ABSTRACT Background: Invasive fungal infections (IFIs) affect >1.5 million people per year. Nevertheless, IFIs are usually neglected and underdiagnosed. IFIs should be considered as a public-health problem and major actions should be taken to tackle them and their associated costs. Aim To report the incidence of IFIs in four Mexican hospitals, to describe the economic cost associated with IFIs therapy and the impact of adverse events such as acute kidney injury (AKI), liver damage (LD), and ICU stay. Methods: This was a retrospective, transversal study carried-out in four Mexican hospitals. All IFIs occurring during 2016 were included. Incidence rates and estimation of antifungal therapy's expenditure for one year were calculated. Adjustments for costs of AKI were done. An analysis of factors associated with death, AKI, and LD was performed. Results: Two-hundred thirty-eight cases were included. Among all cases, AKI was diagnosed in 16%, LD in 25%, 35% required ICU stay, with a 23% overall mortality rate. AKI and LD showed higher mortality rates (39% vs 9% and 44% vs 18%, respectively, p < 0.0001). The overall incidence of IFIs was 4.8 cases (95% CI = 0.72–8.92) per 1000 discharges and 0.7 cases (95% CI = 0.03–1.16) per 1000 patients-days. Invasive candidiasis showed the highest incidence rate (1.93 per 1000 discharges, 95% CI = −1.01 to 2.84), followed by endemic IFIs (1.53 per 1000 discharges 95% CI = −3.36 to 6.4) and IA (1.25 per 1000 discharges, 95% CI = −0.90 to 3.45). AKI increased the cost of antifungal therapy 4.3-fold. The total expenditure in antifungal therapy for all IFIs, adjusting for AKI, was $233,435,536 USD (95% CI $6,224,993 to $773,810,330). Conclusions: IFIs are as frequent as HIV asymptomatic infection and tuberculosis. Costs estimations allow to assess cost-avoidance strategies to increase targeted driven therapy and decrease adverse events and their costs.

Abstract: Background: Pneumocystis pneumonia caused by Pneumocystis jirovecii is one of the most devastating fungal diseases in patients with impaired immunity. Effective antiviral therapies have reduced the burden of PJ in patients with AIDS, but increase in the prevalence of this disease among HIV-negative people receiving immunosuppressive treatments currently reported. Case report: Female 68, diabetic, hypertensive controlled, with 15 years of evolution of rheumatoid arthritis, managed with steroids and methotrexate, which has completed multiple hospitalizations in the last four months by lung disease characterized by dyspnea, dry cough and fever, TAC showing cryptogenic interstitial lung disease, with foci of consolidation and pulmonary fibrosis, transbronchial biopsy and PCR positive for Pneumocystis jirovecii. Handled with trimethoprim-sulfamethoxazole and steroid boluses, improving significantly in 11 days of hospitalization. Conclusions: Real-time PCR is a useful tool for the diagnosis of Pneumocystis pneumonia in non-HIV patients. Hence, a positive Pneumocystis real-time PCR should be taken into account even if the patient does not have symptoms, but has a risk factor like cancer, hematological disorder and/or receives an immunosuppressive therapy.

Resumen: Antecedentes: La neumonía por neumocistosis originada por Pneumocystis jirovecii es una de las enfermedades fúngicas más devastadoras en pacientes con alteraciones de la inmunidad. Las terapias antivirales eficaces han reducido la carga de la PJ en pacientes con SIDA, pero actualmente se reporta incremento en la prevalencia de esta enfermedad entre las personas VIH negativas que reciben tratamientos con inmunosupresores. Caso clínico: Paciente femenino de 68 años, diabética, hipertensa controlada, con 15 años de evolución de artritis reumatoide, manejada con esteroides y metotrexate, que ha cursado con múltiples hospitalizaciones en los últimos cuatro meses por neumopatía caracterizada por disnea, tos seca y fiebre, con TAC que muestra neumopatía intersticial criptogénica, con focos de consolidación y fibrosis pulmonar, con biopsia transbronquial y PCR positiva para Pneumocystis jirovecii. Es manejada con trimetoprima-sulfametoxazol y bolos de esteroides, mejorando ostensiblemente en 11 días de hospitalización. Conclusiones: El PCR en tiempo real es la herramienta más útil para el diagnóstico de la neumonía por Pneumocystis, por lo que debe efectuarse incluso en pacientes que no tienen síntomas, pero presentan factores de riesgo como cáncer, trastornos hematológicos u otras enfermedades inmunológicas y/o reciben terapia inmunosupresora.

Objective. To establish the characteristics and causes of death of HIV patients who die while hospitalized. Materials and methods. We included HIV+ patients who died during hospitalization, in three hospitals in Mexico City between 2010 and 2013. Sociodemographic and clinical data were collected as well as causes of death. We identified preventable deaths (defined as deaths that occurred in patients with less than six months of HAART, or without HAART, with less than 350 CD4 at diagnosis and/or opportunistic events as the cause of hospitalization). Results. 128 deaths were analyzed. The median of CD4 count was 47 cells/mm³; 18% of the patients ignored their HIV status at the time of hospitalization, 51% had less than six months of HAART, 40.5% had never received HAART before. The main causes of death were AIDS defining events, with 65.6%. We identified 70 preventable deaths (57%). Conclusions. Despite universal access to HAART, HIV patients in Mexico are still dying of AIDS defining illnesses, an indicator of late diagnosis. It is urgent to implement HIV testing programs to allow earlier diagnosis and make HAART benefit accessible to all.

Objetivo. Establecer las características y causas de muerte de pacientes VIH positivos que fallecen al estar hospitalizados. Material y métodos. Se incluyeron pacientes VIH positivos que fallecieron durante la hospitalización entre 2010 y 2013. Se recabaron datos sociodemográficos y clínicos, causas de muerte y muertes prevenibles. Se consideraron prevenibles aquellas muertes en pacientes con menos de seis meses de terapia antirretroviral altamente activa (TARAA) o sin tratamiento y con menos de 350 CD4+ al momento del diagnóstico o del internamiento, con o sin enfermedades oportunistas. Resultados. Se identificaron 128 muertes. La mediana de CD4+ fue 47 cels/mm³; 18% llegó al internamiento sin diagnóstico de VIH, 51% tenía menos de seis meses de haber sido diagnosticado y 40.5% no había recibido TARAA. Las principales causas de muerte fueron eventos definitorios de sida (65.6%). Se identificaron 70 muertes prevenibles (57%). Conclusión. A pesar del acceso universal a TARAA, en México los pacientes VIH positivos siguen falleciendo por eventos relacionados con sida, que es un indicador de diagnóstico tardío del VIH. Es urgente implementar programas de detección temprana para hacer accesible el beneficio de la TARAA.
