Acute nephritis easily confused with the diseases

Early acute nephritis easily confused with the following diseases, should draw attention. (1) fever proteinuria can occur at any febrile illness. During the heat can be detected in urine protein and type, but very few red blood cells, no edema and hypertension. Heat Forward, urine abnormal rapid recovery. (2) any abnormal urinary infection caused by infections such as bacteria, viruses, particularly hepatitis B hemolytic streptococcus infection, about 1 / 3 of patients, there will be mild microscopic hematuria, a small amount of urine protein and the type, but no edema and hypertension, when infection control, urine inspection is back to normal. (3) focal glomerulonephritis generally occurs during infection (acute nephritis occurred in about two weeks after infection); focal nephritis with hematuria and proteinuria very light; cure infection, check urine of patients to return to normal, good prognosis. And the only light acute nephritis urine changes, but no edema and hypertension similar. (4) Movement abnormal urine after strenuous exercise (such as long-distance running, swimming, a quick march……) or over exertion, in the urine within a few hours there can be unusual - hematuria, proteinuria and type urine, but the rest 1-2 days (by less than 7 days) is back to normal. In the event of abnormal urine at the same time without edema and hypertension (individual may have temporarily hypertension). (5) lupus nephritis systemic lupus erythematosus caused kidney damage, and sometimes similar performance acute nephritis, accompanied rashes, hair loss, photosensitivity, joint pain and heart, liver, lung, brain and other organs of lesions, and there are fever, leukopenia, laboratory SM antibodies or anti-DNA antibodies and anti-nuclear antibody positive. (6) toxemia of pregnancy occurs late in pregnancy, patients edema, hypertension, proteinuria and possession of urine, can be serious in hypertensive encephalopathy, especially in the last month of pregnancy when the more obvious symptoms. However, the lack of hematuria is the main feature, and most of normal renal function, fundus that retinal artery spasm, bleeding, leakage and other changes, and after the vast majority of patients to return to normal. (7) primary nephrotic syndrome of acute nephritis with nephrotic syndrome and nephrosis are easily confused. The latter proteinuria (≥ 3.5 g / day) and hypoproteinemia features without hematuria, the former hematuria, no more than hypoproteinemia, differential points for kidney inspection, the former diffuse capillaries proliferative glomerulonephritis, which can be a minor disease or other chronic pathological changes in glomerular damage. (8) acute renal pelvis nephritis acute nephritis occurred if the urethra, bladder mucosa and kidney congestion and edema can cause bladder stimulation symptoms similar acute pyelonephritis. But pyelonephritis fever, hematuria, interleukin are more positive urine culture, effective antibiotic treatment, and no significant edema, hypertension, and other performance, nor red blood cells in urine tube. Shang Yi acute pyelonephritis and chronic nephritis acute confusion.
