Child with SARS-CoV-2 infection and acute lymfoblastic leukemia

Introduction. Coronavirus disease 2019 (COVID-19) frequently leads to asymptomatic or mild infectious disease evolution in children. Case presentation. We present the case of a 3 year old girl, known with acute lymphoblastic leukemia in chemotherapy treatment at that time. She had an asymptomatic form of COVID-19 but with important paraclinical changes. The evolution was favorable under the treatment initiated with antibiotics, corticotherapy, gastric protector and symptomatic treatment if necessary. Conclusion. Management of children with COVID-19 and other comorbidities remains a challenge given the few data currently in the literature.

SEVERE EVOLUTION WITH MULTIPLE SEPTIC DETERMINATIONS IN A PATIENT DIAGNOSED WITH STREPTOCOCCUS GALLOLYTICUS INFECTION

Streptococcus gallolyticus, member of streptococcus bovis group colonizes digestive tubes of birds, cows and human (2.5-15%). Literature describes the association between bacteriemia with Streptococcus gallolyticus and colon tumours but also extracolonic lesions (bacterial endocarditis, vertebral osteomyelitis, dyscitis, colangitis, lung tumors, ovarian tumors). We report the case of a 60 years old male caucasian patient who was diagnosed with vertebral osteomyelitis as the first lesion of Streptococcus gallolyticus infection identified by blood culture. Other lesions were diagnosed on aortic valve (bacterian endocarditis), right popliteal artery (popliteal artery thrombosis), right knee (arthritis). Even if there was a clinical and biological improvement during the treatment, the imaging tests done after 30 and 45 days from the diagnosis showed severe aortic insuficiency so surgical intervention for aortic valvuloplasty was done in a short time. Vertebral and popliteal artery lesions have improved within two months of antibiotic treatment. Colonoscopy, which was done 6 weeks from the diagnosis showed colonic polyps – risk factors of Streptococcus gallolyticus bacteriemia. This case proves that Streptococcus gallolyticus infection has a silent period followed by severe evolution by multiple septic lesions inspite of the precocious treatment and warn of the necessity of digestive investigations at these patients.

EVOLUŢIE SEVERĂ CU MULTIPLE DETERMINĂRI SEPTICE LA UN PACIENT DIAGNOSTICAT CU INFECŢIE CU STREPTOCOCCUS GALLOLYTICUS

Streptococcus gallolyticus, membru al grupului Streptococcus bovis (strepococ de grup D) colonizează tubul digestiv al păsărilor, animalelor rumegătoare şi om (2,5-15%). Este descrisă în literatură asocierea bacteriemiei cu Streptococcus gallolyticus cu tumori colonice şi manifestări extracolonice (endocardită bacteriană, osteomielită vertebrală, discită, colangite, tumori pulmonare, ovariene). Raportăm cazul unui pacient în vârstă de 60 ani, sex masculin, caucazian, la care infecţia cu Streptococcus Gallolyticus identificată prin hemocultură a avut ca primă manifestare osteomielită vertebrală. S-au identificat leziuni la nivelul valvei aortice (endocardită bacteriană), arterei politee dreapta (tromboză diagnosticată prin ecografie Doppler artere, angio CT membre pelvine), genunchi drept (artrită). Deşi evoluţia a fost favorabilă din punct de vedere clinic (afebrilitate, ameliorarea durerii lombare) şi biologic (scăderea leucocitozei, a sindromului inflamator, hemoculturile ulterioare au fost negative) repetarea investigaţiilor imagistice la 30 zile şi la 45 zile au arătat insuficienţă aortică severă ce a necesitat intervenţie chirurgicală pentru înlocuire de valvă aortică efectuată la 2 luni de la diagnostic. Leziunile de la nivelul coloanei vetebrale, arterei poplitee s-au ameliorat după 2 luni de tratament antibiotic. Colonoscopia efectuată la 6 săptămîni de la diagnostic a arătat prezenţa polipilor colonici – posibilă poartă de intrare pentru Streptococcus gallolyticus. Cazul prezentat demonstrează debutul silenţios al infecţiei cu Streptococcus gallolyticus, evoluţia ulterioarăseveră din cauza multiplelor determinări septice şi atrage atenţia asupra necesităţii efectuării explorărilor digestive (endoscopie digestivă superioară, colonoscopie) la pacienţii diagnosticaţi cu acest tip de infecţie.

Dinamic of resistance to antibiotics for the most frequent potential pathogen bacterial isolates in “Dr. V. Babes” Clinical Hospital of Infectious and Tropical Diseases (2000-2015)

Objective. Analyzing the dynamycs of global antibiotic resistance of some bacterial species isolated from patients admitted to the „Dr. V. Babes” Hospital for Infectious and Tropical Diseases, between the years 2000 to 2015. Material and methods. Antibiotic resistance profiles of bacteria isolated from inpatients, were identified by the standard diffusion method and MIC values by VITEK2C and E-test methods. (CLSI and EUCAST standards). Screening of carbapenemases – producing isolates were performed by phenotipic methods, and the confirmation by RealTimePCR: “MasterPure™ Complete DNA and RNA Purification Kit” (Epicentre), „Primer Design™ Kit” (blaOXA48; blaKPC, blaNDM, blaVIM)/ LightScanner 32 Instrument/LS32 (Idaho Technology), and GeneXpert. Internal quality control: Staphylococcus aureus ATCC29213, Streptococcus pneumoniae ATCC49619, E. coli ATCC25922, Pseudomonas aeruginosa ATCC27853. Results. The incidence of St. aureus meticilino-rezistent (MRSA) highlights an increase from 12.2% (2002) to 40.4% (2015). In the past 3 years SVB microbiology lab found a sharp increase in the incidence of erytromycin resistant strains of Streptococcus pyogenes. In 2015 we registered 20.3% of macrolide resistant strains. Global resistance to penicillin G for Str. pneumoniae (non-meningeal infections) was 45.3%- 54.5% until 2009, and 2.7% in 2013. Enterococcus faecium strains showed 0% resistance to vancomycin between 2000 and 2012. A significant growth was recorded in 2015 of 11%. Isolation rate of Klebsiella pneumoniae ESBL producing strains has increasewd progressively from 17.6 in 2000 to 57% in 2015. Carbapenems – resistant K. pneumoniae isolated strains were 18,8% in 2015. Carbapenemases types identified by phenotypic and genetic methods where: 35/ Oxa48, 8 KPC and 21/MBL (NDM-1). Resistance to carbapenems recorded an upward trend: 23.9% in 2004 to 37.9% in 2015, and for Acinetobacter baumannii 69%. Conclusions. Antibiotic resistance of bacteria is a major challenge for public healts. Therapeutic solutions are extremely limited.

Randomised clinical trial: alisporivir combined with peginterferon and ribavirin in treatment-naïve patients with chronic HCV genotype 1 infection (ESSENTIAL II)

BACKGROUND

Alisporivir (ALV) is an oral, host-targeting agent with pangenotypic anti-hepatitis C virus (HCV) activity and a high barrier to resistance.

AIM

To evaluate efficacy and safety of ALV plus peginterferon-α2a and ribavirin (PR) in treatment-naïve patients with chronic HCV genotype 1 infection.

METHODS

Double-blind, randomised, placebo-controlled, Phase 3 study evaluating ALV 600 mg once daily [response-guided therapy (RGT) for 24 or 48 weeks or 48 weeks fixed duration] or ALV 400 mg twice daily RGT with PR, compared to PR alone. Following a Food and Drug Administration partial clinical hold, ALV/placebo was discontinued and patients completed treatment with PR only. At that time, 87% of patients had received ≥12 weeks and 20% had received ≥24 weeks of ALV/PR triple therapy.

RESULTS

A total of 1081 patients were randomised (12% cirrhosis, 55% CT/TT IL28B). Addition of ALV to PR improved virological response in a dose-dependent fashion. Overall, sustained virological response (SVR12; primary endpoint) was 69% in all ALV groups vs. 53% in PR control. Highest SVR12 (90%) was achieved in patients treated with ALV 400 mg twice daily and PR for >24 weeks. Seven cases of pancreatitis were reported, with similar frequency between ALV/PR and PR control groups (0.6% vs. 0.8% respectively). Adverse events seen more frequently with ALV/PR than with PR alone were anaemia, thrombocytopenia, hyperbilirubinaemia and hypertension.

CONCLUSIONS

Alisporivir, especially the 400 mg twice daily regimen, increased efficacy of PR therapy in treatment-naïve patients with HCV genotype 1 infection. The mechanism of action and pangenotypic activity suggest that alisporivir could be useful in interferon-free combination regimens.

Alisporivir with peginterferon/ribavirin in patients with chronic hepatitis C genotype 1 infection who failed to respond to or relapsed after prior interferon-based therapy: FUNDAMENTAL, a Phase II trial

Alisporivir (ALV) is an oral, investigational host-targeting agent, with pangenotypic activity against hepatitis C virus (HCV). This randomized, double-blind, placebo-controlled, Phase II study explored the efficacy and safety of ALV with peginterferon-α2a/ribavirin (PR) in patients with chronic HCV genotype 1 infection in whom prior PR had failed (43% relapsers, 34% null responders and 23% partial responders). Four-hundred-and-fifty-nine patients were randomized (1:1:1:1) to ALV 600 mg once daily (QD), ALV 800 mg QD, ALV 400 twice daily (BID) or placebo plus PR for 48 weeks. When the global ALV trial programme was put on clinical hold, all patients in this study had received ≥31 weeks of randomized treatment; patients completed 48 weeks on PR alone. All ALV groups demonstrated superior rates of complete early virologic response (cEVR; primary endpoint) vs PR alone (P ≤ 0.0131), with highest cEVR rate seen with ALV 400 mg BID (74% vs 36% with PR alone; P < 0.0001). Respective SVR12 rates (key secondary endpoint) were 65% vs 26% in prior relapsers, 63% vs 5% in partial responders and 68% vs 3% in null responders. In patients who received >40 weeks of randomized treatment, the SVR12 rate was 89% for ALV 400 mg BID vs 30% for PR alone (P = 0.0053). Rates of viral breakthrough and relapse were lowest with ALV 400 mg BID. One case of pancreatitis (fully recovered) occurred with ALV/PR. Common AEs were headache, fatigue, anaemia, neutropenia and nausea. Hypertension was infrequent, but more common with ALV. ALV merits further investigation in interferon-free regimens in combination with direct-acting antiviral agents.

Plasmodium vivax malaria in a Romanian traveller returning from Greece, August 2011

In August 2011, a Plasmodium vivax malaria infection was diagnosed in a Romanian traveller returning from Greece. This case together with several reports over the past decade of autochthonous cases in Greece highlight that malaria should be considered as differential diagnosis in symptomatic travellers returning from this country. Travellers may serve as sentinels of emerging vector-borne diseases.

[Bacterial strains isolated from systemic infections and reported for evaluation and antibiotic resistance surveillance by the "Dr. Victor Babeş" Clinical Hospital for Infectious and Tropical Diseases, Bucharest]

AIM

Testing antibiotic resistance of bacterial strains (compulsor, reported for EARSS surveillance) isolated from patients hospitalised for systemic infection in the "Dr. V. Babe" Hospital for Infectious and Tropical Diseases during 01.01.2005-11.11.2009, for a dynamic evaluation and for the surveillance of resistance emergence for certain classes of antibiotics.

MATERIAL AND METHODS

Bacterial isolation: BacT/ALERT system; strain identification in classic and automated system (ATB Expression. VITEK 2C): antibioresistance: disk-difussion method (NCCLS 2005--CLSI 2009), MIC (E-Test, ATB/ Expression, VITEK 2C). Screening of ESBL-producing strains performed with double disk-difussion method (DDD). Reference strains used: S. aureus ATCC 25923, S. pneumoniae ATCC 49619, E. coli A TCC 25922, Enterococcus fiecalis ATCC 29212.

RESULTS

During the studied period, 245 bacterial strains have been isolated, identified and tested (Staphylococcus aureus / 70, Streptococcus pneumoniae / 61, Enterococcus faecalis / 18, Enterococcus faecium / 5, Neisseria meningitidis / 18, E. coli / 73). out of 166 hemocultures and 79 cerebrospinal fluids / CSF. The average incidence of MRSA strains in systemic infections was 34.28%. 44.28% of the S. aureus strains were resistant to erythromycin, 17.14% to cyprofloxacyne, 15.71% to rifampicine, 14.49% to gentamycine. No strain resistant to vancomycine and linezolide. Streptococcus pneumoniae presented an average high resistance to penicillin G of 11.47%. and a 1.63% resistance to third generation cephalosporines. 0% resistance to vancomycine and rifampicine. 7/ 18 Enterococcus faecalis strains and 4/5 Enterococcus faecium strains presented high level resistance to gentamycine (CN 120 microg/disk) and no strain was resistant to vancomycine, teicoplanin or linezolid. The 18 Neisseria meningitidis strains were all sensitive to beta-lactams, macrolides, fluoroquinolones and cloramphenicol. For the 73 Escherichia coli strains, the average incidence of ESBL-producing isolates was 10.95%, the average resistance to ampicillin was 58.90%, to gentamycine--13.88% and to cyprofloxacin--20.83%. No strain resistant to carbapenemes and amikacine.

CONCLUSIONS

For the systematic surveillance of antibiotic resistance there is a need for a harmonised protocol of data gathering and strain selection and the rigurous implementation of correct evaluating methods for antibiotic resistance in the microbiology laboratory. Carbapenemes. glycopeptides and oxazolidinones still present a major effectiveness in the first intention treatment of systemic infections.

[Use of systemic antibacterial agents at a university emergency clinic in Bucharest, in the year 2008]

OBJECTIVE

use of ATC/DDD (Anatomic Therapeutic Classification/Daily Defined Dose) methodology promoted by World Health Organization for calculating and analysis of systemic antimicrobial agents' annual rates of usage among the adult patients hospitalized in Bucharest municipality.

METHODS

descriptive retrospective study conducted in the main university clinic for medical emergencies from Bucharest municipality. Consumption of systemic antimicrobial agents, taken from the clinic pharmacy's records, regarding the 2008 year, has been transformed in defined daily doses and aggregated by ATC subgroups. The number of patient days from 2008 was obtained from clinic administrative service. Antimicrobial agents' usage was expressed as consumption density rate by dividing the defined daily doses counts to the correspondent number of patient days. Analysis of consumption rates has been performed both by whole clinic and also stratified by departments of medical specialties: surgery, internal medicine and intensive care.

RESULTS

In the year 2008, the patients carried in the clinic totalized 255,600 days of hospitalization; during the respective time in clinic there were used 36 of individual antibacterial agents that made up 184,857 defined daily doses. At the level of entire clinic the consumption rate of all systemic antimicrobial agents was 72.6 defined daily doses per 100 de patient days (DDD/PD); by medical specialties the indicator's values were 61.2 DDD/100 PD in the department of internal medicine specialties, 62.8 DDD/100 PD in the departament of surgical specialties and 126 DDD/100 PD in the medical/surgical intensive care unit, respectively. Almost 70% of the defined daily doses' total included five antimicrobial agents: co-amoxiclav, cefuroxim, cefoperazone + sulbactam, ciprofloxacine si metronidazol. By ATC subgroups, the top three consumption rates included penicillin plus beta-lactamase inhibitors, 2nd generation cefalosporines and fluorochinolons, respectively. Comparing the own rate with the distributions of NNIS (National Nosocomial Infection Surveillance) system form USA, demonstrated that the usage was into the expected limits for the majority of antimicrobial agents groups considered, excess usage being detected only in the case of 2nd generation cefalosporins (in non-intensive care sector) and in the case of carbapenems in the intensive care units, respectively.

CONCLUSIONS

At the whole clinic level, the study detected a rate of systemic antimicrobial agents' usage similar with the correspondent values recently reported even from the South European states or form USA. Excessive usage (against the NNIS standard) might be mitigated through augmentation of the compliance with guidelines for prudent utilization of antimicrobial agents.

Clinical effects of erdosteine in the treatment of acute respiratory tract diseases in children

Erdosteine has positive effects on mucus rheology and transport due to the active metabolite (Metabolite I) which contains a free thiol group. Erdosteine inhibits bacterial adhesiveness and has antioxidant properties. A synergistic effect of erdosteine with various antibiotics has been demonstrated in pharmacological and clinical studies. The present study was multicenter, randomized, double-blind and placebo-controlled. The aims of the study were to compare a combination of erdosteine with amoxicillin against an amoxicillin-placebo combination in pediatric patients with acute lower respiratory tract disease. A total of 158 patients (78 in the erdosteine group and 80 in the placebo group) were treated for 7 +/- 2 days. The efficacy parameters were cough (primary), polypnea, rhonchi, rales and body temperature (all measured at baseline, on Day 3 and at the end of treatment). Safety was assessed by strictly monitoring the occurrence of adverse events and using standard laboratory parameters. The results of the intention-to-treat analysis showed that the severity of cough was decreased by 47% at Day 3 in the erdosteine group with a statistically significant difference compared to placebo, the difference was still significant at the final visit. The decrease in the severity of rales was significantly greater at Day 3 in the erdosteine group than in the placebo group. The incidence of polypnea and rhonchi in the two groups showed similar decreases, an improvement mainly due to the antibiotic. No adverse events occurred and no adverse changes in laboratory parameters were observed. It is concluded that the combination of erdosteine and amoxicillin is a safe medication which is clinically superior to that of the antibiotic combined with placebo, especially in regard to the effects on cough.

Allele frequencies of 13 short tandem repeat (STR) loci in the Romanian population

A population study on 13 tetra- and pentameric STR loci (D3S1358, VWA, D8S1179, D21S11, D18S51, D16S539, D2S1338, D19S433, THO1, FGA, ACTBP2 (SE33), Penta D and Penta E) was performed with Romanians from the Bucharest area.

Clinical manifestations in the West Nile virus outbreak

During the summer of 1996 an unusual clustering of meningoencephalitis cases was recorded in the Capital City, Bucharest, and in some areas from South-East Romania. After an initial suspicion of an enteroviral etiology was discarded, the West Nile etiology was confirmed by specific antibodies demonstration through hemagglutination-inhibition and ELISA tests. This study included 251 patients with the diagnoses of West Nile acute encephalitis (166 cases), acute meningitis (57 cases) and acute febrile disease (33 cases). The patients' age ranged from 1 to 89 years (mean 51.1 years). The most frequent clinical manifestations were: fever (95.7% of cases), cephalalgia (92.6%), stiffness of the neck (89.1%), vomiting (62.5%), marked asthenia (46.5%), myalgia (28.9%). In addition, patients with encephalitis exhibited: alteration of consciousness (89.2% of cases), tremor of extremities (40.4%), ataxia (44%), paralysis (15.1%). The fatality rate was 15.1% in acute encephalitis, 1.8% in acute meningitis and 0% in the acute febrile disease.
