Reports (pop. science, debate, etc.)abstract
- Denna skrift utgör resultatet av Arkitekturskolans studier läsåret 1978-79. Att redigera manuskripten visade sig arbetskrävande och har också dragit ut på tiden. Att vissa av de uppgifter som lämnas inte är helt aktuella spelar ändå inte så stor roll - tyngdpunkten i framställningen ligger på det historiska materialet och de långa tidsperspektiven.Arbetet inleds med en demografisk översikt över ett brett bälte tvärs över Mellansverige från Värmland till Upplandskusten. Där antyds utvecklingens huvudriktning både i Bergslagens gamla kärnområden och i yttre zoner av delvis annan karaktär. Därefter följer åtta från varandra fristående kapitel som dock alla har ett gemensamt mål, att granska och analysera bebyggelseu.tvecklingen inom ett tydligt avgränsat område. Konkretion och åskådlighet har eftersträvats - därför har också stor möda nedlagts på bildmaterialet i form av kartor, ritningar och foton. Valet av undersökningsobjekt har gjorts av författarna själva, som också utformat sina avsnitt självständigt.

Immunoglobulin deficiencies and susceptibility to infection among homozygotes and heterozygotes for C2 deficiency
- 2003
-
In: Journal of Clinical Immunology. - 0271-9142. ; 23:4, s. 297-305
-
Journal article (peer-reviewed)abstract
- About 25% of C2-deficient homozygotes have increased susceptibility to severe bacterial infections. C2-deficient homozygotes had significantly lower serum levels of IgG2, IgG4, IgD, and Factor B, significantly higher levels of IgA and IgG3 and levels of IgG1 and IgM similar to controls. Type I ( 28 bp deletion in C2 exon 6 on the [HLA-B18, S042, DR2] haplotype or its fragments) and type II ( non-type I) C2-deficient patients with increased susceptibility to bacterial infection had significantly lower mean levels of IgG4 ( p < 0.04) and IgA ( p < 0.01) than those without infections ( who had a higher than normal mean IgA level) but similar mean levels of other immunoglobulins and Factor B. Of 13 C2-deficient homozygotes with infections, 85% had IgG4 deficiency, compared with 64% of 25 without infections. IgD deficiency was equally extraordinarily common among infection-prone (50%) and noninfection-prone (70%) homozygous type I C2-deficient patients. IgD deficiency was also common (35%) among 31 type I C2-deficient heterozygotes ( with normal or type II haplotypes), but was not found in 5 type II C2-deficient heterozygotes or 1 homozygote. Thus, C2 deficiency itself is associated with many abnormalities in serum immunoglobulin levels, some of which, such as in IgG4 and IgA, may contribute to increased susceptibility to infection. In contrast, IgD deficiency appears not to contribute to increased infections and appears to be a dominant trait determined by a gene or genes on the extended major histocompatibility complex (MHC) haplotype [HLA-B18, S042, DR2] ( but probably not on type II C2-deficient haplotypes) similar to those previously identified on [HLA-B8, SC01, DR3] and [HLA-B18, F1C30, DR3].

Journal article (peer-reviewed)abstract
- Objective. To compare antibody responses to 23-valent pneumococcal vaccine (Pneumovax (R)) in controls and patients with established rheumatoid arthritis (RA) treated with TNF blockers, methotrexate (MTX) or a combination of both. Methods. Patients with RA (n = 149) and healthy controls (n = 47) were vaccinated. Treatment with TNF blockers (etanercept or infliximab) and MTX was given to 50 patients, and 62 patients were treated with TNF blockers alone or with other DMARDs. MTX alone was given to 37 patients. Concentrations of immunoglobulin G (IgG) antibodies against pneumococcal capsular polysaccharides 23F and 6B were measured by enzyme-linked immunoassay before and 4-6 weeks after vaccination. An immune response was defined as a twofold or higher increase in antibody concentration following vaccination. Results. Prevaccination antibody levels for both 23F and 6B were similar in the patient groups. Antibody concentrations after vaccination increased significantly in all groups. Patients treated with TNF blockers without MTX showed better immune responses than those treated with TNF blockers in combination with MTX (P = 0.037 for 23F and P = 0.004 for 6B) or MTX alone (P < 0.001 for both 23F and 6B). RA patients given MTX alone had the lowest immune responses. Prednisolone treatment did not influence the responses. Conclusions. Patients treated with TNF blockers and controls showed similar responses to vaccination. In contrast, patients treated with MTX had reduced responses regardless of anti-TNF treatment. The findings do not argue against the use of pneumococcal vaccination in RA patients undergoing treatment with TNF blockers.

Complement factor I deficiency associated with recurrent infections, vasculitis and immune complex glomerulonephritis
- 2005
-
In: Scandinavian Journal of Infectious Diseases. - : Informa UK Limited. - 1651-1980 .- 0036-5548. ; 37:8, s. 615-618
-
Journal article (peer-reviewed)abstract
- Here we report complement factor I deficiency in an 11-y-old girl from a consanguineous Turkish family, who presented with recurrent pyogenic infections, vasculitic eruptions and immune complex glomerulonephritis. A moderately low C3 level together with the clinical picture suggested a deficiency affecting regulation of complement activation. Analysis of haemolytic activity revealed absence of alternative pathway activity and subsequent analysis showed no detectable factor I (<2%) together with a low level of factor B and a moderately low level of factor H, indicating consumption secondary to the factor I deficiency. Factor I inhibits complement activation beyond C3 by cleavage of C3b in the presence of cofactors. Complement factor I deficiency is frequently associated with recurrent pyogenic infections mainly affecting the upper and lower respiratory tract, or presenting as meningitis or septicaemia, while rheumatic disorders have not been a prominent feature. The patient's sister also suffered from recurrent pyogenic infections and had a low C3 level clearly suggesting the same deficiency.

Properdin deficiency in a boy with fulminant meningococcal septic shock
- 2006
-
In: Acta Pædiatrica. - : Wiley. - 1651-2227 .- 0803-5253. ; 95:11, s. 1498-1500

Journal article (peer-reviewed)abstract
- Bacterial meningitis is a rare presentation for congenital immunodeficiency, but meningococcal invasive diseases and meningitis have been associated with late complement component deficiencies and properdin deficiency. A 5(1)/(2)-y-old boy of non-consanguineous parents was admitted to our hospital with meningococcal septic shock. He had previously been suffering from recurrent respiratory infections. His 13-y-old brother had also been treated for meningococcal meningitis when he was 7 y old. Immunological studies, done after recovery, on the patient and his two brothers revealed normal immunoglobulin, IgG subclasses, C3, C4 and CH50 levels. Haemolytic activity of the alternative complement pathway could not be detected, and properdin concentrations were < 0.01 mg/l in serum samples from the patient and his brothers. The patient and family members received quadrivalent polysaccharide meningococcal vaccine. The patient was discharged on penicillin prophylaxis, and he remained healthy during the ensuing year. Conclusion: Our findings stress that measurement of the haemolytic activity of the alternative complement pathway in addition to classical pathway haemolytic complement activity should be performed in patients with meningococcal disease to reveal various forms of complement deficiency. This is particularly important when there is a family history, or recurrences or infection due to uncommon serogroups. Deficient individuals and affected family members might be protected from infection by vaccination.

Design of recombinant antibody microarrays for serum protein profiling: Targeting of complement proteins
- 2007

Journal article (peer-reviewed)abstract
- Antibody-based microarrays is a novel technology with great promise for high-throughput proteomics. The process of designing high-performing arrays has, however, turned out to be challenging. Here, we have designed the next generation of a human recombinant scFv antibody microarray platform for protein expression profiling of nonfractionated biotinylated human plasma and serum proteomes. The setup, based on black polymer Maxisorb slides interfaced with a fluorescent-based read-out system, was found to provide specific, sensitive (subpicomolar (pM) range) and reproducible means for protein profiling. Further, a chip-to-chip normalization protocol critical for comparing data generated on different chips was devised. Finally, the microarray data were found to correlate well with clinical laboratory data obtained using conventional methods, as demonstrated for a set of medium abundant (micromolar (mu M) to nanomolar (nM) range) protein analytes in serum and plasma samples derived from healthy and complement-deficient individuals.

Homozygosity for the IgG2 subclass allotype G2M(n) protects against severe infection in hereditary C2 deficiency
- 2006
-
In: Journal of Immunology. - 1550-6606. ; 177:1, s. 722-728
-
Journal article (peer-reviewed)abstract
- Homozygous C2 deficiency (C2D) is the most common deficiency of the classical complement pathway in Western countries. It is mostly found in patients with autoimmune disease or susceptibility to bacterial infections and in healthy persons. We wished to assess to what extent other immunological factors might explain differences of susceptibility to infections in C2D. For this reason, 44 Swedish patients with C2D were stratified with regard to the severity of documented infections. Investigations of IgG subclass levels, IgG subclass-specific GM allotypes, concentrations of factor B, properdin, and factor H, and polymorphisms of mannan-binding lectin and the Fe receptors Fc gamma RIIa and Fc gamma RIIIb were performed. Homozygosity for the G2M*n allele, which is known to promote Ab responses to polysaccharide Ags, was strongly associated with the absence of severe infections (P < 0.001) in the patients, suggesting a major protective role. The combination of mannan (or mannose)-binding lectin and C2 deficiency was found to be a minor susceptibility factor for invasive infection (p = 0.03). Low concentrations of IgG2 and factor B might sometimes contribute to susceptibility to infection. Other factors investigated did not appear to be important. In conclusion, the findings indicated that efficient Ab responses to polysaccharides are protective against severe infection in C2D. Implications with regard to vaccinations should be considered.
