Bacille Calmette-Guerin Lymphadenitis: A single center experience

To describe the clinical presentation, course and management of infants that presented with the diagnosis of lymphadenitis after Bacille Calmette-Guerin (BCG) vaccination. This is a descriptive study of 89 patients that were referred to the pediatric infectious disease clinic at King Hussein Medical Center in Jordan with regional lymphadenitis after BCG vaccination. The presentation, course and treatment options of these cases were discussed. The study was conducted between September 2006 and September 2007. Eighty-nine patients (47 males (53%) and 42 females (47%) were studied. All infants received the same type of vaccine used by our Ministry of Health, which is the Danish strain. Unilateral axillary lymph node enlargement was the most commonly seen (47%). Cervical lymph nodes were noted in 22 patients (25%) and supraclavicular lymphadenopathy was seen in 16 (18%). Sinus formation was seen in 16 (18%) patients. 27 cases (30%) had fluctuating lymph nodes. Four infants had disseminated infection. The majority (65%) of patients had their symptoms starting within the first 2 months after BCG vaccination. Forty-two (47%) infants had conservative observational management. Anti-tuberculosis medications were commenced in 27 (30%). Surgical excision was performed in 10 (11.5%) cases. All infants but one had complete recovery by the end of the study period. BCG lymphadenitis is a potential complication that necessitates an early recognition and implementing appropriate treatment protocols. Complete healing of suppurative lymphadenitis after BCG vaccine can be achieved using different treatment protocols.
