Individualized dose of anti-thymocyte globulin based on weight and pre-transplantation lymphocyte counts in pediatric patients: a single center experience.

Anti-thymocyte globulin (ATG) has become a standard in preventing GVHD in related and unrelated donor transplantation, but there is no consensus on the best administration schedule. The PARACHUTE trial reported excellent CD4 immune reconstitution (CD4 IR) using a dosing schedule based on the patient's weight and pre-conditioning absolute lymphocyte count (ALC). In 2015 we introduced the PARACHUTE dosing schedule for pediatric patients at our center. One hundred one patients were transplanted for malignant and non-malignant diseases. In this non-concurrent cohort CD4 IR+, defined by a single CD4 count >50/µL on day 90, was seen in 81% of patients. The incidence of grade II-IV and III to IV aGvHD was 26.6% and 15.3% and 5% for cGvHD with no severe cases. We found no difference in aGvHD between donor type and stem cell sources. Five-year EFS and OS were 77.5% and 83.5%. Grade III-IV GFRS was 75.2%. CD4 IR+ patients had better EFS (93.1% vs. 77.7%, p = 0.04) and lower non-relapse mortality (2.7% vs. 22.2%, p = 0.002). The PARACHUTE ATG dosing schedule individualized by weight and ALC results in good early immune reconstitution, low incidence of cGvHD, and favorable survival for patients with different disease groups, donor types, and stem cell sources.

[Monitoring of anticoagulant treatment with Unfractionated Heparin in pediatrics]. / Monitoreo del tratamiento anticoagulante con Heparina no Fraccionada en pediatría.

Unfractionated heparin (UFH) is the most widely used anticoagulant in hospitalized patients. The therapeutic range (TR) was defined in adults according to the prolongation of the activated Partial Thromboplastin Time (aPTT). However, the recommendation is to maintain a therapeutic range with anti-factor Xa assay (antiFXa). As this technique is more complex to perform and less available, it is recommended to make local correlation curves of aPTT with antiFXa. OBJECTIVE: to determine the correlation between the values of aPTT and antiFXa in patients treated with UFH. PATIENTS AND METHOD: 52 patients between 2 days to 14 years of age hospitalized in the Pediatric Critical Patient Unit were recruited. They received treatment with UFH in continuous infusion for at least 24 hours. aPTT and antiFXa tests were performed according to the moment of anticoagulation. To evaluate the concordance of the levels of aPTT with those of antiFXa, the Kappa statistical coefficient of Landis and Koch was used. RESULTS: 105 samples were collected from 52 patients. The overall concordance was 0.452 (moderate correlation). In patients aged < 1 month (n = 40), a considerable correlation was evident (r = 0.617); in those from 1 month to < 6 months (n = 18) and 6 months - < 12 months with aPTT < 120 seconds (n = 11), also showed a considerable correlation (r = 0.636 and 0.615, respec tively), while in those aged > 12 months (n = 37) with aPTT < 120 seconds, a moderate correlation was evident (r = 0.454). CONCLUSION: In our population, there is a moderate correlation between the values of aPTT and antiFXa.

COVID-19 Inspired Relational Telemental Health Services for Incarcerated Individuals and Their Families.

The novel coronavirus pandemic has caused marriage and family therapists (MFTs) to alter how they provide clinical services. MFTs must determine how to deliver relationship-oriented services to underserved populations that are often forgotten during crises, including incarcerated individuals and their families. The primary purpose of this paper is to showcase how relational telemental health (TMH) services for incarcerated individuals and their families can increase access to services and improve relational health. Information is presented about corrections in the U.S., effects of incarceration on partners, children, and other family members, the behavioral health and relationship needs of incarcerated individuals, and current approaches to relational mental health and telehealth in corrections. Finally, suggestions are offered on how relational TMH could be used in corrections during the COVID-19 pandemic, including advocacy for collaborative healthcare, recommended implementation practices, and ethical considerations.

Porfiria eritropoyética congénita: reporte de un caso y recomendaciones de manejo / Congenital erythropoietic porphyria: case report and management recommendations

La porfiria eritropoyética congènita es una porfiria cutánea no aguda, extremadamente poco frecuente, autosómica recesiva, producida por la deficiencia de la enzima uroporfirinógeno III sintetasa codificada en el gen UROS, en el cromosoma 10q26.2. Esto genera el depósito y la acumulación de porfirinas en las córneas, los huesos y los dientes. Se presenta desde los primeros meses de vida con intensa fotosensibilidad, que se manifiesta con fragilidad cutánea con formación de vesículas, bulas y costras. El curso grave lleva a la mutilación de tejidos acrales, compromiso ocular, anemia hemolítica e hiperesplenismo. El manejo es complejo, basado, sobre todo, en la fotoprotección. Un correcto diagnóstico y enfrentamiento puede mejorar notablemente la calidad y expectativas de vida de estos pacientes. Se presenta el caso de un lactante con porfiria eritropoyética congénita confirmada con el estudio genético.

Congenital erythropoietic porphyria is an extremely rare, autosomal recessive, non-acute cutaneous porphyria, caused by uroporphyrinogen III synthase deficiency, codificated by UROS gene on the chromosome 10q26.2. Porphyrins deposit in cornea, bones and teeth. The first symptoms could be manifested in early childhood, with skin fragility, vesicles and bullae. Severe course produces acral tissues mutilation, eye involvement, hemolytic anemia and hypersplenism. The treatment is complex and it is based in the photoprotection. A correct diagnosis can significantly improve the quality and life expectancy of these patients. We present the case of a child with congenital erythropoietic porphyria confirmed by genetic analysis.
