SUPRACHOROIDAL TRIAMCINOLONE ACETONIDE FOR REFRACTORY POSTOPERATIVE CYSTOID MACULAR EDEMA.

PURPOSE: To investigate outcomes of suprachoroidal triamcinolone acetonide (XIPERE, Bausch + Lomb) for the treatment of refractory postoperative cystoid macular edema. METHODS: Medical records of patients receiving suprachoroidal triamcinolone acetonide for postoperative cystoid macular edema were reviewed. Primary outcomes were visual acuity and central foveal thickness. RESULTS: A total of 32 eyes from 32 patients with a median (interquartile range) follow-up duration of 6 (2-7) months and 1 (1-2) suprachoroidal triamcinolone acetonide injection were included; 19 (59.4%) had a history of vitrectomy. The median (interquartile range) central foveal thickness decreased from 492 (379-629) µm to 267 (187-388) µm at 1 month (P < 0.001), 362 (218-521) µm at 3 months (P = 0.005), and 339 (206-514) µm at the final visit (P < 0.001). The median logarithm of the minimal angle of resolution visual acuity improved from 0.65 (0.48-0.97, 20/89) at baseline to 0.54 (0.35-0.88, 20/69) (P = 0.058) at 1 month, 0.54 (0.33-0.84, 20/69) at 3 months (P = 0.121), and 0.60 (0.33-0.88, 20/80) at the final visit (P = 0.021). Vitrectomized eyes had similar findings. Six eyes (18.8%) developed elevated intraocular pressure (>24 mmHg) (range: 25-49 mmHg) with a median intraocular pressure elevation of 13.5 mmHg compared with baseline, and all had prior glaucoma or ocular hypertension. CONCLUSION: Suprachoroidal triamcinolone acetonide reduced macular edema and improved vision in refractory postoperative cystoid macular edema, including vitrectomized eyes. Intraocular pressure should be monitored, especially in those with a history of glaucoma or ocular hypertension.

Effect of minoxidil combined with triamcinolone acetonide on alopecia areata by microneedle injection.

OBJECTIVE: Alopecia areata (AA) is often characterized by sudden onset of patchy hair loss. Topical corticosteroid injection is the most common treatment. This study retrospectively observed the clinical efficacy of microneedle minoxidil combined with triamcinolone acetonide in the treatment of AA. METHODS: A total of 230 patients with AA were selected. The experimental group (n = 120) received physician training and home microneedle treatment with minoxidil combined with triamcinolone acetonide once a week. Topical minoxidil and triamcinolone acetonide were used twice daily at other times. The control group (n = 110) was treated with minoxidil combined with triamcinolone acetonide, twice a day. Cure rate, response rate, SALT, dermatological Quality of Life Index (DLQI), visual analogue (VAS), and cost were assessed at weeks 4 and 12. RESULTS: Treated group SALT score(Severity of Alopecia Tool) remarkable lower than control group after treated 4 and 12 weeks. After 12 weeks treatment, DLQI score of the treated group (1.8 ± 1.67) were significantly lower than those of the control group (2.45 ± 1.88) (p < 0.05). VAS score and adverse reaction between two group showed no significant different (p = 0.823, p = 0.484 respectively). The total cost was 53.93 ± 15.85 in the treatment group and 53.26 ± 11.51 in the control group. There was no significant difference between the two groups (p = 0.72). In the treated group, the complete response rate (CR: 78.33%) and total effective rate (CR+PR: 95%) were significantly higher than those in the control group (CR: 40.91% and CR+PR: 51.82%), with statistically significant differences (p < 0.001). CONCLUSION: Microneedle introduction of minoxidil and triamcinolone acetonide in the treatment of AA is a safe, effective, economical, and convenient method, with few adverse reactions, and has a good application prospect.

Central Retinal Artery Occlusion after Peribulbar Injection of Triamcinolone Acetonide in Thyroid-associated Ophthalmopathy.

Central retinal artery occlusion (CRAO) is a form of acute ocular ischemic syndrome that causes visual loss. Timely treatment is of great importance for visual recovery, but the prognosis is usually poor. By analyzing the pathogenesis, diagnosis, and treatment process of a CRAO case after peribulbar injection of triamcinolone acetonide in thyroid-associated ophthalmopathy (TAO), this study aims to investigate the association of CRAO with hemodynamics and orbital pressure, thereby providing references in safety improvement of diagnosis and treatment on TAO.

Photobiomodulation versus corticosteroid in the management of erosive oral lichen planus: a randomized controlled clinical trial.

BACKGROUND: Oral lichen planus (OLP) is a chronic illness of immune origin that is typically treated with corticosteroids as a gold standard therapy. Photobiomodulation (PBM) may represent an alternative remedy that has the potential to treat a variety of pathological conditions by alleviating pain, reducing inflammation, and promoting tissue healing without the drawbacks of steroid therapies. Thus, the aim of the current study was to compare the effect of photobiomodulation to topical 0.1% triamcinolone acetonide on erosive oral lichen planus. METHODS: This randomized controlled clinical trial involved 44 patients complaining of erosive oral lichen planus. Patients were assigned to one of two groups: control group (n = 22) received 0.1% topical triamcinolone acetonide three times daily with miconazole oral gel once daily for 4 weeks, and photobiomodulation group (n = 22) received laser therapy by 980 nm diode laser utilizing output power 300 mW twice weekly for 5 weeks (a total of 10 sessions). The evaluation of patients was performed at baseline, 6 weeks, and 12 weeks postoperatively in terms of pain, clinical scores, and biochemical evaluation of salivary malondialdehyde levels. All recorded data were analyzed using Mann-Whitney test to compare the two studied groups regarding pain, lesion size, and salivary levels of malondialdehyde. Friedman test, followed by post hoc test, was used for comparison of the data within the same group along the 3 periods at baseline, 6 weeks, and 12 weeks. RESULTS: Both groups showed significant improvement in pain and clinical scores, with no statistical difference between them. Moreover, there was a significant improvement in salivary malondialdehyde levels for both groups, with no significant difference between them. CONCLUSIONS: Photobiomodulation could be a promising therapeutic modality for management of erosive oral lichen planus without the side effects of steroid therapy. The salivary malondialdehyde level could be used as a biomarker to evaluate the disease severity and its response to the treatment. TRIAL REGISTRATION: The study has been registered at ClinicalTrials.gov (NCT05951361) (19/07/2023).

Localized pemphigus vulgaris on scalp: an atypical presentation.

We present two middle-aged patients with pruritic, crusted scalp erosions. Skin biopsy showed epidermal acantholysis with IgG and C3 intercellular deposits on direct immunofluorescence, leading to the diagnosis of localized pemphigus vulgaris. Resolution of the lesions without relapse occurred after low doses of oral prednisone and intralesional triamcinolone acetonide.

Effect of triamcinolone acetonide on retinal inflammation and angiogenesis induced by pericyte depletion in mouse.

Triamcinolone acetonide (TA) has been shown to improve morphological and functional outcome in diabetic macular edema (DME) patients. However, the functional mechanism of TA has not been elucidated yet. In this study we investigated the detailed functional mechanism of TA using culture cells and retinopathy mouse models in which retinal inflammation and abnormal angiogenesis were induced by pericyte depletion. TA significantly prevented retinal hemorrhage, edema and partially improved abnormal angiogenesis. TA decreased retinal vascular endothelial growth factor (VEGF) concentration, presumably by preventing recruitment of macrophages into retina and TA also inhibited expression of inflammatory cytokines in retina. TA inhibited proliferation/migration of vascular endothelial cells and vessel sprouting. No direct inhibition of VEGF receptor 2 (VEGFR2) autophosphorylation was observed by TA. These results suggested that TA improved inflammatory retinal events which were induced in pericyte-deleted mice by mainly decreasing macrophage-derived VEGF and expression of inflammatory cytokines followed by attenuation of vascular permeability and proliferation/migration of endothelial cells. Furthermore, in these processes, translocation of glucocorticoid receptor (GR) was partially involved.

Triamcinolone acetonide suppressed scar formation in mice and human hypertrophic scar fibroblasts in a dose-dependent manner.

A hypertrophic scar is a complex medical problem. The study of triamcinolone acetonide for the treatment of scars is necessary. The 7mm full-thickness skin wounds were created on the back of BALA/c mice to construct the animal scar model. The different doses of triamcinolone acetonide injection or normal saline were injected into the wound on the 15th, 30th and 45th day after the operation. The skin histopathological changes of mice were observed by Hematoxylin-Eosin (H&E) staining. The proteins and mRNA expression level of scar-biomarkers (COL1, COL3, α-SMA) in mice scar tissue were detected by western blot and qRT-PCR. Besides, the effect of triamcinolone acetonide on the proliferation, invasion, and migration of human hypertrophic scar fibroblast (hHSFs) in vitro was also explored by cck-8, transwell and wound healing assays. After triamcinolone acetonide was injected into the wound, the proportion of scar was significantly reduced, and the treatment effect was concentration-dependently. H&E staining showed that the skin histopathological of mice was improved dose-dependently after injecting the low/middle/high-dosage of triamcinolone acetonide. The proteins and mRNA expression levels of COL1, COL3, and α-SMA were reduced dose-dependently in mice scar tissue. Furthermore, triamcinolone acetonide dose-dependently suppressed the proliferation, invasion, and migration of hHSFs in vitro. Together, triamcinolone acetonide suppressed scar formation in mice and human hypertrophic scar fibroblasts in a dose-dependent manner, phenotypically and mechanistically. The research and further exploration of triamcinolone acetonide in treating scar formation may find new effective treatment methods for the scar.

Intralesional Corticosteroid Administration in the Treatment of Keloids: A Scoping Review on Injection Methods.

BACKGROUND: Intralesional corticosteroid administration (ICA) is a first-line treatment for keloids. However, its clinical results are still highly variable and often suboptimal. Treatment results may strongly be influenced by various operator-dependent factors. The aim of this study was to map the details of ICA in keloids described in randomized controlled trials (RCTs), hence presenting the scientific practice of a first-line treatment for keloids in the best available evidence. SUMMARY: A systematic search was performed on PubMed, Ovid MEDLINE, Ovid EMBASE, and CENTRAL. Eligible studies were RCTs including patients with keloids treated with intralesional corticosteroids. Treatment and study design-related data were charted on a predefined form. Thirty-eight RCTs were included for data extraction. Triamcinolone acetonide was used in 37 (97.4%) studies. Dosing per cm2 could only be compared among ten (26%) studies and varied from 1 to 20 mg. The maximum dose per session varied from 20 to 80 mg. Local anesthetics were administered in seven (20%) RCTs. Treatment intervals varied from weekly to monthly, with 4 weeks most frequently (50%) used. Needle size was reported in eleven (29%) studies and varied from 26 to 30-gauge. Syringe size was specified in four (11%) studies, being 1 mL. The injection level was described in eleven (29%) studies. Blanching as endpoint was reported in ten (26%) studies. Outcome measures varied widely, from height, surface area, or volume, to Vancouver Scar Scale, Patient and Observer Scar Assessment Scale, pain and itch scores, patient satisfaction, and different efficacy rates. Only six studies had a follow-up of ≥6 months. Recurrence was identified in two studies with 18 weeks and 1 year of follow-up. Adverse events were reported in 23 (61%) studies.

Efficacy of injectable platelet-rich fibrin in the treatment of symptomatic oral lichen planus.

OBJECTIVES: The use of autologous platelet concentrates has shown growing evidence as a promising therapy. We conducted a split-mouth study to evaluate the effectiveness of injectable platelet-rich fibrin (PRF) compared with triamcinolone acetonide (TA) in the treatment of oral lichen planus (OLP). MATERIALS AND METHODS: This split-mouth randomized trial included 12 patients with symptomatic, bilateral OLP lesions. The participants were randomly allocated to receive a 1-ml intralesional PRF injection on one side of the buccal mucosa and a 0.5-ml TA injection on the counterpart side. The application was performed once a week for 4 weeks. The outcomes were measured using a visual analog scale score, REU score, and lesion areas. RESULTS: Both injectable TA and PRF were effective in the management of oral lichen planus. After 4 weeks of treatment, there was an average reduction in the VAS score (68.5% i-PRF, 91% TA) and an average reduction in the REU score (74% i-PRF, 91% TA). There were no statistically significant differences between the two treatment methods (p > 0.05). CONCLUSIONS: Intralesional injection with TA showed more effectiveness than i-PRF in the management of OPL lesions. Although, i-PRF cannot be considered a first-line treatment option, it showed promising alternative therapy choice with no side effects.

Management and follow-up of uveal effusion syndrome: a case report.

BACKGROUND: We present the management and follow-up of a case of uveal effusion syndrome (UES). CASE PRESENTATION: We study the relevant recent literature reports and review the aetiology, clinical classification, pathogenesis, diagnostic characteristics, treatment methods, and prognosis of this disease. When we encounter UES patients clinically, we can classify them according to their clinical characteristics and adopt different treatment plans for different types. The retina of this patient reattached 5 months after receiving eight periocular injections of triamcinolone acetonide (TA). CONCLUSIONS: For type III UES patients, local hormone therapy can be applied, and follow-up should be done to optimize the clinical outcome.

Intralesional steroid injections for inflammatory nail dystrophies in the pediatric population.

Intralesional injections of triamcinolone acetonide are widely used to successfully treat several inflammatory nail conditions. This procedure is well described in adults, but less frequently reported in children and teenagers, being largely considered too invasive and fear-provoking for pediatric patients. Our report shows how this procedure is feasible and successful in children, even without a digital block. The step-by-step technique and tips to reduce pain should encourage clinicians to offer it as an alternative option to children with inflammatory nail disorders.

Efficacy and Safety of Verapamil Versus Triamcinolone Acetonide in Treating Keloids and Hypertrophic Scars: A Systematic Review and Meta-Analysis.

BACKGROUND: Keloids and hypertrophic scars can affect the appearance and normal function of patients, and may severely affect patients' physical and mental health. Many methods have been used for the treatment of keloids and hypertrophic scars, there is no standardized method so far. The aim of this study was to compare the efficacy and safety of verapamil and triamcinolone acetonide (TAC) in treating keloids and hypertrophic scars. METHODS: All studies from their inception date up to August 2022 were searched using four databases (PubMed, Cochrane Library, MEDLINE, and EMBASE). The weighted mean differences and the risk ratio were calculated for comparing continuous variables and dichotomous variables, respectively. RESULTS: A total of nine randomized controlled trials involving 567 patients were identified. This meta-analysis indicated that TAC group showed significantly better effects compared with verapamil group in the reduction of height at 3 and 9 weeks, pliability at 3, 9, and 18 weeks, vascularity at 3, 6, 9, 12, 18, and 24 weeks, whereas verapamil group showed significantly better effects compared with TAC group in the reduction of pliability at 21 and 24 weeks. Verapamil group showed a significantly lower incidence of skin atrophy, telangiectasia, and hypopigmentation compared with TAC group. However, the incidence of burning sensation in verapamil group was higher than that in TAC group. CONCLUSION: Concerning the treatment of keloids and hypertrophic scars, TAC was more effective than verapamil for improving vascularity; TAC was superior to verapamil in improving height within 9 weeks of treatment; TAC produced superior result for improving pliability within 18 weeks of treatment, whereas verapamil produced superior result between 18 and 24 weeks of treatment. Verapamil had fewer adverse events than TAC and can be used as a safer alternative for the treatment of keloids and hypertrophic scars.

Endothelial loss following postoperative intracameral triamcinolone acetonide and subconjunctival dexamethasone injections.

OBJECTIVES: To compare endothelial toxicity and efficacy of two local steroid injections (intracameral triamcinolone acetonide and subconjunctival dexamethasone) in controlling postoperative inflammation following pars plana vitrectomy (PPV) combined with phacoemulsification cataract surgery. METHODS: This cohort included 54 patients that underwent combined surgery and received either intracameral triamcinolone acetonide injections (n = 27, IC-TA group) or subconjunctival dexamethasone (n = 27, Sc-Dex group) injections at the end of the surgery. All participants had at least 4 months or longer follow-up. A detailed ophthalmologic examination including intraocular pressure (IOP) measurement and specular microscopy was performed at every visit. RESULTS: Endothelial cell density (ECD) reduced significantly in IC-TA group postoperatively (2418 vs. 2249, p = 0.019), while it did not change significantly in Sc-Dex group (2541 vs. 2492, p = 0.247). Postoperative ECD was also significantly lower in IC-TA group compared to Sc-Dex group (p = 0.011). Preoperative and postoperative IOP values remained unchanged both in IC-TA and Sc-Dex groups (p = 0.424 and p = 0.523, respectively). However, 4 patients in IC-TA group and 5 patients in the Sc-Dex group needed glaucoma medications. The postoperative need for glaucoma medications was similar between the groups (p = 0.347). Postoperative inflammation was well controlled in both groups and none of the patients developed fibrin membrane or synechiae postoperatively. CONCLUSION: Both treatments were effective in controlling postoperative inflammation, but patients in IC-TA group experienced significantly higher endothelial loss. Sc-Dex injections are safer in terms of endothelial loss and preferable to control postoperative inflammation following complex intraocular surgeries.

Comparison of topical purslane & topical 0.1% triamcinolone acetonide in the management of oral lichen planus - a double blinded clinical trial.

AIM AND BACKGROUND: Oral lichen planus (OLP) is a chronic autoimmune mucocutaneous disorder of unknown etiology and treatment is targeted at alleviating symptoms. At present, corticosteroids are the mainstay treatment, and their side effects hamper their long-term use, demanding alternative therapy. This study intended to assess the efficacy of topical purslane (Portulaca oleracea) at two concentrations, 5% and 10%, in OLP and to compare the level of clinical improvement in comparison to topical 0.1% triamcinolone acetonide gel. MATERIALS AND METHODS: After sample size determination, thirty-four subjects confirmed histopathologically with OLP were included in the study. They were divided into 3 groups, Group 1(Control) was treated with 0.1% triamcinolone acetonide, and Group 2(Case) and 3 (Case) were treated with topical purslane 5% and 10%, respectively. They were examined at baseline, 14 days, 30 days, 60 days, and 90 days. Clinical improvement was then analyzed at the end of 90 days using a visual analog scale (VAS) and Thongprasom's criteria. RESULTS: The study was analyzed statistically and a P value of < 0.05 was considered statistically significant. Intragroup comparison revealed a statistically significant difference between the five time periods (baseline, 14 days, 30 days, 60 days, and 90 days) for the study variables (burning sensation, pain, lesion score, clinical response, symptomatic response) for all three groups (p = 0.001). Alleviation of all symptoms and remission of the lesion were noted for all three groups at the end of three months. CONCLUSION: Purslane is a magical herb with a plethora of rich nutrients, ease in accessibility and devoid of side effects. It was concluded that its preparation is beneficial and can be a safer alternative long-term drug for the management of OLP. CLINICAL SIGNIFICANCE: With available literature evidence, our present study is the first of its kind to formulate a topical gel with purslane to treat symptomatic OLP. Our study had a longer follow-up of 3 months compared to other studies in the literature.

The effect of sage (Salvizan gel) compared to triamcinolone acetonide on the treatment of recurrent aphthous stomatitis: a double-blinded randomized clinical trial.

BACKGROUND: Recurrent Aphthous Stomatitis (RAS) is one of the most common lesions of the oral mucosa. Herbal medicine can be used for the treatment of this disease. The present study aimed to compare the effects of topical application of Sage (Salvizan) and triamcinolone acetonide gels on RAS. METHODS: This double-blind clinical study recruited sixty patients with minor aphthous ulcers. Half of the patients were treated with Salvizan gel, and the other half were treated with oral triamcinolone acetonide gel. The effect of Salvizan topical gel was evaluated and compared with that of oral triamcinolone acetonide gel. Factors such as Pain recovery time, wound healing time, and pain level was evaluated. Data were analyzed by SPSS version 22 using independent t-test, paired t-test, repeated measures ANOVA, and survival analysis, including Kaplan-Meier and Cox regression. RESULTS: The mean duration of pain recovery was 1.5 days for Salvizan and 2.5 days for triamcinolone acetonide (p < 0.001). Moreover, the duration of wound healing was 3.3 days for Salvizan and 6 days for triamcinolone acetonide (p < 0.001). Patients' satisfaction from factors such as taste and smell had no significant difference between the two groups. CONCLUSION: The results of this study showed that Salvizan gel is very effective in the treatment of RAS. It was significantly better than triamcinolone acetonide in the pain recovery and wound healing. These promising results favor herbal treatments and show that they can be used more commonly for treating diseases such as RAS. TRIAL REGISTRATION: This study was approved by the ethics committee of Isfahan University of Medical Sciences (IR.MUI. RESEARCH: REC.1399.834) on 17/03/2021. It was also registered in the Iranian Registry of Clinical Trials (IRCT20100202003251N7).

Clinical and biochemical assessment of the effect of topical use of coenzyme Q10 versus topical corticosteroid in management of symptomatic oral lichen planus: randomized controlled clinical trial.

BACKGROUND: Oral lichen planus (OLP) is a chronic mucocutaneous immunologically mediated condition that has a great adverse effect on oral functions. Corticosteroids are still the first drugs of choice used in the treatment of OLP; however, they have extensive medical side effects. The present study was carried out to assess the clinical therapeutic effect of the topical use of coenzyme Q10 (coQ10 or ubiquinol) versus topical corticosteroids in the management of symptomatic OLP and to determine whether the effect, if any, was due to the powerful antioxidant activity of coQ10. SUBJECTS AND METHODS: We performed a randomized, double blinded controlled trial at the Faculty of Dentistry, Cairo University, Egypt. The study was conducted on 34 patients suffering from symptomatic OLP. Patients were randomly divided into two groups: intervention group (I),who received topical CoQ10 in the form of mucoadhesive tablets (40% CoQ10) 3 times daily for one month and control group (II),who received topical corticosteroid (kenacort in Orabase: triamcinolone acetonide 0.1% 5-g adhesive paste - dermapharm), 4 times daily for one month. Patients were evaluated at one-week intervals using the clinical parameters (score) of pain (VAS) and lesion size. Additionally, salivary levels of malondialdehyde (MDA) were detected in both groups before and after treatment using ELISA. All recorded data were analysed using independent t test, ANOVA followed by Bonferroni post hoc test for lesion size and salivary level of MDA data and Mann-Whitney U test and Friedman test for VAS data. RESULTS: Both groups showed a significant reduction in pain and the size of the lesions (p ≤ 0.05) with no statistically significant difference between them (p > 0.05), and this clinical improvement was associated with a reduction in the salivary levels of MDA in both groups. CONCLUSIONS: The topical use of CoQ10 mucoadhesive tablets was as effective as the topical use of triamcinolone acetonide, and its clinical effect was associated with a reduction in the salivary level of MDA. TRIAL REGISTRATION: The study protocol was registered at www. CLINICALTRIAL: gov (NCT04091698) and registration date: 17/9/2019.

Comparing intralesional triamcinolone and verapamil-triamcinolone injections in keloids: A single-blinded randomised clinical trial.

INTRODUCTION: In this clinical trial, we investigated the efficacy of two treatment methods for keloids resulting from surgical incisions: intralesional triamcinolone injections alone versus in combination with verapamil. MATERIAL AND METHODS: Patients were divided into two groups: one received triamcinolone alone (Group T) and the other received a triamcinolone-verapamil blend (Group VT). Regular treatments were conducted until the keloids were nearly flat or for a maximum of eight sessions. RESULTS: Both groups showed significant improvements, but Group VT saw quicker resolution of skin redness and needed fewer sessions. Though the Vancouver Scar Scale (VSS) scores were generally similar across both groups, Group VT exhibited greater improvements, leading to lower final scores. The VT group also attained normal scar flexibility faster than the T group. CONCLUSION: These findings suggest that the combination of verapamil and triamcinolone provides a more effective treatment for keloids, thereby highlighting the potential of verapamil in scar reduction.

Combined Treatment of Persistent Diabetic Macular Edema with Aflibercept and Triamcinolone Acetonide in Pseudophakic Eyes.

Background and Objectives: The main cause of the vision loss in diabetics is the development of diabetic macular edema, regardless of the stage of diabetic retinopathy. The paper aimed to examine whether the additional intravitreal application of triamcinolone acetonide to continuous anti-vascular endothelial growth factor therapy could improve therapeutic outcomes for pseudophakic eyes with persistent diabetic macular edema. Materials and Methods: twenty-four pseudophakic eyes with refractory diabetic macular edema, that had appeared despite three previously administered intravitreal injections of aflibercept, were divided into two groups (twelve eyes in each group). The first group continued to have aflibercept administered according to a fixed dosing regimen (once in two months). Triamcinolone acetonide 10 mg/0.1 mL (administered once per four months) was included for the second group, i.e., their treatment continued with a combination of aflibercept + triamcinolone acetonide. Results: The reduction in central macular thickness was higher in the eyes treated with combined therapy (aflibercept + triamcinolone acetonide) compared with the use of aflibercept alone during the entire 12-month follow-up period (3rd month p = 0.019; 6th month p = 0.023; 9th month p = 0.027; 12th month p = 0.031). As was evident from the p-values, the differences were statistically significant. No statistically significant difference was recorded for visual acuity: 3rd month p = 0.423; 6th month p = 0.392; 9th month p = 0.413; 12th month p = 0.418. Conclusions: Combined anti-vascular endothelial growth factor and steroid therapy leads to a better anatomical outcome of persistent diabetic macular edema in pseudophakic eyes, but does not lead to a more significant improvement in visual acuity than continuous anti-VEGF therapy alone.

Faricimab for Diabetic Macular Edema in Patients Refractory to Ranibizumab or Aflibercept.

Background and Objectives: Faricimab is the first intravitreal injection of vascular endothelial growth factor-A and angiopoietin-2 bispecific monoclonal antibody. Here, we evaluate the functional and anatomical outcomes of faricimab treatment in patients with diabetic macular edema (DME) that was refractory to ranibizumab or aflibercept. Materials and Methods: We performed a retrospective, observational, consecutive-case study of patients who had DME that was refractory to treatment with ranibizumab or aflibercept and were treated with faricimab between July 2022 and January 2023 under a pro re nata regimen. All the participants were followed for ≥4 months after the initiation of faricimab. The primary outcome was a recurrence interval of ≥12 weeks, and the secondary outcomes were the changes in best-corrected visual acuity (BCVA) and central macular thickness (CMT). Results: We analyzed 18 eyes of 18 patients. The mean recurrence interval of previous anti-VEGF injection was 5.8 ± 2.5 weeks, which was significantly extended to 10.8 ± 4.9 weeks (p = 0.0005) by the switch to faricimab. Eight patients (44.4%) achieved a recurrence interval of ≥12 weeks. A history of subtenon injection of triamcinolone acetonide (p = 0.0034) and the presence of disorganization of the retinal inner layers (p = 0.0326) were found to be significantly associated with a recurrence interval of <12 weeks. The mean BCVAs were 0.23 ± 0.28 logMAR and 0.19 ± 0.23 logMAR, and the mean CMTs were 473.8 ± 222.0 µm and 381.3 ± 219.4 µm at baseline and 4 months, respectively, but these changes were not statistically significant. None of the patients experienced serious adverse events. Conclusions: Faricimab may extend the treatment interval for patients with DME that is refractory to ranibizumab or aflibercept. DME previously treated with the subtenon injection of triamcinolone acetonide or associated with disorganization of the retinal inner layers may be less likely to be associated with a longer recurrence interval after switching to faricimab.

[Cost-effectiveness analysis of Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray in treatment of chronic rhinosinusitis].

This study aims to evaluate the effectiveness and economic efficiency of Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray in the treatment of chronic rhinosinusitis(CRS). The randomized controlled trial(RCT) of Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray in the treatment of CRS was searched against EMbase, PubMed, Cochrane Library, CNKI, VIP, SinoMed, and Wanfang. The efficacy, nasal mucociliary transport time, and safety of the therapy above in the treatment of CRS were analyzed with single-group rate and Meta-analysis, and the economy and sensitivity were evaluated from the perspective of payer. A total of 9 RCTs were included, including 1 145 patients. Meta-analysis showed that compared with Triamcinolone Acetonide Nasal Spray alone, Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray in the treatment of CRS patients increased the effective rate(RR=1.17, 95%CI[1.11, 1.24], P<0.000 01) and shortened the nasal mucociliary transport time(MD=-3.32, 95%CI[-5.86,-0.78], P=0.01), there was no significant difference in the incidence of adverse reactions between the two groups. The incremental cost-effectiveness analysis showed that the treatment costs of the control group and the observation group were 44.15 yuan and 1 044.96 yuan, respectively. In the Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray treatment group, 75.48 yuan was spent to improve the effective rate of CRS by 1%. The one-way sensitivity analysis indicated the days of treatment, the RR of Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray, the price of unit preparation of Biyuan Tongqiao Granules, and the effective rate of Triamcinolone Acetonide Nasal Spray alone had great influence on the incremental cost-effectiveness ratio. In conclusion, Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray improves the therapeutic effect on CRS. The probabilistic sensitivity analysis showed that when the willingness to pay was greater than 7 920 yuan(less than 0.1 of GDP per capita 8 098 yuan), the combined therapy was economically superior to the control. Due to the limited number of articles published, it is necessary to carry out a real-world clinical trial of Biyuan Tongqiao Gra-nules and Triamcinolone Acetonide Nasal Spray in the treatment of CRS, so as to compare the cost-effectiveness of Biyuan Tongqiao Granules and Triamcinolone Acetonide Nasal Spray.
