Dengue and malaria coinfection in a traveling patient: Case study

Introduction: Dengue and malaria are two prevalent diseases in the tropics, transmitted by vectors, and cause different morbidity and fatality rates. However, coinfection of dengue and malaria is relatively rare but clinically significant, since both diseases can have severe manifestations and their coexistence complicate diagnosis and treatment. Clinical Case: The clinical case of a male patient, 32 years old, resident in Angola, who entered Ecuador twenty-one days prior to the onset of symptoms, with no history, was hospitalized for unquantified temperature rise, myalgia, arthralgia and fatigue. His clinical picture is exacerbated with abdominal pain in the right upper quadrant and generalized rash, BP: 105/58 mmHg, HR: 108 bpm, RR: 18 rpm, pulse oximetry 98%, T°: 38°C, dry oral mucosa, expansibility of the decreased chest, dysrhythmic heart, no murmurs, painful abdomen, absent fluid sounds, extremities without edema. The rapid antigen test performed was positive for Plasmodium falciparum, thick smear positive for Plasmodium falciparum. Discussion: The simultaneous treatment of malaria and dengue required careful monitoring of warning signs and possible complications; collaboration between health professionals from Ecuador and Angola was necessary for the successful management and handling of the patient.Conclusions: Documentation of such cases should influence health policies and the planning of preventive strategies, such as vaccination, vector control, and preventive education of travelers before visiting endemic areas.

Malaria and typhoid fever co-infection: disease severity and immune response

Malaria and typhoid fever co-infection: disease severity and immune response

Possible alteration in serum ferritin level in malaria infected HIV seropositive individuals in Nauth, Nnewi, Nigeria

The role of Ferritin in monitoring disease progression in immune compromised HIV individuals with an underlying active infection like malaria is a subject of growing research. Ferritin being an acute phase protein, plays important role in assessing the range of damage due to inflammation in immunosuppressed patients leaving in highly endemic malaria regions. The levels of serum ferritin in malaria infected HIV positive individuals in Nnamdi Azikiwe University teaching hospital (NAUTH), Nnewi, Anambra State, Nigeria, was assessed. Questionnaire was used to obtain the demographic details of the participants, and to rule out other inflammatory infections. 88 participants of the age group 18 - 65 years, comprising 24 with HIV infection, 22 with HIV and Malaria co-infection, 22 with Malaria infection, and a control group of 22 individuals with neither HIV nor malaria infection were randomly recruited. Ferritin level was determined using enzyme linked immunosorbent assay technique and a cross sectional prospective study design was used. A significantly high mean serum ferritin level was observed in HIV infected individuals with and/ or without malaria co-infection than in malaria positive and control group (p<0.05 respectively). Serum ferritin level was significantly higher in female participants than in male counterparts (p < 0.05). Serum ferritin level was significantly higher in individuals with CD4 count >500 than in CD4 count ≤ 500 (p < 0.05). Blood pressure was significantly higher in HIV infected and malaria positive individuals when compared with controls. The increased serum ferritin level and higher blood pressure in HIV infected participants suggests active inflammatory process, reduced immunity and hypertension which may have worsened by malaria co-infection. This may subsequently lead to vascular and endothelia damage causing disease severity.

Malaria and typhoid fever co-infection: a retrospective analysis of University Hospital records in Nigeria

BackgroundStudies have long documented the presence of malaria and typhoid fever in sub-Saharan Africa (SSA). However, studies on these diseases have primarily concentrated on rural settings, neglecting the potential impact on urban areas. This knowledge gap hinders effective surveillance and intervention strategies. To bridge this gap, this study investigated the prevalence of malaria and typhoid co-infections in an urban environment.MethodsThis study, conducted at Lead City University Hospital in Ibadan, Nigeria (West Africa’s largest metropolis), analysed medical records of over 3195 patients seen between April and June 2023. Descriptive statistics and chi-square tests were used to understand how these co-infections were distributed across different age and gender groups.ResultsThe prevalence of co-infection peaked in May (9.7%), followed by June (8.9%) and April (5.7%). Notably, children aged 6–12 years exhibited the highest co-infection rate (18.5%), while those under five had the lowest (6.3%). Gender analysis indicated a slight difference, with 8.8% of females and 7.1% of males co-infected. Malaria prevalence was highest at the beginning of the rainy season and significantly decreased over time. Conversely, typhoid fever displayed the opposite trend, increasing with the rainy season. Children under five years old were most susceptible to malaria, while typhoid fever predominantly affected adults over 25 years old, with prevalence decreasing significantly with age.ConclusionThis study sheds light on the previously overlooked risk of malaria and typhoid co-infections in urban settings. These findings highlight the need for enhanced surveillance and targeted public health interventions, particularly for vulnerable groups like young children during peak transmission seasons.

Assessment of bidirectional impact of stigmatization induced self-medication on COVID-19 and malaria transmissions using mathematical modeling: Nigeria as a case study

The continual social and economic impact of infectious diseases on nations has maintained sustained attention on their control and treatment, of which self-medication has been one of the means employed by some individuals. Self-medication complicates the attempt of their control and treatment as it conflicts with some of the measures implemented by health authorities. Added to these complications is the stigmatization of individuals with some diseases in some jurisdictions. This study investigates the co-infection of COVID-19 and malaria and its related deaths and further highlights how self-medication and stigmatization add to the complexities of the fight against these two diseases using Nigeria as a study case. Using a mathematical model on COVID-19 and malaria co-infection, we address the question: to what degree does the impact of the interaction between COVID-19 and malaria amplify infections and deaths induced by both diseases via self-medication and stigmatization? We demonstrate that COVID-19 related self-medication due to misdiagnoses contributes substantially to the prevalence of disease. The control reproduction numbers for these diseases and quantification of model parameters uncertainties and sensitivities are presented.

Malaria and Typhoid Fever Coinfection among Febrile Patients Attending Kafin-Maiyaki Primary Health Centre

Study’s Novelty/Excerpt This study investigates the burden and co-existence of malaria and typhoid fever among febrile patients, providing a rare examination of these symptomatically similar but aetiologically distinct diseases in a single patient cohort. The novelty of the research lies in its detailed analysis of co-infection rates across different age groups and genders, highlighting significant age-related disparities and suggesting the higher vulnerability of older patients. These findings underscore the importance of concurrent screening for malaria and typhoid fever in febrile patients, offering critical insights for improving diagnostic and treatment strategies in the study area. Full Abstract Malaria and typhoid fever are two symptomatically similar but aetiologically dissimilar diseases: mala ria is caused by parasitic agents from Plasmodium species; ty phoid fever, on the other hand, is caused by Salmonella typhi. They both have no gender distinction in terms of their effect, but malaria appears to be more severe among children. The study aimed to determine the burden of these two diseases among febrile patients in the study area by collecting four (4) mL of blood from each participant, 2 mL of which were dispensed into EDTA bottles for use to detect microscopic parasites. The harvested serum from the remainder was used for the Widal agglutination test to detect the presence of antibodies to Salmonella species. Based on the results, malaria and typhoid fever co-existence was found to be 20.9%. The findings with respect to age group revealed that patients >60 years had a higher coinfection rate of 75% while the 1-12 years age group had the least coinfection (10.6%). There was a significant association between coinfection and age groups (p = 0.019). With respect to gender, females were more prone to be co-infected (53.6%) compared to their male counterparts (46.4%) out of the total positive cases (28) obtained, but the observed difference was not statistically significant (p = 0.016). We therefore recommend concurrent screening of these diseases in all febrile cases in the study area.

Malaria and Typhoid Co-Infection among Children under 5 Years of Age at Chukwuemeka Odumegwu Ojukwu University Teaching Hospital, Awka, Anambra State, Nigeria

This study sheds light on the prevalence of malaria and typhoid in children below the age of five in a hospital in Nigeria. This study aimed to determine the presence of malaria, typhoid and malaria-typhoid co-infection in children less than five years of age. In this community-based descriptive, quantitative and cross-sectional hospital-based survey, the blood samples of 125 children between 0 to less than 5 years (68 males and 57 females) were examined for the presence of malaria parasites and typhoid infection. Blood samples were collected using venepuncture. The malaria parasitaemia was detected using malaria microscopy on a thick blood film. Typhoid fever infection was detected using the Widal Agglutination Test. The chi-square test was used to compare the prevalence of malaria, typhoid fever and malaria/typhoid co-infections between male and female infected and uninfected participants and between children below 1 year and those 1 year and above. P-values less than 0.05 were considered significant. A prevalence of 47.2%, 32% and 16% were recorded for malaria, typhoid and malaria/typhoid co-infection respectively. A mean malaria parasite intensity of 56.8475 (±3.30177) was recorded. There was no significant difference between the prevalence of malaria, typhoid and malaria/typhoid co-infection between the genders and age groups. Also, there was no significant difference between the mean PCV of the infected (33.1610 (±0.80748) and uninfected (34.6667 (0.48441) (P> 0.05). These results underscore the importance of continued efforts to combat these diseases and improve the health and well-being of children in the region.

Optimal control and cost effectiveness analysis of a Zika–Malaria co-infection model

Malaria and Zika, are two significant public health concerns, particularly in tropical and subtropical regions. The co-infection of Malaria and Zika can occur due to overlapping geographical distributions of their respective vectors, namely Anopheles mosquitoes for Malaria and Aedes mosquitoes for Zika. These mosquitoes serve as intermediate hosts for the parasites and viruses, respectively. The proposed mathematical models capture the complex interactions between the human population and the mosquito population to provide insights into the transmission dynamics. The primary transmission route to humans is through the bite of infected mosquitoes for both diseases. Moreover, Zika virus can be also transmitted sexually and vertically. The models provide a valuable tool for evaluating the impact of different interventions on the transmission dynamics of Malaria and Zika co-infection such as prevention schemes against co-infection with Malaria and Zika, prompt Malaria treatment, and effective mosquito control measures. Using Pontryagin’s maximum principle, the model determines the most effective strategies for reducing Malaria and Zika co-infection over time. By combining modeling with cost-effectiveness analysis and targeted interventions, it is possible to develop evidence-based approaches that reduce disease transmission, protect vulnerable populations, and make efficient use of available resources.

Helminthiasis and malaria co-infection among women of reproductive age in a rural setting of Kilifi County, coastal Kenya: A mixed method study.

Soil transmitted helminthiasis (STH), Schistosoma haematobium and malaria co-infection lead to increased susceptibility to other infections and poor pregnancy outcomes among women of reproductive age (WRA). This study sought to establish risk factors, burden of co-infection with STH, S. haematobium and Plasmodium sp. among WRA in Kilifi County, Kenya.A mixed method cross-sectional study was conducted on 474 WRA in 2021. Simple random sampling was used to select WRA from four villages in two purposively sampled sub-counties. Study participants were interviewed, and stool samples collected and analysed using Kato-Katz technique for STH. Urine samples were collected for examination of S. haematobium while malaria microscopic test was done using finger prick blood samples. Further, 15 focus group discussions (FGDs) were conducted with purposively selected WRA and qualitative data analyzed thematically using Nvivo software. Quantitative and qualitative methods were triangulated to comprehensively strengthen the study findings. Prevalence of S. haematobium was 22.3% (95%CI: 13.5-36.9), any STH 5.2% (95%CI: 1.9-14.3) and malaria 8.3% (95%: 3.8-18.2). Co-infections between any STH and S. haematobium was 0.8% (95%CI: 0.2-3.2) and between S. haematobium and malaria 0.8% (95%CI: 0.2-3.1). Multivariable analysis showed increased odds of any STH infections among participants in Rabai Sub-County, (aOR = 9.74; p = 0.026), businesswomen (aOR = 5.25; p<0.001), housewives (aOR = 2.78; p = 0.003), and casual laborers (aOR = 27.03; p<0.001). Qualitative analysis showed that the three parasitic diseases were common and responsible for possible causes of low birth weight, susceptibility to other infections and complications such as infertility and cancer later in life.The study demonstrated that STH, S. haematobium and malaria are still a public health problem to WRA. Some of the associated risks of infection were geographical location, socio-economic and WASH factors. Hence the need to implement integrated control efforts of the three parasitic infection.

Soil-Transmitted Helminthiasis, Intestinal Schistosomiasis and Malaria Co-Infections among Children in Rural Communities Around Rwasave and Cyarwa Valleys

Background: Soil-transmitted helminthiasis, schistosomiasis and malaria remain a threat in developing countries, especially to people living in rural areas near large water bodies, valleys or swamps whose daily life activities revolve around those areas. In addition, these parasites affect different groups of people especially those in contact with their breeding sites including children mostly due to their developing immunity compared to that of old people. Methodology: This cross-sectional study was conducted in rural communities near the Rwasave and Cyarwa valleys, with 124 school-aged children participating. Stool samples were tested for the presence of STH eggs and intestinal Schistosoma parasites using the Kato Katz technique, and thick blood smears were made to aid in the identification of plasmodium species in blood. The threshold intensity of infection on STHs and Schistosoma sp. was estimated by counting their eggs microscopically, which aided in classifying infections as light, moderate, or heavy according to WHO standards. Furthermore, Plasmodium species were identified by the presence of schizonts, trophozoites, or gametocytes on Giemsa-stained thick blood smears, and parasitic density was calculated as a result. Results: In this study, the highest prevalence of soil transmitted helminthiasis was 12.7% in Cyarwa valley compared to 12.5% in Rwasave valley. The highest prevalence of Schistosomiasis was 3.2% in Cyarwa valley compared to 1.3% in Rwasave valley. Prevalence of malaria in Cyarwa valley was 3.3% in 63 children. Where children infected were only males falling in 5-8 age group. Conclusion: Results showed high prevalence of soil transmitted helminthiasis which was 12.7% in Cyarwa compared to 12.5% in Rwasave valley especially in children aged 5-8, this due to poor sanitation (P&lt;0.001) that have assessed. Surprisingly, Cyarwa valley is located nearby town. Whereas malaria, intestinal schistosomiasis was low and there were not significantly associated with their risk factors with p-values 0.4, 0.092 respectively which can show that, preventive measures that have been established by government of Rwanda have positive impacts. Furthermore, there was a low prevalence of soil transmitted helminthiasis, intestinal schistosomiasis and malaria co-infection. Keywords: soil transmitted helminthiasis, intestinal schistosomiasis, malaria.

Modelling the co-infection of malaria and zika virus disease

In this work, a new model for the co-infection of malaria and zika virus disease incorporating vaccination, treatment and vector control using sterile-insect technology (SIT) is formulated. The importance of this study is to highlight the possibility of the co-infection of humans with malaria and zika virus disease in any environment where both diseases co-circulate. Also, to suggest a new and comprehensive method for controlling the individual diseases and their co-infection. Through stability analysis, we showed that the disease-free equilibrium, (DFE) point of the co-infection model is locally asymptotically stable when the basic reproduction numbers, Rmz is less than one, and unstable otherwise. But, the DFE failed to be globally stable when Rmz &lt; 1 which is an indication of existence of backward bifurcation in the model. This shows that bringing down the reproduction number, Rmz to less than one is not enough to eradicate the co-infection of the two diseases. Furthermore, it is shown that the two diseases have positive impact on the spread of each other, which could be attributed to misdiagnoses of one disease as the other. We also showed that effective treatment of infectious humans, increasing the rate of vaccination and employing sterile-insect technique to control the vectors significantly helped to control the individual diseases as well as the co-infection. From the results obtained in the study, it can be concluded that effective control of malaria and zika virus disease requires measures that will control their spread in both human and mosquito populations.

Assessment of the selected hematological profiles among malaria and Schistosoma mansoni co-infected patients, Northwest Ethiopia.

Malaria and schistosomiasis are infectious diseases that cause hematological profiles abnormalities. Malaria and Schistosoma mansoni co-infection causes exacerbation of health consequences and co-morbidities. The aim of this study was to assess the selected hematological profiles among malaria and S. mansoni co-infected patients at Dembiya Selected Health Institutions. An institutional-based comparative cross-sectional study was conducted from March 30 to August 10, 2022. A total of 140 individuals were enrolled in the study using a convenient sampling technique. Wet mount and Kato Katz technique were conducted to detect S. mansoni in Stool sample. Blood films were prepared for the detection of plasmodium. The data was coded and entered into EpiData version 3.1 before being analyzed with SPSS version 25. A P-value of less than 0.05 was considered statistically significant. Mean of WBC, neutrophil, lymphocyte, eosinophil, RBC, hemoglobin, and hematocrit [4.IU/L,2.2IU/L, 1.4IU/L, 0.1IU/L, 3.13IU/L, 9.5g/dL, and 28.7%, resepectively] in co-infected were significantly lower than [7.5IU/L, 4.6IU/L, 2.1IU/L, 0.38IU/L, 4.8IU/L, 14.6g/dL, and 43.7%, resepectively] in the healthy control participants. Mean of RBC, hemoglobin, and hematocrit [3.13IU/L, 9.5g/dL, 28.7%, resepectively] in co-infected were significantly lower compared to [3.8IU/L, 11.5g/dL, 33.9%, resepectively] in the malaria monoinfected participants and [3.7IU/L,11.5g/dL, 33.6%, resepectively] in the S. mansoni monoinfected participants. The result of hematological profiles in healthy participants had no significant difference compared to light,moderate and heavy S. mansoni infection intensity in coinfection. The number of S. mansoni eggs per gram of stool had been negatively correlated with hematological profiles of co-infected participants except lymphocyte and monocyte which correlated positively. Hematological profiles status in coinfection were significantly altered compared to malaria monoinfection, S. mansoni monoinfection, and healthy participants.Therefore, hematological tests should be used to monitor and manage coinfection related complications, and to reduce coinfection associated morbidity and mortality.

Prevalence of Malaria and Helicobacter Pylori Coinfection and Associated Sociodemographic Factors among Blood Donors in Douala General Hospital

Background: The malaria parasite Plasmodium is intra-erythrocyte hence can be transmitted by transfusion of any blood component containing infected red blood cells. Helicobacter pylori infection affects more than half of the human population worldwide. Infection remains asymptomatic in most individuals, although some individuals develop acute gastritis, peptic or duodenal ulcers, gastric cancer, and mucosa associated tissue lymphoma. H. pylori infection have been implicated in some haematological manifestations such as anaemia and micronutrient deficiency. Objective: This research was designed to determine the prevalence of malaria parasitaemia and H. pylori coinfection in association with sociodemographic characteristics among donors in Douala General Hospital. Methodology: The study was a hospital-based study carried out from January to May 2022. The study population comprised of 106 donors who came to the hospital laboratory for blood donation. A structured questionnaire was used to get demographic and clinical data. Two ml of blood was collected from individuals to prepare a thick and thin blood film for malaria parasite determination and to centrifuge at 3000 rpm for 5 minutes to obtain plasma for H. pylori test strip. Results and Discussion: The overall prevalence of H. pylori in the study area was 70.8%. The female donors had a prevalence of 72.0%. A greater proportion of blood group O donors had H. pylori than groups A, AB and B but this difference was not significant (P-value = 0.571). The prevalence of malaria parasites infection was 36.8%. Those of blood group A had a higher prevalence rate of 42.3% (11/26). Out of the 106 donors, 23 (21.7%) had malaria and H. pylori coinfection. 68 (64.2%) donors had a mono-infection that is either having malaria mono-infection or H. pylori mono-infection and 15 (14.2%) had no infection. Malaria and H. pylori coinfection was higher in female donors than males (OR = 1.059, 95% Cl 0.359 -3.119, P =0.917), in donors aged below 25 years old (OR = 0.338, 95% Cl 0.075 - 1.535, P =0.160), replacement donors (OR = 1.350, 95% Cl 0.460 – 3.964, P =0.585); blood donors of blood group AB (OR = 0.654, 95% Cl 0.181 – 2.366, P =0.517) and Rhesus negative donors (OR = 1.500, 95% Cl 0.130 – 17.36, P =0.746). Conclusion: The prevalence of H. pylori infection and Malaria among blood donors in Douala General Hospital were high and coinfection was higher in females than males. Both malaria parasites and H. pylori infections have been implicated in blood parameters such as anaemia and micronutrient deficiency. It is therefore recommended that routine screening for malaria parasites and H. pylori be done in blood banks before transfusion for a high blood quality.

Case Report: Managing the Coinfection of Cerebral Malaria and Dengue in the Intensive Care Unit

Background: Dengue and malaria are the two most common arthropod-borne illnesses, but cases of multiple infections are extremely uncommon. The mortality rate for individuals with dengue and malaria was higher than the death rate for those with malaria alone.Case: An intubated 53-year-old male was referred from a class B hospital because of severe malaria with suspected cerebral malaria, dengue fever (day-11), septic shock and acute kidney injury. His initial laboratory investigation showed increasing pattern of WBC, thrombocyte, anemia, peripheral blood smear normochromic normocytic erythrocyte, poikilocytosis (ovalocytes (+), teardrop cells (+)), normoblasts (+), presence of Plasmodium malariae trophozoite and schizont stage parasites, positive result of IgM and IgG anti dengue, increased liver function test, increased BUN and creatinine serum levels, hyperbilirubinemia, hypoalbuminemia, and normal result of blood gas analysis. On the sixth day of ICU admission, the patient gradually regained consciousness with appropriate responsiveness and showed clinical improvement. The patient was discharged after one month of hospital care with the last peripheral blood smear showing no parasites detected.Discussion: Mono-infection with malaria and dengue, two mosquito-borne diseases endemic to tropical and subtropical regions, often carries a high risk of fatality. The risk becomes even more pronounced when co-infection occurs. The early diagnosis and management in the ICU are crucial for cases of coinfection involving cerebral malaria and dengue. The primary focus is on both definitive and supportive therapies.Conclusion: The prognosis for coinfection of cerebral malaria and dengue is generally poor, but in this case, the patient showed improvement and was able to be discharged without any sequelae.

Frequency of Dengue and Malaria Co-Infection in Patients Admitted in Jinnah Hospital, Lahore

Prevalence of malaria and dengue infection coexistence is increasing during endemic periods although causing quite similar symptoms and signs, the treatment of these two illnesses is different. Any suspicion of malaria in disease-endemic areas must be excluded with microscopy and/or rapid antigen test. Objective: To find out the incidence of co-infection of dengue and malaria based on clinical and hematological parameters in patients presenting with acute febrile illness. Methods: This cross-sectional study was done in the Medicine Unit of Jinnah hospital, Lahore from October - December 2022. 140 diagnosed as dengue fever by Non-Structural Protein 1 (NS1) and IgM were included in the study. All the cases were subject to a thorough medical examination i.e. complete battery summary of temperature together with the serology of Dengue, X-ray of the chest, abdominal ultrasound scan, renal function test (RFT), liver function test (LFT), malarial parasite slide, complete blood count with peripheral smear etc. Accordingly, the treatment was given to them with follow-up medical evaluation including detailed investigations. Data were entered and analyzed in SPSS version. 27.0 and presented as frequency and percentages. Chi square test was used to assess statistical significance with P &lt; .05. Results: Mean age of respondent was 35.5 + 15.6 years. Co-infection rate with malaria and severe disease along with prolong duration fever and persistent thrombocytopenia among subjects was15.0%. Conclusions: Majority of co infected individuals were having severe disease, with subsequent development of disseminated intravascular coagulation and sepsis, responding well to anti-malarial treatments

Assessment of Culicidae collection methods for xenomonitoring lymphatic filariasis in malaria co-infection context in Burkina Faso.

Entomological surveillance of lymphatic filariasis and malaria infections play an important role in the decision-making of national programs to control, or eliminate these both diseases. In areas where both diseases prevalence is low, a large number of mosquitoes need to be sampled to determine vectors infection rate. To do this, efficient mosquito collection methods must be used. This study is part in this framework, to assess appropriate mosquito collection methods for lymphatic filariasis xenomonitoring in a coexistence context with malaria in Burkina Faso. Mosquito collections were performed between August and September 2018 in four villages (Koulpissi, Seiga, and Péribgan, Saptan), distributed in East and South-West health regions of Burkina Faso. Different collection methods were used: Human Landing Catches (HLC) executed indoor and outdoor, Window Exit-Trap, Double Net Trap (DNT) and Pyrethrum Spray Catches (PSC). Molecular analyses were performed to identify Anopheles gambiae s.l. sibling species and to detect Wuchereria bancrofti and Plasmodium falciparum infection in Anopheles mosquitoes. A total of 3 322 mosquitoes were collected among this, Anopheles gambiae s.l. was the vector caught in largest proportion (63.82%). An. gambiae s.l. sibling species molecular characterization showed that An. gambiae was the dominant specie in all villages. The Human Landing Catches (indoor and outdoor) collected the highest proportion of mosquitoes (between 61.5% and 82.79%). For the sampling vectors infected to W. bancrofti or P. falciparum, PSC, HLC and Window Exit-Trap were found the most effective collection methods. This study revealed that HLC indoor and outdoor remained the most effective collection method. Likewise, the results showed the probability to use Window Exit-Trap and PSC collection methods to sample Anopheles infected.

Co-infections of malaria and hepatitis B among pregnant women in Igbo-Eze North LGA of Enugu State, Nigeria

Acute hepatitis B virus (HBV) and malaria infections pose serious health risks to the general population and may worsen victims' physical and financial well-being. The objective of this study was to determine the frequency of HBV and malaria co-infections during LGA among expectant mothers. This study used a cross-sectional, prospective design. Blood samples were collected from both pregnant and non-pregnant women for parasitological and serological examinations in the study area. This was performed to compare the severity of infections between pregnant and non- pregnant women, as pregnant women are more susceptible to infections. The study included 50 women who attended antenatal care at the time of this project and 10 non-pregnant women who came to the hospitals for check-ups. Samples of people aged 18 to 52 years were collected. Age groups of 18-28 and 40-50 years had the greatest 30(50%) and lowest 8(13%) populations of women screened for malaria and hepatitis B co-infection, respectively. The 1st and 3rd trimesters were followed by the 2nd trimester, which had the highest prevalence. Only the second trimester had a 2% prevalence rate of hepatitis B. Farmers were the group most likely to contract malaria (92%). The percentage of government employees who had malaria and hepatitis B was the highest 20%), followed by traders (5%). Ogrute, the seat of the Local Government had a high rate of malaria infection despite having several medical facilities and less farming activities. Olido (25%), followed by Ogrute (14 point 3%), had the highest rate of co-infection with hepatitis B and malaria. The PCV ranges of 25–27(100%) and 28–30(100%) had the highest prevalence of malaria. This study shows how persistent malaria and hepatitis B are also associated with decreased packed cell volume (PCV) in pregnant women.

Effect of Malaria and Schistosoma mansoni Coinfection on Selected Biochemical Profiles among Patients Attending Selected Health Institutions at Dembiya, Northwest Ethiopia.

Malaria and schistosomiasis are infectious diseases that cause biochemical abnormalities. Malaria and Schistosoma mansoni coinfection causes exacerbations of health consequences and comorbidities. The study area is found in Ethiopia, where coinfection of malaria and S. mansoni is common. However, there is limited data on the biochemical profiles of patients coinfected with malaria and S. mansoni schistosomiasis in the study area. Hence, this study aimed to assess the effect of malaria and S. mansoni schistosomiasis coinfection on selected biochemical profiles. An institutional-based comparative cross-sectional study was conducted from March 30 to August 10, 2022. Using a convenient sampling technique, 70 participants (35 cases and 35 controls) were enrolled in the study. Schistosoma mansoni was detected in stool samples using the wet mount and the Kato Katz method. To detect Plasmodium, both thick and thin blood films were prepared and stained with Giemsa. The blood sample was processed for the analysis of biochemical profiles. All data were analyzed using SPSS version 25. A p value of less than 0.05 was considered statistically significant. The mean values of alanine aminotransferase and aspartate aminotransferase (37.1 U/L and 41.9 U/L, respectively) in coinfected participants were significantly higher than in the healthy control participants (17.4 U/L and 22.0 U/L, respectively) (p < 0.05). Also, the median values of creatinine, total bilirubin, and direct bilirubin (1.51 mg/dL, 2.35 mg/dL, and 0.91 mg/dL, respectively) in coinfected participants were significantly higher than in the healthy control participants (0.85 mg/dL, 0.42 mg/dL, and 0.12 mg/dL, respectively) (p < 0.05). However, median values of total protein (4.82 g/dL) and mean values of glucose (66.6 mg/dL) in coinfected participants were significantly lower than in the healthy control participants (total protein (7.64 g/dL) and glucose (91.9 mg/dL)) (p < 0.05). The results of biochemical profiles in healthy participants were significantly different from those with light, moderate, and heavy S. mansoni infection intensity in malaria and S. mansoni coinfection (p < 0.05). Schistosoma mansoni infection intensity had a positive correlation with biochemical profiles except for total protein and glucose, which correlated negatively in coinfected participants (p > 0.05). Biochemical profiles in coinfection were significantly changed as compared to healthy individuals. As a result, biochemical profile tests should be utilized to monitor and manage coinfection-related problems, as well as to reduce coinfection-related morbidity and death.

Status of selected biochemical and coagulation profiles and platelet count in malaria and malaria-Schistosoma mansoni co-infection among patients attending at Dembiya selected Health Institutions, Northwest Ethiopia

Malaria and schistosomiasis are infectious diseases that cause coagulation disorders, biochemical abnormalities, and thrombocytopenia. Malaria and Schistosoma mansoni co-infection cause exacerbations of health consequences and co-morbidities.This study aimed to compare the effect of malaria and Schistosoma mansoni co-infection and malaria infection on selected biochemical and coagulation profiles, and platelet count. An institutional-based comparative cross-sectional study was conducted from March 30 to August 10, 2022. A total of 70 individuals were enrolled in the study using a convenient sampling technique. Wet mount and Kato Katz techniques were conducted to detect Schistosoma mansoni in a stool sample. Blood films were prepared for the detection of plasmodium. The data was coded and entered into EpiData version 3.1 before being analyzed with SPSS version 25. An independent t test was used during data analysis. A P-value of less than 0.05 was considered statistically significant. The mean [SD] of alanine aminotransferase, aspartate aminotransferase, creatinine, total bilirubin, and direct bilirubin in the co-infected was higher than in malaria infected participants. However, the mean of total protein and glucose in co-infected was lower than in the malaria infected participants. The mean of prothrombin time, international normalization ratio, and activated partial thromboplastin time in co-infected was significantly higher, while the platelet count was lower compared to malaria infected participants. Biochemical and coagulation profiles, and platelet count status in co-infection were changed compared to malaria infected participants. Therefore, biochemical and coagulation profiles and platelet count tests should be used to monitor and manage co-infection related complications and to reduce co-infection associated morbidity and mortality.
