Background: Often, patients with idiopathic interstitial pneumonia (IIP) have certain specific clinical features to suggest an autoimmune disease but do not justify the current rheumatologic classification systems to fit into a diagnosis of connective tissue disease (CTD)-associated IIP. There is a great paucity of clinical, serological, and radiological data of these patients from India. Aim: The aim was to study the clinicoradiological and autoantibody profile in patients with interstitial pneumonia with autoimmune features (IPAF). Methodology: It was a prospective, observational study conducted in a tertiary care center between December 2015 and December 2016. A total of 30 patients who satisfied the criteria for IPAF according to the American Thoracic Society/European Respiratory Society research were included in the study. Results: All 30 patients satisfied IPAF criteria, but they did not meet the immunological criteria for CTD. Majority of them were female (86.67%) and nonsmokers. The mean age was 52.5 ± 14.5 years. The most common clinical symptom was inflammatory arthritis in 20 (66.67%) patients, followed by Raynaud's phenomenon in 5 (16%) patients. Nonspecific interstitial pneumonia was the most common radiological pattern seen in 20 (66.67%) patients, while antinuclear antibody (1:320) was the most common autoantibody positive in 18 (60.0%) patients, followed by rheumatoid arthritis factor in 15 (50%) patients. Conclusions: High female predominance along with distinct imaging, histologic and serological characteristic features are seen in patients with IPAF as compared to those with IIP. Further studies in patients with IPAF are needed to understand the natural history and its management.

Background: Neurocognitive decline and depression are the most common unaddressed but noticeable adverse consequences linked with obstructive sleep apnea (OSA) which can affect work performance, social functioning, and quality of life. It is significant to explore both cognition and mood disorders in OSA, as there is adequate evidence in the literature supporting the efficacy of continuous positive airway pressure (CPAP) in the management. Aims and Objectives: The aim was to assess the neurocognitive profile and depression in patients with OSA in our center. Patients and Methods: This was a cross-sectional observational study conducted in a tertiary care center between January 2017 and January 2018. A total of 92 patients with an established diagnosis of OSA (by polysomnography) were included in the study. All patients were given questionnaires for the assessment of neurocognitive function and depression scoring. Results: Out of 92 OSA patients, 29 (31.5%) had normal cognition, 43 (46.7%) had mild cognitive impairment (CI), and 20 (21.7%) had major CI. Out of twenty patients with major CI, major attention deficit was observed in 17 (85%), memory impairment in 16 (80%), verbal fluency was affected in 13 (65%), deficit in language skills was observed in 7 (35%), and visuospatial abilities were affected in 17 patients (85%). Out of 92 OSA patients, 21 (22.8%) had depression and 71.4% of them were females. Conclusions: OSA is an independent risk factor for both depression and neurocognitive decline. It is highly recommended that patients with OSA should be screened for both, so as to provide better clinical outcomes.
