Epidemiology, Clinical Manifestations, Treatment, and Outcome of Mucormycosis: A Review of 77 Cases From a Single Center in France.

Background: The aim of this study was to assess the epidemiology, clinical manifestations, and outcome of mucormycosis over 15 years in a single center in France. Methods: We conducted a retrospective analysis of all mucormycosis cases in our institution from 1 January 2006 to 31 December 2020 and analyzed patients' medical records, laboratory results, and treatment to describe the epidemiology, clinical manifestations, diagnosis, treatment, and outcome. Mucorales quantitative polymerase chain reaction (qPCR) for the diagnosis was implemented in 2015. Results: Seventy-seven mucormycosis cases were analyzed in 77 patients, with a median age of 54 years (60% male). Identified risk factors were hematological diseases (46 cases [60%]), solid malignancies (2 cases), solid organ transplants (3), burns (18), diabetes only (7), and trauma (1). Sites of infection were lungs (42%), sinus (36%), skin (31%), central nervous system (9%), liver (8%), others (6%), and disseminated (12%). Diagnosis remained difficult and qPCR contributed to mucormycosis diagnosis in 30% of cases. Among hematology patients, serum qPCR was the only positive test in 15% of cases. A mixed mold infection was diagnosed in 24 of 77 (31%) patients. Surgical treatment was undertaken in 43 (56%) cases. Most patients received liposomal amphotericin B (89%), with a combination therapy in 18 of 77 cases (23%). Three-month survival rate was 40% (95% confidence interval [CI], .30-.53]). As for treatment, adjunction of surgery (hazard ratio, 0.47 [95%CI, .25-.91); P = 0.02) was associated with lower mortality. Conclusions: Mucormycosis remained associated with high mortality, especially in the hematological and burn populations. Surgery in combination with antifungal treatment was associated with improved survival.

Attributable mortality of candidemia - Results from the ECMM Candida III multinational European Observational Cohort Study.

INTRODUCTION: Despite antifungal advancements, candidaemia still has a high mortality rate of up to 40%. The ECMM Candida III study in Europe investigated the changing epidemiology and outcomes of candidaemia for better understanding and management of these infections. METHODS: In this observational cohort study, participating hospitals enrolled the first ten consecutive adults with blood culture-proven candidemia. Collected data included patient demographics, risk factors, hospital stay duration (follow-up of 90 days), diagnostic procedures, causative Candida spp., management details, and outcome. Controls were included in a 1:1 fashion from the same hospitals. The matching process ensured similarity in age (10-year range), primary underlying disease, hospitalization in intensive care versus non-ICU ward, and major surgery within 2 weeks before candidemia between cases and controls. Overall and attributable mortality were described, and a survival probability for cases and controls was performed. RESULTS: One hundred seventy-one pairs consisting of patients with candidemia and matched controls from 28 institutions were included. In those with candidemia, overall mortality was 40.4%. Attributable mortality was 18.1% overall but differed between causative Candida species (7.7% for Candida albicans, 23.7% for Candida glabrata/Nakaseomyces glabratus, 7.7% for Candida parapsilosis and 63.6% for Candida tropicalis). Regarding risk factors, the presence of a central venous catheter, total parenteral nutrition and acute or chronic renal disease were significantly more common in cases versus controls. Duration of hospitalization, and especially that of ICU stay, was significantly longer in candidemia cases (20 (IQR 10-33) vs 15 days (IQR 7-28); p = 0.004). CONCLUSIONS: Although overall and attributable mortality in this subgroup analysis of matched case/control pairs remains high, the attributable mortality appears to have decreased in comparison to historical cohorts. This decrease may be driven by improved prognosis of Candida albicans and Candida parapsilosis candidemia; whereas candidemia due to other Candida spp. exhibits a much higher attributable mortality.

Risk Factors and Outcome Associated With Fungal Infections in Patients With Severe Burn Injury: 10-year Retrospective IFI-BURN Study.

BACKGROUND: In burn patients, skin barrier disruption and immune dysfunctions increase susceptibility to invasive fungal diseases (IFDs) like invasive candidiasis (IC) and invasive mold infections (IMI). We provide an in-depth analysis of IFD-related factors and outcomes in a 10-year cohort of severe burn patients. METHODS: This retrospective cohort study includes adult patients admitted to the burn intensive care unit (BICU) between April 2014 and May 2023 with total burn surface area (TBSA) ≥15%. Patients were classified as proven IFD according to EORTC/MSGERC criteria applicable for IC. Putative IMIs were defined with: ≥2 positive cultures from a skin biopsy/bronchoalveolar lavage or ≥2 positive blood specific-quantitative polymerase chain reactions (qPCRs) or a combination of both. RESULTS: Among 1381 patients admitted, 276 consecutive patients with TBSA ≥15% were included. Eighty-seven (31.5%; IC n = 30; IMI n = 43; both n = 14) patients fulfilled the criteria for probable/putative IFD. At Day 30 after the burn injury, the estimated cumulative incidence proven/putative (pr/pu) IFD was 26.4% (95% confidence interval [CI], 21.4%-31.8%). Factors independently associated with IFDs were TBSA, severity scores and indoor burn injury (ie, from confined space fire). Overall mortality was 15.3% and 36.8% in the no IFD, pr/pu IFD groups respectively (P < .0001). IFD was independently associated with a risk of death (hazard ratio [HR]: 1.94 for pr/pu IFD; 95% CI, 1.12-3.36; P = .019). CONCLUSIONS: This study describes twenty-first-century characteristics of IFDs in severe burn patients confirming known risk factors with thresholds and identifying the indoor injury as an independent factor associated to IFDs. This suggests a link to contamination caused by fire damage, which is highly susceptible to aerosolizing spores.

Characteristics and incidence of infections in patients with multiple myeloma treated by bispecific antibodies: a national retrospective study.

OBJECTIVES: Bispecific antibodies (BsAbs) are an effective treatment used in relapsed or refractory multiple myeloma. Despite a well-tolerated safety profile, infectious events appear to be frequent in clinical trials. Real-world data on epidemiology, characteristics, risk factors, and outcomes of infections in patients treated with BsAb are still needed. METHODS: A retrospective, multicentre study in BsAb-treated patients with multiple myeloma was performed in 14 French centres from December 2020 to February 2023. The primary objective was to describe the incidence of infections that required hospitalization, specific treatment, or adaptation in BsAb administration. RESULTS: Among 229 patients with multiple myeloma treated with BsAb, 153 (67%) received teclistamab, 47 (20%) received elranatamab, and 29 (13%) talquetamab. We reported a total of 234 infections, including 123 (53%) of grade of ≥3. Predominant infections affected the respiratory tract (n = 116, 50%) followed by bacteraemias (n = 36, 15%). The hospitalization rate was 56% (n = 131), and 20 (9%) infections resulted in death. Global cumulative incidence of the first infection was 70% in all patients, 73% in patients treated with B-cell maturation antigen-targeting, and 51% with GPRC5D-targeting BsAb. In univariate analyses, corticosteroids for cytokine release syndrome (CRS)/immune effector cell-associated neurotoxicity syndrome (ICANS) were associated with a higher risk of first infection (HR = 2.13; 95% CI, 1.38-3.28), whereas GPRC5D-targeting BsAb and anti-bacterial prophylaxis were associated with a lower risk (HR = 0.53; 95% CI, 0.3-0.94 and HR = 0.65; 95% CI, 0.46-0.9). Fine and Gray multivariate model found that only corticosteroids for CRS/ICANS were correlated with a higher risk of first infection (HR = 2.01; 95% CI, 1.27-3.19). DISCUSSIONS: The implementation of preventive measures that aim to mitigate the risk of infection under BsAb is pivotal, notably in patients who received corticosteroids for CRS/ICANS.

Bronchial aspirate obtained during bronchoscopy yields increased fungal load compared to bronchoalveolar lavage fluid in patients at risk of invasive aspergillosis and Pneumocystis pneumonia.

Bronchoalveolar lavage fluid (BALF) is a standard respiratory sample for diagnosing invasive fungal diseases like Pneumocystis pneumonia (PCP) and invasive pulmonary aspergillosis (IPA). However, procedural variations exist across medical centers and wards. This study aimed to compare the diagnostic potential of BALF and bronchial aspirate (BA) obtained during bronchoscopy in 173 patients suspected of fungal infections. A prospective observational study was conducted from April 2020 to November 2021. BALF and BA were collected during bronchoscopy and subjected to direct examination, fungal culture, Aspergillus fumigatus qPCR (AfqPCR), and Pneumocystis jirovecii qPCR (PjqPCR). Galactomannan detection was performed on BALF. Patients were classified based on established European Organization for Research and Treatment of Cancer (EORTC) criteria. Out of 173 patients, 75 tested positive for at least one test in BA or BALF. For Aspergillus, proportion of positive AfqPCR (14.5% vs. 9.2%; P < 0.0001) and fungal loads (Cq of 31.3 vs. 32.8; P = 0.0018) were significantly higher in BA compared to BALF. For Pneumocystis, fungal loads by PjqPCR was also higher in BA compared to BALF (Cq of 34.2 vs. 35.7; P = 0.003). BA only detected A. fumigatus and P. jirovecii in 12 (42.9%) and 8 (19.5%) patients, respectively. BA obtained during a BAL procedure can be a suitable sample type for increased detection of P. jirovecii and A. fumigatus by qPCR. The use of BA in diagnostic algorithms requires further investigation in prospective studies.

Bronchoalveolar lavage fluid (BALF) vs. bronchial aspirate (BA) for fungal diagnosis in 173 patients suspected of invasive fungal infection: BA showed higher fungal loads than in BALF by qPCR for the detection of Aspergillus fumigatus and Pneumocystis jirovecii.

Investigation of CryptoPS LFA-positive sera in patients at risk of cryptococcosis.

Cryptococcal antigen (CrAg) is a capsule polysaccharide antigen that can be detected in the fluids of patients with cryptococcal infections. Cryptococcal Antigen Latex Agglutination System (CALAS), enzyme-linked immunosorbent assays (EIA), and lateral flow assay (LFA) are the main methods available. Two main commercial LFA kits are available: CryptoPS (Biosynex, Illkirch Graffenstaden, France) and CrAg LFA (IMMY, Inc. USA). In our lab, we prospectively used CryptoPS as a screening tool in serum for confirmed positive results with CALAS. We investigated the rigor of the CryptoPS test in serum in a multicentric evaluation over 3 years. To improve the specificity of CryptoPS in serum, we additionally implemented and evaluated a pretreatment protocol before CryptoPS testing. A total of 43 serum samples collected from 43 patients were investigated. We found that the CryptoPS assay is hampered by a high rate of false-positive results in serum with a high rate of CryptoPS-positive but CrAg LFA-negative and CALAS-negative sera in patients with no proof of Cryptococcus infection (n = 29). Using a simple pretreatment procedure (5 min incubation at 100°C and centrifugation) we were able to reverse false-positive results, suggesting that there could be interferent material present in the serum. Pretreatment also impacted the CryptoPS results (negative result) in two patients with the cryptococcal disease, one with isolated antigenemia and one with cryptococcal meningitis. Comparing the titers obtained with CALAS and CrAg LFA, we noticed that the titer obtained with CrAg LFA was almost 10-fold higher than those with CALAS. This study showed that Biosynex CryptoPS in serum could give false-positive results even in the absence of cryptococcal disease. These could be reduced by applying an easy pretreatment procedure to the serum before testing, with little but existing impact on the sensitivity.

Lateral flow assays are useful to detect the cryptococcal antigen in human fluids. We investigated CryptoPS-positive results and observed that true false-positive results occurred. The false-positive results can be reduced by applying an easy pretreatment procedure.

Hepatosplenic Candidiasis in Patients With Hematological Malignancies: A 13-Year Retrospective Cohort Study.

Background: Hepatosplenic candidiasis (HSC) used to be reported in patients with acute myeloid leukemia (AML) without antifungal prophylaxis. The aim was to describe the clinical features and outcomes of HSC over the last 13 years in a single French hematology center. Methods: All patients diagnosed with HSC between 2008 and 2020 were included in a single-center retrospective cohort study. Data were collected from patient charts, and HSC was classified according to the 2020 European Organisation for Research and Treatment of Cancer/Mycoses Study Group definitions. Results: Sixty patients were included, with 18.3% proven, 3.3% probable, and 78.3% possible HSC according to the 2020 European Organization for Research and Treatment of Cancer Mycoses Study Group classification. Among them, 19 patients were treated for acute myeloid leukemia (AML), 21 for lymphomas, and 14 for acute lymphoblastic leukemia. HSC occurred in 13 patients after autologous stem cell transplantation for lymphoma. At HSC diagnosis, 13 patients were receiving antifungal prophylaxis. Candida colonization was present in 84.2%, with prior candidemia in 36.7% of cases. ß-D-glucans was positive in 55.8%, and 45.8% of tissue biopsies were contributive. First-line antifungal therapy was azoles in 61.7%, and steroids were associated in 45% of cases. At 3 months of follow-up, partial response to antifungal therapy was 94.2%. At last follow-up (mean, 22.6 months), 41 patients (68.3%) presented a complete hematological remission and 22 patients were deceased, none because of HSC. Conclusions: The epidemiology of HSC has changed in the last decade, with fewer cases occurring in the AML setting. A better identification of patients at risk could lead to specific prophylaxis and improved diagnosis.

Evaluation of Serum Mucorales Polymerase Chain Reaction (PCR) for the Diagnosis of Mucormycoses: The MODIMUCOR Prospective Trial.

BACKGROUND: Early diagnosis and prompt initiation of specific antifungal treatment are essential for improving the prognosis of mucormycosis. We aimed to assess the performance of serum Mucorales quantitative polymerase chain reaction (qPCR) for the early diagnosis and follow-up of mucormycosis. METHODS: We prospectively enrolled 232 patients with suspicion of invasive mold disease, evaluated using standard imaging and mycological procedures. Thirteen additional patients with proven or probable mucormycosis were included to analyze DNA load kinetics. Serum samples were collected twice-a-week for Mucorales qPCR tests targeting the Mucorales genera Lichtheimia, Rhizomucor, and Mucor/Rhizopus. RESULTS: The sensitivity was 85.2%, specificity 89.8%, and positive and negative likelihood ratios 8.3 and 0.17, respectively in this prospective study. The first Mucorales qPCR-positive serum was observed a median of 4 days (interquartile range [IQR], 0-9) before sampling of the first mycological or histological positive specimen and a median of one day (IQR, -2 to 6) before the first imaging was performed. Negativity of Mucorales qPCR within seven days after liposomal-amphotericin B initiation was associated with an 85% lower 30-day mortality rate (adjusted hazard ratio = 0·15, 95% confidence interval [.03-.73], P = .02). CONCLUSIONS: Our study argues for the inclusion of qPCR for the detection of circulating Mucorales DNA for mucormycosis diagnosis and follow-up after treatment initiation. Positive results should be added to the criteria for the consensual definitions from the European Organization for the Research and Treatment of Cancer/Mycoses Study Group Education and Research Consortium (EORTC/MSGERC), as already done for Aspergillus PCR.

Profiles and outcomes in patients with COVID-19 admitted to wards of a French oncohematological hospital: A clustering approach.

OBJECTIVES: Although some prognostic factors for COVID-19 were consistently identified across the studies, differences were found for other factors that could be due to the characteristics of the study populations and the variables incorporated into the statistical model. We aimed to a priori identify specific patient profiles and then assess their association with the outcomes in COVID-19 patients with respiratory symptoms admitted specifically to hospital wards. METHODS: We conducted a retrospective single-center study from February 2020 to April 2020. A non-supervised cluster analysis was first used to detect patient profiles based on characteristics at admission of 220 consecutive patients admitted to our institution. Then, we assessed the prognostic value using Cox regression analyses to predict survival. RESULTS: Three clusters were identified, with 47 patients in cluster 1, 87 in cluster 2, and 86 in cluster 3; the presentation of the patients differed among the clusters. Cluster 1 mostly included sexagenarian patients with active malignancies who were admitted early after the onset of COVID-19. Cluster 2 included the oldest patients, who were generally overweight and had hypertension and renal insufficiency, while cluster 3 included the youngest patients, who had gastrointestinal symptoms and delayed admission. Sixty-day survival rates were 74.3%, 50.6% and 96.5% in clusters 1, 2, and 3, respectively. This was confirmed by the multivariable Cox analyses that showed the prognostic value of these patterns. CONCLUSION: The cluster approach seems appropriate and pragmatic for the early identification of patient profiles that could help physicians segregate patients according to their prognosis.

Variable Correlation between Bronchoalveolar Lavage Fluid Fungal Load and Serum-(1,3)-ß-d-Glucan in Patients with Pneumocystosis-A Multicenter ECMM Excellence Center Study.

Pneumocystis jirovecii pneumonia is a difficult invasive infection to diagnose. Apart from microscopy of respiratory specimens, two diagnostic tests are increasingly used including real-time quantitative PCR (qPCR) of respiratory specimens, mainly in bronchoalveolar lavage fluids (BAL), and serum ß-1,3-d-glucan (BDG). It is still unclear how these two biomarkers can be used and interpreted in various patient populations. Here we analyzed retrospectively and multicentrically the correlation between BAL qPCR and serum BDG in various patient population, including mainly non-HIV patients. It appeared that a good correlation can be obtained in HIV patients and solid organ transplant recipients but no correlation can be observed in patients with hematologic malignancies, solid cancer, and systemic diseases. This observation reinforces recent data suggesting that BDG is not the best marker of PCP in non-HIV patients, with potential false positives due to other IFI or bacterial infections and false-negatives due to low fungal load and low BDG release.

Time to and differential time to blood culture positivity for assessing catheter-related yeast fungaemia: A longitudinal, 7-year study in a single university hospital.

BACKGROUND: Time to positivity (TTP) and differential time to positivity (DTTP) between central and peripheral blood cultures are commonly used for bacteraemia to evaluate the likelihood of central venous catheter (CVC)-related bloodstream infection. Few studies have addressed these approaches to yeast fungaemia. OBJECTIVES: This study aimed to evaluate TTP and DTTP to assess CVC-related yeast fungaemia (CVC-RYF). PATIENTS/METHODS: We retrospectively analysed the results from 105 adult patients with incident fungaemia, with CVC removed and cultured, collected from 2010 to 2017. The bottles were incubated in a BioMérieux BacT/ALERT 3D and kept for at least 5 days. RESULTS: Of the 105 patients included, most were oncology patients (85.7%) and had of long-term CVC (79.6%); 32 (30.5%) had a culture-positive CVC (defined as CVC-RYF) with the same species as in blood culture, and 69.5% had culture-negative CVC (defined as non-CVC-RYF, NCVC-RYF). Candida albicans represented 46% of the episodes. The median TTP was statistically different between CVC-RYF and NCVC-RYF (16.8 hours interquartile range (IQR) [9.7-28.6] vs 29.4 hours [IQR 20.7-41.3]; P = .001). A TTP <10 hours had the best positive likelihood ratio (21.5) for CVC-RYF, although the sensitivity was only 28%. DTTP was available for 52 patients. A DTTP >5 hours had a sensitivity of 100% and a specificity of 71% for CVC-RYF. CONCLUSIONS: Since the median TTP was 17 hours and the most performing DTTP >5 hours, these delays are too long to take a decision in the same operational day. More rapid methods for detecting infected catheters should be tested to avoid unnecessary CVC withdrawal.

Hepatitis Rebound after Infection with Yellow Fever Virus.

In 2018, yellow fever with hepatitis was diagnosed for 2 unvaccinated travelers returning to France from Brazil. Hepatitis persisted for >6 months; liver enzyme levels again increased 2 months after disease onset with no detection of yellow fever virus RNA or other pathogens. Persistent hepatitis with hepatic cytolysis rebound probably resulted from immune response.

Classic and extracavitary primary effusion lymphoma in 51 HIV-infected patients from a single institution.

Human immunodeficiency virus (HIV)-associated primary effusion lymphoma (PEL) is a rare B-cell non-Hodgkin lymphoma with poor prognosis. Lymphoma cells are always infected with human herpesvirus-8 (HHV-8) and in most cases coinfected with Epstein-Barr virus. In classic presentation, PEL is characterized by body cavity effusions with or without mass lesions. A variant with only extracavitary localization has also been described. We report on a large single-center series of patients with PEL in the era of combined antiretroviral therapy (cART). The main objective was to compare the characteristics and the outcome of patients with classic (n = 34) and extracavitary (n = 17) variant PEL. At PEL diagnosis, no major difference was observed between the two groups in terms of demographic and HIV characteristics. Extracavitary localizations were exclusively nodal in six patients and involved various organs in 11 patients. Another HHV-8-associated disease was observed in 31 patients, Kaposi sarcoma in 25, and multicentric Castleman disease in 18 patients, without difference between the two groups. Thirty-two patients were treated with CHOP associated with high-dose methotrexate, 13 were treated with CHOP-derived regimen alone, and six patients received low-dose/no chemotherapy. Complete remission was achieved in 21 (62%) and seven (41%) patients of the classic and extracavitary groups, respectively. The median overall survival (OS) was 10.2 months. Despite a higher disease-free survival in the extracavitary group, there was no difference in OS between the two variants. Based on this series, characteristics of classic and extracavitary variants were very close. Although prognosis of PEL remains very severe in cART era, the median survival compares favorably with earlier series.

Relevance of EORTC Criteria for the Diagnosis of Invasive Aspergillosis in HIV-Infected Patients, and Survival Trends Over a 20-Year Period in France.

BACKGROUND: Before the advent of combination antiretroviral therapy (cART), roughly 50% of cases of invasive aspergillosis (IA) associated with human immunodeficiency virus (HIV) infection involved individuals without classical predisposing host factors, and the median survival time was <4 months after diagnosis. We examined if the situation evolved over time using the revised European Organisation for Research and Treatment of Cancer/National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC) definition and analyzed survival trends after diagnosis over 20 years. METHODS: A data review committee evaluated 342 medical records that mentioned IA in the French Hospital Database on HIV. Validated cases were classified as fulfilling the EORTC criteria or otherwise as "HIV-related IA." Three periods were analyzed: pre-cART (before 1996), cART era prevoriconazole (1996-2001), and 2002-2011. RESULTS: Among 242 validated cases of IA, 124 (51%) fulfilled the EORTC criteria (EORTC-IA) and 118 (49%) were classified as "HIV-related," with similarly low CD4 cell counts in both groups. The proportion of EORTC-IA cases remained stable across the 3 periods (50%, 48%, and 54%, respectively). The 3-month survival rate improved after the advent of cART (38% vs 69%), with no difference between EORTC-IA and HIV-related IA (hazard ratio [HR], 1.2 95% confidence interval [CI] {0.7-1.8}). Voriconazole exposure decreased mortality in 2002-2011 (HR, 0.1 95% CI [0.01-0.8]). CONCLUSIONS: In the cART era, EORTC criteria, developed for use in hematology/oncology, still applied to only half the cases diagnosed among HIV-infected patients. A rapid diagnosis of IA is paramount to improve survival. For patients who do not fulfill the EORTC definition, we suggest that the addition of "HIV infected with a CD4 count <100 cells/µL" to the EORTC host criteria be validated.

Dual Invasive Infection with Phaeoacremonium parasiticum and Paraconiothyrium cyclothyrioides in a Renal Transplant Recipient: Case Report and Comprehensive Review of the Literature of Phaeoacremonium Phaeohyphomycosis.

Despite increasing reports of human infection, data about the optimal care of Phaeoacremonium infections are missing. We report a case of an infection due to Phaeoacremonium parasiticum and Paraconiothyrium cyclothyrioides, initially localized to skin and soft tissue, in a kidney transplant patient. Despite surgical drainage and excision of the lesion and combination antifungal therapy with voriconazole and liposomal amphotericin B, a disseminated infection involving the lungs and brain developed and led to death. We performed a systematic literature review to assess the general features and outcome of human infections due to Phaeoacremonium species. Thirty-six articles were selected, and 42 patients, including ours, were reviewed. Thirty-one patients (74%) were immunocompromised because of organ or bone marrow transplantation (n = 17), diabetes or glucose intolerance (n = 10), rheumatoid arthritis or Still's disease (n = 4), chronic hematological diseases (n = 3), or chronic granulomatous disease (n = 3). Ten patients (24%) reported initial cutaneous trauma. Skin and soft tissue infections represented 57% of infections (n = 24), and disseminated infections, all occurring in immunocompromised patients, represented 14% of infections (n = 6). The main antifungal drugs used were azoles (n = 41) and amphotericin B (n = 16). Surgical excision or drainage was performed in 64% of cases (n = 27). The cure rate was 67% (n = 28). There were 10% cases of treatment failure or partial response (n = 4), 19% relapses (n = 8), and 7% losses to follow-up (n = 3). The death rate was 19% (n = 8). Management of Phaeoacremonium infections is complex because of slow laboratory identification and limited clinical data, and treatment relies on a combination of surgery and systemic antifungal therapy.

Serum Aspergillus galactomannan for the management of disseminated histoplasmosis in AIDS.

Disseminated histoplasmosis is an emerging infection in patients with cellular immune deficiency in non-endemic countries, caused by the migration from endemic regions and the development of travels. Diagnosis can be challenging in this context because rapid diagnostic tools such as Histoplasma antigen detection or appropriate molecular tools are generally unavailable, serology is often negative in immunosuppressed patients, and isolation of the fungus from cultures often takes several weeks. Here, we report the contribution of galactomannan serum detection for the management of an HIV-infected patient with disseminated histoplasmosis.
