Purpose: Early diagnosis and treatment of acute pyelonephritis in children is of special importance in order to prevent serious complications. This study was conducted to determine the diagnostic value of serum interleukin (IL)-6 and IL-8 in children with acute pyelonephritis. Methods: Eighty-seven patients between 1 month to 12 years old with urinary tract infection (UTI) were divided into 2 groups based on the result of 99m-technetium dimercapto-succinic acid renal scan: acute pyelonephritis (n=37) and lower UTI (n=50) groups. White blood cell (WBC) count, neutrophil (Neutl) count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) concentration, platelet count, and serum IL-6 and IL-8 concentrations of both groups were measured and compared. Results: There was a significant difference between two groups regarding WBC count, Neutl count, ESR, and CRP concentration (P<0.05). In addition, the difference between the two groups regarding serum IL-6 and IL-8 concentrations was not significant (IL-6, 60 and 35.4 pg/mL and IL-8, 404 and 617 pg/mL, respectively). The sensitivity and specificity of serum IL-6 and IL-8 for diagnosis of acute pyelonephritis were 73%, 42% and 78%, 32%, respectively. Sensitivity, specificity, negative and positive predictive values of serum IL-6 and IL-8 were less than those of acute phase serum reactants such as CRP. Conclusion: This study showed that there was no significant difference between acute pyelonephritis and lower UTI groups regarding serum IL-6 and IL-8 levels. Therefore, despite confirming results of previous studies, it seems that IL-6 and IL-8 are not suitable markers for differentiating between acute pyelonephritis and lower UTI.

Patients with acute pyleonephritis may present with a spectrum of clinical symptoms and signs. There are few noninvasive diagnostic studies, however, to confirm or exclude this diagnosis. To evaluate the clinical utility of $^{99m}Tc-DMSA$ renal scan in diagnosis of acute pyelonephritis, we performed $^{99m}Tc-DMSA$ renal scan in 37 patients suspected with urinary tract infection. Simultaneously, kidney ultrasonography was done in 21 patients diagnosed with acute pyelonephritis, clinically. And we performed the followup scan after treatment in two to six weeks. The results were as follows: 1) $^{99m}Tc-DMSA$ renal scan disclosed single or multiple cortical defects and decreased radiouptake ratio of affected kidney in 23 patients among 25 patients diagnosed with acute pyleonephritis. 2) In the 21 patients with acute pyelonephritis, kidney ultrasonography showed abnormal finding in the 7 patients. And $^{99m}Tc-DMSA$ renal scan disclosed abnormal cortical defects in this 7 patients also. 3) Between the patients with acute pyelonephritis and those with lower urinary tract infection, asymptomatic bacteriuria or pyuria. right-to-left radiouptake ratios (R/L ratio) were significantly different (p < 0.001). 4) In two to six weeks after antibiotic therapy, we performed followup $^{99m}Tc-DMSA$ renal scan for 5 patients among 25 acute pyelonephritis patients. And we have found the improvement of cortical defects and the right-to-left radiouptake ratio. In conclusion, we thought that $^{99m}Tc-DMSA$ renal scan should be useful in diagnosis of acute pyelonephritis and follow-up examination.

Objectives: Serum procalcitonin (PCT) is a specific biomarker that rises after bacterial infection, and levels of PCT are known to correlate with the severity and mortality of patients with pneumonia and sepsis. However, the usefulness of PCT levels in acute pyelonephritis is unknown. This study aimed to evaluate the effectiveness of using the PCT level as a predictive test for bacteremia in acute pyelonephritis. Methods: Between January 2012 and June 2013, 140 patients diagnosed with acute pyelonephritis were admitted to Haeundae Paik Hospital. Serum PCT, C-reactive protein (CRP), and white blood cell (WBC) levels at pre- and post- treatment were measured. Blood and urine cultures were obtained from all patients. The levels of PCT, CRP, and WBCs were each compared between the blood culture-positive and blood culture-negative groups to assess their effectiveness in predicting bacteremia. Results: Pre-treatment PCT level was 0.77 ng/mL (95% CI: 0.42-1.60 ng/mL) in the blood culture-negative group and 4.89 ng/mL (95% CI: 2.88-9.04 ng/mL) in the blood culture-positive group, and the increase between the two groups was statistically significant. The area under the receiver operating characteristic curve of PCT level for prediction of bacteremia was 0.728. A cut-off value of 1.23 ng/mL indicated a sensitivity of 79.0 % and specificity of 60.0 % for PCT level. Conclusions: Serum PCT level is a useful predictive test for bacteremia in acute pyelonephritis. Through the early detection of bacteremia, serum PCT level can help estimate the prognosis and predict complications such as sepsis.

Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as one of the most promising biomarkers of renal epithelial injury. Numerous studies have presented the diagnostic and prognostic utility of urinary and plasma NGAL in patients with acute kidney injury, chronic kidney disease, renal injury after kidney transplantation, and other renal diseases. NGAL is a member of the lipocalin family that is abundantly expressed in neutrophils and monocytes/macrophages and is a mediator of the innate immune response. The biological significance of NGAL to hamper bacterial growth by sequestering iron-binding siderophores has been studied in a knock-out mouse model. Besides neutrophils, NGAL is detectable in most tissues normally encountered by microorganisms, and its expression is upregulated in epithelial cells during inflammation. A growing number of studies have supported the clinical utility of NAGL for detecting invasive bacterial infections. Several investigators including our group have reported that measuring NGAL can be used to help predict and manage urinary tract infections and acute pyelonephritis. This article summarizes the biology and pathophysiology of NGAL and reviews studies on the implications of NGAL in various renal diseases from acute kidney injury to acute pyelonephritis.

Shigella infection usually produces gastrointestinal symptoms but rarely causes urinary tract infection. A 7-year-old girl was admitted for fever, chills, right flank pain, and dysuria. She had no vomiting or diarrhea. There was mild tenderness in her right lower abdomen, and right CVA tenderness was also noted. Acute pyelonephritis was diagnosed by abdominal CT. She showed improvement with intravenous administration of antibiotics. The first urine culture grew $1{\times}10^5$ CFU/mL Shigella dysenteri. Although urinary tract infections due to Shigella species are extremely rare, Shigella species should be considered as a possible cause of pediatric urinary tract infection. We report the first case of urinary tract infection caused by S. dysenteri, which presented as acute pyelonephritis without gastrointestinal symptoms in a child.

Purpose: Early diagnosis and treatment of urinary tract infection have been emphasized to prevent renal scarring. If untreated, acute pyelonephritis could cause renal injury, which leads to renal scarring, hypertension, proteinuria, and chronic renal failure. The purpose of this study was to assess risk factors of renal scarring after treatment of acute pyelonephritis (APN). Methods: The medical records of 59 patients admitted at Daegu Fatima Hospital because of APN between March 2008 and April 2015 whose renal cortical defects were confirmed by using initial technetium-99m dimercaptosuccinic acid (DMSA) scans were reviewed retrospectively. We divided 59 patients into 2 groups according to the presence of renal scar and assessed risk factors of renal scar, including sex, age at diagnosis, feeding method, hydronephrosis, bacterial species, vesicoureteral reflux, and vesicoureteral reflux grade. Results: Of 59 patients (41%), 24 showed renal scar on follow-up DMSA scan. No significant differences in sex, hydronephrosis, bacterial species, and fever duration were found between the renal-scarred and non-scarred groups. As for age at diagnosis, age of >12 months had 5.8 times higher incidence rate of renal scarring. Vesicoureteral reflux (VUR) affected renal scar formation. VUR grade III or IV had 14.7 times greater influence on renal scar formation than VUR grade I or II. Conclusion: Our data suggest that the presence of VUR and its grade and age at diagnosis are risk factors of renal scar on follow-up DMSA scan after APN.

Purpose: In general, Acute Pyelonephritis is effectively treated with the use of antibiotics. However, some antibiotics are reported to cause side effects, and the abuse of antibiotics results in the increase of the disease's tolerance to antibiotics. Recently, I have effectively treated five cases of Acute Pyelonephritis by using only Constitution - Acupuncture and Herb, and therefore I would like to report about these cases. Methods: I diagnosed Acute Pyelonephritis of these five patients by confirming symptoms and employing a urine analysis with reagent strip(Multi $stix{\circledR}$). I used Kuon's method of constitutional diagnosis for the purpose of the diagnosis of the constitutional 8 morbidities. I relied on Sungjeong(性情) and Chehyungkisang(體刑氣像) in diagnosing Sasang Constitutions(四象人). I performed acupuncture on the left and right sides, depending on 8 constitutions, by employing Chang - temperament Inflammation Formula(臟系炎症方) that is used for the treatment of all kinds of chang-temperament inflammation diseases, as well as Bactericidal Formula(殺菌方) that is used for the treatment of all kinds of bacterially caused diseases. I prescribed by consulting the appearance of disease and general symptoms of each case with Dongyi Soose Bowon(東醫壽世保元)'s prescription symptoms. Result: Two of them showing severe symptoms were hospitalized, while three others took OPD treatment. The patient who was PANCREOTONIA and Soyangin improved through hospitalization for three days, another patient who was PULMOTONIA and Taeyangin with severe symptoms, improved through hospitalization for seven days, and completely recovered through OPD treatment later. The three others took only OPD treatment, and improved within 5-7 days. Conclusion: I confirmed that each of 8-constituions and Sasang Constitutions were all treated effectively without antibiotics.

SCH는 주로 낭종, 출혈 경향, 암, 혈관질환에 의해 발생하나 드물게 감염에 의해 발생할 수 있다. 본 증례는 기저질환으로 조절되지 않는 당뇨, 음주력이 있는 환자에서 급성 신우신염의 합병증으로 양측 SCH가 발생한 국내 첫 보고이다. CT를 통하여 양측 SCH를 진단하였고 원인 감별을 위한 검사 진행 후 감염이 원인임을 확인하였다. 항생제 치료와 더불어 패혈증, 파종성 혈관 내 응고에 대해 신대체 요법 진행 후 신기능 및 감염 소견이 호전되어 중단하였고 이후 양측 PCD를 통하여 혈성, 농양 배액을 30일간 유지한 뒤 제거 후 퇴원하였다. 본 사례는 양측 SCH의 드문 원인으로서 급성 신우신염이 가능함을 확인한 국내 첫 사례 보고라는 점에서 의의가 있다.
