Bottom Line: Leishmaniasis-HIV co-infection was significantly associated with male sex (aOR=1.6; 95% CI: 1.25-2.04), 16-64 years age group (aOR=17.4; 95%CI: 2.1-143.3), visceral leishmaniasis aOR=6.1 (95%CI: 3.27-11.28) and solid neoplasms 4.5 (95% CI: 1.65-12.04).The absence of HIV co-infection was associated with lymph/hematopoietic neoplasms (aOR=0.3; 95%CI:0.14-0.57), other immunodeficiency (aOR=0.04; 95% CI:0.01-0.32) and transplant (aOR=0.01; 95%CI:0.00-0.07).Our findings suggest a significant increase of hospitalization in the absence of HIV co-infection, with a predomination of VL.

ABSTRACT
In Spain, Leishmania infantum is endemic, human visceral and cutaneous leishmaniasis cases occurring both in the Peninsula, as well as in the Balearic Islands. We aimed to describe the clinical characteristics of leishmaniasis patients and the changes in the disease evolution after the introduction of antiretroviral therapy in 1997. In this descriptive study, we used Spanish Centralized Hospital Discharge Database for the hospitalized leishmaniasis cases between 1997 and 2011. We included in the analysis only the records having leishmaniasis as the first registered diagnosis and calculated the hospitalization rates. Disease trend was described taking into account the HIV status. Adjusted odds-ratio was used to estimate the association between clinical and socio-demographic factors and HIV co-infection. Of the total 8010 Leishmaniasis hospitalizations records, 3442 had leishmaniasis as first diagnosis; 2545/3442 (75.6%) were males and 2240/3442 (65.1%) aged between 14-65 years. Regarding disease forms, 2844/3442 (82.6%) of hospitalizations were due to visceral leishmaniasis (VL), while 118/3442 (3.4%) hospitalizations were cutaneous leishmaniasis (CL). Overall, 1737/2844 of VL (61.1%) were HIV negatives. An overall increasing trend was observed for the records with leishmaniasis as first diagnosis (p=0.113). Non-HIV leishmaniasis increased during this time period (p=0.021) while leishmaniasis-HIV co-infection hospitalization revealed a slight descending trend (p=0.717). Leishmaniasis-HIV co-infection was significantly associated with male sex (aOR=1.6; 95% CI: 1.25-2.04), 16-64 years age group (aOR=17.4; 95%CI: 2.1-143.3), visceral leishmaniasis aOR=6.1 (95%CI: 3.27-11.28) and solid neoplasms 4.5 (95% CI: 1.65-12.04). The absence of HIV co-infection was associated with lymph/hematopoietic neoplasms (aOR=0.3; 95%CI:0.14-0.57), other immunodeficiency (aOR=0.04; 95% CI:0.01-0.32) and transplant (aOR=0.01; 95%CI:0.00-0.07). Our findings suggest a significant increase of hospitalization in the absence of HIV co-infection, with a predomination of VL. We consider that clinicians in Spain should be aware of leishmaniasis not only in the HIV population but also in non HIV patients, especially for those having immunosuppression as an associate condition.

pntd.0003594.g001: Temporal trend of hospitalizations with leishmaniasis as first diagnosis rates by HIV status, 1997–2011, Spain.

Mentions: The temporal distribution of hospitalizations related to leishmaniasis as first diagnosis during the 15-year study period is represented in Fig. 1. At the national level, the median annual hospitalization rate was 5.6/1 million population (range 3.2–6.6/1 million population). The median annual hospitalization rate for hospitalized leishmaniasis-HIV co-infection was 1.9 (range 1.5 to 2.5), while for leishmaniasis hospitalizations without an HIV diagnosis was 3.4/1 million population (range 1.7 to 4.7). From 1997 to 2011, an increasing trend in the rates of hospitalizations with leishmaniasis as first diagnosis was observed (p = 0.113). Non-HIV leishmaniasis has also increased during this time period (p = 0.021) while leishmaniasis-HIV co-infection hospitalization revealed a slight descending trend (p = 0.717). These trends were similar to those observed when assessing all leishmaniasis related hospitalizations (n = 8010), with exception to the trend for the total population (regardless the HIV status), which shown a slightly descending trend (S1 Fig).
