Two children were weaned from long-term tube feeding after liver transplant because of Alagille syndrome. The children were successfully weaned, one in seven days and the other in 13 days, using our standard and highly specialized intensive treatment protocol. Normal feeding behavior and stabilization of body weight were established. Children fed by long-term enteral tubes can be weaned from enteral feeding even after a long period of treatment. The return to age-appropriate self-feeding should be introduced as early as possible. Our weaning program time is brief and effective and can be recommended generally to improve quality of life and withhold unintended side-effects of enteral nutrition.
Macrophage inflammatory protein-1alpha (MIP-1alpha) is an interesting chemokine because in addition to its variety proinflammatory activities including chemotaxis and immunomodulation, it is a potent inhibitor of hematopoetic stem cell proliferation. Inhibition of erythroid progenitor cells due to MIP-1alpha or other cytokines can play a role in the pathogenesis of anemia which is one of the most common extra-articular features of active rheumatoid arthritis (RA). In 84 patients with RA, serological and immunological parameters were assessed to detect inflammatory mechanisms and anemia in relation to the serum concentrations of MIP-1alpha. All patients fulfilled the ACR criteria for the diagnosis of a definite or classic RA. We used a quantitative enzyme immuno assay for the detection of MIP-1alpha as well as for the measurement of the acute phase protein serum amyloid A (SAA), the erythropoiesis inducer erythropoietin (EPO) and the transferrin receptor (TfR). The immune activation marker neopterin was measured radioimmunologically. Half of the patients with RA were anemic with hemoglobin values below 12 g/dl. MIP-1alpha was found to be elevated significantly in serum of patients with active rheumatoid arthritis and in patients with anemia. Most of the anemic patients with markedly elevated acute phase reactions had an anemia with chronic diseases and not a functional iron deficiency alone. TfR correlated with EPO. The results show that enhanced expression of MIP-1alpha is indicative of systemic inflammation in RA. Moreover, besides the regulation of inflammatory processes, this chemokine may influence the pathogenesis of anemia in RA patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
