RESUMO

Background: Acinetobacter baumannii is a clinically significant pathogen with a high incidence of multidrug resistance that is associated with life-threatening nosocomial infections. Here, we aimed to provide an insight into the clinical characteristics and outcomes of a unique group of A. baumannii infections in which the isolates were resistant to carbapenems and most other antibiotic groups in a tertiary-care intensive care unit (ICU). Methods: We performed a retrospective observational study in which records of patients hospitalized in the ICU between June 1, 2021 and June 1, 2023 were reviewed. We checked the clinical, laboratory, and microbiological records of all adult patients who had carbapenem-resistant A. baumannii (CRAB) infections. Prior antibiotic treatments and definitive antibiotic treatments after culture positivity and susceptibility test results were recorded. C-reactive protein (CRP) and procalcitonin levels and leukocyte counts were noted. Length of ICU stay and 30-day mortality were defined as the outcome parameters. Results: During the study period, 57 patients were diagnosed with CRAB infections. The respiratory tract was the leading infection site (80.7%). In non-survivors, bloodstream infections (21.9% vs. 4.0% P=0.05) and colistin-resistant (col-R) CRAB infections (43.8% vs. 24.0%, P=0.12) were more common than in survivors, but these parameters were not statistically significant. The length of ICU stay was not different between survivors and non-survivors. Overall, the rate of col-R among CRAB clinical isolates was 35.1%. The 30-day mortality in all patients with CRAB infection was 56.1%. Mortality in col-R CRAB and colistin-susceptible (col-S) CRAB infections was 70.0% and 48.6%, respectively (P=0.12). Prior carbapenem use was 56.1%. Prior colistin use before col-R and col-S CRAB infections was not significant (35.0% vs. 27.0%, P=0.53). Conclusions: Our study provides real-world data on highly resistant A. baumannii infections and shares the characteristics of infections with such resistant strains. Unfortunately, carbapenem resistance in A. baumannii is a challenge for intensive care specialists who are faced with few treatment options, and colistin resistance further complicates the problem.

RESUMO

BACKGROUND: Refeeding syndrome is characterized by metabolic and electrolyte alterations that result from the initiation of feeding after a period of inadequate caloric intake. Especially, in the elderly with acute and/or chronic illness, nutritional deficiencies are common, and diminished oral intake with effects of catabolic status yields malnutrition. This study was conducted to evaluate refeeding hypophosphatemia and its consequences on outcomes in the oldest old critically ill patients. METHODS: This study was designed as a retrospective cohort study that included patients who were 80 years old or older admitted to ICU. Patients were grouped depending on whether hypophosphatemia occurred after 48 hours of admission who started feeding. RESULTS: The median age of all patients was 87[82-90] years and 61(73%) of them were female. Refeeding hypophosphatemia was observed in 25(30%) patients. When patients were grouped depending on the occurrence of hypophosphatemia, groups were similar according to the severity scores, and comorbidities. Neither ICU mortality nor hospital mortality was different between groups (p=0.76 and p=0.19, respectively). CONCLUSION: Refeeding hypophosphatemia incidence was similar to previous studies, although study patients were the highest risk group. Outcome parameters including mortality rate and length of ICU stay were not different between patients with or without refeeding hypophosphatemia.

RESUMO

Introduction: We aimed to evaluate ventilator-associated pneumonia (VAP) incidence rate, risk factors, and isolated microorganisms in COVID-19 patients as the primary endpoint. Evaluation of VAP-associated intensive care unit (ICU) and hospital mortalities was the secondary endpoint. Materials and Methods: Records of patients admitted between March 2020- June 2021 to our pandemic ICU were reviewed and COVID-19 patients with VAP and non-VAP were evaluated retrospectively. Comorbidities, management, length of ICU stay, and outcomes of VAP and non-VAP patients, as well as risk factors for VAP mortality, were identified. Result: During the study period, 254 patients were admitted to the ICU. After the exclusion, the data of 208 patients were reviewed. In total, 121 patients required invasive mechanical ventilation, with 78 (64.5%) developing VAP. Length of ICU and hospital stays were longer in VAP patients (p<0.01 and p<0.01 respectively). Steroid use was higher in VAP patients, although it was not statistically significant (p= 0.06). APACHE II score (p<0.01) was higher in non-VAP patients. ICU mortality was high in both groups (VAP 70%, non-VAP 77%). VAP mortality was higher in males (p= 0.03) and in patients who required renal replacement therapy (p= 0.01). Length of ICU stay (p= 0.04), and length of hospital stay (p<0.01) were both high in VAP survivors. The most common isolated microorganisms were Acinetobacter spp. and Klebsiella spp. in VAP patients and most of them were extensively drug-resistant. Conclusions: Critically ill COVID-19 patients who required invasive mechanical ventilation developed VAP frequently. The length of ICU stay was longer in patients who developed VAP and ICU mortality was high in both VAP and non-VAP patients. The length of hospital and ICU stays among VAP survivors were also considerably high which is probably related to the long recovery period of COVID-19. The most frequently isolated microorganisms were Acinetobacter spp. and Klebsiella spp. in VAP patients.

RESUMO

Objective: We aimed to detect the risk factors for invasive candida infections by evaluating the fungal strains cultivated from samples taken in a medical intensive care unit (ICU). Materials and Methods: We investigated fungal growths between January 1, 2016, and December 1, 2018, retrospectively. All reported fungal growths and demographic characteristics, clinical features, treatments and outcomes of the patients with fungal growths were recorded. Results: Fungal growths were reported from 384 different samples obtained from 179 ICU patients. The most common strain was determined to be C. albicans (47.9%).The incidence of non-albicansCandida strains was increased over the years (2016 - 44%, 2017 - 52.5%, 2018 - 49%), most significantly C. glabrata (7.7% to 14.6%). The most common strain was C. parapsilosis (57.9%) in patients with candidemia, and infection was more severe among them. Fluconazole resistance was rare. When patients with and without fungal growth were compared, a significant difference was found between groups in terms of age, acute physiology and chronic health evaluation II (APACHE II) score, length of ICU and hospital stay, ICU and hospital mortality (p<0.001, p =0.011, p<0.001, p=0.031, p =0.016). Candida score was significantly higher in candidemic patients (3.0 vs 0.0 p<0.001). Conclusion: Among fungal growths in samples from critically ill patients, the incidence of non-albicans Candida strains was gradually increasing. Older age, higher APACHE II score, and longer hospital and ICU stay were associated with fungal growths.

RESUMO

BACKGROUND: There are limited data on the long-term outcomes of COVID-19 from different parts of the world. AIMS: To determine risk factors of 90-day mortality in critically ill patients in Turkish intensive care units (ICUs), with respiratory failure. STUDY DESIGN: Retrospective, observational cohort. METHODS: Patients with laboratory-confirmed COVID-19 and who had been followed up in the ICUs with respiratory failure for more than 24 hours were included in the study. Their demographics, clinical characteristics, laboratory variables, treatment protocols, and survival data were recorded. RESULTS: A total of 421 patients were included. The median age was 67 (IQR: 57-76) years, and 251 patients (59.6%) were men. The 90-day mortality rate was 55.1%. The factors independently associated with 90-day mortality were invasive mechanical ventilation (IMV) (HR 4.09 [95% CI: [2.20-7.63], P < .001), lactate level >2 mmol/L (2.78 [1.93-4.01], P < .001), age ≥60 years (2.45 [1.48-4.06)], P < .001), cardiac arrhythmia during ICU stay (2.01 [1.27-3.20], P = .003), vasopressor treatment (1.94 [1.32-2.84], P = .001), positive fluid balance of ≥600 mL/day (1.68 [1.21-2.34], P = .002), PaO2/FiO2 ratio of ≤150 mmHg (1.66 [1.18-2.32], P = .003), and ECOG score ≥1 (1.42 [1.00-2.02], P = .050). CONCLUSION: Long-term mortality was high in critically ill patients with COVID-19 hospitalized in intensive care units in Turkey. Invasive mechanical ventilation, lactate level, age, cardiac arrhythmia, vasopressor therapy, positive fluid balance, severe hypoxemia and ECOG score were the independent risk factors for 90-day mortality.

RESUMO

COVID-19, caused by severe acute respiratory syndrome coronavirus-2, typically presents with respiratory symptoms and fever, but still a variety of clinical presentations have been reported. In this study, it was aimed to report a case of COVID-19 with an atypical presentation and an atypical course. As well, the recovery phase was complicated with GBS and consequently cytomegalovirus infection. It should be kept in mind that patients with COVID-19 severe disease need to be followed for neurological and other complications which may arise during the course of critical illness.

RESUMO

Background/aim: There is a need for a scoring system for predicting ICU prognosis of patients with ANCA-associated vasculitis (AAV), but there are limited data on it in the literature. Therefore, we aimed to determine the scores that can estimate the prognosis of patients with AAV during intensive care follow up. Materials and methods: All adult patients admitted to the medical ICUs of 4 reference university hospitals in Turkey due to AAV activation and/or disease/treatment complications in the last 10 years were included in this study. Demographic data, treatments before ICU, the Birmingham Vasculitis Activity Score (BVAS) score at the time of vasculitis diagnosis, and BVAS, APACHE II, SOFA, and SAPS II scores at the ICU admission, treatments, procedures, and complications during ICU stay were recorded for all AAV patients. Results: Thirty-four patients were included in the study. The median age of the patients was 60 (42­70) years, and 64.7% were male. Twenty-five patients were diagnosed with Granulomatosis with polyangiitis, and 9 were diagnosed with Microscopic polyangiitis. The most common ICU admission causes were hemorrhage (85.3%) and sepsis/septic shock (67.6%). Twenty patients (58.8%) died in the ICU follow up. There were significant differences in APACHE II (P = 0.004) and SAPS II (P = 0.044) scores between survivors and nonsurvivors, while there were no significant differences in BVAS (during diagnosis P = 0.089 and ICU admission P = 0.539) and SOFA (P = 0.097) scores. APACHE II score was found to be an independent risk factor for ICU mortality (OR = 1.231, CI 95% = 1.011­1.498, P = 0.038) according to logistic regression analysis. An APACHE II score of greater than 20.5 predicted ICU mortality with 80% sensitivity and 70% specificity (AUC = 0.8, P = 0.004, Likelihood ratio = 2.6) according to the ROC curve analysis. Conclusion: APACHE II score can be used for the prediction of ICU mortality in AAV patients.

RESUMO

Coronavirus disease 2019 (COVID-19) has been demonstrated to be the cause of emerging atypical pneumonia. In patients with tracheostomy, coronavirus hypothetically coexists with well-known bacterial agents. A 61-year-old male patient with tracheostomy was admitted to the hospital with dyspnea, fever and increased tracheal secretions. Laboratory findings revealed lymphopenia and elevated C-reactive protein and procalcitonin levels. Chest computed tomography showed consolidation areas and ground-glass opacities more prominent in subpleural areas. Although; two consecutive RT-PCR analyses of combined nasopharengeal/oropharengeal swabs were found to be negative for SARS-CoV-2 RNA, positivity was reported for endotracheal aspirate (ETA) sample. Significant growth of Pseudomonas aeruginosa and Stenotrophomonas maltophilia was detected in the bacterial culture of ETA sample. In conclusion, clinical samples for SARS-CoV-2 should be obtained through the lower respiratory tract, if possible and if upper airway samples are negative. To the best our knowledge, our paper is the first report of the patient with tracheostomy who was treated successfully for COVID-19.

RESUMO

BACKGROUND: In intensive care unit (ICU), although there is no standard protocol for maintenance of immunosuppressive (IS) treatments for the kidney transplant recipients (KTx), the dose and the number of IS drugs are decreased according to the center's experience. The aim of this study is to evaluate the changes in IS treatment during stays in the ICU and to evaluate the safety and results of this modification on the IS treatment in the ICU arbitrarily. METHOD: We evaluated retrospectively our kidney transplant recipients in ICU between 2012 and 2017. The immunosuppressive protocols and the results were taken from the ICU documents. RESULTS: A total of 31 (18 male, 13 female) patients were suitable for the analysis. They were all under the triple IS protocol including Tacrolimus (Tac) + Mycophenolate mofetil (MMF) + steroid before the admission. The reason for ICU admission were severe sepsis in all patients. In ICU, 16 patients (51.6%) died, and a total of 10 patients were lost with functional graft. Change in IS treatment is as follows: a total of the 23 patients (74.2%) were given only steroids, and 8 patients (25.8%) were changed from triple to 2 drugs. Acute kidney injury developed in 42% (13 patients) of the patients in ICU. CONCLUSION: In our study, we observed that life-threatening severe infections were the main cause of ICU admission in KTx. Reduction in IS treatments are common practice, and reduction to a single dose of steroid was the most frequently chosen IS treatment. Eighty percent of patients are discharged with reduction of steroid gradually. None of the patients developed acute rejection and permanent graft injury.

RESUMO

Hemophagocytic lymphohistiocytosis (HLH) is a rare and life-threatening syndrome that may be triggered by hereditary factors, autoimmune and immunologic disorders, infectious diseases, malignancies and medications. Suspicion of the disease and early treatment is of paramount importance. Since the presentation of HLH with only skin involvement is rare, early diagnosis may be difficult. A pathologically confirmed HLH case that presented with maculopapular skin lesions after certolizumab treatment is being reported in this presentation.

RESUMO

INTRODUCTION: We aimed to determine risk factors for nephrotoxicity and factors affecting mortality in patients who received colistin. METHODOLOGY: Critical patients who received colistin were enrolled. Pregnancy, age < 18 years, basal creatinine level > 2 mg/dL, colistin use for < 48 hours, and previous renal replacement therapy were exclusion criteria. KDIGO stages were determined according to creatinine levels. Patients were grouped as those with no acute kidney injury (Group N0) and those with acute kidney injury (Group N). Their demographic data, APACHE II and SOFA scores, treatments, and laboratory results were recorded. RESULTS: A total of 91 patients were included: 27 in Group N0 and 64 in Group N. Demographic data were similar between groups; however, higher admission APACHE-II scores (OR:1.179, 95% CI:1.033-1.346, p = 0.015) and need for vasopressors (OR:5.486, 95% CI:1.522-19.769, p = 0.009) were found to be independent risk factors for nephrotoxicity. Higher APACHE II scores (OR:1.253, %95 CI:1.093-1.437, p = 0.001), presence of coronary artery disease (OR:7.720, % 95 CI: 1.613-36.956, p = 0.011), need for vasopressors (OR: 4.587, % 95 CI: 1.224 - 17.241, p = 0.024), hypoalbuminemia (OR: 4.721, % 95 CI: 1.088 - 20.469, p = 0.038), and higher direct bilirubin levels (OR: 1.806, % 95 CI: 1.055 - 3.092, p = 0.031) were independent risk factors for mortality. CONCLUSION: When use of colistin is considered in ICU patients, presence of modifiable risk factors for nephrotoxicity such as hypoalbuminemia, nephrotoxic drug administration, and presence of shock should be determined and managed to prevent nephrotoxicity.

RESUMO

Crimean-Congo hemorrhagic fever (CCHF) is a tick borne viral disease which can also be transmitted by direct contact with blood or tissue specimens of infected animals or humans. We present a fatal case of CCHF, who was diagnosed after death, and describe the post-exposure management plan for the health care workers (HCWs) involved in her care. In total of 52 HCWs were involved in the patient's care and they were stratified into risk groups. Overall, 20 HCWs were grouped in high and intermediate risk groups, including the HCW with needle stick injury. High and intermediate risk groups were offered post exposure prophlaxis (PEP) with ribavirin. Fourteen of 20 HCWs started PEP, however 10 ceased after negative CCHF-PCR results. Negative CCHF-PCR results were reported for all HCWs at the 5th day of exposure. Side effects with PEP developed in 5 of HCWs and were mainly gastrointestinal complaints which reversed after drug discontinuation. All HCWs were followed for 14 days both clinically and with laboratory tests. None of the HCWs developed CCHF. PEP with ribavirin can be considered as a safe option in protection.

RESUMO

PURPOSE: This study aimed to evaluate the effects of not measuring gastric residual volume (GRV) in intensive care patients on a mechanical ventilator and receiving enteral feeding on the feeding intolerance, gastroesophageal reflux (GER) risk, and nutritional adequacy. METHODS: This randomized clinical study was performed in 2 medical intensive care units of 2 university hospitals in Ankara, Turkey. The patients were randomized into 2 groups. In the group with GRV monitoring, GRV was measured 3 times a day, and the GRV threshold was accepted as 250 mL. In addition, 24-hour pH monitoring was used in this group to assess the risk of GER. In the group without GRV monitoring, GRV was not measured. The patients were followed-up for 5 days. RESULTS: The feeding targets were reached more quickly in the group without GRV monitoring (n = 26) with no increase in the complication rate (P < .05). No significant relationship was found between GRV and GER in the group with GRV monitoring (n = 25) (P > .05). CONCLUSION: The discrepancies in GRV measurement make it unreliable for monitoring feeding intolerance and GER. The use of GRV measurements may therefore be discontinued as part of the standard care protocol in medical intensive care units.

RESUMO

BACKGROUND AND AIM: The aim of this study was to determine the actions of caffeic acid phenethyl ester (CAPE) on the changes of endothelin-1 (ET-1) level, tumor necrosis factor- (TNF-) alpha, and oxidative stress parameters such as superoxide dismutase (SOD) activities and malondialdehyde (MDA) levels in experimental sepsis model in rats. MATERIALS AND METHODS: Twenty-four rats were randomly divided into three experimental groups: sham (group 1), sepsis (group 2), and sepsis + CAPE (group 3), n = 8 each. CAPE was administered (10 µmol/kg) intraperitoneally to group 3 before sepsis induction. Serum ET-1, serum TNF-alpha, tissue SOD activity, and tissue MDA levels were measured in all groups. RESULTS: Pretreatment with CAPE decreased ET-1, TNF-alpha, and MDA levels in sepsis induced rats. Additionally SOD activities were higher in rats pretreated with CAPE after sepsis induction. CONCLUSION: Our results demonstrate that CAPE may have a beneficial effect on ET and TNF-alpha levels and oxidative stress parameters induced by sepsis in experimental rat models. Therefore treatment with CAPE can be used to avoid devastating effects of sepsis.

RESUMO

OBJECTIVE: To report a case of bupropion-associated thrombotic thrombocytopenic purpura (TTP) syndrome. CASE SUMMARY: A 55-year-old man was admitted with complaints of diarrhea, acute renal failure, and confusion ~ 54 days after bupropion initiation for smoking cessation. Subsequently he had a tonic-clonic seizure and had to be intubated because of altered consciousness. Laboratory findings were compatible with microangiopathic hemolytic anemia. He was diagnosed as TTP for which the Naranjo adverse drug reaction probability scale indicated a probable relationship with bupropion (a score of 5). He was treated with plasma exchange, systemic corticosteroids, hemodialysis and recovered fully. DISCUSSION: Bupropion is an anti-depressant drug also indicated for smoking cessation. It has widely reported neuropsychiatric and allergic adverse effects; however, TTP associated with bupropion has only been reported once. The clinical course of TTP in this case was compatible with TTP related to acute, immune mediated drug toxicity, which suggests that auto-antibodies might have been responsible. CONCLUSIONS: Given the fact that the clinical condition is compatible with acute, immune-mediated TTP syndrome, we suggest bupropion deserves evaluation for auto-antibody induction. Prescribers should be aware of the possible risk of thrombocytopenia and TTP.

RESUMO

BACKGROUND: Early enteral nutrition (EN) in patients receiving mechanical ventilation commonly has been advocated, based mainly on studies conducted in mixed populations of trauma and surgery patients. In this study, ventilator-associated pneumonia rates and outcomes were compared in mechanically ventilated medical intensive care unit (ICU) patients receiving enteral versus parenteral nutrition. METHODS: Patients fulfilling inclusion criteria between February 1, 2004, and January 31, 2006, were included. Patients were randomized to enteral or parenteral nutrition (PN) within 48 hours of intubation. Development of ventilator-associated pneumonia, assessment as to whether day feeding goal was attained, duration of mechanical ventilation, ICU and hospital length of stay (LOS), and mortality rates were recorded. RESULTS: Of 249 consecutive patients receiving mechanical ventilation, 71 patients were included. Thirty (42.3%) patients received EN, and 41 (57.7%) received PN. There was no difference between groups for age, sex, body mass index, and scores on the Acute Physiology and Chronic Health Evaluation II. Ventilator-associated pneumonia rate, ICU and hospital LOS, and mortality rates were similar for both groups. In the parenterally fed group, duration of mechanical ventilation was longer (p = .023), but the feeding goal was attained earlier (p = .012). CONCLUSIONS: In mechanically ventilated patients in the medical ICU, ventilator-associated pneumonia rates, ICU and hospital lengths of stay, and ICU and hospital mortality rates of patients receiving PN are not significantly different than those in patients receiving EN, and feeding goals can more effectively be attained by PN. Yet, duration of mechanical ventilation is slightly longer in patients receiving PN.

RESUMO

This experimental study was designed to determine effects of Nigella sativa oil (NSO) on endothelin-1 (ET-1) level and oxidative stress parameters, superoxide dismutase (SOD) and malondialdehyde (MDA) in a rat sepsis model. Twenty four adult Wistar albino rats were divided randomly into three groups: sham group (group 1), sepsis group (group 2), sepsis group pretreated with NSO (group 3). Serum ET-1, tissue SOD and tissue MDA levels were measured in all groups. Compared to group 1, ET-1 and MDA levels were higher in group 2. ET-1 and MDA levels in NSO pretreated group 3 were lower with respect to group 2 (p<0.03, and p<0.02, respectively). Additionally, SOD levels in group 3 were found to be higher than group 2 (p<0.02). Based on our results, it can be concluded that NSO may have a positive impact on ET-1 levels and oxidative stress induced by sepsis in experimental rat models.
