Novel serum inflammatory markers in acute appendicitis.

Background: Cytokines and leukocyte adhesion molecules are activated and found in increased concentrations in bacterial infection. The purpose of this study was to investigate whether some of these new serum markers could be feasible as a single on-admission test to predict acute appendicitis (AA).

Methods: In an open prospective study the diagnostic potentials of two cytokine measurements (interleukin-6 and interleukin-8), soluble leukocyte adhesion molecule (CD44), C-reactive protein (CRP) and white blood cell (WBC) count were compared in 80 consecutive patients who had undergone surgery for suspected AA.

The evolutionarily conserved avian Aiolos gene encodes alternative isoforms.

Aiolos is an Ikaros-related lymphoid regulatory protein involved in B cell development and function. To evaluate the role of Aiolos in avian B lymphopoiesis, we have cloned and characterized the first non-mammalian Aiolos ortholog in the avian. In sharp contrast to the avian Ikaros, expressed already at the multipotential stage and prior to the colonization of the lymphoid rudiments, Aiolos transcripts were not expressed in early ontogeny and were first detected in cells isolated from the embryonic bursa of Fabricius and thymus.

Are serum inflammatory markers age dependent in acute appendicitis?

Background: Preoperative measurement of body inflammatory agents reduces unnecessary appendectomies by up to 30 percent. A decline in the formation of blood leukocytes and C-reactive protein with aging may hinder the correct diagnosis of appendicitis.

Study Design: White cell count and C-reactive protein were determined before appendectomy in 600 patients aged 0 to 5 years, 6 to 19 years, 20 to 39 years, 40 to 59 years, 60 to 79 years, and older than 80 years.

Diagnosis of Helicobacter pylori infection by using pyloriset EIA-G and EIA-A for detection of serum immunoglobulin G (IgG) and IgA antibodies.

We evaluated the performance of new enzyme immunoassay (EIA) kits (Pyloriset; Orion Corporation, Orion Diagnostica, Espoo, Finland) for the detection of immunoglobulin G (IgG) and IgA antibodies to Helicobacter pylori in serum. Serum samples from 195 patients with upper abdominal complaints were collected. Biopsy specimens of the gastric mucosae were taken for histological analysis and bacterial culture.
