Introduction: The widespread lockdown due to the COVID-19 pandemic was insured by Moroccan authorities in early 2020 to preserve the health of citizens. The lockdown and the pandemic imposed psychological effects on the population including anxiety. Celiac disease (CeD), a chronic disease among the most common inflammatory intestinal disorders, has been linked to adult emotional disturbances. Hence, CeD patients may suffer from anxiety or increase this condition due to the concomitant situation. The objective of this study was to assess COVID-19-related anxiety in a sample of adults with CeD in comparison with a matched healthy group. Method: CeD patients (103) and matched healthy group (101) were investigated using a web-based COVID-19 and related lockdown anxiety survey. Anxiety was assessed with the State and Trait Anxiety Inventory (STAI test: Y1 for state anxiety and Y2 for trait anxiety). Results: State anxiety was present among 65.3% of CeD and 41.6% of the comparison group, and the difference was statistically significant. CeD women suffered more from state anxiety than their compeers in the comparison group (t = 3.23; p = 0.002), and a significant correlation between good compliance to GFD and less state anxiety was found among CeD patients (r = 0.31; p = 0.002). 61.8% of CeD participants thought they were at higher risk of contamination by COVID-19, and they were mostly women (χ2 = 7.66, p < 0.006) and had significantly higher state anxiety mean scores than their compatriots who did not express these thoughts (t = 2.93; p = 0.004). Additionally, 41.5% of CeD participants had anxiety as a trait against 26.7% in the comparison group and the difference between the two groups was statistically significant. Conclusion: Results of this survey allow a better understanding of the health-related pandemic effects on Moroccan CeD patients. It demonstrates that COVID-19 and related lockdowns had a serious impact on the psychological balance of these patients by increasing their anxiety. The survey results underlined the need to improve the psychological care of CeD patients notably by considering remote medical visits during this ongoing pandemic to provide mental health support.

Exposure to certain acute stressors results in an immediate behavioral and physiological response to these situations during a significant period of days. The goal of the current study is to evaluate the long-lasting effect of single exposure of restraint stress among mice after 0 h, 24 h, 48 h and 72 h. Five groups of mice are under experiment: a control group and four groups exposed to one session of restraint stress. All these groups have been studied for behavioral tests in order to evaluate their memories. This is done through a Y-labyrinth and an object recognition test, and anxiety by using open field device. In the second part of the study, enzymatic assays (concerning catalase, glutathione s transferase, glutathione peroxidase and superoxide dismutase) are used to evaluate oxidative stress. The enzymatic activity of the antioxidant system is assessed in five brain structures, including the cerebellum, olfactory bulb, spinal bulb, hypothalamus, and hippocampus. The obtained results show that acute restraint stress leads to a decrease in memory function and to the development of an anxious state; concomitant to an increase of locomotor activity afterword. It causes disturbance of antioxidant balance in the brain by developing a state of oxidative stress. Indeed, restraint stress causes a change in anti-oxidant stress enzymatic activity in the brain, notably in post-stress period. In conclusion, acute restraint stress is responsible for altering cognitive functions, especially memory, and the development of anxious behavior, which could be a result of the generation of oxidative stress; effects that are persistent over an important period after the cessation of stress.
