Anaphylaxis associated with intracavernous penile injection of prostaglandin E1 in combination with papaverine and phentolamine / Anafilaxia associada à injeção intracavernosa peniana de prostaglandina E1 em combinação com papaverina e fentolamina

Total radical prostatectomy for advanced prostate cancer may lead to sexual impotence, since it is associated with severe erectile dysfunction. A widely recommended treatment for this disabling condition is intracavernous penile injection of a mixture of prostaglandin E1, papaverine, and phentolamine. To our knowledge, we present the first case of anaphylaxis associated with intracavernous penile injection of prostaglandin E1 in combination with papaverine and phentolamine.

A prostatectomia radical total para câncer de próstata avançado pode levar à impotência sexual, associada a uma disfunção erétil grave. Um tratamento amplamente recomendado para esta condição incapacitante é a injeção intracavernosa no pênis de uma mistura de prostaglandina E1, papaverina e fentolamina. Até onde sabemos, estamos apresentando o primeiro caso de anafilaxia associada à injeção intracavernosa peniana de prostaglandina E1 em combinação com papaverina e fentolamina.

Histomorphometry evaluation of bone anabolism promoted by prostaglandin E1 and its relation to hypercalcemia / Evaluación histomorfométrica del anabolismo óseo en la reparación promovida por la prostaglandina E1 y su relación con la hipercalcemia

Abstract Background: At present, parathyroid hormone is the only existing anabolic bone therapy but produces hypercalcemia. Prostaglandin E1 (PGE1) has been suggested as a bone anabolic agent that allows bone modeling formation without producing hypercalcemia. This study aimed to corroborate these PGE1 properties. Methods: For 22 days, rabbits (n = 30) were divided into three groups (n = 10 each group) and received intravenous solutions: vehicle (control group), palate disjunction + vehicle (sham group), and palate disjunction + 50 mg of PGE1 (PGE1 group). On days 1, 3, and 22, palatine suture X-rays were taken. On day 22, bone formation markers were analyzed, and the rabbits were sacrificed. Bone palate undecalcified samples were processed. Histomorphometry software was used to analyze bone parameters, and the mineralization front was stained with toluidine blue. Scalloped lines reflect remodeling-based bone formation (RBF), and smooth lines reflect modeling-based formation (MBF). Results: X-rays showed more significant palatal disjunction in the PGE1 group; this group exhibited significant calcitriol serum increments. Hypercalciuria was observed in the PGE1 group, and resorption markers (N-telopeptides) remained stable. Sutural bones in the PGE1 group exhibited significant anabolism in structural parameters. RBF was 20%, and MBF was 6% in the sham group; in the PGE1 group, RBF was 8.6%, and MBF was 17%. In the PGE1 group, mineralization was significantly accelerated, but resorption remained stable. Conclusions: This model suggests that PGE1 favors palate disjunction, calcitriol synthesis, and shortens the mineralization. Therefore, PGE1 is an important bone anabolic molecule predominantly of modeling-based form and no hypercalcemia.

Resumen Introducción: La hormona paratiroidea es la única molécula anabólica ósea, pero ocasiona hipercalcemia. La prostaglandina E1 (PGE1) sugiere ser un anabólico óseo con formación por modelación predominante y generalmente no ocasiona hipercalcemia. El objetivo de este estudio fue corroborar estas propiedades de la PGE1. Métodos: Por 22 días, 30 conejos divididos en tres grupos (n = 10 cada grupo) recibieron una solución por vía intravenosa: vehículo (grupo control), disyunción palatina más vehículo (grupo sham) y disyunción palatina más 50 mg de PGE1 (grupo PGE1). A los días 1, 3 y 22 se obtuvieron radiografías de la sutura palatina. En el día 22 se analizaron los marcadores bioquímicos de formación ósea y se sacrificó a los conejos. Las suturas y los huesos suturales se procesaron sin descalcificar. La evaluación histomorfométrica fue digitalizada y el frente de mineralización ósea se tiñó con azul de toluidina. Las líneas irregulares reflejan resorción (remodelación) y las líneas rectas no resorción (modelación). Resultados: Radiográficamente, la disyunción palatina fue mayor en el grupo PGE1. Este grupo mostró una hipercalcitonemia significativa, pero la calcemia y los marcadores resortivos (N-telopéptidos) se mantuvieron estables. Por histomorfometría, los huesos suturales del grupo PGE1 mostraron anabolismo significativo en parámetros estructurales. En el grupo sham, la remodelación ósea fue del 20% y la modelación fue del 6%; en el grupo PGE1, la remodelación fue del 8.6% y la modelación fue del 17%. En este mismo grupo, la mineralización fue significativamente acelerada, pero la resorción se mantuvo igual. Conclusiones: Este modelo sugiere que la PGE1 favorece la disyunción palatina y el aumento del calcitriol, y acelera la mineralización y el anabolismo óseo por modelación predominante sin hipercalcemia.

Changes in the proliferation and angiogenesis of human dental pulp stem cells after treated with prostaglandin E1 combined with basic fibroblast growth factor / 中国组织工程研究

BACKGROUND: Prostaglandin E1 and basic fibroblast growth factor can promote the proliferation of human dental pulp stem cells, but the effects of their combinations on the proliferation of human dental pulp stem cells and angiogenesis are unknown. OBJECTIVE: To investigate the effects of prostaglandin E1 combined with basic fibroblast growth factor on the proliferation and angiogenesis of human dental pulp stem cells. METHODS: (1) Human dental pulp stem cells were isolated and cultured in vitro. After detection and identification of surface markers, prostaglandin E1 and basic fibroblast growth factor at concentrations of 5, 10, 20, 50 and 100 μg/L were used to treat human dental pulp stem cells in vitro. The untreated cells served as control group. The cell proliferation was detected by cell counting kit-8 assay, and the optimum drug concentration and time of drug action were screened. (2) The in vitro cultured human dental pulp stem cells were divided into four groups: blank control group, prostaglandin E1 group, basic fibroblast growth factor group and combination group. The cell proliferation was detected by cell counting kit-8 assay. Human dental pulp stem cell conditioned medium was extracted. The levels of vascular endothelial growth factor and endostatin in the culture medium were detected by ELISA. The in vitro tubular formation ability of human umbilical vein endothelial cells after culture in conditioned medium was tested by tubule formation experiment. RESULTS AND CONCLUSION: The optimum concentration of prostaglandin E1 and basic fibroblast growth factor was 20 μg/L, and the optimum time of action was 2 days. Compared with the blank control group, the relative proliferation rate, level of vascular endothelial growth factor and the angiogenesis ability of human umbilical vein endothelial cell in vitro in the prostaglandin E1, basic fibroblast growth factor and combination groups were significantly increased (P < 0.05), while the level of endostatin was significantly decreased (P < 0.05). All above index levels in the combination group were significantly superior to those in the prostaglandin E1 and basic fibroblast growth factor groups (P < 0.05). In summary, prostaglandin E1 combined with basic fibroblast growth factor can promote the proliferation of human dental pulp stem cells and enhance the tubular formation ability of human umbilical vein endothelial cells in vitro.

Objective To explore the effects of prostaglandin E1 (PGE1) on the expression of Apaf-1 and TLR4 in rats with cerebral ischemia-reperfusion(CIR) injury.Methods 32 healthy adult male Wistar rats were randomly divided into four groups,which were sham operated group (n=8),CIR model group (n=8) and PGE1 pretreated groups (low dose,12 μg · kg-1;high dose,24 μg · kg-1,n =8).Rat model of cerebral ischemia/reperfusion was established by bilateral common carotid artery ligation.The expression of Apaf-1 and TLR4 was detected with immunohistochemical staining method in hippocampus and epencephalon.Results After 20 min of ischemia and reperfusion for 24 h,compared with sham operated group (Apaf-1:hippocampus (0.87±0.78),epencephalon (0.67 ±0.43);TLR4:hippocampus (2.43 ± 1.17),epencephalon (1.97± 1.033)),the number of positive cells of Apaf-1 (hippocampus (11.83± 2.26);epencephalon(5.80±1.30) and TLR4 (hippocampus(16.90±2.86);epencephalon(12.90±2.66)) was increased in CIR model group (P＜0.05).Compared with CIR model group,the positive cell numbers of Apaf-1 (hippocampus:low dose(9.83±2.12),high dose(5.50± 1.17);epencephalon:low dose(4.87± 1.38),high dose(2.73±1.172)) and TLR4 (hippocampus:low dose (11.53± 2.40),high dose (9.13 ± 2.54);epencephalon:low dose (9.07 ± 2.07),high dose (4.47 ± 1.68)) were reduced dose-dependently in PGE 1 pretreatment all group (all P ＜0.05).Conclusion PGE1 can inhibit the expression of Apaf-1 and TLR4 in hippocampus and epencephalon of rat with cerebral ischemia-reperfusion injury.

Ischemic preconditioning vs adenosine vs prostaglandin E1 for protection against liver ischemia/reperfusion injury

Ischemia/reperfusion injury is still a major cause of morbidity and mortality during liver surgery and transplantation. A variety of surgical and pharmacological therapeutic strategies have been investigated to minimize the effects of ischemia/reperfusion. The aim of our study was to analyze and compare preventive influences of ischemic preconditioning, adenosine and prostaglandin E1 in the experimental model of hepatic ischemia/reperfusion injury. Adult chinchilla rabbits were divided into four groups: 10 rabbits subjected to liver ischemic preconditioning (3-min period of inflow occlusion followed by a 5-min period of reperfusion) followed by 45 min of Pringle maneuver; 10 rabbits subjected to pre-treatment with intraportal injection of adenosine followed by 45 min of Pringle maneuver; 10 rabbits subjected to pre-treatment with intraportal injection of prostaglandin E1 followed by 45 min of Pringle maneuver; and control group of 10 rabbits subjected to 45 min of inflow liver ischemia without any preconditioning. On the second postoperative day, blood samples were obtained and biochemical parameters of liver function were measured and compared. Liver tissue samples were also obtained and histopathological changes were compared. Based on biochemical and histopathological parameters, it was demonstrated that ischemic preconditioning provided the best protection against hepatic ischemia/reperfusion injury. This was probably due to a wider range of mechanisms of action of this method oriented to reduce oxidative stress and inflammation, and restore liver microcirculation and hepatocyte energy compared to the examined pharmacological strategies.

Therapeutic effect of prostaglandin E1 in monocrotaline-induced pulmonary arterial hypertension rats / 대한해부학회지

Pulmonary arterial hypertension (PAH) is a severe pulmonary vascular disease characterized by sustained increase in pulmonary arterial pressure and excessive thickening and remodeling of distal small pulmonary arteries. During disease progression, PAH include increase in mean pulmonary arterial pressure, right ventricular (RV) enlargement, increased pulmonary vascular resistance, and smooth muscle hypertrophy in pulmonary arterioles. Several anti-PAH therapies targeting various pathways involved in PAH progression have been approved by the Food and Drug Adminstration. However, many of the currently available anti-PAH drugs suffer from a number of limitations, including short biological half-life, and poor pulmonary selectivity. Prostaglandin E1 (PGE1) is a potent vasodilator with selectivity toward pulmonary circulation when it is administered via the pulmonary route. However, PGE1 has a very short half-life of 5–10 minutes. Therefore, we hypothesized that long-term effect of PGE1 could reduce mal-adaptive structural remodeling of the lung and heart and prevent ventricular arrhythmias in monocrotaline-induced rat model of PAH. Our results revealed that PGE1 reduced ventricular hypertrophy, protein expressions of endothelin-1 and endothelin receptor A, and the expression of fibrosis. These results support the notion that PGE1 can improve the functional properties of RV, highlighting its potential benefits for heart and lung impairment.

Effect of Prostaglandin E1 Combined with Atorvastatin on Related Indicators in Elderly Patients with Hyper-tensive Nephropathy / 中国药房

OBJECTIVE:To investigate the effect of prostaglandin E1 combined with atorvastatin on related indicators in elderly patients with hypertensive nephropathy. METHODS:70 elderly patients with hypertensive nephropathy were randomly divided into control group and observation group. Control group was orally given 10 mg Atorvastatin calcium tablet,once a day;observation group was additionally given 10 μg Prostaglandin E1 injection,adding into 250 ml 0.9% Sodium chloride injection by intravenous infusion,once a day. The treatment course for both groups was 2 weeks. All patients were given quality low-protein,low-salt and low cholesterol diet,depressurization,lipid-lowering and other conventional treatment. Heart rate (HR),systolic blood pressure (SBP),diastolic blood pressure(DBP),triglyceride(TG),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C),serum creatinine(Scr),24h urinary protein(TP/24 h),microalbuminuria(mAlb),uri-nary β2-microglobulin (β2-MG),blood urea nitrogen (BUN) before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:After treatment,HR,SBP,DBP,TG,TC and LDL-C in 2 groups were significantly lower than before,and difference was statistically significant(P0.05);Scr,TP/24 h,mAlb,β2-MG and BUN were signifi-cantly lower than before,and observation group was lower than control group,the differences were statistically significant(P0.05). CONCLUSIONS:Based on the con-ventional treatment,prostaglandin E1 combined with atorvastatin can effectively improve the HR,blood pressure and blood lipid of elderly patients with hypertensive nephropathy;however,prostaglandin E1 combined with atorvastatin is better than atorvastatin alone in aspect of protecting renal function,with similar safety.

OBJECTIVE:To systematically evaluate the efficacy and safety of prostaglandin E1 combined with hydration for the prevention of contrast-induced nephropathy(CIN)and provide evidence-based reference for the clinical treatment. METHODS:The PubMed,Medline (Ovid),EMbase (Ovid),Cochrane Library,VIP,CJFD and WanFang database were retrieved to collect the randomized controlled trails(RCT)of prostaglandin E1 combined with hydration for the prevention of CIN. After information collec-tion and methodology quality evaluation,the Meta-analysis was performed using Rev Man 5.3 software. RESULTS:12 RCTs involv-ing 1 732 patients were included. The results of Meta-analysis showed that the incidence of CIN in test group was significantly low-er than control group[RR=0.40,95%CI(0.30,0.53),P<0.001],the incidence of phlebitis was higher than control group [RR=10.18,95%CI(1.37,75.67),P=0.02] and there was no significant difference in the need rate of renal replacement between test group and control group[RR=0.44,95%CI(0.12,1.61),P=0.21]. CONCLUSIONS:Intravenous prostaglandin E1 combined with hydration can effectively reduce the incidence of CIN. Occurance of phlebitis should be paid attention to. Due to the limited quality and sample of included studies,it remains to be further verified by high-quality and large-sample RCT.

Salvage Therapy from Traumatic Ischemic Finger Necrosis via Prostaglandin E1 Assisted Conservative Treatment: A Case Report

Prostaglandin E1 (PGE-1) is a potent vasodilator, which also inhibits platelet aggregation, affects the blood flow viscosity, and fibrinolysis. The compound also excerts anti-inflammatory effects by inhibiting the monocyte and neutrophil function. PGE-1 has been widely administered following microvascular flap surgery, along with perioperative antithrombotic agents such as low molecular weight heparin or aspirin, showing excellent results. We report a case showing successful salvage recovery from post-traumatic ischemic necrosis of the finger via PGE-1 assisted conservative treatment.

Effect of prostaglandin E1 versus corticotomy on orthodontic tooth movement: An in vivo study.

Background and Aim: The aim of the present study is to compare the effect of corticotomy versus prostaglandin E1 injection in human subjects on rate of tooth movement, anchorage loss and their effect on crest bone height and root length. Settings and Design: Clinical interventional study. Split mouth design was used. Materials and Methods: Study was done on 32 regular orthodontic patients. A volume of 100 mcg of prostaglandin E1 was injected on the right side once in 2 weeks and on the left side corticotomy was performed, and canine retraction was started on both sides simultaneously. The rate of space closure and anchorage loss was assessed with casts. The root length and crestal bone height changes were assed with IOPAs. The comparison of rate of tooth movement, anchorage loss, crestal bone height and root length changes between the sides were statistically analyzed using paired t‑test. Results: The average rate of space closure on right side was 0.36 mm/week with a standard deviation of 0.05 mm/week and on the left side average rate of space closure was 0.40 mm/week with a standard deviation of 0.04 mm/week. The difference between the rate of closure between the right side and left where found to be statistically significant (P = 0.003). The anchorage loss, the crestal bone height changes and root length changes were not statistically significant. Conclusion: The rate of tooth movement was significantly more with corticotomies when compared with given dose of prostaglandin injection.

Effect of prostaglandin E1 lipid microsphere on cardiac haemodynamics and oxygen metabolism during the perioperative period in the infants with ventricular septal defect and severe pulmonary artery hypertension / 中华实用儿科临床杂志

Objective To measure the effect of prostaglandin E1 (PGE1) lipid microsphere on cardiac haemodynamics and oxygen metabolism during the perioperative period in the infants with ventricular septal defect(VSD)and severe pulmonary artery hypertension (PAH).Methods Forty infants [(7.1 ± 3.3) years old] with VSD and severe PAH who underwent surgery under cardiopulmonary bypass were involved in the study.They were divided into 2 groups averagely:control group (20 cases) and experimental group (20 cases).All the patients were continuously intravenous pumping of nitroglycerin or PGE1 during the perioperative period.The effect of PGE1 on cardiac haemodynamics and oxygen metabolism between the 2 groups were measured during 72 hours postoperatively.Results The statistical analysis demonstrated that the values trend of mean arterial blood pressure (mABP),mean pulmonary arterial pressure (mPAP),mPAP/mABP,pulmonary vascular resistance index (PVRI),left ventricular stroke work index (LVSWI) were affected during 72 h postoperative period (P ＜0.05).The mABP at 48 h,LVSWI at 48 h,72 h in experimental group were significantly higher than those in control group (all P ＜0.05).The mPAP at 8 h,48 h,PVRI at 72 h and pulmonary arterial wedge pressure (PAWP)at 12-48 h in experimental group were significantly lower than that in control group (all P ＜ 0.05).Compared to postoperative period,mABP at 12 h,72 h,mPAP at 4-12 h,48 h were increased significantly in control group (P ＜ 0.05) ; mABP and LVSWI at 8-72 h,right ventricular stroke work index at 48 h,72 h and cardiac index at 72 h were significantly increased (P ＜0.05),while PVRI and PAWP at 72 h,mPAP/mABP at 24-72 h were significantly decreased in experimental group (P ＜ 0.05).There were no significant differences in the values of oxygen metabolism between both groups (P ＞0.05).Conclusions LipoPGE1 can significantly decrease the pulmonary arterial pressure,which can enhance cardiac function and decrease the duration of intubation after surgery.
