Clinicomicrobiological profile, visual outcome and mortality of culture-proven endogenous endophthalmitis in Taiwan.

This is a retrospective study in consecutive cases with cultured-proven endogenous endophthalmitis (EE) treated at the largest tertiary medical center in middle Taiwan in the past 10 years. 83 eyes of 70 patients were enrolled. The mean interval between systemic diseases to the diagnosis of EE was 8.84 ± 6.94 days. The mean initial visual acuity (VA) in the logarithm of minimal angle of resolution (logMAR) was 1.63 ± 0.87. Type 2 diabetes mellitus was the most common predisposing medical illness (N = 53, 63.86%). The most common infectious sources were intra-abdominal abscess (N = 36, 43.37%), and the second most reason was urinary tract infection. The causative pathogen was Gram-negative predominant (N = 64, 77.11%). After aggressive treatment, 34.94% of eyes regain useful vision, and only six eyes underwent enucleation or evisceration. The binary multivariate logistic regression model revealed that female gender (95% CI 1.002-19.036, p = 0.05, OR 4.37), initial VA logMAR (95% CI 0.089-0.550, p = 0.01, OR 0.22), and more intravitreal injections (95% CI 0.368-0.927, p = 0.023, OR 0.58) were independent risk factors influencing final outcomes. Based on the results mentioned above, early diagnosis is recommended to gain better outcomes. The mean interval between systemic diseases to the diagnosis of EE was 8.84 ± 6.94 days in our sample population, clinicians should maintain a higher index of suspicion during this period when encountering patients with bacteremia or fungemia.

Epidemiology and Mortality-Related Prognostic Factors in Endophthalmitis.

Purpose: Endophthalmitis describes any intraocular inflammation that involves both the posterior and anterior segments and is divided into endogenous and exogenous types according to its pathogenesis. The incidence of endophthalmitis and its risk factors have been extensively evaluated. However, few studies have explored the mortality rate in patients diagnosed with endophthalmitis. Methods: We obtained data entered into the National Health Insurance Research Database (NHIRD) from 2000 to 2013. The data collected included all discharge diagnoses of endophthalmitis in inpatients. Baseline characteristics, comorbidities, and prognostic factors were evaluated. Results: This study identified 7764 patients who were diagnosed with endophthalmitis in Taiwan from 2000 to 2013. The mortality rate was 0.97% (75/7764), and the mean age was 63.57 ± 15.72 years. Epidemiological characteristics were compared as "with or without" for different systemic comorbidities, and the results indicated that the adjusted odds ratio (AOR) was significantly higher in cases comorbid with renal disease (AOR 2.864, P = 0.001), septicemia (AOR 8.886, P < 0.001), pneumonia (AOR 2.072, P = 0.030), and tumors (AOR 7.437, P < 0.001). However, comorbidity with diabetes mellitus (DM) lowered the AOR by 0.500-fold (P = 0.026). There was no significant difference in ORs between patients comorbid with hypertension, depression, anxiety, hyperlipidemia, thyrotoxicosis, liver disease, or injury (all P > 0.05). Conclusions: Among inpatients with endophthalmitis, predictors of mortality include renal disease, septicemia, pneumonia, neoplasia, a greater burden of comorbidity (especially catastrophic illness), longer hospital stays (more than 11 days), and higher medical costs. Interestingly, DM decreased the OR for inpatient mortality.

Mortality after endophthalmitis following contemporary phacoemulsification cataract surgery.

IMPORTANCE: To determine if endophthalmitis following cataract surgery is linked to increased mortality. BACKGROUND: Increased mortality has been linked to patients with cataract and cataract surgery. We tested the hypothesis that post-cataract endophthalmitis has a greater risk of death than pseudophakes who do not develop this complication. DESIGN: Case-control study conducted in a tertiary public hospital. PARTICIPANTS: The study group comprised 50 consecutive patients with post-cataract endophthalmitis, and these were matched with selected controls. METHODS: Patients with endophthalmitis following cataract surgery were identified from a prospective electronic surgical database. Subsequently, it was determined if the patient was deceased at the time of sequestration (September 2015), and the date of death was recorded. A previously described population who had undergone cataract surgery in the same facility was selected as a control group, and the population was case-matched in terms age, gender, presence or absence of diabetes and/or hypertension. MAIN OUTCOME MEASURES: The median survival rates were determined for the control group and the patients with post-cataract endophthalmitis. RESULTS: Fifty patients were identified as undergoing endophthalmitis post-cataract surgery, and 48 (n = 48) met inclusion criteria (mean age 72 years ±12 SD with 30:18 F:M); 17% were diabetic, and 50% had systemic hypertension. No statistically significant difference in median survival between the study and control cases was identified (100 months (95% confidence interval 86-114) vs. 106 months (95% confidence interval 66-146), respectively, P = 0.756). CONCLUSIONS AND RELEVANCE: Post-cataract endophthalmitis was not associated with an increased rate of mortality in this study.

Incidence and Risk Factors of Ocular Infection Caused by Staphylococcus aureus Bacteremia.

Staphylococcus aureusbacteremia (SAB) often leads to ocular infections, including endophthalmitis and chorioretinitis. However, the incidence, risk factors, and outcomes of ocular infections complicated by SAB are largely unknown. We retrospectively analyzed the incidence and risk factors of ocular involvement in a prospective cohort of patients with SAB at a tertiary-care hospital. Ophthalmologists reviewed the fundoscopic findings and classified the ocular infections as endophthalmitis or chorioretinitis. During the 5-year study period, 1,109 patients had SAB, and data for 612 (55%) who underwent ophthalmic examinations within 14 days after SAB onset were analyzed. Of those 612 patients, 56 (9% [95% confidence interval [CI], 7 to 12%]) had ocular involvement, including 15 (2.5%) with endophthalmitis and 41 (6.7%) with chorioretinitis. In a multivariate analysis, infective endocarditis (adjusted odds ratio [aOR], 5.74 [95% CI, 2.25 to 14.64]) and metastatic infection (aOR, 2.38 [95% CI, 1.29 to 4.39]) were independent risk factors for ocular involvement. Of the 47 patients with ocular involvement who could communicate, only 17 (36%) had visual disturbances. Two-thirds of the patients with endophthalmitis (10/15 patients) were treated with intravitreal antibiotics combined with parenteral antibiotics, whereas all of the patients with chorioretinitis were treated only with systemic antibiotics. No patients became blind. Among 42 patients for whom follow-up assessments were available, the ocular lesions improved in 29 (69%) but remained the same in the others. Ocular involvement was independently associated with death within 30 days after SAB onset. Ocular involvement is not uncommon among patients with SAB. Routine ophthalmic examinations should be considered for patients with infective endocarditis or metastatic infections caused by SAB.

Neonatal endogenous endophthalmitis: a report of six cases.

Endogenous endophthalmitis is a rare but potentially blinding complication of neonatal sepsis. Early diagnosis and aggressive treatment are essential to avoid vision loss. Therapeutic options include systemic and intravitreal antibiotics, as well as vitrectomy in selected cases. We report a series of 6 premature very low birth weight neonates who developed endogenous endophthalmitis in our NICU over the past 3 years. Endophthalmitis was part of early-onset sepsis in 2 newborns, both of whom died, and late-onset sepsis in 4 newborns, of which 1 infant died. None of the neonates had any history of previous trauma or intervention to the eye. Maternal screening for congenital infections, including HIV, was negative in all. Causative organisms included Klebsiella pneumoniae (2 cases), Pseudomonas aeruginosa (2 cases), Methicillin-resistant Staphylococcus aureus (1 case), and Candida albicans (1 case). All bacterial isolates showed resistance to first-line antibiotics. Of the 3 survivors, 2 infants had normal vision in the affected eye, and 1 developed phthisis bulbi after corneal perforation and required enucleation. This report draws attention to the emergence of endophthalmitis as a complication of neonatal sepsis in places where, although survival of very low birth weight newborns has increased significantly due to improved care, the burden of infection continues to be high. We emphasize the importance of daily examination of eyes as a part of routine clinical care in septic newborns for early diagnosis of endophthalmitis and prompt intervention in consultation with an ophthalmologist to optimize the outcome.

Long-term mortality of patients with septic ocular or central nervous system complications from pyogenic liver abscess: a population-based study.

BACKGROUND: Taiwan is endemic for pyogenic liver abscess (PLA). Septic ocular or central nervous system (CNS) complications derived from PLA can result in catastrophic disability. We investigated the epidemiology and long-term prognosis of PLA patients with septic ocular or CNS complications over an 8-year period. METHODOLOGY/PRINCIPAL FINDINGS: We extracted 21,307 patients with newly diagnosed PLA from a nationwide health registry in Taiwan between 2000 and 2007. The frequency of and risk factors for PLA with septic ocular or CNS complications were determined. The 2-year survival of these patients was compared between those with and without septic ocular or CNS complications. Septic ocular or CNS complications accounted for 2.1% of all PLA patients. Age and the Charlson comorbidity index were significantly lower in PLA patients with ocular or CNS complications than those without. Diabetes and age <65 years were independent predictors of septic ocular or CNS complications. The 2-year mortality of patients with septic ocular or CNS complications was similar to those without complications (24.8% vs. 27.5%, p = 0.502). However, among patients <65 years old and a Charlson index ≤ 1, the 2-year mortality was significantly higher in those with than without complications (18.6% vs. 11.8%, p = 0.001). CONCLUSIONS/SIGNIFICANCE: Physicians should recognize that catastrophic disability due to ocular or neurological complications from PLA could lead to a poor long-term prognosis, and should follow-up these patients more closely.

Overall and cancer related mortality among patients with ocular inflammation treated with immunosuppressive drugs: retrospective cohort study.

CONTEXT: Whether immunosuppressive treatment adversely affects survival is unclear. OBJECTIVE: To assess whether immunosuppressive drugs increase mortality. DESIGN: Retrospective cohort study evaluating overall and cancer mortality in relation to immunosuppressive drug exposure among patients with ocular inflammatory diseases. Demographic, clinical, and treatment data derived from medical records, and mortality results from United States National Death Index linkage. The cohort's mortality risk was compared with US vital statistics using standardised mortality ratios. Overall and cancer mortality in relation to use or non-use of immunosuppressive drugs within the cohort was studied with survival analysis. SETTING: Five tertiary ocular inflammation clinics. Patients 7957 US residents with non-infectious ocular inflammation, 2340 of whom received immunosuppressive drugs during follow up. Exposures Use of antimetabolites, T cell inhibitors, alkylating agents, and tumour necrosis factor inhibitors. MAIN OUTCOME MEASURES: Overall mortality, cancer mortality. RESULTS: Over 66 802 person years (17 316 after exposure to immunosuppressive drugs), 936 patients died (1.4/100 person years), 230 (24.6%) from cancer. For patients unexposed to immunosuppressive treatment, risks of death overall (standardised mortality ratio 1.02, 95% confidence interval [CI] 0.94 to 1.11) and from cancer (1.10, 0.93 to 1.29) were similar to those of the US population. Patients who used azathioprine, methotrexate, mycophenolate mofetil, ciclosporin, systemic corticosteroids, or dapsone had overall and cancer mortality similar to that of patients who never took immunosuppressive drugs. In patients who used cyclophosphamide, overall mortality was not increased and cancer mortality was non-significantly increased. Tumour necrosis factor inhibitors were associated with increased overall (adjusted hazard ratio [HR] 1.99, 95% CI 1.00 to 3.98) and cancer mortality (adjusted HR 3.83, 1.13 to 13.01). CONCLUSIONS: Most commonly used immunosuppressive drugs do not seem to increase overall or cancer mortality. Our results suggesting that tumour necrosis factor inhibitors might increase mortality are less robust than the other findings; additional evidence is needed.

Fungal endophthalmitis in a tertiary care cancer center: a review of 23 cases.

Few data exist on the etiology, presentation, prognosis, and management of fungal endophthalmitis (FE) in cancer patients. FE cases were identified by reviewing the ophthalmology reports and microbiology cultures of patients at The University of Texas M. D. Anderson Cancer Center. We retrospectively reviewed the medical records and obtained information related to malignancy, fungal infection and its management, visual outcome, and mortality. We compared FE caused by Candida spp. (CE) to FE caused by molds (ME). Of the 102 cancer patients with a fungal infection for whom an ophthalmology consult was requested, 23 met the criteria for definite (N = 6) or probable (N = 17) FE (8 with CE, 15 with ME). All of the patients with ME had hematologic malignancies, whereas half of the patients with CE had solid tumor (P = .008). Only patients with CE had a history of surgery within 30 days of FE diagnosis (38%, P = .03). Fungal pneumonia [17 (74%)] and disseminated infection [14, (61%)] were common. The most common presenting symptoms were decreased vision [16 (70%)] and ocular pain [14 (61%)]. All treated patients received systemic antifungals (combination therapy in 72% of the cases). Seven patients (30%) underwent vitrectomy. Only one patient received intraocular injection of amphotericin B along with systemic antifungals. Four-week mortality was high [13 (57%)], especially in ME (73%, P = .04). Among the eight surviving patients where visual acuity could be assessed, visual outcome improved or remained stable in five (63%). FE in cancer patients occurs in the setting of severe, frequently disseminated opportunistic mycoses, is caused predominantly by hyalohyphomycetes, and is a marker for high 4-week mortality.

[Endogenous bacterial endophthalmitis: a retrospective study on 22 consecutive cases]. / Endogene bakterielle Endophthalmitis: eine retrospektive Studie an 22 konsekutiven Fällen.

BACKGROUND: Cases of endogenous bacterial endophthalmitis were analysed regarding predisposing factors, timing of diagnosis, sources of infection, causative organisms, and visual outcome. The value of an immediate vitrectomy compared to exclusively injected intravitreal antibiotics was evaluated reviewing the literature. METHODS: Records of 22 consecutive cases of the last 9 years with endogenous bacterial endophthalmitis were reviewed. The identified source of infection was treated with systemic antibiotics. All affected eyes were treated with intraocular injection of antibiotics, whenever possible combined with vitrectomy. RESULTS: 90% of the patients had severe predisposing diseases, primarily diabetes mellitus combined with renal insufficiency and urinary tract infection (70%). Diagnoses were made 3.5 days after beginning of symptoms. An average of 75% of the patients had gram-positive and 25% gram-negative bacteria as causative organisms. Most common gram-positive bacteria were Staphylococcus aureus and S. epidermidis. In 73% of all eyes vitrectomy was used as primary treatment. In 57% of the cases the visual outcome was light perception or better (excluding primary enucleations and deceased patients). 7% of the eyes had no light perception, 36% underwent secondary enucleation. Especially in cases of early diagnoses (less than or equal to 2 days) therapy was successful (60% of the patients); in contrast to delayed diagnoses (33%). The literature review suggests that immediate vitrectomy is superior to exclusive intravitreal injection of antibiotics concerning bulb conservation and remaining function. CONCLUSIONS: Immediate diagnosis and therapy are crucial for a positive outcome in this ophthalmological emergency. Immediate pars plana vitrectomy with intraocular antibiotic instillation seems to improve the prognosis of the affected eyes.

[Status of fluconazole in the therapy of endogenous Candida endophthalmitis]. / Der Stellenwert von Fluconazol in der Therapie der endogenen Candida-Endophthalmitis.

During the clinical course of invasive candidosis, endogenous Candida endophthalmitis (ECE) is associated with a higher mortality. In patients with candidemia, an ECE-incidence of 28 to 37% was reported. In i.v.-drug users, the incidence of Candida infections was 21%. Besides surgical procedures including vitrectomy and enucleation, early initiation of systemic antifungal therapy is decisive for the outcome. The clinical use of fluconazole in ECE is documented in 96 patients and in a minimum of 108 eyes. The mean duration of therapy was 6-8 weeks (maximum duration: lifelong) with an average dosage of 200-400 mg/d (maximum dosage: 800 mg/d and 14 mg/kg BW, resp.). The results reported in the literature show a good clinical efficacy of fluconazole in ECE: 90% response rate (19/21) in patients with/without concomitant vitrectomy and with/without concomitant use of other antifungals, complete disappearance of all eye lesions in 94% (15/16) non-neutropenic patients with candidemia and in 86% (6/7) ECE-patients addicted to heroin. With respect to these favorable results, fluconazole plays an important role in the standard therapy of ECE.

Mortality of hospitalized patients with Candida endophthalmitis.

BACKGROUND: Candida is becoming an important nosocomial pathogen as the incidence of hospital-acquired candidemia is rising. Candida endophthalmitis is a good indicator of systemic candidiasis in hospitalized patients. METHODS: Thirteen (17%) of 76 ophthalmologic consultations for Candida endophthalmitis in our institution had positive findings during a 12-month period. We studied these 13 patients with Candida endophthalmitis to evaluate their outcomes. RESULTS: All 13 patients were admitted to a large tertiary care hospital, and 10 (77%) were in an intensive care unit. The overall mortality was 77% for all patients and 80% for the intensive care patients. This mortality was higher than the overall mortality for all patients in the surgical intensive care unit in our institution (17%), as well as the mortality for our patients with candidemia in the surgical intensive care unit (61%). CONCLUSIONS: The strikingly high mortality in our group of patients with Candida endophthalmitis reflects the fact that they are a seriously ill group with multiple risk factors for Candida infection. This information suggests that the presence of Candida endophthalmitis is a good indicator of high mortality in seriously ill patients in intensive care units.
