RESUMEN
BACKGROUND: The immune response to SARS-CoV-2 virus, the cause of COVID-19, is complex. Antibody mediated responses are important for viral clearance but may also drive hyperinflammation in severe COVID-19. We present a case of an individual with a genetic inability to produce antibodies and severe COVID-19, receiving no other specific anti-viral treatment than convalescent COVID-19 plasma, illustrating that hyperinflammation can occur in the absence of a humoral anti-viral response. In addition, the case illustrates that the assessment of SARS-CoV-2 T cell responses can facilitate clinical decision making in patients with COVID-19 and weak or absent humoral immune responses. CASE PRESENTATION: A male with X-linked agammaglobulinemia on regular immunoglobulin replacement therapy, hospitalized for 35 days due to severe COVID-19. Systemic inflammatory parameters were highly elevated. After treatment with convalescent COVID-19 plasma he became afebrile and the fatigue diminished. He was discharged on day 42 and nasopharyngeal SARS-CoV-2 PCR eventually was negative on day 49. Evidence of SARS-CoV-2 specific T cells prior to administration of plasma therapy suggested that antibodies were crucial for viral clearance. Regular assessment showed robust and persistent SARS-CoV-2 specific T-cell responses after recovery suggested that prophylactic administration of convalescent COVID-19 plasma was unnecessary. CONCLUSION: Assessment of SARS-CoV-2T-cell responses can facilitate the clinical management of COVID-19 patients with humoral immunodeficiencies.

AIM: Advances in technology generate new opportunities to develop e-health tools to help individuals in self-management by assessing symptoms of illness and its relation to treatments. Self-management is central when living with primary immunodeficiency diseases. The aim was to explore the experiences of people living with primary immunodeficiency, who used a pilot version of the web-based health diary. DESIGN: Explorative design. METHODS: In total, 16 participants (median age 59) attended one of three focus groups. Inductive content analysis was used. RESULTS: The participants could be encouraged to discover aspects of their health by contributing to documentation which could support the health concept. A greater understanding about their own health and communicating with healthcare professionals during encounters was expressed. The web-based health diary is a helpful tool to discover aspects of health that affects the individuals' life situation and assists the self-management of a long-term condition such as immunodeficiency.
RESUMEN
AIMS AND OBJECTIVES: To evaluate patient-reported experiences of facilitated subcutaneous immunoglobulin treatment in adults with primary or secondary immunodeficiency. BACKGROUND: Decreased levels of circulating antibodies (humoral immunodeficiency) are often associated with higher infection rates which cause problems in daily living, for example, symptoms of severe and recurrent bacterial infections that may cause chronic lung diseases. For some diagnoses, treatment with immunoglobulin becomes critical and lifelong. The acceptability of administration forms is important to achieve adherence to treatment and to increase quality of life for these patients. DESIGN: Convergent mixed-method approach. METHODS: A structured telephone interview with nine questions evaluated on a score scale about treatment experience, satisfaction and ancillary supplies was used, followed by open-ended questions for each item. RESULTS: Prohibiting factors were revealed, exemplified by problems due to technical issues and ancillary supply issues. Promoting factors were shown by high a satisfaction according to the score-scale when combining treatment with daily life as well as increased well-being. Facilitated subcutaneous immunoglobulin treatment led to fewer treatment sessions, with a time-saving aspect also described by high scores in the item concerning longer treatment interval. CONCLUSIONS: The opportunity to be given the best possible treatment plan adjusted for each patient's situation is central. Healthcare professionals should discuss the different aspects that can promote and inhibit the outcomes of treatment. RELEVANCE TO CLINICAL PRACTICE: The results can help professionals to understand different factors that may impinge on the patients' everyday life when they are forced into a lifelong treatment regimen. This knowledge is also important for nurses who have a responsibility to promote health concerning patients with long-term conditions in general.
