OBJECTIVE Our aim was to study the proportion of healthcare workers with a positive serology for Influenza A(H1N1)2009 without having flu, in a Spanish hospital at the beginning of the pandemic. METHODS A survey study carried out during August 2009 (before the peak of the pandemic in Spain) in the Hospital Costa del Sol, a second level hospital with almost 300 beds in the South of Spain. The ...

Background and Objective: Opportunistic infections are the leading cause of death among patients subjected to the human immunodeficiency virus (HIV) infection and acquired immune deficiency syndrome (AIDS). The aim of this study was to compare the seroprevalence of Cytomegalovirus (CMV)  and toxoplasmosis infection in newly diagnosed HIV infected patients with healthy controls and it’s correlat...

AIMS To determine whether the polymerase chain reaction with sequence specific primers (PCR-SSP) can assign HLA-DR type more accurately than serology in a routine hospital laboratory. METHODS The 93 patients currently awaiting kidney transplants have been DR typed by serology over the past 14 years, 82% within the past five years. They have now been retyped using the PCR-SSP method described ...

CONTEXT Multiple diagnostic methods are available for the detection of Helicobacter pylori infection, but at present no single one can be used as the gold standard. OBJECTIVE The aim of this study was to evaluate the diagnostic accuracy of 3 invasive and 2 non-invasive methods for detection of Helicobacter pylori infection in symptomatic children and adolescents. DESIGN Prospective cohort s...

The cut-off values used in C6 peptide-based enzyme immunoassay (EIA), a widely test Lyme borreliosis (LB) serology, have not been thoroughly analysed. objective of the study was to examine performance EIA, and determine optimal for test. analysed data contained results 1368 serum samples. EIA index were compared statistically with immunoblot (IB) results. identified further tested well-defined ...

We investigated the prevalence of positive viral hepatitis titres in sickle cell disease (SCD) and the relationship of abnormal liver function tests (LFTs) to transfusions and ferritin levels. Charts from 141 patients with SCD were reviewed and recent laboratory data on serum ferritin, hepatitis serology, units of packed red blood cells transfused and LFTs were collected. Hepatitis B core antib...

OBJECTIVE To measure the serum levels of brain natriuretic peptide (BNP) in patients with chronic chagasic heart disease and in individuals with positive serology for Chagas' disease and no heart impairment, and to correlate the serum BNP levels with the degree of cardiac impairment, cardiac dimensions, presence of a pacemaker, and ejection fraction. METHODS Serum BNP concentrations were dete...

serology and dna techniques are employed for human leukocyte antigen (hla) typing in different transplant centers. results may not always correlate well and may need retyping with different technique. all the patients (with aplastic anemia, thalassemia, and immunodeficiency) and their donors, requiring hla typing for bone marrow transplant were enrolled in the study. serological hla typing was ...
