APOL1 variant alleles associate with reduced risk for opportunistic infections in HIV infection.

Apolipoprotein L1 (APOL1), an innate immune factor against African trypanosoma brucei, inhibits HIV-1 in vitro. The impact of APOL1 G1-G2 variants on HIV-1-associated opportunistic infections (OIs) is unknown. Here, we report findings from a metaanalysis of four HIV/AIDS prospective cohorts (ALIVE, LSOCA, MACS, and WIHS) including 2066 African American participants. Using a global test combining all four cohorts, carriage of two APOL1 variant alleles is associated with a 50% reduction in odds of OI (combined OR 0.50, 95% CI 0.33-0.76). Subgroup analysis of OI etiological categories (viral, parasitic, fungal and Mycobacterial) suggests the possibility of specific protection from fungal infections (OR 0.54. 95% CI 0.32-0.93; PBonferroni corrected = 0.08). We observe an association of APOL1 variant alleles with host protection against OI in HIV-positive individuals. The study suggests a broader role of APOL1 variant alleles in innate immunity in vivo.

Subcutaneous nodules of cysticercosis as a sign of asymptomatic neurocysticercosis in an HIV positive patient

Abstract Cysticercosis is caused by the hematogenous dissemination of the larval form (cysticercus) of Taenia solium. It can affect any organ or tissue in the body but commonly affects the subcutaneous tissue, central nervous system, eyes, and skeletal muscle. Skin lesions can assist as a marker in the diagnosis of asymptomatic neurocysticercosis in endemic areas. A 49-year-old HIV positive man presented with multiple cutaneous nodules confirmed as cysticercomas which led to the diagnosis of asymptomatic neurocysticercosis. He was successfully treated with albendazole and steroids at recommended doses with no adverse effects.

The role of agency in the implementation of Isoniazid Preventive Therapy (IPT): Lessons from oMakoti in uMgungundlovu District, South Africa.

INTRODUCTION: In response to revisions in global and national policy in 2011, six-month isoniazid preventive therapy (IPT) became freely available as a preventive measure for people living with HIV in the uMgungundlovu District of KwaZulu-Natal province, South Africa. Given a difference in uptake and completion by sex, we sought to explore the reasons why Zulu women were more likely to accept and complete IPT compared to men in an effort to inform future implementation. METHODS: Utilising a community-based participatory research approach and ethnographic methods, we undertook 17 individual and group interviews, and met regularly with grassroots community advisory teams in three Zulu communities located in uMgungundlovu District between March 2012-December 2016. FINDINGS & DISCUSSION: Three categories described women's willingness to initiate IPT: women are caregivers, women are obedient, and appearance is important. The findings suggest that the success of IPT implementation amongst clinic-utilising women of uMgungundlovu is related to the cultural gender norms of uMakoti, isiZulu for "the bride" or "the wife." We invoke the cultural concept of inhlonipho, meaning "to show respect," to discuss how the cultural values of uMakoti may conflict with biomedical expectations of adherence. Such conflict can result in misinterpretations by healthcare providers or patients, and lead some patients to fear the repercussions of asking questions or contemplating discontinuation with the provider, preferring instead to appear obedient. We propose a shift in emphasis from adherence-focussed strategies, characteristic of the current biomedical approach, to practices that promote patient agency in an effort to offer IPT more appropriately. IMPLICATIONS: Building on existing tools, namely the harm reduction model and the use of mini-ethnography, we provide guidance on how to support women to participate as agents in the decision to initiate or continue IPT, decisions which may also impact the health and choices of the family.

Immune reconstitution inflammatory syndrome versus non-immune reconstitution inflammatory syndrome lymphoma in HIV patients on antiretroviral therapy.

Little is known about differences between immune reconstitution inflammatory syndrome (IRIS) and non-IRIS lymphoma in HIV patients on antiretroviral therapy (ART). The aim of this study was to describe the characteristics of IRIS and non-IRIS lymphoma in Korean HIV-positive patients on ART compared with lymphoma in those off ART. Of 1490 patients, 41 (3%) had lymphoma. Of these, 27 cases (66%) were classified as lymphoma off ART, eight as IRIS lymphoma, and six as non-IRIS lymphoma on ART. Hodgkin lymphoma was significantly more common among patients with non-IRIS lymphoma on ART than among those with lymphoma off ART (P = 0.005), whereas there was no Hodgkin lymphoma among IRIS lymphoma. Stage IV lymphoma was significantly rarer in non-IRIS lymphoma on ART than in lymphoma off ART (P = 0.007). Non-IRIS lymphoma on ART tends to have a better survival rate than lymphoma off ART (Kaplan-Meier survival analysis, P = 0.167), while IRIS lymphoma exhibited a survival rate similar to lymphoma off ART (P = 0.618). In Korean HIV-positive patients, there were significantly more cases of Hodgkin lymphoma of a less advanced stage in non-IRIS lymphoma on ART than in lymphoma off ART, in contrast to IRIS lymphoma.

Características microbiológicas y epidemiológicas de la infección del torrente sanguíneo en pacientes HIV/SIDA / Microbiological and epidemiological characteristics of bloodstream infection in HIV / AIDS patients

INTRODUCCIÓN: los individuos seropositivos al virus de la inmunodeficiencia humana, tienen un alto riesgo para desarrollar una infección del torrente sanguíneo. OBJETIVO: identificar los agentes etiológicos y los factores de riesgo asociados a esta entidad. MÉTODOS: se realizó un estudio observacional prospectivo desde febrero hasta diciembre de 2012. El universo estuvo conformado por 118 pacientes. La identificación microbiana se realizó mediante el sistema automatizado VITEK 2 Compact. Para determinar la asociación entre las variables se calculó la razón de prevalencia. RESULTADOS: Predominaron los pacientes del sexo masculino, con edades entre 41-50 años, severamente inmunodeprimido y con terapia antirretroviral. La mayoría de los aislamientos correspondieron a las enterobacterias, con predominio de Klebsiella pneumoniae. Staphylococcus aureus constituyó la principal bacteria grampositiva aislada. Las variables que se asociaron con el desarrollo de enfermedad invasiva fueron: el empleo de catéter venoso central, el tratamiento con hemodiálisis y la estadía hospitalaria mayor de 7 días. CONCLUSIONES: se ratifica a las bacterias gramnegativas como importantes agentes causales de bacteriemia en los pacientes VIH/sida. Los procederes invasivos constituyen los principales factores de riesgo para el desarrollo de bacteriemia en pacientes VIH positivos.

INTRODUCTION: human immunodeficiency virus seropositive individuals are at high risk for developing a bloodstream infection. OBJECTIVE: to identify the etiologic agents and risk factors associated with this entity. METHODS: a prospective observational study was conducted from February to December 2012. The study group consisted of 118 patients. Microbial identification was performed by the VITEK 2 Compact automated system. Variables were calculated to determine the association between the prevalence ratio. RESULTS: predominance of male patients, aged 41-50 years, severely immunecompromised and undergoing antiretroviral therapy was observed. Enterobacter Staphylococcus aureus was the main isolated Gram-positive bacterium. CONCLUSIONS: gram-negative bacteria are ratified as important causative agents of bacteremia in HIV / AIDS patients. The invasive procedures are major risk factors for the development of bacteremia in HIV positive patients

Outcomes of cytomegalovirus retinitis-related retinal detachment surgery in acquired immunodeficiency syndrome patients in an Asian population.

BACKGROUND: This study reports the surgical outcomes of acquired immunodeficiency syndrome (AIDS) patients with Cytomegalovirus retinitis (CMVR) -related retinal detachments(RD) in an Asian population. METHODS: Review of CMVR characteristics, surgical outcomes and complications in 19 eyes with CMVR-related RD that underwent surgery from January 2000 to June 2011. RESULTS: CMVR was inactive in 73.7% of the eyes at time of surgery. Anatomical success was achieved in 14 eyes. Seven eyes (36.8%) had improvement of two or more lines in visual acuity (VA) and 8 eyes (42.1%) maintained VA. Thirteen eyes presented with worse than 6/120 vision, with 30.8% of them achieving ambulatory vision or better. Five eyes had re-detachments. Median durations from CMVR and immune recovery uveitis (IRU) diagnoses to RD were 2.7 and 1.0 months respectively. CONCLUSIONS: Surgery for CMVR-related RD is associated with good anatomical outcomes with most eyes maintaining or having improved vision. CMVR lesion size of <50% retinal area is associated with better outcomes. Eyes with CMVR and IRU require close monitoring for RD.

African Kaposi's sarcoma in the light of global AIDS: antiblackness and viral visibility.

Drawing on the theoretical frameworks of antiblackness and intersectionality and the concept of viral visibility, this essay attends to the considerable archive of research about endemic Kaposi's sarcoma (KS) in sub-Saharan Africa accrued during the mid-20th century. This body of data was inexplicably overlooked in Western research into KS during the first decade of the AIDS epidemic, during which period European and Mediterranean KS cases were most often cited as precedents despite the volume of African data available. This paper returns to the research on KS conducted in Africa during the colonial and postcolonial period to consider visibility, racial erasure, and discourses of global epidemiology, suggesting that the dynamics of medical research on HIV/AIDS have proceeded according to a tacit paradigm of antiblackness manifest in multiple exclusions of Africa from global health agendas--most recently the exclusion of the region from antiretroviral (ARV) drug therapy during the first decades of the treatment's availability. During that decade KS all but disappeared among people with access to ARV therapy while KS became even more prevalent in sub-Saharan Africa, escalating along with HIV.

The impact of human immunodeficiency virus-related diseases on pigmented skin types.

Infection with human immunodeficiency virus (HIV) remains a significant problem globally. Early diagnosis and treatment with antiretroviral drugs has considerably improved health outcomes and decreased disease-related morbidity. HIV infection is associated with a wide range of skin disorders enabling dermatologists to diagnose HIV as well as associated opportunistic infections early in the course of disease. Despite concerted efforts by international health organizations to limit disease incidence, the prevalence of HIV infection remains high and is highest in sub-Saharan Africa. The diagnosis of HIV-related skin diseases is challenging as immunosuppression often results in atypical disease presentation. In addition, the clinical presentation will vary in pigmented skin types. The aim of this article is to describe disease variation in pigmented skin types.

Assessing the influence of health literacy on HIV-positive women's cervical cancer prevention knowledge and behaviors.

Women living with HIV (WLH) bear a disproportionate burden of cervical cancer and may face challenges understanding health information. The purpose of this study was to assess the influence of health literacy on WLH cervical cancer screening knowledge and behaviors. WLH were recruited from clinic- and community-based settings in the southeastern USA. The majority of women completing a questionnaire assessing factors related to cervical cancer were African American (90 %). About 38 % of women reported low health literacy. Compared to women with high health literacy, these women were more likely to report having had ≥ 2 Pap tests during the year after HIV diagnosis (p=0.02), and less likely to have had a Pap test <1 year previously (p=0.05). There was no difference in cervical cancer or human papillomavirus knowledge among those with low versus high health literacy. Results revealed mixed finding on the influence of health literacy on screening knowledge and behaviors.

Inequalities in HIV disease management and progression in migrants from Latin America and sub-Saharan Africa living in Spain.

OBJECTIVES: The objective of the study was to analyse key HIV-related outcomes in migrants originating from Latin America and the Spanish-speaking Caribbean (LAC) or sub-Saharan Africa (SSA) living in Spain compared with native Spaniards (NSP). METHODS: The Cohort of the Spanish AIDS Research Network (CoRIS) is an open, prospective, multicentre cohort of antiretroviral-naïve patients representing 13 of the 17 Spanish regions. The study period was 2004-2010. Multivariate logistic or Fine and Gray regression models were fitted as appropriate to estimate the adjusted effect of region of origin on the different outcomes. RESULTS: Of the 6811 subjects in CoRIS, 6278 were NSP (74.2%), LAC (19.4%) or SSA (6.4%). For these patients, the follow-up time was 15870 person-years. Compared with NSP, SSA and LAC under 35 years of age had a higher risk of delayed diagnosis [odds ratio (OR) 2.0 (95% confidence interval (CI) 1.5-2.8) and OR 1.7 (95% CI 1.4-2.1), respectively], as did LAC aged 35-50 years [OR 1.3 (95% CI 1.0-1.6)]. There were no major differences in time to antiretroviral therapy (ART) requirement or initiation. SSA exhibited a poorer immunological and virological response [hazard ratio (HR) [corrected] 0.8 (95% CI 0.7-1.0) and HR [corrected] 0.7 (95% CI 0.6-0.9), respectively], while no difference was found for LAC. SSA and LAC showed an increased risk of AIDS for ages between 35 and 50 years [HR 2.0 (95% CI 1.1-3.7) and HR [corrected] 1.6 (95% CI 1.1-2.4), respectively], which was attributable to a higher incidence of tuberculosis. However, no statistically significant differences were observed in mortality. CONCLUSIONS: Migrants experience a disproportionate diagnostic delay, but no meaningful inequalities were identified regarding initiation of treatment after diagnosis. A poorer virological and immunological response was observed in SSA. Migrants had an increased risk of AIDS, which was mainly attributable to tuberculosis.

The state of disparities in opportunistic infection prophylaxis for blacks with HIV/AIDS.

OBJECTIVES: The purpose of this review is to identify and analyze published studies that have evaluated disparities for opportunistic infection (OI) prophylaxis between blacks and whites with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) in the United States. METHODS: The authors conducted a web-based search of MEDLINE (1950-2009) to identify original research articles evaluating the use of OI prophylaxis between blacks and whites with HIV/AIDS. The search was conducted utilizing the following MeSH headings and search terms alone and in combination: HIV, AIDS, Black, race, ethnicity, disparities, differences, access, opportunistic infection, and prophylaxis. The search was then expanded to include any relevant articles from the referenced citations of the articles that were retrieved from the initial search strategy. Of the 29 articles retrieved from the literature search, 19 articles were excluded. RESULTS: Ten publications met inclusion criteria, collectively published between 1991 and 2005. The collective time periods of these studies spanned from 1987 to 2001. Four studies identified a race-based disparity in that blacks were less likely than whites to use OI prophylaxis, whereas 5 studies failed to identify such a relationship between race and OI prophylaxis. One study identified disparities for Mycobacterium avium complex prophylaxis, but not for Pneumocystis jiroveci pneumonia prophylaxis. CONCLUSIONS: The evidence regarding race-based disparities in OI prophylaxis is inconclusive. Additional research is warranted to explore potential race-based disparities in OI prophylaxis.

[Assessment of the impact of the new health legislation on illegal immigrants in Spain: the case of human immunodeficiency virus infection]. / Evaluación del impacto del nuevo marco legal sanitario sobre los inmigrantes en situación irregular en España: el caso de la infección por el virus de la inmunodeficiencia humana.

The immigrant population in Spain, whether legal or not, has been entitled to healthcare under the same conditions as the Spanish population since the year 2000. The entry into vigour of the Royal Decree-Law 12/2012 of 20 April has significantly restricted this right, so that unauthorized or non-resident foreigners may now only receive emergency care, if they are under 18 or pregnant women. Out of an estimated 459,909 illegal immigrants in our country, 2,700 to 4,600 are probably infected with HIV; 1,800 to 3,220 know that they are infected, and 80% of the latter could receive antiretroviral treatment. The Royal Decree-Law is likely to cause many undesirable consequences in this population infected with HIV: increasing mortality, promoting the emergence of opportunistic diseases, increasing hospital admissions, increasing infections in the population (by HIV and other pathogens), or contributing to mother to child transmission of HIV. The expected increase in morbidity and mortality will be a greater cost in patient care, a cost which will be significantly higher in the more immunosuppressed patients. Therefore, the enforcement of the Royal Decree-Law will be much less cost-effective in the short term than was expected, and will negatively affect our country's public health, especially for those patients infected with HIV who will not be covered, thus increasing healthcare medium to long term costs, and moving away from the international health goals that were established.

Differences in the use of health resources by Spanish and immigrant HIV-infected patients.

BACKGROUND: HIV-immigrant use of health services and related cost has hardly been analysed. We compared resource utilisation patterns and direct health care costs between Spanish and immigrant HIV-infected patients. METHODS: All HIV-infected adult patients treated during the years 2003-2005 (372 patients) in this hospital were included. We evaluated the number of out-patient, Emergency Room (ER) and Day-care Unit visits, and number and length of admissions. Direct costs were analysed. We compared all variables between immigrant and Spanish patients. RESULTS: Immigrants represented 12% (n=43) of the cohort. There were no differences in the number of out-patient, ER, and day-care hospital visits per patient between both groups. The number of hospital admissions per patient for any cause was higher in immigrant than in Spanish patients, 1.3 (4.4) versus 0.9 (2.7), P=.034. A high proportion of visits, both for the immigrant (45.1%) and Spanish patients (43.0%), took place in services other than Infectious Diseases. Mean unitary cost per patient per admission, out-patient visits and ER visits were similar between groups. Pharmacy costs per year was higher in Spanish patients than in immigrants (7351.8 versus 7153.9 euros [year 2005], P=.012). There were no differences in the total cost per patient per year between both groups. The global distribution of cost was very similar between both groups; almost 75% of the total cost was attributed to pharmacy in both groups. CONCLUSIONS: There are no significant differences in health resource utilisation and associated costs between immigrant and Spanish HIV patients.

[Clinico-epidemiological characteristics of HIV-positive immigrants: study of 371 cases]. / Características clínico-epidemiológicas de los pacientes inmigrantes con infección por el VIH: estudio de 371 casos.

INTRODUCTION: The number of HIV-positive immigrants have increased in Spain in the last few years, and now represent a significant proportion of the epidemic. Our objective is to describe the clinico-epidemiological characteristics of HIV-positive immigrants seen in a specialist unit in Madrid. MATERIAL AND METHODS: Retrospective study. Every patient born in a country other than Spain and attended an HIV Unit in Madrid between 1992 and 2009 was included. RESULTS: Of the 371 patients included, 53.1% were Latin Americans, 24.5% Sub-Saharan Africans, and 22.4% others), and 60% were males. Immigrants represented 0.3% of new patients in 1992 and rose to 49.2% in 2009. The principal reason for HIV testing had been pregnancy/delivery among women (32.7%) and having a category-B disease among men (17.4%). Sexual transmission accounted for 92% of patients. Tuberculosis was the principal AIDS-diagnosing illness. Respectively 90%, 7.7%, 60%, 26.7%, 96% and 95% of patients had an IgG for HAV, HCV, Toxoplasma, Treponema, CMV and VZV. VHB-Ags+: 5.4%; PPD+: 17%. At least one syphilis episode was recorded in 62% of the men who have sex with men (MSM). Prevalence of HLA-B5701 was 6%, 0.9% and 3.8% in Caucasians, Amerindians and Afro-Americans, respectively. CONCLUSIONS: Immigrants represent a significant proportion of new HIV-positive patients. It is a very heterogeneous group according to their clinical and epidemiological characteristics.

Late entry to HIV care among Latinos compared with non-Latinos in a southeastern US cohort.

BACKGROUND: Late diagnosis of human immunodeficiency virus (HIV) infection remains common despite advances in therapy and prognosis. The southeastern United States is a rapidly growing Latino settlement area where ethnic disparities may contribute to late presentation to care. METHODS: We assessed demographic and clinical factors between racial/ethnic groups at the time of HIV care initiation in the University of North Carolina Center for AIDS Research Clinical Cohort. We identified independent predictors of late presentation, defined as a CD4(+) T lymphocyte (CD4) count <350 cells/mm(3) or an AIDS-defining event (ADE), using log-linear binomial regression. RESULTS: During the period 1999-2009, 853 patients initiated HIV care, of whom 11% were Latino, 28% were white, and 61% were black. Median initial CD4 counts were lower for Latino patients (186 cells/mm(3)) than white patients (292 cells/mm(3); P = .006) and black patients (302 cells/mm(3); P = .02). Latino persons were more likely to be late presenters than white or black persons (76% vs 58%; P < .001) and accounted for 86%, 75%, and 50% of all presenting cases of active tuberculosis, histoplasmosis, and toxoplasmosis, respectively. Latino ethnicity, older age, male sex, and earlier entry year were independently associated with late presentation (P < .05 for all). In multivariable analyses, Latino persons were 1.29 times more likely to present to care late than white or black persons (95% confidence interval, 1.15-1.45). CONCLUSIONS: Latinos are more likely to initiate HIV care later in the course of illness than are black and white persons and account for a majority of several ADEs. Strategies to improve earlier HIV testing among Latinos in new settlement areas are needed.

Prevalence of Strongyloides stercoralis infection among HIV-positive immigrants attending two Italian hospitals, from 2000 to 2009.

In patients with Strongyloides stercoralis infection, a dysregulation of host immunity can lead to hyperinfection syndrome (HS) and disseminated strongyloidiasis (DS), characterized by high fatality rate. HS has been reported in HIV-positive patients following use of corticosteroids or during immune reconstitution inflammatory syndrome (IRIS). A retrospective study was conducted to estimate the prevalence of S. stercoralis infection among HIV-positive immigrants, attending two Italian hospitals. From January 2000 to August 2009, 138 HIV-positive immigrants were systematically screened for strongyloidiasis, as a part of their routine care, with an indirect immunofluorescent antibody test (IFAT) developed at the Centre for Tropical Diseases, Sacro Cuore Hospital of Negrar, Verona. The majority were also submitted to stool examination. Fifteen (11%) resulted infected by S. stercoralis, of whom four (27%) had a negative serology (diagnosis made with stool examination). A higher eosinophil count (0·94 versus 0·24×10(9)/l, P<0·01) and more frequent gastrointestinal and cutaneous symptoms (odds ratio: 4·8 and 5·8, respectively) were found in patients with strongyloidiasis compared with controls. The IFAT is more sensitive than direct parasitological methods. The proportion of false negative results was higher than expected based on the theoretical test sensitivity. Considering the high prevalence detected and the apparent, lower sensitivity of serology, we propose a systematic screening for Strongyloides infection, with both serology and stool culture, for all HIV-positive immigrants coming from endemic areas.

HIV-associated histoplasmosis in a nonendemic area of the United States during the HAART era: role of migration from endemic areas and lack of antiretroviral therapy.

Histoplasmosis is known to be an AIDS-associated infection, with scattered areas of endemicity throughout the world. Although the Atlanta, GA, metropolitan area is not a highly endemic area, a significant number of cases have been noted at our institution in recent years. Cases of histoplasmosis over a 4-year period were reviewed. All 27 patients (100%) were HIV infected. Thirty percent of patients with histoplasmosis were from Latin American countries. Patients from Latin America were younger than patients from the United States, tended to be more likely to have proven disease, and were exclusively male. Patients with proven disease had significantly higher urine histoplasma antigen levels, lower platelets counts, and lower neutrophil counts than patients with probable disease. The majority of patients survived after treatment with antifungals and initiation of antiretroviral therapy. Histoplasmosis is thus an important consideration in the workup of patients with advanced HIV in nonendemic areas of the United States.

High HIV-TB co-infection rates in marginalized populations: evidence from Alberta in support of screening TB patients for HIV.

Heretofore we have not seen strong evidence of synergy between HIV and tuberculosis (TB) in Canada. This may simply reflect a lack of concurrent surveillance for the two diseases. To date, the goal of universal HIV testing of TB patients (> 80% tested) in Canada has not been achieved, despite the existence of two national advisories recommending universal HIV testing of TB patients. In response to these advisories, we recently undertook to demonstrate the feasibility of using an 'opt-out' approach to achieve universal HIV testing of TB patients in Alberta--see the Canadian Journal of Public Health 2009;100(2):116-20. In the present commentary, we add two more years of data (2007-2008) to our earlier report and demonstrate for the first time that HIV co-infection is significantly greater in middle-aged (35-64 years) compared to young adult (15-34 years) TB patients and in Aboriginal and sub-Saharan African, compared to Canadian-born non-Aboriginal and foreign-born 'other' TB patients. Our findings underscore the need for universal concurrent testing as well as greater interaction between TB and HIV programs.

Lymph node tuberculosis in patients from regions with varying burdens of tuberculosis and human immunodeficiency virus (HIV) infection.

BACKGROUND: Few large cohorts of patients with lymph node tuberculosis (LNTB) have been reported in developed countries. OBJECTIVE: To describe the epidemiological and clinical characteristics of LNTB in patients living in France but born and raised in geographic areas with varying burdens of tuberculosis and human immunodeficiency virus (HIV) infection. DESIGN: A retrospective study of all patients with bacteriologically-proven LNTB assessed in a French hospital from March 1996 through April 2005. RESULTS: The analysis included 92 patients. HIV coinfected patients had a higher risk than those without HIV of presenting with disseminated TB and systemic symptoms and of hospitalization. Lymph node diagnostic procedures had a high yield when samples were cultured. About 25% of patients had an abnormal chest radiograph, and most of them were positive for acid-fast bacilli on sputum smears or for Mycobacterium tuberculosis culture. Treatment was generally prescribed for a longer duration than that recommended by international guidelines. One quarter of the patients developed a paradoxical reaction. A high proportion of our patients were classified as nonadherent and 20% defaulted or were lost to follow-up. CONCLUSION: Most of the differences in the clinical presentation among patients from various geographic areas were driven by the epidemiology of TB and HIV in the countries of origin. LNTB is frequently a clinical sign of disseminated disease, and culture for M. tuberculosis from LN or other sites is crucial for diagnosis. Adopting the strategy of Directly Observed Treatment, Short course (DOTS) might reduce the rates of nonadherence and default.
