Objective: Cat scratch disease (CSD) is the infectious disease caused by Bartonella henselae. Its typical presentation is regional lymphadenopathy. Also it may present with symptoms related to involved organs or disseminated disease with fever of unknown origin (FUO). Here children with CSD are evaluated to increase awareness about disease.
Materials and Methods: A total of 29 children diagnosed with CSD between 2019 and 2022 were involved in the study. Patients’ demographic characteristics, clinical, laboratory and radiological findings, treatments, and outcomes were analyzed.
Results: Seventeen of the patients were male, 12 were female, and their mean age was 116.5 ± 51 months. About 69.6% of them had a history of cat contact. Twenty-seven patient (93.1%) had lymphadenopathy, mostly axillary involved (61.5%). Other manifestations were disseminated disease presented with FUO, neuroretinitis, and encephalopathy. Twenty-seven patients (93.1%) had received antibiotics before admission without any improvement. Ultrasound showed that the affected lymph nodes were conglomerated, lobulated contoured, and cortical thickened, with one-third having cystic suppurative components. Serologic tests were positive in 24 of 27 patients. Twenty-one patients gave response to 5 days azithromycin treatment, in 8 patients this treatment extended to 10-14 days, rifampicin with/without doxycycline was given to 6 patients, and steroids were given to 3 patients.
Conclusion: In case of regional lymphadenopathy, especially axillary, not responding to nonspecific antibiotics CSD should be suspected. Cat contact history and serological and ultrasonographic findings are useful for diagnosis. Even if CSD responds well to azithromycin, sometimes prolongation of azithromycin and addition of other antibiotic or steroid may be required.
