BACKGROUND: Prolonged social isolation as a result of the COVID-19 global pandemic has been a source of considerable psychological distress for many people. This can manifest in many ways and if left undetected can impact negatively on general health. It is essential to understand the impact of these conditions on inflammatory arthritis (IA) patients, especially axial spondyloarthropathy (axSpA). AIM: To capture the level of psychological distress for patients with IA following prolonged social isolation. METHODS: A survey was sent out to patients with a confirmed diagnosis of IA. This captured changes in sleep, mood, disease activity, employment and general health since the beginning of the social isolation period. A PHQ-4 (Patient Health Questionnaire) was included to determine level of psychological distress. RESULTS: Females with IA reported significantly higher rates of decline in general health (40% vs 16%, p = 0.01), mood disturbance (43.4% vs 26%, p = 0.03) and increased disease activity (50% vs 16%, p = 0.01) compared to males. Evaluating the mean PHQ-4 scores, no significant difference was noted between genders (4.80 vs 3.44, p = 0.10). However, females demonstrated a non-significant trend toward increased rates of moderate to severe psychological distress (40% vs 30%, p = 0.13). Subanalysis of patients with axSpA found high rates of moderate to severe distress in both genders. CONCLUSIONS: Females with IA reported significantly higher rates of decline in general health, mood disturbance and increased disease activity during the period of social isolation. This was reflected in a trend towards greater levels of psychological distress.

Quarantine and social isolation are public health measures used to contain and prevent the spread of an infectious disease [1] . Throughout human history, a number of infectious diseases have required periods of quarantine to prevent widespread illness and death. Use of these measures were first described in Venice due to the Black Plague, with more recent mandated quarantines for the SARS and Ebola outbreaks [2] . The COVID-19 pandemic is unprecedented in many ways, with almost 4 billion of the world's population required to live in social isolation. In Ireland, and much of the EU, the social isolation has now gone on for over 3 months. Although restrictions are slowly being lifted, it is expected that social distancing and normal life as we know it will not be able to resume until a vaccine is widely available.

This prolonged period of social isolation has affected multiple aspects of everyday living. These disruptions have the potential for far reaching effects if not identified and addressed promptly. During this time, a number of households are under significant financial strain, without childcare, working from home and managing remote education for children. These new challenges in addition to concerns around COVID-19 infection and transmission could lead to significant psychological distress.

Given the setting of a global pandemic, some distress is to be anticipated. However, cases of extreme psychological distress, if left unrecognized, can impact both general health in addition to significantly affecting long-term mental health. It is essential to identify patients at high risk of developing severe psychological distress and address the triggers when possible.

Inflammatory arthritis (IA) refers to systemic autoimmunemediated diseases affecting the joints. Patients with this type of diagnosis commonly require lifelong medication to decrease inflammation, manage symptoms and prevent progression of disease. Regular exercise and stretching is also an e s s e n t i a l c o m p o n e n t o f m a n a g e m e n t . A x i a l spondyloarthropathy (axSpA) is a form of IA affecting the sacroiliac joints and the spine [3] . Patients with axSpA have been previously shown to have increased rates of depression [4] and there is a trend towards higher levels of disease activity in patients with depression [5] . For this reason, it is essential to understand the impact of the COVID-19 pandemic on axSpA patients, in order to address their needs and concerns in the months to come. The aims of this study are to capture the level of psychological distress for patients with inflammatory arthritis and understand how this is affecting their disease and general health.

A survey was distributed in May 2020, to patients attending the department of Rheumatology in St James' Hospital. Eligible patients were over the age of 18, fluent in English and had a confirmed diagnosis of inflammatory arthritis The survey captured information on changes in sleep, mood, disease activity, exercise, employment and general health since the beginning of the social isolation period. Changes were quantified as improved, no change or worsened.

A PHQ-4 (Patient Health Questionnaire) was included to determine level of psychological distress. This four-question tool generates a numerical result corresponding with the following levels of psychological distress: 0-2 = none, 3-5 = mild, 6-8 = moderate, 9-12 = severe. To capture level of social interaction, patients were asked if they were in isolation with other people or alone. For patients who were employed, they were asked if they were working remotely or on site.

Analysis was performed using IBM SPSS version 26. An independent sample t test was used to test for significance in differences of means between groups, including age and PHQ-4 scores. A Chi 2 test for independence was used to test categorical variables. A p value of < 0.05 was deemed significant. PHQ-4 scores were tested by mean overall scores and prevalence of each category between comparison groups.

In total, 88 completed surveys were returned, of these 80 contained data on gender and were included in this analysis. Patients were 37.5% (30) females and 62.5% (50) males with a mean age of 50.7 years (Table 1) . Population was predominantly axSpA patients, 73.8% (59) with 26.3% (21) patients with inflammatory arthritis. Fifty percent (40) were currently employed; of this, 47.5% (19) of patients were working from home. Of the 54.5% (48) of patients who were unemployed, 35% (17) had become unemployed since the covid-19imposed shutdowns began. Mean PHQ-4 score was 4.10, corresponding with a level of mild psychological distress. Analysis of patients by diagnosis revealed no significant differences in outcome measures between IA and axSpA. Patients with IA were noted to be older that axSpA patients (57.9 vs 48.3, p = 0.02).

Eighty responses contained data on gender. Overall, females reported significantly higher rates of mood disturbance (43.4% vs 26%, p = 0.03) and increased disease activity (50% vs 16%, p = 0.01) compared to males (Table 1) . Females also reported high rates of decline in general health (40% vs 16%, p = 0.01). No differences were detected in sleep quality or weekly exercise. Similar rates of employment were noted in both groups.

No significant difference was detected in mean PHQ-4 scores or distribution or level of psychological distress; however, females demonstrated a non-significant trend towards higher rates of severe distress (20% vs 8%, p = 0.13) (Fig. 1) .

Further analysis focused on axSpA patients alone on the basis of gender. Of the 59 axSpA patients included in the analysis, 30.5% (18) were female and 69.5% (41) male ( Table 2) . AxSpA females had higher rates of decline in general health (50% vs 17.1%, p = 0.02) and increased disease activity (50% vs 17%, p = 0.04) compared to axSpA males. Although axSpA females had increased rates of mood disturbance (44.4% vs 26.8%, p = 0.1), this did not reach significance.

No significant difference was noted in mean PHQ-4 scores (4.78 vs 3.44, p = 0.18) or level of psychological distress, but axSpA females demonstrated a non-significant trend towards higher rates of psychological distress than males (Fig. 2 ).

The COVID-19 global pandemic led to an abrupt and prolonged period of social isolation to stem spread of the virus. This analysis demonstrates the significant effect of these lifestyle changes on patients with inflammatory arthritis. Use of the PHQ-4 allowed for quantification of the level of psychological distress during this time with over 59% of patients surveyed reporting some level of distress. Females reported high levels of decline in general health, mood disturbance and increased disease activity. This is reflected in higher mean PHQ-4 scores and increased rates moderate to severe psychological distress in females compared to males. Subgroup analysis of the axSpA patients alone reached demonstrated similar findings but did not reach significance in variation of mood disturbance.

Previous studies have shown that prolonged social isolation can lead to decreased work performance and increased risk of mental health disorders [6] . Addressing the issues identified in this analysis will require considerable time, education and energy from clinicians. Recognising those most affected is only the first step in aiding recovery. The WHO has encouraged healthcare workers to be familiar with resources available to support patients requiring psychosocial support [7] . Encouraging regular exercise [8] , increased reliance on digital communication [9] and social integration [10] are strategies proposed to decreased psychological distress under current restrictions.

It is unclear why disease activity and general health outcomes are worse in females than males. One potential contributing factor is the increased rates of females working from home, while males more commonly worked on site. Females also reported higher rates of sleep disturbance which did not reach significance but could be contributory. Discussion with individual patients to identify potential causes of distress would provide further insight into this issue.

As this study was conducted via mail survey with an overall response rate of 44%, a potential limitation of the study was nonresponse bias. However, the sample respondent groups were highly representative of both patient populations surveyed in terms of age and gender, which has been shown to decrease the risk of nonresponse bias [11, 12] .

This analysis demonstrates that the impact of the pandemic extends beyond physical well-being and disease activity. Prompt recognition of psychological distress and other effects of prolonged social isolation will help in managing patients going forward.
