简要总结
Evaluate the prevalence and types of urinary tract infections, the features of the gut and urinary tract microbiota in cirrhosis, to assess its importance in the development of complications and outcomes of cirrhosis.
详细描述
Asymptomatic bacteriuria in an individual without urinary tract symptoms is defined by a mid-stream sample of urine showing bacterial growth > 105 cfu/mL in two consecutive samples in women and in one single sample in men. A complicated urinary tract infections occurs in an individual in whom factors related to the host (e.g. underlying diabetes or immunosuppression) or specific anatomical or functional abnormalities related to the urinary tract. Laboratory urine culture is the recommended method to determine the presence or absence of clinically significant bacteriuria.
Catheter-associated urinary tract infections refers to urinary tract infections occurring in a person whose urinary tract is currently catheterised or has been catheterised within the past 48 hours. Signs and systemic symptoms compatible with сatheter-associated urinary tract infections include new onset or worsening of fever, rigors, altered mental status, malaise, or lethargy with no other identified cause, flank pain, costovertebral angle tenderness, acute haematuria, pelvic discomfort and in those whose catheters have been removed dysuria, urgent or frequent urination and suprapubic pain or tenderness. Microbiologically, сatheter-associated urinary tract infections is defined by microbial growth of > 103 cfu/mL of one or more bacterial species in a single catheter urine specimen or in a mid-stream voided urine specimen from a patient whose urethral, suprapubic, or condom catheter has been removed within the previous 48 hours.

结局指标
主要结局
Number of Participants with variceal bleeding
时间窗: from the date of assignment until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 3 months
The main diagnostic method of variceal bleeding is endoscopy
Number of Participants with hepatorenal syndrome
时间窗: from the date of assignment until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 3 months
Type-1 hepatorenal syndrome is characterized by a rapid deterioration of renal function with a doubling of serum creatinine to values above 2.5 mg/dl within 2 weeks, type-2 hepatorenal syndrome is characterized by a slower increase in serum creatinine to values above 1.5 mg/dl. The main clinical characteristic of Type-1 hepatorenal syndrome is acute renal failure, while the main characteristic of type-2 hepatorenal syndrome is refractory ascites.
Number of Participants with hepatic coma
时间窗: from the date of assignment until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 3 months
hepatic encephalopathy is graded with the West Haven Criteria: Grade 0 - No obvious changes other than a potentially mild decrease in intellectual ability and coordination Grade 1 - Trivial lack of awareness; euphoria or anxiety; shortened attention span; impaired performance of addition or subtraction Grade 2 - Lethargy or apathy; minimal disorientation for time or place; subtle personality change; inappropriate behaviour Grade 3 - Somnolence to semistupor, but responsive to verbal stimuli; confusion; gross disorientation Grade 4 - Coma
