Trends in hospitalizations and deaths in HIV-infected patients in Spain over two decades.

2021

Background The prognosis of HIV infection dramatically improved after the introduction of triple antiretroviral therapy 25 years ago. Herein, we report the impact of further improvements in HIV management since then, looking at all hospitalizations in persons living with HIV (PLWH) in Spain. Methods Retrospective study using the Spanish National Registry of Hospital Discharges. Information was retrieved since 1997 to 2018. Results From 79,647,783 nationwide hospital admissions recorded during the study period, 532,668 (0.67%) included HIV as diagnosis. The mean age of PLWH hospitalized increased from 33 to 51 years-old (p < 0.001). The rate of HIV hospitalizations significantly declined aft…

Cervical ectopy: associations with sexually transmitted infections and HIV. A cross-sectional study of high school students in rural South Africa.

2014

Objectives It has been hypothesised that ectopy may be associated with increased susceptibility to sexually transmitted infections (STIs). In this cross-sectional study, we wanted to explore the association between STIs (including HIV) and cervical ectopy. Methods We included 700 sexually active young women attending randomly selected high schools in a rural district in KwaZulu-Natal, South Africa. The district is endemic of HIV and has a high prevalence of STIs. We did computer-assisted measurements of the ectocervical area covered by columnar epithelium (ectopy) in colposcopic images and STI analyses on cervicovaginal lavage and serum samples. All participating women answered a questionna…

Pregnancy outcomes in women with advanced HIV infection in Italy

2011

Pregnancy has been associated with a low risk of HIV disease progression. Most pregnancies with HIV currently involve women who have not experienced AIDS-defining events, and are clinically classified as Centers for Disease Control and Prevention (CDC) groups A or B. We evaluated the main maternal outcomes among pregnant women with more advanced HIV disease, defined by CDC-C disease stage. Data from the Italian National Program on Surveillance on Antiretroviral Treatment in Pregnancy were used. A total of 566 HIV-infected mothers, 515 in stage A or B (CDC-AB group) and 51 in stage C (CDC-C group) were evaluated. The two groups had similar baseline characteristics. No differences were found …

The labyrinth of autoinflammatory disorders: a snapshot on the activity of a third-level center in Italy.

2015

Autoinflammatory disorders (AIDs) are a novel class of diseases elicited by mutations in genes regulating the homeostasis of innate immune complexes, named inflammasomes, which lead to uncontrolled oversecretion of the proinflammatory cytokine interleukin-1β. Protean inflammatory symptoms are variably associated with periodic fever, depicting multiple specific conditions. Childhood is usually the lifetime in which most hereditary AIDs start, though still a relevant number of patients may experience a delayed disease onset and receive a definite diagnosis during adulthood. As a major referral laboratory for patients with recurrent fevers, we have tested samples from 787 patients in the perio…

Does the association of therapeutic exercise and supplementation with sucrosomial magnesium improve posture and balance and prevent the risk of new f…

2021

Abstract Background Fracture of the proximal femur is the most feared complication of osteoporosis. Given the numerous physiological functions that magnesium performs in our body, in the literature there is a correlation between osteoporosis and low serum levels of magnesium. Aim Evaluate the incidence of hypomagnesemia in patients with lateral fragility fracture of the proximal femur, the possible correlation between serum magnesium levels and fractures, and the effectiveness of supplementing Sucrosomial® magnesium associated with therapeutic exercise on the outcome of these patients. Methods We divided the study into two parts. In the first part, we assessed the preoperative incidence of …

Polyclonal antibodies to mannan from yeast also recognize the carbohydrate structure of gp120 of the AIDS virus: an approach to raise neutralizing an…

1990

This study initiates a new method of developing an antigen which might be useful in the prevention of HIV-1 infection. Using a mannan preparation from Saccharomyces cerevisiae neutralizing antiserum was raised in rabbits which prevents HIV-1 infection in vitro up to a titre of 1:128. The corresponding antibody preparation neutralized the in vitro infectivity down to a concentration of 5 micrograms/ml. Analytical studies suggest that the antibodies are directed against the mannose residues of the HIV-1 glycoprotein (gp) 120 and its precursor gp 160.

The role of post-transcriptional modulators of metalloproteins in response to metal deficiencies

2021

Copper and iron proteins play a wide range of functions in living organisms. Metal assembly into metalloproteins is a complex process, where mismetalation is detrimental and energy-consuming to cells. Under metal deficiency, metal distribution is expected to reach a metalation ranking, prioritizing essential versus dispensable metalloproteins, while avoiding interferences with other metals and protecting metal-sensitive processes. In this review, we propose that posttranscriptional Modulators of Metalloprotein messenger RNA (ModMeR) are good candidates in metal prioritization under metal-limited conditions. ModMeR target high quota or redundant metalloproteins and, by adjusting their synthe…

Scientific HIV research in Africa and the Middle East: a socio-economic demographic analysis

2021

Background: In Africa, HIV/AIDS research is concentrated in certain countries, particularly South Africa. This distribution may not accurately reflect the disease prevalence or the true research efforts of countries.Objectives: To identify HIV/AIDS research productivity of countries in Africa and the Middle East, in absolute terms and adjusted for people living with HIV, population size and economic development.Methods: We identified all the articles and reviews on HIV and AIDS in the Web of Science Core Collection in which African or Middle Eastern countries had participated. After determining the number of documents produced by each country, we adjusted the findings for the number of peop…

Inhibition of human immunodeficiency virus-1 infection by human conglutinin-like protein: in vitro studies.

1992

The lectin-like protein analogous to bovine conglutinin was purified from human serum. The carbohydrate-binding ability of conglutinin-like protein was inhibited by D-mannose, N-acetylglucosamine and L-fucose as well as by mannan-containing oligosaccharides. By applying a lectin-based ELISA system it was demonstrated that conglutinin-like protein binds to human immunodeficiency virus-1 (HIV-1) glycoprotein 120 (gp120) via its carbohydrate binding site. In vitro experiments with T-lymphoblastoid CEM cells revealed that conglutinin-like protein abolishes infection by HIV-1; a 50% cytoprotective concentration of 23.9 micrograms/ml was measured. These findings demonstrate that human conglutinin…
