A 79-year-old woman of Mediterranean ascent suffered from corticosteroid-dependent chronic obstructive lung disease, hypogammaglobulinemia (IgG 1 and 2), decreased CD16 natural killer cell function and non-HIV related CD4 and CD8 lymphopenia. Such immunodeficiency could be either a variant of common variable immunodeficiency or an early stage of the idiopathic CD4 + T lymphocytopenia syndrome. She developed bilateral lesions of Kaposi's sarcoma on the lower extremities resembling the classic European type of the disease. The tumors contained both CD34 + and Factor XIIIa + cells. The HLA-DR5 haplotype was not found. Weekly low intravenous dosages of vinblastine improved the lesions but the patient died from pontic infarction.

Background: Multimorbidity is increasingly prevalent in lower- and middle-income countries. Health-related quality of life (HRQOL) has been inversely associated with multimorbidity but is understudied in lower- and middle-income countries. We report cardiovascular disease (CVD) multimorbidity in Haiti and its association with HRQOL.

Kaposi's sarcoma-associated herpesvirus (KSHV) is a human gammaherpesvirus associated with Kaposi's sarcoma and B cell malignancies. Like all herpesviruses, KSHV contains conserved envelope glycoproteins (gps) involved in virus binding, entry, assembly, and release from infected cells, which are also targets of the immune response. Due to the lack of a reproducible animal model of KSHV infection, the precise functions of the KSHV gps during infection are not completely known.

A 84-year old man who has a history of refractory Kaposi's sarcoma (KS) was treated with ALA-PDT combined with the dual 980-nm/1470-nm diode laser for 6 times every other week. Satisfactory result was noted without any unbearable adverse effects. The combination of the dual 980nm/1470nm diode laser and ALA-PDT may be an ideal strategy in treating local KS with good tolerance, especially in elder patients who can not tolerate radiotherapy and chemotherapy.

Background: HIV infection has been associated with an increased risk of cancer development and Kaposi's sarcoma, non-Hodgkin's lymphoma, and invasive cervical cancers have been a manifestation of AIDS. With the advent of antiretroviral therapy, a collateral appearance of non-AIDS defining cancers (NADC) has been observed in HIV positive patients.
Methods: From January 1997 to December 2022, we performed an observational cross-sectional study, involving HIV-infected outpatients with both AIDS-defining cancers (ADC) and NADC, followed up in a tertiary hospital in Italy.
