Dietary patterns and life-styles of patients with gastrointestinal involvement of systemic lupus erythematosus: Questionnaire survey from a tertiary center of China.

OBJECTIVE: To investigate the dietary patterns and lifestyles of patients with lupus gastrointestinal (GI) involvement and to reveal the possible role of organ-specific involvement of systemic lupus erythematosus (SLE) on daily diet. METHODS: Patients with SLE complicated with gastrointestinal involvement (SLE-GI) admitted to Peking Union Medical College Hospital (PUMCH) from January 2010 to September 2021 were enrolled. Age- and sex-matched SLE patients with lupus nephritis (SLE-LN) but free of other internal organs involvement who were admitted during the same period were enrolled as disease controls at the ratio of 1:1. In addition, a group of age- and sex-matched healthy people were also included as healthy controls (HCs). Questionnaires were distributed to these patients and HC to collect their dietary patterns and lifestyle information. Clinical features, dietary and lifestyle habits were compared between the two groups of patients and HC. RESULTS: The questionnaire survey showed that compared with HC, the SLE-GI group had higher proportions of vegetarians (p = 0.014) and a lower proportion of omnivores (p = 0.058). A higher percentage of SLE-GI patients reported a traditional Chinese medicine (p = 0.018) taken history and surgical history (p = 0.014). They also less likely to take fried/pickled food (p = 0.042) and dietary supplements (p = 0.024) than HC. Higher percentages of SLE-GI patients and SLE-LN patients preferred self-catering (87.5% and 94.3%) over take-out food than HC (70.8%) (p = 0.127 and p = 0.016). No significant difference on drinking preference among the three groups, but it seemed more SLE-GI patients consumed yogurt than HC (p = 0.097). The SLE-LN patients were also found to have lower frequencies of staying up late (p = 0.005). The SLE-GI group also presented higher positivity rates for anti-SSA (69.6% vs. 45.7%, p = 0.020) and anti-SSB antibodies (32.6% vs. 10.9%, p = 0.011) but lower positivity rates for anti-dsDNA antibodies (30.4% vs. 82.6%, p < 0.001) compared with the SLE-LN group. CONCLUSION: The dietary patterns, life-styles and autoantibody spectrum of SLE-GI patients differed greatly from those of SLE-LN patients and healthy people. These factors may reflect the influence of disease and organ involvement modes on patients' daily life and may contribute partly to the systemic involvement in SLE.

[Fecal Microbiota Transplantation:Traditional Chinese Medicine Meets Western Medicine].

Fecal microbiota transplantation (FMT) is a therapy of transplanting the functional flora from the feces of a healthy donor into the gastrointestinal tract of a patient to reconstruct the normal flora.The application of FMT in western medicine dates from the 1950s.After decades of development,the efficacy of FMT has been proven in a variety of diseases.The record of FMT in traditional Chinese medicine (TCM) dates early from the 3rd century A.D.,and relevant theories have been recorded in many TCM works in the past dynasties.FMT as a therapy that has been written into guidelines has been accepted by some countries and regions such as the United States and the United Kingdom in the treatment of Clostridium difficile infection,and its clinical indications are expanding.TCM and western medicine,with different medical thoughts,meet in the application of FMT.Exploring a normative and effective FMT procedure reflects not only the patient-centered principle but also the mutual promotion of TCM and western medicine.
