Illness perceptions, coping, and health-related quality of life among individuals experiencing chronic Lyme disease

Current and emerging approaches for eliminating Borrelia burgdorferi and alleviating persistent Lyme disease symptoms

Lyme disease is the most prevalent tick-borne infection caused by Borrelia burgdorferi bacteria in North America. Other Borrelia species are predominately the cause of this disease in Eurasia with some distinct and various overlapping manifestations. Consequently, caution must be exercised when comparing the disease and its manifestations and treatment regimens in North America and Europe. Diagnosis of the early Lyme disease remains difficult using the currently FDA approved serological tests in the absence of a reported tick bite or of erythema migrans in many individuals, non-specific initial symptoms, and the absence of detectable anti-Borrelia antibodies in the prepatent period of infection. Furthermore, it is difficult to distinguish persistence of infection and disease versus reinfection in the endemic regions of Lyme disease by serological assays. If early infection remains untreated, spirochetes can disseminate and could affect various organs in the body with a variety of disease manifestations including arthralgias and musculoskeletal pain, neurologic symptoms and anomalies, and acrodermatitis chronicum atrophicans (ACA) in Europe. Although most patients recover after antibiotic treatment, an estimated ∼10-20% patients in the United States show persistence of symptoms known as post-treatment Lyme disease syndrome (PTLDS). The causes and biomarkers of PTLDS are not well-defined; however, several contributing factors with inconsistent degree of supporting evidence have been suggested. These include antigenic debris, dysregulation of immunological response, bacterial persisters, or combination of these features. This review highlights currently employed treatment approaches describing different antimicrobials used, and vaccine candidates tried to prevent B. burgdorferi infection.

Prevalence and predictors of persistent cognitive and psychological symptoms in non-hospitalized post-COVID-19 patients seeking care at an outpatient post-COVID-19 clinic

Introduction

There is still much uncertainty about why some people develop persistent cognitive and mental health problems after SARS-CoV-2 infection and require additional care while others do not. In this study, we investigated the cognitive and psychological outcomes of non-hospitalized post-COVID-19 patients referred to an outpatient post-COVID-19 clinic for persistent symptoms more than 3 months after infection. Additionally, we aimed to explore the influence of demographic, physical, and personal factors on these outcomes.

Methods

This cross-sectional study was conducted at an outpatient post-COVID-19 clinic located at a prominent clinical teaching hospital in the Netherlands. Participants included non-hospitalized patients referred between 2020 and 2022, more than 3 months after SARS-CoV-2 infection, experiencing persistent symptoms. Main outcome measures included levels of anxiety and depression (Hospital Anxiety and Depression Scale), post-traumatic stress symptoms (PTSS) (Post-traumatic Stress Symptoms Checklist 14), and cognitive symptoms (Checklist for Cognitive and Emotional Consequences). Data analysis employed Spearman correlation and hierarchical multiple regression analyses.

Results

A total of 265 patients (61% female; mean age of 51.7 ± 13.7 years) were included in the study, with an average of 7.6 ± 4.5 months following SARS-CoV-2 infection. Among them, 104 patients (40%) reported high levels of anxiety, 111 patients (43%) showed high levels depressive symptoms, and 71 patients (31%) demonstrated high levels of PTSS. Additionally, 200 patients (79%) reported experiencing more than 2 cognitive symptoms. Bivariate analyses indicated associations between psychiatric history and increased cognitive and psychological symptoms. Multivariate analyses revealed positive associations between physical symptoms and cognitive and psychological symptoms, and catastrophizing thoughts were associated with higher anxiety levels (β = 0.217, p < 0.001). Conversely, positive refocusing was associated with lower depressive symptoms (β = -0.325, p < 0.001), PTSS (β = -0.290, p < 0.001), and cognitive symptoms (β = -0.220, p < 0.001).

Discussion

Among non-hospitalized COVID-19 patients seeking care for persistent symptoms, approximately one-third reported high levels of psychological symptoms, and more than three-quarter experienced cognitive symptoms. Physical symptoms, psychiatric history, and a tendency to catastrophize were identified as potential risk factors for persistent psychological and cognitive symptoms. Conversely, positive refocusing demonstrated a protective effect. These findings contribute to the understanding of long-term COVID-19 outcomes and emphasize the importance of integrating a biopsychosocial perspective into treatment approaches.

Do labels matter? Implications of ongoing symptomatic chronic illnesses labeled as conventional diagnoses vs. functional somatic syndromes

OBJECTIVE

A consideration of chronic illness according to illness labels that are medically understood as opposed to being outside of medical understanding may reveal unique differences in how individuals understand their illness and how such lay understandings relate to health-related quality of life. Study aims are framed according to the commonsense model of self-regulation with a focus on characterizing illness representations according to chronic illness diagnosis type.

METHODS

Individuals suffering from symptomatic chronic illnesses (n  =  192) completed measures of illness representations, coping, and general health. Participants were categorized into one of two groups based on reported diagnosis/symptoms: (a) conventional diagnosis (CD) or (b) functional somatic syndrome (FSS).

RESULTS

FSS participants reported lower illness coherence and greater illness identity than CD participants. Overall, illness coherence predicted negative coping which mediated the relationship between illness coherence and general health.

CONCLUSIONS

Minimal differences were found in illness representations across FSS and CD groups with distinctions found only for illness coherence and identity. Illness coherence stands out as particularly important for coping and health-related quality of life for individuals with ongoing symptoms. Healthcare professionals should work carefully with chronically ill populations to address potential impacts of illness coherence, especially among FSS patients.

Determinants of persistent symptoms after treatment for Lyme borreliosis: a prospective observational cohort study

BACKGROUND

Patients treated for Lyme borreliosis (LB) frequently report persistent symptoms. Little is known about risk factors and etiology.

METHODS

In a prospective observational cohort study with a follow-up of one year, we assessed a range of microbiological, immunological, genetic, clinical, functional, epidemiological, psychosocial and cognitive-behavioral variables as determinants of persistent symptoms after treatment for LB. Between 2015 and 2018 we included 1135 physician-confirmed LB patients at initiation of antibiotic therapy, through clinical LB centers and online self-registration. Two reference cohorts of individuals without LB (n = 4000 and n = 2405) served as a control. Prediction analyses and association studies were used to identify determinants, as collected from online questionnaires (three-monthly) and laboratory tests (twice).

FINDINGS

Main predictors of persistent symptoms were baseline poorer physical and social functioning, higher depression and anxiety scores, more negative illness perceptions, comorbidity, as well as fatigue, cognitive impairment, and pain in 295 patients with persistent symptoms. The primary prediction model correctly indicated persistent symptoms in 71.0% of predictions (AUC 0.79). In patients with symptoms at baseline, cognitive-behavioral responses to symptoms predicted symptom persistence. Of various microbiological, immunological and genetic factors, only lower IL-10 concentrations in ex vivo stimulation experiments were associated with persistent symptoms. Clinical LB characteristics did not contribute to the prediction of persistent symptoms.

INTERPRETATION

Determinants of persistent symptoms after LB were mainly generic, including baseline functioning, symptoms and cognitive-behavioral responses. A potential role of host immune responses remains to be investigated.

Relationships between Anxiety, Depression, and Illness Perceptions in Lung and Breast Cancer Patients throughout the Cancer Continuum

Cancer is a devastating disease that has significant psychological and biological impacts. Generally, lung cancer primarily affects men while breast cancer primarily affects women. Thus, this study aimed to investigate the levels of anxiety and depression in patients with these prevalent cancer types, as well as their perceptions of the illness and any potential connections between them. The study included a total of 252 participants, consisting of 110 breast cancer patients, 112 lung cancer patients, and 30 healthy individuals as controls. The Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) were administered to assess mood, while the Illness Perception Questionnaire (IPQ) was used to evaluate cancer perceptions. Results revealed that both breast cancer and lung cancer patients had significantly higher BDI and BAI scores compared to the control group. Furthermore, the BDI and BAI scores were lower in breast cancer patients compared to lung cancer patients. The IPQ causal representation-immunity score was significantly higher in lung cancer patients than in breast cancer patients (p = 0.01). Positive correlations were found between BDI scores and BAI scores, as well as between BDI scores and certain subscale scores of the IPQ related to illness representation and causal representation. Additionally, a positive correlation was observed between BAI scores and the IPQ illness representation-timeline acute/chronic subscale, while a negative correlation was found between BAI scores and the IPQ causal representation-accident or chance scores. Overall, the study findings demonstrated that breast and lung cancer patients possess negative perceptions of their disease and experience high levels of anxiety and depression. To enhance the quality of life and promote resilience in these patients, it is recommended to incorporate psychological interventions that consider anxiety, depression, and disease perception.

Posttreatment Lyme disease syndrome and myalgic encephalomyelitis/chronic fatigue syndrome: A systematic review and comparison of pathogenesis

Lyme disease is the most common vector-borne illness in the United States and has been causing significant morbidity since its discovery in 1977. It is well-documented that about 10% of patients properly treated with antibiotics never fully recover, but instead go on to develop a chronic illness dubbed, posttreatment Lyme disease syndrome (PTLDS) characterized by severe fatigue, cognitive slowing, chronic pain, and sleep difficulties. This review includes 18 studies that detail the symptoms of patients with PTLDS and uses qualitative analysis to compare them to myalgic encephalitis/chronic fatigue syndrome (ME/CFS), a strikingly similar syndrome. In the majority of the PTLDS studies, at least four of the six major symptoms of ME/CFS were also noted, including substantial impairment in activity level and fatigue for more than 6 months, post-exertional malaise, and unrefreshing sleep. In one of the included PTLDS articles, 26 of the 29 ME/CFS symptoms were noted. This study adds to the expanding literature on the post-active phase of infection syndromes, which suggests that chronic illnesses such as PTLDS and ME/CFS have similar pathogenesis despite different infectious origins.

Quality of life in the older adults: The protective role of self-efficacy in adequate coping in patients with chronic diseases

The purpose of the present study was to establish the association between self-efficacy, perception of disease, emotional regulation, and fatigue and the health-related quality of life in older adults living in the departments of Cesar and Atlántico in Colombia and who have been diagnosed with a chronic disease. The participants were 325 older adults of both sexes, with literacy and no presence of cognitive impairment in the Mini-Mental State Examination (MMSE); A non-probabilistic sampling was carried out. We used the MOS-SF-36 questionnaire, the Brief Illness Perception Questionnaire scale for measuring the perception of disease, the Stanford Patient Education Research Center’s Chronic Disease Self self-efficacy questionnaire for chronic patients, the Difficulties in Emotional Regulation Scale, and the Fatigue Severity Questionnaire as measurement instruments. The design was non-experimental cross-sectional with a correlational scope. The results indicate that self-efficacy, disease perception, emotional regulation and severity of fatigue are variables that could impact the physical function of quality of life, confirming that self-efficacy would work as a factor that decreases the probability that a participant score low on this dimension of quality of life. On the other hand, both the perception of the disease and the severity of fatigue were identified as factors that probably negatively influence quality of life.

Assessment of quality of life in patients with Lyme arthritis and rheumatoid arthritis

Objectives

Patients' quality of life is one of the key concepts of modern medicine, which characterizes the role of physical and mental functioning in the course of the disease. This article presents a stratification of factors influencing the quality of life in patients with rheumatoid arthritis (RA) and Lyme arthritis (LA).

Material and methods

Ninety patients with RA were included in this study among them n = 44 (48.89%) also with LA diagnosis and n = 46 (51.11%) with RA. All studied patients were examined and questioned according to the Health Assessment Questionnaire-Disability Index and the 36-Item Short Form Survey (SF-36) to assess their quality of life. The disease activity score with examination of 28 joints was used to assess the activity of the disease. Multiple regression analysis was used to determine the most significant factors influencing patients' quality of life.

Results

Patients who agreed to participate in the study had high and moderate disease activity; however, patients with LA showed significantly higher baseline data on the intensity of the inflammatory process. According to the analysis of the questionnaire responses, a significantly reduced physical activity of both groups was revealed, but patients with LA had significantly worse BP (p = 0.002), GH (p = 0.006), and Mental Component Summary scales (p = 0.001). The greatest relationship between disease activity and quality of life by Physical Component Summary according to SF-36 (r = -0.80) was found in patients with LA and (r = -0.72) - with RA.

Conclusions

The presence of Borrelia burgdorferi in patients with arthritis not only significantly reduced the motor activity of patients, but also complicated the mental adaptation to their own disease. Factors that affect the quality of life - the activity and duration of the disease in patients of both cohorts, and age and total number of affected joints - for patients with RA.

Coping strategies and quality of life in patients with chronic symptoms visiting a Lyme Center in a Dutch teaching hospital

INTRODUCTION

Little is known on coping strategies in patients with chronic symptoms suspected of Lyme borreliosis (LB). Different coping strategies might influence quality of life (QoL). We assessed coping strategies and QoL in patients with chronic symptoms suspected of LB.

METHODS

Adult patients referred to the Lyme Center Apeldoorn were included (November 2019-April 2021). Participants completed the RAND-36 to assess QoL and the Utrecht Coping List to assess coping strategies. Patient data were extracted from medical records. Patients were categorized based on clinical LB and serology. Linear regression analyses were conducted to examine an association between coping strategies and QoL subscales.

RESULTS

Included were 201 patients. Patients suspected of LB had a different coping profile and lower QoL compared to the reference population. Patients with negative serology and no clinical LB scored lowest on all QoL subscales. In multivariate analyses, correcting for age, gender, comorbidity, and patient category, a negative association was found between passive coping and the QoL subscales physical functioning (β(SE) = - 1.1(0.5)), social functioning (β(SE) = - 3.3(0.5)), role limitations (emotional) (β(SE) = - 5.5(0.8)), mental health (β(SE) = - 3.7(0.3)), vitality (β(SE) = - 2.3(0.3)), pain (β(SE) = - 2.3(0.5)), and general health (β(SE) = - 2.7(0.3)). A negative association was also found between palliative coping and the QoL subscale role limitations (physical) (β(SE) = - 1.8(0.6)) and between expressing emotions and mental health (β(SE) = - 1.3(0.6)). A positive association was found between active coping and the QoL subscales mental health (β(SE) = 1.0(0.3)) and role limitations (emotional) (β(SE) = 1.9(0.8)).

CONCLUSION

In patients suspected of LB, dysfunctional coping strategies were associated with worse quality of life. There is a need for interventions that can guide patients with chronic symptoms suspected of LB towards more active coping and increase QoL.

Post-Treatment Lyme Disease Syndrome: Need for Diagnosis and Treatment

With the continued surge in Lyme disease cases, post-treatment Lyme disease syndrome (PTLDS) is becoming a more pressing health concern. The aim of this review is to identify comprehensive treatment strategies for PTLDS patients. Unfortunately, universal guidelines for diagnosing and treating PTLDS do not currently exist. Consequently, physicians cannot adequately address concerns of possible PTLDS patients. Patients are left suffering and searching for answers, and their activities of daily living and quality of life are adversely impacted. This review highlights that PTLDS clinical trials have focused mainly on treatment with antibiotics, yielding challenging results that lack consistency in inclusion criteria across trials. It will remain exceedingly difficult to extrapolate the outcomes of such studies if a standard for PTLDS diagnosis is not well-established. By focusing on treatment trials rather than establishing diagnostic criteria, research in this field ignores a critical step in investigating PTLDS. The first significant step is to create comprehensive guidelines for the diagnosis of PTLDS, which can generate uniformity and validate PTLDS treatment trials.
