Abstract
Introduction: Lymph node enlargement can be present at any stage of the HIV infection, reactive to HIV itself, another infection, or a malignant source. The aim of our study was to describe the causes of lymphadenopathy in the people living with HIV (PLHIV) of French Guiana, a French territory in the Amazon region.
Methods: A retrospective multicenter case series was conducted between January 2005 and December 2021. Inclusion population consisted of PLHIV who underwent a fine needle aspiration or a biopsy of a lymph node that was analyzed at the Department of Pathology of Cayenne hospital.
Results: We included 152 adults, with a median age of 43 [35-51] years and median CD4 count of 185/mm3 [60-344]. The main causes of lymphadenopathy were: histoplasmosis (25%, CI95%: 18-33), followed by tuberculosis (24%, CI95%: 18-32), HIV-reactive lymphadenitis (21%, CI95%: 15-29) and lymphoproliferative disorder (11%, CI95%: 7-18). Multiple causes were present in 6% of cases. Opportunistic infections represented 53% (CI95%: 44-61) of cases. The main characteristics associated with opportunistic disease (infectious or neoplastic) were lymph node > 5 cm, CD4 count < 200/mm3, hepatomegaly or splenomegaly and the presence of extra-ganglionic symptoms.
Conclusion: For the last 17 years, opportunistic infections represented 53% of the causes of lymphadenopathy among PLHIV. Histoplasmosis, already recognized as the first AIDS-defining condition and first cause of AIDS-related deaths in French Guiana, is also the first cause of lymphadenopathy in PLHIV, ahead of tuberculosis and reactive lymphadenopathy. The CD4 count and the size of the lymph nodes appear to be the most important factors in the diagnostic process and should lead to a quick lymph node analysis in these patients.
期刊介绍:
PLOS Neglected Tropical Diseases publishes research devoted to the pathology, epidemiology, prevention, treatment and control of the neglected tropical diseases (NTDs), as well as relevant public policy.
The NTDs are defined as a group of poverty-promoting chronic infectious diseases, which primarily occur in rural areas and poor urban areas of low-income and middle-income countries. Their impact on child health and development, pregnancy, and worker productivity, as well as their stigmatizing features limit economic stability.
All aspects of these diseases are considered, including:
Pathogenesis
Clinical features
Pharmacology and treatment
Diagnosis
Epidemiology
Vector biology
Vaccinology and prevention
Demographic, ecological and social determinants
Public health and policy aspects (including cost-effectiveness analyses).
