Strongyloides stercoralis (SSM) is a parasitic roundworm that infects over 100 million people worldwide. It is typically found in tropical and subtropical regions, particularly in areas with poor sanitation and hygiene. Strongyloides stercoralis hyperinfection syndrome (SSM-HS) is a life-threatening condition that can occur in people with weakened immune systems.
Uncomplicated SSMID:
SSM-HS:
SSM is transmitted through contact with contaminated soil or water. The larvae penetrate the skin and migrate through the blood to the lungs. In the lungs, they develop into adults and produce eggs that are coughed up and swallowed. The eggs hatch in the intestines and release larvae that can either re-infect the same person (autoinfection) or be passed in the stool to infect others.
SSM can be diagnosed through a variety of laboratory tests, including:
SSM is treated with antiparasitic medications such as:
In cases of SSM-HS, more aggressive treatment may be necessary, including:
Early diagnosis and treatment of SSM is crucial to prevent the development of SSM-HS. Without proper treatment, SSM can lead to severe complications, including death.
Treatment of SSM can:
Table 1: Symptoms of SSMID
Symptom | Uncomplicated SSMID | SSM-HS |
---|---|---|
Abdominal pain | Mild | Severe |
Diarrhea | Loose stools | Severe gastrointestinal distress |
Nausea and vomiting | Yes | Yes |
Fatigue | Yes | Yes |
Skin irritation | Larva currens | Abscesses and boils |
Table 2: Risk Factors for Developing SSM-HS
Risk Factor | Description |
---|---|
Immunodeficiency | HIV/AIDS, organ transplant, cancer treatment |
Long-term corticosteroid use | Suppresses immune system |
Chronic diseases | Diabetes, liver cirrhosis |
Malnutrition | Impairs immune response |

A: Treatment typically lasts for 2-3 weeks.
Q: Can SSM recur after treatment?
A: Yes, SSM can recur in people with weakened immune systems.
Q: How can I prevent SSM?
A: Practice good hygiene, wear shoes in endemic areas, and avoid contact with contaminated water or soil.
Q: Is SSM contagious?
A: Yes, SSM is contagious and can be transmitted from person to person.
Q: What is the mortality rate of SSM-HS?
