Influence of AIDS antiretroviral therapy on the growth pattern / Influência da terapia antirretroviral para a AIDS no padrão de crescimento

Abstract Objectives: Human immunodeficiency virus infection can result in the early impairment of anthropometric indicators in children and adolescents. However, combined antiretroviral therapy has improved, in addition to the immune response and viral infection, the weight and height development in infected individuals. Therefore, the objective was to evaluate the effect of combined antiretroviral on the growth development of human immunodeficiency virus infected children and adolescents. Source of data: A systematic review was performed. In the study, the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) strategy was used as the eligibility criterion. The MEDLINE-PubMed and LILACS databases were searched using these descriptors: HIV, children, growth, antiretroviral therapy. The objective was defined by the population, intervention, comparison/control, and outcome (PICO) technique. Inclusion and exclusion criteria were applied for study selection. Synthesis of data: Of the 549 studies indexed in MEDLINE-PubMed and LILACS, 73 were read in full, and 44 were included in the review (33 showed a positive impact of combined antiretroviral therapy on weight/height development, ten on weight gain, and one on height gain in children and adolescents infected with human immunodeficiency virus). However, the increase in growth was not enough to normalize the height of infected children when compared to children of the same age and gender without human immunodeficiency virus infection. Conclusions: Combined antiretroviral therapy, which is known to play a role in the improvement of viral and immunological markers, may influence in the weight and height development in children infected with human immunodeficiency virus. The earlier the infection diagnosis and, concomitantly, of malnutrition and the start of combined antiretroviral therapy, the lower the growth impairment when compared to healthy children.

Resumo Objetivos: A infecção pelo vírus da imunodeficiência humana pode comprometer, precocemente, os indicadores antropométricos de crianças e adolescentes. No entanto, a terapia antirretroviral combinada tem melhorado, além da resposta imunológica e da infecção viral, o ganho pôndero-estatural dos infectados. Dessa forma, nosso objetivo foi avaliar o efeito da terapia antirretroviral combinada no crescimento, de crianças e adolescentes, infectadas pelo vírus da imunodeficiência humana. Fonte dos dados: Foi realizada uma revisão sistemática. No estudo, adotou-se como critério de elegibilidade dos artigos, a estratégia PRISMA (preferred reporting items for systematic reviews and meta-analyses). Foram consultadas as bases de dados MEDLINE-PubMed e LILACS pelos descritores: HIV (vírus da imunodeficiência humana), children, growth, antiretroviral therapy. O objetivo foi definido pela estratégia PICO (population, intervention, comparison/control, outcome). Critérios de inclusão e exclusão foram aplicados na seleção dos estudos. Síntese dos dados: Dos 549 estudos indexados no MEDLINE-PubMed e LILACS, 73 foram lidos na íntegra - 44 incluídos na revisão (33 demonstraram impacto positivo da terapia antirretroviral combinada no ganho pôndero-estatural, dez no ganho de peso e um no de estatura, em crianças e adolescentes, infectados com vírus da imunodeficiência humana). No entanto, o incremento no crescimento não foi o suficiente para normalizar a estatura de crianças infectadas, quando comparado com crianças da mesma idade e sexo, sem infecção pelo vírus da imunodeficiência humana. Conclusões: A terapia antirretroviral combinada que, conhecidamente, atua na melhora de marcadores virais e imunológicos, pode influenciar no ganho pôndero-estatural de crianças infectadas com vírus da imunodeficiência humana. Quanto mais precoce o diagnóstico da infecção e, concomitante, desnutrição e início da terapia antirretroviral combinada, menores serão os prejuízos no crescimento, quando comparado às crianças saudáveis.

Lipid profile associated with the systemic inflammatory response syndrome and sepsis in critically ill patients.

OBJECTIVES: Changes in lipid profiles occur in systemic inflammatory response syndrome (SIRS), whether due to sepsis or another cause. Hypocholesterolemia associated with hypertriacylglycerolemia can lead to disease severity and higher mortality. The aim of this systematic review was to describe the principal alterations in markers that participate in the alteration of the lipid profile. METHODS: We reviewed articles focused on alterations in the lipid profile in SIRS, sepsis, or both that were indexed in the Scientific Electronic Library Online from 2000 to 2017. The descriptors used were SIRS; sepsis; lipid profile; and lipoproteins. We focused in particular on the relationships among SIRS, sepsis, and lipid profiles. RESULTS: We included 29 studies that discussed decreased high-density lipoprotein (HDL), total cholesterol, and low-density lipoprotein, and elevated triacylglycerols concentrations in patients with SIRS, sepsis, or both. The variation in the lipid profile was proportional to the level of inflammation as evaluated by inflammatory markers, including C-reactive protein, interleukin-6 and interleukin-8, lipopolysaccharide-binding protein, and tumor necrosis factor. Additionally, there was a change in the composition of lipoproteins, especially HDL, triacylglycerols, and very low-density lipoprotein. HDL appears to be an inflammatory marker, as reduction of its levels reflects the intensity of the underlying inflammatory process. CONCLUSION: Critically ill patients with SIRS, sepsis, or both presented with alterations in lipid metabolism.

Hypercholesterolemia and hypertriglyceridemia as risk factors of liver dysfunction in children with inflammation receiving total parenteral nutrition.

BACKGROUND AND AIMS: Hepatic dysfunction, due to parenteral nutrition, may become severe and lead to cirrhosis and hepatic failure, especially in newborns and infants. This study aimed to evaluate the association between the exclusive use of total parenteral nutrition (TPN) and changes in the hepatic profile, and to investigate the relationship between age, hypertriglyceridemia, and hypercholesterolemia, and the occurrence of laboratory liver dysfunction. METHODS: A descriptive and historical cohort study was conducted, evaluating 195 pediatric patients (age: 1 month to 19 years) who received TPN. The following hepatic and lipid profiles were assessed: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, gamma-glutamyl transferase (GGT), bilirubin, triglycerides (TGs), cholesterol, high-density lipoprotein (HDL), albumin, and transthyretin. High C-reactive protein and/or low HDL were considered indicative of inflammatory process. RESULTS: The majority of patients presented normal values of AST (79.2%), ALT (74.9%), GGT (56.4%), and alkaline phosphatase (68.1%). Total bilirubin changed in 68.5% of patients, and transthyretin and albumin were low in 87.3% and 65.1% of the patients, respectively. Incidences of high GGT values were related to age (odds ratio [OR], 2.46; confidence interval [CI] 1.28-4.76; p = 0.007), hypercholesterolemia (OR, 3.00; 95% CI, 1.24-7.25; p = 0.015), and hypertriglyceridemia (OR, 2.39; 95% CI, 1.02-5.60; p = 0.046). Incidences of elevated ALT values were associated with hypercholesterolemia (OR, 4.57; 95% CI, 2.03-10.30; p < 0.001). CONCLUSION: Monitoring the hepatic profile from the early stage of TPN is necessary. Changes in the plasma lipid and hepatic profiles were frequently observed during the infusion of TPN, in patients with inflammation. Patients >2 years old and those with high TG and HDL levels were more likely to have elevated GGT levels. Hypercholesterolemia was associated with ALT alterations. Strategies to attenuate these issues should be considered in the early stages, in patients with TPN.
