HIV-positive Ukrainian refugees in the Czech Republic.

Objective: Over 480 000 Ukrainian refugees have arrived in the Czech Republic since the Russian invasion of Ukraine in 2022, including over 500 people with HIV. This study describes the demographics, characteristics, and management of Ukrainian refugees with HIV in the Czech Republic.

Design: Retrospective, observational, noninterventional study.

Preliminary report on the provision of HIV care to war refugees with HIV who are migrating from Ukraine: data from the ECEE Network Group.

The ECEE Network Group investigated early provision of HIV care to war refugees migrating from Ukraine in Central and Eastern Europe (CEE) through an online survey. Fourteen countries admitting war refugees from Ukraine on March 31, 2022, completed the survey. Most centers (86%) organized provision of same day antiretroviral therapy (ART) for at least 30 days (77%), but indicated that it may affect the local HIV care.

Retrospective Analysis Revealed an April Occurrence of Monkeypox in the Czech Republic.

Herein, we present our findings of an early appearance of the Monkeypox virus in Prague, Czech Republic. A retrospective analysis of biological samples, carried out on the 28th of April, revealed a previously unrecognized case of Monkeypox virus (MPxV) infection. Subsequent data analysis confirmed that the virus strain belongs to the ongoing outbreak.

Monkeypox and Herpes Simplex Virus Type 2 Coinfection: Case Report of Perianal Lesions in HIV-Positive Patient.

We report a case of monkeypox and herpes simplex type 2 coinfection in an HIV-positive male patient who has sex with men. This case report describes a diagnostic approach for papular rash in the anal area of the male patient who has sex with men with a history of sexually transmitted disease. This is also the first documented case of monkeypox in the Czech Republic, which was confirmed after a retrospective review of swab samples from a previously hospitalized HIV-positive patient.

Acute phase of COVID-19 is associated with elevated plasmablasts in the blood.

Objectives: The study was aimed at the characterization of humoral immunity in acute SARS-CoV-2 infection.

Background: Humoral immunity plays a central role in the protection from infection due to SARS-CoV-2, causative agent of coronavirus diseases 2019 (COVID-19).

Patients And Methods: In 24 adult patients hospitalized with COVID-19, the functional subsets of circulating B-lymphocytes and SARS-CoV-2 specific IgA and IgG antibodies were analyzed using a flow cytometry and immunoassays, respectively.

[A Case of a patient with AIDS and pneumocystis pneumonia complicated by cytomegalovirus pneumonitis].

We report a case of a 39-year-old male admitted for respiratory failure. On admission, the patient was diagnosed with advanced HIV infection and Pneumocystis jirovecii pneumonia (PJP). The patient's condition improved following specific PJP therapy but then deteriorated.

Antiretroviral treatment of HIV infection does not influence HIV-specific immunity but has an impact on non-specific immune activation.

HIV-specific and non-specific immune responses are crucial in the immunopathogenesis of HIV infection. Therefore, the objective of our study was to analyse the frequency and functional status of HIV-specific CD8+ T cells and the expression of non-specific activation markers on CD8+ T cells in HIV+ patients, and to assess the effects of combined antiretroviral treatment (cART). We examined 28 HIV+ patients, including 13 patients not receiving therapy and 15 patients on cART therapy using ELISpot assay and flow cytometry with intracellular and MHC tetramer staining.

[Selected aspects of the immunopathogenesis of HIV infection].

This review describes a current view on immunopathogenesis of HIV infection including potential causes of immune failure in control of the infection. Above all, the role of different components of immune system is being discussed. Their interplay is disturbed during interaction with the virus and determines the course of the infection.
