Improved Gastrointestinal Symptoms and Quality of Life after Conversion from Mycophenolate Mofetil to Enteric-Coated Mycophenolate Sodium in Renal Transplant Patients Receiving Tacrolimus

It is reported that a conversion from mycophenolate mofetil (MMF) to enteric-coated mycophenolate sodium (EC-MPS) relieves gastrointestinal (GI) symptom burden and improves health-related quality of life (HRQoL). However, it is unclear whether renal transplant recipients using tacrolimus receive the same benefit from the conversion. In this prospective, multi-center, open-label trial, patients were categorized into two groups by their GI symptom screening. Equimolar EC-MPS (n=175) was prescribed for patients with GI burdens; those with no complaints remained on MMF (n=83). Gastrointestinal Symptom Rating Scale (GSRS) and Gastrointestinal Quality of Life Index (GIQLI) were evaluated at baseline and after one month. Patients and physicians completed Overall Treatment Effect (OTE) at one month. EC-MPS-converted patients had worse GSRS and GIQLI scores at baseline than MMF-continued patients (all P<0.001). Significant improvements in GSRS and GIQLI scores were observed for EC-MPS-converted patients at one month, but MMF-continued patients showed worsened GSRS scores (all P<0.05). OTE scale indicated that EC-MPS patients improved in overall GI symptoms and HRQoL more than MMF patients did (P<0.001). In tacrolimus-treated renal transplant recipients with GI burdens, a conversion from MMF to EC-MPS improves GI-related symptoms and HRQoL.

A Case of Invasive Fungal Sinusitis after Kidney Transplantation / 대한신장학회지

Acute fulminant invasive fungal sinusitis in an immunocompromised host and bacterial rhinosinusitis with intracranial or orbital extension is challenging to manage. And it sometimes constitutes true otolaryngologic emergencies. In the absence of rapid diagnosis and treatment, these diseases can be fatal. A 57-year-old female was admitted for chills and headache, who received a deceased donor renal transplantation 3 months ago. Paranasal sinus CT showed enhanced soft tissue density and MRI showed low-signal with hyperintense signal of around paranasal sinus cavity. The histological investigation revealed invasive aspergillosis of paranasal sinuses. Clinical improvement occurred after endoscopic sinus surgery and post-operative systemic antifungal therapy with amphotericin B and voriconazole.

Pulmonary Thromboembolism following Mastectomy with Immediate TRAM in the Patients with Breast Cancer : a Prospective Study / 한국유방암학회지

PURPOSE: : Skin-sparing mastectomy with immediate reconstruction provides psychological satisfaction and a good cosmetic effect for patients with breast cancer. However, this procedure takes longer operation time than mastectomy, and the risk of pulmonary thromboembolism (PTE) and deep vein thrombosis may be increased. The purpose of this study was to evaluate the incidence of PTE. METHODS: Between January and May in 2005, 54 breast cancer patients who underwent skin-sparing mastectomy with immediate transverse rectus abdominalis myocutaneous flap (TRAM) at Asan Medical Center were prospectively investigated according to the clinicopathologic data. Patients were placed in compression stockings on the day of operation, and lung perfusion, inhalation scans,and serum D-dimer assays were performed on the first three postoperative days. If findings were suspicious, we performed embolism computed tomography. We compared patient age, body mass index (BMI), clinical risk factors, operative findings, pathologic results, and the clinical course between PTE patients and non-PTE patients. RESULTS: There were 9 cases of intermediate probability and 6 cases of high probability for PTE according to lung perfusion and inhalation scans, and they underwent embolism CT. Eleven patients (20.4%) were diagnosed with embolism CT or with lung perfusion and inhalation scans;2 patients were symptomatic and 9 patients were asymptomatic. There was significant difference between PTE and non-PTE patients for age, but none for BMI, clinical risk factors, operation time, serum D-dimer, or stage. CONCLUSION: The incidence of PTE after mastectomy with immediate TRAM is relatively high, and a strategy for the prevention and treatment of PTE is required. Although age is a risk factor for PTE on this study, future studies are needed to determine the risk factors for and to confirm proper treatment and prevention of PTE.

Symptomatic Pulmonary Thromboembolism following Skin-sparing Mastectomy with Immediate TRAM Reconstruction in Breast Cancer Patients

PURPOSE: A skin-sparing mastectomy (SSM) with immediate reconstruction can give psychological and cosmetic benefits to patients requiring a mastectomy, but a risk of pulmonary thromboembolism (PTE) also exists due to longer operative time. The purpose of this study was to evaluate the clinical characteristics of symptomatic PTE following a SSM with immediate reconstruction. METHODS: Of 216 breast cancer patients underwent a SSM with immediate reconstruction at the Asan Medical Center, between December 2003 and July 2005, 7 in whom postoperative symptomatic PTE developed were included in this study. The ventilation/perfusion scan, embolism CT and serum D-dimer level were checked for those suspected of PTE. RESULTS: The prevalence of symptomatic PTE was 3.2% (7/216). Mean patient age and BMI were 41 years and 24.9 kg/m2, respectively. All patients had undergone TRAM reconstruction, with mean operative time of 562.1 minutes. Postoperative bleeding developed in 4 cases. The pathological stages included 0, I and IIA, which were observed in 1, 4 and 2 cases, respectively. Most common symptom of PTE was dyspnea, which developed in all patients on the second or third postoperative day; followed by chest discomfort and tachypnea. The ventilation/perfusion scans showed 6 with high probabilities. All seven patients were diagnosed as PTE on embolism CT. One patient had DVT on the lower extremities. The most common site of PTE was the superior lobar artery and the segmental branches of the right pulmonary artery. All patients recovered, or were recovering, after the LMWH and warfarin treatment. CONCLUSION: This study has shown that SSM with immediate reconstruction possesses a considerable risk of postoperative PTE. Further study on preoperative prophylaxis and the risk factors is warranted to prevent PTE.

Recurrence and Survival Analysis in Skin-Sparing Mastectomy with Immediate Reconstruction Compared with Conventional Mastectomy / 한국유방암학회지

PURPOSE: A skin-sparing mastectomy (SSM), followed by immediate reconstruction, which has aesthetic advantages, is being increasingly used to treat many early breast carcinomas; however, there are few data regarding the outcome and safety of this procedure. The objective of this study was to evaluate the safety of utilizing a SSM with immediate reconstruction compared with the outcome of a conventional mastectomy. METHODS: A retrospective review was performed on 169 patients who underwent a SSM with immediate reconstruction, and 2102 patients who received a conventional mastectomy between January 1996 and December 2002, at the Asan Medical Center. The patient and tumor characteristics, as well as the types of reconstruction, incidences of recurrence and survival rates were examined. RESULTS: The mean age of the SSM group was younger (39 vs. 47 years, p < 0.001), and the mean tumor size smaller than those of the mastectomy group (2.6 vs. 3.2cm, p = 0.002). Lymph node involvement was present in 39.6% and 48.4% of the SSM and mastectomy groups, respectively (p = 0.24). The proportion at early stages (0 and 1) in the SSM group was higher than those in the mastectomy group (50.9 vs. 30.7%, p < 0.001). In the high-risk patients, postoperative radiation was administered to 24.1 and 54.9% of the SSM and mastectomy group, respectively (p = 0.002). With a median follow-up of 41 months, the recurrence rates for the SSM and mastectomy groups were 11.8 (20 of 169 patients) and 14.4% (303 of 2102 patients), respectively (p = 0.22). There were no differences in the locoregional and distant recurrences between the two groups. The 5-year disease free survivals for the SSM and mastectomy groups were 81.9 and 81.7%, respectively (p = 0.71). The 5-year overall survivals for the SSM and mastectomy groups were 91.7 and 88,8%, respectively (p = 0.13). In a univariate analysis, the factors associated with a recurrence and the survival rates were the tumor stage and a lymph node positive state. CONCLUSION: No significant differences were found in the recurrence and survival rates of the SSM group, with immediate reconstruction, compared to those of the mastectomy only group. A skin-sparing mastectomy, with immediate reconstruction, which has greater aesthetic benefits, appeared to be an oncologically safe treatment option for breast carcinomas.

A Case of Polyoma Virus(PV) Infection in a Renal Allograft Recipient / 대한신장학회잡지

We report one case of renal PV infection after renal allograft transplantation leading to graft dysfunction. According to prior reports, PV induced interstitial nephritis might be a cause of graft loss. Pathologic findings show varying degrees of interstitial infiltration and tubular degenerative changes, which resemble acute cellular rejection. Therapeutic strategies have not yet been developed. Case ; A 23 years old male underwent renal transplantation from his HLA haploidentical 25 year old sister. His renal function had been good with cyclosporin, steroid and azathioprine until 9 months after transplantation, when his serum creatinine level rose to 2.2mg/dl. The renal biopsy revealed diffuse lymphocyte infiltration in the interstitium and feature of the tubulitis. Also, giant tubular epithelial cells with large, hyperchromic nuclei were present. Despite steroid pulsing and OKT3, renal function progressively de- teriorated. After 10 days of OKT3 therapy, the patient suffered from high fever, dyspnea and general aches. A chest X-ray revealed interstitial infiltration in both lung fields and the cytomegalovirus PCR (polymerase chain reaction) test of serum and blood was positive. Intravenous ganciclorvir was administered and immunosuppressants were tapered. 4 months after admission, he lost his graft function and underwent hemodialysis. The aforementioned renal biopsy was retested immunohistochemically. Nuclear inclusions in renal tubular epithelial cells were shown and these inclusions were reacted positively with PV monoclonal antibodies.
