We previously described two unrelated patients showing characteristic facial and skeletal features, overlapping with the kyphoscoliosis type Ehlers-Danlos syndrome (EDS) but without lysyl hydroxylase deficiency [Kosho et al. (2005) Am J Med Genet Part A 138A:282-287]. After observations of them over time and encounter with four additional unrelated patients, we have concluded that they represent a new clinically recognizable type of EDS with distinct craniofacial characteristics, multiple congenital contractures, progressive joint and skin laxity, and multisystem fragility-related manifestations. The patients exhibited strikingly similar features according to their age: craniofacial, large fontanelle, hypertelorism, short and downslanting palpebral fissures, blue sclerae, short nose with hypoplastic columella, low-set and rotated ears, high palate, long philtrum, thin vermilion of the upper lip, small mouth, and micro-retrognathia in infancy; slender and asymmetric face with protruding jaw from adolescence; skeletal, congenital contractures of fingers, wrists, and hips, and talipes equinovarus with anomalous insertions of flexor muscles; progressive joint laxity with recurrent dislocations; slender and/or cylindrical fingers and progressive talipes valgus and cavum or planus, with diaphyseal narrowing of phalanges, metacarpals, and metatarsals; pectus deformities; scoliosis or kyphoscoliosis with decreased physiological curvatures of thoracic spines and tall vertebrae; cutaneous, progressive hyperextensibility, bruisability, and fragility with atrophic scars; fine palmar creases in childhood to acrogeria-like prominent wrinkles in adulthood, recurrent subcutaneous infections with fistula formation; cardiovascular, cardiac valve abnormalities, recurrent large subcutaneous hematomas from childhood; gastrointestinal, constipation, diverticula perforation; respiratory, (hemo)pneumothorax; and ophthalmological, strabismus, glaucoma, refractive errors.

Gene expression profiles in laser-induced glaucomatous monkey retinas were determined, and only a very small population of genes was up- or downregulated in glaucomatous eyes. Upregulation of ceruloplasmin protein was found in the Müller cells.

Background Hereditary transthyretin (ATTRv) amyloidosis is a rare, inherited, progressive disease caused by mutations in the transthyretin (TTR) gene. We aimed to assess the efficacy and safety of long-term treatment with patisiran, an RNA interference therapeutic that inhibits TTR production, in patients with ATTRv amyloidosis with polyneuropathy. MethodsThis multi-country, multi-centre, open-label extension (OLE) trial enrolled patients at 43 sites in 19 countries as of 24 September 2018. Patients were eligible if they had completed the phase 3 APOLLO (randomised, double-blind, placebo-controlled [2:1], 18-month study) or phase 2 OLE (single-arm, 24-month study) parent studies and tolerated the study drug. Eligible patients from APOLLO (APOLLO-patisiran [received patisiran during APOLLO] and APOLLO-placebo [received placebo during APOLLO] groups) and the phase 2 OLE (phase 2 OLE patisiran group) studies enrolled in this Global OLE trial and receive patisiran 0•3 mg/kg by intravenous infusion every 3 weeks for up to 5 years. Efficacy assessments include measures of polyneuropathy (modified Neuropathy Impairment Score +7 [mNIS+7]), quality of life, autonomic symptoms, nutritional status, disability, ambulation status, motor function, and cardiac stress. Patients included in the current efficacy analyses are those who had completed 12-month efficacy assessments as of the data cut-off. Safety analyses included all patients who received ≥1 dose of patisiran up to the data cut-off. The Global OLE is ongoing with no new enrolment, and current findings are based on the 12-month interim analysis. The study is registered with ClinicalTrials.gov, NCT02510261.

We conducted a retrospective observational study including 31 eyes of 20 patients in order to investigate the efficacy of 25-gauge vitrectomy for vitreous opacity with minimal conjunctival invasion and subsequent management of intraocular pressure (iop) secondary to hereditary transthyretin amyloidosis. We followed up these patients for an average of 44.7 ± 32.6 months. The primary outcome was best corrected visual acuity (BCVA) at 1 month after surgery and at the final follow-up visit, with management of subsequent IOP elevation. Secondary outcomes included the post-vitrectomy iop survival rate, to determine the frequency of iop elevation requiring glaucoma surgery. Mean age at vitrectomy was 55.4 ± 9.1 years. Logarithm of the Minimum Angle of Resolution (LogMAR) BCVA showed immediate improvement from 0.73 ± 0.62 to 0.00 ± 0.22 at 1 month (p = 4.1 × 10 −7), an improvement that was maintained up to the final follow-up visit, when IOP was maintained at 13.1 ± 5.2 mmHg. The survival rate of post-vitrectomy IOP control was 0.51, 0.38, and 0.23 at 12, 24, and 60 months, respectively. A poor post-vitrectomy IOP survival rate suggests that removing vitreous amyloid via 25-gauge vitrectomy is not sufficient to guarantee good visual function; subsequent careful follow-up and proper glaucoma management is also required in order to achieve this goal.

Purpose: To investigate ocular angiographic features of hereditary transthyretin amyloidosis with transthyretin Val30Met mutation (hATTR-V30M) in Japanese patients.Methods: We retrospectively reviewed 102 eyes of 51 patients with hATTR-V30M who underwent fluorescein angiograms and indocyanine green angiograms between 2012 and 2018. Systemic severity score, fluorescein angiograms, indocyanine green angiograms, and ocular amyloidosis presentations at the final angiograms and subsequent neovascular events were evaluated. Primary outcomes were the frequency of choroidal amyloid angiopathy and retinal amyloid angiopathy (RAA). Secondary outcomes were their correlations to the systemic severity score.Results: Six eyes could not be evaluated by fluorescein angiogram because of vitreous opacity. Of 96 eyes evaluated, RAA was detected in 36 (37.5%). Neovascularization was not detected. Indocyanine green angiogram indicated choroidal amyloid angiopathy in 46/ 51 patients (90.2%), with distinct patterns-diffuse (n = 6), focal (n = 14), and punctiform (n = 26)-based on late-phase hypercyanescence. Retinal amyloid angiopathy and choroidal amyloid angiopathy grades were associated with systemic severity (r = 0.57 and 0.50, respectively; both P , 0.05). At 35.4 ± 28.4 (0-96) months, iris-rubeosis was observed in one eye and vitreous hemorrhage in two.Conclusion: Retinal amyloid angiopathy was less common and choroidal amyloid angiopathy was frequent, and their severity correlated with the systemic severity score. The frequencies of RAA and subsequent neovascular events in this study may suggest regional differences in the ocular angiographic features of hATTR-V30M.
