The aim of this study was to find the source of
in the intensive care unit (ICU) after an outbreak during the coronavirus disease 2019 (COVID-19) pandemic, as there was no
detected on usually ...screened susceptible surfaces. The screening of the ICU environment was done in April 2021 when eleven different samples were taken. One
isolate was recovered from the air conditioner and was compared with four clinical
isolates obtained from patients hospitalized in January 2021. Isolates were confirmed by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), minimum inhibitory concentrations (MICs) were determined, and the multilocus sequence typing (MLST) was performed. The molecular identification of
isolates as ST208, the presence of the same
carbapenemase gene, and the same antibiotic susceptibility profile suggest that the isolate recovered from the air conditioner is the same as the isolates recovered from hospitalized patients. The environmental isolate was recovered three months later than the clinical isolates, emphasizing the ability of
to survive on dry abiotic surfaces. The air conditioner in the clinical environment is an important but undoubtedly neglected source of
outbreaks, hence, frequent disinfection of hospital air conditioners with appropriate disinfectants is mandatory to mitigate the circulation of
between patients and the hospital environment.
Nonalcoholic fatty liver disease (NAFLD) is a term describing excessive accumulation of fat in hepatocytes, and is associated with metabolic syndrome and insulin resistance. NAFLD prevalence is on ...increase and goes in parallel with the increasing prevalence of metabolic syndrome and its components. That is why Croatian guidelines have been developed, which cover the screening protocol for patients with NAFLD risk factors, and the recommended diagnostic work-up and treatment of NAFLD patients. NAFLD screening should be done in patients with type 2 diabetes mellitus, or persons with two or more risk factors as part of metabolic screening, and is carried out by noninvasive laboratory and imaging methods used to detect fibrosis. Patient work-up should exclude the existence of other causes of liver injury and determine the stage of fibrosis as the most important factor in disease prognosis. Patients with initial stages of fibrosis continue to be monitored at the primary healthcare level with the management of metabolic risk factors, dietary measures, and increased physical activity. Patients with advanced fibrosis should be referred to a gastroenterologist/hepatologist for further treatment, monitoring, and detection and management of complications.
Aim To analyze an additional set of "Y-chromosome genetic markers to acquire a more detailed insight into the diversity of the Croatian population. Methods A total of 518 Yfiler Plus profiles were ...genotyped. Allele frequencies, haplotype frequencies, and haplotype diversity were calculated by using the STRAF software v. 2.0.4. Genetic distances were quantified by R.sub.st with AMOVA online tool from the YHRD. The evolutionary history was inferred with the neighbor-joining method of phylogenetic tree construction in the MEGAX software. Whit Athey's Haplogroup Predictor v. 5 was used for additional comparison with regional and other European populations. Results A total of 507 haplotypes were used for genetic STR analysis. An interpopulation study on 17 Y-STR markers showed the lowest genetic diversity between the Croatian and Bosnian-Herzegovinian populations and the highest between the Croatian and Irish populations. Additional interpopulation comparison with the original 27 Y-STR markers (for the population with available data) was also performed. A total of 518 haplotypes were used in the determination of haplogroup diversity. Haplogroup I with its sublineage I2a expressed the highest prevalence. The second most prevalent haplogroup was R, with its major sublineage R1a, except for the subpopulation of Hvar, where E1b1b was the second most prevalent haplogroup. Rare haplogroups also confirmed in this study were L, T, and Q. G1 was detected for the first time in the Croatian population. Conclusion We obtained a new insight into the differences between examined subpopulations of Croatia and their possible (dis)similarities with neighboring and distant populations.

Nealkoholna bolest masne jetre (engl. nonalcoholic fatty liver disease, NAFLD) oznacava prekomjerno nakupljanje masti unutar hepatocita, a povezana je s metabolickim sindromom i inzulinskom ...rezistencijom. Ucestalost NAFLD-a je u porastu i prati rastucu ucestalost metabolickog sindroma i njegovih komponenata. Stoga su izradene hrvatske smjernice koje obuhvacaju postupnik probira bolesnika s rizicnim cimbenicima za NAFLD te preporucenu dijagnosticku obradu i lijecenje bolesnika s NAFLD-om. Probir na NAFLD potrebno je raditi bolesnicima s dijabetesom tipa 2 ili osobama s dva ili vise rizicnih cimbenika u sklopu metabolickog sindroma, a probir se izvodi neinvazivnim laboratorijskim i slikovnim metodama za otkrivanje fibroze. Obradom bolesnika potrebno je iskljuciti postojanje drugih uzroka ostecenja jetre te utvrditi stadij fibroze kao najvaznijeg cimbenika u prognozi bolesti. Bolesnici s pocetnim stadijima fibroze nastavljaju se pratiti na razini primarne zdravstvene zastite uz lijecenje metabolickih rizicnih cimbenika, dijetetske mjere i pojacanu tjelesnu aktivnost. Bolesnike sa znacajnom fibrozom preporuca se uputiti gastroenterologu/hepatologu radi daljnjeg lijecenja, pracenja te prepoznavanja i zbrinjavanja komplikacija bolesti.

Wilson disease (WD) is an autosomal recessive disorder of copper metabolism, characterized by its accumulation in tissues which results in hepatic, neurological, and/or psychiatric symptoms. The aim ...of this study was to investigate the genetics of WD in Croatian patients.
Correlation of the clinical presentation subtype and the age at onset of the diagnosis of WD with the ATP7B genotype was investigated in a group of Croatian WD patients. DNA from peripheral blood samples was tested for the p.His1069Gln by direct mutational analysis and other polymorphisms were identified by sequence analysis of coding and flanking intronic regions of ATP7B gene.
In the group of 75 WD patients of Croatian origin, 18 different mutations in ATP7B gene were detected, three of which were novel. The p.His1069Gln mutation was most frequent, being detected in 44 Croatian WD patients (58.7%). Most ATP7B mutations (90.4%) were located in exons 5, 8, 13, 14, and 15.
Clinical diagnosis of WD was confirmed in 59 patients by detecting mutations on both ATP7B alleles. The age at onset of WD and the type of WD clinical presentation showed no significant correlation with the ATP7B genotype.
Transplantation is a definitive treatment option for patients with end‐stage liver disease, and for some patients with acute liver failure, hepatocellular carcinoma or end‐stage renal disease. ...Long‐term post‐transplantation complications have become an important medical issue, and cardiovascular diseases (CVD) are now the leading cause of mortality in liver or kidney transplant recipients. The increased prevalence of metabolic syndrome (MS) likely plays a role in the high incidence of post‐transplantation CVD. MS and its hepatic manifestation, non‐alcoholic fatty liver disease (NAFLD), are prevalent among the general population and in pre‐ and post‐transplantation settings. MS components are associated with recurrent or de novo NAFLD in transplant recipients, potentially influencing post‐transplantation survival. Moreover, recent data reveal an important association between NAFLD and risk of incident of chronic kidney disease (CKD). Therefore, NAFLD identification could represent an additional clinical feature for improving the stratification of liver and kidney transplant recipients with regards to risks of CVD, CKD and renal allograft dysfunction. All MS components are potentially modifiable; therefore, it is crucial that hepatologists, nephrologists and primary care physicians become more engaged in managing post‐transplantation metabolic complications. The present review discusses the recent clinical evidence regarding the importance of MS and its components after liver and kidney transplantation, as well as the link between MS and NAFLD after liver and kidney transplantation.
Purpose
Data on the seroprevalence of hepatitis E virus (HEV) in heamodialysis (HD) patients are conflicting, ranging from 0 to 44%. The aim of this study was to determine the HEV seroprevalence and ...risk factors among HD patients in Croatia.
Methods
A total of 394 HD patients from six medical facilities in five Croatian cities (three sites in the continental and three sites in the coastal region) were tested for HEV IgM/IgG antibodies using an enzyme-linked immunosorbent assay. Additionally, all samples were tested for HEV RNA by RT-PCR. Sociodemographic data and risk factors were collected using a questionnaire.
Results
HEV IgG antibodies were detected in 110 (27.9%) patients. The seroprevalence varied significantly between dialysis centres, ranging from 5.2 to 43.4% (
p
= 0.001). HEV IgM antibodies were found in 0.04% of IgG positive patients. All patients tested negative for HEV RNA. Factors associated with HEV IgG seropositivity were age > 60 years (OR 8.17; 95% CI 1.08–62.14), living in the continental parts of the country (OR 2.58; 95% CI 1.55–4.30), and transfusion of blood products (OR 1.66; 95% CI 1.01–2.73). After adjusting for age and gender, patients from continental regions had higher odds of HEV seropositivity compared to patients from coastal regions (OR 2.88; 95% CI 1.71–4.85) and those who had RBC transfusions (OR 1.70, 95% CI 1.02–2.69) compared to those who did not.
Conclusion
The study showed a high HEV seropositivity among HD patients in Croatia, with significant variations between geographical regions. Continental area of residence and RBC transfusion were the most significant risk factors for HEV seropositivity. Due to the high seroprevalence, routine HEV screening among HD patients, especially in transplant candidates should be considered.
Infection with non-1 genotype in Croatia is detected in 41.2% of patients with chronic hepatitis C. Since the last treatment guidelines for hepatitis C patients, little has been changed. With today's ...standard of care, sustained viral response can be achieved in 43% to 85% of non-1 CHC patients, which is not satisfactory at all. The lowest cure rate is usually found among patients with genotype 3 and 4 infection. The grouping of genotype 2 and genotype 3 patients to "easy to treat" genotypes was an unfortunate consequence of their underrepresentation in previous large registration clinical trials. Careful re-examination of the data obtained shows clearly enough that patients with genotype 3 infection respond less to treatment than genotype 2 patients. They sometimes behave more like patients with genotype 1 infection. Small progress is found in treatment approach and viral kinetics might be a useful tool for tailoring therapy to improve efficacy. Rapid virologic response is the best parameter to predict success of therapy. For patients who achieve a rapid viral response, consideration of shortened therapy (< 24 weeks) may be reasonable although sustained viral response is still slightly higher with 24 weeks of therapy. Nevertheless, the presence of poor prognostic factors (high viral load, advanced fibrosis, obesity, increased age, insulin resistance and liver non-viral steatosis) may discourage a shortened course of therapy. Extending therapy (> 24 weeks) in patients who do not achieve a rapid viral response would be beneficial, particularly in patients with genotype 3 infection and poor prognostic factors, but formal recommendation should be confirmed in prospective trails. New data suggest a prognostic role for IL28B polymorphisms mostly in genotype 3 patients not achieving a rapid viral response and these could also be considered for improved tailoring of therapy. In conclusion, new treatments are urgently needed for non-1 genotype chronic hepatitis C patients. So far, telaprevir and boceprevir have failed to show a satisfactory activity in these genotypes. Evaluation of many promising molecules such as second generation of protease inhibitors or NS5B nucleos(t)ide inhibitors, NS5A inhibitors, cyclophilin inhibitors or their combinations with or without pegylated interferon or ribavirin is still in progress.
