A Study on the Psychological Profile and Coping With the Disease in Patients With Lymphangioleiomyomatosis

Lymphangioleiomyomatosis (LAM) is a rare disease that affects women almost exclusively. We aimed to determine the psychological profile in patients with LAM, and their potential association with sociodemographic and clinical features, and to know their role in coping with the disease.

Cross-sectional and descriptive study in collaboration with the Spanish Association of LAM (AELAM). The variables measured were: socio-demographic, psychological (anxiety, depression, demoralization, spirituality, resilience, social support), clinical (treatment) and health-related quality of life.

We studied 87 LAM patients, with a mean (SD) age of 47.7 (7.7) years, and time since diagnose was 10.1 (5.4) years. 75.9% of patients were receiving sirolimus or everolimus, and oxygen therapy was required in 34.5% of patients. Anxiety was found in 46% of patients, depression in 55%, while only 2% presented demoralization and 14% deficit in spirituality. Social support and resilience were adequate. The "non-severe" group (without oxygen therapy) presented worse results in anxiety. A structural equation model to explore association between variables, showed very adequate fit indices: χ²(14) = 29.743 (p = .074); CFI = .983; TLI = .967; SRMR = .058; RMSEA = .075[.000-.128]. The model identifies resilience, spirituality and social support as "protective factors" from anxiety, depression, and demoralization.

This study performed on a large series of women with LAM describes their psychological profile, in addition to showing how they cope with the disease. We have found that other psychological constructs, such as perceived social support and resilience, are protective factors. Early psychological evaluation and intervention is necessary to reduce comorbidities and prevent mental health problems in women with LAM.
