Hastaların yaş ortalaması 54.8 ± 18.4 (18-92) yıl, kadın/erkek oranı 1.11 idi. En sık nodal başlangıç baş-boyun bölgesinde (%45.9), en sık ekstranodal başlangıç ise gastrointestinal sistem bölgesinde (%9.7) idi. En sık klinik Evre IV (%59.4) olup, onu Evre III (%33.8) takip etti. Histolojik subtiplendirmede en sık orta dereceli histolojiler (%39.1) görülürken, düşük dereceli histolojiler (%35.3) onu takip etti. B semptomları hastaların %63.2'sinde görüldü. Primer tedavi seçeneği olarak hastaların %78.2'sine sistemik kemoterapi uygulanırken, %21.8'ine cerrahi ile birlikte sistemik kemoterapi uygulandığı belirlendi. Beş yıllık yaşam süresi 115 hastada %38 olarak bulundu. Teşhis esnasında hastalığın evresinin yaşam süresi için önemli bir prognostik faktör olduğu görüldü.

In this study, we aimed to investigate the existence of coronary artery disease in dialysis patients who were aCL positive and undergoing hemodialysis and peritoneal dialysis due to end stage renal failure and also to determine its relationship with risk factors in patients with coronary artery disease. This study has been conducted in the end stage renal failure in 140 hemodialysis patients, 18 peritoneal dialysis patients, and 38 healthy controls. The urea, creatinine, total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride, total protein, and albumin values are obtained. In all cases, aCL levels are investigated with ELISA method. In the HD and CAPD patients, no significant relationship could be found between the age, gender, dialysis time, total cholesterol, HDL cholesterol, LDL cholesterol, total protein, and albumin values (p > 0.05). HD and CAPD vs. controls (aCL), 9.2% (13/140), 11.1% (2/18) vs. 2.6% (1/38), p = 0.002. No significant difference was noted between aCL-positive and -negative patients in serum urea, creatinine, total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride, total protein, and albumin levels. The coronary artery disease was determined in three patients out of 16 patients with aCL positivity. The prevalence of aCL antibodies positivity in our study was similar to the prevalence of aCL positivity in other studies. Therefore, we do not think aCL antibodies positivity is a risk factor for coronary artery disease.

Mammalian target of rapamycin (mTOR) group consisting of 37 patients were converted from calcineurin inhibitors (CNI), and the control group included 46 patients (initially CNI-receiving patients). As a control-match of each mTOR inhibitor patient, the succeeding patient with transplantation who continued CNI therapy was chosen. All patients received CNI, MMF, and prednisolone as an immunosuppressive therapy initially. In comparison of two groups, there was no significant difference between sex, donor organ source, donor organ ischemia time, or mismatches. However, mean age between groups was significantly different (mTOR group: 48.3 ± 12, CNI group: 38.6 ± 11, p < 0.001). Decision of conversion to mTOR inhibitors in 30 patients was made by biopsy. The reasons for conversion were determined as CNI nephrotoxicity in 15 patients, chronic allograft nephropathy in 15 patients, malignancy in 6 patients, and renal artery stenosis in 1 patient. Basal glomerular filtration rates (GFRs) were markedly lower in mTOR group than in CNI group (38.8 mL/min vs. 72.7 mL/min). At the end of 48-month follow-ups, GFR increased from 38 mL/min to 54 mL/min in mTOR group; however, it decreased to 53 mL/min from 72 mL/min in CNI group. There was no difference left between the two groups in GFR after 4-year follow-up. Hyperlipidemia was higher in mTOR group. Acute rejection rates were similar. Cytomegalovirus (CMV) disease was more prevalent in CNI group. Graft failure developed due to secondary reasons, causing mortality in both groups. We suggest that conversion to mTOR inhibitors maintains and improves graft functions well.

In relation to the insertion methods, various mechanical and infectious complications may arise. In this study, we aimed to compare early complications of the laparoscopic tunneling method of CAPD placement that we developed recently in order to minimize the complications, with those of the conventional percutaneous method. Included in this study were 12 consecutive patients with ESRD to whom we introduced catheters for CAPD by way of laparoscopic tunneling between April 2003 and July 2003 and followed up for at least 6 months, and 30 patients to whom the catheters were placed percutaneously in the same time period with the same follow-up time. The complications seen during the first 6 months after catheter placement with these two different methods were compared. In all of the subjects, dialysis was started soon after catheter placement. No peroperative morbidity was seen in any of the patients. While with laparoscopic tunneling method no mechanical problem was seen, the percutaneous method resulted in early leakage in 10%, pericatheter bleeding in 3.3%, and hernia in 3.3% of the patients. As infectious complications, peritonitis occurred as one episode/36 patient-months in laparoscopic tunneling and one episode/22.5 patient-months in percutaneous method; catheter insertion site infection was seen in none in the laparoscopic method, while one episode/90patient-months was seen with the percutaneous method. Tunnel infection did not arise in any of the subjects. The authors of this study think that the peritoneal tunneling method for introducing CAPD, which has been recently developed and began to be routinely used by them, is rather safe in terms of early complications.

H. pylori has been shown to be associated with peptic ulcer and gastric cancer development. Moreover, it is held responsible for some other nongastric diseases. Among them, coronary heart disease attracts much debate. Many studies have demonstrated a close relationship between insulin resistance and atherosclerosis. Chronic inflammation and alterations in counter-regulatory hormones are deemed responsible for the etiology of insulin resistance. We aimed to examine the effect of H. pylori on insulin resistance. Sixty-three patients were enrolled in the study. Patients were divided into two groups according to H. pylori presence. HOMA-IR (homeostasis model assessment of insulin resistance) level was used to assess insülin resistance. Thirty-six patients were H. pylori positive and 27 were H. pylori negative. There was no difference between the two groups with regard to age, gender, or body mass index. HOMA-IR level was 1.73 ± 1.1 in the H. pylori-negative group, whereas it was 2.56 ± 1.54 in the H. pylori-positive group (P < 0.05). This study provides the first direct evidence for an association between chronic H. pylori infection and insulin resistance.
