[Side effects of antiretroviral therapy. Fisiopathology, clinical manifestations and treatment].

The suppression of plasma viral loads in HIV infected patients to less than the limit of quantification of the most sensitive commercially available assays and the coincident improvement in CD4 T cell counts is associated with a decrease in the risk of new opportunistic infections in this patients. The descent at the morbibility and mortality is specialy important since the introduction in 1996 the hard activity antirretroviral therapy (HAART). However, prolonged treatment with combination regimens can be difficult to sustain because of problems with adherence and toxic effects. All antiretroviral drugs can have both short-term and long-term adverse events. The risk of specific side effects varies acording to specific drug, drug class and even, individual susceptibility. A better understanding of the adverse effects of antiretroviral agents is of interest to try to optimize therapy in HIV infected patients.

[Treatment of chronic hepatitis C virus infection in human immunodeficiency virus (HIV) infected patients].

Treatment of chronic hepatitis C Virus (HCV) infection in human immunodeficiency virus (HIV) infected patients has become a topic of great importance, since the complications of chronic hepatitis are the first one cause of mortality among HIV patients. The aim of this study is to review the biological and epidemiological data in HIV-HCV coinfection, to establish treatment guidelines taking in consideration drugs' adverse effects and interactions, and to report the results of the main studies carried out. The treatment currently accepted includes pegylate interferon andribavirin, which have improved prior treatments, but the response rate depends on HCV genotype.

[Reversible dementias, do they exist?].

Due to the increase of the life expectancy the prevalence of the patients with dementia in the services of Internal Medicine is very high (30% in the patients with more of 80 years old). The incidence of the potentially reversible dementias is very different in the publications consulted (10-30%). The objective of these study is to know the real incidence of these dementias and which is the best diagnostic protocol to optimize the resources. The conclusions obtained in the bibliographical review it is that the effect of this type of dementias is minor that the mentioned (1.5-3%).

[Tongue tuberculosis as the first expression of the lung process].

Nowadays tuberculosis incidence seems to increase again after past decades fall. This event has been worsen because of the growth of resistances, basically due to patient's failure to comply with scheduled specific therapeutics. Anyway the decrease of tuberculosis leads initially to lowering of extrapulmonary forms, being the mouth cavity one of the most infrequent seat, so that location can be omitted at first glance diagnosis. We report one tongue tuberculosis case, which was the first expression of a lung tuberculosis, and discuss other manifestations within oral cavity and also the problems of some cases, as well as the best treatment.

[Iron metabolism in patient infected by human immunodeficiency virus type 1].

BACKGROUND: The aim of this work was to assess the major iron metabolism values in patients infected by human immunodeficiency virus (HIV), and to evaluate the correlation between these data and the immunological status of the patients as expressed by CD4 lymphocyte count. PATIENTS AND METHODS: Seventy-one patients infected by HIV (51 men and 20 women) with mean age of 29 years, plus a control group of 32 healthy subjects were studied. Haemoglobin, haematocrit, mean corpuscular volume, mean corpuscular haemoglobin, ferritin, transferrin, serum iron, total iron binding capacity and transferrin saturation index were studied in all of them. Erythrocyte sedimentation rate (ESR) and ALT were also determined in order to estimate the ferritin/ALT quotient. RESULTS: Mean haemoglobin concentration in the HIV-infected patients (133 +/- 22 g/L) was significantly lower (p < 0.05) than that of the control group (147 +/- 16 g/L), its decrease correlating in accordance with the CD4-cell count. Serum iron values in HIV infected patients (82 +/- 40 micrograms/L) are significantly lower (p < 0.02) than those of the control subjects (115 +/- 56 micrograms/ dL), decreasing in parallel with the number of CD4 lymphocytes. Serum ferritin of the HIV patients (259 +/- 250 ng/mL) is significantly higher that that of the normal group (95 +/- 73 ng/ mL), increasing with the decrease of CD4 cells. Significant correlation was found between ferritin and CD4 cells (r = 0.46, p < 0.0003) and positive correlation between ferritin and ESR (r = 0.70, p < 0.001) were found. CONCLUSIONS: As HIV infection advances, progressive anaemia is established. The study of iron metabolism in these patients shows a pattern similar to that of the anaemia of chronic diseases, with even higher serum ferritin. These changes might be due to iron sequestration in phagocytic cells induced by release of cytokines.

[Eosinophilic gastroenteritis and pulmonary thromboembolism. A chance association?].

We present the case of a patient whose clinical signs were abdominal pain, diarrhea and fever, in which the diagnosis of eosinophilic gastroenteritis (EEG) was established and during whose evolution he underwent a pulmonary thromboembolism (PTE). We comment the characteristics of the EEG, a rare entity sometimes included in the so-called idiopathic hypereosinophilic syndrome (IHS) and the potential relationship between PTE and hypercoagulability in the context of eosinophilia.
