- Case of a 13-year-old female patient, from the urban area of Cali, who presented with fever associated to tachypnea and generalized maculopapular exanthema on the trunk and limbs. During the first 48 hour in the pediatric ICU she developed a rapid clinical deterioration, persistent fever, increased acute phase reactants, bilateral interstitial pulmonary infiltrates and pleural effusion requiring noninvasive ventilation. Treatment with doxycycline was initiated due to a suspected possible infection by rickettsial agents. Twenty-four hours later the patient presented clinical improvement, resolution of the exanthema and removal of non-invasive ventilation. By means of indirect immunofluorescence test, titers of 1:512 were shown against typhus group, noting the probable diagnosis of murine typhus. |
