As yet, she has not received formal anticoagulation. phaeochromocytoma. == Case presentation == A 51-year-old woman was admitted with a 1-day history of left-sided flank pain. She had no significant medical history, was not taking regular medications and had a family history of essential hypertension. Examination was unremarkable other than left-sided abdominal tenderness and blood pressure of 167/113 mm Hg. Urinalysis was positive for protein and blood. The only abnormalities noted on initial blood investigations included a Fumalic acid (Ferulic acid) modestly raised C reactive protein of 18 mg/litre (<6) and elevated white cell count of 15.5109cells/litre. A diagnosis of urine tract infection or left renal colic was proposed, yet the CT urogram was reported as normal. She was treated with antibiotics but over the following week her flank Fumalic acid (Ferulic acid) pain deteriorated, being associated with episodic sweats, vomiting, a deterioration of hypertension (recorded at 205/125 mm Hg) together with a tachycardia of 120 beats/min. A repeat CT scan of the chest, abdomen and pelvis revealed lung airspace shadowing consistent with pulmonary oedema and a 53 cm hypodense abnormality of the left adrenal gland consistent with haemorrhage. This was not seen on review of the original CT urogram. She was transferred to the high dependency unit for monitoring and respiratory support. In view of the history and the presence of the adrenal mass, a diagnosis of infarction/haemorrhage within a phaeochromocytoma was considered and she was initially treated with phenoxybenzamine. Subsequent investigation revealed an isolated elevation of normetepinephrine of 7.58 mol/24 h (<4.0) on 24 h urinary catecholamine assessment together with a suboptimal cortisol response (433 nmol/litre) 30 min after 250 g intravenous synacthen (normal response (NR) >550 nmol/litre). She was treated with intravenous hydrocortisone 50 mg three times a day together with increasing doses of phenoxybenzamine. Despite effective control of her blood pressure, her renal function declined with Fumalic acid (Ferulic acid) serum creatinine rising to a peak of 517 mol/litre (NR 50100). Further investigations revealed a negative antiglomerular basement membrane antibody. A clotting profile showed an elevated activated partial thromboplastin time of 54.7 s (22.031.5), anti-cardiolipin antibodies were positive and other haematological indices were consistent lupus anticoagulant (table 1). Antiphospholipid syndrome was therefore suggested as a cause for the haemorrhage of a possible underlying phaeochromocytoma. She underwent renal biopsy which reported widespread ischaemic change and small vessel hyalinosis. No definite microthrombi were seen but appearances were suggestive of resolving thrombosis. == Table 1. == Results of haematological and immunological indices Abs, antibodies; ANA, anti-nuclear antibodies; APTT, activated partial thromboplastin time; dsDNA, double-stranded DNA. Anti-b2GP1 antibodies are thought to be more closely associated than anti-cardiolipin antibodies with thrombosis in patients with a history of anti-phospholipid antibody-associated disease. The negative ANA and crithidia Rabbit Polyclonal to MMP12 (Cleaved-Glu106) anti-DNA immunofluorescence tests reveal the anti-dsDNA ELISA result can be a fake positive because of nonspecific binding. She was known for an endocrine opinion for administration of that which was regarded as an root phaeochromocytoma. Nevertheless, the analysis was reconsidered in the light of no earlier suggestive symptoms as well as the primarily regular CT urogram. The analysis was felt to become pseudophaeochromocytoma because of adrenal haemorrhage and infarction from the antiphospholipid syndrome. This was backed by a decrease and normalisation of urine catecholamine concentrations during hospitalisation (desk 2). == Desk 2. == Serial 24 h urine catecholamine concentrations During the period of the entrance phenoxybenzamine was transformed to amlodipine and consequently her blood circulation pressure improved to 104/70 mm Hg of which period antihypertensives had been withdrawn. Renal function continuing to improve having a serum creatinine 244 mol/litre at release. A repeat brief synacthen test demonstrated a continual suboptimal adrenal response having a cortisol increasing to 215 nmol/litre at 30 min after intravenous synacthen. She was taken care of on hydrocortisone 20 mg morning hours and 10 mg night daily and provided fludrocortisone 100 g once daily. At.
