Infection in Humans: A Comprehensive Approach Involving the General Population, HIV-Infected Patients and Intermediate-Duration Fever in the Canary Islands, Spain.

A prior investigation in 1993 identified a high seroprevalence of toxoplasmosis (63%) in the Canary Islands. This study aims to assess the current prevalence of the disease in diverse population groups. The study was based on a population-scale screening involving 273 residents utilizing IgG ELISA and a 20 year retrospective study (1998-2018).

Increased peripartum mortality associated with maternal subclinical malaria in Mozambique.

Background: Plasmodium falciparum infection in pregnant women in sub-Saharan Africa is often asymptomatic. As these forms of malaria are often submicroscopic and difficult to diagnose by conventional methods (microscopy and/or rapid diagnostic test), diagnosis requires the use of molecular techniques such as polymerase chain reaction (PCR). This study analyses the prevalence of subclinical malaria and its association with adverse maternal and neonatal outcomes, a topic that has been scarcely evaluated in the literature.

Seroprevalence of in Patients about to Receive Immunosuppressive Treatment in Gran Canaria (Spain).

infection is generally asymptomatic or mildly symptomatic, but in the immunosuppressed host, it is associated with more severe and complicated forms with a worse prognosis. seroprevalence was studied in 256 patients before receiving immunosuppressive treatment (before kidney transplantation or starting biological treatments). As a control group, serum bank data of 642 individuals representative of the population of the Canary Islands were retrospectively analyzed.

Effects of HIV infection and/or malaria on maternal and neonatal health in a high-prevalence setting.

Objective: HIV infection and malaria have been associated with different complications during pregnancy and delivery. HIV-positive pregnant women are at increased risk for all adverse outcomes of malaria during pregnancy. The main objective was to analyse the obstetric and perinatal consequences of malaria, HIV infection and HIV/malaria co-infection in pregnant women and newborns, which has been less well evaluated.

Monkeypox and HIV in the Canary Islands: A Different Pattern in a Mobile Population.

Background: The clinical and epidemiological data of the recent outbreak of monkeypox (MPX) differ from previous reports. One difference is the epidemiological profile; the disease mainly affects a subgroup of MSM (men who have sex with men) with high-risk sexual behaviors, frequently persons living with human immunodeficiency virus (PLHIV).

Methods: In this observational analysis, all patients with PCR (polymerase chain reaction)-confirmed MPX attending an Infectious Diseases and Tropical Medicine Unit in Gran Canaria (Spain) between May and July 2022 were considered.

Murine typhus. How does it affect us in the 21st century? The epidemiology of inpatients in Spain (1997-2015).

Objective: The aim of this study was to analyze the epidemiological impact of murine typhus in patients who required hospitalization in the National Health System (SNS) in Spain between 1997 and 2015.

Background: Murine typhus (MT) is a zoonosis caused by Rickettsia typhi. MT is transmitted from rats, cats, dogs, and opossums to humans by their fleas.

Epidemiological scenario of Q fever hospitalized patients in the Spanish Health System: What's new.

Objectives: The objective of this study was to assess the epidemiology and burden of Q fever (QF) in Spain.

Methods: We designed a retrospective descriptive study using the minimum basic data set in patients admitted to hospitals of the National Health System between 1998 and 2015 with a diagnosis of Q fever (ICD-9: 083.0.

Detection of Schistosoma mansoni-derived DNA in human urine samples by loop-mediated isothermal amplification (LAMP).

Background: Schistosoma mansoni is the main species causing hepatic and intestinal schistosomiasis in Sub-Saharan Africa, and it is the only species in South America. Adult stages of the parasite reside in the mesenteric venous plexus of infected hosts, and eggs are shed in feces. Collecting patient stool samples for S.

[Epidemiology of Q fever in Spain (2018)].

Q fever is an anthropozoonosis whose causative agent is Coxiella burnetii, which has an important impact from the human and animal health point of view. In this review, a brief historical reference of the infection by C. burnetii and Q fever has been made initially.

Surveillance of strongyloidiasis in Spanish in-patients (1998-2014).

Background: Strongyloides stercoralis is a parasite that causes strongyloidiasis, a neglected tropical disease. S. stercoralis is a soil-transmitted helminth that is widely distributed in tropical and subtropical regions of the world.

[Febrile syndromes in the traveler returning from tropical regions admitted in a monographic unit].

Objective: The aim was to analyse those syndromes with fever in travellers who return from tropical regions evaluated at our Department of Infectology and Tropical Medicine. Clarifying these conditions intends to reach earlier diagnoses and, perhaps, to avoid the emergence and spread of imported diseases, as well as to establish appropriate preventive measures.

Methods: An observational descriptive transversal study was performed, selecting those patients who returned from tropical regions with fever, amongst all travellers evaluated in our department between 1998 and 2013.

Immune Reconstitution Inflammatory Syndrome in HIV-Infected Immigrants.

Immune reconstitution inflammatory syndrome (IRIS) includes a group of potentially serious inflammatory processes that may be present in HIV-infected patients after initiating highly active antiretroviral therapy (HAART). is a worsening of symptoms, after an overwhelming response to a previously diagnosed opportunistic infection (OI); reveals a previously occult OI. The main objective of the study was to describe the epidemiological, clinical, and outcome data of HIV-infected immigrants, stratified according to high- or low-income countries of origin, who developed IRIS and to compare them with native-born Spanish patients.

Detection of Coxiella burnetii DNA in Peridomestic and Wild Animals and Ticks in an Endemic Region (Canary Islands, Spain).

Coxiella burnetii, the etiological agent of human Q fever, can infect mammals, birds, and arthropods. The Canary Islands (Spain) are considered an endemic territory, with a high prevalence in both humans and livestock. Nonetheless, there is no epidemiological information about the wild and peridomestic cycles of C.

Executive summary of imported infectious diseases after returning from foreign travel: Consensus document of the Spanish Society for Infectious Diseases and Clinical Microbiology (SEIMC).

In a global world, knowledge of imported infectious diseases is essential in daily practice, both for the microbiologist-parasitologist and the clinician who diagnoses and treats infectious diseases in returned travelers. Tropical and subtropical countries where there is a greater risk of contracting an infectious disease are among the most frequently visited tourist destinations. The SEIMC considers it appropriate to produce a consensus document that will be useful to primary care physicians as well as specialists in internal medicine, infectious diseases and tropical medicine who help treat travelers returning from tropical and sub-tropical areas with infections.

Endomyocardial involvement in asymptomatic sub-Saharan immigrants with helminth-related eosinophilia.

Background: Among immigrants of sub-Saharan origin, parasitic infection is the leading cause of eosinophilia, which is generally interpreted as a defense mechanism. A side effect of the inflammatory mediators released by eosinophils is damage to host organs, especially the heart. The main objectives of this study were to i) assess cardiac involvement in asymptomatic sub-Saharan immigrants with eosinophilia, ii) relate the presence of lesions with the degree of eosinophilia, and iii) study the relationship between cardiac involvement and the type of causative parasite.

[Non-febrile syndromes in the traveler returning from tropical regions admitted in a monographic unit].

Objective: The aim was to analyse those syndromes without fever in travellers who return from tropical regions evaluated at our Department of Infectology and Tropical Medicine. Clarifying these conditions intends to reach earlier diagnoses and, perhaps, to avoid the emergence and spread of imported diseases, as well as to establish appropriate preventive measures.

Methods: An observational descriptive transversal study was performed, selecting those patients who returned from tropical regions without fever (n = 281), amongst all travellers evaluated in our department between 1998 and 2013.

[Diagnosis and treatment of imported eosinophilia in travellers and immigrants: Recommendations of the Spanish Society of Tropical Medicine and International Health (SEMTSI)].

According to published data, prevalence of imported eosinophilia among travellers and immigrants is set between 8% and 28.5%. Etiological diagnosis is often troublesome, and depending on the depth of the study and on the population analyzed, a parasitic cause is identified in 17% to 75.
