ABSTRACT
Introduction Acne vulgaris is a dermatologic condition that affects the pilosebaceous unit. It is the most common skin disorder worldwide, and it is most prevalent during puberty. For patients with moderate to severe acne that is unresponsive to antibiotic treatment, the main treatment is oral isotretinoin. The objective of this study was to define the impact of isotretinoin and its well-established adverse effects on the psychological status of acne patients during treatment. Methods The sample cohort included 80 patients with acne vulgaris who were treated with isotretinoin. The sample size was calculated using the Raosoft [Raosoft.com (2015) Sample Size Calculator by Raosoft, Inc.] sample size calculator to maintain a confidence interval of 95% and a margin of error of 5%. The participants were assessed using the Depression and Anxiety Stress Scale-21 (DASS-21). The DASS-21 is a self-reporting scale used to measure the emotional states of depression, anxiety, and stress. This study was a cross-sectional survey conducted at the dermatology outpatient clinic at King Abdulaziz Medical City, Jeddah, Saudi Arabia. All patients diagnosed with acne vulgaris between January and April 2020 were included in the study. A multivariate regression analysis was also conducted to determine the presence of any significant independent factors associated with depression, anxiety, and stress. A P-value of ≤0.05 was considered statistically significant. Results We observed that the most prevalent psychiatric disorder among acne patients on isotretinoin therapy was anxiety. Our results also indicate that a history of mental illness is an independent risk factor for developing depression when isotretinoin is used. In addition, known adverse physical effects of isotretinoin treatment, including muscle pain, arthralgia, and headaches significantly increase the likelihood of patients developing psychiatric morbidity during therapy. Conclusion Isotretinoin is a highly potent therapy for acne. Overall, the physical side effects profile is well acknowledged, yet the exact psychological impact the treatment predisposes the patients to is yet to be determined.
ABSTRACT
Multiple sclerosis (MS) is a chronic neurodegenerative disease that affects the central nervous system. Familial MS is arbitrarily defined as a type of MS that runs in families with 1 or more first- to third-degree relatives in addition to the index case affected by MS. The aim of this article is to report a unique case of familial MS from Saudi Arabia with 2 novel variants in the HLA-DRB1 gene that may contribute to the pathogenesis. We observed an unfavorable response to interferon therapy and successful treatment using fingolimod therapy. This observation needs further study, including whether this lack of response is specific to interferon treatment or possibly a chance occurrence. This family work-up illustrates the importance of genetic testing in identifying variants associated with familial MS, especially if more than 2 members of the same family are affected. Although this genetic tool is used mainly for research purposes, it had clinical implications for our patient, including the appropriate selection of disease-modifying therapy and prognostic counseling. Further large-scale studies are needed to expand the genetic spectrum of familial MS with clinical and pharmacologic correlation.
