Background and aim: Immunoglobulin A nephropathy (IgAN) is the most frequent glomerular disease worldwide and one of the main causes of chronic kidney disease. We aimed to investigate clinicopathological correlations in IgAN patients by gender.
Materials and methods: The study was based on a retrospective analysis of renal biopsy data and clinical manifestations of the disease. Consecutive 73 biopsy-proven IgAN cases of male (62%) and female (38%) patients were investigated. Renal biopsies were reviewed using the new Oxford classification assessing the MEST (mesangial hypercellularity, endocapillary hypercellularity, segmental sclerosis/adhesion, tubular atrophy/interstitial fibrosis) score. The most powerful IgAN prognostic risk factors, morphological (segmental glomerulosclerosis and tubular atrophy/interstitial fibrosis) as well as clinical (proteinuria and hypertension) were taken into account in the correlation analysis. The mean rate of renal function decline was expressed as a slope of eGFR during the follow-up (FU) dividing delta GFR with the FU years.
Results: The mean age of the patients was 33.7 years (range, 16–76). Follow-up data were available for 64 patients with the mean follow-up of 4.1 years. The mean proteinuria at biopsy was 0.79 g/24 h. The mean arterial pressure (MAP) was 94.5 ± 16.7 mmHg and 7% of the patients were hypertensive. The initial mean estimated glomerular filtration rate (eGFR) was 94.9 ± 30.7 mL/min, at the end of the follow-up it was 86.2 ± 27.1 mL/min. The mean rate of renal function decline was −3.4 ± 11.9 mL/min/1.73 m² per year in males (P < 0.05) and −0.7 ± 5.3 mL/min/1.73 m² per year in females. The Spearman correlation analysis confirmed a higher MEST score in the whole cohort and in males correlated with disease progression. In patients with proteinuria below 1.0 g/24 h, disease progression was faster in males.
Conclusions: According to the correlation analysis of the main prognostic risk factors, affecting the progression of IgAN, we can conclude that IgA nephropathy in males progresses more rapidly compared to females. Full article

Cell proliferation and apoptosis in the remnant rat kidney after treatment with lowdose irradiation was investigated.
Material and methods. In the first group (n=9), adult male Wistar rats underwent 5/6 nephrectomy (NPX); in the second group (n=9), NPX was combined with low-dose irradiation. Rats without surgery and irradiation formed the control group (n=9).
Results. Hypertension and proteinuria induced by NPX were decreased by 3-Gy irradiation. The 5/6 NPX rats showed a dramatic increase in proliferating and apoptotic cells in the glomeruli and in the distal tubules at week 2, which was significantly decreased by low-dose irradiation.
Conclusion. The data demonstrate that low-dose irradiation is a factor slowing the process of chronic renal injury. Full article

New system and nomenclature of diets for Estonian health care institutions have been developed in the university hospital based on theoretical and practical experience obtained over several years of cooperation with medical scientists from different fields of specialization. The nomenclature of diets includes ordinary food and eight groups of diet food with subgroups. The normative values of the basic nutrients are in accordance with the Estonian and Nordic nutritional recommendations. The whole system includes the menus and recipes of nutritional food portions. The system of treatment diets helps to optimize proper nutrition in different departments and organize better patient care. Full article
