Simple, sensitive and specific predictors of mortality in the critically ill remain elusive goals, and brain natriuretic peptide and venous lactate are the subjects of recent studies. The role of vasopressin in sepsis continues to be the focus of much research interest. Dose ranging studies, potential adverse effects, and selective V1 agonists are discussed below in recent trials. Finally the use of erythropoietin in the critically ill continues to be studied but many continue to urge caution for widespread use outside of clinical trials.

Autosomal dominant polycystic kiney disease is a hereditary systemic disorder, characterized by the developement of cysts, mainly in the kidney and liver, also with gastrointestinal and cardiovascular abnormalities. It affects 4 to 6 million people wordwide and accounts for end-stage renal disease in 7-10% of dialysis patients. The genetic penetrance is 100%, all affected individuals develop renal cysts until 70 years of age, and because of a great renal function reserve only about 50% of patients develop some degree of renal failure until the age of 60. Autosomal dominant polycystic kiney disease is a heterogeneous disorder, from a clinical as well as from a genetic point of view. There are at least three genes responsible for the disease: PKD-1 gene localized on chromosome 16p in the 16p13.3 segment which encodes Polycystin 1 protein similar to membrane receptor, PKD-2 gene localized on chromosome 4q in 4q13-23 segment which encodes Polycystin 2 protein wery similar to voltage L type Ca++ channel as well as Na+ channel and PKD-3 gene of unknown localization. Specific proteins participate in regulation od cell proliferation, apoptosis, secretion, polarity, cell-matrix interactions as cell-cell interactions and lead to the developement of cystic kidney disease. Renal manifestations of disease include structural (cyst development), functional (concentration alility falls), endocrine (renin erythropoietin) abnormalities and extra- renal manifestations. A routine diagnostic methods are good case-history about cystic kidney disease in family, ultrasonographic examination of kidneys and computerized tomography. In therapy of autosomal dominant polycystic kiney disease, low protein diets may help, treatment of arterial hypertension with ACE inhibitors and angiotensin II receptor blockers, the vasopressin V2 antagonists (VSR), rapamycin and long-acting somatostatin analogue may have some benefit.

Cardio-renal syndromes are disorders of the heart and kidney wherein acute or long-term dysfunction in one organ may induce acute or long-term dysfunction of the other. Because of this complex organ interaction, management of cardiorenal syndrome must be tailored to the underlying pathophysiology. Clinical guidelines exist for the treatment of heart failure or renal failure as separate conditions. Thus far, however, there has been no consensus about managing patients with cardio-renal and reno-cardiac syndromes. Pharmacologic treatment remains a controversial subject. Standard cardiac drugs such as diuretics and inotropes may have limited effect because resistance often develops after long-term use. Recent studies of patients with acute cardio-renal syndromes have focused on newer therapies, including phosphodiesterase inhibitors, vasopressin antagonists, adenosine A1 receptor antagonists, and renal protective dopamine. Initial clinical trials of these agents have shown encouraging results in some patients with heart failure, but have failed to demonstrate a clear superiority over more conventional treatments. Similarly, the benefits of diuretics, aspirin, erythropoietin agents, and iron supplements for management of chronic cardiorenal syndromes are unknown.

Arginine vasopressin (AVP) made by hypothalamic neurons is released into the circulation to stimulate water resorption by the kidneys and restore water balance after blood loss. Patients who lack this antidiuretic hormone suffer from central diabetes insipidus. We observed that many of these patients were anemic and asked whether AVP might play a role in red blood cell (RBC) production. We found that all three AVP receptors are expressed in human and mouse hematopoietic stem and progenitor cells. The AVPR1B appears to play the most important role in regulating erythropoiesis in both human and mouse cells. AVP increases phosphorylation of signal transducer and activator of transcription 5, as erythropoietin (EPO) does. After sublethal irradiation, AVP-deficient Brattleboro rats showed delayed recovery of RBC numbers compared to control rats. In mouse models of anemia (induced by bleeding, irradiation, or increased destruction of circulating RBCs), AVP increased the number of circulating RBCs independently of EPO. In these models, AVP appears to jump-start peripheral blood cell replenishment until EPO can take over. We suggest that specific AVPR1B agonists might be used to induce fast RBC production after bleeding, drug toxicity, or chemotherapy.
