Belinchón-Romero I, Merino E, Ramos-Rincón JM. Sex differences in clinical characteristics and outcomes in patients hospitalized with cellulitis in Spain (2016-2022). Int J Infect Dis 2025; 154:107846. [PMID: 39961451 DOI: 10.1016/j.ijid.2025.107846] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2025] [Revised: 02/09/2025] [Accepted: 02/13/2025] [Indexed: 03/18/2025] Open
Abstract
PURPOSE To estimate hospitalization rates, analyze sex-specific clinical characteristics, assess in-hospital mortality and its risk factors, and measure the economic burden of cellulitis hospitalizations. MATERIALS AND METHODS This retrospective population-based study included adults aged ≥15 years hospitalized for cellulitis in Spain from 2016 to 2022. Multivariable logistic regression was used to identify factors associated with in-hospital mortality (IHM). RESULTS A total of 194,673 cellulitis hospitalizations were recorded (90,828 women and 103,845 men). The mean hospitalization rates per 1000 admissions and per 100,000 inhabitants were lower in women than men (6.0 vs. 7.6 and 63 vs. 76, respectively). In women, cellulitis was more common in those aged 65-75 and ≥80 years and in those with hypertension, dyslipidemia, heart failure, or hypothyroidism. Women had a higher crude IHM (7.4%) than men (5.9%), but sex was not significantly associated with mortality after adjustment (AOR: 1.02; 95% CI: 0.93-1.07). The strongest predictors of mortality were similar in both women and men. These included leukemia (AOR: 4.45 vs. 3.15), age ≥80 years (AOR: 3.96 vs. 4.39), sepsis (AOR: 3.59 vs. 2.95), neoplasia (AOR: 3.44 vs. 3.47), and cirrhosis (AOR: 2.49 vs. 2.41). The total hospitalization cost for women was €451.8 million, with a median cost of €3,653 per admission. CONCLUSIONS The clinical profile and outcomes of cellulitis differ by sex. In women, advanced age, comorbidities, and complications like sepsis significantly increased mortality risk.

Abstract
Objectives: Pathogenic organisms utilize iron to survive and replicate and have evolved many processes to extract iron from human hosts. The goal of this study was to elucidate the impact of iron supplementation given in the setting of acute infection. Methods: This was a retrospective cohort study of Veterans Affairs patients who received intravenous antibiotics for pneumonia or skin and skin structure infections. Five-thousand subjects were included in each of the 2 cohorts: iron-receiving and non-iron-receiving. Data was analyzed using Fischer's Exact test if categorical and independent t-tests if continuous. Primary and secondary objectives analyzed with Cox proportional hazard regression and outcome rates estimated utilizing Kaplan-Meier method. Results: Five-thousand patients were included in each cohort. The iron cohort was significantly older (Mean-years: Iron = 71.6, No-iron = 68.9; mean-difference = 2.7, P < .0001) with reduced renal function (Mean-eGFR[mL/min/1.73 m²]: Iron = 67.2, No-iron = 77.4; mean-difference = 10.2, P < .0001). For the primary outcome, the iron cohort had a significantly longer mean length of hospital stay (10.4 days) compared to the no-iron cohort (8.7 days) (mean difference 1.7 days, P < .0001). Secondary outcome analysis showed the iron cohort received intravenous antibiotics for longer (Iron = 8.2 days, No-iron = 7.1 days; mean-difference = 1.1 days, P < .0001) with a higher proportion of 30-day readmissions (Iron = 15.6%, No-iron = 12.8%; proportion difference = 2.8%, P < .0001). No significant difference was found between cohort proportions for 30-day mortality (Iron = 12.7%, No-iron = 11.3%, proportion difference = 1.4%, P = .052). Conclusions: Baseline characteristic differences between cohorts is representative of patients who would be expected to require iron replacement therapy. Given the magnitude of primary and secondary-outcomes, further studies controlling for these factors would be warranted.

Abstract
BACKGROUND AND OBJECTIVE The burden of nonvenereal infections in Spanish dermatology practice has not yet been evaluated. The aim of this study was to analyze the overall weight of these infections in outpatient dermatology caseloads. MATERIAL AND METHODS Observational cross-sectional study of diagnoses made by a random selection of dermatologists from the Spanish Association of Dermatology and Venereology (AEDV) working in outpatient dermatology clinics. The data were obtained through the anonymous DIADERM survey. Diagnoses of infectious diseases were selected using codes from the International Classification of Diseases, Tenth Revision. After excluding sexually transmitted infections, the diagnoses were classified into 22 groups. RESULTS Spanish dermatologists diagnosed an estimated 16Y190 (95% CI, 9338-23Y042) nonvenereal infections on average per week, a figure that accounted for 9.33% of the dermatology caseload. The most common diagnostic groups were nonanogenital viral warts (7475 diagnoses, 46.17% of nonvenereal infections), dermatophytosis (3336, 20.61%), and other viral infections (1592, 9.84%), which included Molluscum contagiosum infections. Nonvenereal infections were more common than noninfectious dermatologic conditions in private clinics (P<.0020) and adults (P<.00001). Patients with these infections were also more likely to be discharged than those with other conditions in both public (P<.0004) and private (P<.0002) practices. CONCLUSIONS Nonvenereal infections are frequent in dermatology. They are the third most common reason for outpatient visits, behind actinic keratosis and nonmelanoma skin cancer. By enhancing the participation of dermatologists in the management of skin infections and encouraging interactions with other specialists, we will be able to carve out a niche in an area we have scarcely ventured into to date.

Abstract
Background: Skin and soft tissue infections are one of the main causes of consultations worldwide. The objective was to determine the treatment of a group of patients with uncomplicated skin and soft tissue infections in Colombia. Methods: Follow-up study of a cohort of patients with skin infections who were treated in the Colombian Health System. Sociodemographic, clinical and pharmacological variables were identified. Treatments were evaluated using clinical practice guidelines for skin infections. Results: A total of 400 patients were analyzed. They had a median age of 38.0 years and 52.3% were men. The most commonly used antibiotics were cephalexin (39.0%), dicloxacillin (28.0%) and clindamycin (18.0%). A total of 49.8% of the subjects received inappropriate antibiotics, especially those with purulent infections (82.0%). Being cared for in an outpatient clinic (OR: 2.09; 95% CI: 1.06-4.12), presenting pain (OR: 3.72; 95% CI: 1.41-9.78) and having a purulent infection (OR: 25.71; 95% CI: 14.52-45.52) were associated with a higher probability of receiving inappropriate antibiotics. Conclusions: Half of patients with uncomplicated skin and soft tissue infections were treated with antibiotics that were not recommended by clinical practice guidelines. This inappropriate use of antibiotics occurred in the vast majority of patients with purulent infections because the antimicrobials used had no effect on methicillin-resistant Staphylococcus aureus.

Antibiotics (Basel) 2023; 12:antibiotics12020275. [PMID: 36830186 PMCID: PMC9951966 DOI: 10.3390/antibiotics12020275] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 01/24/2023] [Accepted: 01/26/2023] [Indexed: 02/04/2023] Open
Abstract
Skin and soft tissue infections (SSTIs) are one of the most common infectious diseases requiring antibiotics. However, complications of SSTIs may lead to the overprescribing of antibiotics and to subsequent antibiotic resistance. Consequently, monitoring the prescribing alignment with the current recommendations from the South African Standard Treatment Guidelines (STG) is necessary in order to improve future care. This study involved reviewing pertinent patients with SSTIs who were prescribed antimicrobials in the surgical ward of a leading South African tertiary public hospital from April to June 2021 using an adapted data collection tool. Sixty-seven patient files were reviewed. Among the patients with SSTIs, hypertension and chronic osteomyelitis were the most frequent co-morbidities at 22.4% and 13.4%, respectively. The most diagnosed SSTIs were surgical site infections (35.1%), wound site infections (23%), and major abscesses (16.2%). Blood cultures were performed on 40.3% of patients, with Staphylococcus aureus (32.7%) and Enterococcus spp. (21.2%) being the most cultured pathogens. Cefazolin was prescribed empirically for 46.3% of patients for their SSTIs. In addition, SSTIs were treated with gentamycin, ciprofloxacin, and rifampicin at 17.5%, 11.3%, and 8.8%, respectively, with treatment fully complying with STG recommendations in 55.2% of cases. Overall, the most common cause of SSTIs was Staphylococcus aureus, and empiric treatment is recommended as the initial management. Subsequently, culture sensitivities should be performed to enhance adherence to STGs and to improve future care.

Crit Care 2022; 26:371. [PMID: 36447252 PMCID: PMC9710072 DOI: 10.1186/s13054-022-04212-9] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 10/15/2022] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND Sepsis is a complex health condition, leading to long-term morbidity and mortality. Understanding the risk factors for recurrent sepsis, as well as its impact on mid- and long-term mortality among other risk factors, is essential to improve patient survival. METHODS A risk factor analysis, based on French nationwide medico-administrative data, was conducted on a cohort of patients above 15 years old, hospitalized with an incident sepsis in metropolitan France between 1st January 2018 and 31st December 2018 and who survived their index hospitalization. Two main analyses, focusing on outcomes occurring 1-year post-discharge, were conducted: a first one to assess risk factors for recurrent sepsis and a second to assess risk factors for mortality. RESULTS Of the 178017 patients surviving an incident sepsis episode in 2018 and included in this study, 22.3% died during the 1-year period from discharge and 73.8% had at least one hospital readmission in acute care, among which 18.1% were associated with recurrent sepsis. Patients aged between 56 and 75, patients with cancer and renal disease, with a long index hospital stay or with mediastinal or cardiac infection had the highest odds of recurrent sepsis. One-year mortality was higher for patients with hospital readmission for recurrent sepsis (aOR 2.93; 99% CI 2.78-3.09). Among all comorbidities, patients with cancer (aOR 4.35; 99% CI 4.19-4.52) and dementia (aOR 2.02; 99% CI 1.90-2.15) had the highest odds of 1-year mortality. CONCLUSION Hospital readmission for recurrent sepsis is one of the most important risk factors for 1-year mortality of septic patients, along with age and comorbidities. Our study suggests that recurrent sepsis, as well as modifiable or non-modifiable other risk factors identified, should be considered in order to improve patient care pathway and survival.

Abstract
PURPOSE OF REVIEW Skin and soft tissue infections (SSTIs) are a leading cause of morbidity, emergency department visits and hospitalization. In recent years, the spread of carbapenem-resistant gram-negative bacteria (GNB) is also increasing in SSTIs. However, the armamentarium of available drugs is recently expanding as well. In this review, we reported the most recent data and about management and treatment of SSTIs caused by GNB, mainly for the treatment of carbapenem-resistant Enterobacterales (CRE), Pseudomonas spp and Acinetobacter spp. RECENT FINDINGS The increasing incidence of carbapenem-resistant GNB is challenging for management and treatment, considering the high rate of inappropriate empiric and targeted antimicrobial treatments. The role of new antibiotics, mainly licensed for the treatment of other infections, is an object of continuous debate. As a matter of fact, no specific clinical trials on SSTIs have been performed for new drugs; however, recent data about the use in real life of new compounds in clinical practice are available. SUMMARY Some recently approved drugs are actually considered the backbone of targeted therapy in patients with severe infections caused by susceptible carbapenem-resistant GNB strains. Prompt diagnosis of cSSTIs is crucial and, when necessary, surgical debridement for source control of infection is the milestone of the treatment. The physicians should be confident to identify patients at high risk for multidrug-resistant pathogens to minimize inappropriate empiric therapy.

Abstract
PURPOSE OF REVIEW Skin and soft tissue infections (SSTIs) are among the most common infections in outpatients and the most frequent infectious cause of referrals to emergency departments in developed world, contributing to significant morbidity and healthcare expenditures. We sought to review recent literature covering epidemiology of SSTIs. RECENT FINDINGS Staphylococcus aureus and streptococci predominate and methicillin-resistant S. aureus (MRSA) poses additional challenges; community-acquired-MRSA in some areas is superseding methicillin-susceptible S. aureus and multidrug resistance is evolving. Incidence data of SSTIs from United States show a decreasing trend, whereas trends of hospitalization rates were increasing. Despite low mortality associated with SSTIs, high rates of treatment failure and relapses are of concern. Diagnosis and management decisions in the emergency department (ED) lack validated tools for prediction of clinical response particularly among elderly, immunocompromised, obese, and patients with comorbidities. A variety of modifiable and nonmodifiable risk factors of the host and data from local epidemiology should be considered to prevent recurrence and treatment failure. SUMMARY An evolving epidemiology of SSTIs make microbiologic documentation and surveillance of local data imperative. New assessment algorithms with potential use in the ED are a priority. The universal applicability of international guidelines is questioned in this setting.

Abstract
INTRODUCTION Methicillin-resistant Staphylococcus aureus (MRSA) is among the most frequent causative agents of acute bacterial skin and skin-structure infections (ABSSSI) and has been associated with increased risks of invasive disease and of treatment failure. AREAS COVERED In this review, we focus on those novel anti-MRSA agents currently in phase I or II of clinical development that may enrich the armamentarium against ABSSSI caused by MRSA in the future. EXPERT OPINION Promising agents belonging to either old or novel antibiotic classes are currently in early phases of clinical development and may become available in the future for the effective treatment of ABSSSI caused by MRSA. In particular, the future availability of agents belonging to novel classes will be important for guaranteeing an effective treatment and for allowing outpatient treatment/early discharge, with a consequent reduced impact on healthcare resources. However, this does not mean that we can relax our efforts directed toward improving the responsible use of already available agents. Indeed, preserving their activity in the long term is crucial for optimizing the use of healthcare resources.

Abstract
BACKGROUND Antibiotic resistance has become a global threat for human health, calling for rational use of antibiotics.
AIM To analyze the distribution and drug resistance of the bacteria, providing the prerequisite for use of antibiotics in emergency patients.
METHODS A total of 2048 emergency patients from 2013 to 2017 were enrolled. Their clinical examination specimens were collected, followed by isolation of bacteria. The bacterial identification and drug susceptibility testing were carried out.
RESULTS A total of 3387 pathogens were isolated. The top six pathogens were Acinetobacter baumannii (660 strains), Staphylococcus aureus (436 strains), Klebsiella pneumoniae (347 strains), Pseudomonas aeruginosa (338 strains), Escherichia coli (237 strains), and Candida albicans (207 strains). The isolation rates of these pathogens decreased year by year except Klebsiella pneumoniae, which increased from 7.1% to 12.1%. Acinetobacter baumannii is a widely-resistant strain, with multiple resistances to imipenem, ciprofloxacin, minocycline and tigecycline. The Staphylococcus aureus had high resistance rates to levofloxacin, penicillin G, and tetracycline. But the susceptibility of it to vancomycin and tigecycline were 100%. Klebsiella pneumoniae had high resistance rates to imipenem, cefoperazone/sulbactam, amikacin, and ciprofloxacin, with the lowest resistance rate to tigecycline. The resistance rates of Pseudomonas aeruginosa to cefoperazone/sulbactam and imipenem were higher, with the resistance rate to amikacin below 10%. Besides, Escherichia coli had high resistance rates to ciprofloxacin and cefoperazone/sulbactam and low resistance rates to imipenem, amikacin, and tigecycline.
CONCLUSION The pathogenic bacteria isolated from the emergency patients were mainly Acinetobacter baumannii, Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans. The detection rates of drug-resistant bacteria were high, with different bacteria having multiple drug resistances to commonly used antimicrobial agents, guiding the rational use of drugs and reducing the production of multidrug-resistant bacteria.

Risk factors associated with methicillin-resistant Staphylococcus aureus skin and soft tissue infections in hospitalized patients in Colombia. Int J Infect Dis 2019; 87:60-66. [PMID: 31330321 DOI: 10.1016/j.ijid.2019.07.007] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 07/09/2019] [Accepted: 07/13/2019] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVES Methicillin-resistant Staphylococcus aureus (MRSA) skin and soft tissue infections (SSTIs) represent a major clinical problem in Colombia. The aim of this study was to evaluate the risk factors associated with MRSA SSTI in Colombia. METHODS A multicenter cohort study with nested case-control design was performed. Patients with an SSTI with at least 48h of inpatient care were included. Patients with an MRSA SSTI were considered the case group and patients with either a non-MRSA SSTI or with an Methicillin-susceptible S. aureus (MSSA) SSTI were the control groups. A multivariate logistic regression approach was used to evaluate risk factors associated with MRSA SSTI with two different statistical models. RESULTS A total 1134 patients were included. Cultures were positive for 498 patients, of which 52% (n=259) were Staphylococcus aureus. MRSA was confirmed in 68.3% of the S. aureus cultures. In the first model, independent risk factors for MRSA SSTI were identified as the presence of abscess (P<0.0001), cellulitis (P=0.0007), age 18-44 years (P=0.001), and previous outpatient treatment in the previous index visit (P=0.003); surgical site infection was a protective factor (P=0.008). In the second model, the main risk factor found was previous outpatient treatment in the previous index visit (P=0.013). CONCLUSIONS Community-acquired SSTIs in Colombia are commonly caused by MRSA. Therefore, clinicians should consider MRSA when designing the initial empirical treatment for purulent SSTI in Colombia, although there seems to be low awareness of this fact.

Etiology, characteristics, and outcomes of community-onset necrotizing fasciitis in Korea: A multicenter study. PLoS One 2019; 14:e0218668. [PMID: 31220158 PMCID: PMC6586320 DOI: 10.1371/journal.pone.0218668] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2018] [Accepted: 06/06/2019] [Indexed: 12/12/2022] Open
Abstract
Background Necrotizing fasciitis (NF) is a serious skin and soft tissue infection causing high mortality. Investigating region specific epidemiologic factors associated with NF is important for establishing appropriate treatment strategies. This multicenter study was done to provide an update of the microbial etiology, clinical characteristics, and outcomes of NF in Korea. Materials and methods A retrospective cohort of adult patients with NF was established using patient data from 13 general hospitals between January 2012 and December 2015 in Korea. We evaluated microbial etiology and clinical characteristics to identify risk factors associated with in-hospital mortality; analyses were performed using binary logistic regression models. Results A total of 161 patients with NF were included. The most common underlying disease was diabetes mellitus (66 cases, 41.0%). A total of 148 organisms were isolated from 119 (73.9%) patients. Enteric Gram-negative organisms (36 patients) were the most common pathogen, followed by Staphylococcus aureus (30 patients) and streptococci (28 patients). Methicillin-resistant Staphylococcus aureus (MRSA) was identified in 6.2% (10/161) of patients. Of 37 enteric Gram-negative isolates tested, 26 (70.3%) isolates were susceptible to ceftriaxone. The in-hospital mortality rate was 22.4%. Intensive care unit admission, septic shock, and Gram-negative organism infections were significantly associated with in-hospital mortality, and surgery was not a favorable prognostic factor. Conclusions As initial empirical antibiotics, glycopeptides against MRSA and broad-spectrum antibiotics against third-generation cephalosporin-resistant organisms should be considered for patients with community-onset NF in Korea.

Abstract
BACKGROUND Skin and soft tissue infections (SSTIs) are a common cause of consultation, and complicated cases require hospitalization. We describe factors that are related to readmission and/or mortality of hospitalized patients diagnosed with SSTIs. METHODS Retrospective review of hospital-admitted patients with a diagnosis of cellulitis, abscess, hidradenitis, fasciitis, and Fournier's gangrene. Cases from January 2002 to October 2015 were extracted from the diagnostic codification database of the Archives and Clinical Documentation Department. FINDINGS We studied 1,482 episodes of hospitalized patients diagnosed with SSTIs. There were 187 (12.3%) readmissions, the most frequent diagnosis was cellulitis (72.7%), and the most commonly isolated microorganism was Staphylococcus aureus (25; 30.1%). Factors associated with readmissions were healthcare-related infections (P = 0.002), prior antibiotic therapy (P < 0.001), ischemic heart disease (P = 0.01), chronic liver disease (P = 0.001), and diabetes mellitus (DM) (P = 0.006). The number of patients who died as a result of an infection was 34 (2.2%) and, in these patients, the most common diagnosis was also cellulitis (79.4%), which in 52.9% (P = 0.001) was community acquired. DM (P = 0.01), heart failure (P = 0.001), and chronic liver disease (P = 0.003) were the most frequent comorbidities. This group presented more complications (P < 0.005) such as endocarditis (P < 0.005), amputation (P = 0.018), severe sepsis (P < 0.005), and septic shock (P < 0.001). CONCLUSIONS Readmitted patients had healthcare-related S. aureus infection, had received prior antibiotic therapy, and presented comorbid conditions such as ischemic heart disease, peripheral vascular disease, chronic liver disease, or DM. Comorbidities such as advanced age, DM, heart failure, and chronic liver disease were associated with complications and higher infection-related mortality.

Abstract
Over the last 25 years, the terminology of skin and soft tissue infections, as well as their classification for optimal management of patients, has changed. The so-called and recently introduced term 'acute bacterial skin and skin structure infections' (ABSSSIs), a cluster of fairly common types of infection, including abscesses, cellulitis, and wound infections, require an immediate effective antibacterial treatment as part of a timely and cautious management. The extreme level of resistance globally to many antibiotic drugs in the prevalent causative pathogens, the presence of risk factors of treatment failure, and the high epidemic of comorbidities (e.g. diabetes and obesity) make the appropriate selection of the antibiotic for physicians highly challenging. The selection of antibiotics is primarily empirical for ABSSSI patients which subsequently can be adjusted based on culture results, although rarely available in outpatient management. There is substantial evidence suggesting that inappropriate antibiotic treatment is given to approximately 20-25% of patients, potentially prolonging their hospital stay and increasing the risk of morbidity and mortality. The current review paper discusses the concerns related to the management of ABSSSI and the patient types who are most vulnerable to poor outcomes. It also highlights the key management time-points that treating physicians and surgeons must be aware of in order to achieve clinical success and to discharge patients from the hospital as early as possible.
