Abstract Thrombotic microangiopathy (TMA) is a recognized complication of malignant hypertension (HTN). Such patients have blood pressures ,200/140 mmHg but the condition is defined by the presence of papilledema and is frequently complicated by acute renal failure. Here we report two patients with severe HTN (systolic ,180 mmHg or diastolic ,120 mmHg), TMA, thrombocytopenia, renal failure, and, in one case, neurological changes (4 of 5 manifestations of the TTP pentad). A 50-year-old male with HTN presented with blurred vision, dizziness, headache, confusion, renal failure, and a TMA (PLT = 39 × 109/L and LD = 2,781 normal <600 U/L). On presentation, BP was 214/133 mmHg and an ophthalmic exam demonstrated no papilledema. With HTN control over 7 days, his platelet count rebounded (220 × 109/L), LD declined (1,730 U/L), and mental status improved. A 60-year-old female with diabetes, HTN, Lupus erythematosus, mild chronic anemia, and thrombocytopenia presented with abdominal pain, shortness of breath, renal failure, and a TMA (PLT = 83 × 109/L and LD = 2,929 U/L). Blood pressures were 180,210/89,111 mmHg and ophthalmic exam demonstrated no papilledema. With HTN control over 8 days, her platelet count rebounded (147 × 109/L), and LD declined (1,624 U/L). Although in both cases a diagnosis of TTP was considered because of overlap with the classic diagnostic pentad, neither received plasmapheresis. TTP is a diagnosis of exclusion, where there is no other likely diagnosis to explain the TMA. In cases of severe HTN (with or without papilledema), the diagnosis of TTP should be held in abeyance until the effect of HTN control can be assessed. J. Clin.

Emerging Insights in the First-Step Use of Antihypertensive Combination Therapy

JOURNAL OF CLINICAL HYPERTENSION, Issue 2007
Keith Norris MD
The blood pressure (BP) goals set by hypertension management guidelines (<140/90 mm Hg in uncomplicated hypertension; <130/80 mm Hg in type 2 diabetes or kidney disease) are not being achieved in a high proportion of patients, partly because monotherapy is insufficient in many patients. In particular, patients with uncontrolled moderate or severe hypertension and/or associated cardiovascular risk factors remain at high risk for cardiovascular events and hypertensive emergency. In recognition of the urgency of treating moderate and severe hypertension, the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) advocates the initial use of 2-drug therapies in patients with systolic BP levels >20 mm Hg above goal or diastolic BP level >10 mm Hg above goal. Regimens should usually include a thiazide diuretic and, for patients with diabetes or kidney disease, an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker. Recently, clinical trial data have shown that first-step antihypertensive treatment of moderate and severe hypertension with carefully chosen fixed-dose combinations provides a high rate of BP goal achievement, a simplified dosing regimen, and superior tolerability compared with monotherapy.

SUMMARY: Aim: To determine the prevalence of antiphospholipid syndrome nephropathy (APSN) in Thai systemic lupus erythematosus (SLE) patients who underwent renal biopsy and to compare the relationship of renal histopathology and other significant clinical parameters between SLE patients with and without APSN. Methods: A retrospective analysis was undertaken in systemic lupus erythematosus patients (n = 150, 44 <15 years old, 106 0e;15 years old) who underwent renal biopsy. The specimens were evaluated for histological features of APSN and other significant clinical parameters. The result of antiphospholipid antibodies, clinical course, and renal function from chart review were analysed. Results: The prevalence of APSN in systemic lupus erythematosus patients who underwent renal biopsies was 34% (16% in <15-year-old group, 41.5% in 0e;15-year-old group). APSN was associated with more severe hypertension (P = 0.002 for systolic and P = 0.004 for diastolic blood pressure), acute renal failure (P = 0.003), persistent heavy proteinuria (P < 0.001 for 4+ proteinuria), severe lupus nephritis (class III and IV, P = 0.014, high activity and chronicity indices, P < 0.001) and a tendency to progress to end-stage renal disease. Conclusion: Systemic lupus erythematosus patients who underwent renal biopsies in our institute showed a prevalence of APSN comparable to those in western countries. The presence of APSN was significantly higher in the adult than in the paediatric population. Its association with poor prognostic indicators suggests poor renal outcome. Clinicians should be aware of this condition in order to give proper care to systemic lupus erythematosus patients. [source]


A composite pheochromocytoma/ganglioneuroblastoma of the adrenal gland,

PEDIATRIC BLOOD & CANCER, Issue 7 2010
Elizabeth Lee Thiel MD
Abstract A 9-year-old female presented with a large abdominal mass. At surgery, the mass was noted to arise from the right adrenal gland. As the mass was manipulated, the patient developed severe hypertension. The final diagnosis was a cystic composite-pheochromocytoma/ganglioneuroblastoma. This compound adrenal tumor is only the fourth case reported in a child. Because composite pheochromocytomas are rare in the pediatric population, the management, optimal surveillance schedule and outcomes have not been characterized.

Biopsy-Diagnosed Renal Disease in Patients After Transplantation of Other Organs and Tissues

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 9 2010
A. Schwarz
Renal function deteriorates in about half of patients undergoing other transplants. We report the results of 105 renal biopsies from 101 nonrenal transplant recipients (bone marrow 14, liver 41, lung 30, heart 20). Biopsy indications were protracted acute renal failure (9%), creatinine increases (83%), heavy proteinuria (22%), or renal insufficiency before re-transplantation (9%). Histological findings other than nonspecific chronic changes, hypertension-related damage, and signs of chronic CNI toxicity included primary glomerular disease (17%), mostly after liver transplantation (21%) or after bone marrow transplantation (29%), and thrombotic microangiopathy (TMA) namely (10%). TMA had the most serious impact on the clinical course. Besides severe hypertension, one TMA patient died of cerebral hemorrhage, 5 had hemolytic-uremic syndrome, and 6 rapidly developed end-stage renal failure. TMA patients had the shortest kidney survival post-biopsy and, together with patients with acute tubular injury, the shortest kidney and patient survival since transplantation. Nine TMA patients had received CNI, 3 of them concomitantly received an mTOR-inhibitor. CNI toxicity is implicated in most patients with renal failure after transplant of other organs and may play a role in the development of TMA, the most serious complication. However, decreased renal function should not be routinely ascribed to CNI. [source]


Cerebral gunshot wounds: a score based on three clinical parameters to predict the risk of early mortality

ANZ JOURNAL OF SURGERY, Issue 11 2009
Michael Stoffel
Abstract Background:, To provide a score to predict the risk of early mortality after single craniocerebral gunshot wound (GSW) based on three clinical parameters. Methods:, All patients admitted to Baragwanath Hospital, Johannesburg, South Africa, between October 2000 and May 2005 for an isolated single craniocerebral GSW were retrospectively evaluated for the documentation of (i) blood pressure (BP) on admission; (ii) inspection of the bullet entry and exit site; and (iii) initial consciousness (n= 214). Results:, Conscious GSW victims had an early mortality risk of 8.3%, unconscious patients a more than fourfold higher risk (39.2%). Patients with a systolic BP between 100 and 199 mm Hg had an 18.2% risk of mortality. Hypotension (<100 mm Hg) doubled this risk (37.7%) and severe hypertension (,200 mm Hg) was associated with an even higher mortality rate of 57.1%. Patients without brain spilling out of the wound (,non-oozer') exhibited a mortality of 19.7%, whereas it was twice as high (43.3%) in patients with brain spill (,oozer'). By logistic regression, a prognostic index for each variant of the evaluated parameters could be established: non-oozer:0, oozer:1, conscious:0, unconscious:2, 100 ,RRsys < 200 mm Hg:0, RRsys < 100 mm Hg:1, RRsys, 200 mm Hg:2. This resulted in a score (0,5) by which the individual risk of early mortality after GSW can be anticipated. Conclusions:, Three immediately obtainable clinical parameters were evaluated and a score for predicting the risk of early mortality after a single craniocerebral GSW was established. [source]


Guidelines for the management of hypertensive disorders of pregnancy 2008

AUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 3 2009
Sandra A. LOWE
This is the Executive Summary of updated guidelines developed by the Society of Obstetric Medicine of Australia and New Zealand for the management of hypertensive diseases of pregnancy. They address a number of challenging areas including the definition of severe hypertension, the use of automated blood pressure monitors, the definition of non-proteinuric pre-eclampsia and measuring proteinuria. Controversial management issues are addressed such as the treatment of severe hypertension and other significant manifestations of pre-eclampsia, the role of expectant management in pre-eclampsia remote from term, thromboprophylaxis, appropriate fluid therapy, the role of prophylactic magnesium sulfate and anaesthetic issues for women with pre-eclampsia. The guidelines stress the need for experienced team management for women with pre-eclampsia and mandatory hospital protocols for treatment of hypertension and eclampsia. New areas addressed in the guidelines include recommended protocols for maternal and fetal investigation of women with hypertension, preconception management for women at risk of pre-eclampsia, auditing outcomes in women with hypertensive diseases of pregnancy and long-term screening for women with previous pre-eclampsia.

Getting to goal in complex patients

CLINICAL CARDIOLOGY, Issue S2 2003
C. Venkata
Abstract Traditionally, the term complex hypertension has been applied to patients who have clinical evidence of target organ damage. However, this definition can be expanded to include many hypertensive patients who either present without manifest disease but harbor silent concomitant organ damage, or belong to a high-risk group and are likely to develop such damage. Thus, the number of patients who deserve special consideration as complex patients is considerable. Various factors may contribute toward classifying a patient as having complex hypertension. These include severe hypertension; concomitant conditions such as diabetes, chronic renal insufficiency, coronary artery disease, or congestive heart failure; and high-risk populations such as the elderly and African Americans. Recent evidence demonstrates that aggressive goal blood pressure (BP)-lowering therapy is the key toward halting the progression of vascular disease. Although the choice of initial therapy seems less important than achieving goal B P, the drug selected must impart efficacy, organ protection, and tolerability. Combination therapy consisting of calcium-channel blockers and angiotensin-converting enzyme inhibitors seems to achieve these desirable effects. Several clinical trials have demonstrated these agents to have favorable effects on BP and organ protection even in complex hypertension, particularly when used in combination. [source]
