The aim of the present study was to analyze the progression of non-motor symptoms (NMS) burden in Parkinson's disease (PD) patients regarding the development of motor fluctuations (MF).
PD patients ...without MF at baseline, who were recruited from January 2016 to November 2017 (V0) and evaluated again at a 2-year follow-up (V2) from 35 centers of Spain from the COPPADIS cohort, were included in this analysis. MF development at V2 was defined as a score ≥ 1 in the item-39 of the UPDRS-Part IV, whereas NMS burden was defined according to the Non-motor Symptoms Scale (NMSS) total score.
Three hundred and thirty PD patients (62.67 ± 8.7 years old; 58.8% males) were included. From V0 to V2, 27.6% of the patients developed MF. The mean NMSS total score at baseline was higher in those patients who developed MF after the 2-year follow-up (46.34 ± 36.48 vs. 34.3 ± 29.07;
= 0.001). A greater increase in the NMSS total score from V0 to V2 was observed in patients who developed MF (+16.07 ± 37.37) compared to those who did not develop MF (+6.2 ± 25.8) (
= 0.021). Development of MF after a 2-year follow-up was associated with an increase in the NMSS total score (β = 0.128;
= 0.046) after adjustment to age, gender, years from symptoms onset, levodopa equivalent daily dose (LEDD) and the NMSS total score at baseline, and the change in LEDD from V0 to V2.
In PD patients, the development of MF is associated with a greater increase in the NMS burden after a 2-year follow-up.
Background and Objective
Caregiver burden in Parkinson's disease (PD) has been studied in many cross‐sectional studies but poorly in longitudinal ones. The aim of the present study was to analyze the ...change in burden, strain, mood, and quality of life (QoL) after a 2‐year follow‐up in a cohort of caregivers of patients with PD and also to identify predictors of these changes.
Patients and Methods
PD patients and their caregivers who were recruited from January/2016 to November/2017 from 35 centers of Spain from the COPPADIS cohort were included in the study. They were evaluated again at 2‐year follow‐up. Caregivers completed the Zarit Caregiver Burden Inventory (ZCBI), Caregiver Strain Index (CSI), Beck Depression Inventory‐II (BDI‐II), and EUROHIS‐QOL 8‐item index (EUROHIS‐QOL8) at baseline (V0) and at 2‐year follow‐up (V2). General linear model repeated measure and lineal regression models were applied.
Results
Significant changes, indicating an impairment, were detected on the total score of the ZCBI (p < 0.0001), CSI (p < 0.0001), BDI‐II (p = 0.024), and EUROHIS‐QOL8 (p = 0.002) in 192 PD caregivers (58.82 ± 11.71 years old; 69.3% were females). Mood impairment (BDI‐II; β = 0.652; p < 0.0001) in patients from V0 to V2 was the strongest factor associated with caregiver's mood impairment after the 2‐year follow‐up. Caregiver's mood impairment was the strongest factor associated with an increase from V0 to V2 on the total score of the ZCBI (β = 0.416; p < 0.0001), CSI (β = 0.277; p = 0.001), and EUROHIS‐QOL (β = 0.397; p = 0.002).
Conclusion
Burden, strain, mood, and QoL were impaired in caregivers of PD patients after a 2‐year follow‐up. Mood changes in both the patient and the caregiver are key aspects related to caregiver burden increase.
Key points
The present study is, to date, the largest prospective longitudinal study conducted for analyzing how burden, strain, mood, and quality of life change (QoL) in the principal caregiver of a patient with Parkinson's disease (PD).
After 2 years of follow‐up, the status of the principal caregiver of a patient with PD worsens as a whole with an increase in burden and stress and a worsening in mood and QoL.
Mood changes in the patient and in the caregiver as well are key aspects related to increase in caregiver burden.
These findings suggest that it could be essential to detect depressive symptoms both in the patient and in the caregiver too.
Constipation has been linked to cognitive impairment development in Parkinson's disease (PD).
Our aim was to analyze cognitive changes observed in PD patients and controls from a Spanish cohort with ...regards to the presence or not of constipation.
PD patients and controls recruited from 35 centers of Spain from the COPPADIS cohort from January 2016 to November 2017 were followed-up during 2 years. The change in cognitive status from baseline (V0) to 2-year follow-up was assessed with the PD-CRS (Parkinson's Disease Cognitive Rating Scale). Subjects with a score ≥1 on item 21 of the NMSS (Non-Motor Symptoms Scale) at baseline (V0) were considered as "with constipation". Regression analyses were applied for determining the contribution of constipation in cognitive changes.
At V0, 39.7% (198/499) of PD patients presented constipation compared to 11.4% of controls (14/123) (p < 0.0001). No change was observed in cognitive status (PD-CRS total score) neither in controls without constipation (from 100.24±13.72 to 100.27±13.68; p = 0.971) and with constipation (from 94.71±10.96 to 93.93±13.03; p = 0.615). The PD-CRS total score decreased significantly in PD patients with constipation (from 89.14±15.36 to 85.97±18.09; p < 0.0001; Coehn's effect = -0.35) compared to patients without constipation (from 93.92±15.58 to 93.14±17.52; p = 0.250) (p = 0.018). In PD patients, to suffer from constipation at V0 was associated with a decrease in the PD-CRS total score from V0 to V2 (β= -0.1; 95% CI, -4.36 - -0.27; p = 0.026) and having cognitive impairment at V2 (OR = 1.79; 95% CI, 1.01 - 3.17; p = 0.045).
Constipation is associated with cognitive decline in PD patients but not in controls.
Background
Detection of suicidal ideation (SI) is key for trying to prevent suicide. The aim of this study was to analyze the frequency of SI and related factors in Spanish people with Parkinson's ...Disease (PwPD) and to compare them with a control group.
Methods
PD patients and controls recruited from the Spanish cohort COPPADIS from January 2016 to November 2017 were included. Two visits were conducted: V0 (baseline); V2 (2‐year ± 1 month follow‐up). SI was defined as a score ≥1 on item nine of the Beck Depression Inventory‐II (BDI‐II). Regression analyses were conducted to identify factors related to SI.
Results
At baseline, 693 PwPD (60.2% males; 62.59 ± 8.91 years old) and 207 controls (49.8% males; 60.99 ± 8.32 years old) were included. No differences between PwPD and controls were detected in SI frequency at either V0 (5.1% 35/693 vs. 4.3% 9/207; p = 0.421) or at V2 (5.1% 26/508 vs. 4.8% 6/125; p = 0.549). Major depression (MD) and a worse quality of life were associated with SI at both visits in PwPD: V0 (MD, OR = 5.63; p = 0.003; PDQ‐39, OR = 1.06; p = 0.021); V2 (MD, OR = 4.75; p = 0.027; EUROHIS‐QOL8, OR = 0.22; p = 0.006). A greater increase in the BDI‐II total score from V0 to V2 was the only factor predicting SI at V2 (OR = 1.21; p = 0.002) along with an increase in the total number of non‐antiparkinsonian drugs (OR = 1.39; p = 0.041).
Conclusion
The frequency of SI (5%) in PwPD was similar to in controls. Depression, a worse quality of life, and a greater comorbidity were related to SI.
Key points
This study detected suicidal ideation in about 5% of people with Parkinson's disease (PwPD) and was not more frequent than in controls.
Independent factors associated with suicidal ideation were major depression, a worse quality of life, and an increase in mood impairment or comorbidity over time.
These findings suggest the importance of detecting depressive symptoms in PwPD and evaluation for suicide thoughts, especially in those PwPD with major depression.
Quality of life (QOL) plays an important role in independent living in Parkinson's disease (PD) patients, being crucial to know what factors impact QoL throughout the course of the disease. Here we ...identified predictors of QoL impairment in PD patients from a Spanish cohort. PD patients recruited from 35 centers of Spain from the COPPADIS cohort from January 2016, to November 2017, were followed up during 2 years. Health-related QoL (HRQoL) and global QoL (GQoL) were assessed with the 39-item Parkinson's disease Questionnaire (PDQ-39) and the EUROHIS-QOL 8-item index (EUROHIS-QOL8), respectively, at baseline (V0) and at 24 months ± 1 month (V2). Clinically significant QoL impairment was defined as presenting an increase (PDQ-39SI) or decrement (EUROHIS-QOL8) at V2 ≥ 10% of the score at baseline (V0). A comparison with a control group was conducted for GQoL. GQoL did not change significantly in PD patients (N = 507; p = 0.686) or in the control group (N = 119; p = 0.192). The mean PDQ-39SI was significantly increased in PD patients (62.7 ± 8.5 years old; 58.8% males; N = 500) by 21.6% (from 16.7 ± 13 to 20.3 ± 16.4; p < 0.0001) at V2. Ninety-three patients (18.6%) presented a clinically significant HRQoL impairment at V2. To be younger (OR = 0.896; 95% CI 0.829-0.968; p = 0.006), to be a female (OR = 4.181; 95% CI 1.422-12.290; p = 0.009), and to have a greater increase in BDI-II (Beck Depression Inventory-II) (OR = 1.139; 95% CI 1.053-1.231; p = 0.001) and NMSS (Non-Motor Symptoms Scale) (OR = 1.052; 95% CI 1.027-1.113; p < 0.0001) total scores from V0 to V2 were associated with clinically significant HRQoL impairment at the 2-year follow-up (Hosmer-Lemeshow test, p = 0.665; R
= 0.655). An increase in ≥5 and ≥10 points of BDI-II and NMSS total score at V2 multiplied the probability of presenting clinically significant HRQoL impairment by 5 (OR = 5.453; 95% CI 1.663-17.876; p = 0.005) and 8 (OR = 8.217; 95% CI, 2.975-22.696; p = 0.002), respectively. In conclusion, age, gender, mood, and non-motor impairment were associated with clinically significant HRQoL impairment after the 2-year follow-up in PD patients.
•Maternal anti-Toxoplasma IgG2 and IgG3 antibodies diagnose congenital transmission.•Maternal anti-Toxoplasma IgG3 is associated with T. gondii severe congenital disease.•Maternal anti-Toxoplasma ...IgG1 and IgG3 are associated with disseminated disease in the offspring.
Toxoplasma gondii can be transmitted vertically during pregnancy and may cause neurological, ocular, and even systemic damage to the offspring. Congenital toxoplasmosis (CT) can be diagnosed during gestation and/or after birth in the postnatal period. The timely diagnosis is highly relevant for efficient clinical management. The most common laboratory methods for diagnosing CT are based on Toxoplasma-specific humoral immune responses. However, these methods are of low sensitivity or specificity. In a previous study with a small number of cases, the comparison of anti-T. gondii IgG subclasses between mothers and their offspring showed promising results for CT diagnosis and prognosis. Thus, in this work, we analyzed specific IgG subclasses and IgA in 40 T. gondii-infected mothers and their children, of which 27 were congenitally infected and 13 uninfected. A higher frequency of anti-Toxoplasma IgG2, IgG3, IgG4, and IgA antibodies was observed in mothers and congenitally infected offspring. Of these, IgG2 or IgG3 were statistically the most conspicuous. In the CT group, maternal IgG3 antibodies were significantly associated with severe disease of the infants and IgG1 and IgG3 with disseminated disease. The results support that maternal anti-T. gondii IgG3, IgG2 and IgG1 are markers of congenital transmission and severity/spread of disease in the offspring.
