Talaromyces marneffei infection in non-HIV-infected patients in mainland China.

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.
