Coenzyme Q10 and immunity: A case report and new implications for treatment of recurrent infections in metabolic diseases.

Coenzyme Q10 (CoQ10) deficiency can manifest diversely, from isolated myopathy to multisystem involvement. Immune dysregulation has not been reported as a feature of the disease. We report a four-year old girl with failure to thrive, recurrent infections, developmental delay with hypotonia, and CoQ10 deficiency with impaired immune function, which improved after CoQ10 and immunoglobulin replacement therapy.

Omental infarction: risk factors in children.

Purpose: A series of 4 cases of omental infarction are analyzed. It is shown that obesity, as well as idiosyncratic anatomy, are factors in the development of this rare clinicopathologic entity.

Methods: The authors reviewed the preoperative and operative records of all patients.

Evidence for an innate immune response in the immature human intestine: toll-like receptors on fetal enterocytes.

The intestinal epithelium is an active participant in the mucosal immune response against luminal pathogens. Microorganisms and their cell wall products, i.e.

Inflammation in the developing human intestine: A possible pathophysiologic contribution to necrotizing enterocolitis.

Necrotizing enterocolitis (NEC), a major cause of morbidity and mortality in premature infants, occurs after the introduction of oral feedings in conjunction with initial bacterial colonization of the gut and is hypothesized to be due to an immature (inappropriate) enterocyte response to bacterial stimuli. To test this hypothesis, we compared the enterocyte IL-8 response to inflammatory stimuli [lipopolysaccharide (LPS) and IL-1beta] in immature vs. mature human small intestine.
