Low muscle mass and high visceral fat mass predict mortality in patients hospitalized with moderate-to-severe COVID-19: a prospective study.

Introduction: The severity of coronavirus disease 2019 (COVID-19) has been positively correlated with several comorbidities. The primary outcome of the study was to assess the relationship between the mortality and severity of COVID-19 and obesity classes according to BMI, visceral adipose tissue (VAT) area, s.c. adipose tissue area, muscle area (MA), and leptin levels. Methods: In this prospective cohort study, 200 patients hospitalized with moderate-to-severe COVID-19 underwent an unenhanced CT of the thorax and laboratory tests, and leptin levels between June and August 2020 were obtained. Results: Our study included 200 patients (male 52%; mean age: 62 (49-74) years; obesity (BMI > 30): 51.5%)). Fifty-eight patients (23.5%) were admitted to the intensive care unit and 29 (14.5%) died. In multivariate logistic regression (corrected for leptin, sex, age, and serum biomarkers) and receiver operating characteristic curve analyses, high VAT > 150 cm2 (odds ratio (OR): 6.15; P < 0.002), MA < 92 cm2 (OR: 7.94; P < 0.005), and VAT/MA ratio > 2 (OR: 13.9; P < 0.0001) were independent risk factors for mortality. Indeed, the Kaplan-Meier curves showed that patients with MA < 92 cm2 and without obesity (BMI < 30) had a lower survival rate (hazard ratio between 3.89 and 9.66; P < 0.0006) than the other groups. Leptin levels were not related to mortality and severity. Conclusion: This prospective study reports data on the largest number of hospitalized severe COVID-19 patients and pinpoints VAT area and MA calculated by CT as predictors of COVID-19 mortality.

Pain in hospitalized HIV-positive patients: clinical and therapeutical issues.

Pain is frequently reported by patients infected with Acquired Immunodeficiency Virus (HIV), and its causes and specific treatment should be appropriately investigated. We evaluated 197 hospitalized HIV-positive patients with serial interviews and analysis of prescriptions and clinical evolution charts. The main characteristics of pain reported by these patients were: high intensity (60.7%), high frequency (72.0%) and well-known causes (88.8%). Fifty-two per cent of the patients reported persistent or frequent pain during the two weeks before hospital admission. Parameters such as gender, educational level and Karnofsky Index showed no direct relation to the presence or absence of pain. The most commonly affected sites were the head (28.0%) and the abdomen (26.2%). The frequency of indications of pain in the clinical evolution charts (46.2%) was considerably lower than the frequency of complaints reported by patients during the interviews (76.3%). Pain was undertreated in 83.2% of patients, both due to poor efficacy of the prescribed medications and to the excessive and inefficient use of standing order ("if necessary") regimens. We observed that pain was better managed during the hospitalization period, although this cannot be explained by improvement of the analgesic treatment; it might be due to successful treatment of the underlying disease. We concluded that pain reported by hospitalized HIV-positive patients is often underestimated and inadequately treated by assisting doctors, in spite of its severity and frequency.

Bone paracoccidioidomycosis in the HIV positive patient [Letter]

AIDS patients are vulnerable to infection by opportunistic microbes, including various fungi such as Pneumocystis carinii, Cryptococcus neoformans, Histoplasma capsulatum, Candida albicans and many others. However, the association of AIDS and infection with Paracoccidioides brasiliensis has been rarely recorded. We report a case of an HIV-positive patient with bone infections by this fungus with a clinical form not previously published. This clinical presentation included primarily a massive bone lesion, but it did not included the lymphatic and disseminated disease described in HIV-positive patients. The patient responded well to medical and surgical treatment. We suggest that patients with moderate, rather than severe, immunosuppression may have forms of paracoccidioidomycosis with a patho;ogic process intermediate to those sen in the immunologically normal host and the full AIDS syndrome.
