ABSTRACT
BACKGROUND: Management of lymphadenopathy caused by nontuberculous mycobacteria (NTM) is primarily surgical. Where this cannot achieve sufficient clearance of infected nodes, chemotherapy is often given. AIM: This study compared results of surgery alone with surgery followed by chemotherapy in instances where there was incomplete surgical removal of diseased tissue. METHODS: Chemotherapy comprised azithromycin 10 mg/kg and rifabutin 6 mg/kg both given once daily for 6 mo. Ninety-eight children with NTM infection were seen in the period 1990-2004. Sixty-eight cases with adenopathy where "time to healing" (discharge stopped and inflammation settled) was known were available to compare response to treatment. RESULTS: The median (range) "time to healing" in weeks for 43 patients who had surgery alone was: incision and drainage (I&D)/curettage 6 (1-72) (n = 10); excision 3 (1-28) (n = 22); and from the last operation of multiple (repeat) surgery 3 (1-40) (n = 11). For 25 patients who required chemotherapy in addition to surgery, the median (range) "time to healing" in weeks was I&D/curettage 10 (1-40) (n = 17), excision 14 (8-20) (n = 2) and multiple surgery 29 (2-88) (n = 6). CONCLUSION: In children with adenitis due to NTM, where surgical resection is followed by continued discharge and inflammation, chemotherapy should be considered before further surgery is undertaken.
