ObjectiveTo summarize the research status and progress of interleukin-6 (IL-6) in Takayasu arteritis (TAK). MethodRecent literature published at home and abroad about the study of IL-6 in the TAK was reviewed and analyzed. ResultsIL-6 was a pro-inflammatory cytokine secreted by a variety of cells, which participated in a variety of inflammatory and immune reactions, and played an important role in the progress of TAK. The expression levels of IL-6 in the peripheral blood and vascular wall tissues of patients with TAK were increased. The gene polymorphism of IL-6 might be related to the occurrence of TAK. Tocilizumab, an IL-6 receptor antagonist, was effective and safe in the treatment of TAK. ConclusionsIL-6 can be used as one of the monitoring indicators for the active phase and recurrence of TAK. IL-6 receptor antagonist can be used as the treatment choice of TAK, but the application results in different stages of TAK are still worth expecting.
ObjectiveTo review and analyze the clinical manifestations of common aortitis in cardiac surgery. MethodsWe screened 41 552 patients who were hospitalized in the Department of Cardiac Surgery of Zhongshan Hospital, Fudan University from 2010 to 2020, analyzed the patients' clinical data, and classified according to the type of diseases. Then we summarized all their clinical manifestations. ResultsIn our center 145 patients were operated for aortitis diseases, including 75 males and 70 females, with the age of 24-76 (45.6±11.3) years. There were 61 patients of Takayasu's arteritis, 51 patients of Behcet's disease, 8 patients of syphilitic aortitis, 8 patients of systemic lupus erythematosus, 2 patients of Kawasaki disease, 4 patients of ankylosing spondylitis, 10 patients of dry syndrome, and 1 patient of scleroderma. ConclusionAortitis is not uncommon in cardiac surgery, and awareness of the disease should be enhanced. So that we can distinguish various types of aortitis and to make proper management to improve patients' prognosis.
ObjectivesTo explore the changes of some peripheral blood cells related to inflammation in patients with non-arteritis central retinal artery occlusion (NA-CRAO). MethodsA retrospective clinical study. From July 2019 to July 2021, a total of 218 patients with NA-CRAO hospitalized (NA-CRAO group) in Department of Ophthalmology, Xi'an People's Hospital (Xi'an Fourth Hospital) and 218 patients with routine physical examination (control group) during the same period were included in the study. There were no significant differences in age (t=0.60), sex composition ratio (χ2=0.83) and body mass index (t=0.77) between the two groups (P＞0.05). 0.2 ml fasting peripheral blood was collected from the subject, and white blood cells (WBC), neutrophils (NEUT), lymphocytes (LYMPH), red blood cells (RBC), RBC distribution width (RDW), platelets (PLT), mean PLT volume (MPV), and large PLT ratio (PLCR) were detected. The NEUT/LYMPH ratio (NLR) and PLT/LYMPH ratio (PLR) were calculated. t test was used to compare measurement data between groups. Multiple logistic regression analysis was performed for blood cells with P＜0.05. The receiver operating characteristic curve (ROC curve) was used to calculate the area under the curve (AUC) and 95% confidence interval (95%CI) of each inflammatory indicator, and the optimal cutoff value was determined according to the Jorden index (sensitivity+specificity－1). ResultsCompared with control group, WBC, NEUT, NLR, RDW, PLR were increased in NA-CRAO group, while RBC and LYMPH were decreased, with statistical significance (t=9.68, 12.43, 9.47, 3.64, 5.54, 5.18, 0.46; P＜0.001). There was no significant difference in PLT, MPV and PLCR between the two groups (t=0.32, 1.56, 0.84; P＞0.05). Multivariate logistic regression analysis showed that NLR was a possible risk factor for the occurrence of NA-CRAO (odds ratio=2.51, 95%CI 0.780-0.859, P=0.031). ROC curve analysis showed that the AUC predicted by NLR was 0.819, the optimal critical value was 3.05, and the sensitivity and specificity were 59.2% and 92.7%, respectively. ConclusionsIn peripheral blood cells of NA-CRAO patients, NEUT is significantly increased and LYMPH is decreased. NLR is a possible risk factor for NA-CRAO.
Objective To observe the clinical and imaging features of non-arteriotic central retinal artery occlusion (NA-CRAO) with internal boundary membrane detachment (ILMD), and to analyze its relationship with visual prognosis. MethodsA retrospective clinical study. A total of 88 patients with NA-CRAO hospitalized in Department of Ophtalmology, Xi'an People's Hospital (Xi'an Fourth Hospital) from January 2014 to June 2023 were included in the study. Best corrected visual acuity (BCVA), optical coherence tomography (OCT) and fluorescein fundus angiography (FFA) were performed. The BCVA test used the international standard visual acuity chart, which was statistically converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity. OCT observed the presence of ILMD and the thickening of the inner retina and the disappearance of anatomical stratification. FFA recorded arm-retinal circulation time (A-Rct) and retinal arterion-distal filling time (FT), and observed ciliary retinal artery, fluorescein retrograde filling, cotton spots, luciferin nodal filling, macular non-perfusion, capillary fluorescein leakage, optic disc strong fluorescence, choroidal background weak fluorescence and other characteristics. According to whether there was ILMD, the patients were divided into ILMD group and non-ILMD group, with 44 cases and 44 eyes respectively. The two groups received the same treatment. The follow-up time was 30 days after treatment. The clinical, FFA characteristics and BCVA before and after treatment were compared between the two groups. t-test was used for comparison between groups. ResultsIn ILMD group and non-ILMD group, there were 43 cases of male and 1 case of female, respectively, and the proportion of male was significantly higher than that of female. Before and after treatment, the logMAR BCVA of ILMD group and non-ILMD group were 2.35±0.42, 2.01±0.46, 1.47±0.60, 0.77±0.49, respectively. There were significant differences in logMAR BCVA between the two groups before and after treatment (t=8.025, 12.358; P＜0.001). Before treatment, A-Rct and FT in ILMD group were longer than those in non-ILMD group, and the difference was statistically significant (t=3.052, 3.385; P＜0.05). After treatment, there was no significant difference (t=1.040, 1.447; P＞0.05). The proportion of ciliary retinal artery and cotton plaque in ILMD group was lower than that in non-ILMD group. There was no significant difference in ciliary retinal artery between the two groups (χ2=－0.961, P＞0.05), but there was a significant difference in cotton wool plaque between the two groups (χ2=－3.364, P＜0.05). Compared to the non-ILMD group, The proportion of retrograde fluorescein filling in retinal artery (χ2=－2.846), segment filling (χ2=－3.907), macular non-perfusion (χ2=－6.656), capillary fluorescein leakage (χ2=－4.367), optic disc strong fluorescence (χ2=－3.525) and choroidal background weak fluorescence (χ2=－2.276) increased, the difference was statistically significant (P＜0.05). ConclusionsIn patients with NA-CRAO, compared with those without ILMD, those with ILMD have more severe retinal ischemia and worse BCVA before and after treatment. ILMD is one of the poor prognostic markers of NA-CRAO vision.
Objective To summarize the clinical characteristics of polyarteritis nodosa which begin with pulmonary lesions, so as to make early diagnosis and treatment possible. Methods Clinical data of three patients of polyarteritis nodosawhich began with pulmonary lesions were summarized includingmode of onset, evolvement of symptom and sign, data of laboratory test. The results of vascular ultrasound and histopathology examination were analyzed for their diagnostic value.Results Cough, sputum productive cough, and irregular high fever were present in the earlier period. Increases of C-reactive protein ( CRP) , erythrocyte sedimentation rate ( ERS) , white blood cell count ( WBC) , and anemia were main laboratory findings. Computed tomography revealed scattered infiltration in the lung. Anti-infective treatment was ineffective. Involvement of skin, kidney, gastrointestinal tract, nerve and muscle was present in sequence. Two of the three cases were confirmed by pathological biopsy. The symptoms were improved by the treatment with glucocorticoid. Conclusions Polyarteritis nodosa which begin with pulmonary lesions is easy to misdiagnose due to atypical symptoms. It is important for diagnosis of polyarteritis nodosa to collect evidence of systematic involvement through taking careful history and physical examination. Further angiography and biopsy can confirm the diagnosis. Cytotoxic drugs and/ or glucocorticoid are effective for the treatment of polyarteritis nodosa.
