Bacillus Calmette-Guerin lymphadenitis: a 6-year experience in two Saudi hospitals.

BACKGROUND

The World Health Organization (WHO) has recommended Bacillus Calmette-Guerin (BCG) vaccination as a part of the global expanded program for immunization. Although the BCG vaccine is usually a safe vaccine, a number of complications with lymphadenitis being the most common complication, can occur.

AIM

We evaluated the frequency, the clinical presentation and treatment modalities of lymphadenitis after BCG vaccine in Saudi children.

RESULTS

A total of 145 patients with BCG lymphadenitis presented between January 2005 and December 2010. In the majority (103) of the cases, the lymphadenitis involved ipsilateral left axillary nodes. Other sites of involvement included the left supraclavicular lymph nodes in 26 (18%) patients, and both the left axillary and supraclavicular lymph nodes were involved in 7 cases (4.8%). A total of 75 patients (65%) were given antituberculous medication. Eight (27%) patients had positive acid-fast bacilli and positive cultures for Mycobacterium bovis.

CONCLUSION

In light of the findings of this study, it would be advisable to administer the BCG vaccine in Saudi Arabia at a time later than at birth, as the younger children are commonly affected.
