The activity of lactate dehydrogenase (LDG), malate dehydrogenase (MDG), concentrations of lactic acid and lipid peroxidation (LPO) products in the blood serum and urine were estimated in 119 patients with acute pyelonephritis (70 cases of serous and 49 cases of purulent). The results of the study showed that acute pyelonephritis patients have activated anaerobic glycolysis. Ischemia leads to accumulation of lactic acid, activation of LPO. Significant differences between the groups of patients reflect strong influence of renaltissue ischemia on activity of systemic metabolic processes and metabolism in renal parenchyma. Standard infusion therapy was given to 30 patients with acute purulent pyelonephritis. 19 patients received solution of succinic acid reamberin. On day 4 of reamberin therapy plasma and urine activity of LDG and MDG attenuated, lactic acid concentration decreased, content of dienic conjugates was close to normal. Patients on reamberin treatment exhibited earlier relief of endogenic intoxication and improvement of blood count. Thus, succinic acid drugs reduce renal ischemia, improve a course of postoperative period in patients with acute purulent pyelonephritis.

The objective of the study is to examine the assumption that a process of hemolysis plays a role in anemia of acute infection in children. The study was comprised of febrile pediatric patients, who had a positive blood or urine culture. Complete blood count measures were compared between hospitalization and prehospitalization or posthospitalization values. Children admitted to the hospital for elective surgical procedures served as controls. Blood parameters of hemolysis were investigated in some of the patients. Of the 70 patients studied, 49 (70%) were diagnosed with pyelonephritis and 21 (30%) had bacteremia. Mean (+/-SD) hemoglobin (Hgb) on hospital admission was 10.9+/-1.27 g/L as compared with 12.1+/-1.03 g/L of the controls, P<0.0001. Compared with normal-for-age Hgb values as a standard, 42 (60%) cases were identified as anemic. Compared with hospitalization values, Hgb and hematocrit (Hct) were significantly higher in prehospitalization or posthospitalization, whereas WBC values were significantly lower. All parameters of hemolysis, namely reticulocytes, bilirubin, lactate dehydrogenase (LDH), and haptoglobin, were normal. Bacteremia and pyelonephritis are accompanied by a significant drop in Hgb level. There is no evidence of hemolytic anemia in these patients.

Urinary tract infections may induce severe inflammation, transient impairment in renal function and scar formation, ranging in severity from acute symptomatic pyelonephritis to chronic pyelonephritis, and have the potential to lead to renal failure and death. In the present study, the relationship between production of tumour necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), neutrophil recruitment, bacterial colonization and tissue damage was investigated using a mouse model of acute ascending pyelonephritis induced with planktonic and biofilm cells of Pseudomonas aeruginosa. Neutrophil influx correlated with rise in TNF-alpha and IL-1beta, indicating an association between these cytokines and neutrophil infiltration. However, biofilm cells of P aeruginosa induced higher levels of TNF-alpha and IL-1beta leading to higher neutrophil infiltration causing tissue damage, assessed in terms of malondialdehyde, lactate dehydrogenase and glutathione content, which may have contributed to bacterial persistence compared with their planktonic counterparts. The results of the present investigation suggest that exaggerated cytokine production during P aeruginosa-induced pyelonephritis causes tissue damage operative through neutrophil recruitment leading to bacterial persistence in host tissues. The findings of the present study may be relevant for the better understanding of disease pathophysiology and for the future developments of preventive strategies against pyelonephritis based on anti-inflammatory intervention.

BACKGROUND This is a case report of a male patient who presented with a history of right flank pain based on renal infarction. Initially the symptoms were misdiagnosed as acute pyelonephritis. CASE REPORT A 47-year-old male with a history of familial hypercholesterolemia and cerebral infarction presented at the Emergency Department with a 3-day history of acute right-sided flank pain. Physical examination revealed hypertension, subfebrile temperature, and costovertebral angle tenderness. Blood tests were unremarkable except for renal impairment, a high C-reactive protein level of 215 mg/L (normal <8 mg/dL) and an elevated lactate dehydrogenase (LDH) of 1289 U/L (normal <248 U/L). Renal ultrasonography was normal. He was admitted with a presumed diagnosis of acute pyelonephritis and treated accordingly. However, 2 days later, we rejected this diagnosis as the urine culture was sterile. Based on the acute onset of symptoms and the initial high LDH, renal infarction was suspected. A computed tomography scan confirmed right-sided partial renal and splenic infarctions likely due to spreading emboli from atherosclerosis of the descending aorta. CONCLUSIONS Acute renal infarction is often missed or delayed as a diagnosis because patients often present with flank pain that can resemble more frequently encountered conditions such as pyelonephritis and nephrolithiasis. Renal infarction should be considered in cases with acute flank pain accompanied by (low-grade) fever, high LDH level, increased C-reactive protein level, hypertension, and renal impairment, especially in those patients with an increased risk of thromboembolism.
