Clinical efficacy of short-course chemotherapy combined with topical injection therapy in treatment of superficial lymph node tuberculosis

Abstract

To evaluate the clinical efficacy and safety of short-course chemotherapy combined with regional injection therapy in the treatment of superficial lymph node tuberculosis. 201 patients diagnosed with superficial lymph node tuberculosis were retrospectively analyzed. All patients were randomly divided into the study (n = 100) and control groups (n = 101). In the study group, the patients received 6-month chemotherapy with isoniazid (H), rifampin (R) and ethambutol (E) (6HRE) in combination with regional injection of streptomycin, and their counterparts in the control group underwent systemic regime of 3HRZE/6HRE. In the study group, the overall cure rate was calculated as 98% and the recurrence rate was 2%. Twenty-four of 25 nodular type patients and 36 among 37 inflammatory type patients were recovered and discharged. One patient with huge nodular type mass was treated for 4 months and the mass size was slightly reduced. In the control group, the overall cure rate was 48.5% and the recurrence rate was 7.9%. The recurrent patients were further administered with regional injection of streptomycin based upon the chemotherapy regime until they were recovered. Combined therapy of systemic chemotherapy and regional injection of streptomycin is probably an efficacious and safe approach in the treatment of superficial lymph node tuberculosis, which remains to be validated by more investigations.
