    A Case of Acute Encephalitis in COVID-19 Patient: A Rare Complication

    by Shah T. Sarmast, Alaa S. Mohamed, Zain Amar, Sobia Sarwar, Zahoor Ahmed

    Coronavirus disease 19 (COVID-19) is a respiratory disease, has a variable presentation, and neurological involvement in COVID-19 is not widely reported. We report a rare case of acute encephalitis in a COVID-19 patient presented with fever, dry cough, and dyspnea. She had a fever, tachypnea, and tachycardia. On auscultation, she had scattered wheezing in both lung fiends. Chest X-ray revealed small infiltrates in the lower lobe of both lungs. A nasopharyngeal swab for the COVID-19 polymerase chain reaction was positive. Later on, she developed sudden onset confusion accompanied by restlessness and visual hallucinations. Neurological examination revealed an altered level of consciousness, slight trembling of the limbs, psychomotor restlessness, and poor speech with no signs of meningeal irritation. Magnetic resonance imaging of the brain revealed diffuse hyperintense signals. A possible diagnosis of acute encephalitis was made due to concurrent COVID-19 infection and lack of other findings suggesting a diagnosis other than COVID-19. She was treated with azithromycin, tocilizumab, and methylprednisolone. Her condition started improving gradually.

    Introduction Atherosclerosis is considered a major cause of coronary artery disease (CAD). Pathogenesis of atherosclerosis involves the oxidation of low-density lipoprotein (LDL) within the lysosomes of macrophages. Ferritin and iron have pro-oxidant properties, and ferritin is an independent positive determinant of oxidized LDL level. In this study, we will determine the association between ferritin and serum iron levels and CAD. Methods This case-control study was conducted in the cardiology unit of a tertiary care hospital in Pakistan from December 2020 to April 2021. After taking informed consent, 400 patients with a confirmed diagnosis of CAD were enrolled. Another set of 400 patients without a history of CAD were included in the control group. A blood sample of 5 ml was drawn and sent to the laboratory to test for ferritin, serum iron, and total iron-binding capacity (TIBC). Ferritin, serum iron, and iron-binding capacity were compared between the case and control groups. Results Serum ferritin was significantly higher in patients with CAD compared to patients without CAD (921.21 +/- 201.21 ug/L vs. 101.21 +/- 92.21 ug/L; p-value: <0.0001). Serum TIBC was significantly lower in patients with CAD compared to patients without CAD (302.12 +/- 101.75 umol/L vs. 362.12 +/- 82.16 umol/L). Conclusion Patients with raised levels of ferritin should consult a physician to manage their ferritin levels since they are at a greater risk of CAD. Treatment ranges from lifestyle changes to pharmacological therapy, thus reducing the overall risk and normalizing the ferritin levels.

    Association Between Diabetic Retinopathy and Carotid Intima-Media Thickness

    by Abdul Subhan Talpur, Zain Amar, Shumaila Zafar, Asadullah Memon, Abdul Habib Eimal Latif, Farukhzad Hafizyar, Sara Hashim, Kefayatullah Nazary

    Patients with diabetes having advanced stage of diabetic retinopathy (DR) may predict future risk of coronary artery disease. To predict cardiovascular outcomes carotid intima-media thickness (CIMT) is utilized in diabetic patients. The aim of our study was the evaluation of the relationship between retinopathy and CIMT as two valuable non-invasive methods for early detection of micro- and macrovascular complication of diabetes. This comparative cross-sectional study was conducted in the internal medicine ward of tertiary care hospital in Pakistan from November 2020 to January 2021. Three hundred patients with type 2 diabetes mellitus and 300 control subjects were enrolled in the study after taking informed consent. Ophthalmological examination was done to screen patients for DR. CIMT was evaluated by a Doppler ultrasound for both carotid arteries. Carotid artery intimal thickness was more in patients with retinopathy compared to patients without retinopathy in both right (0.77 ± 0.16 vs. 0.66 ± 0.12; p-value: <0.0001) and left carotid artery (0.77 ± 0.15 vs. 0.65 ± 0.11; p-value: <0.0001). In our study, there was a correlation between DR and CIMT. Screening for DR, which may be a potential early marker for complications, may help detect patients at risk of various macro and microvascular complications.

    Role of Cod Liver Oil in Reducing Elevated Lipid Parameters

    by Faryal Fatima, Asadullah Memon, Shumaila Zafar, Zain Amar, Abdul Subhan Talpur, Sara Hashim, Hamza Maqsood, Farukhzad Hafizyar, Besham Kumar

    The health benefits of cod oil, which includes omega-3 fatty acids, have been of considerable interest to medicine due to its promising results. Studies have shown successful therapeutic effects of a high dietary intake of omega-3 fatty acids by reducing the synthesis of very-low-density lipoprotein, with subsequent low levels of serum triglycerides. This single-blind placebo-controlled two-arm interventional study was conducted in the internal medicine unit of a tertiary care hospital from October 2020 to April 2021. 600 treatment naïve patients with elevated cholesterol levels and/or elevated low-density lipoprotein (LDL) were enrolled in the study and randomized into two groups. The study group received 415 mg cod liver oil daily as a capsule in a bottle, in addition to 10 mg rosuvastatin. On the other hand, the control group received 10 mg rosuvastatin with placebo capsules in an identical bottle. Participants were followed up on day 30. There was relatively more significant reductions in the total cholesterol (152.22 ± 29.75 mg/dL vs. 171.65 ± 31.21 mg/dL; p-value: <0.0001) and LDL (72.41 ± 27.52 mg/dL vs. 79.15 ± 29.12 mg/dL; p-value: <0.0001) in the intervention group compared to the placebo group after day 30. There was a significant reduction in all lipid values in both groups at day 30 as compared to day 0. Our study indicates that cod liver oil in addition to rosuvastatin reduces cholesterol more compared to rosuvastatin alone. However, in all cases, lifestyle changes should be the first modification adopted by the patients. Further large-scale trials are needed to examine the role of cod liver oil in reducing lipid values.
