Neurogenic Supine Hypertension and Cardiovascular Autonomic Dysfunction in Patients with Parkinson's Disease.

Background: Natural history and disease progression in patients with Idiopathic Parkinson's Disease (PD) is quite heterogeneous. Autonomic dysfunction occurs commonly among Idiopathic PD patients. Heart rate variability and ambulatory blood pressure monitoring are used to assess cardiac autonomic dysfunction. The prevalence and magnitude of supine hypertension in Indian PD patients has not been studied to date. The present study aimed to record cardiovascular autonomic functions and supine hypertension in PD patients and to correlate them with the age of onset, duration and severity of the disease, and non-motor symptom burden. Material and Methods: The cross-sectional study involved 60 PD patients. Webster rating scale was used to determine the disease severity. Non-motor symptom burden was assessed using the Non-Motor Symptom Scale (NMSS). Ambulatory blood pressure monitoring and heart rate variability parameters determined cardiac autonomic function. Supine hypertension was defined as Systolic Blood Pressure (SBP) ≥150 mmHg and/or DBP ≥90 mmHg. Less than 10% decrease or even increase in blood pressure during the night were classified as non-dippers. Pearson coefficient was used appropriately to establish correlation. P ≤ 0.05 was considered significant. Results: Age of onset was 61.2 ± 8.7 years and duration of disease was 1.7 ± 1.1 years. Mean Webster and non-motor symptom scores were 12.7 ± 4.4 and 15.5 ± 8.0, respectively. About 50 patients (83%) were non-dipper, while 32 (53%) had supine hypertension. Low Frequency oscillations (LF) (r = 0.28), High Frequency oscillations (HF) (r = 0.29), Standard Deviation NN intervals (SDNN) (0.26), and Root Mean Squared Successive Differences of NN intervals (RMSSD) (r = 0.28) correlated significantly with non-motor symptoms scale. LF (r = -0.39), HF (r = -0.43), SDNN (-0.40), RMSSD (r = -0.41), NN50 (r = -0.38), PNN50 (r = -0.42), mean SBP (r = 0.26), and mean DBP (r = 0.33) correlated significantly with disease duration. PNN50 (r = -0.255), mean SBP (r = -0.29), and mean DBP (r = -0.27) correlated significantly with age at onset. Conclusion: Awareness regarding neurogenic supine hypertension is needed as it occurs commonly among Indian PD patients. Heart rate variability (HRV) parameters and ambulatory blood pressure are of significant help in the detection of early cardiovascular autonomic dysfunction and correlate significantly with disease duration and non-motor symptom burden among PD patients.

Transient Elastography of Liver and Serum Hyaluronic Acid Levels In Adult Transfusion Dependent Thalassemia Patients.

Iron overload occurs as a result of multiple blood transfusions and increased iron absorption in thalassemia patients. Iron deposition in liver results in liver stiffness and fibrosis. Non invasive methods including imaging and serum biomarkers have been introduced for assessment of liver fibrosis. We aimed to study liver stiffness using transient elastography and serum hyaluronic acid levels and correlate them with serum ferritin levels in adult transfusion dependent beta thalassemia patients. MATERIAL: 70 transfusion dependent thalassemia patients of age ≥18 years, registered at Thalassemia Day Care Centre were subjected to investigations like CBC, Liver function tests, viral markers, serum ferritin, serum hyaluronic acid levels and transient elastography. Fibrosis indices like FIB-4, AAR and APRI were also calculated. 45 patients had T2*MRI reports with them; which were also included and analysed. Spearman coefficient r was used to test correlations between TE values and serum HA levels with other variables. OBSERVATION: 70 patients (41 male and 29 female) with mean age of 24.09±5.38 years and BMI 20.51 ±3.47 kg/m², were enrolled. Median values of hemoglobin, AST, ALT, TE, serum HA and serum ferritin were, 9.15 g/dl, 42 IU/L, 47.50 IU/L, 9.1 kPa, 284 ng/dl and 1841 ng/ml, respectively . TE values had significant positive correlation with serum ferritin (r=0.5, p < 0.001), ALT (r=0.59, p < 0.001), AST (r=0.58, p< 0.001), APRI (r=0.5, p<0.001) and FIB-4 (p=0.02), respectively and significant negative correlation with T2* MRI (ms) (r= -0.5, p<0.001). No significant correlation of HA was found with any variable. CONCLUSION: Transient elastography can be used as a non expensive, easily accessible and non invasive marker of liver iron overload. Further detailed studies are required to establish the role of serum Hyaluronic acid in thalassemia patients.

Pancreatic tuberculosis: An unusual presentation.

Tuberculosis (TB) of pancreas is a rare presentation in both immune-competent and immune-suppressed patients. Its presenting clinical features are usually vague and non-specific, while radiological features mimic other common pancreatic conditions such as malignancy, so it is often misdiagnosed. It commonly involves the head and the uncinate process of the pancreas. We report a middle-aged immune-compromised man who presented with left-sided tubercular pleural effusion and later was diagnosed as pancreatitis by clinical presentation and TB of pancreas on computed tomography of the abdomen.

Post-COVID Interstitial Lung Disease - The Looming Epidemic.

INTRODUCTION: As India recovers from the two waves of the Covid-19 pandemic, its sequelae are posing a new challenge to the physician. These may vary from fatigue and myalgia to persistent, and even worsening breathlessness, due to pulmonary fibrosis. Management of post-COVID-19 pulmonary fibrosis is currently limited to symptomatic management and largely an unexplored aspect. OBJECTIVES: To draw attention to the imminent threat of post-COVID-19 interstitial lung disease (PC-ILD) in COVID survivors through a case series. METHODS: A retrospective analysis of data was done in patients admitted with severe COVID in December 2020 at our tertiary care hospital, and who had a prolonged stay with symptoms and signs suggestive of pulmonary fibrosis. HRCT was done to make a diagnosis of pulmonary fibrosis or ILD. Three such patients were identified. RESULTS: All the three cases were laboratory proven SARS CoV-2 positive cases and had developed pulmonary fibrosis, with traction bronchiectasis, termed here as PC-ILD (Post Covid-Interstitial Lung Disease). Two of them survived and had improved oxygen saturation on room air at three-month follow-up, while one patient had developed arrhythmia and died. CONCLUSION: PC- ILD is one of the emerging complications of COVID-19 pneumonia. A proactive follow-up programme should be undertaken to identify and manage this looming epidemic.

Pancreatic Injury in COVID-19 Patients.

BACKGROUND AND AIM: Coronavirus disease 2019 (COVID 2019) outbreak caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may cause multisystem dysfunction. We studied pancreatic injury (serum amylase and serum lipase levels) in COVID-19 patients. METHODS: A retrospective study involving 42 COVID-19 patients (diagnosed by real-time PCR) admitted to a tertiary care hospital was conducted. Serum amylase and serum lipase levels were analysed in relation to severity of COVID-19 and mortality. RESULTS: Mean age of patients was 50 ± 16 years, with male to female ratio of 3.7:1. Serum amylase was elevated in 14 patients (33%). Serum lipase was elevated in 7 out of 29 patients (24.1%). Mortality was seen in 18 patients (42.8%). Serum amylase or lipase did not correlate with severity of COVID-19 or its mortality. However, both patients who had high lipase (>3times) died. CONCLUSION: The prevalence of hyperamylasemia in patients of COVID-19 was 33%, while that of elevated lipase was 24.1%. Pancreatic injury failed to show any statistically significant relation to severity or outcome of COVID-19.

COVID-19 and Tuberculosis: A Meeting of Two Pandemics!

Coronavirus disease 2019 (COVID-19), causes serious respiratory illness manifesting as pneumonia, adult respiratory distress syndrome and respiratory failure. Amidst the rising number of cases and deaths, it is imperative to not forget Tuberculosis (TB) which is another pandemic existing since centuries. There could be dire consequences for tuberculosis patients globally especially in low and middle income countries with a high burden of disease and overwhelmed health care systems. Tuberculosis is still the leading infectious killer worldwide, and therefore, it is crucial to reflect on the interaction between the two diseases. Evidence suggests that both COVID-19 and tuberculosis have a synergistic relationship, boosting detrimental effect of each other, disrupting existing health care models, and also worsening the clinical outcomes in terms of morbidity and mortality. This review aims to draw attention towards this pertinent clinical issue, and tries to unravel the intricate relationship between COVID-19 and tuberculosis, as also the role of BCG vaccination to combat the COVID-19 pandemic.

Study of Clinical Profile of Patients of Non Alcoholic Fatty Liver Disease and its Association with Metabolic Syndrome.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is considered to be the commonest liver problem in the western world and is increasingly being recognised as a major cause of liver-related morbidity and mortality. It is known to be associated with various metabolic abnormalities, but not much information regarding association between the metabolic disease and the severity of fatty liver is available. AIMS: To study the clinical profile of patients of NAFLD with varying degrees of severity as diagnosed by ultrasonography and to study the correlation between the non-alcoholic fatty liver disease and metabolic syndrome along with its individual components. MATERIAL AND METHODS: The study was an observational and analytical study of patients diagnosed as NAFLD, attending OPD and indoor patients of the Department of Medicine, J A Group of hospitals. All patients diagnosed as NAFLD were investigated for metabolic syndrome according to the NCEP ATP 3 Criteria and a relationship between NAFLD and metabolic syndrome was studied. RESULTS: 51.4% of patients of NAFLD had metabolic syndrome and statistical significance was found in AST, diabetes mellitus and lipid profile. CONCLUSIONS: There is higher prevalence of all the components of metabolic syndrome in cases of NAFLD. Its early detection will help in modifying the disease course, delaying complications and will also play a major role in preventive cardiology.
