Absence of association between persistent skin lesion and virological replication in severe disseminated monkeypox infection in solid organ transplant recipient.

The Monkeypox (mpox) virus outbreak has been controlled worldwide. We report the case of a combined pancreas-kidney transplant recipient who presented a severe and prolonged cutaneous infection with onset of 3 successive rashes while receiving tecovirimat therapy. During follow-up, skin lesions, blood and throat samples were collected. Viral culture and mpox PCR were performed. No positive viral culture was obtained from blood and throat. The lowest mpox CT-values were obtained early after onset of skin lesions and were more likely to be associated with positive viral cultures. Furthermore, we observed persistent skin lesions up to 3 months. On these persistent lesions, mpox PCR positives were obtained but were not associated with positive viral culture after 23 days. In this immunocompromised host, who was receiving tecovirimat, in accordance with existing recommendations a 21-day isolation period appeared to be adapted. That said, isolation should not be systematically extended if complete healing of skin lesions has not been achieved.

Oropharyngeal samples versus lesion specimens at diagnosis in patients infected with monkeypox virus in Northern France.

The ongoing outbreak of monkeypox virus (MPXV) is the largest one in historically non-endemic countries. Early reports described atypical epidemiological and clinical presentations. We investigated MPXV DNA detection in oropharyngeal samples (OPS), and compared the viral load to that in lesion samples at diagnosis in patients infected with MPXV. We retrospectively included patients suspected to have monkeypox in Northern France, who underwent a MPXV PCR in the Virology Laboratory, University Hospital of Lille, from May 23 to August 18, 2022. Overall, a total of 228 patients (376 samples) were included. A positive result in at least one sample was found in 138 patients (60.5%). We compared PCR results between OPS and lesion samples (i.e., cutaneous or anal/rectal samples) in patients with both samples. A positive result in OPS was observed in 54 out of 60 patients (90%). The viral load in OPS (median Ct value = 29.5; interquartile range [IQR] = 24.7-34) was significantly lower than that in lesion samples (median Ct  value = 17.8; IQR = 16.3 and 19.7) (p < 0.0001). This report shows that pharyngeal sampling does not bring additional information for the initial diagnosis in patients presenting with typical lesions.

Costal osteomyelitis due to Bartonella henselae in a 10-year-old girl.

Bartonella henselae is the bacterial agent responsible for cat scratch disease. This infection is frequently the cause of localized lymphadenitis in children. It is also sometimes responsible for endocarditis, encephalitis, hepatic peliosis and in rare cases osteomyelitis. We describe the second known case of unifocal thoracic osteomyelitis in a 10-year-old child.

COVID-19 or not COVID-19? Compared characteristics of patients hospitalized for suspected COVID-19.

During an epidemic period, we compared patients hospitalized for initial suspicion of COVID-19 but for whom an alternative diagnosis was finally retained (n = 152) with those who had COVID-19 (n = 222). Most common diagnoses were another infectious disease and heart failure. COVID-19-negative patients were more often active smokers had less often cough, fever, and digestive symptoms, as compared to the 222 COVID-19-positive patients. They had higher median neutrophil and lymphocyte counts and lower CRP level. In multivariate analysis, no current smoking, neurocognitive disorder, myalgia, and fibrinogen ≥4g/L were independently associated with a final diagnosis of COVID-19.

An underestimated sexually transmitted infection: amoebiasis.

Entamoeba histolytica is a cosmopolitan pathogenic parasite. It is spread via the feco-oral route and, to a lesser extent, via sexual intercourse. We report a case of hepatic and intestinal amoebiasis in a 67-year-old man who had never travelled to an endemic area. Abdominal CT investigations detected two liver abscesses and chronic colitis. Positive amoebic serology and a positive PCR test for E. histolytica in the hepatic liquid and faeces confirmed the diagnosis. Curative metronidazole and tiliquinol-tilbroquinol were administered successfully. The patient had been contaminated through heterosexual intercourse with his healthy French female partner who was a carrier of the parasite. Though unusual, amoebiasis as a result of sexual transmission should be considered in non-endemic areas in people who have never travelled abroad, particularly in the presence of clinical symptoms such as liver abscesses or chronic diarrhoea.

Prevalence and incidence of kidney diseases leading to hospital admission in people living with HIV in France: an observational nationwide study.

OBJECTIVES: To describe hospitalisations for kidney disease (KD) among people living with HIV (PLHIV) in France and to identify the factors associated with such hospitalisations since data on the epidemiology of KD leading to hospitalisation are globally scarce. DESIGN: Observational nationwide study using the French Programme de Médicalisation des Systèmes d'Information database. SETTING: France 2008-2013. PARTICIPANTS: Around 10 862 PLHIV out of a mean of 5 210 856 patients hospitalised each year. All hospital admissions with a main diagnosis code indicating KD (International Classification of Diseases, 10th revision codes, N00 to -N39) were collected. MAIN OUTCOME MEASURES: The prevalence and incidence of KD leading to hospital admission in PLHIV and the associated risk factors. RESULTS: The prevalence of patients hospitalised for KD was 1.5 higher in PLHIV than in the general population, and increased significantly from 3.0% in 2008 to 3.7% in 2013 (p<0.01). The main cause of hospitalisation for KD was acute renal failure (ARF, 25.4%). Glomerular diseases remained stable (6.4%) throughout the study period, focal segmental glomerulosclerosis being the main diagnosis (37.6%). Only 41.3% of patients hospitalised for glomerular disease were biopsied. The other common motives for admission were nephrolithiasis (22.1%) and pyelonephritis (22.6%).The 5-year cumulative incidence of KD requiring hospitalisation was 5.9% in HIV patients newly diagnosed for HIV in 2009. Factors associated with a higher risk of incident KD requiring hospitalisation were cardiovascular disease (HR 3.30, 95% CI 1.46 to 7.49), and, for female patients, AIDS (HR 2.45, 95% CI 1.07 to 5.58). Two-thirds of hospitalisations for incident ARF occurred in the first 2 years of follow-up. CONCLUSIONS: Hospital admission for KD is more frequent in PLHIV than in the general population and increases over time. ARF remains the leading cause. Glomerular diseases are infrequently documented by renal biopsies. Older patients and those with cardiovascular disease are particularly concerned.

Effectiveness of and obstacles to antibiotic streamlining to amoxicillin monotherapy in bacteremic pneumococcal pneumonia.

BACKGROUND: Antibiotic streamlining is pivotal to reduce the emergence of resistant bacteria. However, whether streamlining is frequently performed and safe in difficult situations, such as bacteremic pneumococcal pneumonia (BPP), has still to be assessed. METHODS: All adult patients admitted to Dijon Hospital (France) from 2005 to 2013 who had BPP without complications, and were alive on the third day were enrolled. Clinical, biological, radiological, microbiological and therapeutic data were recorded. A first analysis was conducted to assess factors associated with being on amoxicillin on the third day. A second analysis, adjusting for a propensity score, was performed to determine whether 30-day mortality was associated with streamlining to amoxicillin monotherapy. RESULTS: Of the 196 patients hospitalized for BPP, 161 were still alive on the third day and were included in the study. Treatment was streamlined to amoxicillin in 60 patients (37%). Factors associated with not streamlining were severe pneumonia (OR 3.11, 95%CI [1.23-7.87]) and a first-line antibiotic combination (OR 3.08, 95%CI [1.34-7.09]). By contrast, starting with amoxicillin monotherapy correlated inversely with the risk of subsequent treatment with antibiotics other than amoxicillin (OR 0.06, 95%CI [0.01-0.30]). The Cox model adjusted for the propensity-score analysis showed that streamlining to amoxicillin during BPP was not significantly associated with a higher risk of 30-day mortality (HR 0.38, 95%CI [0.08-1.87]). CONCLUSIONS: Streamlining to amoxicillin is insufficiently implemented during BPP. This strategy is safe and potentially associated with ecological and economic benefits; therefore, it should be further encouraged, particularly when antibiotic combinations are started for severe pneumonia.

Streptococcus pyogenes: an unusual cause of salpingitis. Case report and review of the literature.

BACKGROUND: Streptococcus pyogenes can colonize genitourinary tract, but it is a rare cause of salpingitis. CASE REPORT: We report a case of bilateral salpingitis due to Streptococcus pyogenes in a 34-year-old woman using an intra-uterine device and which occurred following a family history of recurrent S. pyogenes infections. We review 12 other cases reported in the literature, and discuss the pathophysiological mechanisms of this potentially life-threatening disease. CONCLUSION: It is important to take into account consider Streptococcus pyogenes as a cause of acute salpingitis in the context of recent intra-familial Streptococcus pyogenes infections.

Necrosis of the intranasal structures and soft palate as a result of heroin snorting: a case series.

BACKGROUND: The link between nasal inhalation of cocaine and nasal and palatal necrosis is well documented. In contrast, few data are available concerning nasal mucosa necrosis related to heroin snorting. The authors report here the retrospective analysis of 24 cases of orofacial lesions in patients with nasal heroin usage, collected between 2006 and 2012. CASES: The cases concern 17 males and 7 females (median age 29.5 (range: 24-42)) with chronic consumption of intranasal heroin (from 2 months to more than 10 years). Six patients had a history of cocaine abuse. The median daily amount of heroin consumption was 5 g (range: 0.5-10). The complications were nasal perforation (11 cases), nasal ulceration or erythema (5 cases), nasal septum necrosis (5 cases), pharyngeal ulceration (3 cases), and palate damages (5 cases). The most common clinical signs and symptoms were nasal pain, purulent sputum, dysphagia, and rhinitis. Maintenance therapy with methadone (19 cases) or buprenorphine (3 cases) was initiated. In 8 cases, the injury improved. DISCUSSION: The potential of heroin to induce destructive orofacial lesions should be considered when nasal damages are observed in patients with drug abuse. A multidisciplinary approach seems to be the most effective means of managing such patients.
