HIV predisposes patients to opportunistic infections. However, with the establishment of Highly Active Anti-Retroviral Therapy (HAART), patients’ CD4 counts are maintained, as is a near normal life expectancy. This study aimed to establish the impact of HIV on the bacteriology of spondylodiscitis in a region in which tuberculosis (TB) is endemic, and to identify factors that might distinguish between them. Between January 2014 and December 2015, 63 consecutive cases of spontaneous spondylodiscitis were identified from a single-centre, prospectively maintained database. Demographics, presenting symptoms, blood results, HIV status, bacteriology, imaging, and procedure undertaken were reviewed and comparisons made of TB, non-TB, and HIV groups. There were 63 patients (22 male, 41 female) with a mean age of 42.0 years (11 to 78; Aims
Patients and Methods
Tuberculosis (TB) remains endemic in many parts
of the developing world and is increasingly seen in the developed world
due to migration. A total of 1.3 million people die annually from
the disease. Spinal TB is the most common musculoskeletal manifestation,
affecting about 1 to 2% of all cases of TB. The coexistence of HIV,
which is endemic in some regions, adds to the burden and the complexity
of management. This review discusses the epidemiology, clinical presentation,
diagnosis, impact of HIV and both the medical and surgical options
in the management of spinal TB. Cite this article:
The lack of an accurate, rapid diagnostic test
for mycobacterium tuberculosis (TB) is a major handicap in the management
of spinal TB. GeneXpert, a new, rapid molecular diagnostic test
is recommended as the first line investigation for suspected pulmonary
TB in areas with a high prevalence of HIV or drug resistance, yet
it has not been validated for the diagnosis of musculoskeletal TB. The aim of this study was to assess the accuracy of GeneXpert
in diagnosing spinal TB. A prospective clinical study of 69 consecutive adults with suspected
spinal TB was conducted at a tertiary hospital in an area with the
highest incidence and prevalence of TB in the world. GeneXpert was
used on tissue samples of the enrolled patients and its diagnostic
accuracy compared with a reference standard of tissue in liquid culture.
A total of 71 spine samples from 69 patients (two re-biopsies) were
included in the study. The GeneXpert test showed a sensitivity of 95.6% and specificity
of 96.2% for spinal TB. The results of the GeneXpert test were available
within 48 hours compared with a median of 35 days (IQR 15 to 43)
for cultures. All cases of multi-drug resistant TB (MDR TB) were
diagnosed accurately with the GeneXpert test. The MDR TB rate was
5.8%. Cite this article:
