Export selected to Endnote. The syndrome is characterized by impaired amelogenesis of the hypoplastic type and nephrocalcinosis, presenting with presence of thin or absence of enamel, late dental eruption, intrapulpal calcifications, bilateral nephrocalcinosis, and normal plasma calcium level. The objective is to characterize ERS by systematically literature reviewing, highlighting the main findings of the syndrome to increase knowledge about this condition in the health professionals. The study is a systematic review of the scientific literature, whose research was developed in the PubMed database in March A total of 69 articles were found.

Chronic kidney disease CKD is a type of kidney disease in which there is gradual loss of kidney function over a period of months to years. Causes of chronic kidney disease include diabetes , high blood pressure , glomerulonephritis , and polycystic kidney disease. Screening at-risk people is recommended. Chronic kidney disease affected million people globally in million females and million males.

CKD is initially without symptoms, and is usually detected on routine screening blood work by either an increase in serum creatinine , or protein in the urine. As the kidney function decreases:. The three most common causes of CKD in order of frequency as of are diabetes mellitus , hypertension , and glomerulonephritis. If the cause is unknown, it is called idiopathic. Diagnosis of CKD is largely based on history , examination and urine dipstick combined with the measurement of the serum creatinine level see above.

One diagnostic clue that helps differentiate CKD from AKI is a gradual rise in serum creatinine over several months or years as opposed to a sudden increase in the serum creatinine several days to weeks. In many people with CKD, previous kidney disease or other underlying diseases are already known. A significant number present with CKD of unknown cause.

Screening those who have neither symptoms nor risk factors for CKD is not recommended. Screening should include calculation of the estimated GFR eGFR from the serum creatinine level, and measurement of urine albumin-to-creatinine ratio ACR in a first-morning urine specimen this reflects the amount of a protein called albumin in the urine , as well as a urine dipstick screen for hematuria.

It reflects one aspect of kidney function: how efficiently the glomeruli - the filtering units - work.

The units of creatinine vary from country to country. This can be done by combining the GFR level with the clinical assessment of the person, including fluid status, and measuring the levels of hemoglobin, potassium, phosphate and parathyroid hormone PTH. Kidney ultrasonography is useful for diagnostic and prognostic purposes in chronic kidney disease.

Whether the underlying pathologic change is glomerular sclerosis, tubular atrophy, interstitial fibrosis or inflammation, the result is often increased echogenicity of the cortex. The echogenicity of the kidney should be related to the echogenicity of either the liver or the spleen Figure 22 and Figure Moreover, decreased kidney size and cortical thinning are also often seen and especially when disease progresses Figure 24 and Figure However, kidney size correlates to height, and short persons tend to have small kidneys; thus, kidney size as the only parameter is not reliable.

Chronic renal disease caused by glomerulonephritis with increased echogenicity and reduced cortical thickness. Nephrotic syndrome. Hyperechoic kidney without demarcation of cortex and medulla. Chronic pyelonephritis with reduced kidney size and focal cortical thinning.

End-stage chronic kidney disease with increased echogenicity, homogenous architecture without visible differentiation between parenchyma and renal sinus and reduced kidney size. Additional tests may include nuclear medicine MAG3 scan to confirm blood flow and establish the differential function between the two kidneys.

Protein in the urine is regarded as an independent marker for worsening of kidney function and cardiovascular disease. Hence, British guidelines append the letter "P" to the stage of chronic kidney disease if protein loss is significant.

The term "non-dialysis-dependent chronic kidney disease" NDD-CKD is a designation used to encompass the status of those persons with an established CKD who do not yet require the life-supporting treatments for kidney failure known as kidney replacement therapy RRT, including maintenance dialysis or kidney transplantation. The condition of individuals with CKD, who require either of the two types of kidney replacement therapy dialysis or transplant , is referred to as the end-stage kidney disease ESKD.

Apart from controlling other risk factors, the goal of therapy is to slow down or halt the progression of CKD. Control of blood pressure and treatment of the original disease are the broad principles of management. Angiotensin converting enzyme inhibitors ACEIs or angiotensin II receptor antagonists ARBs are recommended as first-line agents since they have been found to slow the decline of kidney function, relative to a more rapid decline in those not on one of these agents.

Guidelines for referral to a nephrologist vary between countries. It may also be useful at an earlier stage e. Other benefits of early nephrology referral include proper education regarding options for kidney replacement therapy as well as pre-emptive transplantation, and timely workup and placement of an arteriovenous fistula in those people with chronic kidney disease opting for future hemodialysis. At stage 5 CKD, kidney replacement therapy is usually required, in the form of either dialysis or a kidney transplant.

In CKD numerous uremic toxins accumulate in the blood. Even when ESKD largely synonymous with CKD5 is treated with dialysis, the toxin levels do not go back to normal as dialysis is not that efficient. If it does, the creatinine level is often normal. The toxins show various cytotoxic activities in the serum and have different molecular weights, and some of them are bound to other proteins, primarily to albumin. Uremic toxins are classified into three groups as small water-soluble solutes, middle molecular-weight solutes, and protein-bound solutes.

Middle molecular weight molecules are removed more effectively with hemodialysis using a high-flux membrane, hemodiafiltration and hemofiltration. However, conventional dialysis treatment is limited in its ability to remove protein-bound uremic toxins. CKD increases the risk of cardiovascular disease, and people with CKD often have other risk factors for heart disease, such as high blood lipids.

The most common cause of death in people with CKD is cardiovascular disease rather than kidney failure. Chronic kidney disease results in worse all-cause mortality the overall death rate which increases as kidney function decreases. While kidney replacement therapies can maintain people indefinitely and prolong life, the quality of life is negatively affected. Transplantation aside, high-intensity home hemodialysis appears to be associated with improved survival and a greater quality of life, when compared to the conventional three-times-a-week hemodialysis and peritoneal dialysis.

People with ESKD are at increased overall risk for cancer. About one in ten people have chronic kidney disease. In Canada 1. Chronic kidney disease was the cause of , deaths globally in , up from , deaths in The cause of chronic kidney disease is in some cases not known; it is referred to as chronic kidney disease of unknown aetiology CKDu.

As of [update] a rapidly progressive chronic kidney disease, unexplained by diabetes and hypertension, had increased dramatically in prevalence over a few decades in several regions in Central America and Mexico, a CKDu referred to as the Mesoamerican nephropathy MeN.

It was estimated in that at least 20, men had died prematurely, some in their 20s and 30s; a figure of 40, per year was estimated in In some affected areas CKD mortality was five times the national rate. MeN primarily affects men working as sugarcane labourers. Although CKDu was first documented among sugar cane workers in Costa Rica in the s, it may well have affected plantation labourers since the introduction of sugar cane farming to the Caribbean in the s.

In colonial times the death records of slaves on sugar plantations was much higher than for slaves forced into other labour. Africans are at greater risk due to the number of people affected with hypertension among them. Administration of antihypertensive drugs generally halts disease progression in white populations but has little effect in slowing kidney disease among black people, and additional treatment such as bicarbonate therapy is often required.

The International Society of Nephrology is an international body representing specialists in kidney diseases. The Renal Association represents Kidney physicians and works closely with the National Service Framework for kidney disease.

The incidence rate of CKD in dogs was The mortality rate of CKD was 9. The Swedish elkhound, Siberian husky and Finnish spitz were the breeds with the lowest rates. Currently, several compounds are in development for the treatment of CKD. These include the angiotensin receptor blocker ARB olmesartan medoxomil ; and sulodexide , a mixture of low molecular weight heparin and dermatan sulfate. Unbiased research with complete reporting is required to determine the safety and effectiveness of acupuncture to treat depression , pain, sleep problems , and uraemic pruritus in people who are undergoing dialysis treatments on a regular basis.
