Disseminated Mycoplasma fermentans in AIDS patients: several case reports

Area of Science:

• Infectious Diseases
• HIV/AIDS Research
• Microbiology

Background:

• Human Immunodeficiency Virus (HIV) positive individuals are susceptible to opportunistic infections.
• Mycoplasma fermentans is a bacterium that can cause various infections.
• Disseminated and persistent infections pose significant clinical challenges.

Observation:

• Two HIV-positive patients presented with recurrent lower respiratory tract infections and fever.
• Mycoplasma fermentans was persistently detected in peripheral blood mononuclear cells (PBMC), bronchoalveolar lavage (BAL), liver, bone marrow, and respiratory tract tissues over extended periods (18-27 months).
• One patient had M. fermentans-positive granulomas in the liver without other opportunistic infections.

Findings:

• Mycoplasma fermentans was identified as a disseminated and persistent pathogen in both HIV-positive patients.
• The bacterium was detected in multiple tissue types, including blood, respiratory, liver, and bone marrow specimens.
• Evidence suggests M. fermentans may have played a role in the respiratory disease of one patient and systemic illness of the other.

Implications:

• This case study underscores the potential for Mycoplasma fermentans to cause persistent and disseminated infections in immunocompromised individuals.
• The findings suggest a need for increased awareness and diagnostic consideration of M. fermentans in HIV-positive patients with complex or refractory illnesses.
• Further research is warranted to elucidate the pathogenesis and treatment strategies for Mycoplasma fermentans in the context of HIV.
