Retrospective Analysis of Clinical Characteristics and Outcomes of Pregnant Women with SARS-CoV-2 Infections Admitted to Intensive Care Units in India (Preg-CoV): A Multicenter Study.

Aim: The aim was to examine the outcomes of pregnant women admitted to intensive care unit with coronavirus disease-2019 (COVID-19) infection during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in India. The primary outcome of the study was maternal mortality at day 30. The secondary outcomes were the intensive care unit (ICU) and hospital length of stay, fetal mortality and preterm delivery. Materials and methods: This was a retrospective multicentric cohort study. Ethical clearance was obtained. All pregnant women of the 15-45-year age admitted to ICUs with SARS-CoV-2 infection during 1st March 2020 to 31st October, 2021 were included. Results: Data were collected from nine centers and for 211 obstetric patients admitted to the ICU with a confirmed diagnosis of COVID-19. They were divided in to two groups as per their SpO2 (saturation of peripheral oxygen) level at admission on room air, that is, normal SpO2 group (SpO2 > 90%) and low SpO2 group (SpO2 < 90%). The mean age was (30.06 ± 4.25) years and the gestational age was 36 ± 8 weeks. The maternal mortality rate was10.53%. The rate of fetal death and preterm delivery was 7.17 and 28.22%, respectively. The average ICU and hospital length of stay (LOS) were 6.35 ± 8.56 and 6.78 ± 6.04 days, respectively. The maternal mortality (6.21 vs 43.48%, p < 0.001), preterm delivery (26.55 vs 52.17%, p = 0.011) and fetal death (5.08 vs 26.09%, p = 0.003) were significantly higher in the low SpO2 group. Conclusion: The overall maternal mortality among critically ill pregnant women affected with COVID-19 infection was 10.53%. The rate of preterm birth and fetal death were 28.22 and 7.17%, respectively. These adverse maternal and fetal outcomes were significantly higher in those admitted with low SpO2 (<90%) at admission compared with those with normal SpO2.

Isolated pleural effusion is a rare presentation of ovarian hyperstimulation syndrome following ovulation induction therapy. We hereby report the case of a 24-year-old female who presented with unilateral moderate pleural effusion following ovulation induction therapy. Therapeutic thoracentesis was performed to relieve the breathlessness in this case.

Monitoring whole-lung lavage using lung ultrasound: The changing phases of the lung.

Lung ultrasound (LUS) has been proven to yield valuable information for lung and pleural pathology. It is well validated for assessing extravascular lung water. It can also be used to monitor stages of controlled lung de-aeration in whole lung lavage (WLL) which is the treatment for Pulmonary Alveolar Protienosis (PAP),characterized by abnormal surfactant in the alveoli affecting gas exchange .LUS can help decide the point of termination of lung flooding. A 55 year old lady with biopsy proven pulmonary alveolar proteinosis presented with respiratory failure. WLL was planned. LUS was used to study the stages of lung flooding as previously described for ARDS model.6 areas screened based on six areas that are normally examined like upper zone, mid zone and lower zone showed alveolar interstitial pattern. One lung ventilation (OLV) was done and isolation of lavage lung was confirmed which was seen as lung collapse (lung pulse) on LUS. Saline infusion resulted in increase in B lines followed by tissue like pattern with fluid bronchogram on LUS(alveolar flooding) in all the areas. During the lavage of the second lung, appearance of alveolar flooding pattern resulted in termination of saline infusion. The use of LUS in monitoring WLL reduced amount of saline used for lavage, pick up complications like pleural effusion and spillage.

Effects of oral montelukast on airway function in acute asthma: A randomized trial.

BACKGROUND: The role of leukotriene receptor antagonist is well known in the management of chronic asthma, but their efficacy in acute exacerbation of asthma is unknown. The present study was done to evaluate the clinical efficacy of oral montelukast as an add on therapy to the usual standard therapy of acute attack of bronchial asthma. MATERIALS AND METHODS: A randomized single-blinded controlled study was conducted in a tertiary care teaching hospital. A total of 162 patients with age >18 years of acute exacerbations due to bronchial asthma were included in the study. The patients were randomized into two study and control groups. The study group patients received oral montelukast (10 mg) once daily for 2 weeks, while the control group received a placebo. All the patients received standard therapy according to GINA guidelines. Improvements in lung function tests, clinical symptoms, and relapse rates were monitored at baseline, 1 week, 2 weeks, and 4 weeks. Side effects profile was also monitored. RESULTS: A total of 160 patients were finally assessed. Seventy-eight patients belonged to study group and 82 in the control group. Baseline characteristics were similar and well matched in both groups. Mean age was 39.9 ± 15.8 years in the study group and 42.8 ± 12.8 in the control group and majority were female patients in both groups. At the end of 4 weeks, it was observed that the study group patients who received montelukast had better forced expiratory volume in 1 s (FEV1) improvement by 21% (0.21 L) as compared to the control group (P < 0.0033). It was also observed that there was a better improvement in peak expiratory flow rate (PEFR) at 2 weeks (0.4 L/s, 12%) and at 4 weeks (0.9 L/s, 23%) as compared to the control group (P < 0.0376 and P < 0.0003 respectively). There was no difference in forced vital capacity (FVC), FEV1/FVC ratio and relapse rates between the two groups. No serious adverse effects were observed during the study. CONCLUSIONS: In acute asthma exacerbations, the present study showed that additional administration of oral montelukast resulted in significantly higher FEV1at 4 weeks and PEFR at 2 weeks and 4 weeks as compared to the standard treatment alone. These findings should be confirmed by conducting a larger population-based clinical study.

Drug-induced hepatitis and the risk factors for liver injury in pulmonary tuberculosis patients.

INTRODUCTION: Short-course chemotherapy containing rifampicin and isoniazid in combination has proved to be highly effective in the treatment of tuberculosis, but one of its adverse effects is hepatotoxicity. Various risk factors have been found to be associated with drug-induced liver injury (DILI) in general population. The study aimed to determine the prevalence of drug-induced hepatitis and the risk factors associated with the DILI among the patients of pulmonary tuberculosis in Indian patients. SETTING AND DESIGN: Prospective nested case control study. MATERIALS AND METHODS: Out of the cohort of 3900 tuberculosis patients who were initiated on anti-tubercular therapy, 150 patients who developed drug-induced liver injury due to short-course chemotherapy under RNTCP were included in the analysis. Thirty cases were being followed up in our hospital and other 120 were referred to us for the management of drug-induced hepatitis from the primary health centers. The diagnostic criteria's for DILI were made according to the American Thoracic Society criteria. Analyses of various risk factors were done for the development of DILI. RESULTS: The prevalence of DILI in the present study was 3.8%. It was observed that DILI patients were older and their serum albumin levels were lower, and they had multiple co-morbid conditions. Regular alcohol intake, more extensive disease associated with radiological and female gender were observed to be independent risk factors for the development of DILI. CONCLUSIONS: Of the various risk factors analyzed, advanced age, hypoalbuminemia, regular alcohol intake and advanced nature of the disease were independent risk factors for the development of DILI. The risk of development of hepatitis is increased in the presence of one or more of these risk factors.

Outcomes associated with acute exacerbations of chronic obstructive pulmonary disorder requiring hospitalization.

BACKGROUND: Acute exacerbations of chronic obstructive pulmonary disorder (AECOPD) are known to be associated with increased morbidity and mortality and have a significant socioeconomic impact. The factors that determine frequent hospital readmissions for AECOPD are poorly understood. The present study was done to ascertain failures rates following AECOPD and to evaluate factors associated with frequent readmissions. MATERIALS AND METHODS: We conducted a prospective study among 186 patients with COPD with one or more admissions for acute exacerbations in a tertiary care hospital. Frequency of previous re-admissions for AECOPD in the past year, and clinical characteristics, including spirometry were ascertained in the stable state both before discharge and at 6-month post-discharge. Failure rates following treatment were ascertained during the follow-up period. All the patients were followed up for a period of 2 years after discharge to evaluate re-admissions for the AECOPD. RESULTS: Of 186 COPD patients admitted for AECOPD, 54% had one or more readmission, and another 45% had two or more readmissions over a period of 2 years. There was a high prevalence of current or ex-heavy smokers, associated co-morbidity, underweight patients, low vaccination prevalence and use of domiciliary oxygen therapy among COPD patients. A total of 12% mortality was observed in the present study. Immediate failure rates after first exacerbation was observed to be 34.8%. Multivariate analysis showed that duration >20 years (OR = 0.37; 95% CI: 0.10-0.86), use of Tiotropium (OR = 2.29; 95% CI: 1.12-4.69) and use of co-amoxiclav during first admission (OR = 2.41; 95% CI: 1.21-4.79) were significantly associated with higher immediate failure rates. The multivariate analysis for repeated admissions revealed that disease duration >10 years (OR = 0.50; 95% CI: 0.27-0.93), low usage of inhaled ICS + LABA (OR = 2.21; 95% CI: 1.08-4.54), and MRC dyspnea grade >3 (OR = 2.51; 95% CI: 1.08-5.82) were independently associated with frequent re-admissions for AECOPD. CONCLUSIONS: The outcomes of patients admitted for an acute exacerbation of COPD were poor. The major factors influencing frequency of repeated COPD exacerbations were disease duration, low usage of inhaled ICS + LABA, and MRC dyspnea grade >3.

Role of health education and self-action plan in improving the drug compliance in bronchial asthma.

BACKGROUND: Considering the prevalence and associated burden of disease due to bronchial asthma, it is mandatory to obtain an optimal control of the disease and to improve outcomes for these patients. But it has been observed that there is very poor adherence to the inhalational therapy which leads to the suboptimal control of the disease. OBJECTIVES OF THE STUDY: To study the adherence for aerosol therapy in bronchial asthma patients and to assess the impact of health education and self-action plan in improving the compliance to the therapy. METHODOLOGY: A prospective study was done in a total of 500 bronchial asthma patients over a period of 2 years. Once included in the study, the patients were followed-up for a total of 12 weeks for calculation of nonadherence to the aerosol therapy. In nonadherent patients, we employed various health education strategies to improve the compliance in these cases. RESULTS: A total of 500 patients of bronchial asthma who were started on aerosol therapy over duration of 2 years were included in the study. At the end of 12 weeks, it was observed that, only 193 patients (38.6%) had regular compliance and 307 patients (61.4%) were noncompliant to aerosol therapy as prescribed for bronchial asthma. Factors that were associated with poor compliance were: Lower educational level status, poor socioeconomic status, cumbersome regimens, dislike of medication, and distant pharmacies. Nondrug factors that reduced the compliance were: Fears about side effects, anger about condition or its treatment, forgetfulness or complacency, and patient's ill attitudes toward health. After employing the various strategies for improving the compliance in these patients, the compliance increased in 176 patients (57.3%) among the earlier defaulted patients, while the remaining 131 patients (42.7%) were found to be noncompliant even after various educational techniques. CONCLUSION: Noncompliance in asthma management is a fact of life and no single compliance improving strategy probably will be as effective as a good physician-patient relationship. Optimal self-management allowing for optimization of asthma control by adjustment of medications may be conducted by either self-adjustment with the aid of a written action plan or by regular medical review. Individualized written action plans based on peak expiratory flow are equivalent to action plans based on symptoms.
