Aim: Patients with HIV have increased cardiovascular risk and pulmonary defects. We investigated the association between impaired pulmonary function (IPF) and arterial stiffening measured by the cardio-ankle vascular index (CAVI) in Ghanaian HIV patients.
Method: Spirometry was used to measure pulmonary indices; forced expiratory volume in 1s (FEV1) and forced vital capacity (FVC) in 79 HIV patients on treatment, 75 HIV treatment naïve patients and 78 non-HIV controls. We also used FEV1/FVC < lower limit of normal as a further index. Arterial stiffness was measured as CAVI using the Vasera device.
Results: Compared to non-HIV controls, CAVI was higher in treatment naïve (6.9 ± 1.4 vs 6.3 ± 1.1 units, p < 0.01) and HIV patients on treatment (8.1 ± 1.4, vs 6.3 ± 1.1, p < 0.01). IPF was detected in 12 (15.2%) HIV patients on treatment, 8 (10.7%) treatment naïve HIV patients and 5 (6.4%) non-HIV controls. Compared to those without IPF, IPF patients had higher CAVI in non-HIV controls (6.5 ± 1.1 vs 5.7 ± 0.8, p < 0.01), treatment naïve HIV patients (7.1 ± 1.8 vs 6.6 ± 1.4, p = 0.023) and HIV patients on treatment (7.8 ± 1.4 vs 8.7 ± 1.2, p < 0.01). In multivariable logistic regression analysis, IPF was independently associated with CAVI [adjusted OR = 1.33 (1.15 – 1.89), p = 0.037] after adjustment for age [1.21 (0.98 – 2.14), p = 0.11], male sex [0.42 (0.32 – 0.91), p = 0.035], current/former smoking status [1.43 (0.47 – 4.01), p = 0.75] and history of tuberculosis infection [1.96 (1.08 – 3.12), p < 0.01].
Conclusion: Ghanaian HIV patients have a high prevalence of impaired respiratory function and arterial stiffening, and these indices are associated with each other.
