Penelitian ini bertujuan mengetahui hubungan serum lipid darah dengan degenerative disc disease berdasarkan klasifikasi pfirrmann menggunakan magnetic resonance imaging lumbosacral pada pasien nyeri punggung bawah. Penelitian ini dilaksanakan di Departemen Radiologi RS. Dr. Wahidin Sudirohusodo Makassar mulai bulan Oktober 2018 sampai Januari 2019. Subjek sebanyak 52 orang dengan rentang usia 30 - 60 tahun. Metode yang digunakan adalah uji Spearman. Hasil penelitian menunjukkan terdapat korelasi antara kadar low-density lipoprotein (LDL) dan trigliserida serum dengan degenerative disc disease dengan nilai p=0.02 (p0.05). Semakin tinggi kadar LDL dan trigliserida maka derajat degerative disc disease cendereng semakin berat. Tidak terdapat korelasi antara HDL dengan degenerative disc disease. Secara statistik tidak terdapat korelasi antara kolesterol total dengan degenerative disc disease. Namun, didapatkan pada grafik nilai kolesterol total pada setiap derajat degenerative disc disease meningkat.

Abstract Objectives This study aimed to evaluate the association with coronary high-intensity plaque (HIP) on non-contrast T1-weighted magnetic resonance imaging (T1WI) and circulating levels of malondialdehyde-modified low-density lipoprotein (MDA-LDL). Methods A total of 139 patients with coronary artery stenosis (>70%) were imaged with non-contrast T1WI by using a 1.5-T magnetic resonance system (HIP: n=60, non-HIP: n=79). HIP was defined as a signal intensity of coronary plaque to cardiac muscle ratio (PMR) of ≥1.4. At admission, circulating levels of MDA-LDL and other lipid-related markers (triglyceride, HDL, LDL, Lp(a), RLP-C, and EPA/AA) were measured. Results Circulating levels of MDA-LDL (p=0.001) and LDL (p=0.041) were significantly higher in patients with HIP than those without, whereas the other lipid-related markers were not significantly different between both groups. In multivariable logistic regression analysis, MDA-LDL levels were independently associated with the presence of HIP (OR 1.03; 95% CI, 1.00–1.06, p=0.015) after adjusting for cofounding factors (age, sex, triglyceride, LDL, Lp(a), RLP-C, and EPA/AA). The optimal MDA-LDL threshold for predicting coronary HIP was 90.4 U/L, identified by the receiver operating characteristic curve. Conclusion MDA-LDL levels might be associated with the presence of HIP in patients with coronary artery disease.

Abstract Background Although elevated oxidized low-density lipoprotein could play critical roles in vulnerable plaque, there are no studies that compared coronary high-intensity plaque (HIP) on non-contrast T1-weighted magnetic resonance imaging (T1WI_MRI) and circulating malondialdehyde-modified low-density lipoprotein (MDA-LDL) levels for the prediction of cardiac events. Methods and results A total of 139 patients with coronary artery stenosis (>70%) were examined with non-contrast T1WI using a 1.5-T MRI (HIP: n=63, non-HIP: n=76). Scheduled percutaneous coronary intervention (PCI) for culprit lesions was performed within 48 h after MRI. HIP was defined as a signal intensity of coronary plaque to cardiac muscle ratio (PMR) of ≥1.4. At admission, circulating levels of MDA-LDL and other lipid-related markers were measured. We evaluated the subsequent cardiac events, which were defined as major adverse cardiac events (MACE; cardiac death, myocardial infarction, and/or ischemia-driven PCI) during follow-up periods (5.6±1.3 years). Circulating MDA-LDL levels were significantly higher in patients with HIP than in those without HIP (p<0.0001). MDA-LDL levels were significantly correlated with PMR (r=0.490, p<0.0001). In multivariable logistic regression analysis, MDA-LDL levels were independently associated with the presence of HIP (OR 1.05; 95% CI, 1.02–1.08, p<0.0001). The incidence of MACE was significantly higher in patients with HIP (27%) than in those without HIP (5%; p=0.011 by the log-rank test). In the multivariable Cox proportional hazard analysis, the MDA-LDL levels (HR 1.03; 95% CI:1.01–1.05, p=0.007) and PMR (HR 2.39; 95% CI:1.19–4.65, p=0.016) were significantly associated with MACE. For MACE prediction, the C-statistic values for MDA-LDL, PMR, and PMR+MDA-LDL were 0.724, 0.791, and 0.800, respectively. Compared with MDA-LDL alone, the addition of PMR to MDA-LDL increased the net reclassification improvement by 0.78 (p=0.012). Conclusions MDA-LDL levels might be associated with the presence of HIP in patients with coronary artery disease. Furthermore, adding PMR to MDA-LDL levels markedly improved MACE prediction.

Degenerative Disc

Degenerative changes of intervertebral discs is a very complicated process as a result of interaction of many factors: genetic, environmental, physical activity. Abnormalities in the vertebrae structure create the preconditions for the overload of the vertebral motor segment, which contributes to the spread of degenerative lesions and increases the risk of spinal injuries. Degenerative disc disease is one of the most common causes of back pain. The process of degeneration begins at a young age and in adulthood it often becomes widespread with a predominance of one or another localization. Methods of medical imaging occupy an important place in diagnosis of musculoskeletal pathologies. Radiography assesses the changes only in bone structures, but does not allow the visualization of soft tissues, which include not only the ligaments of the vertebral motor segment, but also the intervertebral discs. Magnetic resonance imaging is the most effective method for diagnosing degenerative changes in intervertebral discs. Possibilities of ultrasound examination in the diagnosis of early stage degenerative disc disease have not been studied enough. There were examined 147 patients aged 18−27 years with clinical and neurological signs of degenerative disease of cervical and lumbar spinal discs. Ultrasonic semiotics showed changes within the pulpal nucleus as an increased echogenicity and displacement back towards the fibrous ring, fibrous ring thinning, which indicated the disc protrusion. In patients with pain in neck and lower back, fragmentary imaging of the fibrous ring and prolapse of the disc contents into the lumen of spinal canal, indicating the development of hernias was found. The presence of herniated discs of cervical and lumbar spine in all cases coincided with the results of magnetic resonance imaging, and protrusion did in 91,4 % of cases. Thus, among medical imaging the ultrasonography is the most accessible and informative method for diagnosing degenerative changes in intervertebral discs of cervical and lumbar spine. Key words: degenerative disc disease, ultrasonography, cervical and lumbar intervertebral discs.
