A case of loiasis in Rome
1Istituto Dermatologico S. Gallicano (IRCCS), Servizio di Medicina Preventiva delle Migrazioni, del Turismo e di Dermatologia Tropicale, Rome, Italy.
Summary
Loa loa infestation, a tropical filariasis, can present with non-specific symptoms like severe itchy skin in immigrants. Early diagnosis of loiasis is crucial for effective treatment.
Area of Science:
- Tropical medicine
- Parasitology
- Dermatology
Background:
- Increased global travel and migration facilitate the introduction of tropical diseases into non-endemic regions.
- Loiasis, a filarial disease caused by Loa loa and transmitted by Chrysops flies, is increasingly observed in immigrant populations.
- Dermatological manifestations of tropical diseases can be non-specific and challenging to diagnose.
Observation:
- A case of Loa loa infestation (loiasis) is presented in a male immigrant from Cameroon.
- The patient exhibited severe xerosis (dry skin) and intense pruritus (itching) on the lower legs, with excoriations from scratching.
- Topical emollients, anti-acarus treatments, and systemic antihistamines provided no relief.
Findings:
- Microfilariae of Loa loa were identified in serum samples using Giemsa and other stains.
- A definitive diagnosis of Loa loa infestation (loiasis) was established.
Implications:
- Highlights the importance of considering tropical diseases in patients with unexplained dermatological symptoms, especially those with a history of travel or migration.
- Challenges the "Salgari's syndrome" approach of over-diagnosing tropical diseases and emphasizes accurate diagnosis over assumptions.
- Underscores the need for increased awareness among physicians, particularly dermatologists, regarding the presentation of neglected tropical diseases in diverse patient populations.
