RÉSUMÉ

Pityriasis rubra pilaris (PRP) is a rare dermatological condition which may present with ocular manifestations. We report a case of recurrent cicatricial ectropion (CE) with topical beta-blocker use in the rare dermatological condition PRP. The patient underwent release of scar tissue, lateral tarsal strip and full-thickness supraclavicular skin graft for CE following immunosuppression with methotrexate for 3 months. Postoperatively, CE recurred, with skin graft shrinkage and resumption of periocular disease activity, 8 weeks following the introduction of topical timolol. The patient was referred for further immunosuppression and substitution of timolol before consideration for further surgery. PRP has a variety of potential ocular complications. Surgery has a high risk of recurrence and should be performed when the overall disease is quiescent and drugs, which could trigger reactivation, have been discontinued and/or substituted. Skin grafts should be oversized to off-set shrinkage.

RÉSUMÉ

The management protocol for patients with neovascular age-related macular degeneration (nAMD) involves multiple intravitreal injections (IVI) of anti-VEGF drugs. The ability to reduce the peak intraocular pressure (IOP) rise is greatly important in clinical practice. PURPOSE: This study evaluates the effect of topical hypotensive drugs on the short-term IOP rise after IVI of anti-VEGF drugs in patients with nAMD. MATERIAL AND METHODS: The prospective study included 80 patients with newly diagnosed nAMD. Before the start of treatment, the patients were divided into 4 groups of 20 people each: 1st - controls, who received no prophylactic drugs, in the 2nd, 3rd and 4th groups local instillations of one drop of hypotensive drugs brinzolamide 1%, brinzolamide-timolol, brimonidine-timolol were performed in the conjunctival sac twice: 1 day before the injection (at 20:00) and on the day of the injection 2 hours before the manipulation (at 08:00), respectively. IOP was measured in each patient using ICare Pro non-contact tonometer before injection, as well as 1 min, 30 and 60 min after injection. RESULTS: Prophylactic use of hypotensive drugs was associated with a significant decrease in IOP immediately after IVI compared to the same parameter in the 1st group (p<0.001), the maximum decrease in IOP values was observed when using a fixed combination of brimonidine-timolol by 12.1 mm Hg compared to the controls (p<0.001), the combination of brinzolamide-timolol reduced IOP by 8.5 mm Hg (p<0.001), brinzolamide 1% led to the smallest decrease in IOP - by 5.1 mm Hg (p<0.001). CONCLUSION: Study patients that received instillations of brimonidine-timolol combination of one drop into the conjunctival sac 1 day before the injection and on the day of the injection showed the maximum decrease in IOP compared to patients of the other groups.

RÉSUMÉ

Purpose: To compare the efficacy of Brinzolamide-Brimonidine (BB) (1%+0.2%) with the gold standard Latanoprost-Timolol (LT) (0.005%+0.5%) in treating primary open-angle glaucoma (POAG) and ocular hypertension (OHT). Methods: A 1-year prospective study, spanning from May 2022 to May 2023, conducted at a tertiary eye-care hospital. Participants, aged 40-60, with a baseline intraocular pressure (IOP) >21 mm Hg, requiring a >30% reduction, were enrolled. Group A (n = 100) received BB, and Group B (n = 100) received LT. Outcomes were assessed at 1 month (IOP difference from baseline), 3 and 6 months (mean diurnal variations). Results: The mean age at presentation was 55.5 ± 4.5 years in Group A and 54.7 ± 4.2 years in Group B. At 1 month, Group A exhibited a mean IOP of 18.7 mm Hg, while Group B had 17.6 mm Hg, with no statistically significant difference (P = 0.53). No significant diurnal variation was observed in either group (P = 0.07). Target pressure was achieved in 88% of patients in Group A and slightly higher at 92% in Group B. Moreover, no serious side effects were reported, and compliance was higher in Group B (98%) compared to Group A (96%). Conclusion: Although LT showed slightly better and sustained IOP reduction, the difference was not statistically significant. Both BB and LT demonstrated comparable outcomes for managing POAG and OHT.

RÉSUMÉ

PURPOSE: To assess efficacy, safety, and tolerability of the preservative-free (PF) fixed-dose combination (FC) of tafluprost 0.0015%/timolol 0.5% (PF tafluprost/timolol FC) in treatments-naive patients with primary open-angle glaucoma (POAG). METHODS: This was a retrospective, real-world clinical practice setting study that included 107 eyes of 107 subjects with POAG who had never been treated for glaucoma. All subjects were received PF tafluprost/timolol FC once daily. Intraocular pressure (IOP) levels were documented for each eye at the untreated baseline and up to 6 months after the initiation of medical treatment. All adverse events, including ocular and systemic adverse reactions, were recorded. Additionally, the reasons for medication discontinuations were thoroughly documented. RESULTS: A total of 32 POAG patients with high-baseline IOP (>21 mmHg) and 75 with normal-baseline IOP were included in the study. The subjects' baseline mean age was 62.4 ± 8.7 years (range, 26.0-85.0 years); among them, 42 were female (39.3%). Mean IOP at baseline for all patients was 18.6 ± 4.3 mmHg. The mean IOP at 6 months was 12.6 ± 4.7 mmHg, representing a significant decrease compared to the baseline (-32%, p < 0.001). In POAG patients with high-baseline IOP, mean IOP was significantly lowered from 28.0 ± 5.7 mmHg at baseline to 18.0 ± 5.5 mmHg (-35%, p < 0.001); in patients with normal-baseline IOP, from 14.6 ± 3.4 mmHg at baseline to 10.3 ± 4.1 mmHg (-29%, p < 0.001). PF tafluprost/timolol FC was well-tolerated and safe. After 6 months, 97.2% of all patients remained on therapy. CONCLUSIONS: In this real-world observational study, once-daily treatment with PF tafluprost/timolol FC demonstrated clinically relevant and statistically significant efficacy, as well as safety and good tolerability, in treatment-naive patients diagnosed with POAG.

RÉSUMÉ

El diagnóstico diferencial clínico entre los hemangiomas congénitos (HC) y los infantiles (HI) es complicado pero esencial para el tratamiento. El marcador inmunohistoquímico GLUT-1 ayuda a distinguirlos, sin embargo, la biopsia no es habitual. Se diseñó un estudio retrospectivo incluyendo los HI y a los HC diagnosticados en un hospital terciario en un periodo de 3 años, con el objetivo de describir y comparar los principales aspectos clínicos, epidemiológicos y terapéuticos. Se incluyeron un total de 107 hemangiomas, 34 HC (NICH/PICH/RICH), 70 HI y 3 pendientes de clasificar. El HI superficial de cabeza y cuello fue el tumor más frecuente. El tronco fue la localización más frecuente de los HC. Los factores de riesgo estudiados fueron más frecuentes en el grupo de los HI. Para los HI, el tipo de respuesta obtenida fue independiente de las variables (sexo, fecundación in vitro, profundidad, localización y tipo de tratamiento) (AU)

RÉSUMÉ

Most common intraocular pressure (IOP) reduction regimens for the management of glaucoma include the topical use of eye drops, a dosage form that is associated with short residence time at the site of action, increased dosing frequency, and reduced patient compliance. In situ gelling nanofiber films comprising poly(vinyl alcohol) and Poloxamer 407 were fabricated via electrospinning for the ocular delivery of timolol maleate (TM), aiming to sustain the IOP-lowering effect of the ß-blocker, compared to conventional eye drops. The electrospinning process was optimized, and the physicochemical properties of the developed formulations were thoroughly investigated. The fiber diameters of the drug-loaded films ranged between 123 and 145 nm and the drug content between 5.85 and 7.83% w/w. Total in vitro drug release from the ocular films was attained within 15 min following first-order kinetics, showing higher apparent permeability (Papp) values across porcine corneas compared to the drug's solution. The fabricated films did not induce any ocular irritation as evidenced by both the hen's egg test on chorioallantoic membrane and the in vivo Draize test. In vivo administration of the ocular films in rabbits induced a faster onset of action and a sustained IOP-lowering effect up to 24 h compared to TM solution, suggesting that the proposed ocular films are promising systems for the sustained topical delivery of TM.

RÉSUMÉ

Our study aims to determine whether the beta-adrenergic system is involved in the regulation of lymphatic drainage from the eye. For this purpose, we assessed the effect of 2 topical beta-adrenergic blockers, timolol and betaxolol, commonly used as glaucoma drugs, on lymphatic clearance of albumin from the aqueous humor to neck lymph nodes. Adult mice were treated with either topical timolol, a non-selective ß-blocker, 0.5% (n = 8), or topical betaxolol, a selective ß1-adrenergic blocker, 0.5% (n = 6) twice daily for 14 days and compared to respective control groups (n = 5 and n = 7). Changes in lymphatic clearance from the eye were assessed using a quantitative in vivo photoacoustic imaging approach. In all subjects, right eye and neck lymph nodes were longitudinally assessed by sequential photoacoustic imaging just prior to near-infrared dye injection into the anterior chamber of the eye, and 20 min, 2 and 4 h after injection. Repeat measurements of mean pixel intensities (MPIs) of right eyes and nodes were performed at all timepoints. The areas under the curves (AUC) were calculated and the AUC of the treated-group was compared to that of controls using the Mann-Whitney U test. The slopes of MPI of each region of interest over time were compared using the linear mixed model after adjusting for IOP decrease after treatment and other parameters such as sex and body weight. In the timolol-treated group, right neck nodes showed significant decrease in AUC signal intensity compared with controls (P = 0.003), and significant decrease in slope of MPI compared with controls (P = 0.0025). In the betaxolol-treated group, right neck nodes showed significant decrease in AUC signal intensity compared with controls (P = 0.02), and significant decrease in slope of MPI compared with controls (P = 0.0069). Topical treatment with timolol and betaxolol reduced lymphatic clearance of albumin from the aqueous humor to the neck lymph nodes. This finding may be relevant for the management of secondary glaucomas and inflammatory eye disease in which the clearance of accumulated proteins and antigen from the eye is important to disease recovery and sight protection. This study suggests that the beta-adrenergic system plays a role in the regulation of lymphatic clearance from the eye.

RÉSUMÉ

Glaucoma is an ophthalmic disease that is characterized by elevated intraocular pressure (IOP). Eye drops are the preferred choice to reduce IOP for the treatment of glaucoma. However, the bioavailability of eye drops is low (<5%). Their long-term frequent administration cannot ensure patient compliance, which is the main reason for treatment failure. Inspired by lollipop, herein, a multilayered sodium alginate-chitosan (SA-CS) hydrogel ball (HB) decorated by zinc oxide-modified biochar (ZnO-BC) is developed as a new drug delivery system. The multilayer structure encapsulate timolol maleate (TM) and levofloxacin inside the different layers to realize the sustained release of drugs, which can control ocular hypertension and prevent infection effectively. The results show that the release of TM can be sustained in vitro for longer than 2 weeks. Moreover, IOP is also effectively reduced in vivo. Meanwhile, the photothermal conversion activity of ZnO-BC can regulate drug release on demand after stimulation by near-infrared irradiation. More importantly, the designed HB also shows good biocompatibility and antibacterial properties in vitro and in vivo. In summary, ZnO-BC-SA-CS HB can effectively reduce IOP and is expected to replace the classical tedious eye drop strategy, having potential utilization value in the treatment of glaucoma.

RÉSUMÉ

BACKGROUND: Infantile hemangiomas (IH) are the most common vascular, benign tumors of childhood with a prevalence of 4-5%. Due to intense vasculogenesis, they proliferate during infancy, then involute at an unpredictable rate, extent of involution, and quality of residual tissue. Depending on the location, they may be associated with anomalies of other organ systems (PHACE, PELVIS syndroms). In recent decades, knowledge about hemangiomas has improved, and therefore therapeutic possibilities have improved. Today, the non-selective beta blocker-propranolol is considered the drug of first choice in the treatment of infantile hemangiomas. It is desirable to start treatment in the proliferative phase of hemangioma growth for the best possible effect. The dynamics of drug administration, time interval of dose increase and monitoring of patients during treatment vary from one Institution to another and are still the subject of discussion. OBJECTIVE: We presented the case of a child with infantile hemangioma of the lumbo-sacral region, treated with combination therapy with systemic propranolol and topical timolol, with satisfactory effect in the end. CONCLUSION: Propranolol is considered a drug with well-studied side effects and a safety profile. During 6 months of treatment, it leads to complete or almost complete withdrawal of the hemangioma. Treatment should be started in the hemangioma proliferation phase for the best possible therapeutic effect.

RÉSUMÉ

Quantitative understanding of pharmacokinetics of topically applied ocular drugs requires more research to further understanding and to eventually allow predictive in silico models to be developed. To this end, a topical cocktail of betaxolol, timolol and atenolol was instilled on albino rabbit eyes. Tear fluid, corneal epithelium, corneal stroma with endothelium, bulbar conjunctiva, anterior sclera, iris-ciliary body, lens and vitreous samples were collected and analysed using LC-MS/MS. Iris-ciliary body was also analysed after intracameral cocktail injection. Non-compartmental analysis was utilized to estimate the pharmacokinetics parameters. The most lipophilic drug, betaxolol, presented the highest exposure in all tissues except for tear fluid after topical administration, followed by timolol and atenolol. For all drugs, iris-ciliary body concentrations were higher than that of the aqueous humor. After topical instillation the most hydrophilic drug, atenolol, had 3.7 times higher AUCiris-ciliary body than AUCaqueous humor, whereas the difference was 1.4 and 1.6 times for timolol and betaxolol, respectively. This suggests that the non-corneal route (conjunctival-scleral) was dominating the absorption of atenolol, while the corneal route was more important for timolol and betaxolol. The presented data increase understanding of ocular pharmacokinetics of a cocktail of drugs and provide data that can be used for quantitative modeling and simulation.

RÉSUMÉ

Importance: Treatment of infantile hemangioma (IH) with topical timolol in the first 2 months of life (early proliferative phase) may prevent further growth and the need for treatment with oral propranolol. To our knowledge, no studies have determined whether beginning early treatment with timolol for IH is better than in other proliferative stages. Objective: To evaluate the efficacy and safety of timolol maleate solution, 0.5%, for the early treatment of IH in infants younger than 60 days. Design, Setting, and Participants: This multicenter, randomized, double-blind, placebo-controlled, phase 2a pilot clinical trial included patients aged 10 to 60 days with focal or segmental hemangiomas (superficial, deep, mixed, or minimal/arrested growth). Patients were randomly assigned to treatment with topical timolol maleate solution, 0.5%, or placebo twice daily for 24 weeks. Changes in lesion size (volume, thickness) and color were evaluated from photographs taken at 2, 4, 8, 12, 24, and 36 weeks. Vital signs and adverse effects were recorded at each visit. The study was carried out from November 2015 to January 2017, and data analyses were completed in September 2019. Main Outcomes and Measures: The primary outcome of complete or nearly complete IH resolution and the secondary outcomes of changes in lesion thickness, volume, and color were evaluated by a blinded investigator. Results: Of the 69 patients recruited, the mean (SD) age was 48.4 (10.6) days; 55 (80%) were female; and 51 (74%), 11 (16%), 6 (9%), and 1 (1%) had superficial, mixed, abortive, or deep IHs, respectively. The IHs were localized, segmental, or indeterminate in 60 (87%), 7 (10%), and 2 (3%) patients, respectively. The IHs were located on the head and/or neck (n = 23 [33%]) or other body sites (n = 46 [67%]). The study was completed by 26 of 33 (79%) patients receiving timolol and 31 of 36 (86%) receiving placebo. There were no significant differences between timolol and placebo for complete or nearly complete IH resolution at 24 weeks (n = 11 [42%] vs n = 11 [36%]; P = .37). The odds ratio of complete or almost complete response vs no response at week 24 was 1.33 (95% CI, 0.45-3.89). There were no between-group differences in IH size (volume, thickness). An improvement in color was observed at week 4 in the timolol group, and timolol was well tolerated with no systemic adverse effects. Conclusions and Relevance: In this randomized clinical trial, results demonstrated that topical timolol is well tolerated for the treatment of early proliferative IH but provides limited benefit in lesion resolution when given during the early proliferative stage.

RÉSUMÉ

Beta-adrenergic blocking agents (abbreviated as beta-blockers) have been used for treating various cardiovascular diseases. However, the potential for asthma exacerbation is one of the major adverse effects of beta-blockers. This study aimed to compare the level of risk for an asthma attack in patients receiving various beta-blockers. We searched for randomized controlled trials (RCTs) of either placebo-controlled or active-controlled design. The current network meta-analysis (NMA) was conducted under a frequentist model. The primary outcome was the incidence of asthmatic attack. A total of 24 RCTs were included. Overall NMA revealed that only oral timolol [risk ratio (RR) = 3.35 (95% confidence interval (CI) 1.04-10.85)] and infusion of propranolol [RR = 10.19 (95% CI 1.29-80.41)] were associated with significantly higher incidences of asthma attack than the placebo, whereas oral celiprolol [RR = 0.39 (95% CI 0.04-4.11)], oral celiprolol and propranolol [RR = 0.46 (95% CI 0.02-11.65)], oral bisoprolol [RR = 0.46 (95% CI 0.02-11.65)], oral atenolol [RR = 0.51 (95% CI 0.20-1.28)], infusion of practolol [RR = 0.80 (95% CI 0.03-25.14)], and infusion of sotalol [RR = 0.91 (95% CI 0.08-10.65)] were associated with relatively lower incidences of asthma attack than the placebo. In participants with a baseline asthma history, in addition to oral timolol and infusion of propranolol, oral labetalol, oxprenolol, propranolol, and metoprolol exhibited significantly higher incidences of asthma attack than did the placebo. In conclusion, oral timolol and infusion of propranolol were associated with a significantly higher risk of developing an asthma attack in patients, especially in those with a baseline asthma history, and should be avoided in patients who present a risk of asthma.Trial registration: PROSPERO CRD42020190540.
