UTI in children-management
UTIs are one of the most common bacterial infections of childhood In ambulatory care about 6 % of all acutely ill children have UTI’s Data has shown that about 8 % of all girls and 2 % of all boys will have atleast one episode by 7 yrs of age and about 12 % to 30 % of those will experience a recurrence Short female urethra and male circumcision account for marked female preponderance beyond infancy Bimodal peaks are seen with the first one in infancy and other peak from 2-4 yrs
Most common causes for UTI are bacteria ○ viruses , fungi and parasites can occasionally also be responsible ○ Adenoviruses can be associated with haemorrhagic cystitis ○ Candida can cause UTIs in immunocompromised children Escherichia coli ( E.coli ) is the most common uropathogen accounting for about 80 % to 90 % of paediatric UTI’s Other members of the Enterobacteriaceae family – Klebsiella , Proteus , Citrobacter , Serratia and Enterobacter can also be responsible Pathogenesis of UTI is complex -several host and pathogen factors influence the course of the illness and its outcome E Coli- Special properties as fimbriae which attach to the uroepithelial cell surface allows them to overcome host defenses
Lower UTI infection of bladder (cystitis ) or urethra – bacteriuria with no systemic features localised symptoms as lower abdominal or suprapubic pain , dysuria , urinary frequency and urgency
Upper UTI -infection and inflammation of the kidneys ( pyelonephritis ) and ureters accompanied by systemic features such as anorexia , vomiting , lethargy and malaise children with bacteriuria and fever ≥ 38 deg or temp < 38 but with loin pain / tenderness should be considered to have acute pyelonephritis / upper UTI.
In younger patients differentiating between upper and lower UTI is not always possible as typical symptoms are often absent.
Infants with a high risk of serious illness – refer PAU Infants < 3 months with possible UTI-refer PAU Infants and children 3 months or older with acute pyelonephritis / upper UTI ○ consider referral to a paediatric specialist ○ treat with antibiotic as per NICE guidance 3 months or older with cystitis / lower UTI-treat as per NICE guidance.
