Occult hepatitis B among patients with chronic renal failure on hemodialysis from a capital city in northeast Brazil

Abstract Occult hepatitis B (OHB) is characterized by the presence of HBV‐DNA in the absence of HBsAg in the serum of patients. Hemodialysis patients are at high risk for hepatitis B virus and there are few data on the prevalence of OHB in this population, mainly in Brazil. Thus, the aim of this study was to determine the prevalence of OHB in patients undergoing hemodialysis. A cross‐sectional study was performed, including 301 patients on chronic hemodialysis at two dialysis centers in São Luís (Maranhão), northeast Brazil. Serological tests were performed for HBsAg, anti‐HBc, anti‐HBs, and anti‐HCV using enzyme immunoassays (ELISA); HBV‐DNA and HCV‐RNA were studied by real‐time PCR. The mean age was 49 ± 15 years, and 128 (42%) were female. Serological tests confirmed that all samples were HBsAg negative. Anti‐HBc was positive in 114 (38%) patients, anti‐HBc and anti‐HBs were simultaneously positive in 104 (35%), and anti‐HBc alone was positive in 10 (3%). Tests were negative for anti‐HBc and anti‐HBs in 55 patients (18%). Anti‐HBs was the only positive marker in 132 (44%) patients. Anti‐HCV was positive in 15 (5%) patients with HCV‐RNA present in 14 of them (93%). HBV‐DNA was positive in seven cases (2.3%). There was no association of HBV‐DNA with age, gender, time on dialysis, previous kidney transplant, or HBV serological pattern, but there was a positive correlation with the presence of anti...

Predicting survival function and identifying associated factors in patients with renal insufficiency in the metropolitan area of Maringá, Paraná State, Brazil. Cad Saude Publica. 2018 Feb 05;34(1):e00075517 Authors: Ramires TG, Nakamura LR, Righetto AJ, Ortega EMM, Cordeiro GM Abstract Renal insufficiency is a serious medical and public health problem worldwide. Recently, although many surveys have been developed to identify factors related to the lifetime of patients with renal insufficiency, controversial results from several studies suggest that researches should be conducted by regio...

Abstract Simultaneous liver, pancreas-duodenum, and kidney transplantation has been rarely reported in the literature. Here we present a new and more efficient en bloc technique that combines classic orthotopic liver and pancreas-duodenum transplantation and heterotopic kidney transplantation for a male patient aged 44 years who had hepatitis B related cirrhosis, renal failure, and insulin dependent diabetes mellitus (IDDM). A quadruple immunosuppressive regimen including induction with basiliximab and maintenance therapy with tacrolimus, mycophenolate mofetil, and steroids was used in the early stage post-transpl...

Abstract Chronic renal failure is a frequent complication in liver transplantation. Telbivudine, anti-hepatitis B virus (HBV) nucleoside, can improve renal function. It is interesting if using telbivudine for prophylaxis of HBV recurrence has additional value on renal function improvement. 120 liver transplant recipients with lamivudine prophylaxis for HBV recurrence were 1 : 1 randomized into lamivudine-continuous (n = 60) and telbivudine-replacement (n = 60) groups. Fifty-eight patients in lamivudine-continuous group and 54 in telbivudine-replacement group completed the study. In telbivudine-replac...

CONCLUSIONS SLKT in patients with hepatitis B had higher early-stage infection rate, but had a higher long-term survival rate compared with the LT group. Although the incidence of postoperative hepatitis B relapse in SLKT recipients was higher, timely and reasonable treatment can ensure long-term survival of patients. Worsening RIFLE stage of recipients can predict high mortality when only given LT. SLKT might be a better choice for RIFLE stage 2 or 3 patients than LT alone.

Abstract Transfusion-transmitted virus (TTV) is a single-stranded DNA virus that was identified in patients with post-transfusion hepatitis of non-A-to-G type. Patients with chronic renal failure on maintenance hemodialysis (HD) have a higher risk of viral infections, and the prevalence of TTV infection is common. The aim of our study was to detect TTV-DNA and its genotype in HD patients. A case-control study compromising of 63 patients on maintenance HD therapy at the Nephrology Center of Central Arar Hospital and 100 healthy individuals who were tested for TTVDNA and its genotype by semi nested-polymerase chain ...

Abstract We studied the dialysis practice-patterns with regard to various aspects of chronic kidney disease (CKD) stage 5D, like anemia, mineral bone disease, vaccination, hospitalization, hypertension and cost of therapy. Four hundred and sixty-four adult hemodialysis (HD) patients from various dialysis centers of Mumbai were included in the study. The mean age of the study patients was 47.2 years. Temporary dialysis catheters were the most common initial vascular access. Thirteen percent of prevalent HD patients were on temporary catheters; 33% of patients had history of failure of arterio-venous fistula. The mo...
