Sažetak
Background: Group B Streptococcus (GBS) is a significant cause of invasive disease among adult non-pregnant patients with increasing incidence and mortality rates. Although non-alcoholic fatty liver disease (NAFLD) is associated with components of metabolic syndrome previously recognized as risk factors for GBS, the impact of NAFLD on GBS course and outcomes is unknown. Methods: We conducted a retrospective cohort study of all non-pregnant adult patients diagnosed with invasive GBS infection during a 15-year period. Results: 102 patients were included in the study (46.1% males ; median age 69, IQR 58-78 years). Disease primarily presented as bacteremia without a defined source (37 ; 36.3%), cellulitis/erysipelas (35 ; 34.3%), pneumonia (13 ; 12.7%) and endocarditis (8 ; 7.8%). The most common comorbidities were diabetes (42 ; 41.2%), dyslipidemia (39 ; 38.2%), cardiovascular disease (34 ; 33.3%), peripheral vascular disease (21 ; 20.6%), obesity (21 ; 20.6%) and malignancy (10 ; 9.8%). Based upon the results of abdominal ultrasound, the patients were divided into two groups: the ones with steatosis (44 ; 43.1%) and the ones without steatosis (58 ; 56.9%). There were no significant differences in clinical presentations and comorbidities between groups. In-hospital mortality was 29.5% (13/44) in patients with NAFLD and 10.3% (6/58) in the control group (p=0.0200). Endocarditis (OR 6.69 ; 95%CI 1.045- 44.46, p=0.0410), acute renal failure (OR 13.92 ; 95%CI 3.00-77.71, p=0.0013), qSOFA > 2 (OR 23.93 ; 95%CI 4.66-171.2) and NAFLD (OR 6.64 ; 95%CI 1.23-47.88, p=0.0258) were independently associated with in-hospital mortality. Conclusions: NAFLD is associated with higher mortality in patients suffering from invasive GBS disease which appears to be independent of other components of the metabolic syndrome, such as obesity and diabetes mellitus. Uvod: Streptokok grupe B (GBS) značajan je uzrok invazivne bolesti kod odraslih bolesnika s porastom incidencije i smrtnosti. Iako je nealkoholna masna bolest jetre – NAFLD (engl. non-alcoholic fatty liver disease) povezana s komponentama metaboličkog sindroma koji su prepoznati kao čimbenici rizika za GBS, utjecaj NAFLD na tijek i ishode invazivne GBS bolesti još uvijek nije poznat. Metode: Proveli smo retrospektivno kohortno istraživanje svih odraslih bolesnika koji nisu trudni, a kojima je dijagnosticirana invazivna GBS infekcija tijekom 15-godišnjeg razdoblja. Rezultati: U istraživanje je uključeno 102 bolesnika (46, 1% muškaraca ; srednja dob 69, IQR 58-78 godina). Bolest se primarno prezentirala kao bakterijemija nepoznatog ishodišta (37 ; 36, 3%), celulitis/erizipel (35 ; 34, 3%), pneumonija (13 ; 12, 7%) i endokarditis (8 ; 7, 8%). Najčešći komorbiditeti bili su dijabetes (42 ; 41, 2%), dislipidemija (39 ; 38, 2%), kardiovaskularne bolesti (34 ; 33, 3%), periferne vaskularne bolesti (21 ; 20, 6%), pretilost (21 ; 20, 6%) i maligna bolest (10 ; 9, 8%). Prema nalazu ultrazvuka abdomena, bolesnici su podijeljeni u dvije skupine: bolesnici s NAFLD (44 ; 43, 1%) i bolesnici bez steatoze jetre (58 ; 56, 9%). Nije bilo značajnih razlika u kliničkoj prezentaciji i komorbiditetima među skupinama. Smrtnost za vrijeme hospitalizacije iznosila je 29, 5% (13/44) kod bolesnika s NAFLD i 10, 3% (6/58) u kontrolnoj skupini (p = 0, 0200). Endokarditis (OR 6, 69 ; 95% CI 1, 045- 44, 46, p = 0, 0410), akutno zatajenje bubrega (OR 13, 92 ; 95% CI 3, 00-77, 71, p = 0, 0013), qSOFA> 2 (OR 23, 93 ; 95% CI 4, 66-171, 2) i NAFLD (OR 6, 64 ; 95% CI 1, 23- 47, 88, p = 0, 0258) bili su neovisno povezani sa smrtnošću. Zaključci: NAFLD je povezan s većom smrtnošću kod bolesnika s invazivnom GBS bolešću i čini se da je to neovisno o drugim komponentama metaboličkog sindroma, kao što su pretilost i dijabetes melitus.
