'Patera syndrome' during the COVID-19 pandemic in the Canary Islands (Spain).

BACKGROUND

The number of migrants arriving on the shores of the Canary Islands continues to increase. The conditions under which the crossing is made, in small crowded, unsanitary boats (pateras or cayucos), have many and significant health problems.

OBJECTIVE

To describe the demographic, clinical, microbiological characteristics and evolution of a series of patients who recently arrived by patera and required hospitalization.

PATIENTS AND METHODS

This observational, cross-sectional, and retrospective study included all patients newly arrived in Gran Canaria (Spain) by patera or cayuco from 2020 to 2022. Acute patera syndrome (APS) was defined as one or more of the following: dehydration, hypothermia, shock or rhabdomyolysis. Skin and soft tissue or musculoskeletal patera syndrome (SSTMSPS) was defined as conditions characterized by lesions of the skin, subcutaneous tissue, bone, or joint, excluding superficial erosions.

RESULTS

During the study period, 193 migrants were admitted, mostly males with a median age of 23 years from West Africa. A total of 36.99% presented with APS with a single diagnostic criterion (most commonly dehydration, 86.9%), 11.56% with SSTMPS and 51.44% with both syndromes. A total of 109 patients presented with SSTMSPS, the most common being lower extremity ulcers. The most frequently isolated microorganisms were gram-negative (i.e. Shewanella algae). The McMahon score effectively predicted the need for renal replacement therapy in cases of rhabdomyolysis. Twenty patients presented with pneumomediastinum, which was benign. SARS-CoV-2 infection was not a problem in any of them. Surgical intervention was required in 22% of cases, including 8 amputations, all of which were minor. No patient died during admission.

CONCLUSION

Patera syndrome has specific characteristics that should be identified promptly to initiate the most effective treatment for optimal outcomes.
