RESUMO
INTRODUCTION: In Pakistan, chronic respiratory conditions contribute a large burden of morbidity and mortality. A major reason for this is the lack of availability of local evidence-based clinical practice guidelines (EBCPGs) in Pakistan, particularly at the primary care level. Thus, we developed EBCPGs and created clinical diagnosis and referral pathways for the primary care management of chronic respiratory conditions in Pakistan. METHODS: The source guidelines were selected by two local expert pulmonologists after a thorough literature review on PubMed and Google Scholar from 2010 to December 2021. The source guidelines covered idiopathic pulmonary fibrosis, asthma, chronic obstructive pulmonary disorders, and bronchiectasis. The GRADE-ADOLOPMENT process consists of three key elements: adoption (using recommendations as is or with minor changes), adaptation (effective context-specific changes to recommendations) or additions (including new recommendations to fill a gap in the EBCPG). We employed the GRADE-ADOLOPMENT process to adopt, adapt, adopt with minor changes, or exclude recommendations from a source guideline. Additional recommendations were added to the clinical pathways based on a best-evidence review process. RESULTS: 46 recommendations were excluded mainly due to the unavailability of recommended management in Pakistan and scope beyond the practice of general physicians. Clinical diagnosis and referral pathways were designed for the four chronic respiratory conditions, explicitly delineating the role of primary care practitioners in the diagnosis, basic management, and timely referral of patients. Across the four conditions, 18 recommendations were added (seven for IPF, three for bronchiectasis, four for COPD, and four for asthma). CONCLUSION: The widespread use of the newly created EBCPGs and clinical pathways in the primary healthcare system of Pakistan can help alleviate the morbidity and mortality related to chronic respiratory conditions disease in the country.

The COVID-19 pandemic has led to mortality and morbidity since December 2019. Many possible treatment options have been advised till date. The role of ivermectin in the treatment of COVID-19 disease remains controversial. The aim of our study was to evaluate the effect of ivermectin in hospitalized patients with non-severe and severe COVID-19 disease. We conducted a retrospective cohort study that compared outcomes in 2 groups of COVID-19 patients hospitalized at the largest tertiary care center of Pakistan. The study group was given ivermectin along with standard treatment of covid-19 disease; the comparison group was not. Data on mortality, inflammatory markers such as C-reactive protein (CRP) and ferritin, length of hospital stay and baseline characteristics were collected from Aga Khan University's database from October 2020 till February 2021. Statistical analysis was done to determine the effectiveness of ivermectin in non-severe and severe COVID-19. Comparison of effectiveness of Ivermectin in both the genders was also conducted. The cohort included 188 patients out of which 90 were treated with ivermectin. Mortality and length of hospitalization was not found to be significantly different in the study group compared with the control group (5.6% vs 5.1%; p=0.87 and 5 days vs 4 days; p=0.27). Analysis of secondary outcomes did not yield statistically significant results, apart from ferritin levels which were significantly less in patients treated with ivermectin (547.1 vs 756.7; p=0.03). The ferritin and CRP levels in affected males were higher than in females on admission and discharge. Our findings suggest ivermectin does not significantly affect all-cause mortality, length of hospitalization and CRP levels in hospitalized COVID-19 patients. Large scale randomized controlled trials (RCTs) are required to further evaluate the role of ivermectin in covid-19 disease.

The long-term sequelae of COVID-19 have now become more common and appreciable. The SARS-CoV-2 virus can cause a variety of infectious and non-infectious pulmonary complications. The purpose of this study is to raise awareness about post-COVID-19 pulmonary sequelae, both infectious and non-infectious, in this geographical area. A retrospective study was conducted from July 1st 2020 to December 20th 2020. A total of 1200 patients were evaluated, with 83 suffering from post-COVID-19 pulmonary complications. The patients' mean age was 62 years (IQR 55-69), with 63 (75.9%) being male. The most common co-morbid illnesses were hypertension (49, 59%) and diabetes (45, 54.2%). The majority of them (37, 44.6%) had severe COVID-19, followed by critical COVID-19 (33, 39.8%). There was no statistically significant difference in recurrence of respiratory symptoms or duration of current illness between non-severe, severe, and critical COVID-19 patients. Non-infectious complications were observed in the majority of patients (n=76, 91.5%), including organizing pneumonia/ground glass opacities in 71 (88%) patients, fibrosis in 44 (55%), pulmonary embolism in 10 (12.5%), pneumomediastinum in 6 (7.4%) and pneumothorax in 7 (8.6%). Infective complications (25, 30.1%) included aspergillus infection in 10 (12.0%) and bacterial infection in 5 (8.47%), with more gram-negative infections and one patient developing Mycobacterium tuberculosis. Post COVID-19 mortality was 11 (13.3%). The long-term pulmonary sequelae of COVID-19 are not rare. Cryptogenic organizing pneumonia, ground glass opacities, and fibrosis were common post-COVID-19 sequelae in our patients. This necessitates frequent close monitoring of these patients in order to initiate early appropriate management and prevent further morbidity and eventual mortality.

INTRODUCTION: Inappropriate use of abbreviations and acronyms in healthcare has become an international patient safety issue. The aim of this study was to assess the knowledge of medical abbreviations and acronyms among residents of the department of medicine at a tertiary-care hospital. METHODS: Internal medicine residents (IMRs), subspecialty residents (SRs) and students were asked to complete a self-administered questionnaire which comprised standard abbreviations used in medicine and its various subspecialties. Scores obtained by the residents were classified into three categories: >70% correct answers; 50-69% correct answers; <50% correct answers. RESULTS: A total of 77 IMRs, SRs and medical students participated. Overall, good responses were achieved by 53 (68.8%), 16 (20.8%) attained satisfactory responses, and eight (10.4%) had unsatisfactory scores. The majority of SRs achieved good responses (19/22 (86%)), followed by IMRs (30/40 (75%)) and students (4/15 (26.7%)). Evaluation of their knowledge taken from the list of 'do not use' abbreviations showed that 89.6% reported using 'Q.D.' instead of 'once a day', and 93% used 'IU' instead of the entire phrase 'international unit'. The top five 'not to use' abbreviations were ZnSO4, µg, MgSO4, IU and SC, with the frequency 100%, 96%, 94.8%, 93% and 90%, respectively. CONCLUSIONS: This study showed that there is a knowledge gap among trainees in medicine regarding the meaning and usage of common medical abbreviations. We therefore recommend proper education of trainees in medicine to ensure they understand the meaning of abbreviations and are aware of the list of 'do not use' abbreviations.

OBJECTIVE: To evaluate the clinical course and outcomes in patients with acute severe asthma in a tertiary care setting. METHODS: The retrospective cross-sectional study was conducted at the Aga Khan University Hospital, Karachi, and comprised data of patients of age 16 and above who were admitted with a diagnosis of acute severe asthma from January 2000 to December 2013. These patients had undergone clinical evaluation to assess the severity of illness as well as the complications and eventual outcomes. SPSS 16 was used for statistical analysis. RESULTS: Of the 50 patients in the study, 41 (82%) were females. The overall mean age was 53.1±20.3 years. Ventilator support was required by 37(74%) patients. Presence of acidaemia was associated with the need for invasive ventilation (p<0.033) which in turn was associated with increased hospital stay (p<0.043). Complications were observed in 37(74%) patients, the most common being respiratory failure in 35(70%) and arrhythmias in 8(16%). Use of both non-invasive and invasive ventilation was found to be significantly associated with development of complications (p<0.001 and p<0.009). A total of 4(8%) patients died. Presence of acidaemia was found to be significantly associated with mortality (p<0.032). CONCLUSION: Overt acidaemia at initial presentation in patients with acute severe asthma was significantly associated with higher rates of invasive ventilation leading to increased hospital stay, complications and higher mortality rate.

BACKGROUND: Community Acquired Pneumonia (CAP) is a commonly encountered disease, one third of which is Severe Community Acquired Pneumonia (SCAP) that can be potentially fatal. There is a paucity of data on etiology and outcome of patients with SCAP in South Asian Population. METHODS: A retrospective cross-sectional study was conducted from March 2002 till December 2008 on patients of 16 years and above who were admitted with the diagnosis of SCAP in accordance to the criteria of American Thoracic Society Guidelines (2001). The patients underwent clinical and diagnostic evaluations to detect the severity of illness as well as the etiology and other risk factors influencing the eventual outcome of SCAP. RESULTS: A total of 189 patients were included in the study. The mean age was 60 ± 18.0 years and 110 (58%) patients were males. The most common isolated pathogens were Staphylococcus aureus (15 patients), Streptococcus pneumoniae (14 patients) and Pseudomonas aeruginosa (9 patients). The highest mortality was seen in patients with Pseudomonas aeruginosa (89%) and Staphylococcus aureus (53%). Overall mortality rate was 51%. On univariate analysis, septic shock (p <0.001), prior antibiotic use (p = 0.04), blood urea nitrogen > 30 mg/dl (p = 0.03), hematocrit < 30% (p = 0.03) and Acute Physiology and Chronic Health Evaluation (APACHE) II score > 20 (p < 0.001) were significantly different between the patients who survived as compared to those who did not. On multivariate analysis, septic shock (p <0.001, OR: 4.70; 95% CI= 2.49-8.87) was found to be independently associated with mortality. CONCLUSION: The microbes causing SCAP in our study are different from the usual spectrum. Staphylococcus aureus and Pseudomonas aeruginosa were the common causative pathogens and associated with high mortality. It is important to establish clinical guidelines for managing SCAP according to the etiologic organisms in our setting.

BACKGROUND: Leukotriene receptor antagonists (LTRAs) are well established in the management of outpatient asthma. However, there is very little information as to their role in acute asthma exacerbations. We hypothesized that LTRAs may accelerate lung function recovery when given in an acute exacerbation. METHODS: A randomized, double blind, placebo-controlled trial was conducted at the Aga Khan University Hospital to assess the efficacy of oral montelukast on patients of 16 years of age and above who were hospitalized with acute asthma exacerbation. The patients were given either montelukast or placebo along with standard therapy throughout the hospital stay for acute asthma. Improvements in lung function and duration of hospital stay were monitored. RESULTS: 100 patients were randomized; their mean age was 52 years (SD +/- 18.50). The majority were females (79%) and non-smokers (89%). The mean hospital stay was 3.70 ± 1.93 days with 80% of patients discharged in 3 days. There was no significant difference in clinical symptoms, PEF over the course of hospital stay (p = 0.20 at day 2 and p = 0.47 at day 3) and discharge (p = 0.15), FEV1 at discharge (p = 0.29) or length of hospital stay (p = 0.90) between the two groups. No serious adverse effects were noted during the course of the study. CONCLUSION: Our study suggests that there is no benefit of addition of oral montelukast over conventional treatment in the management of acute asthma attack. TRIAL REGISTRATION NUMBER: 375-Med/ERC-04.

OBJECTIVES: This meta-analysis examined the effect of macrolides on resolution of community-acquired pneumonia (CAP) and interpretation of clinical benefit according to microbiology; emphasis is given to data under-reported countries (URCs). METHODS: This meta-analysis included 47 publications published between 1994 and 2022. Publications were analysed for 30-d mortality (58 759 patients) and resolution of CAP (6465 patients). A separate meta-analysis was done for the prevalence of respiratory pathogens in URCs. RESULTS: Mortality after 30 d was reduced by the addition of macrolides (odds ratio [OR] 0.65, 95% confidence interval [CI] 0.51-0.82). The OR for CAP resolution when macrolides were added to the treatment regimen was 1.23 (95% CI 1.00-1.52). In the CAP resolution analysis, the most prevalent pathogen was Streptococcus pneumoniae (12.68%; 95% CI 9.36-16.95%). Analysis of the pathogen epidemiology from the URCs included 12 publications. The most prevalent pathogens were S. pneumoniae (24.91%) and Klebsiella pneumoniae (12.90%). CONCLUSION: The addition of macrolides to the treatment regimen led to 35% relative decrease of 30-d mortality and to 23% relative increase in resolution of CAP.

OBJECTIVE: To determine the frequency of community-acquired respiratory pathogens with special focus on atypical organisms in patients presenting to a tertiary care facility with community-acquired pneumonia (CAP). METHODS: The descriptive study on adult patients was conducted from February 2007 to March 2008 at the Aga Khan University Hospital, Karachi. It comprised 124 consenting patients of age 16 and above who presentd with a diagnosis of community-acquired pneumonia. The diagnostic modalities used were based on significant changes in antibody titer or persisting high antibody titers in the case of Mycoplasma pneumoniae and Chalmydia pneumoniae infections, or bacterial antigen in urine, in the case of Legionella pneumophila serogroup 1 infection. Pyogenic bacteria were identified on the results of respiratory secretions or blood cultures. Continuous data and categorical variables were worked out using SPSS version 15. RESULTS: Among the 124 patients enrolled, an etiologic agent was identified in 44 (35.4%) patients. The most common organism was Mycoplasma pneumoniae (n = 21, 17%), followed by Chlamydia pneumoniae (n = 15, 12%), Streptococcus pneumoniae (n = 9, 7%), Haemophilus influenzae (n = 2, 1.6%), Klebsiella pneumoniae (n = 2, 1.6%) and Staphylococcus aureus (n = 1, 0.8%). Streptococcus pneumoniae was the most common organism isolated from blood cultures. No cases of Legionella pneumophila serogroup 1 were identified. CONCLUSIONS: Mycoplasma pneumoniae and Chalmydia pneumoniae are significant etiologic agents for community-acquired pneumonia occurring in Karachi. Local treatment guidelines for community-acquired pneumonia should include therapy directed specifically at these agents.

OBJECTIVES: To estimate the frequency of different forms of tobacco intake such as smoker's tobacco, chewable tobacco and snuff tobacco among shisha smoker's and to study the patterns and predictors of shisha smoking affecting youth from different cities of Pakistan. METHODS: A cross-sectional study was conducted including youth from four cities. Participants were asked to fill out a data collection tool at shisha cafes, shopping malls and restaurants. Data was analyzed using SPSSv.18. RESULTS: A total of 406 participants, 296 (73%) males and 110 (27%) females were included in the study. There were 163 (40%) cigarette smokers; 65 (16%) chewed tobacco and 33 (8%) snuffed it. The median age at initiation of Shisha smoking was 20 years. 280 (69%) considered Shisha smoking to be less deleterious to health than cigarettes. Respiratory disease was the most commonly cited health effect reported. Most 248 (61%) of the participants were infrequent shisha smokers. CONCLUSION: There is high frequency of tobacco usage in the form of cigarettes, chewable tobacco and snuff tobacco among shisha smokers of Pakistan. The highest frequency is for cigarette smoking. The rise in Shisha smoking as a trendy social habit appears to be occurring despite emerging scientific evidence of its potential health risks.

BACKGROUND: There remains scarcity of literature regarding the patient's health status post-COVID-19 infection. This study analyzes the prevalence of residual symptoms and quality of life (QoL) after COVID-19. METHODS: An anonymous online survey was administrated in Pakistan from November 2020 to April 2021 in COVID-19 survivors. The questionnaire used the 12-Item Short Form Health Survey (SF-12) to assess mental and physical QoL. Multivariate linear regression was used to explore factors associated with mental and physical QoL scores. RESULTS: A total of 331 COVID-19 survivors participated in our survey. Around 42.0% of the cohort reported within 1-3 months of diagnosis of COVID-19. The common residual symptoms were body aches (39.9%), low mood (32.6%), and cough (30.2%). Better physical QoL was associated with being male (adjusted beta: 3.328) and having no residual symptoms (6.955). However, suffering from nausea/vomiting during initial COVID-19 infection (-4.026), being admitted to the ICU during COVID-19 infection (-9.164), and suffering from residual body aches (-5.209) and low mood (-2.959) was associated with poorer QoL. Better mental QoL was associated with being asymptomatic during initial COVID-19 infection (6.149) and post-COVID (6.685), while experiencing low mood post-COVID was associated with poorer mental QoL (-8.253 [-10.914, -5.592]). CONCLUSION: Despite presumed "recovery" from COVID-19, patients still face a wide range of residual symptoms months after initial infection, which contributes towards poorer QoL. Healthcare professionals must remain alert to the long-lasting effects of COVID-19 infection and aim to address them appropriately to improve patients' QoL.

We report the case of a 60-year-old woman, presenting with left vocal cord paralysis (VCP). Diagnostic evaluation revealed sarcoidosis to be the underlying pathology. Computed tomography (CT) scans exhibited enlarged subcarinal, pretracheal, and prevascular lymph nodes as the possible mechanism of left VCP through compression of the left recurrent laryngeal nerve. Initial treatment with oral prednisolone and azathioprine led to remission of symptoms; however, tapering of dosage led to relapse of cough without any signs of VCP. The dosage of prednisolone was further boosted, leading to complete remission. A review of literature reveals 20 cases have been reported to date, with all but one involving the left vocal cord. This is the first reported case, with a relapse of the disease without a relapse of VCP, indicating the rarity of sarcoidosis-associated VCP.
RESUMO
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected almost every country in the world since De-cember 2019. Despite the efforts of the human race to combat the virus, we are still looking for an evidence-based permanent cure for the disease. Ivermectin has recently emerged as one of the therapies having a beneficial effect on COVID-19. Ivermectin, owing to its properties, continues to be a possible treatment against the COVID-19 disease. Already being a mainstream drug with minimal adverse effects, it garners valid consideration. It's use in hospitalized patients, randomized controlled trials, and observational studies has also supported its implementation. In this article, we have reviewed recent studies and explored the effectiveness of ivermectin in hospitalized COVID-19 patients.

INTRODUCTION: COVID-19-associated pulmonary sequalae have been increasingly reported after recovery from acute infection. Therefore, we aim to explore the charactersitics of persistent lung parenchymal abnormalities in patients with COVID-19. MATERIAL AND METHODS: An observational study was conducted in patients with post-COVID lung parenchymal abnormalities from April till September 2020. Patients ≥18 years of age with COVID-19 who were diagnosed as post-COVID lung parenchymal abnormality based on respiratory symptoms and HRCT chest imaging after the recovery of acute infection. Data was recorded on a structured pro forma, and descriptive analysis was performed using Stata version 12.1. RESULTS: A total of 30 patients with post-COVID lung parenchymal abnormalities were identified. The mean age of patients was 59.1 (SD 12.6), and 27 (90.0%) were males. Four HRCT patterns of lung parenchymal abnormalities were seen; organizing pneumonia in 10 (33.3%), nonspecific interstitial pneumonitis in 17 (56.7%), usual interstitial pneumonitis in 12 (40.0%) and probable usual interstitial pneumonitis in 14 (46.7%). Diffuse involvement was found in 15 (50.0%) patients, while peripheral predominance in 15 (50.0%), and other significant findings were seen in 8 (26.7%) patients. All individuals were treated with corticosteroids. The case fatality rate was 16.7%. Amongst the survivors, 32.0% recovered completely, 36.0% improved, while 32.0% of the patients had static or progressive disease. CONCLUSION: This is the first study from Southeast Asia that identified post-COVID lung parenchymal abnormalities in patients who had no pre-existing lung disease highlighting the importance of timely recognition and treatment of this entity that might lead to fatal outcome.

Introduction Interstitial lung disease (ILD) is a heterogeneous group of over 200 parenchymal lung diseases with a myriad of etiologies. Interstitial lung disease registries from around the world show varying prevalence and incidence of these diseases. The aim of this study was to determine the epidemiology and characteristics of ILD in Pakistan. Methods This web-based registry, which is the first multicenter registry of ILD from Pakistan, recruited patients from 10 centers of five major cities between January 2016 and March 2019. Results A total of 744 patients were enrolled in the registry. The five most frequent ILDs were idiopathic pulmonary fibrosis (IPF) 34.4%, hypersensitivity pneumonitis (HP) - 17.7%, idiopathic nonspecific interstitial pneumonitis (iNSIP) - 16.8%, connective tissue disease-associated ILD (CTD-ILD) - 16.3%, and sarcoidosis - 9.1%. Conclusion Idiopathic pulmonary fibrosis is the most prevalent ILD in Pakistan, followed by HP and iNSIP. An ongoing prospective registry with longitudinal follow-up will help us further elaborate on the clinical characteristics, treatment, and survival outcome of patients with ILD.
RESUMO
Introduction The coronavirus disease 2019 (COVID-19) vaccine is available across various countries worldwide, with public-private partnerships ensuring all individuals are vaccinated through a phased approach. Irrespective of the geographical spread, several myths pertaining to the COVID-19 vaccine have stemmed, ultimately limiting the national administration of vaccines and rollouts. This study assessed the acceptance of the COVID-19 vaccine among the general public in Pakistan. Methods A pre-validated questionnaire was administered from January 2021 to February 2021 to assess the public attitude and acceptance of the COVID-19 vaccine. Logistic regression analyses were run to identify factors associated with the acceptance among the population. Results A total of 936 responses were elicited, where 15% perceived their risk of being infected at 20-30% with an overall 70% agreeing to be vaccinated if recommended. Multivariate analysis identified higher acceptance in the male gender, healthcare workers, and students. Of all, 66% respondents chose healthcare workers and public officials, whereas 15.6% chose scientific literature, and 12.9% chose social media as the most reliable source of COVID-19 information. Conclusion Given the relatively greater trust in healthcare providers for information regarding COVID-19, healthcare workers ought to be on the frontline for vaccine campaigns and public outreach efforts, with governmental efforts in addition to the promotion of scientific materials for population-level understanding.
