    Abstract Background: CMV remains a frequent complication after liver transplantation. Few studies exist in children reporting the epidemiology and outcomes of CMV after LT with current prevention strategies. Our goal is to report the incidence of CMV infection and disease in pediatric LT recipients under preemptive therapy, identify risk factors, complications, and adverse reactions to treatment.
    Methods: All pediatric LT recipients from a single center (1998-2018) were included. Antigenemia pp65 (1998-2003) and QNAT or both were used to inform preemptive therapy. Cutoff value for starting treatment was Agpp65 > 10 + cells/200 000 or QNAT >1500 copies/ml or any value in high-risk recipients (D+/R-).
    Results: One hundred eighteen LT were analyzed. CMV infection was detected in 67% of patients, only 44 (37%) required treatment, and 5 (4%) developed CMV disease. All patients responded well to treatment, and no graft or patients were lost to CMV effects. There were no differences in mortality, CMV indirect effects, or other complications between those who required treatment and those who did not. Thirty-two percent of the patients who received antivirals developed an adverse hematological reaction. Risk factors associated with CMV infection requiring treatment were D+/R- (OR 13.9, p = .01) and fulminant hepatitis (OR 4.8, p = .02).
    Conclusions: Preemptive therapy for CMV in children is safe and effective, yields low CMV infection rates that require treatment, and minimal rates of CMV disease, without increasing CMV-related complications. Using this strategy, 63% of our patients did not receive treatment. Therefore, drug exposure, adverse reactions, and resistance risk were minimized.

    Abstract The prevention and management of cytomegalovirus (CMV) remain challenging in children who have undergone solid organ transplantation, despite the availability of effective antiviral medications and sensitive diagnostic assays. The primary objective of this invited commentary is to provide an updated and multidisciplinary approach to persistently challenging CMV cases that commonly occur in pediatric transplantation candidates and recipients, including cases for which published data are frequently lacking.

    Abstract This multicenter, open-label study evaluated the tolerability of extended prophylaxis with valganciclovir in pediatric kidney transplant recipients at risk of CMV disease. Fifty-six patients aged 4 months to 16 years received once-daily valganciclovir oral solution and/or tablets, dosed by BSA and renal function, for up to 200 days. The most common AEs on treatment were upper respiratory tract infection (33.9%), urinary tract infection (33.9%), diarrhea (32.1%), leukopenia (25.0%), neutropenia (23.2%), and headache (21.4%). There were fewer AEs during days 101-228 vs days 1-100. Twenty-seven patients (48.2%) had treatment-related AEs during valganciclovir treatment, most commonly leukopenia (21.4%), neutropenia (19.6%), anemia (7.1%), and tremor (5.4%). Treatment-related serious AEs were reported for nine patients (16.1%) and six withdrew due to AEs. Viremia was centrally confirmed in 10 patients; there was no confirmed CMV disease. One patient tested positive for a resistance mutation (UL97 L595F). Biopsy-proven acute rejection occurred in six patients (10.7%), but no graft loss or deaths occurred. In conclusion, up to 200 days of valganciclovir prophylaxis in pediatric kidney allograft recipients showed a safety profile consistent with that established in adult transplant patients.

    Abstract Background: Tyrosinemia type 1 (HT1, MIM#276700) is caused by a deficiency in fumarylacetoacetate hydrolase (FAH) and it is associated with severe liver and renal disfunction. At present, the mutational FAH (15q25.1, MIM*613871) spectrum underlying HT1 in the Mexican population is unknown. The objective of this study was to determine the FAH genotypes in eight nonrelated Mexican patients with HT1, who were diagnosed clinically.
    Methods: Sequencing of FAH and their exon-intron boundaries and in silico protein modeling based on the crystallographic structure of mouse FAH.
    Results: We identified pathogenic variants in 15/16 studied alleles (93.8%). Nine different variants were found. The most commonly detected HT1-causing allele was NM_000137.2(FAH):c.3G > A or p.(?) [rs766882348] (25%, n = 4/16). We also identified a novel missense variant NM_000137.2(FAH):c.36C > A or p.(Phe12Leu) in a homozygous patient with an early and fatal acute form. The latter was classified as a likely pathogenic variant and in silico protein modeling showed that Phe-12 residue substitution for Leu, produces a repulsion in all possible Leu rotamers, which in turn would lead to a destabilization of the protein structure and possible loss-of-function.
    Conclusion: HT1 patients had a heterogeneous mutational and clinical spectrum and no genotype-phenotype correlation could be established.

    Abstract Background: CYP3A5 gene polymorphism rs776746 has been associated with lower tacrolimus dose requirements and bioavailability in both adults and children. This variant causes a loss of CYP3A5 activity owing to a splice site variant leading to a truncated inactive enzyme. The aim of this study was to determine if the rs776746 gene polymorphism is related to the time to reach tacrolimus therapeutic levels in renal transplant children.
    Methods: A prospective study was performed in renal transplant children receiving tacrolimus as part of their immunosuppressive regime. CYP3A5 genotype was determined by direct sequencing. Tacrolimus trough levels and serum creatinine at 1 week and 1 month after renal transplantation was obtained from clinical chart.
    Results: A total of 42 patients were included; 19 (45.2%) were female, 23 (54.8%) received living-donor transplants, and 21 patients expressed CYP3A5*1/*1 or CYP3A5*1/*3. Tacrolimus dose was higher in expressers at week 1 (0.13 vs 0.10 mg/kg/d; P = .011), and week 4 after transplantation (0.17 vs 0.09 mg/kg/d; P < .0001). At 4 weeks after renal transplantation, only 9 patients from the expressers group (42.8%) had levels ≥7 ng/mL, in contrast to 18 in the nonexpressers group (85.7%; Fisher exact P = .008).
    Conclusions: Tacrolimus dose was significant higher in functional CYP3A5 expressers. Only 42.8% of such expressers had tacrolimus trough levels ≥7 ng/mL at 1 month after transplantation despite dose adjustments. Long-term follow up is needed to address the consequences of early post-transplantation bioavailability differences due to CYP3A5 genotype.

    Abstract Herpesviruses are common components of the human microbiome that become clinically relevant when a competent immunosurveillance is compromised, such as in transplantation. Members of the beta and gamma subfamilies are associated with a wide diversity of pathologies, including end-organ disease and cancer. In this study, we developed a multiplex qPCR technique with high specificity, sensitivity, efficiency and predictability that allowed the simultaneous detection and quantification of beta and gamma human herpesviruses. The technique was tested in a cohort of 34 kidney- or liver-transplanted pediatric patients followed up for up to 12 months post-transplant. Viral load was determined in 495 leukocyte-plasma paired samples collected bi-weekly or monthly. Human herpesvirus (HHV) 7 was the herpesvirus most frequently found in positive samples (39%), followed by Epstein-Barr virus (EBV) (20%). Also, EBV and HHV7 were present in the majority of coinfection episodes (62%). The share of positive samples exclusively detected either in leukocytes or plasma was 85%, suggesting that these herpesviruses tended to take a latent or lytic path in an exclusive manner. Infection by human cytomegalovirus (HCMV) and HHV6, as well as coinfection by EBV/HHV7 and EBV/HHV6/HHV7, were associated with graft rejection (RR = 40.33 (

    Abstract Background: Hereditary actin-related protein 2/3 complex subunit 1B deficiency is characterized clinically by ear, skin, and lung infections, bleeding, eczema, food allergy, asthma, skin vasculitis, colitis, arthritis, short stature, and lymphadenopathy.
    Objective: We aimed to describe the clinical, laboratory, and genetic features of six patients from four Mexican families.
    Methods: We performed exome sequencing in patients of four families with suspected actinopathy, collected their data from medical records, and reviewed the literature for reports of other patients with actin-related protein 2/3 complex subunit 1B deficiency.
    Results: Six patients from four families were included. All had recurrent infections, mainly bacterial pneumonia, and cellulitis. A total of 67% had eczema whereas 50% had food allergies, failure to thrive, hepatomegaly, and bleeding. Eosinophilia was found in all; 84% had thrombocytopenia, 67% had abnormal-size platelets and anemia. Serum levels of IgG, IgA, and IgE were highly increased in most; IgM was normal or low. T cells were decreased in 67% of patients, whereas B and NK cells were increased in half of patients. Two of the four probands had compound heterozygous variants. One patient was successfully transplanted. We identified 28 other patients whose most prevalent features were eczema, recurrent infections, failure to thrive, bleeding, diarrhea, allergies, vasculitis, eosinophilia, platelet abnormalities, high IgE/IgA, low T cells, and high B cells.
    Conclusion: Actin-related protein 2/3 complex subunit 1B deficiency has a variable and heterogeneous clinical spectrum, expanded by these cases to include keloid scars and Epstein-Barr virus chronic hepatitis. A novel deletion in exon 8 was shared by three unrelated families and might be the result of a founder effect.

    Abstract Introduction: Survival of transplant patients and grafts depends largely on the use of immunosuppressive drugs. However, a balance remains to be established among immunosuppression, transplant rejection and cytomegalovirus (CMV) infection, which results in a high rate of morbidity and mortality. The aim of this study was to define a better strategy for monitoring transplanted patients based on the analysis of the blood concentration of sirolimus and tacrolimus and the burden of CMV.
    Methods: Fifty five post-transplant (kidney and liver) pediatric patients, nine treated with sirolimus and 46 treated with tacrolimus, were included. A total of 541 measurements were obtained. In each measurement the concentration of immunosuppressant in whole blood and CMV viral load in plasma and whole blood was quantified by real-time PCR. Pearson correlation coefficient (r) was estimated.
    Results: Values of r ≤0.0747 were found for the relationship between dose and concentration of immunosuppressant; r = 0.9406 for the relationship between viral load in whole blood and plasma, and r ≤0.4616 for the relationship between concentration of immunosuppressant and viral load.
    Conclusions: These data support that the doses of immunosuppressive drugs do not correlate with the levels of the same in whole blood. Therefore, systemic levels of immunosuppressant should be constantly monitored together with CMV load. Meanwhile, a high correlation between viral load measured in whole blood and plasma was found.
