Severity and Mortality Predictors of COVID-19 Patients with Thrombotic Events-Evidence from the "COVID-One" Hospital in Albania.

COVID-19 vaccination leads to lower infection, morbidity, and mortality rates. However, COVID-19 infection leads to the development of coagulopathy-related manifestations in the form of both venous and arterial thromboembolism. This study aimed to assess the severity and mortality predictors of COVID-19 patients with thrombotic events in hospitalized patients in Albania. This is a retrospective study conducted in the "Mother Tereza" University Hospital of Tirana. Data were retrieved from the electronic databases of the hospital and only COVID-19 cases admitted to the infectious department during August-December 2020 were selected. Patients who, at admission, had a C-reactive protein (CRP) (mg/L) more than double and a D-dimer (ng/mL) more than triple according to international standards were included in the study. We performed univariate and multivariable logistic regression analysis, calculating unadjusted and adjusted odds ratios (ORs). A p-value < 0.05 was considered statistically significant. The study population included 60 hospitalized persons with a mean age of 64.4 years. Increased lactate dehydrogenase (LDH) (OR = 2.93; 95% CI = 0.82-10.42, p-value = 0.1) and increased creatine kinase (CK) (OR = 2.17; 95% CI = 0.63-7.46, p-value = 0.22) were related with increased probability of death. Moreover, a decreased number of lymphocytes was associated with increased mortality but with no statistical significance (OR = 0.40; 95% CI = 0.11-1.40, p-value = 0.15). The survival rate was higher for patients without comorbidities (p = 0.045). These results could serve as a baseline and as a reference for healthcare personnel who provides services to hospitalized patients with COVID-19. Further studies should take into consideration the vaccination of the population as well as including more hospitals and patients.

Atypical Haemolytic Uremic Syndrome Associated with COVID-19: Case Report

BACKGROUND AND AIMS Renal manifestations are common in hospitalized patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We report here the case of a patient with confirmed SARS-CoV-2 infection with the clinical picture of atypical haemolytic uremic syndrome (aHUS). METHOD Case report RESULTS Our case is a 31-year-old man with a nasopharyngeal swab with real-time reverse-transcriptase polymerase chain reaction (RT-PCR) for SARS-CoV-2 positive, who was hospitalized in the Clinic of Infectious Diseases. His medical history had a respiratory illness of 7-day evolution characterized by cough, fever, dyspnoea, muscle pain, nausea, vomiting and non-bloody diarrhoea, and decreased urine output with dark colour urine. The chest computed tomography (CT) scan showed few rounded ground-glass opacities. Laboratory tests at admission revealed the following: (i) acute kidney injury stage 3 with a serum creatinine of 3.85 mg/dL (basal value 0.9 mg/dL);serum urea 221 mg/dL. His urinary volume in the first 24 h of hospitalization was 800 mL. (ii) Severe haemolytic anaemia with haemoglobin (Hgb) level of 3.7 g/dL, and peripheral smear showing large number of schistocytes, haptoglobin <10 mg/dL and indirect bilirubin 9.7 mg/dL, direct coombs testing was negative;reticulocyte count 8.9%. (iii) Severe thrombocytopaenia with platelet count of 25 000/µL, prothrombin time 45%, international normalized ratio 1.7, D-dimer 1082 ng/dL and fibrinogen 880 mg/dL. Increased blood levels of enzymes and inflammatory markers were present: lactate dehydrogenase 1867 U/L and protein C reactive 9.1 mg/dL. Electrolyte disturbances characterized by hyperkalaemia, hyperphosphatemia, hypocalcaemia and severe metabolic acidosis. Dynamic changes of laboratory data are presented in Table 1.Table 1.

The usual liver panel tests, alkaline phosphatase, γ-glutamyl transferase and albuminemia were normal. Toxic hepatitis was excluded. Hepatobiliary and spleen imaging (ultrasonography) was normal. ELISA serologic tests for HIV, hepatitis B, hepatitis C virus and cytomegalovirus were negative. Serological and virological tests for hepatitis A, B, C, HIV and CMV were negative. Stool was negative for Shiga toxin-producing Escherichia coli (STEC). The results of antinuclear antibodies and anti-smooth-muscle antibodies were negative, C3 serum level was mildly depressed (82 mg/dL;normal range 88–201 mg/dL) and C4 serum level was normal (20 mg/dL;normal range 10–44 mg/dL). ADAMTS13 activity was 90% on day 10. He was treated with broad spectrum antibiotics, intravenous dexamethasone and supportive therapy. One week from admission, renal function recovered, and 1 week after intravascular haemolysis and thrombocytopaenia recovered. The patient was hospitalized for 21 days. CONCLUSION Close monitoring and early intervention can help for a better outcome of SARS-CoV-2 patients complicated with aHUS.

Important early prognostic laboratory indicators for COVID-19 mortality

Background COVID-19 has been marked as a highly pathogenic coronavirus of COVID-19 disease which has caused a pandemic into the human population, with a different course in different people, which contributed to the death of approximately over 5.02 million confirmed cases worldwide up till now. For this reason, it is quite important to have the earliest possible evaluation of laboratory-assisted indicators, especially for mortality risk prediction in developing countries, in addition to other clinical and imaging evaluations in order every physician to make the right medical decision. Methods In total, 277 patients of Infectious Diseases Hospital, UHC “Mother Teresa” were enrolled. All of them tested positive for COVID-19. We evaluated indicators such as d-dimer (N = 0–500 μg/L), lactate dehydrogenase LDH (N = 95–200 U/L) and the neutrophil/lymphocyte ratio (control group = 1.7 ± 0.392) in two groups of patients, the first one of 144 patients who were discharged from the hospital and the second one of 133 patients who died. Results What we observed was that the results were different for every test we performed in each group. Neutrophil/lymphocyte ratio was 8.69 ± 4.9 for the first group versus 14.7 ± 12.3 for the second one, P<0.05 (P = 0.013), LDH = 427 ± 241 versus 715 ± 347, P<0.05 (P = 0.0002), d-dimer = 1387 ± 763 versus 2650 ± 1322, P>0.05 (P = 0.28). Conclusions In addition to LDH as a prognostic factor, the neutrophil/lymphocyte ratio was considered as a low cost examination for severe prognosis and mortality risk (P<0.05), which can also serve as an alert for primary services for patient hospitalization, especially in developing countries after his clinical and image evaluation.

Risk factors for poor outcome of patients with Coronavirus disease 2019 (COVID-19) in Albania.

INTRODUCTION: The study aims to identify potential risk factors for the poor outcome of hospitalized patients with SARS-CoV-2 infection in Albania. METHODOLOGY: A retrospective observational study on 133 consecutive hospitalized patients at "COVID 1" Hospital, University Hospital Center of Tirana. The study analyzed the correlation between potential risk factors and in-hospital mortality. RESULTS: The study included 133 patients, 65.4% of the patients were male, age 60.46 ± 13.53 years. The mortality rate resulted in 22.6%. Univariate analysis revealed that early risk factors for mortality included: laboratory alterations on admission, such as lymphocytes count < 1.000/mm3 (OR = 3.30, 95% CI = 1.17-9.33), lactate dehydrogenase > 250 U/L (OR = 12.48, 95% CI = 1.62-95.78) and D dimer > 2 mg/L (OR = 4.72, 95% CI = 1.96-11.36); lung parenchymal involvement > 75% on chest computed tomography on admission (OR = 54.00, 95% CI = 11.89 - 245.11). Cox proportional hazard regression showed that independent risk factors for mortality were lung parenchymal involvement > 75% on chest computed tomography (HR = 8.31, 95%CI: 1.62-42.45) and occurrence of complications during hospital stay (OR = 10.28, 95% CI = 2.02-52.33). CONCLUSIONS: The risk of poor outcome can be predicted from the early stage of COVID 19 disease, using laboratory data and chest computed tomography. Among patients with COVID 19, lung parenchymal involvement and alterations > 75% on chest computed tomography on admission and laboratory findings, such as lymphocytopenia, and elevated lactate dehydrogenase and D dimer levels, turned out to be early risk factors for in-hospital mortality.

Severe hypocalcaemia in a COVID-19 female patient.

SUMMARY: Comorbidities are a risk factor for patients with COVID-19 and the mechanisms of disease remain unclear. The aim of this paper is to present a case report of an COVID-19 patient with severe hypocalcaemia. This is a report of an 81-year-old female, suffered from myalgia and fatigue for more than 3-4 weeks. Fever and cough appear 2 days before she presented to the emergency room. On physical examination, she was febrile with a temperature of 38.8°C, accompanied by cough, sore throat, headache, fatigue, and muscle ache. Her past medical history was remarkable with no chronic disease. She had lymphopenia. Laboratory test revealed moderate liver dysfunction, hypoalbuminemia, and severe hypocalcaemia (serum corrected calcium level: 5.7 mg/dL). Parathyroid hormone (PTH) was 107.9 pg/mL (range: 15-65) and 25(OH)2D levels was 4.5 ng/mL (range: 25-80). Chest CT scan detected peripheral ground-glass opacity. Throat swab for coronavirus by RT-PCR assay tested positive for the virus. She was treated with lopinavir/ritonavir, third generation cephalosporin, anticoagulant, daily high-dose calcium acetate, vitamin D3, fresh frozen plasma and oxygen therapy. She was discharged after two negative throat swab tests for coronavirus by conventional RT-PCR. LEARNING POINTS: Comorbidities are a risk factor for patients with COVID-19. Laboratory findings are unspecific in COVID-19 patients; laboratory abnormalities include lymphopenia, elevated of LDH, CPK and the inflammatory markers, such as C reactive protein, ferritinemia and the erythrocyte sedimentation rate. In addition to inflammatory markers, in COVID-19 patients it is crucial to check the level of vitamin D and calcium. There may be a correlation between vitamin D deficiency and the severity of COVID-19 disease.

Repurposed Antiviral Drugs for Covid-19 - Interim WHO Solidarity Trial Results.

BACKGROUND: World Health Organization expert groups recommended mortality trials of four repurposed antiviral drugs - remdesivir, hydroxychloroquine, lopinavir, and interferon beta-1a - in patients hospitalized with coronavirus disease 2019 (Covid-19). METHODS: We randomly assigned inpatients with Covid-19 equally between one of the trial drug regimens that was locally available and open control (up to five options, four active and the local standard of care). The intention-to-treat primary analyses examined in-hospital mortality in the four pairwise comparisons of each trial drug and its control (drug available but patient assigned to the same care without that drug). Rate ratios for death were calculated with stratification according to age and status regarding mechanical ventilation at trial entry. RESULTS: At 405 hospitals in 30 countries, 11,330 adults underwent randomization; 2750 were assigned to receive remdesivir, 954 to hydroxychloroquine, 1411 to lopinavir (without interferon), 2063 to interferon (including 651 to interferon plus lopinavir), and 4088 to no trial drug. Adherence was 94 to 96% midway through treatment, with 2 to 6% crossover. In total, 1253 deaths were reported (median day of death, day 8; interquartile range, 4 to 14). The Kaplan-Meier 28-day mortality was 11.8% (39.0% if the patient was already receiving ventilation at randomization and 9.5% otherwise). Death occurred in 301 of 2743 patients receiving remdesivir and in 303 of 2708 receiving its control (rate ratio, 0.95; 95% confidence interval [CI], 0.81 to 1.11; P = 0.50), in 104 of 947 patients receiving hydroxychloroquine and in 84 of 906 receiving its control (rate ratio, 1.19; 95% CI, 0.89 to 1.59; P = 0.23), in 148 of 1399 patients receiving lopinavir and in 146 of 1372 receiving its control (rate ratio, 1.00; 95% CI, 0.79 to 1.25; P = 0.97), and in 243 of 2050 patients receiving interferon and in 216 of 2050 receiving its control (rate ratio, 1.16; 95% CI, 0.96 to 1.39; P = 0.11). No drug definitely reduced mortality, overall or in any subgroup, or reduced initiation of ventilation or hospitalization duration. CONCLUSIONS: These remdesivir, hydroxychloroquine, lopinavir, and interferon regimens had little or no effect on hospitalized patients with Covid-19, as indicated by overall mortality, initiation of ventilation, and duration of hospital stay.
