Recent development on the use of sublingual immunotherapy tablets for allergic rhinitis.

OBJECTIVE: Allergic rhinitis (AR) is an immunoglobulin (Ig) E-mediated inflammatory condition that causes sneezing, nasal congestion, rhinorrhea, and nasal itch. Although subcutaneous immunotherapy for the treatment of AR has been in use and well established as a treatment modality, sublingual immunotherapy (SLIT) is increasingly considered to be the safer and more convenient alternative. Thus, the objective of this review is to describe recent findings pertaining to the use of SLIT tablets (SLIT-T) for AR. DATA SOURCES: A database search (PubMed.gov) for articles published between January 1, 2017, and February 9, 2021, was conducted using the following key words: "allergic rhinitis," AND-ed "sublingual immunotherapy." Included were randomized placebo-controlled trials. Other experimental design studies were excluded. STUDY SELECTIONS: A total of 11 randomized placebo-controlled trials were selected for full-text review and included in the analysis. All studies investigated the use of SLIT on patients with seasonal AR (4 tree pollen, 1 grass pollen, and 1 Japanese cedar) or perennial AR (3 house dust mite). RESULTS: Our review of 7 recently published randomized placebo-controlled trials with 2348 subjects receiving SLIT reported increased efficacy, safety, supportive immunologic parameters (IgE and IgG4 pre- and posttreatment levels), and improved quality of life. All studies excluded subjects with overlapping seasonal or perennial allergens, a history of moderate-to-severe uncontrolled asthma, or reduced lung function. CONCLUSION: Our review highlights that SLIT is a safe and effective treatment that considerably reduces symptoms and medication requirements in AR and improves quality of life.

Experiences of integrating community volunteers as extensions of the primary care team to help support older adults at home: a qualitative study.

BACKGROUND: Increasing the integration of community volunteers into primary health care delivery has the potential to improve person-focused, coordinated care, yet the use of volunteers in primary care is largely unexplored. Health Teams Advancing Patient Experience: Strengthening Quality (Health TAPESTRY) is a multi-component intervention involving trained community volunteers functioning as extensions of primary care teams, supporting care based on older adults' health goals and needs. This study aimed to gain an understanding of volunteer experiences within the program and client and health care provider perspectives on the volunteer role. METHODS: This study used a qualitative descriptive approach embedded in a pragmatic randomized controlled trial. Participants included Health TAPESTRY volunteers, health care providers, volunteer coordinator, and program clients, all connected to two primary care practice sites in a large urban setting in Ontario, Canada. Data collection included semi-structured focus groups and interviews with all participants, and the completion of a measure of attitudes toward older adults and self-efficacy for volunteers. Qualitative data were inductively coded and analyzed using a constant comparative approach. Quantitative data were summarized using descriptive statistics. RESULTS: Overall, 30 volunteers and 64 other participants (clients, providers, volunteer coordinator) were included. Themes included: 1. Volunteer training: "An investment in volunteers"; 2. Intergenerational volunteer pairing: "The best of both worlds"; 3. Understanding the volunteer role and its scope: "Lay people involved in care"; 4. Volunteers as extensions of primary care teams: "Being the eyes where they live"; 5. The disconnect between volunteers and the clinical team: "Is something being done?"; 6. "Learning… all the time": Impacts on volunteers; and 7. Clients' acceptance of volunteers. CONCLUSIONS: This study showed that it is possible to integrate community volunteers into the primary care setting, adding human connections to deepen the primary care team's understanding of their patients. Program implementation suggestions that emerged included: using role play in training, making volunteer role boundaries and specifications clear, and making efforts to connect volunteers and the primary care team they are supporting. This exploration of stakeholder voices has the potential to help improve volunteer program uptake and acceptability, as well as volunteer recruitment, retention, and training.
