Transcriptome analysis of the diseased intervertebral disc tissue in patients with spinal tuberculosis.

OBJECTIVE: To investigate the differential expression genes (DEGs) in spinal tuberculosis using transcriptomics, with the aim of identifying novel therapeutic targets and prognostic indicators for the clinical management of spinal tuberculosis. METHODS: Patients who visited the Department of Orthopedics at the Second Hospital, Lanzhou University from January 2021 to May 2023 were enrolled. Based on the inclusion and exclusion criteria, there were 5 patients in the test group and 5 patients in the control group. Total RNA was extracted and paired-end sequencing was conducted on the sequencing platform. After processing the sequencing data with clean reads and annotating the reference genome, FPKM normalization and differential expression analysis were performed. The DEGs and long non-coding RNAs (LncRNAs) were analyzed for Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) enrichment. The cis-regulation of differentially expressed mRNAs (DE mRNAs) by LncRNAs was predicted and analyzed to establish a co-expression network. RESULTS: This study identified 2366 DEGs, with 974 genes significantly upregulated and 1392 genes significantly downregulated. The upregulated genes are associated with cytokine-cytokine receptor interactions, tuberculosis, and TNF-α signaling pathways, primarily enriched in biological processes such as immunity and inflammation. The downregulated genes are related to muscle development, contraction, fungal defense response, and collagen metabolism processes. Analysis of LncRNAs from bone tuberculosis RNA-seq data detected a total of 3652 LncRNAs, with 356 significantly upregulated and 184 significantly downregulated. Further analysis identified 311 significantly different LncRNAs that could cis-regulate 777 target genes, enriched in pathways such as muscle contraction, inflammatory response, and immune response, closely related to bone tuberculosis. There are 51 genes enriched in the immune response pathway regulated by cis-acting LncRNAs. LncRNAs that regulate immune response-related genes, such as upregulated RP11-451G4.2, RP11-701P16.5, AC079767.4, AC017002.1, LINC01094, CTA-384D8.35, and AC092484.1, as well as downregulated RP11-2C24.7, may serve as potential prognostic and therapeutic targets. CONCLUSION: The DE mRNAs and LncRNAs in spinal tuberculosis are both associated with immune regulatory pathways. These pathways promote or inhibit the tuberculosis infection and development at the mechanistic level and play an important role in the process of tuberculosis transferring to bone tissue.

Spinal osteotomy to correct kyphosis in spinal tuberculosis.

Twenty-seven patients with severe tuberculous kyphosis have been treated at the National Murayama Hospital between 1966 and 1977. We have undertaken curettage of the foci and vertebral osteotomy through an anterior approach, followed by gradual correction with a halo pelvic distraction apparatus and subsequent vertebral fusion. Choice of this method depends upon the age of the patient, the degree of kyphosis before correction, and the presence of concomitant lesions. Details of postoperative management are given and their importance is emphasized. The major risks of correction are discussed and precautions suggested.

Results of treatment of spinal tuberculosis by "middle-path" regime.

The efficacy of modern drugs in the treatment of tuberculosis of the spine has been evaluated by a personal follow-up for three to ten years. Operation on the vertebral lesion was done only for those patients with or without neural complications who failed to respond favourably to drug therapy and rest. Thus absolute indications for operation were present in only 6 per cent of cases without neural involvement and in 60 per cent of patients with neural deficit. Of patients who responded to drug therapy alone, only 19 per cent revealed increase of kyphosis by more than 10 degrees. The diseased area showed radiological evidence of osseous replacement of 29-6 per cent of cases, of fibro-osseous union in 50 per cent and of fibrous replacement in 20-2 per cent. The overall results of this regime compare favourably with those of radical operation. It is suggested that treatment should in the first place be by modern antitubercular drugs.

Atypical manifestations of spinal infections.

Because of alarming delays in the diagnosis and treatment of vertebral osteomyelitis we have reviewed our experience over the past 15 years. Of the 36 cases, 25 were pyogenic and 11 tuberculous. Because of late referral there was a delay from onset of symptoms to diagnosis of at least three months in 13 patients. The reason for this was the failure of the initial physician to consider osteomyelitis in the differential diagnosis of a febrile illness associated with back pain. The majority of our patients from the onset did not have intense localized pain, tenderness and a high fever which is the classical clinical picture in this condition. Seven patients with a long history required surgical exploration and debridement of the lesion in order to eradicate the infection. The remainder did well on 6 to 12 weeks of antibiotic therapy. None required spinal fusion. Ten of 11 patients with spinal tuberculosis had curettage of the lesion and spinal fusion. Patients with diabetes, malignancy, alcoholism, corticosteroid therapy and recent lower urinary tract surgery were found to be at particular risk of developing spinal osteomyelitis. Very often it was difficult to identify differences in the presentation of pyogenic and tuberculous infections.

[Extrapulmonary tuberculosis in Africans (author's transl)].

Extra pulmonary tuberculosis are frequent in Africa and have a special severity due to delayed diagnosis and multifocal forms. Various punctures and biopsies may be necessary to demonstate the tuberculous infection. Even with modern treatment it too often implies important risks of severe sequelae.

[Selective spinal arteriography in vertebral and paravertebral disease processes (author's transl)].

Selective arteriography was performed on 15 patients with vertebral and paravertebral diseases. This procedure is particularly justified if the bone changes are of possible vascular origin, if the presence of arterial involvement by neoplasm is to be determined, or if one wishes to judge the extent of intraspinal or paravertebral spread of a spinal tumour. Up to a point, angiography may indicate the histology and malignancy of a mass. In the diagnosis of vertebral and paravertebral disease, selective spinal arteriography would come into competition with computed tomography. Either procedure should only be used if conventional methods are incapable of solving the diagnostic problem.

[Value of disk puncture in the diagnosis of infectious spondylodiskitis. Apropos of 48 punctures].

The authors report on their experience with discal puncture in the bacteriological diagnosis of 48 infectious spondylodiscites. This technique makes it possible to obtain a bacteriological certitude in 31 cases (65 per cent): Pott's disease (40 per cent) and 12 pyogene spondylodiscites (25 per cent), with 17 punctures remaining negative, including 5 technical failures, the needle not penetrating into the pinched disc. No incident was noted, demonstrating the harmless nature of this method. The authors insist upon the necessity of washing the disc in order to decrease the percentage of failures.
