PMID: 2152070

We evaluated the usefulness of therapeutic drug monitoring (TDM) for gentamicin and the use of a two-point peak and trough pair concentration method to adjust its dose. Of the 194 patients included, initial concentrations were appropriate in only sixty nine. In the seventy one cases of dosage adjustments using this method, those attaining therapeutic levels increased overall from 38% to 67%. It is concluded that TDM for gentamicin with dosage adjustment using this simple pharmacokinetic approach is useful and adequate in monitoring for gentamicin therapy.

PMID: 6353185

A three and a half year old boy with shigellosis developed fulminant hepatic failure. The hepatic derangements rapidly improved over a period of two weeks after treatment of the shigellosis with parenteral gentamicin. We believe this is the first documented report of fulminant hepatic failure due to shigella sepsis.

Gentamicin administration via peritoneal dialysis fluid: the risk of ototoxicity

Gendeh BS, Said H, Gibb AG, Aziz NS, Zahir ZM

J Laryngol Otol, 1991 Dec;105(12):999-1001.

PMID: 1787382

In a prospective study on 47 patients, 16 mg of gentamicin per two litres dialysate was administered intraperitoneally at every cycle of intermittent peritoneal dialysis, carried out over the course of several days. Serum gentamicin sampling, pure tone audiometry and caloric tests were performed before and during the treatment. The gentamicin levels reached at the end of the thirtieth cycle were observed to be low. In view of this, the risk of acute ototoxicity was considered to be minimal. This was confirmed by the absence of clinical audiometric or vestibulometric evidence of toxicity.

Melioidosis presenting as prostatitis--a case report from Sabah

Kan SPK, Kay RWW

Trans R Soc Trop Med Hyg, 1978;72(5):522-4.

PMID: 725999 DOI: 10.1016/0035-9203(78)90175-X

Previous reports of melioidosis in Sabah are reviewed and a detailed account of a case, presenting as prostatitis, in a 40-year-old British male is given. The history suggested that the organism, Pseudomonas pseudomallei, was transmitted by a fly which entered the eye. Diagnosis was delayed and treatment presented some difficulty, the organism being relatively insensitive to amplicillin and gentamicin. Co-trimoxazole was the most effective, followed by minocycline. Cure was eventually achieved and after four years the patient was fit and normal, except for sterility.

Comparative evaluation of bioburden and sterility of indigenously prepared bone allograft with and without gentamicin

Makker K, Lamba AK, Faraz F, Tandon S, Sheikh Ab Hamid S, Aggarwal K, et al.

Cell Tissue Bank, 2019 Jun;20(2):243-253.

During bone allograft processing, despite stringent donor screening and use of aseptic techniques, microbial invasion may occur due to the porous nature of the graft and cause potentially fatal infections. The aim of the present study was to prepare bone allograft with and without gentamicin and to compare bioburden and sterility in the obtained grafts to evaluate the role of antibiotic in enhancing graft safety. Fifty samples of demineralized freeze-dried bone allograft were prepared from suitable donors according to international standards. Randomly selected 25 samples were placed in 8 mg gentamicin/gram bone solution for 1 h. Packaging and sealing was done to ensure no microbial ingress during transportation. 40 samples were selected for bioburden testing. Remaining 10 were subjected to 25 kGy gamma radiation and tested for sterility. Microbiological evaluation revealed no evidence of colony forming units in all the samples of both the groups (Bioburden = 0). Post-radiation sterility testing also revealed no bacterial colony in the tested samples from both the groups. Favorable results validate the processing protocol while comparable results in both groups indicate no additive benefit of gentamicin addition. Nil bioburden may be used in further studies to determine a lower radiation dose to achieve adequate sterility and minimize the disadvantages of radiation like collagen cross-linking and decreased osteoinductive capacity.

Fulltext Use of gentamicin impregnated POP discs for antibiotic pouch dressing

Lau CP, Chee EK, Thirumal M

Med J Malaysia, 2006 Dec;61 Suppl B:32-6.

PMID: 17600990

Antibiotic pouch technique is commonly used due to the high local antibiotic concentration and moist environment for wound healing. We used locally made gentamicin impregnated Plaster of Paris discs in treating wounds with exposed deep structures like tendons and bones. Out of 22 patients treated with this method, 19 completed treatment. Granulation tissue formed quickly and effectively covered the exposed structures. All wounds either healed by secondary intention or became suitable for split skin grafting. Gentamicin impregnated Plaster of Paris disc pouch dressing is safe, cost saving, and effective for management of deep open wounds.

A clinical and economic study of community-acquired pneumonia between single versus combination therapy

Hasali MA, Ibrahim MI, Sulaiman SA, Ahmad Z, Hasali JB

Pharm World Sci, 2005 Jun;27(3):249-53.

PMID: 16096896

BACKGROUND: Pneumonia is one of the leading causes of morbidity and mortality among children in many developing countries. It is reported that 12.9 million children under 5 years of age died world-wide in 1990 and one-third of these deaths or 4.3 million annually were attributed to acute respiratory infection with pneumonia.

OBJECTIVES: On this basis, a study was conducted in a district hospital to study the therapy outcomes of antibiotic regimens used in pediatric community-acquired pneumonia (CAP) management and to conduct a cost-effectiveness analysis (CE) between IV ampicillin versus combination therapy of IV ampicillin and IV gentamicin.

METHOD: A prospective, randomized, controlled, single blind study was conducted in a pediatric ward in a 80-bed district hospital. Pediatric patients diagnosed with CAP aged 2 months to 5 years old were randomly and equally divided into two treatment arms: ampicillin versus ampicillin plus gentamicin. The dose of IV ampicillin used in this study was 100 mg/kg/day divided every 6 h and 5 mg/kg of IV gentamicin as a single daily dose. Both clinical and economic evaluations were carried out to compare both treatment arms.

RESULTS: With the inclusion and exclusion criteria, only 40 patients diagnosed with CAP were included in the study. The results showed that the two treatment arms were significantly different (P < 0.05) in terms of duration of patients on ampicillin, number of days of hospitalization and time to switch to oral therapy. A significant difference was noted between the two treatment modalities in terms of effectiveness and cost (P < 0.05).

CONCLUSION: Overall, the endpoint of this study showed that the total cost per patient of ampicillin-treated group is cheaper than the total cost with the combination therapy (ampicillin plus gentamicin) and reduced unnecessary exposure to adverse effects or toxicities. Besides that, addition of gentamicin in the treatment modalities will only increase the cost of treatment without introducing any changes in the treatment outcome.

Gentamicin ototoxicity in continuous ambulatory peritoneal dialysis

Gendeh BS, Said H, Gibb AG, Aziz NS, Kong N, Zahir ZM

J Laryngol Otol, 1993 Aug;107(8):681-5.

PMID: 8409715 DOI: 10.1017/s0022215100124132

A prospective study was undertaken of 10 chronic renal failure patients on Continuous Ambulatory Peritoneal Dialysis (CAPD) complicated by repeated bouts of peritonitis treated with gentamicin. Each 10-day treatment course consisted of a 120 mg loading dose, followed by 16 mg in 21 of peritoneal dialysate, given four times a day. Serum gentamicin analysed by enzyme immunoassay showed a mean level of 5.2 micrograms/ml, (range 3.7 to 6.6 mg/ml) four hours after the loading dose. Similar levels, well within the therapeutic range, were maintained on the 3rd, 5th, 7th and 9th days of intraperitoneal gentamicin therapy, suggesting no accumulation of gentamicin in the serum. Pure tone audiometry, electronystagmography and clinical assessment were performed during each course of treatment. Although no evidence of ototoxicity was found during the first two courses of gentamicin, but disequilibrium and bobbing oscillopsia were present during the third and fourth courses of gentamicin. These findings could be explained by cumulative injury to the vestibular apparatus caused by repeated therapeutic insults.

Providing guidelines and education is not enough: an audit of gentamicin use at The Royal Melbourne Hospital

Leong CL, Buising K, Richards M, Robertson M, Street A

Intern Med J, 2006 Jan;36(1):37-42.

PMID: 16409311

BACKGROUND: Aminoglycoside antibiotics are commonly prescribed for the treatment of Gram-negative infections. Appropriate dosing and therapeutic monitoring of aminoglycosides are important because these agents have a narrow therapeutic index.
AIM: To audit gentamicin use at our hospital, focusing on selection of the initial dose and therapeutic monitoring practices, and to compare the results against recommendations in the existing hospital aminoglycoside guidelines, which had recently been promoted to doctors.
METHODS: This audit included all inpatients receiving gentamicin at The Royal Melbourne Hospital from 1 February to 12 March 2004. The principal researcher checked the drug charts of all inpatients to identify those receiving gentamicin and collected data from the medical records and the pathology database. Doses were considered 'concordant' if the dose given was within the recommended dosing range +/-20 mg.
RESULTS: A total of 132 courses of gentamicin was included in the study. Gentamicin was prescribed for prophylaxis in 31.1% of courses. Thirty-six per cent of patients prescribed gentamicin were more than 65 years of age. Eighty-two per cent of the gentamicin used therapeutically was given as a single daily dose. Sixty-six per cent of gentamicin initial dosing was not in accordance with existing hospital guidelines. Seventy-seven per cent of gentamicin courses requiring therapeutic drug monitoring received such monitoring; however, in only 8.8% of these was the monitoring conducted according to guidelines.
CONCLUSION: Aminoglycoside prescribing practices at our hospital are suboptimal, despite ready access to prescribing guidelines. Provision of a guideline and education sessions with doctors do not necessarily lead to widespread adoption of recommended practices. We suggest that changes to hospital systems related to prescribing and monitoring of aminoglycosides are required.

Fulltext Paediatric oropharyngeal tularaemia requiring surgical intervention

Nemmour A, Bakri A, Fischer CA, Brand Y

BMJ Case Rep, 2019 Sep 06;12(9).

PMID: 31494583 DOI: 10.1136/bcr-2019-229754

Tularaemia is a rare infectious disease endemic in most European countries caused by the bacterium Francisella tularensis 1 Patients often show acute non-specific symptoms, which causes a delay in diagnosis and proper treatment, potentially resulting in significant morbidities such as deep neck abscess, meningitis, endocarditis and septic shock. The authors present a case of a 5-year old boy with a 4-day history of fever, sore throat and painful cervical lymphadenopathy, whose clinical progression worsened despite being treated with recommended antibiotics as per WHO guidelines once the diagnosis of Tularaemia was confirmed by serologic tests. He developed a parapharyngeal abscess and a persistent left necrotic cervical lymph node, which both were surgically drained and excised, respectively, and an extended course of antibiotic was given. Subsequently, the patient fully recovered from the illness and the follow-up was negative for relapse.
