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

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, 45 (52.9%) had persistent splenomegaly, with a median persistence of 14.7 months (range 6.0-27.9 months). Of the 112 patients with available results, 65 (58.0%) patients had evidence of malaria infection, and the mean splenomegaly duration did not differ by Plasmodium species. Refugees with splenomegaly on arrival were 43% more likely to have anemia (adjusted relative risk [aRR]: 1.43, 95% CI: 1.04-1.97). Those with persistent splenomegaly were 60% more likely (adjusted relative risk [aRR]: 1.60, 95% CI: 1.15-2.23) to have a hematologic abnormality, particularly thrombocytopenia (aRR: 5.53, 95% CI: 1.73-17.62), and elevated alkaline phosphatase (aRR: 1.57, 95% CI: 1.03-2.40). Many patients experienced persistent splenomegaly, contradicting literature describing resolution after treatment and removal from an endemic setting. Other possible etiologies should be investigated and effective treatment, beyond treatment for malaria and schistosomiasis, explored.

Determining Physical and Mental Health Conditions Present in Older Adult Refugees: A Mini-Review.

In 2017, there were over 65 million displaced persons at the global level, with approximately 23 million of these people living as refugees around the world. In this same year, the US resettled 53,716 refugees, with the State of Utah receiving 954 of those refugees. Refugees, in general, often face health-related challenges upon resettlement. Since the health of aging refugee men and women is of growing concern, host communities face significant challenges in accommodating the health needs of a diverse refugee population. This study, a review of physical and mental health data from the Utah Department of Health, was undertaken in an effort to ascertain the prevalence of health conditions among refugee men and women 60 years and older arriving in Utah. Findings include information on diseases correlated with increasing age, such as hypertension, decreases in vision, arthritis, and low back pain, which are common among this population of refugees aged 60 years and older. Overall, most of the health conditions assessed affect women and men with a similar prevalence. Some notable exceptions are a history of torture and violence, and a propensity for tobacco use. When dealing with refugee men older than 60 years, providers should consider the psychological ramifications of having endured such atrocities, as well as introduction to evidence-based tobacco cessation programs. When working with refugee women of the same age, an increase in the prevalence of musculoskeletal pain and urinary tract infections should be considered.

Unresolved Splenomegaly in Recently Resettled Congolese Refugees - Multiple States, 2015-2018.

In 2014, panel physicians from the International Organization for Migration (IOM), who conduct Department of State-required predeparture examinations for U.S.-bound refugees at resettlement sites in Uganda, noticed an unusually high number of Congolese refugees with enlarged spleens, or splenomegaly. Many conditions can cause splenomegaly, such as various infections, liver disease, and cancer. Splenomegaly can result in hematologic disturbances and abdominal pain and can increase the risk for splenic rupture from blunt trauma, resulting in life-threatening internal bleeding. On CDC's advice, panel physicians implemented an enhanced surveillance and treatment protocol that included screening for malaria (through thick and thin smears and rapid diagnostic testing), schistosomiasis, and several other conditions; treatment of any condition identified as potentially associated with splenomegaly; and empiric treatment for the most likely etiologies, including malaria and schistosomiasis. CDC recommended further treatment for malaria with primaquine after arrival, after glucose-6-phosphate dehydrogenase testing, to target liver-stage parasites. Despite this recommended treatment protocol, 35 of 64 patients with available follow-up records had splenomegaly that persisted beyond 6 months after resettlement. Among 85 patients who were diagnosed with splenomegaly through abdominal palpation or ultrasound at any point after resettlement, 53 had some hematologic abnormality (leukopenia, anemia, or thrombocytopenia), 16 had evidence of current or recent malaria infection, and eight had evidence of schistosomiasis. Even though primaquine was provided to a minority of patients in this cohort, it should be provided to all eligible patients with persistent splenomegaly, and repeated antischistosomal therapy should be provided to patients with evidence of current or recent schistosomiasis. Given substantial evidence of familial clustering of cases, family members of patients with known splenomegaly should be proactively screened for this condition.
