Skin disorders in women with poor obstetric history: MTHFR polymorphisms and importance of preconceptional counseling

Objectives: This study focused on the link between skin disorders and Methylenetetrahydrofolate reductase (MTHFR) polymorphisms. Methods: Study cases were taken from a pre-conceptional care program where patients with poor obstetric history were evaluated in terms of systemic disorders including skin diseases. This retrospective cohort (n = 472) consisted of 110 (23.3%) and 362 (76.7%) women with or without skin disorders, respectively. For ease of analysis, the history of skin diseases was classified into seven categories: (1) acne/rosacea/other acneiform disorders; (2) fungal disease; (3) pruritis/xerosis; (4) psoriasis vulgaris; (5) acrochordons and other benign skin growths; (6) urticaria/dermatitis; and (7) viral diseases. Results: In this retrospective cohort of 472 women, we explored the impact of MTHFR A1298C and C677T polymorphisms on skin disorders. Despite similar allelic frequencies, our findings revealed a statistically significant association between the presence of MTHFR polymorphisms and skin disorders (p =.027). Subgroup analysis indicated significantly higher rates of MTHFR polymorphisms in patients with psoriasis vulgaris (p =.033) and acrochordons (p =.030), highlighting their potential relevance in specific skin disorder subtypes. Conclusions: The increased prevalence of psoriasis and acrochordons among women with MTHFR deficiency underscores the complex relationship between genetic factors and dermatological health. Our findings emphasized the critical role of MTHFR polymorphisms not only in poor obstetric history but also as significant contributors to skin disorders. This dual association highlights the importance of comprehensive preconception counseling, especially customized for women affected by skin disorders.
