COVID-19 and low back pain: previous infections lengthen recovery time after intradiscal ozone therapy in patients with herniated lumbar disc

Abstract

Purpose To assess and compare the clinical effectiveness of percutaneous intradiscal ozone therapy in patients affected by lumbar disc herniation, with and without history of COVID-19 infection. Materials and Methods After the rising of COVID-19 pandemics in Italy, 47 consecutive percutaneous intradiscal ozone therapies were performed on patients with low back pain and/or sciatic pain due to lumbar disc herniation. Among these, 19 had suffered from COVID-19 and successively recovered with no residual symptoms, while the remaining 28 had not previously been affected by COVID-19 and were not convalescent. Oswestry Disability Index (ODI) was administered before the treatment and at 1-month and 3-month follow-up in order to assess the clinical outcome. Results The two groups were similar in terms of patient age ( p -value 0.54), treated levels ( p -value 0.26) and pre-procedure ODI ( p -value 0.33). Technical success was achieved in all cases. In patients previously affected by COVID-19, mean ODI decrease was 11.58 ± 9.51 (35.72%) at 1-month follow-up and 20.63 ± 9.87 (63.63%) at 3-month follow-up. In patients never affected by COVID-19, mean ODI decrease was 20.93 ± 10.53 (58.73%) at 1-month follow-up and 22.07 ± 11.36 (61.92%) at 3-month follow-up. Eventually, clinical success was registered in 84.21% (16/19) of patients with history of COVID-19 infection and in 85.71% (24/28) of patients with no history of COVID-19 infection. No major complication was registered. Conclusions In case of lumbar disc herniation treated with percutaneous intradiscal ozone therapy, patients previously affected by COVID-19 showed a significantly longer recovery time.

From drugs to biomaterials: a review of emerging therapeutic strategies for intervertebral disc inflammation

“…The intervention results in an augmentation of oxygen delivery to the intervertebral disc, eliciting a stimulation of cellular proliferation and production of extracellular matrix components, ultimately facilitating the process of tissue healing. Francesco Somma conducted a study wherein the Oswestry Disability Index (ODI) showed a substantial reduction among patients with disc herniation who had previously been infected with the novel coronavirus following ozone therapy ( Somma et al., 2022 ).…”

Gender Medicine in Clinical Radiology Practice

“…The pandemic has also necessitated the development of models to support clinical practice using artificial intelligence (AI) techniques [ 91 , 92 , 93 , 94 ]. Currently, the supporting models reported in the literature regarding COVID-19 have mainly focused on epidemic trends, early screening, and CT diagnosis as well as prognosis [ 95 , 96 , 97 , 98 , 99 , 100 ].…”

Radiation Recall Pneumonitis: The Open Challenge in Differential Diagnosis of Pneumonia Induced by Oncological Treatments

“…With regard to treatment-related pneumonitis chest radiography, due to its low specificity, it can be used as a screening investigation, while the role of PET is still unclear due to the potential overlap of the metabolic activity of infectious processes with malignant tumors. Chest CT allows early parenchymal changes and their evolution to be evaluated, thus representing the gold standard for the study of lung parenchyma [ 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 ]. Nevertheless, diagnosis is complicated due to the overlapping of the various CT patterns, and in this scenario, we should consider radiation pneumonia (RP), pneumonia by immune checkpoint inhibitors (CIP) and the possibility that the lung involvement is due to disease progression that may be manifested as pulmonary lymphangitis [ 89 ].…”
