Prognostic impact of systemic inflammatory diseases in elderly patients with congestive heart failure.

BACKGROUND AND AIMS: Inflammation is part of the pathophysiology of congestive heart failure (CHF). However, little is known about the impact of the presence of systemic inflammatory disease (SID), defined as inflammatory syndrome with constitutional symptoms and involvement of at least two organs as co-morbidity on the clinical course and prognosis of patients with CHF. METHODS AND RESULTS: This is an analysis of all 622 patients included in TIME-CHF. After an 18 months follow-up, outcomes of patients with and without SID were compared. Primary endpoint was all-cause hospitalization free survival. Secondary endpoints were overall survival and CHF hospitalization free survival. At baseline, 38 patients had history of SID (6.1%). These patients had higher N-terminal pro brain natriuretic peptide and worse renal function than patients without SID. SID was a risk factor for adverse outcome [primary endpoint: hazard ratio (HR) = 1.73 (95% confidence interval: 1.18-2.55, P = 0.005); survival: HR = 2.60 (1.49-4.55, P = 0.001); CHF hospitalization free survival: HR = 2.3 (1.45-3.65, P < 0.001)]. In multivariate models, SID remained the strongest independent risk factor for survival and CHF hospitalization free survival. CONCLUSION: In elderly patients with CHF, SID is independently accompanied with adverse outcome. Given the increasing prevalence of SID in the elderly population, these findings are clinically important for both risk stratification and patient management.

["HAART-attack" in young female HIV-patient]. / "HAART-Attack" bei junger HIV-Patientin.

Since the implementation of highly active antiretroviral therapy (HAART) there is a dramatic decline in morbidity and mortality due to reduction of opportunistic infections in HIV-infected patients resulting in improved prognosis. Unfortunately, patients receiving HAART are at risk for metabolic complications, which may induce the development of coronary artery and cerebrovascular disease, particularly in young patients and in the presence of additional cardiovascular risk factors. A 30-years old female HIV-infected patient who developed an acute myocardial infarction is described.

[Metformin-associated lactic acidosis in a patient with pre-existing risk factors]. / Laktatazidose in Assoziation mit Metformin bei einer Patientin mit vorbestehenden Risikofaktoren.

Lactic acidosis is a serious clinical situation associated with a high case fatality rate. Lactic acidosis is particularly found in conditions with an insufficient supply of oxigen in the tissue. Other causes for lactic acidosis can be hepatic or renal insufficiency. For the therapy of overweight patients with type 2 diabetes metformin is the first choice if diet and physical training have been ineffective. Metformin, however, has the potential to increase serumlactate. Therefore its ability to cause lactic acidosis is controversely discussed. We present a 64-year-old female patient with metformin-associated lactic acidosis. She had several pre-existing risk factors to develop a lactic acidosis. On her referral to the hospital she suffered from acute renal failure which is considered to be a contraindication for the use of metformin.
