PURPOSE: To investigate the treatment of severe bacterial endophthalmitis. METHODS:The curative effects of vitrectomy after intravitreal antibiotics and steroids (IVAS)for the treatment of 23 patients with bacterial endophthalmitis
(group I)and vitrectomy and IVA at the same time for the treatment of 28 patients with bacterial endopbthalmitis (group I)were analyzed retrospectively. RESULTS: The rate of curative effects of two groups were similar,while the marked curative effects in group I (47.8% )was significantly higher than that of the group I (17.9%). The average period of eliminating infiamation of group I was longer than that of group I , and the incidence of postoperative retinal detachment of group Ⅱ was 3 times more than that of group I . CONCLUSION :It was indicated that vitrectomy after IVAS may increase the security of vitrectomy and the curative effects of severe bacterial ndophthalmitis.
Objective To evaluate the efficacy of treatment of thyroid-associated ophthalmopathy with retrobular injection of glucocorticoid. Methods We searched The Cochrane Library (Issue 1, 2010), EBM Reviews, PubMed and CBMdisc to collect randomized controlled trials (RCTs) of retrobular injection of glucocorticoid for thyroid-associated ophthalmopathy. The quality of the included trials was assessed and meta-analyses were conducted by RevMan 4.2.8 software. We conducted subgroup analyses based on the outcome measures and intervention. Results A total of 7 RCTs were identified. There were significant differences between retrobular injection of glucocorticoid and blank in the effective rate (RR= 1.35, 95%CI 1.10 to 1.65, P=0.004). There were no significant differences between retrobular injection of glucocorticoid and oral glucocorticoid in the effective rate (RR= 1.15, 95%CI 0.93 to 1.42, P=0.20). And there were significant differences between retrobular injection of glucocorticoid alone and retrobular injection of glucocorticoid combined with radiotheraphy in the effective rate (RR= 0.85, 95%CI 0.72 to 1.00, P=0.04). Three patients of the ROGC experienced intraorbital hemorrhage and two of the ROGC experienced aggravation of soft tissues. There were no systemic adverse reactions such as weight gaining and Cushing’s syndrome. Conclusion Retrobular injection of glucocorticoid appears to be an effective treatment for thyroid-associated ophthalmopathy. And combination retrobular injection of glucocorticoid with radiotheraphy seems to be more effective.
ObjectiveTo explore significance of glucocorticoid for rat liver transplantation model.
MethodsTwo hundred rats were randomly divided into experimental group and control group. The experimental group rats were injected with sulfate atropine resulotion 0.1 mg/kg, cephazolin-Na 0.3 g/kg and hydrocortisone 5 mg/kg while the control group rats were injected with sulfate atropine resulotion 0.1 mg/kg, cephazolin-Na 0.3 g/kg and equal volume of normal saline with glucocorticoid at 30 min before operation. The donor surgery time, repairing liver time, recipient surgery time, anhepatic phase, and 1-day, 3-day and 7-day survival rates were compared between these two groups.
ResultsThe donor surgery time, repairing liver time, recipient surgery time, and anhepatic phase had no significant differences between the experimental group and control group (P>0.05), while the 1-day, 3-day and 7-day survival rates of the experimental group were significantly higher than those of the control group [96% (48/50) versus 80% (40/50), P<0.05; 92% (46/50) versus 72% (36/50), P<0.05; 90% (45/50) versus 54% (27/50), P<0.05].
ConclusionUsage of glucocorticoid might contribute to improve survival rate of rat liver transplantation model.
Objective To investigate the expression levels of osteoprotegerin (OPG) and receptor activator of NF-κB l igand (RANKL) mRNAs in bone tissues of the femoral head of the patients suffering glucocorticoid-induced osteonecrosisof the femoral head (ONFH), and to discuss the relationship between OPG/RANKL and ONFH. Methods Between March2007 and March 2008, bone tissues of the femoral head were collected as the experimental material from 35 patients suffering ONFH (experimental group) and from 21 patients suffering fracture of femoral neck (control group). The ratio of men to women in both groups was 4 ∶ 3, whose age was 41-70 years old (55.34 on average in the experimental group and 55.33 on average in the control group). The experimental group received over 3 weeks’ glucocorticoid treatment or more than 1 week’ s high-dose glucocorticoid treatment in recent 2 years, while the control group never received more than 1 week’s hormone treatment. In the two groups, the microstructure of bone tissues of the femoral head was detected by HE staining and the bone tissue total RNA was extracted, and then the expression levels of OPG mRNA and RANKL mRNA were examined by realtime quantitative PCR (RTQ-PCR) for each sample. Results HE staining: bone trabeculae and bone units were replaced by interrupted bone fragments, which were surrounded by many inflammatory granulation tissues and few osteocytes were seen in bone lacunae in the experimental group. In the control group, bone trabeculae and bone units were made by complete lamellar bones which surrounded blood vessels and osteocytes were seen in lacunae. RTQ-PCR testing: in the experimental group, OPG mRNA and RANKL mRNA were 1.35 ± 0.42 and 4.36 ± 1.35, respectively, while in the control group they were 1.78 ± 0.63 and 3.49 ± 1.02, respectively. The expression level of OPG mRNA in the experimental group was significantly lower than that in the control group, and the expression level of RANKL mRNA of the former was significantly higher than the latter. The OPG mRNA/ RANKL mRNA ratio in the xperiment group (0.34 ± 0.16) was significantly lower than that in the control group (0.54 ± 0.20), and there was significant difference (P lt; 0.05). Conclusion The glucocorticoid-induced ONFH may be related to the expression levels of OPG mRNA/RANKL mRNA in bone tissues.
ObjectiveTo study the perioperative treatment of total hip arthroplasty (THA) for avascular necrosis of the femoral head (ANFH) in systemic lupus erythematosus (SLE) patients.
MethodsThe clinical data of 27 patients with SLE and ANFH, who underwent 40 THAs between August 2009 and November 2012 were retrospectively analyzed. There were 5 male and 22 female patients, and the average age of the patients at surgery was 40 years ranging from 21 to 66 years. Fourteen cases had unilateral THA and 13 had bilateral THA. The combined disease included 2 cases of hypertension, 3 chronic bronchitis, 1 autoimmune liver disease and hypohepatia, 2 sicca syndrome, and 2 anemia.
ResultsAll the patients were stable peri-operatively. No patient had adrenal crisis. Four complications were noted, including one case of fever reaction (maximum temperature:39.3℃), 1 incision fat liquefaction, 1 pulmonary infection, and 1 early dislocation due to improper exercise on the 12th day after the operation. The patients were followed up for 24 to 53 months, and there was no deep infection, prosthetic loosening, peri-prosthetic fracture or deep vein thrombosis after THA.
ConclusionAlthough the incidence of postoperative complication is high in patients with SLE and ANFH undergoing THA, meticulous perioperative management can help these patients get through operation safely, including the use of glucocorticoid and antibiotics, treatment of osteoporosis, and prevention and treatment of complications.
ObjectiveTo compare and observe the fundus imaging characteristics of eyes with glucocorticoid-related central serous chorioretinopathy (CSC). MethodsA retrospective clinical study. A total of 149 CSC patients with 166 eyes diagnosed at Department of Ophthalmology of The First Affiliated Hospital of Zhengzhou University from March 2021 to October 2024 were included in the study. The duration of the disease from the appearance of symptoms to treatment was less than 3 months. All affected eyes underwent best-corrected visual acuity (BCVA), fundus color photography, swept-source optical coherence tomography (SS-OCT), and fundus fluorescein angiography (FFA) examinations. BCVA was tested using an international standard vision chart and converted into logarithm of the minimum angle of resolution (logMAR) visual acuity for statistical analysis. The SS-OCT instrument measured subfoveal choroidal thickness (SFCT), central macular thickness (CMT), choroidal vascular volume (CVV), and the width and height of flat irregular pigment epithelial detachment (FIPED). FIPED, subretinal fibrin, and choroidal layer strong reflective spots were identified from SS-OCTA B-scan images; multiple leakages (leak points >3) were identified from FFA images. Based on the presence or absence of a clear history of glucocorticoid administration before the onset, patients were divided into glucocorticoid-related and non-glucocorticoid-related groups, comprising 41 patients with 53 eyes and 108 patients with 113 eyes, respectively. Clinical and fundus imaging characteristics of the two groups were compared. The comparison of quantitative data between the two groups was performed using independent samples t test or non-parametric independent samples Wilcoxon test; the comparison of qualitative data was performed using χ2 test. ResultsCompared with the non-glucocorticoid-related group, the glucocorticoid-related group had a smaller male-to-female ratio and a higher bilateral incidence, and the differences were statistically significant (χ2=4.925, 17.849; P＜0.05). The logMAR BCVA for the glucocorticoid-related and non-glucocorticoid-related groups were 0.45±0.33 and 0.21±0.21, respectively; SFCT were (644.43±131.91) and (507.26±121.79) μm; CMT were (389.51±233.45) and (362.59±140.85) μm; CVV were (4.44±1.07) and (3.67±0.82) mm3; FIPED incidence were 58.49% (31/58) and 20.35% (23/113), respectively; FIPED width and height were (1 122.01±533.98) and (742.90±388.79) μm, and (99.13±92.17) and (33.01±15.99) μm; subretinal fibrin were observed in 24 (45.28%, 24/53) and 15 (13.27%, 15/113) eyes; choroidal strong reflections were found in 38 (71.70%, 38/53) and 45 (39.82%, 45/113) eyes; multiple leak points were identified in 35 (66.03%, 35/53) and 40 (35.40%, 40/113) eyes, respectively. Compared with the non-glucocorticoid-related group, the glucocorticoid-related group had worse BCVA (Z=?4.984), thicker SFCT (t=6.586), larger CVV (t=5.160), higher incidence of FIPED (χ2=23.908), and greater width and height of FIPED (t=2.895, Z=?3.703). The glucocorticoid-related group also had a significantly increased incidence of subretinal fibrin, choroidal strong reflections, and multiple leak points, with all differences being statistically significant (χ2=20.565, 14.663, 13.675; P＜0.05); however, the comparison of CMT showed no statistically significant difference (Z=?0.651, P＞0.05). ConclusionCompared with non-glucocorticoid-related CSC, glucocorticoid-related CSC patients have poorer vision, are more likely to affect both eyes, show no gender bias; choroidal vascular dilation is more significant, and damage to the outer retina and retinal pigment epithelium is more severe.
ObjectiveTo analyze the phasic changes of bone mass, bone turnover markers, and estrogen levels at different time points after glucocorticoid (GC) intervention in rat and their correlation.
MethodsThirty-four female 3-month-old Sprague Dawley rats were randomly divided into the following 3 groups:baseline group (n=6), dexamethasone (DXM) group (n=14), and control group (n=14). Rats were injected with DXM at the dose of 0.75 mg/kg, twice a week for 12 weeks in DXM group, with salt solution lavage in control group, and no treatment was given in baseline group. The body mass, adrenal weight, and uterus weight were measured. Bone mineral density (BMD), bone mineral content (BMC), and bone area (BA) of lumbar vertebral and femurs were detected by dual energy X-ray absorptiometry. Meanwhile, the serum levels of N-terminal propeptide of type I procollagen (PINP), C-terminal cross-linking telopeptide of type I collagen (β-CTX), and estrogen levels were determined by ELISA before experiment in baseline group and at 4, 8, and 12 weeks after experiment in control and DXM groups. At last, the correlation was analyzed among body weight, BMD, PINP, β-CTX, estrogen levels, and GC intervention duration of DXM group.
ResultsThe body mass, adrenal weight, and uterus weight in DXM group were significantly lower than those in baseline group and control group at all the time points (P<0.05). The levels of PINP and β-CTX elevated slowly in DXM group, significant difference was found at 12 weeks (P<0.05), but no significant difference at the 4 and 8 weeks (P>0.05) when compared with those in baseline group and control group. The estrogen level in DXM group was significantly lower than that in baseline group and control group at all the time points (P<0.05). BMD, BMC, and BA of lumbar vertebral and femurs in DXM group were significantly lower than those in control group at all the time points after GC intervention (P<0.05). Loss of bone mass of L2 and femoral trochanteric region in DXM group was the lowest of all ranges of interest (ROIs). BMC and BA of lumbar vertebrae and BA of femoral shaft in DXM group at 4 weeks were significantly lower than those in baseline group (P<0.05). But there was no significant difference in BMD, BMC, and BA of other lumbar vertebrae and femurs' ROIs between DXM group and baseline group at all the time points (P>0.05). After GC intervention, BMD of lumbar vertebrae and femurs had negative correlation with PINP and β-CTX (P<0.05) and positive correlation with estrogen level (P<0.05).
ConclusionThe bone mass decreases rapidly at the early stage after GC intervention and then maintains a low level with time, the levels of bone turnover markers show a progressive increase, and the estrogen levels show a decrease trend. In addition, body weight, the levels of bone turnover markers and estrogen are associated with the change of bone mass.
In recent years, with the development of neuroimaging and the improvement of people’s awareness, the incidence of cerebral venous sinus thrombosis (CVST) has been increasing year by year. CVST with venous infarction or haemorrhage is severe, accounting for about 60% of CVST, and its clinical manifestations are serious. The current therapies including anticoagulation and intravascular treatment have not significantly improved the prognosis of severe CVST patients. The incidence of long-term poor prognosis (modified Rankin scale score≥2) is up to 56.1%. Recent research indicates that inflammation may be an important factor leading to severe CVST and is significantly associated with poor prognosis. Anti-inflammatory treatment with glucocorticoids may provide a novel method for severe CVST, but further clinical studies are needed to verify it. This paper introduces the relationship between inflammation and severe CVST in order to explore the feasibility of glucocorticoid for severe CVST.
ObjectiveTo explore the clinical characteristics of idiopathic hypereosinophilic syndrome (IHES), and improve the early diagnosis and treatment of such diseases.MethodsThe clinical diagnosis and treatment data were retrospectively analyzed from the patients with confirmed IHES hospitalized in China-Japan Friendship Hospital between September 2010 to May 2018.ResultsFifteen patients were included. There were 3 women and 12 men in the study, with an average age of 53.7±21.3 years. Eleven patients had respiratory problems, with an average course of 7 months. Most lesions occurred in both lungs. Patchy distribution, ground glass opacity, pleural effusion and mediastinal lymph node enlargement were common in the chest computed tomography. Serum total IgE was significantly increased. Four patients had other systems involved rather than respiratory system. One of them had digestive problems and another 3 had skin diseases. There was a significant increase in eosinophils in peripheral blood, bone marrow and histopathology, the same as eosinophils in sputum, pleural effusion, and bronchoalveolar lavage fluid. Hypoxemia was common in patients with respiratory problems. The blood eosinophil and total IgE were reduced after glucocorticoid treatment, and the hypoxemia was significantly improved.ConclusionsThe clinical symptoms, signs and image of chest computed tomography are not specific in IHES, so the rate of misdiagnosis and wrong diagnosis is high. This disease involves many organs or systems, so the pathological examination should be completed as soon as possible to make a clear diagnosis to prevent further damage. Glucocorticoid treatment is effective in this disease.
Objective Glucocorticoid is the main cause of non-traumatic avascular necrosis of femoral head. To explore the changes of reactive oxygen species (ROS) in the bone microvascular endothel ial cells treated with glucocorticoid so as to investigate the pathogenesis of steroid-induced avascular necrosis of femoral head. Methods The cancellous bone of femoral head was harvested from voluntary donators undergoing total hip arthroplasty, and then the bone microvascular endothel ial cells were isolated by enzyme digestion. The cells at passage 3 were cocultured with different concentrations of hydrocortisone (0, 0.03, 0.10, 0.30, and 1.00 mg/mL) for 24 hours. MTT assay was used for the inhibitory rate of cell prol iferation, flow cytometry for apoptosis rate, and fluorescence probe for the production of ROS and xanthine oxidase (XOD). Results At 2-3 days primary culture, the cells were spindle and arranged l ike cobbles and they reached confluence after 1 week. The inhibitory rates of cell prol iferation in 0.03, 0.10, 0.30, and 1.00 mg/mL groups were 20.22% ± 2.97%, 22.94% ± 4.52%, 43.98% ± 3.35%, and 78.29% ± 3.85%, respectively; and 2 high-concentration groups (0.30 and 1.00 mg/mL groups) were significantly higher (P lt; 0.05) than 2 low-concentration groups (0.03 and 0.10 mg/mL groups). The apoptosis rates in 0, 0.03, 0.10, 0.30, and 1.00 mg/mL groups were 0.10% ± 0.01%, 0.23% ± 0.02%, 1.83% ± 0.04%, 6.34% ± 0.11%, and 15.33% ± 0.53%, respectively; 2 high-concentration groups (0.30 and 1.00 mg/mL groups) were significantly higher (P lt; 0.05) than 0 mg/mL group. In 0, 0.30, and 1.00 mg/ mL groups, the ROS levels were 57.35 ± 7.11, 120.47 ± 15.68, and 166.15 ± 11.57, respectively, and the XOD levels were 0.017 9 ± 0.000 9, 0.028 3 ± 0.001 7, and 0.067 7 ± 0.004 1, respectively; there were significant differences in the levels of ROS and XOD among 3 groups (P lt; 0.05). Conclusion Increasing of ROS production in bone microvascular endothel ial cells can be induced by high concentration glucocorticoid, and it can result in cell injury
