Antibiotic Susceptibility Pattern

Background: Chronic suppurative otitis media (CSOM) is a disease of mucoperiosteal lining of the middle ear cleft. The poor compliance of patients to antibiotic treatment, Incomplete treatment, misuse/improper choice of antibiotics have resulted in changes in susceptibility to antibiotics and also development of resistant strains by microbes to commonly used antibiotics. This study aimed to identify the mycobacteriological profile and determine antibiotic susceptibility pattern in CSOM patients.Methods: This cross sectional study was conducted on 120 clinically diagnosed cases of CSOM attending otolaryngology department. Ear discharges obtained were processed for microbial culture (aerobic, anaerobic and fungi). Antimicrobial susceptibility testing was done by Kirby–Bauer disc diffusion method. Results: Of total 120 cases, pathogens were isolated from 114 cases. The commonest aerobic organism isolated was Pseudomonas aeruginosa (34.5%) followed by Staphylococcus aureus (29.4%). Staphylococcus aureus showed maximum sensitivity to erythromycin (70%), followed by cotrimoxazole (62.5%) and ampicillin (55%). Maximum resistance was observed for ciprofloxacin (77.5%), followed by amoxiclave (55%). Pseudomonas aeruginosa showed maximum sensitivity to piperacillin (89.36%) followed by gentamicin (70.2%), amikacin (70.2%), moderate sensitivity to ceftazidime (51.06%); however resistance to carbpenicillin (60%). Ciprofloxacin which is the most prescribed topical antibiotic showing an increase in resistance to causative organisms of CSOM.Conclusions: Hence, it becomes essential to study each case of CSOM bacteriologically to formulate local antibiotic policy for appropriate use of antibiotics. This will certainly help in achieving a safe ear and to control the organisms developing resistance to prevalent antibiotics.

Background: Chronic suppurative otitis media (CSOM) is the most common middle ear infection characterized by recurrent ear discharges or otorrhoea through a tympanic perforation from the middle ear. The organisms isolated from CSOM include both aerobic and anaerobic bacteria. Among the bacteria, Pseudomonas aeruginosa (P. aeruginosa) has been particularly blamed for deep seated and progressive destruction of middle ear and mastoid structures through its toxins and enzymes. The present study was done to determine the prevalence and antibiotic susceptibility of P. aeruginosa isolated from CSOM.Methods: This was a retrospective study conducted in a tertiary care hospital in South India in March 2016. Data was obtained from the microbiology records from January 2014 to January 2016. Patients who had active ear discharge for at least three months were included in the study. P. aeruginosa was identified by colony morphology, pigment production, characteristic musty or earthy odor. The identification was confirmed by motility and standard biochemical tests. Results: A total of 293 cases of CSOM were included in the study. Microbial growth was seen in 248 (84.6%) cases and remaining 45 cases did not show any growth. Among 248 bacterial growth, 87 (35%) were positive for P. aeruginosa. Most common organism was P. aeruginosa followed by Staphylococcus aureus. Highest resistance was seen with Gentamicin and Ofloxacin and least resistance with Imipenem. The increased resistance to Cephalosporin group is warning sign, as these are potent anti-Psuedomals.Conclusions: P. aeruginosa and Staphylococcus aureus were found to be the common cause of CSOM in the present study. P. aeruginosa was resistant to commonly used antimicrobials. There was no resistance seen with Imipenem and only two strains were resistant to Piperacillin+tazobactum. Regular evaluation of the microbiological pattern and antibiogram of isolates will help in decreasing the complications of CSOM.

Background: Chronic suppurative otitis media is a disease affecting the middle ear and mastoid cavity, leading to considerable morbidity by causing hearing loss; and even life threatening complications in squamosal type of CSOM, if left untreated over long periods of time. Hence it is imperative to treat the persistent ear discharge in CSOM according to the antibiotic susceptibility of the organisms isolated. Methods: This is a prospective cross sectional study done in 135 patients of chronic suppurative otitis media presenting with active ear discharge. Sterile swabs were used to collect pus from discharging ear and sent for culture sensitivity. Results: Staphylococcus and Pseudomonas aeruginosa were the most common organisms isolated in this study. Pseudomonas aeruginosa was most sensitive to Piperacillin-Tazobactam, followed by Meropenem and Ciprofloxacin. Staphylococcus aureus was most sensitive to Linezolid followed by Cefoxitin and Erythromycin. Conclusions: Treating active discharge of CSOM according to pus culture sensitivity pattern reduces the bacterial load in the middle ear and makes the ear more favourable for graft uptake.

A Prospective Study

Medical management of chronic suppurative otitis media without cholesteatoma in children was shown recently to be efficacious. We undertook a prospective study in order to determine 1) the organisms associated with the disease and their sensitivity to various antibiotics and 2) their association with clinical variables. Pseudomonas was isolated from 84% of the patients, enteric gram-negative bacilli from 32%, Staphylococcus aureus from 20%, streptococci from 14%, and Hemophilus influenzae from 15%. Pseudomonas aeruginosa was the sole isolate in 48 of the 128 patients (38%). The sensitivity of P aeruginosa (78 isolates) was 100% (of isolates) to mezlocillin and ciprofloxacin, 99% to tobramycin and ceftazidime, 97% to piperacillin, 94% to gentamicin, and 78% to ceftriaxone. The isolated organisms and their sensitivity to antibiotics were not associated with age, sex, duration of otorrhea, or the presence of granulation tissue or polyps. We believe that our data may contribute to the appropriate choice of antibiotics when nonsurgical management of chronic suppurative otitis media without cholesteatoma is considered.

BACKGROUND: Chronic Suppurative Otitis Media (CSOM) causes hearing impairment and frequently occurred in low-income country where medical care and personal hygiene are poor. Staphylococcus aureus and Pseudomonas aeruginosa are the most common cause of CSOM. We investigated prevalence and antimicrobial susceptibility of S. aureus and P. aeruginosa from tubotympanic CSOM patients in tertiary hospital, Purwokerto, Indonesia in 2016-2017.METHODS: Ear swab specimens were collected from patients with tubotympanic CSOM. S. aureus and P. aeruginosa were isolated and identified by culture, matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), and molecular tools. Antimicrobial susceptibility testing was performed using the disk diffusion method.RESULTS: Out of ear swabs from 34 patients with tubotympanic CSOM, P. aeruginosa and S. aureus were identified in 35%patients. No Methicillin-resistant S. aureus (MRSA) strain was found from the ear swabs of the patients with tubotympanic CSOM. Bacterial identification using the MALDI-TOF MS was concordantly with culture and molecular tools. All S. aureus isolates showed full susceptibility to cefoxitin and trimethoprim-sulphamethoxazole. Resistance to tetracycline was common with only 64% of S. aureus strains being susceptible. Meanwhile, all P. aeruginosa strains were susceptible to cefepime, cetazidime, meropenem, gentamicin, and tobramycin.CONCLUSION: S. aureus and P. aeruginosa are found in patients with tubotympanic CSOM and still susceptible to different antibiotic agents. MALDI-TOF MS demonstrate rapid, accurate and robust to detect S. aureus and P. aeruginosa.KEYWORDS: Staphylococcus aureus, Pseudomonas aeruginosa, chronic tubotympanic suppurative otitis media

Over a 1-year period, a diagnosis of suppurative otitis media was made in 21 infants less than 6 weeks of age, with symptomatology varying from mild rhinorrhea and cough to irritability and severe, protracted diarrhea. Only four infants presented with fever greater than 38°C. One-third of the patients had been born prematurely, 90% were bottle-fed, and only two had significant congenital malformations. Two-thirds of the babies with otitis of bacterial origin were male. Infants admitted to the study underwent diagnostic tympanoparacentesis, yielding purulent material and bacterial growth from all but three. The predominant organisms isolated were Escherichia coli, Staphylococcus aureus, and Klebsiella pneumoniae. In cases of treatment failure, reinfection was most common with Pseudomonas aeruginosa. On the basis of disc sensitivities, only 61% of the exudates from which bacteria were isolated proved amenable to ampicillin therapy alone. Bacteria cultured from nasopharyngeal swabs of the same infants showed a correlation with ear isolations in only 28% of the cases. When a 10-day course of therapy was carried out utilizing antibiotics to which the organism was sensitive, there was a 22% failure rate, suggesting the possible need for more prolonged therapy with a parenterally-administered agent plus ampicillin in the management of otitis media in the neonate and young infant.
