Clinicoepidemiologic considerations in the diagnosis of tuberculous lymphadenitis: evidence from a high burden country.

OBJECTIVES

Tuberculosis is the biggest health issue worldwide, with tuberculous lymphadenitis (TBL) being its most common extrapulmonary manifestation. Clinical diagnoses of TBL often pose challenges; thus, this study aimed to analyze the clinical, epidemiologic, and laboratory aspects of TBL in Debre Markos Specialized Comprehensive Hospital, northwest Ethiopia.

METHODS

The study was conducted at Debre Markos Specialized Comprehensive Hospital from October 2019 to March 2021. Patients with lymphadenitis displaying cytomorphologic features of tuberculosis were enrolled. A checklist was used to collect clinicodemographic data.

RESULTS

Among a total of 294 patients with TBL, 237 (80.61%) were adults aged 15-45 years. A fluctuant consistency (177; 60.20%; n = 294) with predominant involvement of cervical lymph nodes (229; 77.8%) was the most frequent presentation. Most patients did not have either HIV infection (235; 94.37%; n = 261) or known chronic medical illnesses (250; 95.8%). Constitutional symptoms (113; 41.85%; n = 270) and chronic cough (56; 20.74%; n = 270) were infrequent. The erythrocyte sedimentation rate (ESR) was increased in the majority of patients (133; 80%; n = 165), of whom extreme elevation (≥100 mm/hour) seen in 63 (38.18 %) patients and the mean ESR for our participants was 78.64 mm/hour.

CONCLUSION

TBL typically presents as a fluctuant neck mass, predominantly in young adults. The majority of patients have no constitutional symptoms or cough. HIV infection or chronic medical illnesses are uncommon. The raised erythrocyte sedimentation rate is a fairly consistent finding.
