Abstract Inpatients with culture-positive diabetic foot infections are at elevated risk for subsequent invasive infection with the same causative organism. In outpatients with index diabetic foot ulcers, we found that wound culture positivity was independently associated with increased odds of 1-year admission for systemic infection when compared to culture-negative wounds.

abstractThe impact of preoperative antibiotics on culture of diabetic foot infection samples has not been studied. We found that increasing exposure to preoperative antibiotics was associated with less frequent growth of streptococci and anaerobes and more culture-negative results. In contrast, the yield of Staphylococcus aureus and Gram-negative bacilli was unaffected.

Diabetic foot infections are a common and serious problem for all health systems worldwide. The aim of this study was to examine the resistance to antibiotics of microorganisms isolated from infected soft tissues of diabetic foot ulcers, using tissue cultures. We included 113 consecutive patients (70 men, 43 women) with a mean age of 66.4 ± 11.2 years and a mean diabetes duration of 14.4 ± 7.6 years presenting with diabetic foot soft tissue infections. Generally, no high antibiotic resistance was observed. Piperacillin-tazobactam exhibited the lowest resistance in Pseudomonas, as well as in the other Gram-negative pathogens. In methicillin-resistant Staphylococcus aureus isolates, there was no resistance to anti-Staphylococcus agents. Of note, clindamycin, erythromycin, and amoxycillin/clavulanic acid exhibited high resistance in Gram-positive cocci. These results suggest that antibiotic resistance in infected diabetic foot ulcers in our area is not high and they are anticipated to prove potentially useful in the initial choice of antibiotic regimen.

BACKGROUND Diabetic foot is the most common and most feared complication of diabetes and is more significant than nephropathy, retinopathy, heart attack, and stroke combined. Diabetes-associated problems are the second common cause of lowerlimb amputations in India. Foot disorders like ulcerations, infection, Gangrene are the leading causes of hospitalization in patients with diabetes mellitus in India.1 METHODS A prospective study, carried out on 100 diabetic patients with foot ulcers over a period of one year from April 2019 to March 2020 at Sri Venkateswara Medical College hospital. The extent of foot infection was assessed based on Wagner’s classification and were studied based on the culture and sensitivity obtained and the efficacy of the antibiotic used. RESULTS The data analysis of 100 patients has given the following results. 70 % (70 patients) of them were culture positive, and 30 % (30 patients) were culture negative. Culture positive patients were divided into two groups with 35 patients each. Group A started on empirical therapy, Group B on sensitive antibiotic therapy. Repeat swab taken on day 7 from the previously culture-positive patients (70 patients), it was found that 30 out of 35 patients of group-A (empirical therapy) were still culture positive with a similar or newer organism, only 5 patients were culture negative, whereas in 35 patients of Group-B (sensitive antibiotic therapy) only 5 patients were culture positive with a similar or newer organism, remaining 30 patients were culture negative. Sensitive antibiotic therapy was found to be effective than empirical therapy in treatment of diabetic foot ulcers. CONCLUSIONS Culture and sensitivity from the wounds play a critical role in prescribing appropriate antibiotic at the time of admission itself rather than starting the empirical treatment.

Wound Myiasis

Background: Myiasis is a parasitic infestation of tissues or body cavities of mammals with dipterous larvae. The patients with diabetic foot ulcers are more vulnerable to acquiring infestation; however, the infestation may be neglected and mistreated in some cases.  Methods: Data were collected of twelve myiasis cases with diabetic foot ulcers in Nazli-Selim Eren Chronic Wound and Infections Care Unit, Aydin, Turkey between 2017 and 2019. Demographic, clinical characteristics of the patients and clinical examination of the wound were recorded. To morphology-based identification method of the agents, the developmental stages of the maggots were examined. Results: The cases aged between 46 and 81 years (10 males, two females). Eight of the larvae collected from wounds had Calliphoridae and four had Sarcophagidae family. The larvae were infested right/left foot sole, thumb, ankle, and mostly left toes. The number of larvae collected from the cases ranged from 2 to 48. Third-stage larvae (L3) were mostly detected. Mixed (L1-L2, L2-L3) larvae were detected in a patient. The infestations were more common in July and August. According to the score of Infectious Diseases Society of America (IDSA), ten (83%) cases had moderate and two (17%) cases were mild diabetic foot infections (DFIs). Conclusion: Diabetic foot ulcers should be evaluated in terms of myiasis. This was the first study in our province indicating that myiasis should not be neglected and different species of flies were responsible for myiasis cases.

Background: Diabetic foot infections can cause substantial morbidity. The role of Diabetes mellitus in the antimicrobial resistance of pathogens in patients with foot infections is not well clarified. So, we compared the profile of antibiotic resistance in diabetic and non-diabetic foot ulcer infections. Objectives were to compare the antimicrobial resistance pattern in diabetic and non-diabetic lower limb infections.Methods: T Pus was isolated in 50 Diabetic and 50 non-diabetic foot ulcer infections. The organisms were isolated on specific media and antibiotic susceptibility was done by using Kirby-Bauer disc diffusion method.Results: The most frequent causative organism in diabetic and non-diabetics is Pseudomonas 27.5% vs 27.1%, Staphylococcus 24.1% vs 27.1%, Klebsiella 24.1% vs 22.03%, E. coli 10.3% vs 10.16%, Proteus 5.17% vs 5.08%. No significant differences in resistance rates to Amikacin, Penicillin, Ofloxacin, Vancomycin, Piperacillin + Tazobactum were observed between diabetic and non-diabetic patients. There is significant difference in resistance to Ampicillin (p=0.017).Conclusions: Diabetes per se does not seem to influence the susceptibility pattern to antimicrobials in our group of patients with foot ulcer infections.

Abstract Purpose To compare the mortality rates between culture-positive and culture-negative sepsis in complicated intra-abdominal infections (cIAI) and investigate the predictors of culture-positivity and their causative microorganisms. Materials and methods The medical records of 1581 adult patients who underwent emergency gastrointestinal surgery between January 2013 and December 2018 were reviewed retrospectively. A total of 239 patients with sepsis or septic shock who were admitted to an emergency department, underwent emergency surgery for cIAI, and needed postoperative intensive care unit care were included and divided into two groups according to their initial blood and peritoneal culture results. Results Among the 239 patients, 200 were culture-negative and 39 were culture-positive. The culture-positive group had higher in-hospital (35.9% vs 14.5%; P = .001) and 30-day mortality (30.8% vs 12.0%; P = .003) than the culture-negative group. Colon involvement (OR 4.211; 95% CI 1.909–9.287; P < .001) and higher Sequential Organ Failure Assessment (SOFA) score (OR 1.169; 95% CI 1.065–1.282; P = .001) were shown to be the predictors of culture-positive sepsis for cIAI. Regarding antibiotic sensitivity, 31.6% of the gram-positive bacteria were methicillin-resistant and 42.1% of the gram-negative bacteria were extended spectrum β-lactamase-producing Enterobacteriaceae. Conclusions Patients with cIAI had higher mortality rates in culture-positive sepsis than in culture-negative sepsis. High SOFA score and colon involvement were the risk factors associated with culture-positivity. The most common single species grown in the blood or peritoneal cultures was Escherichia coli, and the most common group was Gram-positive cocci.

Approximately 15% of patients with diabetes mellitus (DM) are prone to developing diabetic foot ulcers (DFU) in their lifetime. The term vitamin D status or 25-hydroxyvitamin D (25(OH)D) levels is used interchangeably to represent the status of vitamin D in individuals throughout this article. Evidence suggests a relationship between 25(OH)D levels and DFU. However, very minimal data are available on the association between DFU and vitamin D deficiency. After a careful review of the literature, it was inferred that vitamin D could be associated with DFU and diabetic foot infections. Available evidence on vitamin D and DFU suggests a negative correlation between 25(OH)D levels and the presence of DFU. Evidence also supports a negative relationship between 25(OH)D levels and diabetic foot infections. Further large-scale randomized controlled studies need to be done to confirm the relationship between 25(OH)D levels and DFU including the use of vitamin D in the management of DFU and diabetic foot infections.

Current methods for tuberculosis (TB) treatment monitoring are suboptimal. We evaluated plasma matrix metalloproteinase (MMP) and procollagen III N-terminal propeptide concentrations before and during TB treatment as biomarkers. Plasma MMP-1, -8 and -10 significantly decreased during treatment. Plasma MMP-8 was increased in sputum Mycobacterium tuberculosis culture positive relative to culture negative participants, prior to (median 4609 pg/ml, IQR 2353-9048 vs 775 pg/ml, IQR 551-4920, p=0.019) and after 6 months (median 3650, IQR 1214-3888 vs 720, IQR 551-1321, p=0.008) of TB treatment. Consequently, plasma MMP-8 is a potential biomarker to enhance TB treatment monitoring and screen for possible culture positivity.

Diabetic Foot Infections

Diabetic foot infections are a common cause of morbidity and mortality in the United States, and successful treatment often requires an aggressive and prolonged approach. Recent work has elucidated the importance of appropriate therapy for a given severity of diabetic foot infection, and highlighted the ongoing risk such patients have for subsequent invasive life-threatening infection should diabetic foot ulcers fail to heal. The authors describe the case of a man with diabetes who had prolonged, delayed healing of a diabetic foot ulcer. The ulcer subsequently became infected by methicillin-resistant Staphylococcus aureus (MRSA). The infection was treated conservatively with oral therapy and minimal debridement. Several months later, he experienced MRSA bloodstream infection and complicating endocarditis. The case highlights the ongoing risk faced by patients when diabetic foot ulcers do not heal promptly, and emphasizes the need for aggressive therapy to promote rapid healing and eradication of MRSA.

Background: We sought to determine the similarity of pathogens isolated from soft tissue and bone in patients with diabetic foot infections. It is widely believed that soft-tissue cultures are adequate in the determination of causative bacteria in patients with diabetic foot osteomyelitis. The culture results of specimens taken concurrently from soft-tissue and bone infections show that the former does not predict the latter with sufficient reliability. We sought to determine the similarity of pathogens isolated from soft tissue and bone in patients with diabetic foot infections. Methods: Forty-five patients with diabetic foot infections were enrolled in the study. Patients had to have clinically suspected foot lesions of grade 3 or higher on the Wagner classification system. In patients with clinically suspected osteomyelitis, magnetic resonance imaging, scintigraphy, or histopathologic examination were performed. Bone and deep soft tissue specimens were obtained from all patients by open surgical procedures under aseptic conditions during debridement or amputation. The specimens were compared only with the other specimens taken from the same patients. Results: The results of bone and soft-tissue cultures were identical in 49% (n = 22) of cases. In 11% (n = 5) of cases there were no common pathogens. In 29% (n = 13) of cases there were more pathogens in the soft-tissue specimens; these microorganisms included microbes isolated from bone cultures. In four patients (9%) with culture-positive soft-tissue specimens, bone culture specimens remained sterile. In one patient (2%) with culture-positive bone specimen, soft-tissue specimen remained sterile. Conclusion: Culture specimens should be obtained from both the bone and the overlying deep soft tissue in patients with suspected osteomyelitis whose clinical conditions are suitable. The decision to administer antibiotic therapy should depend on these results. (J Am Podiatr Med Assoc 98(4): 290–295, 2008)
