- Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.522.7) and 16.5 cm (13.319.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries.

- OBJECTIVE.: To quantify immunoglobulin and C1q on circulating cell-derived microparticles (MPs) in systemic lupus erythematosus (SLE) and to correlate this with clinical and serological parameters. METHODS.: Sixty-eight clinically well-characterized SLE patients, 38 healthy controls (HC), 6 systemic sclerosis (SSc), and 6 rheumatoid arthritis (RA) patients were included. The numbers of annexin V-binding MPs displaying IgG, IgM or C1q were enumerated by flow cytometry. MP protein levels were determined by mass spectrometry in clinically defined subsets of SLE patients and controls. The MP-IgG load was determined by flow cytometry of all SLE and HC samples. RESULTS.: SLE patients had significantly increased total and relative numbers of IgG-positive MPs (p = 0.0004) with a much higher average IgG-load/MP (p < 0.0001) than HCs. Quantitative mass spectrometry of purified MPs verified significantly increased IgG, IgM, and C1q in SLE. In RA and SSc the average IgG/MP was significantly lower than in SLE (p = 0.006 and 0.05, respectively). Also, IgM/MP and C1q/MP were higher in SLE than in controls (p < 0.05) except for IgM in the RA-group. IgG-positive MPs were significantly associated with the presence of anti-dsDNA, anti-ENA, and anti-histone antibodies, with total IgG, and with decreased leukocyte counts. Average IgG/MP was associated with lower concentrations of MPs, the presence of anti-C1q antibodies, and with complement consumption. CONCLUSIONS.: Circulating cell-derived MPs in SLE carry increased loads of IgG, IgM, and C1q and IgG-MPs are associated with autoantibodies and complement activation. The findings link immunological reactions on MPs with the etiopathology of SLE. © 2012 American College of Rheumatology.

Efficient evaluation of humoral immune responses by the use of serum pools

Tidskriftsartikel (refereegranskat)abstract
- Background: Collection and testing of individual serum samples are often used in research to gain knowledge about e.g. the humoral response against bacteria or virus. This is a valid but time-consuming method and might be a waste of valuable serum samples for inefficient research. So far, no study has considered using serum pools as a quick and efficient screening method to confirm or deny hypotheses. Methods: We created serum pools from four different patient groups (systemic lupus erythematosus n = 85, rheumatoid arthritis n = 77, Sjögren's syndrome n = 91, systemic sclerosis n = 66) and one healthy control group (n = 67). Each serum pool was analyzed using three well-known immunoassays: enzyme-linked immunosorbent assay (ELISA), line blot, and immunofluorescence microscopy (anti-nuclear antibody (ANA) screening). The presence of Epstein-Barr virus (EBV) EA/D-, EBNA-1-, VCA p23-, and gp350-directed antibodies was used to validate serum pools as an efficient tool for further investigations by comparison to previous findings in this area. Results: The presence of EBV EA/D-, EBNA-1-, VCA p23-, and gp350-directed antibodies in each pool was consistent within the obtained ELISA and line blot results, as increased titers of IgG against the four antigens were found in all patient serum pools and also in individual sera regarding gp350. These results correspond to previous findings on individual samples from patients with these diseases. The presence of ANAs was observed in all four patient serum pools and not in the HC pool by both line blots and immunofluorescence microscopy, which corresponds with the expectations and further corroborate the application of serum pools for screenings. Conclusion: We developed and validated the use of serum pools that reliably and rapidly can confirm or deny hypotheses, which enables a more efficient research concentrating on the most evident factors.

Increased antibody levels to stage-specific Epstein–Barr virus antigens in systemic autoimmune diseases reveal a common pathology

- The immune responses to antigens from different stages of the Epstein–Barr virus (EBV) life cycle were investigated in systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), Sjögren’s syndrome (SS), and systemic sclerosis (SSc) to gain knowledge of EBV’s involvement in the etiology of systemic autoimmune diseases (SADs) and for an overview of the humoral immune responses against EBV. Investigations were performed by the use of ELISA. IgM, IgA, and IgG antibody binding to 11 EBV antigens: EBNA1, EBNA2, BALF5, EAD, BALF2, EA/R, VCA p18, VCA p23, gB, gp350, and gp42 were examined in serum pools from SAD patients and healthy controls (HCs). Increased antibody levels against the 11 EBV antigens in the SAD pools were seen compared to the HC pool. Specifically, SLE was characterized by strongly increased IgA to EAD both compared to HCs and other SADs, and RA was characterized by increased IgM levels to several EBV antigens. The SADs may be partly distinguished by their differential immune responses to various antigens in the EBV life cycle. All together, these findings support an association between EBV infection and SADs.
