Insights

This study reports a rare case of disseminated Penicillium marneffei infection in an HIV-negative woman, presenting with osteolytic lesions. The findings highlight distinct clinical features compared to infections in HIV-positive individuals.

Area of Science:

  • Mycology
  • Infectious Diseases
  • Clinical Case Study

Background:

  • Penicillium marneffei is a thermally dimorphic fungus endemic to Southeast Asia.
  • It typically causes disseminated infections in individuals with Human Immunodeficiency Virus (HIV).
  • Infection in HIV-negative individuals is exceptionally rare.

Observation:

  • A 40-year-old HIV-negative woman presented with fever, lymphadenopathy, and rash.
  • Diagnosis confirmed disseminated Penicillium marneffei infection via sternum biopsy.
  • Bone scan revealed osteolytic lesions in the clavicle and sternum.

Findings:

  • The patient's presentation and osteolytic lesion development are detailed.
  • Clinical manifestations in this HIV-negative patient are compared to those in HIV-positive cases.
  • This case underscores the potential for P. marneffei to cause severe disease in non-immunocompromised individuals.

Implications:

  • This case expands the understanding of Penicillium marneffei epidemiology and clinical spectrum.
  • It emphasizes the need for considering P. marneffei in endemic areas, even in HIV-negative patients with unusual presentations.
  • Highlights potential differences in disease presentation and management strategies between HIV-positive and HIV-negative patients.

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Pneumonia I: Introduction01:29

Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...

Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
