Management strategies for acne vulgaris

The increasing importance of the gut microbiome in acne vulgaris

Acne is a frequently presented dermatological condition brought about by an interplay among inflammation, increased sebum production, hyperkeratinisation, and predominantly Propionibacterium acnes (renamed as Cutibacterium acnes) proliferation, leading to debilitating psychological scars. However, it has been shown that it is the loss of microbial diversity in the skin and the imbalance among C. acnes phylotypes that brings about acne rather than the C. acnes species as a whole. Interestingly, recent evidence suggests that other microorganisms may be implicated, such as the fungi Malassezia and the bacteria Cutibacterium granulosum. A plethora of scientific evidence suggests that the gut microbiome is implicated in the overall health and physiology of the host; studies show that the gut microbiome of acne patients is distinct and depicts less microbial diversity compared to individuals without acne. Herein, using the key terms: acne, C. acnes, IGF-1, sebum, and gut microbiome, we carried out a review of the literature, using Google Scholar and PubMed, and discussed the role of the gut and skin microbiome in relation to acne, as a narrative review. The role of hormones, diet, sebum, and stress in relation to the gut microbiome was also investigated. Therapeutic implications and the use of pre-/postbiotics are also deliberated upon. In this light, future research should investigate the relationship between the gut microbiome and the agreed upon factors of acne pathology, potentially leading to the discovery of novel acne treatments with milder side effects.

Efficacy and tolerability of system isotretinoin and effect of this therapy on the quality of life of patients with severe and moderate acne

Background. The relationship between acne and depression is being actively studied by the medical community. Question is depression a restriction in prescribing or a side effect when using systemic isotretinoin remains controversial. Noteworthy is the presence in the scientific literature of data on the possible positive effect of adequately and timely prescribed acne therapy on the psychoemotional state of patients with this ailment. Aims. The aim of our study was to evaluate the effectiveness of therapy with systemic isotretinoin in patients with moderate and severe acne, to assess the effect of the therapy on the quality of life of patients, as well as the persistence of remission after the end of the course of therapy with systemic retinoid. Methods. We observed 32 patients with moderate and severe acne, the average age of patients was 24 years, the duration of the disease was on average 8 years. All patients underwent therapy with systemic isotretinoin (Sotret) at an average daily dose of 0.51.0 mg/kg until a cumulative dose of 120150 mg/kg was reached. The effectiveness and tolerability of the therapy was assessed, as well as the quality of life of patients was assessed using the dermatological index of the quality of life (DQL), the dermatological akne index (DIA), the HADS scale (anxiety and depression scale). The indicators were assessed before the start of therapy, during therapy, at the end of the course of treatment with systemic isotretinoin, and also 12 months after the end of therapy. Results. 100% of patients achieved clinical remission as a result of treatment with systemic isotretinoin. Before starting therapy with systemic isotretinoin, the indices were as follows: DQL 18 (1520), HADS 10 (716) and DIA 13 (615) scores. By the end of the therapy, the indices decreased to 1 (01), 2 (04) and 1 (01) points, respectively (p 0.001). 12 months (year) after the end of therapy with systemic isotretinoin, the indices remained at zero or one level in all patients: DQL 1 (01), HADS 0 (01) and CIA 1 (01) points (p 0.001). Conclusion. A causal relationship between the intake of systemic isotretinoin and the development of depression has not been established. Systemic isotretinoin therapy was effective in all patients (100%), was well tolerated and had a positive effect on the psychoemotional status of patients with acne. 12 months after the end of therapy with the drug Erase, stable remission of the disease was noted in all patients

Efficacy of local application of an Unani formulation in acne vulgaris

Background and Objectives:

Buthūr-i-Labaniyya (Acne vulgaris) is affecting up to 80% of adolescents and many adults at different stages of life. It is one of the commonest skin disorders which appears on cheeks and nose as white eruptions that seems like solidified milk drops. These eruptions are treated by drugs having properties of tajfīf wa taḥlīl (desiccant and resolving), as mentioned by Ibne Sina. Daood Antaki in his book Tazkira Oolulalbab recommends the local application of a paste of Shonīz (nigella sativa), Naushādar (ammonium chloride) and Būra Armani mixed with Sirka (vinegar) for effective treatment of Acne vulgaris.

Methods:

The study was observational self comparison before and after treatment, conducted in the OPD of the hospital which is part of the National Institute of Unani Medicine, Bangalore. The duration of study was one year. 40 Female patients with combination of comedones, papules, pustules and nodules were recruited for this purpose. The test drug, Shonīz, Būra Armani, Naushadar powder, mixed with sirka were applied locally for one month with taqlīl-i-ghidhā tadābīr (low calorie index diet). All subjects were assessed on the basis of changes in subjective and objective parameters.

Results:

The response of test drugs was statistically highly significant (P < 0.01) by using ANOVA repeated measure test, there was also relief in subjective parameters. Subjects reported a reduction of 82.6%, 80.9%, 66.6% in tenderness, itching and irritation respectively.

Interpretation and Conclusion:

The present study reveals that the test drug formulation is safe and effective in treating Acne vulgaris if used along with low calorie index diet. No side effects of drugs were reported, therefore the trial formulation can be recommended to manage Acne vulgaris of mild to severe degree as a therapy.

Acne vulgaris

Acne vulgaris is a chronic inflammatory disease of the pilosebaceous unit and it is observed equally in both sexes and nearly all races. It generally begins at puberty, but the healing period is variable. There is no known etiological factor, except genetic tendency. Androgens play a very limited role in some female patients. The effects of cosmetics, foods and drinks are also discussible and too limited. There are four factors in acne pathogenesis: Increase of the sebum excretionKeratinization of infrainfundibulumBacterial colonization of the follicleInflammation It is mainly observed on the face and back, shoulders and chest. Initial lesions are comedons. Papules, pustules and cysts of severe types follow it. The most important factor in treatment is a very good patient-physician communication. Topical or systemic treatment or both can be used depending on the severity of acne. Benzoyl peroxyde, azelaic acid, AHA's antibiotics, retinoic acid and derivatives are the topical choices. For systemic treatment antibiotics are the most commonly used medicines, but isotretinoine has a very spesific place with the possibility of permanent healing. All kind of treatments need approximately six months for a good result.

Evaluation of biophysical skin parameters and assessment of hair growth in patients with acne treated with isotretinoin

INTRODUCTION

Treatment of the severe forms of acne vulgaris remains a challenge. Isotretinoin is a drug often used in these cases. Retinoids affect the mechanisms that play a role in the pathogenesis of acne, reduce the production of sebum and sizes of the sebaceous glands. However, isotretinoin appears to have undesirable side effects in the skin, mucous membranes and hair.

AIM

THE AIM OF THIS STUDY WAS TO ASSESS THE EFFECT OF ACNE VULGARIS TREATMENT WITH ISOTRETINOIN ON BIOPHYSICAL SKIN PARAMETERS: skin sebum and stratum corneum hydration levels, transepidermal water loss values, pH, erythema and hair growth parameters: total number, density and proportion of anagen hair.

MATERIAL AND METHODS

THE STUDY INCLUDED THIRTY PATIENTS WITH ACNE TYPES: papulopustular, conglobata and phlegmonosa. Patients were treated with isotretinoin at a dose of 0.5-1.0 mg/kg/day for a period of 4-7 months. The measurements of skin biophysical parameters were performed before and after the treatment using Sebumeter SM815, Corneometer CM825, Tewameter TM300, MX Mexameter MX18 and Skin-pH-Meter PH908. Hair growth parameters were evaluated with FotoFinder Dermoscope using the TrichoScan Professional V3.0.8.76 software.

RESULTS

The results of biophysical skin parameter measurements after the treatment showed a reduction in the severity of seborrhea. However, the skin was dry, which confirmed a lowered degree of stratum corneum hydration and an increase in transepidermal water loss values. Moreover, severity of erythema, an increase in pH value, and variations in selected hair growth parameters: decrease in total count, density and proportion of anagen hair were demonstrated.

CONCLUSIONS

The reduction in the skin sebum levels was observed after the treatment. There was dryness of the skin, which was confirmed by biophysical skin parameter measurements. Changes in the hair growth parameters showed telogen effluvium hair loss.
