SDB comprised of obstructive apneas, hypopneas, and nocturnal hypoxemia is prevalent in PH and cannot be accurately predicted by sleep apnea signs and symptoms or diurnal rest and exercise SaO(2). The association of AHI and T90% with mPAP suggests a potential relationship between the pathophysiology of sleep-disordered breathing and PH.

Patients over 10 years of age with cyanotic congenital heart disease (CCHD) risk developing significant glomerular proteinuria, a condition called cyanotic nephropathy. Even though the pathogenesis of glomerulopathy associated with CCHD is still unclear, a potential mechanism is hyperviscosity-induced decrease in peritubular capillary blood flow leading to an increase in glomerular capillary pressure, in turn resulting in proteinuria. Although angiotensin-converting enzyme (ACE) inhibitors have been traditionally used in the treatment of these patients with cyanotic nephropathy, they may, however, not be well tolerated. Here we present a case of an adult patient with CCHD who could not tolerate an ACE inhibitor but showed improvement and stabilisation of her renal function following treatment with repeated phlebotomies.

Idiopathic pulmonary fibrosis (IPF) is a debilitating, progressive, and fatal fibrotic lung disease with a poor prognosis. Antifibrotic therapy slows but does not halt disease progression. Patient education and management needs change during disease progression. Management is complicated by comorbidities, adverse events associated with antifibrotic therapy, and difficulties with long-term oxygen therapy and pulmonary rehabilitation. Treating IPF requires coordination between physicians and nurses in community and interstitial lung disease center settings. This review provides guidance for the healthcare professional who manages the essential aspects of care in IPF from diagnosis, through disease progression, and to the end of life.
