Occult hepatitis B virus infection in a Kenyan cohort of HIV infected anti-retroviral therapy naïve adults.

BACKGROUND: Occult hepatitis B virus (HBV) infection (OBI) is a phase of HBV infection characterised by the presence of HBV DNA in the absence of detectable hepatitis B surface antigen (HBsAg). OBI is of concern in the HIV-infected due to high prevalence and risk of HBV reactivation. The prevalence and clinico-demographic characteristics of OBI in anti-retroviral therapy (ART) naïve HIV infected adults in Kenya is unknown. METHODS: A cross sectional study carried was out at three sites in Kenya. HIV infected ART naïve adults were enrolled and demographic data collected. Blood samples were assayed for HBsAg, HBV DNA, alanine aminotransferase, aspartate aminotransferase, antibodies to hepatitis B surface antigen (anti-HBs) and hepatitis B core antigen (anti-HBc). Data on CD4 count, HIV viral load and platelet count were obtained from medical records. RESULTS: Of 208 patients, 199 (95.7%) did not report HBV vaccination, 196 (94.2%) were HBsAg negative, 119 (57.2%) had no HBV markers, 58 (27.9%) had previous HBV infection (anti-HBc positive) and 11 (5.3%) had OBI. All 11 (100%) OBI patients were anti-HBc positive. OBI patients comprised 19.0% of HBsAg negative, anti-HBc positive patients. There was no difference in clinico-demographic characteristics between the overt HBV, OBI and HBV negative patients. CONCLUSION: This was the first study on OBI in ART naïve HIV infected adults in Kenya. The lower OBI prevalence compared to other sub-Saharan African countries could be attributed to lower HBV exposure. Most patients were HBV unexposed and unimmunized, outlining the need to implement guideline recommended immunization strategies.

COVID-19 and the Need for Global Critical Care Training. Why Ventilators Alone Are Not the Answer.

The current coronavirus disease (COVID-19) pandemic has unearthed many weaknesses in healthcare systems worldwide. In doing so, it has caused high-income countries to deal with the uncomfortable situation of resource allocation that has long been a daily occurrence in low- and middle-income countries. The shortage of equipment continues to be a major problem in low- and middle-income countries, but there is an even greater shortage of human resources in the form of trained individuals capable of caring for critically ill patients. With physicians being in short supply in many areas throughout Africa, the question becomes where do these human resources come from? In Kenya, clinical officers are the frontline workers and backbone of care in many healthcare settings and outnumber physicians four to one. AIC Kijabe Hospital, located in rural Kenya, recognized this need and identified this cohort of clinicians as a means of ramping up local emergency and critical care. In doing so, the Emergency and Critical Care Clinical Officer training program was created in 2015. Since its inception, the Emergency and Critical Care Clinical Officer program has been training nonphysician clinicians to care for critically ill patients with physician support. In this perspective piece, we outline our attempt at capitalizing on this pool of human resources to advance the care of critically ill patients, describe lessons learned along the way, and try to highlight the utility of their unique skill set in the setting of a pandemic.
