Haploidentical Stem Cell Transplantation in Children with Benign Disorders: Improved Survival and Cost-Effective Care Over 15 Years from a Single Center in India

We present our experience in haploidentical stem cell transplantation (haplo SCT) in children with benign disorders. We performed a retrospective study where children aged up to 18  years diagnosed to have benign disorders and underwent haplo SCT from 2002 to September 2017 were included. Of the 54 children, the most common indications were Fanconi anaemia 12 (22%), severe aplastic anaemia 8 (14%) and primary immune deficiency disorders (PID) 25 (46%). Post-transplant cycloph osphamide (PTCy) was used in 41 (75.9%) and ex vivo T depletion in 13 (24.1%). Engraftment rates were 70% with acute graft versus host disease in 36% and cytomegalovirus reactivation in 55% children. There was a statistically significant difference found between survival with siblings as donors as c ompared to parents (p value 0.018). Overall survival was 60% which is the 1-year survival, with 68% survival among those with PIDs. Cytokine release syndrome was noted in 12/41 (29%) of children who received T replete graft and PTCy. In children over 6  months of age, PTCy at a cost of INR 1200 provides cost effective T cell depletion comparable with TCR α/β depletion priced at INR 1200,000. Haplo SCT is feasible option for cure in children with benign disorder.

Authors: Vargas-Machuca R, Rojas-Dávila CE, Jiménez MM, Piscoya-Magallanes CR, Razuri H, Ugaz ME Abstract The high level of Venezuelan migration is a great challenge for Peru due to the healthcare needs of immigrants. Worryingly, children under the age of five are the most vulnerable. In order to know the nutritional status of this group in migratory transit to Peru, a descriptive study was carried out with two rounds of data collection (August 2018 and March 2019) at the Binational Border Healthcare Center in Tumbes. In each round, nutritional status, morbidity and food characteristics were determine...

Today's open access research on tryptophan and its role in age-related immune dysfunction is particularly interesting in the context of ongoing research into the changes that take place in gut microbiota with age. Other recent work has examined the way in which tryptophan production by gut microbes declines precipitously with age, as this is one of a number of compounds produced by bacteria, such as butyrate, indole, and proprionate, that are influential on long term health. It is a slow process, but researchers are uncovering the specific mechanisms linking age-related changes in gut microbe populations with declining hea...

This article reviews the potential role of exosomes in OA regenerative medicine. Special attention is given to mesenchymal stem cells-derived exosomes due to the extensive research on their cartilage repair property and their function as miRNA cargo. More investigations are needed for the effects of exosomes from synovial fluid and chondrocytes in joints. A better understanding of the mechanisms will contribute to a novel and promising therapy for OA patients.

Purpose: To determine the factors responsible for the recurrence of infection after therapeutic penetrating keratoplasty (TPK) in severe microbial keratitis. Methods: This is a retrospective interventional case series that reviewed the medical records of 229 consecutive patients (2005–2017) who underwent TPK for microbial keratitis at a tertiary eye care center in Central India. The primary outcome was recurrence of the primary infection. The factors responsible for recurrence were identified by univariate and multivariate regression analysis. Results: The overall outcomes were clear graft in 50 (21.8%) eyes,...

Conclusions: DM suturing can reattach DM, especially in moderate to severe, recurrent DMD with fewer postoperative complications and thereby reduce the need for corneal transplantation.

Conclusions: Tear lipids are more ordered than meibum lipids, which could have functional consequences. The human meibum peak height ratio of the CH3/CH2 bands is not a factor related to tear film stability with age or sex. The amount of CH3 moieties relative to CH2 moieties and saturation could contribute to a higher meibum lipid order associated with a younger age, meibomian gland dysfunction, and dry eye from hematopoietic stem cell transplantation. Therefore, the hydrocarbon order may be a marker of or contribute to an unstable tear film layer.
