Rationale and design of the Pan African Pulmonary hypertension Cohort (PAPUCO) study: implementing a contemporary registry on pulmonary hypertension in Africa

by Professor Kamilu M Karaye, I. Mbanze, Okechukwu Ogah, and Mahmoud Sani

BMJ Open, 2014

Pulmonary hypertension (PH) is a devastating, progressive disease with increasingly debilitating ... more Pulmonary hypertension (PH) is a devastating, progressive disease with increasingly debilitating symptoms and usually shortened overall life expectancy due to a narrowing of the pulmonary vasculature and consecutive right heart failure. Little is known about PH in Africa, but limited reports suggest that PH is more prevalent in Africa compared with developed countries due to the high prevalence of risk factors in the region. A multinational multicentre registry-type cohort study was established and tailored to resource-constraint settings to describe disease presentation, disease severity and aetiologies of PH, comorbidities, diagnostic and therapeutic management, and the natural course of PH in Africa. PH will be diagnosed by specialist cardiologists using echocardiography (right ventricular systolic pressure &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;35 mm Hg, absence of pulmonary stenosis and acute right heart failure), usually accompanied by shortness of breath, fatigue, peripheral oedema and other cardiovascular symptoms, ECG and chest X-ray changes in keeping with PH as per guidelines (European Society of Cardiology and European Respiratory Society (ESC/ERS) guidelines). Additional investigations such as a CT scan, a ventilation/perfusion scan or right heart catheterisation will be performed at the discretion of the treating physician. Functional tests include a 6 min walk test and the Karnofsky Performance Score. The WHO classification system for PH will be applied to describe the different aetiologies of PH. Several substudies have been implemented within the registry to investigate specific types of PH and their outcome at up to 24 months. Data will be analysed by an independent institution following a data analyse plan. All local ethics committees of the participating centres approved the protocol. The data will be disseminated through peer-reviewed journals at national and international conferences and public events at local care providers.

Unexpectedly high prevalence of target-organ damage in newly diagnosed Nigerians with hypertension

Untreated or poorly controlled hypertension predisposes to target-organ damage and is often followed by serious cardiovascular events. Knowledge of the type and distribution of endorgan damage in newly diagnosed hypertensive patients would help to determine the interventions or preventative measures needed in such patients. To assess target-organ involvement in newly diagnosed, untreated hypertensive patients presenting at the University College Hospital, Ibadan, Nigeria. Newly diagnosed hypertensive men and women were recruited consecutively into the study. Target-organ damage was assessed using electroctrocardiography, echocardiography, renal function assessment (including tests for albuminuria) and fundoscopy. A total of 68 subjects were recruited, but only 54 (79.4%), with a mean age of 59.1 ( +/- 12.4) years, completed the study. There were 29 ( +/- 53.7%) men, mean age 63.5 ( +/- 12.6) years, and 25 ...
