This paradigm of care builds on the foundational ethical principle of patient autonomy, further leveraging beneficence, nonmaleficence, and justice to provide bespoke care in the appropriate clinical setting. When evidence is carefully evaluated together with acceptability and feasibility, equity, cost-effectiveness, resources, and patient preferences, an individualized assessment of the trade-off between possible benefits and harms can optimize patient management. In the setting of a conditional recommendation, it is appropriate to engage in SDM with patient partners, to the extent each patient is willing and able to engage in the SDM process. Three conversations inform SDM and include team talk, option talk, and decision talk with discussion of the plan of care. During these conversations, clear communication strategies that are specific, measurable, achievable, realistic, time sensitive, and provide assessment of absolute (not just relative) risk are important to provide necessary education to patient partners. Follow-up is key to ensure that decisions lead to effective treatment. Through this process, it is necessary to minimize cognitive overload and promote a minimally disruptive medicine approach. The acronym \"HOW\" promotes a holistic appraisal of evidence in context, open-minded teamwork with patients and families, and willingness to be a listening presence while serving as a partner and guide and appreciating the multidimensional and unique nature of each individual. SDM is and will continue to remain a cornerstone of appropriate medical care in settings of clinical equipoise.</p>","PeriodicalId":7646,"journal":{"name":"Allergy and asthma proceedings","volume":"45 6","pages":"398-403"},"PeriodicalIF":2.6,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142612105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients typically present with recurrent sinopulmonary and gastrointestinal infections, and some patients can experience an increased risk of opportunistic infections. Multidisciplinary collaboration is important in the management of patients with primary antibody deficiencies because these patients require heightened monitoring for atopic, autoimmune, and malignant comorbidities and complications. The underlying genetic defects associated with many primary antibody deficiencies have been discovered, but, in some diseases, the underlying genetic defect and inheritance are still unknown. The diagnosis of primary antibody deficiencies is often made through the evaluation of immunoglobulin levels, lymphocyte levels, and antibody responses.

Broadly, immunodeficiencies can be divided into primary immunodeficiency disorders (PIDDs) and secondary immunodeficiency disorders. This review will focus on PIDDs. The overall prevalence for PIDDs is estimated to be ∼1-2% of the population but may be underestimated due to underdiagnosis of these conditions. PIDDs affect males slightly more often than females. The mortality rates differ based on the specific condition but can be extremely high if the condition is left undiagnosed or untreated. The most common causes of death are infections, respiratory complications, and cancers (e.g., lymphoma). Comorbidities and complications include infection, chronic lung disease, granulomatous lymphocytic interstitial lung disease, and autoimmune disorders. The disease burden of patients with common variable immunodeficiency (CVID) is estimated to be greater than patients with diabetes mellitus and chronic obstructive pulmonary disease. PIDDs have a serious impact on the quality of life of the patients, including sleep disturbance, anxiety, and social participation as well as other psychosocial burdens associated with these disorders. The financial cost of PIDDs can be substantial, with the cost of untreated CVID estimated to be $111,053 per patient per year. Indirect costs include productivity loss and time lost due to infusion and hospital visits. Secondary immunodeficiency is not fully discussed in this review but likely contributes equally to the burden of overall immunodeficiency disorders.

The paradoxical nature of this association can be explained by the multiple cells and molecules involved in immune networks that interact with each other in synergistic, redundant, antagonistic, and parallel arrangements. Because progressively more immunodeficiencies are found to have a genetic etiology, in many cases, a monogenic pathology, an understanding of why immunodeficiency is really an immune dysfunction becomes evident. Understanding the role of specific genes allows us to better understand the complete nature of the inborn error of immunity (IEI); the latter is a term generally used when a clear genetic etiology can be discerned. Autoimmune cytopenias, inflammatory bowel disease, autoimmune thyroiditis, and autoimmune liver diseases as well as lymphomas and cancers frequently accompany primary immunodeficiencies, and it is important that the practitioner be aware of this association and to expect that this is more common than not. The treatment of autoimmune or immunodysregulation in primary immunodeficiencies often involves further immunosuppression, which places the patient at even greater risk of infection. Mitigating measures to prevent such an infection should be considered as part of the treatment regimen. Treatment of immunodysregulation should be mechanism based, as much as we understand the pathways that lead to the dysfunction.

The classic complement pathway plays a role in humoral immunity, whereas the alternative and lectin pathways augment the innate response. Impairment, deficiency, or overactivation of any of the known 50 complement proteins may lead to increased susceptibility to infection with encapsulated organisms, autoimmunity, hereditary angioedema, or thrombosis, depending on the affected protein. Classic pathway defects result from deficiencies of complement proteins C1q, C1r, C1s, C2, and C4, and typically manifest with features of systemic lupus erythematosus and infections with encapsulated organisms. Alternative pathway defects due to deficiencies of factor B, factor D, and properdin may present with increased susceptibility to Neisseria infections.
