Abstract
Infections caused by parasites and fungi can trigger the cytokine storm syndrome (CSS). These infections causing CSS can occur together with acquired immunodeficiencies, lymphomas, the use of immunosuppressive medications, transplant recipients, cancer, autoinflammatory, and autoimmune diseases or less frequently in healthy individuals. Histoplasma, Leishmania, Plasmodium, and Toxoplasma are the most frequent organisms associated with a CSS. It is very important to determine a previous travel history when evaluating a patient with a CSS triggered by these organisms as this may be the clue to the causal agent. Even though CSS is treated with specific therapies, an effort to find the causal organism should be carried out since the treatment of the infectious organism may stop the CSS. Diagnosing a CSS in the presence of parasitic or fungal sepsis should also lead to the study of an altered cytotoxic or hemophagocytic response in the susceptible host.

Abstract
Here, we describe the case of a naïve HIV late presenter female African patient with progressive disseminated histoplasmosis and a severe life-threatening clinical picture in a non-endemic area. She had not visited Africa in the past decade. She developed a reactive hemophagocytic lymphohistiocytosis and an acute psychiatric disorder. Histoplasmosis was diagnosed after two bone marrow biopsies. Therapy with liposomal amphotericin B resulted in rapid and progressive improvements in blood examinations and clinical conditions, including the disappearance of psychiatric disorders. The characteristics of our case were compared with those of all other cases of hemophagocytic syndrome secondary to histoplasmosis in HIV-positive patients reported in PubMed. In conclusion, clinicians outside endemic areas should evaluate histoplasmosis as a cause of severe clinical picture, especially in a patient with a travel history to an endemic area, even after many years, considering the possible reactivation of latent infection.

Clin Med Insights Pathol 2022; 15:2632010X221118059. [PMID: 36051652 PMCID: PMC9425888 DOI: 10.1177/2632010x221118059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Accepted: 07/15/2022] [Indexed: 11/18/2022] Open
Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a disorder that occurs due to unsuitable monocyte activation in a variety of infections. In human immunodeficiency virus (HIV) infections, patients with advanced immunossupression associated with opportunistic infections are at increased risk of developing HLH. We describe a clinical case of a 33-year-old male student diagnosed with HIV who was hospitalized for investigation of asthenia and dyspnea, accompanied by adynamia, decreased motor force in the left leg, dysphagia, and dysfluency. His general condition was regular, he was pale, feverish, and had normal cardiac and pulmonary auscultation. Physical examination revealed ulcerated lesions in the perianal region and hepatosplenomegaly without palpable lymph node enlargement. Laboratory parameters showed pancytopenia, a slight increase in liver function accompanied by high lactate dehydrogenase, and hiperferritinemia. The initial diagnosis was disseminated histoplasmosis, thus amphotericin B deoxycholate was empirically prescribed while waiting on myeloculture and blood cultures for fungi and mycobacteria. Other clinical procedures were blood transfusion, resumption of antiretroviral therapy (ART) and secondary prophylaxis. Myeloculture blood cultures of fungi and mycobacteria were negative. Patient evolved well in relation to the initial complaints and showed partial clinical and laboratory improvement. However, 23 days after hospitalization, he developed a febrile episode accompanied by chills and a convulsive crisis. The patient was transferred to the intensive unit care and developed septic shock and respiratory failure. He died 25 days after the onset of the condition. After the postmortem examination, histopathology revealed countless rounded fungal structures compatible with Histoplasma sp., which were observed in the peripancreatic lymph node, liver, and spleen, in addition to hemophagocytosis in the splenic parenchyma. We thus conclude that when the patient met criteria for HLH, such as fever, hepatosplenomegaly, hiperferritinemia, and pancytopenia, the evolution was fast due to the aggressive and rapidly fatal nature of HLH, despite anti-fungal and corticoid treatment. Therefore, this case report reinforces the need to consider hemophagocytic syndrome in patients with HIV and disseminated histoplasmosis, especially where histoplasmosis is highly endemic, in order for the treatment be started early when there is high clinical suspicion.

Abstract
Introduction: Haemophagocytic Lymphohistiocytosis (HLH), during HIV infection is a rare complication with a poor prognosis. There are few data on HLH within the Amazon region. The objective was to describe epidemiological, clinical and therapeutic features of HIV-related HLH in French Guiana. Methods: A retrospective analysis of adult HIV patients at Cayenne hospital with HLH between 2012 and 2015. A diagnosis of HLH was given if the patient presented at least 3 of 8 criteria of the HLH-2004 classification. Results: Fourteen cases of HLH were tallied during the study period. The mean age was 46 years with a sex ratio of 1.8. The most frequent etiology of HLH was an associated infection (12/14). Confirmed disseminated histoplasmosis, was found in 10 of 14 cases, and it was suspected in 2 other cases. The CD4 count was below 200/mm3 in 13/14 cases. An HIV viral load >100,000 copies/ml was observed in 13/14 cases. An early treatment with liposomal amphotericin B was initiated in 12/14 cases. The outcome was favorable in 12/14 of all cases and in 10/12 cases involving histoplasmosis. Case fatality was 2/14 among all cases (14.3%) et 1/10 among confirmed disseminated histoplasmosis with HLH (10%). During the study period 1 in 5 cases of known HIV-associated disseminated histoplasmosis in French Guiana was HLH. Conclusion: Histoplasmosis was the most frequent etiology associated with HLH in HIV-infected patients in French Guiana. The prognosis of HLH remains severe. However, a probabilistic empirical first line treatment with liposomal amphotericin B seemed to have a favorable impact on patient survival.

Abstract
Background Histoplasmosis is an endemic fungal disease with diverse clinical presentations. Histoplasmosis-associated hemophagocytic lymphohistiocytosis (HLH) is a rare disorder with limited data regarding treatment and outcome. We described the clinical features, treatment, and outcomes of five patients in our institution with histoplasmosis-associated HLH. This review also summarizes the current literature about presentation, treatment, and outcome of this infection-related HLH entity. Methods We searched the electronic medical records for patients with histoplasmosis-associated HLH at our institution from 1/1/2006 to 9/30/2017. Diagnosis of HLH was confirmed by chart review using the HLH-04 criteria. We also searched the current literature for case reports and case series. Results Five cases of histoplasmosis-associated HLH were included from our institution. All five patients were diagnosed after 2010. The literature review yielded 60 additional cases of histoplasmosis-associated HLH. The most common underlying condition was HIV in 61% of cases. The majority of histoplasmosis patients (81%) were treated with amphotericin B formulations. Documented specific treatments for HLH were as follows: nine patients received steroids only, six patients received intravenous immunoglobulin (IVIG) only, three patients received dexamethasone and etoposide, two patients received etoposide, dexamethasone, and cyclosporine, two patients received steroids and IVIG, and one patient received Anakinra and IVIG. The inpatient case fatality rate was 31% with most of the deaths occurring within two weeks of hospital admission. Conclusions Histoplasmosis-associated HLH among adults is an uncommon but serious complication with high associated mortality. Early antifungal therapy with a lipid formulation amphotericin B is critical. The initiation of immunosuppressive therapy with regimens like HLH-04 in this disease entity should be individualized.

Abstract
Haemophagocytic lymphohistiocytosis (HLH) is a devastating syndrome due to uninhibited immune activation. Disseminated histoplasmosis is a rare cause of HLH. There have been few case reports and series demonstrating a relation between the two disease entities in immunosuppressed hosts. HLH secondary to disseminated histoplasmosis is even rarer in an immunocompetant host. We report a rare case of HLH triggered by disseminated histoplasmosis in an immunocompetant patient.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) in immunocompromised hosts is a fulminant syndrome of immune activation with high rates of mortality that may be triggered by infections or immunodeficiency. Rapid diagnosis and treatment of the underlying disorder is necessary to prevent progression to multiorgan failure and death. We report a case of HLH in a patient with human immunodeficiency virus, disseminated histoplasmosis, Mycobacterium avium complex, and Escherichia coli bacteremia. We discuss management of acutely ill patients with HLH and treatment of the underlying infection versus initiation of HLH-specific chemotherapy.

Abstract
We present the case of an 18-year-old male patient admitted with complaints of fever and rapid weight loss since 3 months. Patient had multiple umbilicated papular to nodular lesions over chin and forehead region. Complete blood count revealed bicytopenia. An excisional biopsy of the skin lesions had revealed cutaneous histoplasmosis. On further investigations for bicytopenia, histoplasmosis had been diagnosed on bone marrow trephine biopsy. For the immune status, patient's serology against HIV was negative and his CD4 lymphocyte counts were low at 161. Patient received antifungal therapy including amphotericin B and itraconazole. He showed remarkable improvement in his general condition and blood counts. A repeat CD4 count showed normal counts, and idiopathic CD4 lymphocytopenia was excluded. Disseminated histoplasmosis presenting as cutaneous lesions in an immunocompetent host is very rare, and we are not aware of any case report in the literature where there is reversible depletion of CD4 counts following antifungal treatment in an immunocompetent host of nonendemic area.

Abstract
Background. Histoplasmosis-associated hemophagocytic lymphohistiocytosis (HLH) is a relatively rare disorder for which data are limited regarding optimal treatment and clinical outcomes in adults. We describe the clinical features, treatment, and outcomes of patients with histoplasmosis-associated HLH at our institution. Methods. We performed a retrospective chart review of all inpatients at Parkland Hospital diagnosed with HLH associated with Histoplasma capsulatum from 2003 to 2013. Results. Eleven cases of histoplasmosis-associated HLH over this time period were identified. Nine of eleven cases were males (82%). Nine of these patients had human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), 1 was a renal transplant patient on immunosuppressants, and the other had no documented immunocompromise. The most common HLH criteria were splenomegaly (n = 10), fever (n = 10), and ferritin >500 ng/dL (n = 9). Urine Histoplasma antigen was positive in every patient tested (n = 9 of 9), and most antibodies for Histoplasma were positive if checked (n = 4 of 5). A majority of patients received liposomal amphotericin B (n = 9) with an average treatment duration of 11 days, and 5 patients also received prednisone, intravenous immunoglobulin (IVIG), or both. Overall, 5 patients died within 30 days (45.5%), and 7 patients died within 90 days (63.6%). Of the 5 patients that received immunosuppression, 4 died (80%), whereas in the group not given additional immunosuppression (n = 5), 2 died (40%). Conclusions. Histoplasmosis-associated HLH among adults is a lethal disease of highly immunocompromised patients, especially patients with HIV/AIDS. Clinical features such as splenomegaly, elevated ferritin, and cytopenias should prompt evaluation for HLH in this population. Further data are needed to define the role of immunosuppression, IVIG, and highly active antiretroviral therapy in treating this condition.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is traditionally regarded as a rapidly progressive and often fatal illness. In patients with AIDS, HLH usually occurs secondary to opportunistic infections. Although popular guidelines exist for the diagnosis and management of HLH in general, no formal study has evaluated their applicability among adult patients who develop HLH in the setting of AIDS and opportunistic infections. The study reports on a case of HLH in a patient with AIDS and disseminated histoplasmosis. Eighteen other previously reported cases of HLH in the setting of AIDS and histoplasmosis were reviewed. Majority of the cases occurred in patients with a CD4 count of less than 70 cells/mm(3). Overall mortality was 44%. Not getting antifungal treatment and having Histoplasma in blood were the 2 main risk factors for death. Among the patients who had a timely diagnosis of histoplasmosis and were initiated on antifungal therapy, the survival rates were significantly better, especially in the post-2000 ad period.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) covers a wide array of related life-threatening conditions featuring ineffective immunity characterized by an uncontrolled hyperinflammatory response. HLH is often triggered by infection. Familial forms result from genetic defects in natural killer cells and cytotoxic T-cells, typically affecting perforin and intracellular vesicles. HLH is likely under-recognized, which contributes to its high morbidity and mortality. Early recognition is crucial for any reasonable attempt at curative therapy to be made. Current treatment regimens include immunosuppression, immune modulation, chemotherapy, and biological response modification, followed by hematopoietic stem-cell transplant (bone marrow transplant). A number of recent studies have contributed to the understanding of HLH pathophysiology, leading to alternate treatment options; however, much work remains to raise awareness and improve the high morbidity and mortality of these complex conditions.

Abstract
Systemic causes of cholestasis constitute a diverse group of diseases across organ systems. The pathophysiology of cholestasis in systemic disease can be a consequence of direct involvement of a disease process within the liver or extrahepatic biliary system or secondary to immune-mediated changes in bile flow. Evaluating a patient with cholestasis for a systemic cause requires an understanding of the patient's risk factors, clinical setting (eg, hospitalized or immunosuppressed patient), clinical features, and pattern of laboratory abnormalities.

Abstract
OBJECTIVE This review aims to help critical care clinicians maintain a high level of suspicion regarding the diagnosis of Hemophagocytic Histiolymphocytosis (HLH). It describes the clinical and laboratory features of HLH, outlines its pathophysiology and reviews the most frequent etiologies related to HLH. Prognostic factors and therapeutic options are also reported. DATA SOURCES Review of the literature. RESULTS The diagnosis of HLH relies on the association of clinical abnormalities and hemophagocytosis in bone marrow, spleen, or lymph node specimens. Liver, pulmonary, renal, cardiac and skin involvement may occur at various degrees possibly leading to multiple organ failure. Three main etiologies can be found, namely infections, lymphoproliferative diseases, or connective tissue diseases. Immune deficiency is often retrieved. Mortality can be as high as 50%. Although clinically mimicking severe sepsis, HLH has a distinct pathophysiology on which specific therapy is based. Early diagnosis and treatment is mandatory to increase the chances of survival. CONCLUSION The comprehensive management of severe HLH requires the involvement of a multidisciplinary team in order to determine the best therapeutic strategy and to identify the underlying cause.

Abstract
We report a case of disseminated histoplasmosis in a 33-year old Ecuadorian patient with AIDS and a CD4 lymphocyte count of 39 cells/microl. He presented with prolonged fever and cough, was diagnosed with hemophagocytic syndrome and multiple organ failure and died 18 days after admission. Histoplasma capsulatum was isolated post-mortem from bone marrow biopsy and blood culture. In a literature review we found 22 published cases of disseminated histoplasmosis in patients with AIDS in Spain since 1988. All but two were men under 50 years old. Nineteen had been born or had lived in endemic areas. The diagnosis of histoplasmosis was established by culture of bone marrow biopsy in 10 cases. Itraconazole was introduced as a second drug after amphotericin B in ten of the thirteen patients who survived.

Abstract
Reactive hemophagocytic syndrome (RHS) is an uncommon life-threatening disorder. It is believed to be caused by widespread non-neoplastic proliferation and inappropriate activation of mature macrophages, resulting in excessive cytokine activation which leads to hematophagocytosis by cells of the macrophage-monocyte lineage and multiorgan dysfunction. RHS may be associated with infections caused by bacterial, viral and fungal organisms as well as lymphoproliferative disorders, nonhematopoietic malignancies, autoimmune diseases and some therapeutic drugs. Immunosuppression is a frequent underlying condition in RHS. The following case presentation describes a patient with a history of chronic hepatitis C, cryoglobulinemia, renal failure and Staphylococcus aureus perinephric abscess and bacteremia, who, at autopsy, was found to have disseminated histoplasmosis with fungal endocarditis and RHS.

Abstract
The following case illustrates an ileal perforation and reactive hemophagocytic syndrome (RHS) resulting from disseminated histoplasmosis in a patient with Human Immunodeficiency Virus (HIV) from Puerto Rico. Although the diagnosis was established by histopathologic findings and a positive bone marrow culture, Histoplasma capsulatum-specific real-time Polymerase Chain Reaction (PCR) allowed to confirm the diagnosis from formalin-fixed, paraffin-embedded tissue. Interestingly, the Histoplasma antigens in both serum and urine samples were falsely negative. Amphotericin B lipid complex (Abelcet), followed by oral itraconazole, led to a successful response and resolution of symptoms. A short review of the clinical signs and symptoms, diagnostic tests, and therapeutic options for disseminated histoplasmosis is done, with emphasis on the role of Histoplasma-specific real-time PCR as a molecular diagnostic tool and the efficacy of treatment with one of the lipid formulations of amphotericin B.

Abstract
Leukoerythrophagocytosis by sinus histiocytes in the lymph nodes is a rare cytological observation. Though often seen in lymph nodes draining malignancies, one may occasionally encounter them in vascular lesions. We report a case of leukoerythrophagocytosis by sinus histiocytes of the right supraclavicular lymph nodes in a 35-yr-old male. He presented with a painful soft tissue mass in the right anterior region of the chest wall extending into the axilla of 6 mo duration. Bilateral radial pulsations were absent. The patient had received treatment for pulmonary tuberculosis 1 yr ago. FNAC of the soft tissue mass revealed only blood. Radiological evaluation revealed a vascular lesion, with smooth borders, extending into the upper zone of right lung and displacing the second rib inferiorly. Doppler evaluation confirmed it to be a right subclavian aneurysm with arteritis.

Abstract
We present a case of hemophagocytosis in the setting of a disseminated Histoplasma infection in a patient with B-cell chronic lymphocytic leukemia (CLL). A 68-year-old man with CLL presented with progressive pancytopenia and fevers after therapy with cyclophosphamide and fludarabine phosphate. Extensive evaluation for a source of infection revealed a pulmonary nodule. A biopsy specimen taken from the nodule showed granulomas containing Histoplasma organisms. A bone marrow biopsy specimen demonstrated disseminated histoplasmosis and intense hemophagocytosis. Antifungal therapy with amphotericin B was initiated, and the fevers and cytopenias resolved. Hemophagocytic syndrome is an uncommon condition with many origins. It is characterized by a proliferation of histiocytes with phagocytosis of formed elements of blood. Clinical manifestations include signs and symptoms of immune activation and decreased peripheral blood cell counts. This condition is often underdiagnosed because clinicians are unfamiliar with it.

Abstract
The case of a 22-yr-old male who after a brief febrile episode developed autoimmune hemolytic anemia and right pulmonary infiltrate with pleural effusion is presented. Cytologic examination of the pleural fluid revealed lymphocytosis and hemophagocytosis, primarily of red blood cells (RBCs) by mature histiocytes. There was accompanying splenomegaly, laboratory evidence of hepatic dysfunction, and retroperitoneal lymphadenopathy. Besides profound reduction of red blood cells in the peripheral blood, there was reduction of lymphocytes and platelets. As a neoplastic process was ruled out by bone marrow and pleural biopsies, the disease was considered to be virus-induced and was halted and progressively regressed with early institution of vigorous antiinflammatory therapy with adrenocortical steroids. Upon reviewing the case, examination of the bone marrow biopsy disclosed limited hemophagocytosis of RBCs and lymphocytes by histiocytes and considerable viral cytopathic effect on hematopoietic cells (red and white cell precursors and megakaryocytes), which by appropriate immunolabelling was identified as induced by Epstein-Barr virus. A virus-related acquired hemophagocytic syndrome in its early stages was probably present, yet an undesirable clinical outcome was averted by early institution of vigorous steroid therapy. The need to recognize early hemophagocytic changes in cytologic specimens for early institution of appropriate therapy is emphasized. The possibility of erythrophagocytosis, also manifested during the course of an autoimmune hemolytic process and unrelated to hemophagocytic syndrome, is discussed.
