The family history in family practice: a questionnaire study

OBJECTIVES: Our aims were to investigate family medical history taking in general practice, and to evaluate the value attached to the family medical history as an aid to decision making in general practice. METHOD: A postal questionnaire survey was conducted among all 291 GPs working within the Calderdale and Kirklees Health Authority area. Each questionnaire was followed by a reminder. The main outcome measures were answers to questions on routine and opportunistic family history taking and a question about transmitting knowledge about genetic risk to other members of the family. Questions were also posed about the value attached to the family medical history as an aid to decision making. RESULTS: A total of 193 GPs returned the questionnaire (response rate 66.3%). On registration, 94.3% of GPs indicated that enquiries were made about a family history of coronary heart disease. Breast and colorectal cancer were specifically asked about by 48.4% and 30.7% of GPs, respectively. One-fifth of respondents indicated that they asked a general question about family medical history. A little over one-quarter of respondents indicated that they made opportunistic enquiries about the family history or suggested that the patient should inform other members of the family about possible risks. In the scenarios highlighted in this study, the majority of respondents felt that the family medical history had value as an aid to decision making. This was particularly the case for checking a patient's cholesterol (92.1%) and for initiating referrals in younger patients with possible cancer-related symptoms (three-quarters of respondents). CONCLUSION: GPs value the family medical history as an aid to decision making. Unfortunately, apart from enquiries about coronary heart disease, routine or opportunistic family history taking is not occurring in practice. Mechanisms need to be sought to extract information from the family medical history so that it can be more effectively used by GPs.      

Lyme disease—another transfusion risk?

Lyme disease (or Lyme borreliosis) is caused by a spirochetal bacteria, Borrelia burgdorferi. Increased recognition of the disease and increased exposure to the vector (ticks) capable of spreading B. burgdorferi from animal hosts have resulted in a rise in the number of cases of Lyme borreliosis reported in the United States. There are three stages of the clinical course of Lyme borreliosis; however, not all those infected will have typical manifestations of each stage, such as the arthritis of the third stage. Routine blood cultures will rarely document bacteremia and serologic testing is not yet reliable. Early treatment can prevent later stages of Lyme borreliosis. There is evidence that transmission of B. burgdorferi by blood transfusion is possible, but, to date, there has been no documentation of transfusion- associated Lyme borreliosis. Thus, no new recommendations for screening donors to identify possible carriers of B. burgdorferi are suggested at this time.     

Diagnostic accuracy, internal consistency, and convergent validity of the Greek version of the patient health questionnaire 9 in diagnosing depression in rheumatologic disorders

Objective

The Patient Health Questionnaire 9 (PHQ‐9) was developed to screen for depressive disorders in community, primary care, and medical settings. We aimed to estimate its diagnostic accuracy, internal consistency, reliability, and convergent validity in diagnosing major depressive disorder (MDD) in Greek patients with rheumatologic disorders.

Methods

In a 2‐phase sampling design study, we recruited 475 patients with established rheumatologic disorders. One of 2 of the high scorers (PHQ‐9 score ≥9, n = 85) and 1 of 3 of the low scorers (PHQ‐9 score 0–8, n = 128) were interviewed using the Mini International Neuropsychiatric Interview to confirm MDD. A receiver operator characteristic curve analysis was performed to confirm the optimum threshold value. The scale's dimensional structure was tested with factor analysis, and internal consistency reliability was assessed with Cronbach's alpha. Psychological distress (Symptom Check List‐90‐Revised [SCL‐90‐R]), disability (Health Assessment Questionnaire disability index), and health‐related quality of life (HRQOL; World Health Organization Quality of Life Instrument [WHOQOL‐BREF]) were also assessed to test convergent validity with bivariate correlations.

Results

At an optimum threshold of 10, the PHQ‐9 showed a sensitivity of 81.2% and a specificity of 86.8%. The area under the curve was 0.91. The PHQ‐9 presented unidimensional structure with good scale reliability (α = 0.82). The PHQ‐9 score presented the greatest correlations with SCL‐90‐R depression (r = 0.736) and WHOQOL‐BREF mental HRQOL scales (r = ?0.571), and all other correlations with disability and HRQOL were in the expected direction.

Conclusion

At a cutoff of 10, the PHQ‐9 is an accurate, reliable, and valid measure for screening for MDD among Greek rheumatologic patients.

     

Unmet needs in the treatment of rheumatoid arthritis. An observational study and a real-life experience from a single university center

Objectives

To estimate the size of unmet needs in the treatment of early Rheumatoid Arthritis (eRA), using all the conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and/or biological DMARDs (bDMARDs) in a long-term observational study.

Circannual variation in lymphocyte subsets, revisited

BACKGROUND: Circadian and circannual variations in lymphocyte subsets, especially CD8+ T-lymphocytes, have been reported. This study focuses on CD4+ T-lymphocyte seasonal variation over a 6-year 8-month period. STUDY DESIGN AND METHODS: Lymphocyte subsets were quantitated monthly for four healthy individuals from 1986 through 1992 as part of a flow cytometry quality-control program. RESULTS: In general, there were no significant seasonal changes in the total number of white cells or in total lymphocyte counts. The absolute numbers of CD4+ T-lymphocytes were lowest in summer when the CD8+ T-lymphocytes were highest. Mean CD4+ T-lymphocyte counts were 846, 967, 618, and 695 per microL for Subjects 1 through 4, respectively, in winter and 432, 670, 355, and 766 per microL, respectively, in summer. Two healthy subjects had CD4+ T-lymphocyte counts lower than 300 per microL on one or more occasions during the study period. In three of the four subjects, the percentage of B-lymphocytes in winter was almost double that in summer. In one of the four subjects, no circannual rhythm was observed in these lymphocyte subpopulations. CONCLUSION: The seasonal variation in CD4+ T- lymphocyte counts demonstrated in three healthy individuals over almost 7 years is again of interest in light of renewed consideration of using surrogate tests, such as CD4+ T-lymphocyte counts, to screen for AIDS- like diseases that may be in the blood supply.     

Outbreak Caused by an Ertapenem-Resistant,CTX-M-15-Producing Klebsiella pneumoniae Sequence Type 101 Clone Carrying an OmpK36 Porin Variant

Although numerous studies have documented outbreaks of carbapenem-resistant Klebsiella pneumoniae (CRKP) possessing various carbapenemases, reports on outbreaks due to CRKP possessing extended-spectrum β-lactamases (ESBLs) and/or AmpCs with porin lesions have been limited. Here, we describe an outbreak caused by an ertapenem-resistant, CTX-M-15-producing clonal K. pneumoniae strain expressing an OmpK36 porin variant. From May 2012 to November 2012, 37 ertapenem-resistant K. pneumoniae isolates phenotypically negative for carbapenemase production were recovered from 19 patients hospitalized in the intensive care unit of a Greek hospital. The isolates were either susceptible or intermediate to other carbapenems and resistant to all remaining β-lactams but cefotetan. Phenotypic and molecular analysis revealed the presence in all isolates of the bla_CTX-M-15 gene on a conjugative 100-kb plasmid, disruption in the expression of the ompK35 gene, and the production of an Ompk36 porin variant. The index case was a patient admitted from another hospital. Active surveillance upon admission and on a weekly basis was immediately initiated; environmental samples were also periodically tested. Molecular typing showed that all clinical isolates as well as two ertapenem-resistant environmental K. pneumoniae isolates belonged to the same clonal type and were assigned to multilocus sequence typing (MLST) sequence type 101 (ST101). As all colonized/infected patients were hospitalized during overlapping periods, cross-infection was considered the main route for the dissemination of the outbreak strain. Despite reinforcement of infection control measures and active surveillance, the outbreak lasted approximately 7 months. Identification of hidden carriers upon admission and by screening on a weekly basis was found valuable for early recognition and subsequent successful management of the outbreak.     

ABP 501 for the treatment of rheumatoid arthritis

Introduction: Rheumatoid arthritis (RA) is an autoimmune disease, which has a negative impact on the ability to perform activities daily. Tumour necrosis factor α (TNF) is a cytokine with diverse cellular effects, and a key regulator of the inflammatory response. ABP 501 is a biosimilar to adalimumab, a TNF inhibitor.

Areas covered: In this review, we examined ABP 501, as a biosimilar candidate to adalimumab in the treatment of RA focusing on the available data. Current data indicate that ABP 501 is a highly similar alternative to adalimumab in terms of safety, efficacy, tolerability and immunogenicity. ABP 501 has already been approved by health authorities in Europe and the United States of America, as a subcutaneous (s.c.) therapy option for the treatment of patients with RA, but also for the full spectrum approved for its bio-originator adalimumab.

Expert opinion: Current body of evidence suggests that all biologic activities have been demonstrated to be equivalent between ABP 501 and the originator, including binding rates and affinity to TNF, and also the effector functions such as antibody-dependent cell-mediated cytotoxicity (ADCC). Therefore, it is fully expected to have same efficacy and safety in all indications.
