The authors would like to report an error that appeared in the Conclusions section of the abstract of a recently published article [1]. In contrast to what was stated in the original abstract [1], the body mass index, waist circumference and neck circumference had a better predictive value for moderate-severe sleep disordered breathing in HIV-negative men compared with HIV-positive men. The corrected version of the full abstract is shown below. The publishers apologize for this mistake.
Background
Body mass index (BMI), waist circumference (WC) and neck circumference (NC) are important screening tools for sleep disordered breathing (SDB); however, the utility of anthropometry for this purpose has not been evaluated among HIV-positive patients.
Methods
HIV-negative men (n=60), HIV-positive men receiving highly active antiretroviral therapy (HIV-positive/HAART; n=58) and HIV-positive men not receiving HAART (HIV-positive/no HAART; n=41) from the Multicenter AIDS Cohort Study underwent a nocturnal sleep study and anthropomorphic assessment. Moderate-severe SDB was defined as an apnea/hypopnea event rate ≥15 episodes/h. Receiver operating characteristic (ROC) curves were used to compare the ability of different anthropometric measurements to predict SDB within each group.
Results
Moderate-severe SDB was found in 48% of men (HIV-negative [57%], HIV-positive/HAART [41%] and HIV-positive/no HAART [44%]). The performance of BMI, WC and NC to predict SDB was excellent among the HIV-negative men (ROC areas under the curve [AUCs] 0.83, 0.88 and 0.88, respectively) and fair among the HIV-positive/HAART group (AUC 0.71, 0.77 and 0.77, respectively). By contrast, these measurements had no predictive value in the HIV-positive/no HAART group (AUC 0.43, 0.41 and 0.45, respectively). Moreover, in the HIV-positive/no HAART group, moderate-severe SDB was independently associated with serum C-reactive protein ≥3.0 mg/l (odds ratio 6.9; P=0.04) and HIV RNA>10,000 copies/ml (odds ratio 7.1; P=0.05).
Conclusions
BMI, WC and NC had a better predictive value for moderate-severe SDB in HIV-negative men compared with HIV-positive men, and had no value among HIV-positive/no HAART men. Among this latter group, systemic inflammation might contribute to the pathogenesis of SDB.
