Findings from Research

In a study of 12 patients receiving subretinal voretigene neparvovec (VN) gene therapy for retinal disease, 39% of eyes developed vitritis, an inflammation of the eye, which typically resolved within 89 days with appropriate treatment.

Despite the occurrence of inflammation, it did not negatively impact visual outcomes, although monitoring and treatment are essential to prevent potential long-term damage to the retina.

Photodynamic therapy using verteporfin effectively occluded bilateral corneal neovascularization and significantly reduced lipid keratopathy in a 36-year-old patient, leading to improved visual acuity from 20/80 and 20/100 to 20/30 in both eyes over a 4-year follow-up period.

The treatment was safe, with no observed recurrences or complications during the follow-up, suggesting that verteporfin laser therapy is a reliable option for managing corneal neovascularization.

Verteporfin therapy leads to short-lived skin photosensitivity, peaking at 1.5 hours post-treatment and decreasing rapidly, with a duration of 2 to 6.7 days depending on the dose.

In clinical trials, only 2.2% of patients experienced photosensitivity reactions, indicating a low incidence of adverse effects, which could be minimized with proper skin protection following treatment.

Improvements in functional vision, including ambulatory navigation and light sensitivity, were maintained for 3 to 4 years after voretigene neparvovec (VN) treatment in patients with biallelic RPE65 mutation-associated inherited retinal disease, indicating long-term efficacy.

The safety profile of VN was favorable, with no serious adverse events related to the treatment reported, although one patient experienced retinal detachment, which is consistent with risks associated with the injection procedure.

Ranibizumab (Lucentis®) significantly improves visual acuity in patients with macular oedema following retinal vein occlusion, as shown in two phase III trials with monthly injections leading to better outcomes than sham injections at 6 months.

The treatment was generally well tolerated, with adverse events aligning with those seen in other conditions treated with ranibizumab, indicating a favorable safety profile.

Vemurafenib, a BRAF inhibitor used for treating late-stage melanoma with BRAF V600E mutations, can cause various skin reactions, including a rare case of vitiligo, as reported in a 63-year-old patient after 4 weeks of treatment.

The development of vitiligo in this patient was confirmed through clinical examination and advanced imaging techniques, raising questions about whether this adverse reaction could be linked to positive treatment outcomes.

In a phase 2 trial involving patients with vitiligo, those using 1.5% ruxolitinib cream showed a significant improvement in facial Vitiligo Area Scoring Index scores, with a mean improvement of 79.9% at week 24 compared to only 1.1% in those who did not respond.

Proteomic analysis revealed distinct inflammatory biomarker profiles between patients who achieved at least a 50% improvement and those who did not, suggesting that these biomarkers could help identify which patients are more likely to benefit from ruxolitinib treatment.

Excimer light (EL) therapy showed superior repigmenting efficacy in vitiligo patients compared to targeted UVB (TUVB), with 82.6% of EL patients achieving at least 50% repigmentation versus 76.3% in the TUVB group.

Patients receiving EL required fewer treatment sessions and lower cumulative doses to achieve complete or near-complete repigmentation, indicating it may be a more efficient option for vitiligo treatment, with negligible adverse effects reported in both groups.

Is targeted UVB as effective as excimer light phototherapy in treatment of vitiligo? Tabassum, H., Majid, I., Imran, S.[2021]

The combination of apremilast and narrowband UVB therapy significantly reduces immune cell markers (like CD8+ T cells) and enhances melanogenesis markers in vitiligo skin, suggesting a more effective treatment approach than narrowband UVB alone.

This study supports the clinical observation that apremilast can enhance the repigmentation effects of narrowband UVB therapy in patients with generalized vitiligo, particularly in skin types IV-VI, although it was limited by a small sample size and high dropout rate.

A new treatment for vitiligo using hydrogel microneedles to deliver alpha-melanocyte-stimulating hormone (α-MSH) and tofacitinib shows promise in promoting skin and hair pigmentation.

The microneedles effectively penetrate the skin barrier to deliver these agents directly to the epidermis and dermis, resulting in significant melanin deposition and accelerated pigmentation.

In a study involving five patients with non-segmental vitiligo, the addition of heterologous type I collagen (HTIC) to narrowband ultraviolet B (NB-UVB) therapy resulted in a significantly higher mean repigmentation rate of 70.5% after 12 weeks, compared to just 16.5% with NB-UVB alone.

Repigmentation was observed to begin as early as the first treatment session for some patients, indicating that HTIC may provide a more rapid onset of repigmentation when used alongside NB-UVB therapy.
