Short-acting ß2-agonists over-prescription in patients with asthma: an Indian subset analysis of international SABINA III study.

OBJECTIVE: The SABINA (SABA use IN Asthma) program was initiated to describe short-acting ß2-agonists (SABA) prescription patterns and assess the impact of its over-prescription on exacerbation risk and asthma control. We evaluated SABA prescription patterns in patients with asthma in the Indian cohort of SABINA III. METHODS: This multi-centre, observational, cross-sectional study included retrospective and real-time electronic data collection. Data were extracted from medical records of patients with asthma (aged >12 years) having >3 consultations with the same healthcare practitioners between March 2019 and January 2020. The data included prescriptions of SABA and other asthma treatments and over-the-counter (OTC) purchases of SABA. SABA prescriptions were categorized by the number of SABA canisters prescribed in the 12 months preceding the study visit. RESULTS: A total of 510 patients with asthma were included from specialist care (mean age 49.1 years; 57.65 females), with 8.2% classified with mild asthma and 91.8% with moderate-to-severe asthma. SABA as monotherapy and add-on to maintenance therapy was prescribed to 4.5% (n = 23) and 44.9% (n = 229) of patients, respectively. While ICS monotherapy and ICS/LABA were prescribed to 5.1% (n = 26) and 93.3% (n = 476) of patients, respectively. SABA was found to be over-prescribed (≥3 SABA canisters/year) among 23.9% of patients (n = 122). Additionally, 8% of patients (n = 41) purchased SABA OTC without prescription. CONCLUSIONS: Nearly one-fourth of patients with asthma in India were over-prescribed SABA. Educational programmes targeted at national and regional levels should be expanded to raise greater asthma awareness and encourage the adoption of guideline-directed asthma treatment plans among healthcare practitioners.

Superior vena cava syndrome caused by pulmonary amoebic abscess.

Isolated pulmonary amoebiasis without involvement of liver and other systems is extremely rare. Its presentation with superior vena cava (SVC) syndrome is not well documented. The case of 38-year-old male who developed SVC syndrome due to a large pulmonary amoebic abscess, which initially mimicked a pulmonary neoplasm with distal lung abscess is presented here. Subsequent bacteriological examination of the aspirated pus and the sputum along with suggestive serology confirmed the diagnosis of pulmonary amoebic abscess.

Bilateral spontaneous pneumothorax in silicosis.

Occurrence of pneumothorax in silicosis is rare and when it occurs, pneumothorax is usually unilateral. We report here a patient with accelerated silicosis who presented with bilateral spontaneous pneumothoraces occurring simultaneously. The rarity of its clinical presentation in the form of bilateral simultaneous spontaneous pneumothorax combined with the typical clinical and radiological features of accelerated silicosis with tuberculosis make us to report this case.

Tuberculous oesophagopleural fistula.

Hydropneumothorax complicating to oesophagopleural and broncho-oesophageal fistula is an unusual presentation and is reported in literature as separate clinical entities. Here we present a case of hydropneumothorax with both oesophagopleural and broncho-oesophageal fistula of tuberculous aetiology occurring simultaneously in the same patient. Oesophagopleural fistula was suspected clinically by colour of pleural fluid. Subsequent barium swallow demonstrated leak of contrast material from oesophagus into pleural cavity. Later on, computed tomography of chest with oral contrast confirmed communication of oesophagus with both right pleural cavity and right main bronchus. The fistulous connection between these structures appeared to be due to tuberculous mediastinal lymphadenopathy as evident on CT thorax.

Life-threatening postpartum hemolysis, elevated liver functions tests, low platelets syndrome versus thrombocytopenic purpura - Therapeutic plasma exchange is the answer.

The differential diagnosis of life-threatening microangiopathic disorders in a postpartum female includes severe preeclampsia-eclampsia, hemolysis, elevated liver functions tests, low platelets syndrome and thrombotic thrombocytopenic purpura. There is considerable overlapping in the clinical and laboratory findings between these conditions, and hence an exact diagnosis may not be always possible. However, there is considerable maternal mortality and morbidity associated with these disorders. This case underlines the complexity of pregnancy-related microangiopathies regarding their differential diagnosis, multiple organ dysfunction and role of therapeutic plasma exchange in their management.
