ABSTRACT
The emergence of COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), triggered a global pandemic. Concurrently, reports of mucormycosis cases surged, particularly during the second wave in India. This study aims to investigate mortality factors in COVID-19-associated mucormycosis (CAM) cases, exploring clinical, demographic, and therapeutic variables across mostly Asian and partly African countries. A retrospective, cross-sectional analysis of CAM patients from 22 medical centers across eight countries was conducted, focusing on the first 3 months post-COVID-19 diagnosis. Data collected through the ID-IRI included demographics, comorbidities, treatments, and outcomes. A total of 162 CAM patients were included. The mean age was 54.29 ± 13.04 years, with 54% male. Diabetes mellitus (85%) was prevalent, and 91% had rhino-orbital-cerebral mucormycosis. Surgical debridement was performed in 84% of the cases. Mortality was 39%, with advanced age (hazard ratio [HR] = 1.06, [P < .001]), rituximab use (HR = 21.2, P = .05), and diabetic ketoacidosis (HR = 3.58, P = .009) identified as risk factors. The mortality risk increases by approximately 5.6% for each additional year of age. Surgical debridement based on organ involvement correlated with higher survival (HR = 8.81, P < .001). The utilization of rituximab and diabetic ketoacidosis, along with advancing age, has been associated with an increased risk of mortality in CAM patients. A combination of antifungal treatment and surgical intervention has demonstrated a substantial improvement in survival outcomes.
Over a third of patients who developed mucormycosis after COVID-19 died. Older people, those on specific immunosuppressive treatments, and those with diabetic ketoacidosis had a higher risk of death. However, undergoing surgery as part of treatment significantly improved survival.

OBJECTIVE: To investigate the impact of cumulative cisplatin dose on clinical outcomes in locally advanced cervical cancer patients undergoing definitive chemoradiotherapy. METHODS: A retrospective analysis was conducted on 654 patients with stage IB3-IVA disease treated with definitive chemoradiotherapy. Radiotherapy was applied as external beam pelvic with or without para-aortic radiotherapy and brachytherapy. Concomitant chemotherapy was in the form of weekly or 3 weekly cisplatin. Data on demographics, treatment protocols, cumulative cisplatin dose, adverse effects, and survival outcomes were collected. Statistical analyses, including univariate and multivariate Cox regression models, were used to assess factors influencing progression free survival and overall survival. RESULTS: The median cumulative cisplatin dose was 210 mg (range 40-320), and ≥200 mg in 503 (76.9%) patients. Median follow-up was 35 months (range 1-150). The 5 year progression free survival and overall survival rates were 66.9% and 77.1%, respectively. Multivariate analysis identified poor performance status, non-squamous cell histology, presence of lymph node metastases, and hemoglobin <10 g/dL before chemoradiotherapy as poor prognostic factors for both progression free survival and overall survival in the whole group. When stage III cases were evaluated separately, the cumulative cisplatin dose <200 mg was found to be a significant poor prognostic factor in overall survival (hazard ratio 1.79, 95% confidence interval 1.1 to 3.0, p=0.031). CONCLUSION: Our study showed that a cumulative cisplatin dose >200 mg, particularly in patients with lymph node metastases, significantly improved overall survival. Factors such as anemia, toxicity related challenges, and comorbidities were identified as critical considerations in treatment planning. These findings emphasize the balance between maximizing therapeutic efficacy and managing toxicity, guiding personalized treatment approaches for locally advanced cervical cancer.
ABSTRACT
BACKGROUND: During the COVID pandemic, research has shown an increase in candidemia cases following severe COVID infection and the identification of risk factors associated with candidemia. However, there is a lack of studies that specifically explore clinical outcomes and mortality rates related to candidemia after COVID infection. OBJECTIVES: The aim of this international study was to evaluate the clinical outcomes and identify factors influencing mortality in patients who developed candidemia during their COVID infection. PATIENTS/METHODS: This study included adult patients (18 years of age or older) admitted to the intensive care unit (ICU) and diagnosed with COVID-associated candidemia (CAC). The research was conducted through ID-IRI network and in collaboration with 34 medical centres across 18 countries retrospectively, spanning from the beginning of the COVID pandemic until December 2021. RESULTS: A total of 293 patients diagnosed with CAC were included. The median age of the patients was 67, and 63% of them were male. The most common Candida species detected was C. albicans. The crude 30-day mortality rate was recorded at 62.4%. The logistic regression analysis identified several factors significantly impacting mortality, including age (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.02-1.07, p < .0005), SOFA score (OR 1.307, 95% CI 1.17-1.45, p < .0005), invasive mechanical ventilation (OR 7.95, 95% CI 1.44-43.83, p < .017) and duration of mechanical ventilation (OR 0.98, 95% CI 0.96-0.99, p < .020). CONCLUSIONS: By recognising these prognostic factors, medical professionals can customise their treatment approaches to offer more targeted care, leading to improved patient outcomes and higher survival rates for individuals with COVID-associated candidemia.

BACKGROUND: We report the case of a patient with melanoma and liver failure with encephalopathy, successfully treated with nivolumab without major side effects and encouraging prolonged disease control. CASE PRESENTATION: In June 2022, metastatic lesions appeared in the liver associated with melanoma progression under treatment. Liver biopsy was non-diagnostic. The patient developed fever, abdominal distension, and jaundice. Liver function tests (LFTs) began to deteriorate. Hepatic encephalopathy developed in accordance with the worsening liver functions in the patient. Upper abdominal MRI with primovist showed multiple, progressive, metastatic lesions in the liver and mild to moderate dilatation of the intrahepatic biliary tract. Patient was evaluated as acute cholangitis associated with the compression of the biliary tract by progressive liver metastases. In December 2022, the patient was started antibiotherapy for cholangitis and Nivolumab (240â mg flat dose, every 2 weeks) therapy. After the first dose, both LFT and constitutional symptoms began to improve. Subsequently, LFTs almost completely returned to normal, clinical response was achieved. Multiple metastatic lesions in the liver regressed in the radiological evaluation performed at the third month of nivolumab treatment. With partial response, nivolumab treatment is continued. CONCLUSION: In this case is reported patient with hepatic encephalopathy due to an advanced refractory melanome successfully, and safely, treated with programed cell death-1 (PD-1) inhibitors. Clinical trials to explore the benefits of these immunotherapies in the hepatic failure population with advanced solid tumors should be supported.

PURPOSE: Sacral insufficiency fracture (SIF) is a commonly underdiagnosed etiology of back pain, especially in the geriatric and osteoporotic population. In this clinical study, we present our experience of 185 patients who were diagnosed with SIF and managed either with conservative or surgical treatment with a minimum 5-year follow-up. MATERIALS AND METHOD: Patients who were diagnosed with SIF, managed either conservatively or surgically, and had a minimum 5-year follow-up medical record were included in this study. CT scans and MR imaging including coronal STIR sequence were obtained from all. Bone densitometry (DEXA) was performed to detect accompanying osteopenia or osteoporosis. Patients were treated either conservatively or surgically. VAS and ODI scores were evaluated prior to the treatment and 1st day, 10th day, 3rd month, and 1st year postoperatively. RESULTS: The mean age of 185 patients was 69.2 and the mean follow-up period was 7.23 years (range: 5-11 years). 46 (24.9%) patients had a previous spinal or spinopelvic surgery and spinal instrumentation was implemented in 22(11.89%) of them. The time interval between the fusion surgery and the diagnosis of SIF was approximately 9.48 weeks. The fracture line could be detected with the MRI in 164 patients and with the CT in 177 patients. The fracture was bilateral in 120 (64.8%) patients. 102 patients were treated conservatively, and 83 received sacroplasty. VAS and ODI scores showed better improvement in pain and functionality in the surgical management group than in the conservative management group. CONCLUSION: SIF should be considered in the differential diagnosis of back and pelvic pain, especially in elderly and osteoporotic patients. MRI with coronal STIR imaging should be a standard protocol for patients with a risk of SIF. Our results show that sacroplasty provides better and faster pain relief and recovery than conservative management.

OBJECTIVES: To uncover clinical epidemiology, microbiological characteristics and outcome determinants of hospital-acquired bloodstream infections (HA-BSIs) in Turkish ICU patients. METHODS: The EUROBACT II was a prospective observational multicontinental cohort study. We performed a subanalysis of patients from 24 Turkish ICUs included in this study. Risk factors for mortality were identified using multivariable Cox frailty models. RESULTS: Of 547 patients, 58.7% were male with a median [IQR] age of 68 [55-78]. Most frequent sources of HA-BSIs were intravascular catheter [182, (33.3%)] and lower respiratory tract [175, (32.0%)]. Among isolated pathogens (nâ=â599), 67.1% were Gram-negative, 21.5% Gram-positive and 11.2% due to fungi. Carbapenem resistance was present in 90.4% of Acinetobacter spp., 53.1% of Klebsiella spp. and 48.8% of Pseudomonas spp. In monobacterial Gram-negative HA-BSIs (nâ=â329), SOFA score (aHR 1.20, 95% CI 1.14-1.27), carbapenem resistance (aHR 2.46, 95% CI 1.58-3.84), previous myocardial infarction (aHR 1.86, 95% CI 1.12-3.08), COVID-19 admission diagnosis (aHR 2.95, 95% CI 1.25-6.95) and not achieving source control (aHR 2.02, 95% CI 1.15-3.54) were associated with mortality. However, availability of clinical pharmacists (aHR 0.23, 95% CI 0.06-0.90) and source control (aHR 0.46, 95% CI 0.28-0.77) were associated with survival. In monobacterial Gram-positive HA-BSIs (nâ=â93), SOFA score (aHR 1.29, 95% CI 1.17-1.43) and age (aHR 1.05, 95% CI 1.03-1.08) were associated with mortality, whereas source control (aHR 0.41, 95% CI 0.20-0.87) was associated with survival. CONCLUSIONS: Considering high antimicrobial resistance rate, importance of source control and availability of clinical pharmacists, a multifaceted management programme should be adopted in Turkish ICUs.

BACKGROUND: Nivolumab is a monoclonal antibody that binds to the programmed death-1 (PD-1) receptor and blocks its interaction with PD-L1 and PD-L2. High response rates have been achieved with its use in the treatment of metastatic renal cell carcinoma (mRCC). We aimed to determine a relationship between 18-Fluoro-2-Deoxy-D-Glucose Positron Emission Tomography/Computed Tomography (18F-FDG-PET/CT) performed before nivolumab treatment and treatment-related survival. METHODS: Between 2014 and 2021, 32 patients who received nivolumab and had pre-treatment 18F-FDG-PET/CT evaluation were included in this retrospective study. The total SUV

OBJECTIVE: Skip corpectomy is a surgical technique that includes C4 and C6 corpectomies and fusion via autografts and a cervical plate and is frequently performed in patients with CSM and OPLL. This study presents long-term clinical and radiological outcomes of 48 patients who underwent skip corpectomy with 10-year follow-up. METHODS: 48 patients who were diagnosed with CSM or OPLL were included. All patients underwent spinal canal decompression and fusion via skip corpectomy. Clinical assessment was performed using the JOA scoring system. The radiological assessment was performed using plain anteroposterior, lateral, and flexion-extension cervical spine radiographs; cervical spine MR imaging; and cervical spine CT scans. The spinal canal size, spinal cord occupation ratio, cervical lordosis, and T2 signal changes were evaluated preoperatively, and postoperatively. RESULTS: The mean follow-up period was 14.6 years (13-20 years). Preoperatively, the JOA score was 11.06 ± 3.09. The mean cervical lordosis was 2.08°±11.74 and the average SCOR was 62.1 ± 14.22. There was a significant improvement in SCOR in the early postoperative period. The average cervical lordosis increased to 13.81 ± 2.51 in the 2nd month and minimal loss of cervical lordosis was observed on the 10th year in two patients. Fusion was achieved in all patients, regardless of the graft type. None of the patients had implant failure and graft or hardware-related complications at the 10th-year follow-up. CONCLUSION: Skip corpectomy provides efficient decompression of the spinal cord and provides adequate sagittal alignment and fusion in patients with CSM and OPLL. Long-term radiological and clinical outcomes of the technique are favorable.
ABSTRACT
BACKGROUND AND IMPORTANCE: Multiregional spinal stenosis [tandem spinal stenosis (TSS)] is not rare but operating on multiple regions at the same sitting is. Decompression of cervical and lumbar spine in the same session has a frequency of 5-25% all TSS cases, the most frequent one is TSS. Decompression in three different regions is so rare that there is only one case in the literature. We report the second. CLINICAL PRESENTATION: A 72-year-old man with pain in legs and arms, neurogenic claudication, progressive loss of balance, radiculopathy and myelopathy in lower and upper extremities whose cervical-thoracic and lumbar spinal stenosis were treated with decompressive surgery in the same session. Total time of surgery for three regions was 330 min. No complications were observed. The patient was mobilized on day 1 postoperative and was discharged from the hospital on day 3. By month 3, motor function had improved almost completely, and pyramidal findings have decreased. CONCLUSION: Multiregional spinal stenosis of three spinal regions at the same time is a rare case and these cases, surgery of three regions can be carried out in the same session respectively.

In our study, we aimed to evaluate the pathological response rates and side effect profile of adding pertuzumab to the treatment of HER2+ locally advanced, inflammatory, or early-stage breast cancer. This study was conducted by the Turkish Oncology Group (TOG) with data collected from 32 centers. Our study was multicentric, and a total of 364 patients were included. The median age of the patients was 49 years (18-85 years). Two hundred fifteen (60%) of the cases were hormone receptor/HER2+ positive(ER+ or PR+, or both), and 149 (40%) of them were HER2-rich (ER and PR negative). The number of complete responses was 124 (54%) in the docetaxel+trastuzumab+pertuzumab arm and 102 (45%) in the paclitaxel+trastuzumab+pertuzumab arm, and there was no difference between the groups in terms of complete response. In 226 (62%) patients with complete response, a significant correlation was found with DCIS, tumor focality, removed lymph node, and ER status P < 0.05. Anemia, nausea, vomiting, myalgia, alopecia, and mucosal inflammation were significantly higher in the docetaxel arm, P < 0.05. In our study, no statistical difference was found between the before-after echocardiography values. DCIS positivity in biopsy before neoadjuvant chemotherapy, tumor focality; the number of lymph nodes removed and ER status were found to be associated with pCR. In conclusion, we think that studies evaluating pCR-related clinicopathological variables and radiological imaging features will play a critical role in the development of nonsurgical treatment approaches.

INTRODUCTION: Immune checkpoint inhibitors (ICIs) are being commonly used to treat solid tumours such as renal cell carcinoma. Hypophysitis is an acute or chronic inflammation of the pituitary gland and nivolumab or pembrolizumab induced hypophysitis is markedly lower compared to ipilimumab. CASE REPORT: We present a novel case of a patient with mRCC who was diagnosed with nivolumab induced hypophysitis based on clinical suspicion due to his hormonal profile and a range of symptoms that he developed during nivolumab immunotherapy. MANAGEMENT AND OUTCOME: He was treated with high dose of hydrocortisone administered intravenously, subsequently changed to the oral route and physiologic dose. DISCUSSION: Nivolumab induced hypophysitis is a rare condition that usually presents with fewer symptoms. High degree of clinical suspicion and a multidisciplinary team required to diagnose and treat such cases.

PURPOSE: The aim of this study was to determine the effect of progressive relaxation exercises on the comfort level and sleep quality of patients undergoing lumbar disc herniation surgery. METHODS: The study was conducted between July 2015 and October 2016 in the neurosurgery clinic. The sample consisted of 96 patients (n = 56, experimental patients; n = 40 control patients) randomized into groups. The data was collected by using the personal information form, The Perianesthesia Comfort Questionnaire, The General Comfort Questionnaire and Visual Analog Sleep Scale. FINDINGS: In the postoperative General Comfort Scale that there was a statistically significant difference between the mean of the control group and experimental group on the final test (P < .05). When the Visual Analog Sleep Scale mean of the experimental and control group patients were compared between the groups, there was a statistically significant difference on the postoperative 2nd day and 3rd day (P < .05). CONCLUSION: This study supports previous work that progressive relaxation exercises are feasible and effective to improve patient comfort levels after lumbar disc surgery.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has quickly turned into a global pandemic with close to 5 million cases and more than 320,000 deaths. Cancer patients constitute a group that is expected to be at risk and poor prognosis in COVID pandemic. We aimed to investigate how cancer patients are affected by COVID-19 infection, its clinical course and the factors affecting mortality. METHODS: In our single-center retrospective study, we included cancer patients with laboratory confirmed COVID-19 in our hospital. Demographic, clinical, treatment, and laboratory data were obtained from electronic medical records. Logistic regression methods were used to investigate risk factors associated with in-hospital death. RESULTS: In the hospital, 4489 patients were hospitalized with COVID infection and 77 were cancer patients. The mean age of cancer patients was 61.9 ± 10.9 and 44 of them were male (62%). While the mortality rate in non-cancer patients was 1.51% (n = 68), this rate was significantly higher in cancer patients, 23.9% (n = 17). The stage of the disease, receiving chemotherapy in the last 30 days also lymphopenia, elevated troponin I, D-dimer, CRP, and CT findings were associated with severe disease and mortality. Severe lung involvement (OR = 22.9, p = 0.01) and lymphopenia (OR = 0.99, p = 0.04) are the most important factors influencing survival in logistic regression. CONCLUSIONS: The disease is more severe in cancer patients and mortality is significantly higher than non-cancer patients. These data show that it may be beneficial to develop dynamic prevention, early diagnosis and treatment strategies for this vulnerable group of patients who are affected by the infection so much.
ABSTRACT
INTRODUCTION: The response patterns of immune checkpoint inhibitors (ICIs) have been recognized to differ from those seen in standard cytotoxic and targeted therapy. Pseudoprogression and hyperprogression are new clinical phenomena specific to the field of immuno-oncology. In this study, we aimed to assess the frequency of hyperprogression and pseudoprogression in metastatic RCC and melanoma patients treated in our institution with the programmed cell death protein-1 inhibitor nivolumab. METHODS: The medical records of all metastatic melanoma and renal cell carcinoma patients that were treated with nivolumab (n = 54) in Bakirkoy Dr. Sadi Konuk Training and Research Hospital (Istanbul-Turkey), Medical Oncology Clinic between June 2017 and December 2019 were retrospectively analyzed. RESULTS: Hyperprogression and pseudoprogression rates were 12% and 9%, respectively and that is consistent with published data. DISCUSSION: Pseudoprogression and hyperprogression are new radiologic response patterns with immunotherapy agents. It is critical to be aware of these two phenomena in order to make the right decisions for patients.

INTRODUCTION: Among females, breast cancer is the most common type of cancer. Hormon receptor positive (HR+) subtype constitutes 75% of the diagnosed breast cancers. Combination of the cyclin D-cyclin-dependent kinase 4/6 (CDK4/6) inhibitor and endocrine therapy significantly improves overall survival and progression-free survival. Ribociclib is an oral CDK 4/6 inhibitor and some adverse effects are identified. According to MONALEESA 2-3-7 studies, no adverse effect (AE) were reported due to grade 3 or 4 acute kidney injury (AKI) that caused treatment discontinuation. CASE REPORT: We report a ribociclib-induced grade 3 AKI in an elderly woman who was treated for metastatic breast cancer. During first cycle of therapy, she was admitted to the oncology clinic with diagnosis of AKI.Management and outcome: Ribociclib treatment was discontinued and secondary causes of AKI were excluded. During the follow-up, kidney function values returned to the normal range spontaneously. Ribociclib treatment was re-initiated by reducing the dose (400 mg daily). Despite dose reduction; grade 3 AKI recurred when ribociclib was re-initiated and the drug was permanently discontinued. DISCUSSION: According to MONALEESA 2-3-7 studies; no AE were reported due to grade 3 or 4 AKI. Despite these studies, the FDA reported that 20% of patients with ribociclib + letrozole combination therapy may have any stage elevation of creatinine. Ribociclib induced creatinine elevations are generally mild (grade 1-2) and can be managed by dose reduction or close monitoring of creatinine levels. We report the first case of grade 3 AKI that caused treatment discontinuation following administration of ribociclib.

INTRODUCTION: Novel anti-cancer drugs such as targeted cancer therapies and immune check-point inhibitors (ICIs) have adverse events, especially concerning the skin. The aim of this study is to report an overview of the commonly consulted dermatological side effects of ICIs and targeted cancer therapies in clinical practice, along with their management. METHODS: In this single-center study, we evaluated consecutive oncological patients who were referred from the oncology outpatient clinic to the dermatology outpatient clinic due to skin side effects of ICIs and targeted therapies. All patients were examined and treated at the same day of referral by experienced dermatologists. Patient characteristics, clinical findings, diagnostic workups and treatments were retrieved from outpatient records. RESULTS: Sixty three patients were enrolled. Most common diagnoses were lung carcinoma, melanoma and colon carcinoma. Fifty patients (79%) were using targeted therapies while 13 (21%) were using ICIs. Xerosis was the most common side effect (44%), followed by acneiform rash, paronychia, eczema and pruritus. Majority of the side effects were grade 2 and 3. Psoriasis was a common side effect of ICIs. One patient had a newly developed dysplastic nevus on vemurafenib treatment. Oncological treatment was not withheld in any of the patients. CONCLUSIONS: This study revealed the most commonly consulted skin side effects of novel anti-cancer drugs and their management in daily practice. We underlie the importance of collaborative work of oncology and dermatology professionals as early management of cutaneous side effects of targeted therapies and ICIs improves patient outcomes.

We investigated the cases with Aeromonas bacteremia in terms of clinical and microbiological characteristics, underlying disease and mortality rates. Patients with positive blood cultures were included in this research. Aeromonas bacteremia was diagnosed as at least one positive blood culture for Aeromonas species. The bacteremia was defined as community origin if the onset was in the community or within 72 hours of hospital admission. The others were considered as nosocomial. All bacteria were defined as Aeromonas with conventional method. Species identification was verified by VITEK system. Antibiotic susceptibility tests were analyzed with the disc diffusion, E-test method or VITEK system. Thirty-three patients were diagnosed with bacteremia due to Aeromonas spp. Hematologic and solid tumors were the leading underlying conditions, followed by cirrhosis. Two patients (6%) had community-acquired infections. Aeromonas hydrophila was the most common isolated bacterium. The crude mortality rate was 36%. 12 patients died and 6 deaths and 4 deaths were detected in patients with bacteremia caused by A. hydrophila and Aeromonas sobria respectively. All strains were resistant to ampicillin and more than 90% of the strains were susceptible to trimethoprim-sulfamethoxazole, fluoroquinolone, third generation cephalosporins, and carbapenems. Aeromonas sp. is not a frequent cause of bacteremia however, it may lead to high mortality rates, especially in the immunocompromised hosts and patients with liver cirrhosis. Nosocomial Aeromonas bacteremia is not uncommon in these populations. Broad-spectrum cephalosporins, piperacillin-tazobactam, fluoroquinolones, and carbapenems remain as effective antimicrobial agents for therapy of Aeromonas bacteremia.
ABSTRACT
BACKGROUND: It is extremely difficult to treat spine disorders with stabilization in patients with rheumatoid arthritis. Because revision rates are significantly higher in rigid stabilization. To date, there is no data about patients with rheumatoid arthritis treated with dynamic stabilization. Our aim was to compare the radiological and clinical results of patients with rheumatoid arthritis who underwent lumbar rigid stabilization or dynamic stabilization with Polyetheretherketone rod (PEEK). METHODS: Patients with degenerative lumbar spine disease with rheumatoid arthritis who underwent dynamic stabilization between 2013 and 2015 and rigid stabilization between 2010 and 2012 were evaluated radiologically for adjacent segment disease, proximal junctional kyphosis, system problem (nonunion, screw loosening, instrumentation failure, pull out). It was also compared according to both the revision rates and the Visual Analog Scale and Oswestry Disability Index scores at the 12th month and 24th month. RESULTS: The difference of decrease in Visual Analog Scale and Oswestry Disability Index scores from preoperative to 12th month between patients who underwent dynamic stabilization and rigid stabilization was statistically insignificant. However, there was a significant difference of increase in Visual Analog Scale and Oswestry Disability Index scores between the 12th month and 24th month of patients who underwent rigid stabilization, compared with patients with dynamic stabilization. In patients with dynamic stabilization, the problems of instrumentation were seen less frequently. Revision rates were high in patients with rigid stabilization when compared the patients with dynamic stabilization. CONCLUSION: Radiological and clinical outcomes in patients with rheumatoid arthritis operated with dynamic stabilization are more significant when compared to rigid stabilization. These patients have lower pain and disability scores in their follow up periods. Revision rates are lower in patients with dynamic stabilization.

The aim of this study is to investigate the combination of cefepime and sulbactam. Sulbactam, when administered , will effectively inhibit all Extended-spectrum beta lactamases (ESBLs) of the microorganism, while cefepime will inhibit the growth of the resistant microorganisms since it will not be hydrolyzed by OXA-48. Forty OXA-48-producing K. pneumoniae strains were investigated for their Minimum inhibitory concentrations (MICs) for carbapenems, cefepime, and cefepime + sulbactam by broth microdilution method. Also, the mutant prevention concentration (MPC)s of cefepime alone or in combination with sulbactam was determined. Additionally, the bactericidal activities of cefepime and cefepime + sulbactam were evaluated by the time-kill curve (TKC) assay against selected strains. Also, the in vitro synergistic activity of cefepime + sulbactam combination was determined by TKC. Based on MIC results, up to 35/40 and 34/40 of the strains were resistant to carbapenems and cefepime, respectively. Cefepime + sulbactam MIC range was lower than those for cefepime alone against all the studied isolates. Moreover, cefepime + sulbactam combination presented lower MPC values than cefepime alone. The synergistic interactions of cefepime + sulbactam were also achieved against studied strains at 24 h. No antagonism was observed against studied K. pneumoniae strains. The findings of this study displayed that cefepime + sulbactam combination had synergistic or additive effect against OXA-48-producing K. pneumoniae strains. Additionally, it was first observed that this combination could display a lower MPC than cefepime alone. Further investigations may be helpful for understanding the effectiveness of cefepime + sulbactam combinations for OXA-48-positive carbapenem-resistant K. pneumoniae isolates.
