Tackling late HIV diagnosis: Lessons from the UK in the COVID-19 era.

INTRODUCTION: Late diagnosis of HIV is associated with increased morbidity and mortality, and an increased risk of non-infectious comorbidities. On a societal level, late diagnosis leads to higher treatment and healthcare costs and is a major driver of HIV transmission. Despite improvements in other areas of the HIV care pathway, late diagnosis remains an individual and public health concern globally. OBJECTIVE: To examine the barriers to HIV testing and highlight successful strategies to improve prompt diagnosis. This review describes the prevalence of late diagnosis in the UK and discusses key factors that contribute to late diagnosis, including the effect of the COVID-19 pandemic. Late HIV diagnosis is lower in the UK than in most other European countries. In this review, pilot projects and ongoing initiatives that have reduced late diagnosis in the UK are highlighted; moreover, further strategies for improving prompt diagnosis are suggested. CONCLUSIONS: Insufficient testing is the fundamental reason for late HIV diagnosis, with societal, systemic, and individual factors all contributing to inadequate testing. Improving access to testing, removing barriers to health-seeking behaviour, and ensuring all people with HIV indicator conditions are promptly tested are key to reducing the rates of late diagnosis globally.

A re-audit of individuals with a late diagnosis of HIV in 2016 and 2019 in Greater Manchester.

BACKGROUND: New late HIV diagnosis (CD4 count <350cells/mm3) are higher in North West England compared to the UK average. A Greater Manchester-wide audit into individuals diagnosed with late or very late HIV was conducted in 2016 and re-audited in 2019. Our aim was to gain intelligence into key demographics of late diagnosed individuals across Greater Manchester, review opportunities for earlier diagnosis and determine if key recommendations from the 2016 audit were followed. METHODS: Individuals were identified from locally kept data or HIV and AIDS Reporting System (HARS) data. A retrospective case note review was performed for each patient using data from local notes, General Practice summary of care records and relevant clinical letters. Data was collected for 2019 and compared to 2016 results. RESULTS: In 2016, nine departments contributed data and 104 individuals were identified as having been diagnosed late. In 2019, seven departments contributed data and 65 individuals were identified as having been diagnosed late. In both years, a greater proportion of males diagnosed late were White British and for females Black African. A greater proportion of late diagnosis occurred in men who have sex with men (MSM) and in heterosexual females. In 2019, a greater proportion of patients had an AIDS-defining illness at time of diagnosis. Whilst in 2016, most patients were asymptomatic. Over one third of patients had a clinical indicator disease in their past medical history, which is an increase in proportion from 2016. The proportion of cases where clinicians felt that there had been probable missed opportunities for earlier diagnosis also increased in 2019. CONCLUSIONS: There are continued missed opportunities for earlier diagnosis. We recommend targeted interventions for groups at higher risk of late presentation, education in primary/secondary care regarding clinical indicator conditions, a formal review process for all late diagnosed cases, communication with primary/secondary care if missed opportunities are identified and broader HIV testing especially in high prevalence areas.

A rare case of HIV encephalopathy presenting with an isolated cerebellar syndrome.

Cerebellar dysfunction is a well-recognised but an infrequent complication of human immunodeficiency virus (HIV) infection. We present the case of a 44-year-old man living with HIV who presented with subacute cerebellar dysfunction and in whom a thorough diagnostic work-up did not identify any opportunistic infections. Cerebrospinal fluid (CSF) analysis showed a high HIV viral load of 1160 copies/ml and magnetic resonance imaging (MRI) showed multiple high signal abnormalities, disproportionately affecting the posterior fossa especially the cerebellum. This is a rare case of HIV encephalopathy presenting with an isolated cerebellar syndrome and highlights the importance of considering HIV as the aetiology in this clinical scenario.

Goodpasture's disease with late presentation of renal abnormality and anti-GBM autoantibody.

Goodpasture's disease without circulating autoantibodies is a rare presentation of a rare diagnosis. We present the case of a man aged 17 years who had 3 hospital admissions over a 2-month period with haemoptysis and shortness of breath. Throughout his first 2 admissions, his renal function was normal and anti-glomerular basement membrane (GBM) antibodies were negative. CT pulmonary angiogram during his second admission revealed florid and diffuse alveolar infiltrates. However, high-resolution CT chest performed 4 weeks later showed complete resolution of these changes. On his third admission, he developed acute kidney injury. A repeat CT chest revealed the reappearance of initial findings and anti-GBM antibodies were now positive. Goodpasture's disease was subsequently confirmed with renal biopsy. Our case, with delayed onset of renal impairment, initial seronegativity for anti-GBM antibodies and relapsing and remitting CT findings, emphasises the need to consider this diagnosis in the setting of otherwise unexplained pulmonary haemorrhage.
