Introduc0on: Multiple Chemical Sensitivity (MCS) is a chronic illness characterized by the appearance of a wide variety of symptoms secondary to exposure to chemicals present in the environment at concentrations well tolerated by the general population. It is a disease with a low prevalence for which the pathophysiological mechanism is unknown. The presence of avoidant behaviors has been observed in these patients in response to substances that trigger symptoms, including various foods, which could have an impact on the nutritional status of these patients. Objectives: The main objective of this study is to determine the nutritional status of patients with MCS aqended and followed up in outpatient clinics by Internal Medicine at San Juan University Hospital. As secondary objectives, sarcopenia will be assessed through dynamometry, changes in CONUT score from the initial assessment to the present moment will be compared, and the BMI of patients with MCS will be described. Hypothesis: MCS results in a state of malnutrition in patients suffering from this illness. Material and methods: This is an observational, descriptive, retrospective study of a sample of 10 patients with MCS who consented to participate in the initial blood test at the first outpaWent evaluation (baseline blood test) and continued follow-up (last blood test performed), to establish changes in nutritional status that may occur following adaptive food avoidance behaviors. Recruitment was consecutive. Analytical data were collected through the Orion system and through direct interviews with patients with dynamometry, weight, and height measurements. PubMed and UpToDate databases were used as research engines for the literature search. SPSS v 27.0 sotware was used for statistical analysis. Results: 4 (40%) patients were found to have a normal nutritional status, 5 (50%) were at risk of malnutrition, and only 1 (10%) had malnutrition. The sample consisted of 2 men (20%) and 8 women (80%), with an average age of 60.5 years. Regarding comorbidiWes, 7 (70%) had anxiety and 6 (60%) fibromyalgia. According to the body mass index (BMI), 1 (10%) paWent was underweight, 3 (30%) had a normal weight, 5 (50%) were overweight, and 1 (10%) was obese. The MUST scale was also applied for malnutrition screening: 6 (60%) patients were at low risk, 2 (20%) at intermediate risk, and 2 (20%) at high risk. With the CONUT index, scores indicating normal nutrition were observed in 9 (90%) patients. As for sarcopenia, according to the SARC-F questionnaire, 8 (80%) had a normal score, and 2 (20%) had a positive screening. Grip strength was measured by dynamometry, where cutoff points for dynapenia were established as scores below the 5th or 10th percentile of the appropriate population mean for age and sex. In this case, 10 (100%) of the patients obtained values above the 10th percentile when comparing the data with the Spanish population considering all age ranges. Conclusions: Most of the patients with MCS studied, despite taking avoidance measures including dietary ones, were not malnourished, although they were at risk of developing it. Among the different methods of nutritional assessment, the MNA-SF seems to be the most suitable as a screening method. Sarcopenia does not seem to impact patients with MCS.
