Calcitonin levels in autoimmune atrophic gastritis-related hypergastrinemia.

PURPOSE: Calcitonin (Ct) is currently the most sensitive biochemical marker of C-cell disease (medullary thyroid cancer [MTC] and C-cell hyperplasia), but its specificity is relatively low. Our aim was to examine whether autoimmune atrophic gastritis (AAG) and chronic hypergastrinemia, with or without chronic autoimmune thyroiditis (AT), are conditions associated with increased Ct levels. METHODS: Three groups of patients were consecutively enrolled in this  multicentric study: group A consisted of patients with histologically-proven AAG (n = 13; 2 males, 11 females); group B fulfilled the criteria for group A but also had AT (n = 92; 15 males, 77 females); and group C included patients with AT and without AAG (n = 37; 6 males, 31 females). RESULTS: Median Ct levels did not differ between the three groups. Ct levels were undetectable in: 8/13 cases (61.5%) in group A, 70/92 (76.1%) in group B, and 27/37 (73.0%) in group C. They were detectable but ≤ 10 ng/L in 4/13 (30.8%), 20/92 (21.7%) and 7/37 (18.9%) cases, respectively; and they were > 10 ng/L in 1/13 (7.7%), 2/92 (2.2%) and 3/37 (8.1%) cases, respectively (P = 0.5). Only three patients had high Ct levels (> 10 ng/L) and high gastrin levels and had an MTC. There was no correlation between Ct and gastrin levels (P = 0.353, r = 0.0785). CONCLUSIONS: High gastrin levels in patients with AAG do not explain any hypercalcitoninemia, regardless of whether patients have AT or not. This makes it mandatory to complete the diagnostic process to rule out MTC in patients with high Ct levels and AAG.

Left spermatic vein reflux after varicocele repair predicts pregnancies and live births in subfertile couples.

PURPOSE: Varicocele repair (VR) is proposed to improve fertility in subfertile couples with a poor semen quality. We explored whether the disappearance of a left continuous spermatic venous reflux (SVR) at scrotal colour-Doppler ultrasound (CDUS), an objective evidence for a VR, is predictive for improved fertility outcome in subfertile couples. METHODS: VR was performed by left internal spermatic vein sclero-embolisation in 88 males seeking a consultation for subfertility. Semen analysis and scrotal CDUS were evaluated before and 6 months after VR. Serum levels of FSH and total testosterone (TT) were obtained at baseline. Telephone interview was used to obtain information about fertility outcome. Significant predictors of pregnancy and live births, selected by univariate analyses, were included into multiple logistic regression models to assess independent associations. RESULTS: At the adjusted model, independent significant predictors of pregnancy after VR were a disappeared SVR at CDUS (OR = 5.5, 97.5% CI 2.01-15.4; p = 0.0009) and an improved sperm total motile count (TMC) (OR = 5.5, 97.5% CI 1.4-27.9; p = 0.02). Even live births were independently associated with both disappeared left SVR at CDUS (OR = 4.3, 97.5% CI = 1.6-11.8; p = 0.003) and improved TMC after VR (OR = 4.8, 97.5% CI 1.3-24.2; p = 0.02). CONCLUSION: The still controversial effect of varicocele repair on fertility in subfertile couples may reside on the undefined objective methods to document a successful VR and its effect on couple fertility. The disappearance of a continuous left SVR at CDUS after VR was the objective best predictor for subsequent improved fertility in subfertile couples.

Bone turnover markers, BMD and TBS after short-term, high-dose glucocorticoid therapy in patients with Graves' orbitopathy: a small prospective pilot study.

PURPOSE: Chronic GC administration has numerous side effects, but little is known about the side effects of their short-term use (< 3 months)-particularly, when high doses are involved, as in the treatment of Graves' orbitopathy (GO). We investigated the effects of short-term, high-dose GC on bone turnover markers, bone mineral density (BMD), and trabecular bone scores (TBS). METHODS: Eleven patients (10 females and 1 male; median age 56 years) with active GO who were candidates for treatment with intravenous (iv) methylprednisone were consecutively enrolled. All patients were pretreated with a loading dose of 300,000 units of cholecalciferol, then given a median cumulative dose of 4.5 g (range 1.5-5.25 g) iv methylprednisone. Biochemical parameters of bone metabolism (25OHD3, PTH, P1NP, CTX and bALP) were measured at the baseline, and then 1 week and 1, 3, 6 and 12 months. BMD and TBS were obtained by X-ray absorptiometry (DXA) at the baseline and at 6 and 12 months. On DXA image, morphometric vertebral fracture assessment (VFA) was done. RESULTS: There were no significant changes in PTH, bALP or P1NP. A significant drop in CTX was seen at 1 month (down Δ49.31% from the baseline, p = 0.02), with a return to the baseline at the 3-month measurement. There was a moderate (not significant), but persistent reduction in P1NP. No changes in BMD or TBS came to light. No vertebral fractures were documented. CONCLUSIONS: Short-term, high-dose GC treatment caused a rapid, transient suppression of bone resorption, with no effects on BMD or bone micro-architecture (TBS).

Determination of spermatic vein reflux after varicocele repair helps to define the efficacy of treatment in improving sperm parameters of subfertile men.

PURPOSE: A continuous spermatic venous reflux (SVR) at colour Doppler ultrasound (CDU) is an evidence for varicocele, a frequent correlate for male subfertility. We explored whether SVR after left varicocele repair is predictive for changes in semen quality in subfertile men. METHODS: Blood hormones (FSH, LH, and total testosterone) and scrotal CDU were obtained in subfertile patients with left grade II or grade III varicocele on physical evaluation and a poor sperm quality. Semen analysis and CDU were re-evaluated 6 months after a retrograde internal spermatic vein scleroembolisation. RESULTS: The retrospective study included 100 men with a baseline SVR >3 cm/s; 60 men showed a disappearance (group 1) and 40 men (group 2) showed a reduced SVR after varicocele repair. Total motile sperm count (TMC) was markedly increased after treatment (p < 0.0001; F = 35.79) and the increase was more relevant in group 1 compared to group 2 (p = 0.04; F = 4.20). TMC and left SVR values after varicocele repair were negatively correlated (R = -0.218; p = 0.035). Multivariate analysis showed that adjusted SVR after repair negatively predicted TMC change (TMC after repair minus baseline TMC) (ß = -2.56; p = 0.022). Disappearance of a continuous left SVR at CDU after varicocele repair was associated to a better improvement of semen parameters in subfertile men. CONCLUSION: Recording of a continuous left spermatic vein reflux is an objective method to assess a successful varicocele repair aimed to improve sperm parameters in subfertile men.

Embolization of left spermatic vein in non-obstructive azoospermic men with varicocele: role of FSH to predict the appearance of ejaculated spermatozoa after treatment.

PURPOSE: Varicocele repair in non-obstructive azoospermia (NOA) was occasionally associated to ejaculated spermatozoa independently from clinical and laboratory measures. We performed a prospective study in infertile men affected by NOA and left side varicocele to find whether or not the appearance of ejaculated spermatozoa after varicocele repair is predicted by baseline measures. METHODS: Patients with NOA and grade II, or grade III left side varicocele were submitted to hormone analysis and to scrotal color Doppler ultrasound (CDU). Azoospermia was confirmed in 23 patients aged 25-47 years who were than submitted to varicocele repair through a retrograde internal spermatic vein embolization. Patients were re-evaluated after 6 months. RESULTS: Six months after varicocele repair 12 patients (52.2 %) were still azoospermic (Group 1) while 11 patients (47.8 %) reported ejaculated spermatozoa (Group 2) [sperm count: 1.3 × 10(6)/mL; 0.5 × 10(6)/mL-1.6 × 10(6)/mL (median 25th-75th centiles)]. Serum baseline FSH was lower in Group 2 compared to Group 1 (p = 0.012), while no differences between groups were revealed for all other clinical and laboratory parameters. ROC analysis indicated that baseline FSH level predicted the appearance of ejaculated spermatozoa after treatment [AUC = 0.811; 95 % Confidence Interval (CI) 0.6-0.9; p = 0.0029]. A cut-off level of FSH <10.06 mIU/mL identified 82.0 % of cases with ejaculated spermatozoa with a specificity of 81.8 % and a sensitivity of 83.3 %. CONCLUSION: Selected patients with NOA may show ejaculated spermatozoa after a non-invasive repair of a left side varicocele, therefore avoiding testicular sperm extraction. Baseline serum FSH was a valuable predictor for ejaculated spermatozoa after treatment.

Hip viscosupplementation under ultra-sound guidance riduces NSAID consumption in symptomatic hip osteoarthritis patients in a long follow-up. Data from Italian registry.

INTRODUCTION: Non-steroidal anti-inflammatory drugs (NSAIDs) consumption is strictly related to a high gastrointestinal and cardiovascular mortality and morbidity rate. Osteoarthritis Research Society International (OARSI) recommendations in patients with symptomatic hip or knee OA stated that NSAIDs should be used at the lowest effective dose but their long-term use should be avoided if possible. OARSI guidelines for the treatment of the hip OA include the use of viscosupplementation, which aims to restore physiological and rheological features of the synovial fluid. OBJECTIVE: Aim of this multicentric, open and retrospective study is to investigate if NSAID consumption may be reduced by the use of ultrasound-guided intra-articular injection of several hyaluronic acid (HA) products in hip joint administered in patients affected by symptomatic hip OA. MATERIALS AND METHODS: Patients affected by mono or bilateral symptomatic hip OA according to American Rheumatology Association (ARA) criteria, radiological OA graded II-IV (Kellgren and Lawrence) entered the study and were administered with ultrasound-guided intra-articular injection of hyaluronic acid products. As a primary endpoint, consumption of NSAIDs was evaluated by recording the number of days a month (range 0-30) the patient had used NSAID during the previous month, reported at each visit during the 24 months follow-up period. Secondary endpoints included further analysis for subgroups of patients categorized for Lequesne index score, Kellgren-Lawrence score, pain visual analogue scale (VAS) score, ultrasound pattern, age, hyaluronic acid used. RESULTS: 2343 patients entered the study. Regarding primary endpoint, the consumption of NSAIDs was reduced of 48.2% at the third month when compared with baseline values. This sparing effect increased at 12th and 24th month with a reduction respectively of 50% and 61% in comparison to baseline values. These differences were statistically significant. CONCLUSIONS: These data point out that intraarticular hyaluronan preparations provide OA pain relief and reduce NSAIDs consumption in a large cohort of patients for a long period of follow-up. Multiple courses of viscosupplementation (vs) are required to maintain low dose of NSAID consumption over time. NSAIDs consumption is strictly related to an high gastrointestinal and cardiovascular mortality and morbidity rate, instead HA intra-articular treatment is well tolerated and is associated with a low incidence of adverse effects. For these reasons further studies evaluating cost-effectiveness and cost-utility of VS in the management of hip OA are required.
