A feasibility study for a triple-blind randomized controlled trial investigating the effects of oral isotretinoin on mood and quality of life in patients with acne vulgaris

Modified red light 5-aminolevulinic acid photodynamic therapy versus low-dose isotretinoin therapy for moderate to severe acne vulgaris: A prospective, randomized, multicenter study

BACKGROUND

Modified 5-aminolevulinic acid photodynamic therapy (M-PDT) and isotretinoin (ISO) are effective treatments for moderate to severe acne vulgaris.

OBJECTIVE

To evaluate the efficacy and adverse effects of M-PDT and ISO for moderate to severe acne vulgaris.

METHODS

A multicenter, randomized clinical trial was conducted with participants randomly assigned to the M-PDT group (up to 5 weekly sessions following manual comedone extraction) or the ISO group (oral ISO, 0.5 mg/kg/d for 6 months) and followed up to 6-months after therapy.

RESULTS

A total of 152 patients were allocated. The overall effective rates in the M-PDT group were significantly higher than the ISO group at 1 month (67.74% vs 10.26%), whereas the opposite was the case 1 month after treatment (75.81% vs 97.44%). Time to achieve 50% lesion improvement in the M-PDT group was significantly less than the ISO group (1 vs 8 weeks). Overall, 70.67% of the ISO group patients experienced systemic side effects such as hepatotoxicity, whereas side effects were skin-limited in the M-PDT group.

LIMITATIONS

Limitations of this study included relatively low numbers of participants and high withdrawal rate.

CONCLUSION

M-PDT offers a more rapid onset of improvement, comparable overall efficacy, good tolerability, and comparable durability of response compared with ISO.

Oral isotretinoin in the treatment of juvenile acne and psychiatric adverse effects - a systematic review

PURPOSE

Acne vulgaris is a very prevalent dermatological condition, especially among adolescents and young adults up to 25 years old, classifying it as juvenile acne. One of the most effective treatments for severe acne is isotretinoin, a derivative of retinoic acid. Despite its high efficacy, this drug has been linked to several side effects including psychiatric adverse alterations, such as anxiety, depression and even suicide. With this systematic review we aim to determine if it is possible to establish a causal relation between oral isotretinoin in the treatment of juvenile acne and the appearance of psychiatric adverse effects.

MATERIALS AND METHODS

We searched two distinct databases, PubMed and Web of Science, and considered the work published between January 2000 and November 2021.

RESULTS

Out of the 599 identified articles, we included 19 studies in this systematic review. Globally, the results we found do not support an association between the use of isotretinoin for acne treatment and mental side effects and the safety of this drug appears to be assured. However, the individual characteristics of each adolescent and their environment should be considered; the personal and family history of mental disorders are pointed out as red flags we should look out for when treating these patients.

CONCLUSION

Despite this being a highly debated topic, especially among the dermatology community, more studies with larger populations and randomised controlled trials are necessary to increase the strength of the evidence presented.

Physiological and Psychological Effects of Isotretinoin in the Treatment of Patients with Acne: A Narrative Review

Isotretinoin (ISO) is a powerful vitamin A derivative that offers the potential for treatment of permanent remission of acne; however, its potential side effects on both physiological and psychological aspects limit its application. This article reviews the side effects of ISO from physiological and psychological aspects in detail, to better screen the suitable population of ISO and improve the efficiency of clinical treatment. Our findings indicate that ISO may cause teratogenicity, skin reactions, ocular reactions, changes in blood indicators, and occasional acne fulminans. To optimize clinical treatment, more attention should be paid to identifying the specific conditions under which these reactions occur, how severe they are, and how they subside to alleviate patient concerns. Regarding the controversial issue of psychological side effects caused by ISO, researchers should shift their focus to the psychological problems that acne itself may cause.

Evaluating Depression Among Acne Vulgaris Patients Treated With Isotretinoin

Background

Isotretinoin is the most effective treatment for moderate to severe acne. However, isotretinoin has many side effects related to its use. Since 1983, when Hetzen reported the first occurrence of new depressive symptoms in patients treated with isotretinoin, a lot of controversies emerged regarding the causal relationship between isotretinoin and depression.

Objective

To evaluate depression among acne patients treated with isotretinoin versus doxycycline at King Fahad Hospital of the University between December 2019-March 2020.

Methods

Using the Global Acne Grading System, patients aged 18 - 30 years old with moderate to severe acne vulgaris who have not received isotretinoin previously and has no personal or family history of any psychiatric illnesses, were evaluated for depression using the patient health questionnaire-9 before starting treatment and 8 weeks after. Twenty-nine patients had met the inclusion criteria and were included in the study.

Results

Of the 29 patients included, 18 patients completed the study (nine males, nine females). Twelve patients received isotretinoin 0.5mg/kg (study group) and six patients received doxycycline 100mg (control group). The mean depression score for the isotretinoin group has decreased from (4 ± 2.48) to (3.08 ± 2.84) but the result was statistically insignificant with a p-value of 0.19, CI (-5.28, 2.36). For the doxycycline group, the mean depression score has decreased from (5.5 ± 2.5) to (2.83 ± 0.75) with a p-value of 0.043, CI (0.12, 5.21). There was no statistically significant difference in the mean depression score between the two groups after 8 weeks of starting treatment [p-valve 0.837, CI (-2.28, 2.78)].

Conclusion

This study showed that, after 8 weeks of starting treatment, isotretinoin at 0.5 mg/kg has no risk of developing depression. The results of this study did not reveal a direct relationship between the use of isotretinoin and the development of depression. Furthermore, optimum control and treatment of acne vulgaris have shown to improve depression scores.

Update in the management of acne in adolescence

PURPOSE OF REVIEW

This review will update the pediatric provider on recent data on the pathogenesis and treatment of acne in adolescent patients. A special focus was made to summarize recent guidelines and fill in several identified practice gaps.

RECENT FINDINGS

Our understanding of the pathogenesis of acne is greatly expanding and data is emerging to tie diet, particularly the role of IGF-1 with inflammation in acne. Additionally, stronger recommendations to limit antibiotic usage in acne are being made worldwide. Although retinoids are considered the base of most effective acne treatment strategies, data suggests that all providers need to emphasize their importance in maintenance of acne.

SUMMARY

An effective acne management strategy targets multiple pathogenic factors in acne, using a retinoid as the foundation. Systemic antibiotics for moderate-to-severe acne should be used for acute management, then discontinued at 3-4 months, while maintaining on topical treatments. If therapy is ineffective, alternate treatments, such as combined oral contraceptives in females or isotretinoin, should be promptly employed to prevent prolonged psychological impact and cutaneous scarring.
