RESUMEN
BACKGROUND: Considering the dearth of research on the complications of Sinopharm coronavirus disease 2019 (COVID-19) vaccine in the immunocompromised individuals and the lack of available data on COVID-19 vaccination from Iran. OBJECTIVE: This study aimed to investigate the efficacy of vaccine of Sinopharm COVID-19 vaccine and its complications in bone marrow transplant (BMT) recipients. METHODS: This was a retrospective cross-sectional study was conducted on 250 patients with BMT who were referred to Montaserieh Hospital, Mashhad, Iran. Among them 53 case who received at least two doses of Sinopharm COVID-19 vaccine from March to January 2021 were entered in this study. The data were extracted from a student dissertation (Code:4000370). RESULTS: Sinopharm vaccine side effects were reported only in 7.7% of the patients, and Shingles was the only serious side effect of the Sinopharm vaccine, which was observed only in one case. The results also revealed that Sinopharm COVID-19 vaccine side effects were not related to age or gender. Infection with Delta variant of COVID-19 was reported in 7.5% (n=4) and no mortality was reported among them. Vaccine failure was reported in 39.6% of the cases; however, no mortality was reported among patients infected with the Omicron variant of COVID-19. CONCLUSION: In summary, it seems that Sinopharm COVID-19 vaccine adverse effects were not serious among stem cell transplant recipients. However, it may lead to some severe complications in the population. Vaccine failure against the Delta and Omicron variants of COVID-19 has been reported among more than one-third of BMT patients; however, no mortality was observed among BMT patients infected with the new variants of COVID-19.
RESUMEN
BACKGROUND: There are various vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, vaccination may lead to some complications. OBJECTIVE: This study aimed to investigate the complications of transplant recipients who received Sinopharm COVID-19 vaccine. METHODS: This was a retrospective cross-sectional study conducted among 667 transplant recipients (211 liver transplant recipients and 456 kidney transplant recipients), who received the Sinopharm COVID-19 vaccine during March to August 2021 and had medical records in Montaserieh Hospital, affiliated to Mashhad University of Medical Sciences, Mashhad, Iran. The demographic and clinical information as well as patient's symptoms after each dose of the vaccine were recorded. RESULTS: Only 16.8% and 13.7% of the patients experienced some symptoms following the first and second doses of Sinopharm vaccine, respectively. No significant difference was observed between patients younger than 50 years and those aged 50 years and over in terms of complication rate of Sinopharm vaccine (P>0.005). Vaccine failure was reported in 10% of the cases; however, mortality rate due to infection with the Delta variant of COVID-19 in this population was reported to be 0.7%. CONCLUSION: Based on the obtained results, adverse reactions of the Sinopharm COVID-19 vaccine are generally mild, predictable, and non-life-threatening both in the first and second doses. Vaccine failure was reported in 10% of the cases; however, mortality due to infection with the Delta variant of COVID-19 was reported in less than 1% of the cases.
RESUMEN
Background and Aims: Immunosuppressive therapy has a key role in developing coronavirus disease-2019 (COVID-19)-associated mucormycosis. In this study, we investigated the effect of the type and cumulative dose of immunosuppressive agents on COVID-19-associated mucormycosis. Methods: We designed a descriptive cross-sectional study involving three COVID-19 hospitals in Iran. Clinical and demographic data were gathered from the medical records and checked by two independent researchers to minimize errors in data collection. Results: Seventy-three patients were included in the study. The mean age of cases was 57.41 (SD = 12.64) and 43.8% were female. Among patients, 20.5% were admitted to the intensive care unit (ICU) during COVID-19. Furthermore, 17 patients (23.29%) had a history of diabetes mellitus. Sixty-nine patients (94.52%) had a history of receiving corticosteroids (dexamethasone) during treatment of COVID-19, and of those, five patients (6.85%) received Tocilizumab beside. The mean cumulative dose of corticosteroids prescribed was 185.22 mg (SD = 114.738). The average cumulative dosage of tocilizumab was 720 mg (SD = 178.89). All of the included patients received amphotericin B for mucormycosis treatment, and 42 survived (57.53%). Also, there was a significant relationship between hospitalization in ICU for COVID-19 and the mucormycosis outcome (p = 0.007). However, there weren't any significant associations between cumulative doses of immunosuppressive drugs and mucormycosis outcome (p = 0.52). Conclusion: The prevalence of COVID-19-associated mucormycosis is increasing and should be considered in the treatment protocols of COVID-19. Controlling risk factors such as diabetes, malignancy and the administration of immunosuppressive agents based on recommended dosage in validated guidelines are ways to prevent mucormycosis.
RESUMEN
Objective: To investigate the incidence of coronavirus disease 2019 (COVID-19) cases, hospitalizations and deaths in Iranians vaccinated with either AZD1222 Vaxzevria, CovIran® vaccine, SARS-CoV-2 Vaccine (Vero Cell), Inactivated (lnCoV) or Sputnik V. Methods: We enrolled individuals 18 years or older receiving their first COVID-19 vaccine dose between April 2021 and January 2022 in seven Iranian cities. Participants completed weekly follow-up surveys for 17 weeks (25 weeks for AZD1222) to report their COVID-19 status and hospitalization. We used Cox regression models to assess risk factors for contracting COVID-19, hospitalization and death. Findings: Of 89 783 participants enrolled, incidence rates per 1 000 000 person-days were: 528.2 (95% confidence interval, CI: 514.0-542.7) for contracting COVID-19; 55.8 (95% CI: 51.4-60.5) for hospitalization; and 4.1 (95% CI: 3.0-5.5) for death. Compared with SARS-CoV-2 Vaccine (Vero Cell), hazard ratios (HR) for contracting COVID-19 were: 0.70 (95% CI: 0.61-0.80) with AZD1222; 0.73 (95% CI: 0.62-0.86) with Sputnik V; and 0.73 (95% CI: 0.63-0.86) with CovIran®. For hospitalization and death, all vaccines provided similar protection 14 days after the second dose. History of COVID-19 protected against contracting COVID-19 again (HR: 0.76; 95% CI: 0.69-0.84). Diabetes and respiratory, cardiac and renal disease were associated with higher risks of contracting COVID-19 after vaccination. Conclusion: The rates of contracting COVID-19 after vaccination were relatively high. SARS-CoV-2 Vaccine (Vero Cell) provided lower protection against COVID-19 than other vaccines. People with comorbidities had higher risks of contracting COVID-19 and hospitalization and should be prioritized for preventive interventions.

RESUMEN
Background: Coronavirus disease 2019 (COVID-19) pandemic is increasingly recognized as a serious, worldwide public health concern. Most of the patients with COVID-19 are asymptomatic or show mild symptoms. It is important to identify the unusual manifestations and their long-term complication. Case presentation: A case of COVID-19 in 45 years old man with septic arthritis due to Staphylococcus aureus is presented. COVID-19 was diagnosed using real-time polymerase chain reaction without obvious clinical manifestation. The patient had no history of trauma or inflammatory arthritis and had progressive left knee pain and limitation of movement. Knee X-ray was normal. Aspiration of the knee joint fluid showed a cloudy and purulent appearance. The patient was admitted to hospital and immediately treated with vancomycin 1gr/12 hr. A polymerized chain reaction (PCR) test for COVID-19 was performed, which was positive 24 h after hospitalization. Staphylococcus aureus was reported in synovial fluid culture which was sensitive to vancomycin and ciprofloxacin, thus vancomycin was continued. On the 4th day of hospitalization the patient had cough, therefore underwent CT scan lungs and ground-glass opacities (GGO) characteristic of COVID-19 were noticed. Favipiravir and interferon were started. Patient's knee aspiration was performed for 5 consecutive days. On the 6th day of hospitalization, joint fluid markedly decreased and the patient's oxygen saturation was 96%. One week after hospitalization, the patient was discharged and a month later knee examination was completely normal. Conclusions: Septic arthritis should be considered in the manifestations or co-morbidity of COVID-19 patients with joint pain, swelling or redness.
RESUMEN
Potential therapeutic approaches in coronavirus disease 2019 (COVID-19) comprise antiviral and immunomodulatory agents; however, no immunomodulator drug has been approved. This multicenter, prospective, open-label, uncontrolled study aimed to assess the use of subcutaneous tocilizumab in adult patients with severe and critical COVID-19. Tocilizumab was added to the standard care of therapy at a dose of 324 mg (<100 kg bodyweight) or 486 mg (≥100 kg bodyweight). The study endpoints were all-cause mortality rate, changes in oxygen-support level, oxygen saturation, body temperature, respiratory rate, and laboratory variables during the study, and drug safety. Of 126 patients enrolled, 86 had severe and 40 had critical disease. Most patients were male (63.49%) and aged below 65 (78.57%). By day 14 of the study, 4.65% (4/86) of severe patients and 50.00% (20/40) of critical patients died. By the end, 6.98% (6/86) of severe patients and 60.00% (24/40) of critical patients died.Outcomes concerning three additional endpoints (oral temperature, oxygen saturation, and respiratory rate)were significantly improved as early as three days after tocilizumab administration in both groups of subjects, more considerably in severe patients. Significant improvement in the required level of oxygenation was reported in severe patients seven days after tocilizumab administration. No tocilizumab-related serious adverse event occurred in this study. Subcutaneous tocilizumab might improve some clinical parameters and reduce the risk of death in COVID-19 patients, particularly if used in the early stages of respiratory failure.

PURPOSE: To evaluate ocular findings in patients with Coronavirus Disease 2019 (COVID-19) in the Northeast of Iran. METHODS: In a cross-sectional, observational study all consecutive patients with confirmed COVID-19 diagnosis at the central referral center of these patients in northeast of Iran were included. Ocular examinations (external and slit) were randomly performed for the patients who were admitted to the Intensive Care Unit (ICU) and six COVID wards of the hospital. Moreover, Chart records and serum chemistry results were collected. RESULTS: A total of 142 patients with the mean age of 62.6 ± 15 years (range: 23-96 years) and almost equal gender distribution (male: N = 77, 54.2%) were included in the study. During the initial external examination by the ophthalmologist, 44 (31%) patients were found to have conjunctival hyperemia and 22 (15.5%) patients had chemosis. Consecutive slit examination showed 41 (28.9%) conjunctival hyperemia, 22 (15.5%) chemosis, 11 (7.7%) cataract, and 9 (6.3%) diabetic retinopathy. The patients with at least one ocular manifestation had significantly higher blood urea levels at the time of admission compared to those with no obvious ocular involvement (median: 41.5, IQR: 28-66.3 vs. median: 33, IQR: 23.8-51.8, P = .023). Moreover, a significant difference was observed in the total white blood cell count, lymphocyte percent, neutrophil count, Erythrocyte Sedimentation Rate (ESR), and blood urea level between patients with positive and negative Polymerase Chain Reaction (PCR) for SARS-CoV-2 virus. None of the patients reported ocular symptoms prior to systemic involvement. The proportion of patients with at least one ocular manifestation was significantly higher in those admitted in the ICU compared to the non-ICU wards. wards. While conjunctival hyperemia was the most prevalent ocular finding in all patients, chemosis was the most common ocular manifestation in ICU admitted patients. CONCLUSION: Ocular manifestation was observed in more than half of our COVID-19 patients. Hence, it seems important to involve ophthalmologist in the diagnosis and management of these patients.
