Abstract
One of the fluoroquinolone antibiotics, levofloxacin (LEV), is used to treat a variety of illnesses leading to oxidative stress and cellular damage. Peel from Punica granatum is a waste product abundant in phytochemicals with various biological activities. This study aimed to evaluate P. granatum peel extract's (PGPE) potential to mitigate oxidative stress, inflammation, apoptosis, and liver damage caused by LEV. There were four groups of rats: control, PGPE, LEV, and PGPE + LEV, respectively, and they were orally administered their daily treatments for 2 weeks. Results revealed that PGPE has a large number of phytochemical components with high antioxidant activity. PGPE intake alone enhanced the antioxidant status and decreased oxidative stress. On the other hand, pretreatment of the LEV group with PGPE restored oxidative stress, antioxidant enzymes, glutathione content, liver function biomarkers, and hematological parameters. Also, normalization of gene expressions (cyclooxygenase-2, transforming growth factor-beta1, caspase-3, heme oxygenase-1, B cell lymphoma-2, interleukin [IL]-10, and IL-1) and improvement in liver architecture, and immunohistochemical alpha-smooth muscle actin, were seen in comparison to the LEV group. Conclusively, PGPE exhibits strong anti-inflammatory, antiapoptotic, and antioxidant properties that shield rat liver from the damaging effects of LEV and offer a fresh viewpoint on the application of fruit waste products.

Abstract
Legionnaires' disease (LD), caused by the Legionella bacterium, primarily manifests as pneumonia and could result in a spectrum of clinical severity. As treatment necessitates the use of antibiotics, levofloxacin, a fluoroquinolone, is a commonly preferred option due to its broad-spectrum activity. However, the potential side effects of levofloxacin, including rare instances of hepatotoxicity, introduce a therapeutic challenge. This case report explores the association between levofloxacin and hepatotoxicity and its implications for treating LD.

Abstract
Levofloxacin is a broad-spectrum antibiotic that is used in the treatment of many infections. A rare adverse drug reaction following the use of levofloxacin is drug-induced liver injury. The exact mechanism behind fluoroquinolone-induced liver injury is unknown, but many severe, sometimes fatal hepatotoxicity cases are reported. Current recommendations advise clinicians to discontinue levofloxacin immediately if the patient develops signs and symptoms of hepatitis. This case report presents a 79-year-old male who was prescribed levofloxacin 500 mg by mouth daily for seven days. The patient had a past medical history of dementia, seizures, cerebral vascular accident, pulmonary fibrosis, and chronic kidney disease. Upon admission, the patient began to show signs and symptoms of liver injury. We hereby present a case report and a review of significant literature on levofloxacin-induced liver injury.

Abstract
Increased migration, the omnipresent desire to travel, climate change and a globally more mobile population enhance the risk of spreading infectious, tropical pathogens across international borders. In addition to diarrhea and fever, skin diseases present one of the most common reasons for a medical consultation upon return among travelers. These diseases are often caused by parasites. Detailed data on infectious travel diseases is scarce. However, demographic, endemic and travel-related information represent the basic requirements for physicians to choose appropriate diagnostics and adequate treatment for affected patients. This article gives an overview of common parasitic travel dermatoses, their specific diagnostic workup, treatment and preventive measures.

Abstract
Fluoroquinolones are some of the most common antibiotics used by clinicians all over the world. Levofloxacin, a fluoroquinolone, is used therapeutically in numerous countries; however, it can cause an increase in liver function tests and liver dysfunction. The current study was designed to determine the effect of Levofloxacin (40 mg/kg body weight (b.wt.) daily for 2 weeks) on rat liver function and oxidative stress markers as well as to evaluate the potential hepatoprotective effects of Moringa oleifera leaf extract as a known antioxidant herb. M. oleifera leaf extract was found to improve the hepatic dysfunction induced by Levofloxacin by recovering liver enzymatic activities (alanine aminotransferase [ALT], aspartate aminotransferase [AST] and gamma-glutamyl transferase [GGT]) to normal levels. The extract also reversed the antioxidant imbalance as measured by catalase and superoxide dismutase activities as well as by reduced glutathione and malondialdehyde levels. Moreover, M. oleifera leaf extract induced anti-inflammation by improving the production of interleukin (IL)-10. Additionally, its presence attenuated the downregulation of IL-1 induced by Levofloxacin alone from hepatic tissue. It can be concluded that M. oleifera extract can help reduce the side effects caused by Levofloxacin administration.

Abstract
BACKGROUND In recent years, fluoroquinolone research has focused on achieving several goals, including (1) enhanced potency against gram-positive cocci, notably Streptococcus pneumoniae, and anaerobes, while (2) maintaining potency against gram-negative pathogens, (3) optimizing pharmacokinetics and pharmacodynamics (PK/PD), and (4) minimizing potential adverse drug reactions through recognition and avoidance of structural configurations that have characterized earlier, reactive compounds. OBJECTIVE This review examines the efficacy and safety of fluoroquinolones and the specific clinical evidence regarding levofloxacin. METHODS Using published literature collected over time by the author, a review was conducted, focusing on the efficacy and safety profile of levofloxacin and other fluoroquinolones. RESULTS The newer fluoroquinolones have fulfilled many of the research goals described above. Levofloxacin has improved anti-gram-positive potency, PK/PD properties, a proven clinical trial record (particularly for communityacquired pneumonia [CAP]), and an excellent safety profile-in the context of the treatment of >250 million patients worldwide in the past decade. It is licensed for management of drug-resistant S pneumoniae infections in the United States and has gained widespread formulary acceptance and guideline inclusion. Studies assessing levofloxacin for CAP therapy show significant advantages over standard therapy, such as trends toward reduced IV therapy and length of hospitalization, reduced mortality, and significant associated cost reduction. In addition, levofloxacin has proved highly effective in acute exacerbations of chronic bronchitis (AECB), with excellent clinical and bacteriologic results, typical of the class, and significant advantages-in terms of clinical response, overall pathogen eradication, extension of the symptom-free period, and trends toward a reduction in the number of consultation visits and hospitalizations-over standard agents, such as the oral cephalosporins. CONCLUSIONS Levofloxacin offers a combination of documented efficacy and tolerability, and provides an important option for the treatment of bacterial infections, including CAP and AECB, compared with standard agents used in the management of lower respiratory tract infections.

Abstract
Antimicrobial agents are important causes of drug-induced liver injury. They are responsible for about 45% of cases of drug hepatotoxicity. Hepatic damage mechanisms are intrinsic or idiosyncratic. Usually, antibiotics are responsible for idiosyncratic toxicity. This review summarizes the rate of incidence and clinical features of hepatotoxicity due to antibiotics and chemotherapics, with particular attention to data regarding paediatric population. Liver injury features have been systematically evaluated for the most commonly administered antibiotics and chemotherapics in adults, even though there is little information about other widely used compounds, as cephalosporine or clarithromycin, and about antibiotics active against multi-resistant bacteria, as carbapenems, vancomycin, clindamycin, and linezolid. By contrast, there is an abundance of case reports in paediatrics, but very few structured studies have been carried out in children. Children are an important class of antibiotic users, with specific metabolic characteristics, so more studies on them should be carried out.

Abstract
BACKGROUND & AIMS Fluoroquinolone-induced liver injury is rare; no prospective studies of well-characterized case series have been published. We studied patients with fluoroquinolone-induced hepatotoxicity from the Drug-Induced Liver Injury Network (DILIN) to characterize injury patterns, outcomes, and associated features. METHODS We identified subjects with fluoroquinolone hepatotoxicity enrolled in the DILIN from September 2004 to January 2010. Demographic, clinical, and laboratory data were analyzed by descriptive statistical methods. RESULTS Of the 679 registrants in the DILIN prospective study, 12 had fluoroquinolone hepatotoxicity (6 ciprofloxacin, 4 moxifloxacin, 1 levofloxacin, and 1 gatifloxacin). Seven were women; median age was 57 years (range, 23-80 years), and median time from fluoroquinolone start to symptoms was only 4 days (range, 1-39 days). Nine patients developed symptoms on medication; 3 did so 2, 8, and 32 days after stopping the medication. Cases were equally distributed among hepatocellular injury (predominantly increased levels of alanine aminotransferase), cholestatic injury (predominantly increased levels of alkaline phosphatase), and both. Seven patients had immunoallergic features. Patients with mixed hepatocellular and cholestatic injury had mild disease without jaundice; all recovered. In contrast, 2 of 4 patients with hepatocellular injury and jaundice died, 1 of acute liver failure. One patient with cholestatic injury developed vanishing bile duct syndrome and required liver transplantation; another had a persistently increased serum level of alkaline phosphatase. CONCLUSIONS Fluoroquinolone liver injury is rapid in onset and often has immunoallergic features, indicating a hypersensitivity reaction. The pattern of injury can be hepatocellular, cholestatic, or mixed; mixed cases are the least severe. Acute and chronic liver failure can occur.

Abstract
Antibiotics used by general practitioners frequently appear in adverse-event reports of drug-induced hepatotoxicity. Most cases are idiosyncratic (the adverse reaction cannot be predicted from the drug's pharmacological profile or from pre-clinical toxicology tests) and occur via an immunological reaction or in response to the presence of hepatotoxic metabolites. With the exception of trovafloxacin and telithromycin (now severely restricted), hepatotoxicity crude incidence remains globally low but variable. Thus, amoxicillin/clavulanate and co-trimoxazole, as well as flucloxacillin, cause hepatotoxic reactions at rates that make them visible in general practice (cases are often isolated, may have a delayed onset, sometimes appear only after cessation of therapy and can produce an array of hepatic lesions that mirror hepatobiliary disease, making causality often difficult to establish). Conversely, hepatotoxic reactions related to macrolides, tetracyclines and fluoroquinolones (in that order, from high to low) are much rarer, and are identifiable only through large-scale studies or worldwide pharmacovigilance reporting. For antibiotics specifically used for tuberculosis, adverse effects range from asymptomatic increases in liver enzymes to acute hepatitis and fulminant hepatic failure. Yet, it is difficult to single out individual drugs, as treatment always entails associations. Patients at risk are mainly those with previous experience of hepatotoxic reaction to antibiotics, the aged or those with impaired hepatic function in the absence of close monitoring, making it important to carefully balance potential risks with expected benefits in primary care. Pharmacogenetic testing using the new genome-wide association studies approach holds promise for better understanding the mechanism(s) underlying hepatotoxicity.

Abstract
BACKGROUND Levofloxacin is a fluoroquinolone used globally to treat respiratory, skin, and genitourinary tract infections. It is generally well tolerated and there is a very low risk for liver injury in patients taking this antibiotic. OBJECTIVE We report an acute case of hepatitis following treatment with levofloxacin for pneumonia. CASE SUMMARY A 77-year-old white male (height, 162 cm; weight, 58 kg) with chronic bronchitis presented to the emergency department of the Hospital Curry Cabral, Lisbon, Portugal, with respiratory difficulty and productive cough. The patient had a history of chronic bronchitis, arterial hypertension, hypercholesterolemia, and benign prostatic hyperplasia, and was being treated with salmeterol 50 μg plus fluticasone 250 μg BID, and amlodipine 5 mg, simvastatin 20 mg, alfuzosin 10 mg, and finasteride 5 mg once daily. Initially, the patient refused admission and was sent home, medicated with levofloxacin 500 mg once daily (single dose) for pneumonia and acetaminophen 1 g (as needed, maximum TID) if axillary temperature exceeded 38.0°C (100.4°F). Three days later, the patient returned for a follow-up visit, and despite clinical and radiologic improvement, blood tests revealed a slight aggravation of anemia. On the seventh day of treatment with levofloxacin, the patient showed an elevation of transaminases. The temporal relation between the use of levofloxacin and the liver injury, the exclusion of other causes of hepatitis, and a compatible liver biopsy (conducted 14 days after identification of hepatitis) was consistent with the diagnosis of levofloxacin-associated hepatotoxicity. Levofloxacin treatment was stopped and the patient made a full recovery. The Naranjo Adverse Drug Reaction Probability Scale score for this association was "probable" (score 7) and the Roussel Uclaf Causality Assessment Method Scale score was "highly probable" (score 9). Unlike the 5 reported cases in the literature, this is the only case in which both a liver biopsy was performed in the course of the disease and the patient survived. CONCLUSION The acute hepatitis observed in this elderly patient was probably associated with the administration of levofloxacin.

Abstract
Objective To report a case of elevated hepatic transaminases in a patient receiving ciprofloxacin that resolved upon discontinuation and initiation of levofloxacin. Summary A 45-year-old white woman was initiated on ciprofloxacin and gentamicin after a blood culture revealed gram-negative rods. On day 2 of antibiotic therapy, the patient's aspartate aminotransferase (AST) and alanine aminotransferase (ALT) increased to 2,352 units/L and 783 units/L, respectively, and remained elevated for the following 4 days. Baseline AST and ALT were within normal limits. On day 5 of therapy, ciprofloxacin was discontinued and levofloxacin was initiated. On the following day, the hepatic transaminases decreased (AST, 192 units/L; ALT, 582 units/L) and continued to normalize prior to hospital discharge. On a subsequent admission later in the month, levofloxacin was again administered for treatment of a gram-positive bacteremia, with no subsequent elevation of hepatic transaminases. Discussion An objective causality assessment revealed that the adverse drug reaction (ADR) was probable. Although reports of this ADR have been noted, there is no previously documented occurrence of resolution of elevated hepatic transaminases on therapeutic modification to another fluoroquinolone. Conclusion Ciprofloxacin may significantly elevate hepatic transaminases. The clinician should be aware of the unique ADR profiles of the different fluoroquinolones because hepatotoxicity may not be a class effect.

Abstract
Completing its initial phases of drug development in the mid 1990s as the one of the first fluoroquinolones that could be used with confidence to treat respiratory tract infections, levofloxacin went on to become one of the most widely prescribed antibiotics in the world. Available in both oral (po) and intravenous (IV) formulations and with characteristics of over 90% bioavailability, distribution into both extracellular and intracellular pulmonary compartments, highly predictable pharmacokinetics with over 90% of the drug being excreted unchanged in urine, and reliable activity against a broad spectrum of clinically important pathogens, levofloxacin has been used successfully to treat patients with a variety of serious infectious diseases as well as common infections most often treated outside of the hospital setting. Results of clinical trials involving patients with respiratory tract, urinary tract, and skin infections have consistently shown rates of clinical success and bacteriological eradication that were comparable to other widely used broad-spectrum agents. Regimens of levofloxacin, initially involving total daily doses of 250 mg to 500 mg, but more recently regimens involving 750 mg doses, have been shown to be safe and effective. Nearly a decade and a half of clinical experience has defined a safety and tolerability profile that permits data-driven assessment of the risks and benefits of using levofloxacin. As resistance to currently available fluoroquinolones has emerged, the clinical value of levofloxacin deserves continued evaluation. However, consistently high rates of susceptibility of clinically important bacteria, especially among those bacteria that commonly cause respiratory tract infections, such as Streptococcus pneumoniae and Haemophilus influenzae, suggest that this agent will continue to be a widely used well past the 20-year anniversary of its introduction into the antibacterial armamentarium.

Abstract
The spectrum of drug-induced liver injury (DILI) is both diverse and complex. The first step in diagnosis is a suspicion of DILI based on careful consideration of recent comprehensive reports on the disease. There are some situations in which the suspicion of DILI is particularly strong. Exclusion of other possible etiologies according to the pattern of liver injury is essential for the diagnosis. In patients with suspected DILI, diagnostic scales, such as the Councils for International Organizations of Medical Sciences/Roussel Uclaf Causality Assessment Method (CIOMS/RUCAM) scale, may be helpful for the final diagnosis. Early management of DILI involves prompt withdrawal of the drug suspected of being responsible, according to serum levels of alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total bilirubin (T-Bil). However, as DILI patients may show resolution of liver injury without discontinuation of the drug, it should be carefully evaluated whether the suspected drug should be discontinued immediately with adequate consideration of the importance of the medication.

Early management of DILI involves prompt withdrawal of the drug suspected of being responsible, according to serum levels of alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total bilirubin (T-Bil). However, as DILI patients may show resolution of liver injury without discontinuation of the drug, it should be carefully evaluated whether the suspected drug should be discontinued immediately with adequate consideration of the importance of the medication.

Abstract
The spectrum of drug-induced liver injury (DILI) is both diverse and complex. The first step in diagnosis is a suspicion of DILI based on careful consideration of recent comprehensive reports on the disease. There are some situations in which the suspicion of DILI is particularly strong. Exclusion of other possible etiologies according to the pattern of liver injury is essential for the diagnosis. In patients with suspected DILI, diagnostic scales, such as the Councils for International Organizations of Medical Sciences/Roussel Uclaf Causality Assessment Method (CIOMS/RUCAM) scale, may be helpful for the final diagnosis. Early management of DILI involves prompt withdrawal of the drug suspected of being responsible, according to serum levels of alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total bilirubin (T-Bil). However, as DILI patients may show resolution of liver injury without discontinuation of the drug, it should be carefully evaluated whether the suspected drug should be discontinued immediately with adequate consideration of the importance of the medication.

Abstract
BACKGROUND Fluoroquinolones, including ciprofloxacin, levofloxacin, gemifloxacin, and moxifloxacin, represent a major advance in the development of antimicrobial agents. They offer significant activity against Gram-negative pathogens, while more advanced generation fluoroquinolones including levofloxacin, gemifloxacin, and moxifloxacin are significantly active against Gram-positive (e.g., Streptococcus pneumoniae for some members of the class), typical, atypical, and anaerobic pathogens. Fluoroquinolones have a pharmacokinetic/pharmacodynamic profile that exhibits concentration-dependent killing and good oral absorption, allowing for once-daily dosing. OBJECTIVE Review of data from fluoroquinolone studies, with an emphasis on the associated rare, but potentially clinically important, adverse events in specific patient populations. Review of clinical efficacy is included where relevant to the topic under discussion. METHODS A literature search was conducted using terms including fluoroquinolones, moxifloxacin, ciprofloxacin, levofloxacin, gatifloxacin, gemifloxacin, safety, adverse events, drug interactions, and pharmacokinetic parameters to identify literature providing information regarding the safety profile of specified fluoroquinolones in special patient populations (i.e., the elderly, patients with liver disease, kidney disease, glycemic disorder, those at risk for cardiovascular events). Although specific date criteria were not applied to the search, preference was given to more recent publications. Online databases searched include MEDLINE and EMBASE and relevant textbooks were utilized as well. FINDINGS Fluoroquinolones, when used either as monotherapy or as combination therapy depending on their individual indications, attain adequate concentrations for treating infections in different target sites, including epithelial lining fluid, alveolar macrophages, skin, and gastrointestinal tissues. Overall, fluoroquinolones have predictable and mild-to-moderate adverse-event profiles and are generally well tolerated. Findings of this review are limited by the availability of publications and case reports. CONCLUSIONS Fluoroquinolones, are associated with rare, but clinically important, adverse events in special patient populations (including the elderly; those with hepatic, renal, or glycemic disorders; and those at risk for cardiovascular events). Recognition of differences in the clinical efficacy and safety profiles of fluoroquinolones in special patient populations should lead to better antimicrobial agent selection.

Abstract
OBJECTIVE To report a case of possible levofloxacin-induced acute fulminant hepatic failure. CASE SUMMARY An unconscious 55-year-old woman was hospitalized with the diagnosis of hepatic encephalopathy. The patient had received levofloxacin 500 mg daily for 10 days because of an upper respiratory infection. Her past medical history revealed hepatitis B surface antigen positivity as an asymptomatic hepatitis B virus carrier for 10 years. After hospitalization, treatment included plasmapheresis and supportive care. The patient's consciousness improved on the second day of treatment. Other etiologies of fulminant hepatic failure were ruled out, suggesting levofloxacin-induced fulminant hepatic failure. Although the patient received supportive treatment, her condition gradually deteriorated and she died 12 weeks after admission to our hospital. An objective causality assessment revealed that the adverse event was possibly related to levofloxacin. DISCUSSION Levofloxacin is widely used because of its broad spectrum of antimicrobial activity. As of August 9, 2005, to our knowledge, only one case of fulminant hepatic failure in relation to levofloxacin has previously been published. We believe that, in our patient, the relationship between levofloxacin and her illness is clear because of the negative results in the etiological studies, the short time between the drug's administration and the development of disease, and the pathologic findings suggestive of drug-induced hepatitis. CONCLUSIONS Clinicians should be aware of the possibility of severe hepatic injury associated with levofloxacin when prescribing this drug.

Abstract
PURPOSE OF REVIEW Quinolones are potent antibacterial agents that can cause drug hypersensitivity reactions affecting different organs. A better understanding of the underlying mechanism and the level of crossreactivity within different quinolones is needed to handle and prevent these diseases. RECENT FINDINGS The adverse side-effects caused by quinolones are the result of different immunological mechanisms and cause quite different diseases. The development of an assay detecting quinolone-specific IgE revealed specific antibodies in more than 50% of patients with immediate-type reactions, and the majority of sera also reacted with related compounds. In maculopapular drug exanthemas caused by ciprofloxacin, specific T cells could be detected and cloned. They reacted with ciprofloxacin directly, and crossreactivity to related compounds was detected in approximately 50% of the clones. SUMMARY Quinolones can cause drug hypersensitivity reactions by different immunological mechanisms. In-vitro analysis suggests that crossreactivity is common.
