Objective This study aimed to assess clinical outcomes, diagnosis, utilized drug therapies, and ongoing COVID-19 practices in Iranian cases co-infected with COVID-19 and mucormycosis. Participants and methods A case-series analysis was conducted in the presence of 10 patients with COVID-19 and mucormycosis co-infection (two men and eight women; mean age of 48.8 years) from March to October 2020. Demographic variables, signs/symptoms, and comorbidities of all patients were recorded. COVID-19 was confirmed with reverse transcription polymerase chain reaction (RT-PCR) nasopharyngeal swab tests and high-resolution computed tomography (HR-CT)_ scans. Results All patients had a positive RT-PCR for SARS-CoV-2. Eight patients had a history of diabetes, while three of them exhibited a hypertension history. Remarkable laboratory findings were elevated fasting blood sugar in 6 cases and anaemia in four patients. A rhino-orbital-cerebral of mucormycosis in all patients was detected based on HR-CT scans and otorhinolaryngological or ophthalmological examinations. Neurological disorders including facial, trigeminal, optic, and oculomotor nerve involvement resulted in paraesthesia, pain, ptosis, no light perception, blurred vision, and papilledema in five cases. Maxillary and ethmoid sinuses were the most common sites of involvement. Conclusion Vulnerable COVID-19 patients with comorbidities, any facial involvements, or treated by excessive doses of glucocorticoids and antibiotics should undergo precise examinations during the appearance of early signs and hospitalization to diagnose and treat mucormycosis using the standard care and antifungal treatments.","PeriodicalId":13671,"journal":{"name":"Infectious Diseases","volume":"54 1","pages":"600 - 613"},"PeriodicalIF":5.8,"publicationDate":"2022-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45056327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patients were being seen for evaluation of possible tick-borne infections primarily tick-borne encephalitis and Lyme disease. The reason for carrying out assays for IgE to a -gal was because of recognition that in many areas of the world tick bites can induce sensitisation to this oligosaccharide which in turn is associated with an unusual form of delayed allergic reactions to red meat [2]. The results show a significant association between a history of tick bites and IgE to a -gal [3]. In addition, in keeping with previous studies they found no association between evidence of a tick borne infection and positive IgE to a -gal [1,4,5]. Our data on serological evidence of Rickettsial organisms among patients with AGS in two areas of the United States showed a high prevalence of positive sera among patients and controls [6]. The most likely explanation of that result is that the positive serology reflects ‘ infection ’ with Rickettsia amblyomii which is a common symbiont of the Lone Star tick but is not really a pathogen. What matters here is that none of the published results provide evidence that the pathogens carried by ticks con-tribute to a -gal sensitisation.

They cause delayed and immediate allergy to mammalian meat and medication including antivenoms, vaccines and monoclonal antibodies. Methods We assessed the prevalence of α-gal sIgE in forest workers and healthy controls in the Podlasie voivodeship, north-eastern Poland; the relationship between α-gal sIgE and allergy to α-gal-containing products; the correlation between α-gal sIgE and anti-Borrelia burgdorferi and anti-tick-borne encephalitis virus (TBEV) antibodies; the relationship between α-gal sIgE and markers of infection with lesser-known pathogens transmitted by ticks such as Anaplasma phagocytophilum. Results Production of α-gal sIgE was closely related to tick bites. The odds ratio for detectable α-gal sIgE was 9.31 times higher among people with a history of tick bites (OR 9.3; p < .05). There was no correlation with the history of TBE, Lyme disease or human granulocytic anaplasmosis. However, serum α-gal sIgE correlated with anti-TBEV IgM antibodies in CSF. There was a strong correlation between α-gal sIgE and total IgE and sIgE to pork and beef. Conclusions Our data support the link between I.ricinus ticks and the production of α-gal sIgE and confirm that the pathogens carried by ticks we examined for do not seem implicated in this immune response.","PeriodicalId":13671,"journal":{"name":"Infectious Diseases","volume":"54 1","pages":"572 - 579"},"PeriodicalIF":5.8,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44006642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared sex-related associations of inflammation parameters and outcome in a population-based setting with low case-fatality prior to wide use of immunosuppressives. Methods A population-based quality registry with laboratory-confirmed COVID-19 cases of specialized hospitals of the Capital Province of Finland were analysed to compare inflammatory parameters by sex during the first COVID-19 wave February–June 2020. Results Altogether, 585 hospitalized patients (54% males) were included. Males required more often intensive care unit (ICU) treatment (26.9 vs. 17.5%) and had higher 90-d case-fatality (14.9 vs. 7.8%) compared with females. Highest association with case-fatality in males was seen for high neutrophil counts (median; interquartile range) (8.70; 7.10–9.10 vs. 5.60; 3.90–7.80) (E9/l), low monocyte (0.50; 0.20–1.50 vs. 0.70; 0.50–0.90) (E9/l) and lymphocyte (0.90; 0.70-1.40 vs. 1.50; 1.10-2.00) (E9/l) counts, and high levels of d-dimer (3.80; 1.80–5.30 vs. 1.10; 0.60–2.75) (mg/l) and C-reactive protein (CRP) (190; 85.5–290 vs. 77.0; 49.0–94.0) (mg/l). In females, low lymphocyte (0.95; interquartile range 0.60–1.28 vs. 1.50; 1.10–2.00) (E9/l) and thrombocyte counts (196; 132–285 vs. 325; 244–464) (E9/l) and high CRP values (95.0; 62.0–256 vs. 66.0; 42.5–89.0) (mg/l) were associated with case-fatality. In multivariable analysis for males, lymphocyte cut-off 0.85 (E9/l) (OR 0.02; 95% CI 0.002–0.260), d-dimer cut-off 1.15 (mg/l) (OR 7.29; 1.01–52.6) and CRP cut-off 110 (mg/l) (OR 15.4; 1.87–127) were independently associated with case-fatality. In female multivariable analysis, CRP cut-off 81 (mg/l) (OR 7.32; 1.44–37.2) was the only inflammatory parameter associated with case-fatality. Conclusions COVID-19 results in higher inflammation parameter levels in male vs. female patients irrespective of outcome. This study suggests that low lymphocyte, high d-dimer and high CRP cut-off values may serve as potential markers for risk stratification in male patients.","PeriodicalId":13671,"journal":{"name":"Infectious Diseases","volume":"54 1","pages":"558 - 571"},"PeriodicalIF":5.8,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46821996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Case study We present a 28-year-old female living with vertically acquired HIV, undergoing chemotherapy for lymphoma who tested SARS-CoV-2-PCR positive for 164 days. The patient had a history of difficulty taking ARVs, with detectable HIV-RNA and CD4 count below 200 × 106 for the 8 years prior to presentation with symptoms. She stopped ARVs 10 months prior to experiencing fevers, night sweats and loose stool, with a viral load of 354,000 copies/ml and CD4 count of 30 × 106. Following no yield on basic investigations, positron emission tomography scan showed diffuse colonic and oesophageal avidity and a caecal biopsy showed diffuse large B-cell lymphoma. She re-started ARVs and underwent five cycles of R-CHOP chemotherapy. Her first positive SARS-CoV-2 PCR test was detected through routine asymptomatic screening. She self-isolated due to repeated positive tests on a further 8 swabs for a total of 164 days until a negative PCR test. She reported feeling low in mood and frustrated by repeated positive tests and the associated lack of social contact or ability to work. Her positive tests prevented in-person review by her HIV team, which impacted her ARV adherence leading to an unplanned break in therapy.

We describe a previously healthy, 12-year-old boy with new-onset T1DM with diabetic ketoacidosis (DKA) in the setting of MIS-C, with a course complicated by thrombotic microangiopathy. Case presentation The patient presented with four days history of fever, non-bilious vomiting, polyuria and polydipsia. On evaluation, he was noted to have diabetic ketoacidosis. Although Diabetic ketoacidosis with insulin and intravenous fluids, his hospital course was notable for shock requiring vasopressor, purpura fulminans with eschar formation, neurological manifestations (left hemiparesis due to right middle cerebral artery territory infarct, mononeuritis multiplex) and thrombotic microangiopathy. MIS-C-like illness secondary to COVID-19 was suspected due to diabetic ketoacidosis, thrombotic microangiopathy, elevated inflammatory markers, history of contact with COVID-19-infected individual and detectable COVID-19 IgG antibodies.

Since current guidelines do not recommend psychiatric follow-up in all children, disabilities are often detected late. Identifying children with elevated risk of psychiatric disabilities using predictive scores could be one strategy for detecting psychiatric disabilities without having to conduct psychiatric evaluations in all children. Therefore, we searched for existing predictive scores and later tested five predictive scores’ ability to predict psychiatric disabilities following childhood bacterial meningitis. Methods From an existing dataset, we selected 73 children with bacterial meningitis of whom 22 later developed psychiatric disease and 15 experienced concentration or learning difficulties. Using these, we tested each predictive score’s sensitivity at their cut-off level for predicting psychiatric disease and concentration or learning difficulties using a chi-square test. Furthermore, we performed a receiver operating characteristic curve (ROC) analysis to assert the area under the curve (AUC) as a measure of overall predictive performance. Results The sensitivity of each predictive score’ ranged from 6 to 38% for psychiatric disease and from 8 to 57% for concentration or learning difficulties. In the ROC-analysis, the AUC was 0.59–0.73 and 0.53–0.72, respectively. Conclusions All predictive score failed at identifying children later developing psychiatric disabilities, excluding this as a feasible strategy for detecting psychiatric disabilities.
