inmunology and infection

BACKGROUND: HIV/AIDS (Human immunodeficiency virus/Acquired immune deficiency syndrome) not only has a strong impact on the health of the worldwide population but also affects the labour status of HIV-positive people. The primary aim of this paper is to compare the labour participation of people living with HIV (PlwHIV) with the labour participation of the general population along the last business cycle in Spain. METHOD: The data used are from the Hospital Survey on HIV-AIDS, with a total sample size of 4,651 PlwHIV and the Labour Force Survey from 2001 to 2010, with a total sample size of 660,674 individuals as general population...

Antimicrobial resistance in complex models of continuous infection is a current issue. The update 2017 course addresses about microbiological, epidemiological and clinical aspects useful for a current approach to infectious disease. During the last year, nosocomial pneumonia approach guides, recommendations for management of yeast and filamentous fungal infections, review papers on the empirical approach to peritonitis and extensive guidelines on stewardship have been published. HIV infection is being treated before and more intensively...

Hansen's disease presents a wide spectrum of clinical and histopathological manifestations that reflect the nature of the immunological response of the host towards diverse Mycobacterium leprae components. The immunological system, composed by both innate and adaptive immunology, offers protection towards infections of various etiologies, among them bacterial. Bacteria, of course, have developed multiple strategies for evading host defenses, based on either very complex or simple mechanisms, but with a single purpose: to "resist" host attacks and to be able to survive...

Basiliximab induction treatment has been shown to reduce the incidence of acute rejection episodes without the secondary side effects observed with antilymphocyte polyclonal antibodies. We analyzed our experience with basiliximab induction associated with tacrolimus-based immunosuppression among low-immunological risk renal transplant recipients. We retrospectively analyzed 55 renal transplantation patients of low inmunological risk who received organs from donors younger than 55 years. We compared a group of 21 patients (38...

Superficial mycoses are considered to affect more frequently patients with type 2 diabetes mellitus (DM-2), specially onychomycosis and Tinea pedis. The purpose of this study was to compare the dermatophytoses, candidiasis and Pitiriasis versicolor frequency between 40 patients with DM-2 and 40 healthy persons of either sex, 40 years old or more. Clinical, metabolic, mycologic and inmunologic studies against Candida albicans, were carried out. Both diabetics 75% (30/40) and controls 65% (26/40) presented a high frequency of superficial mycoses (no significant difference p = 0...

There is great evidence that both gastric lymphoma andadenocarcinoma are related in their pathogenesis to Helicobacter pylori infection.It has been stablished that mucosa associated lymphoid tissue (MALT) is anacquired condition following H. pylorl infection and that B cell gastriclymphoma derives from this cell linage. Low grade MALT lymphoma transformsto high grade lymphoma. Furthermore, MALT B cell lymphoma seems toproliferate in response to an antigenic stimulus provided by T cell line of cells specificately activated by H...

BACKGROUND: We aimed at determining the inmunological status regarding varicella and parvovirus B19 in pregnant women in Gijón, Spain, and its correlation with several clinical and epidemiological parameters. PATIENTS AND METHOD: Blood samples taken during the first trimester of pregnancy in the area of Gijón were analysed to determine the immunological status with respect to varicella and parvovirus B19. The study included 2 groups: 99 non-European (all tested for both varicella and parvovirus) and 2,188 Europeans (406 were randomly selected for varicella test and 287 for parvovirus test)...

OBJECTIVE: To know the incidence and risk's factors of nosocomial pneumonia (NN) in patient entered in hospital with age more of 14 years-old. The study was not performed in patients of Unit Care. Also, morbility and mortality are showed and the relation between bacterial agent and inmunologic answer of the patients. By other hand, we reported about specific clinical predictors for NN. MATERIALS AND METHODS: During a period of twenty-two months, 103 cases of NN were diagnosed what supposed 0...

This is a report of three cases of mycetome studied in our laboratory during the last four years. We also informed about the evolution of the first case produced by Pyrenochaeta romeroi nova species reported by Borelli in 1959. All the patients were farmer men, 18, 42 and 54 years old, from the semiarid and subhumid zones of Falcon State, located on the northwest region of Venezuela. Clinically, all patients presented the mycetome syndrome (subcutaneous edema, sinus tract and "granules"), with a evolution of six months to three years...

OBJECTIVE: To compare the different diagnostic techniques of Helicobacter Pylori infection, confronting the bacteriological culture to other faster, less expensive and easier techniques, such as the urease test, methylen blue and Gram stained smears, the histopathologic examination of biopsies specimens, and the detection of IgG antibodies anti Helicobacter Pylori. MATERIAL AND METHODS: 43 patients with gastroduodenal symptoms who had not taken NSAIDs and who presented endoscopic signs of inlammation and/or gastroduodenal ulcer were prospectively studied...
