The prevalence of pulmonary hypertension after successful tuberculosis treatment in a community sample of adult patients
There are an estimated 155 million survivors of tuberculosis (TB). Clinical experience suggests that post-pulmonary tuberculosis lung disease (PTLD) is an important cause of group 3 pulmonary hypertension (PH). However, TB is not listed as a cause of PH in most guidelines. A cross-sectional, community-based study was conducted in non-health care seeking adults who had successfully completed TB treatment. Subjects underwent questionnaires, spirometry, a six-minute walk distance test (6MWD) and transthoracic echocardiography (TTE). Screen probable PH was defined on TTE as an estimated pulmonary artery peak systolic pressure (PASP) of ≥40mmHg. One hundred adults (71 males) were enrolled, with a mean age of 42 years (SD 13.8 years) and a median of one TB episode (IQR: 1 -2). Co-morbidities included hypertension (21%), diabetes (16%), HIV (10%) and asthma/COPD (5%). Only 25% had no residual symptoms after TB. Probable PH was found in 9%, while 7% had borderline raised PASP values (PASP 35-40mmHg). An association was found between PH and the number of previous TB episodes, with each additional episode of TB increasing the odds of PH-post-TB 2.13-fold (CI 1.17-3.88; P=0.013). All of those found to have PH were smokers or ex-smokers yielding an unadjusted odds ratio for PH-post-TB of 3.67 (95%CI 0.77-17.46). There was no statistical difference in spirometry or 6MWD, between those with and without PH. Neither symptoms nor co-morbidities demonstrated significant association with PH. PH after TB was a common finding in this community-based population. Further research is needed to confirm and determine the significance of these findings
