ABSTRACT

Selective immunoglobulin A (IgA) deficiency (IgAD) is the most common primary immunodeficiency in the western world. The aim of the study was to investigate the prevalence and clinical characteristics of Helicobacter pylori-infected dyspeptic patients with IgAD. Case samples were drawn from all subjects ≥ 12 years of age (n = 104729) who had undergone serum total IgA measurements during 2004-14 for any reason at Leumit Healthcare Services (Israel) and had serum total IgA < 0·07 g/l. The control group was comprised of a random sample of remaining patients with a case-control ratio of 10 controls for each case. The dyspeptic diseases were identified and retrieved from Leumit Health Care Services electronic database using specific ICD-9-CM diagnostic codes. The case group included 347 subjects and the control group 3470 subjects. There were no significant differences in the prevalence of patients with dyspepsia [84 (24·2%) versus 821 (23·6%) for cases and controls, respectively]. Additionally, there was no difference in a proportion of dyspeptic H. pylori-positive subjects [59 (17·1%) versus 524 (15·1%)] between the case and control groups. Only 59 (17%) among the 347 IgAD patients underwent gastroscopy. A significantly larger proportion of case subjects experienced several forms of gastritis [13 (61·9%) versus 38 (21·6%), P < 0·001), duodenal ulcers [seven (33·3%) versus 19 (10·8%); P = 0·01] and nodular lymphoid hyperplasia (NLH) [two (9·5%) versus none; P = 0·011]. IgAD is not associated with increased prevalence of H. pylori-associated dyspepsia; nevertheless, H. pylori-infected dyspeptic IgAD subjects experience more EGD-proved gastritis, duodenal ulcers and NLH.

ABSTRACT

CONTEXT: Trimethoprim-sulfamethoxazole (TMP-SMX) and nitrofurantoin were until recently the two drugs recommended in clinical guidelines in Israel for empiric treatment of uncomplicated urinary tract infection (UTI) in women. OBJECTIVES: The objective of this study is to evaluate the economic impact of physician non-adherence to these recommendations. DESIGN SETTING AND PATIENTS: Data were derived from the electronic patient records of the Leumit Health Fund. Cases of women aged 18 to 75 with a diagnosis of acute cystitis or UTI that were empirically treated with antibiotics from January 2001 to June 2002 were identified. The final sample comprised 7738 physician-patient encounters. The proportion of cases treated with each individual drug was calculated, and the excess expenditure because of non-adherence to guidelines from the perspective of the Health Maintenance Organization (HMO) was evaluated using 5 days of therapy with nitrofurantoin as the reference treatment. RESULTS: TMP-SMX was the most frequently prescribed drug (25.81%), followed by nitrofurantoin (14.71%) representing a 40.52% rate of adherence to the guidelines. Drugs from the fluoroquinolone family were prescribed in 22.82% of cases. Cost of treatment in approximately 70% of the cases exceeded the expected cost of the guideline therapy. CONCLUSIONS: Suboptimal adherence to the guidelines resulted in a significant and avoidable waste of the health plan's resources in both drugs and money.

ABSTRACT

CONTEXT: Current Israeli guidelines for the empiric treatment of uncomplicated urinary tract infection (UTI) in women recommend nitrofurantoin for 5 days. Some physicians nevertheless opt for ofloxacin, which should be prescribed for 3 days according to universally accepted guidelines. OBJECTIVE: To evaluate the economic consequences of longer than recommended durations of antibiotic therapy in the empiric treatment of uncomplicated UTI in women. DESIGN, SETTING AND PATIENTS: Data were derived from the electronic records of one of the four health maintenance organizations in Israel. The sample included all women aged 18-75 years who were diagnosed with acute cystitis or UTI from January 2001 to June 2002 and were empirically treated with antibiotics. Of the 7738 patients identified, 1138 received nitrofurantoin and 1054 ofloxacin. The excess expenditure accrued due to longer than recommended therapy with these drugs was evaluated. RESULTS: The rate of adherence was 22.23% for nitrofurantoin (95% CI=19.81%, 24.65%), and 4.08% for ofloxacin (95% CI=2.88%, 5.28%). The average excess expenditure per case was 5.78 USD (US Dollar) with ofloxacin and 3.43 USD with nitrofurantoin, resulting in an annual loss to the health maintenance organizations of approximately 19,000 USD. When extrapolated to the national population of 6.5 million, the loss due to inappropriate treatment of adult women is 190,000 USD. CONCLUSIONS: The lack of adherence to national and international guidelines with regard to the recommended duration of antibiotic treatment of UTI in women resulted in a significant and avoidable waste of health system resources. This study suggests that drug utilization analyses that concentrate solely on the choice of drug may be overlooking important information.
