Nutrition indicators as potential predictors of AIDS-defining illnesses among ARV-naive HIV-positive adults in Kapiri Mposhi, Zambia 2008-2009.

ABSTRACT: Early changes in nutritional status may be predictive of subsequent HIV disease progression in people living with HIV (PLHIV). In addition to conventional anthropometric assessment using body mass index (BMI) and mid-upper arm circumferences (MUAC), measures of strength and fatigability may detect earlier changes in nutrition status which predict HIV disease progression. This study aims to examine the association between various nutritional metrics relevant in resource-scarce setting and HIV disease progression. The HIV disease progression outcome was defined as any occurrence of an incident AIDS-defining illnesses (ADI) among antiretroviral treatment (ART)-naïve PLHIV. From 2008-2009, HIV+ Zambian adult men and non-pregnant women were followed for 9 months at a Doctors without Borders (Medecins Sans Frontiers, MSF) HIV clinic in Kapiri Mposhi, Zambia. Since the study was conducted in the time period when former WHO recommendations on ART (i.e., ?200 CD4 cell count as opposed to treating all individuals regardless of CD4 cell count or disease stage) were followed, caution should be applied when considering the implications from this study's results to improve HIV case management under current clinical guidelines, or when comparing findings from this study with studies conducted in recent years. Bivariable and multivariable logistic regression was used to assess the associations between baseline nutritional measurements and the outcome of incident ADI. Self-reported loss of appetite study (AOR 1.90, 95% CI 1.04, 3.45, P = 0.036) and moderate wasting based on MUAC classification (AOR 2.40, 95% CI 1.13, 5.10, P = 0.022) were independently associated with increased odds of developing incident ADI within 9 months, while continuous increments (in psi) of median handgrip strength (AOR 0.74, 95%CI 0.60, 0.91, P = 0.004) was independently associated with decreased odds of incident ADI only among women. The association between low BMI and the short-term outcome of ADI was attenuated after controlling for these nutritional indicators. These findings warrant further research to validate the consistency of these observed associations among larger ART-naïve HIV-infected populations, as well as to develop nutritional assessment tools for identifying disease progression risk among ART-naïve PLHIV.

Project description:BackgroundIn Madagascar, despite an influenza surveillance established since 1978, little is known about the etiology and prevalence of viruses other than influenza causing influenza-like illnesses (ILIs).Methodology/principal findingsFrom July 2008 to June 2009, we collected respiratory specimens from patients who presented ILIs symptoms in public and private clinics in Antananarivo (the capital city of Madagascar). ILIs were defined as body temperature ?38°C and cough and at least two of the following symptoms: sore throat, rhinorrhea, headache and muscular pain, for a maximum duration of 3 days. We screened these specimens using five multiplex real time Reverse Transcription and/or Polymerase Chain Reaction assays for detection of 14 respiratory viruses. We detected respiratory viruses in 235/313 (75.1%) samples. Overall influenza virus A (27.3%) was the most common virus followed by rhinovirus (24.8%), RSV (21.2%), adenovirus (6.1%), coronavirus OC43 (6.1%), influenza virus B (3.9%), parainfluenza virus-3 (2.9%), and parainfluenza virus-1 (2.3%). Co-infections occurred in 29.4% (69/235) of infected patients and rhinovirus was the most detected virus (27.5%). Children under 5 years were more likely to have one or more detectable virus associated with their ILI. In this age group, compared to those ?5 years, the risk of detecting more than one virus was higher (OR?=?1.9), as was the risk of detecting of RSV (OR?=?10.1) and adenovirus (OR?=?4.7). While rhinovirus and adenovirus infections occurred year round, RSV, influenza virus A and coronavirus OC43 had defined period of circulation.ConclusionsIn our study, we found that respiratory viruses play an important role in ILIs in the Malagasy community, particularly in children under 5 years old. These data provide a better understanding of the viral etiology of outpatients with ILI and describe for the first time importance of these viruses in different age group and their period of circulation.

Project description:In order to achieve the programmatic goals established in the National HIV/AIDS Strategy, virologic suppression remains the most important outcome within the HIV care continuum for individuals receiving antiretroviral therapy (ART). Therefore, clinicians have dedicated substantial resources to improve adherence and clinic retention for individuals on ART; however, these efforts should be focused first on those most at risk of morbidity and mortality related to AIDS. Our study aimed to characterize the factors that are associated with AIDS-defining illnesses (ADIs) amongst people living with HIV (PLHIV) who are poorly adherent or retained in care in order to identify those at highest risk of poor clinical outcomes. We recruited 99 adult PLHIV with a history of poor adherence to ART, poor clinic attendance, or unsuppressed viral load (VL) from the Infectious Disease Program (IDP) of the Grady Health System in Atlanta, Georgia between January and May 2011 to participate in a survey investigating the acceptability of a financial incentive for improving adherence. Clinical outcomes including the number of ADI episodes in the last five years, VLs, and CD4 counts were abstracted from medical records. Associations between survey items and number of ADIs were performed using chi-square analysis. In our study, 36.4% of participants had ?1 ADI in the last five years. The most common ADIs were Pneumocystis jirovecii pneumonia, recurrent bacterial pneumonia, and esophageal candidiasis. Age <42.5 years (OR 2.52, 95% CI = 1.08-5.86), male gender (OR 3.51, 95% CI = 1.08-11.34), CD4 nadir <200 cells/µL (OR 11.92, 95% CI = 1.51-94.15), unemployment (OR 3.54, 95% CI = 1.20-10.40), and travel time to clinic <30 minutes (OR 2.80, 95% CI = 1.20-6.52) were all significantly associated with a history of ?1 ADI in the last five years. Awareness of factors associated with ADIs may help clinicians identify which poorly adherent PLHIV are at highest risk of HIV-related morbidity.

Project description:Background and introduction Human immune deficiency virus (HIV) infection remains a major health problem since discovery of the virus in 1981. Globally, since introduction of antiretroviral therapy, AIDS-related mortality was reduced by 47% since 2010. Also, HIV-related opportunistic infections (OIs) became less common, especially with use of prophylaxis to prevent such infections. In this study, we aim to assess the incidence of HIV infection and related OIs in Qatar for 17-year period, and to assess the spectrum of these infections, risk factors and treatment outcomes. Methods This is a retrospective cohort study for all HIV infected patients registered in the state of Qatar from 2000 to 2016. Incidence of HIV infection and related opportunistic illness was calculated per 100,000 population. Demographic and Clinical characteristic were compared between two groups of patients with and without opportunistic illness. Results of 167 cases with HIV infection 54 (32.3%) had opportunistic illness. The average incidence rate of HIV infection over 17 years is 0.69 per 100,000 population, and the incidence rate for opportunistic illness is 0.27 per 100,000 population. The most common opportunistic illness is pneumocystis jirovecii pneumonia (PCP) which constituted 25% of cases, followed by cytomegalovirus (CMV) retinitis 7.2%, Tuberculosis 5.4%, Toxoplasmosis 4.2% and, less than 2% for each of Kaposi sarcoma, lymphoma and cryptococcal infection. The outcome of treatment of cases with opportunistic illness showed cure rates of 59.3%, one year relapse rates of 8.76% and overall, 90-day mortality of 3.7% however, 33.4% of patients left the country before completion of therapy. Most of our patients in both groups were of young age, majority males, and almost half of them were Qatari. The CD4 count, CD4%, CD4/CD8 ratio and viral load were statistically significant risk factors in cases with opportunistic illness with a p value < 0.05, however presence of comorbidities was lower in patients with opportunistic illness P value of 0.032. Conclusion Qatar has a low prevalence rate for HIV infection and related opportunistic illness. Early diagnosis and use of antiretroviral therapy are important measures to decrease the rate of opportunistic illness. Highlights • HIV is a widely spread infection with special interest to public health.• HIV-related morbidity is associated with a large burden to health systems.• It is associated with opportunistic infections that affect all body systems.• Population-based studies are essential for understanding its complications.
