RESUMEN
Recently, cases of fortuitous discovery of Chronic Lymphocytic Leukemia (CLL) during hospitalization for Coronavirus disease (COVID-19) have been reported. These patients did not show a monoclonal B cell expansion before COVID-19 but were diagnosed with CLL upon a sudden lymphocytosis that occurred during hospitalization. The (hyper)lymphocytosis during COVID-19 was also described in patients with overt CLL disease. Contextually, lymphocytosis is an unexpected phenomenon since it is an uncommon feature in the COVID-19 patient population, who rather tend to experience lymphopenia. Thus, lymphocytosis that arises during COVID-19 infection is a thought-provoking behavior, strikingly in contrast with that observed in non-CLL individuals. Herein, we speculate about the possible mechanisms involved with the observed phenomenon. Many of the plausible explanations might have an adverse impact on these CLL patients and further clinical and laboratory investigations might be desirable.
RESUMEN
Campylobacteriosis is caused by Gram bacteria. Most common species are C. jejuni and C. coli. Campylobacteriosis is a rare cause of sepsis, and in some European countries it is more common than salmonellosis, becoming a public health problem. We have treated a 66-year-old patient, hypertensive, ischemic cardiopathic, scheduled for coronary angiography, hospitalized with AKI, in a state of shock after some days of acute diarrhea. Because of the pathogen's seasonal nature and the patient's clinical features, in addition to common coproculture also Campylobacter has been sought, and found. Treated with volume repletion and antibiotics, within one week normal kidney functions were fully restored. He had a coronary angiography a week after being discharged from the hospital.
