The effectiveness of nitrofurantoin, fosfomycin and trimethoprim for the treatment of cystitis in relation to renal function

Objectives: We evaluated the effect of renal function on clinical failure rates of nitrofurantoin, fosfomycin and trimethoprim for the treatment of cystitis in primary care. Methods: Data were retrospectively obtained from 78 Dutch general practitioner (GP) practices between 2013 and 2019. Eligible episodes in patients (>11 years) were those requiring 5 days of nitrofurantoin (NF5), single-dose fosfomycin–trometamol (FT1), 3 days of trimethoprim (TMP3) for uncomplicated cystitis, or 7 days of nitrofurantoin (NF7) or trimethoprim (TMP7) for complicated cystitis. Clinical failure was defined as second antibiotic prescription for cystitis or pyelonephritis within 28 days post-prescription. Mixed effects regression analysis was used, with patient and GP practice as random effects and demography, comorbidity, and cystitis history as fixed effects. Results: Adjusted odds ratios (aORs) for clinical failure per 10mL/min decrease in estimated glomerular filtration rate (eGFR) were 1.05 (95% CI: 1.01–1.09) for NF5 (n = 24,591), 0.96 (95% CI: 0.92–1.01) for FT1 (n = 5359), 0.98 (95% CI: 0.89–1.08) for TMP3 (n = 1064), 1.05 (95% CI: 1.02–1.09) for NF7 (n = 10,628) and 1.02 (95% CI: 0.93–1.14) for TMP7 (n = 831). In uncomplicated cystitis and eGFR ≥60 mL/min, clinical failures occurred in 14.6% (1895/12 980) of NF5-treated, 20.7% (266/1283) of FT1-treated (aOR versus NF5 1.37, 95% CI 1.18–1.59) and 20.8% (66/318) of TMP3-treated patients (aOR 1.42, 95% CI 1.07–1.87 versus NF5). In uncomplicated cystitis and eGFR <60 mL/min, FT1 resulted in 16.0% (39/244) and NF5 in 23.3% clinical failures (110/472), aOR: 0.61, 95% CI: 0.39–0.95). Conclusions: In eGFR ≥60 mL/min treatment with fosfomycin or trimethoprim for uncomplicated cystitis was associated with more clinical failure than treatment with nitrofurantoin, while in eGFR <60 mL/min nitrofurantoin was associated with more clinical failure than fosfomycin–trometamol. Renal function, if known, should be considered in the clinical decision-making for cystitis treatment

Desmopressine voor de behandeling van nycturie bij ouderen: ongewenst door hoog risico op bijwerkingen?

Desmopressine, een synthetische analoog van het antidiuretisch hormoon, wordt gebruikt ter behandeling van nachtelijke incontinentie bij kinderen en sinds enkele jaren ook in de behandeling van nycturie bij ouderen. Nycturie bij ouderen veroorzaakt slaapstoornissen en is geassocieerd met een hogere kans op vallen en een hogere mortaliteit. Desmopressine leidt bij ouderen tot een significante afname van de nycturie en daarmee tot een betere slaapkwaliteit. Hierdoor wordt het steeds meer voorgeschreven bij ouderen. Desmopressine veroorzaakt bij volwassenen in 15% een borderline hyponatriëmie (Na=130–135mmol/l) en in 5 % een ernstige hyponatriëmie. Predisponerende factoren hiervoor zijn een hogere dosis, leeftijd > 65jaar, een laag-normaal serum natrium, een hoog basaal 24-uurs urine volume, co-medicatie, zoals thiazidediuretica, tricyclische antidepressiva’s, specifieke serotonineheropnameremmers, chlorpromazine, carbamazepine, loperamide en NSAIDs (Non-Steroidal Anti-Inflammatory Drugs). Een hyponatriëmie kan, indien ernstig en snel ontstaan, klachten geven zoals hoofdpijn, misselijkheid, braken, duizeligheid en het kan in ernstige gevallen leiden tot somnolentie, bewustzijnsverlies en overlijden. Wij presenteren twee patiënten waarbij desmopressine-gerelateerde hyponatriemie aanleiding was voor ziekenhuisopname. Vanwege het hoge risico op hyponatriëmie bij ouderen na gebruik van desmopressine, moeten alternatieve behandelingsstrategieën voor nycturie eerst worden overwogen. Indien desmopressine toch wordt voorgeschreven, is nauwgezette controle van het serum natrium noodzakelijk

Prevention Of Xerophthalmia By Oral Massive Dose Vitamin A: (A Preliminary Report)

Untuk menilai efektivitas pemberian vitamin A dosis tinggi (200.000 IU vitamin A dan 40 IU vitamin E) secara masai dalam USAha pencegahan xerophthalmia, dilakukan penelitian terhadap seluruh anak umur 1-5 tahun di tujuh RK kotamadya Salatiga dan lima desa kabupaten Semarang, oleh suatu team ophthalmologi. Pada pemeriksaan awal ditemukan 132 penderita xerophthalmia diantara 2812 anak (4,7 persen). Kepada 2680 anak yang tidak menderita xerophthalmia sebagian diberi kapsul vitamin A dosis tinggi dan sebagian lain diberi kapsul placebo yang identik, secara "double-blind" diperiksa ulang sesudah enam bulan. Ternyata bahwa 7 diantara 1286 anak penerima vitamin A yang diperiksa (0,5 persen) menunjukkan tanda-tanda xerophthalmia. Sedang diantara 1183 anak penerima placebo yang diperiksa ternyata terdapat 43 penderita xerophthalmia (3,6 persen). Secara statistik bedanya amat bermakna. Tanda-tanda utama yang ditemukan adalah kombinasi dari buta-senja, xerosis conjunctiva, dan bercak Bitot. Kedua tanda yang terakhir ini terdapat pada 90 persen dari penderita, sedang buta-senja hanya 15 persen. Pada pemeriksaan ulang 132 anak penderita xerophthalmia yang telah diberi kapsul vitamin A dosis tinggi ternyata bahwa 91 persen dari yang diperiksa tidak lagi memperlihatkan tanda-tanda xerophthalmia. Jumlah anak yang tidak dapat diperiksa kembali jauh dibawah angka perkiraan. Sebagian besar karena telah pindah alamat, sebagian kecil meninggal. Antara golongan placebo dan vitamin, jumlah anak yang tidak dapat diperiksa kembali ini sama besar. Penelitian ini membuktikan bahwa kapsul vitamin A dosis tinggi efektip sekali untuk mencegah timbulnya xerophthalmia dan menyembuhkan gejala-gejala xerophthalmia ringan

Cost-effectiveness of nurse-led self-help for recurrent depression in the primary care setting: design of a pragmatic randomized trial

<p>Abstract</p> <p>Background</p> <p>Major Depressive Disorder is a leading cause of disability, tends to run a recurrent course and is associated with substantial economic costs due to increased healthcare utilization and productivity losses. Interventions aimed at the prevention of recurrences may reduce patients' suffering and costs. Besides antidepressants, several psychological treatments such as preventive cognitive therapy (PCT) are effective in the prevention of recurrences of depression. Yet, many patients find long-term use of antidepressants unattractive, do not want to engage in therapy sessions and in the primary care setting psychologists are often not available. Therefore, it is important to study whether PCT can be used in a nurse-led self-help format in primary care. This study sets out to test the hypothesis that usual care plus nurse-led self-help for recurrent depression in primary care is feasible, acceptable and cost-effective compared to usual care only.</p> <p>Design</p> <p>Patients are randomly assigned to ‘nurse-led self-help treatment plus usual care’ (134 participants) or ‘usual care’ (134 participants). Randomisation is stratified according to the number of previous episodes (2 or 3 previous episodes versus 4 or more). The primary clinical outcome is the cumulative recurrence rate of depression meeting DSM-IV criteria as assessed by the Structured-Clinical-Interview-for-DSM-IV- disorders at one year after completion of the intervention. Secondary clinical outcomes are quality of life, severity of depressive symptoms, co-morbid psychopathology and self-efficacy. As putative effect-moderators, demographic characteristics, number of previous episodes, type of treatment during previous episodes, age of onset, self-efficacy and symptoms of pain and fatigue are assessed. Cumulative recurrence rate ratios are obtained under a Poisson regression model. Number-needed-to-be-treated is calculated as the inverse of the risk-difference. The economic evaluation is conducted from a societal perspective, both as a cost-effectiveness analysis (costs per depression free survival year) and as a cost-utility analysis (costs per quality adjusted life-year).</p> <p>Discussion</p> <p>The purpose of this paper is to outline the rationale and design of a nurse-led, cognitive therapy based self-help aimed at preventing recurrence of depression in a primary care setting. Only few studies have focused on psychological self-help interventions aimed at the prevention of recurrences in primary care patients.</p> <p>Trial registration</p> <p>NTR3001 (<url>http://www.trialregister.nl</url>)</p

[Desmopressin for nocturia in the old: an inappropriate treatment due to the high risk of side-effects?].

Contains fulltext : 87379.pdf (publisher's version ) (Closed access)Desmopressin, a synthetic analog of the antidiuretic hormone, is used in the treatment of enuresis nocturna in children and increasingly also in adults. Nocturia in the elderly causes sleeping disorders and is associated with a higher risk of falling and increased mortality. Desmopressin leads to a significant decrement of nocturia and consequently, a better sleep quality and is for this reason increasingly prescribed in the old. Desmopressin causes borderline hyponatremia (130-135 mmol/l) in 15% and severe hyponatremia in 5% of all adult users. Factors that predispose to hyponatremia are a higher dose, age > 65 years, a low-normal serum sodium, a high 24-hour urine volume and co-medication (thiazide diuretics, tricyclic antidepressants, serotonin-reuptake-inhibitors, chlorpromazine, carbamazipine, loperamide, Non-Steroidal-Anti-Inflammatory-Drugs). Hyponatremia is associated with headache, nausea, vomiting, dizziness, and can cause somnolence, loss of consciousness and death. We present two cases where initiation of desmopressin led to hyponatremia, requiring hospitalization. In view of the high risk of desmopressin-associated hyponatremia in the older population, alternative treatment strategies for nocturia must be considered first. If desmopressin is prescribed, strict follow-up of serum sodium levels is necessary.1 december 201
