Histoplasmosis diseminada y síndrome hemofagocítico en pacientes VIH: serie de casos en un hospital peruano / Disseminated histoplasmosis and haemophagocytic syndrome in HIV patients: a case series in a Peruvian hospital

ANTECEDENTES: La histoplasmosis diseminada (HD) es una infección fúngica oportunista en pacientes con infección por VIH gravemente inmunocomprometidos. El síndrome hemofagocítico (SHF), que puede presentarse en estos pacientes coinfectados cuando la respuesta inmunitaria está significativamente alterada, suele estar asociado a una elevada mortalidad. OBJETIVOS: Describir las características epidemiológicas, clínicas, analíticas y microbiológicas, así como evaluar la presencia de SHF, en pacientes con HD-VIH. MÉTODOS: Estudio retrospectivo de serie de casos, consistente en la revisión de registros clínicos de pacientes con diagnóstico de HD e infección VIH, durante los años 2014 y 2015. RESULTADOS: El 1,3% (8/597) de los pacientes VIH presentaron HD. El 100% se hallaban en estadio C3 y el 75% (6/8) no se encontraban en terapia antirretroviral combinada (TARVc). Los dos pacientes restantes habían comenzado recientemente el tratamiento con TARVc (posible síndrome de reconstitución inmunológica). El 62,5% (5/8) cumplieron con criterios diagnósticos de SHF. Las manifestaciones clínicas más frecuentes fueron el síndrome linfoproliferativo y consuntivo, el compromiso respiratorio y la citopenia. En el 75% (6/8) de los pacientes se aisló Histoplasma en ganglios, en el 25% (2/8) en muestras hemáticas y en uno adicionalmente en tejido intestinal. La terapia antifúngica fue anfotericina B desoxicolato; no se emplearon adyuvantes. La mortalidad global fue del 50%. CONCLUSIONES: En nuestra serie la coinfección HD-VIH progresó en la mayoría de los casos a SHF con elevada mortalidad. El cuadro clínico puede asemejarse al de otras enfermedades sistémicas, como la tuberculosis, o presentarse simultáneamente a ellas. Con el fin de obtener un diagnóstico precoz y poder prescribir la terapia específica oportuna es importante poseer un adecuado índice de sospecha en pacientes con síndrome linfoproliferativo y consuntivo asociado a citopenia grave

BACKGROUND: Disseminated histoplasmosis (DH) is an opportunistic fungal infection in severely immunocompromised patients with HIV infection. Haemophagocytic syndrome (HFS), which can occur in these co-infected patients when the immune response is significantly altered, is often associated with high mortality. AIMS: To describe the epidemiological, clinical, analytical and microbiological characteristics, along with studying the presence of HFS, in patients with DH-HIV. METHODS: A retrospective study was conducted on a case series using data from the clinical records of patients diagnosed with DH and HIV infection during the years 2014 and 2015. RESULTS: DH was diagnosed in 8 (1.3%) of 597 HIV patients. All patients were in stage C3, and 75% (6/8) were not receiving combined antiretroviral therapy (CART). The remaining two patients had recently begun CART (possible immune reconstitution syndrome). Five (62.5%) of the 8 patients met criteria for HFS. The most frequent clinical symptoms were lymphoproliferative and consumptive syndrome, respiratory compromise, and cytopenia. Histoplasma was isolated in lymph nodes of 75% (6/8) of the patients, in blood samples in 25% (2/8), and also in intestinal tissue in one patient. The antifungal therapy was amphotericin B deoxycholate, without adjuvants. The overall mortality was 50%. CONCLUSIONS: In this case series, DH-HIV co-infection frequently progressed to HFS with high mortality. The clinical picture may resemble that of other systemic opportunistic infections, such as tuberculosis, or can take place simultaneously with other infections. Clinical suspicion is important in patients with severe cytopenia and lymphoproliferative and consumptive syndrome in order to establish an early diagnosis and prescribing a timely specific therapy

[Malaria in HIV-Infected patients: a series of cases in a peruvian hospital]. / Malaria en pacientes con infección por VIH: serie de casos en un hospital peruano.

The clinical signs of malaria in HIV patients may vary depending on the immunological status of the patient. Nationally, evidence regarding co-infection is scarce. This research describes four cases from a hospital in Iquitos, Peru, of patients diagnosed with HIV infection and a positive blood test for malaria. Two of these patients had Plasmodium falciparum infection, and two had Plasmodium vivax infection. One of the patients was in the AIDS stage with poor adherence to combination antiretroviral therapy (cART), and the other three were in the early stages and not receiving cART.

Las manifestaciones clínicas de la malaria en pacientes con VIH pueden ser variables dependiendo del estado inmunológico del paciente. La evidencia en relación a la coinfección es escasa a nivel nacional. Se describen cuatro casos procedentes de un hospital de Iquitos-Perú con diagnóstico de infección por VIH y examen de sangre positivo para malaria. De estos pacientes, dos tenían infección por Plasmodium falciparum y dos por Plasmodium vivax. Un paciente se encontraba en estadio sida con mala adherencia a la terapia antirretroviral combinada (TARVc) y el resto se encontraba en estadios tempranos sin recibir TARVc.

The emergence of Enterobacteria producing carbapenemases of type New Delhi Metalo beta-lactamases (NDM), >represent, today, a real problem of world public health. The presence of this resistance mechanism limits or nullifies the therapeutic options to combat these bacteria. In Latin America, the figures are getting higher, as they are reported in Guatemala, Colombia, Chile, Argentina, among others. Peru has not, to date, described the presence of this resistance pattern; however for several years it has been presumed to exist. Nine cases of Klebsiella pneumoniae NDM are described, as infectious or colonizing agents, in critically ill patients, mostly with neurosurgical pathology, of Hospital Nacional Dos de Mayo in Lima - Peru. The patients in the series described below represent the first reports of Klebsiella pneumoniae NDM in Peru.
