Clinicopathological Features and Mortality in Patients With Kaposi Sarcoma and HIV: A Retrospective Analysis of a Thirty-Year Study From a Peruvian Oncologic Center.

PURPOSE: Kaposi's sarcoma (KS) is a multifocal angioproliferative disease. In Peru, the implementation of the highly active antiretroviral treatment (HAART) program was in 2005, the model for treating patients with HIV-positive KS shifted to a potential cure. In this study, we aim to compare clinicopathological characteristics and prognostic factors associated with outcomes in patients with HIV-positive KS. METHODS: We developed a retrospective cohort study that includes patients with HIV/AIDS and KS seen in the Instituto Nacional de Enfermedades Neoplasicas between 1987 and 2017. Patients were divided into two groups according to the implementation of HAART in our country: the non-HAART group and those treated with HAART after 2005. Multivariate analysis for overall survival (OS) was performed with the Cox proportional hazard regression model. RESULTS: There was a greater visceral compromise and more extensive oral cavity involvement in the non-HAART group (60% 31.7%, P < .01). Regarding the immune status, there was a significant difference from the CD4 count at 1-year follow-up (73 v 335, P = .01). The CD4/CD8 rate were significant different before QT (0.23 v 0.13, P = .01) and at 1-year follow-up (0.12 v 0.32, P = .03.). The estimated 5-year OS rate was significantly lower (P = .0001) for the non-HAART group (41.7%; 95% CI, 25.9 to 56.9) compared with the HAART group (79.3%; 95% CI, 66.8 to 87.5). In the multivariate model for OS, full-HAART regimen and previous diagnosis of HIV/AIDS (P < .01) were significantly associated with longer survival. CONCLUSION: Clinical and demographic characteristics of our patients are compatible with the literature, but we report a higher rate of gastrointestinal involvement. Furthermore, our findings provide evidence for the importance of HAART and its ability to reduce KS-related mortality.

Prevalencia de marcadores infecciosos y factores asociados en donantes de un banco de sangre peruano / Prevalence of infection markers and associated factors in donors of a peruvian blood bank

RESUMEN Se buscó determinar la prevalencia de marcadores infecciosos en donantes de un banco de sangre en Perú y valorar si las variables sociodemográficas del donante se asocian con la presencia de estos marcadores. Se realizó un estudio transversal analítico en 5942 donantes de un banco de sangre durante el 2018. Se determinó la positividad a inmunodeficiencia humana (VIH), hepatitis B (VHB), hepatitis C (VHC) y HTLV I-II; además de sífilis y enfermedad de Chagas. La prevalencia de VIH fue 0,81%, VHB 6,19%, VHC 0,12%, HTLV I-II 0,66%, enfermedad de Chagas 2,76% y sífilis 1,73%. Diversos factores sociodemográficos se asociaron con la positividad de marcadores infecciosos. El tipo de donación predominante fue no voluntaria (96%) y el 53% presentó historia de donación previa. Las prevalencias de marcadores infecciosos de VIH, VHB, enfermedad de Chagas y sífilis en los donantes de sangre fueron altas comparadas con otros países de la región.

ABSTRACT We aimed to determine the prevalence of infection markers in donors of a Peruvian blood bank and to assess whether donor sociodemographic variables are associated with the presence of these markers. An analytical cross-sectional study was carried out in 5942 donors of a blood bank, whose data was collected during 2018. Positivity to human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and HTLV I-II was determined, in addition to syphilis and Chagas disease. The prevalence of HIV was 0.81%; for HBV it was 6.19%; for HCV, 0.12%; for HTLV I-II, 0.66%; for Chagas disease, 2.76% and for syphilis it was 1.73%. Several sociodemographic factors were associated with infection markers positivity. The predominant donation type was non-voluntary (96%) and 53% had history of previous donation. The prevalence of infection markers for HIV, HBV, Chagas disease and syphilis in blood donors was high compared to other countries in the region.
