RESUMO
OBJECTIVES: The characteristics of critically ill HIV-positive patients and the causes of their admission to intensive care units (ICUs) are only known through retrospective and unicentric studies. This study aims to fill this knowledge gap. METHODS: This is a prospective, multicentre cohort study of short- and medium-term prognostic factors. The setting consisted of ICUs of three tertiary referral hospitals from the three largest metropolitan areas in Brazil in the period January 2014 to November 2015. In all, 161 HIV patients over 18 years old were included. RESULTS: The clinical data of the outcomes (ICU mortality, hospital mortality and 90-day survival) were extracted from medical records using the REDCap®ï¸ web-based form and analysed with the MedCalc®ï¸ application. Median age was 41.7 [interquartile range (IQR): 34-50] years, the Simplified Acute Physiologic Score 3 (SAPS 3) was 64 (IQR: 56-74), and the Sequential Organ Failure Assessment Score (SOFA) was 6 (IQR: 4-9) points. The main causes of admission were sepsis (54.5%) and acute respiratory failure (13.7%). ICU and hospital mortality rates were 32.3% and 40.4%, respectively. In a multivariate analysis, time until ICU admission ≥ 3 days (P = 0.0013), performance status (Eastern Cooperative Oncology Group score, P = 0.0344), coma (Glasgow Coma Scale ≤ 8 points, P = 0.0213) and sepsis (P = 0.0003) were associated with increased hospital mortality. Coma (P = 0.0002) and sepsis (P = 0.0008) were independently associated with 90-day survival. CONCLUSIONS: Delayed ICU admission and the severity of critical illness determine the short- and medium-term mortality rates of HIV-infected patients admitted to the ICU, rather than factors associated with HIV infection. These results suggest that prognostic factors of HIV-infected patients in the ICU are similar to those of non-HIV-infected populations.

Biliary atresia is the most common indication for orthotopic liver transplantation (OLT) in children. The polysplenia syndrome anomalies, which occur in approximately 10% of children with biliary atresia, may represent special difficulties at liver transplantation. We have reviewed our experience with this syndrome in 116 children with biliary atresia who underwent liver transplantation between March 1984 and December 1989. The main features of the polysplenia syndrome, which included absence of the inferior vena cava, preduodenal portal vein, midgut malrotation, aberrant hepatic artery, and situs inversus, were encountered in 12 of the 116 children (10.3%). Severe portal vein hypoplasia (3.5 mm or smaller) was also present in 7 of these children. Eight patients received a complete and four received a reduced liver graft. The vascular anomalies increased the technical difficulty of OLT but could be surmounted, although they did contribute to the peroperative death of one child. The 1-month survival rate was 83% for the 12 children with features of the polysplenia syndrome and 88% for the other 92 children with biliary atresia alone.
