Background: Although several renal biopsy registry reports have been published worldwide, there are no data on primary glomerular disease trends in Turkey. Methods: Three thousand eight-hundred fifty-eight native kidney biopsy records were assessed in the Turkish Society of Nephrology Primary Glomerulopathy Working Group (TSN-GOLD) Registry. Secondary disease and transplant biopsies were not recorded in the registry. These records were divided into four periods, before 2009, 2009 to 2013, 2013–2017, and 2017–current. Results: A total of 3858 patients (43.6% female, 6.8% elderly) were examined. Nephrotic syndrome was the most common biopsy indication in all periods (58.6%, 53%, 44.1%, 51.6%, respectively). In the whole cohort, IgA nephropathy (IgAN) (25.7%) was the most common PGN with male predominance (62.7%), and IgAN frequency steadily increased through the periods (× 2 = 198, p < 0.001). MGN was the most common nephropathy in the elderly (> 65 years), and there was no trend in this age group. An increasing trend was seen in the frequency of overweight patients (× 2 = 37, p < 0.0001). Although the biopsy rate performed with interventional radiology gradually increased, the mean glomeruli count in the samples did not change over the periods. Conclusions: In Turkey, IgAN is the most common primary glomerulonephritis, and the frequency of this is increasing. © 2022, The Author(s), under exclusive licence to Springer Nature B.V.

Makale, WOS:000925209300014, xtrarenal involvement occurs in approximately 20% of patients with complement-mediated hemolytic-uremic syndrome. The involvement is usually of the nervous system, and cardiac involvement occurs in 3%-10% of patients. Cardiac manifestations vary, including myocardial infarction, cardiomyopathy, and acute decompensated heart failure. Among these patients, thrombotic microangiopathy-related cardiac dysfunction is mainly due to the continuous activation of the complement system, which leads to endothelial damage and thrombosis in the coronary microvessels. We wanted to highlight the importance of cardiac evaluation at the time of diagnosis or during follow-up in thrombotic micro-angiopathy patients by presenting a case of heart failure with low ejection fraction in a 24-year-old young patient in whom we detected complement-mediated hemolytic-uremic syndrome, a secondary mutation of complement factor H receptor. It is still an unknown issue because of the rarity of cardiac involvement in complement-mediated hemolytic-uremic syndrome patients. Primary myocardial involvement is increasingly recognized as a possible concomitant feature of hemolytic-uremic syndrome. Failure to perform a detailed cardiac evaluation both at diagnosis and during follow-up in complement-mediated hemolytic-uremic syndrome patients can lead to fatal outcomes. Anti-complement therapy can also lead to good cardiac outcomes in these patients.

AMAÇ: Hemodiyaliz hastalarında kronik bir metabolik asidoz eğilimi söz konusudur. Yüksek olgu sayılı çalışmalarda diyaliz öncesi serum bikarbonat konsantrasyonu ile mortalite arasında ilişki saptanmıştır. Çalışmamızda 32 ve 36 mmol/L bikarbonat içerikli diyaliz solüsyonu kullanımının asidoz kontrolüne etkisi araştırıldı.GErEÇ ve YÖnTEMLEr: Bir merkezde haftada üç kez hemodiyalize giren 91 (43E,48K) hastaya ilk altı ay 32 mmol/L diyalizat, ikinci altı ayda aynı hastalara 36 mmol/L bikarbonat diyalizat kullanılmaya başlandı ve diyaliz öncesi ve sonrası plazma bikarbonat düzeyleri karşılaştırıldı. BULGULAr: İlk altı ayda ortalama bikarbonat düzeyi 20,552,55 mmol/L olup sadece 30 hastada bikarbonat düzeyi 22 mmol/L ve üzerindeydi. İkinci altı aylık dönemde ise ortalama bikarbonat düzeyi 23,593,3 mmol/L olup hedef düzeylerdeydi. Ancak 19 hastada diyaliz sonu ortalama bikarbonat düzeyi 30 mmol/L'nin üzerinde bulundu. Prediyaliz asidozu olan hastaların ortalama interdiyalitik kilo artışı 2,80,5 kg olup, asidozu olmayan gruptan daha yüksekti (p0,05). Prediyaliz üre, Kt/V, albumin, potasyum ve CRP düzeyleri bakımından iki periyot arasında anlamlı farklılık yoktu. SOnUÇ: 36 mmol/L bikarbonat içeren diyaliz solüsyonu kullanımı ile asidoz kontrolü daha iyi yapılmakta ancak hastaların yaklaşık yüzde yirmisinde diyaliz sonunda ciddi metabolik alkaloz gelişmektedir. Bu durum aritmiyi tetikleyebilir. Bu nedenle aritmisi olan veya metabolik alkaloza eğilimi olan hastalarda yüksek bikarbonatlı solüsyon kullanımında bikarbonat içeriğinin ayarlanmasının gerektiğini düşünmekteyiz., OBJECTIVE: In hemodialysis patients; there is a continuing tendency to metabolic acidosis. In studies, the relationship between serum bicarbonate concentration and dialysis mortality has been determined. In our study, the effect of 32 and 36 mmol/L bicarbonate-containing dialysis solution on acidosis control was investigated. MATErıAL and METHODS: In a hemodialysis clinic, a 32 mmol/L bicarbonate-containing dialysate was used in the first six months and a 36 mmol/L bicarbonate-containing dialysate was used in the second six months. The study was performed on 91 (43M/48F) patients. Plasma bicarbonate levels before and after dialysis were compared. rESULTS: In the first period, only 30 patients' bicarbonate levels were 22 mmol/L or more. In the second period, the mean bicarbonate level was 23.59±3.3 mmol/L. However, the level of bicarbonate after dialysis was above 30 mmol/L in 19 patients. In patients with predialysis acidosis, the interdialytic mean weight gain was higher than in the group without acidosis (p>0.05). There were no significant differences between the two periods in terms of predialysis urea, Kt/V, albumin, potassium and CRP levels.CONClUSION: Acidosis control is better with the use of a dialysis solution containing 36 mmol/L bicarbonate. But at the end of dialysis, severe metabolic alkalosis developed on approximately twenty percent of patients. This situation can trigger arrhythmia. We therefore think that it is necessary to adjust the machine bicarbonate in the use of high bicarbonate solution in patients with arrhythmia or alkalosis tendency.

WOS:000370271100029, PubMed ID: 27511507, Background/aim: The aim of this study is to establish follow-up protocols for adult patients with common variable immunodeficiency (CVID) in a recently founded adult immunology clinic in the Central Anatolia Region of Turkey, where a clinical immunology center for adults was not available previously. Materials and methods: A total of 25 patients with CVID aged 18 years and older were included in this study. The file format consisted of 13 pages and was developed for the purpose of the study. Separate sections were designated for identity information, medical history, disease course, previous and current laboratory and imaging studies, follow-up plans, detection and management of complications/ comorbidities, and treatment results. Results: The mean age of the patients was 36.6 ± 13.4 years. The delay in diagnosis was 107 ± 95.6 months. In 92% of patients, initial symptoms resulting in admission to healthcare facilities were infections. Seventeen of 25 patients (68%) had bronchiectasis at the beginning of follow-up. Conclusion: Early identification of complications and comorbidities in patients with CVID will significantly improve quality of life and survival. Close observation and standardized protocols for follow-up are essential components of management.
