Leishmaniasis: diagnostic issues in Europe

Area of Science:

• Medical Parasitology
• Infectious Diseases
• Clinical Diagnostics

Background:

• Leishmaniasis presents diverse clinical forms, from asymptomatic to severe cutaneous, mucocutaneous, and visceral disease.
• European prevalence is rising due to increased travel, challenges in treating AIDS patients, and immunosuppressive therapies.
• Clinical diagnosis is difficult, and traditional parasitological methods can be invasive and yield inconclusive results in immunosuppressed patients.

Purpose of the Study:

• To review the diagnostic challenges of leishmaniasis.
• To highlight advancements in diagnostic methodologies.
• To emphasize the impact of new techniques on patient management.

Main Methods:

• Review of epidemiological trends and diagnostic approaches for leishmaniasis.
• Evaluation of serological and antigen detection tests, noting variable sensitivity and specificity.
• Assessment of polymerase chain reaction (PCR) as a molecular diagnostic tool.

Main Results:

• Current diagnostic methods for leishmaniasis have limitations, particularly in immunocompromised individuals.
• Serological and antigen tests show variable performance depending on the Leishmania species.
• Polymerase chain reaction (PCR) assays demonstrate improved sensitivity and specificity for detecting leishmanial genetic material.

Conclusions:

• Accurate diagnosis of leishmaniasis remains a clinical challenge.
• Polymerase chain reaction (PCR) represents a significant improvement in diagnosing leishmaniasis and assessing treatment efficacy.
• Further development and standardization of molecular diagnostic tools are crucial for effective leishmaniasis control.
