OBJECTIVE: To investigate the short-term effectiveness of the anterior and middle columns in thoracolumbar tuberculosis reconstructed with whole autogenous spinous process-laminar bone through posterior approach. METHODS: The retrospective study included 78 patients with thoracolumbar tuberculosis who underwent posterior approach surgery and anterior and middle column bone graft reconstruction between January 2012 and May 2023. Based on the type of autogenous bone graft used, patients were divided into group A (whole autogenous spinous process-laminar bone graft, 38 cases) and group B (autogenous structural iliac bone graft, 40 cases). There was no significant difference of baseline data, such as age, gender, disease duration, involved segment of spinal tuberculosis, and preoperative erythrocyte sedimentation rate (ESR), C reactive protein (CRP), Oswestry disability index (ODI), visual analogue scale (VAS) score, the American Spinal Injury Association (ASIA) grade, segmental kyphotic angle, and intervertebral height between the two groups ( P>0.05). The operation time, intraoperative blood loss, postoperative drainage, hospital stays, ESR, CRP, VAS score, ODI, bone fusion time, ASIA grade for neurological status valuation, postoperative complications, change of segmental kyphotic angle, change of intervertebral height were recorded and compared between the two groups. RESULTS: The operation time in group A was significantly shorter than that in group B ( P<0.05); there was no significant difference in intraoperative blood loss, postoperative drainage, and hospital stays between the two groups ( P>0.05). All patients in the two groups were followed up 14-110 months (mean, 64.1 months); there was no significant difference in the follow-up time between the two groups ( P>0.05). The ESR, CRP, ODI, and VAS score at each time point after operation in both groups significantly improved when compared with those before operation, and further improved with the extension of time, the differences were significant ( P<0.05). There was no significant difference between the two groups ( P>0.05) except that the VAS score of group A was significantly better than that of group B at 3 days after operation ( P<0.05). There was no significant difference in fusion time between the two groups ( P>0.05). The neurological function of most patients improved after operation, and there was no significant difference in ASIA grade between the two groups at last follow-up ( P>0.05). There was no significant difference in segmental kyphosis angle and intervertebral height between the two groups at each time point ( P>0.05), and no significant difference in segmental kyphosis angle, intervertebral height correction and loss were found between the two groups ( P>0.05). In group A, there was 1 case of incision fat liquefaction and 1 case of incision infection; in group B, there was 1 case of deep venous thrombosis, 2 cases of pleural effusion, and 10 cases of pain in bone harvesting area; in both groups, there were 2 cases of gout caused by hyperuricemia. There was a significant difference in the incidence of pain in bone harvesting area between the two groups ( P<0.05), and there was no significant difference in the incidence of other complications between the two groups ( P>0.05). CONCLUSION Whole autogenous spinous process-laminar bone grafting is equivalent to structural iliac bone graft in reconstruction of the anterior and middle columns in thoracolumbar tuberculosis through posterior approach, effectively supporting the stability of the anterior and middle columns of the spine, while resulting in shorter operation time and less postoperative pain in bone harvesting area.

Bone tuberculosis is one of the main lesions of extrapulmonary tuberculosis, and the affected site shows local pain and limited movement, and the severe patients face a higher risk of teratogenicity and disability. Especially in the context of the increasing spread of multidrug-resistant tuberculosis, it is particularly urgent to seek innovative treatment options. In recent years, vitamin D plays an important role in the prevention and treatment of bone tuberculosis, and the mechanism of action has been continuously explored. At the same time, vitamin D receptor gene polymorphism has also been found to be closely related to the susceptibility and risk of bone tuberculosis. This article reviewed the relationship between vitamin D and its receptor gene polymorphisms and the susceptibility to bone tuberculosis. It was found that vitamin D deficiency increased the susceptibility to bone tuberculosis in both adults and children, and multiple genotypes of vitamin D receptor had an effect on the susceptibility to bone tuberculosis, especially FokⅠ genotype. It may also be one of the reasons for the increase in the number of bone tuberculosis. Through the study of the relationship between vitamin D and its receptor gene polymorphism and the susceptibility to bone tuberculosis, some factors inducing bone tuberculosis can be avoided, and related new drugs can be more targeted, such as vitamin D supplements, gene receptor related antagonists, etc. To provide more systematic and targeted strategies for the prevention and treatment of bone tuberculosis.

BACKGROUND: Evidence on the combined effects of air pollutants and greenspace exposure on pulmonary tuberculosis (PTB) treatment is limited, particularly in developing countries with high levels of air pollution. OBJECTIVE: We aimed to examine the individual and combined effects of long-term exposure to air pollutants on PTB treatment outcomes while also investigating the potential modifying effect of greenspace. METHODS: This population-based study included 82,784 PTB cases notified in Zhejiang Province, China, from 2015 to 2019. The 24-month average concentrations of particulate matter with an aerodynamic diameter ≤2.5 µm (PM_2.5), ozone (O₃), nitrogen dioxide (NO₂), and sulfur dioxide (SO₂) before PTB diagnosis were estimated using a dataset derived from satellite-based machine learning models and monitoring stations. Greenspace exposure was assessed using the annual China Land Cover Dataset. We conducted analyses using time-varying Cox proportional hazards models and cumulative risk indices. RESULTS: In individual effect models, each 10 µg/m³ increase in PM_2.5, NO₂, O₃, and SO₂ concentrations was associated with hazard ratios for PTB treatment success of 0.95 (95% confidence interval (CI): 0.93-0.97), 0.92 (95% CI: 0.91-0.94), 0.98 (95% CI: 0.97-0.99), and 1.52 (95% CI: 1.49-1.56), respectively. In combined effect models, long-term exposure to the combination of air pollutants was negatively associated with PTB treatment success, with a joint hazard ratio (JHR) of 0.79 (95% CI: 0.63-0.96). Among the pollutants examined, O₃ contributed the most to the increased risks, followed by PM_2.5 and NO₂. Additionally, areas with moderate levels of greenspace showed a reduced risk (JHR = 0.81, 95% CI: 0.62-0.98) compared with the estimate from the third quantile model (JHR = 0.68, 95% CI: 0.52-0.83). CONCLUSIONS Combined air pollutants significantly impede successful PTB treatment outcomes, with O₃ and PM_2.5 accounting for nearly 75% of this detrimental effect. Moderate levels of greenspace can mitigate the adverse effects associated with combined air pollutants, leading to improved treatment success for patients with PTB.

OBJECTIVE: Cigarette smoking exacerbates the progression of pulmonary tuberculosis (TB). The role of tertiary lymphoid structures (TLS) in chronic lung diseases has gained attention; however, it remains unclear whether smoking-exacerbated lung damage in TB is associated with TLS. This study aimed to analyze the characteristics of pulmonary TLS in smokers with TB and to explore the possible role of TLS in smoking-related lung injury in TB. METHODS: Lung tissues from 36 male patients (18 smokers and 18 non-smokers) who underwent surgical resection for pulmonary TB were included in this study. Pathological and immunohistological analyses were conducted to evaluate the quantity of TLS, and chest computed tomography (CT) was used to assess the severity of lung lesions. The correlation between the TLS quantity and TB lesion severity scores was analyzed. The immune cells and chemokines involved in TLS formation were also evaluated and compared between smokers and non-smokers. RESULTS: Smoker patients with TB had significantly higher TLS than non-smokers ( P < 0.001). The TLS quantity in both the lung parenchyma and peribronchial regions correlated with TB lesion severity on chest CT (parenchyma: r = 0.5767; peribronchial: r = 0.7373; both P < 0.001). Immunohistochemical analysis showed increased B cells, T cells, and C-X-C motif chemokine ligand 13 (CXCL13) expression in smoker patients with TB ( P < 0.001). CONCLUSION Smoker TB patients exhibited increased pulmonary TLS, which was associated with exacerbated lung lesions on chest CT, suggesting that cigarette smoking may exacerbate lung damage by promoting TLS formation.

Objectives: This study aims to describe the clinical profile of patients with tuberculosis of the spine admitted at PCMC from the year 2012-2022. Moreover, this study aims to describe the clinical profile (age, gender, BMI, area of residence) of the patients with tuberculosis of the spine admitted at PCMC from the years 2012-2022. It also aims to present the known BCG vaccination status, exposure and risk factors (nutritional factors, comorbidities), of these patients. This study presents the symptomatology (including the spinal level of involvement, and severity, sensory or motor dysfunction) and the medical and/or surgical treatment and the outcome of these identified patients.

Materials and Methods: A retrospective chart review at PCMC analyzed children under 19 diagnosed with Pott’s Disease from January 2013 to December 2022. The study, approved by the Institutional Review Board, included demographic data, clinical manifestations, BCG vaccination status, treatment details, and outcomes, while excluding non-Filipino patients and readmissions.

Results: This study examined 41 pediatric patients with Pott’s disease at the Philippine Children’s Medical Center from 2012 to 2022, primarily affecting males aged 10-15. Most patients were from low-income backgrounds. Symptoms included chronic back pain, fever, and neurological issues, with advanced imaging required for diagnosis. While 93% had received BCG vaccinations, the correlation with disease severity was inconclusive. Treatment involved anti-tuberculous agents, with surgery for severe cases. Despite improvements, none were disease-free, highlighting chronic disabilities. The findings emphasize the need for better management of spinal tuberculosis and increased BCG vaccination among children in high TB-burden areas.

Conclusion: The study evaluated the clinical profile and clinical features of children with Pott’s Disease who were treated at the Philippine Children’s Medical Center (PCMC) between the years 2012-2022. The data from the study identifies the BCG vaccine may not prevent the onset of Pott's disease.

BACKGROUND

The Philippines faces a significant Human immunodeficiency virus (HIV) burden, but only 13% of pulmonary tuberculosis (PTB) patients are aware of their status. Barriers to testing include cost, access, risk perception, and stigma. 

OBJECTIVE

To determine the barriers to HIV counseling and testing among clinically confirmed pulmonary tuberculosis patients seen at Corazon C. Aquino Hospital.

METHOD

Cross-sectional research design was employed in this study. Socio-demographic profile and potential barriers to HIV counseling and testing of the respondents was analyzed through descriptive statistics, association was determined through Chi-square. Total enumeration sampling was employed, 33 clinically diagnosed PTB patients was included in this study. 

RESULTS

Results of the study showed 57.58% of respondents lack knowledge about HIV counseling and testing with M < 3.1212. The perceived personal barriers of the respondents are poor knowledge, not perceiving themselves as at risk, and 48.48% not perceiving a benefit in accepting HIV counseling and testing. Socioeconomic barriers include privacy, cost, and fear of rejection from family and friends. Health institutional barriers include unfriendly service providers, privacy issues, queues, delayed results, remote locations, and unavailability. The demographic profile did not significantly correlate with these barriers. 

CONCLUSION

Increase awareness across all populations is recommended since no correlation with demographic profile was found in this study. Mixed-methods is recommended in this study, to reduce recall bias, validate respondents’ narratives and explore other perceived barriers, increase in sample size is also recommended.

OBJECTIVE: To investigate the efficacy of posterior three-columns osteotomy in the treatment of severe tuberculous angular kyphosis. METHODS: Total of 33 patients with severe tuberculous angular kyphosis were treated with posterior three-columns osteotomy from January 2006 to January 2019 including 24 males and 9 females with an average age of (40.6±23.3) years old ranging from 15 to 62 years old and an average disease duration of (23.5±15.5) years ranging from 4 to 40 years. The Cobb's angle of kyphosis was (118.65±28.82)°. Interradicular bone-disc-bone osteotomy(BDBO), posterior-only vertebral column resection (PVCR) and posterior multilevel vertebral osteotomy (PMVO) were performed to correct spinal deformity individually. The visual analogue scale (VAS), Oswestry disability index (ODI), sagittal vertical axis (SVA), ASIA spinal cord functional classification and motor function score, and deformity correction rate were measured and statistically analyzed before, after and at the final follow-up. RESULTS: Total of 33 patients were followed up from 15 to 96 months with an average of (38.00±6.38) months. The last follow-up of kyphosis Cobb angle (23.88±5.45)° showed no significant loss from postoperative 12 months (20.40±9.13)°, P>0.05. The SVA, VAS, ODI and ASIA spinal cord functional classification and motor function score were significantly improved at 1 year and last follow-up after operation(P<0.01). The fusion time of the osteotomy site was (18.50±5.16) months. The ASIA classification of 15 patients with spinal cord injury were improved by at least 2 grades after operation, and their daily life and work ability were various levels of restored. Postoperative complications of spinal cord injury occurred in 3 cases. CONCLUSION Posterior three-columns osteotomy is the most effective method for the treatment of angular kyphosis of spinal tuberculosis.Careful preoperative design and individualized osteotomy can not only correct the deformity, but also a successful decompression to the spinal cord and promote the recovery of spinal cord function.

Tuberculosis can coexist with malignancy in the same organ, but cancer with TB in the cervix is rare. This is a case of cervical tuberculosis diagnosed in a cervical cancer patient after concurrent chemoradiotherapy and brachytherapy. This is the case of a 38-year-old G2P2 (2002) diagnosed with squamous cell carcinoma, large cell non-keratinizing cervix, Stage IIIB. The patient underwent concurrent chemoradiotherapy and brachytherapy. One month after the last brachytherapy dose, the attending physician noted a nodularity on the anterior lip of the cervix. A cervical punch biopsy was done to rule out tumor persistence. The histopathology revealed chronic granulomatous inflammation with Langhan’s type multinucleated giant cells consistent with tuberculous infection. She was diagnosed with cervical tuberculosis, postulated to be from latent TB reactivation, and was given Anti-Koch’s medication for six months. After receiving Anti-Koch’s treatment, the cervical nodularity was no longer appreciated, and the rest of the cervix was smooth on palpation. Her Pap Test was negative for any intraepithelial lesion and was declared with no evidence of carcinoma. A possible latent TB infection should always be screened in cancer patients from high-burden areas or those with close contact treated for tuberculosis because immunosuppression during cancer treatment can cause the reactivation of tuberculous disease. Cervical tuberculosis complicating cervical malignancy is treatable with Anti-Koch’s therapy and has not been shown to affect the course of the carcinoma.
Latent Tuberculosis

OBJECTIVE: We aimed to understand the willingness and barriers to the acceptance of tuberculosis (TB) preventive treatment (TPT) among people with latent TB infection (LTBI) in China. METHODS: A multicenter cross-sectional study was conducted from May 18, 2023 to December 31, 2023 across 10 counties in China. According to a national technical guide, we included healthcare workers, students, teachers, and others occupations aged 15-65 years as our research participants. RESULTS: Overall, 17.0% (183/1,077) of participants accepted TPT. There were statistically significant differences in the acceptance rate of TPT among different sexes, ages, educational levels, and occupations ( P < 0.05). The main barriers to TPT acceptance were misconceptions that it had uncertain effects on prevention (57.8%, 517/894), and concerns about side effects (32.7%, 292/894). CONCLUSION An enhanced and comprehensive understanding of LTBI and TPT among people with LTBI is vital to further expand TPT in China. Moreover, targeted policies need to be developed to address barriers faced by different groups of people.
