Prevalence of severe cardiovascular disease in patients with schizophrenia.

OBJECTIVES: We assessed the prevalence of severe cardiovascular (CV) disease requiring hospitalization among patients with schizophrenia in France. METHOD: We included patients hospitalized with schizophrenia or psychotic disorder during 2015, in five French psychiatric hospitals. Patients with CV disease were defined as those with a correspondent ICD-10 code during a hospital stay in any general hospital, five years before or three years after the psychiatric hospitalization. CV disease included myocardial infarction (MI), stroke, heart failure (HF), coronary artery disease (CAD) or peripheral artery disease. Risk factors such as hypertension, obesity and diabetes were recorded. RESULTS: In total, 4424 patients with schizophrenia were included. Overall, 203 (4,6%) patients were diagnosed with CV disease, 93 (2.1%) with CAD, 86 (1.9%) with HF and 49 (1.1%) with stroke. The prevalence of hypertension, obesity and diabetes was 11.3%, 9.7% and 7.8%. The median (interquartile range) age of patients with MI and diabetes was 57 (49-70) and 56 (48-66) years. CONCLUSION: Patients with schizophrenia develop severe CV disease requiring hospitalization at an early age. These severe events are associated with a high prevalence of risk factors. Early screening and treatment of CV disease and risk factors is important to improve life expectancy and quality of life of these patients.

Incident hyperkalemia may be an independent therapeutic target in low ejection fraction heart failure patients: insights from the HEAAL study.

BACKGROUND: Angiotensin receptor antagonists (ARBs) improve outcomes in patients with heart failure (HF) with reduced left ventricular ejection fraction, but may induce hyperkalemia (HK) and/or a worsening of renal function (WRF). METHODS AND RESULTS: The incidence and risk factors of HK and its inter-relationship with WRF, as well as associations with clinical outcome (death or admission for HF i.e. the primary outcome) in 3846 HF patients enrolled in the double blind HEAAL trial (losartan 150 mg/d vs. 50 mg/d) were assessed. Worsening of renal function was defined as a decrease in eGFR >20% from baseline and HK as serum K >5.5 or >5 mmol/L. Higher dose of losartan increased serum potassium. Episodes of HK >5 mmol/L or WRF occurred at least once in about half of the patients. WRF was associated with higher occurrence of HK (HR 1.19 (1.06-1.34)) and vice versa (HR 1.35 (1.19-1.53)), but preceded HK in only about half of the events. High dose losartan improved outcome despite more frequent WRF and HK, both being independently associated with adverse outcomes in multivariate analyses. CONCLUSIONS: HK and WRF are common in HF patients. Both can be predicted from baseline risk factors and are therefore potentially preventable. Although associated with worse outcome, occurrence of any does not hinder the efficacy of high dose losartan. HK was associated with WRF and worse outcomes. Whether therapy targeting specifically HK may maximize the survival benefit derived from renin angiotensin aldosterone inhibitor use should be appropriately tested in future trials.

Increased serum potassium affects renal outcomes: a post hoc analysis of the Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan (RENAAL) trial.

AIMS/HYPOTHESIS: To assess the effect of an angiotensin receptor blocker (ARB) on serum potassium and the effect of a serum potassium change on renal outcomes in patients with type 2 diabetes and nephropathy. METHODS: We performed a post hoc analysis in patients with type 2 diabetes participating in the Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan (RENAAL) study. Renal outcomes were defined as a composite of doubling of serum creatinine or end-stage renal disease. RESULTS: At month 6, 259 (38.4%) and 73 (10.8%) patients in the losartan group and 151 (22.8%) and 34 (5.1%) patients in the placebo group had serum potassium ≥5.0 mmol/l and ≥5.5 mmol/l, (p < 0.001), respectively. Losartan was an independent predictor for serum potassium ≥5.0 mmol/l at month 6 (OR 2.8; 95% CI 2.0-3.9). Serum potassium at month 6 ≥ 5.0 mmol/l was in turn associated with increased risk for renal events (HR 1.22; 95% CI 1.00-1.50), independent of other risk factors. Adjustment of the overall treatment effects for serum potassium augmented losartan's renoprotective effect from 21% (6-34%) to 35% (20-48%), suggesting that the renoprotective effects of losartan are offset by its effect on serum potassium. CONCLUSIONS/INTERPRETATION: In this study, we found that treatment with the ARB losartan is associated with a high risk of increased serum potassium levels, which is in turn associated with an increased risk of renal outcomes in patients with diabetes and nephropathy. Whether additional management of high serum potassium would further increase the renal protective properties of losartan is an important clinical question.

[Corticotherapy in aggressive chronic hepatitis (ACH)]. / Corticoterapia in hepatita cronica agresiva.

48 patients with the diagnosis of ACH, admitted in the interval 1972-1981 and subjuected to corticotherapy were investigated by hepatic puncture biopsy with Vim-Silverman needls. The dose of prednison was of 15-20 mg daily for 2-4 years, with a mean 20 months. Corticotherapy was efficient in 73% of the cases, stabilization of the clinical and hepatic functional pictures being obtained. In 17% of the cases the hepatic process persited unmodified and in 10% ACH evolved towards cirrhosis.
