ABSTRACT
INTRODUCTION: Japanese spotted fever (JSF) mainly occurs in Japan; however, it has been increasingly reported in China. JSF is typically characterized by fever, rash, and eschar, in addition to non-specific symptoms. Yet, reports on the pulmonary indicators in JSF are limited. Herein, we report an unusual case of JSF associated with pleural effusion and pneumonia, in which the pathogen was identified via blood next-generation sequencing (NGS). CASE PRESENTATION: We report a case of a 33-year-old woman who presented with fever for five days, rash for two days, and myalgia, fatigue, and edema for one day. She had recently been on vacation when an unknown insect bit her. The doctors at the local primary hospital considered a bacterial infection and administered dexamethasone, ceftriaxone, indomethacin, and anti-allergy agents, but the symptoms persisted. A rash without pruritus or pain developed gradually over the entire body and face. We considered rickettsial infection and administered doxycycline and levofloxacin. Metagenomic NGS from blood confirmed the presence of Rickettsia japonica (R. japonica). Abdominal computed tomography revealed bilateral pleural effusion with two atelectasis; patchy shadows with blurred edges, and uniform enhancement in both lower lungs. After several days of treatment, the symptoms and laboratory results improved. A literature review of the epidemiology of R. japonica and JSF in China, characteristics of JSF, and related pulmonary changes, and technology to diagnose JSF is provided. CONCLUSIONS: JSF has a variety of symptoms and is becoming increasingly popular in China. Clinical doctors need to identify it carefully.

A 58-year-old woman had disseminated intravascular coagulation (DIC) and septic shock caused by Japanese spotted fever (JSF). Following treatment with minocycline, her general condition gradually improved; however, her disorientation persisted. Mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) type II was diagnosed based on brain magnetic resonance imaging (MRI) showing a hyperintense area in the splenium of the corpus callosum and bilateral cerebral white matter on diffusion-weighted imaging. Thereafter, her consciousness gradually improved, but she continued to experience difficulty concentrating and attention deficits. MERS type II may take longer to improve than type I, and long-term follow-up is required.

African tick bite fever, resulting from Rickettsia africae inoculation, is endemic in sub-Saharan Africa. We present a United States traveler with African tick bite fever 5 days after she returned from a mission trip to Zimbabwe. The patient exhibited symptomatic hypotension in addition to more typical findings, including fever, fatigue, and a necrotic eschar. The diagnosis was supported by histopathological findings and the patient's symptoms rapidly resolved with oral doxycycline therapy. We believe this case represents the first African tick bite fever diagnosis associated with symptomatic hypotension. This case additionally serves as a reminder of the importance of evaluating patient travel history.

BACKGROUND: We report a mononucleosis-like illnesses case due to co-infection with severe fever with thrombocytopenia syndrome virus (SFTSV) and spotted fever group rickettsia (SFGR), which to the best of our knowledge, has never been reported . CASE PRESENTATION: A 64-year-old male with an 11-day history of fever, sore throat, malaise, nausea, and non-pruritic rash was admitted to our emergency department. Prior to admission, he was bitten by ticks. Laboratory tests revealed a white blood cell count of 24,460 cells/µL with 25% atypical lymphocytes and 20% mononucleosis, thrombocytopenia. Test results were positive for SFTSV RNA, SFTSV-specific IgM antibody, and SFGR-specific IgM antibody. He was diagnosed with mononucleosis-like illnesses due to co-infection with SFTSV and SFGR. After administration of doxycycline, he recovered completely. CONCLUSIONS: The clinical presentation may be atypical in co-infection with SFTSV and SFGR. This finding highlighted the importance of considering SFGR infection, as well as a SFSTV and SFGR co-infection for the differential diagnosis of patients bitten by ticks in SFTSV-endemic areas.

The Neotropical region shows a great diversity of fleas, comprising more than 50 genera. The importance of the study of fleas is linked to their potential role as disease vectors. The aim of this study is to investigate the presence of Rickettsia spp. and Bartonella spp. in Neotropical fleas collected from wild rodents in Southern Brazil. From 350 rodents captured, 30 were parasitized by fleas. A total of 61 fleas belonging to two genera and six different species were collected (Craneopsylla minerva minerva, Polygenis occidentalis occidentalis, Polygenis platensis, Polygenis pradoi, Polygenis rimatus, and Polygenis roberti roberti). In 13 % of fleas of three different species (C. minerva, P. platensis, and P. pradoi) Rickettsia sp. DNA was found. Phylogenetic analysis of concatenated sequences of gltA, htrA, and ompA genes showed that Rickettsia sp. found in rodent fleas (referred as strain Taim) grouped together with Spotted Fever Group Rickettsia. In reference to Bartonella spp., five genotypes were identified in seven fleas of two species (C. minerva and P. platensis) and in five rodent spleens. Also, 207 frozen samples of wild rodents were screened for these pathogens: while none was positive for Rickettsia spp.; five rodent spleens were PCR-positive for Bartonella spp.. Herein, we show the detection of potential novel variants of Bartonella sp. and Rickettsia sp. in fleas collected of wild rodents from Southern Brazil. Further studies are needed to fully characterize these microorganisms, as well as to improve the knowledge on the potential role of Neotropical flea species as diseases vectors.

Scrub typhus and spotted fever rickettsioses (SFR) are understudied, vector-borne diseases of global significance. Over 1 billion individuals are at risk for scrub typhus alone in an endemic region, spanning across eastern and southern Asia to Northern Australia. While highly treatable, diagnostic challenges make timely antibiotic intervention difficult for these diseases. Delayed therapy may lead to severe outcomes affecting multiple organs, including the central nervous system (CNS), where infection and associated neuroinflammation may be lethal or lead to lasting sequelae. Meningitis and encephalitis are prevalent in both scrub typhus and SFR. Additionally, case reports detailing focal neurological deficits have come to light, with attention to both acute and chronic sequelae of infection. Despite the increasing number of clinical reports outlining neurologic consequences of these diseases, relatively little research has examined underlying mechanisms of neuroinflammation. Animal models of scrub typhus have identified cerebral T-cell infiltration and vascular damage associated with endothelial infection and neuropathogenesis. Differential gene expression analysis of brain tissues during murine scrub typhus have revealed selective increases in CXCR3 ligands, proinflammatory and type-1 cytokines and chemokines, and cytotoxicity molecules, as well as alterations in the complement pathway. In SFR, microglial expansion and macrophage infiltration contribute to neurological disease progression. This narrative Review highlights clinical neurologic features of scrub typhus and SFR and evaluates our current understanding of basic research into neuroinflammation for both diseases in animal models. Further investigation into key mediators of neuropathogenesis may yield prognostic markers and treatment regimens for severe patients.

Scrub typhus and Queensland tick typhus (QTT)-rickettsial infections endemic to tropical Australia-can cause life-threatening disease. This retrospective study examined the clinical course of all patients with laboratory-confirmed scrub typhus or QTT admitted to the intensive care unit (ICU) of a tertiary referral hospital in tropical Australia between 1997 and 2019. Of the 22 patients, 13 had scrub typhus and nine had QTT. The patients' median (interquartile range [IQR]) age was 50 (38-67) years; 14/22 (64%) had no comorbidity. Patients presented a median (IQR) of seven (5-10) days after symptom onset. Median (IQR) Acute Physiology and Chronic Health Evaluation II scores were 13 (9-17) for scrub typhus and 13 (10-15) for QTT cases (P = 0.61). Following hospital admission, the median (IQR) time to ICU admission was five (2-19) hours. The median (IQR, range) length of ICU stay was 4.4 (2.9-15.9, 0.8-33.8) days. Multi-organ support was required in 11/22 (50%), 5/22 (22%) required only vasopressor support, 2/22 (9%) required only invasive ventilation, and 4/22 (18%) were admitted for monitoring. Patients were ventilated using protective lung strategies, and fluid management was conservative. Standard vasopressors were used, indications for renal replacement therapy were conventional, and blood product usage was restrictive; 9/22 (41%) received corticosteroids. One patient with QTT died, and two (8%) additional patients with QTT developed purpura fulminans requiring digital amputation. Death or permanent disability occurred in 3/9 (33%) QTT and 0/13 scrub typhus cases (P = 0.055). Queensland tick typhus and scrub typhus can cause multi-organ failure requiring ICU care in otherwise well individuals. Queensland tick typhus appears to have a more severe clinical phenotype than previously believed.

The present study examined hospital-based serological tests of rickettsial infections and assessment for diagnosis of pyrexia of unknown origin (PUO). Blood samples were tested for Weil Felix antigens, ELISA for scrub typhus group and polymerase chain reaction (PCR) to detect the presence of DNA of spotted and scrub typhus group with the help of specific oligonucleotide. We tested 450 patient samples and found 101 Weil Felix-positive with 15 having ≥320 titres. IgM ELISA identified 32 (7.1%) positive cases. Positive PCR was seen in 13 (2.9%) samples, being only 40.1% of those testing positive for ELISA. Rickettsial infection is predominantly diagnosed through serological evidence in combination with molecular techniques. The Weil Felix test has a number of disadvantages and tends to provide false-positive results in a number of scenarios, especially where scrub typhus and spotted fever are widely distributed.

Japanese spotted fever (JSF) is an uncommon but potentially fatal infection transmitted by tick bites. We herein report a fulminant case of JSF infection that occurred in an immunocompetent adult that was complicated by disseminated intravascular coagulation and hemophagocytic lymphohistiocytosis (HLH). We discuss the difficulty in making the diagnosis and identifying the complication of HLH in our patient. HLH is a rare complication of rickettsiosis, and this is the first reported case in English of JSF complicated by HLH in an immunocompetent adult. Secondary HLH caused by rickettsiosis requires a different treatment from primary HLH. Rickettsiosis must therefore be considered in patients with HLH.

RATIONALE: Both Borrelia burgdorferi sensu lato and spotted fever group Rickettsiae (SFGR) are pathogens carried by ticks. There is a possibility of co-infection with these tick-borne diseases. PATIENT CONCERNS: Male patient, 63 years-of-age, admitted to hospital with skin rash presenting for 1 week and fever with cough and expectoration for 3 days before admission. DIAGNOSES: We diagnosed that the patient was co-infected by B burgdorferi sl and SFGR using laboratory test results and the patient's clinical manifestations. INTERVENTIONS: The patient started therapy with oral minocycline, then levofloxacin by intravenous injection for SFGR. Meanwhile, he was treated with penicillin G sodium, cefoperazone sulbactam sodium and ceftriaxone by intravenous injection for B burgdorferi sl. OUTCOMES: After the patient was in stable condition, he was discharged from hospital. LESSONS: This case report highlights the possibility of co-infection by 2 tick-borne diseases in Urumqi, Xinjiang Uygur Autonomous Region, China. The antibiotic therapy should be based on the detection of pathogenic bacteria, and the different susceptibilities of co-infecting bacteria should be considered.

We describe the case of a 17-year-old male patient living in Salta city who, 10 days after visiting a rural area in Salta province, was hospitalized for febrile seizures. Shortly after admission, he developed an exanthema followed by a multiple organ dysfunction that evolved to irreversible septic shock followed by death 48 hours after admission. Serological diagnosis -high IgM and IgG anti-Rickettsia spp. antibody titres as detected by indirect immunofluorescence- arrived post mortem. Spotted fever group rickettsioses are tick-borne diseases distributed worldwide and continue being under diagnosed in several countries mainly due to a low clinical suspicion. In the north-western provinces of Argentina there is also the limitation of not counting with a regional laboratory to perform the etiological diagnosis. This is crucial because the severe forms of the disease, which are commonly caused by R. rickettsii, have been already documented in the region. Given that spotted fevers have broadly unspecific febrile presentations and the components of the enzootic cycle are present even in geographic areas not yet considered to be endemic for tick borne diseases, their diagnosis should not be underestimated. If the adequate antibiotic treatment is administered timely, the prognosis of this group of life-threatening diseases improves drastically.

Describimos el caso de un varón de 17 años oriundo de la ciudad de Salta quien, 10 días después de visitar una zona rural de la provincia homónima, ingresó a nuestro hospital por convulsiones febriles. Durante la internación presentó exantema seguido de disfunción orgánica múltiple, la que evolucionó rápidamente hacia shock séptico irreversible y muerte a las 48 horas de su admisión. El diagnóstico serológico -altos títulos de IgM e IgG anti-Rickettsia spp. por inmunofluorescencia indirecta- arribó post mortem. Las rickettsiosis del grupo de las fiebres manchadas son transmitidas por garrapatas, tienen distribución global y en varios países continúan siendo subdiagnosticadas debido a una baja sospecha clínica. En las provincias del noroeste argentino se agrega la carencia de un laboratorio regional capacitado para efectuar el diagnóstico etiológico. Esta limitación es crítica porque en esa región del país ya ha sido documentada la presencia de las formas graves de la enfermedad, usualmente debidas a R. rickettsii. Dado que las fiebres manchadas se presentan como sindromes febriles inespecíficos y los componentes del ciclo enzoótico están presentes en vastas áreas geográficas, incluso en algunas aún no consideradas endémicas para rickettsiosis, su diagnóstico nunca debe ser subestimado. Con el tratamiento antibiótico adecuado instaurado en tiempo oportuno, el pronóstico de este grupo de enfermedades potencialmente mortales mejora en forma drástica.

We report a series of 5 case-patients who had Israeli spotted fever, of whom 2 had purpura fulminans and died. Four case-patients were given a diagnosis on the basis of PCR of skin biopsy specimens 3-4 days after treatment with doxycycline; 1 case-patient was given a diagnosis on the basis of seroconversion. Rickettsia spp. from the 2 case-patients who died were sequenced and identified as Rickettsia conorii subsp. israelensis. Purpura fulminans has been described in association with R. rickettsii and R. indica, but rarely with R. conorii subsp. israelensis.

Rickettsia slovaca, a spotted fever group rickettsial pathogen, causes a syndrome consisting of scalp eschar and neck lymphadenopathy following tick bite. We analyzed the histologic skin reaction in the eschar, showing a prominent eosinophilic infiltration, as well as the presence of B lymphocytes and CD4- and CD8-positive T cells. Examination of the serum cytokine responses over time demonstrated an initial proinflammatory cytokine elevation followed by normalization.

BACKGROUND: African tick-bite fever is an increasingly common cause for fever in the returning traveller. It needs to be considered in the febrile returning traveller with a characteristic rash: a black eschar. CASE REPORT: We describe a 51-year-old man returning from South Africa who presented to our emergency department with fever, headache, myalgia, and chills. On careful history and skin examination, a black eschar was found on the patient's left lateral shoulder, pointing toward a diagnosis of African tick-bite fever. The patient was treated with doxycycline and rapidly improved. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: In the emergency department, the diagnosis of African tick-bite fever is often overlooked in the pursuit of ruling out other travel-related illnesses, such as malaria. A thorough history, a complete physical examination, and a high level of suspicion are essential to the timely diagnosis and treatment of African tick-bite fever in the returning traveller.

Acute febrile illness is a common entity in tropics and often is challenging due a host of pathogenic bacteria, viruses and fungi. Extensive work up is required for better management. Rickettsiosis is uncommon and hence comes lower down in the differentials of multiorgan failure being superseded by the more common diseases as malaria, enteric fever and Dengue. We document a case of young male presenting with high grade fever, multiorgan dysfunction (hepatic, renal, neurological and respiratory involvement), conjunctival suffusion, retiform rash and without lymphadenopathy. The diagnosis was further challenging because the rashes appeared late at 8th day in the course of illness, unlike the typical disease where rashes come on early in day 3-6 of the disease. Patient responded to timely treatment with doxycycline. Thus, a high index of suspicion is needed to diagnose Rickettsiosis in geographical areas apparently free of the disease.
