Clinical Spectrum of Schistosomiasis: An Update.

Schistosomiasis is a helminthic infection and one of the neglected tropical diseases (NTDs). It is caused by blood flukes of the genus Schistosoma. It is an important public health problem, particularly in poverty-stricken areas, especially those within the tropics and subtropics. It is estimated that at least 236 million people worldwide are infected, 90% of them in sub-Saharan Africa, and that this disease causes approximately 300,000 deaths annually. The clinical manifestations are varied and affect practically all organs. There are substantial differences in the clinical presentation, depending on the phase and clinical form of schistosomiasis in which it occurs. Schistosomiasis can remain undiagnosed for a long period of time, with secondary clinical lesion. Here, we review the clinical profile of schistosomiasis. This information may aid in the development of more efficacious treatments and improved disease prognosis.

Epidemiology of aspergillosis in hospitalised Spanish patients-A 21-year retrospective study.

BACKGROUND: Aspergillosis is a serious infection, and in Spain, the influence of epidemiology and climate on the resulting expenses of aspergillosis is not well established. AIM: A retrospective descriptive study using the Minimum Basic Data Set was performed on records of patients admitted to hospitals of the National Health System between 1997 and 2017 with a diagnosis of aspergillosis. The weather parameters were obtained from the State Agency of Meteorology from Spain. RESULTS: A total of 32,960 patients were identified, of whom 22,383 were men (68%). The mean age (±SD) was 61.1 ± 19.1 years. The mean incidence rate for all diagnoses was 3.54 cases per 100,000 person-years (95% CI, 3.50-3.57). The incidence rate in men was twice as high as that in women, 4.89 (95% CI, 4.82-4.95) vs. 2.24 (95% CI, 2.19-2.27) cases per 100,000 person-years (p > .001). The highest incidence rates were concentrated in northern Spain. One in four patients died (8,080 cases; 25%). There was a moderate positive linear association between rainfall and incidence rate (rP  = .508; p = .026). In contrast, the Pearson's correlation coefficient indicated a moderate negative linear relationship between temperature and incidence rate (rP  = -.447; p = .050). We observed a higher incidence in the months with higher humidity and rainfall. CONCLUSIONS: Our study supports a high burden of aspergillosis in Spain, with an increase in cases in the past two decades. Additionally, the influence of climatological factors on the incidence of aspergillosis is highlighted. Despite preemptive treatment strategies, this infection still has a high mortality.

Eosinophilia and cystic echinococcosis: what is the relationship?

BACKGROUND: Cystic echinococcosis (CE) is a chronic, complex and neglected zoonotic disease caused by Echinococcus granulosus. Eosinophilia in CE is a classic analytic alteration, although its presentation and importance is very variable and not well established. METHODS: We performed a retrospective observational study of inpatients diagnosed with CE and eosinophilia from January 1998 to December 2017 in the Complejo Asistencial Universitario de Salamanca in western Spain. RESULTS: During the study period, 475 patients with a CE diagnosis underwent a haemogram and 118 (24.8%) patients had eosinophilia. Eighty-two (69.5%) were male and the mean age was 52.1±20.8 y, which was younger in the group with eosinophilia (p<0.001). The patients with eosinophilia had less comorbidity (33.1% vs 52.9%; p<0.001) and they were diagnosed with more complications (60.2% vs 39.8% asymptomatic; p<0.001). Clinical manifestations appeared in 71 cases (60.2%). The eosinophilia was related to the presence of pre-surgical fistulas (p=0.005). We observed significant differences when considering whether eosinophilia is a marker of the type of treatment (p<0.001). CONCLUSIONS: Eosinophilia can be an indicator for an active search in CE because as much as 40% of cases are asymptomatic at diagnosis. In patients with eosinophilia, management is usually more aggressive and is usually a combined treatment. Our work shows the importance of eosinophilia in our patients with CE and raises unresolved questions.

Pylephlebitis: Incidence and prognosis in a tertiary hospital / Pileflefitis: incidencia y prognosis en un hospital terciario

OBJECTIVES: Septic thrombophlebitis of the portal vein or its branches, most often secondary to intra-abdominal infection is known as pylephlebitis. The frequency and the prognosis of this complication are unknown. The aim of this study was to determine the global and relative incidence of the most frequent intra-abdominal infections and the real prognosis of this disease. Methods An observational retrospective study was conducted in a tertiary care hospital (University Hospital of Salamanca, Spain) from January 1999 to December 2008.ResultsA total of 7796 patients with intra-abdominal infection were evaluated, of whom 13 (0.6%) had been diagnosed with pylephlebitis. Diverticulitis was the most frequent underlying process, followed by biliary infection. Early mortality was 23%. Survivors had no recurrences, but one of them developed portal cavernomatosis. Conclusions Pylephlebitis is a rare complication of intra-abdominal infection, with a high early mortality, but with a good prognosis for survivors

OBJETIVOS: La tromboflebitis séptica de la vena porta o de sus ramas se conoce como pileflebitis. En la mayoría de ocasiones es secundaria a infecciones intraabdominales. La frecuencia y el pronóstico deesta complicación infecciosa no son conocidas. El objetivo de este estudio es describir la incidenciaglobal, relativa y el pronóstico real de esta enfermedad respecto a las infecciones intraabdominales más frecuentes. MÉTODOS: Estudio observacional retrospectivo en un hospital de tercer nivel (Hospital Universitario de Salamanca) desde enero de 1999 a diciembre de 2008.RESULTADOS: Se evaluó a 7.796 pacientes con infecciones intraabdominales. Trece (0,6%) fueron diagnosticados de pileflebitis. La diverticulitis fue el proceso subyacente más frecuente, seguida de la infección biliar. La mortalidad precoz fue del 23%. Los pacientes que sobrevivieron no presentaron recurrencias, pero uno de ellos desarrolló una cavernomatosis portal. CONCLUSIONES: La pileflebitis es una complicación poco frecuente de las infecciones intraabdominales. Presenta una elevada mortalidad precoz, pero tiene un buen pronóstico vital para los pacientes que sobreviven

Study of hydatidosis-attributed mortality in endemic area.

BACKGROUND: Cystic hydatid disease is still an important health problem in European Mediterranean areas. In spite of being traditionally considered as a "benign" pathology, cystic echinococcosis is an important cause of morbidity in these areas. Nevertheless, there are few analyses of mortality attributed to human hydatidosis. OBJECTIVE: To describe the epidemiology, the mortality rate and the causes of mortality due to E. granulosus infection in an endemic area. METHODOLOGY: A retrospective study followed up over a period of 14 years (1998-2011). PRINCIPAL FINDINGS: Of the 567 patients diagnosed with hydatid disease over the period 1998-2011, eleven deaths directly related to hydatid disease complications were recorded. Ten patients (90.9%) died due to infectious complications and the remaining one (9.1%) died due to mechanical complications after a massive hemoptysis. We registered a case fatality rate of 1.94% and a mortality rate of 3.1 per 100.000 inhabitants. CONCLUSIONS: Hydatidosis is still a frequent parasitic disease that causes a considerable mortality. The main causes of mortality in patients with hydatidosis are complications related to the rupture of CE cysts with supurative collangitis. Therefore, an expectant management can be dangerous and it must be only employed in well-selected patients.
