The relationship between grade of pulmonary hypertension and factors associated with human immunodeficiency virus among patients with HIV infection is poorly documented. This report documents the most extensive attempt made thus far to determine whether a relationship exists between degree of pulmonary hypertension and the following conditions: HIV risk factor, degree of immunosuppression, presence or absence of AIDS, and presence or absence of liver cirrhosis. A retrospective study involving a search of the published literature on primary pulmonary hypertension among HIV cases from 1987 to 1998, using the Medline and Aidsline databases was conducted. Patients for whom secondary causes of pulmonary hypertension could be excluded were selected, and the following information for each was recorded: age, gender, risk factors for HIV infection, HIV disease stage according to the Centers for Disease Control, previous oppor tunistic and neoplastic diseases, CD4 + cell count (cells/L), presence or absence of liver cirrhosis, pulmonary systolic artery pressure level, and lung pathology specimens. Information about the patient's survival time was also recorded. Seventy-six patients were judged to have primary pulmonary hypertension and were included in the study. While no correlation was found between pulmonary systolic artery pressure level and CD4 + cell counts, a statistically significant difference was found between HIV-positive patients with and without AIDS as determined by the Centers for Disease Control criteria with regard to the degree of pulmonary hypertension, expressed as pulmonary systolic artery pressure level (85.4 ± 17 mm Hg vs 71.8 ± 15 mm Hg, p < 0.013). Although a higher PAPS was present in HIV cirrhotic patients, a statistically significant difference was not found between degree of pulmonary hyper tension and evidence of hepatic cirrhosis (85 ±21 mm Hg vs 73.1 ± 15 mm Hg, p < 0.062). Patients with AIDS and primary pulmonary hypertension present a higher degree of pulmonary hypertension than non-AIDS patients. Pulmonary hypertension associated with HIV seems to be related to a cytokine-related stimulation and proliferation of endothelium. High levels of cytokines present in AIDS patients can favor pulmonary hypertension, but the role of a host response to HIV—determined by one or more HLA subtypes—is suspected to enhance high cytokine production levels.
Background. Sarcopenia is a complication and independent risk factor for mortality in patients with liver cirrhosis. To assess the prevalence and influence of sarcopenia on overall survival in a cohort of cirrhotic patients with hepatocellular carcinoma managed in a tertiary center. Abdominal computed tomography of 92 consecutive hepatocellular carcinoma cirrhotic patients, enrolled and followed from 2004 to 2014, were retrospectively studied with a software analyzing the cross-sectional areas of muscles at third lumbar vertebra level. Data was normalized for height, skeletal muscle index (SMI) calculated and presence of Sarcopenia measured. Sarcopenia was defined by SMI ≤ 41 cm2/m2 for women and ≤ 53 cm2/m2 for men with body mass index (BMI) ≥ 25, and ≤ 43 cm2/m2 for men and women with BMI < 25, respectively. Median age at diagnosis was 71.9 years (30.7-86.4) and BMI 24.7 (17.5-36.7), comparable in women 23.1, (17.5-36.7) and men 24.7 (18.4-36.7). A class of CHILD score and BCLC A prevailed (55.4% and 41.3%, respectively); metastatic disease was found in 12% of cases. Sarcopenia was present in 40.2% of cases, mostly in females (62.9%; p = 0.005). Mean overall survival was reduced in sarcopenic patients, 66 (95% CI 47 to 84) vs. 123 (95% CI 98 to 150) weeks (p = 0.001). At multivariate analysis, sarcopenia was a predictor of reduced overall survival, independent of age (p = 0.0027). This retrospective study shows high prevalence of sarcopenia among cirrhotic patients with hepatocellular carcinoma. Presence of sarcopenia was identified as independent predictor of reduced overall survival. As easily measurable by CT, sarcopenia should be determined for prognostic purposes in this patient population.
