I also found it interesting that in this trial from Europe, median antibiotic treatment duration was 15 days in both arms of the study. Blood cultures should be obtained and cultures of skin biopsy or aspirate considered for patients with malignancy, severe systemic features (such as high fever and hypotension), and unusual predisposing factors, such as immersion injury, animal bites, neutropenia, and severe cell-mediated immunodeficiency [42]. In most cases of abscess, drainage is critical for optimal therapy [132]. XX. This can occur during “initial” episode fever and neutropenia (first episode of neutropenic fever that requires systemic antimicrobial therapy) or during a “persisting episode” (persistent neutropenic fever unresponsive to broad-spectrum antimicrobial therapy beyond days 4–7) or during recurrent episodes of fever and neutropenia. The initial lesion can be trivial, such as a minor abrasion, insect bite, injection site (as in drug addicts), or boil, and a small minority of patients have no visible skin lesion. Information was requested regarding employment, consultancies, stock ownership, honoraria, research funding, expert testimony, and membership on company advisory committees. Although many specific variations of necrotizing soft tissue infections have been described based on etiology, microbiology, and specific anatomic location of the infection, the initial approach to diagnosis, antimicrobial treatment, and surgical intervention is similar for all forms and is more important than determining the specific variant. Dermatologic manifestations in patients with fever and neutropenia include erythematous maculopapular lesions, focal or progressive cellulitis, cutaneous nodules, “ecthyma gangrenosum,” and, occasionally, necrotizing fasciitis or myonecrosis [179, 200]. Patients were excluded if they were discharged to hospice, transitioned to “comfort measures only” during admission, discharged against medical advice, pregnant, had neutropenic fever at the time of bacteremia, were lost to follow-up, died after discharge of unknown causes, died before a plan for antibiotic duration was determined, had bacteremia from a non-SA organism leading to alteration in the treatment regimen, or developed complicated SAB before hospital discharge. Aspergillus, Rhizopus, and Mucor species cause painful erythematous skin nodules that become necrotic and can resemble ecthyma gangrenosum because of their tendency for angioinvasion [222]. Cutaneous abscesses can be polymicrobial, containing regional skin flora or organisms from the adjacent mucous membranes, but S. aureus alone causes a large percentage of skin abscesses, with a substantial number due to MRSA strains [16–18]. Between 65% and 70% of adult patients are seropositive for VZV, and this identifies those patients at risk for future reactivation infection. What is the appropriate approach to the evaluation and treatment of clostridial gas gangrene or myonecrosis? Patients without a preceding history of VZV exposure are at signicant risk of developing severe chickenpox if exposed, but herpes zoster (also known as shingles) with or without dissemination is a more frequent clinical concern. The development of fever during treatment-associated neutropenia is common, but many patients do not have an infectious etiology determined [184, 194]. Most resolve without any treatment. © The Author(s) 2020. The term “fasciitis” sometimes leads to the mistaken impression that the muscular fascia or aponeurosis is involved, but in fact it is the superficial fascia that is most commonly involved. White blood cell counts are generally normal, but mild leukocytosis can occur. Painful myositis can develop as a consequence of hematogenous infection and is most common with Candida tropicalis [218, 219]. Dermatologic manifestations vary from multiple erythematous macules to maculopapular lesions. Muscle inflammation and abscess formation are readily noted; other sites of infection such as osteomyelitis or septic arthritis may also be observed or a venous thrombosis detected [130, 131]. Erythroderma occurs early and desquamation occurs late. The benefits of regular tetanus toxoid boosters in adults who have had a primary series have been questioned although its use in “dirty wounds” seems sensible [161, 162]. Humans become accidental hosts either by inhalation or skin contact. Holland TL, Arnold C, Fowler VG Jr. Liu C, Bayer A, Cosgrove SE, et al. Biting flies occasionally transmit the illness in the United States, while mosquitoes are common vectors in Europe. Finally, while PET-CT may be a potentially promising adjunctive modality for the diagnosis of complicated Staphylococcus aureus bacteremia (SAB), its high cost prohibits its routine use in the United States. Superficial cutaneous candidiasis presents as intertrigo, vaginitis, balanitis, perleche, and paronychia [215] and rarely causes dissemination. What Is Appropriate for the Evaluation and Treatment of Erysipelas and Cellulitis? Panel members were selected based on their clinical and research expertise on diverse SSTIs including infections in compromised hosts, necrotizing fasciitis, gas gangrene, cellulitis, and cutaneous abscesses and infections following surgery and animal and human bites. Cutaneous cryptococcal infections may appear as papules (often similar to molluscum contagiosum lesions), nodules, pustules, chronic draining necrotic ulcers, or, more subtly, as cellulitis [235]. After considering the important specific factors concerning the patient's immunocompromised status (eg, neutropenia or neutrophil defects, cellular immune defect, presence of intravascular catheters) [180, 181], the gross morphologic characteristics of the skin lesion(s) should be characterized, the extent of the infection determined (eg, localized vs disseminated), and appropriate diagnostic tests undertaken to identify the infecting pathogen. What Is the Appropriate Approach to Assess SSTIs in Patients With Cellular Immunodeficiency? Therefore, this section of the SSTI guideline will focus on existing recommendations that demand reinforcement, or that are truly specific to SSTIs. Features suggestive of necrotizing fasciitis include (1) the clinical findings described above; (2) failure of apparently uncomplicated cellulitis to respond to antibiotics after a reasonable trial; (3) profound toxicity; fever, hypotension, or advancement of the SSTI during antibiotic therapy; (4) skin necrosis with easy dissection along the fascia by a blunt instrument; or (5) presence of gas in the soft tissues. When appropriate, the panel will recommend revision of the guideline to the SPGC and IDSA board and other collaborating organizations for review and approval. What Is the Preferred Evaluation and Treatment of Necrotizing Fasciitis, Including Fournier Gangrene? Excellent results have been reported for gram-negative infections using broad-spectrum monotherapy with carbapenems, cephalosporins that possess antipseudomonal activity, or piperacillin/tazobactam. This leaves the modern clinician with an unconfirmed diagnosis 80% of the time. Recently, resistance of S. aureus to methicillin, erythromycin, clindamycin, tetracycline, and SMX-TMP has dramatically increased and resistance of streptococci to erythromycin and clindamycin has been reported as well. The median duration of treatment was 10 (IQR, 5–15) days. have no conflicts to report. Thus clinicians should have a very low threshold to obtain a skin biopsy (Table 6). The Infectious Diseases Society of America 1, (IDSA) guidelines for the treatment of methicillin-resistant RESULTS S aureus (MRSA) bacteremia recommend vancomycin therapy for up to 6 weeks, depending on the source and clinical response [3]. Financial support. Holland TL, Raad I, Boucher HW, et al. Lesions begin as vesicles that rupture, resulting in circular, erythematous ulcers with adherent crusts, often with surrounding erythematous edema. Prompt administration of amphotericin B therapy is the recommended treatment for patients with cellular immune deciency and acute, life-threatening, progressive disseminated histoplasmosis. Cutaneous Nocardia infections usually represent metastatic foci of infection that have originated from a primary pulmonary source [230]. The use of newer molecular methods (eg, gene amplification and sequencing) will likely impact the management algorithms of immunocompromised patients with skin and soft tissue lesions and result in the earlier use of pathogen-directed antimicrobial therapy [184, 185]. D.H.T. Although no data exist, treatment with a parenteral agent until the acute illness is controlled, followed by an oral agent, seems rational for the duration of 7–10 days. A post-hoc analysis of three cohort studies, Gastrointestinal Histoplasmosis Mimicking Crohn’s Disease, Volume 8, Issue 5, May 2021 (In Progress), About the Infectious Diseases Society of America, http://creativecommons.org/licenses/by-nc-nd/4.0/, Receive exclusive offers and updates from Oxford Academic, Treatment Duration and Associated Outcomes for Skin and Soft Tissue Infections in Patients With Obesity or Heart Failure, No Clinical Benefit to Treating Male Urinary Tract Infection Longer Than Seven Days: An Outpatient Database Study. Anecdotal reports of infection following closure suggest against closure, although approximation may be acceptable [165]. Should skin lesions suspicious of VZV or HSV develop in patients already taking such antivirals, antiviral resistance should be investigated and taken into account in the selection of the empiric regimen. Epidermoid (or epidermal inclusion) cysts, often erroneously labeled sebaceous cysts, ordinarily contain skin flora in a cheesy keratinous material. The priorities for further research are as follows: The expert panel expresses its gratitude to the external reviewers, Drs. As it progresses, there is systemic toxicity, often including high temperatures, disorientation, and lethargy. Since the optimal antibiotic treatment duration in patients with uncomplicated SAB is often debated, we compliment the authors with examining this important research question. Until susceptibilities are available, ciprofloxacin is rational empiric therapy for bioterrorism-related cases. We hypothesized that the following factors may influence this decision: age, oxacillin sensitivity, community onset (SAB within 48 hours of admission without clear hospital acquisition), symptoms for ≥3 days before admission, catheter-associated deep vein thrombosis, immunosuppression (transplant recipients, active cancer, corticosteroid use, or use of other immunomodulatory agents), and significant valvular disease determined by echocardiography. Bubonic plague, the most common and classic form, develops when humans are bitten by infected fleas or have a breach in the skin when handling infected animals. Valvular disease, catheter-associated deep vein thrombosis, and immunosuppression were significantly associated with a planned antibiotic duration of >14 days (Table 2). Published Serological testing supports the diagnosis, although there is cross-reactivity between B. henselae and B. quintana as well as with a few other organisms. Untreated erysipeloid resolves over about 3–4 weeks, but treatment probably hastens healing and may reduce systemic complications. In patients with disseminated S. aureus infection, multiple small areas of pyomyositis may become apparent. In Which Patients Is Primary Wound Closure Appropriate for Animal Bite Wounds? The glandular varieties are generally acquired by handling infected animals, by tick bites, and sometimes by animal bites, especially cats. Studies in animal models demonstrate little efficacy of HBO when used alone, whereas antibiotics alone, especially those that inhibit bacterial protein synthesis, have marked benefit [139]. Ecthyma gangrenosum is a cutaneous vasculitis caused by invasion of the media and adventitia of the vessel wall by bacteria, which may be visible on histologic stains of biopsy specimens. XXIV. These infections can rapidly progress and involve deeper structures than just the skin, such as fascia, fat, or muscle (Tables 3 and 4). A distinguishing clinical feature is the wooden-hard induration of the subcutaneous tissues. For this reason, skin biopsy material should be obtained by an experienced dermatologist and evaluated in conjunction with a pathologist who is familiar with this patient population. Superficial incisional SSIs involve only the subcutaneous space, between the skin and underlying muscular fascia, occur within 30 days of the surgery, and are documented with at least 1 of the following: (1) purulent incisional drainage, (2) positive culture of aseptically obtained fluid or tissue from the superficial wound, (3) local signs and symptoms of pain or tenderness, swelling, and erythema after the incision is opened by the surgeon (unless culture negative), or (4) diagnosis of SSI by the attending surgeon or physician based on their experience and expert opinion. Computed tomography (CT) or magnetic resonance imaging (MRI) may show edema extending along the fascial plane, although the sensitivity and specificity of these imaging studies are ill defined. However, features that suggest involvement of deeper tissues include (1) severe pain that seems disproportional to the clinical findings; (2) failure to respond to initial antibiotic therapy; (3) the hard, wooden feel of the subcutaneous tissue, extending beyond the area of apparent skin involvement; (4) systemic toxicity, often with altered mental status; (5) edema or tenderness extending beyond the cutaneous erythema; (6) crepitus, indicating gas in the tissues; (7) bullous lesions; and (8) skin necrosis or ecchymoses. Despite an increased prevalence of gram-positive bacteria, antibiotics specifically aimed against this group of organisms are not required [187, 189] unless patients exhibit physical findings of SSTI or catheter-associated infection or are hemodynamically unstable [204]. The laboratory should be notified when tularemia is suspected because of the health risks posed to laboratory personnel. IX. A randomized trial comparing incision and drainage of cutaneous abscesses to ultrasonographically guided needle aspiration of the abscesses showed that aspiration was successful in only 25% of cases overall and <10% with MRSA infections [20]. Some clinicians close the wound with sutures or pack it with gauze or other absorbent material. Staphylococcus aureus is one of the most frequently identified bacteremia pathogens. Guidelines for the treatment of … Staphylococcus aureus accounts for about 90% of pathogens causing pyomyositis; community-acquired MRSA isolates in this infection have been reported in many nontropical communities [124–126]. What is the appropriate antibiotic therapy for patients with SSTIs during the initial episode of fever and neutropenia? Additionally, our study was limited by the number of patients excluded because they were lost to follow-up (48/612), which may have introduced bias if specific clinical features or comorbidities were disproportionately represented in this group. White blood cells may not be evident in the drainage in most clostridial and some early streptococcal infections. IDSA guidelines for the diagnosis and management of intravascular catheter-related bloodstream infection Clin Infect Dis . Examination of the local site typically reveals cutaneous inflammation, edema, and discoloration or gangrene and anesthesia. Further studies are needed to determine whether intravenous therapy given for >14 days is beneficial in specific cases of SAB that have historically been defined as uncomplicated but have features that may confer a higher risk for treatment failure. Definitive guidelines for treatment of these entities have been published [229]. One observational study demonstrated better outcomes in patients receiving IVIG, but this report was confounded because IVIG recipients were more likely to have had surgery and to have received clindamycin than the historical controls [119]. Direct needle aspiration of an area of cutaneous inflammation may yield fluid for Gram stain and culture. This is an Open Access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs licence (, Daniel Taupin, Adolf W Karchmer, Roger B Davis, Mary T LaSalvia. The panel's recommendations were developed to be concordant with the recently published IDSA guidelines for the treatment of methicillin-resistant Staphylococcus aureus infections. Nearly 50% of patients with necrotizing fasciitis caused by S. pyogenes have no portal of entry but develop deep infection at the exact site of nonpenetrating trauma such as a bruise or muscle strain. Clinical data for a role of HBO are very poor quality and are entirely based on uncontrolled, observational case series [142]. HBO is advocated on the basis of laboratory studies showing that it suppressed log-phase growth of C. perfringens, but not the more aerotolerant C. septicum [140, 141]. XIV. Herpes zoster occurs most frequently during the rst year following chemotherapy treatment, or following receipt of an HSCT or a SOT. Since then, a few patients have been received fluoroquinolones. bacteremia? The incidence of local and disseminated Nocardia infections has decreased with the routine use of SMX-TMP prophylaxis for patients who experience prolonged periods of cellular immune deciency. However, we have several concerns with regard to the design of this study and the interpretation of results. A booster dose of tetanus toxoid vaccine should be administered for dirty wounds if >5 years has elapsed since the last dose and for clean wounds, if >10 years. XI. V. Should Anti-inflammatory Agents Be Used to Complement Antibiotic Treatment of Cellulitis? Painful myositis may also occur with S. aureus infections as a component of hematogenous dissemination. Eighty percent of patients have significant underlying diseases, particularly diabetes mellitus. Most bacteremia stemmed from the GU (594 patients, 40.2 percent) or gastrointestinal tract (297, 20.1 percent), or was central line-associated (272, 18.4 percent). In cellulitis, the subcutaneous tissues are palpable and yielding; in fasciitis the underlying tissues are firm, and the fascial planes and muscle groups cannot be discerned by palpation. Pyogenic Arthritis of the Fingers and the Wrist: Can We Shorten Antimicrobial Treatment Duration? Cefazolin or antistaphylococcal penicillin is recommended for definitive therapy of pyomyositis caused by MSSA. For adults, the regimen for streptomycin is 30 mg/kg/day in 2 divided doses (no more than 2 g daily) or gentamicin 1.5 mg/kg every 8 hours, with appropriate dose adjustment based on renal function. For oral regimens, patients should receive at least 14 days of therapy. VZV in compromised hosts may present with the traditional unilateral dermatome distribution, but may also appear as discrete or multiple skin lesions in random distribution. The primary outcome was treatment failure at 90 days after hospital discharge, which was defined as diagnosis of a complicated staphylococcal infection after discharge, change in treatment because of unsatisfactory clinical response, death due to SA infection (determined by chart review), or relapsed infection. Oxford University Press is a department of the University of Oxford. The duration of therapy may range from two to six weeks depending on the A blue ring with a peripheral red halo may appear, giving the lesion a target appearance. von Dach E, Albrich WC, Brunel AS, et al. (%), Catheter-associated adverse event, No. In a survey of >700 practicing infectious disease physicians in the United States and Canada, 48% of respondents indicated that they would extend the duration of antibiotics for SAB from 2 weeks to 4–6 weeks if the patient had an immunocompromising condition [5]. Early surgical inspection and debridement are necessary, and tissue Gram stain shows large, gram-positive or gram-variable rods at the site of infection [136]. Østergaard L, Valeur N, Wang A, et al. The following 25 clinical questions are answered: “Practice guidelines are systematically developed statements to assist practitioners and patients in making decisions about appropriate health care for specific clinical circumstances” [8]. A.W.K. The optimal duration of treatment is uncertain, but 7–10 days appears adequate in naturally acquired cases. Our definition of failure, including only SAB-related mortality, may more accurately reflect the true incidence of antibiotic failure. A few patients present initially with disseminated cutaneous infection that may mimic atypical varicella, but some patients may present with nonspecific lesions that do not initially have the vesicular appearance of varicella. Endogenous pathogens can be largely restricted to S. aureus or streptococcal species such as groups A, B, C, or G, and together these account for the vast majority of SSTIs. Clinically, furuncles are inflammatory nodules with overlying pustules through which hair emerges. Examples would include postoperative peritonitis, empyema, or joint space infection. Three plague syndromes occur in humans: septicemic, pneumonic, and bubonic. Panel members were provided IDSA's conflicts of interest disclosure statement and were asked to identify ties to companies developing products that might be affected by promulgation of the guideline. Last, surgical exploration or debridement is an important diagnostic, as well as therapeutic, procedure in patients with necrotizing infections or myonecrosis and may be important for selected immunocompromised hosts. Additionally, nonpurulent wound infections may also be polymicrobial [156]. Cutaneous mold infections have been increasingly reported in immunocompromised patients with primarily cellular immunodeficiency. Although gram-positive bacteria are more common, the addition of antibiotics with gram-positive activity including MRSA is not recommended unless physical findings suggestive of inflammation in the skin and soft tissues are present, the patient is hemodynamically unstable, and risk factors for MRSA are present. Infections following surgical operations on the axilla also have a significant recovery of gram-negative organisms, and those in the perineum have a higher incidence of gram-negative organisms and anaerobes [100, 103, 104]; antibiotic selections should provide coverage for these organisms (Table 3). Current definitions of uncomplicated bacteremia do not address these factors. Eikenella corrodens is resistant to first-generation cephalosporins, macrolides, clindamycin, and aminoglycosides (Table 5). Extensive undermining of surrounding tissues is usually present, and the tissue planes can be readily dissected with a gloved finger or a blunt instrument. Plague results from infection with Yersinia pestis, a facultative anaerobic gram-negative coccobacillus. This practice guideline provides recommendations for the diagnosis and management of skin and soft tissue infections (SSTIs) in otherwise healthy hosts and compromised hosts of all age groups. First, we would like to address their questions about the diagnostic workup of included patients. A careful epidemiologic history (eg, exposure to raw seafood, pets, and travel) should also be obtained in these patients to consider organisms potentially associated with these exposures when appropriate (eg, V. vulnificus, B. henselae, cutaneous leishmaniasis). Prospective studies evaluating the yield of skin biopsy or aspiration have not been performed in adult immunocompromised patients, but most clinicians who manage these patients combine blood cultures, serial antigen detection, nucleic acid amplification techniques, radiographic imaging, and a biopsy or aspiration of the abnormal skin or soft tissue lesion in the hope of increasing the recovery of the offending pathogen and directing pathogen-specific antimicrobial therapy. As with other necrotizing infections, prompt, aggressive surgical debridement is necessary to remove all necrotic tissue, sparing the deeper structures when possible. However, systemic antibiotics should be given to patients with severely impaired host defenses or signs or symptoms of systemic infection (Figure 1, Table 2). Signs of clinical instability: oxygen saturation < 90% or new oxygen requirement, heart rate > 100 Footnotes In addition, multiple abscesses, extremes of age, and lack of response to incision and drainage alone are additional settings in which systemic antimicrobial therapy should be considered. Skin biopsy should be performed for diagnostic purposes and resection of the entire lesion or “debulking” procedures should be considered in cases where there is either a single lesion or localized disease is present. The risk for PNSP bacteremia among patients with either 1 or ⩾2 treatment courses compared with patients without previous antibiotic use is shown in table 5 . Fournier gangrene usually occurs from a perianal or retroperitoneal infection that has spread along fascial planes to the genitalia; a urinary tract infection, most commonly secondary to a urethral stricture, that involves the periurethral glands and extends into the penis and scrotum; or previous trauma to the genital area, providing access of organisms to the subcutaneous tissues. XXIII. This should include the respective roles of toxins and host response molecules in the genesis of redness, swelling, pain, and edema. The single published trial of antibiotic administration for SSI specifically found no clinical benefit [99]. Should tetanus toxoid be administered for animal bite wounds? Oral linezolid was considered an intravenous equivalent. Isolation of Aspergillus from blood cultures is rare, but dissemination is commonly detected at autopsy [224]. Patients with bubonic plague may develop septicemia and secondary plague pneumonia, which is transmissible person-to-person. Discrepancies were discussed and resolved, and all panel members are in agreement with the final recommendations. Its value seems to be primarily in reducing mortality from as high as 20% to zero. Daniel Taupin, Adolf W Karchmer, Roger B Davis, Mary T LaSalvia, Uncomplicated Staphylococcus aureus Bacteremia Treatment Duration and Outcomes at an Academic Medical Center, Open Forum Infectious Diseases, Volume 7, Issue 10, October 2020, ofaa457, https://doi.org/10.1093/ofid/ofaa457. The infection may extend to the perineum and the anterior abdominal wall. Cephalosporins, clindamycin, or fluoroquinolones should be effective for those intolerant of penicillin. Signs of systemic toxicity, including tachycardia, fever, and diaphoresis, develop rapidly, followed by shock and multiple organ failure.
