RESUMEN
INTRODUCTION: Interstitial Lung Diseases are the major cause of mortality in Connective Tissue Diseases. OBJECTIVES: Our aim is to describe patients with Interstitial Lung Disease associated with Connective Tissue Diseases (CTD-ILD) in Chest Clinic -Colombo 08. METHODS: We conducted a descriptive cross-sectional study at Central Chest Clinic, Colombo, Sri Lanka and data of all patients attending the clinic during were analysed. RESULTS: The sample consisted of 83 consecutive patients diagnosed with CTD-ILD. The age ranged from 24 to 72 years with mean (SD) age of 55.6 (10.6) years. The majority was female patients (n=70, 88.6%). The majority 53.0% (n=44) had RA and SSc was the second commonest CTD-ILD (n=22, 26.5%). NSIP 51(61.9%) was the most frequently observed HRCT pattern in our cohort whereas UIP was the second commonest. RA-ILD subgroup demonstrated female (n=37, 86.0%) preponderance. NSIP (n=24, 55.8%) was the commonly observed HRCT pattern fallowed by UIP (n=15, 34.9%) pattern. Among RA-ILD patients, 28 (65.1%) had positive Rheumatoid factor. Majority of (n=20, 90.9%) SSc-ILD were females. Sixteen (72.7%) of them had NSIP pattern in HRCT analysis fallowed by UIP (n=6, 27.3%). CONCLUSION: RA-ILD was the most frequent type of CTD-ILD followed by SSc. More importantly; the present study revealed the predominant NSIP pattern and clear female preponderance in RA-ILD compared to global data. We recommend prospective multicenter studies to be carried out and prospective disease registries to be established to explore the epidemiological, clinical, radiological and prognostic characteristics of CTD ILD in Sri Lanka.

BACKGROUND: Infection due to the SARS-CoV-2 virus can have a wide range of presentations from asymptomatic/mildly symptomatic to severe disease with multiorgan failure. Fever is a common symptom. But hyperpyrexia defined as temperature > 41.5 °C is not usual in COVID-19. CASE PRESENTATION: A 24-year-old previously well Sri Lankan female in the 24th week of gestation of her first pregnancy presented with fever and shortness of breath. She was confirmed to have coronavirus disease-2019 (COVID-19). History was suggestive of late presentation on approximately the eighth day of the illness. She had rapidly deteriorating hypoxia due to COVID pneumonia requiring mechanical ventilation two days after the admission. There was evidence of cytokine storm without any secondary bacterial infection. She received glucocorticoids, tocilizumab, and intravenous antibiotics. Although she initially showed mild improvements, she subsequently developed high-grade fever with the axillary temperature rising to 41.7 °C starting from the seventh day of admission. There were no causative medicines or risk factors to explain hyperpyrexia. She died on the ninth day of admission. CONCLUSIONS: There are no reports of patients developing this complication during pregnancy. The pathophysiology of this rare life-threatening complication remains elusive. Detailed reporting and in-depth analysis of such patients will facilitate the understanding of the associations and successful management of these patients.

A 32-year-old patient, who was on treatment for tuberculous meningitis complicated with venous sinus thrombosis, was referred to the medical unit as he developed new onset fever, cough and shortness of breath. He was in respiratory distress and needed intubation. Investigations revealed elevated liver enzymes, leukopenia, spherocytosis and lower lobe predominant consolidations and diffuse nodules in the high-resolution computed tomography. He was suspected to have cytomegalovirus (CMV) pneumonia with the above results, and further investigations revealed an extremely elevated CMV viral load. He was treated with ganciclovir followed by valganciclovir for a total of 42 days resulting in a complete recovery. Liver functions resolved with anti-viral treatment, and he was started on full anti-tuberculosis (TB) treatment. Further investigations did not reveal evidence of immunosuppression. Association of CMV and TB is explained genetically, although clinical association is rarely described. The presence of either infection should lead to higher degree of suspicion of the respective other condition in relevant clinical setting.
RESUMEN
BACKGROUND: There is currently no clinically validated biomarker to predict respiratory compromise in sudden acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Cycle threshold time (Ct), absolute lymphocyte count (AL) and neutrophil:lymphocyte ratio (NLR) have been previously evaluated for this purpose. We hypothesized that the combination of these parameters at presentation may be predictive of hypoxia (oxygen saturation <92%). METHODS: Data were collected on 118 patients with SARS-CoV-2 infection between May 2020 and April 2021. Demographics, clinical parameters and laboratory and radiological investigation results were recorded. Respiratory compromise (RC) was defined based on symptoms and signs, hypoxia and chest X-ray abnormalities. RESULTS: RC occurred in 61 (51.7%) of patients. The Ct, AL and NLR at median day 3 of illness were significantly different between patients with and without RC (Ct, RC vs not: 19.46±2.64 vs 22.62±3.37, p=0.0001; AL, RC vs not: 531.49±289.09 vs 764.69±481.79, p=0.0001; NLR, RC vs not: 3.42±0.75 vs 2.59±0.55, p=0.0001). Receiver operating characteristics analysis showed that a Ct <19.9, AL <630.8×103/µL and NLR >3.12 at median day 3 of symptoms was predictive of hypoxia on day 7 of illness (area under the curve 0.805, sensitivity 96.7%, specificity 69.1%). The predictive value for the parameters combined was significantly superior to their individual predictive power. CONCLUSIONS: Ct, AL and NLR used in combination on day 3 of symptoms are predictive of hypoxia on day 7 of SARS-CoV-2 illness.

BACKGROUND: Coronavirus disease 2019 (COVID-19) may cause clinical manifestations that last for weeks or months after hospital discharge. The manifestations are heterogeneous and vary in their frequency. Their multisystem nature requires a holistic approach to management. There are sparse data from the South Asian region on the outcomes of hospital-discharged COVID-19 patients. We assessed the posthospital discharge outcomes of a cohort of Sri Lankan COVID-19 patients and explored the factors that influenced these outcomes. METHODS: Data were prospectively collected from patients who were discharged following an admission to the Nawaloka Hospital, Sri Lanka with COVID-19 from March to June 2021. At discharge, their demographic, clinical and laboratory findings were recorded. The patients were categorised as having mild, moderate and severe COVID-19, based on the Sri Lanka Ministry of Health COVID-19 guidelines. Following discharge, information on health status, complications and outcomes was collected through clinic visits and preplanned telephone interviews. A validated (in Sri Lanka) version of the Short Form 36 health survey questionnaire (SF-36) was used to assess multi-item dimensions health status of the patients at 1, 2 and 3 mo postdischarge. RESULTS: We collected data on 203 patients (male, n=111 [54.7%]). The level of vaccination was significantly associated with disease severity (p<0.001). Early recovery was seen in the mild group compared with the moderate and severe groups. At 3 mo, on average 98% of mild and 90% of moderate/severe patients had recovered. Based on the SF-36, physical functioning dimensions, role limitation due to physical and emotional health, energy/ fatigue, emotional well-being, social functioning, pain and general health were significantly different in the moderate/severe vs mild COVID-19 groups at 1, 2 and 3 mo postdischarge (p<0.05). Twenty-three patients developed complications, of which the most common were myocardial infarction with heart failure (n=6/23; 26.1%), cerebrovascular accident (n=6/23; 26.1%) and respiratory tract infections (n=3/23; 13.01%) and there were six deaths. CONCLUSIONS: In our cohort, receiving two doses of the COVID-19 vaccine was associated with reduced disease severity. Those with mild disease recovered faster than those with moderate/severe disease. At 3 mo posthospital discharge, >90% had recovered.

A 39-year-old man with diabetes mellitus and hypertension presented two years following renal transplantation with evening pyrexia, night sweats and loss of weight. He was diagnosed with disseminated tuberculosis and invasive aspergillosis and commenced on antituberculous and antifungal therapy. Immunosuppressants except for the maintenance dose of steroids were discontinued. Two weeks later, he acquired severe COVID-19 pneumonia complicated with type 1 respiratory failure and haemodynamic instability. He was treated with non-invasive ventilation and inotropic support with a vasopressor-augmenting dose of steroids. Management challenges were diagnosing the respiratory pathologies with limited investigations, deciding on continuation of steroids in an organ transplant recipient with disseminated infection and deciding the ceiling of care in a low-resource setting given the background of multiple pulmonary insults. A multidisciplinary team decided to continue high-dose steroids and escalate to a full ceiling of care. He recovered from COVID-19 pneumonia 15 days following diagnosis and was discharged home. The potential adverse effects of steroids on tuberculosis and aspergillosis are to be monitored during follow-up.

End TB strategy by the WHO suggest active screening of high-risk populations for tuberculosis (TB) to improve case detection. Present study generates evidence for the effectiveness of screening patients with diabetes mellitus (DM) for Pulmonary TB (PTB). A study was conducted among 4548 systematically recruited patients over 45 years attending DM clinic at the National Hospital of Sri Lanka. The study units followed an algorithm specifying TB symptom and risk factor screening for all, followed by investigations and clinical assessments for those indicated. Bacteriologically confirmed or clinically diagnosed PTB were presented as proportions with 95% CI. Mean (SD) age was 62·5 (29·1) years. Among patients who completed all indicated steps of algorithm, 3500 (76·9%) were investigated and 127 (2·8%) underwent clinical assessment. Proportion of bacteriologically confirmed PTB patients was 0·1% (n = 6,95%CI = 0·0-0·3%). None were detected clinically. Analysis revealed PTB detection rates among males aged ≥60 years with HbA1c ≥ 8 to be 0·4% (n = 2, 95%CI = 0·0-1·4%). The study concludes that active screening for PTB among all DM patients at clinic settings in Sri Lanka, to be non-effective measure to enhance TB case finding. However, the sub-category of diabetic males with uncontrolled diabetics who are over 60 years of age is recommended as an option to consider for active screening for PTB.

INTRODUCTION: International guidelines recommend pulmonary rehabilitation (PR) should be offered to adults living with chronic obstructive pulmonary disease (COPD), but PR availability is limited in Sri Lanka. Culturally appropriate PR needs to be designed and implemented in Sri Lanka. The study aims to adapt PR to the Sri Lankan context and determine the feasibility of conducting a future trial of the adapted PR in Sri Lanka. METHODS AND ANALYSIS: Eligible participants will be identified and will be invited to take part in the randomised controlled feasibility trial, which will be conducted in Central Chest Clinic, Colombo, Sri Lanka. A total of 50 participants will be recruited (anticipated from April 2021) to the trial and randomised (1:1) into one of two groups; control group receiving usual care or the intervention group receiving adapted PR. The trial intervention is a Sri Lankan-specific PR programme, which will consist of 12 sessions of exercise and health education, delivered over 6 weeks. Focus groups with adults living with COPD, caregivers and nurses and in-depth interviews with doctors and physiotherapist will be conducted to inform the Sri Lankan specific PR adaptations. After completion of PR, routine measures in both groups will be assessed by a blinded assessor. The primary outcome measure is feasibility, including assessing eligibility, uptake and completion. Qualitative evaluation of the trial using focus groups with participants and in-depth interviews with PR deliverers will be conducted to further determine feasibility and acceptability of PR, as well as the ability to run a larger future trial. ETHICS AND DISSEMINATION: Ethical approval was obtained from the ethics review committee of Faculty of Medical Sciences, University of Sri Jayewardenepura, Sri Lanka and University of Leicester, UK. The results of the trial will be disseminated through patient and public involvement events, local and international conference proceedings, and peer-reviewed journals. TRIAL REGISTRATION NUMBER: ISRCTN13367735.

Measurement of an individuals ability to respond to polysaccharide antigens is a crucial test to determine adaptive immunity. Currently the response to Pneumovax® is utilized but with the success of Prevnar®, measurement of the response to Pneumovax may be challenging. The aim of the study was to assess the response to Typhi Vi vaccination in both children and adult control groups and patients with primary immunodeficiency (PID). In the control groups, >95% of the individuals had pre Typhi Vi vaccination concentrations <100 U/mL and there was significant increase in concentration post Typhi Vi vaccination (p<0.0001) with>94% achieving ≥3 fold increase in concentration (FI). The response to Typhi Vi vaccination was significantly lower in both children (p = 0.006) and adult (p = 0.002) PID groups when compared to their control groups. 11% and 55% of the children and adult PID groups respectively did not obtain a response >3FI. There were no significant differences between the responses obtained in the children and adult PID groups. When all individuals with PID were separated into those with either hypogammaglobulinemia (HYPO) or common variable immunodeficiency (CVID), both groups had a significantly lower median FI than the control group (19, 95%CI 5-56 vs 59, 95%CI 7-237; p = 0.01 and 1, 95%CI 1-56 vs 32, 95%CI 5-136; p = 0.005). Further, a >3FI differentiated the antibody responses between both the CVID and HYPO groups and their control groups (AUC: 0.83, 95%CI: 0.65-1.00, p = 0.005 and 0.81, 95% CI: 0.65-0.97, p = 0.01). The data suggests that measurement of the response to Typhi Vi vaccination could represent a complementary assay for the assessment of the response to a polysaccharide vaccine.
