Health Behaviors and Attitudes Toward HIV Clinic Among Young Men who Have Sex with Men Living with HIV in Chiang Mai, Thailand: A Mixed Methods Study.

Today, many young men who have sex with men (YMSM) with a new HIV infection were diagnosed and successfully linked to HIV services. Studies on their health behaviors while living with HIV and their attitude toward the HIV clinic are scarce. We characterized common health behaviors of YMSM and assessed their perspective towards the existing HIV services. We collected data from a self-administered questionnaire and in-depth interviews (IDI) using a mixed-method cross-sectional study design. A hundred YMSM, aged 18-24, who attended the HIV clinic were enrolled. Their median age was 23 years (interquartile range, IQR 21-24). Eighty-four (84%) were gay men. Their common health behaviors included 15 (15%) being current smokers and 30 (30%) using alcohol regularly. Sixty-four (64%) reported > 95% antiretroviral treatment adherence, while 32 (32%) self-reported adherence at 80-95%. Fifty-three (53%) reported 100% condom use, while 30 (30%) reported using a condom in > 80% of their sexual activities. From the questionnaire respondents, individual characteristics of providers were the most critical factor affecting participants' willingness to attend HIV services. From the IDI, social disclosure of HIV status was their primary concern, with the presence of self- and anticipating HIV-related stigma issues. In summary, YMSM living with HIV who regularly attended the HIV clinic had a low frequency of health risk behaviors. Most did not socially disclose their serostatus but could manage their health. They were generally satisfied with patient-friendly services while calling to protect their confidentiality and privacy.

Assessment of U=U understanding, PrEP awareness, HIV risk behaviours and factors associated with low HIV knowledge among users of Hornet, an online dating application for LGBTQ, in Thailand.

BACKGROUND: Over 50% of HIV infections in Thailand annually occur among men who have sex with men (MSM) and transgender women who use online applications to meet their sexual partners. We conducted a cross-sectional study assessing undetectable=untransmittable (U=U) understanding, pre-exposure prophylaxis (PrEP) awareness, sexual behaviours and factors associated with HIV knowledge among users of Hornet in Thailand. METHODS: From November 2019 to January 2020, a survey was conducted using convenience sampling on Hornet in Thailand. HIV literacy was assessed via 22 questions, and multivariable linear regression was performed. RESULTS: 960 responses were assessed; median age was 34 years, the majority were MSM (80.4%), Thai (83.8%), had at least bachelor's degree (74.9%). Regarding the risk profiles, 39.1% reported inconsistent condom use, 15.0% used amphetamine-type stimulants, 56.9% had not taken PrEP in the last six months and 20.5% never had an HIV test. Only 22.8% thought that U=U was completely accurate. Lower HIV knowledge was associated with being from Africa (ß -8.13, 95% CI -14.39 to -1.87), age of 25 years or younger (ß -2.6, 95% CI -4.37 to -0.82), education less than bachelor's degree (ß -2.58, 95% CI -3.98 to -1.19), having more than one sexual partners (ß -2.41, 95% CI -4.13 to -0.69), paying three or more people to have intercourse (ß -2.5, 95% CI -4.26 to -0.74), not knowing one's HIV status (ß -3.56, 95% CI -5.45 to -1.68) and not answering about previous PrEP use (ß -4.11, 95% CI -7.86 to -0.36). Higher HIV knowledge was associated with being from Europe (ß 2.54, 95% CI 0.46 to 4.61), the Americas (ß 3.37, 95% CI 0.44 to 6.30) and previous PrEP use (ß 2.37, 95% CI 0.94 to 3.81). CONCLUSION: Among Hornet users in Thailand, the U=U message was unclear, and PrEP use was suboptimal. Large HIV knowledge gaps and high-risk behaviours were concerning. Educational campaigns in online spaces are needed to promote awareness and HIV prevention strategies.

Cardio-ankle vascular index of increased arterial wall stiffness is associated with neurocognitive impairment in well-controlled HIV.

OBJECTIVES: HIV-associated neurocognitive disorders (HAND) remain prevalent in people living with HIV (PLWH) despite widespread use of combined antiretroviral therapy (ART). Vascular disease contributes to the pathogenesis of HAND, but traditional vascular risk factors do not fully explain the relation between vascular disease and HAND. A more direct measure of vascular dysfunction is needed. This cross-sectional study tested whether the cardio-ankle vascular index (CAVI), a novel method to assess arterial stiffness, is associated with HAND among PLWH. METHODS: Participants included 75 non-diabetic adults with well-controlled HIV from an outpatient HIV clinic. We assessed the relation between CAVI and neurocognitive impairment (NCI). The latter was primarily characterized by the Frascati criteria and secondarily (post hoc) using the Global Deficit Score (GDS). Logistic regression models tested whether high CAVI (≥ 8) was independently associated with NCI when controlling for potential confounders. RESULTS: Participants (Mage  = 45.6 ± 8.3 years; 30.1% male) had few traditional cardiovascular disease (CVD) risk factors (hypertension, n = 7; dyslipidaemia, n = 34; body mass index ≥ 25 kg/m2 , n = 12; smoking history, n = 13; 2.2% mean 10-year risk of CVD or stroke). Twelve (16%) participants had high CAVI, which was independently associated with meeting Frascati criteria for NCI [n = 39, odds ratio (OR) = 7.6, p = 0.04], accounting for age, education, gender, income, CD4 nadir, recent CD4 and traditional CVD risk factors. High CAVI was also associated with NCI as reflected by higher GDS (OR = 17.4, p = 0.02). CONCLUSIONS: Cardio-ankle vascular index is a promising measure of vascular dysfunction that may be independently associated with NCI in relatively healthy PLWH. Larger studies should test the utility of CAVI in predicting NCI/decline in PLWH.

Pelvic and central nervous system tuberculosis complicated by a paradoxical response manifesting as a spinal tuberculoma: a case report.

BACKGROUND: The post-partum period is a risk factor for tuberculosis (TB), possibly including the period after miscarriage as illustrated here. This case demonstrates how non-specific symptoms can hide widely disseminated TB. CASE PRESENTATION: A healthy 26-year-old female with a history of recent miscarriage presented to the emergency department with non-specific symptoms of headache, abdominal pain, and sub-acute fevers. She had immigrated to the United States from the Marshall Islands 9 years prior. Two months prior to presentation she had a miscarriage at 18 weeks of pregnancy. On admission, transvaginal ultrasound revealed retained products of conception and abdominal computed tomography revealed findings consistent with tubo-ovarian abscesses and peritonitis. The obstetrics and gynecology service performed dilation and curettage (D&C) to remove retained products of conception. Acid-fast bacilli cultures from cerebrospinal fluid as well as specimens from D&C and intra-abdominal abscesses subsequently all grew TB. She was diagnosed with TB meningitis, peritonitis, endometritis, and tubo-ovarian abscesses. Her treatment course was complicated by a paradoxical response resulting in a spinal tuberculoma causing lower extremity weakness. The tuberculoma was treated with surgical decompression as well as continuation of treatment with anti-tubercular chemotherapy and steroids. CONCLUSION: Disseminated and extrapulmonary TB can present with non-specific symptoms. Recognition of risk factors for TB is critical for prompt diagnostic evaluation and treatment of this deadly disease. A paradoxical reaction needs to be taken into consideration when any new neurological symptoms occur during TB treatment.

Drug-drug interaction between itraconazole capsule and efavirenz in adults with HIV for talaromycosis treatment.

OBJECTIVES: To assess the pharmacokinetic of itraconazole capsule formulation and its active metabolite, hydroxyitraconazole, in adults with HIV diagnosed with talaromycosis in an endemic area, and to evaluate the drug-drug interaction between itraconazole/hydroxyitraconazole (ITC/OH-ITC) and efavirenz. METHODS: Open-label, single arm, sequential pharmacokinetic study. Eligible subjects were adults with HIV, ≥18 years old, with confirmed talaromycosis, initiating itraconazole capsule as part of standard talaromycosis treatment, in whom efavirenz-based ART was anticipated. Steady-state pharmacokinetic assessments (pre-dose and at 1, 3, 4, 5, 6, 8 and 12 h post dose) were performed for itraconazole/hydroxyitraconazole without and with efavirenz use. Mid-dose efavirenz concentrations were also assessed. Pharmacokinetics parameters were calculated using non-compartmental analysis. RESULTS: Ten subjects (70% male) were enrolled. At entry, median (range) age was 29.5 years (22-64), and CD4 cell count was 18.0 (1-39) cells/mm3. Geometric mean (95% CI) of itraconazole and hydroxyitraconazole AUC0-12 without efavirenz were 9097 (6761-12 239) and 11 705 (8586-15 959) ng·h/mL, respectively, with a median metabolic ratio of OH-ITC : ITC of 1.3 (95% CI 0.9-1.9). Intra-subject comparison revealed that both itraconazole and hydroxyitraconazole exposures were significantly reduced with concomitant efavirenz use, with the mean AUC0-12 of itraconazole and hydroxyitraconazole being 86% (71%-94%) and 84% (64%-97%) lower, respectively. With efavirenz, itraconazole trough concentrations were also below the recommended therapeutic level (0.5 µg/mL). All subjects had mid-dose efavirenz concentrations >1000 ng/mL. CONCLUSIONS: Concomitant administration of itraconazole capsule with efavirenz significantly reduced itraconazole and hydroxyitraconazole exposures. The clinical impact of this drug-drug interaction on talaromycosis treatment or prophylaxis in the era of potent ART needs further evaluation.

Psychometric utility of the international HIV dementia scale and Montreal Cognitive Assessment in HIV-associated asymptomatic neurocognitive impairment.

There is a growing need for brief screening measures for HIV Associated Neurocognitive Disorders (HAND). We compared two commonly used measures (the Montreal Cognitive Assessment [MoCA] and the International HIV Dementia Scale [IHDS]) in their ability to identify asymptomatic HAND (i.e., asymptomatic neurocognitive impairment [ANI]). Participants included 74 Thai PLWH: 38 met Frascati criteria for ANI and 36 were cognitively normal (CN). Participants completed Thai language versions of the MoCA (MoCA-T) and IHDS, and a validated neurocognitive battery. We examined between-group differences for MoCA-T and IHDS total scores, and scale subcomponents. We also conducted receiver operating characteristic (ROC) analyses to determine the ability of the MoCA-T and IHDS to discriminate between CN and ANI groups, and compared their area under the curve (AUC) values. Results revealed lower MoCA-T total score, as well as the Visuospatial/Executive and Delayed Recall subtask scores, in the ANI relative to CN group. Groups did not differ on the IHDS. For ROC analyses, the MoCA-T, but not the IHDS, significantly differentiated the ANI from CN group, and there was a significant difference in AUC values between the MoCA-T (AUC = .71) and IHDS (AUC = .56). Sensitivity and specificity statistics were poor for both screening measures. These data indicate while the MoCA-T functions better than the IHDS in detecting Thai PLWH with ANI, the mildest form of HAND, neither cognitive screener, showed strong utility. Our findings reflect the limited efficacy of common screening measures in detecting subtler cognitive deficits among Thai PLWH, and highlight the need for better screening tools.

Metabolic phenotype and adipose and liver features in a high-fat Western diet-induced mouse model of obesity-linked NAFLD.

nonalcoholic fatty liver disease (NAFLD), an obesity and insulin resistance associated clinical condition - ranges from simple steatosis to nonalcoholic steatohepatitis. To model the human condition, a high-fat Western diet that includes liquid sugar consumption has been used in mice. Even though liver pathophysiology has been well characterized in the model, little is known about the metabolic phenotype (e.g., energy expenditure, activity, or food intake). Furthermore, whether the consumption of liquid sugar exacerbates the development of glucose intolerance, insulin resistance, and adipose tissue dysfunction in the model is currently in question. In our study, a high-fat Western diet (HFWD) with liquid sugar [fructose and sucrose (F/S)] induced acute hyperphagia above that observed in HFWD-fed mice, yet without changes in energy expenditure. Liquid sugar (F/S) exacerbated HFWD-induced glucose intolerance and insulin resistance and impaired the storage capacity of epididymal white adipose tissue (eWAT). Hepatic TG, plasma alanine aminotransferase, and normalized liver weight were significantly increased only in HFWD+F/S-fed mice. HFWD+F/S also resulted in increased hepatic fibrosis and elevated collagen 1a2, collagen 3a1, and TGFß gene expression. Furthermore, HWFD+F/S-fed mice developed more profound eWAT inflammation characterized by adipocyte hypertrophy, macrophage infiltration, a dramatic increase in crown-like structures, and upregulated proinflammatory gene expression. An early hypoxia response in the eWAT led to reduced vascularization and increased fibrosis gene expression in the HFWD+F/S-fed mice. Our results demonstrate that sugary water consumption induces acute hyperphagia, limits adipose tissue expansion, and exacerbates glucose intolerance and insulin resistance, which are associated with NAFLD progression.

Herpes simplex and varicella zoster CNS infections: clinical presentations, treatments and outcomes.

OBJECTIVES: To describe the clinical manifestations, cerebrospinal fluid (CSF) characteristics, imaging studies and prognostic factors of adverse clinical outcomes (ACO) among adults with herpes simplex virus (HSV) or varicella zoster virus (VZV) CNS infections. METHODS: Retrospective review of adult patients with positive HSV or VZV polymerase chain reaction on CSF from an observational study of meningitis or encephalitis in Houston, TX (2004-2014), and New Orleans, LA (1999-2008). RESULTS: Ninety-eight adults patients were identified; 25 had encephalitis [20 (20.4 %) HSV, 5 (5.1 %) VZV], and 73 had meningitis [60 (61.1 %) HSV and 13 (13.3 %) VZV]. HSV and VZV had similar presentations except for nausea (P < 0.01) and rash (P < 0.001). The CSF profile did not differ between HSV and VZV infection. Abnormal neuroimaging findings were found in 11.6 % (10/86) brain CTs and 21.3 % (16/75) brain MRIs. The EEG was abnormal in 57.9 % (11/19). Sixteen patients (16.3 %) had an ACO (10 HSV encephalitis, 3 VZV encephalitis and 3 VZV meningitis). Intravenous acyclovir administered within 48 h was protective against an ACO [OR 0.19 (0.04-0.80), P = 0.02). However, on logistic regression only Charlson comorbidity score >1 and an encephalitis presentation were independently associated with an ACO. The treatment for HSV meningitis was variable, and all patients had a good clinical outcome. CONCLUSION: Alpha herpes CNS infections due to HSV and VZV infections have similar clinical and laboratory manifestations. ACO was observed more frequently in those patients with comorbidities and an encephalitis presentation.

Emerging Escherichia pathogen.

Escherichia hermannii was first identified as a new species in 1982. It has rarely been reported as a human pathogen. We report the first case of E. hermannii as the sole pathogen in a catheter-related bloodstream infection.

Presence of crystals is not an evidence of absence of infection.

Acute monoarthritis is one of the most common rheumatologic presentations. However, it is clinically difficult to distinguish between an inflamed joint due to crystal-induced arthritis and an inflamed joint due to septic arthritis. Arthrocentesis and synovial fluid analysis are used to differentiate between these 2 conditions. The presence of crystals and positive synovial fluid culture confirm the diagnosis of crystal-induced arthritis and septic arthritis, respectively. Although uncommon, these 2 arthritides can coexist, and presence of crystal does not exclude bacterial arthritis. We reported a case of 85-year-old woman whose synovial fluid contained crystals and was initially diagnosed with crystal-induced arthritis. However, her joint fluid culture subsequently grew Staphylococcus aureus, and she was treated with arthroscopic debridement and antibiotics.

Haemophilus influenzae serotype f as a rare cause of septic arthritis.

Non-type B Haemophilus influenzae emerges as a new pathogen in the post H. influenzae serotype b vaccine era. We describe a case of polyarticular septic arthritis caused by H. influenzae serotype f in an adult. The patient was successfully treated with surgical debridement and antibiotic. To the best of our knowledge, this is the fourth reported case of H. influenzae serotype f septic arthritis in adults.

Pulmonary blastomycosis: a new endemic area in New York state.

We describe three cases of pulmonary blastomycosis in patients from central New York State (NYS). Two of these cases occurred in 2012, and in patients who resided in the same county. Moreover, two of these cases manifested with acute respiratory distress syndrome and survived. Interestingly, one of the two received corticosteroids and was extubated within 1 week. To the best of our knowledge, these are the first cases of human blastomycosis to be reported from NYS and we propose that corticosteroids administration might reduce hospitalisation time and ventilator-associated complications, even though it is not currently recommended in standard treatment.

Long-acting preexposure prophylaxis in low- and middle-income countries: key considerations for implementation.

PURPOSE OF REVIEW: HIV preexposure prophylaxis (PrEP) is a key tool in ending the HIV epidemic. Long-acting cabotegravir (LA- CAB) phase II/III studies revealed promising efficacy in preventing HIV acquisition. Here, we discuss key considerations for implementing LA-CAB in low- and middle-income countries (LMIC). RECENT FINDINGS: PrEP roll out in LMIC is still far from ideal, and contextual factors within LMIC vary widely. Implementation science studies are urgently needed to optimize the implementation of LA-CAB in different settings, consider effective service delivery models, and ensure program sustainability. Preferences and concerns regarding LA-CAB among potential users are unknown but likely specific to local context. Demedicalized and simplified PrEP service delivery increases uptake, and ways to safely and effectively do the same for LA- CAB need to be explored. Although ideally LA-CAB should be an additional choice of HIV prevention method, its cost will be the major determinant in deciding its position as a first line choice or restricted second-line option. SUMMARY: LA-CAB has the potential to enhance PrEP uptake. However, several implementation challenges need to be explored and addressed to ensure it can be accessed and utilized in different settings by those who need it the most.

Seroepidemiological study of Japanese encephalitis virus in Chiang Mai: Immunity and susceptibility 28 years after introduction of a vaccination programme.

BACKGROUND: Thailand has introduced a nationwide vaccination against Japanese encephalitis virus (JEV) into National Immunization Programme since the 1990's. To improve the understanding of immunity and susceptibility of the population after 28 years of a vaccination programme, we conducted a JEV seroepidemiological study in a JEV-endemic area of Thailand. METHODS: An age-stratified, population-based, seroepidemiological study was conducted in Chiang Mai, Thailand-a northern Thai province where is an endemic area of Japanese encephalitis. Nine districts were chosen based on administrative definition: rural (n = 3); urban (n = 3); and peri-urban (n = 3). Within each district, eligible participants were randomly selected from 3 age groups: adolescents (10-20 years); adults (21-50 years); and older adults/elderly (≥51 years) by computer randomization. Plaque reduction neutralization tests (PRNT50 and PRNT90) were performed to measure neutralizing antibodies to JEV. To account for the cross-reactivity of JEV and other flaviviruses, JEV seroprotection was defined according to age, previous history of JEV vaccination, and PRNT50/PRNT90 levels of study participants. RESULTS: Overall, 279 adolescents, 297 adults, and 297 older adults/elderly were enrolled from nine districts. Age-stratified, protocol-defined, cluster-adjusted JEV seroprotection rates were 61% (95% CI: 48-73%), 43% (95% CI: 31-57%), and 52% (95% CI: 37-67%) for adolescents, adults, and older adults/elderly, respectively. Living in peri-urban districts, having a history of prior dengue virus infection, and previously receiving mouse brain-derived JEV vaccine were significantly associated with seroprotection to JEV in adolescents. Older age and male sex were associated with seroprotection for adults; and only male sex was the associated factor for older adults/elderly (P <0.05). CONCLUSIONS: Approximately half of population living in a JEV-endemic area demonstrated seroprotection to JEV. Ongoing nationwide surveillance on JEV seropepidemiology is an important strategy to understand the evolving population-level immunity to JEV, and to help formulating the appropriate recommendations on JE immunization.

Cardiovascular risks in Asian HIV-infected patients receiving boosted-protease inhibitor-based antiretroviral treatment.

INTRODUCTION: Increased risk of cardiovascular disease in HIV-infected patients was tought to be the cause of multiple mechanistic factors, which changing the HIV care landscape. Antiretroviral therapy (ART), especially protease inhibitors (PI), is one of common HIV treatments that may have some association with this. The mechanism of PI in comparison to other regimens, however, are not clearly understood. METHODOLOGY: Age-and gender-match HIV-infected patients treated with either boosted-PI-based regimen (boosted-PI group, N=30) or NNRTI-based ART (non-PI group, N = 30) were recruited for this cross-sectional study. Parameters determined cardiovascular risks, inflammation, endothelial function, and bone metabolic function were evaluated. RESULTS: Compared with non-PI, patients in the boosted-PI group had more evidence of dyslipidemia. No statistical difference in the prevalence of subclinical atherosclerosis was found between the two groups. Circulating levels of inflammatory markers, C-reactive protein (CRP) (5.4±9.1 vs. 14.9 ± 19.4 mg/L, p = 0.019) and lectin-liked oxidized lipoprotein receptor-1 (LOX-1) (387 ± 299 vs. 554 ± 324 pg/mL, p = 0.042) were lower in boosted-PI group. Contrastingly, Vascular adhesion molecules-1 (VCAM-1) (160.2 ± 80.0 vs. 147.8 ± 66.3 ng/mL, p = 0.010), and osteoprotegerin (OPG) (153.7 ± 57.1 vs. 126.4 ± 35.8, p = 0.031) were higher. After adjustment in the multivariate analysis, PI treatment is the only independent parameter associated with the changes of CRP, LOX-1, VCAM-1, and OPG. Subgroup analysis showed that ARV treatment effects differed among participant having dyslipidemia. CONCLUSIONS: The major mechanism in which PI-mediated was triggering atherogenesis could be through alteration of lipid metabolism and endothelial function, but no evidence of accelerated pro-inflammatory response was attested.

Degos-like lesions as a cutaneous manifestation of cytomegalovirus infection: A rare and serious complication in a patient with drug-induced hypersensitivity syndrome.

Cytomegalovirus causes a myriad of clinical features, potentially affecting any organ system, significantly increasing morbidity and even mortality. Vascular endothelial cell infection by cytomegalovirus has been implicated in the development of vasculopathy, possibly accounting for the clinical association between cytomegalovirus and vascular thrombosis. In contrast with visceral organ involvement, the cutaneous manifestations of cytomegalovirus are variable and rarely described. Malignant atrophic papulosis, commonly known as Degos disease, is an unusual small vessel arteriopathy with a pathognomonic clinical appearance of atrophic porcelain-white central papules surrounded by telangiectatic erythema. As with the arterial occlusive process, Degos disease may be idiopathic or secondary to autoimmune disorders or viral infection. All in all, cytomegalovirus-related Degos-like presentation has never been described. This report describes a case in which disseminated cytomegalovirus disease developed 4 weeks after the onset of drug-induced hypersensitivity syndrome with prominent Degos-like skin lesions. Our case highlights a rare example of Degos-like lesions occurring due to cytomegalovirus disease and emphasizes the importance of early recognition of the characteristic cutaneous eruption as a diagnostic clue leading to the prompt management of this life-threatening infection.

Adult-to-Adult Living Donor Liver Transplantation: Postoperative Outcomes and Quality of Life in Liver Donors: First Report in Thailand.

BACKGROUND: Deceased donor liver transplantation is a rare procedure in Northern Thailand because of cultural issues. Living donor liver transplantation (LDLT) can decrease waiting list mortality for the patients who have end-stage liver disease. In Thailand, our center is the only active adult-to-adult LDLT program. This study is the first report of outcomes and health-related quality of life in liver donors. OBJECTIVES: The aim of this study was to evaluate the postoperative outcomes and health related quality of life in living liver transplant donors at the Transplant Center in Thailand. MATERIALS AND METHODS: All patients undergoing liver resection for adult-to-adult LDLT at our center between March 2010 and July 2018 were evaluated in a cross-sectional study. The effect of donor demographics, operative details, postoperative complications (Clavien-Dindo classification), hospitalization, and health related quality of life was evaluated through health-related quality of life questionnaires (short-form survey, SF-36) RESULTS: A total of 14 donor patients were included in this study with an age range from 26 to 51 years (mean 39.86 years, standard deviation [SD] = 8.59 years). The patients were 71.43% female and 28.57% male. The majority of patients had primary and secondary education (57.14%) and were married (64.29%). After hepatectomy, there was no mortality in the evaluated donors. The Clavien-Dindo classification of postoperative complications were as follows: Grade I (none), Grade II (50%), Grade IIIa (7.14%), and Grade IIIb (7.14%). The serum levels of total protein and albumin were decreased on postoperative day 5. The hospital stays averaged 11.5 days (SD = 4.9 days) and ranged from 5 to 22 days. After considering each aspect of the donors' postoperative quality of life, the highest mean score was related to physical composite scores in physical roles with a mean of 96.42 (SD = 13.36) and physical function with a mean of 95.35 (SD = 13.36). Moreover, the mental composite scores in social function was the highest mean of 91.96 (SD = 12.60) and role emotion was a mean of 90.47 (SD = 27.51). CONCLUSIONS: Living donor hepatectomy was safe, with an acceptable morbidity, and recognized as a safe procedure with an excellent long-term health quality of life.

Nocardia beijingensis pericarditis presenting with cardiac tamponade: A case report.

We report the first case of Nocardia beijingensis pericarditis in a 32-year-old HIV-infected patient. He presented with cardiac tamponade after failing to respond to treatment for smear-negative pulmonary and pericardial tuberculosis (TB). The pericardial fluid was examined several times before it eventually revealed filamentous branching organisms in Gram and modified acid-fast bacilli stain. The culture grew Nocardia spp. and was identified by 16s rRNA sequencing as N. beijingensis. Eight previously reported cases of Nocardia pericarditis in HIV-infected patients were caused by Nocardia asteroides. All patients had low CD4 cell count (range: 17-239 cells/mm3) and 50% of patients were treated for tuberculous pericarditis prior to making the correct diagnosis of Nocardia pericarditis. This report revisits the issue of nocardiosis as a great TB mimicker. It should always be considered in the differential diagnosis among HIV-infected patients suspected of having pericardial TB that is failing treatment.
