    In this retrospective study with case-control design, we aimed to determine the clinical and pathological characteristics of post-transplant glomerulonephritis (GN), and their effects on transplant recipients.

    Diffuse Cavernous Hemangioma of the Colon
    (2016-07-01T00:00:00Z) Mirioglu, ŞAFAK; ÇAVUŞ, Bilger; Iliaz, Raim; Besisik, Fatih; MİRİOĞLU, ŞAFAK
    A 70-year-old man was admitted to our clinic with a history of rectal bleeding and constipation, his colonoscopy revealed varicosities and bluish nodular lesions of the rectum (Figure 1). Abdominal CT showed multiple nodular lesions beginning from the distal descending colon and extending to the rectum, calcifications suggesting phleboliths were also seen in these lesions. A contrast enhanced pelvic MRI demonstrated multiple tubular lesions showing hyperintensity on T2-weighted images and hypointensity on T1-weighted images, consistent with the affected areas on the CT scan (Figure 2). It was a diffuse cavernous hemangioma, which mostly affects the rectosigmoid colon in the gastrointestinal tract, and can clinically mimic internal hemorrhoids, ulcerative colitis or cancer (1). Gastrointestinal hemangioma is a rare benign vascular neoplasm, and might be associated with a congenital disorder like Osler-Weber-Rendu disease, Maffucci-s syndrome, Klippel-Trenaunay syndrome, or the congenital blue rubber bleb nevus syndrome (2). Even though there are different medical treatment options targeting VEGF and FGF-mediated pathways such as bevacizumab and thalidomide, and endoscopic approaches like sclerotherapy and electrocautery; complete resection of the hemangioma is the only curative treatment method (1, 3). Therefore, the patient was referred to department of surgery for a definitive treatment, and lost to follow-up.

    Co-Deposition of IgM and C3 May Indicate Unfavorable Renal Outcomes in Adult Patients with Primary Focal Segmental Glomerulosclerosis
    (2019-10-01T00:00:00Z) Mirioglu, ŞAFAK; Caliskan, Yasar; Ozluk, Yasemin; DİRİM, Ahmet Burak; Istemihan, Zulal; Akyildiz, Arif; YAZICI, Halil; TÜRKMEN, Aydın; KILIÇASLAN, Işın; SEVER, Mehmet Şükrü; MİRİOĞLU, ŞAFAK
    Background/Aims: We aimed to investigate the effects of glomerular IgM and C3 deposition on outcomes of adult patients with primary focal segmental glomerulosclerosis (FSGS). Methods: In this retrospective analysis, 86 consecutive adult patients with biopsy-proven primary FSGS were stratified into 3 groups according to their histopathological features: IgM- C3-, IgM+ C3-, and IgM+ C3+. Primary outcome was defined as at least a 50% reduction in baseline estimated glomerular filtration rate (eGFR) or development of kidney failure, while complete or partial remission rates were secondary outcomes. Results: Glomerular IgM deposits were found in 44 (51.1%) patients, 22 (25.5%) of which presented with accompanying C3 deposition. Patients in IgM+ C3+ group had higher level of proteinuria (5.6 g/24 h [3.77-8.5], p = 0.073), higher percentage of segmental glomerulosclerosis (20% [12.3-27.2], p = 0.001), and lower levels of eGFR (69 +/- 37.2 mL/min/1.73 m(2), p = 0.029) and serum albumin (2.71 +/- 0.85 g/dL, p = 0.045) at the time of diagnosis. Despite 86.3% of patients in IgM+ C3+ group (19/22) received immunosuppressive treatment, the primary outcome was more common in patients in the IgM+ C3+ group compared with patients in IgM+ C3- and IgM- C3- groups (11 [50%] vs. 2 [9%] and 11 [26.1%] respectively [p = 0.010]). Complete or partial remission rates were lower in patients in the IgM+ C3+ group (5/22, 22.7%), as well (p = 0.043). Multivariate Cox regression analysis revealed that IgM and C3 co-deposition was an independent risk factor associated with primary outcome (hazard ratio 3.355, 95% CI 1.349-8.344, p = 0.009). Conclusions: Glomerular IgM and C3 co-deposition is a predictor of unfavorable renal outcomes in adult patients with primary FSGS.
