Management and treatment of Aerococcus bacteremia and endocarditis.

OBJECTIVES: We describe our multicenter experience on diagnosis and management of Aerococcus bacteremia including the susceptibility profile of Aerococcus species and a suggested algorithm for clinicians. METHODS: Retrospective study of all patients with positive blood cultures for Aerococcus species from January 2005 to July 2020 in our institution with clinical data and susceptibility profile. Data were collected from both electronic health record and clinical microbiology laboratory database. RESULTS: There were 219 unique isolates with only the susceptibility profiles available, while 81 patients had clinical information available. Forty-nine of those cases were deemed as true bloodstream infection and the rest were of unclear clinical significance. Cases of endocarditis (n = 7) were high-grade, monomicrobial bacteremia caused by Aerococcus urinae. Patients with endocarditis were younger (66 vs 80 p < 0.05). The risk for endocarditis was higher if duration of symptoms was longer than 7 days (OR 105, 95% CI: 5-2271), or if there were septic emboli (OR 71, 95% CI: 3-1612). A DENOVA score cutoff of ≥ 3 was 100% sensitive and 89% specific in detecting endocarditis. The 30-day and 3-month all-cause mortality for bacteremia was 17% and 24%, respectively. Six out of seven patients with endocarditis survived. CONCLUSIONS: Antibiotic regimen for aerococcal bloodstream infections and endocarditis should be guided by species identification and antimicrobial susceptibility testing. DENOVA scoring system's performance in this study is more congruent to other studies. Hence, it can be used as an adjunctive tool in assessing the need for echocardiogram to rule out endocarditis. In our experience, two and four weeks of treatment for bloodstream infections and endocarditis, respectively, had good outcomes.

The First Report of Calcified Amorphous Tumor Associated with Infective Endocarditis: A Case Report and Review of Literature.

BACKGROUND Calcified amorphous tumor (CAT) of the heart is a rare non-neoplastic intracardiac mass, which is composed of calcium deposition surrounded by amorphous fibrous tissue. The clinical presentation of cardiac CAT resembles that of other cardiac tumors or vegetation, though there is no previous report of a CAT complicated with infective endocarditis. CASE REPORT A 67-year-old male with a history of end stage renal failure and gastric cancer who was on adjuvant chemotherapy presented with a cardiac mass. The mass was resected and diagnosed as CAT pathologically. Two separate sets of blood cultures were positive for Enterococcus faecalis, thus, the patient was diagnosed with infective endocarditis. Antibiotic treatment was continued for 6 weeks after surgery, and the patient recovered uneventfully. However, he died from a complication of his gastric cancer 5 months later. CONCLUSIONS This is the first report of CAT associated with infective endocarditis. Blood cultures should be obtained to differentiate infective endocarditis or CAT with infectious endocarditis from CAT alone, because CAT with infective endocarditis may present atypically and may be more likely to require antibiotic treatment along with surgery.

Identification and antimicrobial susceptibility testing of Gram-positive and Gram-negative bacteria from positive blood cultures using the Accelerate Pheno™ system.

Rapid identification and antimicrobial susceptibility testing remain a crucial step for early efficient therapy of bloodstream infections. Traditional methods require turnaround times of at least 2 days, while rapid procedures are often associated with extended hands-on time. The Accelerate Pheno™ System provides microbial identification results within 90 min and susceptibility data in approximately 7 h directly from positive blood cultures with only few minutes of hands-on time. The aim of this study was, therefore, to evaluate the performance of the Accelerate Pheno™ System in identification and antimicrobial susceptibility testing of both Gram-positive and Gram-negative bacteria directly from clinical blood culture samples. We analyzed 108 and 67 blood culture bottles using the Accelerate PhenoTest™ BC kit with software version v1.0 and the FDA-cleared version v1.2, respectively. Reliable identification was achieved for Enterobacteriaceae, staphylococci, and enterococci, with 76/80 (95%), 42/46 (91%), and 10/11 (91%) correct identifications. Limitations were observed in the identification of streptococci, including Streptococcus pneumoniae and Streptococcus pyogenes, and coagulase-negative staphylococci. Antimicrobial susceptibility results for Enterobacteriaceae, for amikacin, ertapenem, ciprofloxacin, gentamicin, meropenem, and piperacillin-tazobactam ranged between 86 and 100% categorical agreement. Using v1.2, results for ceftazidime showed 100% concordance with the reference method. For staphylococci, the overall performance reached 92% using v1.2. Qualitative tests for detection of methicillin or macrolide-lincosamide-streptogramin B (MLSB) resistance caused major and very major errors for isolates. Overall, the present data show that the Accelerate Pheno™ system can, in combination with Gram stain, be used as a rapid complementation to standard microbial diagnosis of bloodstream infections.

Prevalence and Predictors of Third-Generation Cephalosporin Resistance in the Empirical Treatment of Spontaneous Bacterial Peritonitis.

OBJECTIVE: To better characterize the changing patterns of spontaneous bacterial peritonitis (SBP) in a tertiary academic center in the United States by identifying the prevalence of gram-positive organisms and cephalosporin resistance along with predictors of mortality and antibiotic drug resistance. PATIENTS AND METHODS: We reviewed 481 consecutive patients with SBP at Mayo Clinic in Rochester, Minnesota, from January 1, 2005, through December 31, 2016. Data on comorbid conditions, etiology of cirrhosis, factors predisposing to infection, and antimicrobial and antibiotic drug use were collected. RESULTS: We identified 96 patients (20%) with culture-positive SBP requiring treatment (median age, 60 years; age range, 22-87 years; 44% men). Gram-positive organisms account for more than half of the cases. Overall resistance to third-generation cephalosporins was 10% (n=10). Risk factors for third-generation cephalosporin resistance include nosocomial acquisition, recent antibiotic drug use, and hepatocellular carcinoma. The negative predictive value for antibiotic drug resistance in the present model was 96% (70 of 73). Overall mortality at 30 and 90 days was 23% and 37%, respectively. CONCLUSION: These findings support the recent observation of a rising prevalence of gram-positive organisms in SBP. Despite the changing pattern, third-generation cephalosporins seem to provide adequate empirical treatment in patients with community-acquired and health care-associated SBP without hepatocellular carcinoma.

Diabetic Foot Infection: Causative Pathogens and Empiric Antibiotherapy Considerations-The Experience of a Tertiary Center.

Most moderate-to-severe diabetic foot infections (DFIs) require hospitalization with urgent surgical approach and administration of empiric antibiotherapy. To ensure optimal antibiotic coverage, regular microbiological background updates are imperative. The purpose is to characterize the microbiological profile and the antibiotic sensitivity pattern of the DFI causative pathogens isolated within a specialized DFI unit of a tertiary hospital, in order to establish evidence-based policies regarding empirical antibiotic use. A cross-sectional study was conducted. Microbiological cultures and corresponding antibiotic sensitivity tests collected from moderate-to-severe DFIs as a first approach to the hospitalized patient were retrieved and analyzed during a 12-month period. Two groups were analyzed: inpatients that had been previously followed at the diabetic foot clinic of the hospital and inpatients without a previous contact with the hospital services. A total of 125 isolates obtained from 87 patients were deemed for analysis. Globally, a predominance of Gram-positive bacteria was observed (60%). Staphylococcus aureus was the most common pathogen. The global ratio of methicillin-sensitive S aureus to methicillin-resistant S aureus (MRSA) was 1.3:1, with similar findings in both groups. According to the antibiotic sensitivity test results, and within the recommended empiric antibiotic regimens for DFI, piperacillin/tazobactam seems to be the most suitable option. Gram-positive bacteria prevail as the main isolates in DFIs. Screening for MRSA-specific risk factors is mandatory. When going for a first empiric therapy, piperacillin/tazobactam is recommended in this institution, and an anti-MRSA agent should be added early, if necessary. We encourage continuous monitoring for the bacterial prevalence in Portuguese diabetic foot centers as it is paramount for the decision making regarding DFI protocols.

Slackia exigua, an anaerobic Gram-positive rod and part of human oral microbiota associated with periprosthetic joint infection of the hip. First case and review of the literature.

We report on the first case of a periprosthetic joint infection with the anaerobic Gram-positive rod Slackia exigua as the causative agent. The bacterium is part of human oral microbiota and has so far mainly been associated with periodontal diseases.

Urinary tract infections in febrile children: Changing spectra of pathogenic bacteria and antibiotic susceptibilities?

AIM: To compare the spectra of pathogens causing febrile urinary tract infections (UTI) in children, treatment and antimicrobial susceptibility between 2004-2006 and 2007-2009. METHODS: UTI were identified from a cohort study of febrile children younger than 5 years presenting to a large tertiary children's hospital's emergency department with febrile illnesses. We compared pathogenic profiles, antibiotic choices and susceptibilities between 2004-2006 and 2007-2009 and tested for differences using χ2 and Fisher's exact tests. Antibiotic choice was compared with national therapeutic guideline recommendations for UTI in children (oral cotrimoxazole, cephalexin or amoxycillin-clavulanate or intravenous gentamicin plus ampicillin). RESULTS: There were 539 (2.71%) confirmed UTI from 19 889 febrile illnesses in 2004-2006 and 654 (2.99%) confirmed UTI from 21 846 febrile illnesses in 2007-2009. There was no difference in the frequency of the isolated pathogens by period: Escherichia coli (69.2 vs. 69.7%, P = 0.85), Proteus mirabilis (7.9 vs. 7.2%, P = 0.66) and Klebsiella species (6.2 vs. 4.7%, P = 0.25). National therapeutic guideline recommendations were followed in 277 of 539 (51.4%) versus 318 of 654 (48.6%) (P = 0.34). Oral antibiotics were given in 20.6 versus 18.9%. There was no difference in extended spectrum beta lactamase (1.5 vs. 1.7%, P = 0.82) or other antibiotic susceptibilities (e.g. E. coli: cotrimoxazole = 75.9 vs. 75.2%, P = 0.8). CONCLUSIONS: Overall, approximately 3% of febrile illnesses were due to UTI, but we found no change in the spectrum of pathogens or antibiotic susceptibility patterns, including extended-spectrum beta-lactamase, with time. In both time periods, treatment followed therapeutic guidelines approximately half the time, and most pathogens were susceptible to oral antibiotics, but they were infrequently used.

Evaluation of the in vitro growth of urinary tract infection-causing gram-negative and gram-positive bacteria in a proposed synthetic human urine (SHU) medium.

Bacteriuria is a hallmark of urinary tract infection (UTI) and asymptomatic bacteriuria (ABU), which are among the most frequent infections in humans. A variety of gram-negative and gram-positive bacteria are associated with these infections but Escherichia coli contributes up to 80% of cases. Multiple bacterial species including E. coli can grow in human urine as a means to maintain colonization during infections. In vitro bacteriuria studies aimed at modeling microbial growth in urine have utilized various compositions of synthetic human urine (SHU) and a Composite SHU formulation was recently proposed. In this study, we sought to validate the recently proposed Composite SHU as a medium that supports the growth of several bacterial species that are known to grow in normal human urine and/or artificial urine. Comparative growth assays of gram-negative and gram-positive bacteria E. coli, Pseudomonas aeruginosa, Proteus mirabilis, Streptococcus agalactiae, Staphylococcus saprophyticus and Enterococcus faecalis were undertaken using viable bacterial count and optical density measurements over a 48h culture period. Three different SHU formulations were tested in various culture vessels, shaking conditions and volumes and showed that Composite SHU can support the robust growth of gram-negative bacteria but requires supplementation with 0.2% yeast extract to support the growth of gram-positive bacteria. Experiments are also presented that show an unexpected but major influence of P. mirabilis towards the ability to measure bacterial growth in generally accepted multiwell assays using absorbance readings, predicted to have a basis in the release of volatile organic compound(s) from P. mirabilis during growth in Composite SHU medium. This study represents an essential methodological validation of a more chemically defined type of synthetic urine that can be applied to study mechanisms of bacteriuria and we conclude will offer a useful in vitro model to investigate the basis of some of the most common infections of humans.

Antibiogram for Periprosthetic Infections: A Tool for Better Informed Selection of Empiric Antibiotics for Surgical Site Infections.

INTRODUCTION: Periprosthetic infection after breast reconstruction is not an uncommon complication, with incidence up to 24%. These infections are often treated empirically without knowing the causative bacteria or its sensitivities to various antibiotics. Even if cultures are obtained, results may not be available for several days. METHODS: A retrospective chart review of 553 patients at a single institution between January 2009 and July 2014 was performed, identifying patients who (1) underwent implant-based breast reconstruction and subsequently suffered an infection and (2) had cultures available with sensitivities. We reviewed patient demographics, implant characteristics, prophylactic intravenous antibiotics, oral antibiotic maintenance used, microbiologic details, and outcomes. The goal was to identify the most common causative bacteria, as well as their sensitivities to commonly used antibiotics, to help guide antibiotic decision-making. RESULTS: Of the 553 patients who underwent implant-based reconstruction, 114 (20.6%) patients suffered periprosthetic infections. Of these patients, 32 (28.1%) patients (56 reconstructions, with 33 tissue expanders and 23 implants) had cultures performed revealing 43 bacterial species, with the most common being Staphylococcus aureus (23.2%) and Pseudomonas aeruginosa (26.8%). Ceftazidime and piperacillin/tazobactam were equally effective covering 100% of Pseudomonas, enteric, and atypical organisms (P = 1), whereas vancomycin covered 100% of gram-positive organisms. Trimethoprim/sulfamethoxazole covered 100% of S. aureus, whereas clindamycin only covered 71% of S. aureus (P = 0.03). Additionally, trimethoprim/sulfamethoxazole was better able to cover atypical and enteric organisms. Ciprofloxacin covered 71% of Pseudomonas compared with 56% for levofloxacin (P = 0.14). Interestingly, cephalexin, a common choice for perioperative prophylaxis, was highly ineffective for gram-positive species in patients who later returned with infections. CONCLUSIONS: This study supports the efficacy of current intravenous antibiotics protocols but questions the efficacy of both clindamycin and levofloxacin in empirically treating periprosthetic infections and cephalexin in providing effective perioperative prophylaxis against skin flora. Because bacterial sensitivities vary by location and patient population, this study encourages other centers to develop their own antibiogram specifically tailored to periprosthetic infections to improve antimicrobial decision making and potentially improve implant salvage.

Microbial causes of complicated acute bacterial rhinosinusitis and implications for empirical antimicrobial therapy.

OBJECTIVES: Very little up-to-date information is available on the microbiology of complicated acute bacterial rhinosinusitis. Reliable microbiology testing is necessary to inform current empirical antimicrobial treatments. This study was conducted in response to recent US guidelines on antimicrobial treatments for acute bacterial rhinosinusitis. It aimed to describe the pathological micro-organisms involved in complicated acute bacterial rhinosinusitis in the UK and their antimicrobial susceptibility. METHODS: This study collected retrospective data on cases of complicated acute bacterial rhinosinusitis with sinogenic orbital and/or intracranial infections from 2007 to 2012. Bacteria identified in paranasal sinus pus were compared with those identified in orbital and/or intracranial infections. RESULTS: Streptococcus anginosus group bacteria were isolated from 61.3 per cent of paranasal sinus pus samples, 83.3 per cent of orbital infections and 77.8 per cent of intracranial infections. All S anginosus isolates were sensitive to penicillin; no penicillin-resistant organisms were isolated. CONCLUSION: S anginosus was the predominant organism isolated from complicated acute bacterial rhinosinusitis samples at our UK centre. S anginosus is sensitive to penicillin, suggesting that penicillin can be used as an appropriate first-line empirical antibiotic for uncomplicated acute bacterial rhinosinusitis.

Primary actinomycosis of the breast caused by Actinomyces turicensis with associated Peptoniphilus harei.

Actinomycosis of the breast is a rare disease which may mimic malignancy in presentation. Clinical presentation may make it difficult to distinguish primary actinomycosis from mastitis and inflammatory carcinoma. A 22-year-old lady presented with a 3-week history of right breast pain and greenish discharge through her nipple piercing. Physical examination revealed a palpable fluctuant lump in the upper inner quadrant of the right breast and a nipple jewelry in-situ in the upper inner quadrant of the right breast with an abscess at the edge of the areola. Needle aspiration was performed and microbiological examination of the aspirate isolated Actinomyces turicensis and Peptoniphilus harei. Actinomycosis of the breast is rare and the specie, Actinomyces turicensis, is even rarer especially in association with Peptoniphilus harei. Actinomyces is a difficult organism to treat due to its relative indolent course with potential scarring and disruption of local tissue. However, surgical intervention could be avoided with an intensive course of high-dose intravenous antibiotics and prolonged oral antibiotics afterwards.

Endophthalmitis caused by Enterococcus faecalis: clinical features, antibiotic sensitivities, and outcomes.

PURPOSE: To report the clinical features, antibiotic sensitivities, and visual acuity outcomes of endophthalmitis caused by Enterococcus faecalis. STUDY DESIGN: Retrospective, observational case series. METHODS: A consecutive case series of patients with culture-positive endophthalmitis caused by E. faecalis between January 1, 2002, and December 31, 2012, at an academic referral center. RESULTS: Of 14 patients identified, clinical settings included bleb association (n = 8), occurrence after cataract surgery (n = 4), and occurrence after penetrating keratoplasty (n = 2). All isolates were vancomycin sensitive. When comparing isolates in the current study with isolates from 1990 through 2001, the minimal inhibitory concentration required to inhibit 90% of isolates increased for ciprofloxacin (4 µg/mL from 1 µg/mL), erythromycin (256 µg/mL from 4 µg/mL), and penicillin (8 µg/mL from 4 µg/mL), indicating higher levels of resistance. The minimal inhibitory concentration required to inhibit 90% of isolates remained the same for vancomycin (2 µg/mL) and linezolid (2 µg/mL). Presenting visual acuity ranged from hand movements to no light perception. Initial treatment strategies were vitreous tap and intravitreal antibiotic injection (n = 12) and pars plana vitrectomy with intravitreal antibiotic injection (n = 2). Visual acuity outcomes were 20/400 or worse in 13 (93%) of 14 patients. CONCLUSIONS: Although all isolates were sensitive to vancomycin and linezolid, higher minimal inhibitory concentration required to inhibit 90% of isolates in the current study, compared with isolates from 1990 through 2001, occurred with ciprofloxacin, erythromycin, and penicillin. Despite prompt treatment, most patients had poor outcomes.

Vancomycin-variable Enterococcus faecium: in vivo emergence of vancomycin resistance in a vancomycin-susceptible isolate.

We report the emergence of vancomycin resistance in a patient colonized with a vanA-containing, vanRS-negative isolate of Enterococcus faecium which was initially vancomycin susceptible. This is a previously undescribed mechanism of drug resistance with diagnostic and therapeutic implications.

Prosthetic knee arthritis due to Granulicatella adiacens after dental treatment.

We report prosthetic knee arthritis in a 55-year-old diabetic man due to Granulicatella adiacens, a micro-organism present in the oral flora, usually described in endocarditis but rarely in prosthesis joint infection. This patient had undergone a dental extraction without antibiotic prophylaxis one month before, and an aseptic loosening of the prosthesis had been diagnosed previously. If antimicrobial prophylaxis against infective endocarditis for dental procedures is well established, such an approach is still controversial for joint prosthesis and should be considered in some conditions.

Infective endocarditis caused by Enterococcus faecalis treated with continuous infusion of ampicillin without adjunctive aminoglycosides.

Aminoglycosides are useful antimicrobial agents for treating infective endocarditis; however, they occasionally cause troublesome side effects, such as nephrotoxicity and ototoxicity. We herein report a case of infective endocarditis caused by Enterococcus faecalis that was treated successfully with continuous infusion of ampicillin without adjunctive aminoglycosides. The serum ampicillin concentrations were higher than the minimal inhibitory concentration for the target strain. Although the use of ampicillin monotherapy is currently avoided because double ß-lactam therapy is reportedly more effective, continuous penicillin administration remains an effective therapeutic choice for treating infective endocarditis.

[Emergence of glycopeptide resistant Enterococcus faecium in Algeria: a case report]. / Émergence d'Enterococcus faecium résistant aux glycopeptides en Algérie : à propos d'un cas.

A glycopeptide-resistant Enterococcus faecium (EFRG) was isolated from a wound in a patient hospitalized in a university hospital in Algiers. This strain was resistant to several antibiotics. This patient was carrying this strain in the digestive tract which may partly explain its origin. Genotypic comparison of the two strains by pulsed field gel electrophoresis showed that it was the same strain. Glycopeptide resistance was due to the presence of the vanA gene. Vigilance is required facing the emergence of strains of EFRG in our hospitals.

Empiric antibiotics pending bronchoalveolar lavage data in patients without pneumonia significantly alters the flora, but not the resistance profile, if a subsequent pneumonia develops.

INTRODUCTION: Ventilator-associated pneumonia (VAP) occurs in up to 25% of mechanically ventilated patients, with an associated mortality up to 50%. Early diagnosis and appropriate empiric antibiotic coverage of VAP are crucial. Given the multitude of noninfectious clinical and radiographic anomalies within trauma patients, microbiology from bronchioalveolar lavage (BAL) is often needed. Empiric antibiotics are administered while awaiting BAL culture data. Little is known about the effects of these empiric antibiotics on patients with negative BAL microbiology if a subsequent VAP occurs during the same hospital course. METHODS: This is a retrospective chart review of intubated trauma patients undergoing BAL for suspected pneumonia over a 3-y period at a Level 1 trauma center. All patients with suspected VAP undergoing a BAL receive empiric antibiotics. If microbiology data are negative at 72 h, all antibiotics are stopped; however, if the BAL returns with ≥10(5) colony-forming units per milliliter, the diagnosis of VAP is confirmed. We divided patients into three groups. Group 1 consisted of patients in whom the initial BAL was positive for VAP. Group 2 consisted of patients with an initial negative BAL, who subsequently developed VAP at a later point in the hospital course. Group 3 consisted of patients with negative BAL who did not develop a subsequent VAP. RESULTS: We obtained 499 BAL specimens in 185 patients over the 3-y period. A total of 14 patients with 23 BAL specimens initially negative for VAP subsequently developed VAP later during the same hospital stay. These patients did not have an increase in the hospital length of stay, intensive care unit days, ventilator days, or mortality compared with those who had a positive culture on the first suspicion of VAP. There was a significant increase in the percentage of Enterobacter (21% versus 8%) and Morganella (8% versus 0%) as the causative organism in these 14 patients when the VAP occurred. Furthermore, the profile of the top two organisms in each group changed. Enterobacter (21%) and Pseudomonas (17%) were the principal organisms in the initial BAL-negative group, whereas the two predominant strains in the initial positive BAL group were methicillin-sensitive Staphylococcus aureus (21%) and Haemophilus influenza (11%). Interestingly, methicillin-resistant S. aureus remained the third most common organism in both groups. Empiric antibiotics also did not seem to induce the growth of multidrug-resistant organisms, and there was no increased rate of secondary infections such as Clostridium difficile. CONCLUSIONS: Ventilator-associated pneumonia remains a significant cause of morbidity and mortality in mechanically ventilated trauma patients. The diagnosis and treatment of VAP continue to be challenging. Once clinically suspected, empiric coverage decreases morbidity and mortality. Our data demonstrate that patients who receive empiric coverage exhibit a significantly different microbiologic profile compared with those who had an initial positive BAL culture. Initial empiric antibiotics in BAL-negative patients were not associated with an increase in multidrug-resistant organisms, hospital, or intensive care unit length of stay, ventilator days, and mortality or secondary infections.

Early diagnosis and treatment of necrotizing fasciitis can improve survival: an observational intensive care unit cohort study.

BACKGROUND: The aim of this study was to describe the clinical characteristics, causative pathogens, clinical management and outcomes of patients presenting to a tertiary adult Australian intensive care unit (ICU) with a diagnosis of necrotizing fasciitis (NF). METHODS: This retrospective observational study was conducted in a 19-bed, level III, adult ICU in a 450-bed tertiary, regional hospital. Clinical databases were accessed for patients diagnosed with NF and admitted to The Geelong Hospital ICU between 1 February 2000 and 1 June 2011. Information on severity of sepsis, surgical procedures and microbiological results were collected. RESULTS: Twenty patients with NF were identified. The median age was 52.5 years and 38% were female. The overall mortality rate was 8.3%. Common co-morbidities were diabetes (21%) and heart failure (17%), although 50% of patients had no co-morbidities. Group A Streptococcus was the identified pathogen in 11 (46%) patients, and Streptococcus milleri group in 5 (21%) patients. Hyperbaric oxygen therapy was not used in the majority of patients. The initial antibiotics administered were active against subsequently cultured bacteria in 83% of patients. Median time to surgical debridement was 20 h. Diagnosis and management was delayed in the nosocomial group. CONCLUSIONS: This study reports physiological data, aetiology and therapeutic interventions in NF for an adult tertiary hospital. We demonstrate one of the lowest reported mortality rates, with early surgical debridement being achieved in the majority of patients. The main delay was found to be in the diagnosis of NF.

[Experience of use of prolit septo in the complex treatment of patients with urolithiasis].

The efficacy of phytogenic drug prolit septo in the complex treatment of patients with urolithiasis complicated by infectious-inflammatory process was evaluated. The effects of prolit septo were assessed by a comparative evaluation of the results of microbiological analysis of urine in 14 patients of main group and 12 patients of control group. Patients in both groups were matched by sex, age, and results of raiological, clinical, biochemical and microbiological methods of examination. For the treatment of 11 patients of the main group, prolit septo was applied in combination with standard anti-bacterial treatment, 3 patients received monotherapy with prolit septo within 3-6 weeks. The drug was administered at a dose of 1200 mg (2 capsules) 3 times a day. Twelve patients of the control group received only standard treatment. The duration of treatment in both groups was 1-2 weeks. It was found that combined therapy with prolit septo is more effective than standard antibacterial treatment. Against the background of combined therapy the disappearance of bacteriuria was noted in 54.5% of patients of main group compared with 8.3% of patients of control group.
