ObjectiveTo assess the prevalence, characteristics and prognostic value of pulmonary hypertension (PH) and right ventricular dysfunction (RVD) in hospitalised, non-intensive care unit (ICU) patients with coronavirus disease 2019 (COVID-19).MethodsThis single-centre, observational, cross-sectional study included 211 patients with COVID-19 admitted to non-ICU departments who underwent a single transthoracic echocardiography (TTE). Patients with poor acoustic window (n=11) were excluded. Clinical, imaging, laboratory and TTE findings were compared in patients with versus without PH (estimated systolic pulmonary artery pressure >35 mm Hg) and with versus without RVD (tricuspid annular plane systolic excursion <17 mm or S wave <9.5 cm/s). The primary endpoint was in-hospital death or ICU admission.ResultsA total of 200 patients were included in the final analysis (median age 62 (IQR 52–74) years, 65.5% men). The prevalence of PH and RVD was 12.0% (24/200) and 14.5% (29/200), respectively. Patients with PH were older and had a higher burden of pre-existing cardiac comorbidities and signs of more severe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (radiological lung involvement, laboratory findings and oxygenation status) compared with those without PH. Conversely, patients with RVD had a higher burden of pre-existing cardiac comorbidities but no evidence of more severe SARS-CoV-2 infection compared with those without RVD. The presence of PH was associated with a higher rate of in-hospital death or ICU admission (41.7 vs 8.5%, p<0.001), while the presence of RVD was not (17.2 vs 11.7%, p=0.404).ConclusionsAmong hospitalised non-ICU patients with COVID-19, PH (and not RVD) was associated with signs of more severe COVID-19 and with worse in-hospital clinical outcome.Trial registration numberNCT04318366
Hepatic injury secondary to warm ischemia-reperfusion (I/R) injury and alterations in haemostatic parameters are often unavoidable events after major hepatic resection. The release of inflammatory mediator is believed to play a significant role in the genesis of these events. It has been suggested that preoperative steroid administration may reduce I/R injury and improve several aspects of the surgical stress response. The aim of this prospective randomized study was to investigate the clinical benefits on I/R injury and systemic responses of preoperatively administered corticosteroids. Seventy-six patients undergoing liver resection were randomized either to a steroid group or to a control group. Patients in the steroid group received preoperatively 500 mg of methylprednisolone. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, coagulation parameters, and inflammatory mediators, interleukin 6 and tumor necrosis factor alpha were compared between the 2 groups. Length of stay, and type and number of complications were recorded as well. Postoperative serum levels of ALT, AST, total bilirubin, and inflammatory cytokines were significantly lower in the steroid than in the control group at postoperative days 1 and 2. Changes in hemostatic parameters were also significantly attenuated in the steroid group. In conclusion, the incidence of postoperative complications in the steroid group tended to be significantly lower than the control group. It is of clinical interest that preoperative steroids administration before major surgery may reduce I/R injury, maintain coagulant/anticoagulant homeostasis, and reduce postoperative complications by modulating the inflammatory response. The human body reacts to surgical stimuli through various systemic responses including the endocrine, metabolic, coagulation, and immune systems. However, extended damage may result in an exaggerated systemic response with an overwhelming activation of immune cells and the release of various mediators of stress. [1][2][3] The systemic reaction to the operation is considered to be equivalent to the systemic inflammation response syndrome, mainly caused by cytokine networks. 4,5 Raised levels of inflammatory cytokines have been related to higher postoperative mortality and morbidity rates. 2,3,6 Therefore, increased attention has evolved toward modulating potentially deleterious inflammatory response to the operation.The anti-inflammatory and immune modulating effects of steroids have been known for decades and have found extensive therapeutic use in a wide range of diseases in which inflammatory responses play major role. 7,8 Several trials have investigated the benefits of administering corticosteroids as a modulator of cytokine response in patients undergoing elective cardiothoracic or gastrointestinal surgery, as well as in cases of septic shock, suggesting that several aspects of the surgical stress responses, organ dysfunction, and postAbbreviations: POD, postoperative day; ALT, alanine aminotr...
SD appears to be a common side-effect of HAART regimens containing a PI. The potential association between SD and other side-effects of HAART, such as lipodystrophy syndrome and neuropathy, should be investigated further.
The aim of this retrospective study was to evaluate the influence of age on the outcome of liver resection. A total of 129 consecutive liver resections were divided into two groups: > or = 70 years old [old group (O-group)] and < 70 years old [young group (Y-group)]. The two groups were first compared for the variables potentially affecting the postoperative course, including diagnosis, concomitant diseases, previous abdominal surgery, type of operation (major or minor resection), associated procedures, presence and length of portal clamping, intraoperative blood losses and transfusions, and length of operation. The outcome of liver resections was evaluated in terms of postoperative mortality, morbidity, transfusions, and length of hospitalization. The Y-group included 97 resections in 95 patients, aged 55.9 +/- 10.5 years (mean +/- SD; range: 23-69 years), and the O-group included 32 resections in 32 patients, aged 73.7 +/- 3.2 years (mean +/- SD; range: 70-82 years. The O-group included more hepatocellular carcinomas (46.9% versus 20.6%, p = 0.002) and cardiovascular diseases (15.2% versus 1.0%, p = 0.004). The two groups were comparable (p > 0.05) when evaluated for all other listed variables. As regards the postoperative outcome, the length of hospitalization was similar (median, range: 9.5 days, 5-60 days in the Y-group and 9 days, 5-48 days in the O-group) and the need for postoperative transfusions were not statistically different. Mortality included one case among young patients, while no deaths were recorded among elderly patients. Postoperative morbidity was higher in Y-group than in O-group (21.6% versus 9.4%, p = 0.2). In conclusion, the age factor does not negatively affect the outcome of liver resections.
