Abstract:
Authors present a prospective study of 130 cases of Mediterranean spotted fever treated between 1983 and 1985 in two Departments of Paediatrics of the Valles Occidental, area near Barcelona. Thirty-eight percent of the children came from suburban areas, an urban areas, an urban or rural origin being less frequent. Previous contacts with dogs existed in 86% of the cases. Most frequent clinical signs were fever (100%) maculo-papular rash (97%) and arthromyalgias (70%). The "tache noire" was found in 87% of the cases. Presence of arthritis in two patients is underlined. Indirect immunofluorescence to Rickettsia conorii was positive (much greater than 1/40) in 75% of the cases. All patients improved after treatment with tetracycline or erythromycin. There were no relapse.
Insights
Mediterranean spotted fever in children is often linked to dog contact, presenting with fever and rash. Prompt treatment with antibiotics like tetracycline or erythromycin leads to full recovery without relapse.
Area of Science:
- Pediatrics
- Infectious Diseases
- Rickettsial Infections
Context:
- Prospective study conducted in Valles Occidental, Spain (1983-1985).
- Focused on 130 pediatric cases of Mediterranean spotted fever.
- Investigated clinical signs, risk factors, and treatment outcomes.
Purpose:
- To describe the clinical presentation and epidemiology of Mediterranean spotted fever in children.
- To evaluate the effectiveness of tetracycline and erythromycin in treating the infection.
- To highlight key diagnostic indicators such as 'tache noire' and serological confirmation.
Summary:
- Fever (100%), maculo-papular rash (97%), and arthralgia (70%) were predominant symptoms.
- The characteristic 'tache noire' was observed in 87% of cases.
- Rickettsia conorii indirect immunofluorescence was positive in 75% of patients.
Impact:
- Demonstrates high efficacy of tetracycline and erythromycin, achieving complete recovery in all treated children.
- Confirms the importance of early diagnosis and antibiotic intervention for favorable outcomes.
- Provides valuable epidemiological data on Mediterranean spotted fever in a specific pediatric population.
