RESUMEN
BACKGROUND: Severe mental illnesses are risk factors for SARS-CoV-2-related morbidity and mortality. Vaccination is an effective protection; therefore, high vaccination rates should be a major priority for people with mental illnesses. OBJECTIVES: (1) Identification of at-risk groups for non-vaccination and structures and interventions needed for widespread vaccination among people with mental illnesses from the perspective of outpatient psychiatrists and neurologists, (2) discussion of the results in the context of the international literature and (3) recommendations derived from them. MATERIAL AND METHODS: Qualitative content analysis of COVID-19 vaccination-related questions from the COVID Ψ online survey of nâ¯= 85 psychiatrists and neurologists in Germany. RESULTS: In the survey, people with schizophrenia, severe lack of drive, low socioeconomic status and homelessness were seen as risk groups for non-vaccination. Increased and targeted information, education, addressing and motivation and easily accessible vaccination offers by general practitioners, psychiatrists, and neurologists as well as complementary institutions were considered as important interventions. DISCUSSION: COVID-19 vaccinations as well as information, motivation and access support should be systematically offered by as many institutions of the psychiatric, psychotherapeutic and complementary care systems in Germany as possible.

Objectives: To explore effectiveness and sustainability of guideline adherence and antibiotic consumption after establishing treatment guidelines and initiating antimicrobial stewardship (AMS) ward rounds in a university hospital emergency department (ED). Methods: Data were gathered retrospectively from 2017 to 2021 in the LMU University Hospital in Munich, Germany. Four time periods were compared: P1 (pre-intervention period); P2 (distribution of guideline pocket cards); P3 (reassessment after 3â years); and P4 (refresher of guideline pocket cards and additional daily AMS ward rounds for different medical disciplines). Primary outcome was adherence to guideline pocket cards for community-acquired pneumonia, cystitis, pyelonephritis and COVID-19-associated bacterial pneumonia. Secondary outcomes were reduction in antibiotic consumption and adherence to AMS specialist recommendations. Results: The study included 1324 patients. Guideline adherence increased in P2 for each of the infectious diseases entities. After 3â years (P3), guideline adherence decreased again, but was mostly on a higher level than in P1. AMS ward rounds resulted in an additional increase in guideline adherence (P1/P2: 47% versus 58.6%, Pâ=â0.005; P2/P3: 58.6% versus 57.3%, Pâ=â0.750; P3/P4: 57.3% versus 72.5%, Pâ<â0.001). Adherence increased significantly, not only during workdays but also on weekends/nightshifts. Adherence to AMS specialist recommendations was excellent (91.3%). We observed an increase in use of narrow-spectrum antibiotics and a decrease in the application of fluoroquinolones and cephalosporins. Conclusions: Establishing treatment guidelines in the ED is effective. However, positive effects can be diminished over time. Daily AMS ward rounds are useful, not only to restore but to further increase guideline adherence significantly.
RESUMEN
BACKGROUND & AIMS: Inhibitory receptors such as programmed death 1 (PD-1) and cytotoxic T lymphocyte-associated antigen (CTLA)-4 mediate CD8+ T-cell exhaustion during chronic viral infection, but little is known about roles in dysfunction of CD4+ T cells. METHODS: We investigated the functions of inhibitory molecules on hepatitis C virus (HCV)-, influenza-, and Epstein-Barr virus (EBV)-specific CD4+ T cells in patients with chronic infections compared with patients with resolved HCV infection and healthy donors. Expression of PD-1, CTLA-4, CD305, and CD200R were analyzed on HCV-specific CD4+ T cells, isolated from peripheral blood using major histocompatibility complex class II tetramers. We investigated the effects of in vitro inhibition of various inhibitory pathways on proliferation and cytokine production by CD4+ T cells, and we compared these effects with those from inhibition of interleukin (IL)-10 and transforming growth factor (TGF)-ß1. RESULTS: PD-1 and CTLA-4 were up-regulated on virus-specific CD4+ T cells from patients with chronic HCV infections. PD-1 expression was lower on influenza- than on HCV-specific CD4+ T cells from subjects with chronic HCV infection, whereas CTLA-4 was expressed at similar levels, independent of their specificity. CD305 and CD200R were up-regulated in HCV resolvers. Blockade of PD-L1/2, IL-10, and TGF-ß1 increased expansion of CD4+ T cells in patients with chronic HCV, whereas inhibition of IL-10 and TGF-ß1 was most effective in restoring HCV-specific production of interferon gamma, IL-2, and tumor necrosis factor α. CONCLUSIONS: We characterized expression of inhibitory molecules on HCV-, influenza-, and EBV-specific CD4+ T cells and the effects of in vitro blockade on CD4+ T-cell expansion and cytokine production. Inhibition of PD-1, IL-10, and TGF-ß1 is most efficient in restoration of HCV-specific CD4+ T cells.

BACKGROUND: Anthracyclines are agents with a wellknown cardiotoxicity. The study sought to evaluate the hemodynamic response to an anthracycline using realtime continuous-wave (CW)-Doppler ultrasound cardiac output monitoring (USCOM) and echocardiography in combination with serum biomarkers. METHODS: 50 patients (26 male, 24 female, median age 59 years) suffering from various types of cancer received an anthracycline-based regimen. Patients' responses were measured at different time points (T0 prior to infusion, T1 6 h post infusion, T2 after 1 day, T3 after 7 days, and T4 after 3 months) with CW-Doppler ultrasound (T0-T4) and echocardiography (T1, T4) for hemodynamic parameters such as stroke volume (SV; SVUSCOM ml) and ejection fraction (EF; EFechocardiography%) and with NT-pro-BNP and hs-Troponin T (T0-T4). RESULTS: During the 3-month observation period, the relative decrease in the EF determined by echocardiography was -2.1% (âµT0-T4, T0 71 ± 7.8%, T4 69.5 ± 7%, p = 0.04), whereas the decrease in SV observed using CW-Doppler was -6.5% (âµT0-T4, T0 54 ± 19.2 ml, T4 50.5 ± 20.6 ml, p = 0.14). The kinetics for serum biomarkers were inversely correlated. CONCLUSIONS: Combining real-time CW-Doppler USCOM and serum biomarkers is feasible for monitoring the immediate and chronic hemodynamic changes during an anthracycline-based regimen; the results obtained were comparable to those from echocardiography.

BACKGROUND: The admission of patients with malignancies to an intensive care unit (ICU) still remains a matter of substantial controversy. The identification of factors that potentially influence the patient outcome can help ICU professionals make appropriate decisions. PATIENTS AND METHODS: 90 adult patients with hematological malignancy (leukemia 47.8%, high-grade lymphoma 50%) admitted to the ICU were analyzed retrospectively in this single-center study considering numerous variables with regard to their influence on ICU and day-100 mortality. RESULTS: The median simplified acute physiology score (SAPS) II at ICU admission was 55 (ICU survivors 47 vs. 60.5 for non-survivors). The overall ICU mortality rate was 45.6%. With multivariate regression analysis, patients admitted with sepsis and acute respiratory failure had a significantly increased ICU mortality (sepsis odds ratio (OR) 9.12, 95% confidence interval (CI) 1.1- 99.7, p = 0.04; respiratory failure OR 13.72, 95% CI 1.39-136.15, p = 0.025). Additional factors associated with an increased mortality were: high doses of catecholamines (ICU: OR 7.37, p = 0.005; day 100: hazard ratio (HR) 2.96, p < 0.0001), renal replacement therapy (day 100: HR 1.93, p = 0.026), and high SAPS II (ICU: HR 1.05, p = 0.038; day 100: HR 1.2, p = 0.027). CONCLUSION: The decision for or against ICU admission of patients with hematological diseases should become increasingly independent of the underlying malignant disease.

BACKGROUND: Aggressive mechanical ventilation can markedly and unpredictably affect cardiac function. The fall in cardiac output (CO) is due to a reduction in left ventricular stroke volume (SV). The aim of the present pilot study was to assess the effects of different positive end-expiratory pressure (PEEP) levels on circulatory function and to compare them with continuous wave (CW)-Doppler ultrasound cardiac output monitoring (USCOM) and a thermodilution-based haemodynamic monitoring system (PiCCO). METHODS: Twenty mechanically ventilated (PEEP < or = 10 mbar) adult patients (female n = 6, male n = 14, mean age 62 years, mean SAPS II-score 48.5), the majority with pneumonia and septic shock) were followed with USCOM and PiCCO at stepwise increased PEEP-levels from 0-10 mbar (1 mbar steps). The changes in CO/SV were recorded. RESULTS: With both methods, an increase of PEEP resulted in a decrease of SV and CO. Although the absolute decrease was consistently higher by USCOM, the changes of the parameters were qualitatively comparable. CO fell from 8.83 L/min (+/- 2.39) by 0.4 L/min to 8.49 L/min (+/- 2.48) with PiCCO and from 9.3 L/min (+/- 3.43) by 1.0 L/min to 8.3 L/min (+/- 3.2) with USCOM. The median CO/SV fell by 4.5%/5.2% with PiCCO and 10.8%/9% with USCOM, respectively. Correlation of CO values with the two methods by Bland-Altman yielded comparable results (mean percentage error at PEEP 0 mbar 13%, PEEP 10 mbar 18%). An adequate flow signal with USCOM was achieved in all patients. CONCLUSIONS: A significant influence of mechanical ventilation with PEEP on haemodynamic parameters was evident both with USCOM and PiCCO. While thermodilution methods like PiCCO are well established but time-consuming and invasive, CW-Doppler based USCOM constitutes an important tool for easy, rapid and reliable diagnosis and haemodynamic monitoring of critically ill patients.

BACKGROUND: the organisation of a COVID-19 vaccination campaign for healthcare workers (HCWs) within a university hospital presents a challenge of a particularly large scale and urgency. Here, we evaluate the in-hospital vaccination process and centre for HCWs at LMU University Hospital in Munich, Germany. METHODS: We executed a mixed-method process evaluation of the vaccination centre at LMU University Hospital during the first COVID-19 vaccination campaign. In a programme monitoring, we continuously assessed the implementation of the centre's operational management including personnel resources. In evaluating the outreach to and satisfaction of the target group with the centre and process, we executed two anonymous surveys aimed at the HCWs vaccinated at the in-hospital centre (1) as well as centre staff members (2). RESULTS: staff numbers and process time per person were reduced several times during the first vaccination campaign. Lessons concerning appointment scheduling were learned. HCWs vaccinated at the in-hospital centre were satisfied with the process. A longer waiting time between admission and inoculation, perceived dissatisfying accessibility as well as an increased frequency of observed adverse events were linked to a reduced satisfaction. Comparatively subpar willingness to adhere to non-pharmaceutical measures was observed. Centre staff reported high satisfaction and a workload relatively equal to that of their regular jobs. Our outcomes provide references for the implementation of an in-hospital vaccination centre in similar settings.

Considering the role of healthcare workers (HCW) in promoting vaccine uptake and previously recorded hesitancy among HCW, we aim to examine the COVID-19 vaccination intent and status of HCW through a cross-sectional anonymous online survey at LMU University Hospital in Munich. Data collection was informed by the Health Belief Model (HBM) and focused on vaccination intent, status and on potential factors affecting the decision-making process. In total, 2555 employees completed the questionnaire. Our data showed that an approving attitude towards recommended vaccines and having received an influenza vaccine in the previous winter were strongly associated with COVID-19 vaccination intent. Further, a positive COVID-19 vaccination status was associated with a higher likelihood of approving the extension of the validity of non-pharmaceutical interventions at the workplace. Our HBM-analysis demonstrated strong associations between the perceived benefits and barriers and COVID-19 vaccination intent. Unchanged or low perceived susceptibility and severity were associated with refusal or indecisiveness. Our findings highlight the factors associated with the decision regarding a COVID-19 vaccine and indicate a pattern-like behavior in the acceptance of novel vaccines by HCW. These insights can help inform the communication aims of vaccination campaigns among HCW within similar organizational contexts or in future outbreaks.
RESUMEN
OBJECTIVES: Early patient disposition is crucial to prevent crowding in emergency departments (EDs). Our study aimed to characterise the need of in-house resources for patients treated in the ED according to the Emergency Severity Index (ESI) and the presenting complaint at the timepoint of triage. DESIGN: A retrospective single-centre study was conducted. SETTING: Data of all patients who presented to the interdisciplinary ED of a tertiary care hospital in Munich, Germany, from 2014 to 2017 were analysed. PARTICIPANTS: n=113 694 patients were included. MEASURES: ESI Score, medical speciality according to the chief complaint, mode of arrival, admission rates and discharge destination from the ED were evaluated. RESULTS: Patient disposition varied according to ESI scores in combination with the chief complaint. Patients with low ESI scores were more likely to be admitted after treatment in the ED than patients with high ESI scores. Highly prioritised patients (ESI 1) mainly required admission to an intensive care unit (ICU, 27%), intermediate care unit (IMC, 37%) or immediate intervention (11%). In this critical patient group, 30% of patients with neurological or medical symptoms required immediate intensive care, whereas only 17% of patients with surgical problems were admitted to an ICU. A significant number of patients (particularly with neurological or medical problems) required hospital (and in some cases even ICU or IMC) admission despite high ESI scores. CONCLUSIONS: Overall, ESI seems to be a useful tool to anticipate the need for specialised in-hospital resources on arrival. Patients with symptoms pointing at neurological or medical problems need particular attention as ESI may fail to sufficiently predict the care facility level for this patient group.

Recent epidemiological studies suggest that chemotherapy for metastatic breast cancer (MBC) has not contributed to a marked improvement in the patient outcome during the last decades. Randomized trials that investigated the efficacy of a first-line schedule for MBC, observed a median survival of 18-24 months. This study aimed to analyze patients with MBC who have been treated in a single university outpatient clinic for survival. Patients with MBC who had received their complete anticancer treatment in our outpatient clinic between 2000 and 2005 were analyzed for treatment schedules and survival. A total of 232 patients [median age, 53 years; range, 27-87 years; estrogen receptor and/or progesterone-positive hormone receptor, n=174 (75%); human epidermal growth factor receptor 2 overexpression (human epidermal growth factor receptor 2 positive), n=79 (34%)] were included in this analysis, of which 43.7% of hormone receptor-positive patients received 1-2, 28.3% received 3-4, and 1.7% received more than four hormonal regimens. In addition, 53.4% of all patients received up to three chemotherapeutic agents in palliative intent, whereas four to six regimens were applied in 22.1, and 12.9% received more than six subsequent regimens. An increased number of regimens were associated with an improvement in survival. The median overall survival was 44 months (95% confidence interval: 39-49). HR positivity, bone only, or single-site metastases were associated with an improved survival. An improved survival was also shown in patients who underwent locoregional procedures for oligometastatic disease (n=31; median overall survival >50 months), whereas triple-negative breast cancer was related to worse outcome (16 months; 95% confidence interval: 7-25). These data collected from a selective patient population of a single center support the hypothesis that the sequential use of all treatment modalities for MBC to its full potential may result in an increased survival. Whether innovative medicine, a step-by-step escalation of all treatment modalities according to standard guidelines and individualized clinical requirements, and a multidisciplinary treatment approach contribute to these good outcomes is debatable.

BACKGROUND & AIMS: Down-regulation of hepatitis C virus (HCV)-specific CD4(+) T-cell responses is a hallmark of chronic viral persistence in acute hepatitis C. FOXP3(+)CD25(+)CD4(+) regulatory T cells can modulate HCV-specific immune responses in vitro, but the role of virus-specific regulatory T cells in the pathogenesis of chronic viral persistence is unknown. METHODS: Two novel HLA-DR15 tetramers were synthesized to study the kinetics and phenotype of FOXP3(+)-expressing HCV-specific CD4(+) T cells from 10 patients with acute hepatitis C and 15 patients with chronic hepatitis C. RESULTS: In acute hepatitis C, generally only a low percentage of HCV-specific CD4(+) T cells expressed FOXP3(+) (mean of 2.5% in patients with self-limited acute hepatitis C vs 2.4% in patients with evolving chronic hepatitis C). Although distinct but short-lived increases in virus-specific FOXP3(+)CD4(+) T cells occurred in 3 patients (30%, 26%, and 7% of tet(+) CD4(+) T cells, respectively), these did not correlate with the evolution of chronic hepatitis C. HCV-specific FOXP3(+)CD4(+) T cells displayed a distinct phenotype, with only 10% expressing CD25 and 40% being CD127low. Interestingly, this phenotype of FOXP3(+)CD4(+) T cells was already expanded in bulk CD4(+) T cells in patients with chronic hepatitis C. CONCLUSIONS: Although short-lived increases in HCV-specific FOXP3(+)CD4(+) T cells occur during the course of acute hepatitis C, we could not demonstrate an association of HCV-specific regulatory T cells and persistent viremia.

BACKGROUND: Adults with congenital heart disease and ventricular dysfunction are prone to liver congestion, leading to fibrosis or cirrhosis but little is known about the prevalence of liver disease in atrial switch patients. Liver impairment may develop due to increased systemic venous pressures. This prospective study aimed to assess non-invasively hepatic abnormalities in adults who underwent Senning or Mustard procedures. METHODS: Hepatic involvement was assessed non-invasively clinically by laboratory analysis, hepatic fibrotic markers, sonography, and liver stiffness measurements [transient elastography (TE) and acoustic radiation force impulse imaging (ARFI)]. RESULTS: Overall, 24 adults who had undergone atrial switch operation (13 Senning, 11 Mustard; four female; median age 27.8 years; range 24-45 years) were enrolled. In liver stiffness measurements, only three patients had values within the normal reference. All other patients showed mild, moderate or severe liver fibrosis or cirrhosis, respectively. Using imaging and laboratory analysis, 71% of the subjects had signs of liver fibrosis (46%) or cirrhosis (25%). CONCLUSIONS: Non-invasive screening for liver congestion, fibrosis or cirrhosis could be meaningful in targeted screening for hepatic impairment in patients with TGA-ASO. As expert knowledge is essential, patients should be regularly controlled in highly specialised centres with cooperations between congenital cardiologists and hepatologists.
RESUMEN
Cryoglobulinaemia may cause cutaneous vasculitis and glomerulonephritis, potentially leading to end stage renal failure. An important proportion of cryoglobulinaemias are secondary to hepatitis C virus infection. Emerging antiviral treatment options offer a chance for causal therapy of these cases of cryoglobulinaemia. This review summarises the classification and clinical and therapeutic aspects of cryoglobulinaemic vasculitis and glomerulonephritis.

BACKGROUND: Eisenmenger syndrome as a severe form of cyanotic congenital heart disease results in a complex multisystemic disorder. Due to increased systemic venous pressure and the inability to ensure systemic perfusion and metabolic requirements, the liver may develop congestion, fibrosis or cirrhosis. This study aimed to assess hepatic abnormalities in Eisenmenger patients non-invasively. METHODS AND RESULTS: 10 adults with Eisenmenger syndrome (six female; median age 44.2years; range 23-62years) were enrolled and hepatic involvement was assessed - using clinical assessment, laboratory analysis, hepatic fibrotic markers, abdominal sonography and liver stiffness measurements (transient elastography (TE) and acoustic radiation force impulse imaging (ARFI)). Using imaging and laboratory analysis, 60% (6/10) of the Eisenmenger patients had signs of liver fibrosis (5/10) or cirrhosis (1/10). While TE, however, showed no relevant liver abnormalities in any Eisenmenger patient, ARFI detected liver fibrosis in 5/10 and cirrhosis and 1/10 patients. CONCLUSIONS: Adult Eisenmenger patients are at increased risk of hepatic impairment. Non-invasive screening could be helpful in detecting liver alterations. In our small series, however, TE could not detect fibrosis or cirrhosis in any affected patient, while ARFI was very reliable. Patients should be transferred to centres, where a multidisciplinary expert knowledge is available and a close collaboration between cardiologists and hepatologists exists.

BACKGROUND: There is evidence that frequency of AIN/AC rises in HIV+ individuals treated with HAART whilst frequency of most other opportunistic neoplasms declines with immune reconstitution. METHOD: 1472 patients were screened 3655 times for ACA as a strong risk factor for AIN/AC. The periods 1985 to 1995 (before introduction of PI in Germany) and 1996 to 2001 were compared. In addition, 10 cases of AC are described. Time between HIV-infection and AC as well as time between ACA and AC is assessed, pre-treatment with HAART, age, CD4-cell count and CDC-stage at timepoint of diagnosis of AC is mentioned. RESULTS: There are significantly higher numbers of ACA+ screens in the years after 1996 (p<0.001) independent of number of CD4+ T-lymphocytes. AIN/AC occurs more often in HIV+ individuals, preferably in advanced disease stages, at younger age and within a shorter time after first signs of ACA than in HIV-negative population. AC occurs more likely in patients pretreated with HAART, AC tumor stage is ACIS in most cases. - CONCLUSION: Analogical to AIN/AC, frequency of ACA seems to rise under HAART (regimen including PI) although risk for opportunistic diseases usually decreases under HAART. Similarity of AC to ICC in HIV+ women is striking and AC could become part of the list of AIDS-indicator diseases. According to pre-existing cost-effectiveness calculations [6], screening for AC (including physical examination, proctoscopy, cytology and biopsy of all suspect lesions) should be performed every 2-3 years in patients with CD4+ T-lymphocytes >500/microl and yearly in patients with CD4+ T-lymphocytes <500/microl. Existing ACA should be treated thoroughly. The role of serum HIV load in development and progression of ACA [20], and in consequence of AIN/AC needs further investigation.

BACKGROUND: Anthracyclines are agents with a well known documented anti-tumoral activity. Cardiac side effects are the principal toxicity. Here we evaluate and monitor the onset of late anthracycline-induced cardiotoxicity with real-time CW-Doppler ultrasound cardiac output monitoring (USCOM®) and echocardiography in combination with serum biomarkers. METHODS: Fifty-two patients without cardiac disease who had received an anthracycline-based regimen for various cancer types were included in this study. Patients' hemodynamic parameters as stroke volume (SV USCOM (mL)) and ejection fraction (EF ECHOCARDIOGRAPHY (%)) were measured with USCOM and echocardiography and correlated to serum biomarkers (NT-pro-BNP and cTnT). RESULTS: Eighteen patients (34.6%) developed cardiac disease (NYHA I-III). An increasing cumulative anthracycline dose was associated with a decrease of the EF determined by echocardiography as well the SV by USCOM and with a higher NYHA class. Those patients who experienced cardiac disease showed a reduction of the EF and SV and increased serum biomarkers. CONCLUSIONS: Real-time CW-Doppler USCOM, is a fast and reliable method to monitor late hemodynamic changes as a symptom of anthracycline-induced cardiotoxicity comparable to the findings by echocardiography and serum biomarkers.
RESUMEN
OBJECTIVES: Gender differences between donors and recipients might have an effect on outcome after heart transplantation. Literature and registries reveal controversial results. We reviewed 1000 heart transplantations at our center focusing on the influence of gender differences on short- and long-term outcome after heart transplantation. MATERIALS AND METHODS: We performed a retrospective analysis of 1000 (960 primary and 40 redo-heart transplantations) between August 1981 and July 2008. In contrast to other studies, the data for gender differences (donor gender and recipient gender) were evaluated for recipient survival and survival conditional to early mortality. RESULTS: Female donors are significantly older than male donors (females, 36.5 ± 14.5 years; males, 31.2 ± 13.8 years). One-year survival was significantly inferior in male recipients receiving female donor hearts (mR/fD: 73.7%) compared to females receiving male donor organs (fR/mD: 90.9%) (P = .045). Univariate analysis revealed that, for recipients who survived > 1 year, survival at 10 years was significantly greater for female donors and female recipients (90%) than it was for male donors and male recipients (72%; P = .034). Multivariate analysis showed that the gender combination with female donors and female recipients was an independent indicator for greater long-term survival (P = .04). CONCLUSIONS: The gender combination of female donors and male recipients had a greater risk for early mortality after heart transplantation, and the combination of male donors and female recipients resulted in favorable short-term outcomes. In long-term follow-up, recipients of hearts from female donors had better survival, especially female recipients.

USCOM is an ultrasound-based method which has been accepted for noninvasive hemodynamic monitoring in various clinical conditions (USCOM, Ultrasonic cardiac output monitoring). The present study aimed at comparing the accuracy of the USCOM device with that of the thermodilution technique in patients with septicemia. We conducted a prospective observational study in a medical but noncardiological ICU of a university hospital. Septic adult patients (median age 55 years, median SAPS-II-Score 43 points) on mechanical ventilation and catecholamine support were monitored with USCOM and PiCCO (n = 70). Seventy paired left-sided CO measurements (transaortic access = CO(US-A)) were obtained. The mean CO(US-A) were 6.55 l/min (±2.19) versus CO(PiCCO) 6.5 l/min (±2.18). The correlation coefficient was r = 0.89. Comparison by Bland-Altman analysis revealed a bias of -0.36 l/min (±0.99 l/min) leading to a mean percentage error of 29%. USCOM is a feasible and rapid method to evaluate CO in septic patients. USCOM does reliably represent CO values as compared to the reference technique based on thermodilution (PiCCO). It seems to be appropriate in situations where CO measurements are most pertinent to patient management.
RESUMEN
BACKGROUND: The angiographic incidence of coronary dilatation (CD) in the nontransplant population is approximately 0.2% to 5%. The endothelial-dependent and -independent causes for CD are postulated. So far, the incidence and prognosis of CD after heart transplantation is unknown. METHODS: We retrospectively analyzed the annual coronary angiographies of 688 heart transplant recipients regarding the incidence of CD (defined as ≥1.5-fold localized increased vessel diameter or diffuse dilatation involving more than 50% of the coronary artery). A subgroup analysis of coronary epicardial (quantitative angiography) and microvascular (doppler flow measurement) vasomotor function in response to acetylcholine (endothelial dependent) and adenosine (endothelial independent) as well as intravascular ultrasound was performed in 177 patients. RESULTS: CD was detectable in 26 patients (3.8%) and was associated with stenosing coronary artery disease in 27% of the patients. Segments with CD tended to have less intimal hyperplasia compared with nondilated segments. A diffuse dilatation (type I-II) was present in 63% of the recipients. The right coronary artery was always involved. The patients with CD (5 of 177) showed a 31% reduced flow velocity in the dilated coronaries compared with the nondilated coronary arteries (P=0.03). Microvascular endothelial-independent function was impaired in CD by -29% (coronary flow reserve mean 1.9 vs. 2.7; P=0.04), whereas endothelial-dependent response was unchanged. Epicardial endothelial-dependent and -independent responses were not different between the groups. Incidence of CD was not associated with limited survival. CONCLUSION: The incidence of CD in the nontransplant population is similar to that in the transplanted population. However, the latter shows a more diffuse extent. Heart transplantation patients with CD had microvascular endothelial-independent functional limitations and flow deceleration, whereas survival was not affected.
