Invasive pulmonary aspergillosis still constitutes a diagnostic challenge for clinicians due to its non-specific symptoms. HIV infection represents one of the major risk factors due to the progressive failure of the immune system. In this study, Aspergillus serum galactomannan enzyme linked immunosorbent assay was used for the diagnosis of invasive pulmonary aspergillosis in patients living with HIV/AIDS attending University of Ilorin Teaching Hospital Antiretroviral Therapy Clinic, Nigeria. Blood samples were collected from 97 patients affected by HIV/AIDS. Age range of the study population was between 0 and 79 years. Length of the study: 3 weeks. Three out of the 97 samples were positive for the galactomannan assay with an optical density index of 1.1, 0.9 and 1.1 using the 0.5 cut-off optical density value; the concentration level of galactomannan antigen was therefore 2.20 μg/L, 1 μg/L and 2.19 μg/L, respectively. A prevalence of 3.1 % (3/97) was detected; all positive participants have been on ART for more than 3 years (P<0.0001), and 2 out of the 3 had CD4 count higher than 200 cells/mm3 (P<0.0001). Serum Aspergillus galactomannan assay is less invasive for patients and diagnosis can be made in a relatively shorter time compared to other techniques used in diagnosing invasive pulmonary aspergillosis.

Abstract Background Invasive pulmonary aspergillosis (IPA) is a life-threatening opportunistic infection which usually occurs in immunocompromised patients. Recommended duration of voriconazole therapy is a minimum of 6-12 weeks for IPA, despite the lack of any firm evidence. In addition, risk factors for relapse of IPA are still unclear. Here, we explored risk factors for IPA relapse after initial treatment. Methods All patients with proven or probable IPA who had finished voriconazole treatment between 2005 and 2019 in a tertiary-care hospital were reviewed. IPA relapse was defined as re-diagnosis of proven or probable IPA at the same site within 1 year after treatment termination. Short course of voriconazole treatment was defined as a treatment less than 9 weeks, which is a median of the recommended minimum duration of therapy from the Infectious Disease Society of America. The radiological response was defined as a reduction in IPA burden by more than 50% on chest computed tomography (CT). Results Of 87 patients who had completed voriconazole treatment, 14 (16.1%) experienced IPA relapse. Multivariable Cox regression identified that short voriconazole treatment duration (adjusted hazard ratio [aHR], 3.7; 95% confidence interval [CI], 1.1–12.3; P=0.033) and radiological non-response (aHR, 4.6; 95% CI, 1.2–17.5; P=0.026) were independently associated with relapse of IPA after adjusting for several clinical risk factors. Conclusion Less improvement in CT, and short duration of voriconazole therapy were the independent risk factors for relapse after treatment of IPA. Longer duration of therapy should be considered for those at higher risk of relapse. Disclosures All Authors: No reported disclosures

AbstractA cross-sectional study was carried out to determine the seroprevalence of Toxoplasma gondii and associated risk factors in pigs in the largest pork-producing region in Cuba. Serum samples from 420 pigs, including 210 sows and 210 post-weaning pigs, were tested for antibodies against T. gondii using a commercial indirect enzyme-linked immunosorbent assay. Anti-T. gondii antibodies were detected in 56 animals (13.3%, 95% CI: 10.1–16.6). A generalized estimating equations model revealed that the risk factors associated with higher seropositivity in pigs were altitude (higher in farm’s location < 250 m above sea level (masl) versus ≥ 250 masl) and age (higher in sows compared to post-weaning pigs). The results indicated that this protozoan parasite is widely distributed on pig farms in the study area, which is a public health concern since the consumption of raw or undercooked pork meat products containing tissue cysts is considered one of the main routes of T. gondii transmission worldwide. Control measures should be implemented to reduce the risk of exposure to T. gondii in pigs in Cuba.

Associated Risk Factors

Contagious bovine pleuropneumonia (CBPP) is an important infectious disease of respiratory system of cattle, caused by Mycoplasma mycoides subspecies mycoides. A cross sectional study was conducted in Lahore, Kasur and Jhang districts of Punjab to determine the prevalence of CBPP. A total of 560 serum samples were examined for the specific antibodies against M. mycoides subspecies mycoides, using a sandwich enzyme-linked immunosorbent assay. Associated risk factors that were evaluated include age, gender and breed. In this study, the overall seroprevalence was 8.75%. The seroprevalence of CBPP in Lahore, Kasur and Jhang were 8.26, 8.20 and 10.06%, respectively, but no significance difference (P less than 0.05) was observed. Among the assessed potential predisposing factors, gender and breed were not significantly associated with the serological status of the animal (P greater than 0.05), in which the age affected significantly the positivity to CBPP (P less than 0.05). The highest seropositivity was observed in animals of more than 7 years of age (32.08%) followed by in 4-7 years of age (8.16%) and lowest in animals of less than 4 years old (0.79%). This study confirms the presence of CBPP in the state which could be a threat to livestock export market and warrants the implementation of control measures to mitigate the economic losses associated with the disease.
