Insights

Donor-derived Candida dubliniensis caused a rare chronic meningitis in a lung transplant recipient. Diagnosis was challenging due to low cerebrospinal fluid culture yield, highlighting the need for advanced fungal diagnostics.

Area of Science:

  • Infectious Diseases
  • Transplantation Medicine
  • Mycology

Background:

  • Candida species commonly colonize the oral and respiratory tracts of lung transplant recipients.
  • While often non-pathogenic, donor-derived Candida infections can occur, posing risks.
  • Chronic meningitis is a rare but severe manifestation of invasive candidiasis, difficult to diagnose.

Observation:

  • A lung transplant recipient developed empyema, successfully treated, followed by chronic meningitis.
  • The meningitis was suspected to be a possible donor-derived Candida dubliniensis infection.
  • Cerebrospinal fluid cultures yielded low results, delaying diagnosis.

Findings:

  • Diagnosis was confirmed using fungal PCR and Beta-D-glucan assay.
  • These advanced diagnostic methods proved crucial for identifying the fungal meningitis.
  • The case highlights a rare presentation of invasive candidiasis post-transplantation.

Implications:

  • Early diagnosis of invasive fungal infections in transplant recipients is critical.
  • Advanced diagnostics like fungal PCR and BD glucan assays are vital when cultures are negative.
  • This case underscores the potential for rare, severe donor-derived infections in immunocompromised patients.

Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Lung Capacity01:47

Lung Capacity

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Chronic Pharyngitis01:23

Chronic Pharyngitis

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Pleura of the Lungs01:13

Pleura of the Lungs

The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...

Tissue Transplantation01:24

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
The Biology of Tissue Transplantation
The biology of tissue transplantation hinges on the Major Histocompatibility Complex (MHC) molecules. These molecules...

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
