Four HIV-1-infected patients presented with unusual clinical manifestations in the course of disseminated histoplasmosis, including liver abscesses, compressive lymphadenitis, intestinal obstruction, uveitis and arthritis within a median of 45 days after initiation of highly active antiretroviral therapy (HAART). They had a median increase of 106 CD4 cells/mul and granulomas with caseation in three. Partial immune reconstitution induced by HAART during disseminated histoplasmosis either related to the variety capsulatum or duboisii may be associated with immune reconstitution inflammatory syndrome.

Background: Small cell lung cancer (SCLC) is initially highly sensitive to chemotherapy, which often leads to significant tumor reduction. However, the majority of patients eventually develop resistance, and the disease is further complicated by its "cold" tumor microenvironment, characterized by low tumor immunogenicity and limited CD8+ T cell infiltration. These factors contribute to the poor response to immunotherapy in many cases of extensive-stage SCLC (ES-SCLC).

Introduction: Inborn errors of immunity is a diverse group of rare diseases caused by over 400 genetic mutations affecting the immune system and increasing infection susceptibility, autoimmunity, and malignancy. Hematopoietic stem cell transplantation offers a curative option for some inborn errors of immunity, with haploidentical donors providing a viable alternative when identical donors are unavailable.
Objective: To determine survival, usefulness of weekly chimerism monitoring, immune reconstitution, and complications in patients with inborn errors of immunity who underwent haploidentical hematopoietic stem cell transplantation at a reference center in Colombia.

Highly active antiretroviral therapy (HAART) is imperative in managing human immunodeficiency virus (HIV) infections. HAART aims to inhibit viral replication and improve immunity. Antiretroviral therapy has led to significant improvement in CD4-T cell counts and reductions in viral load, leading to improved overall immune function, increased survival, and decreased frequency of opportunistic infections.

C-IRIS is primarily driven by an influx of pathological CD4 T cells, which triggers a hyperinflammatory response. The murine model of C-IRIS is a way to study the disease in mice and understand how the immune system triggers life-threatening outcomes in patients.

Purpose: To investigate ocular manifestation of immune reconstitution inflammatory syndrome (IRIS) in human immunodeficiency virus (HIV) patients after starting highly active antiretroviral therapy (HAART) and its relationship to T cell immunity.
Methods: HIV patients with ocular IRIS after HAART were retrospectively reviewed. Clinical presentations with previous opportunistic infection, duration from initiation of HAART to IRIS, blood CD4+, CD8+ T cell count, and HIV RNA copies before HAART and at IRIS were analyzed.
