Complications Of Cellulitis In Diabetic Foot Infections

Complications Of Cellulitis In Diabetic Foot Infections

US Pharm. 2011;36(8):63-66. Patients with diabetes have a 30-fold higher risk of lower-extremity amputation due to infection compared with patients without diabetes.1,2 Diabetic foot infections that are not appropriately treated because of delayed diagnosis or that are inadequately treated lead to lower-extremity amputation in approximately 10% of patients.3,4 Lower-extremity amputations may be debilitating and can dramatically affect the patient’s quality of life. Successful outcome depends upon prompt identification of the infection, followed by appropriate antibiotic therapy in conjunction with good wound care and judicious use of surgical procedures when warranted.4,5 Community pharmacists can play an integral role in educating patients about foot care and in recognizing ulcers that can lead to skin infections such as cellulitis, which involves the epidermis, dermis, and—in more complicated cases—subcutaneous tissue.6 Resulting from a cut, abrasion, trauma, or puncture, cellulitis may lead to diabetic foot infection. The presence of a foot wound does not necessarily signify infection; however, an existing infection must be treated. Infection is indicated by the presence of purulent secretions or at least two of the following symptoms: erythema, warmth, tenderness, pain, and induration. The clinician should also be alert for friable tissue, wound tenderness, and/or foul odor.3 Risk Factors Patients with diabetes have a 12% to 25% risk of developing diabetic foot infections due to neuropathy—sensory, motor, and/or autonomic disturbances in which the patient loses the ability to recognize injury or excessive pressure, resulting in foot ulcerations that can develop into infection.3 In addition, peripheral arterial disease impairs blood flow and restricts the bod Continue reading >>

The Treatment Of Diabetic Foot Infections: Focus On Ertapenem

The Treatment Of Diabetic Foot Infections: Focus On Ertapenem

The treatment of diabetic foot infections: focus on ertapenem Diabetic Foot Clinic, King’s College Hospital, Denmark Hill, London, UK Correspondence: Michael Edmonds, Diabetic Foot Clinic, King’s College Hospital, Denmark Hill, London, UK, Email [email protected] Copyright © 2009 Edmonds, publisher and licensee Dove Medical Press Ltd.

Clinically, 3 distinct stages of diabetic foot infection may be recognized: localized infection, spreading infection and severe infection. Each of these presentations may be complicated by osteomyelitis. Infection can be caused by Gram-positive aerobic, and Gram-negative aerobic and anaerobic bacteria, singly or in combination. The underlying principles are to diagnose infection, culture the bacteria responsible and treat aggressively with antibiotic therapy. Localized infections with limited cellulitis can generally be treated with oral antibiotics on an outpatient basis. Spreading infection should be treated with systemic antibiotics. Severe deep infections need urgent admission to hospital for wide-spectrum intravenous antibiotics. Clinical and microbiological response rates have been similar in trials of various antibiotics and no single agent or combination has emerged as most effective. Recently, clinical and microbiological outcomes for patients treated with ertapenem were equivalent to those for patients treated with piperacillin/tazobactam. It is also important to judge the need for debridement and surgery, to assess the arterial supply to the foot and consider revascularization either by angioplasty or bypass if the foot is ischemic. It is a Continue reading >>

Management Of Diabetic Foot Ulcers

Management Of Diabetic Foot Ulcers

INTRODUCTION The lifetime risk of a foot ulcer in patients with diabetes (type 1 or 2) may be as high as 25 percent [1-3]. Diabetic foot ulcers are a major cause of morbidity and mortality, accounting for approximately two-thirds of all nontraumatic amputations performed in the United States [4,5]. Infected or ischemic diabetic foot ulcers account for approximately 25 percent of all hospital stays for patients with diabetes [6]. These observations illustrate the importance of prompt and appropriate treatment of foot ulcers in patients with diabetes. The management of diabetic foot ulcers, including local wound care, use of mechanical offloading, treatment of infection, and indications for revascularization are reviewed here. The evaluation of the diabetic foot and specific management of the threatened limb are reviewed separately. (See "Evaluation of the diabetic foot" and "Treatment of chronic lower extremity critical limb ischemia".) ETIOLOGY Risk factors that can lead to foot wounds in patients with diabetes include loss of protective sensation due to neuropathy, prior ulcers or amputations, foot deformity leading to excess pressure, external trauma, infection, and the effects of chronic ischemia, typically due to peripheral artery disease [1]. Patients with diabetes also have an increased risk for nonhealing related to mechanical and cytogenic factors, as well as a high prevalence of peripheral artery disease. (See "Evaluation of the diabetic foot", section on 'Risk factors'.) ULCER CLASSIFICATION The first step in managing diabetic foot ulcers is assessing, grading, and classifying the ulcer. Classification is based upon clinical evaluation of the extent and depth of the ulcer and the presence of infection or ischemia, which determine the nature and intensity of tr Continue reading >>

Choice Of Wound Care In Diabetic Foot Ulcer: A Practical Approach

Choice Of Wound Care In Diabetic Foot Ulcer: A Practical Approach

Go to: Definition Infection, ulceration or destruction of deep tissues associated with neurological abnormalities and various degrees of peripheral vascular diseases in the lower limb (World Health Organization definition, 1995). Risk factors Diabetic foot ulcers are a consequence of many factors including loss of protective sensation due to peripheral neuropathy where the feet become numb and the injury goes unnoticed. Also, arterial insufficiency complicates the neuropathic ulcer which leads to poor wound healing. Foot deformity and calluses can result in high plantar pressure, which results in additional risk. Mechanical stress at the wound site is hypothesized to affect wound healing[7]. Many other factors contribute to the risk of foot ulceration and its subsequent infection in patients with diabetes. Uncontrolled hyperglycemia, duration of diabetes, trauma, improper footwear, callus, history of prior ulcers/amputations, older age, blindness/impaired vision, chronic renal disease and poor nutrition have also been demonstrated to play a role in the pathogenesis and progression of diabetic foot ulceration. Infection further deteriorates the diabetic foot resulting in a non-healing chronic wound. Recently, vitamin D deficiency was proposed as a risk factor for diabetic foot infection[8]. Classification Based on the Red-Yellow-Black[9] wound classification system by Marion Laboratories, wounds can be classified as follows[10]: (1) Necrotic tissue-either dry or infected and usually black or dark green in color as shown in Figure 1A; (2) Sloughy tissue-combination of wound exudate and debris forming a glutinous yellow layer of tissue over the wound which is often mistaken for infection as shown in Figure 1B; (3) Granulating tissue-highly vascularized, red in color and so Continue reading >>

First-line Antibiotics For Diabetic Foot Ulcers

First-line Antibiotics For Diabetic Foot Ulcers

First-line antibiotics for diabetic foot ulcers First-line antibiotics for diabetic foot ulcers What are the first-line antibiotics for the treatment of diabetic foot ulcers? Andrew Boulton:First of all, Ican tell you that not all diabetic foot ulcers require antibiotic treatment. Indeed, if there is no clinical evidence for infection there was one of the very few randomized controlled trials that showed that if there is no clinical infection, you did just as well without an antibiotic as with one. If you got aclinically infected ulcer, to be quite honest there are no randomized controlled trials to tell us which to use first. Iwould normally start with something broad-spectrum, such as co-amoxiclav, or Augmentin, or clindamycin, which has good bone penetration. Then, when you have got results of tissue specimens, awound swab is awaste of time you need to debride the wound and get adeep-tissue specimen to the laboratory. That can help guide to target the organism that is likely the infecting one. Continue reading >>

Diabetic Foot Ulcer

Diabetic Foot Ulcer

Diabetic foot ulcer is a major complication of diabetes mellitus, and probably the major component of the diabetic foot. Wound healing is an innate mechanism of action that works reliably most of the time. A key feature of wound healing is stepwise repair of lost extracellular matrix (ECM) that forms the largest component of the dermal skin layer.[1] But in some cases, certain disorders or physiological insult disturbs the wound healing process. Diabetes mellitus is one such metabolic disorder that impedes the normal steps of the wound healing process. Many studies show a prolonged inflammatory phase in diabetic wounds, which causes a delay in the formation of mature granulation tissue and a parallel reduction in wound tensile strength.[2] Treatment of diabetic foot ulcers should include: blood sugar control, removal of dead tissue from the wound, wound dressings, and removing pressure from the wound through techniques such as total contact casting.[3] Surgery in some cases may improve outcomes.[3] Hyperbaric oxygen therapy may also help but is expensive.[3] It occurs in 15% of people with diabetes,[4] and precedes 84% of all diabetes-related lower-leg amputations.[5] Classification[edit] Diabetic foot ulcer is a complication of diabetes. Diabetic foot ulcers are classified as either neuropathic, neuroischaemic or ischaemic.[6] Risk factors[edit] Risk factors implicated in the development of diabetic foot ulcers are infection, older age,[7] diabetic neuropathy, peripheral vascular disease, cigarette smoking, poor glycemic control, previous foot ulcerations or amputations,[5] and ischemia of small and large blood vessels.[8][9] Prior history of foot disease, foot deformities that produce abnormally high forces of pressure, renal failure, oedema, impaired ability to look Continue reading >>

Antibiotics To Treat Foot Infections In People With Diabetes

Antibiotics To Treat Foot Infections In People With Diabetes

Antibiotics to treat foot infections in people with diabetes We reviewed the effects on resolution of infection and safety of antibiotics given orally or intravenously (directly into the blood system) in people with diabetes that have a foot infection. One of the most frequent complications of people with diabetes is foot disorders, specially foot ulcers or wounds. These wounds can easily become infected, and are known as a diabetic foot infections (DFIs). If they are not treated, the infection can progress rapidly, involving deeper tissues and threatening survival of the limb. Sometimes these infections conclude with the affected limb needing to be amputated. Most DFIs require treatment with systemic antibiotics, that is, antibiotics that are taken orally, or are inserted straight into the bloodstream (intravenously), and affect the whole body. The choice of the initial antibiotic treatment depends on several factors such as the severity of the infection, whether the patient has received another antibiotic treatment for it, or whether the infection has been caused by a micro-organism that is known to be resistant to usual antibiotics (e.g. methicillin-resistant Staphylococcus aureus - better known as MRSA). The objective of antibiotic therapy is to stop the infection and ensure it does not spread. There are many antibiotics available, but it is not known whether one particular antibiotic - or type of antibiotic - is better than the others for treatment of DFIs. We searched through the medical literature up to March 2015 looking for randomised controlled trials (which produce the most reliable results) that compared different systemic antibiotics against each other, or against antibiotics applied only to the infected area (topical application), or against a fake medici Continue reading >>

Nonsurgical Treatment For Diabetic Foot Ulcers

Nonsurgical Treatment For Diabetic Foot Ulcers

To help a diabetic foot ulcer heal, doctors at NYU Langone clean and disinfect the area. If the ulcer is infected, your doctor prescribes antibiotics to clear it up and prevent it from traveling to a bone in the foot. Your doctor can refer you to an NYU Langone vascular specialist for additional medication if you have lower extremity arterial disease, a condition that impairs blood flow to the legs and feet and can cause an ulcer to heal more slowly. NYU Langone doctors recommend regular wound care for foot ulcers, as well as other therapies. Wound Care As your doctor cleans and disinfects the ulcer, he or she also removes any dead tissue surrounding it. After the wound is clean, the doctor applies bandages to keep the area sterile while it heals. Your doctor can show you how to clean and dress the wound at home and may recommend using a topical antibacterial ointment to help speed healing and prevent further infection. Daily wound care should continue until the wound has healed. People with diabetes and lower extremity arterial disease often heal slowly, so it may take weeks or months for a foot ulcer to heal completely. Hyperbaric Oxygen Therapy NYU Langone’s Helen L. and Martin S. Kimmel Hyperbaric and Advanced Wound Healing Center at the Ambulatory Care Center is the only outpatient facility in Manhattan that offers monoplace chamber hyperbaric oxygen therapy. Doctors prescribe this treatment to help speed the healing of soft tissue damage caused by a foot ulcer. In this therapy, a person lies on his or her back on a comfortable bed inside an enclosed, transparent chamber. The chamber is connected to a machine that fills the space with 100 percent oxygen. Breathing pure oxygen increases the amount of oxygen in the bloodstream ten-fold. Oxygen-rich blood can signif Continue reading >>

Diabetic foot can be defined as any foot pathology that results directly from diabetes mellitus or its long-term complications.[ 1 ] This is one of the most common complications of diabetes mellitus requiring in hospitalization for not only leading to significant morbidity an expensive investigations and costly treatment but also for progression to limb-threatening and life-threatening diabetic foot infection. The two main causes of diabetic foot wounds are neuropathy and ischemia.[ 2 ] Among the diabetic patients, the prevalence of foot ulcer ranged from 12% to 25%.[ 3 ] Diabetic foot wounds are prone to get infected which spread through soft tissue and the bone as a result of impaired defense mechanisms and delayed process of wound healing[ 4 ] advancing the wound age. A study from South India reported the prevalence of infection among patients with diabetic foot up to 11%.[ 5 ] Similar studies are not many from the vast Continue reading >>

(1)University of Geneva, Geneva University Hospitals and Medical School, Service of Infectious Diseases , 4, rue Gabrielle Perret-Gentil, 1211 Geneva 14 , Switzerland +41 22 372 33 11 ; [email protected] INTRODUCTION: Diabetic foot ulcers, especially when they become infected, are aleading cause of morbidity and may lead to severe consequences, such asamputation. Optimal treatment of these diabetic foot problems usually requires a multidisciplinary approach, typically including wound debridement, pressureoff-loading, glycemic control, surgical interventions and occasionally otheradjunctive measures.AREAS COVERED: Antibiotic therapy is required for most clinically infectedwounds, but not for uninfected ulcers. Unfortunately, clinicians often prescribe antibiotics when they are not indicated, and even when indicated the regimen isfrequently broader spectrum than needed and given for longer than necessary. Manyagents are available for intravenous, oral or topical therapy, but no singleantibiotic or combination is optimal. Overuse of antibiotics has negative effectsfor the patient, the health care system and society. Unnecessary antibiotictherapy further promotes the problem of antibiotic resistance.EXPERT OPINION: The rationale for prescribing topical, oral or parenteralantibiotics for patients with a diabetic foot wound is to treat clinicallyevident infection. Available published evidence suggests that there is no reason to prescribe antibiotic therapy for an uninfected foot wound as eitherprophylaxis against infection or in the hope that it will hasten healing of thewound.

Scaffolds, Antibiotics Show Promise In Treating Diabetic Foot Sores

Scaffolds, Antibiotics Show Promise In Treating Diabetic Foot Sores

Scaffolds, antibiotics show promise in treating diabetic foot sores Re-amputation rate falls with Vacuum Assisted Closure. Osteoset-T beads and KeraPac dressing show potential benefits. Existing technologies such as acellular tissue scaffolds offer safe and effective ways to treat diabetic foot ulcers. Now some new products, including negative pressure wound therapy, living-tissue scaffolds and topical treatments, may offer physicians even more ammunition in the fight against bone infection and amputation. The NPWT patients were only 25% as likely as control group patients to need a second amputation. One new treatment method, Vacuum Assisted Closure, a form of negative pressure wound therapy (NPWT), is a potential blockbuster treatment for partial diabetic foot amputation wounds, said David Armstrong, DPM, PhD, professor of surgery, chair of research and assistant dean at the Dr. William M. Scholl College of Podiatric Medicine at Rosalind Franklin University of Medicine and Science in North Chicago, Ill. NPWT may yield a higher percentage of healed wounds, faster healing rates and fewer re-amputations than standard care, Armstrong said. Armstrong, considered a leading expert on diabetic foot ulcers, teamed up with Lawrence Lavery, DPM, of the Texas A&M University Health Science Center College of Medicine, on a 16-week randomized controlled clinical trial comparing NPWT to standard therapy for partial foot amputation wounds in people with diabetes. They published their findings in The Lancet. NPWT provides intermittent or continuous subatmospheric pressure through a pump connected to foam dressing, with an adhesive drape to maintain a closed environment. The keratinocytes are grown on the beads and placed in a bag, similar to teabag. Riley S. Rees Essentially, what tha Continue reading >>

LYRICA is contraindicated in patients with known hypersensitivity to pregabalin or any of its other components. Angioedema and hypersensitivity reactions have occurred in patients receiving pregabalin therapy. There have been postmarketing reports of hypersensitivity in patients shortly after initiation of treatment with LYRICA. Adverse reactions included skin redness, blisters, hives, rash, dyspnea, and wheezing. Discontinue LYRICA immediately in patients with these symptoms. There have been postmarketing reports of angioedema in patients during initial and chronic treatment with LYRICA. Specific symptoms included swelling of the face, mouth (tongue, lips, and gums), and neck (throat and larynx). There were reports of life-threatening angioedema with respiratory compromise requiring emergency treatment. Discontinue LYRICA immediately in patients with these symptoms. Antiepileptic drugs (AEDs) including LYRICA increase the risk of suicidal thoughts or behavior in patients taking AEDs for any indication. Monitor patients treated with any AED for any indication for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior. Pooled analyses showed clinical trial patients taking an AED had approximately twice the risk of suicidal thoughts or behavior than placebo-treated patients. The estimated incidence rate of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43%, compared to 0.24% among 16,029 placebo-treated patients, representing an increase of approximately one patient for every 530 patients treated with an AED. The most common adverse reactions across all LYRICA clinical trials are dizziness, somnolence, dry mouth, edema, blurred vision, weight gain, constipation, euphoric mood, balance Continue reading >>

High Rates Of Antibiotic Resistance In Infected Diabetic Foot Ulcers

High Rates Of Antibiotic Resistance In Infected Diabetic Foot Ulcers

High Rates of Antibiotic Resistance in Infected Diabetic Foot Ulcers High Rates of Antibiotic Resistance in Infected Diabetic Foot Ulcers In patients treated with early ambulatory surgical debridement (EASD) to avoid amputation resulting from infected diabetic foot ulcers , there was a high frequency of positive extended spectrum beta-lactamase (ESBL) Enterobacteriaceae and methicillin-resistant Staphylococcus aureus (MRSA) and high resistance to antibiotics such as ciprofloxacin, ceftriaxone, and clindamycin, according to research presented at ENDO 2017, April 1-4, in Orlando, Florida. Marlon Yovera-Aldana from the National University of Piura in Peru, and colleagues conducted a cross-sectional study at the Edgardo Rebagliati Martins National Hospital between 2010 and 2014. They evaluated aerobic bacteria cultures from 88 patients who had undergone EASD. Cultures were taken from the base of the ulcer after debridement. Of the 88 patients, 81.8% were men with an average age of 60.612.6. Median time for diabetes was 15 years; hemoglobin A1c was lower than 7% in only 18.7% of patients. Using the Meggitt-Wagner classification, the severity of the foot ulcers were: 39.8% grade 3; 40.9% grade 4; and 1.1% grade 5. Infection severity, as defined by the Infectious Diseases Society of America, were: mild in 11.4%; moderate in 80.7%; and severe in 7.9% of patients. The most frequent isolated bacteria were: In Gram-negative bacteria, 32% were ESBL-positive Enterobacteriaceae. Enterobacteriaceae showed no resistance to carbapenems, but P aeruginosashowed an 80% to 100% resistance. In ESBL-negativeEnterobacteriaceae,69% of patients were resistant to ciprofloxacin and 56% wereresistant to ceftriaxone.While Acinetobacter baumanniiwas found in only 2.3% of cases, it showed 100% resist Continue reading >>

Empirical Therapy For Diabetic Foot Infections: Are There Clinical Clues To Guide Antibiotic Selection? - Sciencedirect

Volume 13, Issue 4 , April 2007, Pages 351-353 Empirical therapy for diabetic foot infections: are there clinical clues to guide antibiotic selection? Author links open overlay panel B.A.Lipskyab Initial antibiotic therapy for diabetic foot infections is usually empirical. Several principles may help to avoid selecting either an unnecessarily broad or inappropriately narrow regimen. First, clinically severe infections require broad-spectrum therapy, while less severe infections may not. Second, aerobic Gram-positive cocci, particularly Staphylococcus aureus (including methicillin-resistant S. aureus (MRSA) for patients at high-risk) should always be covered. Third, therapy should also be targeted at aerobic Gram-negative pathogens if the infection is chronic or has failed to respond to previous antibiotic therapy. Fourth, anti-anaerobe agents should be considered for necrotic or gangrenous infections on an ischaemic limb. Parenteral therapy is needed for severe infections, but oral therapy is adequate for most mild or moderate infections. Continue reading >>
