Efficacy of single-stage posterior surgery for HIV-positive patients with thoracolumbar tuberculosis.

OBJECTIVE

We aimed to observe the clinical effect of single-stage posterior surgery on HIV-positive patients with thoracolumbar tuberculosis.

METHODS

From October 2015 to October 2019, 13 HIV-positive patients with thoracolumbar tuberculosis who underwent single-stage posterior surgery were retrospectively analyzed (observation group), and 13 HIV-negative patients with thoracolumbar tuberculosis who were matched with the gender, age, operative site, and surgical approach during the same period were selected as the control group. Postoperative complications, hemoglobin, albumin, CD4T lymphocyte count, operative site, operative time, and blood loss were recorded between the two groups. The clinical efficacy was evaluated by the visual analog scale (VAS), American Spinal Injury Association (ASIA) scale, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), kyphotic angle, correction rate of kyphosis, angle loss, and bone graft fusion time.

RESULTS

In the observation group, 7 patients had postoperative complications, including 1 patient with cerebrospinal fluid leakage, 1 patient with nerve root irritation, 1 patient with an opportunistic infection, and 4 with delayed wound healing. In the control group, 2 patients developed postoperative complications, including 1 with nerve root irritation and 1 with delayed wound healing. There was no statistically significant difference in the incidence of postoperative complications between the two groups (P > 0.05). CD4T lymphocyte count, hemoglobin, and albumin in HIV-positive patients with postoperative complications were statistically different from those without postoperative complications (P all < 0.05). No tuberculosis recurrence was found at the last follow-up, ESR and CRP returned to normal, and there were no statistically significant differences in bone graft fusion time, VAS score, ASIA scale, correction rate of kyphosis, and angle loss between two groups (P all > 0.05).

CONCLUSION

Single-stage posterior surgery for HIV-positive patients with thoracolumbar tuberculosis could achieve satisfactory clinical efficacy through comprehensive preoperative evaluation, standardized perioperative antiviral and anti-tuberculosis treatments, and prevention of postoperative complications.
