Preliminary Study on Open Labelled Randomized Controlled Trial of the Safety and Efficacy of Hydroxychloroquine and Chloroquine Phosphate for the Treatment of Persons Infected with 2019 Coronavirus Disease in Nigeria

BACKGROUND

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a causative agent of COVID-19 is a leading cause of ill-health and deaths worldwide. Currently, COVID-19 has no known widely approved therapeutics. Thus, the need for effective treatment.

OBJECTIVES

We investigated the safety and efficacy of two (2) therapeutic agents; chloroquine phosphate (CQ), 2- hydroxychloroquine (HCQ) and a control (standard supportive therapy) among hospitalized adults with COVID-19.

METHODS

The clinical trial was done in accordance to the World Health Organization master protocol for investigational therapeutics for COVID-19. Atotal of 40 participants with laboratory-confirmed positive COVID-19 were enrolled. Blood samples and oropharyngeal (OP) swabs were obtained on days 1,3,15 and 29 for safety and efficacy assessments.

RESULTS

The baseline demographics showed that the median ages in years (range) were 45 (31-57) in CQ, 45 (36.5-60.5) in HCQ, 43 (39.5-67.0) and 44.5 (25.3-51.3) in the control (P<0.042).At randomization, seven (7) participants were asymptomatic, thirty-three (33) had mild symptoms, eight (8) had moderate symptoms while three (3) had severe symptoms. The average day of conversion to negative COVID-19 was 15.5 days for CQ, 16 days for HCQ and 18 days for the control(P=0.036).

CONCLUSION

The safety assessment revealed no adverse effect of the drugs in COVID-19 patients after treatment. These findings proved that chloroquine and hydroxychloroquine are effective for the treatment of COVID-19 among hospitalized adults. It also confirmed that they are safe.

An Unstructured Supplementary Service Data System to Verify HIV Self-Testing Among Nigerian Youths: Mixed Methods Analysis of Usability and Feasibility

BACKGROUND

Mobile health (mHealth) interventions among adolescents and young adults (AYAs) are increasingly available in African low- and middle-income countries (LMICs). For example, the unstructured supplementary service data (USSD) could be used to verify HIV self-testing (HIVST) among AYAs with poor bandwidth.

OBJECTIVE

The aim of this study is to describe the creation of an USSD platform and determine its feasibility and usability to promote the verification of HIVST results among AYAs in Nigeria.

METHODS

We developed and evaluated a USSD platform to verify HIVST results using a user-centered approach. The USSD platform guided AYAs in performing HIVST, interpreting the result, and providing linkage to care after the test. Following the usability assessment, the USSD platform was piloted. We used a mixed methods study to assess the platform's usability through a process of quantitative heuristic assessment, a qualitative think-aloud method, and an exit interview. Descriptive statistics of quantitative data and inductive thematic analysis of qualitative variables were organized.

RESULTS

A total of 19 AYAs participated in the usability test, with a median age of 19 (IQR 16-23) years. There were 11 females, 8 males, and 0 nonbinary individuals. All individuals were out-of-school AYAs. Seven of the 10 Nielsen usability heuristics assessed yielded positive results. The participants found the USSD platform easy to use, preferred the simplicity of the system, felt no need for a major improvement in the design of the platform, and were happy the system provided linkage to care following the interpretation of the HIVST results. The pilot field test of the platform enrolled 164 out-of-school AYAs, mostly young girls and women (101, 61.6%). The mean age was 17.5 (SD 3.18) years, and 92.1% (151/164) of the participants reported that they were heterosexual, while 7.9% (13/164) reported that they were gay. All the participants in the pilot study were able to conduct HIVST, interpret their results, and use the linkage to care feature of the USSD platform without any challenge. A total of 7.9% (13/164) of the AYAs had positive HIV results (reactive to the OraQuick kit).

CONCLUSIONS

This study demonstrated the usability and feasibility of using a USSD system as an alternative to mobile phone apps to verify HIVST results among Nigerian youth without smartphone access. Therefore, the use of a USSD platform has implications for the verification of HIVST in areas with low internet bandwidth. Further pragmatic trials are needed to scale up this approach.

Intimate Partner Violence and Risk Factors among Women during the COVID-19 Movement Restriction in Nigeria: An Online Survey

BACKGROUND

The rapid spread of the SARS-CoV-2 infection in the absence of treatment or the presence of vaccines is forcing nations to respond with strong preventive measures ranging from mitigation, containment, and in extreme cases, quarantines. While these measures are a useful measure of infection control, they can lead to significant social, economic, and psychological consequences. This study sought to establish the prevalence and risk factors of intimate partner violence during the COVID-19 movement restriction in Nigeria among girls and women.

METHODS

An online-based questionnaire survey using Google Forms was conducted over four weeks among girls and women aged 15 years and above. Data analysis was performed using SPSS version 20, and logistic regression was used to determine risk factors for IPV experience during the lockdown.

RESULTS

Overall, 32.8% of respondents reported ever experiencing IPV, and 42.5% experienced IPV during the lockdown. Verbal (35.1%) and psychological (24.1%) violence were the commonest forms of violence in the study. There was considerable overlap between the various forms of IPV in the study. Age less than 35 years (aOR = 1.3; CI = 1.2 - 1.4), resident in the northeast region (aOR=1.6; CI=1.41.9), alcohol (aOR=1.3;CI=1.2-1.5) and substance (aOR = 1.5; CI = 1.3 - 1.8) use, average family monthly income < $100 (aOR = 1.4;CI=1.2 - 1.5), daily or weekly income (aOR = 2.7; CI = 2.5-3.1) had an increased association with IPV during the lockdown, residency in the southeast region had lower odds of experiencing IPV (aOR=.0.5; CI = 0.3-0.8).

CONCLUSION

The reported lockdown prevalence of IPV was 42.8%, with verbal and psychological violence being the most prevalent form of IPV. Age less than 35 years, resident in northeast and southeast, use of alcohol or substances, average family monthly income < $100, and partner being a daily-weekly earner was associated with IPV experience. Policymakers in the future should consider the consequences, including IPV, before issuing such an order.

Training primary healthcare workers on a task-strengthening strategy for integrating hypertension management into HIV care in Nigeria: implementation strategies, knowledge uptake, and lessons learned

BACKGROUND

With improved access to anti-retroviral drugs, persons living with HIV/AIDS (PLWHA) are living longer but with attendant increased risks of non-communicable diseases (NCDs). The increasing burden of NCDs, especially hypertension, could reverse gains attributed to HIV care. Nurses and Community Health Officers (CHO) in Nigeria are cardinal in delivering primary health care. A task-strengthening strategy could enable them to manage hypertension in HIV care settings. This study aimed to assess their knowledge and practice of hypertension management among Healthcare workers (HCWs) and to explore the challenges involved in conducting onsite training during pandemics.

METHODS

Nurses and CHOs in the employment of the Lagos State Primary Health Care Board (LSPHCB), Lagos State, Nigeria, were recruited. They were trained through hybrid (virtual and onsite) modules before study implementation and a series of refresher trainings. A pre-and post-training test survey was administered, followed by qualitative interviews to assess skills and knowledge uptake, the potential barriers and facilitators of task-sharing in hypertension management in HIV clinics, and the lessons learned.

RESULTS

Sixty HCWs participated in the two-day training at baseline. There was a significant improvement in the trainees' knowledge of hypertension management and control. The average score during the pre-test and post-test was 59% and 67.6%, respectively. While about 75% of the participants had a good knowledge of hypertension, its cause, symptoms, and management, 20% had moderate knowledge, and 5% had poor knowledge at baseline. There was also an increase in the mean score between the pre-test and post-test of the refresher training using paired t-tests (P < 0.05). Role-playing and multimedia video use improved the participants' uptake of the training. The primary barrier and facilitator of task sharing strategy in hypertension management reported were poor delineation of duties among HCWs and the existing task shifting at the Primary Healthcare Centres (PHC) level, respectively.

CONCLUSIONS

The task strengthening strategy is relevant in managing hypertension in HIV clinics in Nigeria. The capacity development training for the nurses and CHOs involved in the Integration of Hypertension Management into HIV Care in Nigeria: A Task Strengthening Strategy (TASSH-Nigeria) study yielded the requisite improvement in knowledge uptake, which is a reassurance of the delivery of the project outcomes at the PHCs.

Risks of cardio-vascular diseases among highly active antiretroviral therapy (HAART) treated HIV seropositive volunteers at a treatment centre in Lagos, Nigeria

Introduction

highly active antiretroviral therapy (HAART) has led to a decline in HIV-induced morbidity and mortality in recent years. However, it has been opined that this has led to elevated risks of cardiovascular diseases (CVDs). This study assessed the risks of CVDs among HAART experienced individuals living with HIV.

Methods

a cross sectional study involving 196 adults consisting of 118 HAART experienced and 78 HAART naïve was conducted. Anthropometric and blood pressure measurements were recorded for all participants. Blood samples obtained from the volunteers were used to determine glucose, creatinine, HIV viral load, CD4 count and lipid profile using standard methods. Lipid ratios, atherogenic indices and QRISK3 risk score were calculated.

Results

the median CD4 lymphocyte, mean body mass index (BMI) and HDL-c in HAART experienced participants were higher (P<0.05) than HAART naive individuals. The QRISK3 risk score and creatinine were higher (p<0.05) among HAART experienced group. In HAART experienced group, the risk of hypertension, increased low-density lipoprotein (LDL-c), atherogenic index of plasma (AIP) and QRISK3 were 3.7, 2.0, 2.38 and 3.85 times (p<0.05) higher respectively than in HAART naive. Atherogenic coefficient (AC) increase was more prevalent among male (p<0.05) participants. Risk of chronic renal disease (eGFR), hypertension and CVD (as measured by QRISK3) was higher (p<0.05) among the female and older participants respectively.

Conclusion

the risk of CVDs and renal disease appeared to be higher among HAART experienced volunteers and older (>45 years) volunteers. The risk of renal disease appeared higher in females.

Prevalence and Clinical Characteristics of Coronavirus Disease 2019 Seen at a Testing Centre in Lagos Nigeria

BACKGROUND

The SARS-CoV-2 infection continues to ravage the global community since it was declared a pandemic. The socio-demographic and clinical characteristics defining the disease are mainly from Europe and Asia. The disease symptomatology is similar to the prevalent diseases in our environment, this could result in the delay in prompt identification and appropriate management of suspected cases toward combating community transmission. This study evaluates the prevalence, socio-demographic and clinical characteristics of positive cases of COVID -19.

METHODS

This was a retrospective cohort study. Data on the socio-demographic, clinical characteristics and the results of the SARS-CoV-2 test of participants at the Nigerian Institute of Medical Research [NIMR] Modified Drive-through Centre for COVID-19 test sample collection over two months [24th February 2020- 27th April 2020] were retrieved from the electronic medical records (EMR). Data obtained were analyzed using SPSS version 22.0.

RESULTS

A total number of 481 clients were evaluated in this review. The prevalence of SARS-CoV-2 infection in the population was 14.6%. The mean age of the positive cases was 42.2 [±15.9] years. The common symptoms reported by the positive cases were fever (40.0%), cough (32.9%), sore throat (17.1%) and running nose (15.7%). Fever depicted statistical significance with positive cases with the majority being of mild to moderate clinical severity.

CONCLUSION

The prevalence of SARS-CoV-2 infection among this cohort was 14.6% with a male preponderance. Fever and sore throat were the variables that predicted SARS CoV-2 infection among our cohort.

Pregnancy, obstetric and neonatal outcomes in HIV positive Nigerian women

While the effect of HIV infection on some maternal outcomes is well established, for some others there is conflicting information on possible association with HIV. In this study we investigated pregnancy and neonatal outcome of HIV positive women in large HIV treatment centre over a period of 84 months. They were managed according to the Nigerian PMTCT protocol. Adverse obstetric and neonatal outcome were observed in 48.3% HIV positives compared 30.3% to the negatives (OR: 2.08; CI: 1.84-2.34). Low birth weight ( OR:2.95; CI:1.95-3.1), preterm delivery (OR:2.05; CI:1.3-3.1), perinatal death (OR:1.9;CI:1.3-3.2), and spontaneous abortion (OR:1.37; CI:1.1-2.3) were factors found to be independently associated with HIV. Low CD4 count (OR: 2.45; CI: 1.34- 4.56) and opportunistic infections (OR: 2.11; CI: 1.56-3.45) were to be associated with adverse obstetric and neonatal outcome. This study confirms the association of HIV, severe immunosuppression and opportunistic infection and adverse obstetric and neonatal outcome.

The burden of anaemia and associated factors in HIV positive Nigerian women

BACKGROUND

Anaemia is the most common complication of pregnancy and a predictor of poor maternal and foetal outcomes. HIV infection is now recognized as one of the major contributors to anaemia in pregnancy. It is therefore important to determine the burden and risk factors of anaemia in maternal HIV infection in others to plan effective prevention strategies as well as optimize management outcomes.

OBJECTIVE

To determine the prevalence and risk factors of anaemia in pregnant HIV positive Nigerians.

METHODS

The prevalence and possible risk factors of anaemia were investigated in HIV positive pregnant Nigerian women at a large HIV treatment clinic in southwestern Nigeria using a cross-sectional design between January 2006 and December 2011.

RESULTS

Nine hundred and eighty-five (42.5 %) women of 2,318 HIV positive pregnant women seen during the period were anaemic by WHO standard defined by haemoglobin <11 g/dl. Majority were of mild to moderate severity (97.9 %). Short inter birth interval (p = 0.002), presence of opportunistic infections (OIs), (p = 0.001), use of zidovudine containing regimen (p = 0.0005) and CD4 cell count <200 cells/mm(3) (p = 0.001) were found to be independently associated with anaemia in HIV positive pregnant women after controlling for confounding variables.

CONCLUSION

Anaemia was found to be high at 42.5 % among the HIV positive women studied and was found to be independently associated with short inter birth interval, presence of OIs, advanced HIV disease and use of zidovudine containing HAART regimen.
