Calisir K, Mohamed HM, Yussuf AA. Multi-drug resistant Klebsiella-induced corneal ulcer following pterygium surgery: a case report. BMC Ophthalmol 2023; 23:175. [PMID: 37095479 PMCID: PMC10124041 DOI: 10.1186/s12886-023-02928-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Accepted: 04/19/2023] [Indexed: 04/26/2023] Open
Abstract
BACKGROUND Management of pterygium is dependent on the grading of pterygium and its clinical presentation (inflamed or quiescent), and surgical excision is the final choice of treatment for the pterygium extending beyond the limbus. Infectious keratitis is one of the most commonly reported complications in recent years. To the best of our knowledge, Klebsiella keratitis after pterygium surgery has not been described in the current literature. Here, we report a patient with corneal ulcer formation following pterygium surgical excision. CASE PRESENTATION A 62-year-old woman presented with complaints of pain, blurred vision, photophobia and redness in her left eye for a month. She had a history of pterygium surgical excision two months ago. Slit-lamp examination showed conjunctival congestion, a central whitish corneal ulcer with a central epithelial defect, and hypopyon. Corneal scraped sample revealed multidrug resistant (MDR) Klebsiella pneumonia and the strain was found to be sensitive to cefoxitin and ciprofloxacin. Intracameral cefuroxime (1 mg/0.1 mL) injection, fortified cefuroxime ophthalmic suspension (50 mg/mL) and moxifloxacin ophthalmic suspension (0.5%) were successfully administered to control the infection. Since residual central stromal opacification remained persistent, final visual acuity did not improve beyond finger counting at two meters. CONCLUSIONS Klebsiella keratitis is a rare and sight-threatening complication following pterygium excision. This report emphasizes the importance of close follow-up examination following pterygium surgeries.

Abstract
PURPOSE To study predisposing factors, clinical presentation and management strategies for Klebsiella keratitis. METHODS A retrospective case review was performed on clinical records of culture-proven Klebsiella keratitis cases in a tertiary referral center over an 8-year period (from 2012 to 2020). RESULTS Thirty eight episodes of culture-proven Klebsiella keratitis were identified in 37 patients. The mean age of the patients was 62.9 years (range, 24-101). Multiple predisposing factors were identified in 33 eyes including history of previous keratoplasty (n = 11) history of ocular trauma (n = 7), preexisting ocular surface disease (n = 7) and diabetes (n = 6). Corrected distance visual acuity (CDVA) at presentation was light perception (LP) in 16 patients, hand motion (HM) in 12, counting fingers (CF) at 50 cm in 5, CF at 1 m in 1, CF at 2 m in 2. One patient had a CDVA of 3/10. On initial examination Hypopyon was detected in 21 eyes. Descemet's membrane folds were present in 1 eye. Corneal thinning was identified in 20 eyes and perforation occurred in 4 patients. Corneal ulcer progressed to endophthalmitis in one patient. Microbiologic sensitivity testing showed that 89.5% isolates were sensitive to amikacin (34/38),88.9%sensitive to ceftazidime (32/36),94.4% were sensitive to gentamicin (34/36),97.2% sensitive to ciprofloxacin (35/36), and 100% to levofloxacin (26/26).Ultimately, one or more surgical procedures was needed in 21 patients. CONCLUSION Previous keratoplasty, history of ocular trauma, ocular surface disease and systemic disease such as diabetes are major risk factors for Klebsiella keratitis. In most of the patients, surgical and tectonic procedures were necessary to control the infection.

Abstract
Bacterial keratitis continues to be one of the leading causes of corneal blindness in the developed as well as the developing world, despite swift progress since the dawn of the "anti-biotic era". Although, we are expeditiously developing our understanding about the different causative organisms and associated pathology leading to keratitis, extensive gaps in knowledge continue to dampen the efforts for early and accurate diagnosis, and management in these patients, resulting in poor clinical outcomes. The ability of the causative bacteria to subdue the therapeutic challenge stems from their large genome encoding complex regulatory networks, variety of unique virulence factors, and rapid secretion of tissue damaging proteases and toxins. In this review article, we have provided an overview of the established classical diagnostic techniques and therapeutics for keratitis caused by various bacteria. We have extensively reported our recent in-roads through novel tools for accurate diagnosis of mono- and poly-bacterial corneal infections. Furthermore, we outlined the recent progress by our group and others in understanding the sub-cellular genomic changes that lead to antibiotic resistance in these organisms. Finally, we discussed in detail, the novel therapies and drug delivery systems in development for the efficacious management of bacterial keratitis.

Abstract
Acute interface infectious keratitis (AIIK) is a rare and devastating complication following lamellar keratoplasty. Here, we report a case of AIIK following deep anterior lamellar keratoplasty (DALK) caused by double gram-negative bacilli and required urgent therapeutic penetrating keratoplasty (TPK). Microbiology revealed co-infection with Klebsiella and E. Coli sensitive only to colistin. Donor rim culture also grew Klebsiella. TPK was successful in controlling the infection and the patient responded to topical fortified amikacin and ciprofloxacin. Since optical quality tissue was used, the patient regained 20/40 vision postoperatively. This report highlights that immediate TPK and intense antimicrobial therapy can salvage these eyes with good visual outcome.

Abstract
With the growing popularity of lamellar keratoplasty for selective replacement of diseased corneal tissue, it is important to understand the risk of developing an infection after the procedure. Although lesser than that postpenetrating keratoplasty, the reports on post lamellar keratoplasty infectious keratitis are not negligible. Trends of acute infections arising within 2 months of surgery are a subject of interest. Most of these infections are reported post Descemet's stripping endothelial keratoplasty with a preponderance of Candida species. A donor to host transmission of infection is not uncommon. Among the Candida cases, about 80% seem to occur due to a donor to host transmission. Infections presenting as or progressing to endophthalmitis lead to a poor visual outcome. Strict aseptic measures and protocols during corneal tissue harvesting, tissue processing, tissue storage and surgery are essential to prevent occurrence of these infections. After the infection has occurred, determining the aetiology and drug susceptibility through microbiological testing is vital. This helps to guide treatment protocols and hence determines final outcome of these cases. Most cases require some form of surgical management for resolution of infection, most often a graft removal and therapeutic keratoplasty. Secondary surgical interventions are performed to restore graft clarity and achieve a good final visual outcome.

Abstract
Infectious keratitis after lamellar keratoplasty is a potentially devastating complication that may severely limit the visual and anatomical outcomes. The deep-seated location of the infiltrates, sequestration of the pathogenic microorganisms and limited penetration of the currently available antimicrobial agents often results in delayed diagnosis that may jeopardize the management in these cases. Fungal keratitis is more common as compared with bacterial or viral keratitis and classically presents as white interface infiltrates that may not be associated with significant inflammation. Confocal microscopy may help to establish a rapid diagnosis in such cases, and anterior segment optical coherence tomography may be used to determine the extent of infection and monitor its progression. Conservative measures such as topical antimicrobials and interface irrigation with antimicrobial agents may be done. Surgical intervention in the form of partial excision/removal of the graft in endothelial keratoplasty or a full-thickness keratoplasty is often required for the effective management of deep-seated infections. Timely diagnosis and intervention may result in complete resolution of infection in both anterior lamellar and endothelial keratoplasty. Infections after anterior lamellar keratoplasty have a fair prognosis, and a clear graft with functional visual acuity may be achieved in most cases. By contrast, infections after endothelial keratoplasty have a guarded prognosis, and the presence of concomitant endophthalmitis may further complicate the graft survival and visual outcomes.

Abstract
A healthy lady of 42 years underwent deep anterior lamellar keratoplasty for granular dystrophy. The very next day, it was complicated by development of infectious keratitis. The organism was identified as multidrug resistant Klebsiella pneumoniae. Donor corneal button may be implicated in the transmission of infection in an otherwise uneventful surgery and follow-up. Nosocomial infections are usually severe, rapidly progressive and difficult to treat. Finally, the lady had to undergo therapeutic penetrating keratoplasty for complete resolution of infection.

Abstract
OBJECTIVES Our objective was to evaluate the serologic positivity of cornea donors and microbiologic positivity of cornea storage media at the Ege University Tissue and Cornea Bank, Izmir, Turkey. MATERIALS AND METHODS We retrospectively investigated the serologic blood sample and microbiological culture media analysis results of all cornea donors at Ege University Tissue and Cornea Bank between 2007 and 2015 with reference to age, sex, and cause of death of each donor. RESULTS Mean age of the 955 deceased donors was 43.19 ± 15.89 years (range, 2-65 y). The mean postmortem time to blood sample removal and excision of the cornea tissue was 8.4 hours (range, 4-12 h). Serologic analyses showed that 855 donors (89.5%) were seronegative. The remaining donors were seropositive for hepatitis B (54 donors; 5.7%), human immunodeficiency (27 donors; 2.8%), hepatitis C (14 donors; 1.5%), and syphilis (5 donors; 0.5%) virus infections. Microbiologic analyses of the storage media were negative, with no microorganisms shown in 855 samples (89.5%). Candida species (32 donors; 3.4%), Escherichia coli (14 donors; 1.5%), Pseudomonas aeruginosa (11 donors; 1.2%), methicillin-resistant Staphylococcus aureus (11 donors; 1.2%), Enterobacter species (11 donors; 1.2%), Klebsiella pneumoniae (7 donors; 0.7%), Acinetobacter baumannii (6 donors; 0.6%), Proteus species (5 donors; 0.5%), and Corynebacterium species (3 donors; 0.3%) were the detected microorganisms in the infected storage media. CONCLUSIONS False-positive serologic results among cornea donors were high. The incidence of false-positive results might be decreased by earlier blood removal from deceased donors and testing of all potential donors in intensive care units. Although rare, endophthalmitis after keratoplasty might be a devastating problem. In addition to serologic testing, microbiologic analyses of cornea storage media before transplant may be an effective way to prevent postoperative infectious complications.
