Background: Serum neurofilament light chain (sNfL) and distinct intra-retinal layers are both promising biomarkers of neuro-axonal injury in multiple sclerosis (MS). We aimed to unravel the association of both markers in early MS, having identified that neurofilament has a distinct immunohistochemical expression pattern among intra-retinal layers. Methods: Three-dimensional (3D) spectral domain macular optical coherence tomography scans and sNfL levels were investigated in 156 early MS patients (female/male: 109/47, mean age: 33.3 ± 9.5 years, mean disease duration: 2.0 ± 3.3 years). Out of the whole cohort, 110 patients had no history of optic neuritis (NHON) and 46 patients had a previous history of optic neuritis (HON). In addition, a subgroup of patients ( n = 38) was studied longitudinally over 2 years. Support vector machine analysis was applied to test a regression model for significant changes. Results: In our cohort, HON patients had a thinner outer plexiform layer (OPL) volume compared to NHON patients ( B = −0.016, SE = 0.006, p = 0.013). Higher sNfL levels were significantly associated with thinner OPL volumes in HON patients ( B = −6.734, SE = 2.514, p = 0.011). This finding was corroborated in the longitudinal subanalysis by the association of higher sNfL levels with OPL atrophy ( B = 5.974, SE = 2.420, p = 0.019). sNfL levels were 75.7% accurate at predicting OPL volume in the supervised machine learning. Conclusions: In summary, sNfL levels were a good predictor of future outer retinal thinning in MS. Changes within the neurofilament-rich OPL could be considered as an additional retinal marker linked to MS neurodegeneration.

Close anatomical connection between the optic nerve and the posterior nasal appendages and the commonality of their circulatory system explain optic nerve lesions in purulent and catarrhal processes in the posterior sinuses. N.A. Khristianov describes a case of left-sided retrobulbar optic neuritis cured by opening the middle and posterior lattices of the same side, affected by chronic catarrh.

Introduction: Transient abnormal myelopoiesis (TAM) in neonates with Down syndrome (DS) is characterized by the transient appearance of blast cells that harbor somatic GATA1 gene mutation. Although most patients show spontaneously resolution without therapeutic interventions, approximately 20% of TAM cases result in early deaths within 9 months and 20% of survivors develop acute megakaryoblastic leukemia (AMKL) within 4 years. Although the risk factors associated with early deaths are known, the definite clinical predictive indicators of AMKL onset in patients with TAM remain unclear. Therefore, we analyzed 167 TAM patients with DS enrolled in the TAM-10 prospective observational study conducted by the Japan Pediatric Leukemia/Lymphoma Study Group (JPLSG) to determine the clinical characteristics of TAM and predictive factors of leukemia development. Patients and Methods: Between May 2011 and February 2014, 167 neonates (89 boys and 78 girls) diagnosed with TAM were prospectively registered in the TAM-10 study. Somatic GATA1 gene mutations were confirmed in 163 (98%) patients using Sanger and/or next-generation sequencing. Minimal residual disease using flow cytometry (FCM-MRD; cut-off level, ≥0.1%) was monitored at 1 (n = 133) and 3 months (n = 104). Results: Median (range) gestational age, birth body weight, white blood cell (WBC) count, and percentage of blasts at diagnosis were 37 (29-40) weeks, 2,612 (1,066-3714) g, 38.3 (2.4-478.7) × 109 cells/L, and 37% (0.5%-95.5%), respectively. Systemic edema and organ hemorrhage was observed in 31/167 (19%) and 14/167 (8%) patients, respectively; 68/167 (41%) patients received some therapeutic interventions, including low-dose cytarabine (LDCA; n = 52), exchange blood transfusion (n = 20), and systemic steroid therapy (n = 31). Early death (<9 months of age) occurred in 22/167 (13%) patients. In multivariate analysis, early death was significantly associated with a high WBC count [≥100 × 109 cells/L; HR (95% CI) = 5.329 (2.194-12.945), P < 0.001] and systemic edema [HR (95% CI) = 8.073 (3.130-20.823), P < 0.001]. Subgroup analysis in patients with such high WBC count (n = 36) showed that LDCA therapy significantly improved survival [1-year OS (95% CI) = 78.3% (55.4-90.3; n = 23) vs. 38.5% (14.1-62.8; n = 13); P = 0.009]. Among 145/167 patients without early death, 28 (19%) developed AMKL. FCM-MRD positivity at 1 month [positive, n = 107; negative, n = 26; cumulative incidence ratio (CIR) (95% CI) = 25.2% (17.3-33.9%) vs 3.8% (0.3%-16.8%), P = 0.022] and 3 months (positive, n = 20; negative, n = 84; CIR (95% CI), 45.0% (22.3%-65.4%) vs. 16.0% (9.0%-24.8%), P = 0.002] was significantly associated with leukemia development. However, other clinical covariates, including sex, birth weight, gestational age, WBC count, blast percentage, and GATA1 gene mutational types, could not predict AMKL development. Considering their severe clinical conditions, 13/31 (42%) patients who received systemic steroid therapy died before AMKL development; interestingly, none of the remaining 18 patients developed AMKL but they showed significantly lower CIR than those who did not receive this therapy [CIR (95% CI), 0% vs. 19.4% (10.9%-29.6%), P = 0.010]. Other therapeutic interventions, including LDCA and exchange blood transfusion, were not associated with AMKL development. Conclusion: FCM-MRD positivity at 1 month and 3 months might be a useful marker to predict leukemia development in patients with TAM. Although LDCA therapy significantly decreased the rate of early deaths, it did not suppress leukemia development. Interestingly, systemic steroid therapy might suppress leukemia development. These results pave the way to design clinical trials for developing MRD-directed leukemia prevention therapy for patients with TAM. Disclosures No relevant conflicts of interest to declare.

AbstractPlants alter chemical and physical properties of soil, and thereby influence rhizosphere microbial community structure. The structure of microbial communities may in turn affect plant performance. Yet, outside of simple systems with pairwise interacting partners, the plant genetic pathways that influence microbial community structure remain largely unknown, as are the performance feedbacks of microbial communities selected by the host plant genotype. We investigated the role of the plant circadian clock in shaping rhizosphere community structure and function. We performed 16S rRNA gene sequencing to characterize rhizosphere bacterial communities of Arabidopsis thaliana between day and night time points, and tested for differences in community structure between wild-type (Ws) vs. clock mutant (toc1-21, ztl-30) genotypes. We then characterized microbial community function, by growing wild-type plants in soils with an overstory history of Ws, toc1-21 or ztl-30 and measuring plant performance. We observed that rhizosphere community structure varied between day and night time points, and clock misfunction significantly altered rhizosphere communities. Finally, wild-type plants germinated earlier and were larger when inoculated with soils having an overstory history of wild-type in comparison to clock mutant genotypes. Our findings suggest the circadian clock of the plant host influences rhizosphere community structure and function.
