Pan L, Shao H. Ultrasound characterization of superficial lymph nodes in HIV patients with Talaromyces marneffei infection. Front Med (Lausanne) 2023; 10:1243599. [PMID: 38148912 PMCID: PMC10750475 DOI: 10.3389/fmed.2023.1243599] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Accepted: 11/10/2023] [Indexed: 12/28/2023] Open
Abstract
Objectives This study aimed at exploring the ultrasound characteristics of superficial lymph nodes (LNs) in HIV patients with Talaromyces marneffei infection to provide assistance and understanding for diagnosis and therapy. Methods A retrospective analysis was conducted on 26 patients with confirmed HIV and T.marneffei coinfection. These patients underwent ultrasound examination and ultrasound-guided puncture biopsies at our hospital from March 2015 to March 2023. Results In all 26 patients, lymphadenectasis was observed. Among the 21 cases (80.76%), LNs showed a diffusely hyperechoic appearance with a tulle-like change, and 6 cases (23.07%) showed liquefaction. When the hila were present or thinned, the blood flow signals were primarily hilar, whether rich or poor, and when the hila were absent, the blood flow signals were peripheral or poor. The axillary LN long-to-short diameter (L/S) ratios exhibited a significant positive correlation with CD4+T cell counts (r = 0.8214, p = 0.0341). Patients with retroperitoneal lymphadenectasis showed decreased NK cell counts (p = 0.03). Conclusion In summary, the T.marneffei infection of LNs in HIV patients often manifests with superficial LN enlargement, mostly affecting the cervical LNs. The T.marneffei-infected LNs exhibit several characteristics such as echogenicity, hilum, and blood flow signal. Furthermore, there might be associations between lymphocyte subsets and enlarged superficial LNs. Ultrasound examinations should be paid attention to if patients have superficial LN enlargement, and the diagnosis of the T.marneffei infection is considered.

Abstract
Disseminated ankle mycosis is a life-threatening systemic infection caused by the emerging opportunistic and lethal fungal pathogen Talaromyces marneffei which is more common in HIV-positive patients. However, an increasing number of infections are occurring in HIV-negative patients. Here, we report a case of Talaromyces marneffei infection in HIV-negative patient. A 50s HIV-negative male patient with fever, cough, bloody sputum expectoration, pulmonary sarcoidosis and body rashes was hospitalized at Zhejiang Provincial People's Hospital. CT scanning showed pulmonary multiple nodules with apical bronchial occlusion, patchy infiltration and pathological biopsy demonstrated bronchiolitis obliterans with organized pneumonia and chronic active inflammation of lung tissue with infiltration of numerous lymphocytes, plasma cells, phagocytes and neutrophils. Laboratory tests revealed significantly increased white blood cells count 18.3 ×109/L, neutrophil count 15.34 ×109/L, monocyte count 0.66 ×109/L, platelet count 517 ×109/L, C-reactive protein 116 mg/L, erythrocyte sedimentation rate 112mm/h. The β-D-glucan test was negative (33.06 pg/mL) while fungal culture of broncho alveolar lavage fluid revealed colonies with temperature-dependent dimorphic growth character and Talaromyces marneffei was confirmed by ITS sequencing of the colonies. The patient exhibited radiological improvement and clinical recuperation after intravenously guttae of voriconazole. Talaromycosis in immunocompetent and HIV-negative individuals is relatively rare and is characterized by an insidious onset, various clinical manifestations, and is clinically challenging. Fungal culture and ITS sequencing are warranted for diagnosis Talaromyces marneffei infection. This is the first report on identification of Talaromyces marneffei infection in an HIV-negative patient with skin involvement by ITS sequencing in Zhejiang.

Abstract
INTRODUCTION Talaromyces marneffei (T. marneffei), a dimorphic fungus, causes local or disseminated infection in humans. We aimed to analyze the clinical characteristics, prognostic factors, and survival outcomes of patients with T. marneffei infection and compare the differences between human immunodeficiency virus (HIV)-positive and HIV-negative subgroups. METHODS We retrospectively analyzed 241 patients with T. marneffei infection at the First Affiliated Hospital of Guangxi Medical University between January 2012 and January 2022. The overall population was stratified into HIV-positive (n = 98) and HIV-negative (n = 143) groups according to HIV status. Kaplan-Meier analysis and multivariate Cox regression models were used to determine the prognostic factors for overall survival (OS) and progression-free survival (PFS). RESULTS With a median follow-up time of 58.9 months, 120 patients (49.8%) experienced disease progression and 85 patients (70.8%) died. The 5-year rates of OS and PFS were 61.4% (95% CI 55.0-68.6%) and 47.8% (95% CI 41.5-55.1%), respectively. As an independent factor, patients who were HIV positive had better PFS (HR 0.50, 95% CI 0.31-0.82; p < 0.01) than patients who were HIV negative. Compared with patients who were HIV positive, patients who were HIV negative were older and had more probabilities of underlying diseases, chest involvement, bone destruction, and higher count of neutrophils (all p < 0.05). Hemoglobin (PFS: HR 0.62; 95% CI 0.39-1.00; p < 0.05; OS: HR 0.45; 95% CI 0.22-0.89; p = 0.02) and lymphocyte count (PFS: HR 0.06; 95% CI 0.01-0.26; p < 0.01; OS: HR 0.08; 95% CI 0.01-0.40; p < 0.01) were independent prognostic factors for PFS and OS in patients who were HIV negative. CONCLUSIONS Patients with T. marneffei infection have a poor prognosis. Patients who are HIV positive and HIV negative have relatively independent clinical characteristics. Multiple organ involvement and disease progression are more common in patients who are HIV negative.

Abstract
BACKGROUND Talaromyces marneffei, formerly known as Penicillium marneffei, is a significant emerging pathogenic fungus in Southeast Asia which can generate life-threatening systemic infections. Human immunodeficiency virus (HIV) infection is considered as the most underlying disease among systemic infections. However, infections due to T. marneffei without HIV are increasing in recent years. OBJECTIVES Research the characteristics of T. marneffei infection in non-HIV individuals in mainland China. METHODS In this study, we searched Pubmed, China National Knowledge Infrastructure (CNKI) and WanFang from inception to 31 December 2019 for studies reporting T. marneffei infection. Our research concentrates on non-HIV-infected cases and their epidemiology, clinical manifestations, laboratory findings, treatment methods and prognosis. RESULTS T. marneffei infections in non-HIV individuals are increasing. Due to frequent present with atypical symptoms, these non-HIV-infected cases were usually misdiagnosed as other diseases, containing tuberculosis (80.7%), bacterial pneumonia (20.5%), lung cancer (5.1%) or other diseases (5.1%). CONCLUSIONS T. marneffei infection in non-HIV individuals should be taken seriously. Their symptoms and signs are not typical. Accurate diagnosis and timely antifungal agent treatment is the key to the treatment for the disease.

Potential effects of microbial air quality on the number of new cases of diabetes type 1 in children in two regions of Poland: a pilot study. Infect Drug Resist 2019; 12:2323-2334. [PMID: 31534351 PMCID: PMC6681153 DOI: 10.2147/idr.s207138] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2019] [Accepted: 06/12/2019] [Indexed: 12/15/2022] Open
Abstract
Aim: The aim of the study was to investigate the relationship between the concentration of psychrophilic bacteria, mesophilic bacteria and mold fungi in bioaerosols, and the number of new cases of type 1 diabetes mellitus (T1DM) in children. Methods: Air samples from the Lubelskie and Pomeranian voivodeships in Poland were collected from January 2015 to December 2016 in winter, spring, summer and autumn. Thirty-three samples were collected in the Pomeranian and 27 in the Lubelskie voivodeship. The air samples were collected on the first day of each month at 1:00 pm for 10 mins at a height of 1.5 m above the ground. The number of mesophilic bacteria was detected after 24-48 hrs incubation at 37°C on tryptone soya agar (TSA; Merck, Darmstadt, Germany). The number of psychrophilic bacteria was detected after 72 hrs incubation at 22°C on TSA. The number of fungi was detected by a 5-day long incubation at 28°C on chloramphenicol yeast glucose agar. Results: In the Lubelskie voivodeship, the mean concentration of psychrophilic bacteria was significantly higher than in the Pomeranian voivodeship (2739 vs 608 CFU/m3, respectively), the mean concentration of mesophilic bacteria was significantly higher (2493 vs 778/m3, respectively) and the concentration of fungi was significantly higher (3840 vs 688 CFU/m3, respectively). We also showed a statistically significant relationship between the number of children with recently diagnosed T1DM and the mean concentration of psychrophilic and mesophilic bacteria in the Pomeranian and Lubelskie voivodeships (P<0.001). Moreover, we found a significant relationship between the number of new cases of T1DM in children and the mean concentration of fungi in bioaerosols in the Lubelskie voivodeship (P<0.001), but not in the Pomeranian voivodeship (P=NS). Conclusion: The results of our research showed that there is a higher concentration of microbial particles in the Lublin voivodeship. Therefore, we recommend changes in climate for children (trips to the sea, mountains, etc) as often as possible.

Abstract
Penicillium marneffei infection in human immunodeficiency virus (HIV)-negative patients is addressed far less often. In this article, a small cohort of HIV-negative patients who disseminated P. marneffei infection was included. Sites of infection were found from blood culture, as subcutaneous nodules, or from lymph node biopsy. Fever, rash, swollen lymph nodes, anaemia and weight loss were common characteristics in most infected patients. The signs and symptoms are diverse and create challenges for accurate diagnosis. This paper will assist our understanding of this disease and contribute to an appropriate regime of therapy, thus improving the health of P. marneffei-positive patients.

Abstract
Penicilliosis infection caused by Penicillium marneffei is the third most common opportunistic infection in Human Immunodeficiency Virus patients in South-east Asia; however, Penicillium infection caused by non- P. marneffei is uncommon. We present a case of an immunocompetent male with disseminated penicilliosis (non- P. marneffei) presenting with recurrent empyema. The case described illustrates the challenges in managing a complicated systemic infection and the outcomes of a delayed presentation, in a potentially treatable disease.

Abstract
The Penicillium genera, encompassing about 225 different species of fungi, are naturally present in the environment. These genera are poorly linked to human disease, except for Penicillium marneffei causing septicemia in immunocompromised hosts. Thus, Penicillium species recovered from respiratory tract samples are often considered as inhaled contaminants in the clinical laboratory. However, we report here a case of fungal maxillary sinusitis due to Penicillium roqueforti diagnosed in a 40-year-old female, a teacher, complaining of moderate pain for months in the maxillary sinus and chronic posterior rhinorrhea. CT scanner and MRI enabled a preliminary diagnosis of left maxillary fungus ball-type sinusitis with calcified material seen on CT and marked very low signal in T2 weighted images seen on MRI. Anatomopathological and mycological examination of sinusal content showed septate hyphae. Direct sequencing of the sinusal content revealed P. roqueforti. P. roqueforti has been traditionally used in France for more than 200 years for cheese ripening. However, to our knowledge, this ascomycetous fungus has very rarely been associated in the literature with human disease. P. roqueforti is associated only with cheese worker's lung, a hypersensitivity pneumonitis affecting employees in blue cheese factories. Other species in the Penicillium genus are reported to cause various disorders such as invasive infection, superficial infection or allergic diseases. P. roqueforti has never previously been reported as a cause of human infection. Thus, we report the first case of fungus ball due to P. roqueforti in an immunocompetent patient.

Abstract
Penicillium capsulatum is a rare Penicillium species used in paper manufacturing, but recently it has been reported to cause invasive infection. To research the pathogenicity of the clinical Penicillium strain, we sequenced the genomes and transcriptomes of the clinical and environmental strains of P. capsulatum. Comparative analyses of these two P. capsulatum strains and close related strains belonging to Eurotiales were performed. The assembled genome sizes of P. capsulatum are approximately 34.4 Mbp in length and encode 11,080 predicted genes. The different isolates of P. capsulatum are highly similar, with the exception of several unique genes, INDELs or SNPs in the genes coding for glycosyl hydrolases, amino acid transporters and circumsporozoite protein. A phylogenomic analysis was performed based on the whole genome data of 38 strains belonging to Eurotiales. By comparing the whole genome sequences and the virulence-related genes from 20 important related species, including fungal pathogens and non-human pathogens belonging to Eurotiales, we found meaningful pathogenicity characteristics between P. capsulatum and its closely related species. Our research indicated that P. capsulatum may be a neglected opportunistic pathogen. This study is beneficial for mycologists, geneticists and epidemiologists to achieve a deeper understanding of the genetic basis of the role of P. capsulatum as a newly reported fungal pathogen.

Abstract
We herein report a case of Penicillium marneffei infection (PMI) in a Japanese man who was infected with human immunodeficiency virus-1 (HIV-1), who was diagnosed on the basis of a bone marrow culture and who was effectively treated with itraconazole. Our review of the PMI cases reported in Japan suggests that increased serum (1→3)-β-D-glucan levels are a useful diagnostic tool in cases of suspected PMI.
