Neonatal proteinuria

Introduction In general, proteinuria in infants (under one year old) and children (from one year old to ten years old) is defined as daily urinary protein excretion greater than 110 mg/m2 and 85 mg/m2, respectively, and neonates (within 30 days) are greater than 145 mg/m2 is considered to have proteinuria. Most of the lactating mothers can enter the baby through the milk. If the concentration of the drug in the milk is too high, the side effects of the drug will affect and harm the baby's health. Kanamycin can cause infant poisoning, tinnitus, hearing loss and proteinuria. Wait. The cause of proteinuria is closely related to the barrier function of glomeruli.

The method of test paper analysis: the method most commonly used to determine urine protein. It appears yellow in the presence of anuria-free protein, and the protein in the urine interferes with the binding of the dye to the slow storage liquid, turning the yellow color to green. It is best to have morning urine, the morning urine is the strongest, and the orthostatic proteinuria can be ruled out. Qualitative examination is only a screening test, not as an accurate indicator of urine protein content.

Differential diagnosis

Intermittent proteinuria: refers to the urine protein quantitation exceeds normal levels, but not every urine test is abnormal. Intermittent proteinuria is more common in adolescents with faster growth and development, usually with less stable circulatory system, such as orthostatic hypotension and fingertips.

Transient urine protein: Temporary or transient urine protein refers to normal kidney, but transient urine protein occurs during fever, heart failure or dehydration. After exercise, there may be an increase in temporary urinary protein excretion, especially after adolescent long-distance running, swimming, football, basketball and other sports, the protein in the urine is transiently increased.

Milky white urine: also known as chyluria, it is milky white like milk. This is due to the inability to absorb sputum from the intestines, causing the chyle to flow back into the urine. Causing urinary fistula has congenital factors, such as congenital lymphatic valve dysfunction; there are also secondary factors, such as common filariasis and urinary system purulent infection.

Persistent urinary protein: persistent urinary protein is mostly pathological urinary protein, which means that urinary protein is not affected by receptor level, and urine protein is positive for multiple times. urinary protein quantification and composition analysis should be carried out, and further differentiated by clinical.
