Quality of life and depression in patients with amyotrophic lateral sclerosis - does the country of origin matter?

BACKGROUND: Given the inevitable relentless progressing nature of amyotrophic lateral sclerosis (ALS), it is essential to identify factors influencing patients' wellbeing. The study aimed to prospectively assess factors influencing the quality of life (QoL) and depression in ALS patients compared to healthy controls (HCs) from Poland, Germany and Sweden and their relationship to socio-demographic and clinical factors. METHODS: 314 ALS patients (120 from Poland, 140 from Germany, 54 from Sweden) and 311 age-, sex- and education-level-matched HCs underwent standardized interviews for quality of life, depression, functional status and pain. RESULTS: Patients from all three countries showed similar levels of functional impairment (ALSFRS-R). Overall, ALS patients assessed their quality of life as lower compared to HCs (p < 0.001 for the anamnestic comparative self-assessment (ACSA), p = 0.002 for the Schedule for the evaluation of the subjective quality of life - SEIQoL- direct weighting (SEIQoL-DW). Also, the German and Swedish patients, but not the Polish, reported higher depression levels than the corresponding HCs (p < 0.001). Analysis of ALS groups revealed that functional impairment was related to a lower quality of life (ACSA) and higher depression levels among German ALS patients. Longer time since diagnosis predicted lower depression and (in male subjects) higher quality of life. CONCLUSIONS: ALS patients assess their quality of life and mood lower than healthy individuals within the studied countries. The relationships between clinical and demographic factors are moderated by country of provenance, which bears implications for the design and interpretation of scientific and clinical studies, which should reflect the complexity and heterogeneity of mechanisms determining QoL.

Religiosity in patients with amyotrophic lateral sclerosis, a cross-country comparison.

PURPOSE: Amyotrophic lateral sclerosis (ALS) is a progressive motor impairment leading to early death. Religiousness is one of the factors potentially alleviating the psychological burden of patients. However, its role might vary according to cultural context. Our study aimed to analyze religiosity, and its clinical, psychological and socio-demographic correlates in ALS patients and controls, comparing two European countries with different cultural backgrounds. METHODS: 268 Polish and German ALS patients, including 18 with locked-in syndrome (LIS) and 198 healthy controls (HC) were interviewed about religiousness, quality of life (Qol), depression, functional status and pain. A follow-up was conducted on 71 patients. RESULTS: Polish subjects had a significantly higher level of public, private and general religiosity than the German sample. Importantly, we found no difference in total and public religiousness between ALS patients and HC within either population. Only the private religiousness was significantly higher in German patients compared to controls. In the same sample, private religiousness correlated with functional impairment due to disease progression. In ALS groups and LIS patients, religiousness did not correlate with any disease-associated factors: disease duration, pain, Qol or depression. Follow-up comparisons in the ALS group revealed worsening functional status, increased depression and no significant change in religiosity. CONCLUSIONS: Religiosity was linked to the cultural background rather than ALS. Generally, it did not correlate with clinical, psychological and socio-demographic parameters and was stable throughout disease progression. The only exception was the relationship between the functional decline and private religiosity among German patients.

The quality of life and depression in primary caregivers of patients with amyotrophic lateral sclerosis is affected by patient-related and culture-specific conditions.

Objective: To analyze the quality of life (QoL) and frequency of depression in primary caregivers of patients with amyotrophic lateral sclerosis (ALS) in two neighboring European countries. Methods: a cross-sectional study performed in 164 dyads of ALS patients and caregivers followed at clinical ALS centers in Poland and Germany between 2015 and 2018. The quality of life (Anamnestic Comparative Self-Assessment - ACSA, Quality of Life in Life-Threatening Illness - Family Carer Version - QOLLTI-F) and depression (ALS-Depression-Inventory 12-Items - ADI-12) of the caregivers was assessed and correlated with caregivers- and patient-related factors. Patient's clinical status was assessed by ALS Functional Rating Scale - revised and the Behavioral Score of the Edinburgh Cognitive and Behavioral ALS Screen. Results: the caregivers reported a positive QoL associated with functional and behavioral status of the patient, disease duration and caregivers's depression The most impaired domains of the QoL differed depending on the country of provenance, cultural background and/or social support of the caregivers. Depression was present in 1/3 of the caregivers and was significantly more frequent in the Polish group. It positively correlated with female gender, disease duration, sleep disturbances and functional decline. Both QoL and mood were significantly lower in the caregivers more burdened with the functional care of the patients. Conclusions: the wellbeing of caregivers of ALS patients is affected by patient-related and culture-specific conditions. Understanding the needs and background of psychological adaptation of the caregivers from various countries may translate into better QoL and local patient care.

Attitudes of caregivers towards prolonging and shortening life in advanced stages of amyotrophic lateral sclerosis.

INTRODUCTION: Inevitable disease progression in amyotrophic lateral sclerosis (ALS) forces patients and their caregivers (CGs) to reflect on end-of-life treatment. The CGs are often heavily burdened with their role of surrogate decision-makers. The aim of the study was to analyze attitudes of CGs and presumable attitudes of ALS patients from the CGs' perspective towards palliative care in advanced disease stages. MATERIAL AND METHODS: One hundred and sixty four CGs from Germany and Poland were interviewed regarding their own preferences and patients' ideational attitudes towards life-prolonging (invasive and non-invasive ventilation, tube feeding) and life-shortening methods (termination of measures, active measures if permitted by law). The data were correlated with patient- and CG-related factors: demographic and clinical data, care commitment, depression and quality of life (QoL). RESULTS: The CGs were mostly female spouses of ALS patients, with secondary/higher education. Nearly 70% (81% in Poland, 57% in Germany; p = 0.0001) reported positive attitudes towards life-prolonging methods, which positively correlated with religiousness and negatively with patients' age. Approximately 40% of CGs (25% and 51% respectively; p = 0.001) reported positive attitudes towards life-shortening methods. It positively correlated with time since diagnosis and negatively with the CG's QoL, religiosity and religious/spiritual faith as factors that significantly influenced end-of-life decisions. There was a strongly positive correlation between CGs' positive attitudes towards life-shortening methods and presumed positive patients' attitudes assessed by their CGs ( p < 0.000001). CONCLUSIONS: Although attitudes towards treatment differed between countries, the CGs of ALS patients were generally positive towards life-prolonging treatment. A greater acceptance of life-shortening methods in the case of longer disease duration and poorer QoL may indicate worse coping with disease progression and weaker adaptation mechanisms in CGs compared to those previously reported in ALS patients. A close resemblance of the CGs' answers to probable patients' attitudes reported by the CGs indicates that many GCs might actually express their own culturally shaped attitudes towards end-of-life methods. In light of earlier-reported discrepancies between presumed opinions of the CGs and of patients themselves, a greater focus should be placed on thorough discussions on future treatment options with ALS patients in the presence of their CGs, to stay in line with the patient's authentic will.

Caregivers' divergent perspectives on patients' well-being and attitudes towards hastened death in Germany, Poland and Sweden.

Background: During the course of amyotrophic lateral sclerosis (ALS), patients and their families are faced with existential decisions concerning life-prolonging and -shortening measures. Correct anticipation of patient's well-being and preferences is a prerequisite for patient-centered surrogate decision making. Methods: In Germany (N = 84), Poland (N = 77) and Sweden (N = 73) patient-caregiver dyads were interviewed. Standardized questionnaires on well-being (ADI-12 for depressiveness; ACSA for global quality of life) and wish for hastened death (SAHD) were used in ALS patients. Additionally, caregivers were asked to fill out the same questionnaires by anticipating patients' perspective (surrogate perspective). Results: Caregivers significantly underestimated patients' well-being in Germany and Poland. For Swedish caregivers, there were just as many who underestimated and overestimated well-being. The same was true for wish for hastened death in all three countries. For Swedish and Polish patients, caregivers' estimation of well-being was not even associated with patients' responses and the same was true for estimation of wish for hastened death in all three countries. Older caregivers and those with the most frequent encounter with the patient were the closest in their rating of well-being and wish for hastened death to the patients' actual state, while caregivers with chronic disease him/herself were more likely to underestimate patient's well-being. Discussion: Despite distinct cultural differences, there was a clear discrepancy between patients' and caregivers' perspective on patients' well-being and preferences towards life in all three countries. This possible bias in caregivers' judgment needs to be taken into account in surrogate decision making.

Motor neuron disease beginning with frontotemporal dementia: clinical features and progression.

Objective: To study disease characteristics, progression and outcome in a group of motor neuron disease (MND) patients beginning with frontotemporal dementia (FTD) by comparing them with patients with the typical motor-onset. Methods: 849 patients recruited from tertiary centers were studied according to FTD-onset and motor-onset. We studied clinical data, functional decline and survival. Results: Twenty six patients (3.1%) had FTD-onset of whom seven (26.9%) had coincident motor dysfunction. In those with isolated FTD-onset, motor symptoms developed after a median of 12 months (IQR: 4-18). FTD-onset patients were older at presentation; the bulbar-region was more frequently first affected than in the motor-onset group; there was a predominant upper motor neuron (UMN) phenotype; fasciculations were less common than in motor onset disease but facial and upper limb apraxia was more frequent; as well as ALS and FTD familial history. No differences were observed for gender, frequency of C9orf72 hexanucleotide repeat expansion, family history of Alzheimer's and Parkinson's diseases, median delay from motor symptoms to diagnosis, median ALSFRS-R rate of change, handedness, emotional lability, depression, weight loss, resting tremor, bradykinesia, sensory changes or neuropathy. Clinical and demographic features were similar between FTD-onset patients developing bulbar MND and bulbar-onset ALS patients. Once bulbar symptoms manifested functional progression and survival were similar to those of bulbar-onset ALS patients. Conclusions: MND patients with FTD-onset have a distinctive phenotype characterized by predominant UMN presentation and rapid progression to bulbar involvement. The main factor impacting functional decline and survival is the onset of bulbar dysfunction.

ALS and fertility: does ALS affect number of children patients have?

OBJECTIVE: Amyotrophic Lateral Sclerosis is one major disease in the group of neurodegenerative conditions. As with most other neurodegenerative diseases, clinical signs of the disease usually show among the elderly population, and most commonly around 60-65 years of age. Therefore the disease is not expected to impact the fertility of ALS patients. When examined from an evolutionary medicine and evolutionary biology perspective, there should be no selection pressure on the patient population due to the late onset of ALS. Methods: In this study, we tested the hypothesis that ALS does not affect fertility on a group of patients with ALS that we collected in a multi-center study. We recruited 511 patients diagnosed with ALS according to the revised El Escorial criteria, and 236 control cases without a neurodegenerative disease. We compared the ALS group's number of offspring with the control group in three consecutive generations. Results: No statistically significant difference was found between the number of siblings of ALS and control groups (p = 0.44). A statistically significant difference was found between the number of children of ALS and control groups (p < 0.001), indicating ALS patients had more children than controls. When the number of children is assessed by gender, for women, there was no statistically significant difference between the number of children of ALS and control groups (p = 0.067). Conclusions: This finding supports the view that ALS does not have a negative selection pressure on the patient population's fertility.

Emotional Lability at Disease Onset Is an Independent Prognostic Factor of Faster Disease Progression in Amyotrophic Lateral Sclerosis.

Amyotrophic lateral sclerosis (ALS) is a fast progressing neurodegenerative disease leading to quadriplegia, anarthria and respiratory insufficiency. A large variety of phenotypes and disability progression requires individually tailored management. Identification of predictors of poor prognosis may not only improve management, but also allow for more precise patients' stratification for clinical trials or research studies. The aim of the study was to investigate the influence of emotional lability present at disease onset on ALS progression by exploring its direct impact on the decay of the ALS Functional Rating Scale-Revised (ALSFRS-R). The study was performed in a group of 1145 patients from Germany, Poland, Portugal and Turkey between 2014 and 2018. The analysis showed that the presence of emotional lability at ALS onset was linked to a faster decline of ALSFRS-R (0.70 vs 0.50, p<0.0001), in case of either bulbar (0.80 vs 0.65, p<0.05) or limb disease onset (0.59 vs 0.46, p <0.01). It was most prominent in the bulbar subscore of ALSFRS-R. A multiple regression analysis showed a direct influence of emotional lability at ALS onset on disease progression, regardless of age, gender, site of onset, weight loss, cognitive impairment and diagnosis delay (ß=0.071; p=0.019). It can therefore be concluded that the presence of emotional lability at the disease onset is an independent factor of faster disease progression in ALS.
