Abstract

Introduction: Primary hyperoxaluria type 1 (PH1) is a rare and inherited condition of urolithiasis. The aim of our study was to analyze clinical, paraclinical, and evolutionary aspects of PH1 in adult patients in our Nephrology department.

Methods: We conducted a retrospective single-center study between 1990 and 2021. We collected patients followed for PH1 confirmed by genetic study and/or histopathological features of renal biopsy and morphoconstitutional analysis of the calculi.

Results: There were 25 patients with a gender ratio of 1.78. The median age at onset of symptoms was 18 years. A delay in diagnosis more than 10 years was noted in 13 cases. The genetic study found the I244T mutation in 17 cases and 33-34 InsC in 4 cases. A kidney biopsy was performed in 5 cases, on a native kidney in 4 cases and on a graft biopsy in one case. The analysis of calculi was done in 10 cases showing type Ic in 2 cases. After a median follow-up of 13 years (1 year-42 years), 14 patients progressed to end-stage chronic renal failure (ESRD). The univariate study demonstrated a remarkable association with progression to ESRD in our population (44% vs. 56%) RR = 13.32 (adjusted ORs (95% CI): 2.82-62.79) (p < 0.01).

Conclusion: Progression to ESRD was frequent in our series. Early diagnosis and adequate management can delay such an evolution.

原发性高草酸尿1型:成人的临床、临床旁和进化方面
原发性高草酸尿1型(PH1)是一种罕见的遗传性尿石症。我们研究的目的是分析我们肾脏病科成年患者PH1的临床、临床旁和进化方面。方法:我们在1990年至2021年间进行了一项回顾性单中心研究。我们收集了经遗传研究和/或肾活检组织病理学特征和结石形态结构分析证实的PH1患者。结果:25例患者,性别比为1.78。出现症状的中位年龄为18岁。13例延误诊断超过10年。遗传研究发现17例患者有I244T突变,4例患者有33-34 InsC突变。5例进行了肾活检,4例进行了原生肾活检,1例进行了移植肾活检。结石分析10例,2例为Ic型。中位随访13年(1 -42年)后,14例患者进展为终末期慢性肾功能衰竭(ESRD)。单因素研究显示,在我们的人群中,与ESRD进展有显著关联(44% vs. 56%) RR = 13.32(调整后的or (95% CI): 2.82-62.79) (p < 0.01)。结论:在我们的研究中,进展为ESRD是很常见的。早期诊断和适当的管理可以延缓这种演变。
