RESUMO

Burkholderia cepacia complex (BCC) is a well-recognized cause of nosocomial infections. We describe here a young healthy male who presented with fever and chest pain with ECG changes of acute pericarditis. Two sets of blood cultures at separate timings grew gram negative bacilli identified as BCC by molecular methods. The patient responded to intravenous ceftazidime despite high ceftazidime MIC's. The source of infection was probably contaminated nasal spray/nasal saline wash which he used after a balloon sinoplasty procedure one month ago. Issues related to accurate identification and susceptibility testing of BCC are also discussed.

RESUMO

Patients with lung cancer suffer frequent infections which not only thwart the effect of oncological treatment but also affect overall survival. We present a fatal case where coinfection of Pneumocystis jirovecii and Lophomonas blattarum caused pneumonia in a patient with advanced and treated metastatic adenocarcinoma of lung. Cytomegalovirus (CMV) PCR was positive for the patient. Newer pathogens are not only emerging but also there is an increase in incidence of coinfections. Pneumonia due to coinfection of Pneumocystis jirovecii and Lophomonas blattarum is rare and unusual and requires high degree of suspicion and skill for the diagnosis.

RESUMO

Introduction The growing resistance pattern of the gram-positive pathogens along with a steady increase in minimum inhibitory concentration of the currently available antibiotics have led to an increase in morbidity and mortality rates in India. This study aims to access the shifting antibiotic susceptibility paradigm of the gram-positive pathogens in various infections at a tertiary care center. Methods This is a 3-year retrospective observational study which was performed from January 2016 to December 2018 at a tertiary care hospital in Mumbai. All clinically significant gram-positive cocci isolated from a variety of clinical specimens were studied for their prevalence and antimicrobial susceptibility. Results Out of 4,428 gram-positive isolates, Staphylococcus aureus (35.3%) was the commonly encountered pathogen, followed by Enterococcus spp. (32.1%) and coagulase-negative Staphylococcus (CoNS) (25.7%). S. aureus was majorly isolated from skin and soft tissue infections (60.3%), followed by patients with respiratory tract infections (18.2%) and blood stream infections (13%). Among S. aureus , particularly methicillin-resistant S. aureus (MRSA), prevalence increased from 29.5% in 2016 to 35.1% in 2018, with an overall prevalence of 33.6%. All S. aureus isolates were 100% sensitive toward vancomycin, linezolid, tigecycline, and teicoplanin. However, the CoNS isolates showed a higher resistance rate with reduced susceptibility toward linezolid and teicoplanin. High prevalence of resistance was observed across gram-positive isolates with commonly used antibiotics such as ciprofloxacin, levofloxacin, and erythromycin. While the prevalence of linezolid-resistant enterococcus (LRE) was 3.6%, vancomycin (VRE) and teicoplanin resistance among the enterococcus species was as high as 7.7% and 7.5%, respectively. Conclusion Rising methicillin resistance among the Staphylococcal species (MRSA and MR-CoNS) along with reduced susceptibility toward currently available anti-MRSA agents is a matter of serious concern as it limits the therapeutic options for treating multidrug resistant (MDR) gram-positive infections.

RESUMO

PURPOSE: Antimicrobial resistance has emerged as a major public health problem in India. Hence effective antimicrobial stewardship programs (AMSP) are needed. We report the design, implementation and results of a prospective audit and feedback based AMSP at a private tertiary care hospital. METHODS: During the study period - January 2018 to December 2019 - the prescription of restricted antimicrobials required the filling of a justification form which was reviewed by the antimicrobial stewardship committee (AMSC) at 48-72 â€‹h. Patients in whom the restricted antimicrobial was stopped earlier than 48 â€‹h were not applicable for review. The eligible prescriptions were judged as justified/unjustified by AMSC based on the patient's clinical and previous antimicrobial history, course, results of investigations/cultures, guidelines and communicated to the treating team. Compliance to the recommendations of the AMSC was measured. Days of therapy for each restricted antimicrobial/1000 patient days was calculated. Colistin resistance rates in pathogens causing central line associated blood stream infections (CLABSI) were compared with previous years. RESULTS: A total of 2397 restricted antimicrobials in 1366 patients were prescribed in the study period of which 1801 prescriptions were applicable for review (75%). Overall, 1.4% of admitted patients were prescribed restricted antimicrobials. The total days of therapy with restricted antimicrobials was 41/1000 patient days. The AMSC committee adjudged 12.5% of prescriptions as unjustified and recommendations for de-escalation were accepted in 89%. There was no significant difference in the study outcomes between 2018 and 2019. CONCLUSION: The prospective audit and feedback component of AMSP provided insight into the use of restricted antimicrobials at our hospital. This component should be considered by hospitals for inclusion in their AMSP program on an ongoing basis even if limited to a few drugs and in few areas of the hospital.

RESUMO

There are several reports of Ct values of RT PCR assays for COVID 19 being associated with disease severity and infectivity. We studied the correlation between Ct values and disease severity and mortality at our hospital . All patients with RT PCR diagnosed COVID 19 illness admitted at the study site and for whom Ct values were available were included in the study. The patients with mild disease had significantly lower Ct values than patients with severe disease but had also been tested significantly earlier in the illness than those with severe disease. The patients who died had significantly lower Ct values than patients who survived but here again they had significantly shorter duration of symptoms before testing. We therefore recommend that the time of testing since onset of symptoms should be controlled for while correlating Ct values with disease severity.

RESUMO

Background: This study aims to study the incidence, microbial aetiology and antimicrobial susceptibility of surgical site infections (SSIs) at a private tertiary care hospital in Mumbai, India, and compare it with previously published data from the same institute as well as literature. Methods: This is a prospective observational study done over 6 years (January 2013-December 2018) at a 750-bed private multi-specialty hospital in Mumbai, India, among all patients undergoing clean and clean-contaminated surgeries. Standard guidelines for preventing, diagnosing and classifying SSIs were followed. The incidence rates of SSI (overall and specialty specific), microbial aetiology and antibiotic susceptibility of SSI were calculated and expressed as percentages. Results: A total of 55,553 patients underwent clean and clean-contaminated surgeries during the study period. The overall SSI rate was 1.0% (555 cases). The SSI rate in clean surgeries was 0.97% and in clean-contaminated surgeries was 1.03%. Sixty-five per cent of SSIs were due to Gram-negative bacilli, 30% were due to Gram-positive cocci and 4% were due to Candida. Klebsiella pneumoniae (19%), Escherichia coli (17%), Pseudomonas aeruginosa (13%), Staphylococcus aureus(12%) and Enterococcus (10%) were the top five organisms. The overall susceptibility rate of the Gram-negative isolates to beta-lactam-beta-lactamase inhibitor combinations was 60% and carbapenems was 73%. The prevalence of methicillin resistance in S. aureus was 44% and coagulase-negative Staphylococcus was 84%. The crude mortality rate was 1%. Conclusions: Although the SSI rate is comparable to established international benchmarks, the predominance of multidrug-resistant Gram-negative organisms is a matter of serious concern.

RESUMO

Healthcare worker (HCW) infections due to COVID-19 are of serious consequence. Testing for antibodies against COVID-19 in HCWs has been previously recommended. We conducted a serosurvey in HCWs at a private hospital in Mumbai which is treating COVID patients. A total of 244 HCWs were tested. The prevalence of infection in asymptomatic HCWs was 4.3% and in previously symptomatic untested HCWs was 70%. We recommend that HCWs with a previous history of COVID symptoms who were not tested/tested negative by reverse transcription-polymerase chain reaction should be tested for antibodies at least 2 weeks after onset of symptoms.

RESUMO

The current research project was undertaken to explore the therapeutic potential of two potent probiotic Lactobacillus fermentum strains, i.e., PD2 and PH5 in a hyperlipemic healthy adult Wistar rat model, with a particular focus as biotherapeutics for the management of high cholesterol in Indian population. Rats fed on cholesterol-enriched diet supplemented with potential probiotics strain Lactobacillus fermentum PH5 significantly affected serum lipid profile by reducing serum cholesterol (67.21%), triglycerides level (66.21%), and LDL cholesterol level (63.25%) in comparison to rats that received cholesterol-enriched diet (Model) only. Both the strains decreased the cholesterol levels in liver compared with Model group, but PH5 was found to be more effective (30.65% reduction) in liver total cholesterol (TC) lowering action. In addition, the fecal coliforms were significantly reduced besides increased LAB in feces of rats receiving probiotic curd having Lactobacillus fermentum PH5. Our results demonstrated that supplementation with either of the two strains was efficient in reducing serum cholesterol, LDL-cholesterol and TG concentrations in rats compared to those fed the same high-cholesterol diet but without LAB supplementation.

RESUMO

Background: There is a need to generate accurate data on temporal trends in incidence rates, aetiology and antimicrobial susceptibility of central line-associated bloodstream infections (CLABSIs) in the Indian setting. Aim: To study the incidence, aetiology and antimicrobial susceptibility of CLABSI in adult, paediatric and neonatal intensive care units (NICUs) in a tertiary care private hospital in Mumbai, India. Materials and Methods: This is a prospective observational study conducted at the adult, paediatric and NICUs of tertiary care private hospital from 2011 to 2018. CLABSI was defined as per the Centers for Disease Control criteria. Surveillance of CLABSI in the intensive care units (ICUs) was conducted using a form adapted from the International Nosocomial Infection Control Consortium surveillance system. The incidence rates of CLABSI (per 1000 central line days), crude mortality, aetiology and antimicrobial susceptibility were calculated and reported. Results: Six hundred and eighty-six episodes of CLABSI were recorded, and the overall incidence of CLABSI was 5/1000 catheter days, 4.1 in the adult ICU, 5 in the paediatric ICU and 9 in the newborn ICU. Crude mortality in patients with CLABSI in the adult, paediatric and NICUs was 45%, 30% and 7%, respectively. Of the 752 isolates, 80% were Gram negative, 10% Gram positive and 10% yeast. The prevalence of extended-spectrum beta-lactamase producers was 80%, and rates of carbapenem resistance were on an average 50%. Conclusions: The CLABSI rates at a well-equipped tertiary care hospital are still significantly higher than the USA benchmarks. Alarming rates of drug resistance in Gram-negative pathogens were seen.

RESUMO

PURPOSE: Clostridium difficile infection (CDI) is a serious healthcare-associated infection (HAI) now being increasingly reported from hospitals across India. However, there is a paucity of data on the incidence of and impact of control measures on CDI in India. MATERIALS AND METHODS: This is a retrospective study conducted at a tertiary care hospital in Mumbai from January 2016 to December 2017. All patients with healthcare-onset diarrhoea were tested for C. difficile by glutamate dehydrogenase (GDH)/toxin assay or nucleic acid amplification test (NAAT). CDI was defined as either GDH and toxin positive or NAAT positive. The incidence of CDI was calculated per 1000 patient days. Demographic features of patients with CDI including age, sex, duration of hospitalisation before onset of CDI, antibiotic use and treatment administered were summarised. RESULTS: A total of 67 patients had CDI in the study period with a mean incidence of 0.2/1000 patient days. A halving of the CDI incidence was seen after intensification of the CDI prevention bundle. The mean age of affected patients was 64 years and CDI occurred at a median duration of 2 weeks after hospitalisation. Eighty-seven per cent of the patients were on antibiotics at the time of diagnosis of CDI. The crude mortality rate was 22%. CONCLUSIONS: CDI is an emerging HAI in India. All hospitals need to set up policies for surveillance, testing, treatment and prevention of CDI based on recent international guidelines and local infrastructure/logistics.
