In the occurrence and development of glomerulonephritis, proteinuria is themain manifestation, which is easily recurrent but not easily got rid of in a short period of time. It may remain even after disappearance of the general symptoms. In some patients, there are no symptoms and signs at all in the initial stage, except proteinuria, the only distinct manifestation. Prof. Ye Chuanhui, from Chengdu University of Traditional Chinese Medicine, has accumulated rich experience for treating this disorder, which is introduced in the following.……展开更多

FSGS is a risk factor for endstage renal disease. Objective: To document preeclamptic women with proteinuria that developed eight weeks prior to hypertension with confirmed FSGS postpartum. Case: A 20-year-old nulliparous Japanese woman with a negative dipstick test result at gestational week (GW) 18 exhibited proteinuria 1+ on dipstick test at GW 22. Proteinuria determined from the random urine protein to creatinine ratio (P/Cr, g/g) was increased from 3.7 at GW 26 to 4.6 and 8.9 at GW 28 and 30, respectively. She developed hypertension (142/66 mmHg) at GW 30. Due to increased edema, emergency cesarean section was performed at GW 33. She gave birth to an otherwise healthy female small-for-gestational-age infant, weighing 1290 g. Postpartum course was uneventful except for persisting proteinuria: P/Cr of 9.8 just before delivery decreased to 3.6 and 1.7 on postpartum weeks 9 and 17, respectively. Renal biopsy on postpartum week 13 revealed FSGS in this patient. Conclusion: Hidden FSGS may have manifested as preeclampsia in this patient. This case highlighted the need to determine the prevalence of asymptomatic FSGS among women who later develop preeclampsia.展开更多

Case 1 exhibited a urinary protein concentration of 46 mg/dL in the absence of hypertension, and abdominal pain due to placental abruption with hypertension at gestational week (GW) 29–3/7 and 29–4/7, respectively. Case 2 exhibited a urinary protein/creatinine ratio of 2.67, developed hypertension, required cesarean section, and developed posterior reversible encephalopathy syndrome at GW 28–1/7, 29–6/7, and 32–0/7, and on postpartum day 2, respectively. As women with proteinuria alone are not diagnosed as having preeclampsia and as a diagnosis of gestational proteinuria can be made only at 12 weeks postpartum, a prospective technical term applicable to the condition of proteinuria alone is needed to increase physicians’ attention to this condition.展开更多
