Accelerated Immunodeficiency-associated Vaccine-derived Poliovirus Serotype 3 Sequence Evolution Rate in an 11-week-old Boy With X-linked Agammaglobulinemia and Perinatal Human Immunodeficiency Virus Exposure.

ABSTRACT: Primary B-cell immunodeficiencies are risk factors for the generation of vaccine-derived polioviruses. We report immunodeficiency-associated vaccine-derived poliovirus serotype 3 in an 11-week-old boy with X-linked agammaglobulinemia. Unique characteristics of this case include early age of presentation, high viral evolutionary rate, and the child's perinatal exposure to human immunodeficiency virus.

Project description:Background Hypercalcemic crisis caused by primary hyperparathyroidism (PHPT) in pediatric patients is very rare, and appropriate treatment approach for this condition has not been well demonstrated. Here, we report a case of PHPT-induced hypercalcemic crisis in a boy. Case Description An 11-year-old boy visited the clinic with abdominal pain and nausea that lasted for 3 months, but the cause of his symptoms could not be identified. As these symptoms worsened after 1 month, he was referred to a nearby hospital. The boy’s albumin-corrected serum calcium level was very high (14.3 mg/dL). Treatment was immediately started with the administration of normal saline, furosemide, and calcitonin to lower his serum calcium levels. Based on elevated intact-parathyroid hormone (i-PTH) (405 pg/mL) level and enlargement of the right superior parathyroid on diagnostic imaging, he was diagnosed with hypercalcemic crisis due to PHPT. As his albumin-corrected serum calcium level increased to 16.5 mg/dL and he could not take almost any foods due to severe nausea, he was transferred to our hospital and treated with pamidronate. Although his albumin-corrected serum calcium level decreased to 14.0 mg/dL, his symptoms did not improve completely. Therefore, 2 days after transfer to our hospital, he underwent emergency surgery to resect the enlarged right superior parathyroid gland. Fifteen minutes after removal of the enlarged parathyroid gland, the serum intact-PTH level decreased to 41.7 pg/mL. The histopathological diagnosis of the enlarged parathyroid gland was adenoma. The boy became asymptomatic, and his albumin-corrected serum calcium level was maintained within the normal limits for 6 months post operatively. Genetic testing performed after the surgery did not detect any pathogenic mutations in the MEN1 and CDC73 genes, and no genetic predisposition has been identified to date. Conclusions Emergency focused parathyroidectomy prior to genetic testing might be an appropriate strategy when the pediatric patient presents with a PHPT-induced hypercalcemic crisis.

Project description:IntroductionPhthalates are a group of high production chemicals, generally used as plasticizers and odor enhancers. Phthalates cross the blood-placenta barrier and are associated with deficits in cognitive functions and behavior problems in offspring. We previously reported sex-specific associations with motor function when phthalates are considered singly. Because exposure to phthalates usually occurs as mixtures, here we assess these associations between a mixture of phthalates and motor function at age 11 years.MethodsData come from the prospective cohort study of mothers and offspring who participated in the Columbia Center for Children's Environmental Health birth cohort (CCCEH). Seven phthalate metabolites were measured in maternal spot urine obtained during the third trimester and motor function was evaluated using the short form of the Bruininks-Oseretsky Test of Motor Proficiency, 2nd edition (BOT-2) at the age of 11 years. We used Weighted Quartile Sum (WQS) regression models to examine the effect of phthalate metabolites in males and females separately. The models were adjusted for child age in months, child BMI, maternal race (African-American vs. Dominican), prenatal alcohol consumption, maternal demoralization score, HOME score, and urine specific gravity. In a secondary analysis we used linear regression models to examine the association between the sum of molar concentrations of both DEHP and non-DEHP metabolites, and outcomes of gross and fine motor functions.Results209 mother-child pairs were eligible for this analysis. A significant decrease in fine-motor functions was observed among females, but not among males, following exposure to high levels of weighted quartile sum of seven phthalate metabolites (Covariates-adjusted coefficient estimate B = -2.7, 95% Confidence Interval [CI] -4.64 to -0.75, p = 0.01 for females [n = 116] and B = -1.63, 95%CI -3.94 to 0.69, p = 0.16 for males [n = 93]). The most highly weighted phthalate metabolites, associated with fine-motor functions among females, were MBP, MBZP, and MIBP, all non-DEHP phthalates. No significant associations were found between the weighted quartile sum of seven phthalate metabolites and gross-motor functions at the age of 11 years for males (B = -0.81, 95%CI -1.17 to 1.96, p = 0.23). With the molar sum of four non-DEHP phthalates as main predictor of linear regression models, we found significant decrease in gross and fine motor functions among females prenatally exposed to non-DEHP phthalates B = -0.98, 95%CI -1.98 to 0.03, p = 0.05 and B = -0.85, 95%CI -1.49 to -0.20, p = 0.01, respectively).ConclusionsPhthalate exposure during pregnancy was associated with decreased motor functions among 11-year-old girls.

Project description:BackgroundVaccine-associated paralytic poliomyelitis (VAPP) and immunodeficient long-term polio excretors constitute a significant public health burden and are a major concern for the WHO global polio eradication endgame.Case presentationPoliovirus type 3 characterized as Sabin-like was isolated from a 5-month-old Albanian child with X-linked agammaglobulinemia and VAPP after oral polio vaccine administration. Diagnostic workup and treatment were performed in Italy. Poliovirus replicated in the gut for 7 months. The 5' non coding region (NCR), VP1, VP3 capsid proteins and the 3D polymerase genomic regions of sequential isolates were sequenced. Increasing accumulation of nucleotide mutations in the VP1 region was detected over time, reaching 1.0 % of genome variation with respect to the Sabin reference strain, which is the threshold that defines a vaccine-derived poliovirus (VDPV). We identified mutations in the 5'NCR and VP3 regions that are associated with reversion to neurovirulence. Despite this, all isolates were characterized as Sabin-like. Several amino acid mutations were identified in the VP1 region, probably involved in growth adaptation and viral persistence in the human gut. Intertypic recombination with Sabin type 2 polio in the 3D polymerase region, possibly associated with increased virus transmissibility, was found in all isolates. Gamma-globulin replacement therapy led to viral clearance and neurological improvement, preventing the occurrence of persistent immunodeficiency-related VDPV.ConclusionsThis is the first case of VAPP in an immunodeficient child detected in Albania through the Acute Flaccid Paralysis surveillance system and the first investigated case of vaccine associated poliomyelitis in Italy since the introduction of an all-Salk schedule in 2002. We discuss over the biological and clinical implications in the context of the Global Polio Eradication Program and emphasize on the importance of the Acute Flaccid Paralysis surveillance.
