RESUMO

Chronic obstructive pulmonary disease (COPD) patients often experience acute exacerbations requiring hospitalization. Recently, attention has focused on Aspergillus sensitization in the airways of these COPD patients. This study aimed to assess the prevalence of chronic pulmonary aspergillosis (CPA) in COPD patients with acute exacerbations and identify associated risk factors. A cross-sectional descriptive study was conducted at the Jawaharlal Institute of Postgraduate Medical Education and Research from January 2021 to June 2022. Sixty-one COPD patients presenting with acute exacerbations were included. Demographic details, blood investigations, and sputum examinations were performed for all patients. A high-resolution computed tomography thorax was conducted for eligible patients. The prevalence of CPA among patients with an acute exacerbation of COPD was found to be 9.8%, with chronic cavitary pulmonary aspergillosis being the most common presentation (50%). Among post-tubercular COPD patients, the prevalence of CPA was significantly higher at 22.7%. Hemoptysis (p<0.001) and a previous history of tuberculosis (p=0.008) were associated with Aspergillus sensitization. This study highlights the substantial prevalence of CPA in COPD patients with acute exacerbations, particularly in those with a history of tuberculosis. Early recognition and targeted management of CPA in COPD patients may improve outcomes and reduce hospitalization rates. Further large-scale multi-center studies are needed to validate these findings and comprehensively address the impact of CPA on all COPD patients.

RESUMO

Background Chest X-rays (CXRs) are widely used for cost-effective screening of active pulmonary tuberculosis despite their limitations in sensitivity and specificity when interpreted by clinicians or radiologists. To address this issue, computer-aided detection (CAD) algorithms, particularly deep learning architectures based on convolution, have been developed to automate the analysis of radiography imaging. Deep learning algorithms have shown promise in accurately classifying lung abnormalities using chest X-ray images. In this study, we utilized the EfficientNet B4 model, which was pre-trained on ImageNet with 380x380 input dimensions, using its weights for transfer learning, and was modified with a series of components including global average pooling, batch normalization, dropout, and a classifier with 12 image-wise and 44 segment-wise lung zone evaluation classes using sigmoid activation. Objectives Assess the clinical usefulness of our previously created EfficientNet B4 model in identifying lung zone-specific abnormalities related to active tuberculosis through an observer performance test involving a skilled clinician operating in tuberculosis-specific environments. Methods The ground truth was established by a radiologist who examined all sample CXRs to identify lung zone-wise abnormalities. An expert clinician working in tuberculosis-specific settings independently reviewed the same CXR with blinded access to the ground truth. Simultaneously, the CXRs were classified using the EfficientNet B4 model. The clinician's assessments were then compared with the model's predictions, and the agreement between the two was measured using the kappa coefficient, evaluating the model's performance in classifying active tuberculosis manifestations across lung zones. Results The results show a strong agreement (Kappa ≥0.81) seen for lung zone-wise abnormalities of pneumothorax, mediastinal shift, emphysema, fibrosis, calcifications, pleural effusion, and cavity. Substantial agreement (Kappa = 0.61-0.80) for cavity, mediastinal shift, volume loss, and collapsed lungs. The Kappa score for lung zone-wise abnormalities is moderate (0.41-0.60) for 39% of cases. In image-wise agreement, the EfficientNet B4 model's performance ranges from moderate to almost perfect across categories, while in lung zone-wise agreement, it varies from fair to almost perfect. The results show strong agreement between the EfficientNet B4 model and the human reader in detecting lung zone-wise and image-wise manifestations. Conclusion The clinical utility of the EfficientNet B4 models to detect the abnormalities can aid clinicians in primary care settings for screening and triaging tuberculosis where resources are constrained or overburdened.

RESUMO

Background: Lung cancer is the most common malignancy in both gender. Early diagnosis is needed to reduce morbidity and mortality. There is a debate about the most accurate investigating modality for the diagnosis of lung cancer. Methods: It is a retrospective cohort analysis to determine whether an approach of combined contrast-enhanced computed tomography (CECT) thorax with bronchoscopy method has higher sensitivity and specificity than combined CECT thorax with sputum cytology method. Records of patients with lung cancer who had visited the hospital within the last 6 months were retrospectively analyzed for their diagnostic modality. SPSS version 19 software was used for statistical analysis of the data. CECT scan thorax, bronchoscopy, and sputum cytology for lung cancer patients were analyzed. The CECT thorax plus bronchoscopy method was compared with the CECT thorax plus sputum cytology method. Their sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in diagnosing lung cancer were analyzed. Results: Sixty-two patients were considered, including 62.9% males with a mean age of 55.5 years. In patients diagnosed with lung cancer, CECT thorax combined with bronchoscopy method was found to have a sensitivity of 96.67% than CECT thorax combined with sputum cytology method with a sensitivity of 90% and the difference in sensitivity between all individual approaches as well as the combined method was statistically significant with a P = 0.00001 and Chi-square value of 86.5909 owing to the low sensitivity of sputum cytology. CECT thorax combined with sputum cytology approach had a better specificity than CECT thorax combined with bronchoscopy. Conclusion: Combined CECT thorax with sputum cytology method has a better specificity in diagnosing lung cancer than combined CECT thorax with bronchoscopy method.

RESUMO

We describe the case of a 61-year-old diabetic man affected by Achromobacter denitrificans. He was immunocompetent and did not have any past history of chronic lung disease. The patient was treated with sensitive antibiotic meropenem 1 g three times daily. To our knowledge, only one case of A. denitrificans pneumonia has been reported from the Indian subcontinent, in an individual with underlying lung disease, and none in a healthy person.

RESUMO

Background On December 21, 2019, a pneumonia-like outbreak of an unknown cause or origin was found to be emerging in Wuhan, China. In India, the first case of COVID-19 was found in Kerala and then started to spread all over India. Most of the infected people have recovered from the disease, but some patients were found to have symptoms at post-discharge follow-up. Although there are many studies on COVID-19 symptoms and signs during hospital stays, there is a scarcity of information regarding post-COVID-19 manifestations. The purpose of this study is to analyze the clinical characteristics of post-COVID-19 symptoms in patients attending the post-COVID-19 clinics. Methods A descriptive study was started on August 2021 at a tertiary care hospital in Southern India after institutional research and ethics committee clearance. All patients attending the post-COVID clinic, who tested positive for COVID-19 (RT-PCR or rapid antigen test (RAT) diagnosed or radiographically diagnosed COVID-19 (COVID-19 Reporting and Data System [CO-RADS] 5) were recruited. The proportion of people developing post-COVID-19 manifestations and categorization of symptoms in post-COVID-19 and its relationship to the severity of COVID-19 infections and the differences in post-COVID symptoms between hospitalized and non-hospitalized patients were studied. Results We enrolled 227 post-COVID patients who presented to the post-COVID clinic. The median age (IQR) of the participant was 52 (38-59) years, and the male-to-female ratio was 126/101 (1.24). Among 227 patients, 164 (72%) patients had exertional dyspnea, 109 (48%) patients had cough with expectoration, 96 (42.2%) patients with fatigue, 28 (12.33%) patients had myalgia, 18 (7.92) patients had a fever, 12 (5.28%) patients had hair loss, and 30 (13%) had other issues (loss of smell, sleep disturbances, and headache). Among 227, 142 (62.5%) patients were admitted to the hospital for acute COVID-19, and 85 (37.4) patients were in home isolation, but no statistical significance was found between in symptoms. Conclusion From this descriptive study, a high prevalence of post-COVID symptoms was noted, such aslike post-SARS syndrome. Mostly, researchers and clinicians have focused on acute COVID-19, but long-term follow-up with multidisciplinary evaluation and treatment is needed in all patients who recovered from acute COVID-19.

RESUMO

Background: Poor ventilation in healthcare settings is a concern for airborne infections, particularly in light of the potential for coronavirus disease 2019 (COVID-19) transmission. This study aimed to assess the implementation status of airborne infection control (AIC) measures in primary and secondary public healthcare facilities (HCFs) and to explore the facilitating factors and barriers in the implementation of AIC measures. Methods: A mixed-methods approach was adopted, which includes a cross-sectional descriptive study using a checklist to collect data on the implementation of AIC measures in 22 primary and two secondary public HCFs in Puducherry, South India, between October 2020 and February 2021. Further, key informant interviews (KIIs) were conducted among medical officers (MOs). The qualitative data were manually analyzed, and transcripts created from handwritten notes and audio recordings were deductively evaluated. Results: Of the twenty-four health facilities visited, 54.2% had infection control (IC) committees. Annual IC training was held for housekeeping staff, MOs, nurses, and laboratory technicians in 23 (95.8%), 21 (87.5%), 20 (83.4%), and 14 (58.4%) facilities, respectively. Respiratory symptomatic patients were counseled on cough etiquettes in 22 (91.6%) facilities. Adequate cross-ventilation was present in outpatient departments in 16 (66.6%) institutions. N95 masks and face shields were provided in 21 (87.5%) facilities. Training through the KAYAKALP program and the presence of a separate sputum collection area were facilitators of IC, while lack of patient adherence and delays in fund release were found as barriers. Conclusion: Overall, the AIC measures were well-implemented, but improvements are needed in infrastructure development for patient segregation in outpatient departments and dedicated AIC training for all healthcare personnel.

RESUMO

Background: Health care workers (HCWs) are at risk of acquiring tuberculosis (TB) infection and disease due to occupational exposure. But there are no national guidelines on routine screening for TB (active case finding (ACF)) among HCWs and understand its implementation and feasibility. Methods: This study was conducted among HCWs in a teaching hospital in India. We used symptom screening to identify those with presumptive TB and were further evaluated for diagnosis of TB. Results: A total of 1,001 HCWs were screened over a period of 18 months. In our study, 51 (5.1%) HCWs were found to have presumptive TB and on further evaluation, 5 (0.5%) of these patients were diagnosed with active TB. The number needed to screen (NNS) for one active TB among the HCWs was 200. Alcohol use was significantly associated with both presumptive TB (P = 0.037) and active TB (P = 0.035) among HCWs, and exposure to active TB patients (P = 0.014) in the family and workplace and increased frequency of exposures (P = <0.001) were associated with presumptive TB. Conclusion: ACF for TB among HCWs had a good yield in our study. ACF utilizing routine national TB program guidelines is feasible to be implemented among HCWs to aid in the early diagnosis and treatment of TB in this high-risk group.

RESUMO

Chest X-rays are the most economically viable diagnostic imaging test for active pulmonary tuberculosis screening despite the high sensitivity and low specificity when interpreted by clinicians or radiologists. Computer aided detection (CAD) algorithms, especially convolution based deep learning architecture, have been proposed to facilitate the automation of radiography imaging modalities. Deep learning algorithms have found success in classifying various abnormalities in lung using chest X-ray. We fine-tuned, validated and tested EfficientNetB4 architecture and utilized the transfer learning methodology for multilabel approach to detect lung zone wise and image wise manifestations of active pulmonary tuberculosis using chest X-ray. We used Area Under Receiver Operating Characteristic (AUC), sensitivity and specificity along with 95% confidence interval as model evaluation metrics. We also utilized the visualisation capabilities of convolutional neural networks (CNN), Gradient-weighted Class Activation Mapping (Grad-CAM) as post-hoc attention method to investigate the model and visualisation of Tuberculosis abnormalities and discuss them from radiological perspectives. EfficientNetB4 trained network achieved remarkable AUC, sensitivity and specificity of various pulmonary tuberculosis manifestations in intramural test set and external test set from different geographical region. The grad-CAM visualisations and their ability to localize the abnormalities can aid the clinicians at primary care settings for screening and triaging of tuberculosis where resources are constrained or overburdened.

RESUMO

INTRODUCTION: Kikuchi-Fujimoto disease is a benign and self-limiting systemic disorder of unknown aetiology characterised by fever, superficial lymphadenopathy and leukopenia. In highly endemic & low-resource country like India, it is frequently misdiagnosed as tuberculosis. CASE REPORT: Both the cases were diagnosed as necrotizing lymphadenitis by fine-needle aspiration cytology. Tuberculin skin prick test (TST) was positive for one case and negative for the other case. Cartridge based nucleic acid amplification test (CBNAAT) from lymph node aspirate was negative for mycobacterium tuberculosis in both the cases, later on histopathology of lymph node showed diagnosis of Kikuchi-Fujimoto disease. CONCLUSION: Kikuchi Fujimoto is a self-limiting disease systemic disease of unknown aetiology. A definite diagnosis can be established by incisional/excisional biopsy of the lymph node. When dealing with cases of tubercular lymphadenitis, Kikuchi-Fujimoto disease should be kept as differential diagnosis.

RESUMO

Tuberculosis (TB) constitutes a significant burden of infectious diseases worldwide. TB and human immunodeficiency virus (HIV) coinfection potentiate each other, which has a negative impact on the disease progression. Aspergillus colonizing a preexisting parenchymal tubercular cavity is referred to as aspergilloma. Aspergilloma occurring in a patient with active TB is unusual. We report the case of a 50-year-old male who presented to us with complaints of cough and recurrent hemoptysis for 3 months. Clinical and radiological examination revealed right upper lobe aspergilloma. A right upper lobectomy was done and a histopathological examination showed evidence of active TB. The patient was started on antitubercular therapy (ATT) followed by antiretroviral therapy (ART). The presence of active TB should not be overlooked in a patient with aspergilloma, especially in immune-compromised individuals such as people living with HIV, as definitive treatment with surgical resection, and ATT along with ART has better outcomes.

RESUMO

Objective Patients with chronic respiratory diseases (CRD) like asthma and chronic obstructive pulmonary disease (COPD) experience significant morbidity and mortality. The patient's quality of life deteriorates with the progression of the disease. Pharmacological treatment focuses on reducing the symptoms. The psychological impact of the disease on the patient's quality of life is not assessed by all healthcare providers. There is limited knowledge about the patient's demographic and clinical factors affecting the quality of life in CRD patients and aspects hindering or influencing the management of disease in this population. Hence we aimed to conduct a qualitative study on patients with asthma or COPD to get a view of their knowledge about the disease, the problems they encounter in their day-to-day life and the treatment. Methods Semi-structured, face-to-face interviews were conducted by the investigator in the hospital during the patient's follow-up visits. The questions focused on the patient's awareness of the disease, living with chronic respiratory disease, understanding of disease and treatment, and compliance with inhaled therapy. The interviews were audio recorded and transcribed verbatim. Content analysis of the data was done manually. Codes and themes were derived manually. Themes were formed from the codes and sub-themes. Results Five themes were generated from the data obtained: (1) misconceptions regarding the contagious nature of the disease; (2) psychological stress due to feelings of worthlessness, helplessness due to inability to work and poor understanding among family members; (3) inappropriate lifestyle modifications like avoiding fruits and vegetables due to the fear of acute attacks; (4) poor adherence to inhalers due to work timing and difficulty travelling; and (5) lack of reinforcement by the healthcare providers on inhaler technique and adherence were identified as causes of poor inhaler technique and inappropriate knowledge about drugs. Conclusion Subjective reporting by patients in this study was helpful in understanding issues concerning disease management in CRD patients. Apart from assessing the patients' symptoms and prescribing drugs, healthcare providers should take time to impart knowledge about the disease to patients. Though patient education and psychological intervention are challenging to implement daily, they are supplemental to the pharmacologic management of the disease.

RESUMO

Primary pulmonary lymphoma (PPL) is a rare clonal proliferation of lymphoid tissue involving one or both lungs. It is of two types, B-cell and T-cell lymphomas among which T-cell lymphoma is a rare entity and it is sparsely considered as a differential diagnosis in neoplastic lesions of the lung. Here, we are reporting a case of primary pulmonary T-cell lymphoma. PPL is a rare disease and can present with nonspecific symptoms. Radiologically, it can easily be confused with more common malignancies such as bronchogenic carcinoma with or without metastases. PPL carries different therapeutic and prognostic implications. Therefore, physicians should make every effort to achieve histopathological diagnosis before prognosticating a patient presenting with lung cancer.

RESUMO

Background The aim of this study is to assess the prevalence of metabolic syndrome in tuberculosis-associated obstructive airway disease (TOPD) patients, as well as the association of its components with the severity of airflow obstruction. Methodology In this cross-sectional analytical study, we evaluated the clinical profile, spirometry, waist circumference, blood pressure, lipid profile, fasting plasma glucose, and the association of each component with the severity of airflow obstruction. Results The prevalence of metabolic syndrome in TOPD was found to be was 25.77% (95% confidence interval = 18.11-35.28) among study participants. Reduced high-density lipoprotein was the deranged component and was associated with increased severity in Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage II compared to GOLD stage IV. Conclusions The prevalence of metabolic syndrome in TOPD has a severe impact on patients' treatment, outcomes, and complications. However, in our study, tuberculosis-associated metabolic syndrome was the same as the general population. Low high-density lipoprotein levels were associated with the severity of the airflow obstruction.

RESUMO

Context: After completion of treatment, a proportion of pulmonary tuberculosis (TB) (PTB) patients experience lung function impairment (LFI) which can influence their quality of life. Aim: This study was aimed to determine the prevalence of LFI in patients treated for PTB and the associated factors. Settings and Design: A cross-sectional study was conducted among patients treated for PTB in eight primary health centers in Puducherry. Subjects and Methods: The study was carried out among 118 patients. Those aged 18 and above whose PTB treatment outcomes were declared as cured or completed between 2018 and 2019 were included. Demographic data, respiratory symptoms before TB diagnosis, comorbidities, and chest radiography findings before TB treatment were collected. All participants underwent spirometric tests before and after dilatation with salbutamol nebulization. Statistical Analysis: Multivariable analysis identified smear-negative TB and indoor exposure to biomass for cooking as significant independent risk factors for LFI. Results: Of 118 participants interviewed, 70.3% were male and the median age of the participants was 47.7 years. The prevalence of LFI was 62.7% (95% confidence interval: 53.3-71.4). Conclusion: LFI was frequent in patients treated previously for TB. Creating awareness about the possible LFI among these patients along with the awareness for seeking health care for this condition is the need of the hour.

RESUMO

Background Adverse drug reactions (ADRs) to tuberculosis (TB) drugs are a significant concern for medical professionals and health authorities. Adverse events due to drug-resistant TB (DRTB) treatment are among the most important reasons for treatment interruption. Methods This study was an observational study conducted among patients diagnosed with TB (pulmonary/extrapulmonary) receiving antitubercular therapy (ATT) (first line/second-line drugs) irrespective of their age and gender. The patients who consented to participate, registered under National Tuberculosis Elimination Program (NTEP), Puducherry, during the study period from March 2020 to December 2020, were included in the study. The demographic details were recorded from the treatment card, and the participants were provided a diary to note down the adverse events. They were asked to report over the phone or during their visits to treatment centers for the first two months. During the follow-up (irrespective of their treatment phase [intensive/continuation]), the patients were assessed for symptoms and signs of common adverse events. Any adverse events reported by the patient were also recorded and analyzed for causality and severity. Results During the study period, 219 patients were included, of which 92 patients (42%) presented with adverse events. Among the patients with ADRs, 56.5% were males and 43.5% were females. The females were found to be at more risk than males for adverse events with the OR 1.871 (95% CI: 1.066-3.284). GI system was the most common body system involved (39%), followed by musculoskeletal system and skin disorders (24% and 21%), respectively. Most of the adverse events were latent in nature (60.9%), followed by sub-acute onset (28.3%) and acute events (6.5%). Maximum adverse events reported were mild to moderate (71.8%), followed by severe (18.5%). Most of the events were probable in nature (41.3%), and the definite category was 25% as per Naranjo's probability scale. Conclusion The current study shows the frequency of adverse events in patients receiving antitubercular drug therapy. The females were found to be at more risk than males for adverse events. It was found that the GI system was most affected as a known reaction to TB therapy followed by the musculoskeletal system. With more effective pharmacovigilance measures implementation, the adverse events being one of the factors for treatment interruption can be overcome.

RESUMO

Lung cancer is one of the most common cancers and an important cause of cancer-related mortality. Recent advances in targeted therapy and immunotherapy have improved outcomes, but these have limited penetration in resource-constrained situations. We report the real-world experience in treating patients with lung cancer in India. A retrospective analysis of baseline characters, treatment and outcomes of patients with lung cancer seen between January 2015 to December 2018 ( n = 302) at our center was carried out. Survival data were censored on July 31, 2019. A total of 302 patients (median age: 57 years [range, 23-84 years]; males [ n = 203; 67.2%]) were registered. Adenocarcinoma was the most common histology ( n = 225, 75%). The testing rate of epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) mutation analysis in stage IV adenocarcinoma ( n = 191) was 67% and 63%, respectively. Systemic therapy (chemotherapy/gefitinib) was started after a median of 62 days (range, 1-748) from presentation and 38 days (range, 1-219 days) from diagnosis. The median progression-free survival (PFS) and overall survival (OS) were 4.3 months (95% CI, 3.2-5.4) and 9.0 months (95% CI, 7.6-10.5), respectively in the 141 patient without targetable mutations who started palliative chemotherapy. Of the 58 patients who tested positive for EGFR mutation, 41 (71%) started an EGFR tyrosine kinase inhibitor (TKI), and the median PFS and OS in these patients were 8.5 months (95% CI, 5.6-11.4) and 18.4 months (95% CI, 12.2-24.6), respectively. Only 1 out of 10 patients with stage IV ALK -positive adenocarcinoma was started on ALK inhibitor. On multivariate analysis of OS for patients who started on palliative chemotherapy, response to first-line treatment, long distance from the center, use of second line therapy, and a delay of > 40 days from diagnosis to treatment predicted improved survival. Despite providing free diagnostic and treatment services, there was considerable delay in therapy initiation, and a significant proportion of treatment noninitiation and abandonment. Measures should be taken to understand and address the causes of these issues to realize the benefits of newer therapies The apparent paradox of improved survival in those with long delay in initiation of treatment could be explained based on a less aggressive disease biology.

RESUMO

Co-infections or consecutive infections of mucormycosis and aspergillosis are very rare. Additionally, distinguishing between these two infections is also difficult as both these conditions have similar clinical features. We report two similar cases from Tamilnadu, who presented to a tertiary care centre in Puducherry, India in 2017 (first case) and 2019 (second case). The first case was a 70-year-old, non-diabetic male patient who presented with haemoptysis with a prior history of pulmonary tuberculosis. Computed tomography bronchial angiography revealed an air-crescent sign and the histopathological examination showed a fungal ball (aspergillus and mucor) in the right upper lobe and foci of fungal infection in the middle lobe. The second case was a 65-year-old diabetic male patient who presented with blackish expectoration and haemoptysis. A high-resolution computed tomography scan showed a reverse-halo sign in the right upper lobe. The results of the bronchoscopy-guided biopsy were consistent with a diagnosis of mixed mucormycosis and aspergillosis with angioinvasion. Both patients responded to amphotericin B with surgical excision of the affected lobe in the first case. A high degree of clinical suspicion, early surgical intervention and antifungal therapy are essential in the treatment of this rare co-infection.

RESUMO

Melioidosis is caused by an environmental Gram-negative bacilli Burkholderia pseudomallei. Diabetes mellitus, occupational exposure to soil and water, pre-existing renal diseases and thalassemia are significant independent risk factors for melioidosis. A 30-year-old male carpenter and smoker had a history of accidental aspiration of foreign body 2 months prior. On presentation, he had cough with expectoration and low-grade intermittent fever for 1 month. His chest x-ray displayed left lower zone consolidation with cavitation and presence of foreign body in the left lower lobe bronchus. Bronchoalveolar lavage inoculated onto 5% sheep blood agar and MacConkey agar grew B. pseudomallei. Melioidosis due to foreign body aspiration is rare. To the best of our knowledge, there have not been reports of melioidosis infection associated with foreign body inhalation. Hence, pulmonary melioidosis can be considered as a differential diagnosis in cases of foreign body with secondary infection even in immunocompetent host.

RESUMO

Schwannomas are the most common tumor of peripheral nerves. It comprises 1 to 2% of total thoracic tumor. Posterior mediastinum is the most common site in thorax. Hereby we are reporting two cases of schwannoma with different sites of origin. The classical presentation of schwannoma is an asymptomatic mass found on chest radiograph. This tumor is usually benign and slow growing. Imaging followed by histopathological examination is key to the diagnosis of this neoplasm. Resection of tumor cures the disease.

RESUMO

Introduction Prevalence of systemic sclerosis (SSc)-related organ injury is difficult to estimate as it occurs early in SSc, even though patients are often asymptomatic. As the patients with organ damage have a poor prognosis, all the patients should be carefully evaluated and followed­up in the initial periods. This facilitates the early identification and initiation of appropriate therapy. This study emphasizes on different clinical manifestations and early predictors of lung involvement by using clinical, radiological, and pulmonary function tests in a tertiary care centre.   Materials and methods A total of 53 SSc cases, who satisfied American College of Rheumatology (ACR) 2013 criteria, without any overlap syndromes were included in the study. All patients underwent thorough clinical examination along with Modified Rodnan Scoring (MRS) assessment, nailfold capillaroscopy (NFC), chest X-ray (CXR), HRCT thorax, 2D-echocardiography, spirometry and diffusion lung study by carbon monoxide (DLco). Results Out of 53 patients, four were male and 49 were female. Twenty-one patients had limited SSc (lcSSc) and 32 had diffuse SSc (dcSSc). Eighty-three per cent of subjects presented with skin manifestations and 34% with respiratory complaints. Reticulonodular opacities and ground glassing were the predominant radiological abnormalities suggestive of non-specific interstitial pneumonia (NSIP) followed by usual interstitial pneumonia (UIP). Pulmonary hypertension was predominant in patients with lcSSc. Thirty-eight patients had a restrictive pattern of spirometry. Forty-four patients showed deranged DLco, among which two patients showed an isolated decrease in DLco. Thirty-seven patients had abnormal NFC among which dropout pattern was predominant. MRS was significantly correlated with pulmonary involvement by DLco and HRCT. Conclusions SSc can affect the lungs even before developing obvious clinical pulmonary manifestations. DLco and HRCT play a critical role in detecting early lung involvement and predicting the outcomes in SSc. Higher modified Rodnan's score, which has a significant correlation with DLco and HRCT can be used to predict early visceral involvement in resource-limited settings.
