HIV coinfections with tuberculosis among HIV-1 infected individuals in old cross river state,Nigeria

ABSTRACT

Human immunodeficiency virus (HIV) and Tuberculosis (TB) are two main global public health threats that dent development in low and middle-income countries. This study evaluated the HIV/TB co-infection rate among HIV-1 infected individuals in old Cross River State, Nigeria. A total of 417 HIV-infected individuals participated in this study, 241 (57.8%) from Calabar, Cross River State, Nigeria and 176 (42.2%) from Uyo, Akwa-Ibom State, Nigeria. The age range of the 417 HIV-1 positive individuals who participated in the study was 4–72 years with an average age of 39.1 years. Plasma samples were analyzed for HIV and TB using fourth-generation Enzyme-Linked immunosorbent Assay. The CD4 count was enumerated using the Partec CyFlow® Counter. Plasma viral loads (PVL) were determined using the Abbott Real-Time HIV-1 assay. Results showed that 230 (55.2%) of the participants were in the 31–45 years age range. The majority (67.4%) of the HIV-1 infected individuals were females and 32.6% were males. An overall prevalence of HIV/TB coinfection in Old Cross River State, Nigeria was 1.4%, with Akwa Ibom State (0.6%) and Cross River State (1.2%). A higher prevalence of HIV/TB coinfection was observed among females (1.8%) than in males (0.7%). Higher prevalences of HIV/TB coinfections was observed in patients above 45 years of age (2.2%), married (2.3%), tertiary education (1.8%) followed by those with secondary education (1.4%), traders and civil servants (3.1%), patients with CD4 counts 200–349 and ≥500 cells/μl (1.9%), and those with viral load <40 copies/mL (2.7%). This study confirmed the presence of HIV/TB co-infection in old Cross River State, Nigeria. Although the prevalence rate of HIV/TB coinfection was low, its presence alone among HIV-1 infected individuals makes it a major source of concern. This finding highlights the need for a well-structured approach to the management of co-infection, and this includes both the social and medical aspects of the problem.     

Living well with kidney disease by patient and care-partner empowerment: Kidney health for everyone everywhere

Living with chronic kidney disease (CKD) is associated with hardships for patients and their care-partners. Empowering patients and their care-partners, including family members or friends involved in their care, may help minimize the burden and consequences of CKD related symptoms to enable life participation. There is a need to broaden the focus on living well with kidney disease and re-engagement in life, including an emphasis on patients being in control. The World Kidney Day (WKD) Joint Steering Committee has declared 2021 the year of “Living Well with Kidney Disease” in an effort to increase education and awareness on the important goal of patient empowerment and life participation. This calls for the development and implementation of validated patient-reported outcome measures to assess and address areas of life participation in routine care. It could be supported by regulatory agencies as a metric for quality care or to support labelling claims for medicines and devices. Funding agencies could establish targeted calls for research that address the priorities of patients. Patients with kidney disease and their care-partners should feel supported to live well through concerted efforts by kidney care communities including during pandemics. In the overall wellness programme for kidney disease patients, the need for prevention should be reiterated. Early detection with a prolonged course of wellness despite kidney disease, after effective secondary and tertiary prevention programmes, should be promoted. WKD 2021 continues to call for increased awareness of the importance of preventive measures throughout populations, professionals, and policy makers, applicable to both developed and developing countries.     

Effects of exercise training on bone mineral density and some health-related outcomes in HIV conditions: A randomized controlled trial

Introduction:Human Immunodeficiency Virus (HIV) infection remains prevalent co-morbidity, and among fracture patients. Few studies have investigated the role of exercise interventions in preventing bone demineralization in people who have fractures and HIV. If exercise exposed, HIV-infected individuals may experience improved bone health outcomes (BMD), function, quality of life (QoL). The study will aim to assess the impact of home based exercises on bone mineral density, functional capacity, QoL, and some serological markers of health in HIV infection among Nigerians and South Africans.Methods and design:The study is an assessor-blinded randomized controlled trial. Patients managed with internal and external fixation for femoral shaft fracture at the study sites will be recruited to participate in the study. The participants will be recruited 2 weeks post-discharge at the follow-up clinic with the orthopaedic surgeon. The study population will consist of all persons with femoral fracture and HIV-positive and negative (HIV-positive medically confirmed) aged 18 to 60 years attending the above-named health facilities. For the HIV-positive participants, a documented positive HIV result, as well as a history of being followed-up at the HIV treatment and care center. A developed home based exercise programme will be implemented in the experimental group while the control group continues with the usual rehabilitation programme. The primary outcome measures will be function, gait, bone mineral density, physical activity, and QoL.Discussion:The proposed trial will compare the effect of a home-based physical exercise-training programme in the management of femoral fracture to the usual physiotherapy management programmes with specific outcomes of bone mineral density, function, and inflammatory markers.Trial registration:The study was prospectively registered with the Pan African Clinical Trials Registry (Reference number – PACTR201910562118957) on October 21, 2019.

The immunology of Leishmania/HIV co-infection

Leishmaniases are emerging as an important disease in human immunodeficiency virus (HIV)–infected persons living in several sub-tropical and tropical regions around the world, including the Mediterranean. The HIV/AIDS pandemic is spreading at an alarming rate in Africa and the Indian subcontinent, areas with very high prevalence of leishmaniases. The spread of HIV into rural areas and the concomitant spread of leishmaniases to suburban/urban areas have helped maintain the occurrence of Leishmania/HIV co-infection in many parts of the world. The number of cases of Leishmania/HIV co-infection is expected to rise owing to the overlapping geographical distribution of the two infections. In Southwestern Europe, there is also an increasing incidence of Leishmania/HIV co-infection (particularly visceral leishmaniasis) in such countries as France, Italy, Spain and Portugal. Studies suggest that in humans, very complex mechanisms involving dysregulation of host immune responses contribute to Leishmania-mediated immune activation and pathogenesis of HIV. In addition, both HIV-1 and Leishmania infect and multiply within cells of myeloid or lymphoid origin, thereby presenting a perfect recipe for reciprocal modulation of Leishmania and HIV-1-related disease pathogenesis. Importantly, because recovery from leishmaniases is associated with long-term persistence of parasites at the primary infection sites and their draining lymph nodes, there is very real possibility that HIV-mediated immunosuppression (due to CD4⁺ T cell depletion) could lead to reactivation of latent infections (reactivation leishmaniasis) in immunocompromised patients. Here, we present an overview of the immunopathogenesis of Leishmania/HIV co-infection and the implications of this interaction on Leishmania and HIV disease outcome.     

Incidence of postoperative pain after use of calcium hydroxide mixed with normal saline or 0.2% chlorhexidine digluconate as intracanal medicament in the treatment of apical periodontitis

Objective

To compare the incidence of postoperative pain after the use of calcium hydroxide powder mixed with normal saline or 0.2% chlorhexidine digluconate as intracanal medicament.

Participants

Fifty-five subjects aged 17–60 years with teeth diagnosed to have apical periodontitis.

Intervention

Two-visit conventional root canal treatment of seventy teeth. The teeth were divided by randomization (balloting) into two groups: control group and experimental group, each with thirty-five teeth treated with calcium hydroxide mixed with normal saline or with 0.2% chlorhexidine digluconate as intracanal medicament respectively. Incidence of postoperative pain was assessed using the universal pain assessment tool and whether or not analgesic was taken.

Main outcome measured

Incidence of post-operative pain.

Result

Postoperative pain occurred only at 1-day and 1-week reviews. In the control group, the overall incidence of pain was the same at both review periods (5.7%), while the experimental group showed a slight decrease in incidence between 1-day (17.2%) and 1-week (11.4%) reviews. Incidence of flare-ups was more in the experimental group (11.4%) than in the control group (5.7%). No significant statistical differences between the two groups were observed (p > 0.05).

Conclusion

The incidence of postoperative pain was lower in the normal saline treatment group, but the difference was not statistically significant.     

A cross-sectional study of the knowledge and attitude of medical laboratory personnel regarding continuing professional development

Background:

Continuing professional development (CPD) in Medical Laboratory Scientists (MLS) is aimed at equipping laboratory professionals with the necessary skills to enhance practice. The laboratory scientists are usually the first contact between the patient and health care system in aspects of diagnosis and monitory of diseases. As such, it becomes imperative to assess the knowledge of laboratory personnel regarding CPD.

Materials and Methods:

Self-administered questionnaires were distributed to 200 laboratory personnel''s attending the maiden CPD workshop organized by the Association of MLS in Jos the Plateau state capital.

Results:

One hundred and thirty-five (82 males and 53 females) of the 200 administered questionnaires were returned. Only 32 of them (23.7%) attended CPD program in the last 1 year with 10 (7.5%) engaging in online CPD. Five (3.7%) of the respondents had the privilege to attend an international CPD. Majority (95.2%) of the respondents identified CPD as an essential component of professional career development. Lack of sponsorship was identified as a major setback in CPD efficiency by 93.8% of respondents. About 58 (46.4%) noted that poor attendance in CPD workshops was due to unavailability of policy guideline for CPD. One hundred and twenty (95.2%) of respondents had an aim of improving their skills after attending CPD workshops.

Conclusion:

The overall attitude of Nigerian MLS toward attending CPD workshop is poor; however, the knowledge regarding the importance of CPD is adequate. There exists a gap between sponsorship for CPD by various institutions and MLS.
