vod: Dijabetička ketoacidoza (DKA) jedna je od najozbiljnijih akutnih komplikacija šećerne bolesti (ŠB). Pojedina istraživanja su pokazala da su infekcije precipitirajući čimbenik u polovice ispitanika. Nekoliko novijih istraživanja naglašava da je loše pridržavanje liječenja također česti uzrok DKA. Cilj: Identifi cirati najčešće precipitirajuće čimbenike za DKA u Republici Hrvatskoj. Ispitanici i postupci: Ovo retrospektivno multicentrično istraživanje uključivalo je bolesnike sa ŠB-om tipa 1 ili tipa 2 s dijagnozom DKA između 1. siječnja 2014. i 31. prosinca 2018. i liječenih u 5 različitih središta za liječenje ŠB-a: Dubrovnik, Našice, Split, Zagreb i Osijek. U analizu je uključena samo prve epizoda DKA. Pacijenti koji boluju od steroidnog ŠB-a i ŠB-a zbog endokrinih poremećaja kao što su akromegalija i Cushingov sindrom bili su isključeni. Rezultati: Istraživanjem je obuhvaćeno 160 bolesnika (55 % muškaraca), od kojih je 68% imalo ŠB tip 1. Srednja dob ispitanika bila je 42 godine (od 18 do 89). Najčešći uzrok DKA bila je infekcija (57 %), zatim slabo kontrolirani ŠB (37 %) i prva prezentacija ŠB-a (9 %), dok je u 7% bolesnika DKA bila uzrokovana ostalim uzrocima kao što su kvar inzulinske pumpe, moždani ili srčani udar. U skupini bolesnika s infekcijama najčešće su bile infekcije mokraćnog sustava (30 %), probavne infekcije (30 %) i infekcije respiratornog trakta (19 %), dok je 21 % bolesnika imalo druge izvore infekcije. U 36 ovih bolesnika uz infekciju je bio prisutan i prethodno loše kontroliran ŠB, a u 12 % DKA uzrokovana infekcijom bila je prvo očitovanje bolesti. U bolesnika sa ŠB-om tipa 2 infekcije su češće bile uzrok DKA nego u bolesnika sa ŠB-om tipa 1 (P < 0,05). U bolesnika sa ŠB-om tipa 1, slabo regulirana glikemija je češće uzrok DKA (31%) nego u bolesnika sa ŠB-om tipa 2 (18 %). Zaključak: Najčešći precipitirajući čimbenici za razvoj DKA su infekcije i loša regulacija ŠB-a. Potrebna je bolja edukacija bolesnika o važnosti redovite primjene inzulina i korekcije terapije tijekom akutne bolesti.Introduction: Diabetic ketoacidosis (DKA) is one of the most serious acute complications of diabetes mellitus (DM). In some studies, infections have been found to be a precipitating factor in more than half of the subjects. On the other hand, several recent studies emphasize that poor treatment adherence is also a common cause of DKA. Objective: To identify the most common precipitating factors for DKA in Croatia. Patients and Methods: This retrospective, multicenter study included DM type 1 or DM type 2 patients diagnosed with DKA between January 1, 2014 and December 31, 2018, and treated in 5 different DM treatment centers, i.e., Dubrovnik, Našice, Split, Zagreb and Osijek. Only the fi rst episode of DKA was included in the analysis. Patients receiving steroids and DM due to endocrine disorders such as acromegaly and Cushing\u27s syndrome were excluded. Results: The study included 160 patients (55% of men), of whom 68% had DM type 1. The mean age of the respondents was 42 (18-89) years. The most common cause of DKA was infection (57%), followed by poorly controlled DM (37%) and fi rst presentation of DM (9%), while in 7% of patients DKA was due to other causes such as insulin pump failure, stroke or myocardial infarction. In the group of patients with infections, urinary tract infections (30%), gastrointestinal infections (30%) and respiratory tract infections (19%) were most common, whereas 21% of patients had other sources of infection. In 36% of these patients, the infection was associated with previously poorly controlled diabetes, and in 12% of them, DKA caused by the infection was the fi rst manifestation of the disease. In patients with type 2DM, infections were more often the cause of DKA than in patients with type 1DM (p<0.05).Poorly controlled glycemia appeared to be a more frequent cause of DKA in patients with type 1 DM (31%) than in patients with type 2 DM (18%). Conclusion: The most common precipitating factors for the development of DKA were infections and poor diabetes management. Better education of patients about the importance of regular insulin administration and correction of therapy in acute illness could reduce the risk of DKA
