  • Linkage of G8 (D4S10) in two Swedish families with Huntington's disease.

    • Two Swedish families with Huntington's disease (HD) have been investigated for linkage with G8 (D4S10). In one family from northern Sweden (Family 1) 48 family members were examined, and in another family from the southwestern part of Sweden (Family 2) 14 family members were examined. The lod scores were 1.531 for Family 1 and 2.057 for Family 2, and the combined lod score was 3.59. The HD gene was segregating with the haplotype C in Family 1 and with haplotype A in Family 2. The predictive value of the test was obvious. Before the testing with the G8 probe, 84.2% of the family members in Family 1 had a theoretical risk of 25% or 50% of having the HD gene. After the testing with the G8 probe, only 23.7% of the family members remained at the same risk, and it could also be certified that 63.2% had no or little risk of having the HD gene. Only one asymptomatic person was predicted to have HD.

  • Enterotoxigenic Escherichia coli diarrhea in an endemic area prepares the intestine for an anamnestic immunoglobulin A antitoxin response to oral cholera B subunit vaccination.
  • 1988
  • Ingår i: Infection and Immunity. - 0019-9567 .- 1098-5522. ; 56:1, s. 230-3
  • Tidskriftsartikel (refereegranskat)abstract
    • We examined whether infection with enterotoxigenic Escherichia coli (ETEC) producing the heat-labile enterotoxin (LT) can prime the gut immune system to respond more efficiently to the immunologically related cholera B subunit component of a recently developed oral B subunit-whole-cell cholera vaccine (B-WCV). Nine Bangladeshi adults who had been hospitalized for watery diarrhea caused by LT-producing ETEC were given a single oral immunization with B-WCV on day 28 after hospital admission. The vaccine preparation used was adjusted to contain a lower-than-usual dose of B subunit, which had been found in previous studies to elicit a significant gut mucosal immunoglobulin A antitoxin response mainly in individuals with previous toxin-specific priming of their gut immune system. For comparison, nine patients convalescing from severe cholera disease and eight healthy subjects with no recent history of either cholera or ETEC infection were given the same oral vaccination with B-WCV. Vaccination in the ETEC convalescents induced an immunoglobulin A antitoxin response in intestinal lavage fluid which was comparable with that in the vaccinated cholera convalescents and superior to that in the vaccinated, previously uninfected controls. By contrast, only the cholera patients responded with anamnestic-type anti-cholera lipopolysaccharide antibody titer rises in the intestine after vaccination. These data support the specificity of the anamnestic anti-cholera toxin response in the ETEC patients after vaccination with cholera B-WCV.

  • Local and systemic antibody responses to naturally acquired enterotoxigenic Escherichia coli diarrhea in an endemic area.
  • 1986
  • Ingår i: Journal of Infectious Diseases. - 0022-1899 .- 1537-6613. ; 153:3, s. 527-34
  • Tidskriftsartikel (refereegranskat)abstract
    • Fifteen patients hospitalized with acute, watery diarrhea and with enterotoxigenic Escherichia coli (ETEC) detected from stool samples were studied to evaluate the extent to which natural ETEC diarrhea induces local and systemic antibody responses to E. coli heat-labile toxin (LT), homologous lipopolysaccharide (LPS), and colonization factors (CFA/I and CFA/II). Specific IgA and IgG antibodies to LT, CFA I and II, and each patient's homologous LPS were determined by ELISA in serum, saliva, breastmilk, and intestinal lavage fluid. The majority of patients had greater than a twofold rise in local levels of IgA antibodies in the intestine: 80% of LT+ patients responded to LT, 63% of CFA+ patients responded to CFA, and 78% of all toxin-positive patients responded to the LPS of their infecting strain. Local antibody responses in the intestine were associated with responses in breastmilk and saliva, but relationships were not clear-cut, and the usefulness of these secretions as proxy measures of local intestinal antibody production remains unclear. Antibody responses in serum also occurred in most patients and were significantly more frequent in cases than in controls. This study demonstrates that natural ETEC disease results in local IgA responses to LT, CFA, and LPS in the gut and also in immune responses in breastmilk, saliva, and serum.
