“Besides excretory functions, the most important job of the kidney is to control blood pressure which it does by maintaining salt and water balance in the body. These two things, along with some hormones produced by the kidney, maintain normal blood pressure,” explains Col Madhuri Kanitkar, paediatric
nephrologist and head of the department of Paediatrics at the Armed
Forces Medical College (AFMC).
In case of sustained high blood pressure , the kidneys become susceptible to irreversible damages. Therefore, blood pressure and the kidneys are closely related and either one affects the other, said Kanitkar. “Just as sustained hypertension (HT) can cause damage to the kidney , a damaged kidney can also lead to HT among children. The most common cause of secondary HT in children is acute nephritis,” said paediatrician Jayant Navarange.
Puffiness in the face, intense headaches and vomiting are the usual symptoms. These persist for about a week or two. An obstructed renal artery supplying blood to the kidney also leads to HT among children , he added.
Again, children who are overweight usually have higher blood pressure. Some children inherit the tendency of HT from one or both parents who have high blood pressure. In the absence of a national registry , the exact incidence and burden of kidney diseases among children in India is not known. “In our institution, which has a dedicated paediatric nephrology unit, children with kidney diseases form approximately 8 to 10 per cent of total out patient attendance and 12 per cent of admission to the paediatric ward,” said Kanitkar.
The Indian Society of Paediatric Nephrology recently set up a national registry to help determine the magnitude of the problem in the country.
“But it will take some time to come up with concrete data regarding its incidence,” said Kanitkar. “Children, even infants, can have high blood pressure . The awareness that essential hypertension has its origin in childhood has resulted in increased emphasis on check-ups .
An annual check- up of blood pressure among children above three years old is highly recommended,” said Kanitkar.
“What we need in India today are more trained paediatric nephrologists and paediatric nephrology units. In a situation of limited resources, it
may be more cost effective to direct them towards preventive nephrology,” said Avinash Bhondwe, president of the city chapter of Indian Medical Association (IMA). “Therein lies a greater role for the paediatric nephrologist and paediatrician to detect and treat children at risk for renal failure. This may reduce the burden of young adults requiring dialysis and transplant.”
In case high blood pressure is recorded, the child needs to be investigated for a possible kidney disorder. Simple precautions that can be taken to keep blood pressure in check are:
n weight control
n increased physical
activity
n diet with low
sodium and high
potassium
SYMPTOMS OF KIDNEY DISORDER
n Burning or pain during urination or straining to pass urine n Significant increase in the frequency of urination n Difficulty in controlling urination in children who are mature enough to use the toilet or recurrence of nighttime bed wetting n Blood or protein in the urine n Craving for salt and excessive thirst n Rickets in the older children or pain in bones
