Management of erythropoietic protoporphyria with cholestatic liver disease: A case report.

Erythropoietic protoporphyria (EPP) is a rare metabolic disease of the heme biosynthetic pathway where an enzymatic dysfunction results in protoporphyrin IX (PPIX) accumulation in erythroid cells. The porphyrins are photo-reactive and are responsible for severe photosensitivity in patients, thus drastically decreasing their quality of life. The liver eliminates PPIX and as such, the main and rare complication of EPP is progressive cholestatic liver disease, which can lead to liver failure. The management of this complication is challenging, as it often requires a combination of approaches to promote PPIX elimination and suppress the patient's erythropoiesis. Here we described a 3-year follow-up of an EPP patient, with three episodes of liver involvement, aggravated by the coexistence of a factor VII deficiency. It covers all the different types of intervention available for the management of liver disease, right through to successful allogeneic hematopoietic stem cell transplantation.

Aseptic Abscess Syndrome: Clinical Characteristics, Associated Diseases, and up to 30 Years' Evolution Data on a 71-Patient Series.

Aseptic abscess (AA) syndrome is a rare type of inflammatory disorder involving polymorphonuclear neutrophils (PMNs), often associated with inflammatory bowel disease (IBD). This study sought to describe the clinical characteristics and evolution of this syndrome in a large cohort. We included all patients included in the French AA syndrome register from 1999 to 2020. All patients fulfilled the criteria outlined by André et al. in 2007. Seventy-one patients were included, 37 of which were men (52.1%), of a mean age of 34.5 ± 17 years. The abscesses were located in the spleen (71.8%), lymph nodes (50.7%), skin (29.5%), liver (28.1%), lung (22.5), and rarer locations (brain, genitals, kidneys, ENT, muscles, or breasts). Of all the patients, 59% presented with an associated disease, primarily IBD (42%). They were treated with colchicine (28.1%), corticosteroids (85.9%), immunosuppressants (61.9%), and biologics (32.3%). A relapse was observed in 62% of cases, mostly in the same organ. Upon multivariate analysis, factors associated with the risk of relapse were: prescription of colchicine (HR 0.52; 95% CI [0.28-0.97]; p = 0.042), associated IBD (HR 0.57; 95% CI [0.32-0.99]; p = 0.047), and hepatic or skin abscesses at diagnosis (HR 2.14; 95% CI [1.35-3.40]; p = 0.001 and HR 1.78; 95% CI [1.07-2.93]; p = 0.024, respectively). No deaths occurred related to this disease. This large retrospective cohort study with long follow up showed that AA syndrome is a relapsing systemic disease that can evolve on its own or be the precursor of an underlying disease, such as IBD. Of all the available treatments, colchicine appeared to be protective against relapse.

Trends in the risk of myocardial infarction among HIV-1-infected individuals relative to the general population in France: Impact of gender and immune status.

We examined trends in the MI incidence and age at MI diagnosis among adults living with HIV-1 between 2000 and 2009, by comparison with the French MI registries, by gender. Age standardized incidence rates and standardized incidence-ratios (SIRs) were estimated for individuals included in the French hospital database on HIV (n = 71 204, MI = 663) during three periods: 2000-2002, 2003-2005 and 2006-2009. Median ages at MI diagnosis were compared using the Brown-Mood test. Over the study periods, the absolute rate difference and relative risks were higher in women than in men in 2000-2002 and 2006-2009, with respective SIRs 1.99 (1.39-2.75) and 1.12 (0.99-1.27) in 2006-2009. The trends were different for men and women with a decreasing trend in SIRs in men and no change in women. In both sexes, among individuals with CD4 ≥500/µL and controlled viral-load on cART, the risk was no longer elevated. Age at MI diagnosis was significantly younger than in the general population, especially among women (-6.2 years, p<0.001; men: -2.1 years, p = 0.02). In HIV-1-positive adults, absolute rate difference and relative risks and trends of MI were different between men and women and there was no additional risk among individuals on effective cART.

Lack of effects of statins on high-density lipoprotein subfractions in HIV-1-infected patients receiving protease inhibitors.

BACKGROUND: We evaluated the effect of 45 days of rosuvastatin or pravastatin treatment on the distribution of HDL subfractions in HIV-1-infected individuals receiving boosted protease inhibitors (PIs) with cardiovascular risk. METHODS: The distribution of HDL subclasses by gradient gel electrophoresis was blindly assessed in 74 HIV-1-infected individuals receiving boosted PIs at baseline and at day 45 of statin treatment, and compared with the distribution obtained in 63 healthy normolipidemic individuals taken as controls. RESULTS: No significant modification appeared in HDL distribution between the two arms of statins for the HIV-1-infected individuals. Nevertheless, when compared to controls, HDL subfractions showed a significantly lower HDL2b proportion and significantly higher proportions of HDL2a and HDL3b (P<0.001). CONCLUSION: No difference was observed in HDL distribution between pravastatin and rosuvastatin after 45 days treatment, in HIV-1-infected individuals under PIs. Nevertheless, when compared to healthy normolipidemic subjects, HDL distribution is clearly different, with a distribution in HIV-infected individuals under PIs associated with an increased cardiovascular risk.

Mutation in the L3 Ribosomal Protein Could Be Associated with Risk of Selection of High-Level Linezolid-Resistant Staphylococcus epidermidis Strains.

Linezolid (LZD) has arisen as an alternative treatment in diabetic foot osteitis due to staphylococci. LZD resistance selection is difficult and involved various molecular mechanisms. As a better knowledge of those mechanisms could be beneficial for pathogenic strains' screening, we simulated in vitro the spontaneous mutagenesis process that leads to LZD-resistant strains from two Staphylococcus epidermidis strains responsible for monomicrobial diabetic foot osteitis. LZD high resistance was selected for both strains, with the same timeline of mutation appearance. Mutation in L3 protein (G152D) occurred first and quickly, but did not cause phenotypically detectable resistance or fitness cost. It was later followed by different 23S rRNA mutations (G2505A, G2447T), leading this time to detectable resistance (minimum inhibitory concentration [MIC] ≥8 mg/L). This phenomenon underlies the difficulty of resistance selection in coagulase-negative staphylococci (CoNS). This study is the first description of G2505A mutation in CoNS. Various phenotypical impacts were observed depending on strain and mutation: (i) fitness cost of G2505A and G2447T mutations; (ii) loss of erythromycin resistance concomitantly with L3 mutation selection; (iii) correlation between number of mutated rrl copies and LZD resistance level for G2447T. In conclusion, the risk of selection of high-level LZD-resistant S. epidermidis strains is weak, but does exist. It could probably appear in case of long-term treatment and be favored in the case of a pre-existing mutation in L3 ribosomal protein. Thus, broad screening conditions for pathogenic strains should probably be considered.

Is Impact of Statin Therapy on All-Cause Mortality Different in HIV-Infected Individuals Compared to General Population? Results from the FHDH-ANRS CO4 Cohort.

BACKGROUND: The effect of statins on all-cause mortality in the general population has been estimated as 0.86 (95%CI 0.79-0.94) for primary prevention. Reported values in HIV-infected individuals have been discordant. We assessed the impact of statin-based primary prevention on all-cause mortality among HIV-infected individuals. METHODS: Patients were selected among controls from a multicentre nested case-control study on the risk of myocardial infarction. Patients with prior cardiovascular or cerebrovascular disorders were not eligible. Potential confounders, including variables that were associated either with statin use and/or death occurrence and statin use were evaluated within the last 3 months prior to inclusion in the case-control study. Using an intention to continue approach, multiple imputation of missing data, Cox's proportional hazard models or propensity based weighting, the impact of statins on the 7-year all-cause mortality was evaluated. RESULTS: Among 1,776 HIV-infected individuals, 138 (8%) were statins users. During a median follow-up of 53 months, 76 deaths occurred, including 6 in statin users. Statin users had more cardiovascular risk factors and a lower CD4 T cell nadir than statin non-users. In univariable analysis, the death rate was higher in statins users (11% vs 7%, HR 1.22, 95%CI 0.53-2.82). The confounders accounted for were age, HIV transmission group, current CD4 T cell count, haemoglobin level, body mass index, smoking status, anti-HCV antibodies positivity, HBs antigen positivity, diabetes and hypertension. In the Cox multivariable model the estimated hazard ratio of statin on all-cause mortality was estimated as 0.86 (95%CI 0.34-2.19) and it was 0.83 (95%CI 0.51-1.35) using inverse probability treatment weights. CONCLUSION: The impact of statin for primary prevention appears similar in HIV-infected individuals and in the general population.

Kikuchi-Fujimoto disease: retrospective study of 91 cases and review of the literature.

Kikuchi-Fujimoto disease (KFD) is a rare cause of lymphadenopathy, most often cervical. It has been mainly described in Asia. There are few data available on this disease in Europe. We conducted this retrospective, observational, multicenter study to describe KFD in France and to determine the characteristics of severe forms of the disease and forms associated with systemic lupus erythematosus (SLE). We included 91 cases of KFD, diagnosed between January 1989 and January 2011 in 13 French hospital centers (median age, 30 ±â€Š10.4 yr; 77% female). The ethnic origins of the patients were European (33%), Afro-Caribbean (32%), North African (15.4%), and Asian (13%). Eighteen patients had a history of systemic disease, including 11 with SLE. Lymph node involvement was cervical (90%), often in the context of polyadenopathy (52%), and it was associated with hepatomegaly and splenomegaly in 14.8% of cases. Deeper sites of involvement were noted in 18% of cases. Constitutional signs consisted mainly of fever (67%), asthenia (74.4%), and weight loss (51.2%). Other manifestations included skin rash (32.9%), arthromyalgia (34.1%), 2 cases of aseptic meningitis, and 3 cases of hemophagocytic lymphohistiocytosis. Biological signs included lymphocytopenia (63.8%) and increase of acute phase reactants (56.4%). Antinuclear antibodies (ANAs) and anti-DNA antibodies were present in 45.2% and 18% of the patients sampled, respectively. Concomitant viral infection was detected in 8 patients (8.8%). Systemic corticosteroids were prescribed in 32% of cases, hydroxychloroquine in 17.6%, and intravenous immunoglobulin in 3 patients. The disease course was always favorable. Recurrence was observed in 21% of cases. In the 33 patients with ANA at diagnosis, SLE was known in 11 patients, diagnosed concomitantly in 10 cases and in the year following diagnosis in 2 cases; 6 patients did not have SLE, and 4 patients were lost to follow-up (median follow-up, 19 mo; range, 3-39 mo). The presence of weight loss, arthralgia, skin lesions, and ANA was associated with the development of SLE (p < 0.05). Male sex and lymphopenia were associated with severe forms of KFD (p < 0.05). KFD can occur in all populations, irrespective of ethnic origin. Deep forms are common. An association with SLE should be investigated. A prospective study is required to determine the risk factors for the development of SLE.

Diagnosing diabetic foot osteomyelitis in patients without signs of soft tissue infection by coupling hybrid 67Ga SPECT/CT with bedside percutaneous bone puncture.

OBJECTIVE: Successful treatment of osteomyelitis is more likely with accurate diagnosis and identification of the causative pathogens. This typically requires obtaining a specimen of bone, usually by image-guided biopsy. We sought to develop a simpler bedside method for definitively diagnosing osteomyelitis. RESEARCH DESIGN AND METHODS: Over 2 years, we enrolled consecutive patients presenting to our diabetic foot clinic with a foot ulcer and clinically suspected osteomyelitis but without soft tissue infection. Each underwent hybrid (67)Ga single-photon emission computed tomography and X-ray computed tomography (SPECT/CT) imaging; those with a positive scan underwent bedside percutaneous bone puncture. Patients with a positive bone culture received culture-guided antibiotic therapy. Patients with negative (67)Ga SPECT/CT imaging or with positive imaging but negative bone culture were not treated with antibiotics. All patients were followed up for ≥ 1 year. RESULTS: Among 55 patients who underwent (67)Ga SPECT/CT imaging, 13 had negative results and all of their foot ulcers resolved without antibiotic therapy. Among 42 with positive imaging, 2 were excluded (for recent antibiotic therapy) and 40 had bone punctures (3 punctured twice): 19 had negative results, 3 of which were likely false negatives, and 24 had positive results (all gram-positive cocci). At follow-up, 3 patients had died, 3 had undergone amputation, and 47 had no evidence of foot infection. The sensitivity and specificity of this combined method were 88.0 and 93.6%, respectively, and the positive and negative predictive values were 91.7 and 90.7%, respectively. CONCLUSIONS: Coupling of (67)Ga SPECT/CT imaging and bedside percutaneous bone puncture appears to be accurate and safe for diagnosing diabetic foot osteomyelitis in patients without signs of soft tissue infection, obviating the need for antibiotic treatment in 55% of suspected cases.

[Can narrative medicine be an answer to patient physician relationship teaching according to students' demand in medical education curricula?]. / L'enseignement de la médecine narrative peut-il être une réponse à l'attente de formation des étudiants à la relation médecin-malade ?

INTRODUCTION: Coming from literature and medicine and medical humanities north American seminars, narrative medicine has applied narratology for analyzing patients' discourse and has been taught during a decade. METHODS: At Paris Descartes School of Medicine a twenty-hour narrative medicine elective program including whole class lectures and writing and reading small group exercises for second year medical students has been assessed using satisfaction questionnaires. RESULTS: Although several students were uncomfortable with the first writing and reading exercises, the whole satisfaction scores demonstrate that this new program is very well appreciated even when students did not choose this program because they were interested with the patient physician relationship. These results have been confirmed when all students state this program should be continued and when half of them state this program should be offered to more students or made mandatory. DISCUSSION: The primary focus on literary characteristics of patients' and physicians' discourses, without ignoring psychoanalysis theory, has shown to be safe for young students. Writing exercises are encouraged but not mandatory, and reading is optional if ever they feel embarrassed after producing their own texts. Narrative medicine impact on students' attitudes and behaviors has now to be assessed before implementing new educational programs.

Twelve months of routine HIV screening in 6 emergency departments in the Paris area: results from the ANRS URDEP study.

OBJECTIVE: In October 2009 the French National Authority for Health recommended that HIV testing be proposed at least once to all persons aged 15 to 70 years in all healthcare settings. We examined whether routine HIV screening with a rapid test in emergency departments (EDs) was feasible without dedicated staff, and whether newly diagnosed persons could be linked to care. METHODS: This one-year study started in December 2009 in 6 EDs in the Paris area, using the INSTI™ test. Eligible individuals were persons 18 to 70 years old who did not present for a vital emergency, for blood or sexual HIV exposure, or for HIV screening. Written informed consent was required. RESULTS: Among 183 957 eligible persons, 11 401 were offered HIV testing (6.2%), of whom 7936 accepted (69.6%) and 7215 (90.9%) were tested (overall screening rate 3.9%); 1857 non eligible persons were also tested. Fifty-five new diagnoses of HIV infection were confirmed by Western blot (0.61% (95% CI 0.46-0.79). There was one false-positive rapid test result. Among the newly diagnosed persons, 48 (87%) were linked to care, of whom 36 were not lost to follow-up at month 6 (75%); median CD4 cell count was 241/mm(3) (IQR: 52-423/mm(3)). CONCLUSIONS: Screening rates were similar to those reported in opt-in studies with no dedicated staff. The rate of new diagnoses was similar to that observed in free anonymous test centres in the Paris area, and well above the prevalence (0.1%) at which testing has been shown to be cost-effective.

Effects of rosuvastatin versus pravastatin on low-density lipoprotein diameter in HIV-1-infected patients receiving ritonavir-boosted protease inhibitor.

OBJECTIVE: HIV infection is associated with an atherogenic lipoprotein profile, and ritonavir-boosted protease inhibitors exacerbate this phenotype. We evaluated the effect of 45 days of rosuvastatin versus pravastatin on the low-density lipoprotein (LDL) size and the distribution of LDL subfractions in HIV-1 patients receiving boosted protease inhibitors with elevated LDL levels. DESIGN: Substudy of the randomized double-blind multicentre ANRS 126 VIHstatine trial. SETTING: Twenty clinical centres in France. PATIENTS: HIV-infected patients receiving boosted protease inhibitors with dyslipidaemia (LDL cholesterol > 4.1 mmol/l and triglycerides < 8.8 mmol/l). INTERVENTION: Rosuvastatin 10 mg/day (n = 39) or pravastatin 40 mg/day (n = 37) for 45 days. MAIN OUTCOME MEASURE(S): LDL size and distribution of LDL subfractions blindly assessed by gradient gel electrophoresis at baseline and at day 45. RESULTS: Rosuvastatin was more effective than pravastatin in increasing the diameter of the LDL peak. The LDL diameter change was 0.33 ± 0.59 nm in the rosuvastatin group versus -0.01 ± 0.52 nm in the pravastatin group (P = 0.021). Rosuvastatin was also more effective in increasing significantly the percentage of large LDL (LDL1, P = 0.038; LDL2, P = 0.031) and in decreasing the percentage of small LDL (LDL3, P = 0.009). CONCLUSION: Rosuvastatin was more effective than pravastatin in normalizing LDL size and LDL subfraction distributions, leading to a less atherogenic phenotype.

[Eye and corticosteroid's use]. / Indications et complications des corticoïdes en ophtalmologie.

Most common side effects of systemic corticosteroids are posterior subcapsular cataract and glaucoma. There is no way to prevent corticosteroid-induced cataract. The risk of these complications varies (cataract 11 to 15%; glaucoma 12.8%), and it depends on the dose, duration of administration and terrain. The discontinuation of corticosteroid therapy is required in cases of uncontrolled glaucoma by hypotonic treatment. Long-term topical or general steroids prescription has to be done after an ophthalmological examination. Indications of ophthalmic general corticosteroids are acute orbital and ocular inflammations. affecting the middle and posterior segments of the eye, or sclera when topical treatment is ineffective. When administered topically, only 5% of the delivered dose is absorbed by the anterior segment, distribution is almost zero in the middle and posterior segments of the eye.

Urogenital manifestations in Wegener granulomatosis: a study of 11 cases and review of the literature.

We describe the main characteristics and treatment of urogenital manifestations in patients with Wegener granulomatosis (WG). We conducted a retrospective review of the charts of 11 patients with WG. All patients were men, and their median age at WG diagnosis was 53 years (range, 21-70 yr). Urogenital involvement was present at onset of WG in 9 cases (81%), it was the first clinical evidence of WG in 2 cases (18%), and was a symptom of WG relapse in 6 cases (54%). Symptomatic urogenital involvement included prostatitis (n = 4) (with suspicion of an abscess in 1 case), orchitis (n = 4), epididymitis (n = 1), a renal pseudotumor (n = 2), ureteral stenosis (n = 1), and penile ulceration (n = 1). Urogenital symptoms rapidly resolved after therapy with glucocorticoids and immunosuppressive agents. Several patients underwent a surgical procedure, either at the time of diagnosis (n = 3) (consisting of an open nephrectomy and radical prostatectomy for suspicion of carcinoma, suprapubic cystostomy for acute urinary retention), or during follow-up (n = 3) (consisting of ureteral double J stents for ureteral stenosis, and prostate transurethral resection because of dysuria). After a mean follow-up of 56 months, urogenital relapse occurred in 4 patients (36%). Urogenital involvement can be the first clinical evidence of WG. Some presentations, such as a renal or prostate mass that mimics cancer or an abscess, should be assessed to avoid unnecessary radical surgery. Urogenital symptoms can be promptly resolved with glucocorticoids and immunosuppressive agents. However, surgical procedures, such as prostatic transurethral resection, may be mandatory in patients with persistent symptoms.

[Role of corticosteroids in infectious disease]. / Place des corticoïdes dans le traitement des infections.

Corticosteroids, when used in prolonged treatments, increase the chances of bacterial and fungal infections. The advantage of corticotherapy combined with specific anti-infective treatment has been proven for certain bacterial and fungal infections. There is no evidence favouring the prescription of anti-inflammatory corticosteroids for infections in the ENT area. Corticosteroids, even in short-term treatments, must always be prescribed in combination with antibiotics in the course of infections. Corticosteroids make it possible to limit the deleterious effects caused by the activation of the immune system at the time of certain infections, and lesions linked to acute inflammation. The duration of the prescription of corticosteroids must be reduced to a minimum during sepsis.

Determinants of low-density lipoprotein particle diameter during antiretroviral therapy including protease inhibitors in HIV-1-infected patients.

BACKGROUND: Lipid disorders are frequent in HIV-1-infected patients taking combination antiretroviral therapy (cART) that includes protease inhibitors (PIs). The presence of small dense low-density lipoprotein particles might be an important predictive marker of cardiovascular disease in this setting. This cross-sectional substudy of the ANRS 126 trial was designed to identify variables influencing LDL diameter. METHODS: We studied 81 stable HIV-1-infected patients with dyslipidaemia (LDL-cholesterol >4.1 mmol/l, triglycerides <8.8 mmol/l) receiving PI-including cART regimens and no lipid-lowering drugs. LDL diameter was assessed by gradient gel electrophoresis. Relationships between LDL diameter and demographic, metabolic and HIV-related variables were identified by using non-parametric univariate tests and multiple linear regression models. RESULTS: In univariate analysis, LDL diameter was related to demographic variables, triglyceride (TG) levels, high-density lipoprotein cholesterol (HDL-c) levels, and the numbers and duration of exposure to nucleoside reverse transcriptase inhibitors and PIs. In multivariable linear regression analysis, LDL diameter was negatively associated with the TG level (P<0.0001) and positively associated with the HDL-c level (P<0.0001). For each 1-mmol/l increase in TG, LDL diameter fell by 0.281 nm. Conversely, for each 1-mmol/l increase in HDL-c, LDL diameter rose by 1.175 nm. CONCLUSIONS: Higher TG and lower HDL-c levels are associated with smaller LDL particle diameter. Small-diameter LDL particles could contribute to early atherogenic processes in HIV-1-infected patients on cART.

High-sensitivity C-reactive protein levels fall during statin therapy in HIV-infected patients receiving ritonavir-boosted protease inhibitors.

HIV-infected patients are at an increased risk of developing cardiovascular disease. Elevated levels of C-reactive protein (CRP) are associated with an increased risk of cardiovascular disease in the general population and are reduced by statin therapy. We examined the effect of pravastatin and rosuvastatin on CRP levels in 58 dyslipidemic HIV-infected patients. A 45-day course of either statin reduced the median CRP level from 3.0 to 2.4 mg/l (P < 0.001) with no correlation with changes in lipid parameters.

Rosuvastatin versus pravastatin in dyslipidemic HIV-1-infected patients receiving protease inhibitors: a randomized trial.

BACKGROUND: HIV infection and its treatment with protease inhibitors, especially when boosted with ritonavir, can cause lipid disorders. Statins, with the exception of fluvastatin, pravastatin and rosuvastatin, interact with protease inhibitor metabolism via CYP450. Pravastatin is recommended for patients with protease inhibitor-associated dyslipidemia. Rosuvastatin is the statin most effective on low-density lipoprotein cholesterol (LDL-c) in non-HIV patients. METHODS: HIV-1-infected patients treated with boosted protease inhibitor were randomized to receive either rosuvastatin 10 mg/day or pravastatin 40 mg/day for dyslipidemia (LDL-c >4.1 mmol/l and triglycerides <8.8 mmol/l). The percentage change in LDL-c, triglyceride and high-density lipoprotein-cholesterol levels, measured in a central laboratory, was determined after 45 days of statin treatment. RESULTS: Eighty-eight patients were randomized and 83 took the study drugs, 41 rosuvastatin and 42 pravastatin. The median duration of prior antiretroviral treatment was 9 years. At baseline, the median LDL-c level was 4.93 mmol/l, the triglyceride level 2.29 mmol/l, and the high-density lipoprotein-cholesterol level 1.27 mmol/l. The median percentage changes in the rosuvastatin and pravastatin arms were -37 and -19% for LDL-c (P < 0.001), respectively, and -19 and -7% for triglycerides (P = 0.035), respectively. The change in the high-density lipoprotein-cholesterol level was not significantly different between the two arms. None of the four severe adverse events was attributed to the statins; in particular, there were no renal, hepatic or muscular events. CONCLUSION: Rosuvastatin 10 mg/day was more effective than pravastatin 40 mg/day on LDL-c and triglyceride levels in HIV-1-infected patients receiving a boosted protease inhibitor.
