Summaryobjectives To identify the main clinical and laboratory features of disseminated histoplasmosis (DH) in human immunodeficiency virus (HIV) patients and compare them with those of HIV patients with other opportunistic diseases.methods Retrospective study of HIV patients comparing the clinical and laboratory data of patients with and without DH. Univariate and multivariate analyses were performed to verify the risk factors related to DH.results In total, 378 HIV patients were included, 164 with DH and 214 with other opportunistic diseases. Acute renal failure, respiratory insufficiency and septic shock were more frequent in DH patients, who also had a higher mortality (32% vs. 14%, P < 0.001). Independent risk factors for DH were: acute renal failure [odds ratio (OR) 5.2; 95% confidence interval (CI) 3.2-8.5; P < 0.001], splenomegaly (OR 3.4; 95% CI 1.19-9.9; P < 0.001), respiratory insufficiency (OR 2.7 95% CI 1.5-5.0; P < 0.001), proteinuria (OR 2.7; 95% CI 1.3-5.2; P = 0.03), hypotension (OR 2.5; 95% CI 1.2-5.0; P = 0.008), hepatomegaly (OR 2.4; 95% CI 1.2-4.8; P = 0.01), cutaneous lesions (OR, 1.9; 95% CI 1.0-3.3; P = 0.02) and weight loss (OR 1.8; 95% CI 1.0-3.1; P = 0.03).conclusion Our results suggest that DH is a severe opportunistic disease with high mortality rate, which should be promptly recognized in order to provide early specific treatment.

Despite their significant influence on the quality of life, depressive symptoms are not usually included as a clinical parameter in the evaluation of hemodialysis patients. We aimed to identify depressive symptoms and associated risk factors in a large group of individuals with end-stage renal disease (ESRD) on chronic hemodialysis. This was a cross-sectional study of 400 consecutive patients. Cases were analyzed according to the presence/absence of depressive symptoms. All individuals were investigated by interview, and all variables were measured concurrently. Depressive symptoms were evaluated by the Beck Depression Inventory (BDI-II ≥16) and sleep quality by the Pittsburgh Sleep Quality Index (PSQI > 5). Among the 400 patients (59% male), depressive symptoms were present in 77 (19.3%). Depressive symptoms were more common in women and were independently associated with poor sleep quality (P = <0.005), unemployment (P = 0.001), diabetes (P = 0.02), hypoalbuminemia (P = 0.01), low education (P = 0.03), and pruritus (P = 0.04). Women with ESRD on chronic hemodialysis are at increased risk of depression. Furthermore, unemployment and the presence of diabetes, hypoalbuminemia, low education, and pruritus are significantly associated with depressive symptoms. Depressive symptoms are also independently associated with poor quality sleep and studies about the effects of sleep hygiene therapy on depressive symptoms are warranted.

Background:Acute kidney injury (AKI) is an uncommon but serious complication after trauma. The objective of this study was to evaluate the prevalence, clinical characteristics and outcome of AKI after trauma.Patients and Methods:This was a retrospective study performed from January 2006 to January 2008 in an emergency specialized hospital in Fortaleza city, northeast of Brazil. All patients with AKI admitted in the study period were included. Prevalence of AKI, clinical characteristics and outcome were investigated.Results:Of the 129 patients admitted to the intensive care unit (ICU), 52 had AKI. The mean age was 30.1 ± 19.2 years, and 79.8% were males. The main causes of AKI were sepsis in 27 cases (52%) and hypotension in 18 (34%). Oliguria was observed in 33 cases (63%). Dialysis was required for 19 patients (36.5%). Independent risk factors associated with AKI were abdominal trauma [odds ratio (OR) = 3.66, P = 0.027] and use of furosemide (OR = 4.10, P = 0.026). Patients were classified according to RIFLE criteria as Risk in 12 cases (23%), Injury in 13 (25%), Failure in 24 (46%), Loss in 1 (2%) and End-stage in 2 (4%). Overall in-hospital mortality was 95.3%. The main cause of death was sepsis (24%). Mortality was 100% among patients with AKI.Conclusions:AKI is a fatal complication after trauma, which presented with a high mortality in the studied population. A better comprehension of factors associated with death in trauma-associated AKI is important, and more effective measures of prevention and treatment of AKI in this population are urgently needed.
