Normal serum levels of immune complexes in postpolio patients.

Results in immunology

Melin E, Sohrabian A, Rönnelid J, Borg K.
PMID: 25009767
Results Immunol. 2014 Jun 18;4:54-7. doi: 10.1016/j.rinim.2014.06.001. eCollection 2014.

OBJECTIVE: The pathophysiology of the postpolio syndrome is not fully understood. Increased cytokine levels in cerebrospinal fluid and peripheral blood indicate a systemic inflammatory process. Decreased cytokine levels and the clinical effect of intravenous immunoglobulin treatment further indicate an...

PMID: 26284075
Front Immunol. 2015 Aug 03;6:392. doi: 10.3389/fimmu.2015.00392. eCollection 2015.

During the last 25 years, clinical autoantibody determinations have changed dramatically. Old and slow techniques with high diagnostic specificity have been replaced with automated and faster techniques that most often have a higher diagnostic sensitivity at the expense of...

Extramucosal formation and prognostic value of secretory antibodies in rheumatoid arthritis.

Arthritis & rheumatology (Hoboken, N.J.)

Martinsson K, Lyttbacka Kling L, Roos Ljungberg K, Griazeva I, Samoylovich M, Paul S, Rönnelid J, Weitoft T, Wetterö J, Kastbom A.
PMID: 34927393
Arthritis Rheumatol. 2021 Dec 20; doi: 10.1002/art.42044. Epub 2021 Dec 20.

OBJECTIVE: To investigate levels and possible extramucosal formation of secretory immunoglobulins, including anti-citrullinated protein antibodies (ACPA), in rheumatoid arthritis (RA).METHODS: Three patient groups were studied: i) ACPA-positive patients with musculoskeletal pain without clinical arthritis, ii) recent-onset RA, and iii)...

Functional and Structural Characterization of a Novel HLA-DRB1*04:01-Restricted α-Enolase T Cell Epitope in Rheumatoid Arthritis.

Frontiers in immunology

Gerstner C, Dubnovitsky A, Sandin C, Kozhukh G, Uchtenhagen H, James EA, Rönnelid J, Ytterberg AJ, Pieper J, Reed E, Tandre K, Rieck M, Zubarev RA, Rönnblom L, Sandalova T, Buckner JH, Achour A, Malmström V.

Front Immunol. 2016 Nov 14;7:494. doi: 10.3389/fimmu.2016.00494. eCollection 2016.

Antibodies to citrullinated proteins, common in rheumatoid arthritis (RA) patients, are strongly associated to a specific set of HLA-DR alleles including HLA-DRB1*04:01, *04:04, and *01:01. Here, we first demonstrate that autoantibody levels toward the dominant citrullinated B cell epitope...

Associations with thrombosis are stronger for antiphosphatidylserine/prothrombin antibodies than for the Sydney criteria antiphospholipid antibody tests in SLE.

Lupus

Elbagir S, Grosso G, Mohammed NA, Elshafie AI, Elagib EM, Zickert A, Manivel VA, Pertsinidou E, Nur MAM, Gunnarsson I, Rönnelid J, Svenungsson E.
PMID: 33957795
Lupus. 2021 Jul;30(8):1289-1299. doi: 10.1177/09612033211014570. Epub 2021 May 06.

OBJECTIVES: Antiphosphatidylserine/prothrombin complex antibodies (aPS/PT) are risk factors for thrombosis, yet further validation of their clinical relevance in different ethnic groups is required. We investigated the performance of aPS/PT of IgA/G/M isotypes among Sudanese and Swedish systemic lupus erythematosus...

Auto Immun Highlights. 2020 Sep 03;11(1):12. doi: 10.1186/s13317-020-00134-0.

Special conditions associated with laboratory autoimmune testing are not well compatible with recent developments in regulatory frameworks such as EN/ISO 15189 accreditation or in vitro diagnostic medical device regulation (IVD-R). In addition, international recommendations, guidelines and disease criteria are...

Impact of autoimmune serology test results on RA classification and diagnosis.

Journal of translational autoimmunity

Rheumatoid arthritis (RA) is the most common systemic autoimmune disease and also the most severe arthritic disorder. The measurement of rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) in serum supports the diagnosis of RA, which gained increasing significance...

Optical acceptance function of modified compound parabolic concentrators with linear corrugated reflectors.

Applied optics

Rönnelid M, Karlsson B.
PMID: 18286000
Appl Opt. 1998 Aug 01;37(22):5222-6. doi: 10.1364/ao.37.005222.

For reflective cylindrical concentrators the acceptance function, as determined in the meridian plane, remains constant for more oblique planes of incidence. However, if the reflective surface has a linear corrugated structure, it is possible to increase the acceptance in...

Optical scattering from rough-rolled aluminum surfaces.

Applied optics

Rönnelid M, Adsten M, Lindström T, Nostell P, Wäckelgård E.
PMID: 18357222
Appl Opt. 2001 May 01;40(13):2148-58. doi: 10.1364/ao.40.002148.

Bidirectional, angular resolved scatterometry was used to evaluate the feasibility of using rolled aluminum as reflectors in solar thermal collectors and solar cells. Two types of rolled aluminum with different surface roughnesses were investigated. The results show that the...
