Importance: Connective tissue disorders are proposed in the literature to be predisposing risk factors for pelvic floor disorders. Prior data characterizing the prevalence of and symptom burden related to pelvic floor disorders are limited for individuals with Marfan syndrome and are nonexistent for those with Loeys-Dietz syndrome.
Objective: The objective of this study was to determine the prevalence and severity of symptoms related to pelvic floor disorders among individuals with Marfan syndrome and Loeys-Dietz syndrome using the Pelvic Floor Distress Inventory-20 (PFDI-20).
Study design: In this cross-sectional study, a survey including the PFDI-20 was administered to biologically female individuals older than 18 years with a confirmed diagnosis of Marfan syndrome or Loeys-Dietz Syndrome. Respondents were solicited through the websites, email lists, and social media forums of The Marfan Foundation and The Loeys-Dietz syndrome Foundation.
Results: A total of 286 respondents were included in the final analysis, 213 with Marfan syndrome and 73 with Loeys-Dietz syndrome. The median PFDI-20 score of the cohort was 43.8. Individuals with Loeys-Dietz syndrome had higher PFDI-20 scores and were more likely to have established risk factors for pelvic floor disorders that correlated with their PFDI-20 scores compared with those with Marfan syndrome.
Conclusions: Respondents with Marfan syndrome and Loeys-Dietz syndrome experience a high burden of symptoms related to pelvic floor disorders. Despite the similar pathophysiology and clinical manifestations of these disorders, there were differences in PFDI-20 responses that may suggest that these diseases differ in the ways they affect the pelvic floor.
