Epstein-Barr virus (EBV) induced hemophagocytic syndrome followed by EBV associated T/NK lymphoma in a child with perinatal human immunodeficiency virus (HIV) infection

Haemophagocytic lymphohistiocytosis in human immunodeficiency virus: a systematic review of literature

Diagnosis and management of hemophagocytic lymphohistiocytosis (HLH) in patients with human immunodeficiency virus (HIV) infection are scarcely described in the published literature. The aim of this systematic review was to delineate the triggers of HLH in patients with HIV and understand the role of steroids in the management. We conducted a comprehensive search of English medical literature via the Medline ⁄ PubMed database using different synonyms of "HIV" AND "HLH". The review was registered in PROSPERO (CRD42018099987). The titles and abstracts of the 185 articles between January 1986 and April 2018 were reviewed. The final analysis was done from 42 articles with 52 patients. HLH was associated with malignancy in 17 patients, while infection was found in 25 patients. No cause was identified in eight patients, out of which four had acute HIV infection. Death was reported in 21 patients. Presence of either malignancy (p = 0.051) or opportunistic infection (p = 0.69) was not associated with increased chances of death by univariate analysis. A total of 26 patients were treated with steroids, while etoposide was used in only four patients. Administration of steroids as a treatment of HLH was associated with more chances of death (p = 0.048). Malignancy and Opportunistic infections are important triggers for HLH in patients with HIV. Acute HIV by itself can act as a trigger for HLH. Evidence on the use of steroids as a treatment of HLH in patients with HIV is not convincing.

NK/T cell non-Hodgkin lymphoma in a HIV-positive patient

NK/T lymphomas have rarely been reported in HIV/AIDS patients. Here we report a case of a 37-year-old woman, with AIDS and a recent diagnosis of Kaposi sarcoma in a mesenteric lymph node, who presented with extra-ocular nerve palsies and gastrointestinal bleeding. A small intestine resection specimen revealed an extra-nodal NK/T cell lymphoma, nasal type. The unique presentation of this rare and aggressive lymphoma in the setting of AIDS and Kaposi sarcoma underscores the importance of maintaining a broad differential diagnosis when evaluating a malignant neoplasm from a HIV-positive patient.

Haemophagocytic syndrome and HIV

PURPOSE OF REVIEW

Haemophagocytic syndrome (HPS) is a relatively rare complication of HIV infection but one that can take a particularly aggressive and potentially fatal course. The condition may be underrecognized due to the nonspecific nature of the clinical features. This review summarizes the pathogenesis, clinical and diagnostic features, common associations and current options in the management of HPS in the context of HIV infection, with the aim of increasing diagnostic awareness and facilitating early intervention.

RECENT FINDINGS

Our understanding of HPS is being increasingly informed by research into the molecular basis of the familial forms of the condition. The list of associated infections and neoplasms continues to lengthen, although the occurrence of HPS is increasingly recognized in the context of HIV infection alone, occasionally as its initial presentation in acute seroconversion. Diagnostic guidelines have recently been refined and attempts to adapt these to particular patient groups are ongoing. Management of HIV-associated HPS is adapted to the clinical context and may involve treatment of an underlying disorder or immunosuppressive therapy to reduce the activation of macrophages and T cells.

SUMMARY

The spectrum of HIV-related lymphoproliferative disorders continues to expand. Our understanding of their molecular and cellular basis and the role of infectious organisms in their development increasingly shapes and advances our clinical management of these complex conditions.

Reactive hemophagocytosis associated with the initiation of highly active antiretroviral therapy (HAART) in a patient with AIDS

Reactive hemophagocytosis has been associated with neoplasia, bacteria, parasitic, and viral infections including human immunodeficiency virus (HIV). Here we present a case of reactive hemophagocytosis associated with the initiation of highly active antiretroviral therapy (HAART), probably representing a syndrome termed the immune reconstitution inflammatory syndrome (IRIS) or immune reconstitution syndrome.

Hemophagocytic syndrome: an unusual manifestation of acute human immunodeficiency virus infection

An 18 year-old heterosexual man was hospitalized because of fever, chills, a sore throat, and a dry cough for 8 days. He had had sexual intercourse with a new partner within the 4 months prior to admission. At admission, the patient presented a clinical picture compatible with hemophagocytic syndrome (HPS). The presence of hemophagocytosis was subsequently determined pathologically from bone marrow and lymph node specimens. An exhaustive diagnostic work-up failed to reveal any causative etiology, the symptoms improving after 2 doses of intravenous immunoglobulin (IVIG) infusion, given at a dose of 0.5 mg/kg each, the 2 doses being administered 1 week apart. Three months subsequent to the patient's initial presentation, acute human immunodeficiency virus (HIV) infection was diagnosed, and the patient received highly active antiretrovirus therapy (HAART) from the time of diagnosis. The patient remained well for the following 2 years. HPS in the advanced stages of HIV infection has previously been described, but HPS during seroconversion of an acute form of the infection is rare. We most definitely suggest, however, that acute HIV infection be included in the list of potential causes of HPS. IVIG therapy appears to be an appropriate therapeutic modality, and HAART also is effective, for prevention of recurrence of HPS in a patient with acute HIV infection.
