Isotretinoín y depresión: ¿una realidad?

Does isotretinoin therapy of acne cure or cause depression?

Cosmetic defects in acne may provoke a wide range of mental disorders (depressive, social-phobic, etc.). Isotretinoin is a very effective acne treatment; hence, it usually resolves the associated mental disorders. However, more available data show the possible association of taking isotretinoin and the onset of a depressive syndrome that includes frank depression and even suicidal ideation. The frequency of depressive disorders during isotretinoin treatment varies from 1% to 11% in different studies, and it is unclear whether this is a consequence of isotretinoin therapy. Since it crosses the blood-brain barrier, isotretinoin affects the expression of a broad spectrum of genes in the limbic structures, thus affecting the function of the dopaminergic, serotonergic, and noradrenergic neurons involved in the regulation of mood and emotion. It was suggested that isotretinoin in high concentrations inhibits hippocampal neurogenesis and induces apoptosis of hippocampal cells. However, some studies do not confirm this pathogenic role, and isotretinoin was even reported to have a therapeutic effect in acne-associated depression. In this review, we highlight epidemiological data, the underlying molecular pathogenesis, and the aspects of prevention concerning retinoid-induced depression in acne from the practical point of view of a dermatologist.

Comparison of depression, anxiety and life quality in acne vulgaris patients who were treated with either isotretinoin or topical agents

BACKGROUND

Since the introduction of isotretinoin to the market, many adverse psychiatric effects, including depression, anxiety and suicide attempts were reported. The aim of this study was to determine whether patients with acne who were treated with isotretinoin experienced significant increases in psychiatric symptoms over a 4-month period compared with patients who received topical acne therapy.

METHODS

Seventy-eight acne patients were allocated either to isotretinoin treatment (study group) (n = 37) or to topical treatment (control group) (n = 41). Their psychological status was evaluated at the baseline, second and fourth months of the treatment. All patients were required to complete the dermatology life quality index (DLQI), the Hospital anxiety and depression (HAD) scale, and the beck depression inventory (BDI).

RESULTS

The two groups were not different from each other in terms of DLQI, BDI, HAD-A, HAD-D and total HAD scores at baseline. However, at the end of the second month quality of life was more impaired in the topical treatment group compared to the isotretinoin group (P < 0.05), and there were no difference between two groups in terms of BDI, HAD-A, HAD-D, and total HAD scores (P > 0.05). At the end of fourth month quality of life and all psychological test scores had improved more in the isotretinoin group compared to topical treatment group (P < 0.05).

CONCLUSION

Results of the present study indicate that there is no increase in depressive and anxiety symptoms in the isotretinoin treatment group compared to that in the topical group. Instead, successful treatment of acne seems to improve both depressive and anxiety symptoms and improve quality of life.

Depression and suicidal behavior in acne patients treated with isotretinoin: a systematic review

Isotretinoin (13-cis retinoic acid) is an effective treatment for severe cystic or recalcitrant acne vulgaris; however, concerns have been raised regarding its potential association with depression and suicidal behavior. We sought to explore the proposed relationship between isotretinoin use and the risk of depression and attempted and completed suicide in patients with acne vulgaris by performing a systematic literature search for studies reporting primary data on depression and suicidal behavior in patients treated with isotretinoin for acne vulgaris. Nine studies met the qualifying criteria for our analysis. Rates of depression among isotretinoin users ranged from 1% to 11% across studies, with similar rates in oral antibiotic control groups. Overall, studies comparing depression before and after treatment did not show a statistically significant increase in depression diagnoses or depressive symptoms. Some, in fact, demonstrated a trend toward fewer or less severe depressive symptoms after isotretinoin therapy. This decrease was particularly evident in patients with pretreatment scores in the moderate or clinical depression range. No correlation between isotretinoin use and suicidal behavior was reported, although only one retrospective study presented data on this topic. Although the current literature does not support a causative association between isotretinoin use and depression, there are important limitations to many of the studies. The available data on suicidal behavior during isotretinoin treatment are insufficient to establish a meaningful causative association.
