Heliyon 2024; 10:e34024. [PMID: 39055798 PMCID: PMC11269883 DOI: 10.1016/j.heliyon.2024.e34024] [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: 01/30/2024] [Revised: 06/26/2024] [Accepted: 07/02/2024] [Indexed: 07/28/2024] Open
Abstract
Objectives This case-control study aimed to analyze the characteristics and risk factors for death in HIV-positive Talaromycosis marneffei (TSM) patients with sepsis. Methods We retrospectively reviewed 173 AIDS patients diagnosed with TSM infection from January 1, 2013, to December 1, 2023, at Hangzhou Xixi Hospital. We collected and analyzed clinical characteristics, laboratory findings, bone marrow cytology results, treatment, and prognosis. Results Out of 173 AIDS-TSM patients, 92 had sepsis while 81 did not. AIDS-TSM patients with sepsis have a higher in-hospital mortality rate (19.6 %) than non-sepsis patients (0 %). The SOFA score showed a significant association with in-hospital mortality in AIDS-TSM patients with sepsis (OR = 1.583, 95 % CI: 1.183-2.118, P = 0.002), indicating an almost linear relationship. After adjusting for the SOFA score, only hemoglobin (Hb) (OR = 0.971, 95 % CI: 0.943-1.000, P = 0.046), international normalized ratio (INR) (OR = 22.33, 95 % CI: 1.84-270.90, P = 0.015), and C-reactive protein (CRP) (OR = 1.014, 95 % CI: 1.001-1.027, P = 0.039) remained significantly associated with in-hospital mortality. The Receiver Operating Characteristic (ROC) curve of the SOFA score, INR, and CRP showed moderately good predictive performance for in-hospital mortality, while Hb had a low predictive performance. The Area Under Curve (AUC) values were 0.834, 0.820, 0.776, and 0.669, respectively. Conclusions AIDS-TSM patients with sepsis have a higher mortality rate. Moreover, the SOFA score, along with Hb, INR, and CRP, are the risk factors for death in AIDS-TSM patients with sepsis.

Yang S, Lou L, Ma S, Wang H, Rong L, Liu Y, Zhang K, Ai Q, Shi X. Disseminated Talaromyces marneffei infection initially presenting as cutaneous and subcutaneous lesion in an HIV-Negative renal transplant recipient: a case report and literature review. BMC Infect Dis 2024; 24:473. [PMID: 38711014 PMCID: PMC11071178 DOI: 10.1186/s12879-024-09351-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2023] [Accepted: 04/25/2024] [Indexed: 05/08/2024] Open
Abstract
BACKGROUND The incidence of Talaromyces marneffei (T. marneffei) infection has increased in recent years with the development of organ transplantation and the widespread use of immunosuppressive agents. However, the lack of clinical suspicion leading to delay or misdiagnosis is an important reason for the high mortality rate in non-human immunodeficiency virus (HIV) and non-endemic population. Herein, we report a case of disseminated T. marneffei infection in a non-HIV and non-endemic recipient after renal transplant, who initially presented with skin rashes and subcutaneous nodules and developed gastrointestinal bleeding. CASE PRESENTATION We describe a 54-year-old renal transplantation recipient presented with scattered rashes, subcutaneous nodules and ulcerations on the head, face, abdomen, and right upper limb. The HIV antibody test was negative. The patient had no obvious symptoms such as fever, cough, etc. Histopathological result of the skin lesion sites showed chronic suppurative inflammation with a large number of fungal spores. Subsequent fungal culture suggested T. marneffei infection. Amphotericin B deoxycholate was given for antifungal treatment, and there was no deterioration in the parameters of liver and kidney function. Unfortunately, the patient was soon diagnosed with gastrointestinal bleeding, gastrointestinal perforation and acute peritonitis. Then he rapidly developed multiple organ dysfunction syndrome and abandoned treatment. CONCLUSIONS The risk of fatal gastrointestinal bleeding can be significantly increased in kidney transplant patients with T. marneffei infection because of the long-term side effects of post-transplant medications. Strengthening clinical awareness and using mNGS or mass spectrometry technologies to improve the detection rate and early diagnosis of T. marneffei are crucial for clinical treatment in non-HIV and non-endemic population.

Abstract
PURPOSE OF REVIEW This review highlights the epidemiology, pathogenesis and clinical management of pulmonary infections caused by emerging fungal organisms. RECENT FINDINGS Emerging fungal infections have arisen as a result of population and environmental changes. An enlarging pool of immunocompromised hosts on triazole antifungal prophylaxis has led to an increased incidence of non- Aspergillus molds, such as Fusarium , Scedosporium and Lomentospora spp. Advances in diagnostic capabilities led to the identification of the Emergomyces genus and non- dermatitidis Blastomyces species, which have a significant disease burden in Africa and the Middle East. Climate change has contributed to changing the distribution of previously confined endemic mycoses, like coccidioidomycosis and talaromycosis. These emerging organisms pose important diagnostic and therapeutic challenges. SUMMARY Newly recognized pathogenic fungi and established endemic mycoses with expanding geographic boundaries have become important agents of pulmonary disease. There is a dearth of clinical evidence on the appropriate management of these infections.

Infect Drug Resist 2024; 17:1333-1343. [PMID: 38596535 PMCID: PMC11001556 DOI: 10.2147/idr.s451880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Accepted: 03/19/2024] [Indexed: 04/11/2024] Open
Abstract
Background Talaromyces marneffei (TM) is the third most prevalent opportunistic infection in HIV-positive patients after tuberculosis and cryptococcosis. However, such infection of non-HIV individuals has rarely been reported. Case Presentation We describe a very rare case of a 52-year-old male who presented with a single space-occupying lesion on the right lung and was eventually diagnosed with pulmonary TM infection. The patient was HIV-negative and had liver cirrhosis with portal vein thrombosis. Lung tissue next-generation sequencing (NGS) revealed TM infection. We successfully treated the patient with voriconazole for 8 weeks and observed lesion absorption via subsequent CT. The patient consumed wild bamboo rats two months before admission. Mutations related to congenital immune deficiency were not detected by whole-exome sequencing. Conclusion Early and timely diagnosis is critical for improving patient prognosis. NGS plays a vital role in the diagnosis of pulmonary TM infection in patients. To our knowledge, this is the first published case of pulmonary TM infection in an HIV-negative patient with liver cirrhosis.

Microbiota of long-term indwelling hemodialysis catheters during renal transplantation perioperative period: a cross-sectional metagenomic microbial community analysis. Ren Fail 2023; 45:2256421. [PMID: 37724520 PMCID: PMC10512886 DOI: 10.1080/0886022x.2023.2256421] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Accepted: 09/02/2023] [Indexed: 09/21/2023] Open
Abstract
Background: Catheter-related infection (CRI) is a major complication in patients undergoing hemodialysis. The lack of high-throughput research on catheter-related microbiota makes it difficult to predict the occurrence of CRI. Thus, this study aimed to delineate the microbial structure and diversity landscape of hemodialysis catheter tips among patients during the perioperative period of kidney transplantation (KTx) and provide insights into predicting the occurrence of CRI.Methods: Forty patients at the Department of Transplantation undergoing hemodialysis catheter removal were prospectively included. Samples, including catheter tip, catheter outlet skin swab, catheter blood, peripheral blood, oropharynx swab, and midstream urine, from the separate pre- and post-KTx groups were collected and analyzed using metagenomic next-generation sequencing (mNGS). All the catheter tips and blood samples were cultured conventionally.Results: The positive detection rates for bacteria using mNGS and traditional culture were 97.09% (200/206) and 2.65% (3/113), respectively. Low antibiotic-sensitivity biofilms with colonized bacteria were detected at the catheter tip. In asymptomatic patients, no statistically significant difference was observed in the catheter tip microbial composition and diversity between the pre- and post-KTx group. The catheter tip microbial composition and diversity were associated with fasting blood glucose levels. Microorganisms at the catheter tip most likely originated from catheter outlet skin and peripheral blood.Conclusions: The long-term colonization microbiota at the catheter tip is in a relatively stable state and is not readily influenced by KTx. It does not act as the source of infection in all CRIs, but could reflect hematogenous infection to some extent.
