BACKGROUND
Six-pyruvoyl-tetrahydrobiopterin synthase (6-PTPS) deficiency is an inherited metabolic disorder which results in tetrahydrobiopterin (BH4) deficiency causing hyperphenylalaninemia.
OBJECTIVEThis study aimed to describe the clinical, biochemical, and radiologic profiles, and neurologic and developmental outcomes of patients diagnosed with 6-pyruvoyl tetrahydrobiopterin (PTPS) deficiency through newborn screening and confirmed by BH4 loading test, pterin analysis, and gene sequencing who were following-up with the metabolic team.
METHODSThe research was a single-center descriptive case series study design that was done at the Philippine General Hospital, a tertiary government hospital. The clinical, biochemical, radiologic profiles and neurodevelopmental evaluation of each patient were described.
RESULTSNine patients from 1 year 2 months to 14 years 5 months of age were enrolled in the study. Clinical manifestations before treatment were hypotonia, poor suck, and seizure. The most common clinical manifestation even after treatment initiation was seizure. The mean phenylalanine level on newborn screening was 990.68 umol/L, but after treatment was started, mean levels ranged from 75.69 to 385.09 umol/L. Two of the patients had focal atrophy of the posterior lobe on brain imaging. Pathogenic variants on molecular analysis were all missense, with two predominant variants, c.155A>G and c.58T>C. Eight of the nine patients had varying degrees of developmental delay or intellectual disability, while the remaining patient had signs of a learning disorder.
CONCLUSIONNewborn screening has played a crucial role in the early identification and management of patients with hyperphenylalaninemia due to 6-PTPS deficiency. Confirmation of diagnosis through determination of DHPR activity, urine pterins and/or molecular analysis is necessary for appropriate management. However, despite early initiation of treatment, neurodevelopmental findings of patients with 6-PTPS deficiency were still unsatisfactory.

2.Advances in the diagnosis and treatment of glycogen storage disease type Ⅱ
Journal of Apoplexy and Nervous Diseases 2025;42(5):395-400
Glycogen storage disease type Ⅱ (GSD Ⅱ), also known as Pompe disease, is a common autosomal recessive lysosomal storage disease with predominantly muscle tissue involvement, and it is caused by defects in the GAA gene which encode acid α-D-glucosidase in lysosomes. According to the age of onset and the main organs involved, it is classified into infant-onset Pompe disease (IOPD) and late-onset Pompe disease(LOPD). The diagnosis of this disease depends on the reduction in GAA enzyme activity, the detection of GAA gene mutations, and muscle tissue biopsy, and early diagnosis and treatment are crucial for prognosis. Recombinant human GAA(rhGAA) enzyme replacement therapy prepared by the gene recombination technology is currently the main disease-modifying treatment method for Pompe disease, among which the earliest drug alglucosidase α has shown good efficacy in improving muscle strength and respiratory function and prolonging survival time, and the new-generation rhGAA drugs avalglucosidase α and cipaglucosidase alfa provide new options, especially for patients with poor outcomes and severe symptoms. Substrate ablation therapy and gene therapy are still under exploration, and disease-modifying therapies combined with nutritional and exercise therapies and multidisciplinary long-term management will achieve twice the result with half the effort.

3.Advances in the treatment of mitochondrial diseases
Journal of Apoplexy and Nervous Diseases 2025;42(5):427-433
Mitochondrial diseases are a group of hereditary disorders characterized by impaired oxidative phosphorylation in the mitochondrial respiratory chain caused by defects in either mitochondrial DNA or nuclear DNA, and such diseases have complex and diverse clinical manifestations and often involve multiple organs and systems, with the main manifestation of lesions in the nervous system and muscles due to their high energy demands. At present, there is still a lack of effective therapies for most mitochondrial diseases, and therefore, multidisciplinary management is essential in clinical practice, integrating various therapeutic approaches to provide personalized treatment regimens for patients with mitochondrial diseases. The primary treatment principle involves the timely correction of pathological and physiological abnormalities through pharmacological interventions, dietary modifications, and exercise management, along with the prompt treatment of system-specific impairments and the prevention of potential complications.

4.Managements of migraine from a patient-centered perspective
Journal of Apoplexy and Nervous Diseases 2025;42(7):579-582
Migraine is the most common neurological disorder with the highest disease burden, while the current outpatient diagnosis and treatment model cannot meet the requirements for reducing the disease burden of migraine, and it is necessary to reexamine its management from a patient-centered perspective. It should be recognized that the course of migraine is a dynamic process,and some clinical manifestations that are not included in the diagnostic criteria are meaningful for diagnosis.Several risk factors for the chronicity of migraine have been identified.In addition, various comorbidities can also affect diagnosis and treatment,and it is still unable to reliably predict the treatment response of migraine.Therefore, the management of migraine requires continuous revision of diagnosis and “trial-and-error” treatment.

5.Research advances in nonconvulsive status epilepticus
Journal of Apoplexy and Nervous Diseases 2025;42(8):711-717
Nonconvulsive status epilepticus (NCSE) is a state of persistent epileptic seizure characterized by disturbance of consciousness or major neurological deficits, without obvious limb convulsions. Due to a lack of obvious clinical manifestations and the potential risk of neurological damage, current research focuses on rapid identification, accurate classification, and optimization of treatment strategies. Since there is a lack of obvious motor symptoms in NCSE, it is difficult for clinicians to quickly identify the disease through traditional signs, which poses great challenges to diagnosis, and underdiagnosis may lead to delayed treatment and poor prognosis. This article systematically reviews the epidemiological characteristics, clinical manifestations, and key diagnostic points of NCSE and discusses existing treatment regimens and prognosis, in order to provide a reference for clinical practice.

BACKGROUND OF THE STUDY
Post-obstructive diuresis (POD) is a common diagnosis among urologic patients that is medically diagnosed and managed. It is defined as urine production exceeding 200 mL per hour for two consecutive hours or producing greater than 3 L of urine in 24 hours. There is limited data on the risk factors of developing POD, but the need to identify such is important to prevent its complications such as dehydration, electrolyte imbalance, acute renal failure and even death.
OBJECTIVESThe study aims to identify clinical and renal predictors of developing POD. It also seeks to show the outcome of patients diagnosed with POD and its correlation with medical management.
METHODThis is a retrospective study of all patients diagnosed with POD centered in the University of Santo Tomas Hospital from January 2017 to December 2018. Renal parameters such as serum creatinine, sodium, potassium, urea and ionized calcium were analyzed. Urinalysis and arterial blood gases were also noted and correlated.
RESULTSAmong a total of 106 patients with obstruction, 28.32% developed POD after decompression. The mean age is 58.2 ± 13.89, and most are male. Patients with POD have significantly longer days of obstruction (14 days, p = 0.049) compared to non-POD. Overweight patients comprise a significantly larger proportion of patients who had POD (p =CONCLUSION
POD occurs more likely among patients with a baseline AKI, low level of eGFR, longer duration of obstructions beyond 14 days and those with prostate cancer. Serum sodium and creatinine were higher among patients with POD. POD is associated with prolonged hospital stay, but obstruction relief leads to renal function improvement.

INTRODUCTION:
The National Institute of Health and Care Excellence (NICE) has defined the terms, 'acute coronavirus disease 2019' (COVID-19), 'ongoing symptomatic COVID-19' and 'post-COVID-19 syndrome', with the latter two described as having persistent symptoms after the onset of COVID-19 symptoms for 4-12 weeks and >12 weeks, respectively. Persistent symptoms can either be due to the after-effects of COVID-19 or new-onset diseases after acute COVID-19. All symptoms observed beyond 4 weeks after the onset of COVID-19 need not be present at the time of onset. Previous studies on persistent post-COVID-19 symptoms have not mentioned new-onset diseases after acute COVID-19, and only a select few studies have discussed such new-onset symptoms.
METHODS:
Ninety-five patients who attended the post-COVID-19 clinic completed the requisite follow-up till 16 weeks after COVID-19 symptom onset. Data was recorded on a predesigned proforma. Necessary investigations were conducted to rule out any other cause of persistent symptoms.
RESULTS:
Fatigue (62.1%), breathlessness (50.5%) and cough (27.4%) were the most common symptoms present beyond 4 weeks after the onset of COVID-19 symptoms. Forty-nine (51.57%) patients developed post-COVID-19 syndrome - their severity of symptoms (odds ratio [OR] 17.77) and longer duration of hospital stay (OR 1.095) during acute disease were significantly associated with the development of post-COVID-19 syndrome. During follow-up, 25 patients developed new-onset symptoms, such as diabetes mellitus, hypertension and idiopathic tachycardia.
CONCLUSION
Patients can have persistent symptoms, new-onset symptoms and new-onset diseases after recovery from acute COVID-19.

INTRODUCTION:
Rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibody (ACPA) are used in the diagnosis and prognostication of rheumatoid arthritis (RA). We wanted to determine the specific contributions of RF and ACPA to the biological nature of RA and whether they act synergistically.
METHODS:
We identified 731 patients from our prospective multi-ethnic RA cohort and categorised them into four groups: ACPA-positive, RF-positive, doubly positive and doubly negative. We compared the demographics, Disease Activity Score-28, Health Assessment Questionnaire score, quality of life using Short Form 36 and the use of prednisolone and disease-modifying antirheumatic drugs (DMARDs) of these patient groups.
RESULTS:
Four hundred and ninety-one patients (67.2%) were ACPA+RF+, 54 (7.4%) were ACPA+RF-, 82 (11.2%) were ACPA-RF+ and 104 (14.2%) were ACPA-RF-. Mean disease duration before the study entry was not different in the four groups. Patients with older age of onset were less likely to be positive for RF and ACPA. Fewer ACPA+RF+ patients were in remission compared to those in the other groups ( P < 0.05). Erythrocyte sedimentation rate (ESR) was higher at study entry in the ACPA+RF+ group (40.4 mm/h vs. 30.6-30.9 mm/h, P < 0.05). Prednisolone and number of DMARDs used were higher in the ACPA+RF+ group compared to the doubly negative group. There were no differences in the functional status and quality of life.
CONCLUSIONS
RA patients who were positive for both ACPA and RF had lower remission rate, higher baseline ESR and required more corticosteroid and DMARD treatment compared to those who were singly positive or doubly negative. Being doubly positive confers a worse outcome to RA patients.
