Seguimiento a lo largo plazo de marcadores analíticos y radiológicos de los pacientes diabéticos con sospecha clínica de osteomielitis tras el cierre completo de su lesión
(2020) Tardaguila García, Aroa; Lázaro Martínez, José Luis
La osteomielitis de Pie Diabético representa aproximadamente el 50,0% delas infecciones de las úlceras de Pie Diabético, siendo la primera causa de amputación menor y mayor de los pacientes afectados. La amputación mayor en pacientes diabéticos se asocia a elevados costes sociosanitarios ya una tasa de mortalidad a los 2 y 5 años del 48,0% y del 68,0%,respectivamente. En la actualidad, no existe un consenso sobre los criterios diagnósticos de la osteomielitis de Pie Diabético y esto en ocasiones se traduce en un retraso terapéutico. De igual manera, la ausencia de indicadores diagnósticos y evolutivos de la osteomielitis de Pie Diabético no permite evaluar con claridad la ventaja terapéutica del tratamiento quirúrgico frente al médico. Además, aún no se han definido unos criterios claros acerca de la curación de la osteomielitis de Pie Diabético, que permitirían definir indicadores de evolución y resolución basados en marcadores analíticos y radiológicos, facilitando el tratamiento y el seguimiento de esta enfermedad, reduciendo los costes de tratamiento, las amputaciones y las tasas de mortalidad...
Analysis of Plantar Pressure Pattern after Metatarsal Head Resection. Can Plantar Pressure Predict Diabetic Foot Reulceration?
(Journal of Clinical Medicine, 2021) García Madrid, Marta; García Álvarez, Yolanda; Álvaro Afonso, Francisco Javier; García Morales, Esther Alicia; Tardaguila García, Aroa; Lázaro Martínez, José Luis
To evaluate the metatarsal head that was associated with the highest plantar pressure after metatarsal head resection (MHR) and the relations with reulceration at one year, a prospective was conducted with a total of sixty-five patients with diabetes who suffered from the first MHR and with an inactive ulcer at the moment of inclusion. Peak plantar pressure and pressure time integral were recorded at five specific locations in the forefoot: first, second, third, fourth, and fifth metatarsal heads. The highest value of the four remaining metatarsals was selected. After resection of the first metatarsal head, there is a displacement of the pressure beneath the second metatarsal head (p < 0.001). Following the resection of the minor metatarsal bones, there was a medial displacement of the plantar pressure. In this way, plantar pressure was displaced under the first metatarsal head following resection of the second or third head (p = 0.001) and under the central heads after resection of the fourth or fifth metatarsal head (p < 0.009 and p < 0.001 respectively). During the one-year follow-up, patients who underwent a metatarsal head resection in the first and second metatarsal heads suffered transfer lesion in the location with the highest pressure. Patients who underwent a minor metatarsal head resection (second–fifth metatarsal heads) showed a medial transference of pressure. Additionally, following the resection of the first metatarsal head there was a transference of pressure beneath the second metatarsal head. Increase of pressure was found to be a predictor of reulceration in cases of resection of the first and second metatarsal heads.
Microbiological culture combined with PCR for the diagnosis of onychomycosis: Descriptive analysis of 121 patients
(Mycoses, 2023) Navarro Pérez, David; García Oreja, Sara; Tardaguila García, Aroa; León Herce, Diego; Álvaro Afonso, Francisco Javier; Lázaro Martínez, José Luis
Background: Onychomycosis is the most common nail pathology, involving various pathogens such as dermatophytes, moulds and yeasts. Objective: The objective of this study was to observe the prevalence of onychomycosis, analyse the most appropriate diagnostic test, and assess the distribution of pathogens based on age, sex, quarter of the year, duration of symptoms and previous treatment. Methods: Retrospectively, mycological culture and PCR data and results were collected from 121 patients. Results: Of the 121 samples, 57% (69/121) tested positive when both microbiological study techniques were combined. The prevalence of onychomycosis was higher when PCR was performed (52.1%) compared to microbiological culture (33.1%). Among the 81 samples negative by microbiological culture, 31 were positive by PCR. Similarly, of the 58 samples negative by PCR, eight were positive by microbiological culture. Diagnostic accuracy data (with 95% confidence intervals) for PCR, using microbiological culture as the gold standard, were as follows: sensitivity of 0.8, specificity of 0.62, positive predictive value of 0.51 and negative predictive value of 0.86. The most frequently identified pathogen was Trichophyton rubrum, and the hallux nail plate was the most commonly affected location. However, no statistically significant associations were found between sex, age, quarter of the year and affected area with culture and PCR results. Conclusion: Combining microbiological culture and PCR can increase the detection rate of onychomycosis and help avoid false-negative results.
Analyses of transcutaneous oxygen pressure values stratified for foot angiosomes to predict diabetic foot ulcer healing
(Journal of Tissue Viability, 2023) López-Moral M; García-Madrid Martín De Almagro, Marta; Molines Barroso, Raúl Juan; García Álvarez, Yolanda; Tardaguila García, Aroa; Lázaro Martínez, José Luis; Elsevier
Aims: Previous research suggested that diabetic foot ulcer (DFU) location could affect transcutaneous oxygen pressure (TcPO2) values following the angiosome concept. Up to our knowledge no studies have yet analyzed if the location of a diabetic foot ulcer can be a confounding factor that modifies TcPO2 values. The primary aim of this study was to compare the potential healing prognosis of TcPO2 differentiated for diabetic foot ulcers in different angiosome locations. Methods: a 2-years observational cohort prospective study was performed in 81 patients with diabetic foot ulcers. Transcutaneous oxygen pressure measurements were performed at baseline by placing the electrode on two different angiosomes: dorsal zone of the foot (dorsalis pedis angiosome) and between the navicular bone and the tibial malleolus (posterior tibial angiosome). The main outcome was establishing the effectiveness of TcPO2 measurements (dorsalis pedis angiosome and posterior tibial angiosome) for predicting DFU healing. Results: Transcutaneous oxygen pressure probe placed in the dorsum of the foot (dorsalis pedis angiosome) yielded a sensitivity (S) of 95 % and specificity (SP) of 73 %, and an area under the curve (AUC) of 0.902 (p < 0.001 [0.84–0.96]) for ulcers located in the forefoot and toes; while TcPO2 placed in the posterior tibial angiosome yielded an S of 100 % and SP of 85 % and an AUC of 0.894 (p <0.001 [0-822-0.966]) for DFU located in the midfoot and heel. Conclusion: This study suggests that angiosome-guided TcPO2 contributes to a prognosis of successful foot ulcer healing.
Efficacy of cryotherapy for plantar warts: A systematic review and meta‐analysis
(Dermatologic Therapy, 2022) García Oreja, Sara; Álvaro Afonso, Francisco Javier; Tardaguila García, Aroa; López Moral, Mateo; García Madrid, Marta; Lázaro Martínez, José Luis
Recent systematic reviews of plantar warts continue to consider cryotherapy as one of the treatments of choice, but this method appears to have lower cure rates than alternative treatments. A systematic review using meta-analyses of the efficacy of cryotherapy in plantar warts treatment was performed. Systematic electronic searches were conducted. The primary endpoint was complete clearance of plantar warts. Risk-of-bias assessment was based on Cochrane Handbook recommendations. Meta-analyses used Review Manager v5.4.1 software. Cryotherapy appears to have lower cure rates than other treatments (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.12–0.78) with substantial heterogeneity (I2 = 80%). A second subgroup analysis had low heterogeneity (I2 = 28.2%). Subgroup analysis showed that plantar wart cure rates were significantly lower with cryotherapy compared to the physical treatment group (OR 0.05, 95% CI 0.01–0.49) with substantial heterogeneity (I2 = 79%), and antiviral, chemotherapy, and retinoid group (OR 0.30, 95% CI 0.14–0.66) without heterogeneity (I2 = 0%). Intralesional versus spray-on cryotherapy appears to be more effective (OR 0.21, 95% CI 0.09–0.48). No difference in efficacy between two rounds of 10-s and four rounds of 5-s freeze–thaw cycles in cryotherapy was found. Evidence of the superiority of antivirals and chemotherapy over cryotherapy in the treatment of plantar warts was found. However, no evidence supports the superiority or inferiority of cryotherapy compared to other treatments.
Intra-Observer and Inter-Observer Reliability of Ankle Circumference Measurement in Patients with Diabetic Foot: A Prospective Observational Study
(Journal of Clinical Medicine, 2023) Montoro Cremades, David; Tardaguila García, Aroa; Navarro Pérez, David; García Álvarez, Yolanda; López Moral, Mateo; Lázaro Martínez, José Luis
Inflammation, being a typical response to vascular tissue alterations, induces variations in tissue oxygen diffusion pressure. Diabetic microangiopathy, an inflammatory process, is characterized by an increase in vascular flow at rest, reduced venous and arteriolar responses, and increased capillary permeability, resulting in oedema development, decreased transcutaneous oxygen pressure, and increased transcutaneous carbon dioxide pressure. This phenomenon potentially hampers ulcer healing. Although the figure-of-eight method has proven to be a reliable, valid, quick, and efficient test for assessing foot and ankle measurements in patients with oedema and compromised skin integrity, it has not been studied in patients with diabetic foot. The aim of this study was to determine and compare the intra- and inter-observer variabilities of the figure-of-eight method in patients with diabetic foot. A prospective observational and cross-sectional study was undertaken, involving sixty-one subjects from a specialized Diabetic Foot Unit. Three investigators with varying levels of experience independently measured the subjects to assess both intra-observer and inter-observer variability. The evaluation was conducted using the Intraclass Correlation Coefficient (ICC). In the statistical analysis, an ICC of 0.93, adjusted using a 95% confidence interval (CI), was obtained for inter-observer reliability ICC, indicating excellent reliability among observers. Furthermore, an ICC of 0.98 with a 95% CI was obtained for the intra-observer reliability analysis, indicating excellent reliability. The results support using this test during the clinical management of oedema in patients with diabetic foot. The absence of an objective, fast, and readily available diagnostic method for oedema in diabetic foot patients in clinical practice might pose a limitation. Subsequent research should tackle this issue and explore the correlation between ankle perimeter measurements and other clinical outcomes in diabetic foot patients, including wound healing and quality of life.
Bacterial Diversity and Antibiotic Resistance in Patients with Diabetic Foot Osteomyelitis
(Antibiotics, 2023) Álvaro Afonso, Francisco Javier; García Álvarez, Yolanda; Tardaguila García, Aroa; García Madrid, Marta; López Moral, Mateo; Lázaro Martínez, José Luis
This study analysed the bacterial diversity, antibiotic susceptibility, and resistance in patients with complications of diabetic foot osteomyelitis (DFO). A retrospective observational study was carried out between September 2019 and September 2022 and involved 215 outpatients with a diagnosis of DFO at a specialized diabetic foot unit. A total of 204 positive bone cultures were isolated, including 62.7% monomicrobial cultures, and 37.3% were formed with at least two microorganisms. We observed that Proteus spp., Coagulase-negative staphylococci (CoNS), Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Corynebacterium were the most frequently isolated microorganisms and accounted for more than 10% of the DFO cases. With stratification by Grampositive (GP) and Gram-negative (GN) bacteria, we observed that 91.6% of cultures presented at least one GP bacteria species, and 50.4% presented at least one GN bacteria species. The most common GP species were CoNS (29%), S. aureus (25.8%), and Corynebacterium spp. (14%). The most frequent GN species consisted of Proteus spp. (32%), P. aeruginosa (23.3%), and E. coli (17.5%). The main antibiotics with resistance to GP-dominated infections were penicillins without �-lactamase inhibitor, and those in GN-dominated infections were sulfonamides and penicillins without �-lactamase. Significant differences were not observed in mean healing time in DFU with acute osteomyelitis (12.76 weeks (4.50;18)) compared to chronic osteomyelitis (15.31 weeks (7;18.25); p = 0.101) and when comparing cases with soft tissue infection (15.95 (6;20)) and those without such an infection (16.59 (7.25;19.75), p = 0.618). This study shows that when treatment of DFO is based on early surgical treatment, the type of DFO and the presence of soft infection are not associated with different or worse prognoses.
Onychomycosis associated with diabetic foot syndrome: A systematic review
(Mycoses, 2023) Navarro Pérez, David; Tardaguila García, Aroa; García Oreja, Sara; López Moral, Mateo; García-Madrid Martín De Almagro, Marta; Lázaro Martínez, José Luis
Background A systematic review was conducted to investigate the prevalence of onychomycosis in patients with diabetes. The association of onychomycosis with risk factors in patients with diabetic foot syndrome was also examined. Methods The recommendations in the preferred reporting items for systematic reviews and meta-analysis (PRISMA) checklist were applied, and the included studies were assessed using the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) method. Searches were conducted in October 2022 using PubMed (Medline) and Scopus for clinical studies, clinical trials, comparative studies, observational studies, and randomised clinical trials or controlled clinical trials addressing the prevalence and consequences of onychomycosis in patients with diabetes, diagnoses or treatments. Two authors performed the study selection and data extraction, and any discrepancies between the two reviewers were resolved through discussion with a third reviewer. Results The systematic review included ten studies that met the inclusion criteria, and these studies enrolled 5664 patients with diabetes. Among these patients, 29.18% had onychomycosis that was mainly caused by Trichophyton rubrum. A significant association was found between the occurrence of onychomycosis and the presence of diabetic neuropathy (p = .012) and elevated glycosylated haemoglobin values (p = .039). There was no significant association between onychomycosis and ulceration (p = .185). Eight studies had a grade 4 level of evidence and a grade C recommendation, and one study had a grade 1b level of evidence and a grade A recommendation. Conclusion The information described in the literature is insufficient and heterogeneous regarding the association of risk factors and ulceration in patients with diabetic foot compared with developing onychomycosis. There is also a need to implement onychomycosis diagnostic testing instead of relying only on a clinical diagnosis. Additional prospective, randomised, comparative studies are needed to increase the quality of studies in the literature.
Complications associated with the approach to metatarsal head resection in diabetic foot osteomyelitis
(International Wound Journal, 2018) Tardaguila García, Aroa; Sanz Corbalán, Irene; Molines Barroso, Raúl Juan; Álvaro Afonso, Francisco Javier; García Álvarez, Yolanda; Lázaro Martínez, José Luis
The aim of this study was to evaluate the recovery time and the development of complications in the dorsal and plantar approach to metatarsal head resections (MHR) in patients with diabetic foot ulcers complicated by osteomyelitis. A retrospective study was carried out involving 108 patients who underwent MHRs for the treatment of diabetic foot osteomyelitis. Two cohorts were defined: dorsal approach with incision closed with sutures and plantar approach with ulcer healed using conservative treatment. The main outcomes were the weeks until healing and complications related to the approaches. Fifty-three patients (49.1%) underwent a plantar approach and 55 (50.9%) a dorsal approach. Both approaches rendered similar healing times. However, the patients undergoing a dorsal approach developed more post-surgical complications than patients treated through a plantar approach. The dorsal approach intervention was performed on smaller and shallower ulcers; however, more complications developed at follow up using this approach than through a plantar approach for MHR complicated with osteomyelitis.
A comparison of hyperspectral imaging with routine vascular noninvasive techniques to assess the healing prognosis in patients with diabetic foot ulcers
(J Vasc Surg, 2022) López Moral, Mateo; García Álvarez, Yolanda; Molines Barroso, Raúl Juan; Tardaguila García, Aroa; García-Madrid Martín De Almagro, Marta; Lázaro Martínez, José Luis
Objective: To compare the potential healing prognosis of the different routine noninvasive techniques implemented in the International Working Group Diabetic Foot Guidelines with the novel use of hyperspectral imaging (HSI) in patients with diabetic foot ulcers (DFUs). Methods: Twenty-one patients with active DFUs participated in this 1-year prospective study in a specialized diabetic foot unit between December 2018 and January 2020. HSI was performed at baseline to quantify tissue oxygenation and should be presented on an anatomical map by analyzing the following parameters: (1) oxygen saturation of the hemoglobin, (2) tissue hemoglobin index, (3) the near-infrared perfusion index, and (4) tissue water index. In addition, transcutaneous oxygen pressure (TcpO2), systolic toe and ankle pressures, ankle-brachial index, and toe-brachial index values were calculated for the ulcerated limb. The primary outcome measure was wound healing, defined as complete epithelization without any drainage confirmed for at least 10 days after closure was first documented at 24 weeks. Results: During the follow-up period 14 patients (66.66 %) healed and 7 patients did not heal (33.3%) by 24 weeks. The TcpO2 optimal cut-off point as determined by a balance of sensitivity and specificity of 28.5 mm Hg that yielded a sensitivity of 91% and a specificity of 100%, and area under the curve of 0.989 (P = .005; 95% confidence interval [CI], 0.945-1.000). Followed by the oxygen saturation of the hemoglobin optimal cut-off point as determined by a balance of sensitivity and specificity of 48.5 mm Hg that yielded a sensitivity of 93% and a specificity of 0.71%, and area under the curve of 0.932 (P = .013; 95% CI, 0.787-1.000). The logistic regression analyses showed that TcpO2 was the only variable associated with wound healing at 24 weeks (P < .001; 95% CI, 0.046-0.642). Conclusions: The HSI was shown to be effective in the prognosis of DFU healing compared with other noninvasive test; only TcpO2 values resulted in better diagnosis potential in wound healing.
