Bril V, Lampe J, Cooper N, Kiessling P, Gardulf A. Patient-reported preferences for subcutaneous or intravenous administration of parenteral drug treatments in adults with immune disorders: a systematic review and meta-analysis. J Comp Eff Res 2024; 13:e230171. [PMID: 39115099 PMCID: PMC11363182 DOI: 10.57264/cer-2023-0171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Accepted: 07/16/2024] [Indexed: 08/27/2024] Open
Abstract
Aim: Several studies have found subcutaneous (SC) and intravenous (IV) administration of similar drugs for long-lasting immunological and autoimmune diseases to have similar clinical effectiveness, meaning that what patients report they prefer is, or should be, a major factor in treatment choices. Therefore, it is important to systematically compile evidence regarding patient preferences, treatment satisfaction and health-related quality of life (HRQL) using SC or IV administration of the same drug. Materials & methods: PubMed database searches were run on 15 October 2021. Studies involving patients with experience of both home-based SC and hospital-based IV administration of immunoglobulins or biological therapies for the treatment of any autoimmune disease or primary immunodeficiencies (PIDs) were included. The outcomes assessed were patient preferences, treatment satisfaction and HRQL. Preference data were meta-analyzed using a random-effects model. Results: In total, 3504 citations were screened, and 46 publications describing 37 studies were included in the review. There was a strong overall preference for SC over IV administration, with similar results seen for PIDs and autoimmune diseases: PID, 80% (95% confidence interval [CI], 64-94%) preferred SC; autoimmune diseases, 83% (95% CI: 73-92%); overall, 82% (95% CI: 75-89%). The meta-analysis also found that 84% (95% CI: 75-92%) of patients preferred administration at home to treatment in hospital. Analysis of treatment satisfaction using the life quality index found consistently better treatment interference and treatment setting scores with SC administration than with IV administration. Conclusion: Compared with IV infusions in hospital, patients tend to prefer, to be more satisfied with and to report better HRQL with SC administration of the same drug at home, primarily due to the greater convenience. This study contributes to evidence-based care of patients with autoimmune diseases or PIDs.

Subcutaneous immunoglobulins (SCIG) for chronic inflammatory demyelinating polyneuropathy (CIDP): A comprehensive systematic review of clinical studies and meta-analysis. Neurol Sci 2024:10.1007/s10072-024-07640-3. [PMID: 38937399 DOI: 10.1007/s10072-024-07640-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Accepted: 06/05/2024] [Indexed: 06/29/2024]
Abstract
BACKGROUND Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) presents significant treatment challenges due to its chronic nature, varied clinical presentations, and rarity. Subcutaneous immunoglobulin (SCIG) has emerged as a maintenance therapy, offering potential advantages in administration and patient experience over the previously recognized intravenous immunoglobulin (IVIG). METHODS We included all clinical studies involving CIDP patients treated with SCIG from eleven databases up to March 2024. RESULTS 50 clinical studies were included in the systematic review, with 22 involved in the meta-analysis. These studies offer clinical data on around 1400 CIDP patients. Almost all studies considered SCIG a maintenance therapy, with the majority of results suggesting it as a viable substitute that may offer comparable or enhanced advantages. Studies covered aspects such as efficacy, safety, quality of life, practicality, economic evaluation, and patient preference. Meta-analysis showed SCIG significantly improved muscle strength and sensory function, had fewer and milder side effects, reduced relapse rates, and received a strong preference. CONCLUSIONS Findings suggest that SCIG for CIDP maintenance not only provides a more feasible alternative, with economic evaluations showing considerable cost reductions over time, and patient preference for SCIG being pronounced, but may also deliver comparable or superior health outcomes. Ongoing research lines on formulations, techniques, and direct comparative studies are critical to further illuminate, enhance, and expand SCIG's role in treatment.

Abstract
OBJECTIVE Existing healthcare systems face finite resource allocation and budgetary constraints, resulting in a substantial need for innovative solutions to enhance service delivery at reduced costs. A novel, user-friendly on-body delivery system (OBDS) was developed which enables administration of large-volume subcutaneous (SC) drugs in both clinical and home-based settings (at-home healthcare professional [HCP] administration or at-home self-administration). METHODS This research sought to evaluate the potential economic impact of at-home self- or HCP- administration with the OBDS through a comprehensive review of published literature and semi-structured interviews with 17 US payers representing approximately 227 million covered lives. RESULTS Published literature on OBDS remains limited, but available research highlights the cost-savings of SC administration due to reduced healthcare resource utilization, particularly with home-based care, and improved patient compliance. In interviews, payers identified several attributes that would help address unmet clinical and economic needs. Clinically, the hidden needle and ease-of-use compared to SC syringe pumps was deemed valuable to improve patient compliance and, as OBDS required minimal training, reduce the risk of administration errors. The flexibility to administer drugs at home (self-administration or HCP-administration) or in-clinic was identified as the most impactful attribute on coverage decision making as it has the greatest potential to reduce costs associated with HCP administration for several therapeutic areas. CONCLUSIONS Given the ability to help address critical unmet needs for the patient and healthcare system, a large proportion of the payers stated that the novel OBDS would warrant a price premium versus the cost of the standalone SC vial and certainly over the IV counterpart. Future research to quantify the value that OBDS efficiencies could bring to healthcare delivery are warranted.

Abstract
BACKGROUND Documentation of pharmacists' activities, such as drug related problems (DRPs) management, is necessary to estimate fair remuneration but is rarely done in community pharmacies. OBJECTIVE To document and evaluate the evolution of DRPs prevalence and management over six years. METHODS Observational study carried out since 2016 in a community pharmacy. Documentation was made yearly for 21 days (depending on seasons, holidays and medical internship rotations) using the ClinPhADoc tool. Pharmacists documented: medication, DRP type, intervention, implied partner and time for DRP management. A subanalysis was made depending on the medical rotation. RESULTS A total of 171 437 prescriptions were received and 6 844 (4.0%) documented with 1 550 DRPs. Most frequent DRPs were procedural (n = 506, 32.6%), dosage/posology (n = 263, 17.0%) and drug-drug interaction (n = 153, 9.9%). Mean time dedicated to DRP management was 6.9 min, the longest time was for clinical DRPs (11.0 min, SD = 6.6). Most DRPs (n = 726, 44.6%) were managed by the pharmacist alone taking less working time than when involving other stakeholders (p < 0.01). Statistically significant differences were found in DRPs between the beginning and end of medical rotation (p < 0.05). CONCLUSIONS Documentation of DRP management allowed consistent results over the years. Patterns of DRPs can be used to develop inter-professional interventions to prevent DRPs.

Anti-Inflammatory and Immunomodulatory Effect of High-Dose Immunoglobulins in Children: From Approved Indications to Off-Label Use. Cells 2023; 12:2417. [PMID: 37830631 PMCID: PMC10572613 DOI: 10.3390/cells12192417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 09/23/2023] [Accepted: 10/05/2023] [Indexed: 10/14/2023] Open
Abstract
BACKGROUND The large-scale utilization of immunoglobulins in patients with inborn errors of immunity (IEIs) since 1952 prompted the discovery of their key role at high doses as immunomodulatory and anti-inflammatory therapy, in the treatment of IEI-related immune dysregulation disorders, according to labelled and off-label indications. Recent years have been dominated by a progressive imbalance between the gradual but constant increase in the use of immunoglobulins and their availability, exacerbated by the SARS-CoV-2 pandemic. OBJECTIVES To provide pragmatic indications for a need-based application of high-dose immunoglobulins in the pediatric context. SOURCES A literature search was performed using PubMed, from inception until 1st August 2023, including the following keywords: anti-inflammatory; children; high dose gammaglobulin; high dose immunoglobulin; immune dysregulation; immunomodulation; immunomodulatory; inflammation; intravenous gammaglobulin; intravenous immunoglobulin; off-label; pediatric; subcutaneous gammaglobulin; subcutaneous immunoglobulin. All article types were considered. IMPLICATIONS In the light of the current imbalance between gammaglobulins' demand and availability, this review advocates the urgency of a more conscious utilization of this medical product, giving indications about benefits, risks, cost-effectiveness, and administration routes of high-dose immunoglobulins in children with hematologic, neurologic, and inflammatory immune dysregulation disorders, prompting further research towards a responsible employment of gammaglobulins and improving the therapeutical decisional process.

Abstract
BACKGROUND Home health care delivery is projected to increase. Intravenous immunoglobulin (IVIG) therapy has high potential to move from the outpatient hospital (OPH) setting to home delivery. OBJECTIVE This study examined the relationship between home and OPH IVIG infusions and health care utilization. METHODS We used a retrospective cohort study design and the Humana Research Database to identify patients with 1 or more medical or pharmacy claims for an IVIG infusion agent from January 1, 2017, to December 31, 2018. Eligible patients were enrolled in a Medicare Advantage Prescription Drug (MAPD) or commercial health plan, with at least 12 months of continuous enrollment before and after their first infusion (i.e., index date) received in the home or OPH setting. We measured the odds of experiencing an inpatient (IP) stay or emergency department (ED) visit, adjusted for baseline differences in age, sex, race, region, population density, low-income, and dual eligibility status, MAPD or commercial health plan, plan type, treatment-naïve status, home health use, RxRisk-V comorbidity burden score, and indications for IVIG use. RESULTS A total of 208 and 1079 patients received IVIG infusions in the home and OPH setting, respectively. The odds for an IP stay (odds ratio [OR] 0.56 [95% CI 0.38-0.82]) and ED visit (OR 0.62 [95% CI 0.41-0.93]) were significantly lower in patients who received IVIG infusion in the home than patients receiving infusion in the OPH setting. CONCLUSIONS Our findings suggest there may be value to increasing referrals for IVIG home infusion. Decreased health care utilization provides value to the system in cost savings and to patients and families owing to less disruption and improved clinical outcomes. Further study can help inform health policy designed to maximize the benefits of IVIG home infusion while minimizing potential risks.

Abstract
BACKGROUND Enzyme replacement therapy (ERT) with alglucosidase alfa is the treatment for patients with Pompe disease, a hereditary metabolic myopathy. Home-based ERT is unavailable in many countries because of the boxed warning alglucosidase alfa received due to the risk of infusion-associated reactions (IARs). Since 2008, home infusions have been provided in The Netherlands. OBJECTIVES This study aimed to provide an overview of our experience with home-based infusions with alglucosidase alfa in adult Pompe patients, focusing on safety, including management of IARs. METHOD We analysed infusion data and IARs from adult patients starting ERT between 1999 and 2018. ERT was initially given in the hospital during the first year. Patients were eligible for home treatment if they were without IARs for multiple consecutive infusions and if a trained home nurse, with on-call back-up by a doctor, was available. The healthcare providers graded IARs. RESULTS We analysed data on 18,380 infusions with alglucosidase alfa in 121 adult patients; 4961 infusions (27.0%) were given in hospital and 13,419 (73.0%) were given at home. IARs occurred in 144 (2.9%) hospital infusions and 113 (0.8%) home infusions; 115 (79.9% of 144) IARs in hospital and 104 (92.0% of 113) IARs at home were mild, 25 IARs (17.4%) in hospital and 8 IARs (7.1%) at home were moderate, and very few severe IARs occurred (4 IARs in hospital [2.8%] and 1 IAR at home [0.9%]). Only one IAR in the home situation required immediate clinical evaluation in the hospital. CONCLUSION Given the small numbers of IARs that occurred with the home infusions, of which only one was severe, we conclude that alglucosidase alfa can be administered safely in the home situation, provided the appropriate infrastructure is present.

Abstract
BACKGROUND Pompe disease is a lysosomal storage disease treated with life-long enzyme replacement therapy (ERT). Home-based ERT has been provided in the Netherlands since 2008 because it diminishes the burden of treatment, increases patient flexibility and autonomy, and is thus a more patient-centred approach to ERT. METHODS All Dutch Pompe patients receiving alglucosidase alfa infusions at home were approached to participate in a questionnaire to validate the safety of home-based ERT. Prospective data on symptoms occurring during or within 48 h after infusion and retrospective data on infusion associated reactions (IARs) in the last three months were collected four times during one year. RESULTS In total, 116 out of 120 eligible patients (17 classic infantile, 2 atypical infantile, 15 childhood onset and 82 adult) filled out 423 questionnaires (response rate: 88.1%). Symptoms during or after infusion were reported 27 times in 17 patients. Fatigue was the most commonly reported health complaint (in 9.5% of patients). Four health complaints were judged to be IARs and reported to the Erasmus MC University Medical Center. None of the IARs reported in this study warranted emergency clinical care. CONCLUSIONS Our data demonstrate that home-based ERT in Pompe disease can be safely implemented as few, mostly mild, symptoms were reported during or after infusion. Insights from this study can be used as a base for implementing home-based ERT in other countries and to further optimize patient care, as unreported mild symptoms do not pose a health risk but may still be relevant to the patient.

Abstract
Owing to the rising popularity and demand for immunoglobulins (IgG), obtaining supplies and rationalizing IgG use have become challenging. Herein, IgG consumption in Poland was analyzed through total IgG use and number of patients reported to the National Health Fund between 1 January 2016 and 31 December 2020. Total IgG used within 5 years increased by 27.48%, IgG use/1000 inhabitants/year was 23.13 g (2016) and 29.61 g (2020). In 2020, 35.5 % of IgG used was for neurological conditions, 25% for primary immunodeficiencies (PID), and 39.3% for all other indications. Within 5 years, 1,121,168.75 g IgG was used in PID; the use increased by 72%, from 783 in 2016 to 1153 patients in 2020. The proportion of patients who received subcutaneous immunoglobulin (SCIG) replacement therapy (IgRT) increased to 78% (2020). Within 5 years, 1,783,534.81 g IgG was used in neurological drug programs (+42.44%) and 2,327,513.88 g (+1.25%) outside neurological indications and outside PID. The annual IgG amount decreased in adult anesthesiology and intensive care (-46%), internal medicine (-55%), pneumonology (-50%), pediatric clinical immunology (-50%), and gynecology and obstetrics (-48%) and increased in dermatology (+178%), rheumatology (+103%), and clinical transplantation (+82%). IgG use significantly increased in Poland, mostly owing to PID. Subcutaneous IgG administration is currently the most common mode of IgRT in PID patients. An increase in SCIG administration may be expected for other indications. Implementing evidence-based clinical guidelines is key to prioritizing and rationalizing IgG use for immunomodulatory indications and secondary immune deficiencies.

Transfus Med 2022; 32:410-421. [PMID: 35751376 PMCID: PMC9795925 DOI: 10.1111/tme.12889] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 05/02/2022] [Accepted: 05/13/2022] [Indexed: 12/30/2022]
Abstract
OBJECTIVES To explore the current and future demand of immunoglobulins globally and specifically for the Netherlands by assessing: (I) which specialties contribute to current demand, (II) new areas of medical need, (III) which transformational factors may impact demand and to what effect, by using a scenario approach. BACKGROUND As immunoglobulin demand continues to increase globally, there is concern of increasing shortages and questions of whether and how future demand will continue based on medical need. METHODS/MATERIALS In line with scenario principles, a scoping review of Pubmed, Web of Science, Embase and Cochrane and grey literature was conducted. Semi-structured interviews with subject matter experts were held. The results of the review and interviews were analysed for major themes. RESULTS The scoping review resulted in 97 articles, 74 regarding clinical uses, and 23 regarding organisational and other themes. Fifteen clinical and non-clinical experts were interviewed. I) Neurology, immunology, and haematology were specialties that contribute most to current demand. II) Regarding potential new areas of medical need, the literature review resulted in more indications than the interviews, for example, post-renal transplants. III) Four groups of key transformational factors were found: factors that could increase immunoglobulin demand (e.g., EMA revisions), decrease demand (e.g., replacement products, Dutch Transfer Act 2021), factors that remain to be seen how it impacts demand (e.g., further evidence), and miscellaneous factors (e.g., supply-related). CONCLUSION Having identified the specialties and relevant transformational factors that affect immunoglobulin demand, more research is needed on what clinical or organisational strategies would be effective in controlling demand in general for the Netherlands and abroad. Other blood establishments may also use a scenario approach to increase preparedness for future (un)expected developments.

[PMID: 34260074 PMCID: PMC8457117 DOI: 10.1002/mus.27356] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 06/11/2021] [Accepted: 06/15/2021] [Indexed: 12/15/2022]
Abstract
Immunoglobulin G (IgG) therapy is an established long‐term treatment in chronic inflammatory demyelinating polyneuropathy (CIDP) that is commonly administered intravenously (IVIg). The subcutaneous immunoglobulin (SCIg) administration route is a safe and effective alternative option, approved by the United States Food and Drug Administration (FDA) in 2018, for maintenance treatment of adults with CIDP. Physicians and patients alike need to be aware of all their treatment options in order to make informed decisions and plan long‐term treatment strategies. In this review, we collate the evidence for SCIg in CIDP from all published studies and discuss their implications and translation to clinical practice. We also provide guidance on the practicalities of how and when to transition patients from IVIg to SCIg and ongoing patient support. Evidence suggests that IVIg and SCIg have comparable long‐term efficacy in CIDP. However, SCIg can provide additional benefits for some patients, including no requirement for venous access or premedication, and reduced frequency of systemic adverse events. Local‐site reactions are more common with SCIg than IVIg, but these are mostly well‐tolerated and abate with subsequent infusions. Data suggest that many patients prefer SCIg following transition from IVIg. SCIg preference may be a result of the independence and flexibility associated with self‐infusion, whereas IVIg preference may be a result of familiarity and reliance on a healthcare professional for infusions. In practice, individualizing maintenance dosing based on disease behavior and determining the minimally effective IgG dose for individuals are key considerations irrespective of the administration route chosen.
