Giardiasis: Characteristics, Pathogenesis and New Insights About Treatment

Area of Science:

• Gastroenterology
• Infectious Diseases
• Pharmacology

Background:

• Giardia intestinalis infection leads to enterocyte damage, brush border loss, and impaired epithelial barrier function.
• Clinical manifestations include diarrhea, steatorrhea, nausea, abdominal pain, and nutrient malabsorption.
• While effective drugs exist, suboptimal dosing, emerging resistance, and side effects impact treatment efficacy and patient adherence.

Purpose of the Study:

• To review current drugs used for Giardia treatment, including their mechanisms of action, efficacy, dosing, and side effects.
• To explore novel therapeutic strategies for Giardia infections, such as phytochemicals, Lactobacillus, and nanotechnology.
• To identify an ideal treatment for Giardia with maximum efficacy and minimal adverse effects.

Main Methods:

• Literature review of existing drugs for Giardia treatment.
• Inclusion of in vitro and clinical studies on drug efficacy and side effects.
• Compilation of emerging therapies including phytochemicals, probiotics, and nanotechnology.

Main Results:

• Current Giardia treatments have varying efficacy, with concerns regarding suboptimal dosing and resistance.
• Drug side effects can lead to poor patient adherence.
• Emerging therapies show promise for improved efficacy and reduced adverse effects.

Conclusions:

• There is a need for optimized treatment strategies for Giardia intestinalis infections.
• Novel approaches like phytochemicals, Lactobacillus, and nanotechnology offer potential for more effective and safer treatments.
• Further research is warranted to establish ideal therapeutic regimens for Giardia.
