Quality of Life Differences for Primary Immunodeficiency Patients on Home SCIG versus IVIG.

ABSTRACT:

Background

Patients with primary immunodeficiency disease (PIDD) and antibody deficiency require lifelong immunoglobulin replacement therapy. While both subcutaneous immunoglobulin (SCIG) and intravenous immunoglobulin (IVIG) replacement therapy are effective in preventing infection, patients with PIDD still experience worse health-related quality of life (hrQOL) outcomes.

Objective

Assess differences in hrQOL for PIDD patients receiving home SCIG versus IVIG.

Methods

SF-36 surveys were administered by a specialty pharmacy to 630 PIDD patients receiving home SCIG and IVIG at baseline and then every 3 months between 2014 and 2016. Results were analyzed using two-sample t tests and linear mixed effects model. Analysis was repeated for different age categories and trended over time.

Results

Patients receiving SCIG reported statistically significant higher energy fatigue scores (+ 9 points, p < 0.001) but lower perceived role limitations due to physical health scores (- 14 points, p < 0.001). These differences were only observed in patients > 36 years of age. There were no differences in the composite SF-36 score for patients receiving SCIG versus IVIG (+ 1, p = 0.66). Immunoglobulin-naïve patients all improved their hrQOL, but a larger improvement was seen in those initiating SCIG versus IVIG.

Conclusion

Patients with PIDD on home IVIG versus SCIG have similar composite hrQOL scores as measured by the SF-36. In the adult population, initiating immunoglobulin replacement with SCIG may result in more hrQOL improvement compared with IVIG, although personal preferences should also be considered.

Clinical implications

Patients with PIDD on home IVIG versus SCIG have similar composite health-related quality of life scores as measured by the SF-36. Patients with primary immune-deficiency on home IVIG versus SCIG have similar composite health-related quality of life scores as measured by the SF-36. Personal preferences are important in deciding whether to treat with IVIG or SCIG.

Project description:BackgroundDementia often eventually leads to dependency on others and finally to residential care. However, in Norway about half of the dementia population lives at home, due to individual and political wishes. There is scarce and inconclusive knowledge of how living in a nursing home differs from living at home for persons with dementia (PWDs) with regard to their quality of life (QoL). The first aim of the study was therefore to compare QoL, cognitive and physical functions, social contacts, sleep patterns, physical activity levels, exposure to light, and medication of PWDs in nursing homes and home-dwelling PWDs, and whether living in nursing homes was associated with a lower QoL than living at home for PWDs. A second aim was to examine if possible differences between residencies in QoL were consistent over time.MethodsThe cross-sectional study was based on baseline data from two RCT studies of PWDs. A total of 15 nursing homes with adapted units for PWDs and 23 adapted day care centres for home-dwelling PWDs recruited 78 and 115 participants respectively. Trained nurses scored sociodemographic data, level of dementia (on the Clinical Dementia Rating scale), amount of medication, and QoL (QUALID). Sleep patterns, physical activity levels, and light exposure were measured by actigraphy. A multiple regression analysis was used to test the association between residency and QoL. The association between residency and change in QoL over time was investigated by linear regression analysis of a subsample with follow-up data.ResultsHome-dwelling PWDs showed significantly higher QoL than PWDs in nursing homes. This difference was maintained even after stratifying on the severity of dementia. Home-dwelling PWDs with moderate dementia showed significantly less use of walking aids, more social contact, higher levels of activity and exposure to daylight, and less use of psychotropic medications. The regression model explained 28 % of the variance in QoL in persons with moderate dementia. However, only residency contributed significantly in the model. Residency also significantly predicted negative change over time in QoL.ConclusionThe study indicated that living at home as long as possible is not only desirable for economic or health political reasons but also is associated with higher QoL for persons with moderate dementia. More studies are needed to investigate how QoL could be increased for PWDs in nursing homes.

Project description:BackgroundAlthough COPD is associated with significant health-related quality-of-life (HRQL) impairment, factors influencing HRQL in patients with COPD are not well understood, particularly in African Americans. We hypothesized that HRQL in COPD differs by race and sought to identify factors associated with those differences.MethodsWe analyzed 224 African American and 1,049 Caucasian subjects with COPD enrolled in the COPDGene (Genetic Epidemiology of COPD) Study whose conditions were classified as GOLD (Global Initiative for Chronic Obstructive Lung Disease) stages I to IV. HRQL and symptoms were compared using the St. George Respiratory Questionnaire (SGRQ) and the modified Medical Research Council Dyspnea (MMRC) scale. We constructed a mixed-effects linear regression model for SGRQ score.ResultsAfrican Americans were younger and reported fewer pack-years of smoking, more current smoking, and less attained education than Caucasians; MMRC scores were higher (P = .02) as were SGRQ scores (mean score difference, 8.4; P < .001). In a general linear model of SGRQ total score after adjusting for factors such as age, sex, and pack-years of smoking, SGRQ total score was similar for African Americans and Caucasians who reported no COPD exacerbations in the prior year. However, for subjects with exacerbations, SGRQ total score was increased to a greater relative extent for African Americans than for Caucasians (1.89 points for each exacerbation, P = .006). For hospitalized exacerbations, the effect on SGRQ total score also was greater for African Americans (4.19 points, P = .04). Furthermore, a larger percentage of African Americans reported having had at least one exacerbation that required hospitalization in the prior year (32% vs 16%, P < .001).ConclusionIn analyses that account for other variables that affect quality of life, HRQL is similar for African Americans and Caucasians with COPD without exacerbations but worse for African Americans who experience exacerbations, particularly hospitalized exacerbations.
