High levels of serum prostate-specific antigen due to PSA producing follicular non-Hodgkin's lymphoma

EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 2 2007
Jan Jelrik Oosterheert
Abstract Objective:, Both carcinoma of the prostate and non-Hodgkin's lymphoma are common in elderly patients. Measurement of serum prostate-specific antigen (PSA) is a frequently used tool to diagnose and monitor prostate carcinoma and is generally specific for diseases of the prostate. Case:, We describe a 68-yr-old patient with voiding difficulties and high PSA levels, but without inflammatory or malignant changes upon multiple transrectal ultrasound guided prostate biopsies. Digital rectal examination was normal. Laboratory showed a strongly elevated PSA level (62 ,g/L, Immulight 2000®; DPC, USA). A CT-scan showed a retroperitoneal process with mass in the right pelvis and infiltration of the bladder wall, suggestive for metastatic prostate carcinoma. Surgical excision of an axillary lymph node set the diagnosis at a stage IV follicular lymphoma, Berard grade I to II in which the majority of neoplastic cells expressed PSA. After lymphoma-specific treatment, there was a positron emission tomography (PET) confirmed complete remission with normal PSA levels (6 ,g/L), which still persists. Conclusion:, Although rare, high PSA levels can be due to the presence of non-Hodgkin's lymphoma. Such a diagnosis should be considered when patients present with lymphadenopathy other than regional prostatic lymphadenopathy. [source]

Hypercalcemia and Overexpression of CYP27B1 in a Patient With Nephrogenic Systemic Fibrosis: Clinical Vignette and Literature Review,,

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 6 2009

Abstract Nephrogenic systemic fibrosis (NSF) is a disease of thickened, hard, hyperpigmented skin lesions with or without systemic fibrosis occurring in patients with renal insufficiency and associated with the administration of gadolinium-containing contrast. The pathogenesis of this disease is unclear, and there is no definitive treatment. We describe a 71-yr-old patient with stable chronic lymphocytic leukemia (CLL), end-stage renal disease (ESRD), and NSF who presented with hypercalcemia in 2006. Before onset of renal insufficiency in 2002, serum calcium, phosphorus, and PTH levels were normal. In 2004, the patient began hemodialysis, and he was diagnosed with NSF in 2005, shortly after undergoing an MRI with gadolinium contrast administration. Over the next 6 mo, albumin-corrected serum total calcium levels rose from 9.9 to 13.1 mg/dl (normal range, 8.5,10.5 mg/dl) with normal serum phosphorus levels. On admission in September 2006, 1,25-dihydroxyvitamin D [1,25(OH)2D] levels were elevated at 130.7 pg/ml (normal range, 25.1,66.1 pg/ml). Biopsy of an NSF lesion showed increased 25-hydroxyvitamin D3,1-, hydroxylase (CYP27B1) immunostaining compared with the biopsy from a normal control. This is the first reported association of NSF with hypercalcemia caused by elevated 1,25(OH)2D levels. This metabolic disturbance should be sought in future cases to determine a connection between NSF, 1,25(OH)2D metabolism, and CYP27B1 activation in the skin, which may shed light on the pathogenesis of this unusual local and systemic fibrosing disorder.

Mycotic pseudoaneurysm following a kidney transplant: A case report and review of the literature

PEDIATRIC TRANSPLANTATION, Issue 5 2009
Ignacio Osmán
Abstract:, Vascular complications represent a significant cause of morbidity and mortality following a kidney transplant. Pseudoaneurysms are rare, occurring in approximately 1% of cases. We present a 15-yr-old patient who received a kidney transplant in the right iliac fossa. Thirty-six days following the transplant, the patient was admitted to the hospital because of a marked increase in serum creatinine levels, arterial hypertension, scrotal edema, and lower right limb pain. The patient did not present fever or raised inflammatory markers. A pseudoaneurysm was diagnosed by means of a Doppler echography and a CT. By a selective arteriography of the right iliac artery, we placed a 8 × 5 cm stent to isolate the pseudoaneurysm, due to the high risk of an extensive defect occurring in the arterial wall. Forty-eight h later the patient underwent transplant nephrectomy. Seven days following surgery, the patient experienced febrile syndrome and therefore another CT was carried out which showed a large abscess around the stent. So we decided to perform another intervention in order to drain this abscess. Due to the extensive loss of the arterial wall where the prosthesis was largely exposed, we ligated the common iliac and external iliac arteries, removed the prosthesis and performed a femoro-femoral bypass with the usual subcutaneous positioning of the prosthesis (separate from surgical site). The stent and mural thrombus were sent for culture analysis and Candida albicans was observed. The diagnosis of a pseudoaneurysm in these types of patients continues to be considered as a surgical emergency by the majority of authors. Transplantectomy is the most frequently used treatment technique. Positioning a stent prior to transplantectomy avoids ligature of the iliac artery in the majority of cases. [source]

Renal transplantation outcomes: a comparative analysis between elderly and younger recipients

CLINICAL TRANSPLANTATION, Issue 6 2007
Helena Moisés Mendonça
Abstract:, Renal transplantation is presently the best treatment for end-stage renal disease, although considered contraindicated for elderly patients. However, more investigation is needed due to higher life expectancy rates of the general population and the increasing number of over 60-yr-old patients with chronic renal failure dependant upon dialysis. This study aims to determine graft and patient survival rates of renal transplant patients 60 yr and older compared to a younger group (50,59 yr old). Relevant pre- and post-transplant clinical data related to graft and patient survival in both groups were also investigated. Three-hundred and twenty consecutive renal transplant patients were enrolled in this study and grouped based on age at the time of the transplantation: one-hundred and ten patients at or over 60 yr old (elderly group) and 210 patients ranging from 50 to 59 yr old (younger group). There were no statistical differences in either group regarding clinical characteristics and immunological risk factors. The incidence of acute rejection was higher in the younger group (37.6%) than in the elderly (22.7%) (p = 0.01). Censored to death graft survivals at five yr were respectively 86.7% for patients , 60 yr and 82.1% for patients 50,59 yr old (p = 0.49). Patient survival rates at five yr were respectively 76.2% for patients , 60 yr and 81.6% for patients 50,59 yr old (p = 0.33). Our data show that renal transplantation for elderly patients has similar results to those found in younger individuals, which does not make age, in and of itself, a contraindication for transplantation.
