Successful treatment of nephrotic syndrome due to pregnancy-related crescentic IgA nephropathy: a case report. BMC Nephrol 2023; 24:92. [PMID: 37038123 PMCID: PMC10084611 DOI: 10.1186/s12882-023-03152-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Accepted: 04/03/2023] [Indexed: 04/12/2023] Open
Abstract
BACKGROUND Crescentic immunoglobulin A (IgA) nephropathy, defined as > 50% of the glomeruli with crescents, often has a poor renal prognosis. Because of the high prevalence of pre-eclampsia in the second trimester of pregnancy, we often fail to investigate the new onset of glomerulonephritis and the aggravation of subclinical nephropathies. We report a case of nephrotic syndrome suggestive of crescentic IgA nephropathy possibly triggered by pregnancy. CASE PRESENTATION A 33-year-old multipara was referred for persistent proteinuria, hematuria, and hypoalbuminemia two months postpartum. The patient was diagnosed with proteinuria for the first time at 36 weeks of gestation. The patient was normotensive during pregnancy. Renal biopsy revealed crescentic IgA nephropathy, with cellular crescents in 80% of the glomeruli and no global sclerosis. After treatment with pulse steroids followed by high-dose oral glucocorticoids and tonsillectomy, a gradual improvement was seen in proteinuria, hematuria, and hypoalbuminemia. CONCLUSION Although the precise mechanism remains unclear, pregnancy possibly triggered the new onset of crescentic IgA nephropathy or the aggravation of subclinical IgA nephropathy.

Abstract
OBJECTIVE Understanding the long-term prognosis of preeclampsia (PE) is important. Proteinuria and poor renal function persist in some PE patients, but the relationship between their histopathological findings of kidney and renal prognosis is unknown. Our objective was to clarify the relationship between clinicopathological features and renal prognosis in PE patients. STUDY DESIGN Retrospective observational study. MAIN OUTCOME MEASURES Seventy patients who had been referred to the Niigata University Hospital between 1977 and 2014 and were diagnosed with PE were classified into unimproved and improved groups. The unimproved group included patients whose serum creatinine level had doubled and/or whose proteinuria had persisted until the end of observation, which included three patients with end-stage kidney disease (ESKD). The improved group included patients whose serum creatinine level did not double and whose proteinuria had disappeared until the last observation. We examined and compared these patients' characteristics, clinical and laboratory findings, and renal histopathological findings from percutaneous kidney biopsies. RESULTS There were no significant differences in the clinical backgrounds and clinical findings between the two groups during pregnancy. However, light microscopy findings of their kidney biopsies were able to identify significantly more severe duplications of the capillary loop, interstitial cell infiltration, and interstitial fibrosis in the unimproved group. CONCLUSIONS Histopathological examination of the kidney may be a valid method for predicting the long-term prognosis of renal function and for histological a risk assessment of poor renal recovery in PE patients.

Acute Kidney Injury in Pregnancy: The Need for Higher Awareness. A Pragmatic Review Focused on What Could Be Improved in the Prevention and Care of Pregnancy-Related AKI, in the Year Dedicated to Women and Kidney Diseases. J Clin Med 2018; 7:jcm7100318. [PMID: 30275392 PMCID: PMC6210235 DOI: 10.3390/jcm7100318] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2018] [Revised: 09/18/2018] [Accepted: 09/19/2018] [Indexed: 12/14/2022] Open
Abstract
Pregnancy-related acute kidney injury (pAKI), preeclampsia (PE), and the hypertensive disorders of pregnancy are closely related conditions, which are, in turn, frequently linked to pre-existing and often non-diagnosed chronic kidney disease (CKD). The current literature and research mainly underline the effects of pregnancy complications on the offspring; this review strongly emphasizes the maternal health as well. These conditions not only negatively affect pregnancy outcomes, but have a relevant effect on the future health of affected mothers and their children. Therefore, dedicated diagnostic and follow-up programs are needed, for optimizing materno-foetal health and reducing the impact of pregnancy-related problems in the mothers and in the new generations. This narrative review, performed on the occasion of the 2018 World Kidney Day dedicated to women’s health, focuses on three aspects of the problem. Firstly, the risk of AKI in the hypertensive disorders of pregnancy (the risk is the highest in developing countries; however PE is the main cause of pregnancy related AKI worldwide). Secondly, the effect of AKI and the hypertensive disorders of pregnancy on the development of CKD in the mother and offspring: long-term risks are increased; the entity and the trajectories are still unknown. Thirdly, the role of CKD in the pathogenesis of AKI and the hypertensive disorders of pregnancy: CKD is a major risk factor and the most important element in the differential diagnosis; pregnancy is a precious occasion for early diagnosis of CKD. Higher awareness on the importance of AKI in pregnancy is needed to improve short and long term outcomes in mothers and children.

Abstract
We analyzed diurnal hemodynamic parameters (HR, systolic BP, and diastolic BP) recorded from two groups of edematous and preeclamptic pregnant women. The unidirectional character of changes in the control over the functional state of cardiovascular system was revealed except for the indices, which mark a pathological process: elevated diurnal BP in preeclampsia and diminished percentage of oscillation power in edematous patients. Uniformity of the regulatory changes in patients with and without arterial hypertension can be viewed as manifestation of allostasis developed by the cardiovascular system during pregnancy. In preeclampsia, the greater allostatic load was reflected by the changes in diurnal, daytime, and nighttime BP and in the circadian index calculated for HR, systolic BP, and diastolic BP. In edematous patients, elevation of allostatic load was indicated by the percentage of ultradian rhythms.
