Effect Of Female Sex Work-Targeted Community-Based Interventions Along The Hiv Treatment Cascade In Sub-Saharan Africa: A Systematic Review Protocol, Lydia Atuhaire, Olatunji Adetokunboh, Constance Shumba, Peter S. Nyasulu

School of Nursing & Midwifery, East Africa

Introduction: Female sex workers (FSWs) are a known high-risk group that are at increased risk of HIV transmission due to exposure to multiple sexual partners and inability to negotiate safe sex attributed to challenging economic circumstances. Previous systematic reviews have examined the effectiveness of HIV interventions prioritising FSWs and have shown that targeted interventions improve access to HIV prevention and treatment services. Interventions that increase FSWs’ uptake of services are well documented; however, evidence on specific interventions aimed at improving FSWs’ continuity in HIV care along the treatment cascade is lacking. This systematic review aims to document the performance of …

Screening Tools For Hiv-Associated Neurocognitive Disorders Among Adults Living With Hiv In Sub-Saharan Africa: A Scoping Review, Patrick N. Mwangala, Charles R. Newton, Melanie Abas, Amina Abubakar

Institute for Human Development

Background: People living with HIV are at risk of developing HIV-associated neurocognitive disorders (HAND) which adversely affects their quality of life. Routine screening of HAND in HIV care is recommended to identify clinically important changes in cognitive functioning and allow for early interventions. However, HAND detection in routine clinical practice has never been reported in sub-Saharan Africa (SSA), partly due to a lack of adequately standardized screening tools. This review was conducted to identify the commonly used screening tools for HAND in SSA and document their psychometric properties and diagnostic accuracy.
Methods: We searched Ovid Medline, PsycINFO and Web of …

Clinic records were reviewed for mother’s antenatal HIV status. Participants were interviewed about childhood abuse including physical or …


Factors Associated With Substance Use Among Adolescents Living With Hiv In Kenya, Wambui Kagucia Oct 2018

Factors Associated With Substance Use Among Adolescents Living With Hiv In Kenya, Wambui Kagucia

Theses & Dissertations

Background: Substance use is rife in our society and adolescents (10-19 years) do face this problem during this vulnerable period of growth and development. Use of substances is known to be associated with poor health choices and risky sexual behaviour. Since the advent of antiretroviral therapy (ART), significant progress has been made with reduced rates of mother to child transmission (MTCT) and a general downward global trend in acquired immunodeficiency disease (AIDS) related mortalities. However, human immunodeficiency virus (HIV)/AIDS is still a leading cause of mortality in adolescents living in Sub Saharan Africa, with an upward trend in new HIV …

Internal Medicine, East Africa

Studies on the effects of alcohol use on HIV disease progression have been contradictory, with at least one study finding a positive effect of low alcohol consumption on CD4 count. In addition, most such studies have taken place in the developed West. We investigated the association between alcohol use and immune reconstitution through CD4 count response among HIV-infected individuals on antiretroviral therapy (ART) at an urban sub-Saharan African clinic. This was a retrospective cohort study of treatment-naïve HIV-infected adults initiating ART in Nairobi, Kenya and followed for 12 months between January 2009 and December 2012. At enrollment, a standardized questionnaire …

Obstetrics and Gynaecology, East Africa

Background: Evidence from observational studies suggests an increased risk of HIV acquisition among women using depot medroxyprogesterone acetate (DMPA) contraception.

Methods: Within the context of a South African programme to increase women's access to the intrauterine contraceptive device (IUD), we conducted a pragmatic, open-label, parallel-arm, randomised controlled trial (RCT) of the IUD versus injectable progestogen contraception (IPC) at two South African hospitals. The primary outcome was pregnancy; secondary outcomes included HIV acquisition. Consenting women attending termination of pregnancy services were randomised after pregnancy termination between July 2009 and November 2012. Condoms were promoted for the prevention of sexually transmitted infections. …

Epidemiology Of Hpv Genotypes Among Hiv Positive Women In Kenya: A Systematic Review And Meta-Analysis, Sonia Menon, Aibibula Wusiman, Marie Claude Boily, Mbabazi Kariisa, Hillary Mabeya, Stanley Luchters, Frode Forland, Rodolfo Rossi, Steven Callens, Davy Vanden Broeck

Population Health, East Africa

Background: There is a scarcity of data on the distribution of human papillomavirus (HPV) genotypes in the HIV positive population and in invasive cervical cancer (ICC) in Kenya. This may be different from genotypes found in abnormal cytology. Yet, with the advent of preventive HPV vaccines that target HPV 16 and 18, and the nonavalent vaccine targeting 90% of all ICC cases, such HPV genotype distribution data are indispensable for predicting the impact of vaccination and HPV screening on prevention. Even with a successful vaccination program, vaccinated women will still require screening to detect those who will develop ICC from …

Internal Medicine, East Africa

The burden of HIV/AIDS and other transmissible diseases is higher in prison and jail settings than in the non-incarcerated communities that surround them. In this comprehensive review, we discuss available literature on the topic of clinical management of people infected with HIV, hepatitis B and C viruses, and tuberculosis in incarcerated settings in addition to co-occurrence of one or more of these infections. Methods such as screening practices and provision of treatment during detainment periods are reviewed to identify the effect of community-based treatment when returning inmates into the general population. Where data are available, we describe differences in the …


Sonographic Estimation Of The Prevalence Of Hepatic Steatosis In Hiv Monoinfected Patients At Aga Khan University Nairobi., Bernadette Wambui Muthee May 2016

Sonographic Estimation Of The Prevalence Of Hepatic Steatosis In Hiv Monoinfected Patients At Aga Khan University Nairobi., Bernadette Wambui Muthee

Theses & Dissertations

Introduction: Human immunodeficiency virus disease (HIV) is a worldwide health problem. It is estimated that 38.6 million people are infected with HIV globally. It has remained endemic in the African continent for close to 20 years and is a long term developmental challenge in Africa which bears 69 % of the HIV/AIDS global burden.

The introduction of highly active antiretroviral therapy (HAART) has caused dramatic improvement in prognosis of HIV disease. Consequently, this has resulted in substantial reduction in Acquired Immune Deficiency Syndrome (AIDS) related morbidity and mortality. In contrast, this has been accompanied by an upsurge in liver- related …

Simplified Paper Format For Detecting Hiv Drug Resistance In Clinical Specimens By Oligonucleotide Ligation, Nuttada Panpradist, Ingrid A. Beck, Michael Chung, James N. Kiarie, Lisa M. Frenkel, Barry R. Lutz

Internal Medicine, East Africa

Human immunodeficiency virus (HIV) is a chronic infection that can be managed by antiretroviral treatment (ART). However, periods of suboptimal viral suppression during lifelong ART can select for HIV drug resistant (DR) variants. Transmission of drug resistant virus can lessen or abrogate ART efficacy. Therefore, testing of individuals for drug resistance prior to initiation of treatment is recommended to ensure effective ART. Sensitive and inexpensive HIV genotyping methods are needed in low-resource settings where most HIV infections occur. The oligonucleotide ligation assay (OLA) is a sensitive point mutation assay for detection of drug resistance mutations in HIV pol. The current …

Promoting Resilience For Hiv Prevention In Female Sex Workers In Hong Kong: A Randomised Controlled Trial, Winnie W-Y Yuen, William C-W Wong, Catherine S-K Tang, Eleanor Holroyd, Agnes F-Y Tiwari, Daniel Y-T Fong, Weng Y. Chin

School of Nursing & Midwifery, East Africa

Background: Female sex workers are considered a reservoir of HIV and their psychological health has a role to play in HIV infections. In China, commercial sex workers were reported to account for nearly 50% of heterosexual transmission of HIV. Therefore, HIV prevention targeted at mental health could be an innovative strategy in controlling the infection. We aimed to provide an evidence-based resilience-promoting intervention targeting mental health and ultimately safe sexual practices of female sex workers.

Methods: This randomised controlled trial was done at three Hong Kong non-governmental organisations, namely Action for REACH OUT, JJJ Association, and the Society of …


Respiratory Function Amongst Asymptomatic Hiv Positive And Hiv Negative Clients At Aga Khan University Hospital, Nairobi, Noah Kipkemei Murbiy Jun 2015

Respiratory Function Amongst Asymptomatic Hiv Positive And Hiv Negative Clients At Aga Khan University Hospital, Nairobi, Noah Kipkemei Murbiy

Theses & Dissertations

Background: Spirometry is used to asses respiratory function abnormalities. This is usually in reference to a validated normal range unique to a particular gender, race, age, weight and height. Majority of persons are usually asymptomatic until the expected FEV1 has decreased by 50%. Early intervention on the abnormalities even in this asymptomatic group has been shown to retard the rate of pulmonary deterioration. An unpublished audit at the Aga Khan University Hospital, Nairobi, revealed that majority of newly diagnosed HIV positive persons were admitted at the Critical Care Units with a pulmonary cause which later resulted in poor outcomes. This …

Obstetrics and Gynaecology, East Africa

Even though the elimination of congenital syphilis has been on the maternal and child health (MCH) agenda for over a decade, elimination has not yet been achieved; what, then, are the factors currently facilitating the elimination of mother-to-child transmission (MTCT) of syphilis?


Exploring Unprotected Anal Intercourse Among Newly Diagnosed Hiv Positive Men Who Have Sex With Men In China: An Ethnographic Study, Haochu Li, Eleanor Holroyd, Joseph Lau Jan 2015

Exploring Unprotected Anal Intercourse Among Newly Diagnosed Hiv Positive Men Who Have Sex With Men In China: An Ethnographic Study, Haochu Li, Eleanor Holroyd, Joseph Lau

School of Nursing & Midwifery, East Africa

Background: Unprotected anal intercourse (UAI) is a major pathway towards secondary HIV transmission among men who have sex with men (MSM). We explored the socio-cultural environment and individual beliefs and experiences conducive to UAI in the context of Southern China.

Methods: We employed an ethnographic approach utilizing a socio-ecological framework to conduct repeated in-depth interviews with thirty one newly diagnosed HIV positive MSM as well as participant observations in Shenzhen based healthcare settings, MSM venues and NGO offices.

Hiv Prevalence In Blood Donors And Recipients In Pakistan: A Meta-Analysis And Analysis Of Blood-Bank Data, Bushra Moiz, Barkat Ali, Muhammad Hasnain Chatha, Ahmed Raheem, Hasan Abbas Zaheer Jan 2015

Hiv Prevalence In Blood Donors And Recipients In Pakistan: A Meta-Analysis And Analysis Of Blood-Bank Data, Bushra Moiz, Barkat Ali, Muhammad Hasnain Chatha, Ahmed Raheem, Hasan Abbas Zaheer

Department of Pathology and Laboratory Medicine

Background:
The first instances of HIV-antibody detection in donated blood in Pakistan were reported in 1988. Since then, documentation of HIV in blood donors and of rates of transmission via transfusion has been limited. Previously assumed to have a low prevalence, HIV is an increasing health concern in Pakistan. Since there is no national, centralized blood-banking system, there are no reliable data on which to base estimated risks of transfusion-associated HIV infection. This study was therefore conducted to estimate the prevalence of HIV in blood donors and recipients in Pakistan between 1988 and 2012.
Methods:
Meta-analyses were undertaken of reported …


Achieving Pregnancy Safely In Hiv-Affected Individuals And Couples: An Important Strategy To Eliminate Hiv Transmission From Mother-To-Child And Between Sexual Partners, Mmeje Okeoma, Betty Njoroge, Craig Cohen, Marleen Temmerman, Sten H. Vermund, Sheryl Van Der Poel Jan 2015

Achieving Pregnancy Safely In Hiv-Affected Individuals And Couples: An Important Strategy To Eliminate Hiv Transmission From Mother-To-Child And Between Sexual Partners, Mmeje Okeoma, Betty Njoroge, Craig Cohen, Marleen Temmerman, Sten H. Vermund, Sheryl Van Der Poel

Obstetrics and Gynaecology, East Africa

HIV-infected individuals are living longer, more productive lives. HIV-affected individuals and couples experience personal and social desires to reproduce for all the same reasons as uninfected individuals and couples,1 and thus require safe reproductive options. HIV prevention interventions often do not consider the childbearing desires of HIV-affected individuals or couples, especially in low- and middle-income countries (LMICs). Failure to assist women with desired fertility can contribute to continued HIV transmission and must be addressed within national elimination of mother-to-child transmission (eMTCT) strategies.

A human rights perspective suggests that HIV-affected couples* should have the same ability to choose if and when …

The Impact Of Alcohol On Hiv Prevention And Treatment For South Africans In Primary Healthcare, Michelle Schneider, Matthew Chersich, Marleen Temmerman, Olivier Degomme, Charles D. Parry

Obstetrics and Gynaecology, East Africa

Background: Antiretroviral treatment (ART) has substantially reduced morbidity and mortality for HIV patients. In South Africa, with the largest ART programme globally, attention is needed not only on the further expansion of ART coverage, but also on factors which undermine its effectiveness, such as alcohol use.

Objective: Given the decentralised approach of nurse-initiated and -sustained ART in the South African primary health sector, it is important to document key aspects of alcohol use to be conveyed to HIV-positive individuals and those at risk for HIV.

Method: This study comprised a narrative review of relevant literature.

Results: Alcohol acts through both …

Identifying Factors Associated With The Uptake Of Prevention Of Mother To Child Hiv Transmission Programme In Tigray Region, Ethiopia: A Multilevel Modeling Approach, Wondwossen Lerebo, Steven Callens, Debra Jackson, Christina Zarowsky, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: Prevention of mother to child HIV transmission (PMTCT) remains a challenge in low and middle-income countries. Determinants of utilization occur – and often interact - at both individual and community levels, but most studies do not address how determinants interact across levels. Multilevel models allow for the importance of both groups and individuals in understanding health outcomes and provide one way to link the traditionally distinct ecological- and individual-level studies. This study examined individual and community level determinants of mother and child receiving PMTCT services in Tigray region, Ethiopia.

Methods: A multistage probability sampling method was used for this …
