Central nervous system effects (delirium, tremor, dizziness and occasional seizures in 5%–12%), especially in older people. Reduces clearance of xanthines and theophyllines, potentially inducing insomnia and increased seizure potential. Prolongation of QT interval on ECG, cardiac arrhythmias.

Paromomycin is an aminoglycoside that is used to treat visceral leishmaniasis and intestinal amoebiasis. It is not significantly absorbed when administered orally, and is therefore given orally for intestinal amoebiasis and by intramuscular injection for leishmaniasis. It showed early promise in the treatment of HIV-associated cryptosporidiosis but subsequent trials have demonstrated that this effect is marginal at best.

54-year-old woman presents to the emergency department with fevers and a sore throat. She has recently been diagnosed with left-sided breast cancer and associated axillary lymph node disease. Twelve days ago she received her first cycle of neoadjuvant cytotoxic chemotherapy (5-uorouracil, epirubicin and cyclophosphamide). On clinical examination, her temperature is 38.3°C; she appears dehydrated and there is evidence of oral candidiasis. An intravenous catheter is placed and bloods, including blood cultures, taken. What is the most appropriate next step in this patient’s care?
ক
Perform a chest X-ray, collect a urine sample and throat swab to complete the infection screen
খ
Start intravenous opioids
গ
Await blood test results to inform further management
The clinical features here are of fever in a patient at high risk of neutropenia. This is an oncological emergency. Patients are at risk of neutropenia at any point during their systemic anti-cancer therapy treatment cycle, with the highest risk typically 10–14 days after a treatment. In patients with potential neutropenic sepsis high-dose broad spectrum intravenous antibiotics should be commenced, ideally within 1 hour of admission, without awaiting test results. In this should not delay the first dose of antibiotic therapy. Test results may later inform changes to antimicrobial therapy and its duration.
