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: Periton diyalizi son dönem böbrek yetmezliği hastalarında böbrek yerine koyma tedavisi seçeneklerinden birisidir. Bağlı (konjuge) linoleik asit (KLA), bir omega-6 esansiyel yağ asidi olan linoleik asidin geometrik ve pozisyonel izomerlerini kapsar. Bu çalışmada, sürekli ayaktan periton diyalizi (SAPD) hastalarında ve sağlıklı kişilerde KLA izomerleri içinde biyolojik etkinlik yönünden önemli bulunan plazma 10-trans, 12-cis KLA (t10,c12 KLA) ve 9-cis,11-trans KLA (c9,t11 KLA) düzeylerini ve bu yağ asitleri ile kilo, vücut kitle indeksi (VKİ), C-reaktif protein (CRP), paratiroid hormon (PTH) arasındaki ilişkiyi araştırmayı amaçladık. GEREÇ ve YÖNTEMLER: Çalışma 20-75 yaşları arasında en az 6 ay süre ile diyalize giren 51 (erkek: 21, kadın: 30) SAPD hastası ve 20-60 yaşları arasında 45 (erkek: 25, kadın: 20) sağlıklı kişi üzerinde gerçekleştirildi. Plazma t10,c12 KLA ve c9,t11 KLA düzeyleri gaz kromatografi si/kütle spektrofotometresi (GS-MS) yöntemi ile ölçüldü. BULGULAR: SAPD hastalarının plazma t10,c12 KLA ve c9,t11 KLA düzeyleri sırası ile 11.84 ± 5.3 ve 8.34 ± 4.4 mg/L olarak bulundu. Aynı parametreler kontrol grubunda sırası ile 12.88 ± 4.1 ve 9.20 ± 4.5 mg/L olarak bulundu. SAPD hastalarında ve kontrol grubunda KLA izomerlerinin plazma düzeyleri arasında önemli bir fark bulunamadı. SAPD hastalarında plazma t10,c12 KLA ve c9,t11 KLA düzeyleri ile PTH düzeyleri arasında istatistiksel açıdan anlamlı düzeyde olumsuz bir ilişki bulundu. Fakat, SAPD hastalarında plazma KLA izomerleri düzeyleri ile CRP, VKİ ve kilo değerleri arasında anlamlı bir ilişki bulunamadı. SONUÇ: Bulgularımıza dayanarak ikincil hiperparatiroidizmin eşlik ettiği SAPD hastalarında fosfor kontrolünün iyi yapılması kaydıyla KLA’dan zengin bir diyet yüksek parathormon düzeylerini azaltmada yarar sağlayabilir., OBJECTIVE: Peritoneal dialysis is a renal replacement therapy in patients with end stage renal disease. Conjugated linoleic acid (CLA) refers to a class of positional and geometric conjugated isomers of the omega-6 essential fatty acid, linoleic acid. This study aimed to investigate biologically active isomers of CLA (10-trans, 12-cis CLA and -9-cis,11-trans CLA) and the relationship between these fatty acids and weight, body mass index (BMI), C-reactive protein (CRP) and parathyroid hormone (PTH) in continuous ambulatory peritoneal dialysis patients (CAPD) and healthy subjects. MATERIAL and METHODS: This study was performed on 51 (21M, 30F) CAPD patients at least 6 months under dialysis, aged 20-75 years and 45 (25M, 20F) healthy control subjects aged 20-60 years. Plasma 10-trans, 12-cis CLA (t10,c12 CLA) and 9-cis,11-trans CLA (c9,t11 CLA) levels were measured by GS-MS technique. RESULTS: t10,c12 and c9,t11 isomers of CLA levels of the CAPD patients were as follows: 11.84 ± 5.3 and 8.34 ± 4.4 mg/L respectively. The same parameters of the controls were as follows: 12.88 ± 4.1 and 9.20 ± 4.5 mg/L, respectively. The differences between plasma CLA isomers levels of CAPD patients and control subjects were not signifi cant. Isomers of CLA negatively correlated with serum PTH levels in CAPD patients. However, there was no signifi cant correlation between plasma isomers of CLA and weight, BMI, CRP in CAPD patients. CONCLUSION: These fi ndings suggest that a CLA-rich diet may help in reducing high levels of parathyroid hormone in the case of good control of phosphorus in CAPD patients associated with secondary hyperparathyroidism.
