Glycosylated haemoglobin (HbA1c) was measured in 10 patients with iron deficiency anaemia, 10 patients with vitamin B12 deficiency anaemia and 10 healthy controls. Initially there were no significant differences between the groups (P greater than 0.4), but after treatment with iron and vitamin B12 for 3 and 6 weeks, the glycosylated haemoglobin concentration decreased significantly (P less than 0.01). It was concluded that glycosylated haemoglobin is a sensitive marker of the changes in the erythrocyte population that are observed when predominantly immature erythrocytes are being produced.

Patient-reported outcomes (PROs) digitalization and integration into clinical practice has widened its purpose, which makes it relevant to reconceptualize PRO accordingly. Therefore, this study aims to describe and critically discuss the purposes of PRO and to suggest an interdisciplinary definition of PRO aligned with current applications. The findings in this study are based on a formerly conducted scoping review on PRO and patient participation; hence, a sub-study focusing on the purpose of PRO. The purposes of PRO pertain to research and drug testing; quality and economy; patient-centered care; politicization and democratization; and organization and culture. The suggested definition describes PRO as a validated questionnaire; developed in collaboration between patients, clinicians, and other pertinent stakeholders; systematically applied; mediated digitally or paper-based; completed directly by the patient, with assistance or by a qualified proxy; composed of generic, disease-specific, condition-specific or preference-based measures; consisting of content pertaining to the patient’s physical and mental health condition, functioning, symptoms, well-being or health-related quality of life (HRQoL); providing objective and/or subjective outcomes, and individual and/or population data. An alternative understanding of PRO is meant to enhance the link between purposes and definitions of PRO, facilitating interdisciplinary stakeholder discussions on PRO, potentially improving future PRO interventions.

The tissue types, immunoglobulin levels, and the presence of circulating autoantibodies were investigated in 57 children. Fifteen of these children suffered from bronchial asthma and, in addition, had no or very little IgA in their serum and saliva (Group 1 patients). Another fifteen children with asthma but normal immunoglobulin levels in serum and saliva (Group 2 patients), seven patients with selective IgA deficiency but without allergic diseases (Group 3 patients), and twenty healthy children served as controls. Sixty per cent of the Group 1 patients had the phenotype HLA-A1,B8, whereas this tissue type was found only in 27, 14 and 15 per cent, respectively, of the Group 2 and Group 3 patients and the healthy children. Furthermore, high IgM- and IgE levels were observed in most Group 1 patients, and in five of these patients (33 per cent) autoantibodies were present in the serum. In addition, eczema and glomerulonephritis occurred rather frequently in this group of patients. Conversely, normal immunoglobulin levels and absence of circulating autoantibodies were found in the remaining three groups of children. The results emphasize the heterogeneity of the IgA deficiency syndrome, and the question is raised as to whether the tissue type HLA-A1,B8 observed in most Group 1 patients reflects the abnormal immune reactivity of these patients.
