SUMMARY OBJECTIVE The recent development of direct-acting antiviral agents (DAAs) has dramatically changed the treatment of chronic hepatitis C, and interferon-based regimes have become a poor treatment choice in clinical practice. Today DAAs offer shorter, well-tolerated, highly effective curative therapies. This study aimed to evaluate the effectiveness and safety of DAAs in patients with end-stage renal disease and HCV genotype 1 infection in real clinical practice. METHODS Thirty-six patients who attended our clinic, were diagnosed with chronic hepatitis C (CHC), undergoing hemodialysis, and fulfilled the criteria of age >18 years, genotype 1 infection, with a detectable HCV RNA level were considered for the study. Patients with GT1a infection received OBV/PTV/r plus DSV plus RBV for 12 weeks; GT1b infected patients received this regimen without RBV for 12 weeks. RESULTS The study was conducted on 33 patients. The mean age was 52.30 ±13.77 years, and 70 % of them were male. By the fourth week of treatment, HCV RNA levels decreased below 15 IU/ml in all patients. Sustained virologic response (SVR) 12 rate was 100%. Nine patients had side effects during treatment. Of the patients with side effects, 89.9% were in group 1a and 11.1% in group 1b. CONCLUSION In this study, treatment with OBV/PTV/r and DSV with or without RBV resulted in high rates of sustained virologic response in HCV GT1-infected patients with end-stage renal disease (ESRD). SVR was achieved in all patients with few side effects.
RESUMO O recente desenvolvimento de agentes antivirais de ação direta (DAAs) mudou drasticamente o tratamento da hepatite C crônica, e os regimes livres de interferon tornaram-se pobres escolhas para tratamento na prática clínica. Hoje os DAAs oferecem terapias curativas mais curtas, bem toleradas e altamente eficazes. O objetivo deste estudo foi avaliar a eficácia e segurança dos DAAs em pacientes com doença renal em estágio terminal e infecção pelo genótipo 1 do HCV na prática clínica real. MÉTODOS Trinta e seis pacientes, que se inscreveram em nossa clínica com diagnóstico de hepatite C crônica (CHC), inclusive no programa de hemodiálise, e preencheram os critérios de idade >18 anos, foram considerados para infecção pelo genótipo 1 com nível detectável de RNA do HCV. Os pacientes com infecção por GT1a receberam OBV/PTV/r mais DSV mais RBV por 12 semanas. Os pacientes infectados com GT1b receberam este regime sem RBV por 12 semanas. RESULTADOS O estudo foi realizado em 33 pacientes. A idade média foi de 52,30±13,77 anos e 70% deles eram do sexo masculino. Na semana 4 do tratamento, os níveis de ARN do VHC diminuíram para menos de 15 UI/ml em todos os pacientes. A taxa de resposta virológica sustentada (RVS) 12 foi de 100%. Nove pacientes apresentaram efeitos colaterais durante o tratamento. Dos pacientes com efeitos colaterais, 89,9% estavam no grupo 1a e 11,1% no grupo 1b. CONCLUSÃO Neste estudo, o tratamento com OBV/PTV/r e DSV com ou sem RBV resultou em altas taxas de resposta virológica sustentada em pacientes infectados pelo VGC GT1 com doença renal em estágio final (ESRD). A RVS foi alcançada em todos os pacientes com poucos efeitos colaterais.

Even in the era of novel targeted agents, switching to a second-line nonsteroidal antiandrogen (NSAA) is still widely used in treating metastatic castration-resistant prostate cancer (mCRPC), especially in undeveloped countries. However, whether prior treatment with a second-line NSAA would impact the efficacy of abiraterone acetate (Abi) remains uncertain. In the current study, 87 mCRPC patients treated with Abi were analyzed. Among them, 21 were treated with a second-line NSAA (from bicalutamide to flutamide) before receiving abiraterone, while the remaining 66 received Abi directly. Therapeutic efficacy of Abi was compared between those with and without prior second-line NSAA using Kaplan-Meier curves, log-rank test, and Cox regression models. The therapeutic efficacy of Abi was similar between those with or without the prior switching treatment of flutamide, in terms of either prostate-specific antigen progression-free survival (PSA-PFS, 5.5 vs 5.6 months, P = 0.967), radiographic progression-free survival (rPFS, 12.8 vs 13.4 months, P = 0.508), overall survival (OS, not reached vs 30.6 months, P = 0.606), or PSA-response rate (71.4% [15/21] vs 60.6% [40/66], P = 0.370). This is the first time that the impact of prior switching of treatment to a second-line NSAA on the efficacy of Abi in mCRPC patients has been addressed. Our data support that, use of prior sequential bicalutamide and flutamide does not seem to preclude response to abiraterone, although larger cohort studies and, ideally, a randomized controlled trial are needed. These findings will facilitate doctors' decision-making in the treatment of mCRPC patients, especially for those with previous experience of switching NSAA second-line treatments in the clinic.

ABSTRACT Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor originating from parafollicular C cells of the thyroid and associated with mutations in the proto-oncogene REarranged during Transfection (RET). The prognosis of MTC depends on clinical stage, with a 95.6% 10-year survival rate among patients with localized disease and 40% among patients with advanced disease. Standard chemotherapy and radiotherapy have no significant impact on the overall survival of these patients and two tyrosine kinase receptor inhibitors (TKIs), vandetanib and cabozantinib, have been recently approved for the systemic treatment of locally advanced or metastatic MTC. However, since patients with MTC and residual or recurrent disease may have an indolent course with no need for systemic treatment, and since these drugs are highly toxic, it is extremely important to select the patients who will receive these drugs in a correct manner. It is also essential to carefully monitor patients using TKI regarding possible adverse effects, which should be properly managed when occurring.

In this article, we will try to address the following aspects: which factors are responsible of the introduction of new candidates for hormone therapy in prostate cancer, who are actually candidates for hormone therapy, classifying them on the basis of the stage of the disease, and which treatment modalities can be proposed for each candidate. Since the introduction of hormone therapy for the treatment of prostate cancer, there has been a debate about the optimal timing of hormone therapy. A modification in the timing of hormone therapy produced new candidates for hormone manipulation. In particular, the use of hormone treatment for younger patients, longer periods and early prostate cancer, absolutely requires a whole re-evaluation of which therapy is indicated and it may produce new problems such as higher risk of over-treatment, need of a better evaluation of quality of life in younger patients and the research for better tolerated therapies. Therapies that resist for longer periods without the production of a hormone-refractory disease are also required.

A total of 62 leprosy patients, 47 lepromatous type, 9 tuberculoid, 5 borderline group and 1 indeterminate group, have been treated with a synthesized thiocarbanilide L-4, and the effectiveness of L-4 administration in the treatment of leprosy is evaluated on the basis of clinical and bacteriological improvements. The results are summarized and conc1uded as follows; 1. L-4, contained in gelatin capsule, can be safely administered orally to the patients through slow induction, from initial dosages of 50 mg to 100 mg dai1y to the therapeutic maintenance levels of 200 mg to 300 mg daily, for a period of time. 2. L-4 administration has brought apparent and remarkable improvement in clinical symptoms of the patients after a relatively short period of medication compared with that of DDS administration. 3. Changes of SFG values caused by L-4 administration were much speedier than, (or, at least, equivalent to) the effect caused by DDS. The changes of SFG values, in general, synchronized fairly well with clinical improvement of the patients. 4. Lepromatous cases with leprosy reaction or sulfone allergy responded well to L-4 medication with remarkable clinical improvement, and prolonged administration of L-4 did not provoke such a precipitating action to leprosy reaction as did DDS.
