RESUMO
BACKGROUND: Alport syndrome (AS) is an inherited disease of the glomerular basement membrane caused by mutations in genes encoding α3, α4, or α5 chains of type IV collagen. It manifests with hematuria or proteinuria, which is often accompanied by hearing impairments and ocular abnormalities. Histopathologically, AS shows mesangial proliferation and sometimes incidental immunoglobulin A (IgA) deposition. Hematuria or proteinuria is also a common presentation in patients with IgA nephropathy that makes it difficult to differentially diagnose AS and IgA nephropathy solely based on these clinical and pathological features. CASE SUMMARY: Herein, we present the case of a 59-year-old female patient who was admitted to our hospital with persistent microscopic hematuria and occasional proteinuria that had lasted for > 2 years. This patient had a familial history of renal disease and was diagnosed with autosomal dominant AS (ADAS) and IgA nephropathy based on the findings of renal biopsy as well as genetic testing performed using whole-exome sequencing, which suggested that the patient carried a novel heterozygous variation (c.888G>A:p.Gln296Gln) in the COL4A3 gene that enriches the mutation spectrum of ADAS. The proband received an angiotensin receptor blocker therapy after a definitive diagnosis was established. After one year of therapy, a significant reduction in proteinuria was observed. The number of microscopic red blood cells per high-power field decreased to one-quarter of the baseline levels. Renal function also maintained well during the follow-up. CONCLUSION: Our case highlights the significance of performing kidney biopsy and genetic testing in the diagnosis of AS and familial IgA nephropathy.
RESUMO
OBJECTIVE: To observe the effect of TCM therapy for detoxification, removing stasis, and nourishing yin on corticosteroid-induced hyperlipemia in patients with systemic lupus erythematosus (SLE), and to investigate its mechanism. METHODS: One hundred and seventy patients with SLE were randomly assigned to the integrative medicine group (IM group) and the Western medicine group (WM group), 85 in each group. Also, 30 healthy subjects selected from blood donors were enrolled in the normal control (NC) group. All patients were treated mainly with prednisone, while those in the IM group were given TCM therapy additionally, and the therapeutic course for both groups was 6 successive months. The changes of serum total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C) and apolipoprotein A (ApoA) were determined and observed. A 2-year follow-up study was carried out in 16 patients of the WM group and 25 of the IM group. RESULTS: Before treatment, no significant difference had been found among the three groups in the serum levels of lipids and lipoproteins. After the 6-month treatment, as compared with the WM group, the IM group showed lower levels of TC, TG, LDL-C, and VLDL-C (P<0.05 or P<0.01) and higher levels of HDL-C and ApoA (P<0.05). A similar effect was also shown by the follow-up study in the IM group (P<0.05 or P<0.01). CONCLUSION: TCM therapy for detoxification, removing stasis, and nourishing yin can effectively regulate the levels of serum lipids and lipoproteins in preventing and treating SLE patients with corticosteroid-induced hyperlipemia.
