Tuberculous lymphadenopathy: a multicentre operational study of 6-month thrice weekly directly observed treatment

The value of multimodal ultrasonography in evaluating therapeutic response of cervical tuberculous lymphadenitis to anti-tuberculosis drugs

Purpose

In order to research the value of multimodal ultrasonography in evaluating therapeutic response of cervical tuberculous lymphadenitis to anti-tuberculosis drugs.

Materials and methods

Sixty-one patients with cervical tuberculous lymphadenitis were enrolled in this study. Ultrasound examination was performed before systemic standard anti-tuberculosis treatment and within 1-2 months after treatment, and the patients were divided into effective group and ineffective group according to the follow-up at the sixth month. The multimodal ultrasound signs of the two groups were compared and analyzed.

Results

In the effective group, there were significant differences in the maximum diameter of lymph nodes, the echo of the surrounding tissue and the enlargement of the contrast area before and after treatment (p < 0.05). At 1-2 months after treatment, there were significant differences in the maximum diameter, pus changes, CDFI, elasticity scores, echo of surrounding tissues, changes in enlarged and non-enhanced areas after contrast enhancement between the effective group and the ineffective group (p < 0.05).

Conclusion

The multimodal ultrasound signs of the appearance of internal pus or non-enhancement area enlargement, enhanced echo of the surrounding tissue and enlargement after CEUS are related to poor prognosis, and may be used to evaluate the response of anti-tuberculosis chemotherapy when the size change of lymph node is not obvious in individual treatment.

Is the Initial Size of Tuberculous Lymphadenopathy associated with Lymph Node Enlargement during Treatment?

There are little data on the changes in lymph node (LN) size during the treatment of tuberculous lymphadenopathy (TB LAP). This study aimed to provide data on LN changes during treatment. Between March 2014 and December 2015, 20 patients who were diagnosed with cervical TB LAP were enrolled. LN enlargement within two months (50%, 4/8 vs. 8.3%, 1/12; P = 0.04) was more frequently observed in patients with initial LN size ≥ 7.5 cm². Enlarged LNs were excised in three patients owing to pain and fistula formation. Initial LN size may be associated with LN enlargement during treatment.

Tuberculous lymphadenopathy: Experience from the referral center of Northern India

Background:

Lymphadenopathy is the common form of extrapulmonary tuberculosis (TB) in the developing country like India. The aim of the study was to assess the clinical and the pathological features of tuberculous peripheral lymphadenopathy along with the effect of the antitubercular drugs on its clinical course.

Materials and Methods:

A prospective study was carried out in the department of pulmonary medicine from July 2013 to June 2014. Clinico-demographical and pathological characteristics of the patients of tuberculous lymphadenopathy were studied.

Results:

Two and four cases, 84 (41.2%) male and 120 (58.8%) females were diagnosed as the cases of tuberculous lymphadenopathy. Mean age of the patients were 28.45 ± 12.83. Palpable mass (100%) was the most common presenting feature. Cervical lymphadenopathy (92.6%) was the most common presentation of peripheral tuberculous lymphadenopathy. Most common cytological pattern seen was epithelioid granuloma with caseous necrosis (32.84%) followed by epithelioid granuloma without caseous necrosis on fine needle aspiration cytology (FNAC). Directly observed treatment short course (DOTS) for TB was effective in treating tuberculous lymphadenopathy.

Conclusion:

Tuberculous lymphadenopathy affects female more often than males. FNAC is the effective mean in diagnosing tuberculous lymphadenopathy. DOTS is the effective mean for treating tuberculous lymphadenopathy.
