Hyperglycemia and elevated C-reactive protein are independent predictors of hospital mortality in hospitalized COVID-19 patients in South-Kivu, eastern Democratic Republic of the Congo: A cross-sectional study.

Background and Aim: The coronavirus disease 2019 (COVID-19) pandemic was a priority public health problem because of its high mortality rate. This study mainly aimed to determine factors associated with a poor outcome in COVID-19 hospitalized patients in South-Kivu, an eastern province of the Democratic Republic of the Congo (DRC). Methods: This observational study retrospectively evaluated medical records of patients consecutively admitted for probable or confirmed COVID-19 between May 01 and July 31, 2020 at the Hôpital Provincial Général de Référence de Bukavu (HPGRB), a tertiary hospital located in South-Kivu. A binary logistic regression model was performed to determine the predictors of mortality. Results: A total of 157 hospitalized COVID-19 patients aged 57.7 (13.2) years were included in this study. Male gender (69.4%), older age (52.9%), medical history of diabetes (38.2%), and arterial hypertension (35.1%) were the most frequent risk factors. Most patients presented with fever (73.3%), cough (72.6%), and dyspnea (66.2%). Overall, 45.1% of patients died. Intrahospital mortality was significantly associated with advanced age [odds ratio, OR (95% confidence interval, CI) = 2.34 (1.06-5.38)], hypoxemia [OR (95% CI) = 4.67 (2.02-10.77)], hyperglycemia [OR (95% CI) = 2.14 (1.06-4.31)], kidney failure [OR (95% CI) = 2.82 (1.4-5.68)], hyperleukocytosis [OR (95% CI) = 3.33 (1.67-6.66)], and higher C-reactive protein (CRP) levels [OR (95% CI) = 3.93 (1.93-8.01)]. After adjustment for various covariates, only higher CRP levels [OR (95% CI) = 3.23 (1.23-8.5)] and hyperglycemia [OR (95% CI) = 2.5 (1.02-6.11)] at admission were independently associated with mortality. Conclusion: Hyperglycemia and marked inflammatory syndrome were the major predictors of poor outcomes in patients hospitalized for COVID-19 in South-Kivu. These two factors should be quantified at hospital admission to establish the patient's prognosis.

MRI and CT findings in anterior thoracic myelomeningocele associated with scoliosis: A case of an 8-year-old child.

Anterior Thoracic Myelomeningocele is a very rare condition. The diagnosis may be made before or after birth. Association with loss of physiologic curvature of the spine is common. We report the case of an 8-year-old boy with congenital dorsal sinistro-convex scoliosis, which was considered nonspecific and improved slightly after physical therapy. The onset of urinary and fecal incontinence at the age of 8 years led the parents to consult a urologist. MRI of the spinal cord revealed an anterior thoracic heterogeneous cystic lesion extending from the third to the eighth dorsal vertebrae. The heterogeneous cystic mass contained a solid spinal cord-like structure on all sequences. No abnormal enlargement, no torsion of the cauda equina or cerebellar amygdala. No malformation of the posterior fossa. CT scan showed aplasia of the right pedicle of the third thoracic vertebrae (T3) with thoracic scoliosis. The associated anterior thoracic myelomeningocele was the final diagnosis that motivated the transfer of the patient to a specialized neurosurgical center.

[Mauvais contrôle des facteurs de risque cardiovasculaire modifiables chez les patients congolais en phase aiguë et séquellaire d'un accident vasculaire cérébral : Une étude transversale]. / Poor control of modifiable cardiovascular risk factors among Congolese patients in the acute and sequelae phase of stroke : A cross-sectional study.

PURPOSE: To assess the level of the control of the cardiovascular risk factors in patients with a history of stroke in the Democratic Republic of the Congo. METHODS: The level of the control of arterial hypertension, diabetes mellitus, and dyslipidemias was analyzed in two hundred and seventy-four (274) patients followed for stroke. RESULTS: Among 188 patients with a prior diagnosis of arterial hypertension, only 100 (53.2%) were treated, 27 (27.0%) had their blood pressure well controlled [12.3% in acute stroke vs. 46.5% in sequelae phase; p = 0.0002].  Among 42 (71.2%) diabetics treated, 23 (63.9%) had glycaemia levels > 200 mg/dl, 60.0% in acute phase and 83.3% in sequelae phase (p = 0.28). Finally, 87.0% of the patients had a non-HDL-C > 85 mg/dl. CONCLUSIONS: This study shows a poor control of modifiable cardiovascular risk factors in patients with very high cardiovascular risk due to stroke. There is a need for an effective program to combat non-communicable diseases in our environment.

Etiologies and factors associated with mortality in patients with non-traumatic coma in a tertiary hospital in Bukavu, eastern Democratic Republic of the Congo.

Non-traumatic coma (NTC) is a common medical condition often associated with poor outcomes. Identifying underlying causes is crucial for effective management and prognostication, particularly in resource-poor settings. This study aimed to identify the most common causes and prognostic factors of NTC in a tertiary hospital in Bukavu, in the eastern Democratic Republic of the Congo (DRC), using the Glasgow Coma Scale (GCS) as well as other simple and affordable clinical and paraclinical tools. This retrospective observational study included 219 consecutive patients admitted to the intensive care unit of the Provincial General Hospital of Bukavu between January 2016 and December 2018. Sociodemographic, clinical, and laboratory data were also collected. Bivariate and multivariate analyses were performed to identify different causes and factors associated with poor outcomes in these patients. The median age of the patients was 49 (interquartile range [IQR]: 33-61) years, and they were predominantly men (62.8%). The most common causes of NTC were stroke (25.7%), acute metabolic complications of diabetes (21.9%), and primary brain infections (meningoencephalitis, 16.0%; and cerebral malaria, 14.2%). The NTC-related in-hospital mortality rate was 35.2%. A high mortality was significantly and independently associated with a GCS<7 (adjusted odds ratio [OR]: 4.30, 95% confidence interval [CI]: 1.73-10.71), the presence of meningismus at clinical evaluation (adjusted odds ratio [aOR] 3.86, 95%CI: 1.41-10.55), oxygen saturation <90% (aOR 3.99, 95%CI: 1.71-9.28), the consumption of traditional herbal medicines prior to hospital admission (aOR 2.82, 95%CI: 1.16-6.86), and elevated serum creatinine (aOR 1.64, 95%CI: 1.17-2.29). In conclusion, clinical neurological examinations, along with simple and affordable paraclinical investigations, can provide sufficient information to determine the etiology of NTC and evaluate the prognosis of comatose patients, even in resource-poor settings. Physicians may use the GCS as a simple, reliable, and affordable tool to identify patients who require special attention and care.

Psychopathological states among Congolese health workers during the first wave of COVID-19 pandemic: links with emotion regulation and social support.

Background: The COVID-19 pandemic is an unprecedented stressor for frontline healthcare workers, notably increasing acute stress disorder and depression rates. Emotion regulation and social support could be major protective factors against such psychopathological states, but their role has not been explored outside Western contexts. Objective: To assess the association between emotion regulation, social support, acute stress disorder, and depression among healthcare workers directly confronted with the first wave of COVID-19 pandemic in the eastern Democratic Republic of the Congo. Method: A cross-sectional study assessed acute stress disorder, depression, adaptive (i.e. acceptance, positive refocusing, …) and maladaptive (i.e. self-blame, rumination, catastrophizing, …) emotion regulation strategies, social support (instrumental, emotional, and informational levels), as well as self-reported situations and feelings related to COVID-19, in a population of 252 frontline healthcare workers (121 women; 131 men; mean age: 39 ± 11 years old) at the Referral General Hospital of Bukavu. We also explored the relations between these variables through bivariate and multivariate logistic regression. Results: Forty percent of participants presented symptoms of depression, and 16% presented acute stress disorder. In bivariate logistic regression, these psychiatric outcomes were associated with the availability of a COVID-19 protection kit [OR = 0.24 (0.12-0.98)], hostility toward health workers [OR = 3.21 (1.23-4.21)], putting into perspective [OR = 0.91 (0.43-0.98)], self-blame [OR = 1.44 (1.11-2.39)], catastrophizing [OR = 1.85 (1.01-4.28)], blaming others [OR = 1.77 (1.04-3.32)], emotional support [OR = 0.83 (0.49-0.98)], instrumental support [OR = 0.74 (0.28-0.94)], and informational support [OR = 0.73 (0.43-0.98)]. In multivariate logistic regression, hostility [OR = 2.21 (1.54-3.78)], self-blame [OR = 1.57 (1.02-2.11)], rumination [OR = 1.49 (1.11-3.13)] and emotional support [OR = 0.94 (0.65-0.98)] remained significantly associated with psychiatric outcomes. Conclusion: Depression and acute stress disorder were highly prevalent among Congolese healthcare workers during the first wave of the COVID-19 health pandemic. Hostility, self-blame, rumination, and social support were associated with depression and/or acute stress disorder and should be targeted by interventions aiming to support health workers' wellbeing. HIGHLIGHTS: Frontline health workers presented high prevalence of acute stress disorder (16%) and depression (40%) during the first wave of COVID-19 pandemic in the Eastern Democratic Republic of the Congo, as they were working in hostile environment without enough protection kits.Acute stress disorder and depression were negatively associated with adaptive emotion regulation and social support; and positively with maladaptive emotion regulation.Intervention aiming to support health workers in pandemics should target emotion regulation and social support.

Antecedentes: La pandemia de COVID-19 es un factor estresante sin precedentes para los trabajadores de atención médica de primera línea, que aumenta notablemente las tasas de trastorno por estrés agudo y depresión. La regulación de las emociones y el apoyo social podrían ser factores protectores importantes contra tales estados psicopatológicos, pero su papel no ha sido explorado fuera de los contextos occidentales.Objetivo: Evaluar la asociación entre la regulación de las emociones, el apoyo social, el trastorno de estrés agudo y la depresión entre los trabajadores de la salud que confrontaron directamente la primera ola de la pandemia de COVID-19 en el este de la República Democrática del Congo.Método: Un estudio transversal evaluó el trastorno de estrés agudo, la depresión, estrategias de regulación emocional adaptativas (es decir, aceptación, refocalización positiva, …) y desadaptativas (es decir, autoculpabilización, rumiación, catastrofización, …), apoyo social (niveles instrumental, emocional, e informacional), así como situaciones y sentimientos autoinformados relacionados con el COVID-19, en una población de 252 trabajadores de salud de primera línea (121 mujeres; 131 hombres; edad media: 39 ± 11 años) en el Hospital General de Referencia de Bukavu. También exploramos las relaciones entre estas variables mediante regresión logística bivariada y multivariada.Resultados: Cuarenta por ciento de los participantes presentó síntomas de depresión y el dieciséis por ciento presentó trastorno de estrés agudo. En regresión logística bivariada, estos resultados psiquiátricos se asociaron con la disponibilidad de un kit de protección COVID-19 [OR = 0.24 (0.12­0.98)], hostilidad hacia los trabajadores de la salud [OR = 3.21 (1.23­4.21)], postura en perspectiva [ OR = 0.91 (0.43­0.98)], autoculpabilización [OR = 1.44 (1.11­2.39)], catastrofización [OR = 1.85 (1.01­4.28)], heteroculpabilización [OR = 1.77 (1.04­3.32)], apoyo emocional [OR = 0.83 (0.49­0.98)], apoyo instrumental [OR = 0.74 (0.28­0.94)] y apoyo informativo [OR = 0.73 (0.43­0.98)]. En la regresión logística multivariada, hostilidad [OR = 2.21 (1.54­3.78)], autoculpabilización [OR = 1.57 (1.02­2.11)], rumiación [OR = 1.49 (1.11­3.13)] y apoyo emocional [OR = 0.94 (0.65­0.98)] permanecieron significativamente asociados con los resultados psiquiátricos.Conclusión: La depresión y el trastorno de estrés agudo fueron muy frecuentes entre los trabajadores de la salud congoleños durante la primera ola de la pandemia sanitaria de COVID-19. La hostilidad, la autoculpabilización, la rumiación y el apoyo social se asociaron con depresión y/o trastorno de estrés agudo y deberían ser el objetivo de las intervenciones destinadas a apoyar el bienestar de los trabajadores de la salud.

Epilepsia partialis continua associated with ketotic hyperglycemia and tuberculous meningoencephalitis: A case report.

We report the case of an 18-year-old girl who presented with several episodes of simple partial motor seizures compatible with the diagnosis of epilepsia partialis continua. In addition to ketotic hyperglycemia, tuberculous meningoencephalitis was diagnosed based on clinical, biological, and brain imaging findings. The seizures ceased after normalization of glycemia.

Revisiting Konzo Risk Factors in Three Areas Differently Affected by Spastic Paraparesis in Eastern Democratic Republic of the Congo Discloses a Prominent Role of the Nutritional Status-A Comparative Cross-Sectional Study.

This comparative cross-sectional study aimed to better understand the respective contributions of protein malnutrition and cassava-derived cyanide poisoning in the development of konzo. We compared data on nutritional status and cyanide exposure of school-age adolescent konzo-diseased patients to those of non-konzo subjects of similar age from three areas in the Eastern Democratic Republic of the Congo. Our results show that konzo patients had a high prevalence of both wasting (54.5%) and stunting (72.7%), as well as of cyanide poisoning (81.8%). Controls from Burhinyi and those from Idjwi showed a similar profile with a low prevalence of wasting (3.3% and 6.5%, respectively) and intermediate prevalence of stunting (26.7% and 23.9%, respectively). They both had a high prevalence of cyanide poisoning (50.0% and 63.0%, respectively), similar to konzo-patients. On the other hand, controls from Bukavu showed the lowest prevalence of both risk factors, namely chronic malnutrition (12.1%) and cyanide poisoning (27.6%). In conclusion, cassava-derived cyanide poisoning does not necessarily coexist with konzo outbreaks. The only factor differentiating konzo patients from healthy individuals exposed to cyanide poisoning appeared to be their worse nutritional status. This further suggests that, besides the known role of cyanide poisoning in the pathogenesis of konzo, malnutrition may be a key factor for the disease occurrence.

Konzo risk factors, determinants and etiopathogenesis: What is new? A systematic review.

Konzo is a toxico-nutritional upper motor neuron disease causing a spastic paraparesis in schoolchildren and childbearing women in some African countries. Almost a century since the first description of konzo, its underlying etiopathogenic mechanisms and causative agent remain unknown. This paper aims at refreshing the current knowledge of konzo determinants and pathogenesis in order to enlighten potential new research and management perspectives. Literature research was performed in PubMed and Web of Science databases according to the PRISMA methodology. Available data show that cassava-derived cyanide poisoning and protein malnutrition constitute two well-documented risk factors of konzo. However, observational studies have failed to demonstrate the causal relationship between konzo and cyanide poisoning. Thiocyanate, the current marker of choice of cyanide exposure, may underestimate the actual level of cyanide poisoning in konzo patients as a larger amount of cyanide is detoxified via other unusual pathways in the context of protein malnutrition characterizing these patients. Furthermore, the appearance of konzo may be the consequence of the interplay of several factors including cyanide metabolites, nutritional deficiencies, psycho-emotional and geo-environmental factors, resulting in pathophysiologic phenomena such as excitotoxicity or oxidative stress, responsible for neuronal damage that takes place at sparse cellular and/or subcellular levels.

Atypical respiratory distress in eastern Democratic Republic of the Congo prior to the COVID-19 pandemic. A case report.

BACKGROUND: Predictions have been made that Africa would be the most vulnerable continent to the novel Coronavirus disease 2019 (COVID-19). Interestingly, the spread of the disease in Africa seems to have been delayed and initially slower than in many parts of the world. Here we report on two cases of respiratory distress in our region before the official declaration of the disease in December 2019, cases which in the present times would be suspect of COVID-19. CASE PRESENTATION: These two cases (one 55-year-old man and one 25-year-old woman) of acute respiratory distress secondary to atypical pneumonia were seen in Bukavu, in Eastern Democratic Republic of the Congo (DRC), between September and December 2019. One patient had returned from China and the other had close contacts with travellers from China in the 2 weeks prior to the onset of symptoms. In either case, the aetiology could not be accurately determined. However, the two cases presented a clinical picture (progressive dyspnoea, preceded by dry cough and fever) and laboratory changes (procalcitonin within the normal range, slight inflammation, and lymphopenia) compatible with a viral infection. The chest X-ray series of the first patient showed lesions (reticulations, ground glass, and nodules ≤6 mm) similar to those currently found in COVID-19 patients. In addition, unlike the 25-year-old female patient who had no comorbidity, the 55-year-old male patient who had hypertension as comorbidity, developed a more severe acute respiratory distress which progressed to death. CONCLUSION: These cases bring to the attention the fact that COVID-19-like syndromes may have already been present in the region months before the official beginning of the pandemic. This also brings to question whether a prior presence of the disease or infections with related virus may account for the delayed and less extensive development of the pandemic in the region.

A case study of the first pregnant woman with COVID-19 in Bukavu, eastern Democratic Republic of the Congo.

INTRODUCTION: Vertical transmission of covid-19 is possible; its risk factors are worth researching. The placental changes found in pregnant women have a definite impact on the foetus. CASE PRESENTATION: We report a case of a 25-year-old woman, gravida 3, para 2 (2 alive children), with a history of two caesarean deliveries, who was infected by the SARS-CoV-2 during the last term of her pregnancy. She gave birth by caesarean at 34 weeks of gestation to a newborn baby also infected with SARS-CoV-2. The peri-operative observations noted several eruptive lesions in the pelvis, bleeding on contact. Microscopic examination of the foetal appendages revealed thrombotic vasculopathy in the placenta and in the umbilical cord vessels. CONCLUSION: This case is one of the first documented cases of COVID-19 in pregnancy in sub-Saharan Africa. We strongly suggest obstetricians to carefully examine the aspect of the peritoneum, viscera and foetal appendages in affected pregnant women.

Long-term effects of severe acute malnutrition during childhood on adult cognitive, academic and behavioural development in African fragile countries: The Lwiro cohort study in Democratic Republic of the Congo.

INTRODUCTION: Little is known about the outcomes of subjects with a history of severe acute malnutrition (SAM). We therefore sought to explore the long-term effects of SAM during childhood on human capital in adulthood in terms of education, cognition, self-esteem and health-related disabilities in daily living. METHODOLOGY: We traced 524 adults (median age of 22) in the eastern Democratic Republic of the Congo, who were treated for SAM during childhood at Lwiro hospital between 1988 and 2007 (median age 41 months). We compared them with 407 community controls of comparable age and sex. Our outcomes of interest were education, cognitive function [assessed using the Mini Mental State Examination (MMSE) for literate participants, or its modified version created by Ertan et al. (MMSE-I) for uneducated participants], self-esteem (measured using the Rosenberg Self-Esteem Scale) and health-related social and functional disabilities measured using the World Health Organization Disability Assessment Schedule (WHODAS). For comparison, we used the Chi-squared test along with the Student's t-test for the proportions and means respectively. RESULTS: Compared with the community controls, malnutrition survivors had a lower probability of attaining a high level of education (p < 0.001), of reporting a high academic performance (p = 0.014) or of having high self-esteem (p = 0.003). In addition, malnutrition survivors had an overall mean score in the cognitive test that was lower compared with the community controls [25.6 compared with 27.8, p = 0.001 (MMSE) and 22.8 compared with 26.3, p < 0.001(MMSE-I)] and a lower proportion of subjects with a normal result in this test (78.0% compared with 90.1%, p < 0.001). Lastly, in terms of health-related disabilities, unlike the community controls, malnutrition survivors had less social disability (p = 0.034), but no difference was observed as regards activities of daily living (p = 0.322). CONCLUSION: SAM during childhood exposes survivors to low human capital as regards education, cognition and behaviour in adulthood. Policy-deciders seeking to promote economic growth and to address various psychological and medico-social disorders must take into consideration the fact that appropriate investment in child health as regards SAM is an essential means to achieve this.

Preserved motor skill learning in acute stroke patients.

Recovery is dynamic during acute stroke, but whether new motor skills can be acquired with the paretic upper limb (UL) during this recovery period is unknown. Clarifying this unknown is important, because neurorehabilitation largely relies on motor learning. The aim was to investigate whether, during acute stroke, patients achieved motor skill learning and retention with the paretic UL. Over 3 consecutive days (D1-D3), 14 patients practiced with their paretic UL the CIRCUIT, a motor skill learning task with a speed/accuracy trade-off (SAT). A Learning Index (LI) was used to quantify normalised SAT changes in comparison with baseline. Spontaneous motor recovery was quantified by another task without SAT constraint (EASY), by grip force (GF), and the Box and Blocks test (BBT). In patients, CIRCUIT LI improved 98% ± 66.2 (mean ± SD). This improvement was similar to that of young healthy individuals (n = 30) who trained with a slightly different protocol for 3 consecutive days (83.8% ± 58.8%). Generalisation of SAT gains to an untrained circuit was observed in both groups. From D1 to D3, stroke patients improved their performance on EASY, while changes in GF and BBT were heterogeneous. During acute stroke, patients retained SAT gains for a motor skill learned with the paretic UL in a manner similar to that of healthy individuals. These results demonstrate acute stroke patients achieved motor skill learning and retention that exceeded paretic UL improvements explained by spontaneous recovery.

Paroxysmal Kinesigenic Dyskinesia as the Presenting and Only Manifestation of Multiple Sclerosis after Eighteen Months of Follow-Up.

Other than tremor, movement disorders are uncommon in multiple sclerosis. Among these uncommon clinical manifestations, paroxysmal kinesigenic dyskinesia is the most frequently reported. It is characterized by episodic attacks of involuntary movements that are induced by repetitive or sudden movements, startling noise or hyperventilation. The diagnosis is essentially clinical and based on a good observation of the attacks. It is very easy to misdiagnose it. We describe the case of a young female patient who presented paroxysmal kinesigenic dyskinesia as the first and only clinical manifestation of multiple sclerosis, with no recurrence of attacks nor any other neurologic symptom after eighteen months of follow-up.

Contrast-associated transient cortical blindness: three cases with MRI and electrophysiology findings.

Transient cortical blindness (TCB) is a rare but striking complication following contrast agent injection. TCB might be secondary to a direct toxicity of the contrast agent, leading to an osmotic disruption of the blood-brain barrier (BBB), with a preferential involvement of the posterior circulation and occipital cortex. We report a series of three patients with contrast medium-associated TCB (intra-arterial injection of non-ionic contrast agent during diagnostic cerebral angiography for two of them and coronary angioplasty for the other one). In two patients, the magnetic resonance imaging (MRI) was unremarkable; in the other patient, typical MRI findings were observed, with FLAIR hyperintensities in the right occipital cortex and decreased apparent diffusions coefficient (ADC). Interestingly, this patient also presented posterior rhythmic epileptiform activities on electroencephalogram during the first 36 h. Visual evoked potentials (VEPs) showed normal retinal potential, but a massive destructuration of the later potentials of the cortical origin. To our knowledge, this is the first time that VEPs acquired during TCB are reported. We discuss these findings with respect to the pathophysiology of TCB.

Ferroportin Q248H mutation, hyperferritinemia and atypical type 2 diabetes mellitus in South Kivu.

BACKGROUND: The ferroportin Q248H mutation is relatively common in sub-Saharan Africa. No previous study examined its relationship with atypical diabetes mellitus (DM) in this area. OBJECTIVE: To determine the potential interactions between ferroportin Q248H mutation, hyperferritinemia and DM in South Kivu (RDC). METHODOLOGY: Presence of ferroportin Q248H mutation and iron status were investigated in diabetic patients (n=179, age (mean) 57.7 years, CRP (median) 0.16 mg/L) and non-diabetic subjects (n=86, age 44.5 years, CRP 0.07 mg/L) living in the city of Bukavu. Hyperferritinemia was considered for values greater than 200 and 300 µg/L in women and in men, respectively. RESULTS: The prevalence of ferroportin Q248H mutation [12.1%] was non-significantly higher in diabetics than non-diabetics [14.0% vs. 8.1%, p=0.17]. Similarly, hyperferritinemia frequency was higher in diabetic patients with Q248H mutation [44.0% vs. 14.3%, p=0.16] and in mutation carriers [37.0% vs 16.5%, p=0.001] than in the control groups, respectively. The association between Q248H mutation and DM was nevertheless not significant [adjusted OR 1.70 (95% CI: 0.52-5.58), p=0.37], whereas hyperferritinemia [OR 2.72 (1.24-5.98), p=0.01] showed an independent effect after adjustment for age and metabolic syndrome. CONCLUSIONS: The present work suggests a potential association between abnormal iron metabolism, ferroportin Q248H mutation and atypical DM in Africans, which may be modulated by environmental factors.
