The diagnosis of elderly-onset IgA vasculitis (IgAV) and its prognosis can be difficult to ascertain because of its rarity and the frequent presence of comorbidities. Furthermore, the treatment of elderly-onset IgAV remains controversial. We report a case of IgAV in an 87-year-old patient. Renal involvement was detected early during the IgAV follow-up. He was treated with low-dose corticosteroid and azathioprine, which led to a complete remission without any adverse effects. This suggests that precise intervention with early diagnosis and careful renal follow-up may prevent renal failure and that low-dose steroids with azathioprine can be an effective treatment for elderly-onset IgAV with nephritis.
Calcium channel blockers (CCBs) can prevent cardiovascular events in patients with coronary artery disease (CAD). This study looked retrospectively at the prognosis of CAD in hypertensive patients with CAD who had undergone a coronary angiograph, had been given a CCB (benidipine [n = 66], amlodipine [n = 45], or long-acting nifedipine [n = 31]) on hospital discharge and were then followed up for a mean +/- SD of 5.2 +/- 2.9 years. Systolic/diastolic blood pressure for all 142 patients decreased significantly from a mean +/- SD of 137 +/- 20/74 +/- 15 mmHg to 129 +/- 20/71 +/- 12 mmHg. Major adverse cardiovascular events (MACE) occurred in 15 patients. Chronic kidney disease (CKD) was a significant risk factor for MACE (hazard ratio 2.35, 95% confidence intervals 1.45, 3.80). Benidipine was superior to nifedipine in preventing MACE in patients both with and without CKD. In conclusion, benidipine and amlodipine reduced the frequency of MACE in hypertensive patients with CAD, particularly in those with complicating CKD.
Since the effect of the submaximal aerobic exercise on bone had been controversial, the aim of this study was to elucidate the effect of the bench step (BS), that seemed to deliver higher mechanical load on bone than any other aerobic exercises, on the total bone mineral content (BMC) and the bone metabolism of menopausal women. Sixteen menopausal women (65 ± 9 years old) as the exercise group (ExG) and 28 pre-menopausal women (43 ± 3 years old) as the control group (CG) were studied. ExG carried out BS training with the exercise intensity at lactate threshold (LT) for 21 weeks. In ExG, BMC was measured by dual energy X-ray absorptiometry (DXA) at one year before the intervention (A year before), preintervention (Pre) and post-intervention (Post). Serum osteocalcin (OC) as the marker of bone formation and serum type I collagen cross-linked N-telopeptide (NTx) as the marker of bone absorption at Pre, 11th week of the intervention and Post. In CG, BMC was measured annually without the intervention. In ExG, OC was not changed, but NTx was significantly decreased by intervention (p<0.05). The decreased amount of annual change in BMC between a year before and Pre (T1) was significantly higher compared to that between Pre and Post (T2) (p<0.01) and CG (p<0.001). There was no significant difference between T2 and CG. In conclusion, BS with LT could prevent decreasing BMC in menopausal women, and maintain the same level of BMC in pre-menopausal women by suppressing the bone absorption.
Hepatitis E, which is caused by hepatitis E virus (HEV), is a public health concern in Japan, where the zoonotic food-borne transmission of HEV from domestic pigs and wild boars plays an important role. A 44-year-old Japanese man with autochthonous sporadic acute hepatitis E was admitted with general fatigue and moderate liver dysfunction. In the present study, two distinct HEV strains were recovered from the patient, who had consumed the raw or undercooked pig liver and intestine two or three times per week for 3 months before the disease onset. The recovered HEV strains were segregated into two clusters within subgenotype 3b, the open reading frame (ORF)1 and ORF2 sequences of which each showed ~10% difference, indicating HEV mixed infection. Because most notified patients with clinical HEV infection in Japan are diagnosed based on the detection of IgA-class HEV antibodies and because serum samples from only a limited number of HEV-infected patients are subjected to HEV RNA detection and nucleotide sequencing, it is very likely that patients with HEV mixed infection remain largely overlooked. The identification of sources of autochthonous HEV infection remains an important goal. Continued efforts to trace the sources of acute or chronic autochthonous HEV infection are warranted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
