Profiling the microbiome of oral and genital mucosal surfaces in Behçet's disease.

Almost 90% of Behçet's patients present with oral and/or genital ulcers which influence the disease outcome. We hypothesised that the dysregulation of the oral and genital microbiome, coupled with dysregulation of the immune response, contributes to the aetiopathogenesis of Behçet's Disease (BD) and drives disease activation. METHOD: 152 BD patient samples; 70 matched oral and genital samples plus 12 unmatched samples (Female: Male, 58:12; mean age, 42 ± 13.9: 39.3 ± 10.3) to profile microbial community high-throughput sequencing of the microbiome using 16 s rRNA sequencing targeting the V1/V2 and V3/V4 hyper variable regions were used and results reviewed in relation to disease severity, Work and Social Adjustment Scale (WSAS) outcomes and medication. RESULTS: Alpha and beta diversity were significantly decreased in genital compared to oral samples; p value<0.05. However, grouping the samples as to whether ulceration was present was not significant. Escherichia-Shigella was the only Amplicon Sequence Variants (ASVs) in the V1/V2 region that was shared between the oral mucosa with ulcer (O_U) and genital mucosa with ulcer (G_U) groups. This was in contrast to the V3/V4 region which indicated that Lachnospiraceae, Saccharimonadales, and Coriobacteriales were shared between the O_U and G_U groups. In addition, gender had no impact on the bacterial abundance in V1/V2 analysis of the oral and genital samples. V3/V4 analysis of genital samples demonstrated that Lactobacilli and Gardnerella were significantly increased in females (20 times) compared to the males in samples; p-adj <0.05. Interestingly in BD patients, Rothia which is commonly found in the mouth was present in both oral and genital samples. Streptococci were significantly increased while Veillonella significantly decreased in the presence of oral ulceration in the BD cohort. The clinical phenotype had no effect on V1/V2 and V3/V4 on the bacterial abundance of oral samples. However, medication e.g. colchicine had a significant effect on the oral microbial abundance (V1/V2; P = 0.020, V3/V4; P = 0.003). There was no relationship between colchicine and the presence/absence of genital ulcers. BD patients with active disease had higher WSAS scores, and their bacterial abundance differed significantly from the non-active BD patients (ADONIS, R2 = 0.05, p value =0.029). CONCLUSION: The presence of the microbes Streptococcus, Veillonella, Gardnerella, Lactobacillus, Atopobium, Peptoniphilus, Corynebacterium and Staphylococcus may provide early evidence of BD patients are with active disease.

The impact of the COVID-19 pandemic on patients with Behçet's syndrome within the framework of Maslow's hierarchy of needs: implications for patient empowerment in national or global emergencies.

OBJECTIVES: The aim of this online survey was to assess the impact of the COVID-19 pandemic on patients with Behçet's syndrome (BS) using Maslow's hierarchy of needs. METHODS: Sixty-eight BS patients from the UK completed an online questionnaire that covered three components of Maslow's hierarchy of needs regarding Physiological needs (sleep, food, mobility), Safety needs (employment, health), Social needs (relationships), personal precautions and main concerns regarding COVID-19. RESULTS: The patients received a letter from the NHS (66.2%) advising shielding. Health concerns were addressed using Tele-medicine by telephone consultations and e-mails to access BS specialists during lockdown (44.1%; 27.9%). In addition, patients also obtained information through official government and Behçet corporate health web pages related to Behçet's disease for self-empowerment. During lockdown, their weekly working hours were reduced (26.65±13.86 vs. 20.79±17.94) (p=0.017) and the employment rate was decreased (32.6% vs. 26.7%) in comparison to pre-lockdown. Moreover, the reduction in frequency of exercise per week (4.39±1.94 vs. 3.71±2.26) and healthy food consumption (73.5 % vs. 47.1%) per week were also reported (p=0.007; p=0.001, respectively). Furthermore, patients experienced sleeping less (54.4%) and feeling lonely (66.1%). CONCLUSIONS: Using Maslow's hierarchy of needs provided a framework for reviewing the quality of basic needs in patients' life during lockdown. These needs are required for healthy social lives and the deprivation should be considered while considering healthcare planning. Since lockdown appeared to have a negative influence on patients' lives and disease management in the framework of patient-centred, the empowerment of patients gained importance at this point.

The impact of multifactorial factors on the Quality of Life of Behçet's patients over 10 years.

Objective: This study analyses the 2020 survey and reviews the 2009, 2014 surveys to ascertain which Behçet's symptoms, personal and family status, patients' lifestyle, and work-related outcomes impacted on Health-Related Quality of Life (HRQoL). Methods: Four hundred and fifty-nine Behçet's patients submitted an online survey/questionnaire. Patients provided information on socio-demographic characteristics, disease duration, historical and current symptoms, systemic and topical medication, health related lifestyle, work-related outcomes regarding employment status and claiming benefits and Quality of Life (QoL) measured by EQ-5D index. Results: Four hundred and nineteen patients met the inclusion criteria, and 371 who had full data (Males: Females: Others = 84:285:2, mean-age = 41.1 ± 23.3:38 ± 13.2:40 ± 5). The main symptoms associated with patients seeking medical care were mouth ulcers 30% and genital ulcers 23%, joint 14%, and eye problems 9%. The EQ-5D index for 2009, 2014, 2020 was (mean ± SD); 0.47 ± 0.38, 0.42 ± 0.37, 0.34 ± 0.40, respectively, p < 0.05. 2020 patients had the worst values of the five domains compared to 2014 and 2009. Interestingly, mobility value was the same over the 10 years of monitoring patients. Behçet's syndrome (BS) symptoms that had significant negative impact on QoL were; 2009 (arthropathy, neurological problems, pathergy reaction, and stomach/bowel symptoms), 2014 (arthropathy, headache, neurological problems, pathergy reaction, and skin lesions), 2020 (arthropathy, neurological problems, and stomach/bowel symptoms). The 2014 and 2020 surveys reported the QoL is significantly better in patients on immunosuppressant, who did sport, continued in employment and not receiving benefits. Conclusion: Joints and neurological symptoms are the main symptoms which had negative impact on BS patients over the 10 years, sociodemographic (gender, age, marital, and education status), lifestyle (medication, cannabis, drinking wine, and regular exercise), employment status (employee and no career change), and accessing benefits (never claim benefit) had significant influence on patients' HRQoL.

Why are Behçet's disease patients always exhausted?

OBJECTIVES: Patients with Behçet's disease (BD) constantly complain of fatigue and many have problems with poor sleep. This ultimately has a major impact on all aspects of normal living. To attempt to understand this, Artificial Intelligence (AI) was used to identify potential biomarkers. These were alpha-melanocyte stimulating hormone (α-MSH), vasoactive intestinal peptide (VIP) and some inflammatory cytokines. We assessed the association of fatigue, quality of sleep and disease activity with circulating concentration of α-MSH, VIP and inflammatory cytokines. METHODS: There were 127 participants, 97 BD patients, and 30 healthy controls (HC). All completed the Multi-Dimensional Assessment of Fatigue questionnaire (MAF) and the Pittsburgh Sleep Quality Index (PSQI) on the day of their clinical assessment. Enzyme-linked immunosorbent assays (ELISA) were used to evaluate the serum concentrations of α-MSH, VIP and cytokines (IL-1ß, IL-6, IL-10, and TNF-α). RESULTS: 64% of BD patients experienced high fatigue scores, and 63% had poor quality of sleep. When BD and HC were compared the MAF and PSQI scores as well as the serum concentrations of α-MSH, VIP, and IL-6 were significantly higher in BD (p values were: 0.001, 0.001, 0.001, 0.004 and 0.036, respectively). Both α-MSH and IL-6 had significant impact on MAF and PSQI. Interestingly, VIP had a significant influence on PSQI and disease activity, but not on MAF. CONCLUSIONS: A better understanding of these complex clinical and biochemical interactions between α-MSH, VIP and IL-6 might lead to the development of novel approaches to manage fatigue and sleep disorders as well as disease activity in BD patients.

Behçet's syndrome and health-related quality of life: influence of symptoms, lifestyle and employment status.

OBJECTIVES: Behçet's syndrome (BS) is a chronic multisystemic disorder. The complex pattern of BS symptoms can effect negatively on patients' quality of life. The aim of this study is to evaluate the influence of BS symptoms, oral health related lifestyles and employment status on Health Related Quality of Life (HRQoL). METHODS: A questionnaire was mailed to a cohort of 641 adult members of the Behçet's Syndrome Society (BSS) and patients attending a Behçet's syndrome centre in the UK. Respondents gave information on socio-demographic characteristics, disease duration, current symptoms, symptom control, health related lifestyle, diet, smoking and alcohol, employment status and quality of life (the EQ-5D index). RESULTS: 315 out of 426 BS participants (Males: Females=136:179) were recruited. BS symptoms and EQ-5D score model (R=0.67 and R2=0.45) and standardised coefficients for symptoms were; arthropathy (-0.336), headache (-0.227), neurological problems (-0.135), pathergy reaction (-0.119) and skin lesions (-0.107) in decreasing order. This finding was similar to a 2009 study of the same cohort. Regression analysis of tobacco consumption revealed that tobacco use was a risk factor for decreasing the EQ-5D score (beta value = - 0.72, p=0.001). Using an effective mouthwash has a positive impact on HRQoL (beta value= 0.149 and p=0.012). The mean EQ-5D in patients who continued in employment and who were not receiving benefits was better compared to other sub groups. CONCLUSIONS: BS symptoms, employment status, a healthy lifestyle combined with a good oral health have a significant impact on the HRQoL of BS patients.
