Clinical Sequelae Associated with Unresolved Tropical Splenomegaly in a Cohort of Recently Resettled Congolese Refugees in the United States-Multiple States, 2015-2018.

Clinical Sequelae Associated with Unresolved Tropical Splenomegaly in a Cohort of Recently Resettled Congolese Refugees in the United States-Multiple States, 2015-2018. Am J Trop Med Hyg. 2020 May 04;: Authors: Zambrano LD, Jentes E, Phares C, Weinberg M, Kachur SP, Basnet MS, Klosovsky A, Mwesigwa M, Naoum M, Nsobya SL, Samson O, Goers M, McDonald R, Morawski B, Njuguna H, Peak C, Laws R, Bakhsh Y, Iverson SA, Bezold C, Allkhenfr H, Horth R, Yang J, Miller S, Kacka M, Davids A, Mortimer M, Stauffer W, Marano N Abstract Tropical splenomegaly is often associated with malaria and schistosomiasis. In 2014 and 2015, 145 Congolese refugees in western Uganda diagnosed with splenomegaly during predeparture medical examinations underwent enhanced screening for various etiologies. After anecdotal reports of unresolved splenomegaly and complications after U.S. arrival, patients were reassessed to describe long-term clinical progression after arrival in the United States. Post-arrival medical information was obtained through medical chart abstraction in collaboration with state health partners in nine participating states. We evaluated observed splenomegaly duration and associated clinical sequelae between 130 case patients from eastern Congo and 102 controls through adjusted hierarchical Poisson models, accounting for familial clustering. Of the 130 case patients, 95 (73.1%) had detectable splenomegaly after arrival. Of the 85 patients with records beyond 6 months...

Abstract The kingdom of Saudi Arabia (KSA) has succeeded in bringing the reported numbers of Visceral leishmaniasis (VL) cases from hundreds during the 1980s and 1990s to zero case in 2019. The endemicity of VL has been confined mainly to the Southwest regions, namely Jazan and Aseer regions. Leishmania donovani species have been identified as the causative species of VL, while L. infantum have been isolated only from dogs in the endemic areas. Many species of sand flies were caught in Southwest, but P. orientalis is the probable transmitter of the disease. The black rat (Rattus ratus) was found to be contributing...

Authors: Omarine Nlinwe N, Nange TB Abstract Malaria, which is responsible for a substantial amount of deaths in endemic countries, has been shown to have both direct and indirect effects on the hematological parameters. Notwithstanding, some hematological parameters among populations living in malaria endemic regions have not been described consistently, as a standard for measuring malaria burden. Based on the above fact, this study was designed to assess some hematological changes and their diagnostic values in malaria infected patients. A total of 160 malaria positive adult patients, together with 81 healthy con...

Conclusions: Severe malaria is a highly frequent event in pregnant women, without differences by Plasmodium species. It shows early recognizable dangers signs. Hospital under-reporting was identified in 88% of severe cases as well as a lack of laboratory tests for a more comprehensive diagnosis. A protocol for the clinical diagnosis of pregnant women with malaria is required. PMID: 31529822 [PubMed - in process]

Conclusion: Despite increasing incidence of imported malaria in our country in recent years, there is a decrease in this number in our region. Since Turkey is one of the countries with the highest prevalence of imported malaria in the world, patients with fever and thrombocytopenia should be questioned whether or not they had a history of travel to malaria-endemic area.

Conclusion and Future Directions The ECM model has produced a wealth of information on CM pathogenesis in mice with the aim to find an adjunctive therapy for HCM but its validity has been questioned. However, several investigators have provided a critical and evidence-based defense of this model (17, 128–131) and from knowledge gained from it, numerous laboratories have tested preclinical therapeutic interventions. Many have demonstrated efficacy at blocking the development of ECM but disappointingly, in a majority of cases, this was only found when administered before or early post infection and prior to the onset ...

Conclusions Nucleoside hydrolases are vital enzymes for the replication of Leishmania, conserved phylogenetic marker of the genus and strong-specific immunogens. We demonstrated that NH36 is an excellent target for chemotherapy of visceral leishmaniasis. Searching for the most immunogenic fraction of promastigotes of Leishmania we described the FML antigen of L. (L.) donovani, that has as its main component, the NH36 Nucleoside hydrolase. We developed second–generation vaccines with the FML and the NH36 native antigens, and with the NH36 recombinant protein. In addition, we obtained a third generation vaccine based ...

Abstract Dakshina Kannada district in the Southwestern region of Karnataka state, India, including Mangaluru city is endemic to malaria. About 80% of malaria infections in Mangaluru and its surrounding areas are caused by Plasmodium vivax and the remainder is due to Plasmodium falciparum. Malaria-associated clinical complications significantly occur in this region. Here, we report the pathological conditions of 41 cases of fatal severe malaria, admitted to the district government hospital in Mangaluru city during January 2013 through December 2016. The results of clinical, hematological, and biochemical analyses s...

Hemophagocytic Lymphohistiocytosis (HLH) is characterized by pathologic immune activation which occurs either as a familial disorder or as an acquired condition. The diagnosis of HLH requires the presence of five out of nine criteria: fever, splenomegaly, pancytopenia, hypertriglyceridemia, hypofibrinogenemia, hemophagocytosis in bone marrow, hyperferritinemia, low or absent natural killer cell activity and high level of soluble interleukin-2 receptor.Here we present a 6-month-old girl with parents from Southern Italy. She suffered from hepatosplenomegaly and a recurrent high fever for 3 months' duration. On admission, she...

Abstract The extent of abnormalities in blood indices and their subsequent effects on clinical severity in malaria differ among populations of different endemicity. However, these alterations have not been well investigated in Odisha, India and their prognostic implications in the context of multi-organ dysfunction (MODS) in severe malaria (SM) are not identified so far. The present study was carried out in 200 adult patients each from uncomplicated malaria and severe malaria groups to examine whether host haematological and biochemical parameters in Plasmodium falciparum infection can act as diagnostic marker for...

We report a case of delayed diagnosis of CM by P. vivax in a newborn of an Eritrean primigravida. The mother developed pregnancy-related immunodepression and varicella-zoster viral infection 9 days before natural delivery; therefore, the child was admitted in the neonatal intensive care unit (NICU) to administer specific varicella-zoster immunoglobulin prophylaxis and for clinical monitoring. During the NICU stay, the newborn presented a febrile syndrome with vomiting, anemia, and thrombocytopenia. A P. vivax severe malaria diagnosis was made by detecting trophozoites in the thick and thin blood smears. The infant was succ...
