This study investigated the impact of the COVID-19 pandemic on the health- related quality of life of 224 IBD patients. Among them, 197 were diagnosed with Crohn's disease (CD), 14 with ulcerative colitis (UC), and 13 were undiagnosed. Notably, CD patients represented the majority of our survey participants. Previous research has examined the influence of COVID-19 on the health of patients with chronic diseases, including IBD. The relationship between chronic illnesses and psychological disorders is multifaceted. On one hand, psychological stress can exacerbate organic diseases through neuroendocrine and inflammatory mechanisms. On the other hand, chronic illnesses can act as a source of stress, leading to subjective stress and excessive health problems due to sustained overload [20]. IBD patients are particularly susceptible to psychological symptoms such as anxiety, fear, and depression when compared to the general population [21, 22]. Consequently, the COVID-19 pandemic appears to have had a significant impact on IBD patients [23]. In our survey, only 97 (43.3%) IBD patients reported never feeling discouraged, while the remaining 127 (56.7%) experienced varying degrees of negative psychological responses. Similarly, only 21 (9.38%) IBD patients reported never feeling nervous, while the majority of 203 (90.62%) IBD patients frequently experienced tension. Therefore, intervening in the emotional well-being of IBD patients is crucial to enhancing their HRQoL during the COVID-19 pandemic.
In our study, the majority of IBD patients (129) were being treated with mesalazine (5-ASA). There are reports in the literature suggesting that medications used to treat IBD can influence the immune system, modulate immunity, and potentially increase the susceptibility of IBD patients to COVID-19 infection [24]. Specifically, IBD patients using steroids and 5-ASA are considered to be at a higher risk of contracting COVID-19 [25]. Conversely, biological agents (anti-TNF-α) are considered a protective factor against severe COVID-19, possibly due to the overexpression of TNF-α in COVID-19 [24]. Among the 224 IBD patients in our survey, 172 were found to have contracted COVID-19, representing 77% of the participants. Some studies indicate that IBD patients are indeed more vulnerable to COVID-19 [20]. Several factors contribute to this susceptibility. Firstly, medications used to treat IBD, such as steroids and 5-ASA, may heighten the risk of COVID-19 infection among IBD patients [25]. On the other hand, some biological agents may offer protection [24]. However, the mechanisms of these medications are not yet fully understood, necessitating further research to comprehensively assess the risk of COVID-19 infection in IBD patients and the efficacy and risks associated with immunomodulators. This research will guide clinicians in making informed decisions regarding drug selection. Additionally, studies have demonstrated variations in the rate of COVID-19 infection among IBD patients both in China and abroad. In China, the incidence of IBD is significantly lower than in Europe and the United States. Furthermore, the Chinese IBD Society released guidelines for managing IBD in early 2020, offering recommendations from gastroenterologists on home isolation, dietary choices, personal protection, and the use of immunosuppressants, biological agents, and cytokine blockers to prevent COVID-19 [21].
Our findings also reveal that COVID-19 infection is unrelated to gender, age, IBD type, surgical history, comorbidities, COVID-19 vaccination, or the use of biological agents. Furthermore, we observed that patients with UC generally exhibit a better HRQoL when compared to CD patients. Optimism throughout the pandemic is associated with a higher HRQoL among IBD patients. Consistently following medical recommendations and adhering to IBD treatment regimens is also correlated with improved HRQoL in comparison to patients who inconsistently use IBD treatment drugs.
Our study underscores the observation that UC patients generally report a higher HRQoL than CD patients. This discrepancy may be attributed to several factors. Firstly, CD and UC have different pathogenic mechanisms. CD can affect various segments of the gastrointestinal tract, has the potential for transmural involvement, and can lead to complications such as intestinal perforation and fistulas. In contrast, UC primarily affects the mucosal layer of the rectum and colon and is typically associated with fewer systemic symptoms when compared to CD [26]. Moreover, delayed diagnosis of IBD, particularly in CD, is common and associated with adverse outcomes, contributing to the lower HRQoL among CD patients [27]. It is worth noting that previous literature reports have yielded inconsistent findings regarding the relationship between IBD type and HRQoL. While some studies suggest no significant differences in HRQoL based on IBD type [21, 23, 28], others report worse HRQoL in UC patients [25]. Nevertheless, certain studies align with our findings, indicating improved HRQoL in UC patients [29]. We speculate that the discrepancies in reported outcomes across different literatures may be attributed to variations in sample sizes and differences in statistical methods employed in various studies. Our research further illustrates that IBD patients who maintain a positive outlook during the COVID-19 pandemic exhibit higher HRQoL compared to those who experience depression. Relevant literature indicates that the COVID-19 pandemic has had a substantial impact on the physical and mental well-being of individuals [30, 31]. During the pandemic, the general public in many countries reported elevated levels of depression, anxiety, psychological distress, and post-traumatic stress disorder [31–33]. Furthermore, the prevalence of anxiety and depression among IBD patients is at least twice as high as that of the general population. Previous reports indicate that during the COVID-19 pandemic, IBD patients experiencing depression and anxiety are more likely to report reduced sleep quality and a diminished quality of life compared to those who maintain an optimistic outlook [34]. This aligns with our study's findings.
Our research results underscore that IBD patients who adhere to medical advice and consistently take prescribed medications for their condition report a higher HRQoL compared to patients who do not consistently follow their treatment regimen. Earlier literature has also yielded consistent findings, suggesting that the decrease in HRQoL is linked to discontinuation of medication during the COVID-19 pandemic [21]. Additionally, studies have shown that the COVID-19 pandemic has had multifaceted effects on IBD patients [24]. Due to the pandemic, many IBD patients may encounter challenges in seeking medical care or resort to online consultations, making it difficult to obtain prescription medications, such as biologics and immunosuppressants. The pandemic may also lead to shortages of these medications [20, 21, 24]. Consequently, some IBD patients may struggle to adhere to their prescribed medication regimens, particularly for IBD patients who during periods of remission and relapse, if they discontinue taking medicine in such cases could exacerbate their condition and reduce their HRQoL [21, 24]. Our recommendation is that all IBD patients should continue taking their prescribed medications for IBD as directed by their healthcare providers during the COVID-19 pandemic and strive to avoid discontinuing their IBD medications. Medication management is a critical measure for controlling IBD symptoms and maintaining remission [28].
This study provides valuable insights into the impact of the COVID-19 pandemic on the HRQoL of IBD patients, particularly during the post-zero-COVID policy era in China. The findings underscore the need for continued support and psychological care for IBD patients in challenging circumstances. However, it is important to note that while this study offers significant insights, there are limitations that should be considered. First, the data were collected through web-based questionnaires, which may introduce selection bias, as participants may not be representative of all IBD patients, and, there is an imbalance in the proportion of CD and UC patients within our study sample, with a higher percentage of CD patients. Therefore, this is one of the potential reasons causing a potential bias in our study results Additionally, self-reporting in questionnaires may lead to recall bias and inaccuracies in responses. Moreover, the cross-sectional design of this study does not allow for the establishment of causal relationships between variables. Longitudinal studies could provide a more comprehensive understanding of the dynamic changes in HRQoL among IBD patients during the pandemic. Furthermore, the survey was conducted in a specific region of China, and the results may not be fully generalizable to other regions or countries with different healthcare systems and policies.
Despite these limitations, this study contributes to the limited body of literature on the impact of the COVID-19 pandemic on HRQoL of IBD patients, especially in the context of policy changes in China. The findings suggest that healthcare providers should pay attention to the psychological well-being of IBD patients during pandemic situations and provide appropriate support and interventions to help them maintain a positive attitude and adhere to treatment regimens.
Due to the limited availability of relevant literature, this study is exceptionally valuable, innovative, and irreplaceable, offering valuable insights into the HRQoL of IBD patients during COVID-19 outbreaks worldwide. Future research in this area could explore the effectiveness of psychological interventions, such as counseling and support groups, in improving the HRQoL of IBD patients during times of crisis. Additionally, investigating the impact of different COVID-19 variants on the experiences of IBD patients and outcomes could provide valuable insights into the evolving nature of the pandemic.
