HIV-associated talaromycosis: does timing of antiretroviral therapy matter༟. J Infect 2021; 84:410-417. [PMID: 34963636 DOI: 10.1016/j.jinf.2021.12.032] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Revised: 12/13/2021] [Accepted: 12/22/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVES No current academic data is available with respect to the optimal timing to initiate antiretroviral therapy (ART) in HIV-positive patients with talaromycosis. Our study aimed to evaluate the optimal timing of ART initiation for patients presenting with AIDS-related talaromycosis. METHODS In this prospective, randomized, open-label multicenter trial, 228 patients from 15 hospitals in China were randomly assigned to an early ART group (initiation of ART within 2 weeks after randomization) and a deferred ART group (initiation of ART 2 weeks after randomization). The primary endpoint was all-cause mortality during the 48 weeks after randomization. RESULTS We observed a significant difference in mortality between the early ART group and the deferred ART group (2.2% vs. 8.9%, 95%CI: -0.15 to 14.05, p=0.049). The composite outcome of AIDS-defining events or death in the early ART group was found to be lower than that in the deferred ART group (3.3% vs. 14.9%; 95%CI: 2.93 to 19.23, p=0.008). CONCLUSIONS The prognosis of HIV-infected patients with talaromycosis in the early ART group was more favorable than that of patients in the deferred ART group. These results demonstrate that early ART initiation should be considered in HIV-infected patients with talaromycosis .

Cutaneous manifestations and dermoscopic findings are important clues to the diagnosis of Talaromyces marneffei in HIV patients with immune reconstitution inflammatory syndrome: A case report and literature review. J Dermatol 2021; 49:168-172. [PMID: 34651702 DOI: 10.1111/1346-8138.16197] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Revised: 09/28/2021] [Accepted: 10/01/2021] [Indexed: 11/29/2022]
Abstract
Talaromyces (formerly Penicillium) marneffei is a dimorphic fungus that causes talaromycosis (formerly penicilliosis). The condition is predominantly found in patients with HIV. Important diagnostic clues are a history of living or travelling in endemic areas, and central umbilicated skin lesions. Dermoscopy is particularly useful for providing rapid bedside information, with a round, whitish, amorphous structure being the most common finding. Immune reconstitution inflammatory syndrome (IRIS) may occur. Driven by the initiation of antiretroviral therapy, IRIS is an exaggerated response of T cells to pathogens. Although mycobacterial and cryptococcal opportunistic infections are common with IRIS, a linkage between T. marneffei and IRIS has rarely been reported. Here, we report on a literature review of patients with HIV who developed IRIS associated with talaromycosis. Dermatologists should be aware of the cutaneous and dermoscopic findings of talaromycosis as they provide important clues that enable its early diagnosis and treatment.

Abstract
Talaromyces marneffei causes fatal invasive mycosis in Southeast Asia. Diagnosis by culture has limited sensitivity and can result in treatment delay. We describe the use of a novel Mp1p enzyme immunoassay (EIA) to identify blood culture-negative talaromycosis, subsequently confirmed by bone marrow cultures. This EIA has the potential to speed diagnosis, enabling early therapy initiation.

Abstract
Immune deficiency of diverse etiology, including human immunodeficiency virus (HIV), antineoplastic agents, immunosuppressive agents used in solid organ recipients, immunomodulatory therapy, and other biologics, all promote invasive fungal infections. Subsequent voluntary or unintended immune recovery may induce an exaggerated inflammatory response defining immune reconstitution inflammatory syndrome (IRIS), which causes significant mortality and morbidity. Fungal-associated IRIS raises several diagnostic and management issues. Mostly studied with Cryptococcus, it has also been described with other major fungi implicated in human invasive fungal infections, such as Pneumocystis, Aspergillus, Candida, and Histoplasma. Furthermore, the understanding of IRIS pathogenesis remains in its infancy. This review summarizes current knowledge regarding the clinical characteristics of IRIS depending on fungal species and existing strategies to predict, prevent, and treat IRIS in this patient population, and tries to propose a common immunological background to fungal IRIS.

Abstract
AbstractTalaromyces marneffei infection is increasingly observed in people living with human immunodeficiency virus (HIV) in eastern China, a nonendemic area. This study aimed to draw the clinician's attention to this disease by presenting the clinical characteristics and prognosis of penicilliosis among HIV-infected patients from this region. We retrospectively analyzed HIV-infected patients with culture-proven T. marneffei infection admitted during January 1, 2014-December 31, 2015, at the Shanghai Public Health Clinical Center. A total of 48 patients with confirmed HIV infection and penicilliosis were enrolled, which accounted for a mean of 3.2% (95% confidence interval: 2.4-4.2%) of yearly HIV infection admissions among patients from eastern China. Symptoms included fever, cough, and gastrointestinal complaints, whereas the most common sign was skin lesions. Anemia occurred in 87.5% (42/48) of the patients. The overall mortality rate was 16.7%. Low CD4 T-cell count and hemoglobin level were correlated with mortality. Based on these results, we concluded that penicilliosis should be considered in HIV-infected patients from eastern China who present with fever, cutaneous lesions, and anemia. The clinical characters and the prognosis of patients with penicilliosis are similar to those in endemic areas. More attention should be paid to penicilliosis patients with low CD4 T-cell count and/or low hemoglobin level.

Abstract
Invasive fungal infections (IFIs) are a major cause of HIV-related mortality globally. Despite widespread rollout of combined antiretroviral therapy, there are still up to 1 million deaths annually from IFIs, accounting for 50% of all AIDS-related death. A historic failure to focus efforts on the IFIs that kill so many HIV patients has led to fundamental flaws in the management of advanced HIV infection. This review, based on the EMBO AIDS-Related Mycoses Workshop in Cape Town in July 2013, summarizes the current state of the-art in AIDS-related mycoses, and the key action points required to improve outcomes from these devastating infections.

Abstract
Background Infection with Penicillium marneffei is a common opportunistic infection in Southeast Asia where it is endemic. We report a case of Penicillium marneffei infection with fatal outcome in a Togolese woman infected with Human Immunodeficiency Virus (HIV). Case presentation A 45-years-old patient, infected with Human Immunodeficiency Virus had consulted for ongoing febrile pneumonia since two weeks. Clinical examination revealed fever of 38.5°C, dyspnea, pulmonary syndrome condensation and papulo-nodular of “molluscum contagiosum” like lesions located on the face, arms, neck and trunk. Sputum smear was negative for tuberculosis. The chest radiograph showed reticulonodular opacities in the right upper and middle lobes and two caves in the right hilar region. The CD4 count was 6 cells/mm3 after a year of antiretroviral treatment (Zidovudine-Lamivudine-Efavirenz). She was treated as smear negative pulmonary tuberculosis after a lack of gentamicin and amoxicillin plus clavulanic acid response. Culture of skin samples and sputum had revealed the presence of P. marneffei. A treatment with ketoconazole 600 mg per day was initiated. After two weeks of treatment, there was a decrease in the size and number of papules and nodules, without any new lesions. We noted disappearance of cough and fever. The chest X-ray showed a decrease of pulmonary lesions. There was no reactivation of P. marneffei infection but the patient died from AIDS after two years of follow up. Conclusion We report a case of P. marneffei infection in a HIV-infected patient in a non-endemic country. Clinicians should think of P. marneffei infection in all HIV-infected patients with “molluscum contagiosum” like lesions.

Abstract
A 62-year-old British man with advanced HIV was established on antiretroviral therapy and treatment for disseminated Mycobacterium avium complex and Cytomegalovirus infections. One month later he re-presented with epigastric pain, an epigastric mass and skin lesions. Abdominal imaging revealed large volume lymphadenopathy, which was not present on previous imaging. Blood cultures yielded Penicillium marneffei, a dimorphic fungus endemic to South-east Asia. The patient had spent several years travelling in Thailand prior to the diagnosis of HIV. Penicilliosis is a common AIDS-defining illness in endemic areas, but remains rare in Europe. In this case, it presented in the context of a rapidly decreasing viral load as an immune reconstitution inflammatory syndrome. The challenges of management in the context of multiple comorbidities and polypharmacy are discussed.

Abstract
OBJECTIVE This study reports the clinical characteristics and outcome of HIV-associated Penicilliummarneffei infection in northern Vietnam. METHODS We conducted a retrospective chart review of all patients with laboratory confirmed Penicilliummarneffei infection admitted to the National Hospital for Tropical Diseases in Hanoi, Vietnam, between July 2006 and September 2009. RESULTS 127 patients with P. marneffei infection were identified. All were HIV-infected; median CD4+ T-cell count was 24 cells/μl (IQR:12-48); 76% were men. Common clinical features were fever (92.9%), skin lesions (82.6%), hepatomegaly (61.4%), lymphadenopathy (40.2%), weight loss (59.1%) and cough (49.6%). Concurrent opportunistic infections were present in 22.0%; half of those had tuberculosis. Initial treatment regimens were: itraconazole or ketoconazole capsule (77.2%), amphotericin B (20.5%), and fluconazole (1.6%). In-hospital mortality was 12.6% and showed no significant difference in patients treated with itraconazole (or ketoconazole) and amphotericin B (p = 0.43). Dyspnea, ascites, and increased LDH level were independent predictors of mortality. No seasonality was observed. CONCLUSION The clinical features, treatments and outcomes of HIV-associated P. marneffei infection in northern Vietnam are similar to those reported in other endemic regions. Dyspnea was an important predictor of mortality. More patients were treated with itraconazole than amphotericin B and no significant difference in treatment outcome was observed. It would be of clinical value to compare the efficacy of oral itraconazole and amphotericin B in a clinical trial.

Abstract
Backgrounds Disseminated Penicillium marneffei infection is one of the most common HIV-related opportunistic infections in Southeast Asia. Immune reconstitution inflammatory syndrome (IRIS) is a complication related to antiretroviral therapy (ART)-induced immune restoration. The aim of this report is to present a case of HIV-infected child who developed an unmasking type of IRIS caused by disseminated P. marneffei infection after ART initiation. Case presentation A 14-year-old Thai HIV-infected girl presented with high-grade fever, multiple painful ulcerated oral lesions, generalized non-pruritic erythrematous skin papules and nodules with central umbilication, and multiple swollen, warm, and tender joints 8 weeks after ART initiation. At that time, her CD4+ cell count was 7.2% or 39 cells/mm3. On admission, her repeated CD4+ cell count was 11% or 51 cells/mm3 and her plasma HIV-RNA level was < 50 copies/mL. Her skin biopsy showed necrotizing histiocytic granuloma formation with neutrophilic infiltration in the upper and reticular dermis. Tissue sections stained with hematoxylin and eosin (H&E), periodic acid-Schiff (PAS), and Grocott methenamine silver (GMS) stain revealed numerous intracellular and extracellular, round to oval, elongated, thin-walled yeast cells with central septation. The hemoculture, bone marrow culture, and skin culture revealed no growth of fungus or bacteria. Our patient responded well to intravenous amphotericin B followed by oral itraconazole. She fully recovered after 4-month antifungal treatment without evidence of recurrence of disease. Conclusions IRIS from P. marneffei in HIV-infected people is rare. Appropriate recognition and properly treatment is important for a good prognosis.

Penicillium marneffei-stimulated dendritic cells enhance HIV-1 trans-infection and promote viral infection by activating primary CD4+ T cells. PLoS One 2011; 6:e27609.

Abstract
Penicillium marneffei (P. marneffei) is considered an indicator pathogen of AIDS, and the endemicity and clinical features of P. marneffei have been described. While, how the co-infection of P. marneffei exacerbate deterioration of the immune response remains poorly understood. Here we isolated P. marneffei from the cutaneous lesions of AIDS patients and analyzed its effects on HIV-1-dendritic cells (DCs) interaction. We demonstrated that the monocyte-derived dendritic cells (MDDCs) could be activated by both thermally dimorphic forms of P. marneffei for significantly promoting HIV-1 trans-infection of CD4+ T cells, while these activated MDDCs were refractory to HIV-1 infection. Mechanistically, P. marneffei-activated MDDCs endocytosed large amounts of HIV-1 and sequestrated the internalized viruses into tetrapasnin CD81+ compartments potentially for proteolysis escaping. The activated MDDCs increased expression of intercellular adhesion molecule 1 and facilitated the formation of DC-T-cell conjunctions, where much more viruses were recruited. Moreover, we found that P. marneffei-stimulated MDDCs efficiently activated resting CD4+ T cells and induced more susceptible targets for viral infection. Our findings demonstrate that DC function and its interaction with HIV-1 have been modulated by opportunistic pathogens such as P. marneffei for viral dissemination and infection amplification, highlighting the importance of understanding DC-HIV-1 interaction for viral immunopathogenesis elucidation.
