“…After the introduction of the H. influenzae type b vaccine, invasive H. influenzae type b diseases predominantly affecting children have decreased in many parts of the world. It has been reported that both encapsulated type b and noncapsulated (nontypeable) strains of H. influenzae might cause UTIs (6,7,11). In our case, the isolated strain was classified as serotype b.…”

Haemophilus influenzae, particularly in children, causes local and systemic infections such as meningitis, pneumonia, epiglottitis, otitis media, sinusitis and bacteremia. This bacterium has rarely been implicated as the causative agent of urinary tract infections (UTIs) in children. Most of the reported cases on UTIs due to H. influenzae were associated with urinary tract abnormalities and/or recurrent UTIs. Because of the inability of H. influenzae to grow in standard media commonly used for urine cultures, the true incidence of UTIs due to this potential pathogen is unknown. In this report, we present a case of UTI caused by H. influenzae in a 17-year-old boy with bilateral nephrolithiasis and hydronephrosis. To our knowledge, this is the first reported case of UTI caused by H. influenzae in Turkey. KEY wORdS: Haemophilus influenzae, Urinary tract infections, Urine ÖzHaemophilus influenzae, özellikle çocuklarda, menenjit, pnömoni, epiglottit, otitis media, sinüzit ve bakteriyemi gibi lokal ve sistemik enfeksiyonlara yol açmaktadır. Bu bakteri, çocuklarda üriner sistem enfeksiyonlarının (ÜSİ) etkeni olarak nadiren izole edilmiştir. H. influenzae'ye bağlı olarak gelişen ÜSİ ile ilgili bildirilen olguların çoğu, üriner sistem anormallikleri ve/veya tekrarlayan ÜSİ ile ilişkilendirilmiştir. H. influenzae'nın idrar kültürleri için yaygın olarak kullanılan standart besiyerlerinde ürememesi nedeniyle, bu potansiyel patojene bağlı olarak gelişen ÜSİ'nın gerçek insidansı bilinmemektedir. Bu raporda, bilateral nefrolitiyazisi ve hidronefrozu olan 17 yaşındaki bir erkek çocukta H. influenzae'ya bağlı olarak gelişen ÜSİ olgusunu sunuyoruz. Bildiğimiz kadarıyla, Türkiye'de bildirilen H. influenzae'nın etkeni olduğu ilk ÜSİ olgusudur. AnAhtAr sözcükler:Haemophilus influenzae, Üriner sistem infeksiyonları, İdrar

Haemophilus species are known to colonize the upper respiratory tract and can cause infections. However Haemophilus influenzae has been rarely described as a cause of genitourinary tract infection. We report a 44-year-old nonimmunocompromised Japanese man with bacteremic pyelonephritis caused by a nontypable H. influenzae associated with a left ureteral calculus. The organism was isolated from both blood and urine cultures. Treatment consisted of 14 days of intravenous ceftriaxone and oral amoxicillin one after than other and insertion of a left ureteral stent. After discharge, he underwent extracorporeal shock wave lithotrity for the left ureteral calculus. He had no recrudescence of the symptoms. H. influenzae should be considered as a genitourinary pathogen among patients with certain risk factors such as anatomical or functional abnormality of genitourinary tract. Collaboration between clinicians and microbiology laboratory personnel is essential for correct identification of the organism and appropriate therapy for genitourinary tract infections due to this organism.

Introduction: Haemophilus influenzae commonly causes upper respiratory tract infections and has only rarely been reported etiology of urinary tract infections. Since the introduction of the Haemophilus influenzae b (Hib) vaccine, non-typable haemophilus species now cause the majority of invasive disease in Europe.Case Report:We report a case of an adult man with non-typable Haemophilus influenzae septicemia, urinary tract infection and bilateral renal stone disease. The patient presented with right sided flank pain and a CT scan showed bilateral renal stones and a right sided ureteral stone causing obstruction.Results and Discussion: Haemophilus influenzae was identified in blood and urine and despite a tendency of increasing antibiotic resistance among Haemophilus influenzae, our strain was susceptible to all antibiotics tested. Treatment consisted of 3 days of intravenous cefuroxime, insertion of a right sided JJ ureteric stent and 5 days of peroral ciprofloxacin after discharge. Physicians and microbiologists should be aware of Haemophilus influenzae as a possible urinary tract pathogen, especially when urinary tract abnormalities are present, and take the risk of antibiotic resistance into consideration at initial treatment.
