    Experimental Efficacy of Pericardial Instillation of Anti-inflammatory Agents during Percutaneous Epicardial Catheter Ablation to Prevent Postprocedure Pericarditis

    JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 11 2007
    ANDRE D'AVILA M.D.
    Introduction: Pericarditis is a potential complication of catheter-based percutaneous epicardial mapping and ablation. This study evaluates the efficacy and safety of intrapericardial instillation of anti-inflammatory agents after pericardial mapping and ablation in a porcine model of postprocedural pericarditis. Methods and Results: Twenty-five healthy swine underwent epicardial mapping and ablation after transthoracic subxyphoid puncture. After 60 minutes of continuous catheter manipulation in the pericardial space, radiofrequency energy was delivered in a linear fashion to the epicardial surfaces of both atria. The animals were randomly divided to receive the anti-inflammatory agents, Hyaluronic Acid and Triamcinolone, or control. Fourteen days after ablation, the hearts were excised and the degree of pericardial reaction/adhesions scored. The severity was uniformly graded 4 (intense) in all control animals and was characterized by intense adhesion between the parietal and the visceral pericardium obscuring tissue planes and epicardial anatomy. Hyaluronic Acid provided a mild benefit (score 3.0 ± 0.9), but 2 mg/kg of Triamcinolone significantly attenuated the inflammatory effect (all animals uniformly scored 1.0). Conclusion: In a porcine model of ablation-related pericarditis, intrapericardial instillation of 2 mg/kg of intermediate-acting corticosteroids effectively prevents post-procedure inflammatory adhesion formation.

    Clinical trial: a randomized trial comparing fluoroscopy guided percutaneous technique vs. endoscopic ultrasound guided technique of coeliac plexus block for treatment of pain in chronic pancreatitis

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 9 2009
    D. SANTOSH
    Summary Background, Coeliac plexus block (CPB) is a management option for pain control in chronic pancreatitis. CPB is conventionally performed by percutaneous technique with fluoroscopic guidance (PCFG). Endoscopic ultrasound (EUS) is increasingly used for CPB as it offers a better visualization of the plexus. There are limited data comparing the two modalities. Aim, To compare the pain relief in chronic pancreatitis among patients undergoing CPB either by PCFG technique or by EUS guided technique. Methods, Chronic pancreatitis patients with abdominal pain requiring daily analgesics for more than 4 weeks were included. Fifty six consecutive patients (41 males, 15 females) participated in the study. EUSG-CPB was performed in 27 and PCFG-CPB in 29 patients. In both the groups, 10 mL of Bupivacaine (0.25%) and 3 mL of Triamcinolone (40 mg) were given on both sides of the coeliac artery through separate punctures. Results, Pre and post procedure pain scores were obtained using a 0-10 visual analogue scale. Improvement in pain scores was seen in 70% of subjects undergoing EUS-CPB and 30% in Percutaneous- block group (P = 0.044). Conclusions, EUS-guided coeliac block appears to be better than PCFG-CPB for controlling abdominal pain in patients with chronic pancreatitis. [source]


    In Vitro Phototoxic Properties of Triamcinolone 16,17-acetonide and Its Main Photoproducts,

    PHOTOCHEMISTRY & PHOTOBIOLOGY, Issue 5 2003
    Giorgia Miolo
    ABSTRACT The phototoxicity of triamcinolone 16,17-acetonide has been estimated through a panel of,in vitro tests. The main target involved in phototoxicity induced by triamcinolone appeared to be the cell membrane. Oxygen-independent photohemolysis was observed. A photochemical study in water and buffered solutions supported the conclusion that this is related to the action of radicals formed upon UV irradiation (in particular UV-B) by Norrish Type-I fragmentation of the C-20 ketone group. Peroxy radicals were formed in the presence of oxygen and were the active species in that case. Three photoproducts, isolated from the photodegradation of the drug, were submitted to the same toxicity tests. Two of them were proved to possess toxic or phototoxic properties on erythrocytes, primarily induced by UV-B light, and may participate in the photosensitizing activity of triamcinolone 16,17-acetonide. Our in vitro results suggest that the drug can elicit weak photosensitizing properties in vivo. [source]


    Suspected allergy to local anaesthetics: follow-up in 135 cases

    ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 5 2010
    T. HARBOE
    Background: Local anaesthetics (LA) are generally considered safe with respect to allergy. However, various clinical reactions steadily occur. Even though most reactions are manifestations of reflexes to perceptive stimuli, uncertainty often remains regarding a possible allergic mechanism. This uncertainty later leads to an avoidance of local anaesthesia and unnecessarily painful interventions, resource-consuming general anaesthesia or even the risk of re-exposure to other yet unidentified allergens. In the present study, follow-up procedures at an allergy clinic were analysed to examine the frequency of identified causative agents and pathogenetic mechanisms and evaluate the strength of the diagnostic conclusions. Method: The medical records of 135 cases with alleged allergic reactions to LA were reviewed. Diagnoses were based on case histories, skin tests, subcutaneous challenge tests and in vitro IgE analyses. Results: Two events (1.5%) were diagnosed as hypersensitivity to LA, articaine,adrenaline and tetracaine,adrenaline, respectively. Ten reactions (7%) were diagnosed as IgE-mediated allergy to other substances including chlorhexidine, latex, triamcinolone and possibly hexaminolevulinate. As challenge testing was not consistently performed with the culprit LA compound, follow-ups were short of definitely refuting hypersensitivity in 61% of the cases. The reported clinical manifestations were in general diagnostically unspecific, but itch and generalised urticaria were most frequent in test-positive cases. Conclusion: Reactions during local anaesthesia are rarely found to be an IgE-mediated LA allergy. Whenever the clinical picture is compatible with allergy, other allergens should also be tested.

    Riga,Fede disease: association with microcephaly

    INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 6 2002
    Z. D. Baghdadi
    Summary. A case of microcephaly associated with traumatic ulceration to the ventral surface of the tongue (Riga-Fede disease) in a 12-month-old female is presented. To the best of our knowledge, such association has not been described previously. A conservative treatment regime was used, involving medical management, elimination of the sharp edges of the teeth and use of topical triamcinolone, and the ulceration healed over a period of 4 weeks.

    MMP-mediated collagen breakdown induced by activated protein C in equine cartilage is reduced by corticosteroids

    JOURNAL OF ORTHOPAEDIC RESEARCH, Issue 3 2010
    Elaine R. Garvican
    Abstract The plasma serine protease activated protein C (APC) is synthesized by human chondrocytes at sites of pathological cartilage fibrillation. APC levels are increased in osteoarthritis (OA) synovial fluid, and in vitro APC has been shown to synergize with interleukin-1, (IL-1) to promote degradation from ovine cartilage. A model of equine cartilage degradation was established and used to explore corticosteroid activities. Intraarticular corticosteroids are a commonly prescribed treatment for joint disease, however their role in disease modification remains unclear. APC synergized with IL-1 or tumor necrosis factor-, (TNF,), promoting significant collagen degradation from equine cartilage explants within 4 days, but did not augment glycoaminoglycan (GAG) release. APC activated pro-matrix metalloproteinases (MMP)-2 but not pro-MMP-9, as assessed by gelatin zymography. APC did not directly activate pro-MMP-13. Dexamethasone, triamcinolone, and methylprednisolone acetate (MPA) were evaluated at concentrations between 10, 5M and 10,10M. High concentrations significantly increased GAG release from IL-1+APC,treated explants. With the exception of MPA at 10,10M, all concentrations of corticosteroids caused significant decreases in IL-1+APC-driven hydroxyproline loss. Treatment with corticosteroids suppressed expression of MMP-1, -3, and -13 mRNA. The collagenolysis associated with IL-1+APC synergy, and the inhibition of this effect by corticosteroids may involve gelatinase activation and downregulation of MMP expression, respectively. © 2009 Orthopaedic Research Society.

    Modulation of the atopy patch test: tacrolimus 0.1% compared with triamcinolone acetonide 0.1%

    ALLERGY, Issue 5 2006
    J. M. Oldhoff
    Background:, The atopy patch test (APT) is an in vivo model to study the induction of eczema by inhalant allergens in atopic dermatitis patients. We studied the effect of pretreatment with topical tacrolimus 0.1% on APT in nonlesional skin of patients with atopic dermatitis. Methods:, Nonlesional skin of the back of patients with atopic dermatitis (n = 8) was treated once daily for 3 weeks with tacrolimus 0.1% ointment. Cetomacrogol ointment (placebo) was used as a negative control and triamcinolone acetonide 0.1% ointment as positive control. Twenty-four hours after the last APT application, samples were taken from the three treated areas (t = 0 and 24 h) for immunohistochemical analysis. Results:, Pretreatment with tacrolimus ointment did not suppress nonlesional skin infiltrate, in contrast to triamcinolone acetonide. Furthermore, tacrolimus did not inhibit the induction of the APT macroscopically (t = 24 h). An equal influx of T cells, eosinophils, dendritic cells, CD64+ and Fc,RI-positive cells was present compared with placebo. Only CD36+ and CD68-positive cells were inhibited compared with placebo. All cell types were significantly inhibited in triamcinolone acetonide-treated sites compared with placebo. Conclusions:, Pretreatment with tacrolimus 0.1% ointment does not inhibit the APT reaction in patients with atopic dermatitis. [source]


    Levator ani trigger point injections: An underutilized treatment for chronic pelvic pain,

    NEUROUROLOGY AND URODYNAMICS, Issue 1 2007
    Carolyn F. Langford
    Abstract Aims We conducted this study to examine the role of trigger point injections in females with chronic pelvic pain (CPP) of at least 6 months duration and specific levator ani trigger points. Methods This prospective study included 18 consecutive female patients with CPP and specific palpable levator ani trigger points. Pain was evaluated before and after trigger point injection on a Visual Analog Scale (VAS). Patient global satisfaction (PGS) and cure rates (PGC) were also measured by a VAS on a scale of 0,100%. The trigger points were identified manually by intravaginal palpation of the levator ani bilaterally. A mixture of 10 cc of 0.25% bupivacaine, 10 cc of 2% lidocaine and 1 cc (40 mg) of triamcinolone was used for injection of 5 cc per trigger point. A 5.5, Iowa trumpet pudendal needle guide was used for injection. All but one injection were performed in the office setting without sedation. Pelvic floor muscle exercises were taught for use after injection. Success was defined as a decrease in pain as measured by a VAS of 50% or more, as well as PGS and PGC scores of 60% or greater. There was a mean follow up of 3 months after trigger point injection. Results Thirteen of 18 women improved with the first trigger point injection resulting in a comprehensive success rate of 72%. Six (33%) of 18 women were completely pain free. Conclusion In the management of CPP, a non-surgical office-based therapy such as trigger point injections can be effective in selected patients.

    Exhaled nitric oxide after a single dose of intramuscular triamcinolone in children with difficult to control asthma

    PEDIATRIC PULMONOLOGY, Issue 7 2007
    Jayachandran R Panickar MRCPCH
    Abstract In a previous study, we reported that intramuscular (IM) triamcinolone improves symptoms in children with difficult asthma. In 2005, we revised our difficult asthma protocol to include assessment of airway inflammation, both directly using sputum induction and indirectly by measurement of exhaled nitric oxide (eNO). In this retrospective review, we aimed to describe (i) the changes in eNO and symptoms after a single 60 mg dose of IM triamcinolone and (ii) the changes in inflammatory markers in the subgroup with non-eosinophilic asthma (i.e., an induced sputum eosinophil differential count <2.0%). Seven children received IM triamcinolone during the study period. In all children, symptom scores fell in the week following the IM injection (P,<,0.01 vs. the pre-treatment week), and remained reduced for up to 6 weeks. eNO also fell within a week after IM therapy (P,<,0.01), and remained reduced for up to 4 weeks. Non-eosinophilic asthma was definitively identified in three children, and in this group, eNO and symptoms fell after the IM injection. We conclude that IM triamcinolone therapy reduces both eNO and symptoms for up to 4 weeks in children with difficult asthma. Our data provide preliminary evidence that IM triamcinolone is an effective anti-inflammatory therapy in children with induced sputum non-eosinophilic asthma.

    Management of recurrent anastomotic stenosis following radical prostatectomy using holmium laser and steroid injection

    BJU INTERNATIONAL, Issue 7 2008
    Ehab Eltahawy
    OBJECTIVE To present our experience with the management of recurrent and resistant anastomotic stenosis following radical prostatectomy (RP) using transurethral laser incision of the stenotic area and injection of steroids. PATIENTS AND METHODS Between January 1999 and April 2006, we evaluated 24 patients with anastomotic stenosis that would not allow the passage of the flexible cystoscope (17 F). Using the paediatric 7.5 F Olympus scope and a 550-µm fibre holmium laser, deep incisions were cut at the 3 and 9 o'clock positions at the bladder neck, and then triamcinolone was injected at the incision sites. Another session was then scheduled for office cystoscopy 6 weeks later, and if that showed evidence of annularity, another incision was made, as described above. RESULTS All 24 patients had RP for localized disease, 21 were retropubic and two were perineal, and one laparoscopic. Five patients had adjuvant radiotherapy. The mean patient age was 64 years. Nineteen (79%) patients had previous attempts to open the bladder neck: eight patients had dilatation, eight patients had internal urethrotomy, five patients underwent transurethral resection of the bladder neck, and six patients had open surgical intervention. The procedure was done once in 17 patients, and twice in seven patients. After a mean (range) follow up of 24 (6,72) months, 19 patients (83%) had a well-healed and widely patent bladder neck. Of the 24 patients, 17 had urinary incontinence (UI) associated with the bladder neck contracture. An artificial urinary sphincter was implanted in 11 patients, three of which had to be explanted for malfunction in two, and erosion in one. CONCLUSION Holmium laser bladder neck incision and steroid injection for anastomotic stenosis after RP had a success rate of 83% in this small series. It can be used safely as a primary treatment, or in some cases, for resistant and recurrent stenosis. It appears that insertion of an artificial sphincter can be done in patients with UI when the bladder neck remains patent for at least 8 weeks. [source]


    Combined intravitreal bevacizumab and triamcinolone in exudative age-related macular degeneration

    Jost B. Jonas
    Acta Ophthalmol. 2010: 88: 630,634 Abstract. Purpose:, We report on the combined application of intravitreal bevacizumab and triamcinolone acetonide for treatment of exudative age-related macular degeneration (AMD). Methods:, The clinical interventional case-series study included 16 patients (16 eyes) with exudative AMD who had previously received 3.5 ± 1.8 mono-injections of bevacizumab (1.5 mg) without significant improvement in visual acuity (VA) or reduction in macular exudation. All patients underwent a combined intravitreal injection of bevacizumab (1.5 mg) and triamcinolone acetonide (about 20 mg). Main outcome measures were VA and macular thickness as determined by optical coherence tomography. All patients were re-examined at 2,3 months after the intervention. Results:, Visual acuity improved significantly (p = 0.03) from 0.80 ± 0.40 logMAR prior to the combined injection to 0.65 ± 0.42 logMAR at 3 months after the injection. An improvement of , 1 Snellen line was found in eight subjects, an increase of , 2 lines in five subjects, and an improvement of , 3 lines in two subjects. One patient lost 1 line and one patient lost 3 lines. Central retinal thickness decreased significantly from 272 ± 62 ,m to 220 ± 47 ,m (p = 0.03). At the 6-month follow-up examination, central retinal thickness had increased again to 319 ± 142 ,m, which was not significantly (p = 0.30) different from baseline measurements. Conclusions:, The combined intravitreal application of bevacizumab and triamcinolone may temporarily be helpful in the treatment of exudative AMD if previous intravitreal bevacizumab mono-injections have failed to improve vision and reduce macular oedema.

    3412: Anti-VEGF and corticosteroids therapy in macular edema secondary to venous occlusions

    ACTA OPHTHALMOLOGICA, Issue 2010
    JAC POURNARAS
    Purpose To assess the evidence on interventions to improve visual acuity (VA) and to treat macular edema (ME) secondary to central (CRVO) and branch retinal vein occlusion (BRVO) Methods Recent randomized studies have evaluated the safety and efficacy of corticosteroids (triamcinolone, dexamethasone) and anti-VEGF therapies (ranibizumab). Score study evaluates preservative-free intravitreal triamcinolone with standard care in BRVO and CRVO. In Geneva study, dexamethasone (DEX) intravitreal implant is compared with sham in BRVO and CRVO. BRAVO and Cruise studies evaluate intraocular injections of ranibizumab in patients with ME following BRVO and CRVO, respectively. Results In SCORE study, there was no difference identified in visual acuity at 12 months for the standard care group compared with the triamcinolone groups in BRVO patients. Intravitreal triamcinolone is superior to observation for treating vision loss associated with ME secondary to CRVO. Improvements in BCVA with DEX implant were seen in patients with BRVO and CRVO, although the patterns of response differed. Intraocular injections of 0.3 mg or 0.5 mg ranibizumab provided rapid, effective treatment for ME following BRVO and CRVO Conclusion Grid photocoagulation remains the standard care for patients with vision loss associated with ME secondary to BRVO. Intravitreal triamcinolone is superior to observation for treating vision loss associated with ME secondary to CRVO. Dexamethasone intravitreal implant can both reduce the risk of vision loss and improve the speed and incidence of visual improvement in eyes with ME secondary to BRVO or CRVO. Anti-VEGF therapies represent new therapeutical option in the treatment of ME secondary to BRVO and CRVO. Further randomized studies are needed [source]


    Long-term study of vascular perfusion effects following arteriovenous sheathotomy for branch retinal vein occlusion

    ACTA OPHTHALMOLOGICA, Issue 3 2010
    Mahiul M. K. Muqit
    Abstract. Purpose:, To evaluate the perfusion effects and long-term visual outcome of pars plana vitrectomy (PPV) combined with arteriovenous sheathotomy (AVS) with or without triamcinolone for nonischaemic branch retinal vein occlusion (NI-BRVO). Methods:, Prospective, interventional case series of eight patients with NI-BRVO and haemorrhagic macular oedema. Patients underwent PPV and AVS (n = 5), or PPV, AVS and intravitreal triamcinolone (IVT, n = 3). A masked grading technique assessed fundus photographs and fluorescein angiography (FFA) following surgery. Scanning laser ophthalmoscopy/optical coherence tomography (SLO/OCT) evaluated macular oedema and outer retinal architecture. Main outcomes examined included visual acuity (VA), retinal reperfusion, collateral vessel regression, vascular dilatation, cystoid macular oedema (CMO), and ocular neovascularization. Results:, Seven of eight patients underwent uncomplicated surgery, with increased intraretinal perfusion and reduced engorgement of distal retinal veins. The mean pre-logMAR VA was 0.8 (SD 0.17) and did not improve significantly after surgery (post-logMAR 0.6, SD 0.38; p = 0.11, paired t -test). SLO/OCT showed persistent CMO in four patients, and subfoveal thinning of the photoreceptor layer. Collateral vessels disappeared at the blockage site post-AVS in 7/8 eyes, and this was associated with improved retinal perfusion. Six of eight patients developed epiretinal membrane. No patients developed ocular neovascularization. The average follow-up was 34.5 months. Conclusions:, PPV with AVS is a safe procedure, and adjunctive IVT had no additional effects on vascular perfusion. Successful decompressive surgery was followed by disappearance of collateral vessels at the BRVO blockage site and was a clinical marker for intravascular reperfusion. Long-term epiretinal gliosis and subfoveal photoreceptor atrophy limited functional and visual recovery. [source]


    Time-course and characteristic morphology of retinal changes following combination of verteporfin therapy and intravitreal triamcinolone in neovascular age-related macular degeneration

    ACTA OPHTHALMOLOGICA, Issue 2 2010
    Shilla Lie
    Abstract. Purpose:, To identify characteristic morphological changes of the retina over time and the association with visual function after combined photodynamic therapy (PDT) and intravitreal triamcinolone (IVTA). Methods:, In this retrospective study, 40 patients (40 eyes) were treated with PDT and same-day IVTA. Optical coherence tomography (OCT), fluorescein angiography (FA) and evaluation of distance visual acuity (VA) were performed. The anatomical changes within intra- and subretinal compartments and their detailed analysis and grading were the main outcome measures. Results:, Intraretinal fluid (IRF) and subretinal fluid (SRF) by OCT decreased until 3 months (p < 0.01). At month 3, intraretinal cystoid spaces (ICS) had resolved or decreased in 84% of eyes, SRF in 58% and pigment epithelial detachment (PED) in 50%. Mean best-corrected VA (BCVA) improved significantly at month 1 (p < 0.01). Mean central retinal thickness (CRT) increased from 334 ,m at baseline to 439 ,m at day 1 (p = 0.03) before decreasing to 286 ,m at day 7 (p = 0.06), 233 ,m at month 1 (p = 0.001) and 255 ,m at month 3 (p = 0.001). Conclusion:, Combined verteporfin/IVTA therapy induces distinct time-related effects on the retina within the different intra- and subretinal compartments. [source]

    Is there still a place for vitrectomy in the treatment of macular edema due to venous occlusion ?

    ACTA OPHTHALMOLOGICA, Issue 2009
    CJ POURNARAS
    Purpose Persistent macular edema (ME) is the main cause of poor visual outcome in either non-ischemic BRVO or CRVO. Among multiples treatment approaches, vitreoretinal surgery with the goal to achieve the recanalisation of the occluded vessels and/or the resolution of ME, were proposed. Methods Vitrectomy with peeling of the posterior hyaloid and/or the internal limiting membrane,asociated to intravitreal (IVT) triamcinolone , neurotomy, sheathotomy, intravascular rtPA injection were studied in numerous nonrandomized cases series. Results Pars plana vitrectomy has been shown to reduce macular oedema and restore the normal foveal contour without significant change in best corrected visual acuity. In contrast, visual improvement occurs after vitrectomy for vitreous haemorrhage, epiretinal membrane formation and retinal detachment complicating BRVO. Evidence to date does not support any therapeutic benefit from radial optic neurotomy, optic nerve decompression, arteriovenous crossing sheathotomy or intravascular rtPA. Vitrectomy combined with IVT triamcinolone, induces a ME decrease rapidly and durably, without any improvement in visual acuity. Conclusion Vitrectomy with IVT triamcinolne seems to have a more durable effect than IVT triamcinolone alone.Vitrectomy, A-V sheathotomy combined with intravenous t-PA may offer benefits in BRVO. Despite uncertainty and open questions, surgical interventions are likely to be a therapeutic option for RVO in the future. Randomized and controlled studies are needed to confirm these results and to compare them to the natural course of the disease. [source]


    Rapid reduction of hard exudates in eyes with diabetic retinopathy after intravitreal triamcinolone: data from a randomized, placebo-controlled, clinical trial

    ACTA OPHTHALMOLOGICA, Issue 3 2009
    Jörgen Larsson
    Abstract. Purpose:, To assess the effect of triamcinolone acetonide over 3 months on hard exudates in patients with diabetic macular oedema (DMO). Methods:, Thirty-two eyes of 16 patients with DMO and hard exudates were included in a randomized, placebo-controlled trial. Treated eyes received a single-dose (4 mg) intravitreal injection of triamcinolone acetonide. Control eyes received an injection of subconjunctival saline. Results:, The overall area of hard exudates decreased significantly between the baseline and 3-month visits in treated eyes, but not in control eyes. The mean change in level of hard exudates between the two visits was , 0.75 arbitrary units (AU) (95% confidence interval [CI] , 1.32 to , 0.18) in the central plus inner circle (1500 ,m) and , 0.81 AU (95% CI , 1.49 to , 0.13) over the whole grid (3000 ,m) in treated eyes, compared with 0.31 AU (95% CI , 0.19 to 0.82) and 0.31 AU (95% CI , 0.11 to 0.74), respectively, in control eyes (p < 0.001). Mean visual acuity improved by five letters in treated but not in control eyes (p = 0.01). Conclusions:, Intravitreal triamcinolone reduces hard exudates in the short-term in eyes with DMO.

    Effects of repeated injection of intravitreal triamcinolone on macular oedema in central retinal vein occlusion

    ACTA OPHTHALMOLOGICA, Issue 3 2009
    Lili Wang
    Abstract. Purpose:, To investigate the effectiveness of repeated injections of intravitreal triamcinolone acetonide (IVTA) in the treatment of macular oedema caused by central retinal vein occlusion (CRVO). Methods:, Seventeen pseudophakic or aphakic eyes of 17 patients (10 male, seven female) with macular oedema caused by CRVO received a repeat injection of 4 mg IVTA, 16 weeks after the first injection of the same dose. The examination included measurements of best-corrected visual acuity (BCVA) for distance and central foveal thickness (CFT) by optical coherence tomography (OCT), preoperatively and 1, 2, 3 and 4 months postoperatively. The values were compared by paired- t test. Side-effects were monitored. Results:, BCVA and CFT were not significantly different before initial and repeat injections. Transient improvements of BCVA and CFT were achieved after both injections. At the end of follow-up, BCVA and CFT were significantly different compared to pre-injection values in the same group (P = 0.032, 0.049 in the initial-injection group and P = 0.001, 0.008 in the repeat-injection group, respectively). However, compared to the initial injection, BCVA measurements were significantly worse at each time-point (P = 0.043, 0.011, 0.010 and 0.012, respectively) after the repeat injection, as were CFT at 1, 2 and 3 months post-injection (P = 0.040, 0.015 and 0.025, respectively). The achieved maximum mean intraocular pressures were 20.00 [standard deviation (SD) 2.06] mmHg and 18.56 (SD 3.65) mmHg after the first and repeat injections, respectively. These values were not significantly different (P = 0.467). No other significant adverse events were noted during the study. Conclusion:, A repeat injection of 4 mg IVTA may not be as effective as an initial injection for the treatment of macular oedema caused by CRVO. [source]


    Photodynamic therapy with intravitreal application of triamcinolone acetonide in age-related macular degeneration: functional results in 54 patients

    ACTA OPHTHALMOLOGICA, Issue 2 2009
    Adjoa Frimpong-Boateng
    Abstract. Purpose:, This study aimed to investigate the functional results, efficacy and complications after photodynamic therapy (PDT) combined with intravitreal triamcinolone acetonide injection (IVTA) in patients with choroidal neovascularization (CNV) caused by age-related macular degeneration (AMD). Methods:, A retrospective analysis of clinical data for 54 patients with CNV resulting from AMD was carried out. All patients had a follow-up of 12 months. The patients were treated with standardized PDT and IVTA (4 mg) as a first-line treatment or following PDT failure. Visual acuity (VA), greatest linear diameter (GLD) of the CNV and foveal thickness were evaluated. Results:, Mean VA at baseline was 0.8 logMAR (0.4,1.4). After 12 months VA improved (> 2 lines) in 20.4% of patients and stabilized (± 2 lines) in 64.8%. There was no statistical significance in VA outcome between patients undergoing first-line treatment and patients with PDT failure; however, fewer PDT treatments were required to stop CNV activity in patients undergoing first-line treatment. At 12 months, a reduction in foveal thickness was seen in 67.7% of patients and a reduction in CNV GLD in 32.7%. Complications occurred in 22% of patients and included a transient rise in intraocular pressure, cataract and sterile hypopyon. Conclusions:, Our analysis shows that fewer PDT treatments were required to stop CNV activity when triamcinolone was used as first-line treatment. We can thus conclude that PDT combines synergistically with IVTA and the combination may lead to a cost reduction compared with PDT therapy alone. The overall complication rate of 22% is high and must be compared with complication rates caused by new intravitreal anti-VEGF (vascular endothelial growth factor) drugs in combination with PDT.

    Repeated peribulbar injections of triamcinolone acetonide: a successful and safe treatment for moderate to severe Graves' ophthalmopathy

    ACTA OPHTHALMOLOGICA, Issue 1 2009
    Marcela Bordaberry
    Abstract. Purpose:, In this study, we aimed to evaluate the efficacy of peribulbar triamcinolone injections to treat inflammatory signs of Graves' ophthalmopathy (GO) in patients with moderate to severe GO and associated optic neuropathy (ON). Methods:, Twenty-one patients with active GO [clinical activity score (CAS) , 4] and systemic thyroid disease under control were enrolled in this prospective pilot study. Peribulbar triamcinolone acetonide was injected in each orbit (42 eyes), in four doses of 20 mg at 2-week intervals. Ophthalmological examination including CAS evaluation, visual field, computerized tomography (CT) scan and digital photography were performed before and after treatment. Results:, Twenty-one patients (11 with moderate disease, 10 with ON) were enrolled in this study and followed for at least 14 months. Initial mean CAS was 6.38 ± 1.49, which dropped to 1.8 ± 1.12 after 6 months of treatment (P = 0.01; mean difference of 4.57 ± 1.56; range 1,8 score points). ON was diagnosed in 10 patients. Of these, 66% improved with peribulbar triamcinolone exclusively. A transitory increase in intraocular pressure in two patients was controlled with topic medication. Conclusion:, Peribulbar triamcinolone injections reduce the inflammatory signs of moderate GO, as measured by the CAS, and could also be used as an alternative treatment for ON. Randomized clinical trials are needed to compare the results of triamcinolone peribulbar injections to those of other treatment modalities. [source]


    Macular oedema in central retinal vein occlusion treated with intravitreal triamcinolone

    ACTA OPHTHALMOLOGICA, Issue 3 2006
    Christopher D. Gelston
    Abstract. Purpose:,To investigate the efficacy of intravitreal triamcinolone as treatment for macular oedema in central retinal vein occlusion (CRVO). Methods:,We conducted a retrospective comparative case series of nine patients with macular oedema associated with CRVO (six non-ischaemic and three ischaemic) treated with an intravitreal injection of 4 mg triamcinolone acetonide, compared with 10 control (observation) patients (six non-ischaemic and four ischaemic). Examination included visual acuity (VA) tests and complete ophthalmic examinations at baseline, 1, 2 and 6 months postoperatively. Results:,The mean baseline VA was 20/161 for CRVO treatment group patients and 20/75 for observation group patients (p = 0.15). No significant difference in VA between CRVO treatment group patients (20/99) and controls (20/282) was observed at the final 6-month visit (p = 0.33). Subgroup analysis of the non-ischaemic CRVO treatment patients compared with the non-ischaemic controls also showed no significant difference at the 6-month visit (20/59 and 20/100, respectively; p = 0.20). At 6 months, five of the six non-ischaemic treated patients had VA , 20/100, compared with five of the six non-ischaemic control patients. All patients tolerated the procedure well, but there was a significant increase in intraocular pressure by the 2-month visit (p = 0.015). Conclusions:,Intravitreal injection of triamcinolone may not be effective for treatment of macular oedema in all CRVO patients or all non-ischaemic CRVO patients. A trend towards VA improvement was noted but was not statistically significant. Although our treatment was not hindered by severe complications, there was a significant increase in IOP in the 2 months following treatment. [source]


    Suppression of lipopolysaccharide- and tumour necrosis factor-,-induced interleukin (IL)-8 expression by glucocorticoids involves changes in IL-8 promoter acetylation

    CLINICAL & EXPERIMENTAL IMMUNOLOGY, Issue 1 2007
    L. G. Tsaprouni
    Summary There is accumulating evidence that the transrepressional effect of glucocorticoids in down-regulating proinflammatory gene expression might be regulated by an action on histone acetylation. To investigate this, we studied the effect of two glucocorticoids (dexamethasone and triamcinolone acetonide) on reducing lipopolysaccharide (LPS)- and tumour necrosis factor (TNF)-,-induced interleukin (IL)-8 release in a monocytic cell line and two lymphocytic cell lines (HUT-78 and Jurkat). The effect of the histone deacetylase inhibitor trichostatin A (TSA) on LPS- and TNF-,-induced IL-8 release and its repression by glucocorticoids was also examined. LPS and TNF-, induced IL-8 release in all three cell lines and this induction was inhibited by both dexamethasone and triamcinolone. Pretreatment of cells with TSA enhanced basal and LPS- and TNF,-stimulated IL-8 release in all three cell lines. TSA also attenuated the inhibitory effect of glucocorticoids on stimulated IL-8 release. Chromatin immunoprecipitation assays confirmed that LPS and TNF-, enhanced histone acetylation at the IL-8 promoter and that this was inhibited by triamcinolone in all three cell types. Changes in histone acetylation at the IL-8 are important in its regulation by proinflammatory and anti-inflammatory agents, and modulation of this activity may have therapeutic potential in inflammatory conditions.

    Triamcinolone-induced cataract in eyes with diabetic macular oedema: 3-year prospective data from a randomized clinical trial

    CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 6 2010
    Mark C Gillies FRANZCO PhD
    Abstract Purpose:, To describe the 3-year risk of cataract after intravitreal triamcinolone (IVTA) injections for diabetic macular oedema and the outcomes of cataract surgery. Methods:, Prospective data from a randomized clinical trial were analysed. At baseline, 27 phakic eyes with diabetic macular oedema were randomized to receive IVTA and 25 to receive sham injection. After 2 years, initial sham-treated eyes were eligible to receive IVTA as the study became open label for the third year. The cumulative incidence of cataract surgery was the primary outcome of the study. Other outcomes assessed included progression of cataract, best-corrected logarithm of the minimal angle of resolution visual acuity before and after surgery and central macular thickness. Results:, Over the 3 years of the study, 15/27 (56%) phakic eyes in the IVTA treated group underwent cataract surgery as compared with 2/25 (8%) initial sham-treated eyes (P < 0.001). Mean visual acuity 6 months after cataract surgery was better than at entry into the trial. Two (15%) of the eyes in the IVTA-treated group undergoing cataract surgery had a loss of >15 letters. In the IVTA-treated group, 10/15 (67%) eyes that had three or more injections had progression of posterior subcapsular cataract by ,2 grades as compared with only 2/12 (17%) eyes that had fewer than three injections (P = 0.009). Conclusions:, Over half of the eyes receiving IVTA injections for diabetic macular oedema required cataract surgery within 3 years. In eyes with three or more IVTA injections, two-thirds had progression of posterior subcapsular cataract. Visual outcomes after cataract surgery were generally good, although a small proportion of eyes lost greater than 15 letters over the course of the study. [source]


    Factors associated with variability in response of diabetic macular oedema after intravitreal triamcinolone

    CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 6 2009
    MRCOphth, Shaheeda Mohamed MPH
    Abstract Purpose:, To identify factors associated with variability in anatomical and functional response of diabetic macular oedema (DMO) after 4 mg of intravitreal triamcinolone acetonide (ivTA), and for recurrence of macular oedema. Design:, Pooled analysis of individual data from two randomized controlled trials. Methods:, This was a multicentre study involving 107 eyes with DMO administered 4 mg ivTA. Predictive factors for response to treatment were evaluated with linear regression analysis. Factors associated with time to recurrence of oedema were studied with Cox proportional hazards modelling. Main outcome measures were maximum improvement in optical coherence tomography (OCT)-measured central foveal thickness (CFT) and best-corrected visual acuity (BCVA), final CFT and BCVA at 12 months and time to oedema recurrence. Results:, Greater reduction of retinal thickening occurred in eyes with worse baseline thickening (P < 0.001). There was also greater improvement of visual acuity in eyes with poorer preoperative BCVA levels (P < 0.001). Age, duration of oedema and previous macular laser treatment had no significant effect on maximal BCVA or CFT improvement. Eyes given 4 mg triamcinolone alone were more likely to develop recurrence of oedema at 12 months than those given a combination of 4 mg triamcinolone plus sequential laser (hazard ratio 2.60 [95% confidence interval: 1.45,4.67]). Conclusion:, Baseline OCT-measured retinal thickening and BCVA are important predictors of maximal anatomical and functional response of DMO to ivTA, respectively. Combination treatment strategy using sequential laser therapy may have a role in delaying recurrence of oedema after triamcinolone. [source]


    Late intraocular pressure rise following intravitreal triamcinolone injection

    CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 4 2007
    Christopher PR Williams FRCOphth
    Abstract Most ophthalmologists are aware of the risk of elevated intraocular pressure developing 1 or 2 months after an intravitreal injection of triamcinolone. However, the two cases reported here demonstrate that such a rise can occur significantly later than this. All patients who have had intravitreal steroid injection should therefore have prolonged intraocular pressure monitoring. [source]


    Severe loss of vision after removal of cataract caused by intravitreal triamcinolone in combination with photodynamic therapy for exudative age-related macular degeneration

    CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 5 2005
    Jörgen Larsson MD
    Abstract Intravitreal triamcinolone has been suggested as an adjunctive to photodynamic therapy in the treatment of exudative macular degeneration. One of the side-effects of intravitreal triamcinolone is the development of cataract, and it is known that cataract extraction can exacerbate macular degeneration. A case is presented where combined intravitreal triamcinolone and photodynamic therapy stopped the progression of the exudative macular degeneration. Subsequent progression of cataract required cataract extraction, which resulted in a very rapid progression of the exudative macular degeneration and loss of vision. [source]
