[Guidelines for the management of hyperglycaemia in hospitalised adult patients]. / Smjernice za zbrinjavanje hiperglikemije u odraslih hospitaliziranih bolesnika.

INTRODUCTION: The aim was to prepare guidelines for the management of in-hospital hyperglycaemia in adult patients in intensive care units and regular wards. CONTRIBUTORS: Working group led by two coordinators consists of repre- sentatives of professional societies within the Croatian Medical Association. EVIDENCE: These guidelines are derived from the guidelines of international professional societies. Level of evidence and strength of recommendation are evaluated according to GRADE (Grading of Recommendations, Assessment, Development and Evaluation) system. Decision making process: Working group produced Guidelines draft by a consensus. The draft has been delivered to professional societies for review. Final document is accepted by all included societies. CONCLUSION: Hyperglycaemia is a frequent, serious and demanding complication in hospitalized patients. Results of published studies suggest that its regulation decreases morbidity and mortality. Implementation of locally developed standardized protocols promoting basal-bolus insulin regimen is regarded as the most important measure for management of hyperglycaemia in hospital. Present guidelines are a set of practical, rational and feasible recommendations and suggestions.

Sepsis syndrome in Croatian intensive care units: piloting a national comparative clinical database.

AIM: To assess the incidence of sepsis in selected intensive care units (ICUs) in Croatia, isolates from blood cultures, and sepsis outcomes, and to compare the results with those from other European countries. METHODS: In the pilot phase of the national comparative clinical database project, we included 24 ICUs--general, specialized, neonatal, pediatric, and adult--18 from university hospitals, 3 from county hospitals, and 4 from city hospitals. By retrospective chart review, trained data collectors abstracted the data on the case mix, management strategies, and outcomes in patients consecutively admitted to ICUs. Central validation for incomplete, illogical, or inconsistent values is regularly performed to improve accurateness. RESULTS: Of 5293 patients treated in 24 ICUs from November 1, 2004, to October 31, 2005, 456 (8.6%) were treated for sepsis syndrome or severe sepsis. The most common isolates from positive blood cultures were Esherichia coli (11.6%), Pseudomonas species (9.9%), and methicillin-resistant Staphylococcus aureus (9.3%). With the mean Acute Physiology and Chronic Health Evaluation (APACHE) II score of 10.0 and Sequential Organ Failure Assessment (SOFA) score of 2.4, the overall mortality for sepsis syndrome, severe sepsis, and septic shock was 29%, 35%, and 34%, respectively. When compared to university hospitals and county hospitals, city hospitals with the smallest gravitating population had significantly lower APACHE II and SOFA scores, but significantly higher mortality. CONCLUSIONS: Overall mortality of patients with sepsis syndrome in Croatian ICUs was high, but outcomes of their treatment were comparable with those in other European countries. Better education in triage and treatment strategies is needed, including better implementation of Surviving Sepsis Campaign guidelines.

Familial acquired thrombotic thrombocytopenic purpura: ADAMTS13 inhibitory autoantibodies in identical twins.

Thrombotic thrombocytopenic purpura (TTP) either occurs in a congenital form caused by ADAMTS13 gene mutations or it is acquired and most often due to ADAMTS13 inhibitory autoantibodies. In congenital TTP siblings are often affected, while acquired TTP occurs sporadically and familial clustering has not been described so far. We report identical twin sisters suffering from acquired TTP due to immunoglobulin G (IgG) autoantibodies inactivating ADAMTS13, suggesting an important role of hitherto unidentified genetic determinants of ADAMTS13 inhibitor formation. These cases also demonstrate that familial clustering is not sufficient for unambiguously diagnosing hereditary ADAMTS13 deficiency and congenital TTP.

[Thrombotic thrombocytopenic purpura and hemorrhagic fever with renal syndrome: possible dilemma in differential diagnosis]. / Tromboticka trombocitopenicka purpura i hemoragijska vrucica s bubreznim sindromom: moguca diferencijalno-dijagnosticka dilema.

UNLABELLED: Thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS) are classical diseases characterized by thrombocytopenia and microangiopathic hemolytic anemia. Microangiopathic hemolytic anemia is also a part of clinical picture in patients with hemorrhagic fever with renal syndrome (HFRS). Some overlap in other elements of clinical picture between TTP and HFRS is possible, which could pose difficulties in differential diagnosis. Early treatment of patients with TTP is essential and significantly improves the outcome, whereas the treatment of HFRS is mainly supportive. In the last ten years, we treated 13 patients with TTP and 17 patients with HFRS. Two patients with HFRS were initially treated as TTP because it was not possible to exclude TTP on the basis of clinical picture. Further clinical course and serologic tests excluded TTP and suggested HFRS. CONCLUSION: Sometimes it is difficult to distinguish HFRS from TTP because thrombocytopenia and microangiopathic hemolytic anemia are present in both diseases and overlaps in other parts of clinical picture are possible. The serious consequences of delay in the efficacious treatment of patients with TTP could also influence the physicians' decisions.
