RESUMEN
Sweet Syndrome belongs to a group of diseases known as neutrophilic dermatoses. An uncommon variant named Histiocytoid Sweet Syndrome (HSS) can be associated with a variety of conditions, including cancer, infections, drug toxicity and others. Here we present an instance of HSS in an HIV-positive patient in an infectious disease setting.

BACKGROUND: Bone alterations have been observed in the course of HIV infection, characterized by a marked decrease in bone mineral density (BMD) and an increase in the frequency of fractures as a result of fragility. We aim to evaluate early changes in bone metabolic profile and the possible association with tenofovir and other nucleoside and nucleotide reverse transcriptase inhibitors (NRTIs) in treatment-naïve HIV patients. METHODS: We conducted a prospective study in naïve HIV-infected adults (under 50 years), separated into three groups according to NRTI therapy: tenofovir disoproxil fumarate (TDF); tenofovir alafenamide (TAF) and abacavir (ABC). BMD and epidemiological, immunological and metabolic bone parameters were evaluated. Bone markers were analyzed in plasma at baseline, 12 and 48 weeks after initiating treatment. RESULTS: Average age of patients was 34.8 years (± 9.6). 92.4% of them with CD4 count > 200 cel/µL. At week 12 after starting treatment, both TDF [increase in PN1P (31.7%, p = 0.004), TRAP (11.1%, p = 0.003), OPN (19.3%, p = 0.045) and OC (38.6%, p = 0.001); decrease in OPG (-23.4%, p = 0.003)] and TAF [increase in 42.6% for CTX (p = 0.011), 27.3% for OC (p = 0.001) and 21% for TRAP (p = 0.008); decrease in OPG (-28.8%, p = 0.049)] presented a deep resorption profile compared to ABC, these differences in bone molecular markers, a tendency to equalize at week 48, where no significant differences were observed. Patients treated with TDF showed the greatest decrease in Z-score in both lumbar spine (LS) and femoral neck (FN) at week 48 without statistically significant differences. CONCLUSION: Treatment-naïve HIV patients have a high prevalence of low bone density. Treatment with TDF is associated with greater bone deterioration at 12 and 48 weeks. TAF seems to present similar early bone deterioration at 12 weeks which disappears at 48 weeks.

BACKGROUND: Spain is the European country with the highest number of Trypanosoma cruzi infected patients. Due to the cardiac complications that these patients can develop, it is of paramount importance to evaluate the value of the different heart diagnostic tools. METHOD: In this observational study, we describe the main characteristics and data from electrocardiogram, chest X-ray, echocardiogram and cardiac magnetic resonance imaging (MRI) of 141 patients with Chagas' disease attended in a tertiary university hospital in Madrid from 2009 to 2018. RESULTS: A total of 50 patients (35.4%) had at least one abnormal cardiac test: 34.2% altered electrocardiogram (40/117), 24.5% altered echocardiogram (27/110) and 9.2% abnormal cardiac MRI (13/41). Of those 13 with a pathological MRI, 53.8% had normal results for any other test. The most frequent alterations observed were hypokinesia with decreased LVEF (left ventricular ejection fraction), dilatation of cavities and cardiac fibrosis. Two thirds of patients with abnormal cardiac test were asymptomatic. Altered echocardiogram was found in 43.8% of patients ≥50 years compared to 16.6% under 50 years (p = 0.003). CONCLUSIONS: A transthoracic echocardiogram and a MRI of the heart added a 23.8% increment in diagnosing cardiac pathological findings.
