Summary Aims To investigate the clinical benefit of routine procalcitonin (PCT) measurement in the medical intensive care unit (ICU) of a tertiary referral hospital. Methods Adult patients with suspected infections were included. White blood cells, C‑reactive protein (CRP), and PCT were measured. Results In this study 129 patients of median age 64 years (interquartile range 39–89 years) were prospectively included. The Acute Physiology And Chronic Health Evaluation II (APACHE II) and Sequential Organ Failure Assessment (SOFA) scores were 21 ± 14 and 7 ± 6, respectively. Intensive care unit (ICU) mortality was 22.5%. Immunocompromised patients constituted 39.5%. A significant correlation was observed between PCT and APACHE II (Spearman’s rho 0.461, p

The present study aimed to examine the impact of vancomycin, teicoplanin and linezolid on the development of acute kidney injury (AKI) in critically ill patients with normal renal function at the intensive care unit (ICU) admission. The primary endpoint of our research was to ascertain whether a significant difference exists among the use of the investigated antibiotics and the incidence of AKI in critically ill patients with severe infection. Secondary endpoints were to analyze the efficacy of vancomycin, teicoplanin and linezolid. These were defined by the duration of antibiotic use, ICU length of stay, hospital length of stay and patient outcome.

Floating thrombi in the aorta are very rare and usually associated with coagulation disorder. We report a patient with longstanding, relatively good controlled myeloproliferative neoplasm (MPN) who developed floating thrombi in the thoracic aorta while taking dabigatran etexilate for thromboprophylaxis of atrial fibrillation (AF). Treatment with low molecular weight heparin was successful as patient recovered completely and control CTA showed complete resolution of the thrombi. To our knowledge, this is the first case of aortic thrombi that occurred despite dabigatran use. This raises concern that DOACs might not be efficient therapy for patients with myeloproliferative neoplasms. Another question is whether patients with polycythemia vera should continue the use of acetylsalicylic acid when anticoagulant drug is needed.

Aim: To explore the protective role of hydration, urine alkalization (Na bicarbonate) and high doses of antioxidant (N-acetylcysteine) in the prevention of CIN. Material and methods: In a prospective, randomized, single-blinded study patients were divided into three groups: 1) peroral hydration, 2) Na bicarbonate infusion and 3) N-acetylcysteine (NAC) plus NaHCO3 infusion. Serum creatinine (SCr), blood urea nitrogen (BUN), and neutrophil gelatinase-associated lipocalin (NGAL) were measured before and 48 hours after the angiography. Mehran score was calculated for each patient. Results: The study included 106 patients. Groups were comparable regarding the baseline characteristics. According to Mehran risk score 70 % of patients had a low risk, 24% medium and 6% high risk score for development of CIN. After the procedure renal function was preserved in all patients (SCr 103(87.0-121.5), BUN 5.8 (4.9-7.6), creatinine clearance 74.7(55.3-97.6), NGAL 11.4(5.4-19.9)) regardless of the Mehran risk score. The follow up was completed for 73 patients (68 %). Twenty two patients (32 %) developed chronic kidney disease, mostly classified as G3a and G3b according to KDIGO guidelines. Chronic kidney disease developed in patients with the positive history of diabetes and in patients who had higher Mehran score before the diagnostic procedure. Conclusion: The study showed that patients with preserved renal function are not prone to CIN. Regardless of the protocol used, no case of CIN was observed. Our results indicate that adequate hydration is a key component in maintaining the renal function. Higher Mehran score might be useful in predicting the development of chronic kidney disease., Cilj: Ispitati protektivnu ulogu hidracije, alkalizacije mokraće (natrijevim bikarbonatom) i visokih doza antioksidansa (N-acetilcistein) u prevenciji kontrastne nefropatije. Materijali i metode: U prospektivnom istraživanju pacijenti su bili podijeljeni u tri skupine: 1) peroralna hidracija, 2) infuzija natrijevog bikarbonata i 3) infuzija N-acetilcisteina (NAC) i NaHCO3. Serumska vrijednost kreatinina, ureje i neutrophil gelatinase-associated lipocalin (NGAL) izmjerene su prije i 48 sati nakon angiografije. Svakom pacijentu izračunati su Mehran bodovi koji predstavljaju rizik razvoja kontrastne nefropatije. Rezultati: U istraživanje je uključeno 106 pacijenata. Sve tri skupine pacijenata imale su usporedive osnovne karakteristike. Prema bodovima po Mehranu, 70 % pacijenata imalo je niski rizik, 24 % srednji i 6 % visoki rizik razvoja kontrastne nefropatije. Nakon kontrastne pretrage bubrežna funkcija bila je očuvana u svih pacijenata (serumski kreatinin 103 (87.0 – 121.5), urea 5.8 (4.9 – 7.6), klirens kreatinina 74.7 (55.3 – 97.6), NGAL 11.4 (5.4 – 19.9)) neovisno o riziku procijenjenom bodovima po Mehranu. Praćenje je završeno za 73 pacijenta (68 %). Dvadeset i dva pacijenta (32 %) razvila su kroničnu bubrežnu insuficijenciju, klasificiranu prema KDIGO smjernicama kao G3a i G3b. Kronična bubrežna insuficijencija razvila se u pacijenata sa šećernom bolesti i u pacijenata koji su imali viši broj bodova prema Mehranu prije dijagnostičke pretrage. Zaključak: Istraživanje je pokazalo da pacijenti s normalnom bubrežnom funkcijom imaju mali rizik razvoja kontrastne nefropatije. U ispitivanoj skupini pacijenata nije zabilježen niti jedan slučaj kontrastne nefropatije bez obzira na vrstu protokola koji je korišten za hidraciju. Naši rezultati ukazuju na to da je adekvatna hidracija ključna u prevenciji kontrastne nefropatije. Nadalje, postoji mogućnost da viši broj bodova po Mehranu može poslužiti kao prediktor razvoja kronične bubrežne bolesti.

Cilj: Vankomicin je antibiotik koji se koristi za liječenje infekcija uzrokovanih Gram- -pozitivnim bakterijama, no kod nekih pacijenata uzrokuje ozljedu bubrega. Budući da standardni biomarkeri ozljede bubrega ne pokazuju dovoljnu osjetljivost i specifičnost, potrebno je pronaći nove biomarkere kako bismo mogli ranije detektirati poremećaje bubrežne funkcije te pravovremenim prekidom ili promjenom terapije spriječiti daljnje ozljede bubrega. Cilj je rada bio usporediti proteomske profile urina dviju pacijentica oboljelih od upale pluća koje su primale terapiju vankomicinom sa i bez kliničkih znakova ozljede bubrega uzrokovanih navedenim antibiotikom, kako bismo identificirali nove potencijalne proteinske biomarkere akutne ozljede bubrega uzrokovanog vankomicinom. Prikaz slučaja: Uzorci urina prikupljeni su treći i sedmi dan terapije vankomicinom od pacijentice sa i pacijentice bez kliničkih znakova bubrežne disfunkcije te su analizirani dvodimenzionalnom gel elektroforezom kombiniranom s MALDI-TOF/TOF masenom spektrometrijom. Vidljive razlike u proteomskim profilima urina između dviju pacijentica javljaju se treći, a naročito su izražene sedmi dan terapije. Dvodimenzionalna gel elektroforeza kombinirana s masenom spektrometrijom potvrdila je već ranije dokazanu ulogu proteina neutrofilnog lipokalina povezanog s gelatinazom (NGAL, engl. neutrophil gelatinase-associated lipocalin) kao biomarkera akutne ozljede bubrega, te otkrila ekspresiju citoskeletnog keratina 1 tipa II i retinol-vezujućeg proteina 4 (RBP4, engl. retinol-binding protein 4) samo u urinu pacijentice kod koje je terapija vankomicinom uzrokovala poremećaj bubrežne funkcije. Zaključci: Citoskeletni keratin 1 tipa II i retinol-vezujući protein 4 mogli bi predstavljati nove potencijalne biomarkere ozljede bubrega uzrokovane vankomicinom. Potrebne su daljnje studije na većem broju pacijenata kako bi se validirali dobiveni rezultati i utvrdio njihov potencijalni dijagnostički i klinički značaj., Aim: Vancomycin is an antibiotic used to treat infections caused by Gram-positive bacteria which can induce renal injury in some patients. Since standard biomarkers of kidney injury lack sufficient sensitivity and specificity, there is an unmet need for novel biomarkers that would enable early detection of renal injury and timely cessation or modification of treatment to prevent more severe kidney injury. The goal of this paper was to compare proteomics profiles of urine samples collected from two vancomycin-treated patients suffering from pneumonia with and without clinical symptoms of drug-induced renal dysfunction as to identify novel potential protein biomarkers of vancomycin-induced kidney injury. Case report: Urine samples were collected on the third and seventh day of vancomycin therapy from patients with and without clinical signs of acute kidney injury. Samples were analysed by two-dimensional gel electrophoresis and MALDI-TOF/TOF mass spectrometry. Differences in urinary proteomes between these two patients could be observed on the third and especially on the seventh day of therapy. Two-dimensional gel electrophoresis combined with mass spectrometry confirmed previously established role of neutrophil gelatinase-associated lipocalin (NGAL) as biomarker of renal injury, and revealed the expression of keratin 1 type II cytoskeletal and retinol-binding protein 4 (RBP4) only in urine from the patient with vancomycin- induced renal dysfunction. Conclusions: Keratin 1 type II cytoskeletal and retinol-binding protein 4 could be considered novel potential biomarkers of vancomycin-induced kidney injury. Additional studies with larger patient cohorts are needed to validate these findings and investigate their potential diagnostic and clinical significance.

Mucinous cystadenoma is a rare benign neoplasm and is usually discovered incidentally. Pleuritis and pericarditis, inflammation of the pleura and pericardium, may represent manifestations of autoimmune disorders especially in female subjects. We report a patient with polyserositis that was resolved after removal of the mucinous cystadenoma. To the best of our knowledge, this is a first report describing pleuritis and pericarditis as an initial presentation of mucinous cystadenoma of an appendix. A forty-year-old Caucasian female patient with a history of pleuritis and recurrent pericarditis was admitted to the hospital due to acute abdomen. At that time she was taking indomethacin and colchicine due to pericarditis that was controlled only with the combination of these two drugs. The patient had elevated erythrocyte sedimentation rate (ESR), increased C-reactive protein (CRP) and normocytic anemia. Immunological tests, including antinuclear antibody, anti-neutrophil cytoplasmic antibody, rheumatoid factor, and anti-cyclic citrullinated peptide antibodies, were repeatedly negative. Emergency surgery revealed acute appendicitis with perforation and subsequent diffuse peritonitis. Histopathological examination showed acute appendicitis and mucinous cystadenoma. Following the surgery the patient did not take any drugs. Fourteen months later the patient was symptom free. Pleuritis and pericarditis in female patients are most often associated with autoimmune diseases. We assume that increased ESR and CRP with anemia detected in the patient may reflect the altered immunity that is due to mucinous cystadenoma. We believe that this report has a broader clinical impact, implying that benign tumor could alter immunity, which can lead to unusual presentation such as polyserositis.

At the University Hospital Centre Zagreb, 37 patients underwent liver transplanta-tion in the period from 2010 to 2014. Six patients had fatal complications in the ear-ly post-transplantation period and deceas-es in the surgical intensive care unit (ICU). All other patients (31) were transferred to the medical ICU and later to the medical ward. The most common indications for liver transplantation were alcoholic liver disease (9 patients) and hepatitis C (8 pa-tients). Two-thirds of the patients were male (67.7%) with an average age of 51 years. Thirty patients were discharged alive from the hospital. Infections developed in nine patients, mostly pneumonia and peritonitis. Only one patient experienced infection caused by multi-drug resistant bacteria, namely peritonitis due to me-thicillin-resistant Staphylococcus aureus (MRSA). All infections were successfully treated with antibiotics and none of them caused graft rejection.

Introduction Critical illness is commonly complicated by hyperglycaemia caused by mediators of stress and inflammation. Severity of disease is the main risk factor for development of hyperglycaemia, but not all severely ill develop hyperglycemia and some do even in mild disease. We hypothesised that acute disease only exposes a latent disturbance of glucose metabolism which puts those patients at higher risk for developing diabetes. Methods Medical patients with no history of impaired glucose metabolism or other endocrine disorder admitted to an intensive care unit between July 1998 and June 2004 were considered for inclusion. Glucose was measured at least two times a day, and patients were divided into the hyperglycaemia group (glucose ≥7.8 mmol/l) and normoglycaemia group. An oral glucose tolerance test was performed within six weeks after discharge to disclose patients with unknown diabetes or pre- diabetes who were excluded. Patients treated with corticosteroids and those terminally ill were also excluded from the follow-up which lasted for a minimum of five years with annual oral glucose tolerance tests. Results A five-year follow-up was completed for 398 patients in the normoglycaemia group, of which 14 (3.5%) developed type 2 diabetes. In the hyperglycaemia group 193 patients finished follow- up and 33 (17.1%) developed type 2 diabetes. The relative risk for type 2 diabetes during five years after the acute illness was 5.6 (95% confidence interval (CI) 3.1 to 10.2). Conclusions Patients with hyperglycaemia during acute illness who are not diagnosed with diabetes before or during hospitalization should be considered a population at increased risk for developing diabetes. They should, therefore, be followed-up, in order to be timely diagnosed and treated.

Diabetes mellitus (DM) is a highly prevalent disease: about one-quarter of patients admitted to hospital is diagnosed with DM, but there are also a large number of patients who are undiagnosed. An acutely ill patient with hyperglycaemia and no history of diabetes may have stress hyperglycaemia or a first manifestation of diabetes, but it is virtually impossible to establish diagnosis based on measurements of glucose. HbA1c is widely used as a marker of glycaemic control and has been proposed and used, but not yet officially accepted, as a diagnostic marker for diabetes. We have tested its usefulness for diagnosing diabetes in the intensive care setting.
