We present a case of intussusception with complete small bowel obstruction caused by intestinal anisakidosis requiring surgical resection. A 30-year-old man presented with acute onset of severe abdominal pain 3 days after eating home-cured salmon gravlax. Despite surgery, the patient developed recurrent abdominal pain on two occasions with evidence of continued inflammation proximal to the surgical anastomosis. He was then treated with albendazole and prednisone, and symptoms improved. A decision was made to prophylactically treat two asymptomatic family members who also consumed home-cured gravlax with albendazole, resulting in one individual passing an intact Anisakis worm in her stool. We suggest that albendazole therapy could be considered as a therapy for continued symptoms of anisakidosis and postexposure prophylaxis of Anisakis larvae ingestion from a common source.

Background

The transition between inpatient and outpatient care for hospitalized people with HIV represents an opportunity for linkage and re-engagement in care. We evaluated whether attendance at a post-hospitalization visit ('discharge clinic') within 1-2 weeks of discharge would reduce readmissions and improve retention in care (RIC) among people with HIV in San Diego, California, USA.

Methods

This was a retrospective cohort study of people with HIV hospitalized between June 2020 and November 2021. Our primary outcome was 30-day readmissions among people with HIV who did or did not attend a discharge clinic visit. Secondary outcomes included the effect of discharge clinic attendance on RIC, along with the impact of attendance at any HIV clinic visit within 30 days of discharge on readmissions and RIC.

Results

We evaluated 114 people with HIV, of whom 77 (67.5%) and 90 (78.9%) attended a discharge clinic visit or any HIV clinic visit within 30 days of discharge, respectively. Active substance use disorder (SUD) was associated with failing to attend a discharge clinic visit (odds ratio 0.31; 95% confidence interval 0.13-0.77). We observed no significant differences in readmissions between people with HIV who did or did not attend a discharge clinic visit; however, the former had significantly higher 6-month RIC (79.2% vs. 35.1%, p < 0.001). People with HIV attending any HIV clinic visit within 30 days of discharge had significantly fewer 30-day readmissions (8.9% vs. 29.2%, p = 0.02) and better 6-month RIC (75.6% vs. 25%, p < 0.001) than those who did not attend.

Conclusion

Early hospital follow-up care was associated with a reduction in readmissions among people with HIV. Active SUD was a significant barrier to linkage to outpatient follow-up and RIC.

Study objectives

Many people living with human immunodeficiency virus (PLWH) have undiagnosed obstructive sleep apnea (OSA), which may contribute to commonly reported fatigue and the high cardiovascular disease burden in this population. Our objective was to assess the utility of traditional OSA screening tools (STOP-BANG, Berlin Questionnaire, and Epworth Sleepiness Scale) for detecting OSA in PLWH.

Methods

Adult PLWH were recruited from sleep/ human immunodeficiency virus clinics and the community into a larger clinical trial that included completion of these questionnaires before in-laboratory polysomnography. Discriminatory performance of these screening tools was assessed using area under receiver operating characteristic curves (AUC). The reference standard for the primary analysis was OSA based on an apnea-hypopnea index ≥ 5 events/h using recommended "1A"-criteria (hypopnea with 3% desaturation and/or arousal). Secondary analyses explored acceptable "1B"-criteria (hypopnea with 4% desaturation) and/or higher apnea-hypopnea index cut-offs (≥ 15 events/h).

Results

120 PLWH were included (mean age: 50 ± 11 years; body mass index: 27 ± 4 kg/m², 84% male) and OSA was diagnosed in 75% using 1A-criteria. In the primary analysis, the discriminatory performance of the 3 screening tools was low (AUCs 0.58 to 0.70) and similar across the tools (P ≥ .14). In secondary analyses, STOP-BANG showed moderate-high discriminatory ability (AUCs 0.77-0.80) and performed significantly better (P ≤ .008) than the Berlin Questionnaire or Epworth Sleepiness Scale (AUCs 0.53-0.62).

Conclusions

OSA was highly prevalent in our cohort of PLWH. Although STOP-BANG could reasonably identify moderate-severe OSA, the tools were not reliable for mild disease. Specifically, the questionnaires perform poorly for PLWH with mild OSA manifesting with arousals, yet such people may be at risk of fatigue/sleepiness and impaired memory consolidation.
