ABSTRACT The influence of host factors (tobacco use, dentition, bleeding gums, oral rinsing, nasal medications, and time since the last meal) on immunoglobulin G (IgG) concentration in oral fluids (OF) was determined by univariate and multivariate analysis. Significant differences in IgG concentration were found to be associated with human immunodeficiency virus (HIV) status (HIV antibody positive, +16.60 μg/ml, P = 0.0001), sex (female, +1.23 μg/ml, P = 0.004), dentition (+2.83 μg/ml, edentulous versus dentulous, P = 0.0001), bleeding gums (+6.35 μg/ml, P = 0.0001), and time since the last meal (+3.55 μg/ml, >6 h, P = 0.0001). These factors could impact diagnostic methods that rely on the immunoglobulin concentration in OF specimens.

ABSTRACT Serological assays are valuable tools for studies of the epidemiology of human papillomaviruses (HPVs). The efficacy of a less invasive oral-fluid assay for detection of HPV antibodies was examined. Matched serum, saliva, and oral mucosal transudate (OMT) specimens collected from 150 human immunodeficiency virus-seropositive patients were tested for immunoglobulin G antibodies against HPV-6 and HPV-11 combined (HPV-6/11) and HPV-16 capsids. Antibodies to HPV were detected in both types of oral specimens. Seroprevalence rates were 55% for HPV-6/11 and 37% for HPV-16, whereas oral prevalence rates were significantly lower (for HPV-6/11 in saliva, 31%, and in OMT, 19%; for HPV-16 in saliva, 19%, and in OMT, 17%). HPV antibody detection in OMT more accurately reflected the presence of antibodies in serum than did HPV antibody detection in saliva. More stringent saliva assay cutpoints yielded stronger associations between oropositivity and seropositivity; less stringent OMT cutpoints yielded stronger associations between oropositivity and seropositivity. Although HPV antibodies were detected in oral fluids, further optimization of the assay is necessary before oral-fluid testing can be implemented as a reliable alternative to serum testing for HPV.

AbstractIntroductionHuman immunodeficiency virus and protein energy malnutrition are still prevalent in Nigeria and the occurrence of the two conditions together confers a poor prognosis. The aim of this study was to determine the current categories of malnutrition amongst under 5 children in Lagos, document their HIV status and determine any peculiarities in the clinical features, haematological and some biochemical profile in these children.MethodsThe study was a prospective crossectional study conducted at the Paediatric department of the Lagos University Teaching Hospital and the Massey Street Children’s Hospital over a 6 month period. All the subjects had anthropometry, HIV testing, full blood count and serum proteins done. The factors associated with HIV status were determined with the logistic regression analysis.ResultsTwo hundred and fourteen (214) malnourished children ≤5 years were recruited into the study and 25(11.7%) were HIV positive. One hundred and five (49.1%) of the participants had moderate malnutrition while 25.2% had severe forms of malnutrition. Fever, cough and diarrhea were the commonest symptoms. Severe wasting, oral thrush, dermatoses and splenomegaly were seen more commonly in the HIV positive subjects. The haematological indices were comparable in the two groups, however, the total protein was significantly higher in the HIV positive subjects compared to the negative group (p=0.042). Multivariate analysis showed that the total protein (p=0.001) and platelet count (p=0.016) could significantly predict the occurrence of HIV in the malnourished childrenConclusionThe presence of severe wasting, oral thrush, diarrhea, splenomegaly, thrombocytopenia and high total proteins in malnourished children should heighten the suspicion of possible underlying associated HIV infection. This study reinforces the recommendation by the World Health Organisation (WHO) that all malnourished children should have mandatory HIV screening.

The Difference

Background: Karnataka is one of the six high human immunodeficiency virus (HIV) prevalent states in India. We estimated prevalence among primigravida attending antenatal clinics in Karnataka, assuming this as a proxy for HIV incidence level in the general population.Methods: We tried estimating prevalence among primigravida using cross sectional samples. Data was collected in structured data extraction sheet for the month of September 2011, from all Integrated and Counselling tested Centres (ICTCs) of Karnataka. All the pregnant women were tested as per national protocol. We analysed the basic demographic data, geographical distribution including HIV status of spouse of primigravida.Results: In September 2011, 87580, pregnant women were tested and 238 (0.26%) were found HIV positive of which, 95 (40%) were primigravida. Prevalence among primigravida, was 0.3%. The prevalence among primigravida was highest in Bagalkot (1.6%) district. In Yadgir, Kodagu and Udupi the prevalence was zero. The high prevalent blocks were Jamakhandi, Mudhol, Gokak, Hospet and Muddebihal. 73.7% spouse of positive primigravida were tested for HIV and among those tested, 87.1% were found HIV positive.Conclusions: There is striking difference in the prevalence of HIV among primigravida in different districts of Karnataka probably indicates the difference in effectiveness of preventive interventions in these districts and within blocks. The preventive programs should be reached out to the labourer's and farmers in the general population to prevent the new infections in the general population.

BACKGROUND: The morbidity and mortality rates due to human immunodeficiency virus (HIV) infection are still high despite various and advanced efforts in the management given for HIV/AIDS patients. AIM: This study proposed that clinical signs and laboratory parameters could be expected to predict the patient’s mortality. METHODS: This retrospective study was done by collecting 408 medical records of adult HIV/AIDS inpatients at a tertiary hospital in Surabaya from January 1, 2017, to December 31, 2019. Bivariate analysis using Chi-square test was carried out on nine variables, which were Glasgow Coma Scale (GCS) <15, hypotension, PaO2/FiO2 <400 mmHg, elevated liver enzymes, hemoglobin levels <10 mg/dl, platelet count <150,000/mm3, eGFR <60 ml/min/1.73 m2, albumin levels <3.5 mg/dl, and body mass index (BMI) <18.5 kg/m2. Variables which met the criteria would be included in the multivariate analysis using logistic regression. RESULTS: Based on bivariate analysis, mortality was found to be significantly associated with GCS <15, hypotension, PaO2/FiO2, elevated liver enzymes, platelet count <100,000 mm3, eGFR <60 ml/1.73kg/m2, albumin levels <3.5 mgdl, and BMI <18.5 kg/m2. However, based on multivariate analysis, there were five variables which were found to be able to independently predict the patients’ mortality, those were GCS <15 (OR 11.625), hypotension (OR 6.062), PaO2/FiO2< 400 mmHg (OR 7.794), eGFR <60 ml/min/1.73 m2 (OR 2.646), and albumin levels <3.5 mg/dl (OR 4.091). CONCLUSION: GCS <15, hypotension, PaO2/FiO2 <400 mmHg, eGFR <60 ml/1.73g/m2, and albumin levels <3.5 mg/dl were found as the independent risk factors which could predict the hospitalized HIV/AIDS patients’ mortality.

Lower Extremity Revascularization

The development of highly active antiretroviral therapy (HAART) has significantly improved the life expectancy of patients with human immunodeficiency virus (HIV), but has led to the rise of chronic conditions including peripheral artery disease (PAD). However, trends and outcomes among patients with HIV undergoing lower extremity revascularization are poorly characterized. The aim of this study was to investigate the trends and perioperative outcomes of lower extremity revascularization among patients with HIV and PAD in a national database. The National Inpatient Sample (NIS) was reviewed between 2003 and 2014. All hospital admissions with a diagnosis of PAD undergoing lower extremity revascularization were stratified based on HIV status. Outcomes were assessed using propensity score matching and multivariable regression. Among all patients undergoing lower extremity revascularization for PAD, there was a significant increase in the proportion of patients with HIV from 0.21% in 2003 to 0.52% in 2014 ( p < 0.01). Patients with HIV were more likely to be younger, male, and have fewer comorbidities, including coronary artery disease and diabetes, at the time of intervention compared to patients without HIV. With propensity score matching and multivariable regression, HIV status was associated with increased total hospital costs, but not length of stay, major amputation, or mortality. Patients with HIV with PAD who undergo revascularization are younger with fewer comorbidities, but have increased hospital costs compared to those without HIV. Lower extremity revascularization for PAD is safe for patients with HIV without increased risk of in-hospital major amputation or mortality, and continues to increase each year.

Abstract Background Increased risk of asthma and chronic obstructive pulmonary disease has been reported in people living with human immunodeficiency virus (PLWH). Fraction of exhaled nitric oxide (FeNO) is a marker of eosinophilic airway inflammation. We assessed FeNO levels in PLWH and matched uninfected controls and investigated whether human immunodeficiency virus (HIV) status is independently associated with elevated FeNO. Methods FeNO was quantified by NIOX Vero and pulmonary function was assessed by spirometry in 432 PLWH from the Copenhagen Comorbidity in HIV Infection Study and in 1618 age- and sex-matched uninfected controls from the Copenhagen General Population Study. Elevated FeNO was defined as ≥25 parts per billion. Associations between FeNO and HIV status were adjusted for known potential confounders. Results Mean age of PLWH was 50.7 (standard deviation [SD], 11.1) years and 97.4% received combination antiretroviral therapy. PLWH had higher FeNO than uninfected controls (median, 17.0 [interquartile range {IQR}, 11.0–26.0] vs 13.0 [IQR, 9.0–19.0]; P &lt; .001). Also, PLWH had a higher prevalence of elevated FeNO than uninfected controls (27.5% vs 12.3%; P &lt; .001). This association remained after adjusting for age, sex, height, smoking status, use of airway medication, blood eosinophils, and immunoglobulin E (adjusted OR [aOR], 3.56 [95% CI, 2.51–5.04]; P &lt; .001). Elevated FeNO was associated with self-reported asthma (aOR, 2.65 [95% CI, 1.66–4.24]; P &lt; .001) but not with airflow limitation (aOR, 1.07 [95% CI, .71–1.62]; P = .745). Conclusions HIV status was independently associated with elevated FeNO, suggesting increased eosinophilic airway inflammation. The potential impact on chronic lung disease pathogenesis needs further investigation.

Abstract Background There are limited data regarding the clinical impact of coronavirus disease 2019 (COVID-19) on people living with human immunodeficiency virus (PLWH). In this study, we compared outcomes for PLWH with COVID-19 to a matched comparison group. Methods We identified 88 PLWH hospitalized with laboratory-confirmed COVID-19 in our hospital system in New York City between 12 March and 23 April 2020. We collected data on baseline clinical characteristics, laboratory values, HIV status, treatment, and outcomes from this group and matched comparators (1 PLWH to up to 5 patients by age, sex, race/ethnicity, and calendar week of infection). We compared clinical characteristics and outcomes (death, mechanical ventilation, hospital discharge) for these groups, as well as cumulative incidence of death by HIV status. Results Patients did not differ significantly by HIV status by age, sex, or race/ethnicity due to the matching algorithm. PLWH hospitalized with COVID-19 had high proportions of HIV virologic control on antiretroviral therapy. PLWH had greater proportions of smoking (P &lt; .001) and comorbid illness than uninfected comparators. There was no difference in COVID-19 severity on admission by HIV status (P = .15). Poor outcomes for hospitalized PLWH were frequent but similar to proportions in comparators; 18% required mechanical ventilation and 21% died during follow-up (compared with 23% and 20%, respectively). There was similar cumulative incidence of death over time by HIV status (P = .94). Conclusions We found no differences in adverse outcomes associated with HIV infection for hospitalized COVID-19 patients compared with a demographically similar patient group.

Abstract Elite controllers (ECs) are people living with human immunodeficiency virus (HIV) who spontaneously control viral replication without antiretroviral therapy. We observed that elevated anti-cytomegalovirus (CMV) immunoglobulin G (IgG) levels correlated with annual CD4 T-cell count decay in ECs independently of age, sex, and human leukocyte antigen (HLA) type. Elevated anti-CMV titers may favor disease progression in ECs.
