Betalactam hypersensitivity: The importance of delabelling in primary care.

PATIENTS AND METHODS: An allergy work-up was performed on adult patients with a history of a penicillin allergy seen by primary medical care in Monastir (Tunisia) between July 2016 and February 2018. Patients with negative skin tests were challenged with amoxicillin. Patients who were delabelled were contacted by phone after 6 months to determine outcomes after any therapeutic penicillin-class antibiotic intake. RESULTS: A total of 39 patients were evaluated and 33 (84.6%) were delabelled. Five patients were penicillin skin-test positive and one was oral challenge positive. We succeeded in contacting 33 delabelled patients at 6 months. Twenty-two patients tolerated a subsequent therapeutic course of amoxicillin, eight patients did not retake penicillin due to a lack of therapeutic indication, and three patients refused an indicated penicillin use fearful of another reaction. CONCLUSION: This study highlights the importance of allergy work-up in the diagnosis of beta-lactam hypersensitivity. Most patients were excessively labelled as beta-lactam allergic and this mislabelling could increase healthcare costs and lead to the development of drug resistance by the use of wide-spectrum antibiotics.

Hospitalizations for communicable diseases in a developing country: prevalence and trends-Monastir, Tunisia, 2002-2013.

BACKGROUND: In spite of the epidemiological transition, communicable diseases remain a public health problem and represent a significant cause of morbidity and mortality worldwide, especially in developing countries. This study aimed to determine the crude and standardized prevalence rates of hospitalizations for communicable disease (HCD) and to assess trends in HCD by age and sex at a university hospital in Tunisia over a period of 12 years (2002-2013). METHODS: All cases of HCD from 2002 to 2013 in the university hospital departments were included. Data collected from the regional register of hospital morbidity were used. The discharge diagnoses were coded according to the International Classification of Diseases, 10th revision (ICD-10). RESULTS: HCD represented 17.45% of all hospitalizations during the study period (34 289/196 488; 95% confidence interval 17.28-17.62%). The median age at the time of admission was 31 years (interquartile range (IQR) 15-52 years). The median hospital length of stay (LOS) was 5days (IQR 3-9 days). The crude prevalence rate (CPR) was 5.41 per 1000 inhabitants. The CPR was highest among patients aged ≥65 years. The four communicable disease categories that represented 70% of all HCD were abdominal infection, skin infection, genitourinary infection, and lower respiratory tract infection. The majority of HCD decreased over time; however, there was a significant increase in HIV diseases, tuberculosis, and viral hepatitis. CONCLUSION: This study provides evidence of the epidemiological transition, showing a decline in communicable diseases, which needs to be sustained and improved.
