Ileus bei ausgedehnten intraabdominellen Verkalkungen nach Peritonitis

Zusammenfassung. Wir berichten über einen 48 j?hrigen Patienten. In Folge einer bakteriellen Peritonitis hatten sich ausgedehnte intraabdominelle Verkalkungen gebildet. Diese hatten einen Obstruktionsileus verursacht. Im Rahmen einer Revisionslaparotomie wurden die Kalkspangen entfernt. Zur Rezidivprophylaxe veranla?ten wir eine percutane Bestrahlung mit 15 Gy. Zus?tzlich erfolgte eine systemische Indometacin-Applikation. Eine Literaturrecherche ergab nur 2 vergleichbare F?lle.      

Die Insuffizienz der intraabdominellen Infektabwehr bei der eitrigen Peritonitis — Folge einer gestörten Fremdkörperopsonierung

Summary Despite a high concentration of serum proteins and intact phagocytes peritonitis exudates contain a large number of viable, pathogenic bacteria. The reason for this biological paradox is unknown. Our investigations reveal a pronounced defect in humoral opsonization of foreign particles in peritonitis exudate. We evaluated a modified chemiluminescence system allowing the determination of opsonic activity in serum and exudate. In serum we found a close correlation between opsonic activity and immunologically measurable levels of C₃-complement and IgG. In purulent peritonitis exudates, however, the actual opsonizing activity was much less than expected according to the opsonin concentrations. We found a pronounced difference between immunologically determined opsonin levels and impaired opsonic function. Employing crossed immunoelectrophoresis massive C₃-splitting into smaller fragments could be demonstrated in peritonitis exudates. In these exudates we found very high concentrations of granulocyte proteolytic (elastase) and oxidative (myeloperoxidase) enzymes which may lead to a functional destruction of opsonins followed by impaired opsonization in peritonitis exudate. The great number of bacteria and foreign particles in addition can cause a pronounced physiological consumption of complement components. The almost complete breakdown of intact C₃-complement in intraabdominal exudate explains the deficient host defence in patients with severe peritonitis.

Sequence Analysis of the RNA Polymerase Gene of Foot-and-Mouth Disease Virus Serotype Asia1

The complete nucleotide (nt.) sequence of the RNA polymerase (3D) gene and 81 nt. in the 3-untranslated region of foot-and-mouth disease virus (FMDV) serotype Asia1 (IND63/72) was determined and compared with the sequence of other FMDV serotypes. The 3D genomic region was 1410 nt. long encoding 470 amino acids with an inframe stop codon (TAA) at nt. position 1411–1413. The deduced amino acid sequence of the protein showed 8 conserved motifs as reported in other picornaviruses, 2 of which are 100% identical across the serotypes. Antigenic regions in the polymerase protein were predicted and found to be located at the N-terminus of the protein. The phylogenetic analysis showed that the FMD viruses were segregated into different clusters based on geographical origin; the Asia1 virus did not cluster tightly with any of the geographical groups.
