Abstract:
We aimed to determine the following things: the frequency of patients with Mediterranean spotted fever (MSF) during the last 10 years among those patients admitted with fever and rash, their clinical features, and the factors predicting the diagnosis of MSF among patients admitted with fever and rash. Between 1993-2002, the files of all patients admitted to our hospital with fever and rash were collected. The clinical features and serologic results of the patients diagnosed with MSF were further investigated. The diagnosis of MSF was established by epidemiological and clinical features and also by the clinical response within 2 days after doxycycline treatment. During the previous 10 years, 140 patients were admitted with fever and rash, and 15 (10%; four females, 11 males; mean age: 41 years; range: 17-70) of them were diagnosed with MSF. Clinical features were as follows: fever (100%), rash (100%), myalgia and/or arthralgia (93%), headache (87%), petechiae (27%), tache noire (13%), leucocytosis (74%), thrombocytopenia (33%), and accelerated erythrocyte sedimentation rate (100%). In nine of these patients, the diagnosis of MSF was established by epidemiological and clinical features and was confirmed by serologic studies. As a complication, one patient developed facial paralysis. Six (40%) were given several antibiotics. In conclusion, MSF should be considered in the differential diagnosis when a patient is admitted with fever, maculopapular rash, headache, myalgia and/or arthralgia, especially in spring, summer, or autumn.
Insights
Mediterranean spotted fever (MSF) is a significant cause of fever and rash, occurring in 10% of patients over a decade. Early consideration of MSF in differential diagnoses is crucial for timely treatment.
Area of Science:
- Infectious Diseases
- Epidemiology
- Clinical Medicine
Background:
- Mediterranean spotted fever (MSF) is an important tick-borne illness.
- Accurate diagnosis relies on clinical presentation and epidemiological factors.
- Prompt treatment is essential to prevent complications.
Purpose of the Study:
- To determine the frequency of MSF among patients presenting with fever and rash.
- To describe the clinical features of MSF.
- To identify factors predicting MSF diagnosis.
Main Methods:
- Retrospective analysis of patient records from 1993-2002.
- Inclusion criteria: patients admitted with fever and rash.
- Diagnosis confirmed by clinical response to doxycycline, epidemiological, and serologic data.
Main Results:
- 15 out of 140 (10.7%) patients admitted with fever and rash were diagnosed with MSF.
- Common symptoms: fever, rash, myalgia/arthralgia, headache.
- Key laboratory findings: leucocytosis, thrombocytopenia, accelerated ESR.
Conclusions:
- MSF is a notable diagnosis in patients with fever and rash, particularly during warmer months.
- Clinical features like fever, rash, headache, and myalgia are highly suggestive of MSF.
- Consider MSF in differential diagnosis for patients presenting with these symptoms, especially in endemic areas.
