Abstract:
Fungic infections related to parenteral use of drugs increased significantly from 1980 on with the description of the disseminated candidiasis syndrome. Associated to the administration of brown heroin, this syndrome is characterized by the development of cutaneous, ocular and osteoarticular infections, isolated or combined, by Candidas albicans. We present 15 patients with disseminated candidiasis: 12 developed ocular affection (10 endophthalmitis and 2 chorioretinitis): 9, cutaneous lesions and 3 osteoarticular affection (3 costochondritis and one hip arthritis); 8 presented simultaneous infections in several locations. The biopsy and culture of the cutaneous lesions was the most profitable test in order to establish the microbiological diagnosis. We comment on the main etiopathogenetic, clinical, diagnostic and therapeutic aspects of the disseminated candidiasis syndrome.
Insights
Fungal infections, particularly disseminated candidiasis, linked to intravenous drug use have risen. This syndrome, often caused by Candida albicans, affects skin, eyes, and joints, with skin biopsy proving key for diagnosis.
Area of Science:
- Mycology
- Infectious Diseases
- Dermatology
Context:
- Parenteral drug use, particularly intravenous heroin, has been associated with a significant increase in fungal infections since the 1980s.
- The disseminated candidiasis syndrome, characterized by Candida albicans infections, presents a complex clinical challenge.
Purpose:
- To describe the clinical, diagnostic, and therapeutic aspects of disseminated candidiasis in parenteral drug users.
- To highlight the common manifestations and diagnostic utility of cutaneous lesions in this patient population.
Summary:
- Fifteen patients with disseminated candidiasis were analyzed, exhibiting diverse infections including ocular (endophthalmitis, chorioretinitis), cutaneous, and osteoarticular (costochondritis, hip arthritis).
- Simultaneous infections across multiple sites were observed in 8 patients.
- Biopsy and culture of cutaneous lesions emerged as the most effective method for microbiological diagnosis.
Impact:
- This study underscores the importance of recognizing disseminated candidiasis in intravenous drug users.
- It emphasizes the diagnostic value of skin biopsies and provides insights into the management of this severe fungal infection.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
