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 in Canary Islands, Spain, 1999-2015.

To document the epidemiology, clinical features, and outcomes of murine typhus patients in the Canary Islands (Spain), we analyzed data that were retrospectively collected for 16 years for 221 patients. Murine typhus in the Canary Islands is characterized by a high rate of complications (31.6%), mainly liver, lung, kidney or central nervous system involvement.

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.

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.

Usefulness of the early molecular diagnosis of Q fever and rickettsial diseases in patients with fever of intermediate duration.

Most cases of fever of intermediate duration (FDI) in Spain are associated with infectious diseases (mainly Q fever and rickettsia infections). In clinical practice, the causal diagnosis of these entities is based on immunodiagnostic techniques, which are of little help in the early stages. Therefore, the aim of this study was to evaluate the usefulness of molecular techniques for the early diagnosis of Q fever and rickettsia diseases in patients with FDI.

Compartmental syndrome of the upper limb due to Moraxella lacunata infection: a link to patera foot syndrome?

We report a case of compartmental syndrome of the left upper limb secondary to a severe Moraxella lacunata infection, an unusual pathogen, occurring in a young black male immigrant to the island of Gran Canaria, Spain. We propose a pathophysiological relationship with patera foot syndrome.

Skin and soft tissue infections (patera foot) in immigrants, Spain.

An unusual skin and soft tissue infection of the lower limbs has been observed in immigrants from sub-Saharan Africa who cross the Atlantic Ocean crowded on small fishing boats (pateras). Response to conventional treatment is usually poor. Extreme extrinsic factors (including new pathogens) may contribute to the etiology of the infection and its pathogenesis.

Helicobacter pylori and cagA seroprevalence in sub-Saharan inmigrants recently arrived to Gran Canaria (Spain).

Non-ulcerous dyspepsia is common among sub-Saharan people migrating into Spain. Given the high prevalence of H. pylori (HP) infection in their countries of origin, we studied the prevalence of infection in this population, and specifically the prevalence of infection by the more virulent, cagA-positive strains (CAP).

[Automated erythrocytapheresis as treatment of severe malaria. Study of 6 patients].

Background And Objective: The high mortality attributable to severe malaria by Plasmodium falciparum is related to the grade of parasitemia. Automated erithrocytapheresis (AE) is a safe alternative to exchange transfussion, with the same potential benefits but less undesirable side effects. Literature on this technique is scarce, consisting of isolated reports or short series.
