Higher Dose Oral Fluconazole for the Treatment of AIDS-related Cryptococcal Meningitis (HIFLAC)-report of A5225, a multicentre, phase I/II, two-stage, dose-finding, safety, tolerability and efficacy randomised, amphotericin B-controlled trial of the AIDS Clinical Trials Group.

BACKGROUND: The WHO recommended 1200mg/day of fluconazole (FCZ) in the induction phase of cryptococcal meningitis (CM) in HIV prior to 2018 in regions where amphotericin-B (AMB) was unavailable. A 2-stage AMB-controlled, dose-escalation study to determine the maximum tolerated dose and the safety/efficacy of an induction-consolidation strategy of higher doses FCZ (1200mg-2000mg/day), adjusted for weight and renal function (eGFR)in adults with CM was undertaken. METHODS: In Stage-1, three induction doses of FCZ (1200mg/day, 1600mg/day and 2000mg/day) were tested in sequential cohortsand compared with AMB in a 3:1 ratio. A particular dose was not tested in Stage 2 if there were significant predetermined safety or efficacy concerns. In Stage-2, the 1200mg dose was excluded per protocol because of increased mortality, and participants were randomised to 1600mg, 2000mg FCZ or AMB in a 1:1:1 ratio. FINDINGS: One hundred and sixty eight participants were enrolled with 48, 50, and 48 in the AMB, 1600mg and 2000mg cohorts. The Kaplan Meier proportion for mortality (90% CI) at 10 and 24 weeks for AMB was 17% (10, 29) and 24% (15, 37), compared to 20% (12, 32) and 30% (20, 43) for 1600mg, and 33% (23, 46) and 38% (27, 51) for 2000mg/day FCZ. With the exception of a higher incidence of gastrointestinal side effects in the 2000mg cohort, both induction doses of FCZ were safe and well tolerated. There were no life-threatening changes in electrocardiogram QTc which were similar across all doses of FCZ and AMB. The median (IQR) change in log10 cryptoccal colony forming units (CFU) from week 0 to week 2 was -8(-4.1,-1.9) for AMB; -2.5(-4.0, -1.4) for 1600mg FCZ and -8 (-3.2, -1.0) for 2000mg FCZ. The proportion (90% CI) CSF CM negative at 10 weeks was 81%(71,90) for AMB; 56%(45,69) for 1600mg FCZ and 60%(49,73) for 2000mg FCZ. INTERPRETATION: Induction phase weight and renal-adjusted doses of 1600mg and 2000mg/day FCZ for CM were safe and well tolerated except for increased GI side effects in the 2000mg/day dose, and had similar times to achieve CSF sterilization, but took significantly longer than AMB. The WHO recommended 1200mg FCZ was associated with a high mortality. While not statistically significant, mortality was numerically lower in the AMB compared to 1600mg and 2000mg FCZ These data make a case for a phase 3 study of higher doses of FZC.

Pro-Inflammatory Alterations of Circulating Monocytes in Latent Tuberculosis Infection.

Background: Latent tuberculosis infection (LTBI) has been associated with increased cardiovascular risk. We investigated the activation and pro-inflammatory profile of monocytes in individuals with LTBI and their association with coronary artery disease (CAD). Methods: Individuals 40-70 years old in Lima, Peru, underwent QuantiFERON-TB testing to define LTBI, completed a coronary computed tomography angiography to evaluate CAD, and provided blood for monocyte profiling using flow cytometry. Cells were stimulated with lipopolysaccharide to assess interleukin-6 (IL-6) and tumor necrosis factor (TNF)-α responses. Results: The clinical characteristics of the LTBI (n = 28) and non-LTBI (n = 41) groups were similar. All monocyte subsets from LTBI individuals exhibited higher mean fluorescence intensity (MFI) of CX3CR1 and CD36 compared with non-LTBI individuals. LTBI individuals had an increased proportion of nonclassical monocytes expressing IL-6 (44.9 vs 26.9; P = .014), TNF-α (62.3 vs 35.1; P = .014), and TNF-α+IL-6+ (43.2 vs 36.6; P = .042). Among LTBI individuals, CAD was associated with lower CX3CR1 MFI on classical monocytes and lower CD36 MFI across all monocyte subsets. In multivariable analyses, lower CD36 MFI on total monocytes (b = -0.17; P = .002) and all subsets remained independently associated with CAD in LTBI. Conclusions: Individuals with LTBI have distinct monocyte alterations suggestive of an exacerbated inflammatory response and tissue migration. Whether these alterations contribute to cardiovascular disease pathogenesis warrants further investigation.

[Disseminated histoplasmosis and haemophagocytic syndrome in HIV patients: A case series in a Peruvian hospital]. / Histoplasmosis diseminada y síndrome hemofagocítico en pacientes VIH: serie de casos en un hospital peruano.

BACKGROUND: Disseminated histoplasmosis (DH) is an opportunistic fungal infection in severely immunocompromised patients with HIV infection. Haemophagocytic syndrome (HFS), which can occur in these co-infected patients when the immune response is significantly altered, is often associated with high mortality. AIMS: To describe the epidemiological, clinical, analytical and microbiological characteristics, along with studying the presence of HFS, in patients with DH-HIV. METHODS: A retrospective study was conducted on a case series using data from the clinical records of patients diagnosed with DH and HIV infection during the years 2014 and 2015. RESULTS: DH was diagnosed in 8 (1.3%) of 597 HIV patients. All patients were in stage C3, and 75% (6/8) were not receiving combined antiretroviral therapy (CART). The remaining two patients had recently begun CART (possible immune reconstitution syndrome). Five (62.5%) of the 8 patients met criteria for HFS. The most frequent clinical symptoms were lymphoproliferative and consumptive syndrome, respiratory compromise, and cytopenia. Histoplasma was isolated in lymph nodes of 75% (6/8) of the patients, in blood samples in 25% (2/8), and also in intestinal tissue in one patient. The antifungal therapy was amphotericin B deoxycholate, without adjuvants. The overall mortality was 50%. CONCLUSIONS: In this case series, DH-HIV co-infection frequently progressed to HFS with high mortality. The clinical picture may resemble that of other systemic opportunistic infections, such as tuberculosis, or can take place simultaneously with other infections. Clinical suspicion is important in patients with severe cytopenia and lymphoproliferative and consumptive syndrome in order to establish an early diagnosis and prescribing a timely specific therapy.

Mortality in hospitalized patients with tuberculous meningitis.

BACKGROUND: To evaluate the mortality in hospitalized patients with tuberculous meningitis and describe factors associated with an increased risk of mortality. METHODS: Retrospective study of hospitalized patients with tuberculous meningitis between 2006 and 2015 in Peru performing a generalized linear regression to identify factors predictive of in-hospital mortality. RESULTS: Of 263 patients, the median age was 35 years, 72.6% were men, 38% were positive for HIV upon admission, 24% had prior TB infections and 2.3% had prior MDR-TB infections. In-hospital mortality was 30.4% of all study patients with a final diagnosis of TBM. When multivariable analysis was applied, significant associations with in-hospital mortality were seen among patients with HIV (RR 2.06; Confidence Interval 95% (95% CI) 1.44-2.94), BMRC II (RR 1.78; 95% CI 1.07-2.97), BMRC III (RR 3.11; 95% CI 1.78-5.45) and positive CSF cultures (RR 1.95; 95% CI 1.39-2.74). CONCLUSIONS: In-hospital mortality is higher among patients with HIV infections, age over 40 years, positive CSF TB culture and BMRC stage II or III.

Caminando junto a la tuberculosis / Walking with tuberculosis

En países con elevada endemia tuberculosa, las personas están muy cerca a esta enfermedad a lo largo de toda su vida. Sea porque algún familiar o amigo desarrolla la enfermedad o porque en el devenir de la vida experimenta la infección o la enfermedad. En el caso del médico o profesional de la salud, seguramente su cercanía será mayor, y preferentemente si se dedica a actividades de prevención y control en tuberculosis. En este artículo se exponen las experiencias cercanas con la tuberculosis desde nuestra infancia, como estudiante de medicina, médico, investigador, salubrista y docente universitario, donde el profesional pasa situaciones afectivas personales, temas de limitaciones de conocimiento, limitaciones en el diagnóstico, hasta ejecución de investigaciones sobre problemas locales y generando respuestas en la prevención y control. Seguramente es una experiencia común en profesionales de salud que en el día a día enfrentan esta endemia, de la cual cada vez conocemos más, pero se nos hace muy difícil su control.

In countries with high tuberculosis endemicity, people are very close to this disease throughout their lives. This may be because a relative or friend develops the disease, or because in the course of their lives they themselves acquire the infection or illness. In the event, that the person is a doctor or a health professional their contact with tuberculosis will be greater, and even more so if they are involved in activities relating to its prevention and control. This article discusses my experiences with tuberculosis since childhood, as a medical student, doctor, researcher, health professional and university professor, where the professional navigates situations of a personal or emotional nature, knowledge limitations, diagnostic constraints, and even undertaking research on local problems and generating responses in prevention and control. It is surely, a common experience among health professionals who each day face this endemic which we increasingly know more about, yet it remains very difficult to control.

Latent tuberculosis infection is associated with increased unstimulated levels of interferon-gamma in Lima, Peru.

BACKGROUND: We previously reported increased unstimulated blood levels of interferon-gamma in persons with latent tuberculosis infection (LTBI) in the United States, suggesting enhanced immune activation in LTBI. To investigate this further in a TB-endemic setting, we assessed interferon-gamma levels in persons with and without LTBI in Peru. METHODS: We analyzed data from patients with and without a recent type 1 (spontaneous) acute myocardial infarction (AMI) who were enrolled from two public hospital networks in Lima, Peru, and underwent LTBI testing using the QuantiFERON® TB Gold In-tube (QFT) assay. Participants with a positive QFT test were defined as having LTBI, whereas participants with a negative QFT test were defined as non-LTBI. Unstimulated interferon-gamma was quantified via enzyme-linked immunosorbent assay in the QFT nil-tube, which does not contain antigens. We compared unstimulated interferon-gamma levels between LTBI and non-LTBI groups using the Wilcoxon rank sum test. We used proportional odds modeling for multivariable analysis. RESULTS: Data from 214 participants were included in this analysis. Of those, 120 (56%) had LTBI. There were no significant differences in age, sex and comorbidities between LTBI and non-LTBI participants, except for recent AMI that was more frequent in LTBI. LTBI participants had higher unstimulated interferon-gamma levels compared to non-LTBI participants (median, interquartile range; 14 pg/mL, 6.5-52.8 vs. 6.5 pg/mL, 4.5-15; P<0.01). LTBI remained associated with higher unstimulated interferon-gamma levels after controlling for age, sex, recent AMI, history of hypertension, diabetes mellitus, dyslipidemia, end stage renal disease, malignancy, obesity, and tobacco use (adjusted odds ratio, 2.93; 95% confidence interval, 1.8-4.9). In a sensitivity analysis that excluded participants with AMI, the association between unstimulated interferon-gamma and LTBI remained present (adjusted odds ratio; 3.93; 95% confidence interval, 1.9-8.2). CONCLUSIONS: LTBI was associated with higher unstimulated interferon-gamma levels. These data suggest ongoing immune activation in LTBI.

Monotypic low-level HIV viremias during antiretroviral therapy are associated with disproportionate production of X4 virions and systemic immune activation.

OBJECTIVE: During effective antiretroviral therapy (ART), low-level plasma viremias (LLV) (HIV RNA >30-1000 copies/ml) can be detected intermittently. We hypothesized that systemic inflammation is associated with LLV either as the cause or result of the production of virions from clonally expanded cells. METHODS: Prospective cohort study of HIV-infected ART-naive Peruvians enrolled prior to ART and followed for 2 years. Plasma HIV RNA and peripheral blood mononuclear cell (PBMC) HIV DNA concentrations were quantified pre-ART from individuals whose plasma HIV RNA was ART-suppressed. Inflammatory biomarker concentrations were measured pre and during ART. Single-genome amplification (SGA) derived HIV env and pol genotypes from pre-ART and LLV specimens. Antiretroviral levels during ART assessed adherence. Statistical associations and phylogenetic relationships were examined. RESULTS: Among 82 participants with median plasma HIV RNA less than 30 copies/ml, LLV were detected in 33 of 82 (40%), with a LLV median HIV RNA of 73 copies/ml. Participants with vs. without LLV had significantly higher pre-ART plasma HIV RNA (P < 0.001) and PBMC HIV DNA (P < 0.007); but, during ART, their antiretroviral drug levels were similar. LLV env sequences were monotypic in 17 of 28 (61%) and diverse in 11 of 28 (39%) participants. Those with the monotypic vs. diverse LLV pattern had elevated hsCRP and sCD163 (P = 0.004) and LLV with more X4 variants (P = 0.02). CONCLUSION: In individuals with monotypic LLV sequences, higher levels of pre-ART HIV DNA and RNA, systemic inflammation and X4 viruses suggest an interaction between inflammation and the production of virions from proliferating infected cells, and that naïve T cells may be a source of LLV.

Cough Frequency During Treatment Associated With Baseline Cavitary Volume and Proximity to the Airway in Pulmonary TB.

BACKGROUND: Cough frequency, and its duration, is a biomarker that can be used in low-resource settings without the need of laboratory culture and has been associated with transmission and treatment response. Radiologic characteristics associated with increased cough frequency may be important in understanding transmission. The relationship between cough frequency and cavitary lung disease has not been studied. METHODS: We analyzed data in 41 adults who were HIV negative and had culture-confirmed, drug-susceptible pulmonary TB throughout treatment. Cough recordings were based on the Cayetano Cough Monitor, and sputum samples were evaluated using microscopic observation drug susceptibility broth culture; among culture-positive samples, bacillary burden was assessed by means of time to positivity. CT scans were analyzed by a US-board-certified radiologist and a computer-automated algorithm. The algorithm evaluated cavity volume and cavitary proximity to the airway. CT scans were obtained within 1 month of treatment initiation. We compared small cavities (≤ 7 mL) and large cavities (> 7 mL) and cavities located closer to (≤ 10 mm) and farther from (> 10 mm) the airway to cough frequency and cough cessation until treatment day 60. RESULTS: Cough frequency during treatment was twofold higher in participants with large cavity volumes (rate ratio [RR], 1.98; P = .01) and cavities located closer to the airway (RR, 2.44; P = .001). Comparably, cough ceased three times faster in participants with smaller cavities (adjusted hazard ratio [HR], 2.89; P = .06) and those farther from the airway (adjusted HR, 3.61;, P = .02). Similar results were found for bacillary burden and culture conversion during treatment. CONCLUSIONS: Cough frequency during treatment is greater and lasts longer in patients with larger cavities, especially those closer to the airway.

The Relationship Between Latent Tuberculosis Infection and Acute Myocardial Infarction.

Background: Tuberculosis has been associated with an increased risk of cardiovascular disease (CVD), including acute myocardial infarction (AMI). We investigated whether latent tuberculosis infection (LTBI) is associated with AMI. Methods: We conducted a case-control study in 2 large national public hospital networks in Lima, Peru, between July 2015 and March 2017. Case patients were patients with a first time diagnosis of type 1 (spontaneous) AMI. Controls were patients without a history of AMI. We excluded patients with known human immunodeficiency virus infection, tuberculosis disease, or prior LTBI treatment. We used the QuantiFERON-TB Gold In-Tube assay to identify LTBI. We used logistic regression modeling to estimate the odds ratio (OR) of LTBI in AMI case patients versus non-AMI controls. Results: We enrolled 105 AMI case patients and 110 non-AMI controls during the study period. Overall, the median age was 62 years (interquartile range, 56-70 years); 69% of patients were male; 64% had hypertension, 40% dyslipidemia, and 39% diabetes mellitus; 30% used tobacco; and 24% were obese. AMI case patients were more likely than controls to be male (80% vs 59%; P < .01) and tobacco users (41% vs 20%; P < .01). LTBI was more frequent in AMI case patients than in controls (64% vs 49% [P = .03]; OR, 1.86; 95% confidence interval [CI], 1.08-3.22). After adjustment for age, sex, hypertension, dyslipidemia, diabetes mellitus, tobacco use, obesity, and family history of coronary artery disease, LTBI remained independently associated with AMI (adjusted OR, 1.90; 95% CI, 1.05-3.45). Conclusions: LTBI was independently associated with AMI. Our results suggest a potentially important role of LTBI in CVD.

Histological Examination in Obtaining a Diagnosis in Patients with Lymphadenopathy in Lima, Peru.

The differential diagnosis for lymphadenopathy is wide and clinical presentations overlap, making obtaining an accurate diagnosis challenging. We sought to characterize the clinical and radiological characteristics, histological findings, and diagnoses for a cohort of patients with lymphadenopathy of unknown etiology. 121 Peruvian adults with lymphadenopathy underwent lymph node biopsy for microbiological and histopathological evaluation. Mean patient age was 41 years (Interquartile Range 26-52), 56% were males, and 39% were HIV positive. Patients reported fever (31%), weight loss (23%), and headache (22%); HIV infection was associated with fever (P < 0.05) and gastrointestinal symptoms (P < 0.05). Abnormalities were reported in 40% of chest X-rays (N = 101). Physicians suspected TB in 92 patients (76%), lymphoma in 19 patients (16%), and other malignancy in seven patients (5.8%). Histological diagnoses (N = 117) included tuberculosis (34%), hyperplasia (27%), lymphoma (13%), and nonlymphoma malignancy (14%). Hyperplasia was more common (P < 0.001) and lymphoma less common (P = 0.005) among HIV-positive than HIV-negative patients. There was a trend toward reduced frequency of caseous necrosis in samples from HIV-positive than HIV-negative TB patients (67 versus 93%, P = 0.055). The spectrum of diagnoses was broad, and clinical and radiological features correlated poorly with diagnosis. On the basis of clinical features, physicians over-diagnosed TB, and under-diagnosed malignancy. Although this may not be inappropriate in resource-limited settings where TB is the most frequent easily treatable cause of lymphadenopathy, diagnostic delays can be detrimental to patients with malignancy. It is important that patients with lymphadenopathy undergo a full diagnostic work-up including sampling for histological evaluation to obtain an accurate diagnosis.

Obstrucción intestinal por Ascaris lumbricoides en un adulto mayor / Intestinal obstruction due to Ascaris lumbricoides infection in a geriatric patient

Ascaris lumbricoides is considered the largest intestinal nematode with a higher incidence in the childhood, representing a truly medical and public health problem, principally in undeveloped countries. We present the case of an 83 year old man, born and coming from the amazon region, without any relevant previous history of disease, admitted in the emergency department of our hospital for presenting intestinal obstruction and also presumptive biliary obstruction due to multiple balls of parasites, requiring immediate surgical intervention. We emphasize the need of consider this etiologic possibility in the differential diagnosis, that in this particular case, wasn't suspected in the first place.

Ascaris lumbricoides es considerado el nemátodo intestinal de mayor tamaño. Se presenta con mayor frecuencia en la infancia, representando un verdadero problema médico y de salud pública, especialmente en países en vías de desarrollo. Presentamos el caso de un varón de 83 años, natural y procedente de la región amazónica del Perú, sin antecedentes médicos de relevancia, que ingresa a Servicio de urgencias de nuestro hospital por un cuadro de obstrucción intestinal y presunta obstrucción biliar, requiriendo una intervención quirúrgica inmediata. El diagnóstico final de obstrucción intestinal por la presencia de múltiples ovillos de Ascaris lumbricoides, no fue considerado dentro de los diagnósticos diferenciales previo al acto quirúrgico.

Chikungunya: bending over the Americas and the rest of the world

Abstract Chikungunya is an arthropod-borne virus transmitted by Aedes mosquito bites. A viral mutation has allowed Aedes albopictus to become the preferred vector extending the geographic spread of the condition. The virus causes an acute febrile illness occasionally followed by a chronic rheumatic condition causing severe impairment. The diagnosis is usually confirmed with serology. No specific treatment is currently available. This article reviews the condition with emphasis on his dissemination in the Americas.

Rutas de transporte público y situación de la tuberculosis en Lima, Perú / Routes of public transport and the situation of tuberculosis in Lima, Peru

Con el objetivo de determinar la asociación entre el número de rutas formales de transporte público urbano y la situación de la tuberculosis (TB) en cada distrito de Lima, se realizó un análisis correlacional y un modelo de regresión lineal entre ambas variables. Asimismo, se determinó el número de rutas de transporte público de mayor probabilidad de transmisión de TB, las zonas de mayor circulación de dichas rutas y un mapeo de estas. Existe una correlación positiva entre el número de rutas formales que recorren cada distrito de Lima y la situación de TB; un porcentaje de la situación de TB podría ser explicada por el número de rutas de transporte público. De las 404 rutas formales que recorren Lima Metropolitana, 147 (36,4%) son rutas de mayor probabilidad de transmisión de TB. El transporte público debería ser considerado en la lucha actual contra la TB.

In order to determine the association between the number of formal urban public transport routes and the situation of tuberculosis (TB) in each district of Lima, a correlational analysis and linear regression model between the two variables was performed. Also determined were the number of public transport routes most likely to transmit TB, the areas of greatest activity of these routes and a mapping of these routes. There is a positive correlation between the number of formal routes through each district of Lima and the situation of tuberculosis; a percentage of the TB situation could be explained by the number of public transport routes. Of the 404 formal routes that run through Lima, 147 (36.4%) are routes of greater probability of transmission of TB. Public transport should be considered in the ongoing fight against TB.

[Recurrent diarrhea due to Cystoisopora belli in HIV/AIDS patients receiving HAART]. / Diarrea recurrente por Cystoisopora belli en pacientes con infección por VIH con TARGA.

The Cystoisospora belli, before denominated as Isospora belli, is the etiologic agent of cystoisosoporiasis, an opportunistic infection affecting immunocompromised patients, characterized by chronic diarrhea and weight loss. The incidence of chronic diarrhea for this agent, in HIV patients, has decreased considerably. This thanks to the advent of highly active antiretroviral therapy (HAART), which has improved the patient's immune response and decrease viral load. We present six cases of cystoisosoporiasis recurrent and refractory to treatment in HIV patients, who was being treated with with trimethoprim / sulfamethoxazole (TMP / SMX) orally as a prophylaxis. Five of these patients passed away due to the infection, despite of the fact that they had a good response to HAART (adequate increase in CD4 and viral load undetectable) and they had been treated with second line drugs.

Diarrea recurrente por Cystoisopora belli en pacientes con infección por VIH con TARGA / Recurrent diarrhea due to Cystoisopora belli in HIV/AIDS patients receiving HAART

La Cystoisospora belli, antes denominada Isospora belli, es el agente etiológico de la cystoisosporiasis, una infección oportunista que afecta a pacientes inmunodeprimidos, caracterizada por diarrea crónica y pérdida ponderal. La incidencia de diarrea crónica por este agente, en pacientes infectados por el VIH, ha disminuido considerablemente. Ello gracias al advenimiento de la terapia antirretroviral de gran actividad (TARGA), con la que se ha logrado mejorar la respuesta inmunológica del paciente y disminuir su carga viral. Se presentan seis casos de cystoisosporiasis recurrente y refractaria en pacientes con infección por VIH, en quienes se diagnosticó cystoisosporiasis pese a que previamente se encontraban recibiendo profilaxis con trimetropin/sulfametoxazol (TMP/SMX). Cinco de ellos evolucionaron de manera tórpida y fallecieron, a pesar de una buena respuesta al TARGA (adecuado incremento de CD4 y disminución de la carga viral hasta rangos indetectables), y de tratamiento con TMP/SMX por vía oral y otros medicamentos de segunda línea.

Probable transmisión vertical del virus de la influenza a (H1N1): a propósito de un caso / Probable vertical transmission of the influenza virus a (H1N1): apropos of a case

Se reporta el caso de un recién nacido varón, producto de embarazo de 36 semanas, con diagnóstico de neumonía congénita y examen confirmatorio de infección por el virus de la influenza A (H1N1), sin ningún otro tipo de contacto sospechoso. La madre ingresó al hospital con insuficiencia respiratoria y antecedente de proceso gripal de cinco días de evolución, durante los primeros días de la pandemia en el Perú. Por la evolución grave del proceso respiratorio, se le administró ventilación mecánica para luego ser sometida a cesárea por sufrimiento fetal agudo y oligoamnios. Se confirmó en la madre infección por el virus de la influenza A H1N1 epidémico y tuberculosis pulmonar.

We report the case of a male newborn, product of a 36 week pregnancy, with diagnosis of congenital pneumonia and with a confirmatory test for influenza A (H1N1) virus, without any other suspicious contact. The mother was admitted to the hospital with respiratory failure and the history of a flu-like episode of 5 days of evolution, during the first days of the pandemic in Peru. Due to the severe evolution of the respiratory process, assisted ventilation was given to her and then a cesarean section was performed due to acute fetal distress and oligoamnios. The mother was later confirmed as a case of epidemic influenza A (H1N1) and pulmonary tuberculosis.
