Anorectal Lymphogranuloma Venereum in Madrid: A Persistent Emerging Problem in Men Who Have Sex With Men.

BACKGROUND: Since 2003, outbreaks of lymphogranuloma venereum (LGV) with anorectal syndrome have been increasingly recognized in many Western countries. All of them have been classified as LGV serovar L2b, mainly occurring in human immunodeficiency virus (HIV)-infected men who have had sex with men (MSM). We describe a series of 26 diagnosed cases of LGV proctitis in downtown Madrid, Spain, in 2014, after implementing routine diagnostic procedures for this disease in symptomatic MSM. METHODS: We conducted an observational study of patients with symptomatic proctitis attending an outpatient infectious diseases clinic in Madrid, Spain during calendar year 2014. Clinical, epidemiological, laboratory, and therapeutic data were gathered and analyzed. RESULTS: Twenty-six patients were included in the analysis. All were MSM, and 24 of them were HIV-positive. All patients reported having acute proctitis symptoms including tenesmus (85%), pain (88%), constipation (62%), or anal discharge (96%). Proctoscopy showed mucopurulent exudate (25 patients [96%]), and rectal bleeding, with mucosal erythema and/or oedema in all cases. Rectal swabs were obtained from all patients, and LGV serovar L2 was confirmed in all of them. The cure rate was 100% after standard treatments with doxycycline 100 mg twice per day for 3 weeks. Simultaneous rectal infections with other sexually transmitted pathogens (gonorrhoea, herpes simplex virus, Mycoplasma genitalium) and systemic sexually transmitted diseases (STDs) (syphilis, acute HIV, and hepatitis C infections) were also documented in 12 patients (46%), but these co-infections did not appear to influence the clinical manifestations of LGV. CONCLUSIONS: Anorectal LGV is a common cause of acute proctitis and proctocolitis among HIV-infected MSM who practice unprotected anal sex, and it is frequently associated with other rectal STDs. The implementation of routine screening and prompt diagnosis of these rectal infections should be mandatory in all clinical settings attended by HIV and STD patients.

Meningoencefalitis criptocócica. Epidemiología y factores de riesgo de mortalidad en la era pre- y pos-TARGA / Cryptococcal meningoencephalitis. Epidemiology and mortality risk factors in pre- and post-HAART era

Introducción y objetivo: La meningoencefalitis criptocócica (MC), aunque infrecuente, sigue siendo una importante causa de morbimortalidad en pacientes con sida. Material y métodos: Revisión de los casos de MC en un hospital universitario (1990-2014). El diagnóstico se determinó mediante el aislamiento de Cryptococcus neoformans en el LCR. Se analizó la morbimortalidad temprana (< 12 semanas) y tardía (3-18 meses). Resultados: Se analizaron 32 pacientes de los 2.269 diagnósticos de sida (1,41%): 10 entre 1990-1996 y 22 entre 1997-2014. El antígeno criptocócico en el LCR fue positivo en todos los casos, con títulos > 1.024 en 19 pacientes (63%), presentando este grupo unos recuentos de CD4+ menores (40 ± 33 frente a 139 ± 78 cél/μl) y mayor afectación diseminada que el resto. Tras el primer episodio de MC la tasa de recaídas fue del 34%. La mortalidad global fue del 28% (9/32), muy superior en el período pre-TARGA. Conclusiones: La morbimortalidad de la MC viene determinada por padecer una inmunodeficiencia grave, la presencia de enfermedad diseminada, títulos elevados de antígeno en el LCR y el retraso en el inicio del TARGA (AU)

Introduction and objective: Cryptococcal meningoencephalitis (CM) is an uncommon entity, but remains a major cause of morbidity and mortality in patients with AIDS. Material and methods: Review of CM cases in a university hospital. The diagnosis was determined by isolation of Cryptococcus neoformans in cerebrospinal fluid. Morbidity and mortality was assessed at 12 weeks (early mortality) and between 3 and 18 months after diagnosis (late mortality). Results: We analyzed 32 patients from 2,269 AIDS cases (1.41%). 10 patients between 1990-1996 and 22 between 1997-2014. Cryptococcal antigen in CSF was positive in all cases, with titers > 1,024 in 19 patients (63%); this group had lower CD4+ counts (40 ± 33 vs. 139 ± 78 cel/μL) and greater disseminated involvement. After a first CM episode the relapse rate was 34%. Global mortality rate was 28% (9/32), much higher in the pre-HAART era. Conclusions: CM morbidity and mortality is related to severe immunodeficiency, disseminated disease, high titers of antigen in CSF and delayed initiation of HAART (AU)

Prácticas y percepción del riesgo en hombres con infección por el virus de la inmunodeficiencia humana que tienen sexo con otros hombres / Practices and perception of risk in human immunodeficiency virus infected males who have sex with other males

INTRODUCCIÓN: La incidencia de virus de la inmunodeficiencia humana (VIH) y otras enfermedades de transmisión sexual aumenta en hombres que tienen sexo con hombres (HSH) a pesar del conocimiento sobre cómo prevenirlas. Determinar los mecanismos que estarían motivando el fracaso de la prevención es importante para reconducir la tendencia. PACIENTES Y MÉTODOS: Con objeto de conocer las prácticas y conductas sexuales de riesgo así como las percepciones y valoraciones de los pacientes respecto a dicho riesgo, se realizaron encuestas anónimas, voluntarias y autoadministradas a HSH VIH+ que acudían a una consulta hospitalaria, que incluía 58 preguntas divididas en 10apartados para explorar conocimientos, actitudes y comportamientos frente al VIH. También se pasaron encuestas a médicos con objeto explorar sus percepciones, actitudes y opiniones respecto a la situación de la epidemia, prevención, percepción de la enfermedad y del paciente; y valores en la práctica clínica. RESULTADOS: Se analizaron 495encuestas a pacientes. El 87% dijeron conocer la manera de adquirir VIH y el 97% sabía cómo evitarlo, pero el 69% reconocía estar en situación de riesgo y el 43% se sentían poco preocupados de contraer VIH. El 65% tenían relaciones sexuales con ≥ 2 personas en un mismo día, el 47% encuentros por Internet y 26% sexo en grupo. El 65% de los encuestados consideraron que actuaban con impulsividad. Señalaron falta de información (33%), mala suerte (32%), riesgo excesivo asumido (36%) y despreocupación (25%) como motivos principales de la adquisición de la infección. Ante el diagnóstico, el 41% respondieron «nunca pensé que me pudiera pasar a mí» y el 32% respondieron «tuve mala suerte». De los 121 médicos encuestados, 24% consideraron que la infección por VIH/sida estaba fuera de control en España y el 65% respondieron que se tenía respecto a VIH/sida la imagen de enfermedad controlada y poco preocupante. El 71% de los encuestados juzgaron que el aumento de nuevas infecciones evidenciaba que no se tenía un plan preventivo adecuado. CONCLUSIONES: La gestión del riesgo de adquirir VIH se hace desde un grado de preocupación bajo, motivado por el optimismo fruto de los avances en la lucha contra la enfermedad y la dulcificación actual del discurso. La banalización del riesgo, al desvirtuar la idea de conducta arriesgada, es un determinante de actitudes que imposibilitarían adoptar un comportamiento preventivo eficaz y tomar decisiones prudentes y anticipadas

INTRODUCTION: The incidence of human immunodeficiency virus (HIV) and other sexually transmitted diseases increases in males who have sex with males (MSM), despite the knowledge on how to prevent them. To determine the mechanisms that are driving this lack of prevention is important to reverse the trend. PATIENTS AND METHODS: An anonymous, voluntary and self-reporting questionnaire was completed by HIV+ MSM patients who were seen in a hospital clinic, with the aim of finding out the sexual risk practices and behaviour, as well as their perceptions and assessment as regards this risk. The questionnaire included 58 questions, divided into 10sections, to explore the knowledge, attitudes, and behaviour as regards HIV. The questionnaires were also given to the physicians, with the aim of exploring their perceptions, attitudes and opinions as regards the situation of the epidemic, prevention, perception of the diseases and the patient, and values in clinical practice. RESULTS: A total of 495 questionnaires from the patients were analysed. Most of them (87%) said they knew how HIV was acquired, and 97% knew how to prevent it, but 69% knew they were in a risk situation, and 43% had little concern of contracting HIV. Almost two-thirds (65%) had sex with ≥2 persons on the same day, 47% met on the Internet and 26% had group sex. The same percentage of those surveyed considered that they acted impulsively. They highlighted a lack of information (33%), bad luck (32%), assumed excessive risk (36%), and lake of concern (25%), as the main reasons for acquiring the infection. When confronted with diagnosis 41% of patients answered «I never thought that it would happen to me», and 32% said «I had bad luck». Of the 121 physicians who completed the questionnaire, 24% considered that infection due to HIV/AIDS was out of control in Spain, and 65% responded that there was an image that HIV/AIDS was a controlled disease and of little concern. A large majority (71%) of those surveyed, considered that the increase in new infections showed that there was no suitable preventive plan. CONCLUSIONS: The management of the risk of acquiring HIV maintains a low level of concern, due to the optimism produced by the advances in the fight against the disease and the current toning down of the discussion. The trivialisation of the risk, on distorting the idea of risky behaviour, is a determining factor of attitudes that makes it impossible to adopt effective preventive behaviour and to take sensible and anticipated decisions

Corynebacterium striatum: an emerging nosocomial drug-resistant endocardial pathogen.

Endocarditis due to Corynebacterium striatum has been rarely reported. A 78-year-old patient developed pacemaker endocarditis caused by multidrug-resistant C. striatum, complicated by vertebral osteomyelitis and epidural abscess. Daptomycin therapy successfully eradicated the bacteremia and metastatic infection. A review of the English literature on this emerging nosocomial, multidrug-resistant pathogen is included.

Infective endocarditis at autopsy: a review of pathologic manifestations and clinical correlates.

The frequency of autopsies appears to be declining, and the usefulness has been challenged. We reviewed cases of autopsied active infective endocarditis (IE) during 2 periods based on the availability of high-tech 2-dimensional echocardiograms: Period 1 (P1) included 40 cases studied from 1970 to 1985, and Period 2 (P2) included 28 cases seen from 1986 to 2008--that is, before and after the introduction of echocardiograms in our institution. We conducted the study to reassess the pathology of IE and to determine how frequently diagnosis is not made during life.The age of patients increased 10 years on average between the 2 periods, and comorbidities were significantly more frequent in P2. While the frequency of rheumatic valve disease and prosthetic valve endocarditis (PVE) decreased, degenerative valve disease increased. Isolated mitral or aortic valve IE was most common. Right-sided IE was observed in patients with Staphylococcus aureus bacteremia from infected venous lines. In most cases IE involved only the cusps of cardiac valves. "Virulent" microorganisms caused ulcerations, rupture, and perforation of the cusps and necrosis of chordae tendiniae and perivalvular apparatus. In PVE the lesions were located behind the site of attachment, and vegetations were seen on the sewing ring in both metallic and biologic prostheses. Infection spread to adjacent structures and myocardium with ring abscess observed in 88% of cases. Prosthetic detachment causing valve regurgitation was associated with abscesses in 76% of cases; these patients developed persistent sepsis and severe cardiac failure. Obstruction occurred in patients with PVE of the mitral valve. Acute purulent pericarditis was observed in 22% of cases, mainly in patients with aortic valve IE and myocardial abscesses.Gross infarcts were seen in 63% of cases but were asymptomatic in most instances. The spleen, kidneys, and mesentery were the sites most frequently involved. Myocardial infarctions were found in less than 10% of cases. Abscesses were also frequently found and were a common source of persistent fever and bacteremia. Glomerulonephritis was more common in the first period. Brain pathology consisted of ischemic and hemorrhagic infarcts and abscesses. Cerebral bleeding was more frequent in patients with PVE on anticoagulant therapy. Neutrophilic meningitis was observed in S. aureus IE.Diagnosis of IE was not made during life in 14 (35%) cases during P1 and 12 (42.8%) cases in P2. Overall, diagnosis was missed until autopsy in 38.2% of cases. IE was hospital acquired in 28 instances. While a clinical diagnosis was made in all but 4 cases of early-onset PVE (23.5%), the diagnosis was not made during life in 22 of 51 patients with native-valve IE (43.1%). Of these 22 patients, IE was hospital acquired in 11 (50%). The absence of fever, cardiac murmurs, and many of the typical stigmata of endocarditis may have led to the diagnosis being overlooked clinically.Brain bleeding, cardiac failure and less frequently acute myocardial infarct were the most common causes of death.IE continues to be missed frequently until autopsy. Postmortem examination is an important tool for evaluating the quality of care, and for guiding teaching and research related to cardiovascular infections.

Pulmonary infectious diseases in patients with primary immunodeficiency and those treated with biologic immunomodulating agents.

PURPOSE OF REVIEW: Lung infectious disease is an important cause of morbidity and mortality in patients with primary immunodeficiencies and other conditions that alter immunologic mechanisms against microbial invasion. Lung infectious diseases occurring in patients with congenital immunodeficiency and patients on treatment with biologic anti-inflammatory compounds are discussed. Understanding of the complex relationships between the immune system and microbes is of paramount importance for timely diagnosis and successful treatment of lung infectious diseases in this group of immunocompromised hosts. RECENT FINDINGS: In the past, only a minority of children with severe primary immunodeficiency survived beyond childhood and these disorders were within the scope of the pediatrician. As modern prophylaxis and treatment strategies have been implemented, these patients will now survive into adulthood. Nowadays, therapy with new biologic compounds--tumor necrosis factor (TNF) blockers and anti-CD20 drugs--that disrupt antimicrobial surveillance and the control of intracellular microorganisms such as mycobacteria, fungi and viruses has been associated with the emergence of a new population at risk for the development of severe pulmonary and disseminated infectious diseases. SUMMARY: A wide array of bacteria, viruses, fungi and protozoa may cause severe pulmonary infectious diseases in patients with primary immunodeficiency and patients on treatment with anti-TNF and anti-CD20 drugs. Knowledge of the association of certain microbial agents with specific immune disturbances is of great clinical interest.

Spontaneous epidural abscess: analysis of 15 cases with emphasis on diagnostic and prognostic factors.

PURPOSE: To describe the incidence and characterize the clinical manifestations, diagnosis and outcome of spontaneous epidural abscess (SEA) not associated with neurosurgical procedures or instrumentation of the spine. METHODS: Review of cases of SEA over 10 years. Diagnosis was made by imaging-techniques and surgical examination. RESULTS: Fifteen patients were studied. The incidence of SEA was 0.4 cases per 100,000 person-years. Infection gained access to the epidural space haematogenously in 9 patients (60%). SEA was located at the lumbar (7 cases), cervical (4), cranial (2) and thoracic (1) areas. Local pain was the most common manifestation (93.3%); fever was absent in 40%. One third did not show neurologic abnormalities. Staphylococcus aureus was the most commonly isolated agent (87% of cases). All the patients received antimicrobial therapy for a mean period of 6.1+/-3.9 weeks. In addition, open surgical drainage or CT-guided needle aspiration was successfully performed in 10 and 3 patients respectively. Two patients were managed with antibiotics alone. Poor outcome occurred more frequently in patients with abscess at higher levels (67% in cranial or cervical abscesses versus 0% in thoracic or lumbosacral abscesses). An association was found between delayed diagnosis and poor outcome (p<0.05). Overall, 54% of our patients recovered without sequelae. CONCLUSIONS: SEA resulted from the extension of nearby or distant infections into the epidural space. Diagnosis was frequently delayed and the patient's neurologic status at presentation was the most important predictor of the outcome. The onset of spinal pain in patients with focal infections should prompt MRI of the spine, even in the absence of neurologic abnormalities or fever.

Nodular lung schistosomiais lesions after chemotherapy for dysgerminoma.

We report an unusual case of pulmonary schistosomiasis in a traveler to Mali that was diagnosed 16 months after primary infection, one month after she finished chemotherapy for a malignant tumor. Serologic analysis showed marked eosinophilia. Our case emphasizes the need to detect parasitic infections in cancer patients with unexplained eosinophilia, particularly in immigrants and travelers to tropical countries.

Endocarditis caused by Staphylococcus aureus: A reappraisal of the epidemiologic, clinical, and pathologic manifestations with analysis of factors determining outcome.

Staphylococcus aureus is the leading cause of infectious endocarditis and its mortality has remained high despite better diagnostic and therapeutic procedures over time. We conducted a retrospective review of 133 cases of definite S. aureus endocarditis seen at a single tertiary care hospital over 22 years to assess changes in the epidemiology and incidence of the infection, manifestations, outcome, risk factors for mortality, and impact of cardiac surgery on prognosis.Patients were classified into 2 groups: 1) right-sided endocarditis (64 patients) and 2) left-sided endocarditis (69 patients). While the number of cases of left-sided endocarditis remained steady at 1-3 cases per 10,000 admissions, the incidence of right-sided endocarditis, after a peak in the early 1990s, declined to almost disappear in 2001. Among the cases of right-sided endocarditis, we found 2 subsets of patients with different clinical features and prognosis: the first subset comprised 53 intravenous drug abusers, and the second subset comprised 11 patients with catheter-associated S. aureus bacteremia and endocarditis. Fifty-one patients were human immunodeficiency virus (HIV)-positive drug abusers, most of whom (80.3%) had right-sided endocarditis. We did not find differences in mortality between HIV-positive and HIV-negative individuals; mortality seemed to depend more on the site of the heart involved than on HIV status.Among the cases of left-sided endocarditis, the mitral valve was more commonly involved than the aortic valve (61% vs. 30%). Overall, 74% of patients with left-sided endocarditis developed 1 or more cardiac or extracardiac complication. In comparison, only 23.4% of patients with right-sided endocarditis developed complications.Prosthetic valve endocarditis (PVE) was hospital-acquired more frequently than native valve endocarditis (NVE). Patients with PVE had a shorter duration of symptoms until diagnosis and presented with or developed cardiac murmurs less frequently than patients with NVE. Cardiac failure (49%), renal failure (43%) and central nervous system (CNS) events (35%) were frequently observed in patients with both PVE and NVE. Valve replacement was more frequently needed and more rapidly performed in patients with PVE than in their counterparts with NVE.The overall mortality of patients with right-sided endocarditis was 17%. While the mortality of right-sided endocarditis in injection drug users was 3.7%, the mortality of patients with right-sided endocarditis associated with infected intravenous catheters was 82% (odds ratio [OR], 0.01; 95% confidence interval [CI], 0.001-0.07). For left-sided endocarditis mortality was 38% and was not significantly different in patients with NVE or PVE (OR, 0.65; 95% CI, 0.23-1.87). CNS complications were associated with mortality in both NVE (OR, 6.55; 95% CI, 1.78-24.04) and PVE (OR, 32; 95% CI, 2.63-465.40). Development of 2 or 3 complications was associated with an increased risk of mortality (OR, 5.59; 95% CI, 1.08-28.80 and OR, 9.25; 95% CI, 1.36-62.72 for 2 vs. 1 complication and for 3 vs. 2 complications, respectively).Surgical treatment did not significantly influence mortality in cases of NVE, (OR, 3.19; 95% CI, 0.76-13.38) but significantly improved the prognosis of patients with PVE (OR, 69; 95% CI, 2.89-1647.18).S. aureus endocarditis is an aggressive, often fatal, infection. The results of the current study suggest that valve replacement will improve the outcome of infection, particularly in patients with PVE.

Long term failure of miltefosine in the treatment of refractory visceral leishmaniasis in AIDS patients.

We carried out a retrospective and descriptive study of 4 HIV infected patients with relapsing visceral leishmaniasis (VL) seen at 2 tertiary-care hospitals in Spain during the last 6 y, in whom miltefosine was used as a compassionate use treatment at a dosage of 50 mg b.i.d. Patients had a medium CD4 lymphocyte count of 69 cells/microl and were C stage. All patients received at least 2 different anti-leishmanial drugs and had at least 3 relapses before miltefosine treatment (range 3-7). Three patients were treated with miltefosine at a standard dose of 50 mg b.i.d. for 28 d, and the other during 12 months. Despite an initial symptomatic improvement, miltefosine treatment failed to eradicate the infection in all cases. We conclude that the use of miltefosine alone is not strong enough to cure relapsing VL in HIV-1 controlled infected patients.
