Multisystem inflammatory syndrome in adults following COVID-19 infection: A case report presenting with colitis.

BACKGROUND: Multisystem Inflammatory Syndrome in Adults (MIS-A) is a recently emerging condition that occurs as a delayed complication of COVID-19 infection. It involves inflammation of multiple extra-pulmonary organ systems. Diagnostic criteria and treatment recommendations have yet to be clearly defined. We present a case of a young adult with suspected MIS-A who initially displayed symptoms and radiological findings of colitis.Case: A 22-year-old male with no past medical history suffered a minor respiratory illness for a few days and tested positive on SARS-CoV-2 RT-PCR. Approximately 6 weeks later, he presents after 3 days of right-sided abdominal pain, diarrhoea and fever. He is initially admitted with a working diagnosis of gastroenteritis. Sustained fever and escalating blood markers of illness led to abdominal CT; showing inflammation of ascending colon as well as some loops of small bowel. Hypotension becomes increasingly pronounced and on the fourth day of admission he developed type 1 respiratory failure with evidence of fluid overload. He was transferred to critical care for vasopressor and respiratory support. All microbiological and autoimmune screens performed return negative results but inflammatory markers were significantly elevated, he was diagnosed as MIS-A. IVIg was added to the antibiotics on day 4. His clinical condition dramatically improved and he was discharged home after 10 days in hospital. His blood tests have returned to normal and he has no lasting complications from his illness. DISCUSSION: This case displays the potential for MIS-A to present in various ways, with this example a primarily gastroenterological illness. It therefore highlights the importance of physicians in different fields having an awareness of the condition, in order to identify when MDT input is required to guide treatment. We review the current literature on various presentations and treatments of MIS-A, and discuss the need for clear case definition.

Tuberculosis diagnosis cascade in Blantyre, Malawi: a prospective cohort study.

BACKGROUND: Tuberculosis (TB) control relies on early diagnosis and treatment. International guidelines recommend systematic TB screening at health facilities, but implementation is challenging. We investigated completion of recommended TB screening steps in Blantyre, Malawi. METHODS: A prospective cohort recruited adult outpatients attending Bangwe primary clinic. Entry interviews were linked to exit interviews. The proportion of participants progressing through each step of the diagnostic pathway were estimated. Factors associated with request for sputum were investigated using multivariable logistic regression. RESULTS: Of 5442 clinic attendances 2397 (44%) had exit interviews. In clinically indicated participants (n = 445) 256 (57.5%) were asked about cough, 36 (8.1%) were asked for sputum, 21 (4.7%) gave sputum and 1 (0.2%) received same-day results. Significant associations with request for sputum were: any TB symptom (aOR:3.20, 95%CI:2.02-5.06), increasing age (aOR:1.02, 95%CI:1.01-1.04 per year) and for HIV-negative participants only, a history of previous TB (aOR:3.37, 95%CI:1.45-7.81). Numbers requiring sputum tests (26/day) outnumbered diagnostic capacity (8-12/day). CONCLUSIONS: Patients were lost at every stage of the TB care cascade, with same day sputum submission following all steps of the diagnosis cascade achieved in only 4.7% if clinically indicated. Infection control strategies should be implemented, with reporting on early steps of the TB care cascade formalised. High-throughput screening interventions, such as digital CXR, that can achieve same-day TB diagnosis are urgently needed to meet WHO End TB goals.

Provider-initiated HIV testing and TB screening in the era of universal coverage: Are the right people being reached? A cohort study in Blantyre, Malawi.

INTRODUCTION: Patients with tuberculosis (TB) symptoms have high prevalence of HIV, and should be prioritised for HIV testing. METHODS: In a prospective cohort study in Bangwe primary care clinic, Blantyre, Malawi, all adults (18 years or older) presenting with an acute illness were screened for TB symptoms (cough, fever, night sweats, weight loss). Demographic characteristics were linked to exit interview by fingerprint bioidentification. Multivariable logistic regression models were constructed to estimate the proportion completing same-visit HIV testing, comparing between those with and without TB symptoms. RESULTS: There were 5427 adult attendees between 21/5/2018 and 6/9/2018. Exit interviews were performed for 2402 (44%). 276 patients were excluded from the analysis, being already on antiretroviral therapy (ART). Presentation with any TB symptom was common for men (54.6%) and women (57.4%). Overall 27.6% (585/ 2121) attenders reported being offered testing and 21.5% (455/2121) completed provider-initiated HIV testing and counselling (PITC) and received results. The proportions offered testing were similar among participants with and without TB symptoms (any TB symptom: 29.0% vs. 25.7%). This was consistent for each individual symptom; cough, weight loss, fever and night sweats. Multivariable regression models indicated men, younger adults and participants who had previously tested were more likely to complete PITC than women, older adults and those who had never previously tested. CONCLUSIONS: Same-visit completion of HIV testing was suboptimal, especially among groups known to have high prevalence of undiagnosed HIV. As countries approach universal coverage of ART, identifying and prioritising currently underserved groups for HIV testing will be essential.

An evaluation of 1 year of advice calls to a tropical and infectious disease referral Centre.

OBJECTIVES: Many secondary care departments receive external advice calls. However, systematic advice-call documentation is uncommon and evidence on call nature and burden infrequent. The Liverpool tropical and infectious disease unit (TIDU) provides specialist advice locally, regionally and nationally. We created and evaluated a recording system to document advice calls received by TIDU. METHODS: An electronic advice-call recording system was created for TIDU specialist trainees to document complex, predominantly external calls. Fourteen months of advice calls were summarised, analysed and recommendations for other departments wishing to replicate this system made. RESULTS: Five-hundred and ninety calls regarding 362 patients were documented. Median patient age was 44 years (interquartile range 29-56 years) and 56% were male. Sixty-nine per cent of patients discussed were referred from secondary healthcare, half from emergency or acute medicine departments; 43% of patients were returning travellers; 59% of returning travellers had undifferentiated fever, one-third of whom returned from sub-Saharan Africa; 32% of patients discussed were further reviewed at TIDU. Interim 6-month review showed good user acceptability of the system. CONCLUSIONS: Implementing an advice-call recording system was feasible within TIDU. Call and follow-up burden was high with advice regarding fever in returned travellers predominating. Similar systems could improve clinical governance, patient care and service delivery in other secondary care departments.

Lessons learned from an under-reported mumps epidemic among Rohingya refugees in Cox's Bazar District, Bangladesh.

BACKGROUND: In 2018, a large mumps epidemic coincided with an outbreak of diphtheria in refugee camps established in Bangladesh for the Rohingya people. These refugees did not receive a mumps-containing vaccine. METHODS: Cases of mumps were reported to the WHO's Early Warning, Alert and Response System (EWARS) during the Rohingya refugee crisis. The authors present amalgamated epidemiological data of a major, previously under-reported, mumps epidemic. RESULTS: In total, 19 215 mumps cases across a total of 218 facilities were reported to EWARS during 2018. The attack rate was 2.1% of the whole population. Of these cases, 7687 (40%) were in children aged <5 y. Mumps was more commonly seen among males than females. CONCLUSION: Detailed reporting of outbreaks of all vaccine-preventable diseases is essential to ensure appropriate vaccination decisions can be made in future humanitarian crises.

Prevalence of chronic hepatitis B in Oro Province, Papua New Guinea.

Chronic hepatitis B (CHB) affects over 250 million people worldwide. In Papua New Guinea, the prevalence of CHB has been estimated to be over 8%, and it is a leading cause of death. To address this problem, an alliance was formed between the government of Oro Province, a large private employer and an Australian nongovernmental organization, which established a CHB test and treatment programme. Between 2014 and 2019, rapid hepatitis B surface antigen testing was performed on 4068 individuals in Oro Province. The crude prevalence rate was 12.98% and was significantly higher in males (15.26%) than females (10.94%) (P < 0.001). The rate was 4.72% among children aged 10 years and under, 12.81% among women of childbearing age (19-35 years) and 18.48% among health-care workers. These results indicate that the rates of vaccination at birth and later among women of childbearing age and health-care workers must be improved to prevent transmission of CHB.

Assessment of an incidental finding of left bundle-branch block.

Incidental left bundle-branch block occurs in up to 1.5% of healthy adults without symptoms or signs of cardiovascular disease. It may be found during investigation for non-cardiac disease, during preoperative assessment, private health screening or inpatient monitoring. This article outlines how to assess these patients.
