- Abdominal tuberculosis: an old disease surprising young doctors.Publication . Sousa, M; Batista, J; Pacheco, P; Nunes, VTuberculosis remains a worldwide public health concern. Atypical extrapulmonary presentations may delay the diagnosis and treatment. We present the case of an adult woman admitted to the emergency department with bowel obstruction. The putative intraoperative diagnostic hypothesis was ovarian cancer with peritoneal dissemination. Histopathological analysis showed a chronic granulomatous inflammatory disease with acid-fast bacilli. The patient was started on an alternative parenteral antituberculosis drug combination until oral feeding was available. Currently, 5 months after surgery, she is asymptomatic. Abdominal tuberculosis is the most frequent extrapulmonary site with a wide range of clinical presentations. Emergency laparotomy may be necessary in patients who present with acute abdomen. Bowel obstruction due to adhesions and strictures is not infrequent. However, tuberculous abdominal cocoon presentation as in our patient is rare. Treatment with parenteral alternative drug regimens for tuberculosis is mandatory until the oral route is available.
- Abordagem Diagnóstica e Terapêutica da Diabetes Mellitus no Doente com Infeção pelo Vírus da Imunodeficiência HumanaPublication . Gomes, F; Vasconcelos, P; Pacheco, PA terapêutica antirretroviral levou a uma redução significativa da morbi e mortalidade nos doentes infetados pelo vírus da imunodeficiência humana. No entanto, as complicações cardiometabólicas do tratamento e o envelhecimento desta população têm alargado a complexidade de cuidados para a gestão de comorbilidades cardiovasculares. O aumento da insulinorresistência e da prevalência da diabetes mellitus tipo 2 nestes doentes é já conhecida há alguns anos, sendo, deste modo, importante conhecer as particularidades do rastreio e da abordagem terapêutica desta doença metabólica. O presente trabalho tem como objetivo rever a abordagem diagnóstica e terapêutica da diabetes mellitus no doente com infeção pelo vírus da imunodeficiência humana, assim como as interações farmacológicas entre a terapêutica antirretroviral e os antidiabéticos, visto que a literatura é escassa neste tema, que consideramos ser útil na prática clínica.
- Artemether/Lumefantrine for the Treatment of P. malariae in a Patient on HemodialysisPublication . Patrocínio-Jesus, R; Cunha, J; Trigo, D; Flor-de-Lima, B; Pacheco, PThe combination of artemether/lumefantrine is indicated for the treatment of acute uncomplicated Plasmodium falciparum malaria. There have been no clinical trials to assess the efficacy of this medication in patients with renal impairment. While it is unlikely that artemether/lumefantrine would be removed during dialysis, clinical experience regarding drug use in this setting is limited. In this article, the authors report successful treatment of Plasmodium malariae malaria on a patient with end-stage kidney disease undergoing hemodialysis.

- Chronic hepatitis C treatment in HIV co-infection in Portugal: Results from a cohort OF 2133 patients presented by GEPCOI (Portuguese Coinfection Study Group)Publication . Miranda, AC; Mendez J, J; Serrão, R; Vale, F; Manata, MJ; Pinto, S; Gomes, A; Valente, C; Pacheco, P, et al.Direct-acting antiviral drugs (DAAs) have recently changed the paradigm of hepatitis C therapy, significantly improving treatment response rates, patient life expectancy and quality of life. In Portugal, sofosbuvir (SOF) and SOF/ledipasvir (SOF/LDV) were fully reimbursed by the National Health System since early 2015 and generalized use of interferon-free DAA based regimens became current practice. During 2016, the remaining DAAs were sequentially added and covered by the same health access policy. The Portuguese Study Group of Hepatitis and HIV Co-infection (GEPCOI) collected data from 15 clinical centres in Portugal, pertaining to the HCV treatment experience with DAA regimens. A cohort of 2133 patients was analysed, representing one of the largest DAA treated HCV/HIV co-infected individuals. The global sustained virologic response (SVR) achieved was 95% in this real-life cohort setting. Linear regression analysis showed significant differences in treatment response rates when using SOF plus ribavirin (RBV) combination in genotype 2 or 3 infected individuals (P < .002) and in those with liver cirrhosis (P < .002). These findings corroborate that early treatment is mandatory in HIV/HCV co-infected patients, as response rates may be negatively influenced by higher fibrosis stages and suboptimal DAA regimens. The current national Portuguese health policy should continue to promote wider treatment access and individualized therapy strategies, aiming at the elimination of HCV infection in this high-risk co-infected population
- Clinical experience in invasive fungal infectionsPublication . Pacheco, P; Ventura, A; Branco, T; Gonçalves, L; Carvalho, CLung infections caused by invasive filamentous fungi are very rare conditions in AIDS, but must be considered in patients with profound immune suppression especially in the presence of additional risk factors, such as hematologic malignancies, corticosteroid therapy, neutropenia, and chemotherapy. The authors report a case of dual lung infection caused by Aspergillus and Mucor, which occurred in a 34-year-old AIDS patient who was treated with chemotherapy for oral plasmablastic lymphoma. The case presented clinically with low grade fever and pulmonary cavitation, which suggested tuberculosis. After extensive investigation the diagnosis of mucormycosis was established and the patient was treated sequentially with liposomal amphotericin B and posaconazole. Despite a reduction in the size of the pulmonary cavitation, improvement of the lung interstitial infiltrates and clinical recovery, the patient was submitted to cardiothoracic surgery given the aggressive behavior of this invasive fungus. Histology of the surgical specimen showed numerous hyphae with a morphologic pattern compatible with Aspergillus as well as hyphae that were suggestive of Mucor.
- Clinical management of ageing people living with HIV in Europe: the view of the care providersPublication . Boffito, M; Ryom, L; Spinner, C; Martinez, E; Behrens, G; Rockstroh, J; Hohenauer, J; Lacombe, K; Psichogyiou, M; Voith, N; Mallon, P; Branco, T, et al.BACKGROUND: Although guidelines for the management of HIV infection include recommendations for aging people living with HIV (PLWH), clinical practice of European HIV care providers may vary. METHOD: We performed a study using a 3-phase Delphi methodology by involving a panel of clinicians with expertise in HIV infection clinical management. The main aim of the study was to assess the care provider prospective on how HIV clinical care should be delivered to ageing PLWH. The first phase involved ten clinicians to identify HIV comorbidities of interest. The second and third phases recruited clinicians virtually via a web-based questionnaire that included 137 questions focussed on 11 comorbidities (e.g. cardiovascular disease, pulmonary disease, etc.). RESULTS: Results were analysed thematically and consensus (or not) among European physicians reported. Ninety-seven and 85 responses were collected in phase 2 and 3, respectively. High levels of agreement were found among clinical care providers across Europe and with the European AIDS Conference Society guidelines regarding key items of clinical management of comorbidities in ageing PLWH. CONCLUSION: However, we identified some important gaps, such as the lack of standardisation or implementation of the assessment of frailty or menopause, which are emerging as important factors to optimise ageing PLWH clinical care. Further studies are warranted to confirm whether intensified screening translates into HIV morbidity advances.

- Differences in nevirapine biotransformation as a factor for its sex-dependent dimorphic profile of adverse drug reactions.Publication . Marinho, A; Rodrigues, P; Caixas, U; Antunes, A; Branco, T; Hargivan, S; Marques, M; Monteiro, E; Pereira, SOBJECTIVES: Nevirapine is widely used for the treatment of HIV-1 infection; however, its chronic use has been associated with severe liver and skin toxicity. Women are at increased risk for these toxic events, but the reasons for the sex-related differences are unclear. Disparities in the biotransformation of nevirapine and the generation of toxic metabolites between men and women might be the underlying cause. The present work aimed to explore sex differences in nevirapine biotransformation as a potential factor in nevirapine-induced toxicity. METHODS: All included subjects were adults who had been receiving 400 mg of nevirapine once daily for at least 1 month. Blood samples were collected and the levels of nevirapine and its phase I metabolites were quantified by HPLC. Anthropometric and clinical data, and nevirapine metabolite profiles, were assessed for sex-related differences. RESULTS: A total of 52 patients were included (63% were men). Body weight was lower in women (P = 0.028) and female sex was associated with higher alkaline phosphatase (P = 0.036) and lactate dehydrogenase (P = 0.037) levels. The plasma concentrations of nevirapine (P = 0.030) and the metabolite 3-hydroxy-nevirapine (P = 0.035), as well as the proportions of the metabolites 12-hydroxy-nevirapine (P = 0.037) and 3-hydroxy-nevirapine (P = 0.001), were higher in women, when adjusted for body weight. CONCLUSIONS: There was a sex-dependent variation in nevirapine biotransformation, particularly in the generation of the 12-hydroxy-nevirapine and 3-hydroxy-nevirapine metabolites. These data are consistent with the sex-dependent formation of toxic reactive metabolites, which may contribute to the sex-dependent dimorphic profile of nevirapine toxicity.
