RESUMO
In march 2020, the International Working Group on the Diabetic Foot (IWGDF) published an update of the 2015 guidelines on the diagnosis and management of diabetic foot infection (DFI). While we (the French ID society, SPILF) endorsed some of these recommendations, we wanted to update our own 2006 guidelines and specifically provide informative elements on modalities of microbiological diagnosis and antibiotic treatment (especially first- and second-line regiments, oral switch and duration). The recommendations put forward in the present guidelines are addressed to healthcare professionals managing patients with DFI and more specifically focused on infectious disease management of this type of infection, which clearly needs a multidisciplinary approach. Staging of the severity of the infection is mandatory using the classification drawn up by the IWGDF. Microbiological samples should be taken only in the event of clinical signs suggesting infection in accordance with a strict preliminarily established protocol. Empirical antibiotic therapy should be chosen according to the IWGDF grade of infection and duration of the wound, but must always cover methicillin-sensitive Staphylococcus aureus. Early reevaluation of the patient is a fundamental step, and duration of antibiotic therapy can be shortened in many situations. When osteomyelitis is suspected, standard foot radiograph is the first-line imagery examination and a bone biopsy should be performed for microbiological documentation. Histological analysis of the bone sample is no longer recommended. High dosages of antibiotics are recommended in cases of confirmed osteomyelitis.

OBJECTIVES: Reducing antibiotic consumption has now become a major public health priority. Reducing treatment duration is one of the means to achieve this objective. Guidelines on the therapeutic management of the most frequent infections recommend ranges of treatment duration in the ratio of one to two. The Recommendation Group of the French Infectious Diseases Society (SPILF) was asked to collect literature data to then recommend the shortest treatment durations possible for various infections. METHODS: Analysis of the literature focused on guidelines published in French and English, supported by a systematic search on PubMed. Articles dating from one year before the guidelines publication to August 31, 2015 were searched on the website. RESULTS: The shortest treatment durations based on the relevant clinical data were suggested for upper and lower respiratory tract infections, central venous catheter-related and uncomplicated primary bacteremia, infective endocarditis, bacterial meningitis, intra-abdominal, urinary tract, upper reproductive tract, bone and joint, skin and soft tissue infections, and febrile neutropenia. Details of analyzed articles were shown in tables. CONCLUSION: This work stresses the need for new well-conducted studies evaluating treatment durations for some common infections. Following the above-mentioned work focusing on existing literature data, the Recommendation Group of the SPILF suggests specific study proposals.

INTRODUCTION: The aim of this study was to evaluate the vaccinal status among Croix-Rousse Hospital workers, attitude towards this vaccination, and the information delivered in order to promote this vaccination. METHODS: Questionnaires were delivered by electronic mailing. RESULTS: Six hundred (and) twenty-nine questionnaires were analyzed (26.7% of hospital workers); 30.7% of responders were vaccinated against influenza, 89.2% of responders were aware of influenza and vaccine. Vaccine coverage was lower in younger workers, non health-care workers, non physician health-care workers, and surgeons who responded. Motivation and reserve varied according to the status, position, and age, with some discrepancies. CONCLUSION: These results suggest implementing a better targeted vaccination campaign, according to the various categories of personnel.

Acute respiratory bacterial infection is the most common complication of influenza and a leading cause for excess rate of outpatient visits, hospitalization, and death (pneumonia). Influenza promotes bacterial infection as stated by epidemiologic evidence of temporal association between outbreaks or peaks of both influenza and bacterial pneumonia. The bacteria involved are Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus. However, Gram-negative rods, Klebsiella pneumoniae, Pseudomonas aeruginosa, anaerobes and methicillin resistant S. aureus may be involved in institutionalized elderly patients. Various studies confirm that antibiotics are over-prescribed in patients with influenza or influenza like illness, even in the absence of bacterial infection signs, and in patients without comorbidity. No data has proven the benefice of antibiotic prescription in influenza-infected patients without bacterial infection. Neuraminidase inhibitors may be of interest for the management of influenza infected patients, because they can decrease the risk of bacterial complications and the use of antibiotics.

Seventeen diabetic patients with moderate to mild foot lesions associated with 20 osteomyelitic bones diagnosed by both bone scan and bone biopsy received rifampicin plus ofloxacin for a median duration of 6 months. Cure was defined as disappearance of all signs and symptoms of infection at the end of the treatment and absence of relapse during follow up. At the end of the treatment period, cure was achieved in 15 patients (88.2%) and was maintained in 13 patients (76.5%) at the end of an average post-treatment follow-up of 22 months. No serious drug-related adverse events were recorded.

BACKGROUND: Fatal lactic acidosis is a serious complication of therapy with nucleoside analogues. OBJECTIVE: To examine symptomatic hyperlactataemia in HIV-infected adults treated with antiretroviral drugs. METHODS: In this prospective study, arterial blood lactate levels were measured in patients presenting with unexplained clinical symptoms. When these levels were high, functional respiratory tests (FRT) were carried out. Liver or muscle biopsies were further proposed. Incidences were calculated by comparison with the entire cohort of patients treated in the department. RESULTS: Fourteen HIV-infected adults treated with antiretroviral drugs were identified with symptomatic hyperlactataemia during a 2-year period follow-up study. The incidence of hyperlactataemia was 0.8% per year but reached 1.2% if only patients treated with a regimen including stavudine were considered. Clinical symptoms included abnormal fatigue, tachycardia, abdominal pain, weight loss, peripheral neuropathy, and more specifically exercise-induced dyspnoea occurring despite effective antiretroviral treatment. FRT showed a metabolic deviation towards anaerobiosis with a high lactate/pyruvate ratio. Ultrastructural mitochondrial abnormalities were seen in all four patients for whom this was examined. There was a marked decrease in complex IV activity in muscle biopsies from four of five patients, consistent with a mitochondrial dysfunction. Evolution was favourable in 13 patients, probably because of an early diagnosis. CONCLUSIONS: Potentially fatal adverse events occurring during antiretroviral treatment may be avoided by close monitoring of clinical signs and blood lactate levels. If other studies confirm that the cumulative long-term toxicity of antiretroviral drugs results from mitochondrial dysfunction, the incidence of hyperlactataemia and its clinical consequences may become more important.

INTRODUCTION: Management of HIV infection considerably improved over the past few years. Factors that contributed to this improvement are the following: better knowledge of the dynamics of viral replication and immune response, plasma viral load quantitation, use of new combinations with more potent antiretroviral drugs, simultaneous progress in treatment of opportunistic infections. As a result, potential for drug interactions increased. CURRENT KNOWLEDGE AND KEY POINTS: Due to changes in hepatic metabolism, protease inhibitors may interact with concurrent treatment. The most relevant known drug interactions with each of the protease inhibitor (saquinavir, indinavir, ritonavir and nelfinavir) are summarized. Due to toxicity risks, co-administration is contraindicated for various interacting drugs, whereas dosage adjustments may only be required for others. Such interactions have relevant consequences in clinical practice for the choice of the combination that should be prescribed. However, they may have direct therapeutical benefit to the patient, particularly in the case of protease inhibitors. FUTURE PROSPECTS AND PROJECTS: Though potential drug interactions require careful monitoring in clinical practice, they should not limit the use and therefore therapeutical benefit conferred by these highly active drugs. To better define the value of combinations of protease inhibitors and treatment with non-nucleosidic reverse transcriptase inhibitor, further studies are required. As the number of drugs increases, experience and clinical practice in treatment of HIV infection will allow better knowledge of drug interactions and thereby optimal management of HIV-infected individuals.

A protective effect of interleukin-10 (IL-10) against the development of lethal shock has been demonstrated in various animal models. In contrast, the immunosuppressant properties of this mediator have been minimally evaluated in low-mortality models of infections. The clinical, microbiological, and inflammatory effects of murine recombinant IL-10 (mrIL-10) therapy were evaluated in two models of peritonitis in rats, which differed in the degree of severity of peritoneal inflammation 3 days after inoculation of Escherichia coli and Bacteroides fragilis with or without Enterococcus faecalis. The severity of the disease remained unchanged compared to that in control animals. A dose-related decrease in the peritoneal phagocyte count was observed in the treated groups compared to the counts in control animals. The subsequent experiments were performed exclusively in the mixed gram-positive-gram negative model, which exhibits an intense and prolonged inflammatory response with similar criteria. The early effects of mrIL-10 (evaluated 6 h after inoculation), repeated injections of mrIL-10 (four doses injected from 0 to 9 h after bacterial challenge), and pretreatment (two doses injected 6 and 3 h before inoculation) were evaluated. The clinical and microbiological parameters remained unchanged in the treated animals. Decreases in the peritoneal phagocyte count and the peritoneal concentration of tumor necrosis factor were observed following repeated injections of mrIL-10. In summary, our data suggest that mrIL-10 does not worsen the manifestations of sepsis. However, these results need to be confirmed in clinical practice.

Our objectives were to evaluate tolerance and compliance of post-exposure triple therapy in health-care workers (HCWs) by retrospective observational study. Structured telephone interview of HCWs identified through data from antiretroviral prescribing centres. Twenty HCWs who received triple prophylaxis were identified over one year. Sixteen agreed to participate in the study. All but one source patient had documented HIV infection. Half HCWs were not aware of post-exposure therapy. Most HCWs received a zidovudine, lamivudine and indinavir combination. All completed at least 4 weeks of therapy. Only 50% received their first dosage less than 4 h after exposure. Nearly all experienced adverse events, mostly digestive (nausea and abdominal pain n=15) or psychological (anxiety and depression n=15), none resulting in therapy discontinuation. Most events occurred 2 to 7 days after therapy initiation. Most modified their sexual life with abstinence or condom use. Compliance was excellent. Half HCWs did not miss any tablet, 4 forgot one dosing a month and 4 one dosing a week. Follow up is over 6 months in all but one HCW. No HIV seroconversion has been observed to date. In France, post-exposure triple antiretroviral therapy is widely available 24 h a day in every emergency room but further training and development of HCWs is needed to decrease consulting time and increase referral to specialized physicians. Notable moderate adverse events, both physical and psychological are noted, however, compliance is excellent.

In apparently localized amyloidosis, there is no appropriate test to determine whether systemic deposits exist. We studied the value of serum amyloid P component (SAP) scintigraphy and labial salivary gland (LSG) biopsy on patients with apparently localized amyloidosis in 12 patients who had neither clinical nor biological evidence of systemic amyloidosis. All patients had an LSG biopsy and echocardiography. Iodine-123-labelled serum amyloid P component (123I-SAP) scintigraphy was performed in all patients. Whole-body scintigraphy was done, and tissue retention was evaluated at 24 h and 48 h. Of these 12 patients, three had amyloidosis in their LSG and had abnormal 123I-SAP scintigraphy; these three had a secondary clinical history of systemic amyloidosis. Three other patients had abnormal 123I-SAP scintigraphy without detectable systemic amyloid deposits, but one had a previous history of bilateral carpal tunnel syndrome treated with infiltration. 123I-SAP scintigraphy in association with LSG biopsy may be helpful in determining the localized or systemic character of amyloid disease.

OBJECTIVE: The purpose of this study was to assess the value of the serum amyloid P (SAP) component scintigraphy in patients with primary amyloidosis (AL). MATERIAL AND METHODS: Pure human SAP labeled with iodine-123 (123I-SAP) was given intravenously to 24 patients with biopsy-proven systemic amyloidosis (15 without multiple myeloma = group 1, and 9 with multiple myeloma = group 2) and to 6 patients with multiple myeloma without any clinical or biological signs of amyloidosis (group 3). Whole-body images as well as regional views and tissue retention levels were obtained after 24 hours. Our study was approved by the institutional review committee and all individuals gave informed consent and were prospectively studied (median 13 months, range 1 to 47 from the date of the scintigraphy to May 1995). RESULTS: Organ localization of 123I-SAP, indicating the presence of substantial visceral amyloid deposits, was observed in all patients in group 1 and 2. The organ uptake of 123I-SAP included the spleen (1 patient was splenectomized) in 20 of 23 cases (87%), the liver in 15 of 24 (60%), and the kidneys in 6 of 24 (25%). Myocardial 123I-SAP was never seen although 13 out of the 24 patients had clinical or echographic data for amyloidosis. Twenty-four hour tissue retention was significantly elevated in all patients (group 1 and group 2): 55.66% +/- 19.16% in group 1 and 34.37% +/- 24.92% in group 2, as compared with normal levels < 24%. The sensitivity of the technique was 79% when only organ uptake was considered but reached 100% when tissue retention was also considered. The 24-hour tissue retention might be correlated with the severity of the amyloidosis: mean survival in patients with tissue retention greater than 50% was 11.3 months versus 24.5 months in patients with levels less or equal to 50%. Five of the 6 patients with multiple myeloma without evidence of amyloidosis had abnormal 123I-SAP imaging and 24-hour tissue retention levels. In 2 of them, amyloidosis was secondly detected. In the 9 patients who had two scintigraphies, variations in 24-hour tissue retention values were in accordance with the clinical evaluation. CONCLUSIONS: Spleen and liver distribution of amyloidosis is mostly revealed by 123I-SAP scintigraphy in patients with AL amyloidosis. The uptake of 123I-SAP appeared in proportion to the quantity of amyloidosis present in different tissues, and the relative quantity of amyloid deposits in the myocardium, carpal tunnel, digestive tract, and kidneys was often small and seldom visualized by 123I-SAP scintigraphy. In contrast 24-hour tissue retention levels were abnormal in all cases of known AL amyloidosis. This may be a positive argument for the diagnosis of amyloidosis when histopathological tests are normal. Tissue retention levels appear important as they may be correlated with survival.

Purified human SAP labeled with iodine-123(123I-SAP) was given intravenously to 24 patients with biopsy-proved systemic primary amyloidis. Spleen and liver distribution of amyloidis is mostly revealed by 123I-SAP scintigraphy and the importance of retention may be correlated with the survival.
