higher production of acne. Milk contains androgen precursors. These precursors require enzymes to convert them into actual male hormones in the body, and these enzymes are readily available in the pores of the skin.17

Chocolate

There is a correlation between chocolate and increased insulin levels. Higher levels of insulin lead to higher incidence of acne symptoms by increasing skin cell production. It cause increased skin oil (sebum) production and clogged pores which provide suitable environment for acne bacteria. Chocolate consists of antioxidants, which might theoretically help to reduce acne symptoms. Dark chocolate leads to the lowering of blood pressure which may lead to increase oxygen and nutrient distribution to dermis and help to relieve acne associated symptoms.18

Fatty acid/oil

According to researches fatty diets lead higher fat content in sebum. Omega-3s are known to improve mood and reduce stress and anxiety. Since there is a correlation between stress and acne omega-3 fats could help in reduction of acne symptoms.19

Acne-associated syndromes

Acne-associated syndromes prove the nature of these diseases and are indicative of pathogenesis of acne. Polycystic ovary (PCOS), synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO), hyperandrogenism-insulin resistance-acanthosis nigricans (HAIR-AN), pyogenic arthritis-pyoderma gangrenosum-acne (PAPA), pyoderma gangrenosum-acne vulgaris-hidradenitis suppurativa-ankylosing spondylitis (PASS), pyoderma gangrenosum-acne conglobate-hidradenitis suppurativa (PASH), seborrhea-acne-hirsutism-androgenic alopecia (SAHA), and Apert syndromes are well known acne associated syndromes. Endocrine disorders (insulin resistance, obesity, hyperandrogenism, etc.) can be commonly seen in this syndromes.20

Polycystic ovary syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is an ovarian disease characterized by hyperandrogenism, chronic anovulation, and polycystic ovaries. It is one of the most common endocrinopathy that affects 4–12% of women of reproductive age.21 The pulse frequency of gonadotropin-releasing hormone (GnRH) increases in PCOS and stimulates to the anterior pituitary gland to secrete luteinizing hormone (LH) more than follicle-stimulating hormone (FSH), resulting in an increased ratio of LH to FSH. Studies have shown that disruption of production and the ratio of gonadotropic hormones (FSH and LH) found in 23.9% of patients with acne.3 The increase in LH relative to FSH stimulates the ovarian theca cells to synthesize androstenedione. Consequently, the net ovarian androgen production increases.6 Insulin has also a role in the pathogenesis of PCOS by stimulating the ovarian theca cell to secrete androgens as LH and also inhibits hepatic production of sex hormone binding globulin (SHBG). As a result, free and total androgen level increases. Insulin resistance and hyperandrogenism are responsible for the cutaneous involvement of PCOS. Insulin resistance causes acanthosis nigricans (AN), and hyperandrogenism leads to hirsutism, acne, oily skin, seborrhea, and hair loss (androgenic alopecia). It is estimated that 72–82% of women with PCOS have cutaneous signs.22 PCOS has also multisystem effects and is associated with lots of diseases including infertility, endometrial cancer, obesity, depression, sleep-disordered breathing/obstructive sleep apnea (OSA), nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH), type 2 diabetes mellitus (T2DM), and cardiovascular diseases.23 Although acne, hirsutism, and were the most common skin manifestations, hirsutism and were the most sensitive for PCOS diagnosis. According to research reports 32.8% patients with acne got PCOS.3

Hyperandrogenism-insulin resistance-acanthosis nigricans syndrome (HAIR-AN syndrome)

Hyperandrogenism-insulin resistance-acanthosis nigricans syndrome (HAIR-AN syndrome) is a subphenotype of polycystic ovary syndrome. It is clinically characterized by acne, obesity, hirsutism, and acanthosis nigricans. It usually manifests in early adolescence. Genetic, environmental factors, and obesity are estimated to cause HAIR-AN syndrome.24 Adolescents with HAIR-AN syndrome usually have normal levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) but the ratio of LH to FHS is usually more than one.25 Polycystic ovary syndrome (71–86%), congenital hyperplasia of the adrenal (3–10%), adrenal and ovarian tumors (0.3%), and idiopathic hirsutism (10%) are, respectively, the most common reasons of hyperandrogenism. Except those, HAIR-AN syndrome is a reason of hyperandrogenism that is seen in almost 5% of females with hyperandrogenism.26

SAHA syndrome (seborrhea-acne-hirsutism-androgenic alopecia)

The SAHA syndrome is classified into four types: idiopathic, ovarian, adrenal, and hyperprolactinemic, and it can be associated with polycystic ovaries, cystic mastitis, obesity, insulin resistance, and infertility.27 In the pathogenesis of SAHA, increased androgen synthesis in adrenals and ovaries, disturbed peripheral metabolism of androgens or induction of metabolism and activation of androgens in the skin may play important role. Approximately 20% of the patients have all four major signs of SAHA syndrome. Seborrhoea is observed in all of patients, androgenetic alopecia is seen in 21% of the patients, and acne in 10% and hirsutism in 6% of the patients.28

Prevalence of acne in multiethnic woman

Asian women showed slightly lower acne incidence compared to African American or Hispanic women, but slightly higher compared to Caucasians and Indians. Asian women had the lowest amount of non-inflammatory blackheads and whiteheads, than any other ethnicity but they had the highest amount of inflammatory acne.29 Black skin woman mostly has inflammatory acne nodules and cysts.30

Based on the Journal of the European Academy of Dermatology and Venereology 2011 clinical acne was more prevalent in African American and Hispanic women (37%, 32% respectively) than in Continental Indian, Caucasian and Asian (23%, 24%, 30% respectively) women. All racial groups displayed equal prevalence of both subtypes of acne with the exception of Asians, for whom inflammatory acne was more prevalent than comedonal (20% vs. 10%) acne, and in Caucasians, for whom comedonal acne was more prevalent than inflammatory (14% vs. 10%) acne. Hyper pigmentation was more prevalent in African American and Hispanic (65%, 48% respectively) than in Asian, Continental Indian and Caucasian (18%, 10%, and 25% respectively) women.31,32–40

Conclusion

Their lives before menstrual periods, during pregnancy, starting or stopping birth control pills, polycystic ovarian syndrome, hyperandrogenism-insulin resistance-acanthosis nigricans (HAIR-AN), seborrhea-acne-hirsutism-androgenic alopecia (SAHA).

When considering the Acne in different ethnic groups genetic predisposing factors for androgen receptors is highest in Black African woman, lowest in White Caucasian woman and moderate in Asian woman.

Black skin is tougher than white skin and is less sensitive towards many factors, such as sunlight. Prevalence of acne in black skin is more than in white skin. White skin is generally more sensitive and it is not that rough and tough and the acne on white skin is more visible and clear than any other skin color. Acne is more prevalent in white skin due to several genetic factors and their life style modification.

Healthy food consumption and healthy life style, early screening for gynecological diseases, early treatment for hormonal disbalance, proper contraception methods will help to reduce the prevalence of acne related gynecological diseases in woman.
