Country Incidence Prevalence Country Incidence Prevalence U.S ,403 U.S ,403 U.K U.K Europe Europe Nigeria Unknown 2.5 Nigeria Unknown 2.5 N.B. Incidence and prevalence are expressed in per million population 8per year. Endstage Renal Failure however 3 – 4 times more common in blacks than in caucasians. It is estimated that by 2030 more than 2 million people in the USA will need dialysis or transplantation for kidney failure.

Impact of CKD In Nigeria Population figures not available but based on hospital figures Population figures not available but based on hospital figures ESRF accounts for 1.6-8% of hospital admission rates. ESRF accounts for 1.6-8% of hospital admission rates. Mortality is over 90% within 3 months[about 11.4% of all admissions in the medical wards of a tertiary health institution in Nigeria]. Mortality is over 90% within 3 months[about 11.4% of all admissions in the medical wards of a tertiary health institution in Nigeria]. Less than 1% are able to afford renal transplant. Less than 1% are able to afford renal transplant.

Common Causes of CKD - There are many aetiological factors that have been identified as causes of CKD. - However the prevalence of these factors differ to varying extents in different parts of the world. - Some of the causes include: - Chronic glomerulonephritis - Hypertension - Diabetes - Ingestion of herbal concoction. - Analgesic nephropathy - Exposure to heavy metals. - HIV –associated nephropathy. - Infections - Sickle cell nephropathy.

Harmful Socio cultural practices] Some sociocultural practices that can lead directly or indirectly to CKD. Some sociocultural practices that can lead directly or indirectly to CKD.

Clinical Presentations CKD is silent & asymptomatic in the early stage.Most cases therefore present in the advanced stage. CKD is silent & asymptomatic in the early stage.Most cases therefore present in the advanced stage. Presentation in early stage: Presentation in early stage: -Incidental finding of abnormalty in renal marker during health screening exercises i preadmission/preemployment medical tests ii during investigation for other disease conditions. - Pain in the loins/renal angles. - Passage of stones or ‘gravel’in urine. - Unexplained growth retardation in the young. - Haematuria. - Polyuria/Nocturia/Enuresis in children.

Clinical Presentations[Cont’d] Presentations in advanced stage Presentations in advanced stage Clinical: Clinical: GIT- Nausea, vomiting,hiccups. GIT- Nausea, vomiting,hiccups.

Burden of CKD Chronic kidney disease is now a worldwide public health concern. Chronic kidney disease is now a worldwide public health concern. There is evidence of an increasing incidence and prevalence of kidney failure,with both high costs and poor outcomes of treatment.

It should be noted that CKD is grossly underdiagnosed both in our environment and even in the developed world. It should be noted that CKD is grossly underdiagnosed both in our environment and even in the developed world. This is due, to a large extent, to its silent and asymptomatic nature in the early stages, as a result of which most patients only present in the advanced stages of disease.

Burden of CKD[Cont’d] The cost of treatment of ESRD is enormous and cannot be easily accommodated within the government health budgetary allocations in developing countries. The cost of treatment of ESRD is enormous and cannot be easily accommodated within the government health budgetary allocations in developing countries. It should be noted that renal diseases is not accommodated in NHIS. It should be noted that renal diseases is not accommodated in NHIS. Hence emphasis should be laid on prevention of CKD rather than treatment which is not only expensive but also has poor outcome.

Prevention of CKD ‘Prevention, they say is better than cure’ this is very relevant in the case of CKD. ‘Prevention, they say is better than cure’ this is very relevant in the case of CKD. Successful prevention depends on the knowledge of causation, dynamic of transmission and identified risk factors. Successful prevention depends on the knowledge of causation, dynamic of transmission and identified risk factors. There are 4 levels of prevention viz: There are 4 levels of prevention viz: Primordial Primordial Primary Primary Secondary Secondary Tertiary Tertiary

Primary Prevention This aim at preventing kidney disease from occuring at all and calls for knowledge of: This aim at preventing kidney disease from occuring at all and calls for knowledge of: - risk factors predisposing to renal disease - risk factors predisposing to renal disease - risk factors that initiate renal damage - modification,removal or avoidance of risk factors. - Development of a positive health seeking attitude & behaviour.

Secondary Prevention This aim at identifying factors that aid or hasten progression of kidney disease and/or accelerate loss of kidney function and preventing or removing such factors. This aim at identifying factors that aid or hasten progression of kidney disease and/or accelerate loss of kidney function and preventing or removing such factors. While a few of those factors are not modifiable,majority of them could be modified,controlled or completely avoided. While a few of those factors are not modifiable,majority of them could be modified,controlled or completely avoided. Some of the factors include: Some of the factors include: - Increasing proteinuria - Elevated or uncontrolled blood pressure - Poor glycaemic control in diabetics - Smoking - NSAID’S - Herbal preparations - Dehydration - Infections

Tertiary Prevention A.This aim at preventing the development of complications of CKD such as: - Cardiovascular events- CCF, MI. - Dyslipidaemia. - Metabolic bone disease. - Anaemia. - Neuropathies. B.Adaptation to incurable diseases. C.Prosthesis provision D.Rehabilitation.

Recommendations Targeted screening of at risk population. Targeted screening of at risk population. At risk population are people with one or more risk factors.

Recommendations[Cont’d] Avoidance of infections- STI[viral],HBV, and UTI. Avoidance of infections- STI[viral],HBV, and UTI. Non- communicable disease tend to have multifactorial causation usually classified as: Non- communicable disease tend to have multifactorial causation usually classified as: - Modifiable- factors that we have control over e.g. hypertension, diabetes, smoking, alcohol, obesity. - Non- modifiable- factors that we have no control over e.g. age, gender, family history. - Need to cultivate positive attitude to routine check up.
